Javascript which runs on the client machine can't access the local disk file system due to security restrictions.
If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.
complementing the following comment
For those who use redux:
class AllowanceClass extends Component{
...
render() {
const classes = this.props.classes;
...
}
}
const COMAllowanceClass = (props) =>
{
const classes = useStyles();
return (<AllowanceClass classes={classes} {...props} />);
};
const mapStateToProps = ({ InfoReducer }) => ({
token: InfoReducer.token,
user: InfoReducer.user,
error: InfoReducer.error
});
export default connect(mapStateToProps, { actions })(COMAllowanceClass);
Instead of converting the class to a function, an easy step would be to create a function to include the jsx for the component which uses the 'classes', in your case the <container></container>
and then call this function inside the return of the class render() as a tag. This way you are moving out the hook to a function from the class. It worked perfectly for me. In my case it was a <table>
which i moved to a function- TableStmt outside and called this function inside the render as <TableStmt/>
You are getting this error: "React Hook "useState" is called in function "App" which is neither a React function component or a custom React Hook function"
Solution: You basically need to Capitalize the function.
For example:
const Helper =()=>{}_x000D_
_x000D_
function Helper2(){}
_x000D_
I had a similar issue thanks @ford04 helped me out.
However, another error occurred.
NB. I am using ReactJS hooks
ndex.js:1 Warning: Cannot update during an existing state transition (such as within `render`). Render methods should be a pure function of props and state.
What causes the error?
import {useHistory} from 'react-router-dom'
const History = useHistory()
if (true) {
history.push('/new-route');
}
return (
<>
<render component />
</>
)
This could not work because despite you are redirecting to new page all state and props are being manipulated on the dom or simply rendering to the previous page did not stop.
What solution I found
import {Redirect} from 'react-router-dom'
if (true) {
return <redirect to="/new-route" />
}
return (
<>
<render component />
</>
)
All the answers above are correct, but when I use windows and disable the Prettier ESLint extension rvest.vs-code-prettier-eslint
the issue will be fixed.
If you prefer a useEffect
replacement approach:
const usePreviousEffect = (fn, inputs = []) => {
const previousInputsRef = useRef([...inputs])
useEffect(() => {
fn(previousInputsRef.current)
previousInputsRef.current = [...inputs]
}, inputs)
}
And use it like this:
usePreviousEffect(
([prevReceiveAmount, prevSendAmount]) => {
if (prevReceiveAmount !== receiveAmount) // side effect here
if (prevSendAmount !== sendAmount) // side effect here
},
[receiveAmount, sendAmount]
)
Note that the first time the effect executes, the previous values passed to your fn
will be the same as your initial input values. This would only matter to you if you wanted to do something when a value did not change.
Change your Google Services version from your build.gradle
:
dependencies {
classpath 'com.google.gms:google-services:4.2.0'
}
This is 2 lines of code can listen for back press, from fragments, [TESTED and WORKING]
requireActivity().getOnBackPressedDispatcher().addCallback(getViewLifecycleOwner(), new OnBackPressedCallback(true) {

Google has introduced new AndroidX dependencies. You need to migrate to AndroidX, it's simple.
I replaced all dependencies to AndroidX dependencies
Old design dependency
implementation 'com.android.support:design:28.0.0'
New AndroidX design dependency
implementation 'com.google.android.material:material:1.0.0-rc01'
you can find AndroidX dependencies here https://developer.android.com/jetpack/androidx/migrate
Automatic AndroidX migration option (supported on android studio 3.3+)
Migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.
Since May 23, 2018 update, when you're using a firebase dependency, you must include the firebase-core
dependency, too.
If adding it, you still having the error, try to update the gradle plugin in your gradle-wrapper.properties
to 4.5 version:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip
and resync the project.
I am facing the same issue since 2 days.
ng -v :6.0.8
node -v :8.11.2
npm -v :6.1.0
Make sure you are in the folder where angular.json
is installed. Get into that and type ng serve
. If the issue still arises, then you are having only dependencies installed in node_modules
. Type the following, and it will work:
npm i --only=dev
I m using android studio 3.0 and i upgrade the design pattern dependency from 26.0.1 to 27.1.1 and the error is gone now.
Add Following in gradle
implementation 'com.android.support:design:27.1.1'
It looks like it is a bug open for this issue: Prettier Bug
None of above solution worked for me. The only thing that worked was, adding this line of code in package.json:
"prettier": {
"singleQuote": true
},
modify your app's or module's build.gradle
android {
defaultConfig {
...
minSdkVersion 21 <----- *here
targetSdkVersion 26
multiDexEnabled true <------ *here
}
...
}
According to official documentation
Multidex support for Android 5.0 and higher
Android 5.0 (API level 21) and higher uses a runtime called ART which natively supports loading multiple DEX files from APK files. ART performs pre-compilation at app install time which scans for classesN.dex files and compiles them into a single .oat file for execution by the Android device. Therefore, if your minSdkVersion is 21 or higher, you do not need the multidex support library.
For more information on the Android 5.0 runtime, read ART and Dalvik.
I had similar issue and no errors shown in Compilation. I have tried to clean and rebuild without any success. I managed to find the issue by using Invalidate Caches/Restart from file Menu, after the restart I managed to see the compilation error.
This issue seems to like the following.
How to resolve repository certificate error in Gradle build
Below steps may help:
1. Add certificate to keystore-
Import some certifications into Android Studio JDK cacerts from Android Studio’s cacerts.
Android Studio’s cacerts may be located in
{your-home-directory}/.AndroidStudio3.0/system/tasks/cacerts
I used the following import command.
$ keytool -importkeystore -v -srckeystore {src cacerts} -destkeystore {dest cacerts}
2. Add modified cacert path to gradle.properties-
systemProp.javax.net.ssl.trustStore={your-android-studio-directory}\\jre\\jre\\lib\\security\\cacerts
systemProp.javax.net.ssl.trustStorePassword=changeit
You have not provided providers in your module:
<strike>import { HttpModule } from '@angular/http';</strike>
import { HttpClientModule, HttpClient } from '@angular/common/http';
@NgModule({
imports: [
BrowserModule,
HttpClientModule,
BrowserAnimationsModule,
FormsModule,
AppRoutingModule
],
providers: [ HttpClientModule, ... ]
// ...
})
export class MyModule { /* ... */ }
You will need to add the HttpClientTestingModule
to the TestBed configuration when running ng test
and getting the "No provider for HttpClient" error:
// Http testing module and mocking controller
import { HttpClientTestingModule, HttpTestingController } from '@angular/common/http/testing';
// Other imports
import { TestBed } from '@angular/core/testing';
import { HttpClient, HttpErrorResponse } from '@angular/common/http';
describe('HttpClient testing', () => {
let httpClient: HttpClient;
let httpTestingController: HttpTestingController;
beforeEach(() => {
TestBed.configureTestingModule({
imports: [ HttpClientTestingModule ]
});
// Inject the http service and test controller for each test
httpClient = TestBed.get(HttpClient);
httpTestingController = TestBed.get(HttpTestingController);
});
it('works', () => {
});
});
If you are using Android Studio 3.0 or above make sure your project build.gradle should have content similar to-
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
Note- position really matters add google() before jcenter()
And for below Android Studio 3.0 and starting from support libraries 26.+ your project build.gradle must look like this-
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
check these links below for more details-
The easiest way to avoid suck kind of error is:
-Change library combilesdkversion as same as your app compilesdkversion
-Change library's supportLibrary version as same as your build.gradle(app)
After upgrading some dependency I found solutions. We should use latest play service version. In build.gradle[app] dependency.
compile 'com.android.support:multidex:1.0.2'
compile 'com.google.android.gms:play-services:11.8.0'
compile 'com.google.firebase:firebase-core:11.8.0'
In build.gradle[project], we should use latest Google plug-in.
classpath 'com.google.gms:google-services:3.1.1'
I am also sharing below code for better understanding.
android {
compileSdkVersion 26
buildToolsVersion '26.0.2'
defaultConfig {
applicationId "com.***.user"
minSdkVersion 17
targetSdkVersion 26
versionCode 26
versionName "1.0.20"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
vectorDrawables.useSupportLibrary = true
aaptOptions {
cruncherEnabled = false
}
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
In my case, what I did was a mistake in the url tag in the respective template. So, in my url tag I had something like
{% url 'polls:details' question.id %}
while in the views, I had written something like:
def details(request, question_id): code here
So, the first thing you might wanna check is whether things are spelled as they shoould be. The next thing then you can do is as the people above have suggested.
I also faced the same issue today in my running code. Well, I found a lot of answers here. But the important thing I want to mention is that this error message is quite ambiguous and doesn't explicitly point out the exact error.
Some faced it due to browser extensions, some due to incorrect URL patterns and I faced this due to an error in my formGroup instance used in a pop-up in that screen. So, I would suggest everyone that before making any new changes in your code, please debug your code and verify that you don't have any such errors. You will certainly find the actual reason by debugging.
If nothing else works then check your URL as that is the most common reason for this issue.
If you already use jitpack.io or any repository. You can add google repository like this:
allprojects {
repositories {
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
}
}
If ESLint is running in the terminal but not inside VSCode, it is probably
because the extension is unable to detect both the local and the global
node_modules
folders.
To verify, press Ctrl+Shift+U in VSCode to open
the Output
panel after opening a JavaScript file with a known eslint
issue.
If it shows Failed to load the ESLint library for the document {documentName}.js
-or- if the Problems
tab shows an error or a warning that
refers to eslint
, then VSCode is having a problem trying to detect the path.
If yes, then set it manually by configuring the eslint.nodePath
in the VSCode
settings (settings.json
). Give it the full path (for example, like
"eslint.nodePath": "C:\\Program Files\\nodejs",
) -- using environment variables
is currently not supported.
This option has been documented at the ESLint extension page.
In my case, I was having two different versions of the below implementation in two different modules, So i changed both implementation to versions ie : 6.0.2 and it worked. You may also need to write dependency resolution see the accepted answer.
app module
implementation 'com.karumi:dexter:5.0.0'
commons module
implementation 'com.karumi:dexter:6.0.2'
You can use react-pure-lifecycle to add lifecycle functions to functional components.
Example:
import React, { Component } from 'react';
import lifecycle from 'react-pure-lifecycle';
const methods = {
componentDidMount(props) {
console.log('I mounted! Here are my props: ', props);
}
};
const Channels = props => (
<h1>Hello</h1>
)
export default lifecycle(methods)(Channels);
Appart from setting maven source url to your gradle, I would suggest to add both design and appcompat libraries. Currently the latest version is 26.1.0
maven {
url "https://maven.google.com"
}
...
compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support:design:26.1.0'
I have faced a similar issue working in a multiple modules app environment:
Error: Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'. More than one file was found with OS independent path 'META-INF/AL2.0'
This issue was being reported by several of these modules of mine and none of the above solutions were fixing it. Turns out, I was using version Coroutines 1.3.6 which seemed to be embedding META-INF/AL2.0 which was already embedded by another of the libraries I was using. To fix it, I have added the following code snippet to the build.gradle of the module that was failing:
configurations.all {
resolutionStrategy {
exclude group: "org.jetbrains.kotlinx", module: "kotlinx-coroutines-debug"
}
}
Given that it was happening on multiple modules, I have moved that resolutionStrategy
code to my project level build.gradle.
Everything worked after that.
I also encountered this error when updating to 'com.android.tools.build:gradle:3.0.0'
To fix it, I had to add the google()
repo to both the buildscript and module repositories. The documentation here only mentions adding to to the buildscript.
Project-level build.gradle
buildscript {
repositories {
...
// You need to add the following repository to download the
// new plugin.
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
}
}
App-level build.gradle
repositories {
...
// Documentation doesn't specify this, but it must be added here
google()
}
gradle-wrapper.properties
...
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
I have found one solution to this problem.
Please follow below these steps:
if you're using reactive forms then you can use the following way. consider the following example.
`<p class="mr-3"> Require Shipping:
<input type="radio" class="ml-2" value="true" name="requiresShipping"
id="requiresShipping" formControlName="requiresShipping">
Yes
<input type="radio" class="ml-2" value="false" name="requiresShipping"
id="requiresShipping" formControlName="requiresShipping">
No
</p>`
`
export class ClassName implements OnInit {
public yourForm: FormGroup
constructor(
private fromBuilder: FormBuilder
) {
this.yourForm= this.fromBuilder.group({
requiresShipping: this.fromBuilder.control('true'),
})
}
}
`
now you will get the default selected radio button.
The more secure option would be to add allowedHosts to your Webpack config like this:
module.exports = {
devServer: {
allowedHosts: [
'host.com',
'subdomain.host.com',
'subdomain2.host.com',
'host2.com'
]
}
};
The array contains all allowed host, you can also specify subdomians. check out more here
You can use /* tslint:disable-next-line */
to locally disable tslint. However, as this is a compiler error disabling tslint might not help.
You can always temporarily cast $
to any
:
delete ($ as any).summernote.options.keyMap.pc.TAB
which will allow you to access whatever properties you want.
Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:
if (false) {
// @ts-ignore: Unreachable code error
console.log("hello");
}
Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any
instead as that better expresses intent.
npm install font-awesome --save
add ~/ before path
@import "~/font-awesome/scss/font-awesome.scss";
I recently had this problem.
<Text style={styles.textRegister}> -------- Register With --------</Text>
with this result:
Open gradle-wrapper.properties
Change the version there on distributionUrl
line
In my situation, I did not have an export at the bottom of my webpack.config.js file. Simply adding
export default Config;
solved it.
Switching to the smartphone network & disabling the web security tool installed on my computer solved the problem.
Louis' answer is great, but I thought I would try to sum it up succinctly:
The bang operator tells the compiler to temporarily relax the "not null" constraint that it might otherwise demand. It says to the compiler: "As the developer, I know better than you that this variable cannot be null right now".
overrides:
- files: *-tests.js
rules:
no-param-reassign: 0
You can also set a specific env for a folder, like this :
overrides:
- files: test/*-tests.js
env:
mocha: true
This configuration will fix error message about describe
and it
not defined, only for your test folder:
/myproject/test/init-tests.js
6:1 error 'describe' is not defined no-undef
9:3 error 'it' is not defined no-undef
in my case i was using compile sdk 23
and build tools 25.0.0
just changed compile sdk
to 25 and done..
A somewhat unlikely situation.
I have removed the yarn.lock
file, which referenced an older version of webpack.
So check to see the differences in your yarn.lock
file as a possiblity.
Given
std::vector<Rule>& topPriorityRules;
The correct way to remove the first element of the referenced vector is
topPriorityRules.erase(topPriorityRules.begin());
which is exactly what you suggested.
Looks like i need to do iterator overloading.
There is no need to overload an iterator in order to erase first element of std::vector
.
P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.
You can use assertThrows()
. My example is taken from the docs http://junit.org/junit5/docs/current/user-guide/
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertThrows;
....
@Test
void exceptionTesting() {
Throwable exception = assertThrows(IllegalArgumentException.class, () -> {
throw new IllegalArgumentException("a message");
});
assertEquals("a message", exception.getMessage());
}
Had the same problem.
Fixed by adding the dependency
classpath 'com.google.gms:google-services:3.0.0'
to the root build.gradle
.
https://firebase.google.com/docs/android/setup#manually_add_firebase
I had the same problem in my (YouTube player project)... and the following solved the problem for me:
Add this code into your build.gradle
(module: app) inside defaultConfing
:
defaultConfig {
....
....
multiDexEnabled = true
}
Add this code into your build.gradle
(module: app) inside dependencies
:
dependencies {
compile 'com.android.support:multidex:1.0.1'
.....
.....
}
Open AndroidManifest.xml
and within application
:
<application
android:name="android.support.multidex.MultiDexApplication"
.....
.....
</application>
or if you have your App class, extend it from MultiDexApplication like:
public class MyApp extends MultiDexApplication {
.....
And finally, I think you should have Android Support Repository downloaded, in the Extras in SDK Manager.
In Spring Data you simply define an update query if you have the ID
@Repository
public interface CustomerRepository extends JpaRepository<Customer , Long> {
@Query("update Customer c set c.name = :name WHERE c.id = :customerId")
void setCustomerName(@Param("customerId") Long id, @Param("name") String name);
}
Some solutions claim to use Spring data and do JPA oldschool (even in a manner with lost updates) instead.
You could alter the figsize
by passing a tuple
showing the width, height
parameters you would like to keep.
import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=(10,10)) # Sample figsize in inches
sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5, ax=ax)
EDIT
I remember answering a similar question of yours where you had to set the index as TIMESTAMP
. So, you could then do something like below:
df = df.set_index('TIMESTAMP')
df.resample('30min').mean()
fig, ax = plt.subplots()
ax = sns.heatmap(df.iloc[:, 1:6:], annot=True, linewidths=.5)
ax.set_yticklabels([i.strftime("%Y-%m-%d %H:%M:%S") for i in df.index], rotation=0)
For the head
of the dataframe you posted, the plot would look like:
I know this answer is ridiculous, but consider just disabling this rule until the bugs are worked out or you've upgraded your tooling:
/* eslint-disable react/prop-types */ // TODO: upgrade to latest eslint tooling
Or disable project-wide in your eslintrc:
"rules": {
"react/prop-types": "off"
}
pandas can check for NaT
with pandas.isnull
:
>>> import numpy as np
>>> import pandas as pd
>>> pd.isnull(np.datetime64('NaT'))
True
If you don't want to use pandas you can also define your own function (parts are taken from the pandas source):
nat_as_integer = np.datetime64('NAT').view('i8')
def isnat(your_datetime):
dtype_string = str(your_datetime.dtype)
if 'datetime64' in dtype_string or 'timedelta64' in dtype_string:
return your_datetime.view('i8') == nat_as_integer
return False # it can't be a NaT if it's not a dateime
This correctly identifies NaT values:
>>> isnat(np.datetime64('NAT'))
True
>>> isnat(np.timedelta64('NAT'))
True
And realizes if it's not a datetime or timedelta:
>>> isnat(np.timedelta64('NAT').view('i8'))
False
In the future there might be an isnat
-function in the numpy code, at least they have a (currently open) pull request about it: Link to the PR (NumPy github)
That is the HTML code. Anyone can use this:

