How can I set the good old DOS errorlevel in Visual
Basic 5.0 when the program exists? I have an existing
application (that I can't change) but can call a VB program, and uses the errorlevel for testing.

You know, you're really in trouble on this one, because you have to communicate between two separate processes and two separate address spaces - you're not in Kansas anymore, Toto!

Here's what I'd do: Modify your VB app to write an error level in a file.  Write another DOS App that shells your VB app, keeps checking for the file, reads the file, and returns a DOS errorlevel to your old DOS app.  Since you run both the old DOS app and the new sheller/errorlevel returner in the same DOS box, they can pass errorlevels between them.  Hey, you can even use a DOS batch process in your DOS box!

If you need any help with this, I have already coded the same thing, once I realized I wasn't in Kansas anymore!

You don't have to bother with any flag files.  Here's how you set the errorlevel from a VB program.

Private Declare Sub ExitProcess Lib "kernel32" (ByVal uExitCode As Long)

public sub main()
    call ExitProcess(_put_your_error_code_here)
end sub
