Advanced Log Parser Charts Part 3 - Missing Office Web Components for Charting

In Part 3 of this series, I'll explain what to do when you're missing the Office Web Components that are required for creating the charts that I have been demonstrating in this series.

Here's a brief explanation of the symptoms: you try a simple query that will create a chart like the following example:

logparser.exe "SELECT Date,COUNT(*) AS Hits INTO HitsByDay.gif FROM *.log GROUP BY Date ORDER BY Date" -i:W3C -o:CHART -chartType:Line -legend:off -chartTitle:"Hits By Day"

And you get the following error message:

Error creating output format "CHART": This output format requires a licensed Microsoft Office Chart Web Component to be installed on the local machine

More often than not, this simply means that you have Office 2007 or Office 2010, which do not contain the Office Web Components that are used by Log Parser to create charts. Fortunately, you can download the missing components from the following URL on Microsoft's website:

Office 2003 Add-in: Office Web Components
http://www.microsoft.com/en-us/download/details.aspx?id=22276

When you run the installation, you will see the following license agreement:

When you check the box to accept the license agreement and click Install, you will eventually receive the following dialog box to let you know that the Office 2003 Web Components have been installed:

Once you have the Office 2003 Web Components installed, you can run the same query successfully:

logparser.exe "SELECT Date,COUNT(*) AS Hits INTO HitsByDay.gif FROM *.log GROUP BY Date ORDER BY Date" -i:W3C -o:CHART -chartType:Line -legend:off -chartTitle:"Hits By Day"

Statistics:
-----------
Elements processed: 123330
Elements output: 14
Execution time: 0.57 seconds

Note: The above query generates the following somewhat uninteresting chart:

That being said, the point of this blog was to let you know how to get charting back, not how to make pretty charts. I'll save pretty charts for a future blog. ;-]

Configuring FTP Client Certificate Authentication in FTP 7

We had a customer question the other day about configuring FTP Client Certificate Authentication in FTP 7.0 and  in FTP 7.5. It had been a while since the last time that I had configured those settings on an FTP server, so I thought that it would be great to re-familiarize myself with that feature. To my initial dismay, it was a little more difficult than I had remembered, because there are a lot of parts to be configured.

That being said, there are a few primary activities that you need to know about and configure correctly:

I will explain each of those in this blog, although I will defer some of the details for Active Directory mapping to an excellent blog series that I discovered by Vivek Kumbhar.

Configuring the FTP Service

There are several settings that you need to configure for the FTP server; unfortunately there is no user interface for those settings, so you might want to familiarize yourself with the following settings:

At first I had made a batch file that was configuring these settings by using AppCmd, but I eventually abandoned that script and wrote the following VBScript code to configure all of the settings at one time - the only parts that you need to change is your site name and the hash value your SSL certificate, which are highlighted in yellow:

Set adminManager = CreateObject("Microsoft.ApplicationHost.WritableAdminManager")
adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST"
Set sitesSection = adminManager.GetAdminSection("system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST")
Set sitesCollection = sitesSection.Collection

siteElementPos = FindElement(sitesCollection, "site", Array("name", "ftp.contoso.com"))
If (addElementPos = -1) Then
   WScript.Echo "Element not found!"
   WScript.Quit
End If
Set siteElement = sitesCollection.Item(siteElementPos)

Set ftpServerElement = siteElement.ChildElements.Item("ftpServer")
Set securityElement = ftpServerElement.ChildElements.Item("security")

Set sslClientCertificatesElement = securityElement.ChildElements.Item("sslClientCertificates")
sslClientCertificatesElement.Properties.Item("clientCertificatePolicy").Value = "CertRequire"
sslClientCertificatesElement.Properties.Item("useActiveDirectoryMapping").Value = True

Set authenticationElement = securityElement.ChildElements.Item("authentication")
Set clientCertAuthenticationElement = authenticationElement.ChildElements.Item("clientCertAuthentication")
clientCertAuthenticationElement.Properties.Item("enabled").Value = True

Set sslElement = securityElement.ChildElements.Item("ssl")
sslElement.Properties.Item("serverCertHash").Value = "57686f6120447564652c2049495320526f636b73"
sslElement.Properties.Item("controlChannelPolicy").Value = "SslRequire"
sslElement.Properties.Item("dataChannelPolicy").Value = "SslRequire"

adminManager.CommitChanges

Function FindElement(collection, elementTagName, valuesToMatch)
   For i = 0 To CInt(collection.Count) - 1
      Set element = collection.Item(i)
      If element.Name = elementTagName Then
         matches = True
         For iVal = 0 To UBound(valuesToMatch) Step 2
            Set property = element.GetPropertyByName(valuesToMatch(iVal))
            value = property.Value
            If Not IsNull(value) Then
               value = CStr(value)
            End If
            If Not value = CStr(valuesToMatch(iVal + 1)) Then
               matches = False
               Exit For
            End If
         Next
         If matches Then
            Exit For
         End If
      End If
   Next
   If matches Then
      FindElement = i
   Else
      FindElement = -1
   End If
End Function

Once you have configured your FTP settings, you should have an FTP site that resembles the following in your ApplicationHost.config file:

<site name="ftp.contoso.com" id="2">
   <application path="/">
      <virtualDirectory path="/" physicalPath="c:\inetpub\ftproot" />
   </application>
   <bindings>
      <binding protocol="ftp" bindingInformation="*:21:" />
   </bindings>
   <ftpServer>
      <security>
         <ssl serverCertHash="57686f6120447564652c2049495320526f636b73"  ssl128="false"  controlChannelPolicy="SslRequire"  dataChannelPolicy="SslRequire" />
         <authentication>
            <basicAuthentication enabled="false" />
            <anonymousAuthentication enabled="false" />
            <clientCertAuthentication enabled="true" />
         </authentication>
         <sslClientCertificates  clientCertificatePolicy="CertRequire"  useActiveDirectoryMapping="true" />
      </security>
   </ftpServer>
</site>

More details about these settings can be found in the configuration reference articles that I mentioned in the beginning of this blog post, and additional information about configuring FTP over SSL can be found in the following walkthrough:

Configuring Active Directory Mapping

The next part of this process is kind of tricky; you need to accomplish all of the following:

  • Obtain and install a client certificate on the system where your FTP client is installed. Hare some additional notes to consider:
    • This may involve setting up your client system to trust the CA that issued your client certificate.
    • This may also involve setting up your FTP server to trust the CA that issued both your client certificate and the server certificate that you are using for your FTP site.
  • Configure Active Directory to map the client certificate to an Active Directory account.
  • Configure your FTP client to use a client certificate when connecting to your FTP server.