});
t.hide();
});
}
Hope it helps.
I got this from YouTube Setting up Python Visual Studio Code... Venv
OK, the video really didn't help me all that much, but... the first comment under (by the person who posted the video) makes a lot of sense and is pure gold.
Basically, open up Visual Studio Code' built-in Terminal. Then source <your path>/activate.sh
, the usual way you choose a venv from the command line. I have a predefined Bash function to find & launch the right script file and that worked just fine.
Quoting that YouTube comment directly (all credit to aneuris ap):
(you really only need steps 5-7)
1. Open your command line/terminal and type `pip virtualenv`.
2. Create a folder in which the virtualenv will be placed in.
3. 'cd' to the script folder in the virtualenv and run activate.bat (CMD).
4. Deactivate to turn of the virtualenv (CMD).
5. Open the project in Visual Studio Code and use its built-in terminal to 'cd' to the script folder in you virtualenv.
6. Type source activates (in Visual Studio Code I use the Git terminal).
7. Deactivate to turn off the virtualenv.
As you may notice, he's talking about activate.bat
. So, if it works for me on a Mac, and it works on Windows too, chances are it's pretty robust and portable.
For me the only thing that works is to add to repositories
maven {
url "https://maven.google.com"
}
It should look like this:
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
Edit: Warning! This answer worked on my XAMPP OsX environment, but when I deployed it to AWS EC2 it did NOT prevent the upload attempt.
I was tempted to delete this answer as it is WRONG But instead I will explain what tripped me up
My file upload field is named 'upload' so I was getting "The upload failed to upload.". This message comes from this line in validation.php:
in resources/lang/en/validaton.php:
'uploaded' => 'The :attribute failed to upload.',
And this is the message displayed when the file is larger than the limit set by PHP.
I want to over-ride this message, which you normally can do by passing a third parameter $messages array to Validator::make() method.
However I can't do that as I am calling the POST from a React Component, which renders the form containing the csrf field and the upload field.
So instead, as a super-dodgy-hack, I chose to get into my view that displays the messages and replace that specific message with my friendly 'file too large' message.
Here is what works if the file to smaller than the PHP file size limit:
In case anyone else is using Laravel FormRequest class, here is what worked for me on Laravel 5.7:
This is how I set a custom error message and maximum file size:
I have an input field <input type="file" name="upload">
. Note the CSRF token is required also in the form (google laravel csrf_field for what this means).
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class Upload extends FormRequest
{
...
...
public function rules() {
return [
'upload' => 'required|file|max:8192',
];
}
public function messages()
{
return [
'upload.required' => "You must use the 'Choose file' button to select which file you wish to upload",
'upload.max' => "Maximum file size to upload is 8MB (8192 KB). If you are uploading a photo, try to reduce its resolution to make it under 8MB"
];
}
}
By default the database in a project in the Firebase Console is only readable/writeable by administrative users (e.g. in Cloud Functions, or processes that use an Admin SDK). Users of the regular client-side SDKs can't access the database, unless you change the server-side security rules.
You can change the rules so that the database is only readable/writeable by authenticated users:
{
"rules": {
".read": "auth != null",
".write": "auth != null"
}
}
See the quickstart for the Firebase Database security rules.
But since you're not signing the user in from your code, the database denies you access to the data. To solve that you will either need to allow unauthenticated access to your database, or sign in the user before accessing the database.
The simplest workaround for the moment (until the tutorial gets updated) is to go into the Database panel in the console for you project, select the Rules tab and replace the contents with these rules:
{
"rules": {
".read": true,
".write": true
}
}
This makes your new database readable and writeable by anyone who knows the database's URL. Be sure to secure your database again before you go into production, otherwise somebody is likely to start abusing it.
For a (slightly) more time-consuming, but more secure, solution, call one of the signIn...
methods of Firebase Authentication to ensure the user is signed in before accessing the database. The simplest way to do this is using anonymous authentication:
firebase.auth().signInAnonymously().catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// ...
});
And then attach your listeners when the sign-in is detected
firebase.auth().onAuthStateChanged(function(user) {
if (user) {
// User is signed in.
var isAnonymous = user.isAnonymous;
var uid = user.uid;
var userRef = app.dataInfo.child(app.users);
var useridRef = userRef.child(app.userid);
useridRef.set({
locations: "",
theme: "",
colorScheme: "",
food: ""
});
} else {
// User is signed out.
// ...
}
// ...
});
In your app's build.gradle
add the following:
android {
configurations.all {
resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
}
}
Enforces Gradle to only compile the version number you state for all dependencies, no matter which version number the dependencies have stated.
delete C:\Users\username\.gradle\caches
folder.
jQuery.is()
function does not have a signature for .is('selector', function)
.
I guess you want to do something like this:
if($("#checkbox1").is(':checked')){
$("#checkbox1").attr('value', 'true');
}
You can configure this in mysql configuration file
open /etc/my.cnf
file
In this file all the lines which is configuring the password policy make those commented like
#validate-password=FORCE_PLUS_PERMANENT
#validate_password_length=10
#validate_password_mixed_case_count=1
#validate_password_number_count=1
#validate_password_policy=MEDIUM
Uncomment and change the value of the properties you want to change.
You don't need floats. In fact, they're useless because floats are ignored in flexbox.
You also don't need CSS positioning.
There are several flex methods available. auto
margins have been mentioned in another answer.
Here are two other options:
justify-content: space-between
and the order
property.justify-content: space-between
and reverse the order of the divs..parent {_x000D_
display: flex;_x000D_
justify-content: space-between;_x000D_
}_x000D_
_x000D_
.parent:first-of-type > div:last-child { order: -1; }_x000D_
_x000D_
p { background-color: #ddd;}

I have same problem, because i don't have keystore path then i see Waffles.inc solutions and had a new problem In my Android Studio 3.1 for mac had a windows dialog problem when trying create new keystore path, it's like this
if u have the same problem, don't worried about the black windows it's just typing your new keystore and then save.
Originally, the solution was to provide the following config as object destructuring used to be an experimental feature and not supported by default:
{
"parserOptions": {
"ecmaFeatures": {
"experimentalObjectRestSpread": true
}
}
}
Since version 5, this option has been deprecated.
Now it is enough just to declare a version of ES, which is new enough:
{
"parserOptions": {
"ecmaVersion": 2018
}
}
A great substitute for np.isnan() and pd.isnull() is
for i in range(0,a.shape[0]):
if(a[i]!=a[i]):
//do something here
//a[i] is nan
since only nan is not equal to itself.
It worked to me only using a specific service.
For example instead of use:
compile 'com.google.android.gms:play-services:10.0.1'
I used:
com.google.android.gms:play-services-places:10.0.1
Bootstrap 4 has all you need : USE THE .d-flex
and .flex-fill
class. Don't use the card-decks
as they are not responsive.
I used col-sm
, you can use the .col
class you want, or use col-lg-x
the x means number of width column e.g 4 or 3 for best view if the post have many then 3 or 4 per column

The minium sdk version should be same as of the modules/lib you are using For example: Your module min sdk version is 26 and your app min sdk version is 21 It should be same.
If you have another instance of Android Studio running, then kindly close it and then build the app. This worked in my case
I also came across the same error. Here is the fix: If you are using Cmake-GUI:
If you missed the 3rd step:
*** No rule to make target `install'. Stop.
error will occur.
This just happened to me. It turned out I was requesting ALL permissions, when I needed to filter to just DANGEROUS permissions, and it suddenly started working.
fun requestPermissions() {
val missingDangerPermissions = PERMISSIONS
.filter { ContextCompat.checkSelfPermission(this, it) != PackageManager.PERMISSION_GRANTED }
.filter { this.getPackageManager().getPermissionInfo(it, PackageManager.GET_META_DATA).protectionLevel == PermissionInfo.PROTECTION_DANGEROUS } // THIS FILTER HERE!
if (missingDangerPermissions.isNotEmpty()) {
Log.i(TAG, "Requesting dangerous permission to $missingDangerPermissions.")
ActivityCompat.requestPermissions(this,
missingDangerPermissions.toTypedArray(),
REQUEST_CODE_REQUIRED_PERMISSIONS);
return
} else {
Log.i(TAG, "We had all the permissions we needed (yay!)")
}
}
Both the regex and included files are good methods, and I frequently use those. But another alternative is to use a "named location", which is a useful approach in many situations — especially more complicated ones. The official "If is Evil" page shows essentially the following as a good way to do things:
error_page 418 = @common_location;
location /first/location/ {
return 418;
}
location /second/location/ {
return 418;
}
location @common_location {
# The common configuration...
}
There are advantages and disadvantages to these various approaches. One big advantage to a regex is that you can capture parts of the match and use them to modify the response. Of course, you can usually achieve similar results with the other approaches by either setting a variable in the original block or using map
. The downside of the regex approach is that it can get unwieldy if you want to match a variety of locations, plus the low precedence of a regex might just not fit with how you want to match locations — not to mention that there are apparently performance impacts from regexes in some cases.
The main advantage of including files (as far as I can tell) is that it is a little more flexible about exactly what you can include — it doesn't have to be a full location block, for example. But it's also just subjectively a bit clunkier than named locations.
Also note that there is a related solution that you may be able to use in similar situations: nested locations. The idea is that you would start with a very general location, apply some configuration common to several of the possible matches, and then have separate nested locations for the different types of paths that you want to match. For example, it might be useful to do something like this:
location /specialpages/ {
# some config
location /specialpages/static/ {
try_files $uri $uri/ =404;
}
location /specialpages/dynamic/ {
proxy_pass http://127.0.0.1;
}
}
Find your own local android-SDK, if you download the relevant SDK of ndk, there will be a folder called "ndk-bundle"
There is a folder called "toolchains" inside.
We noticed that there are no mips64el related files inside.
The solution is as follows:
Click here to download the NDK package separately through the browser. After unzipping, open the "toolchains" folder, compare it with the android-sdk->ndk-bundle->toolchains folder, find the missing folder, copy the past three. Recompile, the problem is solved.
Sometimes the reason of these errors are not the DataBinding
itself, but some other part of our code. In my case I had an error in Room
database so the compiler couldn't generate the binding classes and it gives me these errors.
According to Google:
Previous versions of the data binding compiler generated the binding classes in the same step that compiles your managed code. If your managed code fails to compile, you might get multiple errors reporting that the binding classes aren't found. The new data binding compiler prevents these errors by generating the binding classes before the managed compiler builds your app.
So to enable new data binding compiler, add the following option to your gradle.properties file:
android.databinding.enableV2=true
You can also enable the new compiler in your gradle command by adding the following parameter:
-Pandroid.databinding.enableV2=true
Note that the new compiler in Android Studio version 3.2 is enabled by default.
You can just put this for example at the top of the file:
/* eslint-disable no-console */
Just Android studio run 'Run as administrator' it will work
Or verify your package name on google-services.json file
In my case it is Asp.Net Core 3.1 API. I changed the HTTP GET method from public ActionResult GetValidationRulesForField( GetValidationRulesForFieldDto getValidationRulesForFieldDto)
to public ActionResult GetValidationRulesForField([FromQuery] GetValidationRulesForFieldDto getValidationRulesForFieldDto)
and its working.
I was encountering the same issue. In my App build.gradle I had
apply plugin: 'com.android.application'
apply plugin: 'dexguard'
apply plugin: 'io.fabric'
I just switched Dexguard and Fabric, then it worked!
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'dexguard'
If you're still having trouble even after configuring your package.json according to the documentation (if you've opted to use package.json to track rather than separate config files):
"rules": {
"no-console": "off"
},
And it still isn't working for you, don't forget you need to go back to the command line and do npm install again. :)
If you want to set specific learning rates for intervals of epochs like 0 < a < b < c < ...
. Then you can define your learning rate as a conditional tensor, conditional on the global step, and feed this as normal to the optimiser.
You could achieve this with a bunch of nested tf.cond
statements, but its easier to build the tensor recursively:
def make_learning_rate_tensor(reduction_steps, learning_rates, global_step):
assert len(reduction_steps) + 1 == len(learning_rates)
if len(reduction_steps) == 1:
return tf.cond(
global_step < reduction_steps[0],
lambda: learning_rates[0],
lambda: learning_rates[1]
)
else:
return tf.cond(
global_step < reduction_steps[0],
lambda: learning_rates[0],
lambda: make_learning_rate_tensor(
reduction_steps[1:],
learning_rates[1:],
global_step,)
)
Then to use it you need to know how many training steps there are in a single epoch, so that we can use the global step to switch at the right time, and finally define the epochs and learning rates you want. So if I want the learning rates [0.1, 0.01, 0.001, 0.0001]
during the epoch intervals of [0, 19], [20, 59], [60, 99], [100, \infty]
respectively, I would do:
global_step = tf.train.get_or_create_global_step()
learning_rates = [0.1, 0.01, 0.001, 0.0001]
steps_per_epoch = 225
epochs_to_switch_at = [20, 60, 100]
epochs_to_switch_at = [x*steps_per_epoch for x in epochs_to_switch_at ]
learning_rate = make_learning_rate_tensor(epochs_to_switch_at , learning_rates, global_step)
Go into Build ->
Clean Project ->
Run project : done
working on android 5.1 for me
Important note: You should only apply plugin at bottom of build.gradle (App level)
apply plugin: 'com.google.gms.google-services'
I mistakenly apply this plugin at top of the build.gradle. So I get error.
One more tips : You no need to remove even you use the 3.1.0 or above. Because google not officially announced
classpath 'com.google.gms:google-services:3.1.0'
Had the same issue with another number, this worked for me:
Click the error message at top "Gradle project sync failed" where the text says ´Open message view´
In the "Message Gradle Sync" window on the bottom left corner, click the provided solution "Install missing ... "
Repeat 1 and 2 if necessary
23:08 Gradle sync failed: Failed to find target with hash string 'android-26' in: C:\Users\vik\AppData\Local\Android\Sdk
If all the above didn't work for you try removing cache from .gradle
global folder
rm -rf ~/.gradle/caches
react-native run-android
rm -rf ~/.gradle
react-native run-android
You can force the annotation library in your test using:
androidTestCompile 'com.android.support:support-annotations:23.1.0'
Something like this:
// Force usage of support annotations in the test app, since it is internally used by the runner module.
androidTestCompile 'com.android.support:support-annotations:23.1.0'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'
Another solution is to use this in the top level file:
configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
}
There may be different reason for reported issue, few days back also face this issue 'duplicate jar', after upgrading studio. From all stackoverflow I tried all the suggestion but nothing worked for me.
But this is for sure some duplicate jar is there, For me it was present in one library libs folder as well as project libs folder. So I removed from project libs folder as it was not required here. So be careful while updating the studio, and try to understand all the gradle error.
Please remove all jar
files of Http from 'libs' folder and add below dependencies in gradle file:
compile 'org.apache.httpcomponents:httpclient:4.5'
compile 'org.apache.httpcomponents:httpcore:4.4.3'
or
useLibrary 'org.apache.http.legacy'
if you faced this problem you can completely resolve it by changing :
build.gradle(project: ...)
replace this
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenCentral()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
As seen in the revision column of the Android SDK Manager, the latest published version of the Support Library is 22.2.1. You'll have to wait until 23.0.0 is published.
Edit: API 23 is already published. So u can use 23.0.0
For your information, it really depends on your hosting provider.
In my case (Infomaniak), nothing above actually worked and I got infinite redirect loop.
The right way to do this is actually explained in their support site:
RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://your-domain.com/$1 [R=301,L]
So, always check with your hosting provider. Hopefully they have an article explaining how to do this. Otherwise, just ask the support.
I solved the problem REF
Run

Assuming you're using Spring Boot, another option is to put the following in your application.properties
:
logging.level.org.springframework.security=DEBUG
This is the same for most other Spring modules as well.
If you're not using Spring Boot, try setting the property in your logging configuration, e.g. logback.
Here is the application.yml version as well:
logging:
level:
org:
springframework:
security: DEBUG
This is because your PNG file is not supported or else you renamed your file directly.
Do the following steps.
Problem solved :)
I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:
Make sure ESLint is not run with the --no-inline-config
flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):
/* eslint-env browser */
This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.
There are plenty of environments, and you can declare more than one at the same time, for example, in-line:
/* eslint-env browser, node */
If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.
From their docs:
An environment defines global variables that are predefined. The available environments are:
browser
- browser global variables.node
- Node.js global variables and Node.js scoping.commonjs
- CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).shared-node-browser
- Globals common to both Node and Browser.[...]
Besides environments, you can make it ignore anything you want. If it warns you about using console.log()
but you don't want to be warned about it, just inline:
/* eslint-disable no-console */
You can see the list of all rules, including recommended rules to have for best coding practices.

To build your application without aidl is missing
error with compileSdkVersion 23
and buildToolsVersion "23.0.1"
you should specify latest versions for Android Gradle plugin (and Google Play Services Gradle plugin if you are using it) in main build.gradle
file:
buildscript {
repositories {
...
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.1'
classpath 'com.google.gms:google-services:1.3.1'
}
}
For me the problem was, i had put a unnecessary complie library code in build.gradle
dependencies {
compile 'com.google.android.gms:play-services:7.5.0'
}
which was causing over 65k methods, so removed it,gradle sync, cleaned project, and then ran again and then this error stopped. I needed just maps and gcm so i put these lines and synced project
compile 'com.google.android.gms:play-services-gcm:7.5.0'
compile 'com.google.android.gms:play-services-location:7.5.0'
Hi people i again encountered this problem and this time it was because of changing build tools version and it really required me to enable multidex..so i added these my app's build.gradle file..
defaultConfig {
applicationId "com.am.android"
minSdkVersion 13
targetSdkVersion 23
// Enabling multidex support.
multiDexEnabled true
}
dexOptions {
incremental true
javaMaxHeapSize "2048M"
jumboMode = true
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:multidex:1.0.1'
}
And create a class that extends Application class and include this method inside the class..
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
also include in OnCreate method too
@Override
public void onCreate() {
MultiDex.install(this);
super.onCreate();
}
I too was facing this issue just because i had renamed my project folder while project was opened in Android Sudio.So,Android Studio created another folder in that directory of my window.
I found in my build.gradle(Module:app), all the support libraries were updated and was throwing error on compile time of project.
All you require to do is,simply change updated support libraries to your current build tool version like this and rebuild the project.
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:design:22.2.1'
compile 'com.android.support:cardview-v7:22.2.1'
my current build tool version is 22.2.1
This is android's way of telling you to upgrade gradle to the most recent version. You can do two things-
I've had the same issue just now, and it turned out to be caused by a faulty attrs.xml
file in one of my modules. The file initially had two stylable attributes for one of my custom views, but I had deleted one when it turned out I no longer needed it. This was apparently, however, not registered correctly with the IDE and so the build failed when it couldn't find the attribute.
The solution for me was to re-add the attribute, run a clean project
after which the build succeeded and I could succesfully remove the attribute again without any further problems.
Hope this helps someone.
After using pngcheck and resave all my image files to *.png, the problem still.
Finally, I found the issue is about *.9.png files. Open and check all your 9-Patch files, make sure that all files have black lines as below, if don't have, just click the white place and add it, then save it.
Try to put this line of code in your main projects gradle script:
configurations { all*.exclude group: 'com.android.support', module: 'support-v4' }
I have two libraries linked to my project and they where using 'com.android.support:support-v4:22.0.0'.
Hope it helps someone.
This was working for me so Try This: $ad->getcodes()->distinct('pid')->count()
I faced this exception for a long time and was not able to pinpoint the problem. The exception says line 1 column 9. The mistake I did is to get the first line of the file which flume is processing.
Apache flume process the content of the file in patches. So, when flume throws this exception and says line 1, it means the first line in the current patch.
If your flume agent is configured to use batch size = 100, and (for example) the file contains 400 lines, this means the exception is thrown in one of the following lines 1, 101, 201,301.
How to discover the line which causes the problem?
You have three ways to do that.
1- pull the source code and run the agent in debug mode. If you are an average developer like me and do not know how to make this, check the other two options.
2- Try to split the file based on the batch size and run the flume agent again. If you split the file into 4 files, and the invalid json exists between lines 301 and 400, the flume agent will process the first 3 files and stop at the fourth file. Take the fourth file and again split it into more smaller files. continue the process until you reach a file with only one line and flume fails while processing it.
3- Reduce the batch size of the flume agent to only one and compare the number of processed events in the output of the sink you are using. For example, in my case I am using Solr sink. The file contains 400 lines. The flume agent is configured with batch size=100. When I run the flume agent, it fails at some point and throw that exception. At this point check how many documents are ingested in Solr. If the invalid json exists at line 346, the number of documents indexed into Solr will be 345, so the next line is the line which causes the problem.
In my case I followed the third option and fortunately I pinpoint the line which causes the problem.
This is a long answer but it actually does not solve the exception. How I overcome this exception?
I have no idea why Jackson library complain while parsing a json string contains escaped characters \n \r \t
. I think (but I am not sure) the Jackson parser is by default escaping these characters which cases the json string to be split into two lines (in case of \n
) and then it deals each line as a separate json string.
In my case we used a customized interceptor to remove these characters before being processed by the flume agent. This is the way we solved this problem.
When you call a Linq statement like this:
// x = new List<string>();
var count = x.Count(s => s.StartsWith("x"));
You are actually using an extension method in the System.Linq namespace, so what the compiler translates this into is:
var count = Enumerable.Count(x, s => s.StartsWith("x"));
So the error you are getting above is because the first parameter, source
(which would be x
in the sample above) is null.
I had the same problem, the first thing that came to mind was repositories. So I checked the build.gradle
file for the whole project and added the following code, then synchronized the gradle with project and problem was solved!
allprojects {
repositories {
jcenter()
}
}
This work for me in Laravel 7.x in 3 simple steps using a middleware:
1) Generate the middleware with command php artisan make:middleware ForceSSL
Middleware
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\App;
class ForceSSL
{
public function handle($request, Closure $next)
{
if (!$request->secure() && App::environment() === 'production') {
return redirect()->secure($request->getRequestUri());
}
return $next($request);
}
}
2) Register the middleware in routeMiddleware
inside Kernel file
Kernel
protected $routeMiddleware = [
//...
'ssl' => \App\Http\Middleware\ForceSSL::class,
];
3) Use it in your routes
Routes
Route::middleware('ssl')->group(function() {
// All your routes here
});

