• Visual Studio Team System Customization of test conditions?

  Hello everybody, IMHO list of test conditions for a Database Unit Test is too restricted, and of course I'd like to customize both list itself, and parameters in existing conditions. Is there any way to do it Hi Mark, results(0).DataSet.Tables(0).Rows(0)(0) It looks like the VB project could have better references added to it when a DBUnitTest is added to enable intellisense for the DataSet; I will look at adding that for the next CTP. In the meantime, if you could add a reference to System.Xml to enable intellisense. Remember, the DataSet is populated by results from the test execution, so it is possible to specify an invalid index into one of the above collections. If we were to add test condit ...Show All

• SQL Server Cube, Build, Deploy, Process

  Dear all, I'd like to get simple and clear explanation of the cube in data mining, and 3 notions we encounter a lot : Build, Deploy, and Process. (1) What is the cube that is created when we deploy a mining solution/project I wonder what type of cubes they are because although the dialog on deploy/process show that cube, after successful deployment we still don't see the cube in Cubes folder of the project. (2) Why the SQL Server created that cube Even though we process only one table and only use case-table (without nested table) (3) Can someone explain these 3 concepts with CLEAR differences between them (A) Build (B) Deploy (C) Process As far as I know, the stages are like that : build, then deploy, then process.

• SQL Server "Failed to load expression host assembly. Details: StrongName cannot have an empty string for the assembly name. "

  I previously had an ASP.NET 1.1 site running on my IIS 6.0 server ( not the default website) with Reporting Services running in a subdirectory of that website.  I recently upgraded to ASP.NET 2.0 for my website and was greeted with an error when trying to view a report.  The error was very non-descript, but when I checked the server logs, it recorded the details as "It is not possible to run two different versions of ASP.NET in the same IIS process.  Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process."   First of all, I could not figure out where and how to do this.  Secondly, I decided to try to also change the Reporting Services folders to run ASP. ...Show All

• .NET Development RSS data

  How can I decipher RSS data feeds with VBX 2005. Is there a component I can use Thanks. I would first recommend examining the RSS 2.0 specification so that you can familiarize yourself with the information a RSS feed can provide. If your requirements are simple you should consider using the .NET framework XML classes to consume the RSS feed data. If you need a richer conceptual model to program against, I have written a syndication framework that is available on CodePlex at http://www.codeplex.com/argotic that allows developers to read/write syndication feeds in both RSS 2.0 and Atom 1.0 formats, as well has OPML 2.0 documents, etc. I also want to point out that Microsoft in the Visual Studio Orcas ...Show All

We have a ASP.NET application, once a week we need to call a "create schdule" function from this application. This should have been in off hour process but we were not able to do this because of some business rules. This simply calls a stored procedure that will take approx. 1.5 hours to complete. When we call this procedure the SQL utilization becose 100% and then our simple query became unresponsive. Can we by some way tell this particular store procedure not to take 100% CPU, (sql server resouce), so if say some one ask SQL to get back with login credential this can be done when this sp is runnning..

• .NET Development Getting deleted child rows for a "SINGLE" parent row

  Hi, I have 3 related tables. First one is the parent and the other two are children of the first one. Ican navigate through parent and its children using DataGridViews and relations.
