>Can a .pdf file be stored in the memo field of a foxpro table?

Yes you can "store" it in the memo field. Like:
insert into (table_name) (memofield) values (filetostr("c:\acrobat3\reader\acrobat.pdf"))
or just a file name:
insert into (table_name) (memofield) values ("c:\acrobat3\reader\acrobat.pdf")
