检测应用程序是否具有管理员权限

[cheneyhehe]

VISTA, WIN7的UAC太讨厌

应用程序如何自己检测运行的时候是否具有管理权限?

// isadmin.cpp (Windows NT/2000)
// This example will show how you can know if the current process
// has administrative privileges.

#include <stdio.h>


BOOL IsAdmin(void);

Nice!thank you for your timely reply!

错了,上面只能检测当前用户是否是管理员,而无法得到当前程序是否是管理员权限执行....
