Data not rendering after OnCLick
|
<p>I am trying to display the data after hitting the "Show the data" button. I can see the data in the console but it is not being display on the page. Could anyone help me out and guide me to let me know what is my mistake. Been struggling for days now. Below is my code. I have edited critical information in the code for obvious security reasons. Any help would be appreciated. Thank you.</p>
<p>axios.post is used to post the token and
axios.get is used to fetch the data from the backend and display it.</p>
<hr />
<pre><code>
import {useState} from 'react';
import axios from 'axios';
import '../App.css'
var raw = JSON.stringify({
username: "xyz",
password: "xyz"
});
const type_no = '88';
const URL = `example url://abc.com/abc/${type_no}`;
function getToken(){
const promise = axios.post("example url://abc.com/", raw)
const id = promise.then((response) => response.data.IdToken)
return id
};
const App = () => {
const [data, setData] = useState({data: []});
const [isLoading, setIsLoading] = useState(false);
const [err, setErr] = useState('');
const handleClick = async () => {
getToken().then(token => {
setIsLoading(true);
const config = {
headers: {
'Authorization': 'Bearer ' + token,
'Content-Type': 'application/json',

};
const {data} = axios.get(URL, config)
.then((response) => {
console.log(response);
setData(response.data);
})
.catch((error) => {
console.log(error);

How can I get all the XSD validation errors from an XML file in dotnet?
|
<p>Caveat: I'm fairly new to .NET so I'm unfamiliar with a lot of libraries available.</p>
<p>I have developed a function app using java that I'm having to port over to C#. I am currently using the built in XSD validation library for .NET and my file <em>is</em> being successfully validated, however when testing the results against the java version there are significantly less validation errors being reported in the .NET version.</p>
<p><strong>Root XSD file</strong></p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>

</code></pre>
<p>My issue appears to be occuring when there is a missing element in one of my included xsd files, when this happens all subsequent errors in that xsd file are not reported (e.g. if the initial element is missing, no other validation errors are reported for that xsd file and the validation moves on to the next included xsd).</p>
<p>My code is pretty much lifted straight from the <a href="https://docs.microsoft.com/en-us/dotnet/standard/data/xml/xml-schema-xsd-validation-with-xmlschemaset" rel="nofollow noreferrer">Microsoft documentation</a>:</p>
<pre><code> public XsdValidationResult ValidateXml(string filePath)
{
var schemas = GetSchemas();
var settings = new XmlReaderSettings();
settings.Schemas.Add(schemas);
settings.ValidationType = ValidationType.Schema;
settings.ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings;
settings.ValidationEventHandler += XsdValidationEventHandler;
using var reader = XmlReader.Create(filePath, settings);
var doc = new XmlDocument
{
PreserveWhitespace = true
};
doc.Load(reader);
return GetValidationResult();
}
private void XsdValidationEventHandler(object sender, ValidationEventArgs e)
{
if (e.Severity != XmlSeverityType.Error) return;
var sb = new StringBuilder();
sb.Append(e.Message);
sb.Append($" Line Number: {e.Exception.LineNumber}");
sb.Append($" Position: {e.Exception.LinePosition}");
_errors.Add(sb.ToString());
}
</code></pre>
<p>The validation error I get looks something like this (before moving on to the next schema):</p>
<blockquote>
<p>The element 'subSchema.elementGroup' in namespace 'namespace' has
invalid child element 'subSchema.element02' in namespace 'namespace'.
List of possible elements expected: 'subSchema.element03' in namespace
'namespace'.</p>
</blockquote>
<p>I did come across this possible explanation of what is happening in the Microsoft docs:</p>
<blockquote>
<p>When the new XmlReader has been closed, the original XmlReader will be
positioned on the EndElement node of the sub-tree. Thus, if you called
the ReadSubtree method on the start tag of the book element, after the
sub-tree has been read and the new XmlReader has been closed, the
original XmlReader is positioned on the end tag of the book element.</p>
</blockquote>
<p>but this behaviour is different from what I need :(</p>
<p>Ultimately my question is, is there a way to continue parsing the XML file after an element has been discovered as missing (either using a different library or through the included .NET library) so as to capture all XSD validation errors?</p>

django field using pictures instead of text

<p>If I choose one of whose input value is radio in HTML and submit, the selected one is delivered to the models, and finally, I want to retrieve the selected image from HTML again.
But I can't even get a clue. What should I do?
And I also wonder how to connect and use these with forms.py and html.
I want to know the exact answer because the image field is set as a temporary measure.</p>

In R, create a new column based on the order of a 2nd column grouped by a 3rd column
|
<p>This is very similar to some other questions, but I wasn't quite satisfied with the other answers.</p>
<p>I have data where one column is the outcome of a Latin Square study design, where a participant had three conditions that could have come in six possible orders. I do not have a variable that indicates the order that the participant actually received the study conditions, and so need to create one myself. Here is my current and desired output using a fake example from the first three participants:</p>

#> The following objects are masked from 'package:base':
#>
#> intersect, setdiff, setequal, union
(current <- tibble(
participant = c(1,1,1,2,2,2,3,3,3),
block_code = c("timed", "untimed", "practice", "untimed", "practice", "timed", "timed", "untimed", "practice")
))

Can't update user's info clicking on a submit

graphql cache DataIdFromObject not causing React re-render
|
<p>I have two mutations <code>onLike</code> and <code>onSubmit</code> defined in one react component. For <code>onLike</code> mutation, I can use cache with <code>DataIdFromObject</code> to update the data without refetching the data with either <code>this.props.data.refetch()</code> or <code>refetchQueries: []</code>. BUT not for <code>onSubmit</code> mutation. </p>
<p>// --- React component</p>
<pre><code>onSubmit(e) {
e.preventDefault();
this.props
.addLyricQuery({
variables: {
content: this.state.content,
songId: this.props.params.id,
},
});
}
onLike(id, likes) {
this.props.likeLyricQuery({
variables: { id },
optimisticResponse: {
__typename: "Mutation",
likeLyric: {
id,
__typename: "LyricType",
likes: likes + 1,
},
},
});
}
<button onClick={() => this.onLike(lyric.id, lyric.likes)}>
<button onClick={e => this.onSubmit(e)}>Submit</button>
</code></pre>
<p>// --- apollo connect</p>
<pre><code>const enhancer = compose(
graphql(fetchSongQuery, {
options: props => ({
variables: {
id: props.params.id,
},
}),
}),
graphql(addLyricQuery, { name: "addLyricQuery" }),
graphql(likeLyricQuery, { name: "likeLyricQuery" })
);
export default enhancer(SongDetail);
</code></pre>
<p>// --- addLyric Query</p>
<pre><code>import gql from "graphql-tag";
export default gql`
mutation AddLyricToSong($content: String, $songId: ID) {
addLyricToSong(content: $content, songId: $songId) {
id
title
lyrics {
id
content
}
}
}
`;
</code></pre>
<p>// --- like query</p>
<pre><code>import gql from "graphql-tag";
export default gql`
mutation LikeLyric($id: ID!) {
likeLyric(id: $id) {
id
likes
content
}
}
`;
</code></pre>
<p>// --- apollo store</p>
<pre><code>const client = new ApolloClient({
dataIdFromObject: o => o.id
});
</code></pre>
<p><strong>What do I expect to see?</strong></p>
<p>I expect the behavior between <code>onSubmit</code> and <code>onLike</code> to be the same. So when I click on either button, it should only query once, without needing to refetch the data.</p>
<p><strong>What do I see?</strong></p>
<p><code>onLike</code> works as expected. When clicked, it only issues one mutation, and the react component is rendered immediately. </p>
<p><code>onSubmit</code> leads me to a blank page, then once I refresh the page, the new data displays. I can make it work by using <code>refetch</code> or <code>refetchQueries: []</code> but that is besides the point.</p>

<p>Already tried below options:
(1)used "tasket" to pin the application to a particular CPU
(2)used "nice" & "renice" to change the priority of process
(3)tried executing same source code from /tmp directory to ensure there was no network lag issues.
(4)there is no load on the machines.
(5)Have also tried using -o2, -o3 optimizations.
(6)tried executing with sudo, still i notice consistent time difference in the execution on source code on two different machines which have same configurations.</p>
<p>Could someone let me know as to why same source code being executed on two different AMD machines having same configurations is providing different "user" time</p>

Google App Script User Scope Approval for new scope
|
<p>I've added the <code>script.external_request</code> scope to my GMail Add-on so that I can connect to and store information in a MySQL dB.</p>
<p>The scope was submitted and approved by Google OAuth and Marketplace SDK.</p>
<p>If I run the script in the editor from the HEAD deployment, I get the OAuth approval workflow and the script connects to the database.</p>
<p>In the deployed version I keep getting the following error:</p>
<p><code>You do not have permission to call Jdbc.getConnection. Required permissions: https://www.googleapis.com/auth/script.external_request</code></p>
<p>It seems to me that the end users are not getting a trigger to accept the new scope from the UI of the addon.</p>
<p>Is there a way to force the OAuth workflow re-authorization from the addon UI?</p>
<p>Or is there something else going on here?</p>
<p><strong>ADDED INFO</strong></p>
<p>I used Aaron's suggestion on the QuickStart to add a logging check to see if the required permissions are present. At least this will point to if this might be a red-herring.</p>
<pre><code> if (authInfo.getAuthorizationStatus() ==
ScriptApp.AuthorizationStatus.REQUIRED) {
Logger.log(`${user} - Missing required scope authorizations`)
}else{
Logger.log(`${user} - Required scope authorizations present`)
}
</code></pre>
<p>Naturally in the 12hrs this has been present, no user has opened the app. So will have to report back later.</p>
<p>Also adding my appscript.json manifest</p>

Elixir Wallaby crashes on mix test

Image Isn't upating when going back to main activity
|
<p>Ok, I've got two activities, in the main activity there is an image button that takes you to a profile page activity where you can click on another image button and access your photo gallery to set a profile picture which is saved into Firebase storage and as a url in the database. This all works, the problem is that after you do all this and go back to the main activity (I'm overriding the back button and starting a new main activity) the image button shows the previous profile image despite Log.d checks reporting that I am accessing the updated url. Even stranger, if I go into the profile activity again it will display the update profile pic and when I go back to the main activity again the new image will now be displayed correctly. </p>

