                    if u know the name of a window in the process ur going to create, u can get the handle of the window using the FindWindow() function, Once u get the window handle, U can send and receive messages. nave

                        i didn't find any links...But it simple... 1. Use RegisterWindowMessage() to register a type of message. 2. Use FindWindow() to find the Window u wanted. 3. Then send the message as usaaal using the postmessage or sendmessage. 4. Overide the WindowProc funtion of the window to which u send the message. Inside that u can check whether the message is same as as that u send using the post/send message. :cool: nave

                          you have to interprocess communication between them!
