I'm going to guess you aren't getting errors or you would've mentioned them. If that's the case, try removing the href
attribute value so the page doesn't navigate away before your code is executed. In Angular it's perfectly acceptable to leave href
attributes blank.
<a href="" data-router="article" ng-click="changeListName('metro')">
Also I don't know what data-router
is doing but if you still aren't getting the proper result, that could be why.
To get selected item, you have to use SELECTEDITEM property of comboBox. And since this is an Object, if you wanna assign it to a string, you have to convert it to string, by using ToString() method:
string myItem = comboBox1.SelectedItem.ToString(); //this does the trick
substring
(MDN) takes parameters as (from, to)
.
substr
(MDN) takes parameters as (from, length)
.
Update: MDN considers substr
legacy.
alert("abc".substr(1,2)); // returns "bc"
alert("abc".substring(1,2)); // returns "b"
You can remember substring
(with an i) takes indices, as does yet another string extraction method, slice (with an i).
When starting from 0 you can use either method.
I had the same issues and i had dialogComponent in EntryComponents and it still did not work. this is how I was able to solve the problem. the link is here to a previously answered post:
what you are searching for is the Export-Csv file.csv
try using Get-Help Export-Csv to see whats possible
also Out-File -FilePath "file.csv"
will work
Changing to Varchar(1200) from Varchar(200) should cause you no issue as it is only a metadata change and as SQL server 2008 truncates excesive blank spaces you should see no performance differences either so in short there should be no issues with making the change.
Notwithstanding the other answers recommending List<T>
, you'll want to use arrays when handling:
By process (in the JSF specification it's called execute) you tell JSF to limit the processing to component that are specified every thing else is just ignored.
update indicates which element will be updated when the server respond back to you request.
@all : Every component is processed/rendered.
@this: The requesting component with the execute attribute is processed/rendered.
@form : The form that contains the requesting component is processed/rendered.
@parent: The parent that contains the requesting component is processed/rendered.
With Primefaces you can even use JQuery selectors, check out this blog: http://blog.primefaces.org/?p=1867
Load Testing: Load testing is meant to test the system by constantly and steadily increasing the load on the system till the time it reaches the threshold limit.
Example For example, to check the email functionality of an application, it could be flooded with 1000 users at a time. Now, 1000 users can fire the email transactions (read, send, delete, forward, reply) in many different ways. If we take one transaction per user per hour, then it would be 1000 transactions per hour. By simulating 10 transactions/user, we could load test the email server by occupying it with 10000 transactions/hour.
Stress Testing: Under stress testing, various activities to overload the existing resources with excess jobs are carried out in an attempt to break the system down.
Example: As an example, a word processor like Writer1.1.0 by OpenOffice.org is utilized in development of letters, presentations, spread sheets etc… Purpose of our stress testing is to load it with the excess of characters.
To do this, we will repeatedly paste a line of data, till it reaches its threshold limit of handling large volume of text. As soon as the character size reaches 65,535 characters, it would simply refuse to accept more data. The result of stress testing on Writer 1.1.0 produces the result that, it does not crash under the stress and that it handle the situation gracefully, which make sure that application is working correctly even under rigorous stress conditions.
Of the options you asked about:
float:left;
float
concept was poorly designed in the CSS specs. Nothing we can do about that now though. But the important thing is it does work, and it works in all browsers (even IE6/7), so use it if you like it.The additional markup for clearing may not be necessary if you use the :after
selector to clear the floats, but this isn't an option if you want to support IE6 or IE7.
display:inline;
This shouldn't be used for layout, with the exception of IE6/7, where display:inline; zoom:1
is a fall-back hack for the broken support for inline-block
.
display:inline-block;
This is my favourite option. It works well and consistently across all browsers, with a caveat for IE6/7, which support it for some elements. But see above for the hacky solution to work around this.
The other big caveat with inline-block
is that because of the inline aspect, the white spaces between elements are treated the same as white spaces between words of text, so you can get gaps appearing between elements. There are work-arounds to this, but none of them are ideal. (the best is simply to not have any spaces between the elements)
display:table-cell;
table-cell
is designed to be used in a context of being inside elements that are styled as table
and table-row
; using table-cell
in isolation is not the intended way to do it, so you may experience different browsers treating it differently.Other techniques you may have missed? Yes.
Since you say this is for a multi-column layout, there is a CSS Columns feature that you might want to know about. However it isn't the most well supported feature (not supported by IE even in IE9, and a vendor prefix required by all other browsers), so you may not want to use it. But it is another option, and you did ask.
There's also CSS FlexBox feature, which is intended to allow you to have text flowing from box to box. It's an exciting feature that will allow some complex layouts, but this is still very much in development -- see http://html5please.com/#flexbox
Hope that helps.

I suggest you to first try to understand Java 8 in the whole picture, most importantly in your case it will be streams, lambdas and method references.
You should never convert existing code to Java 8 code on a line-by-line basis, you should extract features and convert those.
What I identified in your first case is the following:
Let's see how we do that, we can do it with the following:
List<Player> playersOfTeam = players.stream()
.filter(player -> player.getTeam().equals(teamName))
.collect(Collectors.toList());
What you do here is:
Collection<Player>
, now you have a Stream<Player>
.Predicate<Player>
, mapping every player to the boolean true if it is wished to be kept.Collector
, here we can use one of the standard library collectors, which is Collectors.toList()
.This also incorporates two other points:
List<E>
over ArrayList<E>
.new ArrayList<>()
, you are using Java 8 after all.Now onto your second point:
You again want to convert something of legacy Java to Java 8 without looking at the bigger picture. This part has already been answered by @IanRoberts, though I think that you need to do players.stream().filter(...)...
over what he suggested.
The project JsonSubTypes implement a generic converter that handle this feature with the helps of attributes.
For the concrete sample provided here is how it works:
[JsonConverter(typeof(JsonSubtypes))]
[JsonSubtypes.KnownSubTypeWithProperty(typeof(Employee), "JobTitle")]
[JsonSubtypes.KnownSubTypeWithProperty(typeof(Artist), "Skill")]
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class Employee : Person
{
public string Department { get; set; }
public string JobTitle { get; set; }
}
public class Artist : Person
{
public string Skill { get; set; }
}
[TestMethod]
public void Demo()
{
string json = "[{\"Department\":\"Department1\",\"JobTitle\":\"JobTitle1\",\"FirstName\":\"FirstName1\",\"LastName\":\"LastName1\"}," +
"{\"Department\":\"Department1\",\"JobTitle\":\"JobTitle1\",\"FirstName\":\"FirstName1\",\"LastName\":\"LastName1\"}," +
"{\"Skill\":\"Painter\",\"FirstName\":\"FirstName1\",\"LastName\":\"LastName1\"}]";
var persons = JsonConvert.DeserializeObject<IReadOnlyCollection<Person>>(json);
Assert.AreEqual("Painter", (persons.Last() as Artist)?.Skill);
}
I had a similar problem where were my two horizontally weighted TextViews didn't wrap the text. I later found out that the issue was because my viewparents parent had wrap_content instead of match_parent.
This is the very basic
awk '/pattern/{ print $0 }' file
ask awk
to search for pattern
using //
, then print out the line, which by default is called a record, denoted by $0. At least read up the documentation.
If you only want to get print out the matched word.
awk '{for(i=1;i<=NF;i++){ if($i=="yyy"){print $i} } }' file
For big CLOB selects also can be used:
SELECT dbms_lob.substr( column_name, dbms_lob.getlength(column_name), 1) FROM foo
You can do it with a pivot
query, like this:
select * from (
select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
from my_table t
)
pivot
(
MIN(DOCUMENT_ID)
for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)
Here is a demo on sqlfiddle.com.
Use data URL scheme: https://en.wikipedia.org/wiki/Data_URI_scheme
In this case you use that string directly in html : <img src="data:image/png;base64,iVBOR....">
For anyone else looking to get the profile pic in iOS:
I just did this to get the user's Facebook pic:
NSString *profilePicURL = [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large", fbUserID];
where 'fbUserID' is the Facebook user's profile ID.
This way I can always just call the url in profilePicURL to get the image, and I always get it, no problem. If you've already got the user ID, you don't need any API requests, just stick the ID into the url after facebook.com/.
FYI to anyone looking who needs the fbUserID in iOS:
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *user,
NSError *error) {
if (!error) {
self.userName = user.name;
self.fbUserID = user.id;
}
}];
}
You'll need an active FBSession for that to work (see Facebook's docs, and the "Scrumptious" example).
First of all, parent-child scope relation does matter. You have two possibilities to emit some event:
$broadcast
-- dispatches the event downwards to all child scopes,$emit
-- dispatches the event upwards through the scope hierarchy.I don't know anything about your controllers (scopes) relation, but there are several options:
If scope of firstCtrl
is parent of the secondCtrl
scope, your code should
work by replacing $emit
by $broadcast
in firstCtrl
:
function firstCtrl($scope)
{
$scope.$broadcast('someEvent', [1,2,3]);
}
function secondCtrl($scope)
{
$scope.$on('someEvent', function(event, mass) { console.log(mass); });
}
In case there is no parent-child relation between your scopes you
can inject $rootScope
into the controller and broadcast the event
to all child scopes (i.e. also secondCtrl
).
function firstCtrl($rootScope)
{
$rootScope.$broadcast('someEvent', [1,2,3]);
}
Finally, when you need to dispatch the event from child controller
to scopes upwards you can use $scope.$emit
. If scope of firstCtrl
is parent of the secondCtrl
scope:
function firstCtrl($scope)
{
$scope.$on('someEvent', function(event, data) { console.log(data); });
}
function secondCtrl($scope)
{
$scope.$emit('someEvent', [1,2,3]);
}
As for the code example in the question, the standard solution is to reference the class explicitly by its name, and it is even possible to do without getClassLoader()
call:
class MyClass {
public static void startMusic() {
URL songPath = MyClass.class.getResource("background.midi");
}
}
This approach still has a back side that it is not very safe against copy/paste errors in case you need to replicate this code to a number of similar classes.
And as for the exact question in the headline, there is a trick posted in the adjacent thread:
Class currentClass = new Object() { }.getClass().getEnclosingClass();
It uses a nested anonymous Object
subclass to get hold of the execution context. This trick has a benefit of being copy/paste safe...
Caution when using this in a Base Class that other classes inherit from:
It is also worth noting that if this snippet is shaped as a static method of some base class then currentClass
value will always be a reference to that base class rather than to any subclass that may be using that method.

