ok, i dont' know how much people have gotten into this here...but i found two sites, one which you have to pay for, and the other is free/trial/pay. now if im not mistaken, twain seems to be some sort of set of files, or api's that make programming using a twain compatible device (usb camera, scanner etc...) easier. as far as i know its just used for devices that capture pictures. im not 100% sure on most of this stuff, so if anyone knows anything else i'd like to hear more about it. basically i was searching for a site that has good free twain dll's with sample source code. these are the two best that i found. if anyone has any other information on this topic it would be greatly appreciated.
