Hi I have an application running TWAIN with the Data Source UI not shown, when the user clicks Aquire the last image from the connected Digital camera is downloaded.
Is that what you want to happen?
1. If the Data Source is left enabled and the user takes a new photo the data source does not register this new photo.
Why is the data source left enabled?
2. If the user clicks Aquire when there are no photos in the camera memory then Enabling the DS fails, i.e. it is not possible to enable the DS with the UI hidden when there is nothing to transfer.
Huh. So rc=failure. Mostly curious just (as I havent got a clue why you’re seeing this) but what is the cc?
What device are you using?
Do you see the same symtoms from twacker32?
