[RESOLVED] Question on implementing/using control extensions

[Gruff]

Yes,

You start a new class and just under the class name you use the keywords
'Inherits Label'.
Whatever properties, procedures and events you add to it extends what it can do.

Since you are not overriding any of the label's features the syntax should be straight forward.

Public Class TimedLabel
  Inherits Label

  Private WithEvents LabelTimer As New Timer

  Public Property Interval() As Integer
    Get
      Return LabelTimer.Interval
    End Get
    Set(value As Integer)
      LabelTimer.Interval = value
    End Set
  End Property

  Public Sub Start()
    LabelTimer.Start()
  End Sub

  Public Sub [Stop]()
    LabelTimer.Stop()
  End Sub

  Private Sub LabelTimer_Tick(sender As System.Object, e As System.EventArgs) Handles LabelTimer.Tick
    LabelTimer.Stop()
    Me.Text = ""
  End Sub
End Class

' In use

Public Class Form1
  Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    With TimedLabel1
      .Text = "This is Message to be shown for five seconds"
      .Interval = 5000
      .Start()
    End With
  End Sub
End Class
