• Game Technologies: DirectX, XNA, XACT, etc. Custom Vertex Format

  I have been playing around with creating my own custom vertex formats in XNA. To test whether it works I am creating a vertex format that is the same as VertexPositionColor. I created a struct with a Position, Color and SizeInBytes property. Creating the vertex element array is also no problem. Until here my vertex format and that of VertexPositionColoris exactly the samen. The only thing that is different is what both return in the GetHashCode method. I believe this value is used to actually use it (in combination with the vertex element array to index this value). In the GetHashCode method I return: this.Position.GetHashCode() | this.Color.PackedValue.GetHashCode(); I got this from this article . Can anyone tell me what I am doing wrong ...Show All

• Visual Studio Team System Runtime error

  I have been working on the same project for the last few months with degree of success. However, every few days the client produces a new build for the application that sometime requires a complete re-script. During the latest build I decided to install SP1 for VSTE. Since then I have re-recorded the process and am now unable to play it back without displaying a 'RUNTIME ERROR', this happens on the first post back to the server, i'm not sure if this is due to the new build or the SP. Prevoius tests did not disply this message, however the latest has. i've tried the obvious hidden fields by extracting the manually (not relying on the automated code generated) this has made no difference. Time scales are very tight, I need this to work as so ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. GameComponents class inheritance

  Hi, Right now, when you add a GameComponent to your project, it inherits from the class GameComponent in Microsoft.Xna.Framework. In project that is fairly small or for giving components to other peoples, it works great. But I see a problem when you want to build components for a large scale engine. Let's take a Grid GameComponent as an exemple. This game component cannot inherits from any of the class that already exist in my engine simply because C# does not allow multiple inheritance. So, I cannot give the grid any of my scene graph functionality since that functionality is not built in inside GameComponent. I could use an interface to implement this but then I'll have to add the same code to every component. ...Show All

• Smart Device Development Microsoft Contacts Control

• Windows Forms cause a property to display "builder" button to browse for folder ?

  I'm writing a custom control. One of its properties is a directory name. I'd like the property sheet to display a "build" button that--when clicked, displays the standard Browse for Folder dialog. I have no idea how to do this. Any help getting started is appreciated. I don't know if you can call the folder browser directly, so you might need to research that some, but you can do what you want by: Creating a custom editor for your property derived from UITypeEditor (Look at help for this guy for a good sample) public override UITypeEditorEditStyle GetEditStyle(System.ComponentModel.
