I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

I think that depth first search solves it. If an unexplored edge leads to a node visited before, then the graph contains a cycle. This condition also makes it O(n), since you can explore maximum n edges without setting it to true or being left with no unexplored edges.

My workaround:

function add(a, b, precision) {
    var x = Math.pow(10, precision || 2);
    return (Math.round(a * x) + Math.round(b * x)) / x;
}

precision refers to the number of digits you want to preserve after the decimal point during addition.

Use of pointer before character array

Normally, Character array is used to store single elements in it i.e 1 byte each

eg:

char a[]={'a','b','c'};

we can't store multiple value in it.

by using pointer before the character array we can store the multi dimensional array elements in the array

i.e.

char *a[]={"one","two","three"};
printf("%s\n%s\n%s",a[0],a[1],a[2]);

I was able to fix this issue by changing $(document).ready() to window.onLoad().

It's been a long time since I asked this question, but here's an answer that doesn't require jquery:

function change() {
    var scope = angular.element(document.querySelector('#outside')).scope();
    scope.$apply(function(){
        scope.msg = 'Superhero';
    })
}

If you just want to see what's in the database without installing anything extra, you might already have SQLite CLI on your system. To check, open a command prompt and try:

sqlite3 database.sqlite

Replace database.sqlite with your database file. Then, if the database is small enough, you can view the entire contents with:

sqlite> .dump

Or you can list the tables:

sqlite> .tables

Regular SQL works here as well:

sqlite> select * from some_table;

Replace some_table as appropriate.

Here's the cache of the page described by Greg Smith. In case that dies as well, the alter statement looks like this:

UPDATE pg_attribute SET atttypmod = 35+4
WHERE attrelid = 'TABLE1'::regclass
AND attname = 'COL1';

Where your table is TABLE1, the column is COL1 and you want to set it to 35 characters (the +4 is needed for legacy purposes according to the link, possibly the overhead referred to by A.H. in the comments).

Is it proper to "reach into" an object and use its dict property?

In general, I would say "no". However Namespace has struck me as over-engineered, possibly from when classes couldn't inherit from built-in types.

On the other hand, Namespace does present a task-oriented approach to argparse, and I can't think of a situation that would call for grabbing the __dict__, but the limits of my imagination are not the same as yours.

In general, when "Bad File Descriptor" is encountered, it means that the socket file descriptor you passed into the API is not valid, which has multiple possible reasons:

1. The fd is already closed somewhere.
2. The fd has a wrong value, which is inconsistent with the value obtained from socket() api

You can use the following:

plt.hold(True)

Calling

$state.go($state.current, {myParam: newValue}, {notify: false});

will still reload the controller, meaning you will lose state data.

To avoid it, simply declare the parameter as dynamic:

$stateProvider.state({
    name: 'myState',
    url: '/my_state?myParam',
    params: {
        myParam: {
          dynamic: true,    // <----------
        }
    },
    ...
});

Then you don't even need the notify, just calling

$state.go($state.current, {myParam: newValue})

suffices. Neato!

From the documentation:

When dynamic is true, changes to the parameter value will not cause the state to be entered/exited. The resolves will not be re-fetched, nor will views be reloaded.

This can be useful to build UI where the component updates itself when the param values change.

Sometimes if you are making a target via make files double check that all c files are named correctly with correct file structure.

Certificate must cover both www and non-www https. Some provider's certs cover both for www.xxxx.yyy, but only one for xxxx.yyy.

Turn on rewrites:

RewriteEngine On

Make all http use https:

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://xxx.yyy/$1 [L,R=301]

Make only www https use the non-www https:

RewriteCond %{SERVER_PORT} 443
RewriteCond %{HTTP_HOST} ^www[.].+$
RewriteRule ^(.*)$ https://xxxx.yyy/$1 [L,R=301]

Cannot be processing non-www https, otherwise a loop occurs.

In [L,R=301]:

1. L = If the rule was processed, don't process any more.
2. R=301 = Tells browser/robot to do a permanent redirect.

More generic

A more generic approach -- not port-dependant -- is:

RewriteCond %{HTTP_HOST} ^www\.
RewriteRule ^(.*)$ https://xxxx.yyy/$1 [R=301,QSA]

to make any url with www drop it.

RewriteCond %{HTTPS} !on
RewriteCond %{HTTPS} !1
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTP:X-Forwarded-SSL} !on
RewriteRule ^(.*)$ https://xxxx.yyy/$1 [R=301,QSA]

to force any non-https url, even for those system downstream from load-balancers that drop https, use https.

Note that I have not tested the forwarded options, so would appreciate feedback on any issues with them. Those lines could be left out if your system is not behind a load-balancer.

TO HTTP_HOST or not

You can use ${HTTP_HOST} to be part of the URL in the RewriteRule, or you can use your explicit canonical domain name text (xxxx.yyy above).

Specifying the domain name explicitly ensures that no slight-of-hand character-bending means are used in the user-supplied URL to possibly trick your site into doing something it might not be prepared for, or at least ensures that the proper domain name appears in the address bar, regardless of which URL string opened the page.

It might even help convert punycode-encoded domains to show the proper unicode characters in the address bar.

Query string parameters can be accepted simply by using an argument on the action - i.e.

public ActionResult Foo(string someValue, int someOtherValue) {...}

which will accept a query like .../someroute?someValue=abc&someOtherValue=123

Other than that, you can look at the request directly for more control.

Depending on your definition of "special character", I think "[^a-zA-Z0-9]" would probably do the trick. That would find anything that is not a small letter, a capital letter, or a digit.

Based on the answer I linked to in my comment above, this should work:

delete from
(
select pf.* From PRODUCTFILTERS pf 
where pf.id>=200 
And pf.rowid in 
  (
     Select rowid from PRODUCTFILTERS 
     inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID 
     And PRODUCTS.NAME= 'Mark'
  )
); 

or

delete from PRODUCTFILTERS where rowid in
(
select pf.rowid From PRODUCTFILTERS pf 
where pf.id>=200 
And pf.rowid in 
  (
     Select PRODUCTFILTERS.rowid from PRODUCTFILTERS 
     inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID 
     And PRODUCTS.NAME= 'Mark'
  )
); 

Since method public void setColorFilter(@ColorInt int color, @NonNull PorterDuff.Mode mode) is deprecated, I use such form:

progressBar.indeterminateDrawable.colorFilter =
            PorterDuffColorFilter(ContextCompat.getColor(this, R.color.black), PorterDuff.Mode.SRC_IN)

axis = 0 means up to down axis = 1 means left to right

sums[key] = lang_sets[key].iloc[:,1:].sum(axis=0)

Given example is taking sum of all the data in column == key.

I like to think about interfaces and implementations of interfaces. In C++ speak interface is pure virtual class. Destructor is part of the interface and expected to implemented. Therefore destructor should be pure virtual. How about constructor? Constructor is actually not part of the interface because object is always instantiated explicitly.

Try putting this into the top of your file (before any other output):

<?php

header('Content-Type: text/html; charset=UTF-8');

?>

You can use a TextBox and set multiline to true and canEdit to false .

Even I come across same problem, not able to find active connections to my_db to kill it but still shows same error. I end up disconnecting all possible SSMS connections for any database on the Server, create a new connection from SSMS and change it to Multi user.

USE MASTER;

Note: This seems to be a possible bug in SQL Server 2005!

Use

const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");

directory.clear(); // <--

            break;
        }

SEE THIS EXAMPLE:The code example calculates the number of days in a particular month:

class SwitchDemo {
    public static void main(String[] args) {

        int month = 2;
        int year = 2000;
        int numDays = 0;

        switch (month) {
            case 1:
            case 3:
            case 5:
            case 7:
            case 8:
            case 10:
            case 12:
                numDays = 31;
                break;
            case 4:
            case 6:
            case 9:
            case 11:
                numDays = 30;
                break;
            case 2:
                if (((year % 4 == 0) && 
                     !(year % 100 == 0))
                     || (year % 400 == 0))
                    numDays = 29;
                else
                    numDays = 28;
                break;
            default:
                System.out.println("Invalid month.");
                break;
        }
        System.out.println("Number of Days = "
                           + numDays);
    }
}

This is the output from the code:

Number of Days = 29

FALLTHROUGH:

Another point of interest is the break statement. Each break statement terminates the enclosing switch statement. Control flow continues with the first statement following the switch block. The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered.

EXAMPLE CODE:

public class SwitchFallThrough {

    public static void main(String[] args) {
        java.util.ArrayList<String> futureMonths =
            new java.util.ArrayList<String>();

        int month = 8;

        switch (month) {
            case 1:  futureMonths.add("January");
            case 2:  futureMonths.add("February");
            case 3:  futureMonths.add("March");
            case 4:  futureMonths.add("April");
            case 5:  futureMonths.add("May");
            case 6:  futureMonths.add("June");
            case 7:  futureMonths.add("July");
            case 8:  futureMonths.add("August");
            case 9:  futureMonths.add("September");
            case 10: futureMonths.add("October");
            case 11: futureMonths.add("November");
            case 12: futureMonths.add("December");
            default: break;
        }

        if (futureMonths.isEmpty()) {
            System.out.println("Invalid month number");
        } else {
            for (String monthName : futureMonths) {
               System.out.println(monthName);
            }
        }
    }
}

This is the output from the code:

August
September
October
November
December

Using Strings in switch Statements

In Java SE 7 and later, you can use a String object in the switch statement's expression. The following code example, , displays the number of the month based on the value of the String named month:

public class StringSwitchDemo {

    public static int getMonthNumber(String month) {

        int monthNumber = 0;

        if (month == null) {
            return monthNumber;
        }

        switch (month.toLowerCase()) {
            case "january":
                monthNumber = 1;
                break;
            case "february":
                monthNumber = 2;
                break;
            case "march":
                monthNumber = 3;
                break;
            case "april":
                monthNumber = 4;
                break;
            case "may":
                monthNumber = 5;
                break;
            case "june":
                monthNumber = 6;
                break;
            case "july":
                monthNumber = 7;
                break;
            case "august":
                monthNumber = 8;
                break;
            case "september":
                monthNumber = 9;
                break;
            case "october":
                monthNumber = 10;
                break;
            case "november":
                monthNumber = 11;
                break;
            case "december":
                monthNumber = 12;
                break;
            default: 
                monthNumber = 0;
                break;
        }

        return monthNumber;
    }

    public static void main(String[] args) {

        String month = "August";

        int returnedMonthNumber =
            StringSwitchDemo.getMonthNumber(month);

        if (returnedMonthNumber == 0) {
            System.out.println("Invalid month");
        } else {
            System.out.println(returnedMonthNumber);
        }
    }
}

The output from this code is 8.

