In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "There are two other useful properties declared by the Grid class."

A block of code is set as follows:

public string Name
{
  get { return name; }
  set
  {
    if (name != value)
    {
      name = value;
      NotifyPropertyChanged("Name");
    }
  }
}

Any command-line input or output is written as follows:

System.Windows.Data Error: 17 : Cannot get 'Item[]' value (type 
'ValidationError') from '(Validation.Errors)' (type 
'ReadOnlyObservableCollection`1'). 
BindingExpression:Path=(Validation.Errors)[0].ErrorContent; 
DataItem='TextBox' (Name=''); target element is 'TextBox' (Name=''); 
target property is 'ToolTip' (type 'Object') 
ArgumentOutOfRangeException:'System.ArgumentOutOfRangeException: 
Specified argument was out of the range of valid values.

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The Cancel button has been declared in the second row and column."
