You can group your dependencies within a different project with packaging pom
as described by Sonatypes Best Practices:
<project>
<modelVersion>4.0.0</modelVersion>
<artifactId>base-dependencies</artifactId>
<groupId>es.uniovi.innova</groupId>
<version>1.0.0</version>
<packaging>pom</packaging>
<dependencies>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>
</dependencies>
</project>
and reference them from your parent-pom (watch the dependency <type>pom</type>
):
<project>
<modelVersion>4.0.0</modelVersion>
<artifactId>base</artifactId>
<groupId>es.uniovi.innova</groupId>
<version>1.0.0</version>
<packaging>pom</packaging>
<dependencies>

<artifactId>base-dependencies</artifactId>
<groupId>es.uniovi.innova</groupId>
<version>1.0.0</version>
<type>pom</type>
</dependency>
</dependencies>
</project>
Your child-project inherits this parent-pom as before. But now, the mail dependency can be excluded in the child-project within the dependencyManagement
block:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>test</groupId>

Catch the exception that happens to be a parent class in the exception hierarchy. This is of course, bad practice. In your case, the common parent exception happens to be the Exception class, and catching any exception that is an instance of Exception, is indeed bad practice - exceptions like NullPointerException are usually programming errors and should usually be resolved by checking for null values.
You can use a constant (i.e. a static, final variable) as the parameter for an annotation. As a quick example, I use something like this fairly often:
import org.junit.Test;
import static org.junit.Assert.*;
public class MyTestClass
{
private static final int TEST_TIMEOUT = 60000; // one minute per test
@Test(timeout=TEST_TIMEOUT)
public void testJDK()
{
assertTrue("Something is very wrong", Boolean.TRUE);
}
}
Note that it's possible to pass the TEST_TIMEOUT
constant straight into the annotation.
Offhand, I don't recall ever having tried this with an array, so you may be running into some issues with slight differences in how arrays are represented as annotation parameters compared to Java variables? But as for the other part of your question, you could definitely use a constant String without any problems.
EDIT: I've just tried this with a String array, and didn't run into the problem you mentioned - however the compiler did tell me that the "attribute value must be constant" despite the array being defined as public static final String[]
. Perhaps it doesn't like the fact that arrays are mutable? Hmm...

You can create an alias for it. I am using ZSH shell with Oh-my-Zsh and here is an handy alias:
# delete and re-init git
# usage: just type 'gdelinit' in a local repository
alias gdelinit="trash .git && git init"
I am using Trash to trash the .git
folder since using rm
is really dangerous:
trash .git
Then I am re-initializing the git repo:
git init
Yes. Youtube API is the best resource for this.
There are 3 way to embed a video:
<iframe>
tagsDEPRECATED
I think you are looking for the second one of them:
The HTML and JavaScript code below shows a simple example that inserts a YouTube player into the page element that has an id value of ytplayer. The onYouTubePlayerAPIReady() function specified here is called automatically when the IFrame Player API code has loaded. This code does not define any player parameters and also does not define other event handlers.
<div id="ytplayer"></div>
<script>
// Load the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Replace the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE'
});
}
</script>
Here are some instructions where you may take a look when starting using the API.
An embed example without using iframe
is to use <object>
tag:
<object width="640" height="360">
<param name="movie" value="http://www.youtube.com/embed/yt-video-id?html5=1&rel=0&hl=en_US&version=3"/
<param name="allowFullScreen" value="true"/>
<param name="allowscriptaccess" value="always"/>
<embed width="640" height="360" src="http://www.youtube.com/embed/yt-video-id?html5=1&rel=0&hl=en_US&version=3" class="youtube-player" type="text/html" allowscriptaccess="always" allowfullscreen="true"/>
</object>
(replace yt-video-id
with your video id)
I'm going to show you an example that will help you to understand why it's important.
Such as you have some Box Widgets and you want to show some hidden content inside every single widget. You can do this easily when you have a different CSS class for the single widget but when it has the same class how can you do that?
Actually, that's why we use $(this)

OMG I Got A Quick File Move Command form CMD
1)Command will move All Files and Sub Folders into another location in 1 second .
check command
C:\user>move "your source path " "your destination path"
Hint : For move all Files and Sub folders
C:\user>move "f:\wamp\www" "f:\wapm_3.2\www\old Projects"
you can see that it's before i try some other code that was not working due to more than 1 files and folder was there. when i try to execute code that is under line by red color then all folder move in 1 second.
now check this image. here Total 6.7GB data moved in 1 second... you can check date of post and move as well as Folder name.
i will soon make a windows app that will do same..
It seems I'm kind of late :), but the discussion is pretty interesting so.. here it goes... Assuming you want to build a error handler, and you're using your own exception handler class like:
function errorHandler(error){
this.errorMessage = error;
}
errorHandler.prototype. displayErrors = function(){
throw new Error(this.errorMessage);
}
And you're wrapping your code like this:
try{
if(condition){
//whatever...
}else{
throw new errorHandler('Some Error Message');
}
}catch(e){
e.displayErrors();
}
Most probably you'll have the error handler in a separate .js file.
You'll notice that in firefox or chrome's error console the code line number(and file name) showed is the line(file) that throws the 'Error' exception and not the 'errorHandler' exception wich you really want in order to make debugging easy. Throwing your own exceptions is great but on large projects locating them can be quite an issue, especially if they have similar messages. So, what you can do is to pass a reference to an actual empty Error object to your error handler, and that reference will hold all the information you want( for example in firefox you can get the file name, and line number etc.. ; in chrome you get something similar if you read the 'stack' property of the Error instance). Long story short , you can do something like this:
function errorHandler(error, errorInstance){
this.errorMessage = error;
this. errorInstance = errorInstance;
}
errorHandler.prototype. displayErrors = function(){
//add the empty error trace to your message
this.errorMessage += ' stack trace: '+ this. errorInstance.stack;
throw new Error(this.errorMessage);
}
try{
if(condition){
//whatever...
}else{
throw new errorHandler('Some Error Message', new Error());
}
}catch(e){
e.displayErrors();
}
Now you can get the actual file and line number that throwed you custom exception.

