  Q1)

  How can I change the font for a list box? I am learning Visual C++ 6.  I have tried

     m_cltList.SetFont((CFont *)"Courier New") ;

  but obviously it does not work!! Please help me!!

   

  Q2)

  I am trying to develop a client application in Visual C++ 6 (the server in C and it runs well!). Receive() in the program incurs an error WSAEWOULDBLOCK!! 

   

      i.e. if ((iRcvd=m_sConnectSocket.Receive(..))==SOCKET_ERROR) {

               switch(iError=GetLastError()){

                     case WSAEWOULDBLOCK:

                                      :

            } // if

  To get around this problem, I introduced a loop which contains the Receive() statement, ignores WSAEWOULDBLOCK and breaks only when some data is received.  With this, the program runs but I feel that I have not addressed the problem correctly.  Please tell me how you would solve this problem!  Do I have to use SetSockOpt() or IOCtl() to address this problem!!  The server is in the blocking mode!!

  Many thanks

  The following is an example how to change the font for a static control...the example is a dialog-based application which does not matter regarding the setting of the font itself...

  // Dialog.hpp
  class CYourDlg : public CDialog
  {
  public:
    ~CYourDlg() { m_Font.DeleteObject(); }
    ...
  
  private:
    CFont m_Font;
  };
  
  // Dialog.cpp
  BOOL CYourDlg::OnInitDialog()
  {
    CDialog::OnInitDialog();
  
    // Creates a 12-point-Courier-font
    m_Font.CreatePointFont(120, _T("Courier"));
  
    // With a member variable associated to the static control
    m_MyStatic.SetFont(&m_Font);
  
    // Without a member variable
    GetDlgItem(IDC_MY_STATIC)->SetFont(&m_Font);
  }

  The font itself can be created in many ways...the only important thing is that the font object itself exists as long as the control...in other words....keep it as a member of the control or surrounding dialog....

  // First way
  CFont Font;
  
  Font.CreateFont(12,                            // Height
                  0,                             // Width
                  0,                             // Escapement
                  0,                             // Orientation
                  FW_BOLD,                       // Weight
                  FALSE,                         // Italic
                  TRUE,                          // Underline
                  0,                             // StrikeOut
                  ANSI_CHARSET,                  // CharSet
                  OUT_DEFAULT_PRECIS,            // OutPrecision
                  CLIP_DEFAULT_PRECIS,           // ClipPrecision
                  DEFAULT_QUALITY,               // Quality
                  DEFAULT_PITCH | FF_SWISS,      // PitchAndFamily
                  "Arial"));                     // Facename
  
  
  
  // Second way
  CFont   Font;
  LOGFONT lfLogFont;
  
  memset(&lfLogFont, 0, sizeof(lfLogFont));

  lfLogFont.lfHeight    = 12;                    // 12-pixel-height
  lfLogFont.lfWeight    = FW_BOLD;               // Bold
  lfLogFont.lfUnderline = TRUE;                  // Underlined
  
  strcpy(lfLogFont.lfFaceName, "Arial");         // Arial
  
  Font.CreateFontIndirect(&lfLogFont);
  
  
  
  // Third way
  CFont   Font;
  LOGFONT lfLogFont;
  
  memset(&lfLogFont, 0, sizeof(lfLogFont));
  
  lfLogFont.lfHeight    = 120;                   // 12-pixel-height
  lfLogFont.lfWeight    = FW_BOLD;               // Bold
  lfLogFont.lfUnderline = TRUE;                  // Underlined
  
  strcpy(lfLogFont.lfFaceName, "Arial");         // Arial
  
  Font.CreatePointFontIndirect(&lfLogFont);
