If you need access to the index as you iterate through the string, use enumerate():

>>> for i, c in enumerate('test'):
...     print i, c
... 
0 t
1 e
2 s
3 t

use directly where you want controller or web.php

Request::getHost();

Change

$info=$_POST['id[]'];

to

$info=$_POST['id'];

by adding [] to the end of your form field names, PHP will automatically convert these variables into arrays.

Answering my own question here... turns out it's a Windows only quirk that happens when reading binary files (in my case a JPEG) that requires an additional flag in the open or File.open function call. I revised it to open("/path/to/file", 'rb') {|io| a = a + io.read} and all was fine.

If multiple criteria use countifs

=countifs(A1:A10,">""",B1:B10,">""")

The " >"" " looks at the greater than being empty. This formula looks for two criteria and neither column can be empty on the same row for it to count. If just counting one column do this with the one criteria (i.e. Use everything before B1:B10 not including the comma)

you can start with this tool, https://themestr.app/theme , seeing how it overwrites the scss variables, you would get an idea what variable impacts what. its the simplest way I think.

example scss genearation:

@import url(https://fonts.googleapis.com/css?family=Montserrat:200,300,400,700);
$font-family-base:Montserrat;
@import url(https://fonts.googleapis.com/css?family=Open+Sans:200,300,400,700);
$headings-font-family:Open Sans;

$enable-grid-classes:false;
$primary:#222222;
$secondary:#666666;
$success:#333333;
$danger:#434343;
$info:#515151;
$warning:#5f5f5f;
$light:#eceeec;
$dark:#111111;
@import "bootstrap";

look it this piece of code from my project

I'm trying to re-order the list based on a property inside my model,

 allEmployees = new List<Employee>(allEmployees.OrderByDescending(employee => employee.Name));

but I faced a problem when a small and capital letters exist, so to solve it, I used the string comparer.

allEmployees.OrderBy(employee => employee.Name,StringComparer.CurrentCultureIgnoreCase)

Its much easier than all this: Simply transition the same property on your element

.earth { width:  0.92%;    transition: width 1s;  }
.earth:hover { width: 50%; transition: width 1s;  }

The reason is that CTAS (Create table as select) does not copy any metadata from the source to the target table, namely

• no primary key
• no foreign keys
• no grants
• no indexes
• ...

To achieve what you want, I'd either

• use dbms_metadata.get_ddl to get the complete table structure, replace the table name with the new name, execute this statement, and do an INSERT afterward to copy the data
• or keep using CTAS, extract the not null constraints for the source table from user_constraints and add them to the target table afterwards

finalize will print out the count for class creation.

protected void finalize() throws Throwable {
    System.out.println("Run F" );
    if ( checkedOut)
        System.out.println("Error: Checked out");
        System.out.println("Class Create Count: " + classCreate);
}

main

while ( true) {
    Book novel=new Book(true);
    //System.out.println(novel.checkedOut);
    //Runtime.getRuntime().runFinalization();
    novel.checkIn();
    new Book(true);
    //System.runFinalization();
    System.gc();

As you can see. The following out put show the gc got executed first time when the class count is 36.

C:\javaCode\firstClass>java TerminationCondition
Run F
Error: Checked out
Class Create Count: 36
Run F
Error: Checked out
Class Create Count: 48
Run F

There's a much easier approach using PrintWriter (see here)

Basically all you need is:

// set up URL connection
URL urlToRequest = new URL(urlStr);
HttpURLConnection urlConnection = (HttpURLConnection)urlToRequest.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

// write out form parameters
String postParamaters = "param1=value1&param2=value2"
urlConnection.setFixedLengthStreamingMode(postParameters.getBytes().length);
PrintWriter out = new PrintWriter(urlConnection.getOutputStream());
out.print(postParameters);
out.close();

// connect
urlConnection.connect();

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

If you are using a "Standard TCP/IP over SSH" type of connection, under "Preferences"->"Others" there is "SSH KeepAlive" field. It took me quite a while to find it :(

Didier have a tool to parse the PDF:

.Net Core seems to be missing the DispatcherTimer.

If we are OK with using an async method, Task.Delay will meet our needs. This can also be useful if you want to wait inside of a for loop for rate-limiting reasons.

public async Task DoTasks(List<Items> items)
{
    foreach (var item in items)
    {
        await Task.Delay(2 * 1000);
        DoWork(item);
    }
}

You can await the completion of this method as follows:

public async void TaskCaller(List<Item> items)
{
    await DoTasks(items);
}

Sorry but that's just much too much overhead (above), short and quick, if you have the MapFragment, you also have to map, just do the following:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            googleMap.setMyLocationEnabled(true)
} else {
    // Show rationale and request permission.
}

Code is in Kotlin, hope you don't mind.

have fun

Btw I think this one is a duplicate of: Show Current Location inside Google Map Fragment

There may be several reasons Java does not generally use the IUser convention.

1. Part of the Object-Oriented approach is that you should not have to know whether the client is using an interface or an implementation class. So, even List is an interface and String is an actual class, a method might be passed both of them - it doesn't make sense to visually distinguish the interfaces.

2. In general, we will actually prefer the use of interfaces in client code (prefer List to ArrayList, for instance). So it doesn't make sense to make the interfaces stand out as exceptions.

3. The Java naming convention prefers longer names with actual meanings to Hungarian-style prefixes. So that code will be as readable as possible: a List represents a list, and a User represents a user - not an IUser.

After some tries, these are the samples I am using in order to connect:

Specifying the username and the password:

sqlcmd -S 211.11.111.111 -U NotSA -P NotTheSaPassword

Specifying the DB as well:

sqlcmd -S 211.11.111.111 -d SomeSpecificDatabase -U NotSA -P NotTheSaPassword

if you check for the element type

type(countries[1])

the result will be <class float> so you can use the following code:

[i for i in countries if type(i) is not float]

In this simple case, where someClass.f is not inheriting any data from the class and not attaching anything to the class, a possible solution would be to separate out f, so it can be pickled:

import multiprocessing


def f(x):
    return x*x


class someClass(object):
    def __init__(self):
        pass

    def go(self):
        pool = multiprocessing.Pool(processes=4)       
        print pool.map(f, range(10))

When the user presses the tab button the user will be taken through the form in the order 1, 2, and 3 as indicated in the example below.

For example:

Name: <input name="name" tabindex="1"  />
Age: <input name="age" tabindex="3"  />
Email: <input name="email" tabindex="2"  />

You are using an old version of the date picker js. Upgrade datepicker js with latest one.

Replace your bootstrap-datetimepicker.min.js file with this will work..

<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/3.1.3/js/bootstrap-datetimepicker.min.js"></script>

I would use the second method as it is more explicit. Otherwise you don't know where the variables are coming from.

Why do you need to check both GET and POST anyway? Surely using one or the other only makes more sense.

Just try this code this code work with me

var posOptions = {timeout: 10000, enableHighAccuracy: false};
$cordovaGeolocation.getCurrentPosition(posOptions).then(function (position) {
var lat = position.coords.latitude;
var long = position.coords.longitude;
 //console.log(lat +"          "+long);
$http.get('https://maps.googleapis.com/maps/api/geocode/json?latlng=' + lat + ',' + long + '&key=your key here').success(function (output) {
//console.log( JSON.stringify(output.results[0]));
//console.log( JSON.stringify(output.results[0].address_components[4].short_name));
var results = output.results;
if (results[0]) {
//console.log("results.length= "+results.length);
//console.log("hi "+JSON.stringify(results[0],null,4));
for (var j = 0; j < results.length; j++){
 //console.log("j= "+j);
//console.log(JSON.stringify(results[j],null,4));
for (var i = 0; i < results[j].address_components.length; i++){
 if(results[j].address_components[i].types[0] == "country") {
 //this is the object you are looking for
  country = results[j].address_components[i];
 }
 }
 }
 console.log(country.long_name);
 console.log(country.short_name);
 } else {
 alert("No results found");
 console.log("No results found");
 }
 });
 }, function (err) {
 });

The short answer is that setting grid-auto-rows: 1fr; on the grid container solves what was asked.

I found an a bit different solution of my problem regarding this context. Thought worth sharing.

Most of the example create readStreams from file. But in my case readStream has to be created from JSON string coming from a message pool.

var jsonStream = through2.obj(function(chunk, encoding, callback) {
                    this.push(JSON.stringify(chunk, null, 4) + '\n');
                    callback();
                });
// message.value --> value/text to write in write.txt 
jsonStream.write(JSON.parse(message.value));
var writeStream = sftp.createWriteStream("/path/to/write/write.txt");

//"close" event didn't work for me!
writeStream.on( 'close', function () {
    console.log( "- done!" );
    sftp.end();
    }
);

//"finish" event didn't work for me either!
writeStream.on( 'close', function () {
    console.log( "- done!"
        sftp.end();
        }
);

// finally this worked for me!
jsonStream.on('data', function(data) {
    var toString = Object.prototype.toString.call(data);
    console.log('type of data:', toString);
    console.log( "- file transferred" );
});

jsonStream.pipe( writeStream );

If it is MySql you can try

SELECT @n := @n + 1 n,
       first_name, 
       last_name
  FROM table1, (SELECT @n := 0) m
 ORDER BY first_name, last_name

SQLFiddle

And for SQLServer

SELECT row_number() OVER (ORDER BY first_name, last_name) n,
       first_name, 
       last_name 
  FROM table1 

SQLFiddle

You can use ElementRef as shown below,

DEMO : https://plnkr.co/edit/XZwXEh9PZEEVJpe0BlYq?p=preview check browser's console.

import { Directive,Input,Outpu,ElementRef,Renderer} from '@angular/core';

@Directive({
  selector:"[move]",
  host:{
    '(click)':"show()"
  }
})

export class GetEleDirective{

  constructor(private el:ElementRef){

  }
  show(){
    console.log(this.el.nativeElement);

    console.log('height---' + this.el.nativeElement.offsetHeight);  //<<<===here
    console.log('width---' + this.el.nativeElement.offsetWidth);    //<<<===here
  }
}

Same way you can use it within component itself wherever you need it.

