ASPNETDB.mdf ...already In Use... Error And Broader Questions
Jul 26, 2007
When you create and host an ASP.Net 2.0 site on your local computer and then configure .Net 2.0's drop-in user registration and management system it creates a SQL file named ASPNETDB.mdf with a whole bunch of tables and stored procedures (…as most of you know). If you add your own custom tables to that database file and then try to call those tables you get an error that says that ASPNETDB.mdf is already in use. One way to get around this is to create a separate database in the form of another ".mdf" file and then put all of your own custom tables in it. You avoid the "...already in use..." errors that way but all your user accounts and the primary key structure that identifies them are in the original ASPNETDB.mdf file. This makes it impossible to do primary/foreign key relationships between those tables and those in the new separate database you created. It's kind of a catch-22 situation...unless I'm missing something that relates to releasing the ASPNETDB.mdf file from use whenever it is called so that additional tables and queries against that database file can be made without the "…already in use…" error cropping up. I am wondering if this problem is because the ASPNETDB.mdf file is not a "real" SQL database and as such imposes multiple-connectivity limitations such as those I am seeing. If this is true, migrating to a real SQL database would alleviate this? Finally, from a broader security and scalability standpoint…what are the best practices relating to use of the ASPNETDB.mdf database for all your custom tables? Should an additional database be created for all my application's custom tables (leading to the primary/foreign key problems) or should the additional tables be put into the ASPNETDB.mdf file (with some way of working around the "…already in use…" error)? A long-winded and broad question…thanks in advance for any responses.
I developed an ASP.NET 3.5 site in VWD 2008 Express (with SQL Server 2005 Express) on Vista Home Basic (no IIS). So I then moved my source over to an XP Pro machine with IIS 5.1 and installed .NET 3.5 and SQL Server 2005 Express. Brought up the site, but it failed when I attempted to login. What do I have to do to get this to work? Do I need to attach the ASPNETDB.MDF in my APP_DATA directory to my SQLServerExpress? Was this taken care of by the ASP.NET config tool when I set up users/roles on the Vista machine?Do I need to set some permissions? Like I said this was working only on through the built in webserver in VWD 2008 Express.ThanksEric
I created my own table on the ASPNETDB.mdf file. When i try to insert data on it, i get an exception: System.Data.SqlClient.SqlException was unhandled by user code Message="String or binary data would be truncated.

Exception Details: System.Data.SqlClient.SqlException: 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) If I insert a wrong password I get the same error message. Which means that I don’t have access to the file. I definitely could use some help since from my provider I get none. Thank you Dov Kruman
I am getting the error: Cannot open database "aspnetdb" requested by the login. The login failed. When I browse to my ASP.NET 3.5 LINQ web application on the IIS 6.0 server on Server 2003. I imagine this is because while I granted SQL Server 2005 login and permissions to my database that the application stores its data in, I did NOT grant any rights to the service account the IIS Application Pool uses for its identity to the aspnetdb database on SQL Server which is where all my roles information is stored at. My question is what are the MINIMUM permissions needed for this database so it can perform its roles related functions? I'm using Windows Authentications with the SQL Role provider for authorization.
Thank you.
EDIT: I think I only need to open the aspnetdb database and add my login to the aspnet_Roles_FullAccess role. Is that correct?
Hi everyone, i have already created posts about this problem and im aware theres millions of replys, but i still cant get this to work and its driving me mad. The posts i have seen i dont understand? Im using the standard ASPNETDB Database, i have never opened up SQL Server Management studio, although i do have the express edition. i have tried everything and i am totally stumped as to what to do. Heres my web.config. It works in VWD 2005 Express, but not in WWWROOT or on webserver? PLEASE PLEASE PLEASE Can someone help me!!!!!!!!!

I have installed Sp1 for Sql Server 2005 I also received "locked files" and "reboot required". These errors I can find on all forums and do not worry me anymore. However i still would like to know more about the messages in the log files.
- What does this mean: "Failed to read associated hotfix build information for the following file"...... - What does this men: "Failed to read version information for the following file".........
- Why are some products NOT APPLIED, while in the other log file it says "SUCCES" for the same product? These beneath the 2 log files.
Question 1: SQL TimeOut Error I get this when i run my program and when it happens the program no longer displays data from the database. When i restart the program it seems to work fine. Is there away to fix this or at least make a message to the user telling them to restart the program?
Question 2: Can I e-mail form info to myself? I want the user to be able to fill a form and click submit and have it emailed to myself. how can i go about doing that?

