#### Adding text fields and a button

We download from the bar on the left (Toolbox) three text boxes (TextBox), two labels (Label) and a button (Button), afterards we arrange them in the window of the application. After that we chagne the names of each of the controls. This is done from the window “Properties” on the right, by changing the field (Name):

• Names of the text boxes: textBox1, textBox2, textBoxSum
• Name of the button: buttonCalculate
• Name of the form: FormCalculate

We change the headings (the Text property) of the controls:

• buttonCalculate -> Calculate
• label1 -> +
• label2 -> =
• Form1 -> Sumator
