TProvider Component vs. Provider Property

Question:

What is the purpose of the TProvider component vs. the
Provider property of the dataset?  When would the
TProvider component be necessary?

Answer:

The Provider property of the dataset is an interface of

type IProvider.  A TProvider is not required, you can just

use DataSet.Provider. Look at TDBDataSet.GetProvider for

how it gets the IProvider.  TProvider is useful, if you

need any of the events.



This example will open a client dataset looking at a TTable

on the same form.





uses BDEProv;

...

procedure Button1Click(Sender: TObject);

begin

  ClientDataSet1.Provider := Table1.Provider;

  ClientDataSet1.Open;

end;
