For the DataSetClassHelpers.dproj project, let's start to talk about the simpler helper—the SaveToCSV method.
The current compiler implementation of class helpers allows only one helper active at a time. So, if you need to add two or more helpers at the same time, you have to merge all the methods and properties in a single helper class. Your TDataSet helper is contained in the DataSetHelpersU.pas unit, and is defined as follows:
TDataSetHelper = class helper for TDataSet public procedure SaveToCSVFile(AFileName: string); function GetEnumerator: TDataSetEnumerator; end;
To use this helper with your TDataSet instances, you have to add the DataSetHelpersU unit in the uses clause of the unit where you want to use the helper. ...
