Is there some command to create this folder?

If smb face this issue again, you should know the most simple way to create .m2 folder.
If you unzipped maven and set up maven path variable - just try mvn clean command from anywhere you like!
Dont be afraid of error messages when running - it works and creates needed directory.

Let me add a little to Sebastian Roth's answer.

Your project can be compiled by using ndk-build in the command line after adding the code Sebastian had posted. But as for me, there were syntax errors in Eclipse, and I didn't have code completion.

Note that your project must be converted to a C/C++ project.

How to convert a C/C++ project

To fix this issue right-click on your project, click Properties

Choose C/C++ General -> Paths and Symbols and include the ${ANDROID_NDK}/sources/cxx-stl/stlport/stlport to Include directories

Click Yes when a dialog shows up.

The sizeof "trick" is the best way I know, with one small but (to me, this being a major pet peeve) important change in the use of parenthesis.

As the Wikipedia entry makes clear, C's sizeof is not a function; it's an operator. Thus, it does not require parenthesis around its argument, unless the argument is a type name. This is easy to remember, since it makes the argument look like a cast expression, which also uses parenthesis.

So: If you have the following:

int myArray[10];

You can find the number of elements with code like this:

size_t n = sizeof myArray / sizeof *myArray;

That, to me, reads a lot easier than the alternative with parenthesis. I also favor use of the asterisk in the right-hand part of the division, since it's more concise than indexing.

Of course, this is all compile-time too, so there's no need to worry about the division affecting the performance of the program. So use this form wherever you can.

It is always best to use sizeof on an actual object when you have one, rather than on a type, since then you don't need to worry about making an error and stating the wrong type.

For instance, say you have a function that outputs some data as a stream of bytes, for instance across a network. Let's call the function send(), and make it take as arguments a pointer to the object to send, and the number of bytes in the object. So, the prototype becomes:

void send(const void *object, size_t size);

And then you need to send an integer, so you code it up like this:

int foo = 4711;
send(&foo, sizeof (int));

Now, you've introduced a subtle way of shooting yourself in the foot, by specifying the type of foo in two places. If one changes but the other doesn't, the code breaks. Thus, always do it like this:

send(&foo, sizeof foo);

Now you're protected. Sure, you duplicate the name of the variable, but that has a high probability of breaking in a way the compiler can detect, if you change it.

In MySQL

In SQL Server

where datetime_column > dateadd(m, -6, getdate() - datepart(d, getdate()) + 1)

You can pass "<>" (including the quotes) as the parameter for criteria. This basically says, as long as its not empty/blank, count it. I believe this is what you want.

=COUNTIF(A1:A10, "<>") 

Otherwise you can use CountA as Scott suggests

These solutions totally make sense. Unfortunately, neither worked for me as expected. Instead of trying to hassle with it, I went with a work around:

select * from information_schema.columns 
where replace(table_name,'_','!') not like '%!%'
order by table_name

I'm still getting my feet wet with Node.js, but I have a few ideas. first, I believe you need to use execFile instead of spawn; execFile is for when you have the path to a script, whereas spawn is for executing a well-known command that Node.js can resolve against your system path.

1. Provide a callback to process the buffered output:

var child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3', 
], function(err, stdout, stderr) { 
    // Node.js will invoke this callback when process terminates.
    console.log(stdout); 
});  

2. Add a listener to the child process' stdout stream (9thport.net)

var child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3' ]); 
// use event hooks to provide a callback to execute when data are available: 
child.stdout.on('data', function(data) {
    console.log(data.toString()); 
});

Further, there appear to be options whereby you can detach the spawned process from Node's controlling terminal, which would allow it to run asynchronously. I haven't tested this yet, but there are examples in the API docs that go something like this:

child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3', 
], { 
    // detachment and ignored stdin are the key here: 
    detached: true, 
    stdio: [ 'ignore', 1, 2 ]
}); 
// and unref() somehow disentangles the child's event loop from the parent's: 
child.unref(); 
child.stdout.on('data', function(data) {
    console.log(data.toString()); 
});

The this Keyword is used to refer the current variable of a block, for example consider the below code(Just a exampple, so dont expect the standard JAVA Code):

Public class test{

test(int a) {
this.a=a;
}

Void print(){
System.out.println(a);
}

   Public static void main(String args[]){
    test s=new test(2);
    s.print();
 }
}

Thats it. the Output will be "2". If We not used the this keyword, then the output will be : 0

As from Android developer guide :

"orientation" The screen orientation has changed — the user has rotated the device. Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.

"screenSize" The current available screen size has changed. This represents a change in the currently available size, relative to the current aspect ratio, so will change when the user switches between landscape and portrait. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device). Added in API level 13.

So, in the AndroidManifest.xml file, we can put:

<activity
            android:name=".activities.role_activity.GeneralViewPagerActivity"
            android:label="@string/title_activity_general_view_pager"
            android:screenOrientation="portrait"
            android:configChanges="orientation|keyboardHidden|screenSize"
            >
        </activity> 

You can use memset with the size of the struct:

struct x x_instance;
memset (&x_instance, 0, sizeof(x_instance));

Here is a working example (you'll have to trust me that there's a submit() method on the controller - it prints an Object, like {user: 'abc'} if 'abc' is entered in the input field):

<form #loginForm="ngForm" (ngSubmit)="submit(loginForm.value)">
    <input type="text" name="user" ngModel required>
    <button  type="submit"  [disabled]="loginForm.invalid">
        Submit
    </button>
</form>

As you can see:

• don't use loginForm.form, just use loginForm
• loginForm.invalid works as well as !loginForm.valid
• if you want submit() to be passed the correct value(s), the input element should have name and ngModel attributes

Also, this is when you're NOT using the new FormBuilder, which I recommend. Things are very different when using FormBuilder.

If I have open a package in BIDS ("Business Intelligence Development Studio", the tool you use to design the packages), and do not select any item in it, I have a "Properties" pane in the bottom right containing - among others, the MaximumErrorCount property. If you do not see it, maybe it is minimized and you have to open it (have a look at tabs in the right).

If you cannot find it this way, try the menu: View/Properties Window.

Or try the F4 key.

For auto-completion triggers in Eclipse like IntelliJ, follow these steps,

1. Go to the Eclipse Windows menu -> Preferences -> Java -> Editor -> Content assist and check your settings here
2. Enter in Autocomplete activation string for java: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._@
3. Apply and Close the Dialog box.

Thanks.

On my 2012 MacBook Air (Intel Core i5-3427U, 2x 1.8 GHz, 2.8 GHz Turbo), SHA-1 is slightly faster than MD5 (using OpenSSL in 64-bit mode):

Here's the solution I use. I can't remember why I couldn't just use the PictureBox.Load methods. I'm pretty sure it's because I wanted to properly scale & center the downloaded image into the PictureBox control. If I recall, all the scaling options on PictureBox either stretch the image, or will resize the PictureBox to fit the image. I wanted a properly scaled and centered image in the size I set for PictureBox.

Now, I just need to make a async version...

Here's my methods:

Here's the required includes. (Some might be needed by other code, but including all to be safe)

How I generally use it:

for this problem please follow bellow code:

$time= '10:09';
$new_time=date('H:i',strtotime($time.'+ 1 hour'));

Well, as everyone said, use -S option. If you use -save-temps option, you can also get preprocessed file(.i), assembly file(.s) and object file(*.o). (get each of them by using -E, -S, and -c.)

I find it strange that nobody mentioned that all of the methods listed above creates a cycle reference between the added method and the instance, causing the object to be persistent till garbage collection. There was an old trick adding a descriptor by extending the class of the object:

def addmethod(obj, name, func):
    klass = obj.__class__
    subclass = type(klass.__name__, (klass,), {})
    setattr(subclass, name, func)
    obj.__class__ = subclass

I/O Bound process:- If most part of the lifetime of a process is spent in i/o state, then the process is a i/o bound process.example:-calculator,internet explorer

CPU Bound process:- If most part of the process life is spent in cpu,then it is cpu bound process.

Ctrl+C terminates the main thread, but because your threads aren't in daemon mode, they keep running, and that keeps the process alive. We can make them daemons:

f = FirstThread()
f.daemon = True
f.start()
s = SecondThread()
s.daemon = True
s.start()

But then there's another problem - once the main thread has started your threads, there's nothing else for it to do. So it exits, and the threads are destroyed instantly. So let's keep the main thread alive:

import time
while True:
    time.sleep(1)

Now it will keep print 'first' and 'second' until you hit Ctrl+C.

Edit: as commenters have pointed out, the daemon threads may not get a chance to clean up things like temporary files. If you need that, then catch the KeyboardInterrupt on the main thread and have it co-ordinate cleanup and shutdown. But in many cases, letting daemon threads die suddenly is probably good enough.

I got this error writing a Jasmine unit test. I had the line:

It needed to be:

angular.injector(['ng', 'myModule'])

Another option would be file_get_contents():

// $xml_str = your xml
// $url = target url

$post_data = array('xml' => $xml_str);
$stream_options = array(
    'http' => array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded' . "\r\n",
        'content' =>  http_build_query($post_data)));

$context  = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);

your event is triggered only once... so this code may work try this

    $(".addproduct,.addproduct,.addproduct,.addproduct,.addproduct").click(function(){//do     something fired 5 times});

You have to put the entire path as a parameter to os.path.split. See The docs. It doesn't work like string split.

Can't you just create a static method that does exactly this?

private static <K, V> V getOrDefault(Map<K,V> map, K key, V defaultValue) {
    return map.containsKey(key) ? map.get(key) : defaultValue;
}

You have two choices:

1. Use fileno() to obtain the file descriptor associated with the stdio stream pointer

2. Don't use <stdio.h> at all, that way you don't need to worry about flush either - all writes will go to the device immediately, and for character devices the write() call won't even return until the lower-level IO has completed (in theory).

For device-level IO I'd say it's pretty unusual to use stdio. I'd strongly recommend using the lower-level open(), read() and write() functions instead (based on your later reply):

int fd = open("/dev/i2c", O_RDWR);
ioctl(fd, IOCTL_COMMAND, args);
write(fd, buf, length);

Here is a dplyr/tidyverse solution using the na_if() function:

dat %>% mutate_if(is.numeric, list(~na_if(., Inf)))

Note that this only replaces positive infinity with NA. Need to repeat if negative infinity values also need to be replaced.

dat %>% mutate_if(is.numeric, list(~na_if(., Inf))) %>% 
  mutate_if(is.numeric, list(~na_if(., -Inf)))

Minor update on top of Karthik Bose's answer - you can configure git globally, to affect all of your workspaces to behave that way:

git config --global push.default upstream

You may also want to try two backslashes (\\") to escape the escape character.

var matches = [];
$(".className:checked").each(function() {
    matches.push(this.value);
});

None of these solutions worked for me. I had to append bash environment to the zsh:

echo 'source ~/.bash_profile' >> ~/.zshrc

HTTP authorization does not differ between GET and POST requests, so I would first assume that something else is wrong. Instead of setting the Authorization header directly, I would suggest using the java.net.Authorization class, but I am not sure if it solves your problem. Perhaps your server is somehow configured to require a different authorization scheme than "basic" for post requests?

