VB.net 2003 - movie ticket program

OK can someone take a look at this code and tell me what you think? I have never done any programming before, save for some low level PHP...
I am taking a VB.NET class, and this is the first project we've done
I am just worried I am screwing stuff up hardcore, so maybe someone can take a look for me.

VB Code:

Private Sub ExitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitButton.Click
        Me.Close()
    End Sub
 
    Private Sub ResetButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ResetButton.Click
        Me.NameTextBox.Text = ""
        Me.PhoneTextBox.Text = ""
        Me.AdultTextBox.Text = ""
        Me.StudentTextBox.Text = ""
        Me.ChildTextBox.Text = ""
        Me.TotalPriceLabel.Text = "$0.00"
        Me.AdultTextBox.Focus()
 
    End Sub
 
    Private Sub CalcButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles CalcButton.Click
        'set local constant for 6% tax rate
        Const conTaxRate As Single = 0.06
        'define subtotal variable
        Dim sngSubTotal As Single = (Val(Me.AdultTextBox.Text) * 6) _
        + (Val(Me.StudentTextBox.Text) * 5.25) + _
        (Val(Me.ChildTextBox.Text) * 3.75)
        Dim sngTotalPrice As Single = sngSubTotal * (1 + conTaxRate)
        Me.TotalPriceLabel.Text = sngTotalPrice
        'format the Total Price Label as currency
        Me.TotalPriceLabel.Text = Format(Me.TotalPriceLabel.Text, "currency")
        'send focus to reset button
        Me.ResetButton.Focus()
 
    End Sub

any thoughts?
