c#, vb.net or other?
2003 or 2005?
if you havent read the 1.9 spec, read it. read it a lot.
any specific scanner hardware being targeted? any specific OS targeted?
the hardware specific questions are (i think) rather important, as if you’re only tasked with writing an app to manipulate the settings covered by the twain spec you’ll be alright, but a lot of the manufactures have custom capabilities, custom operations, and custom return codes. i think writing an app to be competely hardware agnostic and still offer complete device manipulation is a rather large request (or maybe your project timeline is just massive – or perhaps you have massive resources available)
Are you looking for an off the shelf library, or are you planning to write the twain_32 wrapper as well?
Are you trying to run the twain device from a winform, webform or service? Have you taken a look as WIA2?, it could be (depending on the scanner and OS you’re targetting as not all hardware or OSs support WIA2)
There exist several rather decent twain librarys around, most for just a few hundred dollars. Not that I’m trying to talk you out of writing your our library (i am).
What setting are you trying to manipulate?
If you don’t mind my asking, whats the project timeline, how much do you have implemented so far?
Sorry if I appear to ask more questions than i answer, but i think this will come to a point rather soon, if you answer them all.
