If you want most of your activities to have an action bar you would probably inherit your base theme from the default one (this is automatically generated by Android Studio per default):

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

And then add a special theme for your bar-less activity:

<style name="AppTheme.NoTitle" parent="AppTheme">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="actionBarTheme">@null</item>
    </style>

For me, setting actionBarTheme to @null was the solution.

Finally setup the activity in your manifest file:

<activity ... android:theme="@style/AppTheme.NoTitle" ... >

It's more convenient to use a session, this way you don't have to remember to set headers each time:

session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})

session.get('https://httpbin.org/headers')

By default, session also manages cookies for you. In case you want to disable that, see this question.

Since you are asking about .NET, you should change the parameter from Long to Integer. .NET's Integer is 32-bit. (Classic VB's integer was only 16-bit.)

Declare Sub Sleep Lib "kernel32.dll" (ByVal Milliseconds As Integer)

Really though, the managed method isn't difficult...

System.Threading.Thread.CurrentThread.Sleep(5000)

Be careful when you do this. In a forms application, you block the message pump and what not, making your program to appear to have hanged. Rarely is sleep a good idea.

Xcode did not see my iPad, iTunes also did not see my device. Rebooting Mac corrected the situation.

I have the same problem and waste so many time for it. So now I have my solution. My app setting is just support portrait only.However, some screens into my app need have landscape only.I fix it by have a variable isShouldRotate at AppDelegate. And the function at AppDelegate:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int {
    if isShouldRotate == true {
        return Int(UIInterfaceOrientationMask.Landscape.rawValue)
    }
    return Int(UIInterfaceOrientationMask.Portrait.rawValue)
}

And finally when a ViewControllerA need landscape state. Just do that: before push/present to ViewControllerA assign isShouldRotate to true. Don't forget when pop/dismiss that controller assign isShouldRotate to false at viewWillDisappear.

I'm assuming cross-domain iFrame since presumably the risk would be lower if you controlled it yourself.

• Clickjacking is a problem if your site is included as an iframe
• A compromised iFrame could display malicious content (imagine the iFrame displaying a login box instead of an ad)
• An included iframe can make certain JS calls like alert and prompt which could annoy your user
• An included iframe can redirect via location.href (yikes, imagine a 3p frame redirecting the customer from bankofamerica.com to bankofamerica.fake.com)
• Malware inside the 3p frame (java/flash/activeX) could infect your user

Yes: simply press and hold the Alt key, click and drag to select the lines whose columns you wish to edit, and begin typing.

You can also go to Settings > Preferences..., and in the Editing tab, turn on multi-editing, to enable selection of multiple separate regions or columns of text to edit at once.

It's much more intuitive, as you can see your edits live as you type.

After some trial and error I came to this solution:

function center(img) {
    var div = img.parentNode;
    var divW = parseInt(div.style.width);
    var divH = parseInt(div.style.height);
    var srcW = img.width;
    var srcH = img.height;
    var ratio = Math.min(divW/srcW, divH/srcH);
    var newW = img.width * ratio;
    var newH = img.height * ratio;
    img.style.width  = newW + "px";
    img.style.height = newH + "px";
    img.style.marginTop = (divH-newH)/2 + "px";
    img.style.marginLeft = (divW-newW)/2 + "px";
}

If it's a huuge array and it would take too much memory to serialize it to a string before writing, you can use streams:

var fs = require('fs');

var file = fs.createWriteStream('array.txt');
file.on('error', function(err) { /* error handling */ });
arr.forEach(function(v) { file.write(v.join(', ') + '\n'); });
file.end();

The following code works for me on owl carousel .

https://github.com/OwlFonk/OwlCarousel

$(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    navigation: true,
    navigationText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

For OwlCarousel2

https://owlcarousel2.github.io/OwlCarousel2/docs/api-options.html

 $(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    nav: true,
    navText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

you need to manually re-install sdk this help me: https://forum.ionicframework.com/t/you-have-not-accepted-the-license-agreements-of-the-following-sdk-component/69570/6

For debugging purposes, you can use the DLL file. You can run it using dotnet ConsoleApp2.dll. If you want to generate an EXE file, you have to generate a self-contained application.

To generate a self-contained application (EXE in Windows), you must specify the target runtime (which is specific to the operating system you target).

Pre-.NET Core 2.0 only: First, add the runtime identifier of the target runtimes in the .csproj file (list of supported RIDs):

<PropertyGroup>
    <RuntimeIdentifiers>win10-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
</PropertyGroup>

The above step is no longer required starting with .NET Core 2.0.

Then, set the desired runtime when you publish your application:

dotnet publish -c Release -r win10-x64
dotnet publish -c Release -r ubuntu.16.10-x64

By default Ansible will attempt to run on all hosts in parallel. See these Ansible docs for details. You can also use the serial parameter to limit the number of parallel hosts you want to be processed at any given time, so if you want to have a playbook run on just one host at a time you can specify serial:1, etc.

Ansible is designed so that each task will be run on all hosts before continuing on to the next task. So if you have 3 tasks it will ensure task 1 runs on all your hosts first, then task 2 is run, then task 3 is run. See this section of the Ansible docs for more details on this.

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

Trying to do more friendly solution of DecimalToString (https://stackoverflow.com/a/34486763/3852139):

private static decimal Trim(this decimal value)
{
    var s = value.ToString(CultureInfo.InvariantCulture);
    return s.Contains(CultureInfo.InvariantCulture.NumberFormat.NumberDecimalSeparator)
        ? Decimal.Parse(s.TrimEnd('0'), CultureInfo.InvariantCulture)
        : value;
}

private static decimal? Trim(this decimal? value)
{
    return value.HasValue ? (decimal?) value.Value.Trim() : null;
}

private static void Main(string[] args)
{
    Console.WriteLine("=>{0}", 1.0000m.Trim());
    Console.WriteLine("=>{0}", 1.000000023000m.Trim());
    Console.WriteLine("=>{0}", ((decimal?) 1.000000023000m).Trim());
    Console.WriteLine("=>{0}", ((decimal?) null).Trim());
}

Output:

=>1
=>1.000000023
=>1.000000023

Just start it with a slash? This means root. As long as you're testing on a web server (e.g. localhost) and not a file system (e.g. C:) then that should be all you need to do.

The git blame command is used to know who/which commit is responsible for the latest changes made to a file. The author/commit of each line can also been seen.

git blame filename (commits responsible for changes for all lines in code)

git blame filename -L 0,10 (commits responsible for changes from line "0" to line "10")

There are many other options for blame, but generally these could help.

you can just split it up and get the last element

var string="xxx_456";
var a=string.split("_");
alert(a[1]); #or a.pop

Use CSS stylesheet for solving this problem like the following code.

[divContainer_Id] img
{
    display:block;
    float:left;
    border:0;
}

Testing on Firefox 3.5 Final!

PS. your html should like this.

<div id="[divContainer_Id]">
    <img src="[image1_url]" alt="img1" />
    <img src="[image2_url]" alt="img2" />
    <img src="[image3_url]" alt="img3" />
    <img src="[image4_url]" alt="img4" />
    <img src="[image5_url]" alt="img5" />
    <img src="[image6_url]" alt="img6" />
</div>

Use an interval to check

You can setup an interval to keep checking if the user has scrolled then do something accordingly.

Borrowing from the great John Resig in his article.

Example:

    let didScroll = false;

    window.onscroll = () => didScroll = true;

    setInterval(() => {
        if ( didScroll ) {
            didScroll = false;
            console.log('Someone scrolled me!')
        }
    }, 250);

See live example

Without resorting gridspec entirely, the following might also be used to remove the gaps by setting wspace and hspace to zero:

import matplotlib.pyplot as plt

plt.clf()
f, axarr = plt.subplots(4, 4, gridspec_kw = {'wspace':0, 'hspace':0})

for i, ax in enumerate(f.axes):
    ax.grid('on', linestyle='--')
    ax.set_xticklabels([])
    ax.set_yticklabels([])

plt.show()
plt.close()

Resulting in:

Into psql terminal put:

\i <path to contrib files>

in ubuntu it usually is /usr/share/postgreslq/<your pg version>/contrib/<contrib file>.sql

If you're not worried about waking your phone up or bringing your app back from the dead, try:

// Param is optional, to run task on UI thread.     
Handler handler = new Handler(Looper.getMainLooper());
Runnable runnable = new Runnable() {
    @Override
    public void run() {
        // Do the task...
        handler.postDelayed(this, milliseconds) // Optional, to repeat the task.
    }
};
handler.postDelayed(runnable, milliseconds);

// Stop a repeating task like this.
handler.removeCallbacks(runnable);

I have the same issue. It seems that pip is the problem. Try

pip uninstall xlsxwriter
easy_install xlsxwriter

This can be used to find all the numeric values (even those formatted as text) in a sheet and convert them to single (CSng function).

For Each r In Sheets("Sheet1").UsedRange.SpecialCells(xlCellTypeConstants)
    If IsNumeric(r) Then
       r.Value = CSng(r.Value)
       r.NumberFormat = "0.00"
    End If
Next

Other type of format :

$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json';
$headers[] = 'Content-length: 0';

curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);

how random count in :

count, one := big.NewInt(0), big.NewInt(1)
count.SetString("100000000000000000000000", 10)

For graph API v2.1, you can get the like count using 1 call only and, therefore, no need to go through the paging.

For example, to get the number of likes of http://www.imdb.com

https://graph.facebook.com/414652589771/likes?summary=1

Graph API Explorer https://developers.facebook.com/tools/explorer/?method=GET&path=414652589771%2Flikes%3Fsummary%3D1&version=v2.1

It is somehow not documented (at least at the moment I submit this answer...). I found the answer in https://stackoverflow.com/a/18198957/1822624

I don't know if this is really any different, but rather than iterate over the query cursor, you could do something like this:

query.exec(function (err, results){
  if (err) res.writeHead(500, err.message)
  else if (!results.length) res.writeHead(404);
  else {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.write(JSON.stringify(results.map(function (msg){ return {msgId: msg.fileName}; })));
  }
  res.end();
});

just other option. goto PREFERENCES >> JAVA >> EDITOR >> TEMPLATES, Select @author and change the variable ${user}.

Mongodb v3.4

You need to do the following to create a secure database:

Make sure the user starting the process has permissions and that the directories exist (/data/db in this case).

1) Start MongoDB without access control.

mongod --port 27017 --dbpath /data/db

2) Connect to the instance.

mongo --port 27017

3) Create the user administrator (in the admin authentication database).

use admin
db.createUser(
  {
    user: "myUserAdmin",
    pwd: "abc123",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

4) Re-start the MongoDB instance with access control.

mongod --auth --port 27017 --dbpath /data/db

5) Connect and authenticate as the user administrator.

mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"

6) Create additional users as needed for your deployment (e.g. in the test authentication database).

use test
db.createUser(
  {
    user: "myTester",
    pwd: "xyz123",
    roles: [ { role: "readWrite", db: "test" },
             { role: "read", db: "reporting" } ]
  }
)

7) Connect and authenticate as myTester.

mongo --port 27017 -u "myTester" -p "xyz123" --authenticationDatabase "test"

I basically just explained the short version of the official docs here: https://docs.mongodb.com/master/tutorial/enable-authentication/

Modify the existing layout params and set layout params again

//Get the current layout params and update the Gravity
(iv.layoutParams as FrameLayout.LayoutParams).gravity = Gravity.START
//Set layout params again (this updates the view)
iv.layoutParams = layoutParams

Looks like no, though it was requested, and there’s a UDF for it.

