Try with this

public class ConnectionBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {


    if (<Check internet connection available >) { 
        Toast.makeText(context, "connect to the internet", Toast.LENGTH_LONG).show();

        /*upload background upload service*/
        Intent serviceIntent = new Intent(context,<your service class>);
        context.startService(serviceIntent);


    }else{
        Toast.makeText(context, "Connection failed", Toast.LENGTH_LONG).show();

    }
    }
}

As soon as internet connection trigger, this (BroadcastReciever) will be loaded

Use this code to check the internet connection

ConnectivityManager connectivityManager = (ConnectivityManager) ctx
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        if ((connectivityManager
                .getNetworkInfo(ConnectivityManager.TYPE_MOBILE) != null && connectivityManager
                .getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED)
                || (connectivityManager
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI) != null && connectivityManager
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI)
                        .getState() == NetworkInfo.State.CONNECTED)) {
            return true;
        } else {
            return false;
        }

try using ConnectivityManager

ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivity != null) {
        NetworkInfo[] info = connectivity.getAllNetworkInfo();
        if (info != null) {
            for (int i = 0; i < info.length; i++) {
                if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                    return true;
                }
            }
        }
    }
 return false

Also Add permission to AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

This is probably not always faster but more optimistic about that you find a big prime divisor:

1. N is your number
2. If it is prime then return(N)
3. Calculate primes up until Sqrt(N)
4. Go through the primes in descending order (largest first)
   • If N is divisible by Prime then Return(Prime)

Edit: In step 3 you can use the Sieve of Eratosthenes or Sieve of Atkins or whatever you like, but by itself the sieve won't find you the biggest prime factor. (Thats why I wouldn't choose SQLMenace's post as an official answer...)

To summarize, this points to current object and the method invocation in java is polymorphic by nature. So, method selection for execution, totally depends upon object pointed by this. Therefore, invoking method method2() from parent class invokes method2() of child class, as the this points to object of child class. The definition of this doesn't changes, irrespective of whichever class it's used.

PS. unlike methods, member variables of class are not polymorphic.

So many wrong answers!

To specify the value that a form field should revert to upon resetting the form, use the following properties:

• Checkbox or radio button: defaultChecked
• Any other <input> control: defaultValue
• Option in a drop down list: defaultSelected

So, to specify the currently selected option as the default:

var country = document.getElementById("country");
country.options[country.selectedIndex].defaultSelected = true;

It may be a good idea to set the defaultSelected value for every option, in case one had previously been set:

var country = document.getElementById("country");
for (var i = 0; i < country.options.length; i++) {
    country.options[i].defaultSelected = i == country.selectedIndex;
}

Now, when the form is reset, the selected option will be the one you specified.

I know that this question is old but i would like to contribute too:

The main difference between others responses is the hashmap return.

@GetMapping("...")
@ResponseBody
public Map<String, Object> endPointExample(...) {

    Map<String, Object> rtn = new LinkedHashMap<>();

    rtn.put("pic", image);
    rtn.put("potato", "King Potato");

    return rtn;

}

This will return:

{"pic":"a17fefab83517fb...beb8ac5a2ae8f0449","potato":"King Potato"}

My suggestion:

using System.Linq;

string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

reference: https://coderwall.com/p/oea7uq/convert-simple-int-array-to-string-c

Well if you want fully transparent than you can use

border: 5px solid transparent;

If you mean opaque/transparent, than you can use

border: 5px solid rgba(255, 255, 255, .5);

Here, a means alpha, which you can scale, 0-1.

Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.

For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.

Demo

Demo 2 (With a background image for nested div)

Demo 3 (With an img tag instead of a background-image)

body {
    background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);   
}

div.wrap {
    border: 5px solid #fff; /* Fall back, not used in fiddle */
    border: 5px solid rgba(255, 255, 255, .5);
    height: 400px;
    width: 400px;
    margin: 50px;
    border-radius: 50%;
}

div.inner {
    background: #fff; /* Fall back, not used in fiddle */
    background: rgba(255, 255, 255, .5);
    height: 380px;
    width: 380px;
    border-radius: 50%; 
    margin: auto; /* Horizontal Center */
    margin-top: 10px; /* Vertical Center ... Yea I know, that's 
                         manually calculated*/
}

Note (For Demo 3): Image will be scaled according to the height and width provided so make sure it doesn't break the scaling ratio.

All of the answers here work great if your divisor is positive, but it's not quite complete. Here is my implementation which always returns on a range of [0, b), such that the sign of the output is the same as the sign of the divisor, allowing for negative divisors as the endpoint for the output range.

PosMod(5, 3) returns 2
PosMod(-5, 3) returns 1
PosMod(5, -3) returns -1
PosMod(-5, -3) returns -2

    /// <summary>
    /// Performs a canonical Modulus operation, where the output is on the range [0, b).
    /// </summary>
    public static real_t PosMod(real_t a, real_t b)
    {
        real_t c = a % b;
        if ((c < 0 && b > 0) || (c > 0 && b < 0)) 
        {
            c += b;
        }
        return c;
    }

(where real_t can be any number type)

The following will print the line matching TERMINATE till the end of the file:

sed -n -e '/TERMINATE/,$p'

Explained: -n disables default behavior of sed of printing each line after executing its script on it, -e indicated a script to sed, /TERMINATE/,$ is an address (line) range selection meaning the first line matching the TERMINATE regular expression (like grep) to the end of the file ($), and p is the print command which prints the current line.

This will print from the line that follows the line matching TERMINATE till the end of the file:
(from AFTER the matching line to EOF, NOT including the matching line)

sed -e '1,/TERMINATE/d'

Explained: 1,/TERMINATE/ is an address (line) range selection meaning the first line for the input to the 1st line matching the TERMINATE regular expression, and d is the delete command which delete the current line and skip to the next line. As sed default behavior is to print the lines, it will print the lines after TERMINATE to the end of input.

Edit:

If you want the lines before TERMINATE:

sed -e '/TERMINATE/,$d'

And if you want both lines before and after TERMINATE in 2 different files in a single pass:

sed -e '1,/TERMINATE/w before
/TERMINATE/,$w after' file

The before and after files will contain the line with terminate, so to process each you need to use:

head -n -1 before
tail -n +2 after

Edit2:

IF you do not want to hard-code the filenames in the sed script, you can:

before=before.txt
after=after.txt
sed -e "1,/TERMINATE/w $before
/TERMINATE/,\$w $after" file

But then you have to escape the $ meaning the last line so the shell will not try to expand the $w variable (note that we now use double quotes around the script instead of single quotes).

I forgot to tell that the new line is important after the filenames in the script so that sed knows that the filenames end.

Edit: 2016-0530

Sébastien Clément asked: "How would you replace the hardcoded TERMINATE by a variable?"

You would make a variable for the matching text and then do it the same way as the previous example:

matchtext=TERMINATE
before=before.txt
after=after.txt
sed -e "1,/$matchtext/w $before
/$matchtext/,\$w $after" file

to use a variable for the matching text with the previous examples:

## Print the line containing the matching text, till the end of the file:
## (from the matching line to EOF, including the matching line)
matchtext=TERMINATE
sed -n -e "/$matchtext/,\$p"

## Print from the line that follows the line containing the 
## matching text, till the end of the file:
## (from AFTER the matching line to EOF, NOT including the matching line)
matchtext=TERMINATE
sed -e "1,/$matchtext/d"

## Print all the lines before the line containing the matching text:
## (from line-1 to BEFORE the matching line, NOT including the matching line)
matchtext=TERMINATE
sed -e "/$matchtext/,\$d"

The important points about replacing text with variables in these cases are:

1. Variables ($variablename) enclosed in single quotes ['] won't "expand" but variables inside double quotes ["] will. So, you have to change all the single quotes to double quotes if they contain text you want to replace with a variable.
2. The sed ranges also contain a $ and are immediately followed by a letter like: $p, $d, $w. They will also look like variables to be expanded, so you have to escape those $ characters with a backslash [\] like: \$p, \$d, \$w.

Let's give an example for int(10) one with zerofill keyword, one not, the table likes that:

create table tb_test_int_type(
    int_10 int(10),
    int_10_with_zf int(10) zerofill,
    unit int unsigned
);

Let's insert some data:

insert into tb_test_int_type(int_10, int_10_with_zf, unit)
values (123456, 123456,3147483647), (123456, 4294967291,3147483647) 
;

Then

select * from tb_test_int_type; 

# int_10, int_10_with_zf, unit
'123456', '0000123456', '3147483647'
'123456', '4294967291', '3147483647'

We can see that

• with keyword zerofill, num less than 10 will fill 0, but without zerofill it won't

• Secondly with keyword zerofill, int_10_with_zf becomes unsigned int type, if you insert a minus you will get error Out of range value for column...... But you can insert minus to int_10. Also if you insert 4294967291 to int_10 you will get error Out of range value for column.....

Conclusion:

1. int(X) without keyword zerofill, is equal to int range -2147483648~2147483647

2. int(X) with keyword zerofill, the field is equal to unsigned int range 0~4294967295, if num's length is less than X it will fill 0 to the left

I had to uninstall some external components like Postsharp and Apex and then it worked. I also tried the chosen solution but it gave me more errors.

Please refer to the official documentation:

https://www.chartjs.org/docs/latest/axes/styling.html#grid-line-configuration

Below code changes would hide the gridLines:

        gridLines: {
            display:false
        }

In C and languages based on the C syntax, the prefix 0x means hexadecimal (base 16).

Thus, 0x400 = 4×(16²) + 0×(16¹) + 0×(16⁰) = 4×((2⁴)²) = 2² × 2⁸ = 2¹⁰ = 1024, or one binary K.

And so 0x6400 = 0x4000 + 0x2400 = 0x19×0x400 = 25K

This will allow you to clear all the rows and maintain the format of the DataTable.

dt.Rows.Clear();

There is also

dt.Clear();

However, calling Clear() on the DataTable (dt) will remove the Columns and formatting from the DataTable.

Per code found in an MSDN question, an internal method is called by both the DataRowsCollection, and DataTable with a different boolean parameter:

internal void Clear(bool clearAll)
{
    if (clearAll) // true is sent from the Data Table call
    {
        for (int i = 0; i < this.recordCapacity; i++)
        {
            this.rows[i] = null;
        }
        int count = this.table.columnCollection.Count;
        for (int j = 0; j < count; j++)
        {
            DataColumn column = this.table.columnCollection[j];
            for (int k = 0; k < this.recordCapacity; k++)
            {
                column.FreeRecord(k);
            }
        }
        this.lastFreeRecord = 0;
        this.freeRecordList.Clear();
    }
    else // False is sent from the DataRow Collection
    {
        this.freeRecordList.Capacity = this.freeRecordList.Count + this.table.Rows.Count;
        for (int m = 0; m < this.recordCapacity; m++)
        {
            if ((this.rows[m] != null) && (this.rows[m].rowID != -1))
            {
                int record = m;
                this.FreeRecord(ref record);
            }
        }
    }
}

For simply checking against Object or Array without additional function call (speed).

isArray()

isArray = function(a) {
    return (!!a) && (a.constructor === Array);
};
console.log(isArray(        )); // false
console.log(isArray(    null)); // false
console.log(isArray(    true)); // false
console.log(isArray(       1)); // false
console.log(isArray(   'str')); // false
console.log(isArray(      {})); // false
console.log(isArray(new Date)); // false
console.log(isArray(      [])); // true

isObject()

isObject = function(a) {
    return (!!a) && (a.constructor === Object);
};
console.log(isObject(        )); // false
console.log(isObject(    null)); // false
console.log(isObject(    true)); // false

Take IISReset as a suite of commands that helps you manage IIS start / stop etc.

