drupal_get_destination() has some internal code that points at the correct place to getthe current internal path. To translate that path into an absolute URL, the url() function should do the trick. If the 'absolute' option is passed in it will generate the full URL, not just the internal path. It will also swap in any path aliases for the current path as well.
$path = isset($_GET['q']) ? $_GET['q'] : '<front>';
$link = url($path, array('absolute' => TRUE));
$badData = 'a:2:{i:0;s:16:"as:45:"d";
Is \n";i:1;s:19:"as:45:"d";
Is \r\n";}';
You can not fix a broken serialize string using the proposed regexes:
$data = preg_replace('!s:(\d+):"(.*?)";!e', "'s:'.strlen('$2').':\"$2\";'", $badData);
var_dump(@unserialize($data)); // Output: bool(false)
// or
$data = preg_replace_callback(
'/s:(\d+):"(.*?)";/',
function($m){
return 's:' . strlen($m[2]) . ':"' . $m[2] . '";';
},
$badData
);
var_dump(@unserialize($data)); // Output: bool(false)
You can fix broken serialize string using following regex:
$data = preg_replace_callback(
'/(?<=^|\{|;)s:(\d+):\"(.*?)\";(?=[asbdiO]\:\d|N;|\}|$)/s',
function($m){
return 's:' . strlen($m[2]) . ':"' . $m[2] . '";';
},
$badData
);
var_dump(@unserialize($data));
Output
array(2) {
[0] =>
string(17) "as:45:"d";
Is \n"
[1] =>
string(19) "as:45:"d";
Is \r\n"
}
or
array(2) {
[0] =>
string(16) "as:45:"d";
Is \n"
[1] =>
string(18) "as:45:"d";
Is \r\n"
}
Not sure why this works but dynamic (or wildcard if you prefer) routes are possible in angular 1.2.0-rc.2...
http://code.angularjs.org/1.2.0-rc.2/angular.min.js
http://code.angularjs.org/1.2.0-rc.2/angular-route.min.js
angular.module('yadda', [
'ngRoute'
]).
config(function ($routeProvider, $locationProvider) {
$routeProvider.
when('/:a', {
template: '<div ng-include="templateUrl">Loading...</div>',
controller: 'DynamicController'
}).
controller('DynamicController', function ($scope, $routeParams) {
console.log($routeParams);
$scope.templateUrl = 'partials/' + $routeParams.a;
}).
example.com/foo -> loads "foo" partial
example.com/bar-> loads "bar" partial
No need for any adjustments in the ng-view. The '/:a' case is the only variable I have found that will acheive this.. '/:foo' does not work unless your partials are all foo1, foo2, etc... '/:a' works with any partial name.
All values fire the dynamic controller - so there is no "otherwise" but, I think it is what you're looking for in a dynamic or wildcard routing scenario..
I don't believe this can be done "out of the box" in wordpress; The closest thing is storing media uploads by date-based subfolders, as per the option Organize my uploads into month- and year-based folders on the media settings screen.
Next best might be to create a "dummy" page hierarchy that serves as your folder tree, and then attach your images to these. This would give you a logical grouping, which could exist in relative isolation from your actual page or post hierarchy. But of course this won't give you the files organised like this in the file system, eg you couldn't of course FTP to this structure.
Otherwise I think you'll need to find a plugin or write something yourself to handle this.
Some plugins I found after a quick google for "wordpress plugin media folders":
While these might not be precisely what you want, they might give you clues/direction towards implementing something yourself. (Although that first one looks promising.)
Just FYI at least one similar question has been asked over on Wordpress.stackexchange:
https://wordpress.stackexchange.com/questions/13030/media-library-plugins-for-better-file-management
It might pay to have a good hunt about over there for something more substantial . Good luck!
Try adding the following line in settings.py:
USE_THOUSAND_SEPARATOR = True
This should work.
Refer to documentation.
update at 2018-04-16:
There is also a python way to do this thing:
>>> '{:,}'.format(1000000)
'1,000,000'
I like the extension method solution..
namespace System
{
public static class StringExtensions
{
public static bool TryParseAsEnum<T>(this string value, out T output) where T : struct
{
T result;
var isEnum = Enum.TryParse(value, out result);
output = isEnum ? result : default(T);
return isEnum;
}
}
}
Here below my implementation with tests.
using static Microsoft.VisualStudio.TestTools.UnitTesting.Assert;
using static System.Console;
private enum Countries
{
NorthAmerica,
Europe,
Rusia,
Brasil,
China,
Asia,
Australia
}
[TestMethod]
public void StringExtensions_On_TryParseAsEnum()
{
var countryName = "Rusia";
Countries country;
var isCountry = countryName.TryParseAsEnum(out country);
WriteLine(country);
IsTrue(isCountry);
AreEqual(Countries.Rusia, country);
countryName = "Don't exist";
isCountry = countryName.TryParseAsEnum(out country);
WriteLine(country);
IsFalse(isCountry);
AreEqual(Countries.NorthAmerica, country); // the 1rst one in the enumeration
}
For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
While this will not (note the leading space before the opening <?
tag)
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Also, this will not work either (the echo
will break it):
<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.
add ob_start ();
at the top and at the end add ob_end_flush();
<?php
ob_start();
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
ob_end_flush();
?>
give me an error as below:
FPDF error: Some data has already been output, can't send PDF
to over come this error:
go to fpdf.php
in that,goto line number 996
function Output($name='', $dest='')
after that make changes like this:
function Output($name='', $dest='') {
ob_clean(); //Output PDF to so
Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.
<?
while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);
?>
cheers :-)
In my case i had set:
ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);
When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off
the display_errors
option, the report was generated successfully.
Use the ref
keyword.
Look at the definitive reference here to understand passing parameters.
To be specific, look at this, to understand the behavior of the code.
EDIT: Sort
works on the same reference (that is passed by value) and hence the values are ordered. However, assigning a new instance to the parameter won't work because parameter is passed by value, unless you put ref
.
Putting ref
lets you change the pointer to the reference to a new instance of List
in your case. Without ref
, you can work on the existing parameter, but can't make it point to something else.
For a slightly cleaner way to do it, try:
<div>
{React.cloneElement(this.props.children, { loggedIn: this.state.loggedIn })}
</div>
Edit: To use with multiple individual children (the child must itself be a component) you can do. Tested in 16.8.6
<div>
{React.cloneElement(this.props.children[0], { loggedIn: true, testPropB: true })}
{React.cloneElement(this.props.children[1], { loggedIn: true, testPropA: false })}
</div>
The behavior exact to the one specified by you is impossible in JS as implemented in current browsers. Sorry.
Well, you could in theory make a function with a loop where loop's end condition would be based on time, but this would hog your CPU, make browser unresponsive and would be extremely poor design. I refuse to even write an example for this ;)
Update: My answer got -1'd (unfairly), but I guess I could mention that in ES6 (which is not implemented in browsers yet, nor is it enabled in Node.js by default), it will be possible to write a asynchronous code in a synchronous fashion. You would need promises and generators for that.
You can use it today, for instance in Node.js with harmony flags, using Q.spawn(), see this blog post for example (last example there).
There is no real speed difference. They are really all the same to the compiler. The difference is with the human beings trying to use and read your code.
For me that makes bool, true, and false the best choice in C++ code. In C code, there are some compilers around that don't support bool (I often have to work with old systems), so I might go with the defines in some circumstances.
Java ships in 2 versions: JRE & SDK (used to be called JDK)
The JRE in addition to not containing the compiler, also doesn't contain all of the libraries available in the JDK (tools.jar is one of them)
When you download Java at: http://java.sun.com/javase/downloads/index.jsp, make sure to select the JDK version and install it. If you have both a JDK & JRE, make sure that ANT is using the JDK, you can check JAVA_HOME (environment variable), and on the commandline if you do "javac -version" you should get a version description.
Set them so that their flex-basis
is 0
(so all elements have the same starting point), and allow them to grow:
flex: 1 1 0px
Your IDE or linter might mention that the unit of measure 'px' is redundant
. If you leave it out (like: flex: 1 1 0
), IE will not render this correctly. So the px
is required to support Internet Explorer, as mentioned in the comments by @fabb;

You should use the "siblings()" method, and prevent from running the ".content a" selector over and over again just for applying that effect:
HTML
<div class="content">
<a href="#">A</a>
</div>
<div class="content">
<a href="#">B</a>
</div>
<div class="content">
<a href="#">C</a>
</div>
CSS
.content {
background-color:red;
margin:10px;
}
.content.other {
background-color:yellow;
}
Javascript
$(".content a").click(function() {
var current = $(this).parent();
current.removeClass('other')
.siblings()
.addClass('other');
});
See here: http://jsfiddle.net/3bzLV/1/
If your 13 digit "number" is really text, that is you don't intend to do any math on it, you can precede it with an apostrophe
Sheet3.Range("c" & k).Value = "'" & Sheet2.Range("c" & i).Value
But I don't see how a 13 digit number would ever get past the If statement because it would always be greater than 1000. Here's an alternate version
Sub CommandClick()
Dim rCell As Range
Dim rNext As Range
For Each rCell In Sheet2.Range("C1:C30000").Cells
If rCell.Value >= 100 And rCell.Value < 1000 Then
Set rNext = Sheet3.Cells(Sheet3.Rows.Count, 1).End(xlUp).Offset(1, 0)
rNext.Resize(1, 3).Value = rCell.Offset(0, -2).Resize(1, 3).Value
End If
Next rCell
End Sub
While @Timar's answer works perfectly for null
default values (what was asked for), here another easy solution which allows other default values: Define an option interface as well as an according constant containing the defaults; in the constructor use the spread operator to set the options
member variable
interface IXOptions {
a?: string,
b?: any,
c?: number
}
const XDefaults: IXOptions = {
a: "default",
b: null,
c: 1
}
export class ClassX {
private options: IXOptions;
constructor(XOptions: IXOptions) {
this.options = { ...XDefaults, ...XOptions };
}
public printOptions(): void {
console.log(this.options.a);
console.log(this.options.b);
console.log(this.options.c);
}
}
Now you can use the class like this:
const x = new ClassX({ a: "set" });
x.printOptions();
Output:
set
null

The more general answer is
UPDATE mysql.user SET host = {newhost} WHERE user = {youruser}
Try this:
SELECT name, email
FROM users
GROUP BY name, email
HAVING ( COUNT(*) > 1 )
form.onsubmit will always be a function when defined as an attribute of HTML the form element. It's some sort of anonymous function attached to an HTML element, which has the this pointer bound to that FORM element and also has a parameter named event
which will contain data about the submit event.
Under these circumstances I don't understand how you got a string as a result of a typeof operation. You should give more details, better some code.
Edit (as a response to your second edit):
I believe the handler attached to the HTML attribute will execute regardless of the above code. Further more, you could try to stop it somehow, but, it appears that FF 3, IE 8, Chrome 2 and Opera 9 are executing the HTML attribute handler in the first place and then the one attached (I didn't tested with jQuery though, but with addEventListener and attachEvent). So... what are you trying to accomplish exactly?
By the way, your code isn't working because your regular expression will extract the string "valid();", which is definitely not a function.
Add which files you want to ignore to file .gitignore
:
*.class
*.projects
*.prefs
*.project
Try this
SELECT
object_name(parent_object_id) ParentTableName,
object_name(referenced_object_id) RefTableName,
name
FROM sys.foreign_keys
WHERE parent_object_id = object_id('Tablename')
As the more recent MySQL documentation on view restrictions says:
Before MySQL 5.7.7, subqueries cannot be used in the FROM clause of a view.
This means, that choosing a MySQL v5.7.7 or newer or upgrading the existing MySQL instance to such a version, would remove this restriction on views completely.
However, if you have a current production MySQL version that is earlier than v5.7.7, then the removal of this restriction on views should only be one of the criteria being assessed while making a decision as to upgrade or not. Using the workaround techniques described in the other answers may be a more viable solution - at least on the shorter run.
Both are of same concept but in atomic boolean it will provide atomicity to the operation in case the cpu switch happens in between.
I just shortened the answer I selected a bit:
var selectedGroups = new Array();
$("input[@name='user_group[]']:checked").each(function() {
selectedGroups.push($(this).val());
});
and it works like a charm, thanks!
The regular expression in the question misses a lot of edge cases. When detecting URLs, it's always better to use a specialized library that handles international domain names, new TLDs like .museum
, parentheses and other punctuation within and at the end of the URL, and many other edge cases. See the Jeff Atwood's blog post The Problem With URLs for an explanation of some of the other issues.
The best summary of URL matching libraries is in Dan Dascalescu's Answer
(as of Feb 2014)
Add a "g" to the end of the regular expression to enable global matching:
/ig;
But that only fixes the problem in the question where the regular expression was only replacing the first match. Do not use that code.
oninput
event is very useful to track input fields changes.
However it is not supported in IE version < 9. But older IE versions has its own proprietary event onpropertychange
that does the same as oninput
.
So you can use it this way:
$(':input').on('input propertychange');
To have a full crossbrowser support.
Since the propertychange can be triggered for ANY property change, for example, the disabled property is changed, then you want to do include this:
$(':input').on('propertychange input', function (e) {
var valueChanged = false;
if (e.type=='propertychange') {
valueChanged = e.originalEvent.propertyName=='value';
} else {
valueChanged = true;
}
if (valueChanged) {
/* Code goes here */
}
});
I use the ffmpeg-python
binding. You can find more information here.