Edit: Or there’s… this. Ugh.

I am using the code above but I have changed the delay effect by slideToggle.

It slides the dropdown on hover with animation.

$('.navbar .dropdown').hover(function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideToggle(400);
    }, function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideToggle(400)
    });

Make it simple and use R basic functions:

# To get the LEFT part:
> substr(a, 1, 4)
[1] "left"
> 
# To get the MIDDLE part:
> substr(a, 3, 7)
[1] "ftrig"
> 
# To get the RIGHT part:
> substr(a, 5, 10)
[1] "right"

The substr() function tells you where start and stop substr(x, start, stop)

I think that SYSLOG levels NOTICE and ALERT/EMERGENCY are largely superfluous for application-level logging - while CRITICAL/ALERT/EMERGENCY may be useful alert levels for an operator that may trigger different actions and notifications, to an application admin it's all the same as FATAL. And I just cannot sufficiently distinguish between being given a notice or some information. If the information is not noteworthy, it's not really information :)

I like Jay Cincotta's interpretation best - tracing your code's execution is something very useful in tech support, and putting trace statements into the code liberally should be encouraged - especially in combination with a dynamic filtering mechanism for logging the trace messages from specific application components. However DEBUG level to me indicates that we're still in the process of figuring out what's going on - I see DEBUG level output as a development-only option, not as something that should ever show up in a production log.

There is however a logging level that I like to see in my error logs when wearing the hat of a sysadmin as much as that of tech support, or even developer: OPER, for OPERATIONAL messages. This I use for logging a timestamp, the type of operation invoked, the arguments supplied, possibly a (unique) task identifier, and task completion. It's used when e.g. a standalone task is fired off, something that is a true invocation from within the larger long-running app. It's the sort of thing I want always logged, no matter whether anything goes wrong or not, so I consider the level of OPER to be higher than FATAL, so you can only turn it off by going to totally silent mode. And it's much more than mere INFO log data - a log level often abused for spamming logs with minor operational messages of no historical value whatsoever.

As the case dictates this information may be directed to a separate invocation log, or may be obtained by filtering it out of a large log recording more information. But it's always needed, as historical info, to know what was being done - without descending to the level of AUDIT, another totally separate log level that has nothing to do with malfunctions or system operation, doesn't really fit within the above levels (as it needs its own control switch, not a severity classification) and which definitely needs its own separate log file.

You need to create a comparator. I am not sure why each value needs its own map but here is what the comparator would look like:

class ListMapComparator implements Comparator {
    public int compare(Object obj1, Object obj2) {
         Map<String, String> test1 = (Map<String, String>) obj1;
         Map<String, String> test2 = (Map<String, String>) obj2;
         return test1.get("name").compareTo(test2.get("name"));
    }
}

You can see it working with your above example with this:

public class MapSort {
    public List<Map<String, String>> testMap() {
         List<Map<String, String>> list = new ArrayList<Map<String, String>>();
         Map<String, String> myMap1 = new HashMap<String, String>();
         myMap1.put("name", "Josh");
         Map<String, String> myMap2 = new HashMap<String, String>();
         myMap2.put("name", "Anna");

         Map<String, String> myMap3 = new HashMap<String, String>();
         myMap3.put("name", "Bernie");


         list.add(myMap1);
         list.add(myMap2);
         list.add(myMap3);

         return list;
    }

    public static void main(String[] args) {
         MapSort ms = new MapSort();
         List<Map<String, String>> testMap = ms.testMap();
         System.out.println("Before Sort: " + testMap);
         Collections.sort(testMap, new ListMapComparator());
         System.out.println("After Sort: " + testMap);
    }
}

You will have some type safe warnings because I did not worry about these. Hope that helps.

It would make for a handy function. Also, note I'm using STUFF instead of SUBSTRING.

create function str2uniq(@s varchar(50)) returns uniqueidentifier as begin
    -- just in case it came in with 0x prefix or dashes...
    set @s = replace(replace(@s,'0x',''),'-','')
    -- inject dashes in the right places
    set @s = stuff(stuff(stuff(stuff(@s,21,0,'-'),17,0,'-'),13,0,'-'),9,0,'-')
    return cast(@s as uniqueidentifier)
end

Adding /r/n between the Strings solved the problem for me. give it a try. On pasting dont include the '//' for excluding.

Eg: Option01\r\nOption02\r\nOption03

this will give output as
Option01
Option02
Option03

Consider the following servlet conf:

   <servlet>
        <servlet-name>NewServlet</servlet-name>
        <servlet-class>NewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>NewServlet</servlet-name>
        <url-pattern>/NewServlet/*</url-pattern>
    </servlet-mapping>

Now, when I hit the URL http://localhost:8084/JSPTemp1/NewServlet/jhi, it will invoke NewServlet as it is mapped with the pattern described above.

Here:

getRequestURI() =  /JSPTemp1/NewServlet/jhi
getPathInfo() = /jhi

We have those ones:

• getPathInfo()

  returns
  a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information

• getRequestURI()

  returns
  a String containing the part of the URL from the protocol name up to the query string

I also created a plugin that addresses this issue. My project - jQuery.floatThead has been around for over 4 years now and is very mature.

It requires no external styles and does not expect your table to be styled in any particular way. It supports Internet Explorer9+ and Firefox/Chrome.

Currently (2018-05) it has:

405 commits and 998 stars on GitHub

Many (not all) of the answers here are quick hacks that may have solved the problem one person was having, but will work not for every table.

Some of the other plugins are old and probably work great with Internet Explorer, but will break on Firefox and Chrome.

You can use

git commit -m "remove files" -a
git push

After you had delete files manually.

You can now use the npm package sequelize-auto-migrations to automatically generate a migrations file. https://www.npmjs.com/package/sequelize-auto-migrations

Using sequelize-cli, initialize your project with

sequelize init

Create your models and put them in your models folder.

Install sequelize-auto-migrations:

npm install sequelize-auto-migrations

Create an initial migration file with

node ./node_modules/sequelize-auto-migrations/bin/makemigration --name <initial_migration_name>

Run your migration:

node ./node_modules/sequelize-auto-migrations/bin/runmigration

You can also automatically generate your models from an existing database, but that is beyond the scope of the question.

Combine them. Literally combine them; attach them together without any punctuation.

$('.myclass[reference="12345"]')

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.

Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).

Here is what I did: I check the body y position , then make the body fixed and adjust the top to the negative of that position. On reverse, I make the body static and set the scroll to the value I recorded before.

var body_x_position = 0;

function disable_bk_scrl(){

    var elb = document.querySelector('body');

    body_x_position = elb.scrollTop;
    // get scroll position in px

    var body_x_position_m = body_x_position*(-1);
    console.log(body_x_position);

    document.body.style.position = "fixed";

    $('body').css({ top: body_x_position_m });

}

function enable_bk_scrl(){  

    document.body.style.position = "static";

    document.body.scrollTo(0, body_x_position);

    console.log(body_x_position);
}

Are you using JTextArea's append(String) method to add additional text?

JTextArea txtArea = new JTextArea("Hello, World\n", 20, 20);
txtArea.append("Goodbye Cruel World\n");

My favourite solution was the one by @EugenKonkov because it didn't imply the presence of other utilities (the coreutils package).

But it failed for the relative paths "." and "..", so here is a slightly improved version handling these special cases.

It still fails if the user doesn't have the permission to cd into the parent directory of the relative path, though.

#! /bin/sh

# Takes a path argument and returns it as an absolute path. 
# No-op if the path is already absolute.
function to-abs-path {
    local target="$1"

    if [ "$target" == "." ]; then
        echo "$(pwd)"
    elif [ "$target" == ".." ]; then
        echo "$(dirname "$(pwd)")"
    else
        echo "$(cd "$(dirname "$1")"; pwd)/$(basename "$1")"
    fi
}

You don't need quotes around the variable, so simply change this:

Get-ADComputer -Filter {name -like '$nameregex' -and Enabled -eq "true"}

into this:

Get-ADComputer -Filter {name -like $nameregex -and Enabled -eq "true"}

Note, however, that the scriptblock notation for filter statements is misleading, because the statement is actually a string, so it's better to write it as such:

Get-ADComputer -Filter "name -like '$nameregex' -and Enabled -eq 'true'"

Related. Also related.

And FTR: you're using wildcard matching here (operator -like), not regular expressions (operator -match).

I had an activity with theme <android:theme="@android:style/Theme.Dialog"> used for showing dialog in my appWidget and i had same problem

i solved this error by changing activity code like below:

    setTheme(R.style.Theme_AppCompat_Dialog); //this line i added
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dialog);
}

I also suggest using contourf(Z). For my problem, I wanted to visualize a 3D histogram in 2D, but the contours were too smooth to represent a top view of histogram bars.

So in my case, I prefer to use jucestain's answer. The default shading faceted of pcolor() is more suitable. However, pcolor() does not use the last row and column of the plotted matrix. For this, I used the padarray() function:

pcolor(padarray(Z,[1 1],0,'post'))

Sorry if that is not really related to the original post

Specifying a max-width or fixed width doesn't work for all situations, and the table should be fluid and auto-space its cells. That's what tables are for. Works on IE9 and other browsers.

Use this: http://jsfiddle.net/maruxa1j/

table {
    width: 100%;
}
.first {
    width: 50%;
}
.ellipsis {
    position: relative;
}
.ellipsis:before {
    content: ' ';
    visibility: hidden;
}
.ellipsis span {
    position: absolute;
    left: 0;
    right: 0;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

<table border="1">
    <thead>
        <tr>
            <th>Header 1</th>
            <th>Header 2</th>
            <th>Header 3</th>
            <th>Header 4</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td class="ellipsis first"><span>This Text Overflows and is too large for its cell.</span></td>

as a side note: the calls to Encrypt() and Decrypt() have a bool parameter that switches between OAEP and PKCS#1.5 padding ... you might want to choose OAEP if it's available in your situation

There are a couple of variants of a rename command, in your case, it may be as simple as

rename ABC XYZ *.dat

You may have a version which takes a Perl regex;

rename 's/ABC/XYZ/' *.dat

Can be done with preg_replace:

function str_replace_first($from, $to, $content)
{
    $from = '/'.preg_quote($from, '/').'/';

    return preg_replace($from, $to, $content, 1);
}

echo str_replace_first('abc', '123', 'abcdef abcdef abcdef'); 
// outputs '123def abcdef abcdef'

The magic is in the optional fourth parameter [Limit]. From the documentation:

[Limit] - The maximum possible replacements for each pattern in each subject string. Defaults to -1 (no limit).

Though, see zombat's answer for a more efficient method (roughly, 3-4x faster).

