ProcessList | Error : Subscript used on non-accessible variable.

[Nevi]

Could anyone show me what's wrong here?

Func _getPID($ProcessName)


Local $i = 0
Local $PID = 0


While ( $i + 1 <= ProcessList($ProcessName)[0][0] )
$PID[$i] = ProcessList($ProcessName)[$i+1][1] ; probably this one.
$i = $i + 1
WEnd


Return ($PID)


EndFunc




_getPID("explorer.exe")

Thank you.

Why not just use

ProcessList('explorer.exe')

?

EDIT: If you have the error please post it, I bet it is has to do with the fact that your trying to use a regular variable as an array like so

$PID[$i]

ProcessList -

Returns an array listing the currently running processes (names and PIDs).

Thanks. However, how do you list the PID of multiple processes with the same name?

I'm a bit confused, now.

 

PS: The error is in the title. Sorry for the confusion.

Return Value
Success:    an array of process names and PIDs (See Remarks).
Failure:    sets the @error flag to 1 when the array cannot be built.
Remarks
The array returned is two-dimensional and is made up as follows:
    $aArray[0][0] = Number of processes
    $aArray[1][0] = 1st Process name
    $aArray[1][1] = 1st Process ID (PID)
    $aArray[2][0] = 2nd Process name
    $aArray[2][1] = 2nd Process ID (PID)
    ...
    $aArray[n][0] = nth Process name
    $aArray[n][1] = nth Process ID (PID)

The list can be empty if $aArray[0][0] = 0. No @error set in this case.

The helpfile is your friend

If that wasn't clear it will list all running names and PIDs of the process.

You initalize $PID to 0, then call the function passing the ProcessName, but never do anything more with $PID. Why wouldn't you get an error? Try this to see why it is failing:

Func _getPID($ProcessName)
    Local $i = 0
    Local $PID = 0

    While ( $i + 1 <= ProcessList($ProcessName)[0][0] )
        If Not IsArray($PID) Then
            MsgBox(0, "", "$PID is NOT an array so $PID[$i] will FAIL. $PID = " & $PID)
            Exit
        EndIf
        $PID[$i] = ProcessList($ProcessName)[$i+1][1] ; probably this one.
        $i = $i + 1
    WEnd

    Return ($PID)
EndFunc

This will fail everytime. obviously it will, but isn't doing this much work a little redundant or am I just being dumb?

Precisely the point I am trying to make - the OP is asking why his code is failing. That demonstrates why.

Thank you very very much!

Ah, I see they just skipped over
