Thanks. Why do we have to use SendMessage() instead of PostMessage() if WM_COPYDATA event is to be posted to another windows.

Actually there is basic difference between PostMessage and SendMessage.. When you Post message using PostMessage... it just post the message in message queue and return immediately... but in case SendMessage i doesn't return till the target program acknowledge it properly... Now i believe you get the point why WM_COPYDATA using SendMessage instead of PostMessage
