Retrieves a pointer to the event handler function associated with the ondatasetchanged event of the document.
Syntax

Parameters
- p
- Address of a VARIANT structure that contains a pointer to the event handler, or NULL otherwise.
Return Value
Returns S_OK if successful, or an error code otherwise.
Remarks
Use the following code fragment to obtain an event handler.pBody->get_onEvent( &_variant_t(pDisp) ); // pDisp a pointer to an IDispatch interface // pBody a pointer to an element of interest
Sets a pointer to the event handler function associated with the ondatasetchanged event of the document.
Syntax
HRESULT put_ondatasetchanged( VARIANT v );
Parameters
- v
- VARIANT structure that contains a pointer to the event handler to set, or NULL otherwise.
Return Value
Returns S_OK if successful, or an error code otherwise.
