Hi all, Using CPP Builder 6 update 4 Windows XP SP2 I have a client/server set of apps, the client uses a TClientSocket and the server the TServerSocket, all works great data sent back and forward fine, apart from one or two places. The problem seems to be when I send several packets straight after each other, the packets are all sent within a thread that activates every 35 ms and it sends one packet at a time. For some reason though several packets seem to get concatenated together to form one larger packet, if I slow down the transmit thread to say every 200ms this problems dissapears, this sort of time delay however is unacceptable. What I would like to know is: Is there anyway to determine whether the last packet was sent before I attempt to send the next one i.e. a buffer empty flag or check function, if the packet was not sent I can delay the transmit to the next activation of my thread and check again, thus curing the concatenation problem. Your thoughts would be appreciated. Thanks Joe
