DirectDraw 9?

It isn''t really DirectDraw... It is just a way of using D3D to do a 2D looking scene. There are tons of tutorials and samples on the web, just try google...

No. The DirectDraw exposed in Managed DirectX is a managed wrapper around DirectDraw7. There are no updates to DD7, the wrapper is provided since it''s the only way to expose DD to Managed DX users.

Converting any non-managed code to managed should be fairly trivial. And there are plenty of tutorials and books available on DirectDraw.

Well that''s not too good. I heard DDs use is frowned upon because it''s dated. That was the only thing that wasn''t very slow for C# or any thing .net for that matter.

How much people actually use it nowadays?

Eh, maybe a little. What''s more important is that most modern graphics cards are highly geared towards doing 3D accleration, not 2D acceleration (yes, you could get ''2D accelerator'' cards at one time). Plus, DirectDraw''s featureset is pretty pathetic compared to Direct3D - it can''t even rotate/scale your sprites.

Unless you''re comparing it with other 2D-only things (like GDI+) then that''s definitely not true; under C#, Direct3D runs at about 95%-98% the speed it does under C++.

Most people use Direct3D with Textured Quads or ID3DXSprite, as explained in the Forum FAQ. One might use DirectDraw if one wanted to support really quite old hardware.

Rich is referring to DirectX9 as a whole. There is no DirectDraw9, there is only DirectDraw7 and lower. If you are not using Managed code, the only way to access DirectDraw is by using the DX7 interface or older.

The DirectDraw exposed by .Net is merely a wrapper around the DX7 interface. It it not a DX9 interface. It was included in the DX9 package because there was no version of Managed DX before 9, so they exposed the DX7 interface.

Hopefully I''ve stated the same thing in enough different ways that it makes sense to everyone.