Another alternative is to use the Underscore.js library.
Note that _.pick()
and _.omit()
both return a copy of the object and don't directly modify the original object. Assigning the result to the original object should do the trick (not shown).
Reference: link _.pick(object, *keys)
Return a copy of the object, filtered to only have values for the whitelisted keys (or array of valid keys).
var myJSONObject =
{"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"};
_.pick(myJSONObject, "ircEvent", "method");
=> {"ircEvent": "PRIVMSG", "method": "newURI"};
Reference: link _.omit(object, *keys)
Return a copy of the object, filtered to omit the blacklisted keys (or array of keys).
var myJSONObject =
{"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"};
_.omit(myJSONObject, "regex");
=> {"ircEvent": "PRIVMSG", "method": "newURI"};
For arrays, _.filter()
and _.reject()
can be used in a similar manner.
this
is the DOM element on which the event was hooked. this.id
is its ID. No need to wrap it in a jQuery instance to get it, the id
property reflects the attribute reliably on all browsers.
$("select").change(function() {
alert("Changed: " + this.id);
}
You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event
object's target
property:
$("#container").change(function(event) {
alert("Field " + event.target.id + " changed");
});
(jQuery ensures that the change
event bubbles, even on IE where it doesn't natively.)
As far as I know, the only way to get the name would be
Mode.mode1.name();
If you really need it this way, however, you could do:
public enum Modes {
mode1 ("Mode1"),
mode2 ("Mode2"),
mode3 ("Mode3");
private String name;
private Modes(String s) {
name = s;
}
}
You can find ===
and !==
operators in several other dynamically-typed languages as well. It always means that the two values are not only compared by their "implied" value (i.e. either or both values might get converted to make them comparable), but also by their original type.
That basically means that if 0 == "0"
returns true, 0 === "0"
will return false because you are comparing a number and a string. Similarly, while 0 != "0"
returns false, 0 !== "0"
returns true.
You can try to use underscore.js
First convert the lines in arrays using the toArray function :
var letters = _.toArray(a,b,c,d);
var numbers = _.toArray(1,2,3,4);
Then object the arrays together using the object function :
var json = _.object(letters, numbers);
By then, the json var should contain something like :
{"a": 1,"b": 2,"c": 3,"d": 4}
f = open('file.txt','r')
for line in f:
myNames.append(line.strip()) # We don't want newlines in our list, do we?
I would also recommend using the Perl debugger.
However, since you asked about something like shell's -x
have a look at the Devel::Trace module which does something similar.
In my case, the Windows Firewall
was blocking Android Studio (i.e. java.exe
from Android Studio's jre/bin
folder) from connecting to sites and downloading data. After Windows asked me if I wanted to allow the app through the firewall, I had to do a manual sync File -> Sync project with gradle files
. After that, things were still disfunctional, a manual download of an SDK version 28 was necessary from Tools -> SDK Manager
.
This solution caters for http, https and the other normal url type special characters :
import re
def remove_urls (vTEXT):
vTEXT = re.sub(r'(https|http)?:\/\/(\w|\.|\/|\?|\=|\&|\%)*\b', '', vTEXT, flags=re.MULTILINE)
return(vTEXT)
print( remove_urls("this is a test https://sdfs.sdfsdf.com/sdfsdf/sdfsdf/sd/sdfsdfs?bob=%20tree&jef=man lets see this too https://sdfsdf.fdf.com/sdf/f end"))
Verify current version of python by:
$ python --version
then check python is symbolic link to which file.
$ ll /usr/bin/python
Output Ex:
lrwxrwxrwx 1 root root 9 Jun 16 2014 /usr/bin/python -> python2.7*
Check other available versions of python:
$ ls /usr/bin/python*
Output Ex:
/usr/bin/python /usr/bin/python2.7-config /usr/bin/python3.4 /usr/bin/python3.4m-config /usr/bin/python3.6m /usr/bin/python3m
/usr/bin/python2 /usr/bin/python2-config /usr/bin/python3.4-config /usr/bin/python3.6 /usr/bin/python3.6m-config /usr/bin/python3m-config
/usr/bin/python2.7 /usr/bin/python3 /usr/bin/python3.4m /usr/bin/python3.6-config /usr/bin/python3-config /usr/bin/python-config
If want to change current version of python to 3.6 version edit file ~/.bashrc:
vim ~/.bashrc
add below line in the end of file and save:
alias python=/usr/local/bin/python3.6
To install pip for python 3.6
$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip
On Success, check current version of pip:
$ pip3 -V
Output Ex:
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)
I've tested a good product for that: AlwaysUp. Not free but they have a 30 days trial period so you can give it a try...
You can try
echo implode(', ', (array)$ret);
Just another approach:
string mystr = "hello";
MessageBox.show(mystr.Substring(0, 1));
Use DATE_FORMAT
from Date Conversions:
In your initializer:
DateTime::DATE_FORMATS[:my_date_format] = "%a %b %d %H:%M:%S %Z %Y"
In your view:
date = DateTime.parse("2011-05-19 10:30:14")
date.to_formatted_s(:my_date_format)
date.to_s(:my_date_format)
jquery validation plugin version work fine v1.15.0 but v1.17.0 not work for me.
$(document).find('#add_patient_form').validate({
ignore: [],
rules:{
'email[]':
{
required:true,
},
},
messages:{
'email[]':
{
'required':'Required'
},
},
});
you can either use
echo '<a href="'.$link_address.'">Link</a>';
or
echo "<a href=\"$link_address\">Link</a>';
if you use double quotes you can insert the variable into the string and it will be parsed.
"Access violation reading location 0x00000000" means that you're derefrencing a pointer that hasn't been initialized and therefore has garbage values. Those garbage values could be anything, but usually it happens to be 0
and so you try to read from the memory address 0x0
, which the operating system detects and prevents you from doing.
Check and make sure that the array invaders[]
is what you think it should be.
Also, you don't seem to be updating i
ever - meaning that you keep placing the same Invader
object into location 0
of invaders[]
at every loop iteration.
You can even simply add the parameters to the end of the url:
$http.get('path/to/script.php?param=hello').success(function(data) {
alert(data);
});
Paired with script.php:
<? var_dump($_GET); ?>
Resulting in the following javascript alert:
array(1) {
["param"]=>
string(4) "hello"
}
Kendo UI provides the best and ultimate collection of JavaScript UI components with libraries for jQuery, Angular, React, and Vue. You can quickly build eye-catching, high-performance, responsive web applications regardless of your JavaScript framework choice. Here is a timepicker UI component from them:
Also below is an alternate and a simple solution
<!--Css-->
<link href="css/timepicker.css" type="text/css" rel="stylesheet" />
<!--Html-->
<div class="row">
<div class="col">
<label class="label-in">Time</label>
<input class="timepicker" id="event-time" type="text" value="" required="">
</div>
</div>
<!--Script-->
<script src="Scripts/ClockPicker.js"></script>
<script>
$('.timepicker').timepicker({
});
</script>
Here is yet another popular framework Bootstrap Time Picker from mdbootstrap
Use the INTERVAL
type to it. E.g:
--yesterday
SELECT NOW() - INTERVAL '1 DAY';
--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;
Then you can do the following on your query:
SELECT
org_id,
count(accounts) AS COUNT,
((date_at) - INTERVAL '1 DAY') AS dateat
FROM
sourcetable
WHERE
date_at <= now() - INTERVAL '130 DAYS'
GROUP BY
org_id,
dateat;
You can append multiple operands. E.g.: how to get last day of current month?
SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';
You can also create an interval using make_interval
function, useful when you need to create it at runtime (not using literals):
SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);
It appears that Chrome now ignores autocomplete="off"
unless it is on the <form autocomplete="off">
tag.
You can use either foreign key on many side of OneToMany
relation (i.e. ManyToOne
relation) or use ManyToMany
(on any side) with unique constraint.
You could try powershell. There are get-content and set-content commandlets build in that you could use.

The copy
command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.
Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).
I tried a variation of your command as follows in SQL*Plus (with no errors):
copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;
After I executed the above statement, I also truncate the new_emp table and executed this command:
copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;
With SQL Developer, you could do the following to perform a similar approach to copying objects:
On the tool bar, select Tools>Database copy.
Identify source and destination connections with the copy options you would like.
For object type, select table(s).
The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).
Maybe this post is too old but it may help as a suggestion for someone looking around on this : Instead of using:
print_r($this->pdo->errorInfo());
Use PHP implode() function:
echo 'Error occurred:'.implode(":",$this->pdo->errorInfo());
This should print the error code, detailed error information etc. that you would usually get if you were using some SQL User interface.
Hope it helps
I had the same problem, tried setting path variables and everything. What SDK manager needs is not the JDK, but the actual Java SE end user crap. Go to http://www.java.com/en/download/ie_manual.jsp?locale=en and download that. As soon as I finished installing that, it worked like a charm
You need to use
$(this).parents('form').submit()
I'd recommend you yo use an out-of-the-box solution. Given that the development of a workflow engine requires a vast amount of resources and time, a ready-made engine is a better option. Have a look at Workflow Engine. It's a lightweight component that enables you to add custom executable workflows of any complexity to any Java solutions.
Plain and simple, to fetch the submodules:
git submodule update --init --recursive
And now proceed updating them to the latest master branch (for example):
git submodule foreach git pull origin master
I hope this query will help you
INSERT INTO `dTable` (`field1`, `field2`)
SELECT field1, field2 FROM `sTable`
WHERE `sTable`.`field1` NOT IN (SELECT `field1` FROM `dTable`)
This is a real-world example.
While working with GWT-Bootstrap V2, it will inject some CSS file, which will override my CSS styles. In order to make my properties to be not overridden, I used !important
.
For deleting all files from directory say "C:\Example"
File file = new File("C:\\Example");
String[] myFiles;
if (file.isDirectory()) {
myFiles = file.list();
for (int i = 0; i < myFiles.length; i++) {
File myFile = new File(file, myFiles[i]);
myFile.delete();
}
}
If you're proficient in C# and Visual Studio, you might try IKVM. It's not exactly what you were asking for, but will certainly help with bridging the gap by allowing you to call into Java libraries from C# and vise versa. You can use it in Visual Studio, but it also has first class support in MonoDevelop.
All of the above work, but also have to work around a problem (escapes and special characters) that doesn't need to occur in the first place: Special characters when the variable is expanded by the shell. Just don't do that (variable expansion) in the first place. Use the variable directly, without expansion.
Also, if your variable contains a secret and you want to copy that secret into a file, you might want to not have expansion in the command line as tracing/command echo of the shell commands might reveal the secret. Means, all answers which use $var
in the command line may have a potential security risk by exposing the variable contents to tracing and logging of the shell.
Use this:
printenv var >file
That means, in case of the OP question:
printenv var >"$destfile"
Note: variable names are case sensitive.
If your Session instance is null and your in an 'ashx' file, just implement the 'IRequiresSessionState' interface.
This interface doesn't have any members so you just need to add the interface name after the class declaration (C#):
public class MyAshxClass : IHttpHandler, IRequiresSessionState
Use 51Degrees.com device detection solution to detect browser name, vendor and version.
First, follow the 4-step guide to incorporate device detector in to your project. When I say incorporate I mean download archive with PHP code and database file, extract them and include 2 files. That's all there is to do to incorporate.
Once that's done you can use the following properties to get browser information:
$_51d['BrowserName'] - Gives you the name of the browser (Safari, Molto, Motorola, MStarBrowser etc).
$_51d['BrowserVendor'] - Gives you the company who created browser.
$_51d['BrowserVersion'] - Version number of the browser
Conceptually it's quite simple. Depending on which language you're using you will be able to convert those dates into some reference 32 or 64 bit integer, typically representing seconds since epoch (1 January 1970) otherwise known as "Unix time" or milliseconds since some other arbitrary date. Simply generate a random 32 or 64 bit integer between those two values. This should be a one liner in any language.
On some platforms you can generate a time as a double (date is the integer part, time is the fractional part is one implementation). The same principle applies except you're dealing with single or double precision floating point numbers ("floats" or "doubles" in C, Java and other languages). Subtract the difference, multiply by random number (0 <= r <= 1), add to start time and done.
You can find it at link:
C:\Windows\assembly\GAC_MSIL\Microsoft.Office.Interop.Word\15.0.0.0__71e9bce111e9429c\Microsoft.Office.Interop.Word.dll
Browse it then add references
As mentioned @Value
does the job and it is quite flexible as you can have spring EL in it.
Here are some examples, which could be helpful:
//Build and array from comma separated parameters
//Like currency.codes.list=10,11,12,13
@Value("#{'${currency.codes.list}'.split(',')}")
private List<String> currencyTypes;
Another to get a set
from a list
//If you have a list of some objects like (List<BranchVO>)
//and the BranchVO has areaCode,cityCode,...
//You can easily make a set or areaCodes as below
@Value("#{BranchList.![areaCode]}")
private Set<String> areas;
You can also set values for primitive types.
@Value("${amount.limit}")
private int amountLimit;
You can call static methods:
@Value("#{T(foo.bar).isSecurityEnabled()}")
private boolean securityEnabled;
You can have logic
@Value("#{T(foo.bar).isSecurityEnabled() ? '${security.logo.path}' : '${default.logo.path}'}")
private String logoPath;
Do you mean something like this? JSFiddle

let image = UIImage(named: "name") as UIImage?

