Does anyone know of a good article dealing with organizing large class
heirarchies? I've always had trouble with circular dependencies,
global constants and variables, etc. Thanks. 6 1533

Read /Refactoring/ by Martin Fowler. Then add unit tests to all your
behavior, and refactor until you don't have so much excess stuff.
Question: Why is your class hierarchy large? Most are very small. Your
incidental problems suggest that your hierarchy is causing trouble instead
of solving it.
Does every element of your hierarchy actually do something?

If you're using namespaces then, for one approach, browse: http://www.edkirwan.kgbinternet.com/...ac-page10.html
My recommendation is not an article, but a dead-tree book:
"Large-Scale C++ Software Design" by John Lakos:
http://www.amazon.com/gp/product/0201633620/
It's more than 10 years old! Things have changed a lot since then. He
should revise it heavily, if he can. Or other books should be recommended.
One of the good sources of info probably is 'comp.software-eng' newsgroup.
I am expressing caution here because there are other parts of this book
that should essentially be ignored, but they are not really marked as such
and it's not easy to recognize them.

Yes, it's 10 years old and pre-Standard, but from an organizational and
process point of view, it's still quite valid. The specifics of C++
have changed, but not the design, organizational, and process issues.

Actually they have. But it all has really nothing to do with C++...

Hi,
I am currently working on a computer vision system. At the moment I'm adding
support for firewire cameras. Since there is only one firewire system on a
computer, I have writen a firewire manager class as Singleton.
User access to firewire camera objects should only be accessable via
refereces obtained from this manager class. I want to avoid the creation of
more than one camera object accessing the same physical camera.

Hello:
I will be creating 50+ enumerations related to a large number of classes
that span a number of namespaces. I was wondering if there are any "best
practices" when defining enumerations.
Should a single class be created that contains all of a solution's
enumerations? Or should enumerations be defined directly in the files that
contain the related classes? Are there any other design patterns I am
overlooking?

Hello,
I have an ASP.NET webpage that uses an instance of
System.Web.UI.HtmlControls.HtmlInputFile for uploading files to our

filesize limit, once I saw the behavior of the page bombing with files
bigger than 4 MB. So far so good.
But the situation I'm coming across is that there doesn't seem to be

This can be similar to a treecontrol, but I don't need to be able to
