Tricks with D3DX10GetImageInfoFromResource
I am playing with D3D10 tonight, and I am trying to get D3DX10GetImageInfoFromResource to work for me. I have beaten on it for a long time, and it still resists my powers.
On a whim I write some code to call FindResource myself to make sure that I can find the resource and it works, but that makes me think about the resource types on this page:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/WindowsUserInterface/Resources/IntroductiontoResources/resourcereference/resourcetypes.asp
And then I remember that some other D3D resource functions like resources to be in RC_RCDATA format. Lo and behold, this is the problem - I had a bmp file as a resource, but it was marked with RC_BITMAP!
Lesson learned - D3D loads RC_RCDATA resources, even when they are bitmaps. I hope this saves somebody some time one day :)
