Installing An Application With SQL Server Express Database?
Jun 11, 2010
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)?
how can i deploy windows application developed using Vb.net and Sqlserver R2 Express as local database?..how can i make it in setup format(including sqlserver) to deliver to clients?is it compulsory the client should install SQL Server R2 Express in his system apart from the installation of this windows application?
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.
Is it possible to connect to a database on SQL Server R2 Express from Visual Basic Express? I am following a set of tutorial videos done in SQL Server 2005, but cannot seem to connect to create the database. I have created the database in SQL Server R2 Express, but cannot connect. Is there a work around?
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.
When I try to install the application from the files it produces when I follow the prompts from Build - > Publish (Visual Studio 2010) onto another computer, and then run the application on the other computer, it wont connect to the SQL database on the original computer. I've been receiving a timeout error or one which says it can't find the server.I have no idea where to start looking to fix this, both computers are running XP and 4.0 .NET Framework. The computers are linked on the same network.I think my connection string is the culprit, but I don't know how it should be set up to run on multiple computers. Here's my connection string:[code]The connection string works on the application I've installed on the original computer, but not the second computer I've tried installing the application on.My second thought was that it could be the server which is wrong, I've just used the name of my computer for that, is this correct? I thought it may be because all the computers are connected on the network.

How can I deploy my sql server express 2008 database to client that do not have sql server instance at all? Since the server connection in my vb.net program is hard-coded, I want the server instance on client side has the same instant name as mine.
I am totally confused about the way SQL server Express works with my application, it seems like it is a hit and miss whether it works or not.In my Server Explorer if I show data, I see data in my tables.
3 years ago I developed a vb.net application that connect to sql express 2005 data base.The application worked fine.e replaced our computers, so we installed the application again. (The same exe file, the same sql server and so on).Now, only when loading few forms I receive the following message: n error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)Note that when we log in to the application, a connection is needed. The user verifying is working fine; it means that the connection is working properly.
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 get 'sqlconnection' is ambiguous in the name space 'system.data.sqlclient' What is this confusion? What I am trying is to connect a .mdf (sql server express) database file using vb.net to store and retrieve some date from a table Wot am i missing? I see various examples for this but none working with me? Am i supposed to add some references?
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)
I've managed to produce a simple project in vb 2010 express and to publish it onto a cd. I can install the project from the cd and run it successfully on my windows 7 machine where I developed it but trying to install it onto a windows xp machine produces the message:
"An error occurred while downloading a required file...
I want to use a connetction string for connect a databse in sql server express by vb.net? My code is : Cn1.ConnectionString ="Data Source=.SQLEXPRESS;Integrated Security=True;Connect Timeout=30;User Instance=True" but i when open then connection i see this error Cannot open user default database. Login failed. Login failed for user 'Shahab-PCShahab'.
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;
If my understanding is correct, Win 2000 only supports .NET 2.0 Framework. I am using VB2008 Express to write an app that I would like to install but I believe VB2008 Express utilizes the .NET 3.5 Framework.
Is there a way to compile my app so that it only requires the .NET 2.0 Framework? Or, more directly, is there a way to install apps written with VB2008 Express onto PC's running Windows 2000?
I have a VB.NET 2005 WinForm app that accesses a SQL Sever Express database.I use the Microsoft Practices Enterprise library to handle my data access with the following appearing in my app.config file.
I have an application in which i have a database .mdf file in directory which i use a connection string to give a path of to access it, which means without installing sql server i can access database. Connection string below to access this database(.mdf) which placed in the directory.
dim con as sqlconnection = New SqlConnection("Data Source=.SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|Universal_data.mdf;user instance=true")
Now the question is that if i access this .mdf file without installing sql server, i also want to access to this .mdf file on other computer(client) after creating DSN or any other connectivity tool.
Let me know you that when i install sql server 2000 or 2005 i create SA user name and password which i use to create DSN on client computer and give SA username and password in the connection string that successfully works and client get access to sql server, connection string is below.
Dim serv = "MY-LAPTOP" dim con as sqlconnection = new sqlconnection("Data Source=" & serv & ";Initial Catalog=clinic;Persist Security Info=True;User ID=sa")
I only need to know that my application access .mdf file without installing sql server works fine on a single computer, and i want to give access to this .mdf file on other clients without installing sql server on server computer (like i mentioned above paragraph) how will do it.....
i make a connection with SQL server 2005 database using Wizard in Express Edition 2008,I have got data in my text field using dataset , but now I want to execute query for insert, select and update but I don't know my connection vaiable and how to execute query and get data .what kind of connection is this Adodb or oledb etc
Visual Basic 2010 Express, lets the user to add a Local Database with .sdf extension. These databases needs MICROSOFT SQL Server to be created or they can run in the user's pc without any additional software? What are the limit of these databases unlike an external database?
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'm working on a multi user VB.Net windows application with back end as SQL Server 2008 Express. The SQL Server is installed on the intranet network drive. This is the connection string I will be using. Is this correct?
Data Source=.SQLEXPRESS;AttachDbFilename=Q:DatabasePrintDB.mdf;Integrate d Security=True;Connect Timeout=30;User Instance=True
Basically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?
