Added SelectSourceByName(), GetAcquiredImage(), SetTwainMode()
GetAcquiredImage() returns a hDIB, there is a procedure here in the forum which shows how to get the image from that handle.
I don't know why AcquireToClipboard() is not working.
The help file is very complete.

Please try to use PrototypeC for the AcquireToClipboard function.

Code: Select all
DTWAIN::AcquireToClipboard(Source, DTWAIN::#DTWAIN_PT_DEFAULT, 1, DTWAIN::#DTWAIN_USENATIVE, #True, #True, #True, @Status)

Pb v5.60 LTS X86
After your question i have try with X64
But this time, PB is locked, and nothing happening
It's an old Canoscan 4200F, i love it, simple, faster, and i have bought several of this, for always use this model
