Web Development Discussion Boards

Hi everyone! In my SMS application, I need to send a list of phone numbers to a script on a web sever to be sent to the recipients

Recipients will be selected from a database on the client machine. The number of recipients is over 5000. Additionally, this can rise to over 10,000 some time to come.

Being a newbie in web programming, I would like to know how I can send all these phone numbers to the server. I read that GET method can send small amount of data with the POST method capable of sending large data. However, I do not know the limit to the POST method. Please help. Thanks in advance.

Looks like it is 8Mb max size for the POST method.

I'm a bit confused.

Do I understand that the client machine will be sending up to 5,000 phone numbers to a web server which will process messages to those recipients?

This is not a web page is it?

How about developing a webservice and send the data to the server using that? I don't of any limits on the size of a webservice data payload. You could also batch the phone numbers into chunks of 500 and call the webservice multiple times.

I just don't understand your problem. It's early monday morning and I'm just having my first cup of coffee. Cool | :cool:

It's not a web application David. It's a database application programmed in C# WinForm that does not usually require web access.

The only time web access is required is when a message needs to be sent to members enrolled on the system. Then I will need to send the phone numbers to a php script on a website that will send the message.

My problem now is how I can send all the phone numbers to the script at once. In this case the script will be called only once without calling it multiple times. That's the whole problem David. Any suggestion? Thanks.

If the list of phone numbers contains only the phone numbers (no delimiters, no other fancy characters) and is a simple newline-delimited text file, then it should be no problem sending it to the server, even with a range of phone numbers much, much larger than what you're talking about (I've actually created a text file with 50,000 numbers, in the format: +40 123 456 789. It took 840kb).

I also think you can set the maximum post size in the server's php.ini configuration file, if of course, you have access to it

EDIT: Yep, found it (in php.ini file), it's this:

post_max_size = 8M

Set this to whatever you need to (even though cases when you'd have to go beyond 8MB are quite rare)

Thank you for the clarification. I understand the problem now.

Based on the replies you have received, it appears that you should be able to post the data to the web server without any problems.

I'm getting the feeling that you don't have control over the website which processes the phone numbers and messages.

So, is the problem that you don't know how to create a POST request for the website?

Sorry if I'm not more helpful. Still trying to wrap my head around it.

I think you should worry about the post size last.

Sounds like there is already a mechanism for submitting phone numbers to the web server, if so, you should get the API for it, and write code that packages your numbers and transmits it as per the API indicates.

If there is not a mechanism, then you need to write one first, and make sure some one like me can't use the mechanism to capture your phone numbers, and then turn around and blast a phoney message to your subscribers.

Your post size is the least of your worries.

I folks:

I know that CGI is jurassic and before all of you call me lunatic, I must say that this question is only for EDUCATIONAL PURPOSES (in real cases I use JSP).

I'm trying to code a "Hello World" CGI in Java, and I'm unsucessful.

So I try the same job in C#. Both programs (C# and Java) are totally equal (line by line). The C# works and the Java don't.

Here's the code in C#:

XML

namespace CGI_CSharp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Content-Type: text/html\n"); // the extra "\n" is needed
            Console.WriteLine("<html>");
            Console.WriteLine("<head>");
            Console.WriteLine("<title>CGI - C#</title>");
            Console.WriteLine("</head>");
            Console.WriteLine("<body>");

            Console.WriteLine("<h1>Hello World !</h1>");

            Console.WriteLine("</body>");
            Console.WriteLine("<html>");
        }
    }
}

In the browser URL I wrote: http://localhost/CGI_CSharp.exe and BINGO! The C# code WORKS !

