Access :: Access Database Connection?
Jul 2, 2010I'm having a terrible time being able to connect my access database to my website. I'm using 1and1.com as my host. The database resides in my App_Data folder. I checked everything I could think of on the host side. I cannot query from the database through VWD Express nor create a typed dataset .xsd that will allow quering the database.p.s. - I don't need any sophisticated security on the database, just a homegrown sign in I put together that works fine for my site which is mostly xml file data.

Jul 5, 2010I've got an ASP.NET web project which connect to an SQL Server 2005 DataBase.I think that I'm doing the part of the database connection awfull because everytime I need to do a query (select for example) I'm creating a new connection, opening the connection, creating the command, executing the query, using the results and closing the connection.
Is the rigth way to open a connection in the start of the application and closing at the end?? How can I do that?? I'm retrieving data but what will happen to database server when the application will be used by many people?

Create Methods To Do Stuff Like Opening The Connection To The Database?
Jun 22, 2010I want to be able to create methods to do stuff like opening the connection to the database.Right now if I want to do that I have to put all the code to open the connection with the database in every class.What I did is create a new class called methods, this class is in the App_code folder.I have researched but don't understand how methods are created and how to call them. If someone can give me an example regarding a database connection method, I might be able to really understand how a method works. Basically, this is the code I have to use everytime I want to open a connection to the database:
string connectionString = ConfigurationManager.ConnectionStrings["dbConn"].ConnectionString;
Configuration :: Database On Go Daddy And VS2008 App Can Not Access It Via Web.config Connection String?
Mar 28, 2010I have a database on Go Daddy and my VS2008 app can not access it via web.config connection string. Of course runs great locally in development. I copy/pasted the connection string information from Go Daddy exactly into my web.config file. Web site runs fine on the web but when I try to Login at my login page, i get :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.
I used VS2008 to create the .sql script files and uploaded them to Go Daddy and the Go Daddy people say everything works as they and I can both Login to the database from within GoDaddy.The database i am trying to access consists of the a ASPNETDB.mdf and another Database.mdf together as one in the Go Daddy database.

Access :: Create A Simple Web Form To Query Database?
Jun 8, 2010I'm new here and really, new to asp.net except the very basic things.
I am trying to create a very simple (I think simple) web form with five textboxes and three dropdown boxes and one submit button. The user enters information in the textbox fields and selects from the dropdown lists (which are populated from the database), hits enter and the database runs the query and returns information on a separate page (or can it return to the same page via panels?) The original page returned to a separate page using server transfer.
I have this page already existing in asp but feel that it would be much better served in asp.net.
Can someone point me to a post where I would guess this has been answered many times?
How do I submit the new data to the database, update the records and return the query?
