Prevent Errors When Doing A Webrequest - (500) Internal Server Error
Dec 26, 2010
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
[code]....
How would I be able to prevent these errors?

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:

The target server is writen in Cold Fusion and i have no access to there.
In addition i get only this error msg: The remote Server returned an error: (500) Internal Server Error
What can i do in order to come with a more friendly exception message?
Am i overlooking something obvious in my code? myResponse.Close()

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 have sql server2000 encypted stored procedure. I can not modify them. Typicaly all the procedures manipulate row by row different tables using cursors etc. When the stored procedure is executed at the Query Analyser screen, I see error being thrown in between but the procedures continues till all the records have been processed. This behavior is acceptable to the client. I now need to automate the process using VB.net 2002 windows application. I call the procedure from vb.net but the program throws runtime error on the 1st occurance of a error in the stored procedure.

I've written a JavaScript function which validates form input and highlights the input fields and displays any error messages, which I have tested and all works fine. i have called this function from the OnClientClick attribute of an asp:Button tag. However, if the JavaScript function determines there to be validation errors, I want to stop the form from submitting. How do I do this?

I am using Synclock to prevent multiple threads from logging text messages to the same file at the same time, but this doesn't seem to work:I get frequent sharing errors on the logfile, within the synclock block.The Synclock is using the variable holding the filename, because it exists all the time and because it is always the same object, whatever class instance or thread I'm in.[code]Despite using Synclock and a Using block around the code, I keep getting this error in the sw.WriteLine(Msg) line:System.IO.IOException: The process cannot access the file '(filename)' because it is being used by another process.Should I use some other type of object than a string to synchronize on?I cannot use a user interface object (button or so) because it is a windows service project.It was written and compiled in Visual Studio 2008, but targeting the 2.0 framework because it has to be able to run on some old Win2000 machines.

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.

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'm developing a application and it contain server and client. Whenever client application or client gets any error or exception, error message should writes to error.log file placed in Server. Assume there is no shared driver or there is no any way of entering server credential user name and password. I have done a testing with listening socket and once application convert as Windows Service, it does not work anymore. But as UI it work fine.

Here's an interesting problem, and I'm looking for a pattern that will keep it all workable. I am building a smart-client app for a school system. It will contain information about students including their report cards, sick days, and so forth. it will generate student-level reports, including their report cards, each rich with very personal commentary by their teachers. The app will retrieve data from the remote server via web services.

I created a server-client application using the asynchronous socket. I found the problem when closing a socket on the server, applications so closed. The procedure that I do to close the socket server is:
Terminate the listening thread. Close the client socket is still connected to the server. Close the server socket.
How to prevent the application is closed, when I close the server socket?
Protected Friend Sub CloseServerSocket(ByVal IPAddress As IPAddress, ByVal socketPort As Integer)

I am in the following situation: I have been requested to write an application for managing where we have customers - this must flag up when we try to add a customer too close to another one, so must be able to calculate distances based on post codes.I have chosen to use ASP.Net VB because I am fairly good at that and I like that the browser does all of the layout for me (using Java or C# would mean having to position each element individually).I have copied a few files from the company's website (which I also wrote) and modified them to account for the database structure we need for the new app.I have designed the database to account for the requirements of the new app.I have set up a website in IIS on port 81 through which to view the app.
