[Beginner] Program to show Times Tables.

Hi,
I'm currently trying to create a program that includes a text box (to input a number into), a button and a list box that will display the times tables for the number that is entered into the text box.

The idea of the program is so that a user can enter a number into the text box, for example, the number 5 and all the times tables (up to 12) will be displayed;

1x5 = 5
2x5 = 10
etc.

I've started to code some of it but it doesn't seem to be working properly.
Can anyone help me with the coding?

Thanks in advance.

try this:

vb Code:

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
    ListBox1.Items.Clear()
    Dim number As Integer = -1
    If Integer.TryParse(TextBox1.Text, number) Then
        If number > 0 Then
            For x As Integer = 1 To 12
                ListBox1.Items.Add(x & "x" & number & "=" & number * x)
            Next
        End If
    End If
end sub