.run()
)
Check this code based on the article Geo-Distance-Search-with-MySQL:
Example: find the 10 nearest hotels to my current location in a 10 miles radius:
#Please notice that (lat,lng) values mustn't be negatives to perform all calculations
set @my_lat=34.6087674878572;
set @my_lng=58.3783670308302;
set @dist=10; #10 miles radius
SELECT dest.id, dest.lat, dest.lng, 3956 * 2 * ASIN(SQRT(POWER(SIN((@my_lat -abs(dest.lat)) * pi()/180 / 2),2) + COS(@my_lat * pi()/180 ) * COS(abs(dest.lat) * pi()/180) * POWER(SIN((@my_lng - abs(dest.lng)) * pi()/180 / 2), 2))
) as distance
FROM hotel as dest
having distance < @dist
ORDER BY distance limit 10;
#Also notice that distance are expressed in terms of radius.
Take a look at your code :
getUsers(): Observable<User[]> {
return Observable.create(observer => {
this.http.get('http://users.org').map(response => response.json();
})
}
and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)
getHeroes(): Promise<Hero[]> {
return this.http.get(this.heroesUrl)
.toPromise()
.then(response => response.json().data as Hero[])
.catch(this.handleError);
}
The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:
return Observable.create(observer => {
this.http.get('http://users.org').map(response => response.json()
Try to follow the guide in link that I provided. You should be just fine when you study it carefully.
---EDIT----
First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!
Try to do it like this:
getUsers(): void {
this.userService.getUsers()
.then(users => {
this.users = users
console.log('this.users=' + this.users);
});
}
See where the console.log(...) is!
Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.
Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.
The following statement causes a user's password to expire:
ALTER USER user PASSWORD EXPIRE;
If you cause a database user's password to expire with PASSWORD EXPIRE, then the user (or the DBA) must change the password before attempting to log in to the database following the expiration. Tools such as SQL*Plus allow the user to change the password on the first attempted login following the expiration.
ALTER USER scott IDENTIFIED BY password;
Will set/reset the users password.
See the alter user doc for more info

You should never add credentials to a container unless you're OK broadcasting the creds to whomever can download the image. In particular, doing and ADD creds
and later RUN rm creds
is not secure because the creds file remains in the final image in an intermediate filesystem layer. It's easy for anyone with access to the image to extract it.
The typical solution I've seen when you need creds to checkout dependencies and such is to use one container to build another. I.e., typically you have some build environment in your base container and you need to invoke that to build your app container. So the simple solution is to add your app source and then RUN
the build commands. This is insecure if you need creds in that RUN
. Instead what you do is put your source into a local directory, run (as in docker run
) the container to perform the build step with the local source directory mounted as volume and the creds either injected or mounted as another volume. Once the build step is complete you build your final container by simply ADD
ing the local source directory which now contains the built artifacts.
I'm hoping Docker adds some features to simplify all this!
Update: looks like the method going forward will be to have nested builds. In short, the dockerfile would describe a first container that is used to build the run-time environment and then a second nested container build that can assemble all the pieces into the final container. This way the build-time stuff isn't in the second container. This of a Java app where you need the JDK for building the app but only the JRE for running it. There are a number of proposals being discussed, best to start from https://github.com/docker/docker/issues/7115 and follow some of the links for alternate proposals.
Below is another method to import spreadsheet data into a MySQL database that doesn't rely on any extra software. Let's assume you want to import your Excel table into the sales
table of a MySQL database named mydatabase
.
Select the relevant cells:
Paste into Mr. Data Converter and select the output as MySQL:
Change the table name and column definitions to fit your requirements in the generated output:
CREATE TABLE sales (
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
Country VARCHAR(255),
Amount INT,
Qty FLOAT
);
INSERT INTO sales
(Country,Amount,Qty)
VALUES
('America',93,0.60),
('Greece',9377,0.80),
('Australia',9375,0.80);
If you're using MySQL Workbench or already logged into mysql
from the command line, then you can execute the generated SQL statements from step 3 directly. Otherwise, paste the code into a text file (e.g., import.sql
) and execute this command from a Unix shell:
mysql mydatabase < import.sql
Other ways to import from a SQL file can be found in this Stack Overflow answer.
Try this:
select * from all_constraints where r_constraint_name in (select constraint_name
from all_constraints where table_name='YOUR_TABLE_NAME');
You are just using a single parameter inside the function hence it is working fine in both the cases like follows:
MsgBox "Hello world!"
MsgBox ("Hello world!")
But when you'll use more than one parameter, In VBScript method will parenthesis will throw an error and without parenthesis will work fine like:
MsgBox "Hello world!", vbExclamation
The above code will run smoothly but
MsgBox ("Hello world!", vbExclamation)
will throw an error. Try this!! :-)
Glob function doesn't return the hidden files, therefore scandir can be more useful, when trying to delete recursively a tree.
<?php
public static function delTree($dir) {
$files = array_diff(scandir($dir), array('.','..'));
foreach ($files as $file) {
(is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file");
}
return rmdir($dir);

This is where regular expressions come in handy! Javascript's .replace()
method will take a regular expression, and you can utilize that to accomplish what you want:
// assuming var x = filename.jpg or some extension
x = x.replace(/(.*)\.[^.]+$/, "$1");
I'd explain parsing as the process of turning some kind of data into another kind of data.
In practice, for me this is almost always turning a string, or binary data, into a data structure inside my Program.
For example, turning
":Nick!User@Host PRIVMSG #channel :Hello!"
into (C)
struct irc_line {
char *nick;
char *user;
char *host;
char *command;
char **arguments;
char *message;
} sample = { "Nick", "User", "Host", "PRIVMSG", { "#channel" }, "Hello!" }
Be sure to have both objects created in controller: @post
and @comment
for the post, eg:
@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)
Then in view:
<%= form_for([@post, @comment]) do |f| %>
Be sure to explicitly define the array in the form_for, not just comma separated like you have above.
These terms are unfortunately overloaded with several possible definitions. According to the ANSI-SPARC "three schema" model for instance, the Conceptual Schema or Conceptual Model consists of the set of objects in a database (tables, views, etc) in contrast to the External Schema which are the objects that users see.
In the data management professions and especially among data modellers / architects, the term Conceptual Model is frequently used to mean a semantic model whereas the term Logical Model is used to mean a preliminary or virtual database design. This is probably the usage you are most likely to come across in the workplace.
In academic usage and when describing DBMS architectures however, the Logical level means the database objects (tables, views, tables, keys, constraints, etc), as distinct from the Physical level (files, indexes, storage). To confuse things further, in the workplace the term Physical model is often used to mean the design as implemented or planned for implementation in an actual database. That may include both "physical" and "logical" level constructs (both tables and indexes for example).
When you come across any of these terms you really need to seek clarification on what is being described unless the context makes it obvious.
For a discussion of these differences, check out Data Modelling Essentials by Simsion and Witt for example.
The ssl
module is a TLS/SSL wrapper for accessing Operation Sytem (OS) socket (Lib/ssl.py). So when ssl
module is not available, chances are that you either don't have OS OpenSSL libraries installed, or those libraries were not found when you install Python. Let assume it is a later case (aka: you already have OpenSSL installed, but they are not correctly linked when installing Python).
I will also assume you are installing from source. If you are installing from binary (ie: Window .exe file), or package (Mac .dmg, or Ubuntu apt), there is not much you can do with the installing process.
During the step of configuring your python installation, you need to specify where the OS OpenSSL will be used for linking:
# python 3.8 beta
./configure --with-openssl="your_OpenSSL root"
So where will you find your installed OpenSSL directory?
# ubuntu
locate ssl.h | grep '/openssl/ssl.h'
/home/user/.linuxbrew/Cellar/openssl/1.0.2r/include/openssl/ssl.h
/home/user/envs/py37/include/openssl/ssl.h
/home/user/miniconda3/envs/py38b3/include/openssl/ssl.h
/home/user/miniconda3/include/openssl/ssl.h
/home/user/miniconda3/pkgs/openssl-1.0.2s-h7b6447c_0/include/openssl/ssl.h
/home/user/miniconda3/pkgs/openssl-1.1.1b-h7b6447c_1/include/openssl/ssl.h
/home/user/miniconda3/pkgs/openssl-1.1.1c-h7b6447c_1/include/openssl/ssl.h
/usr/include/openssl/ssl.h
Your system may be different than mine, but as you see here I have many different installed openssl libraries. As the time of this writing, python 3.8 expects openssl 1.0.2 or 1.1:
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
So you would need to verify which of those installed libraries that you can use for linking, for example
/usr/bin/openssl version
OpenSSL 1.0.2g 1 Mar 2016
./configure --with-openssl="/usr"
make && make install
You may need to try a few, or install a new, to find the library that would work for your Python and your OS.
In addition to Marty's excellent Answer, the SystemVerilog specification offers the byte
data type. The following declares a 4x8-bit variable (4 bytes), assigns each byte a value, then displays all values:
module tb;
byte b [4];
initial begin
foreach (b[i]) b[i] = 1 << i;
foreach (b[i]) $display("Address = %0d, Data = %b", i, b[i]);
$finish;
end
endmodule
This prints out:
Address = 0, Data = 00000001
Address = 1, Data = 00000010
Address = 2, Data = 00000100
Address = 3, Data = 00001000
This is similar in concept to Marty's reg [7:0] a [0:3];
. However, byte
is a 2-state data type (0 and 1), but reg
is 4-state (01xz). Using byte
also requires your tool chain (simulator, synthesizer, etc.) to support this SystemVerilog syntax. Note also the more compact foreach (b[i])
loop syntax.
The SystemVerilog specification supports a wide variety of multi-dimensional array types. The LRM can explain them better than I can; refer to IEEE Std 1800-2005, chapter 5.
When creating an array like that, its size must be constant. If you want a dynamically sized array, you need to allocate memory for it on the heap and you'll also need to free it with delete
when you're done:
//allocate the array
int** arr = new int*[row];
for(int i = 0; i < row; i++)
arr[i] = new int[col];
// use the array
//deallocate the array
for(int i = 0; i < row; i++)
delete[] arr[i];
delete[] arr;
If you want a fixed size, then they must be declared const:
const int row = 8;
const int col = 8;
int arr[row][col];
Also,
int [row][col];
doesn't even provide a variable name.
Using bash:
if [ "`mysql -u'USER' -p'PASSWORD' -se'USE $DATABASE_NAME;' 2>&1`" == "" ]; then
echo $DATABASE_NAME exist
else
echo $DATABASE_NAME doesn't exist
fi
I think 100% correct conversion isn't possible, if the value comes from a user input. e.g. if the value is 123.456, it can be a grouping or it can be a decimal point. If you really need 100% you have to describe your format and throw an exception if it is not correct.
But I improved the code of JanW, so we get a little bit more ahead to the 100%. The idea behind is, that if the last separator is a groupSeperator, this would be more an integer type, than a double.
The added code is in the first if of GetDouble.
void Main()
{
List<string> inputs = new List<string>() {
"1.234.567,89",
"1 234 567,89",
"1 234 567.89",
"1,234,567.89",
"1234567,89",
"1234567.89",
"123456789",
"123.456.789",
"123,456,789,"
};
foreach(string input in inputs) {
Console.WriteLine(GetDouble(input,0d));
}
}
public static double GetDouble(string value, double defaultValue) {
double result;
string output;
// Check if last seperator==groupSeperator
string groupSep = System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberGroupSeparator;
if (value.LastIndexOf(groupSep) + 4 == value.Count())
{
bool tryParse = double.TryParse(value, System.Globalization.NumberStyles.Any, System.Globalization.CultureInfo.CurrentCulture, out result);
result = tryParse ? result : defaultValue;
}
else
{
// Unify string (no spaces, only . )
output = value.Trim().Replace(" ", string.Empty).Replace(",", ".");
// Split it on points
string[] split = output.Split('.');
if (split.Count() > 1)
{
// Take all parts except last
output = string.Join(string.Empty, split.Take(split.Count()-1).ToArray());
// Combine token parts with last part
output = string.Format("{0}.{1}", output, split.Last());
}
// Parse double invariant
result = double.Parse(output, System.Globalization.CultureInfo.InvariantCulture);
}
return result;
}
Just create a multi-line comment around it. When you want it back, just erase the comment tags.
For example, <!-- Stuff to comment out or make inactive -->
You can simply use,
import json
json.loads(my_bytes_value)
Your BlockID
function uses the undefined variable images
, which will lead to an error. Also, you should not use an Array
here - JavaScripts key-value-maps are plain objects:
function BlockID() {
return {
"s": "Images/Block_01.png",
"g": "Images/Block_02.png",
"C": "Images/Block_03.png",
"d": "Images/Block_04.png"
};
}
People mentioned string.find()
, string.index()
, and string.indexOf()
in the comments, and I summarize them here (according to the Python Documentation):
First of all there is not a string.indexOf()
method. The link posted by Deviljho shows this is a JavaScript function.
Second the string.find()
and string.index()
actually return the index of a substring. The only difference is how they handle the substring not found situation: string.find()
returns -1
while string.index()
raises an ValueError
.
I'm not convinced its a good idea to return image data in a REST service. It ties up your application server's memory and IO bandwidth. Much better to delegate that task to a proper web server that is optimized for this kind of transfer. You can accomplish this by sending a redirect to the image resource (as a HTTP 302 response with the URI of the image). This assumes of course that your images are arranged as web content.
Having said that, if you decide you really need to transfer image data from a web service you can do so with the following (pseudo) code:
@Path("/whatever")
@Produces("image/png")
public Response getFullImage(...) {
BufferedImage image = ...;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(image, "png", baos);
byte[] imageData = baos.toByteArray();
// uncomment line below to send non-streamed
// return Response.ok(imageData).build();
// uncomment line below to send streamed
// return Response.ok(new ByteArrayInputStream(imageData)).build();
}
Add in exception handling, etc etc.
You may have not set the output file.
I ended up overriding Fragment.onResume()
and grabbing the attributes from the underlying dialog, then setting width/height params there. I set the outermost layout height/width to match_parent
. Note that this code seems to respect the margins I defined in the xml layout as well.
@Override
public void onResume() {
super.onResume();
ViewGroup.LayoutParams params = getDialog().getWindow().getAttributes();
params.width = LayoutParams.MATCH_PARENT;
params.height = LayoutParams.MATCH_PARENT;
getDialog().getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}
var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth();
var curr_year = d.getFullYear();
curr_year = curr_year.toString().substr(2,2);
document.write(curr_date+"-"+curr_month+"-"+curr_year);
You can change this as your need..
You may find these questions helpful:
Google is your friend - first hit - also you might first have a look at what serialization is.
It marks a member variable not to be serialized when it is persisted to streams of bytes. When an object is transferred through the network, the object needs to be 'serialized'. Serialization converts the object state to serial bytes. Those bytes are sent over the network and the object is recreated from those bytes. Member variables marked by the java transient keyword are not transferred, they are lost intentionally.
Example from there, slightly modified (thanks @pgras):
public class Foo implements Serializable
{
private String saveMe;
private transient String dontSaveMe;
private transient String password;
//...
}
The 'go to bracket' shortcut takes cursor before the bracket, unlike the 'end' key which takes after the bracket. WASDMap VSCode extension is very helpful for navigating and selecting text using WASD keys.
The above answers won't let you quote inside the quotes. This solution will:
sudo -su nobody umask 0000 \; mkdir -p "$targetdir"
Both the umask command and the mkdir-command runs in with the 'nobody' user.
The Observable object represents a push based collection.
The Observer and Observable interfaces provide a generalized mechanism for push-based notification, also known as the observer design pattern. The Observable object represents the object that sends notifications (the provider); the Observer object represents the class that receives them (the observer).
The Subject class inherits both Observable and Observer, in the sense that it is both an observer and an observable. You can use a subject to subscribe all the observers, and then subscribe the subject to a backend data source
var subject = new Rx.Subject();
var subscription = subject.subscribe(
function (x) { console.log('onNext: ' + x); },
function (e) { console.log('onError: ' + e.message); },
function () { console.log('onCompleted'); });
subject.onNext(1);
// => onNext: 1
subject.onNext(2);
// => onNext: 2
subject.onCompleted();
// => onCompleted
subscription.dispose();

