On Linux Fedora30 several versions of the full java JDK are available, specifically package names:
java-1.8.0-openjdk-devel.x86_64
java-11-openjdk-devel.x86_64
Once installed, they are found in: /usr/lib/jvm
To select the location/directory of a full development JDK (which is different from the simpler runtime only JRE) look for entries:
ls -ld java*openjdk*
Here are two good choices, which are links to specific versions, where you will have to select the version:
/usr/lib/jvm/java-1.8.0-openjdk
/usr/lib/jvm/java-11-openjdk
When I conceive an application in Android, I see it this way:
To do that, you only need the Back button or the Home button of your phone (either by short or long press) and the notification bar.
When I exit my application, I only use the Back button until I am out of it or the Home button.
That's how most of the applications are conceived I think. But if I need some sort of session or connection, I made it clear to the user with a login/logout button and notification (title bar or anything else). This is a rather different style than the pure "exit" style application.
On PCs, you have a multi-GUI desktop, and on Android, you obviously have multi-tasks, but you only display one app at a time (I don't consider widgets here ^^). And on a mobile phone, at anytime, you could have a notification for something more important than what you are doing.
So the whole concept of an application rely on something different that "enter application - work - exit application".
I had this same problem, but I'm a Linux user.
I resolved the problem by reattempting the installation with adminstrator privileges. [For those Linux users reading this, I ran studio.sh
with sudo

For Kotlin, if you want to be sure that the format is "Aaaaaaaaa" you can use :

For reading "plain" CSV files in Java, there is a library called OpenCSV, available here: http://opencsv.sourceforge.net/
EDITED ANSWER PER DAVID'S RESPONSE:
Here's a kind of hackish way. I'm guessing there's an easier way. But you could suppress the bar labels and the plot text of the labels by saving the bar positions from barplot
and do a little tweaking up and down. Here's an example with the mtcars data set:
x <- barplot(table(mtcars$cyl), xaxt="n")
labs <- paste(names(table(mtcars$cyl)), "cylinders")
text(cex=1, x=x-.25, y=-1.25, labs, xpd=TRUE, srt=45)
You can use an XMLHttpRequest to load a page into a div (or any other element of your page really). An exemple function would be:
function loadPage(){
if (window.XMLHttpRequest){
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else{
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("ID OF ELEMENT YOU WANT TO LOAD PAGE IN").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("POST","WEBPAGE YOU WANT TO LOAD",true);
xmlhttp.send();
}
If your sever is capable, you could also use PHP to do this, but since you're asking for an HTML5 method, this should be all you need.
Here is my code for that:
$('#date-daily').datepicker().on('changeDate', function(e) {
//$('#other-input').val(e.format(0,"dd/mm/yyyy"));
//alert(e.date);
//alert(e.format(0,"dd/mm/yyyy"));
//console.log(e.date);
});
Just uncomment the one you prefer. The first option changes the value of other input element. The second one alerts the date with datepicker default format. The third one alerts the date with your own custom format. The last option outputs to log (default format date).
It's your choice to use the e.date , e.dates (for múltiple date input) or e.format(...).

As a couple of answers have pointed out, I believe there is some some misunderstanding of multi tier vs MVC architecture.
Multi tier architecture involves breaking your application into tiers/layers (e.g. presentation, business logic, data access)
MVC is an architectural style for the presentation layer of an application. For non trivial applications, business logic/business rules/data access should not be placed directly into Models, Views, or Controllers. To do so would be placing business logic in your presentation layer and thus reducing reuse and maintainability of your code.
The model is a very reasonable choice choice to place business logic, but a better/more maintainable approach is to separate your presentation layer from your business logic layer and create a business logic layer and simply call the business logic layer from your models when needed. The business logic layer will in turn call into the data access layer.
I would like to point out that it is not uncommon to find code that mixes business logic and data access in one of the MVC components, especially if the application was not architected using multiple tiers. However, in most enterprise applications, you will commonly find multi tier architectures with an MVC architecture in place within the presentation layer.

You can simply use Query Builder rather than Eloquent, this code directly update your data in the database :) This is a sample:
DB::table('post')
->where('id', 3)
->update(['title' => "Updated Title"]);
You can check the documentation here for more information: http://laravel.com/docs/5.0/queries#updates
select u from UserGroup ug inner join ug.user u
where ug.group_id = :groupId
order by u.lastname
As a named query:
@NamedQuery(
name = "User.findByGroupId",
query =
"SELECT u FROM UserGroup ug " +
"INNER JOIN ug.user u WHERE ug.group_id = :groupId ORDER BY u.lastname"
)
Use paths in the HQL statement, from one entity to the other. See the Hibernate documentation on HQL and joins for details.
You can use isin

In [2]: df
Out[2]:
A B
0 5 1
1 6 2
2 3 3
3 4 5
In [3]: df[df['A'].isin([3, 6])]
Out[3]:
A B
1 6 2
2 3 3
And to get the opposite use ~

Since Python 3.5, subprocess.run() is recommended over subprocess.check_output():
>>> subprocess.run(['cat','/tmp/text.txt'], stdout=subprocess.PIPE).stdout
b'First line\nSecond line\n'
Since Python 3.7, instead of the above, you can use capture_output=true
parameter to capture stdout and stderr:
>>> subprocess.run(['cat','/tmp/text.txt'], capture_output=True).stdout
b'First line\nSecond line\n'
Also, you may want to use universal_newlines=True
or its equivalent since Python 3.7 text=True
to work with text instead of binary:
>>> stdout = subprocess.run(['cat', '/tmp/text.txt'], capture_output=True, text=True).stdout
>>> print(stdout)
First line
Second line
See subprocess.run() documentation for more information.
Better to use a HashSet
than an ArrayList
when you are checking for existence of a value.
Java docs for HashSet
says: "This class offers constant time performance for the basic operations (add, remove, contains and size)"
ArrayList.contains()
might have to iterate the whole list to find the instance you are looking for.

No Tracking LINQ to Entities queries
Usage of AsNoTracking() is recommended when your query is meant for read operations. In these scenarios, you get back your entities but they are not tracked by your context.This ensures minimal memory usage and optimal performance
Pros
- Improved performance over regular LINQ queries.
- Fully materialized objects.
- Simplest to write with syntax built into the programming language.
Cons
- Not suitable for CUD operations.
- Certain technical restrictions, such as: Patterns using DefaultIfEmpty for OUTER JOIN queries result in more complex queries than simple OUTER JOIN statements in Entity SQL.
- You still can’t use LIKE with general pattern matching.

You should use datetime
object, not str
.
>>> from datetime import datetime
>>> cr_date = datetime(2013, 10, 31, 18, 23, 29, 227)
>>> cr_date.strftime('%m/%d/%Y')
'10/31/2013'
To get the datetime object from the string, use datetime.datetime.strptime
:
>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
datetime.datetime(2013, 10, 31, 18, 23, 29, 227)
>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f').strftime('%m/%d/%Y')
'10/31/2013'
Here's another method if you can safely use CSS3's transform
property:
.fixed-horizontal-center

position: fixed;
top: 100px; /* or whatever top you need */
left: 50%;
width: auto;
-webkit-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-ms-transform: translateX(-50%);
-o-transform: translateX(-50%);
transform: translateX(-50%);
}
...or if you want both horizontal AND vertical centering:
.fixed-center
{
position: fixed;
top: 50%;
left: 50%;
width: auto;
height: auto;
-webkit-transform: translate(-50%,-50%);
-moz-transform: translate(-50%,-50%);
-ms-transform: translate(-50%,-50%);
-o-transform: translate(-50%,-50%);
transform: translate(-50%,-50%);

https://github.com/neopixl/PixlUI provides an EditText
with a method
myEditText.disableCopyAndPaste()
.
And it's works on the old API
var str = "Hello, this is Mike (example)";
alert(str.replace(/\s*\(.*?\)\s*/g, ''));
That'll also replace excess whitespace before and after the parentheses.
Just been working on something very similar, I am not an expert but I thought I would share the commands I have used. I had a multi column csv which I only required 4 columns out of and then I needed to reorder them.
My file was pipe '|' delimited but that can be swapped out.
LC_ALL=C cut -d$'|' -f1,2,3,8,10 ./file/location.txt | sed -E "s/(.*)\|(.*)\|(.*)\|(.*)\|(.*)/\3\|\5\|\1\|\2\|\4/" > ./newcsv.csv
Admittedly it is really rough and ready but it can be tweaked to suit!
It works on either option tag or text field:
$("#idname option[value='option1']").remove();
Use functional operation for faster iteration.
team1.keySet().forEach((key) -> {
System.out.println(key);
});
Consider this question asked at StackOverflow today:

Add the var
keyword before the variable name.
Here's a nice fun LINQ example.

.ToArray();
}
In makefile language $@
means "name of the target", so rm -f $@

eval $cmd
For the follow-on question of how to escape *
since it has special meaning when it's naked or in double quoted strings: use single quotes.

