PumpMessage - How Many 1

[porto99]

When I need to wait for some activity, do I need to place the call to PumpMessage queue into each dialog or just the main dialog of the program.

They may be 10 dialogs, but 2 will need to do lengthly processing.

Many thanks,

Porto.

If these are modal dialogs then they need to process their own messages, which is what the DoModal() function does for you. If your dialogs are modeless then the main message loop will pump messages to them for you. If you want to write your own modal message loop with special processing for a dialog then you can grab some of the code from the MFC source if you have Visual C. Have a look at int CWnd::RunModalLoop(DWORD dwFlags) in wincore.cpp
