In case entire entity is being return, better solution in spring JPA is use @Query(value = "from entity where Id in :ids")

This return entity type rather than object type

What worked for me was to add the file under My Project/Java Resources/src and then use

this.getClass().getClassLoader().getResourceAsStream("myfile.txt");

I didn't need to explicitly add this file to the path (adding it to /src does that apparently)

If you are using FireFox you can use the File HandleAPI

https://developer.mozilla.org/en-US/docs/Web/API/File_Handle_API

I had just tested it out and it works!

If you don't have the msi and you need the upgrade code, rather than the product code then the answer is here: How can I find the upgrade code for an installed application in C#?

I'd use

files=(*)

And then if you need data about the file, such as size, use the stat command on each file.

PEAR::Mail_Mime? Sure, PEAR dependency of (min) 2 files (just mail_mime itself if you edit it to remove the pear dependencies), but it works well. Additionally, most servers have PEAR installed to some extent, and in the best cases they have Pear/Mail and Pear/Mail_Mime. Something that cannot be said for most other libraries offering the same functionality.

You may also consider looking in to PHP's IMAP extension. It's a little more complicated, and requires more setup (not enabled or installed by default), but is must more efficient at compilng and sending messages to an IMAP capable server.

In general Shift + Tab works for any environment.

You could drop any indexes on the table, then do your insert, and then recreate the indexes.

The first one is the "short" form - you use it, when you do not want to do something fancy with your getters and setters. It is not possible to execute a method or something like that in this form.

The second and third form are almost identical, albeit the second one is compressed to one line. This form is discouraged by stylecop because it looks somewhat weird and does not conform to C' Stylguides.

I would use the third form if I expectd to use my getters / setters for something special, e.g. use a lazy construct or so.

When entering the script's full file spec or its filename on the command line, the shell will use information accessibly by

assoc | grep -i vbs
.vbs=VBSFile

ftype | grep -i vbs
VBSFile=%SystemRoot%\System32\CScript.exe "%1" %*

to decide which program to run for the script. In my case it's cscript.exe, in yours it will be wscript.exe - that explains why your WScript.Echos result in MsgBoxes.

As

cscript /?
Usage: CScript scriptname.extension [option...] [arguments...]

Options:
 //B         Batch mode: Suppresses script errors and prompts from displaying
 //D         Enable Active Debugging
 //E:engine  Use engine for executing script
 //H:CScript Changes the default script host to CScript.exe
 //H:WScript Changes the default script host to WScript.exe (default)
 //I         Interactive mode (default, opposite of //B)
 //Job:xxxx  Execute a WSF job
 //Logo      Display logo (default)
 //Nologo    Prevent logo display: No banner will be shown at execution time
 //S         Save current command line options for this user
 //T:nn      Time out in seconds:  Maximum time a script is permitted to run
 //X         Execute script in debugger
 //U         Use Unicode for redirected I/O from the console

shows, you can use //E and //S to permanently switch your default host to cscript.exe.

If you are so lazy that you don't even want to type the extension, make sure that the PATHEXT environment variable

set | grep -i vbs
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.py;.pyw;.tcl;.PSC1

contains .VBS and there is no Converter.cmd (that converts your harddisk into a washing machine) in your path.

Update wrt comment:

If you 'don't want to specify the full path of my vbscript everytime' you may:

1. put your CONVERTER.VBS in a folder that is included in the PATH environment variable; the shell will then search all pathes - if necessary taking the PATHEXT and the ftype/assoc info into account - for a matching 'executable'.
2. put a CONVERTER.BAT/.CMD into a path directory that contains a line like cscript p:\ath\to\CONVERTER.VBS

In both cases I would type out the extension to avoid (nasty) surprises.

I have tried in Python2.7.17

Some of the fellow folks already answered. However I have tried to call getattr(obj, 'set_value') and this didn't execute the set_value method, So i changed to getattr(obj, 'set_value')() --> This helps to invoke the same.

Example Code:

Example 1:

    class GETATT_VERIFY():
       name = "siva"
       def __init__(self):
           print "Ok"
       def set_value(self):
           self.value = "myself"
           print "oooh"
    obj = GETATT_VERIFY()
    print getattr(GETATT_VERIFY, 'name')
    getattr(obj, 'set_value')()
    print obj.value

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

RxJS Operators are functions that build on the observables foundation to enable sophisticated manipulation of collections.

For example, RxJS defines operators such as map(), filter(), concat(), and flatMap().

You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.

if you wanna ng-model value, if you can write like this in the triggered event: $scope.searchText

To make my future me happy: RTFM - don't use the gitlab-ci-token at all, but the .netrc file.

There are a couple of important points:

1. echo -e "machine gitlab.com\nlogin gitlab-ci-token\npassword ${CI_JOB_TOKEN}" > ~/.netrc
2. Don't forget to replace "gitlab.com" by your URL!
3. Don't try to be smart and create the .netrc file directly - gitlab will not replace the $CI_JOB_TOKEN within the file!
4. Use https://gitlab.com/whatever/foobar.com - not ssh://git@foobar, not git+ssh://, not git+https://. You also don't need any CI-TOKEN stuff in the URL.
5. Make sure you can git clone [url from step 4]

Background: I got

fatal: could not read Username for 'https://gitlab.mycompany.com': No such device or address

when I tried to make Ansible + Gitlab + Docker work as I imagine it. Now it works.

Ok, I finally found my solution.

If you are using templates on your view (using Moustache.js, or others...), you must take into account that some of your classes can be loaded twice, or will be created later. So, you must apply this function $(".datepicker" ).datepicker(); once the instance has been created.

I had a similar problem. I created a new repository, NOT IN THE DIRECTORY THAT I WANTED TO MAKE A REPOSITORY. I then copied the files created to the directory I wanted to make a repository. Then open an existing repository using the directory I just copied the files to.

NOTE: I did use github desktop to make and open exiting repository.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

When the first characters in a script are #!, that is called the shebang. If your file starts with #!/path/to/something the standard is to run something and pass the rest of the file to that program as an input.

With that said, the difference between #!/bin/bash, #!/bin/sh, or even #!/bin/zsh is whether the bash, sh, or zsh programs are used to interpret the rest of the file. bash and sh are just different programs, traditionally. On some Linux systems they are two copies of the same program. On other Linux systems, sh is a link to dash, and on traditional Unix systems (Solaris, Irix, etc) bash is usually a completely different program from sh.

Of course, the rest of the line doesn't have to end in sh. It could just as well be #!/usr/bin/python, #!/usr/bin/perl, or even #!/usr/local/bin/my_own_scripting_language.

Using internal-ip:

const internalIp = require("internal-ip")

console.log(internalIp.v4.sync())

i used the empty div solution, with this CSS:

#throbber {
    background-image: url(/Content/pictures/ajax-loader.gif);
    background-repeat: no-repeat;
    width: 48px;
    height: 48px;
    min-width: 48px;
    min-height: 48px;
}

HTML:

<div id="throbber"></div>

I would do:

((-1)+8) % 8 

This adds the latter number to the first before doing the modulo giving 7 as desired. This should work for any number down to -8. For -9 add 2*8.

If you wish to use 2 subdomains to other ports, you can use Minecraft's proxy server (it means BungeeCord, Waterfall, Travertine...), and bind subdomain to specifiend in config.yml server. To do that you have to setup your servers in BungeeCord's config:

servers:
  pvp:
    motd: 'A Minecraft Server PVP'
    address: localhost:25566
    restricted: false
  skyblock:
    motd: 'A Minecraft Server SkyBlock'
    address: localhost:25567
    restricted: false

Remember! Ports must be diffrent than default Minecraft's port (it means 25565), because we will use this port to our proxy. sub1.domain.com and sub2.domain.com we have to bind to server where you have these servers. Now, we have to bind subdomains in your Bungee server:

listeners:
    forced_hosts:
      sub1.domain.com: pvp
      sub2.domain.com: skyblock
      domain.com: pvp // You can bind other domains to same servers.

Remember to change force_default_server to true, and change host to 0.0.0.0:25565 Example of BungeeCord's config.yml with some servers: https://pastebin.com/tA9ktZ6f Now you can connect to your pvp server on sub1.domain.com and connect to skyblock on sub2.domain.com. Don't worry, BungeeCord takes only 0,5GB of RAM for 500 players.

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

There's an "edit configurations" item on the Run menu, and on the pull-down to the left of the two green "run" and "debug" arrows on the toolbar. In that panel, you create a configuration with the "+" button in the top left, and then you can choose the Class containing main(), add VM parameters and command-line args, specify the working directory and any environment variables.

There are other options there as well: code coverage, logging, build, JRE, etc.

