I'm writing an animation app in C#/WinForms (see this question). Basically, the animation in my application is smooth but shows tearing effects; when I take the same animation and render it to an AVI file and play it with Windows Media Player, the animation shows no tearing effects at all. I know WMP is not changing the frame rate beca...

I'm currently using the following code (C#): private static void PlayLoop(string filename) { Audio player = new Audio(filename); player.Play(); while (player.Playing) { if (player.CurrentPosition >= player.Duration) { player.SeekCurrentPosition(0, SeekPositi...
This is kind of a COM question to do with DirectX. So, both ID3DXSprite and ID3DXFont and a bunch of the other ID3DX* objects require you to call OnLostDevice() when the d3d device is lost AND OnResetDevice() when the device is reset. What I want to do is maintain an array of all ID3DX* objects and simply call OnResetDevice() and OnLos...
I am using SlimDX with WinForms for a while now, but want to make the switch to WPF now. However, I can't figure out how to get DX10/11 working with WPF. The February release of SlimDX provides a WPF example, which only works with DX 9 though. I found the following solution: http://jmorrill.hjtcentral.com/Home/tabid/428/EntryId/437/Dire...
I'm using D3DXSaveSurfaceToFile to save windowed Direct3D 9 surfaces to PNG, BMP and JPG files. There are no errors returned from the D3DXSaveSurfaceToFile call and all files open fine in Windows Photo Viewer and Paint. But they will not open in a higher end image editing program such as Paint Shop Pro or Photoshop. The error messages...

hi, I'm experiencing with shaders a bit and I keep getting this weird compilation error that's driving me crazy! the following pixel shader code snippet: DirectionVector = normalize(f3LightPosition[i] - PixelPos); LightVec = PixelNormal - DirectionVector; // Get the light strenght factor ...
Hello, I'm writing an open source 2D game engine, and I want to support as many devices and platforms as possible. I currently only have Windows Mobile though. I'm rendering using DirectX Mobile, with DirectDraw as a fallback path. However, I've run into a bit of trouble. It seems that while the reference driver supports createRenderTa...
Hi All, We recently upgraded from 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 d...
Using the D3DX library that is a part of directX, specifically directx9 in this case, I'm wondering if it's safe to use the same matrix (or vector etc) for input and ouput D3DXMATRIX mat; D3DXMatrixInverse(&mat, NULL, &mat); I've been avoiding doing so, assuming that it would result in bad things happening when parts of the array got ...
C# programmer, beginner DirectX. Have created 2 meshes using Mesh.Cylinder but need to combine them into a single mesh. Is that possible? ...
I actually just have a rather small question, but I have had the HARDEST time finding information about it. For the application I am programming for, there will be a 3-axis joystick being connected via USB to a Windows XP computer, and it is being handled by directx. That information will then be sent elsewhere to an embedded controlle...

I am using Microsoft Visual Studio 2008 and have installed Windows Mobile SDK Standard and Professional refresh. The device is correctl...
I have a Mesh object returned from Mesh::TextFromFont and I am trying to set the color of each vertex. I am calling the vertex buffer's Lock function like this: mesh->VertexBuffer->Lock(0, LockFlags::None); However, this call throws an exception. Another overload of Lock seems to work fine, however it requires me to pass the rank of th...
Is the format of compiled pixel and vertex shader object files as produced by fxc.exe documented anywhere either officially or unofficially? I'd like to be able to read the constant name to register assignments from the shader files. I know that the effects framework in D3DX can do this, but I need to avoid using D3DX as it may not be i...
I have a WPF application which has a DirectX component within it. This component does not work over Remote Desktop--it just shows a corrupted image. The application works fine when not using Remote Desktop. In trying to debug the problem I installed the February 2010 DirectX SDK. Now, when I run the program on the computer with the SDK ...
