Connection String To Pubs Database On SQLExpress Set Up Using Windows Authentication?
May 8, 2010
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
[code]...
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 wrote a program that connect to sql server via a specify server name , user nameasswordim baby as new sqlconnection("server=baby;uid=sa;pwd=sa;database=baby")
I have several programs I have written for my music studio/production company. Many dealing with inventory, customer DB etc. All of my programs are in VB6 and I have started to convert them all to VB.NET. I am getting proficient with VB.NET and connecting to DB using the very simple and generic connection strings, Example:
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.
I've got an app on server 1 that's attempting to copy files from server 2. Server 1 is 'quarantined' from the rest of the local network for security reasons, but the network guy has made a couple of server 1 directories available to server 1 via IP. Thus, in my VB.NET app on server 1 I am trying to do this:
Code:dim filearr as string()filearr = System.IO.Directory.GetFiles("\10.0.0.21packinglists", "*.pdf")
However, I want my app to run unattended and 10.0.0.21 requires a login and password. Can I configure a connection string or something to provide hands-off authentication?
I'm currently designing a client application that connects to a SQL Server 2005 database. My app is being used to display data, allows users to run reports and stats on the data. It is being developed using VB2008. Within my VB2008 project, the connection string to the DB is made via SQLEXPRESS.
The road block that I'm running into right now is that it only allows me to connect to a local DB file (.mdf) only. I tried to connect to a different DB file on a server within the same network domain, and it generated the following error:
"The file "U:Data.mdf" is on a network path that is not supported for database files. An attempt to attach an auto-named database for file U:Data.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share." (where U: is a mapped network drive).
The intention is to have the DB reside on a server, where there is another application that runs as a service to collect the data and then populates this DB. Then my app would just connect to the database, and allows users to run reports based on the data in the DB.
I heard that this is the limitation of SQLEXPRESS: it will not allow connection to a remote database. This is true? If so, is there anyway that I can get around this limitation?
The main reason that I chose SQLEXPRESS in the first place is that because of the licensing issue. The company that I work for do not want to make the users of our software app have to purchase additional license for the full-blown SQL Server Enterprise edition. I also heard that SQL Server Enterprise edition does allow you to connect to a remote DB (.mdf) file.
I use ODBC connection for my application (controlpanel -> administrativetools -> odbc -> DSN) to sql server 2008, and windows authentication it works perfect on windows xp,but now I run it on windows7 and sql server 2008 with sql server authentication.when I make the DSN and query the connection its ok and I got this message (TESTS COMPLETED SUCCESSFULLY!)but when I run the application I got this error (ERROR [28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user ''. ERROR [28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user ''.) I think a little more and I found that Maybe my password doesn't save for my user, when I make that DSN?
I have tested my code in a windows form project and it works great. so now I want it to run as a service.The problem i have is referring to "name" in my configuration string which is in app.config.
Dim settings As ConnectionStringSettings = _ ConfigurationManager.ConnectionStrings(Name)
(Name) is under-squiggled and message name is not declared, file IO functionality is available in the microsoft.visualbasic namespace.
How do I assign a My.Settings.Item connection string to cmd.Connection connection string value?
Dim cmd As New SqlCommand() cmd.Connection = My.Settings.Item("csStaffHoursWorked") cmd.CommandType = CommandType.StoredProcedure cmd.CommandText = "spSaveDeltekImport"
I am creating a windows application which required Dynamic Connection String in the app starting (user need to provide db credentials through a form), After entering the connection credentials user redirected to new win form Everything is working fine but how can I pass my dynamic connection to another form.I tried to save it to App variable but I couldn't (I think its read only) Also I tried save it to registry but can't retrieve values.Is there any other option available ? like writing & retrieving ConString to a text file or XML.
I have written a simple VB.NET program that connects to a MS Access Database. This program runs in Windows 7 XP Mode, but does not run properly in straight Windows 7. Somehow, the Windows 7 does not connect properly or read the MS Access database data properly with the DataAdapter.Fill method. I have dual monitors, so I can run the identical program side by side (one in Windows 7 and the other in XP Mode) - one works and the other doesn't (it doesn't crash, it just get "nothing" from the database when accessing - acts like it's not connected). Has anyone else run into this, or similar, problem with VB.NET and MS Access connectivity?
