In my application I created two procedures namely callbackwnd procedure to handle focus events and mouse procedure to handle mouse click events.when I unhook the two procedure the application will flicker little bit.how to overcome this?
I also like to know which procedure is first to use unhook function ?

You can unhook any procedure at any time.preferably unhook the procedure while closing the window(WM_CLOSE).
The flickering may happened due to unhooking the function twice.