1 - You can use the same activity as both dialog and full screen, dynamically:
Call setTheme(android.R.style.Theme_Dialog)
before calling setContentView(...)
and super.oncreate()
in your Activity.
2 - If you don't plan to change the activity theme style you can use
<activity android:theme="@android:style/Theme.Dialog" />

First, checkout to your Branch3:
git checkout Branch3
Then merge the Branch1:
git merge Branch1
And if you want the updated commits of Branch1 on Branch2, you are probaly looking for git rebase
git checkout Branch2
git rebase Branch1
This will update your Branch2 with the latest updates of Branch1.

Here's the official line on the problem (I couldn't find the latest, but I don't think the situation has changed for later versions of .net)
The InstallUtil.exe
tool is simply a wrapper around some reflection calls against the installer component(s) in your service. As such, it really doesn't do much but exercise the functionality these installer components provide. Marc Gravell's solution simply provides a means to do this from the command line so that you no longer have to rely on having InstallUtil.exe
on the target machine.
Here's my step-by-step that based on Marc Gravell's solution.
How to make a .NET Windows Service start right after the installation?
For the simple answer, you can use Link
component from react-router
, instead of button
. There is ways to change the route in JS, but seems you don't need that here.
<span className="input-group-btn">
<Link to="/login" />Click to login</Link>
</span>
To do it programmatically in 1.0.x, you do like this, inside your clickHandler function:
this.history.pushState(null, 'login');
Taken from upgrade doc here
You should have this.history
placed on your route handler component by react-router
. If it child component beneath that mentioned in routes
definition, you may need pass that down further
The accepted answer is correct. I would like to provide an example to elaborate it a bit to those who aren't familiar with promise
.
Example:
In my example, I need to replace the src
attributes of img
tags with different mirror urls if available before rendering the content.
var img_tags = content.querySelectorAll('img');
function checkMirrorAvailability(url) {
// blah blah
return promise;
}
function changeSrc(success, y, response) {
if (success === true) {
img_tags[y].setAttribute('src', response.mirror_url);
}
else {
console.log('No mirrors for: ' + img_tags[y].getAttribute('src'));
}
}
var promise_array = [];
for (var y = 0; y < img_tags.length; y++) {
var img_src = img_tags[y].getAttribute('src');
promise_array.push(
checkMirrorAvailability(img_src)
.then(
// a callback function only accept ONE argument.
// Here, we use `.bind` to pass additional arguments to the
// callback function (changeSrc).
// successCallback
changeSrc.bind(null, true, y),
// errorCallback
changeSrc.bind(null, false, y)
)
);
}
$q.all(promise_array)
.then(
function() {
console.log('all promises have returned with either success or failure!');
render(content);
}
// We don't need an errorCallback function here, because above we handled
// all errors.
);
Explanation:
From AngularJS docs:
The then
method:
then(successCallback, errorCallback, notifyCallback) – regardless of when the promise was or will be resolved or rejected, then calls one of the success or error callbacks asynchronously as soon as the result is available. The callbacks are called with a single argument: the result or rejection reason.
$q.all(promises)
Combines multiple promises into a single promise that is resolved when all of the input promises are resolved.
The promises
param can be an array of promises.
About bind()
, More info here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind
A common problem is that node-gyp requires Python 2.x and if your system's python
points to 3.x, it will fail to compile bson
, without warning. You can fix this by setting a python
global key in your npm config that points to the 2.x executable on your system. For example, on Arch Linux:
npm config -g set python "/usr/bin/python2"
This is quite simple with vanilla JavaScript...
document.querySelector('#selector')
i think the problem is that there is no data in the success-function because the request breaks up with an 401 error in your case and thus has no success.
if you use
$.ajax({
url: "https://app.asana.com/-/api/0.1/workspaces/",
type: 'GET',
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
});
there will be your 401 code i think (this link says so)
You don't need to use arrays.
JSON values can be arrays, objects, or primitives (numbers or strings).
You can write JSON like this:
{
"stuff": {
"onetype": [
{"id":1,"name":"John Doe"},
{"id":2,"name":"Don Joeh"}
],
"othertype": {"id":2,"company":"ACME"}
},
"otherstuff": {
"thing": [[1,42],[2,2]]
}
}
You can use it like this:
obj.stuff.onetype[0].id
obj.stuff.othertype.id
obj.otherstuff.thing[0][1] //thing is a nested array or a 2-by-2 matrix.
//I'm not sure whether you intended to do that.

and the DB field names match those on the HTML form)
<input type="checkbox" name="tag_1" id="tag_1" value="yes" <?php echo ($dbvalue['tag_1']==1 ? 'checked' : '');?>>
If you're looking for the code to do everything for you, you've come to the wrong place.
This is the one liner you're looking fo:
DateTime? d = DateTime.TryParse("some date text", out DateTime dt) ? dt : null;
If you want to make it a proper TryParse pseudo-extension method, you can do this:
public static bool TryParse(string text, out DateTime? dt)
{
if (DateTime.TryParse(text, out DateTime date))
{
dt = date;
return true;
}
else
{
dt = null;
return false;
}
}
The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:
Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.
There are many variants to versioning. It all boils down to personal preference.
For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.
You could do this with generics trick, but it still is vulnerable to what Jon Skeet wrote:
public interface IHasDefaultConstructor<T> where T : IHasDefaultConstructor<T>, new()
{
}
Class that implements this interface must have parameterless constructor:
public class A : IHasDefaultConstructor<A> //Notice A as generic parameter
{
public A(int a) { } //compile time error
}
SELECT sys.columns.name AS ColumnName, tables.name AS TableName
FROM sys.columns
JOIN sys.tables ON sys.columns.object_id = tables.object_id
For most it is a breeze, however like you I had a difficult time installing jq
The best resources I found are: https://stedolan.github.io/jq/download/ and http://macappstore.org/jq/
However neither worked for me. I run python 2 & 3, and use brew in addition to pip, as well as Jupyter. I was only successful after brew uninstall jq then updating brew and rebooting my system
What worked for me was removing all previous installs then pip install jq
You can also use either jQuery .not()
method or :not()
selector:
if ($('#checkSurfaceEnvironment').not(':checked').length) {
// do stuff for not selected
}
From the jQuery API documentation for the :not()
selector:
The .not() method will end up providing you with more readable selections than pushing complex selectors or variables into a :not() selector filter. In most cases, it is a better choice.
@Frode F. gave the right answer.
By the Way Invoke-WebRequest
also prints you the 200 OK
and a lot of bla, bla, bla... which might be useful but I still prefer the Invoke-RestMethod
which is lighter.
Also, keep in mind that you need to use | ConvertTo-Json
for the body only, not the header:
$body = @{
"UserSessionId"="12345678"
"OptionalEmail"="[email protected]"
} | ConvertTo-Json
$header = @{
"Accept"="application/json"
"connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
"Content-Type"="application/json"
}
Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML
and you can then append a | ConvertTo-HTML
at the end of the request for better readability
My first answer!
This will set the safemode switch:
bcdedit /set {current} safeboot minimal
with networking:
bcdedit /set {current} safeboot network
then reboot the machine with
shutdown /r
to put back in normal mode via dos:
bcdedit /deletevalue {current} safeboot
Codes below is my approach under anaconda python 2.7 plus a package name "pydot-ng" to making a PDF file with decision rules. I hope it is helpful.
from sklearn import tree
clf = tree.DecisionTreeClassifier(max_leaf_nodes=n)
clf_ = clf.fit(X, data_y)
feature_names = X.columns
class_name = clf_.classes_.astype(int).astype(str)
def output_pdf(clf_, name):
from sklearn import tree
from sklearn.externals.six import StringIO
import pydot_ng as pydot
dot_data = StringIO()
tree.export_graphviz(clf_, out_file=dot_data,
feature_names=feature_names,
class_names=class_name,
filled=True, rounded=True,
special_characters=True,
node_ids=1,)
graph = pydot.graph_from_dot_data(dot_data.getvalue())
graph.write_pdf("%s.pdf"%name)
output_pdf(clf_, name='filename%s'%n)
to read an array
, you can also utilize "each
" method of jQuery
:
$.each($("input[name^='card']"), function(index, val){
console.log(index + " : " + val);
});
bonus: you can also read objects through this method.
use className->function(); instead className::function() ;
Actually, you don't need to modify the object
prototype. The following should work to 'obtain' unique ids for any object, efficiently enough.
var __next_objid=1;
function objectId(obj) {
if (obj==null) return null;
if (obj.__obj_id==null) obj.__obj_id=__next_objid++;
return obj.__obj_id;
}
If the table was already created, and you were lazy enough not to specify the columns in the fields names input, then all you have to do is to select the empty columns at right to the file content and delete them.
You can also use it
export function diffDateAndToString(small: Date, big: Date) {
// To calculate the time difference of two dates
const Difference_In_Time = big.getTime() - small.getTime()
// To calculate the no. of days between two dates
const Days = Difference_In_Time / (1000 * 3600 * 24)
const Mins = Difference_In_Time / (60 * 1000)
const Hours = Mins / 60
const diffDate = new Date(Difference_In_Time)
console.log({ date: small, now: big, diffDate, Difference_In_Days: Days, Difference_In_Mins: Mins, Difference_In_Hours: Hours })
var result = ''
if (Mins < 60) {
result = Mins + 'm'
} else if (Hours < 24) result = diffDate.getMinutes() + 'h'
else result = Days + 'd'
return { result, Days, Mins, Hours }
}
results in { result: '30d', Days: 30, Mins: 43200, Hours: 720 }
#include<iostream>

