For those who couldn't get choose007's answer up and running

If clickListener is not working properly at all times in chose007's solution, try to implement View.onTouchListener instead of clickListener. Handle touch event using any of the action ACTION_UP or ACTION_DOWN. For some reason, maps infoWindow causes some weird behaviour when dispatching to clickListeners.

infoWindow.findViewById(R.id.my_view).setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
          int action = MotionEventCompat.getActionMasked(event);
          switch (action){
                case MotionEvent.ACTION_UP:
                    Log.d(TAG,"a view in info window clicked" );
                    break;
                }
                return true;
          }

Edit : This is how I did it step by step

First inflate your own infowindow (global variable) somewhere in your activity/fragment. Mine is within fragment. Also insure that root view in your infowindow layout is linearlayout (for some reason relativelayout was taking full width of screen in infowindow)

infoWindow = (ViewGroup) getActivity().getLayoutInflater().inflate(R.layout.info_window, null);
/* Other global variables used in below code*/
private HashMap<Marker,YourData> mMarkerYourDataHashMap = new HashMap<>();
private GoogleMap mMap;
private MapWrapperLayout mapWrapperLayout;

Then in onMapReady callback of google maps android api (follow this if you donot know what onMapReady is Maps > Documentation - Getting Started )

   @Override
    public void onMapReady(GoogleMap googleMap) {
       /*mMap is global GoogleMap variable in activity/fragment*/
        mMap = googleMap;
       /*Some function to set map UI settings*/ 
        setYourMapSettings();

MapWrapperLayout initialization http://stackoverflow.com/questions/14123243/google-maps-android-api-v2- interactive-infowindow-like-in-original-android-go/15040761#15040761 39 - default marker height 20 - offset between the default InfoWindow bottom edge and it's content bottom edge */

        mapWrapperLayout.init(mMap, Utils.getPixelsFromDp(mContext, 39 + 20));

        /*handle marker clicks separately - not necessary*/
       mMap.setOnMarkerClickListener(this);

       mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
                @Override
                public View getInfoWindow(Marker marker) {
                    return null;
                }

            @Override
            public View getInfoContents(Marker marker) {
                YourData data = mMarkerYourDataHashMap.get(marker);
                setInfoWindow(marker,data);
                mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
                return infoWindow;
            }
        });
    }

SetInfoWindow method

private void setInfoWindow (final Marker marker, YourData data)
            throws NullPointerException{
        if (data.getVehicleNumber()!=null) {
            ((TextView) infoWindow.findViewById(R.id.VehicelNo))
                    .setText(data.getDeviceId().toString());
        }
        if (data.getSpeed()!=null) {
            ((TextView) infoWindow.findViewById(R.id.txtSpeed))
                    .setText(data.getSpeed());
        }

        //handle dispatched touch event for view click
        infoWindow.findViewById(R.id.any_view).setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int action = MotionEventCompat.getActionMasked(event);
                switch (action) {
                    case MotionEvent.ACTION_UP:
                        Log.d(TAG,"any_view clicked" );
                        break;
                }
                return true;
            }
        });

Handle marker click separately

    @Override
    public boolean onMarkerClick(Marker marker) {
        Log.d(TAG,"on Marker Click called");
        marker.showInfoWindow();
        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(marker.getPosition())      // Sets the center of the map to Mountain View
                .zoom(10)
                .build();
        mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition),1000,null);
        return true;
    }

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

If you also want to bind closing of infowindow to some event, try something like this

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
        windows.push(infowindow)
        google.maps.event.addListener(map,'click', function(){ 
            infowindow.close();
        }); 
    };
})(marker,content,infowindow)); 

I'm not aware of a tool that does this well but I've seen a variety of homegrown solutions. The common thread of these is to minimise the binary data under version control and maximise textual data to leverage the power of conventional scc systems. To do this:

• Treat the workbook like any other application. Seperate logic, config and data.
• Separate code from the workbook.
• Build the UI programmatically.
• Write a build script to reconstruct the workbook.

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

First error is caused by php because the extension mbstring is either not installed or not active.

The second error is output of phpMyAdmin/your site asking you to install / enable the mysqli extension.

To enable mbstring and mysqli edit your php.ini and add/uncomment the two lines with mbstring.so and mysqli.so on unix or mbstring.dll and mysqli.dll on windows

Unix /etc/(phpX/)php.ini

extension=mysqli.so
extension=mbstring.so

Windows PHP installation folder\etc\php.ini

extension=mysqli.dll
extension=mbstring.dll

Don't forget to restart your webserver after this.

EDIT: User added he was using redhat in the comments so here's how you install extensions on all CentOS/Fedora/RedHat/Yum based linux distros

sudo yum install php-mysqli
sudo yum install php-mbstring

restart your werbserver
sudo /etc/init.d/httpd restart

you can verify your installation with a little php script in your document root. This lists all settings, versions and active extensions you've installed for php

test.php

<?php
phpinfo();

I found an answer as I had the same issue today which is a 31st. It's not a bug in php as some would suggest, but is the expected functionality (in some since). According to this post what strtotime actually does is set the month back by one and does not modify the number of days. So in the event of today, May 31st, it's looking for April-31st which is an invalid date. So it then takes April 30 an then adds 1 day past it and yields May 1st.

In your example 2011-03-30, it would go back one month to February 30th, which is invalid since February only has 28 days. It then takes difference of those days (30-28 = 2) and then moves two days past February 28th which is March 2nd.

As others have pointed out, the best way to get "last month" is to add in either "first day of" or "last day of" using either strtotime or the DateTime object:

// Today being 2012-05-31
//All the following return 2012-04-30
echo date('Y-m-d', strtotime("last day of -1 month"));
echo date('Y-m-d', strtotime("last day of last month"));
echo date_create("last day of -1 month")->format('Y-m-d'); 

// All the following return 2012-04-01
echo date('Y-m-d', strtotime("first day of -1 month")); 
echo date('Y-m-d', strtotime("first day of last month"));
echo date_create("first day of -1 month")->format('Y-m-d');

So using these it's possible to create a date range if your making a query etc.

char* and char[] are different types, but it's not immediately apparent in all cases. This is because arrays decay into pointers, meaning that if an expression of type char[] is provided where one of type char* is expected, the compiler automatically converts the array into a pointer to its first element.

Your example function printSomething expects a pointer, so if you try to pass an array to it like this:

char s[10] = "hello";
printSomething(s);

The compiler pretends that you wrote this:

char s[10] = "hello";
printSomething(&s[0]);

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

<my-component :key="uniqueKey" />

along with it use this.$set(obj,'obj_key',value) and update uniqueKey for every update in object (obj) value for every update this.uniqueKey++

it worked for me this way

In SQL SERVER it is BIT, though it allows NULL to be stored

ALTER TABLE person add  [AdminApproved] BIT default 'FALSE';

Also there are other mistakes in your query

1. When you alter a table to add column no need to mention column keyword in alter statement

2. For adding default constraint no need to use SET keyword

3. Default value for a BIT column can be ('TRUE' or '1') / ('FALSE' or 0). TRUE or FALSE needs to mentioned as string not as Identifier

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

I also experienced the same error, "NPM package not installed correctly", while creating a Node.js project in Visual Studio 2015.

I resolved my issue by performing two steps:

1. Delete all files present in this location:

   C:\Users\<Your User Name>\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
   

   Restart Visual Studio.

2. Open Visual Studio and go to menu Tools ? NuGet Package Manager ? Package Manager Settings ?

   On the left side: You will see a drop down list: select Node.js, Tools ? Npm ? ClearCache ? *OK

Then again try to create the project. It resolved my issue.

I have tried this and it worked:

define PROPp_START_DT = TO_DATE('01-SEP-1999')

select * from proposal where prop_start_dt = &PROPp_START_DT

According to the ALTER DATABASE SET documentation, there is still a possibility that after setting a database to SINGLE_USER mode you won't be able to access that database:

Before you set the database to SINGLE_USER, verify the AUTO_UPDATE_STATISTICS_ASYNC option is set to OFF. When set to ON, the background thread used to update statistics takes a connection against the database, and you will be unable to access the database in single-user mode.

So, a complete script to drop the database with existing connections may look like this:

DECLARE @dbId int
DECLARE @isStatAsyncOn bit
DECLARE @jobId int
DECLARE @sqlString nvarchar(500)

SELECT @dbId = database_id,
       @isStatAsyncOn = is_auto_update_stats_async_on
FROM sys.databases
WHERE name = 'db_name'

IF @isStatAsyncOn = 1
BEGIN
    ALTER DATABASE [db_name] SET  AUTO_UPDATE_STATISTICS_ASYNC OFF

    -- kill running jobs
    DECLARE jobsCursor CURSOR FOR
    SELECT job_id
    FROM sys.dm_exec_background_job_queue
    WHERE database_id = @dbId

    OPEN jobsCursor

    FETCH NEXT FROM jobsCursor INTO @jobId
    WHILE @@FETCH_STATUS = 0
    BEGIN
        set @sqlString = 'KILL STATS JOB ' + STR(@jobId)
        EXECUTE sp_executesql @sqlString
        FETCH NEXT FROM jobsCursor INTO @jobId
    END

    CLOSE jobsCursor
    DEALLOCATE jobsCursor
END

ALTER DATABASE [db_name] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE

DROP DATABASE [db_name]

You can read the innerHTML attribute to get the source of the content of the element or outerHTML for the source with the current element.

Python:

element.get_attribute('innerHTML')

Java:

elem.getAttribute("innerHTML");

C#:

element.GetAttribute("innerHTML");

Ruby:

element.attribute("innerHTML")

JavaScript:

element.getAttribute('innerHTML');

PHP:

$element->getAttribute('innerHTML');

It was tested and worked with the ChromeDriver.

I know this question is pretty old, but figured I'd share some demo code this question helped me with.