Which means you need to specify option (/switch) what you want to do to carry any operation.

Default behavior OR default switch is /restart with iisreset so you do not need to run command twice with /start and /stop.

Hope this clarifies your question. For reference the output of iisreset /? is:

IISRESET.EXE (c) Microsoft Corp. 1998-2005

Usage:
iisreset [computername]

    /RESTART            Stop and then restart all Internet services.
    /START              Start all Internet services.
    /STOP               Stop all Internet services.
    /REBOOT             Reboot the computer.
    /REBOOTONERROR      Reboot the computer if an error occurs when starting,
                        stopping, or restarting Internet services.
    /NOFORCE            Do not forcefully terminate Internet services if
                        attempting to stop them gracefully fails.
    /TIMEOUT:val        Specify the timeout value ( in seconds ) to wait for
                        a successful stop of Internet services. On expiration
                        of this timeout the computer can be rebooted if
                        the /REBOOTONERROR parameter is specified.
                        The default value is 20s for restart, 60s for stop,
                        and 0s for reboot.
    /STATUS             Display the status of all Internet services.
    /ENABLE             Enable restarting of Internet Services
                        on the local system.
    /DISABLE            Disable restarting of Internet Services
                        on the local system.

For Laravel 5.4+

'mobile_number_1' => 'required|numeric|min:0|regex:/^[789]\d{9}$/' should do the trick

i coped with same error and my suggestion are:

1. Start with try build another user in git lab
2. Recheck username & password (although it sounds obvious)
3. Validate the windows cerdential (start -> "cred")
4. Copy & paste same URL like you get from git lab, the struct should be:

http://{srvName}/{userInGitLab}/{Repository.git} no '/' at the end

5. Recheck the authorization in GitLab
6. Give an attention to case sensitive

Hope one of the above will solve it.

I think the most efficient way is to wrap the touchableOpacity with a view and add the prop pointerEvents with a style condition.

<View style={this.state.disabled && commonStyles.buttonDisabled}        
      pointerEvents={this.state.disabled ? "none" : "auto"}>
  <TouchableOpacity
    style={styles.connectButton}>
  <Text style={styles.connectButtonText}">CONNECT </Text>
  </TouchableOpacity>
</View>

CSS:

buttonDisabled: {
    opacity: 0.7
  }

Reason for the error:

Column expands to the maximum size in main axis direction (vertical axis), and so does the ListView.

Solutions

So, you need to constrain the height of the ListView. There are many ways of doing it, you can choose that best suits your need.

1. If you want to allow ListView to take up all remaining space inside Column use Expanded.

   Column(
     children: <Widget>[
       Expanded(
         child: ListView(...),
       )
     ],
   )
   

2. If you want to limit your ListView to certain height, you can use SizedBox.

   Column(
     children: <Widget>[
       SizedBox(
         height: 200, // constrain height
         child: ListView(),
       )
     ],
   )
   

3. If your ListView is small, you may try shrinkWrap property on it.

   Column(
     children: <Widget>[
       ListView(
         shrinkWrap: true, // use it
       )
     ],
   )
   

You can put title attribute to tag.I hope it will work.

<img src="smiley.gif" title="Smiley face" width="42" height="42">

Use ON DUPLICATE KEY UPDATE ...,
Negative : because the UPDATE uses resources for the second action.

Use INSERT IGNORE ...,
Negative : MySQL will not show any errors if something goes wrong, so you cannot handle the errors. Use it only if you don’t care about the query.

While, this is not technically what you want, if you know before hand the type of object you want to handle you can use the call/apply methods of the prototype of your known object.

you can change this

alert(fooJSON.test() ); //Prints 12

to this

alert(Foo.prototype.test.call(fooJSON); //Prints 12

Replacing :

SparkConf sparkConf = new SparkConf().setAppName("SOME APP NAME");
WITH
SparkConf sparkConf = new SparkConf().setAppName("SOME APP NAME").setMaster("local[2]").set("spark.executor.memory","1g");

Did the magic.

You could use HttpWebRequest to get the file and stream it back to the client. This allows you to get the file with a url. An example of this that I found ( but can't remember where to give credit ) is

    //Create a stream for the file
    Stream stream = null;

    //This controls how many bytes to read at a time and send to the client
    int bytesToRead = 10000;

    // Buffer to read bytes in chunk size specified above
    byte[] buffer = new Byte[bytesToRead];

    // The number of bytes read
    try
    {
      //Create a WebRequest to get the file
      HttpWebRequest fileReq = (HttpWebRequest) HttpWebRequest.Create(url);

      //Create a response for this request
      HttpWebResponse fileResp = (HttpWebResponse) fileReq.GetResponse();

      if (fileReq.ContentLength > 0)
        fileResp.ContentLength = fileReq.ContentLength;

        //Get the Stream returned from the response
        stream = fileResp.GetResponseStream();

        // prepare the response to the client. resp is the client Response
        var resp = HttpContext.Current.Response;

        //Indicate the type of data being sent
        resp.ContentType = "application/octet-stream";

        //Name the file 
        resp.AddHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
        resp.AddHeader("Content-Length", fileResp.ContentLength.ToString());

        int length;
        do
        {
            // Verify that the client is connected.
            if (resp.IsClientConnected)
            {
                // Read data into the buffer.
                length = stream.Read(buffer, 0, bytesToRead);

                // and write it out to the response's output stream
                resp.OutputStream.Write(buffer, 0, length);

                // Flush the data
                resp.Flush();

                //Clear the buffer
                buffer = new Byte[bytesToRead];
            }
            else
            {
                // cancel the download if client has disconnected
                length = -1;
            }
        } while (length > 0); //Repeat until no data is read
    }
    finally
    {
        if (stream != null)
        {
            //Close the input stream
            stream.Close();
        }
    }

Following chrome options worked for me for headless chrome:

IN JAVA:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--window-size=1920,1080");
chromeOptions.setHeadless(true);
driver = new ChromeDriver(chromeOptions);
driver.get("your-site");
driver.manage().window().maximize();

    margin-right: 2px;
    position: absolute;

}

In my case, using Mockito 2.0, I had to change all the any() parameters to nullable() in order to stub the real call.

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

Although it is much easier to restore database using SSMS as stated in many answers. You can also restore Database using .bak with SQL server query, for example

RESTORE DATABASE AdventureWorks2012 FROM DISK = 'D:\AdventureWorks2012.BAK'
GO

In above Query you need to keep in mind about .mdf/.ldf file location. You might get error

System.Data.SqlClient.SqlError: Directory lookup for the file "C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\AdventureWorks.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.SmoExtended)

So you need to run Query as below

RESTORE FILELISTONLY 
FROM DISK = 'D:\AdventureWorks2012.BAK'

Once you will run above Query you will get location of mdf/ldf use it Restore database using query

USE MASTER
GO
RESTORE DATABASE DBASE 
FROM DISK = 'D:\AdventureWorks2012.BAK'
WITH 
MOVE 'DBASE' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE.MDF',
MOVE 'DBASE_LOG' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE_1.LDF', 
NOUNLOAD,  REPLACE,  NOUNLOAD,  STATS = 5
GO

Well, after long research, i found a workaround that does what i need: http://jsfiddle.net/CqB3d/25/

CSS:

body{
    margin: 0;
    padding: 0;
    border: 0;
    overflow: hidden;
    height: 100%; 
    max-height: 100%; 
}

#caixa{
    width: 800px;
    margin-left: auto;
    margin-right: auto;
}
#framecontentTop, #framecontentBottom{
    position: absolute; 
    top: 0;   
    width: 800px; 
    height: 100px; /*Height of top frame div*/
    overflow: hidden; /*Disable scrollbars. Set to "scroll" to enable*/
    background-color: navy;
    color: white; 
}

#framecontentBottom{

    overflow: auto; 
    background: #fff;
    width: 800px;
}

.innertube{
    margin: 15px; /*Margins for inner DIV inside each DIV (to provide padding)*/
}

* html body{ /*IE6 hack*/
    padding: 130px 0 110px 0; /*Set value to (HeightOfTopFrameDiv 0 HeightOfBottomFrameDiv 0)*/
}

* html #maincontent{ /*IE6 hack*/
    height: 100%; 
    width: 800px; 
}

HTML:

<div id="framecontentBottom">
    <div class="innertube">
        <h3>Sample text here</h3>
    </div>
</div>
<div id="maincontent">
    <div class="innertube">

Phasellus sed suscipit dolor. Quisque at mi dolor, eu fermentum turpis. Nunc posuere venenatis est, in sagittis nulla consectetur eget... //much longer text...
    </div>
</div>

might not work with the horizontal thingy yet, but, it's a work in progress!

I basically dropped the "inception" boxes-inside-boxes-inside-boxes model and used fixed positioning with dynamic height and overflow properties.

Hope this might help whoever finds the question later!

EDIT: This is the final answer.

LINQ to XML Example:

// Loading from a file, you can also load from a stream
var xml = XDocument.Load(@"C:\contacts.xml");


// Query the data and write out a subset of contacts
var query = from c in xml.Root.Descendants("contact")
            where (int)c.Attribute("id") < 4
            select c.Element("firstName").Value + " " +
                   c.Element("lastName").Value;


foreach (string name in query)
{
    Console.WriteLine("Contact's Full Name: {0}", name);
}

Reference: LINQ to XML at MSDN

cursor.fetchall() and list(cursor) are essentially the same. The different option is to not retrieve a list, and instead just loop over the bare cursor object:

for result in cursor:

This can be more efficient if the result set is large, as it doesn't have to fetch the entire result set and keep it all in memory; it can just incrementally get each item (or batch them in smaller batches).

Also think about using

$(document).ready(function() {});

Don't know why no one here came up with this yet (kinda sad). When do you execute your code??? Right at the start? Then you might want to use upper mentioned ready() function so your code is being executed after the whole page (with all it's dom elements) has been loaded and not before! Of course this is useless if you run some code that adds dom elements after page load! Then you simply want to wait for those functions and execute your code afterwards...

Use the replace() method on string:

>>> stuff = "Big and small"
>>> stuff.replace( " and ", "/" )
'Big/small'

I have faced the same issue when I tried to install xampp on windows 8.1. The problem in my system was there was no password for the current logged in user account. After creating the password then I tried to install xampp. It installed without any issue. Hope it helps someone in the feature.

