I found this page speaking about DirectX user control:
http://msdn.microsoft.com/en-us/library/bb153289(v=vs.85).aspx
I download several DirectX SDK and the code should be here but I can’t find it:
(SDK root)\Samples\Managed\Direct3D\CustomUI
Does someone have an idea where I can download these samples?
Found in DirectX SDK april 2007.
