Error: Object Required.
am having a web service that fetches some couple of results. When i run the service independently in my firefox, it returns the required result. But when i use Ajaxautocomplete in my page, it returns no result. The page is binded to a master page and is in a folder thats attached to the root folder....i.e. My page is in ~/Students/Default.aspx. My Service is also in a folder where i prospect to put future services...i.e. ~/Services/WebService.asmx.Here is a code for my webservice

Here is how i call the service in my Default.aspx page

I have modified the sample HomeController to illustrate I problem that I have in my real application. In my real application I want a user to not wait for a longer running background process. I found that the response is not being returned to the user until the background process has finished which defeats the purpose of having a background task. Here is my modified sample MVC 2 application to illustrate.
[Code]....
When I click on About from the home page it takes ~20 seconds for the About page to appear. If I remove the Sleep(20000) from the background task then the page appears instantly. I expect a BackgroundWorker task to run in the background! What am I doing wrong?
I have an ASP.NET site and I've been doing some work refactoring code to try to remove some long running processes (in the order of an hour) from the actual http Request by creating a BackgroundWorker and sending the work off to that to process. This was running fine on cutdown tests but when I applied the logic to the real code I found problems accessing Session variables from the code running in the Background Worker. It seems that the HttpContext object that was passed has a null session and if I ask for HttpContext.Current I get null back.
I'm assuming that this is because they are in a different thread and that the session and HttpContext.Current are both reliant on being in the same thread. Is there any way I can get access to the Session from the background worker or am I stuck with finding all the variables I need from session and putting them in an usable data structure and then putting them back in session (if appropriate) afterwards? It obviously complicates the refactor massively if I need to do this so I'd rather not.how I might do this other than BackgroundWorker processes
I am trying to have a marker show whether or not a particular service within the services.msc is running on a remote server(s). I have a service called Yardi Services on a virtual server. I want to be able to show on a dashboard I am creating for work, whether this service in running or stopped. For some reason this service will randomly stop though I have a auto restart on error. I am assuming that I would need to create a web service or use WMI?

I need to run a javascript function before my code behind runs. my element looks like :
<asp:Button ID="SuperaddsSMSPnl_Button1" runat="server" Text="Smsa" CommandName="smsa"
CommandArgument='<%#Eval("addsid") %>' CssClass="knapp" Style="left: 180px; top: 20px;" />
and in code behind I use
Dim smsbtn As Button = it1.FindControl("SuperaddsSMSPnl_Button1")
smsbtn.Attributes.Add("onclick", "showSign(this); return true;")
to show in progress sign while code behind is doing its job. but I want code behind to run by using commandName
I am using a Global.asax in on my webpage to run a function with an interval. In this test I have set the interval to 1 minute to be able to see what happens.
I have declared a timer in the Application Start which should mean that when I open up the webpage after I have uploaded the Global.asax the timer will start.
However with this code below where I try to create a file named newFile.txt, this file is not created. I cant really understand what I could be missing. It seems that the function is not running ?

I have the following code which should update a label to say "wait..", then run a function, and then update the label again to say it has completed:
<asp:Button ID="Button1" runat="server" Text="Upload"
onclientclick="document.getElementById('errorMessage').innerText='Wait...';"
onclick="Button1_Click" />
This works fine in IE, but not in Firefox.
When I run it in Firefox the label does not change until the process completes.
Is there a way to force the JavaScript to update the page before running the C# function?
I have an aspx page that on a button click creates a BackgroundWorker and then calls the RunWorkerAsync method. In my aspx file I have set Async='true' but when I run the application and click the button it appears as though the page waits to refresh until the processing of the BackgroundWorker is done. How do I get control to return to the page (and have the page refresh) after the BackgroundWorker is created and started?
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += RunJob;
worker.RunWorkerCompleted += JobCompleted;
worker.RunWorkerAsync();
I want to retrieve values from a function at regular intervals and display it.I have two different fucntions 1 for getting values and 1 for display.I am using backgroundworker for that.
So when i put continous loop it goes into infinite loop without displaying data.The problem is with asp.net ..
What have i done is
public void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs
e)
{
if (this.backgroundWorker1 == [code]...
Now until it doesnot come out of DoWork method if doenot display data eventhought it called Display_data() method.
I removed whilke(1=1) and checked that after exiting DoWork method it displays data.
So is there any way that after data binding in Display_Data() method i can display data and then refresh the whole process at backend ?

I created a simple web service in VS2010 (C# - XP Professional SP3 development computer -- running .Net 3.5/4.0) that just does the basic "Hello World" and changes Temperatues from Farenhet to Celcius functions and ran fine in VS2010. I then created a directory in C:Inetpubwwwrootwebsvcvs10a (of the same development computer). In the localhost IIS I converted this to an application directory (properties/create application). I tried to deploy my web service here using the publish wizard of VS2010 but was getting errors stating that the URL was not in the correct format, so I decided to just copy myService1.asmx, Web.Config, and the bin folder (which contains the compiled assembly) directly to C:Inetpubwwwrootwebsvcvs10a. Then from the localhost IIS I tried to browse myService1.asmx and received the following error:
Configuration Error
Description:An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.
Source Error: [Code]....
Source File: c:inetpubwwwrootwebsvcvs10aweb.config Line: 6
Version Information: Microsoft .NET Framework Version:2.0.50727.3615; ASP.NET Version:2.0.50727.3618
--I tried changing the targetFramework to 3.5 in web.config, but that did not fix the problem. I then removed the targetFramework attribute from web.config and then got this error message:
Could not load file or assembly 'myVS2010Websvc' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.BadImageFormatException: Could not load file or assembly 'myVS2010Websvc' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
What can I / should I do to resolve this problem so that I can deploy this web service project to localhost -- don't I already have .Net 4.0 runtime on this machine? It is the same machine that is running VS2010.
I used visual webdeveloper 2008 express edition to make a new WCF Service Application.If I test it on my pc it works perfectly , But if I publish it to my shared hosting site I get this erroris has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'.
View 1 RepliesI have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
View 2 RepliesI have an application I am trying to write that generates a text file conforming to a file specification, and the file could contain thousands of lines. This part is easy. The more challenging part for me is the user interface. It needs to be a web interface with various options to affect what data gets on the file; this part is no problem. The process for generating the file, though, could take a little time depending on the amount of data , and I would think the web page would time out.
What options do I have for the UI? Could I create some sort of service that the page calls and runs in the background? When the process errors or is finished, I'm thinking there could be an email sent out, or even messages displayed on the page.

I am deploying a public ASP.NET website on an IIS7 web farm.
The application runs on 3 web servers and is behind a firewall.
We want to create a single page on the website that is accessible only to internal users. It is primarily used for diagnostics, trigger cache expiry, etc.
/admin/somepage.aspx
What is the best way to control access to this page? We need to:
Prevent all external (public) users from accessing the URL. Permit specific internal users to access the page, only from certain IPs or networks.
Should this access control be done at the (a) network level, (b) application level, etc.?
