I realize the compiler is old but I'm working on an assignment in an
education institution so I don't have a choice regarding what I use. I may
have misled you into believing that I am quite knowledgeable regarding Win32
programs...I am just a begginer programmer though and most of your comments
are above my knowledge level.

I included "basetsd.h" into the winreg.h and that cleared up the problem
with the type name expected as DWORD_PTR is declared in "basetsd.h" just
like you said. I'm a little unclear regarding the HKEY though as the error
is
Error:  winreg.h(146,12):'HKEY' cannot start a parameter declaration
so is that a problem with the definition of HKEY or the macro IN before it?
Am I missing a path to a lib file that has the full definition of the afore
mentioned usage of HKEY? I tried including winnt.h as well but with no
results should I redefine HKEY and all of it's included macro's or is there
a simpler solution?

if it would be easier to figure out what I'm doing I can send all of the
source files in a zipped packege.
thanks in advance