If you would like to have a histogram of unique values here's oneliner
import numpy as np
unique_labels, unique_counts = np.unique(labels_list, return_counts=True)
labels_histogram = dict(zip(unique_labels, unique_counts))
Damien_The_Unbeliever noted that his was only good for digits
Wade73 added a bit to handle decimal points
neizan made an additional tweak as did notwhereuareat
Unfortunately, none appear to handle negative values and they appear to have issues with a comma in the value...
Here's my tweak to pick up negative values and those with commas
declare @MyTable table(MyVar nvarchar(10));
insert into @MyTable (MyVar)
values
(N'1234')
, (N'000005')
, (N'1,000')
, (N'293.8457')
, (N'x')
, (N'+')
, (N'293.8457.')
, (N'......')
, (N'.')
, (N'-375.4')
, (N'-00003')
, (N'-2,000')
, (N'3-3')
, (N'3000-')
;
-- This shows that Neizan's answer allows "." to slip through.
select * from (
select
MyVar
, case when MyVar not like N'%[^0-9.]%' then 1 else 0 end as IsNumber
from
@MyTable
) t order by IsNumber;
-- Notice the addition of "and MyVar not like '.'".
select * from (
select
MyVar
, case when MyVar not like N'%[^0-9.]%' and MyVar not like N'%.%.%' and MyVar not like '.' then 1 else 0 end as IsNumber
from
@MyTable
) t
order by IsNumber;
--Trying to tweak for negative values and the comma
--Modified when comparison
select * from (
select
MyVar
, case
when MyVar not like N'%[^0-9.,-]%' and MyVar not like '.' and isnumeric(MyVar) = 1 then 1
else 0
end as IsNumber
from
@MyTable
) t
order by IsNumber;
With
with() is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.
Example:
User > hasMany > Post
$users = User::with('posts')->get();
foreach($users as $user){
$users->posts; // posts is already loaded and no additional DB query is run
}
Has
has() is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation') that means you only want to get the models that have at least one related model in this relation.
Example:
User > hasMany > Post
$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection
WhereHas
whereHas() works basically the same as has() but allows you to specify additional filters for the related model to check.
Example:
User > hasMany > Post
$users = User::whereHas('posts', function($q){
$q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned
This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.
MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
headers);
JSONObject jsonObject = null;
try {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> responseEntity = restTemplate.exchange(
"https://url", HttpMethod.POST, entity,
String.class);
if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
try {
jsonObject = new JSONObject(responseEntity.getBody());
} catch (JSONException e) {
throw new RuntimeException("JSONException occurred");
}
}
} catch (final HttpClientErrorException httpClientErrorException) {
throw new ExternalCallBadRequestException();
} catch (HttpServerErrorException httpServerErrorException) {
throw new ExternalCallServerErrorException(httpServerErrorException);
} catch (Exception exception) {
throw new ExternalCallServerErrorException(exception);
}
ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.
Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.
Consider the following scenario:
public class Car {
@Inject
private Engine engine;
public Car() {
engine.initialize();
}
...
}
Since Car has to be instantiated prior to field injection, the injection point engine is still null during the execution of the constructor, resulting in a NullPointerException.
This problem can be solved either by JSR-330 Dependency Injection for Java constructor injection or JSR 250 Common Annotations for the Java @PostConstruct method annotation.
@PostConstruct
JSR-250 defines a common set of annotations which has been included in Java SE 6.
The PostConstruct annotation is used on a method that needs to be executed after dependency injection is done to perform any initialization. This method MUST be invoked before the class is put into service. This annotation MUST be supported on all classes that support dependency injection.
JSR-250 Chap. 2.5 javax.annotation.PostConstruct
The @PostConstruct annotation allows for the definition of methods to be executed after the instance has been instantiated and all injects have been performed.
public class Car {
@Inject
private Engine engine;
@PostConstruct
public void postConstruct() {
engine.initialize();
}
...
}
Instead of performing the initialization in the constructor, the code is moved to a method annotated with @PostConstruct.
The processing of post-construct methods is a simple matter of finding all methods annotated with @PostConstruct and invoking them in turn.
private void processPostConstruct(Class type, T targetInstance) {
Method[] declaredMethods = type.getDeclaredMethods();
Arrays.stream(declaredMethods)
.filter(method -> method.getAnnotation(PostConstruct.class) != null)
.forEach(postConstructMethod -> {
try {
postConstructMethod.setAccessible(true);
postConstructMethod.invoke(targetInstance, new Object[]{});
} catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException ex) {
throw new RuntimeException(ex);
}
});
}
The processing of post-construct methods has to be performed after instantiation and injection have been completed.
In addition to others' proposals, there is another option to handle that issue.
If your application should behave the same in case of lack of "href
" attribute, as in case of it being empty, just replace this:
var theHref = $(obj.mainImg_select).attr('href');
with this:
var theHref = $(obj.mainImg_select).attr('href') || '';
which will treat empty string (''
) as the default, if the attribute has not been found.
But it really depends, on how you want to handle undefined "href
" attribute. This answer assumes you will want to handle it as if it was empty string.
[UPDATE] TL;DR pkg_resources
is provided by either Distribute or setuptools.
[UPDATE 2] As announced at PyCon 2013, the Distribute
and setuptools
projects have re-merged. Distribute
is now deprecated and you should just use the new current setuptools
. Try this:
curl -O https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
python ez_setup.py
Or, better, use a current pip
as the high level interface and which will use setuptools
under the covers.
[Longer answer for OP's specific problem]:
You don't say in your question but I'm assuming you upgraded from the Apple-supplied Python (2.5 on 10.5 or 2.6.1 on 10.6) or that you upgraded from a python.org Python 2.5. In any of those cases, the important point is that each Python instance has its own library, including its own site-packages library, which is where additional packages are installed. (And none of them use /usr/local/lib
by default, by the way.) That means you'll need to install those additional packages you need for your new python 2.6. The easiest way to do this is to first ensure that the new python2.6 appears first on your search $PATH
(that is, typing python2.6
invokes it as expected); the python2.6 installer should have modified your .bash_profile
to put its framework bin directory at the front of $PATH
. Then install easy_install
using setuptools following the instructions there. The pkg_resources
module is also automatically installed by this step.
Then use the newly-installed version of easy_install
(or pip
) to install ipython
.
easy_install ipython
or
pip install ipython
It should automatically get installed to the correct site-packages
location for that python instance and you should be good to go.
Call the marker.setIcon('newImage.png')
... Look here for the docs.
Are you asking about the actual way to do it? You could just create each div
, and a add a mouseover
and mouseout
listener that would change the icon and back for the markers.
I could also fix this. PYTHONPATH and PYTHONHOME were in cause.
run this in a terminal
touch ~/.bash_profile
open ~/.bash_profile
and then delete all useless parts of this file, and save. I do not know how recommended it is to do that !
You should use the ARG
directive in your Dockerfile which is meant for this purpose.
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.
So your Dockerfile will have this line:
ARG request_domain
or if you'd prefer a default value:
ARG request_domain=127.0.0.1
Now you can reference this variable inside your Dockerfile:
ENV request_domain=$request_domain
then you will build your container like so:
$ docker build --build-arg request_domain=mydomain Dockerfile
Note 1: Your image will not build if you have referenced an ARG
in your Dockerfile but excluded it in --build-arg
.
Note 2: If a user specifies a build argument that was not defined in the Dockerfile, the build outputs a warning:
[Warning] One or more build-args [foo] were not consumed.
To determine if you are at the end of your custom ScrollView
you could also use a member variable and store the last y-position. Then you can compare the last y-position with the current scroll position.
private int scrollViewPos;
...
@Override
public void onScrollChanged(ScrollViewExt scrollView, int x, int y, int oldx, int oldy) {
//reached end of scrollview
if (y > 0 && scrollViewPos == y){
//do something
}
scrollViewPos = y;
}
On a Mac, the "most efficient" way to install jq would probably be using homebrew, e.g.
brew install jq
If you want the development version, you could try:
brew install --HEAD jq
but this has various pre-requisites.
Detailed instructions are on the "Installation" page of the jq wiki: https://github.com/stedolan/jq/wiki/Installation
The same page also includes details regarding installation from source, and has notes on installing with MacPorts.
UPDATE: In Oracle 12c onward we have an option to create auto increment field, its better than trigger and sequence.
See the below image
From SQL Statement
IDENTITY column is now available on Oracle 12c:
create table t1 (
c1 NUMBER GENERATED by default on null as IDENTITY,
c2 VARCHAR2(10)
);
or specify starting and increment values, also preventing any insert into the identity column (GENERATED ALWAYS) (again, Oracle 12c+ only)
create table t1 (
c1 NUMBER GENERATED ALWAYS as IDENTITY(START with 1 INCREMENT by 1),
c2 VARCHAR2(10)
);
EDIT : if you face any error like "ORA-30673: column to be modified is not an identity column", then you need to create new column and delete the old one.
It's still an attribute. Setting it to:
<input type="button" name=myButton value="disable" disabled="disabled">
... is valid.
Be careful using
SET sql_mode = ''
This actually clears all the modes currently enabled. If you don't want to mess with other settings, you'll want to do a
SELECT @@sql_mode
first, to get a comma-separated list of the modes enabled, then SET it to this list without the ONLY_FULL_GROUP_BY
option.
A more compact and efficient way would be perhaps:
cols = ['frame', 'count']
N = 4
dat = pd.DataFrame(columns = cols)
for i in range(N):
dat = dat.append({'frame': str(i), 'count':i},ignore_index=True)
output would be:
>>> dat
frame count
0 0 0
1 1 1
2 2 2
3 3 3
If you want to do links and other types of rich text, a more comprehensive solution is to use React Native HTMLView.
I have an example which I have been using for couple years. Please take a look as a reference.
This wroks for me(in CoffeeScript)
$location.path '/url/path'
$scope.$apply() if (!$scope.$$phase)
If you are using Action, Actionforward way to process business logic and next page to show, check out if redirect is called. As many others pointed out, redirecting doesn't keep your original request since it is basically forcing you to make a new request to designated path. So the value set in original request will be vanished if you use redirection instead of requestdispatch.
This works in both SQL 2005 and 2008:
declare @source varbinary(max);
set @source = 0x21232F297A57A5A743894A0E4A801FC3;
select cast('' as xml).value('xs:hexBinary(sql:variable("@source"))', 'varchar(max)');
Press Ctl+T
will open a search box. Delete # symbol and enter your file name.
The simplest method is just to use the +
operator, which returns the concatenation of the lists:
concat = first_list + second_list
One disadvantage of this method is that twice the memory is now being used . For very large lists, depending on how you're going to use it once it's created, itertools.chain
might be your best bet:
>>> import itertools
>>> a = [1, 2, 3]
>>> b = [4, 5, 6]
>>> c = itertools.chain(a, b)
This creates a generator for the items in the combined list, which has the advantage that no new list needs to be created, but you can still use c
as though it were the concatenation of the two lists:
>>> for i in c:
... print i
1
2
3
4
5
6
If your lists are large and efficiency is a concern then this and other methods from the itertools
module are very handy to know.
Note that this example uses up the items in c
, so you'd need to reinitialise it before you can reuse it. Of course you can just use list(c)
to create the full list, but that will create a new list in memory.
You can add directories to your ctags lookup. For example, I have a ctags index built for Qt4, and have this in my .vimrc:
set tags+=/usr/local/share/ctags/qt4
Why not use document.documentMode
only available under IE:
var doc = $window.document;
if (!!doc.documentMode)
{
if (doc.documentMode === 10)
{
doc.documentElement.className += ' isIE isIE10';
}
else if (doc.documentMode === 11)
{
doc.documentElement.className += ' isIE isIE11';
}
// etc.
}
//declaration
list: Array<any> = new Array<any>();
//remove item from an array
removeitem()
{
const index = this.list.findIndex(user => user._id === 2);
this.list.splice(index, 1);
}
This adds to rm8x's answer.
Download and install the NuGet command line tool.

