Hey,

  • If you do not need a button to use to calculate sum, you can code that for the ‘key press’ action after you fill the second textbox. Below is a sample code for resolve your problem.
  •   Private Sub TextBox2_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox2.KeyPress

        Dim num1, num2, tot As Double
        num1 = Val(TextBox1.Text)
        num2 = Val(TextBox2.Text)
        tot = num1 + num2
        TextBox3.Text = tot
    End Sub

Hope this will work.

  • There are many ways to program your project  to get the result that you want. If you are a beginner, I hope I can be of help with a simple explanation of VB "event" to get the sum of two numbers encoded in your text boxes.
  • Since you want the sum to be shown without using a button to trigger the computation, we would use the change event on each text boxes.