Use $ne instead of $not

http://docs.mongodb.org/manual/reference/operator/ne/#op._S_ne

db.collections.find({"name": {$ne: ""}});

Its a FF47 issue https://github.com/SeleniumHQ/selenium/issues/2110

Please downgrade to FF 46 or below (or try out FF48 developer https://developer.mozilla.org/en-US/Firefox/Releases/48)

Instructions on how to downgrade: https://www.liberiangeek.net/2012/04/how-to-install-previous-versions-of-firefox-in-ubuntu-12-04-precise-pangolin/ Or if you are on Mac, as suggested by someone else in this thread use brew.

Remove the function and check the output of:

var_dump(function_exists('parseDate'));

In which case, change the name of the function.

If you get false, you're including the file with that function twice, replace :

include

by

include_once

And replace :

require

by

require_once

EDIT : I'm just a little too late, post before beat me to it !

If you have readonly attribute, blur by itself would not work. Contraption below should do the job.

$('#myInputID').removeAttr('readonly').trigger('blur').attr('readonly','readonly');

find and replace:

utf8mb4_unicode_520_ci

with

utf8_general_ci

Ask your DBA about auditing. He can start an audit with a simple command like :

AUDIT INSERT ON user.table

Then you can query the table USER_AUDIT_OBJECT to determine if there has been an insert on your table since the last export.

google for Oracle auditing for more info...

Note: The following only works for the next line of code, and only due to a coincidence.

With Lodash,

require('lodash');
_.isArray([]); // true

No var _ = require('lodash') since Lodash mysteriously sets this value globally when required.

You need to include inttypes.h if you want all those nifty new format specifiers for the intN_t types and their brethren, and that is the correct (ie, portable) way to do it, provided your compiler complies with C99. You shouldn't use the standard ones like %d or %u in case the sizes are different to what you think.

It includes stdint.h and extends it with quite a few other things, such as the macros that can be used for the printf/scanf family of calls. This is covered in section 7.8 of the ISO C99 standard.

For example, the following program:

#include <stdio.h>
#include <inttypes.h>
int main (void) {
    uint32_t a=1234;
    uint16_t b=5678;
    printf("%" PRIu32 "\n",a);
    printf("%" PRIu16 "\n",b);
    return 0;
}

outputs:

1234
5678

It's the identifier for your current session in PHP. If you delete it, you won't be able to access/make use of session variables. I'd suggest you keep it.

_{Additional details to the previous answer:}

While React's setState is asynchronous (both classes and hooks), and it's tempting to use that fact to explain the observed behavior, it is not the reason why it happens.

TLDR: The reason is a closure scope around an immutable const value.

Solutions:

• read the value in render function (not inside nested functions):

    useEffect(() => { setMovies(result) }, [])
    console.log(movies)
  

• add the variable into dependencies (and use the react-hooks/exhaustive-deps eslint rule):

    useEffect(() => { setMovies(result) }, [])
    useEffect(() => { console.log(movies) }, [movies])
  

• use a mutable reference (when the above is not possible):

    const moviesRef = useRef(initialValue)
    useEffect(() => {
      moviesRef.current = result
      console.log(moviesRef.current)
    }, [])
  

Explanation why it happens:

If async was the only reason, it would be possible to await setState().

However, both props and state are assumed to be unchanging during 1 render.

Treat this.state as if it were immutable.

With hooks, this assumption is enhanced by using constant values with the const keyword:

const [state, setState] = useState('initial')

The value might be different between 2 renders, but remains a constant inside the render itself and inside any closures (functions that live longer even after render is finished, e.g. useEffect, event handlers, inside any Promise or setTimeout).

Consider following fake, but synchronous, React-like implementation:

// sync implementation:

let internalState
let renderAgain

const setState = (updateFn) => {
  internalState = updateFn(internalState)
  renderAgain()
}

const useState = (defaultState) => {
  if (!internalState) {
    internalState = defaultState
  }
  return [internalState, setState]
}

const render = (component, node) => {
  const {html, handleClick} = component()
  node.innerHTML = html
  renderAgain = () => render(component, node)
  return handleClick
}

// test:

const MyComponent = () => {
  const [x, setX] = useState(1)
  console.log('in render:', x) // ?
  
  const handleClick = () => {
    setX(current => current + 1)
    console.log('in handler/effect/Promise/setTimeout:', x) // ? NOT updated
  }
  
  return {
    html: `<button>${x}</button>`,
    handleClick
  }
}

const triggerClick = render(MyComponent, document.getElementById('root'))
triggerClick()
triggerClick()
triggerClick()

<div id="root"></div>

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

Boolean types are defined in documentation:
http://docs.python.org/library/stdtypes.html#boolean-values

Quoted from doc:

Boolean values are the two constant objects False and True. They are used to represent truth values (although other values can also be considered false or true). In numeric contexts (for example when used as the argument to an arithmetic operator), they behave like the integers 0 and 1, respectively. The built-in function bool() can be used to cast any value to a Boolean, if the value can be interpreted as a truth value (see section Truth Value Testing above).

They are written as False and True, respectively.

So in java code remove braces, change true to True and you will be ok :)

Working with VS 2013. Try the following

Tools -> Options -> Debugging -> Output Window -> Module Load Messages -> Off

It will disable the display of modules loaded.

For me, it was because I had temporarily excluded the file from the project. I merely included it in back in the project and then it worked.

To add:

$arr["key"] = "value";

Then simply return $arr

Can't return directly like this way return $arr["key"] = "value";

The error tells you EXACTLY what the problem is (and running in the debugger or reading the stack trace will tell you exactly where the problem is):

C# Collection was modified; enumeration operation may not execute.

Your problem is the loop

foreach (KeyValuePair<int, int> kvp in rankings) {
    //
}

wherein you modify the collection rankings. In particular, the offensive line is

rankings[kvp.Key] = rankings[kvp.Key] + 4;

Before you enter the loop, add the following line:

var listOfRankingsToModify = new List<int>();

Replace the offending line with

listOfRankingsToModify.Add(kvp.Key);

and after you exit the loop

foreach(var key in listOfRankingsToModify) {
    rankings[key] = rankings[key] + 4;
}

That is, record what changes you need to make, and make them without iterating over the collection that you need to modify.

Answer

You need to create a header with a proper formatted User agent String, it server to communicate client-server.

You can check your own user agent Here.

Example

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0
Mozilla/5.0 (Macintosh; Intel Mac OS X x.y; rv:42.0) Gecko/20100101 Firefox/42.0

Third party Package user_agent 0.1.9

I found this module very simple to use, in one line of code it randomly generates a User agent string.

from user_agent import generate_user_agent, generate_navigator
from pprint import pprint

print(generate_user_agent())
# 'Mozilla/5.0 (compatible; MSIE 8.0; Windows NT 6.3; Win64; x64)'

print(generate_user_agent(os=('mac', 'linux')))
# 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:36.0) Gecko/20100101 Firefox/36.0'

pprint(generate_navigator())

# {'app_code_name': 'Mozilla',
#  'app_name': 'Netscape',
#  'appversion': '5.0',
#  'name': 'firefox',
#  'os': 'linux',
#  'oscpu': 'Linux i686 on x86_64',
#  'platform': 'Linux i686 on x86_64',
#  'user_agent': 'Mozilla/5.0 (X11; Ubuntu; Linux i686 on x86_64; rv:41.0) Gecko/20100101 Firefox/41.0',
#  'version': '41.0'}

pprint(generate_navigator_js())

# {'appCodeName': 'Mozilla',
#  'appName': 'Netscape',
#  'appVersion': '38.0',
#  'platform': 'MacIntel',
#  'userAgent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:38.0) Gecko/20100101 Firefox/38.0'}

Java solution (In-app review API by Google in 2020):

You can now use In app review API provided by Google out of the box.

First, in your build.gradle(app) file, add following dependencies (full setup can be found here)

dependencies {
    // This dependency is downloaded from the Google’s Maven repository.
    // So, make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:core:1.8.0'
}

Add this method to your Activity:

void askRatings() {
    ReviewManager manager = ReviewManagerFactory.create(this);
    Task<ReviewInfo> request = manager.requestReviewFlow();
    request.addOnCompleteListener(task -> {
        if (task.isSuccessful()) {
            // We can get the ReviewInfo object
            ReviewInfo reviewInfo = task.getResult();
            Task<Void> flow = manager.launchReviewFlow(this, reviewInfo);
            flow.addOnCompleteListener(task2 -> {
                // The flow has finished. The API does not indicate whether the user
                // reviewed or not, or even whether the review dialog was shown. Thus, no
                // matter the result, we continue our app flow.
            });
        } else {
            // There was some problem, continue regardless of the result.
        }
    });
}

And then you can simply call it using

askRatings();

Great question, great answers. Here's a quick way to echo the results if anyone is reading this page and missing that part:

$counter = mysql_query("SELECT COUNT(*) AS id FROM table");
$num = mysql_fetch_array($counter);
$count = $num["id"];
echo("$count");

S LICE = Gives part of array & NO splitting original array

SP LICE = Gives part of array & SPlitting original array

I personally found this easier to remember, as these 2 terms always confused me as beginner to web development.

1. Find Debug/Release in CONFIG

Get the current (debug | release).

specified_configs=$$find(CONFIG, "\b(debug|release)\b")
build_subdir=$$last(specified_configs)

(May be multiple, so keep only last specified in the build):

2. Set DESTDIR

Use it has the build subdir name

DESTDIR = $$PWD/build/$$build_subdir

guppy3 is quite simple to use. At some point in your code, you have to write the following:

from guppy import hpy
h = hpy()
print(h.heap())

This gives you some output like this:

Partition of a set of 132527 objects. Total size = 8301532 bytes.
Index  Count   %     Size   % Cumulative  % Kind (class / dict of class)
0  35144  27  2140412  26   2140412  26 str
1  38397  29  1309020  16   3449432  42 tuple
2    530   0   739856   9   4189288  50 dict (no owner)

You can also find out from where objects are referenced and get statistics about that, but somehow the docs on that are a bit sparse.

There is a graphical browser as well, written in Tk.

For Python 2.x, use Heapy.

I had this problem also. I set the correct settings and have enabled less secure apps but it still did not work. Finally, I enabled this https://accounts.google.com/UnlockCaptcha, and it worked for me. I hope this helps someone.

From this answer:

[HttpPost]
public void Confirmation(HttpRequestMessage request)
{
    var content = request.Content;
    string jsonContent = content.ReadAsStringAsync().Result;
}

Note: As seen in the comments, this code could cause a deadlock and should not be used. See this blog post for more detail.

echo $a | grep -bo cat | sed 's/:.*$//'

You can try with

var result = DateTime.Now.ToString("yyyy-MM-d--HH-mm-ss");

It depends upon the context. Some possible contexts in HTML:

• document body
• inside common attributes
• inside script tags
• inside style tags
• several more!

See OWASP's Cross Site Scripting Prevention Cheat Sheet, especially the "Why Can't I Just HTML Entity Encode Untrusted Data?" and "XSS Prevention Rules" sections. However, it's best to read the whole document.

