Some things to know about graphviz:
Example:
# Just in case, try the default...
path = r"C:\Program Files (x86)\Graphviz2.38\bin"
String element = "el5";
int x = element.charAt(2) - 48;
Subtracting ascii value of '0' = 48 from char
var a = document.getElementById('yourlinkId'); //or grab it by tagname etc
a.href = "somelink url"
There is also the InStrRev function which does the same type of thing, but starts searching from the end of the text to the beginning.
Per @rene's answer...
Dim pos As Integer
pos = InStrRev("find the comma, in the string", ",")
...would still return 15 to pos, but if the string has more than one of the search string, like the word "the", then:
Dim pos As Integer
pos = InStrRev("find the comma, in the string", "the")
...would return 20 to pos, instead of 6.
if(myVar) { code }
will be NOT executed only when myVar
is equal to: false, 0, "", null, undefined, NaN
or you never defined variable myVar
(then additionally code stop execution and throw exception).if(myVar !== null) {code}
will be NOT executed only when myVar
is equal to null
or you never defined it (throws exception).Here you have all (src)
if
== (its negation !=)
=== (its negation !==)
With the excellent matplotlib
and numpy
packages
from matplotlib import pyplot as mp
import numpy as np
def gaussian(x, mu, sig):
return np.exp(-np.power(x - mu, 2.) / (2 * np.power(sig, 2.)))
x_values = np.linspace(-3, 3, 120)
for mu, sig in [(-1, 1), (0, 2), (2, 3)]:
mp.plot(x_values, gaussian(x_values, mu, sig))
mp.show()
You're close.
std::list<Student>::iterator it;
for (it = data.begin(); it != data.end(); ++it){
std::cout << it->name;
}
Note that you can define it
inside the for
loop:
for (std::list<Student>::iterator it = data.begin(); it != data.end(); ++it){
std::cout << it->name;
}
And if you are using C++11 then you can use a range-based for
loop instead:
for (auto const& i : data) {
std::cout << i.name;
}
Here auto
automatically deduces the correct type. You could have written Student const& i
instead.
for(var memberName in ad)
{
//Member Name: memberName
//Member Value: ad[memberName]
}
Member means Member property, member variable, whatever you want to call it >_>
The above code will return EVERYTHING, including toString... If you only want to see if the object's prototype has been extended:
var dummyObj = {};
for(var memberName in ad)
{
if(typeof(dummyObj[memberName]) == typeof(ad[memberName])) continue; //note A
//Member Name: memberName
//Member Value: ad[memberName]
}
Note A: We check to see if the dummy object's member has the same type as our testing object's member. If it is an extend, dummyobject's member type should be "undefined"
So to make your expression work, changing &&
for -a
will do the trick.
It is correct like this:
if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
then ....
or like
if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
then ....
or even
if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
then ....

You fixed the push, but, independently of that push issue (which I explained in "Why do I need to explicitly push a new branch?": git push -u origin master
or git push -u origin --all
), you need now to resolve the authentication issue.
That depends on your url (ssh as in '[email protected]/yourRepo
, or https as in https://github.com/You/YourRepo
)
For https url:
If your account is protected by the two-factor authentication, your regular password won't work (for https url), as explained here or here.
Same problem if your password contains special character (as in this answer)
If https doesn't work (because you don't want to generate a secondary key, a PAT: personal Access Token), then you can switch to ssh, as I have shown here.
As noted by qwerty in the comments, you can automatically create the branch of same name on the remote with:
git push -u origin head
Why?
.git\HEAD
file) has the refspec of the currently checked out branch (for example: ref: refs/heads/master
)Since the refpec used for this push is head: (no destination), a missing :<dst>
means to update the same ref as the <src>
(head, which is a branch).
That won't work if HEAD is detached though.
You forgot to put z as an bind variable.
The following EXECUTE command runs a PL/SQL statement that references a stored procedure:
SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')
Note that the value returned by the stored procedure is being return into :Z
Migration files must match the pattern *_*.php
, or else they won't be found. Since users.php
does not match this pattern (it has no underscore), this file will not be found by the migrator.
Ideally, you should be creating your migration files using artisan:
php artisan make:migration create_users_table
This will create the file with the appropriate name, which you can then edit to flesh out your migration. The name will also include the timestamp, to help the migrator determine the order of migrations.
You can also use the --create
or --table
switches to add a little bit more boilerplate to help get you started:
php artisan make:migration create_users_table --create=users
The documentation on migrations can be found here.
Best way you use CommandLineRunner or ApplicationRunner The only difference between is run() method CommandLineRunner accepts array of string and ApplicationRunner accepts ApplicationArugument.
(Not everyone likes doing things through the git command line interface)
Once this has been set up, you only need to do steps 7-13 from then on.
Fetch > checkout master branch > reset to their master > Push changes to server
Double click on your "master" branch to check it out if it is not checked out already.
Find the commit that you want to reset to, if you called the repo "master" you will most likely want to find the commit with the "master/master" tag on it.
Right click on the commit > "Reset current branch to this commit".
In the dialog, set the "Using mode:" field to "Hard - discard all working copy changes" then press "OK" (make sure to put any changes that you don't want to lose onto a separate branch first).
Your Done!
I know exactly what you mean. The same thing in Swift will be no problem. The bottom line is use let
, not var
.
The fact that primitives are passed by value, but the fact that the value of var i
at the point of iteration is not copied into the anonymous function is quite surprising to say the least.
for (let i = 0; i < boxArray.length; i++) {
boxArray[i].onclick = function() { console.log(i) }; // Correctly prints the index
}

If you are in the context of a Faraday request, you can also just pass the params hash as the second argument and faraday takes care of making proper param URL part out of it:
faraday_instance.get(url, params_hsh)
In order to generate key hash you need to follow some easy steps.
1) Download Openssl from: here.
2) Make a openssl folder in C drive
3) Extract Zip files into this openssl folder created in C Drive.
4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)
5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin).
6) Copy the following code and hit enter
keytool -exportcert -alias androiddebugkey -keystore debug.keystore > c:\openssl\bin\debug.txt
7) Now you need to enter password, Password = android.
8) If you see in openssl Bin folder, you will get a file with the name of debug.txt
9) Now either you can restart command prompt or work with existing command prompt
10) get back to C drive and give the path of openssl Bin folder
11) copy the following code and paste
openssl sha1 -binary debug.txt > debug_sha.txt
12) you will get debug_sha.txt in openssl bin folder
13) Again copy following code and paste
openssl base64 -in debug_sha.txt > debug_base64.txt
14) you will get debug_base64.txt in openssl bin folder
15) open debug_base64.txt file Here is your Key hash.
just to pull the master without checking out the master I use
git fetch origin master:master
Props down, events up. That's Vue's Pattern. The point is that if you try to mutate props passing from a parent. It won't work and it just gets overwritten repeatedly by the parent component. Child component can only emit an event to notify parent component to do sth. If you don't like these restrict, you can use VUEX(actually this pattern will suck in complex components structure, you should use VUEX!)
The error message will include the name of the constraint that was violated (there may be more than one unique constraint on a table). You can use that constraint name to identify the column(s) that the unique constraint is declared on
SELECT column_name, position
FROM all_cons_columns
WHERE constraint_name = <<name of constraint from the error message>>
AND owner = <<owner of the table>>
AND table_name = <<name of the table>>
Once you know what column(s) are affected, you can compare the data you're trying to INSERT
or UPDATE
against the data already in the table to determine why the constraint is being violated.
You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:
render: function() {
return (
<span>
// This will go through all the elements in arrayFromJson and
// render each one as a <SomeComponent /> with data from the object
{this.state.arrayFromJson.map(function(object) {
return (
<SomeComponent key={object.id} data={object} />
);
})}
</span>
);
}
Summarizing 2 ways to replace strings:
group<-data.frame(group=c("12357e", "12575e", "197e18", "e18947"))
1) Use gsub
group$group.no.e <- gsub("e", "", group$group)
2) Use the stringr
package
group$group.no.e <- str_replace_all(group$group, "e", "")
Both will produce the desire output:
group group.no.e
1 12357e 12357
2 12575e 12575
3 197e18 19718
4 e18947 18947
Unset($array[0]);
Sort($array);
I don't know why this is being downvoted, but if anyone has bothered to try it, you will notice that it works.
Using sort on an array reassigns the keys of the the array. The only drawback is it sorts the values.
Since the keys will obviously be reassigned, even with array_values
, it does not matter is the values are being sorted or not.
The default border-style
is none
, so you must specify that as well as the width and the colour.
You can use the border
shorthand property to set all three values in one go.
Also, the border attribute describes the border for the table and the cells. CSS is much more flexible so it only describes the border of the elements you are selecting. You need to select the cells too in order to get the same effect.
table, th, td {
border: solid black 1px;
}
See also border properties and tables in CSS.
Use the input()
built-in function to get a input line from the user.
You can read the help here.
You can use the following code to get several line at once (finishing by an empty one):

