批处理中能顺利执行的语句:

for /f "skip=9 tokens=2* delims== " %%a in ('tasklist /v /fo list /fi "imagename eq notepad.exe"') do echo %%b

现在我想使用VBS,显示进程任务标题

Set WshShell=WScript.CreateObject("WScript.Shell")
Set oExec = WshShell.Exec("cmd /c for /f " & """skip=9 tokens=2* delims== "" %%a in (" & "'" & """tasklist /v /fo list /fi ""imagename eq notepad.exe""" & "'" & ") do echo %%b")
WScript.Echo oExec.StdOut.ReadAll

结果总是空白?

问题是:如何在括号中正确使用引号,以解决单引号和双引号问题???

Set WshShell = WScript.CreateObject("WScript.Shell")
strCommand = "cmd /c @echo off&&for /f ""skip=9 tokens=2* delims== "" %a in ('tasklist /v /fo list /fi ""imagename eq notepad.exe""') do echo %b"
Set oExec = WshShell.Exec(strCommand)
WScript.Echo oExec.StdOut.ReadAll
Set oExec = Nothing
Set WshShell = Nothing

只要将双引号 再加个 双引号 就行!

@echo off 也很必要

我现在自己试了一个,即 只要是见引号 就分隔 是双引号的 """"(四个)代替 单引号的 "'" 用双引号括起来 这样也行,不过代码看上去就很烦了!

例:
msgbox "cmd /c for /f " & """" & "skip=9 tokens=2* delims== " & """" & " %%a in (" & "'" & "tasklist /v /fo list /fi " & """" & "imagename eq notepad.exe" & """" & "'" & ") do echo %%b"

cmd模式调用%%b可以么？不是bat貌似不需要转义，忘了转义的话还能用不。。。
