Hi all,
I would like to mimic the same behavior that happens on many of Microsoft's
web pages where the "Install Microsoft Silverlight" popover box appears.
That would include the "fogging" and apparent disabling of the underlying
page, and the fact that the box does not have any navigation controls, as it
is apparently not a Window.

I am using VB and ASP.NET 2.0 but I could upgrade to VS 2008 if necessary as
I like the JSON/Web Service model of AJAX better (even though I have MUCH to
learn about it).

I have done some similar things, but in a much more simplistic fashion. I
include a DIV area on the page in which I set the style="visibility: hidden;
position: absolute; top: 40%; left: 40%". Then in javascript I simply grab
the DIV as an object by its ID and:

var theDiv = document.getElementById('divHidden');
theDiv .style.visibility = "visible";

The once-hidden DIV shows up over top of the previously visible page.
But I am certainly missing some steps.
I don't know how to "disable" the now underlying page nor "blur" it with the
smoke effect.

Smoke and Mirrors I suppose :-)

If I can get a similar effect in VS 2005, for now that would be preferable.

Thanks for any help with this...
