use json library
import json
json.dumps(list)
by the way, you might consider changing variable list to another name, list
is the builtin function for a list creation, you may get some unexpected behaviours or some buggy code if you don't change the variable name.
You can get at the data values like this:
string json = @"
[
{ ""General"" : ""At this time we do not have any frequent support requests."" },
{ ""Support"" : ""For support inquires, please see our support page."" }
]";
JArray a = JArray.Parse(json);
foreach (JObject o in a.Children<JObject>())
{
foreach (JProperty p in o.Properties())
{
string name = p.Name;
string value = (string)p.Value;
Console.WriteLine(name + " -- " + value);
}
}

Even though this is bit late response, may be helpful for someone. Look like you have used pluginManagement. If you use pluginManagement , it will not pick the plug-in execution.
It should be under

The answer by Nick Mitchinson is for Bootstrap version 2.
If you are using Bootstrap version 3, then forms have changed a bit. For bootstrap 3, use the following instead:
<div class="form-horizontal">
<div class="form-group">
<div class="col-md-6">
<textarea class="form-control" rows="3" placeholder="What's up?" required></textarea>
</div>
</div>
</div>
Where, col-md-6 will target medium sized devices. You can add col-xs-6 etc to target smaller devices.
Listen to @milkplusvellocet, I'd recommend you to implement the Comparable interface to your class as well.
Just contributing to the answers of others:
String.compareTo()
will tell you how different a string is from another.
e.g. System.out.println( "Test".compareTo("Tesu") );
will print -1
and System.out.println( "Test".compareTo("Tesa") );
will print 19
and nerdy and geeky one-line solution to this task would be:
return this.lastName.equals(s.getLastName()) ? this.lastName.compareTo(s.getLastName()) : this.firstName.compareTo(s.getFirstName());
Explanation:
this.lastName.equals(s.getLastName())
checks whether lastnames are the same or not
this.lastName.compareTo(s.getLastName())
if yes, then returns comparison of last name.
this.firstName.compareTo(s.getFirstName())
if not, returns the comparison of first name.
Raw arrays aren't resizable in C++.
You should be using something like a Vector class which does allow resizing..
std::vector
allows you to resize it as well as allowing dynamic resizing when you add elements (often making the manual resizing unnecessary for adding).
Source location should be the URL (relative to the css file or full web location), not a file system full path, for example:
background: url("http://localhost/media/css/static/img/sprites/buttons-v3-10.png");
background: url("static/img/sprites/buttons-v3-10.png");
Alternatively, you can try to use file:///
protocol prefix.
Just like @Thomas said, the element you want to change must implement INotifyPropertyChanged. But, datasource is also important. It has to be BindingList, which you can create easily from List.
Here is my example - data source is at first DataTable, which I transfer to List and then create BindingList. Then I create BindingSource and use BindingList as DataSource from BindingSource. At last, DataSource from DataGridView uses this BindingSource.
sp_Select_PersonTableAdapter adapter = new sp_Select_PersonTableAdapter();
DataTable tbl = new DataTable();
tbl.Merge(adapter.GetData());
List<Person> list = tbl.AsEnumerable().Select(x => new Person
{
Id = (Int32) (x["Id"]),
Ime = (string) (x["Name"] ?? ""),
Priimek = (string) (x["LastName"] ?? "")
}).ToList();
BindingList<Person> bindingList = new BindingList<Person>(list);
BindingSource bindingSource = new BindingSource();
bindingSource.DataSource = bindingList;
dgvPerson.DataSource = bindingSource;
What is also very important: each class's member setter must call OnPropertyChanged(). Without that, it won't work. So, my class looks like this:
public class Person : INotifyPropertyChanged
{
private int _id;
private string _name;
private string _lastName;
public int Id
{
get { return _id; }
set
{
if (value != _id)
{
_id = value;
OnPropertyChanged();
}
}
}
public string Name
{
get { return _name; }
set
{
if (value != _name)
{
_name = value;
OnPropertyChanged();
}
}
}
public string LastName
{
get { return _lastName; }
set
{
if (value != _lastName)
{
_lastName= value;
OnPropertyChanged();
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
[NotifyPropertyChangedInvocator]
protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
}
}

As Boltclock states in his answer to Selecting and manipulating CSS pseudo-elements such as ::before and ::after using jQuery
Although they are rendered by browsers through CSS as if they were like other real DOM elements, pseudo-elements themselves are not part of the DOM, and thus you can't select and manipulate them with jQuery.
Might just be best to set the style with jQuery instead of using the pseudo CSS selector.
The plugin developed by @dubrox is very lightweight and works almost identical to jQuery UI. My requirement was to have the ability to restrict the number of dates selected.
Intuitively, the maxPicks
property seems to have been provided for this purpose, but it doesn't work unfortunately.
For those of you looking for this fix, here it is:
First up, you need to patch jquery.ui.multidatespicker.js
. I have submitted a pull request on github. You can use that until dubrox merges it with the master or comes up with a fix of his own.
Usage is really straightforward. The below code causes the date picker to not select any dates once the specified number of dates (maxPicks
) has been already selected. If you unselect any previously selected date, it will let you select again until you reach the limit once again.
$("#mydatefield").multiDatesPicker({maxPicks: 3});
SWIFT 4 with extension
set:
// set button label for all states
extension UIButton {
public func setAllStatesTitle(_ newTitle: String){
self.setTitle(newTitle, for: .normal)
self.setTitle(newTitle, for: .selected)
self.setTitle(newTitle, for: .disabled)
}
}
and use:
yourBtn.setAllStatesTitle("btn title")
Using Linq to find the object you can do:
var obj = myList.FirstOrDefault(x => x.MyProperty == myValue);
if (obj != null) obj.OtherProperty = newValue;
But in this case you might want to save the List into a Dictionary and use this instead:
// ... define after getting the List/Enumerable/whatever
var dict = myList.ToDictionary(x => x.MyProperty);
// ... somewhere in code
MyObject found;
if (dict.TryGetValue(myValue, out found)) found.OtherProperty = newValue;
Use the map
method:
var a = [1, 2, 3]_x000D_
var b = ['a', 'b', 'c']_x000D_
_x000D_
var c = a.map(function(e, i) {_x000D_
return [e, b[i]];_x000D_
});_x000D_
_x000D_
console.log(c)
_x000D_
When you say you tried to use OR, how exactly did you try and use it? In your case, what you will need to do would be something like so:
String newStr4 = strr.split("2012")[0];
if(newStr4.startsWith("Mon") || newStr4.startsWith("Tues")...)
str4.add(newStr4);
I feel I need to clarify one very important thing, for others (like my co-worker) who came across this thread and got the wrong information.
The answer given ("Try decimal(9,2) or decimal(10,2) or whatever.") is correct, but the reason ("increase the number of digits before the decimal") is wrong.
decimal(p,s) and numeric(p,s) both specify a Precision and a Scale. The "precision" is not the number of digits to the left of the decimal, but instead is the total precision of the number.
For example: decimal(2,1) covers 0.0 to 9.9, because the precision is 2 digits (00 to 99) and the scale is 1. decimal(4,1) covers 000.0 to 999.9 decimal(4,2) covers 00.00 to 99.99 decimal(4,3) covers 0.000 to 9.999

Don't just hastily pick the first import strategy that works for you or else you'll have to rewrite the codebase later on when you find it doesn't meet your needs.
I'll start out explaining the easiest example #1, then I'll move toward the most professional and robust example #7
Example 1, Import a python module with python interpreter:
Put this in /home/el/foo/fox.py:
def what_does_the_fox_say():
print("vixens cry")
Get into the python interpreter:
el@apollo:/home/el/foo$ python
Python 2.7.3 (default, Sep 26 2013, 20:03:06)
>>> import fox
>>> fox.what_does_the_fox_say()
vixens cry
>>>
You imported fox through the python interpreter, invoked the python function what_does_the_fox_say()
from within fox.py.
Example 2, Use execfile
or (exec
in Python 3) in a script to execute the other python file in place:
Put this in /home/el/foo2/mylib.py:
def moobar():
print("hi")
Put this in /home/el/foo2/main.py:
execfile("/home/el/foo2/mylib.py")
moobar()
run the file:
el@apollo:/home/el/foo$ python main.py
hi
The function moobar was imported from mylib.py and made available in main.py
Example 3, Use from ... import ... functionality:
Put this in /home/el/foo3/chekov.py:
def question():
print "where are the nuclear wessels?"
Put this in /home/el/foo3/main.py:
from chekov import question
question()
Run it like this:
el@apollo:/home/el/foo3$ python main.py
where are the nuclear wessels?
If you defined other functions in chekov.py, they would not be available unless you import *
Example 4, Import riaa.py if it's in a different file location from where it is imported
Put this in /home/el/foo4/stuff/riaa.py:
def watchout():
print "computers are transforming into a noose and a yoke for humans"
Put this in /home/el/foo4/main.py:
import sys
import os
sys.path.append(os.path.abspath("/home/el/foo4/stuff"))
from riaa import *
watchout()
Run it:
el@apollo:/home/el/foo4$ python main.py
computers are transforming into a noose and a yoke for humans
That imports everything in the foreign file from a different directory.
Example 5, use os.system("python yourfile.py")
import os
os.system("python yourfile.py")
Example 6, import your file via piggybacking the python startuphook:
Update: This example used to work for both python2 and 3, but now only works for python2. python3 got rid of this user startuphook feature set because it was abused by low-skill python library writers, using it to impolitely inject their code into the global namespace, before all user-defined programs. If you want this to work for python3, you'll have to get more creative. If I tell you how to do it, python developers will disable that feature set as well, so you're on your own.
See: https://docs.python.org/2/library/user.html
Put this code into your home directory in ~/.pythonrc.py
class secretclass:
def secretmessage(cls, myarg):
return myarg + " is if.. up in the sky, the sky"
secretmessage = classmethod( secretmessage )
def skycake(cls):
return "cookie and sky pie people can't go up and "
skycake = classmethod( skycake )
Put this code into your main.py (can be anywhere):
import user
msg = "The only way skycake tates good"
msg = user.secretclass.secretmessage(msg)
msg += user.secretclass.skycake()
print(msg + " have the sky pie! SKYCAKE!")
Run it, you should get this:
$ python main.py
The only way skycake tates good is if.. up in the sky,
the skycookie and sky pie people can't go up and have the sky pie!
SKYCAKE!
If you get an error here: ModuleNotFoundError: No module named 'user'
then it means you're using python3, startuphooks are disabled there by default.

