    Private Sub MYEVENTHandler(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub
End Class

In your Form Load, setup the event handler for Button1. So, remove the statementHandles Button1.Click at the end of the Button1.Click procedure.

In your Form_Load place the following:
Addhandler Button1.Click, AddressOf MYEVENTHandler

In your MYEVENTHandler place the following code:
msgbox ("sonia")

In the Button2_Click, use the existing code you have, it will work.

Hope this helps.
