Architecture :: How To Change The TableAdapters To Get The Connection String From The App/web.config File

Nov 9, 2010

I will explain the my current yet simple architecture of my application(s). At the moment I have my main web application as a separate project. I then reference the CoreBLLDAL (Business Logic and Data Access) Project so that several projects can have access to the BLL/DAL Project.

Within the CoreBLLDLL Project I use TableAdapters for my DAL.

I have just upgraded to VS2010 and I would like to make use of the Config Transforms, allowing me to have a separate web.config for test and production - however, TableAdapter get the connection string from the Settings.settings file.

How can I change the TableAdapters to get the connection string from the app/web.config file? I read that you can change this within the designer file for the TableAdapters by using ConfigurationManager, however, I tried this but I do not have access to the ConfigurationManager namespace. I presume this is because the project is a class library and not a web application - I am not too sure.

Security :: The SSE Provider Did Not Find The Database File Specified In The Connection String

Feb 11, 2011

I have a very basic web site that uses a standard login control. It was original built using ASP.NET 2.0, and when I preformed a few site improvments, VS 2010 upgraded the site to version 4.0. Locally, everything is fine. But live, everything is working except the login authentication. All other pages that use the database work fine.

does the upgrade process affect the database? As this is the only thing I've not replaced on the live server.

The error I get with the login is:

The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file Any thoughts?

I want to take a value from the web.config -> app settings via asp tag.

The reason is that inside the selectcommand inside the sqldatasource I use four-part-name and the IP is hard coded in some aspx files.

I want it to be taken from appsettings property instead.

Web Forms :: Display A Record Count From Sql Database Connection?

Oct 29, 2010

sometimes learning asp.net feels so heavy handed compared to some of the general purpose scripting languages like php. for examples, all i want to do is create a sql connection that pulls a row count and displays that number. I don't need a grid, list, detail page, etc., nothing this heavy... a simply query that will display a simple bit of text. for the life of me I can't figure out how to do it. Using these controls, I'm not in the code behind with the query, so I wouldn't attach this to a label (or would i), and there's nothing i see in the toolbox that does what i want. Perhaps i'm too accustomed to php but it feels like with asp.net, major things are simple, and simple things are hard.