Alternatively, you may use FillDown

Range("M3") = "=G3&"",""&L3": Range("M3:M" & LastRow).FillDown

You could do something like this:

//outside of main
namespace A
{
    enum A
    {
        a = 0,
        b = 69,
        c = 666
    };
};

//in main:

A::A a = A::c;
std::cout << a << std::endl;

Use this way to delete only one side

    @ManyToOne(cascade=CascadeType.PERSIST, fetch = FetchType.LAZY)
//  @JoinColumn(name = "qid")
    @JoinColumn(name = "qid", referencedColumnName = "qid", foreignKey = @ForeignKey(name = "qid"), nullable = false)
    // @JsonIgnore
    @JsonBackReference
    private QueueGroup queueGroup;

Try this from bs4 import BeautifulSoup

This might be a problem with Beautiful Soup, version 4, and the beta days. I just read this from the homepage.

You have an extra closing } in your function.

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        }        // <== remove this brace
    }, false);
};

You really should be using something like JSHint or JSLint to help find these things. These tools integrate with many editors and IDEs, or you can just paste a code fragment into the above web sites and ask for an analysis.

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.

Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.

Possibly every remotely modern compiler implements #pragma pack which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)

From C99 §6.7.2.1:

12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.

13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.

The exact answer to the question is: yes, you can use an arbitrary value for the boundary parameter, given it does not exceed 70 bytes in length and consists only of 7-bit US-ASCII (printable) characters.

If you are using one of multipart/* content types, you are actually required to specify the boundary parameter in the Content-Type header, otherwise the server (in the case of an HTTP request) will not be able to parse the payload.

You probably also want to set the charset parameter to UTF-8 in your Content-Type header, unless you can be absolutely sure that only US-ASCII charset will be used in the payload data.

A few relevant excerpts from the RFC2046:

• 4.1.2. Charset Parameter:

  Unlike some other parameter values, the values of the charset parameter are NOT case sensitive. The default character set, which must be assumed in the absence of a charset parameter, is US-ASCII.

• 5.1. Multipart Media Type

  As stated in the definition of the Content-Transfer-Encoding field [RFC 2045], no encoding other than "7bit", "8bit", or "binary" is permitted for entities of type "multipart". The "multipart" boundary delimiters and header fields are always represented as 7bit US-ASCII in any case (though the header fields may encode non-US-ASCII header text as per RFC 2047) and data within the body parts can be encoded on a part-by-part basis, with Content-Transfer-Encoding fields for each appropriate body part.

  The Content-Type field for multipart entities requires one parameter, "boundary". The boundary delimiter line is then defined as a line consisting entirely of two hyphen characters ("-", decimal value 45) followed by the boundary parameter value from the Content-Type header field, optional linear whitespace, and a terminating CRLF.

  Boundary delimiters must not appear within the encapsulated material, and must be no longer than 70 characters, not counting the two leading hyphens.

  The boundary delimiter line following the last body part is a distinguished delimiter that indicates that no further body parts will follow. Such a delimiter line is identical to the previous delimiter lines, with the addition of two more hyphens after the boundary parameter value.

Here is an example using an arbitrary boundary:

Content-Type: multipart/form-data; charset=utf-8; boundary="another cool boundary"

--another cool boundary
Content-Disposition: form-data; name="foo"

bar
--another cool boundary
Content-Disposition: form-data; name="baz"

quux
--another cool boundary--

I recomend library assertj-core to handle exception in junit test

In java 8, like this:

//given

//when
Throwable throwable = catchThrowable(() -> anyService.anyMethod(object));

//then
AnyException anyException = (AnyException) throwable;
assertThat(anyException.getMessage()).isEqualTo("........");
assertThat(exception.getCode()).isEqualTo(".......);

It is changed to : from PIL.Image import core as image for new versions.

Follow this steps:

-Build
-Generate Signed Apk
-Create new

Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

Below mechanism helps in redirecting multiple lines to file. Keep complete string under " so that we can redirect values of the variable.

#!/bin/bash
kernel="2.6.39"
echo "line 1, ${kernel}
line 2," > a.txt
echo 'line 2, ${kernel}
line 2,' > b.txt

Content of a.txt is

line 1, 2.6.39
line 2,

Content of b.txt is

line 2, ${kernel}
line 2,

Most performant would, I guess, be using the listIterator method and do a reverse iteration:

for (ListIterator<E> iter = list.listIterator(list.size()); iter.hasPrevious();){
    if (weWantToDelete(iter.previous()))  iter.remove();
}

Edit: Much later, one might also want to add the Java 8 way of removing elements from a list (or any collection!) using a lambda or method reference. An in-place filter for collections, if you like:

list.removeIf(e -> e.isBad() && e.shouldGoAway());

This is probably the best way to clean up a collection. Since it uses internal iteration, the collection implementation could take shortcuts to make it as fast as possible (for ArrayLists, it could minimize the amount of copying needed).

In my particular case the function was actually missing. The error message is the same. I am using the Postgresql plugin PostGIS and I had to reinstall that for whatever reason.

On Linux, I often use curl with the --head parameter. It is available for several operating systems, including Windows.

[edit] related to the answer below, gknw.net is currently down as of February 23 2012. Check curl.haxx.se for updated info.

For end of line use:

git diff --ignore-space-at-eol

Instead of what are you using currently:

git diff -w (--ignore-all-space)

For start of line... you are out of luck if you want a built in solution.

However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".

Keeping the below statements in head tag fixed this issue

To have font variation working correctly, I had to reverse the order of @font-face in CSS.

@font-face {

    font-weight: bold;

}
 @font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono.ttf");
}

version 4.0

$('#d').val('').trigger('change');

This is the correct solution from now on according to deprecated message thrown in debug mode: "The select2("val") method has been deprecated and will be removed in later Select2 versions. Use $element.val() instead"

To downplay the "magic" of this issue a little bit. You need an Internet connection after you make those changes. If for some reason required libraries cannot by downloaded, instead of giving an appropriate message (like "Failed to fetch libraries") you will simply get the same build error. Was struggling with this for an hour before realizing that my company's VPN blocked the repo.

Something like the standard Collection.toArray(T[]) should do what you need (note that ArrayList implements Collection):

TypeA[] array = a.toArray(new TypeA[a.size()]);

On a side note, you should consider defining a to be of type List<TypeA> rather than ArrayList<TypeA>, this avoid some implementation specific definition that may not really be applicable for your application.

Also, please see this question about the use of a.size() instead of 0 as the size of the array passed to a.toArray(TypeA[])

#include <windows.h>

double PCFreq = 0.0;
__int64 CounterStart = 0;

void StartCounter()
{
    LARGE_INTEGER li;
    if(!QueryPerformanceFrequency(&li))
    cout << "QueryPerformanceFrequency failed!\n";

    PCFreq = double(li.QuadPart)/1000.0;

    QueryPerformanceCounter(&li);
    CounterStart = li.QuadPart;
}
double GetCounter()
{
    LARGE_INTEGER li;
    QueryPerformanceCounter(&li);
    return double(li.QuadPart-CounterStart)/PCFreq;
}

int main()
{
    StartCounter();
    Sleep(1000);
    cout << GetCounter() <<"\n";
    return 0;
}

This program should output a number close to 1000 (windows sleep isn't that accurate, but it should be like 999).

The StartCounter() function records the number of ticks the performance counter has in the CounterStart variable. The GetCounter() function returns the number of milliseconds since StartCounter() was last called as a double, so if GetCounter() returns 0.001 then it has been about 1 microsecond since StartCounter() was called.

If you want to have the timer use seconds instead then change

PCFreq = double(li.QuadPart)/1000.0;

to

PCFreq = double(li.QuadPart);

or if you want microseconds then use

PCFreq = double(li.QuadPart)/1000000.0;

But really it's about convenience since it returns a double.

Older version of Express use app.use(express.json()) or bodyParser.json() read more about bodyParser middleware

On latest version of express we could simply use res.json()

const express = require('express'),
    port = process.env.port || 3000,
    app = express()

app.get('/', (req, res) => res.json({key: "value"}))

app.listen(port, () => console.log(`Server start at ${port}`))

Parsing dates is a pain in JavaScript as there's no extensive native support. However you could do something like the following by relying on the Date(year, month, day [, hour, minute, second, millisecond]) constructor signature of the Date object.

var dateString = '17-09-2013 10:08',
    dateTimeParts = dateString.split(' '),
    timeParts = dateTimeParts[1].split(':'),
    dateParts = dateTimeParts[0].split('-'),
    date;

date = new Date(dateParts[2], parseInt(dateParts[1], 10) - 1, dateParts[0], timeParts[0], timeParts[1]);

console.log(date.getTime()); //1379426880000
console.log(date); //Tue Sep 17 2013 10:08:00 GMT-0400

You could also use a regular expression with capturing groups to parse the date string in one line.

var dateParts = '17-09-2013 10:08'.match(/(\d+)-(\d+)-(\d+) (\d+):(\d+)/);

console.log(dateParts); // ["17-09-2013 10:08", "17", "09", "2013", "10", "08"]

Yes, you should think of defining both your functions in a Class, and making word a member. This is cleaner :

class Spam:
    def oneFunction(self,lists):
        category=random.choice(list(lists.keys()))
        self.word=random.choice(lists[category])

    def anotherFunction(self):
        for letter in self.word:              
            print("_", end=" ")

Once you make a Class you have to Instantiate it to an Object and access the member functions

s = Spam()
s.oneFunction(lists)
s.anotherFunction()

Another approach would be to make oneFunction return the word so that you can use oneFunction instead of word in anotherFunction

>>> def oneFunction(lists):
        category=random.choice(list(lists.keys()))
        return random.choice(lists[category])

    
>>> def anotherFunction():
        for letter in oneFunction(lists):              
            print("_", end=" ")

And finally, you can also make anotherFunction, accept word as a parameter which you can pass from the result of calling oneFunction

>>> def anotherFunction(words):
        for letter in words:              
            print("_",end=" ")
>>> anotherFunction(oneFunction(lists))

Change URL behavior to "Dynamic".