• Create a Form with a Button and a DataGridView

                //c.ValueType = typeof(int);

                //Result is the same A or B
                dataGridView1[m_choiceCol, i] = c;

        }

        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 && e.RowIndex >= 0)
            {
                if (dataGridView1.CurrentCell.ColumnIndex == dataGridView1.Columns.IndexOf(dataGridView1.Columns[m_choiceCol]))
                {
                    DataGridViewCell cell = dataGridView1[m_choiceCol, e.RowIndex];

Note that the column index numbers can change from multiple button presses of button one, so I always refer to the columns by name not index value. I needed to incorporate David Hall's answer into my demo that already had ComboBoxes so his answer worked really well.

Rather than using direct tags, you can edit the css attribute for the color so that any tables you make will have the same color header text.

thead {
    color: #FFFFFF;
}

Try to run Your XAMPP Control Panel as Run as administrator, then install Apache and MySQL.

When XAMPP opens, ensure that Apache and MySQL services are stopped.

Now just check/tick on Apache and Mysql service module.

Now Apache and MySQL will be added to window services. You can set these services to start when Windows boots.

I have started using Gcfg which uses Ini-like files. It's simple - if you want something simple, this is a good choice.

Here's the loading code I am using currently, which has default settings and allows command line flags (not shown) that override some of my config:

package util

import (
    "code.google.com/p/gcfg"
)

type Config struct {
    Port int
    Verbose bool
    AccessLog string
    ErrorLog string
    DbDriver string
    DbConnection string
    DbTblPrefix string
}

type configFile struct {
    Server Config
}

const defaultConfig = `
    [server]
    port = 8000
    verbose = false
    accessLog = -
    errorLog  = -
    dbDriver     = mysql
    dbConnection = testuser:TestPasswd9@/test
    dbTblPrefix  =
`

func LoadConfiguration(cfgFile string, port int, verbose bool) Config {
    var err error
    var cfg configFile

    if cfgFile != "" {
        err = gcfg.ReadFileInto(&cfg, cfgFile)
    } else {
        err = gcfg.ReadStringInto(&cfg, defaultConfig)
    }

    PanicOnError(err)

    if port != 0 {
        cfg.Server.Port = port
    }
    if verbose {
        cfg.Server.Verbose = true
    }

    return cfg.Server
}

You can also use blank single quotes for the auto_increment column. something like this. It worked for me.

$query = "INSERT INTO myTable VALUES ('','Fname', 'Lname', 'Website')";

You have to install a Selenium Server (a Hub) and register your remote WebDriver to it. Then, your client will talk to the Hub which will find a matching WebDriver to execute your test.

You can have a look at here for more information.

Bash 4+ examples. Note: not using quotes will cause issues when words contain spaces, etc. Always quote in Bash, IMO.

Here are some examples Bash 4+:

Example 1, check for 'yes' in string (case insensitive):

    if [[ "${str,,}" == *"yes"* ]] ;then

Example 2, check for 'yes' in string (case insensitive):

    if [[ "$(echo "$str" | tr '[:upper:]' '[:lower:]')" == *"yes"* ]] ;then

Example 3, check for 'yes' in string (case sensitive):

     if [[ "${str}" == *"yes"* ]] ;then

Example 4, check for 'yes' in string (case sensitive):

     if [[ "${str}" =~ "yes" ]] ;then

Example 5, exact match (case sensitive):

     if [[ "${str}" == "yes" ]] ;then

Example 6, exact match (case insensitive):

     if [[ "${str,,}" == "yes" ]] ;then

Example 7, exact match:

     if [ "$a" = "$b" ] ;then

Example 8, wildcard match .ext (case insensitive):

     if echo "$a" | egrep -iq "\.(mp[3-4]|txt|css|jpg|png)" ; then

Enjoy.

For Linux let me introduce a shell script that will show the mac address and allows to change it (MAC sniffing).

 ifconfig eth0 | grep HWaddr |cut -dH -f2|cut -d\  -f2
 00:26:6c:df:c3:95

Cut arguements may dffer (I am not an expert) try:

ifconfig etho | grep HWaddr
eth0      Link encap:Ethernet  HWaddr 00:26:6c:df:c3:95  

To change MAC we may do:

ifconfig eth0 down
ifconfig eth0 hw ether 00:80:48:BA:d1:30
ifconfig eth0 up

will change mac address to 00:80:48:BA:d1:30 (temporarily, will restore to actual one upon reboot).

Format

Here is the format of the Dockerfile:

We can use # for commenting purpose#Comment for example

#FROM microsoft/aspnetcore
FROM microsoft/dotnet
COPY /publish /app
WORKDIR /app
ENTRYPOINT ["dotnet", "WebApp.dll"]

From the above file when we build the docker, it skips the first line and goes to the next line because we have commented it using #

Take a look there : http://developer.android.com/guide/topics/intents/intents-filters.html

DO you have update your manifest file in order to give call rights ?

@Override
public void onListItemClick(ListView l, View v, int pos, long id) {
    super.onListItemClick(l, v, pos, id);
    UserResult nextFrag= new UserResult();
    this.getFragmentManager().beginTransaction()
    .replace(R.id.content_frame, nextFrag, null)
    .addToBackStack(null)
    .commit();  
}

Please be carefull with the usage of autoSizeColumn(). It can be used without problems on small files but please take care that the method is called only once (at the end) for each column and not called inside a loop which would make no sense.

Please avoid using autoSizeColumn() on large Excel files. The method generates a performance problem.

We used it on a 110k rows/11 columns file. The method took ~6m to autosize all columns.

For more details have a look at: How to speed up autosizing columns in apache POI?

To get a timestamp from Date(), you'll need to divide getTime() by 1000, i.e. :

Date currentDate = new Date();
currentDate.getTime() / 1000;
// 1397132691

or simply:

long unixTime = System.currentTimeMillis() / 1000L;

For who are in rush for test execution, I had to use VS 2017 test explorer to run tests;

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

Check your namespaces. I had and issue with that. I found that out by adding another web service to the project to dup it like you did yours and noticed the namespace was different. I had renamed it at the beginning of the project and it looks like its persisted.

Advantage: This solution is irrespective of the source datatype (float, scientific, varchar, date etc)

String is limited to 10 digits, bigInt gets rid of decimal values

Mustache templates are, by design, very simple; the homepage even says:

Logic-less templates.

So the general approach is to do your logic in JavaScript and set a bunch of flags:

if(notified_type == "Friendship")
    data.type_friendship = true;
else if(notified_type == "Other" && action == "invite")
    data.type_other_invite = true;
//...

and then in your template:

{{#type_friendship}}
    friendship...
{{/type_friendship}}
{{#type_other_invite}}
    invite...
{{/type_other_invite}}

If you want some more advanced functionality but want to maintain most of Mustache's simplicity, you could look at Handlebars:

Handlebars provides the power necessary to let you build semantic templates effectively with no frustration.

Mustache templates are compatible with Handlebars, so you can take a Mustache template, import it into Handlebars, and start taking advantage of the extra Handlebars features.

Though you cannot convert an OutputStream to an InputStream, java provides a way using PipedOutputStream and PipedInputStream that you can have data written to a PipedOutputStream to become available through an associated PipedInputStream.
Sometime back I faced a similar situation when dealing with third party libraries that required an InputStream instance to be passed to them instead of an OutputStream instance.
The way I fixed this issue is to use the PipedInputStream and PipedOutputStream.
By the way they are tricky to use and you must use multithreading to achieve what you want. I recently published an implementation on github which you can use.
Here is the link . You can go through the wiki to understand how to use it.

Try YouCompleteMe. It uses Clang through the libclang interface, offering semantic C/C++/Objective-C completion. It's much like clang_complete, but substantially faster and with fuzzy-matching.

In addition to the above, YCM also provides semantic completion for C#, Python, Go, TypeScript etc. It also provides non-semantic, identifier-based completion for languages for which it doesn't have semantic support.

Open the hosts file located at : **C:\windows\system32\drivers\etc**.

Hosts file is for what?

Add the following at end of this file :

YourServerIP YourDNS

Example:

198.168.1.1 maps.google.com

To convert month number to month name, try the below

declare @month smallint = 1
select DateName(mm,DATEADD(mm,@month - 1,0))

No one has mentioned that

In default settings, Floats (System.Single) and doubles (System.Double) will never use overflow checking while Decimal (System.Decimal) will always use overflow checking.

I mean

decimal myNumber = decimal.MaxValue;
myNumber += 1;

throws OverflowException.

But these do not:

float myNumber = float.MaxValue;
myNumber += 1;

&

double myNumber = double.MaxValue;
myNumber += 1;

I think you should use some 3d party server to support the JWT token and there is no out of the box JWT support in WEB API 2.

However there is an OWIN project for supporting some format of signed token (not JWT). It works as a reduced OAuth protocol to provide just a simple form of authentication for a web site.

You can read more about it e.g. here.

It's rather long, but most parts are details with controllers and ASP.NET Identity that you might not need at all. Most important are

Step 9: Add support for OAuth Bearer Tokens Generation

Step 12: Testing the Back-end API

There you can read how to set up endpoint (e.g. "/token") that you can access from frontend (and details on the format of the request).

Other steps provide details on how to connect that endpoint to the database, etc. and you can chose the parts that you require.

htaccess files affect the directory they are placed in and all sub-directories, that is an htaccess file located in your root directory (yoursite.com) would affect yoursite.com/content, yoursite.com/content/contents, etc.

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

So you have committed your local changes to your local repository. Then in order to get remote changes to your local repository without making changes to your local files, you can use git fetch. Actually git pull is a two step operation: a non-destructive git fetch followed by a git merge. See What is the difference between 'git pull' and 'git fetch'? for more discussion.

Detailed example:

Suppose your repository is like this (you've made changes test2:

* ed0bcb2 - (HEAD, master) test2
* 4942854 - (origin/master, origin/HEAD) first

And the origin repository is like this (someone else has committed test1):

* 5437ca5 - (HEAD, master) test1
* 4942854 - first

At this point of time, git will complain and ask you to pull first if you try to push your test2 to remote repository. If you want to see what test1 is without modifying your local repository, run this:

$ git fetch

Your result local repository would be like this:

* ed0bcb2 - (HEAD, master) test2 
| * 5437ca5 - (origin/master, origin/HEAD) test1 
|/  
* 4942854 - first 

Now you have the remote changes in another branch, and you keep your local files intact.

