public class AutoFormsProgressEventArgs : EventArgs This event is fired when recognizing and processing a form, or when generating form attributes. The Percentage Property is not meaningful during recognition operations since the engine does not necessarily need to compare the filled form with each master form in the repository. Once the engine finds a match, it will stop searching and return.
This event also allows the user to cancel engine operations using the Cancel property
