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.
is there a tool that can display the directory tree on a form like a treeview?
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?
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)
TreeView1.Nodes.Clear()

When I select a node in my treeview I have no problem seeing them in my web browser.
My problem is that when I try to collapse my tree then my last viewed document in the web browser remains visibe.
How can I ensure that when I collapse my tree my web browser will also become totallt empty?
I am not the original author of this software project and the code is poorly documented. I am mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.

I made a small recipe program and all seems to work fine. Except I seem to see some carry over or bleed over in some recipes. The layout is as follows [code]Recipe can be in Category and a Sub Category. That all seems to work great when you view the attachment "Appertizers". But when you go to the last Category you also see them there as well.The database is access and everything is correct in there, the recipes in the sub cat are right where they should be.[code]

View 2 RepliesHow i can do once I click on node1 that change to tab 3 for example
View 4 RepliesThe current code works fine on the very first fresh but after that it doesn't remember what node was clicked. For this refresh I am looking for a ini file and if found I delete the ini file and refresh the tree. The tree has only 2 parents and never anymore then that.
This first part is the timer sub
Private Sub Timer2_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Dim SelectNode As String = Me.tvFolders.SelectedNode.Name
Try
' check to see if file exist, if so do refresh then delete file
If (File.Exists(appPath & "refresh.ini")) Then
File.Delete(appPath & "refresh.ini")
[Code] .....
Now the main problem is if you click on a child in parent2 and hit refresh it is not sending Parent2 as a treenode to the search function and it doesn't remember the node clicked. But if you click on a child in parent1 it remembers the node but always refreshes to the top parent1 node. but the very first time you refresh in parent1 it works perfect. Even on the second refresh regardless of which parent you are in it never comes back with failed message from the search function.
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"

View 2 RepliesI have 2 tables that are related. Each app can relate to many apps. ie, office can be related to word, excel.[code]I would like to do the following query. I use vb.net but c# is ok.Query is to return all the apps that are not related to (1), so the result should be (4, quake) .
View 3 Replies(using VB.Net 2008) I have been using the Settings feature of vb.net to store user/application settings of my program. For small stuff it's great, but quickly starts to feel limited as the data gets more complex.Now I need to group certain settings together and organize them in a hierarchical (or relational) fashion. But from looking at the Settings tab inside of .Net, everything appears to be stored completely flat. So what's the best option for me? Some ideas I have are:
1. Use a small local database (such as an .mdb or .sdf) to store user settings. I think this could become a pain if I ever needed to update/create more settings while avoiding losing previous user data - not very flexible to change.
2. Use datasets and convert the tables to XML files.
I'm trying to find an easy to create a hierarchical directory structure that I can put in a TreeView, with two caveats:
1) The file list is from a file
2) The paths are un *nix format (e.g. /dir/dir/file rather than c:dirdirfile)
I found this ([URL]) which would do what I want...if not for the two caveats above. I can go through the process of tokenizing the paths and start creating linked lists of objects for a directory structure, but before I do that I'd like to find out if anything else is available...
I'm looking for such control in order to represent a hierarchical list that I can sort separately each set of master (parents) and his details.url...I think that such a control does not provided in .NET..Do you know for a good 3rd-party for such purpose?
