onUnadvise

Topic group Related topics Example

Event fired after dBASE Plus is requested to stop notifying the client application when a dBASE Plus data item changes.

Parameters

<item expC>

The data item for which the external application no longer wants to be advised when changes are made.

Property of

DDETopic

Description

Use onUnadvise in a DDE server program to respond to a request to cancel a hot link.

dBASE Plus automatically maintains an internal list of all clients that asked to be notified on changes in a particular item, and will automatically remove a client when the client calls their equivalent of the DDELink object’s unadvise( ) method. This makes onUnadvise supplemental. If you have been doing your own tracking in an onAdvise event, you will want to undo that in the onUnadvise event handler.
