Determining the source of the WM_CLOSE message.
Hello, people
I am writing an application which is intended to run for very long periods of time. As it is now the application, when minimised, puts an icon in the system tray and happily runs in the background.
I would also like the application to minimise into the system tray when the user clicks in the close button (X button in top right-hand corner) or if they select close from the system menu. Basically I want to be really sure that the user want to close the application and to do this I want them to specifically select Close from the file menu, where they will be prompted to make sure.
I thought that I would implement it in the OnClose handler in the MainFrame class. However, there is no way (well, none that I can find) of determining the WM_CLOSE message's source.
Any help on this would be much appreciated.
Thanks.

Hey, nonubik.
There's nothing particularly wrong with your answer. I just find AndyAinscow's a little more elegant and easier to implement.

Well, if adding member variables is more elegant....

I appreciate that you took time to answer my question, however, I feel that AndyAinscow's solution provides a way of achieving what I want without hassle and, more importantly, quickly.
Again, thanks for taking the time to answer but I will implement AndyAinscow's solution and therefore I think that he deserves the points.

I have no problem with your choice, I just needed some explanation.
