配置 MSI 文件以在安装时启动并终止程序

Question

我有一个在Visual Studio 2010中开发的应用程序，需要配置安装程序(作为.msi文件(以启动程序，然后终止任务。我在 msi 中有一个自定义操作来启动程序，但我在添加步骤来终止任务时也遇到了问题。任何建议都会很棒。谢谢！

您需要创建自定义操作才能处理此问题。Windows Installer 沒有 kill process 事件。下面是我为处理此问题而创建的本机C++应用程序。

// KillProc.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>
#include <algorithm>
#include <string> 
BOOL KillProcess(_TCHAR* szProcessToKill);
TCHAR* AcTcharlower(TCHAR *pString);
int _tmain(int argc, _TCHAR* argv[])
{
if(argc > 1){
KillProcess(argv[1]);
}else{
// No Process found
}
return 0;
}
BOOL KillProcess(_TCHAR* szProcessToKill){
HANDLE hProcessSnap;
HANDLE hProcess;
PROCESSENTRY32 processEntry32;
LPWSTR lpszBuffer = new TCHAR[MAX_PATH];
LPWSTR lpszProcessToKill = new TCHAR[MAX_PATH];
lpszProcessToKill = AcTcharlower(szProcessToKill);
hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);  // Takes a snapshot of all the processes
if(hProcessSnap == INVALID_HANDLE_VALUE){
return( FALSE );
}
processEntry32.dwSize = sizeof(PROCESSENTRY32);
if(!Process32First(hProcessSnap, &processEntry32))
{
CloseHandle(hProcessSnap);     
return( FALSE );
}
do
{
lpszBuffer = processEntry32.szExeFile;
if(!wcsicmp(lpszBuffer,szProcessToKill)){    // Is this our Process
hProcess = OpenProcess(PROCESS_TERMINATE,0, processEntry32.th32ProcessID);  // It is so get the process handle
TerminateProcess(hProcess,0);
CloseHandle(hProcess); 
} 
}while(Process32Next(hProcessSnap,&processEntry32));  // gets next member of snapshot
CloseHandle(hProcessSnap);  // closes the snapshot handle
return( TRUE );
}
TCHAR* AcTcharlower(TCHAR *pString)
{
static TCHAR pBuffer[MAX_PATH];
TCHAR *s = pString;
TCHAR *t = pBuffer;
while (*s != '')
{
*t = tolower(*s);
s++;
t++;
}
return(pBuffer);
}
