CAsyncSocket

//////////////////////////////////////////////////////
// Help me !
//
// I am makeing a sync communication by using TCP/IP
// Following is the code and programming sequence
///////////////////////////////////////////////////////
// IPADRESS :203.248.101.130
// PORT ADDRESS : 7
// above is echo server at our company , and I checked that
// echo server received data and responsed it
//
// some of telnet program send data and get the response
// but my program sended data but got no response
//
// as you can see the my code sequence, I don't want to use
// OnReceive() function supported CAsyncSocket class at MFC
// just want to use Receive function as soon as sending data
//
// I want drive a class from CAsyncSocket class in MFC
/////////////////////////////////////////////////////////////
//
// Code Sequency
//
// send data 1
// client -----------------------------> host
// <----------------------------
// response
//
// send data #2
// client -----------------------------> host
// <----------------------------
// response

// Following is my code at my program.

* m_Sock.Send(strTmp,strlen(strTmp));

memset(&strTmp,0x00,sizeof(strTmp));
* m_syncSock.Receive(strTmp,strlen(strTmp)); // read data from sock
AfxMessageBox(strTmp); // here I wnat to see the data
}

///////////////////////////////////////////////
// 1) Here I wonder if is is possible or not,
// 2) Is any setting is wrong ?
// 3) Is there other solutions for this problem?
//
// PS : Rapid response is highly appreciated.

Why don't you use the CSocket class ? If you don't need asynchronous operations you should use CSocket.
