Applies To: CursorAdapter Class

Visual FoxPro stores the value changes, which are used by CursorFill. The CursorRefresh method uses the value of the SelectCmd parameter, not the SelectCmd property. This facilitates construction of custom queries "on the fly". For example, you can store a basic SELECT – SQL command in the SelectCmd property and add a WHERE clause to the SelectCmd parameter in this event without changing the underlying value of the property. The value of the SelectCmd parameter is then passed to the AfterCursorFill event.

If the code in BeforeCursorFill returns a value of False (.F.), CursorFill does not execute, and the currently attached cursor remains unclosed. However, if the code in BeforeCursorFill does not return false, the currently attached cursor closes, and CursorFill executes.

Changes made to these parameters take precedence over the original values stored in the respective properties or that are passed to CursorFill.
