setting exit code of VB appHello,
My windows app developed in VB has a command line mode. So I expect that other applications will call my app using a shell approach. In the case of command line syntax errors, I want to exit with code that indicates that nature of the error. Is there a way to control the "exit code" the VB application "returns" when it terminates? Perhaps I must make a Win API call? I have perused the VB help files but have not found anything pertinent. tia, MBB MB Blackburn wrote:

In short, I'd recommend you only call it from a native EXE, not in the IDE or from pcode, and make sure it's the *last* thing you (intended to) do in the app. "Karl E.

IMHO the *last* thing a VB app does is MDIForm_Terminate. so i will calling ExitProcess there...unless advised to do otherwise. thanks again, MBB MB Blackburn wrote:

You could be right, in your specific case, but every app is different. (This is getting way non-standard at this point, of course...) "Karl E.

Err.Number: 403 Err.Description: MDI forms cannot be shown modally I would vote against the practice of showing the app main form in sub main modally because it prevents showing other forms modelessly.

Just doesn't seem right. |
