Listing of ActiveX Controls In this topic, students will learn about the ActiveX controls that are included with Internet Explorer, Office, Access, as well as other ActiveX controls available from Microsoft. ! Working with ActiveX Controls First, explain the ActiveX control architecture. Then, demonstrate how to add an ActiveX control to a Web page using FrontPage 2000. Then, explain the <OBJECT> tag and the CODEBASE attribute. Next, explain how to set design-time properties for an ActiveX control. Then, explain Internet Component Download. Finally, explain how to build ActiveX controls. ! ActiveX Control Security This topic covers the security issues associated with the use of ActiveX controls. ! Other Active Components This topic introduces Java Applets. Then, students do a practice on adding a Java applet to a page using FrontPage 2000. It also compares ActiveX controls to Java Applets. Module 7: Adding Active Components 1 # ## # Overview ! Introduction to Active Components ! List of ActiveX Controls ! Working with ActiveX Controls ! ActiveX Control Security ! Other Active Components ! Lab: Adding Active Components ! Review Objects, such as Microsoft ® ActiveX ® controls and Java applets, play an important role in making the content on your Web site interactive. For example, you can enhance the user interface of any Web page by adding an ActiveX control, a Java applet, or both. ActiveX controls are components that use the COM technology to provide interoperability among objects. ActiveX controls are the third version of Object Linking and Embedding (OLE) controls, which provide enhancements that are specifically designed to facilitate distribution of components. In this section, you will learn about active components. You will also learn about downloading and adding an ActiveX control to a Web page. Finally, you will learn the differences between ActiveX controls and Java applets. After completing this module, you will be able to: ! Describe the ActiveX control architecture. ! Add an ActiveX control to a Web page using Microsoft FrontPage ® 2000. ! Describe how Internet Component Download functions. ! Identify the tools available for building ActiveX controls. ! Send data from an ActiveX control to a server. ! Differentiate between ActiveX controls and Java applets. Slide Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about active components, such as ActiveX controls and Java applets. You will also learn to add an ActiveX control to a Web page. 2 Module 7: Adding Active Components # ## # Introduction to Active Components ! Applications of ActiveX Controls ! What are ActiveX Controls? ! Sources of ActiveX Controls In programming, a component is a discrete part of a larger program. Usually, a component provides a specific function or a group of related functions. In object oriented programming and distributed object technology, a component is a reusable block of code that can be combined with other components stored in computers in a distributed network to form an application. Examples of a component include a button in a graphical user interface, a calculator, or an interface to a database manager. You can deploy components on different servers in a network to communicate with each other for services. A component runs within the context of a container. Examples of containers include Web pages, Web browsers, and word processors. An ActiveX control is a component that can be reused by programs within a computer or even among computers on a network. You can also create your own ActiveX controls. Slide Objective To provide an overview of Active components. Lead-in A component is a reusable piece of code that is a part of a larger program. Module 7: Adding Active Components 3 Applications of ActiveX Controls ! Popular ActiveX controls $ Calendar $ Chart $ Label (View calendar.htm from Sampapps) You can use an ActiveX control in your Web site as a small program or an animation. For example, you can download ActiveX controls from the Internet and use them in your Web pages to display a calendar, an animation, or a simple chart. The Calendar control can be used in a Web page to display a calendar. It can be used to show the current date and also select a date for a particular field in a Web page. For example, the Calendar control can be used in a Web page that requires the user to specify a date. Slide Objective To provide an overview of the applications of ActiveX controls. Lead-in ActiveX controls have a variety of applications. Delivery Tip Open the file calendar.htm from the \Inetpub\wwwroot\1912\Sam papps\Ch07 folder in Internet Explorer. 4 Module 7: Adding Active Components Applications of ActiveX Controls (continued) (View WindowsMedia.htm from Sampapps) You can add animations to a Web page by using ActiveX controls that can be downloaded as animations. Slide Objective To show the use of an animation in a Web page. Delivery Tip Open the file WindowsMedia.htm from the \Inetpub\wwwroot\1912\Sam papps\Ch07 folder in Internet Explorer. Module 7: Adding Active Components 5 Applications of ActiveX Controls (continued) (View Chart.htm from Sampapps) The Chart control can be used in a Web page to display graphical information. Slide Objective To show the use of the Chart control in a Web page. Delivery Tip Open the file Chart.htm from the \Inetpub\wwwroot\1912\Sam papps\Ch07 in Internet Explorer. 6 Module 7: Adding Active Components What Are ActiveX Controls? ! ActiveX Controls $ Reusable Components $ Multiple Language Support $ Add Functionality to Pages ! Elements of ActiveX Controls $ ActiveX Documents $ Active Scripting Controls $ Java Virtual machine (JVM) $ ActiveX Server Framework ActiveX is based on the Component Object Model (COM). With its integrated services, COM forms the foundation for developers to create powerful component-based applications. ActiveX enables software components to interoperate across networks. ActiveX controls are reusable components and provide multiple language support. ActiveX controls ActiveX controls can be downloaded as small programs for use in Web pages. These controls can also be used for any commonly performed task by an application program in the latest Microsoft Windows ® environments. ActiveX controls add functionality to Web pages. For example, you can add an ActiveX control to a Web page for features, such as charts, animations, or audio. You can create ActiveX controls using a variety of programming languages, such as Microsoft Visual Basic ® , Microsoft Visual C++ ® , and Microsoft Access. ActiveX controls are browser dependent. Currently, only Microsoft Internet Explorer 3.0 and later support ActiveX controls. Slide Objective To describe ActiveX controls. Lead-in ActiveX is a technology developed by Microsoft, which enables developers to create applications by using components. Delivery Tip Ask students to open the file Chart.htm from \Inetpub\wwwroot\1912\Sam papps\Ch07. Tell them that in the displayed Web page, an ActiveX control, Chart, has been added to graphically display a corporate sales growth. This adds functionality to the Web page. Also, tell them where all they can use this control and that there are ActiveX controls that also provide animations and audio in a Web page. Note [...]...
