@CyBoRgWaR: I want to close it automatically. Did you try my script? Did you understand the Stop button? I did tried ProcessClose as you can see in my script. Thanks for trying... @jguinch: Thanks. You pointed me to the solution which is: I have to kill all child processes. I was not aware of their existence. I added one line to your suggetion and that was it! Case $idStop $aPingProcess = _WinAPI_EnumChildProcess ( $iPid ) If Not @error Then ProcessClose($aPingProcess[1][0]) If Not @error Then ProcessClose($aPingProcess[2][0]) Or better yet: Case $idStop $aPingProcess = _WinAPI_EnumChildProcess ( $iPid ) If Not @error Then For $i=1 to $aPingProcess[0][0] ProcessClose($aPingProcess[$i][0]) Next EndIf Thanks again!

Hi there, I'm posting for the first time but have been reading and learning a great deal ever since I started using AutoIt some years ago, so BIG THANKS for all the great inputs, guys! Here is my challenge to which I didn't find answers in other posts. It is specific to Running DOS command, or actually stopping cmd.exe when called with /c. To give you the background, I'm launching processing of audio files. If the user wants to stop the processing before it finishes, I need to kill cmd.exe. But I have not been able to do that with either of the various methods available. Am I doing something wrong here? Here is a code sample with comments about my findings. #include <Constants.au3> #include <GUIConstantsEx.au3> Local $hGUI = GUICreate("Test", 220, 65) Local $idRun = GUICtrlCreateButton("Run CMD", 20, 20, 80, 25) Local $idStop = GUICtrlCreateButton("Stop", 120, 20, 80, 25) GUISetState(@SW_SHOW, $hGUI) Local $iPID = 0 While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop Case $idRun ; Run CMD with Ping command as time delay. $iPID = Run(@ComSpec & ' /c ' & 'ping -n 10 127.0.0.1', @ScriptDir, @SW_SHOW, $STDIN_CHILD + $STDERR_MERGED) ; Cannot be stoped before the -n pings ;~ $iPID = Run(@ComSpec & 'ping -n 20 127.0.0.1', @ScriptDir, @SW_SHOW, $STDOUT_CHILD) ; CMD does not even start ;~ $iPID = Run(@ComSpec & ' /k ' & 'ping -n 10 127.0.0.1', @ScriptDir, @SW_SHOW, $STDOUT_CHILD) ; Does not bring anything Case $idStop ;~ StdinWrite($iPID, "^c") ; Does not seem to stop the process as Ctrl+c would do in the console ;~ ControlSend($iPID,"","","^c") ; Does not seem to stop the process as Ctrl+c would do in the console If $iPID Then ProcessClose($iPID) ; ProcessExists returns 0 after that command but CMD does not stop nor close ;~ If $iPID Then WinClose($iPID) ; No effect ;~ If $iPID Then WinKill($iPID) ; No effect ;~ MsgBox("", "", ProcessExists($iPID), 1) EndSwitch ConsoleWrite(StdoutRead($iPID)) ; Just to see what is happening Sleep(100) WEnd GUIDelete($hGUI) Thanks for your help!
