• Game Technologies: DirectX, XNA, XACT, etc. Shader Problem (+video)

  Hi all, I seem to be having a slight problem with one of my shaders. See the video: http://luteo.us/wp-content/uploads/2007/01/ShaderError.mov As you can see, the transparency is not acting as it should. Though the transparent sphere I can see the tiger and the yellow globe but not the cylinder. I'll post the .fx file if you request it. Some more info: I'm building this all in C# 2005 (Std), using the latest DirectX SDK (December 06). Thanks in advance, Eddy This is not a problem with your shader. This is a Z buffer problem because you're sphere is renderer before the cylinder. The tiger and the globe are rendered after the sphere so there's no problem with them. Right ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. mp3 player

  I'm planing to make an mp3 player for the windows version of xna using lame or wmp(or if someone noes better ). just before i start what do you think the best method would be Do you think they will even work Unfortunately, XNA itself doesnt support any way of playing files other than those prebuilt using xact. You cant directly modify buffers or anything like that so using XNA for sound is probably completely out. You could use some 3rd party sound util (or DirectSound), but your not touching XNA with it. Also youd lose the ability to easily port to the 360 in future (which may or may not be an issue for you). You can however use XNA for some nice visualisations, and to make the 360 controller rumble t ...Show All

• .NET Development WSE 2 HTTP Compression

  Has anyone implemented WSE 2 with HTTP level compression using GZIP I have a web service that returns data in compressed format to improve performance but the WSE proxy does not let me extend the SoapWebResponse in proper fashion to decrypt incoming stream. I was able to do this with SoapHTTPClient. Explanation:I am able to request GZIP stream data from the server by overriding GetWebRequest (which is type of SoapWebRequest for WSE) but I can't decrypt the response since it's wrapped in SoapWebResponse. The SoapWebResponse does not allow direct access to the stream which I can understand since it's setting up Pipeline and filters but why doesn't it allow HTTP level access Is this a bug Does anyone have a workaround to this N.S. ...Show All

• .NET Development Which class I should use in communication?

  Hello, I am a new user of this forum. I need some advice. In System.Net.Sockets namespace there are two class, NetworkStream and Socket Classes and in System.IO there is Stream class for using TCP/IP connection between server and clients. I have read their members, properties and events in MSDN, they are nearly the same but I wonder there are any advantages or disadvantages between them. For my program which class should I use I use TCP/IP and DNP (Distributed Network Protocol) for my application, some devices connected to LAN sends data to my application also my application can send commands to these devices. But I can not decide which class do I use. I have not been using my english in writing for a long time, therefore sometimes ...Show All

• Commerce Server Adventure Works Catalog Import Export

  Hi All, I am a beginner in CS 2007. I wanted to start changing few things in the CS 2007 Starter Site. I wanted to know that if I remove the Adventure Work's Catalog then can I actually import it back I have seen a facility in the menu of import, so I presume that would do it. But would the Adventure Work's Catalog be restored exactly as it was configured when I configured the Starter Site or do I need to do some other configuration once I have imported it back. Also does any one know a way of hiding a catalog or specific products in a catalog could be hidden Many thanks, Shriroop. The starter site contains the AdvworksCatalog.Xml file which contains the Adventure works catalog. You cn import ...Show All

• Visual Studio Tools for Office Adding Series to graph throws exception

• Game Technologies: DirectX, XNA, XACT, etc. JIT register allocation and bounds checking

  A few questions for Shawn or one of his buddies: 1/ Does the register allocator used in the XBox JITter use all of the available scalar floating point registers If not, how many can it deal with 2/ Does the XBox VM ever skip array bounds checking, and if so under what conditions 3/ Presumably there are no bounds checks when using unsafe code and pointers 4/ Are the method inlining limitations of the CF VM mentioned here still applicable to the XBox VM - especially the one about not inlining any method with floating point arguments or return values (yikes, that would be all floating point setters and getters!) Andy. 3/ Unsafe code is fine on the XBox. Really Have you tried it If ...Show All

• Visual C# Trying to understand IComparable

  I try to understand an IComparable code example. MyIndividual object uses the IComparable interface with the CompareTo memberfunction. MyGroup object contains a private ArrayList with several MyIndividual objects. When executing the MyIndividual.Sort function the ComparTo memberfunction is called by the operating system many times to do the comparison. So far so good. The CompareTo memberfunction compares some property of the received argument object against the same property of the 'this' object. Now I don't understand how the 'this' reference is pointing to one of the MyIndividual objects. Which or What is responsible for initializing the 'this' reference I am confused as normally I think when memberfunction code ...Show All