Use,
var url = $(this).attr('href');
window.open(url, '_blank');
Update:the href
is better off being retrieved with prop since it will return the full url and it's slightly faster.
var url = $(this).prop('href');
Here's a straightforward script for finding out the limit:
if (localStorage && !localStorage.getItem('size')) {
var i = 0;
try {
// Test up to 10 MB
for (i = 250; i <= 10000; i += 250) {
localStorage.setItem('test', new Array((i * 1024) + 1).join('a'));
}
} catch (e) {
localStorage.removeItem('test');
localStorage.setItem('size', i - 250);
}
}
Here's the gist, JSFiddle and blog post.
The script will test setting increasingly larger strings of text until the browser throws and exception. At that point it’ll clear out the test data and set a size key in localStorage storing the size in kilobytes.
Adding to @Laurens Holsts answer. This is 50% compressed.
function shuffleArray(d) {
for (var c = d.length - 1; c > 0; c--) {
var b = Math.floor(Math.random() * (c + 1));
var a = d[c];
d[c] = d[b];
d[b] = a;
}
return d
};
Swift 4.1 and 5. We use queues in many places in our code. So, I created Threads class with all queues. If you don't want to use Threads class you can copy the desired queue code from class methods.
class Threads {
static let concurrentQueue = DispatchQueue(label: "AppNameConcurrentQueue", attributes: .concurrent)
static let serialQueue = DispatchQueue(label: "AppNameSerialQueue")
// Main Queue
class func performTaskInMainQueue(task: @escaping ()->()) {
DispatchQueue.main.async {
task()
}
}
// Background Queue
class func performTaskInBackground(task:@escaping () throws -> ()) {
DispatchQueue.global(qos: .background).async {
do {
try task()
} catch let error as NSError {
print("error in background thread:\(error.localizedDescription)")
}
}
}
// Concurrent Queue
class func perfromTaskInConcurrentQueue(task:@escaping () throws -> ()) {
concurrentQueue.async {
do {
try task()
} catch let error as NSError {
print("error in Concurrent Queue:\(error.localizedDescription)")
}
}
}
// Serial Queue
class func perfromTaskInSerialQueue(task:@escaping () throws -> ()) {
serialQueue.async {
do {
try task()
} catch let error as NSError {
print("error in Serial Queue:\(error.localizedDescription)")
}
}
}
// Perform task afterDelay
class func performTaskAfterDealy(_ timeInteval: TimeInterval, _ task:@escaping () -> ()) {
DispatchQueue.main.asyncAfter(deadline: (.now() + timeInteval)) {
task()
}
}
}
Example showing the use of main queue.
override func viewDidLoad() {
super.viewDidLoad()
Threads.performTaskInMainQueue {
//Update UI
}
}
Well simple enough, I got it in a one liner (bash)
git branch | sed -n '/\* /s///p'

And while I am there, the one liner to get the remote tracking branch (if any)
git rev-parse --symbolic-full-name --abbrev-ref @{u}
You can use the below formula to find the distance between the 2 points:
distance*distance = ((x2 - x1)*(x2 - x1)) + ((y2 - y1)*(y2 - y1))
For the links which contains common url have to console in a variable. Then attempt it sequentially.
webelements allLinks=driver.findelements(By.xpath("//a[contains(@href,'http://122.11.38.214/dl/appdl/application/apk')]"));
int linkCount=allLinks.length();
for(int i=0; <linkCount;i++)
{
driver.findelement(allLinks[i]).click();
}
This may help you find what you're looking for... Batch script loop
My answer is as follows:
@echo off
:start
set /a var+=1
if %var% EQU 100 goto end
:: Code you want to run goes here
goto start
:end
echo var has reached %var%.
pause
exit
The first set of commands under the start label loops until a variable, %var% reaches 100. Once this happens it will notify you and allow you to exit. This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file's path (Shift+Right Click on file and select "Copy as Path") where the comment is placed.
With ES2015 support it can be done by:
foo.sort((a, b) => a.updated_at < b.updated_at ? -1 : 1)
Using sshpass works best. To just include your password in scp use the ' ':
scp user1:'password'@xxx.xxx.x.5:sys_config /var/www/dev/
If you are a slacker like me you might like to use the File::Slurp module. The read_dir function will reads directory contents into an array, removes the dots, and if needed prefix the files returned with the dir for absolute paths
my @paths = read_dir( '/path/to/dir', prefix => 1 ) ;
If you're just gonna click the button when Enter was pressed how about this?

{
buttonSearch.PerformClick();
}
'Greedy' means match longest possible string.
'Lazy' means match shortest possible string.
For example, the greedy h.+l
matches 'hell'
in 'hello'
but the lazy h.+?l
matches 'hel'
.
Example 1:
0 means ignore
1 means show
User.find({}, { createdAt: 0, updatedAt: 0, isActive: 0, _id : 1 }).then(...)
Example 2:
User.findById(id).select("_id, isActive").then(...)
in sed you can reference groups in your pattern with "\1", "\2", .... so if the pattern you're looking for is "PATTERN", and you want to insert "BEFORE" in front of it, you can use, sans escaping
sed 's/(PATTERN)/BEFORE\1/g'
i.e.
sed 's/\(PATTERN\)/BEFORE\1/g'
If jQuery UI datepicker isn't working but it used to work on similar DOM earlier, try removing all the classes and try binding it to just a simple input with its id. In my case a class was interfering with it and preventing the date picker to appear.
Set the CheckBox
as focusable="false"
in your XML layout. Otherwise it will steal click events from the list view.
Of course, if you do this, you need to manually handle marking the CheckBox
as checked/unchecked if the list item is clicked instead of the CheckBox
, but you probably want that anyway.
It's a named export vs a default export. export const
is a named export that exports a const declaration or declarations.
To emphasize: what matters here is the export
keyword as const
is used to declare a const declaration or declarations. export
may also be applied to other declarations such as class or function declarations.
Default Export (export default
)
You can have one default export per file. When you import you have to specify a name and import like so:
import MyDefaultExport from "./MyFileWithADefaultExport";
You can give this any name you like.
Named Export (export
)
With named exports, you can have multiple named exports per file. Then import the specific exports you want surrounded in braces:
// ex. importing multiple exports:
import { MyClass, MyOtherClass } from "./MyClass";
// ex. giving a named import a different name by using "as":
import { MyClass2 as MyClass2Alias } from "./MyClass2";
// use MyClass, MyOtherClass, and MyClass2Alias here
Or it's possible to use a default along with named imports in the same statement:
import MyDefaultExport, { MyClass, MyOtherClass} from "./MyClass";
Namespace Import
It's also possible to import everything from the file on an object:
import * as MyClasses from "./MyClass";
// use MyClasses.MyClass, MyClasses.MyOtherClass and MyClasses.default here
Notes
A default export is actually a named export with the name default
so you are able to import it with a named import:
import { default as MyDefaultExport } from "./MyFileWithADefaultExport";

This is much like a previous example above. I found when trying to implement that example that if the table row to be expanded was clicked while it was not expanded it would disappear, and it would no longer be expandable
To fix that I simply removed the ability to click the expandable element for slide up and made it so that you can only toggle using the above table row.
I also made some minor changes to HTML and corresponding jQuery.
NOTE: I would have just made a comment but am not allowed to yet therefore the long post. Just wanted to post this as it took me a bit to figure out what was happening to the disappearing table row.

I have the following in my .bash_profile:
function mark {
export $1=`pwd`;
}
so anytime I want to remember a directory, I can just type, e.g. mark there .
Then when I want to go back to that location, I just type cd $there

On textarea resizing in webkit based browsers:
Setting max-height and max-width on the textarea will not remove the visual resize handle. Try:
resize: none;
(and yes I agree with "try to avoid doing anything which breaks the user's expectation", but sometimes it does make sense, i.e. in the context of a web application)
To customize the look and feel of webkit form elements from scratch:
-webkit-appearance: none;
Based on the official documentation:
dummies = pd.get_dummies(df['Category']).rename(columns=lambda x: 'Category_' + str(x))
df = pd.concat([df, dummies], axis=1)
df = df.drop(['Category'], inplace=True, axis=1)
There is also a nice post in the FastML blog.
Setting background size does not help, the following solution worked for me:
.class {
background-image: url(blablabla.jpg);
/* Add this */
height: auto;
}
It basically crops the image and makes it fit in, background-size: contain/cover
still didn't make it fit.
Well, just do this and your problem is solved :
document.getElementById('buttonLED'+id).setAttribute('onclick','writeLED(1,1)')

Since the last update of the xmlhttprequest module was around 2 years ago, in some cases it does not work as expected.
So instead, you can use the xhr2 module. In other words:
var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();
becomes:
var XMLHttpRequest = require('xhr2');
var xhr = new XMLHttpRequest();
But ... of course, there are more popular modules like Axios, because -for example- uses promises:
// Make a request for a user with a given ID
axios.get('/user?ID=12345').then(function (response) {
console.log(response);
}).catch(function (error) {
console.log(error);
});
Use this to execute *.sql files when the PostgreSQL server is located in a difference place:
psql -h localhost -d userstoreis -U admin -p 5432 -a -q -f /home/jobs/Desktop/resources/postgresql.sql
-h PostgreSQL server IP address
-d database name
-U user name
-p port which PostgreSQL server is listening on
-f path to SQL script
-a all echo
-q quiet
Then you are prompted to enter the password of the user.

Hey friends I got the solution of above problem without using Gson
library. Here I post source code.
1.Variable declaration i.e
SharedPreferences shared;
ArrayList<String> arrPackage;
2.Variable initialization i.e
shared = getSharedPreferences("App_settings", MODE_PRIVATE);
// add values for your ArrayList any where...
arrPackage = new ArrayList<>();
3.Store value to sharedPreference using packagesharedPreferences()
:
private void packagesharedPreferences() {
SharedPreferences.Editor editor = shared.edit();
Set<String> set = new HashSet<String>();
set.addAll(arrPackage);
editor.putStringSet("DATE_LIST", set);
editor.apply();
Log.d("storesharedPreferences",""+set);
}
4.Retrive value of sharedPreference using retriveSharedValue()
:
private void retriveSharedValue() {
Set<String> set = shared.getStringSet("DATE_LIST", null);
arrPackage.addAll(set);
Log.d("retrivesharedPreferences",""+set);
}
I hope it will helpful for you...
Spring Boot provide the plugin with maven.
So you can go to your project directory and run
mvn spring-boot:run
This command line run will be easily when you're using spring-boot-devs-tool with auto reload/restart when you have changed you application.
If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:
Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);
Hope it helps.

