Hi meikl,
Can you help me more? I will award you more points.

How to show the Image(TDBImage field) by some conditions?
Now I have to drop a TDBImage on the form, and drop a TImage on the TDBImage. The code as following, I don't like this way.

procedure DataSetAfterScroll(DataSet: TDataSet);
begin
  if DataSetEventMessage.AsString <> 'Normal' then
  begin
    EmpNoEdit.Text := '';
    EmpNameEdit.Text := '';
    Bitmap := TBitmap.Create;
    try
      with EmpPicture do  //EmpPicture  is TImage
      begin
        Bitmap.Width := Width;
        Bitmap.Height := Height;
        Picture.Bitmap := Bitmap;
      end;              //Clear the Image
    finally
      Bitmap.Free;
    end;
    end
    else
    begin
      EmpNoEdit.Text := DataSetEmpNo.AsString;
      EmpNameEdit.Text := DataSetEmpName.AsString;
      EmpPicture.Picture := DataSetEmpDBPhotoImage.Picture; //EmpPicture  is TImage
    end;
end;

about the timage to clear

EmpPicture.Picture.Assign(Nil);
(thats just from head yet)

this should replace this code
----
try
     with EmpPicture do  //EmpPicture  is TImage
     begin
       Bitmap.Width := Width;
       Bitmap.Height := Height;
       Picture.Bitmap := Bitmap;
     end;              //Clear the Image
   finally
     Bitmap.Free;
   end;
----
