GUICtrlCreateSlider()

[buzz44]

Is there a way I can reverse the min and max for a slider, so instead from left to right or up to down its right/left and down/up?

Also the ClassNameNN for an AutoIt slider is msctls_trackbar321, can AutoIt also create/support msctls_trackbar322? Such as the up/down's in the tray volume window.

Anyone?

Global Const $TBS_REVERSED = 0x200

GUICreate("slider",220,220, 100,200)
GUISetBkColor (0x00E0FFFF) ; will change background color

$slider1 = GUICtrlCreateSlider (10,10,20,200,BitOR($TBS_VERT,$TBS_REVERSED))
GUICtrlSetLimit(-1,200,0); change min/max value
$button = GUICtrlCreateButton ("Value?",75,70,70,20)
GUISetState()
GUICtrlSetData($slider1,45); set cursor

$start=TimerInit()
Do
  $n = GUIGetMsg ()
     
   If $n = $button Then
      MsgBox(0,"slider1",GUICtrlRead($slider1),2)
   $start=TimerInit()
   EndIf
Until $n = $GUI_EVENT_CLOSE

Thanks for reply Gary but no go , for me anyway. I had already tried using the TBS_REVERSED style but it didn't work, nor does this, does the above work for you?

I'm running XP PRO SP 2, tested with v3.1.1.53.

Nope, but read a little more, from MSDN:

TBS_REVERSED

Version 5.80.This style bit is used for "reversed" trackbars, where a smaller number indicates "higher" and a larger number indicates "lower." It has no effect on the control; it is simply a label that can be checked to determine whether a trackbar is normal or reversed.

If I get time I'll look into how to check for that, unless a dev has an answer.

Thanks.

Blah, thanks again Gary, I didn't think to do that lol.

Instead of changing the value to a negative and multiplying it by -1 etc I'm just going to do...

GUICtrlSetLimit(-1,200,0) ; change min/max value
;....
   If $n = $button Then
      MsgBox(0,"slider1",200 - GUICtrlRead($slider1) ,2)
;....
