  2. Outlines • What is ASP? • Internet Information Services • How Does ASP Differ from HTML? • What can ASP do for you? • ASP Basic Syntax Rules • ……..

  3. What is ASP? • ASP stands for Active Server Pages ,or classical ASP • ASP is Microsoft's first server side scripting engine • It enables you to make dynamic and interactive web pages. • ASP is a program that runs inside Internet Information Services (IIS) • An ASP file can contain • Text, HTML, XML, and scripts • Scripts in an ASP file are executed on the server • The default scripting language used for ASP is VBScript, or others like JScript • An ASP file has the file extension “.asp”

  4. Internet Information Services (IIS) • Internet Information Services is an extensible web server created by Microsoft for use with Windows family.  • IIS supports: • HTTP, HTTPS, FTP, FTPS, SMTP and NNTP. • It is an integral part of Windows family since Windows NT 4.0, though it may be absent from some edition (e.g. Windows XP Home edition). • IIS is not turned on by default when Windows is installed.

  5. How Does ASP Differ from HTML? • When a browser requests an HTMLfile • the server returns the file

  6. How Does ASP Differ from HTML? • When a browser requests an ASPfile • IIS passes the request to the ASP engine. • The ASP engine reads the ASP file, line by line, and executes the scripts in the file. • Finally, the ASP file is returned to the browser as plain HTML

  7. What can ASP do for you? • Dynamically edit, change, or add any content of a Web page • Respond to user queries or data submitted from HTML forms • Access any data or databases and return the results to a browser • Customize a Web page to make it more useful for individual users

  8. Advantages of ASP … • The advantages over other technologies, are • Simplicity • speed • Provide security since the code cannot be viewed from the browser • Clever ASP programming can minimize the network traffic

  9. ASP.Net Technology • It is a unified Web development model • It includes services necessary to build enterprise-class web applications with minimum of coding. • This technology is developed under the .Net framework that is provided in the visual studio platform

  10. ASP Basic Syntax Rules • An ASP file normally contains HTML tags, just like an HTML file. • An ASP file can also contain server scripts, surrounded by the delimiters <% and %>. • The command response.write is used to write output to a browser. • Example <html> <body> <% response.write(“My first ASP script!”) %> </body> </html>

  12. Working with time and dates

  13. Formatting time and dates • FormatDateTime(Date[, NamedFormat]) • The NamedFormat argument may take the following values: • vbLongDate • vbShortDate • vbLongTime • vbShortTime

  14. Functions for time and dates • YearReturns the current year from a date - with today's date, it returns: 2014 • MonthReturnsthe current month from a date - with today's date, it returns: 1 • DayReturnsthe current day of the month from a date - with today's date, it returns:29 • HourReturnsthe current hour from a time - with the current time, it returns: 8 • MinuteReturnsthe current minute from a time - with the current time, it returns: 10 • SecondReturnsthe current second from a time - with the current time, it returns: 28

  15. Weekday function • Weekday Returns the current day of the week from a date - with today's date, it returns: 3NOTE: this function has to be called with the argument "the first day of the week" (eg. Monday or Sunday) as well- like this: Weekday(Now,vbMonday)

  16. ASP Variables • Variables are used to store information. • The example demonstrates • how to declare a variable, assign a value to it, and use the value in a text. <!DOCTYPE html><html><body> <% dim name name="Donald Duck"response.write("My name is: " & name) %></body></html>

  17. Loops “For loop” For Initializion To Expressions Statement Next

  18. For Initializion To Expressions Statement Next Loops “For loop example”

  19. Do Statement Loop {While | Until} condition Do ... Loop • Do {While | Until} condition Statement Loop OR Do Statement Loop {While | Until} condition

  20. Do .. Loop example

  21. Output

  22. Loops within loops

  23. Conditions : If ..Then..Else If conditionThen statement Else statement End If

  24. Logical Operators = Equals< Less than> Greater than<= Less than or equal to> = Greater than or equal to<> Not equal to AND OR NOT

  25. Example “AND”

  26. If ... Then ... ElseIf... Else

  27. Select ... Case Select Case Expression Case 1 statement Case 2 statement Case Else statement End Select
