Forum 'VintaSoft Twain .NET SDK Discussions'

I'm working on a WPF app with the latest Twain SDK.
Scanning works great - saving to multi-page pdf.

When I use a Canon DR-2580C scanner, after the last page has been scanned, the user interface stays up, even though there are no more pages to scan. If I use a different scanner (HP Officejet) when the scan is complete, the UI automatically goes away. In both cases, the Scan Completed callback gets called. I have to manually click the Cancel button in the UI, or click the close box to close it.

Is there a way in the scan completed callback, I can force the User Interface to close?

That fixed it - thank you
