VB DLL - Dynamic Link Libraries and VB6 API

In our last (VB - Database Access Management), we saw how using the data control and bound data tools allowed us to develop a simple database management system. Most of the work done by that DBMS, though, was done by the underlying Jet database engine, not Visual Basic. In this lesson, we learn how to interact with another underlying set of code by programming the Windows applications interface (API) using dynamic link libraries (DLL).
