• .NET Development Derived types and System.Collection.Generic.Dictionary?

  Hi, I have a Dictionary in one of my classes: private Dictionary<string, RobotPart> _parts = new Dictionary<string, RobotPart>(); RobotPart has many derived Classes (Rod, Joint, Body, etc.) . I have a method called GetFlatPartList that flattens out a treelike structure of RobotPart objects, for easy iteration through the child objects. Hopefully, once I hit "post" my tabs will be kept for the following method: EDIT: I took this method out, and placed it in the following post for readability Now, my problem is that my program will crash, giving me an invalid cast exception when I am trying to search (using a for each statement) for any Type other that RobotPart, even though they (Joint, Rod, Body, etc.) are ...Show All

• Visual C# Help required to solve circular dependency problem in vb2005

  I am working on an application design that requires two projects to cross reference each other. I found the excellent Formfactory / Interface example/solution (listed below) on this forum. Unfortunately I am not C# literate. I understand and appreciate the method, but my attempt to convert it into vb2005.net has been defeated by the C# syntax. I would greatly appreciate someone (multilingual) providing a translation into vb2005.net Here is the C# solution: The pattern to solve this is abstract class factory , together with the singleton pattern. What you have to do is the make a classfactory for the forms . This classfactory you can place in your main program, which anyway MUST reference your assemblies, thus it w ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How do I load a 3d mesh (.x file)?

  How do I load a .x mesh into my scene The space game seems to use its own format (which it names .swm), and there's nothing in the help. I've been scanning through through the classes in the Framework namespace, but I can't see anything obvious! Is .x the recommended format for objects like this (If not, I change my question to be about the recommended format :D) If anyone knows anywhere that has some nice .x meshes I can play with, that'd be cool too. The only one I have lying around is a chair, and that's going to look a bit funny running around my game :D The Content Manager is part of the framework so it exsists in the Beta. However all the stuff you need to get you data in the Model format is n ...Show All

• Smart Device Development when a socket listen on ppc 2003 what is the correspondant port on pc?

  I have one ppc 2003 connected through an USB cable to a pc (activesync 4.2) but i can't find any way of connecting (sockets) from a pc app to a ppc one that is listening... Is there a port translation between them example: TcpListener mylistener = null ; try { mylistener = new TcpListener ( IPAddress .Any, 2072); } catch {} mylistener.Start(); TcpClient myclient = new TcpClient (); while (!mylistener.Pending()) { Thread .Sleep(500); } myclient = mylistener.AcceptTcpClient(); On pc i think ppc Ip is 127.0.0.1 (local loop) but what about the 2072 port TcpListener mylistener = null ; try { mylistener = new TcpListener ( IPAddress .Any, 2072); } catch { } mylistener.Sta ...Show All

• Visual Studio Tools for Office Databinding CheckedListBox .Net 2005

  By luck I'd already stumbled across the datasource as I had replaced a normal listbox of the same name and the code continued to work. I have a further requirement - I am binding to a generic collection of objects, for the sake of argument lets call them "Person" objects. Say each Person object has a property of "Married" which is a boolean value. What I'd like to do is bind the checkedlistbox to the Person collection and then bind the Checked property of each item to the married property. That way all of the married people are checked. Seems to make sense to me - Is that possible, or do I have to work around it in code Hi John It's always dangerous to post a follow-up on an old ...Show All

• Visual C++ Symbols different on x64 vs x86

  I have a 32-bit app that I am trying to port to 64-bit. I've noticed that for exported C style functions that the leading _ gets dropped by the 64-bit compiler. For example, from dumpbin /symbols: From 32-bit object file: 00D 00000014 SECT3  notype       Static       | _GetEnvFunc From 64-bit object file: 00C 00000028 SECT3  notype       Static       | GetEnvFunc All of the compiler flags are the same, except that -DWIN32 and -D_X86_ have been replaced with -D_WIN64. For the linker /machine:x86 has been replaced with /machine:x64 and all other flags are the same. The problem is that the above ...Show All

• Visual Studio 2008 (Pre-release) How come this FaultException gets bi-passed by the Global.aspx On_Error handler?

  Before WCF, I remember this behavior when using the WSE extensions to call webservices and getting unexpected results that caused the soapformatter to choak before passing control to the asp.net page. But can someone fill me in on why we get this behavior when using the WCF libraries I have a ASP.NET web page instantiating the WCF proxy and calling a WCF service over httpbasic bindings. For some reason, this generic fault exception did not get caught by the global.aspx error handler. Thanks! -B. Server Error in '/' Application. There are a few things happening here. When you throw a FaultException, or an Exception of any type at the service, it is wrapped in a FaultException in order to serialize the SOAP fault. At the web p ...Show All
