onPeek

Topic group Related topics Example

Event fired when a client application tries to read an item from a DDE server application.

Parameters

<item expC>

The data item the client application wants to read.

Property of

DDETopic

Description

Use the onPeek property to send a value to a client application when the client application makes a peek request.

The onPeek event handler must RETURN the value of the requested item. dBASE Plus automatically handles the internal DDE mechanism to pass the value back to the client.

onPeek is also called implicitly by the DDETopic object’s notify( ) method so that the DDE server can send an item’s name and value when it is changed.