Function:

function appendArray(form_data, values, name){
    if(!values && name)
        form_data.append(name, '');
    else{
        if(typeof values == 'object'){
            for(key in values){
                if(typeof values[key] == 'object')
                    appendArray(form_data, values[key], name + '[' + key + ']');
                else
                    form_data.append(name + '[' + key + ']', values[key]);
            }
        }else
            form_data.append(name, values);
    }

    return form_data;
}

Use:

var form = document.createElement('form');// or document.getElementById('my_form_id');
var formdata = new FormData(form);

appendArray(formdata, {
    sefgusyg: {
        sujyfgsujyfsg: 'srkisgfisfsgsrg',
    },
    test1: 5,
    test2: 6,
    test3: 8,
    test4: 3,
    test5: [
        'sejyfgjy',
        'isdyfgusygf',
    ],
});

I used the following code to listen to changes to an array.

/* @arr array you want to listen to
   @callback function that will be called on any change inside array
 */
function listenChangesinArray(arr,callback){
     // Add more methods here if you want to listen to them
    ['pop','push','reverse','shift','unshift','splice','sort'].forEach((m)=>{
        arr[m] = function(){
                     var res = Array.prototype[m].apply(arr, arguments);  // call normal behaviour
                     callback.apply(arr, arguments);  // finally call the callback supplied
                     return res;
                 }
    });
}

Hope this was useful :)

I just experienced the same behavior of tools:replace=... as described by the OP.

It turned out that the root cause for tools:replace being ignored by the manifest merger is a bug described here. It basically means that if you have a library in your project that contains a manifest with an <application ...> node containing a tools:ignore=... attribute, it can happen that the tools:replace=... attribute in the manifest of your main module will be ignored.

The tricky point here is that it can happen, but does not have to. In my case I had two libraries, library A with the tools:ignore=... attribute, library B with the attributes to be replaced in the respective manifests and the tools:replace=... attribute in the manifest of the main module. If the manifest of B was merged into the main manifest before the manifest of A everything worked as expected. In opposite merge order the error appeared.

The order in which these merges happen seems to be somewhat random. In my case changing the order in the dependencies section of build.gradle had no effect but changing the name of the flavor did it.

So, the only reliable workaround seems to be to unpack the problem causing library, remove the tools:ignore=... tag (which should be no problem as it is a hint for lint only) and pack the library again.

And vote for the bug to be fixed, of cause.

Bash does not support multidimensional arrays, nor hashes, and it seems that you want a hash that values are arrays. This solution is not very beautiful, a solution with an xml file should be better :

array=('d1=(v1 v2 v3)' 'd2=(v1 v2 v3)')
for elt in "${array[@]}";do eval $elt;done
echo "d1 ${#d1[@]} ${d1[@]}"
echo "d2 ${#d2[@]} ${d2[@]}"

EDIT: this answer is quite old, since since bash 4 supports hash tables, see also this answer for a solution without eval.

• First,in your celery APP:

vi my_celery_apps/app1.py

app = Celery(worker_name)

• and next, change to the task file,import app from your celery app module.

vi tasks/task1.py

from my_celery_apps.app1 import app

app.AsyncResult(taskid)

try:
   if task.state.lower() != "success":
        return
except:
    """ do something """

I was able to do this task efficiently by the following way

1. As soon as the button click handler is called disable the button

2. Do the necessary operations needed to be done.

3. Set the disabled property back to false after a couple of seconds using SetTimeout

    $('#btn1).click(function(e){
    $('#btn1').prop("disabled", true);
   
    setTimeout(()=>{
    $('#btn1').prop("disabled", false);
    },2000)
   

This should solve the issue.

If you have some 'condition' in your data to figure out the 254 ids, you could use:

delete from tablename
where id in 
(select id from tablename where <your-condition>)

or simply:

delete from tablename where <your-condition>

Simply hard coding the 254 values of id column would be very tough in any case.

i've got the following function in my "standard library"

/// Convert argument to an array.
function a($a = null) {
    if(is_null($a))
        return array();
    if(is_array($a))
        return $a;
    if(is_object($a))
        return (array) $a;
    return $_ = func_get_args();
}

Basically, this does nothing with arrays/objects and convert other types to arrays. This is extremely handy to use with foreach statements and array functions

  foreach(a($whatever) as $item)....

  $foo = array_map(a($array_or_string)....

  etc

Nowadays, Java 8 allows for a one-line functional solution that is cleaner, faster, and a whole lot simpler than the accepted solution:

List<String> list = new ArrayList<>();
list.add("behold");
list.add("bend");
list.add("bet");
list.add("bear");
list.add("beat");
list.add("become");
list.add("begin");

List<String> matches = list.stream().filter(it -> it.contains("bea")).collect(Collectors.toList());

System.out.println(matches); // [bear, beat]

And even easier in Kotlin:

val matches = list.filter { it.contains("bea") }

The best way to use is white-space: nowrap; This will align the text to one line.

Use extract(datetime) function it's so easy, simple.

It returns year, month, day, minute, second

Example:

select extract(year from sysdate) from dual;

add the activity in your manifest file

<activity android:name=".OrderScreen" />

Simply add a class name to the beginning of the funciton and the 2nd and 3rd arguments are optional and the magic is done for you!

function getElementsByClass(searchClass, node, tag) {

  var classElements = new Array();

  if (node == null)

    node = document;

  if (tag == null)

    tag = '*';

  var els = node.getElementsByTagName(tag);

  var elsLen = els.length;

  var pattern = new RegExp('(^|\\\\s)' + searchClass + '(\\\\s|$)');

  for (i = 0, j = 0; i < elsLen; i++) {

    if (pattern.test(els[i].className)) {

      classElements[j] = els[i];

      j++;

    }

  }

  return classElements;

}

The better option would be to just use the resource returned array as an array, meaning :

getResources().getStringArray(R.array.your_array)[position]

This is a shortcut approach of above mentioned approaches but does the work in the fashion you want. Otherwise android doesnt provides direct XML indexing for xml based arrays.

Here's an updated link.

There are updated now and then, just keep checking for the latest version.

Open the app/build.gradle file and check the property field compileSdkVersion in the android section. Change it to what you prefer.

If you have imported external libraries into your application (Ex: facebook), then make sure to check facebook/build.gradle also.

If any of other solution doesn't fix it, try to override the styles to hide the sort togglers:

.sorting_asc:after, .sorting_desc:after {
  content: "";
}

SELECT *
FROM BOOKING_SESSION
WHERE TO_CHAR(T_SESSION_DATETIME, 'DD-MM-YYYY') ='20-03-2012';

You don't need to convert to decimal; you can also enter 46 23S, 115 22E. You can add seconds after the minutes, also separated by a space.

The default timeout is defined by default_socket_timeout ini-setting, which is 60 seconds. You can also change it on the fly:

ini_set('default_socket_timeout', 900); // 900 Seconds = 15 Minutes

Another way to set a timeout, would be to use stream_context_create to set the timeout as HTTP context options of the HTTP stream wrapper in use:

$ctx = stream_context_create(array('http'=>
    array(
        'timeout' => 1200,  //1200 Seconds is 20 Minutes
    )
));

echo file_get_contents('http://example.com/', false, $ctx);

Late to the conversion...

For me, I found this at:

C:\Program Files (x86)\Android\android-sdk

This is the default location for Windows 64-bit.

Also, try to recall some of your default locations when not presented with some suggestions.

You always have to set the width and height of an Image. It is not going to automatically size things for you. The React Native docs says so.

You should measure the total height of the ScrollView using onLayout and set the height of the Images based on it. If you use resizeMode of cover it will keep the aspect ratio of your Images but it will obviously crop them if it's bigger than the container.

Yes, don't offset vertically or horizontally, and use a relatively large blur radius: fiddle

Also, you can use multiple box-shadows if you separate them with a comma. This will allow you to fine-tune where they blur and how much they extend. The example I provide is indistinguishable from a large outline, but it can be fine-tuned significantly more: fiddle

You missed the last and most relevant property of box-shadow, which is spread-distance. You can specify a value for how much the shadow expands or contracts (makes my second example obsolete): fiddle

The full property list is:

box-shadow: [horizontal-offset] [vertical-offset] [blur-radius] [spread-distance] [color] inset?

But even better, read through the spec.

Function inside function: we can use the function as parameter too..

In other words, we can say an output of a function is also a reference for an object, see below how the output of inner function is referencing to the outside function like below..

def out_func(a):

  def in_func(b):
       print(a + b + b + 3)
  return in_func

obj = out_func(1)
print(obj(5))

the result will be.. 14

Hope this helps.

MOVE /-Y Source Destination

Note:/-y will make the announcement of yes/no for overwrite

This is a "PHP Notice", so you could in theory ignore it. Change php.ini:

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED

To

error_reporting = E_ALL & ~E_NOTICE

This show all errors, except for notices.

A While/Wend loop can only be exited prematurely with a GOTO or by exiting from an outer block (Exit sub/function or another exitable loop)

Change to a Do loop instead:

Do While True
    count = count + 1

    If count = 10 Then
        Exit Do
    End If
Loop

Or for looping a set number of times:

for count = 1 to 10
   msgbox count
next

(Exit For can be used above to exit prematurely)

if your using php for the backend maybe you can use this code.

