As android latest update doesn't support 'compile' keyword use 'implementation' in place inside your module build.gradle file.
And check thoroughly in build.gradle for dependancy with + sign like this.
implementation 'com.android.support:support-v4:28.+'
If there are any dependencies like this, just update them with a specific version. After that:
I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:
multiDexEnabled true
And it worked!
Example
android {
compileSdkVersion 27
buildToolsVersion '27.0.1'
defaultConfig {
applicationId "com.xx.xxx"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
multiDexEnabled true //Add this
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
And clean the project.
For me, adding
multiDexEnabled true
and
packagingOptions {
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
exclude 'META-INF/notice'
exclude 'META-INF/notice.txt'
exclude 'META-INF/license'
exclude 'META-INF/license.txt'
}
into the app level Build.gradle file solved the issue
In my case, Unfortunately, neither Michel's nor Suragch's solutions worked for me.
So I solved this issue by doing the following:
In gradle:3.0 the compile configuration is now deprecated and should be replaced by implementation or api. For more information you can read here You can read the official docs at Gradle Build Tool
The compile configuration still exists but should not be used as it will not offer the guarantees that the api and implementation configurations provide.
it's better to use implementation or api rather compile
just replace compile with implementation, debugCompile with debugImplementation, testCompile with testImplementation and androidtestcompile with androidTestImplementation
For example: Instead of this
compile 'com.android.support:appcompat-v7:26.0.2'
compile 'com.android.support:support-v4:26.1.0'
compile 'com.github.bumptech.glide:glide:4.0.0'
use like this
implementation 'com.android.support:appcompat-v7:26.0.2'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.github.bumptech.glide:glide:4.0.0'
After that
Hope it will helps !
In my case it was enough to exclude only path 'META-INF/DEPENDENCIES' on yourProject/app/build.gradle
inside android{}
. Here it is
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
}
And then do Clean Project and Rebuild Project.
delete intermediates folder from app\build\intermediates. then rebuild the project. it will work
Please Add this into your gradle file
android {
...
defaultConfig {
...
multiDexEnabled true
}
}
AND also add the below dependency in your gradle
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
OR another option would be: In your manifest file add the MultiDexApplication package from the multidex support library in the application tag.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.multidex.myapplication">
<application
...
android:name="android.support.multidex.MultiDexApplication">
...
</application>
</manifest>
For me Upgrading Gradle works.Look for update at Android Website then add it in your build.gradle (Project) like this
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0-alpha4'
....
}
then sync project with gradle file plus it might be happened sometimes because of java.exe (in my case) just force kill java.exe from task manager in windows then re run program
If you are applying any plugins. Then, in your module Gradle file (usually the app/build.gradle
),make sure you add the apply plugin
line at the bottom of the file to enable the Gradle plugin.
e.g.
I got this problem when I updated the Gradle plugin from version 1.2.3 to 1.5.0 as Android Studio suggested. In its web page, 1.5.0 appears to be a beta version.
Honestly, I don't know what advantages the version 1.5.0 has, but I'd rather wait until there's a stable version.
Of course, going back to 1.2.3 solved the issue.
For me the issue was caused by com.google.android.exoplayer
conflicting with com.facebook.android:audience-network-sdk
.
I fixed the problem by excluding the exoplayer
library from the audience-network-sdk
:
compile ('com.facebook.android:audience-network-sdk:4.24.0') {
exclude group: 'com.google.android.exoplayer'
}
It happened to me because of Eclipse memory leak. I had to restart my computer.
Same here with
dependencies {
compile 'org.apache.oltu.oauth2:org.apache.oltu.oauth2.client:1.0.0'
}
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
}
I lost like 2 days for that weird error... Why is this still happening in gradle 1.0.0 ? That is very disturbing for newbies... Anyway, thanks for that info i thought it was on my code :)
Go to xampp/php/php.ini
Find this line:
max_execution_time=30
And change its value to any number you want. Restart Apache.
Today NodeJS supports new async/await
syntax. This is an easy syntax and makes the life much easier
async function process(promises) { // must be an async function
let x = await Promise.all(promises); // now x will be an array
x = x.map( tmp => tmp * 10); // proccessing the data.
}
const promises = [
new Promise(resolve => setTimeout(resolve, 0, 1)),
new Promise(resolve => setTimeout(resolve, 0, 2))
];
process(promises)

I use quantiles to do bins uniform and fitted to sample:
bins=df['Generosity'].quantile([0,.05,0.1,0.15,0.20,0.25,0.3,0.35,0.40,0.45,0.5,0.55,0.6,0.65,0.70,0.75,0.80,0.85,0.90,0.95,1]).to_list()

To change your application to a different built-in theme, just add this line under application tag in your app's manifest.xml
file.
Example:
<application
android:theme="@android:style/Theme.Holo"/>
<application
android:theme="@android:style/Theme.Holo.Light"/>
<application
android:theme="@android:style/Theme.Black"/>
<application
android:theme="@android:style/Theme.DeviceDefault"/>
If you set style to DeviceDefault it will require min SDK version 14, but if you won't add a style, it will set to the device default anyway.
<uses-sdk
android:minSdkVersion="14"/>
you can put div tags inside a td tag, but not directly inside a table or tr tag. examples:
this works:
<table>_x000D_
<tr>_x000D_
<td> _x000D_
<div>This will work.</div> _x000D_
</td>_x000D_
</tr>_x000D_
<table>
_x000D_
this does not work:
<table>_x000D_
<tr>_x000D_
<div> this does not work. </div> _x000D_
</tr>_x000D_
</table>
_x000D_
nor does this work:
<table>_x000D_
<div> this does not work. </div>_x000D_
</table>
_x000D_
/\d+\.?\d*/
One or more digits (\d+
), optional period (\.?
), zero or more digits (\d*
).
Depending on your usage or regex engine you may need to add start/end line anchors:
/^\d+\.?\d*$/
There's another reason unserialize()
failed because you improperly put serialized data into the database see Official Explanation here. Since serialize()
returns binary data and php variables don't care encoding methods, so that putting it into TEXT, VARCHAR() will cause this error.
Solution: store serialized data into BLOB in your table.
Escape it: someString.replace(/\//g, "-");
Hammer.js all the way! It handles "transforms" (pinches). http://eightmedia.github.com/hammer.js/
But if you wish to implement it youself, i think that Jeffrey's answer is pretty solid.
you can use list to define it.
objs = list()
for i in range(10):
objs.append(MyClass())
string[] tokens = str.Split(new[] { "is Marco and" }, StringSplitOptions.None);
If you have a single character delimiter (like for instance ,
), you can reduce that to (note the single quotes):
string[] tokens = str.Split(',');
So I have been lurking on stack for so many years. This is actually my first time posting on here.
Anyhow, this might seem insane but I came across this post while struggling with the same issue and came up with a dirty solution. I know there are more elegant ways to perhaps set this as a property value but:
if you look at lines 12880-12883 in tcpdf.php :
$fx = ((($w - $this->getAbsFontMeasure($tmpfont['cw'][`110`])) / 2) * $this->k);
$fy = (($w - ((($tmpfont['desc']['Ascent'] - $tmpfont['desc']['Descent']) * $this->FontSizePt / 1000) / $this->k)) * $this->k);
$popt['ap']['n'][$onvalue] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`110`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);
$popt['ap']['n']['Off'] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`111`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);
and lines 13135-13138 :
$fx = ((($w - $this->getAbsFontMeasure($tmpfont['cw'][`108`])) / 2) * $this->k);
$fy = (($w - ((($tmpfont['desc']['Ascent'] - $tmpfont['desc']['Descent']) * $this->FontSizePt / 1000) / $this->k)) * $this->k);
$popt['ap']['n']['Yes'] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`108`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);
$popt['ap']['n']['Off'] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`109`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);
Those widgets are rendered from the zapfdingbats font set... just swap the character codes and voila... checks are radios and/or vice versa. This also opens up ideas to make a custom font set to use here and add some nice styling to your form elements.
Anyhow, just figured I would offer my two cents ... it worked awesome for me.
Or you can just make an ICollection extension like this:
public static ICollection<T> AddRange<T>(this ICollection<T> @this, IEnumerable<T> items)
{
foreach(var item in items)
{
@this.Add(item);
}
return @this;
}
Using it would be just like using it on a list:
collectionA.AddRange(IEnumerable<object> items);
Here is one way of doing this with List< KeyValuePair< string, string > >
public class ListWithDuplicates : List<KeyValuePair<string, string>>
{
public void Add(string key, string value)
{
var element = new KeyValuePair<string, string>(key, value);
this.Add(element);
}
}
var list = new ListWithDuplicates();
list.Add("k1", "v1");
list.Add("k1", "v2");
list.Add("k1", "v3");
foreach(var item in list)
{
string x = string.format("{0}={1}, ", item.Key, item.Value);
}
Outputs k1=v1, k1=v2, k1=v3
2020 edit
Use URLSearchParams, as this job no longer requires any kind of custom code. Browsers can do this for you with a single constructor:
const str = "1111342=Adam%20Franco&348572=Bob%20Jones";
const data = new URLSearchParams(str);
for (pair of data) console.log(pair)
yields
Array [ "1111342", "Adam Franco" ]
Array [ "348572", "Bob Jones" ]
So there is no reason to use regex for this anymore.
Original answer
If you don't want to rely on the "blind matching" that comes with running exec
style matching, JavaScript does come with match-all functionality built in, but it's part of the replace
function call, when using a "what to do with the capture groups" handling function:
var data = {};
var getKeyValue = function(fullPattern, group1, group2, group3) {
data[group2] = group3;
};
mystring.replace(/(?:&|&)?([^=]+)=([^&]+)/g, getKeyValue);
done.
Instead of using the capture group handling function to actually return replacement strings (for replace handling, the first arg is the full pattern match, and subsequent args are individual capture groups) we simply take the groups 2 and 3 captures, and cache that pair.
So, rather than writing complicated parsing functions, remember that the "matchAll" function in JavaScript is simply "replace" with a replacement handler function, and much pattern matching efficiency can be had.
PHP has Heredoc and Nowdoc strings, which are the best way to handle multiline strings in PHP.
http://php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc
$str = <<<EOD
Example of string
spanning multiple lines
using heredoc syntax.
$var is replaced automatically.
EOD;
A Nowdoc is like a Heredoc, but it doesn't replace variables.
$str = <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
$var is NOT replaced in a nowdoc.
EOD;
Beware that the end token EOD
must not be indented at all, or PHP won't acknowledge it. Also, you don't have to use "EOD
"; it can be any string you want.
Here's a nice implementation using the Thread class: http://g-off.net/software/a-python-repeatable-threadingtimer-class
the code below is a little more quick and dirty:
from threading import Timer
from time import sleep
def hello():
print "hello, world"
t = Timer(3,hello)
t.start()
t = Timer(3, hello)
t.start() # after 3 seconds, "hello, world" will be printed
# timer will wake up ever 3 seconds, while we do something else
while True:
print "do something else"
sleep(10)
First you have to create a migration, you can use the migrate:make command on the laravel artisan CLI.Old laravel version like laravel 4 you may use this command for Laravel 4:
php artisan migrate:make add_paid_to_users
And for laravel 5 version
for Laravel 5+:
php artisan make:migration add_paid_to_users_table --table=users
Then you need to use the Schema::table() . And you have to add the column:
public function up()
{
Schema::table('users', function($table) {
$table->integer('paid');
});
}
further you can check this
Try following code that worked fine for me
global $current_user;
get_currentuserinfo();
Then, use following code to check whether user has logged in or not.
if ($current_user->ID == '') {
//show nothing to user
}
else {
//write code to show menu here
}
Better way to do this use custom dialog and customize according your needs here is custom dialog example.....
public class CustomDialogUI {
Dialog dialog;
Vibrator vib;
RelativeLayout rl;
@SuppressWarnings("static-access")
public void dialog(final Context context, String title, String message,
final Runnable task) {
dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom);
dialog.setCancelable(false);
TextView m = (TextView) dialog.findViewById(R.id.message);
TextView t = (TextView) dialog.findViewById(R.id.title);
final Button n = (Button) dialog.findViewById(R.id.button2);
final Button p = (Button) dialog.findViewById(R.id.next_button);
rl = (RelativeLayout) dialog.findViewById(R.id.rlmain);
t.setText(bold(title));
m.setText(message);
dialog.show();
n.setText(bold("Close"));
p.setText(bold("Ok"));
// color(context,rl);
vib = (Vibrator) context.getSystemService(context.VIBRATOR_SERVICE);
n.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
vib.vibrate(15);
dialog.dismiss();
}
});
p.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
vib.vibrate(20);
dialog.dismiss();
task.run();
}
});
}
//customize text style bold italic....
public SpannableString bold(String s) {
SpannableString spanString = new SpannableString(s);
spanString.setSpan(new StyleSpan(Typeface.BOLD), 0,
spanString.length(), 0);
spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
// spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0,
// spanString.length(), 0);
return spanString;
}
}

