Treeview - Pass The Fullpath To The Directory?
Jun 12, 2011
ok I have some code below as an example but I can`t seem to sort this one out, I want to pass the fullpath to the directory so that when I click the node it adds the subfolder to that node at runtime Here is my sub below I know why it`s happening but I don`t know how to fix it
Private Sub TreeView1_AfterSelect(ByVal sender As Object, ByVal e As
[code]...
this partTreeView1.Nodes(e.Node.Index).Nodes.Add(Files) is where my problem is

I've got a dataset that I maintain. The user interface to the dataset is a treeview and a listbox. The listbox shows the "items" in the treeview node that is currently selected. This works fantastic. As items are added to the dataset, I grab the fullpath property of the treeview node so I can filter and only display items that belong to the in the node that is selected. I then save all of this information to an XML file (including the fullpath of the node that the item is "in").
This all works great and does everything that I want it to. The problem comes when I load the XML file back in. I'm trying to re-create the treeview nodes exactly as they were when the document was saved. I know what the nodes are because of the fullpath property, it looks something like this: State\City\SiteName
I'm trying to create a sub (or function) to recursively create this structure. I've managed to get close, but I haven't actually got the logic yet. I've been able to get all the nodes added, but they seem to only be added at the second level. One thing that I need to worry about is duplicates. In the example above, I might have two sites in the same City. When I got close, I actually had the structure created, but the nodes were getting duplicated. For example: [Code]

I'm trying to open a file via a treeview. The nodes resemble the files and folders within a (parent)folder. I also have a textbox which has the location, including the name of the (parent)folder.
msgbox(e.node.fullpath.tostring)
This code gives me the path including the parent-node How do I get the path without the parent?

With the code below I fill my treeview:
Public Sub Popululate_Treeview()
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDatabasePath
Dim connection As New OleDbConnection(strConnectionString)
Dim dsInlognaam As DataSet = New DataSet
[code]....
The parent nodes are populated through the table "tblINLOGNAAM" The childnodes are populated by "qryINLOGNAAM_GEBRUIKER_DR" When I click the parentnode I don't want anything to happen.But when I click a childnode I would like the ID of that name (wich is stored in the table "qryINLOGNAAM_GEBRUIKER_DR" with the name "Gebruiker_ID") to show so I can make a master detail relation with a datagridview.My problem is that I cannot get the gebruiker_id from the table "qryINLOGNAAM_GEBRUIKER_DR" when I click the childnode.

I Created my own WebBrowser and now i have 2 questions:
1. Where can i set the directory that will be loaded in a TreeView
2. At Internet Explorer you can create a shortcut like Directory/iexplore.exe -google.nl
The browser goes to [URL] then, is there a way to do this in a VB.Net WebBrowser?

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 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 may be simple but I have brain freeze on just nowIf I cd into a directory from a command line and then run my executable VB.net application, is there a way to detect the directory that it was launched from. I currently have the executable in my PATH however ideally the person would cd into the directory that they were wanting the executable to act upon.

I have a treeview that is populated. The user will have some node selected in that treeview. A refresh function is called, and the program remembers the full path, so that after the treeview is cleared and repopulated, the same user selected node can be reselected for them automatically.
I have the full path of a tree node. If the full path is "nodea odeb odec" how can I automatically select that node using code?

Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController
[code].....
I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.

i have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.

I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.
