Size of an object

Guys, its 1:52 AM here in India and I am awake for the Nth night. Don't laugh at me if I sound silly.

How do I get the size of my object? Like you can always do a Len(TypeInstance) to get the length of a structure. Like sizeof(Object) tells a C++ proggy his object size. I want the size of my object (no pun intended).


Dim a As Class1
Set a = New Class1
MsgBox Len(a)

Secondly, can I transfer my object to a byte array using CopyMemory without worrying about Unicode to ANSI conversions for the BSTRs?
