From: Martin DeMello Date: 2004-08-20T03:45:53+09:00 Subject: win32 tip Since it took me many frustrating hours of trial and error to figure out why something that worked perfectly from the dos prompt didn't work when I called it via system() I figured I'd share the gained experience: When using system() to run a batch file, you need to explicitly put in the .bat extension. That is all. martin