--debug --stacktrace -a, --no-rebuild -q, --quiet --offline
You can simply do:
"123456".Select(q => new string(q,1)).ToArray();
to have an enumerable of integers, as per comment request, you can:
"123456".Select(q => int.Parse(new string(q,1))).ToArray();
It is a little weak since it assumes the string actually contains numbers.
It is just this:
if 'errormessage' in kwargs:
print("yeah it's here")
You need to check, if the key is in the dictionary. The syntax for that is some_key in some_dict
(where some_key
is something hashable, not necessarily a string).
The ideas you have linked (these ideas) contained examples for checking if specific key existed in dictionaries returned by locals()
and globals()
. Your example is similar, because you are checking existence of specific key in kwargs
dictionary (the dictionary containing keyword arguments).
If you use RequestDispatcher.forward()
to route the request from controller to the view, then request URI is exposed as a request attribute named javax.servlet.forward.request_uri
. So, you can use
request.getAttribute("javax.servlet.forward.request_uri")
or
${requestScope['javax.servlet.forward.request_uri']}
Based on the syntax I'm assuming that it is some language which is descendant of C. As per what I have seen, length
is used for simple collection items like arrays and in most cases it is a property.
size()
is a function and is used for dynamic collection objects. However for all the purposes of using, you wont find any differences in outcome using either of them. In most implementations, size simply returns length property.
You could use moment.js with Postman to give you that timestamp format.
You can add this to the pre-request script:
const moment = require('moment');
pm.globals.set("today", moment().format("MM/DD/YYYY"));
Then reference {{today}}
where ever you need it.
If you add this to the Collection Level Pre-request Script
, it will be run for each request in the Collection
. Rather than needing to add it to all the requests individually.
For more information about using moment
in Postman, I wrote a short blog post: https://dannydainton.com/2018/05/21/hold-on-wait-a-moment/
The correct Angular way to do this is to write a single page app, AJAX in the form template, then populate it dynamically from the model. The model is not populated from the form by default because the model is the single source of truth. Instead Angular will go the other way and try to populate the form from the model.
If you have an app written, this might involve some fairly hefty architectural changes. If you're trying to use Angular to enhance an existing form, rather than constructing an entire single page app from scratch, you can pull the value from the form and store it in the scope at link time using a directive. Angular will then bind the value in the scope back to the form and keep it in sync.
You can use a relatively simple directive to pull the value from the form and load it in to the current scope. Here I've defined an initFromForm directive.
var myApp = angular.module("myApp", ['initFromForm']);
angular.module('initFromForm', [])
.directive("initFromForm", function ($parse) {
return {
link: function (scope, element, attrs) {
var attr = attrs.initFromForm || attrs.ngModel || element.attrs('name'),
val = attrs.value;
if (attrs.type === "number") {val = parseInt(val)}
$parse(attr).assign(scope, val);
}
};
});
You can see I've defined a couple of fallbacks to get a model name. You can use this directive in conjunction with the ngModel directive, or bind to something other than $scope if you prefer.
Use it like this:
<input name="test" ng-model="toaster.test" value="hello" init-from-form />
{{toaster.test}}
Note this will also work with textareas, and select dropdowns.
<textarea name="test" ng-model="toaster.test" init-from-form>hello</textarea>
{{toaster.test}}
You typically set the port at the server using the rmiregistry command. You can set the port on the command line, or it will default to 1099
I think it's well explained here -- quoting just the key sentences of the long article:
The general concept behind a token-based authentication system is simple. Allow users to enter their username and password in order to obtain a token which allows them to fetch a specific resource - without using their username and password. Once their token has been obtained, the user can offer the token - which offers access to a specific resource for a time period - to the remote site.
In other words: add one level of indirection for authentication -- instead of having to authenticate with username and password for each protected resource, the user authenticates that way once (within a session of limited duration), obtains a time-limited token in return, and uses that token for further authentication during the session.
Advantages are many -- e.g., the user could pass the token, once they've obtained it, on to some other automated system which they're willing to trust for a limited time and a limited set of resources, but would not be willing to trust with their username and password (i.e., with every resource they're allowed to access, forevermore or at least until they change their password).
If anything is still unclear, please edit your question to clarify WHAT isn't 100% clear to you, and I'm sure we can help you further.

Compiled binaries of the PHP interpreter can be found at http://www.mamp.info/en/ downloads/index.html . Drop this downloaded folder into your /Applications/MAMP/bin/php! directory. Close and re-open your MAMP PRO application. Your new PHP version should now appear in the PHP drop down menu. MAMP PRO will only support PHP versions from the downloads page.
It should help you.

use [\\W+]
or "[^a-zA-Z0-9]"
as regex to match any special characters and also use String.replaceAll(regex, String) to replace the spl charecter with an empty string. remember as the first arg of String.replaceAll is a regex you have to escape it with a backslash to treat em as a literal charcter.
String c= "hjdg$h&jk8^i0ssh6";
Pattern pt = Pattern.compile("[^a-zA-Z0-9]");
Matcher match= pt.matcher(c);
while(match.find())
{
String s= match.group();
c=c.replaceAll("\\"+s, "");
}
System.out.println(c);
Open command prompt (cmd.exe/git bash)
Recommended:
npm install -g typescript@latest
or
yarn global add typescript@latest // if you use yarn package manager
This will install the latest typescript version if not already installed, otherwise it will update the current installation to the latest version.
And then verify which version is installed:
tsc -v
If you have typescript already installed you could also use the following command to update to latest version, but as commentators have reported and I confirm it that the following command does not update to latest (as of now [ Feb 10 '17
])!
npm update -g typescript@latest

For all who've opted for the if-else mesh solution, please use:
String columnName = metadata.getColumnName(
String displayName = metadata.getColumnLabel(i);
switch (metadata.getColumnType(i)) {
case Types.ARRAY:
obj.put(displayName, resultSet.getArray(columnName));
break;
...
Because in case of aliases in your query, the column name and column label are two different things. For example if you execute:
select col1, col2 as my_alias from table
You will get
[
{ "col1": 1, "col2": 2 },
{ "col1": 1, "col2": 2 }
]
Rather than:
[
{ "col1": 1, "my_alias": 2 },
{ "col1": 1, "my_alias": 2 }
]
attr("dominant-baseline", "central")
I went through every solution on this page, and fortunately @anatolii-pazhyn commented because his solution was the one that worked. Unfortunately I don't have enough reputation to upvote him, but I recommend trying his solution first:
git reset --hard origin/master
Which gave me:
HEAD is now at 900000b Comment from my last git commit here
I also recommend:
git rev-list origin..HEAD
# to see if the local repository is ahead, push needed
git rev-list HEAD..origin
# to see if the local repository is behind, pull needed
You can also use:
git rev-list --count --left-right origin/master...HEAD
# if you have numbers for both, then the two repositories have diverged
Best of luck
See the abc module. Basically, you define __metaclass__ = abc.ABCMeta
on the class, then decorate each abstract method with @abc.abstractmethod
. Classes derived from this class cannot then be instantiated unless all abstract methods have been overridden.
If your class is already using a metaclass, derive it from ABCMeta
rather than type
and you can continue to use your own metaclass.
A cheap alternative (and the best practice before the abc
module was introduced) would be to have all your abstract methods just raise an exception (NotImplementedError
is a good one) so that classes derived from it would have to override that method to be useful.
However, the abc
solution is better because it keeps such classes from being instantiated at all (i.e., it "fails faster"), and also because you can provide a default or base implementation of each method that can be reached using the super()
function in derived classes.
Testing this Javascript:
var arr = [1234563995.721, 12345691212.718, 1234568421.5891, 12345677093.49284];
var sum = 0;
for( var i = 0; i < arr.length; i++ ) {
sum += arr[i];
}
alert( "fMath(sum) = " + Math.round( sum * 1e12 ) / 1e12 );
alert( "fFixed(sum) = " + sum.toFixed( 5 ) );
Dont use Math.round( (## + ## + ... + ##) * 1e12) / 1e12
Instead, use ( ## + ## + ... + ##).toFixed(5) )
In IE 9, toFixed
works very well.
The open SPF wizard from the previous answer is no longer available, neither the one from Microsoft.
Transactional Annotations should be placed around all operations that are inseparable.
For example, your call is "change password". That consists of two operations
So in the above, if the audit fails, then should the password change also fail? If so, then the transaction should be around 1 and 2 (so at the service layer). If the email fails (probably should have some kind of fail safe on this so it won't fail) then should it roll back the change password and the audit?
These are the kind of questions you need to be asking when deciding where to put the @Transactional
.
I had such problem. In my case problem was in data - my column 'information' contained 1 unique value and it caused error
UPDATE: to correct work 'pivot' pairs (id_user,information) cannot have duplicates
It works:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],
'information':['phon','phon','phone','phone1','phone','phone1','phone'],
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')
it doesn't work:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],
'information':['phone','phone','phone','phone','phone','phone','phone'],
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')
For those using React, detecting a same-origin iframe load event is as simple as setting onLoad
event listener on iframe element.
<iframe src={'path-to-iframe-source'} onLoad={this.loadListener} frameBorder={0} />
You can simply add @HostBinding('class') class = 'someClass';
inside your @Component class.
Example:
@Component({
selector: 'body',
template: 'app-element'
})
export class App implements OnInit {
@HostBinding('class') class = 'someClass';
constructor() {}
ngOnInit() {}
}
If they all have the same extension (for example .jpg), you can use this:
for picture in *.jpg ; do
echo "the next file is $picture"
done
(This solution also works if the filename has spaces)
See my answer here if you're having this problem while running unit tests. Answer copied below:
Building upon Sébastien's answer, I added a pre-build step to my test project to automatically kill any
vstest.*
executables still running. The following pre-build command worked for me:taskkill /f /im vstest.* exit 0
The
exit 0
command is at the end to prevent build failure when there are novstest.*
executables running.
Here's a similar system for the situation where you have a variable you want to sort by, initially, but then you want to sort by a secondary variable according to the order that this secondary variable first appears in the initial sort.
In the function below, the initial sort variable is called order_by
and the secondary variable is called order_along
- as in "order by this variable along its initial order".