Semaphore time out while looping thu serialport.open()
|
<p>I have a piece of code which scans for all available comports. And than it will try to find the correct device by opening the comport and send a message, if the message is correct I have find the correct device. Now this worked pretty well but now I discovered a bug. I think I know what is happening but I'm not sure if this is the reason and also how to solve it.</p>
<p>I get the error message: "The semaphore timeout period has expired."
Searching on Google it told me this message appears when there are problems with receive data back (files or so). I think when reaching the particular where the error appears it is one that is already open and connected to a device.</p>
<p>I wrote my code like this:</p>
<pre><code> // Detect VM25 and show connection is established
string device;
string CheckConnection;
string[] ports = SerialPort.GetPortNames();
int count = 0 ;
//Test which enabled port is the VM25.
foreach (string port in ports)
{
serialPort1.PortName = port;
serialPort1.ReadTimeout = 2000;
serialPort1.Open();
// Display each port name to the console.
Console.WriteLine(port);
if (serialPort1.IsOpen)
{
device = "";
serialPort1.WriteLine("#S" + Environment.NewLine);
serialPort1.WriteTimeout = 1000;
try
{
answer = serialPort1.ReadTo("/a");
serialPort1.ReadTimeout = 3500;
serialPort1.Close();
if (answer != "")
{
device = answer.Substring(0, 4);
//Find the correct response from the Com port where the VM25 is connected
if (device == "VM25")
{
statusLblDevice.ForeColor = Color.LawnGreen;
statusLblDevice.Text = port + " - " + device + " - Connected";
VM25Port = port;
serialPort1.PortName = VM25Port;
serialPort1.Open();
serialPort1.WriteLine("#H" + Environment.NewLine);
serialPort1.WriteTimeout = 2000; //Timeout for writing the comment
string input = serialPort1.ReadTo("/a");
serialPort1.ReadTimeout = 5500; //Timeout for reading the data
string totalMeasurements = "Measurements: " + input.Substring(9, 3); //Take the amount of measurements into a string
MeasTotal = int.Parse(input.Substring(9, 3));
string totalFFT = "FFTs: " + input.Substring(18, 5); //Take the amount of FFTs into a string
statusLblMeas.Text = totalMeasurements;
statusLblFFT.Text = totalFFT;
FFTtotal = int.Parse(input.Substring(18, 5));
serialPort1.Close();
}
}
}
catch (TimeoutException)
{
serialPort1.Close();
}
}
}
</code></pre>
<p>I think I need to adjust my code such that if the comport is already open it skips the and goes to the next item in the <code>foreach</code> loop? Or are the any better ways to solve this?</p>
<p>Thanks in advance</p>

Using an if statement to update OR insert into

<p>I have the following code which up dates my database table perfectly. However, I now wish it to either, update an existing row if the value of $status is 'open', or create a new row if the value of $status is 'completed'.</p>
<p>This is my code so far;</p>

<p>I've tried =, == and === for comparing $status. If I take it back a notch and echo either 'open' or 'completed' depending on the value of $status, it works fine, echoing the correct answer each time.</p>
<p>Advice is appreciated.</p>

DependencyProperty not update
|
<p>I have a user control with IsChecked Property</p>
<pre><code>public static readonly DependencyProperty IsCheckedProperty = DependencyProperty.Register(
"IsChecked", typeof(bool), typeof(LabeledCheckbox),new FrameworkPropertyMetadata
{
DefaultValue = false,
BindsTwoWayByDefault = true,
});
public bool IsChecked
{
get { return (bool)this.GetValue(IsCheckedProperty); }
set { this.SetValue(IsCheckedProperty, value); }
}
</code></pre>
<p>I'm bounding the IsChecked Property to a another property called active
and i create a checkbox that the IsChecked Property also bound to the active property</p>
<pre><code><controls:LabeledCheckbox x:Name="ccc" Tag="Active" CheckedColor=" #33cc00" UncheckedColor="#cc2900" CheckedContent="hello" UncheckedContent="world" IsChecked="{Binding Active, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" FontSize="25" Margin="5" Width="100"/>
<CheckBox IsChecked="{Binding Active, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>
</code></pre>
<p>The checkbox is update correctly but the controls:LabeledCheckbox not update
the other DP in controls:LabeledCheckbox are working great.</p>
<p>why the IsChecked property not updating?
tried to use RelativeSource={RelativeSource AncestorType={x:Type Window}}
on the controls:LabeledCheckbox like this:</p>
<pre><code><controls:LabeledCheckbox x:Name="ccc" Tag="Active" CheckedColor=" #33cc00" UncheckedColor="#cc2900" CheckedContent="שלום" UncheckedContent="עולם" IsChecked="{Binding Active, RelativeSource={RelativeSource AncestorType={x:Type Window}}, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" FontSize="25" Margin="5" Width="100"/>
</code></pre>
<p>tried one way to source</p>
<p>the set of IsChecked never triggered unless i set True ao false directly and not binding.</p>
<p><strong>UPDATE</strong>
Adding the UserControl's full code:</p>
<pre><code>public partial class LabeledCheckbox : UserControl

Android Eclipse: database doesn't seem to work when APK is installed to an external device
|
<p>I am a beginner mobile developer and I am developing a directory app using eclipse for android. I am not really good in coding and programming so I really need help. </p>
<p>My app works good in my laptop, in eclipse emulator but when I run it in my phone, or manually copy the apk and install it in my phone, the app works from the login activity, but when I start searching in the main activity, nothing happens, <strong>no error warning</strong>, <strong>no logcat error</strong> or anything else.</p>
<p>I'm suspecting that the database isn't installed together with the apk, I have no idea what's happening and what to do, please help. Thanks in advance.</p>

Why decodeAudioData for Icecast stream only works on Desktop Chrome browser
|
<p>I have a livestream that is served through Icecast as an audio/mpeg. I use the following code to grab the audio from a livestream to listen to the audio:</p>
<pre><code> function playLiveAudio() {
// Fix up prefixing
window.AudioContext = window.AudioContext || window.webkitAudioContext;
var context = new AudioContext();
var offset = 0;
var byteOffset = 0;
var minDecodeSize = 4096; // This is your chunk size
var request = new XMLHttpRequest();
request.onprogress = function(evt)
{
if (request.response)
{
var size = request.response.length - byteOffset;
if (size < minDecodeSize) return;
// In Chrome, XHR stream mode gives text, not ArrayBuffer.
// If in Firefox, you can get an ArrayBuffer as is
var buf;
if (request.response instanceof ArrayBuffer)
buf = request.response;
else
{
ab = new ArrayBuffer(size);
buf = new Uint8Array(ab);
for (var i = 0; i < size; i++)
buf[i] = request.response.charCodeAt(i + byteOffset) & 0xff;
}
byteOffset = request.response.length;
context.decodeAudioData(ab, function(buffer) {
playSound(buffer);
}, function(error) {
console.log(error);
});
}
};
request.onloadend = function(evt) {
console.log(evt);
};
request.open('GET', liveURL, true);
request.responseType = "stream"; // 'stream' in chrome, 'moz-chunked-arraybuffer' in firefox, 'ms-stream' in IE
request.overrideMimeType('text/plain; charset=x-user-defined');
request.send(null);
function playSound(buffer) {
source = context.createBufferSource(); // creates a sound source
source.buffer = buffer; // tell the source which sound to play
source.connect(context.destination); // connect the source to the context's destination (the speakers)
source.start(offset); // play the source now
// note: on older systems, may have to use deprecated noteOn(time);
offset += buffer.duration;
}
}
</code></pre>
<p>I tried changing stream to moz-chunked-arraybuffer and seeing if I could manipulate the audio buffer but it doesn't seem to make a difference - I always get a decode promise rejection in Safari with no further message, or a decode audio data error in Firefox.</p>
<p>For some reason, it only works on Desktop Chrome - it doesn't work on any versions of Firefox, Safari or Mobile Chrome. How can decodeAudioData() be made to work on all environments? In Firefox I receive the error: cannot decodeAudioData(). I can set an audio element to livestream the URL but then there is an 8 second delay. This code achieves a 1 second delay.</p>

ImputError: cannot import name "function" from "module.py"
|
<p>In Jupyter Notebook:
repo:</p>
<ul>
<li>module: featurestorehouse.py</li>
<li>main: preprocessing.ipynb</li>
</ul>
<p>I have several functions in featurestorehouse.py, I need to import most of them, and some of them, particularly the ones I wrote earlier in time, work when I import them. However, the more recent ones don't want to be imported as it gives an ImputError.</p>
<p>I checked and changed where necessary, the necessary modules are imported in the module file, I tried putting the imports specific to a function within the function definition - which didn't fix anything, and I tried to not import the functions separately but adding 'fs.' in front of each to reference featurestorehouse as fs.</p>
<p>The function and module:</p>
<pre><code># # Feature Engineering #
import pandas as pd
import numpy as np
import spacy
import re
import string
from statistics import mean
from collections import Counter
</code></pre>
<p>Some of the functions that do not work:</p>
<pre><code># Phrasal complexity
## reference to Martinez (2018)
def nr_np(series):
"""Calculates nr of noun chunks in the texts."""
nlp = spacy.load("en_core_web_sm")

nps = []
for nc in text.noun_chunks:
nps.append(np)
return len(nps)
def count_np(df, word_count_column, np_count_column):
"""Divides number of words by number of noun phrases."""
try:

try:
rel_np = df[np_count_column]/df[word_count_column]
return rel_np
except 'ZeroDivisionError':

</code></pre>
<p>How I tried to implement them in my main notebook:</p>
<pre><code># Adding Custom Feature Columns

</code></pre>
<p>The last set underneath "### apply function" gives an error when I import featurestorehouse.py as fs and add fs. to each function in the main notebook (obviously it doesn't get to this point when I'm importing each function separately from featurestorehouse.py).</p>
<p>The error:</p>
<pre><code>ImportError Traceback (most recent call last)

ImportError: cannot import name 'nr_np' from 'featurestorehouse' (C:\Users\tdems\Jupyter\CEFR_AES_dissertation\featurestorehouse.py)

<p>Does anyone know what's up with this? There's no circular dependencies involved as far as I know. There's a lot of other notebooks in the repo but that's never been a problem up till now.</p>

How to repeatedly loop over subsets of a collection determined by an attribute of the items?
|
<p>I have a collection of objects owned by a struct <code>Manager</code>. These objects have optional attributes such as <code>printable</code> or <code>dynamic</code>. I want to repeatedly loop over all printable objects to print them and loop over all dynamic objects to update them. My rather naive implementation is this:</p>
<pre><code>struct Object {
state: i32,
printable: Option<i32>,
dynamic: Option<i32>
}
struct Manager {
objects: Vec<Object>,
}
impl Manager {
fn print_objects(&self) {
for o in &self.objects {
if let Some(i) = o.printable {
print!("{}: {}, ", i, o.state);
}
}
println!();
}
fn update_objects(&mut self) {
for o in &mut self.objects {
if let Some(i) = o.dynamic {
o.state += i;
}
}
}
}
fn main() {
let mut mgr = Manager{objects: Vec::new()};
mgr.objects.push(Object{state: 0, printable: Some(10), dynamic: None});
mgr.objects.push(Object{state: 0, printable: None, dynamic: Some(1)});
mgr.objects.push(Object{state: 0, printable: Some(20), dynamic: Some(2)});
for _ in 0..3 {
mgr.update_objects();
mgr.print_objects();
}
}
</code></pre>
<p>This solution has the drawback that it needs to loop over all objects and check each for the appropriate flag. Assuming that only a small fraction of the objects are dynamic, I'd rather avoid looping over all of them. In C++ I would simply create a list of pointers to the dynamic objects and loop over that. Attempting this: </p>
<pre><code>struct Manager<'a> {
objects: Vec<Object>, // objects owned by Manager
dynamic: Vec<&'a Object> // references to dynamic objects
}
impl<'a> Manager<'a> { /* ... */ }
fn main() {
let mut mgr = Manager{objects: Vec::new(), dynamic: Vec::new()};
mgr.objects.push(Object{state: 0, printable: Some(10), dynamic: None});
mgr.objects.push(Object{state: 0, printable: None, dynamic: Some(1)});
mgr.objects.push(Object{state: 0, printable: Some(20), dynamic: Some(2)});
mgr.dynamic.push(&mgr.objects[1]);
mgr.dynamic.push(&mgr.objects[2]);
for _ in 0..3 {
mgr.update_objects(); // can't mutably borrow because of reference held by mgr.dynamic
mgr.print_objects();
}
}

<p>It seems to be a very basic problem that I can't keep a reference to elements in <code>Manager.objects</code> and at the same time borrow it mutably. Thus, I've started to doubt my whole approach. Is there an idiomatic way to implement such a pattern in Rust?</p>
<p>I believe that keeping references to objects prevents me from mutating them, but I'd be happy to learn a way around that. A future goal would be to change <code>printable</code> or <code>dynamic</code> during update, but I'd like to figure out the basic stuff before tackling that step.</p>

Using jQuery each, scrollTop() returns zero

<p>I'm having a problem using a jQuery <code>scrollTop()</code> function with <code>$.each.</code> Every time, no matter how many <code><div class="panel"></div></code> elements are, <code>scrollTop()</code> function returns zero.

