Getting data out of objects in a JSON response

I would like to take WCF Data Service and produce JSON output to consume on various mobile apps.

Can anyone give me a how-to on the JSON part?  I.e., what is different than normal XML outut?

Thanks.

Besides your typical e-mail services, Microsoft Exchange also provides the service infrastructure you need to build extensible knowledge and workflow management systems. Understanding Collaboration Data Objects (CDO) is the key to accessing these Exchange services for your own programs. With CDO you can automate tedious tasks and integrate information such as e-mail, calendars, and contacts with almost any application. This article explains how CDO enables you to access Exchange services, then walks you through a sample application that reads calendar events from an Exchange server and sends pager reminders to your users.

Hi, 

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. 

Hi there,

I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A. I'm trying to stream an array of bytes to A, but it seems like the Response.BinaryWrite method completely overwrites any heirachial controls (I can't see any of B's other controls besides the image).

How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.

A's code:

        public void UpdateImage(byte[] imgbytes)
        {
            Response.ContentType = "image/jpg";
            Response.BinaryWrite(imgbytes);
            Response.End();
        }


Thanks!

I was reading the article Freezable Objects Overviewand came acrosee the statement

"If  your class contains non-dependency-property data members that are DependencyObject objects, you must also call the OnFreezablePropertyChanged method each time you change on of their values, even if you're setting the member to null. "

I quite do not understand the part about non-dependency-property data members that are DependencyObject objects. Can some one explain exactly what this means? If a data member is derived from the DependencyObject  class how then can the data member be a non dependency property?

I am also trying to locate some source code / project that overrides the OnFreezablePropertyChanged method, and have yet to find any on the interenet.

If anyone know whe
