java代码实现弹出系统关机界面，关机菜单

根据资料看，系统关机重启动菜单在Shell32.dll中。这个函数是微软未公开的。处于60（十进制）的位置。

我们用RUNDLL32.EXE可以直接验证一下： rundll32.exe shell32.dll #60

注意必须写作 #60 ,其余的会不认识哦~ 可以正常出现对话框。

RUNDLL32.EXE的用法如下：

RUNDLL32.EXE <dll的文件名>,<入口地址> <可选参数>

 

=====java版本：

public class test { public test() { } public static void main(String args[]){ try { Runtime r = Runtime.getRuntime(); r.exec("rundll32.exe shell32.dll #60"); } catch (Exception exc) { exc.printStackTrace(); } } }

=====C++版本

 

就是调用命令行参数，和其他语言相同。

=====汇编语言程序版本：
