Re: [DUG]: Adding Calculated Field

[Rohit Gupta]

Clientdataset is a different beast.  you can create any dataset you 
like.. but its not the same as the one on the disk... unless I add 
another 4/5 more components to feed it..... that remains the 
sledge-hammer approach.  :-)  And almost forgot... it doesnt work with 
int64s

from the delphi help....

The following code creates and activates a client dataset in the 
form's OnCreate event handler:

procedure TForm1.FormCreate(Sender: TObject);
begin
  with ClientDataSet1 do
  begin
    with FieldDefs.AddFieldDef do
    begin
      DataType := ftInteger;
      Name := 'Field1';
    end;
    with FieldDefs.AddFieldDef do
    begin
      DataType := ftString;
      Size := 10;
      Name := 'Field2';
    end;
    with IndexDefs.AddIndexDef do
    begin
      Fields := 'Field1';
      Name := 'IntIndex';
    end;
    CreateDataSet;
  end;
end;
i think that is..
