PI数据库标签查询、快照查询、历史数据查询 时间格式转换(pi demo)

用VC++下用ADO两节Access数据库，实现对Access的操作(With VC++ next two Access database with ADO, to achieve the operation of Access)

ODBC连接数据库,可以实现查询,插入,删除操作.(vc++ implement odbc access database)

使用ODBC访问数据库，一则ODBC是直接封装在MFC库里面的，二则忙着考研没有时间学习dao。 ODBC和DAO用起来可能最大的区别就是ODBC使用之前得先建立数据源，根据不同的数据库，使用的参数也不同。具体请看在这之前的一片文章。里面有许多东西没有说，属于高级技巧性东西，得学你们自己摸索。(Using ODBC to access the database, an ODBC database directly encapsulated in the MFC inside, two busy Kaoyan no time to learn dao. ODBC and DAO can be at the biggest difference is that must be built before using ODBC data source, depending on the database, the parameters used are also different. Details, please read an article before this. There are many things not said, things are high skill, have to learn your own. )

MFC架构下，通过ADO方式连接Access数据库的实例，事先了完整的添加、修改、删除功能，VS2010编写。特点是实现了数据库中日期数据类型的读写，比较有借鉴意义。(MFC framework, connected through the Access database, ADO instance, in advance of the complete add, modify, delete function, VS2010 preparation. Feature is realized in the database to read and write the date data type, compared with reference.)

读写Excel 用Ado对Excel可以很方便的进行读写 (read and write Excel Ado right with Excel can read and write to facilitate the conduct of)

本人自己编写的VC++访问数据库程序，包含了ADO、ODBC等方法，可访问MSSQL、SQL、ACCESS等数据库。(I have written VC++ Access database program, including the ADO, ODBC and other methods to access MSSQL, SQL, ACCESS and other databases.)

说明：  Visual C++中ADO程序员的参考指南文件，包括ADO入门和高级进阶部分，另外还有ADOX等相关内容(ADO in Visual C++ programmer' s reference guide documents, including entry-level and high-level advanced part of the ADO, in addition to other related content such as ADOX, ADO MD .)

MFC编程，VC连接ACCESS数据库，实现对数据的增、删、改、查等操作(VC connection ACCESS database to achieve the data add, delete, change, and other operations)