I found the answer that worked for me here: http://txt.arboreus.com/2012/07/11/highgui-opencv-window-from-ipython.html

If you run an interactive ipython session, and want to use highgui windows, do cv2.startWindowThread() first.

In detail: HighGUI is a simplified interface to display images and video from OpenCV code. It should be as easy as:

import cv2
img = cv2.imread("image.jpg")
cv2.startWindowThread()
cv2.namedWindow("preview")
cv2.imshow("preview", img)

Forget browser and try CLI. HTTPie is great tool!

CLI http clients:

• HTTPie
• HTTP Prompt
• Curl
• wget

If you insist on browser extension then:

Chrome:

• Postman - REST Client (deprecated, now has a desktop program)
• Advanced REST client
• Talend API Tester - Free Edition

Firefox:

• RESTClient

Your error is also shown when trying to access the sizeof() of an non-initialized extern array:

extern int a[];
sizeof(a);
>> error: invalid application of 'sizeof' to incomplete type 'int[]'

Note that you would get an array size missing error without the extern keyword.

You can force the currently-editing view to resign its first responder status with [view endEditing:YES]. This hides the keyboard.

Unlike -[UIResponder resignFirstResponder], -[UIView endEditing:] will search through subviews to find the current first responder. So you can send it to your top-level view (e.g. self.view in a UIViewController) and it will do the right thing.

(This answer previously included a couple of other solutions, which also worked but were more complicated than is necessary. I've removed them to avoid confusion.)

Just another case here. I had this error from Managed Debugging Assistant on the first time deserializing a XML file into objects under VS2010/.NET 4. A DLL containing classes for the objects is generated in a post-build event (usual Microsoft style stuff). Worked very well for several projects in same solution, problem appeared when doing that in one more of the projects. Error text:

BindingFailure was detected Message: The assembly with display name MyProjectName.XmlSerializers' failed to load in the 'LoadFrom' binding context of the AppDomain with ID 1. The cause of the failure was: System.IO.FileLoadException: Could not load file or assembly MyProjectName.XmlSerializers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Since some answers here suggested a platform mismatch, I noticed that 3 projects and the solution had "mixed platforms" configuration selected, and 3 projects were compiled for x86 instead of AnyCPU. I have no platform-specific code (though some vendor-provided DLLs rely on a few x86 libraries). I replaced all occurrences of x86 into AnyCPU with this:

for a in $( egrep '(x86|AnyCPU)' */*.csproj *.sln -l  ) ; do echo $a ; sed -i 's/x86/AnyCPU/' $a ; done

Then the project would build but all options to run or debug code would be greyed out. Restarting VS would not help.

I reverted with git the references to the x86-library, just in case, but kept AnyCPU for all the code I compile.

Following F5 or Start Debugging Button is Greyed Out for Winform application? I unloaded and reloaded the starting project (it was also the one where the initial problem appeared in the first place).

After that, everything fell back into place: the program works without the initial error.

solution

M-: (load user-init-file)

notes

• you type it in Eval: prompt (including the parentheses)
• user-init-file is a variable holding the ~/.emacs value (pointing to the configuration file path) by default
• (load) is shorter, older, and non-interactive version of (load-file); it is not an emacs command (to be typed in M-x) but a mere elisp function

conclusion

M-: > M-x

I started by using the answers here, but modified it to use YouTube's new iframe embedding...

$('a.more').on('click', function(event) {
    event.preventDefault();
    $.fancybox({
        'type' : 'iframe',
        // hide the related video suggestions and autoplay the video
        'href' : this.href.replace(new RegExp('watch\\?v=', 'i'), 'embed/') + '?rel=0&autoplay=1',
        'overlayShow' : true,
        'centerOnScroll' : true,
        'speedIn' : 100,
        'speedOut' : 50,
        'width' : 640,
        'height' : 480
    });
});

First include the file in head tag of html , then call the function in script tags under body tags e.g.

Js file function to be called

function tryMe(arg) {
    document.write(arg);
}

HTML FILE

<!DOCTYPE html>
<html>
<head>
    <script type="text/javascript" src='object.js'> </script>
    <title>abc</title><meta charset="utf-8"/>
</head>
<body>
    <script>
    tryMe('This is me vishal bhasin signing in');
    </script>
</body>
</html>

finish

Just use vanilla JS. You can use splice to remove the element:

obj.subTopics.splice(1, 1);

Demo

1. open the Build Variants pane, typically found along the lower left side of the window:

2. set debug to release
3. shift+f10 run!!

then, Android Studio will execute assembleRelease task and install xx-release.apk to your device.

Simply use

$(document).height() // - $('body').offset().top

and / or

$(window).height()

instead of $('body').height();

I am using this interceptors to get the error response.

const HttpClient = axios.create({
  baseURL: env.baseUrl,
});

HttpClient.interceptors.response.use((response) => {
  return response;
}, (error) => {
  return Promise.resolve({ error });
});

For everyone struggling with this issue, you simply need to upgrade your openssl installation. I'm running windows 10, installed the latest anaconda 64-bit and am getting this error when I try to install/upgrade anything with 'conda' or 'pip'. If I uninstall the 64-bit anaconda and install the 32-bit, it works fine. I had a 64-bit version of openssl for windows installed, version 1.1.0 something. I uninstalled that and installed the latest I could find from here: https://slproweb.com/products/Win32OpenSSL.html -- there is a 64-bit version of 1.1.1 on there that worked. Now I can install packages via pip and conda successfully. Hope this helps.

React.createClass method has been deprecated in the new version of React, you can do it very simply in the following way make one functional component and another class component to maintain state:

Parent:

const ParentComp = () => {_x000D_
  _x000D_
  getLanguage = (language) => {_x000D_
    console.log('Language in Parent Component: ', language);_x000D_
  }_x000D_
  _x000D_
  <ChildComp onGetLanguage={getLanguage}_x000D_
};

Child:

class ChildComp extends React.Component {_x000D_
    state = {_x000D_
      selectedLanguage: ''_x000D_
    }_x000D_
    _x000D_
    handleLangChange = e => {_x000D_
        const language = e.target.value;_x000D_
        thi.setState({_x000D_
          selectedLanguage = language;_x000D_
        });_x000D_
        this.props.onGetLanguage({language}); _x000D_
    }_x000D_
_x000D_
    render() {_x000D_
        const json = require("json!../languages.json");_x000D_
        const jsonArray = json.languages;_x000D_
        const selectedLanguage = this.state;_x000D_
        return (_x000D_
            <div >_x000D_
                <DropdownList ref='dropdown'_x000D_
                    data={jsonArray} _x000D_
                    value={tselectedLanguage}_x000D_
                    caseSensitive={false} _x000D_
                    minLength={3}_x000D_
                    filter='contains'_x000D_
                    onChange={this.handleLangChange} />_x000D_
            </div>            _x000D_
        );_x000D_
    }_x000D_
};

I was looking to do exactly the same thing (RESTful web service), and I stumbled upon this firefox addon, which lets you modify the accept headers (actually, any request headers) for requests. It works perfectly.

https://addons.mozilla.org/en-US/firefox/addon/967/

if you use recompose, use mapProps to make new props derived from incoming props

Edit for example:

import { compose, mapProps } from 'recompose';

const SomeComponent = ({ url, onComplete }) => (
  {url ? (
    <View />
  ) : null}
)

export default compose(
  mapProps(({ url, storeUrl, history, ...props }) => ({
    ...props,
    onClose: () => {
      history.goBack();
    },
    url: url || storeUrl,
  })),
)(SomeComponent);

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

L is a prefix used for wide strings. Each character uses several bytes (depending on the size of wchar_t). The encoding used is independent from this prefix. I mean it must not be necessarily UTF-16 unlike stated in other answers here.

If you're getting an error because one of your variables contains a value that contains white spaces you can try to reset bash's IFS (Internal Field Separator) to \n to let bash interpret cat .env result as a list of parameters for the env executable.

Example:

IFS=$'\n'; env $(cat .env) rails c

I got this error when I had an invalid Type for an entity property.

public Type ObjectType {get;set;}

When I removed the property the error stopped occurring.

In my case, I needed to copy the google-play-services_lib FOLDER in the same DRIVE of the source codes of my apps

• F:\Products\Android\libs\google-play-services_lib

Summary:

In ES6/ES 2015 the class keyword was introduced with an accompanied static keyword. Keep in mind that this is syntactic sugar over the prototypal inheritance model which javavscript embodies. The static keyword works in the following way for methods:

class Dog {_x000D_
_x000D_
  static bark () {console.log('woof');}_x000D_
  // classes are function objects under the hood_x000D_
  // bark method is located on the Dog function object_x000D_
  _x000D_
  makeSound () { console.log('bark'); }_x000D_
  // makeSound is located on the Dog.prototype object_x000D_
_x000D_
}_x000D_
_x000D_
// to create static variables just create a property on the prototype of the class_x000D_
Dog.prototype.breed = 'Pitbull';_x000D_
// So to define a static property we don't need the `static` keyword._x000D_
_x000D_
const fluffy = new Dog();_x000D_
const vicky = new Dog();_x000D_
console.log(fluffy.breed, vicky.breed);_x000D_
_x000D_
// changing the static variable changes it on all the objects_x000D_
Dog.prototype.breed = 'Terrier';_x000D_
console.log(fluffy.breed, vicky.breed);

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

This question is very, very, very old, but as a trick in the future, I recommend something like this:

.element{
    box-shadow: 0px 0px 10px #232931;
}
.container{
    height: 100px;
    width: 100px;
    overflow: hidden;
}

Basically, you have a box shadow and then wrapping the element in a div with its overflow set to hidden. You'll need to adjust the height, width, and even padding of the div to only show the left box shadow, but it works. See here for an example If you look at the example, you can see how there's no other shadows, but only a black left shadow. Edit: this is a retake of the same screen shot, in case some one thinks that I just cropped out the right. You can find it here

Smalltalk:

Have a class method in a class Test, that returns a constant string:

method1
    ^ 'niko'

You should expect that this method constantly returns the string 'niko' whatever happens. But that is not the case.

s := Test method1 

(Set s to 'niko'.)

s at: 4 put: $i.

(Set s to 'niki'.)

s := Test method1

(Set s to 'niki' again.)

