Get window(s) handle if you have PID

[fastnick1oo]

Func _WinGetHandleByPID($iPID)
    If Not IsNumber($iPID) Then
        SetError(1)
        Return 0
    EndIf
    If $iPID < 0 Then
        SetError(2)
        Return 0
    EndIf
    Local $wList = WinList()
    Local $hWnd[1][2] = [[0], [0]]
    For $i = 1 To $wList[0][0]
        If WinGetProcess($wList[$i][1]) = $iPID Then
            $hWnd[0][0] = UBound($hWnd, 1)
            ReDim $hWnd[UBound($hWnd, 1)+1][2]
            $hWnd[UBound($hWnd, 1)-1][0] = $wList[$i][0]
            $hWnd[UBound($hWnd, 1)-1][1] = $wList[$i][1]
        EndIf
    Next
    Return $hWnd
EndFunc

Is it best way to obtain window(s) handle if you just have PID?

I usually use Run() and then want to ControlSend() it, so I use my function.

Any other ideas?

This script will popup a msgbox with the Handle of the current active window.

While 1
$handle = WinGetHandle ( WinGetTitle ( "" ) )
MsgBox (4096, "handle is", $handle , 1 )
WEnd

...and if I want to do it the right way: by PID?

maybe something like this?

$handle = WinGetHandle ( WinGetTitle ( $iPID ) )

This is best. No more ideas needed.

There is an error here: Local $hWnd[1][2] = [[0], [0]]

This is nice if you know the PID... a couple of things.

Redimming constantly if there are a large amount of windows for that PID open, can be a bit slow.

If you take a look at this way (a bit longer), but you can throw in the name of the executable (mind you, this one will get z order, I usually use ProcessList and go through 2 loops (1 for the win's and 1 for the processes)), or the PID.

You have a few options as well, if want all windows visible or not... -1 if you want just non visible ones 0, or if you want only visible ones (default) 1.

A bit longer, but more options, and possibly faster if there are a lot of windows open for that PID

SmOke_N nice example, thats what I wanted to see. Really nice.

(i saw few mistakes in my code :"> )