Notification not displaying on android device. (Azure notification hub)
|
<p>I'm trying do send a push notification to my android emulator. When the notification is sent, it receives the notification but does not display it. </p>
<p>I'm using this code to display it. </p>
<pre><code>void SendNotification(string messageBody)
{
var intent = new Intent(this, typeof(MainActivity));
intent.AddFlags(ActivityFlags.ClearTop);
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.SetContentTitle("FCM Message")
.SetSmallIcon(Resource.Drawable.icon)
.SetContentText(messageBody)
.SetChannelId("my-chanel")
.SetAutoCancel(true)
.SetContentIntent(pendingIntent)
.SetSound();
var notificationManager = NotificationManager.FromContext(this);
notificationManager.Notify(0, notificationBuilder.Build());
}
</code></pre>
<p>But when the notification is received nothings happens and the logs of my devices gives me this: </p>
<pre><code>[Mono] Assembly Ref addref ODEON.Android[0xa31db5c0] -> System.Core[0xa1f2f900]: 7

Adding timestamp on the top of the plot using Matplotlib

<p>Is there a way to add timestamp <code>t=0</code> on the top of the plot at the specific location as shown in the expected output?

How to remove space between expanded ExpansionPanels in ExpansionPanelList?
|
<p>This is an example code for <code>ExpansionPanelList</code></p>
<pre><code>import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
static const String _title = 'Flutter Code Sample';
@override
Widget build(BuildContext context) {
return MaterialApp(
title: _title,
home: Scaffold(
appBar: AppBar(title: const Text(_title)),
body: const MyStatefulWidget(),
),
);
}
}
// stores ExpansionPanel state information
class Item {
Item({
required this.expandedValue,
required this.headerValue,
this.isExpanded = false,
});
String expandedValue;
String headerValue;
bool isExpanded;
}
List<Item> generateItems(int numberOfItems) {
return List<Item>.generate(numberOfItems, (int index) {
return Item(
headerValue: 'Panel $index',
expandedValue: 'This is item number $index',
);
});
}
class MyStatefulWidget extends StatefulWidget {
const MyStatefulWidget({Key? key}) : super(key: key);
@override
State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}
class _MyStatefulWidgetState extends State<MyStatefulWidget> {
final List<Item> _data = generateItems(8);
@override
Widget build(BuildContext context) {
return SingleChildScrollView(
child: Container(
child: _buildPanel(),
),
);
}
Widget _buildPanel() {
return ExpansionPanelList(
expansionCallback: (int index, bool isExpanded) {
setState(() {
_data[index].isExpanded = !isExpanded;
});
},
children: _data.map<ExpansionPanel>((Item item) {
return ExpansionPanel(
headerBuilder: (BuildContext context, bool isExpanded) {
return ListTile(
title: Text(item.headerValue),
);
},
body: ListTile(
title: Text(item.expandedValue),
subtitle:
const Text('To delete this panel, tap the trash can icon'),
trailing: const Icon(Icons.delete),
onTap: () {
setState(() {
_data.removeWhere((Item currentItem) => item == currentItem);
});
}),
isExpanded: item.isExpanded,
);
}).toList(),
);
}
}
</code></pre>
<p>And it gives the following result:</p>
<p><a href="https://i.stack.imgur.com/orXvY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/orXvY.png" alt="enter image description here" /></a></p>
<p>As you see there is grey space between <code>Panel 0</code> and <code>Panel 1</code>, and between <code>Panel 1</code> and <code>Panel 2</code>. Could anyone say how to remove this space, if it is possible?</p>

Suppressed the virtual mechanism by storing object explicitly as base class?
|
<p>As you'd expect, I've arrived at a question I can't answer and I can only guess.</p>
<p>Runtime polymorphism is the goal, using the virtual mechanism, but the result I'm getting is as if I called the method while suppressing it; like I called the base class method.</p>
<p>I can only guess then that I am somehow doing that, the call is from an object that <em>is</em> a base class, although it was constructed as a derived class. So, constructed as a derived, stored as a base.</p>
<p>I do store this as a static base class variable within a cpp and interfaced with multiple extern functions to access elsewhere. (perhaps, that's the gotcha?)</p>
<p>GameScene.h:</p>
<pre><code>class GameScene {
public:
GameScene() { SceneInit(); }
~GameScene() { }
virtual void LevelInit() { } // gcc complains w/o {}
void SceneInit();
virtual void UpdateLevel( const float& timeDelta ) { } // gcc complains unless {} added
void UpdateScene( const float& timeDelta );
};
extern void NewScene( const GameScene& level );
extern void UpdateScene( const float& timeDelta );
class TestLevel : public GameScene {
public:
TestLevel() { SceneInit(); }
// implementation here in header
void LevelInit() override
{
// level-specific initialization that is apparent at runtime
}
void UpdateLevel( const float& timeDelta ) override
{
// level-specific checks and performance
// but, to test, I simply log "This is the test level"
}
};
class TutorialLevel : public GameScene {
public:
TutorialLevel() { SceneInit(); }
// implementation here in header
void LevelInit() override
{
// level-specific initialization that is apparent at runtime
}
void UpdateLevel( const float& timeDelta )
{
// level-specific checks and performance
// debug log "This is the tutorial level"
}
};
</code></pre>
<p>GameScene.cpp:</p>
<pre><code>#include "GameScene.h"
static GameScene currentScene; // I am now wondering if this pattern is the problem (by explicitly storing this as the base class)
extern void NewScene( const GameScene& level )
{
currentScene = level;
}
extern void UpdateScene( const float& timeDelta )
{
currentScene.UpdateScene( timeDelta );
}
GameScene::SceneInit()
{
// general init
LevelInit(); // this _properly_ calls the subclass overridden version
// init completion
}
GameScene::UpdateScene( const float& timeDelta )
{
// general updating and game handling
UpdateLevel( timeDelta ); // this was _meant_ to call the overridden version, it does not
}
</code></pre>
<p>EntryPoint.cpp:</p>
<pre><code>#include "GameScene.h"
int main()
{
//NewScene( TestLevel() );
NewScene( TutorialLevel() );
float deltaTime;
while (gameLoop)
{
deltaTime = SecondsSinceLastFrame(); // pseudo
UpdateScene( deltaTime );
}
}
</code></pre>
<p>So, I was following a pattern that worked with SceneInit() calling LevelInit(), which is overridden in the derived classes. If I use either derived class constructor in NewScene(), I get those LevelInit() results at runtime. I thought this would be safe to use this pattern with UpdateScene().</p>
<p>What I see is UpdateScene() called the GameScene::UpdateLevel(), even though it is clearly overridden in the subclasses, just like LevelInit() is.</p>
<p>My (wild) guess is, I <em>am</em> calling UpdateLevel() as if I had explicitly cast it as GameScene. :\</p>
<p>And maybe, this is because I store currentScene <em>as</em> GameScene? (but then, doesn't that defeat the purpose of having polymorphism?)</p>
<p>I am missing something about either storing currentScene, or calling UpdateLevel(). I've tried calling like this:</p>
<pre><code> GameScene *s = currentScene;
s->UpdateLevel();
</code></pre>
<p>after reading that, as a pointer, the virtual mechanism should be finding the most-derived version of the method. (but alas...)</p>
<p>I wish I could have found an example here or elsewhere, but my searches pointed out problems with virtual in constructors/deconstructors, or just not using the 'virtual' keyword, etc.</p>

Allowing routes with and without {culture} (.net core 2.2)
|
<p>UPDATE: I got it working - added the following to the routes:</p>
<p>[Route("{culture}/[action]")]</p>
<p>[Route("/[action]")]</p>
<p>Problem is now when I am on /da/about it won't add the /da/ to the links generated on the AnchorTagHelper. </p>
<hr>
<p>Trying to allow culture in the routes. But I also want it to work without (fallback to english).</p>
<p>domain.com/en/about</p>
<p>domain.com/about</p>
<p>I can only get one of them to work at one time. Adding / removing the {culture} makes it work for each.</p>
<p>[Route("{culture}/about")]</p>
<p>Have tried changing, moving etc. everything with the MapRoutes</p>
<p>Any ideas how to catch both routes?</p>
<p>I have the following code:</p>
<pre><code>services.Configure<RouteOptions>(options =>
{
options.ConstraintMap.Add("culture", typeof(LanguageRouteConstraint));
});

sam local invoke gets connectionRefused when accessing S3 from localstack
|
<p>I'm running localstack where I create an s3 bucket. But when I invoke a lambda function with SAM to list the buckets, the connection is refused.</p>
<p>I start localstack with</p>
<pre><code>localstack start
</code></pre>
<p>then I create and list a bucket with a python script:</p>
<pre><code>import boto3
BUCKET_NAME = "mybucket"
HOST_ADDRESS= "http://localhost:4566"
s3_client = boto3.client('s3', region_name='us-east-1', endpoint_url=HOST_ADDRESS)
s3_client.create_bucket(Bucket=BUCKET_NAME)
</code></pre>
<p>Then I list the buckets with</p>
<pre><code>import boto3
s3_client = boto3.client('s3', endpoint_url="http://localhost:4566")
for bucket in s3_client.list_buckets()["Buckets"]:
print(bucket['Name'])
</code></pre>
<p>Now I invoke my lambda function that does the exact same thing with <code>sam build</code> and <code>sam local invoke --profile=localstack</code>. The profile localstack constains the credentials and region for my localstack.
The code is</p>

WPF circular progress bar: how to move hard coded property

<p>In my application i am using <code>Circular progress-bar</code>.
So in case i want to use this controller in several places how can i set the <code>Radius</code> property in my <code>XAML</code> instead of using the current value which is all the time 100 ? (in class <code>CircularProgressBar</code>)</p>

Smooth scroll anchor link requires unwanted double click
|
<p>Hey I'm trying to fix a tab inspired page for mobile. When the user clicks on a round circle it should ge to the text. Than when you click "Terug naar keuzemenu" you should go back to the circles (the navigation of the tabs). However when I want to go to other tabs the first time I click he doesnt scroll to the text section but the second time he does. So i have to click twice but cant figure out why.</p>

