Console Application - Exit Code

[Mythran]

What is the correct way to set the exit code from within a console
application? Currently we do:

Public Function Main() As Integer
...
Environment.Exi tCode = ...
Return Environment.Exi tCode
End Function

Should we use Environment.Exi tCode And/Or return the exit code?

Thanks,
Mythran

You do not need to (and IMO should not) set 'Environment.Ex itCode' if you
return the exit code in the 'Main' function and vice versa.

After performing some tests, I found that setting Environment.Exi tCode does
nothing when Main is defined as a function (and hence, returns a value). If
it is defined as a sub, setting ExitCode sets the exit code. So yes, you
are correct :)

Note that VS.NET 2003 (and maybe VS 2005) didn't show the correct return
value when running the project from within the IDE.

I didn't test running it in the IDE. I had a javascript that ran it and
display the results of the Exec or Run (whichever one it was) function :)