System.out.println(letter);
}
Note: This solution is better for older versions of JSTL. For versions greater then 1.1 I recommend using fn:length(MyBean.somelist)
as suggested by Bill James.
This article has some more detailed information, including another possible solution;
The problem is that we are trying to invoke the list's size method (which is a valid LinkedList method), but it's not a JavaBeans-compliant getter method, so the expression list.size-1 cannot be evaluated.
There are two ways to address this dilemma. First, you can use the RT Core library, like this:
<c_rt:out value='<%= list[list.size()-1] %>'/>
Second, if you want to avoid Java code in your JSP pages, you can implement a simple wrapper class that contains a list and provides access to the list's size property with a JavaBeans-compliant getter method. That bean is listed in Listing 2.25.
The problem with c_rt method is that you need to get the variable from request manually, because it doesn't recognize it otherwise. At this point you are putting in a lot of code for what should be built in functionality. This is a GIANT flaw in the EL.
I ended up using the "wrapper" method, here is the class for it;
public class CollectionWrapper {
Collection collection;
public CollectionWrapper(Collection collection) {
this.collection = collection;
}
public Collection getCollection() {
return collection;
}
public int getSize() {
return collection.size();
}
}
A third option that no one has mentioned yet is to put your list size into the model (assuming you are using MVC) as a separate attribute. So in your model you would have "someList" and then "someListSize". That may be simplest way to solve this issue.
There is no full-proof method to prevent your images being downloaded/stolen.
But, some solutions like: watermarking your images(from client side or server side), implement a background image, disable/prevent right clicks, slice images into small pieces and then present as a complete image to browser, you can also use flash to show images.
Personally, recommended methods are: Watermarking and flash. But it is a difficult and almost impossible mission to accomplish. As long as user is able to "see" that image, means they take "screenshot" to steal the image.
If you want to keep the row with the lowest id value:
DELETE n1 FROM 'yourTableName' n1, 'yourTableName' n2 WHERE n1.id > n2.id AND n1.email = n2.email
If you want to keep the row with the highest id value:
DELETE n1 FROM 'yourTableName' n1, 'yourTableName' n2 WHERE n1.id < n2.id AND n1.email = n2.email
I tried using phyatt's AspectRatioPixmapLabel
class, but experienced a few problems:
QLabel::setPixmap(...)
inside the resizeEvent method, because QLabel
actually calls updateGeometry
inside setPixmap
, which may trigger resize events...heightForWidth
seemed to be ignored by the containing widget (a QScrollArea
in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
QLabel
's implementation of minimumSizeHint()
does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite itThat said, here is my solution. I found that I could just use setScaledContents(true)
and let QLabel
handle the resizing.
Of course, this depends on the containing widget / layout honoring the heightForWidth
.
aspectratiopixmaplabel.h
#ifndef ASPECTRATIOPIXMAPLABEL_H
#define ASPECTRATIOPIXMAPLABEL_H
#include <QLabel>
#include <QPixmap>
class AspectRatioPixmapLabel : public QLabel
{
Q_OBJECT
public:
explicit AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent = 0);
virtual int heightForWidth(int width) const;
virtual bool hasHeightForWidth() { return true; }
virtual QSize sizeHint() const { return pixmap()->size(); }
virtual QSize minimumSizeHint() const { return QSize(0, 0); }
};
#endif // ASPECTRATIOPIXMAPLABEL_H
aspectratiopixmaplabel.cpp
#include "aspectratiopixmaplabel.h"
AspectRatioPixmapLabel::AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent) :
QLabel(parent)
{
QLabel::setPixmap(pixmap);
setScaledContents(true);
QSizePolicy policy(QSizePolicy::Maximum, QSizePolicy::Maximum);
policy.setHeightForWidth(true);
this->setSizePolicy(policy);
}
int AspectRatioPixmapLabel::heightForWidth(int width) const
{
if (width > pixmap()->width()) {
return pixmap()->height();
} else {
return ((qreal)pixmap()->height()*width)/pixmap()->width();
}
}
The accepted answer is spot on the basic definition of horizontal vs vertical scaling. But unlike the common belief that horizontal scaling of databases is only possible with Cassandra, MongoDB, etc I would like to add that horizontal scaling is also very much possible with any traditional RDMS; that too without using any third party solutions.
I know of many companies, specially SaaS based companies that do this. This is done using simple application logic. You basically take a set of users and divide them over multiple DB servers. So for example, you would typically have a "meta" database/table that would store clients, DB server/connection strings, etc and a table that stores client/server mapping.
Then simply direct requests from each client to the DB server they are mapped to.
Now some may say this is akin to horizontal partitioning and not "true" horizontal scaling and they will be right in some ways. But the end result is that you have scaled your DB over multiple Db servers.
The only difference between the two approaches to horizontal scaling is that one approach (MongoDB, etc) the scaling is done by the DB software itself. In that sense you are "buying" the scaling. In the other approach (for RDBMS horizontal scaling), the scaling is built by application code/logic.
Here is my suggestion:
DECLARE @FIELDS VARCHAR(MAX), @NUM INT
--DROP TABLE #FIELD_LIST
SET @NUM = 1
SET @FIELDS = ''
SELECT
'SEQ' = IDENTITY(int,1,1) ,
COLUMN_NAME
INTO #FIELD_LIST
FROM Req.INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = N'new340B'
WHILE @NUM <= (SELECT COUNT(*) FROM #FIELD_LIST)
BEGIN
SET @FIELDS = @FIELDS + ',' + (SELECT COLUMN_NAME FROM #FIELD_LIST WHERE SEQ = @NUM)
SET @NUM = @NUM + 1
END
SET @FIELDS = RIGHT(@FIELDS,LEN(@FIELDS)-1)
EXEC('SELECT ' + @FIELDS + ', COUNT(*) AS QTY FROM [Req].[dbo].[new340B] GROUP BY ' + @FIELDS + ' HAVING COUNT(*) > 1 ')
Other than the append
function, if by "multiple values" you mean another list, you can simply concatenate them like so.
>>> a = [1,2,3]
>>> b = [4,5,6]
>>> a + b
[1, 2, 3, 4, 5, 6]
If x^2 and y^2 were expressions already given in the variable squared, this solves the problem:
labNames <- c('xLab','yLab')
squared <- c(expression('x'^2), expression('y'^2))
xlab <- eval(bquote(expression(.(labNames[1]) ~ .(squared[1][[1]]))))
ylab <- eval(bquote(expression(.(labNames[2]) ~ .(squared[2][[1]]))))
plot(c(1:10), xlab = xlab, ylab = ylab)
Please note the [[1]] behind squared[1]. It gives you the content of "expression(...)" between the brackets without any escape characters.
Use commented if block to prevent add values which has already in array if you use button click or something to run the insertion

Update Angular CLI for a workspace (Local)
npm install --save -dev @angular/cli@latest
Note: Make sure to install the global version using the command with ‘-g’ is if it installed properly.
npm install -g @angular/cli@latest
Run Update command to get a list of all dependencies required to be upgraded
ng update
Next Run update command as below for each individual Angular core package
ng update @angular/cli @angular/core
However, I had to add ‘–force’ and ‘–allow-dirty’ flags command additionally to fix all other pending issues.
ng update @angular/cli @angular/core --allow-dirty --force
for item in array: array2.append (item)
Or, in this case:
array2 += array
The problem is caused by accessing an attribute with the hibernate session closed. You have not a hibernate transaction in the controller.
Possible solutions:
Do all this logic, in the service layer, (with the @Transactional), not in the controller. There should be the right place to do this, it is part of the logic of the app, not in the controller (in this case, an interface to load the model). All the operations in the service layer should be transactional. i.e.: Move this line to the TopicService.findTopicByID method:
Collection commentList = topicById.getComments();
Use 'eager' instead of 'lazy'. Now you are not using 'lazy' .. it is not a real solution, if you want to use lazy, works like a temporary (very temporary) workaround.
In general, the best solution is the 1.

label.font = UIFont.boldSystemFont(ofSize: 16.0)
You need upper case property names in your structs in order to be used by the json packages.
Upper case property names are exported properties
. Lower case property names are not exported.
You also need to pass the your data object by reference (&data

I also solved my problem with Mosh's answer and I thought PeterB's answer was a bit of since it used an enum as foreign key. Remember that you will need to add a new migration after adding this code.
I can also recommend this blog post for other solutions:
http://www.kianryan.co.uk/2013/03/orphaned-child/
Code:
public class Child
{
[Key, Column(Order = 0), DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string Heading { get; set; }
//Add other properties here.
[Key, Column(Order = 1)]
public int ParentId { get; set; }
public virtual Parent Parent { get; set; }
}

$ npm i --save @fortawesome/fontawesome
$ npm i --save @fortawesome/react-fontawesome
$ npm i --save @fortawesome/fontawesome-free-solid
$ npm i --save @fortawesome/fontawesome-free-regular
$ npm i --save @fortawesome/fontawesome-svg-core
then in your component
import React, { Component } from 'react';
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome'
import { faCheckSquare, faCoffee } from '@fortawesome/fontawesome-free-solid'
import './App.css';
class App extends Component {

export default App;
If you want to return some value then wrap your statement in function
function my_function(){
return my_thing;
}
Problem is with the statement on the 1st line if you are trying to use PHP
var ask = confirm ('".$message."');
IF you are trying to use PHP you should use
var ask = confirm (<?php echo "'".$message."'" ?>); //now message with be the javascript string!!

