一段很好玩的代码，试试看！

[ttyp]

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal Scan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Sub Command1_Click()
Dim i As Long
For i = &HFF To 0 Step -1
MsgBox CStr(Hex(i))
Call keybd_event(i, 0, 0, 0)
Next
End Sub

我在winme下调试时
当i=&h5e时，关机
当i=&hb7时，掉出了计算器
当i=&h52时，掉出了运行
当i=&h5f时，进入节能模式

还有掉出了快速启动栏的东西

警告：调试时有时系统会变乱，莫名其妙，不过重起后就好了，如有新发现帖上来

呵呵，看看Virtual-Key Codes表就知道为什么了。

[ttyp]

to sundayboys(找回自我中......):哪里有，我想知道

[NowCan]

对呀，哪儿有这个表？？？

真的？

[sxbyl]

呵呵……看看MSDN的virtual-keyword, using for included files就知道了

[sxbyl]

唉呀！贴错了，是看MSDN的Virtual-Key Codes

[pcbaby]

这个在win98中能用吗？

[ninglng]

呵，真爽！