JUnit is part of Eclipse Java Development Tools (JDT). So, either install the JDT via Software Updates or download and install Eclipse IDE for Java Developers (actually, I'd recommend installing Eclipse IDE for Java EE Developers if you want a complete built-in environment for server side development).
You add it to a project by right clicking the project in the Package Explorer and selecting Build Path -> Add Libraries... Then simply select JUnit and click Next >.
I changed all space areas to  , just like that and it worked without problem.
val.replace(" ", " ");
I hope it helps someone.

Cross posting my answer from this SO question for another simple, pip version proof solution.
try: # for pip >= 10
from pip._internal.req import parse_requirements
from pip._internal.download import PipSession
except ImportError: # for pip <= 9.0.3
from pip.req import parse_requirements
from pip.download import PipSession
requirements = parse_requirements(os.path.join(os.path.dirname(__file__), 'requirements.txt'), session=PipSession())
if __name__ == '__main__':
setup(
...
install_requires=[str(requirement.req) for requirement in requirements],
...
)
Then just throw in all your requirements under requirements.txt
under project root directory.

jQuery Waypoints plugin goes very nice here.
$('.entry').waypoint(function() {

});
There are some examples on the site of the plugin.
If you want to return True
for an empty set, then I think it would be clearer to do:
return c == set()
i.e. "c
is equal to an empty set
".
(Or, for the other way around, return c != set()
).
In my opinion, this is more explicit (though less idiomatic) than relying on Python's interpretation of an empty set as False
in a boolean context.
I put all my startup scripts in a .bashrc.d directory. This is a common technique in such places as /etc/profile.d, etc.
while read file; do source "${file}"; done <<HERE
$(find ${HOME}/.bashrc.d -type f)
HERE
The problem with the solution using globbing...
for file in ${HOME}/.bashrc.d/*.sh; do source ${file};done
...is you might have a file list which is "too long". An approach like...
find ${HOME}/.bashrc.d -type f | while read file; do source ${file}; done
...runs but doesn't change the environment as desired.
Partial mocking using Mockito's spy method could be the solution to your problem, as already stated in the answers above. To some degree I agree that, for your concrete use case, it may be more appropriate to mock the DB lookup. From my experience this is not always possible - at least not without other workarounds - that I would consider as being very cumbersome or at least fragile. Note, that partial mocking does not work with ally versions of Mockito. You have use at least 1.8.0.
I would have just written a simple comment for the original question instead of posting this answer, but StackOverflow does not allow this.
Just one more thing: I really cannot understand that many times a question is being asked here gets comment with "Why you want to do this" without at least trying to understand the problem. Escpecially when it comes to then need for partial mocking there are really a lot of use cases that I could imagine where it would be useful. That's why the guys from Mockito provided that functionality. This feature should of course not be overused. But when we talk about test case setups that otherwise could not be established in a very complicated way, spying should be used.
// Setup
var myArray = [["John", 23], ["cat", 2]];
// Only change code below this line
var removedFromMyArray;
removedFromMyArray = myArray.pop()
Check out Join (SQL) on Wikipedia
left / right (outer) join - Given two tables returns all rows that exist in either the left or right table of your join, plus the rows from the other side will be returned when the join clause is a match or null will be returned for those columns
Full Outer - Given two tables returns all rows, and will return nulls when either the left or right column is not there
Cross Joins - Cartesian join and can be dangerous if not used carefully
if you need a lighter solution i recommend mysql-shell, install using the command below.
brew cask install mysql-shell
To start after installation type mysqlsh.
The solution suggested
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" >
<remove name="UrlRoutingModule"/>
</modules>
</system.webServer>
works, but can degrade performance and can even cause errors, because now all registered HTTP modules run on every request, not just managed requests (e.g. .aspx). This means modules will run on every .jpg .gif .css .html .pdf etc.
A more sensible solution is to include this in your web.config:
<system.webServer>
<modules>
<remove name="UrlRoutingModule-4.0" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
</modules>
</system.webServer>

Playing an audio file ensures full background Javascript performance for the time being
For me, it was the simplest and least intrusive solution - apart from playing a faint / almost-empty sound, there are no other potential side effects
You can find the details here: https://stackoverflow.com/a/51191818/914546
(From other answers, I see that some people use different properties of the Audio tag, I do wonder whether it's possible to use the Audio tag for full performance, without actually playing something)
Here are three statements for three different dates in the form with three type=date fields.
$inv_date
is the current date:

$inv_date_from = date("Y") . "-" . date("m") . "-" . "01";
$inv_date_to
is the last day of the month:
$inv_date_to = date("Y-m-t", strtotime(date("Y-m-t")));
I hope this helps :)
My issue was calling my program with the same name as one of its cocoapods. It caused a conflict. Solution: Create a program different name.
If you hit = and expect to see line numbers, but only see byte counts, then line numbers are turned off. Hit -n to turn them on, and make sure $LESS
doesn't include 'n'.
Turning off line numbers by default (for example, setting LESS=n
) speeds up searches in very large files. It is handy if you frequently search through big files, but don't usually care which line you're on.
I typically run with LESS=RSXin
(escape codes enabled, long lines chopped, don't clear the screen on exit, ignore case on all lower case searches, and no line number counting by default) and only use -n or -S from inside less
as needed.
I have joined the answer from Lucas and "ASP.NET MVC Helpers, Merging two object htmlAttributes together" and plus controllerName to following code:

<ctype.h>
includes a range of functions for determining if a char
represents a letter or a number, such as isalpha
, isdigit
and isalnum
.
The reason why int a = (int)theChar
won't do what you want is because a
will simply hold the integer value that represents a specific character. For example the ASCII number for '9'
is 57, and for 'a'
it's 97.
Also for ASCII:
if (theChar >= '0' && theChar <= '9')
if (theChar >= 'A' && theChar <= 'Z' || theChar >= 'a' && theChar <= 'z')
Take a look at an ASCII table to see for yourself.
Another base solution
group_sorted <- group[order(group$Subject, -group$pt),]
group_sorted[!duplicated(group_sorted$Subject),]
# Subject pt Event
# 1 5 2
# 2 17 2
# 3 5 2
Order the data frame by pt
(descending) and then remove rows duplicated in Subject
Matching any text but those matching a pattern is usually achieved with splitting the string with the regex pattern.
Examples:
Regex.Split(text, @"red|green|blue")
or, to get rid of empty values, Regex.Split(text, @"red|green|blue").Where(x => !string.IsNullOrEmpty(x))
(see demo)Regex.Split(text, "red|green|blue")
or, to remove empty items, Regex.Split(text, "red|green|blue").Where(Function(s) Not String.IsNullOrWhitespace(s))
(see demo, or this demo where LINQ is supported)text.split(/red|green|blue/)
(no need to use g
modifier here!) (to get rid of empty values, use text.split(/red|green|blue/).filter(Boolean)
), see demotext.split("red|green|blue")
, or - to keep all trailing empty items - use text.split("red|green|blue", -1)
, or to remove all empty items use more code to remove them (see demo)text.split(/red|green|blue/)
, to get all trailing items use text.split(/red|green|blue/, -1)
and to remove all empty items use text.split(/red|green|blue/).findAll {it != ""})
(see demo)text.split(Regex("red|green|blue"))
or, to remove blank items, use text.split(Regex("red|green|blue")).filter{ !it.isBlank() }
, see demotext.split("red|green|blue")
, or to keep all trailing empty items, use text.split("red|green|blue", -1)
and to remove all empty items, use text.split("red|green|blue").filter(_.nonEmpty)
(see demo)text.split(/red|green|blue/)
, to get rid of empty values use .split(/red|green|blue/).reject(&:empty?)
(and to get both leading and trailing empty items, use -1
as the second argument, .split(/red|green|blue/, -1)
) (see demo)my @result1 = split /red|green|blue/, $text;
, or with all trailing empty items, my @result2 = split /red|green|blue/, $text, -1;
, or without any empty items, my @result3 = grep { /\S/ } split /red|green|blue/, $text;
(see demo)preg_split('~red|green|blue~', $text)
or preg_split('~red|green|blue~', $text, -1, PREG_SPLIT_NO_EMPTY)
to output no empty items (see demo)re.split(r'red|green|blue', text)
or, to remove empty items, list(filter(None, re.split(r'red|green|blue', text)))
(see demo)regexp.MustCompile("red|green|blue").Split(text, -1)
, and if you need to remove empty items, use this code. See Go demo.NOTE: If you patterns contain capturing groups, regex split functions/methods may behave differently, also depending on additional options. Please refer to the appropriate split method documentation then.
Most options are alredy mentioned. To print template context, I've created a simple library for that. See https://github.com/edoburu/django-debugtools
You can use it to print template context without any {% load %}
construct:
{% print var %} prints variable
{% print %} prints all
It uses a customized pprint format to display the variables in a <pre>
tag.
netstat -ano|find ":port_no"
will give you the list.
a: Displays all connections and listening ports.
n: Displays addresses and port numbers in numerical form.
o: Displays the owning process ID associated with each connection .
example : netstat -ano | find ":1900"
This gives you the result like this.
UDP 107.109.121.196:1900 *:* 1324
UDP 127.0.0.1:1900 *:* 1324
UDP [::1]:1900 *:* 1324
UDP [fe80::8db8:d9cc:12a8:2262%13]:1900 *:* 1324
According to Fixture finalization / executing teardown code, the current best practice for setup and teardown is to use yield
instead of return
:
import pytest
@pytest.fixture()
def resource():
print("setup")
yield "resource"
print("teardown")
class TestResource:
def test_that_depends_on_resource(self, resource):
print("testing {}".format(resource))
Running it results in
$ py.test --capture=no pytest_yield.py
=== test session starts ===
platform darwin -- Python 2.7.10, pytest-3.0.2, py-1.4.31, pluggy-0.3.1
collected 1 items
pytest_yield.py setup
testing resource
.teardown
=== 1 passed in 0.01 seconds ===
Another way to write teardown code is by accepting a request
-context object into your fixture function and calling its request.addfinalizer
method with a function that performs the teardown one or multiple times:
import pytest
@pytest.fixture()
def resource(request):
print("setup")
def teardown():
print("teardown")
request.addfinalizer(teardown)
return "resource"
class TestResource:
def test_that_depends_on_resource(self, resource):
print("testing {}".format(resource))
The below code worked fine:
Run Keyword if '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2' LOG HELLO
The -jar option is mutually exclusive of -classpath. See an old description here
-jar
Execute a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. In order for this option to work, the manifest of the JAR file must contain a line of the form Main-Class: classname. Here, classname identifies the class having the public static void main(String[] args) method that serves as your application's starting point.
See the Jar tool reference page and the Jar trail of the Java Tutorial for information about working with Jar files and Jar-file manifests.
When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored.
A quick and dirty hack is to append your classpath to the bootstrap classpath:
-Xbootclasspath/a:path
Specify a colon-separated path of directires, JAR archives, and ZIP archives to append to the default bootstrap class path.
However, as @Dan rightly says, the correct solution is to ensure your JARs Manifest contains the classpath for all JARs it will need.
function in_array(needle, haystack){
return haystack.indexOf(needle) !== -1;
}
From Python 3.7, there is a new math.remainder()
function:
from math import remainder
print(remainder(26,7))
Output:
-2.0 # not 5
Note, as above, it's not the same as %
.
Quoting the documentation:
math.remainder(x, y)
Return the IEEE 754-style remainder of x with respect to y. For finite x and finite nonzero y, this is the difference x - n*y, where n is the closest integer to the exact value of the quotient x / y. If x / y is exactly halfway between two consecutive integers, the nearest even integer is used for n. The remainder r = remainder(x, y) thus always satisfies abs(r) <= 0.5 * abs(y).
Special cases follow IEEE 754: in particular, remainder(x, math.inf) is x for any finite x, and remainder(x, 0) and remainder(math.inf, x) raise ValueError for any non-NaN x. If the result of the remainder operation is zero, that zero will have the same sign as x.
On platforms using IEEE 754 binary floating-point, the result of this operation is always exactly representable: no rounding error is introduced.
Issue29962 describes the rationale for creating the new function.
Try closing and reopening the file, then press Ctrl+F11
.
Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.
Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.
Yes, the browser caches images for you, automatically.
You can, however, set an image cache to expire. Check out this Stack Overflow questions and answer:
I think one should use singleton pattern to avoid having to create instances of the HttpClient and closing it all the time. If you are using .Net 4.0 you could use a sample code as below. for more information on singleton pattern check here.
class HttpClientSingletonWrapper : HttpClient
{
private static readonly Lazy<HttpClientSingletonWrapper> Lazy= new Lazy<HttpClientSingletonWrapper>(()=>new HttpClientSingletonWrapper());
public static HttpClientSingletonWrapper Instance {get { return Lazy.Value; }}
private HttpClientSingletonWrapper()
{
}
}
Use the code as below.
var client = HttpClientSingletonWrapper.Instance;
If you just want to do a literal replace in java, use Pattern.quote(string)
to escape any string to a literal.
myString.replaceAll(Pattern.quote(matchingStr), replacementStr)
You can be used this step is very useful:
for i in `ls -l folder1 | grep -v total | awk '{print $ ( ? )}'`
do
cd folder1
cp $i folder2/$i.`date +%m%d%Y`
done
If you dataframe is df
you can simply use:
import matplotlib.pyplot as plt
import seaborn as sns
plt.figure(figsize=(15, 10))
sns.heatmap(df.corr(), annot=True)
If you don't handle exception, before terminating the program, JVM executes finally block. It will not executed only if normal execution of program will fail mean's termination of program due to these following reasons..
By causing a fatal error that causes the process to abort.
Termination of program due to memory corrupt.
By calling System.exit()
If program goes into infinity loop.
I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.
Check this answer for C++11. Basically, if you pass an lvalue the rvalue reference
From this article:
void f1(String s) {
vector<String> v;
v.push_back(std::move(s));
}
void f2(const String &s) {
vector<String> v;
v.push_back(s);
}
"For lvalue argument, ‘f1’ has one extra copy to pass the argument because it is by-value, while ‘f2’ has one extra copy to call push_back. So no difference; for rvalue argument, the compiler has to create a temporary ‘String(L“”)’ and pass the temporary to ‘f1’ or ‘f2’ anyway. Because ‘f2’ can take advantage of move ctor when the argument is a temporary (which is an rvalue), the costs to pass the argument are the same now for ‘f1’ and ‘f2’."
Continuing: " This means in C++11 we can get better performance by using pass-by-value approach when:
"
OTOH, for C++98 it is best to pass by reference - less data gets copied around. Passing const or non const depend of whether you need to change the argument or not.
Even later to the party.
function zfill(num, len) {
return(0 > num ? "-" : "") + (Math.pow(10, len) <= Math.abs(num) ? "0" + Math.abs(num) : Math.pow(10, len) + Math.abs(num)).toString().substr(1)
}
This handles negatives and situations where the number is longer than the field width. And floating-point.
Follow these steps then you can create custom styles for your file upload form:
1.) This is the simple HTML form(please read the HTML comments I have written here bellow)
<form action="#type your action here" method="POST" enctype="multipart/form-data">
<div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" onclick="getFile()">Click to upload!</div>
<!-- this is your file input tag, so i hide it!-->
<div style='height: 0px;width: 0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<input type="submit" value='submit' >
</form>
2.) Then use this simple script to pass the click event to file input tag.
function getFile(){
document.getElementById("upfile").click();
}
Now you can use any type of a styling without worrying how to change default styles. I know this very well, because I have been trying to change the default styles for month and a half. believe me it's very hard because different browsers have different upload input tag. So use this one to build your custom file upload forms.Here is the full AUTOMATED UPLOAD code.
<html>
<style>
#yourBtn{
position: relative;
top: 150px;
font-family: calibri;
width: 150px;
padding: 10px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border: 1px dashed #BBB;
text-align: center;
background-color: #DDD;
cursor:pointer;
}
</style>
<script type="text/javascript">
function getFile(){
document.getElementById("upfile").click();
}
function sub(obj){
var file = obj.value;
var fileName = file.split("\\");
document.getElementById("yourBtn").innerHTML = fileName[fileName.length-1];
document.myForm.submit();
event.preventDefault();
}
</script>
<body>
<center>
<form action="#type your action here" method="POST" enctype="multipart/form-data" name="myForm">
<div id="yourBtn" onclick="getFile()">click to upload a file</div>
<!-- this is your file input tag, so i hide it!-->
<!-- i used the onchange event to fire the form submission-->
<div style='height: 0px; width: 0px;overflow:hidden;'><input id="upfile" type="file" value="upload" onchange="sub(this)"/></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<!-- <input type="submit" value='submit' > -->
</form>
</center>
</body>
</html>
This worked for me.

Register keyword tells compiler to store the particular variable in CPU registers so that it could be accessible fast. From a programmer's point of view register keyword is used for the variables which are heavily used in a program, so that compiler can speedup the code. Although it depends on the compiler whether to keep the variable in CPU registers or main memory.
we can create nested cte.please see the below cte in example

