the disabled attributes value is actally not considered.. usually if you have noticed the attribute is set as disabled="disabled" the "disabled" here is not necessary persay.. thus the best thing to do is to remove the attribute.

element.removeAttribute("disabled");     

also you could do

element.disabled=false;

I had a problem where the images would not show and it wasn't the relative path. I even hard coded the actual path and the image still did not show. I had changed my webserver to run on port 8080 and neither

<img src="c:/public/images/<?php echo $image->filename; ?>" width="100" />
<img src="c:/public/images/mypic.jpg" width="100" />

would not work.

<img src="../../images/<?php echo $photo->filename; ?>" width="100" />

Did not work either. This did work :

<img src="http://localhost:8080/public/images/<?php echo $image->filename; ?>" width="100" />

If you couldn't have the items OBJ equal to null, you can do this:

$scope.isEmpty = function (obj) {
    for (var i in obj) if (obj.hasOwnProperty(i)) return false;
    return true;
};

and in the view you can do:

<div ng-show="isEmpty(items)"></div>

You can do

var ob = {};
Object.keys(ob).length

Only if your browser supports ECMAScript 5. For Example, IE 8 doesn't support this feature.

See http://kangax.github.io/compat-table/es5/ for more infos

Just use

File.Copy(filepath, "\\\\192.168.1.28\\Files");

A windows fileshare exposed via a UNC path is treated as part of the file system, and has nothing to do with the web.

The credentials used will be that of the ASP.NET worker process, or any impersonation you've enabled. If you can tweak those to get it right, this can be done.

You may run into problems because you are using the IP address instead of the server name (windows trust settings prevent leaving the domain - by using IP you are hiding any domain details). If at all possible, use the server name!

If this is not on the same windows domain, and you are trying to use a different domain account, you will need to specify the username as "[domain_or_machine]\[username]"

If you need to specify explicit credentials, you'll need to look into coding an impersonation solution.

My conditions

• Create-React-App
• React-scripts v3.2
• Froala rich text editor v3.1
• Development mode worked fine
• The production build was broken with the error mentioned in the question

Solution to my problem

Downgrade Froala to v3.0.

Something in v3.1 broke our Create React App build process.

Update: Use react scripts v3.3

We discovered that there was an issue between React Scripts 3.2 and Froala 3.1.

Updating to React Scripts v3.3 allowed us to upgrade to Froala 3.1.

Use this if you're in the fragment.

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

            getFragmentManager().beginTransaction().remove((Fragment) youfragmentname).commitAllowingStateLoss();

        }

What variables do you want to print? If you mean QStrings, those need to be converted to c-Strings. Try:

std::cout << myString.toAscii().data();

There is a new function in SQL called string_split if you are using list of string. Ref Link STRING_SPLIT (Transact-SQL)

DECLARE @tags NVARCHAR(400) = 'clothing,road,,touring,bike'
SELECT value
FROM STRING_SPLIT(@tags, ',')
WHERE RTRIM(value) <> '';

you can pass this query with in as follows:

SELECT *
  FROM [dbo].[yourTable]
  WHERE (strval IN (SELECT value FROM STRING_SPLIT(@tags, ',') WHERE RTRIM(value) <> ''))

The classical answer that works in almost every environment is

SELECT ID, Name, blah, blah
FROM TableB TB
LEFT JOIN TableA TA
ON TB.ID=TA.ID
WHERE TA.ID IS NULL

sometimes NOT EXISTS may be not implemented (not working).

TextView txtview = new TextView(v.getContext());
LayoutParams params = new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
txtview.setLayoutParams(params);

1f is denotes as weight=1; you can give 2f or 3f, views will move accoding to the space

Can I control the HTTP headers sent by window.open (cross browser)?

No

If not, can I somehow window.open a page that then issues my request with custom headers inside its popped-up window?

• You can request a URL that triggers a server side program which makes the request with arbitrary headers and then returns the response
• You can run JavaScript (probably saying goodbye to Progressive Enhancement) that uses XHR to make the request with arbitrary headers (assuming the URL fits within the Same Origin Policy) and then process the result in JS.

I need some cunning hacks...

It might help if you described the problem instead of asking if possible solutions would work.

For those looking a more modern approach, you can use the fetch API. The following example shows how to download a spreadsheet file. It is easily done with the following code.

fetch(url, {
    body: JSON.stringify(data),
    method: 'POST',
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    },
})
.then(response => response.blob())
.then(response => {
    const blob = new Blob([response], {type: 'application/application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'});
    const downloadUrl = URL.createObjectURL(blob);
    const a = document.createElement("a");
    a.href = downloadUrl;
    a.download = "file.xlsx";
    document.body.appendChild(a);
    a.click();
})

I believe this approach to be much easier to understand than other XMLHttpRequest solutions. Also, it has a similar syntax to the jQuery approach, without the need to add any additional libraries.

Of course, I would advise checking to which browser you are developing, since this new approach won't work on IE. You can find the full browser compatibility list on the following link.

Important: In this example I am sending a JSON request to a server listening on the given url. This url must be set, on my example I am assuming you know this part. Also, consider the headers needed for your request to work. Since I am sending a JSON, I must add the Content-Type header and set it to application/json; charset=utf-8, as to let the server know the type of request it will receive.

I found that on Mavericks 10.8 there wasn't a .bash_profile and my paths were located in /etc/paths

In order to have the new path (whether this is a mamp or brew install of php) take effect it needs to be above the default /usr/bin/php in this paths file. eg.

/Applications/MAMP/bin/php/php5.3.6/bin
/usr/bin 

AFter the change, open a new terminal window and run 'which php' that should now point to your updated path

For me the code:

<form (submit)="addTodo()">_x000D_
  <input type="text" [(ngModel)]="text">_x000D_
</form>

throws error, but I added name attribute to input:

<form (submit)="addTodo()">_x000D_
  <input type="text" [(ngModel)]="text" name="text">_x000D_
</form>

and it started to work.

This needs to be done on the server-side, where the cookie was issued.

You might consider this Open Source tool, matiri, https://github.com/AAFC-MBB/matiri which is a concurrent mysql backup script with metadata in Sqlite3. Features:

• Multi-Server: Multiple MySQL servers are supported whether they are co-located on the same or separate physical servers.
• Parallel: Each database on the server to be backed up is done separately, in parallel (concurrency settable: default: 3)
• Compressed: Each database backup compressed
• Checksummed: SHA256 of each compressed backup file stored and the archive of all files
• Archived: All database backups tar'ed together into single file
• Recorded: Backup information stored in Sqlite3 database

Not certain what the HTML looks like (that would help with answers). If it's

<div class="testimonials content">stuff</div>

then simply remove the space in your css. A la...

.testimonials.content { css here }

UPDATE:

Okay, after seeing HTML see if this works...

.testimonials .wrapper .content { css here }

or just

.testimonials .wrapper { css here }

or

.desc-container .wrapper { css here }

all 3 should work.

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.

Shutdown hooks execute in all cases where the VM is not forcibly killed. So, if you were to issue a "standard" kill (SIGTERM from a kill command) then they will execute. Similarly, they will execute after calling System.exit(int).

However a hard kill (kill -9 or kill -SIGKILL) then they won't execute. Similarly (and obviously) they won't execute if you pull the power from the computer, drop it into a vat of boiling lava, or beat the CPU into pieces with a sledgehammer. You probably already knew that, though.

Finalizers really should run as well, but it's best not to rely on that for shutdown cleanup, but rather rely on your shutdown hooks to stop things cleanly. And, as always, be careful with deadlocks (I've seen far too many shutdown hooks hang the entire process)!

In the terminal, you are running the node application and it is running your script. That is a very different execution environment than directly running your script in the browser. While the Javascript language is largely the same (both V8 if you're running the Chrome browser), the rest of the execution environment such as libraries available are not the same.

node.js is a server-side Javascript execution environment that combines the V8 Javascript engine with a bunch of server-side libraries. require() is one such feature that node.js adds to the environment. So, when you run node in the terminal, you are running an environment that contains require().

require() is not a feature that is built into the browser. That is a specific feature of node.js, not of a browser. So, when you try to have the browser run your script, it does not have require().

There are ways to run some forms of node.js code in a browser (but not all). For example, you can get browser substitutes for require() that work similarly (though not identically).

But, you won't be running a web server in your browser as that is not something the browser has the capability to do.

You may be interested in browserify which lets you use node-style modules in a browser using require() statements.

You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

Assuming that the items in your CheckedListBox are strings:

  for (int i = 0; i < checkedListBox1.Items.Count; i++)
  {
    if ((string)checkedListBox1.Items[i] == value)
    {
      checkedListBox1.SetItemChecked(i, true);
    }
  }

Or

  int index = checkedListBox1.Items.IndexOf(value);

  if (index >= 0)
  {
    checkedListBox1.SetItemChecked(index, true);
  }

If you $ is defined then You can iterate

var data={"id" : 1, "second" : "abcd"};
$.each(data, function() {
  var key = Object.keys(this)[0];
  var value = this[key];
  //do something with value;
}); 

You can access it by following way If you know the values of keys

data.id

or

data["id"]

I would NOT use mach_absolute_time() because it queries a combination of the kernel and the processor for an absolute time using ticks (probably an uptime).

What I would use:

CFAbsoluteTimeGetCurrent();

This function is optimized to correct the difference in the iOS and OSX software and hardware.

Something Geekier

The quotient of a difference in mach_absolute_time() and AFAbsoluteTimeGetCurrent() is always around 24000011.154871

Here is a log of my app:

Please note that final result time is a difference in CFAbsoluteTimeGetCurrent()'s

Code snippet underneath!

Please take a look at these documentations and examples at MDN, and you will find your answer. This is the propper way to do it I would say.

Creating and triggering events

Dispatch Event (example)

Taken from the 'Dispatch Event (example)'-HTML-link (simulate click):

function simulateClick() {

  var evt = document.createEvent("MouseEvents");

  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);

  var cb = document.getElementById("checkbox"); 
  var canceled = !cb.dispatchEvent(evt);

  if(canceled) {
    // A handler called preventDefault
    alert("canceled");
  } else {
    // None of the handlers called preventDefault
    alert("not canceled");
  }
}

This is how I would do it (2017 ..) :

Simply using MouseEvent.

function simulateClick() {

    var evt = new MouseEvent("click");

    var cb = document.getElementById("checkbox");
    var canceled = !cb.dispatchEvent(evt);

    if (canceled) {
        // A handler called preventDefault
        console.log("canceled");
    } else {
        // None of the handlers called preventDefault
        console.log("not canceled");
    }
}

document.getElementById("button").onclick = evt => {_x000D_
    _x000D_
    simulateClick()_x000D_
}_x000D_
_x000D_
function simulateClick() {_x000D_
_x000D_
    var evt = new MouseEvent("click");_x000D_
_x000D_
    var cb = document.getElementById("checkbox");_x000D_
    var canceled = !cb.dispatchEvent(evt);_x000D_
_x000D_
    if (canceled) {_x000D_
        // A handler called preventDefault_x000D_
        console.log("canceled");_x000D_
    } else {_x000D_
        // None of the handlers called preventDefault_x000D_
        console.log("not canceled");_x000D_
    }_x000D_
}

<input type="checkbox" id="checkbox">_x000D_
<br>_x000D_
<br>_x000D_
<button id="button">Check it out, or not</button>

My problem was I had 2 JAR's and I was trying to override one with the other based on its order in the Java Build Path => Order & Export tab in Eclipse, because one was for debugging and the other was not (the debugging JAR being first in the order). When I did it this way, I had to manually attach a source.

I tried removing the non-debug JAR and placing the debug JAR in my \WEB-INF\lib\ directory, cleaning, building, etc., and it worked. This time (having removed the attached source), it automatically would let me navigate through the debug code, without having to attach any source manually. Breakpoints and debug also worked.

