Steve,

Start with making a project that will contain all your sub-classed controls. I would subclass everything you plan to use on any forms, not just the label and grid.

Namespace MyCompany.WinUI.MyClasses
    _
   Public Class MyGrid
      Inherits System.Windows.Forms.DataGrid
   ' put whatever code you need here
   
   End Class 'MyGrid
    _

   Public Class MyLabel
      Inherits System.Windows.Forms.Label
   End Class 'MyLabel
    _
   
   Public Class MyTextBox
      Inherits System.Windows.Forms.TextBox
   End Class 'MyTextBox

End Namespace 'MyCompany.WinUI.MyClasses

That should get you started ...
