kandi X-RAY | SimpleStorage Summary
The more higher API level, the more Google restricted file access on Android storage. Although Storage Access Framework (SAF) is designed to secure user's storage from malicious apps, but this makes us even more difficult in accessing files. Let's take an example where java.io.File has been deprecated in Android 10. Simple Storage ease you in accessing and managing files across API levels. If you want to know more about the background of this library, please read this article: Easy Storage Access Framework in Android with SimpleStorage.

QUESTION
I'm following a blockchain and smart contract course, and the code I'm trying to run doesn't seem to compile, even though it's the exact same one from the course. I can't say much more about the program since I'm a newbie and I'm just trying to follow along, and I can't find out if there's a syntax error or if it's something else. All I can say, is that I'm using an imported smart contract that I coded in the past lesson and it works perfectly fine.
Specific error: contracts/StorageFactory.sol:20:5: ParserError: Expected pragma, import directive or contract/interface/library/struct/enum definition. function sfGet(uint256 _simpleStorageIndex) public view returns (uint256) { ^------^

QUESTION
solidity newbie here. when I try to read the value of the people array. I'm getting an error:
call to SimpleStorage.people errored: Error encoding arguments: Error: invalid BigNumber string (argument="value" value="" code=INVALID_ARGUMENT version=bignumber/5.4.2)
my compiler version is 0.6.6. not sure what's wrong? any suggestions?
...ANSWER
Answered 2021-Nov-18 at 09:40The error happens when you're trying to call the people() function (from Remix IDE) without passing any value.
Since the People[] public people is a public property, it autogenerates a getter function during compilation. But because it's an array, the getter function requires an uint256 param specifying the index of the array that you want to retrieve.
When you pass an empty string, Remix tries to encode it to the BigNumber instance, but this fails. Only when you pass an (existing) index of the array, it works correctly:
If you want to get the whole array in one call, you need to create a separate getter function:

QUESTION
I am trying to deploy my SimpleStorage.sol contract to a ganache local chain by making a transaction using python. It seems to have trouble connecting to the chain.
...ANSWER
Answered 2022-Jan-17 at 18:17Had this issue myself, apparently it's some sort of Ganache CLI error but the simplest fix I could find was to change the network id in Ganache through settings>server to 1337. It restarts the session so you'd then need to change the address and private key variable.
If it's the same tutorial I'm doing, you're likely to come unstuck after this... the code for transaction should be:

I'm pretty new to this programming and maybe need more practice but I've been having problems trying to connect to the Rinkeby testnet and can't seem to see the problem (Windows 10, Powershell) not sure if it's the .env or how I set them up but I'll send the code or the respective files created with screenshots to see I someone could illuminate the problem. Copy pasted the code and some screenshots of the environment variables. Your help is very much appreciated. For some reason the export commands in the .env are seems as they are not executing(Third attachment).

Hey guys I am trying to deploy my project on the rinkeby chain using infura, but I am getting a ValueError Here is my trackback:
...ANSWER
Answered 2021-Nov-28 at 10:14it appears your env variables are not set correctly, and it looks like in this case it's your WEB3_INFURA_PROJECT_ID.
You can fix it by setting the variable in your .env file and adding dotenv: .env to your brownie-config.yaml.
brownie-config.yaml:
dotenv: .env .env:
export WEB3_INFURA_PROJECT_ID=YOUR_PROJECT_ID_HERE Remember to save these files.
Additionally, you should be on at least brownie version v1.14.6. You can find out what version you're on with:
brownie --version

I'm building a text RPG in plain HTML/JavaScript. I've set up local storage using simple storage to make my life easier. That said, I'm running into a funny issue with treasure chests. If you open a chest, the function properly hides the button to prevent opening the chest again. But if you reload the page after saving, the chest re-appears! The class that was added to the chest is removed, allowing the player to pull from it again. Since their inventory properly saves they could in theory get infinite potions.
HTML:
...ANSWER
Answered 2022-Feb-15 at 21:01I figured it out thanks to some of the hints from Heretic Monkey and Cbroe.
I solved the issue by pushing the id string of each opened chest into an array called "opened". When you save, the array is saved. When you load, opened is reloaded. Then the load function calls the applyOpened function, which then applies a .map to the array. It takes each id and places it into a document.getElementById, then adding the hidden attribute to it. This is done ahead of loading the page for the player, preventing them from accessing the element without using the console (and that would be cheating!). Again, simple storage makes it so I don't need to convert the array to a string, but it should work with regular local storage as well!
