I start making program that will burn CD/DVDs, and everything is okay. I found way to burn with IMAPI2 API, but now I have problem: I can't get progress bar of that burning.
Here is code:

I'm trying to understand how to route the events of my IMAPI2 burning progress but not sure how to do it. I've coded event handling before, but just not familiar with the IMAPI2 library so having some trouble.
This is their sample code in c#:

i want to write a small app which enables the user to burn some files on cd/dvd. Something like:
- Make an export from related DB Tables with informations
- Collect customers informations
- zip everything
-burn on cd (its a settlement related tool)
I am trying to implement a BGW and want to report progress to a progress bar for my TextFieldParser program, sometimes if your opening very large files it takes a while and I would like the user to be able to see the progress and have some interaction so they know the program is still running I am a little hung up on what to in the reportprogress
I have:
worker.ReportProgress(0, myReader.ReadFields())
and its not doing anything, I didnt expect it too since ReadFields is an array
parser
Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim worker As System.ComponentModel.BackgroundWorker = DirectCast(sender, System.ComponentModel.BackgroundWorker)

Where can I get some good advice on using the IMAPI2.dll. Pickens are very slim and limited in VB 2008 Pro, and if there is an abundance, I just haven't came across it yet. I will follow-up on all links. My OS is Vista, and everything is up to date, except me.

The frmMain allows the user to run any one of the three modules individually or all together in a single process (basically, runs the one after the other until done).

View 3 RepliesI am implementing IMAPI2 into my vb.net project but ran into a wall. I am getting the message Unable to cast object of type 'IMAPI2FS.FsiStreamClass' to type 'IMAPI2.IStream' when trying to start the burn. I googled around and found this is something that microsoft hasn't fixed.. which basically renders IMAPI2 useless in vb.net.
I found a post on codeproject.com by eric hadden who combined the IMAPI2.dll and IMAPI2fs.dll into an c# interop file. I also see the IBURN interop in microsoft SDK samples. I'd like to use either, but it's in c# and I'm using vb express. Does anyone know a way to get the interop into visual basic or a way around "Unable to cast object of type 'IMAPI2FS.FsiStreamClass' to type 'IMAPI2.IStream'"?
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.

View 10 RepliesI have two forms, when the user selects a button, the second form opens and an external executable begins an automated process. The point of the second form, is to only show the current progress of the automated tasks and closes when those tasks are completed.How would I use a progress bar to show the current progress of an action on a different form without knowing how long it will take?

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.

I'm trying to draw text on the progressbar. This code below works, but when the progress bar re-paints itself the text disappears.
ProgressBar1.CreateGraphics().DrawString(Vaule & "%", New Font("Arial", CSng(8.25), FontStyle.Regular), Brushes.Black, New PointF(ProgressBar1.Width / 2 - 10, ProgressBar1.Height / 2 - 7))
jmcilhinney suggested i look into the PaintEventHandler.
I read the MSDN documents, but they used PictureBox(). I made this code below, but no luck.

Been taking a programming class in school for the last year and we haven't really done anything with a progress bar so I was curious to see what I can do with it. I found some basic code to see how it worked and I get it.[code]However, instead of having a fixed time, I want the maximum to represent the time it takes for something to be done whether it be loading a new form, searching for something, etc. I don't know if that made sense, but basically I want the progress bar to react accordingly to the time it takes to do something.For example, in this little test project I just want the progress bar to represent the time it takes to load form2. I believe you'd have to change the maximum. However, I don't know how to get Form2's load time to be able to put it in the progress bar's maximum.

View 5 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.

I was just thinking is there a method i can use. For example if the maximum value is 200 and the current value is 97. or i have to use math to get the percentage.
View 10 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).
