I have a C# (VS 2005) program using a Twain dll of Atalasoft, to connect to a scanner.
When a fast scanner saves the files to disk, I show them in a PictureBox on the screen.
This goes all well while nothing else happens. When I click on a button of the window, or when an other window gets the focus, my program doesn's show the pictures anymore, although the communication with the scanner works fine.
I allready used the Refresh() to display the pictures, but that doesn't help.
Is there anyone who can halp me?
