add new field to kbmmemtable

pele

I would like to use a kbmmemtable in report.
kbmmemtable is on form in delphi. I can read all fields and records
But I have a problem with add new fields to the dataset.

I tried to do like this:

var dataset : TDataSet;
begin
   dataset := TDataSet(Report.GetDataset('kbmMemTable'));
   dataset.FieldDefs.Add('Age',ftInteger,0,True);        <--- Acces Violation
end;

and now how to add new fileld into dataset ?
Is it possible?



Or, how to create internal dataset with I can dynamically append new rcords in runtime and the dataset shoud be visible as datasource for MasterData band?

gpi

Try to create user function, call it and add a field to kbmmemtable in the Delphi's code