That makes it all sound so easy, but it can be very tricky. That being said, as I mentioned earlier, as I was putting together my notes to write this blog, I stumbled across a great blog series by Vivek Kumbhar, where he goes into great detail when describing all of the steps to set up the Active Directory mapping. With that in mind, instead of trying to rewrite what Vivek has already documented, I will include links to his blog series:

I have to give Vivek full credit where it's due - he wrote a truly great blog series, and he included a lot more detail in his blog series than I had originally planned to include in this blog. (In my humble opinion, Vivek's blog series is the best documentation that I have seen for this feature.)

Configuring your FTP Client

To test out client certificates, I used both the SmartFTP GUI-based FTP client and the MOVEit-Freely command-line FTP client; both of which I discussed in my FTP Clients blog series some time ago.

Using the SmartFTP Client

To configure the SmartFTP client, I just needed to enable and specify the correct client certificate in the properties for my connection:

Using the MOVEit-Freely FTP Client

For the MOVEit-Freely FTP client, I just needed to specify the correct parameters on the command line:

ftps.exe -z -e:on -pfxfile:administrator.pfx -pfxpw:"P@ssw0rd" -user:anonymous -password:"someone@contoso.com"

The important settings are the pfxfile and pfxpw values, where pfxfile is the name of the PFX file that holds your client certificate, and pfxpw is the password for the PFX file. (The username and password values will be ignored for the most part, because you will actually be logged in through your client certificate, so you can leave those as anonymous.)

Client Recap

For more information about these two FTP clients, see the following blog posts:

Summary

FTP client certificates are definitely a bit of a challenge to configure correctly, but it's not an impossible task to get this feature working.

Programmatically Flushing FTP Logs

I had a great question from Scott Forsyth earlier today about programmatically flushing the logs for an FTP site. Scott had noticed that there was a FlushLog method listed on the following page in the IIS Configuration Reference:

http://www.iis.net/ConfigReference/system.applicationHost/sites/site/ftpServer

Unfortunately there wasn't a code sample for that method; but as luck would have it, I had already written some code to do just that. (I love synchronicity...) With that in mind, I though that I'd post the code in a blog. In keeping with the cross-language samples that I wrote for the topics in the Configuration Reference, I thought that's I'd include several languages in this blog to make it easier for someone else to copy and paste.

C#

ConfigurationElementCollection sitesCollection = sitesSection.GetCollection();

// Locate a specific site.
ConfigurationElement siteElement = FindElement(sitesCollection,"site","name",@"ftp.contoso.com");
if (siteElement == null) throw new InvalidOperationException("Element not found!");

// Create an object for the ftpServer element.
ConfigurationElement ftpServerElement = siteElement.GetChildElement("ftpServer");
// Create an instance of the FlushLog method.
ConfigurationMethodInstance FlushLog = ftpServerElement.Methods["FlushLog"].CreateInstance();
// Execute the method to flush the logs for the FTP site.
FlushLog.Execute();
}
}

// Locate and return the index for a specific element in a collection.
private static ConfigurationElement FindElement(ConfigurationElementCollection collection, string elementTagName, params string[] keyValues)
{
foreach (ConfigurationElement element in collection)
{
if (String.Equals(element.ElementTagName, elementTagName, StringComparison.OrdinalIgnoreCase))
{
bool matches = true;
for (int i = 0; i < keyValues.Length; i += 2)

Summary

Hopefully this gives you an idea of how to call the FlushLog method. You can also use these examples to call the Start and Stop methods for FTP sites; you just need to substitute the correct method in place of the FlushLog method.

Using URL Rewrite to Insert Different Scripts Based on Browser Type

I just stumbled across a piece of sample code that I had written several months ago for a coworker, and I thought that I'd share it with everyone.

Here's the scenario: my coworker asked me if it was possible to have different client-side scripts inserted dynamically depending on the type of web browser that is being used. If the application was written in ASP.NET or some other dynamic language, then it would be trivial to determine the browser type and return the correct HTML <script> block to the client. Unfortunately, he needed the script for both static and dynamic pages, and he didn't want to modify all of his pages unless absolutely necessary.

This sounded to me like a job for a pair of outbound rules in URL Rewrite.

With the above design requirements in mind, I wrote the following sample configuration for URL Rewrite that accomplishes the following tasks:

  • If you’re using Internet Explorer, it inserts VBScript to display a popup message.
  • If you’re not using Internet Explorer, it inserts JavaScript to display a different popup message.

In order to use this sample code, you need to open the web.config file for your application and add the following code for the URL Rewrite rules. (Note: You need to disable compression in order to avoid an HTTP 500.52 error, and the following sample code does just that.)

