You need to update the output of json.load with a_dict and then dump the result. And you cannot append to the file but you need to overwrite it.
I can't replicate that (php 5.3.6):
php > $error = array();
php > $error['something'] = false;
php > $error['somethingelse'] = false;
php > var_dump(empty($error));
bool(false)
php > $error = array();
php > var_dump(empty($error));
bool(true)
php >
exactly where are you doing the empty()
call that returns true?
If it's inside a closure, i'm pretty sure you can't.
Otherwise you just do functionName();
and hit return.
As we have well established here, writelines
does not append the newlines for you. But, what everyone seems to be missing, is that it doesn't have to when used as a direct "counterpart" for readlines()
and the initial read persevered the newlines!
When you open a file for reading in binary mode (via 'rb'
), then use readlines()
to fetch the file contents into memory, split by line, the newlines remain attached to the end of your lines! So, if you then subsequently write them back, you don't likely want writelines
to append anything!
So if, you do something like:
with open('test.txt','rb') as f: lines=f.readlines()
with open('test.txt','wb') as f: f.writelines(lines)
You should end up with the same file content you started with.
it is completely transparent Edittext with transparent background.

RABL is probably the nicest solution to this that I've seen if you're looking for a cleaner alternative to ERb syntax. json_builder and argonaut, which are other solutions, both seem somewhat outdated and won't work with Rails 3.1 without some patching.
RABL is available via a gem or check out the GitHub repository; good examples too
There is a bunch on here:
http://www.webservicex.net/WS/wscatlist.aspx
Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.
Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.
It happens when sometimes we copy or import the project from somewhere. The source folder is a big thing to concern about.
One simple technique is, create a new project, inside the source folder, create a new class and paste the content over there.
It will work...
Hope it helps.
The default class constructor is called unless you explicitly call another constructor in the derived class. the language specifies this.
Rectangle(int h,int w):
Shape(h,w)
{...}
Will call the other base class constructor.
Stop MySQL using the following command:
sudo /etc/init.d/mysql stop
Copy the existing data directory (default located in /var/lib/mysql
) using the following command:
sudo cp -R -p /var/lib/mysql /newpath
edit the MySQL configuration file with the following command:
sudo gedit /etc/mysql/my.cnf # or perhaps /etc/mysql/mysql.conf.d/mysqld.cnf
Look for the entry for datadir
, and change the path (which should be /var/lib/mysql
) to the new data directory.
In the terminal, enter the command:
sudo gedit /etc/apparmor.d/usr.sbin.mysqld
Look for lines beginning with /var/lib/mysql
. Change /var/lib/mysql
in the lines with the new path.
Save and close the file.
Restart the AppArmor profiles with the command:
sudo /etc/init.d/apparmor reload
Restart MySQL with the command:
sudo /etc/init.d/mysql restart
Now login to MySQL and you can access the same databases you had before.
You can use JQuery, select the item by id:
$("input#Password").attr("autocomplete","off");
Or select the item by type:
$("input[type='password']").attr("autocomplete","off");
Or also:
You can use pure Javascript:
document.getElementById('Password').autocomplete = 'off';
This can be used in to solve this problem
<div id='scrol'></div>
in javascript use this
jQuery("div#scrol").scrollTop(jQuery("div#scrol")[0].scrollHeight);
Git just stores the contents of the link (i.e. the path of the file system object that it links to) in a 'blob' just like it would for a normal file. It then stores the name, mode and type (including the fact that it is a symlink) in the tree object that represents its containing directory.
When you checkout a tree containing the link, it restores the object as a symlink regardless of whether the target file system object exists or not.
If you delete the file that the symlink references it doesn't affect the Git-controlled symlink in any way. You will have a dangling reference. It is up to the user to either remove or change the link to point to something valid if needed.
You are probably missing gradle-wrapper.jar
file under directory gradle/wrapper
in your project.
You need to generate this file via this script in build.gradle file as below,
task wrapper(type: Wrapper) {
gradleVersion = '2.0' // version required
}
and run task:
gradle wrapper
With gradle 2.4 (or higher) you can set up a wrapper without adding a dedicated task:
gradle wrapper --gradle-version 2.3
OR
gradle wrapper --gradle-distribution-url https://myEnterpriseRepository:7070/gradle/distributions/gradle-2.3-bin.zip

It seems like that it is only me who are so clumsy, because i have yet to found a solution that my case required.
I am developing a multi-modular project, thus base android module configuration is extracted in single gradle script. All the concrete versions of sdks/libs are also extracted in a script.
A script containing versions looked like this:
...
ext.androidVersions = [
compile_sdk_version : '27',
min_sdk_version : '19',
target_sdk_version : '27',
build_tool_version : '27.0.3',
application_id : 'com.test.test',
]
...
Not accustomed to groovy syntax my eye has not spotted that the values for compile, min and target sdks were not integers but STRINGS! Therefore a compiler rightfully complained about not being able to find an sdk a version of which would match HASH STRING '27'.
So the solution would be to make sdk's versions integers: ...
ext.androidVersions = [
compile_sdk_version : 27,
min_sdk_version : 19,
target_sdk_version : 27,
build_tool_version : '27.0.3',
application_id : 'com.test.test',
]
...
While a set
may be what you want structure-wise, the question is what is faster. A list is faster. Your example code doesn't accurately compare set
vs list
because you're converting from a list to a set in set_loop
, and then you're creating the list
you'll be looping through in list_loop
. The set and list you iterate through should be constructed and in memory ahead of time, and simply looped through to see which data structure is faster at iterating:
ids_list = range(1000000)
ids_set = set(ids)
def f(x):
for i in x:
pass
%timeit f(ids_set)
#1 loops, best of 3: 214 ms per loop
%timeit f(ids_list)
#1 loops, best of 3: 176 ms per loop
One option if the number of keys is small is to use chained gets:
value = myDict.get('lastName', myDict.get('firstName', myDict.get('userName')))
But if you have keySet defined, this might be clearer:
value = None
for key in keySet:
if key in myDict:
value = myDict[key]
break
The chained get
s do not short-circuit, so all keys will be checked but only one used. If you have enough possible keys that that matters, use the for
loop.
Note for the answer-seekers (who I also was) - if using arc is not obligatory, a far simpler solution to draw a part-circle is to use stroke-dasharray
of SVG <circle>
.
Divide dash array into two elements, and scale their range to the desired angle. Starting angle can be adjusted using stroke-dashoffset
.
Not a single cosine in sight.

You can try this: In my case i am loading menu from database based on role based access, Write the code on your every view which menu your want to active based on your view.
<script type="text/javascript">
$(document).ready(function () {
$('li.active active-menu').removeClass('active active-menu');
$('a[href="/MgtCustomer/Index"]').closest('li').addClass('active active-menu');
});
</script>
As mentioned several times above, 'self' is simply being used to keep a reference to 'this' prior to entering the funcition. Once in the function 'this' refers to something else.
Using Jquery, simply use this function:
<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
}
</script>
Your print button will look like this:
<button id="print" onclick="printContent('id name of your div');" >Print</button>
Edit: If you DO have form data that you need to keep, clone won't copy that, so you'll just need to grab all the form data and replace it after restore as so:
<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
var enteredtext = $('#text').val();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
$('#text').html(enteredtext);
}
</script>
<textarea id="text"></textarea>
The bootstrap 4.0.0 file you are getting from cdn doesn't have a pull-right (or pull-left) class. The v4 is in alpha, so there are many issues like that.
There are 2 options:
1) Reverse to bootstrap 3.3.7
2) Write your own CSS.
I was importing also some projects from VS2010 to VS 2012. I had the same errors. The errors disappeared when I set back Properties > Config. Properties > General > Platform Toolset to v100 (VS2010). That might not be the correct approach, however.
Another good use for Dispatcher.Invoke
is for immediately updating the UI in a function that performs other tasks:
// Force WPF to render UI changes immediately with this magic line of code...
Dispatcher.Invoke(new Action(() => { }), DispatcherPriority.ContextIdle);
I use this to update button text to "Processing..." and disable it while making WebClient
requests.
Element.scrollHeight
is a property, not a function, as noted here. As noted here, the scrollHeight property is only supported after IE8. If you need it to work before that, temporarily set the CSS overflow
and height
to auto
, which will cause the div to take the maximum height it needs. Then get the height, and change the properties back to what they were before.
I found that AlertifyJS is a better alternative and have a Bootstrap theme.
alertify.alert('Alert Title', 'Alert Message!', function(){ alertify.success('Ok'); });
Also have a 4 components: Alert, Confirm, Prompt and Notifier.
Exmaple: JSFiddle
For anyone who lands here by searching:
content type 'application/json; charset=utf-8' was not the expected type 'text/xml; charset=utf-8
or some subset of that error:
A similar error was caused in my case by building and running a service without proper attributes. I got this error message when I tried to update the service reference in my client application. It was resolved when I correctly applied [DataContract]
and [DataMember]
attributes to my custom classes.
This would most likely be applicable if your service was set up and working and then it broke after you edited it.
it doesn't work that way. the work around is to manually check the coordinates of the mouse click against the area occupied by each element.
area occupied by an element can found found by 1. getting the location of the element with respect to the top left of the page, and 2. the width and the height. a library like jQuery makes this pretty simple, although it can be done in plain js. adding an event handler for mousemove
on the document
object will provide continuous updates of the mouse position from the top and left of the page. deciding if the mouse is over any given object consists of checking if the mouse position is between the left, right, top and bottom edges of an element.
Unexpected end of file
means that something else was expected before the PHP parser reached the end of the script.
Judging from your HUGE file, it's probably that you're missing a closing brace (}
) from an if
statement.
Please at least attempt the following things:
;
in some of your embedded PHP statements, and not in others, ie. <?php echo base_url(); ?>
vs <?php echo $this->layouts->print_includes() ?>
. It's not required, so don't use it (or do, just do one or the other).In ES6, import
s are live read-only views on exported-values. As a result, when you do import a from "somemodule";
, you cannot assign to a
no matter how you declare a
in the module.
However, since imported variables are live views, they do change according to the "raw" exported variable in exports. Consider the following code (borrowed from the reference article below):
//------ lib.js ------
export let counter = 3;
export function incCounter() {
counter++;
}
//------ main1.js ------
import { counter, incCounter } from './lib';
// The imported value `counter` is live
console.log(counter); // 3
incCounter();
console.log(counter); // 4
// The imported value can’t be changed
counter++; // TypeError
As you can see, the difference really lies in lib.js
, not main1.js
.
To summarize:
import
-ed variables, no matter how you declare the corresponding variables in the module.let
-vs-const
semantics applies to the declared variable in the module.
const
, it cannot be reassigned or rebound in anywhere.let
, it can only be reassigned in the module (but not the user). If it is changed, the import
-ed variable changes accordingly.Here's the generic method to get values from map.
public static <T> List<T> ValueListFromMap(HashMap<String, T> map) {
List<T> thingList = new ArrayList<>();
for (Map.Entry<String, T> entry : map.entrySet()) {
thingList.add(entry.getValue());
}
return thingList;
}
a simple way would be to cast the dates into timestamps and take their difference and then extract the DAY part.
if you want real difference
select extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp);
if you want absolute difference
select abs(extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp));
You can do the following:
echo '<div class="my_class">';
echo ($cart->count_product > 0) ? $cart->count_product : '';
echo '</div>';
If you want to have it inside your statement, do this:
if($cart->count_product > 0)
{
echo '<div class="my_class">'.$cart->count_product.'</div>';
}
You don't need the else
statement, since you're only going to output the above when it's truthy anyway.
Please first delete data from that table and then run the migration again. You will get success
Yes it's possible. Follow these steps:
Use git show $COMMIT
. It'll show you the log message for the commit, and the diff of that particular commit.
Try the change event and selected selector
$('#jobSel').change(function(){
var optId = $(this).find('option:selected').attr('id')
})
use rgba
(rgb with alpha transparency
):
border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity
The alpha transparency
variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)
let parameters = ["foo": "bar"]
// All three of these calls are equivalent
AF.request("https://httpbin.org/post", method: .post, parameters: parameters)