This was my own attempt, but I'll use the answer by annakata as it seems much cleaner:
function AddUrlParameter(sourceUrl, parameterName, parameterValue, replaceDuplicates)
{
if ((sourceUrl == null) || (sourceUrl.length == 0)) sourceUrl = document.location.href;
var urlParts = sourceUrl.split("?");
var newQueryString = "";
if (urlParts.length > 1)
{
var parameters = urlParts[1].split("&");
for (var i=0; (i < parameters.length); i++)
{
var parameterParts = parameters[i].split("=");
if (!(replaceDuplicates && parameterParts[0] == parameterName))
{
if (newQueryString == "")
newQueryString = "?";
else
newQueryString += "&";
newQueryString += parameterParts[0] + "=" + parameterParts[1];
}
}
}
if (newQueryString == "")
newQueryString = "?";
else
newQueryString += "&";
newQueryString += parameterName + "=" + parameterValue;
return urlParts[0] + newQueryString;
}
Also, I found this jQuery plugin from another post on stackoverflow, and if you need more flexibility you could use that: http://plugins.jquery.com/project/query-object
I would think the code would be (haven't tested):
return $.query.parse(sourceUrl).set(parameterName, parameterValue).toString();
Steven Pribilinskiy's answer drops leading zeroes, for example #ff0000 becomes #ff00.
A solution is to append a leading 0 and substring off the last 2 digits.
var rgb = $('#selector').css('backgroundColor').match(/\d+/g);
var hex = '#'+ String('0' + Number(rgb[0]).toString(16)).slice(-2) + String('0' + Number(rgb[1]).toString(16)).slice(-2) + String('0' + Number(rgb[2]).toString(16)).slice(-2);
Change database to single user mode as shown in the other answers
Sometimes, even after converting to single user mode, the only connection allowed to the database may be in use.
To close a connection even after converting to single user mode try:
select * from master.sys.sysprocesses
where spid>50 -- don't want system sessions
and dbid = DB_ID('BOSEVIKRAM')
Look at the results and see the ID of the connection to the database in question.
Then use the command below to close this connection (there should only be one since the database is now in single user mode)
KILL connection_ID
Replace connection_id with the ID in the results of the 1st query
Based off of Asaf Katz's answer, here's a typescript version:
export function union<T> (...iterables: Array<Set<T>>): Set<T> {
const set = new Set<T>()
iterables.forEach(iterable => {
iterable.forEach(item => set.add(item))
})
return set
}
I had a similar issue using an X/Y chart but then also needed to calculate the correlation function on the two sets of Data.
=IF(A1>A2,A3,#N/A)
allows the chart to be plotted but correlation of X
& Y
fails.
I solved this by
=IF(A1>A2,A3,FALSE)
The FALSE can then be removed
using conditional formatting or other tricks

One option to dynamically create and update CSS class in JavaScript:
.....
function writeStyles(styleName, cssText) {
var styleElement = document.getElementById(styleName);
if (styleElement)
document.getElementsByTagName('head')[0].removeChild(
styleElement);
styleElement = document.createElement('style');
styleElement.type = 'text/css';
styleElement.id = styleName;
styleElement.innerHTML = cssText;
document.getElementsByTagName('head')[0].appendChild(styleElement);
}
...
var cssText = '.testDIV{ height:' + height + 'px !important; }';
writeStyles('styles_js', cssText)
When calling the callback function, we could use it like below:
consumingFunction(callbackFunctionName)
Example:
// Callback function only know the action,
// but don't know what's the data.
function callbackFunction(unknown) {
console.log(unknown);
}
// This is a consuming function.
function getInfo(thenCallback) {
// When we define the function we only know the data but not
// the action. The action will be deferred until excecuting.
var info = 'I know now';
if (typeof thenCallback === 'function') {
thenCallback(info);
}
}
// Start.
getInfo(callbackFunction); // I know now
This is the Codepend with full example.
Ahahaha, here's a funny way I just came up with to do this:

where ROWNUM < 365;
where shipment_weights is any large table;
If it's always going to be an even LHS/RHS split, you can also use the partition
method that's built into strings. It returns a 3-tuple as (LHS, separator, RHS)
if the separator is found, and (original_string, '', '')
if the separator wasn't present:
>>> "2.7.0_bf4fda703454".partition('_')
('2.7.0', '_', 'bf4fda703454')
>>> "shazam".partition("_")
('shazam', '', '')
To mark a lambda async, simply prepend async
before its argument list:
// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
SQLiteUtils slu = new SQLiteUtils();
await slu.DeleteGroupAsync(groupName);
}));
Position the cursor inside the class, then press ALT + Ins and select Getters and Setters
from the contextual menu.

Please check if the setting Generate Debug Info is Yes which under Project Propeties > Configuration Properties > Linker > Debugging tab. If not, try to change it to Yes.
Those perticular pdb's ( for ntdll.dll, mscoree.dll, kernel32.dll, etc ) are for the windows API and shouldn't be needed for simple apps. However, if you cannot find pdb's for your own compiled projects, I suggest making sure the Project Properties > Configuration Properties > Debugging > Working Directory uses the value from Project Properties > Configuration Properties > General > Output Directory .

The accepted answer works well and one can also just use the
If Exists (...) Then ... End If;
syntax in Mysql procedures (if acceptable for circumstance) and it will behave as desired/expected. Here's a link to a more thorough source/description: https://dba.stackexchange.com/questions/99120/if-exists-then-update-else-insert
One problem with the solution by @SnowyR is that it does not really behave like "If Exists" in that the (Select 1 = 1 ...) subquery could return more than one row in some circumstances and so it gives an error. I don't have permissions to respond to that answer directly so I thought I'd mention it here in case it saves someone else the trouble I experienced and so others might know that it is not an equivalent solution to MSSQLServer "if exists"!
Here is a permissively-licensed C library with a variety of different FFT implementations, each of which is in its own self-contained C-file.
Come on guys, there is no need to loop, just use simple math to solve this equation system:
a*b = i;
a+b = j;
a = j/b;
a = i-b;
j/b = i-b; so:
b + j/b + i = 0
b^2 + i*b + j = 0
From here, its a quadratic equation, and it's trivial to find b (just implement the quadratic equation formula) and from there get the value for a.
EDIT:
There you go:
function finder($add,$product)
{
$inside_root = $add*$add - 4*$product;
if($inside_root >=0)
{
$b = ($add + sqrt($inside_root))/2;
$a = $add - $b;
echo "$a+$b = $add and $a*$b=$product\n";
}else
{
echo "No real solution\n";
}
}

I want to add something on @Michael Laffargue's post:
jqXHR.done()
is faster!
jqXHR.success()
have some load time in callback and sometimes can overkill script. I find that on hard way before.
UPDATE:
Using jqXHR.done()
, jqXHR.fail()
and jqXHR.always()
you can better manipulate with ajax request. Generaly you can define ajax in some variable or object and use that variable or object in any part of your code and get data faster. Good example:
/* Initialize some your AJAX function */
function call_ajax(attr){
var settings=$.extend({
call : 'users',
option : 'list'
}, attr );
return $.ajax({
type: "POST",
url: "//exapmple.com//ajax.php",
data: settings,
cache : false
});
}
/* .... Somewhere in your code ..... */
call_ajax({
/* ... */
id : 10,
option : 'edit_user'
change : {
name : 'John Doe'
}
/* ... */
}).done(function(data){
/* DO SOMETHING AWESOME */
});
In your case removing ./ should solve the issue. I had another case wherein I was using a directory from the parent directory and docker can only access files present below the directory where Dockerfile is present so if I have a directory structure /root/dir and Dockerfile /root/dir/Dockerfile

You have to self join stuff and match name and city. Then group by count.
select
s.id, s.name, s.city
from stuff s join stuff p ON (
s.name = p.city OR s.city = p.name

