I have created a visual studio app with an access database and connected the two using a connection string. The database is in the same folder that the solution is in.
Is this how this should be set up to allow the app to run on a different system? Or is there something else I need to do with the database when creating the installer? (assuming the other systems that it will run on WILL have access and the correct .NET framework installed).

I want to create a setup file from a C# project in Visual Studio 2015 that attaches a SQL server database, and I want to run that setup file on another system and run without Visual Studio and SQL server
You are have two solutions
You should develop your application with SQL express on .NET framework or after develop with SQL Server change connection string from SQL Server to SQL express and rebuild it, be sure you create initialize DbContext class to set some data for run your application at first time with base and default data. [Such as application users and rolls and groups].
You should develop your application with dependency injection pattern [Microsoft Unity, IoC] then modify or replace one interface to change your developed application database.
Then Right click on project in solution explorer and publish it and give to customer.
The customer server has to run some kind of SQL Server if you want the SQL data to be accessed somehow. One thing you can do is to deploy your C# project with Visual Studio, export all needed tables (including their data if you want that) from whatever server you are using (for example MySQL) into a .sql file and pack everything, including instructions on how to install the sql server and your application, into a zip file and ship it to your customer.
What I do with my website application is, that I include a .bat that fetches everything from my git repository, deploys my web application on an existing IIS-Server on the current computer (with 'aspnet_compiler -f -c -u -errorstack -v /web -p "source directory" -d "target directory"' and 'iisreset /noforce') and automatically imports the SQL tables to an existing MySQL Server (with mysql --host=localhost --user=user --password=password --database=database < Backup.sql).
Sorry for that general answer, but you're question really wasn't that precise.
If you want to create a setup of your project then,
Click on Build on the top of visual studio tab and then click on Publish "yourprojectname" click on it and your setup file will be ready.
Hope this helps you
Use LocalDB,
(no need to at least open sql server management studio)
When you create Setup file add prerequisite
.net framework version
sql server (2012 -2019) express localdb
Add connection string correctly!
So from what I can gather you are looking for an easy way to distribute your database schema to clients, is that correct? If so then I don't see how you could intend to run the setup without SQL Server (without VS is fine though).
Assuming my assumption is the case then I think you need to think about a solution that will handle schema upgrades as your project develops, in which case it's essential that you move to Database Projects in Visual Studio as it will handle upgrading the schema automatically, and allow you to run change scripts for the things it can't do automatically (like when you've changed a column type or removed a column etc).
Here are some links to get you started:
Working with Database Projects (MSDN)
Introducting Database Projects for Visual Studio (youtube)
Using the knowledge that CSPROJ files are just MSBUILD scripts at the end of the day you can now publish the database project during whatever your installation/upgrade system is using msbuild which is included in the .NET framework i.e. you don't need Visual Studio.
This is by far the most robust and reliable way of dealing with database deployment. I would advise staying well clear of automated tools like Redgate, they do a great job for small projects that maybe get used in an office etc but for professional software development you need more guarantees and control.
You can try this, with Octopus deploy.
Or, you can try with Code First migration
Have you already existing database, or development starts now?
I have an application written in C# (VS 2013) which is connecting to a database using MySQL. Is it possible to run this program on another computer without installing MySQL, which has VS 2010. i wish to run the application with .exe file, if that is possible?
Furthermore, the application is about collecting information about Academic/Recruitment Tests through "forms" so the information is updated in the database also.
Thank-you
I don't know if I got you right, but you can run the compiled EXE file on every system that offers the .NET version specified in your project settings.
What is the easiest way to deploy a c# winforms application that uses an ms-access database? Using Visual Studio 2010's Installer, I cannot seem to get the database deployed to a common directory for all users of the PC to access it.
Searching the web, I have found tons of issues, but no simple solutions.
you can't find a directory that can be accessed by all users of the PC? maybe you can deploy the database to a special directory using the special enum named Environment.SpecialFolder, such as "CommonApplicationData" or "CommonProgramFiles".
I developed a C#.NET desktop application that uses MySQL as a back-end. What I want is that when user installs the application, the MySQL server should automatically installed and username and password are automatically set and the database is restored from a SQL Dump file automatically by the installer. I am using setup project in visual studio to create installer. Is it possible to perform this operation in an installer?? If yes then please tell how to perform these operations??
I'm afraid you can't unless your database server is MSSQL. Better create a separate installation between your application and the database server.
I fixed the issue like This
tack all the Backup of the MySql Data base
Created Console Utility which store the database in console Application
By Using Heat.exe added the Sql File And .Exe file to the Project (Wix)
Use the Custom Action Call the Exe Which Store the Database Backup
Delete the Exe and Sql File from the Install location
I'm using Visual Studio 2005. I create a project, not Web Project, just Windows application.
I remember that Access Database File can be added into a project. I don't need connection to server, data can be retrieved. And I want to do the same thing with SQL Database file.
I did the following steps:
Right-click on project.
Choose Add An Existing Item
Browse for *.mdf file.
DataSource Config Wizard appears and it displays this Message
An error occurred while retrieving the information from the database:
Failed to generate a user instance of SQL Server due to a failure int starting the process for the user instance. The connection will be closed.
I need help to add mdf file into my project.
To start with, and MDF file can be read only by an instance of SQL Server. If you deploy MDFs, then your application must either connect to a SQL Server provided by your end-user during setup, or it must deploy its own instance, in the later case a SQL Server Express Edition instance. See How to: Install SQL Server Express. With Visual Studio 2008 you can add a prerequisite to your own application setup MSI, see "Installing" the SQL Server 2008 Express ClickOnce Bootstrapper for Visual Studio 2008 SP1.
A second issue is that, despite the wide belief of the contrary, distributing the MDF alone without the LDF can land you into a world of pain. You can end up distributing an inconsistent MDF that needs the LDF to finish recovery and get into a consistent state.
But a more serious issue is your plan to deploy binaries (MDFs) instead of scripts for database deployment. This is doomed to fail. As soon as you'll plan to release v. 1.1 of your application you'll face the non-trivial problem of how to replace the user MDF (which now contains data added by the user) with your new MDF. This is why is much much better to deploy upgrade scripts always, and forget about the MDF in your project.
You can read from an Access file (*.mdb) in your app without any other requirements because the core Jet engine used by Access is included as part of Windows — it's built in. Sql Server is not included as part of Windows, and so you cannot use an *.mdf file in your app unless Sql Server has been installed and you have appropriate permissions for it.
It is possible to distribute either Sql Server Express Edition or Sql Server Compact Edition (recommended) with your app. Another option is SqlLite, which has a fully-managed database engine available.
An .MDF is a sql server DB, not MS Access. MS access is .MDB. You cannot read an .MDF on its own. It needs a log file (.LDF) as well. If you attach it to your local instance, it will create a new one for you. You can then connect to that DB.
To solve deployement problem (Updated version of your .mdf file and Code), you can have a utility in your application which can create .xls file of every table(Backup your database) which you used in your application. Now you can easly import those .xls file in SQL Server and create new version of .mdf file and attach same file in latest code.Now new release of your app ready to deploye..!