// Validate image file size
if (($_FILES["file-input"]["size"] > 2000000)) {
    $msg = "Image File Size is Greater than 2MB.";
    header("Location: ../product.php?error=$msg");
    exit();
}  

You could also just call the script from the terminal, outputting everything to a file, if that helps. This way:

$ /path/to/the/script.py > output.txt

This will overwrite the file. You can use >> to append to it.

If you want errors to be logged in the file as well, use &>> or &>.

Fall-through is really a handy thing, depending on what you're doing. Consider this neat and understandable way to arrange options:

switch ($someoption) {
  case 'a':
  case 'b':
  case 'c':
    // Do something
    break;

  case 'd':
  case 'e':
    // Do something else
    break;
}

Imagine doing this with if/else. It would be a mess.

simpler answer:

ax = plt.axes()
ax.set_facecolor('silver')

In latest IntelliJ versions, you should run it from Analyze->Run Inspection By Name:

Than, pick Unused declaration:

And finally, uncheck the Include test sources:

1. Undefined means a variable has been declared but it has not been assigned any value while Null can be assigned to a variable representing "no value".(Null is an assignment operator)

2.Undefined is a type itself while Null is an object.

3.Javascript can itself initialize any unassigned variable to undefined but it can never set value of a variable to null. This has to be done programatically.

No need to trying reinvent the wheel, as this is common greatest-n-per-group problem. Very nice solution is presented.

I prefer the most simplistic solution (see SQLFiddle, updated Justin's) without subqueries (thus easy to use in views):

SELECT t1.*
FROM lms_attendance AS t1
LEFT OUTER JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND (t1.time < t2.time 
         OR (t1.time = t2.time AND t1.Id < t2.Id))
WHERE t2.user IS NULL

This also works in a case where there are two different records with the same greatest value within the same group - thanks to the trick with (t1.time = t2.time AND t1.Id < t2.Id). All I am doing here is to assure that in case when two records of the same user have same time only one is chosen. Doesn't actually matter if the criteria is Id or something else - basically any criteria that is guaranteed to be unique would make the job here.

A much more robust way would be to use the getline() function of GNU awk to use a variable from a pipe. In form cmd | getline result, cmd is run, then its output is piped to getline. It returns 1 if got output, 0 if EOF, -1 on failure.

First construct the command to run in a variable in the BEGIN clause if the command is not dependant on the contents of the file, e.g. a simple date or an ls.

A simple example of the above would be

awk 'BEGIN {
    cmd = "ls -lrth"
    while ( ( cmd | getline result ) > 0 ) {
        print result
    }
    close(cmd);
}'

When the command to run is part of the columnar content of a file, you generate the cmd string in the main {..} as below. E.g. consider a file whose $2 contains the name of the file and you want it to be replaced with the md5sum hash content of the file. You can do

awk '{ cmd = "md5sum "$2
       while ( ( cmd | getline md5result ) > 0 ) { 
           $2 = md5result
       }
       close(cmd);
 }1'

Another frequent usage involving external commands in awk is during date processing when your awk does not support time functions out of the box with mktime(), strftime() functions.

Consider a case when you have Unix EPOCH timestamp stored in a column and you want to convert that to a human readable date format. Assuming GNU date is available

awk '{ cmd = "date -d @" $1 " +\"%d-%m-%Y %H:%M:%S\"" 
       while ( ( cmd | getline fmtDate) > 0 ) { 
           $1 = fmtDate
       }
       close(cmd);
}1' 

for an input string as

1572608319 foo bar zoo

the above command produces an output as

01-11-2019 07:38:39 foo bar zoo

The command can be tailored to modify the date fields on any of the columns in a given line. Note that -d is a GNU specific extension, the *BSD variants support -f ( though not exactly similar to -d).

More information about getline can be referred to from this AllAboutGetline article at awk.freeshell.org page.

If you want to close it you can either hide it or remove it from the page. To hide it you would do some javascript like:

this.parentNode.style.display = 'none';

To remove it you use removeChild

this.parentNode.parentNode.removeChild(this.parentNode);

If you had a library like jQuery included then hiding or removing the div would be slightly easier:

$(this).parent().hide();
$(this).parent().remove();

One other thing, as your img is in an anchor the onclick event on the anchor is going to fire as well. As the href is set to # then the page will scroll back to the top of the page. Generally it is good practice that if you want a link to do something other than go to its href you should set the onclick event to return false;

Most answers already cover getContext() and getApplicationContext() but getBaseContext() is rarely explained.

The method getBaseContext() is only relevant when you have a ContextWrapper. Android provides a ContextWrapper class that is created around an existing Context using:

ContextWrapper wrapper = new ContextWrapper(context);

The benefit of using a ContextWrapper is that it lets you “modify behavior without changing the original Context”. For example, if you have an activity called myActivity then can create a View with a different theme than myActivity:

ContextWrapper customTheme = new ContextWrapper(myActivity) {
  @Override
  public Resources.Theme getTheme() { 
    return someTheme;
  }
}
View myView = new MyView(customTheme);

ContextWrapper is really powerful because it lets you override most functions provided by Context including code to access resources (e.g. openFileInput(), getString()), interact with other components (e.g. sendBroadcast(), registerReceiver()), requests permissions (e.g. checkCallingOrSelfPermission()) and resolving file system locations (e.g. getFilesDir()). ContextWrapper is really useful to work around device/version specific problems or to apply one-off customizations to components such as Views that require a context.

The method getBaseContext() can be used to access the “base” Context that the ContextWrapper wraps around. You might need to access the “base” context if you need to, for example, check whether it’s a Service, Activity or Application:

public class CustomToast {
  public void makeText(Context context, int resId, int duration) {
    while (context instanceof ContextWrapper) {
      context = context.baseContext();
    }
    if (context instanceof Service)) {
      throw new RuntimeException("Cannot call this from a service");
    }
    ...
  }
}

Or if you need to call the “unwrapped” version of a method:

class MyCustomWrapper extends ContextWrapper {
  @Override
  public Drawable getWallpaper() {
    if (BuildInfo.DEBUG) {
      return mDebugBackground;
    } else {
      return getBaseContext().getWallpaper();
    }
  }
}

I can't see pass-by-reference in the examples where people try to demonstrate such. I only see pass-by-value.

In the case of variables that hold a reference to an object, the reference is the value of those variables, and therefore the reference is passed, which is then pass-by-value.

In a statement like this,

var a = {
  b: "foo",
  c: "bar"
};

the value of the 'a' is not the Object, but the (so far only) reference to it. In other words, the object is not in the variable a - a reference to it is. I think this is something that seems difficult for programmers who are mainly only familiar with JavaScript. But it is easy for people who know also e.g. Java, C#, and C.

This didn't work for me, as it went too far up the tree, and got the absolute root window for the entire application:

Window parentWindow = Window.GetWindow(userControlReference);

However, this worked to get the immediate window:

DependencyObject parent = uiElement;
int avoidInfiniteLoop = 0;
while ((parent is Window)==false)
{
    parent = VisualTreeHelper.GetParent(parent);
    avoidInfiniteLoop++;
    if (avoidInfiniteLoop == 1000)
    {
        // Something is wrong - we could not find the parent window.
        break;
    }
}
Window window = parent as Window;
window.DragMove();

For website developers, another option you have is to follow a working Facebook Graph API tutorial such as this one.

But if you need a quick solution where you can customize and embed a Facebook page feed instantly, you should use website plugins such as this one.

Here's a step by step guide:

1. Get a Free Key or Paid Key.
2. Go to this login page and use the key to login.
3. Once logged in, click “+ Create Custom Feed” button.
4. On the pop up, name your custom Facebook page feed.
5. On the drop-down, select “Facebook Page Feed On Your Website” option.
6. Enter your Facebook Page ID.
7. Click the “Proceed” button. This will show you the customization options.
8. Click the “ Embed On Website” button located on the upper-right corner of the screen.
9. On the pop up, copy the embed code by clicking the “Copy Code” button.
10. Paste the embed code on your website.

Visit the tutorial link to see a live demo there as well.

 <GridViewName>.ClearSelection(); ----------------------------------------------------1
 foreach(var item in itemList) -------------------------------------------------------2
 {
    rowHandle =<GridViewName>.LocateByValue("UniqueProperty_Name", item.unique_id );--3
    if (rowHandle != GridControl.InvalidRowHandle)------------------------------------4
    {
        <GridViewName>.SelectRow(rowHandle);------------------------------------ -----5
    }
  }

1. Clear all previous selection.
2. Loop through rows needed to be selected in your grid.
3. Get their row handles from grid (Note here grid is already updated with new rows)
4. Checking if the row handle is valid or not.
5. When valid row handle then select it.

Where itemList is list of rows to be selected in the grid view.

You could overlay one element above the blurred element like so

DEMO

div {
    position: absolute;
    left:0;
    top: 0;
}
p {
    position: absolute;
    left:0;
    top: 0;
}

Following solution can be pretty useful in the usual login / main activity scenario or implementing a blocking screen.

