I'm getting a strange data download from an Access database.Using Visual Web Developer 2010 Express, I created a web service that places records from an Access database in server cache and then reads the records, one at a time, from the cache. The data in the records is converted to a delimited string. The web service is called from an e-learning program called Toolbook that places Http Post calls to the web service. The web services uses vb and .Net Framework 2.0.
All works correctly with one exception. When a record in the Access db contains "&", it is downloaded to the Toolbook e-learning program as "&". If I place && in the record, I get "&&".If I download the data from the Access db using a classic.asp file rather than the web service, the "&" displays correctly.
I get this error when trying to access a self hosted wcf service...

Can someone explain what I need to do to get this to work, I do not have any cross domain policy file. And don't know how that is supposed to look like.
I have a web service which is accessible from the browser. When I try to access the same web service which is hosted on Windows Server 2008 R2, from an excel Macro, it says
Run-time error '-2147220991' (80040201)':
Server was unable to process request --> The request failed with HTTP status 404: Not Found.
The excel macro works fine when I try to access the same web service on the other server(Windows 2000 Server)
The web service is developed using .Net 2.0.
I'm posting the URL for the web service for your reference.
URLs which are not being accessible from Excel.

Both Web services and Excel macros are old applications which have been running fine for years. The only change is that the application is being migrated to a new server(MCDEAGDWEB202) which has Windows Server 2008 R2 and SQL Server 2008.
The Old server(MCDEAGLWEB005B) has Windows Server 2000 and SQL Server 2000.
I have added a web service as a reference to a windows application using "AddWebRefrence" option. And I am unable to access the funtions in the web service but instead i get the functionnames followed by the completedeventargs and completedeventhandler.
What am I doing wrong and how can i access the funtions in the web service.
have two different applications. The only access between those two applications is Web Service.I want to delete records in the another application database by passing primary key of that table.I don't have access to database where I have to delete the records.For this, where I have to write the delete functionality.? In web service or or in my application.

this method i can access using asp.net but not by using a android.. i have checked for the headers etc.. the response is OK in android while debugging but the data is not inserted..
what is the equivalent of stringbuilder in android??
in android i use
StringEntity se = new StringEntity(json.toString());
//and post the data to my service...
post.setEntity(se);
what is the equivalent of stringentity in C# and what can i do for this prob?
In my ASP.net website we are going to use Silverlight to display some interactive diagrams. The users can add, edit and delete various diagrams on the silverlight front end. Silverlight will call Web Service methods to save the changes into the database. Besides the data being passed by silverlight to web service call, we also need to pass some data from the session (like logged on user id etc.) to the web service call.
My question is that how silverlight can access session data? I am trying to pass session information via a webservice method call over to Silverlight but, the session variables inside the web service methods are returning null value.
The Web Service is running under the same web root where the ASP.net website using Silverlight is also hosted. I have made EnableSession = True for web properties.
I have created a dynamic web page . It gets loaded using a file keys.txt. This file holds the keys which are used to display a web page like panels order, text of labels , number of buttons and so on..It is consuming a web service written in delphi. All works fine but when 2 users try to access this service simultaneously then a error is displayed (Internal Server Error 500) "Access violation at address 0040404C in module "accelerate_gateway.dll". Read of address 00000000"Accelerate gateway is the name of delphi web service.It seems to me the problem of multi threading in delphi service ??But I have not done any multi threading in client asp.net page as well. ??It simply creates web service object and access its methods.As I am using a file contents to load a page, so I am concerned if it can create trouble as well ?? . Although I have used FileShare.ReadWrite in it.

I am a newbie to ASP.NET (but not to C#)I have a project I am developing that may seem unconventional at this point but it is a project that I hope to eventually expand and provide a new type of service on the internet. Currently the project makes use of an Excel spreadsheet that is generated by another application I wrote. Basically the spreadsheet is an index to a specific type of file that exists on a host computer and the files are directly linked from within the excel document. When the link is clicked it opens the file using the operating system default program which then processes the file (this takes some time).
This is fine and dandy but when I click on another file, the default program immediately stops processing one file and opens the latest submission and thus interrupting the previous job. To prevent this I am now writing a queuing application. Here is where ASP.NET comes in. I do not want the link to open the queuing application with the file to add into the queue as a parameter because that pops one or more nnoying/scary "you are opening an executable" dialogs and because I want to be able to access the queuing service from a remote computer, and possibily in the future over the web. Instead I am trying to use an ASP.NET service application that will accept the name of a file as a parameter, access the external queue class (defined in an external dll of which only one universal instance is allowed), and add the request to the queue. Whether or not the table is an excel table or on a web page, using a form in this instance is tedious, not only for me but for a user. I want the user to be able to simply click on an html link and have the file be queued without anything except maybe a confirmation page pop up saying that the file has been queued and it will take x amount of time before the file is finished processing.
My problem is I cannot for the life of me find a way to do this. I have searched the interenet for over a week now looking for a way to call a "WebMethod" using a link and I am getting the impression that it cannot be done. Even when I use a form and try to have the form pass a string (representing the file name) as its "action" it comes up with an application error saying that I am missing the parameter I am trying to pass. Here are some examples of what I have tried:Here an example method I would try to access:

Most WCF web service I have developed were consumed in a server side code (by adding a service reference in visual studio or creating a proxy class using svcutil.exe. I have never consumed a web service in a client code. So I apologize if I am using wrong terminology or my question does not make sense.We have a browser add-on or plugin that connect to a device on client computer (think of it as active-x control for internet explorer) inside a asp.net web page.This browser plugin/add-on then will be sending measurement data to the web server. After some research it appears to me that I can do eithera) Develop an AJAX enabled WCF web service and use script manager and javascript to consume it inside the web page that interact with browser pluginb) Develop a WCF web servcice (not sure about AJAX enable) that serialize request and response to JSON, and use JQuery inside asp.net page to consume it.QuestionWhat's difference between approach a) and b)? Which is better in particular scenario I have described.

Is there any properties I need to set on the web service object to get this to work? I'm confused as to why it's not working.

I created a Class library for WCS service (MyWCFServiceLibrary) to access data form my database. The database connection strings have been defined in Properties->Settings.settings. The endpoints are defined in the app.config. Tracing and logging is set to write to files on local server. This service is hosted by a .net web service. This webservice refrences the WCF service using MyWCFServiceLibrary.dll and MyWCFServiceLibrary.pdb. The web service is hosted in IIS. All this setup is working fine on the development environment.Now I want to deploy this in the QA environment. Since I am a newbie with WCF, I would appreciate some help on what needs to be done for deploying this on the QA server.1. Do I need to recompile the MyWCFServiceLibrary.dll after changing the connectionstring to point to QA database and tracing and loggint paths to the new server?2. Is there anything that needs to be done with end points or anything else?

There is a term beginning with "w" which is an ASP.NET which allows javascript to access and call WCF/ASMX services.It is just like scripthandlerfactory,and the term is not webmethod or webservice(the attributes),but something else.Does anyone know what this term/feature is called?
View 1 RepliesA WCF web service with the right class and method attributes can be accessed as a JavaScript file in a script tag. That is:

View 2 RepliesA customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