Then what's next? You can do a git merge, which will be the same effect as git pull (when combined with the previous git fetch), or, as I would prefer, do a git rebase origin/master to apply your change on top of origin/master, which gives you a cleaner history.

You have to convert textbox's values to DateTime (t1,t2), then:

DateTime t1,t2;
t1 = DateTime.Parse(textbox1.Text);
t2 = DateTime.Parse(textbox2.Text);
int diff = ((TimeSpan)(t2 - t1)).TotalMilliseconds;

Or use DateTime.TryParse(textbox1, out t1); Error handling is up to you.

std::vector is a template class that encapsulate a dynamic array¹, stored in the heap, that grows and shrinks automatically if elements are added or removed. It provides all the hooks (begin(), end(), iterators, etc) that make it work fine with the rest of the STL. It also has several useful methods that let you perform operations that on a normal array would be cumbersome, like e.g. inserting elements in the middle of a vector (it handles all the work of moving the following elements behind the scenes).

Since it stores the elements in memory allocated on the heap, it has some overhead in respect to static arrays.

std::array is a template class that encapsulate a statically-sized array, stored inside the object itself, which means that, if you instantiate the class on the stack, the array itself will be on the stack. Its size has to be known at compile time (it's passed as a template parameter), and it cannot grow or shrink.

It's more limited than std::vector, but it's often more efficient, especially for small sizes, because in practice it's mostly a lightweight wrapper around a C-style array. However, it's more secure, since the implicit conversion to pointer is disabled, and it provides much of the STL-related functionality of std::vector and of the other containers, so you can use it easily with STL algorithms & co. Anyhow, for the very limitation of fixed size it's much less flexible than std::vector.

For an introduction to std::array, have a look at this article; for a quick introduction to std::vector and to the the operations that are possible on it, you may want to look at its documentation.

1. Actually, I think that in the standard they are described in terms of maximum complexity of the different operations (e.g. random access in constant time, iteration over all the elements in linear time, add and removal of elements at the end in constant amortized time, etc), but AFAIK there's no other method of fulfilling such requirements other than using a dynamic array. As stated by @Lucretiel, the standard actually requires that the elements are stored contiguously, so it is a dynamic array, stored where the associated allocator puts it.

You can use Array.ForEach()

Array.ForEach(employees, employee => {
   Array.ForEach(employee.Departments, department => department.SomeProperty = null);
   Collection.AddRange(employee.Departments);
});

With ASP.NET Web Pages you can do this on a single page as a basic GET example (the simplest possible thing that can work.

var json = Json.Encode(new {
    orientation = Cache["orientation"],
    alerted = Cache["alerted"] as bool?,
    since = Cache["since"] as DateTime?
});
Response.Write(json);

Short circuiting means the second operator will not be checked if the first operator decides the final outcome.

E.g. Expression is: True || False

In case of ||, all we need is one of the side to be True. So if the left hand side is true, there is no point in checking the right hand side, and hence that will not be checked at all.

Similarly, False && True

In case of &&, we need both sides to be True. So if the left hand side is False, there is no point in checking the right hand side, the answer has to be False. And hence that will not be checked at all.

You should use Merge: For example:

MERGE INTO employees e
    USING (SELECT * FROM hr_records WHERE start_date > ADD_MONTHS(SYSDATE, -1)) h
    ON (e.id = h.emp_id)
  WHEN MATCHED THEN
    UPDATE SET e.address = h.address
  WHEN NOT MATCHED THEN
    INSERT (id, address)
    VALUES (h.emp_id, h.address);

or

MERGE INTO employees e
    USING hr_records h
    ON (e.id = h.emp_id)
  WHEN MATCHED THEN
    UPDATE SET e.address = h.address
  WHEN NOT MATCHED THEN
    INSERT (id, address)
    VALUES (h.emp_id, h.address);

https://oracle-base.com/articles/9i/merge-statement

To pass info to a fragment , you setArguments when you create it, and you can retrieve this argument later on the method onCreate or onCreateView of your fragment.

On the newInstance function of your fragment you add the arguments you wanna send to it:

/**
 * Create a new instance of DetailsFragment, initialized to
 * show the text at 'index'.
 */
public static DetailsFragment newInstance(int index) {
    DetailsFragment f = new DetailsFragment();
    // Supply index input as an argument.
    Bundle args = new Bundle();
    args.putInt("index", index);
    f.setArguments(args);
    return f;
}

Then inside the fragment on the method onCreate or onCreateView you can retrieve the arguments like this:

Bundle args = getArguments();
int index = args.getInt("index", 0);

If you want now communicate from your fragment with your activity (sending or not data), you need to use interfaces. The way you can do this is explained really good in the documentation tutorial of communication between fragments. Because all fragments communicate between each other through the activity, in this tutorial you can see how you can send data from the actual fragment to his activity container to use this data on the activity or send it to another fragment that your activity contains.

Documentation tutorial:

http://developer.android.com/training/basics/fragments/communicating.html

In that way on windows pscp allows an upload directly (without any request for e.g. key-accepting):

How to update in codeignitor?

whenever you want to update same status with multiple rows you use where_in insteam of where or if you want to change only single record can use where.

below is my code

$conditionArray = array(1, 3, 4, 6);
$this->db->where_in("ip_id", $conditionArray);
$this->db->update($this->table, array("status" => 'active'));

its working perfect.

If you use Animator for make animation you can

anim (directory) -> fade_out.xml

<?xml version="1.0" encoding="UTF-8"?>
<objectAnimator
    android:propertyName="alpha"
    android:valueFrom="0"
    android:valueTo="1"
    xmlns:android="http://schemas.android.com/apk/res/android"/>

In java

Animator animator = AnimatorInflater.loadAnimator(context, R.animator.fade_out);
animator.setTarget(the_view_you_want_to_animation);
animator.setDuration(1000);
animator.start();

Other way to make animation fade out with only java code is

ObjectAnimator fadeOut = ObjectAnimator.ofFloat(the_view_you_want_to_animation, "alpha",  1f, 0);
fadeOut.setDuration(2000);
fadeOut.start();

First step you need add a row with key: View controller-based status bar appearance and value NO to Info.plist file. After that, add 2 functions in your controller to specific only that controller will effect:

override func viewWillAppear(_ animated: Bool) {
       super.viewWillAppear(animated)
       UIApplication.shared.statusBarStyle = .lightContent
}

override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        UIApplication.shared.statusBarStyle = .default    
}

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

Might be a pasting problem, but as far as I can see from your code, you're missing the single quotes around the HTML part you're echo-ing.

If not, could you post the code correctly and tell us what line is causing the error?

You can, once you escape the HTML correctly. This page shows what needs to be done.

If using PHP, you could use json_encode()

Hope this helps :)

For debugging mod_rewrite issues, you'll want to use RewriteLogLevel and RewriteLog:

RewriteLogLevel 3
RewriteLog "/usr/local/var/apache/logs/rewrite.log"

This variation of the query (as explained in other answers) worked for me.

RapidEXE is exactly for this job:

• SoftPedia page
  
• Author's original page

It converts a php project to a standalone exe. I had enough of all other compilers, tried them one by one and they all disappointed me one way or another. Be my guest, feedbacks are always welcome!

Side note: the mechanism behind it is quite similar to the WinRAR SFX approach; extract engine, extract source, then run. It's just faster and easier to work with. One-command compilation, compressed, smart unpack, auto cleanup, easy config, full control of php engine & version; also extensible with minimal effort.

Happy developing!

I had the same problems in two machines: Win8.1x64 with Visual Studio Ultimate 2013 (VS2013) and Win8x64 with VS2013 ultimate

Problem: Shortcut "VS2012 x86 Native Tools Command Prompt" which points to file: C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsall.bat which calls C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\vcvars32.bat tries to search the registry for value name "11.0":

reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "11.0"

However my machine doesn't have this value "11.0", instead it has "12.0"

My solution is to run C:\Program Files (x86)\ Microsoft Visual Studio 12.0 \VC\vcvarsall.bat which calls C:\Program Files (x86)\ Microsoft Visual Studio 12.0 \VC\bin\vcvars32.bat which correctly query the registry as the following:

reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "12.0"

So changing/running from C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsall.bat to C:\Program Files (x86)\ Microsoft Visual Studio 12.0 \VC\vcvarsall.bat solved it in my case

I'm particularly fond of this date picker built for Mootools: http://electricprism.com/aeron/calendar/

It's lovely right out of the box.

I've faced the exactly same problem but I've fixed it with another approache.

Using Ubuntu 18.04, first disable systemd-resolved service.

sudo systemctl disable systemd-resolved.service

Stop the service

sudo systemctl stop systemd-resolved.service

Then, remove the link to /run/systemd/resolve/stub-resolv.conf in /etc/resolv.conf

sudo rm /etc/resolv.conf

Add a manually created resolv.conf in /etc/

sudo vim /etc/resolv.conf

Add your prefered DNS server there

nameserver 208.67.222.222

I've tested this with success.

You can certainly us the a Select Agregation statement as Postulated by Ben James, However This will result in a view with as many columns as you have tables. An alternate method may be as follows:

SELECT COUNT(user_table.id) AS TableCount,'user_table' AS TableSource FROM user_table
UNION SELECT COUNT(cat_table.id) AS TableCount,'cat_table' AS TableSource FROM cat_table
UNION SELECT COUNT(course_table.id) AS TableCount, 'course_table' AS TableSource From course_table;

The Nice thing about an approch like this is that you can explicitly write the Union statements and generate a view or create a temp table to hold values that are added consecutively from a Proc cals using variables in place of your table names. I tend to go more with the latter, but it really depends on personal preference and application. If you are sure the tables will never change, you want the data in a single row format, and you will not be adding tables. stick with Ben James' solution. Otherwise I'd advise flexibility, you can always hack a cross tab struc.

