I see various examples for this but none working with me? Am i supposed to add some references?
Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
View 1 RepliesI'm at an absolute loss here, I've read so many different things.I just want to add new records to a database I created using SQL Server 2008 with SQL statements in Visual Basic Express 2008. But I can't even connect/get it to recognise the database I created.The database name is 'database.mdf' and is situated in the MSSQL/DATA folder. So far I've read I need to use this code;
Code:
Conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data source=database.mdf"
Conn.Open()

View 9 RepliesWould like to know if it is possible to access a Primavera 6.2.1 database (.mdf) from VB 2008 Express. Would like to take advantage of the existing database, if possible.
It is easy enough to export to Excel and then develop an Access database, but I would like to avoid those steps.
Microsoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.
I'm using VB 2008 Express for our College Project. I'm also running SQL Server 2008 Express and have installed SQL Server Management Studio and used it to create my database. Both software have been installed and running locally. I'm trying to connect to the database from VB 2008 Express. Database connection wizard have 3 options:
connecting to Access db
connecting to SQL Server 3.5 compact db and
connecting to SQL Server db file.

I also notice that the OLE DB connector is not availble as a data connector. Can somebody please confirm that VB 2008 Express can connect directly to SQL Server 2008 Express and how I can achieve it.

View 4 RepliesIt's probably just a case of me not looking in the right place or not seeing the obvious, but does anyone know if a machine with just version 2.0 of the .NET Framework should be able to run a VB.NET Express application which accesses a SQL Server Express database file? Or is there an additional requirement for a non-development machine to have some kind of SQL Server Express runtime component in addition to the 2.0 Framework?It seems to be counterintuitive to expect that a VB.NET application would be able to access any kind of SQL Server data without having some kind of SQL Server host component (Express or otherwise) installed. But then again, it seems just as counterintuitive that Microsoft would require the download and installation of the new framework as well as a separate database runtime in order for the average user to run an application with accesses a local SQL Server Express database.To me, it runs contrary to the whole concept of XCopy deployment to require more than just the application's files and .NET Framework for an application to run properly. But nothing I've read so far explicitly indicates that a user would require anything more than the app files and the framework to run an application which accesses SQL Server Express data. But...I can't get any VB Express applications which uses a SQL Server Express databases to run on any machine that doesn't have SQL Server Express installed.What am I missing?(Apologies if this isn't the right group to post this in.

In the beta version of Beta2 of Visual Studio Professional, when I choose add new connections, I can select a I can select a " SQL Server (SQL Client)" datasource, which works great with my SQL Server Express DB running on the local machine.
In VB2008 Express, though, I can't select a "SQL Server" in the datasource dropdown. I can only try to connect to a Microsoft SQL Server Database File.
When I actually try to connect using the .mdf file that is being managed by my local SQL Server, I get an connection error -- can't make connection to the server (and the usual message about enabling remote connections".
create an SQL Server (express) database (.mdf).
most of the example in the walkthrough make use of the pre made northwind database(.mdf)
i will use the database that i will make to get connected from my application. the connection would client-server and what i have noticed, that this is possible if your database is an SQL version with extension filename of .mdf.
Or if its possible to create this database just using the Visual Studio 2008 Pro(90-day trial)
