PERFORMANCE QUESTION

I want to built a web page which is gonna have multiple languages. Which one
is the best way ? Using a Xml file to store languages and their
corresponding fields or Using a MS-SQL Database ?
What do you recommend me to have best performance about multilanguage
web-sites?if you are worried about performance, the localized content should be stored
in the cache, which means whether you use XML or a database, the performance
will be excellent.

It really depends. For large numbers of records, SQL will far outperform
XML. Parsing XML is a relatively slow thing. If you are going to have 10K
records with information regarding different words in different languages,
XML is going to be slow, and so will XPath.
If you have 200 records, well, maybe it doesn't matter as much.
Also, you can use Access as your database, which is file based, so similar
to an XML file in that regard.
You should look at your situation, and see what works best for you. The key
is to box up all the translation code into some methods, so if you switch
implementations, only those few methods have to change.

File I/O is simple and no network operation needed... But again if you are
delpoying to a server, will it be easy to get deployed and get read access
or read-write for the XMLfile?
personally i will go with DB, if your application is already using a
Database for other purposes.. the reason is updating is easy... or else you
have to find ways to deploy the new XML file to the server... might be
painful sometimes..
if you don't have a DB in the app... do a XML file...

There is a standardized feature in ASP.NET for binding the text properties
of web controls with alternate content, stored in XML based "resource
files", keyed on the language settings of the user's browser.

Savas,
Is this real a question. Whatever system your choose is the only moment that
it can be from importance be as the user changes the language. As most use
the by IE returned standard information in what is the language and than a
Cookie if that changes, what is a one time operation. For the rest it is
equal to getting all kind of information.
Just my thought,
Cor

Performing a download along with another action

I have a webform that contains a button which I want to do three things:

1. Delete a record from a database
2. Let the user download a text file that is generated
3. Refresh the page to show that the record was deleted

I am able to do any of these things separately with no trouble. The problem
occurs when I try to offer a download AND call my refresh method. When I try
to do a download and call my refresh method, only the download is performed,
regardless of whether the refresh is called before or after the download.
Here is snippet of my code that does the download and refresh:

Me.RefreshEvents()
Response.ClearContent()
Response.ContentType = "text/plain"
Response.AddHeader("content-disposition", "attachment;filename=" &
downloadname)
Response.Write(downloadtext)
Response.End()

If I comment out five lines that do the download, Me.RefreshEvents() does
what I want and would expect, but otherwise it appears to do nothing. I
don't care whether Me.RefreshEvents() is called before or after doing the
download, as long as they are both done. What can I do to make sure both of
these tasks get completed?

http://www.nathansokalski.com/when the browser requests a page (like when the user hit the button), the
browser only expects one document back. you can do one of several options

1) refesh page and enable a download button
2) refresh page and use client script to start a download
3) refresh page and use meta tag to start download

in all cases you refresh the page and then download the text file.

This can be done. What is meant by refreshing the page, something like
re-display the grid?
So the user hits the button:
1. You delete the record and re-bind the grid so the user can see the
changes on this page.
2. You save the text to be downloaded in a session variable - this is the
simplest, or on disk, or database record, etc.
3. You have a Protected string variable, say MustDownLoad, and set it's
value "Yes", or anything, to be read by Java script.
4. In the HTML view of the form, right at the bottom, you must add Java
script to open a new window to download the text:
<script language="javascript">
if ("<%=MustDownLoad%>" != "") {
window.open("Form_DownLoadText.aspx");
}
</script>
5. You create a new form Form_DownLoadText.aspx and in it, you read the text
from the session variable/disk/record and do the
Response.ClearContent()
Response.ContentType = "text/plain"

Nathan,

Maybe a stupid question, why do you not use the HTML command File Field. It
is a strange name because AFAIK mostly is used Download Button.

It is the HTML tag <Input type=file

Hi guys,
What is faster to IIS, a Code Behind file or a In Code aspx file?
When we call for a Class like dim f as new MyClass if it's a big class,
will it take longer to run? or the IIS only access the funcions that we call
inside the class when we call it?
Thanks

"a portuguese in Denmark"An ASPX file is parsed at run-time to MSIL, which is then compiled to a
native image. A DLL is MSIL, so it takes fewer operations to compile it to a
native image. Of course, caching mechanisms make most of that moot, as the
resources are no continually being re-compiled.

Hi Kevin,
but I'm not talking about DLL, only VB files (classes) and having the code
in the same page or separete one.
I dont thing that the IIS will take my hole site and put it in diferent
DLL's (there is an option in framework 2.0 that we can do that into one DLL)
but this is not my point.

Perhaps an XML file might do this trick?

I've got an application that many supervisors are going to use. However,
each one needs to see a different part of the information. Some supervisors
will all have the same view of the information with the same fields showing.
Others have variations on those fields to see.

The idea is that when an error is made in a certain business process, a log
entry of it would be made. The department responsible would have its
supervisor notified by e-mail. So, in our database, we have a list of all
the departments, but no easy association from the Department to its
supervisor. (Perhaps that's something I'll need to work on)

Anyways, what I want to do is to store an XML file of the department ID's
and the ID of the supervisor to send an e-mail to. Not only that, but I'd
like to use an XML file to control which fields a person needs to see. But
I'm no XML guru by any means. With only 2.5 days to do this, I'm open to
suggestions on how to best implement these requirements.

--
Stephajn CraigThis is a start...

The information I'm "protecting" and at the same time showing is coming out
of a database. The output is a datagrid bound to a datatable. The thought
occurs to me to pass the datatable through an XML transformation (perhaps
using an XSD file?) for whatever user is currently looking at it. And, to
use another XML file for determining the type of transformation to take
place. This way, no changes would have to be made to the underlying code of
the application, but rather to an XML file.

But while I may have a bit of theoretical design in mind,
1. I don't know if it's correct.
2. I don't have any idea how to implement this theory if I AM right.

Permission denied

Me again :)

I'm trying to delete a file and getting this:

System.UnauthorizedAccessException: Access to the path "C:/inetpub/wwwroot/appdata/photos/" is denied.

I have identity impersonate="false" and the ASPNET account has full rights for the folder.
The app is running on a remote server.

Any ideas? I'm getting frustrated here.

Thanks,

DavidAre you sure the application pool that your app is running on is using the ASPNET user account to run? Make sure its not the IISWPG user (or any other user for that matter). If your remote box is running Windows 2003, I bet that is the issue..
Thanks Sharbel, if IIS_WPG is a problem, what is the correct configuration for the application pool identity? This is an intranet server on an internal network.

David
Well, it's not that it's 'incorrect', it's just that you might be giving the ASPNET user permission, but it's the IIS_WPG that needs it.

We have a webservice that can log information to a text file on the local
machine. The ability to log information is configurable. The .net web service
is called from a vb dll. From the vb side of the fence, we're getting an
error message that indicates access is denied to the log file. The folder and
log file both have the asnet user set up with full control. Additionally the
parent folders have list access and read access for the user. The security
event log contains a record with the permissions being requested.

Additional info: the web service works on two other boxes with simular
configurations. The major difference is the box that doesn't work is in the
DMZ and does not have a domain controller.

Any ideas?

KenHi Ken,

In your webservice, do you allow or deny anonymous access?
if you don't deny anonymous access, you might need to
grant permossion to another account IUSR (Ineternet Guest
Account).

Permission denied creating directory

Hi,
I have a created a simple file upload asp.net web page which also creates di
rectories on the fly using the following code:
string fullpath = Server.MapPath(".\\..\\..\\" + path);
DirectoryInfo dir = new DirectoryInfo(fullpath);
if(!dir.Exists)
dir.Create();
Now the dir.Create() statement gives me a permission denied. The ASP.NET use
r has been giving full control to the directory and in IIS Admin the directo
ry has write permissions for scripts set. There is no problem in uploading t
he file to an already creat
ed directory which I find extremely weird!
What goes wrong ?
My OS is Windows XP using .NET framework 1.1. All the latest security patche
s are installed.Hi,
Does the "System" account have access?

Hi Christoffer:
One way to trouble shoot these types of problems is to enable auditing
and find out "who" is getting the access denied message.
See:
http://www.pluralsight.com/keith/bo...leauditing.html
and
http://www.pluralsight.com/keith/bo...fileaccess.html
Also, make sure the permissions apply to subfolders - click "Advanced"
and check the "Apply To" column.

I have found what the problem was. The ASPNET user I added was from another
domain. Now I have added the local ASPNET user and it works.
The audit thing really helped. Thank you very much!

balaImpersonation only allows access to local resources as the user who's using
your site. You want delegation which will allow off-host access as the user
who has authenticated in the browser. In essence it means you need to enable
this in AD for the machine that's running your webserver. Check out this

Ok, that shouldn't matter with delegation.

For delegation you'll have to be using kerb. The username doesn't matter,
the important thing is to configure the server to be trusted for delegation.

As Brock was indicating, you need to delegate credentials which requires Kerberos if your web
application is configured for Integrated Windows Security.