Swift 3 using appearance from your AppDelegate
do the following:
UITabBar.appearance().barTintColor = your_color
$(document).ready(function() {
$('#ckbCheckAll').click(function() {
$('.checkBoxClass').each(function() {
$(this).attr('checked',!$(this).attr('checked'));
});
});
});
OR
$(function () {
$('#ckbCheckAll').toggle(
function() {
$('.checkBoxClass').prop('checked', true);
},
function() {
$('.checkBoxClass').prop('checked', false);
}
);
});
Here is a fairly easy to understand version using method syntax:
IEnumerable<JoinPair> outerLeft =
lefts.SelectMany(l =>
rights.Where(r => l.Key == r.Key)
.DefaultIfEmpty(new Item())
.Select(r => new JoinPair { LeftId = l.Id, RightId = r.Id }));
You can use setTimeout()
and clearTimeout()
in conjunction with jQuery.data
:
$(window).resize(function() {
clearTimeout($.data(this, 'resizeTimer'));
$.data(this, 'resizeTimer', setTimeout(function() {
//do something
alert("Haven't resized in 200ms!");
}, 200));
});
Update
I wrote an extension to enhance jQuery's default on
(& bind
)-event-handler. It attaches an event handler function for one or more events to the selected elements if the event was not triggered for a given interval. This is useful if you want to fire a callback only after a delay, like the resize event, or else.
https://github.com/yckart/jquery.unevent.js
;(function ($) {
var methods = { on: $.fn.on, bind: $.fn.bind };
$.each(methods, function(k){
$.fn[k] = function () {
var args = [].slice.call(arguments),
delay = args.pop(),
fn = args.pop(),
timer;
args.push(function () {
var self = this,
arg = arguments;
clearTimeout(timer);
timer = setTimeout(function(){
fn.apply(self, [].slice.call(arg));
}, delay);
});
return methods[k].apply(this, isNaN(delay) ? arguments : args);
};
});
}(jQuery));
Use it like any other on
or bind
-event handler, except that you can pass an extra parameter as a last:
$(window).on('resize', function(e) {
console.log(e.type + '-event was 200ms not triggered');
}, 200);
The right place to download the JDK for Java 7 is Java SE Downloads.
All the other links provided above, as far as I can tell, either provide the JRE or Java 6 downloads (incidentally, if you want to run Eclipse or other IDEs, like IntelliJ IDEA, you will need the JDK, not the JRE).
Regarding IntelliJ IDEA - that will still ask you to install Java 6 as it apparently needs an older class loader or something: just follow the instructions when the dialog pop-up appears and it will install the JDK 6 in the right place.
Afterwards, you will need to do the sudo ln -snf
mentioned in the answer above:
sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents \
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK
(copied here as it was mentioned that "above" may eventually not make sense as answers are re-sorted).
I also set my JAVA_HOME
to point to where jdk_1.7.0_xx.jdk
was installed:
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home"
Then add that to your PATH
:
export PATH=$JAVA_HOME/bin:$PATH
The alternative is to fuzz around with Apple's insane maze of hyperlinks, but honestly life is too short to bother.
This thread is quite old, but you could also think about a recursive solution passing the StringBuilder to fill. This allows to prevent any reverse processing etc. Just need to design your iteration with a recursion and carefully decide for an exit condition.
public class Test {
public static void main(String[] args) {
StringBuilder sb = new StringBuilder();
doRecursive(sb, 100, 0);
System.out.println(sb.toString());
}
public static void doRecursive(StringBuilder sb, int limit, int index) {
if (index < limit) {
doRecursive(sb, limit, index + 1);
sb.append(Integer.toString(index));
}
}
}
I know this question is quite old but there is actually a Save Actions plugin for IntelliJ that can be configured to format the code automatically.
Internet explorer has a reset to factory button and luckily so does chrome! try the link below and let us know. the other option is to stop chrome and delete the c:\users\%username%\appdata\local\google folder entirely then reinstall chrome but this will loose all you local settings and data.

I wanted specific control over this issue, so this is what I did:
From a fragment or activity, hide your other views (that aren't needed while the keyboard is up), then restore them to solve this problem:
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
rootView.getWindowVisibleDisplayFrame(r);
int heightDiff = rootView.getRootView().getHeight() - (r.bottom - r.top);
if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
//ok now we know the keyboard is up...
view_one.setVisibility(View.GONE);
view_two.setVisibility(View.GONE);
} else {
//ok now we know the keyboard is down...
view_one.setVisibility(View.VISIBLE);
view_two.setVisibility(View.VISIBLE);
}
}
});
Try to see, if the service "SQL Server (MSSQLSERVER)" it's started, this solved my problem.

I noticed a case, where resulting path names exceeded the maximum allowed length (just like here).
I have replaced xcopy by robocopy for the affected post build event; robocopy seems to handle paths slightly different and was able to complete the copy task that xcopy was unable to handle.
You can use this simple ES6 method
const lastChar = (str) => str.split('').reverse().join(',').replace(',', '')[str.length === str.length + 1 ? 1 : 0];_x000D_
_x000D_
_x000D_
// example_x000D_
console.log(lastChar("linto.yahoo.com."));
_x000D_
This will work in every browsers.
Use this instead
function timedRefresh(timeoutPeriod) {
setTimeout("location.reload(true);",timeoutPeriod);
}

Both Abstraction and Encapsulation are two of the four basic OOP concepts which allow you to model real-world things into objects so that you can implement them in your program and code. Many beginners get confused between Abstraction and Encapsulation because they both look very similar. If you ask someone what is Abstraction, he will tell that it's an OOP concept which focuses on relevant information by hiding unnecessary detail, and when you ask about Encapsulation, many will tell that it's another OOP concept which hides data from outside world. The definitions are not wrong as both Abstraction and Encapsulation does hide something, but the key difference is on intent.
Abstraction hides complexity by giving you a more abstract picture, a sort of 10,000 feet view, while Encapsulation hides internal working so that you can change it later. In other words, Abstraction hides details at the design level, while Encapsulation hides details at the implementation level.
event.target
is of type EventTarget
which doesn't always have a value. If it's a DOM element you need to cast it to the correct type:
handleChange(event) {
this.setState({value: (event.target as HTMLInputElement).value});
}
This will infer the "correct" type for the state variable as well though being explicit is probably better
df.sort($"ColumnName".desc).show()
For Microsoft office 2013
"Last but one" of a non empty row:
=OFFSET(Sheet5!$C$1,COUNTA(Sheet5!$C:$C)-2,0)
"Last" non empty row:

s = '123'
issubclass(s.__class__, str)
I think this code should work fine
while ($personCount < 10) {
$result = $personCount . "people ';
$personCount++;
}
// do not understand why do you need the (+) with the result.
echo $result;
You need to check out the attr
method in the jQuery docs. You are misusing it. What you are doing within the if statements simply replaces all image tags src
with the string specified in the 2nd parameter.
A better way to approach replacing a series of images source would be to loop through each and check it's source.
Example:
$('img').each(function () {
var curSrc = $(this).attr('src');
if ( curSrc === 'http://example.com/smith.gif' ) {
$(this).attr('src', 'http://example.com/johnson.gif');
}
if ( curSrc === 'http://example.com/williams.gif' ) {
$(this).attr('src', 'http://example.com/brown.gif');
}
});
Posting parameters Using POST:-
URL url;
URLConnection urlConn;
DataOutputStream printout;
DataInputStream input;
url = new URL (getCodeBase().toString() + "env.tcgi");
urlConn = url.openConnection();
urlConn.setDoInput (true);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type","application/json");
urlConn.setRequestProperty("Host", "android.schoolportal.gr");
urlConn.connect();
//Create JSONObject here
JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");
The part which you missed is in the the following... i.e., as follows..
// Send POST output.
printout = new DataOutputStream(urlConn.getOutputStream ());
printout.writeBytes(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
printout.flush ();
printout.close ();
The rest of the thing you can do it.
I have faced the similar issue on my website hosted on IIS. This issue generally because of IIS Application pool settings. As application pool recycle after some time that caused the issue for me.
Following steps help me to fix the issue:
Then try again . It will solve your issue.
You could also use the iframe method, although this is not cross browser compatible (eg. not working in chromium or android and probably others -> instead prompts to download). It works with dataURL's and normal URLS, not sure if the other examples work with dataURLS (please let me know if the other examples work with dataURLS?)
<iframe class="page-icon preview-pane" frameborder="0" height="352" width="396" src="data:application/pdf;base64, ..DATAURLHERE!... "></iframe>
I'm currently working on such a statement and figured out another fact to notice: INSERT OR REPLACE will replace any values not supplied in the statement. For instance if your table contains a column "lastname" which you didn't supply a value for, INSERT OR REPLACE will nullify the "lastname" if possible (constraints allow it) or fail.
After having to tackle this issue myself, I would like to build upon user854301's answer.
Mongoose ^4.13.8 I was able to use a function called toConstructor()
which allowed me to avoid building the query multiple times when filters are applied. I know this function is available in older versions too but you'll have to check the Mongoose docs to confirm this.
The following uses Bluebird promises:
let schema = Query.find({ name: 'bloggs', age: { $gt: 30 } });
// save the query as a 'template'
let query = schema.toConstructor();
return Promise.join(
schema.count().exec(),
query().limit(limit).skip(skip).exec(),
function (total, data) {
return { data: data, total: total }
}
);
Now the count query will return the total records it matched and the data returned will be a subset of the total records.
Please note the () around query() which constructs the query.
I meet the similar issue, but it auto fixed after i reboot my Ubuntu PC,for I install some Ubuntu(12.04)app update,which leads to this issue.
The mostly used StringUtils class is the Apache Commons Lang StringUtils (org.apache.commons.lang3.StringUtils). To use this class you first have to download the Apache Commons Lang3 package then you have to add it to your project libraries.
You can go to this link to get more details: http://examples.javacodegeeks.com/core-java/apache/commons/lang3/stringutils/org-apache-commons-lang3-stringutils-example/
You can use TreeMap
which will store values in sorted form.
Map <String, String> map = new TreeMap <String, String>();
Please remove . from your target it should be a id
<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>
Also you have to give your modal id like below
<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">
These two commands should work fine.
virtualenv -p python2 myenv
(For python2)
virtualenv -p python3 myenv

I found this to be an issue when joining but you might find this blog useful in understanding how Joins work in the back. How Joins Work..
[Edited] @Shree Thank you for pointing that out. On the paragraph of Merge Join. It mentions on how joins work...
Like hash join, merge join consists of two steps. First, both tables of the join are sorted on the join attribute. This can be done with just two passes through each table via an external merge sort. Finally, the result tuples are generated as the next ordered element is pulled from each table and the join attributes are compared
.
I'm sure you know that a std::vector<X>
stores a whole bunch of X
objects, right? But if you have a std::map<X, Y>
, what it actually stores is a whole bunch of std::pair<const X, Y>
s. That's exactly what a map is - it pairs together the keys and the associated values.
When you iterate over a std::map
, you're iterating over all of these std::pair
s. When you dereference one of these iterators, you get a std::pair
containing the key and its associated value.
std::map<std::string, int> m = /* fill it */;
auto it = m.begin();
Here, if you now do *it
, you will get the the std::pair
for the first element in the map.
Now the type std::pair
gives you access to its elements through two members: first
and second
. So if you have a std::pair<X, Y>
called p
, p.first
is an X
object and p.second
is a Y
object.
So now you know that dereferencing a std::map
iterator gives you a std::pair
, you can then access its elements with first
and second
. For example, (*it).first
will give you the key and (*it).second
will give you the value. These are equivalent to it->first
and it->second
.
Gentil Kiwi's answer is correct. He developed this mimikatz tool that is able to retrieve non-exportable private keys.
However, his instructions are outdated. You need:
Download the lastest release from https://github.com/gentilkiwi/mimikatz/releases
Run the cmd with admin rights in the same machine where the certificate was requested
Change to the mimikatz bin directory (Win32 or x64 version)
Run mimikatz
Follow the wiki instructions and the .pfx file (protected with password mimikatz) will be placed in the same folder of the mimikatz bin

