Explanation / Answer

Please rate with 5 stars :) I am giving you the basic outline of creating a simple interest program in VB. I am sure that after reading this, you cna write the rest of the amount code and the variable initialization yourself :)

Public Class Form1

Private Sub btnCalculate_Click(ByVal sender As

System.Object, ByVal e As System.EventArgs) Handles

btnCalculate.Click

Dim principal, years As Integer

Dim rate, interest, amount As Single

principal = txtPrincipal.Text

years = txtYears.Text

rate = txtRate.Text

If rbSimpleInterest.Checked = True Then

interest = (principal * years * rate) / 100

Else

amount = principal * Math.Pow((1 + rate / 100), years)

interest = amount - principal

End If

txtInterest.Text = interest

End Sub
