Previous Next

Actions exposed by native USoft Developer objects relate to the following use cases:

Manipulating controls

Manipulating windows

Providing help

OLE/ActiveX Container actions

Some actions appear in more than one functional category.

IMPORTANT: For Post-change, Pre-insert Validation, Pre-update Validation, and Pre-delete events, avoid calling actions that change data on the screen or in the database. This can cause looping when one event triggers another, which in turn triggers the first, and so on. Try to keep the activation of events in the hands of the user as much as possible.
