| With the continuous improvement of the level of equipment and the support of meter sensor technology,communications network technology and computer application technology,the modern logging-oriented technology has been increasingly shows its characteristics of modern information technology.The quality of logging-oriented system plays a vital role for scientific and accuracy of logging-oriented.Compared to the abroad,domestic logging-oriented system software are relatively backward from development model to function.The poor of General using and code reusability is one of the reasons for the slow development of domestic logging-oriented system software.The graphical library not only the core of logging-oriented system,but also the part of spending human and material resources most.How to develop a graphical library with reusability and being developed secondly,is important for improving the efficiency of system development,and for this paper,it is the point that will be solved.At Beginning,in this paper we discuss the present situation of logging-oriented system abroad and domestic,pointing the problems in domestic logging-oriented system;then,we analyzed the feasibility and related technologies of software reuse,and take the COM-based component development technology.Next,we introduced the characteristics of COM technology and automation technology as well as the ActiveX technology which based on COM technology;and then under the MFC framework provide by Microsoft,we introduce the specific achievement of functions of graphical edit and management components;Finally,this paper discuss the graphical library components used in Visual Basic,Java development environment,which prove that the use of graphical library has nothing to do with the development environmentd,and has a very important guiding significance to the reusability of logging-oriented system development. |