You can open multiple browser or a window by using below code:

WebDriver driver = new ChromeDriver();
driver.get("http://yahoo.com");  

WebDriver driver1 = new ChromeDriver();
driver1.get("google.com");

WebDriver driver2 = new InternetExplorerDriver();
driver2.get("google.com/gmap");

If you miss, Microsoft.CSharp.dll this error can occur. Check you project references.

Run SDK Manager as Admin will solve your problem

I was looking for a similar solution and this is what I would suggest. In the OnTouch method, record the time for MotionEvent.ACTION_DOWN event and then for MotionEvent.ACTION_UP, record the time again. This way you can set your own threshold also. After experimenting few times you will know the max time in millis it would need to record a simple touch and you can use this in move or other method as you like.

Hope this helped. Please comment if you used a different method and solved your problem.

Not sure if my data matched exactly but I had an array of arrays of JSON objects, that got exported from jQuery FormBuilder when using pages.

Hopefully my answer can help anyone who stumbles onto this question looking for an answer to a problem similar to what I had.

The data looked somewhat like this:

var allData = 
[
    [
        {
            "type":"text",
            "label":"Text Field"
        }, 
        {
            "type":"text",
            "label":"Text Field"
        }
    ],
    [
        {
            "type":"text",
            "label":"Text Field"
        }, 
        {
            "type":"text",
            "label":"Text Field"
        }
    ]
]

What I did to parse this was to simply do the following:

JSON.parse("["+allData.toString()+"]")

Try this,this is working for me in angular JS

    let fileToUpload = `${documentLocation}/${documentType}.pdf`;
    let absoluteFilePath = path.resolve(__dirname, fileToUpload);
    console.log(`Uploading document ${absoluteFilePath}`);
    element.all(by.css("input[type='file']")).sendKeys(absoluteFilePath);

import re

url = '<p>Hello World</p><a href="http://example.com">More Examples</a><a href="http://example2.com">Even More Examples</a>'

urls = re.findall('https?://(?:[-\w.]|(?:%[\da-fA-F]{2}))+', url)

>>> print urls
['http://example.com', 'http://example2.com']

i uses Js function replace simply.

<Text>{item.excerpt.rendered.replace(/<\/?[^>]+(>|$)/g, "")}</Text>

I lack the reputation to comment but ctime from Marlon Abeykoons response did not give the correct result for me. Using mtime does the trick though. (key=os.path.getmtime))

import glob
import os

list_of_files = glob.glob('/path/to/folder/*') # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getmtime)
print latest_file

I found two answers for that problem:

python os.path.getctime max does not return latest Difference between python - getmtime() and getctime() in unix system

I am using React Bootstrap, which is based on Bootstrap 4. The approach is to use Sass, simliar to Nelson Rothermel's answer above.

The idea is to override Bootstraps Sass variable for font family in your custom Sass file. If you are using Google Fonts, then make sure you import it at the top of your custom Sass file.

For example, my custom Sass file is called custom.sass with the following content:

@import url('https://fonts.googleapis.com/css2?family=Dancing+Script&display=swap');
   
$font-family-sans-serif: "Dancing Script", -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, "Noto Sans", sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji" !default;

I simply added the font I want to the front of the default values, which can be found in ..\node_modules\boostrap\dist\scss\_variables.scss.

How the custom.scss file is used is shown here, which is obtained from here, which is obtained from here...

Because the React app is created by the Create-React-App utility, there's no need to go through all the crufts like Gulp; I just saved the files and React will compile the Sass for me automagically behind the scene.

Everybody has the right idea, but I like to be a little more explicit and trim the values.

$('#apply-form input').blur(function() {
     if(!$.trim(this.value).length) { // zero-length string AFTER a trim
            $(this).parents('p').addClass('warning');
     }
});

if you dont use .length , then an entry of '0' can get flagged as bad, and an entry of 5 spaces could get marked as ok without the $.trim . Best of Luck.

For me the problem was an error that didn't come up in the build output, namely I had two utility classes that were in different namespaces initially. I changed the namespace of the second one to match the first one's (without knowing there was another one utility class in the first one), and that's when this error started to come up.

I imagine the build output error surfaced, because the Logic Layer library DLL file could not be built, and the main application couldn't find it.

The solution was to change back the second utility class to a different namespace and that's when the real build errors started to pour in. After sorting them out the build went through just fine.

As an overview, if any of the previous solutions doesn't work for you, you might have suppressed errors in the code that Visual Studio is not showing, so try to retrack your coding steps and check for any irregularities.

PS: This was in Visual Studio 2015 Community Edition

Ken had it right as well.

a css tag:

audio {

}

will get you some results. seems it doesnt want the player any height above or below 25px but the width can be shortened or lengthened to an extent.

this was good enough for me; see this example (warning, audio plays automatically): www.thenewyorkerdeliinc.com

You can get desired behavior by listening when user hit "Done" button on keyboard, also checkout other tips about working with EditText in my post "Android form validation - the right way"

Sample code:

mTextView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_DONE) {                    
            validateAndSubmit();
            return true;
        }
        return false;
    }});  

When you make a call to using namespace <some_namespace>; all symbols in that namespace will become visible without adding the namespace prefix. A symbol may be for instance a function, class or a variable.

E.g. if you add using namespace std; you can write just cout instead of std::cout when calling the operator cout defined in the namespace std.

This is somewhat dangerous because namespaces are meant to be used to avoid name collisions and by writing using namespace you spare some code, but loose this advantage. A better alternative is to use just specific symbols thus making them visible without the namespace prefix. Eg:

#include <iostream>
using std::cout;

int main() {
  cout << "Hello world!";
  return 0;
}

JButton close = new JButton("Close");
close.addActionListener(this);
public void actionPerformed(ActionEvent closing) { 
// getSource() checks for the source of clicked Button , compares with the name of button in which here is close .     
if(closing.getSource()==close)
   System.exit(0);
   // This exit Your GUI 
}
/*Some Answers were asking for @override which is overriding the method the super class or the parent class and creating different objects and etc which makes the answer too long . Note : we just need to import java.awt.*; and java.swing.*; and Adding this command : class className implements actionListener{} */

ID is an attribute, you can set it with the attr function:

$(element).attr('id', 'newID');

I'm not sure what you mean about adding IDs since an element can only have one identifier and this identifier must be unique.

Html code:

Change Title:
<input type="text" id="changeTitle" placeholder="Enter title tag">
<button id="changeTitle1">Click!</button>

Jquery code:

$(document).ready(function(){   
    $("#changeTitle1").click(function() {
        $(document).prop('title',$("#changeTitle").val()); 
    });
});

Label1.Text = dt.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");

will output:

07 Mai 2009 | 08:16 | 13 | +02:00 | +02 | +2

I'm in Denmark, my Offset from GMT is +2 hours, witch is correct.

if you need to get the CLIENT Offset, I recommend that you check a little trick that I did. The Page is in a Server in UK where GMT is +00:00 and, as you can see you will get your local GMT Offset.

Regarding you comment, I did:

DateTime dt1 = DateTime.Now;
DateTime dt2 = dt1.ToUniversalTime();

Label1.Text = dt1.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");
Label2.Text = dt2.ToString("dd MMM yyyy | hh:mm | FF | ZZZ | ZZ | Z");

and I get this:

07 Mai 2009 | 08:24 | 14 | +02:00 | +02 | +2
07 Mai 2009 | 06:24 | 14 | ZZZ | ZZ | Z 

I get no Exception, just ... it does nothing with capital Z :(

I'm sorry, but am I missing something?

Reading carefully the MSDN on Custom Date and Time Format Strings

there is no support for uppercase 'Z'.

They must have included this as a feature, because now setting a different @JsonProperty for a getter and setter results in exactly what you would expect (different property name during serialization and deserialization for the same field). Jackson version 2.6.7

The easyest way is to change .attr() function to a javascript function .setAttribute()

$('#stop').click(function() {
    $('next')[0].setAttribute('onclick','stopMoving()');
}

Use the response.info() method to get the headers.

From the urllib2 docs:

urllib2.urlopen(url[, data][, timeout])

...

This function returns a file-like object with two additional methods:

• geturl() — return the URL of the resource retrieved, commonly used to determine if a redirect was followed
• info() — return the meta-information of the page, such as headers, in the form of an httplib.HTTPMessage instance (see Quick Reference to HTTP Headers)

So, for your example, try stepping through the result of response.info().headers for what you're looking for.

Note the major caveat to using httplib.HTTPMessage is documented in python issue 4773.

what about Result_* there also are generated in the loop (because i don't think it's possible to add to the csv file)

i will go like this ; generate all the data at one rotate the matrix write in the file:

A = []

A.append(range(1, 5))  # an Example of you first loop

A.append(range(5, 9))  # an Example of you second loop

data_to_write = zip(*A)

# then you can write now row by row

kubeadm reset 
/*On Debian base Operating systems you can use the following command.*/
# on debian base 
sudo apt-get purge kubeadm kubectl kubelet kubernetes-cni kube* 


/*On CentOs distribution systems you can use the following command.*/
#on centos base
sudo yum remove kubeadm kubectl kubelet kubernetes-cni kube*


# on debian base
sudo apt-get autoremove

#on centos base
sudo yum autoremove

/For all/
sudo rm -rf ~/.kube

Always try to do an associative fetch, that way you can easy get what you want in multiple case result

Here's an example

$result = $mysqli->query("SELECT COUNT(*) AS cityCount FROM myCity")
$row = $result->fetch_assoc();
echo $row['cityCount']." rows in table myCity.";

You could do:

Color c = Color.FromArgb(red, green, blue); //red, green and blue are integer variables containing red, green and blue components

FYI - getDay() will give you the day of the week... ie: if today is Thursday, it will return the number 4 (being the 4th day of the week).

To get a proper day of the month, use getDate().

My example below... (also a string padding function to give a leading 0 on single time elements. (eg: 10:4:34 => 10:04:35)

function strpad00(s)
{
    s = s + '';
    if (s.length === 1) s = '0'+s;
    return s;
}

var currentdate = new Date();
var datetime = currentdate.getDate() 
    + "/" + strpad00((currentdate.getMonth()+1)) 
    + "/" + currentdate.getFullYear() 
    + " @ " 
    + currentdate.getHours() + ":" 
    + strpad00(currentdate.getMinutes()) + ":" 
    + strpad00(currentdate.getSeconds());

Example output: 31/12/2013 @ 10:07:49
If using getDay(), the output would be 4/12/2013 @ 10:07:49

On Linux/Unix (note: Mac OS is a Unix) use top and press M (Shift+M) to sort processes by memory usage.

On Windows use the Task Manager.

In my case the solution was quite simple. I added this header and the browsers opened the file in every test. header('Content-Disposition: attachment; filename="filename.pdf"');

Try using online generator css3.me Change the value and get the code, pretty simple.

