Common Objects


The state of the data source object. 

Read/Write property
Type: boolean

- the database resource is ready to be used through other methods of the data source object. 
False -
the data object is not ready.

You can set this property to false to forcefully invalidate the data source. This is more efficient than setting a scope expression which yields a zero record set in the case when no records need to be shown.


   If DS.valid Then DS.Create    ' check if valid
   DS.valid = false              ' invalidate
