TDBDataSet.Handle Property

Specifies the Borland Database Engine (BDE) cursor handle for the dataset.

Pascal
property Handle: HDBICur;
C++
__property HDBICur Handle;

Use Handle only to bypass TDataSet methods and call directly into the BDE. Many BDE function calls require a cursor handle parameter. Handle is assigned an initial value when a dataset is opened. If used with a BDE call that changes the current record position, call Resync immediately after returning from the BDE call. 

TBDEDataSet allows the Handle property to be set to an existing BDE cursor handle. Setting the Handle property is intended primarily for internal use. Descendant classes redeclare the Handle property to re-establish it as a read-only property

Note: Do not use this property unless an application requires BDE functionality not available through built-in components.
