从百度知道看的，VB监视进程：
让VB程序监视进程中的名称“Windows 任务管理器”,和“AAA”两个进程的进程名，
而且进行操作：如果“Windows 任务管理器”被关闭时则自动关闭“进程某某”程序！
可以用一个 Timer 定时执行下面的代码
Dim Handle As Long
Handle = FindWindow(vbnullstring,"Windows 任务管理器")
Dim Handle2 as long
Handle2 = FindWindow(vbnullstring,"进程某某")
if not (Handle) then
SendMessage Handle2,WM_CLOSE,0
Option Explicit
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String,ByVal lpWindowName As String) As Long
Private Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hwnd As Long,lpdwProcessId As Long) As Long
Private Declare Function TerminateProcess Lib "kernel32" (ByVal hProcess As Long,ByVal uExitCode As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long,ByVal bInheritHandle As Long,ByVal dwProcessId As Long) As Long
Private Sub Timer1_Timer()
Dim Handle As Long
Dim handle2 As Long
Dim ProHandle As Long
Dim ProcessHandle As Long
Handle = FindWindow(vbNullString,"Windows 任务管理器")
If Handle = 0 Then
handle2 = FindWindow(vbNullString,"进程某某")
GetWindowThreadProcessId handle2,ProHandle
ProcessHandle = OpenProcess(1,ProHandle)
TerminateProcess ProcessHandle,0
End If
End Sub