In case anyone is still having trouble, I also tried all of these particular solutions mentioned in the other answers:

• Uncheck, apply, and recheck Add line number attributes...
• Manually editing org.eclipse.jdt.core.prefs as mentioned in another answer: https://stackoverflow.com/a/31588700/1599699
• Ensuring the JAR was being generated with debug enabled.
• Changing the JDK compliance level from 1.6 to 1.7 (thereby matching the JDK I was using).

I also did the usual shutting down of the server (and making sure java.exe is actually closed...), deleting the \build\ directories in both projects, restarting Eclipse with the -clean parameter, recreating the debug JAR, refreshing, cleaning, and building the project with the debug JAR in it, starting the server in debug mode, publishing/cleaning, and breakpointing.

From Linux Terminal:

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

From Windows PowerShell:

adb shell 
getprop | grep -e 'model' -e 'version.sdk' -e 'manufacturer' -e 'hardware' -e 'platform' -e 'revision' -e 'serialno' -e 'product.name' -e 'brand'

You can use ES6 backtick syntax too

<a href={`/customer/${item._id}`} >{item.get('firstName')} {item.get('lastName')}</a>

More info on es6 template literals

Not sure but try :

elemm.addEventListener('click', function(){ alert('blah');}, false);

This is really weird, why nobody is mentioning the /IM switch ?! I've been using it for a long time in backup jobs. But I tried googling just now and I couldn't land on a single web page that says anything about it even on MS website !!! Also found so many user posts complaining about the same issue!!

Anyway.. to use Robocopy to overwrite EVERYTHING what ever size or time in source or distination you must include these three switches in your command (/IS /IT /IM)

/IS :: Include Same files. (Includes same size files)
/IT :: Include Tweaked files. (Includes same files with different Attributes)
/IM :: Include Modified files (Includes same files with different times).

This is the exact command I use to transfer few TeraBytes of mostly 1GB+ files (ISOs - Disk Images - 4K Videos):

robocopy B:\Source D:\Destination /E /J /COPYALL /MT:1 /DCOPY:DATE /IS /IT /IM /X /V /NP /LOG:A:\ROBOCOPY.LOG

I did a small test for you .. and here is the result:

               Total    Copied   Skipped  Mismatch    FAILED    Extras

Dest, Disk: WD Gold 6TB (Compare the write speed with my result)

Even with those "Extras", that's for reporting only because of the "/X" switch. As you can see nothing was Skipped and Total number and size of all files are equal to the Copied. Sometimes It will show small number of skipped files when I abuse it and cancel it multiple times during operation but even with that the values in the first 2 columns are always Equal. I also confirmed that once before by running a PowerShell script that scans all files in destination and generate a report of all time-stamps.

Some performance tips from my history with it and so many tests & troubles!:

. Despite of what most users online advise to use maximum threads "/MT:128" like it's a general trick to get the best performance ... PLEASE DON'T USE "/MT:128" WITH VERY LARGE FILES ... that's a big mistake and it will decrease your drive performance dramatically after several runs .. it will create very high fragmentation or even cause the files system to fail in some cases and you end up spending valuable time trying to recover a RAW partition and all that nonsense. And above all that, It will perform 4-6 times slower!!

For very large files:

1. Use Only "One" thread "/MT:1" | Impact: BIG
2. Must use "/J" to disable buffering. | Impact: High
3. Use "/NP" with "/LOG:file" and Don't output to the console by "/TEE" | Impact: Medium.
4. Put the "/LOG:file" on a separate drive from the source or destination | Impact: Low.

For regular big files:

1. Use multi threads, I would not exceed "/MT:4" | Impact: BIG
2. IF destination disk has low Cache specs use "/J" to disable buffering | Impact: High
3. & 4 same as above.

For thousands of tiny files:

1. Go nuts :) with Multi threads, at first I would start with 16 and multibly by 2 while monitoring the disk performance. Once it starts dropping I'll fall back to the prevouse value and stik with it | Impact: BIG
2. Don't use "/J" | Impact: High
3. Use "/NP" with "/LOG:file" and Don't output to the console by "/TEE" | Impact: HIGH.
4. Put the "/LOG:file" on a separate drive from the source or destination | Impact: HIGH.

There are various ways to achieve this. Here are three.

    Map<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    System.out.println("using entrySet and toString");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry);
    }
    System.out.println();

    System.out.println("using entrySet and manual string creation");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
    System.out.println();

    System.out.println("using keySet");
    for (String key : map.keySet()) {
        System.out.println(key + "=" + map.get(key));
    }
    System.out.println();

Output

using entrySet and toString
key1=value1
key2=value2
key3=value3

using entrySet and manual string creation
key1=value1
key2=value2
key3=value3

using keySet
key1=value1
key2=value2
key3=value3

This worked for me:

$(window).scroll(function() {
  buffer = 40 // # of pixels from bottom of scroll to fire your function. Can be 0
  if ($(".myDiv").prop('scrollHeight') - $(".myDiv").scrollTop() <= $(".myDiv").height() + buffer )   {
    doThing();
  }
});

Must use jQuery 1.6 or higher

This is the easiest way i have found to do it.

List<List<String>> matrix= new List<List<String>>(); //Creates new nested List
matrix.Add(new List<String>()); //Adds new sub List
matrix[0].Add("2349"); //Add values to the sub List at index 0
matrix[0].Add("The Prime of Your Life");
matrix[0].Add("Daft Punk");
matrix[0].Add("Human After All");
matrix[0].Add("3");
matrix[0].Add("2");

To retrieve values is even easier

string title = matrix[0][1]; //Retrieve value at index 1 from sub List at index 0

Bootstrap uses CSS3 transitions so progress bars are automatically animated when you set the width of .bar trough javascript / jQuery.

http://jsfiddle.net/3j5Je/ ..see?

Macintosh HD/Library/WebServer/Documents

Macintosh HD is the name of your HD

If you can't find it: Open Finder > click "Go" at the very top > Computer > Your HD should be there. You can drag and drop the HD to favorites on the left.

For zsh the syntax is slightly different, but still shorter than most answers here:

> str1='mAtCh'
> str2='MaTcH'
> [[ "$str1:u" = "$str2:u" ]] && echo 'Strings Match!'
Strings Match!
>

This will convert both strings to uppercase before the comparison.

Another method makes use zsh's globbing flags, which allows us to directly make use of case-insensitive matching by using the i glob flag:

setopt extendedglob
[[ $str1 = (#i)$str2 ]] && echo "Match success"

Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.

Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

Set display: table for parent div and display: table-cell for children divs

HTML :

<div class="container-fluid">
  <div class="row justify-content-center display-as-table">

    <div class="col-4 hidden-md-down" id="yellow">
      XXXX<br />
      XXXX<br />
      XXXX<br />
      XXXX<br />
      XXXX<br />
      XXXX<br />vv
      XXXX<br />
    </div>

    <div class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8" id="red">
      Form Goes Here
    </div>
  </div>
</div>

CSS:

#yellow {
  height: 100%;
  background: yellow;
  width: 50%;
}
#red {background: red}

.container-fluid {bacgkround: #ccc}

/* this is the part make equal height */
.display-as-table {display: table; width: 100%;}
.display-as-table > div {display: table-cell; float: none;}

Version 3.6+: Use a formatted string literal, f-string for short

print(f"{i}. {key} appears {wordBank[key]} times.")

Here's a good one:

Set line-height equal to whatever the height is; works like a charm!

E.g:

li {
    height: 30px;
    line-height: 30px;
}

I could be wrong, but I thought that slashes only appeared in branch names when they related to a remote repo, for example origin/master.

When displaying I sometimes make a new file called Funk. This will have the font, size etc. This is the code for the class:

import pygame

def text_to_screen(screen, text, x, y, size = 50,
            color = (200, 000, 000), font_type = 'data/fonts/orecrusherexpand.ttf'):
    try:

        text = str(text)
        font = pygame.font.Font(font_type, size)
        text = font.render(text, True, color)
        screen.blit(text, (x, y))

    except Exception, e:
        print 'Font Error, saw it coming'
        raise e

Then when that has been imported when I want to display text taht updates E.G score I do:

Funk.text_to_screen(screen, 'Text {0}'.format(score), xpos, ypos)

If it is just normal text that isn't being updated:

Funk.text_to_screen(screen, 'Text', xpos, ypos)

You may notice {0} on the first example. That is because when .format(whatever) is used that is what will be updated. If you have something like Score then target score you'd do {0} for score then {1} for target score then .format(score, targetscore)

If you need a number greater than 999,999.00 you will have a problem.
These are only good for numbers less than 1 million, 1,000,000.
They only remove 1 or 2 commas.

Here the script that can remove up to 12 commas:

function uncomma(x) {
  var string1 = x;
  for (y = 0; y < 12; y++) {
    string1 = string1.replace(/\,/g, '');
  }
  return string1;
}

Modify that for loop if you need bigger numbers.

One more addition: if you need to sync files by its extensions in one dir only (without of recursion) you should use a construction like this:

rsync -auzv --include './' --include '*.ext' --exclude '*' /source/dir/ /destination/dir/

Pay your attention to the dot in the first --include. --no-r does not work in this construction.

EDIT:

Thanks to gbyte.co for the valuable comment!

What about putting it into cron.hourly, waiting until the next run of hourly cron jobs, then removing it? That would run it once within an hour, and in the cron environment. You can also run ./your_script, but that won't have the same environment as under cron.

Don't abuse form elements where <a> elements will suffice.

<style>
    /* or put this in your stylesheet */

    .button {
        display: inline-block;
        padding: 3px 5px;
        border: 1px solid #000;
        background: #eee;
    }

</style>

<!-- instead of abusing a button or input element -->
<a href="url" class="button">text</a>

It should be,

*/15 * * * *  your_command_or_whatever

If someone is interested in the similar problem, but is not working with XAML, here's my solution:

var B1 = new Border();
B1.BorderBrush = Brushes.Black;
B1.BorderThickness = new Thickness(0, 1, 0, 0); // You can specify here which borders do you want
YourPanel.Children.Add(B1);

Here's a simple method to do it: The (ip >> 8), (ip >> 16) and (ip >> 24) moves the 2nd, 3rd and 4th bytes into the lower order byte, while the & 0xFF isolates the least significant byte at each step.

void print_ip(unsigned int ip)
{
    unsigned char bytes[4];
    bytes[0] = ip & 0xFF;
    bytes[1] = (ip >> 8) & 0xFF;
    bytes[2] = (ip >> 16) & 0xFF;
    bytes[3] = (ip >> 24) & 0xFF;   
    printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);        
}

There is an implied bytes[0] = (ip >> 0) & 0xFF; at the first step.

Use snprintf() to print it to a string.

You could also just use jQuery to remove the contents of the div that contains your svg.

$("#container_div_id").html("");

This worked for me just by restarting android studio 2 times :D. I'm using Android Studio 2.1.

you can do it for example with

UPDATE `table` SET `date`='', `newdate`=NULL WHERE id='$id'

ActiveXObject is available only on IE browser. So every other useragent will throw an error

On modern browser you could use instead File API or File writer API (currently implemented only on Chrome)

So here's how to do that:

In the bottom bar of VSCode, you'll see the label UTF-8. Click it. A popup opens. Click Save with encoding. You can now pick a new encoding for that file.

Alternatively, you can change the setting globally in Workspace/User settings using the setting "files.encoding": "utf8". If using the graphical settings page in VSCode, simply search for encoding. Do note however that this only applies to newly created files.

How about using asp:LinkButton?

There are a few ways:

• $0 is the currently executing script as provided by POSIX, relative to the current working directory if the script is at or below the CWD
• Additionally, cwd(), getcwd() and abs_path() are provided by the Cwd module and tell you where the script is being run from
• The module FindBin provides the $Bin & $RealBin variables that usually are the path to the executing script; this module also provides $Script & $RealScript that are the name of the script
• __FILE__ is the actual file that the Perl interpreter deals with during compilation, including its full path.