If we stop the algorithm in middle prim's algorithm always generates connected tree, but kruskal on the other hand can give disconnected tree or forest

You need to use the NVL function, e.g.

SUM(NVL(regular,0) + NVL(overtime,0))

Since eggyal didn't provided his comment as answer after he gave right advice in a comment - i am posting it here: In my case I had to install module php-mysql. See comments under the question for details.

Edited answer.

After having some experience with both these APIs, I would say that there are 2 blocking level features which renders mysqli unusable with native prepared statements.
They were already mentioned in 2 excellent (yet way underrated) answers:

1. Binding values to arbitrary number of placeholders
2. Returning data as a mere array

(both also mentioned in this answer)

For some reason mysqli failed with both.
Nowadays it got some improvement for the second one (get_result), but it works only on mysqlnd installations, means you can't rely on this function in your scripts.

Yet it doesn't have bind-by-value even to this day.

So, there is only one choice: PDO

All the other reasons, such as

• named placeholders (this syntax sugar is way overrated)
• different databases support (nobody actually ever used it)
• fetch into object (just useless syntax sugar)
• speed difference (there is none)

aren't of any significant importance.

At the same time both these APIs lacks some real important features, like

• identifier placeholder
• placeholder for the complex data types to make dynamical binding less toilsome
• shorter application code.

So, to cover the real life needs, one have to create their own abstraction library, based on one of these APIs, implementing manually parsed placeholders. In this case I'd prefer mysqli, for it has lesser level of abstraction.

They both do the same thing (unless someone's done something unusual), other than that your second one creates an object and adds a property to it. But literal notation takes less space in the source code. It's clearly recognizable as to what is happening, so using new Object(), you are really just typing more and (in theory, if not optimized out by the JavaScript engine) doing an unnecessary function call.

These

person = new Object() /*You should put a semicolon here too.  
It's not required, but it is good practice.*/ 
-or-

person = {
    property1 : "Hello"
};

technically do not do the same thing. The first just creates an object. The second creates one and assigns a property. For the first one to be the same you then need a second step to create and assign the property.

The "something unusual" that someone could do would be to shadow or assign to the default Object global:

// Don't do this
Object = 23;

In that highly-unusual case, new Object will fail but {} will work.

In practice, there's never a reason to use new Object rather than {} (unless you've done that very unusual thing).

Arrays have numerical indexes. So,

a = new Array();
a['a1']='foo';
a['a2']='bar';

and

b = new Array(2);
b['b1']='foo';
b['b2']='bar';

are not adding elements to the array, but adding .a1 and .a2 properties to the a object (arrays are objects too). As further evidence, if you did this:

a = new Array();
a['a1']='foo';
a['a2']='bar';
console.log(a.length);   // outputs zero because there are no items in the array

Your third option:

c=['c1','c2','c3'];

is assigning the variable c an array with three elements. Those three elements can be accessed as: c[0], c[1] and c[2]. In other words, c[0] === 'c1' and c.length === 3.

Javascript does not use its array functionality for what other languages call associative arrays where you can use any type of key in the array. You can implement most of the functionality of an associative array by just using an object in javascript where each item is just a property like this.

a = {};
a['a1']='foo';
a['a2']='bar';

It is generally a mistake to use an array for this purpose as it just confuses people reading your code and leads to false assumptions about how the code works.

It's the array that's causing trouble in:

void print_graph(g_node graph_node[], double weight[][], int nodes);

The second and subsequent dimensions must be given:

void print_graph(g_node graph_node[], double weight[][32], int nodes);

Or you can just give a pointer to pointer:

void print_graph(g_node graph_node[], double **weight, int nodes);

However, although they look similar, those are very different internally.

If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):

void fvla(int m, int C[m][m]); // valid: VLA with prototype scope

void fvla(int m, int C[m][m])  // valid: adjusted to auto pointer to VLA
{
    typedef int VLA[m][m];     // valid: block scope typedef VLA
    struct tag {
        int (*y)[n];           // invalid: y not ordinary identifier
        int z[n];              // invalid: z not ordinary identifier
    };
    int D[m];                  // valid: auto VLA
    static int E[m];           // invalid: static block scope VLA
    extern int F[m];           // invalid: F has linkage and is VLA
    int (*s)[m];               // valid: auto pointer to VLA
    extern int (*r)[m];        // invalid: r has linkage and points to VLA
    static int (*q)[m] = &B;   // valid: q is a static block pointer to VLA
}

Question in comments

[...] In my main(), the variable I am trying to pass into the function is a double array[][], so how would I pass that into the function? Passing array[0][0] into it gives me incompatible argument type, as does &array and &array[0][0].

In your main(), the variable should be:

double array[10][20];

or something faintly similar; maybe

double array[][20] = { { 1.0, 0.0, ... }, ... };

You should be able to pass that with code like this:

typedef struct graph_node
{
    int X;
    int Y;
    int active;
} g_node;

void print_graph(g_node graph_node[], double weight[][20], int nodes);

int main(void)
{
    g_node g[10];
    double array[10][20];
    int n = 10;

    print_graph(g, array, n);
    return 0;
}

That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:

/usr/bin/gcc -O3 -g -std=c99 -Wall -Wextra -c zzz.c

I just had the same problem and ended up doing:

git rebase -i HEAD~N

(N is the number of commits git will show you)

That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.

There are a couple of parallization bugs in SQL server with abnormal input. OPTION(MAXDOP 1) will sidestep them.

EDIT: Old. My testing was done largely on SQL 2005. Most of these seem to not exist anymore, but every once in awhile we question the assumption when SQL 2014 does something dumb and we go back to the old way and it works. We never managed to demonstrate that it wasn't just a bad plan generation on more recent cases though since SQL server can be relied on to get the old way right in newer versions. Since all cases were IO bound queries MAXDOP 1 doesn't hurt.

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

Create the list (edited):

count_list = range(1, N+1)

Select random element:

import random
random.choice(count_list)

for react-router V5 and above use below syntax for multiple paths

<Route
          exact
          path={[path1, path2]}
          component={component}
        />

It works fine by running genymotion with administrative privileges.

I solved it by deleting all of file in Ova,Templates and Deployed folder, I can run download and reinstall again and run without Administrative privileges

You can do it using pageContext attributes, though:

In the JSP:

<form action="Enter.do">
    <button type="SUBMIT" id="btnSubmit" name="btnSubmit">SUBMIT</button>
</form>
<% String s="opportunity";
pageContext.setAttribute("opp", s, PageContext.APPLICATION_SCOPE); %>

In the Servlet (linked to the "Enter.do" url-pattern):

String s=(String) request.getServletContext().getAttribute("opp");

There are other scopes besides APPLICATION_SCOPE like SESSION_SCOPE. APPLICATION_SCOPE is used for ServletContext attributes.

I did it that way in C# with NHibernate, but it should work the same way in Java:

public virtual void Attach()
{
    if (!HibernateSessionManager.Instance.GetSession().Contains(this))
    {
        ISession session = HibernateSessionManager.Instance.GetSession();
        using (ITransaction t = session.BeginTransaction())
        {
            session.Lock(this, NHibernate.LockMode.None);
            t.Commit();
        }
    }
}

First Lock was called on every object because Contains was always false. The problem is that NHibernate compares objects by database id and type. Contains uses the equals method, which compares by reference if it's not overwritten. With that equals method it works without any Exceptions:

public override bool Equals(object obj)
{
    if (this == obj) { 
        return true;
    } 
    if (GetType() != obj.GetType()) {
        return false;
    }
    if (Id != ((BaseObject)obj).Id)
    {
        return false;
    }
    return true;
}

If the table cell is the size that you want, just add this css class and assign it to your div:

.block {
   height: -webkit-calc(100vh);
   height: -moz-calc(100vh);
   height: calc(100vh);
   width: 100%;
}

If you want the table cell to fill up the parent too, assign the class to table cell too. I hope it helps.

Use Select-Object (whose alias is select) with the -Unique switch; e.g.:

$a = @(1,2,3,4,5,5,6,7,8,9,0,0)
$a = $a | select -Unique

If you control the remote server, you should probably use CORS, as described in this answer; it's supported in IE8 and up, and all recent versions of FF, GC, and Safari. (But in IE8 and 9, CORS won't allow you to send cookies in the request.)

So, if you don't control the remote server, or if you have to support IE7, or if you need cookies and you have to support IE8/9, you'll probably want to use an iframe technique.

