C++\Winsock - Sending std out messages problem

83 New Member
Hi,
I've been having trouble recently with sending messages to a client.
The client seems to be recieving the sever output (in the console).
This has completely done me in.

I have noticed it is to do with the buffer size.
For example:
Expand|Select|Wrap|Line Numbers
  1. send(client[i].clientsocket, "-h7-Endlist" , sizeof("-h7-Endlist"), 0); // is the previous send() call
  2. send(client[i].clientsocket, client[id].clientname, sizeof(client[id].clientname), 0);
  3. send(client[i].clientsocket, " signed in.\n" , sizeof(" signed in.\n") , 0);
Would send ' signed in.'.
And when I do somthing like this:
Expand|Select|Wrap|Line Numbers
  1. send(client[i].clientsocket, "-h7-Endlist" , sizeof("-h7-Endlist                                 "), 0); // is the previous send() call
  2.     send(client[i].clientsocket, " Says:\n" , 1000, 0);
  3.     send(client[i].clientsocket, client[id].buf , 1000, 0);
  4.  
Would show something liek:

'beta 6

Adam signed in.'

Where 'beta 6' is displayed in the server console, and strangely gets put into send() function.

Also, this worked perfectly over a LAN connect, but not over a WAN connection.
All required ports are opend and forwarded properly.

Is this my cheesy scripting? or a fixable common error?

If the data is not getting there it is much more likely to be a connection error than a send error.

How did you connect? Was it successful (i.e. not returned errors or error callbacks)?
What were the return values of your send function calls?

Thanks for posting,
I never seemed to check for send errors, I see what they return...

Bit of a bump...
I made a flash client for it as well.
But, its very odd, it displays data that even hasnt been echoed by the server.
So, Most likely a send() error.

What is the best method of using send?
send(socket, "hello", sizeof "hello", 0),
send(socket, string, sizeof string, 0),
send(socket, "hello", 1000, 0),
or send(socket, string, 1000 , 0); ?

Please?
Could the environment affect its behaviour?
It works fine on local host, just not on another pc...

Hi Guyz well I wanna implement a tcp chat program with C# and winsock, and I know that I should use Asynchronous methods so my windows program won't be blocked, but in my application both clients could send and receive messages at the same time, which means I can not begin recieving after sending a message or vice versa, it's possible that my application would recieve multiple messages, so how should I handle that?

Hi, I have a VB6 project that uses a winsock control to receive text messages over a UDP connection. It used to work fine. However, when I changed the code to make it more efficient (ie, less processing was done with each received message), the program has this weird bug where it will stop acting on the messages received. The program might work fine for a whole day, receiving thousands of messages, so it is an intermittent problem.
