如何杀掉调用文件进程
在做一个自动更新的程序，遇到如下问题。
正常的时候用户打开软件（下面叫做用户客户端），这时候检测服务器上是否有新版本
如果有新版本则由本软件内使用shell启动自动升级程序（另一个小软件了）
然后在这个小软件里杀掉用户客户端进程，并且删除该文件，再从服务器拷贝
新版本的用户客户端来
这样来实现自动升级
问题是如何在自动升级程序中杀掉用户客户端
已经试了如下代码没能实现
Option Explicit
Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szExeFile As String * 260
End Type
Private Declare Function CreateToolhelp32Snapshot Lib "kernel32" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long
Private Declare Function Process32First Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function Process32Next Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal blnheritHandle As Long, ByVal dwAppProcessId As Long) As Long
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
Public Sub KillProcess(sProcess As String)
Dim lSnapShot As Long
Dim lNextProcess 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 If
End Sub
'调用KillProcess来杀掉进程
