Giving this sample a try on the problem slider, and the slider returns null
when you ask it for the rangeValuePattern.
It says the only patterns supported are the value pattern, and the legacy
iAccessible pattern.
And, you asked earlier, whether I had tried other key strokes, and focus
leaves the slider if you press any of those arrow keys.
I think there is another reason why that is happening, which is out of my
control, and is what is making me explore this.
But, thanks for this sample. Very instructive.

Hello Snowman,
here's another possible solution, this time by using UIA. This code
example searches for the first slider ("FindFirst"). If you have several
sliders you can adjust it and use "FindAll".
Hope this helps
Udo
<code start>
Script ChangeSliderPos ()
var
object oUIA,
object oElement,
object oCondition,
object oRangePattern,
string sValue,
handle hDialog
hDialog = GetRealWindow(GetFocus())
oUIA = CreateObjectEx ("FreedomSci.UIA", 0, "UIAScriptAPI.x.manifest")
oElement = oUIA.GetElementFromHandle (hDialog)
If !oElement then Return EndIf
oCondition = oUIA.CreateIntPropertyCondition(UIA_ControlTypePropertyId,
UIA_SliderControlTypeId)
If !oCondition then Return EndIf
; search the first slider
oElement = oElement.FindFirst (TreeScope_Descendants, oCondition)
If !oElement then Return EndIf
oRangePattern = oElement.GetRangeValuePattern()
SayString (oRangePattern.Value)
; you can also get the minimum and maximum values
; or other properties (you can have a look at the UIA documentation from
FS)
; SayString (oRangePattern.Maximum)
; SayString (oRangePattern.Minimum)
; set the new value here
oRangePattern.SetValue (oRangePattern.Value -5 )
; to get the new values search for slider again
oElement = oElement.FindFirst (TreeScope_Descendants,
oCondition).BuildUpdatedCache
oRangePattern = oElement.GetRangeValuePattern()
SayString (oRangePattern.Value)
EndScript
<code end>

Hi Snowman,
did you try other key strokes on the control? Sometimes it's not the
arrow keys but page up and page down keys.
I don't know if SendMessage and PostMessage are working here. Some time
ago I searched the web for the same reason. I tried a few examples but
failed to send the keys to a control with SendMessage and PostMessage.
Good luck
Udo

Guys, is it possible to send a particualr key stroke to a particular__________�
control?
I have a case where the control takes focus, it is a slidere. But,
if you use the arrow keys, focus leaves the slider, and goes
elsewhere. I want to try sending the up and down arrow message to
the slider directly, to see if it will honor it.
I pressume this is SendMessage, or Post Message. but, I'm not sure
what to specify in the call.
Any help much appreciated.
