Defines the callback of event. If you want modify argument in callback, you could use this method instead of WIN32OLE_EVENT#on_event.

ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event_with_outargs('BeforeNavigate2') {|*args|
  args.last[6] = true
}

Returns value specified by the member name of VT_RECORD OLE object. If the member name is not correct, KeyError exception is raised. If you can’t access member variable of VT_RECORD OLE object directly, use this method.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure ComObject
        Public object_id As Ineger
    End Structure
End Class

and Ruby Object class has title attribute:

then accessing object_id of ComObject from Ruby is as the following:

srver = WIN32OLE.new('ComServer.ComClass')
obj = WIN32OLE_RECORD.new('ComObject', server)
# obj.object_id returns Ruby Object#object_id
obj.ole_instance_variable_get(:object_id) # => nil

Sets value specified by the member name of VT_RECORD OLE object. If the member name is not correct, KeyError exception is raised. If you can’t set value of member of VT_RECORD OLE object directly, use this method.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    <MarshalAs(UnmanagedType.BStr)> _
    Public title As String
    Public cost As Integer
End Class

then setting value of the ‘title’ member is as following:

srver = WIN32OLE.new('ComServer.ComClass')
obj = WIN32OLE_RECORD.new('Book', server)
obj.ole_instance_variable_set(:title, "The Ruby Book")

Stop tracing object allocations.

Note that if ::trace_object_allocations_start is called n-times, then tracing will stop after calling ::trace_object_allocations_stop n-times.

Clear recorded tracing information.