A subtle problem causing even print to fail is having your environment variables set wrong, eg. here LC_ALL set to "C". In Debian they discourage setting it: Debian wiki on Locale

$ echo $LANG
en_US.utf8
$ echo $LC_ALL 
C
$ python -c "print (u'voil\u00e0')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe0' in position 4: ordinal not in range(128)
$ export LC_ALL='en_US.utf8'
$ python -c "print (u'voil\u00e0')"
voilà
$ unset LC_ALL
$ python -c "print (u'voil\u00e0')"
voilà

.NET is seeing an invalid SSL certificate on the other end of the connection. There is a workaround for it, but obviously not recommended for production code:

// Put this somewhere that is only once - like an initialization method
ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateCertificate);
...

static bool ValidateCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
   return true;
}

Just had the same problem - app was being installed OK, but won't run from Xcode with the "process launch failed: failed to get the task for process".

Turns out my development certificate expired during the night. Regenerating the certificate and the provisioning profiles solved the problem.

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.

Also, if your table has no ID column, or sorting by id doesn't return you the last row, you can always use sqlite schema native 'rowid' field.

SELECT column 
FROM table 
WHERE rowid = (SELECT MAX(rowid) FROM table);

Merge two different eloquent collections into one and some objects happen to have the same id, one will overwrite the other. Use push() method instead or rethink your approach to the problem to avoid that. Refer to web

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

In package.json set flag --base-href to relative path:

"script": {
    "build": "ng build --base-href ./"
}

Wouldn't you be better off with

<asp:HyperLink ID="HyperLink1" runat="server" 
            NavigateUrl="CMS_1.aspx" 
            Target="_blank">
    Click here
</asp:HyperLink>

Because, to replicate your desired behavior on an asp:Button, you have to call window.open on the OnClientClick event of the button which looks a lot less cleaner than the above solution. Plus asp:HyperLink is there to handle scenarios like this.

If you want to replicate this using an asp:Button, do this.

<asp:Button ID="btn" runat="Server" 
        Text="SUBMIT"
        OnClientClick="javascript:return openRequestedPopup();"/>

JavaScript function.

var windowObjectReference;

function openRequestedPopup() {
    windowObjectReference = window.open("CMS_1.aspx",
              "DescriptiveWindowName",
              "menubar=yes,location=yes,resizable=yes,scrollbars=yes,status=yes");
}

My take:

public static class SocketExtensions
{
    /// <summary>
    /// Connects the specified socket.
    /// </summary>
    /// <param name="socket">The socket.</param>
    /// <param name="endpoint">The IP endpoint.</param>
    /// <param name="timeout">The timeout.</param>
    public static void Connect(this Socket socket, EndPoint endpoint, TimeSpan timeout)
    {
        var result = socket.BeginConnect(endpoint, null, null);

        bool success = result.AsyncWaitHandle.WaitOne(timeout, true);
        if (success)
        {
            socket.EndConnect(result);
        }
        else
        {
            socket.Close();
            throw new SocketException(10060); // Connection timed out.
        }
    }
}

For my use (node names with xy positions) I found @user4179775's answer to the most helpful / intuitive:

import pandas as pd

df = pd.read_csv('glycolysis_nodes_xy.tsv', sep='\t')

df.head()
    nodes    x    y
0  c00033  146  958
1  c00031  601  195
...

xy_dict_list=dict([(i,[a,b]) for i, a,b in zip(df.nodes, df.x,df.y)])

xy_dict_list
{'c00022': [483, 868],
 'c00024': [146, 868],
 ... }

xy_dict_tuples=dict([(i,(a,b)) for i, a,b in zip(df.nodes, df.x,df.y)])

xy_dict_tuples
{'c00022': (483, 868),
 'c00024': (146, 868),
 ... }

Addendum

I later returned to this issue, for other, but related, work. Here is an approach that more closely mirrors the [excellent] accepted answer.

node_df = pd.read_csv('node_prop-glycolysis_tca-from_pg.tsv', sep='\t')

node_df.head()
   node  kegg_id kegg_cid            name  wt  vis
0  22    22       c00022   pyruvate        1   1
1  24    24       c00024   acetyl-CoA      1   1
...

Convert Pandas dataframe to a [list], {dict}, {dict of {dict}}, ...

Per accepted answer:

node_df.set_index('kegg_cid').T.to_dict('list')

{'c00022': [22, 22, 'pyruvate', 1, 1],
 'c00024': [24, 24, 'acetyl-CoA', 1, 1],
 ... }

node_df.set_index('kegg_cid').T.to_dict('dict')

{'c00022': {'kegg_id': 22, 'name': 'pyruvate', 'node': 22, 'vis': 1, 'wt': 1},
 'c00024': {'kegg_id': 24, 'name': 'acetyl-CoA', 'node': 24, 'vis': 1, 'wt': 1},
 ... }

In my case, I wanted to do the same thing but with selected columns from the Pandas dataframe, so I needed to slice the columns. There are two approaches.

1. Directly:

(see: Convert pandas to dictionary defining the columns used fo the key values)

node_df.set_index('kegg_cid')[['name', 'wt', 'vis']].T.to_dict('dict')

{'c00022': {'name': 'pyruvate', 'vis': 1, 'wt': 1},
 'c00024': {'name': 'acetyl-CoA', 'vis': 1, 'wt': 1},
 ... }

2. "Indirectly:" first, slice the desired columns/data from the Pandas dataframe (again, two approaches),

node_df_sliced = node_df[['kegg_cid', 'name', 'wt', 'vis']]

or

node_df_sliced2 = node_df.loc[:, ['kegg_cid', 'name', 'wt', 'vis']]

that can then can be used to create a dictionary of dictionaries

node_df_sliced.set_index('kegg_cid').T.to_dict('dict')

{'c00022': {'name': 'pyruvate', 'vis': 1, 'wt': 1},
 'c00024': {'name': 'acetyl-CoA', 'vis': 1, 'wt': 1},
 ... }

Quoting from Books Online:

Local temporary tables are visible only in the current session; global temporary tables are visible to all sessions.

Temporary tables are automatically dropped when they go out of scope, unless explicitly dropped using DROP TABLE:

• A local temporary table created in a stored procedure is dropped automatically when the stored procedure completes. The table can be referenced by any nested stored procedures executed by the stored procedure that created the table. The table cannot be referenced by the process which called the stored procedure that created the table.
• All other local temporary tables are dropped automatically at the end of the current session.
• Global temporary tables are automatically dropped when the session that created the table ends and all other tasks have stopped referencing them. The association between a task and a table is maintained only for the life of a single Transact-SQL statement. This means that a global temporary table is dropped at the completion of the last Transact-SQL statement that was actively referencing the table when the creating session ended.

Are you trying to reference a user variable in system variables? Try echo %path% and the M2 should have been fully expanded to show the file path to your Maven directory. If it hasn't, then that's the problem.

To fix it, you should create a user variable called PATH and add your %M2% reference into there.

AFAIK you cannot use VBA Excel to create custom tab in the Excel ribbon. You can however hide/make visible a ribbon component using VBA. Additionally, the link that you mentioned above is for MS Project and not MS Excel.

I create tabs for my Excel Applications/Add-Ins using this free utility called Custom UI Editor.

Edit: To accommodate new request by OP

Tutorial

Here is a short tutorial as promised:

1. After you have installed the Custom UI Editor (CUIE), open it and then click on File | Open and select the relevant Excel File. Please ensure that the Excel File is closed before you open it via CUIE. I am using a brand new worksheet as an example.

   

2. Right click as shown in the image below and click on "Office 2007 Custom UI Part". It will insert the "customUI.xml"

   

3. Next Click on menu Insert | Sample XML | Custom Tab. You will notice that the basic code is automatically generated. Now you are all set to edit it as per your requirements.

   

4. Let's inspect the code

   

   label="Custom Tab": Replace "Custom Tab" with the name which you want to give your tab. For the time being let's call it "Jerome".

   The below part adds a custom button.

   <button id="customButton" label="Custom Button" imageMso="HappyFace" size="large" onAction="Callback" />
   

   imageMso: This is the image that will display on the button. "HappyFace" is what you will see at the moment. You can download more image ID's here.

   onAction="Callback": "Callback" is the name of the procedure which runs when you click on the button.

Demo

With that, let's create 2 buttons and call them "JG Button 1" and "JG Button 2". Let's keep happy face as the image of the first one and let's keep the "Sun" for the second. The amended code now looks like this:

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon startFromScratch="false">
<tabs>
<tab id="MyCustomTab" label="Jerome" insertAfterMso="TabView">
<group id="customGroup1" label="First Tab">
<button id="customButton1" label="JG Button 1" imageMso="HappyFace" size="large" onAction="Callback1" />
<button id="customButton2" label="JG Button 2" imageMso="PictureBrightnessGallery" size="large" onAction="Callback2" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>

Delete all the code which was generated in CUIE and then paste the above code in lieu of that. Save and close CUIE. Now when you open the Excel File it will look like this:

Now the code part. Open VBA Editor, insert a module, and paste this code:

Public Sub Callback1(control As IRibbonControl)

    MsgBox "You pressed Happy Face"

End Sub

Public Sub Callback2(control As IRibbonControl)

    MsgBox "You pressed the Sun"

End Sub

Save the Excel file as a macro enabled file. Now when you click on the Smiley or the Sun you will see the relevant message box:

Hope this helps!

I think much has already been said, about RSS vs VSZ. From an administrator/programmer/user perspective, when I design/code applications I am more concerned about the RSZ, (Resident memory), as and when you keep pulling more and more variables (heaped) you will see this value shooting up. Try a simple program to build malloc based space allocation in loop, and make sure you fill data in that malloc'd space. RSS keeps moving up. As far as VSZ is concerned, it's more of virtual memory mapping that linux does, and one of its core features derived out of conventional operating system concepts. The VSZ management is done by Virtual memory management of the kernel, for more info on VSZ, see Robert Love's description on mm_struct and vm_struct, which are part of basic task_struct data structure in kernel.

        double a,b;
        Console.WriteLine("istenen sayiyi sonuna .00 koyarak yaz");
        try
        {
            a = Convert.ToDouble(Console.ReadLine());
            b = a * Math.PI;
            Console.WriteLine("Sonuç " + b); 
        }
        catch (Exception)
        {
            Console.WriteLine("dönüstürme hatasi");
            throw;
        }

There is no difference - bool is simply an alias of System.Boolean.