========================
.HTACCESS Method
If you prefer to use an .htaccess
file, you can use the following code:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://yourdomain.com/$1 [R,L]
</IfModule>
Regards!
https://github.com/dipeshsukhia/laravel-remove-public-url
you can use this package
composer require dipeshsukhia/laravel-remove-public-url --dev
php artisan vendor:publish --tag=LaravelRemovePublicUrl
For those who are using laravel 5 or above must use public modifier other wise it will throw an exception
Access level to App\yourModelName::$timestamps must be
public (as in class Illuminate\Database\Eloquent\Model)
public $timestamps = false;
With the kind help from Tim Williams, I finally figured out the last détails that were missing. Here's the final code below.
Private Sub Open_multiple_sub_pages_from_main_page()

IE.Visible = True
' Send the form data To URL As POST binary request
IE.navigate "http://webpage.com/"
' Wait while IE loading...
While IE.Busy
DoEvents
Wend
Set objCollection = IE.Document.getElementsByTagName("input")
i = 0
While i < objCollection.Length
If objCollection(i).Name = "txtUserName" Then
' Set text for search
objCollection(i).Value = "1234"
End If
If objCollection(i).Name = "txtPwd" Then
' Set text for search
objCollection(i).Value = "password"
End If
If objCollection(i).Type = "submit" And objCollection(i).Name = "btnSubmit" Then ' submit button if found and set
Set objElement = objCollection(i)
End If
i = i + 1
Wend
objElement.Click ' click button to load page
' Wait while IE re-loading...
While IE.Busy

IE.Visible = True
Set Doc = IE.Document
Dim links, link
Dim j As Integer 'variable to count items
j = 0
Set links = IE.Document.getElementById("dgTime").getElementsByTagName("a")
n = links.Length
While j <= n 'loop to go thru all "a" item so it loads next page
links(j).Click

End Sub
To disable next line:
// eslint-disable-next-line no-use-before-define
var thing = new Thing();
Or use the single line syntax:
var thing = new Thing(); // eslint-disable-line no-use-before-define
See the eslint docs
I don't know if maybe it's a difference in Excel version but this question is 6 years old and the accepted answer didn't help me so this is what I figured out:
Under Conditional Formatting > Manage Rules:
$A2<$B2
$B$2:$B$100
(assuming you have 100 rows)This worked for me in Excel 2016.
Also, there was just a typo in your original post.
'min:2|max5'
should have been 'min:2|max:5'
.
Notice the ":" for the "max" rule.
You can download the gradle you want from Gradle Service by reading the gradle-wrapper.properties.Download it ,unpack it where you like and then change your grandle configuration use local not the recommended.
I would use the path npm module and then do something like this:
var path = require('path');
app.use('/scripts', express.static(path.join(__dirname, 'node_modules/bootstrap/dist')));
IMPORTANT: we use path.join to make paths joining using system agnostic way, i.e. on windows and unix we have different path separators (/ and )
It does work indeed. Issue was with my less compiler. It was compiled in to:
.container {
min-height: calc(-51vh);
}
Fixed with the following code in less file:
.container {
min-height: calc(~"100vh - 150px");
}
Thanks to this link: Less Aggressive Compilation with CSS3 calc
Using 'minifyEnabled'
instead of 'runProguard'
works properly.
Previous code:
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
Current code:
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
Hope this helps.
Move all that in kernel.php if just the above method didn't work for you remember you have to move all those lines in kernel.php in addition to the above solution
let me first display the way it is there in the file already..
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
];
/**
* The application's route middleware groups.
*
* @var array
*/
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
],
'api' => [
'throttle:60,1',
],
];
now what you have to do is
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
];
/**
* The application's route middleware groups.
*
* @var array
*/
protected $middlewareGroups = [
'web' => [
],
'api' => [
'throttle:60,1',
],
];
i.e.;
I removed these lines as below :
before :
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar1"
android:layout_width="match_parent"
android:layout_height="@attr/actionBarSize"
android:minHeight="@attr/actionBarSize"
android:layout_alignParentTop="true" >
after :
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar1"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentTop="true" >
Instead of "@attr/actionBarSize" put specific dimens it works for me.
Add this code in your validate method:
errorLabelContainer: '#errors'
and in your html, put simply this where you want to catch the error:
<div id="errors"></div>
All the errors will be held in the div, independently of your input box.
It worked very fine for me.
Instead of the *
selector you can use the :not(selector)
with the >
selector and set something that definitely wont be a child.
Edit: I thought it would be faster but it turns out I was wrong. Disregard.
Example:
.container > :not(marquee){
color:red;
}
<div class="container">
<p></p>
<span></span>
<div>
If you are not tweaking the curl command too much you can also go and call the curl command directly
import shlex
cmd = '''curl -X POST -d '{"nw_src": "10.0.0.1/32", "nw_dst": "10.0.0.2/32", "nw_proto": "ICMP", "actions": "ALLOW", "priority": "10"}' http://localhost:8080/firewall/rules/0000000000000001'''
args = shlex.split(cmd)
process = subprocess.Popen(args, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()
Another example using PowerShell for set permissions (File / Directory) :
Get-Acl "C:\file.txt" | fl *
$acl = Get-Acl "C:\file.txt"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule("everyone","FullControl","Allow")
$acl.SetAccessRule($accessRule)
$acl | Set-Acl "C:\file.txt"
Hope this helps
In my case, the folder which served the files was a symbolic link to another folder, made with
ln -sf /origin /var/www/destination
Even though the permissions (user and group) where correct on the destination folder (the symbolic link), I still had the error because Nginx needed to have permissions to the origin folder whole's hierarchy as well.
For me it helped to add ?$query_string
at the end of /index.php, like below:
location / {
try_files $uri $uri/ /index.php?$query_string;
}
If you want to allow all the fonts from a folder for a specific domain then you can use this:
<location path="assets/font">
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="http://localhost:3000" />
</customHeaders>
</httpProtocol>
</system.webServer>
</location>
where assets/font is the location where all fonts are and http://localhost:3000 is the location which you want to allow.
If in your site you have ajax calls loading some data, and this is the reason the page is loading slow, the best solution I found is with
$(document).ajaxStop(function(){
alert("All AJAX requests completed");
});
https://jsfiddle.net/44t5a8zm/ - here you can add some ajax calls and test it.
Even though the port is open, MongoDB is currently only listening on the local address 127.0.0.1. To allow remote connections, add your server’s publicly-routable IP address to the mongod.conf file.
Open the MongoDB configuration file in your editor:
sudo nano /etc/mongodb.conf
Add your server’s IP address to the bindIP value:
...
logappend=true
bind_ip = 127.0.0.1,your_server_ip
#port = 27017
...
Note that now everybody who has the username and password can login to your DB and you want to avoid this by restrict the connection only for specific IP's. This can be done using Firewall (read about UFW service at Google). But in short this should be something like this:
sudo ufw allow from YOUR_IP to any port 27017
I still got the error
Could not find com.android.tools.build:gradle:3.0.0.
Problem: jcenter() did not have the required libs
Solution: add google() as repo
buildscript {

google()
jcenter()

dependencies {
classpath "com.android.tools.build:gradle:3.0.0"
}
}
Just installed Android Studio v 0.8.1 beta and ran into the same problem targeting SDK 19.
Copied 19 from the adt-bundle to android-studio, changed build.gradle to:
compileSdkVersion 19 targetSdkVersion 19
then project -> app -> open module settings (aka project structure): change compile sdk version to 19.
Now works fine.
If anyone is looking for a simple solution in Laravel 5.3:
timestamps()
be saved as is i.e. '2016-11-14 12:19:49'In your views, format the field as below (or as required):
date('F d, Y', strtotime($list->created_at))
It worked for me very well for me.
If you use the moment js library it can easily be done like this -
jQuery.validator.addMethod("validDate", function(value, element) {
return this.optional(element) || moment(value,"DD/MM/YYYY").isValid();
}, "Please enter a valid date in the format DD/MM/YYYY");
Technically, it is possible to change the color of anything with CSS. As mentioned, you can't change the background-color or color but you can use CSS filters. For example:
input[type="checkbox"] { /* change "blue" browser chrome to yellow */
filter: invert(100%) hue-rotate(18deg) brightness(1.7);
}
If you are really looking for design control over checkboxes though, your best bet is to do the "hidden" checkbox and style an adjacent element such as a div.
I am posting an answer here, since I had the same error message for a different reason.
This error message can happen, for example, if you are using apache httpd to proxy requests from a source on protocol A to target on protocol B.
Here is the example of my situation:
AH01144: No protocol handler was valid for the URL /sockjs-node/info (scheme 'ws').
In the case above, what was happening was simply the following. I had enabled mod proxy to proxy websocket requests to nodejs based on path /sockjs-node.
The problem is that node does not use the path /sockjs-node for websocket requests exclusively. It also uses this path for hosting REST entrypoints that deliver information about websockets.
In this manner, when the application would try to open http://localhost:7001/sockjs-node/info, apache httpd would be trying to route the rest call from HTTP protocol to to a Webscoket endpoint call. Node did not accept this.
This lead to the exception above.
So be mindful that even if you enable the right modules, if you try to do the wrong forwarding, this will end with apache httpd informing you that the protocol you tried to use on the target server is not valid.
I tried this on Laravel 4.2
Rename the server.php
in the your Laravel root folder to index.php
and copy the .htaccess
file from /public
directory to your Laravel root folder.
I hope it works
My answer is based on getting a 403 error although I had all of the Apache settings mentioned in the other answers correct.
It was a fresh Centos 7 server and it turned out that the issue was not the Apache settings but the fact that the PhpMyAdmin did not serve at all. The solution was to install php and add the php directive to apache.conf:
Don't forget to restart Apache server to take effect - systemctl restart httpd.service
I hope this helps. I first thought my issue was Apache directives, so I post my solution here.
There is an elegant way to do this. If you are using Resource Controllers, your link to edit your record will look like this:
/users/{user}/edit OR /users/1/edit
And in your UserRequest, the rule should be like this :
public function rules()
{
return [
'name' => [
'required',
'unique:users,name,' . $this->user
],
];
}
Or if your link to edit your record look like this:
/users/edit/1
You can try this also:
public function rules()
{
return [
'name' => [
'required',
'unique:users,name,' . $this->id
],
];
}
I would be using laravel whereDoesntHave to achieve this.
Customer::whereDoesntHave('orders')->get();
You get the error because if
can only evaluate a logical
vector of length 1.
Maybe you miss the difference between &
(|
) and &&
(||
). The shorter version works element-wise and the longer version uses only the first element of each vector, e.g.:
c(TRUE, TRUE) & c(TRUE, FALSE)
# [1] TRUE FALSE
# c(TRUE, TRUE) && c(TRUE, FALSE)
[1] TRUE
You don't need the if
statement at all:
mut1 <- trip$Ref.y=='G' & trip$Variant.y=='T'|trip$Ref.y=='C' & trip$Variant.y=='A'
trip[mut1, "mutType"] <- "G:C to T:A"
To allow from all:
#Require ip 127.0.0.1
#Require ip ::1
Require all granted
You've mixed tabs and spaces. __init__
is actually defined nested inside another method, so your class doesn't have its own __init__
method, and it inherits object.__init__
instead. Open your code in Notepad instead of whatever editor you're using, and you'll see your code as Python's tab-handling rules see it.
This is why you should never mix tabs and spaces. Stick to one or the other. Spaces are recommended.
I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.
The solution was built all using "compiler compliance level: 1.7" and "Generated .class files compatibility: 1.6", "Source compatibility: 1.6".
I setup this option in Eclipse: Preferences\Java\Compiler.
Thanks everybody.
Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when
and verify
.
Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T>
and expose a method matches(T)
that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.
/* Mockito */ verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));
Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T
where Hamcrest matcher methods return Matcher objects (of type Matcher<T>
).
Mockito matchers are invoked through static methods such as eq
, any
, gt
, and startsWith
on org.mockito.Matchers
and org.mockito.AdditionalMatchers
. There are also adapters, which have changed across Mockito versions:
Matchers
featured some calls (such as intThat
or argThat
) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T>
extended org.hamcrest.Matcher<T>
, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.Matchers
calls phrased as intThat
or argThat
wrap ArgumentMatcher<T>
objects that no longer implement org.hamcrest.Matcher<T>
but are used in similar ways. Hamcrest adapters such as argThat
and intThat
are still available, but have moved to MockitoHamcrest
instead.Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:
/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));
In the above statement: foo.setPowerLevel
is a method that accepts an int
. is(greaterThan(9000))
returns a Matcher<Integer>
, which wouldn't work as a setPowerLevel
argument. The Mockito matcher intThat
wraps that Hamcrest-style Matcher and returns an int
so it can appear as an argument; Mockito matchers like gt(9000)
would wrap that entire expression into a single call, as in the first line of example code.
when(foo.quux(3, 5)).thenReturn(true);
When not using argument matchers, Mockito records your argument values and compares them with their equals
methods.
when(foo.quux(eq(3), eq(5))).thenReturn(true); // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different
When you call a matcher like any
or gt
(greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture()
it stores a matcher that saves its argument instead for later inspection.
Matchers return dummy values such as zero, empty collections, or null
. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt()
or any(Integer.class)
or an empty List<String>
for anyListOf(String.class)
. Because of type erasure, though, Mockito lacks type information to return any value but null
for any()
or argThat(...)
, which can cause a NullPointerException if trying to "auto-unbox" a null
primitive value.
Matchers like eq
and gt
take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.
Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt())
or thenReturn(any(Foo.class))
in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.
Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.
Most matcher calls only add to this stack, with an exception for matchers like and
, or
, and not
. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:
when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6] [5] [1] [4] [2] [3]
This will:
anyInt()
to the stack.gt(10)
to the stack.lt(20)
to the stack.gt(10)
and lt(20)
and add and(gt(10), lt(20))
.foo.quux(0, 0)
, which (unless otherwise stubbed) returns the default value false
. Internally Mockito marks quux(int, int)
as the most recent call.when(false)
, which discards its argument and prepares to stub method quux(int, int)
identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any()
matcher for its first argument and and(gt(10), lt(20))
for its second argument and clears the stack.This demonstrates a few rules:
Mockito can't tell the difference between quux(anyInt(), 0)
and quux(0, anyInt())
. They both look like a call to quux(0, 0)
with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.
Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.
int between10And20 = and(gt(10), lt(20));
/* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
// Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
/* OK */ when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
// The helper method calls the matcher methods in the right order.
The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when
or verify
, but Mockito can't check that automatically.
You can check manually with Mockito.validateMockitoUsage()
.
In a call to when
, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values).
doReturn
and doAnswer
(etc) do not invoke the actual method and are often a useful alternative.
If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq
matcher), Mockito would check the stack length against that call instead, and likely fail.
If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final
method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.
InvalidUseOfMatchersException:
Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when
or verify
call. Matchers should never be used as stubbed return values or fields/variables.
Check that you're not calling a mock as a part of providing a matcher argument.
Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.
NullPointerException with primitive arguments: (Integer) any()
returns null while any(Integer.class)
returns 0; this can cause a NullPointerException
if you're expecting an int
instead of an Integer. In any case, prefer anyInt()
, which will return zero and also skip the auto-boxing step.
NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz)
will actually call foo.bar(null)
, which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any())
skips the stubbed behavior.
Use MockitoJUnitRunner, or explicitly call validateMockitoUsage
in your tearDown
or @After
method (which the runner would do for you automatically). This will help determine whether you've misused matchers.
For debugging purposes, add calls to validateMockitoUsage
in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.

