API to create table, stored procedure, etc.

In SQL Manager I can right click on a stored procedure, table, etc. and I am presented with a list of options one of which is "Create >". Clicking this I can get a script that will create the respective stored procedure or table and write the create script to the clipboard, a file, or an SQL query window. I want to automate this to essentially selectively "back up" our data base by creating one large script that will create the tables and stored procedures from the database. Is there an API, tool, or library call that I can get access to the code that implements these menu selections?

Thank you.

Yes. Look up the SMO reference in BOL. It has all of the capabilities and the full class library to do what you need.
