一个使用DAO的例子

使用ADO的数据复制原型 这是一个几乎在七年前我试图做的数据复制原型。它的一些部份可能仍然很有趣。最初，它使用了一个建造在ODBC上的的专有库，但是它可被容易地修改以使用任何的数据库接口层。 演示例子使用ADO和MSDEV 中自带 Nwind.mdb MS Access数据库。 这个原型引擎使用一个实际的或者人工制定的唯一的数据库内索引来标识一个记录。 在插入记录时可以正确处理Auto-Number或Counter数据类型。通过初始化复制条目集合或复制器类的Init方法中的链接描述符来执行复制计划。参考DemoCopyHelper.cpp这个例子. - Uses ADO data duplication prototype this nearly the data duplication prototype which I attempts in seven years ago to do.

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
