Syntax

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

Parameters

Name Type Description
_maxwidth Integer max width of field; should be >= 4

Remarks

Use this method to prepare export field names to meet maxwidth criteria. Procedure will also perform basic name adjustment (remove non-ascii letter 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 exist, then the field will be renamed to nameXX (where XX means 00, 01 etc in hexadecimal).
