Answer 1

I think the format of your connection string is a little off. Try:

string strConn = "Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5; 
                  Data Source=C:\\newservice\\UserDataBase\\demo1.sdf;
                  SSCE:Database Password='MyPassword';";

Answer 2

You should probably use the SQLCeConnection Class for this.

string connStr = "Data Source = Test.sdf; Password = <password>";

 SqlCeConnection conn = null;

try {
   conn = new SqlCeConnection(connStr);
   conn.Open();

  SqlCeCommand cmd = conn.CreateCommand();
  cmd.CommandText = "SQL HERE";

  //Change as needed
  cmd.ExecuteNonQuery();

catch {
finally {
  conn.Close();
