I added Christof Lange's STRUCT.VCX class to my project, in order to get the printer number, when I compiled it, I got an error:

Visual Class Library c:\myproj\struct.vcx has the following errors:
Unknown FLL_MEMTOSTRING - Undefined
Unknown FLL_STRINGTOMEM - Undefined
Unknown FLL_LONGTOCHAR - Undefined
Unknown FLL_CHARTOLONG - Undefined

what should I do?

thanks in advance

regards,

Jerry