You need a ResourceLink in your META-INF/context.xml
file to make the global resource available to the web application.
<ResourceLink name="jdbc/mydb"
global="jdbc/mydb"
type="javax.sql.DataSource" />
How about just > Format only cells that contain - in the drop down box select Blanks
If you have another column which is being used as foreign key or index then you have to specify that as well in the rule like this.
'phone' => [
"required",
"phone",
Rule::unique('shops')->ignore($shopId, 'id')->where(function ($query) {
$query->where('user_id', Auth::id());
}),
],
Try this:
myfile %>% mutate(V5 = (V1 == 1 & V2 != 4) + 2 * (V2 == 4 & V3 != 1))
giving:
V1 V2 V3 V4 V5
1 1 2 3 5 1
2 2 4 4 1 2
3 1 4 1 1 0
4 4 5 1 3 0
5 5 5 5 4 0
or this:
myfile %>% mutate(V5 = ifelse(V1 == 1 & V2 != 4, 1, ifelse(V2 == 4 & V3 != 1, 2, 0)))
giving:
V1 V2 V3 V4 V5
1 1 2 3 5 1
2 2 4 4 1 2
3 1 4 1 1 0
4 4 5 1 3 0
5 5 5 5 4 0
Suggest you get a better name for your data frame. myfile makes it seem as if it holds a file name.
Above used this input:
myfile <-
structure(list(V1 = c(1L, 2L, 1L, 4L, 5L), V2 = c(2L, 4L, 4L,
5L, 5L), V3 = c(3L, 4L, 1L, 1L, 5L), V4 = c(5L, 1L, 1L, 3L, 4L
)), .Names = c("V1", "V2", "V3", "V4"), class = "data.frame", row.names = c("1",
"2", "3", "4", "5"))
Update 1 Since originally posted dplyr has changed %.%
to %>%
so have modified answer accordingly.
Update 2 dplyr now has case_when
which provides another solution:
myfile %>%
mutate(V5 = case_when(V1 == 1 & V2 != 4 ~ 1,
V2 == 4 & V3 != 1 ~ 2,
TRUE ~ 0))
I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.
I have to assume you are using windows because you have mentioned notepad++.
Use notepad++. Right click on the file and choose "edit with notepad++"
Use notepad Change the filename extension to .txt and double click the file.
Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"
If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.
To understand circular dependencies, you need to remember that Python is essentially a scripting language. Execution of statements outside methods occurs at compile time. Import statements are executed just like method calls, and to understand them you should think about them like method calls.
When you do an import, what happens depends on whether the file you are importing already exists in the module table. If it does, Python uses whatever is currently in the symbol table. If not, Python begins reading the module file, compiling/executing/importing whatever it finds there. Symbols referenced at compile time are found or not, depending on whether they have been seen, or are yet to be seen by the compiler.
Imagine you have two source files:
File X.py
def X1:
return "x1"
from Y import Y2
def X2:
return "x2"
File Y.py
def Y1:
return "y1"
from X import X1
def Y2:
return "y2"
Now suppose you compile file X.py. The compiler begins by defining the method X1, and then hits the import statement in X.py. This causes the compiler to pause compilation of X.py and begin compiling Y.py. Shortly thereafter the compiler hits the import statement in Y.py. Since X.py is already in the module table, Python uses the existing incomplete X.py symbol table to satisfy any references requested. Any symbols appearing before the import statement in X.py are now in the symbol table, but any symbols after are not. Since X1 now appears before the import statement, it is successfully imported. Python then resumes compiling Y.py. In doing so it defines Y2 and finishes compiling Y.py. It then resumes compilation of X.py, and finds Y2 in the Y.py symbol table. Compilation eventually completes w/o error.
Something very different happens if you attempt to compile Y.py from the command line. While compiling Y.py, the compiler hits the import statement before it defines Y2. Then it starts compiling X.py. Soon it hits the import statement in X.py that requires Y2. But Y2 is undefined, so the compile fails.
Please note that if you modify X.py to import Y1, the compile will always succeed, no matter which file you compile. However if you modify file Y.py to import symbol X2, neither file will compile.
Any time when module X, or any module imported by X might import the current module, do NOT use:
from X import Y
Any time you think there may be a circular import you should also avoid compile time references to variables in other modules. Consider the innocent looking code:
import X
z = X.Y
Suppose module X imports this module before this module imports X. Further suppose Y is defined in X after the import statement. Then Y will not be defined when this module is imported, and you will get a compile error. If this module imports Y first, you can get away with it. But when one of your co-workers innocently changes the order of definitions in a third module, the code will break.
In some cases you can resolve circular dependencies by moving an import statement down below symbol definitions needed by other modules. In the examples above, definitions before the import statement never fail. Definitions after the import statement sometimes fail, depending on the order of compilation. You can even put import statements at the end of a file, so long as none of the imported symbols are needed at compile time.
Note that moving import statements down in a module obscures what you are doing. Compensate for this with a comment at the top of your module something like the following:
#import X (actual import moved down to avoid circular dependency)
In general this is a bad practice, but sometimes it is difficult to avoid.
About your command line:
root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save
You are already authenticated as root
so sudo
is redundant there.
You are missing the -j
or --jump
just before the ACCEPT
parameter (just tought that was a typo and you are inserting it correctly).
About yout question:
If you are inserting the iptables
rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.
If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:
check your vmachine network settings and:
if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.
if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.
if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.
Hope this helps.
You have two choices: stash your changes:
git stash
then later to get them back:
git stash apply
or put your changes on a branch so you can get the remote branch and then merge your changes onto it. That's one of the greatest things about git: you can make a branch, commit to it, then fetch other changes on to the branch you were on.
You say it doesn't make any sense, but you are only doing it so you can merge them at will after doing the pull. Obviously your other choice is to commit on your copy of the branch and then do the pull. The presumption is you either don't want to do that (in which case I am puzzled that you don't want a branch) or you are afraid of conflicts.
iptalbes tool relies on a kernel module interacting with netfilter to control network traffic.
This error happens while iptalbes cannot found that module in kernel, so iptables suggest you to upgrade it :)
Perhaps iptables or your kernel needs to be upgraded.
However in most cases it's just the module not added to kernel or being banned, try this command to check whether be banned:
cd /etc/modprobe.d/ && grep -nr iptable_nat
if the command shows any rule matched, such as blacklist iptable_nat
or install iptable_nat /bin/true
, delete it. Since iptalbes will cost some performance, it's not strange to ban it while not necessary.
If nothing found in blacklist, try add iptable-nat to the kernal manual:
modprobe iptable-nat
If all of above not works, you can consider really upgrade your kernal...
I think you are not configured properly,
if you are using XAMPP then you can easily send mail from localhost.
for example you can configure C:\xampp\php\php.ini
and c:\xampp\sendmail\sendmail.ini
for gmail to send mail.
in C:\xampp\php\php.ini
find extension=php_openssl.dll
and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
in php.ini file find [mail function]
and change
SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(use the above send mail path only and it will work)
Now Open C:\xampp\sendmail\sendmail.ini
. Replace all the existing code in sendmail.ini with following code
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]
Now you have done!! create php file with mail function and send mail from localhost.
Update
First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()
).
You can set the following settings in your PHP.ini:
ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");
Example:
iptables -A INPUT -j LOG --log-prefix "INPUT:DROP:" --log-level 6
iptables -A INPUT -j DROP
Log Exampe:
Feb 19 14:18:06 servername kernel: INPUT:DROP:IN=eth1 OUT= MAC=aa:bb:cc:dd:ee:ff:11:22:33:44:55:66:77:88 SRC=x.x.x.x DST=x.x.x.x LEN=48 TOS=0x00 PREC=0x00 TTL=117 ID=x PROTO=TCP SPT=x DPT=x WINDOW=x RES=0x00 SYN URGP=0
Other options:
LOG
Turn on kernel logging of matching packets. When this option
is set for a rule, the Linux kernel will print some
information on all matching packets
(like most IP header fields) via the kernel log (where it can
be read with dmesg or syslogd(8)). This is a "non-terminating
target", i.e. rule traversal
continues at the next rule. So if you want to LOG the packets
you refuse, use two separate rules with the same matching
criteria, first using target LOG
then DROP (or REJECT).
--log-level level
Level of logging (numeric or see syslog.conf(5)).
--log-prefix prefix
Prefix log messages with the specified prefix; up to 29
letters long, and useful for distinguishing messages in
the logs.
--log-tcp-sequence
Log TCP sequence numbers. This is a security risk if the
log is readable by users.
--log-tcp-options
Log options from the TCP packet header.
--log-ip-options
Log options from the IP packet header.
--log-uid
Log the userid of the process which generated the packet.
I ran into this issue when I had defined the module in the Angular controller but neglected to set the app name in my HTML file. For example:
<html ng-app>
instead of the correct:
<html ng-app="myApp">
when I had defined something like:
angular.module('myApp', []).controller(...
and referenced it in my HTML file.
for me, the problem was from require('jquery-validation')
i added in the begging of that js file which Validate method used which is necessary as an npm module
unfortunately, when web pack compiles the js files, they aren't in order, so that the validate method is before defining it! and the error comes
so better to use another js file for compiling this library or use local validate method file or even using CDN but in all cases make sure you attached jquery before
Use numpy.dot
or a.dot(b)
. See the documentation here.
>>> a = np.array([[ 5, 1 ,3],
[ 1, 1 ,1],
[ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])
This occurs because numpy arrays are not matrices, and the standard operations *, +, -, /
work element-wise on arrays. Instead, you could try using numpy.matrix
, and *
will be treated like matrix multiplication.
Also know there are other options:
As noted below, if using python3.5+ the @
operator works as you'd expect:
>>> print(a @ b)
array([16, 6, 8])
If you want overkill, you can use numpy.einsum
. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.
>>> np.einsum('ji,i->j', a, b)
array([16, 6, 8])
As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul
, which works like numpy.dot
with two major exceptions: no scalar multiplication but it works with stacks of matrices.
>>> np.matmul(a, b)
array([16, 6, 8])
numpy.inner
functions the same way as numpy.dot
for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).
>>> np.inner(a, b)
array([16, 6, 8])
# Beware using for matrix-matrix multiplication though!
>>> b = a.T
>>> np.dot(a, b)
array([[35, 9, 10],
[ 9, 3, 4],
[10, 4, 6]])
>>> np.inner(a, b)
array([[29, 12, 19],
[ 7, 4, 5],
[ 8, 5, 6]])
If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot
with the optional argument axes=1
:
>>> np.tensordot(a, b, axes=1)
array([16, 6, 8])
Don't use numpy.vdot
if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m
vs n
).
Found my solution on Apache/2.2.15 (Unix).

Right below the RewriteEngine On
line, add:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R] # <- for test, for prod use [L,R=301]
to enforce a no-trailing-slash policy.
To enforce a trailing-slash policy:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])$ /$1/ [L,R] # <- for test, for prod use [L,R=301]
EDIT: commented the R=301
parts because, as explained in a comment:
Be careful with that
R=301
! Having it there makes many browsers cache the .htaccess-file indefinitely: It somehow becomes irreversible if you can't clear the browser-cache on all machines that opened it. When testing, better go with simpleR
orR=302
After you've completed your tests, you can use R=301
.
You have two options,
-If you want the value:
Dim MyValue as Variant ' or string/date/long/...
MyValue = ThisWorkbook.Sheets(1).Range("A1").Value
-if you want the cell object:
Dim oCell as Range ' or object (but then you'll miss out on intellisense), and both can also contain more than one cell.
Set oCell = ThisWorkbook.Sheets(1).Range("A1")
You need to use quote marks.
font-family: "Comic Sans MS", cursive, sans-serif;
Although you really really shouldn't use comic sans. The font has massive stigma attached to it's use; it's not seen as professional at all.
Suppose your "Don't Check" list is on Sheet2 in cells A1:A100
, say, and your current client IDs are in Sheet1 in Column A.
What you would do is:

=ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0))
and select how you want those rows formattedAnd that should do the trick.
Android Studio 2.2 came out with the ability to use ndk-build and cMake. Though, we had to wait til 2.2.3 for the Application.mk support. I've tried it, it works...though, my variables aren't showing up in the debugger. I can still query them via command line though.
You need to do something like this:
externalNativeBuild{
ndkBuild{
path "Android.mk"
}
}
defaultConfig {
externalNativeBuild{
ndkBuild {
arguments "NDK_APPLICATION_MK:=Application.mk"
cFlags "-DTEST_C_FLAG1" "-DTEST_C_FLAG2"
cppFlags "-DTEST_CPP_FLAG2" "-DTEST_CPP_FLAG2"
abiFilters "armeabi-v7a", "armeabi"
}
}
}
See http://tools.android.com/tech-docs/external-c-builds
NB: The extra nesting of externalNativeBuild
inside defaultConfig
was a breaking change introduced with Android Studio 2.2 Preview 5 (July 8, 2016). See the release notes at the above link.
This is usually caused by an aborted connect. You can verify this by checking the status:
mysql> SHOW GLOBAL STATUS LIKE 'Aborted_connects';
If this counter keeps increasing as you get the lost connections, that's a sign you're having a problem during connect.
One remedy that seems to work in many cases is to increase the timeout. A suggested value is 10 seconds:
mysql> SET GLOBAL connect_timeout = 10;
Another common cause of connect timeouts is the reverse-DNS lookup that is necessary when authenticating clients. It is recommended to run MySQL with the config variable in my.cnf:
[mysqld]
skip-name-resolve
This means that your GRANT statements need to be based on IP address rather than hostname.
I also found this report from 2012 at the f5.com site (now protected by login, but I got it through Google cache)
It is likely the proxy will not work unless you are running BIG-IP 11.1 and MySQL 5.1, which were the versions I tested against. The MySQL protocol has a habit of changing.
I suggest you contact F5 Support and confirm that you are using a supported combination of versions.
I solved the problem by installing the google play services package in sdk manager.
After it, create a new application & in the build.gradle add this
compile 'com.google.android.gms:play-services:4.3.+'
Like this
dependencies {
compile 'com.android.support:appcompat-v7:+'
compile 'com.google.android.gms:play-services:4.3.+'
}
@media queries serve this purpose. Here's an example:
@media only screen and (max-width: 991px) and (min-width: 769px){
/* CSS that should be displayed if width is equal to or less than 991px and larger
than 768px goes here */
}
@media only screen and (max-width: 991px){
/* CSS that should be displayed if width is equal to or less than 991px goes here */
}
You'll need to add a firewall rule to open inbound access to tcp:9090
to your instances. If you have more than the two instances, and you only want to open 9090 to those two, you'll want to make sure that there is a tag that those two instances share. You can add or update tags via the console or the command-line; I'd recommend using the GUI for that if needed because it handles the read-modify-write cycle with setinstancetags
.
If you want to open port 9090 to all instances, you can create a firewall rule like:
gcutil addfirewall allow-9090 --allowed=tcp:9090
which will apply to all of your instances.
If you only want to open port 9090 to the two instances that are serving your application, make sure that they have a tag like my-app
, and then add a firewall like so:
gcutil addfirewall my-app-9090 --allowed=tcp:9090 --target_tags=my-app
You can read more about creating and managing firewalls in GCE here.
I noticed that Pandas for example will return 'nan' for blank values. Since it's not a string you need to convert it to one in order to match it. For example:
ulist = df.column1.unique() #create a list from a column with Pandas which
for loc in ulist:
loc = str(loc) #here 'nan' is converted to a string to compare with if
if loc != 'nan':
print(loc)
This question has been addressed, in a slightly different form, at length, here:
But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:
Matasano's article on this is famous, but the lessons contained therein are pretty important:
To summarize:
<script>
function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
And to add a corollary of my own:
This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!
First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.
This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.
The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.
This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!
The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.
Is Digest authentication possible with jQuery?
A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.
Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.
http://tools.ietf.org/html/rfc5849
Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?
JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.
The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.
This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.
The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.
To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.
It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX
". Many of these policies are pretty good ideas.
However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/
The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.
tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.
The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?
Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.
It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.
Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:
Aside from that, though, it's no different from Token Auth, really.
This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.
OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."
The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."
Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.
There are two ways that OAuth 2.0 can help you:
But when it comes down to it, you're just... using tokens.
So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"
And the answer is: do whatever makes you happy.
The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.
The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.

on which ever row you like. Here's a fiddle.
Of course, as people have mentioned, you can do this via an id, or class, or some other means if you wish.
To add to the excellent list (given by @CodeCowboyOrg) of situations where OPTION(RECOMPILE) can be very helpful,
@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.
.box {_x000D_
width: 500px;_x000D_
height: 100px;_x000D_
border: solid 5px #000;_x000D_
border-color: transparent transparent #000 transparent;_x000D_
border-radius: 0 0 240px 50%/60px;_x000D_
}
_x000D_
<div class="box"></div>
_x000D_
Ok, so very important to realize the implications here.
Docs say that SSL over 465 is NOT supported in SmtpClient.
Seems like you have no choice but to use STARTTLS which may not be supported by your mail host. You may have to use a different library if your host requires use of SSL over 465.
Quoted from http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.enablessl(v=vs.110).aspx
The SmtpClient class only supports the SMTP Service Extension for Secure SMTP over Transport Layer Security as defined in RFC 3207. In this mode, the SMTP session begins on an unencrypted channel, then a STARTTLS command is issued by the client to the server to switch to secure communication using SSL. See RFC 3207 published by the Internet Engineering Task Force (IETF) for more information.
An alternate connection method is where an SSL session is established up front before any protocol commands are sent. This connection method is sometimes called SMTP/SSL, SMTP over SSL, or SMTPS and by default uses port 465. This alternate connection method using SSL is not currently supported.
Bootstrap has 3 lines of CSS, within your bootstrap.css generated file that control the placeholder text color:
.form-control::-moz-placeholder {
color: #999999;
opacity: 1;
}
.form-control:-ms-input-placeholder {
color: #999999;
}
.form-control::-webkit-input-placeholder {
color: #999999;
}
Now if you add this to your own CSS file it won't override bootstrap's because it is less specific. So assmuning your form inside a then add that to your CSS:
form .form-control::-moz-placeholder {
color: #fff;
opacity: 1;
}
form .form-control:-ms-input-placeholder {
color: #fff;
}
form .form-control::-webkit-input-placeholder {
color: #fff;
}
Voila that will override bootstrap's CSS.
In Bootstrap 3.3.x make sure you use the scrollspy JavaScript capability to track active elements. It's easy to include it in your HTML. Just do the following:
<body data-spy="scroll" data-target="Id or class of the element you want to track">
In most cases I usually track active elements on my navbar, so I do the following:
<body data-spy="scroll" data-target=".navbar-fixed-top" >
Now in your CSS you can target .navbar-fixed-top .active a
:
.navbar-fixed-top .active a {
// Put in some styling
}
This should work if you are tracking active li elements in your top fixed navigation bar.
See this example:
$(document).ready(function(){
$(".dropdown-toggle").css({
"color": "#212529",
"background-color": "#ffc107",
"border-color": "#ffc107"
});
$(".multiselect-selected-text").text('Select Tags');
});
Try to change where Member class
public function users() {
return $this->hasOne('User');
}
return $this->belongsTo('User');
Running this command solved it for me:
php artisan view:clear
I guess a blank error page was some how cached. Had to clear the caches.
In my case I only need to add to project's build.gradle file:

exclude 'META-INF/license.txt'
}
...
}
Make sure that the htaccess file is readable by apache:
chmod 644 /var/www/abc/.htaccess
And make sure the directory it's in is readable and executable:
chmod 755 /var/www/abc/
The CSS property you are looking for is padding. The problem with padding is that it adds to the width of the original element, so if you have a div with a width of 300px, and add 10px of padding to it, the width will now be 320px (10px on the left and 10px on the right).
To prevent this you can add box-sizing: border-box; to the div, this makes it maintain the designated width, even if you add padding. So your CSS would look like this:
div {
box-sizing: border-box;
padding: 10px;
}
you can read more about box-sizing and it's overall browser support here:
"location" directive should be inside a 'server' directive, e.g.
server {
listen 8765;
location / {
resolver 8.8.8.8;
proxy_pass http://$http_host$uri$is_args$args;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
This code works. I have a date input field that has been set to read only which forces the user to select from the calendar.
for a start date:
var updateInput = "var input = document.getElementById('startDateInput');" +
"input.value = '18-Jan-2016';" +
"angular.element(input).scope().$apply(function(s) { s.$parent..searchForm[input.name].$setViewValue(input.value);})";
browser.executeScript(updateInput);
for an end date:
var updateInput = "var input = document.getElementById('endDateInput');" +
"input.value = '22-Jan-2016';" +
"angular.element(input).scope().$apply(function(s) { s.$parent.searchForm[input.name].$setViewValue(input.value);})";
browser.executeScript(updateInput);

if the current thread is killed and you use Thread.Sleep
and it is executing then you might get a ThreadAbortException

