DK11 for Delphi | GisLayerVector.TGIS_LayerVector.PrepareExportFieldNames | Overloads | Constructors | Fields | Methods | Properties | Events

Prepares field names to export.

Available also on: .NET | Java | ActiveX | Python.


// Delphi
  procedure PrepareExportFieldNames(
    const _maxwidth : Integer;
    const _forced : Boolean
  ); overload; virtual;
// C++ Builder
  virtual void PrepareExportFieldNames(
    const int _maxwidth,
    const bool _forced
  ) /* overload */;


Name Type Description
_maxwidth Integer max width of field; should be >= 4
_forced Boolean if _false (default) export names will be constructed for new fields; otherwise saved fields will be ignored


Use this method to prepare an export of field names to meet maxwidth criteria. The procedure will also perform basic name adjustment (remove non-ascii letters, etc.).

If a field name is empty, then it will be named to 'FIELD'.

If first letter of the field is not alphanumeric, then the first letter will be changed to 'F'.

If a field is longer then a specified value, then the field will be truncated.

If a field after such changes already exists, then the field will be renamed to nameXX (where XX means 00, 01, etc. in hexadecimal).
