Hello Everyone,

In my C# windows app using sqlite database, i observed each time i run the application and insert new records into the database, the records will be saved as long as the application is still running, but when i stopped the application, the records will be wiped out(deleted) from the database while using this connection string:

XML

<add name="PITADatabaseConnectionString" connectionString="Data Source=|DataDirectory|\App_Data\PITApplication.SQLite3Db; Version=3;" providerName="System.Data.Sqlite" />

When i change the connection string to:

XML

<add name="PITADatabaseConnectionString" connectionString="Data Source=C:\SqLite\Gui\SQLiteStudio\PITApplication.SQLite3Db; Version=3;"
      providerName="System.Data.Sqlite" />

and save new records, it will be saved permanently and not deleted. I don't know what the issue is, i added the database to a folder in my application through add new items context menu, after adding the database to my application i set Build Action property to Content, and Copy to output directory property to Copy always.

i will appreciate your kind assistance.

What I have tried:

i have used this connection string:

<add name="PITADatabaseConnectionString" connectionString="Data Source=|DataDirectory|\App_Data\PITApplication.SQLite3Db; Version=3;" providerName="System.Data.Sqlite" />

Do you use transactions?

yes, i am using transaction to save the records, is that the issue?

It is possible. If the transaction is not (yet) committed when you stop the application, the database will perform a ROLLBACK and thus you miss data.

Most likely the file is being recreated somehow in your IDE or elsewhere in your application.

how do i know where the record is being recreated?

No idea, it is your project. you need to do some debugging of your application and also monitor where and when your files are accessed and updated.

Maybe the 'insert's have not been 'commit'ted.

I was able to resolve this issue by going to application properties window, under settings i added a connection string that points to the connection string in the app.config file. I also set the copy to output directory property of the database to copy if newer, and the issue was resolved, thanks to everyone that contributed.
