Is there a DateTime like object in .NET that handles UTC also? That is, the
object contains the timezone and can properly compare between them.
Or how does one go about handling them if not? My info is
date/time/UTC(like, say +2:00 (EST)) and I want to do the least amount of

I would appreciate if anybody can provide some links/suggestions/
guidelines on how to go about handling the below scenario (i tried
looking the net, reading about MAPI, but not sure if it's applicable
with ms2007 and C#/vs2008 setup).

I create the timer like this:
           StreamingTimer = new System.Timers.Timer();
           StreamingTimer.Elapsed += new
System.Timers.ElapsedEventHandler(StreamingProc);

I'm writing an application which basically takes images from pixelink
camera and does some calculations on them.
I need to monitor the status of the system for 2 things: presence of
camera and connection to SQL server.

I'm looking at some old C# code and I found a line where a SortedList is
being accessed with a negative index, like so:
groups[-1];
My C# skills must be getting rusty.  How can that work?  What does it do?

    I have a list object called "myList" with the first item a string and
the second a DateTime. Something like this:
"some text 1", 19/03/2008 12:56:36
"some text 2", 19/03/2008 10:56:36

Is is safe to use Thread.GetNamedDataSlot  function inside a ASP.Net
application?
I am afraid if IIS manipulates the threads and my DataSlot is lost in that.
Thanks.

I have written a sample async code (using callback/async).
I am now seeing a situation where-in if two messages are received at
the same-time, both of them show-up in the data-buffer.
Given that i am new to this, can you point to resources or suggest

I have created a c# application where I have successfully created a
System.Diagnostics.Process and set the parent to be a GUI Control so
the process is embedded in the panel and looks like part of my
software application.

Until recently, I had been developing on an XP machine.
Updated to Vista as the development environment and now
when I try to access a file that I need to load I get an
UnauthorizedAccessException

Does any one know how to caputer text data sent to a printer to a file. I
have seen a window service that captures text data sent to a printer on the
server and save it to a file. I would like to know how to do this. I have
many reports that are produced on an IBM mainframe as ...

I'm almost positive that this isn't possible in C#, unless there's something
REALLY esoteric I haven't come across, but I was curious why something akin
to multimethods in Lisp isn't possible in C#.  Specializing function arguments
by type is useful, but sometimes it would be ...

I'm frequently using generic lists to represent child lists in my current system, and often require a bi-directional
link between them (so a child knows it's parent as well as the parent having the list of children.)
Currently I'm providing a "new" implementation of Add() and ...

Can someone, please, tell me what is wrong
with this code?! I get stuck on the "set"
method of the property.
public class Start

I need to generically detect changes in any object from one point to the
next.  I can't modify the objects, nor can I use traditional serialization
because the attributes aren't present and would be too slow anyway.
My current approach is to recursively traverse a given object ...