In my job we have a system with a generic data structure that can be described as a tree. That means that recursion is a very effective technique to work with the data.

Solving it without recursion would require a lot of unnecessary code. The problem with recursion is that it is not easy to follow what happens. You really have to concentrate when following the flow of execution. But when it works the code is elegant and effective.

Also known as Frozen Binaries but not the same as as the output of a true compiler- they run byte code through a virtual machine (PVM). Run the same as a compiled program just larger because the program is being compiled along with the PVM. Py2exe can freeze standalone programs that use the tkinter, PMW, wxPython, and PyGTK GUI libraties; programs that use the pygame game programming toolkit; win32com client programs; and more. The Stackless Python system is a standard CPython implementation variant that does not save state on the C language call stack. This makes Python more easy to port to small stack architectures, provides efficient multiprocessing options, and fosters novel programming structures such as coroutines. Other systems of study that are working on future development: Pyrex is working on the Cython system, the Parrot project, the PyPy is working on replacing the PVM altogether, and of course the founder of Python is working with Google to get Python to run 5 times faster than C with the Unladen Swallow project. In short, py2exe is the easiest and Cython is more efficient for now until these projects improve the Python Virtual Machine (PVM) for standalone files.

There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/

There are much more hexeditors on Linux/Unix....

I use hexedit on Ubuntu

sudo apt-get install hexedit

The > selector matches direct children only, not descendants.

You want

div.test th, td, caption {}

or more likely

div.test th, div.test td, div.test caption {}

Edit:

The first one says

  div.test th, /* any <th> underneath a <div class="test"> */
  td,          /* or any <td> anywhere at all */
  caption      /* or any <caption> */

Whereas the second says

  div.test th,     /* any <th> underneath a <div class="test"> */
  div.test td,     /* or any <td> underneath a <div class="test"> */
  div.test caption /* or any <caption> underneath a <div class="test">  */

In your original the div.test > th says any <th> which is a **direct** child of <div class="test">, which means it will match <div class="test"><th>this</th></div> but won't match <div class="test"><table><th>this</th></table></div>

Well in JavaScript you can check two strings for values same as integers so yo can do this:

• "A" < "B"
• "A" == "B"
• "A" > "B"

And therefore you can make your own function that checks strings the same way as the strcmp().

So this would be the function that does the same:

function strcmp(a, b)
{   
    return (a<b?-1:(a>b?1:0));  
}

you might want to use the parseparams command in matlab; the usage would look like:

function output = wave(varargin);
% comments, etc
[reg, props] = parseparams(varargin);
ctrls = cell2struct(props(2:2:end),props(1:2:end),2);  %yes this is ugly!
a = reg{1};
b = reg{2};
%etc
fTrue = ctrl.fTrue;

You can also Parse the date for month date and year and then you can use the PHP function checkdate() which you can read about here: http://php.net/manual/en/function.checkdate.php

You can also try this one:

$date="2013-13-01";

if (preg_match("/^[0-9]{4}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1])$/",$date))
    {
        echo 'Date is valid';
    }else{
        echo 'Date is invalid';
    }

The code by @Android is very good but has few issues, namely:

1. Populating to ListView code needs to be moved to onReceive of BroadCastReceiver where only the result will be available. In the case result is obtained at 2nd attempt.
2. BroadCastReceiver needs to be unregistered after the results are obtained.
3. size = size -1 seems unnecessary.

Also as mentioned above, do not forget to add Wifi permissions in the AndroidManifest.xml

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

I just tried a bare-bones implementation and it just works:

public class Test {

    public static void main(String[] args) {
            JFrame frame = new JFrame("Hello");
            frame.setPreferredSize(new Dimension(200, 200));
            frame.add(new Board());
            frame.pack();
            frame.setVisible(true);
    }
}

public class Board extends JPanel {

    private Player player = new Player();

    public Board(){
        setBackground(Color.BLACK);
    }

    public void paintComponent(Graphics g){  
        super.paintComponent(g);
        g.setColor(Color.red);
        g.fillOval(player.getCenter().x, player.getCenter().y,
             player.getRadius(), player.getRadius());
    } 
}

public class Player {

    private Point center = new Point(50, 50);

    public Point getCenter() {
        return center;
    }

    private int radius = 10;

    public int getRadius() {
        return radius;
    }
}

@override
Widget build(BuildContext context) {
  return Theme(
    data: ThemeData(brightness: Brightness.dark),
    child: Scaffold()
    ....
  )
}

You can also send (POST) multiple params within {} and add it.

Example:

$http.post(config.url+'/api/assign-badge/', {employeeId:emp_ID,bType:selectedCat,badge:selectedBadge})
    .then(function(response) {
        NotificationService.displayNotification('Info', 'Successfully Assigned!', true);
    }, function(response) {
});

where employeeId, bType (Badge Catagory), and badge are three parameters.

replace it with index of the array.

array[index] = new_value;

To access another drive, type the drive's letter, followed by ":".

Then enter:

cd d:\windows\movie

I created a new namespace (and therefore folder) identical to the route to a controller (e.g. MvcApp/Test/SomeClasses.cs and MvcApp/Controllers/TestController.cs). This resulted also in a 403.14!

I know you asked for GET and POST but I will provide CRUD since others may need this just in case: (this was tested in Python 3.7)

#!/usr/bin/env python3
import http.client
import json

print("\n GET example")
conn = http.client.HTTPSConnection("httpbin.org")
conn.request("GET", "/get")
response = conn.getresponse()
data = response.read().decode('utf-8')
print(response.status, response.reason)
print(data)


print("\n POST example")
conn = http.client.HTTPSConnection('httpbin.org')
headers = {'Content-type': 'application/json'}
post_body = {'text': 'testing post'}
json_data = json.dumps(post_body)
conn.request('POST', '/post', json_data, headers)
response = conn.getresponse()
print(response.read().decode())
print(response.status, response.reason)


print("\n PUT example ")
conn = http.client.HTTPSConnection('httpbin.org')
headers = {'Content-type': 'application/json'}
post_body ={'text': 'testing put'}
json_data = json.dumps(post_body)
conn.request('PUT', '/put', json_data, headers)
response = conn.getresponse()
print(response.read().decode(), response.reason)
print(response.status, response.reason)


print("\n delete example")
conn = http.client.HTTPSConnection('httpbin.org')
headers = {'Content-type': 'application/json'}
post_body ={'text': 'testing delete'}
json_data = json.dumps(post_body)
conn.request('DELETE', '/delete', json_data, headers)
response = conn.getresponse()
print(response.read().decode(), response.reason)
print(response.status, response.reason)

Here is the full list of YouTube embedded player parameters.

Relevant info:

autoplay (supported players: AS3, AS2, HTML5) Values: 0 or 1. Default is 0. Sets whether or not the initial video will autoplay when the player loads.

loop (supported players: AS3, HTML5) Values: 0 or 1. Default is 0. In the case of a single video player, a setting of 1 will cause the player to play the initial video again and again. In the case of a playlist player (or custom player), the player will play the entire playlist and then start again at the first video.

Note: This parameter has limited support in the AS3 player and in IFrame embeds, which could load either the AS3 or HTML5 player. Currently, the loop parameter only works in the AS3 player when used in conjunction with the playlist parameter. To loop a single video, set the loop parameter value to 1 and set the playlist parameter value to the same video ID already specified in the Player API URL:

http://www.youtube.com/v/VIDEO_ID?version=3&loop=1&playlist=VIDEO_ID

Use the URL above in your embed code (append other parameters too).

If your goal is to deploy your Spring Boot application to AWS, Boxfuse gives you a very easy solution.

All you need to do is:

boxfuse run my-spring-boot-app-1.0.jar -env=prod

This will:

• Fuse a minimal OS image tailor-made for your app (about 100x smaller than a typical Linux distribution)
• Push it to a secure online repository
• Convert it into an AMI in about 30 seconds
• Create and configure a new Elastic IP or ELB
• Assign a new domain name to it
• Launch one or more instances based on your new AMI

All images are generated in seconds and are immutable. They can be run unchanged on VirtualBox (dev) and AWS (test & prod).

All updates are performed as zero-downtime blue/green deployments and you can also enable auto-scaling with just one command.

Boxfuse also understands your Spring Boot config will automatically configure security groups and ELB health checks based upon your application.properties.

Here is a tutorial to help you get started: https://boxfuse.com/getstarted/springboot

Or you could use:

android.os.SystemClock.sleep(checkEvery)

which has the advantage of not requiring a wrapping try ... catch.

You can do this with @Html.CheckBoxFor():

@Html.CheckBoxFor(m => m.AllowRating, new{@checked=true });

or you can also do this with a simple @Html.CheckBox():

@Html.CheckBox("AllowRating", true) ;

One of the Honeycomb samples refers to ?android:attr/actionBarSize

     //test if varibale exist

How about:

Random generator = new Random();
int i = 10 - generator.nextInt(10);

Try this

alter table TableName 
 add constraint df_ConstraintNAme 
 default getutcdate() for [Date]

example

create table bla (id int)

alter table bla add constraint dt_bla default 1 for id



insert bla default values

select * from bla

also make sure you name the default constraint..it will be a pain in the neck to drop it later because it will have one of those crazy system generated names...see also How To Name Default Constraints And How To Drop Default Constraint Without A Name In SQL Server

I tried many of the above suggestions, but simplest one worked. In my case it was the use of @CachelookUp for the web element caused the stale element exception. I guess after refreshing the page, the element reference not reloaded and failed to find the element. Disabling @CachelookUp line for the element worked.

