• Game Technologies: DirectX, XNA, XACT, etc. Whos using TorqueX, Who isn't?

  Just curious: 1. Are you using TorqueX or not - and why or why not 2. If you are using TorqueX are you also using TorqueX Game Builder and why or why not I'm experimenting with both but haven't decided if its the way I'm going to go yet. I'm not using TorqueX yet, but it is something I plan on looking at at some point, just to see what's it's all about. I'm not really planning on using it regularly. Being able to make my 2D games so rapidly with XNA is already so impressive for me, I'm not sure I would be able to handle the shock to my system to see it made even easier. So I'm not using TorqueX so that I live longer. ...Show All

• Visual Studio 2008 (Pre-release) Extending DataContext?

  Is it or will it be possible to override the internals of the DataContext I want to alter the object creation implementation in the datacontext to create subclass proxies instead of just instancing the entity types directly. However DataContext seems very black boxish. Im well aware of the claims that non virtuals execute faster than virtual methods etc.. but in this kind of scenario where big chunks of data is fetched from some sort of datasource , those few nano seconds will be impossible to notice.. so that will hardly be a valid argument. Ive seen that there is a "services" collection inside the datacontext , but that also seems impossible to access from the outside. it would be really really lovely if such things were expo ...Show All

• Visual C# Calling methods of a class without creating an instance of it

  Hi, I'm sure this probably has been answered before, but somehow I couldn't find it, so really sorry about that. But how do you call methods of a class without having to create an instance of it I mean, in my project I have something like: public class FileOperations{ public void read_config_file(...) { (...) } } And I want to call the read_config_file(who doesn't depend on anything but the filename and a property where it'll write the config values) without having to do: FileOperations fileOp = new FileOperations(); fileOp.read_config_file(); I was a poor (poor like in noob) Java programmer but I used humm I believe it were static methods in abstract classes, something like that, don't re ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Two gfx-cards in parallel ?

  Hello, i have a general question and hope somebody can give me an answer. Is it possible to run two instances of a D3D-programm on two different graphics-boards the same time The full-screen output of each program should be displayed on one monitor each - there should be two monitors connected to the two graphics-boards. The boards are two GF8800 GTX, built inside an SLI-Motherboard. Thanks, Enrico Zschau When SLI is active, DirectX recognizes them as one adapter. That's what SLI is for; using them in unison. I think you'd have to turn off SLI to do something like that. Also, one graphics card can handle multiple monitors on its own. ...Show All

• SQL Server Strict Transaction Nesting Bug with CLR

  Dear all, I am constantly running into this error when calling CLR functions from triggers (even when the triggers are CLR functions themselves): The context transaction which was active before entering user defined routine, trigger or aggregate "[name of CLR sp]" has been ended inside of it, which is not allowed. Change application logic to enforce strict transaction nesting. However, there is no cyclic nesting going on here. In fact, the error only appears when the CLR function is writing to the database. Only executing SELECT statements inside the statements doesn't freak out the SQL server (2005 SP1 in my case). I am not ending any transaction at all. This error shows up in many places: as exceptions from ASP.NET web pages, ...Show All

• Visual Basic MessageBox.Show doesn't works in Win2003 ED. Why?

  Hi everyone, Primary platform is Framework 2.0. We're suffering an odd behaviour for an UI code. We've built a Windows Service by means of VB and everything goes fine. OnStart method and another ones we've defined a MessageBox.Show function in order to show errors or whatever to the users but unfortunately they don't see at all. Curiously it happen only in our server (Windows 2003 Enterprise Edition) no in a Windows XP Pro workstation. Does anyone ever faced this issue According to BOL is not recommendable to show UI in that kind of projects but "only not recommendable". Thanks for your time, I think you'll find the issue is more to do with windows service than the OS - messagebox works ...Show All