<?php
if(!@mysql_connect('127.0.0.1', 'root', '*your default password*'))
{
echo "mysql not connected ".mysql_error();
exit;
}
echo 'great work';
?>
if no error then you will get greatwork as output.
Try it saved my life XD XD
To complement Michael's answer, and according to this answer, a safe way to deal with the problem is to use the following arguments:
-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UseConcMarkSweepGC
When the session expires the data is no longer present, so something like
if (!isset($_SESSION['id'])) {
header("Location: destination.php");
exit;
}
will redirect whenever the session is no longer active.
You can set how long the session cookie is alive using session.cookie_lifetime
ini_set("session.cookie_lifetime","3600"); //an hour
EDIT: If you are timing sessions out due to security concern (instead of convenience,) use the accepted answer, as the comments below show, this is controlled by the client and thus not secure. I never thought of this as a security measure.
Try this, it will surely work:
driver.findElement(By.xpath("//label[text()='User Name:']/following::div/input")).sendKeys("UserName" + Keys.TAB);
I use the following rake task to override the Rails drop_database
method.
lib/database.rake
require 'active_record/connection_adapters/postgresql_adapter'
module ActiveRecord
module ConnectionAdapters
class PostgreSQLAdapter < AbstractAdapter
def drop_database(name)
raise "Nah, I won't drop the production database" if Rails.env.production?
execute <<-SQL
UPDATE pg_catalog.pg_database
SET datallowconn=false WHERE datname='#{name}'
SQL
execute <<-SQL
SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = '#{name}';
SQL
execute "DROP DATABASE IF EXISTS #{quote_table_name(name)}"
end
end
end
end
Edit: This is for Postgresql 9.2+
According to the spec RFC 2045 #Syntax of the Content-Type Header Field application/myappname
is not allowed, but application/x-myappname
is allowed and sounds most appropriate for you're application to me.
Yes I use gocr at http://jocr.sourceforge.net/ its a commandline application which you could execute from your application. I use it in a couple of my applications.
My solution handles quotes, overriding field and string separators, etc. It is short and sweet.
public static string[] CSVRowToStringArray(string r, char fieldSep = ',', char stringSep = '\"')
{
bool bolQuote = false;
StringBuilder bld = new StringBuilder();
List<string> retAry = new List<string>();
foreach (char c in r.ToCharArray())
if ((c == fieldSep && !bolQuote))
{
retAry.Add(bld.ToString());
bld.Clear();
}
else
if (c == stringSep)
bolQuote = !bolQuote;
else
bld.Append(c);
return retAry.ToArray();
}
The breakdown of your declaration and its members is somewhat littered:
Remove the typedef
The typedef
is neither required, not desired for class/struct declarations in C++. Your members have no knowledge of the declaration of pos
as-written, which is core to your current compilation failure.
Change this:
typedef struct {....} pos;
To this:
struct pos { ... };
Remove extraneous inlines
You're both declaring and defining your member operators within the class definition itself. The inline
keyword is not needed so long as your implementations remain in their current location (the class definition)
Return references to *this
where appropriate
This is related to an abundance of copy-constructions within your implementation that should not be done without a strong reason for doing so. It is related to the expression ideology of the following:
a = b = c;
This assigns c
to b
, and the resulting value b
is then assigned to a
. This is not equivalent to the following code, contrary to what you may think:
a = c;
b = c;
Therefore, your assignment operator should be implemented as such:
pos& operator =(const pos& a)
{
x = a.x;
y = a.y;
return *this;
}
Even here, this is not needed. The default copy-assignment operator will do the above for you free of charge (and code! woot!)
Note: there are times where the above should be avoided in favor of the copy/swap idiom. Though not needed for this specific case, it may look like this:
pos& operator=(pos a) // by-value param invokes class copy-ctor
{
this->swap(a);
return *this;
}
Then a swap method is implemented:
void pos::swap(pos& obj)
{
// TODO: swap object guts with obj
}
You do this to utilize the class copy-ctor to make a copy, then utilize exception-safe swapping to perform the exchange. The result is the incoming copy departs (and destroys) your object's old guts, while your object assumes ownership of there's. Read more the copy/swap idiom here, along with the pros and cons therein.
Pass objects by const reference when appropriate
All of your input parameters to all of your members are currently making copies of whatever is being passed at invoke. While it may be trivial for code like this, it can be very expensive for larger object types. An exampleis given here:
Change this:
bool operator==(pos a) const{
if(a.x==x && a.y== y)return true;
else return false;
}
To this: (also simplified)
bool operator==(const pos& a) const
{
return (x == a.x && y == a.y);
}
No copies of anything are made, resulting in more efficient code.
Finally, in answering your question, what is the difference between a member function or operator declared as const
and one that is not?
A const
member declares that invoking that member will not modifying the underlying object (mutable declarations not withstanding). Only const
member functions can be invoked against const
objects, or const
references and pointers. For example, your operator +()
does not modify your local object and thus should be declared as const
. Your operator =()
clearly modifies the local object, and therefore the operator should not be const
.
Summary
struct pos
{
int x;
int y;
// default + parameterized constructor
pos(int x=0, int y=0)
: x(x), y(y)
{
}
// assignment operator modifies object, therefore non-const
pos& operator=(const pos& a)
{
x=a.x;
y=a.y;
return *this;
}
// addop. doesn't modify object. therefore const.
pos operator+(const pos& a) const
{
return pos(a.x+x, a.y+y);
}
// equality comparison. doesn't modify object. therefore const.
bool operator==(const pos& a) const
{
return (x == a.x && y == a.y);
}
};
EDIT OP wanted to see how an assignment operator chain works. The following demonstrates how this:
a = b = c;
Is equivalent to this:
b = c;
a = b;
And that this does not always equate to this:
a = c;
b = c;
Sample code:
#include <iostream>
#include <string>
using namespace std;
struct obj
{
std::string name;
int value;
obj(const std::string& name, int value)
: name(name), value(value)
{
}
obj& operator =(const obj& o)
{
cout << name << " = " << o.name << endl;
value = (o.value+1); // note: our value is one more than the rhs.
return *this;
}
};
int main(int argc, char *argv[])
{
obj a("a", 1), b("b", 2), c("c", 3);
a = b = c;
cout << "a.value = " << a.value << endl;
cout << "b.value = " << b.value << endl;
cout << "c.value = " << c.value << endl;
a = c;
b = c;
cout << "a.value = " << a.value << endl;
cout << "b.value = " << b.value << endl;
cout << "c.value = " << c.value << endl;
return 0;
}
Output
b = c
a = b
a.value = 5
b.value = 4
c.value = 3
a = c
b = c
a.value = 4
b.value = 4
c.value = 3
Splitting by comma doesn't work all the time for instance if you have csv file like
"Name" , "Job" , "Address"
"Pratiyush, Singh" , "Teacher" , "Berlin, Germany"
So, I would recommend using the Apache Commons CSV API:
Reader in = new FileReader("input1.csv");
Iterable<CSVRecord> records = CSVFormat.EXCEL.parse(in);
for (CSVRecord record : records) {
System.out.println(record.get(0));
}
We have resolved the circular dependency(Parent-child Entities) by mapping the child entity instead of parent entity in Grails 4(GORM).
Example:
Class Person {
String name
}
Class Employee extends Person{
String empId
}
//Before my code
Class Address {
static belongsTo = [person: Person]
}
//We changed our Address class to:
Class Address {
static belongsTo = [person: Employee]
}
The problem is the import of ProjectsListComponent
in your ProjectsModule
. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule
.
Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule
anywhere else but in your AppModule
. Use the CommonModule
to get access to the *ngIf, *ngFor...etc
directives:
@NgModule({
declarations: [
ProjectsListComponent
],
imports: [
CommonModule,
RouterModule.forChild(ProjectRoutes)
],
exports: [
ProjectsListComponent
]
})
export class ProjectsModule {}
project.routes.ts
export const ProjectRoutes: Routes = [
{ path: 'projects', component: ProjectsListComponent }
]
Here is a functional approach using map
, itertools.repeat
and operator.mul
:
import operator
from itertools import repeat
def scalar_multiplication(vector, scalar):
yield from map(operator.mul, vector, repeat(scalar))
Example of usage:
>>> v = [1, 2, 3, 4]
>>> c = 3
>>> list(scalar_multiplication(v, c))
[3, 6, 9, 12]
Please follow the below steps
1). First, navigate to the /etc/postgresql/{your pg version}/main directory.
My version is 10 Then:
cd /etc/postgresql/10/main
2). Here resides the pg_hba.conf file needs to do some changes here you may need sudo access for this.
sudo nano pg_hba.conf
3). Scroll down the file till you find this –
# Database administrative login by Unix domain socket
local all postgres peer
4). Here change the peer to md5 as follows.
# Database administrative login by Unix domain socket
local all all md5
peer means it will trust the authenticity of UNIX user hence does not
prompt for the password. md5 means it will always ask for a password, and validate it after hashing with MD5.
5).Now save the file and restart the Postgres server.
sudo service postgresql restart
Now it should be ok.
I did test your code and the only problem I could see was the lack of permission given to the directory you try to write the file in to.
Give "write" permission to the directory you need to put the file. In your case it is the current directory.
Use "chmod" in linux.
Add "Everyone" with "write" enabled to the security tab of the directory if you are in Windows.
I have fixed this problem for myself as follows.
First of all, I followed the other answers for this question, only to conclude that all the project settings were correct.
Then I inspected the .vcxproj file with an editor and noticed that the < Link > properties for the two (Debug and Release) x64 configurations did not specify < TargetMachine >, while the Win32 configurations both contained < TargetMachine > MachineX86 < /TargetMachine >.
However, I had already verified, looking from Visual Studio at Properties > Configuration Properties > Linker > Advanced > Target Machine, that the x64 configurations said MachineX64 (/MACHINE:X64).
So, I edited the .vcxproj file to include < TargetMachine > MachineX64 < /TargetMachine > in the two x64 configs. Going back to the Visual Studio project properties dialog, I noticed that the MachineX64 (/MACHINE:X64) setting was there as before, except that now it showed in bold (apparently meaning that the value is not the default one).
I rebuilt, and it worked.
<select>
<option selected="selected" class="Country">Country Name</option>

