  5. Example: MulTest - Test http://mdixon.soc.plym.ac.uk/soft131/multestX.htm

  6. Web Hardware and Software network connection Client Server Browser Application (MS Explorer, Netscape) Web-server Application (MS IIS, Apache)

  7. Request-Response Cycle <html> <head> <title>Mark Dixon's web site</title> </head> <body background="BackGround.JPG"> <font size=+3><center><b><p>Mark Dixon's web site</b></center> <font size=+2> <p>Welcombe to my web server. Please select from the following list: <ul> <li><a href="./Soft131/Index.htm">Soft131: Introduction to programming for Multimedia and Internet applications.</a> </ul> </font> </body> </html> Response Request http://mdixon.soc.plym.ac.uk/ Browser Application (MS Explorer, Netscape) Web-server Application (MS IIS, Apache)

  8. HTML • Hyper-Text Markup Language • text files • edited with notepad • with tags, e.g. • bold: <b>This will be in bold</b> • italic: <i>This will be in italic</i> • work like brackets • start/open <b> • end/close </b> • reference: http://www.willcam.com/cmat/html/crossref.html

  11. HTML - Limitations • static • cannot change • no real interaction (only links)

  12. ActiveX controls • VB can create • stand alone .exe files • ActiveX controls (.ocx files)

  14. Obtaining CLID • Run ActiveX control in browser from VB (F5) • View Source • Copy HTML <object … > tag to new html file
