• Game Technologies: DirectX, XNA, XACT, etc. Sprite is not transparent

  Ok I finally got the game to work but I have a new problem...my texture which I made transparent in DirectX, doesn't have the transparent background when I run it. Is this due to my graphics card & me adding that line of code to make the program work Sorry I can't remember the exact line but it's been floating around the forums, I think we all know what it is. This is how I got transparent textures to work... Use the DirectX Texture tool and create a new texture the same size as your sprite. Now import your sprite into that layer. Now create a new sprite that is black and white. White is what is visible and black is transparent. and load unto alpha layer. Save it into one dds file and load it.. ...Show All

• SQL Server Regarding DataMining in SQL Server 2005 Analysis Services

  Hi to all I have a complex scenario , so first I want to ask out the feasibility of it . I think its better if I state the scenario and some one on this forum reply to it , I need to build an application (e.g credit card application , Loan Application etc ) that requires some approval from expert , what I firstly want is that I apply datamining on this data so that next time when I enter the data the result (approval or reject ) should be given by datamining tool , this I gather is poosible by using Analysis Services in SQL 2005 , but I also want the bases of that decision ( I mean the rules/some thing else  that the Datamining created agaisnt the data entered ) , So can any one do any ...Show All

• Silverlight (formerly WPF/E) Custom Controls

  So how can we build custom controls and deploy with the application I don't see anything that hints about how to include a referenced assembly that contains custom controls. I don't see any installable modules, or anything in the architecture that hints that it can be extended with custom controls, data binding, or .net-based event handlers. Thank you for using WPF/E. I am sorry to say that in Current CTP release we don’t support referencing an external assembly and data binding. In-fact, current version of WPF/E is a subset of WPF and does not support all the features of WPF. If you can share us what you are trying to do, May be we can help you with alternative approaches ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Engine Renderer

  I have been using an engine renderer that using DirectX 9.0c. It comes in a version that was developed in C Sharp, and I was wondering if that can be used with XNA Game Studio Express for the making of Windows and Xbox 360 games (assuming that XNA Creator's Club Subscription is purchased) I suspect that TorqueX will be a developer only licensing. So you buy one copy and then you can redistribute a run time or something. None of the other Torque products have any runtime licensing. So Developer (PC Only) - free XNA + TorqueX Friends to play (PC Only) - free XNA + free TorqueX redist Developer (360) - Creators Club + TorqueX Friends to play (360) - Creators club + free TorqueX redist Yes ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. .X features supported in XNA?

  Hi, I'm currently working on a .x exporter for XSI with shader support. However I have some questions regarding exactly what features are supported in XNA. Setting the technique in the .x file does not seem to work: EffectParamDWord { "technique"; 3; } XNA always renders using the first technique in the shader, unless you manually set it with Effect.CurrentTechnique :( Also what part and version of DXSAS is supported It would be nice if semantics used in e.g. FxComposer just worked with XNA, e.g things like: float4x4 WorldIT : WorldInverseTranspose; float4x4 WorldViewProj : WorldViewProjection; float4x4 World : World ; float4x4 ViewI : ViewInverse ; Or do you have to manually parse all effect param ...Show All

• Visual Studio 2008 (Pre-release) Media Element Will Not Play.

  I tracked the error down with the on failed error, and I THINK this is ther error: Insufficient memory to continue the execution of the program. I can only say think so because the routed events confuse me somewhat. I'm beginning to think my installation is hosed somehow. I'm not sure how that is though. I restored my laptop to factory configuration yesterday, installed vs, .net 3.0, .net3.0 sdk, orcas in that order. Then I immediately began working on my project and experiencing ide crashes. The orcas designer changes i mentioned in another post have come back, expression crashes upon closing the welcome screen. I cant tell whether my media element not playing is my fault or related to my hosed installation. Can you give me any ins ...Show All