Eliminate Half Strings when receiving from Server socket Buffer in JAVA
|
<p>I have written a simple NIO Server and Inner-Client (Inside the same program)in a single program such that Server receives data from outside and the Inner-Client sends the data received by the server to out side Server. I am running both the processes continuously in two parallel threads using While() loops. Now the problem is, I will be receiving data at a very high speed to the Inside server and everything I receive, I will send them to the outer server using the Inside client. Some times, the retrieval of the data from the Buffer resulting in half the size of the total string. That means I am receiving "HELLO", but the total string is "HELLO SERVER". This is just an example. I will receive very long strings. Similarly, after sending the data to Outer-server through Inner client I will be listening for data and I am receiving the same half-strings.Is there any way I can eliminate these Half-strings and get the full-length string. I have to get the full string without any fail.</p>
<p>I am using while loops for the process. This is making the CPU utilization go high like 50%. Is there any way I can reduce the CPU utilization without using Thread.sleep method? Because I need to continuously listen to data from the Outer parties. They may send 2-4 strings for one single request. I tried using Executor service thread for running the processes continuously but it requires some sleep to be included. If I include some sleep I am not able to get the String and if I don't include the sleep my CPU-Utilization is going very high (50-60%). Can anyone help me with these two issues? </p>

<p>Running this causes the program to just crash. The exception is "Items collection must be empty".</p>
<p>From what I've read, this happens if you set the <code>Items</code> and <code>ItemsSource</code> are both set, but this isn't happening here.</p>

Why is my JSon giving me nulls on sub-arrays?
|
<p>I've been having a ghastly time trying to get an incoming Json message to serialize (and deserialize correctly). First is the incoming Json that I'm posting to our MVC rest service via POSTMAN. Validated it through JsonLint. The main problem is the two sub-arrays, accounts and propertyValues come through as null. serviceAddresses is an array member of the profilePush and its other properties are populating. Before I made them all into DataContracts, I was getting null value for serviceAddresses. What am I missing here?</p>

How to socket a asBroadcastStream so that it can be used in a stream builder?

<p>Hello i ran into a problem on Streams, specifically on how to use a broadcast stream for socket programming. Here is the code:</p>
<pre><code>import 'dart:async';

<p>I want to be able to expose the socket as a broadcastStream, I already tried using the asBroadcastStream function but I don't know how to pass it to another StreamBuilder. My plan is to be able to read status sent by the tcp server and update my AppBar title with StreamBuilder like so</p>
<pre><code>AppBar(title: StreamBuilder<Object>(
stream: widget.socket,
builder: (context, snapshot) {
return mycustomwidget();
}
)
</code></pre>
<p>As we know doing this is not possible cause the stream is not a broadcast stream and has already been listened by another streambuilder, I tried using asBroadCastStream like so</p>
<pre><code>class _MyHomePageState extends State<MyHomePage> {
final inputController = TextEditingController();
ScrollController scrollcontrol = ScrollController();
List<String> messageList = [];
Stream mystream=widget.socket.asBroadcastStream();
@override
void dispose() {
inputController.dispose();
widget.socket.destroy();
widget.socket.close();
super.dispose();
}
@override
Widget build(BuildContext context) {
mystream.listen((value)=>print(value));
return Scaffold(//...continuation
</code></pre>
<p>But obviously it comes back with a badState again. I'm still very new in handling streams like this I hope someone can clarify and fix my problem. Thank you!</p>

Get an X(std) value of efficient frontier from a given Y(mean) value with cvxopt?

<p>I'm trying to do portfolio optimization with cvxopt (Python), I'm able to get the efficient frontier with the following code, however, I'm not able to specify a Y value (mean or return) and get a corresponding X value (std or risk), if anyone has knowledge about this, I would be more than grateful if you can share it:</p>

No inverse error during encryption (node-rsa)

<p>I am trying to convert <a href="https://clover.app.box.com/s/rz18bni3bpmdrc8wc92xm4w8h9grrtty" rel="nofollow noreferrer">https://clover.app.box.com/s/rz18bni3bpmdrc8wc92xm4w8h9grrtty</a> from Java to node.js</p>
<p>I am using the node-rsa package and getting <code>error:0306E06C:bignum routines:BN_mod_inverse:no inverse</code> when trying to encrypt using an imported public key.</p>
<p>According to the clover example, I want to</p>
<ul>
<li>Parse the Base64 public key string (returned by the CDN). Obtain the modulus and exponent.</li>
<li>Generate an RSA public key using the modulus and exponent values.</li>
<li>Prepend the prefix value to the card number.</li>
<li>Using the public key, encrypt the combined prefix and card number.</li>
<li>Base64 encode the resulting encrypted data into a string.</li>
</ul>
<p>I was able to get the modulus and exponent, and it matches the result in Java:</p>

<p>However, I am getting the no inverse error mentioned above. It seems to be caused by the modulus. If I change it to something shorter, the error goes away.</p>

Logging across sub-modules – how to access parent logger name from sub-modules?
|
<p>I am trying to add logging to my python application that has several modules and submodules. Several sites say to create child loggers in modules. The advantage I see is that the child logger inheriting the parent logging config, it will provide consistency for the logging output (handlers, formatters, ...).</p>
<p>So far I am defining the <code>__main__</code> class logger name in each class and concatenate it with the current class’ name (<code>parentName.childName</code>) to get the module’s class loggers. It does not feel right, nor scalable. How could I improve this so I don’t have to hard code the <code>__main__</code> class logger name in each class? Here is what my code looks like:</p>
<p>Py file that I run:</p>
<pre><code>###app.py
import logging
from SubModule1 import *
class myApplication():
loggerName='myAPI'
def __init__(self, config_item_1=None,config_item_2=None,...config_item_N=None):
self.logger=self.logConfig()
self.logger.info("Starting my Application")
self.object1=mySubClass1(arg1, arg2, ... argM)
def logConfig(self):
fileLogFormat='%(asctime)s - %(levelname)s - %(message)s'
consoleLogFormat='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
# create logger
#logger = logging.getLogger(__name__)
logger = logging.getLogger(self.loggerName)
logger.setLevel(logging.DEBUG)
####CONSOLE HANDLER####
# create console handler and set level to debug
ch = logging.StreamHandler()
ch.setLevel(logging.INFO)
# create formatter
consoleFormatter = logging.Formatter(consoleLogFormat)
# add formatter to ch
ch.setFormatter(consoleFormatter)
# add ch to logger
logger.addHandler(ch)
####FILE HANDLER####
# create file handler and set level to debug
fh = logging.FileHandler('API_Log.txt')
fh.setLevel(logging.DEBUG)
# create formatter
fileFormatter = logging.Formatter(fileLogFormat)
# add formatter to ch
fh.setFormatter(fileFormatter)
# add ch to logger
logger.addHandler(fh)
logger.info('Logging is started!!')
return logger
def connect(self):
self.logger.info("Connecting to API")
self.object1.connect()
if __name__=="__main__":
config={"config_item_1": x,
"config_item_2": y,
...
"config_item_N": z
}
myApp=myApplication(config['config_item_1'],config['config_item_2'],...config['config_item_N'])
myApp.connect()
</code></pre>
<p>Module:</p>
<pre><code>###SubModule1.py
import logging
import app
class mySubClass1():
appRootLoggerName='myAPI'
def __init__(self,item1):
self.logger=logging.getLogger(self.appRootLoggerName + '.'+mySubClass1.__name__)
self.logger.debug("mySubClass1 object created - mySubClass1")
self.classObject1=item1
</code></pre>
<p>The line below is the one that is bothering me. What alternative to <code>self.appRootLoggerName + '.'+mySubClass1.__name__)</code> would keep the same logging configuration shared across my application’s modules/classes? </p>
<pre><code>logging.getLogger(self.appRootLoggerName + '.'+mySubClass1.__name__)
</code></pre>

Unknown error inserting in table in Python 3
|
<p>I'm trying to do a class to access a database in Sqlite3 in Python 3.
The database was created and when I check if its inserting on the database I get the following error on the second line of the <strong>init</strong> method:</p>
<pre><code>File "~/implementacao 2/Dabase_Connection.py", line 16, in __init__

c.execute('INSERT INTO '+ table_name + ' VALUES ( '+ data +' )')# Insert a row of data
sqlite3.OperationalError: near ",": syntax error
</code></pre>
<p>The code is this one:</p>
<pre><code>def __init__(self):
# self.create_database('database_name.db', 'table_name', 'id TEXT, data TEXT')
self.insert_in_database('database_name.db','table_name', '(\'111\',\'qqqq\')')

Avoid ConstraintViolationException in JPA and OneToMany relationship when merge
|
<p>What I want to achieve with the example below is to avoid the constraint violation exception that occurs
when run the following:</p>
<pre><code>Parent p = new Parent();
Set<Child> children = new HashSet<Child>();
Child c = new Child();
children.add(c);
p.setChildren(children);
entityManager.merge(p);
entityManager.merge(p);
</code></pre>
<p>How to configure JPA to achieve this effect? Below are the classes.</p>
<pre><code>@Entity
@Table(name = "parent", indexes = {uniqueConstraints = { @UniqueConstraint(columnNames = { "uri" }) })
public class Parent implements Serializable {
...
private String uri;

@Id
@Column(name = "id", unique = true)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "parent_seq")
@SequenceGenerator(name = "parent_seq", sequenceName = "parent_seq", allocationSize = 1)
public Long getId() {
return id;
}
@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
@JoinColumn(name = "parent_id")
public Set<Child> getChildren() {
return children;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Parent other = (Parent) obj;
if (uri == null) {
if (other.uri != null)
return false;
} else if (!uri.equals(other.uri))
return false;
return true;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((uri == null) ? 0 : uri.hashCode());
return result;
}
}
@Entity
@Table(name = "child", indexes = {uniqueConstraints = { @UniqueConstraint(columnNames = { "text" }) })
public class Child implements Serializable {
private String text;
@Id
@Column(name = "id", unique = true)

<p><strong>Question:</strong>
I wanted to revert back the record (<code>id=2</code>) to the version which was in <code>2019-08-15 06:42:10.661167</code> timestamp. That means, after the update, record #2 should have <code>x = 1</code> again.</p>
<p>I tried inserting with <code>ON DUPLICATE</code> as shown in below query,</p>
<pre><code>INSERT INTO t2 (id,x,y)
SELECT t.id,t.x,t.y
FROM t2 t
FOR SYSTEM_TIME AS OF TIMESTAMP '2019-08-15 06:42:10.661167'
WHERE t.id=2
ON DUPLICATE KEY UPDATE x=t.x, y=t.y;
</code></pre>
<p>This gave me the error saying there is a syntax error.</p>
<pre><code>ERROR 1064 (42000): You have an error in your SQL syntax;
check the manual that corresponds to your MariaDB server version
for the right syntax to use near 'SYSTEM_TIME AS OF TIMESTAMP '2019-08-15 06:42:10.661167' WHERE t.id=2 ON DUPLICA' at line 1
</code></pre>
<p>According to the error, it seems MariaDB does not identify <code>FOR</code> clause in select inserts.</p>
<p>Any other way to revert back to the other version using a query.</p>