I have alias push="git push origin HEAD"

I know I'm pushing to the current branch I'm on.
The keyCode
is deprecated you can use key
property in the KeyboardEvent
<textarea (keydown)=onKeydownEvent($event)></textarea>
Typescript:
onKeydownEvent($event: KeyboardEvent){
// you can use the following for checkig enter key pressed or not
if ($event.key === 'Enter') {
console.log($event.key); // Enter
}
if ($event.key === 'Enter' && event.shiftKey) {
//This is 'Shift+Enter'
}

One easy way to set a build as unstable, is in your "execute shell" block, run exit 13
When you define a server in server view, then it will create you a server runtime library with server libs (including servlet api), that can be assigned to your project. However, then everybody that uses your project, need to create the same type of runtime in his/her eclipse workspace even for compiling.
If you directly download the servlet api jar, than it could lead to problems, since it will be included into the artifacts of your projects, but will be also present in servlet container.
In Maven it is much nicer, since you can define the servlet api interfaces as a "provided" dependency, that means it is present in the "to be production" environment.
Simply add
android:keepScreenOn="true"
or call
setKeepScreenOn(true)
on parent view.
I just wanted to share some of my results...
I have text files, which apparently came from a Linux system, so I only have a vbLF
/Chr(10)
at the end of each line and not vbCR
/Chr(13)
.
Note 1:
- This meant that the
Line Input
method would read in the entire file, instead of just one line at a time.
From my research testing small (152KB) & large (2778LB) files, both on and off the network I found the following:
Open FileName For Input: Line Input
was the slowest (See Note 1 above)
Open FileName For Binary Access Read: Input
was the fastest for reading the whole file
FSO.OpenTextFile: ReadLine
was fast, but a bit slower then Binary Input
Note 2:
If I just needed to check the file header (first 1-2 lines) to check if I had the proper file/format, then
FSO.OpenTextFile
was the fastest, followed very closely byBinary Input
.The drawback with the
Binary Input
is that you have to know how many characters you want to read.- On normal files,
Line Input
would also be a good option as well, but I couldn't test due to Note 1.
Note 3:
- Obviously, the files on the network showed the largest difference in read speed. They also showed the greatest benefit from reading the file a second time (although there are certainly memory buffers that come into play here).

Reference:
Yes, it is a bit puzzling at first.
In Ruby, methods may receive a code block in order to perform arbitrary segments of code.
When a method expects a block, it invokes it by calling the yield
function.
This is very handy, for instance, to iterate over a list or to provide a custom algorithm.
Take the following example:
I'm going to define a Person
class initialized with a name, and provide a do_with_name
method that when invoked, would just pass the name
attribute, to the block received.
class Person
def initialize( name )
@name = name
end
def do_with_name
yield( @name )
end
end
This would allow us to call that method and pass an arbitrary code block.
For instance, to print the name we would do:
person = Person.new("Oscar")
#invoking the method passing a block
person.do_with_name do |name|
puts "Hey, his name is #{name}"
end
Would print:
Hey, his name is Oscar
Notice, the block receives, as a parameter, a variable called name
(N.B. you can call this variable anything you like, but it makes sense to call it name
). When the code invokes yield
it fills this parameter with the value of @name
.
yield( @name )
We could provide another block to perform a different action. For example, reverse the name:
#variable to hold the name reversed
reversed_name = ""
#invoke the method passing a different block
person.do_with_name do |name|
reversed_name = name.reverse
end
puts reversed_name
=> "racsO"
We used exactly the same method (do_with_name
) - it is just a different block.
This example is trivial. More interesting usages are to filter all the elements in an array:
days = ["monday", "tuesday", "wednesday", "thursday", "friday"]
# select those which start with 't'
days.select do | item |
item.match /^t/
end
=> ["tuesday", "thursday"]
Or, we can also provide a custom sort algorithm, for instance based on the string size:
days.sort do |x,y|
x.size <=> y.size
end
=> ["monday", "friday", "tuesday", "thursday", "wednesday"]
I hope this helps you to understand it better.
BTW, if the block is optional you should call it like:
yield(value) if block_given?
If is not optional, just invoke it.
EDIT
@hmak created a repl.it for these examples: https://repl.it/@makstaks/blocksandyieldsrubyexample
I used the Multiple SCMs Plugin in conjunction with the Git Plugin successfully with Jenkins.
If you're using ng-view
in your Angular app you can listen for the $viewContentLoaded
event and push a tracking event to Google Analytics.
Assuming you've set up your tracking code in your main index.html file with a name of var _gaq
and MyCtrl is what you've defined in the ng-controller
directive.
function MyCtrl($scope, $location, $window) {
$scope.$on('$viewContentLoaded', function(event) {
$window._gaq.push(['_trackPageView', $location.url()]);
});
}
UPDATE: for new version of google-analytics use this one
function MyCtrl($scope, $location, $window) {
$scope.$on('$viewContentLoaded', function(event) {
$window.ga('send', 'pageview', { page: $location.url() });
});
}
On my Ubuntu VM, with 1048 MB total RAM, java -XX:+PrintFlagsFinal -version | grep HeapSize
printed : uintx MaxHeapSize := 266338304
, which is approx 266MB and is 1/4th of my total RAM.
if not exists (select * from sysobjects where name='cars' and xtype='U')
create table cars (
Name varchar(64) not null
)
go
The above will create a table called cars
if the table does not already exist.
var defaultSettings = {
ajaxsettings: {},
uisettings: {}
};
Take a look at this site: http://www.json.org/
Also, you can try calling JSON.stringify() on one of your objects from the browser to see the json format. You'd have to do this in the console or a test page.
You can use javascript to redirect after some time
setTimeout(function () {
window.location.href= 'http://www.google.com'; // the redirect goes here
},5000); // 5 seconds

I have worked alot with msaccess vba. I think you are looking for MID function
example
dim myReturn as string
myreturn = mid("bonjour tout le monde",9,4)
will give you back the value "tout"
"Curly Braces" are used in Python to define a dictionary. A dictionary is a data structure that maps one value to another - kind of like how an English dictionary maps a word to its definition.
Python:
dict = {
"a" : "Apple",
"b" : "Banana",
}
They are also used to format strings, instead of the old C style using %, like:
ds = ['a', 'b', 'c', 'd']
x = ['has_{} 1'.format(d) for d in ds]
print x
['has_a 1', 'has_b 1', 'has_c 1', 'has_d 1']
They are not used to denote code blocks as they are in many "C-like" languages.
C:
if (condition) {
// do this
}
Use the Node.js console.time()
and console.timeEnd()
:
var i;
console.time("dbsave");
for(i = 1; i < LIMIT; i++){
db.users.save({id : i, name : "MongoUser [" + i + "]"}, end);
}
end = function(err, saved) {
console.log(( err || !saved )?"Error":"Saved");
if(--i === 1){console.timeEnd("dbsave");}
};
If they're actually managed assemblies, you can use ILMerge. For native DLLs, you'll have a bit more work to do.

