this is my solution when we want to calculate a date given year, week number and day of the week.

int Year = 2014;
int Week = 48;
int DayOfWeek = 4;

DateTime FecIni = new DateTime(Year, 1, 1);
FecIni = FecIni.AddDays(7 * (Week - 1));
if ((int)FecIni.DayOfWeek > DayOfWeek)
{
    while ((int)FecIni.DayOfWeek != DayOfWeek) FecIni = FecIni.AddDays(-1);
}
else
{
    while ((int)FecIni.DayOfWeek != DayOfWeek) FecIni = FecIni.AddDays(1);
}

best solution:

echo parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);

No need to include your http://domain.com in your if you're submitting a form to the same domain.

I used this:

$('.nav-list li.active').removeClass('active');
$(this).parent().addClass('active');

Since the active class is in the <li> element and what is clicked is the <a> element, the first line removes .active from all <li> and the second one (again, $(this) represents <a> which is the clicked element) adds .active to the direct parent, which is <li>.

    byte[] bytes = {-1, 0, 1, 2, 3 };
    StringBuilder sb = new StringBuilder();
    for (byte b : bytes) {
        sb.append(String.format("%02X ", b));
    }
    System.out.println(sb.toString());
    // prints "FF 00 01 02 03 "

    • Flag '0' - The result will be zero-padded
    • Width 2

Looking at the text of the question, it's also possible that this is what is requested:

    String[] arr = {"-1", "0", "10", "20" };
    for (int i = 0; i < arr.length; i++) {
        arr[i] = String.format("%02x", Byte.parseByte(arr[i]));
    }
    System.out.println(java.util.Arrays.toString(arr));
    // prints "[ff, 00, 0a, 14]"

Several answers here uses Integer.toHexString(int); this is doable, but with some caveats. Since the parameter is an int, a widening primitive conversion is performed to the byte argument, which involves sign extension.

    byte b = -1;
    System.out.println(Integer.toHexString(b));
    // prints "ffffffff"

The 8-bit byte, which is signed in Java, is sign-extended to a 32-bit int. To effectively undo this sign extension, one can mask the byte with 0xFF.

    byte b = -1;
    System.out.println(Integer.toHexString(b & 0xFF));
    // prints "ff"

Another issue with using toHexString is that it doesn't pad with zeroes:

    byte b = 10;
    System.out.println(Integer.toHexString(b & 0xFF));
    // prints "a"

Both factors combined should make the String.format solution more preferrable.

Ruby will not allow this as valid syntax:

false || raise "Error"

However this is valid:

false or raise "Error"

You can make the first work, with () but using or is the correct method.

false || (raise "Error")

Debug and Release are just labels for different solution configurations. You can add others if you want. A project I once worked on had one called "Debug Internal" which was used to turn on the in-house editing features of the application. You can see this if you go to Configuration Manager... (it's on the Build menu). You can find more information on MSDN Library under Configuration Manager Dialog Box.

Each solution configuration then consists of a bunch of project configurations. Again, these are just labels, this time for a collection of settings for your project. For example, our C++ library projects have project configurations called "Debug", "Debug_Unicode", "Debug_MT", etc.

The available settings depend on what type of project you're building. For a .NET project, it's a fairly small set: #defines and a few other things. For a C++ project, you get a much bigger variety of things to tweak.

In general, though, you'll use "Debug" when you want your project to be built with the optimiser turned off, and when you want full debugging/symbol information included in your build (in the .PDB file, usually). You'll use "Release" when you want the optimiser turned on, and when you don't want full debugging information included.

An alternative is to use

The term 'slug' comes from the world of newspaper production.

It's an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the "printing presses", this is the name it is referenced by, e.g., "Have you fixed those errors in the 'kate-and-william' story?".

Some systems (such as Django) use the slug as part of the URL to locate the story, an example being www.mysite.com/archives/kate-and-william.

Even Stack Overflow itself does this, with the GEB-ish^(a) self-referential https://stackoverflow.com/questions/427102/what-is-a-slug-in-django/427201#427201, although you can replace the slug with blahblah and it will still find it okay.

It may even date back earlier than that, since screenplays had "slug lines" at the start of each scene, which basically sets the background for that scene (where, when, and so on). It's very similar in that it's a precis or preamble of what follows.

On a Linotype machine, a slug was a single line piece of metal which was created from the individual letter forms. By making a single slug for the whole line, this greatly improved on the old character-by-character compositing.

Although the following is pure conjecture, an early meaning of slug was for a counterfeit coin (which would have to be pressed somehow). I could envisage that usage being transformed to the printing term (since the slug had to be pressed using the original characters) and from there, changing from the 'piece of metal' definition to the 'story summary' definition. From there, it's a short step from proper printing to the online world.

The behaviour comes from the fact that in Python prior to version 3 bytes was just an alias for str. In Python3.x bytes is an immutable version of bytearray - completely new type, not backwards compatible.

DECLARE @intFlag INT
SET @intFlag = 1
WHILE (@intFlag <=5) 
BEGIN
    PRINT @intFlag
    SET @intFlag = @intFlag + 1

You can call the method getBoundingClientRect() on a reference to the element. Then you can examine the top, left, right and/or bottom properties...

var offsets = document.getElementById('11a').getBoundingClientRect();
var top = offsets.top;
var left = offsets.left;

If using jQuery, you can use the more succinct code...

var offsets = $('#11a').offset();
var top = offsets.top;
var left = offsets.left;

Easiest way is to hit up the information_schemas...

SELECT *
FROM information_schema.Tables
WHERE [Table_Name]='????'

SELECT *
FROM information_schema.Views
WHERE [Table_Name]='????'

SELECT *
FROM information_schema.Routines
WHERE [Routine_Name]='????'

The self answer given by MagngooSasa did the trick, but for anyone else trying to understand the answer, here are a few bit more details:

When developing Cordova apps with Visual Studio, I tried to import a remote JavaScript file [located here http://Guess.What.com/MyScript.js], but I have the error mentioned in the title.

Here is the meta tag before, in the index.html file of the project:

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">

Here is the corrected meta tag, to allow importing a remote script:

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *;**script-src 'self' http://onlineerp.solution.quebec 'unsafe-inline' 'unsafe-eval';** ">

And no more error!

Hilite doesn't seem to be mentioned yet in the answers, so: Hilite supports lots of languages (20+), can be used online also via API, and is on Github (so you can clone, modify, and run it on your own if you don't trust the online service). The online version can also be adjusted to one's needs via CSS rules.

I just found it some minutes ago since I needed a tool for copying xQuery into Word, but couldn't find a proper tool for doing so. The source program is baseX and for some reason, its formatting could not be transmitted to Word (also not via Keep format etc. when pasting). Also, many of the given answers are now, i.e. 06/2019, not working anymore or do not support xQuery. Hilite, however, did the job quite well.

Edit: a code block is not part of the result, unfortunatelly, just the highlighting. Nevertheless, it's better than nothing and adjusting the result by adding a block around is still less work than formating every single line by hand

Use the HTML

<div id="full-size">
    <div id="wrapper">
        Your content goes here.
    </div>
</div>

and use the CSS:

html, body {margin:0;padding:0;height:100%;}
#full-size {
    height:100%;
    width:100%;
    position:absolute;
    top:0;
    left:0;
    overflow:hidden;
}
#wrapper {
    /*You can add padding and margins here.*/
    padding:0;
    margin:0;
}

Make sure that the HTML is in the root element.

Hope this helps!

Just put this blur view on the imageView. Here is an example in Objective-C:

UIVisualEffect *blurEffect;
blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *visualEffectView;
visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

visualEffectView.frame = imageView.bounds;
[imageView addSubview:visualEffectView];

and Swift:

var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light))    

visualEffectView.frame = imageView.bounds

imageView.addSubview(visualEffectView)

Here's something I came up with after applying a few principles other SO posts, including Aaron's link:

AnnotationPin *myAnnotation = (AnnotationPin *)annotation;

self = [super initWithAnnotation:myAnnotation reuseIdentifier:reuseIdentifier];
self.backgroundColor = [UIColor greenColor];
self.frame = CGRectMake(0,0,30,30);
imageView = [[UIImageView alloc] initWithImage:myAnnotation.THEIMAGE];
imageView.frame = CGRectMake(3,3,20,20);
imageView.layer.masksToBounds = NO;
[self addSubview:imageView];
[imageView release];

CGSize titleSize = [myAnnotation.THETEXT sizeWithFont:[UIFont systemFontOfSize:12]];
CGRect newFrame = self.frame;
newFrame.size.height = titleSize.height + 12;
newFrame.size.width = titleSize.width + 32;
self.frame = newFrame;
self.layer.borderColor = [UIColor colorWithRed:0 green:.3 blue:0 alpha:1.0f].CGColor;
self.layer.borderWidth = 3.0;
        
UILabel *infoLabel = [[UILabel alloc] initWithFrame:CGRectMake(26,5,newFrame.size.width-32,newFrame.size.height-12)];
infoLabel.text = myAnnotation.title;
infoLabel.backgroundColor = [UIColor clearColor];
infoLabel.textColor = [UIColor blackColor];
infoLabel.textAlignment = UITextAlignmentCenter;
infoLabel.font = [UIFont systemFontOfSize:12];

[self addSubview:infoLabel];
[infoLabel release];

In this example, I'm adding a custom pin to a MKAnnotation class that resizes a UILabel according to the text size. It also adds an image on the left side of the view, so you see some of the code managing the proper spacing to handle the image and padding.

The key is to use CGSize titleSize = [myAnnotation.THETEXT sizeWithFont:[UIFont systemFontOfSize:12]]; and then redefine the view's dimensions. You can apply this logic to any view.

Although Aaron's answer works for some, it didn't work for me. This is a far more detailed explanation that you should try immediately before going anywhere else if you want a more dynamic view with an image and resizable UILabel. I already did all the work for you!!

Updated

getExternalStoragePublicDirectory() is deprecated.

To get the download folder from a Fragment,

val downloadFolder = requireContext().getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS)

From an Activity,

val downloadFolder = getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS)

downloadFolder.listFiles() will list the Files.

downloadFolder?.path will give you the String path of the download folder.

An alternative is to call the pip module by using python2.7, as below:

python2.7 -m pip <commands>

For example, you could run python2.7 -m pip install <package> to install your favorite python modules. Here is a reference: https://stackoverflow.com/a/50017310/4256346.

In case the pip module has not yet been installed for this version of python, you can run the following:

python2.7 -m ensurepip

Running this command will "bootstrap the pip installer". Note that running this may require administrative privileges (i.e. sudo). Here is a reference: https://docs.python.org/2.7/library/ensurepip.html and another reference https://stackoverflow.com/a/46631019/4256346.

The following regex extract anything between the parenthesis:

PS> $prog = [regex]::match($s,'\(([^\)]+)\)').Groups[1].Value
PS> $prog
SUB RAD MSD 50R III


Explanation (created with RegexBuddy)

Match the character '(' literally «\(»
Match the regular expression below and capture its match into backreference number 1 «([^\)]+)»
   Match any character that is NOT a ) character «[^\)]+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
Match the character ')' literally «\)»

I do not know why you are defining the parameter outside the script. That is unnecessary. Your callback function will be called with the return data as a parameter automatically. It is very possible to define your callback outside the sucess: i.e.

function getData() {
    $.ajax({
        url : 'example.com',
        type: 'GET',
        success : handleData
    })
}

function handleData(data) {
    alert(data);
    //do some stuff
}

the handleData function will be called and the parameter passed to it by the ajax function.

