.net - Internal Server Error (500) With HttpWebRequest
Jun 20, 2012
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
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 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.
Im using httpWebRequest to get a response from a website.Ive created / creating a dvd manager for my dvds on disk. My method works fine if i double click a movie name. It will download the data into the correct directories. Im implementing a "process all titles" feature and im finding that around 15 titles im getting "internal Server error 500" or the program bombs out Could this error becoming from the poor internet speed (3G dongle) and the website rejecting my query because of slow downloading?Moved into a new house and ive no broadband in yet?

Scenario: We have a website that is viewed both internally and externally. When an error occurs the users are displayed with a detailed error page(Stack trace etc). Problem: The external customers do not need that much information about the error. We are looking to have the external customers see a message instead. Ex. Please contact Administrator. Also if possible we would like to log this message in our SQL database.
Note: I'm assuming I make a custom error page like - Implementing a Custom Error page on an ASP.Net website. but how do I determine whether or not the user is internal/external? Also is this the best way to approach the problem?
I have a set of ASP.NET membership tables online with my hosting with godaddy. I can run my site locally and connect to the online membership table fine and can create accounts etc.. So basically I got everything hooked to reference everything online.
I used a tcpclient to make a connection to a streaming API and for some reason it doesn't work with a 301 error, (something wrong with my credentials). However when I use a httpwebrequest to the same API and use the same credentials and that works.
TCPclient connection:
Try Dim bufferread(defaultSize) As Byte url = "xxxxxxxxx.com" Dim tclient As TcpClient = New TcpClient(url, "80")
I have a crawling program that fetches urls to parse the html and came across an unusual error since I started this. For a specific set of urls from a site when fetching using HTTPWebRequest and HTTPWebResponse I get the error The remote server returned an error: (404) Not Found This is unusual since it works when pasting it in my browser. Not sure if code is needed to posted but let me know if so.

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 have several programs that I wrote in Visual Basic.net 2003 that I run from a server at work. We upgraded to Visual Studio 2008 recently and I converted my code to that version. I rebuilt the .exes and tried to run it from the server. It said I needed to upgrade the framework on the server, which I did. Now when I run the .exe file from the server I get a runtime error:
Runtime Error! Program: d:... This application has requested the Runtime to terminate it in an unusual way. Please contact the applicaiton's support team for more information.
These programs are very important to the day-to-day operations of the company I work for. I did backup the software before converting it, so we're running normally right now, but there are modifications and upgrades I need to make as soon as possible, but cannot due to the programs crashing when I run the on the server.
