Direct3D 11 example in BB4W

OK, the reality is not quite as exciting as the subject line suggests: all the program below does is to clear the window to a uniform dark blue colour. But it is genuine Direct3D 11 code, and it could form the basis of greater things. To my absolute astonishment it ran first time (once typos had been corrected):

What I propose to do, if there is sufficient interest, is to publish a series of Direct3D 11 articles (based directly on the Microsoft tutorials, as this code was) on the BB4W Wiki. I realise that some people might prefer Direct3D 12, but very few users currently have that and it's difficult to find good tutorials to plagiarise adapt!
Thoughts?
Richard.

Has the Rubicon been crossed 
Yes that would be good
Re Directx12 Documentation https://msdn.microsoft.com/en-us/library/windows/desktop/dn899121(v=vs.85).aspx
samples
[urlhttps://msdn.microsoft.com/en-us/library/windows/desktop/mt186620(v=vs.85).aspx][/url]
Nvidia currently only have native driver support for there latest graphics cards . I have the previous chipset which at present is not support for dx12 feature boo. and is coming soon. In any case having support would beat many others to the punch.
Im also interested in process you take Richard to bridge the link between the DLL and a basic library/code
Also was that utility to extract header reading the DLL directly or a C++ header file source code?

I know it's documented, but there are not (as yet) any Microsoft tutorials - starting with something simple and working up to more complicated tasks - similar to those for DirectX 11.

I'm translating the C code in the tutorials to BASIC. It's largely a 'mechanical' process but not one that it's practical to automate, so quite tedious and time-consuming. I've yet to discover what issues the later tutorials may raise.

It scans D3D9.H (header file) and I've now written a similar one to scan D3D11.H.

I have all the libraries needed at the moment. Of course, they could probably be updated.
If there is sufficient interest I could upload them.

You said in another thread: "I only have a 'starter file', basically getting a device going" so it would seem that in fact you didn't even get as far as the degree of functionality in the code that I posted this morning. That may not do much, but at least there's something to see!
What I am specifically doing is translating the Microsoft tutorials (there are others out there, but they seem to take bigger steps and in some cases you need to pay a subscription before you get to the end!). When I eventually put the code on the Wiki I want to be able to cross-reference those tutorials, where there is much more detail.
In any case I want to understand this stuff to a degree that I can provide support to other users, and there's no better way than doing it myself.
So thanks, but no thanks.
Richard.

Making good progress: today I've managed to get Tutorial 2 running (admittedly it didn't work first time). The code is too long to list here (and needs to be tidied up before public consumption) but as evidence here is a rendered triangle. I know it's not rocket science, but it takes nearly 300 lines of code to achieve it in DirectX 11!
Edit: I should add that I've departed from the tutorial code slightly in order to avoid the D3DX issue. I'm using the D3DCompiler DLL, which comes as standard with Windows 8.1/10 and which is in any case legally redistributable.
Richard.

Have the direct x 11 tutorials code been uiploaded some where?
The Directx11 header files? Library?