I found a very good answer here which explains when to use what in simple words:
The basic rule of thumb for which framework to use is how to plan on editing your data in your presentation layer.
Linq-To-Sql - use this framework if you plan on editing a one-to-one relationship of your data in your presentation layer. Meaning you don't plan on combining data from more than one table in any one view or page.
Entity Framework - use this framework if you plan on combining data from more than one table in your view or page. To make this clearer, the above terms are specific to data that will be manipulated in your view or page, not just displayed. This is important to understand.
With the Entity Framework you are able to "merge" tabled data together to present to the presentation layer in an editable form, and then when that form is submitted, EF will know how to update ALL the data from the various tables.
There are probably more accurate reasons to choose EF over L2S, but this would probably be the easiest one to understand. L2S does not have the capability to merge data for view presentation.
Their is a tool called indent
. You can download it with apt-get install indent
, then run indent my_program.c
.
Quite and simple without any "having to specify the first element". CSS is more powerful than most think (e.g. the first-child:before
is great!). But this is by far the cleanest and most proper way to do this, at least in my opinion it is.
#navigation ul
{
margin: 0;
padding: 0;
}
#navigation ul li
{
list-style-type: none;
display: inline;
}
#navigation li:not(:first-child):before {
content: " | ";
}
Now just use a simple unordered list in HTML and it'll populate it for you. HTML should look like this:
<div id="navigation">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">About Us</a></li>
<li><a href="#">Support</a></li>
</ul>
</div><!-- navigation -->
The result will be just like this:
HOME | ABOUT US | SUPPORT
Now you can indefinitely expand and never have to worry about order, changing links, or your first entry. It's all automated and works great!
I had this issue during VBA development/debugging suddenly because some (unknown to me) function(ality) caused the cells to be locked (maybe renaming of named references at some problematic stage).
Unlocking the cells manually worked fine:
Selecting all worksheet cells (CTRL+A
) and unlock by right click -> cell formatting -> protection -> [ ] lock
(may be different - translated from German: Zellen formatieren -> Schutz -> [ ] Gesperrt
)
Another option would be file_get_contents()
:
// $xml_str = your xml
// $url = target url
$post_data = array('xml' => $xml_str);
$stream_options = array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded' . "\r\n",
'content' => http_build_query($post_data)));
$context = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);
Once again, please wait for a while, sometimes you missed that it actually worked but you are feeling really stressed and could not wait(I was).
Not sure why I fixed the same issue that happened on my Macbook, however, choose Nexus 5X API R would work somehow. OR below

From nullptr: A Type-safe and Clear-Cut Null Pointer:
The new C++09 nullptr keyword designates an rvalue constant that serves as a universal null pointer literal, replacing the buggy and weakly-typed literal 0 and the infamous NULL macro. nullptr thus puts an end to more than 30 years of embarrassment, ambiguity, and bugs. The following sections present the nullptr facility and show how it can remedy the ailments of NULL and 0.

For those still reading this answer, if you are using ES6 the find
method was added in arrays. So assuming the same collection, the solution'd be:
const foo = { "results": [
{
"id": 12,
"name": "Test"
},
{
"id": 2,
"name": "Beispiel"
},
{
"id": 3,
"name": "Sample"
}
] };
foo.results.find(item => item.id === 2)
I'd totally go for this solution now, as is less tied to angular or any other framework. Pure Javascript.
Angular solution (old solution)
I aimed to solve this problem by doing the following:
$filter('filter')(foo.results, {id: 1})[0];
A use case example:
app.controller('FooCtrl', ['$filter', function($filter) {
var foo = { "results": [
{
"id": 12,
"name": "Test"
},
{
"id": 2,
"name": "Beispiel"
},
{
"id": 3,
"name": "Sample"
}
] };
// We filter the array by id, the result is an array
// so we select the element 0
single_object = $filter('filter')(foo.results, function (d) {return d.id === 2;})[0];
// If you want to see the result, just check the log
console.log(single_object);
}]);

