Question

Is it possible to create and use a TClientDataSet inside an Object at runtime?

I like to make several changes in my Table and have those all Applied at the same time in cache like way, and TClientDataSet lets me do that. Know when I want to do this I have to build a TForm.

Is it Possible?

UPDATE

Can it be used, and How, without TDataSetProvider, and no TSQLQuery ? Because I tried it and it gave me an error no Provider!!

Components are just classes, and you can use them likewise:

procedure TMyObject.DoSomeDBStuff; var   localClientDataset: TClientDataset; begin   localClientDataset := TClientDataset.Create( );   try    finally     localClientDataset.Free;   end; end; 

You can also make a clientdataset-property if you like:

type   TMyObject = class   private     FClientDB: TClientDataset;   published     property Dataset: TClientDataset read FClientDB;   end; 

Some visual components may require a visual parent though, but for TClientDataset there should be no such requirement.
