Provide better visual feedback for disabled TextBox and ComboBox controls

When you disable a control, VB grays its contents. However, often this action goes unnoticed by the end users. Here's a routine that changes the control's BackColor property in addition to changing its Enabled property:

' enable/disable a textbox or a combobox
' (also changes its background)

Sub EnableTextBox(tb As Control, ByVal Enabled As Boolean)
    tb.Enabled = Enabled
    If Enabled Then
        tb.BackColor = vbWindowBackground
        tb.BackColor = vbInactiveBorder
    End If
End Sub