To minimize the app rather than going back to previous activity, you can override onBackPressed() like this:

@Override
public void onBackPressed() {
    moveTaskToBack(true);
}

moveTaskToBack(boolean nonRoot) leaves your back stack as it is, just puts your task (all activities) in background. Same as if user pressed Home button.

Parameter boolean nonRoot - If false then this only works if the activity is the root of a task; if true it will work for any activity in a task.

If that's all what you want to do, you don't need to convert it into an array. You can just access it as:

string myData=yourDataTable.Rows[0][1].ToString();//Gives you USA

In:

for i in range(c/10):

You're creating a float as a result - to fix this use the int division operator:

for i in range(c // 10):

java.util.Date utilDate = new java.util.Date();
java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());
System.out.println("utilDate:" + utilDate);
System.out.println("sqlDate:" + sqlDate);

This gives me the following output:

 utilDate:Fri Apr 04 12:07:37 MSK 2014
 sqlDate:2014-04-04

Among other things that can cause this error:

You cannot have certain characters in the full PathFile string.

For example, these characters will crash the StreamWriter function:

"/"  
":"

there may be other special characters that crash it too. I found this happens when you try, for example, to put a DateTime stamp into a filename:

AppPath = Path.GetDirectoryName(giFileNames(0))  
' AppPath is a valid path from system. (This was easy in VB6, just AppPath = App.Path & "\")
' AppPath must have "\" char at the end...

DateTime = DateAndTime.Now.ToString ' fails StreamWriter... has ":" characters
FileOut = "Data_Summary_" & DateTime & ".dat"
NewFileOutS = Path.Combine(AppPath, FileOut)
Using sw As StreamWriter = New StreamWriter(NewFileOutS  , True) ' true to append
        sw.WriteLine(NewFileOutS)
        sw.Dispose()
    End Using

One way to prevent this trouble is to replace problem characters in NewFileOutS with benign ones:

' clean the File output file string NewFileOutS so StreamWriter will work
 NewFileOutS = NewFileOutS.Replace("/","-") ' replace / with -
 NewFileOutS = NewFileOutS.Replace(":","-") ' replace : with - 

' after cleaning the FileNamePath string NewFileOutS, StreamWriter will not throw an (Unhandled) exception.

Hope this saves someone some headaches...!

public static void ToPrintConsole(this DataTable dataTable)
    {
        // Print top line
        Console.WriteLine(new string('-', 75));

        // Print col headers
        var colHeaders = dataTable.Columns.Cast<DataColumn>().Select(arg => arg.ColumnName);
        foreach (String s in colHeaders)
        {
            Console.Write("| {0,-20}", s);
        }
        Console.WriteLine();

        // Print line below col headers
        Console.WriteLine(new string('-', 75));

        // Print rows
        foreach (DataRow row in dataTable.Rows)
        {
            foreach (Object o in row.ItemArray)
            {
                Console.Write("| {0,-20}", o.ToString());
            }
            Console.WriteLine();
        }

        // Print bottom line
        Console.WriteLine(new string('-', 75));
    }

Don't use a service for this. Create a normal application and create a scheduled task to run it.

This is the commonly held best practice. Jon Galloway agrees with me. Or maybe its the other way around. Either way, the fact is that it is not best practices to create a windows service to perform an intermittent task run off a timer.

As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)

Duration column = End - Start

1. Once done, plot your stacked bar chart using the entire data.
2. Mark start and end range to no fill.
3. Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))

you can use row() instead of result().

$this->db->where('id', '3');
$q = $this->db->get('my_users_table')->row();

You can get this if the client specifies "https" but the server is only running "http". So, the server isn't expecting to make a secure connection.

From the offical docs: (http://api.jquery.com/hover/)

The .hover() method binds handlers for both mouseenter and mouseleave events. You can use it to simply apply behavior to an element during the time the mouse is within the element.

var obj = new Dictionary<string, object>;
...
Console.WriteLine(obj["MyString"]);

I think that only works because everything has a ToString(), otherwise you'd have to know the type that it was and cast the 'object' to that type.

Some of these are useful more often than others, I'm trying to be thorough.

1. It may be far more natural to access a collection, in this case what is effectively a "dictionary", using the more direct dot notation.

2. It seems as if this could be used as a really nice Tuple. You can still call your members "Item1", "Item2" etc... but now you don't have to, it's also mutable, unlike a Tuple. This does have the huge drawback of lack of intellisense support.

3. You may be uncomfortable with "member names as strings", as is the feel with the dictionary, you may feel it is too like "executing strings", and it may lead to naming conventions getting coded in, and dealing with working with morphemes and syllables when code is trying understand how to use members :-P

4. Can you assign a value to an ExpandoObject itself or just it's members? Compare and contrast with dynamic/dynamic[], use whichever best suits your needs.

5. I don't think dynamic/dynamic[] works in a foreach loop, you have to use var, but possibly you can use ExpandoObject.

6. You cannot use dynamic as a data member in a class, perhaps because it's at least sort of like a keyword, hopefully you can with ExpandoObject.

7. I expect it "is" an ExpandoObject, might be useful to label very generic things apart, with code that differentiates based on types where there is lots of dynamic stuff being used.

Be nice if you could drill down multiple levels at once.

var e = new ExpandoObject();
e.position.x = 5;
etc...

Thats not the best possible example, imagine elegant uses as appropriate in your own projects.

It's a shame you cannot have code build some of these and push the results to intellisense. I'm not sure how this would work though.

Be nice if they could have a value as well as members.

var fifteen = new ExpandoObject();
fifteen = 15;
fifteen.tens = 1;
fifteen.units = 5;
fifteen.ToString() = "fifteen";
etc...

def magic(numbers):
    return int(''.join([ "%d"%x for x in numbers]))

Error "res://ieframe.dll/acr_error.htm#"

In my case, cannot open some websites or after openned IE8 gave "cannot return to website error". After some visits to MS help sites like this and followed all the instructioms with no avail I saw what seems to me a tip.

In one of the MS websites they say to delete old Java versions using "control panel" and "add remove programs". I did just that but only saw one version of Java v.6u22. Then I got the idea of download the last version of Java from some days ago v.6u29 and voila... IE8 is working now and seems OK. I'm writing this in the hope this can help others.

I was using an older version of Nuget on VS2010, where it defaults to TLS 1.0 here it can be fixed by changing the default TLS version used by .Net framework which is configured in Registry keys

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f /reg:64

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f /reg:32

FYI

NuGet.org will permanently remove support for TLS 1.0 and 1.1 on June 15th. Please ensure that your systems use TLS 1.2.

You can refer to this link for info on TLS 1.2 support

The correct form, based on the original syntax, and correctly normalized is:

def gaussian(x, mu, sig):
    return 1./(np.sqrt(2.*np.pi)*sig)*np.exp(-np.power((x - mu)/sig, 2.)/2)

Absent a really good reason to do otherwise, I'd probably use:

std::vector<char> msg(65546, '\0');

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

Try this:

$ git apply file.diff

Shelving has many uses. The main ones are:

1. Context Switching: Saving the work on your current task so you can switch to another high priority task. Say you're working on a new feature, minding your own business, when your boss runs in and says "Ahhh! Bug Bug Bug!" and you have to drop your current changes on the feature and go fix the bug. You can shelve your work on the feature, fix the bug, then come back and unshelve to work on your changes later.
2. Sharing Changesets: If you want to share a changeset of code without checking it in, you can make it easy for others to access by shelving it. This could be used when you are passing an incomplete task to someone else (poor soul) or if you have some sort of testing code you would never EVER check in that someone else needed to run. h/t to the other responses about using this for reviews, it is a very good idea.
3. Saving your progress: While you're working on a complex feature, you may find yourself at a 'good point' where you would like to save your progress. This is an ideal time to shelve your code. Say you are hacking up some CSS / HTML to fix rendering bugs. Usually you bang on it, iterating every possible kludge you can think up until it looks right. However, once it looks right you may want to try and go back in to cleanup your markup so that someone else may be able to understand what you did before you check it in. In this case, you can shelve the code when everything renders right, then you are free to go and refactor your markup, knowing that if you accidentally break it again, you can always go back and get your changeset.

Any other uses?

We do it that way: First add this script.

<script type="text/javascript">
function populateIframe(id,path) 
{
    var ifrm = document.getElementById(id);
    ifrm.src = "download.php?path="+path;
}
</script>

Place this where you want the download button(here we use just a link):

<iframe id="frame1" style="display:none"></iframe>
<a href="javascript:populateIframe('frame1','<?php echo $path; ?>')">download</a>

The file 'download.php' (needs to be put on your server) simply contains:

<?php 
   header("Content-Type: application/octet-stream");
   header("Content-Disposition: attachment; filename=".$_GET['path']);
   readfile($_GET['path']);
?>

So when you click the link, the hidden iframe then gets/opens the sourcefile 'download.php'. With the path as get parameter. We think this is the best solution!

It should be noted that the PHP part of this solution is a simple demonstration and potentially very, very insecure. It allows the user to download any file, not just a pre-defined set. That means they could download parts of the source code of the site itself, possibly containing API credentials etc.

