SQL Authentication - Connect To The Database In VB?
May 21, 2009
My organisation has re-created some SQL test databases, and only enabled Windows Authentication -no problemThey have then created a local accounts on the server, and given them read or write rights to the database.How can i connect to the database in visual basic. I can't use SQL authentication as there is no account,and i can't use windows authentication as only one account has read rights ont the databse. I have tried an sql connection string
myConnection = New SqlConnection("Server=<servername>;Database=<databasename>;UID=<servername><serveraccount>;PWD=<password>"
and it doesn't work. I'm starting to thing our entire SQL authentication model is wrong!
I need to connect to a sql server as a specific user regardless of who is logged in on the pc where the program is running.
[Code]...
gives me "Login failed for user ACMEinvoicing" which is who I want to log in as. I'd think that the problem is the login except that I can right click SQL Server Management Studio and select Run As/The following user and enter ACMEinvoicing and password and it opens up allows me to connect to report server and shows me connect as ACMEinvoicing and allows me to run everything I need to. From within code how do I connect to the sql server reportserver as someone other than who is logged in?
I am using Forms Based Authentication I have extended the Forms Authentication Tables creating a custom table called Profile_Contact that holds the user's GUID, username, email address, and other information. I have another table called Profile_Account which holds company account information such as Company Name, address info, phone numbers etc. This table has a Key Field called IDProfileAccount.
The Intranet was done with forms authentication and stored in a SQL database. how I go about (if possible) authenticating a login in a vb.net project that queries the user settings from the ASP.Net database that was created on the SQL server for the forms Authentication.
I am trying to create a login authentication using the values from SQL database but when i try to login i get the follwing message."value cannot be null. Parameter name: dataset". [code]
I want to use windows authentication in my vb.net application rather than validating against Database. Is there any possiblitiies or APIs that allows me to use Windows authentication? I have user id and passoword text boxes. Once user entered the userid and password, it should validate again Windows authentication.
I have a database (using Microsoft SQL Server Management Studio Express) that is currently being used quite heavily in a functioning application. I am porting this application over to Windows Authentication rather than the current basic authentication system (or lack thereof) that exists.The easiest way that I know to set this up involves using the aspnet_reegsql.exe file to set up some tables for me. This obviously creates its basic tables, such as dbo.aspnet_Roles, dbo.aspnet_Users and dbo.aspnet_UsersInRoles.In the current database, there exist tables named dbo.Users, dbo.UserRole, and dbo.UserRoleMapping. Many of the stored procedures that are written currently for this database rely on these tables.
Where is a good VB.NET tutorial where I can have a username box and a password box and it checks in the database if it's there and if it is then another form will show?
I have an application, I want to connect my database in SOL Server Authentication mode(mixed mode), Hence When I connecting my database through connection string. then what parameter to be passed or what to be checked.
I am trying to follow an example in the VB 2010 book and the author has set up the local server using a named instance of SQLEXPRESS and uses mixed mode authentication with a sa login and wrox as the password the code is then

I am using the Express server initially set up for windows authentication (pubs is one of 6 databases on it) but no matter what I seem to try I can not connect
I'm working on a tool that allows the user to connect to his SQL database and edit some of the database values.First here's a screenshot of the GUI (you can see my problem as well):
I am using VB code behind in Visual Studio 2008 to process data but can't figure out SQLConnection problems. I copied and pasted the connectionstring for my database from the explorer properties window but when I paste it inside the parenthesis of SqlConnection() it gives me an error. Also if I name a variable " dim myconnect As New SqlConnection" in does not give me all of the methods or attributes that are associated with it. Is this a Express Edition limitation or do I need to make some specific declarations to get it to work. this is what I have so far
Dim connectString As String Dim myconnect As New SqlConnection()
[code]....
myconnect. If I try to put open() at the end of this it says its not a member of SqlConnection. I have a dataset but no way to insert into the database
I am trying to connect to a database in VB 2008 express the book I am using is for an older model of VB. The book says to go to view and click on server explorer, and then a database wizard should open. VB 2008 express doesn't have a server explorer under the view section. I know what code I need to enter into to the two buttons I have I just do not know how to open the wizard.
i started on an apllication that reads from a access data base and displays them on the accordinf textboxes.i have always used text files to save and retrive data but i heared somthing about sql and that its much easier, i have looked through the net and read through many forums and thread but i can not find and example of hwo to use sql
I'm a little new to Visual Studio, and want to learn how to connect VB 2008 or VB 2010 to a SQL database. Are there any books or online lessons that teach how to connect Visual Studio to a database?
I have a database setup on my localhost hosting [C:xampp] and I want the mysql server from that to connect to the my one on Visual Basic 08, wait no - the other way round. I want Visual Basic 08 to connect to my database which is hosted locally via my computer.
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed...
someone gave me a link to changing the database connection using an instance. When I tried to type what the instance of my SQL server 2008 I must have put the wrong information into the database connection instance.
What is the database connection instance called for SQL server 2008?