for (var i = params_arr.length - 1; i >= 0; i -= 1) {
param = params_arr[i].split("=")[0];
if (param === key) {
params_arr.splice(i, 1);
}
}
if (params_arr.length) rtn = rtn + "?" + params_arr.join("&");
}
return rtn;
}
To use it, simply do something like this:
var originalURL = "http://yourewebsite.com?id=10&color_id=1";
var alteredURL = removeParam("color_id", originalURL);
The var alteredURL
will be the output you desire.
Hope it helps!
You can use Copy database ... right click on the remote database ... select tasks and use copy database ... it will asks you about source server and destination server . that your source is the remote and destination is your local instance of sql server.
it's that easy
I found a tool called ttyplot
in homebrew. It's good. https://github.com/tenox7/ttyplot
I just used a model variable to show/hide the dialog and removed the data-dismiss="alert"
Example:
<div data-ng-show="vm.result == 'error'" class="alert alert-danger alert-dismissable">
<button type="button" class="close" data-ng-click="vm.result = null" aria-hidden="true">×</button>
<strong>Error ! </strong>{{vm.exception}}
</div>
works for me and stops the need to go out to jquery
A working example for Twitter bootstrap NOT STICKY FOOTER
<script>
$(document).ready(function() {
var docHeight = $(window).height();
var footerHeight = $('#footer').height();
var footerTop = $('#footer').position().top + footerHeight;
if (footerTop < docHeight)
$('#footer').css('margin-top', 10+ (docHeight - footerTop) + 'px');
});
</script>
Version that always updates in case user opens devtools or resizes window.
<script>
$(document).ready(function() {
setInterval(function() {
var docHeight = $(window).height();
var footerHeight = $('#footer').height();
var footerTop = $('#footer').position().top + footerHeight;
var marginTop = (docHeight - footerTop + 10);
if (footerTop < docHeight)
$('#footer').css('margin-top', marginTop + 'px'); // padding of 30 on footer
else
$('#footer').css('margin-top', '0px');
// console.log("docheight: " + docHeight + "\n" + "footerheight: " + footerHeight + "\n" + "footertop: " + footerTop + "\n" + "new docheight: " + $(window).height() + "\n" + "margintop: " + marginTop);

The scrollbar will show up if content not fits to screen.
I had trouble getting selectable to work with ASP.NET. It turns out I wasn't properly including everything, but this gentleman made it foolproof: Three steps to use jQuery UI in ASP.NET MVC 5.
Another answer for the first question is to use one for loop and perform linear indexing into the array using the function NUMEL to get the total number of elements:
total = 0;
for i = 1:numel(A)
total = total+A(i);
end
If you using Linux or Ubuntu than you can directly extract data from .war