1. Create an iframe with a unique name. (iframes use a global namespace for the entire browser, so pick a name that no other website will use.)
2. Construct a form with hidden inputs, targeting the iframe.
3. Submit the form.

Here's sample code; I tested it on IE6, IE7, IE8, IE9, FF4, GC11, S5.

function crossDomainPost() {
  // Add the iframe with a unique name
  var iframe = document.createElement("iframe");
  var uniqueString = "CHANGE_THIS_TO_SOME_UNIQUE_STRING";
  document.body.appendChild(iframe);
  iframe.style.display = "none";
  iframe.contentWindow.name = uniqueString;

  // construct a form with hidden inputs, targeting the iframe
  var form = document.createElement("form");
  form.target = uniqueString;
  form.action = "http://INSERT_YOUR_URL_HERE";
  form.method = "POST";

  // repeat for each parameter
  var input = document.createElement("input");
  input.type = "hidden";
  input.name = "INSERT_YOUR_PARAMETER_NAME_HERE";
  input.value = "INSERT_YOUR_PARAMETER_VALUE_HERE";
  form.appendChild(input);

  document.body.appendChild(form);
  form.submit();
}

Beware! You won't be able to directly read the response of the POST, since the iframe exists on a separate domain. Frames aren't allowed to communicate with each other from different domains; this is the same-origin policy.

If you control the remote server but you can't use CORS (e.g. because you're on IE8/IE9 and you need to use cookies), there are ways to work around the same-origin policy, for example by using window.postMessage and/or one of a number of libraries allowing you to send cross-domain cross-frame messages in older browsers:

• Porthole
• XSSInterface
• EasyXDM
• jQuery PostMessage Plugin

If you don't control the remote server, then you can't read the response of the POST, period. It would cause security problems otherwise.

date() itself is only for formatting, but it accepts a second parameter.

date("F j, Y", time() - 60 * 60 * 24);

To keep it simple I just subtract 24 hours from the unix timestamp.

A modern oop-approach is using DateTime

$date = new DateTime();
$date->sub(new DateInterval('P1D'));
echo $date->format('F j, Y') . "\n";

Or in your case (more readable/obvious)

$date = new DateTime();
$date->add(DateInterval::createFromDateString('yesterday'));
echo $date->format('F j, Y') . "\n";

(Because DateInterval is negative here, we must add() it here)

See also: DateTime::sub() and DateInterval

Further to the Mark Parnell's answer, a quick-and-dirty way of getting around this is to put the manifest plist into Dropbox, and then using the Dropbox web interface to get a direct https link to it ('Share link' -> 'Get link' -> 'Download').

The actual ipa can remain wherever you always served it from. You'll need to URL-encode the plist's URL before inserting it into the itms-servivces URL's query (although just replacing any &s with %3D might work).

One downside is that the install dialog will now read "dl.dropbox.com wants to install [whatever]".

https://developer.mozilla.org/en/CSS/Media_queries#-moz-device-pixel-ratio

-moz-device-pixel-ratio
Gives the number of device pixels per CSS pixel.

this is almost self-explaining. the number describes the ratio of how much "real" pixels (physical pixerls of the screen) are used to display one "virtual" pixel (size set in CSS).

If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m

Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini file which is present in your Eclipse home directory.

To get the size of the JVM during Runtime you can use Runtime.totalMemory() which returns the total amount of memory in the Java virtual machine, measured in bytes.

This site has two pretty simple solutions - just check the code, I provided the descriptions in case you wanted them - saves you some clicks.

http://www.richardlord.net/blog/dates-in-php-and-mysql

1.One common solution is to store the dates in DATETIME fields and use PHPs date() and strtotime() functions to convert between PHP timestamps and MySQL DATETIMEs. The methods would be used as follows -

$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
$phpdate = strtotime( $mysqldate );

2.Our second option is to let MySQL do the work. MySQL has functions we can use to convert the data at the point where we access the database. UNIX_TIMESTAMP will convert from DATETIME to PHP timestamp and FROM_UNIXTIME will convert from PHP timestamp to DATETIME. The methods are used within the SQL query. So we insert and update dates using queries like this -

$query = "UPDATE table SET
    datetimefield = FROM_UNIXTIME($phpdate)
    WHERE...";
$query = "SELECT UNIX_TIMESTAMP(datetimefield)
    FROM table WHERE...";

length of string ==how many bits that string having, size==size of those bits, In strings both are same if the editor allocates size of character is 1 byte

Try git diff --ignore-space-at-eol, or git diff --ignore-space-change, or git diff --ignore-all-space.

Here is my java implementation that remove duplicate.

public static int[] mergesort(int[] a, int[] b) {
    int[] c = new int[a.length + b.length];
    int i = 0, j = 0, k = 0, duplicateCount = 0;

    while (i < a.length || j < b.length) {
        if (i < a.length && j < b.length) {
            if (a[i] == b[j]) {
                c[k] = a[i];
                i++;j++;duplicateCount++;
            } else {
                c[k] = a[i] < b[j] ? a[i++] : b[j++];
            }
        } else if (i < a.length) {
            c[k] = a[i++];
        } else if (j < a.length) {
            c[k] = b[j++];
        }
        k++;
    }

    return Arrays.copyOf(c, c.length - duplicateCount);
}

An alternate I would suggest in this use case is to use the MAX(t_stamp) to get the latest row ... e.g.

select t.* from raceway_input_labo t
where t.t_stamp = (select max(t_stamp) from raceway_input_labo) 
limit 1

My coding pattern preference (perhaps) - reliable, generally performs at or better than trying to select the 1st row from a sorted list - also the intent is more explicitly readable.
Hope this helps ...

SQLer

In Socket.IO 1.4

To get the array of All connected Users :

var allConnectedClients = Object.keys(io.sockets.connected);// This will return the array of SockeId of all the connected clients

To get the Count of all clients :

var clientsCount = io.engine.clientsCount ; // This will return the count of connected clients

This kind of error can be caused by LF vs CRLF line ending mismatches, e.g. when you're looking at the patch file and you're absolutely sure it should be able to apply, but it just won't.

To test this out, if you have a patch that applies to just one file, you can try running 'unix2dos' or 'dos2unix' on just that file (try both, to see which one causes the file to change; you can get these utilities for Windows as well as Unix), then commit that change as a test commit, then try applying the patch again. If that works, that was the problem.

NB git am applies patches as LF by default (even if the patch file contains CRLF), so if you want to apply CRLF patches to CRLF files you must use git am --keep-cr, as per this answer.

I use this command to print the status code without any other output. Additionally, it will only perform a HEAD request and follow the redirection (respectively -I and -L).

curl -o -I -L -s -w "%{http_code}" http://localhost

This makes it very easy to check the status code in a health script:

sh -c '[ $(curl -o -I -L -s -w "%{http_code}" http://localhost) -eq 200 ]'

The short answer is that scripting is unsupported in emails.

This is hardly surprising, given the obvious security risks involved with a script running inside an application that has all that personal information stored in it.

Webmail clients are mostly running the interface in JavaScript and are not keen on your email interfering with that, and desktop client filters often consider JavaScript to be an indicator of spam or phishing emails. Even in the cases where it might run, there really is little benefit to scripting in emails.

Keep your emails as straight HTML and CSS, and avoid the hassle. Here is what you can do in html emails: https://www.campaignmonitor.com/guides/coding/technologies/

When you use conda managing your python envs, follow these two steps:

1. activate py3 (on Windows or source activate py3 on Linux)
2. conda install notebook ipykernel or just use conda install jupyter

Maybe your VMnet8 ip is not in the same network segment, e.g., my vm ip is 192.168.71.105, I can ping my windows in vm, but can't ping vm in windows, so this time you may check if vmnet8 is configured right. IP: 192.168.71.1

Can you try this,

 $ch = curl_init($url);
 ...
 curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);

Here are two functions to get the page height and the scroll amounts (x,y) without the use of the (bloated) dimensions plugin:

// getPageScroll() by quirksmode.com
function getPageScroll() {
    var xScroll, yScroll;
    if (self.pageYOffset) {
      yScroll = self.pageYOffset;
      xScroll = self.pageXOffset;
    } else if (document.documentElement && document.documentElement.scrollTop) {
      yScroll = document.documentElement.scrollTop;
      xScroll = document.documentElement.scrollLeft;
    } else if (document.body) {// all other Explorers
      yScroll = document.body.scrollTop;
      xScroll = document.body.scrollLeft;
    }
    return new Array(xScroll,yScroll)
}

// Adapted from getPageSize() by quirksmode.com
function getPageHeight() {
    var windowHeight
    if (self.innerHeight) { // all except Explorer
      windowHeight = self.innerHeight;
    } else if (document.documentElement && document.documentElement.clientHeight) {
      windowHeight = document.documentElement.clientHeight;
    } else if (document.body) { // other Explorers
      windowHeight = document.body.clientHeight;
    }
    return windowHeight
}

Try this , we can append string in php with dot (.) symbol

$data1 = "the color is";
$data2 = "red";

echo $data1.$data2; //the color isred
echo $data1." ".$data2; // the color is red (we have appended space)

As mentioned earlier, the __del__ functionality is somewhat unreliable. In cases where it might seem useful, consider using the __enter__ and __exit__ methods instead. This will give a behaviour similar to the with open() as f: pass syntax used for accessing files. __enter__ is automatically called when entering the scope of with, while __exit__ is automatically called when exiting it. See this question for more details.