I've seen the first three ($0, the Cwd module and the FindBin module) fail under mod_perl spectacularly, producing worthless output such as '.' or an empty string. In such environments, I use __FILE__ and get the path from that using the File::Basename module:

use File::Basename;
my $dirname = dirname(__FILE__);

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

boolean can only be true or false because it's a primitive datatype (+ a boolean variables default value is false). You can use the class Boolean instead if you want to use null values. Boolean is a reference type, that's the reason you can assign null to a Boolean "variable". Example:

Boolean testvar = null;
if (testvar == null) { ...}

Ok, so you've switched the column from Number to VARCHAR(5). Now you need to update the zipcode field to be left-padded. The SQL to do that would be:

UPDATE MyTable
SET ZipCode = LPAD( ZipCode, 5, '0' );

This will pad all values in the ZipCode column to 5 characters, adding '0's on the left.

Of course, now that you've got all of your old data fixed, you need to make sure that your any new data is also zero-padded. There are several schools of thought on the correct way to do that:

• Handle it in the application's business logic. Advantages: database-independent solution, doesn't involve learning more about the database. Disadvantages: needs to be handled everywhere that writes to the database, in all applications.

• Handle it with a stored procedure. Advantages: Stored procedures enforce business rules for all clients. Disadvantages: Stored procedures are more complicated than simple INSERT/UPDATE statements, and not as portable across databases. A bare INSERT/UPDATE can still insert non-zero-padded data.

• Handle it with a trigger. Advantages: Will work for Stored Procedures and bare INSERT/UPDATE statements. Disadvantages: Least portable solution. Slowest solution. Triggers can be hard to get right.

In this case, I would handle it at the application level (if at all), and not the database level. After all, not all countries use a 5-digit Zipcode (not even the US -- our zipcodes are actually Zip+4+2: nnnnn-nnnn-nn) and some allow letters as well as digits. Better NOT to try and force a data format and to accept the occasional data error, than to prevent someone from entering the correct value, even though it's format isn't quite what you expected.

I found this and it seemed to fix my issue.

GitHub Fix Docker Daemon Crash

I changed the content of my docker-compose-deps.yml file as seen in the link. Then I ran docker-compose -f docker-compose-deps.yml up -d. Then I changed it back and it worked for some reason. I didn't have to continue the steps in the link I provided, but the first two steps fixed the issue for me.

I use metaclasses and decorators for generate tests. You can check my implementation python_wrap_cases. This library doesn't require any test frameworks.

Your example:

import unittest
from python_wrap_cases import wrap_case


@wrap_case
class TestSequence(unittest.TestCase):

    @wrap_case("foo", "a", "a")
    @wrap_case("bar", "a", "b")
    @wrap_case("lee", "b", "b")
    def testsample(self, name, a, b):
        print "test", name
        self.assertEqual(a, b)

Console output:

testsample_u'bar'_u'a'_u'b' (tests.example.test_stackoverflow.TestSequence) ... test bar
FAIL
testsample_u'foo'_u'a'_u'a' (tests.example.test_stackoverflow.TestSequence) ... test foo
ok
testsample_u'lee'_u'b'_u'b' (tests.example.test_stackoverflow.TestSequence) ... test lee
ok

Also you may use generators. For example this code generate all possible combinations of tests with arguments a__list and b__list

import unittest
from python_wrap_cases import wrap_case


@wrap_case
class TestSequence(unittest.TestCase):

    @wrap_case(a__list=["a", "b"], b__list=["a", "b"])
    def testsample(self, a, b):
        self.assertEqual(a, b)

Console output:

testsample_a(u'a')_b(u'a') (tests.example.test_stackoverflow.TestSequence) ... ok
testsample_a(u'a')_b(u'b') (tests.example.test_stackoverflow.TestSequence) ... FAIL
testsample_a(u'b')_b(u'a') (tests.example.test_stackoverflow.TestSequence) ... FAIL
testsample_a(u'b')_b(u'b') (tests.example.test_stackoverflow.TestSequence) ... ok

Wanna a list of folder in xampp?

Just delete or change the file index.php to index.txt. And you will get the list just typing url: localhost.

The safest way to do it is to fully specify the columns both for insertion and extraction. There's no guarantee (to the application) that either of these will be the order you think they may be.

insert into dues_storage (f1, f2, f3, cd)
    select f1, f2, f3, current_date() from dues where id = 5;

If you're worried about having to change many multiple PHP pages that do this (as you seem to indicate in the comment to another answer), this is ripe for a stored procedure. That way, all your PHP pages simply call the stored procedure with (for example) just the ID to copy and it controls the actual copy process. That way, there's only one place where you need to maintain the code, and, in my opinion, the DBMS is the right place to do it.

window.location.href, this as saved my life in webview from Android 5.1. The page don't reload with location.reload() in this version from Android.

You can simply add data attribute in html input tag:

In rails html :

<%= form.text_field :appointment_date, 'data-provide': 'datepicker', 'data-date-start-date': "+0d" %>

HTML :

<input data-provide="datepicker" data-date-start-date="+0d" type="text" name="appointment_date" id="appointment_date">

As already mentioned, spring-boot will fetch all you need (for both web and webflux starter).

But what's even better - you don't need to register any modules yourself. Take a look here. Since @SpringBootApplication uses @EnableAutoConfiguration under the hood, it means JacksonAutoConfiguration will be added to the context automatically. Now, if you look inside JacksonAutoConfiguration, you will see:

    private void configureModules(Jackson2ObjectMapperBuilder builder) {
        Collection<Module> moduleBeans = getBeans(this.applicationContext,
                Module.class);
        builder.modulesToInstall(moduleBeans.toArray(new Module[0]));
    }

This fella will be called in the process of initialization and will fetch all the modules it can find in the classpath. (I use Spring Boot 2.1)

You can use the formula INDIRECT().

This basically takes a string and treats it as a reference. In your case, you would use:

=INDIRECT("'"&A5&"'!G7")

The double quotes are to show that what's inside are strings, and only A5 here is a reference.

I had a look at multiple answers across stack overflow and the web while trying to set-up a way of doing multiprocessing using queues for passing around large pandas dataframes. It seemed to me that every answer was re-iterating the same kind of solutions without any consideration of the multitude of edge cases one will definitely come across when setting up calculations like these. The problem is that there is many things at play at the same time. The number of tasks, the number of workers, the duration of each task and possible exceptions during task execution. All of these make synchronization tricky and most answers do not address how you can go about it. So this is my take after fiddling around for a few hours, hopefully this will be generic enough for most people to find it useful.

Some thoughts before any coding examples. Since queue.Empty or queue.qsize() or any other similar method is unreliable for flow control, any code of the like

while True:
    try:
        task = pending_queue.get_nowait()
    except queue.Empty:
        break

is bogus. This will kill the worker even if milliseconds later another task turns up in the queue. The worker will not recover and after a while ALL the workers will disappear as they randomly find the queue momentarily empty. The end result will be that the main multiprocessing function (the one with the join() on the processes) will return without all the tasks having completed. Nice. Good luck debugging through that if you have thousands of tasks and a few are missing.

The other issue is the use of sentinel values. Many people have suggested adding a sentinel value in the queue to flag the end of the queue. But to flag it to whom exactly? If there is N workers, assuming N is the number of cores available give or take, then a single sentinel value will only flag the end of the queue to one worker. All the other workers will sit waiting for more work when there is none left. Typical examples I've seen are

while True:
    task = pending_queue.get()
    if task == SOME_SENTINEL_VALUE:
        break

One worker will get the sentinel value while the rest will wait indefinitely. No post I came across mentioned that you need to submit the sentinel value to the queue AT LEAST as many times as you have workers so that ALL of them get it.

The other issue is the handling of exceptions during task execution. Again these should be caught and managed. Moreover, if you have a completed_tasks queue you should independently count in a deterministic way how many items are in the queue before you decide that the job is done. Again relying on queue sizes is bound to fail and returns unexpected results.

In the example below, the par_proc() function will receive a list of tasks including the functions with which these tasks should be executed alongside any named arguments and values.

import multiprocessing as mp
import dill as pickle
import queue
import time
import psutil

SENTINEL = None


def do_work(tasks_pending, tasks_completed):
    # Get the current worker's name
    worker_name = mp.current_process().name

    while True:
        try:
            task = tasks_pending.get_nowait()
        except queue.Empty:
            print(worker_name + ' found an empty queue. Sleeping for a while before checking again...')
            time.sleep(0.01)
        else:
            try:
                if task == SENTINEL:
                    print(worker_name + ' no more work left to be done. Exiting...')
                    break

                print(worker_name + ' received some work... ')
                time_start = time.perf_counter()
                work_func = pickle.loads(task['func'])
                result = work_func(**task['task'])
                tasks_completed.put({work_func.__name__: result})
                time_end = time.perf_counter() - time_start
                print(worker_name + ' done in {} seconds'.format(round(time_end, 5)))
            except Exception as e:
                print(worker_name + ' task failed. ' + str(e))
                tasks_completed.put({work_func.__name__: None})


def par_proc(job_list, num_cpus=None):

    # Get the number of cores
    if not num_cpus:
        num_cpus = psutil.cpu_count(logical=False)

    print('* Parallel processing')
    print('* Running on {} cores'.format(num_cpus))

    # Set-up the queues for sending and receiving data to/from the workers
    tasks_pending = mp.Queue()
    tasks_completed = mp.Queue()

    # Gather processes and results here
    processes = []
    results = []

    # Count tasks
    num_tasks = 0

    # Add the tasks to the queue
    for job in job_list:
        for task in job['tasks']:
            expanded_job = {}
            num_tasks = num_tasks + 1
            expanded_job.update({'func': pickle.dumps(job['func'])})
            expanded_job.update({'task': task})
            tasks_pending.put(expanded_job)

    # Use as many workers as there are cores (usually chokes the system so better use less)
    num_workers = num_cpus

    # We need as many sentinels as there are worker processes so that ALL processes exit when there is no more
    # work left to be done.
    for c in range(num_workers):
        tasks_pending.put(SENTINEL)

    print('* Number of tasks: {}'.format(num_tasks))

    # Set-up and start the workers
    for c in range(num_workers):
        p = mp.Process(target=do_work, args=(tasks_pending, tasks_completed))
        p.name = 'worker' + str(c)
        processes.append(p)
        p.start()

    # Gather the results
    completed_tasks_counter = 0
    while completed_tasks_counter < num_tasks:
        results.append(tasks_completed.get())
        completed_tasks_counter = completed_tasks_counter + 1

    for p in processes:
        p.join()

    return results

And here is a test to run the above code against

def test_parallel_processing():
    def heavy_duty1(arg1, arg2, arg3):
        return arg1 + arg2 + arg3

    def heavy_duty2(arg1, arg2, arg3):

plus another one with some exceptions

    results = par_proc(task_list)

    assert job2 == 21

Hope that is helpful.

AngularJs lets you to use filters inside template or inside Controller, Directive etc..

in template you can use this syntax

{{ variable | MyFilter: ... : ... }}

and inside controller you can use injecting the $filter service

angular.module('MyModule').controller('MyCtrl',function($scope, $filter){
    $filter('MyFilter')(arg1, arg2);
})

In IDP Init SSO (Unsolicited Web SSO) the Federation process is initiated by the IDP sending an unsolicited SAML Response to the SP. In SP-Init, the SP generates an AuthnRequest that is sent to the IDP as the first step in the Federation process and the IDP then responds with a SAML Response. IMHO ADFSv2 support for SAML2.0 Web SSO SP-Init is stronger than its IDP-Init support re: integration with 3rd Party Fed products (mostly revolving around support for RelayState) so if you have a choice you'll want to use SP-Init as it'll probably make life easier with ADFSv2.

Here are some simple SSO descriptions from the PingFederate 8.0 Getting Started Guide that you can poke through that may help as well -- https://documentation.pingidentity.com/pingfederate/pf80/index.shtml#gettingStartedGuide/task/idpInitiatedSsoPOST.html

Some examples on working with nullable DateTime values.