Just type import pdb
in jupyter notebook, and then use this cheatsheet to debug. It's very convenient.
c
--> continue, s
--> step, b 12
--> set break point at line 12 and so on.

If you're using SQLite version 3.3+ you can easily create a table with:
create table if not exists TableName (col1 typ1, ..., colN typN)
In the same way, you can remove a table only if it exists by using:
drop table if exists TableName
1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.
2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):
This rule will do SINGLE EXACT rewrite (internal redirect) /page
to /page.html
. URL in browser will remain unchanged.
<system.webServer>
<rewrite>
<rules>
<rule name="SpecificRewrite" stopProcessing="true">
<match url="^page$" />
<action type="Rewrite" url="/page.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.
<system.webServer>
<rewrite>
<rules>
<rule name="SpecificRedirect" stopProcessing="true">
<match url="^page$" />
<action type="Redirect" url="/page.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page
it will check if /page.html
exists, and if it does then rewrite occurs):
<system.webServer>
<rewrite>
<rules>
<rule name="DynamicRewrite" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{REQUEST_FILENAME}\.html" matchType="IsFile" />
</conditions>
<action type="Rewrite" url="/{R:1}.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
Just add this in you styles.xml. The colorPrimary is for the action bar and the colorPrimaryDark is for the status bar.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:colorPrimary">@color/primary</item>
<item name="android:colorPrimaryDark">@color/primary_dark</item>
</style>
This picture from developer android explains more about color pallete. You can read more on this link.
From my end, I have tried all these and none of them worked. The most probable problem with this is that you have added more than one dependency, hence it is mandatory to wrap them in a <dependencies> </dependencies>
tag. Hope it helps!
you can use :
$('#timePicker').datetimepicker({
format:'d.m.Y H:i',
minDate: ge_today_date(new Date())
});
function ge_today_date(date) {
var day = date.getDate();
var month = date.getMonth() + 1;
var year = date.getFullYear().toString().slice(2);
return day + '-' + month + '-' + year;
}
Another approach which seemed to work for me at least in Linux environment is to run your Node.js application like this:
env TZ='Europe/Amsterdam' node server.js
This should at least ensure that the timezone is correctly set already from the beginning.
In case you need to the use basic authorisation for your proxy provider, just use the following:
var http = require("http");
var options = {
host: FarmerAdapter.PROXY_HOST,
port: FarmerAdapter.PROXY_PORT,
path: requestedUrl,
headers: {
'Proxy-Authorization': 'Basic ' + new Buffer(FarmerAdapter.PROXY_USER + ':' + FarmerAdapter.PROXY_PASS).toString('base64')
}
};
var request = http.request(options, function(response) {
var chunks = [];
response.on('data', function(chunk) {
chunks.push(chunk);
});
response.on('end', function() {
console.log('Response', Buffer.concat(chunks).toString());
});
});
request.on('error', function(error) {
console.log(error.message);
});
request.end();
If you are using Eclipse, this should be easy:
1.Press Alt+Shift+S
2.Choose "Generate toString()..."
Enjoy! You can have any template of toString()s.
This also works with getter/setters.
Facing the same issue with the error described by Garrett above. 1. MongoDB Server with journaling enabled is running as seen using ps command 2. Mongo client or Mongoose driver are unable to connect to the database.
Solution : 1. Deleting the Mongo.lock file seems to bring life back to normal on the CentOS server. 2. We are fairly new in running MongoDB in production and have been seeing the same issue cropping up a couple of times a week. 3. We've setup a cron schedule to regularly cleanup the lock file and intimate the admin that an incident has occurred.
Searching for a bug fix to this issue or any other more permanent way to resolve it.

The fully-qualified name is opbtained as follows:
String fqn = YourClass.class.getName();
But you need to read a classpath resource. So use
InputStream in = YourClass.getResourceAsStream("resource.txt");
u can try this..
<div id="placeholder" style="width:auto;height:auto"></div>
width and height depends on your flot or graph..
hope u want this...
or
By clicking, u can use this by jquery
$("#placeholder").css("width", $(window).width());
$("#placeholder").css("height", $(window).height());
I have a very simple solution for this problem. You don't need to use the console.
TLDR: Create repo, move files to existing projects folder, SourceTree will ask you where his files are, locate the files. Done, your repo is in another folder.
Long answer:
Tips: Clone in SourceTree option is not available right after you create new repository so you first have to click on Create Readme File for that option to become available.
As Hemerson Varela already said in Php 7.1 count(null)
will throw an error
and hasOne
returns null
if no row exists. Since you have a hasOne
relation I would use the empty
method to check:
$model = RepairItem::find($id);
if (!empty($temp = $request->input('option'))) {
$option = $model->option;
if(empty($option)){
$option = $model->option()->create();
}
$option->someAttribute = temp;
$option->save();
};
But this is superfluous. There is no need to check if the relation exists, to determine if you should do an update
or a create
call. Simply use the updateOrCreate method. This is equivalent to the above:
$model = RepairItem::find($id);
if (!empty($temp = $request->input('option'))) {
$model->option()
->updateOrCreate(['repair_item_id' => $model->id],
['option' => $temp]);
}
Currently Angular CLI doesn't support the feature of renaming or refactoring code.
You can achieve such functionality with the help of some IDE.
Intellij, Eclipse, VSCode etc.. has default support the refactoring.
Nowadays VSCode is showing some uptrend,personally I'm a fan of this
Refactoring with VSCode
Determinig reference : -
VS Code help you find all references of a variable by selecting variable and pressing shortcut SHIFT
+ F12
. This works incredibly well with Type Script.
Renaming all instances of reference :-
After finding all the references you can press F2
will open a popup and you can change the value and click enter this will update all the instances of reference.
Renaming files and imports You can rename a file and its import references with a plugin. More details can be found here
With above steps after renaming the variables and files you can achieve the angular component renaming.
In newer versions of Git for Windows, Bash is started with --login
which causes Bash to not read .bashrc
directly. Instead it reads .bash_profile
.
If this file does not exist, create it with the following content:
if [ -f ~/.bashrc ]; then . ~/.bashrc; fi
This will cause Bash to read the .bashrc
file. From my understanding of this issue, Git for Windows should do this automatically. However, I just installed version 2.5.1, and it did not.
A change was introduced recently in how Facebook handles session redirects. See "Change in Session Redirect Behavior" in this week's Operation Developer Love blog post for the announcement.
Building on top of Mike Causer's answer I've made this function which takes into consideration multiple params with the same key (foo=bar&foo=baz
) and also comma-separated parameters (foo=bar,baz,bin
). It also lets you search for a certain query key.
function getQueryParams(queryKey) {
var queryString = window.location.search;
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
var key = decodeURIComponent(pair[0]);
var value = decodeURIComponent(pair[1] || '');
// Se possui uma vírgula no valor, converter em um array
value = (value.indexOf(',') === -1 ? value : value.split(','));
// Se a key já existe, tratar ela como um array
if (query[key]) {
if (query[key].constructor === Array) {
// Array.concat() faz merge se o valor inserido for um array
query[key] = query[key].concat(value);
} else {
// Se não for um array, criar um array contendo o valor anterior e o novo valor
query[key] = [query[key], value];
}
} else {
query[key] = value;
}
}
if (typeof queryKey === 'undefined') {
return query;
} else {
return query[queryKey];
}
}
Example input:
foo.html?foo=bar&foo=baz&foo=bez,boz,buz&bar=1,2,3
Example output
{
foo: ["bar","baz","bez","boz","buz"],
bar: ["1","2","3"]
}
You can also solve this problem without changing code in server, changing header in $http.post
call and use $_POST
the regular way. Explained here: http://victorblog.com/2012/12/20/make-angularjs-http-service-behave-like-jquery-ajax/
Set the following two environment variables:
NVIDIA_VISIBLE_DEVICES=$gpu_id
CUDA_VISIBLE_DEVICES=0
where gpu_id
is the ID of your selected GPU, as seen in the host system's nvidia-smi
(a 0-based integer) that will be made available to the guest system (e.g. to the Docker container environment).
You can verify that a different card is selected for each value of gpu_id by inspecting Bus-Id
parameter in nvidia-smi
run in a terminal in the guest system).
This method based on NVIDIA_VISIBLE_DEVICES
exposes only a single card to the system (with local ID zero), hence we also hard-code the other variable, CUDA_VISIBLE_DEVICES
to 0 (mainly to prevent it from defaulting to an empty string that would indicate no GPU).
Note that the environmental variable should be set before the guest system is started (so no chances of doing it in your Jupyter Notebook's terminal), for instance using docker run -e NVIDIA_VISIBLE_DEVICES=0
or env
in Kubernetes or Openshift.
If you want GPU load-balancing, make gpu_id
random at each guest system start.
If setting this with python, make sure you are using strings for all environment variables, including numerical ones.
You can verify that a different card is selected for each value of gpu_id
by inspecting nvidia-smi
's Bus-Id parameter (in a terminal run in the guest system).
The accepted solution based on CUDA_VISIBLE_DEVICES
alone does not hide other cards (different from the pinned one), and thus causes access errors if you try to use them in your GPU-enabled python packages. With this solution, other cards are not visible to the guest system, but other users still can access them and share their computing power on an equal basis, just like with CPU's (verified).
This is also preferable to solutions using Kubernetes / Openshift controlers (resources.limits.nvidia.com/gpu
), that would impose a lock on the allocated card, removing it from the pool of available resources (so the number of containers with GPU access could not exceed the number of physical cards).
This has been tested under CUDA 8.0, 9.0 and 10.1 in docker containers running Ubuntu 18.04 orchestrated by Openshift 3.11.
Using jQuery ...
$(document).height() & $(window).height() will return the same values ... the key is to reset body's padding and margin so that you get no scrolling.
<!--
body {
padding: 0px;
margin: 0px;
position: relative;
}
-->
Hope this helps.
Convert Date to String using this function