<system.webServer>
  <rewrite>
    <outboundRules>
      <rule name="Add JavaScript" preCondition="IsNotInternetExplorer" patternSyntax="ExactMatch">
        <match filterByTags="None" pattern="&lt;/body>" />
        <action type="Rewrite" value="&lt;script language=&quot;javascript&quot;>alert('You are not using Internet Explorer!');&lt;/script>&lt;/body>" />
      </rule>
      <rule name="Add VBScript" preCondition="IsInternetExplorer" patternSyntax="ExactMatch">
        <match filterByTags="None" pattern="&lt;/body>" />
        <action type="Rewrite" value="&lt;script language=&quot;vbscript&quot;>MsgBox &quot;You are using Internet Explorer!&quot;&lt;/script>&lt;/body>" />
      </rule>
      <preConditions>
        <preCondition name="IsInternetExplorer">
          <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
          <add input="{HTTP_USER_AGENT}" pattern=".*MSIE" negate="false" />
        </preCondition>
        <preCondition name="IsNotInternetExplorer">
          <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
          <add input="{HTTP_USER_AGENT}" pattern=".*MSIE" negate="true" />
        </preCondition>
      </preConditions>
    </outboundRules>
  </rewrite>
  <urlCompression doStaticCompression="false" doDynamicCompression="false" />
</system.webServer>

The above example is what I sent to my coworker, and I intended it as an easy place to start when you just want a simple chunk of script to be inserted. It works well, but a better example would be to have it dynamically insert code for an external script file based on the browser type. This is illustrated in the following example:

<system.webServer>
  <rewrite>
    <outboundRules>
      <rule name="For Other Browsers" preCondition="IsNotInternetExplorer" patternSyntax="ExactMatch">
        <match filterByTags="None" pattern="&lt;/body>" />
        <action type="Rewrite" value="&lt;script language=&quot;javascript&quot; src=&quot;other.js&quot;>&lt;/script>&lt;/body>" />
      </rule>
      <rule name="For Internet Explorer" preCondition="IsInternetExplorer" patternSyntax="ExactMatch">
        <match filterByTags="None" pattern="&lt;/body>" />
        <action type="Rewrite" value="&lt;script language=&quot;javascript&quot; src=&quot;msie.js&quot;>&lt;/script>&lt;/body>" />
      </rule>
      <preConditions>
        <preCondition name="IsInternetExplorer">
          <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
          <add input="{HTTP_USER_AGENT}" pattern=".*MSIE" negate="false" />
        </preCondition>
        <preCondition name="IsNotInternetExplorer">
          <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
          <add input="{HTTP_USER_AGENT}" pattern=".*MSIE" negate="true" />
        </preCondition>
      </preConditions>
    </outboundRules>
  </rewrite>
  <urlCompression doStaticCompression="false" doDynamicCompression="false" />
</system.webServer>

The above sample dynamically inserts an HTML <script> block, and specifies one script file ("msie.js") for Internet Explorer a different script  file ("other.js") for all other browsers.

A simple script for a simple task - just the way I like it. ;-]

Advanced Log Parser Charts Part 2 - Using Gradient Colors for Area Charts

In Part 2 of this series, I'll show you how to customize the area chart from Part 1 to show the chart area with a gradient. More specifically, there are three different chart gradient methods that we'll take a look at in this blog post:

Before I continue, there is one quick Log Parser convention that you should realize: there are two objects that Log Parser will create and pass to your script. As you look at the sample scripts in this post, you will see these objects in use:

Object NameDescriptionExample
chartSpace This is the base chart workspace object.
// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;
chart This is equivalent to the chartSpace.Charts(0) object.
// Change the background color.
chart.PlotArea.Interior.Color = "#ffffff";

Before I get started, here's a quick review of VBScript that uses Log Parser COM objects:

Option Explicit

' Declare the variables.
Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

' Create the Log Parser objects.
Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

' Define the SQL query.
strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO _Part2.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

' Specify the chart options.
objOutputChartFormat.groupSize = "800x600"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"

' Execute the SQL statement to create the chart.
objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat

As I mentioned in Part 1 of this series, you don't have to use the COM objects, but I chose to do so for this blog series because it makes it a little easier to script. That being said, if I use one month's worth of log files from one of my low-volume websites, Log Parser and this VBScript creates the following rather ugly daily hits chart:

With all of this in mind, let's take a look at some simple configuration scripts.

Setting Fonts and Titles and Such...

The above chart really needs some help, so the first thing that we'll do is change a few things. First things first, we need to specify the name of the chart configuration script in the VBScript sample:

Option Explicit

' Declare the variables.
Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

' Create the Log Parser objects.
Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

' Define the SQL query.
strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO Part2.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

' Specify the chart options.
objOutputChartFormat.groupSize = "800x600"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"
objOutputChartFormat.config = "Part2.js"

' Execute the SQL statement to create the chart.
objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat

Next, we need to create the actual chart configuration script, which I wrote in JavaScript; you will need to save this as "Part2.js" in order to use my samples:

// Set the title above the chart.
chart.HasTitle = true;
chart.Title.Caption = "Hits by Day"

// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;

// Change the background color for the plot area.
chart.PlotArea.Interior.Color = "#f0f0f0";

// Set the font size for the chart values.
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Size = 6;

// Get the start and end dates from the X axis.
var startDate = chart.Axes(0).CategoryLabels.Item(0).Caption;
var endDate = chart.Axes(0).CategoryLabels.Item(chart.Axes(0).CategoryLabels.ItemCount-1).Caption;

// Set the caption below the chart.
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption =
"This chart shows the hits by day from "
+ startDate + " to " + endDate + ".";
chartSpace.ChartSpaceTitle.Font.Size = 10;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Set the style and caption for the Y axis.
chart.Axes(0).Font.Size = 8;
chart.Axes(0).HasTitle = true;
chart.Axes(0).Title.Caption = "Dates";
chart.Axes(0).Title.Font.Size = 9;

// Set the style and caption for the X axis.
chart.Axes(1).Font.Size = 7;
chart.Axes(1).HasTitle = true;
chart.Axes(1).Title.Caption = "Hits";
chart.Axes(1).Title.Font.Size = 9;

This chart configuration script does several things:

  • Sets the title above the chart to "Hits by Day"
  • Sets a black border style for the chart
  • Sets the background color for the plot area to a light gray
  • Sets the font size for the chart values to 6-point
  • Sets the caption below the chart for the start and end date
  • Sets the font styles and captions for the Y and Y axes

When you run the VBScript, the resulting chart looks like the following:

This looks a little more legible, but now let's look at setting some colors.