}
}
usage:
let myView = NSView(frame: NSRect(x: 0, y: 0, width: 100, height: 100))
print(myView.backgroundColor ?? "none") // NSView's background hasn't been set yet = nil
myView.backgroundColor = .red // set NSView's background color to red color
print(myView.backgroundColor ?? "none")
view.addSubview(myView)
For your first question, find the position of some value in a list x using index(), like so:
x.index(value)
For your second question, to check for multiple same values you should split your list into chunks and use the same logic from above. They say divide and conquer. It works. Try this:
value = 1
x = [1,2,3,4,5,6,2,1,4,5,6]
chunk_a = x[:int(len(x)/2)] # get the first half of x
chunk_b = x[int(len(x)/2):] # get the rest half of x
print(chunk_a.index(value))
print(chunk_b.index(value))
Hope that helps!
I think you are a bit confused on the purpose of custom data attributes. From the w3 spec
Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements.
By itself an attribute of data-toggle=value
is basically a key-value pair, in which the key is "data-toggle" and the value is "value".
In the context of Bootstrap, the custom data in the attribute is almost useless without the context that their JavaScript library includes for the data. If you look at the non-minified version of bootstrap.js then you can do a search for "data-toggle" and find how it is being used.
Here is an example of Bootstrap JavaScript code that I copied straight from the file regarding the use of "data-toggle".
Button Toggle
Button.prototype.toggle = function () {
var changed = true
var $parent = this.$element.closest('[data-toggle="buttons"]')
if ($parent.length) {
var $input = this.$element.find('input')
if ($input.prop('type') == 'radio') {
if ($input.prop('checked') && this.$element.hasClass('active')) changed = false
else $parent.find('.active').removeClass('active')
}
if (changed) $input.prop('checked', !this.$element.hasClass('active')).trigger('change')
} else {
this.$element.attr('aria-pressed', !this.$element.hasClass('active'))
}
if (changed) this.$element.toggleClass('active')
}
The context that the code provides shows that Bootstrap is using the data-toggle
attribute as a custom query selector to process the particular element.
From what I see these are the data-toggle options:
You may want to look at the Bootstrap JavaScript documentation to get more specifics of what each do, but basically the data-toggle
attribute toggles the element to active or not.
Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.
Short answer to your question: Yes there are other stuff included than whats in the list.
What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.
From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.
Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.
Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.
Use regular expression is best way to doing this as already mentioned by ashish sahu
public int getInt(String s){
return Integer.parseInt(s.replaceAll("[\\D]", ""));
}
You can also use np.size(a,1), 1 here is the axis and this will give you the number of columns
Why don't you simply use set_index
method?
In : col = ['a','b','c']
In : data = DataFrame([[1,2,3],[10,11,12],[20,21,22]],columns=col)
In : data
Out:
a b c
0 1 2 3
1 10 11 12
2 20 21 22
In : data2 = data.set_index('a')
In : data2
Out:
b c
a
1 2 3
10 11 12
20 21 22
If you execute your Spring Boot application as a linux service (e.g. init.d script or similar), then you have the following option as well: Create a file called yourApplication.conf and put it next to your executable war/jar file. It's content should be something similar:
JAVA_OPTS="
-Djavax.net.ssl.trustStore=path-to-your-trustStore-file
-Djavax.net.ssl.trustStorePassword=yourCrazyPassword
"
Java Usage example: myMenuItem.setIcon(android.R.drawable.ic_menu_save);
Resource Usage example: android:icon="@android:drawable/ic_menu_save"
To add to Jefromi's answer, if you don't want to place a meaningless merge in the history of the source
branch, you can create a temporary branch for the ours
merge, then throw it away:
git checkout <source>
git checkout -b temp # temporary branch for merge
git merge -s ours <target> # create merge commit with contents of <source>
git checkout <target> # fast forward <target> to merge commit
git merge temp # ...
git branch -d temp # throw temporary branch away
That way the merge commit will only exist in the history of the target
branch.
Alternatively, if you don't want to create a merge at all, you can simply grab the contents of source
and use them for a new commit on target
:
git checkout <source> # fill index with contents of <source>
git symbolic-ref HEAD <target> # tell git we're committing on <target>
git commit -m "Setting contents to <source>" # make an ordinary commit with the contents of <source>
The Date
documentation states that :
The JavaScript date is based on a time value that is milliseconds since midnight January 1, 1970, UTC
Click on start button then on end button. It will show you the number of seconds between the 2 clicks.
The milliseconds diff is in variable timeDiff
. Play with it to find seconds/minutes/hours/ or what you need
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = new Date();_x000D_
};_x000D_
_x000D_
function end() {_x000D_
endTime = new Date();_x000D_
var timeDiff = endTime - startTime; //in ms_x000D_
// strip the ms_x000D_
timeDiff /= 1000;_x000D_
_x000D_
// get seconds _x000D_
var seconds = Math.round(timeDiff);_x000D_
console.log(seconds + " seconds");_x000D_
}
_x000D_
<button onclick="start()">Start</button>_x000D_
_x000D_
<button onclick="end()">End</button>
_x000D_
OR another way of doing it for modern browser
Using performance.now()
which returns a value representing the time elapsed since the time origin. This value is a double with microseconds in the fractional.
The time origin is a standard time which is considered to be the beginning of the current document's lifetime.
var startTime, endTime;_x000D_

Normally, mutt sets the From:
header based on the from
configuration variable you set in ~/.muttrc
:
set from="Fubar <foo@bar>"
If this is not set, mutt
uses the EMAIL
environment variable by default. In which case, you can get away with calling mutt like this on the command line (as opposed to how you showed it in your comment):
EMAIL="foo@bar" mutt -s '$MailSubject' -c "abc@def"
However, if you want to be able to edit the From:
header while composing, you need to configure mutt
to allow you to edit headers first. This involves adding the following line in your ~/.muttrc
:
set edit_headers=yes
After that, next time you open up mutt and are composing an E-mail, your chosen text editor will pop up containing the headers as well, so you can edit them. This includes the From:
header.
This answer is all about authorization and it is a complement of my previous answer about authentication
Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.
@Secured
annotationBesides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.
Create an enumeration and define the roles according to your needs:
public enum Role {
ROLE_1,
ROLE_2,
ROLE_3
}
Change the @Secured
name binding annotation created before to support roles:
@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
Role[] value() default {};
}
And then annotate the resource classes and methods with @Secured
to perform the authorization. The method annotations will override the class annotations:
@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {
@GET
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response myMethod(@PathParam("id") Long id) {
// This method is not annotated with @Secured
// But it's declared within a class annotated with @Secured({Role.ROLE_1})
// So it only can be executed by the users who have the ROLE_1 role
...
}
@DELETE
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
@Secured({Role.ROLE_1, Role.ROLE_2})
public Response myOtherMethod(@PathParam("id") Long id) {
// This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
// The method annotation overrides the class annotation
// So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
...
}
}
Create a filter with the AUTHORIZATION
priority, which is executed after the AUTHENTICATION
priority filter defined previously.
The ResourceInfo
can be used to get the resource Method
and resource Class
that will handle the request and then extract the @Secured
annotations from them:
@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
// Get the resource class which matches with the requested URL
// Extract the roles declared by it
Class<?> resourceClass = resourceInfo.getResourceClass();
List<Role> classRoles = extractRoles(resourceClass);
// Get the resource method which matches with the requested URL
// Extract the roles declared by it
Method resourceMethod = resourceInfo.getResourceMethod();
List<Role> methodRoles = extractRoles(resourceMethod);
try {
// Check if the user is allowed to execute the method
// The method annotations override the class annotations
if (methodRoles.isEmpty()) {
checkPermissions(classRoles);
} else {
checkPermissions(methodRoles);
}
} catch (Exception e) {
requestContext.abortWith(
Response.status(Response.Status.FORBIDDEN).build());
}
}
// Extract the roles from the annotated element
private List<Role> extractRoles(AnnotatedElement annotatedElement) {
if (annotatedElement == null) {
return new ArrayList<Role>();
} else {
Secured secured = annotatedElement.getAnnotation(Secured.class);
if (secured == null) {
return new ArrayList<Role>();
} else {
Role[] allowedRoles = secured.value();
return Arrays.asList(allowedRoles);
}
}
}
private void checkPermissions(List<Role> allowedRoles) throws Exception {
// Check if the user contains one of the allowed roles
// Throw an Exception if the user has not permission to execute the method
}
}
If the user has no permission to execute the operation, the request is aborted with a 403
(Forbidden).
To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext
(which should be already set in the ContainerRequestContext
) or inject it using CDI, depending on the approach you go for.
If a @Secured
annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.
Alternatively to defining the roles in the @Secured
annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed
, @PermitAll
and @DenyAll
.
JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:
@DenyAll
on the method takes precedence over @RolesAllowed
and @PermitAll
on the class.@RolesAllowed
on the method takes precedence over @PermitAll
on the class.@PermitAll
on the method takes precedence over @RolesAllowed
on the class.@DenyAll
can't be attached to classes.@RolesAllowed
on the class takes precedence over @PermitAll
on the class.So an authorization filter that checks JSR-250 annotations could be like:
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
Method method = resourceInfo.getResourceMethod();
// @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
if (method.isAnnotationPresent(DenyAll.class)) {
refuseRequest();
}
// @RolesAllowed on the method takes precedence over @PermitAll
RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
return;
}
// @PermitAll on the method takes precedence over @RolesAllowed on the class
if (method.isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}

If one is used to work with DLL in Windows and would like to skip .so version numbers in linux/QT, adding CONFIG += plugin
will take version numbers out. To use absolute path to .so, giving it to linker works fine, as Mr. Klatchko mentioned.
Instead of wading through the description of all the options, you can jump to 3.4.3 Short Options Cross Reference
under the info tar
command.
x
means --extract
. v
means --verbose
. f
means --file
. z
means --gzip
. You can combine one-letter arguments together, and f
takes an argument, the filename. There is something you have to watch out for:
Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below). When short options are clumped as a set, use one (single) dash for them all, e.g., ''tar' -cvf'. Only the last option in such a set is allowed to have an argument(1).
This old way of writing 'tar' options can surprise even experienced users. For example, the two commands:tar cfz archive.tar.gz file tar -cfz archive.tar.gz file
are quite different. The first example uses 'archive.tar.gz' as the value for option 'f' and recognizes the option 'z'. The second example, however, uses 'z' as the value for option 'f' -- probably not what was intended.

