In going through your tutorials lessons 7 through 9 only display a blank black window on my computer, lessons 1 through 6 and lesson 10 work correctly. Anything I'm doing wrong?

Hi Colin,
I suspect that the functions from the D3DX9DLL are not being loaded but could you report back?
** Now, with the last file (D3DX8BBC.dll) RENAME IT TO D3DX9BBC.dll ** (and make sure it is in the @lib$/Directx9 folder
Thanks for the report back. I will update and include some more error reporting to check that all the functions are installed properly.
Have you any other comments or critisisms...? I do find I will get something working this end and not think of little things to make life easier for other users. So if you have any suggestions I would value them.
Michael

No no no no no! Don't do that - D3DX8BBC.DLL is not compatible with DirectX9.

I know, I know. I've just hit CreateTextureFromFileA% where you have to pass the device pointer as the first parameter. The maths functions work but obviously not these functions. I am now dedicating my time to creating the real D3DX9BBC.DLL...

What is the situation with using directx9 via the BBClibs?
With directx12 on horizon is that going to be quite different?

The existing D3DLIB library uses DirectX8 rather than DirectX9. There's a particularly important reason for that, which involves the Direct 3D Extensions 'D3DX'. Microsoft permits the distribution of the relevant DirectX8 DLL with applications (supplied as standard with BB4W as D3DX8BBC.DLL) but they do not allow the distribution of the D3DX9 DLL on its own. This makes it almost impossible to support DirectX9 legally from BB4W without shipping a massive MS installer at the same time.
To date, each new version of DirectX has been backwards-compatible with earlier versions, so DirectX8 code (and therefore programs using D3DLIB) still run fine on the latest versions of Windows. If this situation changes, and DirectX8 support is withdrawn by Microsoft, then something would need to be done to maintain D3DLIB functionality.
Of course you can use DirectX9 from BB4W, so long as you avoid the D3DX extensions library entirely, or rely on it already being installed on the target PC (tricky, because there are many versions), or distribute it 'illegally'. Before Michael Hutton 'jumped ship' to PureBasic he wrote a number of DirectX9 applications, proving that it's possible within those restrictions (see earlier posts in this thread).
So, I don't currently have any plans to update D3DLIB but I would be interested to know if there is a demand for this. I haven't investigated whether DirectX versions later than 9 resolve the DLL issue, or make it even more problematic.
Edit: Checking what files are on my PC - d3dx9_32.dll, d3dx10_42.dll and d3dx11_43.dll - those pesky version numbers strongly suggest that the problem is not eased in DirectX 10 or 11.

Thanks for that.
After reading this it might not be a big deal

Arguably, the biggest disadvantage of working with DirectX8 rather than DirectX9 is the lack of documentation (other than that supplied with BB4W). Much of what used to be available online seems to have disappeared (I've not tried searching the web archive).
Unfortunately it appears that Michael Hutton has deleted his BB4W DirectX9 tutorial, and its support files, (referred to earlier in this thread) from the Yahoo group.

They were based on http://www.directxtutorial.com/default.aspx
but crucially it requires your DLL wrappers to support it . Are those Dlls opensource?

Those tutorials look quite interesting (particularly the DirectX 9 one) although much of the earlier material - what they describe as Direct3D Basics - is covered in the BB4W documentation or the various example programs.
It's the more advanced stuff - like meshes, sprites and HLSL programming - that could be of particular relevance to us, but unfortunately that's only accessible by paying $50 for 'premium membership'!

Unlike DirectX 8, for which documentation was hard to find, there are many web sites with tutorials and other information on DirectX 9, and most importantly MSDN itself still covers Direct3D 9 in detail.
Specifically, when using the new BB4W libraries, the value returned from FN_init3d() is a pointer to an IDirect3DDevice9 interface. Would it be helpful for me to produce an appropriate BB4W structure declaration for this interface?
Is anybody going to take the bait and write some 3D code?

You didn't answer the question about whether a Direct3DDevice9 structure declaration would be useful. It's not a trivial thing to generate (there are an awful lot of methods to include) so I'd like to know that the effort wouldn't be wasted.
