Detaching an event Hadler Using "RemoveHandler"

We can Detach an event handler from an event using the "RemoveHandler" Key word.
Its Syntax is Similar to "AddHandler"
This is basically used to Remove Handler at run time when its not necessary

Here for one event (MouseDown) First & Second delegates will get fire, Not the Third one

Public Class frmDelegates

    'First Delegate to handel the MouseDown event
    Sub frmDelegates_MouseDown1(ByVal sender As Object, ByVal e As MouseEventArgs)
        MessageBox.Show("First Delegate Executed", String.Format("the {0} Mouse Button hit me at : ", e.Button.ToString()))
    End Sub

    'Second Delegate to handel the MouseDown event
    Sub frmDelegates_MouseDown2(ByVal sender As Object, ByVal e As MouseEventArgs)
        MessageBox.Show("Second Delegate Executed", String.Format("the {0} Mouse Button hit me at : ", e.Button.ToString()))
    End Sub

    'Third Delegate to handel the MouseDown event
    Sub frmDelegates_MouseDown3(ByVal sender As Object, ByVal e As MouseEventArgs)
        MessageBox.Show("Third Delegate Executed", String.Format("the {0} Mouse Button hit me at : ", e.Button.ToString()))
    End Sub

    'Attach Multiple Delegate for the event
    Private Sub frmDelegates_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        AddHandler Me.MouseDown, AddressOf frmDelegates_MouseDown1
        AddHandler Me.MouseDown, AddressOf frmDelegates_MouseDown2
        RemoveHandler Me.MouseDown, AddressOf frmDelegates_MouseDown3
    End Sub

End Class
