Question

How to set environement variable only for a process...

Asked by: EricPelletier

hi experts,

I have a cmd file that set variables and launch an application. When launching a cmd, the cmd stays open until you close the application. I'd like to do the same but using a VBS file so it will set the environement variable only for that session, launch the application and no extra windows will stay open. Is it possible to do that in VBS?
I attached the code of my cmd

Your help is appreciated.

thank you

set Path=C:\syb1200\OCS-12_0\dll;C:\syb1200\OCS-12_0\bin;%PATH%
set SYBASE=C:\syb1200
set SYBASE_OCS=OCS-12_0
set LIB=c:\syb1200\OCS-12_0\lib;c:\syb1200\OCS-12_0\lib
set INCLUDE=c:\syb1200\OCS-12_0\include;c:\syb1200\OCS-12_0\include
C:
cd \
cd C:\Program Files\myapp
myapp.exe
exit

Sure, in VBScript it would look like:  (save as "whatever.vbs" and you should be able to run it)

Set shell = WScript.CreateObject("WScript.Shell")
Set env = shell.Environment("Process")
env("Path") = "C:\syb1200\OCS-12_0\dll;C:\syb1200\OCS-12_0\bin;" & env("PATH")
env("SYBASE") = "C:\syb1200"
env("SYBASE_OCS") = "OCS-12_0"
env("LIB") = "c:\syb1200\OCS-12_0\lib;c:\syb1200\OCS-12_0\lib"
env("INCLUDE") = "c:\syb1200\OCS-12_0\include;c:\syb1200\OCS-12_0\include"
shell.CurrentDirectory = "C:\Program Files\myapp"
shell.Run "myapp.exe"

I did not have time to test 100% but it seems to work fine and it does exactly what I need.
