Hi,
I am using the standard twain calling functions from twain.org and
everything works correctly. The error happens when I try to press the
cancel button on the scanner to cancel the print job. My program
crashes and the error points to wiadss.dll. The problem will only
occurs when I try to scan using WIA. For normal Twain interface, the
cancelling works fine. The part of the code that crash is at
DG_IMAGE,DAT_IM AGENATIVEXFER,M SG_GET.
Anyone encounted this problem before?

Hello all,
I'm looking for a method, to program TWAIN directly via API calls...
Because the Twain OCX under Windows from Kodak is very slow...
When I scan via software or the OCX, the TWAIN driver reloads everytime,
I would like to keep it open, so I can close it when I exit the program.
Thanx,
Paul

Hello,
Has anyone had any success with python twain? I've downloaded
it and run the module however, I'm getting a python core crash when
calling to SourceManager.OpenSource. Needless to say, I've already
tested the scanner with a twain based application and it didn't crash it
so I'm guessing that the issue is with the python twain and not the
scanner itself.
Any tips, helps or <didn't you check that you wally comments> would

Hi all!
Sorry for this rather lengthy post. It's a long preamble followed by a few
questions based on that.
Here's my situation: I am trying to write a specialized scanner utility for
my own needs, and I want to use the module twain to control my scanner. I
haven't used the twain module before, which is most certainly why I'm facing
problems. My problem is to interprete some of the information I get from the
scanner. The scanner, by...

I'm currently developing an API of Twain for Java. As Twain is
implemented in C (and in fact Im writing and calling C methods from the
app) I couldn't find a better group to search for twain development
related issues.
Here's my question:
Does anyone know why when I negociate the capabilities ICAP_XRESOLUTION
and ICAP_YRESOLUTION I'm getting all sorts of repeated random values
like:
100, 100, 0, 0, 117, 5, 8, 0, 87, 78, 79, 83, 115,...

I'm hoping there is a TWAIN expert lurking here somewhere :)
I'm writing a very customized application. The software will be set up
in multiple location and will always have two types of scanners attached
to the computer. The scanners are microfilm/fiche and a flatbed.
So I've created a scanner setup screen where the user can select the
twain source for the fiche/film scanner and the twain source for the
flatbed scanner. I'm using an...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