Setting a One-Color Gradient

Using the same JavaScript sample from earlier, we just need to make a couple of changes to the chart configuration script in order to use the SetOneColorGradient method:

// Set the title above the chart.
chart.HasTitle = true;
chart.Title.Caption = "Hits by Day"

// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;

// Change the background color for the plot area.
chart.PlotArea.Interior.Color = "#f0f0f0";

// Specify the chart gradient styles.
chart.SeriesCollection(0).Interior.SetOneColorGradient(
chartSpace.Constants.chGradientHorizontal,
chartSpace.Constants.chGradientVariantEnd,
1.0,
"#ff0000");

// Set the font size for the chart values.
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Size = 6;

// Get the start and end dates from the X axis.
var startDate = chart.Axes(0).CategoryLabels.Item(0).Caption;
var endDate = chart.Axes(0).CategoryLabels.Item(chart.Axes(0).CategoryLabels.ItemCount-1).Caption;

// Set the caption below the chart.
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption =
"This chart shows the hits by day from "
+ startDate + " to " + endDate + ".";
chartSpace.ChartSpaceTitle.Font.Size = 10;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Set the style and caption for the Y axis.
chart.Axes(0).Font.Size = 8;
chart.Axes(0).HasTitle = true;
chart.Axes(0).Title.Caption = "Dates";
chart.Axes(0).Title.Font.Size = 9;

// Set the style and caption for the X axis.
chart.Axes(1).Font.Size = 7;
chart.Axes(1).HasTitle = true;
chart.Axes(1).Title.Caption = "Hits";
chart.Axes(1).Title.Font.Size = 9;

When you run the VBScript, this renders a chart that looks like the following:

There are four parameters for the SetOneColorGradient method to look at:

ParameterDescription
GradientStyle This is a value from the ChartGradientStyleEnum enumeration, which specifies how the gradient will be displayed. For example: horizontally, vertically, diagonally, etc.
GradientVariant This is a value from the ChartGradientVariantEnum enumeration, which specifies which direction the gradient will be displayed. For example: lighter to darker, from the inside to the outside, etc.
GradientDegree This is a double value from 0.0 to 1.0, which specifies whether the gradient will range from the color to lighter or darker shades.
Color This is a string that specifies the color. This can be a commonly-named color, such as "red," "blue," etc., or this can be an RGB hexadecimal value, such as "#ff0000" (red), "#0000ff" (blue), etc. (See my 216-Color Safe Web Palette blog post for a large series of hexadecimal color values.)

Let's make some quick changes to parameters that we are passing to the SetOneColorGradient method and alter a few of the colors:

// Set the title above the chart.
chart.HasTitle = true;
chart.Title.Caption = "Hits by Day"

// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;

// Change the background color for the plot area.
chart.PlotArea.Interior.Color = "#333333";

// Specify the chart gradient styles.
chart.SeriesCollection(0).Interior.SetOneColorGradient(
chartSpace.Constants.chGradientHorizontal,
chartSpace.Constants.chGradientVariantStart,
0.0,
"#00ff00");

// Set the font size for the chart values.
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Size = 6;
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Color = "#ffffff";

// Get the start and end dates from the X axis.
var startDate = chart.Axes(0).CategoryLabels.Item(0).Caption;
var endDate = chart.Axes(0).CategoryLabels.Item(chart.Axes(0).CategoryLabels.ItemCount-1).Caption;

// Set the caption below the chart.
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption =
"This chart shows the hits by day from "
+ startDate + " to " + endDate + ".";
chartSpace.ChartSpaceTitle.Font.Size = 10;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Set the style and caption for the Y axis.
chart.Axes(0).Font.Size = 8;
chart.Axes(0).HasTitle = true;
chart.Axes(0).Title.Caption = "Dates";
chart.Axes(0).Title.Font.Size = 9;

// Set the style and caption for the X axis.
chart.Axes(1).Font.Size = 7;
chart.Axes(1).HasTitle = true;
chart.Axes(1).Title.Caption = "Hits";
chart.Axes(1).Title.Font.Size = 9;

When you run the VBScript, that results in the following considerably cooler-looking chart:

Setting a Two-Color Gradient

The SetTwoColorGradient method offers more color flexibility than the one-color gradient method, and we only need to make a couple of changes to the JavaScript for the chart configuration script in order to use the new method:

// Set the title above the chart.
chart.HasTitle = true;
chart.Title.Caption = "Hits by Day"

// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;

// Change the background color for the plot area.
chart.PlotArea.Interior.Color = "#FFFF99";

// Specify the chart gradient styles.
chart.SeriesCollection(0).Interior.SetTwoColorGradient(
chartSpace.Constants.chGradientVertical,
chartSpace.Constants.chGradientVariantStart,
"#0066FF",
"#00FFCC");

// Set the font size for the chart values.
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Size = 6;

// Get the start and end dates from the X axis.
var startDate = chart.Axes(0).CategoryLabels.Item(0).Caption;
var endDate = chart.Axes(0).CategoryLabels.Item(chart.Axes(0).CategoryLabels.ItemCount-1).Caption;

// Set the caption below the chart.
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption =
"This chart shows the hits by day from "
+ startDate + " to " + endDate + ".";
chartSpace.ChartSpaceTitle.Font.Size = 10;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Set the style and caption for the Y axis.
chart.Axes(0).Font.Size = 8;
chart.Axes(0).HasTitle = true;
chart.Axes(0).Title.Caption = "Dates";
chart.Axes(0).Title.Font.Size = 9;

// Set the style and caption for the X axis.
chart.Axes(1).Font.Size = 7;
chart.Axes(1).HasTitle = true;
chart.Axes(1).Title.Caption = "Hits";
chart.Axes(1).Title.Font.Size = 9;

When you run the VBScript, this will create the following chart:

There are four parameters for the SetTwoColorGradient method to consider:

ParameterDescription
GradientStyle This is a value from the ChartGradientStyleEnum enumeration, which specifies how the gradient will be displayed. For example: horizontally, vertically, diagonally, etc.
GradientVariant This is a value from the ChartGradientVariantEnum enumeration, which specifies which direction the gradient will be displayed. For example: lighter to darker, from the inside to the outside, etc.
Color This is a string that specifies the first color for the gradient; this can be a commonly-named color, such as "red," "blue," etc., or this can be an RGB hexadecimal value, such as "#ff0000" (red), "#0000ff" (blue), etc. (See my 216-Color Safe Web Palette blog post for a large series of hexadecimal color values.)
BackColor This is a string that specifies the second color for the gradient; this can be a value like the Color parameter.

