                             -----------------------

We were previously the principal accountants for ActiveCore  Technologies,  Inc.
(Formerly IVP Technology  Corporation)  through February 9, 2005. On February 9,
2005, our  appointment as principal  accountants  was  terminated.  We have read
ActiveCore Technologies,  Inc.'s statements included under Item 4.01 of its Form
8-K dated February 14, 2005,  and we agree with the statements  made in response
to that Item insofar as they relate to our Firm, except as follows:

1.    The report of  Weinberg  & Company,  P.A.  on the  consolidated  financial
      statements  of the Company for the years ended  December 31, 2003 and 2002
      contained a modification  expressing substantial doubt about the Company's
      ability to continue as a going concern.


                              Very truly yours,



                              WEINBERG & COMPANY, P.A.
                              Certified Public Accountants