You can use ES7 statics:
npm install babel-preset-stage-0
And then add "stage-0"
to .babelrc presets:
{
"presets": ["es2015", "react", "stage-0"]
}
Afterwards, you go
class Component extends React.Component {
static foo = 'bar';
static baz = {a: 1, b: 2}
}
And then you use them like this:
Component.foo
You can send the FormData object in ajax request using the following code,
$("form#formElement").submit(function(){
var formData = new FormData($(this)[0]);
});
This is very similar to the accepted answer but an actual answer to the question topic. This will submit the form elements automatically in the FormData and you don't need to manually append the data to FormData variable.
The ajax method looks like this,
$("form#formElement").submit(function(){
var formData = new FormData($(this)[0]);
//append some non-form data also
formData.append('other_data',$("#someInputData").val());
$.ajax({
type: "POST",
url: postDataUrl,
data: formData,
processData: false,
contentType: false,
dataType: "json",
success: function(data, textStatus, jqXHR) {
//process data
},
error: function(data, textStatus, jqXHR) {
//process error msg
},
});
You can also manually pass the form element inside the FormData object as a parameter like this
var formElem = $("#formId");
var formdata = new FormData(formElem[0]);
Hope it helps. ;)
Suppose i have .config file in console app and now am getting like below.
Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName + "\\YourFolderName\\log4net.config";
The most efficient is to use StringBuilder, like so:
StringBuilder sb = new StringBuilder();
sb.Append("string1");
sb.Append("string2");
...etc...
String strResult = sb.ToString();
@jonezy: String.Concat is fine if you have a couple of small things. But if you're concatenating megabytes of data, your program will likely tank.
Yes it stops execution so this is generally preferable to HAVING COUNT(*) > 0
which often won't.
With EXISTS
if you look at the execution plan you will see that the actual number of rows coming out of table1
will not be more than 1 irrespective of number of matching records.
In some circumstances SQL Server can convert the tree for the COUNT
query to the same as the one for EXISTS
during the simplification phase (with a semi join and no aggregate operator in sight) an example of that is discussed in the comments here.
For more complicated sub trees than shown in the question you may occasionally find the COUNT
performs better than EXISTS
however. Because the semi join needs only retrieve one row from the sub tree this can encourage a plan with nested loops for that part of the tree - which may not work out optimal in practice.
In Java 8+ you achieve this with the help of streams allMatch method.
For primitive:
int[] k = new int[3];
Arrays.stream(k).allMatch(element -> element != 0)
For Object:
Objects[] k = new Objects[3];
Arrays.stream(k).allMatch(Objects::nonNull)
This was pretty straight forward and worked for me, in terminal:
$echo "export PATH=$PATH:/path/to/whatever" >> .bash_profile #replace "/path/to/whatever" with the location of what you want to add to your bash profile, i.e: $ echo "export PATH=$PATH:/usr/local/Cellar/nginx/1.0.12/sbin" >> .bash_profile
$. .bash_profile #restart your bash shell

Based on the Roman's most upvoted comment above, here is my implementation, Including "download as" and "retries" mechanism:
def download(url: str, file_path='', attempts=2):
"""Downloads a URL content into a file (with large file support by streaming)
:param url: URL to download
:param file_path: Local file name to contain the data downloaded
:param attempts: Number of attempts
:return: New file path. Empty string if the download failed
"""
if not file_path:
file_path = os.path.realpath(os.path.basename(url))
logger.info(f'Downloading {url} content to {file_path}')
url_sections = urlparse(url)
if not url_sections.scheme:
logger.debug('The given url is missing a scheme. Adding http scheme')
url = f'http://{url}'
logger.debug(f'New url: {url}')
for attempt in range(1, attempts+1):
try:
if attempt > 1:
time.sleep(10) # 10 seconds wait time between downloads
with requests.get(url, stream=True) as response:
response.raise_for_status()
with open(file_path, 'wb') as out_file:
for chunk in response.iter_content(chunk_size=1024*1024): # 1MB chunks
out_file.write(chunk)
logger.info('Download finished successfully')
return file_path
except Exception as ex:
logger.error(f'Attempt #{attempt} failed with error: {ex}')
return ''
My conclusion is that(Tested on 12c):
thus :
SELECT {T / t} FROM (SELECT 1 AS T FROM DUAL); -- Correct
SELECT "tEST" FROM (SELECT 1 AS "tEST" FROM DUAL); -- Correct
SELECT {"TEST" / tEST} FROM (SELECT 1 AS "tEST" FROM DUAL ); -- Incorrect
SELECT test_value AS "doggy" FROM test ORDER BY "doggy"; --Correct
SELECT test_value AS "doggy" FROM test WHERE "doggy" IS NOT NULL; --You can not do this, column alias not supported in WHERE & HAVING
SELECT * FROM test "doggy" WHERE "doggy".test_value IS NOT NULL; -- Do not use AS preceding table alias
So, the reason why USING AS AND "" causes problem is NOT AS
Note: "" double quotes are required if alias contains space OR if it contains lower-case characters and MUST show-up in Result set as lower-case chars. In all other scenarios its OPTIONAL and can be ignored.

videoView.post {

This can be achieved by using constructor function instead of literal
var o = new function() {
this.foo = "it";
this.bar = this.foo + " works"
}
alert(o.bar)
Inheritances Vs Composition.
Inheritances and composition both are used to re-usability and extension of class behavior.
Inheritances mainly use in a family algorithm programming model such as IS-A relation type means similar kind of object. Example.
These are belongs to Car family.
Composition represents HAS-A relationship Type.It shows the ability of an object such as Duster has Five Gears , Safari has four Gears etc. Whenever we need to extend the ability of an existing class then use composition.Example we need to add one more gear in Duster object then we have to create one more gear object and compose it to the duster object.
We should not make the changes in base class until/unless all the derived classes needed those functionality.For this scenario we should use Composition.Such as
class A Derived by Class B
Class A Derived by Class C
Class A Derived by Class D.
When we add any functionality in class A then it is available to all sub classes even when Class C and D don't required those functionality.For this scenario we need to create a separate class for those functionality and compose it to the required class(here is class B).
Below is the example:
// This is a base class
public abstract class Car
{
//Define prototype
public abstract void color();
public void Gear() {
Console.WriteLine("Car has a four Gear");
}
}
// Here is the use of inheritence
// This Desire class have four gears.
// But we need to add one more gear that is Neutral gear.
public class Desire : Car
{
Neutral obj = null;
public Desire()
{
// Here we are incorporating neutral gear(It is the use of composition).
// Now this class would have five gear.
obj = new Neutral();
obj.NeutralGear();
}
public override void color()
{
Console.WriteLine("This is a white color car");
}
}
// This Safari class have four gears and it is not required the neutral
// gear and hence we don't need to compose here.
public class Safari :Car{
public Safari()
{ }
public override void color()
{
Console.WriteLine("This is a red color car");
}
}
// This class represents the neutral gear and it would be used as a composition.
public class Neutral {
public void NeutralGear() {
Console.WriteLine("This is a Neutral Gear");
}
}
This header is defined in RFC 2183, so that would be the best place to start reading.
Permitted values are those registered with the Internet Assigned Numbers Authority (IANA); their registry of values should be seen as the definitive source.
I'm afraid not—the simulator shares whatever network connection the OS is using. I filed a Radar bug report about simulating network conditions a while back; you might consider doing the same.
In RSA crypto, when you generate a key pair, it's completely arbitrary which one you choose to be the public key, and which is the private key. If you encrypt with one, you can decrypt with the other - it works in both directions.
So, it's fairly simple to see how you can encrypt a message with the receiver's public key, so that the receiver can decrypt it with their private key.
A signature is proof that the signer has the private key that matches some public key. To do this, it would be enough to encrypt the message with that sender's private key, and include the encrypted version alongside the plaintext version. To verify the sender, decrypt the encrypted version, and check that it is the same as the plaintext.
Of course, this means that your message is not secret. Anyone can decrypt it, because the public key is well known. But when they do so, they have proved that the creator of the ciphertext has the corresponding private key.
However, this means doubling the size of your transmission - plaintext and ciphertext together (assuming you want people who aren't interested in verifying the signature, to read the message). So instead, typically a signature is created by creating a hash of the plaintext. It's important that fake hashes can't be created, so cryptographic hash algorithms such as SHA-2 are used.
So:
To add on nathan gonzalez answer, please note you need to assign the replaced object after calling replace
function since it is not a mutator function:
myString = myString.replace('username1','');

... so; likely drive letter in this example => /e
(or E:\ if you must), when knowing that C, G, and H are other things (in Windows).
I think you can use this code in order to have List of outgoing Addresses having a display Name (also different):
//1.The ACCOUNT
MailAddress fromAddress = new MailAddress("[email protected]", "my display name");
String fromPassword = "password";
//2.The Destination email Addresses
MailAddressCollection TO_addressList = new MailAddressCollection();
//3.Prepare the Destination email Addresses list
foreach (var curr_address in mailto.Split(new [] {";"}, StringSplitOptions.RemoveEmptyEntries))
{
MailAddress mytoAddress = new MailAddress(curr_address, "Custom display name");
TO_addressList.Add(mytoAddress);
}
//4.The Email Body Message
String body = bodymsg;
//5.Prepare GMAIL SMTP: with SSL on port 587
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
Timeout = 30000
};
//6.Complete the message and SEND the email:
using (var message = new MailMessage()
{
From = fromAddress,
Subject = subject,
Body = body,
})
{
message.To.Add(TO_addressList.ToString());
smtp.Send(message);
}

