I have one asp.net application, in this i am using Javascript serializer for serializing a dataset followed by convertion to the list. That code is shown below.
JavaScriptSerializer json = new JavaScriptSerializer();
strJson = json.Serialize(aclDoc);
But, at the time of deserializing i got one ArguementException like Invalid Json Primitives with my Json value. My json value is
I've been tasked with implementing a JSON feed on an asp.net website that will be consumed by 3rd party apps (such as IPhone, Android, etc) and I'd like to follow best practices.
An example of what I'd like to achieve would be something similar to: [URL]
I've chosen the JSON.net api as this seems to be highly recommended.
My Google-fu must be failing me as I can't find a single full example code for an Asp.net web application with JSON.net implemented on it, so I've no real concept of where to begin.
My question is fairly simple:
Should I create this sort of feed as an ASPX, or ASHX file? Or even a .NET Web Service? (Remember that the tools that will be using this feed are on external apps like IPhones, etc)
I created a test feed in both ASHX and ASPX format ... here is the code (I'm using Subsonic to populate the collection) ... are either of these along the correct lines?
I had used Calendar control to enter Date. In localhost, when I save the date, it works fine and save the date. But when i had uploaded the application, it gives me error invalid date format. How to get rid of this error?
I have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query. The created file looks like the following:
{ "myData": { "randomNumber": "129", "Application": "MyMapApp", "FeatureId": "ALL", "Feature": "ALL", "spatialQuery": "FEATURE_ID= '11111' AND REQ_SEQ_NUM= 1 AND RAND_PARAM= 129 OR FEATURE_ID= '22222' AND REQ_SEQ_NUM= 2 AND RAND_PARAM= 129" } }
I want to read the data in the above sample JSON data and then populate my textboxes something like this:
txtRandParam.text = "129" txtApplication.text = "MyMapApp" and three more text boxes after that.
I use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
strange error message in IIS after updating Windows 7 (x64) with SP1. Open the IIS Manager Browse to an exisiting Virtual Application (or create a new one) Open its Basic Settings dialog Click Test Settings The error message comes up. It's happening with new Applications and also with ones that were already there (and without that problem) before. The applications themselves continue to work.

I have written a code that go to controller using json and get the date from controller. Every thing works fine when running locally, but when i deploy my application to server, i am not getting the data returned from controller using jsonreturn. One more thing My firewall has blocked the GET. So how to resolve this.
//On Page var URL = "/Home/AsyncGetCheapestList/" + param; $.getJSON(URL, null, function(data) { // displaying data content ; }); //On controller public JsonResult SetServiceIdServiceName(string asyncInputs) { List<string> st = new List<string>(); st.Add("one"); st.Add("two"); st.Add("three"); st.Add("four"); return Json(st,JsonRequestBehavior.AllowGet ); }
Here GET is blocked by my firewall so unable to get the data. Is that any other way to get it.
We have a cookie management library that writes a cookie containing some sensitive information, encrypted with Rijndael. The cookie encrypts and decrypts fine in unit tests (using Moq), works fine for MVC web applications, but when called from an ASP.net 2.0 website, the cookie cannot be decrypted. "Padding is invalid and cannot be removed."
We are sure that the cookie value is valid because we tested it 10,000 times with random data in a unit test. There is something about what ASP.NET 2.0 does when it reads and writes the cookie that causes trouble.
I'm following the ASP.Net MVC3 tutorial. When I'm in step [URL] I meet a problem with the SQLExpress and EFCodeFirst. In the step, the EFCodeFirst is expected to generate the database("Movies") and table ("dbo.Movies") automatically. But after I navigate to [URL] only the database ("Movies") was created, there's no "dbo.Movies" table inside at all. Here's the error stack:

I uploaded all the files of Umbraco CMS to the my http://blog.domain.com and also modified the web.config file. When I point to blog.domain.com, it is giving an error written in the subject. The hosting type for the subdomain is physical hosting not subdomain on subfolder
So, I have a second web.config file in this subdomain. The first one is in the main domain. I hoep this doesnt make a differnce. Here's the screenshot: [URL]
I checked the database user with which I am trying to login in to the DB and it has the db_owner permissions for the database.
Also, I tried googling for the similar issues to see if someone with similar error had resolved the problem. Here are some pages but I haven't been able to find a solution.
Everytime I run this with my form it says Invalid User.It acts like it looks up the information but returns a null reference or doesn't actually find what it is looking for.Any help would be extremely appreciated I've been stuck on this issue since Friday,asking for help in another topic on this forum.
Ok forced to use IIS7.5( begin puke puke puke end) and of course nothing works. Let's take it from start.I created a project and i started IIS7 and created a new website,added the host and checked the security permissions of the folders.I saw most of the features are done automatically so thought this won't work the first time.
I looked at the application pool and changed it to use 32 bit app's (it is a vs2008 app on server 2008 64),i cannot enable isapi but i don't know if it's needed.What else,ehm,checked authentication for anonym also ip address was left to any,ah and changed the port (it's not running on 80) and also checked the binding's set to that port and also used 80 port + myport for a test and also 80 alone just to piss me off more.
Let me state here that the same application works perfect on IIS6 with just using the host i want and my port and of course changing the security.
Also the 2008 log is very useful, showing logs of 3 hours ago. So is it something i must do or the admin messed the dns redirection to this machine.
If I have in my db a table called User with name, Id, age fields and I want to get these data and put it in a var as a JSON serialize, then I want to send it to javascript page to reform it as I want . I need to know how to put these data in a var as a JSON, how to read the data in the javascript file (how to deal with each one. for example : array[name]?
which thing is more better to deal with these data in asp.net code then send it in the javascript or to send it to the javascript and then to deal with ?
I have a response object which I want to convert to Json, but somehow I can't, propably beacuse of I cannot the framework too well. I'm trying to convert a anonymous object to json but somehow it doesn't go so well. I would preferably do it in JSON than just make a text/plain result. In my controller: ViewData["json"] = new { Ok = false }; In my view: <%: ViewData["json"] %>
In my js-code (ajax-callback) I get back the following: { Ok = False } Which ain't what I am excepting. I want the { ok : false } or else js doesn't recognize the property in the object as a boolean. Or are there some better way to push out json-data? EDIT I did a method in my controller with a JsonResult instead of Actionresult.
var obj = new { Ok = false, Message = "" }; return Json(obj);
And that's the object I'm pushing out. And like this in js: {"Ok":true,"Message":""} C# 4.0 and Javascript goes along so well
