C++语言 文件对话框的调用

void CTestDlg::OnOpen() 
{
    // TODO: Add your control notification handler code here
    //bOpenFileDialog(TRUE):'打开'对话框
    //lpszDefExt:扩展名
    //lpszFileName:文件名称
    //dwFlags:自定义文件对话框
    //lpszFilte:用于指定对话框过滤的文件类型(文件类型说明和扩展名间用"|"分隔,每种文件类型间用"|"分隔,末尾用"||"结束.)
    //pParentWnd:标识文件对话框的父窗口指针
    //CFileDialog dlg(TRUE, NULL, NULL, NULL, NULL, NULL);