Let is a mathematical statement that was adopted by early programming languages like Scheme and Basic. Variables are considered low level entities not suitable for higher levels of abstraction, thus the desire of many language designers to introduce similar but more powerful concepts like in Clojure, F#, Scala, where let
might mean a value, or a variable that can be assigned, but not changed, which in turn lets the compiler catch more programming errors and optimize code better.
JavaScript has had var
from the beginning, so they just needed another keyword, and just borrowed from dozens of other languages that use let
already as a traditional keyword as close to var
as possible, although in JavaScript let
creates block scope local variable instead.
Essentially, you want to override the __init__
method of models.Model
so that you keep a copy of the original value. This makes it so that you don't have to do another DB lookup (which is always a good thing).
class Person(models.Model):
name = models.CharField()
__original_name = None
def __init__(self, *args, **kwargs):
super(Person, self).__init__(*args, **kwargs)
self.__original_name = self.name
def save(self, force_insert=False, force_update=False, *args, **kwargs):
if self.name != self.__original_name:
# name changed - do something here
super(Person, self).save(force_insert, force_update, *args, **kwargs)
self.__original_name = self.name
int[] n=new int[5];
for (int i = 0; i < 5; i++)
{
n[i] = i + 100;
}
foreach (int j in n)
{
int i = j - 100;
Console.WriteLine("Element [{0}]={1}", i, j);
i++;
}
If none of the other solutions work for you, double check that your scroll view actually is a UIScrollView
in Interface Builder.
At some point in the last few days, my UIScrollView
spontaneously changed type to a UIView
, even though its class said UIScrollView
in the inspector. I'm using Xcode 5.1 (5B130a)
.
You can either create a new scroll view and copy the measurements, settings and constraints from the old view, or you can manually change your view to a UIScrollView
in the xib
file. I did a compare and found the following differences:
Original:
<scrollView clipsSubviews="YES" multipleTouchEnabled="YES" contentMode="scaleToFill" directionalLockEnabled="YES" bounces="NO" pagingEnabled="YES" showsHorizontalScrollIndicator="NO" showsVerticalScrollIndicator="NO" translatesAutoresizingMaskIntoConstraints="NO" id="Wsk-WB-LMH">
...
</scrollView>
After type spontaneously changed:
<view clearsContextBeforeDrawing="NO" contentMode="scaleToFill" translatesAutoresizingMaskIntoConstraints="NO" customClass="UIScrollView" id="qRn-TP-cXd">
...
</view>
So I replaced the <view>
line with my original <scrollView>
line.
I also replaced the view's close tag </view>
with </scrollView>
.
Be sure to keep the id the same as the current view, in this case: id="qRn-TP-cXd".
I also had to flush the xib from Xcode's cache by deleting the app's derived data:
Xcode->Window->Organizer->Projects
, choose your project, on the Derived Data line, click Delete...Or if using a device:
Xcode->Window->Organizer->Device
, choose your device->Applications, choose your app, click (-)Now clean the project, and remove the app from the simulator/device:
Xcode->Product->Clean
Simulator/device->press
and hold the app->click
the (X) to remove itYou should then be able to build and run your app and have scrolling functionality again.
P.S. I didn't have to set the scroll view's content size in viewDidLayoutSubviews
or turn off auto layout, but YMMV.
You should not use your domain models
in your views. ViewModels
are the correct way to do it.
You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.
If you never heard of viewmodels, take a look at this.
no, but it runs fine on win64, and can create win64 .EXEs
For MySQL, MariaDB
ALTER TABLE [table name] MODIFY COLUMN [column name] [data type] NULL
Use MODIFY COLUMN
instead of ALTER COLUMN
.
white-space: normal;
word-wrap: break-word;
"Both" worked for me.
This is something that is done by Django itself when building a form from a model. It is using the _meta attribute, but as Bernhard noted, it uses both _meta.fields and _meta.many_to_many. Looking at django.forms.models.fields_for_model, this is how you could do it:
opts = model._meta
for f in sorted(opts.fields + opts.many_to_many):
print '%s: %s' % (f.name, f)
Apart from varargs or overloading, you could consider to aggregate your arguments in a std::vector or other containers (std::map for example). Something like this:
template <typename T> void f(std::vector<T> const&);
std::vector<int> my_args;
my_args.push_back(1);
my_args.push_back(2);
f(my_args);
In this way you would gain type safety and the logical meaning of these variadic arguments would be apparent.
Surely this approach can have performance issues but you should not worry about them unless you are sure that you cannot pay the price. It is a sort of a a "Pythonic" approach to c++ ...
Do you mean byte size or string length?
Byte size is measured with strlen()
, whereas string length is queried using mb_strlen()
. You can use substr()
to trim a string to X bytes (note that this will break the string if it has a multi-byte encoding - as pointed out by Darhazer in the comments) and mb_substr()
to trim it to X characters in the encoding of the string.
Here's a more concise approach...
df['a_bsum'] = df.groupby('A')['B'].transform(sum)
df.sort(['a_bsum','C'], ascending=[True, False]).drop('a_bsum', axis=1)
The first line adds a column to the data frame with the groupwise sum. The second line performs the sort and then removes the extra column.
Result:
A B C
5 baz -2.301539 True
2 baz -0.528172 False
1 bar -0.611756 True
4 bar 0.865408 False
3 foo -1.072969 True
0 foo 1.624345 False
NOTE: sort
is deprecated, use sort_values
instead
If you just deleted the file, know that VSCode 1.52 (Dec. 2020) will support:
Undo file operations in Explorer
Explorer now supports Undo and Redo for all file operations: delete, rename, copy, move, new file and new folder.
Make sure the focus is in the Explorer and trigger the Undo or Redo commands and your last file operation will be undone or redone respectively.
Keep in mind that we have separate undo stacks for the editor and the explorer and we choose which one to undo based on focus.
Supporting Ruivo's answer, yes you have to declare method as "public" to be able to use in Android's XML onclick - I am developing an app targeting from API Level 8 (minSdk...) to 16 (targetSdk...).
I was declaring my method as private and it caused error, just declaring it as public works great.
keyCode and which represent the actual keyboard key pressed in the form of a numeric value. The reason both exist is that keyCode is available within Internet Explorer while which is available in W3C browsers like FireFox.
charCode is similar, but in this case you retrieve the Unicode value of the character pressed. For example, the letter "A."
The JavaScript expression:
var keyCode = e.keyCode ? e.keyCode : e.charCode;
Essentially says the following:
If the e.keyCode property exists, set variable keyCode to its value. Otherwise, set variable keyCode to the value of the e.charCode property.
Note that retrieving the keyCode or charCode properties typically involve figuring out differences between the event models in IE and in W3C. Some entails writing code like the following:
/*
get the event object: either window.event for IE
or the parameter e for other browsers
*/
var evt = window.event ? window.event : e;
/*
get the numeric value of the key pressed: either
event.keyCode for IE for e.which for other browsers
*/
var keyCode = evt.keyCode ? evt.keyCode : e.which;
EDIT: Corrections to my explanation of charCode as per Tor Haugen's comments.
Change this line
filename1 = datetime.now().strftime("%Y%m%d-%H%M%S")
To
filename1 = datetime.datetime.now().strftime("%Y%m%d-%H%M%S")
Note the extra datetime
. Alternatively, change your
import datetime
to from datetime import datetime
I like @ninjagecko's answer the most.
This would also work:
for Python 2.x
isinstance(n, (int, long, float))
Python 3.x doesn't have long
isinstance(n, (int, float))
there is also type complex for complex numbers
import math
from collections import namedtuple
Point = namedtuple("Point", ["x", "y"])
def get_angle(p1: Point, p2: Point) -> float:
"""Get the angle of this line with the horizontal axis."""
dx = p2.x - p1.x
dy = p2.y - p1.y
theta = math.atan2(dy, dx)
angle = math.degrees(theta) # angle is in (-180, 180]
if angle < 0:
angle = 360 + angle
return angle
For testing I let hypothesis generate test cases.
import hypothesis.strategies as s
from hypothesis import given
@given(s.floats(min_value=0.0, max_value=360.0))
def test_angle(angle: float):
epsilon = 0.0001
x = math.cos(math.radians(angle))
y = math.sin(math.radians(angle))
p1 = Point(0, 0)
p2 = Point(x, y)
assert abs(get_angle(p1, p2) - angle) < epsilon
You can also use the WriteLiteral method
If you want to print XML directly onto the screen you can use TransformerFactory
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(conn.getInputStream());
TransformerFactory transformerFactory= TransformerFactory.newInstance();
Transformer xform = transformerFactory.newTransformer();
// that’s the default xform; use a stylesheet to get a real one
xform.transform(new DOMSource(doc), new StreamResult(System.out));
One can also do this :
<xsl:text disable-output-escaping="yes"><![CDATA[ ]]></xsl:text>
sp_help
is what you're looking for.
From Sybase online documentation on the sp_help system procedure:
Description
Reports information about a database object (any object listed in sysobjects) and about system or user-defined datatypes, as well as computed columns and function-based indexes. Column displays optimistic_index_lock.
Syntax
sp_help [objname]
[...]
Here is the (partial) output for the publishers table (pasted from Using sp_help on database objects):
Name Owner Object_type Create_date

Still quoting Using sp_help on database objects:
If you execute sp_help without supplying an object name, the resulting report shows each object in sysobjects, along with its name, owner, and object type. Also shown is each user-defined datatype in systypes and its name, storage type, length, whether null values are allowed, and any defaults or rules bound to it. The report also notes if any primary or foreign key columns have been defined for a table or view.
reverse the string and then, in a second pass, reverse each word...
in c#, completely in-place without additional arrays:
static char[] ReverseAllWords(char[] in_text)
{
int lindex = 0;
int rindex = in_text.Length - 1;
if (rindex > 1)
{
//reverse complete phrase
in_text = ReverseString(in_text, 0, rindex);
//reverse each word in resultant reversed phrase
for (rindex = 0; rindex <= in_text.Length; rindex++)
{
if (rindex == in_text.Length || in_text[rindex] == ' ')
{
in_text = ReverseString(in_text, lindex, rindex - 1);
lindex = rindex + 1;
}
}
}
return in_text;
}
static char[] ReverseString(char[] intext, int lindex, int rindex)
{
char tempc;
while (lindex < rindex)
{
tempc = intext[lindex];
intext[lindex++] = intext[rindex];
intext[rindex--] = tempc;
}
return intext;
}
It seems that the compiler is better in optimizing a switch-statement than an if-statement.
The compiler doesn't know if the order of evaluating the if-statements is important to you, and can't perform any optimizations there. You could be calling methods in the if-statements, influencing variables. With the switch-statement it knows that all clauses can be evaluated at the same time and can put them in whatever order is most efficient.
Here's a small comparison:

Yes, it will block the other method because synchronized method applies to the WHOLE class object as pointed .... but anyway it will block the other thread execution ONLY while performing the sum in whatever method addA or addB it enters, because when it finish ... the one thread will FREE the object and the other thread will access the other method and so on perfectly working.
I mean the "synchronized" is made precisely for blocking the other thread from accessing another while in a specific code execution. SO FINALLY THIS CODE WILL WORK FINE.
As a final note, if there is an 'a' and 'b' variables, not just an unique variable 'a' or whatever other name, there is no need to synchronize this methods cause it is perfectly safe accesing other var (Other memory location).
class X {
private int a;
private int b;
public void addA(){
a++;
}
public void addB(){
b++;
}}
Will work as well
You could use Canvas
in HTML, simply add a canva
<canvas id="locations" width="400" height="300" style="border:1px solid #d3d3d3;">
Your browser can't read canvas</canvas>
And in Javascript (only an example, that will draw a rectangle on the picture)
var c = document.getElementById("locations");
var ctx = c.getContext("2d");
var img = new Image();
img.src = '{main_photo}';
img.onload = function() { // after the pic is loaded
ctx.drawImage(this,0,0); // add the picture
ctx.beginPath(); // start the rectangle
ctx.moveTo(50,50);
ctx.lineTo(200,50);
ctx.lineTo(200,200);
ctx.lineTo(50,200);
ctx.lineTo(50,50);
ctx.strokeStyle = "sienna"; // set color
ctx.stroke(); // apply color
ctx.lineWidth = 5;
// ctx.closePath();
};
I created a function to check if times in an array overlap somehow:
/**
* Function to check if there are overlapping times in an array of \DateTime objects.
*
* @param $ranges
*
* @return \DateTime[]|bool
*/
public function timesOverlap($ranges) {
foreach ($ranges as $k1 => $t1) {
foreach ($ranges as $k2 => $t2) {
if ($k1 != $k2) {
/* @var \DateTime[] $t1 */
/* @var \DateTime[] $t2 */
$a = $t1[0]->getTimestamp();
$b = $t1[1]->getTimestamp();
$c = $t2[0]->getTimestamp();
$d = $t2[1]->getTimestamp();
if (($c >= $a && $c <= $b) || $d >= $a && $d <= $b) {
return true;
}
}
}
}
return false;
}
Random always return the same sequence. It's used for shuffling arrays and other operations as permutations.
To get different sequences, it's necessary initialize the sequence in some position, called "seed".
The randomSting get the random number in the i position (seed = -229985452) of the "random" sequence. Then uses the ASCII code for the next 27 character in the sequence after the seed position until this value are equal to 0. This return the "hello". The same operation is done for "world".
I think that the code did not work for any other words. The guy that programmed that knows the random sequence very well.
It's very great geek code!
Maybe specifying a width would work. When you position:absolute
an element, it's width will shrink to the contents I believe.
ARIA (Accessible Rich Internet Applications) defines a way to make Web content and Web applications more accessible to people with disabilities.
The hidden
attribute is new in HTML5 and tells browsers not to display the element. The aria-hidden
property tells screen-readers if they should ignore the element. Have a look at the w3 docs for more details:
https://www.w3.org/WAI/PF/aria/states_and_properties#aria-hidden
Using these standards can make it easier for disabled people to use the web.
The problem is you either haven't closed your if
or you need an elseif
:
create procedure checando(
in nombrecillo varchar(30),
in contrilla varchar(30),
out resultado int)
begin
if exists (select * from compas where nombre = nombrecillo and contrasenia = contrilla) then
set resultado = 0;
elseif exists (select * from compas where nombre = nombrecillo) then
set resultado = -1;
else
set resultado = -2;
end if;
end;
The "Lines" property of a TextBox is an array of strings. By definition, you cannot add elements to an existing string[]
, like you can to a List<string>
. There is simply no method available for the purpose. You must instead create a new string[]
based on the current Lines reference, and assign it to Lines.
Using a little Linq (.NET 3.5 or later):
textBox1.Lines = textBox.Lines.Concat(new[]{"Some Text"}).ToArray();
This code is fine for adding one new line at a time based on user interaction, but for initializing a textbox with a few dozen new lines, it will perform very poorly. If you're setting the initial value of a TextBox, I would either set the Text property directly using a StringBuilder (as other answers have mentioned), or if you're set on manipulating the Lines property, use a List to compile the collection of values and then convert it to an array to assign to Lines:
var myLines = new List<string>();
myLines.Add("brown");
myLines.Add("brwn");
myLines.Add("brn");
myLines.Add("brow");
myLines.Add("br");
myLines.Add("brw");
...
textBox1.Lines = myLines.ToArray();
Even then, because the Lines array is a calculated property, this involves a lot of unnecessary conversion behind the scenes.
Try using background-size
but using TWO ARGUMENTS One for the width and the other one for the height
background-image:url('../images/bg.png');
background-repeat:no-repeat;
background-size: 100% 100%; // Here the first argument will be the width
// and the second will be the height.
background-position:center;
LENGTH()
does return the string length (just verified). I suppose that your data is padded with blanks - try
SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;
instead.
As OraNob
mentioned, another cause could be that CHAR
is used in which case LENGTH()
would also return the column width, not the string length. However, the TRIM()
approach also works in this case.
This is what I did:
\begin{frame}{series of images}
\begin{center}
\begin{overprint}
\only<2>{\includegraphics[scale=0.40]{image1.pdf}}
\hspace{-0.17em}\only<3>{\includegraphics[scale=0.40]{image2.pdf}}
\hspace{-0.34em}\only<4>{\includegraphics[scale=0.40]{image3.pdf}}
\hspace{-0.17em}\only<5>{\includegraphics[scale=0.40]{image4.pdf}}
\only<2-5>{\mbox{\structure{Figure:} something}}
\end{overprint}
\end{center}
\end{frame}
Cast the operands to floats:
float ans = (float)a / (float)b;
I think you need separately date parts like (day, Month, Year)
DateTime today = DateTime.Today;
Will not work for your case. You can get date separately so you don't need variable today
to be as a DateTime
Type, so lets just give today
variable int
Type because the day is only int. So today is 10 March 2020 then the result of
int today = DateTime.Today.Day;
int month = DateTime.Today.Month;
int year = DateTime.Today.Year;
MessageBox.Show(today.ToString()+ " - this is day. "+month.ToString()+ " - this is month. " + year.ToString() + " - this is year");
would be "10 - this is day. 3 - this is month. 2020 - this is year"
Your immediate question of how to make it pull master, you need to do what it says. Specify the refspec to pull from in your branch config.
[branch "master"]
merge = refs/heads/master
The WHERE
clause is always conceptually applied (the execution plan can do what it wants, obviously) prior to the GROUP BY
. It must come before the GROUP BY
in the query, and acts as a filter before things are SUM
med, which is how most of the answers here work.
You should also be aware of the optional HAVING
clause which must come after the GROUP BY
. This can be used to filter on the resulting properties of groups after GROUP
ing - for instance HAVING SUM(Amount) > 0

The necessary method is Mockito#verify:
public static <T> T verify(T mock,
VerificationMode mode)
mock
is your mocked object and mode
is the VerificationMode
that describes how the mock should be verified. Possible modes are:
verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");
You'll need these static imports from the Mockito
class in order to use the verify
method and these verification modes:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
So in your case the correct syntax will be:
Mockito.verify(mock, times(4)).send()
This verifies that the method send
was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.
If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode
. A simple
verify(mock).someMethod("was called once");
would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");
.
It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");
, but we can write
verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");
instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.
I'm new to python too. Here is something that looks like will do what you want to
axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`
I believe this decides the size of the canvas.
The envdir
utility provides an easy way to do this. envdir
uses files to represent environment variables, with file names mapping to env var names, and file contents mapping to env var values. If the file contents contain newlines, so will the env var.
try this.. I had it too but now it solved in XP..
C:\ YourFolder >set path=C:\Program Files\Java\jdk1.7.0_09\bin;
C:\ YourFolder >javac YourCode.java
my_hash = {:a => 5}
my_hash[:key] = "value"
In my vue project in visual studio code, I had to set this in /config/index.js. Change it in the:
module.exports = {
dev: {
// Paths
assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {},
host: 'localhost', // can be overwritten by process.env.HOST
port: 8090, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
autoOpenBrowser: false,
errorOverlay: true,
notifyOnErrors: true,
poll: false
}
}
If you are using Jackson, then you can use the @JsonProperty
annotation to customize the name of a given JSON property.
Therefore, you just have to annotate the entity fields with the @JsonProperty
annotation and provide a custom JSON property name, like this:
@Entity
public class City {
@Id
@JsonProperty("value")
private Long id;
@JsonProperty("label")
private String name;
//Getters and setters omitted for brevity
}
JSON-B is the standard binding layer for converting Java objects to and from JSON. If you are using JSON-B, then you can override the JSON property name via the @JsonbProperty
annotation:
@Entity
public class City {
@Id
@JsonbProperty("value")
private Long id;
@JsonbProperty("label")
private String name;
//Getters and setters omitted for brevity
}
If you are splitting from Linux, you can still reassemble in Windows.
copy /b file1 + file2 + file3 + file4 filetogether
You can use /* tslint:disable-next-line */
to locally disable tslint. However, as this is a compiler error disabling tslint might not help.
You can always temporarily cast $
to any
:
delete ($ as any).summernote.options.keyMap.pc.TAB
which will allow you to access whatever properties you want.
Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:
if (false) {
// @ts-ignore: Unreachable code error
console.log("hello");
}
Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any
instead as that better expresses intent.
If it ain't broke - fix it till it is...just kidding :)
But seriously BackgroundWorker is probably very similar to what you already have, had you started with it from the beginning maybe you would have saved some time - but at this point I don't see the need. Unless something isn't working, or you think your current code is hard to understand, then I would stick with what you have.
Your best bet is to use
table.YourClass tr:hover td {
background-color: #FEFEFE;
}
Rows aren't fully support for background color but cells are, using the combination of :hover and the child element will yield the results you need.
Illegal offset type errors occur when you attempt to access an array index using an object or an array as the index key.
Example:
$x = new stdClass();
$arr = array();
echo $arr[$x];
//illegal offset type
Your $xml
array contains an object or array at $xml->entry[$i]->source
for some value of $i
, and when you try to use that as an index key for $s
, you get that warning. You'll have to make sure $xml
contains what you want it to and that you're accessing it correctly.
use this
NSString *myregex = @"<[^>]*>"; //regex to remove any html tag
NSString *htmlString = @"<html>bla bla</html>";
NSString *stringWithoutHTML = [hstmString stringByReplacingOccurrencesOfRegex:myregex withString:@""];
don't forget to include this in your code : #import "RegexKitLite.h" here is the link to download this API : http://regexkit.sourceforge.net/#Downloads
Well, in my case the problem had a different cause, the Windows path Length Check this.
I was installing a library on a virtualenv
which made the path get longer. As the library was installed, it created some files under site-packages
. This made the path exceed Windows limit throwing this error.
Hope it helps someone =)
I am not very sure if what i did was right, but it worked anyways. I renamed repo2 folder present inside repo1, and committed the changes. In my case it was just one repo which i wanted to merge , so this approach worked. Later on, some path changes were done.
You can do something like this to read 10 bytes:
char buffer[10];
read(STDIN_FILENO, buffer, 10);
remember read() doesn't add '\0'
to terminate to make it string (just gives raw buffer).
To read 1 byte at a time:
char ch;
while(read(STDIN_FILENO, &ch, 1) > 0)
{
//do stuff
}
and don't forget to #include <unistd.h>
, STDIN_FILENO
defined as macro in this file.
There are three standard POSIX file descriptors, corresponding to the three standard streams, which presumably every process should expect to have:
Integer value Name
0 Standard input (stdin)
1 Standard output (stdout)
2 Standard error (stderr)
So instead STDIN_FILENO
you can use 0.
Edit:
In Linux System you can find this using following command:
$ sudo grep 'STDIN_FILENO' /usr/include/* -R | grep 'define'
/usr/include/unistd.h:#define STDIN_FILENO 0 /* Standard input. */
Notice the comment /* Standard input. */
Here is a much simpler way:
Create a new branch
On your new branch do a git merge master
- this will merge your committed (not pushed) changes to your new branch
Delete you local master branch git branch -D master
Use -D
instead of -d
because you want to force delete the branch.
Just do a git fetch
on your master branch and do a git pull
on your master branch to ensure you have your teams latest code.
No.
Not a documented 100% supported way. There is an approach sometimes used for calculating running totals called "quirky update" that suggests that it might update in order of clustered index if certain conditions are met but as far as I know this relies completely on empirical observation rather than any guarantee.
But what version of SQL Server are you on? If SQL2005+ you might be able to do something with row_number
and a CTE (You can update the CTE)
With cte As
(
SELECT id,Number,
ROW_NUMBER() OVER (ORDER BY id DESC) AS RN
FROM Test
)
UPDATE cte SET Number=RN
An alternative solution for preventing functions to change the user par
. You can set the default parameters early on the function, so that the graphical parameters and layout will not be changed during the function execution. See ?on.exit
for further details.
on.exit(layout(1))
opar<-par(no.readonly=TRUE)
on.exit(par(opar),add=TRUE,after=FALSE)
use 'marginTop'
instead of MarginTop
$(this).find('.info').animate({ 'marginTop': '-50px', opacity: 0.5 }, 1000);
Use the shell function test
:
foo:
test $(something)
Usage:
$ make foo
test
Makefile:2: recipe for target 'foo' failed
make: *** [foo] Error 1
$ make foo something=x
test x
You can do this with this library. https://github.com/itmor/events-js
const events = new Events();
events.add({
blockIsHidden: () => {
if ($('div').css('display') === 'none') return true;
}
});
function printText () {
console.log('The block has become hidden!');
}
events.on('blockIsHidden', printText);
You can use moment.js for that, it will convert DateTime object into valid Javascript formated date:
moment(DateOfBirth).format('DD-MMM-YYYY'); // put format as you want
Output: 28-Apr-1993
Hope it will help you :)
I guess if you change the id_no
, some of the foreign keys would not reference anything, thus the constraint violation.
You could add initialy deffered
to the foreign keys, so the constraints are checked when the changes are commited
OpenID and OAuth are each HTTP-based protocols for authentication and/or authorization. Both are intended to allow users to perform actions without giving authentication credentials or blanket permissions to clients or third parties. While they are similar, and there are proposed standards to use them both together, they are separate protocols.
OpenID is intended for federated authentication. A client accepts an identity assertion from any provider (although clients are free to whitelist or blacklist providers).
OAuth is intended for delegated authorization. A client registers with a provider, which provides authorization tokens which it will accept to perform actions on the user's behalf.
OAuth is currently better suited for authorization, because further interactions after authentication are built into the protocol, but both protocols are evolving. OpenID and its extensions could be used for authorization, and OAuth can be used for authentication, which can be thought of as a no-op authorization.
If you want to get K dummy variables, instead of K-1, try:
dummies = table(1:length(year),as.factor(year))
Best,
And I like this way:
$cars = array
(
array("Volvo",22),
array("BMW",15),
array("Saab",5),
array("Land Rover",17)
);
There are a lot of answers here. And it's old, but this is for anyone coming here via google. In jQuery each function
return false;
is like break
.
just
return;
is like continue
These will emulate the behavior of break and continue.
Use below code in your xml file
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#000000"
android:dividerHeight="1dp">
</ListView>
The below worked really good for me. I patched together all the above answers plus read about displaying object properties in the following link and came up with the below short read about printing objects
add the following text to a file named print_object.ps1:
$date = New-Object System.DateTime
Write-Output $date | Get-Member
Write-Output $date | Select-Object -Property *
open powershell command prompt, go to the directory where that file exists and type the following:
powershell -ExecutionPolicy ByPass -File is_port_in_use.ps1 -Elevated
Just substitute 'System.DateTime' with whatever object you wanted to print. If the object is null, nothing will print out.
Google recommend that you don't use any of them, source.
There is no need to use entity references like
&mdash
,&rdquo
, or☺
, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.
Is there a reason you can't simply use "
?

