this event is not gettting called as the application is not minimized or maximized using buttons but through window + D .

I get the messages for a normal Windows program, but not for a Dialog. I suspect that is because a Dialog window is a fixed size and therefor does not need to handle the WM_SIZE message. I guess you could create a custom (subclassed) dialog and add it to the WndProc function in there. But it sounds like a lot of work for something that is not really of any great use.

Right! does not seem to be a great choice.

Richard MacCutchan 28-Jun-18 3:06am

Well that's Windows for you.

could you atleast tell me that which event is called whenever you press window + D ?

Richard MacCutchan 2-Jul-18 4:20am

I don't know. You will need to write a test dialog which overloads the WndProc handler, and capture all messages to see which one(s) get sent. Or you could get a copy of Spy++ which shows the messages being passed through the system.
