用Delphi控制Excel的数据

此文章包含powerbuilder环境下编写相应驱动，对ep9315进行二此开发，使其和低速器件通信。具有较强的指导意义-This article contains the PowerBuilder environment to prepare the corresponding drive of the second ep9315 this development, so that it and low-speed communications devices. Has a strong guiding significance

众所周知，软件开发离不开对数据的访问。数据访问在整个软件开发的三层构架中属于数据层，是其它两层的基础。没有了它，存储的数据变的毫无意义。与此同时，数据访问的效率将直接影响到软件的质量。一个数据访问缓慢的系统是客户无法容忍的。一个好的系统必然有一个高效的数据访问方法。由此可见，数据访问在软件开发过程中是非常重要的。如果能统一对数据的访问方法，那么一切有关数据访问方面的问题都可以得到解决。我的系统将可以面向所有的数据源，甚至是未来将会出现的数据源。 预期结果 实现对SQLServer,ODBC,OLEDB数据源以及工业中的Citect，IFix监控软件数据源的统一访问。 开发环境： Microsoft Windows2000开发平台 开发工具： Microsoft Visual C++.NET 数据源： Microsoft SQLServer2000，Citect,Ifix，ODBC 文件说明： DAServer2.dll是一个统一数据访问平台。提供OLEDB标准接口。用户可对其进行访问。 SQLServerProvider.dll是针对SQLServer数据源的提供程序。 config.ini是系统配置文件。- Data access in the entire software development framework is a three-tier data layer, the other is a two-tier basis. Without it, the data storage change meaningless. Meanwhile, the efficiency of data access will directly affect the quality of the software. A slow data access system is the customer can not be tolerated. A good system will be an efficient data access methods. This shows that access to data in the software development process is very important. If reunification of data
