View 1 RepliesI'm writing a web browser in Visual Basic 2010 Express and I would like to add a progress bar, it all appears to work when I run the program and navigate to a website, but usually (about halfway through) it reaches an error where the progress is either above the maximum or below the minimum.
Here's the code:
Private Sub WebBrowser1_ProgressChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged
ProgressBar1.Minimum = 0
ProgressBar1.Maximum = e.MaximumProgress
ProgressBar1.Value = e.CurrentProgress
[Code] .....
I have a webbrowser control, and a progressbar1.I can set an event to be fired off when i navigate, but when its done, i dont know how to clear the data.Also, the progress bar, dosent really follow how much procesing is left on the web page.
View 6 RepliesI'm having a problem with the progress bar. I have set a progress bar to show the loading progress of a webBrowser, and I have set the webBrowser to keep reloading automatically. The problem is that the progress bar only shows the value during the first time the WebBrowser loads, and it then remains at 0 from the 2nd time its reloading and above.

'Update Progress Bar
[code].....
I have a progress bar on a Windows Form which displays the number of records as they are retrieved from the database.The problem I'm having is that the entire Form.Load() method seems to run prior to the form being displayed, which means all my code updating the progress bar is gone to waste.

View 9 RepliesI need a progress bar to show the download progress of a file from the webbrowser control.
I want the default popout download window to not show and to show the progress bar
somewhere else, and show the time remaining. Basicaly what I want is for my info of the
window that shows download progress and info to show on the default window of my program.
If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
2 questions:
1. How, programmatically, can you tell if a progress bar is at its max?
2. If it's at it's max, how can you reset it to zero?
currently i am using a threadpool that contain a number of thread. This number of thread can be different everytime, sometimes 5, sometimes 10, sometimes 15 and so on (multiple of 5). So now i have it working good by using for loop to queue the thread into threadpool. Now the problems is i do not know how to make the progress bar depending on my threadpool. I want my progress bar to complete only when all the thread are done. After searching google, i found that maybe it can be solve by using AutoResetEvent(false), but after i apply to my program, it still did not work, my program hang at xEvent.WaitOne() method and didnt proceed further, anyone can explain to me how to solve the problem? Or got any other ways? For your information, only 5 threads can be running at the same time as the requirement state so (so i set the setmaxthread to 5 already).
View 1 Repliesi have a form that takes a long time to open (because of the volume of data and the devexpress scheduler controls on it). I would like to pop up a progress bar (embedded in a form) to show until the form loads and is finished loading.i added two public methods in the My.MyApplication class...the form with the progress bar shows, but is stuck and doesn't animate.i figure that i need to open this form in a separate thread, but have done no work with multithreading.[code]is there an easy way to make this form always open in a different thread so that it will animate and show my "loading.."
View 3 RepliesI have 1 form with the progress bar and 4 buttons with the following code.I would like to create another form that shows the same progress bar with the same progress.Here's my code for progress bar....form load code is:[code]....
how do i get that progress bar to be show in another form?
If form2.ProgressBar1.Value < 100 Then
ProgressBar1.Value += 20
End If
Im having some trouble with my progress bars in VB.Net. I am currently making a 2d game for a college assignment. The problem is i have one for health and one for reloading the reload bar works fine but when i try to code the health bar i think it conflicts with the other Progress bar [Code]
View 3 RepliesI am wondering how do I update a Progress Bar that resides in Form1 (for example) from a newly created class called from the Button in Form1. I have read several tutorial about backgroundworker. Most of the googled tutorials have their "long process code" in the do_work event. I have tried them and got it working from within the form itself.
However, there are 2 parts (long process) in which I wish to incorporate the updating of the progress bar; First one being a long sub routine that is in the main form (Form1). The second one is another long processing function that resides in a class. It is the second one that is giving the problem as I have no idea how to call the backgroundworker.reportProgress() to update the UI.
Here is the sample flowchart that I have created for the second long processing function:
I wish to insert a new instruction that says "Update the Progress bar that is in Form1" after the current instruction "Store the member into a collection".
I want to make an app that gets the progress bar to 'pulse'
My code doesnt seem to work though!?!?!
Public Class Form1
Dim Value
Dim NoValue = "Add"

I am new to VS 2008.. It is possible to change the progress bar loading color (green) to other color? How to change it?
View 3 Repliesso what I want to do should be pretty simple. I've been following the examples found here Using the BackgroundWorker Component - VBForums . I've been successful, but I'm not smart enough to put it in my project.
What I'd like to happen is this
1. I hit a button to load data from a dataset....
2. have a progress bar show until this action is complete.
The main problem is that I can't figure out how to tie the "progress bar" to the action of "pulling the dataset"
I'm sure this is a crazy question for you all, but hey...
Would I put all of the coding in the button_Click sub?
I'm using vs2008 programming in vb.net. I'm currently working on a project that reads miscellaneous text files and imports data into a sql database accordingly (Reads line, imports, loops until finished). There are 75k-150k imports to do. I tested it out the other day before using a progress bar, it takes about 5-10 minutes and works fine.
The issue I have is that while importing, if you click anywhere on the form, it will say not responding and will continue to import, but users using the program might be mistaken and think the program has locked up. I thought a progress bar would solve this, since it is responding back while the imports are going on in the background. However, the progress bar works, but as soon as you click anything on the form, it again says not responding and the progress bar stops moving (the imports will complete however). How can I isolate this import process so it can do this in the background, but will not affect the rest of the program?
I have 1 form with the progress bar and 4 buttons with the following code. I would like to create another form that shows the same progress bar with the same progress. [Code]
View 1 RepliesIs there anyway to complete a progress bar just by going ProgressBar1.Value = 100 when you want it to finish. I have a button which starts a countdown, I need the progress bar to complete when countdown reaches 0. Ive already used the step version, but when I want to alert the length of the countdown, the progress bar finishes too late or too early.

View 1 RepliesI was looking for a solution to run a lengthy job (looking for files on the fixed drives) withouth freezing the UI, and saw that using a BackGroundWorker control is the recommended solution.
Problem is, I don't see its ProgressChange event being triggered:

I had some trouble a while back with my progress bars exceeding their maximum sizes. I though I had fixed the problem but obviously I was wrong every time the maximum size is exeeded the application enteres debugging mode .... this is really frustrating as the progress bars are a major factor in the game...
What I have is one progress bar which is linked to a clock the clock which ticks up to 1:30 and the game then ends. I also have another progress bar showing the health of the shooter.
I have a series of collision codes set up which are linked to these progress bars, that add to them and take from them.
'Heath pick up collision code...
If (HPU.Top + HPU.Height >= Shooter.Top) And (HPU.Top <= Shooter.Top + Shooter.Height) And (HPU.Left + HPU.Width >= Shooter.Left) And (HPU.Left <= Shooter.Left + Shooter.Width) And HPU.Visible = True Then

I have tried re-routing the overload so that if it cannot add no more to the progress bars it adds nothing to them.
I'm looking to be able to open a .txt file (with sites 1 per line) and visit all of those sites silently while moving a progress bar.
