Using CBitmapButton in CDialogBar and CFormView

WINDOWS             | WINDOWS NT

The information in this article applies to:

• The Microsoft Foundation Classes (MFC) included with:

      - Microsoft Visual C++ for Windows, versions 1.0, 1.5, 1.51, and
        1.52
      - Microsoft Visual C++ 32-bit Edition, versions 1.0, 2.0, 2.1, 2.2,
        and 4.0
  

To attach a CBitmapButton object to a button in a dialog box, call the CBitmapButton::AutoLoad() function in the OnInitDialog() function for the dialog box. Note, that the CDialogBar and CFormView classes are not derived from the CDialog class and do not have an OnInitDialog() function.

To use a CBitmapButton with a CDialogBar, override the Create() function and call AutoLoad() after calling the base class version of Create(). In the following code, which demonstrates this process, the CMyDialogBar class is derived from CDialogBar and m_MyBitmapButton is a CBitmapButton member of CMyDialogBar:

   BOOL CMyDialogBar::Create(CWnd* pParent, UINT nIDTemplate,
                             UINT nStyle, UINT nID)
   {
      // Call base class create to create the dialog bar window.
      BOOL bReturn = CDialogBar::Create(pParent, nIDTemplate,
                                        nStyle, nID);
      // Load bitmaps for the button and attach
      // to the control in the dialog box.
      if (bReturn)
         m_MyBitmapButton.AutoLoad(IDC_MYBITMAPBUTTON, this);

      return bReturn;
   }

   void CMyFormView::OnInitialUpdate()
   {
      CFormView::OnInitialUpdate();
      m_MyBitmapButton.AutoLoad(IDC_MYBITMAPBUTTON, this);
   }
