Up or Down ?
I'm a very visual person. I'm thinking of my application as a hierarchy, where the top is the root and the bottom is a leaf.
I'm also under the understanding that IoC containers are ignorant of their contained objects' responsibilities/functions...

If you are using a container, you are likely familiar with Dependency Injection and Inversion.

I've recently had to update a relatively large control library that uses Ninject 1.0 to Ninject 2.0 to help resolve some issues I had with 1.0. The update has gone well and I think Ninject 2.0 is a lot quicker.
However to try and avoid this problem in...

In my case, I have a base class that calls StructureMap.BuildUp(this), and the user control would have properties like:
public IBlogService _blogService{get;set;} public IEmailService _emailService... .
Support property injection, and inject dependencies to "this".

Can anyone explain exactly how the Strategy Pattern relates to Inversion of Control?

Answer Snippets (Read the full thread at stackoverflow):
If the implementor, on the other hand, gets the algorithm to use from some other source .
If the developer, then that is inversion.
On its own, the pattern does not introduce inversion of control.
From outside.

The way this is most commonly achieved....
The idea is that instead of two pieces of code relying on each .
It basically says:
High level modules inversion is to make reusable software.

Inversion of Control (or IoC) can be quite confusing when it is first encountered. What is it? What problems does it solve? When is it appropriate and when not?

Inversion method and only changing a small piece of the code....
To me, inversion of control is turning your sequentially written code libraries what events you're interested in, and it will let you know when they happen.

I've been seeing a lot of references Dependency Injection (DI) & Inversion of Control (IOC), but I don't really know if there is a difference between them.
I would like to start using one or both of them, but I'm a little confused as to how they are different...

DI is a form of IoC, I gave a pretty->get requested dependencies from module .
They are inherently linked.
Inversion of Control usually refers to the "containers" while Dependency Injection refers called Inversion of Control.

I'm trying to inverse a matrix with version Boost boost_1_37_0 and MTL mtl4-alpha-1-r6418. I can't seem to locate the matrix inversion code. I've googled for examples and they seem to reference lu.h that seems to be missing in the above release(s). Any...

And yeah, like you said, it looks like their documentations says you need lu.h, somehow:
How do I invert... .
From the documentation.
I don't remember what you have to do with the pivots, though .
Looks like you use lu_factor , and then lu_inverse .

I'd say the worst abstraction inversion I've seen is using.

What is a proxy object in the Inversion of Control / Aspect-Oriented sense?
Any good articles on what a proxy object is ?
Why you would want to use one ?
And how to write one in C# ?

Charles Bretana's.
That refers to a common pattern where dependant with inversion of control because I resolve interfaced types only with my IoC.
As to Inversion of Control (IOC)..
The call is done.

For those of you who aren't familiar with the concept, abstraction inversion is the implementation of low-level constructs on top of high-level constructs, and is generally considered a bad thing because it adds both needless complexity and needless overhead...

Can suffer from abstraction inversion however, because the internal implementations are often hidden.
