We can't make you know anything, you have to learn. So, given the abundance of documentation and sample code freely available on the internet for your subject, what is keeping you from learning this?

have you tried reading? i know i know how ever thought reading would come in handy... but honestly it comes in handy sometimes.

What? you can't take a little joke without a joke icon warning you beforehand?
You'd better read some MSDN stuff then.

ATL Server Web Service on Vista / IIS 7 and VS2005

without some serious side-effects from Read() to Knowledge, that loop may never terminate...

Hi There !!!
Let's find someone who could help me on this problem.

I have created on VS2005 under Windows Vista a new Visual C++ ATL Server Web Service Project with:
Blob Cache
Session Services (Memory-backed session-state service)
I compiled the project sucessfully. Then, i opened IExplorer and access de URL to generate the WSDL.
The WSDL of the web service was generated with sucsess.

This is my problem:
With this simple and basic project, i changed the configuration properties to support Common Language Runtime Suport, Old Syntax (/clr:oldSyntax)
The compilation of the project was made successfully.
The problem was when i go to access the web service to generate the WSDL via web browser.
I access the URL (something like: http://localhost/ATLWS1/ATLWS1.dll?Handler=GenATLWS1WSDL) on IExplorer, and the web browser hangs and no result is returned.
Just a page indicating that "Internet Explorer cannot display the webpage".

There some dependency or configuration missing to support CLR ?? I tried the same scenario on Windows XP and this works fine.

Should all classes have an interface base class?

Full question: Should every class have one or more interface base classes which are the only means of accessing that class?

Yes would be my answer! My opinion is that no class should ever keep a direct reference to any other class, they should only ever use interfaces, but I'm having trouble persuading some of my colleagues that this is useful.

Does anyone have a link to a persuasive coding standards style document that explains why this is a good idea?

Does anyone disagree with this opinion?

Yes, I do. It is in direct conflict with the KISS Principle[^]

That said, I have certainly utilized that type of design to guarantee proper use of an object. You just need to make sure it is required rather than just being an opinion.

I disagree that following this approach makes things more complicated. You will end up with more code but, looking at any individual class, it makes it much simpler and easier to work out what's going on if you can assume that it will only access other classes via the interfaces it holds and that it will only be accessed via the interfaces it supports.

Of course it does. OOD is a constant effort to find the optimum balance between the flexibility you need and the simplicity you desire.

Or

You don't add design unless you need it.

Requirements rule.

This approach should be considered as just another tool in your toolbox.

When you start slavishly following rules laid down by OO gurus instead of considering whether it's appropriate for the circumstance, then you and your colleagues are in for a world of pain.

Remember, most OO gurus spend most of their time writing books and speaking at conferences and don't actually produce much software, so learn what they can teach, but don't get carried away.

I agree that every case needs to be considered separately when dealing with this type of thing (I'm no OO guru's slave). It's why this is a good idea in principle that I am trying to get across and get agreement on. One can then allow for exceptions and look at individual cases afterwards.

I know I've read convincing information on this before but now I can't find it.

Have you looked at c2.com[^]? If it is considered a conventional best practice you should be able to find cunningham, fowler or beck talking about it.

Also if you do find it please post back here so we can check it out. Thanks.

Really? Do you know these guys and therefore know that they don't work on real world production software? The reason I ask is because the information I have seen, at least for some of the industry leaders I refer to, would seem to contradict your statement.

They might have some good advice (some more so than others - I have many of Beck's books), but what I said was really just a tautology and therefore nothing I can take credit for: if you spend most of your time writing books and speaking at conferences, then you aren't spending most of your time developing software.

So you believe in quantity versus quality? I mean if someone spends any time developing software then some other time writing then they can't know what they are talking about? Perhaps I am completely misunderstanding your statements.

I have not written anything and therefore spent almost all my industry time developing. Even so my experience can't even begin to match the resume of Ward Cunningham[^]
