First, thanks for the answer.
Secondly, I tried to use the function you sent me, but I got false in this line:

Code: Select all

bool success = oGdPictureImaging.TwainOpenDefaultSource_2(0);
Do you know what could be the problem? What this function checks?

Many thanks.

Hello,

You should check the reference guide ;)

You can subsequent use these methods to diagnose the error:

- GetStat()
- TwainGetLastConditionCode()
- TwainGetLastResultCode()

Hope this helps !

Kind regards,

Loïc

Hello...

I am making a Silverlight application that necessities to speak with a scanner (utilizing TWAIN drivers)...., I know Silverlight can't do this straightforwardly.., and I should utilize Java to communicate with the scanner.
