Answer / vikram
UI thread and Worker thread can communicate with each other using SendMessage() or PostMessage().SendMessage() returns when the message is used by the Thread. PostMessage Returns immediately. These two method require Window handle of the UI Thread.
One can also use PostThreadMessage(thread id, message).here UI thread id is required.