You can use elementFromPoint:

document.elementFromPoint(x, y);

supported in all browsers: https://caniuse.com/#feat=element-from-point

import traceback
traceback.print_exc()

When doing this inside an except ...: block it will automatically use the current exception. See http://docs.python.org/library/traceback.html for more information.

Here is the solution I was looking for. If you would like to create List2 that contains the difference of the number elements in List1.

list1 = [12, 15, 22, 54, 21, 68, 9, 73, 81, 34, 45]
list2 = []
for i in range(1, len(list1)):
  change = list1[i] - list1[i-1]
  list2.append(change)

Note that while len(list1) is 11 (elements), len(list2) will only be 10 elements because we are starting our for loop from element with index 1 in list1 not from element with index 0 in list1

You can use Apache POI for creating native binary xls files.

Or you can use JExcelApi which is another, and somewhat light-weight as far as I can remember, Java library for Excel.

I could not access the context object directly.
My solution is as following:

Context appContext = Android.App.Application.Context;
var wifiManager = (WifiManager)appContext.GetSystemService(WifiService);
wifiManager.SetWifiEnabled(state);

Also I had to change some writings eg. WIFI_SERVICE vs. WifiService.

You should be using where, select is a projection that returns the output of the statement, thus why you get boolean values. where is a filter that keeps the structure of the dataframe, but only keeps data where the filter works.

Along the same line though, per the documentation, you can write this in 3 different ways

// The following are equivalent:
peopleDf.filter($"age" > 15)
peopleDf.where($"age" > 15)
peopleDf($"age" > 15)

public static String readClob(Clob clob) throws SQLException, IOException {
    StringBuilder sb = new StringBuilder((int) clob.length());
    Reader r = clob.getCharacterStream();
    char[] cbuf = new char[2048];
    int n;
    while ((n = r.read(cbuf, 0, cbuf.length)) != -1) {
        sb.append(cbuf, 0, n);
    }
    return sb.toString();
}

The above approach is also very efficient.

I think you might be looking for an "anchor" given the example you have.

<a href="#jump">This link will jump to the anchor named jump</a>
<a name="jump">This is where the link will jump to</a>

The focus jQuery method does something different from what you're trying to achieve.

Using this:

if (navigator.userAgent.match("MSIE")) {}

Replace the comma with a dot.

This will only return 554:

var value = parseFloat("554,20")

This will return 554.20:

var value = parseFloat("554.20")

So in the end, you can simply use:

var fValue = parseFloat(document.getElementById("textfield").value.replace(",","."))

Don't forget that parseInt() should only be used to parse integers (no floating points). In your case it will only return 554. Additionally, calling parseInt() on a float will not round the number: it will take its floor (closest lower integer).

Extended example to answer Pedro Ferreira's question from the comments:

If the textfield contains thousands separator dots like in 1.234.567,99 those could be eliminated beforehand with another replace:

var fValue = parseFloat(document.getElementById("textfield").value.replace(/\./g,"").replace(",","."))

A Simple Approach will be to use a normal link and add Bootstrap modal effect to it. Just make use of my Code, hopefully you will get it run.

 <div class="container">
        <div class="row">
            <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="addContact" aria-hidden="true">

I had similar issue with the index.html being cached by the browser or more tricky by middle cdn/proxies (F5 will not help you).

I looked for a solution which verifies 100% that the client has the latest index.html version, luckily I found this solution by Henrik Peinar:

https://blog.nodeswat.com/automagic-reload-for-clients-after-deploy-with-angular-4-8440c9fdd96c

The solution solve also the case where the client stays with the browser open for days, the client checks for updates on intervals and reload if newer version deployd.

The solution is a bit tricky but works like a charm:

• use the fact that ng cli -- prod produces hashed files with one of them called main.[hash].js
• create a version.json file that contains that hash
• create an angular service VersionCheckService that checks version.json and reload if needed.
• Note that a js script running after deployment creates for you both version.json and replace the hash in angular service, so no manual work needed, but running post-build.js

Since Henrik Peinar solution was for angular 4, there were minor changes, I place also the fixed scripts here:

VersionCheckService :

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class VersionCheckService {
    // this will be replaced by actual hash post-build.js
    private currentHash = '{{POST_BUILD_ENTERS_HASH_HERE}}';

    constructor(private http: HttpClient) {}

    /**
     * Checks in every set frequency the version of frontend application
     * @param url
     * @param {number} frequency - in milliseconds, defaults to 30 minutes
     */
    public initVersionCheck(url, frequency = 1000 * 60 * 30) {
        //check for first time
        this.checkVersion(url); 

        setInterval(() => {
            this.checkVersion(url);
        }, frequency);
    }

    /**
     * Will do the call and check if the hash has changed or not
     * @param url
     */
    private checkVersion(url) {
        // timestamp these requests to invalidate caches
        this.http.get(url + '?t=' + new Date().getTime())
            .subscribe(
                (response: any) => {
                    const hash = response.hash;
                    const hashChanged = this.hasHashChanged(this.currentHash, hash);

                    // If new version, do something
                    if (hashChanged) {
                        // ENTER YOUR CODE TO DO SOMETHING UPON VERSION CHANGE
                        // for an example: location.reload();
                        // or to ensure cdn miss: window.location.replace(window.location.href + '?rand=' + Math.random());
                    }
                    // store the new hash so we wouldn't trigger versionChange again
                    // only necessary in case you did not force refresh
                    this.currentHash = hash;
                },
                (err) => {
                    console.error(err, 'Could not get version');
                }
            );
    }

    /**
     * Checks if hash has changed.
     * This file has the JS hash, if it is a different one than in the version.json
     * we are dealing with version change
     * @param currentHash
     * @param newHash
     * @returns {boolean}
     */
    private hasHashChanged(currentHash, newHash) {
        if (!currentHash || currentHash === '{{POST_BUILD_ENTERS_HASH_HERE}}') {
            return false;
        }

        return currentHash !== newHash;
    }
}

change to main AppComponent:

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
    constructor(private versionCheckService: VersionCheckService) {

    }

    ngOnInit() {
        console.log('AppComponent.ngOnInit() environment.versionCheckUrl=' + environment.versionCheckUrl);
        if (environment.versionCheckUrl) {
            this.versionCheckService.initVersionCheck(environment.versionCheckUrl);
        }
    }

}

The post-build script that makes the magic, post-build.js:

const path = require('path');
const fs = require('fs');
const util = require('util');

// get application version from package.json
const appVersion = require('../package.json').version;

// promisify core API's
const readDir = util.promisify(fs.readdir);
const writeFile = util.promisify(fs.writeFile);
const readFile = util.promisify(fs.readFile);

console.log('\nRunning post-build tasks');

// our version.json will be in the dist folder
const versionFilePath = path.join(__dirname + '/../dist/version.json');

let mainHash = '';
let mainBundleFile = '';

// RegExp to find main.bundle.js, even if it doesn't include a hash in it's name (dev build)
let mainBundleRegexp = /^main.?([a-z0-9]*)?.js$/;

// read the dist folder files and find the one we're looking for
readDir(path.join(__dirname, '../dist/'))
  .then(files => {
    mainBundleFile = files.find(f => mainBundleRegexp.test(f));

    if (mainBundleFile) {
      let matchHash = mainBundleFile.match(mainBundleRegexp);

      // if it has a hash in it's name, mark it down
      if (matchHash.length > 1 && !!matchHash[1]) {
        mainHash = matchHash[1];
      }
    }

    console.log(`Writing version and hash to ${versionFilePath}`);

    // write current version and hash into the version.json file
    const src = `{"version": "${appVersion}", "hash": "${mainHash}"}`;
    return writeFile(versionFilePath, src);
  }).then(() => {
    // main bundle file not found, dev build?
    if (!mainBundleFile) {
      return;
    }

    console.log(`Replacing hash in the ${mainBundleFile}`);

    // replace hash placeholder in our main.js file so the code knows it's current hash
    const mainFilepath = path.join(__dirname, '../dist/', mainBundleFile);
    return readFile(mainFilepath, 'utf8')
      .then(mainFileData => {
        const replacedFile = mainFileData.replace('{{POST_BUILD_ENTERS_HASH_HERE}}', mainHash);
        return writeFile(mainFilepath, replacedFile);
      });
  }).catch(err => {
    console.log('Error with post build:', err);
  });

simply place the script in (new) build folder run the script using node ./build/post-build.js after building dist folder using ng build --prod

First off, let me express that this is generally not the way to go about things in React land. Usually what you want to do is pass down functionality to children in props, and pass up notifications from children in events (or better yet: dispatch).

But if you must expose an imperative method on a child component, you can use refs. Remember this is an escape hatch and usually indicates a better design is available.

Previously, refs were only supported for Class-based components. With the advent of React Hooks, that's no longer the case

Use SHOW VARIABLES:

show variables like 'version';

If your arrays are not string arrays, use: memcpy(array2, array1, sizeof(array2));

put this inside your Manifest like this in No fullscreen Mode

android:windowSoftInputMode="stateVisible|adjustPan" 

in your manifest

<activity
    android:windowSoftInputMode="stateVisible|adjustPan"

I ran into the same problem and stuck for a long. The following steps saved me. Go through the constraints and change the onDelete ReferentialAction to NoAction from Cascade

  constraints: table =>
  {
      table.PrimaryKey("PK_table1", x => x.Id);
      table.ForeignKey(
         name: "FK_table1_table2_table2Id",
         column: x => x.table2Id,
         principalTable: "table2",
         principalColumn: "Id",
         onDelete: ReferentialAction.NoAction);
  });

bool containsCharacter = test.IndexOf("s", StringComparison.OrdinalIgnoreCase) >= 0;

Understanding that you're probably talking about a local/desktop machine and would probably like to continue talking about a local/desktop machine, I'll throw an alternative out there for you just in case it might help you or someone else:

Set up multiple virtual server instances in the cloud, and share your code between them as a git repository (or mercurial, I suppose, though I have no personal experience all you really need is something decentralized). This has the benefit of giving you as close to a production experience as possible, and if you have experience setting up servers then it's not that complicated (or expensive, if you just want to spin a server up, do what you need to do, then spin it down again, then you're talking about a few cents up to say 50 cents, up to a few bucks if you just leave it running).

I do all of my project development in the cloud these days and I've found it much simpler to manage the infrastructure than I ever did when using local/non-virtualized installs, and it makes this sort of side-by-side scenario fairly straight forward. I just wanted to throw the idea out there if you hadn't considered it.

