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

Dynamic TWAIN is very powerful and easy to use.
It is compatible with TWAIN specification V1.9. and has built-in JPEG
encoder and decoder. It supports all three image transfer modes and many
other features and you can typically do your TWAIN job in several lines
of code.

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...

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_IMAGENATIVEXFER,MSG_GET.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