group by s.name having count(s.name) > 1

PS: If u didn't do the first step the scaling wont take affect. and if anyone have an explanation for this please provide. steps
in the terminal on your mac os or linux os type this code
mail -s (subject) (receiversEmailAddress) <<< "how are you?"
for an example try this
mail -s "hi" [email protected] <<< "how are you?"<br>
I ran into this scenario recently (well over 7 million rows) and eneded up using sqlcmd via powershell (after parsing raw data into SQL insert statements) in segments of 5,000 at a time (SQL can't handle 7 million lines in one lump job or even 500,000 lines for that matter unless its broken down into smaller 5K pieces. You can then run each 5K script one after the other.) as I needed to leverage the new sequence command in SQL Server 2012 Enterprise. I couldn't find a programatic way to insert seven million rows of data quickly and efficiently with said sequence command.
Secondly, one of the things to look out for when inserting a million rows or more of data in one sitting is the CPU and memory consumption (mostly memory) during the insert process. SQL will eat up memory/CPU with a job of this magnitude without releasing said processes. Needless to say if you don't have enough processing power or memory on your server you can crash it pretty easily in a short time (which I found out the hard way). If you get to the point to where your memory consumption is over 70-75% just reboot the server and the processes will be released back to normal.
I had to run a bunch of trial and error tests to see what the limits for my server was (given the limited CPU/Memory resources to work with) before I could actually have a final execution plan. I would suggest you do the same in a test environment before rolling this out into production.
The modernized way of doing this is:
curl -sL https://github.com/user-or-org/repo/archive/sha1-or-ref.tar.gz | tar xz
Replace user-or-org
, repo
, and sha1-or-ref
accordingly.
If you want a zip file instead of a tarball, specify .zip
instead of .tar.gz
suffix.
You can also retrieve the archive of a private repo, by specifying -u token:x-oauth-basic
option to curl. Replace token
with a personal access token.
First you need to compose the message. The bare minimum is composed of these two headers:
MIME-Version: 1.0
Content-Type: text/html
... and the appropriate message body:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head><title></title>
</head>
<body>
<p>Hello, world!</p>
</body>
</html>
Once you have it, you can pass the appropriate information to the mail command:
body = '...'
echo $body | mail \
-a "From: [email protected]" \
-a "MIME-Version: 1.0" \
-a "Content-Type: text/html" \
-s "This is the subject" \
[email protected]
This is an oversimplified example, since you also need to take care of charsets, encodings, maximum line length... But this is basically the idea.
Alternatively, you can write your script in Perl or PHP rather than plain shell.
A shell script is basically a text file with Unix line endings that starts with a line called shebang that tells the shell what interpreter it must pass the file to, follow some commands in the language the interpreter understands and has execution permission (in Unix that's a file attribute). E.g., let's say you save the following as hello-world
:
#!/bin/sh
echo Hello, world!
Then you assign execution permission:
chmod +x hello-world
And you can finally run it:
./hello-world
Whatever, this is kind of unrelated to the original question. You should get familiar with basic shell scripting before doing advanced tasks with it. Here you are a couple of links about bash, a popular shell:
http://www.gnu.org/software/bash/manual/html_node/index.html

You pass an undefined rAgent_IP parameter in EXEC instead of the local variable @rAgent_IP.
Still, this trigger will fail if you perform a multi-record INSERT statement.
You mean you want to add a new row and only put data in a certain column? Try the following:
var row = dataTable.NewRow();
row[myColumn].Value = "my new value";
dataTable.Add(row);
As it is a data table, though, there will always be data of some kind in every column. It just might be DBNull.Value
instead of whatever data type you imagine it would be.
The problem is with the string
"C:\Users\Eric\Desktop\beeline.txt"
Here, \U
in "C:\Users
... starts an eight-character Unicode escape, such as \U00014321
. In your code, the escape is followed by the character 's', which is invalid.
You either need to duplicate all backslashes:
"C:\\Users\\Eric\\Desktop\\beeline.txt"
Or prefix the string with r
(to produce a raw string):
r"C:\Users\Eric\Desktop\beeline.txt"

In addition to all the other good answers here, let me point out another reason to not use shift when you mean divide or multiply. I have never once seen someone introduce a bug by forgetting the relative precedence of multiplication and addition. I have seen bugs introduced when maintenance programmers forgot that "multiplying" via a shift is logically a multiplication but not syntactically of the same precedence as multiplication. x * 2 + z
and x << 1 + z
are very different!
If you're working on numbers then use arithmetic operators like + - * / %
. If you're working on arrays of bits, use bit twiddling operators like & ^ | >>
. Don't mix them; an expression that has both bit twiddling and arithmetic is a bug waiting to happen.
We can't use "PHP in between JavaScript", because PHP runs on the server and JavaScript - on the client.
However we can generate JavaScript code as well as HTML, using all PHP features, including the escaping from HTML one.

What is the best way to implement nested dictionaries in Python?
This is a bad idea, don't do it. Instead, use a regular dictionary and use dict.setdefault
where apropos, so when keys are missing under normal usage you get the expected KeyError
. If you insist on getting this behavior, here's how to shoot yourself in the foot:
Implement __missing__
on a dict
subclass to set and return a new instance.
This approach has been available (and documented) since Python 2.5, and (particularly valuable to me) it pretty prints just like a normal dict, instead of the ugly printing of an autovivified defaultdict:
class Vividict(dict):
def __missing__(self, key):
value = self[key] = type(self)() # retain local pointer to value
return value # faster to return than dict lookup
(Note self[key]
is on the left-hand side of assignment, so there's no recursion here.)
and say you have some data:
data = {('new jersey', 'mercer county', 'plumbers'): 3,
('new jersey', 'mercer county', 'programmers'): 81,
('new jersey', 'middlesex county', 'programmers'): 81,
('new jersey', 'middlesex county', 'salesmen'): 62,
('new york', 'queens county', 'plumbers'): 9,
('new york', 'queens county', 'salesmen'): 36}
Here's our usage code:
vividict = Vividict()
for (state, county, occupation), number in data.items():
vividict[state][county][occupation] = number
And now:
>>> import pprint
>>> pprint.pprint(vividict, width=40)
{'new jersey': {'mercer county': {'plumbers': 3,
'programmers': 81},
'middlesex county': {'programmers': 81,
'salesmen': 62}},
'new york': {'queens county': {'plumbers': 9,
'salesmen': 36}}}
A criticism of this type of container is that if the user misspells a key, our code could fail silently:
>>> vividict['new york']['queens counyt']
{}
And additionally now we'd have a misspelled county in our data:
>>> pprint.pprint(vividict, width=40)
{'new jersey': {'mercer county': {'plumbers': 3,
'programmers': 81},
'middlesex county': {'programmers': 81,
'salesmen': 62}},
'new york': {'queens county': {'plumbers': 9,
'salesmen': 36},
'queens counyt': {}}}
We're just providing another nested instance of our class Vividict
whenever a key is accessed but missing. (Returning the value assignment is useful because it avoids us additionally calling the getter on the dict, and unfortunately, we can't return it as it is being set.)
Note, these are the same semantics as the most upvoted answer but in half the lines of code - nosklo's implementation:
class AutoVivification(dict): """Implementation of perl's autovivification feature.""" def __getitem__(self, item): try: return dict.__getitem__(self, item) except KeyError: value = self[item] = type(self)() return value
Below is just an example of how this dict could be easily used to create a nested dict structure on the fly. This can quickly create a hierarchical tree structure as deeply as you might want to go.
import pprint
class Vividict(dict):
def __missing__(self, key):
value = self[key] = type(self)()
return value
d = Vividict()
d['foo']['bar']
d['foo']['baz']
d['fizz']['buzz']
d['primary']['secondary']['tertiary']['quaternary']
pprint.pprint(d)
Which outputs:
{'fizz': {'buzz': {}},
'foo': {'bar': {}, 'baz': {}},
'primary': {'secondary': {'tertiary': {'quaternary': {}}}}}
And as the last line shows, it pretty prints beautifully and in order for manual inspection. But if you want to visually inspect your data, implementing __missing__
to set a new instance of its class to the key and return it is a far better solution.
dict.setdefault
Although the asker thinks this isn't clean, I find it preferable to the Vividict
myself.
d = {} # or dict()
for (state, county, occupation), number in data.items():
d.setdefault(state, {}).setdefault(county, {})[occupation] = number
and now:
>>> pprint.pprint(d, width=40)
{'new jersey': {'mercer county': {'plumbers': 3,
'programmers': 81},
'middlesex county': {'programmers': 81,
'salesmen': 62}},
'new york': {'queens county': {'plumbers': 9,
'salesmen': 36}}}
A misspelling would fail noisily, and not clutter our data with bad information:
>>> d['new york']['queens counyt']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 'queens counyt'
Additionally, I think setdefault works great when used in loops and you don't know what you're going to get for keys, but repetitive usage becomes quite burdensome, and I don't think anyone would want to keep up the following:
d = dict()
d.setdefault('foo', {}).setdefault('bar', {})
d.setdefault('foo', {}).setdefault('baz', {})
d.setdefault('fizz', {}).setdefault('buzz', {})
d.setdefault('primary', {}).setdefault('secondary', {}).setdefault('tertiary', {}).setdefault('quaternary', {})
Another criticism is that setdefault requires a new instance whether it is used or not. However, Python (or at least CPython) is rather smart about handling unused and unreferenced new instances, for example, it reuses the location in memory:
>>> id({}), id({}), id({})
(523575344, 523575344, 523575344)
This is a neat looking implementation, and usage in a script that you're not inspecting the data on would be as useful as implementing __missing__
:
from collections import defaultdict
def vivdict():
return defaultdict(vivdict)
But if you need to inspect your data, the results of an auto-vivified defaultdict populated with data in the same way looks like this:
>>> d = vivdict(); d['foo']['bar']; d['foo']['baz']; d['fizz']['buzz']; d['primary']['secondary']['tertiary']['quaternary']; import pprint;
>>> pprint.pprint(d)
defaultdict(<function vivdict at 0x17B01870>, {'foo': defaultdict(<function vivdict
at 0x17B01870>, {'baz': defaultdict(<function vivdict at 0x17B01870>, {}), 'bar':
defaultdict(<function vivdict at 0x17B01870>, {})}), 'primary': defaultdict(<function
vivdict at 0x17B01870>, {'secondary': defaultdict(<function vivdict at 0x17B01870>,
{'tertiary': defaultdict(<function vivdict at 0x17B01870>, {'quaternary': defaultdict(
<function vivdict at 0x17B01870>, {})})})}), 'fizz': defaultdict(<function vivdict at
0x17B01870>, {'buzz': defaultdict(<function vivdict at 0x17B01870>, {})})})
This output is quite inelegant, and the results are quite unreadable. The solution typically given is to recursively convert back to a dict for manual inspection. This non-trivial solution is left as an exercise for the reader.
Finally, let's look at performance. I'm subtracting the costs of instantiation.
>>> import timeit
>>> min(timeit.repeat(lambda: {}.setdefault('foo', {}))) - min(timeit.repeat(lambda: {}))
0.13612580299377441
>>> min(timeit.repeat(lambda: vivdict()['foo'])) - min(timeit.repeat(lambda: vivdict()))
0.2936999797821045
>>> min(timeit.repeat(lambda: Vividict()['foo'])) - min(timeit.repeat(lambda: Vividict()))
0.5354437828063965
>>> min(timeit.repeat(lambda: AutoVivification()['foo'])) - min(timeit.repeat(lambda: AutoVivification()))
2.138362169265747
Based on performance, dict.setdefault
works the best. I'd highly recommend it for production code, in cases where you care about execution speed.
If you need this for interactive use (in an IPython notebook, perhaps) then performance doesn't really matter - in which case, I'd go with Vividict for readability of the output. Compared to the AutoVivification object (which uses __getitem__
instead of __missing__
, which was made for this purpose) it is far superior.
Implementing __missing__
on a subclassed dict
to set and return a new instance is slightly more difficult than alternatives but has the benefits of
and because it is less complicated and more performant than modifying __getitem__
, it should be preferred to that method.
Nevertheless, it has drawbacks:
Thus I personally prefer setdefault
to the other solutions, and have in every situation where I have needed this sort of behavior.
You can use the functions in Python's built-in signal module to set up signal handlers in python. Specifically the signal.signal(signalnum, handler)
function is used to register the handler
function for signal signalnum
.
A variation of the top answer that handles null
:
public static <T, K> Predicate<T> distinctBy(final Function<? super T, K> getKey) {
val seen = ConcurrentHashMap.<Optional<K>>newKeySet();
return obj -> seen.add(Optional.ofNullable(getKey.apply(obj)));
}
In my tests:
assertEquals(
asList("a", "bb"),
Stream.of("a", "b", "bb", "aa").filter(distinctBy(String::length)).collect(toList()));
assertEquals(
asList(5, null, 2, 3),
Stream.of(5, null, 2, null, 3, 3, 2).filter(distinctBy(x -> x)).collect(toList()));
val maps = asList(
hashMapWith(0, 2),
hashMapWith(1, 2),
hashMapWith(2, null),
hashMapWith(3, 1),
hashMapWith(4, null),
hashMapWith(5, 2));
assertEquals(
asList(0, 2, 3),
maps.stream()
.filter(distinctBy(m -> m.get("val")))
.map(m -> m.get("i"))
.collect(toList()));
Selects a subset of the array to return based on the specified condition. Returns an array with only those elements that match the condition. The returned elements are in the original order.
db.test.aggregate([
{$match: {"list.a": {$gt:3}}}, // <-- match only the document which have a matching element
{$project: {
list: {$filter: {
input: "$list",
as: "list",
cond: {$gt: ["$$list.a", 3]} //<-- filter sub-array based on condition
}}
}}
]);
all answers are great
, and it seems that no
more answer is needed
but I just wonted to point out something about &&
operator called dependent condition
In expressions using operator &&, a condition—we’ll call this the dependent condition
—may require another condition to be true for the evaluation of the dependent condition to be meaningful.
In this case, the dependent condition should be placed after the && operator to prevent errors.
Consider the expression (i != 0) && (10 / i == 2)
. The dependent condition (10 / i == 2)
must appear after
the &&
operator to prevent the possibility of division by zero.
another example (myObject != null) && (myObject.getValue() == somevaluse)
and another thing: &&
and ||
are called short-circuit evaluation because the second argument is executed or evaluated only if
the first
argument does not suffice
to determine
the value
of the expression

