How I connected to pgsql using M$ visual basic

hi,
i searched the information i posting, but can't find it, even in this ml.
now that i know how to connect to my postgresql server using visualbasic, i
post this little sub
using access, it should be easier, because access has the object docmd which
has the method transferdatabase

i commented out the code which should delete the table (if exist). if it
does not exist, an error (err 3146) is raised: but it is too generic!
any suggestion?
bye
