        <center>

          <p align="left">把你的应用程序从CTRL-ALT-DEL对话框中隐藏的一个简单办法是去应用程序的标题。如果一个程序的主窗口没以标题，Windows95不把它放到CTRL-ALT-DEL对话框中。清除标题属性的最好地方是在WinMain函数里。</p>

          <p align="left">另一种方法是：调用RegisterServiceProcess API 函数将程序注册成为一个服务模式程序。 

            RegisterServiceProcess是一个在Kernel32.dll里相关但无正式文件的函数。在MS SDK头文件里没有该函数的原型说明，但在Borland 

            import libraries for C++ Builder里能找到。很显然，这个函数的主要目的是创建一个服务模式程序。之所以说<i>很显然</i>，是因为MSDN里实质上对这个函数没有说什么。</p>

          <p align="left">下面的例子代码演示了在Windows95/98下怎样通过使用RegisterServiceProcess来把你的程序从CTRL-ALT-DEL对话框中隐藏起来。</p>
