I am trying to use Sqlite database in my C# project and I done this well in IDE. My problem is when I make setup package for my project and I install it, the program can't access to the sqlite database. Also I know it is because the user doesn't have permission to access file, and when I run program as administrator the problem is solved.
My questions is, how can I use sqlite database in my project so that the program to be executed without administrator permission after installation?
I am using Installshield Limited Edition to deploy my project.
I think that if you wrap the database in an installer, it will extract to Program Files, in which you might have problems accessing for write access with certain users.
InstallShield should have a special pseudo folder to pop the datafile in AppData. You'll also need to change your program so that it expects to find the database there.
I can't quite remember the details I'm afraid.

I'm fairly new to windows forms and I was recently tasked with creating a simple software which will be deployed by USB drives to other companies. I made this software so during first run I check for a config.xml file. If it doesn't exist, I will send the user to a form to configure their first time setup. Next time I run the program, it skips this step since the config.xml file is found with its values. The problem is when I debugged this, I found the config.xml file alongside the executable, however when I ran this on a different computer, it stored it into the appdata virtual store. I read up on this and found out it has to do with write permissions.
Is there any way I can get around this without prompting the user to do anything extra on their part such as run as administrator? I also plan on saving the resulting reports generated by the use of this program and was hoping I can have XML files which can be easily found within the application folder.
*Note, I am aware of the built-in settings system but this also stores into appdata and if the executable is moved to another directly, it loses sight of that config and wants to create another.
EDIT : Please be aware I am trying to AVOID writing to the AppData folder. The software is packaged with Visual Studio Installer - Setup Project. A msi file is created which stores the application in C:\Program Files (x86)\\. Inside this directory I have the executable, the exe.config file which is generated, and any DLLs needed. This is the folder I am trying to also store the config.xml file but due to some windows magic, the code thinks its storing it here but in reality it is being stored in the virtualStore folder located in AppData.
Have you thought of using the C:\ most computers have this unlocked. alternitively use Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
the AppData folder is stored in the username space and requires no permission. (just remember to create a folder for your program to avoid conflicts)
It is a known issue due to security concerns that write permissions are limited.
More can be learned here.
Since no one was able to answer this, I will post my solution. Instead of packaging the solution using Visual Studio Installer tools. I install the application by copying the resulting executable from the build. This version of the application has write permissions that would have not existed if the application was installed using the resulting .msi from the Installer tools.
I'm facing severe issue while creating .exe file of my C# WinForms Application using Advanced Installer Architect. I'm not getting to know how exactly to create an exe file with MSSQL Database.
Kindly help me solve the issues:
I want MSSQL Database to be installed automatically on the system if it doesn't exist.
I want to know what should be the datasource in my application while building it.
I also want the tables should be created automatically t the now installed MSSQL Server Database.
Kindly help me with this issue!
If you are using Visual Studio then you already have exe created.
visual studio is much smarter. and its creating exe every time we run our win form application.
you can find exe in your projectfolder/bin/debug/yourexe.exe
I have deployed a Windows Forms Application (Visual Studio 2013 C#) to a file share and will get my users to run the app from this file share. The app uses Entity Framework 6 and works fine from the file share but there is a delaying in loading the EntityFramework.dll during execution for the first time.
Is it possible to move just this dll from the file share to the local pc and tell the app to use it from the local pc?
As #tede24 stated, before trying to solve this problem, make sure EntityFramework.dll is actually your problem.
Once you make sure it is, here are the options I can think of:
1) Use ClickOnce
ClickOnce is not popular, but it still seems to be the preferred way for deploying intranet applications. Yes, it supports version checking and auto updates.
2) Use some sort of XCopy installation
You can create a batch/PowerShell to copy the application content locally from your intranet. If you want to go futher, you can even verify whether the version is the latest before launching.
3) Try putting EntityFramework in the GAC on the client machine (not recommended)
EntityFramework is not meant to be GACed, but you can still try to do that. I would strongly avoid it because of dependencies and update problems you might run into.
I know this subject was discussed here before, but it looks like there are several opinions.
My C# App is connected to a Database using MySQL, I created an installer for it and tried to run it on another PC.
The program didn't work.
How can I make it run on others PCs?
How to include the MySQL Database with my installation package?
If I used the localDatabase in visual Studio 2013 instead of MySQL will this solve my issue and make the application run on other PCs?
When I use the localDatabase; a (*.mdf) file is copied to the debug folder, if I just included this file in the installation package, will it be enough?
I just finished writing a large program that uses a pretty large database file. In the past, when I finished writing programs, I just uploaded the .exe file to my website and sent the link to whoever wanted to use it, but now there's also a database file to include..
Is there a way to "wrap" the database file in the .exe? If not, how can I release my program so that the user only has to download one file? I've never created an installer, nor do I really know how.. I've only ever just uploaded .exe files :).
Any help would be appreciated. Excuse my inexperience :P.
The program is programmed in C#, and the database file is in .mdf format (I am running SQL Server 2008). I'd be happy to provide any more details. :)
Instead of bundling the entire database, you should make the application know how to create the database. A simple way is to create a script for the entire database in SQL Server Management Studio. Then include the script (probably after you've made some adjustments to it) in the exe file as a resource file.
A better approach than rolling your own solution is to use a data access framework such as EF Code First with Migrations that has database creation and upgrade support built oin.
You can make simple setups from visual studio (Create new setup project). If you need more advanced features, have a look at Windows Xml installer
You can include the free Sql Server Express so your users don't have to buy a license of SQL server. If you want to go through the effort of building an .msi installer, I believe you can do SQL-server - specific actions.
On the other hand, if you have a small amount of data, you might consider using the filtering features of Dataset instead of relying on SQL server.
Edit: Microsoft has a new SqlServer 2012 LocalDB that might be interesting:
New to the SQL Server® Express family, LocalDB is a lightweight
version of Express that has the same programmability features, yet
runs in user mode and has a fast, zero-configuration installation and
short list of pre-requisites. Use this if you need a simple way to
create and work with databases from code. It can be bundled with
Visual Studio, other Database Development tools or embedded with an
application that needs local databases.