I had same problem. it happen because javascript
expect json
data type in returning data. but if you use echo or print in your php this situation occur. if you use echo
function in php
to return data, Simply remove dataType : "json"

This is a little late in the game as several others have already answered nicely, but I'll share how I might implement it.
This hinges on the fact that the Firebase REST API offers a shallow=true
parameter.
Assume you have a post
object and each one can have a number of comments
:
{
"posts": {
"$postKey": {
"comments": {
...
}
}
}
}
You obviously don't want to fetch all of the comments, just the number of comments.
Assuming you have the key for a post, you can send a GET
request to
https://yourapp.firebaseio.com/posts/[the post key]/comments?shallow=true
.
This will return an object of key-value pairs, where each key is the key of a comment and its value is true
:
{
"comment1key": true,
"comment2key": true,
...,
"comment9999key": true
}
The size of this response is much smaller than requesting the equivalent data, and now you can calculate the number of keys in the response to find your value (e.g. commentCount = Object.keys(result).length
).
This may not completely solve your problem, as you are still calculating the number of keys returned, and you can't necessarily subscribe to the value as it changes, but it does greatly reduce the size of the returned data without requiring any changes to your schema.

This question is a fairly difficult one. There is no real software limitation on the number of active connections a machine can have, though some OS's are more limited than others. The problem becomes one of resources. For example, let's say a single machine wants to support 64,000 simultaneous connections. If the server uses 1MB of RAM per connection, it would need 64GB of RAM. If each client needs to read a file, the disk or storage array access load becomes much larger than those devices can handle. If a server needs to fork one process per connection then the OS will spend the majority of its time context switching or starving processes for CPU time.

The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
Once it is in the centre, I give to the image,
// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;
// For Horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;
This makes the image get the effect of Object-fit:cover.

This answer is based on removing and adding views dynamically
To disable scrolling:
View child = scoll.getChildAt(0);// since scrollView can only have one direct child
ViewGroup parent = (ViewGroup) scroll.getParent();
scroll.removeView(child); // remove child from scrollview
parent.addView(child,parent.indexOfChild(scroll));// add scroll child at the position of scrollview
parent.removeView(scroll);// remove scrollView from parent
To enable ScrollView just reverse the process

Maybe another question is, "what are you going to do with those indices once you get them?" If you are going to use them to create another list, then in Python, they are an unnecessary middle step. If you want all the values that match a given condition, just use the builtin filter:
matchingVals = filter(lambda x : x>2, a)
Or write your own list comprhension:
matchingVals = [x for x in a if x > 2]
If you want to remove them from the list, then the Pythonic way is not to necessarily remove from the list, but write a list comprehension as if you were creating a new list, and assigning back in-place using the listvar[:]
on the left-hand-side:
a[:] = [x for x in a if x <= 2]
Matlab supplies find
because its array-centric model works by selecting items using their array indices. You can do this in Python, certainly, but the more Pythonic way is using iterators and generators, as already mentioned by @EliBendersky.
What you're talking about is becoming a payment service provider. I have been there and done that. It was a lot easier about 10 years ago than it is now, but if you have a phenomenal amount of time, money and patience available, it is still possible.
You will need to contact an acquiring bank. You didnt say what region of the world you are in, but by this I dont mean a local bank branch. Each major bank will generally have a separate card acquiring arm. So here in the UK we have (eg) Natwest bank, which uses Streamline (or Worldpay) as its acquiring arm. In total even though we have scores of major banks, they all end up using one of five or so card acquirers.
Happily, all UK card acquirers use a standard protocol for communication of authorisation requests, and end of day settlement. You will find minor quirks where some acquiring banks support some features and have slightly different syntax, but the differences are fairly minor. The UK standards are published by the Association for Payment Clearing Services (APACS) (which is now known as the UKPA). The standards are still commonly referred to as APACS 30 (authorization) and APACS 29 (settlement), but are now formally known as APACS 70 (books 1 through 7).
Although the APACS standard is widely supported across the UK (Amex and Discover accept messages in this format too) it is not used in other countries - each country has it's own - for example: Carte Bancaire in France, CartaSi in Italy, Sistema 4B in Spain, Dankort in Denmark etc. An effort is under way to unify the protocols across Europe - see EPAS.org
Communicating with the acquiring bank can be done a number of ways. Again though, it will depend on your region. In the UK (and most of Europe) we have one communications gateway that provides connectivity to all the major acquirers, they are called TNS and there are dozens of ways of communicating through them to the acquiring bank, from dialup 9600 baud modems, ISDN, HTTPS, VPN or dedicated line. Ultimately the authorisation request will be converted to X25 protocol, which is the protocol used by these acquiring banks when communicating with each other.
In summary then: it all depends on your region.
Once you are registered and accredited you'll then be able to accept customers and set up merchant accounts on behalf of the bank/s you're accredited against (bearing in mind that each acquirer will generally support multiple banks). Rinse and repeat with other acquirers as you see necessary.
Beyond that you have lots of other issues, mainly dealing with PCI-DSS. Thats a whole other topic and there are already some q&a's on this site regarding that. Like I say, its a phenomenal undertaking - most likely a multi-year project even for a reasonably sized team, but its certainly possible.

