以下是MSDN中打开对话框的示例:

void CMyClass::OnFileOpen()
{
   // szFilters is a text string that includes two file name filters:
   // "*.my" for "MyType Files" and "*.*' for "All Files."
   TCHAR szFilters[]= _T("MyType Files (*.my)|*.my|All Files (*.*)|*.*||");

   // Create an Open dialog; the default file name extension is ".my".
   CFileDialog fileDlg(TRUE, _T("my"), _T("*.my"),
      OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, szFilters);

   // Display the file dialog. When user clicks OK, fileDlg.DoModal() 
   // returns IDOK.
   if(fileDlg.DoModal() == IDOK)
   {
      CString pathName = fileDlg.GetPathName();

      // Implement opening and reading file in here.

      //Change the window's title to the opened file's title.
      CString fileName = fileDlg.GetFileTitle();

      SetWindowText(fileName);
   }
}

对于“另存为”对话框,只需通过以下方式更改CFileDialog调用:

   CFileDialog fileDlg(FALSE, _T("my"), _T("*.my"),
        OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, szFilters);

备注:

  • 有些参数是可选的。
  • szFilters 包含您需要的文件扩展名。
