Many of us misses the old days when a character was represented by a single byte. These days we need to worry about codepages, character translations, and the works... Well Unicode chars came to our rescue and saved us from having to worry about all these stuff.
But, sometimes we need to represent a string as an array of bytes. The .NET Framework provides several encoding mechanisms: ASCII, UTF7, UTF8, Unicode. Did you notice something missing?
The good old ANSI. ANSI, to those who don't know it, is a super set of ASCII each char is represented by a single byte (range 0-255). ANSI Encoding is system dependent, but extremly efficient when handling with strings.
The class I'm providing fill this gap. It provides a fast way to convert from a string to an array of ANSI bytes.
Each char in the string (or char array) is converted to byte through Microsoft.VisualBasic.Asc function. So, I think it will be easy to understand.
It's multi threaded in order to acheive performance. In my tests I was able to convert an string about 1,000,000 chars long in less than 3 senconds.
*UPDATE* Fixed a little bug when handling strings and/ou byte arrays that was multiple of 256 in length. Added a Project Sample (along with a new status bar control)

Dude! I wonder how you only got an intermediate level rather than advanced.
I saw your code right above my binary typewriter and checked the picture and thought, "Wow! That's what I wan to do!"
I'll be filing through your code to see how in the world you made a rich text box do that.
5 outta 5