You can simply add DISTINCT in front.

SELECT GROUP_CONCAT(DISTINCT categories SEPARATOR ' ')

if you want to sort,

SELECT GROUP_CONCAT(DISTINCT categories ORDER BY categories ASC SEPARATOR ' ')

Try this:

style="margin: auto"

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

Regarding to OOP, the answer is too simple:

The subclasses can override class methods, but cannot override static methods.

In addition to your post, if you want to declare a class variable (like you did class var myVar2 = ""), you should do it as follow:

class var myVar2: String {
    return "whatever you want"
}

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

you use renameTo() – not obvious, I know ... but it's the Java equivalent of move ...

You can use the str.split method: string.split('__')

>>> "MATCHES__STRING".split("__")
['MATCHES', 'STRING']

None of the above worked for me.

This happened to me after I added a new button to a toolstrip on a winform. When the button uses the default image of System.Drawing.Bitmap (in image property) this error arose for me. After I changed it to a trusted image (one added to my resource file with 'Unlock' option checked) this error resolved itself.

I discovered that I was also having this error in NetBeans. I hope the following is helpful.

1. Make sure that when you go to Project Configuration you set the main class you intend for running.
2. Do a Build or Clean Build
3. Place the jar file where you wish and try: java -jar "YourProject.jar" again at the command line.

This was the problem I was getting because I had other "test" programs I was using in NetBeans and I had to make sure the Main Class under the Run portion of the Project configuration was set correctly.

many blessings, John P

Simple Explanation via analogy

Synchronous Execution

My boss is a busy man. He tells me to write the code. I tell him: Fine. I get started and he's watching me like a vulture, standing behind me, off my shoulder. I'm like "Dude, WTF: why don't you go and do something while I finish this?"

he's like: "No, I'm waiting right here until you finish." This is synchronous.

Asynchronous Execution

The boss tells me to do it, and rather than waiting right there for my work, the boss goes off and does other tasks. When I finish my job I simply report to my boss and say: "I'm DONE!" This is Asynchronous Execution.

(Take my advice: NEVER work with the boss behind you.)

HTML 5 does support iframes. There were a few interesting attributes added like "sandbox" and "srcdoc".

http://www.w3schools.com/html5/tag_iframe.asp

or you can use

<object data="framed.html" type="text/html"><p>This is the fallback code!</p></object>

You can directly plot the lines you want by feeding the plot command with the corresponding data (boundaries of the segments):

plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)

(of course you can choose the color, line width, line style, etc.)

From your example:

import numpy as np
import matplotlib.pyplot as plt

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")


# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)

# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')

plt.show()

You can also use starts_with and dplyr's select() like so:

df <- df %>% dplyr:: select(starts_with("ABC"))

For the line

line.split()

What are you splitting on? Looks like a CSV, so try

line.split(',')

Example:

"one,two,three".split()  # returns one element ["one,two,three"]
"one,two,three".split(',')  # returns three elements ["one", "two", "three"]

As @TigerhawkT3 mentions, it would be better to use the CSV module. Incredibly quick and easy method available here.

If you know the items you are mapping through, you can accomplish this by doing one row at a time. I know it's a workaround, but it works.

For me I had 4 items per row, so I broke it up into two rows of 4 with each row height: 50%, get rid of flex-grow, have <RowOne /> and <RowTwo /> in a <div> with flex-column. This will do the trick

<div class='flexbox flex-column height-100-percent'>
   <RowOne class='flex height-50-percent' />
   <RowTwo class='flex height-50-percent' />
</div>

If your objects has some common ancestor [let it be T] you should use List<T> instead of List<Object>, and implement a Comparator for this T, using the name field.

If you don't have a common ancestor, you can implement a Comperator, and use reflection to extract the name, Note that it is unsafe, unsuggested, and suffers from bad performance to use reflection, but it allows you to access a field name without knowing anything about the actual type of the object [besides the fact that it has a field with the relevant name]

In both cases, you should use Collections.sort() to sort.

The approach you're looking for is FillDown. Another way so you don't have to kick your head off every time is to store formulas in an array of strings. Combining them gives you a powerful method of inputting formulas by the multitude. Code follows:

Sub FillDown()

    Dim strFormulas(1 To 3) As Variant

    With ThisWorkbook.Sheets("Sheet1")
        strFormulas(1) = "=SUM(A2:B2)"
        strFormulas(2) = "=PRODUCT(A2:B2)"
        strFormulas(3) = "=A2/B2"

        .Range("C2:E2").Formula = strFormulas
        .Range("C2:E11").FillDown
    End With

End Sub

Screenshots:

Result as of line: .Range("C2:E2").Formula = strFormulas:

Result as of line: .Range("C2:E11").FillDown:

Of course, you can make it dynamic by storing the last row into a variable and turning it to something like .Range("C2:E" & LRow).FillDown, much like what you did.

Hope this helps!

There is at least one middleware on npm for handling CORS in Express: cors.

If you are doing this on mac type: sudo chown -R $USER /usr/local that will give you administrative access to your files

Updated for modern versions of .NET per @1c1cle's suggestion in a comment:

<%= Html.TextBoxFor(model => Model.SomeFieldName, new {{"readonly", "true"}}) %>

Do realize that this is not a "secure" way to do this as somebody can inject javascript to change this.

Something to be aware of is that if you set that readonly value to false, you actually won't see any change in behavior! So if you need to drive this based on a variable, you cannot simply plug that variable in there. Instead you need to use conditional logic to simply not pass that readonly attribute in.

Here is an untested suggestion for how to do this (if there's a problem with this, you can always do an if/else):

<%= Html.TextBoxFor(model => Model.SomeFieldName, shouldBeReadOnlyBoolean ? new {{"readonly", "true"}} : null) %>

Generally speaking, 5xx response codes indicate non-programmatic failures, such as a database connection failure, or some other system/library dependency failure. In many cases, it is expected that the client can re-submit the same request in the future and expect it to be successful.

Yes, some web-frameworks will respond with 5xx codes, but those are typically the result of defects in the code and the framework is too abstract to know what happened, so it defaults to this type of response; that example, however, doesn't mean that we should be in the habit of returning 5xx codes as the result of programmatic behavior that is unrelated to out of process systems. There are many, well defined response codes that are more suitable than the 5xx codes. Being unable to parse/validate a given input is not a 5xx response because the code can accommodate a more suitable response that won't leave the client thinking that they can resubmit the same request, when in fact, they can not.

To be clear, if the error encountered by the server was due to CLIENT input, then this is clearly a CLIENT error and should be handled with a 4xx response code. The expectation is that the client will correct the error in their request and resubmit.

It is completely acceptable, however, to catch any out of process errors and interpret them as a 5xx response, but be aware that you should also include further information in the response to indicate exactly what failed; and even better if you can include SLA times to address.

I don't think it's a good practice to interpret, "an unexpected error" as a 5xx error because bugs happen.

It is a common alert monitor to begin alerting on 5xx types of errors because these typically indicate failed systems, rather than failed code. So, code accordingly!

All you should need to do is:

# if the file in the right place isn't already committed:
git add <path to desired file>

# remove the "both deleted" file from the index:
git rm --cached ../public/images/originals/dog.ai

# commit the merge:

There exist breakpoint() method nowadays, which replaces import pdb; pdb.set_trace().

It also has several new features, such as possible environment variables.

Mine were located here on Ubuntu 18.04 when I installed JavaFX using apt install openjfx (as noted already by @jewelsea above)

/usr/share/java/openjfx/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar

You could manipulate the image itself, but a much better way is to simply add a UIView that contains the UIImageView, and change the background to black. Then set the size of that container view to a little bit larger than the UIImageView.

There are two ways to resolve this issue.Try option 1 first, if it doesn't work try option 2, and your problem is solved.

1) On the top right corner of your console, there is a red button, to stop the spring boot application which is already running on this port just click on the red button to terminate.

2) If the red button is not activated you need to right click on the console and select terminate/disconnect all. Hope this helps.

Bonus tip:- If you want to run your server on a different port of your choice, create a file named application.properties in resource folder of your maven project and write server.port=3000 to run your application on port 3000

Since .Net 4.6 and above please use DateTimeOffset.Now.ToUnixTimeSeconds()

<a href="#"><button type="button" class="btn btn-info btn-block regular-link"> <span class="text">Create New Board</span></button></a>

We can use btn-block for automatic responsive.

Note that if you're expecting 100K users per day, that are active for hours at a time (meaning max of 20K+ concurrent users), you're going to need A LOT of servers. SO has ~15,000 registered users, and most of them are probably not active daily. While the bulk of traffic comes from unregistered users, I'm guessing that very few of them stay on the site more than a couple minutes (i.e. they follow google search results then leave).

For that volume, expect at least 30 servers ... which is still a rather heavy 1,000 concurrent users per server.

