VB6 or VB.NET?

For VB.NET, to pass by reference, you'd have something like:

Sub Foo(ByRef a As Integer)
   ' ...
End Sub

Pointers you don't really have.

In VB6 (not sure about .NET) there are three undocumented functions

VarPtr:  Gives the memory address of a variable
StrPtr:   Gives the memory address of the contents of a string
ObjPtr:  Gives the memory address of the object
