Sharing Website(asp.net) Mdf Database On A Network In Multiuser Environment
Sep 19, 2007
simple question:
I have create a web site in visual studio with form user authentication. Thats create a mdf database in this path:
c:inetpubwwwrootwebsiteapp_dataaspnetdb.mdf
thats use Sql server
i would like to access this database with c# form application on a network with multi-user.
if i change the drive letter of the path above to f: (mapped drive) or \serverc, i got this message
System.Data.SqlClient.SqlException: The file "h:InetpubwwwrootwebsiteApp_DataASPNETDB.MDF" is on a network path that is not supported for database files.
An attempt to attach an auto-named database for file h:InetpubwwwrootwebsiteApp_DataASPNETDB.MDF failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
i read that sql server did not support database sharing with mapped drive or unc share.
So how can i share website database with c# application???
Note: of course if i develop the website and the application on the same machine its work. I want this application run on several work station accessing all the same mdf database with his web user member.

I am in the process of designing a web application for our application that will be available to the general public.Basically will be used to collect information for a case report. I need to know if there is a way from our internal database driven application to push certain data up to the website that the database may be behind a firewall so I cannot make a direct connection to the external database. I thought I heard about some sort of data sharing protocol. I then will be storing the users entered data in the website database and pulling it from the internal application. So basically I need a secure way of sending and receiving data between a server/client app on a LAN system to the Web site database that could be hosted outside the LAN.
I hope this made sense.

Hello,
We are using SQL Server Express 2005 for our application.
I have to lock the data in multi user access.
If user1 access the particular row in employee table, it should lock for the User1.
If user2 tries to access it should prompt the message that the User1 has accessing the particular row. User2 should be able to data in the read only mode. Untill user1 close that row, it should not allow the user2 to make any changes.
Help me how I can achieve this.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
-This is the error that is being generated once the site is hosted. If I run my code from my machine and access my remote sql 2005 database it works fine. It is when I try to login from my URL directly that I get the error. Any thoughts?
Thanks.

We have a valid full backup of a database. We know it is valid, we have restored it twice from the network with no problems, but we do not have access to the network location from our sandbox environment.
The .bak file is sizable at about 9GB. The .bak file resides on our internal network, in a SAN drive. No problems there. When we copy the file from there into a sandbox environment to attempt the restore in the sandbox environment it gets corrupted. We've tried three different times and all three different times it gets corrupted. First time we copied the file over to the sandbox the restore went up to 50% and failed. The second time we copied the file again and attempted the restore again it failed at 70%.
The third time it failed at 60%. The error message we get during the restore is "...Read on ... failed: 13(The data is invalid) Msg 3013, Level 16, State 1, Line 1 Restore database is terminating abnormally."
Now some background here. To move the file our network team is doing this: they have this .vmdk file that they mount out in our production environment (which has access to the network location where the .bak file is), copy the file into the drive, then move the .vmdk file into the sandbox environment(which does not have access to the network location), mount the drive in the sandbox environment, and then I have access to the .bak file from within the sandbox environment.
Something in the process of using the .vmdk file to move the .bak file from production into the sandbox is causing the file to get corrupted.

I am writing a DB-driven application, using Visual Studio. I have a database that i want to be able to move from one computer to another, and still be able to access it. It's probably something simple, but I must be missing out something.
The problem is that if i choose windows authentication, then the DB cannot be used on another computer. I also had no luck when using SQL Authentication.
How can this be done? What form of authentication should be used and how, so that I can just copy my DB from one computer to another, then log into the DB using a username and password?
*Any* help would be greatly appreciated!

Hi;
I have an ASP.NET application with a SQL Express database.Here is the connection string used on the web application:"Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|admindata.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"
Now, i create a Windows application which will run on the server to perform some scheduled tasks, for the Windows application I used this connection string:"Data Source=.SQLEXPRESS;AttachDbFilename=D:WebSitesmywebsite.comwwwApp_Dataadmindata.mdf;Integrated Security=True;User Instance=True"The problem is, when the web site is running and using the database, the windows application can't connect to the database and i don't know where i'm doing wrong, if it's the web application connection string or, if it's the windows application connection string.
I hope someone had the same experience and can point me to a direction.
Thank you;Emerson Brito

Hi !
I almost finish my website and ready to upload it to internet. However, I have a thought of how the database will work.
Here's the scenario. My website is a data-driven dynamic website with SQL as the database manager. I have 3 database files.
After I finish with everything, I will have to deploy the application
to the webserver right? Now, let say I deploy / upload it to a hosting
company. Then, people start using my website, all traffic coming in,
and database are getting larger and larger. Then, let say I decide to
make some changes to my website. I change the website here and there.
However, I haven't uploaded / deployed it to the hosting server yet. I
just make the changes in my computer. I test the application and
changes that I make, everything works fine.
My question is: If I deploy / upload my website to the SAME hosting
company after I make some changes, what will happen to the database in
the hosting server? My website has been used my many users and database
is getting larger. If I deploy ./ upload the website that I have made
changes, will it overwrite the database in the hosting server? Or how
does this work?
Anybody has any idea or maybe has already done it?
Any articles or thoughts will be appreciated!!!
thanks you sooo much in advanced!!!

My database contains over 50 tables of information - some tables are quite large. Rather than upload the entire database (which I imagine could potentially lock out many users from browsing the website), I would like to upload changes to individual tables. My local database contains the most recent table information. What would be the best way to upload individual tables that would only lock one row at a time while the updates were taking place? A DTS package?
Thanks.

Hello everybody,
I intend to used SQL Express database in my website so that I don't have to go through all the database deployment effort when deplying my website.
In this regard, can anyone please tell me what features would it require in my hosting package so that my application works fine (in database context). Would I have to purchase any additional features (like the way we purchase SQL Server database(s) in hosting package) for SQL EXpress in order to deploy my application??

I don't know whether this question belong here, but....
In the past I had many customers using the same website each with their own domain name and their own database. To accomplish that, I used MS Access and placed each customers database in separate directories. I steered the customer to the correct directory using their domain name. I am now trying to accomplish the same thing using aspnetdb.mdf and other .mdf database files. I am using the aspnetdb.mdf database for membership, etc. I want the aspnetdb.mdf database file to be unique for each customer. Does anyone know how to accomplish what I was doing with MS Access using aspnetdb.mdf? Is there any way to have multiple web.config files each of which would be dedicated to a particular customer?

I would wish to know whether it is possible for me to program the code from html or aspx ( from web hosting server ) to our office intranet database which is window server 2005?
I had tried to google for more info but there are too complicated thing for me to understand.
Actually i am doing the web form feedback form from the website for the public to fill in and submit. i am using the mysql from web server to store the records from the feedback form.
We have another database in our server, ms server 2005 to store records in the intranet office only. i need to get the records from mysql to intranet database. i don`t think there is a automated scripting which allow u to auto update the intranet database from mysql( web server )
So i thought of one thing . program html or aspx to insert records directly to our database intranet . but how ?
