C# - How To Cancel A Web Service Call If It's Not Responding
Apr 8, 2010
I have a web page (.aspx) that calls a third party web service to get some data. It usually takes couple of seconds to get the response back, and then the rest of the page will load. Occasionally the call gets stuck either due to the web service is down, or internet connection, etc., the page just hang there and will not load.
My questions is:
1) Is there a way to abort/cancel the web service call after a set amount of time?
2) Is it even possible to verify the status of the web service before calling it?
i am doing this in my client side to make my page load and update a message that is inside and update panel, i associate the keydown event of a textbox control to this javascript:
[Code]....
but the problem with that is if the user type fast the page will do a lot of postback, and i just wanna make the last one, how can i afford that??

I am using a LINQ to SQL data source for a ListView and perform a validation check in the Listview ItemUpdating event:
[Code]....
This works great and keeps the user from updating the record with invalid data.However, when I hit cancel after this operation, it saves the text in the box rather than cancelling the operation. Here's my code for the update button:
[Code]....
Update Function:
[Code]....
I do not handle the cancel button event, as the cancel operation has worked fine... unless someone enters incorrect information and e.Cancel is set to true.What am I doing wrong? Is it the mixture of using the LINQ Datasource and doing my own updating?
I have a text box that I am reading mulitple employee names into. If the user enters a name that does not belong to an employee I want to cancel the item_updating function. Here is my code:

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
I need to call a Rest service but would like to do so without having to redirect. Here is my dilemma. The Rest service we are trying to integrate offers the option to sign up for a subscription but does not allow us to upgrade an existing subscription. So if a user wants to upgrade an existing subscription we have to first cancel and then have the user sign up for a brand new subscription. I don't know how I can make this so it flows nicely in my code. I ideally I would like to do something like this
User decides to upgrade
Click upgrade button
Existing account is being cancelled, if cancellation was successful
New account is being created
How can I do this with a Rest service? Here is a sample URI/URL
Could anybody give me some ideas how to make this work in an elegant manner. We thought we could keep the old subscription and then just sign the user up for a new subscription for the difference of the money. For example the first subscription would be 2.95 and the second one would be 2.00 which would amount to a subscription of 4.95. I think it is not elegant and the user would see 2 charges on the credit card, weird, I think. Since I don't know much about Rest maybe there is a way that this can be solved.
I need to asychronously call a web service from an ASP.NET application. The aspx does not need the answer from the web service. It's just a simple notification.
I'm using the ...Async() method from web service stub and <%@Page Async="True" %>.
ws.HelloWorldAsync();
My problem: the web page request is waiting for the web service response.
How to solve this problem? How to avoid any resource leak when the web service is down or when there is an overload?
I need to download a file from a website to my specified folder and use in my asp.net application.The file is update everyday and i need to pull the latest file.
I was wondering why you would still use ASP over Silverlight, since with silverlight there is a lot you can do already. And you dont have to use css, jquery, js, html, etc.
Also with silverlight you can do a call to the database via ria service.
I can only think of 1 reason which is, that not every one has the plugin installed. But thats just a matter of time.

I have an asp.net MVC2 application that needs to call a web service from the controller. How do I do this? It is a RESTful service that returns Json data.
I built a web-application which calls a web-service twice in the application's log-in page - first, on Page_Load, and the second time is after a button click. When debugging, everything goes well, but after publishing the web-application and trying it - I cannot make the two calls for the web-service (each call is invoking a different function in the same web-service).
If I call it once (say, in the Page_Load) its OK, but once I get to the button click event, the page just seems to be loading but actually doing nothing (loading to infinity).
When I disabled the web-service call in Page_Load, the web-service call after the button click worked well, and if I switched between them (disabled the call in button click and enabled the call in Page_Load) the enabled one worked OK.
How come this is happening? What did I do wrong? Could it be related to the fact that the location where I published my web-application has some URL-rewriting rules?
I have a C# library. From within it, I want to call a static method that exists within the same library but through Javascript. Can I use WebResource to call a C# method?
As the title states, I'm trying to call a web service written in ASP.Net (Same solution, but different project in visual studio) from javascript. Since I added the web reference for the service prior to this for calling it in VB.Net, I tried to use this reference by directly calling it.In the body of the Default.aspx page, I have this code:
I'm going on my 3rd day trying to get my Ajax AutoComplete textbox to call my web method. Based on my google searches, I'm not alone. I suspect the problem has something to do with the ServicePath property on the extender, although I'm not sure. My web service is at the same level, on the same server as my test web page. I'm not sure exactly what should go into the ServicePath property, although I think I've tried every possibility. Below is my web service followed by my script.
using System; using System.Collections.Generic; using System.Linq; using System.Configuration; using System.Web; using System.Web.Services; using System.Data; using System.Data.SqlClient; using System.Data.Common; using AjaxControlToolkit; using System.Text; using System.Xml; using System.Xml.XPath; using System.IO; using System.Collections.Specialized; using System.Web.Services.Protocols; [WebService(Namespace = [URL])] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService]
public class Service : System.Web.Services.WebService { public Service() { } [System.Web.Services.WebMethod] [System.Web.Script.Services.ScriptMethod] public string[] AutoCompleteNames(string prefixText, int count) { System.Data.SqlClient.SqlConnection cxn = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["HumanResourcesConnectionString"].ConnectionString); cxn.Open();.....................
I have created an WCF data service in a new asp.net web application and i want to call this web service from another web application using jquery, but it always returns null.
My jquery call looks like this:
[code]....
Note that [URL] works in the browser but since the jquery call is from localhost:3410 i assume its a problem with cross domain.
I have been reading that i should use jsonp for this, but i have a hard time figuring it out.
I'm having problems with impersonation in WCF. Namely, I'm calling a named pipe service from within ASP.NET with impersonation turned on. This fails (due to permissions on the pipe blocking anyone from the network). So, is there any way I can make the call outside of the impersonation context? I don't need to be impersonating to make this call, but can't see any way of doing this.
PS. I need to do this declaratively, through config...
