Cleaning Up Your Windows System When QuickTime Has Screwed Up Your Media Settings

So here's the deal: I don't use anything from Apple. I have no iPod, no iPhone, no Mac, etc. I buy all of my MP3s through Xbox Music and Amazon. :-] Because of this, I have had no real need to install iTunes or QuickTime in years.

But unfortunately it seemed that I had to install either iTunes or QuickTime at one time or other, mainly because some of my digital cameras recorded video in QuickTime *.MOV format. But over the years I learned to detest both iTunes and QuickTime because of the undesirable ways in which they modified my system; both iTunes and QuickTime would remap all of media settings to open in their @#$% player, which I didn't really want in the first place.

Now that Windows supports the *.MOV format natively, and I can easily convert *.MOV files into something infinitely more useful and universal like *.MP4 format, I really never see the need for installing either iTunes or QuickTime.

However, just the other day I installed a new video editor (which shall remain nameless) and it quietly installed QuickTime on my system. I presume that this was to make it easier to import files in *.MOV format into the video editor, but I was pretty upset when I discovered that QuickTime had been installed. What's more, I was angry when I discovered that QuickTime had once again messed up all of my media settings.

In all of this misery is one saving grace: QuickTime has the decency to preserve your original settings. I am assuming that the backups are for when you uninstall QuickTime and attempt to reclaim your system from being hijacked by Apple, but just the same - that little nicety allowed me to fix my system with a little bit of scripting.

So without further introduction - first the script, and then the explanation:

Const HKEY_CLASSES_ROOT = &H80000000
Const strQuickTimeBAK = "QuickTime.bak"

Set objRegistry = GetObject("winmgmts:" & _
  "{impersonationLevel=impersonate}" & _
  "!\\.\root\default:StdRegProv")
 
objRegistry.EnumKey HKEY_CLASSES_ROOT, "", arrSubKeys

For Each objSubkey in arrSubKeys
  If Len(objSubkey)>2 Then
    If Left(objSubkey,1)="." Then
      objRegistry.EnumValues HKEY_CLASSES_ROOT, _
        objSubkey, arrEntryNames, arrValueTypes
      If IsArray(arrEntryNames) Then
        For i = 0 To UBound(arrEntryNames)
          If StrComp(arrEntryNames(i), strQuickTimeBAK, vbTextCompare)=0 Then
            intReturnValue = objRegistry.GetStringValue( _
              HKEY_CLASSES_ROOT, objSubkey, strQuickTimeBAK, strEntryValue)
            If intReturnValue = 0 Then
              intReturnValue = objRegistry.SetStringValue( _
                HKEY_CLASSES_ROOT, objSubkey, "", strEntryValue)
            End If
          End If
        Next
      End If
    End If
  End If
Next

Here's what this script does: first the script enumerates all of the keys under HKEY_CLASSES_ROOT and looks for file extension mappings, then it looks for mappings which have been modified and backed up by QuickTime. When it locates file extensions which have been modified, it copies the value which was backed up into the default location where it belongs.

All-in-all, it's a pretty straight-forward script, but it sucks that I had to write it.

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#

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample
{
private static void Main()
{
using (ServerManager serverManager = new ServerManager())
{
Configuration config = serverManager.GetApplicationHostConfiguration();
// Retrieve the sites collection.
ConfigurationSection sitesSection = config.GetSection("system.applicationHost/sites");
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)
{
object o = element.GetAttributeValue(keyValues[i]);
string value = null;
if (o != null)
{
value = o.ToString();
}
if (!String.Equals(value, keyValues[i + 1], StringComparison.OrdinalIgnoreCase))

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.

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

Sometimes I make my day. ;-]

Creating XML Reports for FSRM Quota Usage

I had a great question in follow up to the "Secure, Simplified Web Publishing using Microsoft Internet Information Services 7.0" webcast that I delivered the other day, "How you can you programmatically access the quota usage information from the File Server Resource Manager (FSRM)?"

First of all, there is a native API for writing code to access FSRM data detailed at the following URL:

http://msdn2.microsoft.com/en-us/library/bb625489.aspx

That's a bit of overkill if you're just looking to script something.

There is a WMI interface as well, but it’s only for FSRM events.

So that leaves you with a pair of command-line tools that you can script in order to list your quota usage information:

  • storrept.exe - Used to manage storage reports
  • dirquota.exe - Used to manage quota usage

Right out of the box the first command-line tool, storrept.exe, can generate a detailed XML report using a user-definable scope. To see this in action, take the following example syntax and modify the scope parameter to your desired paths:

storrept.exe reports generate /Report:QuotaUsage /Format:XML /Scope:"C:\"

 You can also specify multiple paths in your scope using a pipe-delimited format like:

/Scope:"C:\Inetpub|D:\Inetpub"

When the command has finished, it will tell you the path to your report like the following example:

Storage reports generated successfully in "C:\StorageReports\Interactive".