Using a Preset Gradient

There is an additional gradient method that uses a collection of preset color palettes; this method is appropriately named SetPresetGradient. Once again, we need to make a couple of changes to the JavaScript for the chart configuration script in order to use the new method:

// Set the title above the chart.
chart.HasTitle = true;
chart.Title.Caption = "Hits by Day"

// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;

// Change the background color for the plot area.
chart.PlotArea.Interior.Color = "#EEFFDD";

// Specify the chart gradient styles.
chart.SeriesCollection(0).Interior.SetPresetGradient(
chartSpace.Constants.chGradientHorizontal,
chartSpace.Constants.chGradientVariantStart,
chartSpace.Constants.chGradientFire);


// Set the font size for the chart values.
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Size = 6;

// Get the start and end dates from the X axis.
var startDate = chart.Axes(0).CategoryLabels.Item(0).Caption;
var endDate = chart.Axes(0).CategoryLabels.Item(chart.Axes(0).CategoryLabels.ItemCount-1).Caption;

// Set the caption below the chart.
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption =
"This chart shows the hits by day from "
+ startDate + " to " + endDate + ".";
chartSpace.ChartSpaceTitle.Font.Size = 10;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Set the style and caption for the Y axis.
chart.Axes(0).Font.Size = 8;
chart.Axes(0).HasTitle = true;
chart.Axes(0).Title.Caption = "Dates";
chart.Axes(0).Title.Font.Size = 9;

// Set the style and caption for the X axis.
chart.Axes(1).Font.Size = 7;
chart.Axes(1).HasTitle = true;
chart.Axes(1).Title.Caption = "Hits";
chart.Axes(1).Title.Font.Size = 9;

When you run the VBScript, this will create the following chart:

There are three parameters for the SetPresetGradient method to look at:

ParameterDescription
GradientStyle This is a value from the ChartGradientStyleEnum enumeration, which specifies how the gradient will be displayed. For example: horizontally, vertically, diagonally, etc.
GradientVariant This is a value from the ChartGradientVariantEnum enumeration, which specifies which direction the gradient will be displayed. For example: lighter to darker, from the inside to the outside, etc.
GradientPreset This is a value from the ChartPresetGradientTypeEnum enumeration, which specifies the gradient preset palette.

There are several of preset gradients in the ChartPresetGradientTypeEnum enumeration, and a little experimentation will yield the best results.

Using 3-D Area Charts

For one last sample, I'd like to show you what gradients can do for your 3-D area charts. To do so, we first need to make a couple of small changes the VBScript that will create the chart:

Option Explicit

' Declare the variables.
Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

' Create the Log Parser objects.
Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

' Define the SQL query.
strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO _Part2.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

' Specify the chart options.
objOutputChartFormat.groupSize = "1024x768"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area3D"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"
objOutputChartFormat.config = "Part2.js"

' Execute the SQL statement to create the chart.
objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat

Next, we need to update the JavaScript for the chart configuration script to work with the new VBScript; for the most part, I'm just updating font sizes and chart colors:

// Set the title above the chart.
chart.HasTitle = true;
chart.Title.Caption = "Hits by Day"

// Clear the caption for the chart series.
chart.SeriesCollection(0).Caption = "";

// Set the border style for the chart.
chartSpace.Border.Color = "#000000";
chartSpace.Border.Weight = 2;

// Change the background color for the plot area.
chart.PlotArea.Interior.Color = "#FFFFCC";

// Specify the chart gradient styles.
chart.SeriesCollection(0).Interior.SetTwoColorGradient(
chartSpace.Constants.chGradientHorizontal,
chartSpace.Constants.chGradientVariantEnd,
"#00CCFF",
"#FFFFFF");

// Set the font size for the chart values.
chart.SeriesCollection(0).DataLabelsCollection(0).Font.Size = 7;

// Get the start and end dates from the X axis.
var startDate = chart.Axes(0).CategoryLabels.Item(0).Caption;
var endDate = chart.Axes(0).CategoryLabels.Item(chart.Axes(0).CategoryLabels.ItemCount-1).Caption;

// Set the caption below the chart.
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption =
"This chart shows the hits by day from "
+ startDate + " to " + endDate + ".";
chartSpace.ChartSpaceTitle.Font.Size = 10;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Set the style and caption for the Y axis.
chart.Axes(0).Font.Size = 10;
chart.Axes(0).HasTitle = true;
chart.Axes(0).Title.Caption = "Dates";
chart.Axes(0).Title.Font.Size = 11;

// Set the style and caption for the X axis.
chart.Axes(1).Font.Size = 9;
chart.Axes(1).HasTitle = true;
chart.Axes(1).Title.Caption = "Hits";
chart.Axes(1).Title.Font.Size = 11;

When you run the VBScript, this will create the following chart:

Summary

In this blog post, I've written a lot of code samples in order to show you four different ways to set gradients for your Log Parser area charts. In future posts, I'll show you how to do some more cool things with some other types of charts.

Advanced Log Parser Charts Part 1 - Working With Configuration Scripts

I recently had a situation where I wanted to customize the chart output from Log Parser, and after a bunch of research I eventually arrived at the conclusion that configuration scripts to create customized charts are probably the least-documented feature of Log Parser. After a lot of experimentation, (and a bit of frustration), I finally managed to achieve the results that I wanted. With that in mind, I thought that it would make a great blog series if I documented some of the settings that I used.

