I have a treeview, it lists all folders and subfolders and files within each folder. Now, I want to display each file / folders associated icon. I am using the SHGetFileInfo API, it works sort of, what I mean by sort of is, that my treeview doesn't update after each folder / file. Sometimes it keeps giving me the Recycle Bin's icon at different folders.
[Code]...
I have seen lots of examples with a treeview to list folders then display the folders context in a listview.
But what id like is a checked treeview, that not only displays the folder list, but the actually folder contents as well.
I have used the TreeView and populated the list using the following code:
m_strStation = cboStation.SelectedItem
For Each strDir As IO.DirectoryInfo In New IO.DirectoryInfo(m_strPath & m_strStation).GetDirectories()
trvFolders.Nodes.Add(strDir.Name)
Next
The TreeView populates and every folder is visible, however the folder names consist of:Place #. Name the problem I am having is that the number range is 1 - 16 and the order in which the folders are being displayed is 1, 10, 11, ..., 15, 16, 2, 3, ..., 8, 9 I am looking for the folders to be listed in true numerical order e.g. 1, 2, 3, ..., 14, 15, 16
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:
[Code]...
The code is total crap... causes my app to hang. Pretty sure infinite recursion is the cause.
I am using the SHGetFileInfo function to get the name of folders etc. The reason that I use it, is because it also has to get the name when copying a drive, so it returns "Local Disk (C:)" instead of "C:".This worked, up until recently, I cannot remember what I changed! Suddenly, it's always missing the first 4 letters! Like, "Local Disk (C:)" becomes "l Disk (C:)".
I'm on Windows 7, and it works just fine on Windows XP. Here's my
<DllImport("shell32.dll")> Private Function SHGetFileInfo(ByVal pszPath As String, ByVal dwFileAttributes As UInteger, ByRef psfi As SHFILEINFO, ByVal cbSizeFileInfo As UInteger, ByVal uFlags As UInteger) As IntPtr
End Function

I also made a test project with the EXACT same code, and it did work...
I would like to use a treeview control to display related data as Folders(Level0), Projects(Level1), Drawings(Level2). So far I don't have a problem reading data from a database, creating classes to hold the data and displaying the tree from the class data. I have created (3) contect menu strips, one for each level of the tree to perform various tasks. Each menu has an ADD option to either add a folder, add a project or add a drawing.My problem is as follows...After I add the node, in the correct location, I would like to have it set in the BeginEdit mode.
Dim oNode As New TreeNode
oNode = TreeView1.SelectedNode.Nodes.Add(sNextID, "New Project")
oNode.ImageIndex = 1
TreeView1.Refresh()
[code]....
After this code runs, the node.Text changes back to "New Project". As you can see, I added a few debug.print statements to try to see what is going on. It really blew my mind to see that the entire tree printed in the immediate window.I have already created a work around for this, but is isn't really the way I'd like to see the program run.

View 1 Repliesi posted about how to transfer file and i found a thread explains it with sample. Now how am i able to display it in a form the file transfer, the icon the name and size. And the user can click it .
View 4 RepliesHere's the code that I use to extract the icon size that I want:
Dim i As Icon = My.Resources.Spectrum
Using i2 As New Icon(i, New Size(256, 256))
Me.PictureBox1.Image = i2.ToBitmap
End Using
This works from 16x16 up to 128x128 but for 256x256 it extracts the 128x128 icon. I tried 0x0, because I seem to remember that that is how the large size is stored in the meta data, but that didn't work either.
ok so i have this already done:
Dim x, y As Integer
x = 0
y = 0

I am trying to populate a TreeView control with all of the folders and files in a specific directory.I have a folder C:Temp and under this folder it has 3 more folders C:Temp1, Temp2, Temp3. Under each of these folders are files.How can I populate a treeview control recursively to do this? I have been working on it, but my code is extremely wrong and I couldnt find anything that helped by searching.

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 RepliesThis is somewhat of a multi part question, let me start off by explaining what I'm trying to do. I have an organized folder system with data files in them. Each folder has a set structure to their naming, and can contain sub folders and files. It will be a jagged directory system. I'm trying to import their structure into a TreeView. I have the workings of a recursive system that adds all files and folders into a ViewTree, however they aren't organized by parent/child.
So I get this...
-C:Temp
-C:TempData
-C:Tempfile1.txt
-C:Tempfile2.txt
-C:TempDatafile3.txt
-C:TempDatafile4.txt
etc........
How would I go about parsing the directory paths, and include them into a parent/child relationship... looking like this
+Temp
--file1.txt
--file2.txt
-+Data
---file3.txt
---file4.txt
Also I when the line item is selected, I need to know which file is selected so I can use it's full path to call up data (using an API) based upon the it's full root path.

I'm loading a folder (path), which contains folders and files, in a treeview according the combobox-text.
When I load the app. the combobox is filled with the paths. I'm using the SelectedIndexChanged to load the treeview. Everything works.
The issue is that it also starts to load the paths the treeview also gets loaded (slow), but it should only load when I select an item in the combobox.
I tried comboboxselectedtextchanged etc, but without any luck. Besides that loading the files and folders is slow.
Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0

View 3 RepliesI have a TreeView.I am building the nodes within a For/Each loop.I then add icons to each node from an ImageList control.The icons load properly. However I am noticing that when I click onto the nodes, after the TreeView is built, the selected node defaults to another image. It seems to always default to the image which has the index of whatever is set in the Properties Windows for the Control for ImageIndex.So assume that the ImageIndex is set to 0 in the Properties Window.If I add ImageIndex 1 to the node at run time (See Below), ImageIndex 1 show up but once I click onto this node the icons switches to ImageIndex 0.[code]
