self.tableView.tableHeaderView = segmentedControl;
If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.
You had thead
in your selector, but there is no thead
in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr
class to the th
, not vice-versa (although your comment seems to contradict what you wrote up above).
$('tr th').each(function(index){ if($('tr td').eq(index).attr('class') != ''){ // get the class of the td var tdClass = $('tr td').eq(index).attr('class'); // add it to this th $(this).addClass(tdClass ); } });
Problems only surface when I am I trying to give the first loaded content an active state
Does this mean that you want to add a class to the first button?
$('.o-links').click(function(e) { // ... }).first().addClass('O_Nav_Current');
instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:
CSS:
.image-area { width: 100%; height: auto; display: none; } .image-area:first-of-type { display: block; }
JavaScript:
var $slides = $('.image-area'), $btns = $('a.o-links'); $btns.on('click', function (e) { var i = $btns.removeClass('O_Nav_Current').index(this); $(this).addClass('O_Nav_Current'); $slides.filter(':visible').fadeOut(1000, function () { $slides.eq(i).fadeIn(1000); }); e.preventDefault(); }).first().addClass('O_Nav_Current');
You can use Jquery's on method and listen for the scroll
event.
In your test, you are comparing the two TestParent
beans, not the single TestedChild
bean.
Also, Spring proxies your @Configuration
class so that when you call one of the @Bean
annotated methods, it caches the result and always returns the same object on future calls.
See here:
A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.
This can also occur when using the wrong import (for example when using autoimport). let's take the MatTimePickerModule as an example. This will give an error message that is similar to the one described in the question:
import { NgxMatTimepickerModule } from '@angular-material-components/datetime-picker/lib/timepicker.module';
This should instead be
import { NgxMatTimepickerModule } from '@angular-material-components/datetime-picker';
I had the same issue and the following seemed to have addressed the issue.
a) Updated to latest version 1.3.5 and re-enabled all the diagnosis settings.
I was still getting the messages
b) Added the vendor folder with the dependent libraries to the workspace
This seems to have solved the problem.
I was facing same problem when I installed JRE by Oracle and solved this problem after my research.
I moved the environment path
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
below H:\Program Files\Java\jdk-13.0.1\bin
Like this:
Path
H:\Program Files\Java\jdk-13.0.1\bin
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
OR
Path
%JAVA_HOME%
%JRE_HOME%
You need to add the package containing the executable pg_config.
A prior answer should have details you need: pg_config executable not found
CORS headers should be sent from the server. If you use PHP it will be like this:
header('Access-Control-Allow-Origin: your-host');
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Methods: your-methods like POST,GET');
header('Access-Control-Allow-Headers: content-type or other');
header('Content-Type: application/json');
I also have the same problem, and the solution is I didn't bind the event in my onClick. so when it renders for the first time and the data is more, which ends up calling the state setter again, which triggers React to call your function again and so on.
export default function Component(props) {
function clickEvent (event, variable){
console.log(variable);
}
return (
<div>
<IconButton
key="close"
aria-label="Close"
color="inherit"
onClick={e => clickEvent(e, 10)} // or you can call like this:onClick={() => clickEvent(10)}
>
</div>
)
}
With React16.x, if you want to invoke a callback function on state change using useState
hook, you can use the useEffect
hook attached to the state change.
import React, { useEffect } from 'react';
useEffect(() => {
props.getChildChange(name); // using camelCase for variable name is recommended.
}, [name]); // this will call getChildChange when ever name changes.
Countdown timer in one line
CountdownTimer(Duration(seconds: 5), Duration(seconds: 1)).listen((data){
})..onData((data){
print('data $data');
})..onDone((){
print('onDone.........');
});
in my case I just installed a new version of android studio on a new laptop and cloned the old repository where
buildToolsVersion "30.0.2"
at application level build.gradle.
I just upgraded to 30.0.3
which android studio recommended on its own and the problem went away
For others who have the same problem in IntelliJ:
upgrading to the latest IDE version should resolve the issue.
In my case going from 2018.1 -> 2018.3.3

If you're using scss for your styles you can use a mixin to help generate the code. Your styles will quickly get out of hand if you put all the properties every time.
This is a very simple example - really nothing more than a proof of concept, you can extend this with multiple properties and rules as needed.
@mixin mat-table-columns($columns)
{
.mat-column-
{
@each $colName, $props in $columns {
$width: map-get($props, 'width');
&#{$colName}
{
flex: $width;
min-width: $width;
@if map-has-key($props, 'color')
{
color: map-get($props, 'color');
}
}
}
}
}
Then in your component where your table is defined you just do this:
@include mat-table-columns((
orderid: (width: 6rem, color: gray),
date: (width: 9rem),
items: (width: 20rem)
));
This generates something like this:
.mat-column-orderid[_ngcontent-c15] {
flex: 6rem;
min-width: 6rem;
color: gray; }
.mat-column-date[_ngcontent-c15] {
flex: 9rem;
min-width: 9rem; }
In this version width
becomes flex: value; min-width: value
.
For your specific example you could add wrap: true
or something like that as a new parameter.
I used this code to fix the issue of displaying items in the horizontal list.
new Container(
height: 20,
child: Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemCount: array.length,
itemBuilder: (context, index){
return array[index];
},
),
],
),
);
When you call "https://darkorbit.com/" your server figures that it's missing "www" so it redirects the call to "http://www.darkorbit.com/" and then to "https://www.darkorbit.com/", your WebView call is blocked at the first redirection as it's a "http" call. You can call "https://www.darkorbit.com/" instead and it will solve the issue.
As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.
For example:
Assume we have double _bmi;
and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:
String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}
or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.
When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink]
, then it should be assigned a name of the property the value of which will be the route it should navigate the user to.
So to fix your issue, replace this routerLink="['/about']"
with routerLink="/about"
in your HTML.
There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:
<nav class="main-nav>
<ul
class="main-nav__list"
ng-sticky
addClass="main-sticky-link"
[ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/">Home</a>
</li>
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/about">About us</a>
</li>
</ul>
</nav>
It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>
, either in your template provided above or in a parent component.
There's another issue with your AppRoutingModule
. You need to export the RouterModule
from there so that it is available to your AppModule
when it imports it. To fix that, export it from your AppRoutingModule
by adding it to the exports
array.
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
{ path: 'about', component: AboutComponent },
{ path: 'what', component: WhatwedoComponent },
{ path: 'contacts', component: FooterComponent },
{ path: 'projects', component: ProjectsComponent},
];
@NgModule({
imports: [
CommonModule,
RouterModule.forRoot(routes),
],
exports: [RouterModule],
declarations: []
})
export class AppRoutingModule { }
You Can Wrap your widget with Flexible Widget and than you can set property of Text using overflow property of Text Widget. you have to set TextOverflow.clip for example:-
Flexible
(child: new Text("This is Dummy Long Text",
style: TextStyle(
fontFamily: "Roboto",
color: Colors.black,
fontSize: 10.0,
fontWeight: FontWeight.bold),
overflow: TextOverflow.clip,),)
hope this help someone :)
You can use this one and it's best practice.
SingleChildScrollView( child: Column( children: <Widget>[ //Your Widgets //Your Widgets, //Your Widgets ], ), );
You can use the container, It will help you to set the alignment.
Widget _buildListWidget({Map reminder}) {
return Container(
color: Colors.amber,
alignment: Alignment.centerLeft,
padding: EdgeInsets.all(20),
height: 80,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
alignment: Alignment.centerLeft,
child: Text(
reminder['title'],
textAlign: TextAlign.left,
style: TextStyle(
fontSize: 16,
color: Colors.black,
backgroundColor: Colors.blue,
fontWeight: FontWeight.normal,
),
),
),
Container(
alignment: Alignment.centerRight,
child: Text(
reminder['Date'],
textAlign: TextAlign.right,
style: TextStyle(
fontSize: 12,
color: Colors.grey,
backgroundColor: Colors.blue,
fontWeight: FontWeight.normal,
),
),
),
],
),
);
}
You control how a row or column aligns its children using the mainAxisAlignment and crossAxisAlignment properties. For a row, the main axis runs horizontally and the cross axis runs vertically. For a column, the main axis runs vertically and the cross axis runs horizontally.
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
The problem is in your pubspec.yaml
, here you need to delete the last comma.
uses-material-design: true,
Use npm update
or,
Run `npm install --save-dev @angular-devkit/build-angular
`
May be you are using wrong mysql_connector.
Use connector of same mysql version
npm install --save-dev @angular-devkit/build-angular@latest
solved it for me.
In Mysql Latest docker container
ALTER USER root IDENTIFIED WITH mysql_native_password BY 'password';
If you want to round corners with transparent background, the best approach is using ClipRRect.
return ClipRRect(
borderRadius: BorderRadius.circular(40.0),
child: Container(
height: 800.0,
width: double.infinity,
color: Colors.blue,
child: Center(
child: new Text("Hi modal sheet"),
),
),
);
Another way to go
const data: {[key: string]: any} = require('./data.json');
This was you still can define json type is you want and don't have to use wildcard.
For example, custom type json.
interface User {
firstName: string;
lastName: string;
birthday: Date;
}
const user: User = require('./user.json');
After doing lots of analysis for my Ubuntu 20.04 I have found the solution
for me the error was /home/rk/Android/Sdk/tools/bin/sdkmanager
was missing write permission.
chmod +w home/rk/Android/Sdk/tools/bin/sdkmanager
Then run the below command.
flutter doctor --android-licenses
it automatically process the licences.
You can use MediaQuery for parent's dimension or FractionallySizedBox as containers.
In my case it was the order of importing in index.js
/* /components/index.js */
import List from './list.vue';
import ListItem from './list-item.vue';
export {List, ListItem}
and if you use ListItem
component inside of List
component it will show this error as it is not correctly imported. Make sure that all dependency components are imported first in order.
Use
implementation 'com.android.support:appcompat-v7:27.1.1'
Don't use like
implementation 'com.android.support:appcompat-v7:27.+'
It may give you an error and don't use an older version than this.
or event don't do like this
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
etc... numbers of libraries and then
implementation 'com.android.support:appcompat-v7:27.+'
the same library but it has a different version, it can give you an error.
for Mac,
Click on Android Studio,
then go to Preferences...
Set your Path inside DART SDK PATH here.
After Enable this for your project(like image show),then apply
1.On Child Widget : add parameter Function paramter
class ChildWidget extends StatefulWidget {
final Function() notifyParent;
ChildWidget({Key key, @required this.notifyParent}) : super(key: key);
}
2.On Parent Widget : create a Function for the child to callback
refresh() {
setState(() {});
}
3.On Parent Widget : pass parentFunction to Child Widget
new ChildWidget( notifyParent: refresh );
4.On Child Widget : call the Parent Function
widget.notifyParent();
I was getting this from webpack lazy loading like this
import Loader from 'some-loader-component';
const WishlistPageComponent = loadable(() => import(/* webpackChunkName: 'WishlistPage' */'../components/WishlistView/WishlistPage'), {
fallback: Loader, // warning
});
render() {
return <WishlistPageComponent />;
}
// changed to this then it's suddenly fine
const WishlistPageComponent = loadable(() => import(/* webpackChunkName: 'WishlistPage' */'../components/WishlistView/WishlistPage'), {
fallback: '', // all good
});
I see you have all the settings right. You just need to end the local web server and start it again with
php artisan serve
Everytime you change your .env
file, you need tor restart the server for the new options to take effect.
Or clear and cache your configuration with
php artisan config:cache
Another option can be using built in angular formatDate function. I am assuming that you are using reactive forms. Here todoDate
is a date input field in template.
import {formatDate} from '@angular/common';
this.todoForm.controls.todoDate.setValue(formatDate(this.todo.targetDate, 'yyyy-MM-dd', 'en-US'));
Install Qt
sudo apt-get install build-essential
sudo apt-get install qtcreator
sudo apt-get install qt5-default
Install documentation and examples If Qt Creator is installed thanks to the Ubuntu Sofware Center or thanks to the synaptic package manager, documentation for Qt Creator is not installed. Hitting the F1 key will show you the following message : "No documentation available". This can easily be solved by installing the Qt documentation:
sudo apt-get install qt5-doc
sudo apt-get install qt5-doc-html qtbase5-doc-html
sudo apt-get install qtbase5-examples
Restart Qt Creator to make the documentation available.

This problem is commonly related to compiler errors in the Java code. Sometimes Android Studio does not show these errors in the Project explorer
. However, when a problematic .java
file is opened, errors are shown. Try to resolve errors and rebuild the project.
Do not use authorization instead of authentication. I should get whole access to service all clients with header. The working code is :
public class TokenAuthenticationHandler : AuthenticationHandler<TokenAuthenticationOptions>
{
public IServiceProvider ServiceProvider { get; set; }
public TokenAuthenticationHandler (IOptionsMonitor<TokenAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock, IServiceProvider serviceProvider)
: base (options, logger, encoder, clock)
{
ServiceProvider = serviceProvider;
}
protected override Task<AuthenticateResult> HandleAuthenticateAsync ()
{
var headers = Request.Headers;
var token = "X-Auth-Token".GetHeaderOrCookieValue (Request);
if (string.IsNullOrEmpty (token)) {
return Task.FromResult (AuthenticateResult.Fail ("Token is null"));
}
bool isValidToken = false; // check token here
if (!isValidToken) {
return Task.FromResult (AuthenticateResult.Fail ($"Balancer not authorize token : for token={token}"));
}
var claims = new [] { new Claim ("token", token) };
var identity = new ClaimsIdentity (claims, nameof (TokenAuthenticationHandler));
var ticket = new AuthenticationTicket (new ClaimsPrincipal (identity), this.Scheme.Name);
return Task.FromResult (AuthenticateResult.Success (ticket));
}
}
Startup.cs :
#region Authentication
services.AddAuthentication (o => {
o.DefaultScheme = SchemesNamesConst.TokenAuthenticationDefaultScheme;
})
.AddScheme<TokenAuthenticationOptions, TokenAuthenticationHandler> (SchemesNamesConst.TokenAuthenticationDefaultScheme, o => { });
#endregion
And mycontroller.cs
[Authorize(AuthenticationSchemes = SchemesNamesConst.TokenAuthenticationDefaultScheme)]
public class MainController : BaseController
{ ... }
I can't find TokenAuthenticationOptions now, but it was empty. I found the same class PhoneNumberAuthenticationOptions :
public class PhoneNumberAuthenticationOptions : AuthenticationSchemeOptions
{
public Regex PhoneMask { get; set; }// = new Regex("7\\d{10}");
}
You should define static class SchemesNamesConst
. Something like:
public static class SchemesNamesConst
{
public const string TokenAuthenticationDefaultScheme = "TokenAuthenticationScheme";
}
Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.
More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize
The snippets to save & load can be found below:
model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')
# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')
A sample output of this :
I had same issue. After browsing and struggling with issue found the below solution
import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';

As some people have mentioned before, this very well could be a simpler problem having to do with one java installation taking precedence over the other.
In my case it was java 8 being overshadowed by a default newer java.
I installed java 8:
sudo apt-get install openjdk-8-jdk
Then I updated the installed java to be the new default:
sudo update-alternatives --config java
Whereby I selected java 8's id number.
After doing these (pretty simple) steps, I could just run sdkmanager without error.
Hope this helps someone!
This fixed the problem by having it as the first two lines of the script:
!pip install opencv-python
!apt update && apt install -y libsm6 libxext6
!apt-get install -y libxrender-dev
You can use FutureBuilder widget instead. This takes an argument which must be a Future. Then you can use a snapshot which is the state at the time being of the async call when loging in, once it ends the state of the async function return will be updated and the future builder will rebuild itself so you can then ask for the new state.
FutureBuilder(
future: myFutureFunction(),
builder: (context, AsyncSnapshot<List<item>> snapshot) {
if (!snapshot.hasData) {
return Center(
child: CircularProgressIndicator(),
);
} else {
//Send the user to the next page.
},
);
Here you have an example on how to build a Future
Future<void> myFutureFunction() async{
await callToApi();}
let fs = require('fs');

fs.readFile('./markers.json', handleJSONFile);
var handleJSONFile = function (err, data) {

For me, I had ~6 different Nuget packages to update and when I selected Microsoft.AspNetCore.All first, I got the referenced error.
I started at the bottom and updated others first (EF Core, EF Design Tools, etc), then when the only one that was left was Microsoft.AspNetCore.All it worked fine.
The way I resolved this error was by finding and fixing the error that the console reported.
Run ng build
in your command line/terminal, and it should display a useful error, such as the example in red here: Property 'name' does not exist on type 'object'.
Action Definition
const selectSlice = () => {
return {
type: 'SELECT_SLICE'
}
};
Action Dispatch
store.dispatch({
type:'SELECT_SLICE'
});
Make sure the object structure of action defined is same as action dispatched. In my case, while dispatching action, type was not assigned to property type
.
I have tried some of the previous suggestions. It does update the table but I have some concerns:
dataSource.data
with its clone. e.g.this.dataSource.data = [...this.dataSource.data];
If the data is large, this will reallocate lot of memory. Moreover, MatTable thinks that everything is new inside the table, so it may cause performance issue. I found my table flickers where my table has about 300 rows.
paginator._changePageSize
. e.g.this.paginator._changePageSize(this.paginator.pageSize);
It will emit page
event. If you have already had some handling for the page
event. You may find it weird because the event may be fired more than once. And there can be a risk that if somehow the event will trigger _changePageSize()
indirectly, it will cause infinite loop...
I suggest another solution here. If your table is not relying on dataSource
's filter
field.
filter
field to trigger table refresh:this.dataSource.filter = ' '; // Note that it is a space, not empty string
By doing so, the table will perform filtering and thus updating the UI of the table. But it requires having your own dataSource.filterPredicate()
to handling your filtering logic.
Adding this maven dependency with JUnit Jupiter (v.5.5.1) solves the issue.