With Task.Delay
you can always provide a cancellation token and gracefully kill it. Thats one reason I would choose Task.Delay

I also agree efficiency is not paramount in this case.
As @page with pagenumbers don't work in browsers for now I was looking for alternatives.
I've found an answer posted by Oliver Kohll.
I'll repost it here so everyone could find it more easily:
For this answer we are not using @page, which is a pure CSS answer, but work in FireFox 20+ versions. Here is the link of an example.
The CSS is:
#content {
display: table;
}
#pageFooter {
display: table-footer-group;
}
#pageFooter:after {
counter-increment: page;
content: counter(page);
}
And the HTML code is:
<div id="content">
<div id="pageFooter">Page </div>
multi-page content here...
</div>
This way you can customize your page number by editing parametrs to #pageFooter. My example:
#pageFooter:after {
counter-increment: page;
content:"Page " counter(page);
left: 0;
top: 100%;
white-space: nowrap;
z-index: 20;
-moz-border-radius: 5px;
-moz-box-shadow: 0px 0px 4px #222;
background-image: -moz-linear-gradient(top, #eeeeee, #cccccc);
}
This trick worked for me fine. Hope it will help you.
Your code:
rules: {
phoneNumber: {
matches: "[0-9]+", // <-- no such method called "matches"!
minlength:10,
maxlength:10
}
}
There is no such callback function, option, method, or rule called matches
anywhere within the jQuery Validate plugin. (EDIT: OP failed to mention that matches
is his custom method.)
However, within the additional-methods.js
file, there are several phone number validation methods you can use. The one called phoneUS
should satisfy your pattern. Since the rule already validates the length, minlength
and maxlength
are redundantly unnecessary. It's also much more comprehensive in that area codes and prefixes can not start with a 1
.
rules: {
phoneNumber: {
phoneUS: true
}
}
DEMO: http://jsfiddle.net/eWhkv/
If, for whatever reason, you just need the regex for use in another method, you can take it from here...
jQuery.validator.addMethod("phoneUS", function(phone_number, element) {
phone_number = phone_number.replace(/\s+/g, "");
return this.optional(element) || phone_number.length > 9 &&
phone_number.match(/^(\+?1-?)?(\([2-9]\d{2}\)|[2-9]\d{2})-?[2-9]\d{2}-?\d{4}$/);
}, "Please specify a valid phone number");

You can use my plugin waitForImages to handle this...
$(document).waitForImages(function() {
// Loaded.
});
The advantage of this is you can localise it to one ancestor element and it can optionally detect images referenced in the CSS.
This is just the tip of the iceberg though, check the documentation for more functionality.
getClass().getResourcesAsStream()
works fine on Android. Just make sure the file you are trying to open is correctly embedded in your APK (open the APK as ZIP).
Normally on Android you put such files in the assets
directory. So if you put the raw_resources.dat
in the assets
subdirectory of your project, it will end up in the assets
directory in the APK and you can use:
getClass().getResourcesAsStream("/assets/raw_resources.dat");
It is also possible to customize the build process so that the file doesn't land in the assets
directory in the APK.
This works!

The player_api will be deprecated on Jun 25, 2015. For play youtube videos there is a new api IFRAME_API
It looks like the following code:

<div id="player"></div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',

}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {

If you want to add plots to your Jupyter notebook, then %matplotlib inline
is a standard solution. And there are other magic commands will use matplotlib
interactively within Jupyter.
%matplotlib
: any plt
plot command will now cause a figure window to open, and further commands can be run to update the plot. Some changes will not draw automatically, to force an update, use plt.draw()
%matplotlib notebook
: will lead to interactive plots embedded within the notebook, you can zoom and resize the figure
%matplotlib inline
: only draw static images in the notebook
Converting to double can be done by casting an int to a double:
You can convert an int to a double by using this mechnism like so:
int i = 3; // i is 3
double d = (double) i; // d = 3.0
Alternative (using Java's automatic type recognition):
double d = 1.0 * i; // d = 3.0
Implementing this in your code would be something like:
double firstSolution = ((double)(b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21));
double secondSolution = ((double)(b2 * a11 - b1 * a21) / (double)(a11 * a22 - a12 * a21));
Alternatively you can use a hard-parameter of type double (1.0) to have java to the work for you, like so:
double firstSolution = ((1.0 * (b1 * a22 - b2 * a12)) / (1.0 * (a11 * a22 - a12 * a21)));
double secondSolution = ((1.0 * (b2 * a11 - b1 * a21)) / (1.0 * (a11 * a22 - a12 * a21)));
Good luck.

PostgreSQL is integrated in Server.app available through the App Store in Mac OS X v10.8 (Mountain Lion). That means that it is already configured, and you only need to launch it, and then create users and databases.
Tip: Do not start with defining $PGDATA and so on. Take file locations as is.
You would have this file: /Library/Server/PostgreSQL/Config/org.postgresql.postgres.plist
To start:
sudo serveradmin start postgres
Process started with arguments:
/Applications/Server.app/Contents/ServerRoot/usr/bin/postgres_real -D /Library/Server/PostgreSQL/Data -c listen_addresses=127.0.0.1,::1 -c log_connections=on -c log_directory=/Library/Logs/PostgreSQL -c log_filename=PostgreSQL.log -c log_line_prefix=%t -c log_lock_waits=on -c log_statement=ddl -c logging_collector=on -c unix_socket_directory=/private/var/pgsql_socket -c unix_socket_group=_postgres -c unix_socket_permissions=0770
You can sudo:
sudo -u _postgres psql template1
Or connect:
psql -h localhost -U _postgres postgres
You can find the data directory, version, running status and so forth with
sudo serveradmin fullstatus postgres
If expression
returns a boolean, you can just return the result of it.
Example
return (a > b)
I'm forced to post this as an answer instead of a comment due to low reputation.
I had a similar problem to Matteo. The difference being that I had no map from my first x-axis to my second x-axis, only the x-values themselves. So I wanted to set the data on my second x-axis directly, not the ticks, however, there is no axes.set_xdata
. I was able to use Dhara's answer to do this with a modification:
ax2.lines = []
instead of using:
ax2.cla()
When in use also cleared my plot from ax1

Bootstrap 4 has spacing utilities to handle this https://getbootstrap.com/docs/4.0/utilities/spacing/
.mt-0 {
margin-top: 0 !important;
}
--
ORIGINAL ANSWER
If you are using SASS, this is what I normally do.
$margins: (xs: 0.5rem, sm: 1rem, md: 1.5rem, lg: 2rem, xl: 2.5rem);
@each $name, $value in $margins {
.margin-top-#{$name} {
margin-top: $value;
}
.margin-bottom-#{$name} {
margin-bottom: $value;
}
}
so you can later use margin-top-xs
for example
Can I pass parameters by reference in Java?
No.
Why ? Java has only one mode of passing arguments to methods: by value.
Note:
For primitives this is easy to understand: you get a copy of the value.
For all other you get a copy of the reference and this is called also passing by value.
It is all in this picture:
This tutorial worked for me, resolving my issues with /usr/local/bin permission issues and php-cli (which composer requires, and may aliased differently on shared hosting).
First run these commands to download and install composer:
cd ~
mkdir bin
mkdir bin/composer
curl -sS https://getcomposer.org/installer | php
mv composer.phar bin/composer
Determine the location of your php-cli (needed later on):
which php-cli
(If the above fails, use which php
)
It should return the path, such as /usr/bin/php-cli, /usr/php/54/usr/bin/php-cli, etc.
edit ~/.bashrc and make sure this line is at the top, adding it if it is not:
[ -z "$PS1" ] && return
and then add this alias to the bottom (using the php-cli path that you determined earlier):
alias composer="/usr/bin/php-cli ~/bin/composer/composer.phar"
Finish with these commands:
source ~/.bashrc
composer --version
Call the toISOString()
method:
var dt = new Date("30 July 2010 15:05 UTC");

All you need is Enum.Parse.
As the other answers mentioned, dispatch_async from the main thread is fine.
However, depending on your use case, there is a side effect that you may consider a disadvantage: since the block is scheduled on a queue, it won't execute until control goes back to the run loop, which will have the effect of delaying your block's execution.
For example,
NSLog(@"before dispatch async");
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"inside dispatch async block main thread from main thread");
});
NSLog(@"after dispatch async");
Will print out:
before dispatch async
after dispatch async
inside dispatch async block main thread from main thread
For this reason, if you were expecting the block to execute in-between the outer NSLog's, dispatch_async would not help you.
I had to COPY
and untar java package in my docker image.
When I compared the docker image size created using ADD it was 180MB bigger than the one created using COPY, tar -xzf *.tar.gz and rm *.tar.gz
This means that although ADD removes the tar file, it is still kept somewhere. And its making the image bigger!!
^[0-9]{1,6}$
should do it. I don't know VB.NET good enough to know if it's the same there.
For examples, have a look at the Wikipedia.
If you have @oneToOne
mapping set to FetchType.LAZY
and you use second query (because you need Department objects to be loaded as part of Employee objects) what Hibernate will do is, it will issue queries to fetch Department objects for every individual Employee object it fetches from DB.
Later, in the code you might access Department objects via Employee to Department single-valued association and Hibernate will not issue any query to fetch Department object for the given Employee.
Remember, Hibernate still issues queries equal to the number of Employees it has fetched. Hibernate will issue same number of queries in both above queries, if you wish to access Department objects of all Employee objects
When you use PropertyConfigurator.configure(String configFilename), they are the following operation in the log4j library.
Properties props = new Properties();
FileInputStream istream = null;
try {
istream = new FileInputStream(configFileName);
props.load(istream);
istream.close();
}
catch (Exception e) {
...
It fails in reading because it looks for "Log4j.properties" from the current directory where the application is executed.
How about the way that it changes the reading part of the property file as follows, and puts "log4j.properties" on the directory to which the CLASSPATH is set.
ClassLoader loader = Thread.currentThread().getContextClassLoader();
URL url = loader.getResource("log4j.properties");
PropertyConfigurator.configure(url);
Another method of putting "Log4j.properties" in the jar file exists.
jar xvf [YourApplication].jar log4j.properties
If you are needing to use CSS with the jQuery .animate()
function, you can use set the duration.
$("#my_image").css({
'left':'1000px',
6000, ''
});
We have the duration property set to 6000.
This will set the time in thousandth of seconds: 6 seconds.
After the duration our next property "easing" changes how our CSS happens.
We have our positioning set to absolute.
There are two default ones to the absolute function: 'linear' and 'swing'.
In this example I am using linear.
It allows for it to use a even pace.
The other 'swing' allows for a exponential speed increase.
There are a bunch of really cool properties to use with animate like bounce, etc.
$(document).ready(function(){
$("#my_image").css({
'height': '100px',
'width':'100px',
'background-color':'#0000EE',
'position':'absolute'
});// property than value
$("#my_image").animate({
'left':'1000px'
},6000, 'linear', function(){
alert("Done Animating");
});
});
A trivial approach would be to replace
<[^>]*>
with nothing. But depending on how ill-structured your input is that may well fail.
Here's another C version. It defines a macro called wicked_cast()
for inline type punning via C99 union literals and the non-standard __typeof__
operator.
#include <limits.h>
#if UCHAR_MAX == UINT_MAX
#error endianness irrelevant as sizeof(int) == 1
#endif
#define wicked_cast(TYPE, VALUE) \
(((union { __typeof__(VALUE) src; TYPE dest; }){ .src = VALUE }).dest)
_Bool is_little_endian(void)
{
return wicked_cast(unsigned char, 1u);
}
If integers are single-byte values, endianness makes no sense and a compile-time error will be generated.
if your image is purely decorative, then it might be a more semantic solution to use it as a background-image. You can then specify the position of the background
background-position: center center;
If it is not decorative and constitutes valuable information then the img tag is justified. What you need to do in such case is style the containing div with the following properties:
div{
display: table-cell; vertical-align: middle
}

Setting the dialog cancelable to be false is enough, and either you touch outside of the alert dialog or click the back button will make the alert dialog disappear. So use this one:
setCancelable(false)
And the other function is not necessary anymore:
dialog.setCanceledOnTouchOutside(false);
If you are creating a temporary dialog and wondering there to put this line of code, here is an example:
new AlertDialog.Builder(this)
.setTitle("Trial Version")
.setCancelable(false)
.setMessage("You are using trial version!")
.setIcon(R.drawable.time_left)
.setPositiveButton(android.R.string.yes, null).show();

From other post:
find /c "string" file >NUL
if %errorlevel% equ 1 goto notfound
echo found
goto done
:notfound
echo notfound
goto done
:done
Use the /i switch when you want case insensitive checking:
find /i /c "string" file >NUL
Or something like: if not found write to file.
find /c "%%P" file.txt || ( echo %%P >> newfile.txt )
Or something like: if found write to file.
find /c "%%P" file.txt && ( echo %%P >> newfile.txt )
Or something like:
find /c "%%P" file.txt && ( echo found ) || ( echo not found )
- Line Feed and Carriage Return
These HTML entities will insert a new line or carriage return inside a text area.
While this is an old question, it's worth updating the answer to C++17. In the standard library there is now the templated function std::size()
, which returns the number of elements in both a std container or a C-style array. For example:
#include <iterator>
uint32_t data[] = {10, 20, 30, 40};
auto dataSize = std::size(data);
// dataSize == 4
There are problems with some data. Consider:
as.double(as.character("2.e")) # This results in 2
Another solution:
get_numbers <- function(X) {
X[toupper(X) != tolower(X)] <- NA
return(as.double(as.character(X)))
}
As long as pip lives within the scripts folder you can run
python -m pip ....
This will tell python to get pip from inside the scripts folder. This is also a good way to have both python2.7 and pyhton3.5 on you computer and have them in different locations. I currently have both python2 and pyhton3 installed on windows. When I type python
it defaults to python2. But if I type python3
I can use python3. (I also had to change the python.exe file for python3 to "python3.exe")If I need to install flask for python 2 I can run
python -m pip install flask
and it will be installed in the pyhton2 folder, but if I need flask for python 3 I run:
python3 -m pip install flask
and I now have it in the python3 folder
The problem with all the approaches based on gethostbyname is that you will not get all IP addresses assigned to a particular machine. Servers usually have more than one adapter.
Here is an example of how you can iterate through all Ipv4 and Ipv6 addresses on the host machine:
void ListIpAddresses(IpAddresses& ipAddrs)
{
IP_ADAPTER_ADDRESSES* adapter_addresses(NULL);
IP_ADAPTER_ADDRESSES* adapter(NULL);
// Start with a 16 KB buffer and resize if needed -
// multiple attempts in case interfaces change while
// we are in the middle of querying them.
DWORD adapter_addresses_buffer_size = 16 * KB;
for (int attempts = 0; attempts != 3; ++attempts)
{
adapter_addresses = (IP_ADAPTER_ADDRESSES*)malloc(adapter_addresses_buffer_size);
assert(adapter_addresses);
DWORD error = ::GetAdaptersAddresses(
AF_UNSPEC,
GAA_FLAG_SKIP_ANYCAST |
GAA_FLAG_SKIP_MULTICAST |
GAA_FLAG_SKIP_DNS_SERVER |
GAA_FLAG_SKIP_FRIENDLY_NAME,
NULL,
adapter_addresses,
&adapter_addresses_buffer_size);
if (ERROR_SUCCESS == error)
{
// We're done here, people!
break;
}
else if (ERROR_BUFFER_OVERFLOW == error)
{
// Try again with the new size
free(adapter_addresses);
adapter_addresses = NULL;
continue;
}
else
{
// Unexpected error code - log and throw
free(adapter_addresses);
adapter_addresses = NULL;
// @todo
LOG_AND_THROW_HERE();
}
}
// Iterate through all of the adapters
for (adapter = adapter_addresses; NULL != adapter; adapter = adapter->Next)
{
// Skip loopback adapters
if (IF_TYPE_SOFTWARE_LOOPBACK == adapter->IfType)
{
continue;
}
// Parse all IPv4 and IPv6 addresses
for (
IP_ADAPTER_UNICAST_ADDRESS* address = adapter->FirstUnicastAddress;
NULL != address;
address = address->Next)
{
auto family = address->Address.lpSockaddr->sa_family;
if (AF_INET == family)
{
// IPv4
SOCKADDR_IN* ipv4 = reinterpret_cast<SOCKADDR_IN*>(address->Address.lpSockaddr);
char str_buffer[INET_ADDRSTRLEN] = {0};
inet_ntop(AF_INET, &(ipv4->sin_addr), str_buffer, INET_ADDRSTRLEN);
ipAddrs.mIpv4.push_back(str_buffer);
}
else if (AF_INET6 == family)
{

else if (0 == ipv6_str.find("2001:0:"))
{
is_special_use = true;

if (! (is_link_local || is_special_use))
{
ipAddrs.mIpv6.push_back(ipv6_str);
}
}
else
{
// Skip all other types of addresses
continue;

}
}
// Cleanup
free(adapter_addresses);
adapter_addresses = NULL;

I've checked almost all solutions from above and only with npm-run-all I was able to solve all problems. Main advantage over all other solution is an ability to run script with arguments.
{
"test:static-server": "cross-env NODE_ENV=test node server/testsServer.js",
"test:jest": "cross-env NODE_ENV=test jest",
"test": "run-p test:static-server \"test:jest -- {*}\" --",
"test:coverage": "npm run test -- --coverage",
"test:watch": "npm run test -- --watchAll",
}
Note
run-p
is shortcut fornpm-run-all --parallel
This allows me to run command with arguments like npm run test:watch -- Something
.
EDIT:
There is one more useful option for npm-run-all
:
-r, --race - - - - - - - Set the flag to kill all tasks when a task
finished with zero. This option is valid only
with 'parallel' option.
Add -r
to your npm-run-all
script to kill all processes when one finished with code 0
. This is especially useful when you run a HTTP server and another script that use the server.
"test": "run-p -r test:static-server \"test:jest -- {*}\" --",
Try SELECT CAST(field1 AS DECIMAL(10,2)) field1
and replace 10,2