Check this CODEPEN to see how you can add colors and change their size.
It's all a matter of style. It's useful for debugging but otherwise it shouldn't be used in the final version of the program. It really doesn't matter on the memory issue because I'm sure that those guys who invented the system("pause") were anticipating that it'd be used often. In another perspective, computers get throttled on their memory for everything else we use on the computer anyways and it doesn't pose a direct threat like dynamic memory allocation, so I'd recommend it for debugging code, but nothing else.
The abs() in the while condition is needed, since, well, it controls the number of iterations (how would you define a negative number of iterations?). You can correct it by inverting the sign of the result if numb
is negative.
So this is the modified version of your code. Note I replaced the while loop with a cleaner for loop.
#get user input of numbers as variables
numa, numb = input("please give 2 numbers to multiply seperated with a comma:")
#standing variables
total = 0
#output the total
for count in range(abs(numb)):
total += numa
if numb < 0:
total = -total
print total
Your modifications are in a different branch than the original branch, which simplifies stuff because you get updates in one branch, and your work is in another branch.
Assuming the original branch is named master
, which the case in 99% of git repos, you have to fetch the state of origin, and merge origin/master
updates into your local master
:
git fetch origin
git checkout master
git merge origin/master
To switch to your branch, just do
git checkout branch1

I had the same error because I didn't issued a Let's Encrypt cert for the www.my-domain.com, only for my-domain.com
Issuing also for the www. and configuring the vhost to load certificates for www.my-domain.com before redirecting to https://my-domain.com did the trick.
If you want to insert HTML code inside existing page's tag use Jnerator. This tool was created specially for this goal.
Instead of writing next code
var htmlCode = '<ul class=\'menu-countries\'><li
class=\'item\'><img src=\'au.png\'></img><span>Australia </span></li><li
class=\'item\'><img src=\'br.png\'> </img><span>Brazil</span></li><li
class=\'item\'> <img src=\'ca.png\'></img><span>Canada</span></li></ul>';
var element = document.getElementById('myTag');
element.innerHTML = htmlCode;
You can write more understandable structure
var jtag = $j.ul({
class: 'menu-countries',
child: [
$j.li({ class: 'item', child: [
$j.img({ src: 'au.png' }),
$j.span({ child: 'Australia' })
]}),
$j.li({ class: 'item', child: [
$j.img({ src: 'br.png' }),
$j.span({ child: 'Brazil' })
]}),
$j.li({ class: 'item', child: [
$j.img({ src: 'ca.png' }),
$j.span({ child: 'Canada' })
]})
]
});
var htmlCode = jtag.html();
var element = document.getElementById('myTag');
element.innerHTML = htmlCode;
If you can NOT find the .m3u8
file you will need to do a couple of steps different.
1) Go to the network tab and sort by Media
2) You will see something here and select the first item. In my example, it's an mpd
file. then copy the Request URL.
3) Next, download the file using your favorite command line tool using the URL from step 2.
youtube-dl -f bestvideo+bestaudio https://url.com/destination/stream.mpd
4) Depending on the encoding you might have to join the audio and video files together but this will depend on a video by video case.
In Ruby on Rails I used this code, and it works perfectly:
req_profilepic = ActiveSupport::JSON.decode(open(URI.encode("https://graph.facebook.com/me/?fields=picture&type=large&access_token=#{fb_access_token}")))
profilepic_url = req_profilepic['picture']
For Angular9+, according to this, you can use:
.mat-select-panel {
background: red;
....
}
mat-select-content
as class name for the select list content. For its styling I would suggest four options.
1. Use ::ng-deep:
Use the /deep/ shadow-piercing descendant combinator to force a style down through the child component tree into all the child component views. The /deep/ combinator works to any depth of nested components, and it applies to both the view children and content children of the component. Use /deep/, >>> and ::ng-deep only with emulated view encapsulation. Emulated is the default and most commonly used view encapsulation. For more information, see the Controlling view encapsulation section. The shadow-piercing descendant combinator is deprecated and support is being removed from major browsers and tools. As such we plan to drop support in Angular (for all 3 of /deep/, >>> and ::ng-deep). Until then ::ng-deep should be preferred for a broader compatibility with the tools.
CSS:
::ng-deep .mat-select-content{
width:2000px;
background-color: red;
font-size: 10px;
}
2. Use ViewEncapsulation
... component CSS styles are encapsulated into the component's view and don't affect the rest of the application. To control how this encapsulation happens on a per component basis, you can set the view encapsulation mode in the component metadata. Choose from the following modes: .... None means that Angular does no view encapsulation. Angular adds the CSS to the global styles. The scoping rules, isolations, and protections discussed earlier don't apply. This is essentially the same as pasting the component's styles into the HTML.
None value is what you will need to break the encapsulation and set material style from your component. So can set on the component's selector:
Typscript:
import {ViewEncapsulation } from '@angular/core';
....
@Component({
....
encapsulation: ViewEncapsulation.None
})
CSS
.mat-select-content{
width:2000px;
background-color: red;
font-size: 10px;
}
3. Set class style in style.css
This time you have to 'force' styles with !important
too.
style.css
.mat-select-content{
width:2000px !important;
background-color: red !important;
font-size: 10px !important;
}
4. Use inline style
<mat-option style="width:2000px; background-color: red; font-size: 10px;" ...>
each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.
For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.
http:..../somelink?componentId=123
would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123
The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

document.getElementsByClassName('btn-pageMenu')
delivers a nodeList. You should use: document.getElementsByClassName('btn-pageMenu')[0].style.display
(if it's the first element from that list you want to change.
If you want to change style.display
for all nodes loop through the list:
var elems = document.getElementsByClassName('btn-pageMenu');
for (var i=0;i<elems.length;i+=1){
elems[i].style.display = 'block';
}
to be complete: if you use jquery it is as simple as:
?$('.btn-pageMenu').css('display'???????????????????????????,'block');??????
If you really need to use a secure foreach interface to iterate an object and make it reusable and clean with a npm module, then use this, https://www.npmjs.com/package/foreach-object
Ex:
import each from 'foreach-object';
const object = {
firstName: 'Arosha',
lastName: 'Sum',
country: 'Australia'
};
each(object, (value, key, object) => {
console.log(key + ': ' + value);
});
// Console log output will be:
// firstName: Arosha
// lastName: Sum
// country: Australia
Instead of rand()
, use newid()
, which is recalculated for each row in the result. The usual way is to use the modulo of the checksum. Note that checksum(newid())
can produce -2,147,483,648 and cause integer overflow on abs()
, so we need to use modulo on the checksum return value before converting it to absolute value.
UPDATE CattleProds
SET SheepTherapy = abs(checksum(NewId()) % 10000)
WHERE SheepTherapy IS NULL
This generates a random number between 0 and 9999.
If you want your anchor to still appear to be clickable:
$("a").removeAttr("href").css("cursor","pointer");
And if you wanted to remove the href from only anchors with certain attributes (eg ones that just have a hash mark as the href - this can be useful in asp.net)
$("a[href='#']").removeAttr("href").css("cursor","pointer");

MySQL stores DATETIME without timezone information. Let's say you store '2019-01-01 20:00:00' into a DATETIME field, when you retrieve that value you're expected to know what timezone it belongs to.
So in your case, when you store a value into a DATETIME field, make sure it is Tanzania time. Then when you get it out, it will be Tanzania time. Yay!
Now, the hairy question is: When I do an INSERT/UPDATE, how do I make sure the value is Tanzania time? Two cases:
You do INSERT INTO table (dateCreated) VALUES (CURRENT_TIMESTAMP or NOW())
.
You do INSERT INTO table (dateCreated) VALUES (?)
, and specify the current time from your application code.
CASE #1
MySQL will take the current time, let's say that is '2019-01-01 20:00:00' Tanzania time. Then MySQL will convert it to UTC, which comes out to '2019-01-01 17:00:00', and store that value into the field.
So how do you get the Tanzania time, which is '20:00:00', to store into the field? It's not possible. Your code will need to expect UTC time when reading from this field.
CASE #2
It depends on what type of value you pass as ?
. If you pass the string '2019-01-01 20:00:00', then good for you, that's exactly what will be stored to the DB. If you pass a Date object of some kind, then it'll depend on how the db driver interprets that Date object, and ultimate what 'YYYY-MM-DD HH:mm:ss' string it provides to MySQL for storage. The db driver's documentation should tell you.

