JavaScript - Server To Server Connection (with Clients) ?

Ok my lab6 at

http://opentech.durhamcollege.ca/~in...rittains/labs/

is conflicting with my interface as it is php...

is there a better way for me to do this that will allow it to not conflict?

PHP Code:
<?php $title = "Lab6"; include "head.php"; ?>

table, td, th {

The assignment was supposed to be done in PHP. But I want to know if there is a better way either way. Like can I use AJAX instead of PHP to do that? or change the way the PHP works... something anything...

if the proxy is an intermediary between the client and the requested url
could that url be sent to two different clients in response?
so in stead of this

[client]<-->[proxy]<-->[website]

it would be this

[client1]<-->[proxy]<-->[website]
.................. /
...........[client2]

meaning if [client1] requests "google.com" on the proxy server
the proxy server will request "google.com" and send it back to [client1]
as well as [client2]

it would just be url sharing between two people, like a real time delicious.com

heya, ^.^ sorry if this is in the wrong section, im new here so i wasn't sure as it concerns both java and php, so basically i've made a website that pings a server address when someone views the site, but currently it will ping every time you f5 or refresh ect, what i need it to do is only ping once every 2mins, store the value for when its not being pinged to be displayed, now i got told this could be done in javascript?, but my knowledge of javascript is very minimal,

i also got told that
"var m_pingDomain_timer = setInterval(dopingDomain, 120);"

may have something to do with it?, and help /code or pointers in the right direction would be a great help ,

il leave you with the PHP code so you can look over below

Code:

        <tr>
          <td class="SEBody1">
			<?php
			// Function to check response time
				error_reporting(0);
				function pingDomain($domain)
				{
					$starttime = microtime(true);
					$file      = fsockopen ($domain, 80, $errno, $errstr, 10);
					$stoptime  = microtime(true);
					$status    = 0;

					if (!$file) $status = -1;  // Site is down
					else {
						fclose($file);
						$status = ($stoptime - $starttime) * 1000;
						$status = floor($status);
						}
					return $status;
				}
				
				echo '<table>';
					$domainbase ="google.com";
					$status = pingDomain($domainbase);
					if ($status != -1) echo "<img src='img/shard_status_online.png' width='18' height='18' alt='Online' />Online";
					else  echo "<img src='img/shard_status_offline.png' width='18' height='18' alt='Offline' />Offline";
		
				echo '</table>';
		 ?>	
		  </td>
          <td class="SEBody1">로그인</td>
          <td class="SEBody1">Login</td>
          <td class="SEBody1">
			<?php 
				if ($status !=-1) echo "$status ms";
				else echo "0 ms";
			?>
	</td>
        </tr>

I have a google blogger site on which I want to run a PHP script. The problem is that blogger doesn't have a PHP interpreter.

So I was thinking, can I run the php file on a remote server that supports php, and load the result in a div in blogger?

Thx!

Hi,
I am hosting my website in free server (freehostia.com) and i am using joomla1.5 . I want to parse RSS from my other websites. Joomla does it with its modules. But the server do not allow outbound HTTP request, hence i had use rss-to-javascript website to parse RSS feeds. It parses well but there is its advertisement below the feed (which i think is nonsense).

The link it provides is in the format of
<script src="http://somethin.com/somdfile.php?parse=.."></script>

when i put the link in my browser i see following
document.write("string of my parsed xml file with advertisement at end");

What i want to do is get the sting of above line and edit it to chop off the end advertisement.

if there was any method to load that output sting in any variable, the task would had been completed.

If anybody knows how to do it, please help me.

I must make clear that I am not a javascript programmer; I am simply trying to get this script to work on my website. It functions perfectly locally (with all browsers), but after uploading to my website, it shows the controls at the top, but not the content.

Below is the code for the FreeMind Flash Browser which can be found he http://freemind.sourceforge.net/wiki.../Flash_browser

It requires 2 additional files, flashobject.js and visorFreemind.swf plus the FreeMind file (*.mm) that stores the content. The FreeMind file that has the content displays perfectly on localhost, but not on the website. I have all of these files in the same directory and have double checked everything, but it still doesn't function on my website. I have other flash files and scripts on the same website in other pages that function perfectly.

Hello again...
I have written a custom slideshow script which gets the images from an array...
The script will change the src of a img, which is a fullscreen background.

Now here's the problem, I've been trying to write a function where can define a folder "gallery\test\", and then get all image files in that folder and repopulate the slideshow array.

So, is there a way to scan folders?

I've searched around and found some solutions where PHP is used, but i really want to keep this pure js, if possible (?)

Thanks,

I have trying to save an update the xml file which is there in same folder in which HTML page is there. In HTMl page i have written javascript code to Save and Update XML on server.The code is like this

Code:

function Save()
{ 
var xmlDoc= new ActiveXObject("MSXML.DOMDocument")
xmlDoc.async="false"
xmlDoc.load("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml") 

//..code to modify xmlDoc

xmlDoc.save ("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml")
xmlDoc = null;
alert('Details saved'); 
}

When i am accessing HTMl page on server from client and this function is called error 'Parameter is incorrect' is showing on line

Code:

xmlDoc.save ("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml")

Note: xmlDoc.load("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml") is working fine.

The save is working fine in local but not when on server and request from client.

Kindly suggest me the possible solution to it.

Hey.

I'm currently looking for a countdown script, which is based on the server's time. I've only found scripts, that's based on the local computer's time, which means the output of the script changes, when the time on the computer is changed.

