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.
I have a treeview in my form which should be populated with all dirves, folders and files on your computer. i found a couple of examples here on vbforums and other sites on the internet and put it together in to the code listed below.
Main_Form.vb Imports System.IO Public Class Main_Form
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.
This 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.
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 currently have a procedure that stores the Level, Parent.Level, and Text properties of each TreeNode in a TreeView control in a DataTable.I can't seem to come up with the logic to load this data back into the TreeView from scratch, though.
Below is what i currently have in place which does not work.
Private Sub LoadTree(ByVal table As Data.DataTable) treeBilling.Nodes.Clear() For Each row As Data.DataRow In table.Rows
I made an uninstaller which uninstalls certain application. However this application have lots of read-only files and folders and my uninstaller isn't able to remove any of them.
Here's the uninstaller code that I have: Imports System.IO Dim path As String Dim tempstring As String Dim totalbytes As Long [Code] ......
My program actually downloads a zip file then extracts it onto their desktop. But I need an uninstall feature for it, which is basically deleting multiple folders and containing files. How can I do this in vb.net?
I need help with file enumeration. I'm trying to create a program that can list files, folders and sub folders locations in a log file for diagnostic purposes. After it searches it can open notepad and display the results. The problem I'm having is that I'm a beginner and not familiar with file enumeration.
(Currently using VB.NET 2010 Express) I'm trying to make a program, the main of which is file transfer. I'm trying to create a program that will keep files and folders synchronized across multiple client computers. I'm using a File system watcher to trigger events, and Using a simple System.Net.Sockets UDP client transfer (found via google) to transfer commands between it and itself on other computers.
Here's that code (this just sends from one textbox to another over the internet) Imports System.Net.Sockets Imports System.Net Imports System.Text Dim udpClient As New UdpClient(1024) Dim RemoteIpEndPoint As New IPEndPoint(IPAddress.Any, 0) [Code] .....
By this method, I can rename, move, or delete files. I want to implement file transfer, so that whenever a new file is created, or updated, my program will automatically transfer the file to the other computers and update them there.
I'm loading 3 comboboxes and a treeview with values, from a remote database when the app starts. As we all know the app freezes until it's done loading. I want to speed things up.
Dim _thread As Thread _thread = New Thread(AddressOf test_loading) _thread.Start()
[code]....
When I execute this code I get the following error:
mycomboboc.Items.Add(reader.Item("columnname").ToString)Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.
I use to code looooong (98ish)ago in Visual Basic 5 but I haven't touched it since 2000. Well now im back and I must say i quite rusty!!Here is what I need help with. I've successfully created a save command for a Comma-Delimited txt file. My problems come from when I try to load the file, I can load the first line just fine. But multiple lines are going to be an issue. I don't quite understand how to tell the program to go through each line.[code]
call form1.axshockwaveflash1.loadmovie(1, application.stratuppath + ("swfsStart.swf")) but when i publish the trainer, and open it through either the clickonce application, or the setup, it can't find the swfs folder to get the .swf files. Therefor the trainer will not work.
Have built a project and associated it with a Setup&Deployment Project. The S&D project needs to contain 2 main folders (under User's Desktop) with various formats of files (xmls, txts, dlls) inside them and several subfolders. How can i copy/import these 2 folders and there sub-files/folders into my s&d project?
When adding them in the usual way, they are copied and defined a source path onto the current pc. You can understand what errors this might create when an another targeted pc does not contain those files to the exact location. Is there any way to copy them locally or somehow import them?
I'm having a treeview loaded with all the files and subfolders of a path. Each node is getting the filepath as tag. Once I have dragged a node (file/folder) I need to move the file(s)/(sub)folder to the new directory. Each file(s)/(sub)folder needs to get a new tag
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
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.
I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.
