[RESOLVED] Data Tree View help!

This is somewhat of a multi part question, let me start off by explaining what I'm trying to do. I have an organized folder system with data files in them. Each folder has a set structure to their naming, and can contain sub folders and files. It will be a jagged directory system. I'm trying to import their structure into a TreeView.

I have the workings of a recursive system that adds all files and folders into a ViewTree, however they aren't organized by parent/child. So I get this...
-C:\Temp
-C:\Temp\Data
-C:\Temp\file1.txt
-C:\Temp\file2.txt
-C:\Temp\Data\file3.txt
-C:\Temp\Data\file4.txt
etc........


How would I go about parsing the directory paths, and include them into a parent/child relationship... looking like this
+Temp
--file1.txt
--file2.txt
-+Data
---file3.txt
---file4.txt


Also I when the line item is selected, I need to know which file is selected so I can use it's full path to call up data (using an API) based upon the it's full root path.

You may need to refine this a little but it should get you well and truly on the way:

Code:

---

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.AddNode("C:\Temp")
        Me.AddNode("C:\Temp\Data")
        Me.AddNode("C:\Temp\file1.txt")
        Me.AddNode("C:\Temp\file2.txt")
        Me.AddNode("C:\Temp\Data\file3.txt")
        Me.AddNode("C:\Temp\Data\file4.txt")
    End Sub

    Private Sub AddNode(ByVal path As String)
        Dim labels As New Stack(Of String)

        Do Until IO.Path.GetPathRoot(path) = path
            labels.Push(IO.Path.GetFileName(path))
            path = IO.Path.GetDirectoryName(path)
        Loop

        Dim nodes As TreeNodeCollection = Me.TreeView1.Nodes
        Dim node As TreeNode
        Dim label As String

        While labels.Count > 0
            label = labels.Pop()

            If nodes.ContainsKey(label) Then
                node = nodes(label)
            Else
                node = nodes.Add(label, label)
            End If

            nodes = node.Nodes
        End While
    End Sub

End Class

Note that that AddNode method will actually add all parent nodes automatically, so you don't need these lines:

Code:

---

Me.AddNode("C:\Temp")
Me.AddNode("C:\Temp\Data")

---

That said, you may then have to manipulate the ordering to get the subfolders listed before the files. I'll let you mess with that.

Works Perfectly! Didnt know about the "push", "pop" thing. Need to look at those more closely!
