Hi!
As a VB .NET developer, I am going to acquire image from scanner and have it as an System.Drawing.Image in my program. As there are nothing about such task in the .NET Framework, I have to use an API. I have also read somethings about "Technology without an interesting name (TWAIN)" and "Windows image acquisition (WIA)".
How can I do that? Which API is proper?

I am much obliged to you for your assistance. Regards!

There are several image scanning components available from ISVs, some of which are listed here- http://www.windowsforms.net/ControlGallery/default.aspx?Category=27&tabindex=10

Choose a component that meets your development needs and let that drive your choice of APIs. WIA has a TWAIN pass-thru, so a long as your scanner is TWAIN compatible, you can use either one.
