Practical No. 2

Aim: To calculate the sum of two numbers.

Theory: As we discussed in 1^st practical about the basics of Visual basic. Now let’s make a simple vb.net program of sum of two numbers.

For that we have to drag and release three text boxes, three labels and one Command button and change the caption by using the property window as shown below:-

After that just double click on SUM command button then you will get to the code module of your program. Shown Below:-

This is the code module where you can do coding of your application. For add two numbers take a, b, c as integers then A as text box 1, B as text box 2, c = a + b, C as text box 3 see below:-

After that click on start debugging or F5 to check whether application is working or not:-
