  I want to create some functions that operate only on the numeric types but I don't particularly care what those types are. I'd rather rely on the invoker or .NET's automatic casting rules to create the answer in the appropriate type.

Is there a way to make a function generic yet restrict its parameters to nume ...Show All

• Visual Studio Team System How to view submitted changesets?

  When a file is checked in, it is part of a changeset (very similar to a changelist in Perforce).  What I don't see in Team Foundation is a way to view previously submitted changesets (this is available in Perforce and is very useful). Is there a way to retrieve a list of submitted changesets, this seems like very basic functionality Since the changeset groups changes to multiple files logically, it often makes more sense to review the ove ...Show All

  Hi all, I am using Excel 2003, VSTO 2005 and C#.NET 2005. I am creating an Office Addin and a Smart Tag DLL. Some of the Actions in the SmartTag DLL require me to launch a Windows Form.

  Have just installed and registerd VB Express. I received an email with a link to the registrations benefits page ( http://go.microsoft.com/fwlink/ LinkId=52054 ).
