• Architecture Looking for guidance

  Hi, I am developing a ASP.net 2.0 web app in C#.I am going to use MVP pattern.I am designing,my domain model first.I have 2 questions.. 1. I want to use 2- way databinding,with gridview,for which I can use objectdatasource..should i create an objectdatasource object representing my domain,since my classes in domain wont follow pattern required by objectdatasdource.. 2...In MVP pattern,how to trransfer data from presenter to model..use a dto,or directly model classes.. thks I think you mean MVC. In fact, if you are using code-behind model, you are using a variation of MVC (Model-View-Controller) pattern. If you put your data access coding into another class, your can further decouple model with controller. For mor ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rendering to multiple full screens

  For a special application we need to do the following using a NVidia Quadro FX 4500 X2 (2 GPUs with 4 outputs) on a system with 4 CPUs. - we get 8 input images from acquisition devices - these 8 images must be rendered to 8 textures using fragment shader programs in two render passes - the resulting images must be rendered to 4 render contexts fullscreen in full HD Resolution (1920x1080) again using a fragment shader program All this should happen as parallel as possible with 25 fps. We do not need any user input or any animation. We have not yet decided, how to do the implementation. As we see it, our possibilities are: - using DirectX 9.0 with unmanaged C++ - using DirectX 9.0 with managed C++ or C# - using OpenGL with unmanaged C++ - us ...Show All

  Does anyone know how I can show that balloon that windows shows when you are trying to logon and your caps lock key is on There are some VB examples out there of how to show balloons, but I need to show one using C# not VB as a warning to users when their caps lock key is on and they are trying to logon to an internal system.

• SQL Server Alternative to Merge Replication?

  Is there a simpler alternative to merge replication I am concerned about the splash of GUID across the DB, performance issues, and the complexity of the deployment. there are many articles and whitepapers about replication deployments on the net, maybe we can ease you if you describe your scenario and deployment concerns. i.e. how many subscribers are we talking about as far as GUIDs, if you specify correctly column lists for all your insert statements, you shouldn't have any application breaks, it should be seamless. ...Show All

• .NET Development What's wrong with this XML construction

  I'm trying to upload data from a PDA data store to a remote server, and am writing an XML document to transmit the data. The data is stored in two tables, a transaction summary for each transaction, product level details for that purchase. I transmit multiple transactions at a time. The XML I'm creating for each transaction looks OK, but when I try to append this node to the document, it fails with an 'Invalid ChildType' error. I create my XML by first creating the document ( xdoc ) doing the minimum initialization, then making repeated calls to xdoc.CreateNode(.. ). It has always bothered me that I create a node at the document level but then add it to a child node, but I've never had problems with it. Any help is greatly appreci ...Show All
