Question

I have a form that has 3 text boxes for 3 input values, along with a list box for output. I need the user to be able to input 3 different numbers and click a button to find the average. I’m not really sure how to do/approach this. Any help is greatly appreciated.

Still Stuck….

Private Sub btnAverage_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)      Handles btnAverage.Click     Dim a As Integer = CInt(txtone.Text)     Dim b As Integer = CInt(txtTwo.Text)     Dim c As Integer = CInt(txtThree.Text)     Dim average As Integer     average = (a + b + c) / 3     lstOutput.Text = average

Are you unsure about how to convert the input to numbers? If so use the CInt function.

Public Sub OnAverageClick(ByVal sender as Object, ByVal e As EventArgs) Handles AverageButton.Click      Dim input1 as Integer = CInt(textBox1.Text)     Dim input2 as Integer = CInt(textBox2.Text)     Dim input3 as Integer = CInt(textBox3.Text)     Dim average = (input1 + input2 + input3) / 3  End Sub