So, what happens is that the second line of code permanently changed method1 to return 'niki' rather than 'niko', even though the source code of the method was not updated.

You can use re.escape():

re.escape(string) Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

>>> import re
>>> re.escape('^a.*$')
'\\^a\\.\\*\\$'

If you are using a Python version < 3.7, this will escape non-alphanumerics that are not part of regular expression syntax as well.

If you are using a Python version < 3.7 but >= 3.3, this will escape non-alphanumerics that are not part of regular expression syntax, except for specifically underscore (_).

try this for close app

Activity.finish();
System.exit(0);

No one has mentioned that

In default settings, Floats (System.Single) and doubles (System.Double) will never use overflow checking while Decimal (System.Decimal) will always use overflow checking.

I mean

decimal myNumber = decimal.MaxValue;
myNumber += 1;

throws OverflowException.

But these do not:

float myNumber = float.MaxValue;
myNumber += 1;

&

double myNumber = double.MaxValue;
myNumber += 1;

Solution for Pressing or handling back button in Fragment.

The way I solved my issue I am sure it will helps you too:

1.If you don't have any Edit Text-box in your fragment you can use below code

Here MainHomeFragment is main Fragment (When I press back button from second fragment it will take me too MainHomeFragment)

    @Override
    public void onResume() {

    super.onResume();

    getView().setFocusableInTouchMode(true);
    getView().requestFocus();
    getView().setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){

                MainHomeFragment mainHomeFragment = new SupplierHomeFragment();
                android.support.v4.app.FragmentTransaction fragmentTransaction =
                        getActivity().getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.fragment_container, mainHomeFragment);
                fragmentTransaction.commit();

                return true;    
            }    
            return false;
        }
    }); }

2.If you have another fragment named as Somefragment and it has Edit text-box then you can do it by this way.

private EditText editText;

Then In,

onCreateView():    
editText = (EditText) view.findViewById(R.id.editText);

Then Override OnResume,

@Override
public void onResume() {
    super.onResume();

    editText.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                editTextOFS.clearFocus();
                getView().requestFocus();
            }
            return false;
        }
    });

    getView().setFocusableInTouchMode(true);
    getView().requestFocus();
    getView().setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){

                MainHomeFragment mainHomeFragment = new SupplierHomeFragment();
                android.support.v4.app.FragmentTransaction fragmentTransaction =
                        getActivity().getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.fragment_container, mainHomeFragment);
                fragmentTransaction.commit();

                return true;

            }

            return false;
        }
    });

}

That's all folks (amitamie.com) :-) ;-)

You can use getActivity() method to get context or You can use getContext() method .

 View root = inflater.inflate(R.layout.fragment_slideshow, container, false);
    Context c = root.getContext();

I hope it helps!

Since it wasn't mentioned in the other answers, I'd like to add that if you want case SearchAuthors to be executed right after the first case, just like omitting the break in some other programming languages where that is allowed, you can simply use goto.

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

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

SO thread 'Multiply two arrays element wise, where one of the arrays has arrays as elements' has an example of constructing an array from arrays. If the subarrays are the same size, numpy makes a 2d array. But if they differ in length, it makes an array with dtype=object, and the subarrays retain their identity.

Following that, you could do something like this:

In [5]: result=np.array([np.zeros((1)),np.zeros((2))])

In [6]: result
Out[6]: array([array([ 0.]), array([ 0.,  0.])], dtype=object)

In [7]: np.append([result[0]],[1,2])
Out[7]: array([ 0.,  1.,  2.])

In [8]: result[0]
Out[8]: array([ 0.])

In [9]: result[0]=np.append([result[0]],[1,2])

In [10]: result
Out[10]: array([array([ 0.,  1.,  2.]), array([ 0.,  0.])], dtype=object)

However, I don't offhand see what advantages this has over a pure Python list or lists. It does not work like a 2d array. For example I have to use result[0][1], not result[0,1]. If the subarrays are all the same length, I have to use np.array(result.tolist()) to produce a 2d array.

Go to Settings->Basic, on top you will find a Switch button which will say App is in development mode.

Click on in development switch button, it will ask you to make app live, and after providing all necessary things, it will become live.

You also might want to check if the file already exists to avoid replacing the file by accident (unless that is the idea of course:

Dim filepath as String = "C:\my files\2010\SomeFileName.txt"
If Not System.IO.File.Exists(filepath) Then
   System.IO.File.Create(filepath).Dispose()
End If

For JPA fixed using EntityManager merge() instead of persist()

EntityManager em = getEntityManager();
    try {
        em.getTransaction().begin();
        em.merge(fieldValue);
        em.getTransaction().commit();
    } catch (Exception e) {
        //do smthng
    } finally {
        em.close();
    }

Renderer has been deprecated in Angular 4.0.0-rc.1, read the update below

The angular2 way is to use listen or listenGlobal from Renderer

For example, if you want to add a click event to a Component, you have to use Renderer and ElementRef (this gives you as well the option to use ViewChild, or anything that retrieves the nativeElement)

constructor(elementRef: ElementRef, renderer: Renderer) {

    // Listen to click events in the component
    renderer.listen(elementRef.nativeElement, 'click', (event) => {
      // Do something with 'event'
    })
);

You can use listenGlobal that will give you access to document, body, etc.

renderer.listenGlobal('document', 'click', (event) => {
  // Do something with 'event'
});

Note that since beta.2 both listen and listenGlobal return a function to remove the listener (see breaking changes section from changelog for beta.2). This is to avoid memory leaks in big applications (see #6686).

So to remove the listener we added dynamically we must assign listen or listenGlobal to a variable that will hold the function returned, and then we execute it.

// listenFunc will hold the function returned by "renderer.listen"
listenFunc: Function;

// globalListenFunc will hold the function returned by "renderer.listenGlobal"
globalListenFunc: Function;

constructor(elementRef: ElementRef, renderer: Renderer) {
    
    // We cache the function "listen" returns
    this.listenFunc = renderer.listen(elementRef.nativeElement, 'click', (event) => {
        // Do something with 'event'
    });

    // We cache the function "listenGlobal" returns
    this.globalListenFunc = renderer.listenGlobal('document', 'click', (event) => {
        // Do something with 'event'
    });
}

ngOnDestroy() {
    // We execute both functions to remove the respectives listeners

    // Removes "listen" listener
    this.listenFunc();
    
    // Removs "listenGlobal" listener
    this.globalListenFunc();
}

Here's a plnkr with an example working. The example contains the usage of listen and listenGlobal.

Using RendererV2 with Angular 4.0.0-rc.1+ ^{_{(Renderer2 since 4.0.0-rc.3)}}

• 25/02/2017: Renderer has been deprecated, now we should use RendererV2 (see line below). See the commit.

• 10/03/2017: RendererV2 was renamed to Renderer2. See the breaking changes.

RendererV2 has no more listenGlobal function for global events (document, body, window). It only has a listen function which achieves both functionalities.

For reference, I'm copy & pasting the source code of the DOM Renderer implementation since it may change (yes, it's angular!).

listen(target: 'window'|'document'|'body'|any, event: string, callback: (event: any) => boolean):
      () => void {
    if (typeof target === 'string') {
      return <() => void>this.eventManager.addGlobalEventListener(
          target, event, decoratePreventDefault(callback));
    }
    return <() => void>this.eventManager.addEventListener(
               target, event, decoratePreventDefault(callback)) as() => void;
  }

As you can see, now it verifies if we're passing a string (document, body or window), in which case it will use an internal addGlobalEventListener function. In any other case, when we pass an element (nativeElement) it will use a simple addEventListener

To remove the listener it's the same as it was with Renderer in angular 2.x. listen returns a function, then call that function.

Example

// Add listeners
let global = this.renderer.listen('document', 'click', (evt) => {
  console.log('Clicking the document', evt);
})

let simple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
  console.log('Clicking the button', evt);
});

// Remove listeners
global();
simple();

plnkr with Angular 4.0.0-rc.1 using RendererV2

plnkr with Angular 4.0.0-rc.3 using Renderer2

You can use like this:

case 4: case 2:
 {
   //code ...
 }

For use 4 or 2 switch case.

I think the best easy way in this case is to use parseToStringDate which is part of GDK (Groovy JDK enhancements):

Parse a String matching the pattern EEE MMM dd HH:mm:ss zzz yyyy containing US-locale-constants only (e.g. Sat for Saturdays). Such a string is generated by the toString method of Date

Example:

println(Date.parseToStringDate("Tue Aug 10 16:02:43 PST 2010").format('MM-dd-yyyy'))

to get the last row of a SQL-Database use this sql string:

SELECT * FROM TableName WHERE id=(SELECT max(id) FROM TableName);

Output:

Last Line of your db!

I got the same error in this code:

 var articulos_en_almacen = xx.IV00102.Where(iv => alm_x_suc.Exists(axs => axs.almacen == iv.LOCNCODE.Trim())).Select(iv => iv.ITEMNMBR.Trim()).ToList();

this was the exactly error:

System.NotSupportedException: 'LINQ to Entities does not recognize the method 'Boolean Exists(System.Predicate`1[conector_gp.Models.almacenes_por_sucursal])' method, and this method cannot be translated into a store expression.'

I solved this way:

var articulos_en_almacen = xx.IV00102.ToList().Where(iv => alm_x_suc.Exists(axs => axs.almacen == iv.LOCNCODE.Trim())).Select(iv => iv.ITEMNMBR.Trim()).ToList();

I added a .ToList() before my table, this decouple the Entity and linq code, and avoid my next linq expression be translated

NOTE: this solution isn't optimal, because avoid entity filtering, and simply loads all table into memory

Convert CString to string (VC6)

I have tested this and it works fine.

std::string Utils::CString2String(const CString& cString) 
{
    std::string strStd;

    for (int i = 0;  i < cString.GetLength();  ++i)
    {
        if (cString[i] <= 0x7f)
            strStd.append(1, static_cast<char>(cString[i]));
        else
            strStd.append(1, '?');
    }

    return strStd;
}

import requests

site_request = requests.get("https://abhiunix.in")

site_response = str(site_request.content)

print(site_response)

You can do it either way.

This always can happen in DataBinding. Try to stay away from adding logic in your bindings, including appending an empty string. You can make your own custom adapter, and use it multiple times.

@BindingAdapter("numericText")
fun numericText(textView: TextView, value: Number?) {
    value?.let {
        textView.text = value.toString()
    }
}

<TextView app:numericText="@{list.size()}" .../>

It is possible to use the host_name() function

select HOST_NAME()

As I understand it, roles were initially defined by XHTML but were deprecated. However, they are now defined by HTML 5, see here: https://www.w3.org/WAI/PF/aria/roles#abstract_roles_header

The purpose of the role attribute is to identify to parsing software the exact function of an element (and its children) as part of a web application. This is mostly as an accessibility thing for screen readers, but I can also see it as being useful for embedded browsers and screen scrapers. In order to be useful to the unusual HTML client, the attribute needs to be set to one of the roles from the spec I linked. If you make up your own, this 'future' functionality can't work - a comment would be better.