(See Nullable Value Types (Visual Basic) for more.)

'
' An ordinary DateTime declaration. It is *not* nullable. Setting it to
' 'Nothing' actually results in a non-null value.
'
Dim d1 As DateTime = Nothing
Console.WriteLine(String.Format("d1 = [{0}]\n", d1))
' Output:  d1 = [1/1/0001 12:00:00 AM]

' Console.WriteLine(String.Format("d1 is Nothing? [{0}]\n", (d1 Is Nothing)))
'
'   Compilation error on above expression '(d1 Is Nothing)':
'
'      'Is' operator does not accept operands of type 'Date'.
'       Operands must be reference or nullable types.

'
' Three different but equivalent ways to declare a DateTime
' nullable:
'
Dim d2? As DateTime = Nothing
Console.WriteLine(String.Format("d2 = [{0}][{1}]\n", d2, (d2 Is Nothing)))
' Output:  d2 = [][True]

Dim d3 As DateTime? = Nothing
Console.WriteLine(String.Format("d3 = [{0}][{1}]\n", d3, (d3 Is Nothing)))
' Output:  d3 = [][True]

Dim d4 As Nullable(Of DateTime) = Nothing
Console.WriteLine(String.Format("d4 = [{0}][{1}]\n", d4, (d4 Is Nothing)))
' Output:  d4 = [][True]

Also, on how to check whether a variable is null (from Nothing (Visual Basic)):

When checking whether a reference (or nullable value type) variable is null, do not use = Nothing or <> Nothing. Always use Is Nothing or IsNot Nothing.

Cast a pointer to the floating point variable as something like an unsigned int. Then you can shift and mask the bits to get each component.

float foo;
unsigned int ival, mantissa, exponent, sign;

foo = -21.4f;
ival = *((unsigned int *)&foo);
mantissa = ( ival & 0x7FFFFF);
ival = ival >> 23;
exponent = ( ival  & 0xFF );
ival = ival >> 8;
sign = ( ival & 0x01 );

Obviously you probably wouldn't use unsigned ints for the exponent and sign bits but this should at least give you the idea.

Using ant debug after building build.xml file :

in your cmd your root should be your project at first then use the ant debug command e.g:

c:\testApp>ant debug 

It maybe not exactly what you are looking for, but
Google's Chart API is pretty cool and easy to use.

You can also use this very simplified form:

@Html.ActionLink("Come back to Home", "Index", "Home")

Where :
Come back to Home is the text that will appear on the page
Index is the view name
Homeis the controller name

For anyone that this might be handy for, here is a jQuery dependent function I had success with for applying a CSS animation via a CSS class, then getting a callback from afterwards. It may not work perfectly since I had it being used in a Backbone.js App, but maybe useful.

var cssAnimate = function(cssClass, callback) {
    var self = this;

    // Checks if correct animation has ended
    var setAnimationListener = function() {
        self.one(
            "webkitAnimationEnd oanimationend msAnimationEnd animationend",
            function(e) {
                if(
                    e.originalEvent.animationName == cssClass &&
                    e.target === e.currentTarget
                ) {
                    callback();
                } else {
                    setAnimationListener();
                }
            }
        );
    }

    self.addClass(cssClass);
    setAnimationListener();
}

I used it kinda like this

cssAnimate.call($("#something"), "fadeIn", function() {
    console.log("Animation is complete");
    // Remove animation class name?
});

Original idea from http://mikefowler.me/2013/11/18/page-transitions-in-backbone/

And this seems handy: http://api.jqueryui.com/addClass/

Update

After struggling with the above code and other options, I would suggest being very cautious with any listening for CSS animation ends. With multiple animations going on, this can get messy very fast for event listening. I would strongly suggest an animation library like GSAP for every animation, even the small ones.

In Postgres, you can also use the special DISTINCT ON (expression) syntax:

SELECT DISTINCT ON (cname) 
    cname, wmname, avg
FROM 
    makerar 
ORDER BY 
    cname, avg DESC ;

A JTextField was designed to use an ActionListener just like a JButton is. See the addActionListener() method of JTextField.

For example:

Action action = new AbstractAction()
{
    @Override
    public void actionPerformed(ActionEvent e)
    {
        System.out.println("some action");
    }
};

JTextField textField = new JTextField(10);
textField.addActionListener( action );

Now the event is fired when the Enter key is used.

Also, an added benefit is that you can share the listener with a button even if you don't want to make the button a default button.

JButton button = new JButton("Do Something");
button.addActionListener( action );

Note, this example uses an Action, which implements ActionListener because Action is a newer API with addition features. For example you could disable the Action which would disable the event for both the text field and the button.

Like pretty much everyone has stated already:

A period (.) indicates a class, and a hash (#) indicates an ID.

The fundamental difference between is that you can reuse a class on your page over and over, whereas an ID can be used once. That is, of course, if you are sticking to WC3 standards.

A page will still render if you have multiple elements with the same ID, but you will run into problems if/when you try to dynamically update said elements by calling them with their ID, since they are not unique.

It is also useful to note that ID properties will supersede class properties.

Regex if you want to ensure URL starts with HTTP/HTTPS:

https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)

If you do not require HTTP protocol:

[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)

To try this out see http://regexr.com?37i6s, or for a version which is less restrictive http://regexr.com/3e6m0.

Example JavaScript implementation:

var expression = /[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)?/gi;_x000D_
var regex = new RegExp(expression);_x000D_
var t = 'www.google.com';_x000D_
_x000D_
if (t.match(regex)) {_x000D_
  alert("Successful match");_x000D_
} else {_x000D_
  alert("No match");_x000D_
}

I just put the driver files directly into my project to not get any dependency to my local machine.

final File file = new File("driver/chromedriver_2_22_mac");
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());

driver = new ChromeDriver();

You can use http://www.fontsquirrel.com/fontface/generator to encode any font for websites. It'll generate the code to include the font.

I don't really use it for fonts over 30px. They look much better as an image (because images are anti-aliased, and some browsers don't anti-alias fonts in the browser).

See: http://www.truetype-typography.com/ttalias.htm

Hope that helps...

This table shows the difference. protected internal is the same as protected, except it also allows access from other classes in the same assembly.

I need to give my user a web interface to change the session timeout interval. So, different installations of the web application would be able to have different timeouts for their sessions, but their web.xml cannot be different.

your question is simple, you need session timeout interval should be configurable at run time and configuration should be done through web interface and there shouldn't be overhead of restarting the server.

I am extending Michaels answer to address your question.

Logic: You need to store configured value in either .properties file or to database. On server start read that stored value and copy to a variable use that variable until server is UP. As config is updated update variable also. Thats it.

Expaination

In MyHttpSessionListener class 1. create a static variable with name globalSessionTimeoutInterval.

2. create a static block(executed for only for first time of class is being accessed) and read timeout value from config.properties file and set value to globalSessionTimeoutInterval variable.

3. Now use that value to set maxInactiveInterval

4. Now Web part i.e, Admin configuration page

   a. Copy configured value to static variable globalSessionTimeoutInterval.

   b. Write same value to config.properties file. (consider server is restarted then globalSessionTimeoutInterval will be loaded with value present in config.properties file)

5. Alternative .properties file OR storing it into database. Choice is yours.

Logical code for achieving the same

public class MyHttpSessionListener implements HttpSessionListener 
{
  public static Integer globalSessionTimeoutInterval = null;

  static
  {
      globalSessionTimeoutInterval =  Read value from .properties file or database;
  }
  public void sessionCreated(HttpSessionEvent event)
  {
      event.getSession().setMaxInactiveInterval(globalSessionTimeoutInterval);
  }

  public void sessionDestroyed(HttpSessionEvent event) {}

}

And in your Configuration Controller or Configuration servlet

String valueReceived = request.getParameter(timeoutValue);
if(valueReceived  != null)
{
    MyHttpSessionListener.globalSessionTimeoutInterval = Integer.parseInt(timeoutValue);
          //Store valueReceived to config.properties file or database
}

The decompiler of IntelliJ IDEA was not built with this kind of usage in mind. It is only meant to help programmers peek at the bytecode of the java classes that they are developing. For decompiling lots of class files of which you do not have source code, you will need some other java decompiler, which is specialized for this job, and most likely runs standalone. If you google you should find a bunch.

Yes, you can easily make ls output one filename per line:

ls -a | cat

Explanation: The command ls senses if the output is to a terminal or to a file or pipe and adjusts accordingly.

So, if you pipe ls -a to python it should work without any special measures.

Android Context has the following method:

public abstract boolean deleteFile (String name)

I believe this will do what you want with the right App premissions as listed above.

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

echo Hello > \\.\pipe\PipeName

When you post that data, it is stored as an array in $_POST.

You could optionally do something like:

<input name="arrayname[item1]">
<input name="arrayname[item2]">
<input name="arrayname[item3]">

Then:

$item1 = $_POST['arrayname']['item1'];
$item2 = $_POST['arrayname']['item2'];
$item3 = $_POST['arrayname']['item3'];

But I fail to see the point.

std::atan2 allows calculating the arctangent of all four quadrants. std::atan only allows calculating from quadrants 1 and 4.

The return statement you have is stuck in the inner function, so it won't return from the outer function. You just need a little more code:

function getMachine(color, qty) {
    var returnValue = null;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            returnValue = thisArray[3];
            return false; // this breaks out of the each
        }
    });
    return returnValue;
}

var retval = getMachine(color, qty);

Existing code is working, but is blocking the thread.

.Select(async ev => await ProcessEventAsync(ev))

creates a new Task for every event, but

.Select(t => t.Result)

blocks the thread waiting for each new task to end.

In the other hand your code produce the same result but keeps asynchronous.

Just one comment on your first code. This line

var tasks = await Task.WhenAll(events...

will produce a single Task<TResult[]> so the variable should be named in singular.

Finally your last code make the same but is more succinct.

For reference: Task.Wait / Task.WhenAll

Since vertical-align works as expected on a td, you could put a single celled table in the div to align its content.

<div>
    <table style="width: 100%; height: 100%;"><tr><td style="vertical-align: middle; text-align: center">
        Aligned content here...
    </td></tr></table>
</div>

Clunky, but works as far as I can tell. It might not have the drawbacks of the other workarounds.

 public static <E> E[] arrayListToTypedArray(List<E> list) {

    if (list == null) {
      return null;
    }
    int noItems = list.size();
    if (noItems == 0) {
      return null;
    }

    E[] listAsTypedArray;
    E typeHelper = list.get(0);

    try {
      Object o = Array.newInstance(typeHelper.getClass(), noItems);
      listAsTypedArray = (E[]) o;
      for (int i = 0; i < noItems; i++) {
        Array.set(listAsTypedArray, i, list.get(i));
      }
    } catch (Exception e) {
      return null;
    }

    return listAsTypedArray;
  }

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

I was trying to run node on virtual machine (vagrant) shared folder. That was a problem. My host machine is Windows, installed node on Windows and worked like a charm. So if you are using virtual machine, just try to run node server on host machine.

This will test if strings are made up of some combination or digits, the dollar sign, and a commas. Is that what you're looking for?

import re

s1 = 'Testing string'
s2 = '1234,12345$'

regex = re.compile('[0-9,$]+$')

if ( regex.match(s1) ):
   print "s1 matched"
else:
   print "s1 didn't match"

if ( regex.match(s2) ):
   print "s2 matched"
else:
   print "s2 didn't match"

I just added an @ symbol and it started working. Like this: @$product->save();

Also you should note that if your project is consist of several modules which are dependent on each other, you should use "install" instead of "package", otherwise your build will fail, cause when you use install command, module A will be packaged and deployed to local repository and then if module B needs module A as a dependency, it can access it from local repository.

