Hi there,

I just cain't figure-out how ot add a calculated field to a TTable
component at run-time. I've tried setting the table object as the owner
of the calculated field ( NewField := TStringField.Create(TheTable) )
and I've tried adding the field via the FieldDefs property (
TheTable.FieldDefs.Add(...) ). I must be pretty far off!!

Can someone hint me into the right direction, please??

Thank you all!!

Oliver.

here is an example.  but remember you still have to have code in the
OnCalcFields event of the ttable to use it.

Table1.Active:=false; // Must be false to add Fields to the Dataset
  Table1.FieldDefs.Update; // Make sure we have the latest Fields

  Monthly:=TFloatField.Create(Table1);
  Monthly.FieldName:='Monthly Salary';
  Monthly.Calculated:=true;
  Monthly.Dataset:=Table1;
  Monthly.DisplayFormat:='$#,0.00';

  Table1.Active:=true;