In my case, one of my closing parenthesis for "onChanges()" were missed on the input element and thus the input element was apparently not being rendered at all:

Another solution is below way and It was my fault that when happened I put HomeService
in declaration section in app.module.ts
whereas I should put HomeService
in Providers section that as you see below HomeService
in declaration:[]
is not in a correct place and HomeService
is in Providers :[]
section in a correct place that should be.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HomeComponent } from './components/home/home.component';
import { HomeService } from './components/home/home.service';
@NgModule({
declarations: [
AppComponent,
HomeComponent,
HomeService // You will get error here
],
imports: [
BrowserModule,
BrowserAnimationsModule,
AppRoutingModule
],
providers: [
HomeService // Right place to set HomeService
],
bootstrap: [AppComponent]
})
export class AppModule { }
hope this help you.
Laravel 419 post error is usually related with api.php and token authorization
Laravel automatically generates a CSRF "token" for each active user session managed by the application. This token is used to verify that the authenticated user is the one actually making the requests to the application.
Add this to your ajax call
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
or you can exclude some URIs in VerifyCSRF token middleware
protected $except = [
'/route_you_want_to_ignore',
'/route_group/*
];
Have you tried moving your [(ngModel)]
to the div
instead of the switch
in your HTML? I had the same error appear in my code and it was because I bound the model to a <mat-option>
instead of a <mat-select>
. Though I am not using form control.
Best way is to use below command
$ wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
$ unzip \platform-tools-latest-linux.zip
$ sudo cp platform-tools/adb /usr/bin/adb
$ sudo cp platform-tools/fastboot /usr/bin/fastboot
Now run adb version to verify it’s been updated.
Pim's answer is very helpful. In my case, I have to use
Expires / Max-Age: "Session"
If it is a dateTime, even it is not expired, it still won't send the cookie to the backend:
Expires / Max-Age: "Thu, 21 May 2020 09:00:34 GMT"
Hope it is helpful for future people who may meet same issue.
It should be like this.
In your Component
computed: {
...mapGetters({
nameFromStore: 'name'
}),
name: {
get(){
return this.nameFromStore
},
set(newName){
return newName
}
}
}
In your store
export const store = new Vuex.Store({
state:{
name : "Stackoverflow"
},
getters: {
name: (state) => {
return state.name;
}
}
}
After trying everything, including node/npm upgrade, cache cleaning and reverting code, nothing helped besides one simple thing: Turning OFF Windows 10's Real-time protection during the dev/build. Looks like latest updates made it super aggressive.
If you want to set only one specific class, you might write a TypeScript function returning a boolean to determine when the class should be appended.
TypeScript
function hideThumbnail():boolean{
if (/* Your criteria here */)
return true;
}
CSS:
.request-card-hidden {
display: none;
}
HTML:
<ion-note [class.request-card-hidden]="hideThumbnail()"></ion-note>
There is actually a default pattern that you can employ to achieve this result without having to implement IDesignTimeDbContextFactory
and do any config file copying.
It is detailed in this doc, which also discusses the other ways in which the framework will attempt to instantiate your DbContext
at design time.
Specifically, you leverage a new hook, in this case a static method of the form public static IWebHost BuildWebHost(string[] args)
. The documentation implies otherwise, but this method can live in whichever class houses your entry point (see src). Implementing this is part of the guidance in the 1.x to 2.x migration document and what's not completely obvious looking at the code is that the call to WebHost.CreateDefaultBuilder(args)
is, among other things, connecting your configuration in the default pattern that new projects start with. That's all you need to get the configuration to be used by the design time services like migrations.
Here's more detail on what's going on deep down in there:
While adding a migration, when the framework attempts to create your DbContext
, it first adds any IDesignTimeDbContextFactory
implementations it finds to a collection of factory methods that can be used to create your context, then it gets your configured services via the static hook discussed earlier and looks for any context types registered with a DbContextOptions
(which happens in your Startup.ConfigureServices
when you use AddDbContext
or AddDbContextPool
) and adds those factories. Finally, it looks through the assembly for any DbContext
derived classes and creates a factory method that just calls Activator.CreateInstance
as a final hail mary.
The order of precedence that the framework uses is the same as above. Thus, if you have IDesignTimeDbContextFactory
implemented, it will override the hook mentioned above. For most common scenarios though, you won't need IDesignTimeDbContextFactory
.
Here's a fairly simple way to achieve it by enclosing both the magnifying glass icon and the input field inside a div with relative positioning.
Absolute positioning is applied to the icon, which takes it out of the normal document layout flow. The icon is then positioned inside the input. Left padding is applied to the input so that the user's input appears to the right of the icon.
Note that this example places the magnifying glass icon on the left instead of the right. This is recommended when using <input type="search">
as Chrome adds an X button in the right side of the searchbox. If we placed the icon there it would overlay the X button and look fugly.
Here is the needed Bootstrap markup.
<div class="position-relative">
<i class="fa fa-search position-absolute"></i>
<input class="form-control" type="search">
</div>
...and a couple CSS classes for the things which I couldn't do with Bootstrap classes:
i {
font-size: 1rem;
color: #333;
top: .75rem;
left: .75rem
}
input {
padding-left: 2.5rem;
}
You may have to fiddle with the values for top, left, and padding-left.
If you want to reload the page , you can easily go to your component then do :
location.reload();
There is no need to use angular http, you can get with js native functions

Looks like different approaches for different version. I am using Flutter v1.17.1 and the below works for me.
onTap: () {
FocusScopeNode currentFocus = FocusScope.of(context);
if (!currentFocus.hasPrimaryFocus && currentFocus.focusedChild != null) {
currentFocus.focusedChild.unfocus();
}
}
//Component. home.ts :
contacts:IContacts[];
ionViewDidLoad() {
this.rest.getContacts()
.subscribe( res=> this.contacts= res as IContacts[]) ;
// reorderArray. accepts only Arrays
Reorder(indexes){
reorderArray(this.contacts, indexes)
}
// Service . res.ts
getContacts(): Observable<IContacts[]> {
return this.http.get<IContacts[]>(this.apiUrl+"?results=5")
And it works fine
I ran into this error while trying to click some element (or its overlay, I didn't care), and the other answers didn't work for me. I fixed it by using the elementFromPoint
DOM API to find the element that Selenium wanted me to click on instead:
element_i_care_about = something()
loc = element_i_care_about.location
element_to_click = driver.execute_script(
"return document.elementFromPoint(arguments[0], arguments[1]);",
loc['x'],
loc['y'])
element_to_click.click()
I've also had situations where an element was moving, for example because an element above it on the page was doing an animated expand or collapse. In that case, this Expected Condition class helped. You give it the elements that are animated, not the ones you want to click. This version only works for jQuery animations.
class elements_not_to_be_animated(object):
def __init__(self, locator):
self.locator = locator
def __call__(self, driver):
try:
elements = EC._find_elements(driver, self.locator)
# :animated is an artificial jQuery selector for things that are
# currently animated by jQuery.
return driver.execute_script(
'return !jQuery(arguments[0]).filter(":animated").length;',
elements)
except StaleElementReferenceException:
return False

I faced similar issue "CrashLoopBackOff" when I debugged getting pods and logs of pod. Found out that my command arguments are wrong
Replace a hard coded version to + example:

You can do it like that
Expanded(

You can make your own "lifecycle methods" using hooks for maximum nostalgia.
Utility functions:
import { useEffect, useRef } from "react";
export const useComponentDidMount = handler => {
return useEffect(() => {
return handler();
}, []);
};
export const useComponentDidUpdate = (handler, deps) => {
const isInitialMount = useRef(true);
useEffect(() => {
if (isInitialMount.current) {
isInitialMount.current = false;
return;
}
return handler();
}, deps);
};
Usage:
import { useComponentDidMount, useComponentDidUpdate } from "./utils";
export const MyComponent = ({ myProp }) => {
useComponentDidMount(() => {
console.log("Component did mount!");
});
useComponentDidUpdate(() => {
console.log("Component did update!");
});
useComponentDidUpdate(() => {
console.log("myProp did update!");
}, [myProp]);
};

I had the same problem with Angular CLI: 10.1.5 The code works fine, but the error was shown in the VScode v1.50
Resolved by killing the terminal (ng serve) and restarting VScode.
In my case only get
request works well according to MindingData's answer. For other types of request you need to write:
app.UseCors(corsPolicyBuilder =>
corsPolicyBuilder.WithOrigins("http://localhost:3000")
.AllowAnyMethod()
.AllowAnyHeader()
);
Don't forget to add .AllowAnyHeader()
You can use DecoratedBox
.
@override
Widget build(BuildContext context) {
return DecoratedBox(
decoration: BoxDecoration(
image: DecorationImage(image: AssetImage("your_asset"), fit: BoxFit.cover),
),
child: Center(child: FlutterLogo(size: 300)),
);
}
Output:
Yea, Indeed @Evert answer is perfectly correct. In addition I'll like to add one more reason that could encounter such error.
>>> np.array([np.zeros((20,200)),np.zeros((20,200)),np.zeros((20,200))])
This will be perfectly fine, However, This leads to error:
>>> np.array([np.zeros((20,200)),np.zeros((20,200)),np.zeros((20,201))])
ValueError: could not broadcast input array from shape (20,200) into shape (20)
The numpy arry within the list, must also be the same size.
Here's another way to force a type-cast even between incompatible types and interfaces where TS compiler normally complains:
export function forceCast<T>(input: any): T {
// ... do runtime checks here
// @ts-ignore <-- forces TS compiler to compile this as-is
return input;
}
Then you can use it to force cast objects to a certain type:
import { forceCast } from './forceCast';
const randomObject: any = {};
const typedObject = forceCast<IToDoDto>(randomObject);
Note that I left out the part you are supposed to do runtime checks before casting for the sake of reducing complexity. What I do in my project is compiling all my .d.ts
interface files into JSON schemas and using ajv
to validate in runtime.
Using dataType: 'jsonp'
worked for me.
async function get_ajax_data(){
var _reprojected_lat_lng = await $.ajax({
type: 'GET',
dataType: 'jsonp',
data: {},
url: _reprojection_url,
error: function (jqXHR, textStatus, errorThrown) {
console.log(jqXHR)
},
success: function (data) {
console.log(data);
// note: data is already json type, you
// just specify dataType: jsonp
return data;
}
});
} // function
I Had the same problem and finally reached to the solution.
add "--stacktrace --debug" to your command-line options(File -> Settings -> Compiler) then run it. This will show the problem(unwanted code) in your code.
you should return Scaffold widget and add your widget inside Scaffold
suck as this code :
import 'package:flutter/material.dart';
void main() {
runApp(new MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: Center(child: new Text("Hello, World!"));
);
}
}
I fixed this issue by steps :
turn off your network (wireless or wired...).
reboot your system.
before turning on your network on PC, execute command docker-compose up, it's going to create new network.
then you can turn network on and go on ...
I just experienced this issue while using the Windows Subsystem for Linux (WSL2), so I will also share this solution.
My objective was to render the output from webpack both at wsl:3000
and localhost:3000
, thereby creating an alternate local endpoint.
As you might expect, this initially caused the "Invalid Host header" error to arise. Nothing seemed to help until I added the devServer config option shown below.
module.exports = {
//...
devServer: {
proxy: [
{
context: ['http://wsl:3000'],
target: 'http://localhost:3000',
},
],
},
}
This fixed the "bug" without introducing any security risks.
Reference: webpack DevServer docs
Try This one
<TouchableOpacity onPress={() => this._onPressAppoimentButton()} style={styles.Btn}>
<Button title="Order Online" style={styles.Btn} > </Button>
</TouchableOpacity>
This exception message doesn't mean it requires a primary key to be defined in your database, it means it requires a primary key to be defined in your class.
Although you've attempted to do so:
private Guid _id; [Key] public Guid ID { get { return _id; } }
This has no effect, as Entity Framework ignores read-only properties. It has to: when it retrieves a Fruits
record from the database, it constructs a Fruit
object, and then calls the property setters for each mapped property. That's never going to work for read-only properties.
You need Entity Framework to be able to set the value of ID
. This means the property needs to have a setter.
You don't put a component in directives
You register it in @NgModule
declarations:
@NgModule({
imports: [ BrowserModule ],
declarations: [ App , MyChildComponent ],
bootstrap: [ App ]
})
and then You just put it in the Parent's Template HTML as : <my-child></my-child>
That's it.
<nav class="navbar navbar-toggleable-md navbar-light bg-danger">
So you have this code here, you must be knowing that bg-danger
gives some sort of color.
Now if you want to give some custom color to your page then simply change bg-danger
to bg-color
.
Then either create a separate css-file or you can workout with style
element in same tag
.
Just do this-
`<nav class="navbar navbar-toggleable-md navbar-light bg-color" style="background-color: cyan;">` .
That would do.

I was then able to log in and run what I needed.
Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.
Another sneaky issue related to this is naming your columns with -
instead of _
.
Something like this will trigger an error at the moment your tables are getting created.
@Column(name="verification-token")
When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser
as the request body constructed from the original data. So when you advance in the chain, the next handler can read the same body.
One option is to read the whole body using ioutil.ReadAll()
, which gives you the body as a byte slice.
You may use bytes.NewBuffer()
to obtain an io.Reader
from a byte slice.
The last missing piece is to make the io.Reader
an io.ReadCloser
, because bytes.Buffer
does not have a Close()
method. For this you may use ioutil.NopCloser()
which wraps an io.Reader
, and returns an io.ReadCloser
, whose added Close()
method will be a no-op (does nothing).
Note that you may even modify the contents of the byte slice you use to create the "new" body. You have full control over it.
Care must be taken though, as there might be other HTTP fields like content-length and checksums which may become invalid if you modify only the data. If subsequent handlers check those, you would also need to modify those too!
If you also want to read the response body, then you have to wrap the http.ResponseWriter
you get, and pass the wrapper on the chain. This wrapper may cache the data sent out, which you can inspect either after, on on-the-fly (as the subsequent handlers write to it).
Here's a simple ResponseWriter
wrapper, which just caches the data, so it'll be available after the subsequent handler returns:
type MyResponseWriter struct {
http.ResponseWriter
buf *bytes.Buffer
}
func (mrw *MyResponseWriter) Write(p []byte) (int, error) {
return mrw.buf.Write(p)
}
Note that MyResponseWriter.Write()
just writes the data to a buffer. You may also choose to inspect it on-the-fly (in the Write()
method) and write the data immediately to the wrapped / embedded ResponseWriter
. You may even modify the data. You have full control.
Care must be taken again though, as the subsequent handlers may also send HTTP response headers related to the response data –such as length or checksums– which may also become invalid if you alter the response data.
Putting the pieces together, here's a full working example:
func loginmw(handler http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
body, err := ioutil.ReadAll(r.Body)
if err != nil {
log.Printf("Error reading body: %v", err)
http.Error(w, "can't read body", http.StatusBadRequest)
return
}
// Work / inspect body. You may even modify it!
// And now set a new body, which will simulate the same data we read:
r.Body = ioutil.NopCloser(bytes.NewBuffer(body))
// Create a response wrapper:
mrw := &MyResponseWriter{
ResponseWriter: w,
buf: &bytes.Buffer{},
}
// Call next handler, passing the response wrapper:
handler.ServeHTTP(mrw, r)
// Now inspect response, and finally send it out:
// (You can also modify it before sending it out!)
if _, err := io.Copy(w, mrw.buf); err != nil {
log.Printf("Failed to send out response: %v", err)
}
})
}
The direct parent of your child is markerDiv, so you should call remove from markerDiv as so:
markerDiv.removeChild(myCoolDiv);
Alternatively, you may want to remove markerNode. Since that node was appended directly to videoContainer, it can be removed with:
document.getElementById("playerContainer").removeChild(markerDiv);
Now, the easiest general way to remove a node, if you are absolutely confident that you did insert it into the DOM, is this:
markerDiv.parentNode.removeChild(markerDiv);
This works for any node (just replace markerDiv with a different node), and finds the parent of the node directly in order to call remove from it. If you are unsure if you added it, double check if the parentNode is non-null before calling removeChild.
Numpy arrays do not have an append method. Use the Numpy append function instead:
import numpy as np
array_3 = np.append(array_1, array_2, axis=n)
# you can either specify an integer axis value n or remove the keyword argument completely
For example, if array_1 and array_2 have the following values:
array_1 = np.array([1, 2])
array_2 = np.array([3, 4])
If you call np.append without specifying an axis value, like so:
array_3 = np.append(array_1, array_2)
array_3 will have the following value:
array([1, 2, 3, 4])
Else, if you call np.append with an axis value of 0, like so:
array_3 = np.append(array_1, array_2, axis=0)
array_3 will have the following value:
array([[1, 2],
[3, 4]])
More information on the append function here: https://docs.scipy.org/doc/numpy/reference/generated/numpy.append.html
Please do the import like below:
import { Router } from '@angular/Router';
The mistake that was being done was -> import { Router } from '@angular/router';
If you are using CORS middleware and you want to send withCredentials
boolean true, you can configure CORS like this:
var cors = require('cors'); _x000D_
app.use(cors({credentials: true, origin: 'http://localhost:5000'}));
_x000D_
`
As alternative you always can try a simpler workaround, using another icon, for example:
<button type="button" style="background:none;border:none">
<span class="fa fa-reorder"></span>
</button>
ref: https://www.w3schools.com/icons/fontawesome_icons_webapp.asp
<button type="button" style="background:none;border:none">
<span class="glyphicon glyphicon-align-justify"></span>
</button>
ref: https://www.w3schools.com/icons/bootstrap_icons_glyphicons.asp
So you gain total control over their color and size:
button span {
/*overwriting*/
color: white;
font-size: 25px;
}
(the button's style applied is just for a quick test):
Unity 5.6.1 / 2017.1 fixes the Android SDK Tools 25.3.1+ compatibility issue. This is noted in Unity bug tracker under issue 888859 and their 5.6.1 release notes.
if you have no systemctl and started the docker daemon by:
sudo service docker start
you can stop it by:
sudo service docker stop
That's what i am currrently working, what a coincidence.
You also need to add the following lines into your LoginController
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
class LoginController extends Controller
{
/*
|--------------------------------------------------------------------------
| Login Controller
|--------------------------------------------------------------------------
|
| This controller handles authenticating users for the application and
| redirecting them to your home screen. The controller uses a trait
| to conveniently provide its functionality to your applications.
|
*/
use AuthenticatesUsers;
protected function authenticated(Request $request, $user)
{
if ( $user->isAdmin() ) {// do your magic here
return redirect()->route('dashboard');
}
return redirect('/home');
}
/**
* Where to redirect users after login.
*
* @var string
*/
//protected $redirectTo = '/admin';
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('guest', ['except' => 'logout']);
}
}
First off, you shouldn't add $
when you're outside of strings ($class
in your first function being an exception), so it should be:
def doCopyMibArtefactsHere(projectName) {
step ([
$class: 'CopyArtifact',
projectName: projectName,
filter: '**/**.mib',
fingerprintArtifacts: true,
flatten: true
]);
}
def BuildAndCopyMibsHere(projectName, params) {
build job: project, parameters: params
doCopyMibArtefactsHere(projectName)
}
...
Now, as for your problem; the second function takes two arguments while you're only supplying one argument at the call. Either you have to supply two arguments at the call:
...
node {
stage('Prepare Mib'){
BuildAndCopyMibsHere('project1', null)
}
}
... or you need to add a default value to the functions' second argument:
def BuildAndCopyMibsHere(projectName, params = null) {
build job: project, parameters: params
doCopyMibArtefactsHere($projectName)
}
Best way is to use templating => add id to your input and then use it value
<input type="text" #notaryLockup (keyup) = "searchNotary(notaryLockup.value)"placeholder="Entrez des information" >
searchNotary(value: string) {
// your logic
}
this way you will never have Typescript error when strict verification is activated => See angular Docs
I'll add another case where I was getting the same error but just being a dummy. I had added [routerLinkActiveOptions]="{exact: true}"
without yet adding routerLinkActive="active"
.
My incorrect code was
<a class="nav-link active" routerLink="/dashboard" [routerLinkActiveOptions]="{exact: true}">
Home
</a>
when it should have been
<a class="nav-link active" routerLink="/dashboard" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">
Home
</a>
Without having routerLinkActive
, you can't have routerLinkActiveOptions
.
He's right. If you want to stay with jQuery you could do this
var ctx = $('#myChart')[0];
ctx.height = 500;
or
var ctx = $('#myChart');
ctx.attr('height',500);
Maybe you can use float:right;:
.one {_x000D_
padding-left: 1em;_x000D_
text-color: white;_x000D_
display:inline; _x000D_
}_x000D_
.two {_x000D_
background-color: #00ffff;_x000D_
}_x000D_
.pull-right{_x000D_
float:right;_x000D_
}

They dropped XS because Bootstrap is considered a mobile-first development tool. It's default is considered xs and so doesn't need to be defined.
What about this.

