Invoking ListView problem....

[tassa]

Hello,

This is my code:

Private Sub Button2_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Me.FolderBrowserDialog1.ShowDialog()
 
        If Me.FolderBrowserDialog1.SelectedPath <> String.Empty Then
            Me.TextBox2.Text = Me.FolderBrowserDialog1.SelectedPath
            Dim deleg As New Thread(AddressOf UpdateFileList)
            deleg.Start()
        End If
 
        Me.FolderBrowserDialog1.Reset()
    End Sub
#End Region
 
    Private Sub UpdateFileList()
        Try
            Dim _filenames As ReadOnlyCollection(Of String) = My.Computer.FileSystem. _
            GetFiles(Me.TextBox2.Text, FileIO.SearchOption.SearchAllSubDirectories)
 
            For Each filename As String In _filenames
                Me.ImageList1.Images.AddStrip(ExtractAssociatedIcon(filename).ToBitmap)
                If ListView1.InvokeRequired Then
                    Me.ListView1.Invoke(New UpdateProgressCallBack(AddressOf UpdateFileList))
                Else
                    ListView1.Items. _
                    Add(filename, imageIndex:=Me.ImageList1.Images.Count - 1) _
                    .SubItems.Add(filename)
                End If
            Next
        Catch ex as Exception
 
        End Try
    End Sub

If I wanted to add 3 icons, the LV would add them like it normally would, but then, for some reason, it enters the loop again and that's when it throws this error:

ex = {"Cross-thread operation not valid: Control 'ListView1' accessed from a thread other than the thread it was created on."}

I don't understand why, because I'm invoking the LV...

Thanks in advance!