Check with following css. Demo

.circle { 
   width: 140px;
   height: 140px;
   background: red; 
   -moz-border-radius: 70px; 
   -webkit-border-radius: 70px; 
   border-radius: 70px;
}

For more shapes you can follow following urls:

Have you tried to add the "s" on: w.writerow(mydict) like this: w.writerows(mydict)? This issue happened to me but with lists, I was using singular instead of plural.

This is the solution if your file has more . (dots) in the name.

<script type="text/javascript">var x = "file1.asdf.txt";
var y = x.split(".");
alert(y[(y.length)-1]);</script>

You can useflatten() from the numpy package.

import numpy as np
a = np.array([[1, 2],
       [3, 4],
       [5, 6]])
a_flat = a.flatten()
print(f"original array: {a} \nflattened array = {a_flat}")

Output:

original array: [[1 2]
 [3 4]
 [5 6]] 
flattened array = [1 2 3 4 5 6]

In Bash:

printf "%q" "hello\world" | someprog

for example:

printf "%q" "hello\world"
hello\\world

This could be used through variables too:

printf -v var "%q\n" "hello\world"
echo "$var"
hello\\world

A simple way is to tell IIS to send your custom error file for HTTP requests. The file can then contain a meta redirect, a JavaScript redirect and instructions with link, etc... Importantly, you can still check "Require SSL" for the site (or folder) and this will work.

</configuration>
</system.webServer>
    <httpErrors>
        <clear/>
        <!--redirect if connected without SSL-->
        <error statusCode="403" subStatusCode="4" path="errors\403.4_requiressl.html" responseMode="File"/>
    </httpErrors>
</system.webServer>
</configuration>

I must bring an amazing tool to your notice which i have used sometime back. AVICode Interceptor Studio. In my previous company we used this wonderful tool to profile the webapplication (This is supposed to be the single largest web application in the world and the largest civilian IT project ever done). The performance team did wonders with the help of this magnificent tool. It is a pain to configure it, but that is a one time activity and i would say it is worth the time. Checkout this page for details.

Simple Solution :

Open Android SDK manager, on top side you can see the "Android SDK Location" go to that location and follow this path

\extras\intel\Hardware_Accelerated_Execution_Manager

here you will get "intelhaxm-android.exe" install this setup.

Minizip does have an example programs to demonstrate its usage - the files are called minizip.c and miniunz.c.

Update: I had a few minutes so I whipped up this quick, bare bones example for you. It's very smelly C, and I wouldn't use it without major improvements. Hopefully it's enough to get you going for now.

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

There is a simple way:

Android:

   String macAddress = 
android.provider.Settings.Secure.getString(this.getApplicationContext().getContentResolver(), "android_id");

Xamarin:

    Settings.Secure.GetString(this.ContentResolver, "android_id");

The jQuery documentation provides a detailed explanation for checked property vs attribute.

Accordingly, here is another way to retrieve selected radio button value

var accepted = $('input[name="Contact0_AmericanExpress"]:checked').val();

The property 'length' returns the (last_key + 1) for arrays with numeric keys:

var  nums  =  new  Array ();
nums [ 10 ]  =  10 ; 
nums [ 11 ]  =  11 ;
log.info( nums.length );

will print 12!

This will work:

var  nums  =  new  Array ();
nums [ 10 ]  =  10 ; 
nums [ 11 ]  =  11 ;
nums [ 12 ]  =  12 ;
log.info( nums.length + '  /  '+ Object.keys(nums).length );

For me the bold work when I change the font style from font-family: 'Open Sans', sans-serif; to Arial

Try this way:

I have a package named plant_seedlings. The package is stored in google drive. What I should do is to copy this package in /usr/local/lib/python3.6/dist-packages/.

!cp /content/drive/ai/plant_seedlings.tar.gz /usr/local/lib/python3.6/dist-packages/

!cd /usr/local/lib/python3.6/dist-packages/ && tar -xzf plant_seedlings.tar.gz

!cd /content

!python -m plant_seedlings

I think you mean to put the rolling of the random a,b,c, etc within the loop:

a = None # initialise
while not (a in winning_numbers):
    # keep rolling an a until you get one not in winning_numbers
    a = random.randint(1,30)
    winning_numbers.append(a)

Otherwise, a will be generated just once, and if it is in winning_numbers already, it won't be added. Since the generation of a is outside the while (in your code), if a is already in winning_numbers then too bad, it won't be re-rolled, and you'll have one less winning number.

That could be what causes your error in if guess[i] == winning_numbers[i]. (Your winning_numbers isn't always of length 5).

This function do the truncate space and words parts also.(ex: Mother into Moth...)

String.prototype.truc= function (length) {
        return this.length>length ? this.substring(0, length) + '…' : this;
};

usage:

"this is long length text".trunc(10);
"1234567890".trunc(5);

output:

this is lo...

12345...

To conditionally check the length of the string, use CASE.

SELECT  CASE WHEN LEN(comments) <= 60 
             THEN comments
             ELSE LEFT(comments, 60) + '...'
        END  As Comments
FROM    myView

While verbatim might be the best choice, you can also try the commands \smallskip , \medskip or guess what, \bigskip .

Quoting from this page:

These commands can only be used after a paragraph break (which is made by one completely blank line or by the command \par). These commands output flexible or rubber space, approximately 3pt, 6pt, and 12pt high respectively, but these commands will automatically compress or expand a bit, depending on the demands of the rest of the page

Here is a working solution:

Instead of setting the spinner's OnClickListener, we are setting OnTouchListener and OnKeyListener.

spinner.setOnTouchListener(Spinner_OnTouch);
spinner.setOnKeyListener(Spinner_OnKey);

and the listeners:

private View.OnTouchListener Spinner_OnTouch = new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatYouWantHere();
        }
        return true;
    }
};
private static View.OnKeyListener Spinner_OnKey = new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
            doWhatYouWantHere();
            return true;
        } else {
            return false;
        }
    }
};

You can add parameter columns or use dict with key which is converted to column name:

np.random.seed(123)
e = np.random.normal(size=10)  
dataframe=pd.DataFrame(e, columns=['a']) 
print (dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

e_dataframe=pd.DataFrame({'a':e}) 
print (e_dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

I agree with Ben. You cannot load/import the simple JSON file.

But if you absolutely want to do that and have flexibility to update json file, you can

my-json.js

   var myJSON = {
      id: "12ws",
      name: "smith"
    }

index.html

<head>
  <script src="my-json.js"></script>
</head>
<body onload="document.getElementById('json-holder').innerHTML = JSON.stringify(myJSON);">
  <div id="json-holder"></div>
</body>

Easiest is by using FileUtils from Apache commons-io.( https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/FileUtils.html )

Returns human readable file size from Bytes to Exabytes , rounding down to the boundary.

File fileObj = new File(filePathString);
String fileSizeReadable = FileUtils.byteCountToDisplaySize(fileObj.length());

// output will be like 56 MB 

I wrestled with this for some time. It became a huge pain to simply get to my local sqlite db. I wrote this script and made it a code snippet inside XCode. I place it inside my appDidFinishLaunching inside my appDelegate.

//xcode 6 moves the documents dir every time. haven't found out why yet. 

    #if DEBUG 

         NSLog(@"caching documents dir for xcode 6. %@", [NSBundle mainBundle]); 

         NSString *toFile = @"XCodePaths/lastBuild.txt"; NSError *err = nil; 

         [DOCS_DIR writeToFile:toFile atomically:YES encoding:NSUTF8StringEncoding error:&err]; 

         if(err) 
            NSLog(@"%@", [err localizedDescription]);

         NSString *appName = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleName"];   

         NSString *aliasPath = [NSString stringWithFormat:@"XCodePaths/%@", appName]; 

         remove([aliasPath UTF8String]); 

         [[NSFileManager defaultManager] createSymbolicLinkAtPath:aliasPath withDestinationPath:DOCS_DIR error:nil]; 

     #endif

This creates a simlink at the root of your drive. (You might have to create this folder yourself the first time, and chmod it, or you can change the location to some other place) Then I installed the xcodeway plugin https://github.com/onmyway133/XcodeWay

I modified it a bit so that it will allow me to simply press cmd+d and it will open a finder winder to my current application's persistent Documents directory. This way, not matter how many times XCode changes your path, it only changes on run, and it updates your simlink immediately on each run.

I hope this is useful for others!

