When a json result is returned by the controller the object name seems to be missing, I normally wouldn't mind but the flexbox jquery plugin requires the json result in a particular format.

I'm strugling the whole day with the next JSON string
{
"0":{"link":"afbeeldingenplaatje1.jpg"},
"1":{"link":"afbeeldingenplaatje2.jpg"},
"2":{"link":"afbeeldingenplaatje3.jpg"}
}
How can i deserialize this? What's wrong with the next code (vb.net)
Public Class DataString
Private m_link As String
Public Property link() As String

It returns always an empty result.

I have a JSON response from a web service that I need to be converted to an object then to an array. My response is similar to the one below:
{"status":{"error":"NO","code":"200","description":"none","message":"Request ok"},"geolocation":{"lat":"38.89515","lng":"-77.0310"},"stations":[{"country":"United States","regPrice":"0.00","midPrice":"0.00","prePrice":"0.00","streetAddress":"1401, I St[code]....
I am doing this is VB.NET within a console for now. Basically I am trying to create a simple way to test my API calls and output the information. What I am trying to accomplish is having to loop through the JSON array and list the stations.
My ASMX call is returning Content-Type = text/xml; charset=utf-8
I am using ASP.NET 3.5 and jQuery.Ajax. Have added these things are per numerous suggestions from Stack Overflow. I have done these things
Done this at web.config
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false"
type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

But whatever I do, the response header is still of type xml. What part am I missing here?
I have created a function which essentially enables me to output anything I need from my database in a similar method to Facebook's FQL querying method as a JSON text result. I can also use the same function to get the output as a Dictionary, or List of(Dictionary) to use with VB functions for other purposes.
[Code]...
I am using the Facebook Toolkit and making a request using FQL.Multiquery. I am using the following code which returns the correct data:
Dim query1 As String = String.Format("SELECT post_id, actor_id, target_id, message FROM stream WHERE source_id in (SELECT target_id FROM connection WHERE source_id={0}) AND is_hidden = 0", FBuserId)
Dim query2 As String = "SELECT pic FROM user WHERE uid IN (SELECT actor_id FROM #firstQuery)"
Dim queries = New Dictionary(Of String, String)
queries.Add("firstQuery", query1)
queries.Add("secondQuery", query2)
Dim result As List(Of Facebook.Schema.fql_result) = q.Multiquery(queries)
When I run this 'result' list is populated with the results of the two queries in XML but I am unsure how I can send this list to the browser in JSON. I am using asp.net MVC.
I am trying to return a json string via jQuery of an object using the following function. The problem I do not seem to be able to overcome is my json result comes out the other end wrapped in double quotes.

I have a MySQL database with a table called "Locations" which looks a bit like this
id | name | other parameters
1 | shop1 | blah
2 | shop2 | blah
[Code]....
This works, but it is inefficient calling the database through the loop, how do I avoid this?
I'm trying to setup a WCF web service to be consumed by JavaScript using JSON and jQuery.I've noticed that you can send JSON without a DataContract if the service method parameters match the naming structure of the JSON object:
<ServiceContract(Namespace:="http://foo.com/bar")>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>

How do I call a function with System.Threading with parameters and get the return? Normally my code would be:
StrInput = GetString("A")
How can I do this with multi-threading? Is it possible to call this function several times without having to create a new thread each time or a sub that I then run as a seperate thread?
There is a stored proc.. Which was returning to result sets..
Ex:
select * from table1
select * from table2
If I get this data to a Dataset, Definitely I will get 2 data tables with index (0,1)..But what if go though a Datareader? I had checked that just now.. And I got a result of first result set (i.e Table1 in our example)..
I have the following value 48.81, it comes as a string from the database, I need to convert it to decimal, I'm using:
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture)
I'm receiving 4881D and I need 48,81
I thought CultureInfo.InvariantCulture was going to help me with that
EDIT:The coordinate value is 675900.244.I'm "spliting" it like this:
Dim Degress As Integer = Coordinate.Substring(0, 2),
Dim Minutes As Integer = Coordinate.Substring(2, 2),
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture),
[code]....
This is the value of the coordinate in the database?

We are trying to consume WCF service which returns employee details in JSON Format.like:

View 1 RepliesI am looking for a vb.net library where I can insert data into an object and have it spit out a json formatted string, and also take the string in again to rebuild the object.I am not that concerned with mapping it to preexisting objects.I have searched around and every single library I've found either can't read the strings in again, interprets them as one long string instead of breaking them up into parts, or fails to work entirely (asp.net can't even find any public members).

Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?

I'm getting a JSON response after accessing a web service with my window application written in VB.NET. How can I convert the JSON response to a VB.NET object and vice versa?
View 1 RepliesI am been stuck on this for 3 days now...I have been accessing the twitter api to pull a user_timeline for a list of users and the json that comes back is impossible to work with. I tried to deserialize it using javascriptserializer and get an error:invalid object passed in , ':' or '}'
Now this is frustrating since I expect the json being returned to be error free. Then I tried json.net and split the posts using string.split and tried to convert each post to Jobject or jarray. for Jarray I get
'unexpected end of content while loading jArray
[Code]...
Now I have formatted the code here and not pasted the whole file but it does look like valid json to me and I do not alter anything after receiving the stream from the twitter api. Can someone please point me in the right direction? I really need to get this stuff parsed?
If an object is created inside a function and the function returns that type of oject how is the memory handled.
Example:
Public Function GetEmployee(employeeid as integer) as employee
Dim oEmployee as new employee
oEmployee.FirstName="Bob"
[code]....
Does the variable that receive the object still a pointer to the memory location that was used inside the function?What about when you do a oEmployee2=oEmployee.Is oEmployee2 just a pointer? And any changes to oEmployee will now affect the other. Just trying to understand it from a memory perspective and how that scope works?

I'm working on a small game that is based on a map of grid squares.I have a class (clsGrid) that stores a few properties for each grid square.The grid square objects are organized into a list(of clsGrid).A loop and stream reader are successfully reading properties from a text file, putting the properties into grid objects, and adding the grid objects to a my list of grids. When retrieving a grid from the list of grids, I'm getting unusual results. Regardless of the index I give the list, I always seem to get the last indexed grid in the list.The debugger seems to suggest that the right numbers are being read into the stream reader and they are being added to gridHolder. However, the message box at the end will always show me the LAST grid.id, regardless of the index I give it.
