Track Webpage Downloading Progress?
May 2, 2012
I'm using this piece of code for VB.NET to download the text from a website:
Dim Str As System.IO.Stream
Dim srRead As System.IO.StreamReader
Dim req As System.Net.WebRequest = System.Net.WebRequest.Create("http://www.example.com/file.txt")
[code]....
It is just a text file, and is rather small, so it downloads really quickly. But I do believe that in the future the file will become considerably large. Is there a way to track the downloading progress from the above method?

I'm trying to make a program where you can keep track of your progress through various projects your doing. I'd like to have it so they can add a new project via the text box/button and then when they click on that project from a listbox or something(still trying to figure out the best way) it shows the notes they have typed etc. I know how to make it so its saved when they exit and all that good stuff but I'm not sure how I would do everything else.

I am trying to track the progress of a meter in a flash window and click when it reaches a certain point. I am currently using getpixel() to "watch" a single pixel and when it changes to green, perfrom a click. Problem is i have to "watch a pixel" about 20 pixels left of the intended target and then click. Reason, when the program has realized the pixel is green, it clicks, but this has not been as accurate as needed. Sometimes it clicks to soon and sometimes it clicks to late.
Before you suggest using DIBS, i didn't use it because i am loading a 1x1 screenshot and watching that pixel in a loop. I figured since i was continously loading a new bitmap via getpixel that dibs would not be any quicker. The way i read dibs is that if i was loading a bunch of pixels it would be faster because it goes ahead and loads into an array.Is there another way to monitor a meter in a flash window?

I am trying to use a power meter to track the progress of my program; this will be for my use only and will be removed later. I would also like to display the percentage run in the meter. I already know what the start and end points will be for the meter. What do I need to search for? I have been looking and haven�t been able to find anything that suits my needs yet. I am running VB 2005.

I am attempting to make a "Downloader" which would download a file from the internet and save it to a local drive. However some challenges come into play, I would like the downloader to show progress. I am aware of many posts on msdn that give code on how to do this but, I would like to learn the code rather than just copy and pasting it.url...

What I am wanting to do is create a program that will load up a page (it is password protected) and get the links out of any files that I need to download. The green text is the text that contains the link and will be repeated for every file.One little thing is that there are multiple pages that are accessed through JavaScript with the code highlighted in red. So, I also need to step through the pages and get a list of all files on subsequent pages.
Everytime I run this program, it will get a list of all files and only download the ones that aren't already downloaded. However, I have never done this before and was wondering what I need.I have accessed the source of pages and parsed it for things like links before, but not sure if that is the optimal way or if there is some other way to handle this particular situation easier, especially since I have multiple pages to deal with and JavaScript.

How do you access a web page's source code without downloading the file? i.e., downloading a .php file generally wouldn't work - I want to access the code that it would return if I was using a browser.

For some odd reason, when I download text files, the HTML of the web page is being appended to the text! All other file types work fine!Here's the code that's doing the download:
Public Sub DownloadBlob(ByVal Blob As Byte(), ByVal FileName As String, ByVal Response As HttpResponse)
Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", FileName.Replace(" ", "_")))
Response.ContentType = String.Format("application/{0}", Path.GetExtension(FileName).Substring(1))
Response.BinaryWrite(Blob)
End Sub

The following code is giving me a headache. As you can see there are message boxes in there for a quick debugging tool. It displays the messagebox "Still looping" once, and then shows the form. No other code runs. Doesnt matter what I put it it just doesnt run. I can't see a problem anywhere....

I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

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())
