    Hi,

    I have to work with a TWAIN VRS driver (last version) shipped with the Fujitsu 6130 (but the problem seems to be more general).

    The behavior of the Fujitsu driver alone (ie not the VRS one) is ok, or at least I know it and I can handle it.
    But the VRS driver, is pretty unstable with my software (ie it crashes for unknown reason by itself after few pages).

    I tried it with the new twainapp MFC version for the TWAIN Group and I have the same behavior (compiled with VC++ 2005), ie a huge number of exceptions captured by the debugger ObjectTWAIN::CTWAINArrayException, something like that, until it accesses a null pointer or an invalid memory address somewhere unhandled.

    The previous twainack simply explodes on the ‘enable DS’. 😯

    Do you have troubles with VRS drivers and a way to solve this ? 😕

    I started by click on ‘1 Load/Open SM’, then, ‘2 Open Source’, and as soon as I release the left button, the application simply disappeared from the screen.

    Actually I started to run it through the DSM v2, and the DS (TWAIN VRS) still generates hundreds of exceptions and memory access violations, but it looks like it’s staying alive … so this will be my workaround for now …

    Why use VRS ? Skip the cost and do everthing in the application. Modern documentsscanners delivers jpeg compressed data so a straight forward USB connection is more than enough to drive even high-speed scanners at full speed. A good app uses the mulitcore in modern PCs to scan and process the documents at the same time

    VRS along with the adrenaline card cleans images to a level that a standalone program cannot achieve.

    I am currently writing a scanning app that uses the vrs functionality with twain.

    I havent ran into the issues described above. The only issue I have ran into is that with the vrs once the source is opened it must stay open. If the source is closed and then reopened in the same session, the vrs will crash.

    Did you install the vrs twain driver off the dvd?

    There is application(s) able to do cleaning as good as VRS and even more. Know of PixEdit which all kinds of stuff for optimizing scanned images. And it can do this on any scanner and even any file since this functionallity runs on an openend image wherever this comes from scanned, opened file, an MFP or whatever. Automatic determination of greyscale, BW, color page, filtering, deskew, blank page removal, PDF/A and a great feature called PDF/A Compact which makes really small files even when color on pages. Some kind of layering or dividing up the pages in areas. Unbeatable editing like WYSIWYG reordring og pages even between documents and a heck of a lot of other stuff. The ggod thing is also it can use any Twaindriver for all this, you do not need any special expensive stuff like VRS, dedicated hardware boards or anything since it scans in full speed from modern documents scanners using their built-in compression – only connect through standard USB. Has also full programing interface DDE and ActiveX.
