Would appreciate that if you could tell what does each of the enum in 'TwainItemTypes' mean.
When I run the code below, it returns me the TWTY_BOOL''.
Dim type As TwainItemTypes = oGdPictureImaging.TwainGetCapItemType(TwainCapabilities.CAP_UICONTROLLABLE)
You can read more in TWAIN Specification, see the section ItemType for Capability Container structures. In short, TwainItemTypes enum defines the item type used by a specific TWAIN capability. So in your example for CAP_UICONTROLLABLE it means this capability is boolean (TWTY_BOOL).
