View 2 RepliesI have a weird bug with webclient. I made an app a while ago which uses webclient to download a small thumbnail image.. and I rememeber when I first made it, the first time webclient was used to download the image it always took 15 sec+ to download it, but after the first it always downloaded quickly (in like 1 sec) .. but then the problem went away for me and it always downloaded fine.but now someone else who uses my app is having the slow image download problem apparently around 50% of the time it downloads the thumbnail images. so does anyone know what might be causing this? As I said, I don't have the problem any more on my comp - but I don't know why :s

I'm using this code to download a file from ftp server,it works fine but progress bar doesn.'t update, WClient_ProgressChanged is raised only at 100% downloaded.Download time isn't so fast is about 27 seconds for a 17Mb file.
I have incorporated an updater into my program but I want a progress bar to show the download. I have created a new form with the progress bar on it.

This is the Download file code which is 100% working when i will give directlink of file
And in this case progress bar is not working anymore and program hangs too let me know what is the problem with above code and how i will correct it
Ok i have a progress bar that increases when a download starts to finish. The once its compleate the next part of the script starts.
After all the script has finished, around 30 seconds. It starts the full process again but atm it wont start again as the progressbar is still complete.
I have tryed adding
ProgressBar1.Value = 0
To the end of the script to set its value back befor the script starts again but that dont work either :/
How would i get the progress bar to go back to its orginal state so that it can start all over again.

I hve threaded ftp download, and that thread reports it's progressto another form (to progress bar). Now, when thread downloads, progress of thread is much slower than actual download is, so for instance: all files get downloaded, but the progressbar is at 50% or even less. Is there a way to track the progress of actual FTP download.

View 1 RepliesWe recently started playing with a vb.net 2008 WebClient on a Windows 7/64 workstation to download files from a web site to the local machine.It works except that we cannot detect if the URL is invalid. It doesn't throw an error. If we use Async it does trigger the Download Complete event but there was no file since the URL was incorrect.Is there a way to detect an incorrect URL?I also noticed that the events does not give you either the URL or the file?

The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.

I'm trying to use a java servlet in a 3rd party tool's web interface (CA service desk) to invoke it's download file functionality using a webclient in vb.net. The trouble is the text stream from response is markup and not the acutual text file stream.
It's like the page is redirecting to another page which actually presents the file for downloading. I have no idea what the redirected page URL is.
Is there a way I can process this redirected page in order to get at the download using a system.net.webclient?

How come I don't get a "Done!" when it's finished downloading the file? (The file is only ~100kb.)
[Code] How i think that this should work: 1. Getting the size of the file that we want to download and updating the progressbar max value to that 2. Downloading the file and updating the progress-bar based on how much data its downloaded.