Practicalities here: http://www.accessibleculture.org/articles/2011/04/html5-aria-2011/

In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.

  def change
    change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13
    change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13
  end

A class can only "implement" an interface. A class only "extends" a class. Likewise, an interface can extend another interface.

A class can only extend one other class. A class can implement several interfaces.

If instead you are more interested in knowing when to use abstract classes and interfaces, refer to this thread: Interface vs Abstract Class (general OO)

I believe buffer length needs to be specified, as memory is finite and you may run out of it

Example:

InputStream in = new FileInputStream(strFileName);
    long length = fileFileName.length();

    if (length > Integer.MAX_VALUE) {
        throw new IOException("File is too large!");
    }

    byte[] bytes = new byte[(int) length];

    int offset = 0;
    int numRead = 0;

    while (offset < bytes.length && (numRead = in.read(bytes, offset, bytes.length - offset)) >= 0) {
        offset += numRead;
    }

    if (offset < bytes.length) {
        throw new IOException("Could not completely read file " + fileFileName.getName());
    }

    in.close();

We here use simply linear search. At first initialize the index equal to -1 . Then search the array , if found the assign the index value in index variable and break. Otherwise, index = -1.

   int find(int arr[], int n, int key)
   {
     int index = -1;

       for(int i=0; i<n; i++)
       {
          if(arr[i]==key)
          {
            index=i;
            break;
          }
       }
      return index;
    }


 int main()
 {
    int arr[ 5 ] = { 4, 1, 3, 2, 6 };
    int n =  sizeof(arr)/sizeof(arr[0]);
    int x = find(arr ,n, 3);
    cout<<x<<endl;
    return 0;
 }

From MDN by setAttribute():

To set the value of a Boolean attribute, such as disabled, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true. The absence of the attribute means its value is false. By setting the value of the disabled attribute to the empty string (""), we are setting disabled to true, which results in the button being disabled.

Link to MDN

Solution

• I mean that in XHTML Strict is right disabled="disabled",
• and in HTML5 is only disabled, like <input name="myinput" disabled>
• In javascript, I set the value to true via e.disabled = true;
  or to "" via setAttribute( "disabled", "" );

Test in Chrome

var f = document.querySelectorAll( "label.disabled input" );
for( var i = 0; i < f.length; i++ )
{
    // Reference
    var e = f[ i ];

    // Actions
    e.setAttribute( "disabled", false|null|undefined|""|0|"disabled" );
    /*
        <input disabled="false"|"null"|"undefined"|empty|"0"|"disabled">
        e.getAttribute( "disabled" ) === "false"|"null"|"undefined"|""|"0"|"disabled"
        e.disabled === true
    */
    
    e.removeAttribute( "disabled" );
    /*
        <input>
        e.getAttribute( "disabled" ) === null
        e.disabled === false
    */

    e.disabled = false|null|undefined|""|0;
    /*
        <input>
        e.getAttribute( "disabled" ) === null|null|null|null|null
        e.disabled === false
    */

    e.disabled = true|" "|"disabled"|1;
    /*
        <input disabled>
        e.getAttribute( "disabled" ) === ""|""|""|""
        e.disabled === true
    */
}

Add below lines to your project

if __name__ == '__main__':
    app.debug = True
    app.run(host = '0.0.0.0',port=5005)

Here is a bare bones version:

Let's say that you have a date in Cell A1 in the format you described. For example: 19760210.

Then this formula will give you the date you want:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2)).

On my system (Excel 2010) it works with strings or floats.

The <textarea> element automatically aligns text at the top of a textbox, if you don't want to use CSS to force it.

You could simply replace the separator characters by NULL characters, and store the address after the newly created NULL character in a new char* pointer:

char* input = "asdf|qwer"
char* parts[10];
int partcount = 0;

parts[partcount++] = input;

char* ptr = input;
while(*ptr) { //check if the string is over
    if(*ptr == '|') {
        *ptr = 0;
        parts[partcount++] = ptr + 1;
    }
    ptr++;
}

Note that this code will of course not work if the input string contains more than 9 separator characters.

DO NOT use this:

System.Environment.GetEnvironmentVariable("TEMP")

Environment variables can be overridden, so the TEMP variable is not necessarily the directory.

The correct way is to use System.IO.Path.GetTempPath() as in the accepted answer.

Apart from fixing the imports, do a fresh maven clean compile -U. Note the -U option, that brings in new dependencies which sometimes the editor has hard time with. Let the compilation fail due to un-imported classes, but at least you have an option to import them after the maven command.

Just doing Maven->Reimport from Intellij did not work for me.

The intent of the standalone=yes declaration is to guarantee that the information inside the document can be faithfully retrieved based only on the internal DTD, i.e. the document can "stand alone" with no external references. Validating a standalone document ensures that non-validating processors will have all of the information available to correctly parse the document.

The standalone declaration serves no purpose if a document has no external DTD, and the internal DTD has no parameter entity references, as these documents are already implicitly standalone.

The following are the actual effects of using standalone=yes.

• Forces processors to throw an error when parsing documents with an external DTD or parameter entity references, if the document contains references to entities not declared in the internal DTD (with the exception of replacement text of parameter entities as non-validating processors are not required to parse this); amp, lt, gt, apos, and quot are the only exceptions

• When parsing a document not declared as standalone, a non-validating processor is free to stop parsing the internal DTD as soon as it encounters a parameter entity reference. Declaring a document as standalone forces non-validating processors to parse markup declarations in the internal DTD even after they ignore one or more parameter entity references.

• Forces validating processors to throw an error if any of the following are found in the document, and their respective declarations are in the external DTD or in parameter entity replacement text:

  • attributes with default values, if they do not have their value explicitly provided
  • entity references (other than amp, lt, gt, apos, and quot)
  • attributes with tokenized types, if the value of the attribute would be modified by normalization
  • elements with element content, if any white space occurs in their content

A non-validating processor might consider retrieving the external DTD and expanding all parameter entity references for documents that are not standalone, even though it is under no obligation to do so, i.e. setting standalone=yes could theoretically improve performance for non-validating processors (spoiler alert: it probably won't make a difference).

The other answers here are either incomplete or incorrect, the main misconception is that

The standalone declaration is a way of telling the parser to ignore any markup declarations in the DTD. The DTD is thereafter used for validation only.

standalone="yes" means that the XML processor must use the DTD for validation only.

Quite the opposite, declaring a document as standalone will actually force a non-validating processor to parse internal declarations it must normally ignore (i.e. those after an ignored parameter entity reference). Non-validating processors must still use the info in the internal DTD to provide default attribute values and normalize tokenized attributes, as this is independent of validation.

To those who are stuck wondering why a window flashes and goes away without doing anything, the problem may related to the RELATIVE path in your Python script. e.g. you used ".\". Even the Python script and Excel Workbook is in the same directory, the Current Directory may still be different. If you don't want to modify your code to change it to an absolute path. Just change your current Excel directory before you run the python script by:

ChDir ActiveWorkbook.Path

I'm just giving a example here. If the flash do appear, one of the first issues to check is the Current Working Directory.

When using the .html() method, a htmlString must be the parameter. (source) Put your string inside a HTML tag and it should work or use .text() as suggested by farzad.

Example:

<div class="demo-container">
    <div class="demo-box">Demonstration Box</div>
</div>

<script type="text/javascript">
$("div.demo-container").html( "<p>All new content. <em>You bet!</em></p>" );
</script>

How about this?

from operator import mul as MULTIPLY

def factors(n):
    f = {} # a dict is necessary to create 'factor : exponent' pairs 
    divisor = 2
    while n > 1:
        while (divisor <= n):
            if n % divisor == 0:
                n /= divisor
                f[divisor] = f.get(divisor, 0) + 1
            else:
                divisor += 1
    return f


def mcm(numbers):
    #numbers is a list of numbers so not restricted to two items
    high_factors = {}
    for n in numbers:
        fn = factors(n)
        for (key, value) in fn.iteritems():
            if high_factors.get(key, 0) < value: # if fact not in dict or < val
                high_factors[key] = value
    return reduce (MULTIPLY, ((k ** v) for k, v in high_factors.items()))

Use %systemdrive%%homepath%. %systemdrive% gives drive character ( Mostly C: ) and %homepath% gives user home directory ( \Users\<USERNAME> ).

For picking just one element of a generator use break in a for statement, or list(itertools.islice(gen, 1))

According to your example (literally) you can do something like:

while True:
  ...
  if something:
      for my_element in myfunct():
          dostuff(my_element)
          break
      else:
          do_generator_empty()

If you want "get just one element from the [once generated] generator whenever I like" (I suppose 50% thats the original intention, and the most common intention) then:

gen = myfunct()
while True:
  ...
  if something:
      for my_element in gen:
          dostuff(my_element)
          break
      else:
          do_generator_empty()

This way explicit use of generator.next() can be avoided, and end-of-input handling doesn't require (cryptic) StopIteration exception handling or extra default value comparisons.

The else: of for statement section is only needed if you want do something special in case of end-of-generator.

Note on next() / .next():

In Python3 the .next() method was renamed to .__next__() for good reason: its considered low-level (PEP 3114). Before Python 2.6 the builtin function next() did not exist. And it was even discussed to move next() to the operator module (which would have been wise), because of its rare need and questionable inflation of builtin names.

Using next() without default is still very low-level practice - throwing the cryptic StopIteration like a bolt out of the blue in normal application code openly. And using next() with default sentinel - which best should be the only option for a next() directly in builtins - is limited and often gives reason to odd non-pythonic logic/readablity.

Bottom line: Using next() should be very rare - like using functions of operator module. Using for x in iterator , islice, list(iterator) and other functions accepting an iterator seamlessly is the natural way of using iterators on application level - and quite always possible. next() is low-level, an extra concept, unobvious - as the question of this thread shows. While e.g. using break in for is conventional.