Simple DROP TYPE
first then CREATE TYPE
again with corrections/alterations?
There is a simple test to see if it is defined before you drop it ... much like a table, proc or function -- if I wasn't at work I would look what that is?
(I only skimmed above too ... if I read it wrong I apologise in advance! ;)
You can use Facebook Chat API to send private messages, here is an example in Ruby using xmpp4r_facebook
gem:
sender_chat_id = "-#{sender_uid}@chat.facebook.com"
receiver_chat_id = "-#{receiver_uid}@chat.facebook.com"
message_body = "message body"
message_subject = "message subject"
jabber_message = Jabber::Message.new(receiver_chat_id, message_body)
jabber_message.subject = message_subject
client = Jabber::Client.new(Jabber::JID.new(sender_chat_id))
client.connect
client.auth_sasl(Jabber::SASL::XFacebookPlatform.new(client,
ENV.fetch('FACEBOOK_APP_ID'), facebook_auth.token,
ENV.fetch('FACEBOOK_APP_SECRET')), nil)
client.send(jabber_message)
client.close
The ast.literal_eval
function comes close, but it will expect the string to be properly quoted first.
Of course Python's interpretation of backslash escapes depends on how the string is quoted (""
vs r""
vs u""
, triple quotes, etc) so you may want to wrap the user input in suitable quotes and pass to literal_eval
. Wrapping it in quotes will also prevent literal_eval
from returning a number, tuple, dictionary, etc.
Things still might get tricky if the user types unquoted quotes of the type you intend to wrap around the string.
When you want to check the condition at the beginning of the loop, simply negate the condition on a standard while
loop:
while(!cond) { ... }
If you need it at the end, use a do
... while
loop and negate the condition:
do { ... } while(!cond);
robocopy also tends to print empty lines even if it does not do anything. I'm filtering empty lines away using command like this:
robocopy /NDL /NJH /NJS /NP /NS /NC %fromDir% %toDir% %filenames% | findstr /r /v "^$"
You could use *ngIf="teamMembers != 0"
to check whether data is present
The following should work. Keep single connection open all time, and just create new commands and execute them.
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
using (SqlCommand command1 = new SqlCommand(commandText1, connection))
{
}
using (SqlCommand command2 = new SqlCommand(commandText2, connection))
{
}
// etc
}
I actually got exactly what you (and me) wanted, without the use of await, Promises, or inclusions of any (external) library (except our own).
Here's how to do it:
We're going to make a C++ module to go with node.js, and that C++ module function will make the HTTP request and return the data as a string, and you can use that directly by doing:
var myData = newModule.get(url);
ARE YOU READY to get started?
Step 1: make a new folder somewhere else on your computer, we're only using this folder to build the module.node file (compiled from C++), you can move it later.
In the new folder (I put mine in mynewFolder/src for organize-ness):
npm init
then
npm install node-gyp -g
now make 2 new files: 1, called something.cpp and for put this code in it (or modify it if you want):
#pragma comment(lib, "urlmon.lib")
#include <sstream>
#include <WTypes.h>
#include <node.h>
#include <urlmon.h>
#include <iostream>
using namespace std;
using namespace v8;
Local<Value> S(const char* inp, Isolate* is) {
return String::NewFromUtf8(
is,
inp,
NewStringType::kNormal
).ToLocalChecked();
}
Local<Value> N(double inp, Isolate* is) {
return Number::New(
is,
inp
);
}
const char* stdStr(Local<Value> str, Isolate* is) {
String::Utf8Value val(is, str);
return *val;
}
double num(Local<Value> inp) {
return inp.As<Number>()->Value();
}
Local<Value> str(Local<Value> inp) {
return inp.As<String>();
}
Local<Value> get(const char* url, Isolate* is) {
IStream* stream;
HRESULT res = URLOpenBlockingStream(0, url, &stream, 0, 0);
char buffer[100];
unsigned long bytesReadSoFar;
stringstream ss;
stream->Read(buffer, 100, &bytesReadSoFar);
while(bytesReadSoFar > 0U) {
ss.write(buffer, (long long) bytesReadSoFar);
stream->Read(buffer, 100, &bytesReadSoFar);
}
stream->Release();
const string tmp = ss.str();
const char* cstr = tmp.c_str();
return S(cstr, is);
}
void Hello(const FunctionCallbackInfo<Value>& arguments) {
cout << "Yo there!!" << endl;
Isolate* is = arguments.GetIsolate();
Local<Context> ctx = is->GetCurrentContext();
const char* url = stdStr(arguments[0], is);
Local<Value> pg = get(url,is);
Local<Object> obj = Object::New(is);
obj->Set(ctx,
S("result",is),
pg
);
arguments.GetReturnValue().Set(
obj
);
}
void Init(Local<Object> exports) {
NODE_SET_METHOD(exports, "get", Hello);
}
NODE_MODULE(cobypp, Init);
Now make a new file in the same directory called something.gyp
and put (something like) this in it:
{
"targets": [
{
"target_name": "cobypp",
"sources": [ "src/cobypp.cpp" ]
}
]
}
Now in the package.json file, add: "gypfile": true,
Now: in the console, node-gyp rebuild
If it goes through the whole command and says "ok" at the end with no errors, you're (almost) good to go, if not, then leave a comment..
But if it works then go to build/Release/cobypp.node (or whatever its called for you), copy it into your main node.js folder, then in node.js:
var myCPP = require("./cobypp")
var myData = myCPP.get("http://google.com").result;
console.log(myData);
..
response.end(myData);//or whatever
The missing part is:
thead, tbody {
display: block;
}
Doing sbt sbt-version
led to some error as
[error] Not a valid command: sbt-version (similar: writeSbtVersion, session)
[error] Not a valid project ID: sbt-version
[error] Expected ':'
[error] Not a valid key: sbt-version (similar: sbtVersion, version, sbtBinaryVersion)
[error] sbt-version
[error] ^
As you can see the hint similar: sbtVersion, version, sbtBinaryVersion
, all of them work but the correct one is generated by sbt sbtVersion
My observation is that even you have limit in the HQL (hibernate 3.x), it will be either causing parsing error or just ignored. (if you have order by + desc/asc before limit, it will be ignored, if you don't have desc/asc before limit, it will cause parsing error)
Something like this:
HTML:
<select id="choice">
<option value="0" selected="selected">Choose...</option>
<option value="1">Something</option>
<option value="2">Something else</option>
<option value="3">Another choice</option>
</select>
CSS:
#choice option { color: black; }
.empty { color: gray; }
JavaScript:
$("#choice").change(function () {
if($(this).val() == "0") $(this).addClass("empty");
else $(this).removeClass("empty")
});
$("#choice").change();
Working example: http://jsfiddle.net/Zmf6t/
In CSS:
textarea {
border-style: none;
border-color: Transparent;
overflow: auto;
}
You should check to make sure the value is not None before trying to perform any calculations on it:
my_value = None
if my_value is not None:
print int(my_value) / 2
Note: my_value
was intentionally set to None to prove the code works and that the check is being performed.
Add -confirm:$false to suppress confirmation.
As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub
. The simplest way is to change location
to str(location)
when using re.sub
. It wouldn't hurt to do it anyways even if it's already a str
.
letters_only = re.sub("[^a-zA-Z]", # Search for all non-letters
" ", # Replace all non-letters with spaces
str(location))
From Python documentation -> 8.3 Handling Exceptions:
A
try
statement may have more than one except clause, to specify handlers for different exceptions. At most one handler will be executed. Handlers only handle exceptions that occur in the corresponding try clause, not in other handlers of the same try statement. An except clause may name multiple exceptions as a parenthesized tuple, for example:except (RuntimeError, TypeError, NameError): pass
Note that the parentheses around this tuple are required, because except
ValueError, e:
was the syntax used for what is normally written asexcept ValueError as e:
in modern Python (described below). The old syntax is still supported for backwards compatibility. This meansexcept RuntimeError, TypeError
is not equivalent toexcept (RuntimeError, TypeError):
but toexcept RuntimeError as
TypeError:
which is not what you want.
To fix cross-origin-requests issues in a Node JS application:
npm i cors
And simply add the lines below to the app.js
let cors = require('cors')
app.use(cors())
You can use strtotime() to achieve this:
$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', $now)); // $now + 3 hours
You can add a little syntax sugar to the above solution with the following:
class Time
def to_ms
(self.to_f * 1000.0).to_i
end
end
start_time = Time.now
sleep(3)
end_time = Time.now
elapsed_time = end_time.to_ms - start_time.to_ms # => 3004
The best way I've found is:
<script type="text/javascript">
$(document).ready(function() {
$.fancybox(
$("#WRAPPER_FOR_hidden_div_with_content_to_show").html(), //fancybox works perfect with hidden divs
{
//fancybox options
}
);
});
</script>
Like @Lo Juego said, read the article
a, a:active, a:focus {
outline: none;
}
A rather nice way to handle this for missing COM classes:
Dim o:Set o = Nothing
On Error Resume Next
Set o = CreateObject("foo.bar")
On Error Goto 0
If o Is Nothing Then
Response.Write "Oups, foo.bar isn't installed on this server!"
Else
Response.Write "Foo bar found, yay."
End If
import java.util.Scanner;
class bigest {
public static void main (String[] args) {
Scanner input = new Scanner(System.in);
System.out.println ("how many number you want to put in the pot?");
int num = input.nextInt();
int numbers[] = new int[num];
for (int i = 0; i < num; i++) {
System.out.println ("number" + i + ":");
numbers[i] = input.nextInt();
}
for (int temp : numbers){
System.out.print (temp + "\t");
}
input.close();
}
}
Do not under any circumstances disable the constraints. This is an extremely stupid practice. You cannot maintain data integrity if you do things like this. Data integrity is the first consideration of a database because without it, you have nothing.
The correct method is to delete from the child tables before trying to delete the parent record. You are probably timing out because you have set up cascading deltes which is another bad practice in a large database.
The CSS class that can be changed to add a image to the JQuery slider handle is called ".ui-slider-horizontal .ui-slider-handle".
The following code shows a demo:
<!DOCTYPE html>
<html>
<head>
<link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
<script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script>
<style type="text/css">
.ui-slider-horizontal .ui-state-default {background: white url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat scroll 50% 50%;}
</style>
<script type="text/javascript">
$(document).ready(function(){
$("#slider").slider();
});
</script>
</head>
<body>
<div id="slider"></div>
</body>
</html>
I think registering a handle option was the old way of doing it and no longer supported in JQuery-ui 1.7.2?
This is a simple way to create a progressbar
import time,sys
toolbar_width = 50
# setting up toolbar [-------------------------------------]
sys.stdout.write("[%s]"%(("-")*toolbar_width))
sys.stdout.flush()
# each hash represents 2 % of the progress
for i in range(toolbar_width):
sys.stdout.write("\r") # return to start of line
sys.stdout.flush()
sys.stdout.write("[")#Overwrite over the existing text from the start
sys.stdout.write("#"*(i+1))# number of # denotes the progress completed
sys.stdout.flush()
time.sleep(0.1)
Use UNION
:
SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
UNION
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks
Or UNION ALL
if you want duplicates:
SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
UNION ALL
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks
Here is a script:
SH1.csv
to SH200.csv
import glob
import re
# Looking for filenames like 'SH1.csv' ... 'SH200.csv'
pattern = re.compile("^SH([1-9]|[1-9][0-9]|1[0-9][0-9]|200).csv$")
file_parts = [name for name in glob.glob('*.csv') if pattern.match(name)]
with open("file_merged.csv","wb") as file_merged:
for (i, name) in enumerate(file_parts):
with open(name, "rb") as file_part:
if i != 0:
next(file_part) # skip headers if not first file
file_merged.write(file_part.read())
Other people have suggested using in.nextLine()
to clear the buffer, which works for single-line input. As comments point out, however, sometimes System.in input can be multi-line.
You can instead create a new Scanner object where you want to clear the buffer if you are using System.in and not some other InputStream.
in = new Scanner(System.in);
If you do this, don't call in.close()
first. Doing so will close System.in, and so you will get NoSuchElementExceptions on subsequent calls to in.nextInt();
System.in probably shouldn't be closed during your program.
(The above approach is specific to System.in. It might not be appropriate for other input streams.)
If you really need to close your Scanner object before creating a new one, this StackOverflow answer suggests creating an InputStream wrapper for System.in that has its own close() method that doesn't close the wrapped System.in stream. This is overkill for simple programs, though.
I have tried this but nothing worked for me:

According to the official docs, browsers do not like it when you use the
Access-Control-Allow-Origin: "*"
header if you're also using the
Access-Control-Allow-Credentials: "true"
header. Instead, they want you to allow their origin specifically. If you still want to allow all origins, you can do some simple Apache magic to get it to work (make sure you have mod_headers
enabled):
Header set Access-Control-Allow-Origin "%{HTTP_ORIGIN}e" env=HTTP_ORIGIN
Browsers are required to send the Origin
header on all cross-domain requests. The docs specifically state that you need to echo this header back in the Access-Control-Allow-Origin
header if you are accepting/planning on accepting the request. That's what this Header
directive is doing.
Time::HiRes:
use Time::HiRes;
Time::HiRes::sleep(0.1); #.1 seconds
Time::HiRes::usleep(1); # 1 microsecond.
Ted's answer is amazing. I ended up using a smaller version of that in case anyone is interested. Useful when you are looking for one aggregation that depends on values from multiple columns:
df=pd.DataFrame({'a': [1,2,3,4,5,6], 'b': [1,1,0,1,1,0], 'c': ['x','x','y','y','z','z']})
a b c
0 1 1 x
1 2 1 x
2 3 0 y
3 4 1 y
4 5 1 z
5 6 0 z
df.groupby('c').apply(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())
c
x 2.0
y 4.0
z 5.0
I like this approach since I can still use aggregate. Perhaps people will let me know why apply is needed for getting at multiple columns when doing aggregations on groups.
It seems obvious now, but as long as you don't select the column of interest directly after the groupby, you will have access to all the columns of the dataframe from within your aggregation function.
df.groupby('c')['a'].aggregate(lambda x: x[x>1].mean())
df.groupby('c').aggregate(lambda x: x[(x['a']>1) & (x['b']==1)].mean())['a']
df.groupby('c').aggregate(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())
I hope this helps.
I agree with the first point, but times change. Corporations will respond, even if they're late adopters, if they see that there's an advantage to be had. Life is dynamic.
They were teaching Haskell and ML at Stanford in the late 90s. I'm sure that places like Carnegie Mellon, MIT, Stanford, and other good schools are presenting it to students.
I agree that most "expose relational databases on the web" apps will continue in that vein for a long time. Java EE, .NET, RoR, and PHP have evolved some pretty good solutions to that problem.
You've hit on something important: It might be the problem that can't be solved easily by other means that will boost functional programming. What would that be?
Will massive multicore hardware and cloud computing push them along?
If you did literally this:
encodeURIComponent('&')
Then the result is %26
, you can test it here. Make sure the string you are encoding is just &
and not &
to begin with...otherwise it is encoding correctly, which is likely the case. If you need a different result for some reason, you can do a .replace(/&/g,'&')
before the encoding.
Old question; but I always try to use fastest code!
I had a huge list with 69 millions of uint64. np.array() was fastest for me.
df['hashes'] = hashes
Time spent: 17.034842014312744
df['hashes'] = pd.Series(hashes).values
Time spent: 17.141014337539673
df['key'] = np.array(hashes)
Time spent: 10.724546194076538
A little bit off topic maybe, but for modern browsers (IE9 and newer) you can use the css odd/even selectors to achieve want you want.
tr:nth-child(even) { /* your alt-row stuff */}
tr:nth-child(odd) { /* the other rows */ }
or
tr { /* all table rows */ }
tr:nth-child(even) { /* your alt-row stuff */}
Speaking of GraphHopper, a fast Open Source route planner based on OpenStreetMap, I have read a bit literature and implemented some methods. The simplest solution is a Dijkstra and a simple improvement is a bidirectional Dijkstra which explores roughly only the half of the nodes. With bidirctional Dijkstra a route through entire Germany takes already 1sec (for car mode), in C it would be probably only 0.5s or so ;)
I've created an animated gif of a real path search with bidirectional Dijkstra here. Also there are some more ideas to make Dijkstra faster like doing A*, which is a "goal-oriented Dijkstra". Also I've create a gif-animation for it.
But how to do it (a lot) faster?
The problem is that for a path search all nodes between the locations have to be explored and this is really costly as already in Germany there are several millions of them. But an additional pain point of Dijkstra etc is that such searches uses lots of RAM.
There are heuristic solutions but also exact solutions which organzize the graph (road network) in hierarchical layers, both have pro&cons and mainly solve the speed and RAM problem. I've listed some of them in this answer.
For GraphHopper I decided to use Contraction Hierarchies because it is relative 'easy' to implement and does not take ages for preparation of the graph. It still results in very fast response times like you can test at our online instance GraphHopper Maps. E.g. from south Africa to east China which results in a 23000km distance and nearly 14 days driving time for car and took only ~0.1s on the server.
You could always include it using __DIR__
:
include(dirname(__DIR__).'/config.php');
__DIR__
is a 'magical constant' and returns the directory of the current file without the trailing slash. It's actually an absolute path, you just have to concatenate the file name to __DIR__
. In this case, as we need to ascend a directory we use PHP's dirname
which ascends the file tree, and from here we can access config.php
.
You could set the root path in this method too:
define('ROOT_PATH', dirname(__DIR__) . '/');
in test.php would set your root to be at the /root/
level.
include(ROOT_PATH.'config.php');
Should then work to include the config file from where you want.
I was getting this error attempting to run "php artisan migrate" on Windows with a virtual box / vagrant / homestead installation.
The documentation said I had to run this command on the virtual machine.
This worked!!!
make sure to do it inside your current project folder.
This is the notorious floating point rounding issue. Just add a very small number, to correct the issue.
double a;
a=3669.0;
int b;
b=a+ 1e-9;
Additional note to the people thinking that an automatic one-time-only inclusion of header files is always desired: I build code generators using double or multiple inclusion of header files since decades. Especially for generation of protocol library stubs I find it very comfortable to have a extremely portable and powerful code generator with no additional tools and languages. I'm not the only developer using this scheme as this blogs X-Macros show. This wouldn't be possible to do without the missing automatic guarding.
First we can build a BST from unsorted array which takes O(n) time and from the BST we can find the kth smallest element in O(log(n)) which over all counts to an order of O(n).
If you still need an answer then in my case it works after (re)download Android image but directly from Android Studio not through Visual Studio button.
I'm using HybridAuth and was running into this error connecting to Twitter. I tracked it down to (me) sending Twitter an incorrectly cased request type (get/post instead of GET/POST).
This would cause a 215:
$call = '/search/tweets.json';
$call_type = 'get';
$call_args = array(
'q' => 'pancakes',
'count' => 5,
);
$response = $provider_api->api( $call, $call_type, $call_args );
This would not:
$call = '/search/tweets.json';
$call_type = 'GET';
$call_args = array(
'q' => 'pancakes',
'count' => 5,
);
$response = $provider_api->api( $call, $call_type, $call_args );
Side note: In the case of HybridAuth the following also would not (because HA internally provides the correctly-cased value for the request type):
$call = '/search/tweets.json';
$call_args = array(
'q' => 'pancakes',
'count' => 5,
);
$response = $providers['Twitter']->get( $call, $call_args );
A Spring Boot with Thymeleaf solution could look like:
Lets say my context-path is /app/
In Thymeleaf you can get it via:
<script th:inline="javascript">
/*<![CDATA[*/
let contextPath = /*[[@{/}]]*/
/*]]>*/
</script>
Update: Google Forms can now upload files. This answer was posted before Google Forms had the capability to upload files.
This solution does not use Google Forms. This is an example of using an Apps Script Web App, which is very different than a Google Form. A Web App is basically a website, but you can't get a domain name for it. This is not a modification of a Google Form, which can't be done to upload a file.
NOTE: I did have an example of both the UI Service and HTML Service, but have removed the UI Service example, because the UI Service is deprecated.
NOTE: The only sandbox setting available is now IFRAME
. I you want to use an onsubmit
attribute in the beginning form tag: <form onsubmit="myFunctionName()">
, it may cause the form to disappear from the screen after the form submission.
If you were using NATIVE mode, your file upload Web App may no longer be working. With NATIVE mode, a form submission would not invoke the default behavior of the page disappearing from the screen. If you were using NATIVE mode, and your file upload form is no longer working, then you may be using a "submit" type button. I'm guessing that you may also be using the "google.script.run" client side API to send data to the server. If you want the page to disappear from the screen after a form submission, you could do that another way. But you may not care, or even prefer to have the page stay on the screen. Depending upon what you want, you'll need to configure the settings and code a certain way.
If you are using a "submit" type button, and want to continue to use it, you can try adding event.preventDefault();
to your code in the submit event handler function. Or you'll need to use the google.script.run
client side API.
A custom form for uploading files from a users computer drive, to your Google Drive can be created with the Apps Script HTML Service. This example requires writing a program, but I've provide all the basic code here.
This example shows an upload form with Google Apps Script HTML Service.
There are various ways to end up at the Google Apps Script code editor.
I mention this because if you are not aware of all the possibilities, it could be a little confusing. Google Apps Script can be embedded in a Google Site, Sheets, Docs or Forms, or used as a stand alone app.
This example is a "Stand Alone" app with HTML Service.
HTML Service - Create a web app using HTML, CSS and Javascript
Google Apps Script only has two types of files inside of a Project
:
Script files have a .gs
extension. The .gs
code is a server side code written in JavaScript, and a combination of Google's own API.
Copy and Paste the following code
Save It
Create the first Named Version
Publish it
Set the Permissions
and you can start using it.
Code.gs file (Created by Default)
//For this to work, you need a folder in your Google drive named:
// 'For Web Hosting'
// or change the hard coded folder name to the name of the folder
// you want the file written to
function doGet(e) {

