A TWAIN Source must be selected to acquire an image.  The Source is analogous to the actual device that will ultimately acquire the image.  A TWAIN Source is denoted by the DTWAIN_SOURCE data type.  The Source can be selected either by the user using the TWAIN Select Source dialog box, or programmatically.
