With hours, 0-padding minutes and seconds:

var ms = 298999;
var d = new Date(1000*Math.round(ms/1000)); // round to nearest second
function pad(i) { return ('0'+i).slice(-2); }
var str = d.getUTCHours() + ':' + pad(d.getUTCMinutes()) + ':' + pad(d.getUTCSeconds());
console.log(str); // 0:04:59

Two native solutions

• performance.now --> Call to ... took 6.414999981643632 milliseconds.
• console.time --> Call to ... took 5.815 milliseconds

The difference between both is precision.

For usage and explanation read on.

Performance.now (For microsecond precision use)

    var t0 = performance.now();
    doSomething();
    var t1 = performance.now();

    console.log("Call to doSomething took " + (t1 - t0) + " milliseconds.");
            
    function doSomething(){    
       for(i=0;i<1000000;i++){var x = i*i;}
    }

performance.now

Unlike other timing data available to JavaScript (for example Date.now), the timestamps returned by Performance.now() are not limited to one-millisecond resolution. Instead, they represent times as floating-point numbers with up to microsecond precision.

Also unlike Date.now(), the values returned by Performance.now() always increase at a constant rate, independent of the system clock (which might be adjusted manually or skewed by software like NTP). Otherwise, performance.timing.navigationStart + performance.now() will be approximately equal to Date.now().

console.time

Example: (timeEnd wrapped in setTimeout for simulation)

console.time('Search page');
  doSomething();
console.timeEnd('Search page');
 

 function doSomething(){    
       for(i=0;i<1000000;i++){var x = i*i;}
 }

You can change the Timer-Name for different operations.

Xcode 10

1. drag-n-drop a project into another project - is called cross-project references^[About]
2. add the added project as a build dependency - is called Explicit dependency^[About]

//Xcode 10
Build Phases -> Target Dependencies -> + Add items 

//Xcode 11
Build Phases -> Dependencies -> + Add items 

In Choose items to add: dialog you will see only targets from your project and the sub-project

Because the URL isn't on the same domain as your website, you need to use JSONP.

For example: (In jQuery):

$.getJSON(
    'http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=?', 
    function(data) { ... }
);

This works by creating a <script> tag like this one:

<script src="http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=someFunction" type="text/javascript"></script>

Their server then emits Javascript that calls someFunction with the data to retrieve.
`someFunction is an internal callback generated by jQuery that then calls your callback.

There is support for just this in the support library revision 23.3.0 (in the v4 which means compability back to Android 1.6).

In your Launcher activity, first call:

AppLaunchChecker.onActivityCreate(activity);

Then call:

AppLaunchChecker.hasStartedFromLauncher(activity);

Which will return if this was the first time the app was launched.

In the specific case of sed, the -i option that others have already mentioned is far and away the simplest and sanest one.

In the more general case, sponge, from the moreutils collection, does exactly what you want: it lets you replace a file with the result of processing it, in a way specifically designed to keep the processing step from tripping over itself by overwriting the very file it's working on. To quote the sponge man page:

sponge reads standard input and writes it out to the specified file. Unlike a shell redirect, sponge soaks up all its input before writing the output file. This allows constructing pipelines that read from and write to the same file.

I had the same error. The solution for me was change the ANDROID_HOME path. First I took a look into tools->android->sdk manager from Android Studio. In that window, we can see the path where Android Studio looks for the SDK: image

Then I opened a Windows CMD shell, executed:

echo %ANDROID_HOME%

but the path was different to the one in ANDROID STUDIO CONFIGURATION of the first step.

The solution was to change in user environment, the ANDROID_HOME, to the one of the first step: image

I finally closed the cmd shell, and opened another cmd shell to execute:

echo %ANDROID_HOME%

the path was updated, and I could run my emulator perfectly.

To disable inputting password:

sudo visudo

Then add a new line like below and save then:

# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer

Then you run installer without password:

sudo installer -pkg ...

I resolve this (On Eclipse IDE) by delete my old server and create the same again. This error is because you don't proper terminate Tomcat server and close Eclipse.

try this:

select SUBSTRING(sys.fn_sqlvarbasetostr(HASHBYTES('MD5',  '[email protected]' )),3,32) 

Maven version 3.2.1 added this feature, you can use the -pl switch (shortcut for --projects list) with ! or - (source) to exclude certain submodules.

mvn -pl '!submodule-to-exclude' install
mvn -pl -submodule-to-exclude install

Be careful in bash the character ! is a special character, so you either have to single quote it (like I did) or escape it with the backslash character.

The syntax to exclude multiple module is the same as the inclusion

mvn -pl '!submodule1,!submodule2' install
mvn -pl -submodule1,-submodule2 install

EDIT Windows does not seem to like the single quotes, but it is necessary in bash ; in Windows, use double quotes (thanks @awilkinson)

mvn -pl "!submodule1,!submodule2" install

In case you can't upgrade to Ruby on Rails 2.3.11 (and to expand on douglasr's answer), thread must be required at the top of boot.rb. For example:

require 'thread'

# Don't change this file!
# Configure your app in config/environment.rb and config/environments/*.rb
...

barcode often consist of large number so i think your app crashes because of the size of the string that you are trying to convert to int. you can use BigInteger

BigInteger reallyBig = new BigInteger(myString);

You can use the following:

$regex = '#<\s*?code\b[^>]*>(.*?)</code\b[^>]*>#s';

• \b ensures that a typo (like <codeS>) is not captured.
• The first pattern [^>]* captures the content of a tag with attributes (eg a class).
• Finally, the flag s capture content with newlines.

See the result here : http://lumadis.be/regex/test_regex.php?id=1081

It works for me. Please check if you are using the right imports?

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;

If you are accessing the live database by using localhost URL then it will not work. Please deploy your service or website on IIS and create URL and then access the database by using new URL, It will work.

For me only this one worked

git checkout -p filename

Not a direct answer to this question but rather to the "issue" of $event.currentTarget apparently be set to null.

This is due to the fact that console.log shows deep mutable objects at the last state of execution, not at the state when console.log was called.

You can check this for more information: Consecutive calls to console.log produce inconsistent results

you can use 'rpad' in your select query and specify the size ...

select rpad(a , 20) , rpad(b, 20) from x ;

where first parameter is your column name and second parameter is the size which you want to pad with .

There's no need to add space before closing quote if path doesn't contain trailing backslash, so following command should work:

robocopy "C:\Source Path" "C:\Destination Path" /option1 /option2...

But, following will not work:

robocopy "C:\Source Path\" "C:\Destination Path\" /option1 /option2...

This is due to the escaping issue that is described here:

The \ escape can cause problems with quoted directory paths that contain a trailing backslash because the closing quote " at the end of the line will be escaped \".

Using TimeUnit.SECONDS.sleep(1); or Thread.sleep(1000); Is acceptable way to do it. In both cases you have to catch InterruptedExceptionwhich makes your code Bulky.There is an Open Source java library called MgntUtils (written by me) that provides utility that already deals with InterruptedException inside. So your code would just include one line:

TimeUtils.sleepFor(1, TimeUnit.SECONDS);

See the javadoc here. You can access library from Maven Central or from Github. The article explaining about the library could be found here

The code I use for all browser gradients:

background: #0A284B;
background: -webkit-gradient(linear, left top, left bottom, from(#0A284B), to(#135887));
background: -webkit-linear-gradient(#0A284B, #135887);
background: -moz-linear-gradient(top, #0A284B, #135887);
background: -ms-linear-gradient(#0A284B, #135887);
background: -o-linear-gradient(#0A284B, #135887);
background: linear-gradient(#0A284B, #135887);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#0A284B', endColorstr='#135887');
zoom: 1;

You will need to specify a height or zoom: 1 to apply hasLayout to the element for this to work in IE.

Update:

Here is a LESS Mixin (CSS) version for all you LESS users out there:

.gradient(@start, @end) {
    background: mix(@start, @end, 50%);
    filter: ~"progid:DXImageTransform.Microsoft.gradient(startColorStr="@start~", EndColorStr="@end~")";
    background: -webkit-gradient(linear, left top, left bottom, from(@start), to(@end));
    background: -webkit-linear-gradient(@start, @end);
    background: -moz-linear-gradient(top, @start, @end);
    background: -ms-linear-gradient(@start, @end);
    background: -o-linear-gradient(@start, @end);
    background: linear-gradient(@start, @end);
    zoom: 1;
}

Run nohup python bgservice.py & to get the script to ignore the hangup signal and keep running. Output will be put in nohup.out.

Ideally, you'd run your script with something like supervise so that it can be restarted if (when) it dies.

You can use 'onclick' attribute like this :

<a ... href="javascript: onclick();" ...>...</a>

C++17 inline variables

This awesome C++17 feature allow us to:

• conveniently use just a single memory address for each constant
• store it as a constexpr: How to declare constexpr extern?
• do it in a single line from one header

main.cpp

#include <cassert>

#include "notmain.hpp"

int main() {
    // Both files see the same memory address.
    assert(&notmain_i == notmain_func());
    assert(notmain_i == 42);
}

notmain.hpp

#ifndef NOTMAIN_HPP
#define NOTMAIN_HPP

inline constexpr int notmain_i = 42;

const int* notmain_func();

#endif

notmain.cpp

#include "notmain.hpp"

const int* notmain_func() {
    return &notmain_i;
}

Compile and run:

g++ -c -o notmain.o -std=c++17 -Wall -Wextra -pedantic notmain.cpp
g++ -c -o main.o -std=c++17 -Wall -Wextra -pedantic main.cpp
g++ -o main -std=c++17 -Wall -Wextra -pedantic main.o notmain.o
./main

C++ standard on inline variables

The C++ standard guarantees that the addresses will be the same. C++17 N4659 standard draft 10.1.6 "The inline specifier":

6 An inline function or variable with external linkage shall have the same address in all translation units.

cppreference https://en.cppreference.com/w/cpp/language/inline explains that if static is not given, then it has external linkage.