Example 7, Most Robust: Import files in python with the bare import command:
/home/el/foo5/
/home/el/foo5/herp
Make an empty file named __init__.py
under herp:
el@apollo:/home/el/foo5/herp$ touch __init__.py
el@apollo:/home/el/foo5/herp$ ls
__init__.py
Make a new directory /home/el/foo5/herp/derp
Under derp, make another __init__.py
file:
el@apollo:/home/el/foo5/herp/derp$ touch __init__.py
el@apollo:/home/el/foo5/herp/derp$ ls
__init__.py
Under /home/el/foo5/herp/derp make a new file called yolo.py
Put this in there:
def skycake():
print "SkyCake evolves to stay just beyond the cognitive reach of " +
"the bulk of men. SKYCAKE!!"
The moment of truth, Make the new file /home/el/foo5/main.py
, put this in there;
from herp.derp.yolo import skycake
skycake()
Run it:
el@apollo:/home/el/foo5$ python main.py
SkyCake evolves to stay just beyond the cognitive reach of the bulk
of men. SKYCAKE!!
The empty __init__.py
file communicates to the python interpreter that the developer intends this directory to be an importable package.

For readability, I'd go with
char * s = malloc(snprintf(NULL, 0, "%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);
If your platform supports GNU extensions, you could also use asprintf()
:
char * s = NULL;
asprintf(&s, "%s %s", first, second);
If you're stuck with the MS C Runtime, you have to use _scprintf()
to determine the length of the resulting string:
char * s = malloc(_scprintf("%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);
The following will most likely be the fastest solution:
size_t len1 = strlen(first);
size_t len2 = strlen(second);
char * s = malloc(len1 + len2 + 2);
memcpy(s, first, len1);
s[len1] = ' ';
memcpy(s + len1 + 1, second, len2 + 1); // includes terminating null
If you have Oracle 10g, REGEXP_REPLACE is pretty flexible.
Using the following string as a test:
chr(9) || 'Q qwer' || chr(9) || chr(10) ||
chr(13) || 'qwerqwer qwerty' || chr(9) ||
chr(10) || chr(13)
The [[:space:]]
will remove all whitespace, and the ([[:cntrl:]])|(^\t)
regexp will remove non-printing characters and tabs.
select
tester,
regexp_replace(tester, '(^[[:space:]]+)|([[:space:]]+$)',null)
regexp_tester_1,
regexp_replace(tester, '(^[[:cntrl:]^\t]+)|([[:cntrl:]^\t]+$)',null)
regexp_tester_2
from
(
select
chr(9) || 'Q qwer' || chr(9) || chr(10) ||
chr(13) || 'qwerqwer qwerty' || chr(9) ||
chr(10) || chr(13) tester
from
dual
)
Returning:
Qqwerqwerqwerqwerty
"Q qwerqwerqwer qwerty
"Hope this is of some use.
No unnecessary complication required...
function sortMapByValue(map)
{
var tupleArray = [];
for (var key in map) tupleArray.push([key, map[key]]);
tupleArray.sort(function (a, b) { return a[1] - b[1] });
return tupleArray;
}
The @Qualifier
annotation is used to resolve the autowiring conflict, when there are multiple beans of same type.
The @Qualifier
annotation can be used on any class annotated with @Component
or on methods annotated with @Bean
. This annotation can also be applied on constructor arguments or method parameters.
Ex:-
public interface Vehicle {
public void start();
public void stop();
}
There are two beans, Car and Bike implements Vehicle interface
@Component(value="car")
public class Car implements Vehicle {
@Override
public void start() {
System.out.println("Car started");
}
@Override
public void stop() {
System.out.println("Car stopped");
}
}
@Component(value="bike")
public class Bike implements Vehicle {
@Override
public void start() {
System.out.println("Bike started");
}
@Override
public void stop() {
System.out.println("Bike stopped");
}
}
Injecting Bike bean in VehicleService using @Autowired
with @Qualifier
annotation. If you didn't use @Qualifier
, it will throw NoUniqueBeanDefinitionException.
@Component
public class VehicleService {
@Autowired
@Qualifier("bike")
private Vehicle vehicle;
public void service() {
vehicle.start();
vehicle.stop();
}
}
Reference:- @Qualifier annotation example
If you prefer passing the arguments in a key-value pair you can use something like this:
@echo off
setlocal enableDelayedExpansion
::::: asigning arguments as a key-value pairs:::::::::::::
set counter=0
for %%# in (%*) do (
set /a counter=counter+1
set /a even=counter%%2
if !even! == 0 (
echo setting !prev! to %%#
set "!prev!=%%~#"
)
set "prev=%%~#"
)
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
:: showing the assignments
echo %one% %two% %three% %four% %five%
endlocal
And an example :
c:>argumentsDemo.bat one 1 "two" 2 three 3 four 4 "five" 5
1 2 3 4 5
You can also set some environment variables in advance. It can be done by setting them in the console or setting them from my computer:
@echo off
if defined variable1 (
echo %variable1%
)
if defined variable2 (
echo %variable2%
)
and calling it like:
c:\>set variable1=1
c:\>set variable2=2
c:\>argumentsTest.bat
1
2
You can also point to a file where the needed values are preset. If this is the script:
@echo off
setlocal
::::::::::
set "VALUES_FILE=E:\scripts\values.txt"
:::::::::::
for /f "usebackq eol=: tokens=* delims=" %%# in ("%VALUES_FILE%") do set "%%#"
echo %key1% %key2% %some_other_key%
endlocal
and values file is this:
:::: use EOL=: in the FOR loop to use it as a comment
key1=value1
key2=value2
:::: do not left spaces arround the =
:::: or at the begining of the line
some_other_key=something else
and_one_more=more
the output of calling it will be:
value1 value2 something else
Of course you can combine all approaches. Check also arguments syntax , shift
I had similar issue, my code was:
function RadioInput(props) {
return (
<div className="form-check form-check-inline">
<input className="form-check-input" type="radio" name="inlineRadioOptions" id={props.id} onClick={props.onClick} value={props.label}></input>
<label className="form-check-label" htmlFor={props.id}>{props.label}</label>
</div>
);
}
class ScheduleType extends React.Component
{
renderRadioInput(id,label)
{
id = "inlineRadio"+id;
return(
<RadioInput
id = {id}
label = {label}
onClick = {this.props.onClick}
/>
);
}
Where it should be
onClick = {() => this.props.onClick()}
in RenderRadioInput
It fixed the issue for me.
If what you're trying to do is disable an a link, there is no option to do this. I think you can find an answer that will work for you in this question here.
One option here is to use
<a href="/" onclick="return false;">123n</a>
Using ripgrep's replace option, it is possible to change the output to a capture group:
rg --only-matching --replace '$1' '(\d+) rofl'
--only-matching
or -o
outputs only the part that matches instead of the whole line.--replace '$1'
or -r
replaces the output by the first capture group.Installing Yarn for Ubuntu 16.04 (not sure if this will be the same as 14.04 as it's slightly different than zappee's answer for 17.04)

There's also one important tricky treat of ".PHONY" - when a physical target depends on phony target that depends on another physical target:
TARGET1 -> PHONY_FORWARDER1 -> PHONY_FORWARDER2 -> TARGET2
You'd simply expect that if you updated TARGET2, then TARGET1 should be considered stale against TARGET1, so TARGET1 should be rebuild. And it really works this way.
The tricky part is when TARGET2 isn't stale against TARGET1 - in which case you should expect that TARGET1 shouldn't be rebuild.
This surprisingly doesn't work because: the phony target was run anyway (as phony targets normally do), which means that the phony target was considered updated. And because of that TARGET1 is considered stale against the phony target.
Consider:
all: fileall
fileall: file2 filefwd
echo file2 file1 >fileall
file2: file2.src
echo file2.src >file2
file1: file1.src
echo file1.src >file1
echo file1.src >>file1
.PHONY: filefwd
.PHONY: filefwd2
filefwd: filefwd2
filefwd2: file1
@echo "Produced target file1"
prepare:
echo "Some text 1" >> file1.src
echo "Some text 2" >> file2.src
You can play around with this:
You can see that fileall depends on file1 indirectly through a phony target - but it always gets rebuilt due to this dependency. If you change the dependency in fileall
from filefwd
to file
, now fileall
does not get rebuilt every time, but only when any of dependent targets is stale against it as a file.
Change it to this:
var email = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
This is a regular expression literal that is passed the i
flag which means to be case insensitive.
Keep in mind that email address validation is hard (there is a 4 or 5 page regular expression at the end of Mastering Regular Expressions demonstrating this) and your expression certainly will not capture all valid e-mail addresses.
I had the same issue of WebMvcConfigurerAdapter being deprecated. When I searched for examples, I hardly found any implemented code. Here is a piece of working code.
create a class that extends HandlerInterceptorAdapter
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import me.rajnarayanan.datatest.DataTestApplication;
@Component
public class EmployeeInterceptor extends HandlerInterceptorAdapter {
private static final Logger logger = LoggerFactory.getLogger(DataTestApplication.class);
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
String x = request.getMethod();
logger.info(x + "intercepted");
return true;
}
}
then Implement WebMvcConfigurer interface

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import me.rajnarayanan.datatest.interceptor.EmployeeInterceptor;
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
@Autowired