The XML-based information in the report can then be consumed with whatever method you usually use to parse XML. It should be noted that storrept.exe also supports the following formats: CSV, DHTML, HTML, and TXT.

This XML might be okay for most applications, but for some reason I wanted to customize the information that I received, so I experimented with the second command-line tool, dirquota.exe, to get the result that I was looking for.

First of all, using dirquota.exe quota list returns information in the following format:

Quotas on machine SERVER: Quota Path: C:\inetpub\ftproot Source Template: 100 MB Limit (Matches template) Quota Status: Enabled Limit: 100.00 MB (Hard) Used: 1.00 KB (0%) Available: 100.00 MB Peak Usage: 1.00 KB (10/25/2007 2:15 PM) Thresholds: Warning ( 85%): E-mail Warning ( 95%): E-mail, Event Log Limit (100%): E-mail, Event Log

This information is formatted nicely and is therefore easily parsed, so I wrote the following batch file called "dirquota.cmd" to start things off:

@echo off echo Processing the report... dirquota.exe quota list > dirquota.txt cscript.exe //nologo dirquota.vbs

Next, I wrote the following vbscript application called "dirquota.vbs" to parse the output into some easily-usable XML code:

Option Explicit

Dim objFSO, objFile1, objFile2
Dim strLine, strArray(2)
Dim blnQuota,blnThreshold

' create objects
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile1 = objFSO.OpenTextFile("dirquota.txt")
Set objFile2 = objFSO.CreateTextFile("dirquota.xml")

' start the XML output file
objFile2.WriteLine "<?xml version=""1.0""?>"
objFile2.WriteLine "<Quotas>"

' set the runtime statuses to off
blnQuota = False
blnThreshold = False

' loop through the text file
Do While Not objFile1.AtEndOfStream

  ' get a line from the file
  strLine = objFile1.ReadLine

  ' only process lines with a colon character
  If InStr(strLine,":") Then
    ' split the string manually at the colon character
    strArray(1) = Trim(Left(strLine,InStr(strLine,":")-1))
    strArray(2) = Trim(Mid(strLine,InStr(strLine,":")+1))

    ' filter on strings with parentheses
    strLine = strArray(1)
    If InStr(strLine,"(") Then
      strLine = Trim(Left(strLine,InStr(strLine,"(")-1)) & "*"
    End If

    ' process the inidivdual entries
    Select Case UCase(strLine)

      ' a quota path signifies a new record
      Case UCase("Quota Path")

        ' close any open threshold collections
        If blnThreshold = True Then
          objFile2.WriteLine "</Thresholds>"
        End If

        ' close an open quota element
        If blnQuota= True Then
          objFile2.WriteLine "</Quota>"
        End If

        ' signify a new quota element
        objFile2.WriteLine "<Quota>"

        ' output the relelvant information
        objFile2.WriteLine FormatElement(strArray(1),strArray(2))

        ' set the runtime statuses
        blnQuota= True
        blnThreshold = False

      ' these bits of informaiton are parts of a quota
      Case UCase("Source Template"), UCase("Quota Status"), _
          UCase("Limit"), UCase("Used"), _
          UCase("Available"), UCase("Peak Usage")

        ' close any open threshold collections
        If blnThreshold = True Then
          objFile2.WriteLine "</Thresholds>"
        End If

        ' set the runtime status
        blnThreshold = False

        ' output the relelvant information
        objFile2.WriteLine FormatElement(strArray(1),strArray(2))

      ' these bits of informaiton are thresholds
      Case UCase("Warning*"), UCase("Limit*")

        ' open a threshold collection if not already open
        If blnThreshold = False Then
          objFile2.WriteLine "<Thresholds>"
        End If

        ' output the relelvant information
        objFile2.WriteLine FormatElement( _
          Left(strLine,Len(strLine)-1), _
          Replace(Mid(strArray(1), _
          Len(strLine))," ","") & " " & strArray(2))

        ' set the runtime status
        blnThreshold = True

    End Select
  End If
Loop

' close any open threshold collections
If blnThreshold = True Then
  objFile2.WriteLine "</Thresholds>"
End If

' close an open quota element
If blnQuota= True Then
  objFile2.WriteLine "</Quota>"
End If

' end the XML output file
objFile2.WriteLine "</Quotas>"

objFile1.Close
objFile2.Close
Set objFSO = Nothing

' format data into an XML element
Function FormatElement(tmpName,tmpValue)
  FormatElement = "<" & Replace(tmpName," ","") & _
  ">" & tmpValue & "</" & Replace(tmpName,Chr(32),"") & ">"
End Function

