Error: "The Remote Server Returned An Error - (407) Proxy Authentification Required"
Nov 20, 2011
I am developing a tool to get all elements of a web page (images, links etc...) and I am having a small problem with the Download button. I click it, and becuase we use a proxy at school no matter what I try it will always throw the error: "The remote server returned an error - (407) Proxy Authentification Required"How do I detect that the user is using a proxyAnd then if so, authenticate with it so that I can download the file?
I am trying to upload a file to Mainframe machine from my VB.net application. I am getting the following error.The remote server returned an error: (501) Syntax error in parameters or arguments
Using vb.net 2005 - FtpWebRequest for ListDirectory always gets 550 error The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
On both FTPListDirRequest.Method = System.Net.WebRequestMethods.Ftp.ListDirectory
When I tried to read the data of a http link using VB.net, an error occur. The error is:The remote server returned an error: (406) Not Acceptable.This error is only occur for some links.
I have a console application created in VS2005, with a web reference created via WSDL.When I run on my local machine (and I have a browser up) I can access the web service fine (if a browser is not up I get the 407 error).I understand this,since my local client machine MUST go through the company proxy (I assume the proxy is resolved when I sign start the browser).When I copy the application to our server, the 407 proxy authentication required error ALWAYS comes up.The thing is, on the server all check boxes in internet options/connections/lan settings are NOT checked. i.e. the server DOES NOT go through a proxy.I installed wireshark to help track down the problem and it shows that when i access the web service wpad is being called and our proxy server is being called.is there a .net configuration that allows me to say "ignore the proxy".I have already tried variations on the system.net section of the app.config file: [code]It seems that no matter what we do (including changing registry settings) this application ALWAYS tries to go through a proxy.
I am writing a small ftp application for a friend and I'm not sure whats going on here. I'll try to be as descriptive as possible. I get a 553 error "The remote server returned an error: (553) File name not allowed." when I try to upload a file.
[Code]...
I added a msgbox to show me what the path to the server is and this is it.Click OK and it gives me the error above.So I changed the "ofd.Files.FileName to ofd.Files.SafeFileName My msgbox now shows this:Then VS throws en error saying it can't find the file in the projects debug folder so I move it there and run the program and it uploads. I noticed that in the first msgbox it has forward and backward slashes could that be my problem or is it something else?
I attempting to download 6 files from my FTP site to a local server using VB 2008.After 1 or 2 files are downloaded I am geeting an error Bad sequence of commands.It appears the ftp connection is not closing then re-opening.[code]Then I change the file name. After the 2nd or 3rd file, I get the error message.How would I close the connection and reopen it without having to close the program?
I've made this script to read the lines from the txt. But when I try to login I just get this " The remote server returned an error: (530) Not logged in." Even I "logged in" at the link.

Does My.Computer.Network.DownloadFile work with FTP? When I attempt to use it, I get the exception: "The remote server returned an error: (500) Syntax error, command unrecognized."
Here's the code I'm using: Dim UpdateAddress As String = "ftp://xxx.xxx.xxx.xxx" & lbDownload.Items(X).ToString My.Computer.Network.DownloadFile(UpdateAddress, BasicPath & lbDownload.Items(X).ToString, "", "", True, 10000, False, FileIO.UICancelOption.ThrowException) The FTP server is IIS6.
I am using Visual Basic (VS 2005) windows 2003 and Exchange 2003. Also I have developed WEBDAV functionality for retrieving messages from my exchange. Everything worked fine until they have asked me to move to 2007. I already know that Microsoft has de empasized Webdav but they say that they still supporting it.My problem is that every time I'm trying to retrieve contacts or inbox or whatever I getting The remote server returned an error: (403) Forbidden Below is a sample of my code
Dim sQuery As String Dim SNList As System.Xml.XmlNodeList Dim Email1List As System.Xml.XmlNodeList
[code]....
I cannot find any examples written in Visual Basic for Exchange 2007. I want to start using the webservices but I cannot find any examples. Where can I find them ? Everything is written in C++ or C#.
In an app that is deployed to a diverse user base, I have code similar to the following: [code] For all users but one or two, this is fine. But one user is reporting back that he is receiving this error message:"The remote server returned an error: (407) Proxy Authentication Required."
Just finished reading a book on visual basic "Imports System.IO" and "FtpWebRequest". I double checks this code and tripple checked it but I can't seem to find anything wrong with it, bare in mind I did write it from scratch with help from the book so maybe its full of mistakes.[code]
I am trying to fill a web form (hosted in a remote web site) from a VB NET 2.0 Application.The web form has a submit button, as usually, in order to start some process and then send the result to some emails accounts).[code]

I'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:
Server Error in '/' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 10.0.0.0 .I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help.
When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
I'm trying to upload a file via FTP from my local computer to an FTP server, which is also on my local computer at the moment. I've got this sub I'm calling:
Public Sub UploadFTPFile(ByVal ftpservername, ByVal fullfilepath, ByVal filename, ByVal username, ByVal password)Dim clsRequest As System.Net.FtpWebRequest = _ DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest) clsRequest.Credentials = New System.Net.NetworkCredential(username, password) clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.
Trying to POST a username & password to my PHP script at www.example.com/web-service.php which gets that info and echos true or false.

Am I missing anything? It stops and throws that error on the line that calls GetResponse()?
I am using process.start to start Excel.The filename argument has blank spaces in the path and the argument is truncated at the first space.The error that is returned says the file cannot be found.
When i use the FtpPutFile() of Wininet.dll to upload the files, there is no error returned (hence the function returns 'true'), but the file on the ftp server is just a partail image. Hence the upload process is not completed but the ftpputfile() cannot trap that. Any reason why? Or how to get trap those errors?
I am trying to make a DLL for a proxy class of a web service as:[code]Do i have to include system.web.services.protocols.dll but i read it is included in system.web.services.dll then why it is complaining about certain members of the class.Here "Service" is my webservice and "proxy service.vb" is proxy class whose dll is need to be created.
I am running my application and at random times when it is unable to connect to the database I get an error saying "A Transport-level error has occurred when receiving results from the server. (provider, TCP Provider, error: 0- The specified network name is no longer available.) How can I stop this pop up from coming up? It comes up every once in a while and I want to disable that.