    //Search button
    @FindBy(how=How.XPATH, using =".//input[@value='Search']")  
    //@CachelookUp
    WebElement BtnSearch;

Build.IS_DEBUGGABLE could be all right. It comes from "ro.debuggable"

I like to do it like old times. You just use a custom UITextField Class like this one:

//
//  ReadOnlyTextField.swift
//  MediFormulas
//
//  Created by Oscar Rodriguez on 6/21/17.
//  Copyright © 2017 Nica Code. All rights reserved.
//

import UIKit

class ReadOnlyTextField: UITextField {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    override init(frame: CGRect) {
        super.init(frame: frame)

        // Avoid keyboard to show up
        self.inputView = UIView()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        // Avoid keyboard to show up
        self.inputView = UIView()
    }

    override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        // Avoid cut and paste option show up
        if (action == #selector(self.cut(_:))) {
            return false
        } else if (action == #selector(self.paste(_:))) {
            return false
        }

        return super.canPerformAction(action, withSender: sender)
    }

}

Both works fine. But according to the Apache docs you should avoid using mod_rewrite for simple redirections, and use Redirect instead. So according to them, you should preferably do:

<VirtualHost *:80>
    ServerName www.example.com
    Redirect / https://www.example.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.com
    # ... SSL configuration goes here
</VirtualHost>

The first / after Redirect is the url, the second part is where it should be redirected.

You can also use it to redirect URLs to a subdomain: Redirect /one/ http://one.example.com/

I think a solution is to put count in back ticks

.filter("`count` >= 2")

http://mail-archives.us.apache.org/mod_mbox/spark-user/201507.mbox/%3C8E43A71610EAA94A9171F8AFCC44E351B48EDF@fmsmsx124.amr.corp.intel.com%3E

I'll add this in here as my problem had something todo with my virtualenv:

I hadn't activated my virtual environment and was trying to install my requirements, this ultimately led to my install failing and throwing this error message.

So make sure you activate your virtualenv!

Ryan's Solution @Ryan in swift code

use:

 func imageWithSize(image: UIImage,size: CGSize)->UIImage{
    if UIScreen.mainScreen().respondsToSelector("scale"){
        UIGraphicsBeginImageContextWithOptions(size,false,UIScreen.mainScreen().scale);
    }
    else
    {
         UIGraphicsBeginImageContext(size);
    }

    image.drawInRect(CGRectMake(0, 0, size.width, size.height));
    var newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

//Summon this function VVV
func resizeImageWithAspect(image: UIImage,scaledToMaxWidth width:CGFloat,maxHeight height :CGFloat)->UIImage
{
    let oldWidth = image.size.width;
    let oldHeight = image.size.height;

    let scaleFactor = (oldWidth > oldHeight) ? width / oldWidth : height / oldHeight;

    let newHeight = oldHeight * scaleFactor;
    let newWidth = oldWidth * scaleFactor;
    let newSize = CGSizeMake(newWidth, newHeight);

    return imageWithSize(image, size: newSize);
}

you could also specify multiple style values like this

$('#navigation ul li').css({'display': 'inline-block','background-color': '#ff0000', 'color': '#ffffff'});

Check this one It's hacky, simple as that:

• Set -prefix-appearance to none to remove the styles
• Use text-indent to "push" the content a bit to the right
• Finally, set text-overflow to an empty string. Everything that extends beyond it's width will become... nothing! And that includes the arrow.

Now you're free to style it any way you want :)

.selectParent {_x000D_
  width: 80px;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
.selectParent select {_x000D_
  text-indent: 1px;_x000D_
  text-overflow: '';_x000D_
  width: 100px;_x000D_
  -webkit-appearance: none;_x000D_
  -moz-appearance: none;_x000D_
  appearance: none;_x000D_
  padding: 2px 2px 2px 2px;_x000D_
  border: none;_x000D_
  background: transparent url("http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png") no-repeat 60px center;_x000D_
}

<div class="selectParent">_x000D_
  <select>_x000D_
    <option value="1">Option 1</option>_x000D_
    <option value="2">Option 2</option>_x000D_
  </select>_x000D_
</div>

In the colors.xml file, write in the code below:

I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:

function utf8_to_latin2($str)
{
    return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
    {
        mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
        "From: $form\r\n".
        "Reply-To: $reply\r\n".
        "X-Mailer: PHP/" . phpversion());
    }

I have made another mailer function, because apple device could not read well the previous version.

function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
    $s= "=?utf-8?b?".base64_encode($s)."?=";
    $headers = "MIME-Version: 1.0\r\n";
    $headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
    $headers.= "Content-Type: text/plain;charset=utf-8\r\n";
    $headers.= "Reply-To: $reply\r\n";  
    $headers.= "X-Mailer: PHP/" . phpversion();
    mail($to, $s, $body, $headers);
}

That's error of a module in pyinstaller. The stuff would be sth like this, right:

File "c:\users\p-stu\appdata\local\programs\python\python38-32\lib\site-packages\PyInstaller\utils\win32\icon.py", line 234, in CopyIcons
    except win32api.error as W32E:
AttrubuteError: module 'win32ctypes.pywin32.win32api' has no attribute 'error'

What you want to reach is that, I believe:

• cmd + O for classes.
• cmd + shift + O for files.
• cmd + alt + O for symbols. "wonderful shortcut!"

Besides shift + cmd + f for find in path && double shift to search anywhere. Play with those and you will know what satisfy your need.

I can confirm that the approach in the question is sufficient to trigger the images to be downloaded and cached (unless you have forbidden the browser from doing so via your response headers) in, at least:

• Chrome 74
• Safari 12
• Firefox 66
• Edge 17

To test this, I made a small webapp with several endpoints that each sleep for 10 seconds before serving a picture of a kitten. Then I added two webpages, one of which contained a <script> tag in which each of the kittens is preloaded using the preloadImage function from the question, and the other of which includes all the kittens on the page using <img> tags.

In all the browsers above, I found that if I visited the preloader page first, waited a while, and then went to the page with the <img> tags, my kittens rendered instantly. This demonstrates that the preloader successfully loaded the kittens into the cache in all browsers tested.

You can see or try out the application I used to test this at https://github.com/ExplodingCabbage/preloadImage-test.

Note in particular that this technique works in the browsers above even if the number of images being looped over exceeds the number of parallel requests that the browser is willing to make at a time, contrary to what Robin's answer suggests. The rate at which your images preload will of course be limited by how many parallel requests the browser is willing to send, but it will eventually request each image URL you call preloadImage() on.

Tried most of the answers here, I got the error with the PUTTY SSH Client with all possible constellations.

Once I switched to OpenSSH the error was gone (remove the Environment Variable GIT_SSH and restart the git bash).

I was using a new machine and newest git versions. On many other/older machines (AWS as well) it did work as expected with PUTTY as well without any git configuration.

We can add drawable .xml like below

Editing .sln and .csproj is not always that easy or desirable. Once you get the error list you can see what projects have missing packages (also, the References node usually indicate that there are missing assemblies unless packages are source code, resources, images, or just text-based ones).

Removing and then adding the packages is not a good idea unless you use the latest version of the package. Otherwise be prepared for surprises, not always pleasant ones.

If, say, the package is EntityFramework then from NuGet gallery you get the latest version which at the time of writing this comment it is 6.1.3.

So, maybe the safest way to handle the situation is to restore the missing packages one by one. Yes, a bit painful exercise but chasing subtle bugs due to different package version maybe much more unpleasant.

Having this said, and let again EntityFramework be the missing package, you can issue the following command in the Package-Manager Console:

PM> Install-Package EntityFramework -Version 6.0.1 

This will install the correct version, that is 6.0.1, that is the one that is specified in packages.config:

    <?xml version="1.0" encoding="utf-8"?>
    <packages>
      <package id="EntityFramework" version="6.0.1" targetFramework="net451" />
    </packages>

... or if you really want to use NOT IN you can use

SELECT * FROM match WHERE id NOT IN ( SELECT id FROM email WHERE id IS NOT NULL)

lenkan's answer is a great solution.

<div>
  {{ beep: <div>Beep</div>,
     boop: <div>Boop</div>
  }[greeting]}
</div>

If you need a default value, then you can even do

<div>
  {{ beep: <div>Beep</div>,
     boop: <div>Boop</div>
  }[greeting] || <div>Hello world</div>}
</div>

Alternatively, if that doesn't read well to you, then you can do something like

<div>
  { 
    rswitch(greeting, {
      beep: <div>Beep</div>,
      boop: <div>Boop</div>,
      default: <div>Hello world</div>
    }) 
  }
</div>

with

function rswitch (param, cases) {
  if (cases[param]) {
    return cases[param]
  } else {
    return cases.default
  }
}

The static keyword in Java means that the variable or function is shared between all instances of that class as it belongs to the type, not the actual objects themselves.

So if you have a variable: private static int i = 0; and you increment it (i++) in one instance, the change will be reflected in all instances. i will now be 1 in all instances.

Static methods can be used without instantiating an object.

The embedded code of youtube has autoplay off by default. Simply add autoplay=1at the end of "src" attribute. For example:

<iframe src="http://www.youtube.com/embed/xzvScRnF6MU?autoplay=1" width="960" height="447" frameborder="0" allowfullscreen></iframe>

Can be done in one line:

-- the following expression calculates ==> max(@val1, @val2)
SELECT 0.5 * ((@val1 + @val2) + ABS(@val1 - @val2)) 

Edit: If you're dealing with very large numbers you'll have to convert the value variables into bigint in order to avoid an integer overflow.

If you were running a 64 bit platform you would see x86_64 or something very similar in the output from uname -a

To get your specific machine hardware name run

uname -m

You can also call

getconf LONG_BIT

which returns either 32 or 64

One aspect that is missing in other answers. It's true that in general the pattern is:

• Goal of __str__: human-readable
• Goal of __repr__: unambiguous, possibly machine-readable via eval

Unfortunately, this differentiation is flawed, because the Python REPL and also IPython use __repr__ for printing objects in a REPL console (see related questions for Python and IPython). Thus, projects which are targeted for interactive console work (e.g., Numpy or Pandas) have started to ignore above rules and provide a human-readable __repr__ implementation instead.

I do not think that you can do this easily. you should consider this answer here:

How can I display a pdf document into a Webview?

basically you'll be able to see a pdf if it is hosted online via google documents, but not if you have it in your device (you'll need a standalone reader for that)

I think what you want is this:

last_list=[]
if p.last_name != None and p.last_name != "":
    last_list.append(p.last_name)
print last_list

Your current if statement:

if p.last_name == None or p.last_name == "":
    pass

Effectively never does anything. If p.last_name is none or the empty string, it does nothing inside the loop. If p.last_name is something else, the body of the if statement is skipped.

Also, it looks like your statement pan_list.append(p.last) is a typo, because I see neither pan_list nor p.last getting used anywhere else in the code you have posted.

