• Game Technologies: DirectX, XNA, XACT, etc. Future of DirectX

  I'm starting to get worried about DirectX, because mostly it becomes deprecated, first there was DirectPlay, and now it is the same thing for DirectInput and DirectSound, I've recently read that they are becoming deprecated in favor of XACT and XInput. Could you tell me why is this happening What will become of DirectX in the future Will be there only Direct3D, or will it disappear either I'd like to give you my opinion that deprecating good API's like DirectInput and DirectSound is a bad idea. Take a look at XInput- it allows only xbox controllers, and what about mice, keyboards, or other joypads And mostly I'm concerned about DirectSound, In Vista there is no hardware support for it, does that mean I have to stop working with Direc ...Show All

• Windows Forms tablelayoutpanel flicker / performance

  We are finding that the tablelayoutpanel control is causing a lot of flicker, especially flicker when resizing. We have an windows forms architecture based on user controls and tablelayoutpanels (we use the CAB). Our major flicker issues happen on our detail UI elements, such as a single row data maintenance user control of the pattern: Page Title Label A: TextBoxA Label B: TextBoxB Save Button / Cancel Button These control are organised in a tablelayoutpanel with 2 columns (one for the labels and one for the textboxes) and the desired amount of rows (one for the Page Title, a spacer row, one for row A, one for row B, a spacer row, a row for Save and Cancel buttons). The 1st column is AutoSize and the 2nd column is set to a Size Ty ...Show All

• Visual Studio 2008 (Pre-release) Exception handling

  How can you ensure that no exceptions escape the entry point of an WPF application. In .NET 2.0 this was simple since you could enclose all of your code in the main method with and try/catch blocks. However, in WPF we now have the App.xaml and App.xaml.cs files. I need to ensure that if something bad does happen where an exception is accidentally not caught for whatever reason, we can at least crash gracefully. I'm guessing that I will need to form my entry point completely in code, but am not sure of the proper way to accomplish this in WPF. Thanks. Just hook the Application::DispatcherUnhandledException event. HTH, Drew ...Show All

• .NET Development deserializing without loading assembly

  Hello! I'm working on plugin framework, where each plugin resides in its own AppDomain. Plugins are configurable. Configuration variables may be different for each plugin, but should be accessible from main application. I guess discovering plugin's config variables via Reflection would cause loading plugin's assembly into main AppDomain, which is what I want to avoid. My question is: is it possible to serialize object defined in assembly "A" loaded into some AppDomain and send it to another AppDomain (as byte[], string or XmlWhatever), and then deserialize it in that AppDomain without loading assembly "A" into it In my current implementation plugins store their configuration variables in Dictionary, thus making configuration via PropertyG ...Show All

• SQL Server Add runtime rows to sql express database

  Hi All, I have a c# project with an sql express database which is bound to a datagridview via a dataset. I would like to allow the users to import data into the database from a text file.

• SQL Server String Formating

  Hai .net team I am returning the value Eg. 1000.00 in my select query but i need to format that vlaue like 10,00.00 by putting comma in to that value how to achive using sql server 2000 thanks sujithf You should do formatting on the client side. It is easier to handle it there due to richness of the formatting built-ins or methods. You can do this in TSQL also to some extent if you convert the value to money and use CONVERT style like "convert(varchar, cast(1000.00 as money), 1)". But this has few limitations since the range of money / smallmoney may not be sufficient and you have no control over the formatting rules. ...Show All

• Software Development for Windows Vista Dual layer

  Does IMAPI support writing to DVD dual layer Are there any example clients for that for both files and ISO image burning (for ISO images there's a DVDburn tool at nt resource kit, but not sure if it supports vista) You are able to use Live UDF on DVD+/-R disks as long as you leave the session open. To eject the disc and still be able to continue adding content on DL discs, you need to disable session closing in the drive properties, Recording, Global Settings. If you leave the default option, Live UDF will work on blank media, but you will not be able to add data to DL discs after the first eject. ...Show All

• Visual Studio 2008 (Pre-release) ItemSource

  Hey everyone I have a question. I am getting my feet wet with the WPF and am wondering about the ItemsSource property that I see with some of the data bindable controls. I can see that it will bind to the control in populating the control with information. My question is are changes made to those items updated back to the object that was used. So for example if I had a generic list of strings that I was binding to a listbox, if I added a couple of lines to the listbox would a couple of string be added to my list Thanks Kenzie I've moved your post to the WPF/Avalon forum -mark Program Manager Microsoft This post is provided "as-is" ...Show All

• .NET Development XML is not visible in Internet Explorer 7

  XML documents are not visible when I try to open them with Internet Explorer on my desktop. The same documents are visible in Internet Explorer on my laptop. Why would XML documents be visible on one copy of Internet Explorer and not another. Netscape and Mozilla will open XML documents on my desktop. At this point I'm relegated with using Mozilla to work with and view XML documents when I'm working on my desktop. Mozilla is not my first choice of browsers, but it's the only workaround at my disposal at this point. I've checked the XML settings in Internet Explorer and they seem to be fine. Windows XP shouldn't be the problem, but there is probably some setting in the registry that needs to be changed. Does anyone have a suggestion ...Show All

• Visual Studio Relationship connector does not link

  I just started exploring DSL toolkit and ran into a strange problem. When I use any connector type from the toolbox, it does not link to any domainclass. Even if I use default model generated by MinimalLanguage template, connectors do not work either in DSL designer, or Debug sample solution. I use Visual studio 2005 Team Edition for developers, and Visual Studio SDK v3 release. I wonder if I should obtain VSIP license. Thanks in advance. A defect has been reported that connectors do not work from a toolbox which is floating. Is this the case You can dock the toolbox by clicking on the twisty (little down-pointing triangle) on the title bar of the toolbox and selecting "Dockable".

When trying to run the unmodified newly generated coded test, I'm getting this error: Error WebTest1Coded WebTests Could not run web test 'WebTest1Coded' on agent 'MachineName': Object reference not set to an instance of an object.
