The destructor of MFC application [Solved]

[econy]

Hi, in a modal dialog based MFC application, I use addFontResource() function to load font resource in application's InitInstance(). I want to use this font in all life of application. when application ends, then release the font resource. But I can't find the destructor of the modal dialog based MFC application, do I need to write it myself?

It's a dialog based application, can't find

ExitInstance()

Override it, easiest done with the class wizard.

is that means CDialog class has a ExitInstance() member function? inherited from ,maybe a parent class. I will check thhat

It means that your Application object (derived from CWinApp) has an ExitInstance() override.

Since you're adding the font in the application's InitInstance method, it would be properly matched if you release it in ExitInstance[^]. It would also work if done in the destructor of the dialog class, but ExitInstance would be cleaner. The Visual Studio wizard does not normally output the dialog class destructor, but you could write one yourself as you would normally do and it will be called when the dialog class goes out of scope.
