From: Steve Ricketts on 20 Dec 2009 17:43 I need to make a modification to a service written in VB6 that modifies and then executes a .bat file. This runs fine when it's run from the command line, but when I start it as a service, it creates the .bat file but doesn't run it. I'm sure there's some sort of a permissions issue with the account the service is running under but I've tried the local system account as well as the administrator's account and there is no difference. Can someone tell me what I need to do in order to run a .bat file from a service? Thanks, Steve

How about modifying the .bat file to write a line to a text file each time it performs a step, so you can see what kind of progress, if any, is being made? If you're using the Shell command are you watching the returned value? e.g. Dim RetVal RetVal = Shell("(path)\(file).bat", vbWindowState) http://www.codetoad.com/forum/18_23202.asp Mike

What does the batch file do? Are there any commands which prompt the user in any way? If so, I can see how this may not run from a service unless the "allow to interact with desktop" option , or whatever it's called, is enabled. But if the program is writing this batch file, why can't it just perform the same tasks? -- Mike

I was wondering about that too, do you use a batch file for speed, or could you replace it with a VB program?

Too many things could be happening, and not enough information. Try using Shell, and surround the path by double-quotes. Example: sBatchFile = """" & "C:\Program Files\Test\test.bat" & """"" Debug.Print sBatchFile Shell sBatchFile & " /SomeOption", vbHide Whether you use Shell or CreateProcess, the target process runs as the same user as the service. If using CreateProcess, I think you need to run "CMD.EXE /C file.bat", but instead of hard coding "CMD.EXE", use Environ("ComSpec"). |