Now the same code in Java:

XML

public class CGI_Java
{
    public static void main(String[] args)
    {
        System.out.println ("Content-Type: text/html\n");
        System.out.println ("<html>");
        System.out.println ("<head>");
        System.out.println ("<title>CGI - Java</title>");
        System.out.println ("</head>");
        System.out.println ("<body>");

        System.out.println ("<h1>Hello World !</h1>");

        System.out.println ("</body>");
        System.out.println ("</html>");
    }
}

Now I've tried the URL:

http://localhost/java.exe%20CGI_Java

(as you know, the %20 is the space => (http://localhost/java.exe CGI_Java)

I get:

HTTP 404.0 - Not Found

So, I try again, now with a batch file (CGI_Java.bat) with a single line of text:

java.exe CGI_Java (content of the CGI_Java.bat)

And now, I try the URL:

http://localhost&/CGI_Java.bat

Now the browser shows:

C:\inetpub\wwwroot>java.exe CGI_Java

This is the prompt followed by the command I wrote in the batch file.

Can someone help me?

Thanks in advance.

With the batch file maybe redirecting the output?
http://www.robvanderwoude.com/battech_redirection.php[^]

Interesting topic, I imagine you are getting the 404 because you are expecting the CGI_Java to be passed as a command line argument. I don't think the browser works that way. Have never tried anything like this but wonder if any querystring variables would be passed as command args like...
http://localhost/java.exe?CGI_Java Unsure | :~

???

Its needs to take the info the customer gives and send it to the company e-mail. there is an issue doing so and i dont know y so if anyone can help a.s.a.p. thank you.

Website in this code i typed as an example. its not the site im working on.

Though you have not shared much on what were you trying to do and what the XML looks like, based on the stack trace it looks like there is duplicate nodes name.

Read all about it here: MSDN: Deserialization Problems Caused by Duplicate Node Names[^]

Find the duplicate class and remove it. Similar thing happened[^] with him and he too removed the duplicate.

Good Day Guys

This is an MVC , JQuery, KNockout.js Question.

i have a Controller Action that is being Defined like this

C#

[HttpGet]
        public JsonResult SearchCars(string searchString)
        {

            string[] searchTerms = (searchString).ToUpper().Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);

            string[] searchTermSounds = new string[searchTerms.Length];
 
            var list = (from r in Cache.CarSearchItems
                       select new Lightstone.UI.Web.LaceWebUI.Models.CarItem(r, searchTerms, searchTermSounds)).ToList();

            var list1 = list.Distinct()
                             .Take(5)
                             .OrderByDescending(l => l.Hits).ToList();

            return Json(list1, JsonRequestBehavior.AllowGet);
        }

and i have a Jquery function that gets fired onkey up event is fired in a textbox like this

JavaScript

$(function () {
    $("#txtSearchString").keyup(function () {

        $("#txtSearchString").queue(function 
            () {
            var _this = $(this);
            _this.addClass("newcolor");
            _this.dequeue();
        });


        if ($("#txtSearchString").val().length >= 3) {
            var data = {}
            data.searchString = $("#txtSearchString").val();
            alert("Retrieving Data");
        
            $.getJSON("/Cars/SearchCars", data, function (result) {
                //Autocomplete binding
                var viewModel = null;

                viewModel =
                 { 
                     SearchOptions: ko.observableArray(result) // These are the initial options 
                 }
                alert("Done Retrieving Data");

                if (viewModel == null || viewModel == undefined) {
                    alert("The ViewModel is null or Undefined");
                 
                    alert("Done with the View Model");
                }
                else {
                    ko.applyBindings(viewModel);
                    alert("THe View Model is no Null");
                }
              


            });

        }

    })
});

dont mind my alerts i use them to check the code reaches the place that i want it to reach. I can get the Jason the first time and this is the order of my alerts

