Program 1: Develop a console application to explain

hierarchical inheritance

Solution:

using System;using System.Collections.Generic;using System.Linq;using System.Text;

namespace Assignmentprog1{ class Program

{ static void Main(string[] args)

{ ashok t = new ashok();

t.print1();t.print2();t.show();

honda c = new honda();c.show1();c.show2();c.show();

}

} class vehicle

{ public void show()

{ Console.WriteLine("I am the Biggest and the heaviest");

}}

class car : vehicle{

public void show1(){

Console.WriteLine("I m a small running home of all humans");}

}

class truck : vehicle{

public void print1(){

Console.WriteLine("all big transporters use me");}

} class honda : car

{ public void show2()

{ Console.WriteLine("My best IS HONDA CIVIC");

}

} class ashok : truck

{ public void print2()

{ Console.WriteLine("I make big vehicles in India");



Console.ReadLine();}

}

}

Output:

Program 2: Develop a windows application to form a

calculator which performs all arithmetic operations.

Solution:

Properties:Control PropertyName

Label1 First num

Label2 Second num

Label3 Result

Label4 result



Radiobutton 1 Add

Radiobutton2 Subtract

Radiobutton3 Multiply

Radiobutton4 Divide

Button1 Do

Button2 Clear

Coding:

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;

namespace WindowsFormsApplication2{ public partial class Form1 : Form

{ public Form1(){

InitializeComponent();}

private void textBox1_TextChanged(object sender, EventArgs e){

}


}


}

private void radioButton1_CheckedChanged(object sender, EventArgs e){

}


}

private void radioButton3_CheckedChanged(object sender, EventArgs e)



{

}


}

private void button2_Click(object sender, EventArgs e){

if (radioButton1.Checked==true){

int a, b, c;a = Convert.ToInt16(textBox1.Text);b = Convert.ToInt16(textBox2.Text);c = a + b;label4.Text = Convert.ToString(c);

} if (radioButton2.Checked==true)

{

int a, b, c;a = Convert.ToInt16(textBox1.Text);b = Convert.ToInt16(textBox2.Text);c = a - b;label4.Text = Convert.ToString(c);

}


int a, b, c;a = Convert.ToInt16(textBox1.Text);b = Convert.ToInt16(textBox2.Text);c = a * b;label4.Text = Convert.ToString(c);

}


int a, b, c;a = Convert.ToInt16(textBox1.Text);b = Convert.ToInt16(textBox2.Text);c = a / b;label4.Text = Convert.ToString(c);

}}


textBox1.Text = " ";textBox2.Text = " ";label4.Text = " ";

}}

}



Output:

Program 3:Design a MDI text editor(any child window)application using c# windows application.

Solution:



Coding:

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;

using System.Linq;using System.Text;using System.Windows.Forms;

namespace WindowsFormsApplication1{ public partial class Form1 : Form

{ private int childNumber = 0; public Form1()

{InitializeComponent();

}


Form child = new Form();child.MdiParent = this;child.Text = "Harsh" + childNumber++;child.Show();

}}

}

Output:



Problem 4:Design a windows application that illustrate list

control and user defined dialog box for displaying the first

name, last name, job title of the employee in a company.

Write the steps in designing the application withproperties designed.

Solution:

Properties:

Control Property name

Label1 First Name

Label2 Last Name

Label3 Job TitleButton1 Ok

Button2 Cancel



Steps:

1. At first we need a private member to hold the employee

object the dialog is working on.

2.Then we are using the public employee property. So that

Other code use dialog can get the employee data.

Coding:

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;

namespace Employee1{ public class employee

{ public string FirstName; public string LastName; public string JobTitle; public override string ToString()

{ return FirstName + " " + LastName + " " + JobTitle;

}};

public partial class Dialog : Form{

public Dialog(){

InitializeComponent();}

private employee _employee = null;

public employee staffMember{

get{

if (_employee == null){

_employee = new employee();

}_employee.FirstName = textBox1.Text;



_employee.LastName = textBox2.Text;_employee.JobTitle = textBox3.Text;

return _employee;}

set{

_employee = value;textBox1.Text = _employee.FirstName;

textBox2.Text = _employee.LastName;textBox3.Text = _employee.JobTitle;

}

}}

}

3. Now double click the Form1.cs in the solution explorer to

bring up the main form in the designer window. Drop

some control onto the form so that it looks like..



Properties:

Control Property Name

List Box Employee ListLabel1 firstName

Label2 LastName

Label3 JobTitle

Button1 Add

Button2 Edit

Button3 Delete

4.The Code is written to add new item to the list box.

Double click the add button to drag into its click event

Handler. All we need to do here is show the dialog and

then add the new employee object,it creates into the

list box.

Coding:

using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;

namespace Employee1{

public partial class Form1 : Form{

public Form1()




}


dialog newEmployeeDialog = new dialog(); if (newEmployeeDialog.ShowDialog()==dialogResult.OK)

{ listBox1.Items.Add(newEmployeeDialog.staffMember);}

}


if (listBox1.SelectedIndex == -1) return; if (MessageBox.Show("Really Delete", "Delete", MessageBoxButtons.YesNo,MessageBoxIcon.Question) == dialogResult.Yes)

{listBox1.Items.Remove(listBox1.SelectedItem);

}

}


if (listBox1.SelectedIndex == -1) return; int employeeNum = listBox1.SelectedIndex; dialog newEmployeeDialog = new dialog();

newEmployeeDialog.staffMember = (employee)listBox1.SelectedItem; if (newEmployeeDialog.ShowDialog()==dialogResult.OK)

{listBox1.Items.RemoveAt(employeeNum);listBox1.Items.Insert(employeeNum, newEmployeeDialog.staffMember);listBox1.SelectedIndex = employeeNum;

}

}

private void listBox1_SelectedIndexChanged( object sender, EventArgs e){

if (listBox1.SelectedIndex!=-1)

{ employee currentEmployee=(employee)listBox1.SelectedItem;

textBox1.Text = currentEmployee.FirstName;textBox2.Text=currentEmployee.LastName;textBox3.Text = currentEmployee.JobTitle;

} else

{textBox1.Text=textBox2.Text=textBox3.Text= "";

}}

private void Form1_Load(object sender, EventArgs e){

}

}



}

Program 5: Design a windows application to illustrate tree

view control to list out odd and even number. Also design

to add, image, colour, etc.

Solution:



Steps:

1. Open a new form and drag button1 called load.

2.Drag tree view from toolbox.

3.Double click on load button and write the coding.

Coding:

using System.Data;using System.Drawing;

using System.Linq;using System.Text;using System.Windows.Forms;

namespace treeview{ public partial class Form1 : Form

{ public Form1()


}

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e){

}




treeView1.Nodes.Clear();treeView1.ShowNodeToolTips = true;

TreeNode evenNumbers = treeView1.Nodes.Add("even numbers"); TreeNode oddNumbers = treeView1.Nodes.Add("odd numbers"); /* TreeNode evenNumbers = treeView1.Nodes.Add("even", "even numbers", 0, 1);

TreeNode oddNumbers = treeView1.Nodes.Add("odd", "odd numbers", 0, 1);*/

evenNumbers.BackColor = Color.Red;evenNumbers.ForeColor = Color.Yellow;evenNumbers.ToolTipText = "the evens";oddNumbers.BackColor = Color.Blue;oddNumbers.ForeColor = Color.Red;oddNumbers.ToolTipText = "the odds";

for (int i = 1; i < 500; i++){

if (i % 2 == 0){

evenNumbers.Nodes.Add(i.ToString());}

else

{ oddNumbers.Nodes.Add(i.ToString());}

}

}}

}
