Object Pascal is a high
Object Pascal 是一种高级编译语言,具有强类型(对数据类型的检查非常严格)特性,支持结构化
和面向对象编程。它的优点包括代码的易读性、快速编译,以及支持多个单元文件从而实现模块化编程。
Object Pascal 具有一些特性以支持Borland 组件框架和RAD(快速应用程序开发)环境。在很大程
度上,本语言参考的说明和示例假定你使用Borland 公司的开发工具,如Delphi 和Kylix。
绝大多数使用Borland 开发工具的开发者是在IDE(集成开发环境)环境下编写代码并进行编译。
Borland 开发工具帮助我们设置工程和源文件的许多细节,比如维护单元的依赖信息。并且,使用这些工
具在程序的组织上还有一些限制,严格说来,这不是Object Pascal 语言规范的一部分。比如,Borland
开发工具遵循某些文件和程序的命名约定,若你在IDE 以外编写代码并使用命令行来编译,你可以避开
这些限制。
这些帮助主题假设你在IDE 环境下工作,并且使用VCL(可视化组件库)和/或 CLX(跨平台组件
库)创建应用程序。但有时候,Borland 一些特定的规则和Object Pascal 的通用规则并不相同。-Object Pascal is a high-level language compiler, strong type (of the types of data very strict inspection) features, structured and object-oriented programming. Its advantages include code readability, fast compiler, and documentation to support a number of modules to achieve modular programming. Object Pascal has some characteristics of components in support of Borland framework and RAD (Rapid should development of procedures) environment. To a large ex

ADOM+设计篇意在测试com+的事务处理能否正确执行。
将组件安装后,在组件服务中该com+组件的属性设置中将“激活”页的“启用对象池”选项选中,执行客户端程序调用上面这个方法,发现com+的事务机制不能正确执行,数据会写入数据库中。如果不选中“启用对象池”,则一切正常,数据并不会写到数据库中。
说明:Translation DataModule的设置,事务属性:requires a transaction,允许object pooling,pooled设为true,无论将AutoComplete设为True或False都会出现上述情况。
该问题最先由ytwxw (wxw) 提出,至今尚未有结论,我也发现类似问题。我俩探讨后无法解决,特在此再开一贴。请各路com+高手帮忙解答!
