I have an application where the entire database is implemented in memory using a stl-map for each table in the database.

Clients are able to contact th...
I have implemented a UIScrollView on the iPhone that contains 100 image slots which I fill only the currently visible page, the one before it, and the one after it as the user scrolls.

I have an access report that generates 36505 pages (un filtered, and about half of each page is taken up by group headers and page headers) , though the footer at the bottom of the report page says "36505 of -29031".

I'm passing the grid request to a web service which accepts an int fo...
