Check if Server Socket is Active?? 1

[Wings]

Hi,
I have created a server/client socket based chat program.
The only problem is that I have no idea how to go about checking whether or not the server is active before Attempting to activate the client socket, and recieving a socket error due to an inactive server. Any method of checking or error handling this problem would be appreciated.

Thanks

this will tell you one method of detecting socket errors. There are a few arguments that will tell you if a server is active or not, they are all inside the OnError event.

this is the error code I use to determine if the server is running or not.

switch (ErrorCode)
{
case 10061:
/* Connection refused */
Label1->Caption = "Server currently down (10061)";
break;
}

look in the
"Help->MS SDK Help Files->Windows Sockets 2 Reference" and look for their error codes. They have a complete list. I typically use all of the possible errors, but the one given will tell you if the server is down or not. Cyprus
