Re: Please Help!!! - CAsyncSocket::OnReceive Not Working for Microsoft UDP Application (msocudp)

Hello. Hope you're weekend went well. I am now trying threading with
UDP sockets. On my first try it seems
the OnReceive() is not getting invoked when sending a packet in a
Please let me know what I might be doing wrong here.
Snippets of my code:
The code can be pretty much thrown away. It seems to have been written
without studying the CAsyncSocket documentation or examples at all. You
must create the socket in the same thread that you want to receive and send
from. There are MFC examples that illustrate this. You must use a UI type
of MFC thread. There are MFC examples that illustrate this. And, your
thread code only works if you receive the expected 10 packets. UDP IS NOT
RELIABLE. You can not and must not assume that you will receive all the
packets. And finally, what is the point of suspending your main thread
until the socket thread completes? This is fundamentally wrong in any
Windows program: It will lock up your window.
I am not optimistic that you can complete this assignment, and if you must
rely on UDP to give you all the packets then it is an impossible assignment