As Brock was indicating, you need to delegate credentials which requires Ker
beros if your web
application is configured for Integrated Windows Security.

Permission Denied Writing to a file

I'm getting a 'permission denied' error when I try to write to a file. I'm running Windows XP Professions, FAT32, and I've set the aspnet user to be an administrator. And I still get this error. I know it's not that the folder doesn't exist, because if I change the path to one that doesn't exist I get the appropriate error that it doesn't exist.

Help.

buzzWow! I hope this server is not exposed to the Internet in any way.
First, you should use NTFS and not FAT32 (there are no permissions on FAT32 disks).
And making ASPNET an administrator is something you should never do. You could edit the machine.config file instead and make the process use SYSTEM instead of ASPNET. I don't even recommend doing this, and you should really just give enough rights on the directories to ASPNET so that you can write to your file.
Does this help?
I'm just in development on my desktop for now, which is why it's FAT32, and the only reason why I made the ASPNET account an admin was to troubleshoot my permission denied error. That's why I mentioned it, because even with it being an admin I'm still getting this error.
You should use NTFS on your dev machines too. I doubt that you will be able to sort this one out except if you use NTFS. I haven't checked this, but I wouldn't be surprised if we used low permissions by default if the file system is Fat, as there are no permissions on this file system.
And 'low permissions' means no write permission, ever, anywhere? That would be remarkably restrictive, wouldn't it? Aren't there some IIS settings I can look at? I also went into my app in IIS and gave write permission in there and that didn't work either.

Thanks for your input.

Once again, I'm not sure about that at all.
But usually, a web site has no need to write files.
And it would be incredibly dangerous to allow writing to an unprotected file system by default.
I strongly recommend you use NTFS in all circumstances. Fat32 is only there for Win9x compatibility.
I see, well I'll look into converting to NTFS.

>> But usually, a web site has no need to write files.

Is this true? I'm not an expert, but what about uploading files, etc? Also, I want to write to a file for logging purposes, for when my database goes down.

Thanks for all your help!

buzz
Yes, that's why I said "usually".
Most sites don't need to upload files. And if you upload, you should do so in a directory that's not acessible from the web, for obvious security reasons, whenever possible. And you should always require reliable authentication when you allow for it.
Logging can be done using the System.Diagnostics namespace, using the standard Windows event logs.

Permission Failures with an embedded windows form. What’s the proper way to do this?

I have a windows web form control that opens up a serial port. When I try to embed it an HTML file, I get a securityException when it opens the port. --System.Security.SecurityException: Request for permission of type System.Security.Permissions.SecurityPermission, mscorlib,.......

1) Is there any way I can just tell the browser to trust this object, or just completely trust anything and everything from a certain web site?

2) Right now I had the DLL download from the server when the page loads. It is quite small so speed isn't an issue, I like the concept of downloading it everytime it is used because it will be easier to keep updated. But in terms of permission I was wondering if the proper way may be to install it as a plug in or addon?

The syntax I currently use is :

<object id="SIOControl1"classid="http:SIOControl.dll#SIOControl.SIOTestControl" height="500" width="500" VIEWASTEXT>

You cant programatically "tell" the browser to just trust it, nor can you tell the browser to trust everything from a specific site, not from your application. Imagine the huge security hole that would be. What you CAN do is as the "user" of said site:

Through Internet Options > Sites > Trusted Sites:

Add the address of your website to the trusted sites section. Then set the security of that "zone" to match what you need to accomplish what you're after.

I don't think the solution is as simple as adding it to a trusted site. Just for testing purposes I did that, and set all IE secuirty options and it still dosn't work.

I've tried to add FullTrust to the site with caspol, but to tell you the truth, I just can seem to figure out the proper command.

I've tried: caspol -addgroup LocalIntranet -urlhttp://localhost/SIOControl/* FullTrust

but it tells me that I have an Invalid Label or name, but when I do a caspol -lg I see LocalIntranet there?

permission to File.Exists

Hi,
In my Web Application, I need to check whether a file exists. I'm using the
System.IO.File.Exists("filename") method.
This file is in another server.
Always the return's method is False. But through the windows explorer I have
permission to access it. So Can I do?
thanks a lot
Marcos SantosMost likely the default ASPNET user account does not have network security
privileges.
To test this theory, use impersonation to have the web application run under
your user account.

Permission to write a file

Hi all
I'm coding a Web application which requires to write an XML file into a
folder. I'm wondering other than account Everyone which else I can set
permission so that my application can have the rights to write the file.You have to set permissions on the user that asp.net is working on.
By default it is ASPNET
Regards
Martin
