Finding the commonalities and variabilities within a system, and expressing them, forms the heart of design.

Procedural programming is often seen as "old school," outdated and useless in modern software design, but the design paradigm still shows up in a surprising number of places-including the compiler and MSBuild.
MSDN Magazine November 2010
In this series we've examined procedural and structural programming, objects, and metaobjects. Now let's take a look at generics and put them to work as an example of parametric polymorphism in action.

After tackling NoSQL, Ted Neward turns back to the relational world of SQL-SQLite, that is. Learn all about the lightweight, embedded database whose running footprint can be as small as one file installed in a client file system.

I have a list of "Faults" - this contains the Shop Number that the fault was logged against (which is a lookup column to the "Shops" list), who logged the fault ("Created By") and the details of the fault ("Title").
If I add the list as a web part and filter by Created By, it works perfectly - I get multiple entries in the list for all faults logged by a certain person.
However, if I filter by a Shop Number - I only get a handful of entries in the list, going back a few days - anything older than that is simply not there.
Yet if I go to the main page for the Faults List (AllItems.aspx) and change to Datasheet view - the filter works perfectly, I can see EVERY entry for a particular Shop when filtering on Shop Number.
Any ideas? It only seems to happen when using a Web part OR a DFWP - as a result, I can't pass the Shop Number as a filter parameter to it, nor can the users see a complete history of faults when viewing individual shops.
I've no idea what has changed recently, other than deletng some custom views we had created in the Faults list - could this have caused a problem? Can the Faults list be "reset" somehow without losing any data? To clarify - it's ONLY happenning when the
list is viewed as a web part of DFWP, when it's viewed in Datasheet m
One of our departments has a relatively large library with folders, sub-folders and sub-sub folders. They want to be able to add a web part to one of their pages that displays items only within a sub-sub folder, rather than beginning at the root level of
How might we customize the part so that it starts its display at the sub-sub folder we need?