I tried many of the above suggestions, including SuperSU and couldn't get any to work but found something much simpler that worked for my purposes. In my case, I only wanted to be able to run sqlite at the command prompt. I simply spun up an emulator with an older version of Android (Lollipop) and got root access immediately.

DBNull.Value is what the .NET Database providers return to represent a null entry in the database. DBNull.Value is not null and comparissons to null for column values retrieved from a database row will not work, you should always compare to DBNull.Value.

What you've done by following those directions is created an entirely new Python installation, separate from the system Python that is managed by Ubuntu packages.

Modules you had installed in the system Python (e.g. installed via packages, or by manual installation using the system Python to run the setup process) will not be available, since your /usr/local-based python is configured to look in its own module directories, not the system Python's.

You can re-add missing modules now by building them and installing them using your new /usr/local-based Python.

I had a need to add a guid primary key column in an existing table and populate it with unique GUID's and this update query with inner select worked for me:

Yes you can do it. Why don't you just try doing that?

I had to use:

-webkit-perspective: 1000;
-webkit-backface-visibility: hidden;

Forget about the react first:
This is not related to react and let us understand the basic concepts of Java Script. For Example you have written following function in java script (name is A).

function a() {

};

Q.1) How to call the function that we have defined?
Ans: a();

Q.2) How to pass reference of function so that we can call it latter?
Ans: let fun = a;

Now coming to your question, you have used paranthesis with function name, mean that function will be called when following statement will be render.

<td><span onClick={this.toggle()}>Details</span></td>

Then How to correct it?
Simple!! Just remove parenthesis. By this way you have given the reference of that function to onClick event. It will call back your function only when your component is clicked.

 <td><span onClick={this.toggle}>Details</span></td>

One suggestion releated to react:
Avoid using inline function as suggested by someone in answers, it may cause performance issue. Avoid following code, It will create instance of same function again and again whenever function will be called (lamda statement creates new instance every time).
Note: and no need to pass event (e) explicitly to the function. you can access it with in the function without passing it.

{<td><span onClick={(e) => this.toggle(e)}>Details</span></td>}

In Python 3.4 or newer you can use pathlib to do recursive globbing:

>>> import pathlib
>>> sorted(pathlib.Path('.').glob('**/*.py'))
[PosixPath('build/lib/pathlib.py'),
 PosixPath('docs/conf.py'),
 PosixPath('pathlib.py'),
 PosixPath('setup.py'),
 PosixPath('test_pathlib.py')]

Reference: https://docs.python.org/3/library/pathlib.html#pathlib.Path.glob

In Python 3.5 or newer you can also do recursive globbing like this:

>>> import glob
>>> glob.glob('**/*.txt', recursive=True)
['2.txt', 'sub/3.txt']

Reference: https://docs.python.org/3/library/glob.html#glob.glob

To just return a list containing the most common words:

from collections import Counter
words=["i", "love", "you", "i", "you", "a", "are", "you", "you", "fine", "green"]
most_common_words= [word for word, word_count in Counter(words).most_common(3)]
print most_common_words

this prints:

['you', 'i', 'a']

the 3 in "most_common(3)", specifies the number of items to print. Counter(words).most_common() returns a a list of tuples with each tuple having the word as the first member and the frequency as the second member.The tuples are ordered by the frequency of the word.

`most_common = [item for item in Counter(words).most_common()]
print(str(most_common))
[('you', 4), ('i', 2), ('a', 1), ('are', 1), ('green', 1), ('love',1), ('fine', 1)]`

"the word for word, word_counter in", extracts only the first member of the tuple.

simply pass your entire code as an argument of timeit:

import timeit

print(timeit.timeit(

"""   
limit = 10000
prime_list = [i for i in range(2, limit+1)]

for prime in prime_list:
    for elem in range(prime*2, max(prime_list)+1, prime):
        if elem in prime_list:
            prime_list.remove(elem)
"""   
, number=10))

you can use <pre> tag :

<div class="text">_x000D_
<pre>_x000D_
abc_x000D_
def_x000D_
ghi_x000D_
</pre>_x000D_
</div>

This might be a very late reply but it is working for us. We are using the same gallery provided by Android, just that, we have adjusted the left margin such a way that the screens left end is considered as Gallery's center. That really worked well for us.

q = request.GET.get("q", None)
if q:
    message = 'q= %s' % q
else:
    message = 'Empty'

I suggest using Postman to generate the request code. Simply make the request using Postman then hit the code tab:

Then you'll get the following window to choose in which language you want your request code to be:

Adding a circle around a number can be easily done with CSS. This can be done using the border-radius property.

Here, we also used the display property set to "inline-block" to represent the element as an inline-level block container.

  span.circle {
  background: #010101;
  border-radius: 50%;
  -moz-border-radius: 50%;
  -webkit-border-radius: 50%;
  color: #f1f1f1;
  display: inline-block;
  font-weight: bold;
  line-height: 40px;
  margin-right: 5px;
  text-align: center;
  width: 40px;
}

 <span class="circle">1</span>

Just add a div around the container so it looks like:

<div style="background: red;">
  <div class="container marketing">
    <h2 style="padding-top: 60px;"></h2>
  </div>
</div>

To add multiples params or headers you can do the following:

constructor(private _http: HttpClient) {}

//....

const url = `${environment.APP_API}/api/request`;

let headers = new HttpHeaders().set('header1', hvalue1); // create header object
headers = headers.append('header2', hvalue2); // add a new header, creating a new object
headers = headers.append('header3', hvalue3); // add another header

let params = new HttpParams().set('param1', value1); // create params object
params = params.append('param2', value2); // add a new param, creating a new object
params = params.append('param3', value3); // add another param 

return this._http.get<any[]>(url, { headers: headers, params: params })

typedef enum state {DEAD,ALIVE} State;
|     | |                     | |   |^ terminating semicolon, required! 
|     | |   type specifier    | |   |
|     | |                     | ^^^^^  declarator (simple name)
|     | |                     |    
|     | ^^^^^^^^^^^^^^^^^^^^^^^  
|     |
^^^^^^^-- storage class specifier (in this case typedef)

The typedef keyword is a pseudo-storage-class specifier. Syntactically, it is used in the same place where a storage class specifier like extern or static is used. It doesn't have anything to do with storage. It means that the declaration doesn't introduce the existence of named objects, but rather, it introduces names which are type aliases.

After the above declaration, the State identifier becomes an alias for the type enum state {DEAD,ALIVE}. The declaration also provides that type itself. However that isn't typedef doing it. Any declaration in which enum state {DEAD,ALIVE} appears as a type specifier introduces that type into the scope:

enum state {DEAD, ALIVE} stateVariable;

If enum state has previously been introduced the typedef has to be written like this:

typedef enum state State;

otherwise the enum is being redefined, which is an error.

Like other declarations (except function parameter declarations), the typedef declaration can have multiple declarators, separated by a comma. Moreover, they can be derived declarators, not only simple names:

typedef unsigned long ulong, *ulongptr;
|     | |           | |  1 | |   2   |
|     | |           | |    | ^^^^^^^^^--- "pointer to" declarator
|     | |           | ^^^^^^------------- simple declarator
|     | ^^^^^^^^^^^^^-------------------- specifier-qualifier list
^^^^^^^---------------------------------- storage class specifier

This typedef introduces two type names ulong and ulongptr, based on the unsigned long type given in the specifier-qualifier list. ulong is just a straight alias for that type. ulongptr is declared as a pointer to unsigned long, thanks to the * syntax, which in this role is a kind of type construction operator which deliberately mimics the unary * for pointer dereferencing used in expressions. In other words ulongptr is an alias for the "pointer to unsigned long" type.

Alias means that ulongptr is not a distinct type from unsigned long *. This is valid code, requiring no diagnostic:

unsigned long *p = 0;
ulongptr q = p;

The variables q and p have exactly the same type.

The aliasing of typedef isn't textual. For instance if user_id_t is a typedef name for the type int, we may not simply do this:

unsigned user_id_t uid;  // error! programmer hoped for "unsigned int uid". 

This is an invalid type specifier list, combining unsigned with a typedef name. The above can be done using the C preprocessor:

#define user_id_t int
unsigned user_id_t uid;

whereby user_id_t is macro-expanded to the token int prior to syntax analysis and translation. While this may seem like an advantage, it is a false one; avoid this in new programs.

Among the disadvantages that it doesn't work well for derived types:

 #define silly_macro int *

 silly_macro not, what, you, think;

This declaration doesn't declare what, you and think as being of type "pointer to int" because the macro-expansion is:

 int * not, what, you, think;

The type specifier is int, and the declarators are *not, what, you and think. So not has the expected pointer type, but the remaining identifiers do not.

And that's probably 99% of everything about typedef and type aliasing in C.

The only way to do that with pure javascript is to implement some kind of polling mechanism. You will need to send ajax requests at fixed intervals (each 5 seconds for example) to get the number of bytes received by the server.

