The Changed property indicates whether any non-button field values in the window have changed.
window.Changed [= boolean]
• window – A window object.
• boolean – If True, a non-button field value in the window changed.
A field’s value changes when the user makes an entry in a field, or when the field’s value changes using VBA. In both of these instances, the Changed property will return True for the current window.
The Changed property is useful for determining whether the contents of a window changed, and performing an action based on those changes.
The Changed event for a field always runs whenever a new record is displayed in a window (such as when the user is browsing records using browse buttons). However, only the window’s Changed property ascertains whether the user actually modified the contents displayed in the window.
