I just started to learn C#, and currently trying to create a simple program that read 1 row of data from SQLite database.
I've successfully created the program, but i still have to refer to the .db file with full address like :
SQLiteConnection("Data Source=C:/Users/../SQLiteStudio/dbs/mk_ii.db; Version=3;")
But this way, the .db won't be included when i create an installer. I want to make it something like when i add an image to my Solution Explorer, i can use short address like :
res/img/logo.png --i also have copy of .db file in res/ folder
So, is there any way to include the .db file to my project? I've tried to read current directory and using |DataDirectory|, but all of those referred to the .exe file's active folder, and didn't work when i debugging since when debugging the .exe file have different directory than the project directory.
For a note, i'm using VS Community 2015 and System.Data.SQLite. Also i've tried added the .db file to Solution Explorer, but i can't seem to access through it.
Include your database file in your project. Set the type to Content, that will make sure the file is copied to your output directory. Use relative path in connection string.

I have a WPF project that is now finished, and I want to publish the app into an installer that other people can use.
When I publish the project, the project compiles into setup.exe, but on install the folders that I have do not get included.
I've been reading the guides, and made sure to include the files inside the folders as Content or a Resource. I've also made sure they are always copied. When some of my files are copied, they have a .deploy extension, and I need it to be an .xml in order for some function to read them. Images that I have in the app load fine however.
What do I need to do to have my custom files be EXACTlY as they are, xml as xml, txt as txt and so on. Also I have some empty folders, like this TempCF that I use at some point. Do i need to create it via code?
If you go to Project->Properties->Publish->Install Mode and Settings->Options->Deployment in Visual Studio, there is a "Use ".deploy" file extension" option that you can untick to get rid of the .deploy extension being added to your published files:
Empty project folders are not included in the output. Either put a dummy content file in them or create the folder dynamically as needed during runtime.

You could try to use the following methods to add the files in your program to the installation package so that you can have the files you need in your installation path. If I misunderstood your question, please let me know.
The steps are as follows:
1.Right-click on the Setup project and select View -> File System
2.In the File System page, right-click the Application Folder (File System on target Machine) and select Add->Folder(named User's Application Data ) -> File…-> find the file under your project and select the file you need.
Such as:
3.Right-click the Setup project.
Install your setup package.
You can find the files you added in your installation path.
The result is like the picture below:
I want to embed the SQLite database into my C# windows form app (.exe) so I can give a very non-tech savvy client just the .exe file and nothing else. The database is read-write and I need to access its path for the DataSource like so:
SQLconnect = new SQLiteConnection("DataSource=" + path + ";Version=3;Compress=True;");
I also tried saving the database to a folder on Desktop but SQLiteConnection.CreateFile(path) seems to fail because if I put the .exe file outside the bin/debug folder, .exe does not open at all (but it creates the necessary folder on Desktop).
But as long as it is in the bin/debug, it creates the database file and creates the tables and .exe works perfectly. There are no errors raised at any point in the application.
To include the SQLite dlls you will have to modify the property of the reference and mark it as Embedded Resource. You will probably have to use ILMerge See this.
You cannot embed the database. So, you have the following two choices :
You can create In-Memory/Temporary database.
var connection = new SQLiteConnection("Data Source=:memory:");
Create the database on the go. On your application startup, you can create and seed the database. See this.
In the first installation in my WPF application I checked if the SQL database for my application exist or not, If not the application restore it from .bak SQL file.
When I publish my application I can't attach (Embed) the .bak file.
How can I do that ?
Thanks in advance

Well .. I got the solution :
One good way of doing this is:
Create a folder under the app in VS name e.g. "datafiles"
Add all files to that folder using Add as link in the dialog box after selecting Add existing item on the folder
Mark all files as Copy if newer (Copy to output directory property)
Make sure the build action is content
--> when you publish the files will be put in that folder and be a part of the application installation
Good luck!

I'm trying to publish a project which needs some data which is stored in a .txt file.
The file is currently located in bin\Debug.
The Path for the Streamreader is relative using Applicaton.StartupPath.
I added the .txt file to the solution explorer, but somehow i get a bad path error message every time i try to start the published setup.
How do I publish my Project with the needed .txt File?
You have various ways of achieving this.
The txt file included in the solution file will have a property called Build Action. Change it to Content and it should be published with your deployments.
You can add it to your resources, but then you will need to access it differently.
Add it to your installation package
I want to embed a PDF file (which is basically have Product details, Release notes) and wants to open that file from menu bar. What would be the best approach. I need to use this file in installer also. So i'm looking for an approach in which file will be moved to BIN on compilation and from there installer can access that file.
IDEAS ...
Add the file to the project the builds the EXE (use Add existing file in visual studio). Then right click on the file in visual studio, go to properties, and verify that the build action is "Content" and the copy to output directory is "Always" or "If newer" (whichever suits you).
Then this file will always be copied to the same directory where the EXE resides and your application will be able to access it because it's always in the application's directory.
If the installer just takes the BIN directory then it will also be able to access it because the file will reside in the BIN directory.
Have fun!
Finally i did it in following way:
a. We've a folder which contains notes.pdf (used by installshield).
b. Created a pre build command to copy the pdf file from installshield folder to output directory.
c. use process.start("notes.pdf"); to open the file. As it would look in bin directory first for pdf file and we've already copied it there.
It worked for both Installer version and running application from code.