Try that
First place
global $var;
$var = 'value';
Second place
global $var;
if (isset($_POST['save_exit']))
{
echo $var;
}
Or if you want to be more explicit you can use the globals array:
$GLOBALS['var'] = 'test';
// after that
echo $GLOBALS['var'];
And here is third options which has nothing to do with PHP global that is due to the lack of clarity and information in the question. So if you have form in HTML and you want to pass "variable"/value to another PHP script you have to do the following:
HTML form
<form action="script.php" method="post">
<input type="text" value="<?php echo $var?>" name="var" />
<input type="submit" value="Send" />
</form>
PHP script ("script.php")
<?php
$var = $_POST['var'];
echo $var;
?>
Yes You Can!
I worked on a project that did that (see comment). Unfortunately no code samples from that one, but googling revealed these:
How you can integrate data from several Web services using Excel and VBA
STEP BY STEP: Consuming Web Services through VBA (Excel or Word)
In Java, you can have just one public static void main(String[] args)
per class. Which mean, if your program has multiple classes, each class can have public static void main(String[] args)
. See JLS for details.
You can use getString
String name = jsonObject.getString("name");
// it will throws exception if the key you specify doesn't exist
or optString
String name = jsonObject.optString("name");
// it will returns the empty string ("") if the key you specify doesn't exist
C++14 brings generic lambdas. Meaning we can use std::for_each very easily:
std::map<int, int> myMap{{1, 2}, {3, 4}, {5, 6}, {7, 8}};
std::for_each(myMap.begin(), myMap.end(), [](const auto &myMapPair) {
std::cout << "first " << myMapPair.first << " second "
<< myMapPair.second << std::endl;
});
I think std::for_each is sometimes better suited than a simple range based for loop. For example when you only want to loop through a subset of a map.
To expand upon Mr. Eels comment, you can do it like this:
File file = new File("C:\\A.txt");
FileWriter writer;
try {
writer = new FileWriter(file, true);
PrintWriter printer = new PrintWriter(writer);
printer.append("Sue");
printer.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Don't say we ain't good to ya!
Iterate over the codes
array using a loop, asking for each of the elements if it's equals()
to usercode
. If one element is equal, you can stop and handle that case. If none of the elements is equal to usercode
, then do the appropriate to handle that case. In pseudocode:
found = false
foreach element in array:
if element.equals(usercode):
found = true
break
if found:
print "I found it!"
else:
print "I didn't find it"

In my case, the project was a Maven, I had JDK 1.8.0, Eclipse : Kepler, and I installed the M2Eclipse plugin from Eclipse Marketplace.
Changing compiler level didn't help.
Finally I used latest version of eclipse (Luna), compiler level 1.7, same M2Eclipse plugin and problem was solved.
go path could be every where you want just create a directory and set global path variable in the name of GOPATH to your environment.
mkdir ~/go
export GOPATH=~/go

If you are using ZSH and have Android Studio 1.3:
1. Open .zshrc file (Located in your home directory, file is hidden so make sure you can see hidden files)
2. Add this line at the end: alias adb="/Users/kamil/Library/Android/sdk/platform-tools/adb"
3. Quit terminal
4. Open terminal and type in adb devices
5. If it worked it will give you list of all connected devices
This method doesn't use any transform. So it doesn't have a problem with the output becoming blurry.

Use the :not
pseudo-class to exclude the classes you don't want the hover to apply to:

.test:not(.nohover):hover {

}
This does what you want in one css rule!
Late answer, but you can take advantage of the fact that you can deserialize multiple objects from one JSON string, as long as the objects don't share any common property names,
public async Task<HttpResponseMessage> Post(HttpRequestMessage request)
{
var jsonString = await request.Content.ReadAsStringAsync();
var content = JsonConvert.DeserializeObject<Content >(jsonString);
var config = JsonConvert.DeserializeObject<Config>(jsonString);
}
As usual in Angular, you can rely on dependency injection:
import { DatePipe } from '@angular/common';
class MyService {
constructor(private datePipe: DatePipe) {}
transformDate(date) {
return this.datePipe.transform(date, 'yyyy-MM-dd');
}
}
Add DatePipe
to your providers list in your module; if you forget to do this you'll get an error no provider for DatePipe
:
providers: [DatePipe,...]
Update Angular 6: Angular 6 now offers pretty much every formatting functions used by the pipes publicly. For example, you can now use the formatDate
function directly.
import { formatDate } from '@angular/common';
class MyService {
constructor(@Inject(LOCALE_ID) private locale: string) {}
transformDate(date) {
return formatDate(date, 'yyyy-MM-dd', this.locale);
}
}
Before Angular 5: Be warned though that the DatePipe
was relying on the Intl API until version 5, which is not supported by all browsers (check the compatibility table).
If you're using older Angular versions, you should add the Intl
polyfill to your project to avoid any problem.

Since you want to hide your column you can always hide the column in preRender event of the gridview . This helps you with reducing one operation for every rowdatabound event per row . You will need only one operation for prerender event .
protected void gvVoucherList_PreRender(object sender, EventArgs e)
{
try
{
int RoleID = Convert.ToInt32(Session["RoleID"]);
switch (RoleID)
{
case 6: gvVoucherList.Columns[11].Visible = false;
break;
case 1: gvVoucherList.Columns[10].Visible = false;
break;
}
if(hideActionColumn == "ActionSM")
{
gvVoucherList.Columns[10].Visible = false;
hideActionColumn = string.Empty;
}
}
catch (Exception Ex)
{
}
}
You have the pipe the other way around and you need to echo the query, like this:
myvariable=$(echo "SELECT A, B, C FROM table_a" | mysql db -u $user -p $password)
Another alternative is to use only the mysql client, like this
myvariable=$(mysql db -u $user -p $password -se "SELECT A, B, C FROM table_a")
(-s
is required to avoid the ASCII-art)
Now, BASH isn't the most appropriate language to handle this type of scenarios, especially handling strings and splitting SQL results and the like. You have to work a lot to get things that would be very, very simple in Perl, Python or PHP.
For example, how will you get each of A, B and C on their own variable? It's certainly doable, but if you do not understand pipes and echo (very basic shell stuff), it will not be an easy task for you to do, so if at all possible I'd use a better suited language.
I've got the error in an other context. So my solution might be useful to others who stumple upon the question:
The problem: I've copied the local repository to another computer, which has no connection to a special repository. So maven tried to check the artifacts against the invalid repository.
My solution: Remove the _maven.repositories files.
Note that Visual C++ compilers are removed when you upgrade Visual Studio 2010 Professional or Visual Studio 2010 Express to Visual Studio 2010 SP1 if Windows SDK v7.1 is installed.

I found SchemaSpy quite good - you have to run the script every time schema changes but it is not so big deal.

Is better to use a validation to support versions pre Android N, example:

imageUri = Uri.parse(filepath);
} else{
imageUri = Uri.fromFile(new File(filepath));
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
ImageView.setImageURI(Uri.parse(new File("/sdcard/cats.jpg").toString()));
} else{
ImageView.setImageURI(Uri.fromFile(new File("/sdcard/cats.jpg")));
}
Write the JSON object to the response object's output stream.
You should also set the content type as follows, which will specify what you are returning:
response.setContentType("application/json");
// Get the printwriter object from response to write the required json object to the output stream
PrintWriter out = response.getWriter();
// Assuming your json object is **jsonObject**, perform the following, it will return your json object
out.print(jsonObject);
out.flush();
None of the above worked so with a bit of tinkering here's code that did for me
Intent i = new Intent(Intent.ACTION_DIAL);
String p = "tel:" + getString(R.string.phone_number);
i.setData(Uri.parse(p));
startActivity(i);

I've run some TCP/IP client/server connection tests in the past on Windows 2003 Server and managed more than 70,000 connections on a reasonably low spec VM. (see here for details: http://www.lenholgate.com/blog/2005/10/the-64000-connection-question.html). I would be extremely surprised if Windows 2008 Server is limited to less than 2003 Server and, IMHO, the posting that Cloud links to is too vague to be much use. This kind of question comes up a lot, I blogged about why I don't really think that it's something that you should actually worry about here: http://www.serverframework.com/asynchronousevents/2010/12/one-million-tcp-connections.html.
Personally I'd test it and see. Even if there is no inherent limit in the Windows 2008 Server version that you intend to use there will still be practical limits based on memory, processor speed and server design.
If you want to run some 'generic' tests you can use my multi-client connection test and the associated echo server. Detailed here: http://www.lenholgate.com/blog/2005/11/windows-tcpip-server-performance.html and here: http://www.lenholgate.com/blog/2005/11/simple-echo-servers.html. These are what I used to run my own tests for my server framework and these are what allowed me to create 70,000 active connections on a Windows 2003 Server VM with 760MB of memory.
Edited to add details from the comment below...
If you're already thinking of multiple servers I'd take the following approach.
Use the free tools that I link
to and prove to yourself that you
can create a reasonable number of
connections onto your target OS
(beware of the Windows limits on
dynamic ports which may cause your
client connections to fail, search
for MAX_USER_PORT
).
during development regularly test your actual server with test clients that can create connections and actually 'do something' on the server. This will help to prevent you building the server in ways that restrict its scalability. See here: http://www.serverframework.com/asynchronousevents/2010/10/how-to-support-10000-or-more-concurrent-tcp-connections-part-2-perf-tests-from-day-0.html
Or you could nest the data in cols 4 and 5 into a single row with tidyr
:
library(tidyr)
df %>% nest(V4:V5)
# A tibble: 1 × 4
# V1 V2 V3 data
# <fctr> <int> <int> <list>
#1 platform_external_dbus 202 16 <tibble [5 × 2]>
The col 2 and 3 duplicates are now removed for statistical analysis, but you have kept the col 4 and 5 data in a tibble and can go back to the original data frame at any point with unnest()
.
Up to C# 7.0, there was no way to do this short of defining your own type.
I had a look at the above answers and honestly none of them I find satisfactory. What you want to do is essentially mimic the Perl split functionality. Why Java doesn't allow this and have a join() method somewhere is beyond me but I digress. You don't even need a class for this really. Its just a function. Run this sample program:
Some of the earlier answers have excessive null-checking, which I recently wrote a response to a question here:
https://stackoverflow.com/users/18393/cletus
Anyway, the code:
public class Split {
public static List<String> split(String s, String pattern) {
assert s != null;
assert pattern != null;
return split(s, Pattern.compile(pattern));
}
public static List<String> split(String s, Pattern pattern) {
assert s != null;
assert pattern != null;
Matcher m = pattern.matcher(s);
List<String> ret = new ArrayList<String>();
int start = 0;
while (m.find()) {
ret.add(s.substring(start, m.start()));
ret.add(m.group());
start = m.end();
}
ret.add(start >= s.length() ? "" : s.substring(start));
return ret;
}
private static void testSplit(String s, String pattern) {
System.out.printf("Splitting '%s' with pattern '%s'%n", s, pattern);
List<String> tokens = split(s, pattern);
System.out.printf("Found %d matches%n", tokens.size());
int i = 0;
for (String token : tokens) {
System.out.printf(" %d/%d: '%s'%n", ++i, tokens.size(), token);
}
System.out.println();
}
public static void main(String args[]) {
testSplit("abcdefghij", "z"); // "abcdefghij"
testSplit("abcdefghij", "f"); // "abcde", "f", "ghi"
testSplit("abcdefghij", "j"); // "abcdefghi", "j", ""
testSplit("abcdefghij", "a"); // "", "a", "bcdefghij"
testSplit("abcdefghij", "[bdfh]"); // "a", "b", "c", "d", "e", "f", "g", "h", "ij"

