JQuery And WCF Service - Stops Working With Error
Jul 15, 2010
I am creating an application that uses jQuery to make ajax calls to ASP.NET WCF Web Service. Everything works fine most of the time but eventually (about twice per week) the service stops working with the error below. The only solution is to clear the ASP.NET Temporary Files. The problem seems to start by the time the application pool recycles but not on each recycle. Please help as I'm trying to figure this out for weeks now!
WebHost failed to process a request.
Sender Information:
System.ServiceModel.ServiceHostingEnvironment+HostingManager/6957828
Exception:
System.ServiceModel.ServiceActivationException:
The service '/Chat2/Chat.svc' cannot be activated due to an exception during compilation. The exception message is: Could not load file or assembly 'App_Web_vpupi5wr,
Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.. --->
System.IO.FileNotFoundException: Could not load file or assembly'App_Web_vpupi5wr, Version=0.0.0.0,Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Basically i'm using the plugin to validate a form. I've got the basics set up and working. Now i'm trying to use remote so that I can check for a duplicate email address. The problem is as soon as I add my checking script the validation stops working on the email field completely. It constantly says "please enter a valid email address" no matter what I put in the field. If I don't have the remote bit in my code the email field validation works correctly.

I have a ASP.NET wizard that I need to use jQuery to manipulate some of the CSS styles. For example if a certain criteria is met it will hide a button:
$("input[value='Continue']").css("display", "none")
This works great on the first page, but subsequent pages (loaded as controls .ascx) don't work. The wizard doesn't load a new page each time, but simple reloads part of the content using the built in wizard feature.

I'm using some JS to show some divs.The divs' content is set up in a MultiView control in the server. Depending on certain parameters, I trigger some postbacks to make the server select the appropriate view. The problem is that everything works if I keep the alert(1); below, but stops working if I remove it.
Here is the code. I have a button which its OnClick() calls ShowEditor(), with an element and a type. ShowEditor() makes the editor's div visible after raising a postback to let the server select the correct view in the MultiView based on the type. This works fine. The editor loads and there is a div inside (vwText_Text1) which I'd like to assign an OnClick event to. This only works if the alert() is present.

I want to load a popup when a user clicks a button. The buttons are images located inside a tabpanel. The first time the page is loaded the helpEvents DOES display the popup and the 'click' popup. Then I navigate to Tabpanel tab2, and the helpTickets button doesnt work (doesnt even display the 'click' popup) Then I navigate back to Tabpanel tpEventDetails, and the helpEvents button doesnt work anymore either(and also doesnt even display the 'click' popup anymore) So I think something gets lost in the updatepanel on callback...but what? and how to fix it?
default.aspx
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<cc1:TabContainer OnActiveTabChanged="TabChanged" ID="tabContainer" runat="server" ActiveTabIndex="0" OnClientActiveTabChanged="ActiveTabChanged" Width="100%">

<img src="/images/help.png" id="helpTickets" alt="help" />
</ContentTemplate>
</cc1:TabPanel>
</cc1:TabContainer>

script.js
//CONTROLLING EVENTS IN jQuery
$(document).ready(function() {
//LOADING POPUP
//Click the button event!
$("#helpEvents").click(function() {
alert('click');
centerPopup('Contact');
loadPopup('Contact');
});
$("#helpTickets").click(function() {
alert('click');
centerPopup('Tickets');
loadPopup('Tickets');

I have a div called address which as a textarea. When I click a hyperlink, it toggles the div up and down. After clicking a an asp.net button the div collapses which is fine, but I noticed the url turns from [URL] to [URL] and now the toggle does not work. Here is the script:
$(document).ready(function () {
$('#myAddress').click(function () {
ShowHideAddressBox();
});
$('#arrowIndicator').click(function () {
ShowHideAddressBox();
});
});
function ShowHideAddressBox() {
var str = $("#myAddress").text();
if (str == "Hide") {
$("#myAddress").html("Click here");
$("#arrowIndicator").attr("src", "/Shared/Images/misc/arrow_state_grey_expanded.png");
}
else {
$("#myAddress").html("Hide");
$("#arrowIndicator").attr("src", "/Shared/Images/misc/arrow_state_grey_collapsed.png");
}
$('#checkAddress').toggle('normal');
}
The server-side button click just sets some values in a couple textboxes. In my master page, I have the following line as well:
<asp:ScriptReference Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Name="MicrosoftAjax.js" Path="http://ajax.microsoft.com/ajax/3.5/MicrosoftAjax.js" />

