VBScript and PSExec - vbscript

Question

Hi I m having problems reading the output provided by WScript.Shell and PSExec. My goal is to be able to read what PSExec.exe returns as text so I can perform some validation with InStr.
The Code is similar to this:
Const WshFinished = 1
Const WshFailed = 2
Dim cmdLine, strComputer
strComputer = "\\SomeComputer"
cmdLine = "psexec " & strComputer & " cmd /C " & """RD " & """%PROGRAMFILES%\APPFOLDER""" & " /S /Q | RD " & """%PROGRAMFILES%\COMMON FILES\APPFOLDER""" & " /S /Q | RD " & """%SYSTEMROOT%\temp\APPFOLDER""" & " /S /Q"""
Set WSH = WScript.CreateObject("WScript.Shell")
WSH.Exec(cmdLine)
Do While WSH.Status = 0
WScript.Sleep 100
Loop
Select Case WSH.Status
Case WshFinished
strOutput = WSH.StdOut.ReadAll
Case WshFailed
strOutput = WSH.StdErr.ReadAll
End Select
Wscript.Echo strOutput
If (InStr(strOutput, "validation text") > 0) Then
'Do Stuff
End IF
The Problem is that strOutput variable comes always empty and I can't perform text validation using - If (InStr(strOutput, "validation text") > 0)
Any Ideas?

Have you considered sending the output from psexec to an output file and then reading the output file from your vbscript?
psexec \\remotemachine command.exe >C:\temp\output.txt 2>&1
will execute command.exe and send output from stdOut and stdErr directly into the file output.txt in C:\temp. You can amend this for your own command.
