kandi X-RAY | prova Summary
Prova is a distributed consensus system for digital asset tokens written in Go (golang). Prova was built to support RMG, a digitized form of gold introduced by [The Royal Mint] and CME Group. Features include:. It downloads, validates, and serves a block chain using consensus rules for block acceptance. It includes a full block validation testing framework. It relays newly generated blocks, maintains a transaction memory pool, and relays individual transactions that have not yet made it into a block. It ensures all individual transactions admitted to the pool follow the rules required by the block chain. Prova does NOT include wallet functionality. This means you can’t actually make or receive payments directly with Prova. That functionality is provided by Prova wallet implementations.

QUESTION
Hello i have this code to display an immage saved on my filesystem on broswer:
...ANSWER
Answered 2021-Jun-15 at 09:12Your code first tests that your input exists (as a File
) and is not a directory, then you go ahead and try to read it as a resource from the class path using getClass().getResourceAsStream(path)
. This is usually not what you want.
Try instead InputStream in = new FileInputStream(path);
.

i'm trying to make a TextField that is a minimum size, and that expands around the text being written inside it, how can i achieve this?
This is my test code
...ANSWER
Answered 2021-Jun-12 at 06:27Using Spacer
with Modifier.weight(1f)
in between will make it work.
I would suggest replacing TextField
with BasicTextField
to get finer control over its look (specifically achieving smaller minimum width than MinWidth
default value of 280.dp
).

I'm writing a Google Apps Script Web App, I'm facing a problem.
From server side I return the base64 encoded html code of a page:
...ANSWER
Answered 2021-May-18 at 13:17I believe your goal and your current situation as follows.
- You want to convert the HTML data to a PDF data as the raw HTML code.
- From
I want to download the base64 (is an html RAW content) as a pdf file
, I thought that the PDF data has the raw HTML code.
- From
- You want to make users download the HTML data as a PDF file.
var encoded = window.value;
of your Javascript side is the value ofencoded
from the function ofgetRAW()
of Google Apps Script.
- In this case, in order to convert the raw HTML code (text data) to a PDF data, I would like to propose to use the Google Document. When Google Document is used, the text data can be converted to the PDF data.
When above points are reflected to your script, it becomes as follows.
Modified script:In this case, please modify getRAW()
at Google Apps Script side as follows.
QUESTION
I'm trying to create a hydra-style bot discord with an embed that automatically gets assigned control reactions with which I can pause, resume, stop the music etc ...
I have a problem, if I try to start the command to pause typing '*psres' everything works fine, however, if I try to start the pause command via the reaction it gives me the following error:
...
ANSWER
Answered 2021-Apr-17 at 03:55In your setup.js file the command handler is client.commands.get('psres').execute(message, client, args)
with message, client and args as parameters. But in the pause/resume command file, you are executing execute (client, message, args)
with client, message and args as param. The objects are not what you think it is because if you compare both of them, the parameters are not matching/placed in wrong order. So matching the parameters either according to the setup commands param or the way you are executing in the pause/resume command.

Answered 2021-May-14 at 10:08It looks like you're using this: https://github.com/tpoisot/bipy and that prova.py
is your addition (it would be nice if you include this kind of information in your question in future questions!)
The problem is that bipartite_class
is not a free-standing module, but is a part of the package bipy
. That means you need to import it from outside the package. You need to move prova.py
one directory up, to bipy-master
, and change its contents to:

QUESTION
I'm trying to learn GUI in C so im learning the windows.h library. for that im watching a series of video made by a guy. here's the link: https://www.youtube.com/playlist?list=PLWzp0Bbyy_3i750dsUj7yq4JrPOIUR_NK third video.
my understanding of the library is very limited and where it happens some problem i dont really know where to start off because by the compiler you dont get any kind of error.
so here's my problem: im making as you can see at the end of the code two child windows, one that just print a text as static and the other let you enter text in the window, but when i type in the second child window it starts to flicker and i cant see the text that i putted until i highlight it.
...ANSWER
Answered 2021-May-05 at 19:02The WM_COMMAND
message is sent not only when menu items are selected or when accelerator keys are pressed. Many controls such as the edit control send it as notification message.
In your message handler, you handle only the menu items. All other COMMAND_WM
s (and even the menu selections, because the breaks
there just break out of the inner switch) fall through to WM_CREATE
and create new controls.
That's where the flicker comes from: When you type something, the edit box is notified, tries to handle the notification WM_COMMAND
message and creates a new window on top of the one that you were typing in.
You need a break
for the WM_COMMAND
after the inner switch
block.
