Xailer & OZ Software

Gday xailer,
I am getting the following error compiling old code.
Error: Unresolved external '_HB_FUN_FINDWINDOW' referenced from
X:PROJECTSCAPSYNC2OBJCAPSYNC.OBJ
and
Error: Unresolved external '_HB_FUN_DIALOG' referenced from
X:PROJECTSCAPSYNC2OBJCAPPROGRESSX.OBJ
How can I fix this?
Regards,
Leigh.

Sorry, I didn't seem to be getting thru, so I sent again and again. Please
disregard multiples.
Kind Regards,
Leigh.
