Prepare export field names.
Syntax
// C# public void PrepareExportFieldNames( int _maxwidth, bool _forced );
' VisualBasic Public Sub PrepareExportFieldNames( ByVal _maxwidth As Integer, ByVal _forced As Boolean )
// Oxygene public procedure PrepareExportFieldNames( _maxwidth : Integer; _forced : Boolean ); virtual;
Parameters
| Name | Type | Description |
|---|---|---|
| _maxwidth | int Integer | max width of field; should be >= 4 |
| _forced | bool Boolean | if _false (default) export names will be constructed for new fields; otherwise saved fields will be ignored |
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).
