Programming Visual Basic 6.0 Applications - Level 2 Course

This course introduces you to objects, then explores the Microsoft data access technologies ActiveX Data Objects (ADO) and OLE DB. You will build reports using the Data Report Designer, use form modules, work with user-defined collections and create your own objects. This course will introduce you to advanced concepts, allowing you to create your own MDI applications, use Windows common controls, harness the power of the Windows API, and finish projects with optimization techniques and other professional touches.
