One of my Les Paul's has that option. The Black Beauty pickups let you switch back and forth between single coil and double coil. I won't claim it sounds like a strat or tele in single coil mode, but it does sound sweet.
Will get back to this thread later time allowing...

Sweet.
I've always wanted to go more Les Paul, but having come from a Van Halen/Vai rock type background - I've always ended up buying guitars with Floyd Rose style trems. Mind you, as I'm getting older (and a bit more mellow), perhaps it's time for me to experiment with a fuller sound.

Well, I don't see it this way. I'm not a purist. It doesn't have to be exactly right the first time. Not only in design, and development of code, but also in design and development of paradigms its an iterative process. I'm not gonna choose to throw the baby out with the bathwater here.
Like I said before, which you seem to be selectively leaving out of the discussion is that I personally prefer a blended approach and don't see this as competition between procedural and object orientation, but rather as complimenting themes to be used where useful.
So, I enjoy the current wave. I'm productive in it, and can think fluidly when designing a system.

No sell. Software is a better match to the machines that we build using tools. Therefore how we use tools is not germane to your "procedural" point. Software is more comparable with an automobile or an aircraft carrier than tools. You are just wrong... as usual.

No, you are ignoring that those are machines. Machines are used by people as are tools but they are vastly different of course. Ignore it if you like but then you have the resultant flawed analysis and bad decisions based on it as a consequence.

that's your original argument? Whatever... I quoted what I was replying to, here is another:

He seems to think that because humans use a procedural approach to using a tool, that it follows a tool should be coded, and follow, the same procedural method. Not so IMHO.
This approach may be true for simple tasks for programs to follow, but OOP developed out of the need to develop more complex tools.

It is a tool. The problem is that you're not looking deep enough into the word processor. As with any tool, say an electric drill, it's made up of parts that interact with each other in very specific ways to accomplish a function of the drill. Some parts are interchangable with other drills to modify their function in some way.
Animals and plants are built the same way. Out of many smaller pieces that interact in specific ways to give a more complex organism life and various functionalities.
The adaptability of humans is a testament to such a concept. Human's weren't made with wings, so they couldn't fly. Add the classes called MetalWings and a class derived from IThrust and you've enhanced the abilities of the Human class so he/she can fly, and you done it without modifying the code for Human.
Your argument is flawed because you're ignoring the fact that all tools are made up of smaller pieces, that, individually, are interchangable and couldn't do any part of the task the tool was designed for by itself. The interaction of objects is what provides the functionality, not the objects themselves.

They are. They are also like tools as you suggest and Machines as I stated, they are also like a pair of shoes or a bar of soap... so what?! There are many things that programs are "like" but you are trying to limit them to being "exactly" like a hammer and therefore we should only think of them from that perspective.
Perhaps the software you have experience with is more like a hammer than an Aircraft carrier but that is not my experience and therefore you are never going to convince me, and I hope not many others either.

Maybe its conception. But not its adoption. Its adoption is pretty wide spread wouldn't you say? I say that's because it effectively solved some complex design requirements fairly elegantly.

I don't think its profitable to force what we do into these narrow terms.
And what difference would it make to consider them as tools or machines.
But I think a valid point is missed. Take the automobile for instance. You can take the brakes and use them with one auto or another. Parts are interchangeable. An engine is a complete object consisting of other objects. It has input and output. But, it is an object. Not a function. Its action is a function of those objects' interactions. In this case, I'd like to put my 350 from my Blazer and drop it into my Jeep. A few other objects and viola! I can do it. I liken software to this. The assemblage of parts.
Looking at the human being. The liver is an object. It performs a function. That function is encapsulated. Taking the heart for instance, we've even been able to supplant the human heart with it, and acheive the desired functioning irrespective of the host object. Human or pig.
Procedurally this can't happen. Only with objects. In your world maybe the only objects are the concepts of modules and routines and sub-routines.
This statement was never false.

Let's start by saying I don't think procedural solutions should be banned. I've never advocated one over the other. But subscribe to a balance.
How would you procedurally replace a human heart with a pig heart? Easily enough, as that is in fact a procedure. But, is the heart itself a procedure? Can you swap out the pig procedure for the human procedure? Maybe, but its stretching it to make it fit. An object description works better in this case. I would have the heart be an object, and the transplant a procedure.
Really, can you argue against a blend of paradigms? Is procedural absolutely the best for all cases?
This statement was never false.

The Grand Negus wrote: But OOP has it all inside-out, just like many here who strongly resist (but don't understand) what I'm saying. For example, I've said repeatedly that specialized syntaxes can be used within a Plain English program where they are more effective in getting the job done; but the overall framework should be the natural language, not the special one. We write math books in English (the framework) with the formulae (special syntax) inserted in appropriate places, not the other way around.
Math books are talking to humans. You wouldn't use it to solve the problems.
When I'm performing mathematics I prefer mathematical syntax. I break word problems first down to a set of images that break out the problem into mathematical notational concepts then work with the math syntax to solve the problem. I can't solve the problem using English. When I am writing music I rely upon time signatures to dictate the pace and feel, and I depend on notation and the key signature to dictate the notes and range of the melody. I rely upon chordal notation and the circle of fifths to plan progressions. I rely on that same circle to work out complementary tensions to use in chordal movements, say when writing a sax spread for a jazz standard. When I'm performing code construction aimed at talking to a machine, I prefer the C-Style of syntax. The same as with music and math, I would not want to conceive of and develop the solutions in English. But, now we've left the procedural vs object debate we were originally discussing.

I want to draw class diagram inside visual studio 2005 web application. I know that i can add a new item of type "class diagram" to my solution but the .net class diagram is very poor. I can't add multiplicty for my relation. I can't add an association class. I can't make a dependency between two classes. so, can anyone help me to find a better way to draw a good class diagram and to get the generated C# classes from it?
Thank You

Hope im in the right board for the type of questions i am about to ask.
I'm turning into the BLL / DAL 3 tiers architecture and i'm confused a bit.
Just to clear things up
- i'm working on VStudio 2005, .net 2.0
- my DAL implementation would be in an xsd file (typed dataset)
- my BLL will be my own "wrapper" around the DAL
1) What is the relation between a Database Table, a DAL/BLL set, and a set of operations
i.e: Say i have an Order Editing form. I will in this form Delete full orders, by means of an orders list, and i will be able to Edit some order details, as Both the order header (Master table) and the order rows (Child Table).
Now, should i create a DAL containing both Tables or should i work with 2 DAL/BLL objects, one containing my master table, the other containing my details table ?
On my Shipping Form, i need access to both Order Master/Details and Inventory because when i ship some items, my inventory has to decrease. I also need to validate that i have enough inventory to complete the operation... should inventory be part or the same DAL Definition ?
Should i create a new DAL / BLL ?
I'm sure you can see i'm really confused and i will appreciate any pointers to guide me.

I recently read a 3 part article by Imar Spaanjaars on n-tier (basically 3 tier) architecture in C#. Coming from many years of n-tier architecture in Java I found this article a very good read. It covers the basics real well and explains the important decisions.
The article can be found at

Hi Guys, 
Anybody knows the difference between dependency and association.
I think if there is a association then it implies dependency. right ??
Is it possible to find a clear border to separate these two terms ?? 
Any help is appreciated..
Thanks in Advance

You can think of a dependency as being the case where changes to one object results in a change in the other object. An association refers to a family of links.
