• Game Technologies: DirectX, XNA, XACT, etc. Question about 'EffectParameter' class

  Given that the EffectParameter class is sealed I need to ask: any chance for future versions to take advantage of generics for methods like SetValue and GetValue I 'm not meaning to create a new 'EffectParameter<T>' class (what'd make it difficult for the 'EffectParameterCollection' class), but something like: GetValue<T>() or GetValue<T>(T dummy) -the latter to avoid the use of the static <T> when calling the method, instead of GetValueVector3() and so on (ditto for the methods that return an array). SetValue<T>(T value) , instead of overloading SetValue(...). That way it could be easier -for us- to implement a sort of "fx parameter mapping" technique as well as an 'EffectParameterHan ...Show All

• Smart Device Development Compacting data on compact framework 1.0

  Hello, I have an smart device application which has being developed on vs 2003, using compact framework 1. Now what do I need is to pass dataset object, or if that wouldn't be a great solution - an string obtained from ds.getxml() from and to an smartdevice from and to an webservice. So far, I've searched some code sample in order to compress one of this two ways but I wasn't able to find it . Thank you for the support If you need a way to improve the performance of a dataset transfering between the mobile app and web service, consider the following: Design your application so that only the needed data is transferred. For example transfer only changed data. In case you are targeting CF2.0 you may use DataSe ...Show All

• .NET Development Reading file size and then store the name, date and size in database,

  I'm trying to make a program that basically say that every morning run this directory and scan through all the files. Then record the name, size and the date and then compare with the one that already existed in the database. If everything is match then pop up message say GOOD. If something has been changed then pop up a message say NOT GOOD. But aslo if i know that there was an update on the file so the date has been changed, that program should also have an update function to update the database. For instance File1 800kb 7/18/2006 File 2 1mb 7/17/2006 because this is the first time i run this program so i have to insert this into the data base. so after inserting, the database will have a list of file 2 and 1 with ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 3D Shape Order, Artifacts (screenshots)

  More progress, more problems. Perhaps this is from being used to OpenGL, but I'm having problems having 3D shapes appearing correctly in front of or behind each other. It appears that they are displayed by the order rendered in the Draw() call, and not by position. Is there a simple setting to enable/disable here In these screenshots, the sphere (TriangleStrip) is drawn first, and the cube second (TriangleList). The cube is inside the sphere, but the cube appears to be in front of the sphere when displayed. Like so: http://www.cybra.net/gd/images/SphereCubeProblem.jpg Rotated 180: http://www.cybra.net/gd/images/SphereCubeProblem2.jpg The lighting is off, but that's a whole separate thing since there's zero mention of lighting ...Show All

• Software Development for Windows Vista IGraphBuilder vs FilgraphManager

  I am trying to get a HD mpeg file to play in DirectShow using C++. I have two different applications one in C# and one in C++. The C# application renders the HD mpeg file just fine and the C++ programs gives me the following error "An invalid media type was specified.".

• Windows Forms Pushing data into winforms clients.

  Anyone have any advice on pushing data into winforms clients I need winforms clients to listen for changes made to a sql server 2000 database and automatically update itself. Is this possible Perhaps using .net remoting I was thinking about how to do this, and my line of thinking is this: I would write a c# service which would have a list of all connected clients and methods which would be called to update the database. So the client applications wouldn't call sql server directly, It would call methods on the service letting the service know it wants to update something on the database and if successful, notify all connected clients. Does that sound correct How do the big boys make apps like instant messengers, games, etc. ...Show All
