Message sent by the 'X' button in the title bar? (MFC C++)

[huckfinn19]

Hi, I need to execute some code before the the window gets destroyed in my MFC app when someone clicks the 'X' button on the top right corner...

How is it that I can intercept the message, or what function should I write my code in to make it execute BEFORE the window is destroyed?

I'm using a SDI type MFC Application...

Thanks

Simon

Since we are talking SDI (applicable on MDI as well) you could override the document's DeleteContents method, and perform clean up there (that's what it's for).

It will be called for whatever closing reason (ie not only the X button, but Alt+F4 etc. as well).

Try over-riding the response to the WM_CLOSE message. This message is sent to the window before it is closed. In your over-ride you can intercept the messeage and do what ever you would like.

Hope this helps you.
