hi guys, i am working on my search button that searches for the items in my listbox1. however, i have several problems.. one, is that i do not know how am i supposed to search in folder browsing dialog and two, i cannot search for the items inside my listbox1. any comments is very much appreciated. i am just a newbie and i think this is advanced for me, so please help me! thanks alot!

this is my code:


Code:
 For Each foundFile As String In My.Computer.FileSystem.GetFiles(My.Computer.FileSystem.SpecialDirectories
_MyDocuments, FileIO.SearchOption.SearchAllSubDirectories) --> Note 1

            If listbox1.Items.Contains(foundFile) Then  --> Note 2

                listbox2.Items.Add(foundFile)  --> Note 3
            Else

                listbox3.Items.Add(foundFile) --> Note 4

            End If
        Next

note 1: i want to change the directory to a folder browse dialog not in my documents only
note 2: this are the items in the listbox that i am searching for
note 3: if found, the paths of the items will be displayed in this listbox
note 4: if it is not found, it will be displayed here
