I'm trying to download a simple text file from a web server. It's easily accessible from the web browser and I can download it from the web browser. However, whenever I use a WebClient to download the file, I get a 403 Access Forbidden Error! I'm not sure what I'm supposed to do. I haven't come across this kind of error in programming before and I'm not sure what I'm supposed to do to get around it.

I'm trying to download multiple files based on what a user has selected on a formI have multiple checkboxes in place, so If a user would select Checkboxes 1,3,4 I would want the webclient to download files 1.txt, 3.txt, 4.txt.The WebClient method is causing a "WebClient does not support concurrent I/O operations." error.
If chk1.Checked Then
WC.DownloadFileAsync(New Uri("http://www.google.com/1.txt), Path.Combine(DataSource & strDirectory, "1.txt"))

the program per se does a lot of "parsing" of htmls, eliminating the information not needed and also download automatically certain images ( Satellite specially.. ) most of these images are... sort of hidding inside the html ( thus the parsing.)[code]...
I'm getting the 403 Forbidden error while running a VS 2010 in debug mode. It gives me this error as it tries to read thru an XML File. See attachment. This is a web app and it's reading an XML file that retrieves the DB/Server information. It's not the Web.Config file but just a regular xml file. This file is read by every application in our system. Not sure why it suddenly started doing this. I've created the virtual directory on our IIS Server and set permissions on the C:inetpubwwwrootAppName directory of my C: drive where the app resides.

I'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.

Syntax error (missing operator) in query expression '''system time'''.this is the error that appears
this is my code:

the fields in the tables are all text fields.is there any way to fix this error? perhaps it is in my query but i really cant find a solution.is there an alternative to get what i want my program to do?it is basically entering an ID number and finding the record with the same idnumber and putting the system time on the timein field for that record.
I'm automating downloads. I was getting this error quite a bit using Webbrowser to navigate to a PDF (various PDFs at various websites). In other words the PDF was already on display in the browser when I called WebClient.DownloadToFile. I got a LOT better results when I desisted from WebClient and switched to this API (just pass in the two strings along with zeroes for the other parameters).
[Code]...
And yet Webclient seems oriented for only two entries (username and password). How do you set up the credentials for three entries? I hate to abandon WebClient, but at this point I just don't know how to make it work.

System.Exception: Transaction (Process ID xx) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.
I suspect this
Dim webc As New WebClient
webc.DownloadFile(remotexml, targetxml)
webc.Dispose()
Then i am using the targetxml right after that:
Dim xmldoc As New XmlDocument
xmldoc.Load(targetxml)
etc.
It seems that xml file is locked by the first process (WebClient).
My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.
I've managed to narrow down my issue to a simple annoyance. I had a Webbrowser control mostly coded to navigate around an Oracle CRM On Demand site to generate metric reports, but then realized when I tried to build in the auto-download part, that the Webbrowser object wasn't going to give me the behind-the-scenes control I wanted. Searching online, it seems the Webclient control might be a better route. However I'm stuck trying to get by the login page so I can use the Download-File method to get my generated xls report. [Code] But every reply from the server has "Sign In Error: Both a user sign in ID and a password must be given." which tells me the form/post data isn't getting where it needs to go (It thinks the form is blank at [Code].
The above username and password are bogus of course, but once I can get a different reply then 'the fields are blank' I can worry about correct logon information. I'm just not sure what I'm not doing correctly or if I need to include something else. Since it's a publicly accessible site and I'm stuck getting something in the form to be 'seen', it should be easy for others to try and test.

View 2 RepliesIs it possible to resume a download with DownloadFileAsync?
If not, then how can I asynchronously download files and resume them?
I make a lot of programs that require an internet connection to download things from the web.At the very beginning, I used WebClient, as I didn't know Socket & how it worked.But now, I use Socket all the time, altough it's more lines of code. It seems to work faster then WebClient.I am interested if this is really true & why WebClient is slower (so is HttpWebRequest) then just a Socket.I've setup 2 threads which starts on the click of a button (WebClient thread starts first), the Socket beats the WebClient by just some milliseconds, but still.Each way has it's advantages & disadvantages, e.g.: if you use Socket, you need to write the header yourself & parse the response header.My question is, which one do you prefer & why ?Do you know why WebClient & HttpWebRequest are slower then Socket, as I assume, WebClient & HttpWebRequest both use tcp to download the things.
