SUPER NOTA: Estas funciones me la envió el colega Joe en la fecha indicada arriba, pero por un despiste (más grande de los que acostumbro a tener), se me olvidó publicarlo... lo siento, pero más vale tarde que nunca...

Billy-
Los puedo hacer las versiones MBF
si hace falta.
Cada semana alguien pide estos
functions, y VB32 no los tiene.

El código:

'
Option Explicit
' Old Basic routines, unsupported in Win/VB3/4/5
' uses RtlMoveMemory to replace hMemCpy-
' since hMemCpy is not exported in Win32.
