Im taking over a project that pulls information from a database.Currently I have everything I need except the username.The person who setup the project did it as a web project so he used the MemberShip class to create unique user keys based on the person's username.
The username is not stored anywhere in the database only these userID keys.
The client wants a desktop app that mimics the website behavior of writing to the database.
Problem:I ask the user to enter in a username at the login. The username connects to the database on the server.I have no way of grabbing any user info after this point as the primary key(USERID) is a unique key and not a username. Is there a way to convert a MemberShip ProviderUserkey into a string Username or am I screwed?

I have a ListView setup in details mode that looks like this: When the user presses the delete button, I need to go ahead and delete their record from the database. This I can do fine, but I'm stuck on how I retrieve the data that is highlighted in the ListView control. I've tried using Google but all the examples I found have failed to work.

I am trying to connect a VB.NET 2003 Oledbdataadapter through the wizard to a SQL Server 2005 Database, but i get an error message during the wizard.These are my steps:New Connection, Select provider (Microsoft OLE DB Provider for SQL Server), Select Connection:server name, log on: use windows NT integrated security, select database. I do all these steps then click "test connection" and it is fine, but when I click "ok" and error message pops up."Unable to connect to database. It is only possible to connect to SQL Server Desktop Engine databases and Microsoft Access Databases with this version of visual studio."

I would like to enable my app to run from a central database, but I dont want to recompile should the DB server change. Are my only two options saving the connection string to an XML file or the registry?
If so I think the XML file will probably be the way I go at least for me. I dont really want to mess with the registry. I just wanted to check what my options are.

I have a program that reads a database file(.csv or.Txt) then allows user to select data from 6 different comboxes and taext boxes are then populated based on the selection made from combobox
I would like to be able to give the user the option to save their settings so next time the program is open it will connect to the same database as the last connection and also have comboboxes go to the last selection Do I have to create a save setting value for each combobox? and the connection string?
is there a simple way to just save everything? so when the program is open it goes back to the last time it was open.

I'm creating a VB.NET 2010 application which is connected to an Access 2010 database. I've set up a connection using the inbuilt connection wizard. I want to pull data from the tables using ADO.NET objects such as the data adapter to create datasets. The data adapter in ADO needs the connection object. Can I pull this from app.config? Should I junk the inbuilt connection and create a new one with code alone? Help.Scott M Brush

I am looking to make a data connection with a network server(sql server 2005). When I run the data source configuration wizard, it allows me only to pick a local database file. I want to use a connection string like this "Data Source=SQLSERVER;Initial Catalog=mydb;User Id=username;Password=password;" I know I can do that programmatically. But I would like to know whether I can do that using the data source wizard so that I will be able to use Bindingsources and tableadapters.
