This article presents classes that represent bitmaps in full managed code.
using System;

namespace Pfz.Threading
{
	/// <summary>
	/// Class that returns the value of DateTime.Now.Ticks when GetValue is called 
	/// but also guarantees that two calls will generate different values, even if
	/// they are done one just after the other.
	/// </summary>
	public static class TicksOrIncrement
	{
		private static readonly object fLock = new object();
		private static long fLastValue = DateTime.Now.Ticks;
		private static readonly Random fRandom = new Random();
		
		/// <summary>
		/// Gets a new DateTime.Now.Ticks value or a random incremented value if
		/// this is a call done at the same microsecond of the last one.
		/// </summary>
		public static long GetNext()

I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.
