Software Deployment

The alternative? Use the object without the WScript directive! WScript refers to the Windows Scripting Host script interpreter. The WI engine uses its own interpreter and knows nothing of WSH. This makes testing of scripts external to WI tricky. What I do is set a Boolean according to whether a well-known MSI property is available:Option Explicit

Dim blnIsCustomAction

blnIsCustomAction = False
blnIsDeferred = False

On Error Resume Next
If IsObject(Session) Then
'// We may have arrived here because error-trapping is off
If Err.Number = 0 Then
blnIsCustomAction = True
End If
End If

'// We test a well-known property and, if it's empty, we MUST be in deferred mode, right?
If Len(Session.Property("UpgradeCode")) = 0 Then
blnIsDeferred = True
End If

On Error Goto 0Then, later in the code, we can use those Booleans to branch accordingly:

If blnIsCustomAction Then
If blnIsDeferred Then
strTarget = Split(Session.Property("CustomActionData"), ",")(0)
strGroupName = Split(Session.Property("CustomActionData"), ",")(1)
Else
Select Case LCase(strObjectType)
Case "file"
strTarget = Session.Property("FILETOPERMISSION")
Case "folder"
strTarget = Session.Property("FOLDERTOPERMISSION")
Case Else
strTarget = Session.Property("REGKEYTOPERMISSION")
End Select

strGroupName = Session.Property("APPGROUPNAME")
End If
End IfI use it primarily so that my scripts can be run in Execute Immediate of Execute Deferred with minimal editing in between but by testing the Boolean blnIsCustomAction, you can have different sections called depending on whether the script's being run by WSH or by the WI engine.

First of all read VBScab's brief description in this thread: http://itninja.com/question/faulttree-100362&mpage=1&key=wscript쓄

What are you trying to achieve anyhow? Microsoft state that StdIn is only available when running your script using CScript.exe as its' host....

LOL...I had thought of seeking that post out but decided not to bother. Thanks, Cap'n!