1. Is it legal and OK to use a MSDN SQL copy on a production environment or is it strickly for test environments ??
2. If I own a legal copy of SQL 7 with 5 cals, can I legally use SQL MSDE and have more than 5 people access my SQL server or am I also limited to 5 users as my original ??
Using VS2005, VB backend and javascript, I have developed a relatively simple site - its got a few (12) simple aspx pages but its mostly client side javascript. Keeping disk storage costs down is a big concern with this my site. The disk usage for the site is ~24M. Since this was larger than I expected I started inspecting the files comprising my site and found that the "ASPNETDB.MDF" in my "App_data" folder is consuming 10.2M by itself. The thing is that site only has a few pages with calls to SQL Server - but I never did anything (that I know of) with ASPNETDB.MDF. Through VS2005, I opened up the MDF file and poked around, everything that I looked at was empty (NULL). So my questions are:
What is causing the ASPNETDB.MDF to consume 10.2M even thought I can't see any data stored in it? Is there anyway for my to reduce the size of this file? If so, how? Your input appreciated.
I'm creating a website in VWDexpress 2005 using a database, with string "SqlDataProvider". I have only one small-sized database. When I try to run my application in login mode (not using LoginView, I create it manually), the application cannot log me in, instead there's a weird error said some kind of "cannot use the ], [ or ) in database name". I don't configure the ASP.NET Configuration (which is opened in browser to make roles etc), I create all the controls manually. I don't have any other automatically-generated databases such as ASPNETDB.mdf because it cost lots memory! Oh, I used it before and the weird error I mentioned is occur when I excluded the ASPNETDB.mdf. I'm confused, why would the same error occur since I create everything manually? Any solutions? Thank you.
I am creating a new application and want to store the sql database. But i need the aspnetdb.mdf. I dont know where is the database located or do we have any scripts to create the database. Any help would be useful
In response to a problem I have, my web hosting company asked me to rename aspnetdb.mdf. When I ask why, I was given this response
...it is because SQLexpless is developed for single database. If there is a same db name in the server, it cannot attach to the server. In order to prevent conflict, so that you need to change the SQLexpress's dbname into others to prevent conflict with others db name...
I thought I had this corrected, but in fact don't. According to http://msdn2.microsoft.com/en-us/library/ms228037.aspx SQL Express is supposed to automatically generate a copy of ASPNETDB.mdf in the App_Data folder of the Express edition development suites (I'm using Visual Web Developer 2005).
In my case, it doesn't, and I can't figure out how to trigger it manually. I've read every post I can find, especially http://forums.microsoft.com/msdn/showpost.aspx?postid=98346&siteid=1
However, that mainly applies to deploying a database that already exists. I have already tried deleting the files as suggested and they do reappear in the appropriate folder, but I'm still not getting the ASPNETDB.mdf file in my apps.
Any help on this would be greatly appreciated. I've had a post up on the Visual Web Developer forum, but folk are staying away in droves. Also tried uninstall and reinstall all the way down to IIS 5.1
I been all over this forum trying to find out how to get the aspnetdb.mdf running on my remote site and its driving me nuts. i been using VWD 2005 express Edition and SQL Express Error Server Error in '/' Application. An attempt to attach an auto-named database for file I:DataWebqsh.eumarker_93618920-db3b-4a04-a274-3fb613afc5dfwwwApp_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. over the last week it has been a nightmare trying to get anything working on the site but i have got all the other databases working but i can get the aspnetdb.mdf working. i am very new to ASP.net so please use the he kiss method "Keep It Simple, Stupid!" as im a newbe to this and it will just go over my head. Thanks

All help is greatly appreciated!
When I first sign up with Visual Web Developer, Do I continue to use this database ASPNETDB.MDF or do I need to connect to the Microsoft SQL Server Database? Does Visual Web Developer Express automaticaliyy connect to SQL Server Express Edition? Thanks Computergirl
I created a website using Visual web developer express edition (including SQL Express). No the user management section of the site (the login/logout database) was created automatically and SQL Server express was installed at my computer under the instance name of SQLExpress. I uploaded it to my web host and he hooked up the ASPNETDB for me. Now the problem is that ASPNETDB has an id password and I was given the MSSQL Server IP. How do I configure my website to accommodate that? Any help will be extremely useful!!!
Hi I have a problem most of the hosting companies I have seen offer the hosting package I want offering 1 MS SQL Server database and if you want to then they charge twice the price. The problem is I have heard you can use your own database for the memberships, roles, etc and have other tables for your other stuff. It's just I don't know and can't find the steps to do this.