I prefer the base name which is already answered by fge. Another way is :

ls /home/user/new/*.txt|awk -F"/" '{print $NF}'

one more ugly way is :

ls /home/user/new/*.txt| perl -pe 's/\//\n/g'|tail -1

Field.CurrentPage only works for Filter fields (also called page fields).
If you want to filter a row/column field, you have to cycle through the individual items, like so:

Sub FilterPivotField(Field As PivotField, Value)
    Application.ScreenUpdating = False
    With Field
        If .Orientation = xlPageField Then
            .CurrentPage = Value
        ElseIf .Orientation = xlRowField Or .Orientation = xlColumnField Then
            Dim i As Long
            On Error Resume Next ' Needed to avoid getting errors when manipulating PivotItems that were deleted from the data source.
            ' Set first item to Visible to avoid getting no visible items while working
            .PivotItems(1).Visible = True
            For i = 2 To Field.PivotItems.Count
                If .PivotItems(i).Name = Value Then _
                    .PivotItems(i).Visible = True Else _
                    .PivotItems(i).Visible = False
            Next i
            If .PivotItems(1).Name = Value Then _
                .PivotItems(1).Visible = True Else _
                .PivotItems(1).Visible = False
        End If
    End With
    Application.ScreenUpdating = True
End Sub

Then, you would just call:

FilterPivotField ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode"), "K123223"

Naturally, this gets slower the more there are individual different items in the field. You can also use SourceName instead of Name if that suits your needs better.

This is a very interesting bug. (In my opinion, it is a bug anyway) Nice find!

Regarding how to set it, I would recommend Camilo Martin's answer. But as to why, I'd like to explain this a bit if you guys don't mind.

In the CSS specs I found:

'padding'
Percentages: refer to width of containing block

… which is weird, but okay.

So, with a parent width: 210px and a child padding-top: 50%, I get a calculated/computed value of padding-top: 96.5px – which is not the expected 105px.

That is because in Windows (I'm not sure about other OSs), the size of common scrollbars is per default 17px × 100% (or 100% × 17px for horizontal bars). Those 17px are substracted before calculating the 50%, hence 50% of 193px = 96.5px.

Check if your website on IIS is not stop.

I fixed it put my web site to run. :D

In case you also want to include your real name in the from-field, you can use the following format

mailx -r "[email protected] (My Name)" -s "My Subject" ...

If you happen to have non-ASCII characters in you name, like My AEÆoeøaaå (Æ= C3 86, ø= C3 B8, å= C3 A5), you have to encode them like this:

mailx -r "[email protected] (My =?utf-8?Q?AE=C3=86oe=C3=B8aa=C3=A5?=)" -s "My Subject" ...

Hope this can save someone an hour of hard work/research!

The Ctrl + F5 solusion didn't work for me in Chrome.

But I found How to Clear Chrome Cache for Specific Website Only (3 Steps):

1. As the page is loaded, open Chrome Developer Tools (Right-Click > Inspect) or (Menu > More Tools > Developer Tools)
2. Next, go to the Refresh button in Chrome browser, and Right-Click the Refresh button.
3. Select "Empty Cache and Hard Refresh".

Hope this answer helps someone!

In addition to all the options listed by other answers, you can use git reset with the Git object (hash, branch, HEAD~x, tag, ...) of interest and the path of your file:

git reset <hash> /path/to/file

In your example:

git reset 27cf8e8 my_file.txt

What this does is that it will revert my_file.txt to its version at the commit 27cf8e8 in the index while leaving it untouched (so in its current version) in the working directory.

From there, things are very easy:

• you can compare the two versions of your file with git diff --cached my_file.txt
• you can get rid of the old version of the file with git restore --staged file.txt (or, prior to Git v2.23, git reset file.txt) if you decide that you don't like it
• you can restore the old version with git commit -m "Restore version of file.txt from 27cf8e8" and git restore file.txt (or, prior to Git v2.23, git checkout -- file.txt)
• you can add updates from the old to the new version only for some hunks by running git add -p file.txt (then git commit and git restore file.txt).

Lastly, you can even interactively pick and choose which hunk(s) to reset in the very first step if you run:

git reset -p 27cf8e8 my_file.txt

So git reset with a path gives you lots of flexibility to retrieve a specific version of a file to compare with its currently checked-out version and, if you choose to do so, to revert fully or only for some hunks to that version.

Edit: I just realized that I am not answering your question since what you wanted wasn't a diff or an easy way to retrieve part or all of the old version but simply to cat that version.

Of course, you can still do that after resetting the file with:

git show :file.txt

to output to standard output or

git show :file.txt > file_at_27cf8e8.txt

But if this was all you wanted, running git show directly with git show 27cf8e8:file.txt as others suggested is of course much more direct.

I am going to leave this answer though because running git show directly allows you to get that old version instantly, but if you want to do something with it, it isn't nearly as convenient to do so from there as it is if you reset that version in the index.

By MSDN

The .NET Framework includes the following three predefined IFormatProvider implementations to provide culture-specific information that is used in formatting or parsing numeric and date and time values:

1. The NumberFormatInfo class, which provides information that is used to format numbers, such as the currency, thousands separator, and decimal separator symbols for a particular culture. For information about the predefined format strings recognized by a NumberFormatInfo object and used in numeric formatting operations, see Standard Numeric Format Strings and Custom Numeric Format Strings.
2. The DateTimeFormatInfo class, which provides information that is used to format dates and times, such as the date and time separator symbols for a particular culture or the order and format of a date's year, month, and day components. For information about the predefined format strings recognized by a DateTimeFormatInfo object and used in numeric formatting operations, see Standard Date and Time Format Strings and Custom Date and Time Format Strings.
3. The CultureInfo class, which represents a particular culture. Its GetFormat method returns a culture-specific NumberFormatInfo or DateTimeFormatInfo object, depending on whether the CultureInfo object is used in a formatting or parsing operation that involves numbers or dates and times.

The .NET Framework also supports custom formatting. This typically involves the creation of a formatting class that implements both IFormatProvider and ICustomFormatter. An instance of this class is then passed as a parameter to a method that performs a custom formatting operation, such as String.Format(IFormatProvider, String, Object[]).

You could do:

class myClass : ICloneable
{
    public String test;
    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

then you can do

myClass a = new myClass();
myClass b = (myClass)a.Clone();

N.B. MemberwiseClone() Creates a shallow copy of the current System.Object.

Dim input As String

input = InputBox("Enter something:")

If StrPtr(input) = 0 Then
   MsgBox "You pressed cancel!"
Elseif input.Length = 0 Then
   MsgBox "OK pressed but nothing entered."
Else
   MsgBox "OK pressed: value= " & input
End If

This workflow works best for me:

git checkout -b develop

...make some changes...

...notice master has been updated...

...commit changes to develop...

git checkout master
git pull

...bring those changes back into develop...

git checkout develop
git rebase master

...make some more changes...

...commit them to develop...

...merge them into master...

git checkout master
git pull
git merge develop

Also, make sure your branch is clean and there is nothing unstaged you can check with git status stash or commit the changes then run the comand

In fact, when using generic on interface, the keyword is also extends. Here is the code example:

There are 2 classes that implements the Greeting interface:

interface Greeting {
    void sayHello();
}

class Dog implements Greeting {
    @Override
    public void sayHello() {
        System.out.println("Greeting from Dog: Hello ");
    }
}

class Cat implements Greeting {
    @Override
    public void sayHello() {
        System.out.println("Greeting from Cat: Hello ");
    }
}

And the test code:

@Test
public void testGeneric() {
    Collection<? extends Greeting> animals;

    List<Dog> dogs = Arrays.asList(new Dog(), new Dog(), new Dog());
    List<Cat> cats = Arrays.asList(new Cat(), new Cat(), new Cat());

    animals = dogs;
    for(Greeting g: animals) g.sayHello();

    animals = cats;
    for(Greeting g: animals) g.sayHello();
}

If you're using cygwin or some minimal shell that lacks killall you can just use this script:

killall.sh - Kill by process name.

#/bin/bash
ps -W | grep "$1" | awk '{print $1}' | xargs kill --

Usage:

$ killall <process name>

Application.Current results in an appdomain http://msdn.microsoft.com/en-us/library/system.appdomain_members.aspx

Also this should give you the location of the assembly

AppDomain.CurrentDomain.BaseDirectory

I seem to recall there being multiple ways of getting the location of the application. but this one worked for me in the past atleast (it's been a while since i've done winforms programming :/)

Since I am new to stackoverflow and have lesser reputation to comment on others' answers, I am putting the solution suggested by Chris Salij with some modification which worked for me.

            SSLContext ctx = null;
            TrustManager[] trustAllCerts = new X509TrustManager[]{new X509TrustManager(){
                public X509Certificate[] getAcceptedIssuers(){return null;}
                public void checkClientTrusted(X509Certificate[] certs, String authType){}
                public void checkServerTrusted(X509Certificate[] certs, String authType){}
            }};
            try {
                ctx = SSLContext.getInstance("SSL");
                ctx.init(null, trustAllCerts, null);
            } catch (NoSuchAlgorithmException | KeyManagementException e) {
                LOGGER.info("Error loading ssl context {}", e.getMessage());
            }

            SSLContext.setDefault(ctx);

You can use it in the same datafram (df) using the previously provided code

df[!grepl("REVERSE", df$Name),]

or you might assign a different name to the datafram using this code

df1<-df[!grepl("REVERSE", df$Name),]

You can do this:

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

and most of it will work (although MS support will tell you that doing this is not supported because it bypasses RBAC).

I've seen issues with some cmdlets (specifically enable/disable UMmailbox) not working with just the snapin loaded.

In Exchange 2010, they basically don't support using Powershell outside of the the implicit remoting environment of an actual EMS shell.

I'm working on Crud for my app. This is how I did it Got Reactstrap as my dependency.

import React, { useState, setState } from 'react';
import 'bootstrap/dist/css/bootstrap.min.css';
import firebase from 'firebase';
// import { LifeCrud } from '../CRUD/Crud';
import { Row, Card, Col, Button } from 'reactstrap';
import InsuranceActionInput from '../CRUD/InsuranceActionInput';

const LifeActionCreate = () => {
  let [newLifeActionLabel, setNewLifeActionLabel] = React.useState();

  const onCreate = e => {
    const db = firebase.firestore();

    db.collection('actions').add({
      label: newLifeActionLabel
    });
    alert('New Life Insurance Added');
    setNewLifeActionLabel('');
  };

  return (
    <Card style={{ padding: '15px' }}>
      <form onSubmit={onCreate}>
        <label>Name</label>
        <input
          value={newLifeActionLabel}
          onChange={e => {
            setNewLifeActionLabel(e.target.value);
          }}
          placeholder={'Name'}
        />

        <Button onClick={onCreate}>Create</Button>
      </form>
    </Card>
  );
};

Some React Hooks in there

The views are probably created using the WITH SCHEMABINDING option and this means they are explicitly wired up to prevent such changes. Looks like the schemabinding worked and prevented you from breaking those views, lucky day, heh? Contact your database administrator and ask him to do the change, after it asserts the impact on the database.

From MSDN:

SCHEMABINDING

Binds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the base table or tables cannot be modified in a way that would affect the view definition. The view definition itself must first be modified or dropped to remove dependencies on the table that is to be modified.

