Hi Neelesh, A CallBack function is called by Operating system. The classic example of a callback function is WndProc() function in "Hello World" sample found in any Win32 Programming book. Regards Abhi Lahare

1. you have two functions : FunctionA and FunctionB. 2. you call FunctionA with a pointer to FunctionB. 3. FunctionA calls FunctionB as part of its processing, usually in a loop. Software | Cleek