Unless your click is firing some kind of ajax call to populate your list, you don't actually need to execute the click.

Just find the element and then enumerate the options, selecting the option(s) you want.

Here is an example:

from selenium import webdriver
b = webdriver.Firefox()
b.find_element_by_xpath("//select[@name='element_name']/option[text()='option_text']").click()

You can read more in:
https://sqa.stackexchange.com/questions/1355/unable-to-select-an-option-using-seleniums-python-webdriver

No, absolutely positioning does not conflict with flex containers. Making an element be a flex container only affects its inner layout model, that is, the way in which its contents are laid out. Positioning affects the element itself, and can alter its outer role for flow layout.

That means that

• If you add absolute positioning to an element with display: inline-flex, it will become block-level (like display: flex), but will still generate a flex formatting context.

• If you add absolute positioning to an element with display: flex, it will be sized using the shrink-to-fit algorithm (typical of inline-level containers) instead of the fill-available one.

That said, absolutely positioning conflicts with flex children.

As it is out-of-flow, an absolutely-positioned child of a flex container does not participate in flex layout.

Do you mean that require() is not resolved? You need to either add require.js to your project or enable Node.js Globals predefined library in Settings/Languages and Frameworks/JavaScript/Libraries.

(Edited settings path by @yurik)

In WebStorm 2016.x-2017.x: make sure that the Node.js Core library is enabled in Settings (Preferences) | Languages & Frameworks | Node.js and NPM

In IntelliJ 2018.3.2+ go to Settings (Preferences) | Languages & Frameworks | Node.js and NPM and enable Coding assistance for Node.js

It should work as expected. Try to run the following example.

Go with the mouse to the Windows Icon (lower left) and start typing "Anaconda". There should show up some matching entries. Select "Anaconda Prompt". A new command window, named "Anaconda Prompt" will open. Now, you can work from there with Python, conda and other tools.

I have not used pyserial but based on the API documentation at https://pyserial.readthedocs.io/en/latest/shortintro.html it seems like a very nice interface. It might be worth double-checking the specification for AT commands of the device/radio/whatever you are dealing with.

Specifically, some require some period of silence before and/or after the AT command for it to enter into command mode. I have encountered some which do not like reads of the response without some delay first.

This simple filtering can be achieved in many ways with Python. The best approach is to use "list comprehensions" as follows:

>>> lst = ['a', 'ab', 'abc', 'bac']
>>> [k for k in lst if 'ab' in k]
['ab', 'abc']

Another way is to use the filter function. In Python 2:

>>> filter(lambda k: 'ab' in k, lst)
['ab', 'abc']

In Python 3, it returns an iterator instead of a list, but you can cast it:

>>> list(filter(lambda k: 'ab' in k, lst))
['ab', 'abc']

Though it's better practice to use a comprehension.

From what I can gather layout_gravity is the gravity of that view inside its parent, and gravity is the gravity of the children inside that view.

I think this is right but the best way to find out is to play around.

Note: this answer is only valid for git v1.8 and older.

Most of this has been said in the other answers and comments, but here's a concise explanation:

• git fetch fetches all branch heads (or all specified by the remote.fetch config option), all commits necessary for them, and all tags which are reachable from these branches. In most cases, all tags are reachable in this way.
• git fetch --tags fetches all tags, all commits necessary for them. It will not update branch heads, even if they are reachable from the tags which were fetched.

Summary: If you really want to be totally up to date, using only fetch, you must do both.

It's also not "twice as slow" unless you mean in terms of typing on the command-line, in which case aliases solve your problem. There is essentially no overhead in making the two requests, since they are asking for different information.

An alternative would be simple js date() function, if you don't want to use jQuery/jQuery plugin:

e.g.:

var formattedDate = new Date("yourUnformattedOriginalDate");
var d = formattedDate.getDate();
var m =  formattedDate.getMonth();
m += 1;  // JavaScript months are 0-11
var y = formattedDate.getFullYear();

$("#txtDate").val(d + "." + m + "." + y);

see: 10 ways to format time and date using JavaScript

If you want to add leading zeros to day/month, this is a perfect example: Javascript add leading zeroes to date

and if you want to add time with leading zeros try this: getMinutes() 0-9 - how to with two numbers?

For MySQL 5.7.6 and later:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

For MySQL 5.7.5 and earlier:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

To select every nth element from any starting position in the vector

nth_element <- function(vector, starting_position, n) { 
  vector[seq(starting_position, length(vector), n)] 
  }

# E.g.
vec <- 1:12

nth_element(vec, 1, 3)
# [1]  1  4  7 10

nth_element(vec, 2, 3)
# [1]  2  5  8 11

I see potential shortcomings in many solutions posted above, so I decided to compile my own.
Note: it uses Array.prototype.some, check your browser support.

Solution below considers variable empty if one of the following is true:

1. JS thinks that variable is equal to false, which already covers many things like 0, "", [], and even [""] and [0]
2. Value is null or it's type is 'undefined'
3. It is an empty Object

4. It is an Object/Array consisting only of values that are empty themselves (i.e. broken down to primitives each part of it equals false). Checks drill recursively into Object/Array structure. E.g.

   isEmpty({"": 0}) // true
   isEmpty({"": 1}) // false
   isEmpty([{}, {}])  // true
   isEmpty(["", 0, {0: false}]) //true
   

Function code:

/**
 * Checks if value is empty. Deep-checks arrays and objects
 * Note: isEmpty([]) == true, isEmpty({}) == true, isEmpty([{0:false},"",0]) == true, isEmpty({0:1}) == false
 * @param value
 * @returns {boolean}
 */
function isEmpty(value){
  var isEmptyObject = function(a) {
    if (typeof a.length === 'undefined') { // it's an Object, not an Array
      var hasNonempty = Object.keys(a).some(function nonEmpty(element){
        return !isEmpty(a[element]);
      });
      return hasNonempty ? false : isEmptyObject(Object.keys(a));
    }

    return !a.some(function nonEmpty(element) { // check if array is really not empty as JS thinks
      return !isEmpty(element); // at least one element should be non-empty
    });
  };
  return (
    value == false
    || typeof value === 'undefined'
    || value == null
    || (typeof value === 'object' && isEmptyObject(value))
  );
}

You can create abstract classes by using object prototypes, a simple example can be as follows :

var SampleInterface = {
   addItem : function(item){}  
}

You can change above method or not, it is up to you when you implement it. For a detailed observation, you may want to visit here.

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.

JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.

JComponent - A base class for objects which intend to interact with Swing.

JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).

JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.

It seems that Google has updated its developer page and added various trainings there.

One of them deals with the creation of custom views and can be found here

If you want to maintain a folder and not the files inside it, just put a ".gitignore" file in the folder with "*" as the content. This file will make Git ignore all content from the repository. But .gitignore will be included in your repository.

$ git add path/to/folder/.gitignore

If you add an empty folder, you receive this message (.gitignore is a hidden file)

The following paths are ignored by one of your .gitignore files:
path/to/folder/.gitignore
Use -f if you really want to add them.
fatal: no files added

So, use "-f" to force add:

$ git add path/to/folder/.gitignore -f

This is valid YAML:

jobs:
 - name: A
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120
 - name: B
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120

Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.

return value is the normal value which is returned by your method.

Where as out parameter, well out and ref are 2 key words of C# they allow to pass variables as reference.

The big difference between ref and out is, ref should be initialised before and out don't

I'm no Git master, but from searching around the solution that worked easiest for me was to just go to C:\Program Files (x86)\Git\etc and open profile in a text editor.

There's an if statement on line 37 # Set up USER's home directory. I took out the if statement and put in the local directory that I wanted the gitconfig to be, then I just copied my existing gitconfig file (was on a network drive) to that location.

If dns_get_record() fails, it should return FALSE, so you can suppress the warning with @ and then check the return value.

If you can't be more specific than Object with your instances, then use:

List<Object> employees = new ArrayList<Object>();

Otherwise be as specific as you can:

List<? extends SpecificType> employees = new ArrayList<? extends SpecificType>();

Problem is that you are doing something wrong in XML layout file

android:text=" <- Go Back" // this creates error
android:text="Go Back" // correct way

You can add the command in the /etc/rc.local script that is executed at the end of startup.

Write the command before exit 0. Anything written after exit 0 will never be executed.

I had an issue with R 2.15.3 whereby while trying to create a tree structure recursively on a shared network drive I would get a permission error.

To get around this oddity I manually create the structure;

mkdirs <- function(fp) {
    if(!file.exists(fp)) {
        mkdirs(dirname(fp))
        dir.create(fp)
    }
} 

mkdirs("H:/foo/bar")

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

The difference between these two methods is:

• parseXxx() returns the primitive type
• valueOf() returns a wrapper object reference of the type.

Please do not mark this response as correct as smitec has already answered correctly. I'm including a convenience function I keep in my .First library that makes converting a windows path to the format that works in R (the methods described by Sacha Epskamp). Simply copy the path to your clipboard (ctrl + c) and then run the function as pathPrep(). No need for an argument. The path is printed to your console correctly and written to your clipboard for easy pasting to a script. Hope this is helpful.

pathPrep <- function(path = "clipboard") {
    y <- if (path == "clipboard") {
        readClipboard()
    } else {
        cat("Please enter the path:\n\n")
        readline()
    }
    x <- chartr("\\", "/", y)
    writeClipboard(x)
    return(x)
}

There is an amazing library called SwipeCellKit, it should gain more acknowledgement. In my opinion it is cooler than MGSwipeTableCell. The latter doesn't completely replicate the behavior of the Mail app's cells whereas SwipeCellKit does. Have a look

If this is your detail.html I don't see where do you load detail.js? Maybe this

<script src="js/index.js"></script>

should be this

<script src="js/detail.js"></script>

FOR SQLALCHEMY AND PYTHON

The encoding used for Unicode has traditionally been 'utf8'. However, for MySQL versions 5.5.3 on forward, a new MySQL-specific encoding 'utf8mb4' has been introduced, and as of MySQL 8.0 a warning is emitted by the server if plain utf8 is specified within any server-side directives, replaced with utf8mb3. The rationale for this new encoding is due to the fact that MySQL’s legacy utf-8 encoding only supports codepoints up to three bytes instead of four. Therefore, when communicating with a MySQL database that includes codepoints more than three bytes in size, this new charset is preferred, if supported by both the database as well as the client DBAPI, as in:

e = create_engine(
    "mysql+pymysql://scott:tiger@localhost/test?charset=utf8mb4")
All modern DBAPIs should support the utf8mb4 charset.

