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)[^]

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);
}

Hi,
Is there a way for people to share a file like a ms-Word doc
and assign one party permission to view it while another party could edit it
while other is viewing ?

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.

If you have 3 columns in one table, and place in the first TD 100px, in tha last 200px and in the middle TD one asterisk "*", the middle column enlarge to fit the table width.
I can use this asterisk (*) in css? The asterisk is reserved in css, then what we can use?
