[RESOLVED] Loading specific files from folder into treeview

[Radjesh Klauke]

Hi there,

I have to load more then 8K images into a treeview, which won't work due to out-of-memory-exception, but that's not for now.
I have a list of all names of the files within the imagefolder. Specific files need to be within a different parent-node.

How do I accomplish this? (if within an array: how do I apply it within my code?)

My code (3rd party control):

   Dim lnode As New Node("Exceptions")  ' create parentnode
   .Nodes.Add(lnode)  ' add parentnode to treeview
   For Each x In My.Computer.FileSystem.GetFiles(msopath)
      Dim n As New Node(Path.GetFileNameWithoutExtension(x.ToString))
      'n.Image = Image.FromFile(x)  ' <-- comment out for now... out-of-memory exception
      lnode.Nodes.Add(n)  ' add the filnames (and the image) to the parentnode
   Next

Hi,

You need to create treenode objects to add it on the treeview control.
Say, you wanna add 10 filenames to treeview control only in parent nodes

 Private Sub AddFilesTreeview()
        If items.Count > 0 Then
            For Each item As String In items
                Dim treenode As New TreeNode()
                treenode.Name = item
                treenode.Text = item
                TreeView1.Nodes.Add(treenode) ' add the filnames (and the image) to the parentnode
            Next
        End If
    End Sub

Where items is a List<string> object that contains filenames.

I think your suggestion gave me an idea. Thanks for your input.