The feedback you get on the interactive interpreter uses repr
too. When you type in an expression (let it be expr
), the interpreter basically does result = expr; if result is not None: print repr(result)
. So the second line in your example is formatting the string foo
into the representation you want ('foo'
). And then the interpreter creates the repr
esentation of that, leaving you with double quotes.
Why when I combine %r with double-quote and single quote escapes and print them out, it prints it the way I'd write it in my .py file but not the way I'd like to see it?
I'm not sure what you're asking here. The text single ' and double " quotes
, when run through repr
, includes escapes for one kind of quote. Of course it does, otherwise it wouldn't be a valid string literal by Python rules. That's precisely what you asked for by calling repr
.
Also note that the eval(repr(x)) == x
analogy isn't meant literal. It's an approximation and holds true for most (all?) built-in types, but the main thing is that you get a fairly good idea of the type and logical "value" from looking the the repr
output.
The previous answers have lost the first frame. And it will be nice to store the images in a folder.
# create a folder to store extracted images
import os
folder = 'test'
os.mkdir(folder)
# use opencv to do the job
import cv2
print(cv2.__version__) # my version is 3.1.0
vidcap = cv2.VideoCapture('test_video.mp4')
count = 0
while True:
success,image = vidcap.read()
if not success:
break
cv2.imwrite(os.path.join(folder,"frame{:d}.jpg".format(count)), image) # save frame as JPEG file
count += 1
print("{} images are extacted in {}.".format(count,folder))
By the way, you can check the frame rate by VLC. Go to windows -> media information -> codec details
Two more ways to do it (see my comment on the previous answer by @Tomasz Nurkiewicz):
The first relies on the fact that the compiler simply won't let you pass in something of the wrong type:
when(a.method(any(Class.class))).thenReturn(b);
You lose the exact typing (the Class<? extends A>
) but it probably works as you need it to.
The second is a lot more involved but is arguably a better solution if you really want to be sure that the argument to method()
is an A
or a subclass of A
:
when(a.method(Matchers.argThat(new ClassOrSubclassMatcher<A>(A.class)))).thenReturn(b);
Where ClassOrSubclassMatcher
is an org.hamcrest.BaseMatcher
defined as:
public class ClassOrSubclassMatcher<T> extends BaseMatcher<Class<T>> {
private final Class<T> targetClass;
public ClassOrSubclassMatcher(Class<T> targetClass) {
this.targetClass = targetClass;
}
@SuppressWarnings("unchecked")
public boolean matches(Object obj) {
if (obj != null) {
if (obj instanceof Class) {
return targetClass.isAssignableFrom((Class<T>) obj);
}
}
return false;
}
public void describeTo(Description desc) {
desc.appendText("Matches a class or subclass");
}
}
Phew! I'd go with the first option until you really need to get finer control over what method()
actually returns :-)
You normally forward the request to a JSP for display. JSP is a view technology which provides a template to write plain vanilla HTML/CSS/JS in and provides ability to interact with backend Java code/variables with help of taglibs and EL. You can control the page flow with taglibs like JSTL. You can set any backend data as an attribute in any of the request, session or application scope and use EL (the ${}
things) in JSP to access/display them. You can put JSP files in /WEB-INF
folder to prevent users from directly accessing them without invoking the preprocessing servlet.
Kickoff example:
@WebServlet("/hello")
public class HelloWorldServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String message = "Hello World";
request.setAttribute("message", message); // This will be available as ${message}
request.getRequestDispatcher("/WEB-INF/hello.jsp").forward(request, response);
}
}
And /WEB-INF/hello.jsp
look like:
<!DOCTYPE html>
<html lang="en">
<head>
<title>SO question 2370960</title>
</head>
<body>
<p>Message: ${message}</p>
</body>
</html>
When opening http://localhost:8080/contextpath/hello this will show
Message: Hello World
in the browser.

Get data from the URL and then call json.loads
e.g.
Python3 example:
import urllib.request, json
with urllib.request.urlopen("http://maps.googleapis.com/maps/api/geocode/json?address=google") as url:
data = json.loads(url.read().decode())
print(data)
Python2 example:
import urllib, json
url = "http://maps.googleapis.com/maps/api/geocode/json?address=google"
response = urllib.urlopen(url)
data = json.loads(response.read())
print data
The output would result in something like this:
{
"results" : [
{
"address_components" : [
{
"long_name" : "Charleston and Huff",
"short_name" : "Charleston and Huff",
"types" : [ "establishment", "point_of_interest" ]
},
{
"long_name" : "Mountain View",
"short_name" : "Mountain View",
"types" : [ "locality", "political" ]
},
{
...
And for what it's worth, on Chrome 26.0.1410.65, Firefox 19.0.2, and Safari 6.0.3 at least, if you have multiple elements with the same ID, jquery selectors (at least) will return the first element with that ID.
e.g.
<div id="one">first text for one</div>
<div id="one">second text for one</div>
and
alert($('#one').size());
See http://jsfiddle.net/RuysX/ for a test.
$.ajax({
url: "target.php",
type: "post",
data: "fname="+fname+"&lname="+lname,
}).done(function(data) {
alert(data);
});

As others have already said, parameters passed through the command line can be accessed in batch files with the notation %1
to %9
. There are also two other tokens that you can use:
%0
is the executable (batch file) name as specified in the command line.%*
is all parameters specified in the command line -- this is very useful if you want to forward the parameters to another program.There are also lots of important techniques to be aware of in addition to simply how to access the parameters.
This is done with constructs like IF "%~1"==""
, which is true if and only if no arguments were passed at all. Note the tilde character which causes any surrounding quotes to be removed from the value of %1
; without a tilde you will get unexpected results if that value includes double quotes, including the possibility of syntax errors.
If you need to access more than 9 arguments you have to use the command SHIFT
. This command shifts the values of all arguments one place, so that %0
takes the value of %1
, %1
takes the value of %2
, etc. %9
takes the value of the tenth argument (if one is present), which was not available through any variable before calling SHIFT
(enter command SHIFT /?
for more options).
SHIFT
is also useful when you want to easily process parameters without requiring that they are presented in a specific order. For example, a script may recognize the flags -a
and -b
in any order. A good way to parse the command line in such cases is
:parse
IF "%~1"=="" GOTO endparse
IF "%~1"=="-a" REM do something
IF "%~1"=="-b" REM do something else
SHIFT
GOTO parse
:endparse
REM ready for action!
This scheme allows you to parse pretty complex command lines without going insane.
For parameters that represent file names the shell provides lots of functionality related to working with files that is not accessible in any other way. This functionality is accessed with constructs that begin with %~
.
For example, to get the size of the file passed in as an argument use
ECHO %~z1
To get the path of the directory where the batch file was launched from (very useful!) you can use
ECHO %~dp0
You can view the full range of these capabilities by typing CALL /?
in the command prompt.

For a 64-bit JVM running in a 64-bit OS on a 64-bit machine, is there any limit besides the theoretical limit of 2^64 bytes or 16 exabytes?
You also have to take hardware limits into account. While pointers may be 64bit current CPUs can only address a less than 2^64 bytes worth of virtual memory.
With uncompressed pointers the hotspot JVM needs a continuous chunk of virtual address space for its heap. So the second hurdle after hardware is the operating system providing such a large chunk, not all OSes support this.
And the third one is practicality. Even if you can have that much virtual memory it does not mean the CPUs support that much physical memory, and without physical memory you will end up swapping, which will adversely affect the performance of the JVM because the GCs generally have to touch a large fraction of the heap.
As other answers mention compressed oops: By bumping the object alignment higher than 8 bytes the limits with compressed oops can be increased beyond 32GB
Sometimes the command
adb -s emulator-5554 emu kill