You can't remove keyword case. But your example can be written shorter like this:

switch ((Answer - 1) / 4)                                      
{
   case 0:
      cout << "You need more cars.";
      break;                                        
   case 1:
      cout << "Now you need a house.";
      break;                                        
   default:
      cout << "What are you? A peace-loving hippie freak?";
}

There are a few things interacting here:

1. docker run your_image arg1 arg2 will replace the value of CMD with arg1 arg2. That's a full replacement of the CMD, not appending more values to it. This is why you often see docker run some_image /bin/bash to run a bash shell in the container.

2. When you have both an ENTRYPOINT and a CMD value defined, docker starts the container by concatenating the two and running that concatenated command. So if you define your entrypoint to be file.sh, you can now run the container with additional args that will be passed as args to file.sh.

3. Entrypoints and Commands in docker have two syntaxes, a string syntax that will launch a shell, and a json syntax that will perform an exec. The shell is useful to handle things like IO redirection, chaining multiple commands together (with things like &&), variable substitution, etc. However, that shell gets in the way with signal handling (if you've ever seen a 10 second delay to stop a container, this is often the cause) and with concatenating an entrypoint and command together. If you define your entrypoint as a string, it would run /bin/sh -c "file.sh", which alone is fine. But if you have a command defined as a string too, you'll see something like /bin/sh -c "file.sh" /bin/sh -c "arg1 arg2" as the command being launched inside your container, not so good. See the table here for more on how these two options interact

4. The shell -c option only takes a single argument. Everything after that would get passed as $1, $2, etc, to that single argument, but not into an embedded shell script unless you explicitly passed the args. I.e. /bin/sh -c "file.sh $1 $2" "arg1" "arg2" would work, but /bin/sh -c "file.sh" "arg1" "arg2" would not since file.sh would be called with no args.

Putting that all together, the common design is:

FROM ubuntu:14.04
COPY ./file.sh /
RUN chmod 755 /file.sh
# Note the json syntax on this next line is strict, double quotes, and any syntax
# error will result in a shell being used to run the line.
ENTRYPOINT ["file.sh"]

And you then run that with:

docker run your_image arg1 arg2

There's a fair bit more detail on this at:

• https://docs.docker.com/engine/reference/run/#cmd-default-command-or-options
• https://docs.docker.com/engine/reference/builder/#exec-form-entrypoint-example

You can do this:

DB::transaction(function() {
      //
});

Everything inside the Closure executes within a transaction. If an exception occurs it will rollback automatically.

import requests
r = requests.get("https://stackoverflow.com") 
data = r.content  # Content of response

print r.status_code  # Status code of response
print data

it's possible with v2 = Convert.ToInt32(v1);

Another possibility would be to have a little NSNumber subclass singleton.

The problem with other answers is they either use a global, which can be overwritten when several functions are in a call chain, or echo which means your function cannot output diagnostic info (you will forget your function does this and the "result", i.e. return value, will contain more info than your caller expects, leading to weird bug), or eval which is way too heavy and hacky.

The proper way to do this is to put the top level stuff in a function and use a local with bash's dynamic scoping rule. Example:

func1() 
{
    ret_val=hi
}

func2()
{
    ret_val=bye
}

func3()
{
    local ret_val=nothing
    echo $ret_val
    func1
    echo $ret_val
    func2
    echo $ret_val
}

func3

This outputs

nothing
hi
bye

Dynamic scoping means that ret_val points to a different object depending on the caller! This is different from lexical scoping, which is what most programming languages use. This is actually a documented feature, just easy to miss, and not very well explained, here is the documentation for it (emphasis is mine):

Variables local to the function may be declared with the local builtin. These variables are visible only to the function and the commands it invokes.

For someone with a C/C++/Python/Java/C#/javascript background, this is probably the biggest hurdle: functions in bash are not functions, they are commands, and behave as such: they can output to stdout/stderr, they can pipe in/out, they can return an exit code. Basically there is no difference between defining a command in a script and creating an executable that can be called from the command line.

So instead of writing your script like this:

top-level code 
bunch of functions
more top-level code

write it like this:

# define your main, containing all top-level code
main() 
bunch of functions
# call main
main  

where main() declares ret_val as local and all other functions return values via ret_val.

See also the following Unix & Linux question: Scope of Local Variables in Shell Functions.

Another, perhaps even better solution depending on situation, is the one posted by ya.teck which uses local -n.

I suggest to use an extension for code neatness. Note that extending an internal object prototype could potentially mess with libraries that depend on them.

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

And use it like:

var stringObject= 'this is a verrrryyyyyyyyyyyyyyyyyyyyyyyyyyyyylllooooooooooooonggggggggggggsssssssssssssttttttttttrrrrrrrrriiiiiiiiiiinnnnnnnnnnnnggggggggg';
stringObject.trimEllip(25)

(WINDOWS - AWS solution)
Solved for windows by putting tripple quotes around files and paths.
Benefits:
1) Prevents excludes that quietly were getting ignored.
2) Files/folders with spaces in them, will no longer kick errors.

    aws_command = 'aws s3 sync """D:/""" """s3://mybucket/my folder/"  --exclude """*RECYCLE.BIN/*""" --exclude """*.cab""" --exclude """System Volume Information/*""" '

    r = subprocess.run(f"powershell.exe {aws_command}", shell=True, capture_output=True, text=True)

Perhaps:

Sub dateCNV()
    Dim N As Long, r As Range, s As String
    N = Cells(Rows.Count, "A").End(xlUp).Row
    For i = 1 To N
        Set r = Cells(i, "A")
        s = r.Text
        r.Clear
        r.Value = DateSerial(Left(s, 4), Mid(s, 6, 2), Right(s, 2))
    Next i
End Sub

This assumes that column A contains text values like 2013-12-25 with no header cell.

Further to the answer from Diodeus above, you need the font-family: FontAwesome rule (assuming you have the @font-face rule for FontAwesome declared already in your CSS). Then it is a matter of knowing which CSS content value corresponds to which icon.

I have listed them all here: http://astronautweb.co/snippet/font-awesome/

window.open('https://support.wwf.org.uk', '_blank');

The second parameter is what makes it open in a new window. Don't forget to read Jakob Nielsen's informative article :)

text-overflow:ellipsis; only works when the following are true:

• The element's width must be constrained in px (pixels). Width in % (percentage) won't work.
• The element must have overflow:hidden and white-space:nowrap set.

The reason you're having problems here is because the width of your a element isn't constrained. You do have a width setting, but because the element is set to display:inline (i.e. the default) it is ignoring it, and nothing else is constraining its width either.

You can fix this by doing one of the following:

• Set the element to display:inline-block or display:block (probably the former, but depends on your layout needs).
• Set one of its container elements to display:block and give that element a fixed width or max-width.
• Set the element to float:left or float:right (probably the former, but again, either should have the same effect as far as the ellipsis is concerned).

I'd suggest display:inline-block, since this will have the minimum collateral impact on your layout; it works very much like the display:inline that it's using currently as far as the layout is concerned, but feel free to experiment with the other points as well; I've tried to give as much info as possible to help you understand how these things interact together; a large part of understanding CSS is about understanding how various styles work together.

Here's a snippet with your code, with a display:inline-block added, to show how close you were.

.app a {_x000D_
  height: 18px;_x000D_
  width: 140px;_x000D_
  padding: 0;_x000D_

  position: relative;_x000D_
  display: inline-block;_x000D_
  margin: 0 5px 0 5px;_x000D_

  text-overflow: ellipsis;_x000D_

PARTITION BY segregate sets, this enables you to be able to work(ROW_NUMBER(),COUNT(),SUM(),etc) on related set independently.

In your query, the related set comprised of rows with similar cdt.country_code, cdt.account, cdt.currency. When you partition on those columns and you apply ROW_NUMBER on them. Those other columns on those combination/set will receive sequential number from ROW_NUMBER

But that query is funny, if your partition by some unique data and you put a row_number on it, it will just produce same number. It's like you do an ORDER BY on a partition that is guaranteed to be unique. Example, think of GUID as unique combination of cdt.country_code, cdt.account, cdt.currency

newid() produces GUID, so what shall you expect by this expression?

select
   hi,ho,
   row_number() over(partition by newid() order by hi,ho)
from tbl;

...Right, all the partitioned(none was partitioned, every row is partitioned in their own row) rows' row_numbers are all set to 1

Basically, you should partition on non-unique columns. ORDER BY on OVER needed the PARTITION BY to have a non-unique combination, otherwise all row_numbers will become 1

An example, this is your data:

create table tbl(hi varchar, ho varchar);

insert into tbl values
('A','X'),
('A','Y'),
('A','Z'),
('B','W'),
('B','W'),
('C','L'),
('C','L');

Then this is analogous to your query:

select
   hi,ho,
   row_number() over(partition by hi,ho order by hi,ho)
from tbl;

What will be the output of that?

HI  HO  COLUMN_2
A   X   1
A   Y   1
A   Z   1
B   W   1
B   W   2
C   L   1
C   L   2

You see thee combination of HI HO? The first three rows has unique combination, hence they are set to 1, the B rows has same W, hence different ROW_NUMBERS, likewise with HI C rows.

Now, why is the ORDER BY needed there? If the previous developer merely want to put a row_number on similar data (e.g. HI B, all data are B-W, B-W), he can just do this:

select
   hi,ho,
   row_number() over(partition by hi,ho)
from tbl;

But alas, Oracle(and Sql Server too) doesn't allow partition with no ORDER BY; whereas in Postgresql, ORDER BY on PARTITION is optional: http://www.sqlfiddle.com/#!1/27821/1

select
   hi,ho,
   row_number() over(partition by hi,ho)
from tbl;

Your ORDER BY on your partition look a bit redundant, not because of the previous developer's fault, some database just don't allow PARTITION with no ORDER BY, he might not able find a good candidate column to sort on. If both PARTITION BY columns and ORDER BY columns are the same just remove the ORDER BY, but since some database don't allow it, you can just do this:

SELECT cdt.*,
        ROW_NUMBER ()
        OVER (PARTITION BY cdt.country_code, cdt.account, cdt.currency
              ORDER BY newid())
           seq_no
   FROM CUSTOMER_DETAILS cdt

You cannot find a good column to use for sorting similar data? You might as well sort on random, the partitioned data have the same values anyway. You can use GUID for example(you use newid() for SQL Server). So that has the same output made by previous developer, it's unfortunate that some database doesn't allow PARTITION with no ORDER BY

Though really, it eludes me and I cannot find a good reason to put a number on the same combinations (B-W, B-W in example above). It's giving the impression of database having redundant data. Somehow reminded me of this: How to get one unique record from the same list of records from table? No Unique constraint in the table

It really looks arcane seeing a PARTITION BY with same combination of columns with ORDER BY, can not easily infer the code's intent.

Live test: http://www.sqlfiddle.com/#!3/27821/6

But as dbaseman have noticed also, it's useless to partition and order on same columns.

