We are developing a webservice for a client. We are not supose to throw SoapExceptions, so instead, we catch every exception server side, and return a custom Exception class.
Public Class Order
...
End Class
[Code]....
The problem now is, that since my webmethod is returning the type [Object]. The wdsl that is generated does not contain the order, or the exception.
I can change the [Object] to [Order] Or [MyException], but only one of them is generated in the wsdl.
I want both the MyException type and the Order type in my wsdl, but i just cant get it working.
I have to send a request to Webservice and I have a working PHP solution, that I have to translate in VB.net

//encode the object in JSON format to communicate with the server.

I'm building a Web Service in VB.NET and I want to answer using JSON.
Currently my answers looks like this

Im working on a silverlight application where a user can create, edit, delete objects. The changes they make are placed in a queue which is processed every 4 minutes. When it is processed, the updates are sent over an async web method call to be saved in a sql database, one at a time. When the first update finishes, the next starts.Im having a problem when a user makes a change and then exits the browser app before the 4 minute timer has expired.Currently the changes are getting lost.Ive built on what the guy working on this before me has done, and explored the Dispose and Finalize methods, trying to start the update process when the factory is being shut down, but that isnt working due to the async nature of the web service calls. I get errors saying needed objects have already been disposed of.
View 1 RepliesI have to return a lot of values back to my windows application from my webService. But how would I return more than just a single string/int/boolean from my WebService to myApplication. How would I return a collection, keyValuePair, or even better, a DataSet? Or is this just imposible?
View 4 RepliesI 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.
I'm new at JSON and i am currently struggling with a problem parsing JSON data in a list of objects.The data that i am trying to parse is generated by the facebook graph api, and looks like this :
{
"100001621071794": {
"id": "100001621071794",
"name": "TEST1",[code].....
I know that this is not an array, because it is missing '[' and ']'. But when i replace the '{' and '}' with '[' and ']' i'm getting an error because of an invlaid matrix.

Finally got to the point of having a work webservice using php and nusoap. I can retrieve values and send. Now what I want to do retrieve multiple values into a data grid, I think. What I want to do is retrieve various messages specific to that user. At the moment I retrieve values individually but as there may be more than one result I assume the datagrid may be the way forward. Now the question is how can I retrieve this information. Currently my data returns in the following format.
name.Text = returnData.name
I have a json object from the facebook api
"comments": {
"count": 2
},
"updated_time": "2012-05-24T02:46:36+0000"
The entire json object is a dynamic object.
I can easily read the value of the updated_time with:
post.updated_time
However this returns the count of items in the collection, not the value of the "count" property in the json object.
post.comments.count
Is it possible to get the value of post.comments.count without it using the "count" keyword?
I should note that the JSON is much larger than this. If there are actually comments there is another collection of the actual comments so something like post.count(0) would not work in that case.
Is there a tool in the toolbox that i can use that replaces checkboxes. i have limited amount of space and checkboxes just keep taking up room. I need the user to select multiple objects like checking multiple checkboxes.

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.
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

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 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 want to know how to get information/text form other objects to a textbox.
