Answer 1

Can you use a Dictionary(Of String, Double)?

Private values As New Dictionary(Of String, Double)

Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
    setValue(sender)
End Sub

Private Sub setValue(sender As Object)
    Dim tb As TextBox = CType(sender, TextBox)
    Dim tbName As String = tb.Name & "Strore"
    If Not values.ContainsKey(tbName) Then
        values.Add(tbName, tb.Text)
    Else
        values(tbName) = tb.Text
    End If
End Sub

Private Function getValue(sender As Object) As Double
    Dim tbName As String = CType(sender, TextBox).Name & "Strore"
    If Not values.ContainsKey(tbName) Then
        Return Double.NaN
    Else
        Return values(tbName)
    End If
End Function
