摘　　要：动态链接库是一种特殊的可执行文件,它的内存机制可以减少系统资源占用,而且便于系统升级。介绍了D elph i中动态链接库的基本概念及其创建调用方法、步骤,并以一实例配合说明如何在D elph i中应用动态链接库,从而实现提高系统性能。由于DLL具有节省内存、共享代码、升级方便和独立于编程语言的优点,现已被广泛应用。另外,D elph i利用DLL实现了窗体的重用机制,用户可以将自己设计好的窗体储存在一个DLL中,在需要的时候可随时调用它。DLL（Dynamic lank Library） is a kind of special executable file,and its memory mechanism can reduce occupation of system resource and it is convenient in updating. In this paper,DLL＇s basic conception and the method of creating and calling DLL are presented. How to use the dynamic link library in delphi application is introduced by an example, so that DLL can increase system performance. DLL, with advantages of saving storage,code sharing,convenient updating and language - independent ,has been applied widely. In addition,Delphi realizes form repeat system by DLL. The user can store the form designed in the DLL, and call it as required.
