I use scaleform sdk and development A8 dll support some times. The Scaleform is create hWnd and render swf use d3d9 API. It's on_message all input(keys) in swf and as3.

The structure:
1. init(all types and define)
2. render(swf in screen)
3. on message(input and event return)

And my questions:

The dll was done in C++, and test by main function.
I can't render GFX UI in A8 engine.
But I can use dll function create new hWnd and display.

Has anyone successfully tried it?
I want display GFX UI in A8 hWnd.
