Getting file listings - vb.net

Question

I am wanting to retrieve all the files in some directories. Here is my original code:
Private Function Search(path As String, Recursive As Boolean) As Boolean
Dim dirInfo As New IO.DirectoryInfo(path)
Dim fileObject As FileSystemInfo
If Recursive = True Then
For Each fileObject In dirInfo.GetFileSystemInfos()
If fileObject.Attributes = FileAttributes.Directory Then
Search(fileObject.FullName, Recursive)
Else
lstFiles.Items.Add(fileObject.FullName)
End If
Next
Else
For Each fileObject In dirInfo.GetFileSystemInfos()
lstFiles.Items.Add(fileObject.FullName)
Next
End If
Return True
End Function
This code works well, yet it returns some directories and I am wanting to only return files.
I tried this code:
Private Sub Search(ByVal path As String, ByVal Recursive As Boolean)
if not Directory.Exists(path) then Exit Sub
Dim initDirInfo As New DirectoryInfo(path)
For Each oFileInfo In initDirInfo.GetFiles
lstfiles.items.add(oFileInfo.Name)
Next
If Recursive Then
For Each oDirInfo In initDirInfo.GetDirectories
Search(oDirInfo.FullName, True)
Next
End If
End Sub
However, i get the following error:
Access to the path 'C:\Users\Simon\AppData\Local\Application Data\' is denied.
Can someone help me with my original code, or help me access these directories with my new code?
thanks
EDIT:
I have added this module to get it working:
Imports System.Security.Principal
Module VistaSecurity
'Declare API
Private Declare Ansi Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As String) As Integer
Private Const BCM_FIRST As Int32 = &H1600
Private Const BCM_SETSHIELD As Int32 = (BCM_FIRST + &HC)
Public Function IsVistaOrHigher() As Boolean
Return Environment.OSVersion.Version.Major < 6
End Function
' Checks if the process is elevated
Public Function IsAdmin() As Boolean
Dim id As WindowsIdentity = WindowsIdentity.GetCurrent()
Dim p As WindowsPrincipal = New WindowsPrincipal(id)
Return p.IsInRole(WindowsBuiltInRole.Administrator)
End Function
' Add a shield icon to a button
Public Sub AddShieldToButton(ByRef b As Button)
b.FlatStyle = FlatStyle.System
SendMessage(b.Handle, BCM_SETSHIELD, 0, &HFFFFFFFF)
End Sub
' Restart the current process with administrator credentials
Public Sub RestartElevated()
Dim startInfo As ProcessStartInfo = New ProcessStartInfo()
startInfo.UseShellExecute = True
startInfo.WorkingDirectory = Environment.CurrentDirectory
startInfo.FileName = Application.ExecutablePath
startInfo.Verb = "runas"
Try
Dim p As Process = Process.Start(startInfo)
Catch ex As Exception
Return 'If cancelled, do nothing
End Try
Application.Exit()
End Sub
End Module

The access denied errors are occurring at Windows Libraries I think. I don't think there is any way to list the file in these libraries as they aren't actually folders.
