AddressOf

Most of the time you will not need to obtain any low level information about your variables.
However there are a few Windows API functions that require the memory address of a variable.

When you want to use API functions the following functions will prove useful:
VarPtr - returns the address of a variable
VarPtrArray - returns the address of an array
VarPtrStringArray - returns the address of an array string
StrPtr - returns the address of the UNICODE string buffer
ObjPtr - returns the pointer to the interface referenced by an object variable
