在vb中怎样编一段可以强迫关闭其他正在运行的程序的代码

Private Type PROCESSENTRY32

th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long

szExeFile As String * 260

Private Declare Function TerminateProcess Lib "kernel32" (ByVal ApphProcess As Long, ByVal uExitCode As Long) As Long
Private Declare Sub CloseHandle Lib "kernel32" (ByVal hPass As Long)
Private Const TH32CS_SNAPPROCESS = &H2&'关闭指定名称的进程
Private Sub KillProcess(sProcess As String)
Dim lSnapShot As Long

Dim tPE As PROCESSENTRY32
lSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0&)
If lSnapShot <> -1 Then
tPE.dwSize = Len(tPE)
lNextProcess = Process32First(lSnapShot, tPE)
Do While lNextProcess
If LCase$(sProcess) = LCase$(Left(tPE.szExeFile, InStr(1, tPE.szExeFile, Chr(0)) - 1)) Then
Dim lProcess As Long
Dim lExitCode As Long
lProcess = OpenProcess(1, False, tPE.th32ProcessID)
TerminateProcess lProcess, lExitCode
CloseHandle lProcess
End If
lNextProcess = Process32Next(lSnapShot, tPE)
Loop
CloseHandle (lSnapShot)

End Sub调用方法: Call KillProcess("explorer.exe")

TerminateProcess(进程句柄 ,退出码）;
