Need An Equivalent To Dword Ptr

I need an equivalent to dword_ptr.A dword_ptr is 32 bits long when it's compiled on a 32 bit system and 64 bits long when compiled on a 64 bit system (more on this later). Odldy enough, a dword_ptr is not a pointer rather its data. I could use the vb "object" data type except that's supposed to be a slow method.I also don't know enough about the dword_ptr to know if it is strictly set at compile time or if it is estalished at runtime.The definition from ms for a Dword_Ptr is:"Unsigned long type for pointer precision. Use when casting a pointer to a long type to perform pointer arithmetic. (Also commonly used for general 32-bit parameters that have been extended to 64 bits in 64-bit Windows. )