You have a set of data like this:

create table tbl(hi varchar, ho varchar);

insert into tbl values
('A','X'),
('A','X'),
('A','X'),
('B','Y'),
('B','Y'),
('C','Z'),
('C','Z');

Then you PARTITION BY hi,ho; and then you ORDER BY hi,ho. There's no sense numbering similar data :-) http://www.sqlfiddle.com/#!3/29ab8/3

select
   hi,ho,
   row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;

Output:

HI  HO  ROW_QUERY_A
A   X   1
A   X   2
A   X   3
B   Y   1
B   Y   2
C   Z   1
C   Z   2

See? Why need to put row numbers on same combination? What you will analyze on triple A,X, on double B,Y, on double C,Z? :-)

You just need to use PARTITION on non-unique column, then you sort on non-unique column(s)'s unique-ing column. Example will make it more clear:

create table tbl(hi varchar, ho varchar);

insert into tbl values
('A','D'),
('A','E'),
('A','F'),
('B','F'),
('B','E'),
('C','E'),
('C','D');

select
   hi,ho,
   row_number() over(partition by hi order by ho) as nr
from tbl;

PARTITION BY hi operates on non unique column, then on each partitioned column, you order on its unique column(ho), ORDER BY ho

Output:

HI  HO  NR
A   D   1
A   E   2
A   F   3
B   E   1
B   F   2
C   D   1
C   E   2

That data set makes more sense

Live test: http://www.sqlfiddle.com/#!3/d0b44/1

And this is similar to your query with same columns on both PARTITION BY and ORDER BY:

select
   hi,ho,
   row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;

And this is the ouput:

HI  HO  NR
A   D   1
A   E   1
A   F   1
B   E   1
B   F   1
C   D   1
C   E   1

See? no sense?

Live test: http://www.sqlfiddle.com/#!3/d0b44/3

Finally this might be the right query:

SELECT cdt.*,
     ROW_NUMBER ()
     OVER (PARTITION BY cdt.country_code, cdt.account -- removed: cdt.currency
           ORDER BY 
               -- removed: cdt.country_code, cdt.account, 
               cdt.currency) -- keep
        seq_no
FROM CUSTOMER_DETAILS cdt

After making the shortcut as you have, set the following in Properties:

Target: %comspec% /k "data\run.bat"

• Drop the /k if you don't want the prompt to stay open after you've run it.

Start In: %cd%\data

You're using the wrong method calls. A viewport is the "window" that's open on the document: how much of it you can see and where.

Using $(window).height() will not give you the viewport size it will give you the size of the entire window, which is usually the size of the entire document though the document could be even larger.

To get the size of the actual viewport use window.innerHeight and window.innerWidth.

https://gist.github.com/bohman/1351439

Do not use the jQuery methods, e.g. $(window).innerHeight(), as these give the wrong numbers. They give you the window's height, not innerHeight.

import sys

try:
  print("stuff")
except:
  sys.exit(1) # exiing with a non zero value is better for returning from an error

Column(children: <Widget>[
   Container(margin: EdgeInsets.only(top:12, child: yourWidget)),
   Container(margin: EdgeInsets.only(top:12, child: yourWidget))
]);

There are 2 things you must accomplish to serve the assets in production:

1. Precompile the assets.
2. Serve the assets on the server to browser.

1) In order to precompile the assets, you have several choices.

• You can run rake assets:precompile on your local machine, commit it to source code control (git), then run the deployment program, for example capistrano. This is not a good way to commit precompiled assets to SCM.

• You can write a rake task that run RAILS_ENV=production rake assets:precompile on the target servers each time you deploy your Rails app to production, before you restart the server.

Code in a task for capistrano will look similar to this:

on roles(:app) do
  if DEPLOY_ENV == 'production'
    execute("cd #{DEPLOY_TO_DIR}/current && RAILS_ENV=production rvm #{ruby_string} do rake assets:precompile")
  end
end

2) Now, you have the assets on production servers, you need to serve them to browser.

Again, you have several choices.

• Turn on Rails static file serving in config/environments/production.rb

  config.serve_static_assets = true # old
  
  or
  
  config.serve_static_files = true # new
  

  Using Rails to serve static files will kill your Rails app performance.

• Configure nginx (or Apache) to serve static files.

  For example, my nginx that was configured to work with Puma looks like this:

  location ~ ^/(assets|images|fonts)/(.*)$ {
      alias /var/www/foster_care/current/public/$1/$2;
      gzip on;
      expires max;
      add_header Cache-Control public;
  }
  

If you want to apply styles only to an element which is its parents' first child, is it better to use :first-child pseudo-class

.social:first-child{
    border-bottom: dotted 1px #6d6d6d;
    padding-top: 0;
}
.social{
    border: 0;
    width: 330px;
    height: 75px;
    float: right;
    text-align: left;
    padding: 10px 0;
}

Then, the rule .social has both common styles and the last element's styles.

And .social:first-child overrides them with first element's styles.

You could also use :last-child selector, but :first-childis more supported by old browsers: see https://developer.mozilla.org/en-US/docs/CSS/:first-child#Browser_compatibility and https://developer.mozilla.org/es/docs/CSS/:last-child#Browser_compatibility.

You can define a Headers object with a dictionary of HTTP key/value pairs, and then pass it in as an argument to http.get() and http.post() like this:

const headerDict = {
  'Content-Type': 'application/json',
  'Accept': 'application/json',
  'Access-Control-Allow-Headers': 'Content-Type',
}

const requestOptions = {                                                                                                                                                                                 
  headers: new Headers(headerDict), 
};

return this.http.get(this.heroesUrl, requestOptions)

Or, if it's a POST request:

const data = JSON.stringify(heroData);
return this.http.post(this.heroesUrl, data, requestOptions);

Since Angular 7 and up you have to use HttpHeaders class instead of Headers:

const requestOptions = {                                                                                                                                                                                 
  headers: new HttpHeaders(headerDict), 
};

Here's another way:

>>> L = range (11)
>>> map(lambda x: x if x%2 else None, L)
[None, 1, None, 3, None, 5, None, 7, None, 9, None]

I would just use table and not the form. Its done by using margin.

table {
  margin: 0 auto;
}

also try using something like

table td {
    padding-bottom: 5px;
}

instead of <br />

and also your input should end with /> e.g:

<input type="password" name="cpwd" />

By the way guys, (int)Decimal.MaxValue will overflow. You can't get the "int" part of a decimal because the decimal is too friggen big to put in the int box. Just checked... its even too big for a long (Int64).

If you want the bit of a Decimal value to the LEFT of the dot, you need to do this:

Math.Truncate(number)

and return the value as... A DECIMAL or a DOUBLE.

edit: Truncate is definitely the correct function!

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

This: "\0" is a string, not a character. A character uses single quotes, like '\0'.

The procedure name should be in caps while creating procedure in database. You may use small letters for your procedure name while calling from Java class like:

String getDBUSERByUserIdSql = "{call getDBUSERByUserId(?,?,?,?)}";

In database the name of procedure should be:

GETDBUSERBYUSERID    -- (all letters in caps only)

This serves as one of the solutions for this problem.

SSH itself provides a means of communication, it does not know anything about directories. Since you can specify which remote command to execute (this is - by default - your shell), I'd start there.

I'm not sure why this work but using Pycharm build from file_in_same_dir import class_name

The IDE complained about it but it seems it still worked. I'm using Python 3.7

1. Delete the app from the device.
2. Edit the file (YourAppName -> android -> app -> build.gradle) enter the line below on the defaultConfig field

multiDexEnabled true

defaultConfig {
    multiDexEnabled true //this is the line you need to enter
    applicationId "xxxxxx"
    minSdkVersion xxxxx
    targetSdkVersion xxxxx
    versionCode xx
    versionName "xx"
}

3. rebuild the app

I know this is already answered, but none of the current answers make any mention of namespacing and how it affects constants and defines.

As of PHP 5.3, consts and defines are similar in most respects. There are still, however, some important differences:

• Consts cannot be defined from an expression. const FOO = 4 * 3; doesn't work, but define('CONST', 4 * 3); does.
• The name passed to define must include the namespace to be defined within that namespace.

The code below should illustrate the differences.

namespace foo 
{
    const BAR = 1;
    define('BAZ', 2);
    define(__NAMESPACE__ . '\\BAZ', 3);
}

namespace {
    var_dump(get_defined_constants(true));
}

The content of the user sub-array will be ['foo\\BAR' => 1, 'BAZ' => 2, 'foo\\BAZ' => 3].

=== UPDATE ===

The upcoming PHP 5.6 will allow a bit more flexibility with const. You will now be able to define consts in terms of expressions, provided that those expressions are made up of other consts or of literals. This means the following should be valid as of 5.6:

const FOOBAR = 'foo ' . 'bar';
const FORTY_TWO = 6 * 9; // For future editors: THIS IS DELIBERATE! Read the answer comments below for more details
const ULTIMATE_ANSWER = 'The ultimate answer to life, the universe and everything is ' . FORTY_TWO;

You still won't be able to define consts in terms of variables or function returns though, so

const RND = mt_rand();
const CONSTVAR = $var;

will still be out.

If You have 404 or errors while sudo apt-get install php-curl just try

sudo apt-get update

and again try

sudo apt-get install php-curl

But notice what version was installed (i use php7.3 and php7.4-curl was installed - so it will not work)

try then

sudo apt-get install php7.3-curl

At the end You may want to restart services like: apache2 or php-fpm:

sudo apache2 restart
sudo service php7.3-fpm restart

this worked for me.

Check if curl is on the installed modules list for current php:

php -m

Functionality-wise they are identical but I use them in the following scenarios to make code readable:

Use die() when there is an error and have to stop the execution.

e.g. die( 'Oops! Something went wrong' );

Use exit() when there is not an error and have to stop the execution.

e.g. exit( 'Request has been processed successfully!' );

If you want to browse code changes (see what actually has been changed with the given word in the whole history) go for patch mode - I found a very useful combination of doing:

git log -p
# Hit '/' for search mode.
# Type in the word you are searching.
# If the first search is not relevant, hit 'n' for next (like in Vim ;) )

I created a custom view that is at 100%. Use the dropdowns then click to view page layout to go back to a smaller view.

You can use async import():

import fs = require('fs');

and then:

fs.readdir('./someDir', (err, files) => {
 files.forEach(file => {
  const module = import('./' + file).then(m =>
    m.callSomeMethod();
  );
  // or const module = await import('file')
  });
});

For data import scripts, to replace "IF NOT EXISTS", in a way, there's a slightly awkward formulation that nevertheless works:

DO
$do$
BEGIN
PERFORM id
FROM whatever_table;

IF NOT FOUND THEN
-- INSERT stuff
END IF;
END
$do$;

you can use in_array function of php

$array=array('abc', 'def', 'hij', 'klm', 'nop');

if (in_array($val,$array))
{
  echo 'Value found';
}

You just use this: if not exist "C:\VTS\" mkdir C:\VTS it wll create a directory only if the folder does not exist.

Note that this existence test will return true only if VTS exists and is a directory. If it is not there, or is there as a file, the mkdir command will run, and should cause an error. You might want to check for whether VTS exists as a file as well.

