电子表格的输入和输出往往需要解决的问题。手术费。
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

这是个使用ADO类编写的IP地址来源地查询程序，给出IP地址可返回IP所属地区或国家，给出地区或国家的名称或部分名称可查询所有的IP地址。程序需要一个动网论坛的IP地址数据库（ACCESS格式），由于太大所以没传上来。-it is prepared to use ADO type of source IP address inquiry procedure, given IP address can be returned to the IP respective regions or countries, regions or countries are given the name or names of inquiries can be part of all the IP addresses. Procedures need a louder IP address database (ACCESS format), too-so much onto.
