Werte in dynamisch erzeugtem Form ändern

[waldforest]

Hallo,
ich erzeuge das Form wie folgt im Main

Delphi-Quellcode:

PROCEDURE TMain.CreateMyFormInplaced(CONST aFormClass: TFormClass; CONST Alignment: TAlign);
VAR
  NewForm  :  Tform;
BEGIN
  IF Assigned(aFormClass) THEN
    BEGIN
      NewForm := aFormClass.Create(Self);
      NewForm.Visible := False;
      NewForm.BorderStyle := bsNone;
      NewForm.Align := Alignment;
      NewForm.Parent := Panel1;
      NewForm.Show;
      NewForm.AutoScroll:=True;
      NewForm.Width :=Panel1.Width;
      NewForm.Height :=Panel1.Height;
      FreeAndNil(FCurrentForm);
    //  FCurrentForm.Free;
      FCurrentForm := NewForm;
    END;
END;

und rufe wie folgt auf

Delphi-Quellcode:

procedure TMain.JvOutlookBar1Pages0Buttons0Click(Sender: TObject);
begin
CreateMyFormInplaced(TDBUpdate, alClient);
end;
