'=====================
'补充以上代码可以查找或者关闭指定的进程，函数入口参数为字符串类型，
'例如要关闭记事本，可以调用 Call KillProcess("notepad.exe")
'如果你要使关闭包含“111”字符串的进程
'可以把上面的两个函数中的 If mName = LCase(sEndProess) Then 都改为下面的语句
If Instr(nName,LCase(sEndProess)) Then 即可
然后这么调用 Call KillProcess("111") 即可杀死包含“111”的进程
不过这个函数一次只能杀死一个进程，所以你必须使用Timer控件，设置Interval为10，来不断地杀死进程
