• Game Technologies: DirectX, XNA, XACT, etc. SpaceWars example, don't understand a scope thing

  Ok, i've been trying to solve this in my own game classes, and I'm wondering how exactly the SpaceWars game does it. for instance, if you look at Font.cs, and go to: public static void Draw( FontStyle fontStyle, int x, int y, string digits, Vector4 color) { float xPosition = x; FontInfo fontInfo = _fontInfo[( int )fontStyle]; for ( int i = 0; i < digits.Length; i++) { //Do't draw anything if its a space character if (digits != ' ' ) { //Look up the character position int character = fontInfo.Characters.IndexOf(digits ); //Draw the correct character at the correct position batch.Draw( SpacewarGame .ContentManager.Load< Texture2D >( SpacewarGame .S ...Show All

• Visual Basic TcpClient.BeginAcceptTcpClient / Socket.BeginAccept / all other variations...

  I've been having a problem with the use of any of the async methods of TcpClient, Socket, etc eating >95% cpu after receiving the first connection. I've been working on this for over a week now and I'm unable to find references to this issue anywhere. I've tried every way I can think of to work around this problem. Even if no data is sent or received on the connection....or if I close the received connection -- some unknown thread uses all the available cpu power after the first connection occurs. I created a small project that reproduces the problem -- I've zipped it up and posted it here: http://www.profitfuel.net/TcpClientProblem.zip If anyone knows how to fix this, please let me know. Thanks, - Joshua Garvin ...Show All

• SQL Server Last GASP on "Insert row in table with Identity field, and get new Identity back " ?

  While I have learned a lot from this thread I am still basically confused about the issues involved. .I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple. To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package. 1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful. 2. ...Show All

• Visual Studio Team System Can't delete folder from the Source Control (get the folder on gray)

  Hi, I get sometimes very weird error when I'm trying to delete some folder from the source control. I get the folder on gray and I can't update the source control window to show me the source control tree without this folder. I tried to do many things to solve this problem - refresh the page, close and open the IDE but nothing really helped, the only thing that really helped me was to sign - in as tfssetup and then to delete again the problematic folder and get entrance again as default user. Just to mention that I am administrator on this machine. Can any one explain why does it happen Thanks in advance, Do you have the "show deleted items" option turned on (Tools -> ...Show All

• Visual Studio 2008 (Pre-release) UserControls in the same project

  I'm using the RTM of WPF but still don't have a clear understanding of how to access usercontrols withing the same project in Xaml. Is there a way to do this or not I've been getting by with instantiating the controls in code behind, but I noticed that the release note whick explicitly states this is a bug is now gone in RTM. What exactly in the syntax for doing this ! ! No. The tools for Visual Studio are still CTP, even though the framework is RTP. We apparently will not be getting another version of "Cider" for VS 2005 either... it will be for the next version. ...Show All

• Visual C# Generic Multi-Dimensional Arrays Comparison

        Hi,     I need to compare multi-dimensional arrays in a function which takes 2 multi-dim arrays which can be any type(int, double, bool...etc). Comparison is done by Object.Equals() of each value in each index of the arrays. As a result, Generic and  Multi-Dimensional is what I need to combine. Any idea I compare 1 Dimensional-arrays with the below code of mine: public static bool AreArraysEqualByVal<T>( IList <T> src, IList <T> dest) { if (src == null || dest == null ) throw new ArgumentNullException ( "source or destination array is null." ); if (src.Count != dest.Count) { Debug .WriteLine( "Array lengths were not equal." ...Show All

• Windows Forms need to include .net 2.0 framework with c# applications?

  is this correct Is the package rougly 20 megabytes I wrote a program using c#, but now need to distrbute it over a very bandwidth limited connection (satellite internet). 20 megabytes is way too much, and I can't be sure that the machines this application is going to have the framework installed. Are there any other options to keep the file size down Ideally I need it to be under 5 megabytes if at all possible (application itself is only about 50k) unfortunately not - redirect them to download the .NET framework otherwise you don't need to include the redistributable pack as the setup and deployment project will automatically download the .NET Framework and install it, if the system does not have the f ...Show All
