Live Share Whiteboard enhances the existing Visual Studio Live Share experience, by enabling you to open an integrated whiteboard, without needing to use a seperate tool or service. All participants within a Live Share session can collaboratively draw on the whiteboard, and see each others changes in real-time. For certain use cases (e.g. technical interviews, mentoring/classrooms), this can provide a useful means of communication, in addition to an audio call and co-editing and debugging. This is an experimental extension, and isn't meant to replace existing solutions for creating persistent diagrams. For example, you can already use the PlantUML extension today, and synchronize the contents in real-time over Live Share (since it's just a text file + a preview surface). Therefore, the whiteboard is useful for creating ad-hoc/ephemeral drawings/diagrams, that would otherwise be inefficient to create via other means (e.g. UML).

QUESTION
I am making a whiteboard (blackboard), to move cubes as counting blocks, or logic cubes, and connect them with lines to make a connect the cube logic board.
I have an initial cube, and the button in the bottom left corner expands three more cubes, but when I try to remove the expanded cubes after adding a class to the expanded cubes,('addingAndSubtractingCubes'), all three cubes are not removed from the program.
In the for loop where im cycling through the NodeList the middle cube is being skipped it seems like at allCubesAdded[i].remove() where i==1;

QUESTION
I am trying to create a relatively simple classroom-like site with overlaying images. Basically, there are a bunch of pictures you can interact with that will take you to different websites with different resources. I am struggling immensely with getting the sizing and proportions of all the images correct. I want there to be a background image that stretches to span the entire page and then carefully placed images/text over the background image/other images. As you can tell, when resizing the JSFiddle, everything gets disproportionate.
A more concrete example of what I'm trying to do: You can see the text over the "chalkboard" image. I want it to appear as if the text is writing on the chalkboard so it shouldn't be moving off the blackboard when resizing the window or looking at it through different aspect ratios. I'm trying to do this with lots and lots of images so a thorough explanation would be most helpful.
...ANSWER
Answered 2022-Mar-18 at 04:54As you already have the positioning done in terms of % of the actual picture I think all you basically need to do is make sure that that picture's container maintains the same aspect ratio whatever the viewport aspect ratio is.
I did a rough look at your webp image and converted it to a png and took the dimensions - you will probably want to refine that to be more accurate.
Here is the snippet:
QUESTION
I'm trying to switch from python to c for sometime, I was just checking out a few functions, what caught my attention is sizeof operator which returns the size of object in bytes. I created an array of strings, and would want to find the size of the array. I know that it can be done by sizeof(array)/sizeof(array[0]). However, I find this a bit confusing.
I expect that large array would be 2D (which is just 1D array represented differently) and each character array within this large array would occupy as many bytes as the maximum size of character array within this large array. Example below
...ANSWER
Answered 2022-Feb-26 at 19:08It's happening because sizeof(words[27]) is giving the size of a pointer and words[27] is a pointer, and pointers have a fixed size of each machine, mostly 8 bytes on a x86_64 architecture CPU. Also, words is an array of pointers.
each of the character arrays occupy 8 bytes, including the character array "optimization".
No, each word in words is occupying a fixed memory (their length), 8 bytes is the size of pointer which is unsigned long int, it stores the address of the word in words.
QUESTION
I m really sorry if this question is answered a thousand times before, I m really new to React, and don't know how to describe what I want to say in correct words to search for it.
I have a canvas component (A simple HTML canvas and I am using fabric.js on top of it) and a sidebar component (Which contains quite a few buttons such as a button to change line thickness, line color etc). Now what I want is when I click on the button in the sidebar (say, change line color button), it will call a function in canvas component or anywhere else, that sets the color property to be used for canvas drawing.
IMPORTANT: After a bit of googling what I found is that React encourages self-containment, all logic for a component should be inside it. But I am trying to make a whiteboard app. There are different toolbox, menu, sidebar components - all of which affect my canvas. I was writing the code for it in plain HTML, CSS, JavaScript. But I soon realized that my code was getting too difficult to read and modify. This is where I searched for something that lets me break my HTML code into pieces for easy management - such as one HTML code for toolbox, another one for the sidebar etc. And React and similar frameworks appeared. React does the job I originally searched for - breaking my code into components. But I am not getting how to do the following in React:

Answered 2022-Feb-25 at 20:38The parent component can contain the methods you want, and pass the function to the child component.