For all those facing a similar issue, I came across this same issue when i was trying to run a particular code snippet, shown below.

<html>
    <head>
        <script>
                var div, container = document.getElementById("container")
                for(var i=0;i<5;i++){
                    div = document.createElement("div");
                    div.onclick = function() { 
                        alert("This is a box #"+i);
                    };
                    container.appendChild(div);
                }
            </script>

    </head>
    <body>
        <div id="container"></div>
    </body>
 </html>

https://codepen.io/pcwanderer/pen/MMEREr

Looking at the error in the console for the above code.

Since the document.getElementById is returning a null and as null does not have a attribute named appendChild, therefore a error is thrown. To solve the issue see the code below.

<html>
    <head>
        <style>
        #container{
            height: 200px;
            width: 700px;
            background-color: red;
            margin: 10px;
        }


        div{
            height: 100px;
            width: 100px;
            background-color: purple;
            margin: 20px;
            display: inline-block;
        }
        </style>
    </head>
    <body>
        <div id="container"></div>
        <script>
                var div, container = document.getElementById("container")
                for(let i=0;i<5;i++){
                    div = document.createElement("div");
                    div.onclick = function() { 
                        alert("This is a box #"+i);
                    };
                    container.appendChild(div);

You passed an argument to a function which didn't take any. For example:

If you have an Instance of the EditText available at the point in your code where you want add whitespace, then this code below will work. There may be some things to consider, for example the code below may trigger any TextWatcher you have set to this EditText, idk for sure, just saying, but this will work when trying to append blank space like this: " ", hasn't worked.

messageInputBox.dispatchKeyEvent(new KeyEvent(0, 0, 0, KeyEvent.KEYCODE_SPACE, 0, 0, 0, 0,
                        KeyEvent.KEYCODE_ENDCALL));

You'll have to pass the pointer to the vector, not the vector itself. Note the additional '&' here:

found = binarySearch(first, last, search4, &random);

    // Return the path to the destinationFile if the write is successful
    Right(Files.write(destinationFile, fileContent))
  } catch {
    case exception: Exception => Left(exception)
  }

Usage

val filePath = Paths.get("./testDir/file.txt")

write(filePath , "A test") match {
  case Right(pathToWrittenFile) => println(s"Successfully wrote to $pathToWrittenFile")
  case Left(exception) => println(s"Could not write to $filePath. Exception: $exception")
}

You've used integers in the expression 7/10, and integer 7 divided by integer 10 is zero.

What you're expecting is floating point division. Any of the following would evaluate the way you expected:

7.0 / 10
7 / 10.0
7.0 / 10.0
7 / (double) 10

For a very specific reason Type Nullable<int> put your cursor on Nullable and hit F12 - The Metadata provides the reason (Note the struct constraint):

public struct Nullable<T> where T : struct
{
...

Swift 2.0

You can do following thing to get hours and minute from a date :

let dateFromat = NSDateFormatter()
dateFromat.dateFormat = "hh:mm a"
let date = dateFromat.dateFromString(string1) // In your case its string1
print(date) // you will get - 11:59 AM

Previous answer does not seems to handle cases where rootController are UITabBarController or UINavigationController.

Here is the function in swift which works for those cases :

func getCurrentView() -> UIViewController?
{
    if let window = UIApplication.sharedApplication().keyWindow, var currentView: UIViewController = window.rootViewController
    {
        while (currentView.presentedViewController != nil)
        {
            if let presented = currentView.presentedViewController
            {
                currentView = presented
            }
        }

        if currentView is UITabBarController
        {
            if let visible = (currentView as! UITabBarController).selectedViewController
            {
                currentView = visible;
            }
        }

        if currentView is UINavigationController
        {
            if let visible = (currentView as! UINavigationController).visibleViewController
            {
                currentView = visible;
            }
        }

        return currentView
    }

    return nil
}

I was getting the same error message when I tried to change the domain for iframe.src.

For me, the answer was to change the iframe.src to a url on the same domain, but which was actually an html re-direct page to the desired domain. The other domain then showed up in my iframe without any errors.

Worked like a charm.:)

I used custom DTO (interface) to map a native query to - the most flexible approach and refactoring-safe.

The problem I had with this - that surprisingly, the order of fields in the interface and the columns in the query matters. I got it working by ordering interface getters alphabetically and then ordering the columns in the query the same way.

After a long research I build this reg expression. I hope it will help others too.......

url = 'https://google.co.in';
var re = /[a-z0-9-\.]+\.[a-z]{2,4}\/?([^\s<>\#%"\,\{\}\\|\\\^\[\]`]+)?$/;
if (!re.test(url)) { 
 alert("url error");
return false;
}else{
alert('success')
}

if you just need it for db-related stuff, some OR Mappers (e.g. NHibernate) support transactinos out of the box per default.

You can change the row height of the Datagridview in the .cs [Design].

Then click the datagridview Properties.

Look for RowTemplate and expand it,

then type the value in the Height.

I had the same issue as all of our servers run older versions of MySQL. This can be solved by running a PHP script. Save this code to a file and run it entering the database name, user and password and it'll change the collation from utf8mb4/utf8mb4_unicode_ci to utf8/utf8_general_ci

Here is an example using PowerShell 3.0 or 4.0 for -RepeatIndefinitely and up:

# Trigger
$middayTrigger = New-JobTrigger -Daily -At "12:40 AM"
$midNightTrigger = New-JobTrigger -Daily -At "12:00 PM"
$atStartupeveryFiveMinutesTrigger = New-JobTrigger -once -At $(get-date) -RepetitionInterval $([timespan]::FromMinutes("1")) -RepeatIndefinitely

# Options
$option1 = New-ScheduledJobOption –StartIfIdle

$scriptPath1 = 'C:\Path and file name 1.PS1'
$scriptPath2 = "C:\Path and file name 2.PS1"

Register-ScheduledJob -Name ResetProdCache -FilePath $scriptPath1 -Trigger  $middayTrigger,$midNightTrigger -ScheduledJobOption $option1
Register-ScheduledJob -Name TestProdPing -FilePath $scriptPath2 -Trigger $atStartupeveryFiveMinutesTrigger

This is what I recently did for my Data Visualization Application which has a 2008 SQL Database. In this example I am recieving a list returned from a stored procedure:

public List<CumulativeInstrumentsDataRow> GetCumulativeInstrumentLogs(RunLogFilter filter)
    {
        EFDbContext db = new EFDbContext();
        if (filter.SystemFullName == string.Empty)
        {
            filter.SystemFullName = null;
        }
        if (filter.Reconciled == null)
        {
            filter.Reconciled = 1;
        }
        string sql = GetRunLogFilterSQLString("[dbo].[rm_sp_GetCumulativeInstrumentLogs]", filter);
        return db.Database.SqlQuery<CumulativeInstrumentsDataRow>(sql).ToList();
    }

And then this extension method for some formatting in my case:

public string GetRunLogFilterSQLString(string procedureName, RunLogFilter filter)
        {
            return string.Format("EXEC {0} {1},{2}, {3}, {4}", procedureName, filter.SystemFullName == null ? "null" : "\'" + filter.SystemFullName + "\'", filter.MinimumDate == null ? "null" : "\'" + filter.MinimumDate.Value + "\'", filter.MaximumDate == null ? "null" : "\'" + filter.MaximumDate.Value + "\'", +filter.Reconciled == null ? "null" : "\'" + filter.Reconciled + "\'");

        }

If you go to the folder in finder, right click and select "Get Info" you can go to the "Sharing and Permissions" section for the folder and allow "Read & Write" to "everyone"

This is what I do to make symlinks pass with this error. Also brew seems to reset the permissions on the folder also as if you hadn't altered anything

Here it's the answer for those who are looking for a solution in Bootstrap 3(like myself).

The HTML part:

<div class="btn-group">
  <button type="button" class="btn btn-danger">Action</button>
  <button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
    <span class="glyphicon glyphicon-minus"></span>
  </button>
</div>
<div id="demo" class="collapse in">Some dummy text in here.</div>

The js part:

$('.collapse').on('shown.bs.collapse', function(){
$(this).parent().find(".glyphicon-plus").removeClass("glyphicon-plus").addClass("glyphicon-minus");
}).on('hidden.bs.collapse', function(){
$(this).parent().find(".glyphicon-minus").removeClass("glyphicon-minus").addClass("glyphicon-plus");
});

You can and should have the users's password encrypted:

ALTER USER username WITH ENCRYPTED PASSWORD 'password';

I often use the following:

c := b
if a > b {
    c = a
}

basically the same as @Not_a_Golfer's but using type inference.

logger logs to syslog facilities. If you want the message to go to a particular file you have to modify the syslog configuration accordingly. You could add a line like this:

local7.*   -/var/log/mycustomlog

and restart syslog. Then you can log like this:

logger -p local7.info "information message"
logger -p local7.err "error message"

and the messages will appear in the desired logfile with the correct log level.

Without making changes to the syslog configuration you could use logger like this:

logger -s "foo bar" >> /var/log/mycustomlog

That would instruct logger to print the message to STDERR as well (in addition to logging it to syslog), so you could redirect STDERR to a file. However, it would be utterly pointless, because the message is already logged via syslog anyway (with the default priority user.notice).

This should work.

app = angular.module('plunker', [])

app.controller 'MainCtrl', ($scope) ->
  $scope.users = ['bob', 'sean', 'rocky', 'john']
  $scope.test = ->
    console.log $scope.users

HTML:

<input ng-repeat="user in users" ng-model="user" type="text"/>
<input type="button" value="test" ng-click="test()" />

AJAX requests are asynchronous. Your doSomething function is being exectued, the AJAX request is being made but it happens asynchronously; so the remainder of doSomething is executed and the value of status is undefined when it is returned.

Effectively, your code works as follows:

function doSomething(someargums) {
     return status;
}

var response = doSomething();

And then some time later, your AJAX request is completing; but it's already too late

You need to alter your code, and populate the "response" variable in the "success" callback of your AJAX request. You're going to have to delay using the response until the AJAX call has completed.

Where you previously may have had

var response = doSomething();

alert(response);

You should do:

function doSomething() {  
    $.ajax({
           url:'action.php',
           type: "POST",
           data: dataString,
           success: function (txtBack) { 
            alert(txtBack);
           })
    }); 
};

I was needed to solve absolutely the same task. I have divided visually the table using different background colors for different parts. Googling the Internet I've found this page https://support.microsoft.com/kb/2815384. Unfortunately it doesn't solve the issue because ColorIndex refers to some unpredictable value, so if some cells have nuances of one color (for example different values of brightness of the color), the suggested function counts them. The solution below is my fix:

Function CountBgColor(range As range, criteria As range) As Long
    Dim cell As range
    Dim color As Long
    color = criteria.Interior.color
    For Each cell In range
        If cell.Interior.color = color Then
            CountBgColor = CountBgColor + 1
        End If
    Next cell
End Function

You can also check this out. If you are using this method, then use the parse function to get values from Mongo Database:

db.getCollection('user').find({
    createdOn: {
        $gt: ISODate("2020-01-01T00:00:00.000Z"),
        $lt: ISODate("2020-03-01T00:00:00.000Z")
    }
})

This error can happen because some MFC library (eg. mfc120.dll) from which the DLL is dependent is missing in windows/system32 folder.

environment.plst file loads first on MAC so put the path on it.

