found this at http://www.gamedev.net/community/forums/topic.asp?topic_id=550283

very useful.

// If there is current text and it does not end in a newline, add one. 

if (!string.IsNullOrEmpty(outputWindow.Text) && !outputWindow.Text.EndsWith(Environment.NewLine)) 

{  

outputWindow.Text += Environment.NewLine; 

} 

// Append the text. 

outputWindow.Text += DateTime.Now.ToString(); 

// Set the selection to the end of the text, zero length. 

outputWindow.SelectionLength = 0; 

outputWindow.SelectionStart = outputWindow.Text.Length;

Lesson 1

1)Making a variable nullable

bool? mybool = null;

int? myint = null;

2)System.Drawing.Point p;

p.Offset() : translates the points by specified amount.

3)Console.WriteLine() will call ToString() Automatically.

4)String is a reference type not value type.

Lesson 4

Boxing converts a value type to a reference type, and Unboxing converts a reference type to a value type.

a very nice Photoshop tutorial