When the batch file and vbscript are run, they will create a file named "dirquota.xml" which will resemble the following example XML:

<?xml version="1.0"?>
<Quotas>
  <Quota>
    <QuotaPath>C:\inetpub\ftproot</QuotaPath>
    <SourceTemplate>100 MB Limit (Matches template)</SourceTemplate>
    <QuotaStatus>Enabled</QuotaStatus>
    <Limit>100.00 MB (Hard)</Limit>
    <Used>1.00 KB (0%)</Used>
    <Available>100.00 MB</Available>
    <PeakUsage>1.00 KB (10/25/2007 2:15 PM)</PeakUsage>
    <Thresholds>
      <Warning>(85%) E-mail</Warning>
      <Warning>(95%) E-mail, Event Log</Warning>
      <Limit>(100%) E-mail, Event Log</Limit>
    </Thresholds>
  </Quota>
</Quotas>

I found the above XML much easier to use than the XML that came from the storrept.exe report, but I'm probably comparing apples to oranges. In any event, I hope this helps someone with questions about FSRM reporting.

Have fun!

Programmatically Enumerating Installations of the FrontPage Server Extensions

I had a great question from a customer the other day: "How do you programmatically enumerate how many web sites on a server have the FrontPage Server Extensions installed?" Of course, that's one of those questions that sounds so simple at first, and then you start to think about how to actually go about it and it gets a little more complicated.

The first thought that came to mind was to just look for all the "W3SVCnnnn" subfolders that are located in the "%ALLUSERSPROFILE%\Application Data\Microsoft\Web Server Extensions\50" folder. (These folders contain the "ROLES.INI" files for each installation.) The trouble with this solution is that some folders and files do not get cleaned up when the server extensions are uninstalled, so you'd get erroneous results.

The next thought that came to mind was to check the registry, because each installation of the server extensions will create a string value and subkey named "Port /LM/W3SVC/nnnn:" under the "[HKLM\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\Ports]" key. Enumerating these keys will give you the list of web sites that have the server extensions or SharePoint installed. The string values that are located under the subkey contain some additional useful information, so I thought that as long as I was enumerating the keys, I might as well enumerate those values.

The resulting script is listed below, and when run it will create a log file that lists all of the web sites that have the server extensions or SharePoint installed on the server that is specified by the "strComputer" constant.

Option Explicit

Const strComputer = "localhost"

Dim objFSO, objFile
Dim objRegistry
Dim strRootKeyPath, strSubKeyPath, strValue
Dim arrRootValueTypes, arrRootValueNames
Dim arrSubValueTypes, arrSubValueNames
Dim intLoopA, intLoopB

Const HKEY_LOCAL_MACHINE = &H80000002
Const REG_SZ = 1

strRootKeyPath = "Software\Microsoft\" & _
  "Shared Tools\Web Server Extensions\Ports"

Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("ServerExtensions.Log")

objFile.WriteLine String(40,"-")
objFile.WriteLine "Report for server: " & UCase(strComputer)
objFile.WriteLine String(40,"-")

Set objRegistry = GetObject(_
  "winmgmts:{impersonationLevel=impersonate}!\\" & _
  strComputer & "\root\default:StdRegProv")
objRegistry.EnumValues HKEY_LOCAL_MACHINE, strRootKeyPath, _
  arrRootValueNames, arrRootValueTypes

For intLoopA = 0 To UBound(arrRootValueTypes)
  If arrRootValueTypes(intLoopA) = REG_SZ Then
    objFile.WriteLine arrRootValueNames(intLoopA)
    strSubKeyPath = strRootKeyPath & _
      "\" & arrRootValueNames(intLoopA)
    objRegistry.EnumValues HKEY_LOCAL_MACHINE, _
      strSubKeyPath, arrSubValueNames, arrSubValueTypes
    For intLoopB = 0 To UBound(arrSubValueTypes)
      If arrSubValueTypes(intLoopB) = REG_SZ Then
        objRegistry.GetStringValue HKEY_LOCAL_MACHINE, _
          strSubKeyPath, arrSubValueNames(intLoopB), strValue
        objFile.WriteLine vbTab & _
          arrSubValueNames(intLoopB) & "=" & strValue
      End If
    Next
    objFile.WriteLine String(40,"-")
  End If
Next

objFile.Close

The script should be fairly easy to understand, and you can customize it to suit your needs. For example, you could change the "strComputer" constant to a string array and loop through an array of servers.

Note: More information about the WMI objects used in the script can be found on the following pages:

Hope this helps!

IIS 6: Creating an Itemized List of Server Bindings

One of my servers has a large number of individual web sites on it, and each of these web sites has several server bindings for different IP addresses, Port Assignments, and Host Headers. As I continue to add more web sites on the server, it becomes increasingly difficult to keep track of all the details using the IIS user interface.

