• Software Development for Windows Vista Persistence service

• Visual Studio Team System Long running time for "Dispose Methods should call base class Dispose()"

  Hello, I've been invesitgating the performance of FxCop and came across an anomalous performance on the rule "Dispose methods should call base class dispose" (Microsoft.Usage#CA2215). One two different assemblies (Spring .NET framework, and SharpDevelop), this rule takes orders of magnitude longer than other rules. About 6 seconds on Spring, and roughly 20 seconds on SharpDevelop. Most other rules I looked at run in less than half a second on these codebases. I am using the commandline of FxCop version 1.35, build 51212.0. Does anyone experiance similar performance problems with this rule Is there an explanation for why this is so ...Show All

• .NET Development Using Session state to store objects

  Hi I want to save an object, and make it available over several pages. So far it seems the best way for me to do this is to use sessions. However I can't find a way to store an object for the duration of a session. Below is some of the code Fragment of Method 1 SearchResultCollection ownerResults = Code to return SearchResultCollection Session[ "ownerResults" ] = ownerResults; Fragment of Method 2 SearchResultCollection ownerResults = Session[ "ownerResults" ]; However, I get the following error.

• Visual J# java (J2EE 1.4) convert to J#

  Hi, I want to convert my application in java (J2EE 1.4) to J# with minimum changes. Where can I get the script Thank's Alexei (I have tryed JLCA 2.0, 3.0 and it gives me about 100,000 errors becouse it convert to C#. I don't have a time for working on errors. I read that Java can be converted to J# with minimum errors.) Generally my experience doing this always leads me to running the J2EE code under Object Web or JBoss's free J2EE server and building either a webservice or RMI invocation layer to bridge the .NET code. This does assume that you have a good MVC design where you can easily seperate the backend J2EE components from t ...Show All

• Visual Studio 2008 (Pre-release) Anybody managed to find a workaround for the "Black Window" bug in the Nov CTP?

  I think I'll create this post as a checkpoint where people can post any info on this bug. For a background, some of us using the November CTP for WPF and either Visual Studio 2005 or C# Express, are experiencing a black window when running the simplest of WPF apps (i.e an app that does nothing but window.Show()). Other people experience it intermitently in XamlPad itself. A few links to the problem... [1] [2] Apparently the January 2006 CTP contains the same bits for WPF (Avalon) as the December 2006 CTP, so the same bug will be present. The Microsoft product feedback centre states that the fix will be ...Show All

• Windows Forms DataColumn.Expression - automatically updating values in controls

  My application has a DataSet with a table that has a set of columns with default values and some columns with expressions based on the other columns. Using a form bound to those columns the user should be able to edit the default values and see the values in the controls bound to columns with expressions update instantly. What happens, though, is the application starts and the controls display the default values and expression-based values correctly. However, when I change the default values, the expression-based values do not change. How do I get the controls bound to expression-based columns to automatically update their values when the va ...Show All