Inline variable implementation

We can observe how it is implemented with:

nm main.o notmain.o

which contains:

main.o:
                 U _GLOBAL_OFFSET_TABLE_
                 U _Z12notmain_funcv
0000000000000028 r _ZZ4mainE19__PRETTY_FUNCTION__
                 U __assert_fail
0000000000000000 T main
0000000000000000 u notmain_i

notmain.o:
0000000000000000 T _Z12notmain_funcv
0000000000000000 u notmain_i

and man nm says about u:

"u" The symbol is a unique global symbol. This is a GNU extension to the standard set of ELF symbol bindings. For such a symbol the dynamic linker will make sure that in the entire process there is just one symbol with this name and type in use.

so we see that there is a dedicated ELF extension for this.

C++17 standard draft on "global" const implies static

This is the quote for what was mentioned at: https://stackoverflow.com/a/12043198/895245

C++17 n4659 standard draft 6.5 "Program and linkage":

3 A name having namespace scope (6.3.6) has internal linkage if it is the name of

• (3.1) — a variable, function or function template that is explicitly declared static; or,
• (3.2) — a non-inline variable of non-volatile const-qualified type that is neither explicitly declared extern nor previously declared to have external linkage; or
• (3.3) — a data member of an anonymous union.

"namespace" scope is what we colloquially often refer to as "global".

Annex C (informative) Compatibility, C.1.2 Clause 6: "basic concepts" gives the rationale why this was changed from C:

6.5 [also 10.1.7]

Change: A name of file scope that is explicitly declared const, and not explicitly declared extern, has internal linkage, while in C it would have external linkage.

Rationale: Because const objects may be used as values during translation in C++, this feature urges programmers to provide an explicit initializer for each const object. This feature allows the user to put const objects in source files that are included in more than one translation unit.

Effect on original feature: Change to semantics of well-defined feature.

Difficulty of converting: Semantic transformation.

How widely used: Seldom.

See also: Why does const imply internal linkage in C++, when it doesn't in C?

Tested in GCC 7.4.0, Ubuntu 18.04.

Stupid as it may sound but all "Provisioning Profiles" re-appear under "Organizer - Devices" once you connect a real device.

You can use TextView.setLineSpacing(n,m) function.

You can use http_build_query to generate a URL-encoded querystring from an array in PHP. Whilst the resulting querystring will be expanded, you can decide on a unique separator you want as a parameter to the http_build_query method, so when it comes to decoding, you can check what separator was used. If it was the unique one you chose, then that would be the array querystring otherwise it would be the normal querystrings.

Another possibility to circumvent the problem is to use a proxy script. That method is described for example here

You can use the instanceof operator for this. From MDN:

The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototype chain of an object.

If you don't know what prototypes and prototype chains are I highly recommend looking it up. Also here is a JS (TS works similar in this respect) example which might clarify the concept:

    class Animal {_x000D_
        name;_x000D_
    _x000D_
        constructor(name) {_x000D_
            this.name = name;_x000D_
        }_x000D_
    }_x000D_
    _x000D_
    const animal = new Animal('fluffy');_x000D_
    _x000D_
    // true because Animal in on the prototype chain of animal_x000D_
    console.log(animal instanceof Animal); // true_x000D_
    // Proof that Animal is on the prototype chain_x000D_
    console.log(Object.getPrototypeOf(animal) === Animal.prototype); // true_x000D_
    _x000D_
    // true because Object in on the prototype chain of animal_x000D_
    console.log(animal instanceof Object); _x000D_
    // Proof that Object is on the prototype chain_x000D_
    console.log(Object.getPrototypeOf(Animal.prototype) === Object.prototype); // true_x000D_
    _x000D_
    console.log(animal instanceof Function); // false, Function not on prototype chain_x000D_
    _x000D_
    

The prototype chain in this example is:

animal > Animal.prototype > Object.prototype

Maybe the anwswers here are obsolete... in any case, for me running Symfony 4, it is easy Just type symfony -V from the command line.

Because you cannot have a general algorithm for every locale, no. You have to implement your own algorithm for every locale that you are supporting.

** EDIT **

Just for the heck of it, I played around until I got this class. It cannot display Long.MIN_VALUE because of bit restrictions... but I presume it could be modified and change long value types to double for decimal or even bigger numbers It can display any numbers up to 66 digits and 26 decimals using a string representation of the number. You may add more ScaleUnit for more decimals...

You can do it by simply aliasing the MAMP php on Apple terminal:

alias phpmamp='/Applications/MAMP/bin/php/php7.0.0/bin/php'

Example: > phpmamp - v

Now you can run something like: > phpmamp scriptname.php

Note: This will be applied only for the current terminal session.

Thowable catches really everything even ThreadDeath which gets thrown by default to stop a thread from the now deprecated Thread.stop() method. So by catching Throwable you can be sure that you'll never leave the try block without at least going through your catch block, but you should be prepared to also handle OutOfMemoryError and InternalError or StackOverflowError.

Catching Throwable is most useful for outer server loops that delegate all sorts of requests to outside code but may itself never terminate to keep the service alive.

Other way is with:

np.vectorize(lambda x: 6 <= x <= 10)(a)

which returns:

array([False, False, False,  True,  True,  True, False, False, False])

It is sometimes useful for masking time series, vectors, etc.

It looks like you are looking for SimpleDateFormat.

Format: yyyy-MM-dd kk:mm:ss

You can use % operator to check divisiblity of a given number

The code to check whether given no. is divisible by 3 or 5 when no. less than 1000 is given below:

n=0
while n<1000:
    if n%3==0 or n%5==0:
        print n,'is multiple of 3 or 5'
    n=n+1

A just in time compiler (JIT) is a piece of software which takes receives an non executable input and returns the appropriate machine code to be executed. For example:

Intermediate representation    JIT    Native machine code for the current CPU architecture

     Java bytecode            --->        machine code
     Javascript (run with V8) --->        machine code

The consequence of this is that for a certain CPU architecture the appropriate JIT compiler must be installed.

Difference compiler, interpreter, and JIT

Although there can be exceptions in general when we want to transform source code into machine code we can use:

1. Compiler: Takes source code and returns a executable
2. Interpreter: Executes the program instruction by instruction. It takes an executable segment of the source code and turns that segment into machine instructions. This process is repeated until all source code is transformed into machine instructions and executed.
3. JIT: Many different implementations of a JIT are possible, however a JIT is usually a combination of a compliler and an interpreter. The JIT first turn intermediary data (e.g. Java bytecode) which it receives into machine language via interpretation. A JIT can often sense when a certain part of the code is executed often and the will compile this part for faster execution.

If you have a project created in Swift 4 and then added Objective-C files, do it like this:

@objcMembers
public class MyModel: NSObject {
    var someFlag = false         
    func doSomething() {         
        print("doing something")
    }
}

To select every nth element from any starting position in the vector

nth_element <- function(vector, starting_position, n) { 
  vector[seq(starting_position, length(vector), n)] 
  }

# E.g.
vec <- 1:12

nth_element(vec, 1, 3)
# [1]  1  4  7 10

nth_element(vec, 2, 3)
# [1]  2  5  8 11

A good combination of String extensions:

public static byte[] GetBytes(this string str)
{
    byte[] bytes = new byte[str.Length * sizeof(char)];
    System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
    return bytes;
}

public static Stream ToStream(this string str)
{
    Stream StringStream = new MemoryStream();
    StringStream.Read(str.GetBytes(), 0, str.Length);
    return StringStream;
}

In iPython 3.0.0, the inline backend needs to be configured in ipython_kernel_config.py. You need to manually add the c.InlineBackend.rc... line (as mentioned in Greg's answer). This will affect both the inline backend in the Qt console and the notebook.

i also facing this same problem in django server.So i changed DEBUG = True in settings.py file its working

It's an old question. But for those who come across this question...

The white background behind the rounded corners is not actually the container. That is the canvas color of the app.

TO FIX: Change the canvas color of your app to Colors.transparent

Example:

return new MaterialApp(
  title: 'My App',
  theme: new ThemeData(
    primarySwatch: Colors.green,
    canvasColor: Colors.transparent, //----Change to this------------
    accentColor: Colors.blue,
  ),
  home: new HomeScreen(),
);

Android Support V7 GridLayout library makes excess space distribution easy by accommodating the principle of weight. To make a column stretch, make sure the components inside it define a weight or a gravity. To prevent a column from stretching, ensure that one of the components in the column does not define a weight or a gravity. Remember to add dependency for this library. Add com.android.support:gridlayout-v7:25.0.1 in build.gradle.

Here is my function to have a pretty var_dump. Combined with Xdebug, it helps a lot to have a better view of what we are dumping.

I improved a bit the display of Xdebug (give some space around, separator between values, wrap long variables, etc).

When you call the function, you can set a title, a background, a text color to distinguish all your var_dump in a page.

Or not ;)

This should work for you :) Yes var should be used

Can allso look at Array.Sort Method http://msdn.microsoft.com/en-us/library/aa311213(v=vs.71).aspx

e.g. Array.Sort(array, delegate(object[] x, object[] y){ return (x[ i ] as IComparable).CompareTo(y[ i ]);});

from http://channel9.msdn.com/forums/Coffeehouse/189171-Sorting-Two-Dimensional-Arrays-in-C/

You can certainly extract that part of a string and that's a great way to parse out data. Regular expression syntax varies a lot so you need to reference the help file for the regex you're using. You might try a regular expression like:

[0-9]+ *[a-zA-Z]+,([0-9]+) *[a-zA-Z]+,[0-9]+ *[a-zA-Z]+

If your regex program can do string replacement then replace the entire string with the result you want and you can easily use that result.

You didn't mention if you're using bash or some other shell. That would help get better answers when asking for help.

How about i-net Clear Reports (used to be i-net Crystal-Clear).

Though not free, you should also consider this low-cost, non-free, non-open-source reporting solution that can fully compete with Crystal Reports - and is Java-based.

I think it's even more cost efficient than "free ones". A small company may have to think closely about free things, but will then have to invest into manpower to find out how everything works and so on. Large companies will for sure subscribe to premium support services that cost a lot. See this article for reference

i-net Clear Reports has a very low price tag with great support for free and even better premium support via yearly subscriptions.

Disclosure: Yeah, I work for the company who built this, so I'm biased. But I honestly believe in what I just wrote.

