If you haven't tried out DesktopX 2, you should. I haven't enjoyed skinning and such this much since the WindowBlinds .39 days. 

Today I figured out how to embed flash.  believe it or not, you can actually embed the flash .swf file right into a .dxpack itself (.dxpack is just a .zip file renamed) and distribute the flash file directly.

But I'm also having fun having it point to websites that have flash.

Here's some typical code:

So I put that on the web page.

First line get rid of the scrollbar and margins.

Then I have the width and height changed to 100% / 100% since Flash can scale on the fly which is nice.

Then I create my DX object, create a script and have it be an ActiveX control that points to my HTML file.

I tell ya, Flash and DesktopX are like two pees in a pod.
