Hi,

What i want is :

if any one can Wittie some code for Simple Add/delete/next/previous/update - command by using parameter and stored procedure.

Data connection, function, stored procedure will be in different class( in my picture - under  allclass project)

i want to get idea about how to write 3 tire application - (robust code)- i am following a book, it seems to too complex , so i want a simple robust 3 tire application code.
I have attached another 2 picture- example1 and example2, ( where the writer , he put all functional code, stored procedure in different class)
and he called all those class in main programme.

if you need any explanation, i will try to give more explanation.

bottom line : i want basic robust code for 3 tire application( the example i provided)
