Newbie Question

Hi
I am very new to scanning software, so my question may seem really dumb, but...
When I call vsTwain1.Acquire() the scanning software installed on my computer runs to control the scanner. Fine, but what would happen if I didn't have any scanning software installed?
Thanks

Hello,

You can check the following properties to make sure that you have TWAIN devices:
  • IsTwainAvailable - determines if TWAIN is installed in the system.
  • SourcesCount - returns the number of TWAIN Data Sources.
Please read the documentation to get more info.

Best regards, Alexander

I don't think I explained myself very well. I don't mean that the user doesn't have a scanner and it's device driver installed. When you start to acquire an image, on my computer a Hewlett Packard program runs automatically which lets me previes the scan, start the scan, change various settings etc. What would happen if I didn't have THAT software installed?

Our library works with TWAIN drivers. "Software" - it's a TWAIN driver. You will not be able to work with the scanner if TWAIN driver of the scanner is not installed in the system. :)
