    1. CO¤ C++ is flexible enough to allow you to *easily define* such a feature, e.g. as a macro `NOXNEW` (short for "no exception `new`") as [I show here](http://codepad.org/0jADRP8O). I presume the same is true for Java, but implemented in some different way. However, note by doing this -- returning nullpointer -- you're throwing away any exception information, which is in some cases very undesirable. However, presumably in such cases you simply would not do this. But it's worth being very aware of. Cheers & hth.,

    2. CONote: in the above answer I'm using a macro just to pass a variable number arguments, because Visual C++ 10.0 (the current version) does not yet support variadic templates, and as far as I know they will not be there in Visual C++ 11 either. For full standard C++11 the macro would not be necessary. For that matter, with some library support, e.g. as presented on my main blog, it isn't strictly necessary for C++03 either, although it makes for simpler and more clean usage. Cheers,

    3. COAlso, now that you got me thinking about it, I think that code can be greatly simplified. It's the simplification that's work. And when you done it you wonder how on Earth the original code could be so stupidly complex, but I'm just giving it to you straight, with minimal work. :-)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