Create an html file:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<h1 id="main-heading">Main Heading</h1>
<br/>
<div id="formDiv">
<form id="myForm">
<input name="picToLoad" type="file" /><br/>
<input type="button" value="Submit" onclick="picUploadJs(this.parentNode)" />
</form>
</div>
<div id="status" style="display: none">
<!-- div will be filled with innerHTML after form submission. -->
Uploading. Please wait...
</div>
</body>
<script>
function picUploadJs(frmData) {
document.getElementById('status').style.display = 'inline';
google.script.run
.withSuccessHandler(updateOutput)
.processForm(frmData)
};
// Javascript function called by "submit" button handler,
// to show results.
function updateOutput() {
var outputDiv = document.getElementById('status');
outputDiv.innerHTML = "The File was UPLOADED!";
}
</script>
</html>
This is a full working example. It only has two buttons and one <div>
element, so you won't see much on the screen. If the .gs
script is successful, true is returned, and an onSuccess
function runs. The onSuccess function (updateOutput) injects inner HTML into the div
element with the message, "The File was UPLOADED!"
File
, Manage Version
then Save the first VersionPublish
, Deploy As Web App
then UpdateWhen you run the Script the first time, it will ask for permissions because it's saving files to your drive. After you grant permissions that first time, the Apps Script stops, and won't complete running. So, you need to run it again. The script won't ask for permissions again after the first time.
The Apps Script file will show up in your Google Drive. In Google Drive you can set permissions for who can access and use the script. The script is run by simply providing the link to the user. Use the link just as you would load a web page.
Another example of using the HTML Service can be seen at this link here on StackOverflow:
NOTES about deprecated UI Service:
There is a difference between the UI Service, and the Ui getUi()
method of the Spreadsheet Class (Or other class) The Apps Script UI Service was deprecated on Dec. 11, 2014. It will continue to work for some period of time, but you are encouraged to use the HTML Service.
Google Documentation - UI Service
Even though the UI Service is deprecated, there is a getUi()
method of the spreadsheet class to add custom menus, which is NOT deprecated:
Spreadsheet Class - Get UI method
I mention this because it could be confusing because they both use the terminology UI.
The UI method returns a Ui
return type.
You can add HTML to a UI Service, but you can't use a <button>
, <input>
or <script>
tag in the HTML with the UI Service.
Here is a link to a shared Apps Script Web App file with an input form:
Inline methods are simply a compiler optimization where the code of a function is rolled into the caller.
There's no mechanism by which to do this in C#, and they're to be used sparingly in languages where they are supported -- if you don't know why they should be used somewhere, they shouldn't be.
Edit: To clarify, there are two major reasons they need to be used sparingly:
It's best to leave things alone and let the compiler do its work, then profile and figure out if inline is the best solution for you. Of course, some things just make sense to be inlined (mathematical operators particularly), but letting the compiler handle it is typically the best practice.
This is an example to read and write binary jjpg or wmv video file. FILE *fout; FILE *fin;
Int ch;
char *s;
fin=fopen("D:\\pic.jpg","rb");
if(fin==NULL)
{ printf("\n Unable to open the file ");
exit(1);
}
fout=fopen("D:\\ newpic.jpg","wb");
ch=fgetc(fin);
while (ch!=EOF)
{
s=(char *)ch;
printf("%c",s);
ch=fgetc (fin):
fputc(s,fout);
s++;
}
printf("data read and copied");
fclose(fin);
fclose(fout);
First you need to get the counts for each category, i.e. how many Bads and Goods and so on are there for each group (Food, Music, People). This would be done like so:
raw <- read.csv("http://pastebin.com/raw.php?i=L8cEKcxS",sep=",")
raw[,2]<-factor(raw[,2],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,3]<-factor(raw[,3],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,4]<-factor(raw[,4],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw=raw[,c(2,3,4)] # getting rid of the "people" variable as I see no use for it
freq=table(col(raw), as.matrix(raw)) # get the counts of each factor level
Then you need to create a data frame out of it, melt it and plot it:
Names=c("Food","Music","People") # create list of names
data=data.frame(cbind(freq),Names) # combine them into a data frame
data=data[,c(5,3,1,2,4)] # sort columns
# melt the data frame for plotting
data.m <- melt(data, id.vars='Names')
# plot everything
ggplot(data.m, aes(Names, value)) +
geom_bar(aes(fill = variable), position = "dodge", stat="identity")
Is this what you're after?
To clarify a little bit, in ggplot multiple grouping bar you had a data frame that looked like this:
> head(df)
ID Type Annee X1PCE X2PCE X3PCE X4PCE X5PCE X6PCE
1 1 A 1980 450 338 154 36 13 9
2 2 A 2000 288 407 212 54 16 23
3 3 A 2020 196 434 246 68 19 36
4 4 B 1980 111 326 441 90 21 11
5 5 B 2000 63 298 443 133 42 21
6 6 B 2020 36 257 462 162 55 30
Since you have numerical values in columns 4-9, which would later be plotted on the y axis, this can be easily transformed with reshape
and plotted.
For our current data set, we needed something similar, so we used freq=table(col(raw), as.matrix(raw))
to get this:
> data
Names Very.Bad Bad Good Very.Good
1 Food 7 6 5 2
2 Music 5 5 7 3
3 People 6 3 7 4
Just imagine you have Very.Bad
, Bad
, Good
and so on instead of X1PCE
, X2PCE
, X3PCE
. See the similarity? But we needed to create such structure first. Hence the freq=table(col(raw), as.matrix(raw))
.
This problem also arise when we don't give the single or double quotes to the database value.
Wrong way:
$query ="INSERT INTO tabel_name VALUE ($value1,$value2)";
As database inserting values must be in quotes ' '/" "
Right way:
$query ="INSERT INTO STUDENT VALUE ('$roll_no','$name','$class')";
With Spring it's easy. Be it a file, or folder, or even multiple files, there are chances, you can do it via injection.
This example demonstrates the injection of multiple files located in x/y/z
folder.
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.Resource;
import org.springframework.stereotype.Service;
@Service
public class StackoverflowService {
@Value("classpath:x/y/z/*")
private Resource[] resources;
public List<String> getResourceNames() {
return Arrays.stream(resources)
.map(Resource::getFilename)
.collect(Collectors.toList());
}
}
It does work for resources in the filesystem as well as in JARs.

