TwainOpenDefaultSource returns 0

What does it mean when TwainOpenDefaultSource returns zero. According to the documentation the value must be -1 or betweeen 1 and 7.

Hi,

The functions returns a Boolean. if the returned value is False you can use the Use TwainGetLastResultCode() and TwainGetLastConditionCode() functions for diagnosing the error.
