            SQLiteDataReader sqlite_datareader;

            // create a new database connection:
            sqlite_conn = new SQLiteConnection("Data Source=dbDemo.db;Version=3;New=True;Compress=True;");

            // open the connection:
            sqlite_conn.Open();

            // create a new SQL command:
            sqlite_cmd = sqlite_conn.CreateCommand();
 
        }
    }
}


by click button after that it gets like this ===

error

You copied your snippet from http://adodotnetsqlite.sourceforge.net/documentation/csharp_example.php but fail to understand it. Work thru it, try to understand hwat it does!

The error is ovbious, you're not having the System.Data.SQLite.dll saved inside your library folder (bin).

You should make sure that you're having this library file (.dll) inside the binary folder. So that you can use it. Make sure read/write permissions are allowed and also, that you're calling the exact name of the file.

error in this

private void insertconnect_Click(object sender, EventArgs e)
{
// [snip] - As C# is purely object-oriented the following lines must be put into a class:

// We use these three SQLite objects:
SQLiteConnection sqlite_conn;
SQLiteCommand sqlite_cmd;
SQLiteDataReader sqlite_datareader;



sqlite_conn = new SQLiteConnection(); // Create an instance of the object
sqlite_conn.ConnectionString = "Data Source=c:\\eminosoft.db;Version=3;New=True;Compress=True;"; // Set the ConnectionString
sqlite_conn.Open(); // Open the connection. Now you can fire SQL-Queries

// create a new SQL command:
sqlite_cmd = sqlite_conn.CreateCommand();

}

Oh dear... Did you place the database file to Data Source=c:\\eminosoft.db on the target computer? By the way, that is a very very bad place for a database file. SQLite database files are often stored in the user profile; c:\programdata\YourCompany\YourApplication\YourDatabaseFile.db can be an appropriate alternative.