A more efficient way would be to use flash. The flex component FileReference dispatchs periodically a 'progress' event holding the number of bytes already uploaded. If you need to stick with javascript, bridges are available between actionscript and javascript. The good news is that this work has been already done for you :)

swfupload

This library allows to register a javascript handler on the flash progress event.

This solution has the hudge advantage of not requiring aditionnal resources on the server side.

     - return your value inside 
    +capture your value outside

If you want to reset the selected options

$('select option:selected').removeAttr('selected');

If you actually want to remove the options (although I don't think you mean this).

$('select').empty();

Substitute select for the most appropriate selector in your case (this may be by id or by CSS class). Using as is will reset all <select> elements on the page

Check your URL's protocol.

You will also see this error if you host an encrypted page (https) and open it as plain text (http) in Firefox.

I haven't checked this extensively, but I'm under the impression that this isn't (yet?) possible, due to the way in which select elements are generated by the OS on which the browser runs, rather than the browser itself.

I was using the $('div').attr('style', ''); technique and it wasn't working in IE8.

I outputted the style attribute using alert() and it was not stripping out inline styles.

.removeAttr ended up doing the trick in IE8.

MySql have an application to import db from microsoft sql. Steps:

1. Open MySql Workbench
2. Click on "Database Migration" (if it do not appear you have to install it from MySql update)
3. Follow the Migration Task List using the simple Wizard.

Use sha1 to generate checksum:

if (!$variablename) { Write-Host "variable is null" }

I hope this simple answer will is resolve the question. Source

This should work (adapted from https://stackoverflow.com/a/8285722/388902).

var ctrl_down = false;
var ctrl_key = 17;
var s_key = 83;

$(document).keydown(function(e) {
    if (e.keyCode == ctrl_key) ctrl_down = true;
}).keyup(function(e) {
    if (e.keyCode == ctrl_key) ctrl_down = false;
});

$(document).keydown(function(e) {
    if (ctrl_down && (e.keyCode == s_key)) {
        alert('Ctrl-s pressed');
        // Your code
        return false;
    }
}); 

Also you can try this, if you want to focus on same text after error.

If you wants to show this error message in a paragraph then you can use this one:

 $(document).ready(function () {
    $("#submit").click(function () {
        if($('#selBooks').val() === '') {
            $("#Paragraph_id").text("Please select a book and then proceed.").show();
            $('#selBooks').focus();
            return false;
        }
    });
 });

According to the Quartz-Scheduler Tutorial It should be value="0 0/30 * * * ?"

One reason why your scripts could be loading so slowly is if you were running all of your scripts while loading the page, like this:

callMyFunctions();

instead of:

$(window).load(function() {
      callMyFunctions();
});

This second bit of script waits until the browser has completely loaded all of your Javascript code before it starts executing any of your scripts, making it appear to the user that the page has loaded faster.

If you're looking to enhance the user's experience by decreasing the loading time, I wouldn't go for the "loading screen" option. In my opinion that would be much more annoying than just having the page load more slowly.

Practical example:

Imagine that you are modelling something like an I2C bus (signals called SCL for clock and SDA for data), where the bus is tri-state and both nets have a weak pull-up. Your testbench should model the pull-up resistor on the PCB with a value of 'H'.

scl <= 'H'; -- Testbench resistor pullup

Your I2C master or slave devices can drive the bus to '1' or '0' or leave it alone by assigning a 'Z'

Assigning a '1' to the SCL net will cause an event to happen, because the value of SCL changed.

• If you have a line of code that relies on (scl'event and scl = '1'), then you'll get a false trigger.

• If you have a line of code that relies on rising_edge(scl), then you won't get a false trigger.

Continuing the example: you assign a '0' to SCL, then assign a 'Z'. The SCL net goes to '0', then back to 'H'.

Here, going from '1' to '0' isn't triggering either case, but going from '0' to 'H' will trigger a rising_edge(scl) condition (correct), but the (scl'event and scl = '1') case will miss it (incorrect).

General Recommenation:

Use rising_edge(clk) and falling_edge(clk) instead of clk'event for all code.

Try the following: string.replace(/[^0-9]/g, ''); This will delete all non-digit characters, leaving only digits in the string

function retnum(str) { 
    var num = str.replace(/[^0-9]/g, ''); 
    return parseInt(num,10); 
}

console.log('abca12bc45qw'.replace(/[^0-9]/g, ''));_x000D_
console.log('#box2'.replace(/[^0-9]/g, ''));

I assume you used splice something like this?

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) !== -1) {
        arrayOfObjects.splice(i, 1);
    }
}

All you need to do to fix the bug is decrement i for the next time around, then (and looping backwards is also an option):

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) !== -1) {
        arrayOfObjects.splice(i, 1);
        i--;
    }
}

To avoid linear-time deletions, you can write array elements you want to keep over the array:

var end = 0;

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) === -1) {
        arrayOfObjects[end++] = obj;
    }
}

arrayOfObjects.length = end;

and to avoid linear-time lookups in a modern runtime, you can use a hash set:

const setToDelete = new Set(listToDelete);
let end = 0;

for (let i = 0; i < arrayOfObjects.length; i++) {
    const obj = arrayOfObjects[i];

    if (setToDelete.has(obj.id)) {
        arrayOfObjects[end++] = obj;
    }
}

arrayOfObjects.length = end;

which can be wrapped up in a nice function:

const filterInPlace = (array, predicate) => {_x000D_
    let end = 0;_x000D_
_x000D_
    for (let i = 0; i < array.length; i++) {_x000D_
        const obj = array[i];_x000D_
_x000D_
        if (predicate(obj)) {_x000D_
            array[end++] = obj;_x000D_
        }_x000D_
    }_x000D_
_x000D_
    array.length = end;_x000D_
};_x000D_
_x000D_
const toDelete = new Set(['abc', 'efg']);_x000D_
_x000D_
const arrayOfObjects = [{id: 'abc', name: 'oh'},_x000D_
                        {id: 'efg', name: 'em'},_x000D_
                        {id: 'hij', name: 'ge'}];_x000D_
_x000D_
filterInPlace(arrayOfObjects, obj => !toDelete.has(obj.id));_x000D_
console.log(arrayOfObjects);

If you don’t need to do it in place, that’s Array#filter:

const toDelete = new Set(['abc', 'efg']);
const newArray = arrayOfObjects.filter(obj => !toDelete.has(obj.id));

A save method to determine the width and height unit of any element (no padding, no margin) is the following:

let div   = document.querySelector("div");
let style = getComputedStyle(div);

let width  = parseFloat(style.width.replace("px", ""));
let height = parseFloat(style.height.replace("px", ""));

in my case, it was fixed when I removed the virtual keyword before my navigation properties, I mean the reference tables. so I changed

public virtual MembershipType MembershipType { get; set; }

to:

public MembershipType MembershipType { get; set; }

I made the following module called unicoder to be able to do the transformation on variables:

import sys
import os

def ustr(string):

    string = 'u"%s"'%string

    with open('_unicoder.py', 'w') as script:

        script.write('# -*- coding: utf-8 -*-\n')
        script.write('_ustr = %s'%string)

    import _unicoder
    value = _unicoder._ustr

    del _unicoder
    del sys.modules['_unicoder']

    os.system('del _unicoder.py')
    os.system('del _unicoder.pyc')

    return value

Then in your program you could do the following:

# -*- coding: utf-8 -*-

from unicoder import ustr

txt = 'Hello, Unicode World'
txt = ustr(txt)

print type(txt) # <type 'unicode'>

foreach(Foos foo in Enum.GetValues(typeof(Foos)))

In OSX El Capitan update when you do this:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

it throws an error like

ln: /usr/lib/libmysqlclient.18.dylib: Operation not permitted

So to avoid this, what you can do is first locate libmysqlclient.18.dylib using the command

User$ locate libmysqlclient.18.dylib

In my case it returned /usr/local/mysql-5.5.24-osx10.5-x86_64/lib/libmysqlclient.18.dylib

So instead of usr/lib/ we will create symlink to usr/local/lib/ like this :

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

When I just run this as a page

<?php

echo 'alert("message successfully sent")';
echo '</script>';
exit;

it works fine.

What version of PHP are you running?

Could you try echoing something else after: $testObject->split_for_sms($Chat);

Maybe it doesn't get to that part of the code? You could also try these with the other function calls to check where your program stops/is getting to.

Hope you get a bit further with this.

I would use a UIAlertView with a UITextField subview. You can either add the text field manually or, in iOS 5, use one of the new methods.

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

This does not answer the question directly, but I have on different occasions landed on this Stack Overflow question in order to solve something I would use $watch for in angularJs. I ended up using another approach than described in the current answers, and want to share it in case someone finds it useful.

The technique I use to achieve something similar $watch is to use a BehaviorSubject (more on the topic here) in an Angular service, and let my components subscribe to it in order to get (watch) the changes. This is similar to a $watch in angularJs, but require some more setup and understanding.

