The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

CAsyncSocket and Multithreading

Asked by mathiasf in Windows MFC Programming

Tags:

Hi guys!

I have a small problem. In my server application I accept the connecting clients when OnAccept is called from the main thread on my server socket. I then create the client socket and put it into a list where they are globally accessed by calling threads. Meaning that Send() on the socket might be called from any thread in the application. This doesn’t’ sound good but it seem to work until now.

I have started to experience problems, the send() function is sometimes returning WSAEWOULDBLOCK which never goes away on some client sockets. Might this have anything to do with me calling the Send() function from different threads?

What is the correct way to handle WSAEWOULDBLOCK? Is it to queue the data and wait for a OnSend() ?

Any special fall pits I should have in mind when working with multithreaded applications and CAsynSocket?
