• Game Technologies: DirectX, XNA, XACT, etc. Game.GameServices article

  I put up an article about Game.GameServices and the IGraphicsDeviceService. http://blogs.msdn.com/mitchw/archive/2006/09/06/742955.aspx Good article but the question has become how do we go about creating GameServices, creating those singletons. I have a few ideas wich would exploit the "service" model very well, but have yet to figure out how. Edit, Do we simply add an interface to provide the service and add code in the component's constructor to add the service Ie like this Game.GameServices.AddService( typeof (I MyService ), this ); ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Can we take advantage of 360 hardware using XNA?

  Are there portions of the XNA framework that get benefit from the VMX instructions available on the Xenon processor The quaternion discussion got me researching it, but I can't find any discussions at that low level. The current answer is that the VM will not generate VMX instructions. It may be that some of the system libraries do, but also, many of the system libraries are themselves written in CLR and thus not that efficient. (This is sadness for things like matrix, quaternion and vector) So, right now, I think the general answer is "VMX is not used a lot when using XNA 1.0 on Xbox". ...Show All

• SQL Server Why IDENTITY field is not set while exporting data through Enterprise Manager in SQL Server?

  I am exporting data to database server from local server through Enterprise Mgr. Data is successfully transferred along with table structures. Only problem remains with the fields which are set IDENTITY. Even I tried to find out ALTER TABLE statement so that I can alter the tables using Query Analyzer but I found that setting IDENTITY through query is not permitted after SQL Server 6.5. Why so Is the any way to set IDENTITY fields without Enterprise Manager Please reply Nishith Shah You have to use 'copy objects and Data between SQL Server databases' option instead of copy tables. This option will keep the identity on the column ...Show All

• Visual C# Recently viewed items

  Hi all I have a question: How can I program (that you can choose it in a listbox)for users, to view their last viewed items (in my cases; videos). I was also wondering how to put a link kind item in the combobox.

• SQL Server time delay when first opening the Sql 2005 Reporting Services

  I noticed that the Reporting Services is taking longer to open in the morning or after a period of time in-active. My guest is that the SSRS is set to idle/stop after certain time when it is in-active state and it will take time to start the Reporting Services when it is activated. My question is how to make SSRS active all the time ie never go to "sleep". What is the Pro and Con of this approach Thanks. I believe the problem is that your application pool is set to shutdown after a certain time limit. Go to IIS, under application pools, right click on the one being used by Reporting Services and go to properties. On the performance tab, uncheck "Shutdown worker processes after being idle ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Bouncing Sprites Demo

  Hi Folks, I have written a program that extends the bouncing sprite demo that is shown in the MSDN - XNA help library. The program by default will randomly position 50 sprites on the screen and move them. When the sprites collide, they will bounce off in another direction. If they hit the edge of window, they will bounce off the wall as well. The code shows the usage of the BoundingBox Interacts function. Firstly is used to randomly position the sprites on the screen without overlapping each other. Secondly its used for the collision detection of the sprites. You can adjust the number of sprites by altering just one constant value in the code. It seems to run smoothly even if you've got 100 sprites on the screen. You can downlo ...Show All

• Visual C# An object reference is required for the nonstatic field, method, or property

  I know you have all seen this one before, for which i am sorry. But I can't figure this out. I am not sure if what I am trying to do here will even work in the end but this is my first project and I am learning as I go, so please try not to laugh. I have a combobox of form1 that is bound to a data source and on form3 I have a report viewer that (I hope) will load using the text that is in the combobox on form1.

• Visual C# Custom Item Property for ComboBox

  Hi, I'm developing a CheckedComboBox inherited from ComboBox and it is nearly finished but the problem is that it's underlying Items property is an ObjectCollection. How can I convert it to a CheckedItemsCollections like the one CheckedListBox has If I convert it to some other kind of custom Collection of my own, how the DataSource property of the base ComboBox of my control affected When the DataSource property is changed, what really goes beneath Too many questions, I know, but all for a nice Control, doesn't worth ;) The property is not virtual and therefore you can't change its definition. You could use the new keyword to hide it but that is not likely to work in most cases and would be a design flaw in my opinion. ...Show All

• .NET Development Help running SQL Transaction in 2005 vb expess