Should you want to resort to using a plug-in, malihu-custom-scrollbar-plugin, could do the job. It performs an actual scroll, not just a jump. You can even specify the speed/momentum of scroll. It also lets you set up a menu (list of links to scroll to), which have their CSS changed based on whether the anchors-to-scroll-to are in viewport, and other useful features.
There are demo on the author's site and let our company site serve as a real-world example too.
Another options is Matteo Bicocchi's jQuery mb.extruder tabs plug-in: http://pupunzi.open-lab.com/mb-jquery-components/jquery-mb-extruder/
There is no guaranteed solution to this problem because the phone number is not physically stored on all SIM-cards, or broadcasted from the network to the phone. This is especially true in some countries which requires physical address verification, with number assignment only happening afterwards. Phone number assignment happens on the network - and can be changed without changing the SIM card or device (e.g. this is how porting is supported).
I know it is pain, but most likely the best solution is just to ask the user to enter his/her phone number once and store it.
This will work for Linux, for example if you want to check if banshee is running... (banshee is a music player)
import subprocess
def running_process(process):
"check if process is running. < process > is the name of the process."
proc = subprocess.Popen(["if pgrep " + process + " >/dev/null 2>&1; then echo 'True'; else echo 'False'; fi"], stdout=subprocess.PIPE, shell=True)
(Process_Existance, err) = proc.communicate()
return Process_Existance
# use the function
print running_process("banshee")
Here the async version.
public static Task<BitmapSource> ToBitmapSourceAsync(this Bitmap bitmap)
{
return Task.Run(() =>
{
using (System.IO.MemoryStream memory = new System.IO.MemoryStream())
{
bitmap.Save(memory, ImageFormat.Png);
memory.Position = 0;
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = memory;
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.EndInit();
bitmapImage.Freeze();
return bitmapImage as BitmapSource;
}
});
}
This worked for me, May help you too :

SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.
For more detail you can refer the link.
There are several ways, but using rename
will probably be the easiest.
Using one version of rename
:
rename 's/^fgh/jkl/' fgh*
Using another version of rename
(same as Judy2K's answer):
rename fgh jkl fgh*
You should check your platform's man page to see which of the above applies.
The attribute selectors are often used for inputs. This is the list of attribute selectors:
[title] All elements with the title attribute are selected.
[title=banana] All elements which have the 'banana' value of the title attribute.
[title~=banana] All elements which contain 'banana' in the value of the title attribute.
[title|=banana] All elements which value of the title attribute starts with 'banana'.
[title^=banana] All elements which value of the title attribute begins with 'banana'.
[title$=banana] All elements which value of the title attribute ends with 'banana'.
[title*=banana] All elements which value of the title attribute contains the substring 'banana'.
Reference: https://kolosek.com/css-selectors/

You can use Dialog to create this easily
create a Dialog instance using the context
Dialog dialog = new Dialog(contex);
You can design your layout as you like.
You can add this layout to your dialog by
dialog.setContentView(R.layout.popupview);//popup view is the layout you created
then you can access its content (textviews, etc.) by using findViewById
method
TextView txt = (TextView)dialog.findViewById(R.id.textbox);
you can add any text here. the text can be stored in the String.xml file in res\values.
txt.setText(getString(R.string.message));
then finally show the pop up menu
dialog.show();

The answer above is now obsolete with Unity 5 or newer. Use this instead!
GetComponent<Rigidbody2D>().AddForce(new Vector2(0,10), ForceMode2D.Impulse);
I also want to add that this leaves the jump height super private and only editable in the script, so this is what I did...
public float playerSpeed; //allows us to be able to change speed in Unity
public Vector2 jumpHeight;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update ()
{
transform.Translate(playerSpeed * Time.deltaTime, 0f, 0f); //makes player run
if (Input.GetMouseButtonDown(0) || Input.GetKeyDown(KeyCode.Space)) //makes player jump
{
GetComponent<Rigidbody2D>().AddForce(jumpHeight, ForceMode2D.Impulse);
This makes it to where you can edit the jump height in Unity itself without having to go back to the script.
Side note - I wanted to comment on the answer above, but I can't because I'm new here. :)

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user
, picked from your example), then the syntax is quite simple:
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin('a.user', 'u')
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
Since you are applying a condition on the joined result here, using a LEFT JOIN
or simply JOIN
is the same.
If no association is available, then the query looks like following
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin(
'User\Entity\User',
'u',
\Doctrine\ORM\Query\Expr\Join::WITH,
'a.user = u.id'
)
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
This will produce a resultset that looks like following:
array(
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
// ...
)
First use
git pull https://github.com/username/repository master
and then try

As stated in PostgreSQL docs here:
The SQL CASE expression is a generic conditional expression, similar to if/else statements in other programming languages.

The spread operator allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) are expected.
ECMAScript ES6 added a new operator that lets you do this in a more practical way: ...Spread Operator.
Example without using the apply
method:
function a(...args){_x000D_
b(...args);_x000D_
b(6, ...args, 8) // You can even add more elements_x000D_
}_x000D_
function b(){_x000D_
console.log(arguments)_x000D_
}_x000D_
_x000D_
a(1, 2, 3)
_x000D_
Note This snippet returns a syntax error if your browser still uses ES5.
Editor's note: Since the snippet uses console.log()
, you must open your browser's JS console to see the result - there will be no in-page result.
It will display this result:
In short, the spread operator can be used for different purposes if you're using arrays, so it can also be used for function arguments, you can see a similar example explained in the official docs: Rest parameters
There's better support for this now through conda-env
. You can, for example, now do:
name: sample_env
channels:
dependencies:
- requests
- bokeh>=0.10.0
- pip:
- "--editable=git+https://github.com/pythonforfacebook/facebook-sdk.git@8c0d34291aaafec00e02eaa71cc2a242790a0fcc#egg=facebook_sdk-master"
It's still calling pip under the covers, but you can now unify your conda and pip package specifications in a single environment.yml
file.
If you wanted to update your root environment with this file, you would need to save this to a file (for example, environment.yml
), then run the command: conda env update -f environment.yml
.
It's more likely that you would want to create a new environment:
conda env create -f environment.yml
(changed as supposed in the comments)

You can use multiselect
function for this.
CriteriaBuilder cb=session.getCriteriaBuilder();
CriteriaQuery<Object[]> cquery=cb.createQuery(Object[].class);
Root<Car> root=cquery.from(User.class);
cquery.multiselect(root.get("id"),root.get("Name"));
Query<Object[]> q=session.createQuery(cquery);
List<Object[]> list=q.getResultList();
System.out.println("id Name");
for (Object[] objects : list) {
System.out.println(objects[0]+" "+objects[1]);
}
This is supported by hibernate 5. createCriteria
is deprecated in further version of hibernate. So you can use criteria builder

You can delete the archive files and executable binaries that go install
(or go get
) produces for a package with go clean -i importpath...
. These normally reside under $GOPATH/pkg
and $GOPATH/bin
, respectively.
Be sure to include ...
on the importpath, since it appears that, if a package includes an executable, go clean -i
will only remove that and not archive files for subpackages, like gore/gocode
in the example below.
Source code then needs to be removed manually from $GOPATH/src
.
go clean
has an -n
flag for a dry run that prints what will be run without executing it, so you can be certain (see go help clean
). It also has a tempting -r
flag to recursively clean dependencies, which you probably don't want to actually use since you'll see from a dry run that it will delete lots of standard library archive files!
A complete example, which you could base a script on if you like:
$ go get -u github.com/motemen/gore

/Users/ches/src/go/bin/gore
$ go clean -i -n github.com/motemen/gore...

Since version 3.3 of ggplot2, we have access to the convenient after_stat()
function.
We can do something similar to @Andrew's answer, but without using the ..
syntax:
# original example data
mydata <- c("aa", "bb", NULL, "bb", "cc", "aa", "aa", "aa", "ee", NULL, "cc")
# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
y = after_stat(count/sum(count)))) +
geom_bar() +
scale_y_continuous(labels = scales::percent)
You can find all the "computed variables" available to use in the documentation of the geom_
and stat_
functions. For example, for geom_bar()
, you can access the count
and prop
variables. (See the documentation for computed variables.)
One comment about your NULL
values: they are ignored when you create the vector (i.e. you end up with a vector of length 9, not 11). If you really want to keep track of missing data, you will have to use NA
instead (ggplot2 will put NAs at the right end of the plot):
# use NA instead of NULL
mydata <- c("aa", "bb", NA, "bb", "cc", "aa", "aa", "aa", "ee", NA, "cc")
length(mydata)
#> [1] 11
# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
y = after_stat(count/sum(count)))) +
geom_bar() +
scale_y_continuous(labels = scales::percent)

On server side you just need to write simple file upload code to handle this request with echoing message you want to show to user as a response.
Yup, serialize/unserialize is what I've seen the most in many open source projects.
A further clarification to the use of DISTINCT to resolve error ORA-30926 in the general case:
You need to ensure that the set of data specified by the USING() clause has no duplicate values of the join columns, i.e. the columns in the ON() clause.
In OP's example where the USING clause only selects a key, it was sufficient to add DISTINCT to the USING clause. However, in the general case the USING clause may select a combination of key columns to match on and attribute columns to be used in the UPDATE ... SET clause. Therefore in the general case, adding DISTINCT to the USING clause will still allow different update rows for the same keys, in which case you will still get the ORA-30926 error.
This is an elaboration of DCookie's answer and point 3.1 in Tagar's answer, which from my experience may not be immediately obvious.
With jquery
$("div#id").append('<a href=#>Your LINK TITLE</a>')
With javascript
var new_a = document.createElement('a');
new_a.setAttribute("href", "link url here");
new_a.innerHTML = "your link text";
//add new link to the DOM
document.appendChild(new_a);
If you want to only trigger validation when the input looses focus you can use onBlur
Trivia: React <17 listens to blur
event and >=17 listens to focusout
event.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.
Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.
Additional entries pillaged from SD-6 feature-test list.
clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.
these slides had some features missing elsewhere.

You don't need JQuery, you can do it in JavaScript, Hope you get it.
To expand on Marian Udrea's answer:
In my scenario, I was trying to align the text with a material icon. There's something weird about material icons that prevented it from being aligned. None of the answers were working, until I added the vertical-align
to the icon element, instead of the parent element.
So, if the icon is 24px
in height:
.parent {
line-height: 24px; // Same as icon height
i.material-icons { // Only if you're using material icons
display: inline-flex;
vertical-align: top;
}
}

You don't need to iterate the array. Just:
>>> x = ['[email protected]', '[email protected]']
>>> x
['[email protected]', '[email protected]']
>>> x.remove('[email protected]')
>>> x
['[email protected]']
This will remove the first occurence that matches the string.
EDIT: After your edit, you still don't need to iterate over. Just do:
index = initial_list.index(item1)
del initial_list[index]
del other_list[index]
Consider a solution that will neatly handle arbitrarily many tables.
//ASSUMPTION: All tables must have the same columns
var tables = new List<DataTable>();
tables.Add(oneTableToRuleThemAll);
tables.Add(oneTableToFindThem);
tables.Add(oneTableToBringThemAll);
tables.Add(andInTheDarknessBindThem);
//Or in the real world, you might be getting a collection of tables from some abstracted data source.
//behold, a table too great and terrible to imagine
var theOneTable = tables.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();
Encapsulated into a helper for future reuse:
public static DataTable CombineDataTables(params DataTable[] args)
{
return args.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();
}
Just have a few tables declared in code?
var combined = CombineDataTables(dt1,dt2,dt3);
Want to combine into one of the existing tables instead of creating a new one?
dt1 = CombineDataTables(dt1,dt2,dt3);
Already have a collection of tables, instead of declared one by one?
//Pretend variable tables already exists
var tables = new[] { dt1, dt2, dt3 };
var combined = CombineDataTables(tables);
You could achieve that simply by wrapping the image by a <div>
and adding overflow: hidden
to that element:
<div class="img-wrapper">
<img src="..." />
</div>
.img-wrapper {
display: inline-block; /* change the default display type to inline-block */
overflow: hidden; /* hide the overflow */
}
Also it's worth noting that <img>
element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px
gap at the bottom of the image.
That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align
property to the image with a value other than baseline
.
Additionally for a better user experience, you could add transition
to the images.
Thus we'll end up with the following:
.img-wrapper img {
transition: all .2s ease;
vertical-align: middle;
}
Looks like something is wrong with your data, it isn't in the format you are expecting. It could be a new line character or a blank space in the data that is tinkering with your code.
One trick is to create an interface that extends a generic base interface...
public interface LoadFutures extends Map<UUID, Future<LoadResult>> {}
Then you can check it with instanceof before the cast...
Object obj = context.getAttribute(FUTURES);
if (!(obj instanceof LoadFutures)) {
String format = "Servlet context attribute \"%s\" is not of type "
+ "LoadFutures. Its type is %s.";
String msg = String.format(format, FUTURES, obj.getClass());
throw new RuntimeException(msg);
}
return (LoadFutures) obj;
As Matt has said, use Console.Write
. I would also recommend explicitly flushing the output, however - I believe WriteLine
does this automatically, but I'd seen oddities when just using Console.Write
and then waiting. So Matt's code becomes:
Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();

Use FileMode.Truncate
everytime you create the file. Also place the File.Create
inside a try
catch
.
First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.
For example,
> z <- factor(letters[c(3, 2, 3, 4)])
# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d
# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"
here, z
has 4 elements.
The index is 2, 1, 2, 3
in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.
Then, as.numeric
converts simply the index part of factor into numeric.
as.character
handles the index and levels, and generates character vector expressed by its level.
?as.numeric
says that Factors are handled by the default method.
The answer to my own question is, I think, to use tomcat7.exe:
cd $CATALINA_HOME
.\bin\service.bat install tomcat
.\bin\tomcat7.exe //US//tomcat7 --JvmMs=512 --JvmMx=1024 --JvmSs=1024
Also, you can launch the UI tool mentioned by BalusC without the system tray or using the installer with tomcat7w.exe
.\bin\tomcat7w.exe //ES//tomcat
An additional note to this:
Setting the --JvmXX parameters (through the UI tool or the command line) may not be enough. You may also need to specify the JVM memory values explicitly. From the command line it may look like this:
bin\tomcat7w.exe //US//tomcat7 --JavaOptions=-Xmx=1024;-Xms=512;..
Be careful not to override the other JavaOption values. You can try updating bin\service.bat or use the UI tool and append the java options (separate each value with a new line).
In Eclipse 3.3:
It's installed under your Eclipse workspace. Something like:
.metadata\.plugins\org.eclipse.core.resources\.projects\
within your workspace folder.
Under that folder is one folder per project. There's a file in there called .location, but it's binary.
So it looks like you can't do what you want, without interacting w/ Eclipse programmatically.
If you need to insert into a specific position in the array, you can do this:
case ADD_ITEM :
return {
...state,
arr: [
...state.arr.slice(0, action.pos),
action.newItem,
...state.arr.slice(action.pos),
],
}
There are multiple ways to write same logic. As it mentioned earlier, you can use object notation or simply expression. However, I think you should not that much logic in HTML. Hard to test and find issue. You can use a getter function to assign the class.
For Instance;
public getCustomCss() {
//Logic here;
if(this.x == this.y){
return 'class1'
}
if(this.x == this.z){
return 'class2'
}
}
<!-- HTML -->
<div [ngClass]="getCustomCss()"> Some prop</div>
//OR
get customCss() {
//Logic here;
if(this.x == this.y){
return 'class1'
}
if(this.x == this.z){
return 'class2'
}
}
<!-- HTML -->
<div [ngClass]="customCss"> Some prop</div>
It's much easier to just use jQuery, since this is just a task for university and you do not need to save code.
So, your code will look like:
function sendMyComment() {
$('#addComment').append('<input type="hidden" name="video_id" id="video_id" value="' + $('#video_id').text() + '"/><input type="hidden" name="video_time" id="video_time" value="' + $('#time').text() +'"/>');
$.ajax({
type: 'POST',
url: $('#addComment').attr('action'),
data: $('form').serialize(),
success: function(response) { ... },
});
}
The question doesn't address multiline strings, but here is how you would strip leading whitespace from a multiline string using python's standard library textwrap module. If we had a string like:
s = """
line 1 has 4 leading spaces
line 2 has 4 leading spaces
line 3 has 4 leading spaces
"""
if we print(s)
we would get output like:
>>> print(s)
this has 4 leading spaces 1
this has 4 leading spaces 2
this has 4 leading spaces 3
and if we used textwrap.dedent
:
>>> import textwrap
>>> print(textwrap.dedent(s))
this has 4 leading spaces 1
this has 4 leading spaces 2
this has 4 leading spaces 3
DateTime
inherits its equals
method from AbstractInstant
. It is implemented as such
public boolean equals(Object readableInstant) { // must be to fulfil ReadableInstant contract if (this == readableInstant) { return true; } if (readableInstant instanceof ReadableInstant == false) { return false; } ReadableInstant otherInstant = (ReadableInstant) readableInstant; return getMillis() == otherInstant.getMillis() && FieldUtils.equals(getChronology(), otherInstant.getChronology()); }
Notice the last line comparing chronology. It's possible your instances' chronologies are different.
Another option is to ensure the file is not open anywhere else on your machine.
I have the similar issue. You can use setTimeout() to avoid the double-click.
//some codes here above after the click then disable it
// also check here if there's an attribute disabled
// if there's an attribute disabled in the btn tag then // return. Convert that into js.
$('#btn1').prop("disabled", true);
setTimeout(function(){
$('#btn1').prop("disabled", false);
}, 300);
If it looks bad you can use CSS to change the appearance of selected sections.
Try this
$objPHPExcel = new PHPExcel(); $objPHPExcel->getProperties()->setCreator("Maarten Balliauw") ->setLastModifiedBy("Maarten Balliauw") ->setTitle("Office 2007 XLSX Test Document") ->setSubject("Office 2007 XLSX Test Document") ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.") ->setKeywords("office 2007 openxml php") ->setCategory("Test result file"); $objPHPExcel->setActiveSheetIndex(0); $sheet = $objPHPExcel->getActiveSheet(); $sheet->setCellValue('A1', 'No'); $sheet->setCellValue('B1', 'Job ID'); $sheet->setCellValue('C1', 'Job completed Date'); $sheet->setCellValue('D1', 'Job Archived Date'); $styleArray = array( 'font' => array( 'bold' => true ) ); $sheet->getStyle('A1')->applyFromArray($styleArray); $sheet->getStyle('B1')->applyFromArray($styleArray); $sheet->getStyle('C1')->applyFromArray($styleArray); $sheet->getStyle('D1')->applyFromArray($styleArray); $sheet->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 1);
This is give me output like below link.(https://www.screencast.com/t/ZkKFHbDq1le)
For Ubuntu 17.0 +
Adding to @netcoder answer above, If you are using Ubuntu 17+, installing libcurl header files is half of the solution. The installation path in ubuntu 17.0+ is different than the installation path in older Ubuntu version. After installing libcurl, you will still get the "cURL not found" error. You need to perform one extra step (as suggested by @minhajul in the OP comment section).
Add a symlink in /usr/include of the cURL installation folder (cURL installation path in Ubuntu 17.0.4 is /usr/include/x86_64-linux-gnu/curl).
My server was running Ubuntu 17.0.4, the commands to enable cURL support were
sudo apt-get install libcurl4-gnutls-dev
Then create a link to cURL installation
cd /usr/include
sudo ln -s x86_64-linux-gnu/curl
This may also happen if you have a faulty or accidental equation in your csv file. i.e - One of the cells in your csv file starts with an equals sign (=) (An excel equation) which will, in turn throw an error. If you fix, or remove this equation by getting rid of the equals sign, it should solve the ORA-06502 error.
Here you can find a good explanation on the difference between
Update both gem and dependencies:
bundle update gem-name
or
Update exclusively the gem:
bundle update --source gem-name
along with some nice examples of possible side-effects.
As @Tim's answer says, as of Bundler 1.14 the officially-supported way to this is with bundle update --conservative gem-name
.
In Github click the "Clone or download" button of the project you want to import --> download the ZIP file and unzip it. In Android Studio Go to File -> New Project -> Import Project and select the newly unzipped folder -> press OK. It will build the Gradle automatically.

