QUESTION
I wanted to make a circle cursor and I copied the code from codepen
I am working in another IDE called Repl.it and so I copied the exact same code from codepen to repl.it (Note: I did use the correct code from codepen by compiling it first)
The code is not working in repl.it
I am not sure what I am missing, but I am pretty sure it has to do with the tags. Any help would be much appreciated.
My Output:
The cursor stays at the top left and does not move at all for some reason

When creating the NavHostFragment using FragmentContainerView or if manually adding the NavHostFragment to your activity via a FragmentTransaction, attempting to retrieve the NavController in onCreate() of an Activity via Navigation.findNavController(Activity, @IdRes int) will fail. You should retrieve the NavController directly from the NavHostFragment instead.
Looks like you should use

Answered 2021-Jun-09 at 20:19The page is rather well organized so scraping it should be pretty straight forward. All you need to do is get the plugin card and then simply extract the necessary parts.
Here's my take on it.

QUESTION
we are using a STM32H743VIT6 on a custom board with a JLink debugger. Out of the blue the processor jumps in a state where it isn't possible to flash the ECU anymore. The board is running but nether JMem nor our IDE (uVision) are able to access or detect the controller. Has anyone else encountered this behaviour so far? Google wasn't helpful either.
...ANSWER
Answered 2021-May-30 at 19:21It is almost impossible to archive unless you enable RDP (which is very hard to archive if it was not the intention of the programmer).
You probably have screw-up the board design. You should have pull-up resistors on the debug lines and NRST connected to the programmer.
If you do not have NRST available simple solder the wire to the NRST, and when the programming probe connects to the uC, connect it to the GND.
If the NRST line is connected to the programmer you need to select nn the configuration "Connect under Reset"
QUESTION
I am really newbie in Flutter and SQLite. I need to store some data got from a DB into a global variable (in this code it's a local variable just for exemplification) and I don't know:
- where is the best point I can do it (now I put it in the homepage's initState method);
- how I can store future data in a no-future variable.
Below is the method for the data extraction
...ANSWER
Answered 2021-Jun-14 at 03:46Reading from database is an asynchronous activity, which means the query doesn't return some data immediately. so you have to wait for the operation to complete and then assign it to a variable.
QUESTION
I have this code I have entered into Remix IDE, as ReceivedEther.sol, a standalone smart contract.
I've transferred 0.02 Ether to the smart contract, using MetaMask.
When I checked the smart contract's balance, it returns 200000000000000000, as expected.
If I try to use the transferEther function, however, and enter a number smaller than this - say, 0.005 ETH, or 50000000000000000 as the amount - it doesn't work using MetaMask.
When MetaMask prompts me it's never for that amount. It's for 0 ETH and 0.00322 gas fee (or whatever the gas is). Basically it always set the amount of ETH at 0 and only charges the fee.
Why can't I transfer an amount of ETH using this function in the Remix IDE with MetaMask?
...ANSWER
Answered 2021-Jun-13 at 21:44Your code sends ETH (stated in the _amount
variable) from the smart contract to the _recipient
. So it doesn't require any ETH to be sent in order to execute the transferEther()
function.
If you want your contract to accept ETH, the function that accepts it (or the general fallback()
or receive()
function) needs to be marked as payable
.
