Pls can someone direct me to where i can get tutorials for MySQL workbench 5.2.34 CE

The OS i'm using is Win7. How do i set the DataDirectory value

Pls guys, i wrote some code which is supposed to be installed on other computers. but when i finished, it could only run on my system, and generates SQL database errors when installed on other systems. the code was written in C#, i used the sql compact server that comes with visual studio 2008.this is how i wrote the connection string:

private static string connectionString()
{
string conString = @"Data Source=|DataDirectory|\electionsoft.sdf;Password=emejulu.4190;Persist Security Info=True";
return conString;
}

   private void openConnection()
   {
       if(con.State == ConnectionState.Closed)
           con.Open();
   }
