I am new to the LEAD tool TWAIN ActiveX controls, and not all too familiar with TWAIN nor scanning in general.  I am trying to support this code that calls the SelectSource(), which returns a short int.  Is there a code for if the user clicks Cancel in the Select Source dialog?  From your help file, it only says 0 means successful, but it does not show the list of error code values (when I click on the link, the link was broken, and I cannot view the list of error codes).  Right now, there is no way for me to know if the user clicked Cancel vs. if there is truly an error.

I am using VC++ on Windows XP.

Thank you,

When you click Cancel the method will return 20563, which means "Cancel Operation Done".
