In Advanced Visual Basic 6, two of the world's leading VB experts take experienced developers "under the hood" with VB, introducing powerful techniques for writing high-performance, reusable code that leverages the close relationships between VB, COM, and OLE Automation. This book presents advanced VB programming from a COM data type approach, helping developers build more robust, effective code -- and overcome obstacles that appear as they "push the envelope" with VB. Developers learn how VB describes arrays, and how to duplicate that definition manually to perform simple type casting, and gain unprecedented control over how their programs use memory. The authors introduce best practices for interface-based design using normal VB class modules; show how to partition code for optimal reuse; and more. Next, they present advanced techniques for creating COM lightweight objects; and alternate memory management techniques that allow the creation of complex systems with many objects and minimal overhead. The book also covers threading, type libraries, component versioning, and more.
Matthew Curland is a long-time member of Microsoft's Visual Studio
development team. Visual Basic's IntelliSense feature is his most
visible contribution. A frequent and popular speaker at VBITS, he
also contributes black-belt articles to the leading VB journal,
VBPJ, and is the co-author of Object Programming with Visual Basic
4 (Microsoft Press).
