I'm evaluating the software and now i came to a problem.
Before every scanning I will set a lot of capabilities (also custom capabilities).

Now I try to set a frame capability but don't know how to do that.

I think there is only the way to set a capability with TwainSetCapCurrentNumeric (or TwainSetCapCurrentString for strings) but how to set a Frame?

Thanks for every reply

You can do that using: TwainSetCapCurrentNumeric(ByVal Cap As TwainCapabilities, ByVal ItemType As TwainItemTypes, ByVal NewValue As Double)
use ICAP_FRAMES for Cap
use TWTY_FRAME for ItemType

I hope this helps,
