[2005] Searching entire Computer for string?

[blakemckenna]

I have searched the archives for what I'm looking for and haven't had any luck. What I need to do is write a quick & dirty simple application that will search my entire computer for a string. It needs to search not just the C:\ but the DeskTop, My Documents, etc. I know I need the System.IO namespace. My only problem is determining what is the lowest level starting point for my loop? For example:

    For Each dir as Directory on Computer
         For Each fl as File in dir
              Dim str as String = ""
              Dim intPos as Integer = 0
              Open fl

              While Not fl.EndOfStream
                   str = fl.ReadLine
                   intPos = Instr(str, "String Object")
                  
                   If intPos > 0 Then
                       Do something
                   End If
              End While

              fl.Close
         Next
    Next

Thanks,
