We have a asp.net page where the user is allowed to upload a file. This file is then sent on to a back end system via a wcf services. Currently we read the file into a byte array and then send an object into the wcf service where the byte array is a property. This works fine, but we are wondering if there is a more efficient way to do it?
View 1 RepliesI have a simple Web Service method defined as:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string MyWebMethod(string foo, string bar)
{
// DataContractJsonSerializer to deserialize foo and bar to
// their respective FooClass and BarClass objects.
return "{"Message":"Everything is a-ok!"}";
}
I'll call it from the client via:
var myParams = { "foo":{"name":"Bob Smith", "age":50},"bar":{"color":"blue","size":"large","quantity":2} };
$.ajax({
type: 'POST',
url: 'https://mydomain.com/WebServices/TestSvc.asmx/MyWebMethod',
data: JSON.stringify(myParams),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (response, status) {
alert('Yay!');
},
error: function (xhr, err) {
alert('Boo-urns!');
}
});
However, this yields the following error (a breakpoint on the first line in MyWebMethod() is never hit):
{"Message":"No parameterless

I'd like to pass in two string parameters and use DataContractJsonSerializer to write new Foo and Bar objects. Am I missing something?
I'm running a WebMethod when a user clicks a link and I want the service method to have access to the clients SessionID but when I try to initialise a new string it returns a null value.
So to clarify(an example):
[WebMethod]
public string myMethod()
{
string s = Session.SessionID.ToString();
//rest of method here...
}
string s is returning null value. The code works fine on a postback and the method works without SessionID but I really want/need to be able to use a callback and need to be able to use the SessionID
I want to develop a windows service which will be accepting a datatable from an aspx page. Both the windows service and the website are hosted on same machine.

I'm calling an external Web service that requires a certificate to be passed. This works perfectly fine for a stand-alone Windows Forms application, but when I attempt to do the exact same thing through an ASP.NET Web Application, it throws the following error:
"No connection could be made because the target machine actively refused it"
I found this MS article that describes what appears to be the exact issue I'm having, but it only applies to .NET 1.0:

I'm using .NET 3.5, so surely it must be fixed by now!
I've attempted to change permissions on the certificate and fooled around with the app pool identity, but nothing seems to work.

I have a number saved in session and am using it in a bunch of pages right now, and I was wondering if I could somehow access this session in my WebService.asmx file? It would be great since then that way I can fix my auto complete extender. I know I can use contextKey, but I am using that contextKey for something else. If session isn't possible in web service, then is it possible to use two contextkeys in auto complete extender, and how?
View 1 RepliesI'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array.
Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough,
I have an containing a list of divs that jQuery turns into progress bars. On .ready, I build a list of all of these progress bars and for each one, call a webservice that gets a value indicating how full the progress bar should be. In order to do this, I need to pass the ID of the div to the web service.
Because the divs are inside a ListView, I manually set the id to be id="completionbar_<%# Eval("MilestoneID") %>"
However, when I pass this id into my web service, it comes up as "undefined" every time. When I view the source, it looks like it's set correctly.
Here's the jQuery that calls my web service:
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$(".MilestoneCompletion").progressbar({ value: 0 });
$.each($(".MilestoneCompletion"), function(index, barDiv) {
[Code].....
I'm thinking maybe the script is executing before the DIV id is set by the ListView databind?
I am working on Tenant module that has to display following fileds, Tenant Id, Tenant Desc, Contact Person, Contact Phone. In the DB, these are designed as two separate tables - Tenant and Contact. Tenant table has Tenant Id, tenant Desc and Contact Id . Contact table has all the contact related properties. I am using EF as DAL.
To make my system loosely coupled, I have created a repository pattern to talk to EF entities. Also, for validation I am using service layer.
My repository layer has two interfaces and classes corresponding to Tenant and Contact.
public interface ITenantRepository : IRepository<Tenant> // IRepository<T> is a generic interface for CRUD operations
{
Tenant Get(int id);
IEnumerable<Tenanr> List() ;

I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.
We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission.
The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n.

What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX
I'm running an ASP page that is using a WCF client to get some data. How can I set/pass the Network Credentials (of the user that performed the request, not the .net pool thread) on the WCF client so the WCF service will be able to perform impersonation using these credentials ?
View 1 RepliesI have a custom class declared as follows (in vb.net)
<Serializable()> _ Public
Class NumInfo Public n As String
Public f As Integer Public fc As
char() Public t As Integer
[Code]....
What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button.
I have a web service called service1. Is it possible to pass the parameter related to the service to a class library so for e.g.
Service1.service ws = new Service1.service();
Service1.UserDetails ud = null;
now if I call a method that exists in a class and pass ud. Cam i do that because I am trying to do this and I am getting an error. Do i need to add a web
reference to this service in the class library My method call is like this
authenticateUser.Authenticate(ud, UserName);
and in the class libary I have
public void Authenticate( Service1.UserDetails ud , string UserName)
{

I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx

Imports System.ComponentModel
Public Class CustomValidate
Inherits System.Web.Services.WebService
'ACCESS VIA JSON
<System.Web.Services.WebMethod()> _

Return True
End Function
End Class
Javascript: JQuery JSON
function isDates(source, arguments) {
var isValidDate;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CustomValidate.asmx/AJAX_Test",
data: '{date1: "' + arguments.Value + '"}',
dataType: "json",
async: false,
success: function(result) {
isValidDate = result;
},
error: function(httpRequest, textStatus, errorThrown) {
alert("status=" + textStatus + ",error=" + errorThrown);
}
});
arguments.IsValid = isValidDate;
}
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.

I need to force SSL when going to the final checkout page (for example from default.aspx to checkout.aspx).
I need to pass variables to this check out page and tried to use server.transfer(https://www.mydomain.com/checkout.aspx). I then use previous page .Fincontrol to read text box and label name to this check out page. If I only do the server.transfer("~/checkout.aspx") then my I can read all vakues of my controls from the passing default.aspx page.
But when I force https:// then I cannot read the control values from default.aspx page.
Please give me some tips on how to get control values to the https:// destination page or if you have another tips on how to do it the right way, please let me know.
