Hi Rahul,

I believe that the default message queue size is around 10000 messages and can be changed through the registry. It is possible although unlikely that you are exceeding this limit. As Rajesh pointed out you can check for this condition by checking the return value for ERROR_NOT_ENOUGH_QUOTA.

A more likely scenario would be that your thread is interacting with a UI object or modeless dialog and the thread message is being eaten. I would recommend that you check your thread code to make sure that you are not doing anything UI related. Never launch a modal dialog from a worker thread if you expect the thread to be able to recieve thread messages. Instead... have your worker thread post a message back to the main thread and allow that thread to create/manage dialogs.

Best Wishes,
-David Delaune
