• Scott Chang TcpClient.BeginAcceptTcpClient / Socket.BeginAccept / all other variations...

  I've been having a problem with the use of any of the async methods of TcpClient, Socket, etc eating >95% cpu after receiving the first connection. I've been working on this for over a week now and I'm unable to find references to this issue anywhere. I've tried every way I can think of to work around this problem. Even if no data is sent or received on the connection....or if I close the received connection -- some unknown thread uses all the available cpu power after the first connection occurs. I created a small project that reproduces the problem -- I've zipped it up and posted it here: http://www.profitfuel.net/TcpClientProblem.zip If anyone knows how to fix this, please let me know.

• manu.aretuseo Not able to save data to database

  I am thinking that this is actually a very easy issue, but I can not figure it out and am hoping someone can help me. I have a database setup with no data yet.

The Save Data icon never becomes active and if I click on the Add New icon again, I get an error about the auto-increment field not being allowed to be null. When I ...Show All
