PB如何结束run运行的进程？
本帖最后由 bombshell 于 2011-11-26 10:34:25 编辑 在程序中用RUN运行了一个进程，想结束某个进程，并且希望RUN程序与PB主程序系统工作，请问该调用那个API？谢谢！

下面是一个用户对象，用于获得进程PID，然后，可以用后面的脚本结束该进程。
$PBExportHeader$uf_get_exename.sru
$PBExportComments$获得进程

PB事件中的脚本例子：
这是在窗口关闭前，杀掉快播的两个进程
//用于杀掉qvod的两个进程
uf_get_exename luf_get_exename
INTEGER li_rc,j
ULONG ul_PID
ULONG PROCESS_TERMINATE = 0001
ULONG hwdprocess
String ls_exeName[]
ls_exeName[1] = "qvodplayer.exe" //要结束的进程名
ls_exeName[2] = "qvodterminal.exe"
//If messagebox('结束进程','确定吗?Kill?',question!,yesno!,1) = 2 Then return
//创建实例变量
luf_get_exename = create uf_get_exename
for j = 1 to 2
//获取指定进程号
ul_PID = luf_get_exename.of_getexe(ls_exeName[j])
If ul_PID = 0 Then
Messagebox('结束进程','没有发现进程!')
return
End If
If ul_PID <> 0 Then
//获取指定进程号的进程句柄
hwdprocess = OpenProcess(PROCESS_TERMINATE,1,ul_PID)
//结束进程,成功返回非零
li_rc = TerminateProcess(hwdprocess,0)
//If li_rc <> 0 Then Messagebox('结束进程','成功结束进程!')
End If
next
Destroy luf_get_exename;