In my component:

export class HelloComponent {
  name: string;
  // inject our service, which holds the object we want to watch.
  constructor(private helloService: HelloService){
    // Here I am "watching" for changes by subscribing
    this.helloService.getGreeting().subscribe( greeting => {
      this.name = greeting.value;
    });
  }
}

In my service

export class HelloService {
  private helloSubject = new BehaviorSubject<{value: string}>({value: 'hello'});
  constructor(){}
  // similar to using $watch, in order to get updates of our object 
  getGreeting(): Observable<{value:string}> {
    return this.helloSubject;
  }
  // Each time this method is called, each subscriber will receive the updated greeting.
  setGreeting(greeting: string) {
    this.helloSubject.next({value: greeting});
  }
}

Here is a demo on Stackblitz

I'm pretty mixed up on this. I am also running Excel 2010. I tried saving two sheets as a single PDF using:

    ThisWorkbook.Sheets(Array(1,2)).Select
    **Selection**.ExportAsFixedFormat xlTypePDF, FileName & ".pdf", , , False

but I got nothing but blank pages. It saved both sheets, but nothing on them. It wasn't until I used:

    ThisWorkbook.Sheets(Array(1,2)).Select
    **ActiveSheet**.ExportAsFixedFormat xlTypePDF, FileName & ".pdf", , , False

that I got a single PDF file with both sheets.

I tried manually saving these two pages using Selection in the Options dialog to save the two sheets I had selected, but got blank pages. When I tried the Active Sheet(s) option, I got what I wanted. When I recorded this as a macro, Excel used ActiveSheet when it successfully published the PDF. What gives?

Just execute: ? npm rebuild node-sass --force

1. Delete node-sass folder under node_modules
2. npm install

In my case it also couldn't find Python.

Following procedure solved the issue (Windows):

npm rebuild node-sass --force
-- cannot find python.exe, if you have Python installed, add it to your path:
set PYTHON=C:\Python27\Python.exe
-- else: download python "Windows x86-64-MSI" installer from https://www.python.org/downloads/release/python-2714/
-- install python
-- at installation start check: add env variable to path
-- after successfull installation:
npm rebuild node-sass --force
-- finished successfully

Try using cmake itself. In the build directory, run:

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

This code will print an asterisk instead of every letter.

    if x == '\r':

    passwor +=x

print '\n'+passwor

The approach with istringstream can be improved in order to check that no other characters have been inserted after the expected argument:

#include <sstream>

int main(int argc, char *argv[])
{
    if (argc >= 2)
    {
        std::istringstream iss( argv[1] );
        int val;

        if ((iss >> val) && iss.eof()) // Check eofbit
        {
            // Conversion successful
        }
    }

    return 0;
}

Normally, the error will occur due to an unsuitable AVD emulator for the type of app you are developing for. For example if you are developing an app for a wearable but you are trying to use a phone emulator to run it.

You can use set -e as a prefix for the for-loop. Example:

    set -e; for a in 1 2 3; do /bin/false; echo $$a; done

make will exit immediately with an exit code <> 0.

Personally,

I find many of these terminal text editors incapable at times. Would I invest time picking one up? Absolutely! I would continue to learning one along side a IDE. Of course in the end, it really comes down to preference.

A break will allow you continue processing in the function. Just returning out of the switch is fine if that's all you want to do in the function.

The parameter(s) to isset() must be a variable reference and not an expression (in your case a concatenation); but you can group multiple conditions together like this:

if (isset($_POST['search_term'], $_POST['postcode'])) {
}

This will return true only if all arguments to isset() are set and do not contain null.

Note that isset($var) and isset($var) == true have the same effect, so the latter is somewhat redundant.

Update

The second part of your expression uses empty() like this:

empty ($_POST['search_term'] . $_POST['postcode']) == false

This is wrong for the same reasons as above. In fact, you don't need empty() here, because by that time you would have already checked whether the variables are set, so you can shortcut the complete expression like so:

isset($_POST['search_term'], $_POST['postcode']) && 
    $_POST['search_term'] && 
    $_POST['postcode']

Or using an equivalent expression:

!empty($_POST['search_term']) && !empty($_POST['postcode'])

Final thoughts

You should consider using filter functions to manage the inputs:

$data = filter_input_array(INPUT_POST, array(
    'search_term' => array(
        'filter' => FILTER_UNSAFE_RAW,
        'flags' => FILTER_NULL_ON_FAILURE,
    ),
    'postcode' => array(
        'filter' => FILTER_UNSAFE_RAW,
        'flags' => FILTER_NULL_ON_FAILURE,
    ),
));

if ($data === null || in_array(null, $data, true)) {
    // some fields are missing or their values didn't pass the filter
    die("You did something naughty");
}

// $data['search_term'] and $data['postcode'] contains the fields you want

Btw, you can customize your filters to check for various parts of the submitted values.

Just use this for the closing tag:

  @:</tr>

And leave your if/else as is.

Seems like the if statement doesn't wanna' work.

It works fine. You're working in 2 language-spaces here, it seems only proper not to split open/close sandwiches over the border.

Apart from the <h:panelGroup> component (which comes as a bit of a surprise to me), you could use a <f:verbatim> tag with the escape parameter set to false to generate any mark-up you want. For example:

<f:verbatim escape="true">
    <div id="blah"></div>
</f:verbatim>

Bear in mind it's a little less elegant than the panelGroup solution, as you have to generate this for both the start and end tags if you want to wrap any of your JSF code with the div tag.

Alternatively, all the major UI Frameworks have a div component tag, or you could write your own.

Try setting:

android:indeterminateDrawable="@drawable/progress" 

It worked for me. Here is also the code for progress.xml:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
    android:toDegrees="360">

    <shape android:shape="ring" android:innerRadiusRatio="3"
        android:thicknessRatio="8" android:useLevel="false">

        <size android:width="48dip" android:height="48dip" />

        <gradient android:type="sweep" android:useLevel="false"
            android:startColor="#4c737373" android:centerColor="#4c737373"
            android:centerY="0.50" android:endColor="#ffffd300" />

    </shape>

</rotate> 

Little bit simplified version for the most popular answer in this thread https://stackoverflow.com/a/3067896/5437379 :

function toYYYYMMDD(d) {
    var yyyy = d.getFullYear().toString();
    var mm = (d.getMonth() + 101).toString().slice(-2);
    var dd = (d.getDate() + 100).toString().slice(-2);
    return yyyy + mm + dd;
}

For those of us who this above valid solution didnt work, there's another workaround here

 searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean isFocused) {
            if(!isFocused)
            {
                Toast.makeText(MainActivity.this,"not focused",Toast.LENGTH_SHORT).show();

            }
        }
    });

Yes, your secret key appears to be missing. Without it, you will not be able to decrypt the files.

Do you have the key backed up somewhere?

Re-creating the keys, whether you use the same passphrase or not, will not work. Each key pair is unique.

Replace double quotes with single ones:

INSERT
INTO    MY.LOGFILE
        (id,severity,category,logdate,appendername,message,extrainfo)
VALUES  (
       'dee205e29ec34',
       'FATAL',
       'facade.uploader.model',
       '2013-06-11 17:16:31',
       'LOGDB',
       NULL,
       NULL
       )

In SQL, double quotes are used to mark identifiers, not string constants.

Officially it's Ctrl+F11 & Ctrl+F12 or KEYPAD 7 & KEYPAD 9.

In practise it's a bit quirky.

1. Specifically it's Left Ctrl+F11 and Left Ctrl+F12 to switch to previous orientation and next orientation respectively.

2. You have to release Ctrl before you can rotate again.

3. KEYPAD 7 and KEYPAD 9 only work with Num Lock OFF (so they're acting as Home & PageUp rather than 7 & 9).

4. The only orientations are vertically upright and rotated one quarter-turn anti-clockwise.

Maybe a bit too much info for such a simple question, but it drove me half-mad finding this out.

Note: This was tested on Android SDK R16 and a very old keyboard, modern keyboards may behave differently.

    private boolean isPagingEnabled = true;

    public CustomViewPager(Context context) {
        super(context);
    }

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onInterceptTouchEvent(event);
    }

    public void setPagingEnabled(boolean b) {
        this.isPagingEnabled = b;
    }
}

Then in your Layout.XML file replace any <com.android.support.V4.ViewPager> tags with <com.yourpackage.CustomViewPager> tags.

I had similar issue but I could not resolve it using static ip address or changing firewall settings. I found a useful utility which can be configured in a minute.

We can host our local web server on cloud for free. On exposing it on cloud we get a different URL which we can use instead of localhost and access the webserver from anywhere.

The utility is ngrok https://ngrok.com/download Steps:

1. Signup
2. Download
3. Extract the file and double click to run it, this will open a command prompt
4. Type "ngrok.exe http 80" without quotes to host for example XAMPP apache server which runs on port 80.
5. Copy the new url name generated on the cmd prompt for e.g. if it is like this "fafb42f.ngrok.io"

URL like : http://localhost/php/test.php Should be modified like this : http://fafb42f.ngrok.io/php/test.php

Now this URL can be accessed from phone.

Queue is an interface; you can't explicitly construct a Queue. You'll have to instantiate one of its implementing classes. Something like:

Queue linkedList = new LinkedList();

Here's a link to the Java tutorial on this subject.

I had the same problem but with an other cause. The solution was to deactivate Avira Browser Protection (in german Browser-Schutz). I took the solusion from m2e cannot transfer metadata from nexus, but maven command line can. It can be activated again ones maven has the needed plugin.