The accepted answer is great. I wanted to look at what happens to the Angular scope in the context of ng-repeat. The thing is, Angular will create a sub-scope for each repeated item. When calling into a method defined on the original $scope, that retains its original value (due to javascript closure). However, the this refers the calling scope/object. This works out well, so long as you're clear on when $scope and this are the same and when they are different. hth

Here is a fiddle that illustrates the difference: https://jsfiddle.net/creitzel/oxsxjcyc/

You wrote that format can change from YYYY-mm-dd to dd-mm-YYYY you can try to find year there

$parts = explode("-","2068-06-15");
for ($i = 0; $i < count($parts); $i++)
{
     if(strlen($parts[$i]) == 4)
     {
          $year = $parts[$i];
          break;
      }
  }

To run or convert batch files externally from PowerShell (particularly if you wish to sign all your scheduled task scripts with a certificate) I simply create a PowerShell script, e.g. deletefolders.ps1.

Input the following into the script:

cmd.exe /c "rd /s /q C:\#TEMP\test1"

cmd.exe /c "rd /s /q C:\#TEMP\test2"

cmd.exe /c "rd /s /q C:\#TEMP\test3"

*Each command needs to be put on a new line calling cmd.exe again.

This script can now be signed and run from PowerShell outputting the commands to command prompt / cmd directly.

It is a much safer way than running batch files!

You should not rely on instruments -s. The officially supported tool for working with Simulators from the command line is xcrun simctl.

The log directory for a device can be found with xcrun simctl getenv booted SIMULATOR_LOG_ROOT. This will always be correct even if the location changes.

Now that things are moving to os_log it is easier to open Console.app on the host Mac. Booted simulators should show up as a log source on the left, just like physical devices. You can also run log commands in the booted simulator:

# os_log equivalent of tail -f
xcrun simctl spawn booted log stream --level=debug

# filter log output
xcrun simctl spawn booted log stream --predicate 'processImagePath endswith "myapp"'
xcrun simctl spawn booted log stream --predicate 'eventMessage contains "error" and messageType == info'

# a log dump that Console.app can open
xcrun simctl spawn booted log collect

# open location where log collect will write the dump
cd `xcrun simctl getenv booted SIMULATOR_SHARED_RESOURCES_DIRECTORY`

If you want to use Safari Developer tools (including the JS console) with a webpage in the Simulator: Start one of the simulators, open Safari, then go to Safari on your mac and you should see Simulator in the menu.

You can open a URL in the Simulator by dragging it from the Safari address bar and dropping on the Simulator window. You can also use xcrun simctl openurl booted <url>.

This is the very best explanation of automatic semicolon insertion that I've found anywhere. It will clear away all your uncertainty and doubt.

It is much easier (and possibly even faster) to script out your database, then just drop and create it from the script.

Open (and close!) your PHP tags right after, and before, your textarea tags:

<textarea style="width:350px; height:80px;" cols="42" rows="5" name="sitelink"><?php
  if($siteLink_val) echo $siteLink_val;
?></textarea>

Well, there is a lot of taste in this one. I think people from a C background are more likely to prefer for(;;), which reads as "forever". If its for work, do what the locals do, if its for yourself, do the one that you can most easily read.

But in my experience, do { } while (1); is almost never used.

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

Swift Answer

This is meant to supplement my Objective-C answer for Swift users, to keep the Objective-C answer from getting too big.

Setup

First, set up the in-app purchase on appstoreconnect.apple.com. Follow the beginning part of my Objective-C answer (steps 1-13, under the App Store Connect header) for instructions on doing that.

It could take a few hours for your product ID to register in App Store Connect, so be patient.

Now that you've set up your in-app purchase information on App Store Connect, we need to add Apple's framework for in-app-purchases, StoreKit, to the app.

Go into your Xcode project, and go to the application manager (blue page-like icon at the top of the left bar where your app's files are). Click on your app under targets on the left (it should be the first option), then go to "Capabilities" at the top. On the list, you should see an option "In-App Purchase". Turn this capability ON, and Xcode will add StoreKit to your project.

Coding

Now, we're going to start coding!

First, make a new swift file that will manage all of your in-app-purchases. I'm going to call it IAPManager.swift.

In this file, we're going to create a new class, called IAPManager that is a SKProductsRequestDelegate and SKPaymentTransactionObserver. At the top, make sure you import Foundation and StoreKit

import Foundation
import StoreKit

public class IAPManager: NSObject, SKProductsRequestDelegate,
                         SKPaymentTransactionObserver {
}

Next, we're going to add a variable to define the identifier for our in-app purchase (you could also use an enum, which would be easier to maintain if you have multiple IAPs).

// This should the ID of the in-app-purchase you made on AppStore Connect.
// if you have multiple IAPs, you'll need to store their identifiers in
// other variables, too (or, preferably in an enum).
let removeAdsID = "com.skiplit.removeAds"

Let's add an initializer for our class next:

// This is the initializer for your IAPManager class
//
// A better, and more scaleable way of doing this
// is to also accept a callback in the initializer, and call
// that callback in places like the paymentQueue function, and
// in all functions in this class, in place of calls to functions
// in RemoveAdsManager (you'll see those calls in the code below).

let productID: String
init(productID: String){
    self.productID = productID
}

Now, we're going to add the required functions for SKProductsRequestDelegate and SKPaymentTransactionObserver to work:

_{We'll add the RemoveAdsManager class later}

// This is called when a SKProductsRequest receives a response
public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse){
    // Let's try to get the first product from the response
    // to the request
    if let product = response.products.first{
        // We were able to get the product! Make a new payment
        // using this product
        let payment = SKPayment(product: product)

        // add the new payment to the queue
        SKPaymentQueue.default().add(self)
        SKPaymentQueue.default().add(payment)
    }
    else{
        // Something went wrong! It is likely that either
        // the user doesn't have internet connection, or
        // your product ID is wrong!
        //
        // Tell the user in requestFailed() by sending an alert,
        // or something of the sort

        RemoveAdsManager.removeAdsFailure()
    }
}

// This is called when the user restores their IAP sucessfully
private func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue){
    // For every transaction in the transaction queue...
    for transaction in queue.transactions{
        // If that transaction was restored
        if transaction.transactionState == .restored{
            // get the producted ID from the transaction
            let productID = transaction.payment.productIdentifier

            // In this case, we have only one IAP, so we don't need to check
            // what IAP it is. However, this is useful if you have multiple IAPs!
            // You'll need to figure out which one was restored
            if(productID.lowercased() == IAPManager.removeAdsID.lowercased()){
                // Restore the user's purchases
                RemoveAdsManager.restoreRemoveAdsSuccess()
            }

            // finish the payment
            SKPaymentQueue.default().finishTransaction(transaction)
        }
    }
}

// This is called when the state of the IAP changes -- from purchasing to purchased, for example.
// This is where the magic happens :)
public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]){
    for transaction in transactions{
        // get the producted ID from the transaction
        let productID = transaction.payment.productIdentifier

        // In this case, we have only one IAP, so we don't need to check
        // what IAP it is.
        // However, if you have multiple IAPs, you'll need to use productID
        // to check what functions you should run here!

        switch transaction.transactionState{
        case .purchasing:
            // if the user is currently purchasing the IAP,
            // we don't need to do anything.
            //
            // You could use this to show the user
            // an activity indicator, or something like that
            break
        case .purchased:
            // the user successfully purchased the IAP!
            RemoveAdsManager.removeAdsSuccess()
            SKPaymentQueue.default().finishTransaction(transaction)
        case .restored:
                // the user restored their IAP!
                IAPTestingHandler.restoreRemoveAdsSuccess()
                SKPaymentQueue.default().finishTransaction(transaction)
        case .failed:
                // The transaction failed!
                RemoveAdsManager.removeAdsFailure()
                // finish the transaction
                SKPaymentQueue.default().finishTransaction(transaction)
        case .deferred:
                // This happens when the IAP needs an external action
                // in order to proceeded, like Ask to Buy
                RemoveAdsManager.removeAdsDeferred()
                break
        }
    }
}

Now let's add some functions that can be used to start a purchase or a restore purchases:

// Call this when you want to begin a purchase
// for the productID you gave to the initializer
public func beginPurchase(){
    // If the user can make payments
    if SKPaymentQueue.canMakePayments(){
        // Create a new request
        let request = SKProductsRequest(productIdentifiers: [productID])
        // Set the request delegate to self, so we receive a response
        request.delegate = self
        // start the request
        request.start()
    }
    else{
        // Otherwise, tell the user that
        // they are not authorized to make payments,
        // due to parental controls, etc
    }
}

// Call this when you want to restore all purchases
// regardless of the productID you gave to the initializer
public func beginRestorePurchases(){
    // restore purchases, and give responses to self
    SKPaymentQueue.default().add(self)
    SKPaymentQueue.default().restoreCompletedTransactions()
}

Next, let's add a new utilities class to manage our IAPs. All of this code could be in one class, but having it multiple makes it a little cleaner. I'm going to make a new class called RemoveAdsManager, and in it, put a few functions

public class RemoveAdsManager{

    class func removeAds()
    class func restoreRemoveAds()

    class func areAdsRemoved() -> Bool

    class func removeAdsSuccess()
    class func restoreRemoveAdsSuccess()
    class func removeAdsDeferred()
    class func removeAdsFailure()
}

The first three functions, removeAds, restoreRemoveAds, and areAdsRemoved, are functions that you'll call to do certain actions. The last four are one that will be called by IAPManager.

Let's add some code to the first two functions, removeAds and restoreRemoveAds:

// Call this when the user wants
// to remove ads, like when they
// press a "remove ads" button
class func removeAds(){
    // Before starting the purchase, you could tell the
    // user that their purchase is happening, maybe with
    // an activity indicator

    let iap = IAPManager(productID: IAPManager.removeAdsID)
    iap.beginPurchase()
}

// Call this when the user wants
// to restore their IAP purchases,
// like when they press a "restore
// purchases" button.
class func restoreRemoveAds(){
    // Before starting the purchase, you could tell the
    // user that the restore action is happening, maybe with
    // an activity indicator

    let iap = IAPManager(productID: IAPManager.removeAdsID)
    iap.beginRestorePurchases()
}

And lastly, let's add some code to the last five functions.

// Call this to check whether or not
// ads are removed. You can use the
// result of this to hide or show
// ads
class func areAdsRemoved() -> Bool{
    // This is the code that is run to check
    // if the user has the IAP.

    return UserDefaults.standard.bool(forKey: "RemoveAdsPurchased")
}

// This will be called by IAPManager
// when the user sucessfully purchases
// the IAP
class func removeAdsSuccess(){
    // This is the code that is run to actually
    // give the IAP to the user!
    //
    // I'm using UserDefaults in this example,
    // but you may want to use Keychain,
    // or some other method, as UserDefaults
    // can be modified by users using their
    // computer, if they know how to, more
    // easily than Keychain

    UserDefaults.standard.set(true, forKey: "RemoveAdsPurchased")
    UserDefaults.standard.synchronize()
}

// This will be called by IAPManager
// when the user sucessfully restores
//  their purchases
class func restoreRemoveAdsSuccess(){
    // Give the user their IAP back! Likely all you'll need to
    // do is call the same function you call when a user
    // sucessfully completes their purchase. In this case, removeAdsSuccess()

    removeAdsSuccess()
}

// This will be called by IAPManager
// when the IAP failed
class func removeAdsFailure(){
    // Send the user a message explaining that the IAP
    // failed for some reason, and to try again later
}

// This will be called by IAPManager
// when the IAP gets deferred.
class func removeAdsDeferred(){
    // Send the user a message explaining that the IAP
    // was deferred, and pending an external action, like
    // Ask to Buy.
}

Putting it all together, we get something like this:

import StoreKit

public class RemoveAdsManager{

    // Call this when the user wants
    // to remove ads, like when they
    // press a "remove ads" button

        // user that their purchase is happening, maybe with
        // an activity indicator

        let iap = IAPManager(productID: IAPManager.removeAdsID)
        iap.beginPurchase()
    }

    // Call this when the user wants
    // to restore their IAP purchases,
    // like when they press a "restore
    // purchases" button.
    class func restoreRemoveAds(){
        // Before starting the purchase, you could tell the
        // user that the restore action is happening, maybe with
        // an activity indicator

        let iap = IAPManager(productID: IAPManager.removeAdsID)
        iap.beginRestorePurchases()
    }

    // Call this to check whether or not

        return UserDefaults.standard.bool(forKey: "RemoveAdsPurchased")
    }

                // we don't need to do anything.
                //
                // You could use this to show the user

                break
            case .purchased:
                // the user sucessfully purchased the IAP!
                RemoveAdsManager.removeAdsSuccess()
                SKPaymentQueue.default().finishTransaction(transaction)

                SKPaymentQueue.default().finishTransaction(transaction)
            case .failed:
                // The transaction failed!