You should implement a Custom List View, such that you define a Layout once and draw it for every row in the list view.
library(lubridate)
if your date format is like this '04/24/2017 05:35:00'then change it like below
prods.all$Date2<-gsub("/","-",prods.all$Date2)
then change the date format
parse_date_time(prods.all$Date2, orders="mdy hms")
We can use setTag()
and getTag()
to set and get custom objects as per our requirement. The setTag()
method takes an argument of type Object
, and getTag()
returns an Object
.
For example,
Person p = new Person();
p.setName("Ramkailash");
p.setId(2000001);
button1.setTag(p);
Use the df command:
df -h
The only way to control the size of stack within process is start a new Thread

The thread is old, but maybe someone is still interested. The shortest form I found is further improvement on the example from ?lex and bmargulies. The execution tag will look like:
<execution>
<id>TheNameOfTheRelevantExecution</id>
<phase/>
</execution>
2 points I want to highlight:
After posting found it is already in stackoverflow: In a Maven multi-module project, how can I disable a plugin in one child?
Use COALESCE. Instead of your_column
use COALESCE(your_column, '')
. This will return the empty string instead of NULL.
Simple Way :
ProgressDialog pDialog = new ProgressDialog(MainActivity.this); //Your Activity.this
pDialog.setMessage("Loading...!");
pDialog.setCancelable(false);
pDialog.show();
Try this:
echo $array[0]->id;
PATH
is an environment variable, and can be displayed with the echo command:
echo $PATH
It's a list of paths separated by the colon character ':
'
The which
command tells you which file gets executed when you run a command:
which lshw
sometimes what you get is a path to a symlink; if you want to trace that link to where the actual executable lives, you can use readlink
and feed it the output of which
:
readlink -f $(which lshw)
The -f
parameter instructs readlink
to keep following the symlink recursively.
Here's an example from my machine:
$ which firefox
/usr/bin/firefox
$ readlink -f $(which firefox)
/usr/lib/firefox-3.6.3/firefox.sh
for entry in "/home/loc/etc/"/*
do
if [ -s /home/loc/etc/$entry ]
then
echo "$entry File is available"
else
echo "$entry File is not available"
fi
done
Hope it helps
Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.
You should read Working with Auto Layout Programmatically and Visual Format Language.
You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.
You can use the rather sensibly named xpath function called concat here
<a>
<xsl:attribute name="href">
<xsl:value-of select="concat('myText:', /*/properties/property[@name='report']/@value)" />
</xsl:attribute>
</a>
Of course, it doesn't have to be text here, it can be another xpath expression to select an element or attribute. And you can have any number of arguments in the concat expression.
Do note, you can make use of Attribute Value Templates (represented by the curly braces) here to simplify your expression
<a href="{concat('myText:', /*/properties/property[@name='report']/@value)}"></a>
Update:
Planned in the scope of 3.7 release
https://github.com/microsoft/TypeScript/issues/33352
You can try to write a custom function like that.
The main advantage of the approach is a type-checking and partial intellisense.
export function nullSafe<T,
K0 extends keyof T,
K1 extends keyof T[K0],
K2 extends keyof T[K0][K1],
K3 extends keyof T[K0][K1][K2],
K4 extends keyof T[K0][K1][K2][K3],
K5 extends keyof T[K0][K1][K2][K3][K4]>
(obj: T, k0: K0, k1?: K1, k2?: K2, k3?: K3, k4?: K4, k5?: K5) {
let result: any = obj;
const keysCount = arguments.length - 1;
for (var i = 1; i <= keysCount; i++) {
if (result === null || result === undefined) return result;
result = result[arguments[i]];
}
return result;
}
And usage (supports up to 5 parameters and can be extended):
nullSafe(a, 'b', 'c');
Example on playground.
Your compiler just tried to compile the file named foo.cc
. Upon hitting line number line
, the compiler finds:
#include "bar"
or
#include <bar>
The compiler then tries to find that file. For this, it uses a set of directories to look into, but within this set, there is no file bar
. For an explanation of the difference between the versions of the include statement look here.
g++
has an option -I
. It lets you add include search paths to the command line. Imagine that your file bar
is in a folder named frobnicate
, relative to foo.cc
(assume you are compiling from the directory where foo.cc
is located):
g++ -Ifrobnicate foo.cc
You can add more include-paths; each you give is relative to the current directory. Microsoft's compiler has a correlating option /I
that works in the same way, or in Visual Studio, the folders can be set in the Property Pages of the Project, under Configuration Properties->C/C++->General->Additional Include Directories.
Now imagine you have multiple version of bar
in different folders, given:
// A/bar
#include<string>
std::string which() { return "A/bar"; }
// B/bar
#include<string>
std::string which() { return "B/bar"; }
// C/bar
#include<string>
std::string which() { return "C/bar"; }
// foo.cc
#include "bar"
#include <iostream>
int main () {
std::cout << which() << std::endl;
}
The priority with #include "bar"
is leftmost:
$ g++ -IA -IB -IC foo.cc
$ ./a.out
A/bar
As you see, when the compiler started looking through A/
, B/
and C/
, it stopped at the first or leftmost hit.
This is true of both forms, include <>
and incude ""
.
#include <bar>
and #include "bar"
Usually, the #include <xxx>
makes it look into system folders first, the #include "xxx"
makes it look into the current or custom folders first.
E.g.:
Imagine you have the following files in your project folder:
list
main.cc
with main.cc
:
#include "list"
....
For this, your compiler will #include
the file list
in your project folder, because it currently compiles main.cc
and there is that file list
in the current folder.
But with main.cc
:
#include <list>
....
and then g++ main.cc
, your compiler will look into the system folders first, and because <list>
is a standard header, it will #include
the file named list
that comes with your C++ platform as part of the standard library.
This is all a bit simplified, but should give you the basic idea.
<>
/""
-priorities and -I
According to the gcc-documentation, the priority for include <>
is, on a "normal Unix system", as follows:
/usr/local/include
libdir/gcc/target/version/include
/usr/target/include
/usr/include
For C++ programs, it will also look in /usr/include/c++/version, first. In the above, target is the canonical name of the system GCC was configured to compile code for; [...].
The documentation also states:
You can add to this list with the -Idir command line option. All the directories named by -I are searched, in left-to-right order, before the default directories. The only exception is when dir is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged.
To continue our #include<list> / #include"list"
example (same code):
g++ -I. main.cc
and
#include<list>
int main () { std::list<int> l; }
and indeed, the -I.
prioritizes the folder .
over the system includes and we get a compiler error.
When you say "in you package folder," do you mean your local app files? If so you can get a list of them using the Context.fileList() method. Just iterate through and look for your file. That's assuming you saved the original file with Context.openFileOutput().
Sample code (in an Activity):
public void onCreate(...) {
super.onCreate(...);
String[] files = fileList();
for (String file : files) {
if (file.equals(myFileName)) {
//file exits
}
}
}
Just as Daniel said "Git and TFVC are the two source control options in TFS
". Fortunately both are supported for now in VS Code.
You need to install the Azure Repos Extension for Visual Studio Code. The process of installing is pretty straight forward.
Add the following lines to your user settings
If you have VS 2015 installed on your machine, your path to Team Foundation tool (tf.exe) may look like this:
{ "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\tf.exe", "tfvc.restrictWorkspace": true }
Or for VS 2017:
{ "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\CommonExtensions\\Microsoft\\TeamFoundation\\Team Explorer\\tf.exe", "tfvc.restrictWorkspace": true }
Open a local folder (repository), From View -> Command Pallette ..., type team signin
Provide user name --> Enter --> Provide password to connect to TFS.
Please refer to below links for more details:
Note that Server Workspaces are not supported:
"TFVC support is limited to Local workspaces":
SELECT specific_name FROM `information_schema`.`ROUTINES` WHERE routine_schema='database_name'
Another variant:
List<MyType> items = new List<MyType>();
items.AddRange(myDico.values);
copy (anysql query datawanttoexport) to 'fileablsoutepathwihname' delimiter ',' csv header;
Using this u can export data also.
The top answer worked fine but I suggest saving your JSON data into a variable before posting it is a little bit cleaner when sending a long form or dealing with large data in general.
var Data = {_x000D_
"name":"jonsa",_x000D_
"e-mail":"[email protected]",_x000D_
"phone":1223456789_x000D_
};_x000D_
_x000D_
_x000D_
$.ajax({_x000D_
type: 'POST',_x000D_
url: '/form/',_x000D_
data: Data,_x000D_
success: function(data) { alert('data: ' + data); },_x000D_
contentType: "application/json",_x000D_
dataType: 'json'_x000D_