All of these methods are great. I have found another simple resource that is a great example of creating a dynamic form using "onchange" with AJAX.
http://www.w3schools.com/php/php_ajax_database.asp
I simply modified the text table output to anther select dropdown populated based on the selection of the first drop down. For my application a user will select a state then the second dropdown will be populated with the cities for the selected state. Much like the JSON example above but with php and mysql.
you can use like this situation:
for example, you have a page: http://www.example.com/page.php
then in that page.php, insert this code:
if (!empty($_GET['doaction']) && $_GET['doaction'] == blabla ){
echo '<script>alert("hello");</script>';
}
then, whenever you visit this url: http://www.example.com/page.php?doaction=blabla
then the alert will be automatically called.
You can have as many different jQuery versions on your page as you want.
jQuery.noConflict()
:<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
<script>
var $i = jQuery.noConflict();
alert($i.fn.jquery);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
var $j = jQuery.noConflict();
alert($j.fn.jquery);
</script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script>
var $k = jQuery.noConflict();
alert($k.fn.jquery);

Apart from what is being mentioned above, .uniform()
can also be used for generating multiple random numbers that too with the desired shape which is not possible with .random()
np.random.seed(99)
np.random.random()
#generates 0.6722785586307918
while the following code
np.random.seed(99)
np.random.uniform(0.0, 1.0, size = (5,2))
#generates this
array([[0.67227856, 0.4880784 ],
[0.82549517, 0.03144639],
[0.80804996, 0.56561742],
[0.2976225 , 0.04669572],
[0.9906274 , 0.00682573]])
This can't be done with random(...), and if you're generating the random(...) numbers for ML related things, most of the time, you'll end up using .uniform(...)
So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.
protected void onCreate(Bundle savedInstanceState) { setContentView(R.layout.my_layout); Bitmap bitmap = getIntent().getParcelableExtra("image"); ImageView imageView = (ImageView) findViewById(R.id.imageview); imageView.setImageBitmap(bitmap); }
Suppose you have this file:
$ cat /tmp/test.txt
Line 1
Line 2 has leading space
Line 3 followed by blank line
Line 5 (follows a blank line) and has trailing space
Line 6 has no ending CR
There are four elements that will alter the meaning of the file output read by many Bash solutions:
If you want the text file line by line including blank lines and terminating lines without CR, you must use a while loop and you must have an alternate test for the final line.
Here are the methods that may change the file (in comparison to what cat
returns):
1) Lose the last line and leading and trailing spaces:
$ while read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'
(If you do while IFS= read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt
instead, you preserve the leading and trailing spaces but still lose the last line if it is not terminated with CR)
2) Using process substitution with cat
will reads the entire file in one gulp and loses the meaning of individual lines:
$ for p in "$(cat /tmp/test.txt)"; do printf "%s\n" "'$p'"; done
'Line 1
Line 2 has leading space
Line 3 followed by blank line
Line 5 (follows a blank line) and has trailing space
Line 6 has no ending CR'
(If you remove the "
from $(cat /tmp/test.txt)
you read the file word by word rather than one gulp. Also probably not what is intended...)
The most robust and simplest way to read a file line-by-line and preserve all spacing is:
$ while IFS= read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
' Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space '
'Line 6 has no ending CR'
If you want to strip leading and trading spaces, remove the IFS=
part:
$ while read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'
'Line 6 has no ending CR'
(A text file without a terminating \n
, while fairly common, is considered broken under POSIX. If you can count on the trailing \n
you do not need || [[ -n $line ]]
in the while
loop.)

It's easy to make a message, here's how:
First open notpad and type:
msg "Message",0,"Title"
and save it as Message.vbs.
Now in your batch file type:
Message.vbs %*
If your array of numbers always is starting with 1 and ending with X then you could use the following formula: sum = x * (x+1) / 2
from 1 till 100 the sum would be 100 * 101 / 2 = 5050
Here's what I do:

Considering the String
class' length
method returns an int
, the maximum length that would be returned by the method would be Integer.MAX_VALUE
, which is 2^31 - 1
(or approximately 2 billion.)
In terms of lengths and indexing of arrays, (such as char[]
, which is probably the way the internal data representation is implemented for String
s), Chapter 10: Arrays of The Java Language Specification, Java SE 7 Edition says the following:
The variables contained in an array have no names; instead they are referenced by array access expressions that use nonnegative integer index values. These variables are called the components of the array. If an array has
n
components, we sayn
is the length of the array; the components of the array are referenced using integer indices from0
ton - 1
, inclusive.
Furthermore, the indexing must be by int
values, as mentioned in Section 10.4:
Arrays must be indexed by
int
values;
Therefore, it appears that the limit is indeed 2^31 - 1
, as that is the maximum value for a nonnegative int
value.
However, there probably are going to be other limitations, such as the maximum allocatable size for an array.
You may try like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
g.drawRect (x, y, width, height); //can use either of the two//
g.fillRect (x, y, width, height);
g.setColor(color);
}
}
where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue
if you want to use rectangle object you could do it like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
g.setColor(color);
}
}
As has been pointed out many times, the suggestion to write code like this is problematic:
Public Function GetRandom(ByVal Min As Integer, ByVal Max As Integer) As Integer
Dim Generator As System.Random = New System.Random()
Return Generator.Next(Min, Max)
End Function
The reason is that the constructor for the Random
class provides a default seed based on the system's clock. On most systems, this has limited granularity -- somewhere in the vicinity of 20 ms. So if you write the following code, you're going to get the same number a bunch of times in a row:
Dim randoms(1000) As Integer
For i As Integer = 0 to randoms.Length - 1
randoms(i) = GetRandom(1, 100)
Next
The following code addresses this issue:
Public Function GetRandom(ByVal Min As Integer, ByVal Max As Integer) As Integer
' by making Generator static, we preserve the same instance '
' (i.e., do not create new instances with the same seed over and over) '
' between calls '
Static Generator As System.Random = New System.Random()
Return Generator.Next(Min, Max)
End Function
I threw together a simple program using both methods to generate 25 random integers between 1 and 100. Here's the output:

You want to use DateTimeOffset class.
var date = new DateTimeOffset(2009, 9, 1, 0, 0, 0, 0, new TimeSpan(0L));
var stringDate = date.ToString("u");
sorry I missed your original formatting with the miliseconds
var stringDate = date.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fff'Z'");
If you are willing to change your uri, you could also use PathVariable
.
@RequestMapping(value="/mapping/foo/{foo}/{bar}", method=RequestMethod.GET)
public String process(@PathVariable String foo,@PathVariable String bar) {
//Perform logic with foo and bar

I know this is a very old post, so some methods were not available back then. But here is my very simple take on it (based on Lolo's answer).
It relies on the HTML5 data-* attributes and therefore is very generic in that is uses jQuery's for-each function to get every .class matching "load-html" and uses its respective 'data-source' attribute to load the content:
<div class="container-fluid">
<div class="load-html" id="NavigationMenu" data-source="header.html"></div>
<div class="load-html" id="MainBody" data-source="body.html"></div>
<div class="load-html" id="Footer" data-source="footer.html"></div>
</div>
<script src="js/jquery.min.js"></script>
<script>
$(function () {
$(".load-html").each(function () {
$(this).load(this.dataset.source);
});
});
</script>
I found the solution. I misplaced the path to the keystore.jks
file.
Searched for the file on my computer used that path and everything worked great.
The Android Development Tools (ADT) plugin for Eclipse includes a visual editor for android application layout files:
I just got that problem when converting from %
formatting to .format()
.
Previous code:
"SET !TIMEOUT_STEP %{USER_TIMEOUT_STEP}d" % {'USER_TIMEOUT_STEP' = 3}
Problematic syntax:
"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format('USER_TIMEOUT_STEP' = 3)
The problem is that format
is a function that needs parameters. They cannot be strings.
That is one of worst python error messages I've ever seen.
Corrected code:
"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format(USER_TIMEOUT_STEP = 3)
I don't think that replacing "Require all denied" with "Require all granted" in this directive:
<Directory>
Options FollowSymLinks
AllowOverride None
#Require all denied
Require all granted
</Directory>
as suggested by Jan Czarny and seonded by user3801675 is the most secure way of solving this problem.
According to the Apache configuration files, that line denies access to the entirety of your server's filesystem. Replacing it might indeed allow access to your virtual host folders but at the price of allowing access to your entire computer as well!
Gev Balyan's approach seems to be the most secure approach here. It was the answer to the "access denied problems" plaguing me after setting up my new Apache server this morning.
Not to pile-on, but another pure-Bash approach takes advantage of ${//}
substitution of arrays:
$ arr=({1..100})
$ printf '%s' "${arr[@]/*/=}"

An alternative way would be to create a new temporary table with same structure.
CREATE TABLE temp_table AS SELECT * FROM original_table LIMIT 0
Then create the primary key in the table.
ALTER TABLE temp_table ADD PRIMARY KEY (primary-key-field)
Finally copy all records from the original table while ignoring the duplicate records.
INSERT IGNORE INTO temp_table AS SELECT * FROM original_table
Now you can delete the original table and rename the new table.
DROP TABLE original_table
RENAME TABLE temp_table TO original_table
It is also possible to use enumeration.
typedef enum {
typeNo1 = 1,
typeNo2,
typeNo3,
typeNo4,
NumOfTypes = typeNo4
} TypeOfSomething;
Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.
This will be a JRE and JDK package.
There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.
I have following solution and it worked for me.
Whenever login page is requested, write the referer value to the session:
@RequestMapping(value="/login", method = RequestMethod.GET)
public String login(ModelMap model,HttpServletRequest request) {
String referrer = request.getHeader("Referer");
if(referrer!=null){
request.getSession().setAttribute("url_prior_login", referrer);
}
return "user/login";
}
Then, after successful login custom implementation of SavedRequestAwareAuthenticationSuccessHandler
will redirect user to the previous page:
HttpSession session = request.getSession(false);
if (session != null) {
url = (String) request.getSession().getAttribute("url_prior_login");
}
Redirect the user:
if (url != null) {
response.sendRedirect(url);
}
Use ConfigParser.
Your config:
[myvars]
var_a: 'home'
var_b: 'car'
var_c: 15.5
Your python code:
import ConfigParser
config = ConfigParser.ConfigParser()
config.read("config.ini")
var_a = config.get("myvars", "var_a")
var_b = config.get("myvars", "var_b")
var_c = config.get("myvars", "var_c")
If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".
Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

