VB.net - multithreading question

[VaxoP]

I havent got vb.net yet, thinking of purchasing it.

im just wondering, will

Public Sub thread1()
        WB.Navigate "http://www.google.ca"
        Do: Doevents: Loop until wb.busy = false
        debug.print "Done"
    End Sub
 
    Public Sub thread2()
        WB2.Navigate "http://www.google.ca"
        Do: Doevents: Loop until wb2.busy = false
        debug.print "Done"
    End Sub
 
    Public Sub AllThread()
        'Combine the two subs in one sub so they can be 
        'fired at once
        Me.thread1()
        Me.thread2()
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim thrd As Threading.Thread
        thrd = New Threading.Thread(AddressOf AllThread)
        thrd.Start()
 
    End Sub

will that Doevents run only for that specific thread? so that each thread will wait until the browser is done loading? or will once thread1 execute, the doevents will make the whole program wait for it to be done?
