How can I launch more than one application on a Microsoft Terminal Server using a published application?

On the terminal server, create a file in a directory like c:\launchers call it launcher1.vbs 

Dim objShell 
Dim objExec 
Dim strAppExe 
Const MAXIMIZE_WINDOW=3 
Const MINIMIZE_WINDOW=7 

’ List of codes http://www.microsoft.com/technet/scriptcenter/guide/sas_wsh_pkoy.mspx?mfr=true 

Set objShell = Wscript.CreateObject("WScript.Shell") 

’ Run the first app and minimize it. 
objShell.Run "notepad.exe", MINIMIZE_WINDOW 

’ Run the second app 
objShell.Run "mspaint.exe", MINIMIZE_WINDOW 

’ Run the last app in the sequence 
strAppExe = "calc.exe" 
Set objExec = objShell.Exec(strAppExe) 

’ Watch for this LAST app to close and logoff 
Do While objExec.Status = 0 
WScript.Sleep 500 
Loop 

Set objExec = objShell.Exec("logoff") 

Next for the webapp, launch wscript and pass the parameter c:\launchers\launcher1.vbs 

This will launch notepad.exe minimized, mspaint.exe minimized and calc.exe normally. It will wait for calc.exe to close before performing a logoff.