JavaScript

 alert("Retrieving Data");
 alert("Done Retrieving Data");
alert("THe View Model is no Null");

and then i bind the data to my HTML view as depicted below

C#

<table  id="tblsearchresults"  data-bind="foreach:SearchOptions"  class="auto-style1">
        <tr>
            <td rowspan="5">
                <img data-bind="attr: {src: Url}" class="" />
            </td>
            <td>Make:</td>
            <td>
                <div data-bind="text: Make">
                </div>
            </td>
            <td> </td>
        </tr>
        <tr>
            <td>Model:</td>
            <td>
                <div data-bind="text: Model">
                </div>
            </td>
            <td> </td>
        </tr>
        <tr>
            <td>Year:</td>
            <td>
                <div data-bind="text: Year">
                </div>
            </td>
            <td> <a data-bind="attr: { href: UrlRedirect }">
                View Report</a>

            </td>
        </tr>
        <tr>
            <td> </td>
            <td> </td>
            <td> </td>
        </tr>
        <tr>
            <td> </td>
            <td> </td>
            <td> </td>
        </tr>
    </table>

and i see the data when i search for the first time and the images appears nicely and then the Problem start when i change my search string lets say i now type "FORD"

C#

<input id="txtSearchString" name="txtSearchString" class="searchText" />

and it does not return results, when i look at the F12 debugging tool in chrome it point to my JavaScript in the following line

C#

ko.applyBindings(viewModel);

and in my

C#

The Problem happens when Knockout tries to Bind the ViewModel to the same node multiple times. seting the viewmodel to null will not work , so to resolve this i explicidly binded the tablelement, and after that i clear the node before i bind a Viewmodel

JavaScript

ko.cleanNode(document.getElementById("tblsearchresults"));

Need help in writing a java soap web service with soap header.

.net client should pass the user name and password in soap header to java web service.

on authentication the function should be accessible to .net client.

How can I achieve this please help me.

Please do not post the same question in multiple forums. I have already responded this in the Java forum.

One of these days I'm going to think of a really clever signature.

i want to know how to use tracing and when to use it , i want to know why it is found in visual studio ?

As mentioned in MSDN, Tracing: These are statements that are intended to help track the flow of control and state of the program as it’s executing.  Imagine running a debugger, stepping along through code and checking the values of key variables in the Watch window. Tracing statements are intended to replicate that experience in cases where you can’t attach a debugger. They should ideally provide enough context that you can see which path is taken at each control point in the application and sort of follow along in the code from reading the trace statements. Tracing is enabled when the TRACE preprocessor symbol is defined at compile time, and can be in both release and debug builds. (By default, Visual Studio defines TRACE in both debug and release builds, but you can of course change this.)

About how to use it, follow these: MSDN: Configuring Tracing[^]

Actually, all you want to know about tracing: MSDN: Tracing[^]

Also go through this MSDN Support article: MSDN Support: How to trace and debug in Visual C#[^]

Sandeep Mewara
[My last article]: Server side Delimiters in ASP.NET[^]

Think Sandeep addressed the "how to" pretty well... as to why... well, because it works very well, I've found it particularly useful when troubleshooting bugs in multi-threaded applications. Subtle bugs are sometimes almost impossible to find with other methods (such as breakpoints), so tracing gives you the ability to add debug code that will be printed and can be analyzed after the fact (similar to a log file).

Good Day All

i have a Strange issue here using the knockout lib. i have setup the Javascript like this

JavaScript

$(function () {
    $("#lstSearchOptions").change(function () {

        var data = {}
        data.id = $("#lstSearchOptions option:selected").val();
        $.getJSON("/Cars/SearchDetails", data, function (result) {
            var model = { 
                SearchOptionsR: ko.observableArray(result)
            } 
            ko.applyBindings(model, document.getElementById("tblsearchresults"));

        });
         
        $("#lstSearchOptions").blur(function () {
            $("#lstSearchOptions").hide("fast");
        });
    });  
});

and my HTML is defined like this

Spoted in Daniweb-- Sorry to rant. I hate websites. They are just wierd. They don't behave like normal code.

As far as I can tell REST is a methodology or an archecture. Is it a real tangable thing? I mean, can you look at a back-end code and determine if it is REST or not REST? How do you communicate with a WCF RESTful service? Are all WCF services RESTful?
