sir my program is a pls help me..:(
thanks in advance..

I've always used the following method for database operations. I split the actual database access into two methods: ExecuteQuery and ExecuteNonQuery. In your case, if you're trying to write to the database, you would want to execute a non-query.

private static void ExecuteNonQuery(OleDbCommand cmd)
        OleDbConnection dbConnection = new OleDbConnection(connection_string);

        cmd.Connection = dbConnection;

Putting it in it's own method let's you use it for any SQL statements that might need to execute a non-query. Then, in your save button code, you might want to do something like the following:

public static void insertRow(string value)
        OleDbCommand cmd = new OleDbCommand();
        cmd.CommandType = CommandType.Text;
        cmd.CommandText = "INSERT INTO table_name(field_name) VALUES([@value]);";

        cmd.Parameters.AddWithValue("@value", value);


Also, if you add a "using" clause for System.Data.OleDb, you wouldn't have to write so much in your code for those objects.
