DirectX Texturing a Quad problem

[phantompig]

Hi

I am trying to adapt a Quad class to have texture mapping rather than just vertex colour. I have tried numerous approaches but the only output is a black quad on screen. Any suggestions would be greatly appreciated.

The vertex format has been changed to have a U and V co-ordinate so ignore any reference to colour as this was used in the previous format. Area's commented out were my attempts to map the texture to a single quad. The ideal aim is to specify a large quad made of several smaller ones and use the delta value to set thier U,V values.

Hope this is clear, the .h and .cpp are included below. If anything else is needed then let me know.

Thanks