$("#tabs").tabs({active: [0,2], disabled: [3], selected: 2});

Where Selected is used for open Particular Tab or Select Particular Tab on onload.

In Notepad++ you can select few lines and use CTRL+Q which will automaticaly make block comments for selected lines.

DML have to be committed or rollbacked. DDL cannot.

http://www.orafaq.com/faq/what_are_the_difference_between_ddl_dml_and_dcl_commands

You can switch auto-commit on and that's again only for DML. DDL are never part of transactions and therefore there is nothing like an explicit commit/rollback.

truncate is DDL and therefore commited implicitly.

Edit
I've to say sorry. Like @DCookie and @APC stated in the comments there exist sth like implicit commits for DDL. See here for a question about that on Ask Tom. This is in contrast to what I've learned and I am still a bit curious about.

Open up your DevTools and press F1 to access the settings. Look for the console section and check the checkbox for "Log XMLHttpRequests".

Now all of your ajax and other similar requests will be logged in the console.

I prefer this method because it usually allows me to see everything that I'm looking for in the console without having to go to the network tab.

In GNU libm, the implementation of sin is system-dependent. Therefore you can find the implementation, for each platform, somewhere in the appropriate subdirectory of sysdeps.

One directory includes an implementation in C, contributed by IBM. Since October 2011, this is the code that actually runs when you call sin() on a typical x86-64 Linux system. It is apparently faster than the fsin assembly instruction. Source code: sysdeps/ieee754/dbl-64/s_sin.c, look for __sin (double x).

This code is very complex. No one software algorithm is as fast as possible and also accurate over the whole range of x values, so the library implements several different algorithms, and its first job is to look at x and decide which algorithm to use.

• When x is very very close to 0, sin(x) == x is the right answer.

• A bit further out, sin(x) uses the familiar Taylor series. However, this is only accurate near 0, so...

• When the angle is more than about 7°, a different algorithm is used, computing Taylor-series approximations for both sin(x) and cos(x), then using values from a precomputed table to refine the approximation.

• When |x| > 2, none of the above algorithms would work, so the code starts by computing some value closer to 0 that can be fed to sin or cos instead.

• There's yet another branch to deal with x being a NaN or infinity.

This code uses some numerical hacks I've never seen before, though for all I know they might be well-known among floating-point experts. Sometimes a few lines of code would take several paragraphs to explain. For example, these two lines

double t = (x * hpinv + toint);
double xn = t - toint;

are used (sometimes) in reducing x to a value close to 0 that differs from x by a multiple of π/2, specifically xn × π/2. The way this is done without division or branching is rather clever. But there's no comment at all!

Older 32-bit versions of GCC/glibc used the fsin instruction, which is surprisingly inaccurate for some inputs. There's a fascinating blog post illustrating this with just 2 lines of code.

fdlibm's implementation of sin in pure C is much simpler than glibc's and is nicely commented. Source code: fdlibm/s_sin.c and fdlibm/k_sin.c

The modern approach in 2019 is using ES6 module type scripts.

<script type="module" src="..."></script>

By default, modules are loaded asynchronously and defered. i.e. you can place them anywhere and they will load in parallel and execute when the page finishes loading.

The differences between a script and a module are described here:

https://stackoverflow.com/a/53821485/731548

The execution of a module compared to a script is described here:

https://developers.google.com/web/fundamentals/primers/modules#defer

There's a couple of other tricks that Postgres offers for string matching (if that happens to be your DB):

ILIKE, which is a case insensitive LIKE match:

select * from people where name ilike 'JOHN'

Matches:

• John
• john
• JOHN

And if you want to get really mad you can use regular expressions:

select * from people where name ~ 'John.*'

Matches:

• John
• Johnathon

SHELL := /bin/bash
PATH := bin:$(PATH)

test all:
    x

I don't know if this is desired behavior or not.

In case it helps someone, if your variables have hyphens in them, you may see this error since hyphens are not allowed in variable names in Python and are used as subtraction operators.

Example:

my-variable = 5   # would result in 'SyntaxError: can't assign to operator'

public String missingChar(String str, int n) {
  String front = str.substring(0, n);

// Start this substring at n+1 to omit the char.
// Can also be shortened to just str.substring(n+1)
// which goes through the end of the string.

String back = str.substring(n+1, str.length());
  return front + back;
}

I had this issue after upgrading to .NET Framework 4.7.2. I found out that Nuget package for System.Net.Http is no longer recommended. Here are workarounds:

• Single-name references are removed by the SDK
• Nuget package for System.Net.Http on .NET Framework 4.7.2 and newer versions

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

Use router.back() directly to go back/route-back programmatic on vue-router.

Make sure your oracle services are running automatically. Just press Win+R. Type services.msc in textbox then press O to find oracle services.

In your PC name might be like OracleserviceXYZ. Right click on highlighted services.

Look for keys (first word of line) in file2 that are also in file1.
Step 1: fill array a with the first words of file 1:

awk '{a[$1];}' file1

Step 2: Fill array a and ignore file 2 in the same command. For this check the total number of records until now with the number of the current input file.

awk 'NR==FNR{a[$1]}' file1 file2

Step 3: Ignore actions that might come after } when parsing file 1

awk 'NR==FNR{a[$1];next}' file1 file2 

Step 4: print key of file2 when found in the array a

awk 'NR==FNR{a[$1];next} $1 in a{print $1}' file1 file2

For MySQL 5.7.11

Step-1: First get the Unique Key

Use this query to get it:

1.1) SHOW CREATE TABLE User;

In the last, it will be like this:

.....

.....

UNIQUE KEY UK_8bv559q1gobqoulqpitq0gvr6 (phoneNum)

.....

....

Step-2: Remove the Unique key by this query.

ALTER TABLE User DROP INDEX UK_8bv559q1gobqoulqpitq0gvr6;

Step-3: Check the table info, by this query:

DESC User;

This should show that the index is removed

Thats All.

First, your code does not contain a contact div, it has a contacts div!

In sidebar you have contact in the div at the bottom of the page you have contacts. I removed the final s for the code sample. (you also misspelled the projectslink id in the sidebar).

Second, take a look at some of the examples for click on the jQuery reference page. You have to use click like, object.click( function() { // Your code here } ); in order to bind a click event handler to the object.... Like in my example below. As an aside, you can also just trigger a click on an object by using it without arguments, like object.click().

Third, scrollTo is a plugin in jQuery. I don't know if you have the plugin installed. You can't use scrollTo() without the plugin. In this case, the functionality you desire is only 2 lines of code, so I see no reason to use the plugin.

Ok, now on to a solution.

The code below will scroll to the correct div if you click a link in the sidebar. The window does have to be big enough to allow scrolling:

// This is a functions that scrolls to #{blah}link
function goToByScroll(id) {
    // Remove "link" from the ID
    id = id.replace("link", "");
    // Scroll
    $('html,body').animate({
        scrollTop: $("#" + id).offset().top
    }, 'slow');
}

$("#sidebar > ul > li > a").click(function(e) {
    // Prevent a page reload when a link is pressed
    e.preventDefault();
    // Call the scroll function
    goToByScroll(this.id);
});

Live Example

( Scroll to function taken from here )

PS: Obviously you should have a compelling reason to go this route instead of using anchor tags <a href="#gohere">blah</a> ... <a name="gohere">blah title</a>

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

Why can't you use absolute positioning? Vertical-align does not work (except for tables). Make your container's position: relative. Then absolutely position the internal divs using bottom: 0; Should work like a charm.

EDIT By zoidberg (i will update the answer instead)

<div style="position:relative; border: 1px solid red;width: 40px; height: 40px;">
   <div style="border:1px solid green;position: absolute; bottom: 0; left: 0; width: 20px; height: 20px;"></div>
   <div style="border:1px solid blue;position: absolute; bottom: 0; left: 20px; width: 20px height: 20px;"></div>

The following are tried, tested and proven methods to check if a row exists.

(Some of which I use myself, or have used in the past).

Edit: I made an previous error in my syntax where I used mysqli_query() twice. Please consult the revision(s).

I.e.:

if (!mysqli_query($con,$query)) which should have simply read as if (!$query).

• I apologize for overlooking that mistake.

Side note: Both '".$var."' and '$var' do the same thing. You can use either one, both are valid syntax.

Here are the two edited queries:

$query = mysqli_query($con, "SELECT * FROM emails WHERE email='".$email."'");

    if (!$query)
    {
        die('Error: ' . mysqli_error($con));
    }

if(mysqli_num_rows($query) > 0){

    echo "email already exists";

}else{

    // do something

}

and in your case:

$query = mysqli_query($dbl, "SELECT * FROM `tblUser` WHERE email='".$email."'");

    if (!$query)
    {
        die('Error: ' . mysqli_error($dbl));
    }

if(mysqli_num_rows($query) > 0){

    echo "email already exists";

}else{

    // do something

}

You can also use mysqli_ with a prepared statement method:

$query = "SELECT `email` FROM `tblUser` WHERE email=?";

if ($stmt = $dbl->prepare($query)){

        $stmt->bind_param("s", $email);

        if($stmt->execute()){
            $stmt->store_result();

            $email_check= "";         
            $stmt->bind_result($email_check);
            $stmt->fetch();

            if ($stmt->num_rows == 1){

            echo "That Email already exists.";
            exit;

            }
        }
    }

Or a PDO method with a prepared statement:

<?php
$email = $_POST['email'];

$mysql_hostname = 'xxx';
$mysql_username = 'xxx';
$mysql_password = 'xxx';
$mysql_dbname = 'xxx';

try {
$conn= new PDO("mysql:host=$mysql_hostname;dbname=$mysql_dbname", $mysql_username, $mysql_password); 
     $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
     exit( $e->getMessage() );
}

// assuming a named submit button
if(isset($_POST['submit']))
    {

        try {
            $stmt = $conn->prepare('SELECT `email` FROM `tblUser` WHERE email = ?');
            $stmt->bindParam(1, $_POST['email']); 
            $stmt->execute();
            while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

            }
        }
        catch(PDOException $e) {
            echo 'ERROR: ' . $e->getMessage();
        }

    if($stmt->rowCount() > 0){
        echo "The record exists!";
    } else {
        echo "The record is non-existant.";
    }


    }
?>

• Prepared statements are best to be used to help protect against an SQL injection.

