    conn.Open()


    comm.CommandText = "Insert into `Eng`.`Eng.info` ('Attendance','Leave','Date') values('" & TextBox1.Text & "', '" & TextBox2.Text & "','" & TextBox3.Text & "')"
    comm.ExecuteNonQuery()

    Hi..

    lets look a simple proc

    create procedure foo @value int out
    as
    set @value=1
    return 2

    then in code

    comm.CommandText = "foo";
    paramValue = comm.CreateParameter();
    paramValue.ParameterName = "@Value";
    paramValue.DbType = DbType.Int32;
    paramValue.Direction = ParameterDirection.Output;
    comm.Parameters.Add(paramValue);

    paramReturn = comm.CreateParameter();
    paramReturn.ParameterName = "@Success";
    paramReturn.DbType = DbType.Int32;
    paramReturn.Direction = ParameterDirection.ReturnValue;
    comm.Parameters.Add(paramReturn);

    comm.ExecuteNonQuery();

    now

    paramValue.Value will equal 1
    paramReturn.Value will equal 2