I recommend second example , it is faster.
1- you need to close the block of the function with '}', which is missing.
2- the argument of querySelector may not be an empty string '' or ' '... Use '*' for all.
3- those arguments will return the needed value:
querySelector('*')
querySelector('input')
querySelector('input[name="pwd"]')
querySelector('[name="pwd"]')
It should be mentioned that the Accept
header tells the server something about what we are accepting back, whereas the relevant header in this context is Content-Type
It's often advisable to specify Content-Type
as application/json
when sending JSON. For curl the syntax is:
-H 'Content-Type: application/json'
So the complete curl command will be:
curl -H 'Content-Type: application/json' -H 'Accept: application/json' -X PUT -d '{"tags":["tag1","tag2"],"question":"Which band?","answers":[{"id":"a0","answer":"Answer1"},{"id":"a1","answer":"answer2"}]}' http://example.com/service`
Another way to wait for maximum of certain amount say 10 seconds of time for the element to be displayed as below:
(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return d.findElement(By.id("<name>")).isDisplayed();
}
});
I had a similar issue thanks @ford04 helped me out.
However, another error occurred.
NB. I am using ReactJS hooks
ndex.js:1 Warning: Cannot update during an existing state transition (such as within `render`). Render methods should be a pure function of props and state.
What causes the error?
import {useHistory} from 'react-router-dom'
const History = useHistory()
if (true) {
history.push('/new-route');
}
return (
<>
<render component />
</>
)
This could not work because despite you are redirecting to new page all state and props are being manipulated on the dom or simply rendering to the previous page did not stop.
What solution I found
import {Redirect} from 'react-router-dom'
if (true) {
return <redirect to="/new-route" />
}
return (
<>
<render component />
</>
)
Your class shoud look something like this:
class Something { int[] array; //global array, replace type of course void function1() { array = new int[10]; //let say you declare it here that will be 10 integers in size } void function2() { array[0] = 12; //assing value at index 0 to 12. } }
That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.
At the last line of app.js just put this function. This will override the default page-not-found error page:
app.use(function (req, res) {
res.status(404).render('error');
});
It will override all the requests that don't have a valid handler and render your own error page.

Use absolute path:
extension_dir="C:\full\path\here"
You can simply set the status code of the response to 200 like the following
public ActionResult SomeMethod(parameters...)
{
//others code here
...
Response.StatusCode = 200;
return YourObject;
}
As has been pointed out, this error is likely caused by a missing or incorrect intent-filter
.
I would just like to add that this error also shows up if you set android:exported="false"
on your launcher activity (in the manifest).

This happened to me when I did not refer to the master branch of the origin. So, you can try the following:
git pull origin master
This creates a reference to the master branch of the origin in the local repository. Then you can push the local repository to the origin.
git push -u origin master
Setting the underlying socket ReceiveTimeout
property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout
. You can read the docs for more information.
Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.
I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:
string SendCmd(string cmd, string ip, int port)
{
var client = new TcpClient(ip, port);
var data = Encoding.GetEncoding(1252).GetBytes(cmd);
var stm = client.GetStream();
stm.Write(data, 0, data.Length);
byte[] resp = new byte[2048];
var memStream = new MemoryStream();
var bytes = 0;
client.Client.ReceiveTimeout = 20;
do
{
try
{
bytes = stm.Read(resp, 0, resp.Length);
memStream.Write(resp, 0, bytes);
}
catch (IOException ex)
{
// if the ReceiveTimeout is reached an IOException will be raised...
// with an InnerException of type SocketException and ErrorCode 10060
var socketExept = ex.InnerException as SocketException;
if (socketExept == null || socketExept.ErrorCode != 10060)
// if it's not the "expected" exception, let's not hide the error
throw ex;
// if it is the receive timeout, then reading ended
bytes = 0;
}
} while (bytes > 0);
return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}
I think this is what your looking for:
var objs= (from c in List_Objects
orderby c.TypeID select c).GroupBy(g=>g.TypeID).Select(x=>x.FirstOrDefault());

In the interests of completeness there are a couple of other solutions which (in my opinion) are more orthodox than solutions relying on the SqlDependency (and SqlTableDependency) classes. SqlDependency was originally designed to make refreshing distributed webserver caches easier, and so was built to a different set of requirements than if it were designed as an event producer.
There are broadly four options, some of which have not been covered here already:
Change tracking
Change tracking is a lightweight notification mechanism in SQL server. Basically, a database-wide version number is incremented with every change to any data. The version number is then written to the change tracking tables with a bit mask including the names of the columns which were changed. Note, the actual change is not persisted. The notification only contains the information that a particular data entity has changed. Further, because the change table versioning is cumulative, change notifications on individual items are not preserved and are overwritten by newer notifications. This means that if an entity changes twice, change tracking will only know about the most recent change.
In order to capture these changes in c#, polling must be used. The change tracking tables can be polled and each change inspected to see if is of interest. If it is of interest, it is necessary to then go directly to the data to retrieve the current state.
Change Data Capture
Source: https://technet.microsoft.com/en-us/library/bb522489(v=sql.105).aspx
Change data capture (CDC) is more powerful but most costly than change tracking. Change data capture will track and notify changes based on monitoring the database log. Because of this CDC has access to the actual data which has been changed, and keeps a record of all individual changes.
Similarly to change tracking, in order to capture these changes in c#, polling must be used. However, in the case of CDC, the polled information will contain the change details, so it's not strictly necessary to go back to the data itself.
Triggers to queues
Source: https://code.msdn.microsoft.com/Service-Broker-Message-e81c4316
This technique depends on triggers on the tables from which notifications are required. Each change will fire a trigger, and the trigger will write this information to a service broker queue. The queue can then be connected to via C# using the Service Broker Message Processor (sample in the link above).
Unlike change tracking or CDC, triggers to queues do not rely on polling and thereby provides realtime eventing.
CLR
This is a technique I have seen used, but I would not recommend it. Any solution which relies on the CLR to communicate externally is a hack at best. The CLR was designed to make writing complex data processing code easier by leveraging C#. It was not designed to wire in external dependencies like messaging libraries. Furthermore, CLR bound operations can break in clustered environments in unpredictable ways.
This said, it is fairly straightforward to set up, as all you need to do is register the messaging assembly with CLR and then you can call away using triggers or SQL jobs.
In summary...
It has always been a source of amazement to me that Microsoft has steadfastly refused to address this problem space. Eventing from database to code should be a built-in feature of the database product. Considering that Oracle Advanced Queuing combined with the ODP.net MessageAvailable event provided reliable database eventing to C# more than 10 years ago, this is woeful from MS.
The upshot of this is that none of the solutions listed to this question are very nice. They all have technical drawbacks and have a significant setup cost. Microsoft if you're listening, please sort out this sorry state of affairs.
I was in the same situation and found this one,
I did the same thing that @Diode, the first answer, but i made the condition with a range of dates, i hope this example going to be useful for someone
e.g (the same code to example with array of dates)
var dateFrom = "02/06/2013";_x000D_
var dateTo = "02/09/2013";_x000D_
_x000D_
var d1 = dateFrom.split("/");_x000D_
var d2 = dateTo.split("/");_x000D_
_x000D_
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]); // -1 because months are from 0 to 11_x000D_
var to = new Date(d2[2], parseInt(d2[1])-1, d2[0]); _x000D_
_x000D_
_x000D_
_x000D_
var dates= ["02/06/2013", "02/07/2013", "02/08/2013", "02/09/2013", "02/07/2013", "02/10/2013", "02/011/2013"];_x000D_
_x000D_
dates.forEach(element => {_x000D_
let parts = element.split("/");_x000D_
let date= new Date(parts[2], parseInt(parts[1]) - 1, parts[0]);_x000D_
if (date >= from && date < to) {_x000D_
console.log('dates in range', date);_x000D_
}_x000D_
})
_x000D_
Try http://php.net/manual/en/curl.examples-basic.php :)
<?php
$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
$output = curl_exec($ch);
curl_close($ch);
fclose($fp);
?>
As the documentation says:
The basic idea behind the cURL functions is that you initialize a cURL session using the curl_init(), then you can set all your options for the transfer via the curl_setopt(), then you can execute the session with the curl_exec() and then you finish off your session using the curl_close().
I would rather create a function like TryParse or use T-SQL TRY-CATCH
block to get what you wanted.
ISNUMERIC doesn't always work as intended. The code given before will fail if you do:
SET @text = '$'
$ sign can be converted to money datatype, so ISNUMERIC()
returns true in that case. It will do the same for '-' (minus), ',' (comma) and '.' characters.

We use IEnumerable
and IQueryable
to manipulate the data that is retrieved from database. IQueryable
inherits from IEnumerable
, so IQueryable
does contain all the IEnumerable
features. The major difference between IQueryable
and IEnumerable
is that IQueryable
executes query with filters whereas IEnumerable
executes the query first and then it filters the data based on conditions.
Find more detailed differentiation below :
IEnumerable
IEnumerable
exists in the System.Collections
namespaceIEnumerable
execute a select query on the server side, load data in-memory on a client-side and then filter dataIEnumerable
is suitable for querying data from in-memory collections like List, ArrayIEnumerable
is beneficial for LINQ to Object and LINQ to XML queriesIQueryable
IQueryable
exists in the System.Linq
namespaceIQueryable
executes a 'select query' on server-side with all filtersIQueryable
is suitable for querying data from out-memory (like remote database, service) collectionsIQueryable
is beneficial for LINQ to SQL queriesSo IEnumerable
is generally used for dealing with in-memory collection, whereas, IQueryable
is generally used to manipulate collections.
This could be the possible solution
var str = 'RACK NO:Stock;PRODUCT TYPE:Stock Sale;PART N0:0035719061;INDEX NO:21A627 042;PART NAME:SPRING;';
var newstr = str.split(':')[1].split(';')[0]; // return value as 'Stock'
console.log('stringvalue',newstr)
Always check with your business domain expert. If that's you, look for an industry standard. If, for example, the domain in question is a natural person's family name (surname) then for a UK business I'd go to the UK Govtalk data standards catalogue for person information and discover that a family name will be between 1 and 35 characters.
There is no cross platform way that I know.
For Linux: readlink /proc/self/exe
Windows: GetModuleFileName
Using the C# language constructs, you cannot explicitly call the base function from outside the scope of A
or B
. If you really need to do that, then there is a flaw in your design - i.e. that function shouldn't be virtual to begin with, or part of the base function should be extracted to a separate non-virtual function.
You can from inside B.X however call A.X
class B : A
{
override void X() {
base.X();
Console.WriteLine("y");
}
}
But that's something else.
As Sasha Truf points out in this answer, you can do it through IL. You can probably also accomplish it through reflection, as mhand points out in the comments.
Another simplest way is to create a layout file containing the textview you want with textSize, textStyle, color etc preferred by you and then use it with the ArrayAdapter.
e.g. mytextview.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tv"
android:textColor="@color/font_content"
android:padding="5sp"
android:layout_width="fill_parent"
android:background="@drawable/rectgrad"
android:singleLine="true"
android:gravity="center"
android:layout_height="fill_parent"/>
and then use it with your ArrayAdapter as usual like
ListView lst = new ListView(context);
String[] arr = {"Item 1","Item 2"};
ArrayAdapter<String> ad = new ArrayAdapter<String>(context,R.layout.mytextview,arr);
lst.setAdapter(ad);
This way you won't need to create a custom adapter for it.
The cut command is designed for this exact situation. It will "cut" on any delimiter and then you can specify which chunks should be output.
For instance:
echo "foo bar <foo> bla 1 2 3.4" | cut -d " " -f 6-7
Will result in output of:
2 3.4
-d sets the delimiter
-f selects the range of 'fields' to output, in this case, it's the 6th through 7th chunks of the original string. You can also specify the range as a list, such as 6,7
.
Just ask it for the objectForKey:@"b"
. If it returns nil
, no object is set at that key.
if ([xyz objectForKey:@"b"]) {
NSLog(@"There's an object set for key @\"b\"!");
} else {
NSLog(@"No object set for key @\"b\"");
}
Edit: As to your edited second question, it's simply NSUInteger mCount = [xyz count];
. Both of these answers are documented well and easily found in the NSDictionary class reference ([1] [2]).
TCP keepalive socket option (SO_KEEPALIVE) would help in this scenario and close server socket in case of connection loss.
Also, as per the doc:
default cannot be specified via command line
https://guides.rubyonrails.org/active_record_migrations.html
So there is no ready-made rails generator. As specified by above answers, you have to fill manually your migration file with the change_column_default
method.
You could create your own generator: https://guides.rubyonrails.org/generators.html
To get every part of the URL except for the query:
var url = (location.origin).concat(location.pathname).concat(location.hash);
Note that this includes the hash as well, if there is one (I'm aware there's no hash in your example URL, but I included that aspect for completeness). To eliminate the hash, simply exclude .concat(location.hash)
.
It's better practice to use concat
to join Javascript strings together (rather than +
): in some situations it avoids problems such as type confusion.
I have been in this position, especially with new hardware. I suggest you write a little hex dump routine of your own. You will be able to see the data, and the addresses they are at, shown all together. It's good practice and a confidence builder.
When you run selenium WebDriver, the WebDriver opens a remote server in your computer's local host. Now, this server, called the Selenium Server, is used to interpret your code into actions to run or "drive" the instance of a real browser known as either chromebrowser, ie broser, ff browser, etc.
So, the Selenium Server can interact with different browser properties and hence it has many "capabilities".
Now what capabilities do you desire? Consider a scenario where you are validating if files have been downloaded properly in your app but, however, you do not have a desktop automation tool. In the case where you click the download link and a desktop pop up shows up to ask where to save and/or if you want to download. Your next route to bypass that would be to suppress that pop up. How? Desired Capabilities.
There are other such examples. In summary, Selenium Server can do a lot, use Desired Capabilities to tailor it to your need.
This worked for me,
CREATE TABLE newtable LIKE oldtable;
Replicates newtable with old table
INSERT newtable SELECT * FROM oldtable
;
Copies all the row data to new table.
Thank you
The default behaviour of divs is to take the full width available in their parent container.
This is the same as if you'd give the inner divs a width of 100%.
By floating the divs, they ignore their default and size their width to fit the content. Everything behind it (in the HTML), is placed under the div (on the rendered page).
This is the reason that they align theirselves next to each other.
The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.
Source: https://developer.mozilla.org/en-US/docs/Web/CSS/float
Get rid of the float, and the divs will be aligned under each other.
If this does not happen, you'll have some other css on divs or children of wrapper defining a floating behaviour or an inline display.
If you want to keep the float, for whatever reason, you can use clear
on the 2nd div to reset the floating properties of elements before that element.
clear
has 5 valid values: none | left | right | both | inherit
. Clearing no floats (used to override inherited properties), left or right floats or both floats. Inherit means it'll inherit the behaviour of the parent element
Also, because of the default behaviour, you don't need to set the width and height on auto.
You only need this is you want to set a hardcoded height/width. E.g. 80% / 800px / 500em / ...
<div id="wrapper">
<div id="inner1"></div>
<div id="inner2"></div>
</div>
CSS is
#wrapper{
margin-left:auto;
margin-right:auto;
height:auto; // this is not needed, as parent container, this div will size automaticly
width:auto; // this is not needed, as parent container, this div will size automaticly
}
/*
You can get rid of the inner divs in the css, unless you want to style them.
If you want to style them identicly, you can use concatenation
*/
#inner1, #inner2 {
border: 1px solid black;
}
You have to go through the collection from the last item to the first. this code is in vb
for i as integer= list.items.count-1 to 0 step -1
....
list.items.removeat(i)
next
It works better
CREATE TABLE [dbo].[T_Status](
[Status] [nvarchar](20) NULL
) ON [PRIMARY]
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'Active')
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'notActive')
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'Active')
GO
DECLARE @GetStatus nvarchar(20) = null
--DECLARE @GetStatus nvarchar(20) = 'Active'
SELECT [Status]
FROM [T_Status]
WHERE [Status] = CASE WHEN (isnull(@GetStatus, '')='') THEN [Status]
ELSE @GetStatus END
I believe Spring Boot supports loading properties maps out of the box with @ConfigurationProperties annotation.
According that docs you can load properties:
my.servers[0]=dev.bar.com
my.servers[1]=foo.bar.com
into bean like this:
@ConfigurationProperties(prefix="my")
public class Config {
private List<String> servers = new ArrayList<String>();
public List<String> getServers() {
return this.servers;
}
}
I used @ConfigurationProperties feature before, but without loading into map. You need to use @EnableConfigurationProperties annotation to enable this feature.
Cool stuff about this feature is that you can validate your properties.
two of the best options are
$(this).parent("div:first")
$(this).parent().closest('div')
and of course you can find the class attr by
$(this).parent("div:first").attr("class")
$(this).parent().closest('div').attr("class")
This is how to install a normal MSI file silently:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"
Quick explanation:
/L*V "C:\Temp\msilog.log"= verbose logging at indicated path
/QN = run completely silently
/i = run install sequence
The msiexec.exe command line is extensive with support for a variety of options. Here is another overview of the same command line interface. Here is an annotated versions (was broken, resurrected via way back machine).
It is also possible to make a batch file a lot shorter with constructs such as for loops as illustrated here for Windows Updates.
If there are check boxes that must be checked during the setup, you must find the appropriate PUBLIC PROPERTIES attached to the check box and set it at the command line like this:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log" STARTAPP=1 SHOWHELP=Yes
These properties are different in each MSI. You can find them via the verbose log file or by opening the MSI in Orca, or another appropriate tool. You must look either in the dialog control section or in the Property table for what the property name is. Try running the setup and create a verbose log file first and then search the log for messages ala "Setting property..." and then see what the property name is there. Then add this property with the value from the log file to the command line.
Also have a look at how to use transforms to customize the MSI beyond setting command line parameters: How to make better use of MSI files
Update: For a more correct answer see Tim Down's answer.
Internet Explorer and, for example, Mozilla-based browsers expose different objects for XML parsing, so it's wise to use a JavaScript framework like jQuery to handle the cross-browsers differences.
A really basic example is:
var xml = "<music><album>Beethoven</album></music>";
var result = $(xml).find("album").text();
Note: As pointed out in comments; jQuery does not really do any XML parsing whatsoever, it relies on the DOM innerHTML method and will parse it like it would any HTML so be careful when using HTML element names in your XML. But I think it works fairly good for simple XML 'parsing', but it's probably not suggested for intensive or 'dynamic' XML parsing where you do not upfront what XML will come down and this tests if everything parses as expected.
Or you could try:
Check this out:
XAML:
<DataGrid Name="DataGrid1">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Click="ChangeText">Show/Hide</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
Method:
private void ChangeText(object sender, RoutedEventArgs e)
{
DemoModel model = (sender as Button).DataContext as DemoModel;
model.DynamicText = (new Random().Next(0, 100).ToString());
}
Class:
class DemoModel : INotifyPropertyChanged
{
protected String _text;
public String Text
{
get { return _text; }
set { _text = value; RaisePropertyChanged("Text"); }
}
protected String _dynamicText;
public String DynamicText
{
get { return _dynamicText; }
set { _dynamicText = value; RaisePropertyChanged("DynamicText"); }
}
public event PropertyChangedEventHandler PropertyChanged;
public void RaisePropertyChanged(String propertyName)
{
PropertyChangedEventHandler temp = PropertyChanged;
if (temp != null)
{
temp(this, new PropertyChangedEventArgs(propertyName));
}
}
}
Initialization Code:
ObservableCollection<DemoModel> models = new ObservableCollection<DemoModel>();
models.Add(new DemoModel() { Text = "Some Text #1." });
models.Add(new DemoModel() { Text = "Some Text #2." });
models.Add(new DemoModel() { Text = "Some Text #3." });
models.Add(new DemoModel() { Text = "Some Text #4." });
models.Add(new DemoModel() { Text = "Some Text #5." });
DataGrid1.ItemsSource = models;
If you are using getActivity() then you have to make sure that the calling activity is added already. If activity has not been added in such case so you may get null when you call getActivity()
in such cases getContext() is safe
then the code for starting the activity will be slightly changed like,
Intent intent = new Intent(getContext(), mFragmentFavorite.class);
startActivity(intent);
Activity, Service and Application extends ContextWrapper class so you can use this or getContext() or getApplicationContext() in the place of first argument.
If you need some logical control over character removal, use this
String string = "sdsdsd";
char[] arr = string.toCharArray();
// Run loop or whatever you need
String ss = new String(arr);
If you don't need any such control, you can use what Oscar orBhesh mentioned. They are spot on.
Try this:
var mydtn = DateTime.Today;
var myDt = mydtn.Date;return myDt.ToString("d", CultureInfo.GetCultureInfo("en-US"));
The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).
So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.
However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size
in pixels in relation to device screen sizes.
The suggested font-sizes for screen resolutions suggested from that article are as follows:
@media (min-width: 858px) {
html {
font-size: 12px;
}
}
@media (min-width: 780px) {
html {
font-size: 11px;
}
}
@media (min-width: 702px) {
html {
font-size: 10px;
}
}
@media (min-width: 724px) {
html {
font-size: 9px;
}
}
@media (max-width: 623px) {
html {
font-size: 8px;
}
}
I was having same issue.
String[] arr= new String[] { "A", "B", "C" };
Object obj = arr;
And then passed the obj as varargs argument. It worked.
I have added the following on my excel sheet
=VLOOKUP(B2,Res_partner!$A$2:$C$21208,1,FALSE)
Still doesn't seem to work. I get an #N/A
BUT
=VLOOKUP(B2,Res_partner!$C$2:$C$21208,1,FALSE)
Works
You can use the react-moment package
-> https://www.npmjs.com/package/react-moment
Put in your file the next line:
import moment from "moment";
date_create: moment().format("DD-MM-YYYY hh:mm:ss")
When there is no records returned from Database for a particular condition and When I tried to access the rs.getString(1); I got this error "exhausted resultset".
Before the issue, my code was:
rs.next();
sNr= rs.getString(1);
After the fix:
while (rs.next()) {
sNr = rs.getString(1);
}
var str = "I learned to play the Ukulele in Lebanon."
var regex = /le/gi, result, indices = [];
while ( (result = regex.exec(str)) ) {
indices.push(result.index);
}
UPDATE
I failed to spot in the original question that the search string needs to be a variable. I've written another version to deal with this case that uses indexOf
, so you're back to where you started. As pointed out by Wrikken in the comments, to do this for the general case with regular expressions you would need to escape special regex characters, at which point I think the regex solution becomes more of a headache than it's worth.
function getIndicesOf(searchStr, str, caseSensitive) {_x000D_
var searchStrLen = searchStr.length;_x000D_

