用dephi编程语言实现运筹学中线型规划运输问题－西北角法

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

此系统可以管理企业员工的出勤情况包括加班,签到,下班,迟到,早退,请假,每月休息天数,每天工作时间设定,添加删除员工和修改员工信息,并且每月会有月统计汇总功能.普通员工只能操作上班下班功能,其他管理功能由管理员也就是经理来操作.因为考虑到有的机器可能没有安装SQL Server所以我将系统分为两个版本分别是SQL Server版和Access版. 系统数据库内置20个登陆帐号和密码分别为: ID:001 密码:001……ID:020 密码:020.当系统启动时自动监测数据库连接,若没有提示错误则表示连接正常即可使用. 若发现使用Bug或功能上有不顺心的地方请联系我的邮箱(MSN): Lingo.wxy@hotmail.com 系统需要.Net Framework2.0运行时支持,下载地址：http://p2s.newhua.com/down/dotnetfx_38669.exe