Brightness and contrast can be adjusted using alpha (a) and beta (ß), respectively. The expression can be written as

OpenCV already implements this as cv2.convertScaleAbs(), just provide user defined alpha and beta values

import cv2

image = cv2.imread('1.jpg')

alpha = 1.5 # Contrast control (1.0-3.0)
beta = 0 # Brightness control (0-100)

adjusted = cv2.convertScaleAbs(image, alpha=alpha, beta=beta)

cv2.imshow('original', image)
cv2.imshow('adjusted', adjusted)
cv2.waitKey()

Before -> After

Note: For automatic brightness/contrast adjustment take a look at automatic contrast and brightness adjustment of a color photo

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

All those settings are necessary to choose which tags you are interested in, but in order to display these tags in a list, you also need to select the right Eclipse perspective. I finally discovered that the "Markers" tab containing the "Task" list is only available under the "Java EE" perspective... Hope this helps! :-)

In your Manifest define windowSoftInputMode property:

<activity android:name=".MyActivity"
          android:windowSoftInputMode="adjustNothing">

I think the best way to add comments to a CSV file would be to add a "Comments" field or record right into the data.

Most CSV-parsing applications that I've used implement both field-mapping and record-choosing. So, to comment on the properties of a field, add a record just for field descriptions. To comment on a record, add a field at the end of it (well, all records, really) just for comments.

These are the only two reasons I can think of to comment a CSV file. But the only problem I can foresee would be programs that refuse to accept the file at all if any single record doesn't pass some validation rules. In that case, you'd have trouble writing a string-type field description record for any numeric fields.

I am by no means an expert, though, so feel free to point out any mistakes in my theory.

I use LEd Editor with special "Filter" feature. It replaces \"{o} with ö and vice versa in its own editor, while maintaining original \"{o} in tex files. This makes text easily readable when viewed in LEd Editor and there is no need for special packages. It works with bibliography files too.

Use one of these threee variants:

SOME_PATH="/mnt/someProject/some path"
SOME_PATH='/mnt/someProject/some path'
SOME_PATH=/mnt/someProject/some\ path

calling [self.view setNeedsLayout]; in viewController makes it to call viewDidLayoutSubviews

Create a Random object with a seed and get the array random by doing:

public static final int ARRAY_LENGTH = 20;

byte[] byteArray = new byte[ARRAY_LENGTH];
new Random(System.currentTimeMillis()).nextBytes(byteArray);
// get fisrt element
System.out.println("Random byte: " + byteArray[0]);

You need to identify the primary key in TableA in order to delete the correct record. The primary key may be a single column or a combination of several columns that uniquely identifies a row in the table. If there is no primary key, then the ROWID pseudo column may be used as the primary key.

DELETE FROM tableA
WHERE ROWID IN 
  ( SELECT q.ROWID
    FROM tableA q
      INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
    WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
      AND (u.FldFormat = 'Date'));

You can try this way -

ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
    duration = 2000
    start()
}

Note - view is your view where you want animation.

The Range object has both width and height properties, which are measured in points.

@user20877984's answer is excellent. Since they summed it up far better than my previous answer, here is my (posibly still shoddy) attempt at an application of the concept:

Using do.call in a basic fashion:

powvalues <- list(power=0.9,delta=2)
do.call(power.t.test,powvalues)

Working on a full data set:

# get the example data
df <- data.frame(delta=c(1,1,2,2), power=c(.90,.85,.75,.45))

#> df
#  delta power
#1     1  0.90
#2     1  0.85
#3     2  0.75
#4     2  0.45

lapply the power.t.test function to each of the rows of specified values:

result <- lapply(
  split(df,1:nrow(df)),
  function(x) do.call(power.t.test,x)
)

> str(result)
List of 4
 $ 1:List of 8
  ..$ n          : num 22
  ..$ delta      : num 1
  ..$ sd         : num 1
  ..$ sig.level  : num 0.05
  ..$ power      : num 0.9
  ..$ alternative: chr "two.sided"
  ..$ note       : chr "n is number in *each* group"
  ..$ method     : chr "Two-sample t test power calculation"
  ..- attr(*, "class")= chr "power.htest"
 $ 2:List of 8
  ..$ n          : num 19
  ..$ delta      : num 1
  ..$ sd         : num 1
  ..$ sig.level  : num 0.05
  ..$ power      : num 0.85

Newer versions of pandas do allow you to pass extra arguments (see the new documentation). So now you can do:

my_series.apply(your_function, args=(2,3,4), extra_kw=1)

The positional arguments are added after the element of the series.

For older version of pandas:

The documentation explains this clearly. The apply method accepts a python function which should have a single parameter. If you want to pass more parameters you should use functools.partial as suggested by Joel Cornett in his comment.

An example:

>>> import functools
>>> import operator
>>> add_3 = functools.partial(operator.add,3)
>>> add_3(2)
5
>>> add_3(7)
10

You can also pass keyword arguments using partial.

Another way would be to create a lambda:

my_series.apply((lambda x: your_func(a,b,c,d,...,x)))

But I think using partial is better.

To clarify, the above example does work, my code in the example did not work for unrelated reasons.

If myvar is false, null or has never been used before (i.e. $scope.myvar or $rootScope.myvar never called), the div will not show. Once any value has been assigned to it, the div will show, except if the value is specifically false.

The following will cause the div to show:

$scope.myvar = "Hello World";

or

$scope.myvar = true;

The following will hide the div:

$scope.myvar = null;

or

$scope.myvar = false;

There is another approach you can take depending on how you're using your collection. If you're downloading the assignments one time (e.g., when the app runs), you could translate the collection on the fly into a hashtable where:

shortname => SPRoleAssignment

If you do this, then when you want to remove an item by short name, all you need to do is remove the item from the hashtable by key.

Unfortunately, if you're loading these SPRoleAssignments a lot, that obviously isn't going to be any more cost efficient in terms of time. The suggestions other people made about using Linq would be good if you're using a new version of the .NET Framework, but otherwise, you'll have to stick to the method you're using.

Try an OutputStream or more specifically FileOutputStream

Is the size of C “int” 2 bytes or 4 bytes?

The answer is "yes" / "no" / "maybe" / "maybe not".

The C programming language specifies the following: the smallest addressable unit, known by char and also called "byte", is exactly CHAR_BIT bits wide, where CHAR_BIT is at least 8.

So, one byte in C is not necessarily an octet, i.e. 8 bits. In the past one of the first platforms to run C code (and Unix) had 4-byte int - but in total int had 36 bits, because CHAR_BIT was 9!

int is supposed to be the natural integer size for the platform that has range of at least -32767 ... 32767. You can get the size of int in the platform bytes with sizeof(int); when you multiply this value by CHAR_BIT you will know how wide it is in bits.

While 36-bit machines are mostly dead, there are still platforms with non-8-bit bytes. Just yesterday there was a question about a Texas Instruments MCU with 16-bit bytes, that has a C99, C11-compliant compiler.

On TMS320C28x it seems that char, short and int are all 16 bits wide, and hence one byte. long int is 2 bytes and long long int is 4 bytes. The beauty of C is that one can still write an efficient program for a platform like this, and even do it in a portable manner!

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

By psql --help, when you didn't set options for database name (without -d option) it would be your username, if you didn't do -U, the database username would be your username too, etc.

But by initdb (to create the first database) command it doesn't have your username as any database name. It has a database named postgres. The first database is always created by the initdb command when the data storage area is initialized. This database is called postgres.

So if you don't have another database named your username, you need to do psql -d postgres for psql command to work. And it seems it gives -d option by default, psql postgres also works.

If you have created another database names the same to your username, (it should be done with createdb) then you may command psql only. And it seems the first database user name sets as your machine username by brew.

psql -d <first database name> -U <first database user name>

or,

psql -d postgres -U <your machine username>
psql -d postgres

would work by default.

If you're concerned the number of rows that meet the condition may change in the few milliseconds since execution of the query and retrieval of results, you could/should execute the queries inside a transaction:

BEGIN TRAN bogus

SELECT COUNT( my_table.my_col ) AS row_count
FROM my_table
WHERE my_table.foo = 'bar'

SELECT my_table.my_col
FROM my_table
WHERE my_table.foo = 'bar'
ROLLBACK TRAN bogus

This would return the correct values, always.

Furthermore, if you're using SQL Server, you can use @@ROWCOUNT to get the number of rows affected by last statement, and redirect the output of real query to a temp table or table variable, so you can return everything altogether, and no need of a transaction:

DECLARE @dummy INT

SELECT my_table.my_col
INTO #temp_table
FROM my_table
WHERE my_table.foo = 'bar'

SET @dummy=@@ROWCOUNT
SELECT @dummy, * FROM #temp_table

Instead of using:

void parameterizedMethod(String param1, int param2) {
    this(param1, param2, false);
}

void parameterizedMethod(String param1, int param2, boolean param3) {
    //use all three parameters here
}

You could utilize java's Optional functionality by having a single method:

void parameterizedMethod(String param1, int param2, @Nullable Boolean param3) {
    param3 = Optional.ofNullable(param3).orElse(false);
    //use all three parameters here
}

The main difference is that you have to use wrapper classes instead of primitive Java types to allow null input.Boolean instead of boolean, Integer instead of int and so on.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

This can be accomplished by Unmarshaling into a map[string]json.RawMessage.

var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)

To further parse sendMsg, you could then do something like:

var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)

For say, you can do the same thing and unmarshal into a string:

var str string
err = json.Unmarshal(objmap["say"], &str)

EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:

type sendMsg struct {
    User string
    Msg  string
}

Example: https://play.golang.org/p/OrIjvqIsi4-

Your question almost spells the SQL for this:

DELETE FROM table WHERE id IN (1, 4, 6, 7)

Note that the ::first-letter selector does not work with inline elements, so it must be either block or inline-block, as follows:

.m_title {display:inline-block}
.m_title:first-letter {text-transform: uppercase}

You need to actually define the static member somewhere (after the class definition). Try this:

class Foo { /* ... */ };

const int Foo::MEMBER;

int main() { /* ... */ }

That should get rid of the undefined reference.

To print address in pointer to pointer:

printf("%p",emp1)

to dereference once and print the second address:

printf("%p",*emp1)

You can always verify with debugger, if you are on linux use ddd and display memory, or just plain gdb, you will see the memory address so you can compare with the values in your pointers.

