Returning an exit code from an MFC based application
Posted on 2003-11-25
I'm in the process of writing an MFC-based application that runs commands on a remote UNIX server and routes any standard error text back to the Windows client where it is displayed in a pop-up error dialog. I need to be able to pass command line parameters into the client app which are then used to invoke the command on the server. This all works fine.
The problem I've got is that I need to be able to exit the invoking client application with the same exit code as seen on the server. This is because the client app is invoked by a 3rd party SCM tool and it needs to know whether the command succeeded or not. I originally wrote the client as a console application and this was fine - I simply had to call exit() with the relevant exit code. The problem with that approach is that I got a Console Window popping up when the client app was invoked from the 3rd party tool. This looked quite ugly. By rewriting the application as an MFC project then I obviously don't get the Console Window popping up but I can't return an exit code either!
I don't want to use "start" or any similar mechanism to start the client - I just want to run it from the command line (with all its parameters) and have it exit (say when the InitInstance() function finishes) with the appropriate exit code.
I'm using VC++ 6.0
I guess the questions are:
1) Is this even possible with MFC or do I have to use more low-level function calls?
2) Would it be simpler to write a console app and somehow suppress the console window from appearing? if so - how can I do that?
500 points riding on this one!
