Hi,
I am a developer working on giving support for scanners in our application.
Initially, we need to Open the source by calling DSM_Entry with message set to ‘MSG_OPENDS’. If the source is not connected to the system, then the scanner throws an error message. In my application, I want to suppress that error message and show my own custom message to the user instead. But, I am not able to find any way to get around it.
Any ideas?
MarkMUnfortunately that behavior is outside of the scope of the TWAIN Working Group. I agree that a TWAIN driver should not be showing a dialog to the user during MSG_OPENDS. However, you’ll have to contact the manufacturer of that specific scanner to see if they have a workaround.
SankalpThanks Mark! However, I do believe that there should be a chain of command from Application to Twain to Scanner for such messages.
RajatI have a similar requirement. I do want TWAIN driver message to be popped up. Can you please help out on this
RajatIts a EPSON FF 640 scanner.
