Terminate an application

  : What is the best way to terminate an application? I usually just call exit(0); from within my view-class, but sometimes that generates an error message. Suggestions?

  Hmm... I have used exit(1); and haven't got a single error. What does that number in exit argument mean? Has this something to do with this prob?

  I don't think so. You should use exit(0); since that indicates EXIT_SUCCESS. exit(1) indicates EXIT_FAILURE.
  
  I think my problem is that i don't clean up after my application. I have an App-Wizard-generated SDI-application and when I call exit(0); there is an error message that says that a pagefault has occured in MFC42.dll. I have tried using static linking and the problem seems to go away, but that's not a good solution since my programsize increases almost 4 times with static linking. Has anyone experienced similar problems?

  Simply stop using the exit() function. It does work well for console programs, not for GUI ones. I don't use the MFC, but there will surely be a function (maybe named something like "AfxExit", "AfxExitProgram") which correctly ends the program.

  Use PostQuitMessage(0) instead, or close the main window of the MFC application.

  one way to do it is
  
  AfxGetMainWnd()->SendMessage(WM_CLOSE, 0, 0);
