Prepares field names to export.

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

// Delphi
public
  procedure PrepareExportFieldNames(
    const _maxwidth : Integer
  ); overload; virtual;

// C++ Builder
public:
  virtual void PrepareExportFieldNames(
    const int _maxwidth
  ) /* overload */;

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).
