Re: Again with CAsyncSocket

I think I solved partially, but just for one client connection.
I got this:

class MySocket : public CAsyncSocket
{
    // Attributes
    public:
    // Operations
    public:
        int numclients;
        MySocket* clients;
        MySocket();
        virtual ~MySocket();
        void Open( MySocket* clients);
        void enviarDatos();
[...]

void MySocket::Open( MySocket* client)
{
    this->clients = client;
    this->numclients = 0;

    int ret = this->Create( 15000 );
    if( Listen()==FALSE )
    {
        UINT uErr = GetLastError();
        TCHAR szError[256];

                 wsprintf(szError, "Server Receive Socket Create()
failed: %d", uErr);
                 AfxMessageBox(szError);
    }
}

void MySocket::OnAccept(int nErrorCode)
{
    if( Accept( *this->clients ) )
    {
        AfxMessageBox("YEAH");
    }
    else
    {
        AfxMessageBox( "ERROR");
    }

    CAsyncSocket::OnAccept(nErrorCode);
}

void MySocket::SendMyData()
{
    int count = this->clientes->Send("C", 2, 0);
    if( count==SOCKET_ERROR )
    {
        AfxMessageBox("BAD");
    }
    else
    {
        AfxMessageBox( "OK");
    }
}
void MySocket::OnReceive(int nErrorCode)
{
    AfxMessageBox("OnReceive");
    int iRecvd;
    char pBuff[100];
    iRecvd = Receive(&pBuff, 100);
    //did we recieve anything?
    if(iRecvd == SOCKET_ERROR)
    {
        AfxMessageBox("Socket Error!");
    }
    else
    {
        AfxMessageBox("NO socket error");
    }

    CAsyncSocket::OnReceive(nErrorCode);
}
}

In my Dialog I have two instances of MySocket:
MySocket* server;
MySocket* clients;

In OnInitDialog : clients = new MySocket();

To test all thing:
void CCasyncDlg::OnButtonOpen() //A button to open the server
{
    server = new MySocket();
    server->Open( this->clientes );
}

void CCasyncDlg::OnSendData() //A button to send data to test
{
    server->SendMyData();
}

I think I'm starting to understand the whole thing. But I still have
some questions:
1#
To implement multiplie clients I think I should:
Change the definition of:
      "MySocket* clients"
to
      "MySocket** clients"
And implement a way to insert/remove new clients every time someone
connects to server.
I tried a CList but (including #include <afxtempl.h> and typing in
MySocket class:
typedef CList <MySocket*, MySocket*> ClientList;
CList clients;

but this throws an error:
error C2955: 'CList' : use of class template requires template
argument list
        c:\XXXXXXXXXXXX\vc98\mfc\include\afxtempl.h(653) : see
declaration of 'CList'

2# I inspected the data sended ("C") And the client received (In Hex)
43 00. I suppose that in my test I'm sending a String, but in the
final program I should send an unsigned char array. Should I use the
same function?
Bear in mind that I should be able to send null characters (0x00)
without any complication.