Take a look at Simple JavaScript Inheritance and Inheritance Patterns in JavaScript.
The simplest method is probably functional inheritance but there are pros and cons.
Frank Heikens answer will only update database ownership. Often, you also want to update ownership of contained objects (including tables). Starting with Postgres 8.2, REASSIGN OWNED is available to simplify this task.
IMPORTANT EDIT!
Never use REASSIGN OWNED
when the original role is postgres
, this could damage your entire DB instance. The command will update all objects with a new owner, including system resources (postgres0, postgres1, etc.)
First, connect to admin database and update DB ownership:
psql
postgres=# REASSIGN OWNED BY old_name TO new_name;
This is a global equivalent of ALTER DATABASE
command provided in Frank's answer, but instead of updating a particular DB, it change ownership of all DBs owned by 'old_name'.
The next step is to update tables ownership for each database:
psql old_name_db
old_name_db=# REASSIGN OWNED BY old_name TO new_name;
This must be performed on each DB owned by 'old_name'. The command will update ownership of all tables in the DB.
Easiest way I found to receive current time in milliseconds in MySql:
SELECT (UNIX_TIMESTAMP(NOW(3)) * 1000)
Since MySql 5.6.
Chrome, Firefox, Vivaldi and Safari support getEventListeners(domElement)
in their Developer Tools console.
For majority of the debugging purposes, this could be used.
Below is a very good reference to use it: https://developers.google.com/web/tools/chrome-devtools/console/utilities#geteventlisteners
A modified python version of @danack's PHP generate script. It generates all files & folders that live inside of build/
to the parent directory, replacing all {{placeholder}}
matches. You need to cd
into build/
before running the script.
File structure
build/

What error is it giving you?
If you do exactly this:
data = json.loads('{"lat":444, "lon":555}')
Then:
data['lat']
SHOULD NOT give you any error at all.
If you came across this while installing WAMP64 on Windows 10. Check if data folder in MySQL folder is missing. My WAMP 3.2.3 version installation failed to create such a folder. So wamp icon was orange (1 of 2 services running).
A quick fix was to run this command from MySQL location.
C:\wamp64\bin\mysql\mysql5.7.31\bin\
mysqld --initialize-insecure
If you're saying you might have different clients as well, there are problems with classic ADO if SET NOCOUNT is not set ON.
One I experience regularly: if a stored procedure executes a number of statements (and thus a number of "xxx rows affected" messages are returned), ADO seems not to handle this and throws the error "Cannot change the ActiveConnection property of a Recordset object which has a Command object as its source."
So I generally advocate setting it ON unless there's a really really good reason not to. you may have found the really really good reason which I need to go and read into more.
bananascript.com used to give me best results.
The reason for this is that you are trying to use an IntentService. Here is the line from the API Docs
The IntentService does the following:
Stops the service after all start requests have been handled, so you never have to call stopSelf().
Thus if you want your service to run indefinitely i suggest you extend the Service class instead. However this does not guarantee your service will run indefinitely. Your service will still have a chance of being killed by the kernel in a state of low memory if it is low priority.So you have two options:
1)Keep it running in the foreground by calling the startForeground()
method.
2)Restart the service if it gets killed.
Here is a part of the example from the docs where they talk about restarting the service after it is killed
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
// For each start request, send a message to start a job and deliver the
// start ID so we know which request we're stopping when we finish the job
Message msg = mServiceHandler.obtainMessage();
msg.arg1 = startId;
mServiceHandler.sendMessage(msg);
// If we get killed, after returning from here, restart
return START_STICKY;
}
Luckily, Python has this built-in :)

patrick dw's answer is right on.
For kicks and giggles I thought I would post a simple way to return an array of all the IDs.
var arrayOfIds = $.map($(".myClassName"), function(n, i){
return n.id;
});
alert(arrayOfIds);
Here is a simple solution that serializes a server-side C# enum to JSON and uses the result to populate a client-side <select>
element. This works for both simple enums and bitflag enums.
I have included the end-to-end solution because I think most people wanting to serialize a C# enum to JSON will also probably be using it to fill a <select>
drop-down.
Here goes:
Example Enum
public enum Role
{
None = Permission.None,
Guest = Permission.Browse,
Reader = Permission.Browse| Permission.Help ,
Manager = Permission.Browse | Permission.Help | Permission.Customise
}
A complex enum that uses bitwise ORs to generate a permissions system. So you can't rely on the simple index [0,1,2..] for the integer value of the enum.
Server Side - C#
Get["/roles"] = _ =>
{
var type = typeof(Role);
var data = Enum
.GetNames(type)
.Select(name => new
{
Id = (int)Enum.Parse(type, name),
Name = name
})
.ToArray();
return Response.AsJson(data);
};
The code above uses the NancyFX framework to handle the Get request. It uses Nancy's Response.AsJson()
helper method - but don't worry, you can use any standard JSON formatter as the enum has already been projected into a simple anonymous type ready for serialization.
Generated JSON
[
{"Id":0,"Name":"None"},
{"Id":2097155,"Name":"Guest"},
{"Id":2916367,"Name":"Reader"},
{"Id":4186095,"Name":"Manager"}
]
Client Side - CoffeeScript
fillSelect=(id, url, selectedValue=0)->
$select = $ id
$option = (item)-> $ "<option/>",
{
value:"#{item.Id}"
html:"#{item.Name}"
selected:"selected" if item.Id is selectedValue
}
$.getJSON(url).done (data)->$option(item).appendTo $select for item in data
$ ->
fillSelect "#role", "/roles", 2916367
HTML Before
<select id="role" name="role"></select>
HTML After
<select id="role" name="role">
<option value="0">None</option>
<option value="2097155">Guest</option>
<option value="2916367" selected="selected">Reader</option>
<option value="4186095">Manager</option>
</select>
If you provide your JVM the Spring profile there should be no problems:
java -Dspring.profiles.active=development -jar yourApplication.jar
Also see Spring-Documentation:
69.5 Set the active Spring profiles
The Spring Environment has an API for this, but normally you would set a System property (spring.profiles.active) or an OS environment variable (SPRING_PROFILES_ACTIVE). E.g. launch your application with a -D argument (remember to put it before the main class or jar archive):
$ java -jar -Dspring.profiles.active=production demo-0.0.1-SNAPSHOT.jar
In Spring Boot you can also set the active profile in application.properties, e.g.
spring.profiles.active=production
A value set this way is replaced by the System property or environment variable setting, but not by the SpringApplicationBuilder.profiles() method. Thus the latter Java API can be used to augment the profiles without changing the defaults.
See Chapter 25, Profiles in the ‘Spring Boot features’ section for more information.
Use this function. Don't forget to save the WhatsApp Number on your mobile before sending trigger the function.