Contrary to Martin's answer, casting to int (or ignoring the warning) isn't always safe even if you know your array doesn't have more than 2^31-1 elements. Not when compiling for 64-bit.

For example:

NSArray *array = @[@"a", @"b", @"c"];

int i = (int) [array indexOfObject:@"d"];
// indexOfObject returned NSNotFound, which is NSIntegerMax, which is LONG_MAX in 64 bit.
// We cast this to int and got -1.
// But -1 != NSNotFound. Trouble ahead!

if (i == NSNotFound) {
    // thought we'd get here, but we don't
    NSLog(@"it's not here");
}
else {
    // this is what actually happens
    NSLog(@"it's here: %d", i);

    // **** crash horribly ****
    NSLog(@"the object is %@", array[i]);
}

try this code

     Calendar cal1 = new GregorianCalendar();
     Calendar cal2 = new GregorianCalendar();

     SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyy");

     Date date = sdf.parse("your first date");
     cal1.setTime(date)
     date = sdf.parse("your second date");
     cal2.setTime(date);

    //cal1.set(2008, 8, 1); 
     //cal2.set(2008, 9, 31);
     System.out.println("Days= "+daysBetween(cal1.getTime(),cal2.getTime()));

this function

     public int daysBetween(Date d1, Date d2){
             return (int)( (d2.getTime() - d1.getTime()) / (1000 * 60 * 60 * 24));
     }

First you need to get the counts for each category, i.e. how many Bads and Goods and so on are there for each group (Food, Music, People). This would be done like so:

raw <- read.csv("http://pastebin.com/raw.php?i=L8cEKcxS",sep=",")
raw[,2]<-factor(raw[,2],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,3]<-factor(raw[,3],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,4]<-factor(raw[,4],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)

raw=raw[,c(2,3,4)] # getting rid of the "people" variable as I see no use for it

freq=table(col(raw), as.matrix(raw)) # get the counts of each factor level

Then you need to create a data frame out of it, melt it and plot it:

Names=c("Food","Music","People")     # create list of names
data=data.frame(cbind(freq),Names)   # combine them into a data frame
data=data[,c(5,3,1,2,4)]             # sort columns

# melt the data frame for plotting
data.m <- melt(data, id.vars='Names')

# plot everything
ggplot(data.m, aes(Names, value)) +   
  geom_bar(aes(fill = variable), position = "dodge", stat="identity")

Is this what you're after?

To clarify a little bit, in ggplot multiple grouping bar you had a data frame that looked like this:

> head(df)
  ID Type Annee X1PCE X2PCE X3PCE X4PCE X5PCE X6PCE
1  1    A  1980   450   338   154    36    13     9
2  2    A  2000   288   407   212    54    16    23
3  3    A  2020   196   434   246    68    19    36
4  4    B  1980   111   326   441    90    21    11
5  5    B  2000    63   298   443   133    42    21
6  6    B  2020    36   257   462   162    55    30

Since you have numerical values in columns 4-9, which would later be plotted on the y axis, this can be easily transformed with reshape and plotted.

For our current data set, we needed something similar, so we used freq=table(col(raw), as.matrix(raw)) to get this:

> data
   Names Very.Bad Bad Good Very.Good
1   Food        7   6    5         2
2  Music        5   5    7         3
3 People        6   3    7         4

Just imagine you have Very.Bad, Bad, Good and so on instead of X1PCE, X2PCE, X3PCE. See the similarity? But we needed to create such structure first. Hence the freq=table(col(raw), as.matrix(raw)).

Should work in all cases:

SELECT regexp_replace(0.1234, '^(-?)([.,])', '\10\2') FROM dual

You can define environment variables in the crontab itself when running crontab -e from the command line.

LANG=nb_NO.UTF-8
LC_ALL=nb_NO.UTF-8
# m h  dom mon dow   command

* * * * * sleep 5s && echo "yo"

This feature is only available to certain implementations of cron. Ubuntu and Debian currently use vixie-cron which allows these to be declared in the crontab file (also GNU mcron).

Archlinux and RedHat use cronie which does not allow environment variables to be declared and will throw syntax errors in the cron.log. Workaround can be done per-entry:

# m h  dom mon dow   command
* * * * * export LC_ALL=nb_NO.UTF-8; sleep 5s && echo "yo"

Simple in two line

1. Go to "Tools" -> "Options" -> "Environment" -> "General" tab,
2. Change "Theme" to dark

In my case here, I had several .lock files in several directories that I needed to remove. I ran the following and it worked without having to go into each directory to remove them:

git rm -r --cached **/*.lock

Doing this went into each folder under the 'root' of where I was at and excluded all files that matched the pattern.

Hope this helps others!

document.getElementById("placehere").appendChild(elem);

not

document.getElementById("placehere").appendChild("elem");

and use the below to set the source

elem.src = 'images/hydrangeas.jpg';

When the user wishes to exit all open activities, they should press a button which loads the first Activity that runs when your app starts, in my case "LoginActivity".

Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code clears all the activities except for LoginActivity. LoginActivity is the first activity that is brought up when the user runs the program. Then put this code inside the LoginActivity's onCreate, to signal when it should self destruct when the 'Exit' message is passed.

    if (getIntent().getBooleanExtra("EXIT", false)) {
         finish();
    }

The answer you get to this question from the Android platform is: "Don't make an exit button. Finish activities the user no longer wants, and the Activity manager will clean them up as it sees fit."

<!-- File input (hidden) -->
<input type="file" id="file1" style="display:none"/>    

<!-- Trigger button -->
<a href="javascript:void(0)" onClick="openSelect('#file1')">

<script type="text/javascript">                            
function openSelect(file)
{
  $(file).trigger('click');
}
</script>

Form.TopMost will work unless the other program is creating topmost windows.

There is no way to create a window that is not covered by new topmost windows of another process. Raymond Chen explained why.

I had the same problem even though openssl was enabled. The issue was that the Composer installer was looking at this config file:

C:\wamp\bin\php\php5.4.3\php.ini

But the config file that's loaded is actually here:

C:\wamp\bin\apache\apache2.2.22\bin\php.ini

So I just had to uncomment it in the first php.ini file and that did the trick. This is how WAMP was installed on my machine by default. I didn't go changing anything, so this will probably happen to others as well. This is basically the same as Augie Gardner's answer above, but I just wanted to point out that you might have two php.ini files.

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

= (MsValueCellReference / 86400000) + DATE(1970,1,1)

Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss gives me a date and time of 19/04/2010 08:16:11

There is element.classList in the DOM API that works for both HTML and SVG elements. No need for jQuery SVG plugin or even jQuery.

$(".jimmy").click(function() {
    this.classList.add("clicked");
});

CSS

overflow-y: scroll;

See it on jsFiddle.

Notice if you remove the -y from the overflow-y property, the horizontal scroll bar is shown.

For me the solution was to create the file .babelrc with this content:

{
  "presets": ["react", "es2015", "stage-1"]
}

$.fn.blink = function(times, duration) {
    times = times || 2;
    while (times--) {
        this.fadeTo(duration, 0).fadeTo(duration, 1);
    }
    return this;
};

I also had the same problem. I used next way:

1.Added settings.xml file (~/.m2/settings.xml) with next content

<proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>qq-proxya</host>
      <port>8080</port>
      <username>user</username>
      <password>passw</password>
      <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
    </proxy>
  </proxies>

3. Using cmd go to folder with my project and wrote mvn clean and after that mvn install !

4. After that updated project in the Eclipse(Alt + F5) or right click on project -> Maven -> Update project

P.S. after that, when I add new dependency to my project I have to compile project using cmd(mvn compile). Because if I do it using eclipse plugin, I get error connecting with proxy connection.

that worked for me after clearing selection, BeginEdit and change the girdview rows and end the Edit Mode.

 if (dgvDetails.RowCount > 0)
                    {
                        dgvDetails.ClearSelection(); 
                        dgvDetails.BeginEdit(true); 
                      
                        foreach (DataGridViewRow dgvr in dgvDetails.Rows)
                        {
                            dgvr.Cells["cellName"].Value = true;
                        }
                        dgvDetails.EndEdit();
                    }

My problem occurs when I try to open https. I don't use SSL.

It's Tomcat bug.

Today 12/02/2017 newest official version from Debian repositories is Tomcat 8.0.14

Solution is to download from official site and install newest package of Tomcat 8, 8.5, 9 or upgrade to newest version(8.5.x) from jessie-backports

Debian 8

Add to /etc/apt/sources.list

deb http://ftp.debian.org/debian jessie-backports main

Then update and install Tomcat from jessie-backports

sudo apt-get update && sudo apt-get -t jessie-backports install tomcat8

What suited my purpose was to create a div that was always bounded within the overall browser window by a fixed amount.

What worked, at least on firefox, was this

<div style="position: absolute; top: 127px; left: 75px;right: 75px; bottom: 50px;">

Insofar as the actual window is not forced into scrolling, the div preserves its boundaries to the window edge during all re-sizing.

Hope this saves someone some time.

Two likely definitions:

• getActivity() in a Fragment returns the Activity the Fragment is currently associated with. (see http://developer.android.com/reference/android/app/Fragment.html#getActivity()).
• getActivity() is user-defined.

The most intuitive way of doing this without using literals or regular expressions:

yourString.replaceAll(" ","");

If you want to change the card background color, use:

app:cardBackgroundColor="@somecolor"

like this:

<android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardBackgroundColor="@color/white">

</android.support.v7.widget.CardView>

Edit: As pointed by @imposible, you need to include

xmlns:app="http://schemas.android.com/apk/res-auto"

in your root XML tag in order to make this snippet function

On non-simple http requests your browser will send a "preflight" request (an OPTIONS method request) first in order to determine what the site in question considers safe information to send (see here for the cross-origin policy spec about this). One of the relevant headers that the host can set in a preflight response is Access-Control-Allow-Headers. If any of the headers you want to send were not listed in either the spec's list of whitelisted headers or the server's preflight response, then the browser will refuse to send your request.

In your case, you're trying to send an Authorization header, which is not considered one of the universally safe to send headers. The browser then sends a preflight request to ask the server whether it should send that header. The server is either sending an empty Access-Control-Allow-Headers header (which is considered to mean "don't allow any extra headers") or it's sending a header which doesn't include Authorization in its list of allowed headers. Because of this, the browser is not going to send your request and instead chooses to notify you by throwing an error.

Any Javascript workaround you find that lets you send this request anyways should be considered a bug as it is against the cross origin request policy your browser is trying to enforce for your own safety.

tl;dr - If you'd like to send Authorization headers, your server had better be configured to allow it. Set your server up so it responds to an OPTIONS request at that url with an Access-Control-Allow-Headers: Authorization header.