I have a simple web service that isn't working with a standard jQuery call. The code is below. The jQuery will execute and succeed, but on debugging, the service argument is always null. I've had it separated as 4 string params in a json string and that didn't work either. I must be missing something on the config side, but I can tell what it is.

I have a web service that was running on Server 2003, IIS6. The service required an SSL connection. The service expects 4 parameters; a User ID, Password, Record ID and the "type" of data requested (one of 5 options). The service validates the user then simply performs a select of the record ID from a table determined by the type specified. This service was up and running for a couple of years. I installed a couple of new servers a couple of months ago. The users that makes use of this service just tried it and couldn't get a response. I checked the server and I hadn't copied the service over. The service is located in a virtual directory under the primary web site.
For example, the site is: [URL] Service virtual directory is "GetITSData" The call to the service has been: [URL] param1, param2, param3, param4 and the service would return the appropriate data. I "assumed" that when I copied the actual contents of the directory over, that the service would then begin functioning again (since it was empty). All IIS snap-in manager items for the virtual directory match the previous settings on the old server (I still have that server available in my office). The main site requires SSL and uses forms authentication. When I create a dummy site in VS2008 and try to add a service reference, I get the following: There was an error downloading [URL]. The request failed with HTTP status 403: Forbidden. Metadata contains a reference that cannot be resolved: [URL]. The remote server returned an unexpected response: (405) Method Not Allowed. The remote server returned an error: (405) Method Not Allowed. If the service is defined in the current solution, try building the solution and adding the service reference again.

Running solution with VB.NET & C#, ASP.NET, VS 2008 with ReSharper 5 Most of the time, ReSharper is working (redundant code grayed out, squiggles, etc.) Sometimes, on the same code where it was working, nothing is highlighted to show ReSharper is enabled. I haven't done anything except modify code and debug. What is going on that turns it on/off?

I have a custom dead letter queue service to pick up messages from DLQ. This service picks up failed message from DLQ and tries to resend to a different end point. If the new endpoint doesn't work, it rolls back transaction. This works great. Here is the code.
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Single,
AddressFilterMode = AddressFilterMode.Any)]
public class FDPDLQService : IFDService
{
FDPManager _fdpManager = new FDPManager();
[OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
public void ProcessFDMessage(FDMessage message)
{
//System.Diagnostics.Debugger.Launch();
try
{
MsmqMessageProperty mqProp =
OperationContext.Current.IncomingMessageProperties[MsmqMessageProperty.Name] as MsmqMessageProperty;
// if message log required, and configured, log the incoming message
try
{
ChannelFactory<IFDPRouter> factory = new ChannelFactory<IFDPRouter>("IFDPRouter_EP");
IFDPRouter proxy = factory.CreateChannel();
string ep = proxy.GetNextEPForGivenEP(OperationContext.Current.IncomingMessageHeaders.To.ToString());
if (ep == null || ep == string.Empty)
{
throw new EndpointNotFoundException(Common.Constants.FDP_NOT_FOUND_EXCEPTION_MESSAGE);
}
// Process message with next end point available
_fdpManager.ProcessFDMessage(message, ep);
}
catch (EndpointNotFoundException enfe)
{
ExceptionManager.HandleException(enfe);
Transaction.Current.Rollback();
//throw;
}
catch (Exception ex)
{
ExceptionManager.HandleException(ex);
Transaction.Current.Rollback();
//throw;
}
}
}
}

This works great.
But if all endpoints are not available for a long period of time, and if service rolls message back to the DLQ for a long period of time, after a certain period of time service stops picking up messages from DLQ. I am not sure which configuration is responsible for this.

