这是一个用ｐｂ编写的，通过ｏｄｂｃ来连接数据源的-This is a pb with the preparation, odbc to connect data sources

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

采用VC6和SQLSERVER2000开发，使用USKIN美化界面。主要功能包括还借书，超期提醒，管理员和读者帐户管理等等。-Using VC6 and SQL Server 2000 development, the use of landscaping USKIN interface. Main features include also a library, overdue reminders, administrators and readers account management and so on.

Excel表格是输入输出经常需要涉及到的。操作Excel表格的方式也多种多样。比如，通过调用Excel程序的COM组件对Excel进行操作。但是，这种方式限制较多，且实现难度比较大。但是，用于访问数据库的组件ADO，是支持多种数据源的，其中就包括Excel文件。我们可以通过ADO组件对Excel文件进行读写访问。当然，在.NET平台上对应ADO数据访问组件的是ADO.NET组件。我编写的这个类就是通过ADO.NET实现了Excel文件的读写。由于时间仓促，功能还不是很完善，会在以后有时间的时候进行版本升级。也请各位高手多多批评指正。-Excel spreadsheet input and output is often of the need to address. Operation Excel variety of ways. For example, by calling the Excel COM procedures for the operation of Excel. However, this approach is more limited and more difficult to achieve. However, for access to the database components ADO, is to support multiple data sources, including Excel file. We can ADO components to read and write Excel files visit. Of course,.NET platform counterparts ADO data access components of ADO.NET components. I prepared this category is achieved through ADO.NET read and write Excel files. Because time is so short, the function is still not perfect, will in future have the time for version upgrades. Members also criticized many exp