QUESTION
I have been assigned with creating a simple Python project of my choice and as for now I am working on a little Tkinter GUI app. Having successfully written the part of the code responsible for multiple Drop-Down Menus, I wonder how to use combination of users' chosen options for creating commands opening the designated window. Is there any neat way to do it ? Would it be enough to somehow define the combination of choices in the function, which constructs button command ? Thank a lot for any piece of advice on this.
...ANSWER
Answered 2022-Jan-21 at 20:48A "neat" and orderly way to do it in Python would be to map each combination of choices to the desired window-opening function via a dictionary. Looking up the function to call would simply be a matter of combining the current choices together to form a dictionary key, then using that to look-up the corresponding function to call.
Below is a runnable example of doing that:

I have a online whiteboard that Safari users cannot connect to. They get the following from the console.
Refused to connect to wss://whiteboard.[MYDOMAIN].com/[MOREPATHSTUFF] because it does not appear in the connect-src directive of the Content Security Policy.

Answered 2021-Aug-11 at 23:34CSP has some unintuitive traits. One is:
Websockets like wss://example.com are not captured by wildcards such as *.example.com or even *
In order to allow the websockets - you need to explicitly add them with wss://example.com or even ws: wss:
If you only want to allow anything on the connect-src, then adding
connect-src * ws: wss:; to your policy should work (as you mentioned).
QUESTION
I have created a HTML5 canvas whiteboard which can be used to write anything using mouse.I had tried to add the eraser functionality to the whiteboard which will erase pixels from the screen, but it is not working. I am sharing the relevant portions of code
...ANSWER
Answered 2021-Dec-20 at 16:07Try using a brush the same color as the background color of the canvas. It will look like erasing, but it's like putting white-out on white paper.
sugs on your code:
use let instead of var
for onPaint, do function onPaint() {...}
instead.
QUESTION
I am working on a simple whiteboard application where the drawings are represented by quadratic Bezier curves (using the JavaScript's CanvasPath.quadraticCurveTo function). I am trying to implement functionality so that an eraser tool or a selection tool are able to determine if they are touching a drawing.
To show what I'm talking about, in the following image is a red drawing and I need to be able to determine that the black rectangles and black point overlap with the area of the drawing. For debugging purposes I have added blue circles which are control points of the curve and the green line which is the same Bezier curve but with a much smaller width.
I have included my code which generates the Bezier curve:

And if it doesn't work maybe you can take a look at this library: https://pomax.github.io/bezierjs/
As suggested by Pomax in the comments the thing you're looking for is in the library and it looks like there is a proper explanation.
There is a live demo if you want to try it: https://pomax.github.io/bezierinfo/#projections
The source code of it is here: https://pomax.github.io/bezierinfo/chapters/projections/project.js
To use it install it using the steps from GitHub: https://github.com/Pomax/bezierjs

ANSWER
Answered 2021-Oct-25 at 21:08Maximum Recursion Depth Exceeded means that your code has called itself too many times for the interpreter to process. In this case, I believe that the culprit is self.updatedcollisions() in your second else statement.
Let's say that you called updatedcollisions() in your code. If confirmationscreen is false, then it jumps to the first else block. In that else block, if this object is not in the correct bounds (the if and elif statements are both false), the code jumps to the final else block. Within the final else block, updatedcollisions() is called again, and the cycle repeats over and over until the recursion is too deep to process, crashing the program.
QUESTION
I followed this guide to set up swiper slider in my Angular 8 application.
I get the below error when importing NgxUsefulSwiperModule into app.module.ts
ERROR in ./node_modules/ngx-useful-swiper/fesm2015/ngx-useful-swiper.js Module not found: Error: Can't resolve 'swiper/bundle' in 'C:\Users\Dan\NewAngular\node_modules\ngx-useful-swiper\fesm2015'
I tried deleting the node_modules folder and reinstalling everything but it fails every time.
Can someone please tell me what I'm doing wrong?
This is my package.json file
...ANSWER
Answered 2021-Oct-14 at 06:37Looks like ngx-useful-swiper is not compatible with the latest version of swiper.
The error clearly states that ngx-useful-swiper is trying to access a file that's not available in the swiper package you just installed.
Try installing a different version of swiper slider.
Follow these steps:
1) Uninstall the current swiper