There is an optional overload for DataBinder.Eval to supply formatting:

<%# DataBinder.Eval(Container.DataItem, "expression"[, "format"]) %>

The format parameter is a String value, using the value placeholder replacement syntax (called composite formatting) like this:

<asp:Label id="lblNewsDate" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "publishedDate", "{0:dddd d MMMM}") %>'</label>

if you need to run the delete/insert/update you could also run dynamic statements. i.e.:

declare 
    @v_dynDelete                 NVARCHAR(500);

 SET @v_dynDelete = 'DELETE some_table;'; 
 EXEC @v_dynDelete

Single LinearLayout solution. Only adding a simple spacing view:
(No-one seemed to have mentioned this one, only more complicated multi-layout solutions.)

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_marginTop="35dp">

    <TextView
        android:id="@+id/lblExpenseCancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/cancel"
        android:textColor="#404040"
        android:layout_marginLeft="10dp"
        android:textSize="20sp"
        android:layout_marginTop="9dp" />

    <!-------------------------  ADDED SPACER VIEW -------------------->
    <View
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_weight="1"
        />
    <!------------------------- /ADDED SPACER VIEW -------------------->

    <Button
        android:id="@+id/btnAddExpense"
        android:layout_width="wrap_content"
        android:layout_height="45dp"
        android:background="@drawable/stitch_button"
        android:layout_marginLeft="10dp"
        android:text="@string/add"
        android:layout_gravity="right"
        android:layout_marginRight="15dp" />

</LinearLayout>

Note the "highlighted" View, I didn't modify anything else. Height=0 makes sure it's not visible. Width=0 is because the width is determined by the LinearLayout based on weight=1. This means that the spacer view will stretch as much as possible in the direction (orientation) of the LinearLayout.

Note that you should use android.widget.Space or android.support.v4.widget.Space instead of View if your API level and/or dependencies allow it. Space achieves the job in a cheaper way, because it only measures and doesn't try to draw anything like View does; it's also more expressive conveying the intention.

Python 3 includes an improved super() which allows use like this:

super().__init__(args)

As other have answered, the result is exactly the same, None is returned in all cases.

The difference is stylistic, but please note that PEP8 requires the use to be consistent:

Be consistent in return statements. Either all return statements in a function should return an expression, or none of them should. If any return statement returns an expression, any return statements where no value is returned should explicitly state this as return None, and an explicit return statement should be present at the end of the function (if reachable).

Yes:

def foo(x):
    if x >= 0:
        return math.sqrt(x)
    else:
        return None

def bar(x):
    if x < 0:
        return None
    return math.sqrt(x)

No:

def foo(x):
    if x >= 0:
        return math.sqrt(x)

def bar(x):
    if x < 0:
        return
    return math.sqrt(x)

https://www.python.org/dev/peps/pep-0008/#programming-recommendations

Basically, if you ever return non-None value in a function, it means the return value has meaning and is meant to be caught by callers. So when you return None, it must also be explicit, to convey None in this case has meaning, it is one of the possible return values.

If you don't need return at all, you function basically works as a procedure instead of a function, so just don't include the return statement.

If you are writing a procedure-like function and there is an opportunity to return earlier (i.e. you are already done at that point and don't need to execute the remaining of the function) you may use empty an returns to signal for the reader it is just an early finish of execution and the None value returned implicitly doesn't have any meaning and is not meant to be caught (the procedure-like function always returns None anyway).

Your Application.java class should extend the SpringBootServletInitializer class ex:

public class Application extends SpringBootServletInitializer {}

The API return value in my case as shown here:

{
  "pageIndex": 1,
  "pageSize": 10,
  "totalCount": 1,
  "totalPageCount": 1,
  "items": [
    {
      "firstName": "Stephen",
      "otherNames": "Ebichondo",
      "phoneNumber": "+254721250736",
      "gender": 0,
      "clientStatus": 0,
      "dateOfBirth": "1979-08-16T00:00:00",
      "nationalID": "21734397",
      "emailAddress": "[email protected]",
      "id": 1,
      "addedDate": "2018-02-02T00:00:00",
      "modifiedDate": "2018-02-02T00:00:00"
    }
  ],
  "hasPreviousPage": false,
  "hasNextPage": false
}

The conversion of the items array to list of clients was handled as shown here:

 if (responseMessage.IsSuccessStatusCode)
        {
            var responseData = responseMessage.Content.ReadAsStringAsync().Result;
            JObject result = JObject.Parse(responseData);

            var clientarray = result["items"].Value<JArray>();
            List<Client> clients = clientarray.ToObject<List<Client>>();
            return View(clients);
        }

I work on a Windows machine. And here are some pointers for successful installation of lxml (with python 2.6 and later).

Have the following installed:

1. MingGW.
2. libxml2 version 2.7.0 or later.
3. libxslt version 1.1.23 or later.

All are not available at a pip install.

libxml2's windows binary is found here.

libxslt is found here.

After you are done with the above two,

do : pip install lxml.

Another workaround is using the stable releases from PyPI or the unofficial Windows binaries by Christoph Gohlke (found here).

Set in RecyclerView initialization

recyclerView.setLayoutManager(new GridLayoutManager(this, 4));

I think this is very nice and short

<img src="imagenotfound.gif" alt="Image not found" onerror="this.src='imagefound.gif';" />

But, be careful. The user's browser will be stuck in an endless loop if the onerror image itself generates an error.

EDIT To avoid endless loop, remove the onerror from it at once.

<img src="imagenotfound.gif" alt="Image not found" onerror="this.onerror=null;this.src='imagefound.gif';" />

By calling this.onerror=null it will remove the onerror then try to get the alternate image.

NEW I would like to add a jQuery way, if this can help anyone.

<script>
$(document).ready(function()
{
    $(".backup_picture").on("error", function(){
        $(this).attr('src', './images/nopicture.png');
    });
});
</script>

<img class='backup_picture' src='./images/nonexistent_image_file.png' />

You simply need to add class='backup_picture' to any img tag that you want a backup picture to load if it tries to show a bad image.

I tried with many solutions but it didn't work for me so I tried flex with the table and it worked fine for me with all table functionalities like border-collapse and so on only change is display property

This was my HTML requirement

<table>
  <thead>
    <tr>
      <th>1</th>
      <th colspan="3">2</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td colspan="3">2</td>
    </tr>
    <tr>
      <td>1</td>
      <td>2</td>
      <td>3</td>
      <td>4</td>
    </tr>
    <tr>
      <td>1</td>
      <td>2</td>
      <td colspan="2">3</td>
    </tr>
  </tbody>
</table>

My CSS

table{
    display: flex;
  flex-direction: column;
}
table tr{
    display: flex;
  width: 100%;
}
table > thead > tr > th:first-child{
    width: 20%;
}
table > thead > tr > th:last-child{
    width: 80%;
}
table > tbody tr > td:first-child{
    width: 10%;
}
table > tbody tr > td{
    width: 30%;
}
table > tbody tr > td[colspan="2"]{
    width: 60%;
}
table > tbody tr > td[colspan="3"]{
    width: 90%;
}
/*This is to remove border making 1px space on right*/
table > tbody tr > td:last-child{
    border-right: 0;
}

The most robust mechanism for listing all subclasses of a given class is currently ClassGraph, because it handles the widest possible array of classpath specification mechanisms, including the new JPMS module system. (I am the author.)

List<Class<Animal>> animals;
try (ScanResult scanResult = new ClassGraph().whitelistPackages("com.zoo.animals")
        .enableClassInfo().scan()) {
    animals = scanResult
        .getSubclasses(Animal.class.getName())
        .loadClasses(Animal.class);
}

I think I get what you mean. Let's say for example you want the right-most \ in the following string (which is stored in cell A1):

Drive:\Folder\SubFolder\Filename.ext

To get the position of the last \, you would use this formula:

=FIND("@",SUBSTITUTE(A1,"\","@",(LEN(A1)-LEN(SUBSTITUTE(A1,"\","")))/LEN("\")))

That tells us the right-most \ is at character 24. It does this by looking for "@" and substituting the very last "\" with an "@". It determines the last one by using

(len(string)-len(substitute(string, substring, "")))\len(substring)

In this scenario, the substring is simply "\" which has a length of 1, so you could leave off the division at the end and just use:

=FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))

Now we can use that to get the folder path:

=LEFT(A1,FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\","")))))

Here's the folder path without the trailing \

=LEFT(A1,FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))-1)

And to get just the filename:

=MID(A1,FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))+1,LEN(A1))

However, here is an alternate version of getting everything to the right of the last instance of a specific character. So using our same example, this would also return the file name:

=TRIM(RIGHT(SUBSTITUTE(A1,"\",REPT(" ",LEN(A1))),LEN(A1)))

I may guess, the old instance of your program is still running. Windows does not allow to change the files which are currently "in use" and your linker cannot write the new .exe on the top of the running one. Try stopping/killing your program.

Although TripleDESCryptoServiceProvider is a safe and good method but it's too slow. If you want to refer to MSDN you will get that advise you to use AES rather TripleDES. Please check below link: http://msdn.microsoft.com/en-us/library/system.security.cryptography.tripledescryptoserviceprovider.aspx you will see this attention in the remark section:

Note A newer symmetric encryption algorithm, Advanced Encryption Standard (AES), is available. Consider using the AesCryptoServiceProvider class instead of the TripleDESCryptoServiceProvider class. Use TripleDESCryptoServiceProvider only for compatibility with legacy applications and data.