One way is to just leave merged feature branches open (and inactive):

$ hg up default
$ hg merge feature-x
$ hg ci -m merge

$ hg heads
    (1 head)

$ hg branches
default    43:...
feature-x  41:...
    (2 branches)

$ hg branches -a
default    43:...
    (1 branch)

Another way is to close a feature branch before merging using an extra commit:

$ hg up feature-x
$ hg ci -m 'Closed branch feature-x' --close-branch
$ hg up default
$ hg merge feature-x
$ hg ci -m merge

$ hg heads
    (1 head)

$ hg branches
default    43:...
    (1 branch)

The first one is simpler, but it leaves an open branch. The second one leaves no open heads/branches, but it requires one more auxiliary commit. One may combine the last actual commit to the feature branch with this extra commit using --close-branch, but one should know in advance which commit will be the last one.

Update: Since Mercurial 1.5 you can close the branch at any time so it will not appear in both hg branches and hg heads anymore. The only thing that could possibly annoy you is that technically the revision graph will still have one more revision without childen.

Update 2: Since Mercurial 1.8 bookmarks have become a core feature of Mercurial. Bookmarks are more convenient for branching than named branches. See also this question:

• Mercurial branching and bookmarks

Now Microsoft is migrating to open-source - see CoreFX (GitHub).

If your button is loading from an AJAX call, you should use

$(document).on("click", ".delegate_update_success", function(){
    location.reload(true);
});

instead of

$( ".delegate_update_success" ).click(function() {
    location.reload();
});

Also note the true parameter for the location.reload function.

it should be sending a POST if you provide a data parameter (like you are doing):

from the docs: "the HTTP request will be a POST instead of a GET when the data parameter is provided"

so.. add some debug output to see what's up from the client side.

you can modify your code to this and try again:

import urllib
import urllib2

url = 'http://myserver/post_service'
opener = urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1))
data = urllib.urlencode({'name' : 'joe',
                         'age'  : '10'})
content = opener.open(url, data=data).read()

The TFS Preview login apparently uses Internet Explorer and thus might conflict with other MS Accounts you are using. Fully clearing the IE cache seems to work for me. After the cache clearing, I get to the correct login screen and may enter my credentials as needed.

now include bootstrap 4:

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.3/css/bootstrap.min.css');

and code should be like this:

<div class="row">
    <div class="col-lg-6 col-md-6" style="border:solid 1px red">elements 1</div>
    <div class="col-lg-6 col-md-6" style="border:solid 1px red">
         <div class="pull-lg-right pull-xl-right">
            elements 2
         </div>
    </div>
</div>

This worked for me:

First, go to

cd /etc/nginx

and make the changes in nginx.conf and make the default port to listen from 80 to any of your choice 85 or something.

Then use this command to bind that port type for nginx to use it:

semanage port -a -t PORT_TYPE -p tcp 85

where PORT_TYPE is one of the following: http_cache_port_t, http_port_t, jboss_management_port_t, jboss_messaging_port_t, ntop_port_t, puppet_port_t.

Then run:

sudo systemctl start nginx; #sudo systemctl status nginx

[you should see active status]; #sudo systemctl enable nginx

their is no need to create asset directory and under it images directory and then you put image. Better is to just create Images directory inside your project where pubspec.yaml exist and put images inside it and access that images just like as shown in tutorial/documention

assets: - images/lake.jpg // inside pubspec.yaml

Query 1: SELECT * FROM yourtable WHERE id > 0 ORDER BY id LIMIT 500

Query 2: SELECT * FROM tbl LIMIT 0,500;

Query 1 run faster with small or medium records, if number of records equal 5,000 or higher, the result are similar.

Result for 500 records:

Query1 take 9.9999904632568 milliseconds

Query2 take 19.999980926514 milliseconds

Result for 8,000 records:

Query1 take 129.99987602234 milliseconds

Query2 take 160.00008583069 milliseconds

i use jquery to send the data when the user press the like button.

<script>
  window.fbAsyncInit = function() {
    FB.init({appId: 'xxxxxxxxxxxxx', status: true, cookie: true,
             xfbml: true});

                 FB.Event.subscribe('edge.create', function(href, widget) {
$(document).ready(function() { 

var h_fbl=href.split("/");
var fbl_id= h_fbl[4]; 


 $.post("http://xxxxxx.com/inc/like.php",{ idfb:fbl_id,rand:Math.random() } )

}) });
  };

</script>

Note:you can use some hidden input text to get the id of your button.in my case i take it from the url itself in "var fbl_id=h_fbl[4];" becasue there is the id example: url: http://mywebsite.com/post/22/some-tittle

so i parse the url to get the id and then insert it to my databse in the like.php file. in this way you dont need to ask for permissions to know if some one press the like button, but if you whant to know who press it, permissions are needed.

The following solution worked for me in Bootstrap 3.3.4:

CSS:

/*no collapse*/

.navbar-collapse.collapse.off {
    display: block!important;
}
.navbar-collapse.collapse.off ul {
    margin: 0;
    padding: 0;
}

.navbar-nav.no-collapse>li,
.navbar-nav.no-collapse {
    float: left !important;
}

.navbar-right.no-collapse {
    float: right!important;
}

then add the .no-collapse class to each of the lists and the .off class to the main container. Here is an example written in jade:

nav.navbar.navbar-default.navbar-fixed-top
        .container-fluid
            .collapse.navbar-collapse.off
                ul.nav.navbar-nav.no-collapse
                    li
                        a(href='#' class='glyph')
                            i(class='glyphicon glyphicon-info-sign')
                ul.nav.navbar-nav.navbar-right.no-collapse
                    li.dropdown
                        a.dropdown-toggle(href='#', data-toggle='dropdown' role='button' aria-expanded='false')
                            | Tools
                            span.caret
                        ul.dropdown-menu(role='menu')
                            li
                                a(href='#') Tool #1
                    li
                        a(href='#')
                            | Logout

Surely using your own panel or form would be by far the simplest approach if a little more heavy on the background (designer) code. It gives all the control in terms of centring and manipulation without writing all that custom code.

Just set this to v21/styles.xml file

 <item name="android:windowDrawsSystemBarBackgrounds">true</item>
 <item name="android:statusBarColor">@color/colorPrimaryDark</item>

and be sure

 <item name="android:windowTranslucentStatus">false</item>

No. Neither Visual Studio or the .NET framework will run on Mac OSX (although the latter is changing). However, if you want to write an application in a similar framework, you could use Mono and MonoDevelop.

On Android 4.4 KitKat, I found mine in: /sdcard/Android/data/<app.package.name>

Your real problem is that you are calling "sc.nextLine()" MORE TIMES than the number of lines.

For example, if you have only TEN input lines, then you can ONLY call "sc.nextLine()" TEN times.

Every time you call "sc.nextLine()", one input line will be consumed. If you call "sc.nextLine()" MORE TIMES than the number of lines, you will have an exception called

      "java.util.NoSuchElementException: No line found".

If you have to call "sc.nextLine()" n times, then you have to have at least n lines.

Try to change your code to match the number of times you call "sc.nextLine()" with the number of lines, and I guarantee that your problem will be solved.

Slightly alternative solution to @jpp's but outputting a YearMonth string:

df['YearMonth'] = pd.to_datetime(df['Date']).apply(lambda x: '{year}-{month}'.format(year=x.year, month=x.month))

res = df.groupby('YearMonth')['Values'].sum()

A slightly different approach that may or may not be useful for you.

I'm in php.

The project this relates to will never have a date prior to the 1st of January 2008. So, I take the 'date' inputed and use strtotime(). If the answer is >= 1199167200 then I have a date that is useful to me. If something that doesn't look like a date is entered -1 is returned. If null is entered it does return today's date number so you do need a check for a non-null entry first.

Works for my situation, perhaps yours too?

Check the encoding in which you are generating the file, to make excel display the file correctly you must use the system default codepage.

Wich language are you using? if it's .Net you only need to use Encoding.Default while generating the file.

Sure is:

@media screen and (-webkit-min-device-pixel-ratio:0)
{ 
    #element { properties:value; } 
}

And a little fiddle to see it in action - http://jsfiddle.net/Hey7J/

Must add tho... this is generally bad practice, you shouldn't really be at the point where you start to need individual browser hacks to make you CSS work. Try using reset style sheets at the start of your project, to help avoid this.

Also, these hacks may not be future proof.

The activity in which you want to add listview footer and i have also generate an event on listview footer click.

  public class MainActivity extends Activity
{

        @Override
        protected void onCreate(Bundle savedInstanceState)
         {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            ListView  list_of_f = (ListView) findViewById(R.id.list_of_f);

            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View view = inflater.inflate(R.layout.web_view, null);  // i have open a webview on the listview footer

            RelativeLayout  layoutFooter = (RelativeLayout) view.findViewById(R.id.layoutFooter);

            list_of_f.addFooterView(view);

        }

}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg" >

    <ImageView
        android:id="@+id/dept_nav"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/dept_nav" />

    <ListView
        android:id="@+id/list_of_f"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/dept_nav"
        android:layout_margin="5dp"
        android:layout_marginTop="10dp"
        android:divider="@null"
        android:dividerHeight="0dp"
        android:listSelector="@android:color/transparent" >
    </ListView>

</RelativeLayout>

As far as I have found, this expression is good for me-

(https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}|https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9]\.[^\s]{2,}|www\.[a-zA-Z0-9]\.[^\s]{2,})

Working example-

function RegExForUrlMatch()_x000D_
{_x000D_
  var expression = /(https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}|https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9]\.[^\s]{2,}|www\.[a-zA-Z0-9]\.[^\s]{2,})/g;_x000D_
_x000D_
  var regex = new RegExp(expression);_x000D_
  var t = document.getElementById("url").value;_x000D_
_x000D_
  if (t.match(regex)) {_x000D_
    document.getElementById("demo").innerHTML = "Successful match";_x000D_
  } else {_x000D_
    document.getElementById("demo").innerHTML = "No match";_x000D_
  }_x000D_
}

<input type="text" id="url" placeholder="url" onkeyup="RegExForUrlMatch()">_x000D_
_x000D_
<p id="demo">Please enter a URL to test</p>

Making setState return a Promise

In addition to passing a callback to setState() method, you can wrap it around an async function and use the then() method -- which in some cases might produce a cleaner code:

(async () => new Promise(resolve => this.setState({dummy: true}), resolve)()
    .then(() => { console.log('state:', this.state) });

And here you can take this one more step ahead and make a reusable setState function that in my opinion is better than the above version:

const promiseState = async state =>
    new Promise(resolve => this.setState(state, resolve));

promiseState({...})
    .then(() => promiseState({...})
    .then(() => {
        ...  // other code
        return promiseState({...});
    })
    .then(() => {...});

This works fine in React 16.4, but I haven't tested it in earlier versions of React yet.

Also worth mentioning that keeping your callback code in componentDidUpdate method is a better practice in most -- probably all, cases.

You use the String.format() method.

