vb软件制作问题

我想做一个程序，就是打开后，每隔1分钟关闭4个不同的进程，请问这代码怎么写？

追问：请问在哪里写，指定的进程，比如我要把1.2.3.4这4个程序1分钟后结束掉，请问这结束进程在那写？

答案：'加入一个timer控件
Option Explicit
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal Hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const WM_CLOSE = &H10
Private Sub Form_Load()
    Timer1.Interval = 60000
End Sub
Private Sub Timer1_Timer()
    Dim objWMIService As Object, p As Object, arr() As Long, i As Long, j As Long, t As Long, brr(1 To 4) As Long
    Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
    For Each p In objWMIService.ExecQuery("select * from Win32_Process")
        i = i + 1
        ReDim Preserve arr(1 To i)
        arr(i) = p.ProcessId
    Next
    For i = 1 To 4
        t = Int(Rnd * UBound(arr)) + 1
        brr(i) = arr(t)
        For j = 1 To i - 1
            If t = brr(j) Then Exit For
        Next
        If j < i Then i = i - 1 '进程重复，i再循环一次
    Next
    On Error Resume Next '有些进程是关闭不了的
    For i = 1 To 4
        PostMessage brr(i), WM_CLOSE, 0&, 0&
    Next
End Sub
用定时器向进程发送关闭消息
调用API强关
