Hi Bryan,

Here is how I understand it.

MVP
In MVP the presenter communicates with the model and with the view, AND the
model and view can communicate.  An example.  The presenter tells the view
to load a list based upon some ID.  The view can then query the model to
return the data (maybe a dataset) for a given ID.

MVC
In MVC the model and the view never communicate with each other.  For the
above example, the presenter would query the model for the data for a given
ID and then tell the view to display the dataset.

Basically, the MVP pattern allows the view and model to communicate and the
MVC pattern does not.  I just implemented my first MVC patterned program
using CAB at work a couple of months ago.  I really like the MVC pattern
over the MVP pattern as it is clearer to me.  I like it enough to use being
using it now to implement a side project that I am currently working on.

I know this is probably clear as mud, but I am knew to this stuff.

Thanks,
Bobby

Does anyone have a short (and good) explanation of MVC coding?

I've read several articles on it and it still doesn't make any sense to me.

I know Ruby0on-Rails projects use MVC and so do several PHP
frameworks, but I'm still at a loss of the difference between the
Model and Controller.

I get the view portion, that's the UI parts.

Help. Please?