The question mark is the conditional operator. The code means that if f==r then 1 is returned, otherwise, return 0. The code could be rewritten as

int qempty()
{
  if(f==r)
    return 1;
  else
    return 0;
}

which is probably not the cleanest way to do it, but hopefully helps your understanding.

Following previous posts, here is the full list I used

sudo npm uninstall npm -g
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*
sudo rm -rf /usr/local/include/node /Users/$USER/.npm
sudo rm /usr/local/bin/node
sudo rm /usr/local/share/man/man1/node.1
sudo rm /usr/local/lib/dtrace/node.d
brew install node

Try this ,

<img src= "@Url.Content(Model.ImagePath)" alt="Sample Image" style="height:50px;width:100px;"/>

(or)

<img src="~/Content/img/@Url.Content(model =>model.ImagePath)" style="height:50px;width:100px;"/>

To read json response use json.loads(). Here is the sample.

import json
import urllib
import urllib2

post_params = {
    'foo' : bar
}

params = urllib.urlencode(post_params)
response = urllib2.urlopen(url, params)
json_response = json.loads(response.read())

You can configure a proxy with conda by adding it to the .condarc, like

proxy_servers:
    http: http://user:[email protected]:8080
    https: https://user:[email protected]:8080

Then in cmd Anaconda Power Prompt (base) PS C:\Users\user> run:

conda update -n root conda

This is visual representation of how performances compare to each other.

Modern Approach

Simply make your input readonly, and on focus, remove it. This is a very simple approach and browsers will not populate readonly inputs. Therefore, this method is accepted and will never be overwritten by future browser updates.

<input type="text" onfocus="this.removeAttribute('readonly');" readonly />

The next part is optional. Style your input accordingly so that it does not look like a readonly input.

input[readonly] {
     cursor: text;
     background-color: #fff;
}

WORKING EXAMPLE

It looks like the following code works fine. But in some cases, this doesn't work.

sendButton.enabled = NO;
sendButton.alpha = 0.5;

If the above code doesn't work, please wrap it in Main Thread. so

dispatch_async(dispatch_get_main_queue(), ^{
    sendButton.enabled = NO;
    sendButton.alpha = 0.5
});

if you go with swift, like this

DispatchQueue.main.async {
    sendButton.isEnabled = false
    sendButton.alpha = 0.5
}

In addition, if you customized UIButton, add this to the Button class.

override var isEnabled: Bool {
    didSet {
        DispatchQueue.main.async {
            if self.isEnabled {
                self.alpha = 1.0
            }
            else {
                self.alpha = 0.5
            }
        }
    }
}

Thank you and enjoy coding!!!

You could use the ngSwitch directive:

  <div ng-switch on="selection" >
    <div ng-switch-when="settings">Settings Div</div>
    <span ng-switch-when="home">Home Span</span>
    <span ng-switch-default>default</span>
  </div>

If you don't want the DOM to be loaded with empty divs, you need to create your custom directive using $http to load the (sub)templates and $compile to inject it in the DOM when a certain condition has reached.

This is just an (untested) example. It can and should be optimized:

HTML:

<conditional-template ng-model="element" template-url1="path/to/partial1" template-url2="path/to/partial2"></div>

Directive:

app.directive('conditionalTemplate', function($http, $compile) {
   return {
      restrict: 'E',
      require: '^ngModel',
      link: function(sope, element, attrs, ctrl) {
        // get template with $http
        // check model via ctrl.$viewValue
        // compile with $compile
        // replace element with element.replaceWith()
      }
   };
});

In my case it was due to a multi-line rule error in the Makefile. I had something like:

OBJS-$(CONFIG_OBJ1)            += file1.o file2.o \
                                  file3.o file4.o \
OBJS-$(CONFIG_OBJ2)            += file5.o 
OBJS-$(CONFIG_OBJ3)            += file6.o
...

The backslash at the end of file list in CONFIG_OBJ1's rule caused this error. It should be like:

OBJS-$(CONFIG_OBJ1)            += file1.o file2.o \
                                  file3.o file4.o
OBJS-$(CONFIG_OBJ2)            += file5.o
...

If you're interested in the pure string:

[myUrl absoluteString];

If you're interested in the path represented by the URL (and to be used with NSFileManager methods for example):

[myUrl path];

I faced the same problem but When I changed the skin of AVD device to HVGA, it worked.

I found a generic and simple way to do that. In my class I created a method that returns the generic type according to it's position in the class definition. Let's assume a class definition like this:

public class MyClass<A, B, C> {

}

Now let's create some attributes to persist the types:

public class MyClass<A, B, C> {

    private Class<A> aType;

    private Class<B> bType;

    private Class<C> cType;

// Getters and setters (not necessary if you are going to use them internally)

    } 

Then you can create a generic method that returns the type based on the index of the generic definition:

   /**
     * Returns a {@link Type} object to identify generic types
     * @return type
     */
    private Type getGenericClassType(int index) {
        // To make it use generics without supplying the class type
        Type type = getClass().getGenericSuperclass();

        while (!(type instanceof ParameterizedType)) {
            if (type instanceof ParameterizedType) {
                type = ((Class<?>) ((ParameterizedType) type).getRawType()).getGenericSuperclass();
            } else {
                type = ((Class<?>) type).getGenericSuperclass();
            }
        }

        return ((ParameterizedType) type).getActualTypeArguments()[index];
    }

Finally, in the constructor just call the method and send the index for each type. The complete code should look like:

public class MyClass<A, B, C> {

    private Class<A> aType;

    private Class<B> bType;

    private Class<C> cType;


    public MyClass() {
      this.aType = (Class<A>) getGenericClassType(0);
      this.bType = (Class<B>) getGenericClassType(1);
      this.cType = (Class<C>) getGenericClassType(2);
    }

   /**
     * Returns a {@link Type} object to identify generic types
     * @return type
     */
    private Type getGenericClassType(int index) {

        Type type = getClass().getGenericSuperclass();

        while (!(type instanceof ParameterizedType)) {
            if (type instanceof ParameterizedType) {
                type = ((Class<?>) ((ParameterizedType) type).getRawType()).getGenericSuperclass();
            } else {
                type = ((Class<?>) type).getGenericSuperclass();
            }
        }

        return ((ParameterizedType) type).getActualTypeArguments()[index];
    }
}

Some action, very possibly not represented in the visible code, has closed the interactive screen device. It could be done either by a "click" on a close-button. (Could also be done by an extra dev.off() when plotting to a file-graphics device. This may happen if you paste in a mult-line plotting command that has a dev,off() at the end of it but errors out at the opening of the external device but then has hte dev.off() on a separate line so it accidentally closes the interactive device).

Some (most?) R implementations will start up a screen graphics device open automatically, but if you close it down, you then need to re-initialize it. On Windows that might be window(); on a Mac, quartz(); and on a linux box, x11(). You also may need to issue a plot.new() command. I just follow orders. When I get that error I issue plot.new() and if I don't see a plot window, I issue quartz() as well. I then start over from the beginning with a new plot(., ., ...) command and any further additions to that plot screen image.

You don't have to include String twice, and you don't have to use New.
Either of the following will work...

Dim strings() as String = {}
Dim strings as String() = {}

You have to put your .exe file's path into enviroment variable path. Go to "My computer -> properties -> advanced -> environment variables -> Path" and edit path by adding .exe's directory into path.

Another solution I personally prefer is using RapidEE for a smoother variable editing.

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

I meet the same problem and no one of the solutions detailed here worked for me ... First of all I had an error 413 Entity too large so I updated my nginx.conf as following :

http {
        # Increase request size
        client_max_body_size 10m;

        ##
        # Basic Settings

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;

        proxy_send_timeout 1000;
        proxy_read_timeout 1000;
        send_timeout 1000;
}

So I only updated the http part, and now I meet the error 502 Bad Gateway and when I display /var/log/nginx/error.log I got the famous "upstream prematurely closed connection while reading response header from upstream"

What is really mysterious for me is that the request works when I run it with virtualenv on my server and send the request to the : IP:8000/nameOfTheRequest

Thanks for reading

With Python 3.7 I could do this:

>>> myDic={10: 'b', 3:'a', 5:'c'}
>>> sortDic = sorted(myDic.items())
>>> print(dict(sortDic))
{3:'a', 5:'c', 10: 'b'}

If you want a list of tuples:

>>> myDic={10: 'b', 3:'a', 5:'c'}
>>> sortDic = sorted(myDic.items())
>>> print(sortDic)
[(3, 'a'), (5, 'c'), (10, 'b')]

Does it work if you escape the quoted commas with \ ?

Name, Age, Sex

"Cantor\, Georg", 163,M

Most delimited formats require that their delimiter be escaped in order to properly parse.

A rough Java example:

import java.util.Iterator;

public class CsvTest {

    public static void main(String[] args) {
        String[] lines = { "Name, Age, Sex", "\"Cantor, Georg\", 163, M" };

        StringBuilder result = new StringBuilder();

        for (String head : iterator(lines[0])) {
            result.append(String.format("<tr>%s</tr>\n", head));
        }

        for (int i=1; i < lines.length; i++) {
            for (String row : iterator(lines[i])) {
                result.append(String.format("<td>%s</td>\n", row));

If you don't want execute assembly goal on package, you can use next command:

mvn package assembly:single

Here package is keyword.

This answer is for Mongo 3.2.1 Reference

Terminal 1:

$ mongod --auth

Terminal 2:

db.createUser({user:"admin_name", pwd:"1234",roles:["readWrite","dbAdmin"]})

if you want to add without roles (optional):

db.createUser({user:"admin_name", pwd:"1234", roles:[]})

to check if authenticated or not:

db.auth("admin_name", "1234")

it should give you:

1

else :

Error: Authentication failed.
0

Now you must import them manually.

import 'rxjs/add/operator/retry';
import 'rxjs/add/operator/timeout';
import 'rxjs/add/operator/delay';
import 'rxjs/add/operator/map';




this.http.post(url, JSON.stringify(json), {headers: headers, timeout: 1000})

         .retry(2)

         .timeout(10000, new Error('Time out.'))

         .delay(10)

         .map((res) => res.json())
        .subscribe(
          (data) => resolve(data.json()),
          (err) => reject(err)
        );

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

Related, you can use the following if you want to have a vector completely ready to go in a quick statement (e.g. immediately passing to another function):

#define VECTOR(first,...) \
   ([](){ \
   static const decltype(first) arr[] = { first,__VA_ARGS__ }; \
   std::vector<decltype(first)> ret(arr, arr + sizeof(arr) / sizeof(*arr)); \
   return ret;})()

example function

template<typename T>
void test(std::vector<T>& values)
{
    for(T value : values)
        std::cout<<value<<std::endl;
}

example use

test(VECTOR(1.2f,2,3,4,5,6));

though be careful about the decltype, make sure the first value is clearly what you want.
