Q: How to modify the default 'Open' dialog?

A:

• Delete or comment the following line added in message map of CWinApp-derived class by the AppWizard:
  

  ON_COMMAND(ID_FILE_OPEN, CWinApp::OnFileOpen)

• Using ClassWizard map yourself ID_FILE_OPEN command
  
  
• Write this code in ID_FILE_OPEN handler function:
  

  void CMyApp::OnFileOpen() 
  {
     LPCTSTR pszFilter = 
        _T("Bitmap files (*.bmp;*.dib;*.rle)|*.bmp;*.dib;*.rle|")
        _T("JPEG files (*.jpg;*.jpeg;*.jpe;*.jfif)|*.jpg;*.jpeg;*.jpe;*.jfif||");
  
     CFileDialog dlgFile(TRUE, NULL, NULL, 
                         OFN_HIDEREADONLY,
                         pszFilter,
                         AfxGetMainWnd());
  
     if(IDOK == dlgFile.DoModal())
     {
        OpenDocumentFile(dlgFile.GetPathName());
     }
  }
