本文主要是介绍Win32 快捷方式操作助手类(Lnk快捷方式),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
将快捷方式的操作做了一个简单封装, 方便使用.
//解析Lnk内容
{CLnkHelper obj;obj.Load(_T("123.lnk"));SHELL_LINK_INFO info = obj.GetInfo();//TODO 使用info的内容
}//创建(另存为)快捷方式
{CLnkHelper obj;SHELL_LINK_INFO info;//TODO 修改info的内容obj.SetInfo(info);obj.Save(_T("456.lnk"));
