Webclient Getting A Internal Server Error When Downloading A String?
Nov 12, 2011
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:
I'm trying to filter submitted web sites by attempting to browse them while bouncing the request off of OpenDNS. If the page received is the OpenDNS page, I'll assume the page shoudld be blocked.
How might I accomplish this task using the System.Net.WebClient class?
I'm trying to connect to a remote server (from our customer) via HttpWebRequest.GetResponse but at the login page i'm always getting an exception: "The remote server returned an error: (500) Internal Server Error." In the response stream i see that i was redirected to the error-page. The code worked so far(HTTP status 200) with the old ASP-website but they'll migrate to ASP.NET soon. There's no error if i browse to the URL manually. This is the (reduced) code:
I receive three errors using the following function:
Private Sub readWebpage(ByVal url As String) Try Dim req As System.Net.WebRequest = System.Net.WebRequest.Create(url) Dim resp As System.Net.WebResponse = req.GetResponse
[code]....
The remote server returned an error: (500) Internal Server Error. The server committed a protocol violation. Section=ResponseStatusLine
I am using WebClient.DownloadString method in vb.netto convert asp.net page to string after that I send this string by email. by I got this error from the server
The remote server returned an error: (500) Internal Server Error.
Unfortunately, no more details about the error. what is the possible problem ?
error in the following line of code :
Dim str As String = client.DownloadString(Request.Url.GetLeftPart(UriPartial.Authority) + "/GFOPortalA/isd/ViewForm.aspx?ISD_FRM_NO=" + Session("ISD_ReqId"))
I am trying to use WebClient to download a .zip file from my server. In debugging mode the code works perfectly, but when I deploy my software the file does not even begin to download.After my program checks to see if an update is available, it should download the .zip file from my web server via the following
I am trying to make a download manager for my program. But when I run this code it gives me the message box say "Download Started" but that is it. I do not get any file downloaded or progress bar change? Does anyone know why?Public Class frmDownloader
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click WebClient1.DownloadFileAsync(New Uri("https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft_Server.exe"), "C:hi.exe") MsgBox("download started") End Sub
I'm trying to download a file in vb.net but the url I'm downloading from redirects to a generated url like this [URL] but the web client doesn't seem to pick this up. Is there any way around this?
I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.
I'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.
I am getting an error with this Dim Web As New WebClient Web.Proxy = "69.196.16.237:62159" It says runtime errors may occur when converting string to System.Net.IWebProxy What does that mean?
Basicly I'm downloading XML files with the Webclient class for processing and caching in a local database. There are three different categories of data, each contains 1 to n numbers of XML files. To retrieve the XML file I ask the server with following parameters in the URL:
I am new to code signing.After I swtich from the temperary test certificate to a real certificate from a CA, when I publish, I got two errors"Error 1 Cannot publish because a project failed to build.""Error 2 SignTool reported an error 'An internal certificate chaining error has occurred.'."and when I checked "Sign the assembly", when I build, it asks for a password, after I entered password, it says "Cannot find the certificate and private key for decryption"
This error first appear to occur randomly. Steps to recreate:Open Visual Studio and load a solution (some files automatically opened) - this is when the problem occurs Close all open files Restart visual studio and load solution (no issues)Open Exactly the same files again, restart visual studio and load solution so files open automatically (problem occurs!)
However, when trying to narrow it down to a single file (that is automatically opened when the solution is loaded), I couldn't reproduce the problem. Now with all the files open again the problem doesn't occur!!! So it looks like it is fixed - though this happened before and eventually the issue came back.
I think it is to do with one of the user controls with DevExpress controls on it - when the error occurs, the designer displays the error. Though I can't reproduce it at the moment to confirm that.
Is it possible to have an internal XML dataset within a VB 08 program I ask because we at present have the program load an external XML on startup, but i would prefer this to be internal withing the program to stop other editing the XML file.
Been a while since my last posts, so i'm kinda back again ^^ Me & my friends are gonne have our annual LAN party again next weekend, and I'm usually the one in charge of taking care of things, setting up the network etc etc. One thing i've noticed over the past 4 years, is that it usually takes us a day to get everyone set up correctly, all games up to date etc etc.
I am using the web client to download a file. Which works ok. However, now I have to download many and the number of files to download will change everyday. I am not sure how I can get the web client to know which files have been downloaded or not? I was thinking of using a for loop to download each file. But I will never know how many there are to download? The web client could download the same file twice?

I am using the code below to upload a file to a server running windows IIS 5.1.
I am just testing on my own computer to see if this works ok. However, I keep getting the following error message:
The remote server returned an error (405) Method Not Allowed I am sure this is a IIS problem maybe something to so with permissions. However, I am configure the virtual directory to allow read, write, and directory browsing.
The config.xml file I am trying to upload is located in the same directory as the executable and does exist.
Private Sub upload_config_to_server() Dim url As New Uri("http://localhost/softphone/config.xml") Dim wc As New WebClient()
