For the applications that operate in Windows Vista (or later) or in Tablet PC, you have the ability to include the "Handwritten input (PC tablet)" option. This option allows the user to directly type the text in the control with the stylus or with the mouse. This feature is available by default in the applications that operate on Mobile.
