I have been using a library to scan, located here, and have not been getting a consistant return. When I use the TWAIN Source, the GUI pops up and disappears almost instantly. When I tell the source manager to not show the GUI, it scans fine, but with duplexing enabled. When I scan with the WIA source, everything is fine.....BUT! I can't save my scan settings. Has anyone used twain or WIA in .Net and knows how to pass in the parameters for the scanning process? I have dug through WIA and TWAIN documentation, and neither of them are very helpful on the situation.
