ImageGear .NET
User-Written Checking

User-written checking is performed through the ImGearRecZone.CheckWord Event by the integrating application. When creating or updating a zone, the ImGearRecCheckWordEventArgs.CheckWord Property of the zone may be used to register an event listener for the CheckWord Event. During recognition, the CheckWord Event is fired, and the user-written event handler is passed the string to be checked and the index of the zone (from which the string to be checked is derived). The user-written event handler should evaluate the string, knowing the pattern of permissible zone content. Its opinion on the recognized string's acceptability should be expressed with one of the five values from the ImGearRecCheckWordOpinion Enumeration.

Asian Recognition Module: The checking subsystem is not available. This means spell checkingUD-Checking and User-Written Checking cannot be used when the Asian Recognition Module is active. See the Asian Recognition Module topic for more details.

See the C# Recognition sample for a demonstration of how to handle the CheckWord Event.