String dateStr = null;
DateFormat df = new SimpleDateFormat(format);
try {
dateStr = df.format(date);
} catch (Exception ex) {
System.out.println(ex);
}
return dateStr;
}
From Convert Date to String in Java . And convert string to date again
public Date convertStringToDate(String dateStr, String format) {

DateFormat df = new SimpleDateFormat(format);
try {
date = df.parse(dateStr);
} catch (Exception ex) {

Best way would be to declare Boolean
variable within the code block and return
it at end of code, like this:
public boolean Test(){
boolean booleanFlag= true;
if (A>B)
{booleanFlag= true;}
else
{booleanFlag = false;}
return booleanFlag;
}
I find this the best way.
Unfortunately, not in the .Net BCL. Dates are usually represented as a DateTime object with the time set to midnight.
As you can guess, this means that you have all the attendant timezone issues around it, even though for a Date object you'd want absolutely no timezone handling.
In phpstorm + vagrant autoReconnect driver option helped.
I have this function for this case ..
Function GetValue(r As Range, Tag As String) As Integer
Dim c, nRet As String
Dim n, x As Integer
Dim bNum As Boolean
c = r.Value
n = InStr(c, Tag)
For x = n + 1 To Len(c)
Select Case Mid(c, x, 1)
Case ":": bNum = True
Case " ": Exit For
Case Else: If bNum Then nRet = nRet & Mid(c, x, 1)
End Select
Next
GetValue = val(nRet)
End Function
To fill cell BC .. (assumed that you check cell A1)
Worksheets("Übersicht_2013").Cells(i, "BC") = GetValue(range("A1"),"S")
Following @rsplak answer: actually, using split/join way is faster than using regexp. See the performance test case
So
var result = text.split(' ').join('')
operates faster than
var result = text.replace(/\s+/g, '')
On small texts this is not relevant, but for cases when time is important, e.g. in text analisers, especially when interacting with users, that is important.
On the other hand, \s+
handles wider variety of space characters. Among with \n
and \t
, it also matches \u00a0
character, and that is what
is turned in, when getting text using textDomNode.nodeValue
.
So I think that conclusion in here can be made as follows: if you only need to replace spaces ' '
, use split/join. If there can be different symbols of symbol class - use replace(/\s+/g, '')
I wrote more universal solution based on @Fer answer.
It also should work with flavor and build type based configuration of applicationId
, versionName
, versionCode
.
In the build.gradle:
android {
...
applicationVariants.all { variant ->
variant.outputs.each { output ->
def appId = variant.applicationId
def versionName = variant.versionName
def versionCode = variant.versionCode
def flavorName = variant.flavorName // e. g. free
def buildType = variant.buildType // e. g. debug
def variantName = variant.name // e. g. freeDebug
def apkName = appId + '_' + variantName + '_' + versionName + '_' + versionCode + '.apk';
output.outputFile = new File(output.outputFile.parentFile, apkName)
}
}
}
Example apk name: com.example.app_freeDebug_1.0_1.apk
For more information about variant
variable see ApkVariant and BaseVariant interfaces definition.
Because you are creatin a table expression, you have to specify the structure of that table, you can achive this on two way:
1: In the select you can use the original columnnames (as in your first example), but with aggregates you have to use an alias (also in conflicting names). Like
sum(totalitems) as bkdqty
2: You need to specify the column names rigth after the name of the talbe, and then you just have to take care that the count of the names should mach the number of coulms was selected in the query. Like:

With the second solution both of your query will work!
I ended up going with a shell script that you should only really have to run once when you first checkout a project
#!/usr/bin/env bash
mkdir -p webroot/js
mkdir -p webroot/css
mkdir -p webroot/css-min
mkdir -p webroot/img
mkdir -p webroot/font
npm i
bower i
# boostrap
pushd components/bootstrap
npm i
make bootstrap
popd
cp components/bootstrap/bootstrap/css/*.min.css webroot/css-min/
cp components/bootstrap/bootstrap/js/bootstrap.js src/js/deps/
cp components/bootstrap/bootstrap/img/* webroot/img/
# fontawesome
cp components/font-awesome/css/*.min.css webroot/css-min/
cp components/font-awesome/font/* webroot/font/
font/woff2
For nginx add the following to the mime.types
file:
font/woff2 woff2;
Old Answer
The mime type (sometime written as mimetype) for WOFF2 fonts has been proposed as application/font-woff2
.
Also, if you refer to the spec (http://dev.w3.org/webfonts/WOFF2/spec/) you will see that font/woff2
is being discussed. I suspect that the filal mime type for all fonts will eventually be the more logical font/*
(font/ttf
, font/woff2
etc)...
N.B. WOFF2 is still in 'Working Draft' status -- not yet adopted officially.
In Rails, it has form_for helper, so we could make a function like form_for.
We can make a Form macro, for example in resource/macro/html.php:
(if you don't know how to setup a macro, you can google "laravel 5 Macro")
Form::macro('start', function($record, $resource, $options = array()){
if ((null === $record || !$record->exists()) ? 1 : 0) {
$options['route'] = $resource .'.store';
$options['method'] = 'POST';
$str = Form::open($options);
} else {
$options['route'] = [$resource .'.update', $record->id];
$options['method'] = 'PUT';
$str = Form::model($record, $options);
}
return $str;
});
The Controller:
public function create()
{
$category = null;
return view('admin.category.create', compact('category'));
}
public function edit($id)
{
$category = Category.find($id);
return view('admin.category.edit', compact('category'));
}
Then in the view _form.blade.php:
{!! Form::start($category, 'admin.categories', ['class' => 'definewidth m20']) !!}
// here the Form fields
{{!! Form::close() !!}}
Then view create.blade.php:
@include '_form'
Then view edit.blade.php:
@include '_form'
use like this your inline css
<td width="178" rowspan="3" valign="top"
align="right" background="images/left.jpg"
style="background-repeat:background-position: right top;">
</td>
The frankly-incredible data-analysis library for Python called Pandas
has a function to read Stata files.
After installing Pandas
you can just do:
>>> import pandas as pd
>>> data = pd.io.stata.read_stata('my_stata_file.dta')
>>> data.to_csv('my_stata_file.csv')
Amazing!
The goal you indicate in the command line is linked to the lifecycle of Maven. For example, the build
lifecycle (you also have the clean
and site
lifecycles which are different) is composed of the following phases:
validate
: validate the project is correct and all necessary information is available.compile
: compile the source code of the project.test
: test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed.package
: take the compiled code and package it in its distributable format, such as a JAR.integration-test
: process and deploy the package if necessary into an environment where integration tests can be run.verify
: run any checks to verify the package is valid and meets quality criteriainstall
: install the package into the local repository, for use as a dependency in other projects locally.deploy
: done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.You can find the list of "core" plugins here, but there are plenty of others plugins, such as the codehaus ones, here.
As an addition to e.g. @Intrepidd s answer, in certain situations you want to use fetch
instead of []
. For fetch
not to throw an exception when the key is not found, pass it a default value.
puts "ok" if hash.fetch('key', nil) == 'X'
Reference: https://docs.ruby-lang.org/en/2.3.0/Hash.html .
Avoiding redundancy I don't repeat my answer here again.
Please refer to my answer here. (note that answer only covers compiling to python bytecode.)
I am surprise, no one here has ans by using simple javascript
and Set
logic to automatically filter the duplicates values, simple example on mongo shellas below:
var allKeys = new Set()
db.collectionName.find().forEach( function (o) {for (key in o ) allKeys.add(key)})
for(let key of allKeys) print(key)
This will print all possible unique keys in the collection name: collectionName.
It is probably not a correct way for clean, but I made that to delete unnecessary files, and take less size of a project. It continuously finds and deletes all build and Gradle folders made file clean.bat copy that into the folder where your project is
set mypath=%cd%
for /d /r %mypath% %%a in (build\) do if exist "%%a" rmdir /s /q "%%a"
for /d /r %mypath% %%a in (.gradle\) do if exist "%%a" rmdir /s /q "%%a"
If your code, if the user enters 'X' (for instance), when you reach the while condition evaluation it will determine that 'X' is differente from 'n' (nChar != 'n') which will make your loop condition true and execute the code inside of your loop. The second condition is not even evaluated.
You can also move mounted
out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.
function init() {
// Use `this` normally
}
new Vue({
methods:{
init
},
mounted(){
init.call(this)
}
})
$ch = curl_init();
$data = array(
'client_id' => 'xx',
'client_secret' => 'xx',
'redirect_uri' => $x,
'grant_type' => 'xxx',
'code' => $xx,
);
$data = http_build_query($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, "https://example.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
$output = curl_exec($ch);
If you want to ignore lines with only whitespace:
if not line.strip():
... do something
The empty string is a False value.
Or if you really want only empty lines:
if line in ['\n', '\r\n']:
... do something
Previous answers are correct but here is one more way of doing this and some tips:
Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there
Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh
things to watch for /tips:
Try moving the lapsList
function out of your class and into your render function:
render() {
const lapsList = this.state.laps.map((data) => {
return (
<View><Text>{data.time}</Text></View>
)
})
return (
<View style={styles.container}>
<View style={styles.footer}>
<View><Text>coucou test</Text></View>
{lapsList}
</View>
</View>
)
}
function sendemail(Array $id,$userid){ // forces $id must be an array
Some Process....
}
$ids = array(121,122,123);
sendmail($ids, $userId);
I finally understood the problem:
methodA() {
methodB()
}
@Transactional(noRollbackFor = Exception.class)
methodB() {
...
try {
methodC()
} catch (...) {...}
log("OK");
}
@Transactional
methodC() {
throw new ...();
}
What happens is that even though the methodB
has the right annotation, the methodC
does not. When the exception is thrown, the second @Transactional
marks the first transaction as Rollback only anyway.
you can for example remove all other chars and count the whats remains, like:
var="text,text,text,text"
res="${var//[^,]}"
echo "$res"
echo "${#res}"
will print
,,,
3
or
tr -dc ',' <<<"$var" | awk '{ print length; }'
or
tr -dc ',' <<<"$var" | wc -c #works, but i don't like wc.. ;)
or
awk -F, '{print NF-1}' <<<"$var"
or
grep -o ',' <<<"$var" | grep -c .
or
perl -nle 'print s/,//g' <<<"$var"
It is very easy using removeAttr.
$(element).removeAttr("onclick");
You can use filter
, like so:
$desired_object = $food->filter(function($item) {
return $item->id == 24;
})->first();
filter
will also return a Collection
, but since you know there will be only one, you can call first
on that Collection
.
You don't need the filter anymore (or maybe ever, I don't know this is almost 4 years old). You can just use first
:
$desired_object = $food->first(function($item) {
return $item->id == 24;
});
You have to do this:
class Bar : public Foo
{
// ...
}
The default inheritance type of a class
in C++ is private
, so any public
and protected
members from the base class are limited to private
. struct
inheritance on the other hand is public
by default.
or you can use package doBy
library(doBy)
dd <- orderBy(~-z+b, data=dd)
In addition what others mentioned here, note that combining the Application.DispatcherUnhandledException
(and its similars) with
<configuration>
<runtime>
<legacyUnhandledExceptionPolicy enabled="1" />
</runtime>
</configuration>
in the app.config
will prevent your secondary threads exception from shutting down the application.
IMHO there is one great svn gui client, SmartSVN. It is commercial project, but there is foundation version (100% functional) witch can be used free of charge, even for commercial purposes. It is written in java, so it is multi-platform (it requires sun-java* package) http://smartsvn.com
Object.defineProperty(Array.prototype, "last", {_x000D_
get: function() {_x000D_
if (this[this.length -1] == undefined) { return [] }_x000D_
else { return this[this.length -1] }_x000D_
}_x000D_
});_x000D_
_x000D_
console.log([1,2,3,4].last) //returns 4