When I'm accessing web service from jquery, I'm getting the 403 forbidden error.. I published and created in the virtual directory too. Wat's the cause of this error and how to rectify it? I've added the webservice in the same solution.. This is my following code..
$(document).ready(function() {
$("#sayHelloButton").click(function(event){
$.ajax({ [code]....
I suppose using that url path for webservice is wrong.. I used the path 'DummyWebservice.asmx'. There I'm getting the 500 internal server error.

data: '{"testSuitName" : "' + testSuiteName + '"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
},
//If the call fails
error: function (xhr, textStatus, errorThrown) {
alert(errorThrown);
}
})
}
I get undefined error. If I return string from service it works. Do I need to change dataType: "json" to something else?

I developed and deployed a web application using ASP.NET,C# successfully. The application was running perfectly until few days back. [NOTE: It still works fine on local machine (tested using both development server and IIS)] What happens now is: The website opens perfectly. After few operations which involves database interactions, in all the pages, the pages stop responding. I mean, after a few clicks, if I try another operation the page starts postback for unlimited time period and never gets rendered
and a following message is given: The connection was reset: Firefox 3.5... IE cannot display the web page: IE 7, 8 There is no database connectivity issues. I checked event logs on the web server and found few unhandlled exceptions, I corrected those. Now the event log doesn't show any error. But the problem is same.
I tried accessing the page from web server's browser, everything works fine. Even my boss can browse all pages with no problem (both have Win Server installed). Other machines (mostly XP) can't browse after sometime(as described above). I checked the memory usage, cpu time - NO ISSUES.

I'm trying to write some code that checks the number of days between two dates, when I set the date on my IIS7 server to anytime in the future I get the standard "Internet Explorer cannot display the webpage" screen. This happens if I comment out all my date checking code, with todays date it loads with any future date it doesn't. I've tried rerunning IISReset which makes no difference.

If you do a search for "ie8 back button disabled" you'll see a number of blogs with people having difficulties with the Internet Explorer version 8 back button becoming disabled. This now happened to one of my ASP .Net pages. The page uses a user control, aspx page, and a master page. It uses no redirects and seems to be happening when I click the back button and then the forward button (after the forward button is clicked, it does not fire the Load event and the back button becomes disabled). Has anyone else encountered this and do you have a solution for it?

So we have three 2008 R2 Servers where two are configured to be web servers (IIS 7.5), and the third a session state server. I have set the SessionState and MachineKey settings in the applications web.config. After I restart the two web servers I can log into one server, then change the IP address to the other server, and I am still logged in. Success.
I can typically log in/out with any user account I want, change the ip address back and forth, and all is well until some random time between 30-60 minutes when I log in to one server, change the IP address, and the new server asks for credentials.
This is the sessionState setting in both web.configs:
<sessionState mode="StateServer" stateConnectionString="tcpip=xxx.xxx.xxx.xxx:42424" cookieless="false" timeout="30"/>
The application resides under the default web site, and uses the default application pool. I am using forms authentication with a timeout of 20 minutes. I am not receiving any error events on any of the three servers when this happens, and restarting the two web servers fixes the problem for a while. The two web servers are not clustered per-se, but will be served round-robin via a network device.

When running the ASP.NET Development Server, everything is working fine. However, when I deploy my asp.net application to the production server (IIS 7.0 integrated mode, fresh install), my location tags in my web.config file are being ignored.
Case in point: I'm using forms authentication, and when the user arrives at my login.aspx page, the external css & js files are not being loaded...even though I have specified that those files should be available to all users (auth'd or not). However, once the user is logged in, the files do in fact load.
<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" timeout="2880" />
</authentication>
<authorization>
<deny users="?" /> <!-- Restrict anonymouse user access -->
</authorization>
And the exception to my css file...
<location path="Styles/xtools.css">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
I've verified that the path to the css file is accurate.
--EDIT Forgot to mention, I have tried creating a web.config file in the targetted folder as well...still not working.
