VC++ QQ file transfer capabilities to achieve similar file send and receive program examples, divided into server and client, the client receives the first data packet to determine the file size, the packet must contain the complete information packet structure, the data is not must complete reading packet size, including the size and structure of the data packet size, the previously received data and present the data received at least be able to constitute a complete packet, the file has been received then set the mark, if the connection is terminated, the pop-up window telling the user, the other party to terminate the file transfer.
