• Visual Studio 2008 (Pre-release) Distance between 3d objects / world coordinates of a model3DGroup

  Hi all, Newbie coder I'm afraid, but this should be a simlpe one to answer. I don't have a good grip of 3d in WPF yet, so patience would be appreciated. I have a carousel-like control in WPF. In a viewport 3d, I have a Model3DGroup, m3dMainGroup , which contains another m3dModel3DGroup. Now transformations are applied to both of these Model3DGroups. All I want to do is work out the distance along the PerspectiveCamera's lookdirection to each of the Model3Ds in m3dModel3DGroup. All I need to do in theory is get the Vector3Ds in my Viewport's world-space to the Camera, (a) model, and the Camera's look direction. Then the distance would be just ( LookDirection . ( Camera - Model ))/| LookDirection | Code rather than XA ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Object cache vs. GameComponentCollection

  Can anyone tell if the GameComponentCollection is designed to simplify game object cache requirements I noticed that the space wars example seems to override this with screen.Render(). If it is supposed to, are there any forseeable performance impications I don't believe so. GameComponentCollection is just a collection of GameComponent classes - it has no special functionality of game object or resource caching. The reason you saw the screen.Render() override is because space wars uses a component to swap in different game "screens" - the main menu, the play space, etc. It doesn't really do any caching in itself - the screen component seems to act as a container for the rendering code, making it easier to swap in and ou ...Show All

• SQL Server I need help with xmla query

  Hi, I need to do a xmla query for calling more than one prespective. For example: I have a cube with 4 perspectives, but in the xmla query only need 2 perspectives. Cube: Censo Perspectives: Depto. Pais Principal Privado But i only need Cube: Censo Perspectives: Depto Pais Thanks for the example, now I understand what your are after. :) Unfortunately I don't think you can have more than one CUBE_NAME element in your restriction list. What I believe is happening is that the value is being overwritten and the last one is the one that is used. I think you have 2 options 1) fire off 2 separate Discover requests, one for each perspective 2) do not put any re ...Show All

• Visual Studio 2008 (Pre-release) DataTemplate with custom control problem

  I am using WinFX beta 2 on XP sp 2 cz. I am writing ViewerEditor custom control derived from Border(Decorator) which is used in DataTemplate of ListBox/ListView item. The ViewerEditor.Child is set to a data viewer (say TextBlock) data bound to item data. ViewerEditor.Editor is set to a data editor (say TextBox) data bound to the same item data. When specified action ocurres (say mouse click on focused ViewerEditor), ViewerEditor adds ViewerEditor.Editor to its AdornerLayer through custom EditorAdorner. The problem is when I add ViewerEditor to the DataTemplate and run my sample, it throws this exception: Error at element 'TextBlock' in markup file 'Db4o.Binding.WPF.Tests;component/testwindow.xaml' : '3_T' name not valid for identi ...Show All

• Visual Studio 2008 (Pre-release) Up/Down keys in Gridview sends focus to next element

  Working with a Gridview we are seeing behavior where if you are on the bottom row of the GridView and hit the down arrow key, it will send focus to the next control. Same with the top row, it goes to the previous control. Is there any way to avoid this Typically in a grid type control in this situation, it would do nothing. At least, that's what our users are used to. With the default ListView with GridView keyboard navigation should be contained within the list. You can also customize the behavior by setting KeyboardNavigation.DirectionalNavigation on the ListView or items within. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Issue with HowTo: Rotate and Move a Camera?

  I'm trying to work on figuring out some simple camera manipulation and have been going through the information on the How To: Rotate and Move a Camera. At the bottom of the help file is what appears to be the complete code needed to run the example. However, this code does not compile when pasted in a new project; the method FrameRender() refers to an undefined method called UpdateCamera(). Is this method something missing from the example Hi Shane, Sorry about the confusion, the UpdateCamera method was unintentionally stripped from the source code and will be in the next release. The UpdateCamera method is almost identical to the UpdateCameraFirstPerson method without an offset from the avatar's position. I've copied the ...Show All

• Visual Studio Sandcastle and IDL Files

  http://blogs.msdn.com/sandcastle/archive/2006/08/13/697859.aspx#comments States the following: "We are currently looking at the naming convention and will probably rename MRefBuilder to Mreflector for Sandcastle RTW . We also expect the Sandcastle reflection data format to be targeted not only by MReflector , but also by unmanaged reflection tools (for example, a UReflector tool that parses IDL or header files) and SReflector (for generating schema documentation). In order to make it easier for other to target the reflection data format, we plan to supply an XML schema file that defines the format."