You might get Component unavailable
if you import the jQuery script directly.
Maybe it's what @Conley was talking about...
You can use
@require http://userscripts.org/scripts/source/85365.user.js
which is an modified version to work on Greasemonkey, and then get the jQuery object
var $ = unsafeWindow.jQuery;
$("div").css("display", "none");
This answer is more explicit
a = [1,1,1,1,2,2,2,2,3,3,3,4,4]
d = {}
for item in a:
if item in d:
d[item] = d.get(item)+1
else:
d[item] = 1
for k,v in d.items():
print(str(k)+':'+str(v))
# output
#1:4
#2:4
#3:3
#4:2
#remove dups
d = set(a)
print(d)
#{1, 2, 3, 4}
This started happening to me when my database size grew and I was doing a lot of transactions on it.
Truth is there is probably some way to optimize either your queries or your DB but try these 2 queries for a work around fix.
Run this:
SET GLOBAL innodb_lock_wait_timeout = 5000;
And then this:
SET innodb_lock_wait_timeout = 5000;
This is my answer
#include<stdio.h>
int main()
{int mat[100][100];
int row,column,i,j;
printf("enter how many row and colmn you want:\n \n");
scanf("%d",&row);
scanf("%d",&column);
printf("enter the matrix:");
for(i=0;i<row;i++){
for(j=0;j<column;j++){
scanf("%d",&mat[i][j]);
}
printf("\n");
}
for(i=0;i<row;i++){
for(j=0;j<column;j++){
printf("%d \t",mat[i][j]);}
printf("\n");}
}
I just choose an approximate value for the row and column. My selected row or column will not cross the value.and then I scan the matrix element then make it in matrix size.

Parse the string into date, then compare using compareTo
, before
or after
Date d = new Date();
d.compareTo(anotherDate)
i.e
Date date1 = new SimpleDateFormat("MM/dd/yyyy").parse(date1string)
Date date2 = new SimpleDateFormat("MM/dd/yyyy").parse(date2string)
date1.compareTo(date2);
Copying the comment provided below by @MuhammadSaqib to complete this answer.
Returns the value 0 if the argument Date is equal to this Date; a value less than 0 if this Date is before the Date argument, and a value greater than 0 if this Date is after the Date argument. and NullPointerException - if anotherDate is null.

Just call mkdir C:\VTS
no matter what. It will simply report that the subdirectory already exists.
Edit: As others have noted, this does set the %ERRORLEVEL% if the folder already exists. If your batch (or any processes calling it) doesn't care about the error level, this method works nicely. Since the question made no mention of avoiding the error level, this answer is perfectly valid. It fulfills the needs of creating the folder if it doesn't exist, and it doesn't overwrite the contents of an existing folder. Otherwise follow Martin Schapendonk's answer.
prop.table is a nice friendly way of obtaining proportions of tables.
m <- matrix(1:4,2)
m
[,1] [,2]
[1,] 1 3
[2,] 2 4
Leaving margin blank gives you proportions of the whole table
prop.table(m, margin=NULL)
[,1] [,2]
[1,] 0.1 0.3
[2,] 0.2 0.4
Giving it 1 gives you row proportions
prop.table(m, 1)
[,1] [,2]
[1,] 0.2500000 0.7500000
[2,] 0.3333333 0.6666667
And 2 is column proportions
prop.table(m, 2)
[,1] [,2]
[1,] 0.3333333 0.4285714
[2,] 0.6666667 0.5714286
I have changed my connection string from
var myConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Persist Security Info=True;Jet OLEDB:Database Password=;",gisdbPath);
to this:
var myConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Mode=Share Deny None;Data Source={0};user id=Admin;password=;", gisdbPath);
It works fro me never asked for Microsoft.Jet.OLEDB.4.0'registered.
Assuming that yourObject.toString() returns "true" or "false", you can try
boolean b = Boolean.valueOf(yourObject.toString())
There are two ways to access properties of objects:
var obj = {a: 'foo', b: 'bar'};
obj.a //foo
obj['b'] //bar
Or, if you need to dynamically do it:
var key = 'b';
obj[key] //bar
If you don't already have it as an object, you'll need to convert it.
For a more complex example, let's assume you have an array of objects that represent users:
var users = [{name: 'Corbin', age: 20, favoriteFoods: ['ice cream', 'pizza']},
{name: 'John', age: 25, favoriteFoods: ['ice cream', 'skittle']}];
To access the age property of the second user, you would use users[1].age
. To access the second "favoriteFood" of the first user, you'd use users[0].favoriteFoods[2]
.
Another example: obj[2].key[3]["some key"]
That would access the 3rd element of an array named 2. Then, it would access 'key' in that array, go to the third element of that, and then access the property name some key
.
As Amadan noted, it might be worth also discussing how to loop over different structures.
To loop over an array, you can use a simple for loop:
var arr = ['a', 'b', 'c'],
i;
for (i = 0; i < arr.length; ++i) {
console.log(arr[i]);
}
To loop over an object is a bit more complicated. In the case that you're absolutely positive that the object is a plain object, you can use a plain for (x in obj) { }
loop, but it's a lot safer to add in a hasOwnProperty check. This is necessary in situations where you cannot verify that the object does not have inherited properties. (It also future proofs the code a bit.)
var user = {name: 'Corbin', age: 20, location: 'USA'},
key;
for (key in user) {
if (user.hasOwnProperty(key)) {
console.log(key + " = " + user[key]);
}
}
(Note that I've assumed whatever JS implementation you're using has console.log
. If not, you could use alert
or some kind of DOM manipulation instead.)
The same as @neobot's answer but a little more modern and succinct.
>>> l = range(5)
>>> " & ".join(["{}"]*len(l)).format(*l)

I believe the problem is that codecs.BOM_UTF8
is a byte string, not a Unicode string. I suspect the file handler is trying to guess what you really mean based on "I'm meant to be writing Unicode as UTF-8-encoded text, but you've given me a byte string!"
Try writing the Unicode string for the byte order mark (i.e. Unicode U+FEFF) directly, so that the file just encodes that as UTF-8:
import codecs
file = codecs.open("lol", "w", "utf-8")
file.write(u'\ufeff')
file.close()
(That seems to give the right answer - a file with bytes EF BB BF.)
EDIT: S. Lott's suggestion of using "utf-8-sig" as the encoding is a better one than explicitly writing the BOM yourself, but I'll leave this answer here as it explains what was going wrong before.
I ran into this issue too. It confused me until I realized what was wrong:
You have this:
include /etc/nginx/mime.types;
default_type application/octet-stream;
You want this:
default_type application/octet-stream;
include /etc/nginx/mime.types;
there appears to either be a bug in nginx or a deficiency in the docs (this could be the intended behavior, but it is odd)

We can add objects to Array basically in Two ways
let stringOne = "One"
let strigTwo = "Two"
let stringThree = "Three"
var array:[String] = []//If your array is string type
Type 1)
//To append elements at the end
array.append(stringOne)
array.append(stringThree)
Type 2)
//To add elements at specific index
array.insert(strigTwo, at: 1)
If you want to add two arrays
var array1 = [1,2,3,4,5]
let array2 = [6,7,8,9]
let array3 = array1+array2
print(array3)
array1.append(contentsOf: array2)
print(array1)

The idea behind reporting progress with the background worker is through sending a 'percent completed' event. You are yourself responsible for determining somehow 'how much' work has been completed. Unfortunately this is often the most difficult part.
In your case, the bulk of the work is database-related. There is to my knowledge no way to get progress information from the DB directly. What you can try to do however, is split up the work dynamically. E.g., if you need to read a lot of data, a naive way to implement this could be.
Divide the actual reading in smaller chunks, reporting progress every time one chunk is completed:
for (int i = 0; i < count; i++)
{
bgWorker.ReportProgress((100 * i) / count);
// ... (read data for step i)
}
createTRIGGER [dbo].[Table] ON [dbo].[table]

I ran into a lot of issues when trying to figure this out. Here is my setup,
Dev Env : Windows 10, Java : 1.8.0_25, Spring Boot : 2.0.3.RELEASE, Spring : 5.0.7.RELEASE
What I found is spring is sticking with the concept "Sensible defaults for configuration". What this translates in to is, you have to have all your property files as part of your war file. Once in there, you can then override them using the "--spring.config.additional-location" command line property to point to external property files. But this will NOT WORK if the property files are not part of the original war file.
Demo code: https://github.com/gselvara/spring-boot-property-demo/tree/master
import java.util.Random;
public class Main {
public static void main(String[] args) {
int a[] = new int [100];
Random rnd = new Random ();
for (int i = 0; i< a.length; i++) {
a[i] = rnd.nextInt(99-0)+0;
System.out.println(a[i]);
}
int max = 0;
for (int i = 0; i < a.length; i++) {
a[i] = max;
for (int j = i+1; j<a.length; j++) {
if (a[j] > max) {
max = a[j];
}
}
}
System.out.println("Max element: " + max);
}
}
This example made everything clear for me:

For regular Windows users who are not skilled with computers, it is practically not possible to install and use extensions from outside the Chrome Web Store.
Users of other operating systems (Linux, Mac, Chrome OS) can easily install unpacked extensions (in developer mode).
Windows users can also load an unpacked extension, but they will always see an information bubble with "Disable developer mode extensions" when they start Chrome or open a new incognito window, which is really annoying. The only way for Windows users to use unpacked extensions without such dialogs is to switch to Chrome on the developer channel, by installing https://www.google.com/chrome/browser/index.html?extra=devchannel#eula.
Extensions can be loaded in unpacked mode by following the following steps:
chrome://extensions
(via omnibox or menu -> Tools -> Extensions).If you have a crx
file, then it needs to be extracted first. CRX files are zip files with a different header. Any capable zip program should be able to open it. If you don't have such a program, I recommend 7-zip.
These steps will work for almost every extension, except extensions that rely on their extension ID. If you use the previous method, you will get an extension with a random extension ID. If it is important to preserve the extension ID, then you need to know the public key of your CRX file and insert this in your manifest.json. I have previously given a detailed explanation on how to get and use this key at https://stackoverflow.com/a/21500707.
I have faced the same situation while designing custom notification. I have tried with the following attribute set with true.
android:layout_centerInParent.
In addition to the other answers, I'd like to improve the removal, to something more generic:
$(this).closest('tr').remove();
This would be much better than using $(this).parent().parent().remove();
, because it doesn't depend on the depth of the element. So, the structure of the row becomes much more flexible.
Don't reinvent the wheel...:
org.apache.commons.lang.StringUtils.substring(String s, int start, int len)
Javadoc says:
StringUtils.substring(null, *, *) = null StringUtils.substring("", * , *) = ""; StringUtils.substring("abc", 0, 2) = "ab" StringUtils.substring("abc", 2, 0) = "" StringUtils.substring("abc", 2, 4) = "c" StringUtils.substring("abc", 4, 6) = "" StringUtils.substring("abc", 2, 2) = "" StringUtils.substring("abc", -2, -1) = "b" StringUtils.substring("abc", -4, 2) = "ab"
Thus:
StringUtils.substring("abc", 0, 4) = "abc"
ArrayList<String>[][] list = new ArrayList[10][10];

In the context of Drupal, the difference will depend whether clean URLs are on or not.
With them off, $_SERVER['REQUEST_URI']
will have the full path of the page as called w/ /index.php
, while $_GET["q"]
will just have what is assigned to q
.
With them on, they will be nearly identical w/o other arguments, but $_GET["q"]
will be missing the leading /
. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.
Two ways
1)instantiate the first class
and getter for arrayList
or
2)Make arraylist as static

are now available in Hive 1.2.0 and higher, which makes the code a lot cleaner.

