This video demonstrates the use of the My Namespace in Visual Basic which provides a short-cut to often used classes in the .NET Framework Class Library.  We demonstrate how to use the My Namespace to retrieve information about the user's computer, search for files on the file system, perform file and directory manipulation, get command line arguments, work with application settings and more.

      Hello. First of all thanks for a great series. One question what happens at 12:31? The names shown in the console window show Brian and Chuck but the names assigned to the settings were Bob and Steve (11:44). Brian and Chuck were assigned later approx. 13:30...

      @Kari Holgarsson:  Great catch.  I think you caught me here pulling a slight-of-hand ... I actually ran through this exercise off camera once (a practice run).  I think the values were cached somehow -- perhaps those values were cached in the output directory (/bin) somehow.  I **forgot** about this otherwise I would have probably re-recorded it.  If you write the code yourself during this exercise, you will get the correct results.  Sorry for the confusion.  Sad

      Ok, thanks for the explanation ;-) I will try the exercise myself, I was just wondering if some values could be "stock" in memory (unable to update) as this could be very difficult to debug in a more complex code.
