Win32 实现 MFC CFileDialog 对话框

 void CWriteWnd::OpenFileDialog()

 {

     OPENFILENAME ofn;

     TCHAR szFile[MAX_PATH] = _T("");

     ZeroMemory(&ofn, sizeof(ofn));

     ofn.lStructSize = sizeof(ofn);

     ofn.hwndOwner   = *this;

     ofn.lpstrFile   = szFile;

     ofn.nMaxFile    = sizeof(szFile);

     ofn.lpstrFilter = NULL;

     ofn.nFilterIndex    = ;

     ofn.lpstrFileTitle  = NULL;

     ofn.nMaxFileTitle   = ;

     ofn.lpstrInitialDir = NULL;

     ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;

     GetOpenFileName(&ofn);//如果用户指定了一个文件名且点击OK按钮，返回值为非零值。如果用户取消或关闭Save对话框或错误出现，返回值为零。

     if (GetOpenFileName(&ofn))

     {

         //std::vector<wstring> vctString(1, szFile);//保存添加文件的路径

     }

    else

    {

        DWORD dwError = NOERROR;

        dwError = CommDlgExtendedError();

    }

 }

注:The error codes returned by CommDlgExtendedError are defined in the Cderr.h file.