As mentioned in earlier responses, this error can occur when interacting with a SOAP service over an HTTPS connection, and an issue is identified with the connection. The issue may be on the remote end (invalid cert) or on the client (in case of missing CA or PEM files). See http://php.net/manual/en/context.ssl.php for all possible SSL context settings. In my case, setting the path to my local certificate resolved the issue:
$context = ['ssl' => [
'local_cert' => '/path/to/pem/file',
]];
$params = [
'soap_version' => SOAP_1_2,
'trace' => 1,
'exceptions' => 1,
'connection_timeout' => 180,
'stream_context' => stream_context_create($context),
'cache_wsdl' => WSDL_CACHE_NONE, // eliminate possible issue from cached wsdl
];
$client = new SoapClient('https://remoteservice/wsdl', $params);
char a[2]
defines an array of char
's. a
is a pointer to the memory at the beginning of the array and using ==
won't actually compare the contents of a
with 'ab'
because they aren't actually the same types, 'ab'
is integer type. Also 'ab'
should be "ab"
otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.
Something that might be illustrative is looking at the typeid
of 'ab'
:
#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
int some_int =5;
std::cout << typeid('ab').name() << std::endl;
std::cout << typeid(some_int).name() << std::endl;
return 0;
}
on my system this returns:
i
i
showing that 'ab'
is actually evaluated as an int.
If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator ==
overloaded and will do a comparison check when called this way.
If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:
#include <iostream>
#include <string>
using namespace std;
int main(){
string a;
cout<<"enter ab ";
cin>>a;
if(a=="ab"){
cout<<"correct";
}
return 0;
}
This one is due to:
if(a=='ab')
, here, a
is const char*
type (ie : array of char)
'ab'
is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.
Since char
is a primitive type inherited from C, no operator ==
is defined.
the good code should be:
if(strcmp(a,"ab")==0)
, then you'll compare a const char*
to another const char*
using strcmp
.
Better way is to autowire with a constructor:
private final HttpServletRequest httpServletRequest;
public ClassConstructor(HttpServletRequest httpServletRequest){
this.httpServletRequest = httpServletRequest;
}
Tried many different ways, but liked the simplicity of this: https://github.com/ufoscout/docker-compose-wait
The idea that you can use ENV vars in the docker compose file to submit a list of services hosts (with ports) which should be "awaited" like this: WAIT_HOSTS: postgres:5432, mysql:3306, mongo:27017
.
So let's say you have the following docker-compose.yml file (copy/past from repo README):
version: "3"
services:
mongo:
image: mongo:3.4
hostname: mongo
ports:
- "27017:27017"
postgres:
image: "postgres:9.4"
hostname: postgres
ports:
- "5432:5432"
mysql:
image: "mysql:5.7"
hostname: mysql
ports:
- "3306:3306"
mySuperApp:
image: "mySuperApp:latest"
hostname: mySuperApp
environment:
WAIT_HOSTS: postgres:5432, mysql:3306, mongo:27017
Next, in order for services to wait, you need to add the following two lines to your Dockerfiles (into Dockerfile of the services which should await other services to start):
ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.5.0/wait /wait
RUN chmod +x /wait
The complete example of such sample Dockerfile (again from the project repo README):
FROM alpine
## Add your application to the docker image
ADD MySuperApp.sh /MySuperApp.sh
## Add the wait script to the image
ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.5.0/wait /wait
RUN chmod +x /wait
## Launch the wait tool and then your application
CMD /wait && /MySuperApp.sh
For other details about possible usage see README
This is from : Script to change password on linux servers over ssh
The script below will need to be saved as a file (eg ./passwdWrapper
) and made executable (chmod u+x ./passwdWrapper)
#!/usr/bin/expect -f
#wrapper to make passwd(1) be non-interactive
#username is passed as 1st arg, passwd as 2nd
set username [lindex $argv 0]
set password [lindex $argv 1]
set serverid [lindex $argv 2]
set newpassword [lindex $argv 3]
spawn ssh $serverid passwd
expect "assword:"
send "$password\r"
expect "UNIX password:"
send "$password\r"
expect "password:"
send "$newpassword\r"
expect "password:"
send "$newpassword\r"
expect eof
Then you can run ./passwdWrapper $user $password $server $newpassword
which will actually change the password.
Note: This requires that you install expect
on the machine from which you will be running the command. (sudo apt-get install expect
) The script works on CentOS 5/6 and Ubuntu 14.04, but if the prompts in passwd
change, you may have to tweak the expect

I have really simple solution for this.
just create a new class
.noHover{
pointer-events: none;
}
and use this to disable any event on it. use it like:
<a href='' class='btn noHover'>You cant touch ME :P</a>
To get the value of the Value attribute you can do something like this:
$("input[type='checkbox']").val();
Or if you have set a class
or id
for it, you can:
$('#check_id').val();
$('.check_class').val();
However this will return the same value whether it is checked or not, this can be confusing as it is different to the submitted form behaviour.
To check whether it is checked or not, do:
if ($('#check_id').is(":checked"))
{
// it is checked
}
You can use as below and also can use various color just assign
myLabel.textColor = UIColor.yourChoiceOfColor
Ex:
Swift
myLabel.textColor = UIColor.red
Objective-C
[myLabel setTextColor:[UIColor redColor]];
or you can click here to Choose the color,

