Is it possible to set the slider bar value for an HtmlView gadget?

There is no MaxGUI command for it, but you could use JavaScript.
The example below will load a page and when done scroll to the bottom...

SuperStrict
Import MaxGui.Drivers

Global	HTMLView1:TGadget

Local Window3:TGadget = CreateWindow:TGadget("Window3",469,126,584,373,Null,WINDOW_TITLEBAR|WINDOW_RESIZABLE |WINDOW_STATUS |WINDOW_CLIENTCOORDS |WINDOW_CENTER)
	HTMLView1:TGadget = CreateHTMLView:TGadget(0,0,584,373,Window3:TGadget,Null)
		HtmlViewGo( HTMLView1:TGadget,"http://www.blitzmax.com/Community/posts.php?topic=91243")
		SetGadgetLayout( HTMLView1:TGadget,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED )

Repeat
	WaitEvent()
	Select EventID()
		Case EVENT_WINDOWCLOSE
			Select EventSource()
				Case Window3	Window3_WC( Window3:TGadget )
			End Select

		Case EVENT_GADGETDONE
			Select EventSource()
				Case HTMLView1	HTMLView1_GD( HTMLView1:TGadget )
			End Select

	End Select
Forever

Function Window3_WC( Window:TGadget )
	DebugLog "Window Window3 wants to be closed"
	End
End Function

Function HTMLView1_GD( HTMLView:TGadget )
	DebugLog "HTML View HTMLView1 has finished loading the page"
	DebugLog "URL= " + HtmlViewCurrentURL$( HTMLView:TGadget )
	HtmlViewRun$( HTMLView1:TGadget,"window.scrollTo(0,document.body.scrollHeight);")
End Function

Is there a way to scroll by a percentage? Each page has a different height and I can't seem to get it right.

Any ideas?

I tried adding a simple modifier:

HtmlViewRun(HTML, "window.ScrollTo(0, document.body.scrollHeight*"+ScrollPercent+");")

This seems to work fine on the first page but then whenever I navigate to a new page it is no longer accurate.

Sorry, I am no JavaScript expert, so it looks like the scrollheight is may not referencing the current value.
You could post this question in the general discussion forum as there are some good people doing webdesign and know such stuff, or post in a forum specialized for JavaScript.
