Question 2

(a) What do you mean by structured error handling? Create VB .Net console application to accept 10 numbers from user and find its average. Also handle IndexOutOfRangeException.

Module Module1
    Sub Main()
        Dim counter, sum As Integer
        Dim average As Double
        Dim numberArray(10) As Integer
        Console.writeLine("Enter the Numbers : ")
        sum = 0
        For counter = 0 To 9
            Console.write("Number " & (counter + 1) & " : ")
            numberArray(counter) = Console.ReadLine()
            sum += numberArray(counter)
        Next counter
        average = sum / 10
        Console.writeLine("Average of 10 Numbers is : " & average)
        Console.writeLine("Handle IndexOutOfRangeException")
        Try
            sum = numberArray(15)
            Console.WriteLine("No Exception occured!!!")
        Catch ioore As IndexOutOfRangeException
            Console.WriteLine("Exception : Index is Out Of Range")
        Finally
            Console.WriteLine("Finally Block Executed!!")
            Console.ReadLine()
        End Try
    End Sub
End Module

(b) What is namespace? Explain it with its advantages. Create VB.Net console application to implement user defined namespace. Also give code to import it in another application.

' User Defined NameSpace

Namespace namespaceExample 
	public class classExample 
		public sub printMessage() 
			Console.WriteLine("This is the TestExample namespace!")
		End sub
	End class
End Namespace

' Importing NameSpace into Application
Imports namespaceAlias = dotNetTechnology.namespaceExample.classExample
Module Module1
	Sub Main()
		namespaceAlias.printMessage()
	End Sub
End Module

(b) What is inheritance? Create VB .Net console application to define person class and derive student and employee from it to demonstrate inheritance.

Module Module1
    Public Class person
        Public personName As String
        Public phoneNumber As String
        Public Sub showPersonData()
            Console.writeLine("Name : " & personName)
            Console.writeLine("CPI : " & phoneNumber)
        End Sub
    End Class
    Public Class student
        Inherits person
        Public rollNumber As Integer
        Public cpi As Double
        Public Sub showStudentData()
            Console.WriteLine("Roll Number : " & rollNumber)
            Console.WriteLine("CPI : " & cpi)
        End Sub
    End Class
    Public Class employee
        Inherits person
        Public empId As Integer
        Public salary As Double
        Public Sub showEmployeeData()
            Console.WriteLine("Employee ID : " & empId)
            Console.WriteLine("Salary : " & salary)
        End Sub
    End Class
    Sub Main()
        Dim studentObj As student = New student()
        studentObj.personName = "Jaydip Panchal"
        studentObj.phoneNumber = 7878314409
        studentObj.rollNumber = 61
        studentObj.cpi = 7.28
        Console.writeLine("Student Data : ")
        studentObj.showPersonData()
        studentObj.showStudentData()
        Dim employeeObj As employee = New employee()
        employeeObj.personName = "Pratik Patel"
        employeeObj.phoneNumber = 9429389214
        employeeObj.empId = 50
        employeeObj.salary = 25000
        Console.writeLine("Employee Data : ")
        employeeObj.showPersonData()
        employeeObj.showEmployeeData()
        Console.ReadLine()
    End Sub
End Module

Question 3

(a) What is Property? Explain read only, write only and read write property with suitable example.

'  Read write property Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace readWritePropertyExample
{
	public class student
	{
		private String studentName = "";
		public string sName
		{
			get
			{
				return studentName;
			}
			set
			{
				studentName = value;
			}
		}
	}
	public class readWriteProperty
	{
		public static void Main(String[] args)
		{
			Console.WriteLine("Read Write Property Simple Example");
			student studentObject = new student();
			// Set sName Property 
			studentObject.sName = "Jaydip";
			// Get sName Property 
			Console.WrileLine("Student Name : " + studentObject.sName);
		}
	}
}
    

'  Read Only property Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace readOnlyPropertyExample
{
	public class student
	{
		private String studentName = "";
		public student(String nameValue)
		{
			studentName = namevalue;
		}
		public string sName
		{
			get
			{
				return studentName;
			}
		}
	}
	public class readProperty
	{
		public static void Main(String[] args)
		{
			Console.WriteLine("Read Only Property Simple Example");
			student studentObject = new student("Arpan");
			// Get sName Property 
			Console.WrileLine("Student Name : " + studentObject.sName);
		}
	}
}
    

'  Write Only property Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace writeOnlyPropertyExample
{
	public class student
	{
		private String studentName = "";
		public string sName
		{
			set
			{
				studentName = value;
			}
		}
		public String getStudentName()
		{
			return studentName;
		}
	}
	public class writeProperty
	{
		public static void Main(String[] args)
		{
			Console.WriteLine("Write Only Property Simple Example");
			student studentObject = new student();
			// Set sName Property 
			studentObject.sName = "Pratik";
			Console.WrileLine("Student Name : " + studentObject.getStudentName());
		}
	}
}
(b) What is delegate? What is its real time usage? Give C# code to demonstrate delegate.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public delegate double doubleDelegate(double w,double h);
namespace delegateSimpleExample
{
	public class delegateClass
	{
		public static double getArea(double w,double h)
		{
			return w*h*0.5;
		}
	}
	public class delegateSimpleExampleDemo
	{
		public static void Main(String[] args)
		{
			Console.WriteLine("C# code to demonstrate delegate");
			doubleDelegate delegateObject = new doubleDelegate(delegateClass.getArea);
			Console.WrileLine("Area of Triangle is : " + delegateObject(15,20));
			Console.ReadLine();
		}
	}
}

Question 4

(a) Differentiate ASP and ASP.Net. Explain Hyperlink and Image controls with example.

<!DOCTYPE html>
<html>
<body>
<form runat="server">
<!-- Image controls in ASP.NET -->
<asp:Image runat="server" id="image1" ImageUrl="sample.jpg" ImageAlign="Left" AlternateText="Sample Image"  />
<!-- Hyperlink controls in ASP.NET -->
<asp:HyperLink runat="server" ID="hyperlink1" NavigateUrl="http://www.help2engg.com" Text="Engineering Social Network" Target="_blank" />
</form>  
</body>
</html>

(b) What is Theme? Differentiate css and skin file. Give ASP.Net code to define theme and also give code to apply it in webpage.

To define Theme you have to create first page theme and then you have to create skin file.

Steps for creating Page Themes 

1. In the Solution Explorer, right-click on your web site name and hover to Add ASP.NET then click Themes.
2. Now you will see an App_Themes folder.
3. Then create Newfolder of ThemeFolder in the App_Themes .

Steps for creating Skin file

4. Right-click on the ThemeFolder and click on Add New Item.
5. Then, you will see the Add New Item dialog box, you have to click on Skin File.
6. Type the name of the .skin file in the textbox.

Now you can add following .skin file code to created .skin file

ASP.Net code to define theme :

<asp:label runat="server" Width="100px" Height="30px" Font-Size="Large" Font-Bold="true" ForeColor="#666666" BackColor="#FFFFFF" BorderColor="#FFFFFF" />
<asp:button runat="server" ForeColor="#000000" BackColor="#000000" BorderColor="#FFFFFF" Font-Italic="true"/>
    

<!-- ASP.Net code to apply it in webpage. -->

<%@ Page Language="C#" Theme="ThemeFolder" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html>
<head runat="server">
<title>ASP.Net code to define theme and how to apply it in Web Page</title>
</head>
<body>
<font runat="server">