A war

This is how I come up with the IP
func ReadUserIP(r *http.Request) string {
IPAddress := r.Header.Get("X-Real-Ip")
if IPAddress == "" {
IPAddress = r.Header.Get("X-Forwarded-For")
}
if IPAddress == "" {
IPAddress = r.RemoteAddr
}
return IPAddress
}
X-Real-Ip - fetches first true IP (if the requests sits behind multiple NAT sources/load balancer)
X-Forwarded-For - if for some reason X-Real-Ip is blank and does not return response, get from X-Forwarded-For
AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.
As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.
So AArch64 and ARM64 refer to the same thing.
Here is another concrete example.It is for a shared library. The shared library's main function is to communicate with a smart card reader. But it can also receive 'configuration information' at runtime over udp. The udp is handled by a thread which MUST be started at init time.
__attribute__((constructor)) static void startUdpReceiveThread (void) {
pthread_create( &tid_udpthread, NULL, __feigh_udp_receive_loop, NULL );
return;
}
The library was written in c.
You remove the original image here:
newImg.animate(css, SPEED, function() {
img.remove();
newImg.removeClass('morpher');
(callback || function() {})();
});
And all that's left behind is newImg
. Then you reset link references the image using #rocket
:
$("#rocket").attr('src', ...
But your newImg
doesn't have an id
attribute let alone an id
of rocket
.
To fix this, you need to remove img
and then set the id
attribute of newImg
to rocket
:
newImg.animate(css, SPEED, function() {
var old_id = img.attr('id');
img.remove();
newImg.attr('id', old_id);
newImg.removeClass('morpher');
(callback || function() {})();
});
And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/
UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:
$("#resetlink").click(function(){
clearInterval(timerRocket);
$("#wrapper").css('top', '250px');
$('.throbber, .morpher').remove(); // Clear out the new stuff.
$("#rocket").show(); // Bring the original back.
});
And in the newImg.load
function, grab the images original size:
var orig = {
width: img.width(),
height: img.height()
};
And finally, the callback for finishing the morphing animation becomes this:
newImg.animate(css, SPEED, function() {
img.css(orig).hide();
(callback || function() {})();
});
New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/
The leaking of $('.throbber, .morpher')
outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.
I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.
Bootstrap requires a specific file structure to work. I see from your code you have this:
<link href="bootstrap.css" rel="stylesheet" media="screen">
Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.
But first, let me recommend you setup your folder structure like so:
/css <-- Bootstrap.css here
/fonts <-- Bootstrap fonts here
/img
/js <-- Bootstrap JavaScript here
index.html
If you notice, this is also how Bootstrap structures its files in its download ZIP.
You then include your Bootstrap file like so:
<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">
Depending on your server structure or what you're going for.
The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).
The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.
So, why do this?
Bootstrap.css has this specific line for Glyphfonts:
@font-face {
font-family: 'Glyphicons Halflings';
src: url('../fonts/glyphicons-halflings-regular.eot');
src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
What you can see is that that Glyphfonts are loaded by going up one directory ../
and then looking for a folder called /fonts
and THEN loading the font file.
The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:
/fonts
Bootstrap.css
index.html
The CSS file is going one level deeper than looking for a /fonts
folder.
So, let's say the actual location of these files are:
C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html
The CSS file would technically be looking for a folder at:
C:\fonts
but your folder is actually in:
C:\www\fonts
So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.
When you get that fixed, your HTML should simply be:
<span class="glyphicon glyphicon-comment"></span>
Note, you need both classes. The first class glyphicon
sets up the basic styles while glyphicon-comment
sets the specific image.
Replace '\n'
with "\n"
. The escape sequence is not recognized when you use '
.
See the manual.
For the question of how to write line endings, see the note here. Basically, different operating systems have different conventions for line endings. Windows uses "\r\n", unix based operating systems use "\n". You should stick to one convention (I'd chose "\n") and open your file in binary mode (fopen
should get "wb", not "w").
As known this was a path issue.
the base of my custom packages shared a name with a directory set in a /etc/profile. The packages were in a different location however for the webserver. So I removed the offending entries from my $PYTHONPATH and was good to go!
Thanks for the help.
This is the easiest way I found

Asp.net is pretty good at automatically converting .net objects to json. Your List object if returned in your webmethod should return a json/javascript array. What I mean by this is that you shouldn't change the return type to string (because that's what you think the client is expecting) when returning data from a method. If you return a .net array from a webmethod a javaScript array will be returned to the client. It doesn't actually work too well for more complicated objects, but for simple array data its fine.
Of course, it's then up to you to do what you need to do on the client side.
I would be thinking something like this:
[WebMethod]
public static List GetProducts()
{
var products = context.GetProducts().ToList();
return products;
}
There shouldn't really be any need to initialise any custom converters unless your data is more complicated than simple row/col data
This code is returning size height according to text
+ (CGFloat)findHeightForText:(NSString *)text havingWidth:(CGFloat)widthValue andFont:(UIFont *)font
{
CGFloat result = font.pointSize+4;
if (text)
{
CGSize size;
CGRect frame = [text boundingRectWithSize:CGSizeMake(widthValue, 999)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:@{NSFontAttributeName:font}
context:nil];
size = CGSizeMake(frame.size.width, frame.size.height+1);
result = MAX(size.height, result); //At least one row
}
return result;
}
Ditch FileWriter
and FileReader
, which are useless exactly because they do not allow you to specify the encoding. Instead, use
new OutputStreamWriter(new FileOutputStream(file), StandardCharsets.UTF_8)
and
new InputStreamReader(new FileInputStream(file), StandardCharsets.UTF_8);
Add this extension in your code and change image color in storyboard itself.
Swift 4 & 5:
extension UIImageView {
@IBInspectable
var changeColor: UIColor? {
get {
let color = UIColor(cgColor: layer.borderColor!);
return color
}
set {
let templateImage = self.image?.withRenderingMode(.alwaysTemplate)
self.image = templateImage
self.tintColor = newValue
}
}
}

Both are different. Postman calls "POST" properly, but when we call it, it will be "OPTIONS".
For C# web services - Web API

<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />

On Boostrap 4 simply add mx-auto
to your carousel image class.
<div class="carousel-item">
<img class="d-block mx-auto" src="http://placehold.it/600x400" />
</div>
Combine with the samples from the bootstrap carousel documentation as desired.
In your test, you are comparing the two TestParent
beans, not the single TestedChild
bean.
Also, Spring proxies your @Configuration
class so that when you call one of the @Bean
annotated methods, it caches the result and always returns the same object on future calls.

Actually, both INSTALLPATH/TARGETDIR
are correct. It depends on how MSI processes this.
I create a MSG using wixToolSet
. In WXS file, there is "Directory" Node, which root dir maybe like the following:
<Directory Id="**TARGETDIR**" Name="SourceDir">;
As you can see: Id
is which you should use.
Due to mantain compatibility with ie7, ie8 I suggest using first-child and not last-child to doing this:
table tr td{border-top:1px solid #ffffff;border-left:1px solid #ffffff;}
table tr td:first-child{border-left:0;}
table tr:first-child td{border-top:0;}

Taking what others have already said above. Here is a one-liner that puts the answer into a text file formatted, json.
curl "http://mydocker.registry.domain/v2/_catalog?n=2000" | jq . - > /tmp/registry.lst
This looks like
{
"repositories": [
"somerepo/somecontiner",
"somerepo_other/someothercontiner",
...
]
}
You might need to change the `?n=xxxx' to match how many containers you have.
Next is a way to automatically remove old and unused containers.
There are 2 following ways preferred to stop a thread.
Create a volatile boolean variable and change its value to false and check inside the thread.
volatile isRunning = false;
public void run() {
if(!isRunning) {return;}
}
Or you can use the interrupt() method which can be receive inside a thread.
SomeThread.interrupt();
public void run() {
if(Thread.currentThread.isInterrupted()) {return;}
}

You can use HttpClient and HttpPost to send a json string as body:
public void post(String completeUrl, String body) {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(completeUrl);
httpPost.setHeader("Content-type", "application/json");
try {
StringEntity stringEntity = new StringEntity(body);
httpPost.getRequestLine();
httpPost.setEntity(stringEntity);
httpClient.execute(httpPost);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
Json body example:
{
"param1": "value 1",
"param2": 123,
"testStudentArray": [
{
"name": "Test Name 1",
"gpa": 3.5
},
{
"name": "Test Name 2",
"gpa": 3.8
}
]
}

Variation on the builder pattern, using call():
function asyncMethod(arg) {
function innerPromise() { return new Promise((...)=> {...}) }
innerPromise().then(result => {
this.setStuff(result);
}
}
const getInstance = async (arg) => {
let instance = new Instance();
await asyncMethod.call(instance, arg);
return instance;
}
I find another way of doing the same thing by using @PathParam
. Here is the code sample.
@GET
@Path("data/xml/{Ids}")
@Produces("application/xml")
public Object getData(@PathParam("zrssIds") String Ids)
{
System.out.println("zrssIds = " + Ids);
//Here you need to use String tokenizer to make the array from the string.
}
Call the service by using following url.
http://localhost:8080/MyServices/resources/cm/data/xml/12,13,56,76
where
http://localhost:8080/[War File Name]/[Servlet Mapping]/[Class Path]/data/xml/12,13,56,76
What is your PHP version? Extension "Mysql" was deprecated in PHP 5.5.0. Use extension Mysqli (like mysqli_query).
Another option now may be HTML5 text to speech, which is in Chrome 33+ and many others.
Here is a sample:
var msg = new SpeechSynthesisUtterance('Hello World');
window.speechSynthesis.speak(msg);
With this, perhaps you do not need to use a web service at all.
>>> a=$("#communitymode")[0]
<input id="communitymode" type="checkbox" name="communitymode">
>>> a.type
"checkbox"
Or, more of the style of jQuery:
$("#myinput").attr('type') == 'checkbox'
Easy and simple way to quit from the application
Intent homeIntent = new Intent(Intent.ACTION_MAIN);
homeIntent.addCategory(Intent.CATEGORY_HOME);
homeIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

The real answer is you need to set the escape character to '\': SET ESCAPE ON
The problem may have occurred either because escaping was disabled, or the escape character was set to something other than '\'. The above statement will enable escaping and set it to '\'.
None of the other answers previously posted actually answer the original question. They all work around the problem but don't resolve it.

