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 4 Repliescurrently 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.."

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 1 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?

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 3 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.

View 1 RepliesI have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

In the app I'm currently making, I have two progress bars. One for current task being committed and the other is for overall progress.During runtime, I calculate how many tasks are being run and set that as the maximum. As each task completes, the progress bar is incremented by one.
I want the current task progress bar to show the progress of the current task. Some tasks can take a few minutes to complete so that progress bar works great. But, if the task is super quick, like editing registry keys, I see no progress at all.When I edit the registry, it basically goes like this:
'Edit Key
'x
'x
'x
ProgressBar1.PerformStep()[code].....
It completes so quickly that I never see the bar even move.I also have each task report its name into a label and it skips ahead so quickly that I only see the first task name and the last.Is there any way to make this do a better job at reporting the progress?
I came across a problem in my program it takes too long to calculate the values needed (about 10 sec) .But thats not the problem you don't know when the program is working or not, as it just locks up until its finshed and I view that as a problem.
I need to be able to show the progress of this .I looked at using background Workers but I get exception "Object reference not set to an instance" I believe this is because the background worker cannot write values or something ,As it works will a normal handler.
