Display Progress Of Loading A Text File Into A Listbox With ProgressBar
May 15, 2009
I was wondering if this was possible, if so can you point me in the right direction? "Display the progress of loading a txt file into a listbox with ProgressBar".I am basically loading a file (blah.txt) which contains several strings each on their own line:[code]I would like to display the progress of the listbox loading within a progress bar.
im working on the project and loading 10 MB text file to richtextbox, but problem is my application freezing during that time. Can anyone post the solution for progressbar during the file is loading?
I am trying to read a text file into a text box, and show the progress bar loading. Sometimes if the text file is big, i don't know when it will finish reading it. This is basically the code i use to read a text file, but i don't know how to show the progress bar.
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.
I am trying to add Images using open file dialog and folder browse dialog and populating the image list to listbox.While adding these Images I need to show the progress bar for every image it loads.
I am trying to get that but when the value of the progress bar say something around 25 0r 40 it is stopping at that point but I need to show the progress bar until it completes the 100% and then populates the Image list.
Here is my code:
Private Sub AddImages_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddImages.Click If Not Directory.Exists(Application.StartupPath + "Backup") = True Then
I need to load the contents of a text file (itemInfo.txt) into a list box
Public Class MainForm Private path As String = "L:Visual BasicSequentialHW" Private Sub MainForm_Load(ByVal sender As Object, ByVal e As System.EventArgs)
The duplicates need to stay as they are in the text file. I just want the duplicates deleted from the listbox when viewed. How would I do that? Say there are two orders made by the same user. I only want the user to show up once in the listbox...
I am having trouble getting the Fiction.txt File to display. I don't receive any errors the program just does not seem to react. I think the problem lies in the creation of Fiction.txt.[code]....
I got a program that starts a batch file into a textbox and makes backups of my database things, I would like to add a progressbar to my program to see while the progress is running, here is my code, but its not working good at all, I mean, the progressbar one works, but it dont update with the files copied, etc...

I'm trying to load the contents of text files into a listbox. It loads the file fine but adds an extra character at the end. I have a feeling it has something to do with my Split command but I'm not sure how to fix it.

Dim ofd As New OpenFileDialog ofd.Filter = "Text files (*.txt)|*.txt" Dim result As DialogResult = ofd.ShowDialog
how can i attach a progress bar to a crystal report progress control, my code extracts the data from the SQL Server database and displays it on a crystal report. all this process may take long time as the data size may be large or joins may take time, so how can i display this progress in a progress bar. How to attach hidden processes to the progressbar.
I want to change the color of the progress that fills the progressbar, its default is green but i would like to change it to red or any other color if possible.
I would just like to know if there is a way to integrate a progressbar that shows the progress of the process? I mean when process.Start is activated, that's when the progressbar starts to load until and stops only when process.HasExited.

I'm creating a program that can run a large audio file (*.wav) in a seperate thread using the background worker, the only problem I'm having is trying to report the progress using a progress bar. When I try to report progress nothing happens. here is the code below:

I'm writing a program that retrieves certain lines from a textfile. This textfile is rather large, so is it possible to have a progressbar that shows the progress when it retrieves?
Ok here we go again, im a complete beginner to coding and have started with visual studio 2008 using the .net/vb libraries, as my first project i went with an emulation application, and it went great:So now i think its time to move onto a little more advanced tech's, so i added in a combo box and i want to change how my code works, and this is where my troubles are.To start of with the combo box, i have it added to my winform and have 3 items on it 'Action' 'RPG' and 'Sim' and i have made 3 .txt files in the projects root folder with the same names. What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged If (ComboBox1.SelectedItem = "RPG") Then
I am using file.readalllines to read the file into a string, then using listbox.items.addrange and splitting by vbcrlf to insert the items. Is there a way to reduce the lag it causes for loading huge lists?
I have a form let's call it Form1 that calls another form(Form2) Form2 to has a bit a code that needs to load in the LOAD_EVENT and takes about 4 seconds.

im making a web browser which is intertwind in a project, but i cant get the progress bar to display the current percent of a page that is loaded, i want to have 10 segments, each standing for 10% of the total page loaded. So say a page is loaded 67%, 6 out of 10 of the segments will be shown.
on page load i have a listbox which gets populated with the subfolders of a folder, im trying to have it so a progress bar fills as each item is added but im not having any luck with remembering how to do this And googles not been to helpfull.Heres my code so far:
vb Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ProgressBar2.Maximum = ListBox1.Items.Count ProgressBar2.Minimum = 0 ProgressBar2.Value = 0