Equality comparison not working in bash script despite echo showing variables are equal
|
<p>I need to determine that one value set locally in the script matches either one of two values stored on a git repo in a .txt file. I successfully retrieve these values and save them into variables <code>currentVersion</code> and <code>newVersion</code>. I also do this with <code>dispGitTime</code> and <code>gitMESSAGE</code>.</p>
<p>What's weird is that these two comparisons are working as expected:</p>
<pre><code>if [ "$dispGitTime" = "" ]; then dispGitTime=0; fi
if [ ! "$gitMESSAGE" = "" ]; then clear; echo "$gitMESSAGE"; sleep "$dispGitTime"; fi
</code></pre>
<p>But these two comparisons are not working! <code>else</code> is always being called!</p>
<pre><code>if [ "$currentVersion" = "$scriptVersion" ]; then
upToDate="true"
printf "\n%*s" $((COLS/2)) "This script is up-to-date!"; sleep 1

android: jsonArray parsing with Array.sort

<p>My Code works fine. But it is complicate...</p>
<p>I get my data via json</p>

<p>I controll the Nr. of finished Matches 126 is OK!</p>
<pre><code>Log.e("id", String.valueOf(i));

Cannot delete a row when the trigger is enabled
|
<p>Help Needed. i have a table and the respective audit table in emp schema.I was not able to delete the entry from the source table when the trigger is enabled.
The table is mapped to a trigger as stated below.</p>
<p>Below is the generic function , which i have used to audit across all the tables.</p>
<pre><code>Function:
============
CREATE OR REPLACE FUNCTION emp.fn_entry_audit()
RETURNS trigger
LANGUAGE plpgsql
AS $function$
declare
col_name text:='';
audit_table_name text := TG_TABLE_NAME || '_audit';
begin
if TG_OP = 'UPDATE' or TG_OP = 'INSERT' THEN
EXECUTE format('INSERT INTO emp.%1$I SELECT ($1).*,'''||TG_OP||'''',audit_table_name) using NEW;
else
EXECUTE format('INSERT INTO emp.%1$I SELECT ($1).*,'''||TG_OP||'''',audit_table_name) using old;
end if;
return new;
END $function$
Trigger creation
=================
create trigger trig_anish before insert or delete or update on emp.test_empname for each row execute procedure acaas.fn_entry_audit()
Table
======
create table emp.test_empname(id int4,fname varchar(300) not null,lname varchar(400),salary int4,last_modified_dt timestamp);
create table emp.test_empname_audit(id int4,fname varchar(300) not null,lname varchar(400),salary int4,last_modified_dt timestamp,modified_type varchar(10));
</code></pre>
<p>The difference between the two is modified_type column, which will mention whether the data is of insert, update or delete(TG_OP from above function).</p>
<p>now when i insert the values in emp.test_empname, it is getting inserted correctly in emp.test_empname_audit.</p>
<pre><code>select * from emp.test_empname;
emp.test_empname:
==================
id fname lname salary last_modified_dt
===============================================================
1 stacker pentacost 1000 04-04-18
2 lyri pav 2000 04-04-18
3 TEST TEST1 1000 04-04-18
select * from emp.test_empname_audit;
id fname lname salary last_modified_dt modified_type
===============================================================
1 stacker pentacost 1000 04-04-18 INSERT
2 lyri pav 1000 04-04-18 INSERT
2 lyri pav 2000 04-04-18 UPDATE
3 TEST TEST1 1000 04-04-18 Delete
</code></pre>
<p>Now, the issue is whenever I perform delete on source table (test_empname), the query is executing fine, but it shows 0 rows affected.
when i query in the table select * from test_empname where id=3, it still exists.But you can see the entry in audit as delete.</p>
<p>I disabled the trigger and performed delete function ,it executes fine and the row gets affected.How is the trigger affecting my delete functionality.Please help!!</p>

Libgdx how to create new objects of body to draw dynimcally

<p>I am trying to make a game where apples will fall from sky and allow boy to eat them
I had already made the environment and the boy and one apple falling correctly
but I want to make more objects of the apple to fall from sky at specific time

Query executing multiple times when using google social login with passport and sequelize
|
<p>Hi Guys this is my first question so please be patient, I'm having a problem using passport with sequelize, the problem happens after i search at the database for the record to check if the user already exists but when passport deserializes it, Sequelize executes five 'select queries', the code is similar to one i found in scotch.io i just attached sequelize api to it:</p>
<pre><code>module.exports = function (passport) {
// used to serialize the user for the session
passport.serializeUser(function (user, done) {
done(null, user.iduser);
});
// used to deserialize the user
passport.deserializeUser(function (id, done) {
userModel.findById(id)
.then(function (userVo) {
done(null, userVo);
}).catch(function(err) {
if(err)
throw err;
})
});
passport.use(new GoogleStrategy({
clientID: 'XXXXX',
clientSecret: 'XXXXXX',
callbackURL: 'XXXXX'
},
function (token, refreshToken, profile, done) {
// make the code asynchronous
// User.findOne won't fire until we have all our data back from Google
process.nextTick(function () {
// try to find the user based on their google id
sequelize.transaction(function (t) {
return sociaLoginModel.findOne({
where: {
idprovided: profile.id,
logintype: constants.GOOGLE_LOGIN_TYPE
}
}, {
transaction: t
})
.then(function (socialLoginResult) {
//if user was found, then retrieve and create a session for him returning the value to done
var socialLoginVo;
if (socialLoginResult) {
socialLoginVo = socialLoginResult.dataValues
return userModel.findById(socialLoginVo.tb11_fkuser, {
transaction: t
})
.then(function (userResult) {
return userResult.dataValues;
});
} else {
return individualsModel.create({
name: profile.displayName
}, {
transaction: t
})
.then(function (individualsResult) {
var individualsVo = individualsResult.dataValues
return userModel.create({
email: profile.emails[0].value,
user_type: constants.USER_INDIVIDUALS,
tb12_fkindividuals: individualsVo.idindividuals
}, {
transaction: t
})
.catch(function (err) {
if (err)
throw err;
})
.then(function (userResult) {
var userVo = userResult.dataValues
console.log(typeof profile.id)
return sociaLoginModel.create({
idprovided: profile.id,
token: token,
logintype: constants.GOOGLE_LOGIN_TYPE,
tb11_fkuser: userVo.iduser
}, {
transaction: t
})
.then(function (sociaLoginResult) {
return userVo
})
.catch(function(err) {
if(err)
throw err;
})
})
}).catch(function(err) {
if(err)
throw err
})
}
}).catch(function(err) {
if(err)
throw err
})
}).then(function (result) {
return done(null, result);
}).catch(function (err) {
if (err)
return done(err)
});
})
}))
};

<p>This code is in a file and i use it as a middleware in app.js calling:</p>
<pre><code>require('./logins/google')(passport);
</code></pre>
<p>I do that with local-login and facebook too, as almost the same code as in google login, why does Sequelize is executing that number of queries?? Am i doing something wrong?? How can i minimize that number? Thanks.</p>

POSIX shell function: printing arguments as a TSV record
|
<p>I'm writing a POSIX shell function that prints its arguments as a TSV record.
<br>
Each argument is escaped with the following rules:</p>
<ul>
<li><code>\n</code> for newline</li>
<li><code>\t</code> for tab</li>
<li><code>\r</code> for carriage return</li>
<li><code>\\</code> for backslash</li>
</ul>
<p>Here is the function:</p>
<pre class="lang-sh prettyprint-override"><code>#!/bin/sh
tsv_print() {
rec=
for str in "$@"
do
esc=
i=${#str}
until [ $i -eq 0 ]
do
end="${str#?}"
chr="${str%"$end"}"
case $chr in
"$__TAB__") chr='\t' ;;
"$__LF__") chr='\n' ;;
"$__CR__") chr='\r' ;;
\\) chr='\\' ;;
esac
esc="$esc$chr"
str="${end}"
i=$((i-1))
done
rec="$rec${rec:+"$__TAB__"}$esc"
done
# echo "$rec"
printf '%s\n' "$rec"
}
</code></pre>
<p>With the — <em>painful to read in code</em> — characters stored beforehand as follows:</p>
<pre><code>__TAB__=$(printf '\t')
__CR__=$(printf '\r')
__LF__="
"
</code></pre>
<hr />
<p>I would like to know:</p>
<ol>
<li><p><s>Why doesn't my code escape the characters at all?</s></p>
<p><sup><em><strong>edit:</strong></em> As @GordonDavisson pointed out, <code>echo</code> was the
culprit!! Using <code>printf</code> seems to be the only portable way, with the cost of a possible fork.</sup></p>
</li>
<li><p>Is there a better, POSIX compliant, method to do it? <code>awk</code> and <code>sed</code> don't seem appropriate for the job...</p>
</li>
<li><p>How would you do the un-escaping?</p>
<p><sup><em><strong>edit:</strong></em> As @KamilCuk posted in his <a href="https://stackoverflow.com/a/70049950/3387716">answer</a>, a <code>printf '%b'</code> would suffice; the TSV record has the correct format for that.</sup></p>
</li>
</ol>
<hr />
<h5>postscript</h5>
<p>In the end, the function wasn't needed because the input didn't contain any character to escape. That said, the input format wasn't that straight-forward to convert. It was a <a href="https://en.wikipedia.org/wiki/Self-defining_Text_Archive_and_Retrieval" rel="nofollow noreferrer">STAR File</a> with varying number of columns per line (limiting the lines to 80 characters max) and containing quoted strings...</p>
<p>input:</p>

using two data tables in a procedure SQL
|
<p>I was put in a situation where I was forced to create a procedure that uses two data tables such as this:</p>
<pre><code>ALTER PROCEDURE [sesuser].[Login_GetUserList]
(
@beginsWith NVARCHAR(20) = NULL,
@SortBy nvarchar(20) = NULL,
@sortByDirection nvarchar(5) = N'ASC'
)
AS
BEGIN
DECLARE @searchStr NVARCHAR(21)
IF @beginsWith IS NULL
SET @beginsWith = N''
ELSE
SET @beginsWith = dbo.SuperTrim(@beginsWith);
IF LEN(@beginsWith) > 0
SET @searchStr = @beginsWith + N'%'
ELSE
SET @searchStr = N'%'
DECLARE @sqlSTR NVARCHAR(4000)
DECLARE @sqlOffice NVARCHAR(100)
DECLARE @sqlOfficeID NVARCHAR(10)
DECLARE @sqlEndSTR NVARCHAR(4000)
SET @sqlSTR = N' SELECT
[SESLoginID] AS LoginID
,[SESSuspended] AS LoginSuspended
,[SESAdmin] AS Role_Admin
,[SESLoginID]
,[SESFirstName]
,[SESLastName]
,[SESEmail]
,[SESSuspended]
FROM sesuser.SESLogin
WHERE SESFirstName LIKE ''' + @searchStr + ''''
SET @sqlOfficeID = N' SELECT
[SESLoginID]
FROM sesuser.SESLogin
WHERE SESFirstName LIKE ''' + @searchStr + ''''
SET @sqlOffice = N' SELECT
[OfficeName]
FROM sesuser.Office
WHERE OfficeID LIKE ''' + @sqlOfficeID + ''''
SET @sqlEndSTR = @sqlSTR + @sqlOffice
PRINT @sqlEndSTR
EXEC sp_ExecuteSQL @sqlEndSTR
END
</code></pre>
<p>so as I understand it, this code supposed to in a table of office IDs and equivalent Office Name to replace the office ID with a Name in the other table and return it.</p>
<p>I then use the retrieve data string in a method in my c# code:</p>
<pre><code>public static DataTable GetUserList(string beginsWith, out string errMessage, string sortBy, string sortByDirection)
{
DataTable dt = null;
int errNum = 0;
string sql = "[sesuser].[Login_GetUserList]";
SqlDataAdapter adap = null;
SqlParameter param = null;
errMessage = "";
SqlConnection conn = Functions.Database.DBConnect(out errNum);
try
{
SqlCommand cmd = new SqlCommand(sql);
cmd.Connection = conn;
cmd.CommandType = CommandType.StoredProcedure;
param = new SqlParameter("@beginsWith", SqlDbType.NVarChar, 40);
param.Value = string.IsNullOrEmpty(beginsWith) ? "" : beginsWith.Trim();
cmd.Parameters.Add(param);
cmd.Parameters.AddWithValue("@SortBy", sortBy);
cmd.Parameters.AddWithValue("@sortByDirection", sortByDirection);
adap = new SqlDataAdapter(cmd);
dt = new DataTable();
adap.Fill(dt);
}
catch (Exception ex)
{
errMessage = ex.Message;
}
finally
{
Functions.Database.DBClose(conn);
}
return dt;
}
</code></pre>
<p>and later in my asp.net code I call back office name</p>
<pre><code><asp:BoundField DataField="OfficeName" HeaderText="Business Unit" ReadOnly="True" />
</code></pre>
<p>The problem is, it errors, saying that it cant find <code>OfficeName</code>.</p>
<p>Is there something I forgot? Or am I doing it wrong?</p>

