WCF Vs ASPX Webmethods Vs ASMX Webmethods?
Dec 3, 2010The intent is to create a set of web services that people can reuse. These services mostly interact with a backend DB creating, retreiving and processing data. We want to expose services so that people can use to create data mashups and other applications.End users are webpages that can be within our domain or outside our domain. For pages outside the domain we plan to release widgets that would be configured to retreive and display the data.
One requirement - application should be extremely scalable in terms of the number of users it can handle.Our code base is .net and we are looking at ASPX webmethods (or ASHX), ASMX webmethods and WCF (starting to read up on WCF). In terms of security/access I found that maintaining sessionid, memberships is doable in all three. WCF seems a bit complicated to setup. I could not immediately see the value of asmx when we can get all done just using a webmethod in aspx (with a little tweaking). Also, assuming that with the ASP.NET MVC2 I might be able to get clean urls as well for these webmethods.QuestionsWhich one will be the most effective in terms of performance and scalability? Any reason why I should choose WCF or ASMX?
EDIT I kind of understand that WCF is the way to go. Just to understand the evolution of the technologies it would be good if someone can throw light on why a aspx webmethod is different from an asmx when similar things (apart from discovery) can be accomplished by both. The aspx webmethods can be made to return data in other formats (plaintext, json). Also, it seems that we can build restful services using ashx.
Best Practice When Using WebMethods And Session?
May 15, 2010I want to reduce postback in one of my application page and use ajax instead. I used the WebMethod to do so.. I have a static WebMethod that needs to access the session variables and modify. and on the client side, i am calling this method using jQuery. I tried accessing the session as follows:
[WebMethod]
public static void TestWebMethod()
{
[code]...
The values are displayed correctly and seems to work.. but i would like to know if this practice is allowed as the method is a static methods and would like to know how it will behave if multiple people access the application.I would also like to know how developers do these kind of tasks in ASP if this is not the right method.
Webservice - Can It Have Two Webmethods With Same Name But Differnent Paramat
Nov 22, 2010I have a webservice (using asp.net VS 2008).If I have two webmethods with same name but different input parameters and same output parameters. Just like given below. Can't I have two webmethods with same name with different parameters?
Code:
[WebMethod]
public Portfolio GenerateData(string As_of_Date, bool PortfolioLoadfromArchive)
{
Portfolio aPortfolio = null;
[code]...
Both TestProj.WebServices.Portfolio GenerateData(System.String) and TestProj.WebServices.Portfolio GenerateData(System.String, Boolean) use the message name 'GenerateData'. Use the MessageName property of the WebMethod custom attribute to specify unique message names for the methods.
Call Javascript Function From WebMethods?
Jan 25, 2011I am using PageMethods in asp.net. In code behind i have written a method which should call a javascript function for each loop & should come back & continue the loop.Is it possible?
[WebMethod]
public static void GetStatus()
{
for (int i = 0; i < 10; i++)
{
System.Threading.Thread.Sleep(500);
//Call javascript function
}
}
C# - JQuery / ASCX And Webmethods Not Seem To Be Working?
Apr 24, 2010I have a cascading dropdown (3 of them) Type, Categories and Sub Categories. Type loads first and upon selection of Type, Category load and selection of Category, Sub Category loads. Also i have 2 buttons, "Add Category" and "Add Sub Category" Upon clicking on these buttons, i call a JQuery Modal Form to add them. I use Webmethod in code behind to add them to database
This works perfectly in ASPX page.
Since I need use this in 3-4 pages, i thought of making the above as User control (ASCX). When i try to use this in a webpage, the webmethods in ASCX don't get called.
Controlling Which WebMethods Get Exposed Externally In A WebService?
Jan 11, 2010I couldn't think of a decent title, so let me first apologize for that. I have a WebService (call it A) written for my app so I can take advantage of ASP.NET 3.5 AJAX features. I use the generated JavaScript proxy to make AJAX calls.As a side effect, WebService A is exposed for anyone to add as a reference to another project, which is great, except I don't want certain WebMethods to be available to external applications (in the same domain, BTW).So I've got two questions:Is there a way to control the exposure of WebMethods in WebService A?
If there isn't, I'm thinking I'll just add a separate WebService (B) that exposes the WebMethods I need from WebService A. But then,How can I prevent other applications from referencing WebService A while still allowing the application it originates in to access it?If that's not possible, I'm not really worried about it. The apps are all intranet-only, I just don't want the WebServices to be abused.Also, there is a similar question here already without any good anwers. The asker describes almost the same situation I'm in: [URL]
Calling WebMethods / WebService Using Jquery Is Blocking?
Apr 6, 2010I'm generating a file on the server which takes some time. For this, I have a hidden iframe which I then set the .src attribute to an aspx file i.e iframe.src = "/downloadFile.aspx"While this is taking place, I'd like to have a call to a web service return the progress. To do this, I thought I could use window.setInterval or window.setTimeout but Javascript seems to be blocked as soon as I set the iframe src attribute.Does anyone know how to get around this or perhaps try a different approach?I have also tried handlers, but the request never gets to the server so I'm assuming is a browser/javascript issue.
//Function that gets the file
function GetFile() {
setTimeout(GetProgress, 1000);
var iframe = document.createElement("iframe");