                // in order to proceeded, like Ask to Buy
                RemoveAdsManager.removeAdsDeferred()
                break
            }
        }
    }

}

Lastly, you need to add some way for the user to start the purchase and call RemoveAdsManager.removeAds() and start a restore and call RemoveAdsManager.restoreRemoveAds(), like a button somewhere! Keep in mind that, per the App Store guidelines, you do need to provide a button to restore purchases somewhere.

Submitting for review

The last thing to do is submit your IAP for review on App Store Connect! For detailed instructions on doing that, you can follow the last part of my Objective-C answer, under the Submitting for review header.

The straightforward way to do this correctly and securely is to use Open3.capture2(), Open3.capture2e(), or Open3.capture3().

Using ruby's backticks and its %x alias are NOT SECURE UNDER ANY CIRCUMSTANCES if used with untrusted data. It is DANGEROUS, plain and simple:

untrusted = "; date; echo"
out = `echo #{untrusted}`                              # BAD

untrusted = '"; date; echo"'
out = `echo "#{untrusted}"`                            # BAD

untrusted = "'; date; echo'"
out = `echo '#{untrusted}'`                            # BAD

The system function, in contrast, escapes arguments properly if used correctly:

ret = system "echo #{untrusted}"                       # BAD
ret = system 'echo', untrusted                         # good

Trouble is, it returns the exit code instead of the output, and capturing the latter is convoluted and messy.

The best answer in this thread so far mentions Open3, but not the functions that are best suited for the task. Open3.capture2, capture2e and capture3 work like system, but returns two or three arguments:

out, err, st = Open3.capture3("echo #{untrusted}")     # BAD
out, err, st = Open3.capture3('echo', untrusted)       # good
out_err, st  = Open3.capture2e('echo', untrusted)      # good
out, st      = Open3.capture2('echo', untrusted)       # good
p st.exitstatus

Another mentions IO.popen(). The syntax can be clumsy in the sense that it wants an array as input, but it works too:

out = IO.popen(['echo', untrusted]).read               # good

For convenience, you can wrap Open3.capture3() in a function, e.g.:

#
# Returns stdout on success, false on failure, nil on error
#
def syscall(*cmd)
  begin
    stdout, stderr, status = Open3.capture3(*cmd)
    status.success? && stdout.slice!(0..-(1 + $/.size)) # strip trailing eol
  rescue
  end
end

Example:

p system('foo')
p syscall('foo')
p system('which', 'foo')
p syscall('which', 'foo')
p system('which', 'which')
p syscall('which', 'which')

Yields the following:

nil
nil
false
false
/usr/bin/which         <— stdout from system('which', 'which')
true                   <- p system('which', 'which')
"/usr/bin/which"       <- p syscall('which', 'which')

Edit /etc/sudoers file either manually or using the visudo application. Remember: System reads /etc/sudoers file from top to the bottom, so you could overwrite a particular setting by putting the next one below. So to be on the safe side - define your access setting at the bottom.

WMIC

wmic is a very complete tool

wmic diskdrive list

provide a (too much) detailed list, for instance

for less info

wmic diskdrive list brief 

C

Sebastian Godelet mentions in the comments:

In C:

system("wmic diskdrive list");

As commented, you can also call the WinAPI, but... as shown in "How to obtain data from WMI using a C Application?", this is quite complex (and generally done with C++, not C).

PowerShell

Or with PowerShell:

Get-WmiObject Win32_DiskDrive

In addition to above answers,

Just make sure you set estimatedItemSize property of UICollectionViewFlowLayout to some size and do not implement sizeForItem:atIndexPath delegate method.

That's it.

To get the fields info too, you can use the following:

SELECT TABLE_SCHEMA, TABLE_NAME, 
       COLUMN_NAME, substring(DATA_TYPE, 1,1) AS DATA_TYPE
FROM information_schema.COLUMNS 
WHERE TABLE_SCHEMA NOT IN("information_schema", "mysql", "performance_schema") 
ORDER BY TABLE_SCHEMA, TABLE_NAME, ORDINAL_POSITION

If you are using Query builder then you may use a blow

DB::table(Newsletter Subscription)
->select('*')
->whereIn('id', $send_users_list)
->get()

If you are working with Eloquent then you can use as below

$sendUsersList = Newsletter Subscription:: select ('*')
                ->whereIn('id', $send_users_list)
                ->get();

constructor(
 public sanitizer: DomSanitizer, ) {

 }

I had been struggling for 4 hours. the problem was in img tag. When you use square bracket to 'src' ex: [src]. you can not use this angular expression {{}}. you just give directly from an object example below. if you give angular expression {{}}. you will get interpolation error.

1. first i used ngFor to iterate the countries

   *ngFor="let country of countries"
   

2. second you put this in the img tag. this is it.

   <img [src]="sanitizer.bypassSecurityTrustResourceUrl(country.flag)"
   height="20" width="20" alt=""/>
   

ActiveModel::Dirty didn't work for me because the @model.update_attributes() hid the changes. So this is how I detected changes it in an update method in a controller:

def update
  @model = Model.find(params[:id])
  detect_changes

  if @model.update_attributes(params[:model])
    do_stuff if attr_changed?
  end
end

private

def detect_changes
  @changed = []
  @changed << :attr if @model.attr != params[:model][:attr]
end

def attr_changed?
  @changed.include :attr
end

If you're trying to detect a lot of attribute changes it could get messy though. Probably shouldn't do this in a controller, but meh.

SOAPAction is required in SOAP 1.1 but can be empty ("").

See https://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383528

"The header field value of empty string ("") means that the intent of the SOAP message is provided by the HTTP Request-URI."

Try setting SOAPAction=""

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

Store the return of setInterval in a variable, and use it later to clear the interval.

var timer = null;
$("textarea").blur(function(){
    timer = window.setInterval(function(){ ... whatever ... }, 2000);
}).focus(function(){
    if(timer){
       window.clearInterval(timer);
       timer = null
    }
});

React Router V5

If you want the pathName as a string ('/' or 'users'), you can use the following:

  // React Hooks: React Router DOM
  let history = useHistory();
  const location = useLocation();
  const pathName = location.pathname;

Why don't you try to grep the return of your command ? Something like :

adb devices -l | grep 123abc12

It should return only the line you want to.

My solution is to simply use ViewPager widget. It isn't center-locked as Gallery and has a built-in features for recycling views (as ListView). You may see similar approach at Google Play app, whenever you deal with horizontally scrollable lists.

You just need to extend PagerAdapter and perform a couple of tweaks there:

public class MyPagerAdapter extends PagerAdapter {

    private Context mContext;

    public MyPagerAdapter(Context context) {
        this.mContext = context;
    }

    // As per docs, you may use views as key objects directly 
    // if they aren't too complex
    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        View view = inflater.inflate(R.layout.item, null);
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public int getCount() {
        return 10;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }

    // Important: page takes all available width by default,
    // so let's override this method to fit 5 pages within single screen
    @Override
    public float getPageWidth(int position) {
        return 0.2f;
    }
}

As result, you'll have horizontally scrollable widget with adapter, like this:

HTML

<div id='parent'>
  <div id='centered-child'></div>
</div>

CSS

#parent {
  position: relative;
}
#centered-child {
  position: absolute;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  margin: auto auto;
}

So there's another way (and it is portable to some extent_

(python <<EOF
import fnmatch
import os
import os.path as path
import time

matches = []
def find(dirname=None, newerThan=3*24*3600, olderThan=None):
    for root, dirnames, filenames in os.walk(dirname or '.'):
        for filename in fnmatch.filter(filenames, '*'):
            filepath = os.path.join(root, filename)
            matches.append(path)
            ts_now = time.time()
            newer = ts_now - path.getmtime(filepath) < newerThan
            older = ts_now - path.getmtime(filepath) > newerThan
            if newerThan and newer or olderThan and older: print filepath
    for dirname in dirnames:
        if dirname not in ['.', '..']:
            print 'dir:', dirname
            find(dirname)
find('.')
EOF
) | xargs -I '{}' echo found file modified within 3 days '{}'

There are two project types in VS for ASP.NET projects:

Web Application Projects (which notably have a .csproj or .vbproj file to store these settings) have a Properties node under the project. On the Web tab, you can configure the Project URL (assuming IIS Express or IIS) to use whatever port you want, and just click the Create Virtual Directory button. These settings are saved to the project file:

<ProjectExtensions>
  <VisualStudio>
    <FlavorProperties GUID="{349c5851-65df-11da-9384-00065b846f21}">
      <WebProjectProperties>
       <DevelopmentServerPort>10531</DevelopmentServerPort>
       ...
     </WebProjectProperties>
    </FlavorProperties>
  </VisualStudio>
</ProjectExtensions>

Web Site Projects are different. They don't have a .*proj file to store settings in; instead, the settings are set in the solution file. In VS2013, the settings look something like this:

Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "WebSite1(1)", "http://localhost:10528", "{401397AC-86F6-4661-A71B-67B4F8A3A92F}"
    ProjectSection(WebsiteProperties) = preProject
        UseIISExpress = "true"
        TargetFrameworkMoniker = ".NETFramework,Version%3Dv4.5"
        ...
        SlnRelativePath = "..\..\WebSites\WebSite1\"
        DefaultWebSiteLanguage = "Visual Basic"
    EndProjectSection
EndProject

Because the project is identified by the URL (including port), there isn't a way in the VS UI to change this. You should be able to modify the solution file though, and it should work.

Jsut an FYI, if you're using jQuery you have

$.isNumeric() 

to handle this. More details on http://api.jquery.com/jQuery.isNumeric/

Here is the syntax to create a trigger:

CREATE TRIGGER trigger_name
ON { table | view }
[ WITH ENCRYPTION ]
{
    { { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] }
        [ WITH APPEND ]
        [ NOT FOR REPLICATION ]
        AS
        [ { IF UPDATE ( column )
            [ { AND | OR } UPDATE ( column ) ]
                [ ...n ]
        | IF ( COLUMNS_UPDATED ( ) { bitwise_operator } updated_bitmask )
                { comparison_operator } column_bitmask [ ...n ]
        } ]
        sql_statement [ ...n ]
    }
} 

If you want to use On Update you only can do it with the IF UPDATE ( column ) section. That's not possible to do what you are asking.

If you want to avoid including the full path to awk, you need to update your PATH variable to include the path to the directory where awk is located, then you can just type

From Jackson 2.5, an elegant way to solve that is using the TypeFactory.constructParametricType(Class parametrized, Class... parameterClasses) method that allows to define straigthly a Jackson JavaType by specifying the parameterized class and its parameterized types.

Supposing you want to deserialize to Data<String>, you can do :

// the json variable may be a String, an InputStream and so for...
JavaType type = mapper.getTypeFactory().constructParametricType(Data.class, String.class);
Data<String> data = mapper.readValue(json, type);

Note that if the class declared multiple parameterized types, it would not be really harder :

class Data <T, U> {
    int found;
    Class<T> hits;
    List<U> list;
}

We could do :

JavaType type = mapper.getTypeFactory().constructParametricType(Data.class, String.class, Integer);
Data<String, Integer> data = mapper.readValue(json, type);

Might be a problem with date configuration on server side or on client side. I've found this to be a common problem on multiple databases when the host is configured in spanish, french or whatever... that could affect the format dd/mm/yyyy or mm/dd/yyyy.