Follow these basic steps to fix this problem,
Step 1: Go to Dashboard,
Step 2: Go to "App Review" tab,
Step 3: Enable the "Make test public?" option, Like Below image,
Just to complete it:
(gdb) p (char[10]) *($ebx)
$87 = "asdfasdfe\n"
You must give a length, but may change the representation of that string:
(gdb) p/x (char[10]) *($ebx)
$90 = {0x61,
0x73,
0x64,
0x66,
0x61,
0x73,
0x64,
0x66,
0x65,
0xa}
This may be useful if you want to debug by their values
Wrote the below function that allows me to quickly check to see if an index exists; works just like OBJECT_ID.
CREATE FUNCTION INDEX_OBJECT_ID (
@tableName VARCHAR(128),
@indexName VARCHAR(128)
)
RETURNS INT
AS
BEGIN
DECLARE @objectId INT
SELECT @objectId = i.object_id
FROM sys.indexes i
WHERE i.object_id = OBJECT_ID(@tableName)
AND i.name = @indexName
RETURN @objectId
END
GO
EDIT: This just returns the OBJECT_ID of the table, but it will be NULL if the index doesn't exist. I suppose you could set this to return index_id, but that isn't super useful.
You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/.
Your resource methods won't get hit, so their headers will never get set. The reason is that there is what's called a preflight request before the actual request, which is an OPTIONS request. So the error comes from the fact that the preflight request doesn't produce the necessary headers. check that you will need to add following in your .htaccess file:
Header set Access-Control-Allow-Origin "*"
Judging by your other post: How to Get the inner text of a span in PHP. You're quite new to web programming, and need to learn about the differences between code on the client (JavaScript) and code on the server (PHP).
As for the correct approach to grabbing the span text from the client I recommend Johns answer.
These are a good place to get started.
JavaScript: https://stackoverflow.com/questions/11246/best-resources-to-learn-javascript
PHP: https://stackoverflow.com/questions/772349/what-is-a-good-online-tutorial-for-php
Also I recommend using jQuery (Once you've got some JavaScript practice) it will eliminate most of the cross-browser compatability issues that you're going to have. But don't use it as a crutch to learn on, it's good to understand JavaScript too. http://jquery.com/

Below code will look for last used row in sheet1 and copy the entire range from A1 upto last used row in column A to Sheet2 at exact same location.
Sub test()
Dim lastRow As Long
lastRow = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row
Sheets("Sheet2").Range("A1:A" & lastRow).Value = Sheets("Sheet1").Range("A1:A" & lastRow).Value
End Sub
numpy.linspace()
gives you a one-dimensional NumPy array. For example:
>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([ 1., 2., 3., 4., 5., 6., 7., 8., 9., 10.])
Therefore:
for index,point in my_array
cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:
>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])
Now you can do this:
>>> for x, y in two_d:
print(x, y)
1 2
4 5
The '\r'
character is the carriage return, and the carriage return-newline pair is both needed for newline in a network virtual terminal session.
From the old telnet specification (RFC 854) (page 11):
The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").
However, from the latest specification (RFC5198) (page 13):
...
In Net-ASCII, CR MUST NOT appear except when immediately followed by either NUL or LF, with the latter (CR LF) designating the "new line" function. Today and as specified above, CR should generally appear only when followed by LF. Because page layout is better done in other ways, because NUL has a special interpretation in some programming languages, and to avoid other types of confusion, CR NUL should preferably be avoided as specified above.
LF CR SHOULD NOT appear except as a side-effect of multiple CR LF sequences (e.g., CR LF CR LF).
So newline in Telnet should always be '\r\n'
but most implementations have either not been updated, or keeps the old '\n\r'
for backwards compatibility.
To disable console.log
only:
console.log = function() {};
To disable all functions that write to the console:
for (let func in console) {
console[func] = function() {};
}
You can mix C++ with Objective-C if you do it carefully. There are a few caveats but generally speaking they can be mixed. If you want to keep them separate, you can set up a standard C wrapper function that gives the Objective-C object a usable C-style interface from non-Objective-C code (pick better names for your files, I have picked these names for verbosity):
#ifndef __MYOBJECT_C_INTERFACE_H__
#define __MYOBJECT_C_INTERFACE_H__
// This is the C "trampoline" function that will be used
// to invoke a specific Objective-C method FROM C++
int MyObjectDoSomethingWith (void *myObjectInstance, void *parameter);
#endif
#import "MyObject-C-Interface.h"
// An Objective-C class that needs to be accessed from C++
@interface MyObject : NSObject
{
int someVar;
}
// The Objective-C member function you want to call from C++
- (int) doSomethingWith:(void *) aParameter;
@end
#import "MyObject.h"
@implementation MyObject
// C "trampoline" function to invoke Objective-C method
int MyObjectDoSomethingWith (void *self, void *aParameter)
{
// Call the Objective-C method using Objective-C syntax
return [(id) self doSomethingWith:aParameter];
}
- (int) doSomethingWith:(void *) aParameter
{
// The Objective-C function you wanted to call from C++.
// do work here..
return 21 ; // half of 42
}
@end
#include "MyCPPClass.h"
#include "MyObject-C-Interface.h"
int MyCPPClass::someMethod (void *objectiveCObject, void *aParameter)
{
// To invoke an Objective-C method from C++, use
// the C trampoline function
return MyObjectDoSomethingWith (objectiveCObject, aParameter);
}
The wrapper function does not need to be in the same .m
file as the Objective-C class, but the file that it does exist in needs to be compiled as Objective-C code. The header that declares the wrapper function needs to be included in both CPP and Objective-C code.
(NOTE: if the Objective-C implementation file is given the extension ".m" it will not link under Xcode. The ".mm" extension tells Xcode to expect a combination of Objective-C and C++, i.e., Objective-C++.)
You can implement the above in an Object-Orientented manner by using the PIMPL idiom. The implementation is only slightly different. In short, you place the wrapper functions (declared in "MyObject-C-Interface.h") inside a class with a (private) void pointer to an instance of MyClass.
#ifndef __MYOBJECT_C_INTERFACE_H__
#define __MYOBJECT_C_INTERFACE_H__
class MyClassImpl
{
public:
MyClassImpl ( void );
~MyClassImpl( void );
void init( void );
int doSomethingWith( void * aParameter );
void logMyMessage( char * aCStr );
private:
void * self;
};
#endif
Notice the wrapper methods no longer require the void pointer to an instance of MyClass; it is now a private member of MyClassImpl. The init method is used to instantiate a MyClass instance;
#import "MyObject-C-Interface.h"
@interface MyObject : NSObject
{
int someVar;
}
- (int) doSomethingWith:(void *) aParameter;
- (void) logMyMessage:(char *) aCStr;
@end
#import "MyObject.h"
@implementation MyObject
MyClassImpl::MyClassImpl( void )
: self( NULL )
{ }
MyClassImpl::~MyClassImpl( void )
{
[(id)self dealloc];
}
void MyClassImpl::init( void )
{
self = [[MyObject alloc] init];
}
int MyClassImpl::doSomethingWith( void *aParameter )
{
return [(id)self doSomethingWith:aParameter];
}
void MyClassImpl::logMyMessage( char *aCStr )
{
[(id)self doLogMessage:aCStr];
}
- (int) doSomethingWith:(void *) aParameter
{
int result;
// ... some code to calculate the result
return result;
}
- (void) logMyMessage:(char *) aCStr
{
NSLog( aCStr );
}
@end
Notice that MyClass is instantiated with a call to MyClassImpl::init. You could instantiate MyClass in MyClassImpl's constructor, but that generally isn't a good idea. The MyClass instance is destructed from MyClassImpl's destructor. As with the C-style implementation, the wrapper methods simply defer to the respective methods of MyClass.
#ifndef __MYCPP_CLASS_H__
#define __MYCPP_CLASS_H__
class MyClassImpl;
class MyCPPClass
{
enum { cANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING = 42 };
public:
MyCPPClass ( void );
~MyCPPClass( void );
void init( void );
void doSomethingWithMyClass( void );
private:
MyClassImpl * _impl;
int _myValue;
};
#endif
#include "MyCPPClass.h"
#include "MyObject-C-Interface.h"
MyCPPClass::MyCPPClass( void )
: _impl ( NULL )
{ }
void MyCPPClass::init( void )
{
_impl = new MyClassImpl();
}
MyCPPClass::~MyCPPClass( void )
{
if ( _impl ) { delete _impl; _impl = NULL; }
}
void MyCPPClass::doSomethingWithMyClass( void )
{
int result = _impl->doSomethingWith( _myValue );
if ( result == cANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING )
{
_impl->logMyMessage( "Hello, Arthur!" );
}
else
{
_impl->logMyMessage( "Don't worry." );
}
}
You now access calls to MyClass through a private implementation of MyClassImpl. This approach can be advantageous if you were developing a portable application; you could simply swap out the implementation of MyClass with one specific to the other platform ... but honestly, whether this is a better implementation is more a matter of taste and needs.
An alternative is:
System.out.println(opt.map(o -> "Found")
.orElse("Not found"));
I don't think it improves readability though.
Or as Marko suggested, use a ternary operator:
System.out.println(opt.isPresent() ? "Found" : "Not found");
This is a slight modification from a previous solution. My example looks for stderr redirection in bash scripts:
grep '2>' $(find . -name "*.bash")
require 'date'
current_time = DateTime.now
current_time.strftime "%d/%m/%Y %H:%M"
# => "14/09/2011 17:02"
current_time.next_month.strftime "%d/%m/%Y %H:%M"
# => "14/10/2011 17:02"
Thanks, Varun Rathore
. It works perfectly!

In general it's a pain to write a regular expression not containing a particular string. We had to do this for models of computation - you take an NFA, which is easy enough to define, and then reduce it to a regular expression. The expression for things not containing "cat" was about 80 characters long.
Edit: I just finished and yes, it's:
aa([^a] | a[^a])aa
Here is a very brief tutorial. I found some great ones before, but I can't see them anymore.
For the sake of completeness: the previous answers tell how to set the upstream branch, but not how to see it.
There are a few ways to do this:
git branch -vv
shows that info for all branches. (formatted in blue in most terminals)
cat .git/config
shows this also.
For reference:
<input type="text" name="myinput" id="myinput" onkeypress="return isNumber(event);" />
and in the js:
function isNumber(e){
e = e || window.event;
var charCode = e.which ? e.which : e.keyCode;
return /\d/.test(String.fromCharCode(charCode));
}
or you can write it in a complicated bu useful way:
<input onkeypress="return /\d/.test(String.fromCharCode(((event||window.event).which||(event||window.event).which)));" type="text" name="myinput" id="myinput" />
Note:cross-browser and regex in literal.

From the docs:
_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.
So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.
Edit: Further reading led me here:
http://www.analyticsmarket.com/blog/edit-ecommerce-data
Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.
This question has been answered properly, but I would like to add my approach, it's not that different than what the others have mentioned.
I use different layouts pages to call different headers/footers, some call this layout, some call it template etc.
Edit core/Loader.php
and add your own function to load your layout, I called the function e.g.layout
.
Create your own template page and make it call header/footer
for you, I called it default.php
and put in a new directory e.g. view/layout/default.php
Call your own view page from your controller as you would normally. But instead of calling $this-load->view
use $this->load->layout
, layout function will call the default.php
and default.php
will call your header and footer.
1)
In core/Loader.php
under view() function I duplicated it and added mine
public function layout($view, $vars = array(), $return = FALSE)
{
$vars["display_page"] = $view;//will be called from the layout page
$layout = isset($vars["layout"]) ? $vars["layout"] : "default";
return $this->_ci_load(array('_ci_view' => "layouts/$layout", '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));
}
2) Create layout folder and put default.php in it in view/layout/default.php
$this->load->view('parts/header');//or wherever your header is
$this->load->view($display_page);
$this->load->view('parts/footer');or wherever your footer is
3) From your controller, call your layout
$this->load->layout('projects');// will use 'view/layout/default.php' layout which in return will call header and footer as well.
To use another layout, include the new layout name in your $data
array
$data["layout"] = "full_width";
$this->load->layout('projects', $data);// will use full_width.php layout
and of course you must have your new layout in the layout directory as in:
view/layout/full_width.php
Methods can only declare local variables. That is why the compiler reports an error when you try to declare it as public.
In the case of local variables you can not use any kind of accessor (public, protected or private).
You should also know what the static keyword means. In method checkYourself
, you use the Integer array locations
.
The static keyword distinct the elements that are accessible with object creation. Therefore they are not part of the object itself.
public class Test { //Capitalized name for classes are used in Java
private final init[] locations; //key final mean that, is must be assigned before object is constructed and can not be changed later.
public Test(int[] locations) {

