The purpose of this study is to understand what is ActiveX control and how to utilize it in developing dynamic web pages. For this purpose, some literature survey and experimental practices with PC were done to understand the differences among web programming technologies such as visual basic, java, XML web services. In order to scrutinize the functions of ActiveX controls and the comparison of their technology with currently introduced XML web service, a study on the history of Internet programming with a focused view on ActiveX control was also performed. With the knowledge of the fore mentioned, Actual design and building experiments of web pages using ActiveX control pad were implemented. The results show that Microsoft ActiveX controls, formerly known as OLE controls or OCX controls, developed to compete with java applet in internet battle fields, turn out to be useful in software reusability, cost-saving and time-saving etc. However, the use of ActiveX controls has been confined in window platform, Overall, this study was useful for understanding the usage of ActiveX controls in web pages.

Microsoft's ActiveX corresponding to the advanced type of COM based distributed application model is made available for the use of component communication[1]. ActiveX supports reuse of code and object linking, so developers can integrate many objects into application and improve the efficiency of development. Also, Integration of seperated application makes easy to develop customized program[2]. ActiveX, formerly used to develope communication application in Visual C++ or Visual Basic, has the efficiency of programming and is widely used in the M&C(Monitoring and Control) of instruments. In this paper, we will implement M&C application capable of remote operating, and besides, develop web browser and media player in the form of ActiveX control in order to control and monitor program remotely.

This research is to construct wireless internet DGPS using MS Visual Basic Active X control for LBS. The coordinate correction method was used in this system because of convenience of both direction communication on Web. The PictureBox control and bitblt function were used in coordinate display module. The MS Comm control, MS Winsock control (TCP/IP), MS CommonDialog control, MS Sysinfo control were used in internet DGPS communication module and published on Web. Realtime internet DGPS were tested using the system which developed in this study and near realtime monitoring through this system could be performed.

현재 수많은 OPC(OLE Process Control)관련 제품들이 나와 있다. 특히, 클라이언트 제품군 가운데 가장 많이 눈에 띄는 것은 OPC 서버와 통신하여 사용자에게 장비의 정보를 전달하거나 장비를 제어 할 수 있는 OLE(Object Linking and Embedding) 컨트롤(ActiveX 컨트롤)들이다. 하지만. 이러한 OLE 컨트롤을 시스템에 적용하기 위해서는 이를 지원하는 개발 언어와 컴파일러에 대한 프로그래밍적 지식이 필요하다. 이에 본 논문에서는 프로그래밍에 대한 전문적 지식이 없이도 HMI(Human Machine Interface) / SCADA(Supervisory Control and Data Acquisition)와 같은 시스템을 구축할 수 있도록 OLE 컨트롤 컨테이너를 제공함으로써 사용자가 쉽게 디자인할 수 있는 방법을 제시한다. 본 논문에서 제안하고자 하는 OLE 컨트롤 컨테이너는 OLE/COM 기술을 기반으로 하는 OLE 컨트롤을 지원하고 웹으로의 빠른 확장을 위해 설계되었다.

본 논문에서는 컴포넌트 기술을 기반으로 한 인터액티브 멀티미디어 웹보드 시스템을 설계, 구현하고 있다. 이 시스템은 문서를 게시하고 파일을 첨부하는, 일반적인 웹 기반의 게시판을 확장한 것으로, 이러한 기본적 기능 외에 사용자로 하여금 동영상, 음성, 정지영상을 캡쳐하여 전송할 수 있도록 하는 기능을 제공한다. 이와 같은 작업은 ActiveX 컨트롤이 임베드된 웹 페이지 상에서 이루어지므로, 사용자에게는 브라우저 외의 별도의 프로그램이 요구되지 않는다. 이 시스템을 구성하는 주요한 기술적 요소에는 컴포넌트 기술, 웹 데이터베이스 기술 등이 있다. 컴포넌트 기술을 통해 자체적인 인터페이스를 가진 동영상 정지영상, 음성 캡쳐기능의 ActiveX 컨트롤을 구현하였고, MS SQL Server와 ASP를 이용한 웹 데이터베이스 기술을 통해 인터액티브한 인터페이스를 제공하였다.

The aim of this research was performance of Web-based real time DGPS using MS visual basic 6.0 Active X control. This system supported the navigation of rover by transmitting the DGPS correction information of base station via internet and monitored the moving of rover by displaying the corrected results received from rover as well as permitting Web users monitoring for rover. The Web-based DGPS server and the client system using MS visual basic 6.0 Active X control for DGPS displayed on Web-browser with the pre analysis was constructed and the system loading test via Web-browser was performed after debugging this system through the static GPS test and publishing it on Web. Also, the wireless internet DGPS test on Web by changing the distance between a base station and a rover was carried out. As the result of the test, the real time DGPS could be performed by transmitting the correction message which calculated from the server system to the client system continually. The rover could be managed by displaying the location information which received from the client system. Other users also could monitor the rover by connecting with this system via internet in real time.

E-learning education methodology using the web has been as much activated with the introduction of the internet to our society. As for the web-based education, there is no exception in case of mathematics. However, when it comes to representing math equations by using HTML image tags, a type of web marked-up language, it can be hard to represent math equations that have structural features, and to do the search, resulting in the difficulty in reusing math related applications. Therefore, based on MathML and using ActiveX control technology, a math equation generating website was designed and implemented in this study. Since this system employed ActiveX control technology, it is possible to generate math equations without the limit of time and place on the web, and to manage the program with the most up-to-dale version. And in this system, it is also possible to save the math equations generated in this system to be referred to for their reuse in the future.

This paper presents a simplified web-based simulator for digital logic circuits with which several important principles related to digital logic circuits can be understood and confirmed. The proposed simulator is implemented to have several simplified functions which are essential to the learning process of digital logic circuits. The learners by themselves simulate several digital logic circuits on the web under specific input conditions and the design/analysis of digital logic circuits can be available. The proposed simulator, combined with multimedia contents, can be used as an auxiliary educational tool and enhance the improved learning efficiency. The results of this paper can be widely used to improve the efficiency of web-based educations in the cyber space. Several simulation results are illustrated as examples to show the validity of the proposed web-based simulator.
