My application has scanned fine with a Xerox 152 on XP. I recently tried it on Win 7 + 64 bit and it crashed during a scan. The app is targeted for x86. I am also having reports of it crashing on 32 bit Vista using the same Xerox 152 scanner.

I am using the latest TWAIN drivers for the scanner. Here is the TWAIN log from the Win 7+64 Bit. I am working on getting a copy of the TWAIN log for Vista+32 bit.

Additional pieces of information:

* I just updated my GDPicture.NET to 6.5.0.2 (the latest I believe), and the problem persists
* The same crash happens in your twain scanning sample if I uncheck HIDE UI. I have no idea if this is related, but it happens. If the HIDE UI is checked, it scans.
* I've tried supplying a valid window handle to the TwainOpenDefaultSource and TwainAcquireToGdPictureImage but it made no difference

Also - here is the stack trace, and the crash is definitely happing in TwainAcquireToGdPictureImage

Hi Andy,

Thank you for the clear report. Unfortunately I can't see any problem in GdPicture. I suspect a problem into to TWAIN driver.
The log ends at "Start: NativeXferHandler.", this mean the next step is 100% accomplished by your TWAIN driver.

I can give you 2 suggestions:

- Try to find another Driver for your scanner
- Try to use the latest TWAIN DSM provided by twain.org. You can download it from http://sourceforge.net/projects/twain-dsm/files/

With best regards,

Loïc

Hi Loic,

I updated my hardware specific TWAIN driver (I thought I was running the latest), and it fixed the problem on my Win 7 (64 bit). I'm waiting for a report back on Vista (32 bit).

I'll let you know when I know.

Happy Holidays!
Andy

Hello,

I'm encountering an issue when trying to connect my application winform (.net) using gdpicture.net to a scanner futjisu 6670 on a Windows 7 64bit .
I get the twainlog.txt telling that :

I haven't met this issue when i installed my application on a win xp 32bit.

Can you help me resolve this issue, because i checked many solutions but in vain.

thank for any helpfull and prompt reply.

Hi,

Please follow the steps here: viewtopic.php?t=1486

If, that doe snot work, unfortunately, most scanners do not have correctly implemented 64 bit drivers. This is beyond the control of GdPicture. For Twain, it is always better to stick with 32 bit because those are usually the correctly implemented drivers.

Best,
Sami

Thanks Sami for your reply,

Hope it will resolve the issue.
