Dear all,

I have created a server program & client program.
In the client program there is timer. when the timer expires a message is send to the server. It works fine only once. Second time the server program is not receiving the message.

client code execution when timer expires.

CSocket s;
s.Create();
s.Connect("localhost",8001);
s.Send(str,str.GetLength());
s.Close();

Can you help to solve this problem?

Thanks & regards

The problem is most likely at the server end. Does the server continue to listen for connections after the first connection?

Exaclty what winsock error number do you get at the client when you try to connect the second time?

Can you debug the server and see whats going on?

Socket Server

I have a socket server that is to establish a connection with only one client. I can accept the client fine and also receive the data from the client. My problem is that every time I want to reconnect to the server, I get a error message.

 Debug Assertion Failed!<br />
<br />
   Program: D:\TempProject\Debug\TempPrj.exe<br />
   File: sockcore.cpp<br />
   Line: 177

When I try and debug it says an unexpected breakpoint has been reached....

What does I have to do when the client disconnects? How do I get the server to come back up in the Listen() state again?

Thanks for helping a noob out.

I believe you are accepting the New Socket Connection on same variable without properly closing it...
First make a call to Close().. before acception new connection!

I do call Close() when the disconnect button is pressed. At that point I also do a Listen() which I figured would allow for the next client to connect to the server?

Any more suggestions? Would this be sufficient to have the server always be ready to accept a connection when one is not already established?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
