I am trying to deserialize a JSON string using VB.net and cannot seem to pull the values out of the finished List.[code]I am told "Index was out of range. Must be non-negative and less than the size of the collection."
From VB.net code behind when I am trying to deserialize it it's stating that "Expecting state 'Element'.. Encountered 'Text' with name '', namespace ''."
I have a json array which is formatted as follows:
[Code]...
How can I deserialize this in such a way that I can have a list of objects indexed by property? Meaning, I want to be able to access the data like this: MyList(96).lastproperty or MyList(96).listofstuff.yetanother and have it return the proper datatype too? Is that even possible in vb.net?
I've the following JSON string to deserialize: [{"application_id":"1","application_package":"abc"},{"application_id":"2","application_package":"xyz"}]
I'm using DataContractJsonSerializer method. It is made up of array of items and I couldn't find an example using VB.Net that can deserialize this structure. I have the following Application class to store this information: <DataContract(Namespace:="")> _ Public Class ApplicationItem <DataMember(Name:="application_id")> [Code] .....
I am attempting to deserialize a simple JSON array to .NET objects using the JSON.NET library in visual basic.
For the life of me, I cannot figure out what I am doing wrong here. My JSON string deserializes into appropriate objects (9 in total), but none of the properties are populated.
My code:
Public Class result Public Property id As Integer Public Property vote_percentage As String
[Code]....
When using JSON.NET you have to have constructor methods (i.e. Sub New) in order for the properties to get set during the Deserialization call.
Sub Serialize(ByVal strPath As String, ByVal ProjInfo As ProjectInfo) ' create a filestream to allow saving the file after it has ' been serialized in this method
The following JSON call always hits the AJAX error handler, and I can't figure out why:[code]All I get is Failed to load resource: the server responded with a status of 500 (Internal Server Error)url...When I set a breakpoint in the controller, I can see that it's being reached, so I'm not sure where the request is falling down. Here's the action in the DetailController:[code]
I 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?
how to receive and send back json. Hope someone can help me on this. I understand by examples.
On my clientside, I am sending a ajax json string "name":"theName" to the server side and would like the server side to return a string saying "welcome &name ".

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.
How can I convert a JSON string to an array OR a JSON string to XML in VB.NET? I know how to do this in C#, as I have read dozens of articles on it, however, I am unable to figure out how to achieve the same result in VB.NET.
I'm using the System.Web.Script namespace via System.Web.Extensions.dll (from Microsoft).
I'm willing to use an additional DLL file if needed.
I'm sure this has been asked before but I'm not finding quite the information I'm needing so I thought I'd post this.
I've written a PHP script that returns a simple JSON object that looks like this:
{"status":"success","level":"admin"}
I'm doing a standard web request that submits the required data to the script over the internet and that's working fine.
Now, I want to use JSON.NET to pull out the individual variables so I can know what the values of "status" and "level" are. The problem is, I have no idea where to start.
I'm doing this in VB.NET (on the .NET Compact Framework).
I am accessing the facebook api and using the json.net library (newtonsoft.json.net)I declare a Jobject to parse the content and look for the specific elements and get their values. Everything works fine for the first few but then I get this unexplained nullexception error " (Object reference not set to an instance of an object)Now I took a look at the declaration but cannot see how to change it. Dim jobj as JObject = JObject.Parse(responseData) message = jobj("message").tostring
The error occurs at the last line above.I check to see if message is null and then look for the next desired field as follows
[Code]...
This is one example where "message" does not appear in the first few lines but appears later. So what I do is look for position of message and description and which ever is first go and get that and if I get an error or the fields do not return anything, I try and parse by regex and even that is not working right.
I have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX <WebMethod(BufferResponse:=True, EnableSession:=False)> Function Test(aObject as Object) as Object ' object will have been successfully serializaed into a dictionary
I can't find any example about how to deserialize AMF in vb.net. I found one in C# but i don't know how to make it working for VB. Someone is able to show me an example of parsing AMF, simple client?
I am trying to read in an XML document, add a record with a tag for the filename and write to a different XML document.I have been told I must use serialization.
HTML Dim Geocache As FileStream = New FileStream("c:emps.gpx", FileMode.Open)Dim serialize As XmlSerializer = New XmlSerializer(GetType(Cache_Location))Dim myLocation As Cache_Location = New Cache_Location
Ok, so I'm playing with some FTP profile files that are written in XML. I'm trying to get the program to be able to read the current users settings and fill in or remove servers they do or don't have access to. So the XML looks like
I have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?
I am trying to deserialize my data and I keep getting an error.I'm hoping for any ideas of what could be the problem.My code in Visual Basic Express 2010:Imports System.Xml.Serialization

How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't. I will probably code my own, along the lines of ...
[code]...
maybe later add left/top/height/width/enabled/visible, etc, bu tfor not th econtrol name an its "value" are enough (text, value, lines, checked?, etc)
