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.
View 7 RepliesI 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.
View 5 RepliesBasically 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?
i am new with SQL server 2005 and visual studio 2008.how do i connect the forms and the tables in the database
View 4 RepliesI have an application that accesses a sql server 2008 database. The server and database is stored on my local harddrive and I would like to learn to scale this up to having multiple users in our office access the application which I will i deploy on a server. For now the database will stay on my pc until I am ready to put it on a dedicated server for myself but for now how do I allow the application still to access my database without allowing anyone direct access to my server or my pc drive. Here is my current connection string:

May I ask a question to you all.I have vb.net project that generate sales report from SQL Server Database.I changed SQL Server 2005 Express to SQL Server 2005 Standard Edition.
After that my program can't run properly and every time I got Time Out Expire message.
That program work properly with SQL Server 2005 Express.May I request suggestion how to fix this.
When a user click the .msi, i want a folder called "Your Files", which comes with two small images by default, to be created in C:UsersYourNameDocuments. In short, MyDocuments.
What i did is put the following code in program.cs:
string myDocuments = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
string downloadArea = System.IO.Path.Combine(myDocuments, "Your Files");
System.IO.Directory.CreateDirectory(downloadArea);
Just before:
Application.Run(new mainForm());
The problem is, this folder will be created every time the user runs the application which is not a good solution, also in this case there is no place to load the two images so it can be loaded while the folder is created. I want the folder to be created once preferably while installing the application, so even when i uninstall the folder "Your Files" and its sub files be deleted automatically along with the program files. I tried to do it via Setup Project, but i couldn't.
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?
View 4 RepliesHere 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 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.

View 2 Replies3 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.
View 1 RepliesI have just installed VB.NET 2003 and I am trying to manage some databases using SQL Server 2005 Express.When I try accessing the database via the data connection tab, I get the following message.
Quote: You have connected to a version of SQL Server later than SQL Server 2000. The version of Visual Studio or Access that you are using was released before the version of SQL Server to which you are connected. For this reason, you might encounter problems.
Please check with Microsoft to see if there is a service pack that you should apply to Visual Studio or Office in order to get support for the version of SQL Server to which you are connected.You can continue but any new object types might not be enumerated, and it will not be possible to save any objects or database diagrams that you create using the Visual Database Tools.I can not add tables or manage data fields. Does anyone know how to get the patch referred to in the message above? I can not find it via google or this forum.
am working on a project and am using sql server 2005 express as my database server, the problem is i can;t connect to the sql server from any machine on my local network (windows).
Below is my connection string
con.ConnectionString = "Data Source=webserver1SQLEXPRESS;AttachDbFilename='C:POSM_DB.mdf';Integrated Security=True;Connect Timeout=30;User Instance=True;"
It works all right on the development machine but not on network, i think it has something to do with the network.
I have a client that has the basic database on a server(sql server 2005 express database) and wants to work on his laptop from his home, so i guess that i can install the software on his laptop but how will the 2 databases be synchronized, having same data. the synchronization will be made once a day in the morning when he returns to his office. How can this be accomplished?

i have a project and i used NSIS to create a Setup file. I am able to install it to my system but some parts of the program do not work (and they work when i run my project in VB). For example i have a Back Up option that creates a back up but this does not work when i run the application via the installation file. Probably it has something to do with the directories?
If System.IO.Directory.Exists(CurDirectory + "Backup Folder") = False Then
System.IO.Directory.CreateDirectory(CurDirectory + "Backup Folder")
End If
how can i make it work from the installation file? Do i need to copy something somewhere?

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?
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)