Why can't I get touch input (Unity with C#) to work?
|
<p>I'm trying to finish the Android game I've been working on. I first made to controlling mechanism using mouse, but as it needs to work with multitouch for the shot button and the aiming area, I tried converting the script to touch input according to tutorials but it doesn't seem to register any touch.</p>
<p>Also, I wanted the script to record whether one of the touches, regardless of order, was placed on the area for either shot or aiming control when it begun, and place that in a Vector3 list. When respectable touch is lifted, it resets the value in that list index. Then, for example, the shooting script checks whether one of the list values is within the range of the shooting button radius, so it activates the weapon loading. It keeps telling me this error: </p>
<blockquote>
<p>ArgumentOutOfRangeException: Index was out of range. Must be
non-negative and less than the size of the collection. Parameter name:
index</p>

Bug in JavaFX by binding with middle man onto slider value property?
|
<p>I stumbled upon a problem using a slider in JavaFX.<br>
I create a fxml-file with a <em>Slider</em> and add a controller to it.<br>
Inside the controller I have a <em>DoubleProperty</em>, which binds to the <em>Slider</em>'s <em>valueProperty</em>. Then, when I want to bind to this property from somewhere else, I bind to the property, which is inside the controller (some kind of a middle-man approach see Figure).<br>
<a href="https://i.stack.imgur.com/cQ7Dq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cQ7Dq.png" alt="enter image description here"></a><br>
But when I do so, it does not work properly. </p>
<p>When I use the slider, the values get updated accordingly for a while, but when I wiggle it around, at some point it seems to stop updating the binding and refuses to do so again even after releasing and pressing it again.<br>
When I delete the middle-man property in the controller and just pipe through the <em>valueProperty</em> from the slider directly, it is working. </p>

Call to a member function get() when calling a doctrine 2 entity form the service locator

<p>I am new to Doctrine 2 and ZF2.</p>
<p><strong>My problem:</strong> I go to the route <code>myPage/bnk</code> that instantiates the class <code>BnkController</code> and the method <code>indexAction</code> if I try to access the <code>getEntityManager</code> method <strong>from there it all works</strong>. </p>

Parsing specific region of a txt, comparing to list of strings, then generating new list composed of matches
|
<p>I am trying to do the following:</p>
<ol>
<li>Read through a specific portion of a text file (there is a known starting point and ending point)</li>
<li>While reading through these lines, check to see if a word matches a word that I have included in a list </li>

C++ Structure declaration and usage to hold IP + Connections
|
<p>Good day to all, i am having a massive confusion declaring and using my structure to hold <strong>[IP] - [Connections]</strong> record.
I am trying to insert the IP address that is connecting into the structure, and his connection number <strong>#</strong>, for example if <strong>IP 123.123.12</strong> connects 2 (two) times, then update the <strong>[Connections]</strong> number in the struct for that <strong>IP (123.123.12)</strong>.</p>
<p>I have the following code, wich should work:</p>
<pre><code>// the struct
typedef struct {
int id; // is this usefull anyway ?
char *ip;
int connNumbers;
}test_sock;
// init struct
test_sock holder[5000];
int len = 0;
// the function
void AddtoStruct(char *ip)
{
if (len == 0) //if empty, insert.
{
len++;
holder->id = len;
holder->ip = ip;
holder->connNumbers = 1; //1 conexiune
return;
}
for (int i = 0; i<len; i++)
{
if (test_sock->id != 0) //check if its the same id !?
{
//Exista deja in structura , doar increase connNumbers;
if (strcmp(ip, holder->ip) == 0)
{
holder++;
holder->connNumbers++;
holder->id = antiddos_len;
holder->ip = ip;
return; // should return or not ?!
}
else{ //new IP, insert into struct.
len++; // COUNT AGAIN ?
holder->id = len;
holder->ip = ip;
holder->connNumbers = 1; // 1 connection
return; // should return or not ?!
}
}
}
}
</code></pre>
<p>Ok so what it should is:
Check the new incoming <strong>IP</strong> if it`s <strong>ALLREADY</strong> in the structure, then increase the number of connections for that ip
If the new incoming <strong>IP</strong> is <strong>NOT</strong> inside the structure, insert it, and if he connects again, of course increase the number of connections.</p>
<p>I compiled a minimal example below, wich you can run without problems on a Windows machine, using Visual Studio (i used 2013).</p>
<pre><code>#include "stdafx.h"
#include <iostream>
#include <Windows.h>
using namespace std;
// the struct
typedef struct {
int id; // is this usefull anyway ?
char *ip;
int connNumbers;
}test_sock;
// init struct
test_sock holder[5000];
int len = 0;
// the function
void AddtoStruct(char *ip)
{
if (len == 0) //if the struct is empty, insert.
{
len++;
holder->id = len;
holder->ip = ip;
holder->connNumbers = 1; //1 conexiune
cout << "ADDED NEW IP: " << holder->ip << " Connections: " << holder->connNumbers << endl;
cout << "-----------------------------------------------------------" << endl;
return;
}
for (int i = 0; i <= len; i++)
{
if (holder->id != 0) //verificam ca sa nu fie ACELASI ID
{
//Exista deja in structura , doar increase connNumbers;
if (strcmp(ip, holder->ip) == 0)
{
len++;
holder->connNumbers++;
holder->id = len;
holder->ip = ip;
cout << "NEW CONNECTION FROM IP: " << holder->ip << " Connections: " << holder->connNumbers << endl;
cout << "-----------------------------------------------------------" << endl;
}
else{ //new IP, insert into struct.
len++; // COUNT AGAIN ?
holder->id = len;
holder->ip = ip;
holder->connNumbers = 1; // 1 connection
cout << "CONNECTION FROM NEW IP: " << holder->ip << " Connections: " << holder->connNumbers << endl;
cout << "-----------------------------------------------------------" << endl;
return; // should return or not ?!
}
}
}
}
// use the function
int main() {
char *ip = "127.0.0.1";
char *ip2 = "127.0.0.3";
AddtoStruct(ip);
Sleep(5); // wait for new IP
AddtoStruct(ip2);
Sleep(5); // wait for SAME IP
AddtoStruct(ip);
system("pause");
}
</code></pre>
<p>As you can see, if you run the code, it does not work as it should, it count the same number of connections for every new IP ...
So please give me advice, or a fix, or anything, because i really need this, and it`s been 3 days of testing, without any progress.
Many thanks!</p>

<p>I tried to push them into arrayList named <code>"totalList=[];"</code> but it is pushing the same object repeatedly so:(See Array1 and array2 are same though their data from form is different)</p>
<p><a href="https://i.stack.imgur.com/MZ1sA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MZ1sA.png" alt="enter image description here"></a></p>
<p>How can i make this arrayList so dynamic which just push the current object rather than the old object? I am not able to push the newly created object into the arrayList.How can i change my arraylist?</p>

Bootstrap JavaScript adding events dynamically not linking to modal window
|
<p>I have a filter, where they select a media item (ie: radio, digital streetpole, traditional streetpole, bench, poster, etc.) and it then adds that with a whole bunch of it's variables. Let me expand:</p>
<p>The user has preset areas that they selected earlier but is also able to select multiple areas (Johannesburg, CapeTown, California, India) on top of that, then he selects a media item and it goes and looks for the average price of that media item in that area.</p>
<p>There are going to be more options now, on a modal window, that will allow them to select certain options about that media type in that area. </p>
<p>The thing leading to my issue: There are preset modal windows with options inside of them, depending on which 'more options' button they click on (so which media type), it must pop up the relevant modal window.</p>
<p><strong>MY ISSUE</strong></p>
<p>When adding a new media item, the modal window for extra options does not pop up anymore but does on the ones that were already there (ie: the preset ones).</p>
<p>Here are some pictures to show you what I mean:</p>
<p>Preset media items:</p>
<p><img src="https://i.stack.imgur.com/aFcRW.png" alt="initial preset media items"></p>
<p>modal window on one of the selected more options buttons:</p>
<p><img src="https://i.stack.imgur.com/ZGHrq.png" alt="modal window on one of the selected more options buttons"></p>
<p>adding media type / filtering:</p>
<p><img src="https://i.stack.imgur.com/cy7yC.png" alt="adding media type / filtering"></p>
<p>adds extra media item / filtering:</p>
<p><img src="https://i.stack.imgur.com/f5IIf.png" alt="adds extra media item / filtering"></p>
<p>So as you can see, the media item adds to the list, but selecting the 'more options' button, nothing happend on the new item, but it will still work on the old ones.</p>
<p>Here is the code:</p>
<p>HTML for Modal Popup:</p>

tdMoreSelect.innerHTML = '<center><input id="asset_'+assetNumber+'" class="check_asset_'+assetNumber+'" type="checkbox" name="checks[]"></center>';
</code></pre>
<p>Please also take note that the <code>type2</code> variable does put out the correct media type which is a lowercase, spaceless and bracketless string ie: <code>bus (Digital)</code> would be <code>busdigital</code>.</p>

XNA DrawPrimitives unintended line to 0,0
|
<p>I'm trying to learn XNA.
I'm currently drawing a figure on the screen where the user clicks.
I use an indexbuffer and PrimitiveType.LineList.
It works fine, however occasionally a line is drawn between a figure's first vertex and what seems like position 0,0. Why is it doing that?</p>

