title: Add a custom property to object (i.e. Textbox) within a form at run time
body: <p>is there a simple way to add a custom property (i.e. a TextBox1) in a form at run time? What I mean is to avoid creating and using <em>custom controls</em>, just adding custom properties to the standard one.</p>
  
  <p>...so that it can be then set and accessed like</p>
  
  <pre><code>Me.TextBox1.MyCustomProperty = "my string or value"
  </code></pre>
  
  <p>Let's say in the similar way like working with structures:</p>
  
  <pre><code>Public Structure uAccess
      Dim isEditable As Boolean
      Dim isKoopPrice As Boolean
      Dim isUserEditable As Boolean
      Dim isManagerEditable As Boolean
  End Structure
  
  Dim Col1Access As uAccess
  
      With Col1Access    
          .isEditable = False
          .isManagerEditable = False
          .isSalePrice = False
          .isUserEditable = False
      End With
  </code></pre>
  
  <p>Best regards,</p>
