• Game Technologies: DirectX, XNA, XACT, etc. End users shouldn't have to rewrite XNA math functions in order to improve performance.

  The overhead of passing a 64 byte Matrix by value is significant. Most especially when you are comparing two matrices for equivalency (==), or performing a Vector*Matrix multiplication (Vector3.Transform(Matrix)). The following matrix comparison function performs 5-10 times better than your built in == comparison. If the matrices are equal, then it is about 5 times faster. If they are unequal then it fails fast, and is about 10 times faster. public static bool Equals(ref Matrix a, ref Matrix b) { // i check the diagonal first for quick fails return a.M11 == b.M11 && a.M22 == b.M22 && a.M33 == b.M33 && a.M44 == b.M44 && a.M12 == b.M12 && a.M13 == b.M13 && a.M1 ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Partially map a resource

  I saw in the DX10 documentation that the function D3D10Buffer::Map() doesn't seems to allow the user to modify only a subpart of the buffer. So if I havefor example a very large vertex buffer and I need to modify just one vertex, do I need to resend the entire model to the GPU Thanks in advance. Partial lock of resource in D3D9 actually was not widely used feature. To update only part of resource you just Map() it and write only bytes you need - you don't have to overwrite content of whole buffer. Most efficient way to do this for VertexBuffer - is to use D3D10_MAP_WRITE_NO_OVERWRITE flag while Map() it. Look in DX10 documentation how to correctly use this flag. ...Show All

• Visual Basic Using FORTRAN in Visual Basic 2k5

  I'm kind of new to programming, so if anyone can help me out I'd appreciate it. I'm writing a program that has the majority of its computational work written in FORTRAN. The FORTRAN program takes a file input which I have create successfully, but I don't know how to declare and call the FORTRAN library from VB. Can anyone help me out JE First, is your Fortran DLL managed or not   I'll bet my whole paycheck 95% of the time it's unmanaged.  And if it is managed, it's going to be slower than molasses in my grandma's deep freezer. Make sure you compiled your Fortran DLL as a DLL: Your fortran compiler produces a DLL file and this goes in the same directory like your VB executable.  ...Show All

• Audio and Video Development Animation not holding.

  I implemented a menu tray that raises and lowers. It worked in the first version of the iHDSim, but in the new version the menu tray raises and then disappears. Then the lower tray button key assignment will make the tray appear again and then lower.

• Visual Basic Not able to debug my vb.net program

  Although in the Configuration Manager I have selected "Debug", yet my program does not stop at breakpoint. Can someone help me please Thanks. I am using the run button in the menu bar. Well, in fact if I give the breakpoint in my main module the tracing is activated only for that module. When the control is transferred to sub modules, the tracing is no longer there. From then on, the program simply gets executed without allowing me to trace. ...Show All

• SQL Server Using Server.Transfer to Post report parameters

  Can I use Server.Transfer in an ASP.Net web page to transfer the variables via POST rather than the less secure GET in the URL. I have tried creating a page with form elements with IDs that are the same as the report parameters and using Server.Transfer to send that information to another ASP.Net webpage that has the reporting services control on it linked to the report. You can add the IUSR to the report server permissions with view reports priviledges. You can do this in Report Manager in the Security section. Go to Home\Properties\Security at http://localhost/reports . Have you tried Response.Redirect instead of Server.Transfer I have not tried either the way you are attempting, but my understanding ...Show All

  Hi, Attempting to open a new database engine from a Windows 2003 R2 server (x64) which is running SQL Server 2005 to my desktop PC (XP Pro) which is running SQL 2005 developer edition. I’ve opened up TCP/IP and named pipes and enabled all protocols within surface area configuration and server configuration manager but get this… An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

• Commerce Server Root Category Ranking Issue

  Hello, I'm having an issue with the .GetRootCategory method call. Here's the situation. Before I call the .GetRootCategory I set a where clause and pass it along. The method doesn't return me any results. But when I don't include the where clause I get expected results. Here's what I did (The where clause is included): 1. The current catalog has ranks for all root categories. So I created a new category with no rank and boom that new category was returned. If I set a rank to that category; it is not returned anymore. I've traced the issue in the ctlg_FillCategoryDescendants sproc: Here's the code. IF @oid = -1 BEGIN if (@fVirtualCatalog <> 0) BEGIN -- Insert the Categorys first-level descendents in the #Desc_Oids ...Show All

• .NET Development Web Service client has "nothing" for result.

  I have a crazy situation where I'm hitting a web service (written in Java), with a client I'm writing in VB (2005, with ASP 2.0)... the return type from the web method is a complex data type (not that complex - just has four different strings). It is consistently returning "nothing" when I call the web method. Here's the thing: I can hit the same web service with XML Spy sending in the same information, and that works just fine. I also used a sniffer tool and was able to see that my client is indeed receiving the correct response back from the server via HTTP... it's just that Dot Net is losing it somehow and by the time it gets back to my VB code, it says there's "nothing" there. (Argh!) Has anybody hit a situati ...Show All

• Visual Studio 2008 (Pre-release) how to bind to a dictionary (or something like that)

  I've got a dictionary<String,Object> and want to bind a xaml object to the key of the dictionary so it shows the corresponding value. So far I only found ways to bind to get/set accessors, or to attached DependencyProperties, but can't find a way to bind to the key of a dictionary. Is there any way to bind to something like this thanks, Sam I'm not sure, maybe I asked my question wrong. I'm not trying to create a tree, I just need a play binding to a key value I don't know at compile time. I don't know if my key is Name, Number or HumpyDumpy. And I don't know how many keys I got to bind to, it might be 2, it might be 200. I get this information at runtime. So I can't add a property ...Show All
