Data


Unit: SDL_geodb
Class: TGeoDB
Declaration: property Data[DBEntry: longint]: TgdbData;

The read-only array property Data provides access to the data of the database. A detailed list of the available data can be found in the TgdbData description. The index DBEntry specifies the database entry and may take values between 1 and NumEntries.

Hint 1: Please note that the Data array contains only the "basic" data of a database entry. Depending on the sub-property ItemKind there may be additional information available (i.e. BLOBs or polygon data). Use the method RetrieveBLOB to retrieve any additional information.

Hint 2: In order change any items of the Data array you have to use the method UpdateBasicData.

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): geodata
