Hi
I am considering using LLBL O/R mapper/data-access tier generator. Until
now I have been using CodeSmith "home made" templates for DAL classes
and store procedures generation.
I have also noticed that LLBL code does not use datasets, and as I have
been using datasets for databinding operations I wonder how is it
achieved if using LLBL.
Anyhow any hints/experiences/dont's in using LLBL is appreciated.

Fine, not more then that. It have most of things needed, however OpenSource
is OpenSource - It does not "Product" yet

Are you discussing the old LLBLGen 1.x dal generator or LLBLGen Pro, the O/R
mapper ? :) If it's the latter, datasets are not used because an O/R mapper
focusses on single objects, not collections of objects. This means that you
need classes which represent entities, not a dataset with 1 row representing
an entity. If you have more questions, let me know :)

I am considering purchasing LLBLGen Pro, but I'm bit worried about
possible issues in relying entirely on LLBLGen. One of features that I
am using heavily is databinding my forms to related tables in dataset
(parent-child relations).
Is it possible to achieve similar functionalities with LLBL? aa*@bbb.hr wrote: Frans Bouma [C# MVP] wrote:

Sure, just bind an entity collection to a grid, with relations, so you can
navigate through related objects if you want, like you bind a collection of
Order objects to a grid. Every order object automatically has a property
OrderDetails which exposes a collection of OrderDetail objects related to
that order. You can bind that collection to a detail grid for example. See
the northwind example project available in the demo download section. :) (be
sure to have the demo installed to compile the code).

Hi,
When list comprehension was added to the language, I had a lot of
trouble understanding it but now that I am familiar with it, I am not
sure how I programmed in Python without it.
Now I see that generator expressions have been added to the language
with 2.4 and I question the need for it. I know that it allows for lazy
evaluation...

Ok, we've added list comprehensions to the language, and seen that
they were good. We've added generator expressions to the language, and
seen that they were good as well.
I'm left a bit confused, though - when would I use a list comp instead
of a generator expression if I'm going to require 2.4 anyway?
Thanks,
<mike
