Getting started with VB.net

Hi,

First you would need to design the application by placing four textboxes and using Properties window set their Names as:
txtPrincipal  for Principal Balance
txtRate        for Interest Rate
txtYears      for Number of years
txtAmount   for Payment Amount

and a Button:
btnCalculate   for Calculating

then in the .vb file you need to add the following calculation code:

Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
        txtAmount.Text = txtPrincipal.Text + (CDbl(txtPrincipal.Text) * CDbl(txtRate.Text) * CDbl(txtYears.Text)) / 100.0
End Sub

hope this helps.

I've added all of the textboxes and a button.  This is the code in the form on the code view.  I'm not sure I understand what's going on, where to declare my variables.

Public Class Form1
    Inherits System.Windows.Forms.Form

    Private Sub GroupBox1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBox1.Enter

    End Sub
End Class
