I'm writing an ASP.Net MVC intranet application which is accessed via handhelds and a range of browsers. My users all have AD accounts and have different permission to our SQL database views/procs depending on who they area. The database also uses CURRENT_USER for horizontal partitioning.
Because of the range of devices that need to access the application I can't rely on impersonation/delegation or the trusted subsystem. I want the user to simply input username and password (same as AD) when the above mechanisms fail.
Does anyone know how I can use AD username and password in a connection string to access the database without creating a set of SQL mirror accounts? I can't login with network service or a sql proxy account because the database needs to be user aware.
I need a connection string to connect the microsoft 2003 database with my ASP.NET webserviceWhen just making a website I used to use the following connection statement
OleDbConnection dbconn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; data source=" + + Server.MapPath("~/db/SalesCentral.mdb"));
Now as I am using a webservice the Server.MapPath function is giving an error
When I try to encrypt the "connectionStrings" section in the web.config file of my asp.net web application on Windows Server 2008, I'm getting the following error:
Administration utility (2.0.50727) to install and uninstall ASP.NET on the local machine. Copyright (c) Microsoft Corporation. All rights reserved. Note: This utility has limited capabilities on the Windows Vista operating system. It is recommended that you use the "Turn on or off Windows features" option of the "Programs" component of Control Panel to install or remove ASP.NET. It is also recommended that you use the IIS Manager component or the Appcmd.exe tool to configure ASP.NET applications.
The above information is followed by the list of valid options to aspnet_regiis.exe.
The command that I've used is:
aspnet_regiis.exe -pef "connectionStrings" "C:Usersuser1DocumentsMywebsite" -prov "DataProtectionConfigurationProvider"
But, the same command is working fine when used on a Windows Server 2003 machine. The problem is occurring only on Windows Server 2008 with IIS7.
How do you secure a WCF web service when you are using the traditional "connection string in the web.config"?
I have added a WCF service to an application which uses a JQuery post and returns JSON. The request happens on the client side. The purpose of this service is to return search information while the person is typing text into a textbox.
It works well, but there is a problem because the application will be used by a number of people and I am maintaining a role based security within the applications MS SQL database. The connection string to the database is in the web.config file.
In order to run the JQuery call to the web service the user must have at least read access directly to the database. I want to allow the application to control the access, but removing all security to the WCF service opens the application up for external access by unauthorized users.
I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

It works now! I replaces all Run methods in the Student class with DB.Run
But I want to know if it will work fine with a lot of people online, not me only. I'm not sure how static things work with ASP.NET, maybe it'll eat a lot of memory?..
What is the best way to store/access connection strings and most importantly the URLs for different environments (dev, validation, production). I'm using ASP.NET 1.1.

View 1 RepliesI am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
I have an ASP.Net website running on IIS7. The Application Pool is set to ASPv4 Classic.

My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.

When i create a Windows Service for getting information from a Web Application(ASP.NET c#) for scheduling some task in the client machine.
To consume WCF from the web application. I added WCF reference to Window Service project as a service reference, everything seems fine. It updated app.config file, added service reference etc.
it was not working.

I have a SOAP web service and I'm trying to figure how to save/log the last 10 requests for each user. Each user is required to send their user/pass in each request, so it's easy to know who the request originated from. With these last 10 requests saved, my goal is to develop some sort of page that will allow them to log-in with their credentials and view the raw request, the actual SOAP message, http header information, and anything relevant that I can think of.
The point is to allow people to troubleshoot their own connection issues instead of having to contact me each time they can't connect, have trouble formatting their request, etc....
My first thought was to store all this information in memory in a hashtable or something, but that may have scalability issues when we have hundreds/thousands of users hitting the web service.
We could use our database to store these requests. Instead of hitting the database each time, I may need to create some "buffer" mechanism that will only update the database after the buffer gets to a certain number of requests. Is there an existing library or mechanism that will do this?
We can't store these requests on the file system on the machine hosting the web service. Since these requests can potentially contain sensitive information, it's a business decision that I'll need to work around. Or maybe there's a better way to achieve what I'm trying to do?
on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings
'We have to convert the object to a connection string
Dim rootWebConfig As System.Configuration.Configuration
rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec")
Dim connString
As System.Configuration.ConnectionStringSettings
connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1")
Dim strConnString
As
String = connString.ToString().......
I´m trying to use session to store a value (id). The problem is that I have to store it as a string. When trying to use the instance of the id I get the error:

This is where I get the id and that seems to work fine. Session["id"] gets the value.

I have a web application - .net 4. The client is having a requirement that he want to send email to his users on a regular basis about his new courses etc.
The webapplication created will hosted on a "Shared hosting environment" with no excess to windows services - file system other than the web root folder through FTP.
Due to shared hosting i cannot create a windows service for him which will check the database - if there are any scheduled mail to send every 5 min.
So my question is - Is there anyway i can run a wcf web service or any other web based service or page or handler which can keep running and automatically checks the database for any new scheduled mails - if yes start sending it automatically in an different thread.
I am trying to connect linq to dbf file. I am using VS2008 on windows xp with sp2. For most part I can create a connection and see the tables in the server explore, but when I try to drag and drop a table onto the .dbml i get "The selected object is an unsupported data provider". I have been trying to use FoxPro to connect to the DBF. In VS in the Data Connections I go to modify the connection and hit test and the connection says success, but no tables appear.

View 1 RepliesI'm using VS 2010 RTM and SQL Server 2008 on my clean development laptop, running Windows 7 Pro.
Using Visual Studio's Server Explorer, I can easily do an Add Connection by simply right-clicking, and then completing the dialog, and choosing "Use Windows Authentication". I can then click the button "Test Connection".
However, if I wish to do an Add Connection, and then choose "Use SQL Server Authentication", I get a message "Login failed for user 'appSlir'", as shown here:
When I try the same thing on my other development machine, which is VS 2008, SQL Server 2008, and Windows XP Pro, it works fine.
There seems to be a problem/bug that prevents Add Connection with "Use SQL Server Authentication" to SQL Server 2008, when running on Windows 7 Pro.
I have a web service that calls another web service (not my design).The wrapper web service is our code the underlying web service is 3rd party.The issue is that when one of our apps calls the web service wrapper.. it opens a new connection to the underlying web service and that login time is around 10seconds! (3rd party issue)... the calls after the login are fast in testing.SO we are trying to have ONE login for all the calls to the underlying services. However our wrapper service is called one by one..I was thinking if there was a way to store the underlying web service connection in a cache (netbean?) I could reuse it for all web service connections to the 3rd party...
