DirectX Overlay DLL for use with C#

I need the ability to display a windows form, or rather, the image of a windows form on top of a windowed or fullscreen DirectX game. The image shown needs to be updatable - not a fixed "image" as in some examples on the net I already have a C++ example that does exactly what is required, but I do not understand enough c++, nor have the time to learn, to convert the "exe" example, into a DLL I can then access from C#. This example is attached to this post. Basically, if you can create a dll that I can pass a windows form to, and it gets displayed as an "overlay", exactly as in this example, I'll be happy :) Preferably, I would like the DLL to be written in C#. If not, then the code should be very well documented, as I will like to learn from it. Minimum requirement is that the overlay MUST appear over the "Battlefield 2" and "Battlefield 2142" games released by "Electronic Arts". I can provide a copy of either of these games for testing purposes if needed. If you have any questions regarding this, please email me as I'll be happy to discuss it. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
