윈속을 사용하여 간단한 채팅을 만드는데요...

SOCKET sClient;
bool TCommWin::InitSocket()
{
        //TODO: Add your source code here
WSADATA WSAData;
int iRet;
char szError[40];

    // load the correct version of the Winsock library
    iRet = WSAStartup(MAKEWORD(2, 2), &WSAData);
    if(iRet != 0)
            return false;
        sClient = CreateClientSocket();

        return true;
}
//---------------------------------------------------------------------------

SOCKET TCommWin::CreateClientSocket()
{
        //TODO: Add your source code here
SOCKET Sock;
char szError[40];

    Sock = socket(AF_INET, SOCK_STREAM, 0); // create a socket
    if(Sock == INVALID_SOCKET){
        wsprintf(szError, "socket() failed: %d", WSAGetLastError());
        ShowMessage(szError);
        return INVALID_SOCKET;
    }
    if(WSAAsyncSelect(Sock, hSockWin, WM_SOCKET, FD_CONNECT|FD_READ) != 0){
        wsprintf(szError, "WSAAsyncSelect() failed: %d", WSAGetLastError());
        ShowMessage(szError);
        closesocket(Sock);
        return INVALID_SOCKET;
    }
    return Sock;
}

sClient = CreateClientSocket();에서 리턴값이 잘못됐다는 메시지가 계속뜨고 있네요...

ws2_32.lib도 Add했구요...
고수님의 도움을 기다립니다.