Assigning Comparison to property value

JavaScript

You could assign the comparison of the property to "1"

obj["isChecked"] = (obj["isChecked"]==="1");

This only evaluates for a String value of "1" though. Other variables evaulate to false like an actual typeof number would be false. (i.e. obj["isChecked"]=1)

If you wanted to be indiscrimate about "1" or 1, you could use:

obj["isChecked"] = (obj["isChecked"]=="1");

Example Outputs

console.log(obj["isChecked"]==="1"); // true
console.log(obj["isChecked"]===1); // false
console.log(obj["isChecked"]==1); // true
console.log(obj["isChecked"]==="0"); // false
console.log(obj["isChecked"]==="Elephant"); // false

PHP

Same concept in PHP

$obj["isChecked"] = ($obj["isChecked"] == "1");

The same operator limitations as stated above for JavaScript apply.

Double Not

The 'double not' also works. It's confusing when people first read it but it works in both languages for integer/number type values. It however does not work in JavaScript for string type values as they always evaluate to true:

JavaScript

!!"1"; //true
!!"0"; //true
!!1; //true
!!0; //false
!!parseInt("0",10); // false

PHP

echo !!"1"; //true
echo !!"0"; //false
echo !!1; //true
echo !!0; //false

From the tutorial:

from sqlalchemy import or_
filter(or_(User.name == 'ed', User.name == 'wendy'))

React components expose all the standard Javascript mouse events in their top-level interface. Of course, you can still use :hover in your CSS, and that may be adequate for some of your needs, but for the more advanced behaviors triggered by a hover you'll need to use the Javascript. So to manage hover interactions, you'll want to use onMouseEnter and onMouseLeave. You then attach them to handlers in your component like so:

<ReactComponent
    onMouseEnter={() => this.someHandler}
    onMouseLeave={() => this.someOtherHandler}
/>

You'll then use some combination of state/props to pass changed state or properties down to your child React components.

If you want to add the elements with index, you could instead use an array.

    String [] test = new String[length];
    test[0] = "add";

If you want this in config, you can set npm config like so:

npm config set prefix "$(pwd)/vendor/node_modules"

or

npm config set prefix "$HOME/vendor/node_modules"

Check your config with

npm config ls -l

Or as @pje says and use the --prefix flag

It seems odd that this directory was not created at install - have you manually changed the path of the socket file in the my.cfg?

Have you tried simply creating this directory yourself, and restarting the service?

mkdir -p /var/run/mysqld
chown mysql:mysql /var/run/mysqld

textView.setGravity(Gravity.CENTER | Gravity.BOTTOM);

This will set gravity of your textview.

To pass XML content, you need to wrap the content in a Reader, and unmarshal that instead:

JAXBContext jaxbContext = JAXBContext.newInstance(Person.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

StringReader reader = new StringReader("xml string here");
Person person = (Person) unmarshaller.unmarshal(reader);

This is an html5 error like has been said, you can still have the button as a submit (if you want to cover both javascript and non javascript users) using it like:

     <button type="submit" onclick="return false"> Register </button>

This way you will cancel the submit but still do whatever you are doing in jquery or javascript function`s and do the submit for users who dont have javascript.

I would stick with normal approach to call the file directly, but if you really want to call a function, have a look at JSON-RPC (JSON Remote Procedure Call).

You basically send a JSON string in a specific format to the server, e.g.

{ "method": "echo", "params": ["Hello JSON-RPC"], "id": 1}

which includes the function to call and the parameters of that function.

Of course the server has to know how to handle such requests.
Here is jQuery plugin for JSON-RPC and e.g. the Zend JSON Server as server implementation in PHP.

This might be overkill for a small project or less functions. Easiest way would be karim's answer. On the other hand, JSON-RPC is a standard.

This is a linker issue. Try:

g++ -o test_1 test_1.cpp `pkg-config opencv --cflags --libs`

This should work to compile the source. However, if you recently compiled OpenCV from source, you will meet linking issue in run-time, the library will not be found. In most cases, after compiling libraries from source, you need to do finally:

sudo ldconfig

I think you may be after

select 
    jobID, JobName,
    sum(case when Priority = 1 then 1 else 0 end) as priority1,
    sum(case when Priority = 2 then 1 else 0 end) as priority2,
    sum(case when Priority = 3 then 1 else 0 end) as priority3,
    sum(case when Priority = 4 then 1 else 0 end) as priority4,
    sum(case when Priority = 5 then 1 else 0 end) as priority5
from
    Jobs
group by 
    jobID, JobName

However I am uncertain if you need to the jobID and JobName in your results if so remove them and remove the group by,

You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.

You will probably also need the .classpath file in the project directory that contains the test class.

Like the run configurations, they're XML files (even if they don't have an xml extension).

They don't get submitted, because that's what it says in the W3C specification.

17.13.2 Successful controls

A successful control is "valid" for submission. [snip]

• Controls that are disabled cannot be successful.

In other words, the specification says that controls that are disabled are considered invalid and should not be submitted.

If You want to have a reference to this variable across the whole project, create somewhere d.ts file, e.g. globals.d.ts. Fill it with your global variables declarations, e.g.:

declare const BootBox: 'boot' | 'box';

Now you can reference it anywhere across the project, just like that:

const bootbox = BootBox;

Here's an example.

I would suggest using System.Runtime.Serialization.Json that is part of .NET 4.5.

[DataContract]
public class Foo
{
   [DataMember(Name = "data")]
   public Dictionary<string,string> Data { get; set; }
}

Then use it like this:

var serializer = new DataContractJsonSerializer(typeof(List<Foo>));
var jsonParams = @"{""data"": [{""Key"":""foo"",""Value"":""bar""}] }";
var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonParams));

var obj = serializer.ReadObject(stream);
Console.WriteLine(obj);

Go to settings->Plugins->Browse repositories and search for Lombok it will display the Lombok plugin also you will see the install option on the right side panel. Please install it. Then restart your intelliJ IDE. This has solved my issue.

Implement Comparable interface to Fruit.

public class Fruit implements Comparable<Fruit> {

It implements the method

@Override
    public int compareTo(Fruit fruit) {
        //write code here for compare name
    }

Then do call sort method

Collections.sort(fruitList);

Right click on a file → Ignore → Ignore everything beneath.

If the Ignore option is grayed out then:

1. Stage a file first
2. Right click → Stop Tracking
3. That file will appear in the pane below with a question mark → Right click on it→ Ignore

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

To follow debobroto das's answer you can also put after

input.reset();
input.next(); 

I had the same problem and when I tried this. It completely fixed it.

I know I am late to answer this question but I would like to add something to answer of @Ethan, the highest voted and accepted answer.

We can use yargs to get the command line parameter and with that we can also add our own alias for some parameters like follow.

var args = require('yargs')
    .alias('r', 'release')
    .alias('d', 'develop')
    .default('release', false)
    .argv;

Kindly refer this link for more details. https://github.com/yargs/yargs/blob/HEAD/docs/api.md

Following is use of alias as per given in documentation of yargs. We can also find more yargs function there and can make the command line passing experience even better.

.alias(key, alias)

Set key names as equivalent such that updates to a key will propagate to aliases and vice-versa.

Optionally .alias() can take an object that maps keys to aliases. Each key of this object should be the canonical version of the option, and each value should be a string or an array of strings.

To check if a path is an existing file:

os.path.isfile(path)

Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

Why Not Use an Inner Class (Nesting)

class A extends B {
    private class C extends D {
        //Classes A , B , C , D accessible here 
    }
}

I was struggling from this for a while, tried almost all the solutions here but could not get rid of debugging info in TF 1.14, I have tried following multiple solutions:

import os
import logging
import sys

os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'  # FATAL
stderr = sys.stderr
sys.stderr = open(os.devnull, 'w')

import tensorflow as tf
tf.get_logger().setLevel(tf.compat.v1.logging.FATAL)
tf.compat.v1.logging.set_verbosity(tf.compat.v1.logging.ERROR)
logging.getLogger('tensorflow').setLevel(tf.compat.v1.logging.FATAL)

sys.stderr = stderr

import absl.logging
logging.root.removeHandler(absl.logging._absl_handler)
absl.logging._warn_preinit_stderr = False

The debugging info still showed up, what finally helped was restarting my pc (actually restarting the kernel should work). So if somebody has similar problem, try restart kernel after you set your environment vars, simple but might not come in mind.

An alternative solution is to commit the changes, and then get rid of those commits. This does not have an immediate benefit at first, but it opens up the possibility to commit in chunks, and to create a git tag for backup.

You can do it on the current branch, like this:

git add (-A) .
git commit -m"DISCARD: Temporary local changes"
git tag archive/local-changes-2015-08-01  # optional
git revert HEAD
git reset HEAD^^

Or you can do it on detached HEAD. (assuming you start on BRANCHNAME branch):

git checkout --detach HEAD
git add (-A) .
git commit -m"DISCARD: Temporary local changes"
git tag archive/local-changes-2015-08-01  # optional
git checkout BRANCHNAME

However, what I usually do is to commit in chunks, then name some or all commits as "DISCARD: ...". Then use interactive rebase to remove the bad commits and keep the good ones.

git add -p  # Add changes in chunks.
git commit -m"DISCARD: Some temporary changes for debugging"
git add -p  # Add more stuff.
git commit -m"Docblock improvements"
git tag archive/local-changes-2015-08-01
git rebase -i (commit id)  # rebase on the commit id before the changes.
  # Remove the commits that say "DISCARD".

This is more verbose, but it allows to review exactly which changes you want to discard.

The git lol and git lola shortcuts have been very helpful with this workflow.

weight values 0-1 share distribution of available space (after setting layout_width="0px") in proportion to the weight value. View elements with weight not specified (no weight entry) get weight 0 which means they get no expansion.

A simple alternative with no weight entries needed is to attach marquee to a view with text which tells it to expand from minimum needed for the text (wrap_content) to space available EditText: android:layout_width="wrap_content" android:ellipsize="marquee"

If you have Perl 5.14 or greater, you can use the /r option with the substitution operator to perform non-destructive substitution:

print "bla: ", $myvar =~ s/a/b/r, "\n";

In earlier versions you can achieve the same using a do() block with a temporary lexical variable, e.g.:

print "bla: ", do { (my $tmp = $myvar) =~ s/a/b/; $tmp }, "\n";

You need to add a break statement:

switch (searchType)
{
case "SearchBooks":
    Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
    Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
    break;
case "SearchAuthors":
    Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
    Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
    break;
}

This assumes that you want to either handle the SearchBooks case or the SearchAuthors - as you had written in, in a traditional C-style switch statement the control flow would have "fallen through" from one case statement to the next meaning that all 4 lines of code get executed in the case where searchType == "SearchBooks".

