Hello, I encountered a problem now, I do is to provide the data source in the twain program examples can be run, but in other software such as Photoshop which support Twain software by mistake, cannot run, why?And if I put my data source extension from “.Ds” to “.Dll” why app is not recognized?Thank you.~
The first problem seems to be solved, probably because of QWidget than QApplication the earliest, but second problems for solution.
Data Sources need to have the extension .DS.
There is no need to rename it to DLL and if you do that the DSM does not recognize it.
Best regards,
KaijI found there is a problem, I will DS to move to the new machine environment, scanner driver is installed, but can’t find my DS. Help!~Help!~Help!~
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.

1, is a useful Twack, Twack could not find the driver; 2 the driver should be compatible with Twain, because I am on my machine and in other visual studio2008 machine is capable of running DS, is not in the absence of the environment of the machine; the permissions are administrator privileges — —
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.

I use Windows XP and I did not change the extension “.Dll”, at first I thought would need to “.Ds”, instead of “.Dll” that good, I just know do not change, so I did not change the extension!~ —— ——

Found the problem, and should not be put in some DLL DS with Microsoft.VC90.CRT.manifest or Qt put together, is in the twain folder before a file, will now DS with a number of DLL and Microsoft.VC90.CRT.manifest and app together on the C drive Twain folder, can find my DS, but the antivirus software will actually false positive virus —— ——,To make a long story short, thank you! ~
Good to hear that the problem has been solved. 🙂
