Intermittent timeout calling ASMX web service yet Upload data transfer completes OK

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :.NET Framework
I'm calling my webservice from a web page and getting a timeout despite setting very high values in my web.config files. This occurs intermittently when the file is usually pretty large but yet the file is still getting uploaded completely (as if the timeout DID NOT occur). Here is a function in my .aspx file which calls my ASMX proxy class:
private void UploadFile(HttpPostedFile postedFile, string fileNameOnly) 
    // create an instance of the proxy class to talk to our service; calling it client:

VS2005 calling VS2010 asmx service returns empty string


Anyone have any experience with this?

We are using VS 2005 for the front end, and vs 2010 for the web services part (asmx), not wcf yet.


Web service works just like the vs2005 when run locally, no problems.


Connecting to it from a test app returns an empty string. Connecting to a 2005 app doesn't!

Anyone run into this before or have a suggestion? Surely vs 2005 can connect to web services from a later version?






Service Operation - Get proper data when browsing the service, but not when calling the service from

Hello, I recently implemented a service operation in an attempt to pass some filter parameters to a data service (a user guid and an organization, actually, for impersonation of a user on the service's call to the application). I successfully added the service operation to the data service, and I can browse the service and see the data filtered as I expected. However, when I call the service operation from the Silverlight client, I don't get any results, even though I should. Am I missing something? Code below if it's helpful. Thanks! Service Operation Definition: [WebGet] public IEnumerable<opportunity> filteredopps(string userid, string org) { /*Define the connection with the impersonated user*/ CrmConnection crmc = CrmConnection.Parse("Authentication Type=Passport; Server=https://" + org + ".crm.dynamics.com/" + org + "; User ID=myuser; Password=mypassword; Device ID=mydeviceid; Device Password=mydevicepassword"); crmc.ImpersonatedUser = new Guid(userid); var crmOnline = new DataContext(crmc); List<opportunity> uplist = new List<opportunity>(); crmOnline.UsingService(service => { var query = from o in crmOnline.opportunityopportunities select o; foreach (opportunity thisopp in query) { uplist.Add(thisopp);

Webservice timeout while calling windows service



We have a .net product built in .Net 2.0.
It consist of three blocks.
First is a asp.net web application which calls webservice which in turn call a windows service to get results from database.
Our problem is that windows service is taking time to get results from database because of which timeout is occuring.

Now we have already set timeout property in web application while calling web service through proxy. However, we could not find how to set timeout property for webservice(This will stop webervice from timeout before windows service send back the result).

If somebody have done it, please help


How to improve the speed of data transfer in WCF service using basicHttpBinding


Hi All,

                I come across an issue in transferring 2MB file into the server through WCF service from my Windows Mobile client using 3G connection. Application takes around 2 minute to upload fine into server.

It’s an image file is there any way I can improve the speed.


I used basic httpBinding and WCF Service accepts file as byte array.

E.g. Operation contract.

Int UploadData(byte[] inImage)

Thanks ,

Calling a data-driven web service method asynchronously


I am trying to write a Windows Service which will call web service methods based on a run schedule.  I have setup a ‘schedule’ table which holds the name of the web service method and some scheduling details (e.g. run every day at 0200).  I am using VS 2005/vb.net.

My service creates a timer which runs every minute and when the timer is fired the schedule table is read and  any entries which are due to fire are actioned.  This could mean multiple methods being fired at the same time.  As some of the methods are overnight batch processes and may take some time, I don’t want processes to wait for others to finish before being actioned.  As the methods themselves write to the system log to report their success or failure the scheduling service does not care whether the job fails or not – it is simply doing a ‘fire and forget’ exercise.

What I need is some code which will fire a data-driven web service method asynchronously.

