I can get the pointer handle to lpType, but its just an integer, how do i actually get the data lpType is pointing to?

Answer 1

As it clearly tells says on MSDN it is just an integer... its just an enum from 0 to 7 where 0 is REG_NONE ... 7 is REG_MULTI_SZ. Check out here for more detail Look under key types.

Answer 2

'lpType' does not point to the actual data, the actual data is returned in the 'lpData' parameter.
