What error are you getting?  (See GetLastError().)

It may be related to PTSTR being a pointer-to-TCHAR (either Unicode or
ANSI character, depending on the setting of the UNICODE define when you
include the header file).  Is nameSize maybe supposed to be the number
of TCHARs in the array, instead of the number of bytes?

I don't know whether that's the issue (it would depend on what error
number GetLastError() returns), but it's my first guess.
