Terminate MFC App in CView::OnInitialUpdate()

[CodeBrain]

If am searching for a way to exit a MFC MDI application if I discover an error in CMyView::OnInitialUpdate(). If I use SendMessage(WM_CLOSE) to the main window, I get some crashes in MFC classes. Using exit(0) seems to be not very good, because of memeory leaks. So what's the best way to end a MFC application during CMyView::OnInitialUpdate()? Thanks in advance.

First iterate through all the open documents, and close them one by one. Then instead of using SendMessage to send WM_CLOSE, use PostMessage. It should work. Acutually the program crashes, When OnActivateFrame( ... ) is invoked with WA_INACTIVE parameter and the 'this' pointer( which has an invalid value ). So use PostMessage.

Use PostMessage instead of SendMessage. SendMessage is a synchronous do it now kind of thing, which will rip the floor from underneath you, while PostMessage will defer it until OnInitialUpdate returns. Steve S

Why not use PostQuitMessage() ? Roger Allen Sonork 100.10016 Were you different as a kid? Did you ever say "Ooohhh, shiny red" even once? - Paul Watson 11-February-2003

PostQuitMessage is another option. But it uses WM_QUIT instead of WM_CLOSE. I thought, since the guy was using WM_CLOSE, lets us point out, where he has went wrong. Actualy the problem was with using SendMessage, and not with WM_CLOSE.
