JavaScript class creation query

I have came across 3 different ways of creating a structure or class.

1. Class as a function way

// Class Constructor
function Timer(Source) {

// Class Properties
this.timerID = 0;
this.tStart = null;

// Class Methods
this.UpdateTimer = function() {
};
}

// Example
var timer = new Timer(0);
timer.UpdateTimer();

2. Class.create & prototype way

var WindowDelegate = Class.create();
WindowDelegate.prototype = {
// Class Constructor
initialize: function() {
},
canClose: function(win) {
}
}

3. Declare as a var way

var myObserver = {
variable: null,
anotherVariable: 33
stringVariable: 'asdf',
aFunction: function(a, b) {
}
}

I assume #3 is just a object/structure instance rather than a class definition.

Has anyone came across #1 way? What are the differences between these 3 ways?
And what is the proper way to define a class?

Ummm...#1 and #3 is actually the same (with #3 you create the object directly while #1 specifies the class you can create objects from), and there's a variant of #2 that I use for no other reason than it's neat(er):

ClaimControl = function(controlID) 
{
    BaseClaim.call(this, controlID, 'Claim');	
}

ClaimControl.prototype = new BaseClaim();
ClaimControl.prototype.constructor = ClaimControl;
ClaimControl.superclass = BaseClaim.prototype;

ClaimControl.prototype.Load = function (idClaim)					
{
    return ClaimControl.superclass.Load.call(this, idClaim, 'LoadClaim');			
}

ClaimControl.prototype.Save = function()							
{
    return ClaimControl.superclass.Load.call(this, 'SaveClaim');				
}

Either #1 or #2 or mine above is a proper way to define a class. To define an object you can either use #2 or Javascript Object Notation (JSON)[^]

Does anybody know how to read a file using javascript
I have tried but it seems not to work

fh = fopen("filepath", 0); // Open the file for reading<br />
if(fh!=-1) // If the file has been successfully opened<br />
{<br />
    length = flength(fh);         // Get the length of the file    <br />
    str = fread(fh, length);     // Read in the entire file<br />
    fclose(fh);                    // Close the file<br />
    <br />
// Display the contents of the file    <br />
    write(str);    <br />
}<br />

If you are running this through a web page you probably won't have permissions to open a client's file system.

I have an input element of type file, so i can get the file path on the client side, but i dont know how to read the file on the client's side.

Im using Jboss as my container, and im using JSPs.
Any help.

That doesn't work.

If you run the Javascript in the browser, you can't access any file system.

If you run the Javascript in the server, you can't access the file system of the client, only the server.

Yeah, you'll have to upload to the server and do something with the file there. You can't use JavaScript to read files on a client machine. I think that Flash might be able to do that.. anyone seen this lately?

Javascript and VBScript are ONLY able to access files on your hard drive using Active X controls.

As far as I am aware, javascript is forbidden access to your file system except by using an Active X control. In which case, taken from an older version of JScript :

OpenTextFile Method
=============================
var fs, a, ForAppending;
ForAppending = 8;
fs = new ActiveXObject("Scripting.FileSystemObject");
a = fs.OpenTextFile("c:\\testfile.txt", ForAppending, false);
...
a.Close()

FileExists method
=========================
function ReportFileStatus(filespec)
{
var fso, s = filespec;
fso = new ActiveXObject("Scripting.FileSystemObject");
if (fso.FileExists(filespec))
s += " exists.";
else
s += " doesn't exist.";
return(s);
}

Write method:
=============================
function WriteDemo()
{
var fso, f, r
var ForReading = 1, ForWriting = 2;
fso = new ActiveXObject("Scripting.FileSystemObject")
f = fso.OpenTextFile("c:\\testfile.txt", ForWriting, true)
f.Write("Hello world!");
f.Close();
f = fso.OpenTextFile("c:\\testfile.txt", ForReading);
r = f.ReadLine();
return(r);
}

while other is viewing ? Blush | :O

IIS 6.0 recycling cause web client to hang

sbundgaa10-Jul-06 2:04

We are building a Client/Server application based on ASP.NET.

The server application is an IIS 6.0 hosted XML web service application exposing various web service methods.

The client is a Windows Forms client which are consuming the XML web services.

It's very important the application is available 24 hours a day and therefore we rely on the Worker Process Isolation/recycling feature in IIS 6.0 for maximum availibility.

Unforetunely recycling does not work very well for us - the client hangs if recycling happens during a web service request. After some amount of time we get the WebException "The operation has timed out". On the IIS6.0 machine we see the old worker process has been killed. If a new request is made to the service, a new worker process starts up and the application continues working. So the server side is apparently completely unaware of the hanging client.

To find the root cause I developed the most simple test application which consists of a ASP.Net web service exposing a single web method and a Console application which consumes this Web service in an infinite loop:

Server:

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
[WebMethod]
public void test()
{
int v = 10;
}
}

Client:

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
WebReference.Service s = new ConsoleApplication1.WebReference.Service();
int j = 0;

while (true)
{
s.test();
Console.WriteLine(j.ToString());
j++;
}
}
}
}
If I manually recycle the Application pool running the web service above, the Console application starts hanging until the time out exception occurs. Anybody got an idea why this happens? I thought recycling was supposed to be transparent for the client.

The IIS 6.0 is configured with default settings.

In the HTTPErr log file I get a Timer_AppPool error. I guess this indicates that a request from the console application somehow gets stuck?

Thanks & Regards

You can use the host headers in IIS to do this and have them all point to the same site so you will only need one set of code.

Try searching for "IIS Host Headers" - it's a more complicated and general subject that can easily be answered here. If you have a specific question the forum and I'd be happy to help.

Try reading these first:

http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/596b9108-b1a7-494d-885d-f8941b07554c.mspx?mfr=true

http://www.iisanswers.com/Top10FAQ/t10-hostheaders.htm

Hopefully the above articles will help you out. Assuming that all of the subdomains are pointing at the same IP host headers in IIS will be the way to go.