I do not pretend to show something new, just want to summarize solutions above for those who likes to use Promise functions in their code (like me).

const archiver = require('archiver');

/**
 * @param {String} source
 * @param {String} out
 * @returns {Promise}
 */
function zipDirectory(source, out) {
  const archive = archiver('zip', { zlib: { level: 9 }});
  const stream = fs.createWriteStream(out);

  return new Promise((resolve, reject) => {
    archive
      .directory(source, false)
      .on('error', err => reject(err))
      .pipe(stream)
    ;

    stream.on('close', () => resolve());
    archive.finalize();
  });
}

Hope it will help someone ;)

Your code is

urlpatterns = [
    url(r'^$', 'myapp.views.home'),
    url(r'^contact/$', 'myapp.views.contact'),
    url(r'^login/$', 'django.contrib.auth.views.login'),
]

change it to following as you're importing include() function :

urlpatterns = [
    url(r'^$', views.home),
    url(r'^contact/$', views.contact),
    url(r'^login/$', views.login),
]

You can get the current date in a locale-agnostic way using

for /f "skip=1" %%x in ('wmic os get localdatetime') do if not defined MyDate set MyDate=%%x

Then you can extract the individual parts using substrings:

set today=%MyDate:~0,4%-%MyDate:~4,2%-%MyDate:~6,2%

Another way, where you get variables that contain the individual parts, would be:

for /f %%x in ('wmic path win32_localtime get /format:list ^| findstr "="') do set %%x
set today=%Year%-%Month%-%Day%

Much nicer than fiddling with substrings, at the expense of polluting your variable namespace.

If you need UTC instead of local time, the command is more or less the same:

for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x
set today=%Year%-%Month%-%Day%

I think comboBox1.Items.Add("X"); will add string to ComboBox, instead of ComboBoxItem.

The right solution is

ComboBoxItem item = new ComboBoxItem();
item.Content = "A";
comboBox1.Items.Add(item);

I'm astonished by the second number you mention (and confirm by your requested rounding) -- at first I thought my instinct for mental arithmetic was starting to fail me (I am getting older, after all, so that might be going the same way as my once-sharp memory!-)... but then I confirmed it hasn't, yet, by using, as I imagine you are, Python 3.1, and copying and pasting..:

>>> def input_meal():  
...     mealPrice = input('Enter the meal subtotal: $')  
...     mealPrice = float (mealPrice)  
...     return mealPrice  
... 
>>> def calc_tax(mealPrice):  
...     tax = mealPrice*.06  
...     return tax
... 
>>> m = input_meal()
Enter the meal subtotal: $34.45
>>> print(calc_tax(m))
2.067
>>> 

...as expected -- yet, you say it instead "returns a display of $ 2.607"... which might be a typo, just swapping two digits, except that you then ask "How can I set that to $2.61 instead?" so it really seems you truly mean 2.607 (which might be rounded to 2.61 in various ways) and definitely not the arithmetically correct result, 2.067 (which at best might be rounded to 2.07... definitely not to 2.61 as you request).

I imagine you first had the typo occur in transcription, and then mentally computed the desired rounding from the falsified-by-typo 2.607 rather than the actual original result -- is that what happened? It sure managed to confuse me for a while!-)

Anyway, to round a float to two decimal digits, simplest approach is the built-in function round with a second argument of 2:

>>> round(2.067, 2)
2.07
>>> round(2.607, 2)
2.61

For numbers exactly equidistant between two possibilities, it rounds-to-even:

>>> round(2.605, 2)
2.6
>>> round(2.615, 2)
2.62

or, as the docs put it (exemplifying with the single-argument form of round, which rounds to the closest integer):

if two multiples are equally close, rounding is done toward the even choice (so, for example, both round(0.5) and round(-0.5) are 0, and round(1.5) is 2).

However, for computations on money, I second the recommendation, already given in other answers, to stick with what the decimal module offers, instead of float numbers.

If you're rolling your own I'd highly recommend looking at http://effbot.org/zone/element-soap.htm.

I think the problem you're running into is that, even though you can set your own umask values in the system, this does not allow you to explicitly control the default permissions set on a new file by gedit (or whatever editor you use).

I believe this detail is hard-coded into gedit and most other editors. Your options for changing it are (a) hacking up your own mod of gedit or (b) finding a text editor that allows you to set a preference for default permissions on new files. (Sorry, I know of none.)

In light of this, it's really not so bad to have to chmod your files, right?

How to reproduce the error, and how to fix it:

1. Put this code in a file called p.php:

   <?php
   class yoyo{
       function salt(){
       }
       function pepper(){
           salt();
       }
   }
   $y = new yoyo();
   $y->pepper();
   ?>
   

2. Run it like this:

   php p.php
   

3. We get error:

   PHP Fatal error:  Call to undefined function salt() in 
   /home/el/foo/p.php on line 6
   

4. Solution: use $this->salt(); instead of salt();

   So do it like this instead:

   <?php
   class yoyo{
       function salt(){
       }
       function pepper(){
           $this->salt();
       }
   }
   $y = new yoyo();
   $y->pepper();
   
   ?>
   

If someone could post a link to why $this has to be used before PHP functions within classes, yeah, that would be great.

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

Answer : wait for few seconds before element visibility using Selenium WebDriver go through below methods.

implicitlyWait() : WebDriver instance wait until full page load. You muse use 30 to 60 seconds to wait full page load.

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

ExplicitlyWait WebDriverWait() : WebDriver instance wait until full page load.

WebDriverWait wait = new WebDriverWait(driver, 60);

wait.until(ExpectedConditions.visibilityOf(textbox));

driver.findElement(By.id("Year")).sendKeys(allKeys);

Note : Please use ExplicitlyWait WebDriverWait() to handle any particular WebElement.

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

This is not a proper answer but a troubleshooter, hopefully helps other less seasoned networkers like me.

In my case (firefox+ubuntu16) the browser was connecting, but showing a blank page (with the tensorboard logo on the tab), and no log activity at all was shown. I still don't know what could be the reason for that (didn't look much into it but if anybody knows please let know!), but I solved it switching to ubuntu's default browser. Here the exact steps, pretty much the same as in @Olivier Moindrot's answer:

1. On the server, start tensorboard: tensorboard --logdir=. --host=localhost --port=6006
2. On the client, open the ssh tunnel ssh -p 23 <USER>@<SERVER> -N -f -L localhost:16006:localhost:6006
3. Open ubuntu's Browser and visit localhost:16006. The tensorboard page should load without much delay.

To check that the SSH tunnel is effectively working, a simple echo server like this python script can help:

1. Put the script into an <ECHO>.py file in the server and run it with python <ECHO>.py. Now the server will have the echo script listening on 0.0.0.0:5555.
2. On the client, open the ssh tunnel ssh -p <SSH_PORT> <USER>@<SERVER> -N -f -L localhost:12345:localhost:5555
3. On the client, in the same terminal used to open the tunnel (step 2.), issuing telnet localhost 12345 will connect to the echo script running in the server. Typing hello and pressing enter should print hello back. If that is the case, your SSH tunnel is working. This was my case, and lead me to the conclusion that the problem involved the browser. Trying to connect from a different terminal caused the terminal to freeze.

As I said, hope it helps!
Cheers,
Andres

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

It looks like Microsoft invaded brains of all other respondents and made them write as complicated solutions as possible. Here is the simplest way without any additional functions/declare statements:

SELECT geography::Point(LATITUDE_1, LONGITUDE_1, 4326).STDistance(geography::Point(LATITUDE_2, LONGITUDE_2, 4326))

Simply substitute your data instead of LATITUDE_1, LONGITUDE_1, LATITUDE_2, LONGITUDE_2 e.g.:

SELECT geography::Point(53.429108, -2.500953, 4326).STDistance(geography::Point(c.Latitude, c.Longitude, 4326))
from coordinates c

you can render in following way

{{ post.published_at|date("m/d/Y") }}

For more details can visit http://twig.sensiolabs.org/doc/filters/date.html

The error is because difference in datatypes of y_pred and y_true. y_true might be dataframe and y_pred is arraylist. If you convert both to arrays, then issue will get resolved.

@gdbj's answer is a great explanation and the most up to date answer. Here's however a simpler approach.

So if you want to redirect all traffic from nginx listening to 80 to another container exposing 8080, minimum configuration can be as little as:

nginx.conf:

server {
    listen 80;

    location / {
        proxy_pass http://client:8080; # this one here
        proxy_redirect off;
    }

}

Not only Inside methods, it can be used inside classes also.

class Calculator
    {
        public static int Sum(int x,int y) => x + y;
        public static Func<int, int, int>  Add = (x, y) => x + y;
        public static Action<int,int> DisplaySum = (x, y) => Console.WriteLine(x + y);
    }

@bitestar has the correct solution, but there is one more step:

It was hidden away in the docs, however you must change the launchMode of the Activity to anything other than standard. Otherwise it will be destroyed and recreated instead of being reset to the top.

When you have the expression:

a % b = c

It really means there exists an integer n that makes c as small as possible, but non-negative.

a - n*b = c

By hand, you can just subtract 2 (or add 2 if your number is negative) over and over until the end result is the smallest positive number possible:

  3.14 % 2
= 3.14 - 1 * 2
= 1.14

Also, 3.14 % 2 * pi is interpreted as (3.14 % 2) * pi. I'm not sure if you meant to write 3.14 % (2 * pi) (in either case, the algorithm is the same. Just subtract/add until the number is as small as possible).

After some trial and tribulation, I was able to find all .msi files in a given directory and install them.

foreach($_msiFiles in 
($_msiFiles = Get-ChildItem $_Source -Recurse | Where{$_.Extension -eq ".msi"} |
 Where-Object {!($_.psiscontainter)} | Select-Object -ExpandProperty FullName)) 
{
    msiexec /i $_msiFiles /passive
}

Make sure they are both using the same interpreter. This happened to me on Ubuntu:

$ ipython3 -c 'import sys; print(sys.version)'
3.4.2 (default, Jun 19 2015, 11:34:49) \n[GCC 4.9.1]

$ python3 -c 'import sys; print(sys.version)'
3.3.0 (default, Nov 27 2012, 12:11:06) \n[GCC 4.6.3]

And sys.path was different between the two interpreters. To fix it, I removed Python 3.3.

Perhaps a better way of handling errors in MVC is to apply the HandleError attribute to your controller or action and update the Shared/Error.aspx file to do what you want. The Model object on that page includes an Exception property as well as ControllerName and ActionName.

What you are asking is pretty straight forward

1. execute query against your db to get resultset or use API to get the resultset

2. loop through the resultset or simply the result using php

3. In each iteration simply format the output as an element

if you are using the less source, there should be a variable for the navbar height in the variables.less file. If you are not using the source, then you can customize it using the customize utilty that bootstrap's site provides. And then you can downloaded it and include it in your project. The variable you are looking for is: @navbar-height

You can call window.focus();

but moving or losing the focus is bound to interfere with anyone using the tab key to get around the page.

you could listen for keycode 13, and forego the effect if the tab key is pressed.

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

Look at http://docs.oracle.com/cd/B10501_01/server.920/a96521/privs.htm#15665

Check USER_SYS_PRIVS, USER_TAB_PRIVS, USER_ROLE_PRIVS tables with these select statements

SELECT * FROM USER_SYS_PRIVS; 
SELECT * FROM USER_TAB_PRIVS; 
SELECT * FROM USER_ROLE_PRIVS;

Here, if you want to directly debug the server then you can use:

1.)Windows ->

2.)Show View -> Server: Right click on server then run In debug mode.

I do it in this way for openxlsx using following function

mywritexlsx<-function(fname="temp.xlsx",sheetname="Sheet1",data,
                  startCol = 1, startRow = 1, colNames = TRUE, rowNames = FALSE)
{
  if(! file.exists(fname))
    wb = createWorkbook()
  else
   wb <- loadWorkbook(file =fname)
  sheet = addWorksheet(wb, sheetname)

  writeData(wb,sheet,data,startCol = startCol, startRow = startRow, 
          colNames = colNames, rowNames = rowNames)
  saveWorkbook(wb, fname,overwrite = TRUE)
}

You can simply use the zoom property:

#myContainer{
    zoom: 0.5;
    -moz-transform: scale(0.5);
}

Where myContainer contains all the elements you're editing. This is supported in all major browsers.

If the compiler can do automatic type inferencing, then there wont be any issue with performance. Both of these will generate same code

var    x = new ClassA();
ClassA x = new ClassA();

however, if you are constructing the type dynamically (LINQ ...) then var is your only question and there is other mechanism to compare to in order to say what is the penalty.

@Ahmed

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close


End Sub

Try this:

function countString(str, search){
    var count=0;
    var index=str.indexOf(search);
    while(index!=-1){
        count++;
        index=str.indexOf(search,index+1);
    }
    return count;
}

Here is how I did it using ASP classic and couldn't quite get it to work with the answers above and I wanted to be able to copy a product in our system to a new product_id and needed it to be able to work even when we add in more columns to the table.

Cn.Execute("CREATE TEMPORARY TABLE temprow AS SELECT * FROM product WHERE product_id = '12345'")
Cn.Execute("UPDATE temprow SET product_id = '34567'")
Cn.Execute("INSERT INTO product SELECT * FROM temprow")
Cn.Execute("DELETE temprow")
Cn.Execute("DROP TABLE temprow")

px ? Pixels

All of these answers seem to be incorrect. Contrary to intuition, in CSS the px is not pixels. At least, not in the simple physical sense.

Read this article from the W3C, EM, PX, PT, CM, IN…, about how px is a "magical" unit invented for CSS. The meaning of px varies by hardware and resolution. (That article is fresh, last updated 2014-10.)

My own way of thinking about it: 1 px is the size of a thin line intended by a designer to be barely visible.

To quote that article:

The px unit is the magic unit of CSS. It is not related to the current font and also not related to the absolute units. The px unit is defined to be small but visible, and such that a horizontal 1px wide line can be displayed with sharp edges (no anti-aliasing). What is sharp, small and visible depends on the device and the way it is used: do you hold it close to your eyes, like a mobile phone, at arms length, like a computer monitor, or somewhere in between, like a book? The px is thus not defined as a constant length, but as something that depends on the type of device and its typical use.

To get an idea of the appearance of a px, imagine a CRT computer monitor from the 1990s: the smallest dot it can display measures about 1/100th of an inch (0.25mm) or a little more. The px unit got its name from those screen pixels.

Nowadays there are devices that could in principle display smaller sharp dots (although you might need a magnifier to see them). But documents from the last century that used px in CSS still look the same, no matter what the device. Printers, especially, can display sharp lines with much smaller details than 1px, but even on printers, a 1px line looks very much the same as it would look on a computer monitor. Devices change, but the px always has the same visual appearance.

That article gives some guidance about using pt vs px vs em, to answer this Question.

You can use matplotlib for this. matplotlib has a mplot3d module that will do exactly what you want.

from matplotlib import pyplot
from mpl_toolkits.mplot3d import Axes3D
import random


fig = pyplot.figure()
ax = Axes3D(fig)

sequence_containing_x_vals = list(range(0, 100))
sequence_containing_y_vals = list(range(0, 100))
sequence_containing_z_vals = list(range(0, 100))

random.shuffle(sequence_containing_x_vals)
random.shuffle(sequence_containing_y_vals)
random.shuffle(sequence_containing_z_vals)

ax.scatter(sequence_containing_x_vals, sequence_containing_y_vals, sequence_containing_z_vals)
pyplot.show()

The code above generates a figure like:

You must use $rootScope to send and capture events between controllers in same app. Inject $rootScope dependency to your controllers. Here is a working example.

app.controller('firstCtrl', function($scope, $rootScope) {        
        function firstCtrl($scope) {
        {
            $rootScope.$emit('someEvent', [1,2,3]);
        }
}

app.controller('secondCtrl', function($scope, $rootScope) {
        function secondCtrl($scope)
        {
            $rootScope.$on('someEvent', function(event, data) { console.log(data); });
        }
}

Events linked into $scope object just work in the owner controller. Communication between controllers is done via $rootScope or Services.

I haven't timed it but I suspect this would be pretty quick:

import numpy as np
list1=[1, 2, 3]
list2=[4, 5, 6]

list_sum = (np.add(list1, list2)).tolist()

[5, 7, 9]

For the Javadoc tag @see, you don't need to use @link; Javadoc will create a link for you. Try

To expound on Douwem's answer, in your script tag, put your code in an onload:

</script>

Tested with Angular2 RC2

I tried a code-snippet similar to yours and it works for me ;) see [(ngModel)] = "str" in my template If you push the button, the console logs the current content of the textarea-field. Hope it helps

textarea-component.ts

import {Component} from '@angular/core';

@Component({
  selector: 'textarea-comp',
  template: `
      <textarea cols="30" rows="4" [(ngModel)] = "str"></textarea>
      <p><button (click)="pushMe()">pushMeToLog</button></p>
  `
})

  export class TextAreaComponent {
    str: string;

  pushMe() {
      console.log( "TextAreaComponent::str: " + this.str);
  }
}

$query="SELECT * FROM contacts";
$result=mysql_query($query);

In order to see the changes that have been staged already, you can pass the -–staged option to git diff (in pre-1.6 versions of Git, use –-cached).

git diff --staged
git diff --cached

An elegant way to move your file to an nonexistent directory is to create the following extension to native FileInfo class:

public static class FileInfoExtension
{
    //second parameter is need to avoid collision with native MoveTo
    public static void MoveTo(this FileInfo file, string destination, bool autoCreateDirectory) { 

        if (autoCreateDirectory)
        {
            var destinationDirectory = new DirectoryInfo(Path.GetDirectoryName(destination));

            if (!destinationDirectory.Exists)
                destinationDirectory.Create();
        }

        file.MoveTo(destination);
    }
}

Then use brand new MoveTo extension:

 using <namespace of FileInfoExtension>;
 ...
 new FileInfo("some path")
     .MoveTo("target path",true);

Check Methods extension documentation.

No need to uninstall angular/cli.

1. You just need to make sure the PATH to npm is in your environment PATH and at the top.

C:\Users\yourusername\AppData\Roaming\npm

2. Then close whatever git or command client your using and run ng-v again and should work

Try docker rmi node. That should work.

Seeing all created containers is as simple as docker ps -a.

To remove all existing containers (not images!) run docker rm $(docker ps -aq)

No, nothing built-in. Do it yourself:

• Instantiate a Scripting.Dictionary object
• Write a For loop over your array (be sure to use LBound() and UBound() instead of looping from 0 to x!)
• On each iteration, check Exists() on the dictionary. Add every array value (that doesn't already exist) as a key to the dictionary (use CStr() since keys must be strings as I've just learned, keys can be of any type in a Scripting.Dictionary), also store the array value itself into the dictionary.
• When done, use Keys() (or Items()) to return all values of the dictionary as a new, now unique array.
• In my tests, the Dictionary keeps original order of all added values, so the output will be ordered like the input was. I'm not sure if this is documented and reliable behavior, though.

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

Yes this is happening because you are accessing mi variable from within your anonymous inner class, what happens deep inside is that another copy of your variable is created and will be use inside the anonymous inner class, so for data consistency the compiler will try restrict you from changing the value of mi so that's why its telling you to set it to final.

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

How about setInterval, to check for complete iteration count, brings guarantee. not sure if it won't overload the scope though but I use it and seems to be the one

_.forEach(actual_JSON, function (key, value) {

     // run any action and push with each iteration 

     array.push(response.id)

});


setInterval(function(){

    if(array.length > 300) {

        callback()

    }

}, 100);

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

I try to make the code a little bit understandable by naming the variables, I hope this can help

function getDistanceFromLatLonInKm(point1, point2) {

  const [lat1, lon1] = point1;
  const [lat2, lon2] = point2;
  const earthRadius = 6371;
  const dLat = convertDegToRad(lat2 - lat1);
  const dLon = convertDegToRad(lon2 - lon1);
  const squarehalfChordLength =
    Math.sin(dLat / 2) * Math.sin(dLat / 2) +
    Math.cos(convertDegToRad(lat1)) * Math.cos(convertDegToRad(lat2)) *
    Math.sin(dLon / 2) * Math.sin(dLon / 2);

  const angularDistance = 2 * Math.atan2(Math.sqrt(squarehalfChordLength), Math.sqrt(1 - squarehalfChordLength));
  const distance = earthRadius * angularDistance;
  return distance;

}

Well, how about this !!

This code calculates both row and column count in a csv file. Try this out !!

    static int[] getRowsColsNo() {
    Scanner scanIn = null;
    int rows = 0;
    int cols = 0;
    String InputLine = "";
    try {
        scanIn = new Scanner(new BufferedReader(
                new FileReader("filename.csv")));
        scanIn.useDelimiter(",");
        while (scanIn.hasNextLine()) {
            InputLine = scanIn.nextLine();
            String[] InArray = InputLine.split(",");
            rows++;
            cols = InArray.length;
        }

    } catch (Exception e) {
        System.out.println(e);
    }
    return new int[] { rows, cols };
}

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

The method GetFileNameWithoutExtension, as the name implies, does not return the extension on the file. In your case, it would only return "a". You want to append your ".Jpeg" to that result. However, at a different level, this seems strange, as image files have different metadata and cannot be converted so easily.

The answer of Steve is correct, but it doesn't work for integers less than 1.

Here an updated version that does work for negatives:

int digits = n == 0 ? 1 : Math.Floor(Math.Log10(Math.Abs(n)) + 1)

There are some very important benefits to the use of const and some would say it should be used wherever possible because of how deliberate and indicative it is.

It is, as far as I can tell, the most indicative and predictable declaration of variables in JavaScript, and one of the most useful, BECAUSE of how constrained it is. Why? Because it eliminates some possibilities available to var and let declarations.

What can you infer when you read a const? You know all of the following just by reading the const declaration statement, AND without scanning for other references to that variable:

• the value is bound to that variable (although its underlying object is not deeply immutable)
• it can’t be accessed outside of its immediately containing block
• the binding is never accessed before declaration, because of Temporal Dead Zone (TDZ) rules.

The following quote is from an article arguing the benefits of let and const. It also more directly answers your question about the keyword's constraints/limits:

Constraints such as those offered by let and const are a powerful way of making code easier to understand. Try to accrue as many of these constraints as possible in the code you write. The more declarative constraints that limit what a piece of code could mean, the easier and faster it is for humans to read, parse, and understand a piece of code in the future.