The compiler error you are seeing was introduced (at least in part) to warn the programmer of this potential error.

As an alternative you could have thrown an error or returned from a method.

Create with Resource Method

php artisan make:controller --resource ControllerName  --model=ModelName

Use It With a path

php artisan make:controller --resource path/ControllerName  --model=ModelName

I hit this challenge today and I found these answers useful but not quite explicit enough for me.

Edit: Just found the Apache Commons Email that wraps this up nicely, meaning you don't need to know below.

If your requirement is an email with:

1. text and html versions
2. html version has embedded (inline) images
3. attachments

The only structure I found that works with Gmail/Outlook/iPad is:

• mixed
  • alternative
    • text
    • related
      • html
      • inline image
      • inline image
  • attachment
  • attachment

A binary search tree uses the definition: that for every node,the node to the left of it has a less value(key) and the node to the right of it has a greater value(key).

Where as the heap,being an implementation of a binary tree uses the following definition:

If A and B are nodes, where B is the child node of A,then the value(key) of A must be larger than or equal to the value(key) of B.That is, key(A) = key(B).

I ran in the same question today for my exam and I got it right. smile ... :)

For angular 5+ version. Putting version helps as angular makes lot of changes.

ngOnInit() {

 this.myForm = formBuilder.group({
      firstName: 'Thomas',
      lastName: 'Mann'
    })
this.formControlValueChanged() // Note if you are doing an edit/fetching data from an observer this must be called only after your form is properly initialized otherwise you will get error.
}

formControlValueChanged(): void {       
        this.myForm.valueChanges.subscribe(value => {
            console.log('value changed', value)
        })
}

I tend to go for this pattern:

public class DogWithBreed
{
    public Dog Dog { get; set; }
    public string BreedName  { get; set; }
}

public IQueryable<DogWithBreed> GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    var result = from d in db.Dogs
                 join b in db.Breeds on d.BreedId equals b.BreedId
                 select new DogWithBreed()
                        {
                            Dog = d,
                            BreedName = b.BreedName
                        };
    return result;
}

It means you have an extra class, but it's quick and easy to code, easily extensible, reusable and type-safe.

If you look at the JarFile API you'll see that it's a subclass of the ZipFile class.

The jar-specific classes mostly just add jar-specific functionality, like direct support for manifest file attributes and so on.

It's OOP "in action"; since jar files are zip files, the jar classes can use zip functionality and provide additional utility.

Sybase has the same case syntax as SQL Server:

Description

Supports conditional SQL expressions; can be used anywhere a value expression can be used.

Syntax

case 
     when search_condition then expression 
    [when search_condition then expression]...
    [else expression]
end

Case and values syntax

case expression
     when expression then expression 
    [when expression then expression]...
    [else expression]
end

Parameters

case

begins the case expression.

when

precedes the search condition or the expression to be compared.

search_condition

is used to set conditions for the results that are selected. Search conditions for case expressions are similar to the search conditions in a where clause. Search conditions are detailed in the Transact-SQL User’s Guide.

then

precedes the expression that specifies a result value of case.

expression

is a column name, a constant, a function, a subquery, or any combination of column names, constants, and functions connected by arithmetic or bitwise operators. For more information about expressions, see “Expressions” in.

Example

select disaster, 
       case

If you're seeing this problem after you've made a modification to the Keycloak context path, you'll need to make an additional change to a redirect url setting:

1. Change <web-context>yourchange/auth</web-context> back to <web-context>auth</web-context> in standalone.xml
2. Restart Keycloak and navigate to the login page (/auth/admin)
3. Log in and select the "Master" realm
4. Select "Clients" from the side menu
5. Select the "security-admin-console" client from the list that appears
6. Change the "Valid Redirect URIs" from /auth/admin/master/console/* to /yourchange/auth/admin/master/console/*
7. Save and sign out. You'll again see the "Invalid redirect url" message after signing out.
8. Now, put in your original change <web-context>yourchange/auth</web-context> in standalone.xml Restart Keycloak and navigate to the login page (which is now /yourchange/auth/admin)
9. Log in and enjoy

Use PowerShell to do anything smarter for a DOS prompt. Here, I've shown how to batch rename all the files and directories in the current directory that contain spaces by replacing them with _ underscores.

Dir |
Rename-Item -NewName { $_.Name -replace " ","_" }

EDIT :
Optionally, the Where-Object command can be used to filter out ineligible objects for the successive cmdlet (command-let). The following are some examples to illustrate the flexibility it can afford you:

• To skip any document files

  Dir |
  Where-Object { $_.Name -notmatch "\.(doc|xls|ppt)x?$" } |
  Rename-Item -NewName { $_.Name -replace " ","_" }
  

• To process only directories (pre-3.0 version)

  Dir |
  Where-Object { $_.Mode -match "^d" } |
  Rename-Item -NewName { $_.Name -replace " ","_" }
  

  PowerShell v3.0 introduced new Dir flags. You can also use Dir -Directory there.

• To skip any files already containing an underscore (or some other character)

  Dir |
  Where-Object { -not $_.Name.Contains("_") } |
  Rename-Item -NewName { $_.Name -replace " ","_" }
  

Does this help you:

<script type="text/javascript">
window.onerror = function() {
    alert("Error caught");
};

xxx();
</script>

I'm not sure how it handles Flash errors though...

Update: it doesn't work in Opera, but I'm hacking Dragonfly right now to see what it gets. Suggestion about hacking Dragonfly came from this question:

Socks4 is a very simple protocol to implement. You listen for the initial connection, connect to the host/port that was requested by the client, send the success code to the client then forward the outgoing and incoming streams across sockets.

If you go with HTTP you'll have to read and possibly set/remove some HTTP headers so that's a little more work.

If I remember correctly, SSL will work across HTTP and Socks proxies. For a HTTP proxy you implement the CONNECT verb, which works much like the socks4 as described above, then the client opens the SSL connection across the proxied tcp stream.

It's not really a function, but it is an localised piece of code. Of course it doesn't pass the code just the result. It won't work if passed to an event dispatcher to be run at a later time (as the result is calculated now and not when the event occurs). But it does localise your code into one place if that is all you are trying to do.

#include <stdio.h>

int IncMultInt(int a, int b)
{
    a++;
    return a * b;
}

int main(int argc, char *argv[])

{
    int a = 5;
    int b = 7;

    printf("%d * %d = %d\n", a, b, IncMultInt(a, b));

    b = 9;

    // Create some local code with it's own local variable
    printf("%d * %d = %d\n", a, b,  ( { int _a = a+1; _a * b; } ) );

    return 0;
}

Here's an example:

package foo;

public class Test
{
    public static void main(String[] args)
    {
        ClassLoader loader = Test.class.getClassLoader();
        System.out.println(loader.getResource("foo/Test.class"));
    }
}

This printed out:

EDIT: Youtube renders the object and embed with no explicit wmode set, meaning it defaults to "window" which means it overlays everything. You need to either:

a) Host the page that contains the object/embed code yourself and add wmode="transparent" param element to object and attribute to embed if you choose to serve both elements

b) Find a way for youtube to specify those.

As answered above:

//Parent[@id='1']/Children/child/@name 

will only output the name attribute of the 4 child nodes belonging to the Parent specified by its predicate [@id=1]. You'll then need to change the predicate to [@id=2] to get the set of child nodes for the next Parent.

However, if you ignore the Parent node altogether and use:

//child/@name

you can select name attribute of all child nodes in one go.

name="Child_2"
name="Child_4"
name="Child_1"
name="Child_3"
name="Child_1"
name="Child_2"
name="Child_4"
name="Child_3"

Products are located mainly in the following tables:

• wp_posts table with post_type like product (or product_variation),

• wp_postmeta table with post_id as relational index (the product ID).

• wp_wc_product_meta_lookup table with product_id as relational index (the post ID) | Allow fast queries on specific product data (since WooCommerce 3.7)

• wp_wc_order_product_lookuptable with product_id as relational index (the post ID) | Allow fast queries to retrieve products on orders (since WooCommerce 3.7)

Product types, categories, subcategories, tags, attributes and all other custom taxonomies are located in the following tables:

• wp_terms

• wp_termmeta

• wp_term_taxonomy

• wp_term_relationships - column object_id as relational index (the product ID)

• wp_woocommerce_termmeta

• wp_woocommerce_attribute_taxonomies (for product attributes only)

• wp_wc_category_lookup (for product categories hierarchy only since WooCommerce 3.7)

Product types are handled by custom taxonomy product_type with the following default terms:

• simple
• grouped
• variable
• external

Some other product types for Subscriptions and Bookings plugins:

• subscription
• variable-subscription
• booking

Since Woocommerce 3+ a new custom taxonomy named product_visibility handle:

• The product visibility with the terms exclude-from-search and exclude-from-catalog
• The feature products with the term featured
• The stock status with the term outofstock
• The rating system with terms from rated-1 to rated-5

Particular feature: Each product attribute is a custom taxonomy…

The top answer is useful but I expanded on it a bit.

If you want to set the value of your file object (the f in as f) based on the arguments passed to open() here's one way to do it:

def save_arg_return_data(*args, **kwargs):
    mm = MagicMock(spec=file)
    mm.__enter__.return_value = do_something_with_data(*args, **kwargs)
    return mm
m = MagicMock()
m.side_effect = save_arg_return_array_of_data

# if your open() call is in the file mymodule.animals 
# use mymodule.animals as name_of_called_file
open_name = '%s.open' % name_of_called_file

with patch(open_name, m, create=True):
    #do testing here

Basically, open() will return an object and with will call __enter__() on that object.

To mock properly, we must mock open() to return a mock object. That mock object should then mock the __enter__() call on it (MagicMock will do this for us) to return the mock data/file object we want (hence mm.__enter__.return_value). Doing this with 2 mocks the way above allows us to capture the arguments passed to open() and pass them to our do_something_with_data method.