I modified @Alisa's code and used cProfile to show why list comprehension is faster:

from functools import reduce
import datetime

def reduce_(numbers):
    return reduce(lambda sum, next: sum + next * next, numbers, 0)

def for_loop(numbers):
    a = []
    for i in numbers:
        a.append(i*2)
    a = sum(a)
    return a

def map_(numbers):
    sqrt = lambda x: x*x
    return sum(map(sqrt, numbers))

def list_comp(numbers):
    return(sum([i*i for i in numbers]))

funcs = [
        reduce_,
        for_loop,
        map_,
        list_comp
        ]

if __name__ == "__main__":
    # [1, 2, 5, 3, 1, 2, 5, 3]
    import cProfile
    for f in funcs:
        print('=' * 25)
        print("Profiling:", f.__name__)
        print('=' * 25)
        pr = cProfile.Profile()
        for i in range(10**6):
            pr.runcall(f, [1, 2, 5, 3, 1, 2, 5, 3])
        pr.create_stats()
        pr.print_stats()

IMHO:

• reduce and map are in general pretty slow. Not only that, using sum on the iterators that map returned is slow, compared to suming a list
• for_loop uses append, which is of course slow to some extent
• list-comprehension not only spent the least time building the list, it also makes sum much quicker, in contrast to map

Even when the question is regarding Java 7, I think it adds value to know that from Java 11 onward, there is a static method in Path class that allows to do this straight away:

With all the path in one String:

Path.of("/tmp/foo");

With the path broken down in several Strings:

Path.of("/tmp","foo");

This first choice might be a confusing one but it’s really very simple. PhoneGap is a product owned by Adobe which currently includes additional build services, and it may or may not eventually offer additional services and/or charge payments for use in the future. Cordova is owned and maintained by Apache, and will always be maintained as an open source project. Currently they both have a very similar API. I would recommend going with Cordova, unless you require the additional PhoneGap build services.

None of the answers worked for me because all my HTML was in a single line.

Basically you need first to break each line with the following command that substitutes >< with the same characters but with a line break in the middle.

:%s/></>\r</g

Then the command

gg=G

will indent the file.

You can open the file again using vi helloworld.txt and then use cat /path/your_file to view it.

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

If you are using the GUI to do this you must deselect the following option allowing the table to be dropped,

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

import os 
zip_file_path = "C:\AA\BB"
file_list = os.listdir(path)
abs_path = []
for a in file_list:
    x = zip_file_path+'\\'+a
    print x
    abs_path.append(x)
for f in abs_path:
    zip=zipfile.ZipFile(f)
    zip.extractall(zip_file_path)

This does not contain validation for the file if its not zip. If the folder contains non .zip file it will fail.

Using reshape package:

#data
x <- read.table(textConnection(
"Code Country        1950    1951    1952    1953    1954
AFG  Afghanistan    20,249  21,352  22,532  23,557  24,555
ALB  Albania        8,097   8,986   10,058  11,123  12,246"), header=TRUE)

library(reshape)

x2 <- melt(x, id = c("Code", "Country"), variable_name = "Year")
x2[,"Year"] <- as.numeric(gsub("X", "" , x2[,"Year"]))

I've tried the other answers listed above, but they are very far from decent solutions when dealing with large files -- especially once a single line's size occupies more than ~1/4 of available RAM.

Both bash and awk slurp the entire line, even though for this problem it's not needed. Bash will error out once a line is too long, even if you have enough memory.

I've implemented an extremely simple, fairly unoptimized python script that when tested with large files (~4 GB per line) doesn't slurp, and is by far a better solution than those given.

If this is time critical code for production, you can rewrite the ideas in C or perform better optimizations on the read call (instead of only reading a single byte at a time), after testing that this is indeed a bottleneck.

Code assumes newline is a linefeed character, which is a good assumption for Unix, but YMMV on Mac OS/Windows. Be sure the file ends with a linefeed to ensure the last line character count isn't overlooked.

from sys import stdin, exit

counter = 0
while True:
    byte = stdin.buffer.read(1)
    counter += 1
    if not byte:
        exit()
    if byte == b'\x0a':
        print(counter-1)
        counter = 0

You can sort by values in reverse order (largest to smallest) using a dictionary comprehension:

{k: d[k] for k in sorted(d, key=d.get, reverse=True)}
# {'b': 4, 'a': 3, 'c': 2, 'd': 1}

If you want to sort by values in ascending order (smallest to largest)

{k: d[k] for k in sorted(d, key=d.get)}
# {'d': 1, 'c': 2, 'a': 3, 'b': 4}

If you want to sort by the keys in ascending order

{k: d[k] for k in sorted(d)}
# {'a': 3, 'b': 4, 'c': 2, 'd': 1}

This works on CPython 3.6+ and any implementation of Python 3.7+ because dictionaries keep insertion order.

The Python package drawnow allows to update a plot in real time in a non blocking way.
It also works with a webcam and OpenCV for example to plot measures for each frame.

One can also use nvtop, which gives an interface very similar to htop, but showing your GPU(s) usage instead, with a nice graph. You can also kill processes directly from here.

Use the Unicode Character 'BLACK CIRCLE' (U+25CF) http://www.fileformat.info/info/unicode/char/25CF/index.htm

To copy and paste: ?

DECLARE @baseTicks AS BIGINT;
SET @baseTicks = 599266080000000000; --# ticks up to 1900-01-01

DECLARE @ticksPerDay AS BIGINT;
SET @ticksPerDay = 864000000000;

SELECT CAST(@baseTicks + (@ticksPerDay * CAST(GETDATE() AS FLOAT)) AS BIGINT) AS currentDateTicks;

If you're doing this in the context of a asp.Net Core API action, the conversion to Json is done implicitly.

[HttpGet]
public ActionResult Get()
{
    return Ok(TheList);
}

There is a difference.

When the ^ character appears outside of [] matches the beginning of the line (or string). When the ^ character appears inside the [], it matches any character not appearing inside the [].

What you're doing is correct. Fragments don't have access to the ActionBar APIs, so you have to call getActivity. Unless your Fragment is a static inner class, in which case you should create a WeakReference to the parent and call Activity.getActionBar from there.

To set the title for your ActionBar, while using a custom layout, in your Fragment you'll need to call getActivity().setTitle(YOUR_TITLE).

The reason you call setTitle is because you're calling getTitle as the title of your ActionBar. getTitle returns the title for that Activity.

If you don't want to get call getTitle, then you'll need to create a public method that sets the text of your TextView in the Activity that hosts the Fragment.

In your Activity:

public void setActionBarTitle(String title){
    YOUR_CUSTOM_ACTION_BAR_TITLE.setText(title);
}

In your Fragment:

((MainFragmentActivity) getActivity()).setActionBarTitle(YOUR_TITLE);

Docs:

Activity.getTitle

Activity.setTitle

Also, you don't need to call this.whatever in the code you provided, just a tip.

Adding on to @Alexandre Aimbiré's answer - sometimes you may need to specify z-index:1 to have the element always on top while scrolling. Like this:

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;
z-index: 1;

If you're running PHP 5.3+ this will do the trick, place it at the topmost of your page:

if (get_magic_quotes_gpc() === 1)
{
    $_GET = json_decode(stripslashes(json_encode($_GET, JSON_HEX_APOS)), true);
    $_POST = json_decode(stripslashes(json_encode($_POST, JSON_HEX_APOS)), true);
    $_COOKIE = json_decode(stripslashes(json_encode($_COOKIE, JSON_HEX_APOS)), true);
    $_REQUEST = json_decode(stripslashes(json_encode($_REQUEST, JSON_HEX_APOS)), true);
}

Handles keys, values and multi-dimensional arrays.

I was tired in Searching different options for sharing view or image from my application to other application . And finally i got the solution.

Step 1 : Share Intent handling Block. This will Pop Up your window with list of Applications in you phone

public void share_bitMap_to_Apps() {

    Intent i = new Intent(Intent.ACTION_SEND);

    i.setType("image/*");
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    /*compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] bytes = stream.toByteArray();*/


    i.putExtra(Intent.EXTRA_STREAM, getImageUri(mContext, getBitmapFromView(relative_me_other)));
    try {
        startActivity(Intent.createChooser(i, "My Profile ..."));
    } catch (android.content.ActivityNotFoundException ex) {

        ex.printStackTrace();
    }


}

Step 2 : Converting your view to BItmap

public static Bitmap getBitmapFromView(View view) {
    //Define a bitmap with the same size as the view
    Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(),      view.getHeight(), Bitmap.Config.ARGB_8888);
    //Bind a canvas to it
    Canvas canvas = new Canvas(returnedBitmap);
    //Get the view's background
    Drawable bgDrawable = view.getBackground();
    if (bgDrawable != null)
        //has background drawable, then draw it on the canvas
        bgDrawable.draw(canvas);
    else
        //does not have background drawable, then draw white background on the canvas
        canvas.drawColor(Color.WHITE);
    // draw the view on the canvas
    view.draw(canvas);
    //return the bitmap
    return returnedBitmap;
}

Step 3 :

To get The URI from Bitmap Image

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);

    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

In Laravel 5.1+, you can use the value() instead of pluck.

To get first occurence, You can either use

DB::table('users')->value('name');

or use,

DB::table('users')->where('id', 1)->pluck('name')->first();

I think this is related, but I had a problem when building directly using msbuild command line (from a batch file) vs building from within VS.

Using something like the following:

<PostBuildEvent>
  MOVE /Y "$(TargetDir)something.file1" "$(ProjectDir)something.file1"
  start XCOPY /Y /R "$(SolutionDir)SomeConsoleApp\bin\$(ConfigurationName)\*" "$(ProjectDir)App_Data\Consoles\SomeConsoleApp\"
</PostBuildEvent>

(note: start XCOPY rather than XCOPY used to get around a permissions issue which prevented copying)

The macro $(SolutionDir) evaluated to ..\ when executing msbuild from a batchfile, which resulted in the XCOPY command failing. It otherwise worked fine when built from within Visual Studio. Confirmed using /verbosity:diagnostic to see the evaluated output.