Even though there are already many many answers to this post, I feel I have to add another option for unix hosts that only returns the sum of all file sizes in the directory (recursively).
If you look at Jonathan's answer he uses the du
command. This command will return the total directory size but the pure PHP solutions posted by others here will return the sum of all file sizes. Big difference!
When running du
on a newly created directory, it may return 4K
instead of 0
. This may even get more confusing after having deleted files from the directory in question, having du
reporting a total directory size that does not correspond to the sum of the sizes of the files within it. Why? The command du
returns a report based on some file settings, as Hermann Ingjaldsson commented on this post.
To form a solution that behaves like some of the PHP-only scripts posted here, you can use ls
command and pipe it to awk
like this:
ls -ltrR /path/to/dir |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'
As a PHP function you could use something like this:
function getDirectorySize( $path )
{
if( !is_dir( $path ) ) {
return 0;
}
$path = strval( $path );
$io = popen( "ls -ltrR {$path} |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'", 'r' );
$size = intval( fgets( $io, 80 ) );
pclose( $io );
return $size;
}
What happens if you get rid of the stringwriter:
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=adressenbestand.csv");
Response.ContentType = "text/csv";
//write the header
Response.Write(String.Format("{0},{1},{2},{3}", CMSMessages.EmailAddress, CMSMessages.Gender, CMSMessages.FirstName, CMSMessages.LastName));
//write every subscriber to the file
var resourceManager = new ResourceManager(typeof(CMSMessages));
foreach (var record in filterRecords.Select(x => x.First().Subscriber))
{
Response.Write(String.Format("{0},{1},{2},{3}", record.EmailAddress, record.Gender.HasValue ? resourceManager.GetString(record.Gender.ToString()) : "", record.FirstName, record.LastName));
}
Response.End();
Usually when i try to find my public IP Address like cmyip.com or www.iplocation.net, i use this way:
public static String myPublicIp() {
/*nslookup myip.opendns.com resolver1.opendns.com*/
String ipAdressDns = "";
try {
String command = "nslookup myip.opendns.com resolver1.opendns.com";
Process proc = Runtime.getRuntime().exec(command);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String s;
while ((s = stdInput.readLine()) != null) {
ipAdressDns += s + "\n";
}
} catch (IOException e) {
e.printStackTrace();
}
return ipAdressDns ;
}
Add icon: https://developer.android.com/studio/write/vector-asset-studio.html
set icon: setIcon(R.drawable.ic_incon_name)
Change
$info=$_POST['id[]'];
to
$info=$_POST['id'];
by adding []
to the end of your form field names, PHP will automatically convert these variables into arrays.
Although the other answers posted here work, I find the following approach more natural:
$obj = (object) [
'aString' => 'some string',
'anArray' => [ 1, 2, 3 ]
];
echo json_encode($obj);
I am adding this answer in case someone else would like to store the host entry set in a txt file formatted like the normal host file. This looks for a TAB delimiter. This is based off of the answers from @Rashy and @that0n3guy. The differences can be noticed around the FOR command.

I wrapped around $state
around $timeout
and it worked for me.
For example,
(function() {
'use strict';
angular
.module('app')
.controller('BodyController', BodyController);
BodyController.$inject = ['$state', '$timeout'];
/* @ngInject */
function BodyController($state, $timeout) {
$timeout(function(){
console.log($state.current);
});
}
})();
Since you add ..
after cmake, it will jump up and up (just like cd ..
) in the directory. But if you want to run cmake under the same folder with CMakeLists.txt, please use .
instead of ..
.
It's not an error. Javascript will gladly convert a number to a string when a string is expected (for example parseInt(42)
), but in this case there is nothing that expect the number to be a string.
Here's a makeLowerCase
function. :)
function makeLowerCase(value) {
return value.toString().toLowerCase();
}
If you want to denote an actual error in your code, you could raise a RuntimeError
exception:
raise RuntimeError, 'Message goes here'
This will print a stacktrace, the type of the exception being raised and the message that you provided. Depending on your users, a stacktrace might be too scary, and the actual message might get lost in the noise. On the other hand, if you die because of an actual error, a stacktrace will give you additional information for debugging.
Another thing I like to do is creating an object and then looping thru the object and setting the styles like that because it can be tedious writing every single style one by one.
var bookStyles = {
color: "red",
backgroundColor: "blue",
height: "300px",
width: "200px"
};
let div = document.createElement("div");
for (let style in bookStyles) {
div.style[style] = bookStyles[style];
}
body.appendChild(div);
I was trying to test an extjs application and after sucessfully setting a testingAuthenticationToken this suddenly stopped working with no obvious cause.
I couldn't get the above answers to work so my solution was to skip out this bit of spring in the test environment. I introduced a seam around spring like this:
public class SpringUserAccessor implements UserAccessor
{
@Override
public User getUser()
{
SecurityContext context = SecurityContextHolder.getContext();
Authentication authentication = context.getAuthentication();
return (User) authentication.getPrincipal();
}
}
User is a custom type here.
I'm then wrapping it in a class which just has an option for the test code to switch spring out.
public class CurrentUserAccessor
{
private static UserAccessor _accessor;
public CurrentUserAccessor()
{
_accessor = new SpringUserAccessor();
}
public User getUser()
{
return _accessor.getUser();
}
public static void UseTestingAccessor(User user)
{
_accessor = new TestUserAccessor(user);
}
}
The test version just looks like this:
public class TestUserAccessor implements UserAccessor
{
private static User _user;
public TestUserAccessor(User user)
{
_user = user;
}
@Override
public User getUser()
{
return _user;
}
}
In the calling code I'm still using a proper user loaded from the database:
User user = (User) _userService.loadUserByUsername(username);
CurrentUserAccessor.UseTestingAccessor(user);
Obviously this wont be suitable if you actually need to use the security but I'm running with a no-security setup for the testing deployment. I thought someone else might run into a similar situation. This is a pattern I've used for mocking out static dependencies before. The other alternative is you can maintain the staticness of the wrapper class but I prefer this one as the dependencies of the code are more explicit since you have to pass CurrentUserAccessor into classes where it is required.