Invoking WebMethods With XmlHttpRequest And Pure JavaScript?
Jun 22, 2010I have what should be a relatively simple task that's frankly got me stumped. I've researched it until my brain is fried, and now I'm puntingHere's the scenario:I have an ASPX page (Q2.aspx) that is decorated with the WebService,WebServiceBinding, and ScriptService attributes. That page contains a method, GetAllContacts, that is decorated with the WebMethodattribute and returns a string containing JSON data. (For what it's worth, the pageitself contains no other controls or functionality.)I have an HTML page that contains JavaScript which uses the XmlHttpRequestobject to invoke the GetAllContacts WebMethod on the ASPX page and transformthe JSON data into an HTML table. I have verified that my Web.Config file contains the appropriate protocol handlersfor HttpGet and HttpPut in the WebServices section under System.Web.webServices.
I have verified that my Web.Config file contains the ScriptModule entry under theSystem.webServer.modules section, and that it matches the appropriate documentation.
However, when I view the HTML page in a browser, the following occur:The web request goes through, but the results are for the unprocessed HTML from the ASPX page.The GetAllContacts method is never invoked, as evidenced by setting a breakpoint in its code.The code to invoke the Web service, however, is invoked, and the JavaScript callbackfunction that is invoked upon request completion is properly invoked.
It appears that the JavaScript code is largely set up correctly, but for some reason that is completely escaping me at this point, the HTML page will simply not execute the WebMethod on the ASPX page, and simply returns the page as though it were a plain HTML GET request. Clearly, an HTML document can't be evaluated by JavaScript's eval function, which brings me to my problem. (Also note that the JSON data appears nowhere in the HTML that's returned.)I am, frankly, baffled. I've looked at dozens of Microsoft articles, StackOverflow posts, CodeProject articles, and who knows what else. My code looks like it's okay. But I know better. I'm missing something simple, stupid, and obvious. I just need someone to point it out to me.Below you'll find the ASPX page code and the HTML code, in the hope that they'll shed some light.ASPX Code

C# - Exchange Session Variables Between Webmethods In Webservices?
Sep 14, 2010I have the following code to store session variable in one webmethod and retrieve it in other webmethod but the value displays null when i try to retrieve it.

{
Session["Company_Name"] = businessname;
SqlConnection con = new SqlConnection();

public bool addresslisting()
{
string companyname = (string)Session["Company_Name"];// this particular value is displaying null

Globally Handling Exceptions In Static Aspx [WebMethods]
Mar 16, 2011The default behavior of a [WebMethod] attributed static method on an aspx page is to return the error to the caller. We are accessing these methods using json, and the only way we have found of capturing exceptions is either a try/catch in every webmethod on the site or using a javascript callback with the error (which has the unacceptable downside of exposing the error to the client).
Is there any way to globally handle these exceptions using the HealthMonitoring setup in ASP.NET?

How To Invoke A JavaScript Through A Thread
Feb 23, 2011I have a thread that runs querying a DB and returning some values. If this values satisfyes a condition, I want to raise a message box (javascript alert) for the client side.
In my system, users can post some tasks in DB, and the thread is going to constantly query the database to check if user has things to do. If user has, the system must alert him through a message box.
I've done javascripts invokings with ClientScript.RegisterStartupScript, and Attributes.Add for buttons. But now I want to call the javascript functions (wich will alert the user that he has things to do) from the midle of a sub (that is executed in a thread), without a submit, load or click event. How can I do it?

and it's been answered! My only problem is I don't really understand the solution. How does one Invoke the control when setting the property.
I have a label control but there doesn't seem to be an Invoke property/method on it.
I tried this...
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(Label1);
PropertyDescriptor myProperty = properties.Find("Text", false);
myProperty.SetValue(Label1, "my value");
but that seemed to be the same as
label1.text = "my value"

How To Invoke Code Within A Web App That Isn't Externally Open
Sep 3, 2010for example, you are caching data within your ASP.NET web app that isn't often updated. You have another process running outside of the app which ocassionally updates this data, when you do this you would like the cached data to be cleared immediately so that the next request picks up the new data straight away.The caching service is running in the context of your web app and not externally - what is a good method of calling into the web app to get it to update the cache?
You could of course, just hack a page or web service together called ClearTheCache that does it. This can then be called by your other process. Of course you don't want this process to be externally useable or visible on your web app, so perhaps you could then check that incoming requests to this page are calling localhost, if not throw a 404. Is this acceptable? Could this be spoofed at all (for instance if you used HttpApplication.Request.Url.Host)?
I can think of many different ways to go about this, mainly revolving around creating a page or web service and limiting requests to it somehow, but I'm not sure any are particularly elegant. Neither do I like the idea of the web app routinely polling out to another service to check if it needs to execute something, I'd really like a PUSH solution.Note: The caching scenario is just an example, I could use out-of-process caching here if needed. The question is really concentrating on invoking code, for any given reason, within a web app externally but in a controlled context.