I passed an entire mock file as a string to open() and my do_something_with_data looked like this:

def do_something_with_data(*args, **kwargs):
    return args[0].split("\n")

This transforms the string into a list so you can do the following as you would with a normal file:

for line in file:
    #do action

Handmade dll's collection folder
If you solution has a garbage folder for dll-files from different libraries
lib, source, libs, etc.
You can get this trouble if you'll open your solution (for a firs time) in Visual Studio. And your dll's collecting folder is missed for somehow or a concrete dll-file is missed.

Visual Studio will try silently to substitute dll's reference for something on its own. If VS will succeed then a new reference will be persistent for your local solution. Not for other clones/checkouts.

I.e. your <HintPath> will be ignored and you project file (.csproj) will not be changed.
As an example of me

<Reference Include="DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\..\..\lib\DocumentFormat.OpenXml.dll</HintPath>
</Reference>

The DocumentFormat.OpenXml will be referenced from C:\Program Files (x86)\Open XML SDK\V2.5\lib not from a solution\..\lib folder.

fast Workaround

• check and restore you dll's collecting folder
• from Solution Explorer do Unload Project, then Reload Project.

right Workaround is to migrate to NuGet package manager.

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

I know this is an old thread, but - since it's not been mentioned this works

  Dictionary<string, object> LookUp = new Dictionary<string, object>();
  LookUp.Add("bob", new { age = "23", height = "2.1m", weight = "110kg"});
  LookUp.Add("jasper", new { age = "33", height = "1.75m", weight = "90kg"});
  foreach(KeyValuePair<string, object> entry in LookUp )
  {
      object person = entry.Value;
      Console.WriteLine("Person name:" + entry.Key + " Age: "  + person.age);          
  }

You should put this line in your application context:

<context:component-scan base-package="com.cinebot.service" />

Read more about Automatically detecting classes and registering bean definitions in documentation.

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

The problem you're having stems from the fact that you're missing android:dividerHeight, which you need, and the fact that you're trying to specify a line weight in your drawable, which you can't do with dividers for some odd reason. Essentially to get your example to work you could do something like the following:

Create your drawable as either a rectangle or a line, either works you just can't try to set any dimensions on it, so either:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line">
     <stroke android:color="#8F8F8F" android:dashWidth="1dp" android:dashGap="1dp" />
</shape>

OR:

<shape xmlns:android="http://schemas.android.com/apk/res/android"  android:shape="rectangle">
     <solid android:color="#8F8F8F"/>
</shape>

Then create a custom style (just a preference but I like to be able to reuse stuff)

<style name="dividedListStyle" parent="@android:style/Widget.ListView">
    <item name="android:cacheColorHint">@android:color/transparent</item>
    <item name="android:divider">@drawable/list_divider</item>
    <item name="android:dividerHeight">1dp</item>
</style>

Finally declare your list view using the custom style:

<ListView
     style="@style/dividedListStyle"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:id="@+id/cashItemsList">
</ListView>

I'm assuming you know how to use these snippets, if not let me know. Basically the answer to your question is that you can't set the divider thickness in the drawable, you have to leave the width undefined there and use android:dividerHeight to set it instead.

You can use group by for display distinct values and also corresponding fields.

select * from tabel_name group by FirstName

Now you got output like this:

ID    FirstName     LastName
2     Bugs          Bunny
1     John          Doe

If you want to answer like

ID    FirstName     LastName
1     John          Doe
2     Bugs          Bunny

then use this query,

select * from table_name group by FirstName order by ID

This code resets the defaults to the registration domain:

[[NSUserDefaults standardUserDefaults] setPersistentDomain:[NSDictionary dictionary] forName:[[NSBundle mainBundle] bundleIdentifier]];

In other words, it removeObjectForKey for every single key you ever registered in that app.

A more general approach would be to set the UIView's appearance's tintColor.

UIColor *myColor = [UIColor purpleColor];
[[UIView appearance] setTintColor:myColor];

Makes sense if you're using many default UI elements.

Looks like you're trying to both inherit the groupId from the parent, and simultaneously specify the parent using an inherited groupId!

In the child pom, use something like this:

<modelVersion>4.0.0</modelVersion>

<parent>
  <groupId>org.felipe</groupId>
  <artifactId>tutorial_maven</artifactId>
  <version>1.0-SNAPSHOT</version>
  <relativePath>../pom.xml</relativePath>
</parent>

<artifactId>tutorial_maven_jar</artifactId>

Using properties like ${project.groupId} won't work there. If you specify the parent in this way, then you can inherit the groupId and version in the child pom. Hence, you only need to specify the artifactId in the child pom.

You can get it one line like this: String monthName = new DataFormatSymbols.getMonths()[cal.get(Calendar.MONTH)]

Adding to Eric's answer, you can also configure this in the csproj file:

<ItemGroup>
    <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
      <_Parameter1>MyTests</_Parameter1>
    </AssemblyAttribute>
</ItemGroup>

Or if you have one test project per project to be tested, you could do something like this in your Directory.Build.props file:

<ItemGroup>
    <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
      <_Parameter1>$(MSBuildProjectName).Test</_Parameter1>
    </AssemblyAttribute>

Using Guava

List<Object> lst ...    
List<String> ls = Lists.transform(lst, Functions.toStringFunction());

The compiler isn't smart enough to know that <, >, and == are a "complete set". You can let it know that by removing the condition "if(val == sorted[mid])" -- it's redundant. Jut say "else return mid;"

If you are using the windows CMD you can use this command to create a database using sqlite3

C:\sqlite3.exe DBNAME.db ".read DBSCRIPT.sql"

If you haven't a database with that name sqlite3 will create one, and if you already have one, it will run it anyways but with the "TABLENAME already exists" error, I think you can also use this command to change an already existing database (but im not sure)

You could also change resolution of your bluestacks emulator. For example from 800x1280 to 1280x800

Here are instructions for how to change the screen resolution.

To change screen resolution in BlueStacks Android emulator you need to edit two registry items:

1. Run regedit.exe

2. Set new resolution (in decimal):

HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0\Height

and

HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0\Width

Kill all BlueStacks processes.

Restart BlueStacks

The others have already said that methods in onClick are searched in activities, not fragments. Nevertheless, if you really want it, it is possible.

Basically, each view has a tag (probably null). We set the root view's tag to the fragment that inflated that view. Then, it is easy to search the view parents and retrieve the fragment containing the clicked button. Now, we find out the method name and use reflection to call the same method from the retrieved fragment. Easy!

in a class that extends Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_id, container, false);

    OnClickFragments.registerTagFragment(rootView, this); // <========== !!!!!

    return rootView;
}

public void onButtonSomething(View v) {
    Log.d("~~~","~~~ MyFragment.onButtonSomething");
    // whatever
}

all activities are derived from the same ButtonHandlingActivity:

public class PageListActivity extends ButtonHandlingActivity

ButtonHandlingActivity.java:

public class ButtonHandlingActivity extends Activity {

    public void onButtonSomething(View v) {
        OnClickFragments.invokeFragmentButtonHandlerNoExc(v);
//or, if you want to handle exceptions:
//      try {
//          OnClickFragments.invokeFragmentButtonHandler(v);
//      } catch ...
    }

}

It has to define methods for all xml onClick handlers.

com/example/customandroid/OnClickFragments.java:

package com.example.customandroid;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import android.app.Fragment;
import android.view.View;

public abstract class OnClickFragments {
    public static class FragmentHolder {
        Fragment fragment;
        public FragmentHolder(Fragment fragment) {
            this.fragment = fragment;
        }
    }
    public static Fragment getTagFragment(View view) {
        for (View v = view; v != null; v = (v.getParent() instanceof View) ? (View)v.getParent() : null) {
            Object tag = v.getTag();
            if (tag != null && tag instanceof FragmentHolder) {
                return ((FragmentHolder)tag).fragment;
            }
        }
        return null;
    }
    public static String getCallingMethodName(int callsAbove) {
        Exception e = new Exception();
        e.fillInStackTrace();
        String methodName = e.getStackTrace()[callsAbove+1].getMethodName();
        return methodName;
    }
    public static void invokeFragmentButtonHandler(View v, int callsAbove) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
        String methodName = getCallingMethodName(callsAbove+1);
        Fragment f = OnClickFragments.getTagFragment(v);
        Method m = f.getClass().getMethod(methodName, new Class[] { View.class });
        m.invoke(f, v);
    }
    public static void invokeFragmentButtonHandler(View v) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
        invokeFragmentButtonHandler(v,1);
    }
    public static void invokeFragmentButtonHandlerNoExc(View v) {
        try {
            invokeFragmentButtonHandler(v,1);
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
    }
    public static void registerTagFragment(View rootView, Fragment fragment) {
        rootView.setTag(new FragmentHolder(fragment));
    }
}

And the next adventure will be proguard obfuscation...

PS

It is of course up to you to design your application so that the data live in the Model rather than in Activities or Fragments (which are Controllers from the MVC, Model-View-Controller point of view). The View is what you define via xml, plus the custom view classes (if you define them, most people just reuse what already is). A rule of thumb: if some data definitely must survive the screen turn, they belong to Model.

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

I found a little utility function a while back and I've been using it for resetting my form elements ever since (source: http://www.learningjquery.com/2007/08/clearing-form-data):

function clearForm(form) {
  // iterate over all of the inputs for the given form element
  $(':input', form).each(function() {
    var type = this.type;
    var tag = this.tagName.toLowerCase(); // normalize case
    // it's ok to reset the value attr of text inputs, 
    // password inputs, and textareas
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = "";
    // checkboxes and radios need to have their checked state cleared 
    // but should *not* have their 'value' changed
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    // select elements need to have their 'selectedIndex' property set to -1
    // (this works for both single and multiple select elements)
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

... or as a jQuery plugin...

$.fn.clearForm = function() {
  return this.each(function() {
    var type = this.type, tag = this.tagName.toLowerCase();
    if (tag == 'form')
      return $(':input',this).clearForm();
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = '';
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

Brief code but full-featured

The following is a hybrid jQuery solution that formats each data "record" into an HTML element and uses the data's properties as HTML attribute values.

The jquery each runs the inner loop; I needed the regular JavaScript for on the outer loop to be able to grab the property name (instead of value) for display as the heading. According to taste it can be modified for slightly different behaviour.