N.B.:

When dealing with forms and POST arrays as used/outlined above, make sure that the POST arrays contain values, that a POST method is used for the form and matching named attributes for the inputs.

• FYI: Forms default to a GET method if not explicity instructed.

Note: <input type = "text" name = "var"> - $_POST['var'] match. $_POST['Var'] no match.

• POST arrays are case-sensitive.

1. Check for correct method declaration

public static void main(String [ ] args)

2. Check netbeans project properties in Run > main Class

import scala.io.Source

object Demo {

  def main(args: Array[String]): Unit = {

    val ipfileStream = getClass.getResourceAsStream("/folder/a-words.txt")
    val readlines = Source.fromInputStream(ipfileStream).getLines
    readlines.foreach(readlines => println(readlines))

  }

}

I found the answer on the web:

Dim fsT As Object
Set fsT = CreateObject("ADODB.Stream")
fsT.Type = 2 'Specify stream type - we want To save text/string data.
fsT.Charset = "utf-8" 'Specify charset For the source text data.
fsT.Open 'Open the stream And write binary data To the object
fsT.WriteText "special characters: äöüß"
fsT.SaveToFile sFileName, 2 'Save binary data To disk

Certainly not as I expected...

You should trigger the animation to revert once it's completed w/ javascript.

  $(".item").live("animationend webkitAnimationEnd", function(){
    $(this).removeClass('animate');
  });

I Use simply for my app:

using IWshRuntimeLibrary; // > Ref > COM > Windows Script Host Object  
...   
private static void CreateShortcut()
    {
        string link = Environment.GetFolderPath( Environment.SpecialFolder.Desktop ) 
            + Path.DirectorySeparatorChar + Application.ProductName + ".lnk";
        var shell = new WshShell();
        var shortcut = shell.CreateShortcut( link ) as IWshShortcut;
        shortcut.TargetPath = Application.ExecutablePath;
        shortcut.WorkingDirectory = Application.StartupPath;
        //shortcut...
        shortcut.Save();
    }

Just build your String in HTML and set it:

String sourceString = "<b>" + id + "</b> " + name; 
mytextview.setText(Html.fromHtml(sourceString));

You need to add the new line character \n:

console.log('line one \nline two')

would display:

line one

line two

You can try hfexcel Human Friendly object-oriented python library based on XlsxWriter:

from hfexcel import HFExcel

hf_workbook = HFExcel.hf_workbook('example.xlsx', set_default_styles=False)

hf_workbook.add_style(
    "headline", 
    {
       "bold": 1,
        "font_size": 14,
        "font": "Arial",
        "align": "center"
    }
)

sheet1 = hf_workbook.add_sheet("sheet1", name="Example Sheet 1")

column1, _ = sheet1.add_column('headline', name='Column 1', width=2)
column1.add_row(data='Column 1 Row 1')
column1.add_row(data='Column 1 Row 2')

column2, _ = sheet1.add_column(name='Column 2')
column2.add_row(data='Column 2 Row 1')
column2.add_row(data='Column 2 Row 2')


column3, _ = sheet1.add_column(name='Column 3')
column3.add_row(data='Column 3 Row 1')
column3.add_row(data='Column 3 Row 2')

# In order to get a row with coordinates:
# sheet[column_index][row_index] => row
print(sheet1[1][1].data)
assert(sheet1[1][1].data == 'Column 2 Row 2')

hf_workbook.save()

   using (WebClient client = new WebClient())
   {

       byte[] response =
       client.UploadValues("http://dork.com/service", new NameValueCollection()
       {
           { "home", "Cosby" },
           { "favorite+flavor", "flies" }
       });

       string result = System.Text.Encoding.UTF8.GetString(response);
   }

You will need these includes:

using System;
using System.Collections.Specialized;
using System.Net;

If you're insistent on using a static method/class:

public static class Http
{
    public static byte[] Post(string uri, NameValueCollection pairs)
    {
        byte[] response = null;
        using (WebClient client = new WebClient())
        {
            response = client.UploadValues(uri, pairs);
        }
        return response;
    }
}

Then simply:

var response = Http.Post("http://dork.com/service", new NameValueCollection() {
    { "home", "Cosby" },
    { "favorite+flavor", "flies" }
});

the app domain is your domain name.

Try to use constructor procedure in your class.

Object.assign

is a key

Please take a look on this sample:

class Employee{
    firstname: string;
    lastname: string;
    birthdate: Date;
    maxWorkHours: number;
    department: string;
    permissions: string;
    typeOfEmployee: string;
    note: string;
    lastUpdate: Date;

    constructor(original: Object) { 
        Object.assign(this, original);
    }
}

let e = new Employee({
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 3,
    "username": "<anystring>",
    "permissions": "<anystring>",
    "lastUpdate": "<anydate>"
});
console.log(e);

To add on to the other answers here, if you would like to create a new object of a third different type with a where clause (e.g. one that is not your Entity Framework object) you can do this:

public IEnumerable<ThirdNonEntityClass> demoMethod(IEnumerable<int> property1Values)
{
    using(var entityFrameworkObjectContext = new EntityFrameworkObjectContext )
    {
        var result = entityFrameworkObjectContext.SomeClass
            .Join(entityFrameworkObjectContext.SomeOtherClass,
                sc => sc.property1,
                soc => soc.property2,
                (sc, soc) => new {sc, soc})
            .Where(s => propertyValues.Any(pvals => pvals == es.sc.property1)
            .Select(s => new ThirdNonEntityClass 
            {
                dataValue1 = s.sc.dataValueA,
                dataValue2 = s.soc.dataValueB
            })
            .ToList();
    }

    return result;

}    

Pay special attention to the intermediate object that is created in the Where and Select clauses.

Note that here we also look for any joined objects that have a property1 that matches one of the ones in the input list.

I know this is a bit more complex than what the original asker was looking for, but hopefully it will help someone.

Just in case none of the above options worked for anyone I fixed my instance of this error by noticing a corrupt entry in my App.Config due to a missing nuget package in the test project.

this.props.children should either be a ReactElement or an array of ReactElement, but not components.

To get the DOM nodes of the children elements, you need to clone them and assign them a new ref.

render() {
  return (
    <div>
      {React.Children.map(this.props.children, (element, idx) => {
        return React.cloneElement(element, { ref: idx });
      })}
    </div>
  );
}

You can then access the child components via this.refs[childIdx], and retrieve their DOM nodes via ReactDOM.findDOMNode(this.refs[childIdx]).

If you are using eclipse try:

Window > Preferences > Android > Launch

Default emulator options: -dns-server 8.8.8.8,8.8.4.4

Had same error with code:

X509Certificate2 mycert = new X509Certificate2(@"C:\certificate.crt");

Solved by adding password:

X509Certificate2 mycert = new X509Certificate2(@"C:\certificate.crt", "password");

First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

Or you can do something like:

Old versions Laravel.

Model::all()->take(10)->get();

Newer version Laravel.

Model::all()->take(10);

This is pretty late in the game, but when would you use JavaScript in an HTML Email? For example, at the company I currently work for (rhymes with Abodee), we use the lowest common denominator for most email marketing campaigns – and JavaScript is just not being used. Ever. Unless you are referring to some kind of pre-processing.

As mentioned in a related post: "Lotus Notes, Mozilla Thunderbird, Outlook Express, and Windows Live Mail all seem to support some sort of JavaScript execution. Nothing else does."

credit for path goes to this answer

SIDENOTE: I had a lot of fun trying to get this into my iPad after that. It worked however. Using Snow Leopard + Xcode 4.2 + iPad with IOS 5.1.1 :) - I used the iPhone configuration utility to get the app into the ipad (you have to add the app, then click on the device, then click "install" behind the app you just added in the "application library" of iphone configuration utility) and had to create a Distribution Provisioning Profile and get the WWDR certificate and finally change the build settings in Xcode after all the certificates were in place. See here

But after much fun I am now looking at my first app on my iPad :) - btw, for getting apps into the app store you need to create a app store Distribution Provisioning Profile, while for ad hoc installs like these you create an ad hoc one. There is a bit more to it, but I think these are the most important and tricky steps. Enjoy.

PS. Just remembered that you also have to set the build type (top left of Xcode) to "iOS device", otherwise it will never sign your application. So the path name above only has limited value: yes, it will have the .app file in it, but no you can't upload it (at least not using the iPhone configuration utility) since it is not code signed - you will get an "Could not copy validate signature" error. So change it to "iOS device" and build (remember to select the right certificates in the build section of Xcode as per the url info above). In that same build section, you can also set the "Installation Build Products Location" to a different path, so that you can determine where the .app (the one that is properly code signed) ends up.

The C++ syntax is like this:

class Bar : public Foo {
  // ...

  void printStuff() {
    Foo::printStuff(); // calls base class' function
  }
};

Use Math.round(), possibly in conjunction with MidpointRounding.AwayFromZero

eg:

Math.Round(1.2) ==> 1
Math.Round(1.5) ==> 2
Math.Round(2.5) ==> 2
Math.Round(2.5, MidpointRounding.AwayFromZero) ==> 3

Short answer

Use a TreeMap. This is precisely what it's for.

If this map is passed to you and you cannot determine the type, then you can do the following:

SortedSet<String> keys = new TreeSet<>(map.keySet());
for (String key : keys) { 
   String value = map.get(key);
   // do something
}

This will iterate across the map in natural order of the keys.

Longer answer

Technically, you can use anything that implements SortedMap, but except for rare cases this amounts to TreeMap, just as using a Map implementation typically amounts to HashMap.

For cases where your keys are a complex type that doesn't implement Comparable or you don't want to use the natural order then TreeMap and TreeSet have additional constructors that let you pass in a Comparator:

// placed inline for the demonstration, but doesn't have to be a lambda expression
Comparator<Foo> comparator = (Foo o1, Foo o2) -> {
        ...
    }

SortedSet<Foo> keys = new TreeSet<>(comparator);
keys.addAll(map.keySet());

Remember when using a TreeMap or TreeSet that it will have different performance characteristics than HashMap or HashSet. Roughly speaking operations that find or insert an element will go from O(1) to O(Log(N)).

In a HashMap, moving from 1000 items to 10,000 doesn't really affect your time to lookup an element, but for a TreeMap the lookup time will be about 3 times slower (assuming Log₂). Moving from 1000 to 100,000 will be about 6 times slower for every element lookup.

