vbaObjAddref

Calls IUnknown::AddRef on the COM object at a given address.

Syntax: vbaObjAddref Address

Address

required LongPtr. The address of an IUnknown-derived COM object — typically the value returned by ObjPtr.

The reference count of the object is incremented by one. The runtime does not validate that Address points at a real COM object; an invalid pointer will crash the host.

This is a low-level primitive. Ordinary code does not need it — assigning to an Object variable already addrefs.