Log Parser and Chart Configuration Scripts

When you look in the Log Parser help file, it makes mention of using configuration scripts to customize charts, and it provides the following small JavaScript sample:

// Add a caption
chartSpace.HasChartSpaceTitle = true;
chartSpace.ChartSpaceTitle.Caption = "Generated by Log Parser 2.2";
chartSpace.ChartSpaceTitle.Font.Size = 6;
chartSpace.ChartSpaceTitle.Position = chartSpace.Constants.chTitlePositionBottom;

// Change the background color
chart.PlotArea.Interior.Color = chartSpace.Constants.chColorNone;

Unfortunately, this sample isn't very useful, although I found dozens of forum posts that quote this sample as a way to do things - but it's the only sample that most people cite. The Log Parser help file mentions looking at the MSDN ChartSpace Object Model documentation, but that documentation is only slightly more useful. These two references are what led me to my earlier conclusion that chart configuration scripts are not well-documented, and especially when you are trying to do something with Log Parser.

What I found to be particularly helpful was to use the Log Parser COM interface and write scripts by using Adersoft's VbsEdit and JsEdit. In case you haven't used either of those applications, they are great IDEs for writing scripts; they both give you a great debugging environment, and they have a great object browser that I used to discover what options were available to me. In the end, these two editors made it possible to create the chart configuration scripts that I will discuss in this blog series.

By the way, chart configuration scripts can be written in VBScript or JavaScript, but for this blog I will use VBScript for the Log Parser COM samples and JavaScript for the configuration script samples. I didn't have to do it that way, but it seemed like a good idea to help differentiate between the samples.

Using COM versus the Command-Line

For the samples in this blog series, I will use Log Parser's COM interface and VBScript to create my charts, but this is not necessary; everything that I am documenting can be done from the command-line version of Log parser, and I'll give you some quick examples to see the differences.

The following examples generate some simple area charts that plot the total number of hits by day, and both examples do exactly the same thing:

Command-Line:

logparser.exe "SELECT Date, COUNT(*) AS Hits INTO HitsByDay.gif FROM *.log GROUP BY Date ORDER BY Date" -i:W3C -fileType:GIF -groupSize:800x600 -chartType:Area -categories:ON -values:ON -legend:OFF

COM Interface:
Option Explicit

Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO HitsByDay.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

objOutputChartFormat.groupSize = "800x600"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"

objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat
Ugly Charts

Using some of the log files from one of my websites, the above samples created the following basic chart:

Taking a look at this chart makes it easy to see why you would want to customize your output; that light blue is pretty awful, and those values are pretty hard to read.

Specifying Configuration Scripts

If you remember the incredibly basic configuration script from earlier, you only need to add one parameter to each example in order to specify the configuration script:

Command-Line:

logparser.exe "SELECT Date, COUNT(*) AS Hits INTO HitsByDay.gif FROM *.log GROUP BY Date ORDER BY Date" -i:W3C -fileType:GIF -groupSize:800x600 -chartType:Area -categories:ON -values:ON -legend:OFF -config:HitsByDay.js

COM Interface:
Option Explicit

Dim objLogQuery, strSQL
Dim objInputW3CFormat, objOutputChartFormat

Set objLogQuery = WScript.CreateObject("MSUtil.LogQuery")
Set objInputW3CFormat = WScript.CreateObject("MSUtil.LogQuery.W3CInputFormat")
Set objOutputChartFormat = WScript.CreateObject("MSUtil.LogQuery.ChartOutputFormat")

strSQL = "SELECT Date, COUNT(*) AS Hits " & _
" INTO HitsByDay.gif " & _
" FROM *.log " & _
" GROUP BY Date " & _
" ORDER BY Date"

objOutputChartFormat.groupSize = "800x600"
objOutputChartFormat.fileType = "GIF"
objOutputChartFormat.chartType = "Area"
objOutputChartFormat.categories = "ON"
objOutputChartFormat.values = "ON"
objOutputChartFormat.legend = "OFF"
objOutputChartFormat.config = "HitsByDay.js"

objLogQuery.ExecuteBatch strSQL, objInputW3CFormat, objOutputChartFormat
Simple Output

Taking a look at the resulting chart, you can see why I mentioned earlier that the configuration script wasn't very useful; all it does is add a centered title to the bottom of the chart:

Yup - that's a pretty useless sample configuration script for chart customization.

Next...

In my subsequent posts, I'll show how to make this chart (and several other types of charts) look a lot better.

Storing IIS 7.5 WebDAV Properties in NTFS Alternate Data Streams

Two months ago Microsoft published an update for the WebDAV module that shipped with IIS 7.5 in Windows 7 and Windows Server 2008 R2, and this update is documented in the Microsoft Knowledge Base article ID 2593591:

FIX: A hotfix is available that enables WebDAV to store the properties of file resources by using NTFS alternate data streams in IIS 7.5

This update enables administrators to configure the IIS 7.5 WebDAV module to store WebDAV-based properties in NTFS alternate data streams instead of properties.dav files. By way of explanation, WebDAV has two HTTP methods - PROPFIND and PROPPATCH - which enable WebDAV clients to store custom properties on a WebDAV server. These properties may contain anything that makes sense to the WebDAV client. For example, if you were creating a WebDAV client that stored Microsoft Office documents on a WebDAV server, you could store metadata in WebDAV properties for each document, like the author's name, document abstract, etc.

By default, the IIS 7.5 WebDAV module stores properties in system files in each folder of a website that are called properties.dav. These files are essentially text-based INI files that contain the encoded WebDAV properties for the various files in each folder. In contrast, the WebDAV functionality in IIS 6 had used NTFS alternate data streams to store WebDAV properties, which are described in the following Microsoft TechNet article:

The NTFS File System

After we shipped IIS 6, we received a lot of complaints from customers who were losing their WebDAV properties when they were copying their website files between NTFS and FAT file systems. This was expected behavior - NTFS alternate data streams will be removed when you copy files from NTFS to FAT. To remedy this situation, in IIS 7.0 we decided to switch to using INI-based functionality in order to prevent losing custom WebDAV properties when files are copied between disparate file systems.

