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    Else        tb.BackColor = vbInactiveBorder    End IfEnd Sub
