Building a DataGrid Control for Silverlight for Windows Phone #wp7

Av
No Excuse Accounting logo has three elements:
the sircle which represent the context,
the (data)grid which represent the ledger,
and finally the cloud representing both
internet and the tag cloud.
As I´m heavy into accounting, the datagrid is my preferred control. Infact t is one of the three element of my company´s logo. So this article from the Silverlight Show is really good news!

Predicates in Core Data

Av
Database programming is all about filtering and sorting tables linked to each other. According to the book Core Data , «Core Data is Apple’s object graph management and persistency framework for iOS, OS X, watchOS, and tvOS.» In a sense, predicates are an object version of the WHERE clause in SQL. Just like NSFetchRequest represent the FROM clause in SQL. I never have had problems with WHERE and FROM in SQL, but the predicate format strings in Core Data has been quite a struggle for me. I don’t think the struggle is only my fault. Predicates should clearly be thought, at least to me, as a method of writing WHERE clauses. Here is some notes from tutplus’ Core Data and Swift: Relationships and More Fetching : let predicate = NSPredicate(format: "%K == %@", "last", "Doe") The predicate format string uses %K (K stands for Key) for the property name and %@ for the value. let predicate = NSPredicate(format: "%K >= %i", ...

Totenbanken, en del av det jeg kaller “Eika” samarbeidet, er en bank jeg beundrer. Historisk og bankfaglig er Eika-bankene av de beste. Derfor tar jeg også hardt i for å få de framover på IT siden… Totenbanken, dere burde få oss til å øke sikkerheten i maskinene våre, ikke tvinge oss til å redusere den! Etter noen timer med arbeid og ingen lyd fra deres support, bør du ta deg tid til å høre min historie: I går ringte kona mi fordi hun ikke kom inn i nettbanken. På nytt kom den stupide advarselen om at hun ikke hadde Java og måtte oppdatere denne ved å trykke på Java bildet. Som sist, står det der at Apple har egen Java og at du skal kjøre program-oppgradering. Så tilbake til start.  Jeg ante uråd, og prøvde hos meg. Samme problem. Så jeg ba henne la meg ta det opp med Terra idag, så skulle jeg finne en løsning. Og jeg sa dette med friskt minne om all venlig men ukynding support vi hadde fått før. I dag tok jeg fatt på om mulig finne feilen. Min Mac hadde ...
