Failed to stop add-on

Hi all!

I've this question.

When I click "Stop" in Add-On manager, my add-on ends, but SAP Business One sends the error message "Failed to stop add-on".

My source code is:

Private Sub SBO_Application_AppEvent(ByVal EventType As SAPbouiCOM.BoAppEventTypes) Handles SBO_Application.AppEvent

Select Case EventType

Case SAPbouiCOM.BoAppEventTypes.aet_CompanyChanged

End

Case SAPbouiCOM.BoAppEventTypes.aet_ShutDown

End

Case SAPbouiCOM.BoAppEventTypes.aet_ServerTerminition

End

End Select

End Sub

Someone can help me?
