• Game Technologies: DirectX, XNA, XACT, etc. Trouble using Asteroid Models

  I'm trying to use the asteroid model from the SpaceWar template, but when I try and render the model, it comes out being mostly transparent. I've copied all the content over from SpaceWar, but it still doesn't work. I used almost the exact same code on one of the spaceships, and it worked fine.

• SQL Server SSIS and the Receive Command

  I built a system where I am sending batches of messages using a single conversation. I want to pull these messages out of my queue using Service Broker. I may have more than one batch sitting in the queue waiting to be picked up, so.... In my SSIS package i started by getting a unique list of conversation_handles where the message type is my end of batch message ( should only be one per batch). Then I used the foreach loop construct thinking I could pass the conversation_handles around and into the data flow. In the data flow I want to pull all of the messages at once. It looks like the receive statement is designed to do this with the concept of using a table variable. So I built this SQL to use in for the SQL Command of my OLE ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Problem rendering with vertex buffer

  Hi, I'm trying to draw a textured square to the screen using ManagedDX 1.1. Unfortunately, the DrawPrimitives call is giving me an exception, but all the error message says is "Error in the application" which is not very helpful. I really have no idea what is wrong, because this was working before and it's stopped working when I was reorganizing the code in my classes. I've pasted the two functions which I think are relevant, if anyone has any suggestions I would greatly appreciate it. (also, the code below seems like a terrible way to update the data in the vertex buffer, if anyone could point me to a "more correct" way of doing things that would be good too :) public override void Draw( Point dest_pt) ...Show All
