Connection To .sdf Database From Sub Dir Of Site In Razor?
Apr 4, 2011
I have a small website that I am building using ASP.NET web pages Razor Syntax. It has an SQL CE 4 database in the App_Data folder. The connection and getting records from the database works fine in pages that are in the root directory and the /Account subdirectory. However when trying to get data from the database in pages that are in other subdirectories, connection to the database does not work. I get an error: Connection string "Database.sdf" was not found.It is using the connection string from the Web.config file in the root directory:
When I tried copying the root Web.config to the subdirectory I get the following error:The entry 'Database' has already been added. (C:UsersNameDocumentsVisual Studio 2010WebSitesSmallWebsitesubdirweb.config line 11).At the moment I'm stumped and can't seem to find an answer either in msdn or google.
I am using sqlserver express 2008 (Microsoft Web Platform Installer) and visual studio 10 professionnel.
I am also using last Silverlight4_Tools.exe.
When i enter in Web Site Administration Tool / security I obtain this error
There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may in diagnosing the problem:
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
When I try userprovider
Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

I am working at a site not orginally devleoped by me. The problem is that all the pages are working fine and have no problem at my local site. but the site is not showing any content at live site from database. Niether it shows an error for it. How can I find the problem?
My hosting company states they support .net and razor. However after uploading my website made with webmatrix and razor *.cshtml pages. When i visit my website all i get is 404.17 error messages. As an testcase i decided to add an standard .aspx page. Visiting that page gives the same 404.17 error message :-( .
According to my webhoster my web.config is wrong. However that one is generated by webmatrix. Besides my *.cshtml *.aspx a lot of files and directories are added to the bin folder. What can i check and what should my hosting provider check. When using the check compatibility the asp.net version is shown as unknown? My hosting provider claims my site is running asp.net 4.0 in integrated mode and that should be enough.
I have a question with this tool. I have a database listed in the App_folder, and the database has a connection in Server explorer. The connection string is listed in the web.config file, and I am able to add users and roles with the Web Admin Tool. However,when in the Web Admin Tool, under Configuration tab, I receive an error when I click on the "test" button. The error reads " Could not establish a connection to the database.If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider."
I have set up a small SQL Server database for users to login and also create accounts. There is a problem with the connection string though. Whenever I use the connection string below in the web.config file I get a server error page and cannot view the website. However when I take out this connection string I am able to view the website albeit the database doesn't work.
i have problem in connection strin i host my site and database is in DATA DIRECTORY my site run successfully in offline but an error of connection string in online pls give me an example of string for online i use asp.net, C# and sqlserver 2005
Thing is, if I run this locally and drop my internet connection the web service returns a 500 error (like I want it to do) and deleteCustomer(customer.id); is not called. However, on the live site if I drop my connection the web service does not return an error and deleteCustomer(customer.id); is called even if I don't have a connection to the internet (customer gets deleted from local database without being posted to the web server).
I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
I've started with Flex recently, I've noticed that some plugin for Visual Studio exist, instead of buying a licence for another program (Flex Builder). I was wondering how I could manage to remotely connect to my database with a Flash/Flex application with the help of C#/Asp.Net. If I've correctly understood what I've read in the last few days, there is basically no way to 'query' to a database with Flex 3. So I suppose there is another way by using a webservice in C# on the database server that would respond to the Http query from Flex. Am I right or totally of the track?

I did all the instructions which are in the following link: [URL] in order to do a connection between MySQL database and ASP.NET but I did not successed. Sometimes, it told me that I have a mistake in the <asp: button> and sometimes it told me that I did a mistake in calling (addImage) method. And this is my whole code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HW5._Default" %> <script> public class DataAccess { private string _strConn = @"Driver= {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test1;"; private OdbcConnection _objConn; public DataAccess() { this._objConn = new OdbcConnection(this._strConn); } // This function adds the Images to database public string addImage(timestamp id, byte [] data,string extension) { string strSql = "SELECT * FROM File"; DataSet ds = new DataSet("Image"); OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn); OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP); tempAP.Fill(ds,"Table"); try { this._objConn.Open(); DataRow objNewRow = ds.Tables["Table"].NewRow(); objNewRow["Extension"] = extension; objNewRow["Data"] = buffer; objNewRow["ID"] = id; ds.Tables["Table"].Rows.Add(objNewRow); // trying to update the table to add the image tempAP.Update(ds,"Table"); }.....................................
I have run aspnet_regsql.exe beaucoup times and it creates the database aspnetdb.db. I have created it in my primary database connection and in the SQLExpress connection.
Then I open Visual Studio 2008 and run the ASP.net Web Site Configuration Tool. I click on Provider tab and select Select a single provider for all site management data. The provider shown is AspNetSqlProvider. A book that I'm reading says it should be aspnetdb.
When I click on the test link, I get the following message
Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
In my book, it looks like the aspnetdb database should appear in the app_Data folder of my web site. What is supposed to put it there? Does it get moved from the SQL Server Data folder?
I use the class below in my code-behind to connect to my database. How would I (overload?) this class to choose between multiple connection strings (databases)?
Or should I have a separate class for each connection?
Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
I don't know where to go next as this error message does't give many leads. I have already configured that database with the aspnet_regsql tool. In SQL Mngt. Studio I can see that the database aspnetdb has been created. I'm not sure where to go from here. The only connection string in my web.config file is the one for connecting to my content database.
Currently I'm learning on one of Joe Stagner video "SEC-009-CreateMembershipSchema" I followed exactly as told except for that Joe's is building the database in his JoeStagner server and not JoeStagnerSQLEXPRESS. But in my case I built my database in my MACHINENAMESQLEXPRESS. Another different thing is Joe's using SQL Management 2005 and I'm using the free version of SQL management 2008.
So I followed every step, inch by inch but when I tried to run a test on the AspNetSqlProvider, I'm getting this error Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
here's the connection string I added in just like in Joe's video
