ProcessExists - How does one get the PID through 'Return Value' ? How do I print 'Sucess' ?

I'm trying to get the PID of a process called "c:\PROGRA~2\G.SKILL\Trident Z Lighting Control\hid.exe". It controls the RGB (Krap) on the RAM modules. In case you don't know what RGB RAM isrgb ram - Search (bing.com)

Absolutely loathe that RGB Krap :)

Long story short. I wrote two scripts, and both work (for the most part.

KillGskillRGB()
Func KillGskillRGB()
        ; Run Notepad
        Local $iPID = Run("c:\PROGRA~2\G.SKILL\Trident Z Lighting Control\hid.exe")

        ; Wait 5 seconds for the G.SKILL window to appear.
        ;WinWait("[CLASS:CabinetWClass]", "", 5)
        ;Local $hWnd01 = WinWait("[CLASS:CabinetWClass]", "", 5)
        ;Error Check - If 'true' script runs next command, if 'false' exits script.
        ;If NOT $hWnd01 then Exit

Local $hWnd01 = WinWait("[CLASS:CabinetWClass]", "", 5)

        ; Wait for 2 seconds.
        Sleep(2000)

        ; Close the G.SKILL process using the PID returned by Run.
        ProcessClose($iPID)
EndFunc   ;==>KillGskillRGB
If ProcessExists("hid.exe") Then
   ProcessClose ("hid.exe")
EndIf

The first gives me the PID by running it, the second kills by the Process name. 

I was poking through the help files to do this. I found this example.

#include <MsgBoxConstants.au3>

If ProcessExists("notepad.exe") Then ; Check if the Notepad process is running.
        MsgBox($MB_SYSTEMMODAL, "", "Notepad is running")
Else
        MsgBox($MB_SYSTEMMODAL, "", "Notepad is not running")
EndIf

Then I saw this.

Return Value
Success:    the PID of the process.
Failure:    0 if process does not exist.

How does one get the PID through 'Return Value' ? How do I print 'Sucess' ?

Run("notepad.exe")
Sleep(5000)
Local $pid = ProcessExists("notepad.exe")
ConsoleWrite("PID of Notepad.exe is " & $pid & @LF)
ProcessClose($pid)

Thank you - that script works perfectly. 

I see the PID In the console now :) 

I also see if an error occurs, I get a 'zero' in the console.

How would I go about using that zero for error checking?

Success is always a non-zero number (the PID), while any error is a 'zero.'

I would think a 'If/Then' to error check. I'm not sure how to go about that :)

If error is > than zero - then do something

If error is = to zero - then do something.

Thank you for any insight. I see writing a script can be easy, the troubleshooting/debugging it is a lot more difficult :D

Updated code.

KillGskillRGB()
Func KillGskillRGB()
Run("C:\Progra~2\G.SKILL\Trident Z Lighting Control\hid.exe")
Sleep(5000)
Local $pid = ProcessExists("hid.exe")
ConsoleWrite("PID of 'hid.exe' is " & $pid & @LF)
ProcessClose($pid)
EndFunc   ;==>KillGskillRGB

Can't we do the same process using task manager or command prompt? 
 

  1. Press Ctrl+Shift+Esc on the keyboard.
  2. Go to the Processes tab.
  3. Right-click the header of the table and select PID in the context menu.

The context menu in the processes window

  1. Find the process for which you need to find the PID.

Find the PID of the process in the corresponding column.

The PID column in the processes window