A pointer to member function is different from a pointer to function. In order to use a member function through a pointer you need a pointer to it (obviously ) and an object to apply it to. So the appropriate version of function1
would be
void function1(void (aClass::*function)(int, int), aClass& a) {
(a.*function)(1, 1);
}
and to call it:
aClass a; // note: no parentheses; with parentheses it's a function declaration
function1(&aClass::test, a);
You may be tempted to use memcmp(&a, &b, sizeof(struct foo))
, but it may not work in all situations. The compiler may add alignment buffer space to a structure, and the values found at memory locations lying in the buffer space are not guaranteed to be any particular value.
But, if you use calloc
or memset
the full size of the structures before using them, you can do a shallow comparison with memcmp
(if your structure contains pointers, it will match only if the address the pointers are pointing to are the same).
You can use
shouldShowRequestPermissionRationale()
inside
onRequestPermissionsResult()
See the example below:
Check if it has permission when the user clicks the button:
@Override
public void onClick(View v) {
if (v.getId() == R.id.appCompatBtn_changeProfileCoverPhoto) {
if (Build.VERSION.SDK_INT < 23) { // API < 23 don't need to ask permission
navigateTo(MainActivity.class); // Navigate to activity to change photos
} else {
if (ContextCompat.checkSelfPermission(SettingsActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
// Permission is not granted yet. Ask for permission...
requestWriteExternalPermission();
} else {
// Permission is already granted, good to go :)
navigateTo(MainActivity.class);
}
}
}
}
When the user answer the permission dialog box we will go to onRequestPermissionResult:
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == WRITE_EXTERNAL_PERMISSION_REQUEST_CODE) {
// Case 1. Permission is granted.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (ContextCompat.checkSelfPermission(SettingsActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
// Before navigating, I still check one more time the permission for good practice.
navigateTo(MainActivity.class);
}
} else { // Case 2. Permission was refused
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
// Case 2.1. shouldShowRequest... returns true because the
// permission was denied before. If it is the first time the app is running we will
// end up in this part of the code. Because he need to deny at least once to get
// to onRequestPermissionsResult.
Snackbar snackbar = Snackbar.make(findViewById(R.id.relLayout_container), R.string.you_must_verify_permissions_to_send_media, Snackbar.LENGTH_LONG);
snackbar.setAction("VERIFY", new View.OnClickListener() {
@Override
public void onClick(View v) {
ActivityCompat.requestPermissions(SettingsActivity.this
, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}
, WRITE_EXTERNAL_PERMISSION_REQUEST_CODE);
}
});
snackbar.show();
} else {
// Case 2.2. Permission was already denied and the user checked "Never ask again".
// Navigate user to settings if he choose to allow this time.
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.instructions_to_turn_on_storage_permission)
.setPositiveButton(getString(R.string.settings), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent settingsIntent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", getPackageName(), null);
settingsIntent.setData(uri);
startActivityForResult(settingsIntent, 7);
}
})
.setNegativeButton(getString(R.string.not_now), null);
Dialog dialog = builder.create();
dialog.show();
}
}
}
}
SELECT COUNT(*)
FROM table_emp
WHERE YEAR(ARR_DATE) = '2012'
GROUP BY MONTH(ARR_DATE)
Currently there is another approach possible if classes are used in code.
With support of class fields it's possible to make it next way:
class someView {
onSomeInputKeyUp = (event) => {
console.log(this); // this refers to correct value
// ....
someInitMethod() {
//...
someInput.addEventListener('input', this.onSomeInputKeyUp)
For sure under the hood it's all old good arrow function that bind context but in this form it looks much more clear that explicit binding.
Since it's Stage 3 Proposal you will need babel and appropriate babel plugin to process it as for now(08/2018).
Use the following code fragment to hide the form on button click.
document.getElementById("your form id").style.display="none";
And the following code to display it:
document.getElementById("your form id").style.display="block";
Or you can use the same function for both purposes:
function asd(a)
{
if(a==1)
document.getElementById("asd").style.display="none";
else
document.getElementById("asd").style.display="block";
}
And the HTML:
<form id="asd">form </form>
<button onclick="asd(1)">Hide</button>
<button onclick="asd(2)">Show</button>
Did you try [textView sizeThatFits:textView.bounds]
?
Edit: sizeThatFits returns the size but does not actually resize the component. I'm not sure if that's what you want, or if [textView sizeToFit]
is more what you were looking for. In either case, I do not know if it will perfectly fit the content like you want, but it's the first thing to try.
In ~/.subversion/auth/svn.simple/
you should find a file with a long hexadecimal name. The password is in there in plaintext.
If there is more than one file you'll need to find that one that references the server you need the password for.
You can also receive a 406 response when invalid cookies are stored or referenced in the browser - for example, when running a Rails server in Dev mode locally.
If you happened to run two different projects on the same port, the browser might reference a cookie from a different localhost session.
This has happened to me...tripped me up for a minute. Looking in browser > Developer Mode > Network showed it.
Another useful variant is pipe to tr
:
echo "${my_array[@]}" | tr ' ' '\n'
This looks simple and compact
I got this solution and it is working for me
if (myNewDT.MyDateTime == null)
{
myNewDT.MyDateTime = DateTime.Now();
}
I've had this error on and off for around two years in a several XLSM files (which is most annoying as when it occurs there is nothing wrong with the file! - I suspect orphaned Excel processes are part of the problem)
The most efficient solution I had found has been to use Python with oletools
https://github.com/decalage2/oletools/wiki/Install
and extract the VBA code all the modules and save in a text file.
Then I simply rename the file to zip file (backup just in case!), open up this zip file and delete the xl/vbaProject.bin file. Rename back to XLSX and should be good to go.
Copy in the saved VBA code (which will need cleaning of line breaks, comments and other stuff. Will also need to add in missing libraries.
This has saved me when other methods haven't.
YMMV.
the answer is when you load the file, you need apply the "close" method, in any line of code, works to me
I had a similar issue recently. I was trying to access an https REST endpoint which had a self signed certificate. I was getting net::ERR_INSECURE_RESPONSE
in the Google Chrome console. Did a bit of searching on the web to find this solution that worked for me:
<url>
and you should see the response (if there is one)Topshelf is an OSS project which was started after this question was answered and it makes Windows service much, MUCH easier.I highly recommend looking into it.
To get the value equivalent to your C cast, just bitwise and with the appropriate mask. e.g. if unsigned long
is 32 bit:
>>> i = -6884376
>>> i & 0xffffffff
4288082920
or if it is 64 bit:
>>> i & 0xffffffffffffffff
18446744073702667240
Do be aware though that although that gives you the value you would have in C, it is still a signed value, so any subsequent calculations may give a negative result and you'll have to continue to apply the mask to simulate a 32 or 64 bit calculation.
This works because although Python looks like it stores all numbers as sign and magnitude, the bitwise operations are defined as working on two's complement values. C stores integers in twos complement but with a fixed number of bits. Python bitwise operators act on twos complement values but as though they had an infinite number of bits: for positive numbers they extend leftwards to infinity with zeros, but negative numbers extend left with ones. The &
operator will change that leftward string of ones into zeros and leave you with just the bits that would have fit into the C value.
Displaying the values in hex may make this clearer (and I rewrote to string of f's as an expression to show we are interested in either 32 or 64 bits):
>>> hex(i)
'-0x690c18'
>>> hex (i & ((1 << 32) - 1))
'0xff96f3e8'
>>> hex (i & ((1 << 64) - 1)
'0xffffffffff96f3e8L'
For a 32 bit value in C, positive numbers go up to 2147483647 (0x7fffffff), and negative numbers have the top bit set going from -1 (0xffffffff) down to -2147483648 (0x80000000). For values that fit entirely in the mask, we can reverse the process in Python by using a smaller mask to remove the sign bit and then subtracting the sign bit:
>>> u = i & ((1 << 32) - 1)
>>> (u & ((1 << 31) - 1)) - (u & (1 << 31))
-6884376
Or for the 64 bit version:
>>> u = 18446744073702667240
>>> (u & ((1 << 63) - 1)) - (u & (1 << 63))
-6884376
This inverse process will leave the value unchanged if the sign bit is 0, but obviously it isn't a true inverse because if you started with a value that wouldn't fit within the mask size then those bits are gone.
You can just compare the boolean array. For example
X = [True, False, True]
then
Y = X == False
would give you
Y = [False, True, False]
Infinity, NaN and subnormals
These are important caveats that no other answer has mentioned so far.
First read this introduction to IEEE 754 and subnormal numbers: What is a subnormal floating point number?
Then, for single precision floats (32-bit):
IEEE 754 says that if the exponent is all ones (0xFF == 255
), then it represents either NaN or Infinity.
This is why the largest non-infinite number has exponent 0xFE == 254
and not 0xFF
.
Then with the bias, it becomes:
254 - 127 == 127
FLT_MIN
is the smallest normal number. But there are smaller subnormal ones! Those take up the -127
exponent slot.
All asserts of the following program pass on Ubuntu 18.04 amd64:
#include <assert.h>

#include <stdio.h>
float float_from_bytes(

uint32_t fraction
) {
uint32_t bytes;
bytes = 0;
bytes |= sign;
bytes <<= 8;
bytes |= exponent;
bytes <<= 23;
bytes |= fraction;
return *(float*)&bytes;
}
int main(void) {
/* All 1 exponent and non-0 fraction means NaN.
* There are of course many possible representations,
* and some have special semantics such as signalling vs not.
*/
assert(isnan(float_from_bytes(0, 0xFF, 1)));
assert(isnan(NAN));
printf("nan = %e\n", NAN);
/* All 1 exponent and 0 fraction means infinity. */
assert(INFINITY == float_from_bytes(0, 0xFF, 0));
assert(isinf(INFINITY));
printf("infinity = %e\n", INFINITY);
/* ANSI C defines FLT_MAX as the largest non-infinite number. */
assert(FLT_MAX == 0x1.FFFFFEp127f);
/* Not 0xFF because that is infinite. */
assert(FLT_MAX == float_from_bytes(0, 0xFE, 0x7FFFFF));
assert(!isinf(FLT_MAX));
assert(FLT_MAX < INFINITY);
printf("largest non infinite = %e\n", FLT_MAX);
/* ANSI C defines FLT_MIN as the smallest non-subnormal number. */
assert(FLT_MIN == 0x1.0p-126f);
assert(FLT_MIN == float_from_bytes(0, 1, 0));
assert(isnormal(FLT_MIN));
printf("smallest normal = %e\n", FLT_MIN);
/* The smallest non-zero subnormal number. */
float smallest_subnormal = float_from_bytes(0, 0, 1);
assert(smallest_subnormal == 0x0.000002p-126f);
assert(0.0f < smallest_subnormal);
assert(!isnormal(smallest_subnormal));
printf("smallest subnormal = %e\n", smallest_subnormal);
return EXIT_SUCCESS;
}
Compile and run with:
gcc -ggdb3 -O0 -std=c11 -Wall -Wextra -Wpedantic -Werror -o subnormal.out subnormal.c
./subnormal.out
Output:
nan = nan
infinity = inf
largest non infinite = 3.402823e+38
smallest normal = 1.175494e-38
smallest subnormal = 1.401298e-45

You can use VARRAY for a fixed-size array:
declare
type array_t is varray(3) of varchar2(10);
array array_t := array_t('Matt', 'Joanne', 'Robert');
begin
for i in 1..array.count loop
dbms_output.put_line(array(i));
end loop;
end;
Or TABLE for an unbounded array:
...
type array_t is table of varchar2(10);
...
The word "table" here has nothing to do with database tables, confusingly. Both methods create in-memory arrays.
With either of these you need to both initialise and extend the collection before adding elements:
declare
type array_t is varray(3) of varchar2(10);
array array_t := array_t(); -- Initialise it
begin
for i in 1..3 loop
array.extend(); -- Extend it
array(i) := 'x';
end loop;
end;
The first index is 1 not 0.
I am fairly sure that Linq can do this.... but MyList does not have a select method on it (which is what I would have used).
Yes, LINQ can do this. It's simply:
MyList.Select(x => x.Name).ToArray();
Most likely the issue is that you either don't have a reference to System.Core
, or you are missing an using
directive for System.Linq
.
In SL5 I found this to work:
<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat=dd-MMMM-yy hh:mm}">
<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat='Justification Date: \{0:dd-MMMM-yy hh:mm\}'}">
For the sake of completeness.
Using Java8
people.sort(Comparator.comparingInt(People::getId));
if you want in descending order
people.sort(Comparator.comparingInt(People::getId).reversed());
I solved the problem by using this
tr td input[type=text] {
width: 100%;
box-sizing: border-box;
-webkit-box-sizing:border-box;
-moz-box-sizing: border-box;
background:transparent !important;
border: 0px;
}
props.put("mail.smtp.starttls.enable", "true");
solved my problem ;)
My problem was :

This works for me perfectly!
Try with these following examples in this article : http://phpswitch.com/
Possible Switch Cases :
(i). A simple switch statement
The switch statement is wondrous and magic. It's a piece of the language that allows you to select between different options for a value, and run different pieces of code depending on which value is set.
Each possible option is given by a case in the switch statement.
Example :
switch($bar)
{
case 4:
echo "This is not the number you're looking for.\n";
$foo = 92;
}
(ii). Delimiting code blocks
The major caveat of switch is that each case will run on into the next one, unless you stop it with break. If the simple case above is extended to cover case 5:
Example :
case 4:
echo "This is not the number you're looking for.\n";
$foo = 92;
break;
case 5:
echo "A copy of Ringworld is on its way to you!\n";
$foo = 34;
break;
(iii). Using fallthrough for multiple cases
Because switch will keep running code until it finds a break, it's easy enough to take the concept of fallthrough and run the same code for more than one case:
Example :
case 2:
case 3:
case 4:
echo "This is not the number you're looking for.\n";
$foo = 92;
break;
case 5:
echo "A copy of Ringworld is on its way to you!\n";
$foo = 34;
break;
(iv). Advanced switching: Condition cases
PHP's switch doesn't just allow you to switch on the value of a particular variable: you can use any expression as one of the cases, as long as it gives a value for the case to use. As an example, here's a simple validator written using switch:
Example :
switch(true)
{
case (strlen($foo) > 30):
$error = "The value provided is too long.";
$valid = false;
break;
case (!preg_match('/^[A-Z0-9]+$/i', $foo)):
$error = "The value must be alphanumeric.";
$valid = false;
break;
default:
$valid = true;
break;
}
i think this may help you to resolve your problem.
To Summarize all of these, just keep one thing in your mind that everything except footer should have min-height: 100%
or little less.