Intent i = new Intent(Intent.ACTION_SENDTO,uri);
i.setPackage("com.whatsapp");
startActivity(i);
}
Just put ojdbc6.jar
in class path, so that we can fix CallbaleStatement
exception:
oracle.jdbc.driver.T4CPreparedStatement.setBinaryStream(ILjava/io/InputStream;J)V)
in Oracle.
None of the answers here worked for me either.
However, I could fix the error by removing the Android classpath container (in my case Android 4.4) from ALL attached libraries except the main application and then exporting the APK. The library projects won't compile anymore, but the jar file still exists and the APK is getting deployed. I'm not sure what's the reason for this behaviour.
Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).
Otherwise, you might want to go with another JS library like jQuery or Mootools.
The default web folder for nginx depends on how you installed it, but normally it's in these locations:
/usr/local/nginx/html
/usr/nginx/html
You can try the following:
gitk --all
You can tell gitk
what to display using anything that git rev-list
understands, so if you just want a few branches, you can do:
gitk master origin/master origin/experiment
... or more exotic things like:
gitk --simplify-by-decoration --all
For me it was the apache server hosted on a t2.micro linux EC2 instance, not the EC2 instance itself.
I fixed it by doing:
sudo su
service httpd restart
It permanently comments out that code so the compiler will never compile it.
The coder can later change the #ifdef to have that code compile in the program if he wants to.
It's exactly like the code doesn't exist.
You can try getting a list from the map object by just iterating each item in the object and store it in a different variable.
a = map(chr, [66, 53, 0, 94])
b = [item for item in a]
print(b)
>>>['B', '5', '\x00', '^']
Just give full path to exclusion file: eg..
-- no - - - - -xcopy c:\t1 c:\t2 /EXCLUDE:list-of-excluded-files.txt
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\list-of-excluded-files.txt
In this example the file would be located " C:\list-of-excluded-files.txt "
or...
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\mybatch\list-of-excluded-files.txt
In this example the file would be located " C:\mybatch\list-of-excluded-files.txt "
Full path fixes syntax error.
According to the documentation, use a relative path for a local jar dependency as follows:
dependencies {
implementation files('libs/something_local.jar')
}
I liked qiao's first answer very much!
The only thing missing here is to mark the vertexes as visited.
Why we need to do it?
Lets imagine that there is another node number 13 connected from node 11. Now our goal is to find node 13.
After a little bit of a run the queue will look like this:
[[1, 2, 6], [1, 3, 10], [1, 4, 7], [1, 4, 8], [1, 2, 5, 9], [1, 2, 5, 10]]
Note that there are TWO paths with node number 10 at the end.
Which means that the paths from node number 10 will be checked twice. In this case it doesn't look so bad because node number 10 doesn't have any children.. But it could be really bad (even here we will check that node twice for no reason..)
Node number 13 isn't in those paths so the program won't return before reaching to the second path with node number 10 at the end..And we will recheck it..
All we are missing is a set to mark the visited nodes and not to check them again..
This is qiao's code after the modification:
graph = {
1: [2, 3, 4],
2: [5, 6],
3: [10],
4: [7, 8],
5: [9, 10],
7: [11, 12],
11: [13]
}
def bfs(graph_to_search, start, end):
queue = [[start]]
visited = set()
while queue:
# Gets the first path in the queue
path = queue.pop(0)
# Gets the last node in the path
vertex = path[-1]
# Checks if we got to the end
if vertex == end:
return path
# We check if the current node is already in the visited nodes set in order not to recheck it
elif vertex not in visited:
# enumerate all adjacent nodes, construct a new path and push it into the queue
for current_neighbour in graph_to_search.get(vertex, []):
new_path = list(path)
new_path.append(current_neighbour)
queue.append(new_path)
# Mark the vertex as visited
visited.add(vertex)
print bfs(graph, 1, 13)
The output of the program will be:
[1, 4, 7, 11, 13]
Without the unneccecery rechecks..
$("[style*=block]").hide();
It is the area of the marker. I mean if you have s1 = 1000
and then s2 = 4000
, the relation between the radius of each circle is: r_s2 = 2 * r_s1
. See the following plot:
plt.scatter(2, 1, s=4000, c='r')
plt.scatter(2, 1, s=1000 ,c='b')
plt.scatter(2, 1, s=10, c='g')
I had the same doubt when I saw the post, so I did this example then I used a ruler on the screen to measure the radii.
To get a list of tables for the current database in DB2 -->
Connect to the database:
db2 connect to DATABASENAME user USER using PASSWORD
Run this query:
db2 LIST TABLES
This is the equivalent of SHOW TABLES in MySQL.
You may need to execute 'set schema myschema' to the correct schema before you run the list tables command. By default upon login your schema is the same as your username - which often won't contain any tables. You can use 'values current schema' to check what schema you're currently set to.
I created this simple one a while back. The main challenge I had was to create a good build environment - a makefile that would compile and link/deploy everything without having to use the GUI. For the code, here is the header:
class AMLed
{
private:
uint8_t _ledPin;
long _turnOffTime;
public:
AMLed(uint8_t pin);
void setOn();
void setOff();
// Turn the led on for a given amount of time (relies
// on a call to check() in the main loop()).
void setOnForTime(int millis);
void check();
};
And here is the main source
AMLed::AMLed(uint8_t ledPin) : _ledPin(ledPin), _turnOffTime(0)
{
pinMode(_ledPin, OUTPUT);
}
void AMLed::setOn()
{
digitalWrite(_ledPin, HIGH);
}
void AMLed::setOff()
{
digitalWrite(_ledPin, LOW);
}
void AMLed::setOnForTime(int p_millis)
{
_turnOffTime = millis() + p_millis;
setOn();
}
void AMLed::check()
{
if (_turnOffTime != 0 && (millis() > _turnOffTime))
{
_turnOffTime = 0;
setOff();
}
}
It's more prettily formatted here: http://amkimian.blogspot.com/2009/07/trivial-led-class.html
To use, I simply do something like this in the .pde file:
#include "AM_Led.h"
#define TIME_LED 12 // The port for the LED
AMLed test(TIME_LED);
take look at my example
<tocheading language="EN">
<subj-group>
<subject>Editors Choice</subject>
<subject>creative common</subject>
</subj-group>
</tocheading>
now how to check if creative common
is exist
tocheading/subj-group/subject/text() = 'creative common'
hope this help you
The Interactive Stepthrough PHP Debugger implemented as a SAPI module which can give give you complete control over the environment without impacting the functionality or performance of your code. It aims to be a lightweight, powerful, easy to use debugging platform for PHP 5.4+ and it's shipped out-of-box with PHP 5.6.
Features includes:
See the screenshots:
Home page: http://phpdbg.com/
This is very easy to use library (actually a file) to debug your PHP scripts.
The only thing that you need to do is to include one file as below (at the beginning on your code):
require('php_error.php');
\php_error\reportErrors();
Then all errors will give you info such as backtrace, code context, function arguments, server variables, etc. For example:

If your system supports DTrace dynamic tracing (installed by default on OS X) and your PHP is compiled with the DTrace probes enabled (--enable-dtrace
) which should be by default, this command can help you to debug PHP script with no time:
sudo dtrace -qn 'php*:::function-entry { printf("%Y: PHP function-entry:\t%s%s%s() in %s:%d\n", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2); }'
So given the following alias has been added into your rc files (e.g. ~/.bashrc
, ~/.bash_aliases
):
alias trace-php='sudo dtrace -qn "php*:::function-entry { printf(\"%Y: PHP function-entry:\t%s%s%s() in %s:%d\n\", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2); }"'
you may trace your script with easy to remember alias: trace-php
.
Here is more advanced dtrace script, just save it into dtruss-php.d
, make it executable (chmod +x dtruss-php.d
) and run:
#!/usr/sbin/dtrace -Zs
# See: https://github.com/kenorb/dtruss-lamp/blob/master/dtruss-php.d
#pragma D option quiet
php*:::compile-file-entry
{
printf("%Y: PHP compile-file-entry:\t%s (%s)\n", walltimestamp, basename(copyinstr(arg0)), copyinstr(arg1));
}
php*:::compile-file-return
{
printf("%Y: PHP compile-file-return:\t%s (%s)\n", walltimestamp, basename(copyinstr(arg0)), basename(copyinstr(arg1)));
}
php*:::error
{
printf("%Y: PHP error message:\t%s in %s:%d\n", walltimestamp, copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2);
}
php*:::exception-caught
{
printf("%Y: PHP exception-caught:\t%s\n", walltimestamp, copyinstr(arg0));
}
php*:::exception-thrown
{
printf("%Y: PHP exception-thrown:\t%s\n", walltimestamp, copyinstr(arg0));
}
php*:::execute-entry
{
printf("%Y: PHP execute-entry:\t%s:%d\n", walltimestamp, basename(copyinstr(arg0)), (int)arg1);
}
php*:::execute-return
{
printf("%Y: PHP execute-return:\t%s:%d\n", walltimestamp, basename(copyinstr(arg0)), (int)arg1);
}
php*:::function-entry
{
printf("%Y: PHP function-entry:\t%s%s%s() in %s:%d\n", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2);
}
php*:::function-return
{
printf("%Y: PHP function-return:\t%s%s%s() in %s:%d\n", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2);
}
php*:::request-shutdown
{
printf("%Y: PHP request-shutdown:\t%s at %s via %s\n", walltimestamp, basename(copyinstr(arg0)), copyinstr(arg1), copyinstr(arg2));
}
php*:::request-startup
{
printf("%Y, PHP request-startup:\t%s at %s via %s\n", walltimestamp, basename(copyinstr(arg0)), copyinstr(arg1), copyinstr(arg2));
}

