Displaying controller Folder and Files in ListView

Hello I am looking for a way to display the controller folder and files in a ListView in my application. I was looking through the Controller.FileSystem methods and came
across BeginListDirectory but not sure if that is the correct one to use. Anybody got any suggestions?

How can I get more help on BeginListDirectory and examples of using this?

Newbe,
I was also looking for the same thing and I have figured it out with help from Rob Thornton at ABB US. Thanks Rob. Below is the code that I figured out from the function that you recommended.

Public Sub LoadControllerListView(ByRef lvToLoad As ListView, ByVal sFolderToLoad As String)

Dim sFileType As String = “”
Dim aFileSystem As Controllers.FileSystemDomain.FileSystem = controller.FileSystem
Dim anArray As Controllers.FileSystemDomain.ControllerFileSystemInfo()
Dim info As Controllers.FileSystemDomain.ControllerFileSystemInfo
Try
controller.FileSystem.RemoteDirectory() = sFolderToLoad
anArray = controller.FileSystem.GetFilesAndDirectories(“.”)
lvToLoad.Items.Clear()
For i As Integer = 0 To anArray.Length - 1
info = anArray(i)
If info.Name <> “..” And info.Name <> “.” Then
Dim item As New ListViewItem(info.Name)
lvToLoad.Items.Add(item)
End If
Next
Catch ex As Exception

End Try

End Sub