And I want to make a public announcement which counts down to something - and should output the same at every person.

I'm not that familiar with JavaScript, I know some jQuery - if anyone can supply any links or can help me with this, I'd appreciate it.

Hello,

I'm building a very simple app that relies on a remote server. I will use this app on many websites, so I decided to store it on one server (I have control of the remote server in question).

I need to make sure that this server is up and running, so in the case it's not I can use a fallback.

Would it be a client-side approach? A server-side approach? My guess is to use a js snippet to do the job. If I'm correct, I'll probably use jquery to perfom the task.

Regards,

-jj.

Hi,

I am trying to follow this tutorial and make a login feature for my apphttp://code.google.com/webtoolkit/do...unication.html to use GWT's remote procedure calls (RPC) to have server client communication to eventually make a web app that talks to a database.

I thought I followed it exactly but when the async returns it fails and returns an exception: "com.google.gwt.user.client.rpc.InvocationException"

Can someone please take a look at the client code, it must be something stupid that I am doing wrong. Thanks

Here's the code:

In the calling client class:
Code:

private MyServiceAsync svc = (MyServiceAsync) GWT.create(MyService.class);

((ServiceDefTarget)svc).setServiceEntryPoint(GWT.getModuleBaseURL());

//loginButtonListener
btnDBLogin.addClickHandler(new ClickHandler() {
   public void onClick(ClickEvent event) {
      svc.checkLogin(txtUsername.getText(),txtPassword.getText(), new AsyncCallback<Boolean>() {
			        	       
	 public void onSuccess(Boolean result) {

	    if (result.booleanValue() == true) {
		System.out.println("Works");
			        	               
             }
             else {
		 System.out.println("Invalid UserName or Password");
	     }
	 }
	 public void onFailure(Throwable ex) {
	    System.out.println("FAILU  " + ex.toString());
          }
    });//end checkLogin
  }//end onCLICK
});//endbtnlistener

MyService.java (client interface)
Code:

package com.rob.projects.client;

import com.google.gwt.user.client.rpc.RemoteService;
 
public interface MyService  extends RemoteService {
    public Boolean checkLogin(String userName, String password);
    
}

MyServiceImpl.java (server code)
Code:

package com.rob.projects.server;

import com.rob.projects.client.MyService;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
 
public class MyServiceImpl extends RemoteServiceServlet implements MyService {
 
private static final long serialVersionUID = 1L;

public Boolean checkLogin(String userName, String password) {
    System.out.println(userName);
    if (userName.equalsIgnoreCase("bingo")) { // Check the database
       return true;
    } 
    else
       return false;
 
}
 
}

I have a server that when restarted emails from the code below every single time. I would like to know what I can use in the code below to regonize the restart and bypass the email send piece in BOLD below.

Any help will be greatly appreciated.

now = currentDateTime()
if (statusInOverride != lastOverrideValue) or (overrideTime != lastOverrideTime)
lastOverrideValue = statusInOverride
lastOverrideTime = overrideTime
if statusInOverride.value == true
overrideStopTime = now
overrideStopTime.minute = now.minute + overrideTime
// Also send an email
overrideHours = overrideTime / 60
mailSend(address, suiteName + " Overridden", suiteName + " has been overridden for " + overrideHours + " hours.");


else
mailSend(address, suiteName + " Override Canceled", suiteName + " has canceled their override. There was " + remainingTime + " remaining.");
remainingTime.duration = 0
endif
endif

if statusInOverride.value == true
remainingTime.duration = delta(now, overrideStopTime)
endif

Hello there,

I am using Dynamic Drive's dhtml windowfile and when I had a link for it to call the popup window, it makes my site deliver a 500 server error. Here is the line of code I'm adding:

Code:

echo '<td><a class="link" href="#" onClick="ajaxwin=dhtmlwindow.open('ajaxbox', 'ajax', 'pages/post.php', 'Composing Mode: Post', 'width=650px,height=400px,left=300px,top=100px,resize=0,scrolling=1'); return false">Compose</a></td>';

It is not a php issue, I plaintext the link and it still did the same thing.

Ok, so I consider myself to be fairly proficient with programming in general, although I am admittedly new to bi-directional networking. So here I am asking about methodological approaches.

A non-disclosure clause prevents me from giving any details, but I don't think they would actually be pertinent. What is important is that the system must accept input from client side Javascript from many users and disseminate that input (once processed) to a number of users. In a way, think multi-channel chat system (totally different environment, but the mechanisms seem similar).

As I see it, I have two options: periodic server polling, or server-sent events (compatibility with IE is not a requisite).

So, my question is, which method (of these two or even something that I am not thinking of) is superior from the standpoint of server bandwidth?

Periodic server polling obviously seems as if it would send a great many unneeded requests, but my hesitation for dismissing this method is that I don't see any client being idle for any considerable length of time (thus the client will send commands to the server quite often) and it simplifies my server software by delegating that section of logic (which data chunks need to be updated) to client CPU's. Additionally, I can throttle the update period based on server load.

Server-sent events initially sounded like a great idea until I thought about the extreme likelihood of a large number of users (upwards of a hundred) interaction with the same chunk of data, thus requiring that each client receive an update every time another client does anything, which is likely once ever second or two, thus resulting in hundreds of updates being sent to hundreds of clients every second. Sounds similar to a denial of service situation to me.

Anyway, I think I already know what I'm going to do for this project, but thought that this might be a good way to introduce myself to these forums.