In my case it is because the server is giving http error occasionally. So basically once in a while my script gets the response like this rahter than the expected response:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html>
<head><title>502 Bad Gateway</title></head>
<body bgcolor="white">
<h1>502 Bad Gateway</h1>
<p>The proxy server received an invalid response from an upstream server.<hr/>Powered by Tengine</body>
</html>
Clearly this is not in json format and trying to call .json()
will yield JSONDecodeError: Expecting value: line 1 column 1 (char 0)
You can print the exact response that causes this error to better debug.
For example if you are using requests
and then simply print the .text
field (before you call .json()
) would do.
Well, REST by design is stateless. By adding session (or anything else of that kind) you are making it stateful and defeating any purpose of having a RESTful API.
The whole idea of RESTful service is that every resource is uniquely addressable using a universal syntax for use in hypermedia links and each HTTP request should carry enough information by itself for its recipient to process it to be in complete harmony with the stateless nature of HTTP".
So whatever you are trying to do with Web API here, should most likely be re-architectured if you wish to have a RESTful API.
With that said, if you are still willing to go down that route, there is a hacky way of adding session to Web API, and it's been posted by Imran here http://forums.asp.net/t/1780385.aspx/1
Code (though I wouldn't really recommend that):
public class MyHttpControllerHandler
: HttpControllerHandler, IRequiresSessionState
{
public MyHttpControllerHandler(RouteData routeData): base(routeData)
{ }
}
public class MyHttpControllerRouteHandler : HttpControllerRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
return new MyHttpControllerHandler(requestContext.RouteData);
}
}
public class ValuesController : ApiController
{
public string GET(string input)
{
var session = HttpContext.Current.Session;
if (session != null)
{
if (session["Time"] == null)
{
session["Time"] = DateTime.Now;
}
return "Session Time: " + session["Time"] + input;
}
return "Session is not availabe" + input;
}
}
and then add the HttpControllerHandler to your API route:
route.RouteHandler = new MyHttpControllerRouteHandler();
I think you are a bit confused. You should read a good tutorial/book on pointers.
This tutorial is very good for starters(clearly explains what &
and *
are). And yeah don't forget to read the book Pointers in C by Kenneth Reek.
The difference between &
and *
is very clear.
Example:
#include <stdio.h>
int main(){
int x, *p;
p = &x; /* initialise pointer(take the address of x) */
*p = 0; /* set x to zero */
printf("x is %d\n", x);
printf("*p is %d\n", *p);
*p += 1; /* increment what p points to i.e x */
printf("x is %d\n", x);
(*p)++; /* increment what p points to i.e x */
printf("x is %d\n", x);
return 0;
}
I was struggling with this question because I was looking for a way to do this in a bash script for OS X, hence /etc/passwd was out of the question, and my script was meant to be executed as root, therefore making the solutions invoking eval or bash -c dangerous as they allowed code injection into the variable specifying the username.
Here is what I found. It's simple and doesn't put a variable inside a subshell. However it does require the script to be ran by root as it sudos into the specified user account.
Presuming that $SOMEUSER contains a valid username:
echo "$(sudo -H -u "$SOMEUSER" -s -- "cd ~ && pwd")"
I hope this helps somebody!
Are you running the query in the correct database? i.e.,
Use MyDatabase;
GO
EXEC sp_rename 'ENG_TEst.[ENG_Test_A/C_TYPE]', 'ENG_Test_AC_TYPE', 'COLUMN';
GO
Your client application and server application must be under same domain, for example :
client - localhost
server - localhost
and not :
client - localhost:21234
server - localhost
You should also look at jQuery.support. Feature detection is a lot more reliable than browser detection for coding your functionality (unless you are just trying to log browser versions).
Bcrypt is a one-way hashing algorithm, you can't decrypt hashes. Use password_verify to check whether a password matches the stored hash:
<?php
// See the password_hash() example to see where this came from.
$hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq';
if (password_verify('rasmuslerdorf', $hash)) {
echo 'Password is valid!';
} else {
echo 'Invalid password.';
}
In your case, run the SQL query using only the username:
$sql_script = 'SELECT * FROM USERS WHERE username=?';
And do the password validation in PHP using a code that is similar to the example above.
The way you are constructing the query is very dangerous. If you don't parameterize the input properly, the code will be vulnerable to SQL injection attacks. See this Stack Overflow answer on how to prevent SQL injection.
Apache FileUtil gives very handy methods to do the conversion

}
When you run the Windows Command Prompt, and type in python
, it starts the Python interpreter.
Typing it again tries to interpret python
as a variable, which doesn't exist and thus won't work:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\USER>python

If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python
is interpreted as a variable, which you have not defined.

Code::Blocks is cross-platform, using the wxWidgets library. It's the one I use.
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. */
I normally use this little awk
snippet for this requirement:
awk '{for (i=1; i<=NF; i++) a[i,NR]=$i
max=(max<NF?NF:max)}
END {for (i=1; i<=max; i++)
{for (j=1; j<=NR; j++)
printf "%s%s", a[i,j], (j==NR?RS:FS)
}
}' file
This just loads all the data into a bidimensional array a[line,column]
and then prints it back as a[column,line]
, so that it transposes the given input.
This needs to keep track of the max
imum amount of columns the initial file has, so that it is used as the number of rows to print back.
I would do it like this:
my $file = "index.html";
my $document = do {
local $/ = undef;
open my $fh, "<", $file
or die "could not open $file: $!";
<$fh>;
};
Note the use of the three-argument version of open. It is much safer than the old two- (or one-) argument versions. Also note the use of a lexical filehandle. Lexical filehandles are nicer than the old bareword variants, for many reasons. We are taking advantage of one of them here: they close when they go out of scope.
If you have installed Visual studio 2017 (profressional)
The install location:
C:\ProgramData\Anaconda3\Scripts
If you do not want the hassle of putting this in your path environment variable on windows and restarting you can run it by simply:
C:\>"C:\ProgramData\Anaconda3\Scripts\conda.exe" update qt pyqt
Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.
$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0
git-status
on the parent repository will now report a dirty tree:
# On branch dev [...]
#
# modified: submodule (new commits)
Add the submodule directory and commit to store the new pointer.
Go to the repository folder. Delete relevant submodules from .gitmodules. Select show hidden files. Go to .git folder, delete the submodules from module folder and config.
You are looking for System.Reflection.Assembly.GetExecutingAssembly()
string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string xmlFileName = Path.Combine(assemblyFolder,"AggregatorItems.xml");
Note:
The .Location
property returns the location of the currently running DLL file.
Under some conditions the DLL is shadow copied before execution, and the .Location
property will return the path of the copy. If you want the path of the original DLL, use the Assembly.GetExecutingAssembly().CodeBase
property instead.
.CodeBase
contains a prefix (file:\
), which you may need to remove.
Could you compare the output of this?
ls -A /some/dir | wc -l
This question is similar to How do I limit the number of rows returned by an Oracle query after ordering?.
It talks about how to implement a MySQL limit on an oracle database which judging by your tags and post is what you are using.
The relevant section is:

