CSocket and CArchive

Do I have to use a CArchive to either read or send something from a CSocket class?  Any sample that I've seen so far is using the CArchive to read things from the CSocket.  Would you please give me a code sample how to read something from my socket class?  Here is the sequence:
I call Receive() from my OnReceive function.

Thank you
Allen

If you do not want to use CArchive, then use class CAsyncSocket.  CAsyncSocket is a lower level abstraction and gives you more control of the socket.

class MySocket : public CAsyncSocket
// inherit CAsyncSocket to let you use all its functions as well as adding your own overrides for notifications

// your other functions to process data...

void MySocket::OnReceive() {
   int bytesReceived = 0;
   char dataBuffer[256];
   
   // Receive() is inherited from CAsyncSocket
   bytesReceived = Receive(dataBuffer, sizeof(dataBuffer));

   // call your other member functions to process the data in dataBuffer
}

That's all there is to it.  The data received from the server is stored in dataBuffer.  The length of dataBuffer has to be worked out when you design the packets that will be sent from the server side.
