>You have to use the ToolboxBitmap attribute. Have a look at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskProvidingToolboxBitmapForYourControl.asp

When I try this:

<ToolboxBitmap(GetType(Label))> _
Public Class LXLabel
    Inherits System.Windows.Forms.Label

    Public Sub New()
    End Sub

End Class

the word ToolboxBitmap is highlighted. Is there some kind of reference I need to add in my project to be able to do that?
