I am making a little program witch get information from the web. Now i got some complains from people who are behind proxys. So my question is: Is there a way to get the proxy settings from IE, and let the WebClient use them?

I'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)
request.Proxy = curProxy
[Code] .....
Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.
I just noticed that if I use WebClient to download an image in my VB.NET application, it will use a proxy that I have set in internet explorer (under connections->lan settings)! I don't want this to happen.. Is there a way I can use WebClient in my application but stop it from using the proxy? (but would be nice to keep the proxy set in internet explorer).

View 5 RepliesI need to create an ASP.NET application to access a URL, when this application is live it is able to access the feed URL correctly as the clientaccesspolicy.xml and crossdomain.xml are on the server but only allow non-localhost connections so the debug version won't connect. How do I create a file, so this kind of link:
[URL]
Can be used to pass-through to the RSS feed service live URL like:
[URL]
So that I can develop my application via localhost as I can add a clientaccesspolicy and crossdomain file to this application so my Silverlight Application can access the live RSS service, while being developed without having to deploy it online every time I need to see what the application will look like.
A dummy RSS file is not suitable as I need to see various "Items" from the Feed.
I'm making a application to use in college to retrieve my calendar and other things in VB.NET. But my college uses a proxy so when I connect my laptop I need to change the internet settings in my web browser to view web pages. how I would send requests via a proxy server in VB.NET? Or is there a piece of software that I can download which tunnels all connections or is there a setting in win7 does this?

View 2 Repliesi'm using WebClient in VB.NET to make requests. I add the headers using WebClient.Headers.Add() in the order I want the headers sent. However when I packet sniff the requests it makes I can see that the headers are sent in totally the wrong order. Does anyone know if there's a way of setting the order the headers are sent?
View 5 RepliesI've been testing using WebClient.DownloadString and sometimes I encounter an error: "The remote server returned an error: (403) Forbidden". It is based upon which url I use. For instance, this works:

Try
strResult = wc.DownloadString("http:/ Obama pages always fails.

Ive searched 12 pages of google and on these forums and find nothing helpful.
ive made a nice program that grabs proxys from a site and adds them to a list box in the format of iport. It grabs around 3k http proxys.
Ive also added another listbox and a button. What i need is to click the button and it will check the proxys from listbox1 and add working proxys to listbox2 but i have no idea how to do this.
I have searched and searched for days now and just cant find one, this project has been on hold for around 2 weeks as i just cant figure it out :[code...]
Is it possible to change/set my Internet Explorer proxy setting in VB.NET application? For example, change the proxy server IP.
If so, do I call and add the MS Web Browser into my toolbox, and add the object on my form to do it, or I'm totally wrong, there are something else I should take care of.
i am using the Webclient and Streamreader in Visual basic 2008 to retrieve data from the web. I access Yahoo and download stock information this all works well except for one area. All the indices symbols on Yahoo start with a circumflex character ^ so for example, the Dow Jones Index code is ^FTSE. When I include the ^ in the URI string sent via the Webclient it does not send the ^ it sends the code for ^ instead which Yahoo sees as %5E. Having made some tests is seems that certain characters do not get converted to their hex code and some do. A * gets sent just fine but a % also gets sent as its code 25.If I manually enter this from my browser it works just fine.
View 2 RepliesI've just switched my code over that downloads data as bytes to use a WebClient. I add a header saying I will accept GZip and the site I'm downloading from sends me the data compressed. The problem is, how can I check to make sure it is compressed data before attempting to decompress it? It was much simpler when I was using a Web Request to check the response headers, but I'm having a little trouble checking the reponse headers with a WebClient. Does anybody out there accept compression with a WebClient?
View 1 RepliesI'm looking for a way to fill in various website details using a HttpWebRequest/WebClient. I can manage it quite easily using an invisible WebBrowser control, by manipulating the HtmlDocument, but for some reason I just can't quite grasp the way I would do it with a HttpWebRequest/WebClient. I've heard both of these can potentially submit info using the UploadData functionality etc, but I'm missing specificsI've done a lot of searching on google just for a basic example to get me started, but the only one that LOOKED informative was written entirely in German.Take, for example, this website. Let's just say I wanted to automate filling in my username and password into their respective boxes and then pressing the "submit" button. How would I start going about this, and how do I get the resulting page? (I'm assuming cookies that the page creates will keep your next webrequest going)
View 9 RepliesI've been using an invisible WebBrowser control to submit a form on my server, but I'd like to use System.Net.WebClient() to accomplish this so I don't have the control hanging around on my form.I need to get the page, fill out the username and password fields, and click the submit button. This was done easily enough with the WebBrowser control, but I can't find any examples using System.Net.WebClient().

View 1 RepliesI can download the files I want. However, the client has insisted on creating different folders which will contain the version number. So the name of the folders would be something like this: 1.0.1, 1.0.2, 1.0.3, etc.So the files will be contained in the latest version in this case folder 1.0.3. However, how can my web client detect which is the latest one?
View 3 RepliesI'm having trouble using the webclient to download a file. This same code works in another app that I'm using, but when downloading the second file, I get an exception saying that there are illegal characters in the path.The second item that it is having troubledownloading's filename is "Filename.exe.manifest". The RemoteUri is the download link, item is the name of the file. When I print out the path that it is downloading from and the path that it is downloading to, both are correct. I can type the address in the browser and it downloads fine. (The problem file is not exename)
For Each item As String In files
If item = exename Then
If My.Computer.FileSystem.FileExists(Forms.Application.StartupPath & "" & item & ".new")

I 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
