I am trying to write a program where a user logs on to the system and then enters predictions for the world cup matches. I have created the login screen which searches the 'users' database for the inputted username and password - it works (kind of) in the fact that users are granted or denied access. After a successful login, however, the system seems to forget who's logged in, therefore any predictions entered cannot be related the the userID of the 'users' table.
Here's the code I have in the 'login' button of the login screen:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim connection As New SqlClient.SqlConnection
Dim command As New SqlClient.SqlCommand
Dim adaptor As New SqlClient.SqlDataAdapter
[Code] .....
I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.

"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."

I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using
In my application I have a several type of user could be log in. My purpose is to have a restriction with other menu to show on or off. In php I used a session to handle that user id.

I'm currently taking a newbie VB course (online) and in this program that I am writing, I am getting one error (red) that when double clicked in the Error List, takes me to the Application.Designer window and states that "Employee is a type in 'WindowsApplication1' and cannot be used as an expression." The only solution it gives me is to generate the Employee Class (in the designer). When I select that, it gives me 3 more errors (all yellow). The Employee class has been made, so I don't really know where else to go from here.[code]...
