Andy Coo #3 / 6	Can VB return exit code on program termination as exit(X) in C Interesting.... I think I will try this. I based my (perhaps rash) response on the following snippet from chapter 11 of {filter} Visual Basic: "Visual Basic itself returns an exit code when launched from the command line, but it doesnt provide any means for you to set an exit code in your own programs. (If youre thinking you could call the ExitProcess API yourself, forget it. I tried that, but the exit code you set doesnt show up on the outside.)" -Andy.

Bruno Pari #4 / 6	Can VB return exit code on program termination as exit(X) in C < Use ExitProces API. But, do all your cleanup before using it. Unload Me ExitProcess 2 If you try this in VB IDE, it will also close your VB, without any warning. Bruno Paris Ameba to reply via email, remove nospam_

You must be VERY careful to free up all objects/etc before calling it because your app will end immediately and not go through normal termination/cleanup routines. If you call your app from a bat file you have to use the START /WAIT command because otherwise the app runs in parallel with the dos environment and that eliminates the chance to get the code. In general I prefer to have the VB app create a file and record the termination info if needed but there are cases where the exit code is the best way.

Ro #6 / 6	Can VB return exit code on program termination as exit(X) in C Thanks for all the answers. Back to DOS, can you remind how to force the batch file to wait until the exe is done and not to permit it to run in parallel? Quote: >>Interesting.... I think I will try this.