For 1st time use, use the following command

export PATH=$PATH: /path/to/set

This should be very simple if Google Calendar does not require the *.ics-extension (which will require some URL rewriting in the server).

$ical = "BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//hacksw/handcal//NONSGML v1.0//EN
BEGIN:VEVENT
UID:" . md5(uniqid(mt_rand(), true)) . "@yourhost.test
DTSTAMP:" . gmdate('Ymd').'T'. gmdate('His') . "Z
DTSTART:19970714T170000Z
DTEND:19970715T035959Z
SUMMARY:Bastille Day Party
END:VEVENT
END:VCALENDAR";

//set correct content-type-header
header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: inline; filename=calendar.ics');
echo $ical;
exit;

That's essentially all you need to make a client think that you're serving a iCalendar file, even though there might be some issues regarding caching, text encoding and so on. But you can start experimenting with this simple code.

By pressing one arrow key getch will push three values into the buffer:

• '\033'
• '['
• 'A', 'B', 'C' or 'D'

So the code will be something like this:

if (getch() == '\033') { // if the first value is esc
    getch(); // skip the [
    switch(getch()) { // the real value
        case 'A':
            // code for arrow up
            break;
        case 'B':
            // code for arrow down
            break;
        case 'C':
            // code for arrow right
            break;
        case 'D':
            // code for arrow left
            break;
    }
}

You can use System.currentTimeMillis().

At least in OpenJDK, Date uses this under the covers.

The call in System is to a native JVM method, so we can't say for sure there's no allocation happening under the covers, though it seems unlikely here.

I'm going to add to the answer given before.

It's not a bug in your code or the browser's code. It's the JavaScript code inside the YouTube iframe polls for the extensions it could interoperate with in case they were installed (likely to determine if the extension is installed).

Look at the source of www-embed-player.js (loaded from s.ytimg.com, it's YouTube static files CDN). You'll find the following:

function Wj(a){return"chrome-extension://"+a+"/cast_sender.js"}

I recommend a really great tool:

native unix utils:

• http://unxutils.sourceforge.net/
• http://en.wikipedia.org/wiki/UnxUtils

Just unpack them and put that folder into your PATH environment variable and voila! :)

Works like a charm, and there are much more then just grep ;)

The objects in the std::set are stored as const StudentT. So when you try to call getId() with the const object the compiler detects a problem, mainly you're calling a non-const member function on const object which is not allowed because non-const member functions make NO PROMISE not to modify the object; so the compiler is going to make a safe assumption that getId() might attempt to modify the object but at the same time, it also notices that the object is const; so any attempt to modify the const object should be an error. Hence compiler generates an error message.

The solution is simple: make the functions const as:

int getId() const {
    return id;
}
string getName() const {
    return name;
}

This is necessary because now you can call getId() and getName() on const objects as:

void f(const StudentT & s)
{
     cout << s.getId();   //now okay, but error with your versions
     cout << s.getName(); //now okay, but error with your versions
}

As a sidenote, you should implement operator< as :

inline bool operator< (const StudentT & s1, const StudentT & s2)
{
    return  s1.getId() < s2.getId();
}

Note parameters are now const reference.

Note that there is a difference between a cast to long and a cast to Long. If you cast to long (a primitive value) then it should be automatically boxed to a Long (the reference type that wraps it).

You could alternatively use new to create an instance of Long, initializing it with the int value.

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

Hope So this logic will help some one.

This works: The way it's set up I called it from the immediate pane, but you can easily create a sub() that will call MoveData once for each month, then just invoke the sub.

You may want to add logic to sort your monthly data after it's all been copied

Public Sub MoveData(MonthNumber As Integer, SheetName As String)

Dim sharePoint As Worksheet
Dim Month As Worksheet
Dim spRange As Range
Dim cell As Range

Set sharePoint = Sheets("Sharepoint")
Set Month = Sheets(SheetName)
Set spRange = sharePoint.Range("A2")
Set spRange = sharePoint.Range("A2:" & spRange.End(xlDown).Address)
For Each cell In spRange
    If Format(cell.Value, "MM") = MonthNumber Then
        copyRowTo sharePoint.Range(cell.Row & ":" & cell.Row), Month
    End If
Next cell

End Sub

Sub copyRowTo(rng As Range, ws As Worksheet)
    Dim newRange As Range
    Set newRange = ws.Range("A1")
    If newRange.Offset(1).Value <> "" Then
        Set newRange = newRange.End(xlDown).Offset(1)
        Else
        Set newRange = newRange.Offset(1)
    End If
    rng.Copy
    newRange.PasteSpecial (xlPasteAll)
End Sub

Edit: Other answers are better, see comments.

I solved the same problem this way:

...
render : function () {
  var componentToRender = 'component1Name';
  var componentLookup = {
    component1Name : (<Component1 />),
    component2Name : (<Component2 />),
    ...
  };
  return (<div>
    {componentLookup[componentToRender]}
  </div>);
}
...

This worked for me

$(function() {
    $("#select option").each(function(i){
        alert($(this).text() + " : " + $(this).val());
    });
});

Recommended solution is to install and trust a self-signed certificate (root). Assuming you created your own CA and the hierarchy of the certificated is correct you don't need to change the server trust evaluation. This is recommended because it doesn't require any changes in the code.

1. Generate CA and the certificates (you can use openssl: Generating CA and self-signed certificates.
2. Install root certificate (*.cer file) on the device - you can open it by Safari and it should redirect you to Settings
3. When the certificated is installed, go to Certificate Trust Settings (Settings > General > About > Certificate Trust Settings) as in MattP answer.

If it is not possible then you need to change server trust evaluation.

What is the recommended way to get this done programmatically?

The only possible option is to run ADB command adb shell pm clear package before the test. The biggest problem is that it's kind of headache combining tests execution and shell commands.

However, we (at Mediafe) came with some solution that can work for you on regular unrooted device. All you need to do is to add an annotation. All the rest is done by running simple bash script.

Just add @ClearData annotation before ANY of your tests and tada , ADB clear command will be executed before the test execution.

This is an example of such test:

@Test
@ClearData
public void someTest() {
    // your test
}

The idea is as follows

1. Read all tests by using adb shell am instrument -e log true
2. Build execution plan by parsing the output from (1)
3. Run the execution plan line by line

Using the same idea these are all options you can easily support:

• Clear data
• Clear notification bar
• Parameterize
• Filter and run by tags

Use only annotations. Like this:

@Test
@ClearData
@Tags(tags = {"sanity", "medium"})
@Parameterized.Repeat(count = 3)
public void myTest() throws Exception {
    String param = params[index];
    // ...
}

Bonus! For each failed test:

• Collect Logcat + stacktrace
• Record video (mp4)
• Dump DB (sqlite)
• Dump default shared preferences (xml)
• Collect dumpsys files like: battery, netstats and other.

In general, it's easy to add more options, since the tests are executed one by one from bash script rather than from gradle task.

Hope this answers 6 years question ;)

You should be able to do the following:

MyFragmentClass test = (MyFragmentClass) getSupportFragmentManager().findFragmentByTag("testID");
if (test != null && test.isVisible()) {
     //DO STUFF
}
else {
    //Whatever
}

try:

var myjson = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var newJ= $.parseJSON(myjson);
    alert(newJ.TeamList[0].teamname);

please try this to clean and format your column names:

df.columns = (df.columns.str.strip().str.upper()
              .str.replace(' ', '_')
              .str.replace('(', '')
              .str.replace(')', ''))

when you add a new data set to a geom you need to use the data= argument. Or put the arguments in the proper order mapping=..., data=.... Take a look at the arguments for ?geom_line.

Thus:

p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red") 

Or:

p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red") 

Neither code is always better. They do different things, so they are good at different things.

InvariantCultureIgnoreCase uses comparison rules based on english, but without any regional variations. This is good for a neutral comparison that still takes into account some linguistic aspects.

OrdinalIgnoreCase compares the character codes without cultural aspects. This is good for exact comparisons, like login names, but not for sorting strings with unusual characters like é or ö. This is also faster because there are no extra rules to apply before comparing.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

Here's a simple single threaded sleep based version that drifts, but tries to auto-correct when it detects drift.

NOTE: This will only work if the following 3 reasonable assumptions are met:

1. The time period is much larger than the execution time of the function being executed
2. The function being executed takes approximately the same amount of time on each call
3. The amount of drift between calls is less than a second

-

from datetime import timedelta
from datetime import datetime

def exec_every_n_seconds(n,f):
    first_called=datetime.now()
    f()
    num_calls=1
    drift=timedelta()
    time_period=timedelta(seconds=n)
    while 1:
        time.sleep(n-drift.microseconds/1000000.0)
        current_time = datetime.now()
        f()
        num_calls += 1
        difference = current_time - first_called
        drift = difference - time_period* num_calls
        print "drift=",drift

bash:

LD_LIBRARY_PATH=my_path
sqsub -np $1 /path/to/executable

Similar, in Python:

import os
import subprocess
import sys

os.environ['LD_LIBRARY_PATH'] = "my_path" # visible in this process + all children
subprocess.check_call(['sqsub', '-np', sys.argv[1], '/path/to/executable'],
                      env=dict(os.environ, SQSUB_VAR="visible in this subprocess"))

There are a few alternate ways to figure out the currently used python in Linux is:

1. which python command.
2. command -v python command
3. type python command

Similarly On Windows with Cygwin will also result the same.

kuvivek@HOSTNAME ~
$ which python
/usr/bin/python

kuvivek@HOSTNAME ~
$ whereis python
python: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4        /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gz

kuvivek@HOSTNAME ~
$ which python3
/usr/bin/python3

kuvivek@HOSTNAME ~
$ command -v python
/usr/bin/python

kuvivek@HOSTNAME ~
$ type python
python is hashed (/usr/bin/python)

If you are already in the python shell. Try anyone of these. Note: This is an alternate way. Not the best pythonic way.

>>> import os
>>> os.popen('which python').read()
'/usr/bin/python\n'
>>>
>>> os.popen('type python').read()
'python is /usr/bin/python\n'
>>>
>>> os.popen('command -v python').read()
'/usr/bin/python\n'
>>>
>>>

If you are not sure of the actual path of the python command and is available in your system, Use the following command.

pi@osboxes:~ $ which python
/usr/bin/python
pi@osboxes:~ $ readlink -f $(which python)
/usr/bin/python2.7
pi@osboxes:~ $ 
pi@osboxes:~ $ which python3
/usr/bin/python3
pi@osboxes:~ $ 
pi@osboxes:~ $ readlink -f $(which python3)
/usr/bin/python3.7
pi@osboxes:~ $ 

Given the following tables..

Domain Table
dom_id | dom_url

Review Table
rev_id | rev_dom_from | rev_dom_for

Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.

