It would be great if the filled out invoke screen could be saved as a "template" for later use so that the user doesn't have to populate all the params each time.

In the neo-debugger, we're able to also send assets along with a contract invocation. This functionality, while valid, is missing from neo-gui. It'd be hella useful to be added!

This is extremely minor, but windows like the "Parameter Editor" should have field boxes that shrink the same way when the gui window is slaked. Currently, the "Hex Encode" checkbox even vanishes when the window is too small. I noticed this when making the video. And I'm not sure why the window closes upon "insufficient funds".

Hi.

I watched the video, but really, passing parameters when involing the contract is not clear at all.

So here is what I am trying to do:

http://prntscr.com/hgmflg

I want to pass a simple string to the contract. But when passing "Test" as parameter, it changes to ByteArray automaticaly. And I got the error displayed in the screenshot, what ever the tye of parameter I put.

Can someone explain clearly how to pass parameters?

Once it fails, it's repeatable. neo-gui will sync for a few blocks and then fails within a few seconds of starting. I'm running neo-gui in the Visual Studio debugger.

Hi!
Could we have compiled binaries released on GitHub here for those of us not into using Windows platforms?

I want to invoke transfer method which is as following.

public static bool Transfer(StorageContext context, byte[] from, byte[] to, BigInteger amount)
{
            if (from.Length != 20 || to.Length != 20) return false;
            if (amount <= 0) return false;
            if (!Runtime.CheckWitness(from)) return false;
            if (from == to) return true;

            BigInteger fromBalance = Storage.Get(context, from).AsBigInteger();
            if (fromBalance < amount) return false;
            if (fromBalance == amount)
                Storage.Delete(context, from);
            else
                Storage.Put(context, from, fromBalance - amount);

            BigInteger toBalance = Storage.Get(context, to).AsBigInteger();
            Storage.Put(context, to, toBalance + amount);
            Transferred(from, to, amount);
            return true;
}

method invoke is not succeeded because it stops at line 5 if (!Runtime.CheckWitness(from)) return false;, which always returns false.

How can I make CheckWitness return true?
Thanks for help in advance.

So I suppose this is one for @birmas!

I don’t know if this was intended or serves another purpose, but when the last param type is 10 (an object array) we see an extra array for additional params in the UI, so 2 arrays in total. I get that this seems to be a catch-all for extras but when the last declared param is an array it doesn't make sense to have it.

And another thing I’ve noticed as a bonus: The string type (07) is not a registered as "string" in the UI but just shows as "7".

While trying to build the gui, I got the following error:

Ungültige ResX-Datei. Der angeforderte Wert "Ctrl" konnte nicht gefunden werden.
Zeile 573, Position 5.

Translated: Invalid ResX-File. The required value "Ctrl" could not be found.

As it turns out, I had to translate

Ctrl

to

Strg

(for Germany), which fixed the error. This fix may be different if the locale of your System or Visual Studio is different.

The dialog box opens, I can input a "New value" for my parameters (a string and an object[] array), but I cannot save and exit that dialog window, keeping my changes.

I am creating an ICO and want to test it on privatenet.
The neo-gui allows to invoke smart contract but does not send Neo asset token along with the invocation.
The Neon wallet provides to participate in ICO but it does not work on privatenet setup using docker.

Any workaround to call ICO smart contract's mintToken along with some Neo token transferred?

Parameters link at https://github.com/CityOfZion/neo-gui-developer/blame/master/README.md#L57 is broken because https://github.com/CityOfZion/docs does not exist.

Not able to set parameters while invoking the contract, there is no update button.

Hi,

I have compiled(built) the neo-gui-developer in release and debug modes. While neo-gui synced on testnet, the neo-gui-developer (both release and debug versions) crashes on some block while syncing on testnet.

I think the source codes have to be reviewed.

There were problems in neo-gui-developer also in:

Program->InstallCertificate():

System.TypeInitializationException: 'The type initializer for 'Neo.Properties.Settings' threw an exception.'

Why ?

How to get it synced to the testnet?

Kind Regards.

Hi City of Zion Team,

On 12/27/2016 I started a token transfer of 11,067 NEO to my Bittrex Wallet, but for an unkown reason 20,843 NEO have been transfered in total.

The problem is that 9,776 of the 20,843 NEO Coins have been transfered as unspent to a wallet I don't have access to.

The details are the following:

-transaction of 20,843 NEO in total on 12/27/2016, 12:15:11 (transaction Hash d832459fcbf9c1838d4ccc173cda4bc92a34efa992c5269cc30b31155b438b7b from wallet adress ATa1nvgygN6c8ACL4PATFMGXe3GVraKNeY )

-11,067 NEO went to my Bittrex Wallet AYmEw36bF54aX1xK9GvUiHicfL56S1MRgT

-9,776 NEO went to unknown an adress AbEM51hVzJsf65Lop9WbLjLjEdenbZK5zQ as unspent

Is there a way to get me back access to my unspent NEO?

Thanks for your help in advance

Martin

There are huge changes in this commit;
neo-project/neo-gui-2.x@adefd4b
Merging this will be hard.

i'm getting a compile time error
'CX509PrivateKey' does not contain a definition for 'AlgorithmName' and no extension method 'AlgorithmName' accepting a first argument of type 'CX509PrivateKey' could be found
if anyone suggest a fix that will be great, if not can someone send me a x64 version .exe file?

You can call it a usability or functionality or workflow issue but it appears that the contract deployment transaction doesn't happen (execute) until you click the Test button on the Invoke Contract dialog. This is counter-intuitive and will lead to a lot of "user error". Checkout the function btnTestScript_Click() here:

People are going to expect the deployment should take place when you click the Deploy button in the Deploy Contract dialog. This should be refactored.

This would be really helpful for debugging
