Neo.Lux already supports sending assets to multiple outputs in a single transaction, however the Light Wallet demo is missing support for this in the GUI.

NeoRPC.cs row 58
public override byte[] GetStorage(string scriptHash, byte[] key)
{
var response = QueryRPC("getstorage", new object[] { key.ByteToHex() });
var result = response.GetString("result");
if (string.IsNullOrEmpty(result))
{
return null;
}
return result.HexToBytes();
}
you missed the param of "scriptHash", it should be the first param in new object[]

Thanks for your work.
There are some obvious errors in file "NeoDemo.cs".
eg:
using NeoLux; using Neo; using Neo.Cryptography; using Neo.VM;

Base on your lastest Neo-Lux it should like
using Neo; using Neo.Lux; using Neo.Lux.Core; using Neo.Lux.Utils; using Neo.Lux.Cryptography;

It will be greatly helpfull if you can fix them .
Thanks in advance

Some users might need to test their dApps in a private test net, Neo-Lux must have a way to support this.

I can see from source code that .NET Core standard is added, but I guess it isn't published to nuget.

Are you planning to publish it ?

Should be possible to call a method Withdraw(from_address, to_address) which will create a transaction that requests an asset withdrawal or token withdrawal.

Hi guys .
Please tell me when your library is coming to .net ?

https://github.com/neo-project/neo/blob/b9bb68b94e9231f9533ebbed2ca98ffbda0b938a/neo/Network/RPC/RpcServer.cs#L200:

                case "getvalidators":
                    {
                        var validators = Blockchain.Default.GetValidators();
                        return Blockchain.Default.GetEnrollments().Select(p =>
                        {
                            JObject validator = new JObject();
                            validator["publickey"] = p.PublicKey.ToString();
                            validator["votes"] = p.Votes.ToString();
                            validator["active"] = validators.Contains(p.PublicKey);
                            return validator;
                        }).ToArray();
                    }

Thanks for your wonderful work

It's realy helpful on working with unity.
I want to get a datanode object on calling a method from contract.
but now I got a transaction from which nothing usedfull data is included.

Any advice is appreciated.

The logic in WaitForTransaction was wrong for finding the confirmed block that contained a specific Tx. I've fixed it.
I found this by running my console app side by side with the NEO-GUI transaction log.

CallContract would only succeed after the previous Tx was confirmed in NEO-GUI and WaitForTransaction was returning too quickly ...relative to what I was seeing in NEO-GUI.

Wait times are about 40-50 seconds (FYI).

Fixes:

https://github.com/mwherman2000/neo-lux/blob/master/Neo.Lux/Core/NeoAPI.cs#L1069

The fix uses a derivative of my "batches of blocks" looping pattern that I first used in the NeoEventMonitor1 class: https://github.com/mwherman2000/neo-lux/blob/master/NEO.mwherman2000.MonitorEvents/NeoEventMonitor1.cs#L81

Hi all,

I would like to add MyWish (http://neoscan.mywish.io) to NeoRPC.cs file as PrivateNet.

I have added the following lines, but it does not work.

Could you help me about how to add MyWish as RemoteRPCNode?

Thank you.

public static NeoRPC ForPrivateNet()
        {
            return new RemoteRPCNode(20332, "http://neo.mywish.io", NEONodesKind.MYWISH);
        }

Also, I have added this code structure to NeoRPC.cs file.

 case NEONodesKind.MYWISH:
                    {
                        nodes = new string[4];
                        for (int i = 0; i < nodes.Length; i++)
                        {
                            nodes[i] = $"http://neo.mywish.io:{port}";
                            port = port + 1;
                        }
                        break;
                    }

I'm playing around with neo-lux tonight. Trying to call my NPCdApp:

Script Hash: 0x7074acf3f06dd3f456e11053ebf61c5b04b07ebc (testnet)

public static object Main(string operation, params object[] args) (link to source)

win-gui parameter type: 0710

I tried to change your Demo.cs in a simple way but I'm just getting a null result back (should get back the string "success"). Here's the 4 lines I added to your Demo.cs:

https://github.com/mwherman2000/neo-lux/blob/master/neo-lux-demo/Demo.cs#L51

var NPCdAppContractHash = "0x7074acf3f06dd3f456e11053ebf61c5b04b07ebc".Replace("0x", "");
var response2 = api.TestInvokeScript(NPCdAppContractHash, "test2", new object[] { new BigInteger(5) } );
var result2 = System.Text.Encoding.ASCII.GetString((byte[])response2.result);
Console.WriteLine("result2" + result2);

Is there a simple fix?

Here's the Main() for my SC: https://github.com/mwherman2000/neo-persistibleclasses/blob/master/NPCdApp/NPCdApp.cs#L96

Cheers,
Michael

How to use api.CallContract?

public Transaction CallContract (KeyPair key, UInt160 scriptHash, string operation, object[] args, string attachSymbol = null, IEnumerable<Transaction.Output> attachTargets = null);

Is there any documented way to call MultiSig wallet and pass signatures to it ?

I am trying to invoke a smartcontract and make a transaction over a private network but there is some issue that i am unable to resolve. Will be grateful if someone help me solve the issue.

This is my smart contract code:

This is how i am trying to invoke the contract from api code:

Transaction and result are always returned as null as shown below

Since there are already lots of demos, the readme should be updated with a table containing list of demos and descriptions / notes for each

The ScriptBuilder is emitting a trimmed hexstring for BigInteger representation. Usually, the BigInteger is represented as a 16 character hexstring. Trimming may occur for excess zeroes. However, this trimming is causing an issue as the node seems to be unable to process the trimmed BigInteger.

Take for example, 78a1552b1a4cf1eb04a9cfa4998965603a0beb148a80354f0d2d58ef5aeb58c2 on testnet. The VM script uses a trimmed hexstring for the amount and the user reports that the transaction did not effect a change in tokens.

I had this experience in neon-js too and the solution was to always use 8 bytes to represent a BigInteger.
