Answer 1

Below is the solution:

Public Class frmMilesPerGallon
    Private Sub frmMilesPerGallon_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        txtGallon.Text = ""
        txtMiles.Text = ""
        Label3.Text = "MPG is: "
        label4.Text = "0"
    End Sub

    'Exit Events
    Private Sub btnExit_Click(sender As Object, e As EventArgs) Handles btnExit.Click
        Me.Close()
    End Sub

    'calculate button event
    Private Sub btnCalculate_Click(sender As Object, e As EventArgs) Handles btnCalculate.Click
        Dim miles As Integer
        Dim gallon As Integer
        Dim mpg As Double

        If (Integer.TryParse(txtMiles.Text, miles) And Integer.TryParse(txtGallon.Text, gallon)) Then 'Accept the miles and gallon integer value
            mpg = miles / gallon 'miles dived by gallon will get the result
            label4.Text = mpg.ToString("0.00")
        Else
            MessageBox.Show("Enter valid value!")
        End If
    End Sub

    'clear button event will clear the all form object value
    Private Sub btnClear_Click(sender As Object, e As EventArgs) Handles btnClear.Click
        txtGallon.Clear()
        txtMiles.Clear()
        Label3.Text = "MPG is: "
        label4.Text = "0"
    End Sub
End Class