I know I'm late on this (it's been two years since the question was asked) but I accomplished this by intercepting the back button press. Rather than checking for specific activities, I just look at the count and if it's less than 3 it simply sends the app to the back (pausing the app and returning the user to whatever was running before launch). I check for less than three because I only have one intro screen. Also, I check the count because my app allows the user to navigate back to the home screen through the menu, so this allows them to back up through other screens like normal if there are activities other than the intro screen on the stack.
//We want the home screen to behave like the bottom of the activity stack so we do not return to the initial screen
//unless the application has been killed. Users can toggle the session mode with a menu item at all other times.
@Override
public void onBackPressed() {
//Check the activity stack and see if it's more than two deep (initial screen and home screen)
//If it's more than two deep, then let the app proccess the press
ActivityManager am = (ActivityManager)this.getSystemService(Activity.ACTIVITY_SERVICE);
List<RunningTaskInfo> tasks = am.getRunningTasks(3); //3 because we have to give it something. This is an arbitrary number
int activityCount = tasks.get(0).numActivities;
if (activityCount < 3)
{
moveTaskToBack(true);
}
else
{
super.onBackPressed();
}
}
I had the same problem with a client of my company, the problem was that the driver sqljdbc4.jar, tries a convertion of character between the database and the driver. Each time that it did a request to the database, now you can imagine 650 connections concurrently, this did my sistem very very slow, for avoid this situation i add at the String of connection the following parameter:
SendStringParametersAsUnicode=false, then te connection must be something like url="jdbc:sqlserver://IP:PORT;DatabaseName=DBNAME;SendStringParametersAsUnicode=false"
After that, the system is very very fast, as the users are very happy with the change, i hope my input be of same.
Check if there's a .dockerignore
file, if so, add:
!mydir/test.json
!mydir/test.py
You can also do it at run time as follows :
HomePage.WindowState = WindowState.Maximized;
Something like:
$(".head h3").html("Public offers");
you are looking for PHP’s empty()

It seems that, according to the HTML5 spec, the value property of the textarea element should return '\r\n' for a newline:
The element's value is defined to be the element's raw value with the following transformation applied:
Replace every occurrence of a "CR" (U+000D) character not followed by a "LF" (U+000A) character, and every occurrence of a "LF" (U+000A) character not preceded by a "CR" (U+000D) character, by a two-character string consisting of a U+000D CARRIAGE RETURN "CRLF" (U+000A) character pair.
Following the link to 'value' makes it clear that it refers to the value property accessed in javascript:
Form controls have a value and a checkedness. (The latter is only used by input elements.) These are used to describe how the user interacts with the control.
However, in all five major browsers (using Windows, 11/27/2015), if '\r\n' is written to a textarea, the '\r' is stripped. (To test: var e=document.createElement('textarea'); e.value='\r\n'; alert(e.value=='\n');) This is true of IE since v9. Before that, IE was returning '\r\n' and converting both '\r' and '\n' to '\r\n' (which is the HTML5 spec). So... I'm confused.
To be safe, it's usually enough to use '\r?\n' in regular expressions instead of just '\n', but if the newline sequence must be known, a test like the above can be performed in the app.
You probably updated your Ubuntu installation and one of the updates included the upgrade of Apache to version 2.4.x
In Apache 2.4.x the vhost configuration files, located in the /etc/apache2/sites-available directory, must have the .conf extension.
Using terminal (mv command), rename all your existing configuration files and add the .conf extension to all of them.
mv /etc/apache2/sites-available/cmsplus.dev /etc/apache2/sites-available/cmsplus.dev.conf
If you get a "Permission denied" error, then add "sudo " in front of your terminal commands.
You do not need to make any other changes to the configuration files.
Enable the vhost(s):
a2ensite cmsplus.dev.conf
And then reload Apache:
service apache2 reload
Your sites should be up and running now.
UPDATE: As mentioned here, a Linux distribution that you installed changed the configuration to Include *.conf only. Therefore it has nothing to do with Apache 2.2 or 2.4

Simplest C/C++ any compiler/standard compliant solution, was mentioned by @leftaroundabout in comments above:
int x = *(int*)"abcd";
Or a bit more specific:
int x = *(int32_t*)"abcd";
One more solution, also compliant with C/C++ compiler/standard since C99 (except clang++, which has a known bug):
int x = ((union {char s[5]; int number;}){"abcd"}).number;
/* just a demo check: */
printf("x=%d stored %s byte first\n", x, x==0x61626364 ? "MSB":"LSB");
Here anonymous union is used to give a nice symbol-name to the desired numeric result, "abcd" string is used to initialize the lvalue of compound literal (C99).
In comprehension, the nested lists iteration should follow the same order than the equivalent imbricated for loops.
To understand, we will take a simple example from NLP. You want to create a list of all words from a list of sentences where each sentence is a list of words.
>>> list_of_sentences = [['The','cat','chases', 'the', 'mouse','.'],['The','dog','barks','.']]
>>> all_words = [word for sentence in list_of_sentences for word in sentence]
>>> all_words
['The', 'cat', 'chases', 'the', 'mouse', '.', 'The', 'dog', 'barks', '.']
To remove the repeated words, you can use a set {} instead of a list []
>>> all_unique_words = list({word for sentence in list_of_sentences for word in sentence}]
>>> all_unique_words
['.', 'dog', 'the', 'chase', 'barks', 'mouse', 'The', 'cat']
or apply list(set(all_words))
>>> all_unique_words = list(set(all_words))
['.', 'dog', 'the', 'chases', 'barks', 'mouse', 'The', 'cat']
I had a similar problem, not exactly the same conditions and then i saw this post. Hope it helps someone. Apparently i was using one of my EF entity models a base class for a type that was not specified as a db set in my dbcontext. To fix this issue i had to create a base class that had all the properties common to the two types and inherit from the new base class among the two types.
Example:
//Bad Flow
//class defined in dbcontext as a dbset
public class Customer{
public int Id {get; set;}
public string Name {get; set;}
}
//class not defined in dbcontext as a dbset
public class DuplicateCustomer:Customer{
public object DuplicateId {get; set;}
}
//Good/Correct flow*
//Common base class
public class CustomerBase{
public int Id {get; set;}
public string Name {get; set;}
}
//entity model referenced in dbcontext as a dbset
public class Customer: CustomerBase{
}
//entity model not referenced in dbcontext as a dbset
public class DuplicateCustomer:CustomerBase{
public object DuplicateId {get; set;}
}
When you use DateTime you are able to store a date and a time inside a variable.
The date can be a local time or a UTC time, it depend on you.
For example, I'm in Italy (+2 UTC)
var dt1 = new DateTime(2011, 6, 27, 12, 0, 0); // store 2011-06-27 12:00:00
var dt2 = dt1.ToUniversalTime() // store 2011-06-27 10:00:00
So, what happen when I print dt1 and dt2 including the timezone?
dt1.ToString("MM/dd/yyyy hh:mm:ss z")
// Compiler alert...
// Output: 06/27/2011 12:00:00 +2
dt2.ToString("MM/dd/yyyy hh:mm:ss z")
// Compiler alert...
// Output: 06/27/2011 10:00:00 +2
dt1 and dt2 contain only a date and a time information. dt1 and dt2 don't contain the timezone offset.
So where the "+2" come from if it's not contained in the dt1 and dt2 variable?
It come from your machine clock setting.
The compiler is telling you that when you use the 'zzz' format you are writing a string that combine "DATE + TIME" (that are store in dt1 and dt2) + "TIMEZONE OFFSET" (that is not contained in dt1 and dt2 because they are DateTyme type) and it will use the offset of the server machine that it's executing the code.
The compiler tell you "Warning: the output of your code is dependent on the machine clock offset"
If i run this code on a server that is positioned in London (+1 UTC) the result will be completly different: instead of "+2" it will write "+1"
...
dt1.ToString("MM/dd/yyyy hh:mm:ss z")
// Output: 06/27/2011 12:00:00 +1
dt2.ToString("MM/dd/yyyy hh:mm:ss z")
// Output: 06/27/2011 10:00:00 +1
The right solution is to use DateTimeOffset data type in place of DateTime. It's available in sql Server starting from the 2008 version and in the .Net framework starting from the 3.5 version
Use substring to get everything to the left of _bar. But first you have to get the instr of _bar in the string:
str.substring(3, 7);
3 is that start and 7 is the length.
I always use a utility function/class for reading from the $_GET and $_POST arrays to avoid having to always check the index exists... Something like this will do the trick.
class Input {
function get($name) {
return isset($_GET[$name]) ? $_GET[$name] : null;
}
function post($name) {
return isset($_POST[$name]) ? $_POST[$name] : null;
}
function get_post($name) {
return $this->get($name) ? $this->get($name) : $this->post($name);
}
}
$input = new Input;
$page = $input->get_post('page');
You won't be able to make an ajax call to http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml
from a file deployed at http://run.jsbin.com
due to the same-origin policy.
As the source (aka origin) page and the target URL are at different domains (run.jsbin.com
and www.ecb.europa.eu
), your code is actually attempting to make a Cross-domain (CORS) request, not an ordinary GET
.
In a few words, the same-origin policy says that browsers should only allow ajax calls to services at the same domain of the HTML page.
A page at http://www.example.com/myPage.html
can only directly request services that are at http://www.example.com
, like http://www.example.com/api/myService
. If the service is hosted at another domain (say http://www.ok.com/api/myService
), the browser won't make the call directly (as you'd expect). Instead, it will try to make a CORS request.
To put it shortly, to perform a (CORS) request* across different domains, your browser:
Origin
header in the original request (with the page's domain as value) and perform it as usual; and thenAccess-Control-Allow-Origin
is one of them) allowing the CORS request, the browse will complete the call (almost** exactly the way it would if the HTML page was at the same domain).
* The above depicts the steps in a simple request, such as a regular GET
with no fancy headers. If the request is not simple (like a POST
with application/json
as content type), the browser will hold it a moment, and, before fulfilling it, will first send an OPTIONS
request to the target URL. Like above, it only will continue if the response to this OPTIONS
request contains the CORS headers. This OPTIONS
call is known as preflight request.
** I'm saying almost because there are other differences between regular calls and CORS calls. An important one is that some headers, even if present in the response, will not be picked up by the browser if they aren't included in the Access-Control-Expose-Headers
header.
Was it just a typo? Sometimes the JavaScript code has just a typo in the target domain. Have you checked? If the page is at www.example.com
it will only make regular calls to www.example.com
! Other URLs, such as api.example.com
or even example.com
or www.example.com:8080
are considered different domains by the browser! Yes, if the port is different, then it is a different domain!
Add the headers. The simplest way to enable CORS is by adding the necessary headers (as Access-Control-Allow-Origin
) to the server's responses. (Each server/language has a way to do that - check some solutions here.)
Last resort: If you don't have server-side access to the service, you can also mirror it (through tools such as reverse proxies), and include all the necessary headers there.

