kandi X-RAY | BasicContract Summary

BasicContract is a C++ library typically used in Blockchain, Ethereum applications. BasicContract has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The basic standard API for tokens, on EOSio networks, does not allow practical implementations of non-custodian peer-to-peer applications. The following smart contract, closely inspired by the ERC-20 Ethereum standard, allows users to preapprove other accounts (or smart contracts) to spend a designated amount of funds in their name. To do so, we have implemented two new actions that are added to the standard eosio.token contract:.

"truffle init" creates files with read only permissions

Is it possible to use variables with the 'DIALOG' and 'CONVERSATION' commands?

Getting mined blocks instead of the supposed returned values

QUESTION

"truffle init" creates files with read only permissions

Asked 2021-Apr-10 at 09:45

I'm wondering if this was intentional that truffle creates all its folders and files as read-only. Every time I use truffle to generate files, I have to manually change the permissions with chmod so that I can write to them.

Is this an issue with how I installed truffle globally and with sudo?

Example of a file's permissions that I just created with truffle create contract

Solution: Run the truffle command under regular user, not using sudo.

QUESTION

Is it possible to use variables with the 'DIALOG' and 'CONVERSATION' commands?

Asked 2020-Jun-23 at 13:57

I've been able to setup my Visual Studio (2019) Database Project up and using database references fine for tables, stored procedures, views, etc. They all seem to match up fine with the schema I've imported. However, I can't seem to avoid errors when it comes to referencing the same database's contracts, types, services, etc. When I reference the target database's service I have no issue (I assume this is because it accepts basic NVARCHAR strings versus a strongly-typed schema.

I've got the following example that just sends a message to another database's service. I get the error: "SQL71502: Procedure: [dbo].[z_Queue_SendMessage] has an unresolved reference to object [@VariableName]" with @VariableName being all of the following: (@RequestMessageType, @BasicContract, @InitiatorService)

QUESTION

Getting mined blocks instead of the supposed returned values

Asked 2019-Apr-25 at 13:20

I've just deployed a Smart Contract using the ethereum wallet. I got the Smart Contract address , I copied its ABI from remix and verified it on ethereum wallet,it was active and I could see all its methods.

Then I tried to call it from my nodejs server.I did it,I didn't get any error... But instead of a classic response like the returned values of the methods below I got mined blocks....and this is very weird I think... How am I supposed to get the methods output(the returns) ?

After that I tried to deploy another contract,this time a very simple one with the same methods name,smart contract name,parameters but without code inside the methods only a basic hard-coded return.When I deployed this contract as well I got the same mined smart contract address...which is weird,in my opinion...

I've been using 1.0.0-beta.46 , nodejs , expressjs When I said eth wallet I meant...that website generated with puppeth , on /#wallet page

Here is the basic smart contract I tried to deploy second time.The result was the same as the first smart contract.

pragma solidity >= 0.4.22 < 0.6.0;

contract BasicContract {

There are two ways to invoke a function in a smart contract: through a transaction sent to the network or via a local call.

Transactions don't have return values. What you get back from the library you use to make the transaction is typically the transaction hash. Any return value from the function you invoked is discarded.

A local call doesn't involve a transaction to the network and thus can't change any state. But it does give you a return value.

Which method is chosen by default for most libraries is based on whether the function is state-changing or not. If you mark your functions as view or pure, it tells the library that those functions don't change state and can then safely be just called locally to get a return value. So a simple "fix" for the above code is to make those functions pure. For functions that do change state, you'll want to switch from using return values to emitting events instead, which can be read after the transaction is mined.
