API declaration: 64 vs 32 bits

This tutorial explains in details the difference between 32- and 64-bit architectures, when it comes to memory management. The PtrSafe and LongPtr keywords are discussed, to explain when, where and why they are used. A generic code skeleton is proposed, which can be embedded in any VBA application (not only Access), to safely deal with any architecture and VBA version. Finally, a full working example is built (how to force a listbox scrolling using API).
