Good day.
I am using ImageEn 3.1.2.
How do you properly refresh the IO.TwainParams Source list after switching a scanner on or off to reflect the newly added or removed device without having to recreate the ImageEnView control?
There was another post that said to call SetDefaultParams but it only works when you switch the scanner on and not when you switch it off. If you switch it off it will stay in the source list.
Thank you for any suggestions. |
