Windows Form - Multi-thread Question

Hi.

I am building a basic Windows forms application that has to synchronize
some databases. I want to make the synchronization functions run on a
separate thread than the main form so the user can still have control
of the form.
This is how I am thinking about doing it. The main object that does the
work will be created and run on a separate thread from the main form,
then fire events that will be raised in the form. Just wondering if
this is a safe way to do it.

This is a subset of the form code.

Imports System.Threading

Public Class frmMain
Inherits System.Windows.Forms.Form

Private m_tSynchronization As System.Threading.Thread
Private WithEvents m_objController As DataSynchController.Controller

Private Sub m_objController_Complete(ByVal objSynchType As
DataSynchController.Controller.SynchronizationType ) Handles
m_objController.Complete
MessageBox.Show("Complete:" & objSynchType.ToString)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
m_tSynchronization = New System.Threading.Thread(New
System.Threading.ThreadStart(AddressOf m_objController.Start))
m_tSynchronization.Start()
End Sub

end class
Thanks