Since it appears you are using jQuery, here is a jQuery solution.
$(function() {
$('#Eframe').on("mousewheel", function() {
alert($(document).scrollTop());
});
});
Not much to explain here. If you want, here is the jQuery documentation.
please try to install the dependencie with pip, run this command:
sudo pip install -U setuptools
Someone linked me this: What is the best way to move an element that's on the top to the bottom in Responsive design.
The solution in that worked perfectly. Though it doesn’t support old IE, that doesn’t matter for me, since I’m using responsive design for mobile. And it works for most mobile browsers.
Basically, I had this:
@media (max-width: 30em) {
.container {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-box-orient: vertical;
-moz-box-orient: vertical;
-webkit-flex-direction: column;
-ms-flex-direction: column;
flex-direction: column;
/* optional */
-webkit-box-align: start;
-moz-box-align: start;
-ms-flex-align: start;
-webkit-align-items: flex-start;
align-items: flex-start;
}
.container .first_div {
-webkit-box-ordinal-group: 2;
-moz-box-ordinal-group: 2;
-ms-flex-order: 2;
-webkit-order: 2;
order: 2;
}
.container .second_div {
-webkit-box-ordinal-group: 1;
-moz-box-ordinal-group: 1;
-ms-flex-order: 1;
-webkit-order: 1;
order: 1;
}
}
This worked better than floats for me, because I needed them stacked on top of each other and I had about five different divs that I had to swap around the position of.
I think every process you make start executing the line you create so something like this...
pid=fork() at line 6. fork function returns 2 values
you have 2 pids, first pid=0 for child and pid>0 for parent
so you can use if to separate
.
/*
sleep(int time) to see clearly
<0 fail
=0 child
>0 parent
*/
int main(int argc, char** argv) {
pid_t childpid1, childpid2;
printf("pid = process identification\n");
printf("ppid = parent process identification\n");
childpid1 = fork();
if (childpid1 == -1) {
printf("Fork error !\n");
}
if (childpid1 == 0) {
sleep(1);
printf("child[1] --> pid = %d and ppid = %d\n",
getpid(), getppid());
} else {
childpid2 = fork();
if (childpid2 == 0) {
sleep(2);
printf("child[2] --> pid = %d and ppid = %d\n",
getpid(), getppid());
} else {
sleep(3);
printf("parent --> pid = %d\n", getpid());
}
}
return 0;
}
//pid = process identification
//ppid = parent process identification
//child[1] --> pid = 2399 and ppid = 2398
//child[2] --> pid = 2400 and ppid = 2398
//parent --> pid = 2398
you did not use S anywhere in your algorithm (besides modifying it). the idea of dijkstra is once a vertex is on S, it will not be modified ever again. in this case, once B is inside S, you will not reach it again via C.
this fact ensures the complexity of O(E+VlogV) [otherwise, you will repeat edges more then once, and vertices more then once]
in other words, the algorithm you posted, might not be in O(E+VlogV), as promised by dijkstra's algorithm.
well i found out the mistake i was committing i was adding a group to the project instead of adding real directory for more instructions
Not sure if you have resolved it (and if I understand correctly), but here's my idea:
If parent receives myProp, and you want it to pass to child and watch it in child, then parent has to have copy of myProp (not reference).
Try this:
new Vue({
el: '#app',
data: {
text: 'Hello'
},
components: {
'parent': {
props: ['myProp'],
computed: {
myInnerProp() { return myProp.clone(); } //eg. myProp.slice() for array
}
},
'child': {
props: ['myProp'],
watch: {
myProp(val, oldval) { now val will differ from oldval }
}
}
}
}
and in html:
<child :my-prop="myInnerProp"></child>
actually you have to be very careful when working on complex collections in such situations (passing down few times)
$total = count($_FILES['txt_gallery']['name']);
$filename_arr = [];
$filename_arr1 = [];
for( $i=0 ; $i < $total ; $i++ ) {
$tmpFilePath = $_FILES['txt_gallery']['tmp_name'][$i];
if ($tmpFilePath != ""){
$newFilePath = "../uploaded/" .date('Ymdhis').$i.$_FILES['txt_gallery']['name'][$i];
$newFilePath1 = date('Ymdhis').$i.$_FILES['txt_gallery']['name'][$i];
if(move_uploaded_file($tmpFilePath, $newFilePath)) {
$filename_arr[] = $newFilePath;
$filename_arr1[] = $newFilePath1;
}
}
}
$file_names = implode(',', $filename_arr1);
var_dump($file_names); exit;
Here’s a simple and straightforward answer to your question, (I think). I am using the TSQL2012 sample database and I am returning only even or odd rows based on “employeeID” in the “HR.Employees” table.
USE TSQL2012;
GO
Return only Even numbers of the employeeID:
SELECT *
FROM HR.Employees
WHERE (empid % 2) = 0;
GO
Return only Odd numbers of the employeeID:
SELECT *
FROM HR.Employees
WHERE (empid % 2) = 1;
GO
Hopefully, that’s the answer you were looking for.
After reading cURL documentation on the options you used, it looks like the private key of certificate is not in the same file. If it is in different file, you need to mention it using --key file and supply passphrase.
So, please make sure that either cert.pem has private key (along with the certificate) or supply it using --key option.
Also, this documentation mentions that Note that this option assumes a "certificate" file that is the private key and the private certificate concatenated!
How they are concatenated? It is quite easy. Put them one after another in the same file.
You can get more help on this here.
I believe this might help you.

This will help you in getting the first or default value in your Linq List search
var results = _List.Where(item => item == search).FirstOrDefault();
This search will find the first or default value it will return.
You can use a Deferred objects for ASYNC loading.
function load_img_async(source) {
return $.Deferred (function (task) {
var image = new Image();
image.onload = function () {task.resolve(image);}
image.onerror = function () {task.reject();}
image.src=source;
}).promise();
}
$.when(load_img_async(IMAGE_URL)).done(function (image) {
$(#id).empty().append(image);
});
Please pay attention: image.onload must be before image.src to prevent problems with cache.
You may need to disable the hypervisor.
So, follow the next steps:
1) Open command prompt as Administrator
2) Run bcdedit to check hypervisor status:
bcdedit
3) Check hypervisor launch type:
4) If is set to auto then disable it:
bcdedit /set hypervisorlaunchtype off
5) Reboot host machine and launch VirtualBox again
Just for super noobs like me wondering how or what people meant by
PRAGMA table_info('table_name')
You want to use use that as your prepare statement as shown below. Doing so selects a table that looks like this except is populated with values pertaining to your table.
cid name type notnull dflt_value pk
---------- ---------- ---------- ---------- ---------- ----------
0 id integer 99 1
1 name 0 0
Where id and name are the actual names of your columns. So to get that value you need to select column name by using:
//returns the name
sqlite3_column_text(stmt, 1);
//returns the type
sqlite3_column_text(stmt, 2);
Which will return the current row's column's name. To grab them all or find the one you want you need to iterate through all the rows. Simplest way to do so would be in the manner below.
//where rc is an int variable if wondering :/
rc = sqlite3_prepare_v2(dbPointer, "pragma table_info ('your table name goes here')", -1, &stmt, NULL);
if (rc==SQLITE_OK)
{
//will continue to go down the rows (columns in your table) till there are no more
while(sqlite3_step(stmt) == SQLITE_ROW)
{
sprintf(colName, "%s", sqlite3_column_text(stmt, 1));
//do something with colName because it contains the column's name
}
}
// It happens when you are not setting the adapter during the creation phase: call notifyDataSetChanged() when api response is getting Its Working
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
magazineAdapter = new MagazineAdapter(getContext(), null, this );
newClipRecyclerView.setAdapter(magazineAdapter);
magazineAdapter.notifyDataSetChanged();
APICall();
}
public void APICall() {
if(Response.isSuccessfull()){
mRecyclerView.setAdapter(mAdapter);
}
}
Just move setting the adapter into onCreate with an empty data and when you have the data call:
mAdapter.notifyDataSetChanged();
For entity Framework Core 2.0 or above, the correct way to do this is:
var firstName = "John";
var id = 12;
ctx.Database.ExecuteSqlCommand($"Update [User] SET FirstName = {firstName} WHERE Id = {id}";
Note that Entity Framework will produce the two parameters for you, so you are protected from Sql Injection.
Also note that it is NOT:
var firstName = "John";
var id = 12;
var sql = $"Update [User] SET FirstName = {firstName} WHERE Id = {id}";
ctx.Database.ExecuteSqlCommand(sql);
because this does NOT protect you from Sql Injection, and no parameters are produced.
See this for more.
A .java file is called a compilation unit. Each compilation unit may contain any number of top-level classes and interfaces. If there are no public top-level types then the compilation unit can be named anything.
//Multiple.java
//preceding package and import statements
class MyClass{...}
interface Service{...}
...
//No public classes or interfaces
...
There can be only one public class/interface in a compilation unit. The c.u. must be named exactly as this public top-level type.
//Test.java
//named exactly as the public class Test
public class Test{...}
//!public class Operations{...}
interface Selector{...}
...
//Other non-public classes/interfaces

My version:
while '' in all_lines:
all_lines.pop(all_lines.index(''))

ArrayList<Integer> list = new ArrayList<Integer>();
list.forEach((n) -> System.out.println(n));
Ok, no one has answered this yet but I managed to figure it out and get it working after also posting on the spyder discussion boards. For any libraries that you want to add that aren't included in the default search path of spyder, you need to go into Tools and add a path to each library via the PYTHONPATH manager. You'll then need to update the module names list from the same menu and restart spyder before the changes take effect.
The XmlTextWriter is usually used for generating (not updating) XML content. When you load the xml file into an XmlDocument, you don't need a separate writer.
Just update the node you have selected and .Save() that XmlDocument.
Make sure you've set your target API (different from the target SDK) in the Project Properties (not the manifest) to be at least 4.0/API 14.
In case someone is using C# (or see Note about VB.NET below) and has reached this point, but is still stuck, please read on.
Joshua's answer helped me, but not all the way. You will notice Peter asked "Where would you get the button from?", but was unanswered.
The only way it worked for me was to do one of the following to add my event hander (after setting my DataGridView's DataSource to my DataTable and after adding the DataGridViewButtonColumn to the DataGridView):
Either:
dataGridView1.CellClick += new DataGridViewCellEventHandler(dataGridView1_CellClick);
or:
dataGridView1.CellContentClick += new DataGridViewCellEventHandler(dataGridView1_CellContentClick);
And then add the handler method (either dataGridView1_CellClick or dataGridView1_CellContentClick) shown in the various answers above.
Note: VB.NET is different from C# in this respect, because we can simply add a Handles clause to our method's signature or issue an AddHandler statement as described in the Microsoft doc's "How to: Call an Event Handler in Visual Basic"
You should initialize yours recordings. You are passing to adapter null
ArrayList<String> recordings = null; //You are passing this null
When I'd like to view incoming connections from our application servers to the database I use the following command:
SELECT username FROM v$session
WHERE username IS NOT NULL
ORDER BY username ASC;
Simple, but effective.
Vector was part of 1.0 -- the original implementation had two drawbacks:
1. Naming: vectors are really just lists which can be accessed as arrays, so it should have been called ArrayList
(which is the Java 1.2 Collections replacement for Vector
).
2. Concurrency: All of the get()
, set()
methods are synchronized
, so you can't have fine grained control over synchronization.
There is not much difference between ArrayList
and Vector
, but you should use ArrayList
.
From the API doc.
As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework. Unlike the new collection implementations, Vector is synchronized.
Since I found this via google searching for how to format json to make it more readable for troubleshooting.
ob_start() ; print_r( $json ); $ob_out=ob_get_contents(); ob_end_clean(); echo "\$json".str_replace( '}', "}\n", $ob_out );
The following code reads 4 bytes from array
(a byte[]
) at position index
and returns a int
. I tried out most of the code from the other answers on Java 10 and some other variants I dreamed up.
This code used the least amount of CPU time but allocates a ByteBuffer
until Java 10's JIT gets rid of the allocation.
int result;
result = ByteBuffer.
wrap(array).
getInt(index);
This code is the best performing code that does not allocate anything. Unfortunately, it consumes 56% more CPU time compared to the above code.
int result;
short data0, data1, data2, data3;
data0 = (short) (array[index++] & 0x00FF);
data1 = (short) (array[index++] & 0x00FF);
data2 = (short) (array[index++] & 0x00FF);
data3 = (short) (array[index++] & 0x00FF);
result = (data0 << 24) | (data1 << 16) | (data2 << 8) | data3;
create shake.xml in anim folder

android:fromXDelta="0"
android:toXDelta="10"

and cycle.xml in anim folder
<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
android:cycles="4" />
now add animation on your code
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);
If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value
What you have is correct, but this is more consice:

Answer:
If using directories or application with IIS or a reverse proxy,<br/> set the Swagger endpoint to a relative path using the ./ prefix. For example,<br/> ./swagger/v1/swagger.json. Using /swagger/v1/swagger.json instructs the app to<br/>look for the JSON file at the true root of the URL (plus the route prefix, if used). For example, use http://localhost:<br/><br/><port>/<route_prefix>/swagger/v1/swagger.json instead of http://localhost:<br/><port>/<virtual_directory>/<route_prefix>/swagger/v1/swagger.json.<br/>
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
// Enable middleware to serve generated Swagger as a JSON endpoint.
app.UseSwagger();
app.UseSwaggerUI(c =>
{
//c.SwaggerEndpoint("/swagger/v1/swagger.json", "MyAPI V1");
//Add dot in front of swagger path so that it takes relative path in server
c.SwaggerEndpoint("./swagger/v1/swagger.json", "MyAPI V1");