You're looking for tooltip

For the basic tooltip, you want:

<div title="This is my tooltip">

If you want to directly get the package name of the current app in focus, use this adb command -

adb shell dumpsys window windows | grep -E 'mFocusedApp'| cut -d / -f 1 | cut -d " " -f 7

Extra info from the result of the adb command is removed using the cut command. Original solution from here.

What worked for me in python 3.7 and img2pdf version 0.4.0 was to use something similar to the code given by Syed Shamikh Shabbir but changing the current working directory using OS as Stu suggested in his comment to Syed's solution

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

for image in images:
    with open(image[:-4] + ".pdf", "wb") as f:
        f.write(img2pdf.convert(image))

It is worth mentioning this solution above saves each .jpg separately in one single pdf. If you want all your .jpg files together in only one .pdf you could do:

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

with open("output.pdf", "wb") as f:
    f.write(img2pdf.convert(images))

If you need to save multiple objects, you can simply put them in a single list, or tuple, for instance:

import pickle

# obj0, obj1, obj2 are created here...

# Saving the objects:
with open('objs.pkl', 'w') as f:  # Python 3: open(..., 'wb')
    pickle.dump([obj0, obj1, obj2], f)

# Getting back the objects:
with open('objs.pkl') as f:  # Python 3: open(..., 'rb')
    obj0, obj1, obj2 = pickle.load(f)

If you have a lot of data, you can reduce the file size by passing protocol=-1 to dump(); pickle will then use the best available protocol instead of the default historical (and more backward-compatible) protocol. In this case, the file must be opened in binary mode (wb and rb, respectively).

The binary mode should also be used with Python 3, as its default protocol produces binary (i.e. non-text) data (writing mode 'wb' and reading mode 'rb').

You can use this code for copy input value in page in Clipboard by click a button

This is Html

<input type="text" value="xxx" id="link" class="span12" />
<button type="button" class="btn btn-info btn-sm" onclick="copyToClipboard('#link')">
    Copy Input Value
</button>

Then for this html , we must use this JQuery Code

function copyToClipboard(element) {
    $(element).select();
    document.execCommand("copy");
}

This is the simplest solution for this question

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

chris            930   0.0  3.1  2987336 258328 s000  S    Wed01PM   2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start

From the ps output, you can see both catalina.home and catalina.base. catalina.home is where the Tomcat base files are installed, and catalina.base is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.

You can also interrogate the JVM directly if you can't find it in a ps listing:

$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29

If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home and catalina.base.

I had this problem too and couldn't solve it without using VBA.

In my case I had a table with numbers that I wanted to be formatted and a corresponding table next to it with the desired formatting values.

i.e. While column F contains the values I want to format, the desired formatting for each cell is captured in column Z, expressed as "RED", "AMBER" or "GREEN."

Quick solution below. Manually select the range to which to apply the conditional formatting and then run the macro.

   Sub ConditionalFormatting()
For Each Cell In Selection.Cells
With Cell
    'clean
    .FormatConditions.Delete

    'green rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""GREEN"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .Color = -11489280
        .TintAndShade = 0
    End With
    .FormatConditions(1).StopIfTrue = False

    'amber rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""AMBER"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .ThemeColor = xlThemeColorAccent6
        .TintAndShade = -0.249946592608417
    End With
    .FormatConditions(1).StopIfTrue = False

    'red rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""RED"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .Color = -16776961
        .TintAndShade = 0
    End With
    .FormatConditions(1).StopIfTrue = False
End With

Next Cell

End Sub

You can make a text align to the right inside of any element, including labels.

Html:

<label>Text</label>

Css:

label {display:block; width:x; height:y; text-align:right;}

This way, you give a width and height to your label and make any text inside of it align to the right.

I know this is a old question but i think i must provide my answer to it because my problem was not solved by others.

first of all : i was dynamically adding fragments using fragmentTransactions. Second: my fragments were modified using AsyncTasks (DB queries on a server). Third: my fragment was not instantiated at activity start Fourth: i used a custom fragment instantiation "create or load it" in order to get the fragment variable. Fourth: activity was recreated because of orientation change

The problem was that i wanted to "remove" the fragment because of the query answer, but the fragment was incorrectly created just before. I don't know why, probably because of the "commit" be done later, the fragment was not added yet when it was time to remove it. Therefore getActivity() was returning null.

Solution : 1)I had to check that i was correctly trying to find the first instance of the fragment before creating a new one 2)I had to put serRetainInstance(true) on that fragment in order to keep it through orientation change (no backstack needed therefore no problem) 3)Instead of "recreating or getting old fragment" just before "remove it", I directly put the fragment at activity start. Instantiating it at activity start instead of "loading" (or instantiating) the fragment variable before removing it prevented getActivity problems.

The other way is to create Indexes for your collection and make sure that they are unique.

You can find more on the following link

I actually find this pretty simple and easy to implement.

I had the same problem cause i had no public keys, so i did:

heroku keys:clear
heroku keys:add

That will generate a public key and then it works well

For performance, especially when you're iterating over a large range, xrange() is usually better. However, there are still a few cases why you might prefer range():

• In python 3, range() does what xrange() used to do and xrange() does not exist. If you want to write code that will run on both Python 2 and Python 3, you can't use xrange().

• range() can actually be faster in some cases - eg. if iterating over the same sequence multiple times. xrange() has to reconstruct the integer object every time, but range() will have real integer objects. (It will always perform worse in terms of memory however)

• xrange() isn't usable in all cases where a real list is needed. For instance, it doesn't support slices, or any list methods.

[Edit] There are a couple of posts mentioning how range() will be upgraded by the 2to3 tool. For the record, here's the output of running the tool on some sample usages of range() and xrange()

RefactoringTool: Skipping implicit fixer: buffer

     d=(x for x in range(20))

As you can see, when used in a for loop or comprehension, or where already wrapped with list(), range is left unchanged.

Use the boolean() XPath function

The boolean function converts its argument to a boolean as follows:

• a number is true if and only if it is neither positive or negative zero nor NaN

• a node-set is true if and only if it is non-empty

• a string is true if and only if its length is non-zero

• an object of a type other than the four basic types is converted to a boolean in a way that is dependent on that type

If there is an AttachedXml in the CreditReport of primary Consumer, then it will return true().

boolean(/mc:Consumers
          /mc:Consumer[@subjectIdentifier='Primary']
            //mc:CreditReport/mc:AttachedXml)

I tried this solution with Microsoft.SqlServer.Management but it didn't work well with .NET 4.0 so I wrote another solution using .NET libs framework only.

string script = File.ReadAllText(@"E:\someSqlScript.sql");

// split script on GO command
IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$", RegexOptions.Multiline | RegexOptions.IgnoreCase);

Connection.Open();
foreach (string commandString in commandStrings)
{
    if (!string.IsNullOrWhiteSpace(commandString.Trim()))
    {
        using(var command = new SqlCommand(commandString, Connection))
        {
            command.ExecuteNonQuery();
        }
    }
}     
Connection.Close();

An even better/cleaner potential way than the answers proposed is to overwrite the accessor, like this:

def status
  self['status'] || ACTIVE
end

See "Overwriting default accessors" in the ActiveRecord::Base documentation and more from StackOverflow on using self.

/proc/partitions will list all the block devices and partitions that the system recognizes. You can then try using file -s <device> to determine what kind of filesystem is present on the partition, if any.

If someone is using bootstrap sass note the code is on the _reboot.scss file like this:

button:focus {
  outline: 1px dotted;
  outline: 5px auto -webkit-focus-ring-color;
}

So if you want to keep the _reboot file I guess feel free to override with plain css instead of trying to look for a variable to change.

You can try defining a constant in index.php and add something like

if (!defined("YOUR_CONSTANT")) die('No direct access');

to the beginning of the other files.

OR, you can use mod_rewrite and redirect requests to index.php, editing .htaccess like this:

RewriteEngine on
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L,R=301]

Then you should be able to analyze all incoming requests in the index.php and take according actions.

If you want to leave out all *.jpg, *.gif, *.css and *.png files, for example, then you should edit second line like this:

RewriteCond $1 !^(index\.php|*\.jpg|*\.gif|*\.css|*\.png)

Many people have answered this correctly but here is another way which actually not only covers 1-99 but it actually goes above any data range but it does not cover decimals.

Note: this was tested using python 3.7

def convert(num):
    units = ("", "one ", "two ", "three ", "four ","five ", "six ", "seven ","eight ", "nine ", "ten ", "eleven ", "twelve ", "thirteen ", "fourteen ", "fifteen ","sixteen ", "seventeen ", "eighteen ", "nineteen ")
    tens =("", "", "twenty ", "thirty ", "forty ", "fifty ","sixty ","seventy ","eighty ","ninety ")

    if num < 0:
        return "minus "+convert(-num)

    if num<20:
        return  units[num] 

    if num<100:

        return  tens[num // 10]  +units[int(num % 10)] 

    if num<1000:
        return units[num // 100]  +"hundred " +convert(int(num % 100))

    if num<1000000: 
        return  convert(num // 1000) + "thousand " + convert(int(num % 1000))

    if num < 1000000000:    
        return convert(num // 1000000) + "million " + convert(int(num % 1000000))

    return convert(num // 1000000000)+ "billion "+ convert(int(num % 1000000000))


print(convert(100001333))

Use this line to get the division behavior you want:

from __future__ import division

Alternatively, you could use modulus:

if (a % b) == 0: #do something

I did it with jQuery:

page.execute_script %Q{ $('#some_id').prop('checked', true) }

For MS Access: Launch a hidden form with Me.TimerInterval set and a Form_Timer event handler. Put your to-be-delayed code in the Form_Timer routine - exiting the routine after each execution.

E.g.:

Private Sub Form_Load()
    Me.TimerInterval = 30000 ' 30 sec
End Sub

Private Sub Form_Timer()

    Dim lngTimerInterval  As Long: lngTimerInterval = Me.TimerInterval

    Me.TimerInterval = 0

    '<Your Code goes here>

    Me.TimerInterval = lngTimerInterval
End Sub

"Your Code goes here" will be executed 30 seconds after the form is opened and 30 seconds after each subsequent execution.

Close the hidden form when done.

Current date time to formated string:

let currentDate = Date()
let dateFormatter = DateFormatter()

dateFormatter.dateFormat = "dd/MM/yyyy hh:mm:ss a"
let convertedDate: String = dateFormatter.string(from: currentDate) //08/10/2016 01:42:22 AM

If you are using the latest version of Android studio. then you don't need to install additional software for Git other than GIT itself - https://git-scm.com/downloads

Steps

1. Create an account on Github - https://github.com/join
2. Install Git
3. Open your working project in Android studio
4. GoTo - File -> Settings -> Version Controll -> GitHub
5. Enter Login and Password which you have created just on Git Account and click on test
6. Once all credentials are true - it shows Success message. o.w Invalid Cred.
7. Now click on VCS in android studio menu bar
8. Select Import into Version Control -> Share Project on GitHub
9. The popup dialog will occure contains all your files with check mark, do ok or commit all
10. At next time whenever you want to push your project just click on VCS - > Commit Changes -> Commmit and Push.

That's it. You can find your project on your github now

Frames were not deprecated in HTML5, but were deprecated in XHTML 1.1 Strict and 2.0, but remained in XHTML Transitional and returned in HTML5. Also here is an interesting article on using CSS to mimic frames without frames. I just tested it in IE 8, FF 3, Opera 11, Safari 5, Chrome 8. I love frames, but they do have their problems, particularly with search engines, bookmarks and printing and with CSS you can create print or display only content. I'm hoping to upgrade Alex's XHTML/CSS frame without frames solution to HTML5/CSS3.

echo "echo "we are now going to work with ${ser}" " >> $servfile

Escape all " within quotes with \. Do this with variables like \$servicetest too:

echo "echo \"we are now going to work with \${ser}\" " >> $servfile    
echo "read -p \"Please enter a service: \" ser " >> $servfile
echo "if [ \$servicetest > /dev/null ];then " >> $servfile

With the help of the given links I was able to solve the problem myself. The correct way is to get the resource ID with

getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
                             "raw", getPackageName());

To get it as a InputStream

InputStream ins = getResources().openRawResource(
            getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
            "raw", getPackageName()));

A pure Bash way with no eval, no subshells, no external tools, no brace expansions (i.e., you can have the number to repeat in a variable):

If you're given a variable n that expands to a (non-negative) number and a variable pattern, e.g.,

$ n=5
$ pattern=hello
$ printf -v output '%*s' "$n"
$ output=${output// /$pattern}
$ echo "$output"
hellohellohellohellohello

You can make a function with this:

repeat() {
    # $1=number of patterns to repeat
    # $2=pattern
    # $3=output variable name
    local tmp
    printf -v tmp '%*s' "$1"
    printf -v "$3" '%s' "${tmp// /$2}"
}

With this set:

$ repeat 5 hello output
$ echo "$output"
hellohellohellohellohello

For this little trick we're using printf quite a lot with:

• -v varname: instead of printing to standard output, printf will put the content of the formatted string in variable varname.
• '%*s': printf will use the argument to print the corresponding number of spaces. E.g., printf '%*s' 42 will print 42 spaces.
• Finally, when we have the wanted number of spaces in our variable, we use a parameter expansion to replace all the spaces by our pattern: ${var// /$pattern} will expand to the expansion of var with all the spaces replaced by the expansion of $pattern.

You can also get rid of the tmp variable in the repeat function by using indirect expansion:

repeat() {
    # $1=number of patterns to repeat
    # $2=pattern
    # $3=output variable name
    printf -v "$3" '%*s' "$1"
    printf -v "$3" '%s' "${!3// /$2}"
}

You will have to use javascript, or the JQuery framework to do that. her is an example using Jquery

   $('#toggle').click(function () {
        //check if checkbox is checked
        if ($(this).is(':checked')) {

            $('#sendNewSms').removeAttr('disabled'); //enable input

        } else {
            $('#sendNewSms').attr('disabled', true); //disable input
        }
    });

I just wanted to use the import and export in JavaScript files.

Everyone says it's not possible. But, as of May 2018, it's possible to use above in plain Node.js, without any modules like Babel, etc.

Here is a simple way to do it.

Create the below files, run, and see the output for yourself.

Also don't forget to see Explanation below.

File myfile.mjs

function myFunc() {
    console.log("Hello from myFunc")
}

export default myFunc;

File index.mjs

import myFunc from "./myfile.mjs"  // Simply using "./myfile" may not work in all resolvers

myFunc();

Run

node  --experimental-modules  index.mjs

Output

(node:12020) ExperimentalWarning: The ESM module loader is experimental.

Hello from myFunc

Explanation:

1. Since it is experimental modules, .js files are named .mjs files
2. While running you will add --experimental-modules to the node index.mjs
3. While running with experimental modules in the output you will see: "(node:12020) ExperimentalWarning: The ESM module loader is experimental. "
4. I have the current release of Node.js, so if I run node --version, it gives me "v10.3.0", though the LTE/stable/recommended version is 8.11.2 LTS.
5. Someday in the future, you could use .js instead of .mjs, as the features become stable instead of Experimental.
6. More on experimental features, see: https://nodejs.org/api/esm.html

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

If you want to color your terminal console, then you can use npm package chalk

npm i chalk

It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.

To create a master branch:

git checkout -b master

And you can work off of that.

Converting to a list without using the keys method makes it more readable:

list(newdict)

and, when looping through dictionaries, there's no need for keys():

for key in newdict:
    print key

unless you are modifying it within the loop which would require a list of keys created beforehand:

for key in list(newdict):
    del newdict[key]

On Python 2 there is a marginal performance gain using keys().

SQLAlchemy upsert for Postgres >=9.5

Since the large post above covers many different SQL approaches for Postgres versions (not only non-9.5 as in the question), I would like to add how to do it in SQLAlchemy if you are using Postgres 9.5. Instead of implementing your own upsert, you can also use SQLAlchemy's functions (which were added in SQLAlchemy 1.1). Personally, I would recommend using these, if possible. Not only because of convenience, but also because it lets PostgreSQL handle any race conditions that might occur.

Cross-posting from another answer I gave yesterday (https://stackoverflow.com/a/44395983/2156909)

SQLAlchemy supports ON CONFLICT now with two methods on_conflict_do_update() and on_conflict_do_nothing():

Copying from the documentation:

from sqlalchemy.dialects.postgresql import insert

stmt = insert(my_table).values(user_email='[email protected]', data='inserted data')
stmt = stmt.on_conflict_do_update(
    index_elements=[my_table.c.user_email],
    index_where=my_table.c.user_email.like('%@gmail.com'),
    set_=dict(data=stmt.excluded.data)
    )
conn.execute(stmt)

http://docs.sqlalchemy.org/en/latest/dialects/postgresql.html?highlight=conflict#insert-on-conflict-upsert

May be by:-

    for(Row row : sheet) {          
        for(Cell cell : row) {              
            System.out.print(cell.getStringCellValue());

        }
    }       

For specific type of cell you can try:

switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
    cellValue = cell.getStringCellValue();
    break;

case Cell.CELL_TYPE_FORMULA:
    cellValue = cell.getCellFormula();
    break;

case Cell.CELL_TYPE_NUMERIC:
    if (DateUtil.isCellDateFormatted(cell)) {
        cellValue = cell.getDateCellValue().toString();
    } else {
        cellValue = Double.toString(cell.getNumericCellValue());
    }
    break;

case Cell.CELL_TYPE_BLANK:
    cellValue = "";
    break;

case Cell.CELL_TYPE_BOOLEAN:
    cellValue = Boolean.toString(cell.getBooleanCellValue());
    break;

}

The easiest way I have found to do it is like this:

dict_count = len(dict_list)
df = pd.DataFrame(dict_list[0], index=[0])
for i in range(1,dict_count-1):
    df = df.append(dict_list[i], ignore_index=True)

Edit: Harhar is now open source. I have updated the URL below.

If you use an Avalanche load generator, you can use Harhar to replay a HAR file at very high load: https://acastaner.github.io/harhar/

This tool handles the "content" you use when you "Save as HAR with content."

Do you want the server name? Or the host name?

Request.Url.Host ala Stephen

Dns.GetHostName - Server name

Request.Url will have access to most everything you'll need to know about the page being requested.

just fetch specific node data and its working perfect for me

mFirebaseInstance.getReference("yourNodeName").getRef().addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {


        for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
            Log.e(TAG, "======="+postSnapshot.child("email").getValue());
            Log.e(TAG, "======="+postSnapshot.child("name").getValue());
        }
    }

    @Override
    public void onCancelled(DatabaseError error) {
        // Failed to read value
        Log.e(TAG, "Failed to read app title value.", error.toException());
    }
});

The first example doesn't work because you can't assign values to arrays - arrays work (sort of) like const pointers in this respect. What you can do though is copy a new value into the array:

strcpy(p.name, "Jane");

Char arrays are fine to use if you know the maximum size of the string in advance, e.g. in the first example you are 100% sure that the name will fit into 19 characters (not 20 because one character is always needed to store the terminating zero value).