I came upon this post looking to do the same and came up with my own solution I wanted to offer for future visitors of this page (and to see if doing this way presents any problems I had not forseen).
If you want to get a simple true
or false
output and want to do this with one line of code without a function or a loop you could serialize the array and then use stripos
to search for the value:
stripos(serialize($my_array),$needle)
It seems to work for me.
It's really easy to specify your own decimal separator. Just took me about 2 hours to figure it out :D.
You see that you were using the current ou other culture that you specify right? Well, the only thing the parser needs is an IFormatProvider. If you give it the
CultureInfo.CurrentCulture.NumberFormat
as a formatter, it will format the double according to your current culture's NumberDecimalSeparator
. What I did was just to create a new instance of the NumberFormatInfo
class and set it's NumberDecimalSeparator
property to whichever separator string I wanted. Complete code below:
double value = 2.3d;
NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = "-";
string x = value.ToString(nfi);
The result? "2-3"
Depends on where the file you are trying to include from is located.
Example:
/rootdir/pages/file.php
/someotherDir/index.php
If you wrote the following in index.php:
include('/rootdir/pages/file.php');
it would error becuase it would try to get:
/someotherDir/rootdir/pages/file.php
Which of course doesn't exist...
So you would have to use include('../rootdir/pages/file.php');
You should NOT run adb
server as root as other answers are suggesting. Instead if you are using Arch Linux do the following:
android-udev
package with PacmanReload udev rules:
# udevadm control --reload-rules
Add yourself to adbusers
group and then logout and login:
# usermod -aG adbusers $LOGNAME
Source: https://wiki.archlinux.org/index.php/android#Configuring_adb
Try this!
this.selectedObjectList = [{id:1}, {id:2}, {id:3}]
this.allObjectList = [{id:1}, {id:2}, {id:3}, {id:4}, {id:5}]
let newList = this.allObjectList.filter(e => this.selectedObjectList.find(a => e.id == a.id))
this.selectedObjectList = newList
Yes that is valid syntax but it may well not do what you want.
Execution will continue after your RAISERROR
except if you add a RETURN
. So you will need to add a block with BEGIN ... END
to hold the two statements.
Also I'm not sure why you plumped for severity 15. That usually indicates a syntax error.
Finally I'd simplify the conditions using IN
CREATE PROCEDURE [dbo].[AddApplicationUser] (@TenantId BIGINT,
@UserType TINYINT,
@UserName NVARCHAR(100),
@Password NVARCHAR(100))
AS
BEGIN
IF ( @TenantId IS NULL
AND @UserType IN ( 0, 1 ) )
BEGIN
RAISERROR('The value for @TenantID should not be null',15,1);
RETURN;
END
END
You can also pad a string to the required length using Guava's Strings.padEnd(String input, int minLength, char padding)
for file in *.jpg ; do mv $file ${file//IMG/myVacation} ; done
Again assuming that all your image files have the string "IMG" and you want to replace "IMG" with "myVacation".
With bash you can directly convert the string with parameter expansion.
Example: if the file is IMG_327.jpg, the mv
command will be executed as if you do mv IMG_327.jpg myVacation_327.jpg
. And this will be done for each file found in the directory matching *.jpg
.
IMG_001.jpg -> myVacation_001.jpg
IMG_002.jpg -> myVacation_002.jpg
IMG_1023.jpg -> myVacation_1023.jpg
etcetera...
I previously had this problem with my EC2 instance (I was serving couchdb to serve resources -- am considering Amazon's S3 for the future).
One thing to check (assuming Ec2) is that the couchdb port is added to your open ports within your security policy.
I specifically encountered
"[Errno 111] Connection refused"
over EC2 when the instance was stopped and started. The problem seems to be a pidfile race. The solution for me was killing couchdb (entirely and properly) via:
pkill -f couchdb
and then restarting with:
/etc/init.d/couchdb restart
You can use this:
select
table_name,column_name,referenced_table_name,referenced_column_name
from
information_schema.key_column_usage
where
referenced_table_name is not null
and table_schema = 'my_database'
and table_name = 'my_table'
Or for better formatted output use this:
select
concat(table_name, '.', column_name) as 'foreign key',
concat(referenced_table_name, '.', referenced_column_name) as 'references'
from
information_schema.key_column_usage
where
referenced_table_name is not null
and table_schema = 'my_database'
and table_name = 'my_table'
Here is something you could try.
Add this to any config files you use to run your app.
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)
require 'bundler/setup' # Set up gems listed in the Gemfile.
Bundler.require(:default)
Rails and other Rack based apps use this scheme. It happens sometimes that you are trying to run things which are some directories deeper than your root where your Gemfile normally is located. Of course you solved this problem for now but occasionally we all get into trouble with this finding the Gemfile. I sometimes like when you can have all you gems in the .bundle directory also. It never hurts to keep this site address under your pillow. http://bundler.io/
If you want to set a default entity property value, then you can initialize the entity field using the default value.
For instance, you can set the default createdOn
entity attribute to the current time, like this:
@Column(
name = "created_on"
)
private LocalDateTime createdOn = LocalDateTime.now();
If you are generating the DDL schema with JPA and Hibernate, although this is not recommended, you can use the columnDefinition
attribute of the JPA @Column
annotation, like this:
@Column(
name = "created_on",
columnDefinition = "DATETIME(6) DEFAULT CURRENT_TIMESTAMP"
)
@Generated(GenerationTime.INSERT)
private LocalDateTime createdOn;
The @Generated
annotation is needed because we want to instruct Hibernate to reload the entity after the Persistence Context is flushed, otherwise, the database-generated value will not be synchronized with the in-memory entity state.
Instead of using the columnDefinition
, you are better off using a tool like Flyway and use DDL incremental migration scripts. That way, you will set the DEFAULT
SQL clause in a script, rather than in a JPA annotation.
If you are using JPA with Hibernate, then you can also use the @ColumnDefault
annotation, like this:
@Column(name = "created_on")
@ColumnDefault(value="CURRENT_TIMESTAMP")
@Generated(GenerationTime.INSERT)
private LocalDateTime createdOn;
If you are using JPA with Hibernate and want to set the creation timestamp, then you can use the @CreationTimestamp
annotation, like this:
@Column(name = "created_on")
@CreationTimestamp
private LocalDateTime createdOn;
Rules are used to add additional functionality which applies to all tests within a test class, but in a more generic way.
For instance, ExternalResource executes code before and after a test method, without having to use @Before
and @After
. Using an ExternalResource
rather than @Before
and @After
gives opportunities for better code reuse; the same rule can be used from two different test classes.
The design was based upon: Interceptors in JUnit
For more information see JUnit wiki : Rules.
select convert(varchar(8), getdate(), 3)
simply use this for dd/mm/yy and this
select convert(varchar(8), getdate(), 1)
for mm/dd/yy
The code below will check whether the stored procedure already exists or not.
If it exists it will alter, if it doesn't exist it will create a new stored procedure for you:
//syntax for Create and Alter Proc
DECLARE @Create NVARCHAR(200) = 'Create PROCEDURE sp_cp_test';
DECLARE @Alter NVARCHAR(200) ='Alter PROCEDURE sp_cp_test';
//Actual Procedure
DECLARE @Proc NVARCHAR(200)= ' AS BEGIN select ''sh'' END';
//Checking For Sp
IF EXISTS (SELECT *
FROM sysobjects
WHERE id = Object_id('[dbo].[sp_cp_test]')
AND Objectproperty(id, 'IsProcedure') = 1
AND xtype = 'p'
AND NAME = 'sp_cp_test')
BEGIN
SET @Proc=@Alter + @Proc
EXEC (@proc)
END
ELSE
BEGIN
SET @Proc=@Create + @Proc
EXEC (@proc)
END
go
Both commands are correct
php_value post_max_size 30M

For Compare two date like MM/DD/YYYY to MM/DD/YYYY . Remember First thing column type of Field must be dateTime. Example : columnName : payment_date dataType : DateTime .
after that you can easily compare it. Query is :
select * from demo_date where date >= '3/1/2015' and date <= '3/31/2015'.

You can find your solution from apple's DEMO in this page: WWDC 2013 , find out and download UIImageEffects sample code.
Then with @Jeremy Fox's code. I changed it to
- (UIImage*)getDarkBlurredImageWithTargetView:(UIView *)targetView
{
CGSize size = targetView.frame.size;
UIGraphicsBeginImageContext(size);
CGContextRef c = UIGraphicsGetCurrentContext();
CGContextTranslateCTM(c, 0, 0);
[targetView.layer renderInContext:c]; // view is the view you are grabbing the screen shot of. The view that is to be blurred.
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return [image applyDarkEffect];
}
Hope this will help you.

An <input>
's width is generated from its size
attribute. The default size
is what's driving the auto width.
You could try width:100%
as illustrated in my example below.
Doesn't fill width:
<form action='' method='post' style='width:200px;background:khaki'>
<input style='width:auto' />
</form>
Fills width:
<form action='' method='post' style='width:200px;background:khaki'>
<input style='width:100%' />
</form>
Smaller size, smaller width:
<form action='' method='post' style='width:200px;background:khaki'>
<input size='5' />
</form>
UPDATE
Here's the best I could do after a few minutes. It's 1px off in FF, Chrome, and Safari, and perfect in IE. (The problem is #^&* IE applies borders differently than everyone else so it's not consistent.)
<div style='padding:30px;width:200px;background:red'>
<form action='' method='post' style='width:200px;background:blue;padding:3px'>
<input size='' style='width:100%;margin:-3px;border:2px inset #eee' />
<br /><br />
<input size='' style='width:100%' />
</form>
</div>
I'm assuming this should work. This will actually put it in the column in your database
UPDATE yourTable yt SET yt.Total = (yt.Pieces * yt.Price)
If you want to retrieve the 2 values from the database and put your multiplication in the third column of the result only, then
SELECT yt.Pieces, yt.Price, (yt.Pieces * yt.Price) as 'Total' FROM yourTable yt
will be your friend
Here's a flowchart based on this answer. See also, using script
to emulate a terminal.
Try this
$client = new \GuzzleHttp\Client();
$client->post(
'http://www.example.com/user/create',
array(
'form_params' => array(
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword'
)
)
);
The problem with using public field access is the same problem as using new instead of a factory method - if you change your mind later, all existing callers are broken. So, from an API evolution point of view, it's usually a good idea to bite the bullet and use getters/setters.
One place where I go the other way is when you strongly control access to the class, for example in an inner static class used as an internal data structure. In this case, it might be much clearer to use field access.
By the way, on e-bartek's assertion, it is highly unlikely IMO that property support will be added in Java 7.
just use this attribute
[System.Web.Http.HttpGet]
not need this line of code:
[System.Web.Http.AcceptVerbs("GET", "POST")]
Instead of downloading separate java files as suggested by Veer, you could just add this JAR file to your package.
To add the jar file to your project in Eclipse, do the following:
I was having trouble with .
ERROR: ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value for 'mat-checkbox-checked': 'true'. Current value: 'false'.
The Problem here is that the updated value is not detected until the next change Detection Cycle runs.
The easiest solution is to add a Change Detection Strategy. Add these lines to your code:
import { ChangeDetectionStrategy } from "@angular/core"; // import
@Component({
changeDetection: ChangeDetectionStrategy.OnPush,
selector: "abc",
templateUrl: "./abc.html",
styleUrls: ["./abc.css"],
})
Not sure if there is universally accepted standard but my own preferences are;
toString
, equals
and hashcode
nextRemove this line from your code:
console.info(JSON.parse(scatterSeries));
I don't know if anyone is still reading this thread or not, but Jeff's solution will only get you halfway there (kinda literally). What his onMeasure will do is display half the image in half the parent. The problem is that calling super.onMeasure prior to the setMeasuredDimension
will measure all the children in the view based on the original size, then just cut the view in half when the setMeasuredDimension
resizes it.
Instead, you need to call setMeasuredDimension
(as required for an onMeasure override) and provide a new LayoutParams
for your view, then call super.onMeasure
. Remember, your LayoutParams
are derived from your view's parent type, not your view's type.
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
this.setMeasuredDimension(parentWidth/2, parentHeight);
this.setLayoutParams(new *ParentLayoutType*.LayoutParams(parentWidth/2,parentHeight));
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
I believe the only time you'll have problems with the parent LayoutParams
is if the parent is an AbsoluteLayout
(which is deprecated but still sometimes useful).
You could just use
DataGridView1.CurrentRow.Cells["ColumnName"].Value
In your page_load
, add this:
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1;
"abc"
is a literal String.
In Java, these literal strings are pooled internally and the same String instance of "abc"
is used where ever you have that string literal declared in your code. So "abc" == "abc"
will always be true as they are both the same String instance.
Using the String.intern()
method you can add any string you like to the internally pooled strings, these will be kept in memory until java exits.
On the other hand, using new String("abc")
will create a new string object in memory, which is logically the same as the "abc"
literal.
"abc" == new String("abc")
will always be false, as although they are logically equal they refer to different instances.
Wrapping a String constructor around a string literal is of no value, it just needlessly uses more memory than it needs to.
I think you are confused because of a typo.
Replace print(words)
with print(word)
inside your loop to have every word printed on a different line
This will give you a sorted version of the array.
sorted(timestamps, reverse=True)
If you want to sort in-place:
timestamps.sort(reverse=True)
You can do this:
git diff branch1:path/to/file branch2:path/to/file
If you have difftool configured, then you can also:
git difftool branch1:path/to/file branch2:path/to/file

