Question

This is closely related to an earlier question.

In the managed world:

• How do I check if the current thread has messages in its message queue?
• How do I yield to the OS and wait for a message in the current thread (like GetMessage or WaitMessage)?

I am looking for the managed equivalents without PInvoke.

Answer 1

You can use the AddMessageFilter function.

I don’t think there’s a blocking way how to do that without P/Invoke, since it’s beyond intentions of .NET.
