Implementing Annotation Security
Note: This topic is for Document/Medical only.
LEADTOOLS provides annotation security through a number of properties, methods AnnLock method and AnnUnlock method let you lock and unlock annotations using a key. Locking an object through the automated mode generates an AnnLocked event and unlocking an object through the automated mode generates an AnnUnlocked event. If AnnShowLockedIcon property is set to VARIANT_TRUE, any locked object will be drawn with a padlock icon on top of it. AnnGetLocked method also provides a means of determining if an object is locked.
You can also secure annotations by using AnnSetUser method. By setting the user for an annotation, modification to the annotation cannot be made unless the correct user is known.
