I am almost done with an exercise but need help with the last bit. The premise is to have only a clicked article to be shown out of a list of four articles. I can hide all but the first article and get the heading to show when the respective article is clicked but I'm having trouble with the code to get the actual article to show. Here is an HTML snippet (let me know if you need more):

Is there any way to limit the results returned by the Google Books API?

For example the following URL:

https://www.googleapis.com/books/v1/volumes?q=isbn:0751538310

I am converting an existing application to consume JSON via POST from Bandwidth's V2 SDK for .NET. I'm not well-versed in either C# or JSON.

The previous version simply sent a JSON string like so:

So, I'm coding out a hangman style game as is the custom when learning how to user JS. I have it working pretty well, but I cannot seem to figure out how to properly identify and prevent duplicate wrong guesses. Example: if you press "f" and it is not in the word, display and decrement the remaining scores once, and if you press "f" again, ignore the input. Here is my code thus far. I have my existing code in the function but it doesn't currently do anything. Any advice is appreciated.

So I was experimenting with javaFX a bit since it is a part of one of my subjects. I have a catapult that shoots a ball in certain direction. I was wondering if you could somehow change the color of a canvas background in a runtime on a certain occasion - when a ball hits the wall for example. I already figured out how to make the ball bounce of the wall, but I cannot figure out how to change the bg color in runtime.

I'm using import javafx.scene.canvas.GraphicsContext; as it is what we kinda "have" to work with.

I thought something like this would work, I found some threads about sleep so I gave it a try.

I have two boxes sitting on a rectangle that I want to balance on a 2D rectangle that acts like a see-saw.

The onTouchEvent method always says that the event is 0 (MotionEvent.ACTION_DOWN) once I touch the screen for the first time. I don't know how to get it to report when I stop touching the screen.

The stage variable tells it what tap number it is on in the three part process (start, stop, and release)(made for a catapult like game)

public static int stage = 0;

I have a Stream Listener as

I have been refactoring some of our clunky and not working LINQ queries lately when I find issues in our project. Here is one that is throwing me for a loop. I must confess, I am an android developer catapulted into C# with entity framework so I don't truly understand what is happening here. Nevertheless these queries look nearly the same to me (sprinkle a subquery here and a new join there). The first method will return without error:
