I am having difficulty loading a raw 24-bit RGB texture data from inside a file which contains other data. My idea is that I create a DDS file in system memory, load in the RGB data, and the use the D3DXCreateTextureFromFileInMemoryEx() function to create a mip-mapped texture from it. As far as I can tell, the DDS header is correct, but D3DXCreateTextureFromFileInMemoryEx() keeps failing. Here's my code:

Code:

Thanks for any help. Sorry about the formatting of my source - it didn't seem to work.

Not to worry, I have found my error:

Code: 
 DDS_HEADER *pHeaderDDS((DDS_HEADER *)(pFileDDS+sizeof(DWORD)));

It works now.
