• SQL Server data mining and SS05

• Visual Studio Team System Customizing Code Analysis

  Hi, I understand that you can customize the code analysis for a specific project. However, I've been asked 2 questions and do not know how to work it out: Can the configuration made by someone in a specific project be exported to a different project Is it extensible so that internal coding policies be checked And if so how can I do this Thanks, Luis Luis, There is no UI available that allows rule selections to be copied between projects (unless you are using Team Foundation and Code Analysis policy), however, if you use a text editor to edit the project files (.csproj/.vbproj), ...Show All

• SQL Server Slow execution of queries inside transaction

  I have some VB.NET code that starts a transaction and after that executes one by one a lot of queries. Somehow, when I take out the transaction part, my queries are getting executed in around 10 min. With the transaction in place it takes me more than 30 min on one query and then I get timeout. I have checked sp_lock myprocessid and I've noticed there are a lot of exclusive locks on different objects. Using sp_who I could not see any deadlocks. I even tried to set the isolation level to Read UNCOMMITED and still have the same problem. As I said, once I execute my queries without being in a transaction everything works great. Can you help ...Show All

• Windows Forms How can I make my forms move faster ?

  Dear .NET I have a C# solution on .NET v2 that has a GUI project in it, The Forms are defined as "global" static objects on the Main() so that I will B able 2 use them from anywhere through MainApp.MyForm.Is_Flag_On; I start the application from the Main() like this: Form_Main = new GUI.