_x000D_
<p id ="p">This is some text</p>

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.
Discord supports Markdown and uses highlight.js to highlight code-blocks.
Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.
To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).
```language
message
```
Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).
Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.
No shadow and no rounded borders in the bar
You are using an image so the easiest solution is row your boat with the flow,
You cannot give heights manually,yes you can but make sure it gets enough space to show your full image view there
android:layout_height="wrap_content"
for SeekBar
I am no good with Photoshop but I managed to edit a background one for a test
seekbar_brown_to_show_progress.png
<SeekBar
android:splitTrack="false" // for unwanted white space in thumb
android:id="@+id/seekBar_luminosite"
android:layout_width="250dp" // use your own size
android:layout_height="wrap_content"
android:minHeight="10dp"
android:minWidth="15dp"
android:maxHeight="15dp"
android:maxWidth="15dp"
android:progress="50"
android:progressDrawable="@drawable/custom_seekbar_progress"
android:thumb="@drawable/custom_thumb" />
custom_seekbar_progress.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@android:id/background"
android:drawable="@drawable/seekbar" />
<item android:id="@android:id/progress">
<clip android:drawable="@drawable/seekbar_brown_to_show_progress" />
</item>
</layer-list>
custom_thumb.xml is same as yours
Finally android:splitTrack="false"
will remove the unwanted white space in your thumb
Let's have a look at the output :
Here are some ways of doing this:
For example, for using Roboto, install the package using
yarn add typeface-roboto
or
npm install typeface-roboto --save
In index.js:
import "typeface-roboto";
There are npm packages for a lot of open source fonts and most of Google fonts. You can see all fonts here. All the packages are from that project.
For example Google fonts, you can go to fonts.google.com where you can find links that you can put in your public/index.html
It'll be like
<link href="https://fonts.googleapis.com/css?family=Montserrat" rel="stylesheet">
or
<style>
@import url('https://fonts.googleapis.com/css?family=Montserrat');
</style>
Download the font. For example, for google fonts, you can go to fonts.google.com. Click on the download button to download the font.
Move the font to fonts
directory in your src
directory
src
|
`----fonts
| |
| `-Lato/Lato-Black.ttf
| -Lato/Lato-BlackItalic.ttf
| -Lato/Lato-Bold.ttf
| -Lato/Lato-BoldItalic.ttf
| -Lato/Lato-Italic.ttf
| -Lato/Lato-Light.ttf
| -Lato/Lato-LightItalic.ttf
| -Lato/Lato-Regular.ttf
| -Lato/Lato-Thin.ttf
| -Lato/Lato-ThinItalic.ttf
|
`----App.css
Now, in App.css
, add this
@font-face {
font-family: 'Lato';
src: local('Lato'), url(./fonts/Lato-Regular.otf) format('opentype');
}
@font-face {
font-family: 'Lato';
font-weight: 900;
src: local('Lato'), url(./fonts/Lato-Bold.otf) format('opentype');
}
@font-face {
font-family: 'Lato';
font-weight: 900;
src: local('Lato'), url(./fonts/Lato-Black.otf) format('opentype');
}
For ttf
format, you have to mention format('truetype')
. For woff
, format('woff')
Now you can use the font in classes.
.modal-title {
font-family: Lato, Arial, serif;
font-weight: black;
}
Install package using
yarn add webfontloader
or
npm install webfontloader --save
In src/index.js
, you can import this and specify the fonts needed
import WebFont from 'webfontloader';
WebFont.load({
google: {
families: ['Titillium Web:300,400,700', 'sans-serif']
}
});
kubectl -n <namespace-name> describe pod <pod name>
kubectl -n <namespace-name> logs -p <pod name>
You need to use entryComponents
under @NgModule
.
This is for dynamically added components that are added using ViewContainerRef.createComponent()
. Adding them to entryComponents tells the offline template compiler to compile them and create factories for them.
The components registered in route configurations are added automatically to entryComponents
as well because router-outlet
also uses ViewContainerRef.createComponent()
to add routed components to the DOM.
So your code will be like
@NgModule({
declarations: [
AppComponent,
LoginComponent,
DashboardComponent,
HomeComponent,
DialogResultExampleDialog
],
entryComponents: [DialogResultExampleDialog]
The ClientRepository should be annotated with @Repository
tag.
With your current configuration Spring will not scan the class and have knowledge about it. At the moment of booting and wiring will not find the ClientRepository class.
EDIT
If adding the @Repository
tag doesn't help, then I think that the problem might be now with the ClientService
and ClientServiceImpl
.
Try to annotate the ClientService
(interface) with @Service
. As you should only have a single implementation for your service, you don't need to specify a name with the optional parameter @Service("clientService")
. Spring will autogenerate it based on the interface' name.
Also, as Bruno mentioned, the @Qualifier
is not needed in the ClientController
as you only have a single implementation for the service.
ClientService.java
@Service
public interface ClientService {
void addClient(Client client);
}
ClientServiceImpl.java (option 1)
@Service
public class ClientServiceImpl implements ClientService{
private ClientRepository clientRepository;
@Autowired
public void setClientRepository(ClientRepository clientRepository){
this.clientRepository=clientRepository;
}
@Transactional
public void addClient(Client client){
clientRepository.saveAndFlush(client);
}
}
ClientServiceImpl.java (option 2/preferred)
@Service
public class ClientServiceImpl implements ClientService{
@Autowired
private ClientRepository clientRepository;
@Transactional
public void addClient(Client client){
clientRepository.saveAndFlush(client);
}
}
ClientController.java
@Controller
public class ClientController {
private ClientService clientService;
@Autowired
//@Qualifier("clientService")
public void setClientService(ClientService clientService){
this.clientService=clientService;
}
@RequestMapping(value = "registration", method = RequestMethod.GET)
public String reg(Model model){
model.addAttribute("client", new Client());
return "registration";
}
@RequestMapping(value = "registration/add", method = RequestMethod.POST)
public String addUser(@ModelAttribute Client client){
this.clientService.addClient(client);
return "home";
}
}
Judging from the messages you send via Socket.IO socket.emit('greet', { hello: 'Hey, Mr.Client!' });
, it seems that you are using the hackathon-starter
boilerplate. If so, the issue might be that express-status-monitor
module is creating its own socket.io instance, as per: https://github.com/RafalWilinski/express-status-monitor#using-module-with-socketio-in-project
You can either:
Pass in your socket.io instance and port as websocket
when you create the expressStatusMonitor
instance like below:
const server = require('http').Server(app);
const io = require('socket.io')(server);
...
app.use(expressStatusMonitor({ websocket: io, port: app.get('port') }));
for an android screen you can use this property elevation
.
for example :
HeaderView:{
backgroundColor:'#F8F8F8',
justifyContent:'center',
alignItems:'center',
height:60,
paddingTop:15,
//Its for IOS
shadowColor: '#000',
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.2,
// its for android
elevation: 5,
position:'relative',
},
I tested 3 methods to do that...
Method1:
const FriendCard:any = require('./../pages/FriendCard')
Method2:
import * as FriendCard from './../pages/FriendCard';
Method3:
if you can find something like this in tsconfig.json:
{ "compilerOptions": { ..., "allowJs": true }
then you can write:
import FriendCard from './../pages/FriendCard';
If you want to get whole response in JSON format, try this:
I have tried a new way to get whole response from server in JSON format without creating any model class. I am not using any model class to get data from server because I don't know what response I will get or it may change according to requirements.
this is JSON response:
{"contacts": [
{
"id": "c200",
"name": "sunil",
"email": "[email protected]",
"address": "xx-xx-xxxx,x - street, x - country",
"gender" : "male",
"phone": {
"mobile": "+91 0000000000",
"home": "00 000000",
"office": "00 000000"
}
},
{
"id": "c201",
"name": "Johnny Depp",
"email": "[email protected]",
"address": "xx-xx-xxxx,x - street, x - country",
"gender" : "male",
"phone": {
"mobile": "+91 0000000000",
"home": "00 000000",
"office": "00 000000"
}
},
.
.
.
]}
In your API interface change the parameter
public interface ApiInterface {
@POST("/index.php/User/login")//your api link
@FormUrlEncoded
Call<Object> getmovies(@Field("user_email_address") String title,
@Field("user_password") String body);
}
in your main activity where you are calling this
ApiInterface apiService =
ApiClient.getClient().create(ApiInterface.class);
Call call = apiService.getmovies("[email protected]","123456");
call.enqueue(new Callback() {
@Override
public void onResponse(Call call, Response response) {
Log.e("TAG", "response 33: "+new Gson().toJson(response.body()) );
}
@Override
public void onFailure(Call call, Throwable t) {
Log.e("TAG", "onFailure: "+t.toString() );
// Log error here since request failed
}
});
after that you can normally get parameter using JSON object and JSON array
Add click listener for item view in .onBindViewHolder() of your RecyclerView's adapter. get currently selected position and change color by .setBackground() for previously selected and current item
According the CORS filter documentation:
"Spring MVC provides fine-grained support for CORS configuration through annotations on controllers. However when used with Spring Security it is advisable to rely on the built-in CorsFilter that must be ordered ahead of Spring Security’s chain of filters"
Something like this will allow GET
access to the /ajaxUri
:
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class AjaxCorsFilter extends CorsFilter {
public AjaxCorsFilter() {
super(configurationSource());
}
private static UrlBasedCorsConfigurationSource configurationSource() {
CorsConfiguration config = new CorsConfiguration();
// origins
config.addAllowedOrigin("*");
// when using ajax: withCredentials: true, we require exact origin match
config.setAllowCredentials(true);
// headers
config.addAllowedHeader("x-requested-with");
// methods
config.addAllowedMethod(HttpMethod.OPTIONS);
config.addAllowedMethod(HttpMethod.GET);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/startAsyncAuthorize", config);
source.registerCorsConfiguration("/ajaxUri", config);
return source;
}
}
Of course, your SpringSecurity configuration must allow access to the URI with the listed methods. See @Hendy Irawan answer.
Claiming that the C++ compiler can produce more optimal code than a competent assembly language programmer is a very bad mistake. And especially in this case. The human always can make the code better than the compiler can, and this particular situation is a good illustration of this claim.
The timing difference you're seeing is because the assembly code in the question is very far from optimal in the inner loops.
(The below code is 32-bit, but can be easily converted to 64-bit)
For example, the sequence function can be optimized to only 5 instructions:
.seq:
inc esi ; counter
lea edx, [3*eax+1] ; edx = 3*n+1
shr eax, 1 ; eax = n/2
cmovc eax, edx ; if CF eax = edx
jnz .seq ; jmp if n<>1
The whole code looks like:
include "%lib%/freshlib.inc"
@BinaryType console, compact
options.DebugMode = 1
include "%lib%/freshlib.asm"
start:
InitializeAll
mov ecx, 999999
xor edi, edi ; max
xor ebx, ebx ; max i
.main_loop:
xor esi, esi
mov eax, ecx
.seq:
inc esi ; counter
lea edx, [3*eax+1] ; edx = 3*n+1
shr eax, 1 ; eax = n/2
cmovc eax, edx ; if CF eax = edx
jnz .seq ; jmp if n<>1
cmp edi, esi
cmovb edi, esi
cmovb ebx, ecx
dec ecx
jnz .main_loop
OutputValue "Max sequence: ", edi, 10, -1
OutputValue "Max index: ", ebx, 10, -1
FinalizeAll
stdcall TerminateAll, 0
In order to compile this code, FreshLib is needed.
In my tests, (1 GHz AMD A4-1200 processor), the above code is approximately four times faster than the C++ code from the question (when compiled with -O0
: 430 ms vs. 1900 ms), and more than two times faster (430 ms vs. 830 ms) when the C++ code is compiled with -O3
.
The output of both programs is the same: max sequence = 525 on i = 837799.
In case, when we have no control over child component, like a 3rd party library component.
We can use *ngIf
and setTimeout
to reset the child component from parent without making any change in child component.
.template:
.ts:
show:boolean = true
resetChildForm(){
this.show = false;
setTimeout(() => {
this.show = true
}, 100);
}

In my case ; what solved my issue was.....
You may had json like this, the keys without " double quotations....
{ name: "test", phone: "2324234" }
So try any online Json Validator to make sure you have right syntax...
Download the developer edition. There you can choose Express as license when installing.
It appears that the functionality previously present in the react-cookie
npm package has been moved to universal-cookie
. The relevant example from the universal-cookie repository now is:
import Cookies from 'universal-cookie';
const cookies = new Cookies();
cookies.set('myCat', 'Pacman', { path: '/' });
console.log(cookies.get('myCat')); // Pacman

