Im busy creating some charts to go on my silverlight application and would just like to know what the .Series[0] represents in the following piece of code
PieSeries pieSeries = ((PieSeries)chart.Series[0]);
Did you check the documentation for the control you're using? What exactly are you having trouble with?
Sec, .Series[0] means to access the Series property, which is an array or list type or indexer, where you want to access the first (zero-based) element (0).

What is the formula for converting UPC-E barcodes to UPC-A barcodes? Better yet would be some C# code, C#esque pseudocode, or even just in an "English" expository way.
Ctrl+F for "Converting UPC-A to UPC-E" at http://www.taltech.com/barcodesoftware/symbologies/upc . It explains all the cases in a better format than I can paste here.

When an event is fired from an element on one tab, how can I have the handler switch the view to a different tab.
I am looking for how to do it in C# code, not xaml. I have done research and cannot find a c# solution.
TabControl.SelectedIndex = <Integer index of the tab you want to display in the 0-based Tab array>

I wonder how to get a string (or array of strings) between two known tags.
For example I have this string
string var1="my first video is [video]http://video.com/aaa[/video] and my second is[video id=\"1\" length=\"3\"]http://video.com/bbb[/video]";
How to get these values http://video.com/aaa and http://video.com/bbb?
use this pattern: #"\[video.*?\](.*?)\[/video\]" and then get group 1. I won't post the whole code because I dont want to do your work for you. Read about C# Regexes, Patterns and try to write your code with this pattern.
