directx

In the past I have created DirectX applications in the C++ programming language, however, I would like to know if it is possible to do this using the C programming language. Thanks. Yes it is possible. DirectX exposes a COM interface and C is capable of consuming them. It won't be a whole boat load of fun though! The Open Watcom C/C++ compiler comes with DirectX sample applications in both C++ and C. Both work. They are under WATCOM\samples\directx\cpp and WATCOM\samples\directx\c respectively in OW 1.9. This is what the code looks like in C++: hr = d3d->GetDeviceCaps(D3DADAPTER_DEFAULT,

I'm trying to create a vector for D3DXMATRIXA16 like so: vector<D3DXMATRIXA16> matrices; and am getting the error: d:\Program Files\Microsoft Visual Studio 9.0\VC\include\vector(717) : error C2719: '_Val': formal parameter with __declspec(align('16')) won't be aligned e:\projects\emuntitled\em\emscratch\emshadow.h(60) : :see reference to class template instantiation 'std::vector<_Ty>' being compiled with [ _Ty=D3DXMATRIXA16 ] Why is that exactly? Thanks for any help! It is a known issue [link dead] that stl::vector cannot properly contain aligned data, such as D3DXMATRIXA16. One poster pinned

I got into a little trouble sending keys. It seems like when ever I want to send keys It doesn't work. I'm thinking about sending alphabetic characters such as T to bring the chat up from example, but If I write It to the enum, nothing happens whenever I use them. Any ideas? [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)] public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); [DllImport("user32.dll", SetLastError = true)] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); /// <summary> /// Virtual Keys /// <

We recently upgraded from VS 2005 to VS 2008 (Windows XP). We use SlimDx in one of our projects. All was working ok after the upgrade, except my Recover function, which gets called on devicelost/device reset which crashes with D3DERR_INVALIDCALL: Invalid call (-2005530516) I use Ctrl - Alt - Del and then Escape to simulate device lost. void Recover() { try { if (res.Code == D3DERR_DEVICENOTRESET) { res = m_device.Reset(m_presentParams); //Crashes on this. if (res.IsSuccess) { m_deviceLost = false; } } } catch(Exception e) {} } Is this something to do with VS 2008 , as it used to work nicely

This is my first question ever on StackOverflow, hurray! I can honestly say I use StackOverflow on daily basis for both my work and personal programming mysteries. 99,9% of the time I actually find the answer I need on here too, which is great! My current problem actually stumped me a little as I can't seem to find anything which actually works. I've already read several posts on GameDev.net and found other resources around the net but can't sort it out. I am in the process of porting a small 2D engine I wrote for XNA to SlimDX (just DirectX9 at the moment), which has been a good move as I
