Draw Debug Information

If by debug information you mean arbitrary information you record, you can easily do that using ID3DXFont. If you mean the 'debug spew' you get from Direct3D, then there's no easy way to do that, AFAIK.

Thank you for your reply!

Other than "String", if I wanna draw a rectangle, circle, or line on a directx handled screen, what can I do?

You might well have to handle this yourself - I don't think D3DX will help you with 2D primitives (it does have some stock 3D ones though). If you create a list of 4 verticies as a "line list" you can draw a square/rectangle. Circles are similar, but require a bit more work using trig functions..

One other idea that I use a fair bit in my engine... If you mostly need text output rather than "integrated" graphical debug then you can stream it to a secondary window.. When you want to debug your game/engine, run it in windowed mode and with some suitable resizing you can watch whats happening in the other window. This also works a charm in a dual-monitor setup.

Since quality isn't a high priority in a case like this, a simple circle sprite should work well. Just scale it as needed.
