Create A SQL Server (express) Database (.mdf)
Dec 7, 2009
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)

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.

It'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".

I'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()

I have an app developed with VB .NET as front end and SQL Server Express 2005 Database. Now I want to install it on a server so that other client PCs can access it. My gquestions are:
1. Do I have to install SQL Server Express on the Server before I can install my database on it?
2. Do I have to install Visual studio on the clients before I can install the front end?
3. Is there any online walk-through/tutorial on how to accomplish this (ie, installing a database app on a server and connecting the clients)?

I have recently developed a back end database in SQL server 2008 R2 and attached it to a application in VB express 2010.Everything works fine and when i publish the application, it works fine on my machine, but once i try to setup up the application on another machine i get the error message: A network related or instance specific error occurred while establishing a connection to SQL Server. Server was not found or not accessible please verify the instance name is correct or allow remote connections.I have read numerous forums on this saying about changing the connection string and instance name.but with being novice i dont understand what needs to be changed etc.The sql server allows remote connections, but i am unsure what else needs changing to allow the application to work with the database on another machine.

I'm trying to connect from VB 2008 Express Edition to a database in an instance of SQL Server 2008. Both, VB and SQL Server are running on the same machine. From a VB project, when I try to define a new Data Connection I find just three Data sources available: [Code] I selected the last one but when I browse for the mdf file I cannot select it because it tells me that the file is in USE. I have stopped all the services but still I'm not able to link the database file.
Two questions: 1. Is there a way to connect to the SQL Server Instance and from there to select the desired database? 2. How to connect using the Database file.

I use AES encryption in my vb.net 2008 windows forms apps to ....
1. Store user passwords in sql server express database in encrypted form
2. decrypt the encrypted Sql server express connection string password on the fly when connecting to SQl Server over a vpn or direct to web based sql server database
3. decrypt the encrypted ftp site password on the fly when my application connects to my ftp site to upload client's database backups
The issue I have is that the secret key for the encryption / decryption is hard coded within the encryption/decryption functions. So anybody who decompiled my application would be able to generate the same encryption, as they would have the encryption secret key How can you hide the encryption secret key so that if anybody decompiled my app they could not reproduce the decryption function

The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well

I am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

Using Visual Studio .NET 2008 or 2005, is there a way to automatically generate properties for each column in an SQL Server database table? I am assuming other code-generation software exists that will do this. I know with Visio I can connect to my database and it will generate diagrams by table, this would be similar to that.

I have Visual Basic 2010 Express and SQL Server 2008 R2 (not Express) installed on my Windows 7 machine. In Visual Studio, I am attempting to create a Data Connection to a database in SQL server. Server Mgmt Studio is not running. When I attempt to add a connection in Database Explorer, to the AdventureWorks _Data database, I get the message "This file is in use. Enter an new name or close the file that's open in another program." There are no programs running except VB, except maybe for the SQL Server engine running the background.Please note that I can open and access tables within a database in code
within Visual Studio, I just can't add a connection in Database Explorer.Am I doing something wrong? I've been very frustrated on this issue for a long time
