Detecting items in the nodes of a Treeview Control

[CraigMuckleston]

I have a Treeview Control on my Windows Form with a directory structure, ie a list of nodes. This is actually a directory listing from my c drive (similiar to Windows Exlorer).

I can iterate through all the foldernames as in the code below, but how can I detect filenames that are held within the folders?

Private Sub PrintRecursive(ByVal n As TreeNode)
System.Diagnostics.Debug.WriteLine(n.Text)
MessageBox.Show(n.Text)
Dim aNode As TreeNode
For Each aNode In n.Nodes
PrintRecursive(aNode)
Next
End Sub

' Call the procedure using the top nodes of the treeview.
Private Sub CallRecursive(ByVal aTreeView As TreeView)
Dim n As TreeNode
For Each n In aTreeView.Nodes
PrintRecursive(n)
Next
End Sub

I have a TreeView control on my Windows form. It is populated by a user selecting a folder. This folder may have several subfolders (it is unknown at runtime)

I want to iterate though every folder, subfolder and items within those folders. I am using the following bit of code as supplied in the help files, but it only runs through the parent folder and child. I want to be able to run through the child's folders as well.

Private Sub ChildNodes(ByVal n As TreeNode)
System.Diagnostics.Debug.WriteLine(n.Text)
MessageBox.Show(n.Text)
Dim aNode As TreeNode
For Each aNode In n.Nodes
ChildNodes(aNode)
Next
End Sub

' Call the procedure using the top nodes of the treeview.
Private Sub ParentNodes(ByVal aTreeView As TreeView)
Dim n As TreeNode
For Each n In aTreeView.Nodes
ChildNodes(n)
Next
End Sub