"What is a stored procedure" is already answered in other posts here. What I will post is one less known way of using stored procedure. It is grouping stored procedures
or numbering stored procedures
.
Syntax Reference
; number
as per this
An optional integer that is used to group procedures of the same name. These grouped procedures can be dropped together by using one DROP PROCEDURE statement
Example
CREATE Procedure FirstTest
(
@InputA INT
)
AS
BEGIN
SELECT 'A' + CONVERT(VARCHAR(10),@InputA)
END
GO
CREATE Procedure FirstTest;2
(
@InputA INT,
@InputB INT
)
AS
BEGIN
SELECT 'A' + CONVERT(VARCHAR(10),@InputA)+ CONVERT(VARCHAR(10),@InputB)
END
GO
Use
exec FirstTest 10
exec FirstTest;2 20,30
Result
Another Attempt
CREATE Procedure SecondTest;2
(
@InputA INT,
@InputB INT
)
AS
BEGIN
SELECT 'A' + CONVERT(VARCHAR(10),@InputA)+ CONVERT(VARCHAR(10),@InputB)
END
GO
Result
Msg 2730, Level 11, State 1, Procedure SecondTest, Line 1 [Batch Start Line 3] Cannot create procedure 'SecondTest' with a group number of 2 because a procedure with the same name and a group number of 1 does not currently exist in the database. Must execute CREATE PROCEDURE 'SecondTest';1 first.
References:
CAUTION
Use a double for the sum, otherwise you are doing an integer division and you won't get any decimals:
private double calculateAverage(List <Integer> marks) {
if (marks == null || marks.isEmpty()) {
return 0;
}
double sum = 0;
for (Integer mark : marks) {
sum += mark;
}
return sum / marks.size();
}
or using the Java 8 stream API:
return marks.stream().mapToInt(i -> i).average().orElse(0);
It is difficult to choose which one is better; lock or ReaderWriterLockSlim. You need real world statistics of read and write numbers and ratios etc.
But if you believe using "lock" is the correct way. Then here is a different solution for different needs. I also include the Allan Xu's solution in the code. Because both can be needed for different needs.
Here are the requirements, driving me to this solution:

Unless there is some other requirement not specified, I would simply convert your color image to grayscale and work with that only (no need to work on the 3 channels, the contrast present is too high already). Also, unless there is some specific problem regarding resizing, I would work with a downscaled version of your images, since they are relatively large and the size adds nothing to the problem being solved. Then, finally, your problem is solved with a median filter, some basic morphological tools, and statistics (mostly for the Otsu thresholding, which is already done for you).
Here is what I obtain with your sample image and some other image with a sheet of paper I found around:
The median filter is used to remove minor details from the, now grayscale, image. It will possibly remove thin lines inside the whitish paper, which is good because then you will end with tiny connected components which are easy to discard. After the median, apply a morphological gradient (simply dilation
- erosion
) and binarize the result by Otsu. The morphological gradient is a good method to keep strong edges, it should be used more. Then, since this gradient will increase the contour width, apply a morphological thinning. Now you can discard small components.
At this point, here is what we have with the right image above (before drawing the blue polygon), the left one is not shown because the only remaining component is the one describing the paper:
Given the examples, now the only issue left is distinguishing between components that look like rectangles and others that do not. This is a matter of determining a ratio between the area of the convex hull containing the shape and the area of its bounding box; the ratio 0.7 works fine for these examples. It might be the case that you also need to discard components that are inside the paper, but not in these examples by using this method (nevertheless, doing this step should be very easy especially because it can be done through OpenCV directly).
For reference, here is a sample code in Mathematica:
f = Import["http://thwartedglamour.files.wordpress.com/2010/06/my-coffee-table-1-sa.jpg"]

If there are more varied situations where the paper's rectangle is not so well defined, or the approach confuses it with other shapes -- these situations could happen due to various reasons, but a common cause is bad image acquisition -- then try combining the pre-processing steps with the work described in the paper "Rectangle Detection based on a Windowed Hough Transform".
My solution is:
public static Bitmap loadBitmapFromView(Context context, View v) {
DisplayMetrics dm = context.getResources().getDisplayMetrics();
v.measure(MeasureSpec.makeMeasureSpec(dm.widthPixels, MeasureSpec.EXACTLY),
MeasureSpec.makeMeasureSpec(dm.heightPixels, MeasureSpec.EXACTLY));
v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
Bitmap returnedBitmap = Bitmap.createBitmap(v.getMeasuredWidth(),
v.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(returnedBitmap);
v.draw(c);
return returnedBitmap;
}
and
public void takeScreen() {
Bitmap bitmap = ImageUtils.loadBitmapFromView(this, view); //get Bitmap from the view
String mPath = Environment.getExternalStorageDirectory() + File.separator + "screen_" + System.currentTimeMillis() + ".jpeg";
File imageFile = new File(mPath);
OutputStream fout = null;
try {
fout = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
fout.flush();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
fout.close();
}
}
Images are saved in the external storage folder.

As stated in the answer by Henrik, titles are left-aligned by default starting with ggplot 2.2.0. Titles can be centered by adding this to the plot:
theme(plot.title = element_text(hjust = 0.5))
However, if you create many plots, it may be tedious to add this line everywhere. One could then also change the default behaviour of ggplot with
theme_update(plot.title = element_text(hjust = 0.5))
Once you have run this line, all plots created afterwards will use the theme setting plot.title = element_text(hjust = 0.5)
as their default:
theme_update(plot.title = element_text(hjust = 0.5))
ggplot() + ggtitle("Default is now set to centered")
To get back to the original ggplot2 default settings you can either restart the R session or choose the default theme with
theme_set(theme_gray())
This method works for Excel 2016, and calculates on cell value, so can be used on formula arrays (i.e. it will ignore blank cells that contain a formula).
Note: Len(#)>0 be altered to only select cell values above a certain length.
Note 2: '#' must not be an absolute reference (i.e. shouldn't contain '$').
This solution is deprecated. Use the top voted solution.
The hide
class is useful to keep the content hidden on page load.
My solution to this is during initialization, switch to jquery's hide:
$('.targets').hide().removeClass('hide');
Then show()
and hide()
should function as normal.
UPDATE: Please see Dylan's or d.c's anwer for a little easier (and more stable) solution, which does not rely on Chrome beeing installed in LocalAppData
!
Even if I agree with Daniel Hilgarth to open a new tab in chrome you just need to execute chrome.exe with your URL as the argument:
Process.Start(@"%AppData%\..\Local\Google\Chrome\Application\chrome.exe",
"http:\\www.YourUrl.com");
Simple!
System.IO.File.WriteAllText(path, text, Encoding.GetEncoding(28591));
Check the "bind-adress"
parameter in my.cnf.
Else try with the command:
mysql -h 127.0.0.1 -P 3306 -u root -p
-h for host 127.0.0.1
, that is, localhost
-P (notice -P as uppercase) for port 3306
, that is, the default port for MySQL
If the constructor of a class is private then you cannot create an object for class from outside of it.
class Test{
int x, y;
private Test(){
.......
.......
}
}
We cannot create an object for above class from outside of it. So you cannot access x, y from outside of the class. Then what is the use of this class?
Here is the Answer : FACTORY method.
Add the below method in above class
public static Test getObject(){
return new Test();
}
So now you can create an object for this class from outside of it. Like the way...
Test t = Test.getObject();
Hence, a static method which returns the object of the class by executing its private constructor is called as FACTORY method
.
This can be achieved using TextEditingController
.
To have an initial value you can add
TextEditingController _controller = TextEditingController(text: 'initial value');
or
If you are using TextFormField
you have a initialValue
property there. Which basically provides this initialValue
to the controller automatically.
TextEditingController _controller = TextEditingController();
TextFormField(
controller: _controller,
initialValue: 'initial value'
)
To clear the text you can use
_controller.clear()
method.
You can have only one default export which you declare like:
export default App;
or
export default class App extends React.Component {...
and later do import App from './App'
If you want to export something more you can use named exports which you declare without default
keyword like:
export {
About,
Contact,
}
or:
export About;
export Contact;
or:
export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);
and later you import them like:
import App, { About, Contact } from './App';
EDIT:
There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js
file. Other than that why export anything if it is no used outside the file?. Correct main.js
:
import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute } from 'react-router'
class App extends React.Component {
...
}
class Home extends React.Component {
...
}
class About extends React.Component {
...
}
class Contact extends React.Component {
...
}
ReactDOM.render((
<Router history = {browserHistory}>
<Route path = "/" component = {App}>
<IndexRoute component = {Home} />
<Route path = "home" component = {Home} />
<Route path = "about" component = {About} />
<Route path = "contact" component = {Contact} />
</Route>
</Router>
), document.getElementById('app'))
EDIT2:
another thing is that this tutorial is based on react-router-V3 which has different api than v4.
For a quick and cheap way to host an angular app, I have been using the Firbase hosting. It's free on the first tier and very easy to deploy new versions using the Firebase CLI. This article here explains the necessary steps to deploy your production angular 2 app to Firebase: https://medium.com/codingthesmartway-com-blog/hosting-angular-2-applications-on-firebase-f194688c978d
In short, you run ng build --prod
which creates a dist folder in the package and that's the folder that gets deployed to Firebase Hosting.
If anyone is looking for an updated correct syntax for this as I was, try the following:
Example:
dg.Rows[0].Cells[6].Value = "test";
set print elements 0
set print elements
number-of-elements
Set a limit on how many elements of an array GDB will print. If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements
command. This limit also applies to the display of strings. When GDB starts, this limit is set to 200. Setting number-of-elements to zero means that the printing is unlimited.
No, it's not possible.
It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".
Ah, got it myselfs.
The quirks and quarks of LINQ-2-entities.
This looks most understandable:
var query2 = (
from users in Repo.T_Benutzer
from mappings in Repo.T_Benutzer_Benutzergruppen
.Where(mapping => mapping.BEBG_BE == users.BE_ID).DefaultIfEmpty()
from groups in Repo.T_Benutzergruppen
.Where(gruppe => gruppe.ID == mappings.BEBG_BG).DefaultIfEmpty()
//where users.BE_Name.Contains(keyword)
// //|| mappings.BEBG_BE.Equals(666)
//|| mappings.BEBG_BE == 666
//|| groups.Name.Contains(keyword)
select new
{
UserId = users.BE_ID
,UserName = users.BE_User
,UserGroupId = mappings.BEBG_BG
,GroupName = groups.Name
}
);
var xy = (query2).ToList();
Remove the .DefaultIfEmpty()
, and you get an inner join.
That was what I was looking for.
Check your error log file and then use the tail command as:
tail -200f /var/log/redis_6379.log
or
tail -200f /var/log/redis.log
According to your error file name..
No, sorry. User-defined functions in SQL Server are really limited, because of a requirement that they be deterministic. No way round it, as far as I know.
Have you tried debugging the SQL code with Visual Studio?
You can use a 3rd party library like Shield UI for charting - that is tested and works well on all legacy and new web browsers and devices.
Also, in some cases is important to check the target folder permissions. To give write permission for the user might be the solution. That worked for me.
Answering my own question about 2 or something years later here but...
It uses a protocol extension so you can do it without any extra code for all classes.
/*
Prerequisites
-------------
- In IB set the view's class to the type hook up any IBOutlets
- In IB ensure the file's owner is blank
*/
public protocol CreatedFromNib {
static func createFromNib() -> Self?
static func nibName() -> String?
}
extension UIView: CreatedFromNib { }
public extension CreatedFromNib where Self: UIView {
public static func createFromNib() -> Self? {
guard let nibName = nibName() else { return nil }
guard let view = NSBundle.mainBundle().loadNibNamed(nibName, owner: nil, options: nil).last as? Self else { return nil }
return view
}
public static func nibName() -> String? {
guard let n = NSStringFromClass(Self.self).componentsSeparatedByString(".").last else { return nil }
return n
}
}
// Usage:
let myView = MyView().createFromNib()
I have use the command listed below in the recent past and it seems to work fine.
ActiveWorkbook.RefreshAll
Hope that helps.
Use Addforce() method of a rigidbody compenent, make sure rigidbody is attached to the object and gravity is enabled, something like this
gameObj.rigidbody2D.AddForce(Vector3.up * 10 * Time.deltaTime); or
gameObj.rigidbody2D.AddForce(Vector3.up * 1000);
See which combination and what values matches your requirement and use accordingly. Hope it helps
DESCRIBE all_tab_columns
will show a TABLE_NAME VARCHAR2(30)
Note VARCHAR2(30) means a 30 byte limitation, not a 30 character limitation, and therefore may be different if your database is configured/setup to use a multibyte character set.

