How to shutdown my app gracefully at CMainFrame Initialization

[sdancer75]

Maybe it sounds stupid, but how can i shutdown my app gracefully at CMainFrame Initialization ? I just want to do some system checks and if they fail, then immediately terminate the app before any window is created. Any known methods like PostQuitMessage(0), PostMessage or OnClose etc fails because mainframe window is not created yet. Where to use exit code ? PS: I dont want to use the InitInstance from my App. Regards,

PostQuitMessage definitely works when called from the constructor of CMainFrame. You can check the exit code using the function GetExitCodeProcess. This can be used when invoking the application using the CreateProcess API, where it first waits for the program to terminate using the WaitForSingleObject function. Otherwise you can get the exit code by checking the ERRORLEVEL variable when run from the command prompt or a batch file. Here is more information on this - ERRORLEVEL is not %ERRORLEVEL%[^]

Thanks for the reply. Yes indeed it works but since i am using codejock's library i get assertion errors and the app is not closing as it would expected but it stays alive doing nothing (no mouse or keyboard response). Regards,
