Development And Research Of The Cost Software Of Hydraulic Engineering

At present, construction projects of hydraulic engineering have already generally adopted competitive bidding pattern, this requires build unit and construction enterprise to work out base price and quoted price accurately in time, no matter one works out by hand traditionally or uses Excel, it can't meet fast and accurate demand, so, development and research of the cost software of hydraulic engineering (CSHE) have important meanings. Meanwhile, defects of current software existing is very difficult to suit with cost workout during developing period of economic system reform, so developing CSHE with more perfect function, more strong practicability, more convenient operation and use is necessary.In this paper, Visual Basic 6.0 is used for front developing instrument, desk-top database system-Access is adopted as database platform of ground, ADO technology is used to visit and operate database, prevalent Oriented-Object method is adopted as design method of the procedure.On basis of analyzing workout method, quota structure is analyzed, method that characteristic table of quota and quota repertory describe the quota together is adopted to design compact quota database, output database is set up according to the norm of cost workout. Meanwhile, quota entity is abstracted on basis of quota database by fully utilizing object-oriented technology, to realize encapsulation of attribute and operation, classes and functions of generating all kinds of reports are compiled by means of VBinterface alternating with users is set up and procedure codes are compiled to realize engineering management and function of workout cost, codes are compiled by utilizing OLE technology to turn cost tables into Excel electronic tables, to generate workout explanation draft of Word form.The software that this project has developed can work out estimate, budgetary estimate , budget, base price, quoted price, produce beautiful and neat reports automatically, the reports can be edited according to the demand, thus cost organizers are extricated from a large amount of tedious and repetitive work. The software system has characteristics of operating simply, a good adaptability and commonness, the normative achievement.
