I have some xml data. I've made an asp.net soap based webservice that takes the xml as a byte buffer applies xsl transformation to it and converts it to a docx file. But when i return the docx file using the response object i get an error that client found response of type application/vnd-word but it was expecting text/xml.

Context.Response.ClearHeaders();
Context.Response.ContentType = "application/vnd.openxmlformats- officedocument.wordprocessingml.document";
Context.Response.AddHeader("Content-Disposition", "attachment; filename=" + "test.docx");
Context.Response.Flush();

WCF / ASMX :: Need Details On Returning An Entire Existing XML File From A Web Service?

Jan 20, 2011

I've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?

But my webservice isn't hosted on the same folder of my website.

I mean: [URL] Is it possible to put a webservice on the same folder of the main website? Or it's not a problem ? (Can I retrieve the files in the webservice's folder from website?)

JQuery UI Autocomplete WebService Source Returning JSON?

Nov 29, 2010

I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.

There are several issues:

1) The autocomplete function is not firing
2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception
3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return.
4) I am not at all certain that this code will accept JSON data that comes back from the service

Here is the code:

WCF / ASMX :: How To Execute WebService Asmx Link From Default.aspx Page Link Using HTTPRequest And HTTPResponse

Nov 3, 2010

I have spent a couple of days on this one. I have an ASP.NET website that has Linkbuttons on

the Default.aspx page.. I added a WebService to the Website because later on the WebService will

subscribe to a Provider(Feed) of News, Sports and Weather and things like that. So when a Linkbutton

on the Default.aspx page is clicked it will connect to the link in the WebService which will load the News,

Sports or Weather onto the Default.aspx web page.

The problem is I can't get the LinkButton to execute the Link in the WebService. The link will call the page up

to where you see all of the Web References. But then if you want to execute one of those references you

have to click its link and the Invoke button that will follow. My questioh is how can the link on my Default.aspx

page execute the link in the WebService. Now I changed the LinkButton into an <a href> but I still can't execute

the link in the WebServices. I always use www.Microsoft.com as the link when testing and I wasn't sure about the return type

so I put "void" for an HTTPRequest, so below is the link from the Default.aspx web page and below that is he asmx file:

WCF / ASMX :: Alternatives To Returning A DataTable From WCF

Dec 7, 2010

I have read a lot of posts describing why it isn't good practice to return heavy objects like DataTable/DataSet to the client from WCF. However, there doesn't seem to be much discussion about the alternatives (or maybe I'm not looking in the right forums).

My problem is this: I've tried to convert my DataReader/DataTable into a List<List<string>>, where List<string> represents the data in each row, but get an error at the point when the data is being sent to the client. A simple List<T> or a one-dimensional array gets returned without any problems. But whenever I try to return a collection of collections, there seems to be an issue. I don't know until runtime what my DataReader would look like as different stored procs are called based on user selection from a web form.

What am I missing here. Is WCF not able to handle collection of collections (I know that multi-dimensional arrays are not supported)?

WCF / ASMX :: Service Returning Old Values?

Sep 14, 2010

I am developing an application with WCF services. The basic functionaloty of a screen is to provide an entry screen to add particular entity. Once save even fired It will save the data to the database and call the bind method to bind into the grid by refreshing the latest data.

When I am running the site from my source (Visual Studio) , it works perfectly. When the client calls method to fetch the data the WCF service, it returns latest (added) data. But the issue comes in the server when it works with IIS. I deployed the code in the server, once the data added I am getting the old data only. But after two refresh I am getting the latest data.

what required to be done to get the latest record.

Also, how can I test the difference in payload sizes when returning a DataTable Vs List<DataRow>?

WCF / ASMX :: Returning Web Methods As Different Formats Based On Querystring?

Mar 23, 2010

I have some WCF services that I want to return in different formats based on a querystring param. For example, [URL], [URL], [URL], etc... This would make it so that many different types of clients could consume the services whichever way was easiest for them, such as binary for a .NET client and json for an ajax or Flex client.

What I'm thinking is that I can have the WCF web methods return their .NET business objects and not worry about the output mode and then have a behavior that hooks in after returning from the web method which checks the querystring for this param and either:

1. Continues returning the business objects if the mode is dotnet.

2. Converts the business objects to xml if the mode is xml and returns a string of xml.

3. Converts the business objects to json if the mode is json and returns a string of json.
