I have found Transcenders to be invaluable when
preparing for certification exams. Right now, they have several demos available
including one for the VB6 Desktop Applications exam. Check it out at: ftp://ftp.transcender.com/ftp/vb-cert-desktop60_demo.exe
and look at other demos that they have at their website at: www.transcender.com . [And no, I do not
receive anything for recommending them]
