View 3 RepliesI have something that is working for the most part, but I'm having some trouble with restricted-access folders.
The code I'm using is as follows:
Imports System.IO
Public Class frmMain
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
For Each drive In DriveInfo.GetDrives
[Code] .....
For testing purposes I replaced this section...
If drive.IsReady Then
PopulateTree(drive.ToString, TreeView1.Nodes(i))
End If
...with this...
If drive.toString = "L:"
PopulateTree(drive.ToString, TreeView1.Nodes(i))
End If
And it worked fine for that drive. The L: is a removable USB drive by the way.
However, with the original code I get debug errors on some folders because they are access-restricted. Is there any way to ignore those particular folders and show the rest?
This is driving me crazzyy. I need a simple way to display all of the folders and subfolders of an FTP directory in a treeview, similar to the layout of Windows Explorer. Here's the code I have:

The code is total crap... causes my app to hang. Pretty sure infinite recursion is the cause.
I would like to identify a treenode before I repaint a tree and wish the new tree paint to show that particular node in the display window.
Dim StartNode as treenode=tree.selectednode
Then perform repaint on tree from database How to scroll up to StartNode automatically.
I can't find how to do it. So, I want to ask it to you guys. I have a form that had included a ListBox, a TreeView and a Button. In ListBox has a same dynamically created domain URL's Like this;

View 3 RepliesI'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?
View 3 RepliesI'm just starting out at vb.net but have done programming before. i am trying to use a treeview to display information in a seperate table on the same form dependant on which nod of the tree is clicked. Secondly is it possible to import the information from an excel spreadsheet or does the information have to come from an access table.

I want to select a node from my tree view, whatever I select is going to get a record from my database, I need a unique ID in each node so it will collect the correct document relating to the selected node.
How can I do this? the name of the node maybe used more than once? Each row in my database has an ID and Title, the title is the name I guess the ID being unique needs to be tied in somehow.
I have a treeview which i populate dynamically using an XML Datasource. The leaf nodes in the TreeView attempt to open a URL in an iframe within the page.This all works fine, but i would like the iframe to be hidden until the point the leaf node is selected.what event is triggered when the nodes are clicked?? I tried the SelectedNodeChanged event but this doesnt seem to get triggered!
UPDATE - The TreeView code is shown Below
<asp:TreeView ID="TreeView1" runat="server" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" DataSourceID="XmlDataSource2" AutoGenerateDataBindings="False">
<DataBindings>
[code]....
While fiddling with my code i noticed that when i remove the NavigateUrlField="URL" from my code the tree triggers the SelectedNodeChange event, But does not Trigger if NavigateUrlField="URL" is put back in.
I have a webbrowser control & a treeview control...once I load a website I create a HTML DOM tree representation of the website using the code below...What I want to do now, is the following:mouse over any HTML element, which will then select the corresponding tree node on the HTML DOM Tree select any tree node and have the corresponding HTML element highlight, with a red border around it?
Private Sub UpdateDOM(ByVal HTMLDocument As mshtml.IHTMLDocument3)

I am trying to find a quick, step by step tutorial on on to implement a tree view for my intranet that will show all the computer accounts in my domain.

View 1 RepliesI am loading the directories from my C drive into a treeview using the code below. It takes forever due to the number of folders. Is it possible to have this only populate down 1 level and then use a NodeMouseClick Event to drill down further, in the same treeView, if the user desires to do so? How would I amend this code to do this?

i have a treeviev and listbox.i want to display the selected contents of treeview into the listbox.my code is working for file but not for folder. means i want, if the all contents of folder ABC(i.e all files) are selected then in listbox i want to show the only path of folder not the seperate path of each file.
View 1 RepliesI am trying to write code to save (in a text file) a list of folders/files that are contained in a specified folder. I want the list to be formatted to illustrate the folder tree structure by indenting sub-folders and there related files according to their relationship to the base folder.
I found and incorporated a recursive function for listing file & folders. This works fine for generating the list, but I am having difficulty with code to determine the sub-directory level relative to the base folder. the code that I have included below sort of works.......The problem seeme to be when going from a folder that is multiple levels up? from the base to one that is only one level from the base. Refer to my sample output. This should not be as difficult as I seemed to have made it, but recursion kinda blows my mind.
Code:
' The following function call is in a button handler
GetFilesFolders(txtBaseFolder.Text)
Public Sub GetFilesFolders(ByVal path As String)

im trying to make it so that if a tree thing is clicked it will change the photo in a picture box. i already have it done but its a long code and i need almost 80 photos. in order to do that i will have to repeate this code 80 times
If e.Node.Text = "Blue tiger striped G36E" Then PictureBox1.Image = My.Resources.tigerg36e End If its on a key down event for the tree view, how can i get it so that i only need 1 line of code like
PictureBox1.Image = My.Resources + e.Node.Text so that if "Blue tiger striped G36E" is selected it will display a picture called "Blue tiger striped G36E" also if "Map" is selected it will display the photo that is called "map"
I have a TreeView in my form which suffers from slow build-time (i.e. it takes forever to load as it drills down into all subdirectories). It effectively loads a treeview control and then allows the user to select a node and populate a ListView control with the files within the given directory node. It populates based on the treeView1_NodeMouseClick event.how I can populate the treeview only down to 1 level only and still have my NodeMouseClick event work in its current form?Effectively I want it to populate down to 1 level on load and then down to 1 level upon clicking each node thereafter
Private Sub PopulateFolderTreeView()
Dim rootNode As TreeNode
Dim info As New DirectoryInfo("C:Documents and SettingsOur AccountMy Documents")[code].....

adapted from Major treeview/list view head ache I managed to make the treeview display the folder and the sub folders... but it isn't very hierarchial. Check attached pictures. Image1 shows how it is and image2 shows how I want it to be. Can anyone tell me how to get it to look like image 2?...Image2 was made in Windows Explorer. Image1 is a screenshot of the runing program that I am trying to make. I have been googling around but no luck so far. Practically I think what I shoul be asking is how to create child nodes of subfolders. The program is going to copy whatever the user checks in the treeview into another folder chosen by the user. I am using Visual Basic 2008 Express.
I need to have tree view display a Folder View of a directory. I also Need to be able to create/rename folders in this view. Potentially even copy files to the newly created/renamed folders.
