访问对象

Difficult point of system this one of to store get data base in the form of binary scale " signature picture " of user, The second is to " signs " the binary scale picture in the report form from the data base, all these are which have utilized PowerBuilder to the access ability with strong data base.

本系统的难点之一是把用户的"签名图片"以二进制大对象的形式储存到数据库中，之二是从数据库中把二进制图片"签"到报表中，这些都利用了PowerBuilder的对数据库强大的访问能力，而得以实现的。

The BOS server is present in the network and accessing every object you want to backup according to a defined schedule.

该bos服务器是目前在网络和访问每个对象您要备份的，根据确定的时间表。

IDirectFBSurface Interface to a surface object, being a graphics context for rendering and state control, buffer operations, palette access and sub area translate'n'clip logic.

This is also the case if it is forced to use the equality comparison operator when the equality comparison operator is not available or not accessible for the specified function object type.

这也是如果它是被迫使用比较运算符的平等时，平等比较运算符不可用或不指定函数对象类型访问的情况。

Ble equality comparison operator defined.

Function，这是一个众所周知的事实，即目前没有合理的方法来区分是否对象具有特定功能的访问平等比较运算符定义。

If you don't need the complete documents but only one field you could also use the FieldCache class to cache that one field and have fast access to it.

如果你不需要完整的文档对象，你只需要其中的一个很小的字段，你可以使用 FieldCache类来缓存它，从而达到快速访问的效果。

With the development of network, database and Object-Orientation technology, Call Center System can meet the requirement of more customers accessing.

随着网络技术、数据库技术和面向对象技术的发展，呼叫中心系统能够满足更多用户访问的需要。呼叫中心系统的建立拉近了企业与客户的距离，为企业带来了大量的利润。

Simple Object Access Protocol is characterized with extensibility, flexibility and descriptiveness; however, these characteristics are maintained at its performance.

简单对象访问协议具有可扩展性、灵活性及可描述性的特点，但是具备这些特点都是以牺牲性能为代价的。

On this basis a design scheme of the database for SCADA based on the component object model is presented, in which the content and background of IEC 61970 standard is introduced first, then some different component model are assayed , then a design scheme of the database for SCADA based on the component object model is presented, the foreground application of SCADA is connected with the database by components.The new model have some advantages: system have disrelation with develop language ,the peculiarity of COM make the system fit in with different apply program developed with different language;(2) the system can be modified and upgraded easily by means of upgrading the component modules;(3) the system can be enlarged easily by means of adding the new component modules without quiet amendment in old system.

为此，本文介绍了一种基于组件对象模型的SCADA数据库系统设计方案，文中首先介绍了IEC61970标准的内容及产生背景，分析了几种不同的组件模型，在此基础上，提出了一种基于COM组件技术的SCADA数据库设计及访问模式，在此模式下根据SCADA数据库不同的功用划分了不同的组件模块，利用组件连接数据库与SCADA前台应用，基于组件技术的SCADA数据库设计有以下一些特点：(1)与语言无关性，COM的特性决定了此系统上可以应用不同语言开发的应用程序；(2)系统易修改及维护，用户可以通过更新组件模块的方式修改及维护系统；(3)系统易扩展新的功能，用户可以通过开发新的组件方式将新的应用与原系统结合，而不用对原系统做很大的修改。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
