Vxi Bus Test Software Platform - Design And Realization Of The Call The Activex Controls

The Master dissertation was written with the VXI_BUS Test Software Platform ----the Perfection Based On Windows and the task I had accomplished.VXI_BUS is known as a perfect platform of Instrument Bus System and Automatic Test System (ATS) in 21 century. It can be applied to the need of the armament test system. VXI_BUS consists of software and hardware part. The VXI_BUS test software platform is part of software content. It provides the computer's great abilities of computing and displaying. VXI_BUS test software platform provides a visual programming environment for ATS. Its aim is that it can provide a visual programming environment for users who can build ATS conveniently through the software without knowing advanced programming language.The thesis discusses the realization of COM technology in the VXI_BUS test software platform. Its one role is to build ActiveX container, which loads the common ActiveX controls, publishes the control's attribute and method, gets interfaces and creates ActiveX Control. The other role is to exchange the data between ActiveX object and VXI_BUS, invoke ActiveX object. It does these all by the help of VXI system that acts as a client. The content as following:Chapter one introduces the development and actuality of ATS and technology of VXI_BUS test software platform.Chapter two firstly introduces COM technology and ActiveX control, and then, discusses the significance and need for the realization of COM technology in the VXI_BUS test software platform.Chapter three discusses the realization of adding ActiveX control window to the VXI_BUS test software platform.Chapter four discusses the process of gaining COM interface.Chapter five discusses the design and realization of the ActiveX control's method window, and then discusses the design and technology of invoking ActiveX Control. It includes automation and exchange data.Chapter six makes some examples for testing invoking ActiveX control in the VXI_BUS test software platform.Chapter seven sums up the dissertation.
