I am currently writing an application for a computer microscope using TWAIN and I am testing the application using the microscope, the TWAIN sample source and my TWAIN/WIA webcam. None of them are fully functional at the moment. Oddly enough, the webcam seems to be a bit more functional than the sample source (in state 5, several buttons work, while the sample sources buttons don’t work at all). Is this similar to your experiences?
(I know something is wrong with the TWAIN part of my event loop. My guess is that the working buttons don’t use TWAIN commands, but work with WIA instead… but I am absolutely no expert in these matters.)
