Hi all, Thanks for your response for the previous question. All the ideas were excellent. I crossed that problem, but caught in a bit tougher one, I want to set env. variables before kicking off a build. Here is the one which we use in batch file. call setenv c:\NTDDK checked I tried to call a batch file to set the env. variables, but its not working. All ideas would be apperciated. Thanks again, Kumar _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
