Would it be possible to download the older 5.2.2 database demo source ?
Thanks.

Hi

The source for the database demos should not have changed sice 5.2.2 (apart from adding some new demos). Can you explain your requirement?

I am trying to compile the database thumbnail viewer and it chokes on the Tiedbmultibitmap. It looks like that was not part of 5.2.2 but I could be wrong

Hi

The DBMultiBitmap demo did not exist in v5.2.2 (because TIEDBMultiBitmap did not exist). You should use the DBMView demo instead.

This demo will be in under \Demos\Database\ where you installed ImageEn.

Tried the demo you mentioned and i get an error there:
ImageEnMView1.ImageBottomText[ Index ] := Table1.FieldByName('Name').AsString;

It says that it is a readonly property.

Oh well.

Yes, that changed.

But if you have v5.2.2 installed, then you should also have the v5.2.2 demos installed.

Otherwise, change that line to:

ImageEnMView1.ImageBottomText[ Index ].Caption := Table1.FieldByName('Name').AsString;

Thank you. The demo did not really help. I am going through the database demo to see which one may help.
I am trying to have a horizontal thumbnails of images from a database that when i click on a thumbnail, it will open in an imageenvect component.
Thanks.

That should be relatively simple, what problems are you having?

procedure TForm1.ImageEnMView1ImageSelect(Sender: TObject; idx: Integer);
begin
  // When an image is selected, display it in a TImageEnView
  ImageEnMView1.CopyToIEBitmap( ImageEnMView1.SelectedImage, ImageEnView1.IEBitmap );
  ImageEnView1.Update();
end;

Hi

Not in v5.2.2. In the newer versions you can use TIEDBMultiBitmap:
