Hi Boban,

If the target is windows 98 you can use the wang/kodak imaging controls. These are ocx's that you can drop on your forms.

If they're using ME or XP and NEWER scanners, you can use WIA (windows image acquisition). Search for it on MSDN. It's a bit more complicated than kodak, but works quite nicely - I did a presentation on this last year.

If they're using older (twain) scanners with xp, you will need to use a third party ocx (leadtools) to do this.

Putting images in fields isn't a good idea as it may generate tons of traffic on your network. The approach I use (which seems to be the de-facto standard) is to store the images as files and then just keep the file names in your fields. That way you only have the images travel through the network if the user needs to look at them.

Have fun!

Alex
