How to terminate a running script from another script ?

[PKG]

Hi.

I want to know that how can i terminate a running script from another script. I use ShellExecute() to run script and I want to stop it when i press "Stop" button.

expandcollapse popup

;It is the 1st Script...

#include<GUIConstantsEx.au3>
Opt("GUIOnEventMode", 1)
Opt("MustDeclareVars", 1)
Global $PixFlag = False
Global $WinScrStart, $WinScrStop
FileInstall("ScrPix.au3", "", 1)
WinMain()
Func WinMain()
    GUICreate("WinApp-1.0", 550, 500)
    GUISetOnEvent($GUI_EVENT_CLOSE, "WinExit")
    $WinScrStart = GUICtrlCreateButton("&Start(Win)", 40, 420, 80, 30)
    GUICtrlSetOnEvent(-1, "PixCtrl")
    $WinScrStop = GUICtrlCreateButton("&Stop(Win)", 130, 420, 80, 30)
    GUICtrlSetOnEvent(-1, "PixCtrl")
    GUISetState()

    While 1
        Sleep(10)
        If $PixFlag = True Then
            FullPixSave()
        EndIf
    WEnd
    Return (0)
EndFunc   ;==>WinMain

Func WinExit()
    Exit 0
EndFunc   ;==>WinExit

Func PixCtrl()
    Switch @GUI_CtrlId
        Case $WinScrStart
            $PixFlag = True
        Case $WinScrStop
            $PixFlag = False
    EndSwitch
    Return
EndFunc   ;==>PixCtrl

Func FullPixSave()
    ShellExecute("ScrPix.au3")
    Return
EndFunc   ;==>FullPixSave

;It is the 2nd Script...

#include <ScreenCapture.au3>
WinPixStartSave()
Func WinPixStartSave()
    While 1
        Local $FileName
        $FileName = @WorkingDir & "\" & @HOUR & @MIN & @SEC & "WinScr.jpg"
        _ScreenCapture_CaptureWnd($FileName, WinGetHandle("", ""))
        Sleep(1000)
    WEnd
    Return
EndFunc   ;==>WinPixStartSave

When i run the second script, It uses 100% CPU. How can i Fix it ?

Thanks in Advance.

Use function "Run" to start "ScrPix.au3". Run returns the PID which can be used to close the process when Stop is being pressed.

BTW: Why do you need to create a screenshot once a second?

It is just an Experiment.

Thanks Water.

Or if the script you wish to stop is a compiled one, you can use ProcessClose with it's executable name.

Or use IPC (Inter Process Communication) to send a stop signal to the second script. IPC is easy to implement - one of the best examples uses mailslot (written by trancexx). Search the forum for IPC or Inter process COmmunication and you will get a lot of hits.