Granted, there’s more rules to a const declaration than to a var declaration: block-scoped, TDZ, assign at declaration, no reassignment. Whereas var statements only signal function scoping. Rule-counting, however, doesn’t offer a lot of insight. It is better to weigh these rules in terms of complexity: does the rule add or subtract complexity? In the case of const, block scoping means a narrower scope than function scoping, TDZ means that we don’t need to scan the scope backwards from the declaration in order to spot usage before declaration, and assignment rules mean that the binding will always preserve the same reference.

The more constrained statements are, the simpler a piece of code becomes. As we add constraints to what a statement might mean, code becomes less unpredictable. This is one of the biggest reasons why statically typed programs are generally easier to read than dynamically typed ones. Static typing places a big constraint on the program writer, but it also places a big constraint on how the program can be interpreted, making its code easier to understand.

With these arguments in mind, it is recommended that you use const where possible, as it’s the statement that gives us the least possibilities to think about.

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

There's also AppGyver Steroids that unites PhoneGap and Native UI nicely.

With Steroids you can add things like native tabs, native navigation bar, native animations and transitions, native modal windows, native drawer/panel (facebooks side menu) etc. to your PhoneGap app.

Here's a demo: http://youtu.be/oXWwDMdoTCk?t=20m17s

tl;dr

20:11:13 < 01:00:00 < 14:49:00

LocalTime target = LocalTime.parse( "01:00:00" ) ;
Boolean targetInZone = ( 
    target.isAfter( LocalTime.parse( "20:11:13" ) ) 
    && 
    target.isBefore( LocalTime.parse( "14:49:00" ) ) 
) ; 

java.time.LocalTime

The java.time classes include LocalTime to represent a time-of-day only without a date and without a time zone.

So what I want is, 20:11:13 < 01:00:00 < 14:49:00.

First we define the boundaries. Your input strings happen to comply with standard ISO 8601 formats. The java.time classes use ISO 8601 formats by default, so no need to specify a formatting pattern.

LocalTime start = LocalTime.parse( "20:11:13" );
LocalTime stop = LocalTime.parse( "14:49:00" );

And define our test case, the target 01:00:00.

LocalTime target = LocalTime.parse( "01:00:00" );

Now we are set up to compare these LocalTime objects. We want to see if the target is after the later time but before the earlier time. That means middle of the night in this case, between approximately 8 PM and 3 AM the next morning.

Boolean isTargetAfterStartAndBeforeStop = ( target.isAfter( start ) && target.isBefore( stop ) ) ;

That test can be more simply stated as “not between 3 AM and 8 PM”. We could then generalize to any pair of LocalTime objects where we test for between if the start comes before the stop with a 24-hour clock, and not between if start comes after the stop (as in the case of this Question).

Further more, spans of time are usually handled with the Half-Open approach where the beginning is inclusive while the ending is exclusive. So a "between" comparison, strictly speaking, would be “is the target equal to or later than start AND the target is before stop”, or more simply, “is target not before start AND before stop”.

Boolean isBetweenStartAndStopStrictlySpeaking = 
    ( ( ! target.isBefore( start ) && target.isBefore( stop ) ) ;

If the start is after the stop, within a 24-hour clock, then assume we want the logic suggested in the Question (is after 8 PM but before 3 AM).

if( start.isAfter( stop ) ) {
    return ! isBetweenStartAndStopStrictlySpeaking ;
} else {
    return isBetweenStartAndStopStrictlySpeaking ;
}

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

I'm not sure about more efficient in terms of big-O but certainly using the unshift method is more concise:

var a = [1, 2, 3, 4];
a.unshift(0);
a; // => [0, 1, 2, 3, 4]

[Edit]

This jsPerf benchmark shows that unshift is decently faster in at least a couple of browsers, regardless of possibly different big-O performance if you are ok with modifying the array in-place. If you really can't mutate the original array then you would do something like the below snippet, which doesn't seem to be appreciably faster than your solution:

a.slice().unshift(0); // Use "slice" to avoid mutating "a".

[Edit 2]

For completeness, the following function can be used instead of OP's example prependArray(...) to take advantage of the Array unshift(...) method:

function prepend(value, array) {
  var newArray = array.slice();
  newArray.unshift(value);
  return newArray;
}

var x = [1, 2, 3];
var y = prepend(0, x);
y; // => [0, 1, 2, 3];
x; // => [1, 2, 3];

This worked for me

.form-control {
box-shadow: none!important;}

+new is equivalent to +alloc/-init in Apple's NSObject implementation. It is highly unlikely that this will ever change, but depending on your paranoia level, Apple's documentation for +new appears to allow for a change of implementation (and breaking the equivalency) in the future. For this reason, because "explicit is better than implicit" and for historical continuity, the Objective-C community generally avoids +new. You can, however, usually spot the recent Java comers to Objective-C by their dogged use of +new.

Any Reference to 'Row' should use 'long' not 'integer' else it will overflow if the spreadsheet has a lot of data.

Swift 3:

String(data: data, encoding: .utf8)

You can set a control variable in vars files located in group_vars/ or directly in hosts file like this:

[vagrant:vars]
test_var=true

[location-1]
192.168.33.10 hostname=apollo

[location-2]
192.168.33.20 hostname=zeus

[vagrant:children]
location-1
location-2

And run tasks like this:

- name: "test"
  command: "echo {{test_var}}"
  when: test_var is defined and test_var

Does the screenshot contain only the icon? If so, the L2 distance of the two images might suffice. If the L2 distance doesn't work, the next step is to try something simple and well established, like: Lucas-Kanade. Which I'm sure is available in OpenCV.

This article on CodeProject details a technique. Is basically boils down to:

This essentially does exactly the same as grabbing the title bar of a window, from the window manager's point of view.

    int         width  = img.getWidth();
    int         height = img.getHeight();
    BufferedImage   newImage = new BufferedImage( height, width, img.getType() );

    for( int i=0 ; i < width ; i++ )
        for( int j=0 ; j < height ; j++ )
            newImage.setRGB( height-1-j, i, img.getRGB(i,j) );

    return newImage;
}

A great way of handling this is with regular expressions.

string modifiedString = Regex.Replace(originalString, @"(\r\n)|\n|\r", "<br/>");

This will replace any of the 3 legal types of newline with the html tag.

In short:

import matplotlib.dates as mdates
myFmt = mdates.DateFormatter('%d')
ax.xaxis.set_major_formatter(myFmt)

Many examples on the matplotlib website. The one I most commonly use is here

in below code midpointsList is an ArrayList of waypoints

private String getMapsApiDirectionsUrl(GoogleMap googleMap, LatLng startLatLng, LatLng endLatLng, ArrayList<LatLng> midpointsList) {
    String origin = "origin=" + startLatLng.latitude + "," + startLatLng.longitude;

    String midpoints = "";
    for (int mid = 0; mid < midpointsList.size(); mid++) {
        midpoints += "|" + midpointsList.get(mid).latitude + "," + midpointsList.get(mid).longitude;
    }

    String waypoints = "waypoints=optimize:true" + midpoints + "|";

    String destination = "destination=" + endLatLng.latitude + "," + endLatLng.longitude;
    String key = "key=AIzaSyCV1sOa_7vASRBs6S3S6t1KofFvDhjohvI";

    String sensor = "sensor=false";
    String params = origin + "&" + waypoints + "&" + destination + "&" + sensor + "&" + key;
    String output = "json";
    String url = "https://maps.googleapis.com/maps/api/directions/" + output + "?" + params;


    Log.e("url", url);
    parseDirectionApidata(url, googleMap);
    return url;
}

Then copy and paste this url in your browser to check And the below code is to parse the url

    private void parseDirectionApidata(String url, final GoogleMap googleMap) {

    final JSONObject jsonObject = new JSONObject();

    try {

        AppUtill.getJsonWithHTTPPost(ViewMapActivity.this, 1, new ServiceCallBack() {
            @Override
            public void serviceCallBack(int id, JSONObject jsonResult) throws JSONException {

                if (jsonResult != null) {

                    Log.e("jsonRes", jsonResult.toString());

                    String status = jsonResult.optString("status");

                    if (status.equalsIgnoreCase("ok")) {
                        drawPath(jsonResult, googleMap);
                    }

                } else {

                    Toast.makeText(ViewMapActivity.this, "Unable to parse Directions Data", Toast.LENGTH_LONG).show();
                }

            }
        }, url, jsonObject);

    } catch (Exception e) {
        e.printStackTrace();

    }
}

And then pass the result to the drawPath method

    public void drawPath(JSONObject jObject, GoogleMap googleMap) {

    List<List<HashMap<String, String>>> routes = new ArrayList<List<HashMap<String, String>>>();
    JSONArray jRoutes = null;
    JSONArray jLegs = null;
    JSONArray jSteps = null;

    try {

        Toast.makeText(ViewMapActivity.this, "Drawing Path...", Toast.LENGTH_SHORT).show();
        jRoutes = jObject.getJSONArray("routes");

        /** Traversing all routes */
        for (int i = 0; i < jRoutes.length(); i++) {
            jLegs = ((JSONObject) jRoutes.get(i)).getJSONArray("legs");
            List path = new ArrayList<HashMap<String, String>>();

            /** Traversing all legs */
            for (int j = 0; j < jLegs.length(); j++) {
                jSteps = ((JSONObject) jLegs.get(j)).getJSONArray("steps");

                /** Traversing all steps */
                for (int k = 0; k < jSteps.length(); k++) {
                    String polyline = "";
                    polyline = (String) ((JSONObject) ((JSONObject) jSteps.get(k)).get("polyline")).get("points");
                    list = decodePoly(polyline);
                }
                Log.e("list", list.toString());
                routes.add(path);
                Log.e("routes", routes.toString());
                if (list != null) {
                    Polyline line = googleMap.addPolyline(new PolylineOptions()
                            .addAll(list)
                            .width(12)

                    );
                }
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

}

  private List<LatLng> decodePoly(String encoded) {

    List<LatLng> poly = new ArrayList<LatLng>();
    int index = 0, len = encoded.length();
    int lat = 0, lng = 0;

    while (index < len) {
        int b, shift = 0, result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lat += dlat;

        shift = 0;
        result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lng += dlng;

        LatLng p = new LatLng((((double) lat / 1E5)),
                (((double) lng / 1E5)));
        poly.add(p);
    }

    return poly;
}

decode poly function is to decode the points(lat and long) provided by Directions API in encoded form

How about a shorthand notation?

{overflow: auto hidden;}

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

It can be because you have jpa dependendencies and plugins...

just comment it if not use(build.gradle or pom file)

e. g.

