From: Dave Froble on 2 Dec 2005 15:11 I tried looking in the archives, but I'm rather poor at searching, so I'll ask. The subject pretty much describes my question. I want to scan from within a VB project, and don't have any idea where to begin. Any and all help would be appriciated. -- David Froble Tel: 724-529-0450 Dave Froble Enterprises, Inc.

Another way is to use an OCX. Apparently many versions of Windows have one included. On my system here I have one by Kodak called IMGSCAN.OCX officially described in Project/Components as "Kodak Image Scan Control". However, it works with all TWAIN devices installed on my system (flatbed scanner, film scanner, various digicams, etc). However, it only provides a very basic scanner support. As CSM1 says, it's far better to directly access the TWAIN module supplied by your scanner manufacturer. The drawbacks are that you will probably need the SDK (software developer kit) to make full use of it and the interface is usually geared towards C which means having to write "wrapper code" so VB can talk to it. On the plus side you will then be able to use all additional features unique to your scanner which may not be a part of standard TWAIN specifications. Don.

I'll take a look at the Kodak control. I don't need anything fancy. The applications is thus. Certain documents on 8.5 x 11 paper need to be scanned and placed into files. A database record is created to point to the file. Thus, a user can pull up and view any documents associated with a transaction. Plain black & white images are totally adequate. Thanks for the tip. A quick google search revealed that there are vendors with twain controls. Haven't had a chance to look at any yet. -- David Froble Tel: 724-529-0450 Dave Froble Enterprises, Inc.

For example to show available TWAIN devices with the Kodak one all you do is: ImgScan1.ShowSelectScanner This pops-up a list box will all installed TWAIN drivers highlighting the one currently selected. Other functions are similar one-liners and it's all explained in the help files. >Thanks for the tip. You're most welcome.