Hello!I have my own database file, but when I run my site in debug mode it creates aspnetdb.mdf again and stores all users in there ... question is - why? :((I've attached my own db to sql server express, ran "aspnet_regsql.exe -W" on it, so it got all the schema in there.Here's what I have in my web.config-----------<connectionStrings> <add name="SqlServices" connectionString="Data Source=MESQLEXPRESS;Initial Catalog=myOwnDB;Persist Security Info=True;User ID=user;PWD=password" providerName="System.Data.SqlClient"/> </connectionStrings><membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="20"> <providers> <remove name="AspNetSqlProvider" /> <add name="SqlProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="SqlServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" passwordFormat="Hashed" requiresUniqueEmail="true" maxInvalidPasswordAttempts="5" passwordAttemptWindow="10" minRequiredPasswordLength="5" minRequiredNonalphanumericCharacters="0" applicationName="/" /> </providers> </membership>----------so i connect straight to sql server, not local file (so i dont have to attach / detach the db all the time)but when i create new user through ASP Config, it creates them in aspnetdb.mdb file :(can anyone explain me what im doing wrong here?thanks in advance!
Hi: I am using the built in securty database from vs2005 I am trying to write an insert trigger that will add a role each time a user is added but I seem to be having difficulty I believe it's with the uniqueidentifier datatype. when I run this trigger via an insert statement I get the following error. Can anyone set me straight? ========error============== Cannot insert the value NULL into column 'RoleId', table 'R:AAAPROJECTSASPVS2005MERCERBUCKSAPP_DATAASPNETDB.MDF.dbo.aspnet_UsersInRoles'; column does not allow nulls.

i changed the appplication name on a aspnetdb equipped mdf (SQL express) , but have another similar mdf (SQL express) in a different web application, this database has the same applicationID in the "aspnetdb" tables,
these are meant to be two different web applications running under IIS, the root folder name for each web application is also different. also the mdf (SQL express) names are different as well
but still feel like i might be headed for jeporadry, ie does IIS want a unique applicationID for each asnpnetdb equipped mdf, or is the applicationID only applicable to the mdf it is in and the web application the mdf is running under??
Hello, I'm getting up to speed with VS2005 and use SQL Server 2005. I'm using the login control in a test web app. When I run the app I get this error: Cannot open database "aspnetdb" requested by the login. The login failed.Login failed for user 'UserIDASPNET'. The connection string I'm using is: data source=localhost;Integrated Security=SSPI;Initial Catalog=aspnetdb; The AspNetSqlProvider in the web administration tool connects to the database. My question is, Is this a connection string issue, and user ID issue, a rights issue or is it something else? Thanks, Gaikhe
Hi, I am building a web site that requires authentication and offers role-based services. The standard login controls provide ample functionality for authentication and role definition as well as some additional info (e.g. e-mail addresses) that I need. I also need to create my own tables to contain my business data, which in many cases it tied to the logged in user, e.g. I may need to SELECT fields from my own tables WHERE users are in a specific role. Since the login controls use ASPNETDB.MDF I wonder if I should create my application's tables inside that database to make is easier to pull information from existing tables and my own tables. Or shuold I instead create a different database for my logic and then write code to stitch the data together from both databases? Another alternative I can think of is to build my own database that contains my business and authentication tables, then build a custom authentication provider on top of it. Are there any performance caveats/benefits to these approaches? Any help/advice is greatly appreciated. Thanks.
In developing a VWDE project I added 2 columns to the User table in the ASPNETDB.mdf database. I can see the columns in the Data Definition and I can see the values I added when I Show Table Data but I cannot access them with a SQLDataSource control? The SQLDataSource shows all of the columns in that table except the ones I added. Any suggestions? Thanks.
I was thinking of adding tables to ASPNetDB.mdf and have one of those tables have column userid as a foreign key from aspnet_Users When I try to create relationship in Diagram, I get error saying that "data typ properties does not match" userid in aspNet_Users is uniqueidentifier and userid (fk) in new table is int What should I use, should I do that at all?