( select *
from emp
order by sal desc )
where ROWNUM <= 5;
As apps run in the background anyway. I’m assuming what your really asking is how do you make apps do stuff in the background. The solution below will make your app do stuff in the background after opening the app and after the system has rebooted.
Below, I’ve added a link to a fully working example (in the form of an Android Studio Project)
This subject seems to be out of the scope of the Android docs, and there doesn’t seem to be any one comprehensive doc on this. The information is spread across a few docs.
The following docs tell you indirectly how to do this: https://developer.android.com/reference/android/app/Service.html
https://developer.android.com/reference/android/content/BroadcastReceiver.html
https://developer.android.com/guide/components/bound-services.html
In the interests of getting your usage requirements correct, the important part of this above doc to read carefully is: #Binder, #Messenger and the components link below:
https://developer.android.com/guide/components/aidl.html
Here is the link to a fully working example (in Android Studio format): http://developersfound.com/BackgroundServiceDemo.zip
This project will start an Activity which binds to a service; implementing the AIDL.
This project is also useful to re-factor for the purpose of IPC across different apps.
This project is also developed to start automatically when Android restarts (provided the app has been run at least one after installation and app is not installed on SD card)
When this app/project runs after reboot, it dynamically uses a transparent view to make it look like no app has started but the service of the associated app starts cleanly.
This code is written in such a way that it’s very easy to tweak to simulate a scheduled service.
This project is developed in accordance to the above docs and is subsequently a clean solution.
There is however a part of this project which is not clean being: I have not found a way to start a service on reboot without using an Activity. If any of you guys reading this post have a clean way to do this please post a comment.
Same solution suggested by Tres without using jQuery
<form onsubmit="document.getElementById('mysel').disabled = false;" action="..." method="GET">
<select id="mysel" disabled="disabled">....</select>
<input name="submit" id="submit" type="submit" value="SEND FORM">
</form>
This might help someone understand more, but obviously is less flexible than the jQuery one.
Something that sometimes crops up you may/maynot be aware of
Won't always be picked up by by $_POST['delete'] when using IE. Firefox and chrome should work fine though. I use a seperate isntead which solves the problem for IE
As for your not deleting in your code above you appear to be echoing out 2x sets of check boxes both pulling the same data? Is this just a copy + paste mistake or is this actually how your code is?
If its how your code is that'll be the problem as the user could be ticking one checkbox array item but the other one will be unchecked so the php code for delete is getting confused. Either rename the 2nd check box or delete that block of html surely you don't need to display the same list twice ?
?:
is used when you want to group an expression, but you do not want to save it as a matched/captured portion of the string.
An example would be something to match an IP address:
/(?:\d{1,3}\.){3}\d{1,3}/
Note that I don't care about saving the first 3 octets, but the (?:...)
grouping allows me to shorten the regex without incurring the overhead of capturing and storing a match.
You need to see if the Type of your instance is equal to the Type of the class. To get the type of the instance you use the GetType()
method:
u.GetType().Equals(t);
or
u.GetType.Equals(typeof(User));
should do it. Obviously you could use '==' to do your comparison if you prefer.
I had the exact same error message, and tried the suggested solutions in this thread but without success.
what solved the problem for me is opening the .xlsx file and saving it as .xls (excel 2003) file.
maybe the file was corrupted or in a different format, and saving it again fixed it.
If the original poster was actually wanting to set an existing column to be a PRIMARY KEY
for the table and actually did not need the column to be an IDENTITY
column (two different things) then this can be done via t-SQL with:
ALTER TABLE [YourTableName]
ADD CONSTRAINT [ColumnToSetAsPrimaryKey] PRIMARY KEY ([ColumnToSetAsPrimaryKey])
Note the parenthesis around the column name after the PRIMARY KEY
option.
Although this post is old and I am making an assumption about the requestors need, I felt this additional information could be helpful to users encountering this thread as I believe the conversation could lead one to believe that an existing column can not be set to be a primary key without adding it as a new column first which would be incorrect.
It can also be done using backtracking by maintaining a visited array.
void foo(vector<vector<int> > &s,vector<int> &data,int go,int k,vector<int> &vis,int tot)
{
vis[go]=1;
data.push_back(go);
if(data.size()==k)
{
s.push_back(data);
vis[go]=0;
data.pop_back();
return;
}
for(int i=go+1;i<=tot;++i)
{
if(!vis[i])
{
foo(s,data,i,k,vis,tot);
}
}
vis[go]=0;
data.pop_back();
}
vector<vector<int> > Solution::combine(int n, int k) {
vector<int> data;
vector<int> vis(n+1,0);
vector<vector<int> > sol;
for(int i=1;i<=n;++i)
{
for(int i=1;i<=n;++i) vis[i]=0;
foo(sol,data,i,k,vis,n);
}
return sol;
}
Here is how I would write a validator for MaxValue
public class MaxValueAttribute : ValidationAttribute
{
private readonly int _maxValue;
public MaxValueAttribute(int maxValue)
{
_maxValue = maxValue;
}
public override bool IsValid(object value)
{
return (int) value <= _maxValue;
}
}
The MinValue Attribute should be fairly the same
In FF also CSS filter works fine. E.g. hue-rotate:
option {
filter: hue-rotate(90deg);
}
Also You Can Use Server.Execute
The Linq extension method Any could work for you...
buildingStatus.Any(item => item.GetCharValue() == v.Status)
Just expanding the answers:
Spacer
is an option no one mentioned yet; it is used in case you prefer not to use Positioned
/ Align
.Align
works if you want to specify the alignment of a child inside a parent. Use it anywhere but directly inside Stack
Positioned
is similar to Align, but works only under Stack
directly.This doesn't address the OP's question, but for anyone who is returning results from a database: here's a simple method I used.
If the user didn't upload an avatar the avatar
field would be NULL
, so I'd insert a default avatar image from the img
directory.
function getAvatar(avatar) {
if(avatar == null) {
return '/img/avatar.jpg';
} else {
return '/avi/' + avatar;
}
}
then
<img src="' + getAvatar(data.user.avatar) + '" alt="">
Those settings (core.whitespace
and apply.whitespace
) are not there to remove trailing whitespace but to:
core.whitespace
: detect them, and raise errors apply.whitespace
: and strip them, but only during patch, not "always automatically"I believe the git hook pre-commit
would do a better job for that (includes removing trailing whitespace)
Note that at any given time you can choose to not run the pre-commit
hook:
git commit --no-verify .
cd .git/hooks/ ; chmod -x pre-commit
Warning: by default, a pre-commit
script (like this one), has not a "remove trailing" feature", but a "warning" feature like:
if (/\s$/) {
bad_line("trailing whitespace", $_);
}
You could however build a better pre-commit
hook, especially when you consider that:
Committing in Git with only some changes added to the staging area still results in an “atomic” revision that may never have existed as a working copy and may not work.
For instance, oldman proposes in another answer a pre-commit
hook which detects and remove whitespace.
Since that hook get the file name of each file, I would recommend to be careful for certain type of files: you don't want to remove trailing whitespace in .md
(markdown) files!
First you should use print_r($_FILES)
to debug, and see what it contains. :
your uploads.php
would look like:
//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);
//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];
//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
//Tells you if its all ok
echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;
//Writes the information to the database
mysql_query("INSERT INTO picture (Filename,Description)
VALUES ('$Filename', '$Description')") ;
} else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>
EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php

For those who don't have pip installed, I found this quick script on github (works with Python 2.7.13):
import pkg_resources
distros = pkg_resources.AvailableDistributions()
for key in distros:
print distros[key]
In my case running c:\windows\Microsoft.Net\Framework64\v4.0.30319\aspnet_regiis.exe /i resolved the 403 access denied issue.
Setting cookie in the express is easy
npm install cookie parser
const cookieParser = require('cookie-parser');
app.use(cookieParser());
res.cookie('cookieName', '1', { expires: new Date(Date.now() + 900000), httpOnly: true })
console.dir(req.cookies.cookieName)
You could write an extension method:
public static class Extension
{
public static bool IsNumeric(this string s)
{
float output;
return float.TryParse(s, out output);
}
}
When you declare a variable as here
int a[10][10];
you are telling the C++ compiler that you want 100 consecutive integers allocated in the program's memory at runtime. The compiler will then provide for your program to have that much memory available and all is well with the world.
If however you tell the compiler
int x = 9001;
int y = 5;
int a[x][y];
the compiler has no way of knowing how much memory you are actually going to need at run time without doing a lot of very complex analysis to track down every last place where the values of x and y changed [if any]. Rather than support such variable size arrays, C++ and C strongly suggest if not outright demand that you use malloc() to manually allocate the space you want.
TL;DR
int x = 5;
int y = 5;
int **a = malloc(x*sizeof(int*));
for(int i = 0; i < y; i++) {
a[i] = malloc(sizeof(int*)*y);
}
a is now a 2D array of size 5x5 and will behave the same as int a[5][5]. Because you have manually allocated memory, C++ and C demand that you delete it by hand too...
for(int i = 0; i < x; i++) {
free(a[i]); // delete the 2nd dimension array
}
free(a); // delete a itself
You would do:
char c = str[1];
Or even:
char c = "Hello"[1];
edit: updated to find the "E".
Usually git bash here
can be run only on directories so you have to go up a directory and right click on the previous directory then select git bash here
(of course on Windows OS).
Note: context menu inside a directory does not have a git bash here
option.
It looks like you were on the right track - get_FOO_display()
is most certainly what you want:
In templates, you don't include ()
in the name of a method. Do the following:
{{ person.get_gender_display }}

DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
DECLARE @cnt int

EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75)', @city = @city
RETURN @cnt
More recent versions have a different syntax:
var table = $('#example').DataTable();
// #myInput is a <input type="text"> element
$('#myInput').on('keyup change', function () {
table.search(this.value).draw();
});
Note that this example uses the variable table
assigned when datatables is first initialised. If you don't have this variable available, simply use:
var table = $('#example').dataTable().api();
// #myInput is a <input type="text"> element
$('#myInput').on('keyup change', function () {
table.search(this.value).draw();
});
Since: DataTables 1.10
with open('target.txt','w') as out:
line1 = raw_input("line 1: ")
line2 = raw_input("line 2: ")
line3 = raw_input("line 3: ")
print("I'm going to write these to the file.")
out.write('{}\n{}\n{}\n'.format(line1,line2,line3))