Sometimes this could happen during service deletion via PowerShell remote session script, especially when you are trying to delete service several times. In this case, try to recreate a session before the deletion:

Remove-PSSession -Session $session
$newSession = New-PSSession -ComputerName $Name  -Credential $creds -ErrorAction Stop
Enter-PSSession $newSession

In my case i wrote comment in place of Component by mistake

I just wrote this.

import React, { Component } from 'react';

  class Something extends Component{
      render() {
          return();
     }
  }

Instead of this.

import React, { Component } from 'react';

  class Something extends comment{
      render() {
          return();
     }
  }

it's not a big deal but for a beginner like me it's really confusing. I hope this will be helpfull.

Inspired by Radek and Spencer... On Rails 4(.0.2 - Ruby 2.1.0 ), I was able to append this to config/boot.rb:

# config/boot.rb

# ...existing code

require 'rails/commands/server'

module Rails
  # Override default development
  # Server port
  class Server
    def default_options
      super.merge(Port: 3100)
    end
  end
end

All other configuration in default_options are still set, and command-line switches still override defaults.

So to put it all together by using malloc():

int main(int argc, char** argv) {
    typedef struct{
        char* firstName;
        char* lastName;
        int day;
        int month;
        int year;

    }STUDENT;

    int numStudents=3;
    int x;
    STUDENT* students = malloc(numStudents * sizeof *students);
    for (x = 0; x < numStudents; x++){
        students[x].firstName=(char*)malloc(sizeof(char*));
        scanf("%s",students[x].firstName);
        students[x].lastName=(char*)malloc(sizeof(char*));
        scanf("%s",students[x].lastName);
        scanf("%d",&students[x].day);
        scanf("%d",&students[x].month);
        scanf("%d",&students[x].year);
    }

    for (x = 0; x < numStudents; x++)
        printf("first name: %s, surname: %s, day: %d, month: %d, year: %d\n",students[x].firstName,students[x].lastName,students[x].day,students[x].month,students[x].year);

    return (EXIT_SUCCESS);
}

A functional requirement describes what a software system should do, while non-functional requirements place constraints on how the system will do so.

Let me elaborate.

An example of a functional requirement would be:

• A system must send an email whenever a certain condition is met (e.g. an order is placed, a customer signs up, etc).

A related non-functional requirement for the system may be:

• Emails should be sent with a latency of no greater than 12 hours from such an activity.

The functional requirement is describing the behavior of the system as it relates to the system's functionality. The non-functional requirement elaborates a performance characteristic of the system.

Typically non-functional requirements fall into areas such as:

• Accessibility
• Capacity, current and forecast
• Compliance
• Documentation
• Disaster recovery
• Efficiency
• Effectiveness
• Extensibility
• Fault tolerance
• Interoperability
• Maintainability
• Privacy
• Portability
• Quality
• Reliability
• Resilience
• Response time
• Robustness
• Scalability
• Security
• Stability
• Supportability
• Testability

A more complete list is available at Wikipedia's entry for non-functional requirements.

Non-functional requirements are sometimes defined in terms of metrics (i.e. something that can be measured about the system) to make them more tangible. Non-functional requirements may also describe aspects of the system that don't relate to its execution, but rather to its evolution over time (e.g. maintainability, extensibility, documentation, etc.).

It's because there is no long in javascript.

You should do it in componentDidMount and refs callback instead. Something like this

componentDidMount(){
   this.nameInput.focus(); 
}

class App extends React.Component{_x000D_
  componentDidMount(){_x000D_
    this.nameInput.focus();_x000D_
  }_x000D_
  render() {_x000D_
    return(_x000D_
      <div>_x000D_
        <input _x000D_
          defaultValue="Won't focus" _x000D_
        />_x000D_
        <input _x000D_
          ref={(input) => { this.nameInput = input; }} _x000D_
          defaultValue="will focus"_x000D_
        />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
}_x000D_
    _x000D_
ReactDOM.render(<App />, document.getElementById('app'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.3.1/react.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.3.1/react-dom.js"></script>_x000D_
<div id="app"></div>

Number of a columns in the result set you can get with code (as DB is used PostgreSQL):

//load the driver for PostgreSQL
Class.forName("org.postgresql.Driver");

String url = "jdbc:postgresql://localhost/test";
Properties props = new Properties();
props.setProperty("user","mydbuser");
props.setProperty("password","mydbpass");
Connection conn = DriverManager.getConnection(url, props);

//create statement
Statement stat = conn.createStatement();

//obtain a result set
ResultSet rs = stat.executeQuery("SELECT c1, c2, c3, c4, c5 FROM MY_TABLE");

//from result set give metadata
ResultSetMetaData rsmd = rs.getMetaData();

//columns count from metadata object
int numOfCols = rsmd.getColumnCount();

But you can get more meta-informations about columns:

for(int i = 1; i <= numOfCols; i++)
{
    System.out.println(rsmd.getColumnName(i));
}

And at least but not least, you can get some info not just about table but about DB too, how to do it you can find here and here.

For Searchview use these code

1. For XML

   <android.support.v7.widget.SearchView

Here's a little method I created for checking that a object is derived from a specific type. Works great for me!

internal static bool IsDerivativeOf(this Type t, Type typeToCompare)
{
    if (t == null) throw new NullReferenceException();
    if (t.BaseType == null) return false;

    if (t.BaseType == typeToCompare) return true;
    else return t.BaseType.IsDerivativeOf(typeToCompare);
}

try to do this command

sudo fuser -k 443/tcp
service nginx restart

The code above will not run in python3 and is less efficient compared to the GCD variants. However, this code is very transparent. It triggered me to create a more compact version:

def imod(a, n):
 c = 1
 while (c % a > 0):
     c += n
 return c // a

Those of you trying to use the following:

window.open('page.html', '_newtab');

should really look at the window.open method.

All you are doing is telling the browser to open a new window NAMED "_newtab" and load page.html into it. Every new page you load will load into that window. However, if a user has their browser set to open new pages in new tabs instead of new windows, it will open a tab. Regardless, it's using the same name for the window or tab.

If you want different pages to open in different windows or tabs you will have to change the NAME of the new window/tab to something different such as:

window.open('page2.html', '_newtab2');

Of course the name for the new window/tab could be any name like page1, page2, page3, etc. instead of _newtab2.

The best way is to use JobIntentService which uses the new JobScheduler for Oreo or the old services if not available.

Declare in your manifest:

<service android:name=".YourService"
         android:permission="android.permission.BIND_JOB_SERVICE"/>

And in your service you have to replace onHandleIntent with onHandleWork:

public class YourService extends JobIntentService {

    public static final int JOB_ID = 1;

    public static void enqueueWork(Context context, Intent work) {
        enqueueWork(context, YourService.class, JOB_ID, work);
    }

    @Override
    protected void onHandleWork(@NonNull Intent intent) {
        // your code
    }

}

Then you start your service with:

YourService.enqueueWork(context, new Intent());

Using Integer.parseIn(String), you can parse string value into integer. Also you need to catch exception in case if input string is not a proper number.

int x = 0;

try {       
    x = Integer.parseInt("100"); // Parse string into number
} catch (NumberFormatException e) {
    e.printStackTrace();
}

Note that the fields must be in the same order. If the Primary Key you are referencing is specified as (Application, ID) then your foreign key must reference (Application, ID) and NOT (ID, Application) as they are seen as two different keys.

Try the sql server management studio (version 2008 or earlier) from Microsoft. Download it from here. Not sure about the license, but it seems to be free if you download the EXPRESS EDITION.

You might also be able to use later editions of SSMS. For 2016, you will need to install an extension.

If you have the option you can copy the sdf file to a different machine which you are allowed to pollute with additional software.

Update: comment from Nick Westgate in nice formatting

The steps are not all that intuitive:

1. Open SQL Server Management Studio, or if it's running select File -> Connect Object Explorer...
2. In the Connect to Server dialog change Server type to SQL Server Compact Edition
3. From the Database file dropdown select < Browse for more...>
4. Open your SDF file.

Addition to most voted answer.

obtainStyledAttributes()

I want to add some words about obtainStyledAttributes() usage, when we create custom view using android:xxx prdefined attributes. Especially when we use TextAppearance.
As was mentioned in "2. Creating constructors", custom view gets AttributeSet on its creation. Main usage we can see in TextView source code (API 16).

final Resources.Theme theme = context.getTheme();

// TextAppearance is inspected first, but let observe it later

TypedArray a = theme.obtainStyledAttributes(
            attrs, com.android.internal.R.styleable.TextView, defStyle, 0);

int n = a.getIndexCount();
for (int i = 0; i < n; i++) 
{
    int attr = a.getIndex(i);
    // huge switch with pattern value=a.getXXX(attr) <=> a.getXXX(a.getIndex(i))
}
a.recycle();

What we can see here?
obtainStyledAttributes(AttributeSet set, int[] attrs, int defStyleAttr, int defStyleRes)
Attribute set is processed by theme according to documentation. Attribute values are compiled step by step. First attributes are filled from theme, then values are replaced by values from style, and finally exact values from XML for special view instance replace others.
Array of requested attributes - com.android.internal.R.styleable.TextView
It is an ordinary array of constants. If we are requesting standard attributes, we can build this array manually.

What is not mentioned in documentation - order of result TypedArray elements.
When custom view is declared in attrs.xml, special constants for attribute indexes are generated. And we can extract values this way: a.getString(R.styleable.MyCustomView_android_text). But for manual int[] there are no constants. I suppose, that getXXXValue(arrayIndex) will work fine.

And other question is: "How we can replace internal constants, and request standard attributes?" We can use android.R.attr.* values.

So if we want to use standard TextAppearance attribute in custom view and read its values in constructor, we can modify code from TextView this way:

ColorStateList textColorApp = null;
int textSize = 15;
int typefaceIndex = -1;
int styleIndex = -1;

Resources.Theme theme = context.getTheme();

TypedArray a = theme.obtainStyledAttributes(attrs, R.styleable.CustomLabel, defStyle, 0);
TypedArray appearance = null;
int apResourceId = a.getResourceId(R.styleable.CustomLabel_android_textAppearance, -1);
a.recycle();
if (apResourceId != -1)
{
    appearance = 
        theme.obtainStyledAttributes(apResourceId, new int[] { android.R.attr.textColor, android.R.attr.textSize, 
            android.R.attr.typeface, android.R.attr.textStyle });
}
if (appearance != null)
{
    textColorApp = appearance.getColorStateList(0);
    textSize = appearance.getDimensionPixelSize(1, textSize);
    typefaceIndex = appearance.getInt(2, -1);
    styleIndex = appearance.getInt(3, -1);

    appearance.recycle();
}

Where CustomLabel is defined:

<declare-styleable name="CustomLabel">
    <!-- Label text. -->
    <attr name="android:text" />
    <!-- Label text color. -->
    <attr name="android:textColor" />
    <!-- Combined text appearance properties. -->
    <attr name="android:textAppearance" />
</declare-styleable>

Maybe, I'm mistaken some way, but Android documentation on obtainStyledAttributes() is very poor.

Extending standard UI component

At the same time we can just extend standard UI component, using all its declared attributes. This approach is not so good, because TextView for instance declares a lot of properties. And it will be impossible to implement full functionality in overriden onMeasure() and onDraw().

But we can sacrifice theoretical wide reusage of custom component. Say "I know exactly what features I will use", and don't share code with anybody.

Then we can implement constructor CustomComponent(Context, AttributeSet, defStyle). After calling super(...) we will have all attributes parsed and available through getter methods.

You can simply use theatol()function:

#include <stdio.h>
#include <stdlib.h>

int main() 
{
    const char *c = "5";
    int d = atol(c);
    printf("%d\n", d);

}

I'm not sure about HQL, but in JPA you just call the query's setParameter with the parameter and collection.

Query q = entityManager.createQuery("SELECT p FROM Peron p WHERE name IN (:names)");
q.setParameter("names", names);

where names is the collection of names you're searching for

Collection<String> names = new ArrayList<String();
names.add("Joe");
names.add("Jane");
names.add("Bob");

functional solution

function applyFilters(data, filters) {
  return data.filter(item =>
    Object.keys(filters)
      .map(keyToFilterOn =>
        item[keyToFilterOn].includes(filters[keyToFilterOn]),
      )
      .reduce((x, y) => x && y, true),
  );
}

this should do the job

applyFilters(users, filter);

For a start the first select has 6 columns and the second has 4 columns. Perhaps make both have the same number of columns (adding nulls?).

Try with pip3:

sudo pip3 install pycrypto

Your current code works, you can try it here: http://jsfiddle.net/s4UyH/

You have something outside the example triggering another .click(), check for other handlers that are also triggering a click event on that element.

You can also use the [NonSerialized] attribute

[Serializable]
public struct MySerializableStruct
{
    [NonSerialized]
    public string hiddenField;
    public string normalField;
}

From the MS docs:

Indicates that a field of a serializable class should not be serialized. This class cannot be inherited.

If you're using Unity for example (this isn't only for Unity) then this works with UnityEngine.JsonUtility

using UnityEngine;

MySerializableStruct mss = new MySerializableStruct 
{ 
    hiddenField = "foo", 
    normalField = "bar" 
};
Debug.Log(JsonUtility.ToJson(mss)); // result: {"normalField":"bar"}

//works in IE, not sure about other browsers...

alert(classes[x].style.cssText);

If you could not found run the command,

CentOS:

# yum install dos2unix*

# dos2unix filename.sh
dos2unix: converting file filename.sh to Unix format ...

Ubuntu / Debian:

# apt-get install dos2unix

In a comment on @paxdiablo's answer, you asked:

"So basically, is it better to use Double than Float?"

That is a complicated question. I will deal with it in two parts

Deciding between double versus float

On the one hand, a double occupies 8 bytes versus 4 bytes for a float. If you have many of them, this may be significant, though it may also have no impact. (Consider the case where the values are in fields or local variables on a 64bit machine, and the JVM aligns them on 64 bit boundaries.) Additionally, floating point arithmetic with double values is typically slower than with float values ... though once again this is hardware dependent.

On the other hand, a double can represent larger (and smaller) numbers than a float and can represent them with more than twice the precision. For the details, refer to Wikipedia.

The tricky question is knowing whether you actually need the extra range and precision of a double. In some cases it is obvious that you need it. In others it is not so obvious. For instance if you are doing calculations such as inverting a matrix or calculating a standard deviation, the extra precision may be critical. On the other hand, in some cases not even double is going to give you enough precision. (And beware of the trap of expecting float and double to give you an exact representation. They won't and they can't!)

There is a branch of mathematics called Numerical Analysis that deals with the effects of rounding error, etc in practical numerical calculations. It used to be a standard part of computer science courses ... back in the 1970's.

Deciding between Double versus Float

For the Double versus Float case, the issues of precision and range are the same as for double versus float, but the relative performance measures will be slightly different.

• A Double (on a 32 bit machine) typically takes 16 bytes + 4 bytes for the reference, compared with 12 + 4 bytes for a Float. Compare this to 8 bytes versus 4 bytes for the double versus float case. So the ratio is 5 to 4 versus 2 to 1.

• Arithmetic involving Double and Float typically involves dereferencing the pointer and creating a new object to hold the result (depending on the circumstances). These extra overheads also affect the ratios in favor of the Double case.

Correctness

Having said all that, the most important thing is correctness, and this typically means getting the most accurate answer. And even if accuracy is not critical, it is usually not wrong to be "too accurate". So, the simple "rule of thumb" is to use double in preference to float, UNLESS there is an overriding performance requirement, AND you have solid evidence that using float will make a difference with respect to that requirement.

I know the question is from 2012, but I found the easiest way ever, and I wanted to share.

HTML:

<div id="parent">
     <div id="child">Content here</div>
</div>

and CSS:

#parent{
     height: 100%;
     display: table;
}    
#child {
     display: table-cell;
     vertical-align: middle; 
}

I use method 3 because it's the most understandable for others (whenever you see an <a> tag, you know it's a link) and when you are part of a team, you have to make simple things ;).

And finally I don't think it's useful and efficient to use JS simply to navigate to an other page.

REM Delete eval folder with licence key and options.xml which contains a reference  to it
for %%I in ("WebStorm", "IntelliJ", "CLion", "Rider", "GoLand", "PhpStorm") do (
  for /d %%a in ("%USERPROFILE%\.%%I*") do (
    rd /s /q "%%a/config/eval"
    del /q "%%a\config\options\other.xml"
  )
)

REM Delete registry key and jetbrains folder (not sure if needet but however)
rmdir /s /q "%APPDATA%\JetBrains"
reg delete "HKEY_CURRENT_USER\Software\JavaSoft" /f

Now rename the file fileName.txt to fileName.bat

Close phpstorm if running. Disconnect internet. Then run the file. Open phpstorm again. If nothing goes wrong you will see the magic.

worst case : If phpstorm still shows "License Expired", at first uninstall and then apply the above technique.

After messing about with some stuff in cron which wasn't instantly compatible I found that the following approach was nice for debugging:

crontab -e

* * * * * /path/to/prog var1 var2 &>>/tmp/cron_debug_log.log

This will run the task once a minute and you can simply look in the /tmp/cron_debug_log.log file to figure out what is going on.

It is not exactly the "fire job" you might be looking for, but this helped me a lot when debugging a script that didn't work in cron at first.

After porting several of my libraries to different projects, and having to constantly be changing the top level (statically named) namespace, I've switched to using this small (open source) helper function for defining namespaces.

global_namespace.Define('startpad.base', function(ns) {
    var Other = ns.Import('startpad.other');
    ....
});

Description of the benefits are at my blog post. You can grab the source code here.

One of the benefits I really like is isolation between modules with respect to load order. You can refer to an external module BEFORE it is loaded. And the object reference you get will be filled in when the code is available.

Given an answer as high voted and views. I did find the answer with mixed of here and other links.

I have a scenario where all patient-related menu is disabled if a patient is not selected. (Refer link - how to disable a li tag using JavaScript)

//css
.disabled{
    pointer-events:none;
    opacity:0.4;
}
// jqvery
$("li a").addClass('disabled');
// remove .disabled when you are done

So rather than write long code, I found an interesting solution via CSS.

$(document).ready(function () {_x000D_
 var PatientId ; _x000D_
 //var PatientId =1;  //remove to test enable i.e. patient selected_x000D_
 if (typeof PatientId == "undefined" || PatientId == "" || PatientId == 0 || PatientId == null) {_x000D_
  console.log(PatientId);_x000D_
  $("#dvHeaderSubMenu a").each(function () {   _x000D_
   $(this).addClass('disabled');_x000D_
  });  _x000D_
  return;_x000D_
 }_x000D_
})

.disabled{_x000D_
    pointer-events:none;_x000D_
    opacity:0.4;_x000D_
}

If you are looking at a Table, a Pivot Table, or something with conditional formatting, you can try:

ActiveCell.DisplayFormat.Interior.Color

This also seems to work just fine on regular cells.

I wanted an "expand/collapse" container with a plus and minus button to open and close it. This uses the standard bootstrap event and has animation. This is BS3.

HTML:

<button id="button" type="button" class="btn btn-primary" 
  data-toggle="collapse" data-target="#demo">
  <span class="glyphicon glyphicon-collapse-down"></span> Show
</button>

<div id="demo" class="collapse">
  <ol class="list-group">
      <li class="list-group-item">Warrior</li>
      <li class="list-group-item">Adventurer</li>
      <li class="list-group-item">Mage</li>
  </ol>
</div>

JS:

$(function(){
  $('#demo').on('hide.bs.collapse', function () {
    $('#button').html('<span class="glyphicon glyphicon-collapse-down"></span> Show');
  })
  $('#demo').on('show.bs.collapse', function () {
    $('#button').html('<span class="glyphicon glyphicon-collapse-up"></span> Hide');
  })
})

Example:

Since "Guid" is not nullable, use "Guid.Empty" as default value.

There are two typical ways of declaring a function. I prefer the second approach.

function function_name {
   command...
} 

or

function_name () {
   command...
} 

To call a function with arguments:

function_name "$arg1" "$arg2"

The function refers to passed arguments by their position (not by name), that is $1, $2, and so forth. $0 is the name of the script itself.

Example:

function_name () {
   echo "Parameter #1 is $1"
}

Also, you need to call your function after it is declared.

#!/usr/bin/env sh

foo 1  # this will fail because foo has not been declared yet.

foo() {
    echo "Parameter #1 is $1"
}

foo 2 # this will work.

Output:

./myScript.sh: line 2: foo: command not found
Parameter #1 is 2

is is generally preferred when comparing arbitrary objects to singletons like None because it is faster and more predictable. is always compares by object identity, whereas what == will do depends on the exact type of the operands and even on their ordering.

This recommendation is supported by PEP 8, which explicitly states that "comparisons to singletons like None should always be done with is or is not, never the equality operators."

You might have an easier time first implementing it with mouse events to prototype.

There are many answers here, including the top, should be used with caution as they do not consider edge cases especially around bounding boxes.

See:

• Touch Events
• Mouse Events

You will need to experiment to catch edge cases and behaviours such as the pointer moving outside of the element before ending.

A swipe is a very basic gesture which is a higher level of interface pointer interaction processing roughly sitting between processing raw events and handwriting recognition.

There's no single exact method for detecting a swipe or a fling though virtually all generally follow a basic principle of detecting a motion across an element with a threshold of distance and speed or velocity. You might simply say that if there is a movement across 65% of the screen size in a given direction within a given time then it is a swipe. Exactly where you draw the line and how you calculate it is up to you.

Some might also look at it from the perspective of momentum in a direction and how far off the screen it has been pushed when the element is released. This is clearer with sticky swipes where the element can be dragged and then on release will either bounce back or fly off the screen as if the elastic broke.

It's probably ideal to try to find a gesture library that you can either port or reuse that's commonly used for consistency. Many of the examples here are excessively simplistic, registering a swipe as the slightest touch in any direction.

Android would be the obvious choice though has the opposite problem, it's overly complex.

Many people appear to have misinterpreted the question as any movement in a direction. A swipe is a broad and relatively brief motion overwhelmingly in a single direction (though may be arced and have certain acceleration properties). A fling is similar though intends to casually propel an item away a fair distance under its own momentum.

The two are sufficiently similar that some libraries might only provide fling or swipe, which can be used interchangeably. On a flat screen it's difficult to truly separate the two gestures and generally speaking people are doing both (swiping the physical screen but flinging the UI element displayed on the screen).

You best option is to not do it yourself. There are already a large number of JavaScript libraries for detecting simple gestures.

Instead of JSONObject , you can use ObjectMapper to convert java object to json string

ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);

If you want to use nc but don't have a version that support -z, try using --send-only:

nc --send-only <IP> <PORT> </dev/null

and with timeout:

nc -w 1 --send-only <IP> <PORT> </dev/null

and without DNS lookup if it's an IP:

nc -n -w 1 --send-only <IP> <PORT> </dev/null

It returns the codes as the -z based on if it can connect or not.

None of these worked for me. So as I compared various app pools with one that worked vs one that didn't, I had to go into Advanced Settings for the App Pool, and set

Enable 32-Bit Applications = true

Then it worked fine!

It is possible. Have a look at JSch.addIdentity(...)

This allows you to use key either as byte array or to read it from file.

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class UserAuthPubKey {
    public static void main(String[] arg) {
        try {
            JSch jsch = new JSch();

            String user = "tjill";
            String host = "192.18.0.246";
            int port = 10022;
            String privateKey = ".ssh/id_rsa";

            jsch.addIdentity(privateKey);
            System.out.println("identity added ");

            Session session = jsch.getSession(user, host, port);
            System.out.println("session created.");

            // disabling StrictHostKeyChecking may help to make connection but makes it insecure
            // see http://stackoverflow.com/questions/30178936/jsch-sftp-security-with-session-setconfigstricthostkeychecking-no

            // session.setConfig(config);

            session.connect();
            System.out.println("session connected.....");

            Channel channel = session.openChannel("sftp");
            channel.setInputStream(System.in);
            channel.setOutputStream(System.out);
            channel.connect();
            System.out.println("shell channel connected....");

            ChannelSftp c = (ChannelSftp) channel;

            String fileName = "test.txt";
            c.put(fileName, "./in/");
            c.exit();
            System.out.println("done");

        } catch (Exception e) {
            System.err.println(e);
        }
    }
}

How about this method:

Set a field in the first object to a new value. If the same field in the second object has the same value, it's probably the same instance. Otherwise, exit as different.

Now set the field in the first object to a different new value. If the same field in the second object has changed to the different value, it's definitely the same instance.

Don't forget to set field in the first object back to it's original value on exit.

Problems?

I use schema and data comparison functionality built into the latest version Microsoft Visual Studio 2015 Community Edition (Free) or Professional / Premium / Ultimate edition. Works like a charm!

Red-Gate's SQL data comparison tool is my second alternative:

My use case is simpler, and fits simply your title but not your further detail.

That is, I want to install a new package which is not yet in my composer.json without updating all the other packages.

The solution here is composer require x/y

The great thing about yyyy-mm-dd date format is that there is no need to extract month() and year(), you can do comparisons directly on strings:

SELECT *
  FROM your_table
  WHERE your_date_column >= '2010-09-01' AND your_date_column <= '2013-08-31';

To write/save

%%writefile myfile.py

• write/save cell contents into myfile.py (use -a to append). Another alias: %%file myfile.py

To run

%run myfile.py

• run myfile.py and output results in the current cell

To load/import

%load myfile.py

• load "import" myfile.py into the current cell

For more magic and help

%lsmagic

• list all the other cool cell magic commands.

%COMMAND-NAME?

• for help on how to use a certain command. i.e. %run?

Note

Beside the cell magic commands, IPython notebook (now Jupyter notebook) is so cool that it allows you to use any unix command right from the cell (this is also equivalent to using the %%bash cell magic command).

To run a unix command from the cell, just precede your command with ! mark. for example:

• !python --version see your python version
• !python myfile.py run myfile.py and output results in the current cell, just like %run (see the difference between !python and %run in the comments below).

Also, see this nbviewer for further explanation with examples. Hope this helps.

You can also combine them I guess:

<!doctype html>
<html ng-app="myApp">
<head>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script src="http://code.angularjs.org/1.1.2/angular.min.js"></script>
    <script type="text/javascript">
        var myApp = angular.module('myApp', []);

        myApp.factory('myService', function() {
            return {
                foo: function() {
                    alert("I'm foo!");
                }
            };
        });

        myApp.run(function($rootScope, myService) {
            $rootScope.appData = myService;
        });

        myApp.controller('MainCtrl', ['$scope', function($scope){

        }]);

    </script>
</head>
<body ng-controller="MainCtrl">
    <button ng-click="appData.foo()">Call foo</button>
</body>
</html>

Note: This was written and accepted back in the Rails 2 days; nowadays grosser's answer is the way to go.

Option 1: Probably the simplest way is to include your helper module in your controller:

class MyController < ApplicationController
  include MyHelper

  def xxxx
    @comments = []
    Comment.find_each do |comment|
      @comments << {:id => comment.id, :html => html_format(comment.content)}
    end
  end
end

Option 2: Or you can declare the helper method as a class function, and use it like so:

MyHelper.html_format(comment.content)

If you want to be able to use it as both an instance function and a class function, you can declare both versions in your helper:

module MyHelper
  def self.html_format(str)
    process(str)
  end

  def html_format(str)
    MyHelper.html_format(str)
  end
end

Hope this helps!

you can get the product name like this

foreach ( $cart_object->cart_contents as  $value ) {
        $_product     = apply_filters( 'woocommerce_cart_item_product', $value['data'] );

        if ( ! $_product->is_visible() ) {
                echo $_product->get_title();
        } else {
                echo $_product->get_title();
        }


     }

I just use the simple nohl below and no plugins are needed.

:nohl

Cause: I have noticed that when I clean my project or clean one of the dependent projects and then hit refresh a few times on the page showing the site then it causes this error. It seems like it tries to load/run a broken/missing DLL project somehow.

Rename the project’s IIS directory to something different and with new name it loads fine (again providing project is built first OK then run otherwise it causes the same issue)

Try This:)

before:-

<servlet>
    <servlet-name>TestServlet</servlet-name>
    <servlet-class>TestServlet</servlet-class>  
</servlet>

After:-

 <servlet>
    <servlet-name>TestServlet</servlet-name>
    <servlet-class>operation.TestServlet</servlet-class>
 </servlet>

Another option is using the overloaded + operator:

>>> l = ['hello','world']
>>> l = ['foo'] + l
>>> l
['foo', 'hello', 'world']

Use onload event to convert image after loading

function loaded(img) {_x000D_
  let c = document.createElement('canvas')_x000D_
  c.getContext('2d').drawImage(img, 0, 0)_x000D_
  msg.innerText= c.toDataURL();_x000D_
}

git log -1 --format="%an %ae%n%cn %ce" a2c25061

The Pretty Formats section of the git show documentation contains

• format:<string>

The format:<string> format allows you to specify which information you want to show. It works a little bit like printf format, with the notable exception that you get a newline with %n instead of \n …

The placeholders are:

• %an: author name
• %ae: author email
• %cn: committer name
• %ce: committer email

One thing that hasn't been explicitly mentioned - the scope feature gives you an option to have the same name for an enum and class method. For instance:

class Test
{
public:
   // these call ProcessCommand() internally
   void TakeSnapshot();
   void RestoreSnapshot();
private:
   enum class Command // wouldn't be possible without 'class'
   {
        TakeSnapshot,
        RestoreSnapshot
   };
   void ProcessCommand(Command cmd); // signal the other thread or whatever
};

In my case it was a file not found, I typed the path to the javascript file incorrectly.

When i inspect the console i found that the version of maven compiler is 2.5.1 but in other side i try to build my project with maven 3.2.2.So after writting the exact version in pom.xml, it works good. Here is the full tag:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.2</version>
  <configuration>
   ....
  <configuration>
</plugin>

Add a border to the regular item, the same color as the background, so that it cannot be seen. That way the item has a border: 1px whether it is being hovered or not.

Call ToString() instead of casting the reader result.

reader[0].ToString();
reader[1].ToString();
// etc...

And if you want to fetch specific data type values (int in your case) try the following:

reader.GetInt32(index);

You can check like this:

int x;
cin >> x;

if (cin.fail()) {
    //Not an int.
}

Furthermore, you can continue to get input until you get an int via:

#include <iostream>



int main() {

    int x;
    std::cin >> x;
    while(std::cin.fail()) {
        std::cout << "Error" << std::endl;
        std::cin.clear();
        std::cin.ignore(256,'\n');
        std::cin >> x;
    }
    std::cout << x << std::endl;

    return 0;
}

EDIT: To address the comment below regarding input like 10abc, one could modify the loop to accept a string as an input. Then check the string for any character not a number and handle that situation accordingly. One needs not clear/ignore the input stream in that situation. Verifying the string is just numbers, convert the string back to an integer. I mean, this was just off the cuff. There might be a better way. This won't work if you're accepting floats/doubles (would have to add '.' in the search string).

#include <iostream>
#include <string>

int main() {

    std::string theInput;
    int inputAsInt;

    std::getline(std::cin, theInput);

    while(std::cin.fail() || std::cin.eof() || theInput.find_first_not_of("0123456789") != std::string::npos) {

        std::cout << "Error" << std::endl;

        if( theInput.find_first_not_of("0123456789") == std::string::npos) {
            std::cin.clear();
            std::cin.ignore(256,'\n');
        }

        std::getline(std::cin, theInput);
    }

    std::string::size_type st;
    inputAsInt = std::stoi(theInput,&st);
    std::cout << inputAsInt << std::endl;
    return 0;
}

put it in between <pre></pre> tags then use this characters 	

it would not work without the <pre></pre> tags

Using Display: table

HTML:

<ul class="my-row">
    <li>1</li>
    <li>2</li>
    <li>3</li>
</ul>

CSS:

ul.my-row {
  display: table;
  width: 100%;
  text-align: center;
}

ul.my-row > li {
  display: table-cell;
}

SCSS:

ul {
  &.my-row {
    display: table;
    width: 100%;
    text-align: center;

    > li {
      display: table-cell;
    }
  } 
}

Work great for me

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

My recommendation for this is to NOT use native btoa strategies—as they don't correctly encode all ArrayBuffer's…

rewrite the DOMs atob() and btoa()

Since DOMStrings are 16-bit-encoded strings, in most browsers calling window.btoa on a Unicode string will cause a Character Out Of Range exception if a character exceeds the range of a 8-bit ASCII-encoded character.

While I have never encountered this exact error, I have found that many of the ArrayBuffer's I have tried to encode have encoded incorrectly.

I would either use MDN recommendation or gist.

• https://github.com/beatgammit/base64-js
• https://gist.github.com/jonleighton/958841

Many answers here. Here is my first consideration.

Without JavaScript, including the possibility Javascript is initially disabled by the user in his browser for security purposes, to be white listed by the user if the user trusts the site, DOM will not be usable because Javascript is off.

Programmatically, you are left with a backend server-side or frontend client-side consideration.

With the backend, you can use common denominator HTTP "User-Agent" request header and/or any possible proprietary HTTP request header issued by the browser to output browser specific HTML stuff.

With the client site, you may want to enforce Javascript to allow you to use DOM. If so, then you probably will want to first use the following in your HTML page:

<noscript>This site requires Javascript. Please turn on Javascript.</noscript>

While we are heading to a day with every web coder will be dependent on Javascript in some way (or not), today, to presume every user has javascript enabled would be design and product development QA mistake.

I've seen far too may sites who end up with a blank page or the site breaks down because it presumed every user has javascript enabled. No. For security purposes, they may have Javascript initially off and some browsers, like Chrome, will allow the user to white list the web site on a domain by domain basis. Edge is the only browser I am aware of where Microsoft made the decision to completely disable the user's ability to turn off Javascript. Edge doesn't offer a white listing concept hence it is one reason I don't personally use Edge.

Using the tag is a simple way to inform the user your site won't work without Javascript. Once the user turns it on and refreshes/reload the page, DOM is now available to use the techniques cited by the thread replies to detect chrome vs safari.

Ironically, I got here because I was updating by platform and google the same basic question; chrome vs sarafi. I didn't know Chrome creates a DOM object named "chrome" which is really all you need to detect "chrome" vs everything else.

var isChrome = typeof(chrome) === "object";

If true, you got Chrome, if false, you got some other browser.

Check to see if Safari create its own DOM object as well, if so, get the object name and do the same thing, for example:

var isSafari = (typeof(safari) === "object");

Hope these tips help.

If your needing/wanting to use the ConfigurationManager class...

You may need to load System.Configuration.ConfigurationManager by Microsoft via NuGet Package Manager

Tools->NuGet Package Manager->Manage NuGet Packages for Solution...

Microsoft Docs

One thing worth noting from the docs...

If your application needs read-only access to its own configuration, we recommend that you use the GetSection(String) method. This method provides access to the cached configuration values for the current application, which has better performance than the Configuration class.

You could also use =COUNTA(A1:A200) which requires no conditions.

From Google Support:

COUNTA counts all values in a dataset, including those which appear more than once and text values (including zero-length strings and whitespace). To count unique values, use COUNTUNIQUE.

Not much documentation on PowerShell loops.

Documentation on loops in PowerShell is plentiful, and you might want to check out the following help topics: about_For, about_ForEach, about_Do, about_While.

foreach($line in Get-Content .\file.txt) {
    if($line -match $regex){
        # Work here
    }
}

Another idiomatic PowerShell solution to your problem is to pipe the lines of the text file to the ForEach-Object cmdlet:

Get-Content .\file.txt | ForEach-Object {
    if($_ -match $regex){
        # Work here
    }
}

Instead of regex matching inside the loop, you could pipe the lines through Where-Object to filter just those you're interested in:

Get-Content .\file.txt | Where-Object {$_ -match $regex} | ForEach-Object {
    # Work here
}

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

You can set max connections using:

set global max_connections = '1 < your number > 100000';

This will set your number of mysql connection unti (Requires SUPER privileges).

That's because you shouldn't do it (at least with an immutable list). If you really really need to append an element to the end of a data structure and this data structure really really needs to be a list and this list really really has to be immutable then do eiher this:

(4 :: List(1,2,3).reverse).reverse

or that:

List(1,2,3) ::: List(4)

I was facing a similar issue and found that a few fields like Date were not getting a concrete value, once given the values things worked fine. Please make sure you do not have date or any other field present on the form which needs a concrete value.

This works fine for me in swift4:

func existingFile(fileName: String) -> Bool {

    let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
    let url = NSURL(fileURLWithPath: path)
    if let pathComponent = url.appendingPathComponent("\(fileName)") {
        let filePath = pathComponent.path
        let fileManager = FileManager.default
        if fileManager.fileExists(atPath: filePath) 

       {

        return true

        } else {

        return false

        }

    } else {

        return false

        }


}

You can check with this call:

   if existingFile(fileName: "yourfilename") == true {

            // your code if file exists

           } else {

           // your code if file does not exist

           }

I hope it is useful for someone. @;-]

Thanks, for your function I Used IT........................ This is my EXAMPLE

**UPDATE [RD].[PurchaseOrderHeader]
SET     [DispatchCycleNumber] ='10'
 WHERE  OrderNumber in(select * FROM XA.fn_SplitOrderIDs(@InvoiceNumberList))**


CREATE FUNCTION [XA].[fn_SplitOrderIDs]
(
    @OrderList varchar(500)
)
RETURNS 
@ParsedList table
(
    OrderID int
)
AS
BEGIN
    DECLARE @OrderID varchar(10), @Pos int

    SET @OrderList = LTRIM(RTRIM(@OrderList))+ ','
    SET @Pos = CHARINDEX(',', @OrderList, 1)

    IF REPLACE(@OrderList, ',', '') <> ''
    BEGIN
        WHILE @Pos > 0
        BEGIN
                SET @OrderID = LTRIM(RTRIM(LEFT(@OrderList, @Pos - 1)))
                IF @OrderID <> ''
                BEGIN
                        INSERT INTO @ParsedList (OrderID) 
                        VALUES (CAST(@OrderID AS int)) --Use Appropriate conversion
                END
                SET @OrderList = RIGHT(@OrderList, LEN(@OrderList) - @Pos)
                SET @Pos = CHARINDEX(',', @OrderList, 1)

        END
    END 
    RETURN
END

You can use Arrays.fill(array, -1).

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

Here's another option for those not using heatmap.2 (aheatmap is good!)

Make a sequential vector of 100 values from min to max of your input matrix, find value closest to 0 in that, make two vector of colours to and from desired midpoint, combine and use them:

breaks <- seq(from=min(range(inputMatrix)), to=max(range(inputMatrix)), length.out=100)
midpoint <- which.min(abs(breaks - 0))
rampCol1 <- colorRampPalette(c("forestgreen", "darkgreen", "black"))(midpoint)
rampCol2 <- colorRampPalette(c("black", "darkred", "red"))(100-(midpoint+1))
rampCols <- c(rampCol1,rampCol2)

(function(con) {
    var oDate = new Date();
    var nHrs = oDate.getHours();
    var nMin = oDate.getMinutes();
    var nDate = oDate.getDate();
    var nMnth = oDate.getMonth();
    var nYear = oDate.getFullYear();

    con.log(nDate + ' - ' + nMnth + ' - ' + nYear);
    con.log(nHrs + ' : ' + nMin);
})(console);

This produces an output like:

30 - 8 - 2013
21 : 30

Perhaps you may refer documentation on Date object at MDN for more information

categories_posts and categories_news start with substring 'categories_' then it is enough to check that developer_configurations_cms.cfg_name_unique starts with 'categories' instead of check if it contains the given substring. Translating all that into a query:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE 'categories%'

Simply put, to create a new local branch, do:

git branch <branch-name>

To push it to the remote repository, do:

git push -u origin <branch-name>

This might be your problem:

height: .05em;

Chrome is a bit funky with decimals, so try a fixed-pixel height:

height: 2px;

the :checked pseudo-class initially applies to such elements that have the HTML4 selected and checked attributes

Source: w3.org

So, this CSS works, although styling the color is not possible in every browser:

option:checked { color: red; }

An example of this in action, hiding the currently selected item from the drop down list.

option:checked { display:none; }

<select>_x000D_
    <option>A</option>_x000D_
    <option>B</option>_x000D_
    <option>C</option>_x000D_
</select>

To style the currently selected option in the closed dropdown as well, you could try reversing the logic:

select { color: red; }
option:not(:checked) { color: black; } /* or whatever your default style is */

Create a migration file

rails generate migration add_references_to_uploads user:references

Default foreign key name

This would create a user_id column in uploads table as a foreign key

class AddReferencesToUploads < ActiveRecord::Migration[5.2]
  def change
    add_reference :uploads, :user, foreign_key: true
  end
end

user model:

class User < ApplicationRecord
  has_many :uploads
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

Customize foreign key name:

add_reference :uploads, :author, references: :user, foreign_key: true

This would create an author_id column in the uploads tables as the foreign key.

user model:

class User < ApplicationRecord
  has_many :uploads, foreign_key: 'author_id'
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

The file needs to be decompiled (or deodex'd not sure which one). But here's another way to do it:

-Download free Tickle My Android tool on XDA: https://forum.xda-developers.com/showthread.php?t=1633333https://forum.xda-developers.com/showthread.php?t=1633333

-Copy APK into \_WorkArea1\_in\ folder
-Open "Tickle My Android.exe"
-Theming Menu
-Decompile Files->Any key to continue (ignore warning)
-Decompile Files->1->[Enter]->y[Enter]
-Wait for it to decompile in new window... Done when new window closes
-Decompiled/viewable files will be here: \_WorkArea3\_working\[App]\

1. Define interfaces for defining the capabilities. You can define multiple interfaces for multiple capabilities. These capabilities can be implemented by specific Animal or Bird.
2. Use inheritance to establish relationships among classes by sharing non-static and non-public data/methods.
3. Use Decorator_pattern to add capabilities dynamically. This will allow you to reduce number of inheritance classes & combinations.

Have a look at below example for better understanding

When to Use the Decorator Pattern?

You've almost done it. However setting flex: 0 0 <basis> declaration to the columns would prevent them from growing/shrinking; And the <basis> parameter would define the width of columns.

In addition, you could use CSS3 calc() expression to specify the height of columns with the respect to the height of the header.

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
}

#productShowcaseDetail,
#productShowcaseThumbnailContainer {
  height: calc(100% - 100px); /* excluding the height of the header */
}

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  flex: 0 0 100%; /* Let it fill the entire space horizontally */_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
  flex: 0 0 66%; /* ~ 2 * 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
  flex: 0 0 34%;  /* ~ 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: black;_x000D_
}

<div id="productShowcaseContainer">_x000D_
  <div id="productShowcaseTitle"></div>_x000D_
  <div id="productShowcaseDetail"></div>_x000D_
  <div id="productShowcaseThumbnailContainer"></div>_x000D_
</div>

(Vendor prefixes omitted due to brevity)

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div> element, it would be achieved without using calc() as follows:

<div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
</div>

#productShowcaseContainer {
  display: flex;
  flex-direction: column;
  height: 600px; width: 580px;
}

.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
.contentContainer {_x000D_
  display: flex;_x000D_
  flex: 1;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_

_x000D_
#productShowcaseDetail {_x000D_

You cannot set cookies for another domain. Allowing this would present an enormous security flaw.

You need to get b.com to set the cookie. If a.com redirect the user to b.com/setcookie.php?c=value

The setcookie script could contain the following to set the cookie and redirect to the correct page on b.com

<?php
    setcookie('a', $_GET['c']);
    header("Location: b.com/landingpage.php");
?>

You'll have to use JS to open the popup, though you can put it on the page conditionally with PHP, you're right that you'll have to use a JavaScript function.

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

Here is where you went wrong:

this.result = http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result.json());

it should be:

http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result);

or

http.get('friends.json')
                  .subscribe(result => this.result =result.json());

You have made two mistakes:

1- You assigned the observable itself to this.result. When you actually wanted to assign the list of friends to this.result. The correct way to do it is:

• you subscribe to the observable. .subscribe is the function that actually executes the observable. It takes three callback parameters as follow:

  .subscribe(success, failure, complete);

for example:

.subscribe(
    function(response) { console.log("Success Response" + response)},
    function(error) { console.log("Error happened" + error)},
    function() { console.log("the subscription is completed")}
);

Usually, you take the results from the success callback and assign it to your variable. the error callback is self explanatory. the complete callback is used to determine that you have received the last results without any errors. On your plunker, the complete callback will always be called after either the success or the error callback.

2- The second mistake, you called .json() on .map(res => res.json()), then you called it again on the success callback of the observable. .map() is a transformer that will transform the result to whatever you return (in your case .json()) before it's passed to the success callback you should called it once on either one of them.

You can also use the local commandline php-cli:

* * * * * php /local/root/path/to/tasks.php > /dev/null

It is faster and decrease load for your webserver.

If you would want to change the logging level of all the loggers use the below method. This will enumerate over all the loggers and change the logging level to given level. Please make sure that you DO NOT have log4j.appender.loggerName.Threshold=DEBUG property set in your log4j.properties file.

public static void changeLogLevel(Level level) {
    Enumeration<?> loggers = LogManager.getCurrentLoggers();
    while(loggers.hasMoreElements()) {
        Logger logger = (Logger) loggers.nextElement();
        logger.setLevel(level);
    }
}

Try this

while (true) { // loops forever until break
    try { // checks code for exceptions
        WebElement ele=
        (WebElement)wait.until(ExpectedConditions.elementToBeClickable((By.xpath(Xpath))));  
        break; // if no exceptions breaks out of loop
    } 
    catch (org.openqa.selenium.StaleElementReferenceException e1) { 
        Thread.sleep(3000); // you can set your value here maybe 2 secs
        continue; // continues to loop if exception is found
    }
}

"continue" in Java means go to end of the current loop, means: if the compiler sees continue in a loop it will go to the next iteration

Example: This is a code to print the odd numbers from 1 to 10

the compiler will ignore the print code whenever it sees continue moving into the next iteration

for (int i = 0; i < 10; i++) { 
    if (i%2 == 0) continue;    
    System.out.println(i+"");
}

Go to

Project properties >> Run >> VM options

and put this address:

-Djava.library.path="C:\opencv\build\java\x64"

The where statement gets executed before the order by. So, your desired query is saying "take the first row and then order it by t_stamp desc". And that is not what you intend.

The subquery method is the proper method for doing this in Oracle.

If you want a version that works in both servers, you can use:

select ril.*
from (select ril.*, row_number() over (order by t_stamp desc) as seqnum
      from raceway_input_labo ril
     ) ril
where seqnum = 1

The outer * will return "1" in the last column. You would need to list the columns individually to avoid this.

Copy the global variable to a variable in the scope in your controller.

function MyCtrl($scope) {
   $scope.variable1 = variable1;
}

Then you can just access it like you tried. But note that this variable will not change when you change the global variable. If you need that, you could instead use a global object and "copy" that. As it will be "copied" by reference, it will be the same object and thus changes will be applied (but remember that doing stuff outside of AngularJS will require you to do $scope.$apply anway).

But maybe it would be worthwhile if you would describe what you actually try to achieve. Because using a global variable like this is almost never a good idea and there is probably a better way to get to your intended result.

You need a back inserter to copy into vectors:

std::copy(str.c_str(), str.c_str()+str.length(), back_inserter(data));

I think these are two really different cases. In the first case memory is allocated and initialized in compile-time. In the second - in runtime.

IF EXISTS(SELECT * FROM service s WHERE s.service_id = ?)
 BEGIN
   --DO STUFF HERE

 END

Here's a solution that gives you a list of all executables and aliases. It's also portable to systems without xargs -d (e.g. Mac OS X), and properly handles paths with spaces in them.

#!/bin/bash
(echo -n $PATH | tr : '\0' | xargs -0 -n 1 ls; alias | sed 's/alias \([^=]*\)=.*/\1/') | sort -u | grep "$@"

Usage: myscript.sh [grep-options] pattern, e.g. to find all commands that begin with ls, case-insensitive, do:

myscript -i ^ls

Try:

$number = 1234545454; 
echo  $english_format_number = number_format($number, 2); 

The output will be:

1,234,545,454.00

No its not. Use Meyers CSS reset :) http://meyerweb.com/eric/tools/css/reset/

Easiest and simplest way to change date format in php

In PHP any date can be converted into the required date format using different scenarios for example to change any date format into Day, Date Month Year

$newdate = date("D, d M Y", strtotime($date));

It will show date in the following very well format

Mon, 16 Nov 2020

And if you have time as well in your existing date format for example if you have datetime format of SQL 2020-11-11 22:00:00 you can convert this into the required date format using the following

$newdateformat = date("D, d M Y H:i:s", strtotime($oldateformat));

It will show date in following well looking format

Sun, 15 Nov 2020 16:26:00

None of these answers are explicit enough to get external links to open in each platform. As per the inAppBrowser docs:

Install

cordova plugin add cordova-plugin-inappbrowser

Overwrite window.open (optional, but recommended for simplicity)

window.open = cordova.InAppBrowser.open;

If you don't overwrite window.open, you will be using the native window.open function, and can't expect to get the same results cross-platform.

Use it to open links in default browser

window.open(your_href_value, '_system');

Note that the target for the inAppBrowser (which is what the plugin name suggests it is to be used for) is '_blank', instead of '_system'.

Without the steps above, I was not able to get links to open in the default browser app cross-platform.

Extra credit

Here's an example (live) click handler for the links:

document.addEventListener('click', function (e) {
    if (e.target.tagName === 'A' &&
        e.target.href.match(/^https?:\/\//)) {
        e.preventDefault();
        window.open(e.target.href, '_system');
    }
});

If you have a SSHClient, you can also use open_sftp():

import paramiko


# lets say you have SSH client...
client = paramiko.SSHClient()

sftp = client.open_sftp()

# then you can use upload & download as shown above
...

I had a similar problem after first pulling and starting a new solution. It was fixed in visual studio by first cleaning the project. Then restoring the packages. When I built again, there were no more type or namespace errors.

Make sure you provide a number, typically a double is used. Math.Round can take 1-3 arguments, the first argument is the variable you wish to round, the second is the number of decimal places and the third is the type of rounding.

double pay = 200 + bonus;
double pay = Math.Round(pay);
// Rounds to nearest even number, rounding 0.5 will round "down" to zero because zero is even
double pay = Math.Round(pay, 2, MidpointRounding.ToEven);
// Rounds up to nearest number
double pay = Math.Round(pay, 2, MidpointRounding.AwayFromZero);

I used this:

<?php echo get_post_field('post_content', $post->ID); ?>

and this even more concise:

<?= get_post_field('post_content', $post->ID) ?>

GRANT ALL ON *.* TO 'user'@'localhost' with GRANT OPTION;

Just log in from root using the respective password if any and simply run the above command to whatever the user is.

For example:

GRANT ALL ON *.* TO 'root'@'%' with GRANT OPTION;

WifiManager wifiManager = (WifiManager)this.context.getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(status);

where status may be true or false

add permission manifest: <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

There are at least two ways to solve this.

Solution 1:

If you are okay with using an absolutely positioned element, you can use the top and bottom properties instead of height. By setting both top and bottom to 0 you force the element into taking up full height.

#menu
{
    position: absolute;
    border-right: 1px solid black;
    top: 0;
    bottom: 0;
}?

Demo

Solution 2:

Another way would be to force the HTML and BODY elements into a 100% height, to give room for a menu with 100% height:

body, html { height: 100%; }
#menu
{
    border-right: 1px solid black;
    height: 100%;
}?

Demo

At the moment you're calling ToUniversalTime() - just get rid of that:

private long ConvertToTimestamp(DateTime value)
{
    long epoch = (value.Ticks - 621355968000000000) / 10000000;
    return epoch;
}

Alternatively, and rather more readably IMO:

private static readonly DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
...

private static long ConvertToTimestamp(DateTime value)
{
    TimeSpan elapsedTime = value - Epoch;
    return (long) elapsedTime.TotalSeconds;
}

EDIT: As noted in the comments, the Kind of the DateTime you pass in isn't taken into account when you perform subtraction. You should really pass in a value with a Kind of Utc for this to work. Unfortunately, DateTime is a bit broken in this respect - see my blog post (a rant about DateTime) for more details.

You might want to use my Noda Time date/time API instead which makes everything rather clearer, IMO.

For new you should use delete. For new[] use delete[]. Your second variant is correct.

If you use Excel, then the command would be Find and MID. Here is what it would look like in Powershell.

 $text = "asdfNAME=PC123456<>Diweursejsfdjiwr"

asdfNAME=PC123456<>Diweursejsfdjiwr - Randon line of text, we want PC123456

 $text.IndexOf("E=")

7 - this is the "FIND" command for Powershell

 $text.substring(10,5)

C1234 - this is the "MID" command for Powershell

 $text.substring($text.IndexOf("E=")+2,8)

PC123456 - tada it has found and cut our text

If you are having any one or more row(s) with less or more number of columns than 2 in the dataset then this error may arise.

I am also new to Pyspark and trying to read CSV file. Following code worked for me:

In this code I am using dataset from kaggle the link is: https://www.kaggle.com/carrie1/ecommerce-data

1. Without mentioning the schema:

from pyspark.sql import SparkSession  
scSpark = SparkSession \
    .builder \
    .appName("Python Spark SQL basic example: Reading CSV file without mentioning schema") \
    .config("spark.some.config.option", "some-value") \
    .getOrCreate()

sdfData = scSpark.read.csv("data.csv", header=True, sep=",")
sdfData.show()

Now check the columns: sdfData.columns

Output will be:

['InvoiceNo', 'StockCode','Description','Quantity', 'InvoiceDate', 'CustomerID', 'Country']

Check the datatype for each column:

sdfData.schema
StructType(List(StructField(InvoiceNo,StringType,true),StructField(StockCode,StringType,true),StructField(Description,StringType,true),StructField(Quantity,StringType,true),StructField(InvoiceDate,StringType,true),StructField(UnitPrice,StringType,true),StructField(CustomerID,StringType,true),StructField(Country,StringType,true)))

This will give the data frame with all the columns with datatype as StringType

2. With schema: If you know the schema or want to change the datatype of any column in the above table then use this (let's say I am having following columns and want them in a particular data type for each of them)

from pyspark.sql import SparkSession  
from pyspark.sql.types import StructType, StructField
from pyspark.sql.types import DoubleType, IntegerType, StringType
    schema = StructType([\
        StructField("InvoiceNo", IntegerType()),\
        StructField("StockCode", StringType()), \
        StructField("Description", StringType()),\
        StructField("Quantity", IntegerType()),\
        StructField("InvoiceDate", StringType()),\
        StructField("CustomerID", DoubleType()),\
        StructField("Country", StringType())\
    ])

scSpark = SparkSession \
    .builder \
    .appName("Python Spark SQL example: Reading CSV file with schema") \
    .config("spark.some.config.option", "some-value") \
    .getOrCreate()

sdfData = scSpark.read.csv("data.csv", header=True, sep=",", schema=schema)

Now check the schema for datatype of each column:

sdfData.schema

StructType(List(StructField(InvoiceNo,IntegerType,true),StructField(StockCode,StringType,true),StructField(Description,StringType,true),StructField(Quantity,IntegerType,true),StructField(InvoiceDate,StringType,true),StructField(CustomerID,DoubleType,true),StructField(Country,StringType,true)))

Edited: We can use the following line of code as well without mentioning schema explicitly:

sdfData = scSpark.read.csv("data.csv", header=True, inferSchema = True)
sdfData.schema

The output is:

StructType(List(StructField(InvoiceNo,StringType,true),StructField(StockCode,StringType,true),StructField(Description,StringType,true),StructField(Quantity,IntegerType,true),StructField(InvoiceDate,StringType,true),StructField(UnitPrice,DoubleType,true),StructField(CustomerID,IntegerType,true),StructField(Country,StringType,true)))

The output will look like this:

sdfData.show()

You want to reshape the array.

