You can try NativeWindow to receive messages (VB code, sorry):

Imports System.Windows.Forms

Public Class MyClass: Inherits NativeWindow

Private piFormHandle As Integer = 0
Sub New()
    Me.CreateHandle(New CreateParams)
    piFormHandle = CInt(Me.Handle)
End Sub

Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
    Select Case (m.Msg)
        Case MyMessage
    End Select
    MyBase.WndProc(m)
End Sub

End Class
