ASMX Call - Returning Response Header As XML Instead Of JSON

Dec 29, 2011

My ASMX call is returning Content-Type = text/xml; charset=utf-8
I am using ASP.NET 3.5 and jQuery.Ajax. Have added these things are per numerous suggestions from Stack Overflow. I have done these things

Done this at web.config
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false"
type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
[Code] .....

But whatever I do, the response header is still of type xml. What part am I missing here?

Javascript - Return JSON From ASP.NET .asmx?

Nov 5, 2009

I have the following test method:Imports System.Web

Imports System.Web.Services
Imports System.Web.Services.Protocols
<WebService(Namespace:="http://tempuri.org/")> _

Asmx Json Serialization Versus Wcf Json Serialization?

Nov 24, 2011

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

Necessary To Set Content-Length In Response Header?

Sep 11, 2009

I'm reviewing some legacy code and I've found a bug that causes the response to sit indefinitely.[code]The problem is that someStoredLength is much larger than the actual size of someByteArray, so the client just sits there waiting for the file download while the browser just spins.I'm contemplating just removing the AddHeader that specifies the content length, because when I do that everything seems to work fine, but I'm worried that I'm not understanding something.Is it ok for me to remove this AddHeader or should I figure out a better way to deal with this problem?

C# - Check If HttpContext.Current.Response Have An Existing Header?

Jun 19, 2012

I was working on a scenario where I have to add header to the Response Header.

I added a Response Header like this:- HttpContext.Current.Response.AddHeader("key1", "value1")

After some functional flow I required to add value to same "key1": HttpContext.Current.Reponse.AddHeader("key1, "value2")

thus value in Response Headers look like this:- key1 : value1, value2

I want to avoid the value2 addition to the same keyword key1.

I tried:-

If HttpContext.Current.Response.Headers("key1") Then
HttpContext.Current.Reponse.AddHeader("key1, "value2")
EndIf

But I got the error: This operation requires IIS integrated pipeline mode at HttpContext.Current.Response.Headers("key1")

I have IIS6 running. This [URL] says that it doestn't works if its not IIS7

Javascript - Response.Redirect AFTER Call To JS Alert Or Confirm?

I am working on a VB.NET web application. When someone successfully changes their password I want to show a popup message that lets them know it was changed successfully. After they click OK I want to redirect them to the main page. Code looks like this:

Response.Redirect("MainPage.aspx")

Why does the redirect happen and the alert popup never displays?

ASP.NET MVC AJAX Returning New Page On Simple Call

Jul 15, 2009

I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.

My stripped down View (of type IEnumerable(Of MyTable)):

<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>

[Code]....

What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.

Twitter Json - Unable To Convert To Jobject Or Jarray Using Json.net / Javascriptserializer?

May 9, 2012

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'm willing to use an additional DLL file if needed.

Using JSON.NET To Parse JSON Generated Through PHP?

Mar 2, 2010

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).
