• Game Technologies: DirectX, XNA, XACT, etc. retrieving data from gamecomponents

  Hi all. I'm hoping someone can point my confused self at the (probably simple) solution to my problem. The only way I can find to access information from added components (Components.Add(myCoolComponent);) is to create myCoolComponent as a 'global' object in my main game. I wouldn't feel so bad, though it _seems_ like a good way to use up RAM, but if I need to find myCoolComponent.position in an instance of a class I'm forced to pass the original copy of myCoolComponent around all the time; and that can't be good. What I imagine I'm looking for is something like: game.Components.myCoolComponent.position. //confused! You could consider publishing a service from your component ... if ...Show All

• Visual Studio 2008 (Pre-release) How DLINQ Track Changes

  Would like to know how DLINQ track changes. a bit confused after play around a bit. What im trying to do is to keep a Table in memory for updates. changes are only submitted to DB when necessary. but my updates need to be viewed/requested before submit to DB. it is something like memory table. The esiest way i thought is to use Table < M yTrack > , but when i tried it, i can't see the changes reflected locally unless i do db.SubmitChanges() I have tried to use private List < MyTrack > myData; myData = db.MyTracks.ToList(); with this, i have no problem to do any updates and see the changes locally without affect the DB. but in this way, i have write my own SubmitChanges as i need to map List < MyTrack > ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Problem creating a render target.

  I'm just having issues because I'm trying to create a render target with a surface format of RGBA5551 is it unsupported With SurfaceFormat.Color it doesn't raise an exception, so I'm guessing it has to do with that. Surface renderTarget = this.graphics.GraphicsDevice.CreateRenderTarget( 1024, 512, SurfaceFormat.Bgra5551, MultiSampleType.FourSamples, 0, true); Am I doing something wrong here do I need to prepare the device first I don't think it's that my vidcard doesn't support it since it's a Geforce 7800GT... Well, any answer would be greatly appreciated. Neither nVidia nor ATI hardware supports everything. That’s the reason why Direct3D 9 ...Show All

• .NET Development How to bubble exception from background thread to main thread?

  Hi, I'm having a problem with background tread throwing unhandled exception and it never bubbles up to main thread. I have been told to put background thead into try catch block but this still does not work as it's never get's hit. My code is below. I did not think it'll ever come to this but I really want my main thread and application to crash so I can see error being thrown by background thread. try { this .backgroundWorker1.RunWorkerAsync( ); } catch ( Exception ) { throw ;} You misunderstood me. The exception handler should be in the function which runs on the other thread. You are doing this in the UI thread, which leaves the try block quite fast. You never spoke of the Backgrou ...Show All

• Internet Explorer Development bypass or supress print dialog box

  Hi! I'm developing this web aplication for an intranet where the user can print a list, I want this to be automatic, I know I can do so by using a java script, but then I was asked to avoid the browser to show the printer dialog box so the printing process would be much more faster and easier for the user; I found some info about this in a forum ( http://www.codingforums.com/archive/index.php t-224.html ) and I understand that acording to this site what I want could be posible in former os and ie versions but not in the new ones with updates (and I understand why). My cuestion is; Is it true that supressing or bypassing the printer dialog box by an script isn't posible and if so maybe someone can point me out to a ms oficial article rel ...Show All

• Visual Studio Index of MSDN for Visual Studio 2005 incomplete

  Hi, Recently I found that the index of my MSDN for Visual Studio 2005 was incomplete. I typed in "LoadTypeLib" in the index, but only the result for Window CE 5.0 was found. At first I thought this function was cut off (!) in Microsoft's favor of .NET, but after comparing with the result of MSDN for Visual Studio 2003, it turned out that it was still under "Win32 and COM Development -> Component Development -> Automation -> SDK Documentation -> Type Description Interfaces -> Overview of Type Compilation and Library Functions". I also saw the document content for this unindexed function started with a weird hollow black box, and it was the same with some other unindexed items. I tried what Mike C ...Show All