Here is simple usage:
sudo dtruss-php.d
.php -r "phpinfo();"
.To test that, you can go to any docroot with index.php
and run PHP builtin server by:
php -S localhost:8080
After that you can access the site at http://localhost:8080/ (or choose whatever port is convenient for you). From there access some pages to see the trace output.
Note: Dtrace is available on OS X by default, on Linux you probably need dtrace4linux or check for some other alternatives.
See: Using PHP and DTrace at php.net
Alternatively check for SystemTap tracing by installing SystemTap SDT development package (e.g. yum install systemtap-sdt-devel
).
Here is example script (all_probes.stp
) for tracing all core PHP static probe points throughout the duration of a running PHP script with SystemTap:
probe process("sapi/cli/php").provider("php").mark("compile__file__entry") {
printf("Probe compile__file__entry\n");
printf(" compile_file %s\n", user_string($arg1));
printf(" compile_file_translated %s\n", user_string($arg2));
}
probe process("sapi/cli/php").provider("php").mark("compile__file__return") {
printf("Probe compile__file__return\n");
printf(" compile_file %s\n", user_string($arg1));
printf(" compile_file_translated %s\n", user_string($arg2));
}
probe process("sapi/cli/php").provider("php").mark("error") {
printf("Probe error\n");
printf(" errormsg %s\n", user_string($arg1));
printf(" request_file %s\n", user_string($arg2));
printf(" lineno %d\n", $arg3);
}
probe process("sapi/cli/php").provider("php").mark("exception__caught") {
printf("Probe exception__caught\n");
printf(" classname %s\n", user_string($arg1));
}
probe process("sapi/cli/php").provider("php").mark("exception__thrown") {
printf("Probe exception__thrown\n");
printf(" classname %s\n", user_string($arg1));
}
probe process("sapi/cli/php").provider("php").mark("execute__entry") {
printf("Probe execute__entry\n");
printf(" request_file %s\n", user_string($arg1));
printf(" lineno %d\n", $arg2);
}
probe process("sapi/cli/php").provider("php").mark("execute__return") {
printf("Probe execute__return\n");
printf(" request_file %s\n", user_string($arg1));
printf(" lineno %d\n", $arg2);
}
probe process("sapi/cli/php").provider("php").mark("function__entry") {
printf("Probe function__entry\n");
printf(" function_name %s\n", user_string($arg1));
printf(" request_file %s\n", user_string($arg2));
printf(" lineno %d\n", $arg3);
printf(" classname %s\n", user_string($arg4));
printf(" scope %s\n", user_string($arg5));
}
probe process("sapi/cli/php").provider("php").mark("function__return") {
printf("Probe function__return: %s\n", user_string($arg1));
printf(" function_name %s\n", user_string($arg1));
printf(" request_file %s\n", user_string($arg2));
printf(" lineno %d\n", $arg3);
printf(" classname %s\n", user_string($arg4));
printf(" scope %s\n", user_string($arg5));
}
probe process("sapi/cli/php").provider("php").mark("request__shutdown") {
printf("Probe request__shutdown\n");
printf(" file %s\n", user_string($arg1));
printf(" request_uri %s\n", user_string($arg2));
printf(" request_method %s\n", user_string($arg3));
}
probe process("sapi/cli/php").provider("php").mark("request__startup") {
printf("Probe request__startup\n");
printf(" file %s\n", user_string($arg1));
printf(" request_uri %s\n", user_string($arg2));
printf(" request_method %s\n", user_string($arg3));

The problem defintely relates to the use of (in this case) the max() function. Any aggregation function used during a join (e.g. to retrieve the max or min or avg value from a joined table) will cause the error. And the same applies to using subqueries instead of joins (as in the original code).
This is incredibly annoying (and unjustified!) as it is a reasonably common thing to want to do. I've also had to use temp tables to get around it (pull the aggregated value into a temp table with an insert statement, then join to this table with your update, then drop the temp table).

If you can use the jQuery validation plugin you can do it like so:
Html:
<input type="file" name="photo" id="photoInput" />
JavaScript:
$.validator.addMethod('imagedim', function(value, element, param) {
var _URL = window.URL;
var img;
if ((element = this.files[0])) {
img = new Image();
img.onload = function () {
console.log("Width:" + this.width + " Height: " + this.height);//this will give you image width and height and you can easily validate here....
return this.width >= param
};
img.src = _URL.createObjectURL(element);
}
});
The function is passed as ab onload function.
The code is taken from here
The only way to remove an inline "display:none" via jQuery's css-api is by resetting it with the empty string (null
does NOT work btw!!).
According to the jQuery docu this is the general way to "remove" a once set inline style property.
$("#mydiv").css("display","");
or
$("#mydiv").css({display:""});
should do the trick properly.
IMHO there is a method missing in jQuery that could be called "unhide" or "reveal" which instead of just setting another inline style property unsets the display value properly as described above. Or maybe hide()
should store the initial inline value and show()
should restore that...
In my situation, some problems happened with my node package. So I run npm audit fix
and it fixed all problems
Just another example, almost one liner.
var date = new Date();_x000D_
console.log( (date.getMonth() < 9 ? '0': '') + (date.getMonth()+1) );
_x000D_
There is this possibility like Aman Virk mentioned:
var options = {
chartArea:{left:10,top:20,width:"100%",height:"100%"}
};
But keep in mind that the padding and margin aren't there to bother you. If you have the possibility to switch between different types of charts like a ColumnChart and the one with vertical columns then you need some margin for displaying the labels of those lines.
If you take away that margin then you will end up showing only a part of the labels or no labels at all.
So if you just have one chart type then you can change the margin and padding like Arman said. But if it's possible to switch don't change them.
If you are not sure what to do and are starting from scratch then Maven can help get you started.
By following the the below steps you can get a new war project setup perfectly in eclipse.
mvn archetype:generate
mvn eclipse:eclipse
mvn package
or deploy it by setting up a server in eclipse and simply adding adding the project to the server.As some others have said the downside of using maven is that you have to use the maven conventions. But I think if you are just starting out, learning the conventions is a good idea before you start making your own. There's nothing to stop you changing/refactoring to your own preferred method at a later point.
Hope this helps.
want to use model in view as:
{{ Product::find($id) }}
you can use in view:
<?php
$tmp = \App\Product::find($id);
?>
{{ $tmp->name }}
Hope this will help you
I wrote a function to do this because I like my code to tell me if something is wrong. This function will explicitly tell you which column names don't match and if you have a type mismatch. Then it will do its best to combine the data.frames anyway. The limitation is that you can only combine two data.frames at a time.
### combines data frames (like rbind) but by matching column names
# columns without matches in the other data frame are still combined
# but with NA in the rows corresponding to the data frame without
# the variable
# A warning is issued if there is a type mismatch between columns of
# the same name and an attempt is made to combine the columns
combineByName <- function(A,B) {
a.names <- names(A)
b.names <- names(B)
all.names <- union(a.names,b.names)
print(paste("Number of columns:",length(all.names)))
a.type <- NULL
for (i in 1:ncol(A)) {
a.type[i] <- typeof(A[,i])
}
b.type <- NULL
for (i in 1:ncol(B)) {
b.type[i] <- typeof(B[,i])
}
a_b.names <- names(A)[!names(A)%in%names(B)]
b_a.names <- names(B)[!names(B)%in%names(A)]
if (length(a_b.names)>0 | length(b_a.names)>0){
print("Columns in data frame A but not in data frame B:")
print(a_b.names)
print("Columns in data frame B but not in data frame A:")
print(b_a.names)
} else if(a.names==b.names & a.type==b.type){
C <- rbind(A,B)
return(C)
}
C <- list()
for(i in 1:length(all.names)) {
l.a <- all.names[i]%in%a.names
pos.a <- match(all.names[i],a.names)
typ.a <- a.type[pos.a]
l.b <- all.names[i]%in%b.names
pos.b <- match(all.names[i],b.names)
typ.b <- b.type[pos.b]
if(l.a & l.b) {
if(typ.a==typ.b) {
vec <- c(A[,pos.a],B[,pos.b])
} else {
warning(c("Type mismatch in variable named: ",all.names[i],"\n"))
vec <- try(c(A[,pos.a],B[,pos.b]))
}
} else if (l.a) {
vec <- c(A[,pos.a],rep(NA,nrow(B)))
} else {
vec <- c(rep(NA,nrow(A)),B[,pos.b])
}
C[[i]] <- vec
}

I was facing the same issue while auto-wiring the class from one of my jar file. I fixed the issue by using @Lazy annotation:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Lazy;
@Autowired
@Lazy
private IGalaxyCommand iGalaxyCommand;
You can use the Attribute.IsDefined method
https://msdn.microsoft.com/en-us/library/system.attribute.isdefined(v=vs.110).aspx
if(Attribute.IsDefined(YourProperty,typeof(YourAttribute)))
{
//Conditional execution...
}
You could provide the property you're specifically looking for or you could iterate through all of them using reflection, something like:
PropertyInfo[] props = typeof(YourClass).GetProperties();
@echo off
set log=%time% %date%
echo %log%
That is a batch for saving the date and time as a temporary variable, and displaying it. In a hurry, I don't have time to write a script to open a txt, maybe later.
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.
