oÝ÷ Ø    Ýi6)¶¬jëh×6
$Tab1 = GUICtrlCreateTab(0, 10, 480, 580)

Just a question (I could care less). If the $WS_VSCROLL is listed in the helpfile as a window style available, why isn't it supported?


Who else would I be?

search the help and you'll see what all it is used in.

Don't argue with an idiot; people watching may not be able to tell the difference.

Every control is a window, so any Window Style is for a window, whether a top level window or a control.

@Holger - Works nicely! Just one small addition to scrolling function to limit the scrolling

Func MY_WM_VSCROLL($hWnd, $Msg, $wParam, $lParam)
    $nScrollCode    = BitAnd($wParam, 0x0000FFFF)
    $nPos        = BitShift($wParam, 16)
    $hwndScrollBar  = $lParam
   
    GUICtrlSetData($nInfoLbl, $nScrollCode & ";" & $nPos & ";" & $hwndScrollBar & ";" & $yPos)
   
    $nDiff = 0
    Switch $nScrollCode
        Case 0
            $nDiff = 5
        Case 1
            $nDiff = -5
        Case 2
            $nDiff = 50
        Case 3
            $nDiff = -50
    EndSwitch

    $yPos = $yPos - $nDiff
