From: Steve Ricketts on 21 Dec 2009 15:10 That's certainly part of it. I don't really want to tie up the service waiting for the program to create the graphics. This particular service can get pretty busy and did didn't seem like a good idea to have it wait while four graphic files were created. sr "Karl E.

Okay, you're starting to make a case for it. <g> -- ..NET: It's About Trust! http://vfred.mvps.org

I've never diddled with services before, to be honest. Are you unable to run *any* batch file, or just not run this particular one? -- ..NET: It's About Trust! http://vfred.mvps.org
