We've
done this many times - I don't have the code with me ATM, but its in the
form:
function TForm1.GetDataset(AOwner: TComponent):
TClientDataset;
var
tbl : TClientDataset;
fld :
TField;
begin
tbl := TClientDataset.Create(AOwner);
with
tbl.FieldDefs.AddFieldDef do
begin
Name :=
'FirstField';
DataType := ftInteger;
end;
with tbl.FieldDefs.AddFieldDef do
begin
Name := 'SecondField';
DataType := ftString;
end;
tbl.Open;
.....
end;
You
can also set up the ClientDatasets in the IDE - just set up the FieldDefs only,
then Open.
If you
need more I can send you a working demo tomorrow.
Cheers

How do I setup a ClientDataSet as an
In-Memory Table ?
I have placed a TClientDataSet in the DataModule
there is no Provider and no File.
I have tried creating FieldDefs, Persistant
Fields, and both.
I want to be able to populate the Fields (many
rows) of the ClientDataSet - Do some heavy processing - then just clear
it.
I do not require any storage for the
Data.
The problem is that when I set the DataSet Active
- It blows up because there is no provider.
I have been told that this can be done - I am
starting to doubt it though...
