Bug in Uri class?
I believe I have found a bug in the Uri class. I believe it is incorrectly
removing periods that appear at the end of segments in the path. The

{
const string urlWithoutPeriod =
"http://my.domain.com/top.level.folder/top.level.folder/my.cool.picture.jpg";
const string urlWithPeriod =
"http://my.domain.com/t...

WPF ListBox - cannot get to scroll automatically to bottom
Hi there,
I know this sounds simple, but how can you get a ListBox (in WPF) to

Thanks!

Help: "Not Responding" with splash screen on Vista
My app (.NET 2.0) has a very basic splash screen (borderless form) that I
load manually early in app startup. It works fine on XP.
On Vista, the app takes longer to load. In a few moments, the splash
screen is replaced with a blank form of the same size with a title bar,
which reads "<form text property> (Not Responding)". After a few moments
more the app continues normally.

operator overload for generic methods so I can do == and ++
I've got a method that I would like to turn into a generic that accepts
either an int or a long. However in the method I would like to:
a. test an instance of the generic type against 0 (or default(T))
and
b. increment an instance of the generic type.
Something like:
