PB开发者的重点说明，能够很好的介绍给初学者学习PB开发。(PB developers highlights can be a good introduction for beginners learning PB development.)

数据库访问层的通用设计。可根据配置文件的更改适应不同的底层数据库。隔离业务逻辑层。采用C++标准库及ADO方式对数据库进行访问。(The universal design of the database access layer.According to the configuration file changes to adapt to different underlying database. Isolate the business logic layer. C + + standard library and the ADO way to access the database.)

1.备份一个要修改的源文件,并放到新的工程目录中. 2.备份一个要修改的数据库,并改成新的库名. 3.删除工程文件和主窗口中的引用单元. 4.改主窗口中的窗体名称和主菜单名称等. 4.改数据库连接名称,并把配置文件清空. 5.运行程序,随便输入名称和密码点击登录. 6.关闭程序,打开配置文件,修改参数如下:(1. Back-up source of a document to be amended and new projects on the directory. 2. Backup a database to be amended and changed to the new library name. 3. To delete the project files and references in the main window unit. 4 . to the main window of the form name and the name of the main menu. 4. change the database connection name, and the empty configuration file. 5. run the program, simply enter a name and password click login. 6. Close the program and open the configuration file , modify the parameters as follows:)

数据库连接池的使用步骤,比较有用，如果忘记的朋友可以看看。本人自己写的。(Database connection pool using steps, more useful, if you forget the friends can see. I wrote it myself.)

一个读去Excel表，并将数据存入数据库的例子！可选择多种数据库！(an Excel table to read, and will maintain a database of examples! A choice of multiple databases!)

一个用于实现不同数据库数据同步的程序，用jbuider开发，在一个数据库数据修改后，通过触发器触发同步程序，同步程序通过socket与另一个数据库的同步程序通信，达到数据同步的目的(One for different database data synchronization process, using jbuider development, data modifications in a database after the synchronization process through the flip-flop trigger, synchronization procedure socket with another database synchronization process communication, to achieve the purpose of data synchronization)

EXcel 过滤器，数据库编程源码，很好的参考资料。(The EXcel filter, database programming source code, a good reference.)

复件 封装ADO之MFC应用，对于数据库操作非常有帮助(copy Packaging ADO's MFC application, database operation has been very helpful)

VB复杂计算，含绘图功能，同时也是个实用的空调辐射温度　舒适度衡量软件，稳定可靠(VB complex calculations, including graphics, is also a practical air-conditioned comfort of radiation temperature measuring software, stable and reliable)

使用MFC DAO访问数据库，并实现了收支数据的条形图绘制。(Use MFC DAO database access, and to achieve a balance of payments data to draw a bar chart.)
