Reply To: Refreshing the data Source

Hi gabe
I have opted not to use TWAIN for this app in the end opting instead for Canons own SDk which does exactly what I want. The primary motivation for using TWAIN was not to have to rely on a propriatory SDK however its not essential.
FYI with regard to the logic of the app, essentially the user connects his or her camera to their computer and each time a shot is taken it appears on the monitor automatically with out the user having to leave their camera and download the image just taken. That may seem a peculiar thing to want to do as a user, however it is designed to capture images from cameras connected to clinical equipment or microscopes, telescopes etc. or even just studio shots.
The problem with just using IO calls would be that there is no feed back from the camera, so the app would not know if a new picture had been taken, hense the need to leave the datasource enabled, however this apparently does not update. Thankfully the SDK accomplishes this easily.
Regards
