WCF / ASMX :: Send Large DataTable From WCF Service?

Jan 10, 2011

I am trying to send System.Data.Datatable from a WCF service, to a C# Windows Forms application. When I execute, I get follwowing message:The maximum message size quota for incoming messages (65536) has been exceededThe datatable I am trying to send can get quite large. What would be the best approach to send the DataTable across without hitting message size limit, or in other words, what are ways around this problem?

WCF / ASMX :: Web Service - Convert Datatable To XML

Mar 23, 2010

I have a web service that is running and it shows a list of employees with their information. I created the web service with the following code:

[Code]....

The problem is 'Null' values in the datatable don't show up as empty tags in the XML so when I read the XML from the web service this is no consistency. Is there a way to show the tags even when the fields are null in the datatable or is there a better way to accomplish what I need. I'm reading this web service from a silverlight application with the following code (this application works but, it doesn't show all the employees as it skips over when no tag is present):

WCF / ASMX :: Error While Retrieving Data From Wcf Service In Datatable

Jan 20, 2011

I have created a WCF Service which is returning a DataTable. It is successfully build and hosted in IIS7 and also working fine when i am returning a string only. but it gives me error (below) when i am returning a DataTable.

"The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error."

This is how i am calling my WCF Service.

Possible To Return Large Data From WCF Service To Web Service

Feb 3, 2010

we have console-hosted WCF Service and ASP.NET WEB Service (on IIS).
After some tough operation WCF Service must return some data(large data) to ASP.NET Web Service for next processing. I tested on small results - everything is ok.
But after testing on real data(serialized result object is near 4.5 mb) error occurs on ASP.NET Web Service (which is client in wcf-client-server communication).

Messages size are configured by next binding (on server and client):
NetTcpBinding netTcpBinding = new NetTcpBinding();
netTcpBinding.TransactionFlow = true;
netTcpBinding.SendTimeout = new TimeSpan(0, 4,0, 0);
netTcpBinding.Security.Mode = SecurityMode.None;

Cannot Send Emails With Large Attachments In VS 2010

Sep 21, 2010

I've gone through this link. (http://connect.microsoft.com/VisualStudio/feedback/details/544562/cannot-send-e-mails-with-large-attachments-system-net-mail-smtpclient-system-net-mail-mailmessage)

It is not possible to send an e-mail with an attachment larger than 4 MB in .NET Framework 4.0. The same code works for small and large files if you set the target platform from .NET Framework 4.0 to .NET Framework 3.5. So this cannot be a problem with our mail-configuration! I get no error if I attach e.g. 10 files of 2 MB! I searched through Google but I didn't get it.

Workaround solution is not working fine as expected. After using this workaround for a while, I found that some files are corrupted. So this is not a solution for this bug.

We've applied that Microsoft patch and we're still seeing the issue?

Send Large Amounts Of Email Via C# Web Page?

Dec 6, 2010

I have part of a project whereby I need to send 1 to up to 2000 emails from a webpage. One open source bug tracker used a Thread to send emails but it was riddled with bugs. So just want to know if anyone has any ideas of how I can create a procedure that send up to 2000 emails a go?

I was told by one of my colleagues to leave it as one process (normal routine sending one email at a time) as it won't take long to process all the emails anyway. Doesn't seem right and I want to use threading... maybe I like complex routines?

[Extra]
I have something like:
foreach(string email in emailAddresses)
{
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add(...)
...
SmtpClient client = new SmtpClient();
client.Send(mailMessage);
}

WCF / ASMX :: IIS Memory Increasing For Each Client Request In Asmx Web Service?

Nov 8, 2010

A 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.

C# - How To Efficiently Send Large Files From The Database To The Browser

Jun 1, 2010

In my web application I am working with files. Some files are very large. I use Response.Write() to write the file to the browser. This goes well for the smaller files, but for large files this can take a while and the bandwidth is fully used.

Is it possible to split large documents and send it piece by piece to the browser? Are there other ways to send the document quicker to the browser?I hold the document as a property of an object.

WCF / ASMX :: Server Rejects Large Amounts Of Data?

Jan 16, 2011

I have an asmx web service I am "Upgrading" to WCF. It's function is to pass a DataTable to the Remote Server. It works fine as long as the dataset contains under 20 records(more or less). Anything greater than that returns the error:

The remote server returned an unexpected response: (400) Bad Request

Everything I searched on the web says I need to increase things like maxBufferSize in my Web.Config File, but like so many others, it has produced no results. This seems like it should be a simple fix.

I am using VS 2010 on Windows 7. All Development and debugging is being done on the localhost. What I currently have for my web.Config file is below:

Submit A Form With A Large File Upload And Send Ajax Requests?

Mar 8, 2011

This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.

So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.

I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