Proper Use of MYSQL UPDATE Function
|
<p>I am using MySQL query to UPDATE the information in the database.</p>
<p>I tried updating the information from the localhost/phpmyadmin and later on copy the code that was given in the localhost/phpmyadmin.</p>
<p>The problem is that the information/values are not updating in the database.</p>
<p>Below is the code:</p>
<pre><code><?php
if(isset($_POST['updateProfile']))
{
$newUser = $_POST['newUsername'];
$newPass = $_POST['newPassword'];
$newConNum = $_POST['newContactNumber'];
$newAdd = $_POST['newAddress'];
include("dbconnect.php");
//avatarPATH
$filepath = "avatar/owner-".$_SESSION['username']."-fname-".$_SESSION['fname']."-l_name-".$_SESSION['lname']."-filename-".$_FILES["file"]["name"];
$checkQuery = "SELECT * FROM `users`.`info` WHERE username = '".$userName."' ";
$checkResult = $con->query($checkQuery);
$count = mysqli_num_rows($checkResult);
while ($rows = mysqli_fetch_array($checkResult, MYSQLI_ASSOC))

FlatList: "Tried to get frame for out of range index NaN" with useEffect + fetch
|
<p>I'm trying to render a FlatList with data coming from fetch. It worked before, but now it gives me the error ""Tried to get frame for out of range index NaN". I have an async function which await the fetch but my return (render) with FlatList is being called first. I've changed the fetch code to use <code>useCallback(async() => ....) </code> but it doesn't work. I can't put the fetch inside the useEffect because I need it elsewhere inside the component (refresh stuff). Here is my Component code:</p>
<pre><code>function Home() {
const [data, setData] = useState({});
const getDataFromApi = useCallback(async() => {
const u = await SecureStore.getItemAsync('user');
const p = await SecureStore.getItemAsync('password');
await fetch('https://arko.digital/wp-json/wp/v2/arko_alerta', {
method: 'GET',
headers: {
'Authorization': 'Basic ' + Buffer.from(u + ':' + p).toString('base64'),
}})
.then((response) => response.json())
.then((json) => {
setData(json)
})
.catch((error) => {
console.error(error);
});
}, []);
useEffect(() => {
getDataFromApi();
}, []);
return (
<View style={{flex: 1}}>
<FlatList
data={data}
refreshing={refreshing}
onRefresh={onRefresh}
keyExtractor={({ id }, index) => id}
ListHeaderComponent={<Text style={commonStyles.bigHeader}>Alertas</Text>}
renderItem={({ item }) => (
<Alerta
title={item.content.rendered.split('</b>')}
content={item.content.rendered}
time={item.date}
excerpt={item.excerpt.rendered}
hidden={true}
/>
)}
/>
</View>
);
}
export default Home;
</code></pre>
<p>Using console.log i've noticed that the fetch INDEED return an array of objects in a couple of seconds. The problem is that my FlatList is not awaiting the fetch call. What am I doing wrong?
I'm a newbie</p>
<p>As I said, this worked before with a simple <code> async function getDataFromApi(){ ... }</code> outside useEffect and <code>getDataFromApi()</code> call inside useEffect.</p>
<p>Thanks in advance</p>

firebase_messaging fails to build for iOS but works for Android
|
<p>I'm looking to add the <code>firebase_messaging 7.0.3</code> package to add Push Notifications to my project. I've configured it for Android and it's working like a charm. Getting the Registration Token and can push notifications to my emulator and phone no problem.</p>
<p>Now, when I run the iOS build it fails on finding protocol declaration for 'FIRMessagingDelegate'. From what I understand the <code>FIR-</code> prefix has been removed some time ago and should now just be called MessagingDelegate.</p>
<p>I've ran both pod install and update and tried cleaning flutter.</p>
<pre><code>flutter clean
pod install
pod update
</code></pre>
<p>Also, tried to add <code>Firebase-Messaging</code> to my Podfile version less and trying older versions to no avail.</p>
<p>I followed all the steps in the iOS configuration at: <a href="https://pub.dev/packages/firebase_messaging" rel="nofollow noreferrer">https://pub.dev/packages/firebase_messaging</a> and tried it with method swizzling and without. I've ran out of options to try, perhaps some dependencies are not using the right version of firebase someplace but I'm not really sure how to check for those.</p>
<p>Here's the Stack Trace from the build:</p>
<pre><code>Launching lib/main.dart on iPhone 12 Pro Max in debug mode...

Does the transform function in plyr change variable names?
|
<p>The data set I am working with has two and three-word variable names with space in between. </p>
<pre><code>> names(final.data1)
## [1] "Vehicle ID" "Frame ID" "Total Frames"
## [4] "Global Time" "Local X" "Local Y"
## [7] "Global X" "Global Y" "Vehicle Length"
## [10] "Vehicle width" "Vehicle class" "Vehicle velocity"
## [13] "Vehicle acceleration" "Lane" "Preceding Vehicle ID"
## [16] "Following Vehicle ID" "Spacing" "Headway"
## [19] "svel" "sacc" "PrecVehClass"
</code></pre>
<p>I didn't change the names and kept doing analyses as is. When I used <code>transform</code> of <code>plyr</code> package, I got 2 columns for some of the variables which contained same numbers but had different names. </p>
<pre><code># Determining when the lane change occured
final.data1 <- ddply(final.data1, c("`Vehicle class`", "`Vehicle ID`"), transform,
lane.change = c(NA, ifelse(diff(Lane) != 0, "yes", ".")))
ordr <- with(final.data1, order(`Vehicle ID`))
final.data1 <- final.data1[ordr, ] #sort in ascending order by vehicle ID
names(final.data1)
## [1] "Vehicle class" "Vehicle ID" "Vehicle.ID"
## [4] "Frame.ID" "Total.Frames" "Global.Time"
## [7] "Local.X" "Local.Y" "Global.X"
## [10] "Global.Y" "Vehicle.Length" "Vehicle.width"
## [13] "Vehicle.class" "Vehicle.velocity" "Vehicle.acceleration"
## [16] "Lane" "Preceding.Vehicle.ID" "Following.Vehicle.ID"
## [19] "Spacing" "Headway" "svel"
## [22] "sacc" "PrecVehClass" "lane.change"
</code></pre>
<p>See <code>Vehicle ID</code> and <code>Vehicle.ID</code>? Why is this happening and how can I prevent this if I don't want to change original variable names?</p>

inject all services in startup.cs, .net core, overloaded
|
<p>This is more a general question.</p>
<p>But I have a question about injecting services in the startup.cs:</p>
<pre><code>public void ConfigureServices(IServiceCollection services)
{
services.AddControllers(opt =>
{
var policy = new AuthorizationPolicyBuilder().RequireAuthenticatedUser().Build();
opt.Filters.Add(new AuthorizeFilter(policy));
})
.AddFluentValidation(config =>
{
config.RegisterValidatorsFromAssemblyContaining<Create>();
});
services.AddApplicationServices(Configuration);
services.AddIdentityServices(Configuration);
}
</code></pre>
<p>So anyway I split the services in other file:</p>
<pre><code>public static class StartupExtensionClass
{
public static IServiceCollection AddApplicationServices(this IServiceCollection services,
IConfiguration Configuration)
{
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "API", Version = "v1" });
});
services.AddDbContext<DataContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddCors(opt =>
{
opt.AddPolicy("CorsPolicy", policy =>
{
policy.AllowAnyMethod().AllowAnyHeader().WithOrigins("http://localhost:3000");
});
});
services.AddMediatR(typeof(List.Handler).Assembly);
services.AddAutoMapper(typeof(MappingProfiles).Assembly);
services.AddScoped<IUserAccessor, UserAccessor >();
services.AddScoped<IPhotoAccessor, PhotoAccessor>();
services.Configure<CloudinarySettings>(Configuration.GetSection("Cloudinary"));
return services;
}
</code></pre>
<p>But for example if you have hundreds of services. IS that not overloading the application in the start phase?</p>
<p>Because all the services will initialized in the beginning.</p>
<p>Is there not a way just to initialise some services when they will directly been called.</p>
<p>Like lazy loading</p>
<p>Thank you</p>

<p>Despite not getting any errors importing the variation_feature.txt some essential indexes are not working.

<p>myisamchk is fixing the indexes without error, but the index "variation_idx" won't work.</p>
<p>DROPping and re-CREATing the one index runs without error, but the index won't work.</p>
<p>The other indexes are OK.</p>
<p>In another genome of this database (ensembl homo_sapiens_variation_106_38 - slightly bigger) from here: <a href="ftp://ftp.ensembl.org/pub/release-106/mysql/homo_sapiens_variation_106_38/" rel="nofollow noreferrer">ftp://ftp.ensembl.org/pub/release-106/mysql/homo_sapiens_variation_106_38/</a> I have the same problem (on another computer but with the same program installations).
With one difference: there is also the PRIMARY KEY (variation_feature_id) not working.</p>
<p>myisamchk is also running without error, but to no avail.</p>
<p>mysqlcheck (version 10.6 running very slow compared to 10.5) returns on the first computer then:</p>

<p>Now, this we know, but no repair tool can really repair or give a hint, what's wrong.</p>
<p>I've CREATEd an index on variation_name: it's working.</p>
<p>My changes to mariadb.cnf to adapt to the huge databases and the mysql versions of ensembl:</p>
<pre><code>[mysqld]

## ensembl has mysql version 5.6
## because of table creation scripts I need compatibility:

performance_schema
## ensembl writes in DATETIME fields: "0000-00-00 00:00:00"

## ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

stuck on cubit changing state to 2 widgets

<p>I have my base code working for cubit to update a simple counter in a class that is in a row on my app listview.</p>
<p>I want to update the counter of total items using bottomNavigationBar and a totalbagel field which is in a different class that my cubit. I wrapped my navbar text field totalbabgel in a block see below.</p>
<p>My issue is i do not know how to call in the cubit field in my bottom nav bar variable.</p>
<p>What is the correct format to reference a state variable from my cubit class?? All the online examples show only cubit state within same class text update. I need update state in 2 widgets.</p>

Method to touch MapControl XAML to set route
|
<p>I implemented a WPF MapControl control in my Winform application.</p>
<p>(Basically, add a WPF User Control project to your Winform solution. Drag and drop whatever WPF control. I chose a DevExpress WPF MapControl, but Microsoft's variant or any other control works just as nicely. Build the project once, and then drag and drop the control which then appears onto your Winform project. If you wish to set/get any properties or expose any methods, you would go to the associated C# code behind and make that public.)</p>
<p>Problem:
I want to create a method, which would have two GeoPoint arguments (longitude / latitude pairs). The method would then show the best route using BingMaps or the OpenMapDocs to show the route from point A to B, think Google Maps. I would call this method from a button or link on the Winform side.</p>
<p>Now, I understand crystal clear how to implement the transition and method. Been there, done that, so to speak. I have the two GeoPoint longitude/latitude pairs inside the code behind for the control.</p>
<p>My problem is how to handle the XAML side. I am not that familiar with WPF yet and the XAML side.</p>
<p>DevExpress said:</p>
<blockquote>
<p>It is necessary to configure the route data service inside the XAML user control.</p>
</blockquote>
<p>That was not the most helpful.</p>
<p>Any ideas?</p>
<p>I am using .Net 4.5.</p>
<p>Here is the XAML code for the DevExpress MapControl. The question is identical to the Microsoft MapControl. Both codes share very similar XAML, at least from my visual looking at it.</p>