In software engineering, multi-tier architecture (often referred to as n-tier architecture) is a client-server architecture in which, the presentation, the application processing and the data management are logically separate processes. For example, an application that uses middleware to service data requests between a user and a database employs multi-tier architecture. The most widespread use of "multi-tier architecture" refers to three-tier architecture.
It's debatable what counts as "tiers," but in my opinion it needs to at least cross the process boundary. Or else it's called layers. But, it does not need to be in physically different machines. Although I don't recommend it, you can host logical tier and database on the same box.
Edit: One implication is that presentation tier and the logic tier (sometimes called Business Logic Layer) needs to cross machine boundaries "across the wire" sometimes over unreliable, slow, and/or insecure network. This is very different from simple Desktop application where the data lives on the same machine as files or Web Application where you can hit the database directly.
For n-tier programming, you need to package up the data in some sort of transportable form called "dataset" and fly them over the wire. .NET's DataSet class or Web Services protocol like SOAP are few of such attempts to fly objects over the wire.

It is probably easiest just to exhibit the difference. Consider the tree:
A
/ \
B C
/ / \
D E F
A depth first traversal would visit the nodes in this order
A, B, D, C, E, F
Notice that you go all the way down one leg before moving on.
A breadth first traversal would visit the node in this order
A, B, C, D, E, F
Here we work all the way across each level before going down.
(Note that there is some ambiguity in the traversal orders, and I've cheated to maintain the "reading" order at each level of the tree. In either case I could get to B before or after C, and likewise I could get to E before or after F. This may or may not matter, depends on you application...)
Both kinds of traversal can be achieved with the pseudocode:
Store the root node in Container
While (there are nodes in Container)
N = Get the "next" node from Container
Store all the children of N in Container
Do some work on N
The difference between the two traversal orders lies in the choice of Container
.
The recursive implementation looks like
ProcessNode(Node)
Work on the payload Node
Foreach child of Node
ProcessNode(child)
/* Alternate time to work on the payload Node (see below) */
The recursion ends when you reach a node that has no children, so it is guaranteed to end for finite, acyclic graphs.
At this point, I've still cheated a little. With a little cleverness you can also work-on the nodes in this order:
D, B, E, F, C, A
which is a variation of depth-first, where I don't do the work at each node until I'm walking back up the tree. I have however visited the higher nodes on the way down to find their children.
This traversal is fairly natural in the recursive implementation (use the "Alternate time" line above instead of the first "Work" line), and not too hard if you use a explicit stack, but I'll leave it as an exercise.
replace:true
is DeprecatedFrom the Docs:
replace
([DEPRECATED!], will be removed in next major release - i.e. v2.0)specify what the template should replace. Defaults to
false
.
true
- the template will replace the directive's element.false
- the template will replace the contents of the directive's element.
-- AngularJS Comprehensive Directive API
From GitHub:
Caitp-- It's deprecated because there are known, very silly problems with
replace: true
, a number of which can't really be fixed in a reasonable fashion. If you're careful and avoid these problems, then more power to you, but for the benefit of new users, it's easier to just tell them "this will give you a headache, don't do it".
Note:
replace: true
is deprecated and not recommended to use, mainly due to the issues listed here. It has been completely removed in the new Angular.
transclude: element
in the replace template root can have unexpected effectsFor more information, see
I like the answer that attempts to do the translate, however, while using the code it doesn't like columns that are not VARCHAR type such as BIGINT or DATETIME. I needed something similar today so I took the time to modify it more to my liking. It is also now encapsulated in a function which is the closest thing I could find to just typing describe as oracle handles it. I may still be missing a few data types in my case statement but this works for everything I tried it on. It also orders by ordinal position. this could be expanded on to include primary key columns easily as well.
CREATE FUNCTION dbo.describe (@TABLENAME varchar(50))
returns table
as
RETURN
(
SELECT TOP 1000 column_name AS [ColumnName],
IS_NULLABLE AS [IsNullable],
DATA_TYPE + '(' + CASE
WHEN DATA_TYPE = 'varchar' or DATA_TYPE = 'char' THEN
CASE
WHEN Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5)) = -1 THEN 'Max'
ELSE Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5))
END
WHEN DATA_TYPE = 'decimal' or DATA_TYPE = 'numeric' THEN
Cast(NUMERIC_PRECISION AS VARCHAR(5))+', '+Cast(NUMERIC_SCALE AS VARCHAR(5))
WHEN DATA_TYPE = 'bigint' or DATA_TYPE = 'int' THEN
Cast(NUMERIC_PRECISION AS VARCHAR(5))
ELSE ''
END + ')' AS [DataType]
FROM INFORMATION_SCHEMA.Columns
WHERE table_name = @TABLENAME
order by ordinal_Position
);
GO
once you create the function here is a sample table that I used
create table dbo.yourtable
(columna bigint,
columnb int,
columnc datetime,
columnd varchar(100),
columne char(10),
columnf bit,
columng numeric(10,2),
columnh decimal(10,2)
)
Then you can execute it as follows
select * from describe ('yourtable')
It returns the following
ColumnName IsNullable DataType
columna NO bigint(19)
columnb NO int(10)
columnc NO datetime()
columnd NO varchar(100)
columne NO char(10)
columnf NO bit()
columng NO numeric(10, 2)
columnh NO decimal(10, 2)
hope this helps someone.
I think in certain cases, you can create a FAKE "list" of items in the database, for example, the merchandise has a few pictures to show its details, you can concatenate all the IDs of pictures split by comma and store the string into the DB, then you just need to parse the string when you need it. I am working on a website now and I am planning to use this way.

In a couple of words, this query:
SELECT d1.short_code
FROM domain1 d1
LEFT JOIN
domain2 d2
ON d2.short_code = d1.short_code
WHERE d2.short_code IS NULL
will work but it is less efficient than a NOT NULL
(or NOT EXISTS
) construct.
You can also use this:
SELECT short_code
FROM domain1
EXCEPT
SELECT short_code
FROM domain2
This is using neither NOT IN
nor WHERE
(and even no joins!), but this will remove all duplicates on domain1.short_code
if any.
You are running Python 2, not Python 3. For this to work in Python 2, use raw_input
.
input_variable = raw_input ("Enter your name: ")
print ("your name is" + input_variable)
Supplemental answer with Swift code
Quartz 2D graphics use a coordinate system with the origin in the bottom left while UIKit in iOS uses a coordinate system with the origin at the top left. Everything usually works fine but when doing some graphics operations, you have to modify the coordinate system yourself. The documentation states:
Some technologies set up their graphics contexts using a different default coordinate system than the one used by Quartz. Relative to Quartz, such a coordinate system is a modified coordinate system and must be compensated for when performing some Quartz drawing operations. The most common modified coordinate system places the origin in the upper-left corner of the context and changes the y-axis to point towards the bottom of the page.
This phenomenon can be seen in the following two instances of custom views that draw an image in their drawRect
methods.
On the left side, the image is upside-down and on the right side the coordinate system has been translated and scaled so that the origin is in the top left.
Upside-down image
override func drawRect(rect: CGRect) {
// image
let image = UIImage(named: "rocket")!
let imageRect = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)
// context
let context = UIGraphicsGetCurrentContext()
// draw image in context
CGContextDrawImage(context, imageRect, image.CGImage)
}
Modified coordinate system
override func drawRect(rect: CGRect) {
// image
let image = UIImage(named: "rocket")!
let imageRect = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)
// context
let context = UIGraphicsGetCurrentContext()
// save the context so that it can be undone later
CGContextSaveGState(context)
// put the origin of the coordinate system at the top left
CGContextTranslateCTM(context, 0, image.size.height)
CGContextScaleCTM(context, 1.0, -1.0)
// draw the image in the context
CGContextDrawImage(context, imageRect, image.CGImage)
// undo changes to the context
CGContextRestoreGState(context)
}
This is a risk to turning off this option. You can lose changes if you have change tracking turned on (your tables).

I created a small class to grab data from the provided url, then extract html elements of your choice. The class makes use of CURL and DOMDocument.
php class:
class crawler {
public static $timeout = 2;
public static $agent = 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)';
public static function http_request($url) {

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, self::$agent);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, self::$timeout);
curl_setopt($ch, CURLOPT_TIMEOUT, self::$timeout);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
public static function strip_whitespace($data) {
$data = preg_replace('/\s+/', ' ', $data);
return trim($data);
}
public static function extract_elements($tag, $data) {
$response = array();
$dom = new DOMDocument;
@$dom->loadHTML($data);
foreach ( $dom->getElementsByTagName($tag) as $index => $element ) {
$response[$index]['text'] = self::strip_whitespace($element->nodeValue);
foreach ( $element->attributes as $attribute ) {
$response[$index]['attributes'][strtolower($attribute->nodeName)] = self::strip_whitespace($attribute->nodeValue);
}
}
return $response;
}
}
example usage:
$data = crawler::http_request('https://stackoverflow.com/questions/2313107/how-do-i-make-a-simple-crawler-in-php');
$links = crawler::extract_elements('a', $data);
if ( count($links) > 0 ) {

