Practical: 1 - Write the Steps for configure IIS with Asp.Net
Installation of IIS in Windows XP
Windows XP does not generally have IIS installed by default, so it will probably have to be
done manually. To do so, follow these steps:
Step: 1 – Click on Start Button → Go to Control Panel, and open Add/Remove Programs.

Step: 2 – In the left side panel, click on Add/Remove Windows Components.


Step: 3 – In the window Components Wizard, find the 'Internet Information Services (IIS)'
option and check it.

Step: 4 – Click on "Details" button. Ensure that 'World Wide Web Service' is checked. Select
other options as per your need and then click "OK".


Step: 5 - Click on "Next" Button, the required files will begin to copy. we may be prompted
to insert the original Windows XP install CD, if we have not given windows XP Installation
disc or installation source.

Step: 6 - Once the file copy is complete, click "Finish".


Now, In Control Panel, open 'Administrative Tools' and IIS should now be installed.

How to test IIS (Web Server) is successfully installed or not?
Open Web Browser and type http://localhost in the Address Bar. If web browser shows the
information about your IIS, then your web server (IIS) installed successfully.

Installation of IIS in Windows Vista and Windows 7
Step: 1 – Click on Start Button → Go to Control Panel.

Step: 2 – In the Control Panel click on programs or in the left side panel, select Classic View
and Open Programs and Features.

Or
Step: 3 – In the left side panel, click on “Turn Windows features on or off” link. Or click on
“turn on or off windows features”.

Step: 4 - You may receive the Windows Security warning. Click Allow to continue. The
Windows Features dialog box is displayed.

Step: 5 - Expand Internet Information Services. Additional categories of IIS features are
displayed. Select Internet Information Services to choose the default features for
installation. Expand the additional categories displayed, and select any additional features
we want to install, such as Web Management Tools, FTP etc.


Step: 6 – Click “OK” button at the bottom, and wait for installation to complete.

IIS is now installed with a default configuration on Windows Vista or Windows 7.
Next, you can use Internet Information Services Manager to manage and configure IIS. To
open IIS Manager, click Start, type inetmgr in the Search Programs and Files box, and then
press ENTER.

Installation of IIS on Windows 8
Step: 1 - Press the Windows + R key combination to bring up a run box, then type
appwiz.cpl and press ok or press enter.

Step: 2 - This will open the Program and Features part of Control Panel, on the left hand
side click on the “Turn Windows features on or off” link.


Step: 3 - Now click on the Internet Information Services check box. Select other options as
per your need and then click "OK".

Step: 4 - Click “OK” button at the bottom, and wait for installation to complete.


How to test IIS (Web Server) is successfully installed or not.
Open Web Browser and type http://localhost in the Address Bar. If web browser shows the
information about your IIS, then your web server (IIS) installed successfully.

IIS 8 Successfully Installed on Windows 8.

Practical: 5 - Write an Asp.Net program using different namespaces.
First add a class file.
Right click on your web application from the solution explorer, click on add new item
Now we can see ‘add new item’ window. Select class and type the name of your file then
click on add button.

Now create your own custom namespace and class in the class file.

Practical: 13 - Write an Asp.Net Program to demonstrate use of Master Page using
Themes.
How to Create Theme:
Step 1: Right Click on your web site.

button. Your skin file is created.
Step: 8 now, Double click on skin file and write the code below:
Code: myskin.skin
<asp:TextBox runat="server" ForeColor="blue" Font-Size="30px" />
<asp:DropDownList runat="server" BackColor="blue" Width=”200px” />
<asp:Label runat="server" ForeColor="yellow" BackColor="blue" Font-Size="50px" />
Step: 9 open Source view of your .aspx file and write the code below or put textbox,
dropdownlist and label control in the web form.
Code: MasterPage.master
<asp:ContentPlaceHolder id="head" runat="server">

</asp:ContentPlaceHolder>
</head>
<body>
<div>
<h1>Master Page with Theme</h1>
<asp:Label ID="Label1" runat="server" Text="Label Control in Master Page...">
</asp:Label>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
<p>Demostration of Master page with Theme.</p>
</div>
</form>
</body>
</html>
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master"
AutoEventWireup="true" CodeFile="practical-131.aspx.cs" Inherits="practical_131"
Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1"

Asp.Net Program to demonstrate the various methods of Dataset Object.
Asp.Net Program to demonstrate Login Page using Database.

How to create and Attach Database in our website.
First of all add App_Data Folder in our website. Here we will use database file and attach the
database to our web site.
Step: 1 In Solution Explorer: Right Click on Our website root -> goto Add ASP.NET Folder > and click on App_Data.

Step: 2 In Solution Explorer Right Click on App_Data -> click on Add New Item