Dependency Injection in an ASP.NET project can be accomplished with a few lines of code. I suppose there is some advantage to using a container when you have an app that uses multiple front ends and needs unit tests.
This is a very late response, but adds some detail on the previous answers
When it comes to calling static methods in PHP from another static method on the same class, it is important to differentiate between self
and the class name.
Take for instance this code:
class static_test_class {
public static function test() {
echo "Original class\n";
}
public static function run($use_self) {
if($use_self) {
self::test();
} else {
$class = get_called_class();
$class::test();
}
}
}
class extended_static_test_class extends static_test_class {
public static function test() {
echo "Extended class\n";
}
}
extended_static_test_class::run(true);
extended_static_test_class::run(false);
The output of this code is:
Original class
Extended class
This is because self
refers to the class the code is in, rather than the class of the code it is being called from.
If you want to use a method defined on a class which inherits the original class, you need to use something like:
$class = get_called_class();
$class::function_name();
If you don't need to initiate a post back when you press this button, then making the overhead of a server control isn't necesary.
<input id="addButton" type="button" value="Add" />
<script type="text/javascript" language="javascript">
$(document).ready(function()
{
$('#addButton').click(function()
{
showDialog('#addPerson');
});
});
</script>
If you still need to be able to do a post back, you can conditionally stop the rest of the button actions with a little different code:
<asp:Button ID="buttonAdd" runat="server" Text="Add" />
<script type="text/javascript" language="javascript">
$(document).ready(function()
{
$('#<%= buttonAdd.ClientID %>').click(function(e)
{
showDialog('#addPerson');
if(/*Some Condition Is Not Met*/)
return false;
});
});
</script>
pgBadger is another option - also listed here: https://github.com/dhamaniasad/awesome-postgres#utilities
Requires some additional setup in advance to capture the necessary data in the postgres logs though, see the official website.
On rails 4.2.2, go to application.rb
and use config.time_zone='city'
(e.g.:'London' or 'Bucharest' or 'Amsterdam' and so on).
It should work just fine. It worked for me.
In addition to the above answers you can also use .once
in a similar way to .output
. This outputs only the next query to the specified file, so that you don't have to follow with .output stdout
.
So in the above example
.mode csv
.headers on
.once test.csv
select * from tbl1;
A more recent solution is using the The PerformanceNavigation interface:
if(!!window.performance && window.performance.navigation.type === 2)
{
console.log('Reloading');
window.location.reload();
}
Where the value 2 means "The page was accessed by navigating into the history".

Angular initializes automatically upon
DOMContentLoaded
event or when the angular.js script is evaluated if at that time document.readyState is set to 'complete'. At this point Angular looks for the ng-app directive which designates your application root.
https://docs.angularjs.org/guide/bootstrap
This means that the controller code will run after the DOM is ready.
Thus it's just $scope.init()
.

Try running:
PATH=$PATH:~/npm/bin
and then do a test by running express
in the command line. This worked for me.
You can also zoom by using MKCoordinateRegion and setting its span latitude & longitude delta. Below is a quick reference and here is the iOS reference. It won't do anything fancy but should allow you to set zoom when it draws the map.
MKCoordinateRegion region;
region.center.latitude = {desired lat};
region.center.longitude = {desired lng};
region.span.latitudeDelta = 1;
region.span.longitudeDelta = 1;
mapView.region = region;
Edit 1:
MKCoordinateRegion region;
region.center.latitude = {desired lat};
region.center.longitude = {desired lng};
region.span.latitudeDelta = 1;
region.span.longitudeDelta = 1;
region = [mapView regionThatFits:region];
[mapView setRegion:region animated:TRUE];
You can get the column value in VB.net
Dim row As DataRow = fooTable.Rows(0)
Dim temp = Convert.ToString(row("ColumnName"))
And in C# you can use Jimmy's Answer, just be careful while converting it to ToString()
. It can throw null exception if the data is null
instead Use Convert.ToString(your_expression)
to avoid null exception reference
To use multiple files from node_modules in html, the best way I've found is to put them to an array and then loop on them to make them visible for web clients, for example to use filepond modules from node_modules:
const filePondModules = ['filepond-plugin-file-encode', 'filepond-plugin-image-preview', 'filepond-plugin-image-resize', 'filepond']
filePondModules.forEach(currentModule => {
let module_dir = require.resolve(currentModule)
.match(/.*\/node_modules\/[^/]+\//)[0];
app.use('/' + currentModule, express.static(module_dir + 'dist/'));
})
And then in the html (or layout) file, just call them like this :
<link rel="stylesheet" href="/filepond/filepond.css">
<link rel="stylesheet" href="/filepond-plugin-image-preview/filepond-plugin-image-preview.css">
...
<script src="/filepond-plugin-image-preview/filepond-plugin-image-preview.js" ></script>
<script src="/filepond-plugin-file-encode/filepond-plugin-file-encode.js"></script>
<script src="/filepond-plugin-image-resize/filepond-plugin-image-resize.js"></script>
<script src="/filepond/filepond.js"></script>
Warning: Use the below steps at your own risk. You may receive different results as indicated in the comments. Please exercise caution and have a full backup prior to doing this.
Below is a list of steps used to solve the issue:
Remove Docker (this won't delete images, containers, volumes, or customized configuration files):
sudo apt-get purge docker-engine
Remove the Docker apt key:
sudo apt-key del 58118E89F3A912897C070ADBF76221572C52609D
Delete the docker.list file:
sudo rm /etc/apt/sources.list.d/docker.list
Manually delete apt cache files:
sudo rm /var/lib/apt/lists/apt.dockerproject.org_repo_dists_ubuntu-xenial_*
Delete apt-transport-https and ca-certificates:
sudo apt-get purge apt-transport-https ca-certificates
Clean apt and perform autoremove:
sudo apt-get clean && sudo apt-get autoremove
Reboot Ubuntu:
sudo reboot
Run apt-get update:
sudo apt-get update
Install apt-transport-https and ca-certificates again:
sudo apt-get install apt-transport-https ca-certificates
Add the apt key:
> sudo apt-key adv \
--keyserver hkp://ha.pool.sks-keyservers.net:80 \
--recv-keys 58118E89F3A912897C070ADBF76221572C52609D
> echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" |
sudo tee /etc/apt/sources.list.d/docker.list
> sudo apt-get update
> sudo apt-get install docker-engine
Granted, there are plenty of variables and your results may vary. However, these steps cover as many areas as possible to ensure potential problem spots are scrubbed so that the likelihood of success is higher.
Update 7/6/2017
It appears newer versions of Docker are using a different installation process which should eliminate many of these problems. Be sure to check out https://docs.docker.com/engine/installation/linux/ubuntu/.
There is a packages.config file with the project, it contains the package details.
Also there is a .nuget folder which contains the NuGet.exe and NuGet.targets. if any one of the file is missing it will not restore the missing package and cause "are you missing a using directive or an assembly reference?" error
If you got node __dirname not defined
with node --experimental-modules
, you can do :
const __dirname = path.dirname(import.meta.url)
.replace(/^file:\/\/\//, '') // can be usefull
Because othe example, work only with current/pwd directory not other directory.
from IPython.display import Image
Image(filename =r'C:\user\path')
I've seen some solutions and some wont work because of the raw directory, when adding codes like the one above, just remember to add 'r' before the directory. this should avoid this kind of error: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
any of these should work
outf.write("%s" % num)
outf.write(str(num))
print >> outf, num
I would suggest the use of exists
instead of in
because in some scenarios that implies null values the behavior is different, so
CREATE TRIGGER sampleTrigger
ON database1.dbo.table1
FOR DELETE
AS
DELETE FROM database2.dbo.table2 childTable
WHERE bar = 4 AND exists (SELECT id FROM deleted where deleted.id = childTable.id)
GO
I was missing the MSVCR110.dll. Which I corrected. I could run php from the command line but not the web server. Then I clicked on php-cgi.exe and it gave me the answer. The php5.dll was missing (I downloaded the wrong copy). So for my 2012 IIS box I re-installed using php's x86 non thread safe zip.
"C:\Program Files\PuTTY\pscp.exe" -scp file.py server.com:
file.py
will be uploaded into your HOME
dir on remote server.
or when the remote server has a different user, use "C:\Program Files\PuTTY\pscp.exe" -l username -scp file.py server.com:
After connecting to the server pscp will ask for a password.
I was using salesforce apex classes with Eclipse Neon 3.3 for Java.
I found an option "define folding region" on right click in the editor, I selected the block of code i wanted to collapse and selected this property for that code. Now I am seeing + and - symbol to expand and collapse that block of code
You can use the fuser
command, like:
fuser file_name
You will receive a list of processes using the file.
You can use different flags with it, in order to receive a more detailed output.
You can find more info in the fuser's Wikipedia article, or in the man
pages.
public function unserializeKeySkills($string) {
$output = array();
$string = trim(preg_replace('/\s\s+/', ' ',$string));
$string = preg_replace_callback('!s:(\d+):"(.*?)";!', function($m) { return 's:'.strlen($m[2]).':"'.$m[2].'";'; }, utf8_encode( trim(preg_replace('/\s\s+/', ' ',$string)) ));
try {
$output = unserialize($string);
} catch (\Exception $e) {
\Log::error("unserialize Data : " .print_r($string,true));
}
return $output;
}
Suggest use Apache IOUtils.readLines for this. See link below.
http://commons.apache.org/proper/commons-io/apidocs/org/apache/commons/io/IOUtils.html
No you cannot get the MAC address in JavaScript, mainly because the MAC address uniquely identifies the running computer so it would be a security vulnerability.
Now if all you need is a unique identifier, I suggest you create one yourself using some cryptographic algorithm and store it in a cookie.
If you really need to know the MAC address of the computer AND you are developing for internal applications, then I suggest you use an external component to do that: ActiveX for IE, XPCOM for Firefox (installed as an extension).
Try this regular expression:
\w*Id\b
\w*
allows word characters in front of Id
and the \b
ensures that Id
is at the end of the word (\b
is word boundary assertion).
If you need to add two strings you have to use the '+' operator
hence
msg['Subject'] = 'your string' + sys.argv[1]
and also you have to import sys in the beginning
as
import sys
msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]
To get mod_rewrite to work for me in Apache 2.4, I had to add the "Require all granted" line below.
<Directory /var/www>
# Required if running apache > 2.4
Require all granted
RewriteEngine on
RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L]
</Directory>
supposedly a similar requirement exists for Apache 2.2 as well, if you're using that:
<Directory /var/www>
# Required if running apache 2.2
Order allow,deny
Allow from all
RewriteEngine on
RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L]
</Directory>
Note that an ErrorDocument 404
directive can sometimes override these things as well, so if it's not working try commenting out your ErrorDocument directive and see if it works. The above example can be used to ensure a site isn't served from cache by including a subfolder in the path, though the files reside at the root of the server.
onBackPressed()
is supported since: API Level 5
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK)) {
onBackPressed();
}
}
@Override
public void onBackPressed() {
//this is only needed if you have specific things
//that you want to do when the user presses the back button.
/* your specific things...*/
super.onBackPressed();
}
res = request.GET['paymentid']
will raise a KeyError
if paymentid
is not in the GET data.
Your sample php code checks to see if paymentid
is in the POST data, and sets $payID
to '' otherwise:
$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''
The equivalent in python is to use the get()
method with a default argument:
payment_id = request.POST.get('payment_id', '')
while debugging, this is what I see in the
response.GET: <QueryDict: {}>
,request.POST: <QueryDict: {}>
It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.
Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.
Also, if you don't mind using numpy arrays (or in fact already are dealing with numpy arrays...), here is another nice solution:
people = ['Jim', 'Pam', 'Micheal', 'Dwight']
ages = [27, 25, 4, 9]
import numpy
people = numpy.array(people)
ages = numpy.array(ages)
inds = ages.argsort()
sortedPeople = people[inds]
I found it here: http://scienceoss.com/sort-one-list-by-another-list/
For kotlin user's
fun Activity.displayMetrics(): DisplayMetrics {
val displayMetrics = DisplayMetrics()
windowManager.defaultDisplay.getMetrics(displayMetrics)
return displayMetrics
}
And in Activity you could use it like
resources.displayMetrics.let { displayMetrics ->
val height = displayMetrics.heightPixels
val width = displayMetrics.widthPixels
}
Or in fragment
activity?.displayMetrics()?.run {
val height = heightPixels
val width = widthPixels
}
I was testing out the speed of the functions, and I found consistently that this solution that I had written was much faster than match
ing. We check the new length of the string as compared to the previous length.
const lines = str.length - str.replace(/\n/g, "").length+1;
let str = `Line1
Line2
Line3`;
console.time("LinesTimer")
console.log("Lines: ",str.length - str.replace(/\n/g, "").length+1);
console.timeEnd("LinesTimer")

