How to: Search files from a certain directory with Progressbar + Backgroundworker
Hello Everyone, Admin. I'm new to this Forum and i want to ask how to search files from a certain directory with progressbar & background worker? 

Code: (from the Admin-(Brandonio)) :

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


    End Sub

    Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork

        Dim directory = "Path"
        Dim files() As System.IO.FileInfo
        Dim dirinfo As New System.IO.DirectoryInfo(directory)
        files = dirinfo.GetFiles("*", IO.SearchOption.AllDirectories)
        For Each file In files

    End Sub

But whenever i click the button, i get an error saying : Cross-thread operation not valid: Control 'ListBox1' accessed from a thread other than the thread it was created on.
I'm new in VB.NET and i'm making an application that cleans up the Temporary folder.
Thank you. and uh, i like this forum.
