Display thumbnail view of an image

[rgrayclamps]

How do I display thumbnail view of an image in a VB form (VB6.0)?

Thanks,

Load the image file into an image object on the form.
Set Image.Autosize false and then you can set the height and width.

Hi, FrancisL:

Thanks for your repsonse! I can display a picture through an image object on VB form. But I do think this is an efficient way to display a preview (a thumbnail view).

Image controls are quite efficient for most purposes, you can use an array to show many images too.
There are of course many other ways, but I don't know enough about your application to be more helpful.

I have a very simple database program for pictures using VB6.0. I would like to display a thumbnail view as I navigate through records. Most image software, including Windows Explorer, have ability to show pictures in thumbnail view. I do not think they load entire images to image control object.

Thanks,

Alex

The first time you open up a folder containing pictures in Windows explorer, it creates thumbnail images and saves them to a file (thumbs.db if I remember right, and I think it is a hidden file by default). The next time you open the folder, the thumbnails show up quickly since they have been cached.

So, using FrancisL's suggestion you could load the picture to an imaging control and save the image at the new (thumbnail) size for later use.

I think they probably do. Have a look at my software, ControlDraw - it is is in part a database containing images.