You have to tell replace() to repeat the regex:
.replace(/ /g,'')
The g character makes it a "global" match, meaning it repeats the search through the entire string. Read about this, and other RegEx modifiers available in JavaScript here.
If you want to match all whitespace, and not just the literal space character, use \s
instead:
.replace(/\s/g,'')
You can also use .replaceAll
if you're using a sufficiently recent version of JavaScript, but there's not really any reason to for your specific use case, since catching all whitespace requires a regex, and when using a regex with .replaceAll
, it must be global, so you just end up with extra typing:
.replaceAll(/\s/g,'')
I use something similar to what posit labs does. Save the console in a closure and you have it all in one portable function.
var GlobalDebug = (function () {
var savedConsole = console;
return function(debugOn,suppressAll){
var suppress = suppressAll || false;
if (debugOn === false) {
console = {};
console.log = function () { };
if(suppress) {
console.info = function () { };
console.warn = function () { };
console.error = function () { };
} else {
console.info = savedConsole.info;
console.warn = savedConsole.warn;
console.error = savedConsole.error;
}
} else {
console = savedConsole;
}
}
})();
Just do globalDebug(false) to toggle log messages off or globalDebug(false,true) to remove all console messages.
JPanel jPanel = new JPanel();
jPanel.setBorder(BorderFactory.createLineBorder(Color.black));
Here not only jPanel, you can add border to any Jcomponent
a.button a:hover
means "a link that's being hovered over that is a child of a link with the class button
".
Go instead for a.button:hover

It looks to me, like you're working in windows in which case a new line character in not simply \n
but rather \r\n
You can always get the correct new line character through System.getProperty("line.separator")
for example.
Because we make UI into XML but view objects is what we display so we somehow need to convert xml into view objects so inflating means we are converting xml into view objects so that it can be displayed, for this we need a service called layout inflator service and give it an xml and it will be convert for you.
I had the same problem... my problem was that I was closing my quartz window after plot(x,y). Once I kept it open, the lines that previously resulted in errors just added things to my plot (like they were supposed to). Hopefully this might help some people who arrive at this page.
It's used to add padding in UIScrollView
Without contentInset
, a table view is like this:
Then set contentInset
:
tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)
The effect is as below:
Seems to be better, right?
And I write a blog to study the contentInset
, criticism is welcome.
Assuming your ints are 0, 375, 668,5 and 6:
{
"Id": "610",
"Name": "15",
"Description": "1.99",
"ItemModList": [
0,
375,
668,
5,
6
]
}
I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/
Convert the Special characters to apostrophe,
Data <- gsub("[^0-9A-Za-z///' ]","'" , Data ,ignore.case = TRUE)
Below code it to remove extra ''' apostrophe
Data <- gsub("''","" , Data ,ignore.case = TRUE)
Use gsub(..)
function for replacing the special character with apostrophe
What you want to do is use the HTML5 attribute placeholder
which lets you set a default value for your input box:
<input type="text" name="inputBox" placeholder="enter your text here">
This should achieve what you're looking for. However, be careful because the placeholder attribute is not supported in Internet Explorer 9 and earlier versions.
Normally, Visual Studio creates it automatically if you add three single comment-markers above the thing you like to comment (method, class).
In C# this would be ///
.
If Visual Studio doesn't do this, you can enable it in
Options->Text Editor->C#->Advanced
and check
Generate XML documentation comments for ///
Note: The results below apply to older versions of iOS, but when testing on iOS 13 the stepping doesn't occur. I don't know for which version of iOS the stepping was removed.
When using CAGradientLayer
, as opposed to CGGradient
, the gradient is not smooth, but has noticeable stepping to it. See :
To get more attractive results it is better to use CGGradient
.
It doesn't work in generality. Not all valid dict keys make addressable attributes ("the key"). So, you'll need to be careful.
Python objects are all basically dictionaries. So I doubt there is much performance or other penalty.
You can center a button
without using text-align
on the parent div

To complement Jon Lin's answer, here is a no-trailing-slash technique that also works if the website is located in a directory (like example.org/blog/):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]
For the sake of completeness, here is an alternative emphasizing that REQUEST_URI
starts with a slash (at least in .htaccess
files):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /(.*)/$
RewriteRule ^ /%1 [R=301,L] <-- added slash here too, don't forget it
Just don't use %{REQUEST_URI} (.*)/$
. Because in the root directory REQUEST_URI
equals /
, the leading slash, and it would be misinterpreted as a trailing slash.

