I have been working on a project to read some data of facebook user walls. So I have researched I need to use json and System.Web.Script.Serialization to extract the required data I suppose. Has anyone have a tidy example of how to get something out of json script?

View 2 RepliesI'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.

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

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 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:

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.
This seems like it would be so simple and fast, but I cannot figure out how to accomplish it in VB since there aren't many bit functions. I want to take a file and append 5 junk bits at the beginning and 3 junk bits at the end. In essence, just add 1 byte to the file, but in the process offset all the current bits so the file is no longer readable.
I just need a very simple encryption/decryption, but it needs to be very fast as well. I try XORing the bytes, but it gets slow with just a 1MB file. Some of the files are going to be close to 10MB.
I have written a simple VB.net application which saves information to an RFID tag. I am now trying to compress my data. The solution I have come up with involves bitwire operation.Basically I store 2 numbers per 1 byte (0-9, 10 being a period, 12 possibly being a negative/positive flag,13,14,15 unused as of yet).The code I am using basically shifts the byte containing a number left, 4 spaces, then 'OR's it against another number.Therefore 12 is now represented as 00010010. The problem i'm having is decompressing. Obviously getting the '1' back is easy, as I just shift right 4, then grab it. I need to append or remove the last 4 bits.My solution after many headaches was to reverse the bit order, shift left 4, then reverse, then tostring it.

I have a main form. In this form there is an option to open other form. TThis second form must return a few values to the main form. When the user click on this 2nd form, to return values, this form hangs up (2nd form hangs up)
But for what I could have known, it continues executing the rest of code that exists after to open form. I want to say that the form dialog (2nd form) is not closed (hangs up) but it the code continues being executed, because I have seen that inserts the data in the database.

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).
parsing a JSON from a URL... Using the Nascar JSON file I am trying to place it into a listview or treeview. Displaying the drivers name, number and current position.
[Code]...
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