This is only 5 main lines of code but wrapped onto multiple lines for display:

$.get("data.php", function(data){

    for (var propTitle in data) {

        $('<div></div>') 
            .addClass('heading')
            .insertBefore('#contentHere')
            .text(propTitle);

            $(data[propTitle]).each(function(iRec, oRec) {

                $('<div></div>')
                    .addClass(oRec.textType)
                    .attr('id', 'T'+oRec.textId)
                    .insertBefore('#contentHere')
                    .text(oRec.text);
            });
    }

});

Produces the output

(Note: I modified the JSON data text values by prepending a number to ensure I was displaying the proper records in the proper sequence - while "debugging")

<div class="heading">
    justIn
</div>
<div id="T123" class="Greeting">
    1Hello
</div>
<div id="T514" class="Question">
    1What's up?
</div>
<div id="T122" class="Order">
    1Come over here
</div>
<div class="heading">
    recent
</div>
<div id="T1255" class="Greeting">
    2Hello
</div>
<div id="T6564" class="Question">
    2What's up?
</div>
<div id="T0192" class="Order">
    2Come over here
</div>
<div class="heading">
    old
</div>
<div id="T5213" class="Greeting">
    3Hello
</div>
<div id="T9758" class="Question">
    3What's up?
</div>
<div id="T7655" class="Order">
    3Come over here
</div>
<div id="contentHere"></div>

Apply a style sheet

<style>
.heading { font-size: 24px; text-decoration:underline }
.Greeting { color: green; }
.Question { color: blue; }
.Order { color: red; }
</style>

to get a "beautiful" looking set of data

More Info
The JSON data was used in the following way:

for each category (key name the array is held under):

• the key name is used as the section heading (e.g. justIn)

for each object held inside an array:

• 'text' becomes the content of a div
• 'textType' becomes the class of the div (hooked into a style sheet)
• 'textId' becomes the id of the div
• e.g. <div id="T122" class="Order">Come over here</div>

UPDATE
    `table1` AS `dest`,
    (
        SELECT
            *
        FROM
            `table2`
        WHERE
            `id` = x
    ) AS `src`
SET
    `dest`.`col1` = `src`.`col1`
WHERE
    `dest`.`id` = x
;

Hope this works for you.

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:

<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

While this will not (note the leading space before the opening <? tag)

 <?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

Also, this will not work either (the echo will break it):

<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.

add ob_start (); at the top and at the end add ob_end_flush();

<?php
    ob_start();
    require('fpdf.php');
    $pdf = new FPDF();
    $pdf->AddPage();
    $pdf->SetFont('Arial','B',16);
    $pdf->Cell(40,10,'Hello World!');
    $pdf->Output();
    ob_end_flush(); 
?>

give me an error as below:
FPDF error: Some data has already been output, can't send PDF

to over come this error: go to fpdf.php in that,goto line number 996

function Output($name='', $dest='')

after that make changes like this:

function Output($name='', $dest='') {   
    ob_clean();     //Output PDF to so

Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.

<?

while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);

?>

cheers :-)

In my case i had set:

ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);

When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off the display_errors option, the report was generated successfully.

There is an open source offline package deployer for Windows which I wrote:

You can try this out to see if it meets your needs.

It is better to use onchange(event) with <select>. With <input> you can use below event:

- onkeyup(event)
- onkeydown(event)
- onkeypress(event)

curl -s -v -o/dev/null -H "Testheader: test" http://www.example.com

You could also use -I option if you want to send a HEAD request and not a GET request.

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100, say, and your current client IDs are in Sheet1 in Column A.

What you would do is:

1. Select the whole data table you want conditionally formatted in Sheet1
2. Click Conditional Formatting > New Rule > Use a Formula to determine which cells to format
3. In the formula bar, type in =ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0)) and select how you want those rows formatted

And that should do the trick.

You may use Floyd's tortoise algorithm as suggested in above answers as well.

This algorithm can check if a singly linked list has a closed cycle. This can be achieved by iterating a list with two pointers that will move in different speed. In this way, if there is a cycle the two pointers will meet at some point in the future.

Please feel free to check out my blog post on the linked lists data structure, where I also included a code snippet with an implementation of the above-mentioned algorithm in java language.

Here's how to determine a local user:

    public bool IsLocalUser()
    {
        return windowsIdentity.AuthenticationType == "NTLM";
    }

Edit by Ian Boyd

You should not use NTLM anymore at all. It is so old, and so bad, that Microsoft's Application Verifier (which is used to catch common programming mistakes) will throw a warning if it detects you using NTLM.

Here's a chapter from the Application Verifier documentation about why they have a test if someone is mistakenly using NTLM:

Why the NTLM Plug-in is Needed

NTLM is an outdated authentication protocol with flaws that potentially compromise the security of applications and the operating system. The most important shortcoming is the lack of server authentication, which could allow an attacker to trick users into connecting to a spoofed server. As a corollary of missing server authentication, applications using NTLM can also be vulnerable to a type of attack known as a “reflection” attack. This latter allows an attacker to hijack a user’s authentication conversation to a legitimate server and use it to authenticate the attacker to the user’s computer. NTLM’s vulnerabilities and ways of exploiting them are the target of increasing research activity in the security community.

Although Kerberos has been available for many years many applications are still written to use NTLM only. This needlessly reduces the security of applications. Kerberos cannot however replace NTLM in all scenarios – principally those where a client needs to authenticate to systems that are not joined to a domain (a home network perhaps being the most common of these). The Negotiate security package allows a backwards-compatible compromise that uses Kerberos whenever possible and only reverts to NTLM when there is no other option. Switching code to use Negotiate instead of NTLM will significantly increase the security for our customers while introducing few or no application compatibilities. Negotiate by itself is not a silver bullet – there are cases where an attacker can force downgrade to NTLM but these are significantly more difficult to exploit. However, one immediate improvement is that applications written to use Negotiate correctly are automatically immune to NTLM reflection attacks.

By way of a final word of caution against use of NTLM: in future versions of Windows it will be possible to disable the use of NTLM at the operating system. If applications have a hard dependency on NTLM they will simply fail to authenticate when NTLM is disabled.

How the Plug-in Works

The Verifier plug detects the following errors:

• The NTLM package is directly specified in the call to AcquireCredentialsHandle (or higher level wrapper API).

• The target name in the call to InitializeSecurityContext is NULL.

• The target name in the call to InitializeSecurityContext is not a properly-formed SPN, UPN or NetBIOS-style domain name.

The latter two cases will force Negotiate to fall back to NTLM either directly (the first case) or indirectly (the domain controller will return a “principal not found” error in the second case causing Negotiate to fall back).

The plug-in also logs warnings when it detects downgrades to NTLM; for example, when an SPN is not found by the Domain Controller. These are only logged as warnings since they are often legitimate cases – for example, when authenticating to a system that is not domain-joined.

NTLM Stops

5000 – Application Has Explicitly Selected NTLM Package

Severity – Error

The application or subsystem explicitly selects NTLM instead of Negotiate in the call to AcquireCredentialsHandle. Even though it may be possible for the client and server to authenticate using Kerberos this is prevented by the explicit selection of NTLM.

How to Fix this Error

The fix for this error is to select the Negotiate package in place of NTLM. How this is done will depend on the particular Network subsystem being used by the client or server. Some examples are given below. You should consult the documentation on the particular library or API set that you are using.

APIs(parameter) Used by Application    Incorrect Value  Correct Value  
=====================================  ===============  ========================
AcquireCredentialsHandle (pszPackage)  “NTLM”           NEGOSSP_NAME “Negotiate”

If you do not want to specify a message with your stashed changes, pass the filename after a double-dash.

$ git stash -- filename.ext

If it's an untracked/new file, you will have to stage it first.

This method works in git versions 2.13+

This link works with me: video

The answer posted before didn't work for me until the second click

So what I did is Directly call:

        new NewForm().setVisible(true);

        this.dispose();//to close the current jframe

If you wanted to search some elements based on a regex, you can use the filter function. For example, say you wanted to make sure that in all the input boxes, the user has only entered numbers, so let's find all the inputs which don't match and highlight them.

$("input:text")
    .filter(function() {
        return this.value.match(/[^\d]/);
    })
    .addClass("inputError")
;

Of course if it was just something like this, you could use the form validation plugin, but this method could be applied to any sort of elements you like. Another example to show what I mean: Find all the elements whose id matches /[a-z]+_\d+/

$("[id]").filter(function() {
    return this.id.match(/[a-z]+_\d+/);
});

you want after days find date this code try..

public Date getToDateAfterDays(Integer day) {
        Date nowdate = new Date();
        Calendar cal = Calendar.getInstance();
        cal.setTime(nowdate);
        cal.add(Calendar.DATE, day);
        return cal.getTime();
    }

The file location/path has to relative to your classpath locations. If resources directory is in your classpath you just need "app-context.xml" as file location.

To avoid getting the warning in a push navigation, you can directly use :

[self.view.window.rootViewController presentViewController:viewController animated:YES completion:nil];

And then in your modal view controller, when everything is finished, you can just call :

[self dismissViewControllerAnimated:YES completion:nil];

I was having problems here (i.e. sending form-data whilst uploading a file) until I used the following:

files = {'file': (filename, open(filepath, 'rb'), 'text/xml'),
         'Content-Disposition': 'form-data; name="file"; filename="' + filename + '"',
         'Content-Type': 'text/xml'}

That's the input that ended up working for me. In Chrome Dev Tools -> Network tab, I clicked the request I was interested in. In the Headers tab, there's a Form Data section, and it showed both the Content-Disposition and the Content-Type headers being set there.

I did NOT need to set headers in the actual requests.post() command for this to succeed (including them actually caused it to fail)

You can use a .Net environment Visual studio, Take a look at the differences with the PC version.

A lighter editor would be Visual Code

Alternatives :

1. Installing the Mono Project runtime . It allows you to re-compile the code and run it on a Mac, but this requires various alterations to the codebase, as the fuller .Net Framework is not available. (Also, WPF applications aren't supported here either.)

