• Game Technologies: DirectX, XNA, XACT, etc. Multiuser games?

  Just curious... but has anyone used XNA/C# to develop MOG's or even MMOG's Nick, IThe 'middle man' you mention doesn't have to take something away from performance. In the case of Java, it allows highly optimistic compilation to take place, which can be dynamically recompiled to work in a less optimistic manner when the highly optimistic case would break the program. This simply isn't possible in C++. For instance, a program might provide several integration methods for rigid body simulation - Euler, Runge-Kutta etc. Now ordinarily you would access these via a function pointer in C, or via polymorphic classes in C++. In either case, the code will never be inlined, as we don't know which the user will choose at runtime. The JVM ...Show All

• .NET Development BeginConnect/EndConnect + BeginReceive Exception

  Hi There! I'm getting this strange behaviour when using async sockets with c# .Net 3.0 The problem goes like this: I start to connect to a tcp server with BeginConnect(), once the ConnectCallback is called, I finish the connection with EndConnect(). This then fires an event "OnConnected". A handler for OnConnected, receives the socket that I just performed EndConnect() on, and immediately starts BeginReceive() on it. Now the problem is that BeginReceive() throws me an exception: "A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a send call) no address was supplied" But, EndConnect() finished without any exceptions So eh, what is the problem ...Show All

• Visual FoxPro Grid Reusable Form or Active-X question. Any Help?

  Hi, A problem I am always facing when I am creating a new software is the following: I usually need in every software a grid to display my records in some sort of way from a table of cursor. Ok the grid will change a bit from form to form and from software to software (different row colors, sometimes I ll need to sort by columns somentimes not, different fonts, buttons in grid or not or others things etc etc). Is there anywhere around the Internet such a ready made form-grid or Active X control that will do my job instead of each time spend a day of recreating it from almost scratch If it is also free (or cheap!) it would be really really very very nice :) Any help Thanks, Athan PS. Also any other forms - or links that ...Show All

• Audio and Video Development Regarding Applicative Style

  We can view a tick like this : tick start Live DOM a) evaluate all Xpath Expressions on LiveDOM (since all Xpath Expressions are evaluated on LiveDOM at start of the tick). b) Apply Animation ( LiveDOM modified) c) Draw LiveDOM tick end The question is when is the applicative style ( which is applied at every tick ) applied before a) or before b) Thanks for your reply. I think that basically means somewhere after a) i.e. after evaluating all the XPath Expressions. i.e. LiveDOM used for evaluating the XPath Expressions does not have(current tick's )applicative style applied to it. ...Show All

• Visual C# Another word about Enumerations

  Hello All. I wonder if I could get you folks to check my thinking on this, because I'm wondering if there isn't some aspect of enums that I'm overlooking. Now, as I understand it, an enum consists of an ordered set of named integer constants with the ability to reference the name of the constant as a string. So, the salient points are these: named: good for code readability constant: good for switch statements integer: good for control statements and indices; bad for type consistency string: good for basic output; n/a for localized output Okay, the app I'm designing has several collections and matrices representing various states and lookups, so I really need named integers for indexing in order to keep the cod ...Show All

• Windows Forms Controlling one form to another

  Hi, Is there any way to control parent form from child without using showdialog(). I am not using MDI form. suppose I opened Form2 from Form1. Now I want to change some property of Form1 from Form2 then how is it possible Sven De Bont wrote: There's no need to create a new property for this, since the form class allready provides one. You are right, but Form.Owner needs a (Form1) cast to access custom members added to Form1. If there is no need to change those custom members, using Form.Owner is much better than what I suggested. I actually don't know which method is better to access custom members, adding a CallerForm property of type Form1, or use Owner property and cast it to Form1 when it's need ...Show All

• Microsoft ISV Community Center Forums Deleting tabs when a cell is emptied

  Hello everyone, I have an excel macro where, whenever i put a name into a cell in the range B43 to B77 on the very first worksheet, a new worksheet is created that has the name of whatever is put into the cell. what i would like to be able to do is to create a macro that would, whenever one of the cells is cleared, to delete that specific worksheet that was created when the name was entered. any help is appreciated :D Nick This should be fairly easy to do. Since you've already got code that creates a sheet when a value is added within that range, I'd recommend creating a Collection which contains Items equal to the name of the sheet (the value of the cell) with Keys equal to Range.Address of th ...Show All

• SharePoint Products and Technologies Users added via a domain local group don't get access?

  I have a user who isn't added directly to the site but is a member of a domain local group that has been added to the viewers group. The user gets access denied. If I add them to a domain global group in AD and add that domain global group then there is no problem. Is there a problem giving access to domain local groups (these are not the same as machine local groups) as opposed to domain global groups Thanks, Mark I discovered this was because my domain was working in mixed mode and domain local groups are scoped to the domain controller only in that mode. Switching to native mode solves the problem. ...Show All

• Visual Studio 2008 (Pre-release) Black Window on WPF RTM

  I just came back from TechEd Europe and installed Fx 3.0 on my production machine where I never installed any beta release before. As I open a WPF application, the screen become black. The only way to stop this is to shut down the WPF application (XAMLpad or VS.NET or other) via RDP on another PC (killing the process). Furthermore if I open a terminal service window on the same local machine, I see the window flashing and the ystem become unstable.

• .NET Development problem with CLR dll, but only in debuger

  I am making a CLR dll in C++, and testing its consumption in C#. For the sake of this thread, the CLR dll will be called ' MyCLRdll ' and the test propgram will be called ' MyTest ' I know the problem relates to the progress bar parts of the dll and test and cross threading What I don't know is why this problem ONLY happens in the C# debugger, or how to fix it. When I go into the Debug folder and double click MyTest.exe every thing works perfectly; its just when I hit the play button in VCS Express that the problems happen. The thing is MyCLRdll pretty much has to work in the IDE too because it is a devolpment tool Hi, There is the problem, the timer uses a thread from the threadpool, ...Show All
