Speed Up Directory TreeView Part 2?

May 30, 2009

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].....

Speed Up Directory Tree View?

Apr 21, 2009

I am loading the directories from my C drive into a treeview using the code below. It takes forever due to the number of folders. Is it possible to have this only populate down 1 level and then use a NodeMouseClick Event to drill down further, in the same treeView, if the user desires to do so? How would I amend this code to do this?

File Size Affect Speed Of Directory Listing?

May 7, 2012

I have an app that reads a directory to get the filenames in a directory for each File in Directory(process file) next file. I want to know if the file size makes a difference to the time it takes to get the filenames.eg if a folder contains 10,000 photos of 1 megapixel and another has a folder of 10,000 photos of 8 megapixels will it take the same time.

C+ Speed Differential - Search A Directory Of 12000 Blocks (512 Byte Records) In .46 Seconds?

Sep 4, 2011

Using a C+ DLL i can search a directory of 12000 blocks (512 byte records) in .46 seconds. That's moving.I can search it with the following code:

Imports System.IO.DirectoryInfo

Imports Microsoft.VisualBasic.FileIO

Imports System.Globalization[code]....

My question is, that's pretty fast. Why the enormous speed differential between C+ and VB? "Becase VB is managed code", doesn't really answer the question.

Add Child Nodes To A Treeview From A Directory Path?

Jun 9, 2009

I have a treeview, a button and a textbox. When you click button1 a folderbrowserdialog opens and after choosing the folder the path to the folder and anything in it is show in the textbox and with this

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim sDirs() As String

[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.

Displaying Directory Tree Structure In TreeView?

Feb 26, 2010

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?

Multi Form / Part Application Need To Make Part Protable For Transfer

Feb 22, 2011

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts

1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers

2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly

3. the config files

anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.