Simple function for splitting a vector by simply using indexes - no need to over complicate this
vsplit <- function(v, n) {
l = length(v)
r = l/n
return(lapply(1:n, function(i) {
s = max(1, round(r*(i-1))+1)
e = min(l, round(r*i))
return(v[s:e])
}))
}
I'm not entirely sure what visual end result you're after, but here's an easy way to blur an image's edge: place a div with the image inside another div with the blurred image.
Working example here: http://jsfiddle.net/ZY5hn/1/
HTML:
<div class="placeholder">
<!-- blurred background image for blurred edge -->
<div class="bg-image-blur"></div>
<!-- same image, no blur -->
<div class="bg-image"></div>
<!-- content -->
<div class="content">Blurred Image Edges</div>
</div>
CSS:
.placeholder {
margin-right: auto;
margin-left:auto;
margin-top: 20px;
width: 200px;
height: 200px;
position: relative;
/* this is the only relevant part for the example */
}
/* both DIVs have the same image */
.bg-image-blur, .bg-image {
background-image: url('http://lorempixel.com/200/200/city/9');
position:absolute;
top:0;
left:0;
width: 100%;
height:100%;
}
/* blur the background, to make blurred edges that overflow the unblurred image that is on top */
.bg-image-blur {
-webkit-filter: blur(20px);
-moz-filter: blur(20px);
-o-filter: blur(20px);
-ms-filter: blur(20px);
filter: blur(20px);
}
/* I added this DIV in case you need to place content inside */
.content {
position: absolute;
top:0;
left:0;
width: 100%;
height: 100%;
color: #fff;
text-shadow: 0 0 3px #000;
text-align: center;
font-size: 30px;
}
Notice the blurred effect is using the image, so it changes with the image color.
I hope this helps.
You can't use same id for multiple elements in a document. Keep the ids different and name same for the elements.
<input type="text" id="task1" name="task" />
<input type="text" id="task2" name="task" />
<input type="text" id="task3" name="task" />
<input type="text" id="task4" name="task" />
<input type="text" id="task5" name="task" />
var newArray = new Array();
$("input:text[name=task]").each(function(){
newArray.push($(this));
});
If you want to change display name only then you can directly change from property file(plist) of app.
You can add a new row with the following key : bundle display name
Here is an example for this
When you use this the app name which you have given with this key will be display.
So you can do this simply.
You can use the following class to pinpoint transitivity bugs in your Comparators:
/**
* @author Gili Tzabari
*/
public final class Comparators
{
/**
* Verify that a comparator is transitive.
*
* @param <T> the type being compared
* @param comparator the comparator to test
* @param elements the elements to test against
* @throws AssertionError if the comparator is not transitive
*/
public static <T> void verifyTransitivity(Comparator<T> comparator, Collection<T> elements)
{
for (T first: elements)
{
for (T second: elements)
{
int result1 = comparator.compare(first, second);
int result2 = comparator.compare(second, first);
if (result1 != -result2)
{
// Uncomment the following line to step through the failed case
//comparator.compare(first, second);
throw new AssertionError("compare(" + first + ", " + second + ") == " + result1 +
" but swapping the parameters returns " + result2);
}
}
}
for (T first: elements)
{
for (T second: elements)
{
int firstGreaterThanSecond = comparator.compare(first, second);
if (firstGreaterThanSecond <= 0)
continue;
for (T third: elements)
{
int secondGreaterThanThird = comparator.compare(second, third);
if (secondGreaterThanThird <= 0)
continue;
int firstGreaterThanThird = comparator.compare(first, third);
if (firstGreaterThanThird <= 0)
{
// Uncomment the following line to step through the failed case
//comparator.compare(first, third);
throw new AssertionError("compare(" + first + ", " + second + ") > 0, " +
"compare(" + second + ", " + third + ") > 0, but compare(" + first + ", " + third + ") == " +
firstGreaterThanThird);
}
}
}
}
}
/**
* Prevent construction.
*/
private Comparators()
{
}
}
Simply invoke Comparators.verifyTransitivity(myComparator, myCollection)
in front of the code that fails.

From Microsoft documentation:
PAGEIOLATCH_SH
Occurs when a task is waiting on a latch for a buffer that is in an
I/O
request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem.
In practice, this almost always happens due to large scans over big tables. It almost never happens in queries that use indexes efficiently.
If your query is like this:
Select * from <table> where <col1> = <value> order by <PrimaryKey>
, check that you have a composite index on (col1, col_primary_key)
.
If you don't have one, then you'll need either a full INDEX SCAN
if the PRIMARY KEY
is chosen, or a SORT
if an index on col1
is chosen.
Both of them are very disk I/O
consuming operations on large tables.
I recommand the following article : Hit Region Detection For HTML5 Canvas And How To Listen To Click Events On Canvas Shapes which goes through various situations.
However, it does not cover the addHitRegion
API, which must be the best way (using math functions and/or comparisons is quite error prone). This approach is detailed on developer.mozilla
Use the following script after appending your select.
$('#state').select2();
Don't use destroy
.
Use this command:
sudo chown -R $USER ~/.composer/
I tried to resolve with the suggested answer and still ran into some issues...
This was a solution to my problem:
ARG APP_EXE="AppName.exe"
ENV _EXE=${APP_EXE}
# Build a shell script because the ENTRYPOINT command doesn't like using ENV
RUN echo "#!/bin/bash \n mono ${_EXE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
# Run the generated shell script.
ENTRYPOINT ["./entrypoint.sh"]
Specifically targeting your problem:
RUN echo "#!/bin/bash \n ./greeting --message ${ADDRESSEE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]
This is definitely a bug.Laravel offers predefined code in routes/api.php
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
which is unabled to be processed by:
php artisan route:cache
This definitely should be fixed by Laravel team.(check the link),
simply if you want to fix it you should replace routes\api.php code with some thing like :
Route::middleware('auth:api')->get('/user', 'UserController@AuthRouteAPI');
and in UserController put this method:
public function AuthRouteAPI(Request $request){
return $request->user();
}
Here are some dplyr
options:
# sample data
df <- data.frame(a = c('1', NA, '3', NA), b = c('a', 'b', 'c', NA), c = c('e', 'f', 'g', NA))
library(dplyr)
# remove rows where all values are NA:
df %>% filter_all(any_vars(!is.na(.)))
df %>% filter_all(any_vars(complete.cases(.)))
# remove rows where only some values are NA:
df %>% filter_all(all_vars(!is.na(.)))
df %>% filter_all(all_vars(complete.cases(.)))
# or more succinctly:
df %>% filter(complete.cases(.))
df %>% na.omit
# dplyr and tidyr:
library(tidyr)
df %>% drop_na
Simply type:
list(my_set)
This will turn a set in the form {'1','2'} into a list in the form ['1','2'].
In theory, there's nothing preventing you from sending a request body in a GET
request. The HTTP protocol allows it, but have no defined semantics, so it's up to you to document what exactly is going to happen when a client sends a GET
payload. For instance, you have to define if parameters in a JSON body are equivalent to querystring parameters or something else entirely.
However, since there are no clearly defined semantics, you have no guarantee that implementations between your application and the client will respect it. A server or proxy might reject the whole request, or ignore the body, or anything else. The REST way to deal with broken implementations is to circumvent it in a way that's decoupled from your application, so I'd say you have two options that can be considered best practices.
The simple option is to use POST
instead of GET
as recommended by other answers. Since POST
is not standardized by HTTP, you'll have to document how exactly that's supposed to work.
Another option, which I prefer, is to implement your application assuming the GET
payload is never tampered with. Then, in case something has a broken implementation, you allow clients to override the HTTP method with the X-HTTP-Method-Override
, which is a popular convention for clients to emulate HTTP methods with POST
. So, if a client has a broken implementation, it can write the GET
request as a POST
, sending the X-HTTP-Method-Override: GET
method, and you can have a middleware that's decoupled from your application implementation and rewrites the method accordingly. This is the best option if you're a purist.
const http = require('http');
const url = require('url');
http.createServer((req,res)=>{
const parseObj = url.parse(req.url,true);
const users = [{id:1,name:'soura'},{id:2,name:'soumya'}]
if(parseObj.pathname == '/user-details' && req.method == "GET") {
let Id = parseObj.query.id;
let user_details = {};
users.forEach((data,index)=>{
if(data.id == Id){
user_details = data;
}
})
res.writeHead(200,{'x-auth-token':'Auth Token'})
res.write(JSON.stringify(user_details)) // Json to String Convert
res.end();
}
}).listen(8000);
I have used the above code in my existing project.
If you are using the Support Library provided DrawerLayout as suggested in the Creating a navigation drawer training, you can use the newly added android.support.v7.app.ActionBarDrawerToggle (note: different from the now deprecated android.support.v4.app.ActionBarDrawerToggle):
shows a Hamburger icon when drawer is closed and an arrow when drawer is open. It animates between these two states as the drawer opens.
While the training hasn't been updated to take the deprecation/new class into account, you should be able to use it almost exactly the same code - the only difference in implementing it is the constructor.
Look at the source code in Modernizer, this section:
// Change `no-js` to `js` (independently of the `enableClasses` option)
// Handle classPrefix on this too
if (Modernizr._config.enableJSClass) {
var reJS = new RegExp('(^|\\s)' + classPrefix + 'no-js(\\s|$)');
className = className.replace(reJS, '$1' + classPrefix + 'js$2');
}
So basically it search for classPrefix + no-js
class and replace it with classPrefix + js
.
And the use of that, is styling differently if JavaScript not running in the browser.
The simulator is just an application, and as such you can run it like any other application.
To run the simulator straight from terminal prepend these locations with the open
command
Xcode 7.x, 8.x, and 9.x
In Xcode 7.x, the iPhone Simulator has moved again: /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app
.
Xcode 6.x
In Xcode 6.x, the iPhone Simulator has moved yet again, and now resides here: /Applications/Xcode.app/Contents/Developer/Applications/iOS Simulator.app
.
Xcode 4.x, 5.x
In Xcode 4.x (through 4.5 on Mountain Lion) and Xcode 5.0.x on Mavericks, it lives here: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/
In my version of Xcode (4.5.2), I find it quite convenient to use the Open Developer Tool
menu from either the dock icon or the Xcode menu:
Xcode 3.x
In Xcode 3.x, it lives here:
/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app
In some future version of Xcode, it will probably move again, it's a squirrelly little app.
In the 5.1 release of react-router there is a hook called useLocation, which returns the current location object. This might useful any time you need to know the current URL.
import { useLocation } from 'react-router-dom'
function HeaderView() {
const location = useLocation();
console.log(location.pathname);
return <span>Path : {location.pathname}</span>
}
As you have to use WITH (NOLOCK) for each table it might be annoying to write it in every FROM or JOIN clause. However it has a reason why it is called a "dirty" read. So you really should know when you do one, and not set it as default for the session scope. Why?
Forgetting a WITH (NOLOCK) might not affect your program in a very dramatic way, however doing a dirty read where you do not want one can make the difference in certain circumstances.
So use WITH (NOLOCK) if the current data selected is allowed to be incorrect, as it might be rolled back later. This is mostly used when you want to increase performance, and the requirements on your application context allow it to take the risk that inconsistent data is being displayed. However you or someone in charge has to weigh up pros and cons of the decision of using WITH (NOLOCK).
I also found a workaround which seems to work fine with no warnings:
<resources>
<item name="the_name" type="dimen">255%</item>
<item name="another_name" type="dimen">15%</item>
</resources>
Then:
// theName = 2.55f
float theName = getResources().getFraction(R.dimen.the_name, 1, 1);
// anotherName = 0.15f
float anotherName = getResources().getFraction(R.dimen.another_name, 1, 1);
Warning : it only works when you use the dimen from Java code not from xml
You can put them in the Application:
Application["GlobalVar"] = 1234;
They are only global within the current IIS / Virtual applicition. This means, on a webfarm they are local to the server, and within the virtual directory that is the root of the application.
If you're certain that you have installed ssh, then it's possible that ssh
and/or sshd
has been terminated or the server service hasn't been started. To check whether these processes are running use:
//this tells you whether your ssh instance is active/inactive
sudo service ssh status
OR
//this list all running processes whose names contain the string "ssh"
sudo ps -A | grep ssh
It's likely that ssh
would be active and running but sshd
would not.
To enable them:
sudo service ssh start
NB; - some systems have a restart option but mine didn't

