  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 • 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 HTML file • the server returns the file • When a browser requests an ASP file • 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

  6. 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

  7. 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

  8. 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

  9. 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>

  10. ASP Basic Syntax Rules • ASP can format text with HTML tags <!DOCTYPE html><html><body> <% response.write("<h2>You can use HTML tags to format the text!</h2>") %> <%response.write("<p style='color:#0000ff'>This text is styled with the style attribute!</p>") %></body></html>

  11. 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>

  12. Declare an Array • Arrays are used to store a series of related data items. • The example demonstrates how to declare an array that stores names. <!DOCTYPE html><html><body> <% Dim famname(5),ifamname(0) = "Jan Egil"famname(1) = "Tove"famname(2) = "Hege"famname(3) = "Stale"famname(4) = "Kai Jim"famname(5) = "Borge" For i = 0 to 5response.write(famname(i) & "<br>") Next %></body></html>

  13. Example of Loop <!DOCTYPE html><html><body> <% dim i  for i=1 to 6response.write("<h" & i & ">Heading " & i & "</h" & i & ">") next %></body></html>

  14. Time-based Time-based greeting using VBScriptThis it will display a different message to the user depending on the time on the server.

  15. <!DOCTYPE html><html><body> <% dim h h=hour(now()) response.write("<p>" & now())response.write("</p>") If h<12 thenresponse.write("Good Morning!") elseresponse.write("Good day!") end if %></body></html>

  16. ASP Forms • Get • A form with method="get“ is how to interact with the user, with >>>> Request.QueryStringcommand. • Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send. • Post • A form with method="post“ is how to interact with the user, with >>>> Request.Form command. • Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send. • Radiobuttons • A form with radio buttons is how to interact with the user, through radio buttons, with >>>> Request.Form command.

  17. ASP Forms – Get / Post method <!DOCTYPE html><html><body> <form action="demo_reqquery.asp" method="get"> Your name: <input type="text" name="fname" size="20" /> <input type="submit" value="Submit" /> </form> <% dim fnamefname=Request.QueryString("fname") ((request.form)) If fname<>"" ThenResponse.Write("Hello " & fname & "!<br>")Response.Write("How are you today?") End If %></body></html>

  18. Radiobuttons <!DOCTYPE html><html> <% dim cars cars=Request.Form("cars") %><body><form action="demo_radiob.asp" method="post"><p>Please select your favorite car:</p><input type="radio" name="cars"<%if cars="Volvo" then Response.Write("checked")%> value="Volvo">Volvo</input><br><input type="radio" name="cars"<%if cars="Saab" then Response.Write("checked")%>value="Saab">Saab</input><br><input type="radio" name="cars"<%if cars="BMW" then Response.Write("checked")%>value="BMW">BMW</input><br><br><input type="submit" value="Submit" /></form> <% if cars<>"" thenResponse.Write("<p>Your favorite car is: " & cars & "</p>") end if %></body></html>

  19. Check box <!DOCTYPE html><html><body> <% fruits=Request.Form("fruits")%> <form action="demo_checkboxes.asp" method="post"> <p>Which of these fruits do you prefer:</p> <input type="checkbox" name="fruits" value="Apples"<% if instr(fruits,"Apple") then Response.Write("checked")%>> Apple <br> <input type="checkbox" name="fruits" value="Oranges"<%if instr(fruits,"Oranges") then Response.Write("checked")%>> Orange <br> <input type="checkbox" name="fruits" value="Bananas"<%if instr(fruits,"Banana") then Response.Write("checked")%>> Banana <br> <input type="submit" value="Submit"> </form> <% if fruits<>"" then %>   <p>You like: <%Response.Write(fruits)%></p> <% end if %></body></html>

  20. ASP Sending e-mail with CDOSYS • CDOSYS is a built-in component in ASP. This component is used to send e-mails with ASP. • CDO (Collaboration Data Objects) is a Microsoft technology that is designed to simplify the creation of messaging applications. • CDOSYS is a built-in component in ASP.

  21. Examples – ASP Sending e-mail

  22. ASP – Date & Time • <!DOCTYPE html><html><body> <%response.write(FormatDateTime(date(),vbgeneraldate))response.write("<br>")response.write(FormatDateTime(date(),vblongdate))response.write("<br>")response.write(FormatDateTime(date(),vbshortdate))response.write("<br>")response.write(FormatDateTime(now(),vblongtime))response.write("<br>")response.write(FormatDateTime(now(),vbshorttime)) %><p> Syntax for FormatDateTime: FormatDateTime(date,namedformat).</p></body></html>

  23. To be continued…

  24. ASP text box types ! • The TextMode property accepts the following three values: • SingleLine— displays a single-line input field. • MultiLine— displays a multi-line input field. • Password— displays a single-line input field in which the text is hidden. • A basic TextBox:<asp:TextBox id="tb1" runat="server" />A password TextBox:<asp:TextBox id="tb2" TextMode="password" runat="server" />A TextBox with text:<asp:TextBox id="tb4" Text="Hello World!" runat="server" />A multiline TextBox:<asp:TextBox id="tb3" TextMode="multiline" runat="server" />

  25. Find the output example ! <form runat="server"> <asp:DropDownList id="drop1" runat="server"> <asp:ListItem>fall</asp:ListItem> <asp:ListItem>spring</asp:ListItem> <asp:ListItem>summer</asp:ListItem> </asp:DropDownList> <asp:Button Text="Submit" OnClick="submit" runat="server"/> <p><asp:label id="mess" runat="server"/></p> </form>

  26. Find the output example ! <form runat="server"> Enter your name: <asp:TextBox id="txt1" runat="server" /> <asp:password id="pass1" runat="server" /> <p><asp:Label id="lbl1" runat="server" /></p> <asp:Calendarrunat="server" /> <asp:ButtonOnClick="submit" Text="Submit" runat="server" /> </form>
