Hi all,
I'm hoping that some of you clever chaps could offer me some advice on code
reuse.
You see, whenever I make applications, I typically only find very limited
scope for code reuse. I also only find limited use for inheritance. For
example, the various types of users that my system might have to deal with.
I'm wondering if anyone could give me some tips on how to identify areas of
my design that could be reusable, where I can use inheritance and where to
use interfaces. I've read all the books that talk about why these things are
important but very few of them show you how to do it in the real world.
If anyone could point me to some online resources on this then that would be
great. I could also do with a couple of books on how to spot reusable
aspects of my designs and so on.
Any help would be great
Thanks all
Simon

Hi, Simon
it's nice question because it is nearly same as "how can I live a fruitful
life" :-) No joking. Seriously.
As I see it, high-level design questions like this one are not in general
public domain because
- every person sees the world a bit differently from any another - to put it
mildly
- to prepare foundation for future is like trying to predict the future
- everything evolves and good today is bad tomorrow
However, I don't mean I know better. I would suggest to check http://hillside.net/patterns/DPBook/DPBook.html and possibly http://c2.com/cgi/wiki?HistoryOfPatterns, where you can see some of most
well-known names and references.

Simon... There are many opportunities for code reuse, but Inheritance
may be
over hyped. See Bloch:
Favor composition over inheritance
Effective Java Bloch
As for interfaces, I have some guidelines here:

Jeff

Hi,
I'm evaluating Visual Studio and the .NET concept for his company, which
is currently using Borland C++ Builder.
Now I tried to create components/controls etc. in .NET and I can reuse
it very easily by adding the control to the toolbox. This is great and
more 'safe' to do than in Borland.
But... although I'm nice, I'm not so nice...

I've noticed that the trend these days is to declare variables in the
middle of code instead of at the top. What is the advantage of this?
It seems like it makes it hard to reuse variables.

Hi all guys,
As an embeded programmer with five year C experience,
I did read many great books related with design, coding,
test,debug,algorithms, compiler, design, os, pm and others.
I always dream to achieve a refined and reusable design and
implementation.
I am very interested with code reuse.

I remember reading on parashift recently, that "Composition is for code
reuse, inheritance is for flexibility" see
(http://www.parashift.com/c++-faq-lite/smalltalk.html#faq-30.4)
This confused me somewhat as I have always thought you get code reuse
"for free" with inheritance. Am I missing something?. Will someone care
to explain ??

I am just trying to get to grips with C# and OOP, and one of the benefits
would seem to be code reuse. However I am not sure where to draw the line. I
have the following section of code:
if (ev.locationList != null)
{
//isListNull = true ensures that we do not recheck the list
every time we add a new item
bool isListNull = false;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