You could also do this:

#!/usr/bin/perl

use strict;
use warnings;

$^I = '.bak'; # create a backup copy 

while (<>) {
   s/<PREF>/ABCD/g; # do the replacement
   print; # print to the modified file
}

Invoke the script with by

./script.pl input_file

You will get a file named input_file, containing your changes, and a file named input_file.bak, which is simply a copy of the original file.

It is bad practice to throw Exception, as that requires anyone who calls your constructor to catch Exception which is a bad practice.

It is a good idea to have a constructor (or any method) throw an exception, generally speaking IllegalArgumentException, which is unchecked, and thus the compiler doesn't force you to catch it.

You should throw checked exceptions (things that extend from Exception, but not RuntimeException) if you want the caller to catch it.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

syntax of date_format:

SELECT date_format(date_born, '%m/%d/%Y' ) as my_date FROM date_tbl

    '%W %D %M %Y %T'    -> Wednesday 5th May 2004 23:56:25
    '%a %b %e %Y %H:%i' -> Wed May 5 2004 23:56
    '%m/%d/%Y %T'       -> 05/05/2004 23:56:25
    '%d/%m/%Y'          -> 05/05/2004
    '%m-%d-%y'          -> 04-08-13

I'm more interested in knowing if there is a built-in framework method that will parse directly into a nullable int?

There isn't.

In your activity class:

public class BasicActivity extends Activity {

private ComplexObject co;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_page);

    co=new ComplexObject();
    getIntent().putExtra("complexObject", co);

    FragmentManager fragmentManager = getFragmentManager();
    Fragment1 f1 = new Fragment1();
    fragmentManager.beginTransaction()
            .replace(R.id.frameLayout, f1).commit();

}

Note: Your object should implement Serializable interface

Then in your fragment :

public class Fragment1 extends Fragment {

ComplexObject co;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    Intent i = getActivity().getIntent();

    co = (ComplexObject) i.getSerializableExtra("complexObject");

    View view = inflater.inflate(R.layout.test_page, container, false);
    TextView textView = (TextView) view.findViewById(R.id.DENEME);
    textView.setText(co.getName());

    return view;
}
}

You can also try:

 > npm run ng <command>

The existing answers explain the problem well but if including your script files using or before requireJS is not an easy option due to legacy code a slightly hacky workaround is to remove require from the window scope before your script tag and then reinstate it afterwords. In our project this is wrapped behind a server-side function call but effectively the browser sees the following:

    <script>
        window.__define = window.define;
        window.__require = window.require;
        window.define = undefined;
        window.require = undefined;
    </script>
    <script src="your-script-file.js"></script>        
    <script>
        window.define = window.__define;
        window.require = window.__require;
        window.__define = undefined;
        window.__require = undefined;
    </script>

Not the neatest but seems to work and has saved a lot of refractoring.

width:200px;
white-space: nowrap;
text-overflow: ellipsis;
overflow: hidden;

Define width also to set overflow in one line

Don't forget to bring your Panel to the Front when dynamically creating it in the form constructor. Example of transparent panel overlay of tab control.

panel1 = new TransparentPanel();
panel1.BackColor = System.Drawing.Color.Transparent;
panel1.Location = new System.Drawing.Point(0, 0);
panel1.Name = "panel1";
panel1.Size = new System.Drawing.Size(717, 92);
panel1.TabIndex = 0;
tab2.Controls.Add(panel1);
panel1.BringToFront(); 

// <== otherwise the other controls paint over top of the transparent panel

If you want to get the file names only without the rest of the commit message you can use:

git log --name-only --pretty=format: <branch name>

This can then be extended to use the various options that contain the file name:

git log --name-status --pretty=format: <branch name>

git log --stat --pretty=format: <branch name>

One thing to note when using this method is that there are some blank lines in the output that will have to be ignored. Using this can be useful if you'd like to see the files that have been changed on a local branch, but is not yet pushed to a remote branch and there is no guarantee the latest from the remote has already been pulled in. For example:

git log --name-only --pretty=format: my_local_branch --not origin/master

Would show all the files that have been changed on the local branch, but not yet merged to the master branch on the remote.

Rather than this expression to create a POSIX timestamp from dt,

(dt - datetime(1970,1,1)).total_seconds()

Use this:

int(dt.strftime("%s"))

I get the right answer in your example using the second method.

EDIT: Some followup... After some comments (see below), I was curious about the lack of support or documentation for %s in strftime. Here's what I found:

In the Python source for datetime and time, the string STRFTIME_FORMAT_CODES tells us:

"Other codes may be available on your platform.
 See documentation for the C library strftime function."

So now if we man strftime (on BSD systems such as Mac OS X), you'll find support for %s:

"%s is replaced by the number of seconds since the Epoch, UTC (see mktime(3))."

Anyways, that's why %s works on the systems it does. But there are better solutions to OP's problem (that take timezones into account). See @abarnert's accepted answer here.

Gradle 4.9+

gradle run --args='arg1 arg2'

This assumes your build.gradle is configured with the Application plugin. Your build.gradle should look similar to this:

plugins {
  // Implicitly applies Java plugin
  id: 'application'
}

application {
  // URI of your main class/application's entry point (required)
  mainClassName = 'org.gradle.sample.Main'
}

Pre-Gradle 4.9

Include the following in your build.gradle:

run {
    if (project.hasProperty("appArgs")) {
        args Eval.me(appArgs)
    }
}

Then to run: gradle run -PappArgs="['arg1', 'args2']"

For those searching for the inverse of this, i.e. looking for tables that do not contain a certain column name, here is the query...

SELECT DISTINCT TABLE_NAME FROM information_schema.columns WHERE 
TABLE_SCHEMA = 'your_db_name' AND TABLE_NAME NOT IN (SELECT DISTINCT 
TABLE_NAME FROM information_schema.columns WHERE column_name = 
'column_name' AND TABLE_SCHEMA = 'your_db_name');

This came in really handy when we began to slowly implement use of InnoDB's special ai_col column and needed to figure out which of our 200 tables had yet to be upgraded.

Easy way, use type="number" if it works for your use case:

<input type="number" ng-model="myText" name="inputName">

Another easy way: ng-pattern can also be used to define a regex that will limit what is allowed in the field. See also the "cookbook" page about forms.

Hackish? way, $watch the ng-model in your controller:

<input type="text"  ng-model="myText" name="inputName">

Controller:

$scope.$watch('myText', function() {
   // put numbersOnly() logic here, e.g.:
   if ($scope.myText  ... regex to look for ... ) {
      // strip out the non-numbers
   }
})

Best way, use a $parser in a directive. I'm not going to repeat the already good answer provided by @pkozlowski.opensource, so here's the link: https://stackoverflow.com/a/14425022/215945

All of the above solutions involve using ng-model, which make finding this unnecessary.

Using ng-change will cause problems. See AngularJS - reset of $scope.value doesn't change value in template (random behavior)

Create a separate ul.nav for just that list item and float that ul right.

Put quotes around the <?php echo $cname; ?> to make sure Javascript accepts it as a string, also consider escaping.

In addition to the accepted answer (the project is on Flutter but it's basically the same as native):

I do have folders Base.lproj, en.lproj, xx.kproj. etc. with InfoPlist.strings in each. This file has lines like this (no quotes around the key and with a semicolon at the end):

NSLocationWhenInUseUsageDescription = "My explanation why I need this";

Check that you have your languages in your YourProject > Info:

Also, check the project.pbxproj file, it is in XXX.xcodeproj/project.pbxproj: it should have all your languages in codes (en, fr, etc.)

But even then it didn't work. Finally, I noticed the CFBundleLocalizations key in the Info.plist file. (to open it as raw key-values in XCode - right mouse button on the Info.plist file -> Open As -> Source Code) Make sure that the values in array are codes rather than complete words, for example fr instead of French etc.

<key>CFBundleLocalizations</key>
<array>
    <string>en</string>
    <string>ru</string>
    <string>lv</string>
</array>

And double-check that your device is set to the language you're testing. Cheers

P.S. "Development Language" doesn't affect your issue, don't bother changing it.

You can search a directory using Find ? Find in files. This also includes all opened tabs.

The keyboard shortcut is Ctrl?+F on non-Mac (regular) keyboards, and ??+F on a Mac.

You'll be presented with three boxes: Find, Where and Replace. It's a regular Find/Find-replace search where Where specifies a file or directory to search. I for example often use a file name or . for searching the current directory. There are also a few special constructs that can be used within the Where field:

<project>,<current file>,<open files>,<open folders>,-*.doc,*.txt

Note that these are not placeholders, you type these verbatim. Most of them are self-explanatory (e.g. -*.doc excludes files with a .doc extension).

Pressing the ... to the right will present you with all available options.

After searching you'll be presented with a Find results page with all of your matching results. To jump to specific lines and files from it you simply double-click on a line.

You can set HTML object's property checked to false like this:

document.getElementById('desiredInput').checked = false;

Example: Hold down Ctrl (? on mac) key to uncheck.

var radios = document.getElementsByTagName('input');
for(i=0; i<radios.length; i++ ) {
    radios[i].onclick = function(e) {
        if(e.ctrlKey || e.metaKey) {
            this.checked = false;
        }
    }
}

<input type="radio" name="test" value="1" />
<input type="radio" name="test" value="2" checked="checked" />
<input type="radio" name="test" value="3" />

jQuery example

There's no built-in way, you'll have to loop over all of them:

function setAll(a, v) {
    var i, n = a.length;
    for (i = 0; i < n; ++i) {
        a[i] = v;
    }
}

http://jsfiddle.net/alnitak/xG88A/

If you really want, do this:

Array.prototype.setAll = function(v) {
    var i, n = this.length;
    for (i = 0; i < n; ++i) {
        this[i] = v;
    }
};

and then you could actually do cool.setAll(42) (see http://jsfiddle.net/alnitak/ee3hb/).

Some people frown upon extending the prototype of built-in types, though.

EDIT ES5 introduced a way to safely extend both Object.prototype and Array.prototype without breaking for ... in ... enumeration:

Object.defineProperty(Array.prototype, 'setAll', {
    value: function(v) {
        ...
    }
});

EDIT 2 In ES6 draft there's also now Array.prototype.fill, usage cool.fill(42)

It might be beneficial to add greedy matching to the end of the string, so you can accept strings > than 10 and the regex will only return up to the first 10 chars. /^[a-z0-9]{0,10}$?/

The Best form to hide and show a modal with bootstrap it's

// SHOW
$('#ModalForm').modal('show');
// HIDE
$('#ModalForm').modal('hide');

What worked for me was to create a viewmodel that contained the date property as a string. Assigning the DateTime property from the domain model and calling the .ToString() on the date property while assigning the value to the viewmodel.

A JSON result from an MVC action method will return the date in a format compatible with the view.

View Model

public class TransactionsViewModel
{
    public string DateInitiated { get; set; }
    public string DateCompleted { get; set; }
}

Domain Model

public class Transaction{
   public DateTime? DateInitiated {get; set;}
   public DateTime? DateCompleted {get; set;}
}

Controller Action Method

public JsonResult GetTransactions(){

var transactions = _transactionsRepository.All;
        var model = new List<TransactionsViewModel>();

        foreach (var transaction in transactions)
        {
            var item = new TransactionsViewModel
            {
                ...............
                DateInitiated = transaction.DateInitiated.ToString(),
                DateCompleted = transaction.DateCompleted.ToString(),
            };

            model.Add(item);
        }
        return Json(model, JsonRequestBehavior.AllowGet);
}

Use of sort can result in warning message. See github discussion. So you might wanna use sort_values, docs here

Then your code can look like this:

df = df.sort_values(by=['c1','c2'], ascending=[False,True])

$this->db->select('overal_points');
$this->db->where('point_publish', 1);
$this->db->order_by('overal_points', 'desc'); 
$query = $this->db->get('company', 4)->result();

I just benchmarked a file transfer over both FTP and HTTP :

• over two very good server connections
• using the same 1GB .zip file
• under the same network conditions (tested one after the other)

The result:

• using FTP: 6 minutes
• using HTTP: 4 minutes
• using a concurrent http downloader software (fdm): 1 minute

So, basically under a "real life" situation:

1) HTTP is faster than FTP when downloading one big file.