2. Virtual machine (VMWare Fusion perhaps)

3. Update your codebase to .Net Core, (before choosing this option take a look at this migration process)

   • .Net Core 3.1 is an open-source, free and available on Window, MacOs and Linux

   • As of September 14, a release candidate ¹ of .Net Core 5.0 has been deployed on Window, MacOs and Linux.

Yes, it is possible.

There is a perfect open-source Python (.PYC) decompiler, called Decompyle++ https://github.com/zrax/pycdc/

Decompyle++ aims to translate compiled Python byte-code back into valid and human-readable Python source code. While other projects have achieved this with varied success, Decompyle++ is unique in that it seeks to support byte-code from any version of Python.

None of the answers above, at least to me, show how to actually handle determining whether you have 1 item or multiple, and how to actually get the values out of your items in a generic way that doesn't depend on there actually only being one item, or multiple, so I'm throwing my hat in the ring.

This is quite easily and generically done by checking your count to see that you have at least one item, then doing a foreach loop on the .SelectedItems, casting each item as a DataRowView:

if (listView1.SelectedItems.Count > 0)
{
     foreach (DataRowView drv in listView1.SelectedItems)
     {
         string firstColumn = drv.Row[0] != null ? drv.Row[0].ToString() : String.Empty;
         string secondColumn = drv.Row[1] != null ? drv.Row[1].ToString() : String.Empty;
         // ... do something with these values before they are replaced
         // by the next run of the loop that will get the next row
     }
}

This will work, whether you have 1 item or many. It's funny that MSDN says to use ListView.SelectedListViewItemCollection to capture listView1.SelectedItems and iterate through that, but I found that this gave an error in my WPF app: The type name 'SelectedListViewItemCollection' does not exist in type 'ListView'.

Yup, when you do gem install, it will search the current directory first, so if your .gem file is there, it will pick it up. I found it on the gem reference, which you may find handy as well:

gem install will install the named gem. It will attempt a local installation (i.e. a .gem file in the current directory), and if that fails, it will attempt to download and install the most recent version of the gem you want.

This can achieve using two SQL functions- SUBSTRING and CHARINDEX

You can read strings to a variable as shown in the above answers, or can add it to a SELECT statement as below:

SELECT SUBSTRING('Net Operating Loss - 2007' ,0, CHARINDEX('-','Net Operating Loss - 2007'))

Of course, if you don't need really floating-point arithmetic, just arithmetic on e.g. dollar values where there are always exactly two decimal digits, you might just drop the dot (effectively multiplying by 100) and compare the resulting integers.

if [[ $((10#${num1/.})) < $((10#${num2/.})) ]]; then
    ...

This obviously requires you to be sure that both values have the same number of decimal places.

from django.utils import simplejson 
from django.core import serializers 

def pagina_json(request): 
   misdatos = misdatos.objects.all()
   data = serializers.serialize('json', misdatos) 
   return HttpResponse(data, mimetype='application/json')

// image from res/drawable
    int resID = getResources().getIdentifier("my_image", 
            "drawable", getPackageName());
// view
    int resID = getResources().getIdentifier("my_resource", 
            "id", getPackageName());

Use the Apache XMLSerializer

here's an example: http://www.informit.com/articles/article.asp?p=31349&seqNum=3&rl=1

you can check this as well

http://www.netomatix.com/XmlFileToString.aspx

For the sake of completeness -- just because none of the previous answers mentioned this method -- if you are working with Node.js and don't have to care about browser compatibility, the desired effect is pretty easy to achieve with the built in inherits of the util module (official docs here).

For example, let's suppose you want to create a custom error class that takes an error code as the first argument and the error message as the second argument:

file custom-error.js:

'use strict';

var util = require('util');

function CustomError(code, message) {
  Error.captureStackTrace(this, CustomError);
  this.name = CustomError.name;
  this.code = code;
  this.message = message;
}

util.inherits(CustomError, Error);

module.exports = CustomError;

Now you can instantiate and pass/throw your CustomError:

var CustomError = require('./path/to/custom-error');

// pass as the first argument to your callback
callback(new CustomError(404, 'Not found!'));

// or, if you are working with try/catch, throw it
throw new CustomError(500, 'Server Error!');

Note that, with this snippet, the stack trace will have the correct file name and line, and the error instance will have the correct name!

This happens due to the usage of the captureStackTrace method, which creates a stack property on the target object (in this case, the CustomError being instantiated). For more details about how it works, check the documentation here.

If you are okay with just having IE open the JSON into a notepad, you can change your system's default program for .json files to Notepad.

To do this, create or find a .json file, right mouse click, and select "Open With" or "Choose Default Program."

This might come in handy if you by chance want to use Internet Explorer but your IT company wont let you edit your registry. Otherwise, I recommend the above answers.

The following code allows to upload gif, png, jpg, jpeg and bmp files.

var extension = $('#your_file_id').val().split('.').pop().toLowerCase();

if($.inArray(extension, ['gif','png','jpg','jpeg','bmp']) == -1) {
    alert('Sorry, invalid extension.');
    return false;
}

2. right click on highlighted element tag, choose Copy ? Copy XPath.

Telescoping Constructor Pattern

Analogy:

• Factory: Consider a restaurant. The creation of "today's meal" is a factory pattern, because you tell the kitchen "get me today's meal" and the kitchen (factory) decides what object to generate, based on hidden criteria.
• Builder: The builder appears if you order a custom pizza. In this case, the waiter tells the chef (builder) "I need a pizza; add cheese, onions and bacon to it!" Thus, the builder exposes the attributes the generated object should have, but hides how to set them.

The following can be used from numpy:

import numpy as np 
image = np.array(image)

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

After some research I have found method that doesn't require maven or any 3rd party extension/program.

You can use "Class-Path" in your manifest file.

For example:

Create manifest file MANIFEST.MF

Manifest-Version: 1.0
Created-By: Bundle
Class-Path: ./custom_lib.jar
Main-Class: YourMainClass

Compile all your classes and run jar cfm Testing.jar MANIFEST.MF *.class custom_lib.jar

c stands for create archive f indicates that you want to specify file v is for verbose input m means that we will pass custom manifest file

Be sure that you included lib in jar package. You should be able to run jar in the normal way.

based on: http://www.ibm.com/developerworks/library/j-5things6/

all other information you need about the class-path do you find here

To upgrade Ruby with rbenv: Per the rbenv README

• Update first: brew upgrade rbenv ruby-build
• See list of Ruby versions: versions available: rbenv install -l
• Install: rbenv install <selected version>

I solved this problem with:

inputObj.css('cssText', inputObj.attr('style')+'padding-left: ' + (width + 5) + 'px !IMPORTANT;');

So no inline-Style is lost, an the last overrides the first

I suggest using Boost's static assert feature in concert with is_base_of from the Boost Type Traits library:

template<typename T>
class ObservableList {
    BOOST_STATIC_ASSERT((is_base_of<List, T>::value)); //Yes, the double parentheses are needed, otherwise the comma will be seen as macro argument separator
    ...
};

In some other, simpler cases, you can simply forward-declare a global template, but only define (explicitly or partially specialise) it for the valid types:

template<typename T> class my_template;     // Declare, but don't define

// int is a valid type
template<> class my_template<int> {
    ...
};

// All pointer types are valid
template<typename T> class my_template<T*> {
    ...
};

// All other types are invalid, and will cause linker error messages.

[Minor EDIT 6/12/2013: Using a declared-but-not-defined template will result in linker, not compiler, error messages.]

In my case, this error:

Video format or MIME type is not supported.

Was due to the CSP in my .htaccess that did not allow the content to be loaded. You can check this by opening the browser's console and refreshing the page.

Once I added the domain that was hosting the video in the media-src part of that CSP, the console was clean and the video was loaded properly. Example:

Content-Security-Policy: default-src 'none'; media-src https://myvideohost.domain; script-src 'self'; style-src 'unsafe-inline' 'self'

Not trying to be smart about it, but if you use Sublime Text for your editor, the steps are:

1. Select the block
2. cmd+/ on Mac or ctrl+/ on Linux & Windows
3. Profit

I'd imagine that other editors have similar functionality too. Which one are you using? I'd be happy to do some digging.

Just a necrocomment for using string.Join and LINQ.

ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
dlgOpenMockImage.Filter = string.Format("{0}| All image files ({1})|{1}|All files|*", 
    string.Join("|", codecs.Select(codec => 
    string.Format("{0} ({1})|{1}", codec.CodecName, codec.FilenameExtension)).ToArray()),
    string.Join(";", codecs.Select(codec => codec.FilenameExtension).ToArray()));

Here are some examples from this blog mentioned earlier:

<configuration>    
   <Database>    
      <add key="ConnectionString" value="data source=.;initial catalog=NorthWind;integrated security=SSPI"/>    
   </Database>    
</configuration>  

get values:

 NameValueCollection db = (NameValueCollection)ConfigurationSettings.GetConfig("Database");         
    labelConnection2.Text = db["ConnectionString"];

-

Another example:

<Locations 
   ImportDirectory="C:\Import\Inbox"
   ProcessedDirectory ="C:\Import\Processed"
   RejectedDirectory ="C:\Import\Rejected"
/>

get value:

Hashtable loc = (Hashtable)ConfigurationSettings.GetConfig("Locations"); 

labelImport2.Text = loc["ImportDirectory"].ToString();
labelProcessed2.Text = loc["ProcessedDirectory"].ToString();

string[] strarr = {"ram","mohan","sita"};

#include <string>
std::string strarr = { "ram", "mohan", "sita" };

or

const char* strarr[] = { "ram", "mohan", "sita" };

foreach(string str in strarr) { listbox.items.add(str); }

for (int i = 0; i < sizeof strarr / sizeof *strarr; ++i)
    listbox.items.add(strarr[i]);

Note: you can also put the strings into a std::vector rather than an array:

std::vector<std::string> strvec;
strvec.push_back("ram");
strvec.push_back("mohan");
strvec.push_back("sita");

for (std::vector<std::string>::const_iterator i = strvec.begin(); i != strvec.end(); ++i)
    listbox.items.add(*i);

This is another solution:

if os.path.isfile(os.path.join(path, filename)):
    os.remove(os.path.join(path, filename))

Doing Project->Clean… in Eclipse solved this problem for me.

