How to get MSG_XFERREADY in canon canoscan lide 110?

[gopikanna]

hi,
I am working in Twain application.It is TWAIN 2.0 Complaint.

I am using twain 2.3 version dll,to communicate with Canon canoscan lide 110(scanner) in windows 7 machine.

But i could not get MSG_XFERREADY message either through MSG_PROCESSEVENT or MSG_REGISTER_CALLBACK.

i don’t know how to get the MSG_XFERREADY from canon but i could get this message from others scanners like Kodak i1120 ,fujitsu fi-5120c and HP scanjet G4010.
Please someone help me to solve this issue.

Thanks

I solved problem, downloaded example and source from http://netcode.ru/cpp/?artID=5173.

There are exception while scanning too, but application have final call with handle to bitmap and no crashes occurs.