2) HTTP can use parallel chunk download which makes it 6x times faster than FTP depending on the network conditions.

Thanks to jimhark's answer and other answers here, I found a way to do it in PowerShell:

$ProcessID = 1234
$MemberDefinition = '
    [DllImport("kernel32.dll")]public static extern bool FreeConsole();
    [DllImport("kernel32.dll")]public static extern bool AttachConsole(uint p);
    [DllImport("kernel32.dll")]public static extern bool GenerateConsoleCtrlEvent(uint e, uint p);
    public static void SendCtrlC(uint p) {
        FreeConsole();
        if (AttachConsole(p)) {
            GenerateConsoleCtrlEvent(0, p);
            FreeConsole();
        }
        AttachConsole(uint.MaxValue);
    }'
Add-Type -Name 'dummyName' -Namespace 'dummyNamespace' -MemberDefinition $MemberDefinition
[dummyNamespace.dummyName]::SendCtrlC($ProcessID) }

What made things work was sending the GenerateConsoleCtrlEvent to the desired process group instead of all processes that share the console of the calling process and AttachConsole back to the console of the parent of the current process.

chmod 400 mykey.pem

ssh -i mykey.pem [email protected]

Will connect you over ssh using a .pem file to any server.

If you have a value and want to find the key, use array_search() like this:

$arr = array ('first' => 'a', 'second' => 'b', );
$key = array_search ('a', $arr);

$key will now contain the key for value 'a' (that is, 'first').

Commenting here as this seems to be the most popular answer on the subject for searching for files whilst excluding certain directories in powershell.

To avoid issues with post filtering of results (i.e. avoiding permission issues etc), I only needed to filter out top level directories and that is all this example is based on, so whilst this example doesn't filter child directory names, it could very easily be made recursive to support this, if you were so inclined.

Quick breakdown of how the snippet works

$folders << Uses Get-Childitem to query the file system and perform folder exclusion

$file << The pattern of the file I am looking for

foreach << Iterates the $folders variable performing a recursive search using the Get-Childitem command

$folders = Get-ChildItem -Path C:\ -Directory -Name -Exclude Folder1,"Folder 2"
$file = "*filenametosearchfor*.extension"

foreach ($folder in $folders) {
   Get-Childitem -Path "C:/$folder" -Recurse -Filter $file | ForEach-Object { Write-Output $_.FullName }
}

You can just use sum(people$Weight).

sum sums up a vector, and people$Weight retrieves the weight column from your data frame.

Note - you can get built-in help by using ?sum, ?colSums, etc. (by the way, colSums will give you the sum for each column).

Try this:

UITextField *theTextFiels=[[UITextField alloc]initWithFrame:CGRectMake(40, 40, 150, 30)];
    theTextFiels.borderStyle=UITextBorderStyleNone;
    theTextFiels.layer.cornerRadius=8.0f;
    theTextFiels.layer.masksToBounds=YES;
        theTextFiels.backgroundColor=[UIColor redColor];
    theTextFiels.layer.borderColor=[[UIColor blackColor]CGColor];
    theTextFiels.layer.borderWidth= 1.0f;

    [self.view addSubview:theTextFiels];
    [theTextFiels release];

and import QuartzCore:

#import <QuartzCore/QuartzCore.h>

No, in C++ you cannot call a constructor from a constructor. What you can do, as warren pointed out, is:

• Overload the constructor, using different signatures
• Use default values on arguments, to make a "simpler" version available

Note that in the first case, you cannot reduce code duplication by calling one constructor from another. You can of course have a separate, private/protected, method that does all the initialization, and let the constructor mainly deal with argument handling.

just paste this code <add key="owin:AutomaticAppStartup" value="false" /> in Web.config Not In web.config there is two webconfig so be sure that it will been paste in Web.Config

A live example of using php curl_exec to do an HTTP post:

Put this in a file called foobar.php:

<?php
  $ch = curl_init();
  $skipper = "luxury assault recreational vehicle";
  $fields = array( 'penguins'=>$skipper, 'bestpony'=>'rainbowdash');
  $postvars = '';
  foreach($fields as $key=>$value) {
    $postvars .= $key . "=" . $value . "&";
  }
  $url = "http://www.google.com";
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_POST, 1);                //0 for a get request
  curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,3);
  curl_setopt($ch,CURLOPT_TIMEOUT, 20);
  $response = curl_exec($ch);
  print "curl response is:" . $response;
  curl_close ($ch);
?>

Then run it with the command php foobar.php, it dumps this kind of output to screen:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" 
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Title</title>

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">
<body>
  A mountain of content...
</body>
</html>

So you did a PHP POST to www.google.com and sent it some data.

Had the server been programmed to read in the post variables, it could decide to do something different based upon that.

This is very straightforward with boolean arrays:

p31 = numpy.asarray(o31)
za = (p31 < 200).sum() # p31<200 is a boolean array, so `sum` counts the number of True elements

In Elegoo Super Starter Kit, Part 2, Lesson 2.12, IR Receiver Module, I hit the problem that the lesson's IRremote library has a hard conflict with the built-in Arduino RobotIRremote library. I am using the Win10 IDE App, and it was non-trivial to "move the RobotIRremote" folder like the pre-Win10 instructions said. The built-in Libraries are saved at a path like: C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.42.0_x86__mdqgnx93n4wtt\libraries You won't be able to see WindowsApps unless you show hidden files, and you can't do anything in that folder structure until you are the owner. Carefully follow these directions to make that happen: https://www.youtube.com/watch?v=PmrOzBDZTzw
After hours of frustration, the process above finally resulted in success for me. Elegoo gets an F+ for modern instructions on this lesson.

You can convert a datetime.date object into a pandas Timestamp like this:

#!/usr/bin/env python3
# coding: utf-8

import pandas as pd
import datetime

# create a datetime data object
d_time = datetime.date(2010, 11, 12)

# create a pandas Timestamp object
t_stamp = pd.to_datetime('2010/11/12')

# cast `datetime_timestamp` as Timestamp object and compare
d_time2t_stamp = pd.to_datetime(d_time)

# print to double check
print(d_time)
print(t_stamp)
print(d_time2t_stamp)

# since the conversion succeds this prints `True`
print(d_time2t_stamp == t_stamp)

As noone posted the code that uses BitConverter and actually checks the endianness, here goes:

byte[] ip = address.Split('.').Select(s => Byte.Parse(s)).ToArray();
if (BitConverter.IsLittleEndian) {
  Array.Reverse(ip);
}
int num = BitConverter.ToInt32(ip, 0);

and back:

byte[] ip = BitConverter.GetBytes(num);
if (BitConverter.IsLittleEndian) {
  Array.Reverse(ip);
}
string address = String.Join(".", ip.Select(n => n.ToString()));

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

Try replaceAll() method of the String class.

BTW here is the method, return type and parameters.

public String replaceAll(String regex,

Example:

String str = "Hello +-^ my + - friends ^ ^^-- ^^^ +!";
str = str.replaceAll("[-+^]*", "");

It should remove all the {'^', '+', '-'} chars that you wanted to remove!

You can use TEXT like this as part of a concatenation

=TEXT(A1,"dd-mmm-yy") & " other string"

Old question, but I should note that the general task of parsing XLS files from javascript is tedious and difficult but not impossible.

I have basic parsers implemented in pure JS:

• http://oss.sheetjs.com/js-xls/ (XLS files, what you wanted)
• http://oss.sheetjs.com/js-xlsx/ (XLSX/XLSM/XLSB files)

Both pages are HTML5 File API-driven XLS/XLSX parsers (you can drag-drop your file and it will print out the data in the cells in a comma-separated list). You can also generate JSON objects (assuming the first row is a header row).

The test suite http://oss.sheetjs.com/ shows a version that uses XHR to get and parse files.

With these two steps we can check if it LL(1) or not. Both of them have to be satisfied.

1.If we have the production:A->a1|a2|a3|a4|.....|an. Then,First(a(i)) intersection First(a(j)) must be phi(empty set)[a(i)-a subscript i.]

2.For every non terminal 'A',if First(A) contains epsilon Then First(A) intersection Follow(A) must be phi(empty set).

inplace swapping (incase you already didn't know) can save a bit of space by not creating a temp variable.

arr[i] = arr[i] + arr[j];
arr[j] = arr[i] - arr[j];
arr[i] = arr[i] - arr[j];

Can't get exactly what you are asking but if you are using an aggregate SUM function which implies that you are grouping the table.

The query goes for MYSQL like this

Select IFNULL(SUM(COLUMN1),0) as total from mytable group by condition

Set the listview adapter to "simple_list_item_multiple_choice"

ArrayAdapter<String> adapter;

List<String> values; // put values in this

//Put in listview
adapter = new ArrayAdapter<UserProfile>(
this,
android.R.layout.simple_list_item_multiple_choice, 
values);
setListAdapter(adapter);    

Convert.ToString(value, CultureInfo.InvariantCulture);

Just an alternative. Searching google and parsing the results can also be done in a generic way using any HTML Parser such as Jsoup in Java. Following is the link to the mentioned example.

Update: Link no longer works. Please look for any other example. https://www.codeforeach.com/java/example-how-to-search-google-using-java

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

Before pushing, do a git pull with rebase option. This will get the changes that you made online (in your origin) and apply them locally, then add your local changes on top of it.

git pull --rebase

Now, you can push to remote

git push 

For more information take a look at Git rebase explained and Chapter 3.6 Git Branching - Rebasing.

If you don't want the $.ajax() function to return immediately, set the async option to false:

$(".my_link").click(
    function(){
    $.ajax({
        url: $(this).attr('href'),
        type: 'GET',
        async: false,
        cache: false,
        timeout: 30000,
        fail: function(){
            return true;
        },
        done: function(msg){ 
            if (parseFloat(msg)){
                return false;
            } else {
                return true;
            }
        }
    });
});

But, I would note that this would be counter to the point of AJAX. Also, you should be handling the response in the fail and done functions. Those functions will only be called when the response is received from the server.

Try this

Right Click on the Unit Test Class,

1. Select "Run As" -> Run Configuration
2. In the "Test" tab, make sure in the field "Test runner" select drop down "JUnit 4"
3. Click "Apply"

Now Run the test!

Sorting dictionaries by value using comprehensions. I think it's nice as 1 line and no need for functions or lambdas

a = {'b':'foo', 'c':'bar', 'e': 'baz'}
a = {f:a[f] for f in sorted(a, key=a.__getitem__)}

ubound(arr, 1) 

and

ubound(arr, 2) 

Deadlock occurs when a thread is waiting for other thread to finish and vice versa.

How to avoid?
- Avoid Nested Locks
- Avoid Unnecessary Locks
- Use thread join()

How do you detect it?
run this command in cmd:

jcmd $PID Thread.print

Easier procedure on latest versions:

• Copy jar to libs directory in the app (you can create the directory it if not there)
• Refresh project so libs show up in the structure (right click on project top level, refresh/synchronize)
• Expand libs and right click on the jar
• Select "Add as Library"

Done

Your path includes " at the beginning and at the end. Drop the quotes, and it'll be ok.

The \" at the beginning and end of what you see in VS Debugger is what tells us that the quotes are literally in the string.