With that in mind, I wrote the following ADSI script which creates a text file that contains an itemized list of all server bindings on a server.

Option Explicit
On Error Resume Next

Dim objBaseNode, objChildNode
Dim objBindings, intBindings
Dim objFSO, objFile, strOutput

Updating several IP addresses using ADSI

(Note: I had originally posted this information on a blog that I kept on http://weblogs.asp.net, but it makes more sense to post it here. [:)] )

Like many web programmers, I host several hobby web sites for fun. (They make a wonderful test bed for new code. ;-] )

And like many computer enthusiasts, I sometimes change my ISP for one reason or another. If you are hosting web sites in a similar situation, I’m sure that you can identify the pain of trying to manually update each old IP address to your new IP address. This situation can be made even more difficult when any number of your web sites are using several host headers because the user interface for the IIS administration tool only lists the first host header. This means that you have to manually view the properties for every site just to locate the IP addresses that you are required to change.

Well, I'm a big believer in replacing any repetitive task with code when it is possible, and a recent change of ISP provided just the right level of inspiration for me to write a simple Active Directory Service Interfaces (ADSI) script that locates IP addresses that have to be changed and updates them to their new values.

To use the example script, I would first suggest that you make a backup copy of your metabase. (The script works fine, but it is always better to have a backup. ;-] ) As soon as your metabase has been backed up, copy the example script into notepad or some other text editor, update the old and new IP addresses that are defined as constants, and then run the script.

Option Explicit
On Error Resume Next
 
Dim objIIS
Dim objSite
Dim varBindings
Dim intBindings
Dim blnChanged
 
Const strOldIP = "10.0.0.1"
Const strNewIP = "192.168.0.1"
 
Set objIIS = GetObject("IIS://LOCALHOST/W3SVC")
 
If (Err <> 0) Then
  WScript.Echo "Error " & Hex(Err.Number) & "(" & _
    Err.Description & ") occurred."
  WScript.Quit
Else
  For Each objSite In objIIS
    blnChanged = False
    If objSite.class = "IIsWebServer" Then
      varBindings = objSite.ServerBindings
      For intBindings = 0 To UBound(varBindings)
        If InStr(varBindings(intBindings),strOldIP) Then
          blnChanged = True
          varBindings(intBindings) = Replace(varBindings(intBindings),strOldIP,strNewIP)
        End If
      Next
    End If
    If blnChanged = True Then
      objSite.ServerBindings = varBindings      
      objSite.Setinfo
    End If
  Next
End If
MsgBox "Finished!"

That’s all for now. Happy coding!

IIS 6: Listing the Host Headers of all Web Sites using ADSI

Note: I originally wrote the following script for a friend, but as every good programmer often does, I kept the script around because I realized that it could come in handy. I've found myself using the script quite often with several of the servers that I manage, so I thought that I'd share it here.

When managing a large web server with dozens of web sites, it's hard to keep track of all the host headers that you have configured in your settings. With that in mind, I wrote the following script that lists the host headers that are assigned on an IIS web server. To use the example script, copy the script into notepad or some other text editor, save it to your server as "HostHeaders.vbs", and then double-click the script to run it. The script will create a text file named "HostHeaders.txt" that contains all the host headers listed by site for your server.

Option Explicit
On Error Resume Next

Dim objBaseNode, objChildNode
Dim objBindings, intBindings
Dim objFSO, objFile, strOutput

' get a base object
Set objBaseNode = GetObject("IIS://LOCALHOST/W3SVC")
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("HostHeaders.txt")

' check if we have an error ...
If (Err.Number <> 0) Then

' ... and output the error.
strOutput = "Error " & Hex(Err.Number) & "("
strOutput = strOutput & Err.Description & ") occurred."

' ... otherwise, continue processing.
Else

' loop through the child nodes
For Each objChildNode In objBaseNode

' is this node for a web site?
If objChildNode.class = "IIsWebServer" Then

' get the name of the node
strOutput = strOutput & "LM/W3SVC/" & _
objChildNode.Name

' get the server comment
strOutput = strOutput & " (" & _
objChildNode.ServerComment & ")" & vbCrLf
' get the bindings
objBindings = objChildNode.ServerBindings
' loop through the bindings
For intBindings = 0 To UBound(objBindings)
strOutput = strOutput & vbTab & _
Chr(34) & objBindings(intBindings) & _
Chr(34) & vbCrLf
Next
End If
' try not to be a CPU hog
Wscript.Sleep 10
Next
End If
objFile.Write strOutput
objFile.Close
Set objBaseNode = Nothing
Set objFSO = Nothing

If you feel adventurous, you could easily modify the script to return the text in a tab-separated or comma-separated format.

Enjoy!