No one has explicitly mentioned that weightSum
is a particular XML attribute for LinearLayout
.
I believe this would be helpful to anyone who was confused at first as I was, looking for weightSum
in the ConstraintLayout
documentation.
You can use Object for storing any type of value for e.g. int, float, String, class objects, or any other java objects, since it is the root of all the class. For e.g.
Declaring a class
class Person {
public int personId;
public String personName;
public int getPersonId() {

}
public void setPersonId(int personId) {
this.personId = personId;
}
public String getPersonName() {
return personName;
}
public void setPersonName(String personName) {
this.personName = personName;
}}
main function code, which creates the new person object, int, float, and string type, and then is added to the List, and iterated using for loop. Each object is identified, and then the value is printed.
Person p = new Person();
p.setPersonId(1);
p.setPersonName("Tom");
List<Object> lstObject = new ArrayList<Object>();
lstObject.add(1232);
lstObject.add("String");
lstObject.add(122.212f);
lstObject.add(p);
for (Object obj : lstObject) {
if (obj.getClass() == String.class) {
System.out.println("I found a string :- " + obj);
}
if (obj.getClass() == Integer.class) {
System.out.println("I found an int :- " + obj);
}
if (obj.getClass() == Float.class) {
System.out.println("I found a float :- " + obj);
}
if (obj.getClass() == Person.class) {
Person person = (Person) obj;
System.out.println("I found a person object");
System.out.println("Person Id :- " + person.getPersonId());
System.out.println("Person Name :- " + person.getPersonName());
}
}

This is working for me using this Bootsrap Datetimepiker, it returns the value as it is shown in the datepicker input, e.g. 2019-04-11

//console.log(myDate);
//alert(myDate);
});
First make sure that you have a SSH key or generate one at: https://help.github.com/articles/generating-ssh-keys/
Once you have your key, you have to add it to your github account at: https://github.com/settings/ssh
For Windows users it's useful to run git bash as an administrator.
Now the cloning should work for private repositories (repo), without having to put your username and password.
Don't use height property in input field.
Example:
.heighttext{
display:inline-block;
padding:15px 10px;
line-height:140%;
}
Always use padding and line-height css property. Its work perfect for all mobile device and all browser.
How about (works also for 0 and negatives):
int digits( int x ) {
return ( (bool) x * (int) log10( abs( x ) ) + 1 );
}
Didn't see any answers correctly using DATE_ADD
or DATE_SUB
:
Subtract 1 day from NOW()
...WHERE DATE_FIELD >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Add 1 day from NOW()
...WHERE DATE_FIELD >= DATE_ADD(NOW(), INTERVAL 1 DAY)
can also appear if:
struct foo { int x, int y, int z }foo;
foo.x=12
instead of
struct foo { int x; int y; int z; }foo;
foo.x=12
Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.
What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?
You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.
I just followed a method that we would usually follow in java script. To convert object to string and then check whether they are null.
var obj = new Object();
var objStr = obj.ToString();
if (!string.IsNullOrEmpty(objStr)){
// code as per your needs
}
If you are using the Google Chrome driver, you can use this very simple code (it worked for me):
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome('chromedriver2_win32/chromedriver.exe', options=chrome_options)
driver.get('https://www.anywebsite.com')
Change the = to : to
fix the error.
var makeRequest = function(message) {<br>
var options = {<br>
host: 'localhost',<br>
port : 8080,<br>
path : '/',<br>
method: 'POST'<br>
}
How can I send my $scope object from one controller to another using .$emit and .$on methods?
You can send any object you want within the hierarchy of your app, including $scope.
Here is a quick idea about how broadcast and emit work.
Notice the nodes below; all nested within node 3. You use broadcast and emit when you have this scenario.
Note: The number of each node in this example is arbitrary; it could easily be the number one; the number two; or even the number 1,348. Each number is just an identifier for this example. The point of this example is to show nesting of Angular controllers/directives.

Check out this tree. How do you answer the following questions?
Note: There are other ways to answer these questions, but here we'll discuss broadcast and emit. Also, when reading below text assume each number has it's own file (directive, controller) e.x. one.js, two.js, three.js.
How does node 1 speak to node 3?
In file one.js
scope.$emit('messageOne', someValue(s));
In file three.js - the uppermost node to all children nodes needed to communicate.
scope.$on('messageOne', someValue(s));
How does node 2 speak to node 3?
In file two.js
scope.$emit('messageTwo', someValue(s));
In file three.js - the uppermost node to all children nodes needed to communicate.
scope.$on('messageTwo', someValue(s));
How does node 3 speak to node 1 and/or node 2?
In file three.js - the uppermost node to all children nodes needed to communicate.
scope.$broadcast('messageThree', someValue(s));
In file one.js && two.js whichever file you want to catch the message or both.
scope.$on('messageThree', someValue(s));
How does node 2 speak to node 1?
In file two.js
scope.$emit('messageTwo', someValue(s));
In file three.js - the uppermost node to all children nodes needed to communicate.
scope.$on('messageTwo', function( event, data ){
scope.$broadcast( 'messageTwo', data );
});
In file one.js
scope.$on('messageTwo', someValue(s));
HOWEVER
When you have all these nested child nodes trying to communicate like this, you will quickly see many $on's, $broadcast's, and $emit's.
Here is what I like to do.
In the uppermost PARENT NODE ( 3 in this case... ), which may be your parent controller...
So, in file three.js
scope.$on('pushChangesToAllNodes', function( event, message ){
scope.$broadcast( message.name, message.data );
});
Now in any of the child nodes you only need to $emit the message or catch it using $on.
NOTE: It is normally quite easy to cross talk in one nested path without using $emit, $broadcast, or $on, which means most use cases are for when you are trying to get node 1 to communicate with node 2 or vice versa.
How does node 2 speak to node 1?
In file two.js
scope.$emit('pushChangesToAllNodes', sendNewChanges());
function sendNewChanges(){ // for some event.
return { name: 'talkToOne', data: [1,2,3] };
}
In file three.js - the uppermost node to all children nodes needed to communicate.
We already handled this one remember?
In file one.js
scope.$on('talkToOne', function( event, arrayOfNumbers ){
arrayOfNumbers.forEach(function(number){
console.log(number);
});
});
You will still need to use $on with each specific value you want to catch, but now you can create whatever you like in any of the nodes without having to worry about how to get the message across the parent node gap as we catch and broadcast the generic pushChangesToAllNodes.
Hope this helps...
