Thread: Winsock, weird sideeffect

I got this odd error where if I send some data from a client to a server the message is received but I also get a number of empty messages, the same amount as the nr of letters in the message (in the example below, the string "Hello" gets 5 empty messages.
It's a non-blocking system, the client sends simply using send() and the server's recieve-part looks like this:

Code:

case FD_READ:
{
	CHAR Char;
	INT Result;
	std::string String;
	std::vector<CHAR> Buffer;

	while(TRUE)
	{
		Result = recv(W, &Char, 1, 0);
				
		if(Result == SOCKET_ERROR)
		{
			if(WSAGetLastError() == WSAEWOULDBLOCK) break;
			ErrorMessage = "recv() failed!";
			return FALSE;
		}

		if(Result < 1) break;

		Buffer.push_back(Char);
	}

	Buffer.push_back('\0');
	String = "MSG: ";
	String += &Buffer[0];
	AddMessage(String);

	return TRUE;
}

As an example, if the client sends the string "Hello" to the server it would receive these messages:

Code:

MSG: Hello
MSG:
MSG:
MSG:
MSG:
MSG:

Prolly some stupid error, but I just can't find it...
