Populate Listview File From Accompanying TreeView Of Directories
Jul 20, 2009
This is a follow-up questions to the following post: [URL]
Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below
how to change the Example 1 code to work with Example 2?
Example 1

ByVal e As TreeNodeMouseClickEventArgs) _
The treeview system I am using is by Andy Bonner from the following Link, as advised I have created a new post.[url]...
Andy you were asking what it is I am trying to do so I will try explain it a little better. The treeview system you have created allows me to import / edit and save XML files based on the treeview structure that I create. What I now want to do is use the same XML files to populate buttons on a form.
So for example if I have 10 buttons on a form then on load it will look at the xml file and change the text of the buttons to whatever the main level of the treeview is.[code]...
I am using the following code to add all files and sub-directories to a Treeview control. The user can select a directory (using a folder browser dialog) and this code will add that directory, and all it's files and sub-directories, to the Treeview:

I have tried a few ways, mainly 'copying' the code from this recent codebank submission. However, I keep getting the obvious cross-thread call issue that I am adding nodes to the 'node' parameter, which is not allowed.
I am at a loss at how to do this otherwise. How can I update a Treeview like this if I have to recursively add nodes to the 'node' parameter, which is not 'available' in a separate thread?
I want to have a treeview as directory navigator I can view the first path of my dir (C:Dirmanin), I can list all files in and folders in this path, but I can't add the subfolders as node, and the subfolder of the subfolder...
Public Sub LoadFolderTree(ByVal path As String, ByVal e As System.Windows.Forms.TreeView) Dim sbasenode As System.Windows.Forms.TreeNode Try sbasenode = e.Nodes.Add(path)
I'm working on my first VB2010 project, having used VB6 up to now.In VB6, I used some library functions to implement a treeview of network PCs and their shared folders.
I've been searching, but I've not found a way to get this done with VB2010.
I have found scode to return a list of all the devices local to my network....close but not what I'm looking for.
I am trying to figure out how to dynamically populate a listview with data from a file, except I only want specific lines and columns from that file. I have code right now that works to populate the listview from the file, but it writes the whole file and I only want specific lines and columns. Here is the code I currently have to populate the listview when the form loads:
I've got 1 form that has the user enter 7 fields of data.When they click my "Save" button those values are stored in a .DAT file.On that first form there is a button that brings up a second form with a listview control.I have all the headers set up but can't figure out how to populate the listview control with the contents of the .DAT file.A friend of mine told me I may need a Do while loop but this is my first time doing this and I am so lost. I don't even know where that loop would go and whether or not I need extra variable for it.
I'm a VB beginner. The following image comes from a Mac application that I've developed. This window lists all visible files and their icons for a particular folder.
I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.
I'm running out of walls to bang my head against. Okay new windows form with a textbox, button and TreeView Populate the TreeView.nodes with the default nodes via properties
[Code]...
I want to click button1 and have the name of the childnode? Node3? placed in the textbox. Not via selection, I can do that. But via index or item number. The code I have is as follows
I have a form with a treeview and a listview. The treeview lists the folders on your system and listview shows the files in the selected folder, similar to windows explorer. I have a delete button for deleting files.
Dim i As Integer For i = 0 To lv1.SelectedItems.Count - 1 Dim csi As CShItem = lv1.SelectedItems(i).Tag
[CODE]...
When deleting multiple files a confirmation message box pops up for each file selected. I would like to have it come up once and ask 'Are you sure you want to send these 'x' files to the recycle bin?' where 'x' is the number of files selected.
how to populate a treeview from a SQL datbase. I have been looking on the web but I have not found a lot and wwhat I did find show some things that, like child nodes that I cannot find. Basically I am pulling orders from the Northwind database and want to have a branch with an order and off this branch the with the ID of the order details. So when the they click on the order node it expands to show the orderdetail ID.
I get the a branch, weiht the code below, with the order IDs but cannot get the child branch.
my code
Public Class Form2 'Dim TreeView1 = New TreeView Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
i want to make a software where i can populate the treeview from databases. that is done. but i cannot display the data in textbox corresponding to a node from database like the above link. m using vb 2008.. n the code in above link does work..
This is a problem I have been trying to conquer for some time now and haven't managed to deal with. I've looked pretty hard on Google and so on, but most of what I find there is for populating a TreeView from a database. The closest I got was a bit of C# code for populating with a list of file paths. But unfortunately the result is individual roots & branches for each item.
What I'm working on is a message template tool where I'm trying to get the nodes in the treeview, which represents the templates, to populate from an XML file. I'm using DataSets for their simplicity of working with XML. Here's a basic example of the structure of the XML which is imported to the DataSet;
So the path to each node will look like RootBranchName. I know this will no doubt require some recursion, but recursion is one thing I haven't fully grasped yet.
I am trying to populate a treeview with data from and xml document.
The loading of xml is no problem i have done that a million times over, the problem seems to be able to fill the treeview with content. My problem is this: I have a treeview with this in it:
-Race |-HQ |-TROOP |-ETC...
now... the program loads all units from xml. so when it encounters for instance a unit with a "<class>" tag containing HQ, how do i make it put it in the HQ node? I cant make it put new nodes into existing ones, only into new ones....
In vb2005, I have to load a treeview control while loading the form so make the form loading more effective therefore I use Background worker to populate treeview. I tried treeview to pass by ref and faced the error Cross thread operation not valid: Control accessed from a thread other than the thread it was created on, which makes sense.Now I want to load treeview in background and return its object then assigning it: Is this the right mechanism?

I am trying to populate a TreeView in silverlight, but I am having some difficulties - it always appears empty.I found a good tutorial (here) on how to do it, I created a new project and copied the code as it appears, using C#, and it worked perfectly. I have now tried to incorporate it into my project (which uses VB), but It doesnt work. My VB code is as follows:
how do you make a rectangle without the designer.if the powerpack rectangleshape is the only thing, how do you add it to the form, like controls.add(label) works with other controls
I have looked a long time and only found code with c# ans MSSQL, but i want to do this with VB and MYSQL.I populate my treeview with parentnodes with this code. But how do i get the child nodes to the treeview from my childtable?I have parentnodes in one table and childnodes in another.. Or is it better to have em all in one table? I want to have as many childnode levels as possible.My 2 db tables looks like this now:
Table parent looks like this: pID as integer (pk), parentName as varchar Table child looks like this: cID as integer (pk), parentID as integer, childName as varchar
This is my code now, fetching the parentnodes..
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Page.IsPostBack = False Then Dim oConn As MySqlConnection = DBConn.getConn("dbname") oConn.Open()
I'm having a little trouble figuring how to do this.I have a dataset with a single table. Each row has the following fields ProductName, Version, CompanyName
The data might look like this
Visual Studio, 2005, Microsoft Visual Studio, 2008, Microsoft Office, 2007, Microsoft
I have already populated the TreeView with a list of Company names from a separate table. Now, what I want to do is to loop through my dataset adding a single node for each product under the appropriate manufacturer. Then under each product adding a separate node for each version of that product.
I have the code below and when I try to populate the listview it populates all of the listview items but only the first subitem. No clue what I've got wrong.[code...]
I'm new to VB.NET (VB6 programmer) and from the various threads i've searched, I have put together the code below to catch duplicates in order to populate a treeview. I'm after the following result:
