Here are a few ways of removing a single ' from a string in python.

• str.replace

  replace is usually used to return a string with all the instances of the substring replaced.

  "A single ' char".replace("'","")
  

• str.translate

  In Python 2

  To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.

  "A single ' char".translate(None,"'")
  

  In Python 3

  You will have to use str.maketrans

  "A single ' char".translate(str.maketrans({"'":None}))
  

• re.sub

  Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.

  re.sub("'","","A single ' char")
  

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

• Using list comprehension

  ''.join([c for c in string if c != "'"])
  

• Using generator Expression

  ''.join(c for c in string if c != "'")
  

Another final method can be used also (Again not recommended - works only if there is only one occurrence )

• Using list call along with remove and join.

  x = list(string)
  x.remove("'")
  ''.join(x)
  

<div class="prev">Prev</div>

<div class="next">Next</div>

$('.your_class').slick({
        infinite: true,
        speed: 300,
        slidesToShow: 5,
        slidesToScroll: 5,
        arrows: true,
        prevArrow: $('.prev'),
        nextArrow: $('.next')
});

If you actually want to filter blank lines from a file then you may try this:

(gc $source_file).Trim() | ? {$_.Length -gt 0}

This error message can happen if you have duplicate entries/entities and run SaveChanges().

You can control select all customised classes and methods, and right-click, choose "Source", then select "Generate Element Comment". You should get what you want.

If you want to modify the Code Template then you can go to Preferences -- Java -- Code Style -- Code Templates, then do whatever you want.

This happens because you use the savedValue in the onCreate() method. The savedValue is updated in onRestoreInstanceState() method, but onRestoreInstanceState() is called after the onCreate() method. You can either:

1. Update the savedValue in onCreate() method, or
2. Move the code that use the new savedValue in onRestoreInstanceState() method.
   

But I suggest you to use the first approach, making the code like this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int display_mode = getResources().getConfiguration().orientation;

    if (display_mode == 1) {

        setContentView(R.layout.main_grid);
        mGrid = (GridView) findViewById(R.id.gridview);
        mGrid.setColumnWidth(95);
        mGrid.setVisibility(0x00000000);
        // mGrid.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

    } else {
        setContentView(R.layout.main_grid_land);
        mGrid = (GridView) findViewById(R.id.gridview);
        mGrid.setColumnWidth(95);
        Log.d("Mode", "land");
        // mGrid.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

    }
    if (savedInstanceState != null) {
        savedUser = savedInstanceState.getString("TEXT");
    } else {
        savedUser = ""
    }
    Log.d("savedUser", savedUser);
    if (savedUser.equals("admin")) { //value 0
        adapter.setApps(appManager.getApplications());
    } else if (savedUser.equals("prof")) { //value 1
        adapter.setApps(appManager.getTeacherApplications());
    } else {// default value
        appManager = new ApplicationManager(this, getPackageManager());
        appManager.loadApplications(true);
        bindApplications();
    }
}

In some projects it really doesn't make sense to have the detailed timezones of Africa, Europe or Pacific. So here is a short version

$timezoneTable = array(
    "-12" => "(GMT -12:00) Eniwetok, Kwajalein",
    "-11" => "(GMT -11:00) Midway Island, Samoa",
    "-10" => "(GMT -10:00) Hawaii",
    "-9" => "(GMT -9:00) Alaska",
    "-8" => "(GMT -8:00) Pacific Time (US & Canada)",
    "-7" => "(GMT -7:00) Mountain Time (US & Canada)",
    "-6" => "(GMT -6:00) Central Time (US & Canada), Mexico City",
    "-5" => "(GMT -5:00) Eastern Time (US & Canada), Bogota, Lima",
    "-4" => "(GMT -4:00) Atlantic Time (Canada), Caracas, La Paz",
    "-3.5" => "(GMT -3:30) Newfoundland",
    "-3" => "(GMT -3:00) Brazil, Buenos Aires, Georgetown",
    "-2" => "(GMT -2:00) Mid-Atlantic",
    "-1" => "(GMT -1:00) Azores, Cape Verde Islands",
    "0" => "(GMT) Western Europe Time, London, Lisbon, Casablanca",
    "1" => "(GMT +1:00) Brussels, Copenhagen, Madrid, Paris",
    "2" => "(GMT +2:00) Kaliningrad, South Africa",
    "3" => "(GMT +3:00) Baghdad, Riyadh, Moscow, St. Petersburg",
    "3.5" => "(GMT +3:30) Tehran",
    "4" => "(GMT +4:00) Abu Dhabi, Muscat, Baku, Tbilisi",
    "4.5" => "(GMT +4:30) Kabul",
    "5" => "(GMT +5:00) Ekaterinburg, Islamabad, Karachi, Tashkent",
    "5.5" => "(GMT +5:30) Bombay, Calcutta, Madras, New Delhi",
    "6" => "(GMT +6:00) Almaty, Dhaka, Colombo",
    "7" => "(GMT +7:00) Bangkok, Hanoi, Jakarta",
    "8" => "(GMT +8:00) Beijing, Perth, Singapore, Hong Kong",
    "9" => "(GMT +9:00) Tokyo, Seoul, Osaka, Sapporo, Yakutsk",
    "9.5" => "(GMT +9:30) Adelaide, Darwin",
    "10" => "(GMT +10:00) Eastern Australia, Guam, Vladivostok",
    "11" => "(GMT +11:00) Magadan, Solomon Islands, New Caledonia",
    "12" => "(GMT +12:00) Auckland, Wellington, Fiji, Kamchatka"
);

echo "<select>";
foreach ($timezoneTable as $k => $v){
    $sel = ($k==-5)?" selected":"";
    echo "<option value='".$k."'".$sel.">".$v."</option>";
}
echo "</select>" 

this will generate a select as below:

dat <- dat[-1, ] worked but it killed my dataframe, changing it into another type. Had to instead use dat <- data.frame(dat[-1, ]) but this is possibly a special case as this dataframe initially had only one column.

Works perfectly with python 3.5+

client:

import requests
data = {'sender':   'Alice',
    'receiver': 'Bob',
    'message':  'We did it!'}
r = requests.post("http://localhost:8080", json={'json_payload': data})

server:

class Root(object):

    def __init__(self, content):
        self.content = content
        print self.content  # this works

    exposed = True

    def GET(self):
        cherrypy.response.headers['Content-Type'] = 'application/json'
        return simplejson.dumps(self.content)

    @cherrypy.tools.json_in()
    @cherrypy.tools.json_out()
    def POST(self):
        self.content = cherrypy.request.json
        return {'status': 'success', 'message': 'updated'}

An XSD file is an XML Schema Definition and it is used to provide a standard method of checking that a given XML document conforms to what you expect.

https://developers.google.com/web/tools/chrome-devtools/network-performance/understanding-resource-timing

This comes from the official site of Chome-devtools and it helps. Here i quote:

• Queuing If a request is queued it indicated that:
  • The request was postponed by the rendering engine because it's considered lower priority than critical resources (such as scripts/styles). This often happens with images.
  • The request was put on hold to wait for an unavailable TCP socket that's about to free up.
  • The request was put on hold because the browser only allows six TCP connections per origin on HTTP 1. Time spent making disk cache entries (typically very quick.)
• Stalled/Blocking Time the request spent waiting before it could be sent. It can be waiting for any of the reasons described for Queueing. Additionally, this time is inclusive of any time spent in proxy negotiation.

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

Have you gone through google's geocoding api. The following link shall help you get started: http://code.google.com/apis/maps/documentation/geocoding/#GeocodingRequests

This is my solution for my scenario:

<div class="btn-group btn-group-justified">
    <a class="btn btn-default" ng-class="{'btn-success': hover.left, 'btn-danger': hover.right}" ng-click="setMatch(-1)" role="button" ng-mouseenter="hover.left = true;" ng-mouseleave="hover.left = false;">
        <i class="fa fa-thumbs-o-up fa-5x pull-left" ng-class="{'fa-rotate-90': !hover.left && !hover.right, 'fa-flip-vertical': hover.right}"></i>
        {{ song.name }}
    </a>
    <a class="btn btn-default" ng-class="{'btn-success': hover.right, 'btn-danger': hover.left}" ng-click="setMatch(1)" role="button" ng-mouseenter="hover.right = true;" ng-mouseleave="hover.right = false;">
        <i class="fa fa-thumbs-o-up fa-5x pull-right" ng-class="{'fa-rotate-270': !hover.left && !hover.right, 'fa-flip-vertical': hover.left}"></i>
        {{ match.name }}
    </a>
</div>

default state:

on hover:

zeros=[0]*4

you can replace 4 in the above example with whatever number you want.

GOOGLEFINANCE can have a 20 minutes delay, so refreshing every minute would not really help.

Instead of GOOGLEFINANCE you can use different source. I'm using this RealTime stock prices(I tried a couple but this is the easiest by-far to implement. They have API that retuen JSON { Name: CurrentPrice }

Here's a little script you can use in Google Sheets(Tools->Script Editor)

function GetStocksPrice() {      
   var url = 'https://financialmodelingprep.com/api/v3/stock/real-time- 
   price/AVP,BAC,CHK,CY,GE,GPRO,HIMX,IMGN,MFG,NIO,NMR,SSSS,UCTT,UMC,ZNGA';
   var response = UrlFetchApp.fetch(url);

   // convert json string to json object
   var jsonSignal = JSON.parse(response);    

  // define an array of all the object keys
  var headerRow = Object.keys(jsonSignal);
  // define an array of all the object values
  var values = headerRow.map(function(key){ return jsonSignal[key]});   
  var data = values[0];

  // get sheet by ID -  
  // you can get the sheet unqiue ID from the your current sheet url
  var jsonSheet = SpreadsheetApp.openById("Your Sheet UniqueID");  
  //var name = jsonSheet.getName();

  var sheet = jsonSheet.getSheetByName('Sheet1'); 

  // the column to put the data in -> Y
  var letter = "F";

  // start from line 
  var index = 4;
  data.forEach(function( row, index2 ) { 

     var keys = Object.keys(row);
     var value2 = row[keys[1]];            

     // set value loction
     var cellXY = letter +  index;      
     sheet.getRange(cellXY).setValue(value2);  
  
     index = index + 1;    
 });  
}

Now you need to add a trigger that will execute every minute.

1. Go to Project Triggers -> click on the Watch icon next to the Save icon
2. Add Trigger
3. In -> Choose which function to run -> GetStocksPrice
4. In -> Select event source -> Time-driven
5. In -> Select type of time based trigger -> Minutes timer
6. In -> Select minute interval -> Every minute

And your set :)

I have done it by the following way

1. Start cmd
2. Go to the "C:\Program Files\MySQL\MySQL Server 5.6\bin"
3. type mysqld --install

Build a hybrid app. Anyways Java is not enough for a software engineer , you need to learn JS,HTML5,CSS as well for becoming a full stack mobile/app developer. Build the complete backend using Java & frontend using Cordova/Phonegap.

I'm assuming you dont need the last drop of juice from the hardware even hybind app should suffice your needs.

Build a responsive webapp using Bootstrap 4 + React JS. Use https://github.com/ipselon/structor to quickly build up the frontend. Now the web app becomes an app in the browser.

You could also take the same app and build it using cordova to publish a app on ios/android platform.

You simply need to remove v-bind (:) from selected and required attributes. Like this :-

<template>_x000D_
    <select class="form-control" v-model="selected" required @change="changeLocation">_x000D_
        <option selected>Choose Province</option>_x000D_
        <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>_x000D_
    </select>_x000D_
</template>

You are not binding anything to the vue instance through these attributes thats why it is giving error.

I have a way to do it very simply, and I'd like to share it.

When I want to square mi TextViews, I just put them in a LinearLayout. I set the background color of my LinearLayout, and I add a margin to my TextView. The result is exactly as if you square the TextView.

It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!

The only times you should need to escape are when trying to put " inside a string, or ' in a character:

String quotes = "He said \"Hello, World!\"";
char quote = '\'';

Install Nginx Extras

The string created by calling Hash#inspect can be turned back into a hash by calling eval on it. However, this requires the same to be true of all of the objects in the hash.

If I start with the hash {:a => Object.new}, then its string representation is "{:a=>#<Object:0x7f66b65cf4d0>}", and I can't use eval to turn it back into a hash because #<Object:0x7f66b65cf4d0> isn't valid Ruby syntax.

However, if all that's in the hash is strings, symbols, numbers, and arrays, it should work, because those have string representations that are valid Ruby syntax.

Very Simply Short week day name with Month and year

output

Tue, 16-Feb

I would recommend you using the Conditional Attribute!

Update: 3.5 years later

You can use #if like this (example copied from MSDN):

// preprocessor_if.cs
#define DEBUG
#define VC_V7
using System;
public class MyClass 
{
    static void Main() 
    {
#if (DEBUG && !VC_V7)
        Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V7)
        Console.WriteLine("VC_V7 is defined");
#elif (DEBUG && VC_V7)
        Console.WriteLine("DEBUG and VC_V7 are defined");
#else
        Console.WriteLine("DEBUG and VC_V7 are not defined");
#endif
    }
}

Only useful for excluding parts of methods.

If you use #if to exclude some method from compilation then you will have to exclude from compilation all pieces of code which call that method as well (sometimes you may load some classes at runtime and you cannot find the caller with "Find all references"). Otherwise there will be errors.

If you use conditional compilation on the other hand you can still leave all pieces of code that call the method. All parameters will still be validated by the compiler. The method just won't be called at runtime. I think that it is way better to hide the method just once and not have to remove all the code that calls it as well. You are not allowed to use the conditional attribute on methods which return value - only on void methods. But I don't think this is a big limitation because if you use #if with a method that returns a value you have to hide all pieces of code that call it too.

Here is an example:

    // calling Class1.ConditionalMethod() will be ignored at runtime 
    // unless the DEBUG constant is defined


    using System.Diagnostics;
    class Class1 
    {
       [Conditional("DEBUG")]
       public static void ConditionalMethod() {
          Console.WriteLine("Executed Class1.ConditionalMethod");
       }
    }

Summary:

I would use #ifdef in C++ but with C#/VB I would use Conditional attribute. This way you hide the method definition without having to hide the pieces of code that call it. The calling code is still compiled and validated by the compiler, the method is not called at runtime though. You may want to use #if to avoid dependencies because with Conditional attribute your code is still compiled.

Here's what I used in a system that didn't have "strings" command installed

cat yourfilename | tr -cd "[:print:]"

This prints the text and removes unprintable characters in one fell swoop, unlike "cat -v filename" which requires some postprocessing to remove unwanted stuff. Note that some of the binary data may be printable so you'll still get some gibberish between the good stuff. I think strings removes this gibberish too if you can use that.

Unlike the C#/.NET class library (and most other sensible languages), when you pass a String in as the string-to-match argument to the string.replace method, it doesn't do a string replace. It converts the string to a RegExp and does a regex substitution. As Gumbo explains, a regex substitution requires the g?lobal flag, which is not on by default, to replace all matches in one go.

If you want a real string-based replace — for example because the match-string is dynamic and might contain characters that have a special meaning in regexen — the JavaScript idiom for that is:

var id= 'c_'+date.split('/').join('');

I open files "directly" from WinSCP which opens the files in Notepad++ I had a php files on my linux server which always opened in Mac format no matter what I did :-(

If I downloaded the file and then opened it from local (windows) it was open as Dos/Windows....hmmm

The solution was to EOL-convert the local file to "UNIX/OSX Format", save it and then upload it.

Now when I open the file directly from the server it's open as "Dos/Windows" :-)

Updated Answer for Node.js ~>0.8

Node is able to concatenate buffers on its own now.

var newBuffer = Buffer.concat([buffer1, buffer2]);

Old Answer for Node.js ~0.6

I use a module to add a .concat function, among others:

https://github.com/coolaj86/node-bufferjs

I know it isn't a "pure" solution, but it works very well for my purposes.

For bootstrap 4 just add this class:

Not a for each exactly, but you can do nested SQL

    distinct a.ID, 
    a.col2, 
    (SELECT 
        SUM(b.size) 
    FROM 
        tableb b 
    WHERE 
        b.id = a.col3)
FROM
    tablea a

I got the same issue when adding @angular/flex-layout to my Angular 8 project now with

`npm install @angular/flex-layout --save`.

This since now that command installed the major 9th version of the flex-layout package. Instead of upgrading everything else to the last version, I solved it by installing the last 8th major version of the package instead.

 npm install @angular/[email protected] --save

C++ (and C for that matter) split the "declaration" and the "implementation" of types, functions and classes. You should "declare" the classes you need in a header-file (.h or .hpp), and put the corresponding implementation in a .cpp-file. Then, when you wish to use (access) a class somewhere, you #include the corresponding headerfile.

Example

ClassOne.hpp:

class ClassOne
{
public:
  ClassOne(); // note, no function body        
  int method(); // no body here either
private:
  int member;
};

ClassOne.cpp:

#include "ClassOne.hpp"

// implementation of constructor
ClassOne::ClassOne()
 :member(0)
{}

// implementation of "method"
int ClassOne::method()
{
  return member++;
}

main.cpp:

#include "ClassOne.hpp" // Bring the ClassOne declaration into "view" of the compiler

int main(int argc, char* argv[])
{
  ClassOne c1;
  c1.method();

  return 0;
}

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.

Easily hit CTRL+SHIFT+T . This will look in the files' names.

You can use a InputFilter, that's the way:

EditText myEditText = (EditText) findViewById(R.id.editText1);
InputFilter[] filters = new InputFilter[1];
filters[0] = new InputFilter.LengthFilter(10); //Filter to 10 characters
myEditText .setFilters(filters);

download jstz.min.js and add a function to your html page

<script language="javascript">
    function getTimezoneName() {
        timezone = jstz.determine()
        return timezone.name();
    }
</script>

and call this function from your display tag

Your problem is that the indices returned by match.start() correspond to the position of the character as it appeared in the original string when you matched it; however, as you rewrite the string c every time, these indices become incorrect.

The best approach to solve this is to use replaceAll, for example:

        System.out.println(c.replaceAll("[^a-zA-Z0-9]", ""));

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

I believe it would be:

void setCurrent(boolean current)
boolean isCurrent()

I think your code is right. If you run the following code it converts the string '60' which is treated as varchar and it returns integer 60, if there is integer containing string in second it works.

select CONVERT(bigint,'60') as seconds 

and it returns

60

--setup
IF OBJECT_ID('tempdb..#T') IS NOT NULL DROP TABLE #T;
CREATE TABLE #T(ID INT NOT NULL IDENTITY(1,1) PRIMARY KEY, NAME VARCHAR(10))
INSERT INTO #T (Name) VALUES('JOHN'),(''),(NULL);
SELECT * FROM #T
 1  JOHN
 2  -- is empty string
 3  NULL

You can examine '' as NULL by converting it to NULL using NULLIF

--here you set '' to null
UPDATE #T SET NAME = NULLIF(NAME,'')
SELECT * FROM #T 
 1  JOHN
 2  NULL
 3  NULL

or you can examine NULL as '' using SELECT ISNULL(NULL,'')

-- here you set NULL to ''
UPDATE #T SET NAME = ISNULL(NULL,'') WHERE NAME IS NULL
SELECT * FROM #T
1   JOHN
2   -- is empty string
3   -- is empty string

--clean up
DROP TABLE #T

For COM/ActiveX references, VS 2012 will show this error right on using statement. Which is quite funny, since it's saying that may be you are missing a using statement.

To solve this: register the actual COM/ActiveX dll even if it's in the neighbor project, and add a reference through COM channel, not project channel. It will add Interop.ProjectName instead of ProjectName as a reference and this solves this strange bug.

Remove NodeJs and npm in your system and reinstall it by following commands

Uninlstallation

sudo apt remove nodejs
sudo apt remove npm

Fresh Installation

sudo apt install nodejs
sudo apt install npm

Configuration optional, in some cases users may face permission errors.

1. user defined directory where npm will install packages

   mkdir ~/.npm-global

2. configure npm

   npm config set prefix '~/.npm-global'

3. add directory to path

   echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.profile

4. refresh path for the current session

   source ~/.profile

5. cross-check npm and node modules installed successfully in our system

   node -v
npm -v

Installation of npx

sudo npm i -g npx
npx -v

Well-done we are ready to go... now you can easily use npx anywhere in your system.

What is unit testing?

Unit testing simply verifies that individual units of code (mostly functions) work as expected. Usually you write the test cases yourself, but some can be automatically generated.

The output from a test can be as simple as a console output, to a "green light" in a GUI such as NUnit, or a different language-specific framework.

Performing unit tests is designed to be simple, generally the tests are written in the form of functions that will determine whether a returned value equals the value you were expecting when you wrote the function (or the value you will expect when you eventually write it - this is called Test Driven Development when you write the tests first).

How do you perform unit tests?

Imagine a very simple function that you would like to test:

int CombineNumbers(int a, int b) {
    return a+b;
}

The unit test code would look something like this:

void TestCombineNumbers() {
    Assert.IsEqual(CombineNumbers(5, 10), 15); // Assert is an object that is part of your test framework
    Assert.IsEqual(CombineNumbers(1000, -100), 900);
}

When you run the tests, you will be informed that these tests have passed. Now that you've built and run the tests, you know that this particular function, or unit, will perform as you expect.

Now imagine another developer comes along and changes the CombineNumbers() function for performance, or some other reason:

int CombineNumbers(int a, int b) {
    return a * b;
}

When the developer runs the tests that you have created for this very simple function, they will see that the first Assert fails, and they now know that the build is broken.

When should you perform unit tests?

They should be done as often as possible. When you are performing tests as part of the development process, your code is automatically going to be designed better than if you just wrote the functions and then moved on. Also, concepts such as Dependency Injection are going to evolve naturally into your code.

The most obvious benefit is knowing down the road that when a change is made, no other individual units of code were affected by it if they all pass the tests.

Just in case somebody else gets in the same situation like me yesterday (2016-06-22) and also does not succeed with the already posted approaches - on Lubuntu 14.04 it worked for me using the following chain of commands:

cd googletest
cmake -DBUILD_SHARED_LIBS=ON .
make
cd googlemock
sudo cp ./libgmock_main.so ./gtest/libgtest.so gtest/libgtest_main.so ./libgmock.so /usr/lib/
sudo ldconfig

1 line without list comprehensions.

>>> any(map(lambda each: each in [2,3,4], [1,2]))
True
>>> any(map(lambda each: each in [2,3,4], [1,5]))
False

After some searching I found this on a Google groups discussion:

docker currently inhibits this capability for enhanced safety.

That is because the ulimit settings of the host system apply to the docker container. It is regarded as a security risk that programs running in a container can change the ulimit settings for the host.

The good news is that you have two different solutions to choose from.

1. Remove sys_resource from lxc_template.go and recompile docker. Then you'll be able to set the ulimit as high as you like.

or

2. Stop the docker demon. Change the ulimit settings on the host. Start the docker demon. It now has your revised limits, and its child processes as well.

I applied the second method:

1. sudo service docker stop;

2. changed the limits in /etc/security/limits.conf

3. reboot the machine

4. run my container

5. run ulimit -a in the container to confirm the open files limit has been inherited.

If your rootViewController is UINavigationViewController, which was set up in AppDelegate class, then

    + (UIViewController *) getNearestViewController:(Class) c {
NSArray *arrVc = [[[[UIApplication sharedApplication] keyWindow] rootViewController] childViewControllers];

for (UIViewController *v in arrVc)
{
    if ([v isKindOfClass:c])
    {
        return v;
    }
}

return nil;}

Where c required view controllers class.

USAGE:

     RequiredViewController* rvc = [Utilities getNearestViewController:[RequiredViewController class]];

Take a look at http://jsfiddle.net/TroyAlford/ZZEk8/ for a working example of the below:

<img id='myImg' src='/my/img/link.gif' />

<script type="text/javascript">
    $(document).bind('click', function () {
        // Add a click-handler to the image.
        $('#myImg').bind('click', function (ev) {
            var $img = $(ev.target);

            var offset = $img.offset();
            var x = ev.clientX - offset.left;
            var y = ev.clientY - offset.top;

            alert('clicked at x: ' + x + ', y: ' + y);
        });
    });
</script>

Note that the above will get you the x and the y relative to the image's box - but will not correctly take into account margin, border and padding. These elements aren't actually part of the image, in your case - but they might be part of the element that you would want to take into account.

In this case, you should also use $div.outerWidth(true) - $div.width() and $div.outerHeight(true) - $div.height() to calculate the amount of margin / border / etc.

Your new code might look more like:

<img id='myImg' src='/my/img/link.gif' />

<script type="text/javascript">
    $(document).bind('click', function () {
        // Add a click-handler to the image.
        $('#myImg').bind('click', function (ev) {
            var $img = $(ev.target);

            var offset = $img.offset(); // Offset from the corner of the page.
            var xMargin = ($img.outerWidth() - $img.width()) / 2;
            var yMargin = ($img.outerHeight() - $img.height()) / 2;
            // Note that the above calculations assume your left margin is 
            // equal to your right margin, top to bottom, etc. and the same 
            // for borders.

            var x = (ev.clientX + xMargin) - offset.left;
            var y = (ev.clientY + yMargin) - offset.top;

            alert('clicked at x: ' + x + ', y: ' + y);
        });
    });
</script>

In case the Jenkins is triggering a build by restricting it to run on a slave or any other server (you may find it in the below setting under 'configure')

then the Path to Git executable should be set as per the 'slave_server_hostname' or any other server where the git commands are executed.

Abstract your initialization into a method, and call the method from mounted and wherever else you want.

new Vue({
  methods:{
    init(){
      //call API
      //Setup game
    }
  },
  mounted(){
    this.init()
  }
})

Then possibly have a button in your template to start over.

<button v-if="playerWon" @click="init">Play Again</button>

In this button, playerWon represents a boolean value in your data that you would set when the player wins the game so the button appears. You would set it back to false in init.

If you are using a mac, you can get the UUID out of the "System Report" available from "About this Mac." With the device attached, open the USB section and click on iPhone. The UUID appears under "Serial Number"

There is some confusion when using pip install in Windows. The instructions talk about a specific folder which has youtube-dl.exe. There is no such folder if you use pip install.

The solution is to:

• Download one of the builds from https://ffmpeg.zeranoe.com/
• Extract the zip contents
• Place the contents of the bin folder (there are three exe files) in any folder which is a path in Windows. I personally use Ananconda, so I placed them in /Anaconda/Scripts, but you could place it in any folder and add that folder to the path.

System.out.println("Element "+i+list.get(0));}

Should be

System.out.println("Element "+i+list.get(i));}

To use the JSF tags, you give the dataList value attribute a reference to your list of elements, and the var attribute is a local name for each element of that list in turn. Inside the dataList, you use properties of the object (getters) to output the information about that individual object:

<t:dataList id="myDataList" value="#{houseControlList}" var="element" rows="3" >
...
<t:outputText id="houseId" value="#{element.houseId}"/>
...
</t:dataList>

I think this solution is handy if you can test the value of the error field later. This is also applicable by creating a temporary table and returning a list of errors.

DROP PROCEDURE IF EXISTS $procName;
DELIMITER //
CREATE PROCEDURE $procName($params)
BEGIN
    DECLARE error INT DEFAULT 0;
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET error = 1;
    SELECT
       $fields
    FROM $tables
    WHERE $where
    ORDER BY $sorting LIMIT 1
    INTO $vars;
    IF error = 0 THEN
       SELECT $vars;
    ELSE
       SELECT 1 AS error;
       SET @error = 0;
    END IF;
END//
CALL $procName($effp);

Then tell read.table not to use row.names:

systems <- read.table("http://getfile.pl?test.csv", 
                      header=TRUE, sep=",", row.names=NULL)

and now your rows will simply be numbered.

Also look at read.csv which is a wrapper for read.table which already sets the sep=',' and header=TRUE arguments so that your call simplifies to

systems <- read.csv("http://getfile.pl?test.csv", row.names=NULL)

all you need to do is to type chrome://restart in the address bar and chrome, with all its apps that are running in background, will restart and the Auth password cache will be cleaned.

With Git 2.30 (Q1 2021), there will be a new merge strategy: ORT ("Ostensibly Recursive's Twin").

git merge -s ort

This comes from this thread from Elijah Newren:

For now, I'm calling it "Ostensibly Recursive's Twin", or "ort" for short. > At first, people shouldn't be able to notice any difference between it and the current recursive strategy, other than the fact that I think I can make it a bit faster (especially for big repos).

But it should allow me to fix some (admittedly corner case) bugs that are harder to handle in the current design, and I think that a merge that doesn't touch $GIT_WORK_TREE or $GIT_INDEX_FILE will allow for some fun new features.
That's the hope anyway.

Problem:

In the ideal world, we should:

• ask unpack_trees() to do "read-tree -m" without "-u";

• do all the merge-recursive computations in-core and prepare the resulting index, while keeping the current index intact;

• compare the current in-core index and the resulting in-core index, and notice the paths that need to be added, updated or removed in the working tree, and ensure that there is no loss of information when the change is reflected to the working tree;
  E.g. the result wants to create a file where the working tree currently has a directory with non-expendable contents in it, the result wants to remove a file where the working tree file has local modification, etc.;
  And then finally

• carry out the working tree update to make it match what the resulting in-core index says it should look like.

Result:

See commit 14c4586 (02 Nov 2020), commit fe1a21d (29 Oct 2020), and commit 47b1e89, commit 17e5574 (27 Oct 2020) by Elijah Newren (newren).

merge-ort: barebones API of new merge strategy with empty implementation

^{Signed-off-by: Elijah Newren}

This is the beginning of a new merge strategy.

While there are some API differences, and the implementation has some differences in behavior, it is essentially meant as an eventual drop-in replacement for merge-recursive.c.

However, it is being built to exist side-by-side with merge-recursive so that we have plenty of time to find out how those differences pan out in the real world while people can still fall back to merge-recursive.
(Also, I intend to avoid modifying merge-recursive during this process, to keep it stable.)

The primary difference noticable here is that the updating of the working tree and index is not done simultaneously with the merge algorithm, but is a separate post-processing step.
The new API is designed so that one can do repeated merges (e.g. during a rebase or cherry-pick) and only update the index and working tree one time at the end instead of updating it with every intermediate result.

Also, one can perform a merge between two branches, neither of which match the index or the working tree, without clobbering the index or working tree.

And:

t6423, t6436: note improved ort handling with dirty files

^{Signed-off-by: Elijah Newren}

The "recursive" backend relies on unpack_trees() to check if unstaged changes would be overwritten by a merge, but unpack_trees() does not understand renames -- and once it returns, it has already written many updates to the working tree and index.
As such, "recursive" had to do a special 4-way merge where it would need to also treat the working copy as an extra source of differences that we had to carefully avoid overwriting and resulting in moving files to new locations to avoid conflicts.

The "ort" backend, by contrast, does the complete merge inmemory, and only updates the index and working copy as a post-processing step.
If there are dirty files in the way, it can simply abort the merge.

t6423: expect improved conflict markers labels in the ort backend

^{Signed-off-by: Elijah Newren}

Conflict markers carry an extra annotation of the form REF-OR-COMMIT:FILENAME to help distinguish where the content is coming from, with the :FILENAME piece being left off if it is the same for both sides of history (thus only renames with content conflicts carry that part of the annotation).

However, there were cases where the :FILENAME annotation was accidentally left off, due to merge-recursive's every-codepath-needs-a-copy-of-all-special-case-code format.

t6404, t6423: expect improved rename/delete handling in ort backend

^{Signed-off-by: Elijah Newren}

When a file is renamed and has content conflicts, merge-recursive does not have some stages for the old filename and some stages for the new filename in the index; instead it copies all the stages corresponding to the old filename over to the corresponding locations for the new filename, so that there are three higher order stages all corresponding to the new filename.

Doing things this way makes it easier for the user to access the different versions and to resolve the conflict (no need to manually 'git rm '^(man) the old version as well as 'git add'^(man) the new one).

rename/deletes should be handled similarly -- there should be two stages for the renamed file rather than just one.
We do not want to destabilize merge-recursive right now, so instead update relevant tests to have different expectations depending on whether the "recursive" or "ort" merge strategies are in use.

With Git 2.30 (Q1 2021), Preparation for a new merge strategy.

merge tests: expect improved directory/file conflict handling in ort

^{Signed-off-by: Elijah Newren}

merge-recursive.c is built on the idea of running unpack_trees() and then "doing minor touch-ups" to get the result.
Unfortunately, unpack_trees() was run in an update-as-it-goes mode, leading merge-recursive.c to follow suit and end up with an immediate evaluation and fix-it-up-as-you-go design.

Some things like directory/file conflicts are not well representable in the index data structure, and required special extra code to handle.
But then when it was discovered that rename/delete conflicts could also be involved in directory/file conflicts, the special directory/file conflict handling code had to be copied to the rename/delete codepath.
...and then it had to be copied for modify/delete, and for rename/rename(1to2) conflicts, ...and yet it still missed some.
Further, when it was discovered that there were also file/submodule conflicts and submodule/directory conflicts, we needed to copy the special submodule handling code to all the special cases throughout the codebase.

And then it was discovered that our handling of directory/file conflicts was suboptimal because it would create untracked files to store the contents of the conflicting file, which would not be cleaned up if someone were to run a 'git merge --abort'^(man) or 'git rebase --abort'^(man).

It was also difficult or scary to try to add or remove the index entries corresponding to these files given the directory/file conflict in the index.
But changing merge-recursive.c to handle these correctly was a royal pain because there were so many sites in the code with similar but not identical code for handling directory/file/submodule conflicts that would all need to be updated.

I have worked hard to push all directory/file/submodule conflict handling in merge-ort through a single codepath, and avoid creating untracked files for storing tracked content (it does record things at alternate paths, but makes sure they have higher-order stages in the index).

With Git 2.31 (Q1 2021), the merge backend "done right" starts to emerge.
Example:

See commit 6d37ca2 (11 Nov 2020) by Junio C Hamano (gitster).

merge-ort: add implementation of record_conflicted_index_entries()

^{Signed-off-by: Elijah Newren}

After checkout(), the working tree has the appropriate contents, and the index matches the working copy.
That means that all unmodified and cleanly merged files have correct index entries, but conflicted entries need to be updated.

We do this by looping over the conflicted entries, marking the existing index entry for the path with CE_REMOVE, adding new higher order staged for the path at the end of the index (ignoring normal index sort order), and then at the end of the loop removing the CE_REMOVED-marked cache entries and sorting the index.

With Git 2.31 (Q1 2021), rename detection is added to the "ORT" merge strategy.

See commit 6fcccbd, commit f1665e6, commit 35e47e3, commit 2e91ddd, commit 53e88a0, commit af1e56c (15 Dec 2020), and commit c2d267d, commit 965a7bc, commit f39d05c, commit e1a124e, commit 864075e (14 Dec 2020) by Elijah Newren (newren).

Example:

merge-ort: add implementation of normal rename handling

^{Signed-off-by: Elijah Newren}

Implement handling of normal renames.
This code replaces the following from merge-recurisve.c:

• the code relevant to RENAME_NORMAL in process_renames()
• the RENAME_NORMAL case of process_entry()

Also, there is some shared code from merge-recursive.c for multiple different rename cases which we will no longer need for this case (or other rename cases):

• handle_rename_normal()
• setup_rename_conflict_info()

The consolidation of four separate codepaths into one is made possible by a change in design: process_renames() tweaks the conflict_info entries within opt->priv->paths such that process_entry() can then handle all the non-rename conflict types (directory/file, modify/delete, etc.) orthogonally.

This means we're much less likely to miss special implementation of some kind of combination of conflict types (see commits brought in by 66c62ea ("Merge branch 'en/merge-tests'", 2020-11-18, Git v2.30.0-rc0 -- merge listed in batch #6), especially commit ef52778 ("merge tests: expect improved directory/file conflict handling in ort", 2020-10-26, Git v2.30.0-rc0 -- merge listed in batch #6) for more details).

That, together with letting worktree/index updating be handled orthogonally in the merge_switch_to_result() function, dramatically simplifies the code for various special rename cases.

(To be fair, the code for handling normal renames wasn't all that complicated beforehand, but it's still much simpler now.)

And, still with Git 2.31 (Q1 2021), With Git 2.31 (Q1 2021), oRT merge strategy learns more support for merge conflicts.

See commit 4ef88fc, commit 4204cd5, commit 70f19c7, commit c73cda7, commit f591c47, commit 62fdec1, commit 991bbdc, commit 5a1a1e8, commit 23366d2, commit 0ccfa4e (01 Jan 2021) by Elijah Newren (newren).

merge-ort: add handling for different types of files at same path

^{Signed-off-by: Elijah Newren}

Add some handling that explicitly considers collisions of the following types:

• file/submodule
• file/symlink
• submodule/symlink> Leaving them as conflicts at the same path are hard for users to resolve, so move one or both of them aside so that they each get their own path.

Note that in the case of recursive handling (i.e.
call_depth > 0), we can just use the merge base of the two merge bases as the merge result much like we do with modify/delete conflicts, binary files, conflicting submodule values, and so on.

If you only need to find a free port for later use, here is a snippet similar to a previous answer, but shorter, using socketserver:

import socketserver

with socketserver.TCPServer(("localhost", 0), None) as s:
    free_port = s.server_address[1]

Note that the port is not guaranteed to remain free, so you may need to put this snippet and the code using it in a loop.

You can get all tables that has column "Product" from information_Schema.columns

SELECT DISTINCT table_name FROM information_schema.columns WHERE column_name ="Product";

Nor create a procedure

delimiter //
CREATE PROCEDURE curdemo()
BEGIN
  DECLARE a varchar(100); 
  DECLARE cur1 CURSOR FOR SELECT DISTINCT table_name FROM information_schema.columns WHERE column_name ="Product";
  OPEN cur1;

  read_loop: LOOP
    FETCH cur1 INTO a;

    SELECT * FROM a;

  END LOOP;

  CLOSE cur1;
END;

delimiter ;

call curdemo();

This is known as a line magic in iPython. They are unique in that their arguments only extend to the end of the current line, and magics themselves are really structured for command line development. timeit is used to time the execution of code.

If you wanted to see all of the magics you can use, you could simply type:

%lsmagic

to get a list of both line magics and cell magics.

Some further magic information from documentation here:

IPython has a system of commands we call magics that provide effectively a mini command language that is orthogonal to the syntax of Python and is extensible by the user with new commands. Magics are meant to be typed interactively, so they use command-line conventions, such as using whitespace for separating arguments, dashes for options and other conventions typical of a command-line environment.

Depending on whether you are in line or cell mode, there are two different ways to use %timeit. Your question illustrates the first way:

In [1]: %timeit range(100)

vs.

In [1]: %%timeit 
      : x = range(100)

I did try giving access to the folders but that did not help. My solution was to make the below highlighted options in red selected for the logged in user

With trackerless/DHT torrents, peer IP addresses are stored in the DHT using the BitTorrent infohash as the key. Since all a tracker does, basically, is respond to put/get requests, this functionality corresponds exactly to the interface that a DHT (distributed hash table) provides: it allows you to look up and store IP addresses in the DHT by infohash.

So a "get" request would look up a BT infohash and return a set of IP addresses. A "put" stores an IP address for a given infohash. This corresponds to the "announce" request you would otherwise make to the tracker to receive a dictionary of peer IP addresses.

In a DHT, peers are randomly assigned to store values belonging to a small fraction of the key space; the hashing ensures that keys are distributed randomly across participating peers. The DHT protocol (Kademlia for BitTorrent) ensures that put/get requests are routed efficiently to the peers responsible for maintaining a given key's IP address lists.

//Get solution for ng-repeat    
//Add variable and assign with Object.key

    export class TestComponent implements OnInit{
      objectKeys = Object.keys;
      obj: object = {
        "test": "value"
        "test1": "value1"
        }
    }
    //HTML
      <div *ngFor="let key of objectKeys(obj)">
        <div>

The following should work fine.

Among bash one-liner I think this is the prettiest:

svn status | tee >(awk '/^?/{print $2}' | xargs -r svn add >&2) | awk '/^!/{print $2}' | xargs -r svn delete

It will add all new files and delete all missing files. Use with caution, possibly set an alias for quick access.

NOTE for Macs: in xargs -r is a GNU extension: it might not be supported. In that case just remove it and ignore warnings when there are no files to add or to delete

This pulls back client info as well.

var get = function(u){
    var x = new XMLHttpRequest;
    x.open('GET', u, false);
    x.send();
    return x.responseText;
}

JSON.parse(get('http://ifconfig.me/all.json'))

You can also rebuild your string character by character, excluding the characters that you want to get rid of.

Here's an extension method to do this:

    static public string RemoveAny(this string s, string charsToRemove)
    {
        var result = "";
        foreach (var c in s)
            if (charsToRemove.Contains(c))
                continue;
            else
                result += c;

        return result;
    }

It's not slick or fancy, but it works well.

Use like this:

string newString = "My_String".RemoveAny("_"); //yields "MyString"

The more correct way to do it:

select * from sales where salesDate>=@myDate and salesDate<dateadd(dd,1,@myDate)

If only the date is specified, it means total midnight. If you want to make sure intervals don't overlap, switch the between with a pair of >= and <

else if (navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.indexOf('Safari') != -1)

    {

        alert("Safari");

    }

else if (navigator.vendor == null || navigator.vendor != null)

    {

        alert("Not Apple Based Browser");

    }

You could subscribe for the onchange event on the input field:

<input type="file" id="file" name="file" />

and then:

document.getElementById('file').onchange = function() {
    // fire the upload here
};

Just adding to the other excellent answers. Scala offers two often criticized symbolic operators, /: (foldLeft) and :\ (foldRight) operators, the first being right-associative. So the following three statements are the equivalent:

( 1 to 100 ).foldLeft( 0, _+_ )
( 1 to 100 )./:( 0 )( _+_ )
( 0 /: ( 1 to 100 ) )( _+_ )

As are these three:

( 1 to 100 ).foldRight( 0, _+_ )
( 1 to 100 ).:\( 0 )( _+_ )
( ( 1 to 100 ) :\ 0 )( _+_ )

0 values of basic types ⁽¹⁾⁽²⁾map to false.

Other values map to true.

This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.

It's a common error to assume that as function return values, false indicates failure. But in particular from main it's false that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.

There's no need to cast to bool for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x, works nicely. One can read !! as a “convert to bool” operator, much as --> can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)

^{1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true. For direct-initialization (8.5), a prvalue of type std::nullptr_t can be converted to a prvalue of type bool; the resulting value is false.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”}

My solution:

1. Type: git clone .
2. Copy the repository url and paste it after of git clone .
3. Move the cursor to position between git clone and https://... .
4. Delete space if it had between git clone and https://... until have git clonehttps://...
5. Re-add the space and press Enter.

If you want to insert the value of any checkbox immediately as it is being checked then this should work for you:

$(":checkbox").click(function(){
  $("#id").text(this.value)
})

http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_04_03.html

You can also use bash's character classes.

if [[ $VAR = *[[:digit:]]* ]]; then
 echo "$VAR is numeric"
else
 echo "$VAR is not numeric"
fi

Numerics will include space, the decimal point, and "e" or "E" for floating point.

But, if you specify a C-style hex number, i.e. "0xffff" or "0XFFFF", [[:digit:]] returns true. A bit of a trap here, bash allows you do to something like "0xAZ00" and still count it as a digit (isn't this from some weird quirk of GCC compilers that let you use 0x notation for bases other than 16???)

You might want to test for "0x" or "0X" before testing if it's a numeric if your input is completely untrusted, unless you want to accept hex numbers. That would be accomplished by:

if [[ ${VARIABLE:1:2} = "0x" ]] || [[ ${VARIABLE:1:2} = "0X" ]]; then echo "$VAR is not numeric"; fi

The % operator does not work in C++, when you are trying to find the remainder of two numbers which are both of the type Float or Double.

Hence you could try using the fmod function from math.h / cmath.h or you could use these lines of code to avoid using that header file:

float sin(float x) {
 float temp;
 temp = (x + M_PI) / ((2 *M_PI) - M_PI);
 return limited_sin((x + M_PI) - ((2 *M_PI) - M_PI) * temp ));

}

I'm not entirely sure what visual end result you're after, but here's an easy way to blur an image's edge: place a div with the image inside another div with the blurred image.

Working example here: http://jsfiddle.net/ZY5hn/1/

HTML:

<div class="placeholder">
     <!-- blurred background image for blurred edge -->
     <div class="bg-image-blur"></div>
     <!-- same image, no blur -->
     <div class="bg-image"></div>
     <!-- content -->
     <div class="content">Blurred Image Edges</div>
</div>

CSS:

.placeholder {
    margin-right: auto;
    margin-left:auto;
    margin-top: 20px;
    width: 200px;
    height: 200px;
    position: relative;
    /* this is the only relevant part for the example */
}
/* both DIVs have the same image */
 .bg-image-blur, .bg-image {
    background-image: url('http://lorempixel.com/200/200/city/9');
    position:absolute;
    top:0;
    left:0;
    width: 100%;
    height:100%;
}
/* blur the background, to make blurred edges that overflow the unblurred image that is on top */
 .bg-image-blur {
    -webkit-filter: blur(20px);
    -moz-filter: blur(20px);
    -o-filter: blur(20px);
    -ms-filter: blur(20px);
    filter: blur(20px);
}
/* I added this DIV in case you need to place content inside */
 .content {
    position: absolute;
    top:0;
    left:0;
    width: 100%;
    height: 100%;
    color: #fff;
    text-shadow: 0 0 3px #000;
    text-align: center;
    font-size: 30px;
}

Notice the blurred effect is using the image, so it changes with the image color.

I hope this helps.

You need to use the Navigation component in the template of ObservingComponent ( dont't forget to add a selector to Navigation component .. navigation-component for ex )

<navigation-component (navchange)='onNavGhange($event)'></navigation-component>

And implement onNavGhange() in ObservingComponent

onNavGhange(event) {
  console.log(event);
}

Last thing .. you don't need the events attribute in @Componennt

events : ['navchange'], 

The ID Should have the id of the corresponding div that has the overflow css property.

document.querySelector('#YOUR_OVERFLOWED_DIV').scrollTop = 0;

Look at the ToLookup and/or ToDictionary extension methods.

One of the common problems with VLOOKUP is "data mismatch" where #N/A is returned because a numeric lookup value doesn't match a text-formatted value in the VLOOKUP table (or vice versa)

Does either of these versions work?

=VLOOKUP(M3&"",Sheet1!$A$2:$Q$47,13,FALSE)

or

=VLOOKUP(M3+0,Sheet1!$A$2:$Q$47,13,FALSE)

The former converts a numeric lookup value to text (assuming that lookup table 1st column contains numbers formatted as text). The latter does the reverse, changing a text-formatted lookup value to a number.

Depending on which one works (assuming one does) then you may want to permanently change the format of your data so that the standard VLOOKUP will work

This may be helpful if you have more than one python versions installed and dont know how to tell your ide's to use a specific version.

1. Install anaconda. Latest version can be found here
2. Open the navigator by typing anaconda-navigator in terminal
3. Open environments. Click on create and then choose your python version in that.
4. Now new environment will be created for your python version and you can install the IDE's(which are listed there) just by clicking install in that.
5. Launch the IDE in your environment so that that IDE will use the specified version for that environment.

Hope it helps!!

The new recommend way in Python3 is to use pathlib:

from pathlib import Path

mydir = Path("path/to/my/dir")
for file in mydir.glob('*.mp4'):
    print(file.name)
    # do your stuff

Instead of *.mp4 you can use any filter, even a recursive one like **/*.mp4. If you want to use more than one extension, you can simply iterate all with * or **/* (recursive) and check every file's extension with file.name.endswith(('.mp4', '.webp', '.avi', '.wmv', '.mov'))

My solution...

HTML :

<input type="file" id="uploadImages" style="display:none;" multiple>

<input type="button" id="callUploadImages" value="Select">
<input type="button" id="uploadImagesInfo" value="0 file(s)." disabled>
<input type="button" id="uploadProductImages" value="Upload">

Jquery:

$('#callUploadImages').click(function(){

    $('#uploadImages').click();
});

$('#uploadImages').change(function(){

    var uploadImages = $(this);
    $('#uploadImagesInfo').val(uploadImages[0].files.length+" file(s).");
});

This is just evil :D

Select Replicate('0',2 - DataLength(Convert(VarChar(2),DatePart(DAY, GetDate()))) + Convert(VarChar(2),DatePart(DAY, GetDate())

Usually when you have to start doing this sort of thing in SQL, you need switch from can I, to should I.

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

Here's a simple example of how to load JSON data into an Angular model.

I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.

http://www.iNorthwind.com/Service1.svc/getAllCustomers

It returns some JSON data which looks like this:

{ 
    "GetAllCustomersResult" : 
        [
            {
              "CompanyName": "Alfreds Futterkiste",
              "CustomerID": "ALFKI"
            },
            {
              "CompanyName": "Ana Trujillo Emparedados y helados",
              "CustomerID": "ANATR"
            },
            {
              "CompanyName": "Antonio Moreno Taquería",
              "CustomerID": "ANTON"
            }
        ]
    }

..and I want to populate a drop down list with this data, to look like this...

I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.

How would I do it ?

My Angular controller would look like this:

function MikesAngularController($scope, $http) {

    $scope.listOfCustomers = null;

    $http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
         .success(function (data) {
             $scope.listOfCustomers = data.GetAllCustomersResult;
         })
         .error(function (data, status, headers, config) {
             //  Do some error handling here
         });
}

... which fills a "listOfCustomers" variable with this set of JSON data.

Then, in my HTML page, I'd use this:

<div ng-controller='MikesAngularController'>
    <span>Please select a customer:</span>
    <select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>

And that's it. We can now see a list of our JSON data on a web page, ready to be used.

The key to this is in the "ng-options" tag:

customer.CustomerID as customer.CompanyName for customer in listOfCustomers

It's a strange syntax to get your head around !

When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.

The full script for this example can be found here:

Tip #84: Did you know… How to set a Start page for your Web Site in Visual Web Developer?

Simply right click on the page you want to be the start page and say "set as start page".

As noted in the comment below by Adam Tuliper - MSFT, this only works for debugging, not deployment.

I find this way more readable:

$result = $mysqli->query('select count(*) as `c` from `table`');
$count = $result->fetch_object()->c;
echo "there are {$count} rows in the table";

Not that I have anything against arrays...

You need to add a CDATA tag inside of the script tag, unless you want to manually go through and escape all XHTML characters (e.g. & would need to become &). For example:

<script>
//<![CDATA[
var el = document.getElementById("pacman");

if (Modernizr.canvas && Modernizr.localstorage && 
    Modernizr.audio && (Modernizr.audio.ogg || Modernizr.audio.mp3)) {
  window.setTimeout(function () { PACMAN.init(el, "./"); }, 0);
} else { 
  el.innerHTML = "Sorry, needs a decent browser<br /><small>" + 
    "(firefox 3.6+, Chrome 4+, Opera 10+ and Safari 4+)</small>";
}
//]]>
</script>

Inspired by Eric's answer, here is my solution to this problem for selenium 3.7.0. Compared with the solution at http://tarunlalwani.com/post/reusing-existing-browser-session-selenium/, the advantage is that there won't be a blank browser window each time I connect to the existing session.

The Python documentation does explain it.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

Unfortunately there is not cross browser JavaScript support for trim().

If you aren't using jQuery (which has a .trim() method) you can use the following methods to add trim support to strings:

String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g,"");
}
String.prototype.ltrim = function() {
    return this.replace(/^\s+/,"");
}
String.prototype.rtrim = function() {
    return this.replace(/\s+$/,"");
}

Yes for some reason WebView.reload() causes a crash if it failed to load before (something to do with the way it handles history). This is the code I use to refresh my webview. I store the current url in self.url

# 1: Pause timeout and page loading

self.timeout.pause()
sleep(1)

# 2: Check for internet connection (Really lazy way)

while self.page().networkAccessManager().networkAccessible() == QNetworkAccessManager.NotAccessible: sleep(2)

# 3:Try again

if self.url == self.page().mainFrame().url():
    self.page().action(QWebPage.Reload)
    self.timeout.resume(60)

else:
    self.page().action(QWebPage.Stop)
    self.page().mainFrame().load(self.url)
    self.timeout.resume(30)

return False

What browser are you testing in?

What DOCType have you set?

How exactly are you declaring your CSS?

Are you sure you haven't missed a ; before/after the overflow-y: scroll?

I've just tested the following in IE7 and Firefox and it works fine

<!-- Scroll bar present but disabled when less content -->_x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test_x000D_
</div>_x000D_
_x000D_
<!-- Scroll bar present and enabled when more contents -->        _x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
</div>

We don't need to bother entering the current line number.

If you would like to change each foo to bar for current line (.) and the two next lines (+2), simply do:

:.,+2s/foo/bar/g

If you want to confirm before changes are made, replace g with gc:

:.,+2s/foo/bar/gc

Like vikingosgundo said, but keep in mind that if you use [UIImage imageNamed:image] then the image is cached and eats away memory. So unless you plan on using the same image in many places, you should load the image, with imageWithContentsOfFile: and imageWithData:

This will save you significant memory and speeds up your app.

So far as I know there's no single function which does this (maybe you were looking for the inverse of MapPath?). I'd love to know if such a function exists. Until then, I would just take the filename(s) returned by GetFiles, remove the path, and prepend the URL root. This can be done generically.

As a follow-up to this question - since it relates specifically to creation time and discusses obtaining it via the new nio classes - it seems right now in JDK7's implementation you're out of luck. Addendum: same behaviour is in OpenJDK7.

On Unix filesystems you cannot retrieve the creation timestamp, you simply get a copy of the last modification time. So sad, but unfortunately true. I'm not sure why that is but the code specifically does that as the following will demonstrate.

import java.io.IOException;
import java.nio.file.*;
import java.nio.file.attribute.*;

public class TestFA {
  static void getAttributes(String pathStr) throws IOException {
    Path p = Paths.get(pathStr);
    BasicFileAttributes view
       = Files.getFileAttributeView(p, BasicFileAttributeView.class)
              .readAttributes();
    System.out.println(view.creationTime()+" is the same as "+view.lastModifiedTime());
  }
  public static void main(String[] args) throws IOException {
    for (String s : args) {
        getAttributes(s);
    }
  }
}

str.startswith allows you to supply a tuple of strings to test for:

if link.lower().startswith(("js", "catalog", "script", "katalog")):

From the docs:

str.startswith(prefix[, start[, end]])

Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for.

Below is a demonstration:

>>> "abcde".startswith(("xyz", "abc"))
True
>>> prefixes = ["xyz", "abc"]
>>> "abcde".startswith(tuple(prefixes)) # You must use a tuple though
True
>>>

Maybe via JavaScriptSerializer.Serialize?

Explanation from the Preshing on Programming blog:

It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:

 with open('output.txt', 'w') as f:
     f.write('Hi there!')

The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.

Are you concerned about the profile picture size? at the time of implementing login with Facebook using PHP. We’ll show you the simple way to get large size profile picture in Facebook PHP SDK. Also, you can get the custom size image of Facebook profile.

Set the profile picture dimension by using the following line of code.

$userProfile = $facebook->api('/me?fields=picture.width(400).height(400)');

check this post:http://www.codexworld.com/how-to-guides/get-large-size-profile-picture-in-facebook-php-sdk/

numpy.ndarray can contain any type of element, e.g. int, float, string etc. Check the type an do a conversion if neccessary.

If you ever want to check what locale or character set java is using this is built into the JVM:

java -XshowSettings -version

and it will dump out loads of the settings it's using. This way you can check your LANG and LC_* values are getting picked up correctly.

dictionary's setdefault is a good way to update an existing dict entry if it's there, or create a new one if it's not all in one go:

Looping style:

# This is our sample data
data = [("Milter", "Miller", 4), ("Milter", "Miler", 4), ("Milter", "Malter", 2)]

# dictionary we want for the result
dictionary = {}

# loop that makes it work
for realName, falseName, position in data:
    dictionary.setdefault(realName, {})[falseName] = position

dictionary now equals:

{'Milter': {'Malter': 2, 'Miler': 4, 'Miller': 4}}

As Mike Sokolov has already pointed it out, one of the possible reasons is presence of some character/s (such as a whitespace) before the tag.

If your input XML is being read as a String (as opposed to byte array) then you can use replace your input string with the below code to make sure that all 'un-necessary' characters before the xml tag are wiped off.

inputXML=inputXML.substring(inputXML.indexOf("<?xml"));

You need to be sure that the input xml starts with the xml tag though.

We can use

Type.GetType()

to get class name and can also create object of it using Activator.CreateInstance(type);

using System;
using System.Reflection;

namespace MyApplication
{
    class Application
    {
        static void Main()
        {
            Type type = Type.GetType("MyApplication.Action");
            if (type == null)
            {
                throw new Exception("Type not found.");
            }
            var instance = Activator.CreateInstance(type);
            //or
            var newClass = System.Reflection.Assembly.GetAssembly(type).CreateInstance("MyApplication.Action");
        }
    }

    public class Action
    {
        public string key { get; set; }
        public string Value { get; set; }
    }
}

I generally tend towards #2, As a query argument (i.e. /api/resource?parameter=value ).

A third option is to actually post the parameter=value in the body.

This is because it works better for multi parameter resources and is more extendable for future use.

No matter which one you pick, make sure you only pick one, don't mix and match. That leads towards a confusing API.

You want:

if (document.getElementById('customx').value === ""){
    //do something
}

The value property will give you a string value and you need to compare that against an empty string.

The subprocess module has come along way since 2008. In particular check_call and check_output make simple subprocess stuff even easier. The check_* family of functions are nice it that they raise an exception if something goes wrong.

import os
import subprocess

files = os.listdir('.')
for f in files:
   subprocess.check_call( [ 'myscript', f ] )

Any output generated by myscript will display as though your process produced the output (technically myscript and your python script share the same stdout). There are a couple of ways to avoid this.

• check_call( [ 'myscript', f ], stdout=subprocess.PIPE )
  The stdout will be supressed (beware if myscript produces more that 4k of output). stderr will still be shown unless you add the option stderr=subprocess.PIPE.
• check_output( [ 'myscript', f ] )
check_output returns the stdout as a string so it isnt shown. stderr is still shown unless you add the option stderr=subprocess.STDOUT.

code:

function writeData() {
    jQuery("#chatTickets input:radio[id^=ticketID]:first").attr('disabled', true);
    return false;
}

Android Reverse Engineering is possible . Follow these steps to get .java file from apk file.

Step1 . Using dex2jar

• Generate .jar file from .apk file
• command : dex2jar sampleApp.apk

Step2 . Decompiling .jar using JD-GUI

• it decompiles the .class files i.e., we'll get obfuscated .java back from the apk.

Here's a solution I coded up today for a situation where I needed to parse a CSV without relying on external libraries. I haven't tested performance for large files since it wasn't relevant to my particular use case but I'd expect it to perform reasonably well for most situations.

        static List<List<string>> ParseCsv(string csv) {
            var parsedCsv = new List<List<string>>();
            var row = new List<string>();
            string field = "";
            bool inQuotedField = false;

            for (int i = 0; i < csv.Length; i++) {
                char current = csv[i];
                char next = i == csv.Length - 1 ? ' ' : csv[i + 1];

                // if current character is not a quote or comma or carriage return or newline (or not a quote and currently in an a quoted field), just add the character to the current field text
                if ((current != '"' && current != ',' && current != '\r' && current != '\n') || (current != '"' && inQuotedField)) {
                    field += current;
                } else if (current == ' ' || current == '\t') {
                    continue; // ignore whitespace outside a quoted field
                } else if (current == '"') {
                    if (inQuotedField && next == '"') { // quote is escaping a quote within a quoted field
                        i++; // skip escaping quote
                        field += current;
                    } else if (inQuotedField) { // quote signifies the end of a quoted field
                        row.Add(field);
                        if (next == ',') {
                            i++; // skip the comma separator since we've already found the end of the field
                        }
                        field = "";
                        inQuotedField = false;
                    } else { // quote signifies the beginning of a quoted field
                        inQuotedField = true; 
                    }
                } else if (current == ',') { //
                    row.Add(field);
                    field = "";
                } else if (current == '\n') {
                    row.Add(field);
                    parsedCsv.Add(new List<string>(row));
                    field = "";
                    row.Clear();
                }
            }

            return parsedCsv;
        }

Does the class org.apache.maven.shared.filtering.MavenFilteringException exist in file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar?

The error message suggests that it doesn't. Maybe the JAR was corrupted somehow.

I'm also wondering where the version 1.0-beta-2 comes from; I have 1.0 on my disk. Try version 2.3 of the WAR plugin.

I just replaced version 11.2.0 with 11.0.0 and then it seemed to work fine, so that had to mean that 11.2.0 wasn't included with the latest Android SDK.

So, after struggling with all the available scattered documentation, I reached this document by pure chance (I guess it is not indexed high enough by Google): https://developers.google.com/android/guides/releases

I quote from there:

Highlights from the Google Play services 11.2 release. Google Play services dependencies are now available via maven.google.com

Now, even when that shouldn't necessarily mean that they are not available with the downloaded SDK anymore, it seems that this is actually the case.

Anyway, adding google() to my build.gradle didn't work (not found, undefined, or whatever...), so I used a different approach that I found in this document referenced from the previous one:

https://developer.android.com/studio/build/dependencies.html#google-maven

I modified my build.gradle file adding that line to allprojects/repositories, as in:

allprojects {
...
    repositories {
...
        maven { url "https://maven.google.com/"}
    }
}

And then also in the android section in the same build.gradle file:

project(":android") {
...
    dependencies {
...
        compile 'com.google.android.gms:play-services-ads:11.2.0'
    }
}

Those two lines were enough to make Gradle sync without problems. I didn't need to add any plugins apart from the ones that are already added in my libGDX project by default.

After that, I got a few different errors, but none about Gradle or dependencies. In a brief, JFTR:

First, I had a minSdkVersion of 8. Solved by raising it to 14. I think I could live without supporting all those devices below 14.

Second, I had problems with the dex upper limit of references. I've never faced this problem before, but maybe you've already noticed the solution I used: instead of compiling the whole 'com.google.android.gms:play-services' I used only 'com.google.android.gms:play-services-ads' that's the API I'm actually interested right now. For those other particular cases where a solution like this may not be useful, this document could provide some better insight: https://developer.android.com/studio/build/multidex.html

Third, even after that I got this "jumbo" thing problem described and answered here: https://stackoverflow.com/a/26248495/1160360

And that's it. As of now, everything builds and my game does finally shows those Admob banners.

I've spent hours with this, thought, which makes me wonder if all these building automation systems we are using lately are worth the extra load they add.

I mean, the first time I had to add Admob to an app five years ago or so, I just had to download a .jar file and put it on a directory on my project. It was pretty obvious and the whole process, from googling "how to setup Admob in my android project" to have my app showing an Admob banner took me just a few minutes. I'm gonna leave it here, since this is not the place for such kind of debate.

Nonetheless, I hope my own experience is useful for someone else further.

Yes , Jared and Kelly Orr are right. I use the following code like in edit exception.

foreach (var issue in dinner.GetRuleViolations())
{
    ModelState.AddModelError(issue.PropertyName, issue.ErrorMessage);
}

in stead of

ModelState.AddRuleViolations(dinner.GetRuleViolations());

I think a good place to start is with Ninject, it is new and has taken into account alot of fine tuning and is really fast. Nate, the developer, really has a great site and great support.

As per recent version. You need to go advanced settings. In this section you will find the un-publish button.

My experience is, that NIO is much faster with small files. But when it comes to large files FileInputStream/FileOutputStream is much faster.

 var agencias = [];
 $('#Div input:checked').each(function(index, item){
 agencias.push(item.nextElementSibling.attributes.for.nodeValue);
 });

Use convert with style 101.

select convert(datetime, Remarks, 101)

If your column is really text you need to convert to varchar before converting to datetime

select convert(datetime, convert(varchar(30), Remarks), 101)

It's empty by default. You'll find a bunch of settings in /etc/apache2/apache2.conf.

In there it does this:

GCC compiles a C/C++ program into executable in 4 steps.

For example, gcc -o hello hello.c is carried out as follows:

1. Pre-processing

Preprocessing via the GNU C Preprocessor (cpp.exe), which includes the headers (#include) and expands the macros (#define).

cpp hello.c > hello.i

The resultant intermediate file "hello.i" contains the expanded source code.

2. Compilation

The compiler compiles the pre-processed source code into assembly code for a specific processor.

gcc -S hello.i

The -S option specifies to produce assembly code, instead of object code. The resultant assembly file is "hello.s".

3. Assembly

The assembler (as.exe) converts the assembly code into machine code in the object file "hello.o".

as -o hello.o hello.s

4. Linker

Finally, the linker (ld.exe) links the object code with the library code to produce an executable file "hello".

    ld -o hello hello.o ...libraries...

With Spark 2.x and Scala 2.11

I'd think of 3 possible ways to convert values of a specific column to List.

Common code snippets for all the approaches

import org.apache.spark.sql.SparkSession

val spark = SparkSession.builder.getOrCreate    
import spark.implicits._ // for .toDF() method

val df = Seq(
    ("first", 2.0),
    ("test", 1.5), 
    ("choose", 8.0)
  ).toDF("id", "val")

Approach 1

df.select("id").collect().map(_(0)).toList
// res9: List[Any] = List(one, two, three)

What happens now? We are collecting data to Driver with collect() and picking element zero from each record.

This could not be an excellent way of doing it, Let's improve it with next approach.

Approach 2

df.select("id").rdd.map(r => r(0)).collect.toList 
//res10: List[Any] = List(one, two, three)

How is it better? We have distributed map transformation load among the workers rather than single Driver.

I know rdd.map(r => r(0)) does not seems elegant you. So, let's address it in next approach.

Approach 3

df.select("id").map(r => r.getString(0)).collect.toList 
//res11: List[String] = List(one, two, three)

Here we are not converting DataFrame to RDD. Look at map it won't accept r => r(0)(or _(0)) as the previous approach due to encoder issues in DataFrame. So end up using r => r.getString(0) and it would be addressed in the next versions of Spark.

Conclusion

All the options give the same output but 2 and 3 are effective, finally 3rd one is effective and elegant(I'd think).

Databricks notebook

foreach (var item in dicNumber)
{
    listnumber.Add(item.Key);
}

var elem = document.querySelector(".a.b");

The general format, from the @link section of the javadoc documentation, is:

Examples

Method in the same class:

/** See also {@link #myMethod(String)}. */
void foo() { ... }

Method in a different class, either in the same package or imported:

/** See also {@link MyOtherClass#myMethod(String)}. */
void foo() { ... }

Method in a different package and not imported:

/** See also {@link com.mypackage.YetAnotherClass#myMethod(String)}. */
void foo() { ... }

Label linked to method, in plain text rather than code font:

/** See also this {@linkplain #myMethod(String) implementation}. */
void foo() { ... }

A chain of method calls, as in your question. We have to specify labels for the links to methods outside this class, or we get getFoo().Foo.getBar().Bar.getBaz(). But these labels can be fragile during refactoring -- see "Labels" below.

/**
 * A convenience method, equivalent to 
 * {@link #getFoo()}.{@link Foo#getBar() getBar()}.{@link Bar#getBaz() getBaz()}.
 * @return baz
 */
public Baz fooBarBaz()

Labels

Automated refactoring may not affect labels. This includes renaming the method, class or package; and changing the method signature.

Therefore, provide a label only if you want different text than the default.

For example, you might link from human language to code:

/** You can also {@linkplain #getFoo() get the current foo}. */
void setFoo( Foo foo ) { ... }

Or you might link from a code sample with text different than the default, as shown above under "A chain of method calls." However, this can be fragile while APIs are evolving.

Type erasure and #member

If the method signature includes parameterized types, use the erasure of those types in the javadoc @link. For example:

int bar( Collection<Integer> receiver ) { ... }

/** See also {@link #bar(Collection)}. */
void foo() { ... }

On Java 14 you can do this

List<String> strings = Arrays.asList("one", "two", "three");

In case you want to set a HTML string and avoid the bottom padding, please make sure that you are not using block tags i.e. div, p.

In my case this was the reason. You can easily test it out by replacing occurrences of block tags with i.e. span tag.

Since my related question was removed by a righteous hand after I had killed the whole day searching how to beat the "macro not found or disabled" error, posting here the only syntax that worked for me (application.run didn't, no matter what I tried)

Set objExcel = CreateObject("Excel.Application")

' Didn't run this way from the Modules
'objExcel.Application.Run "c:\app\Book1.xlsm!Sub1"
' Didn't run this way either from the Sheet
'objExcel.Application.Run "c:\app\Book1.xlsm!Sheet1.Sub1"
' Nor did it run from a named Sheet
'objExcel.Application.Run "c:\app\Book1.xlsm!Named_Sheet.Sub1"

' Only ran like this (from the Module1)

Set objWorkbook = objExcel.Workbooks.Open("c:\app\Book1.xlsm")
objExcel.Run "Sub1"

The latest SDKs (beginning with 2.2, I believe), include TV-Out functionality. With a special cable connected to the iPhone dock connector, a program can send RCA signals representing its current screen contents through the iPhone->RCA cable. If you have a TV Tuner for your computer (i.e. I have an EyeTV Hybrid) with RCA inputs, you can display the screen contents of your iPhone directly in the TV viewer.

I think you have to go for

$arrayname[indexname] = $value;

Had the same problem when updating my mac to macOS Catalina, while using pipenv. Pipenv creates and manages a virtualenv for you, so the earlier suggestion from @Anoop-Malav is the same, just using pipenv to remove the virtual environment based on the current dir and reset it:

pipenv --rm
pipenv shell  # recreate a virtual env with your current Pipfile

whenever you deal with spaces in filenames, use quotes

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes

Under Apache 2+ you can simply do as below (Using Linux Terminal):

sudo a2enmod rewrite && sudo service apache2 restart

or

sudo a2enmod rewrite && sudo /etc/init.d/apache2 restart

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

Why controllers are needed

The difference between link and controller comes into play when you want to nest directives in your DOM and expose API functions from the parent directive to the nested ones.

From the docs:

Best Practice: use controller when you want to expose an API to other directives. Otherwise use link.

Say you want to have two directives my-form and my-text-input and you want my-text-input directive to appear only inside my-form and nowhere else.

In that case, you will say while defining the directive my-text-input that it requires a controller from the parent DOM element using the require argument, like this: require: '^myForm'. Now the controller from the parent element will be injected into the link function as the fourth argument, following $scope, element, attributes. You can call functions on that controller and communicate with the parent directive.

Moreover, if such a controller is not found, an error will be raised.

Why use link at all

There is no real need to use the link function if one is defining the controller since the $scope is available on the controller. Moreover, while defining both link and controller, one does need to be careful about the order of invocation of the two (controller is executed before).

However, in keeping with the Angular way, most DOM manipulation and 2-way binding using $watchers is usually done in the link function while the API for children and $scope manipulation is done in the controller. This is not a hard and fast rule, but doing so will make the code more modular and help in separation of concerns (controller will maintain the directive state and link function will maintain the DOM + outside bindings).

Character varying is different than text. Try running

ALTER TABLE product_product ALTER COLUMN code TYPE text;

That will change the column type to text, which is limited to some very large amount of data (you would probably never actually hit it.)

This means that somewhere else in your code, you have something like:

sum = 0

Which shadows the builtin sum (which is callable) with an int (which isn't).

You needed to do it like this:

<h2 style="text-align: center;font-family: Tahoma">TITLE</h2>

Hope it helped.

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

You need to specify the system property with the path the .exe when starting the Selenium server node. See also the accepted anwser to Selenium grid with Chrome driver (WebDriverException: The path to the driver executable must be set by the webdriver.chrome.driver system property)

I know this is old, but I'm gonna chime in anyway because it may be useful to someone. If you can still see the file in Finder, then click on the file in your project and delete it, selecting "remove references" and not "move to trash".

Once the reference is removed, drag and drop the file from finder into your project again and it should sort itself out.

In Bootstrap 4.1.3:

This worked for me when I was trying to center a bootstrap badge inside of a container > row > column next to a h1 title.

What did work was some simple css:

.my-valign-center {
  vertical-align: 50%;
}

or

<span class="badge badge-pill" style="vertical-align: 50%;">My Badge</span>

function getOriginalWidthOfImg(img_element) {
    var t = new Image();
    t.src = (img_element.getAttribute ? img_element.getAttribute("src") : false) || img_element.src;
    return t.width;
}

You don't need to remove style from the image or image dimensions attributes. Just create an element with javascript and get the created object width.

As many users has said, you just have to change your Git repository URL from HTTPS to SSH.

If you haven't generated a SSH key in your machine, then your are going to have to do it.

Just as an additional information, after doing this change I still was getting the same error:

Permission Denied.

In my case, the problem was that I was using the Windows Shell to execute the ngh command; since this command should open a prompt to request the SSH phrase and the Windows Shell doesn't open these kinds of prompts, the authentication just failed.

So, I just had to open the Git shell and execute the ngh command there, put the SSH phrase in the prompt every time it asked for it and "voilà"... It just worked fine!

Java's Calendar representation is not the best, they are working on it for Java 8. I would advise you to use Joda Time or another similar library.

Here is a quick example using LocalDate from the Joda Time library:

LocalDate localDate = new LocalDate(year, month, day);
Date date = localDate.toDate();

Here you can follow a quick start tutorial.

SSL certificates are bound to a 'common name', which is usually a fully qualified domain name but can be a wildcard name (eg. *.domain.com) or even an IP address, but it usually isn't.

In your case, you are accessing your LDAP server by a hostname and it sounds like your two LDAP servers have different SSL certificates installed. Are you able to view (or download and view) the details of the SSL certificate? Each SSL certificate will have a unique serial numbers and fingerprint which will need to match. I assume the certificate is being rejected as these details don't match with what's in your certificate store.

Your solution will be to ensure that both LDAP servers have the same SSL certificate installed.

BTW - you can normally override DNS entries on your workstation by editing a local 'hosts' file, but I wouldn't recommend this.

I found it hard to decipher what is meant by "working directory of the VM". In my example, I was using the Java Service Wrapper program to execute a jar - the dump files were created in the directory where I had placed the wrapper program, e.g. c:\myapp\bin. The reason I discovered this is because the files can be quite large and they filled up the hard drive before I discovered their location.

var str = "  my awesome string   "
str.trim();    

for old browsers, use regex

str = str.replace(/^[ ]+|[ ]+$/g,'')
//str = "my awesome string" 

You can create a simple rule by doing something like this:

jQuery.validator.addMethod("greaterThanZero", function(value, element) {
    return this.optional(element) || (parseFloat(value) > 0);
}, "* Amount must be greater than zero");

And then applying this like so:

$('validatorElement').validate({
    rules : {
        amount : { greaterThanZero : true }
    }
});

Just change the contents of the 'addMethod' to validate your checkboxes.

Thread is a class, not an instance; currentThread() is a static method that returns the Thread instance corresponding to the calling thread.

I've just learned of a handy packaging tool called fpm recently. Stumbling upon this question I thought I might give it a try. Turns out, after reading @OrwellHindenberg's answer, it's easy to package maven into an RPM with fpm.

yum install -y gcc make rpm-build ruby-devel rubygems
gem install fpm

create a project directory and layout the directory structure of the package

mkdir maven-build
cd maven-build
mkdir -p etc/profile.d opt

create a file that we'll install to /etc/profile.d/maven.sh, we'll store this under the newly created etc/profile.d directory as maven.sh, with the following contents

export M3_HOME=/opt/apache-maven-3.1.0
export M3=$M3_HOME/bin
export PATH=$M3:$PATH

download and unpack the latest maven in the opt directory

wget http://www.eng.lsu.edu/mirrors/apache/maven/maven-3/3.1.0/binaries/apache-maven-3.1.0-bin.tar.gz
tar -xzf apache-maven-3.1.0-bin.tar.gz -C opt

finally, build the RPM

fpm -n maven-3.1.0 -s dir -t rpm etc opt

Now you can install maven through rpm

$ rpm -Uvh maven-3.1.0-1.0-1.x86_64.rpm 
Preparing...                ########################################### [100%]
   1:maven-3.1.0            ########################################### [100%]

and viola

$ which mvn
/opt/apache-maven-3.1.0/bin/mvn

not quite yum but closer to home ;)

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

It is very easy to add a new font on your existing iOS App.

You just need to add the font e.g. font.ttf into your Resource Folder.

Open your application info.plist. Add a new row as "Fonts provided by application" and type the font name as font.ttf.

And when setting the font do as setFont:"corresponding Font Name"

You can check whether your font is added or not by NSArray *check = [UIFont familyNames];.

It returns all the font your application support.

If you are using ndk r10c or later, simply add APP_STL=c++_static to Application.mk

Best practice of getting length is use length filter returns the number of items of a sequence or mapping, or the length of a string. For example: {{ notcount | length }}

But you can calculate count of elements in for loop. For example:

{% set count = 0 %}
{% for nc in notcount %}
    {% set count = count + 1 %}
{% endfor %}

{{ count }}

This solution helps if you want to calculate count of elements by condition, for example you have a property name inside object and you want to calculate count of objects with not empty names:

{% set countNotEmpty = 0 %}
{% for nc in notcount if nc.name %}
    {% set countNotEmpty = countNotEmpty + 1 %}
{% endfor %}

{{ countNotEmpty }}

Useful links:

• length
• set
• for

Just in case someone else comes across this, to clarify the answer `n is grave accent n, not single tick n

I Have faced the same issue.After a lot of struggle I found that the real issue is with the com.amazonaws dependencies.After adding dependencies this error got disappeared.

Use this syntax:

CREATE TEMPORARY TABLE t1 (select * from t2);

<script type="text/javascript" src="http://twitter.github.com/bootstrap/assets/js/bootstrap-dropdown.js"></script>

Much of this should give you compilation errors.

// note the lower case enum keyword
enum Days { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday };

Now, Saturday, Sunday, etc. can be used as top-level bare constants,and Days can be used as a type:

Days day = Saturday;   // Days.Saturday is an error

And similarly later, to test:

if (day == Saturday)
    // ...

These enum values are like bare constants - they're un-scoped - with a little extra help from the compiler: (unless you're using C++11 enum classes) they aren't encapsulated like object or structure members for instance, and you can't refer to them as members of Days.

You'll have what you're looking for with C++11, which introduces an enum class:

enum class Days
{
    SUNDAY,
    MONDAY,
    // ... etc.
}

// ...

if (day == Days::SUNDAY)
    // ...

Note that this C++ is a little different from C in a couple of ways, one is that C requires the use of the enum keyword when declaring a variable:

// day declaration in C:
enum Days day = Saturday;

Here's how you get the image size from the given URL in Python 3:

from PIL import Image
import urllib.request
from io import BytesIO

file = BytesIO(urllib.request.urlopen('http://getwallpapers.com/wallpaper/full/b/8/d/32803.jpg').read())
im = Image.open(file)
width, height = im.size

Suggest do this in your code-behind before sending down to SQL Server.

 int userVal = int.Parse(txtboxname.Text);

Perhaps try to parse and optionally let the user know.

int? userVal;
if (int.TryParse(txtboxname.Text, out userVal) 
{
  DoSomething(userVal.Value);
}
else
{ MessageBox.Show("Hey, we need an int over here.");   }

The exception you note means that you're not including the value in the call to the stored proc. Try setting a debugger breakpoint in your code at the time you call down into the code that builds the call to SQL Server.

Ensure you're actually attaching the parameter to the SqlCommand.

using (SqlConnection conn = new SqlConnection(connString))
{
    SqlCommand cmd = new SqlCommand(sql, conn);
    cmd.Parameters.Add("@ParamName", SqlDbType.Int);
    cmd.Parameters["@ParamName"].Value = newName;        
    conn.Open();
    string someReturn = (string)cmd.ExecuteScalar();        
}

Perhaps fire up SQL Profiler on your database to inspect the SQL statement being sent/executed.

There is two way to do this

1. Command line
2. Using python program

If you are using command line use python -m compileall <argument> to compile python code to python binary code. Ex: python -m compileall -x ./*

Or, You can use this code to compile your library into byte-code.

import compileall
import os

lib_path = "your_lib_path"
build_path = "your-dest_path"

compileall.compile_dir(lib_path, force=True, legacy=True)

def moveToNewLocation(cu_path):
    for file in os.listdir(cu_path):
        if os.path.isdir(os.path.join(cu_path, file)):
            compile(os.path.join(cu_path, file))
        elif file.endswith(".pyc"):
            dest = os.path.join(build_path, cu_path ,file)
            os.makedirs(os.path.dirname(dest), exist_ok=True)
            os.rename(os.path.join(cu_path, file), dest)

moveToNewLocation(lib_path)

From the command prompt, start up sqlcmd:

sqlcmd -S <server> -i C:\<your file here>.sql 

Just replace <server> with the location of your SQL box and <your file here> with the name of your script. Don't forget, if you're using a SQL instance the syntax is:

sqlcmd -S <server>\instance.

Here is the list of all arguments you can pass sqlcmd:

Sqlcmd            [-U login id]          [-P password]
  [-S server]            [-H hostname]          [-E trusted connection]
  [-d use database name] [-l login timeout]     [-t query timeout] 
  [-h headers]           [-s colseparator]      [-w screen width]
  [-a packetsize]        [-e echo input]        [-I Enable Quoted Identifiers]
  [-c cmdend]            [-L[c] list servers[clean output]]
  [-q "cmdline query"]   [-Q "cmdline query" and exit] 
  [-m errorlevel]        [-V severitylevel]     [-W remove trailing spaces]
  [-u unicode output]    [-r[0|1] msgs to stderr]
  [-i inputfile]         [-o outputfile]        [-z new password]
  [-f  | i:[,o:]] [-Z new password and exit] 
  [-k[1|2] remove[replace] control characters]
  [-y variable length type display width]

Already some great answers.But i would like to share anther idea which has proven to be reliable in comparing arrays. We can compare two array using JSON.stringify ( ) . It will create a string out the the array and thus compare two obtained strings from two array for equality

JSON.stringify([1,{a:1},2]) == JSON.stringify([1,{a:1},2]) //true

JSON.stringify([1,{a:1},2]) == JSON.stringify([1,{a:2},2]) //false

JSON.stringify([1,{a:1},2]) == JSON.stringify([1,{a:2},[3,4],2]) //false

JSON.stringify([1,{a:1},[3,4],2]) == JSON.stringify([1,{a:2},[3,4],2]) //false

JSON.stringify([1,{a:2},[3,4],2]) == JSON.stringify([1,{a:2},[3,4],2]) //true

JSON.stringify([1,{a:2},[3,4],2]) == JSON.stringify([1,{a:2},[3,4,[5]],2]) //false

JSON.stringify([1,{a:2},[3,4,[4]],2]) == JSON.stringify([1,{a:2},[3,4,[5]],2]) //false

JSON.stringify([1,{a:2},[3,4,[5]],2]) == JSON.stringify([1,{a:2},[3,4,[5]],2]) //true

pdf2htmlEX by coolwanglu is probably the best solution out there to convert a pdf file into html. You could do a simple convert and then embed the html page as an iframe or something similar.

There are a few efficient ways to implement this. Let's start with required imports:

from pyspark.sql.functions import col, expr, when

You can use Hive IF function inside expr:

new_column_1 = expr(
    """IF(fruit1 IS NULL OR fruit2 IS NULL, 3, IF(fruit1 = fruit2, 1, 0))"""
)

or when + otherwise:

new_column_2 = when(
    col("fruit1").isNull() | col("fruit2").isNull(), 3
).when(col("fruit1") == col("fruit2"), 1).otherwise(0)

Finally you could use following trick:

from pyspark.sql.functions import coalesce, lit

new_column_3 = coalesce((col("fruit1") == col("fruit2")).cast("int"), lit(3))

With example data:

df = sc.parallelize([
    ("orange", "apple"), ("kiwi", None), (None, "banana"), 
    ("mango", "mango"), (None, None)
]).toDF(["fruit1", "fruit2"])

you can use this as follows:

(df
    .withColumn("new_column_1", new_column_1)
    .withColumn("new_column_2", new_column_2)
    .withColumn("new_column_3", new_column_3))

and the result is:

+------+------+------------+------------+------------+
|fruit1|fruit2|new_column_1|new_column_2|new_column_3|
+------+------+------------+------------+------------+
|orange| apple|           0|           0|           0|
|  kiwi|  null|           3|           3|           3|
|  null|banana|           3|           3|           3|
| mango| mango|           1|           1|           1|
|  null|  null|           3|           3|           3|
+------+------+------------+------------+------------+

INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).

You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).

To Store "Country + area + number separately". You can try using a VARCHAR(20), this allows you the ability to store international phone numbers properly, should that need arise.

The problem is not that you can't forward-declare a template class. Yes, you do need to know all of the template parameters and their defaults to be able to forward-declare it correctly:

namespace std {
  template<class T, class Allocator = std::allocator<T>>
  class list;
}

But to make even such a forward declaration in namespace std is explicitly prohibited by the standard: the only thing you're allowed to put in std is a template specialisation, commonly std::less on a user-defined type. Someone else can cite the relevant text if necessary.

Just #include <list> and don't worry about it.

Oh, incidentally, any name containing double-underscores is reserved for use by the implementation, so you should use something like TEST_H instead of __TEST__. It's not going to generate a warning or an error, but if your program has a clash with an implementation-defined identifier, then it's not guaranteed to compile or run correctly: it's ill-formed. Also prohibited are names beginning with an underscore followed by a capital letter, among others. In general, don't start things with underscores unless you know what magic you're dealing with.

After updating my iPhone to 10.3.3, Xcode 8.3.3 cannot find it in the Device window but iTunes can. Restarting Xcode fixed the problem.

It seems that you are right. No option scales the image better:
http://www.maxrev.de/html/image-scaling.html

I've tested FF14, IE9, OP12 and GC21. Only GC has a better scaling that can be deactivated through image-rendering: -webkit-optimize-contrast. All other browsers have no/poor scaling.

Screenshot of the different output: http://www.maxrev.de/files/2012/08/screenshot_interpolation_jquery_animate.png

Update 2017

Meanwhile some more browsers support smooth scaling:

• ME38 (Microsoft Edge) has good scaling. It can't be disabled and it works for JPEG and PNG, but not for GIF.

• FF51 (Regarding @karthik 's comment since FF21) has good scaling that can be disabled through the following settings:

  image-rendering: optimizeQuality
  image-rendering: optimizeSpeed
  image-rendering: -moz-crisp-edges
  

  Note: Regarding MDN the optimizeQuality setting is a synonym for auto (but auto does not disable smooth scaling):

  The values optimizeQuality and optimizeSpeed present in early draft (and coming from its SVG counterpart) are defined as synonyms for the auto value.

• OP43 behaves like GC (not suprising as it is based on Chromium since 2013) and its still this option that disables smooth scaling:

  image-rendering: -webkit-optimize-contrast
  

No support in IE9-IE11. The -ms-interpolation-mode setting worked only in IE6-IE8, but was removed in IE9.

P.S. Smooth scaling is done by default. This means no image-rendering option is needed!

If wont work in case you have something like : novalidate="novalidate" attached to your form.

routes.MapRoute(
                "Area",
                "{area}/",
                new { area = "AreaZ", controller = "ControlerX ", action = "ActionY " }
            );

Have you tried that ?

You do not need the line:

import { SigninComponent, RegisterComponent } from './auth/auth.module';

in your app.component.ts as you already included the AuthModule in your app.module.ts. AutModule import is sufficient to use your component in the app.

The error that you get is a TypeScript error, not a Angular one, and it is correct in stating that there is no exported member, as it searches for a valid EC6 syntax for export, not angular module export. This line would thus work in your app.component.ts:

import { SigninComponent } from './auth/components/signin.component';