Conversely, pointers are better if you don't know the possible maximum size of your string, and/or you want to optimize your memory usage, e.g. avoid reserving 512 characters for the name "John". However, with pointers you need to dynamically allocate the buffer they point to, and free it when not needed anymore, to avoid memory leaks.

Update: example of dynamically allocated buffers (using the struct definition in your 2nd example):

char* firstName = "Johnnie";

Check out my highly simplified Echo example: It is designed to use basic HTTP communication, but it can easily be modified to use named pipes by editing the app.config files for the client and server. Make the following changes:

Edit the server's app.config file, removing or commenting out the http baseAddress entry and adding a new baseAddress entry for the named pipe (called net.pipe). Also, if you don't intend on using HTTP for a communication protocol, make sure the serviceMetadata and serviceDebug is either commented out or deleted:

<configuration>
    <system.serviceModel>
        <services>
            <service name="com.aschneider.examples.wcf.services.EchoService">
                <host>
                    <baseAddresses>
                        <add baseAddress="net.pipe://localhost/EchoService"/>
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors></serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

Edit the client's app.config file so that the basicHttpBinding is either commented out or deleted and a netNamedPipeBinding entry is added. You will also need to change the endpoint entry to use the pipe:

<configuration>
    <system.serviceModel>
        <bindings>
            <netNamedPipeBinding>
                <binding name="NetNamedPipeBinding_IEchoService"/>
            </netNamedPipeBinding>
        </bindings>
        <client>
            <endpoint address              = "net.pipe://localhost/EchoService"
                      binding              = "netNamedPipeBinding"
                      bindingConfiguration = "NetNamedPipeBinding_IEchoService"
                      contract             = "EchoServiceReference.IEchoService"
                      name                 = "NetNamedPipeBinding_IEchoService"/>
        </client>
    </system.serviceModel>
</configuration>

The above example will only run with named pipes, but nothing is stopping you from using multiple protocols to run your service. AFAIK, you should be able to have a server run a service using both named pipes and HTTP (as well as other protocols).

Also, the binding in the client's app.config file is highly simplified. There are many different parameters you can adjust, aside from just specifying the baseAddress...

For systemd style init scripts it's really easy. You just add a User= in the [Service] section.

Here is an init script I use for qbittorrent-nox on CentOS 7:

[Unit]
Description=qbittorrent torrent server

[Service]
User=<username>
ExecStart=/usr/bin/qbittorrent-nox
Restart=on-abort

[Install]
WantedBy=multi-user.target

I think this should also work:

function $_GET(q,s) {
    s = (s) ? s : window.location.search;
    var re = new RegExp('&'+q+'=([^&]*)','i');
    return (s=s.replace(/^\?/,'&').match(re)) ?s=s[1] :s='';
}

Just call it like this:

var value = $_GET('myvariable');

Other than adding and remove from the middle of the list, I like linked lists more because they can grow and shrink dynamically.

You would need to use the following markup. If you want to float any menu items to the right, create a separate <ul class="nav navbar-nav"> with navbar-right class to it.

You can use jade + express:

app.get('/', function (req, res) { res.render('index', { title : 'Home' } ) });

above you see 'index' and an object {title : 'Home'}, 'index' is your html and the object is your data that will be rendered in your html.

A very simple check you can do with Cell formulas:

Sheet 1 (new - old)

=(if(AND(Ref_New<>"";Ref_Old="");Ref_New;"")

Sheet 2 (old - new)

=(if(AND(Ref_Old<>"";Ref_New="");Ref_Old;"")

This formulas should work for an ENGLISH Excel. For other languages they need to be translated. (For German i can assist)

You need to open all three Excel Documents, then copy the first formula into A1 of your sheet 1 and the second into A1 of sheet 2. Now click in A1 of the first cell and mark "Ref_New", now you can select your reference, go to the new file and click in the A1, go back to sheet1 and do the same for "Ref_Old" with the old file. Replace also the other "Ref_New".

Doe the same for Sheet two.

Now copy the formaula form A1 over the complete range where zour data is in the old and the new file.

But two cases are not covered here:

1. In the compared cell of New and Old is the same data (Resulting Cell will be empty)
2. In the compared cell of New and Old is diffe data (Resulting Cell will be empty)

To cover this two cases also, you should create your own function, means learn VBA. A very useful Excel page is cpearson.com

I wrote the following method which works for me.

protected bool isDirectoryFound(string path, string pattern)
    {
        bool success = false;

        DirectoryInfo directories = new DirectoryInfo(@path);
        DirectoryInfo[] folderList = directories.GetDirectories();

        Regex rx = new Regex(pattern);

        foreach (DirectoryInfo di in folderList)
        {
            if (rx.IsMatch(di.Name))
            {
                success = true;
                break;
            }
        }

        return success;
    }

The lines most pertinent to your question being:

DirectoryInfo directories = new DirectoryInfo(@path); DirectoryInfo[] folderList = directories.GetDirectories();

Just use the URL() constructor:

new URL(url).host

As others have correctly pointed out, the first part of the ternary needs to return true or false and in your question the return value is a jQuery object.

The problem that you may have in the comparison is that the web color will be converted to RGB so you have to text for that in the ternary condition.

So with the CSS:

#blackbox {
    background:pink;
    width:10px;
    height:10px;
}

The following jQuery will flip the colour:

var b = $('#blackbox');
b.css('background', (b.css('backgroundColor') === 'rgb(255, 192, 203)' ? 'black' : 'pink'));

Take a look at the FormData object: https://developer.mozilla.org/en/docs/Web/API/FormData

this.uploadFileToUrl = function(file, uploadUrl){
        var fd = new FormData();
        fd.append('file', file);
        $http.post(uploadUrl, fd, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
        .success(function(){
        })
        .error(function(){
        });
    }

To save to a file on Windows, OSX and Linux

adb exec-out screencap -p > screen.png

To copy to clipboard on Linux use

adb exec-out screencap -p | xclip -t image/png

No, there's no standard way. I believe that the C/C++ standards don't even consider the existence of directories (or other file system organizations).

On Windows the GetModuleFileName() will return the full path to the executable file of the current process when the hModule parameter is set to NULL. I can't help with Linux.

Also you should clarify whether you want the current directory or the directory that the program image/executable resides. As it stands your question is a little ambiguous on this point.

Here is an example from my code (for threaded pool, but just change class name and you'll have process pool):

def execute_run(rp): 
   ... do something 

pool = ThreadPoolExecutor(6)
for mat in TESTED_MATERIAL:
    for en in TESTED_ENERGIES:
        for ecut in TESTED_E_CUT:
            rp = RunParams(
                simulations, DEST_DIR,
                PARTICLE, mat, 960, 0.125, ecut, en
            )
            pool.submit(execute_run, rp)
pool.join()

Basically:

• pool = ThreadPoolExecutor(6) creates a pool for 6 threads
• Then you have bunch of for's that add tasks to the pool
• pool.submit(execute_run, rp) adds a task to pool, first arogument is a function called in in a thread/process, rest of the arguments are passed to the called function.
• pool.join waits until all tasks are done.

Gustavomcls's solution to change com.google.* version to same version worked for me .

I change both dependancies to 9.2.1 in buid.gradle (Module:app)

compile 'com.google.firebase:firebase-ads:9.2.1'
compile 'com.google.android.gms:play-services:9.2.1'

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

Change to a Do loop instead:

Do While True
    count = count + 1

    If count = 10 Then
        Exit Do
    End If
Loop

Or for looping a set number of times:

for count = 1 to 10
   msgbox count
next

(Exit For can be used above to exit prematurely)

You may be forgetting something. Before #include <iostream>, write #include <stdafx.h> and maybe that will help. Then, when you are done writing, click test, than click output from build, then when it is done processing/compiling, press Ctrl+F5 to open the Command Prompt and it should have the output and "press any key to continue."

You may want to use async/await, since node v10.0.0 it's possible with the built-in fs Promises API.

Example:

const fs = require('fs')

const copyFile = async (src, dest) => {
  await fs.promises.copyFile(src, dest)
}

Note:

As of node v11.14.0, v10.17.0 the API is no longer experimental.

If you really don't care about which timestamp you'll get and your v_id is always the same for a given m_i you can do the following:

select m_id, v_id, max(timestamp) from table
group by m_id, v_id
order by timestamp desc

Now, if the v_id changes for a given m_id then you should do the following

select t1.* from table t1
left join table t2 on t1.m_id = t2.m_id and t1.timestamp < t2.timestamp
where t2.timestamp is null
order by t1.timestamp desc

Also make sure that you have allowed codeigniter to log the type of messages you want in a config file.

i.e $config['log_threshold'] = [log_level ranges 0-4];

#ios #swift #convertDateinString

Simply just do like this to "convert date into string" as per format you passed:

let formatter = DateFormatter()

formatter.dateFormat = "dd-MM-YYYY" // pass formate here
        
let myString = formatter.string(from: date) // this will convert Date in String

Note: You can specify different formats such like "yyyy-MM-dd", "yyyy", "MM" etc...

There's a new @config tag for these cases. They link to the preceding @param.

/** My function does X and Y.
    @params {object} parameters An object containing the parameters
    @config {integer} setting1 A required setting.
    @config {string} [setting2] An optional setting.
    @params {MyClass~FuncCallback} callback The callback function
*/
function(parameters, callback) {
    // ...
};

/**
 * This callback is displayed as part of the MyClass class.
 * @callback MyClass~FuncCallback
 * @param {number} responseCode
 * @param {string} responseMessage
 */

All DECLAREs need to be at the top. ie.

delimiter //

CREATE TRIGGER pgl_new_user 
AFTER INSERT ON users FOR EACH ROW
BEGIN
    DECLARE m_user_team_id integer;
    DECLARE m_projects_id integer;
    DECLARE cur CURSOR FOR SELECT project_id FROM user_team_project_relationships WHERE user_team_id = m_user_team_id;

    SET @m_user_team_id := (SELECT id FROM user_teams WHERE name = "pgl_reporters");

    OPEN cur;
        ins_loop: LOOP
            FETCH cur INTO m_projects_id;
            IF done THEN
                LEAVE ins_loop;
            END IF;
            INSERT INTO users_projects (user_id, project_id, created_at, updated_at, project_access)

Let's say there is an administrator dashboard where users are listed with their id printed as a data attribute so it can be retrieved at some point via JavaScript.

