• Disabling/removing the Team Foundation addin/extension in Visual Studio 2010?

  - by Lasse V. Karlsen

  I have an older laptop that I won't get around to replacing for another month or two. It has 1GB of memory so I'm trying to squeeze applications as much as possible. In Visual Studio 2010, it has apparently loaded some extensions related to Team Foundation Server, since I have menu items and dialog choices for it. Questions: Would I save a noticable amount of memory (even a couple of MB would be good) if I managed to disable this? How do I disable it?

• When would I want to model a class with a private ctor?

  - by dotnetdev

  Hi, I've seen plenty of classes in .NET which have private constructor (Stream is one of them I think). When would I want to model a class like this? I keep thinking that if my class has no internal state/fields, then I can make it have a private constructor. Am I on the right track with this idea? I can understand the use of a factory (I've run into the tipping point a few times), but not with a private constructor class. Thanks

• ASP.NET MVC: How to create a basic Pseudo Viewstate? Or better solution?

  - by Mark Redman

  I am newish to MVC and understand all the great things about it, including the reasons why voewstate isnt available, however there are some circumstances where I think having some kind of view state will be quite handy, In my case I am thinking about list pages with various search filters that can be applied to the list. Would it be worthwhile implementing some kind of pseudo viewstate to hold this info in some cases? or is there a better solution? Any examples out there? Your comments appreciated.

  I'm trying to use a dynamically generated fully-qualified table name in sql server 2008. For example, this does not work: select max([id]) from @dbName+N'.[T1]' This will give an error like: Msg 102, Level 15, State 1, Line 73 Incorrect syntax near '+'.

• Ajax "deselects" hyperlink under the mouse cursor.

  - by thealliedhacker

  I have a page that performs an Ajax request that replaces a div every second. This div also has hyperlinks in it. If the user tries to click one of the hyperlinks, it will work, but if they move the cursor over the link, wait for a second without moving the cursor, the hyperlink no longer has the "hover" pseudostyle and if they click at the wrong time, the link doesn't work. Is there a way to update the div without causing this, or to restore the "mouse over" state of the link?
