Comments

DTWAIN_SetDefaultSource sets the TWAIN default source to an open Twain Source denoted by Source. After calling this function, any TWAIN-compliant application will assume that Source is the default source.

Note that changing the default Source using DTWAIN_SetDefaultSource also changes the WIN.INI values for the [TWAIN] section and DEFAULT_SOURCE settings. DTWAIN_SetDefaultSource places the proper values for these WIN.INI settings for the specified Source.
