从任务列表中隐藏 按Ctrl+Alt+Del时也不会显示出来  

程序说明:

　　这个程序比较简单,只使用了GetCurrentProcessId 和 RegisterServiceProcess 两个函数就可以达到。

　　这种方法只能在 Windows98 中运行,在 Windows2000中是不行的

　　程序代码:

Module1

Public Declare Function GetCurrentProcessId Lib "kernel32" () As Long
Public Declare Function RegisterServiceProcess Lib "kernel32" (ByVal dwProcessID As Long, ByVal dwType As Long) As Long
Public Const RSP_SIMPLE_SERVICE = 1
Public Const RSP_UNREGISTER_SERVICE = 0

下面代码为隐藏

Public Sub MakeMeService()
Dim pid As Long
Dim reserv As Long
pid = GetCurrentProcessId() 注释：取的当前运行的程序Id

regserv = RegisterServiceProcess(pid, RSP_SIMPLE_SERVICE)
对当前的程序传入 RSP_SIMPLE_SERVICE 消息,使此程序
从任务列表中隐藏
End Sub

注释：恢复隐藏
Public Sub UnMakeMeService()
Dim pid As Long
Dim reserv As Long
pid = GetCurrentProcessId()
regserv = RegisterServiceProcess(pid, RSP_UNREGISTER_SERVICE)
原理同上
End Sub

Private Sub Command1_Click()
Call MakeMeService
End Sub

Private Sub Command2_Click()
Call UnMakeMeService
End Sub

Private Sub Form_Load()
Form1.Left = Screen.Width / 2 - Form1.Width / 2
Form1.Top = Screen.Height / 2 - Form1.Height / 2
End Sub