Here's another way to force a type-cast even between incompatible types and interfaces where TS compiler normally complains:

export function forceCast<T>(input: any): T {

  // ... do runtime checks here

  // @ts-ignore <-- forces TS compiler to compile this as-is
  return input;
}

Then you can use it to force cast objects to a certain type:

import { forceCast } from './forceCast';

const randomObject: any = {};
const typedObject = forceCast<IToDoDto>(randomObject);

Note that I left out the part you are supposed to do runtime checks before casting for the sake of reducing complexity. What I do in my project is compiling all my .d.ts interface files into JSON schemas and using ajv to validate in runtime.

If anyone is specifically getting Unexpected token <, and your package.json is fine, check your npm-shrinkwrap.json file! I had unresolved merge issues in mine, and fixing that resolved everything.

It might be worth looking at a tutorial: MDN Canvas Tutorial

You can get the width and height of a canvas element simply by accessing those properties of the element. For example:

var canvas = document.getElementById('mycanvas');
var width = canvas.width;
var height = canvas.height;

If the width and height attributes are not present in the canvas element, the default 300x150 size will be returned. To dynamically get the correct width and height use the following code:

const canvasW = canvas.getBoundingClientRect().width;
const canvasH = canvas.getBoundingClientRect().height;

Or using the shorter object destructuring syntax:

const { width, height } = canvas.getBoundingClientRect();

The context is an object you get from the canvas to allow you to draw into it. You can think of the context as the API to the canvas, that provides you with the commands that enable you to draw on the canvas element.

I don't see any mention of flexbox in here, so I will illustrate:

HTML

 <div class="wrapper">
   <div class="main">top</div>
   <div class="footer">bottom</div>
 </div>

CSS

 .wrapper {
   display: flex;
   flex-direction: column;
   min-height: 100vh;
  }
 .main {
   flex: 1;
 }
 .footer {
  flex: 0;
 }

There should be one - and preferably only one - obvious way to do it.

Therefore list(dictionary.values()) is the one way.

Yet, considering Python3, what is quicker?

[*L] vs. [].extend(L) vs. list(L)

small_ds = {x: str(x+42) for x in range(10)}
small_df = {x: float(x+42) for x in range(10)}

%timeit [].extend(small_ds.values())
%timeit list(small_ds.values())

%timeit [].extend(small_df.values())
%timeit list(small_df.values())

big_ds = {x: str(x+42) for x in range(1000000)}
big_df = {x: float(x+42) for x in range(1000000)}

print('Big Dict(str)')
%timeit [*big_ds.values()]
%timeit [].extend(big_ds.values())
%timeit list(big_ds.values())

print('Big Dict(float)')
%timeit [*big_df.values()]
%timeit [].extend(big_df.values())
%timeit list(big_df.values())

# Name                    Version                   Build
ipython                   7.5.0            py37h24bf2e0_0

The result

1. For small dictionaries * operator is quicker
2. For big dictionaries where it matters list() is maybe slightly quicker

Hint 1: You might want to study the Python code in the bisect module.

Hint 2: Slicing can be used for list insertion:

>>> s = ['a', 'b', 'd', 'e']
>>> s[2:2] = ['c']
>>> s
['a', 'b', 'c', 'd', 'e']

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

Yes, anonymous inner classes is definitely one of the advantages of Java.

With an anonymous inner class you have access to final and member variables of the surrounding class, and that comes in handy in listeners etc.

But a major advantage is that the inner class code, which is (at least should be) tightly coupled to the surrounding class/method/block, has a specific context (the surrounding class, method, and block).

After some testing this WILL remove the background color when deselected or cell is tapped a second time when table view Selection is set to "Multiple Selection". Also works when table view Style is set to "Grouped".

extension ViewController: UITableViewDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if let cell = tableView.cellForRow(at: indexPath) {
            cell.contentView.backgroundColor = UIColor.darkGray
        }
    }
}

Note: In order for this to work as you see below, your cell's Selection property can be set to anything BUT None.

How it looks with different options

Style: Plain, Selection: Single Selection

Style: Plain, Selection: Multiple Selection

Style: Grouped, Selection: Multiple Selection

Bonus - Animation

For a smoother color transition, try some animation:

extension ViewController: UITableViewDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if let cell = tableView.cellForRow(at: indexPath) {
            UIView.animate(withDuration: 0.3, animations: {
                cell.contentView.backgroundColor = UIColor.darkGray
            })
        }
    }
}

Bonus - Text and Image Changing

You may notice the icon and text color also changing when cell is selected. This happens automatically when you set the UIImage and UILabel Highlighted properties

UIImage

1. Supply two colored images:

2. Set the Highlighted image property:

UILabel

Just supply a color for the Highlighted property:

You could probably use a set object instead. Just add numbers to the set. They inherently do not replicate.

This question is already answered, but for the benefit of others looking at this question I'd like to add the following suggestion: Instead of doing the slicing yourself as suggested above you might also use strptime() which is (IMHO) easier to read and perhaps the preferred way to do this conversion.

Below code for an uploading a single file at a time. This is correct and perfect to upload a single file. Read all commented instructions and follow the code. Definitely, it is worked.

public function upload_file() {
    ***// Upload folder location***
    $config['upload_path'] = './public/upload/';

    ***// Allowed file type***
    $config['allowed_types'] = 'jpg|jpeg|png|pdf';

    ***// Max size, i will set 2MB***
    $config['max_size'] = '2024';

    $config['max_width'] = '1024';
    $config['max_height'] = '768';

    ***// load upload library***            
    $this->load->library('upload', $config);

    ***// do_upload is the method, to send the particular image and file on that 
       // particular 
       // location that is detail in $config['upload_path']. 
       // In bracks will set name upload, here you need to set input name attribute 
       // value.***

    if($this->upload->do_upload('upload')) {
       $data = $this->upload->data();
       $post['upload'] = $data['file_name'];
    } else {
      $error = array('error' => $this->upload->display_errors());
    }
 }

From NumberKeyListener source code. This method they use to check if char is contained in defined array of accepted characters:

protected static boolean ok(char[] accept, char c) {
    for (int i = accept.length - 1; i >= 0; i--) {
        if (accept[i] == c) {
            return true;
        }
    }

    return false;
}

It is similar to @ÓscarLópez solution. Might be a bit faster cause of absence of foreach iterator.

The quick and dirty way would be to simple bind to the keyup event.

$('#mytxt').keyup(function(){_x000D_
    $('#divlen').text('you typed ' + this.value.length + ' characters');_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<input type=text id=mytxt >_x000D_
<div id=divlen></div>

But better would be to bind a reusable function to several events. For example also to the change(), so you can also anticipate text changes such as pastes (with the context menu, shortcuts would also be caught by the keyup )

You can create a new db then use the "Restore Wizard" enabling the Overwrite option or;

View the content;

RESTORE FILELISTONLY FROM DISK='c:\your.bak'

note the logical names of the .mdf & .ldf from the results, then;

RESTORE DATABASE MyTempCopy FROM DISK='c:\your.bak'
WITH 
   MOVE 'LogicalNameForTheMDF' TO 'c:\MyTempCopy.mdf',
   MOVE 'LogicalNameForTheLDF' TO 'c:\MyTempCopy_log.ldf'

To create the database MyTempCopy with the contents of your.bak.

Example (restores a backup of a db called 'creditline' to 'MyTempCopy';

RESTORE FILELISTONLY FROM DISK='e:\mssql\backup\creditline.bak'

>LogicalName
>--------------
>CreditLine
>CreditLine_log

RESTORE DATABASE MyTempCopy FROM DISK='e:\mssql\backup\creditline.bak'
WITH 
   MOVE 'CreditLine' TO 'e:\mssql\MyTempCopy.mdf',
   MOVE 'CreditLine_log' TO 'e:\mssql\MyTempCopy_log.ldf'

Already answered by @AjaxLeung, but in comments and hard to find.
For check only

lst.stream()
    .filter(x -> x > 5)
    .findFirst()
    .isPresent()

is simplified to

lst.stream()
    .anyMatch(x -> x > 5)

Solution for me (Android Studio) :

1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure

2) and increase the level of SDK "Compile SDK Version".

(since I ran into this today)

Be careful when using ES2015 fat arrow syntax:

This will fail :

it('accesses the network', done => {

  this.timeout(500); // will not work

  // *this* binding refers to parent function scope in fat arrow functions!
  // i.e. the *this* object of the describe function

  done();
});

EDIT: Why it fails:

As @atoth mentions in the comments, fat arrow functions do not have their own this binding. Therefore, it's not possible for the it function to bind to this of the callback and provide a timeout function.

Bottom line: Don't use arrow functions for functions that need an increased timeout.

I found the root cause is when you install the nuget packages through the UI the scripts won't run sometimes. So I'd recommend open Output view while you do that. If you don't see the license agreement window when installing Nuget, there is a better change your IDE isn't doing the job right. So that's why a restart, cleanup and rebuild helps!

PS: That adding anything under System.Data.Entity.* helps because, that triggers the Nuget installer to work properly. But this I found a quite unreliable way.

So just watch the output window, you MUST see something like a successful nuget installation message at the end. Most the time when there an issue, Nuget installer won't even kick off. That's when your restart of IDE is going to help.

When things go well, Nuget package manager and IDE (I used Installer term above) would do the change, compile the solution and keep you happy! But when its not give a little help by restarting IDE and watching that Output window!

7 (best solution)

 from numpy import*
 import matplotlib.pyplot as plt
 X = linspace(-pi, pi, 1000)

class Crtaj:

    def nacrtaj(self,x,y):
         self.x=x
         self.y=y
         return plt.plot (x,y,"om")

def oznaci(self):
    return plt.xlabel("x-os"), plt.ylabel("y-os"), plt.grid(b=True)

6 (slightly worse solution)

from numpy import*
M = array([[3,2,3],[1,2,6]])
class AriSred(object):
    def __init__(self,m):
    self.m=m
    
def srednja(self):
    redovi = len(M)
    stupci = len (M[0])
    lista=[]
    a=0
    suma=0
    while a<stupci:
        for i in range (0,redovi):
            suma=suma+ M[i,a]
        lista.append(suma)
        a=a+1
        suma=0
    b=array(lista) 
    b=b/redovi
    return b



OBJ = AriSred(M)
sr = OBJ.srednja()
