DataSetBrowser.Show(pDataSet : TDataSet);

I've never written a component, so I would
appreciate any hints as to how I'd go about
turning the form into a component.

1. make your pDataSet as a published property, so it will be displayed
in the Object Browser.

TDataSetBrowserDlg = class(CommonDlg)
  private
    FDataSet: TDataSet;
  ...
  published
    property DataSet: TDataSet read FDataSet write FDataSet;
  ...
  end;

2. Foresee a public procedure Execute, to be used in your code at
runtime, like

procedure TDataSetBrowserDlg.Execute
begin
  ...
  with TDataSetBrowser.Create(Self) do
  begin
    pDataSet := FDataSet
    Show;
  end;
  ...
end;

3. Make sure your TDataSetBrowser handles the whole lifecycle of your
dialog, including Cancel/OK buttons

Good luck, Joeri

TNVC=class(Component)
  Procedure Show(DataSet : TDataSet);
end;

...

Procedure TNVC.Show;
begin
  With TMyForm.Create(Application) do try
    DoSomeSetup;
    ShowModal;
  finally
    free;
  end;
end;

And then make sure a copy of your form is not in the project auto-create
list.