When we were designing IIS 7.5, we wanted to add optional support for storing WebDAV properties in NTFS alternate data streams, and we wanted to do so because NTFS alternate data streams might perform faster when you are working with larger websites; however, we ran out of time to implement that functionality before we shipped Windows 7 and Windows Server 2008 R2. That being said, we still wanted to implement the feature, and the update that I listed at the beginning of this blog contains the functionality that is required to enable storing WebDAV properties in NTFS alternate data streams.

Enabling Alternate Data Streams for WebDAV Properties

The above information is good news for anyone who is storing large quantities of WebDAV properties, so your next logical question might be: "How do I enable NTFS alternate data streams for WebDAV properties ?"

Actually, it's really simple. In the KB article that I listed in the beginning of this blog, I documented two methods that show you how to enable storing WebDAV properties in NTFS alternate data streams:

  1. By modifying your applicationHost.config file
  2. By using AppCmd.exe

For the sake of completeness, I will repost some of the information here. ;-)

Method #1: Modifying your applicationHost.config file

You can enable storing WebDAV properties in alternate data streams for the simple property provider by adding a "useAlternateDataStreams" attribute to the property provider’s registration settings in your applicationHost.config file, which is highlighted in the following global configuration snippet:

<webdav>
  <globalSettings>
    <propertyStores>
      <add name="webdav_simple_prop"
        image="%windir%\system32\inetsrv\webdav_simple_prop.dll"
        image32="%windir%\syswow64\inetsrv\webdav_simple_prop.dll"
        useAlternateDataStreams="true" />
    </propertyStores>
    <lockStores>
      <add name="webdav_simple_lock"
        image="%windir%\system32\inetsrv\webdav_simple_lock.dll"
        image32="%windir%\syswow64\inetsrv\webdav_simple_lock.dll" />
    </lockStores>
  </globalSettings>
  <authoring>
    <locks enabled="true" lockStore="webdav_simple_lock" />
    <properties>
      <clear />
      <add xmlNamespace="*" propertyStore="webdav_simple_prop" />
    </properties>
  </authoring>
  <authoringRules />
</webdav>

Once you have enabled the feature, you have to restart IIS in order for it to take effect.

Method #2: Using AppCmd.exe

I wrote the following batch file for the KB article, which uses AppCmd.exe to enable the NTFS alternate data streams functionality, and it automatically restarts IIS for you:

pushd "%SystemRoot%\System32\Inetsrv"

iisreset /stop

appcmd.exe set config -section:system.webServer/webdav/globalSettings -propertyStores.[name='webdav_simple_prop'].useAlternateDataStreams:true /commit:apphost

iisreset /start

popd

Migrating IIS 7 WebDAV Properties into Alternate Data Streams

Once you've enabled storing WebDAV properties in alternate data streams, you are presented with a new challenge: "How do I migrate my existing WebDAV properties?"

Here's the situation, once you have enabled the alternate data streams feature, the WebDAV property provider is going to ignore any properties that have already been set in properties.dav files. With this in mind, I wrote a script that will migrate all of the WebDAV properties from all of the properties.dav files in a website into their corresponding per-file NTFS alternate data streams.

To use the following script, you will need to update the folder path in the third line of the script with the path to your website. Once you have done that, you can run the script to migrate your existing WebDAV properties.

NOTE: You need to run this script as an administrator!

Option Explicit

Dim arrFolderTree, intFolderCount

arrFolderTree = BuildFolderTree("C:\inetpub\wwwroot")

For intFolderCount = 1 To UBound(arrFolderTree)
  MigratePropertiesToADS arrFolderTree(intFolderCount)
Next

Sub MigratePropertiesToADS(strFolderPath)
  On Error Resume Next
  
  ' Declare all our variables
  Dim objTempFSO, objTempFolder
  Dim objTempPropertiesFile, objTempAlternateDataStream
  Dim strTempLine, strTempObjectName, blnTempOpenStream
  Const strTempPropertiesDAV = "\properties.dav"
  Const strTempAlternateDataStream = ":properties.dav:$DATA"

  ' Create a file system object.
  Set objTempFSO = WScript.CreateObject("Scripting.FileSystemObject")

  ' Flag the function as having a closed output stream.
  blnTempOpenStream = False

  ' Retrieve a folder object for the path.
  Set objTempFolder = objTempFSO.GetFolder(strFolderPath)

  ' Check for a properties.dav file in the current folder.
  If objTempFSO.FileExists(objTempFolder.Path & strTempPropertiesDAV) Then
    ' Open the properties.dav file for the current folder.
    Set objTempPropertiesFile = objTempFSO.OpenTextFile(objTempFolder.Path & _
      strTempPropertiesDAV,1,False,-1)
    ' Loop through the properties.dav file.
    Do While Not objTempPropertiesFile.AtEndOfStream
      ' Retrieve a line from the properties.dav file.
      strTempLine = Trim(objTempPropertiesFile.ReadLine)
      ' Check if it's a section heading.
      If Left(strTempLine,1) = "[" And Right(strTempLine,1) = "]" Then
        ' Parse the name of the object (file/folder).
        strTempObjectName = Replace(Trim(Mid(strTempLine,2,Len(strTempLine)-2)),"/","\")
        ' Strip off a backslash from the parent folder.
        If Len(strTempObjectName) = 1 Then strTempObjectName = ""
        ' Check to see if the file/folder exists.
        If objTempFSO.FileExists(objTempFolder.Path & _
             strTempObjectName) Or objTempFSO.FolderExists(objTempFolder.Path & _
             strTempObjectName) Then
          ' Create a file object for the alternate data stream.
          Set objTempAlternateDataStream = objTempFSO.CreateTextFile(objTempFolder.Path & _
             strTempObjectName & _
             strTempAlternateDataStream,True,-1)

I have a couple final notes for you to consider:

  • Enabling NTFS alternate data streams is a global WebDAV setting; you cannot do this on a per-site basis.
  • As with IIS 6, once you enable storing WebDAV properties in NTFS alternate data streams, you will lose your WebDAV properties if you copy your files between NTFS and FAT file systems.