This issue can occur if the Azure Active Directory Module for Windows PowerShell isn't loaded correctly.
To resolve this issue, follow these steps.
1.Install the Azure Active Directory Module for Windows PowerShell on the computer (if it isn't already installed). To install the Azure Active Directory Module for Windows PowerShell, go to the following Microsoft website:
Manage Azure AD using Windows PowerShell
2.If the MSOnline module isn't present, use Windows PowerShell to import the MSOnline module.
Import-Module MSOnline
After it complete, we can use this command to check it.
PS C:\Users> Get-Module -ListAvailable -Name MSOnline*
Directory: C:\windows\system32\WindowsPowerShell\v1.0\Modules
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Manifest 1.1.166.0 MSOnline {Get-MsolDevice, Remove-MsolDevice, Enable-MsolDevice, Disable-MsolDevice...}
Manifest 1.1.166.0 MSOnlineExtended {Get-MsolDevice, Remove-MsolDevice, Enable-MsolDevice, Disable-MsolDevice...}
More information about this issue, please refer to it.
Update:
We should import azure AD powershell to VS 2015, we can add tool and select Azure AD powershell.
There are 2 annotations in Spring: @RequestBody and @ResponseBody. These annotations consumes, respectively produces JSONs. Some more info here.
2012 This is a better solution for this scenario (tested With Visual Studio 2008):
Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
config.AppSettings.Settings.Remove("MyVariable");
config.AppSettings.Settings.Add("MyVariable", "MyValue");
config.Save();
Update 2018 =>
Tested in vs 2015 - Asp.net MVC5
var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
config.Save();
if u need to checking element exist, use this code:
var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
if (config.AppSettings.Settings["MyVariable"] != null)
{
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
}
else { config.AppSettings.Settings.Add("MyVariable", "MyValue"); }
config.Save();
You can reload using /etc/init.d/nginx reload
and sudo service nginx reload
If nginx -t
throws some error then it won't reload
so use && to run both at a same time
like
nginx -t && /etc/init.d/nginx reload
You need to escape <
and &
. Escaping >
too doesn't hurt:
function magic(input) {
input = input.replace(/&/g, '&');
input = input.replace(/</g, '<');
input = input.replace(/>/g, '>');
return input;
}
Or you let the DOM engine do the dirty work for you (using jQuery because I'm lazy):
function magic(input) {
return $('<span>').text(input).html();
}
What this does is creating a dummy element, assigning your string as its textContent (i.e. no HTML-specific characters have side effects since it's just text) and then you retrieve the HTML content of that element - which is the text but with special characters converted to HTML entities in cases where it's necessary.
if you know the index of the item of default value,just
lstDepartment.SelectedIndex = 1;//the second item
or if you know the value you want to set, just
lstDepartment.SelectedValue = "the value you want to set";
In my case, I had to execute a process if one of these conditions were true: if a previous process was completed or if 5 seconds had already passed. So, I did the following and worked pretty well:
private Runnable mStatusChecker;
private Handler mHandler;
class {
method() {
mStatusChecker = new Runnable() {
int times = 0;
@Override
public void run() {
if (times < 5) {
if (process1.isRead()) {
executeProcess2();
} else {
times++;
mHandler.postDelayed(mStatusChecker, 1000);
}
} else {
executeProcess2();
}
}
};
mHandler = new Handler();
startRepeatingTask();
}
void startRepeatingTask() {
mStatusChecker.run();
}
void stopRepeatingTask() {
mHandler.removeCallbacks(mStatusChecker);
}
}
If process1 is read, it executes process2. If not, it increments the variable times, and make the Handler be executed after one second. It maintains a loop until process1 is read or times is 5. When times is 5, it means that 5 seconds passed and in each second, the if clause of process1.isRead() is executed.
That's because you created a Web Site instead of a Web Application. The cs/vb
files can only be seen in a Web Application, but in a website you can't have a separate cs/vb
file.
Edit: In the website you can add a cs file behavior like..
<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>
~/Global.asax.cs:
namespace ApplicationName
{
public partial class MyApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
}
}
}
My solution was extremely close to Joel's (Not Etherton, just plain Joel):
public partial class WaitingDialog : Form
{
public WaitingDialog()
{
InitializeComponent();
SetStyle(ControlStyles.SupportsTransparentBackColor, true);
this.BackColor = Color.Transparent;
this.TransparencyKey = Color.Transparent; // I had to add this to get it to work.
// Other stuff
}
protected override void OnPaintBackground(PaintEventArgs e) { /* Ignore */ }
}
Well I'm sure that this is the simplest way to populate JTable from ResultSet, without any external library. I have included comments in this method.
public void resultSetToTableModel(ResultSet rs, JTable table) throws SQLException{
//Create new table model
DefaultTableModel tableModel = new DefaultTableModel();
//Retrieve meta data from ResultSet
ResultSetMetaData metaData = rs.getMetaData();
//Get number of columns from meta data
int columnCount = metaData.getColumnCount();
//Get all column names from meta data and add columns to table model
for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++){
tableModel.addColumn(metaData.getColumnLabel(columnIndex));
}
//Create array of Objects with size of column count from meta data
Object[] row = new Object[columnCount];
//Scroll through result set
while (rs.next()){
//Get object from column with specific index of result set to array of objects
for (int i = 0; i < columnCount; i++){
row[i] = rs.getObject(i+1);
}
//Now add row to table model with that array of objects as an argument
tableModel.addRow(row);
}
//Now add that table model to your table and you are done :D
table.setModel(tableModel);
}
Please find below the code that generates automatically the content of the txt local file and display it html. Good luck!

All of the answers above are very good but I cleaned it up a little bit.
This solution automatically puts the name of the submit button pressed into the action hidden field. Both the javascript on the page and the server code can check the action hidden field value as needed.
The solution uses jquery to automatically apply to all submit buttons.
<input type="hidden" name="action" id="action" />
<script language="javascript" type="text/javascript">
$(document).ready(function () {
//when a submit button is clicked, put its name into the action hidden field
$(":submit").click(function () { $("#action").val(this.name); });
});
</script>
<input type="submit" class="bttn" value="<< Back" name="back" />
<input type="submit" class="bttn" value="Finish" name="finish" />
<input type="submit" class="bttn" value="Save" name="save" />
<input type="submit" class="bttn" value="Next >>" name="next" />
<input type="submit" class="bttn" value="Delete" name="delete" />
<input type="button" class="bttn" name="cancel" value="Cancel" onclick="window.close();" />
Then write code like this into your form submit handler.
if ($("#action").val() == "delete") {
return confirm("Are you sure you want to delete the selected item?");
}
Try this and then tell me the results:
UPDATE File1 AS B
SET b.campo1 = (SELECT DISTINCT A.campo1
FROM File2 A
INNER JOIN File1
ON A.campo2 = File1.campo2
AND A.campo2 = B.campo2)
I have a field named IsActive in table rows that's True when an item has been deleted. This code applies a CSS class named strikethrough only to deleted items. You can see how it uses the C# Ternary Operator:
<tr class="@(@businesstypes.IsActive ? "" : "strikethrough")">
Just add these lines
override fun onBackPressed() {
if(navController.popBackStack().not()) {
//Last fragment: Do your operation here
finish()
}
navController.popBackStack() will just pop your fragment if this is not your last fragment
The @supports rule (92% browser support July 2017) rule can be used for conditional logic on css properties:
@supports (display: -webkit-box) {
.for_older_webkit_browser { display: -webkit-box }
}
@supports not (display: -webkit-box) {
.newer_browsers { display: flex }
}
In a nutshell it means.. You are trying to access an object without instantiating it.. You might need to use the "new" keyword to instantiate it first i.e create an instance of it.
For eg:
public class MyClass
{
public int Id {get; set;}
}
MyClass myClass;
myClass.Id = 0; <----------- An error will be thrown here.. because myClass is null here...
You will have to use:
myClass = new MyClass();
myClass.Id = 0;
Hope I made it clear..
Basically, all you have to do is
select ..., (select ... from ... where ...) as ..., ..., from ... where ...
For exemple. You can insert the (select ... from ... where) wherever you want it will be replaced by the corresponding data.
I know that the others exemple (even if each of them are really great :) ) are a bit complicated to understand for the newbies (like me :p) so i hope this "simple" exemple will help some of you guys :)
T = [L[i] for i in Idx]
Actually the list of parameters could be accessed with $1 $2 ...
etc.
Which is exactly equivalent to:
${!i}
So, the list of parameters could be changed with set,
and ${!i}
is the correct way to access them:
$ set -- aa bb cc dd 55 ff gg hh ii jjj kkk lll
$ for ((i=0;i<=$#;i++)); do echo "$#" "$i" "${!i}"; done
12 1 aa
12 2 bb
12 3 cc
12 4 dd
12 5 55
12 6 ff
12 7 gg
12 8 hh
12 9 ii
12 10 jjj
12 11 kkk
12 12 lll
For your specific case, this could be used (without the need for arrays), to set the list of arguments when none was given:
if [ "$#" -eq 0 ]; then
set -- defaultarg1 defaultarg2
fi
which translates to this even simpler expression:
[ "$#" == "0" ] && set -- defaultarg1 defaultarg2

This question is pretty old, so moment.js didn't exist at that time, but for new projects, it simplifies tasks like this a lot.
It's best to parse your date string from UTC as follows (create an ISO-8601 compatible string on the server to get consistent results across all browsers):
var m = moment("2013-02-08T09:30:26Z");
Now just use m
in your application, moment.js defaults to the local timezone for display operations. There are many ways to format the date and time values or extract portions of it.
You can even format a moment object in the users locale like this:
m.format('LLL') // Returns "February 8 2013 8:30 AM" on en-us
To transform a moment.js object into a different timezone (i.e. neither the local one nor UTC), you'll need the moment.js timezone extension. That page has also some examples, it's pretty simple to use.
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
p.kill()
p.kill()
ends up killing the shell process and cmd
is still running.
I found a convenient fix this by:
p = subprocess.Popen("exec " + cmd, stdout=subprocess.PIPE, shell=True)
This will cause cmd to inherit the shell process, instead of having the shell launch a child process, which does not get killed. p.pid
will be the id of your cmd process then.
p.kill()
should work.
I don't know what effect this will have on your pipe though.
deleteInsurance(insuranceId: any) {
const insuranceData = {
id : insuranceId
}
var reqHeader = new HttpHeaders({
"Content-Type": "application/json",
});
const httpOptions = {
headers: reqHeader,
body: insuranceData,
};
return this.http.delete<any>(this.url + "users/insurance", httpOptions);
}
A temporary solution if you don't want to get into the x
, y
position of your title.
Following worked for me.
plt.title('Capital Expenditure\n') # Add a next line after your title
kudos.
In spring servlet .xml :
<context:component-scan base-package="net.controller" />
(I assumed that the service impl is in the same package as the service interface "net.service")
I think you have to add the package net.service (or all of net) to the component scan. Currently spring only searches in net.controller for components and as your service impl is in net.service, it will not be instantiated by spring.
One-liner:
List<Integer> list = Arrays.asList(new Integer[] {1, 2, 3, 4});
The syntax for creating a new table is
CREATE TABLE new_table
AS
SELECT *
FROM old_table
This will create a new table named new_table
with whatever columns are in old_table
and copy the data over. It will not replicate the constraints on the table, it won't replicate the storage attributes, and it won't replicate any triggers defined on the table.
SELECT INTO
is used in PL/SQL when you want to fetch data from a table into a local variable in your PL/SQL block.
Here's an alternate approach to the 'round up' part. Not the most brilliantly coded solution but it gets the job done, and this type of syntax is a bit easier to remember (plus would work for alignment values that aren't a power of 2). The uintptr_t
cast was necessary to appease the compiler; pointer arithmetic isn't very fond of division or multiplication.
void *mem = malloc(1024 + 15);
void *ptr = (void*) ((uintptr_t) mem + 15) / 16 * 16;
memset_16aligned(ptr, 0, 1024);
free(mem);
Look at this page: http://www.webcodingtech.com/javascript/change-cursor.php. Looks like you can access cursor off of style. This page shows it being done with the entire page, but I'm sure a child element would work just as well.
document.body.style.cursor = 'wait';
