Oh, to bad. I have looked as some videos and in some ways it is easy to understand but then again not :) Thanks anyway! Edit: I saw the link in the email I got from the post so I see the video there. Thank you!

Ok, thanks!

Ok, I see. Thanks! By the way, do you know of any good MVC 5 tutorial? I have tried some but they seem to get to comlicated to fast.

Ok, thanks! Kind of what I guessed. Still a bit confusing that you can start a project as Web API I think. Feels like you should start MVC and then Add Web API. But I think I have to read more about it.

ASP.NET has become increasingly complex. Webforms was the old but still valid technique. MVC means you can stucture your application better and have more controll. So is Web api a third technique or should I use it to create webservices and other things. So my questions is: Is Web Api a third technique to be used instead of webforms and MVC?

Hm, so when do you use this? Feels like everything I thought my students about private variables and getters and setters is obsolete... Here´s something to put in my signature. The more I learn the more I realize how little I know...

I will absolutely!

Well, as said, I realized that it was in your signature and again, I apologize humbly. Yes, I been a teacher for C# beginners but have alot to learn myself obviously :)

As I said I misunderstood. It was the signature, not aimed at me. Yes, he did answer my question and thanks for the further clarification.

Oh, really sorry! Realize now that it was in your signature. again, I apologize.

I think adding the "Seriously, do it" was unnecessary, like I was some idiot. You could have only said "please read this" or something.

Read this. Seriously, do it. "If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome" "Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid"

Saw this in an example when setting properties. Is this some kind of special ASP.NET MVC syntax?

var movie = new Movie() {
Name = "Shrek!"
};

Where Name is a property of the class Movie.

I added a sitemap and then chose that as a source. Then I get this:

Configuration Error

Parser Error Message: Host 'fe80::ad93:da36:44e1:3cca%11' is not allowed to connect to this MySQL server

Source Error:

I never chose MySQL, what is going on?

I meant upvote, sorry. For my other question I think I shown all code, but can post if again of course. Anyway I think I found a solution. Added this: repaint(); revalidate(); Seem to work. Not sure if the order matters.

I meant how can I upgrade your answer to give you credit :) Sure I can start a new question if you want. All I do though is call the class I shown in main like this: new MainFrame(); And then I inherit from the main window like: public class MainFrame extends JFrame implements ActionListener { So most code is in the constructor. So should I post a new question?

Well, are very greatful. Don't really know how to upgrade, could you tell me? Also, I have another question and hope it is ok to ask it here. When I start the window it is blank or only a few items. When I minimize the window and maximaze it again, everything is fine. Do you know why this is?

Ah, of course! Thank you, so simple :) So, again, thank you very much! So can I mark as solved or give you credit?

Ok, I'll try again. This is my total code in a class that inherits from JFrame instantiated from main(). Slightly changed because I come from Sweden. So I enter the info in the textfield for title, author and price. If I enter the info for one book and then press "show books" it works. I enter another book and press show books again it still works. The textarea shows all books. If I enter a book and doesn't press "show books", enter a few others and then hit "show books" it only shows the last entered book. If I have entered a few books using the first method (enter book, press "show books", enter another book, press show books again)and then quits using the Close-button one books is saved, not more.

Thanks for your reply. Could you show me some code? I tested to add some objects by writing in the textfields and pressing the button (btn). If I do this for some books and then hit the second button (btn2) it only shows the first book in the list. If I add a book and then hits the second button it show that book. If I add a second book and hits the second button again, it shows both books.
