用vc怎么关闭一个外部程序？

终止指定进程

#include "tlhelp32.h"

void KillExe(const char* szExeName)

{

if (szExeName == NULL)

return 0

int lsr = lstrlen(szExeName)

if (lsr == 0)

return 0

PROCESSENTRY32 my

HANDLE l = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)

if (((int)l) != -1)

{

my.dwSize = sizeof(my)

if (Process32First(l, &my))

{

do

{

if (lstrcmpi(szExeName, my.szExeFile + lstrlen(my.szExeFile) - lsr) == 0)

{

HANDLE hProcessHandle

hProcessHandle = OpenProcess(0x1F0FFF, true, my.th32ProcessID)

if (hProcessHandle != NULL)

{

if (TerminateProcess(hProcessHandle, 0) != NULL)

{

CloseHandle(hProcessHandle)

}

}

CloseHandle(l)

return

}

}while (Process32Next(l, &my))

}

CloseHandle(l)

}

}

调用方式

KillExe("c:\\windows\\notepad.exe")

完整或部分路径名，不区分大小写

Process[] ps = Process.GetProcesses()//获取计算机上所有进程

foreach (Process p in ps)

{

if (p.ProcessName == "QQ")//判断进程名称

{

p.Kill()//停止进程

}

}
