RemoveHandler Statement 

Removes the association between an event and an event handler.

RemoveHandler event, AddressOf eventhandler


The name of the event being handled.


The name of the procedure currently handling the event.

The AddHandler and RemoveHandler statements allow you to start and stop event handling for a specific event at any time during program execution.

For custom events, the RemoveHandler statement invokes the event's RemoveHandler accessor. For more information on custom events, see Event Statement.

Sub TestEvents()
    Dim Obj As New Class1
    ' Associate an event handler with an event.
    AddHandler Obj.Ev_Event, AddressOf EventHandler
    ' Call the method to raise the event.
    ' Stop handling events.
    RemoveHandler Obj.Ev_Event, AddressOf EventHandler
    ' This event will not be handled.
End Sub

Sub EventHandler()
    ' Handle the event.
    MsgBox("EventHandler caught event.")
End Sub

Public Class Class1
    ' Declare an event.
    Public Event Ev_Event()
    Sub CauseSomeEvent()
        ' Raise an event.
        RaiseEvent Ev_Event()
    End Sub
End Class
