SendMessage to Worker thread

[Ajay L D]

Is it possible to send a message to a worker thread? I know we could send a message to a UI thread, but is the same possible with a worker thread? Thanks, AJ

Yes. It is possible. Use PostThreadMessage. Hope that helps. Kiran.

I assume by the term "a message" you mean a message such as sent by the functions SendMessage, PostMessage, PostThreadMessage and friends. If so the answer is yes but there is a catch: the receiving thread must be running a message pump and in the case of thread messages it will have to be written accordingly.

Worker threads dont have MessagePump. So I dont think SendMessage,PostMessage or Post ThreadMessage will work. to send messages to worker threads you can try and use events.

Thanks! I also thought, unless you have a message pump in your thread...it is impossible to send any kind of message using the SendMessage call. As you told, we have to use some kind of synchronization objects. Thanks again, AJ

you have to setup message pump in the thread to handle message

hi kiran, you have to setup message pump in the worker thread to process message send thorugh PostThreadMessage!
