ut when i make a setup file from my web site and install it the arabic letter not working!!!.

What do you mean by that ? do you mean that you can't type in arabic ? or the data is not being saved correctly ? or the serach facility doesn't work when use arabic characters?

no i can type arabic, but all my labels its not view the arabic letter 

Maybe it has something to do with the font (arabic font is not installed or the server doesn't have arabic language installed) or with the encoding (make sure that all pages are Unicode [Utf8 with signature])

arabic font is  installed and the server arabic language installed, and i use the utf8 unicode, and i have a old setup file from my project and it's working good, also when running the project in vs.net 2005 its working!!!

Please check the database collation, it must be set to arabic.

Well, If you are using varchar or char and not using NCahr or NVarchar, the already exits data may become like that when you change the collation.

Can you try to insert a new records and see if they will be stored correctly ? what is the type of string columns (NChar ? nVarchar?varchar?... ?).

I will move your thread to Sql server forum to get a better help.

the data stores correctly, but the letter in lable not!!! 

Can you post the structure of your table? Do you use nvarchar type for your fields?

OK , so it's not a database issue.

Did you changed the Request/request encoding through the Globaliation section in web.config ?

The default request and response encoding is UTF8 which must handle the arabic characters.

Please if you have the Globalization section in web.config, make sure that the request and response encoding is set to UTF8 which is the default.

<globalization requestEncoding="utf-8"  responseEncoding="utf-8" />

Also, are you facing that issue when you deply the application ? is it working on your dev pc ? because i remeber that i faced that issue when i deployed my website on server that doesn't had the arabic langauge installed on it.

When i  use "publish web site" and deploy it, its working, but when make setup file its not. i use  Microsoft Web Deployment Tool.

now i determine the poblem happen whn i make the deployment file using Microsoft Web Deployment Tool