I think the reason of this problem is when instant run is enabled, Android Studio don't put libraries such as firebase
into generated apk to decreasing project build time because firebase
library and other libraries such as maps
and others is exist in play services and play services is installed on android device so if instant run enabled don't need to put them in generated apk to make build time faster.
So when you extract apk and install it on another device you will see this exception
Add commons-collections4-x.x.jar file in your build path and try it again. It will work.
You can download it from https://mvnrepository.com/artifact/org.apache.commons/commons-collections4/4.0
Try this
button.addTarget(self, action:#selector(handleRegister()), for: .touchUpInside).
Just add parenthesis with name of method.
Also you can refer link : Value of type 'CustomButton' has no member 'touchDown'
(Angular 2 - Angular 7)
Component can be declared in a single module only. In order to use a component from another module, you need to do two simple tasks:
1st Module:
Have a component (lets call it: "ImportantCopmonent"), we want to re-use in the 2nd Module's page.
@NgModule({
declarations: [
FirstPage,
ImportantCopmonent // <-- Enable using the component html tag in current module
],
imports: [
IonicPageModule.forChild(NotImportantPage),
TranslateModule.forChild(),
],
exports: [
FirstPage,
ImportantCopmonent // <--- Enable using the component in other modules
]
})
export class FirstPageModule { }
2nd Module:
Reuses the "ImportantCopmonent", by importing the FirstPageModule
@NgModule({
declarations: [
SecondPage,
Example2ndComponent,
Example3rdComponent
],
imports: [
IonicPageModule.forChild(SecondPage),
TranslateModule.forChild(),
FirstPageModule // <--- this Imports the source module, with its exports
],
exports: [
SecondPage,
]
})
export class SecondPageModule { }
The simplest way will be use the react-copy-to-clipboard
npm package.
You can install it with the following command
npm install --save react react-copy-to-clipboard
Use it in the following manner.
const App = React.createClass({
getInitialState() {
return {value: '', copied: false};
},
onChange({target: {value}}) {
this.setState({value, copied: false});
},
onCopy() {
this.setState({copied: true});
},
render() {
return (
<div>
<input value={this.state.value} size={10} onChange={this.onChange} />
<CopyToClipboard text={this.state.value} onCopy={this.onCopy}>
<button>Copy</button>
</CopyToClipboard>
<div>
{this.state.copied ? <span >Copied.</span> : null}
</div>
<br />
<input type="text" />
</div>
);
}
});
ReactDOM.render(<App />, document.getElementById('container'));
A detailed explanation is provided at the following link
https://www.npmjs.com/package/react-copy-to-clipboard
Here is a running fiddle.
As the other answers explain well the error occurs because of invalid quote characters passed to the json module.
In my case I continued to get the ValueError even after replacing '
with "
in my string. What I finally realized was that some quote-like unicode symbols had found their way into my string:
“ ” ' ’ ‘ ` ´ " '
To clean all of these you can just pass your string through a regular expression:
import re
raw_string = '{“key”:“value”}'
parsed_string = re.sub(r"[“|”|'|’|‘|`|´|"|'|']", '"', my_string)
json_object = json.loads(parsed_string)
I built quicktype exactly for this purpose. Just paste your sample JSON and quicktype generates this type hierarchy for your API data:
struct Forecast {
let hourly: Hourly
let daily: Daily
let currently: Currently
let flags: Flags
let longitude: Double
let latitude: Double
let offset: Int
let timezone: String
}
struct Hourly {
let icon: String
let data: [Currently]
let summary: String
}
struct Daily {
let icon: String
let data: [Datum]
let summary: String
}
struct Datum {
let precipIntensityMax: Double
let apparentTemperatureMinTime: Int
let apparentTemperatureLowTime: Int
let apparentTemperatureHighTime: Int
let apparentTemperatureHigh: Double
let apparentTemperatureLow: Double
let apparentTemperatureMaxTime: Int
let apparentTemperatureMax: Double
let apparentTemperatureMin: Double
let icon: String
let dewPoint: Double
let cloudCover: Double
let humidity: Double
let ozone: Double
let moonPhase: Double
let precipIntensity: Double
let temperatureHigh: Double
let pressure: Double
let precipProbability: Double
let precipIntensityMaxTime: Int
let precipType: String?
let sunriseTime: Int
let summary: String
let sunsetTime: Int
let temperatureMax: Double
let time: Int
let temperatureLow: Double
let temperatureHighTime: Int
let temperatureLowTime: Int
let temperatureMin: Double
let temperatureMaxTime: Int
let temperatureMinTime: Int
let uvIndexTime: Int
let windGust: Double
let uvIndex: Int
let windBearing: Int
let windGustTime: Int
let windSpeed: Double
}
struct Currently {
let precipProbability: Double
let humidity: Double
let cloudCover: Double
let apparentTemperature: Double
let dewPoint: Double
let ozone: Double
let icon: String
let precipIntensity: Double
let temperature: Double
let pressure: Double
let precipType: String?
let summary: String
let uvIndex: Int
let windGust: Double
let time: Int
let windBearing: Int
let windSpeed: Double
}
struct Flags {
let sources: [String]
let isdStations: [String]
let units: String
}
It also generates dependency-free marshaling code to coax the return value of JSONSerialization.jsonObject
into a Forecast
, including a convenience constructor that takes a JSON string so you can quickly parse a strongly typed Forecast
value and access its fields:
let forecast = Forecast.from(json: jsonString)!
print(forecast.daily.data[0].windGustTime)
You can install quicktype from npm with npm i -g quicktype
or use the web UI to get the complete generated code to paste into your playground.
Ok. I found problem.
It was not on the Angular side. To be honest, there were no problem at all.
Reason why I was unable to perform my request succesfuly was that my server app was not properly handling OPTIONS request.
Why OPTIONS, not POST? My server app is on different host, then frontend. Because of CORS my browser was converting POST to OPTION: http://restlet.com/blog/2015/12/15/understanding-and-using-cors/
With help of this answer: Standalone Spring OAuth2 JWT Authorization Server + CORS
I implemented proper filter on my server-side app.
Thanks to @Supamiu - the person which fingered me that I am not sending POST at all.
You have to check the specific error within the javascript console (e.g. Ctrl + Shift + K in Firefox for Windows).
According to Steven Gliebe (2016), there are four common cases for this problem. If I may summarize it, as this:
After doing some code modification, please clear your browser cache as necessary.
In case there are other errors, you can check Google Maps API Error Codes Documentation page.
Some systems like Ubuntu, mysql is using by default the UNIX auth_socket plugin.
Basically means that: db_users using it, will be "auth" by the system user credentias. You can see if your root
user is set up like this by doing the following:
$ sudo mysql -u root # I had to use "sudo" since is new installation
mysql> USE mysql;
mysql> SELECT User, Host, plugin FROM mysql.user;
+------------------+-----------------------+
| User | plugin |
+------------------+-----------------------+
| root | auth_socket |
| mysql.sys | mysql_native_password |
| debian-sys-maint | mysql_native_password |
+------------------+-----------------------+
As you can see in the query, the root
user is using the auth_socket
plugin
There are 2 ways to solve this:
mysql_native_password
plugindb_user
with you system_user
(recommended)Option 1:
$ sudo mysql -u root # I had to use "sudo" since is new installation
mysql> USE mysql;
mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> exit;
$ sudo service mysql restart
Option 2: (replace YOUR_SYSTEM_USER with the username you have)
$ sudo mysql -u root # I had to use "sudo" since is new installation
mysql> USE mysql;
mysql> CREATE USER 'YOUR_SYSTEM_USER'@'localhost' IDENTIFIED BY 'YOUR_PASSWD';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'YOUR_SYSTEM_USER'@'localhost';
mysql> UPDATE user SET plugin='auth_socket' WHERE User='YOUR_SYSTEM_USER';
mysql> FLUSH PRIVILEGES;
mysql> exit;
$ sudo service mysql restart
Remember that if you use option #2 you'll have to connect to mysql as your system username (mysql -u YOUR_SYSTEM_USER
)
Note: On some systems (e.g., Debian stretch) 'auth_socket' plugin is called 'unix_socket', so the corresponding SQL command should be: UPDATE user SET plugin='unix_socket' WHERE User='YOUR_SYSTEM_USER';
Update:
from @andy's comment seems that mysql 8.x.x updated/replaced the auth_socket
for caching_sha2_password
I don't have a system setup with mysql 8.x.x to test this, however the steps above should help you to understand the issue. Here's the reply:
One change as of MySQL 8.0.4 is that the new default authentication plugin is 'caching_sha2_password'. The new 'YOUR_SYSTEM_USER' will have this auth plugin and you can login from the bash shell now with "mysql -u YOUR_SYSTEM_USER -p" and provide the password for this user on the prompt. No need for the "UPDATE user SET plugin" step. For the 8.0.4 default auth plugin update see, https://mysqlserverteam.com/mysql-8-0-4-new-default-authentication-plugin-caching_sha2_password/
I had the same problem. In my case, the reason is an extra comma.
I know this is old but given the IOptions patterns is relatively simple to implement:
Class with public get/set properties that match the settings in the configuration
public class ApplicationSettings
{
public string UrlBasePath { get; set; }
}
register your settings
public void ConfigureServices(IServiceCollection services)
{
...
services.Configure<ApplicationSettings>(Configuration.GetSection("ApplicationSettings"));
...
}
inject via IOptions
public class HomeController
{
public HomeController(IOptions<ApplicationSettings> appSettings)
{ ...
appSettings.Value.UrlBasePath
...
// or better practice create a readonly private reference
}
}
I'm not sure why you wouldn't just do this.
The accepted answer is correct in all means and I stumbled upon this thread after I couldn't get the Google Map render in one of my app components.
Now, if you are on a recent angular version i.e. 7+ of angular then you will have to deal with the following ViewChild declaration i.e.
@ViewChild(selector: string | Function | Type<any>, opts: {
read?: any;
static: boolean;
})
Now, the interesting part is the static value, which by definition says
Now for rendering a map, I used the following ,
@ViewChild('map', { static: true }) mapElement: any;
map: google.maps.Map;
Firstly, it is not related to Angular versions>2. Just import following in your app.module.ts file will fix the problems.
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
Then add FormsModule and ReactiveFormsModule in to your imports array.
imports: [
FormsModule,
ReactiveFormsModule
],
Note : You can also import ReactiveFormsModule
to specific module instead to app.module.ts
Above answer is partially correct for me, but In my scenario, I want to set the value to a state, because I have used the value to show/toggle a modal. So I have used like below. Hope it will help someone.
class Child extends React.Component {
state = {
visible:false
};
handleCancel = (e) => {
e.preventDefault();
this.setState({ visible: false });
};
componentDidMount() {
this.props.onRef(this)
}
componentWillUnmount() {
this.props.onRef(undefined)
}
method() {
this.setState({ visible: true });
}
render() {
return (<Modal title="My title?" visible={this.state.visible} onCancel={this.handleCancel}>
{"Content"}
</Modal>)
}
}
class Parent extends React.Component {
onClick = () => {
this.child.method() // do stuff
}
render() {
return (
<div>
<Child onRef={ref => (this.child = ref)} />
<button onClick={this.onClick}>Child.method()</button>
</div>
);
}
}

I ran into the same error, when I just forgot to declare my custom component in my NgModule
- check there, if the others solutions won't work for you.
This is an old question asked two years prior to my answer, I am going to post what worked for me anyways.
In my working directory I have two files: Dockerfile & provision.sh
Dockerfile:
FROM centos:6.8
# put the script in the /root directory of the container
COPY provision.sh /root
# execute the script inside the container
RUN /root/provision.sh
EXPOSE 80
# Default command
CMD ["/bin/bash"]
provision.sh:
#!/usr/bin/env bash
yum upgrade
I was able to make the file in the docker container executable by setting the file outside the container as executable chmod 700 provision.sh
then running docker build .
.
catch function in your api should either return some data which could be handled by Api call in React class or throw new error which should be caught using a catch function in your React class code. Latter approach should be something like:
return fetch(url)
.then(function(response){
return response.json();
})
.then(function(json){
return {
city: json.name,
temperature: kelvinToF(json.main.temp),
description: _.capitalize(json.weather[0].description)
}
})
.catch(function(error) {
console.log('There has been a problem with your fetch operation: ' + error.message);
// ADD THIS THROW error
throw error;
});
Then in your React Class:
Api(region.latitude, region.longitude)
.then((data) => {
console.log(data);
this.setState(data);
}).catch((error)=>{
console.log("Api call error");
alert(error.message);
});
If you want to due this in component.ts
HTML:
<button class="class1 class2" (click)="clicked($event)">Click me</button>
Component:
clicked(event) {
event.target.classList.add('class3'); // To ADD
event.target.classList.remove('class1'); // To Remove
event.target.classList.contains('class2'); // To check
event.target.classList.toggle('class4'); // To toggle
}

Use this <div [ngStyle]="{'background-image':'url('+imageUrl+')'}"></div>
this solved the problem for me.
Considering React Function Components and using Hooks are getting more popular these days , I will give a simple example of how to Passing data from child to parent component
in Parent Function Component we will have :
import React, { useState, useEffect } from "react";
then
const [childData, setChildData] = useState("");
and passing setChildData (which do a job similar to this.setState in Class Components) to Child
return( <ChildComponent passChildData={setChildData} /> )
in Child Component first we get the receiving props
function ChildComponent(props){ return (...) }
then you can pass data anyhow like using a handler function
const functionHandler = (data) => {
props.passChildData(data);
}
You need the secret string which was used to generate encrypt token. This code works for me:
protected string GetName(string token)
{
string secret = "this is a string used for encrypt and decrypt token";
var key = Encoding.ASCII.GetBytes(secret);
var handler = new JwtSecurityTokenHandler();
var validations = new TokenValidationParameters
{
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(key),
ValidateIssuer = false,
ValidateAudience = false
};
var claims = handler.ValidateToken(token, validations, out var tokenSecure);
return claims.Identity.Name;
}
Override constructor of DbContext Try this :-
public DataContext(DbContextOptions<DataContext> option):base(option) {}
wait.until(ExpectedConditions)
won't return null, it will either meet the condition or throw TimeoutException
.
You can check if the element is displayed and enabled
WebElement element = driver.findElement(By.xpath);
if (element.isDisplayed() && element.isEnabled()) {
element.click();
}
You have to disable the sandbox for Groovy in your job configuration.
Currently this is not possible for multibranch projects where the groovy script comes from the scm. For more information see https://issues.jenkins-ci.org/browse/JENKINS-28178
This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.
MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
headers);
JSONObject jsonObject = null;
try {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> responseEntity = restTemplate.exchange(
"https://url", HttpMethod.POST, entity,
String.class);
if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
try {
jsonObject = new JSONObject(responseEntity.getBody());
} catch (JSONException e) {
throw new RuntimeException("JSONException occurred");
}
}
} catch (final HttpClientErrorException httpClientErrorException) {
throw new ExternalCallBadRequestException();
} catch (HttpServerErrorException httpServerErrorException) {
throw new ExternalCallServerErrorException(httpServerErrorException);
} catch (Exception exception) {
throw new ExternalCallServerErrorException(exception);
}
ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.
Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.
I have had this issue also, and while -UseBasicParsing will work for some, if you actually need to interact with the dom it wont work. Try using a a group policy to stop the initial configuration window from ever appearing and powershell won't stop you anymore. See here https://wahlnetwork.com/2015/11/17/solving-the-first-launch-configuration-error-with-powershells-invoke-webrequest-cmdlet/
Took me just a few minutes once I found this page, once the GP is set, powershell will allow you through.
This is because the content of
<p myHighlight>Highlight me!</p>
has not been rendered when the constructor of the HighlightDirective is called so there is no content yet.
If you implement the AfterContentInit hook you will get the element and its content.
import { Directive, ElementRef, AfterContentInit } from '@angular/core';
@Directive({ selector: '[myHighlight]' })
export class HighlightDirective {
constructor(private el: ElementRef) {
//el.nativeElement.style.backgroundColor = 'yellow';
}
ngAfterContentInit(){
//you can get to the element content here
//this.el.nativeElement
}
}
Sometime in the future. Applicable to Windows 8.1 machine. Run the following commands
npm install -g @angular/cli
Log out or restart your machine.
This should add the required env path, rather than doing it manually.
<form (keydown)="someMethod($event)">
<input type="text">
</form>
someMethod(event:any){
if(event.keyCode == 13){
alert('Entered Click Event!');
}else{
}
}
I upgraded to Xcode 8, and iOS 10, but I had the problem.
I fixed it by going to project general tab, signing section.
Click "Enable signing....."
That is it.
It is important to remember that the driver(file) must have execution permission (linux chmod +x geckodriver).
To sum up:
Add system property:
System.setProperty("webdriver.gecko.driver", "FILE PATH");
Instantiate and use the class
WebDriver driver = new FirefoxDriver();
Do whatever you want
Close the driver
driver.close;
$emit
It dispatches an event name upwards through the scope hierarchy and notify to the registered $rootScope.Scope
listeners. The event life cycle starts at the scope on which $emit
was called. The event traverses upwards toward the root scope and calls all registered listeners along the way. The event will stop propagating if one of the listeners cancels it.
$broadcast
It dispatches an event name downwards to all child scopes (and their children) and notify to the registered $rootScope.Scope
listeners. The event life cycle starts at the scope on which $broadcast
was called. All listeners for the event on this scope get notified. Afterwards, the event traverses downwards toward the child scopes and calls all registered listeners along the way. The event cannot be canceled.
$on
It listen on events of a given type. It can catch the event dispatched by $broadcast
and $emit
.
Visual demo:

Running as admin didn't help me. (also got errors with syscall: rename)
Turns out this error can also occur if files are locked by Windows.
This can occur if :
Running as admin doesn't get around windows file locking.
I created a new project in VS2017 and then switched to VSCode to try to add more packages. After stopping the project from running and closing VS2017 it was able to complete without error
Disclaimer: I'm not exactly sure if this means running as admin isn't necessary, but try to avoid it if possible to avoid the possibility of some rogue package doing stuff it isn't meant to.

Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.
Hope this helps...
I just faced the same issue, I managed to make it work on my machine, however the change I did is not the same way it is mentioned in the documentation so it could be an issue of angular version routing module, mine is Angular 7
It only worked when I changed the lazy module main route entry path with same path as configured at the app-routes.ts
routes = [{path:'', redirectTo: '\home\default', pathMatch: 'full'},
{path: '',
children: [{
path:'home',
loadChildren :'lazy module path'
}]
}];
routes configured at HomeModule
const routes = [{path: 'home', redirectTo: 'default', pathMatch: 'full'},
{path: 'default', component: MyPageComponent},
]
instead of
const routes = [{path: '', redirectTo: 'default', pathMatch: 'full'},
{path: 'default', component: MyPageComponent},
]
Apply in ProGuard-rules

Already answered but I'd like to add a bit more on the topic and different ways to do it depending on your use case.
You can add adjustsFontSizeToFit={true}
(currently undocumented) to Text
Component to auto adjust the size inside a parent node.
<Text adjustsFontSizeToFit={true} numberOfLines={1}>Hiiiz</Text>
You can also add the following in your Text Component:
<Text style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>
Or you can add the following into the parent of the Text component:
<View style={{flex:1,justifyContent: "center",alignItems: "center"}}>
<Text>Hiiiz</Text>
</View>
or both
<View style={{flex:1,justifyContent: "center",alignItems: "center"}}>
<Text style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>
</View>
or all three
<View style={{flex:1,justifyContent: "center",alignItems: "center"}}>
<Text adjustsFontSizeToFit={true}
numberOfLines={1}
style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>
</View>
It all depends on what you're doing. You can also checkout my full blog post on the topic
Simply create a fallback to '' if the this.state.name is null.
<input name="name" type="text" value={this.state.name || ''} onChange={this.onFieldChange('name').bind(this)}/>
This also works with the useState variables.
I had a semicolon at the end, and gave me this error.
By default Kubernetes looks in the public Docker registry to find images. If your image doesn't exist there it won't be able to pull it.
You can run a local Kubernetes registry with the registry cluster addon.
Then tag your images with localhost:5000
:
docker tag aii localhost:5000/dev/aii
Push the image to the Kubernetes registry:
docker push localhost:5000/dev/aii
And change run-aii.yaml to use the localhost:5000/dev/aii
image instead of aii
. Now Kubernetes should be able to pull the image.
Alternatively, you can run a private Docker registry through one of the providers that offers this (AWS ECR, GCR, etc.), but if this is for local development it will be quicker and easier to get setup with a local Kubernetes Docker registry.
In python you can use json.Dump(str) before send result to html template. with this command string convert to correct json format and send to html template. After send this result to JSON.parse(result) , this is correct response and you can use this.

Spring Security can now leverage Spring MVC CORS support described in this blog post I wrote.
To make it work, you need to explicitly enable CORS support at Spring Security level as following, otherwise CORS enabled requests may be blocked by Spring Security before reaching Spring MVC.
If you are using controller level @CrossOrigin
annotations, you just have to enable Spring Security CORS support and it will leverage Spring MVC configuration:
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and()...
}
}
If you prefer using CORS global configuration, you can declare a CorsConfigurationSource
bean as following:
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and()...
}
@Bean
CorsConfigurationSource corsConfigurationSource() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
return source;
}
}
This approach supersedes the filter-based approach previously recommended.
You can find more details in the dedicated CORS section of Spring Security documentation.
Instead of dealing with zones and change detection — let AsyncPipe handle complexity. This will put observable subscription, unsubscription (to prevent memory leaks) and changes detection on Angular shoulders.
Change your class to make an observable, that will emit results of new requests:
export class RecentDetectionComponent implements OnInit {
recentDetections$: Observable<Array<RecentDetection>>;
constructor(private recentDetectionService: RecentDetectionService) {
}
ngOnInit() {
this.recentDetections$ = Observable.interval(5000)
.exhaustMap(() => this.recentDetectionService.getJsonFromApi())
.do(recent => console.log(recent[0].macAddress));
}
}
And update your view to use AsyncPipe:
<tr *ngFor="let detected of recentDetections$ | async">
...
</tr>
Want to add, that it's better to make a service with a method that will take interval
argument, and:
exhaustMap
like in code above);public static void DetachEntity<T>(this DbContext dbContext, T entity, string propertyName) where T: class, new()
{
try
{
var dbEntity = dbContext.Find<T>(entity.GetProperty(propertyName));
if (dbEntity != null)
dbContext.Entry(dbEntity).State = EntityState.Detached;
dbContext.Entry(entity).State = EntityState.Modified;
}
catch (Exception)
{
throw;
}
}
public static object GetProperty<T>(this T entity, string propertyName) where T : class, new()
{
try
{
Type type = entity.GetType();
PropertyInfo propertyInfo = type.GetProperty(propertyName);
object value = propertyInfo.GetValue(entity);
return value;
}
catch (Exception)
{
throw;
}
}
I made this 2 extension methods, this is working really well.
I looked at every solution (and tried a few) from this page but I was not convinced that we have to kind of implement a hack-ish way to achieve the data transfer between route.
Another problem with simple history.state
is that if you are passing an instance of a particular class in the state
object, it will not be the instance while receiving it. But it will be a plain simple JavaScript object.
So in my Angular v10 (Ionic v5) application, I did this-
this.router.navigateByUrl('/authenticate/username', {
state: {user: new User(), foo: 'bar'}
});
And in the navigating component ('/authenticate/username'
), in ngOnInit()
method, I printed the data with this.router.getCurrentNavigation().extras.state
-
ngOnInit() {
console.log('>>authenticate-username:41:',

