SIMPLE CALCULATOR PROGRAM
This tutorial is continuation from visual basic programming part 1
In this tutorial we are going to create a simple calculator program.
The interface for the program will be as shown below
change the text properties as shown above and their names as
btn1, btn2, btn3, btn4, btn5, btn6, btn7, btn8, btn9, btn0, btnequals, btnplus, btnminus, btnmultiply, btndivide, btnclear
when a button is clicked the text in it will be displayed on the textbox1.
The text in the textbox1 must be maintained for the next click.
Double click btn1 to open the coding window and enter the code below (the one in red)
Private Sub btn1_Click(sender As Object, e As EventArgs) Handles btn1.Click
TextBox1.Text = TextBox1.Text & btn1.Text
Now run the application and click the btn1 and the application runs.
Note we are assigning textbox1 what is in it(textbox1) and the text in btn1 which is 1.
CODING THE OTHER BUTTONS
The code for the other buttons is the same only changing btn1 to btn2 and so on up to btn0.
Double click each of them and enter their codes.
run the application again ant try clicking each button.
a sneak preview of a portion of the coding window is shown below.
In the next tutorial we are going to code the plus(+) button and equals button to work for the addition.
