Hi all

I am new in all this imaging business and i am developing an application that is suppossed to scan a page if the feeder is loaded, i use V,.14.5 LeadTools and an Inotech scanner

the Scenario: I have five papers i need to scan, i load the first one and press scan button, it scans and then waits for another paper to be loaded, then without pressing the button Scan again, it should scan the second paper..

i can currently scan by pressing the button. Please help!!!

You can detect whether or not your scanner has paper loaded into the feeder by using GetCapability with the capability CAP_FEEDERLOADED. For an example on how to get and set TWAIN capabilities, take a look at the documentation on GetCapability and SetCapability.

Hello,

You can end a TWAIN session by calling the TwainSession.Shutdown method.
When exactly do you get the DialogBox "Waiting for Scanner" with a stop button?

Thanks,
