Twitter Json - Unable To Convert To Jobject Or Jarray Using Json.net / Javascriptserializer?
May 9, 2012I 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?
Using JSON.NET To Parse JSON Generated Through PHP?
Mar 2, 2010I'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).
C# - Parse JSON String Into DataSet?
Nov 16, 2011I have to the replication.That time have to pass String as JSON
{"Table1" :
[
{"Name" : "MyCustomer","Description" : "cutomer","Status" : "1"}, {"Name" : "Kiraa","Description" : "My","Status" : "1",}[code]......
This is my format of JSON result. I want to convert to DataSet.I have installed JSON.NET library. I am using C#.net
public bool convertJSONToDataSet(string strBusinessUnit, string strExecutiveCode, string strTableName, String jsonContent)
{
DataSet dataset = JsonConvert.DeserializeObject<String>(jsonContent);[code].....
here this statement is wrong DataSet dataset = JsonConvert.DeserializeObject<String>(jsonContent); how to covert to a JSON string to a Dataset.

View 4 Replies.Net Regex To Parse Specific JSON Format
Feb 20, 2010I'm writing a little web service which generates SO/SF/SU/MSO user flair in the form of an image with various "themes". I find this preferable to using the HTML/JS solutions offered by SO as it's more flexible and also works better in forum signatures.
I'm retrieving the data using the apparently unofficial API (More info here). I can have the data in HTML or JSON. I assumed the JSON would be easier to parse.
Unfortunately, I'm not great at regexes. and the best I can come up with is some very hacky sub-stringing. I believe a regex should be the most elegant solution
regex that matches ID, GravatarURL, ProfileURL, DisplayName, Reputation and Badge Counts (Bronze/Silver/Gold).
FWIW This is to be used in a VB.Net project (in case that affects the syntax at all)
[Code].....
In case any of you are interested, some screenshots of the flair as a work in progress are available here: Me, Jeff Atwood, Joel Spolsky

Convert JSON String To JSON Object?
Jan 18, 2012I 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:

Convert JSON To Array OR JSON To XML?
Jul 17, 2011How 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.
.net - JSON Parsing Using JSON.net?
Feb 15, 2011I 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.
C# - Parse An Expression And Retrieve A Parse Tree?
Jun 8, 2012I just want to parse simple expressions like IIF(FVAL(PFC) = TRUE, (IIF((ORGVAL(BAS, "2012/12/31") + ORGVAL(DA)) < 6500, (FVAL(BAS) + FVAL(DA)) * 12%, 780)), 0)`After parsing this I should be able to know what functions contains what parameters.
[Code]...
I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.
I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")
NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.

Asmx Json Serialization Versus Wcf Json Serialization?
Nov 24, 2011I 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

Twitter Library For .NET Developers?
Aug 26, 2009after a lot of work and late nights, I finally have something to give back to the VBForums community which has helped me so much.TwitterVB is a library for communicating with Twitter. It's 100% Visual Basic.NET and coded against version 2.0 of the .NET Framework. It is free, and it is open source.
TwitterVB contains a working implementation of OAuth, which allows your application's name to appear in tweets.I hope that this library proves to be useful to VB.NET developers who are looking to develop their own Twitter applications.TwitterVB can be found at http://code.google.com/p/twittervb
If you'd like to see a working implementation of TwitterVB in action, you can look at the Twitter client that I built with it: Quitter. Like TwitterVB, Quitter is 100% Visual Basic.NET. It is also free and open source. Quitter can be found at[URL]..

Parsing A Twitter Xml Document Into Variables In .NET?
May 4, 2011I need to parse an xml document from twitter selecting certain nodes and placing the value in variables.I get an error...Conversion from string "user/screen_name" to type 'Integer' is not valid. Parsing XML is out of my league.
First the Twitter XML file...
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
<status>
<created_at>Sat Apr 30 04:10:46 +0000 2011</created_at>
[code]....
Now the only problem which will be a simple fix is a retweet doesn't display correctly because the nodes are different so I'll just add a If then to see if it is a retweet then adjust the nodes accordingly.

Twitter Control Program Using VB Studio 2008
Mar 30, 2009I'm trying to recreate this feature for a twitter control program using VB Studio 2008. I want the users to be able to sign up their account in my application so they don't have to go to the site and do it.
Because captchas are dynamic images, I cannot pull the image from a src file. I'm pretty new to vb.net so, how would I initiate a session, with the webbrowser control or webclient, and be able to display the captcha image for that session on my form.
