• Visual Studio Team System Why ClassInitialize functions need to be static.

  I'm working in C++.  I'm not sure I understand how the XXXInitialize/Clean attribute is supposed to work. The ClassInitialize method is called before the class is created (the function need to be static).  The TestInitialize is called before each tests.  I need a way to Initialize/Cleanup class member.  When I tried to put this initilization in the class constructor, I discovered the constructor was called many time ( ).  The desctuctor is also never called, so I don't have a way to do clean up. This mean (if I understand well), I'll have to use static variable (ouch!) inside my class if I want to initialize it.&nbs ...Show All

• SQL Server SQL Server Management Studio Express: Missing DataBases from VWD Project

  LOST DATA BASES I appear to be doing something stupid! I created a VWD express project that contains a database. In VWD the DB application works fine. I can see all my tables. VWD stores the DB in the applications area of MY DOCUMENTS in a project folder under “SQL SERVER Management Studio Express”. However, when I run the SQL Server Management Studio Express, I get a instance of the “(computer_name)SQL\express” that contains the System DB, but not the DB that I developed in VWD. After investigating I found the SQL DB for the Studio Express under MY COMPUTER, “Microsoft SQL Server” in a subfolder under "MSSQL" folder. Mi ...Show All

• SQL Server IN Clause

  Not sure if this is the right forum for such a query... please feel free to inform me where can I put up such a query if I am wrong. Why is IN clause considered highly expensive Special thanks for comments with examples. Sure this is the place. I guess the first question I have is why do you think it is considered expensive Sometimes these kinds of ideas come from a past version of SQL Server (I know people who still follow the same rituals because of bugs in 6.5!) If you mean using WHERE IN (select value from table), then often using an EXISTS is probably better, but in most cases they can be compiled to the same plan int ...Show All

• Visual Studio Team System In Web Tests, How to Validate the values on a grid ?

  I want to validate the values that are shown on a grid , based on the values that are selected on a Combo.(Herein internally, the grid gets filled, when the combo box value is changed.) I would also like to know the selected row from the grid, so as to try it... or else Manual testing has always been there at our help   You can do this with a validation rule.  If the value in the combo is displayed on the same page as the grid, then you could do it with one valistion rule.  If the value of the combo is on the previous page, then you would need to use an extraction rule to pull out t ...Show All
