hi all
I have a MFC MDI c++ program,
And I want to know is it possible to decide about close one of tabs (sure to close MsgBox) ? something similar to oncancel function in dialogue base program.

and also is there a event to close the entire program on closing one of tabs?

thanks for your guides

What I have tried:

I tried ondestroy function for first case but it was not successful

You can close any view in an MDI frame. And you can also close the entire program. It is just a matter of writing the code that decides what action to take when the user selects a certain option.

You can use the WM_CLOSE message. Use the PostMessage API for it and do all needed operations like saving data and settings before.

You can also use PostQuitMessage.