I have investigated two types of method call.  The first is a simple InvokeMethod:-

mywebservice.GetType().InvokeMember(ScheduleRow("WebMethod").TOString(),(Reflection.BindingFlags.InvokeMethod Or Reflection.BindingFlags.IgnoreReturn), Nothing, mywebservice, Nothing)

The second is an asynchronous call:-

Dim asyncCall as New AsyncCallB

Using Conditional Split data Transfer in SSIS 2008

This article uses the Integration Services Conditional Split Data Transformation element to filter and transfer data from a set of flat text files to SQL Server database table. The concept can be easily extended to apply to any other source or destination such as Microsoft Excel. This scenario is useful in creating denormalized database tables in a reporting and analysis situation.

Posting data to ASMX and return Object for jQuery


I am using fluent NHibernate with WebForms and I am trying to build a page where I allow a user to post a status update on their profile page and I a using a .asmx WebService to post the data to the database and then returnig a StatusUpdate instance to the page to be used by jQuery. I have a couple problems.

1) First off when I return a string from the WebService(i was testing) the textbox where the user enters their status doesnt empty the contents. And since the page doesnt refresh even if I manally clear out the textbox and put in something else, it still posts the previous status to the database again. How do I fix this?

2) Secondly, when I return the StatusUpdate Object from the Webservice I cant the results to display anything. Like I sad, Im using jQuery to make an AJX call to the WebService.

Here is my code:

User Profile Page:

Status: <asp:Label ID="status" runat="server"></asp:Label><span style="font-size:.7em;"><asp:Label ID="statustime" runat="server"></asp:Label></span><br />
<textarea id="statusBox" rows="3" cols="40"></textarea><br />
<input type="button" value="Update Status" onclick="SetStatus(); return false;

Service Station: Run ASMX Without IIS


When the Microsoft® . NET Framework first shipped, it introduced a breakthrough Web services framework known as ASMX. The motivation behind the ASMX design was to simplify the process of developing Web services as much as possible so that even if you're not an XML expert, you can get a Web service up and running.

BITS: Write Auto-Updating Apps with .NET and the Background Intelligent Transfer Service API


Both the .NET Framework and Windows have some very interesting APIs for creating applications that are capable of updating themselves automatically over a network. There are many advantages to writing your application to update itself like Windows Update does, including convenience for your users, from easier maintenance to network administration. Automatic updates require attention to factors such as discovery, security, and file replacement. In this article, the author covers the BITS API as well as a number of features of the .NET Framework that take care of these facets of auto-updating using the same facilities that the Windows Update uses.

Marshalling Your Data: Efficient Data Transfer Techniques Using COM and Windows 2000


The way you choose to transfer data is vitally important in a distributed application. Windows 2000 provides several new features that allow you to transfer data more efficiently. Lightweight handlers allow you to write smart proxies that can cache results and perform buffered reads and writes, minimizing the number of network calls. Windows 2000 also allows you to use pipe interfaces to transfer large amounts of data efficiently through a read-ahead facility. This article illustrates several ways to improve data transfer in Windows 2000 using these new features. It also reports the results of transfer time tests and provides recommendations for transferred buffer sizes.

Writing Data to database with jQuery Forms, ASMX Webservice, & JSON - help!



Can someone point me in the right direction on how to submit data from a jQuery form to a ASMX webservice? I have gotten everything on the form ready to be submitted to the database and now I am stuck on how to send it over using $.ajax(). Everything I have read tells me how to get data from a webservice and display it with jQuery, but not the other direction nor how to access the json data within the within the webservice service(similar to a Request.Form approach with ASP.NET forms).

In other words: 

1. What do I need to do to my webservice to make sure it can receive data from the jQuery form. 

2. What do I need to do in jQuery to receive an acknowledgement the save on the server side was successful. 

I can explain more if need be, but if there is a comprehensive tutorial on not only reading, but also WRITING data with jQuery, JSON, etc. I would love to get pointed in that direction. 

How do consume an ASMX service?

Can you please give be step by step instructions on how do i do it?

I am using VS 2008 VB or C# is fine by me.

I had checked on various forums and its not really giving me the required steps (baby steps here)

Thanks a lot
