IIS 6.0 recycling cause web client to hang - Web Development Discussion Boards

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 ? Blush | :O

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

Hello, does anybody know how to open an "open file dialog box" in javascript?

You use a tag like this: ...

Basically its Site Creator Project on which i' working.

My CLient hav uploaded the 20 subdoamin for me.

but i don't how to use these subdoamin either i have to upload my whole project on these 20 subdoamins. or is there any way which i can set the path to my mail domain directly.

i hope i'm able to let u understand my problem.if any thing unclear plz let me know.

thanx

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.

Dirk Watkins

hi thanx for replying but didn't get ur answer properly it would be better to me if u write the answer little descriptive..(plz explain more)
thanx

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.

Sorry, that first link is for SSL (which you may be able to use later). Here's a better one:

You have to load the object from an external javascript file. I had to do this myself for a project here at work. See code here:

Is it for security reasons?

Microsoft lost a lawsuit regarding the embedding of content. This was its initial attempt at a work around. Rumor has it that will change in IE7 (surprise...surprise)

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?

Regards

Jesus is Love! Tell to someone! Smile | :)

I may be wrong here, but do you need this asterisk at all. If you have two columns of fixed width and a set width on the table, then surely the middle column will expand to the table width anyway...

That depends on the content of the table cells, and in what browser the page is shown.

The size that you specify for a cell is the minimum size, if the browser feels that the cell should be bigger, it will be.

Normally the size of the cells are determined by the size of their content. There is nothing specific in the html standard on how the browser should calculate the sizes, so different browsers will come to different conclusions on how large the cells should be.
