Example Code

The following example shows you how to use the VBScript programming language to display the Web service extension restriction list, display the application dependencies, list the available extension files that are installed on the server, and state if ASP is enabled or disabled.

VBScript

Dim aWebSvcExtRestrictionList 
Dim aApplicationDependencies 
Dim aExt 
Dim sExt 
aExt = Array() 
aWebSvcExtRestrictionList = Array() 
aApplicationDependencies = Array() 
Set IIsWebServiceObj = GetObject("IIS://localhost/W3SVC") 

' Store original value: 
aWebSvcExtRestrictionList = IIsWebServiceObj.WebSvcExtRestrictionList 

WScript.Echo 
WScript.Echo "WebSvcExtRestrictionList property:" 
' For each extension record, 
For Each i in aWebSvcExtRestrictionList 
  WScript.Echo(i) 
Next 

' Store original value: 
aApplicationDependencies = IIsWebServiceObj.Get("ApplicationDependencies") 

WScript.Echo 
WScript.Echo "ApplicationDependencies property:" 
' For each extension record, 
For ValueIndex = 0 To UBound(IIsWebServiceObj.ApplicationDependencies) 
  WScript.Echo IIsWebServiceObj.Get("ApplicationDependencies")(ValueIndex) 
Next 

WScript.Echo 
' For each extension record, 
For ValueIndex = 0 To UBound(IIsWebServiceObj.WebSvcExtRestrictionList) 

  sExt = IIsWebServiceObj.Get("WebSvcExtRestrictionList")(ValueIndex) 

  If ( 0 < (InStr(sExt, "asp.dll")) ) Then 
If ("0" = Left(sExt, 1)) Then  
WScript.Echo "ASP is disabled" 
Elseif ("1" = Left(sExt, 1)) Then  
WScript.Echo "ASP is enabled" 
Else  
WScript.Echo "ASP is set to an unexpected value" 
End If 
  End If 
Next 

WScript.Echo 
WScript.Echo "ListExtensionFiles method:" 
aExt = IIsWebServiceObj.ListExtensionFiles 
For ValueIndex = 0 To UBound(aExt) 
  WScript.Echo aExt(ValueIndex) 
Next