An update could be executed this way …

class UserRepository extends \Doctrine\ORM\EntityRepository
{
    public function updateUserStatus($userId, $newStatus)
    {
        return $this->createQueryBuilder('u')
            ->update()
            ->set('u.isActive', '?1')
            ->setParameter(1, $qb->expr()->literal($newStatus))
            ->where('u.id = ?2')
            ->setParameter(2, $qb->expr()->literal($userId))
            ->getQuery()
            ->getSingleScalarResult()
        ;
    }

AJAX action handling:

# Post datas may be:
# handled with a specific custom formType — OR — retrieved from request object
$userId = (int)$request->request->get('userId');
$newStatus = (int)$request->request->get('newStatus');
$em = $this->getDoctrine()->getManager();
$r = $em->getRepository('NAMESPACE\User')
        ->updateUserStatus($userId, $newStatus);
if ( !empty($r) ){
    # Row updated
}

For those not sure about which peak-finding algorithms to use in Python, here a rapid overview of the alternatives: https://github.com/MonsieurV/py-findpeaks

Wanting myself an equivalent to the MatLab findpeaks function, I've found that the detect_peaks function from Marcos Duarte is a good catch.

Pretty easy to use:

import numpy as np
from vector import vector, plot_peaks
from libs import detect_peaks
print('Detect peaks with minimum height and distance filters.')
indexes = detect_peaks.detect_peaks(vector, mph=7, mpd=2)
print('Peaks are: %s' % (indexes))

Which will give you:

What about a little trickery like NgModel does with NgForm? You have to register your parent as a provider, then load your parent in the constructor of the child.

That way, you don't have to put [sharedList] on all your children.

// Parent.ts
export var parentProvider = {
    provide: Parent,
    useExisting: forwardRef(function () { return Parent; })
};

@Component({
    moduleId: module.id,
    selector: 'parent',
    template: '<div><ng-content></ng-content></div>',
    providers: [parentProvider]
})
export class Parent {
    @Input()
    public sharedList = [];
}

// Child.ts
@Component({
    moduleId: module.id,
    selector: 'child',
    template: '<div>child</div>'
})
export class Child {
    constructor(private parent: Parent) {
        parent.sharedList.push('Me.');
    }
}

Then your HTML

<parent [sharedList]="myArray">
    <child></child>
    <child></child>
</parent>

You can find more information on the subject in the Angular documentation: https://angular.io/guide/dependency-injection-in-action#find-a-parent-component-by-injection

You could make two forms with 2 different actions

<form action="login.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<br />

<form action="register.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Register">
</form>

Or do this

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="login">
    <input type="submit" value="Login">
</form>

<br />

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="register">
    <input type="submit" value="Register">
</form>

Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.

Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure

Installation and Calling Phantomjs

Follow the steps doesn't work, but cloned from others built. (ver2.0)

An easy and usable way to solve this problem

getGetSuppor(filter): Observale<any[]> {
   return this.https.get<any[]>('/api/callCenter/getSupport' + '?' + this.toQueryString(filter));
}

private toQueryString(query): string {
   var parts = [];
   for (var property in query) {
     var value = query[propery];
     if (value != null && value != undefined)
        parts.push(encodeURIComponent(propery) + '=' + encodeURIComponent(value))
   }
   
   return parts.join('&');
}

Super simple answer - solved!

my full answer here it is now built in in some oracle versions.

select group_id, 
regexp_replace(
    listagg(name, ',') within group (order by name)
    ,'([^,]+)(,\1)*(,|$)', '\1\3')
from demotable
group by group_id;  

This only works if you specify the delimiter to ',' not ', ' ie works only for no spaces after the comma. If you want spaces after the comma - here is a example how.

select 
replace(
    regexp_replace(
     regexp_replace('BBall, BBall, BBall, Football, Ice Hockey ',',\s*',',')            
    ,'([^,]+)(,\1)*(,|$)', '\1\3')
,',',', ') 
from dual

gives BBall, Football, Ice Hockey

To get your radio button to list horizontally , just add

RepeatDirection="Horizontal"

to your .aspx file where the asp:radiobuttonlist is being declared.

That's because abc is undefined at the moment of the template rendering. You can use safe navigation operator (?) to "protect" template until HTTP call is completed:

{{abc?.xyz?.name}}

You can read more about safe navigation operator here.

Update:

Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf directive to overcome this problem:

<div *ngIf="arr && arr.length > 0">
    {{arr[0].name}}
</div>

Read more about NgIf directive here.

Datetime formatting is performed by the org.joda.time.format.DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are ISODateTimeFormat and DateTimeFormatterBuilder.

DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd");
LocalDate lDate = new LocalDate().parse("2005-nov-12",format);

final org.joda.time.LocalDate class is an immutable datetime class representing a date without a time zone. LocalDate is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

I think you should try with :

While Semaphore initialization :

Semaphore semaphore = new Semaphore(1, true);

And in your Runnable Implementation

try 
{
   semaphore.acquire(1);
   // do stuff

}

Have you tried height: auto; on your .container div?

Here is a fiddle, if you change img height, container height will adjust to it.

EDIT

So if you "can't" change the inline min-height, you can overwrite the inline style with an !important parameter. It's not the cleanest way, but it solves your problem.

add to your .containerclass this line

min-height:0px !important;

I've updated my fiddle to give you an example.

You should try this:

df_total = data.frame()
for (i in 1:7){
    # vector output
    model <- #some processing

    # add vector to a dataframe
    df <- data.frame(model)
    df_total <- rbind(df_total,df)
}

    //Example to define how to do :

    DataTable dt = new DataTable();   

    dt.Columns.Add("ID");
    dt.Columns.Add("FirstName");
    dt.Columns.Add("LastName");
    dt.Columns.Add("Address");
    dt.Columns.Add("City");
           //  The table structure is:
            //ID    FirstName   LastName    Address     City

       //Now we want to add a PhoneNo column after the LastName column. For this we use the                               
             //SetOrdinal function, as iin:
        dt.Columns.Add("PhoneNo").SetOrdinal(3);

            //3 is the position number and positions start from 0.`enter code here`

               //Now the table structure will be:
              // ID      FirstName   LastName    PhoneNo    Address     City

Go to "Run" and execute this:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

NOTE: run as administrator.

Use docker ps to get the container id.

Then docker inspect -f '{{ .Mounts }}' containerid

Example:

terminal 1

$ docker run -it -v /tmp:/tmp ubuntu:14.04 /bin/bash

terminal 2

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
ddb7b55902cc        ubuntu:14.04        "/bin/bash"         About a minute ago   Up About a minute                       distracted_banach   

$ docker inspect -f "{{ .Mounts }}" ddb7
map[/tmp:/tmp]

The output

map[/tmp:/tmp] 

is, apparently, due to the use of the Go language to implement the docker command tools.

The docker inspect command without the -f format is quite verbose. Since it is JSON you could pipe it to python or nodejs and extract whatever you needed.

docker history <image name> will show the layers baked into an image. Unfortunately, docker history seems hobbled by its formatting and lack of options to choose what is displayed.

You can choose terse and verbose formats, via the --no-trunc flag.

The else clause is only executed when your while condition becomes false. If you break out of the loop, or if an exception is raised, it won't be executed.

One way to think about it is as an if/else construct with respect to the condition:

if condition:
    handle_true()
else:
    handle_false()

is analogous to the looping construct:

while condition:
    handle_true()
else:
    # condition is false now, handle and go on with the rest of the program
    handle_false()

An example might be along the lines of:

while value < threshold:
    if not process_acceptable_value(value):
        # something went wrong, exit the loop; don't pass go, don't collect 200
        break
    value = update(value)
else:
    # value >= threshold; pass go, collect 200
    handle_threshold_reached()

This will print the name and contents of files-only recursively..

find . -type f -printf '\n\n%p:\n' -exec cat {} \;

Edit (Improved version): This will print the name and contents of text (ascii) files-only recursively..

find . -type f -exec grep -Iq . {} \; -print | xargs awk 'FNR==1{print FILENAME ":" $0; }'

One more attempt

find . -type f -exec grep -Iq . {} \; -printf "\n%p:" -exec cat {} \;

To refresh the component at regular intervals I found this the best method. In the ngOnInit method setTimeOut function

ngOnInit(): void {
  setTimeout(() => { this.ngOnInit() }, 1000 * 10)
}
//10 is the number of seconds

This question doesn't really have anything to do with how require() works. Basically, whatever you set module.exports to in your module will be returned from the require() call for it.

This would be equivalent to:

var square = function(width) {
  return {
    area: function() {
      return width * width;
    }
  };
}

There is no need for the new keyword when calling square. You aren't returning the function instance itself from square, you are returning a new object at the end. Therefore, you can simply call this function directly.

For more intricate arguments around new, check this out: Is JavaScript's "new" keyword considered harmful?

It's not broken. It's doing exactly what you told it to; those pixels are black with full transparency. You will need to iterate across all pixels and convert ones with full transparency to white.

Swift 3.0

i had the same problem, i found on the documentation Apple this solution.

let numbers = [1, 2, 3, 4]
let addTwo: (Int, Int) -> Int = { x, y in x + y }
let numberSum = numbers.reduce(0, addTwo)
// 'numberSum' == 10

But, in my case i had a list of object, then i needed transform my value of my list:

let numberSum = self.list.map({$0.number_here}).reduce(0, { x, y in x + y })

this work for me.