B = np.reshape(A, (-1, 2))

where -1 infers the size of the new dimension from the size of the input array.

int to hex:

int a = 72;

Console.WriteLine("{0:X}", a);

hex to int:

int b = 0xB76;

Console.WriteLine(b);

F# is essentially the C++ of functional programming languages. They kept almost everything from Objective Caml, including the really stupid parts, and threw it on top of the .NET runtime in such a way that it brings in all the bad things from .NET as well.

For example, with Objective Caml you get one type of null, the option<T>. With F# you get three types of null, option<T>, Nullable<T>, and reference nulls. This means if you have an option you need to first check to see if it is "None", then you need to check if it is "Some(null)".

F# is like the old Java clone J#, just a bastardized language just to attract attention. Some people will love it, a few of those will even use it, but in the end it is still a 20-year-old language tacked onto the CLR.

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.

You can read up this property every few calls, Environment.StackTrace , and if the stacktrace exceded a specific threshold that you preset, you can return the function.

You should also try to replace some recursive functions with loops.

A lot of people, including me, use sqlfiddle.com to test SQL.

I put my customized changes in the User package:

*nix: ~/.config/sublime-text-2/Packages/User/Scala.tmLanguage
*Windows: %APPDATA%\Sublime Text 2\Packages\User\Scala.tmLanguage

Which also means it's in JSON format:

{
  "extensions":
  [
    "sbt"
  ]
}

This is the same place the

View -> Syntax -> Open all with current extension as ...

menu item adds it (creating the file if it doesn't exist).

In Ubuntu 10.04 (Lucid), I could successfully pip install scipy (within a virtualenv) after installing some of its dependencies, in particular:

$ sudo apt-get install libamd2.2.0 libblas3gf libc6 libgcc1 libgfortran3 liblapack3gf libumfpack5.4.0 libstdc++6 build-essential gfortran libatlas-sse2-dev python-all-dev

Besides what @khmarbaise has pointed out, I think you have mistyped your JAVA_HOME. If you have installed in the default location, then there should be no "-" (hyphen) between jdk and 1.7.0_04. So it would be

JAVA_HOME C:\Program Files\Java\jdk1.7.0_04 

As answer by Neodan mongoexport is quite useful with -q option for query. It also convert ObjectId to standard format of JSON "$oid". E.g:

mongoexport -d yourdb -c yourcol --jsonArray --pretty -q '{"field": "filter value"}' -o output.json

Another method through re module. It does the reverse operation of matching all the words instead of spitting the whole sentence by space.

>>> import re
>>> s = "many   fancy word \nhello    \thi"
>>> re.findall(r'\S+', s)
['many', 'fancy', 'word', 'hello', 'hi']

Above regex would match one or more non-space characters.

A good example of this casting is using *= or /=

byte b = 10;
b *= 5.7;
System.out.println(b); // prints 57

or

byte b = 100;
b /= 2.5;
System.out.println(b); // prints 40

or

char ch = '0';
ch *= 1.1;
System.out.println(ch); // prints '4'

or

char ch = 'A';
ch *= 1.5;
System.out.println(ch); // prints 'a'

You can use eval() method to declare dynamic variables. But better to use an Array.

for (var i = 0; i < coords.length; ++i) {
    var str ="marker"+ i+" = undefined";
    eval(str);
}

I would suggest you to don't modify web.config from your, because every time when change, it will restart your application.

However you can read web.config using System.Configuration.ConfigurationManager.AppSettings

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

• 0.5.0
• 0.5.9
• 0.6.0

For clarification, each pair is equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

I see the other one is closed. So basically here's the rough of my code. I think you are missing the string cmd comment. For example if my store procedure is call:DBO.Test. I would need to write cmd="DBO.test". Then do command type equal to store procedure, and blah blah blah

Connection.open();
String cmd="DBO.test"; //the command
Sqlcommand mycommand;

On macOS 10.12.x (Sierra), if you have spaces in file names or subdirectories, you can use the following:

find . -name '*.swift' -exec echo '"{}"' \; |xargs wc -l

In case your using testing.M and associated setup/teardown; -v is valid here as well.

package g 

import (
    "os"
    "fmt"
    "testing"
)

func TestSomething(t *testing.T) {
    t.Skip("later")
}

func setup() {
    fmt.Println("setting up")
}

func teardown() {
    fmt.Println("tearing down")
}

func TestMain(m *testing.M) {
    setup()
    result := m.Run()
    teardown()
    os.Exit(result)
}

$ go test -v g_test.go 
setting up
=== RUN   TestSomething
    g_test.go:10: later
--- SKIP: TestSomething (0.00s)
PASS

Okay, how about a CSS answer! We use display: table. Then each of the divs are rows, and finally we apply height of 100% to middle 'row' and voilà.

http://jsfiddle.net/NfmX3/3/

body { display: table; }
div { display: table-row; }
#content {
    width:450px; 
    margin:0 auto;
    text-align: center;
    background-color: blue;
    color: white;
    height: 100%;
}

verse = "If you can keep your head when all about you\n Are losing theirs and blaming it on you,\nIf you can trust yourself when all men doubt you,\n But make allowance for their doubting too;\nIf you can wait and not be tired by waiting,\n Or being lied about, don’t deal in lies,\nOr being hated, don’t give way to hating,\n And yet don’t look too good, nor talk too wise:"

enter code here

print(verse)
#1. What is the length of the string variable verse?
verse_length = len(verse)
print("The length of verse is: {}".format(verse_length))
#2. What is the index of the first occurrence of the word 'and' in verse?
index = verse.find("and")
print("The index of the word 'and' in verse is {}".format(index))

There is a circumstance where you're required to declare it final --otherwise it will result in compile error--, namely passing them through into anonymous classes. Basic example:

public FileFilter createFileExtensionFilter(final String extension) {
    FileFilter fileFilter = new FileFilter() {
        public boolean accept(File pathname) {
            return pathname.getName().endsWith(extension);
        }
    };

    // What would happen when it's allowed to change extension here?
    // extension = "foo";

    return fileFilter;
}

Removing the final modifier would result in compile error, because it isn't guaranteed anymore that the value is a runtime constant. Changing the value from outside the anonymous class would namely cause the anonymous class instance to behave different after the moment of creation.

lines=[]
with open('file') as file:
   lines.append(file.readline())

An emulator is a model of a system which will accept any valid input that that the emulated system would accept, and produce the same output or result. So your software is an emulator, only if it reproduces the behavior of the emulated system precisely.

With the Material Components Library you can use the com.google.android.material.textfield.TextInputLayout.

You can apply a custom style to change the colors.

To change the hint color you have to use these attributes:
hintTextColor and android:textColorHint.

<style name="Custom_textinputlayout_filledbox" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox">
    <!-- The color of the label when it is collapsed and the text field is active -->
    <item name="hintTextColor">?attr/colorPrimary</item>

    <!-- The color of the label in all other text field states (such as resting and disabled) -->
    <item name="android:textColorHint">@color/selector_hint_text_color</item>
</style>

You should use a selector for the android:textColorHint. Something like:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:alpha="0.38" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
  <item android:alpha="0.6" android:color="?attr/colorOnSurface"/>
</selector>

To change the bottom line color you have to use the attribute: boxStrokeColor.

<style name="Custom_textinputlayout_filledbox" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox">
    ....
    <item name="boxStrokeColor">@color/selector_stroke_color</item>
</style>

Also in this case you should use a selector. Something like:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:color="?attr/colorPrimary" android:state_focused="true"/>
  <item android:alpha="0.87" android:color="?attr/colorOnSurface" android:state_hovered="true"/>
  <item android:alpha="0.12" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
  <item android:alpha="0.38" android:color="?attr/colorOnSurface"/>
</selector>

You can also apply these attributes in your layout:

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox"
    app:boxStrokeColor="@color/selector_stroke_color"
    app:hintTextColor="?attr/colorPrimary"
    android:textColorHint="@color/selector_hint_text_color"
    ...>

Use the default version:

Collections.sort(myarrayList);

Of course this requires that your Elements implement Comparable, but the same holds true for the version you mentioned.

BTW: you should use generics in your code, that way you get compile-time errors if your class doesn't implement Comparable. And compile-time errors are much better than the runtime errors you'll get otherwise.

List<MyClass> list = new ArrayList<MyClass>();
// now fill up the list

// compile error here unless MyClass implements Comparable
Collections.sort(list); 

UPDATED since this was last downvoted....

I only saw the portion

var dots = 5
function increase(){
    dots = dots+5;
}

before, but it was later shown to me that the txt box feeds the variable dots. Because of this, you will need to be sure to "cleanse" the input, to be sure it only has integers, and not malicious code.

One easy way to do this is to parse the textbox with an onkeyup() event to ensure it has numeric characters:

<input size="40" id="txt" value="Write a character here!" onkeyup="GetChar (event);"/>

where the event would give an error and clear the last character if the value is not a number:

<script type="text/javascript">
    function GetChar (event){
        var keyCode = ('which' in event) ? event.which : event.keyCode;
        var yourChar = String.fromCharCode();
        if (yourChar != "0" &&
            yourChar != "1" &&
            yourChar != "2" &&
            yourChar != "3" && 
            yourChar != "4" &&
            yourChar != "5" &&
            yourChar != "6" && 
            yourChar != "7" &&
            yourChar != "8" && 
            yourChar != "9")
        {
            alert ('The character was not a number');
            var source = event.target || event.srcElement;
            source.value = source.value.substring(0,source.value-2);
        }
    }
</script>

Obviously you could do that with regex, too, but I took the lazy way out.

Since then you would know that only numbers could be in the box, you should be able to just use eval():

dots = eval(dots) + 5;

From memory, you call stringstream::str() to get the std::string value out.

public class Class1 {
private String extref="MY";

public String getExtref() {
    return extref;
}

public String setExtref(String extref) {
    return this.extref = extref;
}

public static void main(String[] args) {

    Class1 obj=new Class1();
    String value=obj.setExtref("AFF");
    int returnedValue=getMethod(value);     
    System.out.println(returnedValue);
}

/**
 * @param value
 * @return
 */
private static int getMethod(String value) {
      HashMap<Integer, String> hashmap1 = new HashMap<Integer, String>();
        hashmap1.put(1,"MY");
        hashmap1.put(2,"AFF");

        if (hashmap1.containsValue(value))
        {
            for (Map.Entry<Integer,String> e : hashmap1.entrySet()) {
                Integer key = e.getKey();
                Object value2 = e.getValue();
                if ((value2.toString()).equalsIgnoreCase(value))
                {
                    return key;
                }
            }
        }   
        return 0;

}
}

I hope this doesn't count as spam. I humbly ended up writing a function after endless debug sessions: http://github.com/halilim/Javascript-Simple-Object-Inspect

function simpleObjInspect(oObj, key, tabLvl)
{
    key = key || "";
    tabLvl = tabLvl || 1;
    var tabs = "";
    for(var i = 1; i < tabLvl; i++){
        tabs += "\t";
