My program won't close after I call X3DAudioCalculate, is there something I need to do before closing my program? I can't delete pMatrixCoefficients of the DSPSettings structure so I'm guessing there is something I need to do to free the memory X3DAudio is using but I don't know how and I can't seem to find any documentation ...

They don't seem to care about stuff like that, I reported a bug in the ID3DX10Mesh interface that gives a 64 Kb memory leak after you release the mesh but I've not heard back from them. I have also reported countless bugs in the DXUT.

Well I need to use the red channel of an array of DWORDs as the Alpha for a texture. I got some ASM code that flips the bytes but I don't think this is the best way to do this, so how should I do it?

Yeah I just made my own because I noticed that as well...

I need to draw a sprite with alpha but I don't know how and I Googled it and found little if any useful information.

Ok I did what you said and it works but I have 2 last things I need help with. I am not sure what you mean by "5) select the font into a physical DC (to enable anti-aliasing)" and the other problem is that the text is upside down, how can I flip it? Here is what I have so far:     RECT rect;    ...

Well I was trying to create a texture from memory that I can use for a sprite but I'm getting an access violation on CreateShaderResourceView, here is my source: DWORD* pSrcData = 0; RECT rect; // ...Set pSrcData and the rect to my image. ID3D10Resource * pTexture; D3DX10_IMAGE_LOAD_INFO info; info.Width = ...

If I could find a diagram on how ID3DX10Font works then I'd know what I need to do.

Is there a way I can get an hDC from the devices back buffer?

how?