And I got the desired data which was passed-
This is what worked for me:
This happens because there are too many unused methods. Most of these methods are coming from included libraries in your build.gradle
Use minify and shrink resources to fix this with gradle and clean up your code at the same time.
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

debug {

The options object can be added to the chart when the new Chart object is created.
var chart1 = new Chart(canvas, {
type: "pie",

tooltips: {
enabled: false
}
}
});
I got my solution
var claim = HttpContext.User.CurrentUserID();
public static class XYZ
{
public static int CurrentUserID(this ClaimsPrincipal claim)
{
var userID = claimsPrincipal.Claims.ToList().Find(r => r.Type ==
"UserID").Value;
return Convert.ToInt32(userID);
}
public static string CurrentUserRole(this ClaimsPrincipal claim)
{
var role = claimsPrincipal.Claims.ToList().Find(r => r.Type ==
"Role").Value;
return role;
}
}
There's now a simpler way with .NET Standard
or .NET Core
:
var client = new HttpClient();
var response = await client.PostAsync(uri, myRequestObject, new JsonMediaTypeFormatter());
NOTE: In order to use the JsonMediaTypeFormatter
class, you will need to install the Microsoft.AspNet.WebApi.Client
NuGet package, which can be installed directly, or via another such as Microsoft.AspNetCore.App
.
Using this signature of HttpClient.PostAsync
, you can pass in any object and the JsonMediaTypeFormatter
will automatically take care of serialization etc.
With the response, you can use HttpContent.ReadAsAsync<T>
to deserialize the response content to the type that you are expecting:
var responseObject = await response.Content.ReadAsAsync<MyResponseType>();
Your test requires a ServletContext: add @WebIntegrationTest
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT
...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html
UPDATE
In Spring Boot 1.4.x and above @WebIntegrationTest
is no longer preferred. @SpringBootTest
or @WebMvcTest
I was facing the same problem and how i resolved see below steps or Image:
I had this error with MySQL as my database and the only solution was reinstall all components of MySQL, because before I installed just the server.
So try to download other versions of PostgreSQL and get all the components
It works if you remove flexDirection: row
from descriptionContainerVer
and descriptionContainerVer2
respectively.
UPDATE (see comments)
I made a few changes to achieve what I think you're after. First of all I removed the descriptionContainerHor
component. Then I set the flexDirection
of the vertical views to row
and added alignItems: 'center'
and justifyContent: 'center'
. Since the vertical views are now in fact stacked along the horizontal axis I removed the Ver
part from the name.
So now you have a wrapper view that should vertically and horizontally align it's content and stack it along the x-axis. I then simply put two invisible View
components on the left and right side of the Text
component to do the padding.
Like this:
<View style={styles.descriptionContainer}>
<View style={styles.padding}/>
<Text style={styles.descriptionText} numberOfLines={5} >
Here is a really long text that you can do nothing about, its gonna be long wether you like it or not, so be prepared for it to go off screen. Right? Right..!
</Text>
<View style={styles.padding}/>
</View>
And this:
descriptionContainer:{
flex:0.5, //height (according to its parent),
flexDirection: 'row',
backgroundColor: 'blue',
alignItems: 'center',
justifyContent: 'center',
// alignSelf: 'center',
},
padding: {
flex: 0.1
},
descriptionText: {
backgroundColor: 'green',//Colors.transparentColor,
fontSize: 16,
flex: 0.8,
color: 'white',
textAlign: 'center',
flexWrap: 'wrap'
},
Then you get what I believe you were after.
FURTHER IMPROVEMENTS
Now if you would like to stack multiple text areas within the blue and orange views you can do something like this:
<View style={styles.descriptionContainer2}>
<View style={styles.padding}/>
<View style={styles.textWrap}>
<Text style={styles.descriptionText} numberOfLines={5} >
Some other long text which you can still do nothing about.. Off the screen we go then.
</Text>
<Text style={styles.descriptionText} numberOfLines={5} >
Another column of text.
</Text>
</View>
<View style={styles.padding}/>
</View>
Where textWrap
is styled like this:
textWrap: {
flexDirection: 'column',
flex: 0.8
},
Hope this helps!
Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?

You can use ConnectivityManager.
val cm = getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
val activeNetwork: NetworkInfo? = cm.activeNetworkInfo
val dialogBuilder = AlertDialog.Builder(this)
if (activeNetwork!=null) // Some network is available
{
if (activeNetwork.isConnected) { // Network is connected to internet
}else{ // Network is NOT connected to internet
}
Just create a button element with jQuery, and add the event handler when you create it :
var div = $('<div />', {'data-role' : 'fieldcontain'}),
btn = $('<input />', {
type : 'button',
value : 'Dynamic Button',
id : 'btn_a',
on : {
click: function() {
alert ( this.value );
}
}
});
div.append(btn).appendTo( $('#pg_menu_content').empty() );
An adaptation of unutbu's answer that I found useful in my own code:
example_dict.setdefaut('key1', {}).get('key2')
It generates a dictionary entry for key1 if it does not have that key already so that you avoid the KeyError. If you want to end up a nested dictionary that includes that key pairing anyway like I did, this seems like the easiest solution.
Working with just one class:
select {
width: 268px;
padding: 5px;
font-size: 16px;
line-height: 1;
border: 0;
border-radius: 5px;
height: 34px;
background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right #ddd;
-webkit-appearance: none;
background-position-x: 244px;
}
This works on Windows with Cygwin installed:
System.getenv("NUMBER_OF_PROCESSORS")
This approach resolved my issue to allow multiple domain
app.use(function(req, res, next) {
var allowedOrigins = ['http://127.0.0.1:8020', 'http://localhost:8020', 'http://127.0.0.1:9000', 'http://localhost:9000'];
var origin = req.headers.origin;
if(allowedOrigins.indexOf(origin) > -1){
res.setHeader('Access-Control-Allow-Origin', origin);
}
//res.header('Access-Control-Allow-Origin', 'http://127.0.0.1:8020');
res.header('Access-Control-Allow-Methods', 'GET, OPTIONS');
res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization');
res.header('Access-Control-Allow-Credentials', true);
return next();
});
Integer.toString
calls the static method in the class Integer
. It does not need an instance of Integer
.
If you call new Integer(i)
you create an instance of type Integer
, which is a full Java object encapsulating the value of your int. Then you call the toString
method on it to ask it to return a string representation of itself.
If all you want is to print an int
, you'd use the first one because it's lighter, faster and doesn't use extra memory (aside from the returned string).
If you want an object representing an integer value—to put it inside a collection for example—you'd use the second one, since it gives you a full-fledged object to do all sort of things that you cannot do with a bare int
.
One of the putty tools is pscp.exe; it will allow you to copy files from your remote host.
The only thing that worked for me:
g.drawOval((getWidth()-200)/2,(getHeight()-200)/2, 200, 200);
The thread's a little old. But from the title I thought it had promise for my needs. Unfortunately, my structure didn't lend itself easily to the nth-of-type solution. Here's a Thymeleaf solution.

Your column is nullable
int maxAge = context.Persons.Select(p => p.Age).Max() ?? 0;
Your column is non-nullable
int maxAge = context.Persons.Select(p => p.Age).Cast<int?>().Max() ?? 0;
In both cases, you can use the second code. If you use DefaultIfEmpty
, you will do a bigger query on your server. For people who are interested, here are the EF6 equivalent:
Query without DefaultIfEmpty
SELECT
[GroupBy1].[A1] AS [C1]
FROM ( SELECT
MAX([Extent1].[Age]) AS [A1]
FROM [dbo].[Persons] AS [Extent1]
) AS [GroupBy1]
Query with DefaultIfEmpty
SELECT
[GroupBy1].[A1] AS [C1]
FROM ( SELECT
MAX([Join1].[A1]) AS [A1]
FROM ( SELECT
CASE WHEN ([Project1].[C1] IS NULL) THEN 0 ELSE [Project1].[Age] END AS [A1]
FROM ( SELECT 1 AS X ) AS [SingleRowTable1]
LEFT OUTER JOIN (SELECT
[Extent1].[Age] AS [Age],
cast(1 as tinyint) AS [C1]
FROM [dbo].[Persons] AS [Extent1]) AS [Project1] ON 1 = 1
) AS [Join1]
) AS [GroupBy1]
You need to import moment() the function and Moment the class separately in TS.
I found a note in the typescript docs here.
/*~ Note that ES6 modules cannot directly export callable functions
*~ This file should be imported using the CommonJS-style:
*~ import x = require('someLibrary');
So the code to import moment js into typescript actually looks like this:
import { Moment } from 'moment'
....
let moment = require('moment');
...
interface SomeTime {
aMoment: Moment,
}
...
fn() {
...
someTime.aMoment = moment(...);
...
}
I had a similar problem. I created a new repository, NOT IN THE DIRECTORY THAT I WANTED TO MAKE A REPOSITORY. I then copied the files created to the directory I wanted to make a repository. Then open an existing repository using the directory I just copied the files to.
NOTE: I did use github desktop to make and open exiting repository.
I'll offer an oddball alternative. Sometimes it's easier to use different encoding, especially if you're dealing with a variety of systems that don't all handle the details of URL encoding the same way. This isn't the most mainstream approach but can come in handy in certain situations.
Rather than URL-encoding the data, you can base64-encode it. The benefit of this is the encoded data is very generic, consisting only of alpha characters and sometimes trailing =
's. Example:
JSON array-of-strings:
["option", "Fred's dog", "Bill & Trudy", "param=3"]
That data, URL-encoded as the data
param:
"data=%5B%27option%27%2C+%22Fred%27s+dog%22%2C+%27Bill+%26+Trudy%27%2C+%27param%3D3%27%5D"
Same, base64-encoded:
"data=WyJvcHRpb24iLCAiRnJlZCdzIGRvZyIsICJCaWxsICYgVHJ1ZHkiLCAicGFyYW09MyJd"
The base64 approach can be a bit shorter, but more importantly it's simpler. I often have problems moving URL-encoded data between cURL, web browsers and other clients, usually due to quotes, embedded %
signs and so on. Base64 is very neutral because it doesn't use special characters.
int a,b,c,d;
if(scanf("%d %d %d %d",&a,&b,&c,&d) == 4) {
//read the 4 integers
} else {
puts("Error. Please supply 4 integers");
}
You could create a patch from the commits that you want to copy and apply the patch to the destination branch.
I found this;
from here;
vba- Can a combobox present more then one column on it's textbox part?
and this may help;
I added a sort of demo here;
It will give you point of hook to put some code that you wish to be executed on web application deploy time
t(sapply(a, '[', 1:max(sapply(a, length))))
where 'a' is a list. Would work for unequal row size
I really don't know what was so hard about this question, but I managed to do it this way:
[myStringContainingInt intValue];
It should be noted that you can also do:
myStringContainingInt.intValue;
Yes, JSON.stringify
, can be found here, it's included in Firefox 3.5.4 and above.
A JSON stringifier goes in the opposite direction, converting JavaScript data structures into JSON text. JSON does not support cyclic data structures, so be careful to not give cyclical structures to the JSON stringifier. https://web.archive.org/web/20100611210643/http://www.json.org/js.html
var myJSONText = JSON.stringify(myObject, replacer);
You can get the actual height of called layout with this code:
public int getLayoutSize() {
// Get the layout id
final LinearLayout root = (LinearLayout) findViewById(R.id.mainroot);
final AtomicInteger layoutHeight = new AtomicInteger();
root.post(new Runnable() {
public void run() {
Rect rect = new Rect();
Window win = getWindow(); // Get the Window
win.getDecorView().getWindowVisibleDisplayFrame(rect);
// Get the height of Status Bar
int statusBarHeight = rect.top;
// Get the height occupied by the decoration contents
int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
// Calculate titleBarHeight by deducting statusBarHeight from contentViewTop
int titleBarHeight = contentViewTop - statusBarHeight;
Log.i("MY", "titleHeight = " + titleBarHeight + " statusHeight = " + statusBarHeight + " contentViewTop = " + contentViewTop);
// By now we got the height of titleBar & statusBar
// Now lets get the screen size
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenHeight = metrics.heightPixels;
int screenWidth = metrics.widthPixels;
Log.i("MY", "Actual Screen Height = " + screenHeight + " Width = " + screenWidth);
// Now calculate the height that our layout can be set
// If you know that your application doesn't have statusBar added, then don't add here also. Same applies to application bar also
layoutHeight.set(screenHeight - (titleBarHeight + statusBarHeight));
Log.i("MY", "Layout Height = " + layoutHeight);
// Lastly, set the height of the layout
FrameLayout.LayoutParams rootParams = (FrameLayout.LayoutParams)root.getLayoutParams();
rootParams.height = layoutHeight.get();
root.setLayoutParams(rootParams);
}
});
return layoutHeight.get();
}
So the way I would solve this problem is to make sure the two datetimes are in the right timezone.
I can see that you are using datetime.now()
which will return the systems current time, with no tzinfo set.
tzinfo is the information attached to a datetime to let it know what timezone it is in. If you are using naive datetime you need to be consistent through out your system. I would highly recommend only using datetime.utcnow()
seeing as somewhere your are creating datetime that have tzinfo associated with them, what you need to do is make sure those are localized (has tzinfo associated) to the correct timezone.
Take a look at Delorean, it makes dealing with this sort of thing much easier.

It depends what is a use of those tables, but you might consider putting trigger on original table on insert and update. When insert or update is done, update the second table based on only one item from the original table. It will be quicker.
I had this problem, but I didn't want to use annotation in my entities, so I solved by creating a constructor for my class, this constructor must not have a reference back to the entities who references this entity. Let's say this scenario.
public class A{
private int id;
private String code;
private String name;
private List<B> bs;
}
public class B{
private int id;
private String code;
private String name;
private A a;
}
If you try to send to the view the class B
or A
with @ResponseBody
it may cause an infinite loop. You can write a constructor in your class and create a query with your entityManager
like this.
"select new A(id, code, name) from A"
This is the class with the constructor.
public class A{
private int id;
private String code;
private String name;
private List<B> bs;
public A(){
}
public A(int id, String code, String name){
this.id = id;
this.code = code;
this.name = name;
}
}
However, there are some constrictions about this solution, as you can see, in the constructor I did not make a reference to List bs this is because Hibernate does not allow it, at least in version 3.6.10.Final, so when I need to show both entities in a view I do the following.
public A getAById(int id); //THE A id
public List<B> getBsByAId(int idA); //the A id.
The other problem with this solution, is that if you add or remove a property you must update your constructor and all your queries.
To check that the file you're trying to open actually exists, you can change directories in terminal using cd
. To change to ~/Desktop/sass/css
: cd ~/Desktop/sass/css
. To see what files are in the directory: ls
.
If you want information about either of those commands, use the man
page: man cd
or man ls
, for example.
Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.
On Mac OS X, you can also use open
to open a finder window: open .
will open the current directory in finder. (open ~/Desktop/sass/css
will open the ~/Desktop/sass/css
).
The "proper" LaTeX ways to do it is to use a package which allows you to specify the spacing you want. There are several such package, and these two pages link to lists of them...
Your problem is that you have key
and value
in quotes making them strings, i.e. you're setting aKey
to contain the string "key"
and not the value of the variable key
. Also, you're not clearing out the temp
list, so you're adding to it each time, instead of just having two items in it.
To fix your code, try something like:
for key, value in dict.iteritems():
temp = [key,value]
dictlist.append(temp)
You don't need to copy the loop variables key
and value
into another variable before using them so I dropped them out. Similarly, you don't need to use append to build up a list, you can just specify it between square brackets as shown above. And we could have done dictlist.append([key,value])
if we wanted to be as brief as possible.
Or just use dict.items()
as has been suggested.
This is what I use, regardless boundaries and matrix transformations:
function clearCanvas(canvas) {
const ctx = canvas.getContext('2d');
ctx.save();
ctx.globalCompositeOperation = 'copy';
ctx.strokeStyle = 'transparent';
ctx.beginPath();
ctx.lineTo(0, 0);
ctx.stroke();
ctx.restore();
}
Basically, it saves the current state of the context, and draws a transparent pixel with copy
as globalCompositeOperation
. Then, restores the previous context state.
If, for example, x = 5 and is stored as string, you can also just:
x = x + 0
and the new x would be stored as a numeric value.
They are both going to have the same effect.
However, as pointed out in the comments: $(window).scrollTop()
is supported by more web browsers than $('html').scrollTop()
.
Take a look at the System.Net.WebClient
class, it can be used to issue requests and handle their responses, as well as to download files:

http://msdn.microsoft.com/en-us/library/system.net.webclient(VS.90).aspx
File file = ...
byte[] data = ...
try{
FileOutputStream fos = FileOutputStream(file);
fos.write(data);
fos.flush();
fos.close();
}catch(Exception e){
}
but if the bytes array length is more than 1024 you should use loop to write the data.
final EditText edittext = (EditText) findViewById(R.id.edittext);
edittext.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// If the event is a key-down event on the "enter" button
if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
(keyCode == KeyEvent.KEYCODE_ENTER)) {
// Perform action on key press
Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
You don't have to define a separate variable in the widget scope, just do it inline:
TextField(
controller: TextEditingController()..text = 'Your initial value',
onChanged: (text) => {},
)
Just got a solution to get height and width of a custom view:
@Override
protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld){
super.onSizeChanged(xNew, yNew, xOld, yOld);
viewWidth = xNew;
viewHeight = yNew;
}
Its working in my case.
It depends..
SELECT x.col
FROM big_table x
WHERE x.key IN( SELECT key FROM really_big_table );
would not be relatively slow the isn't much to limit size of what the query check to see if they key is in. EXISTS would be preferable in this case.
But, depending on the DBMS's optimizer, this could be no different.
As an example of when EXISTS is better
SELECT x.col
FROM big_table x
WHERE EXISTS( SELECT key FROM really_big_table WHERE key = x.key);
AND id = very_limiting_criteria
The div
elements are block elements, so by default they take upp the full available width.
One way is to turn them into inline elements:
.label, .text { display: inline; }
This will have the same effect as using span
elements instead of div
elements.
Another way is to float the elements:
.label, .text { float: left; }
This will change how the width of the elements is decided, so that thwy will only be as wide as their content. It will also make the elements float beside each other, similar to how images flow beside each other.
You can also consider changing the elements. The div
element is intended for document divisions, I usually use a label
and a span
element for a construct like this:
<label>My Label:</label>
<span>My text</span>
If you're interested in generalizing to different architectures, you could also run the command above and substitute uname -m
in with backticks like so:
wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-`uname -m`.sh
Choose either:
a) Create not null with some valid default value
b) Create null, fill it, alter to not null

Add the NUnit test adapter NuGet package to your test projects
Or install the Test Adapter Visual Studio extension. There is one for

Math.Round(a, 2); //returns 1.99
decimal b = 1.995555M;

You might also want to look at bankers rounding / round-to-even with the following overload:
Math.Round(a, 2, MidpointRounding.ToEven);