For the first one remove the spaces. Whitespace matters for the set command.
set guifont=Monaco:h20
For the second one it should be (the h specifies the height)
set guifont=Monospace:h20
My recommendation for setting the font is to do (if your version supports it)
set guifont=*
This will pop up a menu that allows you to select the font. After selecting the font, type
set guifont?
To show what the current guifont is set to. After that copy that line into your vimrc or gvimrc. If there are spaces in the font add a \
to escape the space.
set guifont=Monospace\ 20
Here's an utility function that I wrote to wrap the retry until success into a neater package. It uses the same basic structure, but prevents repetition. It could be modified to catch and rethrow the exception on the final try relatively easily.
def try_until(func, max_tries, sleep_time):
for _ in range(0,max_tries):
try:
return func()
except:
sleep(sleep_time)
raise WellNamedException()
#could be 'return sensibleDefaultValue'
Can then be called like this
result = try_until(my_function, 100, 1000)
If you need to pass arguments to my_function
, you can either do this by having try_until
forward the arguments, or by wrapping it in a no argument lambda:
result = try_until(lambda : my_function(x,y,z), 100, 1000)
Either create a directory under /app/src/main or use studio File-> New -> Folder - > Assets Folder.
I have tried many solution but could not find solution... but this link helped me... I want to give detail about issue...
I was running Instrumented test cases so my app was not visible in launcher... but it was installed and thus using Same Content Provider. So, I should uninstall it somehow. So Settings -> Application Manager -> All Downloaded Apps -> uninstall all apps from your current development package
Now, try to run... This will work...
Only because no one else has mentioned it:
>>> 'bob'.title()
'Bob'
>>> 'sandy'.title()
'Sandy'
>>> '1bob'.title()
'1Bob'
>>> '1sandy'.title()
'1Sandy'
However, this would also give
>>> '1bob sandy'.title()
'1Bob Sandy'
>>> '1JoeBob'.title()
'1Joebob'
i.e. it doesn't just capitalize the first alphabetic character. But then .capitalize()
has the same issue, at least in that 'joe Bob'.capitalize() == 'Joe bob'
, so meh.
So far we have three competing alternatives for how to do this:
Console.Write("\r{0} ", value); // Option 1: carriage return
Console.Write("\b\b\b\b\b{0}", value); // Option 2: backspace
{ // Option 3 in two parts:
Console.SetCursorPosition(0, Console.CursorTop); // - Move cursor
Console.Write(value); // - Rewrite
}
I've always used Console.CursorLeft = 0
, a variation on the third option, so I decided to do some tests. Here's the code I used:
public static void CursorTest()
{
int testsize = 1000000;
Console.WriteLine("Testing cursor position");
Stopwatch sw = new Stopwatch();
sw.Start();
for (int i = 0; i < testsize; i++)
{
Console.Write("\rCounting: {0} ", i);
}
sw.Stop();
Console.WriteLine("\nTime using \\r: {0}", sw.ElapsedMilliseconds);
sw.Reset();
sw.Start();
int top = Console.CursorTop;
for (int i = 0; i < testsize; i++)
{
Console.SetCursorPosition(0, top);
Console.Write("Counting: {0} ", i);
}
sw.Stop();
Console.WriteLine("\nTime using CursorLeft: {0}", sw.ElapsedMilliseconds);
sw.Reset();
sw.Start();
Console.Write("Counting: ");
for (int i = 0; i < testsize; i++)
{
Console.Write("\b\b\b\b\b\b\b\b{0,8}", i);
}
sw.Stop();
Console.WriteLine("\nTime using \\b: {0}", sw.ElapsedMilliseconds);
}
On my machine, I get the following results:
Additionally, SetCursorPosition
caused noticeable flicker that I didn't observe with either of the alternatives. So, the moral is to use backspaces or carriage returns when possible, and thanks for teaching me a faster way to do this, SO!
Update: In the comments, Joel suggests that SetCursorPosition is constant with respect to the distance moved while the other methods are linear. Further testing confirms that this is the case, however constant time and slow is still slow. In my tests, writing a long string of backspaces to the console is faster than SetCursorPosition until somewhere around 60 characters. So backspace is faster for replacing portions of the line shorter than 60 characters (or so), and it doesn't flicker, so I'm going to stand by my initial endorsement of \b over \r and SetCursorPosition
.
This should do it:
HTML
<input name="Name" value="Enter Your Name" onClick="blankDefault('Enter Your Name', this)">
JavaScript
function blankDefault(_text, _this) {
if(_text == _this.value)
_this.value = '';
}
There are better/less obtrusive ways though, but this will get the job done.
PSR-5: PHPDoc proposes a form of Generics-style notation.
Type[]
Type<Type>
Type<Type[, Type]...>
Type<Type[|Type]...>
Values in a Collection MAY even be another array and even another Collection.
Type<Type<Type>>
Type<Type<Type[, Type]...>>
Type<Type<Type[|Type]...>>
<?php
$x = [new Name()];
/* @var $x Name[] */
$y = new Collection([new Name()]);
/* @var $y Collection<Name> */
$a = new Collection();
$a[] = new Model_User();
$a->resetChanges();
$a[0]->name = "George";
$a->echoChanges();
/* @var $a Collection<Model_User> */
Note: If you are expecting an IDE to do code assist then it's another question about if the IDE supports PHPDoc Generic-style collections notation.
From my answer to this question.
import operator
sortedlist = sorted(reader, key=operator.itemgetter(3), reverse=True)
or use lambda

You might look at how pygame handles this to steal some ideas.
Keras now supports the use_bias=False
option, so we can save some computation by writing like
model.add(Dense(64, use_bias=False))
model.add(BatchNormalization(axis=bn_axis))
model.add(Activation('tanh'))
or
model.add(Convolution2D(64, 3, 3, use_bias=False))
model.add(BatchNormalization(axis=bn_axis))
model.add(Activation('relu'))
Unusual filenames (such as a file containing the valid \n
character can wreak havoc with this kind of parsing. Here's a way to do it in Perl:
perl -le '@sorted = map {$_->[0]}
sort {$a->[1] <=> $b->[1]}
map {[$_, -M $_]}
@ARGV;
print $sorted[0]
' b2*
That's a Schwartzian transform used there.
To make the round trip "The WordPress Way" on the "front-end" (doesn't work in the context of wp-admin
), you need to use 3 WordPress functions:
wp-admin
- so this will also not be available in admin-ajax
)Note: there's no need to even touch the superglobals ($_GET
) if you do it this way.
On the page where you need to create the link / set the query variable:
if it's a link back to this page, just adding the query variable
<a href="<?php echo esc_url( add_query_arg( 'c', $my_value_for_c ) )?>">
if it's a link to some other page
<a href="<?php echo esc_url( add_query_arg( 'c', $my_value_for_c, site_url( '/some_other_page/' ) ) )?>">
In your functions.php, or some plugin file or custom class (front-end only):
function add_custom_query_var( $vars ){
$vars[] = "c";
return $vars;
}
add_filter( 'query_vars', 'add_custom_query_var' );
On the page / function where you wish to retrieve and work with the query var set in your URL:
$my_c = get_query_var( 'c' );
wp-admin
)On the back end we don't ever run wp()
, so the main WP Query does not get run. As a result, there are no query vars
and the query_vars
hook is not run.
In this case, you'll need to revert to the more standard approach of examining your $_GET
superglobal. The best way to do this is probably:
$my_c = filter_input( INPUT_GET, "c", FILTER_SANITIZE_STRING );
though in a pinch you could do the tried and true
$my_c = isset( $_GET['c'] ? $_GET['c'] : "";
or some variant thereof.
I found above answers still have some unclear things, which will mislead users. First, It's sure that git push new_origin --all
and git push new_origin --mirror
can't duplicate all branches of origin, it just duplicate your local existed branches to your new_origin.
Below is two useful methods I have tested:
1,duplicate by clone bare repo.git clone --bare origin_url
, then enter the folder, and git push new_origin_url --mirror
.By this way, you can also use git clone --mirror origin_url
, both --bare
and --mirror
will download a bare repo,not including workspace. please refer this
2,If you have a git repo by using git clone
, which means you have bare repo and git workspace, you can use git remote add new_origin new_origin_url
, and then git push new_origin +refs/remotes/origin/\*:refs/heads/\*
,and then git push new_origin --tags
By this way, you will get a extra head branch, which make no sense.
If you happen to be an iOS developer
:
Check how many simulators that you have downloaded as they take up a lot of space:
Go to: ~/Library/Developer/Xcode/iOS DeviceSupport
Also delete old archived apps:
Go to: ~/Library/Developer/Xcode/Archives
I cleared 100GB doing this.
if you need to change specific option from the select menu you can do it like this
option[value="Basic"] {
color:red;
}
or you can change them all
select {
color:red;
}
In case you are trying to normalize each row such that its magnitude is one (i.e. a row's unit length is one or the sum of the square of each element in a row is one):
import numpy as np
a = np.arange(0,27,3).reshape(3,3)
result = a / np.linalg.norm(a, axis=-1)[:, np.newaxis]
# array([[ 0. , 0.4472136 , 0.89442719],
# [ 0.42426407, 0.56568542, 0.70710678],
# [ 0.49153915, 0.57346234, 0.65538554]])
Verifying:
np.sum( result**2, axis=-1 )
# array([ 1., 1., 1.])
Your class shoud look something like this:
class Something { int[] array; //global array, replace type of course void function1() { array = new int[10]; //let say you declare it here that will be 10 integers in size } void function2() { array[0] = 12; //assing value at index 0 to 12. } }
That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.
Careful - append()
will append HTML, and you may run into cross-site-scripting problems if you use it all the time and a user makes you append('<script>alert("Hello")</script>')
.
Use text()
to replace element content with text, or append(document.createTextNode(x))
to append a text node.
Another info: If you want use a Route Constraint, imagine that you want force that parameter has int datatype, then you need use this syntax:
[Route("v1/location/**{deviceOrAppid:int?}**", Name = "AddNewLocation")]
The ? character is put always before the last } character
For more information see: Optional URI Parameters and Default Values
use this one
//for getting length of object
int length = jsonObject.length();
or
//for getting length of array
int length = jsonArray.length();
The as
keyword is useful when you genuinely don't know what type the variable might be. If you have a single function that will follow different code paths depending upon the actual type of the parameter, then you have two choices:
First, using a normal cast:
if(myObj is string)
{
string value = (string)myObj;
... do something
}
else if(myObj is MyClass)
{
MyClass = (MyClass)myObj;
}
This requires that you check the type of the object using is
so that you don't try to cast it to something that will fail. This is also slightly redundant, as the is
-type checking is done again in the cast (so that it can throw the exception if required).
The alternative is to use as
.
string myString = myObj as string;
MyClass myClass = myObj as MyClass;
if(myString != null)
{
}
else if(myClass != null)
{
}
This makes the code somewhat shorter and also eliminates the redundant type checking.
Yes with the help of Arrays you can initialize array list in one line,
List<String> strlist= Arrays.asList("aaa", "bbb", "ccc");