How to create an HTML Application to configure your WebDAV Redirector settings

I've mentioned in previous blog posts that I use the Windows WebDAV Redirector a lot. (And believe me, I use it a lot.) Having said that, there are a lot of registry settings that control how the Windows WebDAV Redirector operates, and I tend to tweak those settings fairly often.

I documented all of those registry settings in my Using the WebDAV Redirector walkthrough, but unfortunately there isn't a built-in interface for managing the settings. With that in mind, I decided to write my own user interface.

I knew that it would be pretty simple to create a basic Windows Form application that does everything, but my trouble is that I would want to share the code in a blog, and the steps create a Windows application are probably more than I would want to write in such a short space. So I decided to reach into my scripting past and create an HTML Application for Windows that configures all of the Windows WebDAV Redirector settings.

It should be noted, like everything else these days, that this code is provided as-is. ;-]

Using the HTML Application

When you run the application, it will present you with the following user interface, which allows you to configure most of the useful Windows WebDAV Redirector settings:

Creating the HTML Application

To create this HTML Application, save the following HTMLA code as "WebDAV Redirector Settings.hta" to your computer, and then double-click its icon to run the application.

<html>

Additional Notes

You will need to run this HTML Application as an administrator in order to save the settings and restart the Windows WebDAV Redirector. (Which is listed as the "WebClient" service in your Administrative Tools.)

This HTML Application performs basic validation for the numeric fields, and it prevents you from exiting the application when you have unsaved changes, but apart from that there's not much functionality other than setting and retrieving the registry values. How else can you get away with posting an application in a blog with only 500 lines of code and no compilation required? ;-]

How to create an HTML Application to configure your WebDAV Redirector settings

I've mentioned in previous blog posts that I use the Windows WebDAV Redirector a lot. (And believe me, I use it a lot.) Having said that, there are a lot of registry settings that control how the Windows WebDAV Redirector operates, and I tend to tweak those settings fairly often.

I documented all of those registry settings in my Using the WebDAV Redirector walkthrough, but unfortunately there isn't a built-in interface for managing the settings. With that in mind, I decided to write my own user interface.

I knew that it would be pretty simple to create a basic Windows Form application that does everything, but my trouble is that I would want to share the code in a blog, and the steps create a Windows application are probably more than I would want to write in such a short space. So I decided to reach into my scripting past and create an HTML Application for Windows that configures all of the Windows WebDAV Redirector settings.

It should be noted, like everything else these days, that this code is provided as-is. ;-]

Using the HTML Application

When you run the application, it will present you with the following user interface, which allows you to configure most of the useful Windows WebDAV Redirector settings:

Creating the HTML Application

To create this HTML Application, save the following HTMLA code as "WebDAV Redirector Settings.hta" to your computer, and then double-click its icon to run the application.

Additional Notes

You will need to run this HTML Application as an administrator in order to save the settings and restart the Windows WebDAV Redirector. (Which is listed as the "WebClient" service in your Administrative Tools.)

This HTML Application performs basic validation for the numeric fields, and it prevents you from exiting the application when you have unsaved changes, but apart from that there's not much functionality other than setting and retrieving the registry values. How else can you get away with posting an application in a blog with only 500 lines of code and no compilation required? ;-]

Sometimes I Make My Day…

This past weekend I was writing a quick piece of Windows Script Host (WSH) code to clean up some files on one of my servers, and I had populated a Scripting.Dictionary object with a bunch of string data that I was going to write to a log file. Obviously it’s much easier to read through the log file if the data is sorted, but the Scripting.Dictionary object does not have a built-in Sort() method.

With this in mind, I set out to write a sorting function for my script, when I decided that it would might be more efficient to see if someone out in the community had already written such a function. I quickly discovered that someone had – and it turns out, that particular someone was me!

Way back in 1999 I published Microsoft Knowledge Base (KB) article 246067, which was titled "Sorting a Scripting Dictionary Populated with String Data." This KB article contained the following code, which took care of everything for me:

Const dictKey  = 1
Const dictItem = 2

Function SortDictionary(objDict,intSort)
  ' declare our variables
  Dim strDict()
  Dim objKey
  Dim strKey,strItem
  Dim X,Y,Z

  ' get the dictionary count
  Z = objDict.Count

  ' we need more than one item to warrant sorting
  If Z > 1 Then
    ' create an array to store dictionary information
    ReDim strDict(Z,2)
    X = 0
    ' populate the string array
    For Each objKey In objDict
        strDict(X,dictKey)  = CStr(objKey)
        strDict(X,dictItem) = CStr(objDict(objKey))
        X = X + 1
    Next

    ' perform a a shell sort of the string array
    For X = 0 to (Z - 2)
      For Y = X to (Z - 1)
        If StrComp(strDict(X,intSort),strDict(Y,intSort),vbTextCompare) > 0 Then
            strKey  = strDict(X,dictKey)
            strItem = strDict(X,dictItem)
            strDict(X,dictKey)  = strDict(Y,dictKey)
            strDict(X,dictItem) = strDict(Y,dictItem)
            strDict(Y,dictKey)  = strKey
            strDict(Y,dictItem) = strItem
        End If
      Next
    Next

    ' erase the contents of the dictionary object
    objDict.RemoveAll

    ' repopulate the dictionary with the sorted information
    For X = 0 to (Z - 1)
      objDict.Add strDict(X,dictKey), strDict(X,dictItem)
    Next

  End If

End Function
