• Game Technologies: DirectX, XNA, XACT, etc. Point Sprites on XBOX 360 causes crash

  I have an application that draws a large number of point sprites on the screen using DrawUserPrimatives using additive blending. This works fine on the windows version, with around 4 million point sprites being rendered. On the XBOX, when there are greater than around 20,000 sprites nothing draws and then the program exits with code 0 and no error messages. Any insight into what I'm doing wrong -Adam Here is the relevant shader code: texture Texture; float4x4 WorldViewProjection; float alpha; sampler TextureSampler = sampler_state { Texture = <Texture>; MipFilter = LINEAR; MinFilter = LINEAR; MagFilter = LINEAR; }; struct VS_OUTPUT { float4 Position : POSITION; float4 Color : COLOR0; float2 TextureUV : TEXCOORD0; f ...Show All

• Visual Studio 2008 (Pre-release) how to inherit winfx usercontrol?

  In the project I attached, I have two winfx usercontrols named UserControl1( parent class ) and UserControl2( child class ) .I want UserControl2 inherit UserControl1. Also in UserControl2 I overwrite the parent method. After inherit from the parent class UserControl1, I want to append a new button in UserControl2.xaml, but it seems that UserControl2.xaml can not display the new button control, just display the parent usercontrol1.i find a workaround is to invoke the base class method to add the new button control in UserControl1. xaml.cs. Could you please tell me why I can not add the new button control in UserControl2.xaml directly =========== UserControl1.xaml <UserControl x:Class=&quo ...Show All

• Visual C# Internet Control..

  Hi. I'm an engineering student and i'm working on my project titled 'Internet Access Control' for our college. Our college has a server connected to our network lab where internet is accessed. I'm using sockets programming and i would be glad if you tell me which classes i have to use along with the addressing considerations. The aim is to have the user (student) log in and the user can have access to internet only for a fixed amount of time. The server should maintain login information and keep a watch on the time for which the user has accessed the net. I mainly need to know about how the program can know that Internet service has been started and ended, how should it do it What are the packages involved Thanks.. Pro ...Show All

• SQL Server SQL Backup hangs, server freezes

  We have SQL 2000 running on Server 2003. The server has 4 GB RAM, RAID 1 and has the /3GB switch in Boot.ini. We have 6 databases, the largest is about 14 GB. Until recently I could use Enterprise Manager to perform database backups to a folder on the same server but now the operation fails. After selecting the location for the backup and clicking OK, the hard drive light comes on but goes out after 15 - 30 seconds. The progress bar does not move. I've waited and waited but nothing further happens and the server doesn't respond. The only solution is to push the power button and let the server re-boot. Very occasionally the backup will run for a minute or two and the progress bar might get to about one third of the way across, (in which cas ...Show All

• SQL Server Dynamic Text Parser?

  Hi Guys, I have a script task that is supposed to read and parse a fixed width source file. Basically, I want to make the FieldWidths dynamic so that I'll be able to reuse this package with different files. So Instead of hardcoding the field widths directly into my script task, I want it to be stored somewhere that the package can get when executions starts. Is there a way of doing this The code looks like this: Using Reader As New TextFieldParser(mTempFilePAth) Reader.TextFieldType = FieldType.FixedWidth Reader.SetFieldWidths(1, 8, 8, 8, 4, 8) <-- I want to change this to handle dynamic widths. Hi, The best way to make your package re-usable is to use a & ...Show All

• .NET Development Not the same Primary Key in DataTable and in SQL Table

  The database: I have three tables in a Microsoft SQL Server 2005. Those tables are given and can not be changed. The main table of those three is called spbTable and has a primary key (int) called spbId. Further settings of this primary key are: (Is Identity) = Yes Identity seed = 1 Identity increment = 1 The other two tables are dependent on the spbTable with the foreign key spbId. The code: I am coding a web application using C# (ASP.NET 2.0 and ADO.NET 2.0). I was generating three DataTable using the Designer of VisualStudio 2005. So I have three TableAdapter, one for each DataTable and each DataTable has its own sql commands. The code I wrote looks like the following: ...Show All

  Problem: to execute linq query on Iqueryable object that is non local (remote object) Solution: generic IQueryable local proxy that will call some remote proxy, and this remote proxy will locally IQuery remote object why not just remote this Iqueryable remote object – because Expression is not serializable in fact Expression can have local code calls so in some situations it may be hard to serialize it. BUT some subset of all-possible-Expressions-set IS serializable.

• Visual Studio Team System Error 28925 TFServerStatusValidator

  Hi all. I have to install the TFS for our programmers department but I'm unable to get it working... The server is W2k3 sp1, it's a single server install.

I'm quite desperate now, has anyone another idea Where can I start troubleshooting Regards Have you checked out this post on the forum http://forums.microso ...Show All

• Visual Studio 2008 (Pre-release) Transformations on AdornedElement are also applied to Adorner?!

  Hi, I’m using Adorners on shapes and other controls. I’ve noticed that the Adorner is scaled, when the AdornedElement contains a transformation with a scale transform. But I don't want the Thumbs and the bounding rectangle in the Adorner to be scaled also. Is there an easy way around this, or do I manually have to scale these back again. In ArrangeOverride I might be able to scale down the Thumb accordingly if I find that there is a scale transform applied to the AdornedElement. It might not be that easy with the pen used to draw the bounding rectangle though, since it's no likely that it should be scaled down equally on all sides. Thanks in advance! / Joel You'll need to override Adorner.GetDesiredTransf ...Show All

• SQL Server Upload subscription report into other database

  I have a subscription set up that delivers reports to email addresses. What I'd like to accomplish is not to have emailed the reports, but insert the report into a document management system that uses a MS SQL database. Basically I would like to be able to execute SQL statements when the reports are being delivered. I have found that when a subscription is set up, a background job is created that calls the stored procedure AddEvent. This stored procedure inserts a line in the table Event (in the ReportServer db). Now when the email is delivered, this inserted line is deleted again. What I'd like to know is if there are possibilities to change this procedure to add some code where I can insert a rendered report in another database. ...Show All