MongoDB can be confusing regarding the dbPath
folder.
When you run mongod
without dbpath
then the default path is /data/db
However when you start it as a service, e.g. systemctl start mongod
then it reads on configuration file, typially /etc/mongod.cfg
and in this config file the defaults are
Platform | Package Manager | Default storage.dbPath |
---|---|---|
RHEL / CentOS and Amazon | yum | /var/lib/mongo |
SUSE | zypper | /var/lib/mongo |
Ubuntu and Debian | apt | /var/lib/mongodb |
macOS | brew | /usr/local/var/mongodb |
So, by accident your MongoDB tries to access different data folders depending on how you start the service.
All you need to do now is a simple git checkout
Just make sure to enable it via this global config: git config --global submodule.recurse true
There are a couple generic types in .Net (v2 and later) that make passing functions around as delegates very easy.
For functions with return types, there is Func<> and for functions without return types there is Action<>.
Both Func and Action can be declared to take from 0 to 4 parameters. For example, Func < double, int > takes one double as a parameter and returns an int. Action < double, double, double > takes three doubles as parameters and returns nothing (void).
So you can declare your Diff function to take a Func:
public double Diff(double x, Func<double, double> f) {
double h = 0.0000001;
return (f(x + h) - f(x)) / h;
}
And then you call it as so, simply giving it the name of the function that fits the signature of your Func or Action:
double result = Diff(myValue, Function);
You can even write the function in-line with lambda syntax:
double result = Diff(myValue, d => Math.Sqrt(d * 3.14));
I am posting an answer to provide an updated solution and explanation as to why this problem can occur. Say you are getting this data from a database or Excel workbook. If you have special characters like La Cañada Flintridge city
, well unless you are exporting the data using UTF-8
encoding, you're going to introduce errors. La Cañada Flintridge city
will become La Ca\xf1ada Flintridge city
. If you are using pandas.read_csv
without any adjustments to the default parameters, you'll hit the following error
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 5: invalid continuation byte
Fortunately, there are a few solutions.
Option 1, fix the exporting. Be sure to use UTF-8
encoding.
Option 2, if fixing the exporting problem is not available to you, and you need to use pandas.read_csv
, be sure to include the following paramters, engine='python'
. By default, pandas uses engine='C'
which is great for reading large clean files, but will crash if anything unexpected comes up. In my experience, setting encoding='utf-8'
has never fixed this UnicodeDecodeError
. Also, you do not need to use errors_bad_lines
, however, that is still an option if you REALLY need it.
pd.read_csv(<your file>, engine='python')
Option 3: solution is my preferred solution personally. Read the file using vanilla Python.
import pandas as pd
data = []
with open(<your file>, "rb") as myfile:
# read the header seperately
# decode it as 'utf-8', remove any special characters, and split it on the comma (or deliminator)
header = myfile.readline().decode('utf-8').replace('\r\n', '').split(',')

Hope this helps people encountering this issue for the first time.
Direct use of .reduce
can be hard to read, so I'd recommend creating a function that generates the reducer for you:
function mapfilter(mapper) {
return (acc, val) => {
const mapped = mapper(val);
if (mapped !== false)
acc.push(mapped);
return acc;
};
}
Use it like so:
const words = "Map and filter an array #javascript #arrays";
const tags = words.split(' ')
.reduce(mapfilter(word => word.startsWith('#') && word.slice(1)), []);
console.log(tags); // ['javascript', 'arrays'];
Can be used as a one-liner too:
function repeat(arr, len) {
while (arr.length < len) arr = arr.concat(arr.slice(0, len-arr.length));
return arr;
}
This is because the path of image is wrong or the name of image you write is incorrect .
how to check? first try to print the image using print(img) if it prints 'None' that means you have given wrong image path correct that path and try again.
You can try use this function to find any object in nested nested array of arrays of kings.
Example
function findTByKeyValue (element, target){
var found = true;
for(var key in target) {
if (!element.hasOwnProperty(key) || element[key] !== target[key]) {
found = false;
break;
}
}
if(found) {
return element;
}
if(typeof(element) !== "object") {
return false;
}
for(var index in element) {
var result = findTByKeyValue(element[index],target);
if(result) {
return result;
}
}
};
findTByKeyValue(problems,{"name":"somethingElse","strength":"500 mg"}) =====> result equal to object associatedDrug#2
Ok, solved my problem, if anyone is passing by here is the answer:
Just had to add left: 0,
and top: 0,
to the styles, and yes, I'm tired.
position: 'absolute',
left: 0,
top: 0,
Relative to what, your application ? If so then you can simply get the applications current Path with :
System.Environment.CurrentDirectory
And append it to the connection string
glob2rx()
converts a pattern including a wildcard into the equivalent regular expression. You then need to pass this regular expression onto one of R's pattern matching tools.
If you want to match "blue*"
where *
has the usual wildcard, not regular expression, meaning we use glob2rx()
to convert the wildcard pattern into a useful regular expression:
> glob2rx("blue*")
[1] "^blue"
The returned object is a regular expression.
Given your data:
x <- c('red','blue1','blue2', 'red2')
we can pattern match using grep()
or similar tools:
> grx <- glob2rx("blue*")
> grep(grx, x)
[1] 2 3
> grep(grx, x, value = TRUE)
[1] "blue1" "blue2"
> grepl(grx, x)
[1] FALSE TRUE TRUE FALSE
As for the selecting rows problem you posted
> a <- data.frame(x = c('red','blue1','blue2', 'red2'))
> with(a, a[grepl(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
> with(a, a[grep(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
or via subset()
:
> with(a, subset(a, subset = grepl(grx, x)))
x
2 blue1
3 blue2
Hope that explains what grob2rx()
does and how to use it?
JQuery and PHP
In PHP file "contenido.php":
<?php
$mURL = $_GET['url'];
echo file_get_contents($mURL);
?>
In html:
<script type="text/javascript" src="js/jquery/jquery.min.js"></script>
<script type="text/javascript">
function getContent(pUrl, pDivDestino){
var mDivDestino = $('#'+pDivDestino);
$.ajax({
type : 'GET',
url : 'contenido.php',
dataType : 'html',
data: {
url : pUrl
},
success : function(data){
mDivDestino.html(data);
}
});
}
</script>
<a href="#" onclick="javascript:getContent('http://www.google.com/', 'contenido')">Get Google</a>
<div id="contenido"></div>
You can use strtotime
:
$date = strtotime('2010-01-01 -1 year');
The strtotime
function returns a unix timestamp, to get a formatted string you can use date
:
echo date('Y-m-d', $date); // echoes '2009-01-01'
Set the horizontalPolicy & VerticalPolicy for the controls/widgets to "Preferred".
http://www.markrafferty.com/wp-content/w3tc/min/7415c412.e68ae1.css
Line 11:
.postItem img {
height: auto;
width: 450px;
}
You can either edit your CSS, or you can listen to Mageek and use INLINE STYLING to override the CSS styling that's happening:
<img src="theSource" style="width:30px;" />
Avoid setting both width and height, as the image itself might not be scaled proportionally. But you can set the dimensions to whatever you want, as per Mageek's example.
% ps -o args -C nginx
COMMAND
build/sbin/nginx -c ../test.conf
If nginx was run without the -c
option, then you can use the -V
option to find out the configure arguments that were set to non-standard values. Among them the most interesting for you are:
--prefix=PATH set installation prefix
--sbin-path=PATH set nginx binary pathname
--conf-path=PATH set nginx.conf pathname
If you are using this for Angular, then export a function via a named export. Such as:
function someFunc(){}
export { someFunc as someFuncName }
otherwise, Angular will complain that object is not a function.
Your problem may be that you are dealing with DATETIME data, not just dates. If a row has a mydate that is '2008-11-25 09:30 AM', then your WHERE mydate<='2008-11-25'; is not going to return that row. '2008-11-25' has an implied time of 00:00 (midnight), so even though the date part is the same, they are not equal, and mydate is larger.
If you use < '2008-11-26' instead of <= '2008-11-25', that would work. The Datediff method works because it compares just the date portion, and ignores the times.
CSS can be applied and you will have to set transform-origin
correctly to get the applied transformation in the way you want
See the fiddle:
http://jsfiddle.net/OMS_/gkrsz/
Main code:
/* assuming that the image's height is 70px */
img.rotated {
transform: rotate(90deg);
-webkit-transform: rotate(90deg);
-moz-transform: rotate(90deg);
-ms-transform: rotate(90deg);
transform-origin: 35px 35px;
-webkit-transform-origin: 35px 35px;
-moz-transform-origin: 35px 35px;
-ms-transform-origin: 35px 35px;
}
jQuery and JS:
$(img)
.css('transform-origin-x', imgWidth / 2)
.css('transform-origin-y', imgHeight / 2);
// By calculating the height and width of the image in the load function
// $(img).css('transform-origin', (imgWidth / 2) + ' ' + (imgHeight / 2) );
Logic:
Divide the image's height by 2. The transform-x
and transform-y
values should be this value
Link:
transform-origin at CSS | MDN
Well... I've found some issues in every proposed solution here.
Here is my solution that include jQuery
.fn
instance function and expression
. I've created more variables inside my function than I could, but for complex logical problem I like to divide it into smaller, clearly named pieces.
I'm using getBoundingClientRect
method that returns element position relatively to the viewport so I don't need to care about scroll position
Useage:
$(".some-element").filter(":onscreen").doSomething();
$(".some-element").filter(":entireonscreen").doSomething();
$(".some-element").isOnScreen(); // true / false
$(".some-element").isOnScreen(true); // true / false (partially on screen)
$(".some-element").is(":onscreen"); // true / false (partially on screen)
$(".some-element").is(":entireonscreen"); // true / false
Source:
$.fn.isOnScreen = function(partial){
//let's be sure we're checking only one element (in case function is called on set)
var t = $(this).first();
//we're using getBoundingClientRect to get position of element relative to viewport
//so we dont need to care about scroll position
var box = t[0].getBoundingClientRect();
//let's save window size
var win = {
h : $(window).height(),
w : $(window).width()
};
//now we check against edges of element
//firstly we check one axis
//for example we check if left edge of element is between left and right edge of scree (still might be above/below)
var topEdgeInRange = box.top >= 0 && box.top <= win.h;
var bottomEdgeInRange = box.bottom >= 0 && box.bottom <= win.h;
var leftEdgeInRange = box.left >= 0 && box.left <= win.w;
var rightEdgeInRange = box.right >= 0 && box.right <= win.w;
//here we check if element is bigger then window and 'covers' the screen in given axis
var coverScreenHorizontally = box.left <= 0 && box.right >= win.w;
var coverScreenVertically = box.top <= 0 && box.bottom >= win.h;
//now we check 2nd axis
var topEdgeInScreen = topEdgeInRange && ( leftEdgeInRange || rightEdgeInRange || coverScreenHorizontally );
var bottomEdgeInScreen = bottomEdgeInRange && ( leftEdgeInRange || rightEdgeInRange || coverScreenHorizontally );
var leftEdgeInScreen = leftEdgeInRange && ( topEdgeInRange || bottomEdgeInRange || coverScreenVertically );
var rightEdgeInScreen = rightEdgeInRange && ( topEdgeInRange || bottomEdgeInRange || coverScreenVertically );
//now knowing presence of each edge on screen, we check if element is partially or entirely present on screen
var isPartiallyOnScreen = topEdgeInScreen || bottomEdgeInScreen || leftEdgeInScreen || rightEdgeInScreen;
var isEntirelyOnScreen = topEdgeInScreen && bottomEdgeInScreen && leftEdgeInScreen && rightEdgeInScreen;
return partial ? isPartiallyOnScreen : isEntirelyOnScreen;
};
$.expr.filters.onscreen = function(elem) {
return $(elem).isOnScreen(true);
};
$.expr.filters.entireonscreen = function(elem) {
return $(elem).isOnScreen(true);
};
use clear:left; or clear:both in your css.
#map { float:left; width:700px; height:500px; }
#list { float:left; width:200px; background:#eee; list-style:none; padding:0; }
#similar { float:left; width:200px; background:#000; clear:both; }
<div id="map"></div>
<ul id="list"></ul>
<div id ="similar">
this text should be below, not next to ul.
</div>
I had the same problem. I want to create custom result for my api controllers, to call them like
return Ok("some text");
Then i did this: 1) Create custom result type with singletone
public sealed class EmptyResult : IHttpActionResult
{
public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
{
return Task.FromResult(new HttpResponseMessage(System.Net.HttpStatusCode.NoContent) { Content = new StringContent("Empty result") });
}
}
2) Create custom controller with new method:
public class CustomApiController : ApiController
{
public IHttpActionResult EmptyResult()
{
return new EmptyResult();
}
}
And then i can call them in my controllers, like this:
public IHttpActionResult SomeMethod()
{
return EmptyResult();
}
DateTimeFormatter
has in-built formats that can directly be used to parse a character sequence. It is case Sensitive, Nov will work however nov and
NOV wont work:
DateTimeFormatter pattern = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
try {
LocalDate datetime = LocalDate.parse(oldDate, pattern);
System.out.println(datetime);
} catch (DateTimeParseException e) {
// DateTimeParseException - Text '2019-nov-12' could not be parsed at index 5
// Exception handling message/mechanism/logging as per company standard
}
DateTimeFormatterBuilder
provides custom way to create a formatter. It is Case Insensitive, Nov , nov and NOV will be treated as same.
DateTimeFormatter f = new DateTimeFormatterBuilder().parseCaseInsensitive()
.append(DateTimeFormatter.ofPattern("yyyy-MMM-dd")).toFormatter();
try {
LocalDate datetime = LocalDate.parse(oldDate, f);
System.out.println(datetime); // 2019-11-12
} catch (DateTimeParseException e) {
// Exception handling message/mechanism/logging as per company standard
}
use for loop. like this:
for x in [1,2,7,8,9,10,13,14,19,20,21,22]:
new_list.append(my_list[i + x])
Not sure if I understood correctly but here is snippet that I use to open links from Bootstrap tab menu:
<ul class="nav nav-tabs">
<li class="active"><a href="#foo" data-toggle="tab">Foo</a></li>
<li><a href="#bar" data-toggle="tab">Bar</a></li>
<li><a href="baz.html" class="external">Baz</a></li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="foo">Foo</div>
<div class="tab-pane" id="bar">Bar</div>
</div>
$('.nav a:not(".external")').click(function (e) {
e.preventDefault()
$(this).tab('show')
})
In the context of Drupal, the difference will depend whether clean URLs are on or not.
With them off, $_SERVER['REQUEST_URI']
will have the full path of the page as called w/ /index.php
, while $_GET["q"]
will just have what is assigned to q
.
With them on, they will be nearly identical w/o other arguments, but $_GET["q"]
will be missing the leading /
. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.
svn revert deletedDirectory
Here's the documentation for the svn revert
command.
If deletedDirectory
was deleted using rmdir
and not svn rm
, you'll need to do
svn update deletedDirectory
instead.
Just a minor addition: The speed difference between memcpy()
and std::copy()
can vary quite a bit depending on if optimizations are enabled or disabled. With g++ 6.2.0 and without optimizations memcpy()
clearly wins:
Benchmark Time CPU Iterations
---------------------------------------------------
bm_memcpy 17 ns 17 ns 40867738
bm_stdcopy 62 ns 62 ns 11176219
bm_stdcopy_n 72 ns 72 ns 9481749
When optimizations are enabled (-O3
), everything looks pretty much the same again:
Benchmark Time CPU Iterations
---------------------------------------------------
bm_memcpy 3 ns 3 ns 274527617
bm_stdcopy 3 ns 3 ns 272663990
bm_stdcopy_n 3 ns 3 ns 274732792
The bigger the array the less noticeable the effect gets, but even at N=1000
memcpy()
is about twice as fast when optimizations aren't enabled.
Source code (requires Google Benchmark):
#include <string.h>
#include <algorithm>
#include <vector>
#include <benchmark/benchmark.h>
constexpr int N = 10;
void bm_memcpy(benchmark::State& state)
{
std::vector<int> a(N);
std::vector<int> r(N);
while (state.KeepRunning())
{
memcpy(r.data(), a.data(), N * sizeof(int));
}
}
void bm_stdcopy(benchmark::State& state)
{
std::vector<int> a(N);
std::vector<int> r(N);
while (state.KeepRunning())
{
std::copy(a.begin(), a.end(), r.begin());
}
}
void bm_stdcopy_n(benchmark::State& state)
{
std::vector<int> a(N);
std::vector<int> r(N);
while (state.KeepRunning())
{
std::copy_n(a.begin(), N, r.begin());
}
}

You can create a defaultdict
from collections import defaultdict
d1 = defaultdict(int) # defaults to 0 values for keys
unq = set(lst1) # lst1 = [1, 2, 2, 3, 4, 1, 2, 7]
for each in unq:
d1[each] = lst1.count(each)
else:
print(d1)
To put a sequence or another numpy array into a numpy array, Just change this line:
kOUT=np.zeros(N+1)
to:
kOUT=np.asarray([None]*(N+1))
Or:

If you always add to the end, then each element will be added to the end and stay that way until you change it.
If you always insert at the start, then each element will appear in the reverse order you added them.
If you insert them in the middle, the order will be something else.
Of course that works; when @item1 = N''
, it IS NOT NULL
.
You can define @item1
as NULL
by default at the top of your stored procedure, and then not pass in a parameter.
Is it that
success()
returns earlier thancomplete()
?
Yes; the AJAX success()
method runs before the complete()
method.
Below is a diagram illustrating the process flow:
It is important to note that
The success()
(Local Event) is only called if the request was successful (no errors from the server, no errors with the data).
On the other hand, the complete()
(Local Event) is called regardless of if the request was successful, or not. You will always receive a complete callback, even for synchronous requests.
... more details on AJAX Events here.
Before understanding next
, you need to have a little idea of Request-Response cycle in node though not much in detail.
It starts with you making an HTTP request for a particular resource and it ends when you send a response back to the user i.e. when you encounter something like res.send(‘Hello World’);
let’s have a look at a very simple example.
app.get('/hello', function (req, res, next) {
res.send('USER')
})
Here we do not need next(), because resp.send will end the cycle and hand over the control back to the route middleware.
Now let’s take a look at another example.
app.get('/hello', function (req, res, next) {
res.send("Hello World !!!!");
});
app.get('/hello', function (req, res, next) {
res.send("Hello Planet !!!!");
});
Here we have 2 middleware functions for the same path. But you always gonna get the response from the first one. Because that is mounted first in the middleware stack and res.send will end the cycle.
But what if we always do not want the “Hello World !!!!” response back. For some conditions we may want the "Hello Planet !!!!" response. Let’s modify the above code and see what happens.
app.get('/hello', function (req, res, next) {
if(some condition){
next();
return;
}
res.send("Hello World !!!!");
});
app.get('/hello', function (req, res, next) {
res.send("Hello Planet !!!!");
});
What’s the next
doing here. And yes you might have gusses. It’s gonna skip the first middleware function if the condition is true and invoke the next middleware function and you will have the "Hello Planet !!!!"
response.
So, next pass the control to the next function in the middleware stack.
What if the first middleware function does not send back any response but do execute a piece of logic and then you get the response back from second middleware function.
Something like below:-
app.get('/hello', function (req, res, next) {
// Your piece of logic
next();
});
app.get('/hello', function (req, res, next) {
res.send("Hello !!!!");
});
In this case you need both the middleware functions to be invoked. So, the only way you reach the second middleware function is by calling next();
What if you do not make a call to next. Do not expect the second middleware function to get invoked automatically. After invoking the first function your request will be left hanging. The second function will never get invoked and you will not get back the response.
Using ant debug after building build.xml file :
in your cmd your root should be your project at first then use the ant debug command e.g:

As an alternate you can use reactive forms. Here is an example: https://stackblitz.com/edit/angular-pqb2xx

}
applyPriceToAll() {
const formLines = this.mainForm.get('orderLines') as FormArray;
const globalPrice = this.mainForm.get('globalPrice').value;
formLines.controls.forEach(control => control.get('price').setValue(globalPrice));
// optionally recheck value and validity without emit event.
}
submitForm() {

C++ does not have the for_each
loop feature in its syntax. You have to use c++11 or use the template function std::for_each
.
struct Function {
int input;
Function(int input): input(input) {}
void operator()(Attack& attack) {
if(attack->m_num == input) attack->makeDamage();
}
};
Function f(input);
std::for_each(m_attack.begin(), m_attack.end(), f);
My use case was only to set the value of a local variable.
Personally I found the try and except style cleaner to read
items = [10, 20]
try: first_item = items[0]
except IndexError: first_item = None
print first_item
than slicing a list.
items = [10, 20]
first_item = (items[:1] or [None, ])[0]
print first_item
You could also do this to make it more dynamic.
<input name="filterByPolarity" data-ng-model="text.polarity"/>
Then you ng-repeat will look like this
<div class="tweet" data-ng-repeat="tweet in tweets | filter:text"></div>
This filter will of course only be used to filter by polarity
Once you have detected the bounding box of the document, you can perform a four-point perspective transform to obtain a top-down birds eye view of the image. This will fix the skew and isolate only the desired object.
Input image:
Detected text object
Top-down view of text document
Code
from imutils.perspective import four_point_transform
import cv2
import numpy
# Load image, grayscale, Gaussian blur, Otsu's threshold
image = cv2.imread("1.png")
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray, (7,7), 0)
thresh = cv2.threshold(blur, 0, 255, cv2.THRESH_BINARY + cv2.THRESH_OTSU)[1]
# Find contours and sort for largest contour
cnts = cv2.findContours(thresh, cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_SIMPLE)
cnts = cnts[0] if len(cnts) == 2 else cnts[1]
cnts = sorted(cnts, key=cv2.contourArea, reverse=True)
displayCnt = None
for c in cnts:
# Perform contour approximation
peri = cv2.arcLength(c, True)
approx = cv2.approxPolyDP(c, 0.02 * peri, True)
if len(approx) == 4:
displayCnt = approx
break
# Obtain birds' eye view of image
warped = four_point_transform(image, displayCnt.reshape(4, 2))
cv2.imshow("thresh", thresh)
cv2.imshow("warped", warped)
cv2.imshow("image", image)
cv2.waitKey()
be sure, that if the declarations for the pipe are done in one module, while you are using the pipe inside another module, you should provide correct imports/declarations at the current module under which is the class where you are using the pipe. In my case that was the reason for the pipe miss
You misspelled permission
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
file_name=test.log
# set first K lines:
K=1000
# line count (N):
N=$(wc -l < $file_name)
# length of the bottom file:
L=$(( $N - $K ))
# create the top of file:
head -n $K $file_name > top_$file_name
# create bottom of file:
tail -n $L $file_name > bottom_$file_name
Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so
split -l 300000 file_name
will output xaa
with 300k lines and xab
with 100k lines, for an input with 400k lines.
Even though this is old and answered, i´d like to share the solution i made out of it 2020
it comes with the flexibility to run at anytime and run a callback if greater and or smaller the specified mbps
you can start the test anywhere after you included the testConnectionSpeed Object by running the testConnectionSpeed.run(mbps, morefunction, lessfunction)
for example:
var testConnectionSpeed = {
imageAddr : "https://upload.wikimedia.org/wikipedia/commons/a/a6/Brandenburger_Tor_abends.jpg", // this is just an example, you rather want an image hosted on your server
downloadSize : 2707459, // this must match with the image above
run:function(mbps_max,cb_gt,cb_lt){
testConnectionSpeed.mbps_max = parseFloat(mbps_max) ? parseFloat(mbps_max) : 0;
testConnectionSpeed.cb_gt = cb_gt;
testConnectionSpeed.cb_lt = cb_lt;
testConnectionSpeed.InitiateSpeedDetection();
},
InitiateSpeedDetection: function() {
window.setTimeout(testConnectionSpeed.MeasureConnectionSpeed, 1);
},
result:function(){
var duration = (endTime - startTime) / 1000;
var bitsLoaded = testConnectionSpeed.downloadSize * 8;

I used this successfuly to load lowres media for slow internet connections. You have to play around a bit because on the one hand, the larger the image, the more reasonable the test, on the other hand the test will take way much longer for slow connection and in my case I especially did not want slow connection users to load lots of MBs.
Use CurrPorts (it's free and no-install): http://www.nirsoft.net/utils/cports.html
/close <Local Address> <Local Port> <Remote Address> <Remote Port> {Process Name}
Examples:
# Close all connections with remote port 80 and remote address 192.168.1.10:
/close * * 192.168.1.10 80
# Close all connections with remote port 80 (for all remote addresses):
/close * * * 80
# Close all connections to remote address 192.168.20.30:
/close * * 192.168.20.30 *
# Close all connections with local port 80:
/close * 80 * *
# Close all connections of Firefox with remote port 80:
/close * * * 80 firefox.exe
It also has a nice GUI with search and filter features.
Note: This answer is huntharo and JasonXA's answer and comment put together and simplified to make it easier for readers. Examples come from CurrPorts' web page.
>>> x = arange(20).reshape(4,5)
>>> x array([[ 0, 1, 2, 3, 4],
[ 5, 6, 7, 8, 9],
[10, 11, 12, 13, 14],
[15, 16, 17, 18, 19]])
if you want the second column you can use
>>> x[:, 1]
array([ 1, 6, 11, 16])
Here's the solution I came up with:
select FIELD from TABLE where FIELD > LASTVAL order by FIELD fetch first N rows only;
By initializing LASTVAL to 0 (or '' for a text field), then setting it to the last value in the most recent set of records, this will step through the table in chunks of N records.
Your code: path = ActiveWorkbook.Path
returns blank because you haven't saved your workbook yet.
To overcome your problem, go back to the Excel sheet, save your sheet, and run your code again.
This time it will not show blank, but will show you the path where it is located (current folder)
I hope that helped.
I ran in to the same issue even though i selected "Trust this computer" option first time.
This worked for me
Try this. I am using Jupyter notebook (OS: Ubuntu 16.04 LTS on Google Cloud Platform + on Windows). Executed following command in the Jupyter notebook to install opencv:
!pip install opencv-contrib-python #working on both Windows and Ubuntu
After successful installation you will get following message:
Successfully installed opencv-contrib-python-4.1.0.25
Now restart the kernel and try to import opencv as:
import cv2
The same command can be used to installed opencv on Windows as well.
SOLUTION 2: try following commands to install opencv: For Ubuntu: Run following command from terminal:
sudo apt-get install libsm6 libxrender1 libfontconfig1
Restart Jupyter notebook kernel and execute following command:
!pip install opencv-contrib-python
NOTE: You can run all the above commands from the terminal as well without using '!'.
If you run your playbook with ansible-playbook -vvv
you'll see the actual command being run, so you can check whether the key is actually being included in the ssh command (and you might discover that the problem was the wrong username rather than the missing key).
I agree with Brian's comment above (and zigam's edit) that the vars section is too late. I also tested including the key in the on-the-fly definition of the host like this
# fails
- name: Add all instance public IPs to host group
add_host: hostname={{ item.public_ip }} groups=ec2hosts ansible_ssh_private_key_file=~/.aws/dev_staging.pem
loop: "{{ ec2.instances }}"
but that fails too.
So this is not an answer. Just some debugging help and things not to try.
Use TimeSpan.Parse
to convert the string
http://msdn.microsoft.com/en-us/library/system.timespan.parse(v=vs.110).aspx
you can convert the integer dataframe into string first and then do the operation e.g.
df3['nID']=df3['nID'].astype(str)
grp = df3.groupby('userID')['nID'].aggregate(lambda x: '->'.join(tuple(x)))
You can also use AppCompatSpinner widget:
<android.support.v7.widget.AppCompatSpinner
android:id="@+id/spinner_order_type"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:backgroundTint="@color/red"/>
Inside your Activity class:
AppCompatSpinner spinOrderType = (AppCompatSpinner) findViewById(R.id.spinner_order_type);
List<String> categories = new ArrayList<String>();
categories.add(getString(R.string.label_table_order));
categories.add(getString(R.string.label_take_away));
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(mContext,
R.layout.layout_spinner_item, categories);
dataAdapter.setDropDownViewResource(R.layout.layout_spinner_item);
spinOrderType.setAdapter(dataAdapter);
spinOrderType.setSelection(0);
spinOrderType.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long l) {
String item = parent.getItemAtPosition(position).toString();
Log.d(TAG, item);
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
layout_spinner_item.xml
<?xml version="1.0" encoding="utf-8"?>

Regular expressions allow for everything that LIKE
allows for, and much more, but have a completely different syntax. However, since the rules for LIKE
are so simple(where %
means zero-or-more characters and _
means one character), and both LIKE
arguments and regular expressions are expressed in strings, we can create a regular expression that takes a LIKE
argument (e.g. abc_ef% *usd
) and turn it into the equivalent regular expression (e.g. \Aabc.ef.* \*usd\z
):
@"\A" + new Regex(@"\.|\$|\^|\{|\[|\(|\||\)|\*|\+|\?|\\").Replace(toFind, ch => @"\" + ch).Replace('_', '.').Replace("%", ".*") + @"\z"
From that we can build a Like()
method:
public static class MyStringExtensions
{
public static bool Like(this string toSearch, string toFind)
{
return new Regex(@"\A" + new Regex(@"\.|\$|\^|\{|\[|\(|\||\)|\*|\+|\?|\\").Replace(toFind, ch => @"\" + ch).Replace('_', '.').Replace("%", ".*") + @"\z", RegexOptions.Singleline).IsMatch(toSearch);
}
}
And hence:
bool willBeTrue = "abcdefg".Like("abcd_fg");
bool willAlsoBeTrue = "abcdefg".Like("ab%f%");
bool willBeFalse = "abcdefghi".Like("abcd_fg");
I came across this question as I had exact same problem. Although accepted answer works good but with matplotlib version 2.1.0
, it is pretty straight forward to have two scatter plots in one plot without using a reference to Axes
import matplotlib.pyplot as plt
plt.scatter(x,y, c='b', marker='x', label='1')
plt.scatter(x, y, c='r', marker='s', label='-1')
plt.legend(loc='upper left')
plt.show()
df = pd.read_csv('filename.csv', sep='\t', header=0)
You can load the tsv file directly into pandas data frame by specifying delimitor and header.
This is using what leech talked about, but making it work for IE (IE doesn't support matches):
function closest(el, selector, stopSelector) {
var retval = null;
while (el) {
if (el.className.indexOf(selector) > -1) {
retval = el;
break
} else if (stopSelector && el.className.indexOf(stopSelector) > -1) {
break
}
el = el.parentElement;
}
return retval;
}
It's not perfect, but it works if the selector is unique enough so it won't accidentally match the incorrect element.
please, something went xxx*x, and that's not true at all, check that

In Python 3, ConfigParser
has been renamed to configparser
for PEP 8 compliance. It looks like the package you are installing does not support Python 3.
Well, first you need to request the username of the user from the session in your controller action like this:
$username=$this->get('security.context')->getToken()->getUser()->getUserName();
then do a query to the db and get your object with regular dql like
$em = $this->get('doctrine.orm.entity_manager');
"SELECT u FROM Acme\AuctionBundle\Entity\User u where u.username=".$username;
$q=$em->createQuery($query);
$user=$q->getResult();
the $user should now hold the user with this username ( you could also use other fields of course)
...but you will have to first configure your /app/config/security.yml configuration to use the appropriate field for your security provider like so:
security:
provider:
example:
entity: {class Acme\AuctionBundle\Entity\User, property: username}
hope this helps!
Adding up to what Micheal has said:
You can use Predicate as follows in filtering collections in java:
public static <T> Collection<T> filter(final Collection<T> target,
final Predicate<T> predicate) {
final Collection<T> result = new ArrayList<T>();
for (final T element : target) {
if (predicate.apply(element)) {
result.add(element);
}
}
return result;
}
one possible predicate can be:
final Predicate<DisplayFieldDto> filterCriteria =
new Predicate<DisplayFieldDto>() {
public boolean apply(final DisplayFieldDto displayFieldDto) {
return displayFieldDto.isDisplay();
}
};
Usage:
final List<DisplayFieldDto> filteredList=
(List<DisplayFieldDto>)filter(displayFieldsList, filterCriteria);
Take care about your angular version, if you work under angular 2.x.x so maybe you need to upgrade to angular 4.x.x
Some dependencies needs angular 4
Here is a tutorial for how to install angular 4 or update your project.
They sound about the same, however, the exit() also allows you to set the exit code of your PHP script.
Usually you don't really need this, but when writing console PHP scripts, you might want to check with for example Bash if the script completed everything in the right way.
Then you can use exit() and catch that later on. Die() however doesn't support that.
Die() always exists with code 0. So essentially a die() command does the following:
<?php
echo "I am going to die";
exit(0);
?>
Which is the same as:
<?php
die("I am going to die");
?>
It's all about a lazy approach to the evaluation and some extra optimization of range
.
Values in ranges don't need to be computed until real use, or even further due to extra optimization.
By the way, your integer is not such big, consider sys.maxsize
sys.maxsize in range(sys.maxsize)
is pretty fast
due to optimization - it's easy to compare given integer just with min and max of range.
but:
Decimal(sys.maxsize) in range(sys.maxsize)
is pretty slow.
(in this case, there is no optimization in range
, so if python receives unexpected Decimal, python will compare all numbers)
You should be aware of an implementation detail but should not be relied upon, because this may change in the future.
This is discouraged (if you want to create/distribute a clean Docker image), since the PATH
variable is set by /etc/profile
script, the value can be overridden.
head /etc/profile
:
if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH
At the end of the Dockerfile, you could add:
RUN echo "export PATH=$PATH" > /etc/environment
So PATH is set for all users.

And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.
User Control with jQuery Inside an UpdatePanel
This isn't a direct answer to the question, but I did put this solution together by reading the answers that I found here, and I thought someone might find it useful.
I was trying to use a jQuery textarea limiter inside of a User Control. This was tricky, because the User Control runs inside of an UpdatePanel, and it was losing its bindings on callback.
If this was just a page, the answers here would have applied directly. However, User Controls do not have direct access to the head tag, nor did they have direct access to the UpdatePanel as some of the answers assume.
I ended up putting this script block right into the top of my User Control's markup. For the initial bind, it uses $(document).ready, and then it uses prm.add_endRequest from there:
<script type="text/javascript">
function BindControlEvents() {
//jQuery is wrapped in BindEvents function so it can be re-bound after each callback.
//Your code would replace the following line:
$('#<%= TextProtocolDrugInstructions.ClientID %>').limit('100', '#charsLeft_Instructions');
}
//Initial bind
$(document).ready(function () {
BindControlEvents();
});
//Re-bind for callbacks
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function() {
BindControlEvents();
});
</script>
So... Just thought someone might like to know that this works.
"fb://page/
does not work with newer versions of the FB app. You should use fb://facewebmodal/f?href=
for newer versions.
This is a full fledged working code currently live in one of my apps:
public static String FACEBOOK_URL = "https://www.facebook.com/YourPageName";
public static String FACEBOOK_PAGE_ID = "YourPageName";
//method to get the right URL to use in the intent
public String getFacebookPageURL(Context context) {
PackageManager packageManager = context.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) { //newer versions of fb app
return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
} else { //older versions of fb app
return "fb://page/" + FACEBOOK_PAGE_ID;
}
} catch (PackageManager.NameNotFoundException e) {
return FACEBOOK_URL; //normal web url
}
}
This method will return the correct url for app if installed or web url if app is not installed.
Then start an intent as follows:
Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = getFacebookPageURL(this);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);
That's all you need.

You can create a extension method:
public static IEnumerable<T> Do<T>(this IEnumerable<T> self, Action<T> action) {
foreach(var item in self) {
action(item);
yield return item;
}
}
And then use it in code:
listofCompany.Do(d=>d.Id = 1);
listofCompany.Where(d=>d.Name.Contains("Inc")).Do(d=>d.Id = 1);
I had to terminate activeMQ java process among many java processes on the server, and this one is started by the specific user (username is activemq). So good way of separating may be to start a process by a specific user :
ps -ef | grep "activemq" | awk '{print $2}' | xargs kill -9
x:Name
means: create a field in the code behind to hold a reference to this object.
Name
means: set the name property of this object.
I run into this problem on a regular basis and often use the "add a method" solution. However, there are definitely cases where "add a method" or "compute it in the view" don't work (or don't work well). E.g. when you are caching template fragments and need some non-trivial DB computation to produce it. You don't want to do the DB work unless you need to, but you won't know if you need to until you are deep in the template logic.
Some other possible solutions:
Use the {% expr <expression> as <var_name> %} template tag found at http://www.djangosnippets.org/snippets/9/ The expression is any legal Python expression with your template's Context as your local scope.
Change your template processor. Jinja2 (http://jinja.pocoo.org/2/) has syntax that is almost identical to the Django template language, but with full Python power available. It's also faster. You can do this wholesale, or you might limit its use to templates that you are working on, but use Django's "safer" templates for designer-maintained pages.
Found this absolute hack that actually works quite well:
https://codepen.io/nikitahl/pen/vyZbwR
Not CSS only though.
The basic gist is to have a container on the dropdown, .select-container
in this case. That container has it's ::before
set up to display content
based on its data-content
attribute/dataset, along with all of the overflow:hidden; text-overflow: ellipsis;
and sizing necessary to make the ellipsis work.
When the select changes, javascript assigns the value (or you could retrieve the text of the option out of the select.options
list) to the dataset.content of the container, and voila!

