Scanning using WIA question

[Guest]

Here is my problem

I have written a proof of concept using VB.NET and Windows Image Aquisition libraries to operate a scanner, scan an image, and save it to a database (and retrieve of course). I have this up and running

However, I am using the CommonDialog object. This does not have any settings that let the scan area or DPI resolutions, etc be saved from scan to scan. Ideally, I would like to have the scanner perform the scan without any user interaction. I don't want the user to be able to modify the DPI and color settings at all. I would also like to provide document templates in my app that define the type of document that is being scanned, so that the scanner saves time by only scanning the relevent portion of the document

The group of people that will be using this app are very error prone, so I want to take as many decisions away from them as possible

Does anyone know if this can be done using WIA, or will I need to dig further into talking directly to TWAIN.
