[JeffQOOQAAA]

Dear All.

I want to use Autoit get cmd output.

Here is my code, but no ouput, 

 

Please help to correct where is error, thanks!

 

  #include <Constants.au3>

    Local $hWnd = Winactivate("Administrator: Command Prompt")

    ; Display a list of Notepad processes returned by ProcessList.
    Local $aProcessList = ProcessList("cmd.exe")
    For $i = 1 To $aProcessList[0][0]
        MsgBox(0, "", $aProcessList[$i][0] & @CRLF & "PID: " & $aProcessList[$i][1])
  ;$iPID = $aProcessList[$i][1]

      Local $content = StdoutRead($aProcessList[$i][1])
      MsgBox(0, "讀取到的 STDOUT 為：", $content)

      FileWrite(@DesktopDir &"\Test.txt", $content &@CRLF)
  Next

I just ran this and it did what I would expect it to:

I had two cmd.exe processes running (according to task manager), your code went through the For loop twice, the first MsgBox reported the process name and PID, the second was empty: You are using StdoutRead, which gives you the STDOUT stream from a previously run process, but the ProcessList function call is not a child process and you do not create any other child processes, hence STDOUT is empty.

Perhaps if you explain in more detail what you want your code to do we can suggest an alternative approach?

I have an system, and execute some program will popup cmd on system

So, I need to develop autoit tool to found cmd window and output for me.

But I don't know how to implement.......

Hi,

Try checking this link if that suffice your expectation. And check with help file about Run and StdoutRead as what SlackerAl means.

Hi 

My problem is cmd create not through autoit.

I just used autoit to found already exist cmd and get output.....

Let me see if I have it clearly.

You want to get the output from a cmd.exe with Autoit? is that right? Like:

Run(@ComSpec & " /c dir > output.txt", @ScriptDir)