So I worked out at the end that you cannot uninstall 3.4 as it is default on Ubuntu.
All I did was simply remove Jupyter
and then alias python=python2.7
and install all packages on Python 2.7 again.
Arguably, I can install virtualenv
but me and my colleagues are only using 2.7. I am just going to be lazy in this case :)
What could be the possible cause of this exception?
You may not have appropriate Jar in your class path.
How it could be removed?
By putting HTTPClient jar in your class path. If it's a webapp, copy Jar into WEB-INF/lib
if it's standalone, make sure you have this jar in class path or explicitly set using -cp
option
as the doc says,
Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.
The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

var list ={}; var count= Object.keys(list).length;
I think what you are looking for is as follows.
cars_by_cylinders_gears <- mtcars %>%
group_by(cyl, gear) %>%
summarise(count = n())
This is using the dplyr package. This is essentially the longhand version of the count () solution provided by docendo discimus.
The config file is just an XML file, you can open it by:
private static XmlDocument loadConfigDocument()
{
XmlDocument doc = null;
try
{
doc = new XmlDocument();
doc.Load(getConfigFilePath());
return doc;
}
catch (System.IO.FileNotFoundException e)
{
throw new Exception("No configuration file found.", e);
}
catch (Exception ex)
{
return null;
}
}
and later retrieving values by:
// retrieve appSettings node
XmlNode node = doc.SelectSingleNode("//appSettings");
Aggregate classes, like A in your example(*), must have their members public, and have no user-defined constructors. They are intialized with initializer list, e.g. A a {0,0};
or in your case B() : A({0,0}){}
. The members of base aggregate class cannot be individually initialized in the constructor of the derived class.
(*) To be precise, as it was correctly mentioned, original class A
is not an aggregate due to private non-static members
I'm using contentEditable
to allow rich text editing in my app. I don't know how it slips through, but when an image is inserted, and then resized (by dragging the anchors on its side), it generates something like this:
<img style="width:55px;height:55px" width="100" height="100" src="pic.gif" border=0/>
(subsequent testing shown that inserted images did not contain this "rogue" style attr+param).
When rendered by the browser (IE7), the width and height in the style overrides the img width/height param (so the image is shown like how I wanted it.. resized to 55px x 55px. So everything went well so it seems.
When I output the page to a ms-word document via setting the mime type application/msword or pasting the browser rendering to msword document, all the images reverted back to its default size. I finally found out that msword is discarding the style and using the img width and height tag (which has the value of the original image size).
Took me a while to found this out. Anyway... I've coded a javascript function to traverse all tags and "transferring" the img style.width and style.height values into the img.width and img.height, then clearing both the values in style, before I proceed saving this piece of html/richtext data into the database.
cheers.
opps.. my answer is.. no. leave both attributes directly under img, rather than style.
None of the other solutions worked for me.
However, adding this to my package.json fixed the issue for me:
"resolutions": {
"react-dev-utils": "10.0.0"
},
This is not possible as of May 2017, because Postman only works with HTTP methods such as POST, GET, PUT, DELETE.
P/S: There is a request for this if you want to upvote: github.com/postmanlabs/postman-app-support/issues/4009
In the Divi Theme Documentation, it says that the theme comes with access to 'ePanel' which also has an 'Integration' section.
You should be able to add this code:
<script>
$( ".et-pb-icon" ).click(function() {
$( this ).toggleClass( "active" );
});
</script>
into the the box that says 'Add code to the head of your blog' under the 'Integration' tab, which should get the jQuery working.
Then, you should be able to style your class to what ever you need.
Just my two cents:
My scenario:
Solution:
To get around this i just provided more explicit parameters:
Add-Migration -ConnectionString "Server=localhost\SQLEXPRESS;Database=YourDataBase;Trusted_Connection=True;" -ConnectionProviderName "System.Data.SqlClient" -verbose
I am lead to believe that you can set a setting in your app.config folder to allow you to default this behaviour so you don't have to provide explicit parameters everytime. However I am not sure on how to do this.
<div class="preload">

if you happen to not have a graphical interface available you can also print out the commit graph on the command line:
git log --oneline --graph --decorate --all
if this command complains with an invalid option --oneline, use:
git log --pretty=oneline --graph --decorate --all
Simply select the class, right click and choose rename (probably F2 will also do). You can also select the class name in the source file, right click, choose Source, Refactor and rename. In both cases, both the class and the filename will be changed.
Quick solution: set PYTHONHOME and PYTHONPATH and include PYTHONHOME on PATH
For example if you installed to c:\Python27
set PYTHONHOME=c:\Python27
set PYTHONPATH=c:\Python27\Lib
set PATH=%PYTHONHOME%;%PATH%
Make sure you don't have a trailing '\' on the PYTHON* vars, this seems to break it aswel.
There are some options to do that.
One would be:
document.write(produceMessage())
Other would be appending some element in your document this way:
var span = document.createElement("span");
span.appendChild(document.createTextNode(produceMessage()));
document.body.appendChild(span);
Or just:
document.body.appendChild(document.createTextNode(produceMessage()));
If you're using jQuery, you can do this:
$(document.body).append(produceMessage());
I'm on Angular 6, Typescript 2.7, and I'm using Jest framework to unit test.
I had @types/jest
installed and added on typeRoots
inside tsconfig.json
But still have the display error below (i.e: on terminal there is no errors)
cannot find name describe
And adding the import :
import {} from 'jest'; // in my case or jasmine if you're using jasmine
doesn't technically do anything, so I thought, that there is an import somewhere causing this problem, then I found, that if delete the file
tsconfig.spec.json
in the src/
folder, solved the problem for me. As @types is imported before inside the rootTypes.
I recommend you to do same and delete this file, no needed config is inside. (ps: if you're in the same case as I am)
To add the privileges needed to the files add and grant right to the following local user: SQLServerMSSQLUser$COMPUTERNAME$INSTANCENAME, where COMPUTERNAME and INSTANCENAME has to be replaced with name of computer and MSSQL instance respectively.
From now you can also :
Action<int> action = (o) => Thread.Sleep(o);
int param = 10;
await new TaskFactory().StartNew(action, param)
This works for me with org.springframework.jdbc-3.0.6.RELEASE.jar. I could not find this anywhere in the Spring docs (maybe I'm just lazy) but I found (trial and error) that the TRACE level did the magic.
I'm using log4j-1.2.15 along with slf4j (1.6.4) and properties file to configure the log4j:
log4j.logger.org.springframework.jdbc.core = TRACE
This displays both the SQL statement and bound parameters like this:
Executing prepared SQL statement [select HEADLINE_TEXT, NEWS_DATE_TIME from MY_TABLE where PRODUCT_KEY = ? and NEWS_DATE_TIME between ? and ? order by NEWS_DATE_TIME]
Setting SQL statement parameter value: column index 1, parameter value [aaa], value class [java.lang.String], SQL type unknown
Setting SQL statement parameter value: column index 2, parameter value [Thu Oct 11 08:00:00 CEST 2012], value class [java.util.Date], SQL type unknown
Setting SQL statement parameter value: column index 3, parameter value [Thu Oct 11 08:00:10 CEST 2012], value class [java.util.Date], SQL type unknown
Not sure about the SQL type unknown but I guess we can ignore it here
For just an SQL (i.e. if you're not interested in bound parameter values) DEBUG
should be enough.
Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".
TryGetValue is slightly faster, because FindEntry will only be called once.
How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.
FYI: It's not actually catching an error.
It's calling:
public bool TryGetValue(TKey key, out TValue value)
{
int index = this.FindEntry(key);
if (index >= 0)
{
value = this.entries[index].value;
return true;
}
value = default(TValue);
return false;
}
ContainsKey is this:
public bool ContainsKey(TKey key)
{
return (this.FindEntry(key) >= 0);
}
My problem was my user's folder had a space in folder name.
After creating a new user and switching to that windows user, windows shortcuts and links from within' Anaconda worked fine.
Windows 8.1 64 Bit. Latest Anaconda.
Note: I ended up uninstalling an reinstalling Anaconda but my sense is the problem was really just the space in the windows user username/user folder.
We can use data.table to get it quickly. First create df without factors,
df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)), stringsAsFactors=F)
Now you can use
setDT(df)
for (jj in 1:ncol(df)) set(df, i = which(df[[jj]]==""), j = jj, v = NA)
and you can convert it back to a data.frame
setDF(df)
If you only want to use data.frame and keep factors it's more difficult, you need to work with
levels(df$value)[levels(df$value)==""] <- NA
where value is the name of every column. You need to insert it in a loop.
The two code segments work the same. However, unsigned int" route is correct. Using unsigned int types will work better with the vector in the instance you used it. Calling the size() member function on a vector returns an unsigned integer value, so you want to be comparing the variable "i" to a value of its own type.
Also, if you are still a little uneasy about how "unsigned int" looks in your code, try "uint". This is basically a shortened version of "unsigned int" and it works exactly the same. You also don't need to include other headers to use it.

a side note: Javascript Cryptography considered harmful. Worth the read.
Another way with an Advanced xsd to c# classes generation Tools : xsd2code.com. This tool is very handy and powerfull. It has a lot more customisation than the xsd.exe tool from Visual Studio. Xsd2Code++ can be customised to use Lists or Arrays and supports large schemas with a lot of Import statements.
Note of some features,
You could try this:
- Open the Terminal application. It can be found in the Utilities directory inside the Applications directory.
- Type the following: echo 'export PATH=YOURPATHHERE:$PATH' >> ~/.profile, replacing "YOURPATHHERE" with the name of the directory you want to add. Make certain that you use ">>" instead of one ">".
- Hit Enter.
- Close the Terminal and reopen. Your new Terminal session should now use the new PATH.
Another option to all of the good answers here is the npm package react-google-font-loader
, found here.
The usage is simple:
import GoogleFontLoader from 'react-google-font-loader';
// Somewhere in your React tree:
<GoogleFontLoader
fonts={[
{
font: 'Bungee Inline',
weights: [400],
},
]}
/>
Then you can just use the family name in your CSS:
body {
font-family: 'Bungee Inline', cursive;
}
Disclaimer: I'm the author of the react-google-font-loader
package.
You can also use the Cast() operation :
Declare @name varchar(100);
set @name='....';
Select Cast(@name as varchar(10)) as new_name
That's the way to create complex boolean expressions: combine them with AND and OR. The snippet you posted doesn't throw any error for the IF.
If you don't have access to shared hosting - the final IIS instance. You can create a HttpModule
that gets added this code to every HttpApplication.Begin_Request
event:-
HttpContext context = HttpContext.Current;
context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);
HttpContext.Current.Response.AppendHeader("Content-encoding", "gzip");
HttpContext.Current.Response.Cache.VaryByHeaders["Accept-encoding"] = true;
Just change the width of the input. Around 90px
<input type="file" style="width: 90px" />
<img id="instapic01" class="samples" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"/>
You can initialize it just like any list:
public List<ContactNumber> ContactNumbers { get; set; }
public Human(int id)
{
Id = id;
ContactNumbers = new List<ContactNumber>();
}
public Human(int id, string address, string name) :this(id)
{
Address = address;
Name = name;
// no need to initialize the list here since you're
// already calling the single parameter constructor
}
However, I would even go a step further and make the setter private since you often don't need to set the list, but just access/modify its contents:
public List<ContactNumber> ContactNumbers { get; private set; }

$('*[data-customerID="22"]');
You should be able to omit the *
, but if I recall correctly, depending on which jQuery version you’re using, this might give faulty results.
Note that for compatibility with the Selectors API (document.querySelector{,all}
), the quotes around the attribute value (22
) may not be omitted in this case.
Also, if you work with data attributes a lot in your jQuery scripts, you might want to consider using the HTML5 custom data attributes plugin. This allows you to write even more readable code by using .dataAttr('foo')
, and results in a smaller file size after minification (compared to using .attr('data-foo')
).
Having the developer code signing id is correct for sure, but also make sure you device is added to the Member Center via organizer, or through the developer portal.
A few days ago I reset my device list, and today I was suddenly getting this for an iPod I debug with all the time. About 15 mins later I realized the problem.
One could view the (additional) include path for a C program from bash by checking out the following:
echo $C_INCLUDE_PATH
If this is empty, it could be modified to add default include locations, by:
export C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/include
try
{
$conn = new PDO("sqlsrv:Server=$server_name;Database=$db_name;ConnectionPooling=0", "", "");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
$e->getMessage();
}
Add:
display: inline-block;
to the style of your td
.
Add:
display: inline-block;
word-break: break-word;
to the style of your td
.
Note:
Mind that, as for now, break-word
is not part of the standard specification for webkit; therefore, you might be interested in employing the break-all
instead. This alternative value provides a undoubtedly drastic solution; however, it conforms to the standard.
Add:
display: inline-block;
word-break: break-word;
to the style of your td
.
The previous paragraph applies to Opera in a similar way.

Try this
Get-ChildItem | % { Write-Host "$($_.FullName)\$buildConfig\$($_.Name).dll" }
In your code,
$build-Config
is not a valid variable name. $.FullName
should be $_.FullName
$
should be $_.Name
You should take it simple here you go :
first you have the initial position of your text or button :
<div style="background-color:green; height:200px; width:400px; margin:0 0 0 35%;">
<h2> Simple Text </h2>
<div>
<button> Simple Button </button>
</div>
</div>
By adding this css code line to the h2 tag or to the div tag that holds the button tag
style:" text-align:center; "
Finaly The result code will be :
<div style="background-color:green; height:200px; width:400px; margin:0 0 0 35%;">
<h2 style="text-align:center;"> Simple Text </h2> <!-- <<--- here the changes -->
<div style="text-align:center"> <!-- <<--- here the changes -->
<button> Simple Button </button>
</div>
</div>
You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.
So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filter

For C# NUnit, you need to convert WebDriver to JSExecuter and then execute the script to check if document.ready state is complete or not. Check below code for reference:
public static void WaitForLoad(IWebDriver driver)
{
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
int timeoutSec = 15;
WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0, 0, timeoutSec));
wait.Until(wd => js.ExecuteScript("return document.readyState").ToString() == "complete");
}
This will wait until the condition is satisfied or timeout.
App server PermGen errors that happen after multiple deployments are most likely caused by references held by the container into your old apps' classloaders. For example, using a custom log level class will cause references to be held by the app server's classloader. You can detect these inter-classloader leaks by using modern (JDK6+) JVM analysis tools such as jmap and jhat to look at which classes continue to be held in your app, and redesigning or eliminating their use. Usual suspects are databases, loggers, and other base-framework-level libraries.
See Classloader leaks: the dreaded "java.lang.OutOfMemoryError: PermGen space" exception, and especially its followup post.
In my case, a script was running command while redirecting both stdout and stderr to a file, something like:
cmd > log 2>&1
I needed to update it such that when there is a failure, take some actions based on the error messages. I could of course remove the dup 2>&1
and capture the stderr from the script, but then the error messages won't go into the log file for reference. While the accepted answer from @lhunath is supposed to do the same, it redirects stdout
and stderr
to different files, which is not what I want, but it helped me to come up with the exact solution that I need:
(cmd 2> >(tee /dev/stderr)) > log
With the above, log will have a copy of both stdout
and stderr
and I can capture stderr
from my script without having to worry about stdout
.
If you use a Language Resource file to set the labels in your application you need to set the its value:
CultureInfo customCulture = new CultureInfo("en-US");
Languages.Culture = customCulture;
Noone cand read the file except for those who have access to the file. You must make the code readable (but not writable) by the web server. If the php code handler is running properly you can't read it by requesting by name from the web server.
If someone compromises your server you are at risk. Ensure that the web server can only write to locations it absolutely needs to. There are a few locations under /var which should be properly configured by your distribution. They should not be accessible over the web. /var/www should not be writable, but may contain subdirectories written to by the web server for dynamic content. Code handlers should be disabled for these.
Ensure you don't do anything in your php code which can lead to code injection. The other risk is directory traversal using paths containing .. or begining with /. Apache should already be patched to prevent this when it is handling paths. However, when it runs code, including php, it does not control the paths. Avoid anything that allows the web client to pass a file path.
Other answers work, but

$("select[name='CCards'] option:selected")
should do the trick
See jQuery documentation for more detail: http://api.jquery.com/selected-selector/

jquery method:
$("select[name='CCards'] option:selected").index()
Simply declare your variable outside any function:
globalValue = 1
def f(x):

If you need to assign to the global from within the function, use the global
statement:
def f(x):
global globalValue
print(globalValue + x)
globalValue += 1
The range()
function in python is a way to generate a sequence. Sequences are objects that can be indexed, like lists, strings, and tuples. An easy way to check for a sequence is to try retrieve indexed elements from them. It can also be checked using the Sequence Abstract Base Class(ABC)
from the collections module.
from collections import Sequence as sq
isinstance(foo, sq)
The range()
takes three arguments start
, stop
and step
.
start
: The staring element of the required sequencestop
: (n+1)th element of the required sequencestep
: The required gap between the elements of the sequence. It is an optional parameter that defaults to 1.To get your desired result you can make use of the below syntax.
range(1,c+1,2)
use this : export MYVAR="$(dirname "$(dirname "$(dirname "$(dirname $PWD)")")")"
if you want 4th parent directory
export MYVAR="$(dirname "$(dirname "$(dirname $PWD)")")"
if you want 3rd parent directory
export MYVAR="$(dirname "$(dirname $PWD)")"
if you want 2nd parent directory
This will find the largest file or folder in your present working directory:

Explain why the following code displays 2.5
instead of 3
:
$a = 012;
echo $a / 4;
Answer: When a number is preceded by a 0
in PHP, the number is treated as an octal number (base-8). Therefore the octal number 012
is equal to the decimal number 10
.
The short answer: Use utf8mb4
in 4 places:
SET NAMES utf8mb4
or something equivalent when establishing the client's connection to MySQLCHARACTER SET utf8mb4
on all tables/columns -- except columns that are strictly ascii/hex/country_code/zip_code/etc.<meta charset charset=UTF-8>
if you are outputting to HTML. (Yes the spelling is different here.)The above links provide the "detailed canonical answer is required to address all the concerns". -- There is a space limit on this forum.
Edit
In addition to CHARACTER SET utf8mb4
containing "all" the world's characters, COLLATION utf8mb4_unicode_520_ci
is arguable the 'best all-around' collation to use. (There are also Turkish, Spanish, etc, collations for those who want the nuances in those languages.)
Take the attribute
app:layout_behavior="@string/appbar_scrolling_view_behavior"
off the RecyclerView
and put it on the FrameLayout
that you are trying to show under the Toolbar
.
I've found that one important thing the scrolling view behavior does is to layout the component below the toolbar. Because the FrameLayout
has a descendant that will scroll (RecyclerView
), the CoordinatorLayout
will get those scrolling events for moving the Toolbar
.
One other thing to be aware of: That layout behavior will cause the FrameLayout
height to be sized as if the Toolbar
is already scrolled, and with the Toolbar
fully displayed the entire view is simply pushed down so that the bottom of the view is below the bottom of the CoordinatorLayout
.
This was a surprise to me. I was expecting the view to be dynamically resized as the toolbar is scrolled up and down. So if you have a scrolling component with a fixed component at the bottom of your view, you won't see that bottom component until you have fully scrolled the Toolbar
.
So when I wanted to anchor a button at the bottom of the UI, I worked around this by putting the button at the bottom of the CoordinatorLayout
(android:layout_gravity="bottom"
) and adding a bottom margin equal to the button's height to the view beneath the toolbar.
You can determine if as certain word is found in a cell by using
If InStr(cell.Value, "Word1") > 0 Then
If Word1 is found in the string the InStr()
function will return the location of the first character of Word1 in the string.
you can just get the pos
that you get from the onItemClick
and do:
listView.setItemChecked(pos, false);
that's the best way i know of
In MVC 3 I had to add:
using System.ComponentModel.DataAnnotations;
among usings when adding properties:
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
Especially if you are adding these properties in .edmx file like me. I found that by default .edmx files don't have this using so adding only propeties is not enough.
I believe you want bgcolor. Something like this:
