Re: Winsock Control

Well, after investigating in the morning I could write this code to
try the CAsyncSocket.
I'm blocked in receiving the data, CAsyncSocket.receive returns a -1
error and calling GetLastError can't
get any details of what is failing.

I've created a new class that wraps CAsyncSocket (MySocket).
In my app header ( CUart2Dlg ) I create two instances of MySocket
( m_SocketServer and m_SocketListener ).
Inside MySocket I throw the events to the CUart2Dlg to write there the
code.

Here the definition of my class Dialog:
<CODE>
class CUart2Dlg : public CDialog
{
// Construction
public:
    CUart2Dlg(CWnd* pParent = NULL); // standard constructor
    void OnAccept();
    void OnClose();
    void OnRecieve();
    // [...]
private:
    MySocket m_SocketServer;
    MySocket m_SocketListener;

    // [...]
</CODE>

This is my initDialog application:

<CODE>
BOOL CUart2Dlg::OnInitDialog()
{
    CDialog::OnInitDialog();

    // Set the icon for this dialog. The framework does this
automatically
    // when the application's main window is not a dialog
    SetIcon(m_hIcon, TRUE); // Set big icon
    SetIcon(m_hIcon, FALSE); // Set small icon

    //MINE
    m_SocketServer.SetParentDlg( this );
    m_SocketListener.SetParentDlg( this );
    return TRUE; // return TRUE unless you set the focus to a control
}
</CODE>

And the event handlers:
<CODE>
void CUart2Dlg::OnClickOpenServer()
{
    // TODO: Add your control notification handler code here
    UpdateData(true);

    m_SocketServer.Create( m_iTcpPort );

    //Empezamos a escuchar
    if( m_SocketServer.Listen()==FALSE )
    {
        AfxMessageBox( "Unable to listen on that port, please try another
port" );
        m_SocketServer.Close();
        return;
    }

    addString( IDC_TCPDEBUG, _T("Waiting for conection...\r\n") );
}

void CUart2Dlg::OnAccept()
{
    CString strIP;
    UINT port;
    if(m_SocketServer.Accept( m_SocketListener ) )
    {
        m_SocketServer.GetSockName( strIP, port );
        addString( IDC_TCPDEBUG, _T("Client connected: " + strIP+"\r\n" ) );
        m_SocketServer.Send("Connected To Server",strlen("Connected To
Server"));

    }
    else
    {
        AfxMessageBox("Cannoot Accept Connection");
    }
}

//Al recibir datos
void CUart2Dlg::OnRecieve()
{
    //char *pBuf =new char [1025];
    unsigned char* pBuf[100];

    CString strData;
    int iLen;
    iLen = m_SocketServer.Receive( pBuf,100 );

    /*
    strData.Format( _T("Data length recieved:%d"), iLen );
    MessageBox( strData );
    */

    if(iLen==SOCKET_ERROR)
    {
        AfxMessageBox("Could not Recieve");
        strData.Format( _T("Error: %d"),m_SocketServer.GetLastError() ); //
<---Returns 0
    }
    else
    {
        AfxMessageBox( "Yes");
    }
}
</CODE>
