Thank you very much for your reply. Now, I know how to obtain all the possible resolution values of my scanner from TW_ENUMERATION struct.
I also have got another doubt. Trying to do my application more general and wanting it works with a large amount of scanners, I´d like to know if there is a way or a mechanism to know in which type of capability structure (TW_RANGE, TW_ENNUMERATION…) one scanner returns me its capability values. If I know this information I will be able to know in which structure I should look for the values I want.
Thanks.
