you can try this

It seems like the copy has logically finished, but hasn't been fully written to the physical USB flash drive. That is to say, your OS has cached some of the data from the copy, and will actually write it to the drive at a later time, but definitely before the drive is unmounted.

To check if this is the case, you can check (either within Python or through some other program) if the copy has completed once the code has moved on past shutil.copytree. If it has, then the issue is almost certainly that the USB flash drive was not safely ejected.

You should be able to solve this by unmounting (i.e. safely ejecting) the USB flash drive before removing it.

You have to provide both annotations as object in 1 array, not an array containing objects containing arrays, see example:

Instead of adding them in some variable save them inside array . So , in below code i have added function call addAttributes whenever your sno is checked . Then , as we are not having docCodes there you can loop through checked checkboxes inside dialog and then push them inside array .

Demo Code :

For c# Ticks:

The value of this property represents the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight, January 1, 0001 in the Gregorian calendar

For Javascript Date:

JavaScript Date objects represent a single moment in time in a platform-independent format. Date objects contain a Number that represents milliseconds since 1 January 1970 UTC.

In C# to get the number of milliseconds since some point in time (eg 1/1/1970) you could use:

There appear to be two key issues:

Enter/Update/Exit

The exit selection only contains elements when there are selected elements in the DOM which do not have corresponding items in the data array. In your case we have an empty selection with bound data:

Collision detection depends on your needs.

• Bounding boxes are simple and can detect if the x, y edges of each object are not within one another. This is fine for fast moving games and things where you don't necessarily require point precision.
• Distance vectors are also simple and perfect solution for circle collisions. They calculate the difference in distance between two objects according to a radius prescribed with the hypotenuse of distX^2 + distY^2.
• Compound bounding objects are harder to calculate, especially for concave areas on objects of arbitrary shape. There are too many notable and novel approaches to collision detection beyond these to remark on here.

They're also increasingly complex depending on things like variability (if they're deformable objects, if they have particle seams, etc and 2d vs 3d object collision can be vastly different worlds as well. There are tons of articles, but I'll post one with implementation here

You have to calculate the movement per frame depending on the frame rate.

pygame.time.Clock.tick returns the number of milliseconds since the last call. When you call it in the application loop, this is the number of milliseconds that have passed since the last frame. When you call it without a parameter (framerate=0), the FPS are unlimited.

Define the distance in pixels that the player should move per second (move_per_second). Then compute the distance per frame in the application loop:

It's playing indefinetely, because once it's visible - on each render loop you call playSound().

If you add a simple toggle check - You'll get your "once per visible" result:
