• Game Technologies: DirectX, XNA, XACT, etc. Drawing colored meshes using own effect

  I want this easy thing to work -- but apparantly it's not that easy for me. I simply want to load a colored mesh from a file, and draw it on my screen using a custom effect. The mesh(es) load just fine in DXViewer, and also no problem when I'm using the BasicEffect to draw the mesh. The mesh is drawn at the correct position/scale, but the colors are wrong. They seem to be random, and sometimes they change during runtime. I've posted the relevant XNA code below. Of course it's incredibly rediculous to put all this code in the Draw method, but it's just to show you all the relevant code together. So here we go: protected override void Draw( GameTime gameTime) { CompiledEffect compiledEffect = Effect .CompileEffectFr ...Show All

• Visual C# Math: Round up number. eg 1234 / 50 = 6

Therfore i need to know how many pages i will need to for my data Eg, i have 1234 rows of data and each page will contain 50 rows. So 1234 / 50 = 24.68. So I need 25 pages How do i round up a number so 1234 / 50 = 25 . Thanks. Paul in this particular scenario, we would want a double division and not the truncating remainder behavior of integer division. my procedure also works and that is just my point. a Ceiling call after division obviously did not work because of integer division so one can use double division instead. there are a number of ways to solve the poster's problem and mine is just one of them, and so are the o ...Show All

• Visual Studio Team System Who wants a FxCop VS2005 add-in?

  Hello, I have written a simple add-in for VS 2005 to enhance integration with the IDE for those who are not using the Team System version of the product.
