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.

今天突然找出以前的一小段代码,是对MFC中CDatabase类的一点小改造。CDatabase类中的ExecuteSQL函数可以用于直接执行SQL语句,但是在执行Update,Insert,Delete语句时无法得到影响的行数,新的CDatabaseEx类就实现了这个功能。 -before suddenly find a small section of code, the MFC CDatabase kind of a little transformation. CDatabase category of ExecuteSQL function can be used for direct execution of SQL statements, but the implementation Update, Insert, Delete statement could not be affected when the number of rows, the new CDatabaseEx category on the realization of this function.