Select d1.dom_url, d2.dom_id from
review r, domain d1, domain d2
where d1.dom_id = r.rev_dom_from
and d2.dom_id = r.rev_dom_for

If you are still stuck, please be more specific with exactly it is that you don't understand.

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

In the Terminal, type:

$ curl -V

That's a capital V for the version

I want to initialize every single element of the array to some initial value. So if I have an array Dim myArray(300) As Integer of 300 integers, for example, all 300 elements would hold the same initial value (say, the number 13).

Can anyone explain how to do this, without looping? I'd like to do it in one statement if possible.

What do I win?

Sub SuperTest()
   Dim myArray
   myArray = Application.Transpose([index(Row(1:300),)-index(Row(1:300),)+13])
End Sub

Try:

adb shell ip addr show rmnet0

It will return something like that:

3: rmnet0: <UP,LOWER_UP> mtu 1500 qdisc htb state UNKNOWN qlen 1000
    link/[530]
    inet 172.22.1.100/29 scope global rmnet0
    inet6 fc01:abab:cdcd:efe0:8099:af3f:2af2:8bc/64 scope global dynamic
       valid_lft forever preferred_lft forever
    inet6 fe80::8099:af3f:2af2:8bc/64 scope link
       valid_lft forever preferred_lft forever 

This part is your IPV4 assigned by the operator

inet 172.22.1.100

This part is your IPV6 assigned by the operator

inet6 fc01:abab:cdcd:efe0:8099:af3f:2af2:8bc

How if you want to watch a property for a while and then to un-watch it?

Or to watch a library child component property?

You can use the "dynamic watcher":

this.$watch(
 'object.property', //what you want to watch
 (newVal, oldVal) => {
    //execute your code here
 }
)

The $watch returns an unwatch function which will stop watching if it is called.

var unwatch = vm.$watch('a', cb)
// later, teardown the watcher
unwatch()

Also you can use the deep option:

this.$watch(
'someObject', () => {
    //execute your code here
},
{ deep: true }
)

Please make sure to take a look to docs

Set the foreign key as a primary key, and then set the relationship on both primary key fields. That's it! You should see a key sign on both ends of the relationship line. This represents a one to one.

A lot of good solutions and valuable commentaries by known experts from JS community on the topic could be found here. It could be an indicator that it's not that trivial problem as it may seem. I think this is why it could be the source of doubts and uncertainty on the issue.

Fundamental problem here is that in React you're only allowed to mount component to its parent, which is not always the desired behavior. But how to address this issue?

I propose the solution, addressed to fix this issue. More detailed problem definition, src and examples can be found here: https://github.com/fckt/react-layer-stack#rationale

Rationale

react/react-dom comes comes with 2 basic assumptions/ideas:

• every UI is hierarchical naturally. This why we have the idea of components which wrap each other
• react-dom mounts (physically) child component to its parent DOM node by default

The problem is that sometimes the second property isn't what you want in your case. Sometimes you want to mount your component into different physical DOM node and hold logical connection between parent and child at the same time.

Canonical example is Tooltip-like component: at some point of development process you could find that you need to add some description for your UI element: it'll render in fixed layer and should know its coordinates (which are that UI element coord or mouse coords) and at the same time it needs information whether it needs to be shown right now or not, its content and some context from parent components. This example shows that sometimes logical hierarchy isn't match with the physical DOM hierarchy.

Take a look at https://github.com/fckt/react-layer-stack/blob/master/README.md#real-world-usage-example to see the concrete example which is answer to your question:

import { Layer, LayerContext } from 'react-layer-stack'
// ... for each `object` in array of `objects`
  const modalId = 'DeleteObjectConfirmation' + objects[rowIndex].id
  return (
    <Cell {...props}>
        // the layer definition. The content will show up in the LayerStackMountPoint when `show(modalId)` be fired in LayerContext
        <Layer use={[objects[rowIndex], rowIndex]} id={modalId}> {({
            hideMe, // alias for `hide(modalId)`
            index } // useful to know to set zIndex, for example
            , e) => // access to the arguments (click event data in this example)
          <Modal onClick={ hideMe } zIndex={(index + 1) * 1000}>
            <ConfirmationDialog
              title={ 'Delete' }
              message={ "You're about to delete to " + '"' + objects[rowIndex].name + '"' }
              confirmButton={ <Button type="primary">DELETE</Button> }
              onConfirm={ this.handleDeleteObject.bind(this, objects[rowIndex].name, hideMe) } // hide after confirmation
              close={ hideMe } />
          </Modal> }
        </Layer>

        // this is the toggle for Layer with `id === modalId` can be defined everywhere in the components tree
        <LayerContext id={ modalId }> {({showMe}) => // showMe is alias for `show(modalId)`
          <div style={styles.iconOverlay} onClick={ (e) => showMe(e) }> // additional arguments can be passed (like event)
            <Icon type="trash" />
          </div> }
        </LayerContext>
    </Cell>)
// ...

the "file://" url protocol can only be used to locate files in the file system of the local machine. since this html code is interpreted by a browser, the "local machine" is the machine that is running the browser.

if you are getting file not found errors, i suspect it is because the file is not found. however, it could also be a security limitation of the browser. some browsers will not let you reference a filesystem file from a non-filesystem html page. you could try using the file path from the command line on the machine running the browser to confirm that this is a browser limitation and not a legitimate missing file.

Double equals == will always check based on object identity, regardless of the objects' implementation of hashCode or equals. Of course - make sure the object references you are comparing are volatile (in a 1.5+ JVM).

If you really must have the original Object toString result (although it's not the best solution for your example use-case), the Commons Lang library has a method ObjectUtils.identityToString(Object) that will do what you want. From the JavaDoc:

public static java.lang.String identityToString(java.lang.Object object)

Gets the toString that would be produced by Object if a class did not override toString itself. null will return null.

 ObjectUtils.identityToString(null)         = null
 ObjectUtils.identityToString("")           = "java.lang.String@1e23"
 ObjectUtils.identityToString(Boolean.TRUE) = "java.lang.Boolean@7fa"

This way you have more control over the output - i.e - if you wanted the time format to be '4:30 pm' instead of '04:30 P.M.' - you can convert to whatever format you decide you want - and change it later too. Instead of being constrained to some old method that does not allow any flexibility.

and you only need to convert the first 2 digits as the minute and seconds digits are the same in 24 hour time or 12 hour time.

var my_time_conversion_arr = {'01':"01", '02':"02", '03':"03", '04':"04", '05':"05", '06':"06", '07':"07", '08':"08", '09':"09", '10':"10", '11':"11", '12': "12", '13': "1", '14': "2", '15': "3", '16': "4", '17': "5", '18': "6", '19': "7", '20': "8", '21': "9", '22': "10", '23': "11", '00':"12"};

                var AM_or_PM = "";
                var twenty_four_hour_time = "16:30";
                var twenty_four_hour_time_arr = twenty_four_hour_time.split(":");
                var twenty_four_hour_time_first_two_digits = twenty_four_hour_time_arr[0];

                var first_two_twelve_hour_digits_converted = my_time_conversion_arr[twenty_four_hour_time_first_two_digits];

                var time_strng_to_nmbr = parseInt(twenty_four_hour_time_first_two_digits);
                if(time_strng_to_nmbr >12){
                    //alert("GREATER THAN 12");
                    AM_or_PM = "pm";
                }else{
                    AM_or_PM = "am";
                }

                var twelve_hour_time_conversion = first_two_twelve_hour_digits_converted+":"+twenty_four_hour_time_arr[1]+" "+AM_or_PM;

Workable solution:

downloadCSV(data){   
 const newBlob = new Blob([decodeURIComponent(encodeURI(data))], { type: 'text/csv;charset=utf-8;' });

        // IE doesn't allow using a blob object directly as link href
        // instead it is necessary to use msSaveOrOpenBlob
        if (window.navigator && window.navigator.msSaveOrOpenBlob) {
          window.navigator.msSaveOrOpenBlob(newBlob);
          return;
        }

        // For other browsers:
        // Create a link pointing to the ObjectURL containing the blob.
        const fileData = window.URL.createObjectURL(newBlob);

        const link = document.createElement('a');
        link.href = fileData;
        link.download = `Usecase-Unprocessed.csv`;
        // this is necessary as link.click() does not work on the latest firefox
        link.dispatchEvent(new MouseEvent('click', { bubbles: true, cancelable: true, view: window }));

        setTimeout(function () {
          // For Firefox it is necessary to delay revoking the ObjectURL
          window.URL.revokeObjectURL(fileData);
          link.remove();
        }, 5000);
  }

As a one liner using list comprehension and numpy:

[ax.annotate(x[0], (x[1], x[2])) for x in np.array([n,z,y]).T]

setup is ditto to Rutger's answer.

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

If you're wanting this as a script, the following Bash script should do what you want (plus tell you when the file already exists):

#!/bin/bash
if [ -e $1 ]; then
  echo "File $1 already exists!"
else
  echo >> $1
fi

If you don't want the "already exists" message, you can use:

#!/bin/bash
if [ ! -e $1 ]; then
  echo >> $1
fi

Edit about using:

Save whichever version with a name you like, let's say "create_file" (quotes mine, you don't want them in the file name). Then, to make the file executatble, at a command prompt do:

chmod u+x create_file

Put the file in a directory in your path, then use it with:

create_file NAME_OF_NEW_FILE

The $1 is a special shell variable which takes the first argument on the command line after the program name; i.e. $1 will pick up NAME_OF_NEW_FILE in the above usage example.

main.cpp doesn't have to know what is in class.cpp. It just has to know the declarations of the functions/classes that it goes to use, and these declarations are in class.h.

The linker links between the places where the functions/classes declared in class.h are used and their implementations in class.cpp

The easy way is by using sprintf. I know others have suggested itoa, but a) it isn't part of the standard library, and b) sprintf gives you formatting options that itoa doesn't.

1. Open Developer Command prompt.
2. type

Actually you can use a switch statement with Strings in Java...unfortunately this is a new feature of Java 7, and most people are not using Java 7 yet because it's so new.

For usages of Write-Host, PSScriptAnalyzer produces the following diagnostic:

Avoid using Write-Host because it might not work in all hosts, does not work when there is no host, and (prior to PS 5.0) cannot be suppressed, captured, or redirected. Instead, use Write-Output, Write-Verbose, or Write-Information.

See the documentation behind that rule for more information. Excerpts for posterity:

The use of Write-Host is greatly discouraged unless in the use of commands with the Show verb. The Show verb explicitly means "show on the screen, with no other possibilities".

Commands with the Show verb do not have this check applied.

Jeffrey Snover has a blog post Write-Host Considered Harmful in which he claims Write-Host is almost always the wrong thing to do because it interferes with automation and provides more explanation behind the diagnostic, however the above is a good summary.

Run commands below, in this order:

brew update
brew doctor
brew upgrade node

Now you have installed updated version of node, and it's probably not linked. If it's not, then just type: brew link node or brew link --overwrite node

Haha, oh boy, I figured it out. Somehow, someway, I did not install the Database Engine when I installed SQL Server 2008. I have no idea how I missed that, but that's what happened.
