Good to hear that the problem has been solved. 🙂
Which OS are you using? If you are using Windows 2008/Vista/7, please try right-clicking Twack and choose “Run as administrator” and see if you get the same problem. If you get the same problem, please try re-installing the driver for your scanner.
And if I put my data source extension from “.Ds” to “.Dll” why app is not recognized?
I guess you’ve already named the extension back to .ds as suggested by Kaij. Please double check.
It would be helpful if you could provide more information about “cannot find the data source”.
1. After you install the scanner driver, have you tried to use Twack? And is Twack able to find the driver?
2. If the answer for Question 1 is No, please first check whether the driver is fully TWAIN compatible (you can check out the documentation or ask the vendor to get the details). If it is TWAIN compatible, please also check whether you have the permission to access the source. You can try to run the app as administrator to verify that.
3. If the answer for Question 1 is positive, you need to check out your app and it’s TWAIN compatibility.
Have you ever tried Twack to scan images from your scanner? Did you get the same problem?March 7, 2013 at 5:37 am in reply to: Problem with TwainTransferMechanism.Memory and auto detectio #25827
Does your computer has sufficient memory to hold the scanned images? If this is not the case, it would be helpful to paste your source code here.
With TwainTransferMechanism.native or if I scan a page with settings A4 landscape and TwainTransferMechanism.Memory, I don’t have problem
When you try these two options, did you change the other properties, such as the resolution?
In addition, did you have the same problem with Twack?
If you just want to test the TWAIN scanning on Mac, you can try our TWAIN scanning online demo page:
On this demo, you can set scan settings, perform scan, edit image and save/upload image with all browsers on Mac. Furthermore, the demo is developed with Dynamic Web TWAIN, which is compatible with TWAIN specification 2.1 and supports all browsers on Windows and Mac OS.
Note: a small browser plugin will be installed.
You can try the online demo and let me know if you have any question.
