ویژوال بیسیک ۶ پیشرفته: تکنیک‌های قدرتمند برای برنامه‌های روزمره (سری توسعه‌دهنده؛ جلد فقط)

In Advanced Visual Basic 6, leading Visual Basic expert Matthew Curland demonstrates powerhouse techniques programmers can use to write high-performance, robust, and reusable VB code. Readers learn how to leverage the close relationships between VB, COM, and OLE Automation, extending the envelope of VB's capabilities and building high-quality, object-based systems. Key topics include how to:\* Control VB array variables explicitly to directly access arbitrary memory locations\* Call pointers to standard, cdecl, and class module functions\* Aggregate complete interface implementations into any VB object\* Override functions on any interface, including those implemented automatically by VB\* Turn any user-defined type into a lightweight COM object\* Minimize memory usage in systems with a large number of objects\* Safely create and manage threads in ActiveX EXEs and DLLs\* Interact with messages to customize windowed and windowless UserControl objects.The Web site accompanying this book contains extensive source code samples to enable all techniques without external DLLs. It also provides integrated type library add-ins for creating and editing referenced libraries, modifying binary compatibility files, and customizing the type libraries that VB generated for ActiveX components. With this compendium of best practices, sophisticated techniques, and valuable utilities, VB programmers will gain a deeper understanding of VB's inner workings and be able to extend its object-oriented capabilities.

Works in this series are designed to be the practical and informative sources developers need on the methods and tools for applying object-oriented technologies to real-world, large-scale applications.We will be starting with the four books following in the catalogue, and publishing more in the near future. We will be supporting the books with space advertising, author appearances at major conferences, co-marketing with DevelopMentor, and a major publicity push.-- VB from a COM data type approach: building more robust object-based systems.-- Partitioning, maximizing reuse, reducing memory requirements, creating lightweight objects, and more.-- By two of the world's top VB developers -- including Matt Curland, a long-time member of Microsoft's VB development team!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 managementtechniques that allow the creation of complex systems with many objects and minimal overhead. The book also covers threading, type libraries, component versioning, and more. The accompanying CD-ROM contains extensive source code, plus powerful utilities for advanced VB development.
