can anyone help me provide a hint on how to obtain orders from the ebay Sell/Order API ( not the xml, the REST-API)
the most obvious question is: which node is the right one? Buy/orders API (https://developer.ebay.com/api-docs/buy/order/static/overview.html) in my opinion isn't the right because:
i (the user of the endproduct) am the owner of the ebay account
i dont want to buy something i want to see what anyone else have bought from me (the items i sell on ebay)
i only want to see the orders which are unpaid (buyer hasn't payed yet) or which are not send to the buyer but the buyer has already payed.
from my understanding this API (REST-API buy/order) is only for someone who wants to build an App in which you can buy something from ebay directly. Correct me if i am wrong.
If my understandings are right then which REST-API from ebay would be the best / most feasable to use?
i quite literally lose track on which Ebay API Node does what - the eBay-"Support"-Team "helped" by sending me an "please rate us"-Mail instead of answering the questions i asked- not quite useful, so i kindly ask the gods of stackoverflow or maybe Mr. Chilkat Software himself if i am lucky?
Next Step, if someone could help would be how to use them with the Chilkat Software ActiveX Library? I would love to use this Library because he's providing a ton of good examples which are working flawlessly and without any doubts or misleadings.
Also the library is working in VB6/VBA which is the target to implement it.

I know, its a pain in the butt but there is no real alternative for the task i need to resolve and there's only a little piece of the puzzle left missing to paint the great picture complete.
I would love to hear from you and get help in my task/journey.
Thanks in advance
I apologize in advance if my question is vague and / or not constructed well. I am just getting started exploring ASP.NET Core MVC and Razor Pages (MVVM) and I am confused as to what is the difference between a model and a service. What questions should I ask myself before deciding if I need a new model or a new service. Any help would be greatly appreciated.
I am answering my own question because after posting this question I found a great explanation of what the differences are between a model and a service by reading the MVC Basics chapter in this great book - https://nbarbettini.gitbooks.io/little-asp-net-core-book/content/chapters/mvc-basics/
When I look at MVC diagrams I have this objection: why Controller is pictured facing user and View is hidden somewhere behind?
In my opinion user sees and interacts with View (this is what he sees in browser) and via View user "talks" to Controller, so why Controller is first in line?
Also, shouldn't diagram be shown like tower structure (instead of triangle):
View -allows user talking to- Controller - to- Model (on the bottom) - then (feed)back to- Controller -adjustment made to- View
When I see diagram with Controller facing user, I always have this strange picture of user, with a MVC diagram in one hand and screwdriver in another, popping computer's box open and looking for a Controller to get MVC started.
It's really unfortunate that most articles and books still use such useless diagrams to represent MVC. A more useful diagram for MVC is actually a UML sequence diagram like Dino Esposito uses on his book Microsoft .NET: Architecting Applications for the Enterprise
Secondly, as you point out, most MVC articles and books have not been updated to describe how MVC is applied nowadays in web applications and still talk about MVC as it was originally envisioned 20+ years ago.
The Esposito book that I mentioned has a really good chapter about this where he describes how MVC (as originally described) is dead and we should now be focusing in modern variations of it like Model2, Passive View, and Supervising Controller. I've got a review of this chapter on my blog that you might find useful.
i developed a lawyer website and looking the below mentioned:
I have 5 categories and each category have 40 questions(in 4 pages with/without mandatory options).all the questions are managed by admin only and the questions have checkbox,dropdown,radio button and so on.

Each category have different 40 questions.
please help me.am new to joomla.
Thanks in advance.
EDIT:
Multi-Form Submit with progressbar component for free.please recommend this.
I'm using ChronoForms 4 for simple questionnaire and it's very powerful, as not so user-friedly in admin configuration. The best feature is that you can customize every action on form showing and on form submitting. However I thik it's a bit hard to create a multipage form with this, but maybe in the forum some may answer, they reply very quicly.
I’m about to write quite a big web site that will basically be a forum, divided to (many) different subjects and allow users’ score.
I’ll be using MVC, so I (“naively”) asked this question about how to partition the Model portion of MVC, which is likely to be very large.
Two things I realized from the answers I got:
I really don’t know much about designing software.
There are many ways to implement MVC
So I have now two questions:
(That’s a bit theoretical-) Would
you say designing a software is
completely deterministic i.e.- For a
specific set of requirements there
is one best design? If not- why?
What are the common components
(necessary and optional) of MVC that
I should consider in writing my site
(resources for beginners would be
great)?
Although Java/JSP/Servlet targeted, you may get some useful insights out of this answer. It describes the common patterns to be used in MVC and the approach how to fit them all together. Here's a summary:
Front Controller pattern (Mediator pattern) - the controller
Strategy pattern - the business actions
Abstract factory pattern - to let controller obtain the desired business action.
Facade pattern - to abstract the raw HTTP details away.
State pattern - to introduce a lifecycle which abstracts gathering of request parameters, validation, conversion, updating model values, etc away.
Composite pattern - to create an advanced component tree for the view.
For ASP.Net MVC, a good entry level, free tutorial is the 'MVC 2 Music Store' by Jon Galloway. You can find it here. Note that the current version of ASP.Net MVC is MVC 2.
A more thorough tutorial is the Nerd Dinner tutorial. However the creators are still in the process of updating it to MVC 2. You can check for updates and downloads here.
I would recommend using resources for MVC 2 as there are some significant improvements over the first version. Also MVC 3 is on the horizon and you want to hit the ground running.
I would also recommend keeping an eye on MVC 3 improvements if you're serious about getting up to speed in this space. A good blog to subscribe to is Phil Haack's Haacked. Phil is the project manager for MVC at Microsoft.
In terms of textbooks, the gold standard is Steven Sanderson's 'Pro ASP.Net MVC 2 Framework'. The first review on Amazon is from Scott Guthrie, a Microsoft VP, who raves about the book. He also has a competing book of his own. You can get the ebook from Apress here. Do a google search for Apress promo codes and you may save a few dollars.
Good luck.
Software is definitely not deterministic. Theories in programming are constantly developing and improving, which is what makes the field such a fast-paced and exciting place to work. Also, what may seem like the best approach to a software problem right now could be obsolete in a matter of months by a newer, improved technology.
