  Hi, I would like to convert my adjancey set model to a nested set model with a left and right. I understood this part. Root Node is always with a a Left = 1, right = 2*(Select Count(*) from Table) How do the leaf node get the left and right numbers.

• Game Technologies: DirectX, XNA, XACT, etc. XNA multiple bounding spheres

  i have been making a pool game and now i need to add more balls, i need to put more balls onto the table first then what would be the collision code for all the balls if they were in an array Whether the balls are in an array or not does not matter. The concept here is that you check each ball against the other balls using a simple bounding-sphere collision formula. There are many articles on the web that explain bounding-sphere collisions. Since it's a pool game, that's the least of your worries. You also have to factor in drag, spin, speed/direction vectors etc....but I guess this is a start.

  So when XNA Studio Express comes out I and many other budding(a.k.a. newb) programmers will flock to our PCs to make our own games, but my question is what is the best type, or genre to begin with Would it be a good idea to start 2D, or would jumping into 3D be an option I want to start off with somthing that I can ease into and not get overwhelmed by anything too hard. Thanks for any help you more experienced programmers can give me. (but only on windows if we're talking networking ) Dammit, Jim, i don't want to fight you.

• Windows Forms ToolStripManager LoadSettings Problem

  I have an application which contains many ToolStrips inside a ToolStripContainer. I am trying to use ToolStripManager to load and save the settings, so I've set up a FormLoad and FormClosing event to call ToolStripManager.LoadSettings(this) and ToolStripManager.SaveSettings(this) respectively. I can see the file is being written, with the correct values, but when LoadSettings is called, the values are ignored, and the toolbars reset to the values not in the user.config file. Is there something that could cause this that I am overlooking Thank you Andrej, I have seen the thread you suggest me.

• Visual Studio About the Compability between .Net and COM object

  I am currently working on inhouse libraries upgrade from .Net 1.0 to 2.0. In the .Net 1.0 libraries we have used COM object Craxdrt.dll and functions like craxdrt.AddPictureObject, craxdrt.AddTextObject. I would like to ask if there are any alternatives in .Net version, or I still have to use the COM object for compability. Using craxdrt.dll (Report designer component, RDC) is not even supported in the .Net 1.0 libraries let alone the 2.0. It is only supported through COM languages, and is being deprecated. The new way to do it is through the RAS SDK which requires Business Objects Enterprise or Crystal Reports Server, and if you are using Visual Studio 2005 you need the XI release 2 version of these pr ...Show All

• Windows Forms serialize TreeNode-derived classes

  Hi, I want to serialize my custom class derived from TreeNode. After searching on Internet I found many answers that confused me so I'm going to as many questions hoping to get the right answers from you. 1) TreeNode is inheriting from MarshalByRefObject so it's not possible to serialize it. but I can do it like this so what are they talking about Code : TreeNode treenode = new TreeNode(); treenode.Nodes.Add("1"); treenode.Nodes.Add("2"); treenode.Nodes.Add("3"); treenode.Nodes.Add("4"); System.IO.FileStream file = new System.IO.FileStream(@"c:\test.dat", System.IO.FileMode.Create); BinaryFormatter serializer =new BinaryFormatter(); serializer.Serialize(file, treenode); ...Show All
