VB在水利水电工程造价软件开发中的应用

Application of VB in the development of project cost estimate of hydro-engineering software

通过对水利水电工程造价系统功能需求的分析和对定额库结构的剖析与设计,应用VisualBasic6.0(VB)编程的ADO技术,实现对定额数据库的操作,应用VB的类抽象定额的实体对象,简化水利水电工程造价计算。该系统采用VB的数据环境及数据报表制作成果的输出报表,应用VB的ActiveX(TM)技术实现对Excel、Word的使用。

This paper analyzes the function requirements of hydro-engineering cost estimate system and designs the structure of quota database, and then uses the ADO technology of VB programming to realize the operation of quota database. This paper mainly introduced how to realize function of database module by use of ADO technology of VB, and how to abstract quota object by use of class technology of VB to compute cost of hydro-engineering, and how to make output report by use of Data Environment as well as Data Report in VB, and how to use Excel and Word by means of ActiveX(TM, technology.
