Funny you should ask ...<BR>I'm trying to run a series of DOS batch files, checking for success at each step. All I can do so far is launch a batch job, but that's a start, eh?<BR><BR> Set WshShell = CreateObject("WScript.Shell") <BR> WshShell.Run "C:InetPubwwwrootBuildTest.bat a b c d",1,TRUE<BR><BR>The MSDN help will tell you about the valid values for the second RUN parameter - 0 is for the DOS window to be invisible.<BR><BR>Let me know how you go ... I think control returns to the calling ASP on exit of the DOS program ... ???