// kotlin("plugin.jpa") version "1.3.61"

// implementation("org.springframework.boot:spring-boot-starter-data-jpa")

If you are using fastexml jackson, you can use the following: com.fasterxml.jackson.core.io.JsonStringEncoder.getInstance().quoteAsString(input)

If you are using codehaus jackson, you can use the following: org.codehaus.jackson.io.JsonStringEncoder.getInstance().quoteAsString(input)

You can find more info about what limitations browsers will likely add to mitigate this and what IETF is doing about it as well as why this is needed at IETF SPEC on IP handling

There could be different reasons why it doesn't work for you: perhaps you need to qualify the name with std::, or perhaps you do not have C++11 support.

This works, provided you have C++11 support:

#include <string>

int main()
{
  std::string s = std::to_string(42);
}

To enable C++11 support with g++ or clang, you need to pass the option -std=c++0x. You can also use -std=c++11 on the newer versions of those compilers.

Alternatively you can use a "." instead of *, as this will take all the files in the working directory, include the folders and subfolders:

FROM ubuntu
COPY . /
RUN ls -la /

This is what I'm using.

module.exports.getBookByName = function(name,callback){
    var query = {
            name: {$regex : name}
    }
    User.find(query,callback);
}

Type

chcp

to see your current code page (as Dewfy already said).

Use

nlsinfo

to see all installed code pages and find out what your code page number means.

You need to have Windows Server 2003 Resource kit installed (works on Windows XP) to use nlsinfo.

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

It depends on how you want to use your String. This can help:

String total =  Integer.toString(123) + Double.toString(456.789);

A simple method along the lines of:

bool AreAllColumnsEmpty(DataRow dr)
{
 if (dr == null)
 {
  return true;
 }
 else
 {
  foreach(var value in dr.ItemArray)
  {
    if (value != null)
    {
      return false;
    }
  }
  return true;
 }
}

Should give you what you're after, and to make it "nice" (as there's nothing as far as I'm aware, in the Framework), you could wrap it up as an extension method, and then your resultant code would be:

if (datarow.AreAllColumnsEmpty())
{
}
else
{
}

Cross browser way of doing this is

var top = ($(window).scrollTop() || $("body").scrollTop());

Using global variables is kind of like sweeping dirt under a rug. It's a quick fix, and a lot easier in the short term than getting a dust-pan or vacuum to clean it up. However, if you ever end up moving the rug later, you're gonna have a big surprise mess underneath.

In case someone stumbled upon this problem when working on Grails (or pure Spring) web application, here is the post that helped me:

http://forum.spring.io/forum/spring-projects/web/2491-solved-character-encoding-and-multipart-forms

To set default encoding to UTF-8 (instead of the ISO-8859-1) for multipart requests, I added the following code in resources.groovy (Spring DSL):

multipartResolver(ContentLengthAwareCommonsMultipartResolver) {
    defaultEncoding = 'UTF-8'
}

You can easily obtain Right() and Left() functions starting from the Rbase package:

• right function

  right = function (string, char) {
      substr(string,nchar(string)-(char-1),nchar(string))
  }
  

• left function

  left = function (string,char) {
      substr(string,1,char)
  }
  

you can use those two custom-functions exactly as left() and right() in excel. Hope you will find it useful

clean is its own build lifecycle phase (which can be thought of as an action or task) in Maven. mvn clean install tells Maven to do the clean phase in each module before running the install phase for each module.

What this does is clear any compiled files you have, making sure that you're really compiling each module from scratch.

I often use something similar to this:

import os
DATA_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__), 'datadir'))

# if you have more paths to set, you might want to shorten this as
here = lambda x: os.path.abspath(os.path.join(os.path.dirname(__file__), x))
DATA_DIR = here('datadir') 

pathjoin = os.path.join
# ...
# later in script
for fn in os.listdir(DATA_DIR):
    f = open(pathjoin(DATA_DIR, fn))
    # ...

The variable

__file__

holds the file name of the script you write that code in, so you can make paths relative to script, but still written with absolute paths. It works quite well for several reasons:

• path is absolute, but still relative
• the project can still be deployed in a relative container

But you need to watch for platform compatibility - Windows' os.pathsep is different than UNIX.

Check the domain's web server for http://www.<domain>.com configuration for X-Frame-Options It is a security feature designed to prevent clickJacking attacks,

How Does clickJacking work?

1. The evil page looks exactly like the victim page.
2. Then it tricked users to enter their username and password.

Technically the evil has an iframe with the source to the victim page.

<html>
    <iframe src='victim_domain.com'/>
    <input id="username" type="text" style="display: none;"/>
    <input id="password" type="text" style="display: none;"/>
    <script>
        //some JS code that click jacking the user username and input from inside the iframe...
    <script/>
<html>

How the security feature work

If you want to prevent web server request to be rendered within an iframe add the x-frame-options

X-Frame-Options DENY

The options are:

1. SAMEORIGIN //allow only to my own domain render my HTML inside an iframe.
2. DENY //do not allow my HTML to be rendered inside any iframe
3. "ALLOW-FROM https://example.com/" //allow specific domain to render my HTML inside an iframe

This is IIS config example:

   <httpProtocol>
       <customHeaders>
           <add name="X-Frame-Options" value="SAMEORIGIN" />
       </customHeaders>
   </httpProtocol>

The solution to the question

If the web server activated the security feature it may cause a client-side SecurityError as it should.

With files we know the size in advance, so just read it all at once!

String result;
File file = ...;

long length = file.length();
if (length < 1 || length > Integer.MAX_VALUE) {
    result = "";
    Log.w(TAG, "File is empty or huge: " + file);
} else {
    try (FileReader in = new FileReader(file)) {
        char[] content = new char[(int)length];

        int numRead = in.read(content);
        if (numRead != length) {
            Log.e(TAG, "Incomplete read of " + file + ". Read chars " + numRead + " of " + length);
        }
        result = new String(content, 0, numRead);
    }
    catch (Exception ex) {
        Log.e(TAG, "Failure reading " + this.file, ex);
        result = "";
    }
}

A cursor will only accept a select statement, so if the SQL really needs to be dynamic make the declare cursor part of the statement you are executing. For the below to work your server will have to be using global cursors.

Declare @UserID varchar(100)
declare @sqlstatement nvarchar(4000)
--move declare cursor into sql to be executed
set @sqlstatement = 'Declare  users_cursor CURSOR FOR SELECT userId FROM users'

exec sp_executesql @sqlstatement


OPEN users_cursor
FETCH NEXT FROM users_cursor
INTO @UserId

WHILE @@FETCH_STATUS = 0
BEGIN
Print @UserID
EXEC asp_DoSomethingStoredProc @UserId

FETCH NEXT FROM users_cursor --have to fetch again within loop
INTO @UserId

END
CLOSE users_cursor
DEALLOCATE users_cursor

If you need to avoid using the global cursors, you could also insert the results of your dynamic SQL into a temporary table, and then use that table to populate your cursor.

Declare @UserID varchar(100)
create table #users (UserID varchar(100))

declare @sqlstatement nvarchar(4000)
set @sqlstatement = 'Insert into #users (userID) SELECT userId FROM users'
exec(@sqlstatement)

declare users_cursor cursor for Select UserId from #Users
OPEN users_cursor
FETCH NEXT FROM users_cursor
INTO @UserId

WHILE @@FETCH_STATUS = 0
BEGIN

EXEC asp_DoSomethingStoredProc @UserId

FETCH NEXT FROM users_cursor
INTO @UserId

END
CLOSE users_cursor
DEALLOCATE users_cursor

drop table #users

Hope it's working for you

 function GetSelectedItem()
 {
     var index = document.getElementById(select1).selectedIndex;

 }

I am using this to switch one branch to another anyone you can use it works for me like charm.

git switch [branchName] OR git checkout [branchName]

ex: git switch develop OR
git checkout develop

You can easily get data from another table. You have to add fields only you want.

The mysql query is:

INSERT INTO table_name1(fields you want)
  SELECT fields you want FROM table_name2

where, the values are copied from table2 to table1

The code below works for trusting self-signed certificates. You have to use the TrustSelfSignedStrategy when creating your client:

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        builder.build());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
        sslsf).build();

HttpGet httpGet = new HttpGet("https://some-server");
CloseableHttpResponse response = httpclient.execute(httpGet);
try {
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
} finally {
    response.close();
}

I did not include the SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER on purpose: The point was to allow testing with self signed certificates so you don't have to acquire a proper certificate from a certification authority. You can easily create a self-signed certificate with the correct host name, so do that instead of adding the SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER flag.

I think this say it all:

this alternative syntax is excellent for improving legibility (for both PHP and HTML!) in situations where you have a mix of them.

http://ca3.php.net/manual/en/control-structures.alternative-syntax.php

When mixing HTML an PHP the alternative sytnax is much easier to read. In normal PHP documents the traditional syntax should be used.

I encountered this issue because I used setState instead of state in the constructor.

EXAMPLE

Change the following incorrect code

constructor(props) {
  super(props);
  this.setState({
    key: ''
  });
}

to

constructor(props) {
  super(props);
  this.state = {
    key: ''
  }; 
}

See the scipy.interpolate documentation for some examples.

The following example demonstrates its use, for linear and cubic spline interpolation:

>>> from scipy.interpolate import interp1d

>>> x = np.linspace(0, 10, num=11, endpoint=True)
>>> y = np.cos(-x**2/9.0)
>>> f = interp1d(x, y)
>>> f2 = interp1d(x, y, kind='cubic')

>>> xnew = np.linspace(0, 10, num=41, endpoint=True)
>>> import matplotlib.pyplot as plt
>>> plt.plot(x, y, 'o', xnew, f(xnew), '-', xnew, f2(xnew), '--')
>>> plt.legend(['data', 'linear', 'cubic'], loc='best')
>>> plt.show()

Simply simulate a click on the <input> by using the trigger() function when clicking on a styled <div>. I created my own button out of a <div> and then triggered a click on the input when clicking my <div>. This allows you to create your button however you want because it's a <div> and simulates a click on your file <input>. Then use display: none on your <input>.

// div styled as my load file button
<div id="simClick">Load from backup</div>

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

// Click function for input
$("#readFile").click(function() {
    readFile();
});

// Simulate click on the input when clicking div
$("#simClick").click(function() {
    $("#readFile").trigger("click");
});

How do you send the message?

The classes in the System.Net.Mail namespace (which is probably what you should use) has full support for authentication, either specified in Web.config, or using the SmtpClient.Credentials property.

 string path= @"C:\Users\username\Desktop\FolderName"
  string Dirctory = new FileInfo(path).Name.ToString();
//output FolderName

There is a very simple and easy solution to your question:

var districtId = 210;

if (DistrictsEnum[districtId] != null) {

// Returns 'undefined' if the districtId not exists in the DistrictsEnum 
    model.handlingDistrictId = districtId;
}

To delete folder having files, no need of loops or recursive search. You can directly use:

FileUtils.deleteDirectory(<File object of directory>);

This function will directory delete the folder and all files in it.

Here you can find a working example, with some more suggestions about dynamic resizing of the list.

I've used display:inline-block and a percentage padding so that the parent list can dynamically change size:
