• Game Technologies: DirectX, XNA, XACT, etc. Where is my fragment linker?

  Unless I missed it (I looked as hard as I could) it doesn't look like the D3DX fragment linker (which also had a MDX version, mind you) made it into XNA. This confuses me greatly because anything serious with HLSL and any shader model requires support for run-time linking of shader fragments for performance. The only other options are: 1) Flow control instructions, which come with a very large instruction count and performance hit, especially in pixel shaders, and they aren't available in shader models 1.1 or 2.0. It makes very little sense to waste dozens of instructions on every pixel for something that stays exactly the same for all pixels in the same batch. And no, not even static flow control is available in PS2.0. 2) Co ...Show All

• .NET Development FtpWebRequest dies when trying to connect to vsftpd.

  I've got an application I inherited, and it was supposed to use secure ftp to get information to an ftp server. Turns out it didn't have this option set, and when I tried to get it to connect via sftp, it failed. I've run into that problem before with http requests, so found the appropriate piece of code to accept certificates (inherited from ICertificatePolicy), and set the ServicePointManager to use my new class. Well that works, but falls over when getting the response from the ftp server (vsftpd running on linux I think). The response is; 234 Proceed with negotiation. Is there some way that I can get the FtpWebRequest class to recognise this as a valid response Thanks in advance I tri ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Threaded code shows no speedup on XBox 360: More to it than Threading namespace?

  I wrote some Mandelbrot code that I can divvy up into multiple threads. On my multiprocessor dev box, I get the expected speedups. Identical code on the XBox 360 shows no difference in calculation speed. Does the XNA Framework actually distribute the processing, or is it serially multitasking on a single core I'm actually seeing something very similar. I'm procedurally generating a world using a couple of static classes, each of which has a bunch of static methods containing their own fields and so on. If I call these routines from the main thread (for all 400-odd objects I'm generating) it takes about 22secs. If I split this over 2 threads, each doing half the work, one will take slightly less tha ...Show All

• .NET Development How to serialize back a ConfigurationElement object?

  Hello In the System.Configuration namespace you have several classes (like ConfigurationElement) which help you to deserialize custom configuration sections into objects. Now I have an object from a class which derives from ConfigurationElement and I'd like to serialize it back into its original xml state because I'd like to write it to a trace output (XmlWriterTraceListener). I tried to use the XmlSerializer to serialize the object but this did not work. I got the following error: You must implement a default accessor on "MyProperty" because it inherits from ICollection. Any other ideas how to achieve this The framework already has a builtin mechanism to deserialize the custom config section. Maybe it's somehow possi ...Show All

• Visual Studio Team System Output of base.Problems collection

  I have a custom rule that loops through all the methods available and checks for a particular violation. If there is a violation, I use the below sequence to add it to the Problems collection Resolution resElement = base.GetResolution( "error string" ); Problem prbDescription = new Problem( resElement, "Class Name" ); base.Problems.Add( prbDescription ); I have the above set inside the loop and during the execution (debugging), I am able to see the base.Problems having the list of items that were detected for violation. During debugging, I am able to see the list growing as I add the violations to base.Problems At the end of the Check method that I have overridden, base.Problems is returned. But in the ou ...Show All

• SQL Server Searching encrypted data; using MAC secret data

  I just finished reading an article on how to search encrypted data efficiently and they suggested creating a new column with a Message Auhtentication Code. To be honest, reading the aritcle makes my head hurt. I can hardly understand what they were doing myself and I can't begin to explain it to a developer. Are there any easier ways to search encrypted columns for a speciifc match If not, does any have some stored procs that implement this messy MAC stuff TIA, Barkingdog If the article Sung pointed out is the one you have questions about I am the author of it, and I will be more than glad to help answering any questions and help you get a solution for your particular scenario. ...Show All