I would not use Group as column name since it is reserved word. However following SQL would work.
SELECT a.Person, a.Group, a.Age FROM [TABLE_NAME] a
INNER JOIN
(
SELECT `Group`, MAX(Age) AS oldest FROM [TABLE_NAME]
GROUP BY `Group`
) b ON a.Group = b.Group AND a.Age = b.oldest
In order to get the desired result, you must set "box-sizing: border-box" vs. the default which is "box-sizing: content-box". This is precisely the issue you are referring to (From MDN):
This is the initial and default value as specified by the CSS standard. The width and height properties are measured including only the content, but not the padding, border or margin.
The width and height properties include the content, the padding and border, but not the margin."
Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/box-sizing
Compatibility for this CSS is good.
At the time of writing this answer, there was no method to embed which let the user navigate inside folders and view the files without her leaving the website (the method in other answers, makes everything open in a new tab on google drive website), so I made my own tool for it. To embed a drive, paste the iframe code below in your HTML:
<iframe src="https://googledriveembedder.collegefam.com/?key=YOUR_API_KEY&folderid=FOLDER_ID_WHIHCH_IS_PUBLICLY_VIEWABLE" style="border:none;" width="100%"></iframe>
In the above code, you need to have your own API key and the folder ID. You can set the height as per your wish.
To get the API key:
1.) Go to https://console.developers.google.com/ Create a new project.
2.) From the menu button, go to 'APIs and Services' --> 'Dashboard' --> Click on 'Enable APIs and Services'.
3.) Search for 'Google Drive API', enable it. Then go to "credentials' tab, and create credentials. Keep your API key unrestricted.
4.) Copy the newly generated API key.
To get the folder ID:
1.)Go to the google drive folder you want to embed (for example, drive.google.com/drive/u/0/folders/1v7cGug_e3lNT0YjhvtYrwKV7dGY-Nyh5u [this is not a real folder]) Ensure that the folder is publicly shared and visible to anyone.
2.) Copy the part after 'folders/', this is your folder ID.
Now put both the API key and folder id in the above code and embed.
Note: To hide the download button for files, add '&allowdl=no' at the end of the iframe's src URL.
I made the widget keeping mobile users in mind, however it suits both mobile and desktop. If you run into issues, leave a comment here. I have attached some screenshots of the content of the iframe here.
The following worked for me: https://github.com/microsoft/TypeScript/issues/28631#issuecomment-472606019 I fix it by doing something like this:
const Component = (isFoo ? FooComponent : BarComponent) as React.ElementType
That depends on how the fragment is structured. If you can have some of the methods on the Fragment Class B static and also the target TextView object static, you can call the method directly on Fragment Class A. This is better than a listener as the method is performed instantaneously, and we don't need to have an additional task that performs listening throughout the activity. See example below:
Fragment_class_B.setmyText(String yourstring);
On Fragment B you can have the method defined as:
public static void setmyText(final String string) {
myTextView.setText(string);
}
Just don't forget to have myTextView set as static on Fragment B, and properly import the Fragment B class on Fragment A.
Just did the procedure on my project recently and it worked. Hope that helped.
Bash is a Command Line Interface that was created over twenty-seven years ago by Brian Fox as a free software replacement for the Bourne Shell. A shell is a specific kind of Command Line Interface. Bash is "open source" which means that anyone can read the code and suggest changes. Since its beginning, it has been supported by a large community of engineers who have worked to make it an incredible tool. Bash is the default shell for Linux and Mac. For these reasons, Bash is the most used and widely distributed shell.
Windows has a different Command Line Interface, called Command Prompt. While this has many of the same features as Bash, Bash is much more popular. Because of the strength of the open source community and the tools they provide, mastering Bash is a better investment than mastering Command Prompt.
To use Bash on a Windows computer, we need to download and install a program called Git Bash. Git Bash (Is the Bash for windows) allows us to easily access Bash as well as another tool called Git, inside the Windows environment.
I have used this:

Just Call super.variable in sub class constructor
public abstract class Beverage {
int cost;
int getCost() {
return cost;
}
}`
public class Coffee extends Beverage {
int cost = 10;
Coffee(){
super.cost = cost;
}
}`
public class Driver {
public static void main(String[] args) {
Beverage coffee = new Coffee();
System.out.println(coffee.getCost());
}
}
Output is 10.
This is happening because your PHP code is getting executed before the form gets posted.
To avoid this wrap your PHP code in following if statement and it will handle the rest no need to set if statements for each variables
if(isset($_POST) && array_key_exists('name_of_your_submit_input',$_POST))
{
//process PHP Code
}
else
{
//do nothing

(npm install express
while in the project's root directory)
Your project depends on both express
and ejs
, so you should list them both as dependencies in your package.json
.
That way when you run npm install
in you project directory, it'll install both express
and ejs
, so that var express = require('express')
will be the local installation of express (which knows about the ejs
module that you installed locally) rather than the global one, which doesn't.
In general it's a good idea to explicitly list all dependencies in your package.json
even though some of them might already be globally installed, so you don't have these types of issues.

It's your "fault" in that that's how Or
is defined, so it's the behaviour you should expect:
In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.
But you don't have to endure it. You can use OrElse
to get short-circuiting behaviour.
So you probably want:
If (example Is Nothing OrElse Not example.Item = compare.Item) Then
'Proceed
End If
I can't say it reads terribly nicely, but it should work...
Java is a statically typed language, so the compiler does most of this checking for you. Once you declare a variable to be a certain type, the compiler will ensure that it is only ever assigned values of that type (or values that are sub-types of that type).
The examples you gave (int
, array, double
) these are all primitives, and there are no sub-types of them. Thus, if you declare a variable to be an int
:
int x;
You can be sure it will only ever hold int
values.
If you declared a variable to be a List
, however, it is possible that the variable will hold sub-types of List
. Examples of these include ArrayList
, LinkedList
, etc.
If you did have a List
variable, and you needed to know if it was an ArrayList
, you could do the following:
List y;
...
if (y instanceof ArrayList) {
...its and ArrayList...
}
However, if you find yourself thinking you need to do that, you may want to rethink your approach. In most cases, if you follow object-oriented principles, you will not need to do this. There are, of course, exceptions to every rule, though.
you can use OnClick="document.getElementById('formID_NOT_NAME').SUBMIT()"

To create a Java project: create a new project directory, jump into it and execute
gradle init --type java-library
Source folders and a Gradle build file (including a wrapper) will be build.
One solution that has worked for me is adding the style white-space: normal;
to the textarea because at times it is not feasible to eliminate all the whitespace (for example when you want your code to abide to your coding guidelines which requires adding tabs, whitespaces and line breaks)
Please note that the default for textarea, at least in chrome is:
white-space: pre-wrap;
An alternative way to (not dynamically) link a text to activate a worksheet without macros is to make the selected string an actual link. You can do this by selecting the cell that contains the text and press CTRL+K then select the option/tab 'Place in this document' and select the tab you want to activate. If you would click the text (that is now a link) the configured sheet will become active/selected.
2^8 = 256 Characters. A character in binary is a series of 8 ( 0 or 1).

Try this:
response.write(JSON.stringify(request.body));
That will take the object which bodyParser
has created for you and turn it back into a string and write it to the response. If you want the exact request body (with the same whitespace, etc), you will need data
and end
listeners attached to the request before and build up the string chunk by chunk as you can see in the json parsing source code from connect.
Clearly you aren't sending the data with ObjectOutputStream:
you are just writing the bytes.
readObject()
you must write with writeObject().
readUTF()
you must write with writeUTF().
readXXX()
you must write with writeXXX(),
for most values of XXX.If you are working with xamarin, you can put this code
WindowSoftInputMode =Android.Views.SoftInput.AdjustPan | Android.Views.SoftInput.AdjustResize
in activity attribute of the MainActivity class.
For example, now the activity attribute will look like below
[Activity(WindowSoftInputMode =Android.Views.SoftInput.AdjustPan | Android.Views.SoftInput.AdjustResize)]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
{
//some code here.
}
Just in case if you are using Telerik components and you have a reference in your javascript with <%= .... %> then wrap your script tag with a RadScriptBlock.
<telerik:RadScriptBlock ID="radSript1" runat="server">
<script type="text/javascript">
//Your javascript
</script>
</telerik>

The error may occur if the NodeJs
is installed incorrectly or not installed at all.
The proper way to fix that is to install/reinstall it the right way (check their official website for that), but if you're searching for a quick solution, you can try to install Angular CLI globally:
npm install -g @angular/cli
If it doesn't work and you are in a hurry, use sudo
:
sudo npm install -g @angular/cli
Don't forget to reopen your terminal window.
If you take a look at the following example - it uses fixed width columns, and I think this is the behavior requested.

If the bottom example is the same as the top, you don't need the jquery column plugin.

You Can simply Use One Jsp Page To accomplish the task.
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.sql.*"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<%
String username=request.getParameter("user_name");
String password=request.getParameter("password");
String role=request.getParameter("role");
try
{
Class.forName("com.mysql.jdbc.Driver");
Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/t_fleet","root","root");
Statement st=con.createStatement();
String query="select * from tbl_login where user_name='"+username+"' and password='"+password+"' and role='"+role+"'";
ResultSet rs=st.executeQuery(query);
while(rs.next())
{
session.setAttribute( "user_name",rs.getString(2));
session.setMaxInactiveInterval(3000);
response.sendRedirect("homepage.jsp");
}
%>
<%}
catch(Exception e)
{
out.println(e);
}
%>
</body>
I have use username, password and role to get into the system. One more thing to implement is you can do page permission checking through jsp and javascript function.
I found to delete this section from the project file fix the problem.

Late answer, and there are many good answers already.
In case you want a simple script to check if the maximum file watches is big enough, and if not, increase the limit, here it is:
#!/usr/bin/env bash
let current_watches=`sysctl -n fs.inotify.max_user_watches`
if (( current_watches < 80000 ))
then
echo "Current max_user_watches ${current_watches} is less than 80000."
else
echo "Current max_user_watches ${current_watches} is already equal to or greater than 80000."
exit 0
fi
if sudo sysctl -w fs.inotify.max_user_watches=80000 && sudo sysctl -p && echo fs.inotify.max_user_watches=80000 | sudo tee /etc/sysctl.d/10-user-watches.conf
then
echo "max_user_watches changed to 80000."
else
echo "Could not change max_user_watches."
exit 1
fi
The script increases the limit to 80000
, but feel free to set a limit that you want.
Your problem has nothing to do with encodings, it's a simple matter of understanding basic C++. You are returning a pointer to a local variable from your function, which will have gone out of scope by the time anyone can use it, thus creating undefined behaviour (i.e. a programming error).
Follow this Golden Rule: "If you are using naked char pointers, you're Doing It Wrong. (Except for when you aren't.)"
I've previously posted some code to do the conversion and communicating the input and output in C++ std::string
and std::wstring
objects.
for Win10 need move your key to user's home dir for linuxlike os you need to chmod to 700 like or 600 etc.
