Architecture Should a good business tier provide async methods?
Hello Forum I have developed a business tier that in some cases is located remote and sometimes located on a web server with the web frontend. I have frontend developers requesting that I make async versions of all methods or at least of some in the business tier. They want to use this so they can use with the new "Asyncronous Pages" in ASP:NET 2.0. (See links - the last one includes an impressive benchmark) I'm not experienced in providing async methods from a business tier. I have 2 questions. Should a good business tier provide async methods I'm wonding what issues there can be My setup is like this: - The business tier can sometimes be located remote using single call remoting. - The identity must be on ...Show All
Visual Studio 2008 (Pre-release) Getting Error when try to publish the exe with XML file.
Hi, When im trying to publish the exe, im getting 'System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission' error. Actually im reading a XML file inside the code behind. If ill remove that then it wont create any problem i think. Please, can anyone help me to publish it I think you can first publish the xml file on your web server, and use XBAP to read it, actually XmlDataProvider can read the xml data from the remote web server. for example: <XmlDataProvider x:Key="xmlData" Source="http://www.cnblogs.com/sheva/Rss.aspx"/> Sheva ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Can I dispose of instances without explicitly removing all references to them?
As I understand it, because C# is a managed language, I shouldn't need to dispose of any instances I create, as they are removed by the garbage collection when there are no more references to them. I have all my instances of game objects (enemies, projectiles, etc.) stored in lists (System.Collections.Generic.List), so that more objects can be added on the fly, and they can all be updated and drawn with foreach loops. Is it possible to dispose of one of these instances without explicitly removing the instance from the list For example, from within the class itself I suppose this could be done indirectly, by having a boolean property on each object that flags the object for deletion from the list by another loop, but this seems a bit messy. ...Show All

Visual C# VS2005 IDE Crash!
Hi folks! I have an "interesting" problem with the IDE of VS2005 which crashes with no warning or error messages! Below I send info from my PC. The crash happens very often (every 15min) but I have not seen a pattern yet that causes the crash. It happens when I do simple things like clicking at the IDE's menus. I run WinXP SP2 and develop asp.net solutions in C#. I heard that there is a SP for VS2005 but it is still in beta phase and I am a bit reluctunt to install it. I know all of the info below is overwhelming... if you have time please let me know what I can we do to solve this crash. Thanks in advance! George I.

SQL Server Copy Excel sheet to SQL 2005(Dev Edit X64) via SSIS
Ok... This worked on the laptop I had last week. That laptop has ceased to be. I have a new one, which may be my problem.

Game Technologies: DirectX, XNA, XACT, etc. Problem drawing into stencil buffer
I'm trying to draw a alpha-blended texture into the stencil buffer in order to mask a region of the screen. My test stencil texture is pretty simple; it's black with a large white circle in the center (same for the alpha channel). When I render the texture to the color buffer, I see a nice white circle in the center of the screen. However, rendering it to the stencil buffer creates a jagged circular mask region in the center of the screen. It still functions as a mask, but the borders of the circular region are jagged and inconsistant. Here's how I'm setting up the render states, etc.... Any ideas // Setup state to render to stencil buffer only graphics.GraphicsDevice.RenderState.ColorWriteChannels = ColorWriteChannels .N ...Show All

Visual Studio 2008 (Pre-release) January 2007 CTP missing WPF templates?
Perhaps I'm completely incompetent, but I do not find any WPF templates in my recently installed January 2007 CTP of Orcas. Perhaps it's because I installed the latest SDK (so I could have a copy of XamlPad) which is for Visual Studio 2005 I am with you EricSchm, I'm not necessarily ticked off, but I found myself very confused like yourself and having to spend way more time than I had anticipated pieceing all these things together.

Visual Studio Download Errors
I downloaded the trial version and am not sure it worked right. The stated download size was 2.7 GB, but the IMG file I downloaded was only 2.0 GB. I extracted it using ISOBuster, and received some messages that it could not read certain sectors. I clicked ignore and installed the product, but then received an installation error 2324. How do I know if I have it installed correctly The error message is below. I tried downloading again and got the same file size, so I'm guessing 2.0 GB is correct, even though the web site says 2.7 GB. However, I may try again with a download manager.