Getting undefined array key when passing data with XMLHttpRequest
|
<p>I'm trying to pass a long formatted text string to a php process to save to a file. I am use the POST method as the string can be quite long. It seems to run thro the process and gives back the message 'File saved' but with the error message 'Undefined Array Key "data"' on line 2 of the php code. The file does not get saved and no data is being sent across from the XMLHttpRequest in the previous function.
My code is:- This gets 'str' from the previous function and is formatted correctly.</p>
<pre><code>function getGame(str){
//Sends data to the php process "saveGame.php".
var data = str;
var xhr = new XMLHttpRequest();
xhr.open("POST", "saveGame.php", true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() {
if (this.readyState === 4 ){
alert(xhr.responseText);
}
};
xhr.send(data);
}
</code></pre>
<p>it then goes the the 'saveGame.php' where the problem occurs on line 2.</p>
<pre><code><?php
$outputString = $_POST["data"];
$DOCUMENT_ROOT = $_SERVER['DOCUMENT_ROOT'];
$fp = fopen("C:\\xampp\\htdocs\\BowlsClub\\GamesSaved\\test26.txt","w");
fwrite($fp, $outputString);
if (!$fp){
$message = "Error writing to file. Try again later!" ;
}else{
$message = "File saved!";
}
fclose($fp);
echo $message;
?>
</code></pre>
<p>I think my code of the process is okay but there is a problem with passing the "data" variable and I not sure what it is.</p>
<p>I tested the file saving process. I put a dummy string as a value of 'outputString' and it saved it. When I went back and used the current code the file was overwritten and was blank, indicating it had saved a blank string. So it seems no data is been passed to saveTeams.php although the saving of the file works.</p>
<p>I have got a reproducible example below. If you use it with the saveTeams.php file and a file to attempt to save the data to it should display the error I get in an alert drop down.</p>
<pre><code><!DOCTYPE html>
<head>
<title>Test program</title>
<script language="javascript">
function formatOutput() {
// lots of formatting goes on here
var formattedText = "This is a test"; //test data
getGame(formattedText);
}
function getGame(str){
//Sends data to the php process "save Game".
var data = str;
var xhr = new XMLHttpRequest();
xhr.open("POST", "saveGame.php", true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() {
if (this.readyState === 4 ){
alert(xhr.responseText);
}
};
xhr.send(data);
}
</script>
</head>
<body>
<table width="1000" align="center" border="0">
<br />
<tr>
<td width="500"align="center" colspan="3" <button onclick="formatOutput()"/>Click on me</td>
</tr>
</table>
</body>
</html>
</code></pre>
<p>Hope this okay. I'm a bit new to this.</p>

jquery plugin, tablesorter pager with multiple tables
|
<p>I'm trying to use the jQuery tablesorter plugin on multiple tables with asp.net/mvc3. I'm following this tutorial:
<a href="http://weblogs.asp.net/hajan/archive/2011/02/09/table-sorting-amp-pagination-with-jquery-in-asp-net-mvc.aspx" rel="nofollow">http://weblogs.asp.net/hajan/archive/2011/02/09/table-sorting-amp-pagination-with-jquery-in-asp-net-mvc.aspx</a></p>
<p>I have 2 different tables on my page. I'd like to have the ability to set the number of rows for each table using this plugin. One problem I have is the tables by default have the number of rows shown by the first table. Then I'm able to use the plugin on each table. So for example, below table 1, I have this:</p>
<pre><code><div id="pagerOwnerRequests">
<form>
<select id="selectOwnerRequests" class="pagesize">
@*<select id="selectOwnerRequests" class="pagesizeOwnerRequests">*@
<option selected="selected" value="0">0</option>
<option value="2">2</option>
<option value="10">10</option>
</select>
</form>
</div>
</code></pre>
<p>Below table 2, I have this:</p>
<pre><code><div id="pagerBoardRequests">
<form>
<select id="selectBoardRequests" class="pagesize">
<option selected="selected" value="1">1</option>
<option value="2">2</option>
<option value="10">10</option>
</select>
</form>
</div>
</code></pre>
<p>At the bottom of my .cshtml file for this page, I have this:</p>
<pre><code> $(document).ready(function () {
$("#tbOwnerRequests").tablesorter({
headers: {
6: {
sorter: false
}
}
}
).tablesorterPager({ container: $("#pagerOwnerRequests"), size: $(".pagesize option:selected").val() });
});
$(document).ready(function () {
$("#tbBoardRequests").tablesorter({
headers: {
7: {
sorter:false
}
}
}
).tablesorterPager({ container: $("#pagerBoardRequests"), size: $(".pagesize option:selected").val() });
});
</code></pre>
<p>So what happens when the page load is, because table 1's drop down list is set to 0, both table 1 and table 2 have 0 elements. then when I manually go in and change the drop down for table 1 or table 2, it updates properly. I'm not sure why. I just started using jQuery/html/css so sorry if the answer is obvious, but I can't seem to see it. TIA.</p>

Any ideas on how I can fix this? (I want to avoid using EAGER loading).</p>
<p>Do I need to setup some form of session management for transactions?</p>

With Ant, how do I create seperate jar files from one src directory?
|
<p>I have one source directory in which I am trying to create separate cod files since my resources (PNG files) are beyond the limit imposed by the RAPC compiler.</p>
<p>I am trying to create:</p>
<ol>
<li>.cod(s) for the source</li>
<li>.cod(s) for low res. resources</li>
<li>.cod(s) for hi res. resources</li>
</ol>
<p>Which I am successful in creating the following:</p>
<p>AppMeasurement_BlackBerry.cod</p>
<p>com_mch_coffeehouse-1.cod</p>
<p>com_mch_coffeehouse.cod</p>
<p>com_mch_coffeehouse.jad</p>
<p>com_mch_coffeehouse_resources_hires-1.cod</p>
<p>com_mch_coffeehouse_resources_hires-2.cod</p>
<p>com_mch_coffeehouse_resources_hires-3.cod</p>
<p>com_mch_coffeehouse_resources_hires-4.cod</p>
<p>com_mch_coffeehouse_resources_hires-5.cod</p>
<p>com_mch_coffeehouse_resources_hires-6.cod</p>
<p>com_mch_coffeehouse_resources_hires-7.cod</p>
<p>com_mch_coffeehouse_resources_hires.cod</p>

<p>com_mch_coffeehouse_resources_lowres-4.cod</p>
<p>com_mch_coffeehouse_resources_lowres.cod</p>
<p>common-1.cod</p>
<p>common.cod</p>
<p>However, the application does not start-up and from the event log on the device, I get that wonderful encrypted message:</p>

Can Excel Vba code be updated via an Excel Add In for multiple users
|
<p>I have an Excel workbook that contains lots of VBA code. The VBA Code consists of many Sub routines, Functions and User Forms. Over 200+ employees will be using this Workbook.</p>
<p>Currently my VBA code lives inside the distributed Excel Workbook. The problem I fear I will be faced with is updating each Workbooks VBA code if any update is ever needed.</p>
<p>Would it be best to write all my VBA code as part of an Add In, upload a new version of the Add In to a site and have employees download from there? If so, would I encounter any limitations or restrictions? Is such feature even possible? Is VB.Net a better solution?</p>
<p>I have created an XLAM file from my original Workbook File. The original Workbook file containa all my Sub Routines, Functions, and UserForms. I am encountering an error when calling the UserForm directly, even though I referenced the XLAM file that contains UserForm1. </p>
<p>The following scenarios are being ran from the distributed WorkBook copy. The WorkBook is referencing the XLAM file. </p>
<p><strong>Scenario1: Calling a UserForm from a Sub assigned to a shape</strong>
The following Sub returns a <code>Runtime Error 424 Object Required</code></p>
<pre><code>Sub RectangleRoundedCorners1_Click()
UserForm1.Show 'highlights this line on the error, XLAM reference houses UserForm1
End Sub
</code></pre>
<p><strong>Scenario2: Calling a Sub Procedure from a shape that calls the UserForm</strong>
This method doesn't return an error, why? Can we not reference UserForm Objects from a referenced Add In? </p>
<pre><code>Sub RectangleRoundedCorners1_Click()
showUserForm
End Sub
Sub showUserForm()
UserForm1.Show
End Sub

I cannot find my error and it repeats forever
|
<p>Below while-loop is meant to repeat forever (thus <code>i=0</code> never modified inside the loop). The loop has a <code>checkpoint</code> so every read line continues where it left off.</p>
<p>But the checkpoint is not working, any way to fix that? Okay, I am not modifying the i var (which is a big suggestion) unless it is done, so it repeats, resumes checkpoint, and writes data, repeat. BUT what I am trying to say is that the checkpoint is broken and the program will not end after it is done reading all of the file.</p>
<h3>Code</h3>
<pre><code>i = 0
while i == 0:
file1 = open('APPMAKE', 'r')
Lines = file1.readlines()
count = 0
checkpoint = 0
ccount = 1
modeset = 0
# Strips the newline character
for line in Lines:
count += 1
ccount += 1
modeset += 1
if ccount > checkpoint:
checkpoint += 1
if modeset > 2:
modeset == 1
if modeset == 1:
elfexecutable = line
if modeset == 2:
appname = line
checkpoint = count + 1
break
#writing data
file1.close()
file2 = open(appname + ".app", "a") # append mode
file2.write(elfexecutable + "\n")
file2.close()
</code></pre>
<p>I put this in the APPMAKE file to test:</p>
<pre><code>elf.elf
ap.app
elf.elf
ap.app
elf.elf
ap.app
elf.elf
ap.app
</code></pre>
<p>Oh, and I made a manual to use this Python script. This <em>might</em> help you understand it:</p>
<pre class="lang-text prettyprint-override"><code>APP MAKE INSTRUCTIONS
=====================
First, to generate app, create a APPMAKE file. Next, add repeated code scripts
that are like this:
[elf file to link to]
[app file name]
...
Then, you made a APPMAKE file! To make more configs, list more of the scripts above.
Remember yo replace the things in the []s! Also, you can make a app run more than
1 elf you can make more than 1 configuration for each file. Now, how do you
run a APPMAKE file? Well first go copy & paste (do this sentence if your project is
not a template) the elfexepreferences.sh file into the folder with the
APPMAKE file. (do this even if your project is a template -->) Now, edit the file
you just pasted and edit the part that looks like this:
elfexecute () {
[function to execute elf] $1
}
Edit the []s depending on what system your apps are running on. (the elf
exepreferences file needs to be in every dir with a APPMAKE file.) And, getting close
to finished, copy and paste the elfexecuter.sh to your programs's main dir if it is
not already there. Then, in the same dir as the elfexecuter.sh file, add a
appexecute file and add a list of the APP files. Now, wanna make an app? To
execute the APPMAKE file, copy and paste appmake.py to the same dir
as the programs if it is not already there. Execute it and your app is
compiled. NOTICE: appexecute conatins names of .app files! Add the extensions!
So, I obeyed with my manual and tested the first few steps and got this to repeat and write a ENDLESS amount of elf.elf to my app file! Can someone please help!
</code></pre>
<p>My new edit but it still does not work:</p>
<pre><code>checkpoint = 0
i = 5
while i == 5:
file1 = open('APPMAKE', 'r')
Lines = file1.readlines()
count = 0