Try with below code.
Like GridView in LinkButton, Label, HtmlAnchor and HtmlInputControl.
<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
OnRowDataBound="mainGrid_RowDataBound" EmptyDataText="No Data Found.">
<Columns>
<asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
<asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
<a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
<input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Handling RowDataBound event,
protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblName = (Label)e.Row.FindControl("lblName");
LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
}
}
The easiest solution would be in CSS. Add something like...
.dropdown:hover .dropdown-menu {
display: block;
margin-top: 0; // remove the gap so it doesn't close
}
The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date')
declare the date property like so: private _date: string;
. Also, make sure you are instantiating the model with the new
keyword. Lastly, access the property using regular dot notation.
Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :
let passcode = "secret passcode";
class Employee {
private _fullName: string;
get fullName(): string {
return this._fullName;
}
set fullName(newName: string) {
if (passcode && passcode == "secret passcode") {
this._fullName = newName;
}
else {
console.log("Error: Unauthorized update of employee!");
}
}
}
let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
console.log(employee.fullName);
}
And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview
You can use the Bean Comparator to sort on any property in your custom class.
I just fixed this problem (Different Case with same error),
The answer above I tried may not work because My case were different but produced the same error.
I think my vendor libraries were jumbled,
I get this error by:
1. Pull from remote git, master branch is codeigniter then I do composer update on master branch, I wanted to work on laravel branch then I checkout and do composer update so I get the error,
Fatal error: Class 'Illuminate\Foundation\Application' not found in C:\cms\bootstrap\app.php on line 14
Solution: I delete the project on local and do a clone again, after that I checkout to my laravel file work's branch and do composer update then it is fixed.
There's no catchall function, because there are multiple concerns to be addressed.
SQL Injection - Today, generally, every PHP project should be using prepared statements via PHP Data Objects (PDO) as a best practice, preventing an error from a stray quote as well as a full-featured solution against injection. It's also the most flexible & secure way to access your database.
Check out (The only proper) PDO tutorial for pretty much everything you need to know about PDO. (Sincere thanks to top SO contributor, @YourCommonSense, for this great resource on the subject.)
XSS - Sanitize data on the way in...
HTML Purifier has been around a long time and is still actively updated. You can use it to sanitize malicious input, while still allowing a generous & configurable whitelist of tags. Works great with many WYSIWYG editors, but it might be heavy for some use cases.
In other instances, where we don't want to accept HTML/Javascript at all, I've found this simple function useful (and has passed multiple audits against XSS):
/* Prevent XSS input */
function sanitizeXSS () {
$_GET = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING);
$_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);
$_REQUEST = (array)$_POST + (array)$_GET + (array)$_REQUEST;
}
XSS - Sanitize data on the way out... unless you guarantee the data was properly sanitized before you add it to your database, you'll need to sanitize it before displaying it to your user, we can leverage these useful PHP functions:
echo
or print
to display user-supplied values, use htmlspecialchars
unless the data was properly sanitized safe and is allowed to display HTML.json_encode
is a safe way to provide user-supplied values from PHP to JavascriptDo you call external shell commands using exec()
or system()
functions, or to the backtick
operator? If so, in addition to SQL Injection & XSS you might have an additional concern to address, users running malicious commands on your server. You need to use escapeshellcmd
if you'd like to escape the entire command OR escapeshellarg
to escape individual arguments.
You can add image to asp.net button. you dont need to use only image button or link button. When displaying button on browser, it is converting to html button as default. So you can use its "Style" properties for adding image. My example is below. I hope it works for you.
Style="background-image:url('Image/1.png');"
You can change image location with using
background-repeat
properties. So you can write a button like below:
<asp:Button ID="btnLogin" runat="server" Text="Login" Style="background-image:url('Image/1.png'); background-repeat:no-repeat"/>
Using prepared statements, there is no "SQL query" :
But there is no re-construction of an actual real SQL query -- neither on the Java side, nor on the database side.
So, there is no way to get the prepared statement's SQL -- as there is no such SQL.
For debugging purpose, the solutions are either to :
For those who didn't know what next, just add new module file and put @jor code (with my little hacked, supporting 'nothing' array) below.
Module ArrayExtension
<Extension()> _
Public Sub Add(Of T)(ByRef arr As T(), item As T)
If arr IsNot Nothing Then
Array.Resize(arr, arr.Length + 1)
arr(arr.Length - 1) = item
Else
ReDim arr(0)
arr(0) = item
End If
End Sub
End Module

To add the stdout and stderr to the general logfile of a script:

SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.
I'd think about using a library like momentjs.com, that makes this really simple:
Based on a Unix timestamp:
var timestamp = moment.unix(1293683278);
console.log( timestamp.format("HH/mm/ss") );
Based on a MySQL date string:
var now = moment("2010-10-10 12:03:15");
console.log( now.format("HH/mm/ss") );
Use another cable.
Just found out that one of my regular charging cables had Vcc, Gnd pairs, but no Data+, Data-.
Just as reference, you can also use Mysql Variables to save temporary results, e.g.:
SET @v1 := (SELECT ... );
UPDATE ... SET ... WHERE x=@v1;
Here complete code for date picker with date format (yy/mm/dd).
Copy link below and paste in head tag :
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script type="text/javascript">
$(function() {
$("#datepicker").datepicker({ dateFormat: "yy-mm-dd" }).val()
});
</script>
Copy below code and paste between body tag :
Date: <input type="text" id="datepicker" size="30"/>
If you would like two(2) input type text like Start Date
and End Date
then use this script and change date format.
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>

<script type="text/javascript">
$(function() {
$("#startdate").datepicker({ dateFormat: "dd-mm-yy" }).val()
$("#enddate").datepicker({ dateFormat: "dd-mm-yy" }).val()
});
</script>
Two input text like :
Start Date: <input type="text" id="startdate" size="30"/>
End Date: <input type="text" id="enddate" size="30"/>
In Java, the default initialization is applicable for only instance variable of class member.
It isn't applicable for local variables.
You may use this:
Intent intent = new Intent(getApplicationContext(), ClassName.class);
Maybe because you have a tag like a parent of the tag. That why you have to click two time the images.
For me the solution is this: http://www.w3schools.com/js/tryit.asp?filename=tryjs_intro_lightbulb

I recommend Google protocol buffers. I had the chance to test drive the library on a new project and it's remarkably easy to use. The library is heavily optimized for performance.
Protobuf is different than other serialization solutions mentioned here in the sense that it does not serialize your objects, but rather generates code for objects that are serialization according to your specification.
This came up in a search I was just doing, found a better solution with some more searching, IPython notebooks now have a %%latex

The C++20 draft contains the convenience function std::erase_if
.
So you can use that function to do it as a one-liner.
std::map<K, V> map_obj;
//calls needs_removing for each element and erases it, if true was reuturned
std::erase_if(map_obj,needs_removing);
//if you need to pass only part of the key/value pair
std::erase_if(map_obj,[](auto& kv){return needs_removing(kv.first);});
You used to be able to do this, but GitHub removed this feature at some point mid-2013. To achieve this locally, you can do:
git log -g --grep=STRING
(Use the -g
flag if you want to search other branches and dangling commits.)
-g, --walk-reflogs
Instead of walking the commit ancestry chain, walk reflog entries from
the most recent one to older ones.
I agree with Christian Muggli's solution, although at first I still got the error that Scott Weinstein reported. How you get past that is:
EITHER first login to Gmail from the machine this will run on, using the account specified. (It is not necessary to add any Google sites to the Trusted Sites zone, even if Internet Explorer Enhanced Security Configuration is enabled.)
OR, on your first attempt, you will get the error, and your Gmail account will get a notice about suspicious login, so follow their instructions to allow future logins from the machine this will run on.
NOLOCK makes most SELECT statements faster, because of the lack of shared locks. Also, the lack of issuance of the locks means that writers will not be impeded by your SELECT.
NOLOCK is functionally equivalent to an isolation level of READ UNCOMMITTED. The main difference is that you can use NOLOCK on some tables but not others, if you choose. If you plan to use NOLOCK on all tables in a complex query, then using SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED is easier, because you don't have to apply the hint to every table.
Here is information about all of the isolation levels at your disposal, as well as table hints.

You are looking for serialize(). Here is an example:
$array = array('foo', 'bar');
//Array to String
$string = serialize($array);
//String to array
$array = unserialize($string);

2> Same method but diff params, still jvm calling "main(String[] args) " meyhod.
3> Exactly same method but it gives copile time error as you can not have two same name method in a single class !!!

Try this, it will worked. I used it for Hashtable.
public static Hashtable<Integer, KioskStatusResource> parseModifued(String json) {
JsonObject object = (JsonObject) new com.google.gson.JsonParser().parse(json);
Set<Map.Entry<String, JsonElement>> set = object.entrySet();
Iterator<Map.Entry<String, JsonElement>> iterator = set.iterator();
Hashtable<Integer, KioskStatusResource> map = new Hashtable<Integer, KioskStatusResource>();
while (iterator.hasNext()) {
Map.Entry<String, JsonElement> entry = iterator.next();
Integer key = Integer.parseInt(entry.getKey());
KioskStatusResource value = new Gson().fromJson(entry.getValue(), KioskStatusResource.class);
if (value != null) {
map.put(key, value);
}
}
return map;
}
Replace KioskStatusResource to your class and Integer to your key class.
Assume drawTriangle is an instance of UIView.To check whether drawTriangle is of type UITableView:
In Swift 3,
if drawTriangle is UITableView{
// in deed drawTriangle is UIView
// do something here...
} else{
// do something here...
}
This also could be used for classes defined by yourself. You could use this to check subviews of a view.
Simply add height: 100%;
onto the #B2
styling. min-height
shouldn't be necessary.
I use the following
void split(string in, vector<string>& parts, char separator) {
string::iterator ts, curr;
ts = curr = in.begin();
for(; curr <= in.end(); curr++ ) {
if( (curr == in.end() || *curr == separator) && curr > ts )
parts.push_back( string( ts, curr ));
if( curr == in.end() )
break;
if( *curr == separator ) ts = curr + 1;
}
}
PlasmaHH, I forgot to include the extra check( curr > ts) for removing tokens with whitespace.