My Ms-Access .mdb file is on my website. It is in the App_Data Folder
The current connection string is:
OleDbDataAdapter Da = new OleDbDataAdapter("Select * from SerialNo", new OleDbConnection(@"provider=microsoft.jet.oledb.4.0; data source=ftp://ftp.WebsiteName.com/App_Data/SerialNo.mdb"));
Where am I making a mistake in above connection string?
Note: CRs added in the code for better readability
Is it possible change the connection string to a different database when the user changes the database they are using .i have a working program atm but i want to be able to change the connection with out having to change the code. the databases contain information from different years but all have the same tables queries etc.
My query is not the straightforward connection to MS Access.I am using a third application that places all data in an Access database BUT recently they changed the database so that it doesn't end in '.mdb', instead in another suffix: '.accdb'.The database is still an Access database but I cannot connect to it using the connection strings:[code]Previously I was able to use the second connection when the database name ended in '.mdb' (Database Name.mdb).
I have an application that will be called by a database(this application is called from an access shell that uses SQL Server Tables), my question is do I need to provide a connection string to write to the database or since it is already open I can just pass the insert statement. If I am to provide a connection string do I use OLEDB JET 4.0 or ?
I have just written an application for myself and a few other users to use .rdp to connect to a number of servers, by clicking on the appropriate button. In the full version of the program I have two sets of connections one for when we are inside our vpn, which uses local ip addresses and DNS names; and the other which uses the external IP addresses and DNS names.This works quite well; if the user has stored credentials on their pc for the connection they connect straightaway; and if they don't the .rdp dialogue opens up with the server name/address filled in, ready for them to edit the rest of the required information.The problem for me is that this means I have to code 43 different Private Subs and then link the buttons; and I was hoping that instead of individually coding each connection, I could get the users to:Select by an option button whether the connection was internal or external
how to find connection string of any database or any server like, access or sql or Oracle?ans:-to find connection string.first open the new notepad.don't write anything it it.just save any side like my document,or Desktop with any name and give it's extension. " UDL ".after there will be one PC type folder will be created. double click on that folder and go to first tab that is Provider.select your provider like Access, Sql etc. and go to Next tab that is connection. if access then it will tell you enter database name or you can locate your database .mdb file and if it is sql then it will ask you your server name, authentication and database name. select it and click on text connection it will give message connection is OK.then close the file and further open that file with notepad you will get your connection string.
How to use Connection string with VS 2010 during form design? Actually i added database through Data -> Add new Data Sources.And When i publish the project How to publish database too? [code]
I have a VB.Net project that I am running from a local server and I need to use the credentials the user is currently logged in with to upload a file to a folder I create on a SharePoint site on the same domain. I can get it to upload if I specify the credentials but it will not work with system.net.credentialcache.defaultcredentials. It just gives me 3 empty strings and I get a 401 unauthorized error. I have seen a few threads that say you cannot use it with Windows Forms Applications. Is this true? Here is my code:
I just want to know what is your suggestion about storing database connection strings in .NET? I am using My.Setting usually, but now I am facing with versioning of my application. When I upgrade my application to higher version the value in My.Setting has been changed, it didn't remain as user has set before, but changed base on my machine's setting. eg. the value in My.Settings Version 1.0.0.0 (User's computer) is 'ABC' When I develop again some new feature on my machine and set its version to 1.0.0.2, of course the connection string in my computer's My.Setting file is different with User's computer's My.Setting. So when I copied my recent updated file to use's computer, then run the application, the application read the new My.Setting file from my computer but not from their computer. the value in My.Settings Version 1.0.0.2 (Developer's computer) is 'DEF' Therefore I have to reset and reset their connection strings onve I updated their application, that's too annoying?
Dim con As New OleDb.OleDbConnection Try con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = D:\project\login.mdb" con.Open() str = "insert into table1 values(" & Text1.text & ",'" & Text2.text & "')" cmd = New OleDbCommand(str, con) cmd.ExecuteNonQuery() [Code] .....
If I insert integer value it will be updated in database every thing is ok but when I want to write some string in my textboxes and want to send them I get connection error.
if i change it under settings it is working but i want to be able to change it in my running application, or when the application is opened for the first time i should be able to put in die path for the database.
I will be developing a program using visual studio 2008 with ms access 2007 as my database. What I only use is this type of connection string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:mydatabase.mdb;Jet OLEDB:System Database=system.mdw;" but i was asked if it is possible to put the database in sharepoint and I haven't even tried it before. The case is like this, the program that i will do would be installed on some computer units of different branches of the company then the database should be accessible through sharepoint so that every users can access the most updated database.
