Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, path names, dummy URLs, user input, and Twitter handles. Here is an example: "You could then declare a BaseDragDropManager class to be used in the DragDropProperties 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.

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The Cancel button has been declared in the second row and column."
