rem 2、打开网页后,几秒内自动关闭网页(假设为8秒) 
@echo off 
echo set ierunner=createobject("wscript.shell") > ie.vbs 
echo ierunner.run "cmd /c start iexplore 
http://www.baidu.cn",0 >>ie.vbs 
echo wscript.sleep 8000 >> ie.vbs 
echo ierunner.sendkeys "%%{F4}" >> ie.vbs 
cscript //nologo ie.vbs 
del ie.vbs 
ie.vbs(4, 1) Microsoft VBScript 运行时错误: 无效的过程调用或参数
网页没有关闭 
请问那里出错了