Good luck

After some trial and error, I found that

$computername = $env:computername

works to get a computer name, but sending $computername to a file via Add-Content doesn't work.

I also tried $computername.Value.

Instead, if I use

$computername = get-content env:computername

I can send it to a text file using

$computername | Out-File $file

To do it in a Java file:

EditText input = new EditText(this);
input.setInputType(InputType.TYPE_CLASS_NUMBER);

Here is example given which so how to use open and "python close

from sys import argv
script,filename=argv
txt=open(filename)
print "filename %r" %(filename)
print txt.read()
txt.close()
print "Change the file name"
file_again=raw_input('>')
print "New file name %r" %(file_again)
txt_again=open(file_again)
print txt_again.read()
txt_again.close()

It's necessary to how many times you opened file have to close that times.

If the checkbox is checked, then the checkbox's value will be passed. Otherwise, the field is not passed in the HTTP post.

if (isset($_POST['mycheckbox'])) {
    echo "checked!";
}

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

I had this problem when i was trying to query by passing a Set and i didn't used In

example

problem : repository.findBySomeSetOfData(setOfData);

solution : repository.findBySomeSetOfDataIn(setOfData);

When debugging optimized programs (which may be necessary if the bug doesn't show up in debug builds), you often have to understand assembly compiler generated.

In your particular case, return value of cpnd_find_exact_ckptinfo will be stored in the register which is used on your platform for return values. On ix86, that would be %eax. On x86_64: %rax, etc. You may need to google for '[your processor] procedure calling convention' if it's none of the above.

You can examine that register in GDB and you can set it. E.g. on ix86:

(gdb) p $eax
(gdb) set $eax = 0 

What's wrong with

func (e *Easy)SetStringOption(option Option, param string)
func (e *Easy)SetLongOption(option Option, param long)

and so on?

If you want add Custom method you can do it

(in this case, at least one checkbox selected)

<input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy"  value="1" onclick="test($(this))"/>

in Javascript

var tags = 0;

$(document).ready(function() {   

    $.validator.addMethod('arrayminimo', function(value) {
        return tags > 0
    }, 'Selezionare almeno un Opzione');

    $.validator.addClassRules('check_secondario', {
        arrayminimo: true,

    });

    validaFormRichiesta();
});

function validaFormRichiesta() {
    $("#form").validate({
        ......
    });
}

function test(n) {
    if (n.prop("checked")) {
        tags++;
    } else {
        tags--;
    }
}

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

assuming the item numbers are unique, a VLOOKUP should get you the information you need.

first value would be =VLOOKUP(E1,A:B,2,FALSE), and the same type of formula to retrieve the second value would be =VLOOKUP(E1,C:D,2,FALSE). Wrap them in an IFERROR if you want to return anything other than #N/A if there is no corresponding value in the item column(s)

Try this small lib, works with Angular 5.0.0

• https://www.npmjs.com/package/ng2-file-upload

Quickstart example with ng2-file-upload 1.3.0:

User clicks custom button, which triggers upload dialog from hidden input type="file" , uploading started automatically after selecting single file.

app.module.ts:

import {FileUploadModule} from "ng2-file-upload";

your.component.html:

...
  <button mat-button onclick="document.getElementById('myFileInputField').click()" >
    Select and upload file
  </button>
  <input type="file" id="myFileInputField" ng2FileSelect [uploader]="uploader" style="display:none">
...

your.component.ts:

import {FileUploader} from 'ng2-file-upload';
...    
uploader: FileUploader;
...
constructor() {
   this.uploader = new FileUploader({url: "/your-api/some-endpoint"});
   this.uploader.onErrorItem = item => {
       console.error("Failed to upload");
       this.clearUploadField();
   };
   this.uploader.onCompleteItem = (item, response) => {
       console.info("Successfully uploaded");
       this.clearUploadField();

       // (Optional) Parsing of response
       let responseObject = JSON.parse(response) as MyCustomClass;

   };

   // Asks uploader to start upload file automatically after selecting file
  this.uploader.onAfterAddingFile = fileItem => this.uploader.uploadAll();
}

private clearUploadField(): void {
    (<HTMLInputElement>window.document.getElementById('myFileInputField'))
    .value = "";
}

Alternative lib, works in Angular 4.2.4, but requires some workarounds to adopt to Angular 5.0.0

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

There are a few base64 encoders online to help you with this, this is probably the best I've seen:

http://www.greywyvern.com/code/php/binary2base64

As that page shows your main options for this are CSS:

div.image {
  width:100px;
  height:100px;
  background-image:url(data:image/png;base64,iVBORwA<MoreBase64SringHere>); 
}

Or the <img> tag itself, like this:

<img alt="My Image" src="data:image/png;base64,iVBORwA<MoreBase64SringHere>" />

This problem is caused because of the naming of files in "res" or "drawable" folder. You can't use any capital letter for naming a resource file. So, check if there is any such file and rename it with small letters.

And, also, you can try this: Go to: File > Invalidate cache/restart

These options have worked for me.

Here i show you a snippet where your problem is solved (i know, it's been too long since you posted it, but i think this is cleaner than de "clear" fix)

In Code behind you can achieve it only by doing this.

 private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            txtIndex.Focusable = true;
            txtIndex.Focus();
        }

Note: It wont work before window is loaded

Google is using this to detect whether the device is online or in captive portal.

Shill, the connection manager for Chromium OS, attempts to detect services that are within a captive portal whenever a service transitions to the ready state. This determination of being in a captive portal or being online is done by attempting to retrieve the webpage http://clients3.google.com/generate_204. This well known URL is known to return an empty page with an HTTP status 204. If for any reason the web page is not returned, or an HTTP response other than 204 is received, then shill marks the service as being in the portal state.

Here is the relevant explanation from the Google Chrome Privacy Whitepaper:

In the event that Chrome detects SSL connection timeouts, certificate errors, or other network issues that might be caused by a captive portal (a hotel's WiFi network, for instance), Chrome will make a cookieless request to http://www.gstatic.com/generate_204 and check the response code. If that request is redirected, Chrome will open the redirect target in a new tab on the assumption that it's a login page. Requests to the captive portal detection page are not logged.

The magic method __getitem__ is basically used for accessing list items, dictionary entries, array elements etc. It is very useful for a quick lookup of instance attributes.

Here I am showing this with an example class Person that can be instantiated by 'name', 'age', and 'dob' (date of birth). The __getitem__ method is written in a way that one can access the indexed instance attributes, such as first or last name, day, month or year of the dob, etc.

import copy

# Constants that can be used to index date of birth's Date-Month-Year
D = 0; M = 1; Y = -1

class Person(object):
    def __init__(self, name, age, dob):
        self.name = name
        self.age = age
        self.dob = dob

    def __getitem__(self, indx):
        print ("Calling __getitem__")
        p = copy.copy(self)

        p.name = p.name.split(" ")[indx]
        p.dob = p.dob[indx] # or, p.dob = p.dob.__getitem__(indx)
        return p

Suppose one user input is as follows:

p = Person(name = 'Jonab Gutu', age = 20, dob=(1, 1, 1999))

With the help of __getitem__ method, the user can access the indexed attributes. e.g.,

print p[0].name # print first (or last) name
print p[Y].dob  # print (Date or Month or ) Year of the 'date of birth'

Recently I had to do something similar and I resolved it with the code below. Hope it helps!

Sub ColorCode()
Dim i As Integer
Dim j As Integer
i = 2
j = 1

Do While ActiveSheet.Cells(i, 1) <> ""


If Cells(i, 5).Value = "RED" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(255, 0, 0)



Else

If Cells(i, 5).Value = "GREEN" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(0, 255, 0)

Else

If Cells(i, 5).Value = "GREY" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(192, 192, 192)

Else

If Cells(i, 5).Value = "YELLOW" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(255, 255, 0)

End If
End If
End If
End If

i = i + 1
j = j + 1

Loop



End Sub

Scanner scan = new Scanner(System.in);
String myLine = scan.nextLine();

It is A very simple process: assume you have two tabs so you need to first close the current tab by using client.window(callback) because the switch command "switches to the first available one". Then you can easily switch tab using client.switchTab.

str.replace(/^.+?\"|^.|\".+/, '');

This is sometimes bad to use when you wanna select what else to remove between "" and you cannot use it more than twice in one string. All it does is select whatever is not in between "" and replace it with nothing.

Even for me it is a bit confusing, but ill try to explain it. ^.+? (not anything OPTIONAL) till first " then | Or/stop (still researching what it really means) till/at ^. has selected nothing until before the 2nd " using (| stop/at). And select all that comes after with .+.

The first one, or if (status) { /*second clause*/ } else { /* first clause */ }

EDIT

If the second form is really desired, then if (false == status) <etc>, while uglier, is probably safer (wrt typos).

    public MainWindow()
    {
        // This button needs to exist on your form.
        myButton.Click += myButton_Click;
    }

    void myButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox.Show("Message here");
        this.Close();
    }

1. $ git rm ./*.DS_Store - remove all .DS_Store from git
2. $ echo \.DS_Store >> .gitignore - ignore .DS_Store in future
