BCA0P401 - VB.NET (Practical)

UNIT Building an simple application in the vb.net environment

with form, textbox, label, numeric up down and button

1 Create a form with one textbox, one label and one button. Enter your name in textbox. On clicking of button, your name must be displaed into the label.

2 Create a form with three buttons red, green and blue. On the click of red button back color of the form will be changed to red and son.

3 Create a form, such that while running the application the form should always be shown in the middle of the screen.

4 Design on interface of simple calculator.

5 Design a form with numeric up down control. It shows only even numbers between 1 to 50.

1

6 Write a program to create a color pallet. Take three numeric up down for Red, Green and Blue color and one label. And According to the scrollbar values , the color of the label should be changed.

7 Change the icon of the form.

8 Create an application to load the image in the label.

9 Create an application with one textbox and three buttons (left, right, center). On clicking left button, alignment of

textbox should be changed to left and respectively.

10 Create an application which shows a number like 11,120 in

numeric up down.

Working with Variables, Constants, Data types and Expressions

1 Design a form that has three textboxes and radio button that calculate simple interest and compound interest.

2 Design an application which will have 2 radio buttons. One will convert the temperature from Celsius to Fahrenheit and another will Convert Fahrenheit to Celsius. Show the appropriate output depending on the user’s selection. (Use radio button to take user choice’s and use textbox to enter the value).

3 Create a loan calculator using Pmt function.

4 Take two textbox controls. Enter first name and last name in



respective textboxes and on clicking a button ,concatenate first and last name and display it on label.

5 Create an interface which allows the users to select shapes of his/her choice using radio buttons. Take parameters of that shape using textboxes and calculate the area of that particular shape.

6

Create an Employee Entry form which will include employee’s name, address, skills (take radio button for skills) and gender (take radio button for gender). On clicking submit Button should display inputted data on a label with proper Formatting.

2

7 Write a program to convert integer value into double(real).

8

Write a program to calculate the area of a circle and use pi value as constant.

9

Design and develop a project to convert an English Measurement given in Miles,Yards, Feet and Inches to a metric measurement in kilometers, meters and centimeters. Use the following formula to change the English Measurement to inches. Total inches = 63360*miles + 36*yards + 12*feets + inches Use the following formula to determine equivalent meters. Meters = total inches / 39.37

10 Write a program to convert rupees value to dollar value.

Decision Making, Repetition and multiple forms

1 Enter 5 numbers find out highest and second highest. For the highest no check it is prime or not and for second highest Calculate its Fibonacci series.

2 Create an application with a textbox in which user can enter a sentence then display

1) Number of vowels

2) Number of spaces

3) Number of digits

4) Number of special symbols

When user press “analysis” button

3 Take one textbox. Enter paragraph with multiple lines and

find out the no. of vowels and no. of digits from the given paragraph.

4 Write a program which will accept a string from user. And



then reverse the string without using inbuilt functions for string reverse. Then check whether the string is palindrome or not. Find the no of words in string. Also find out how many words starts from “a” character.

3 5 Design a form having two text boxes, combo box and a label. Make the validation so that user can enter only numbers in both textboxes, if user has entered both numerical values then make the combo box visible. The combo box has

options like ‘ADD’, ‘SUB’,’MUL’ and ‘DIV’. According to

user’s choice

From combo result will display in label.

6

Design a form which calculate the Annual salary with income tax

facilities. If monthly salary entered then calculate annual salary. Calculate the income tax as per below conditions.

Rs.0 - Rs.50000 - No tax Rs.50000 - Rs.60000 - 10% of annual income

Rs.60000 - Rs.150000 - 20% of annual income More than Rs.150000 - 30% of annual income

Also print net annual salary income after the deduction of tax in label.

7 Restrict a textbox to input only the digits.

8 Create a form with two drop down lists (combo boxes) one

for country name and another for President / Head of the

country. When the user selects a country name from combo box, corresponding President/Head name should be displayed in another combo box.

9 Design a form to accept a text from the user and then put two

text boxes to input word to find and replace. If the user clicks on find button, show index of the first occurrence of the word given in find textbox. If user clicks replace button, found

word should be replaced with the word given for replacement.

10 Write a program to transfer an item from First Listbox to

Second Listbox and from Second Listbox to First.

11 Build a calculator with all the arithmetic functions.

12 Print multiplication table into listbox. For multiplication take

value using Numeric up down.

Using menus, common dialogs, procedures, functions andarrays

1Design a form having subroutine of function with belowoperations Button1: Find out the avg. of four values.



Button2: Find out the max. of the values Button3: Find out the min. of the values

2 Create an application which provides four textboxes for accepting numbers and three option buttons to select two,three or four. Design a function adds to find addition of numbers selected using option buttons. 3Take two picture boxes on form which overlaps each other. It we click on first picture it will hide itself and shows second one and if we click on second one it will do the same. 4Accept a no from user and perform the following operations Using user defined sub routines or functions

. i. Factorial of the number ii. Odd/even

5Create MDI form. It must have File menu with option open, Close and Exit. It should also have window menu to arrange the child forms like Tile Horizontal, Tile Vertical, Cascade and Arrange Icons. 6Find out whether the number is a prime or not, using function. 7.Create MDI form. It must have File menu with option Open, Close and Exit and one picture box. Allow users to open any picture using open dialog box,and that picture should be displayed in the picture box. 8Create a text editor application. It should performs operation like cut, copy, paste and change its font and color of the selected text . 9Create a function to sort an array’s elements. 10Write a program to find minimum and maximum values from a given array.
