The key to solving this problem is to answer the question "How will I 
know what type of data that pointer points to?" Once you determine what 
is being pointed to you can cast Pointer^ to that type and all should work.

I would use Pointer as an untyped pointer to anything and ignore the 
warning. Perhaps you can turn off that warning for this code segment 
since you are doing this intentionally.
