Hi list,

As the subject of this post suggest, i am in trouble with these components.

I read that TMemDataSet was similar to Delphi´s TClientDataSet as memory dataset. But i also read that people was using TBufDataSet instead of TMemDataSet.

What´s the best option if you want to work with memory datasets?

IMHO, bufdataset looks like an incomplete component. It does not have an option to "create dataset" as memds has. But what confuses me the most is the property editor accessed through context menu (right click component). We already have a property editor assigned to fielddefs and accessed in object inspector.

What exactly is this property editor for? Its option "Add fields" (ctrl+ins) always give me the error "Abstract Method Called", and the other available option "New" (ins), opens the New Field dialog with two possible options: "Calculated" and "Lookup".

But how this is useful if bufdataset do not have an "OnUpdateError" event published? It does not have an OnCalcFields event, so what is this "calculated" field for?

Please, if someone can clarify these doubts, i will appreciate. Or if someone can point me to a document or have a sample source using these components, i will appreciate too.

Thanks in advance.
