在VB中调用动态连接库

作为一种简单易用的Windows开发环境，Visual Basic从一推出就受到了广大编程人员的欢迎。它使 程序员不必再直接面对纷繁复杂的Windows消息，而可以将精力主要集中在程序功能的实现上，大大提高了编程效率。但凡事有利必有弊。VB中高度的封装和模块化减轻了编程者的负担，同时也使开发人员失去了许多访问低层API函数和直接与Windows交互的机会。因此，相比而言，VB应用程序的执行效率和功能比C/C++或Delphi生成的程序要差。为了解决这个问题，在一个大型的VB开发应用中，直接调用Windows API函数几乎是不可避免的；同时，还有可能需 要程序员自己用C/C++等开发一些动态连接库，用于在VB中调用。本文主要讨论在32位开发环 境Visual Basic 5.0中直接调用Windows 95 API函数或用户生成的32位动态连接库的方法 与规则。-in VB called dynamic link library as a simple, easy-to-use Windows development environment. Visual Basic from a launch on by the broad welcome to the program. It enables programmers no longer has to directly face the complex Windows news and the energy can be focused on achieving the function procedures, greatly increasing the efficiency of programming. But everything Weilibiweibi. VB highly modular packaging and lightened the burden of programming, also enable developers lost many visit the lower API function and direct interaction with the Windows opportunity. Therefore, comparison, VB application program efficiency and function than the C / C or Delphi generated procedures to be poor. To solve this problem, in a large VB application, directly call Windows API function is almost inevitab
