不能正常关机(100分)

自己的一个软件，最小化后变为托盘图标。
不能正常关机。
可否重载关机消息？如何去做？
100分奉上。请各位大虾不吝赐教

截获 WM_QUERYENDSESSION 将 Result 置 True，代表同意系统关机。

Beta,
不行呀
我的系统 Win2k Server, Eng, 如果截获消息，没问题，可以截获到。
但是置为True后系统就没动静了。不能够关机。

还有没有其他的方法？或者是我的问题？
最好是Win98/WinME/WinXP/Win2k都可以用的。
谢谢

没有
怎么设定让win2000在一定时间后自己关机
win2000和nt的关机机制和win98不一样
必须调用AdjustTokenPrivileges使se_shutdown_name有效

你的程序是否使用了网络控件？例如NMUDP？
