The Delphi source code to an attempt to write a DLL for this has been available for quite a while now at:
http://www.sools.com/files/vdstwain.zip

Unfortunately I haven't been able to fix it so far, sometimes it causes exception errors for no known reason.

The error might be to blame to the twain driver I tried to use however; its author is infamous for creating buggy software. It does work if the twain component is compiled into a .EXE file however.

You can do with the code whatever you please, but please note that this may not apply for the included third-party MultiTWAIN component.

Best regards,

Tommy

Would it work better in VDS 5 after we now have the ability to compile
any type resource into our executable?

VDS 5 wouldn't change anything to this, except of course that it does make it not
work at all...
