Why does that happen and how can I stop the error message from appearing?
I have an assigment where I must send queries to the database and the returns data. I would like to convert that data to a json and then use it with jQuery
My idea is make an array (żarrayList?) and then convert it to json.
How can i use json with asp.net vb? I'm not allowed to use a webservice yet
I need to return json data from the server, which can be used on the client side and I am not sure the best way to format the json data.
So basically, What is the best way to format the json data to include:
key/value pairs so they can be looped through at clientside (loop via jquery), a count of the number of id/value pairs which can be used at clientside for other purposes (used via jquery).

my problem is that my company does not want to serve up the .json MIME type, so I have to use ASP.NET to fetch the JSON file from the file server. Currently I have jQuery that does a getJSON and traverses the JSON object to build certain elements of the page. Is there a way I can use ASP.NET (VB) to give the object to my jQuery script after I fetch it?
View 1 Replies[URL] Using this I have managed to use Server Side Web Methods to perform actions with AJAX.In most instances, I just need it to do stuff (save things to a database for example) so don't need to do anything with the response, but now I've come across a situation where I do, and I can't work it out!The Web Method returns a JSON object, which looks like this:
{"d":"[{"validDetails":"True","lateAlert":"","LoginResponse":"Logging in Jamie at 16:53 please wait"}]"}
This is the output shown from Firebug. I am not sure what the 's are, but bear with it...The AJAX call and attempt at outputting this response is:
$("form").on("submit", function () {
var LogonObject = new Object;
LogonObject.password = $('#password').val();
[code]....
And several other variations from info I have found on Google and SO, but it seems to treat the results variable as a string, not an array, and the output I get on the alerts is each individual character, ie;
[, {, ", v, a, l, i, d, D... etc
So I wondered if results needed to be converted to JSON again (though I don't know why) so I tried
results = $.parseJSON(data.d)
But that didn't work either.
EDIT, the code which generates the response (missing out tons of logic, but this is the important bit):
Public Class OutputObject
Public validDetails, lateAlert, LoginResponse As String 'content of JSON output'
End Class

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?

I am creating a simple VB.NET WebBrowser to automate and simplify navigation of a web site. However on certain pages i get the following popup message. This is telling me about an error which is on the Web Site itself and thus out of my control.

The application is for personal use, so auto-clicking yes would be an acceptable option.

For testing purposes, I write a lot of alerts and error messages into a .txt file (some 15 entries per second). At the end of the day, the txt file becomes very large. I am now getting confronted with data loss in my application (threads indicated as being busy). Could it be that my entries in the Log.txt are slowing down my application to the point that the latter becomes unstable ?
View 2 RepliesHow 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).
