I get an error on da line objPost.Close();.....the unusual error is that when I debug this code line by line slowly using F10 in visual studio 2010...the code works..but when I just run the program or even debug the program fast...it throws an error at that line.. it gives an error that the connection which was expected to be open was closed by the server..
I have created a webservice in 2010. And when I call it from my web application sometimes,It generates the follwoing errors:-1. The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.2. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.I have already tried increasing excutonTimeOut etc.

I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
I am trying to "behind the scenes" log myself into a website, from the VB code behind my ASP.NET website. But I am dumbfounded as to how to do this.
As far as I know I should be using the WebRequest or Webclient class. That is about as much as I know. I am not sure how to use the class.
I want to click a button on my website and have its Click event send a username and password to another website. This other site isot affiliated with mine. I realize the concept may seem stupid, but I plan on taking this further later, but Just need to know this now.
I have MVC application (applies to non MVC as well) where a user is posting in data. I need to take this data, send it off to two seperate end points (one using a WebRequest form POST and one using a Web Service), parse the result, and send the result back to the original user.
The issue at hand is that both end points take about 20-30 seconds to respond (response is a string) which means that I should probably execute these two calls asynchronously. At the same time I want to wait to respond to the original user until I get both results back. I am guessing I might have to use some sort of object lock so the response does not get sent back before the two calls are complete?
Based on the responses I decided to go with async controllers since I am already working with a MVC application.
I have a remote website and it requires login id and password to enter and i want to enter into that website with httpwebrequest. How it is possible?
View 1 RepliesI have an .Net Framework #4.0 application that makes a large number of web requests using the WebRequest/WebResponse classes , as i see it has memory leak (or maybe i am doing something wrong)I Wrote some small simple application that demonstrates this:
class Program
{
public static void Main(string[] args)[code]...
The only one solution i came up with is use GC.Collect() (unmarked in example) , All the object are disposed , all streams are closed , am I missing something ?I found something but i don't understand the reason , if i minimize Console the memory usage decreases and looks O.K , what can be the reason for that is there a problem with Conosole or WinForm .
I'm trying to connected to a third-party server, that allows API access via XML post/response. I've created just a very simple test page with a button to press.... the button should just go to the URL, log in with basic authentication and then return the response. if I use a browser and go to the URL, I see the XML response. Usuing my app, I'm still getting 401 unauthorized. I've been at this for hours, I've searched the forums and googled extensively, still no luck. Also, this is an internal app to internal server so security is not the highest priority. I'm setting the UN and PWD for authentication in a simple form.
Here's my VB code behind:
Dim request As HttpWebRequest
Dim response As HttpWebResponse = Nothing
Dim reader As StreamReader
Dim result As String
'disables self-signed SSL cert errors
[Code] ....
And the username and password are 100% accurate - as I mentioned above the code (well, implied).
I feel like this SHOULD be pretty easy: Overall request for testing: Submit a web request to a URL, disable the SSL check (self-signed certs used), login with basic UN and PWD I supply, return the response to a textbox.
I have 2 questions
Question 1: What is the difference between web service (asmx ; WCF) and System.Net.WebRequest?
Question 2: When should I use web service? When shoud I use System.Net.WebRequest?
I have created a simple webrequest script to return the HTML content of a remote site and everything works great on almost every site I tap. However, the site I want to utiilize this script on returns no content. It does return headers, but no content!! Does anyone know if AJAX or some other method could be utilized to block the use of webrequests?
View 3 RepliesNeed to have the server make a POST to an API, how do I add POST values to a WebRequest object and how do I send it and get the response (it will be a string) out?I need to POST TWO values, and sometimes more, I see in these examples where it says string postData = "a string to post"; but how do I let the thing I am POSTing to know that there is multiple form values?
View 2 RepliesI have a web application running from 2 servers. I'm using 2 servers, because if 1 is not responding for any failure user can access the application from other server URL. Now I want to do the redirection automatically. That means, user will enter the URL of the primary server if it is not responding then it will automatically redirect to the other server URL. How can I do that using ASP.NET and C#?
View 5 Repliesi have a website where i want to keep the session alive while user has browser open?
View 9 RepliesI was wondering wich's the best way to "keep alive" the InputStream of the FileUpload Control.I would give you one example. Let's assume you have the FileUpload control in one WebForm, and you want process it in the next WebForm (after Response.Redirect).It would be great (unless for the memory) to have something similar to:
Session["PostedFile"] = this.FileUpload.PostedFile.InputStream.
Unfortunately, this results in:
System.ObjectDisposedException
logging to another website and uploading file to that site.

This is quite straight forward. I'm calling a web-service (.asmx, with session enabled) from a c# application. I want each call to be with the same session key as the previous one (as opposed to creating a new session key each time).
Here's my (nothing-out-of-the-ordinary) code:

I have to keep a datacontext alive in a WCF service. This object is created on every call to the service, by the way decreasing performance. How could I keep this object alive with WCF.
View 2 RepliesI have a few web servers behind an Amazon EC2 load balancer. I'm using TCP balancing on port 80 (rather than HTTP balancing). I have a client polling a Web Service (running on all web servers) for new items every few seconds. However, the client seems to stay connected to one server and polls that same server each time. I've tried using ServicePointManager to disable KeepAlive, but that didn't change anything. The outgoing connection still had its "connection: keep-alive" HTTP header, and the server kept the TCP connection open. I've also tried adding an override of GetWebRequest to the proxy class created by VS, which inherits from SoapHttpClientProtocol, but I still see the keep-alive header.
If I kill the client's process and restart, it'll connect to a new server via the load balancer, but it'll continue polling that new server forever. Is there a way to force it to connect to a random server each time? I want the load from the one client to be spread across all of the web servers. The client is written in C# (as is the server) and uses a Web Reference (not a Service Reference), which points to the load balancer.
I gather customer information on a asp.net page (.net 2.0) then I want to open a new page / window which will be passed all the payment details and then connect to our payment service provide to process the payment. Once done the payment window is then close and the original calling window is updated with the result of the payment.
I can do all of the above, except I don't know how to go about opening a 2nd IE window leaving the calling windows on the screen whilst passing parameters and retrieving the result.
My best guess would be:-
Stuff all the parameters into session state var's
Open a new windows / page pickup the session state var's
Process the details
Write the results back to session state var's
Close the new window
Pickup the results from the session stae var's
I have used session in my application for admin panel. It is redirecting if i not use 1 or 2 minutes. I need to stay session until I click logout button.
View 1 RepliesI'm trying to make an executable in VS2008 that will read a webpage source code using a vb.NET function into a string variable. The problem is that the page is not *.html but rather *.aspx.
I need a way to execute the aspx and get the displayed html into a string. The page I want to read is any page of this type: [URl]
I have tried the following code, which works properly for html pages, but generates the wrong source code with "access denied" for the page title when I pass in the above aspx page.
Dim myReq As WebRequest = WebRequest.Create(url)
Dim myWebResponse As WebResponse = myReq.GetResponse()
Dim dataStream As Stream = myWebResponse.GetResponseStream()
Dim reader As New StreamReader(dataStream, System.Text.Encoding.UTF8)
Dim responseFromServer As String = reader.ReadToEnd()