You could try something like
<form name="message" method="post">
<section>
<div>
<label for="name">Name</label>
<input id="name" type="text" value="" name="name">
</div>
<div>
<label for="email">Email</label>
<input id="email" type="text" value="" name="email">
</div>
</section>
<section>
<div>
<label for="subject">Subject</label>
<input id="subject" type="text" value="" name="subject">
</div>
<div class="full">
<label for="message">Message</label>
<input id="message" type="text" value="" name="message">
</div>
</section>
</form>
and then css it like
form { width: 400px; }
form section div { float: left; }
form section div.full { clear: both; }
form section div label { display: block; }
I believe this answer is better:
https://unix.stackexchange.com/questions/12593/how-to-remove-all-the-files-in-a-directory
If your top-level directory is called
images
, then runrm -r images/*
. This uses the shell glob operator*
to runrm -r
on every file or directory within images.
basically you go up one level, and then say delete everything inside X directory. This way you are still specifying what folder should have its content deleted, which is safer than just saying 'delete everything here", while preserving the original folder, (which sometimes you want to because you aren't allowed or just don't want to modify the folder's existing permissions)
In VS code 'User Settings', you can edit visible colours using the following tags(this is a sample and there are much more tags),
"workbench.colorCustomizations": {
"list.inactiveSelectionBackground": "#C5DEF0",
"sideBar.background": "#F8F6F6",
"sideBar.foreground": "#000000",
"editor.background": "#FFFFFF",
"editor.foreground": "#000000",
"sideBarSectionHeader.background": "#CAC9C9",
"sideBarSectionHeader.foreground": "#000000",
"activityBar.border": "#FFFFFF",
"statusBar.background": "#102F97",
"scrollbarSlider.activeBackground": "#77D4CB",
"scrollbarSlider.hoverBackground": "#8CE6DA",
"badge.background": "#81CA91"}
If you want to edit some C++ color tokens, use the following tag,
"editor.tokenColorCustomizations": {
"numbers": "#2247EB",
"comments": "#6D929C",
"functions": "#0D7C28"
}
You use it when you have lots of options to deal with. Think about things like jmock:
m.expects(once())
.method("testMethod")
.with(eq(1), eq(2))
.returns("someResponse");
It feels a lot more natural and is...possible.
There's also xml building, string building and many other things. Imagine if java.util.Map
had put as a builder. You could do stuff like this:
Map<String, Integer> m = new HashMap<String, Integer>()
.put("a", 1)
.put("b", 2)
.put("c", 3);
Updated @Hussein solution with preview height that will adapt to the paragraph number of lines.
So with this bit of code : - You can choose the number of lines you want to show in preview, it will works for all screen sizes, even if font-size is responsive. - There is no need to add classes or back-end editing to separate preview from whole content.
http://jsfiddle.net/7Vv8u/5816/
var h = $('div')[0].scrollHeight;
divLineHeight = parseInt($('div').css('line-height'));
divPaddingTop = parseInt($('div').css('padding-top'));
lineToShow = 2;
divPreviewHeight = divLineHeight*lineToShow - divPaddingTop;
$('div').css('height', divPreviewHeight );
$('#more').click(function(e) {
e.stopPropagation();
$('div').animate({
'height': h
})
});
$(document).click(function() {
$('div').animate({
'height': divPreviewHeight
})
})
Just simply right A
{{ date('h:i A', strtotime($varname->created_at))}}
Basically, there are two important differences between + and the concat
method.
If you are using the concat method then you would only be able to concatenate strings while in case of the + operator, you can also concatenate the string with any data type.
For Example:
String s = 10 + "Hello";
In this case, the output should be 10Hello.
String s = "I";
String s1 = s.concat("am").concat("good").concat("boy");
System.out.println(s1);
In the above case you have to provide two strings mandatory.
The second and main difference between + and concat is that:
Case 1: Suppose I concat the same strings with concat operator in this way
String s="I";
String s1=s.concat("am").concat("good").concat("boy");
System.out.println(s1);
In this case total number of objects created in the pool are 7 like this:
I
am
good
boy
Iam
Iamgood
Iamgoodboy
Case 2:
Now I am going to concatinate the same strings via + operator
String s="I"+"am"+"good"+"boy";
System.out.println(s);
In the above case total number of objects created are only 5.
Actually when we concatinate the strings via + operator then it maintains a StringBuffer class to perform the same task as follows:-
StringBuffer sb = new StringBuffer("I");
sb.append("am");
sb.append("good");
sb.append("boy");
System.out.println(sb);
In this way it will create only five objects.
So guys these are the basic differences between + and the concat method. Enjoy :)