Using the macro $(ProjectDir)..\ instead, which amounts to the same thing, worked fine and retained the full path in both build scenarios.

Joining fails if the DataFrames have some column names in common. The simplest way around it is to include an lsuffix or rsuffix keyword like so:

restaurant_review_frame.join(restaurant_ids_dataframe, on='business_id', how='left', lsuffix="_review")

This way, the columns have distinct names. The documentation addresses this very problem.

Or, you could get around this by simply deleting the offending columns before you join. If, for example, the stars in restaurant_ids_dataframe are redundant to the stars in restaurant_review_frame, you could del restaurant_ids_dataframe['stars'].

How about onblur event :

<input type="text" name="name" value="value" onblur="alert(1);"/>

If you have direct access to the remote repo, you could always use:

git reset --soft HEAD^

This works since there is no attempt to modify the non-existent working directory. For more details please see the original answer:

How can I uncommit the last commit in a git bare repository?

After Commenting

          // [DataType(DataType.DateTime)] 

Use the Data Annotation Attribute:

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]

The solution is to put an N in front of both the type and the SQL string to indicate it is a double-byte character string:

DECLARE @SQL NVARCHAR(100) 
SET @SQL = N'SELECT TOP 1 * FROM sys.tables' 
EXECUTE sp_executesql @SQL

Instead of writing a function to do this check, you should just be able to use this expression:

(number < 0)

Javascript will evaluate this expression by first trying to convert the left hand side to a number value before checking if it's less than zero, which seems to be what you wanted.

Specifications and details

The behavior for x < y is specified in §11.8.1 The Less-than Operator (<), which uses §11.8.5 The Abstract Relational Comparison Algorithm.

The situation is a lot different if both x and y are strings, but since the right hand side is already a number in (number < 0), the comparison will attempt to convert the left hand side to a number to be compared numerically. If the left hand side can not be converted to a number, the result is false.

Do note that this may give different results when compared to your regex-based approach, but depending on what is it that you're trying to do, it may end up doing the right thing anyway.

• "-0" < 0 is false, which is consistent with the fact that -0 < 0 is also false (see: signed zero).
• "-Infinity" < 0 is true (infinity is acknowledged)
• "-1e0" < 0 is true (scientific notation literals are accepted)
• "-0x1" < 0 is true (hexadecimal literals are accepted)
• " -1 " < 0 is true (some forms of whitespaces are allowed)

For each of the above example, the regex method would evaluate to the contrary (true instead of false and vice versa).

Appendix 1: Conditional operator ?:

It should also be said that statements of this form:

if (someCondition) {
   return valueForTrue;
} else {
   return valueForFalse;
}

can be refactored to use the ternary/conditional ?: operator (§11.12) to simply:

return (someCondition) ? valueForTrue : valueForFalse;

Idiomatic usage of ?: can make the code more concise and readable.

Appendix 2: Type conversion functions

Javascript has functions that you can call to perform various type conversions.

Something like the following:

if (someVariable) {
   return true;
} else {
   return false;
}

Can be refactored using the ?: operator to:

return (someVariable ? true : false);

But you can also further simplify this to:

return Boolean(someVariable);

This calls Boolean as a function (§15.16.1) to perform the desired type conversion. You can similarly call Number as a function (§15.17.1) to perform a conversion to number.

IMHO the coolest way is to go via WebDAV (without Network Folder, as this is often not permitted). This can be accomplished via ActiveX Data Objects as layed out in this excellent article excellent article (code can be used directly in Excel, used the concept recently).

Try Amateras. It is a very good plugin for generating UML diagrams including class diagram.

Here is function I use to fetch the url that have redirect:

const http = require('http');
const url = require('url');

function get({path, host}, callback) {
    http.get({
        path,
        host
    }, function(response) {
        if (response.headers.location) {    
            var loc = response.headers.location;
            if (loc.match(/^http/)) {
                loc = new Url(loc);
                host = loc.host;
                path = loc.path;
            } else {
                path = loc;
            }
            get({host, path}, callback);
        } else {
            callback(response);
        }
    });
}

it work the same as http.get but follow redirect.

I think the largely correct way, is to set css to this:

html
{
    overflow: hidden;
}

body
{
    margin: 0;
    box-sizing: border-box;
}

html, body
{
    height: 100%;
}

Maybe you're missing some plugins, try:

npm i --save-dev babel-plugin-transform-vue-jsx

npm i --save-dev babel-plugin-transform-runtime

npm i --save-dev babel-plugin-syntax-dynamic-import

• If using "Webpack.config.js":

• If using ".babelrc", see answer in this link.

I think a solution is to put count in back ticks

.filter("`count` >= 2")

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

Fancy C# extension method based on previous answers:

public static IWebElement SetAttribute(this IWebElement element, string name, string value)
{
    var driver = ((IWrapsDriver)element).WrappedDriver;
    var jsExecutor = (IJavaScriptExecutor)driver;
    jsExecutor.ExecuteScript("arguments[0].setAttribute(arguments[1], arguments[2]);", element, name, value);

    return element;
}

Usage:

driver.FindElement(By.Id("some_option")).SetAttribute("selected", "selected");

Best way you use CommandLineRunner or ApplicationRunner The only difference between is run() method CommandLineRunner accepts array of string and ApplicationRunner accepts ApplicationArugument.

You can make a div that has the same attributes as the <hr> tag. This way it is fully able to be customized. Here is some sample code:

The HTML:

<h3>This is a header.</h3>
<div class="customHr">.</div>

<p>Here is some sample paragraph text.<br>
This demonstrates what could go below a custom hr.</p>

The CSS:

.customHr {
    width: 95%
    font-size: 1px;
    color: rgba(0, 0, 0, 0);
    line-height: 1px;

    background-color: grey;
    margin-top: -6px;
    margin-bottom: 10px;
}

To see how the project turns out, here is a JSFiddle for the above code: http://jsfiddle.net/SplashHero/qmccsc06/1/

Another option is to use find and then pass it through sed.

find /path/to/files -type f -exec sed -i 's/oldstring/new string/g' {} \;

There is no command to do it (like you would do it with MySQL for instance). The number of Redis databases is fixed, and set in the configuration file. By default, you have 16 databases. Each database is identified by a number (not a name).

You can use the following command to know the number of databases:

CONFIG GET databases
1) "databases"
2) "16"

You can use the following command to list the databases for which some keys are defined:

INFO keyspace
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

Please note that you are supposed to use the "redis-cli" client to run these commands, not telnet. If you want to use telnet, then you need to run these commands formatted using the Redis protocol.

For instance:

*2
$4
INFO
$8
keyspace

$79
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

You can find the description of the Redis protocol here: http://redis.io/topics/protocol

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

first you need to add 2 columns to datagrid. you may do it at design time. see Columns property. then add rows as much as you need.

this.dataGridView1.Rows.Add("1", "XX");

Solution in Swift 3.1, After connecting your textfields IBOutlets set your textfields delegate in viewDidLoad, And then navigate your action in textFieldShouldReturn

class YourViewController: UIViewController,UITextFieldDelegate {

        @IBOutlet weak var passwordTextField: UITextField!
        @IBOutlet weak var phoneTextField: UITextField!

        override func viewDidLoad() {
            super.viewDidLoad()
            self.passwordTextField.delegate = self
            self.phoneTextField.delegate = self
            // Set your return type
            self.phoneTextField.returnKeyType = .next
            self.passwordTextField.returnKeyType = .done
        }

        func textFieldShouldReturn(_ textField: UITextField) -> Bool{
            if textField == self.phoneTextField {
                self.passwordTextField.becomeFirstResponder()
            }else if textField == self.passwordTextField{
                // Call login api
                self.login()
            }
            return true
        }

    }

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.

python

x = "http://xxxxxx"
y = "text title"
text_link = '<{}|{}>'.format(x,y)

post text_link in using python slack client

use jquery for that:

$("#divId").html()

The docker logs command will show you the output a container is generating when you don't run it interactively. This is likely to include the error message.

docker logs --tail 50 --follow --timestamps mediawiki_web_1

You can also run a fresh container in the foreground with docker run -ti <your_wiki_image> to see what that does. You may need to map some config from your docker-compose yml to the docker command.

I would guess that attaching to the media wiki process caused a crash which has corrupted something in your data.

Assuming you want to assign false (if applicable) to matchtime, a simpler way of writing it would be..

matchtime = ((expiryDate - DateTime.Now).TotalDays < 30);

I wondered the same myself. I found that under File(menu) there is an item "Project Settings". It opens a dialog box with 3 choices: "Default Location", "Project-relative Location", and "Custom location" "Project-relative" puts the build products in the project folder, like before. This is not in the Preferences menu and must be set every time a project is created. Hope this helps.