In Android Studio, go to app -> src -> main -> java -> com.example.username.projectname

Right click on com.example.username.projectname -> Activity -> ActivityType

Fill in the details of the New Android Activity and click Finish.

Viola! new activity added to the existing project.

Edit the httpd.conf file and replace the line DocumentRoot "/home/user/www" to your liked one.

The default DocumentRoot path will be different for windows [the above is for linux].

Get it from the FPU unit on chip instead:

    }
    return pi;
}

double PI = get_PI();

The reason may be that watcher is declared as local variable to a method and it is garbage collected when the method finishes. You should declare it as a class member. Try the following:

FileSystemWatcher watcher;

private void watch()
{
  watcher = new FileSystemWatcher();
  watcher.Path = path;
  watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                         | NotifyFilters.FileName | NotifyFilters.DirectoryName;
  watcher.Filter = "*.*";
  watcher.Changed += new FileSystemEventHandler(OnChanged);
  watcher.EnableRaisingEvents = true;
}

private void OnChanged(object source, FileSystemEventArgs e)
{
  //Copies file to another directory.
}

Just put ${yourpathtofile/folder}

PowerShell does not count spaces; to tell PowerShell to consider the whole path including spaces, add your path in between ${ & }.

I checked the source code you provided on GitHub. There were several mistakes / typos in the configuration.

In CustomerDbConfig / OrderDbConfig you should refer to customerEntityManager and packages should point at existing packages:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "customerEntityManager",
    transactionManagerRef = "customerTransactionManager",
    basePackages = {"com.mm.boot.multidb.repository.customer"})
public class CustomerDbConfig {

The packages to scan in customerEntityManager and orderEntityManager were both not pointing at proper package:

em.setPackagesToScan("com.mm.boot.multidb.model.customer");

Also the injection of proper EntityManagerFactory did not work. It should be:

@Bean(name = "customerTransactionManager")
public PlatformTransactionManager transactionManager(EntityManagerFactory customerEntityManager){

}

The above was causing the issue and the exception. While providing the name in a @Bean method you are sure you get proper EMF injected.

The last thing I have done was to disable to automatic configuration of JpaRepositories:

And with all fixes the application starts as you probably expect!

GlobalStrings.AddRange(localStrings);

Note: You cannot declare the list object using the interface (IList).
Documentation: List<T>.AddRange(IEnumerable<T>).

Define your .table and .cell height:100%;

    .table {
        display: table;
        height:100%;
    }

    .cell {
        border: 1px solid black;
        display: table-cell;
        vertical-align:top;
height: 100%;

    }

    .container {
        height: 100%;
        border: 10px solid green;

    }

Demo

Since 1.4 this is now possible with the * operator. When given two objects, it will merge them recursively. For example,

jq -s '.[0] * .[1]' file1 file2

Important: Note the -s (--slurp) flag, which puts files in the same array.

Would get you:

{
  "value1": 200,
  "timestamp": 1382461861,
  "value": {
    "aaa": {
      "value1": "v1",
      "value2": "v2",
      "value3": "v3",
      "value4": 4
    },
    "bbb": {
      "value1": "v1",
      "value2": "v2",
      "value3": "v3"
    },
    "ccc": {
      "value1": "v1",
      "value2": "v2"
    },
    "ddd": {
      "value3": "v3",
      "value4": 4
    }
  },
  "status": 200
}

If you also want to get rid of the other keys (like your expected result), one way to do it is this:

jq -s '.[0] * .[1] | {value: .value}' file1 file2

Or the presumably somewhat more efficient (because it doesn't merge any other values):

jq -s '.[0].value * .[1].value | {value: .}' file1 file2

There is also this tool you can use. It supports multi-events .ics file creation. It also supports timezone as well.

http://apps.marudot.com/ical/

You can use a tool like the TrIDNet - File Identifier to look for the Magic Number and other telltales, if the file format is in it's database it may tell you what it is for.

However searching the definitions did not turn up anything for the string "FLDB", but it checks more than magic numbers so it is worth a try.

If you are using Linux File is a command that will do a similar task.

The other thing to try is if you have access to the program that generated this file, there may be DLL's or EXE's from the database software that may contain meta information about the dll's creator which could give you a starting point for looking for software that can read the file outside of the program that originally created the .db file.

You should use a List for something like this, not an array. As a general rule of thumb, when you don't know how many elements you will add to an array before hand, use a List instead. Most would probably tackle this problem by using an ArrayList.

If you really can't use a List, then you'll probably have to use an array of some initial size (maybe 10?) and keep track of your array capacity versus how many elements you're adding, and copy the elements to a new, larger array if you run out of room (this is essentially what ArrayList does internally). Also note that, in the real world, you would never do it this way - you would use one of the standard classes that are made specifically for cases like this, such as ArrayList.

Using vlines:

import numpy as np
np.random.seed(5)
x = arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
p =  plot(x, y, "o")
vlines(70,100,250)

The basic call signatures are:

vlines(x, ymin, ymax)
hlines(y, xmin, xmax)

For a string of length 1 you can simply perform isdigit() or isalpha()

If your string length is greater than 1, you can make a function something like..

def isinteger(a):
    try:
        int(a)
        return True
    except ValueError:
        return False

Do you actually have the single quotes in your command? I don't think they are necessary. Plus, I think you also need --no-auth-cache and --non-interactive

Here is what I use (no single quotes)

--non-interactive --no-auth-cache --username XXXX --password YYYY

See the Client Credentials Caching documentation in the svnbook for more information.

Logs are set in your settings.py file. A new, default project, looks like this:

# A sample logging configuration. The only tangible logging
# performed by this configuration is to send an email to
# the site admins on every HTTP 500 error when DEBUG=False.
# See http://docs.djangoproject.com/en/dev/topics/logging for
# more details on how to customize your logging configuration.
LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        }
    },
    'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
    }
}

By default, these don't create log files. If you want those, you need to add a filename parameter to your handlers

    'applogfile': {
        'level':'DEBUG',
        'class':'logging.handlers.RotatingFileHandler',
        'filename': os.path.join(DJANGO_ROOT, 'APPNAME.log'),
        'maxBytes': 1024*1024*15, # 15MB
        'backupCount': 10,
    },

This will set up a rotating log that can get 15 MB in size and keep 10 historical versions.

In the loggers section from above, you need to add applogfile to the handlers for your application

'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
        'APPNAME': {
            'handlers': ['applogfile',],
            'level': 'DEBUG',
        },
    }

This example will put your logs in your Django root in a file named APPNAME.log

The error means that you are providing not as much data as the table wp_posts does contain columns. And now the DB engine does not know in which columns to put your data.

To overcome this you must provide the names of the columns you want to fill. Example:

insert into wp_posts (column_name1, column_name2)
values (1, 3)

Look up the table definition and see which columns you want to fill.

And insert means you are inserting a new record. You are not modifying an existing one. Use update for that.

pip is a command line tool, not Python syntax.

In other words, run the command in your console, not in the Python interpreter:

pip install beautifulsoup4

You may have to use the full path:

C:\Python27\Scripts\pip install beautifulsoup4

or even

C:\Python27\Scripts\pip.exe install beautifulsoup4

Windows will then execute the pip program and that will use Python to install the package.

Another option is to use the Python -m command-line switch to run the pip module, which then operates exactly like the pip command:

python -m pip install beautifulsoup4

or

python.exe -m pip install beautifulsoup4

Please note that I posted this answer before the accepted answer. It's not correct. It's just a step forward from the solution in the question. I have edited the accepted question to show both the author's implementation and the final implementation I had used.

Based on comments and the linked migration document, I've made a few changes to the code:

In template:

<input type="text" v-on:input="debounceInput" v-model="searchInput">

In script:

watch: {
  searchInput: function () {
    this.debounceInput();
  }
},

And the method that sets the filter key stays the same:

methods: {
  debounceInput: _.debounce(function () {
    this.filterKey = this.searchInput;
  }, 500)
}

This looks like there is one less call (just the v-model, and not the v-on:input).

Not that I know of, because all markdown references I am aware of, like this one, mention:

Cell content must be on one line only

You can try it with that Markdown Tables Generator (whose example looks like the one you mention in your question, so you may be aware of it already).

Pandoc

If you are using Pandoc’s markdown (which extends John Gruber’s markdown syntax on which the GitHub Flavored Markdown is based) you can use either grid_tables:

+---------------+---------------+--------------------+

or multiline_tables.

  Second    row                 5.0 Here's another one. Note
                                    the blank line between
                                    rows.

In jQuery, the fn property is just an alias to the prototype property.

The jQuery identifier (or $) is just a constructor function, and all instances created with it, inherit from the constructor's prototype.

A simple constructor function:

function Test() {
  this.a = 'a';
}
Test.prototype.b = 'b';

var test = new Test(); 
test.a; // "a", own property
test.b; // "b", inherited property

A simple structure that resembles the architecture of jQuery:

(function() {
  var foo = function(arg) { // core constructor
    // ensure to use the `new` operator
    if (!(this instanceof foo))
      return new foo(arg);
    // store an argument for this example
    this.myArg = arg;
    //..
  };

  // create `fn` alias to `prototype` property
  foo.fn = foo.prototype = {
    init: function () {/*...*/}
    //...
  };

  // expose the library
  window.foo = foo;
})();

// Extension:

foo.fn.myPlugin = function () {
  alert(this.myArg);
  return this; // return `this` for chainability
};

foo("bar").myPlugin(); // alerts "bar"

The problem can be solved with a media query and some math. Here's a solution for a portait orientation:

@media (max-device-aspect-ratio: 3/4) {
  height: calc(100vw * 1.333 - 9%);
}
@media (max-device-aspect-ratio: 2/3) {
  height: calc(100vw * 1.5 - 9%);
}
@media (max-device-aspect-ratio: 10/16) {
  height: calc(100vw * 1.6 - 9%);
}
@media (max-device-aspect-ratio: 9/16) {
  height: calc(100vw * 1.778 - 9%);
}

Since vh will change when the url bar dissapears, you need to determine the height another way. Thankfully, the width of the viewport is constant and mobile devices only come in a few different aspect ratios; if you can determine the width and the aspect ratio, a little math will give you the viewport height exactly as vh should work. Here's the process

1) Create a series of media queries for aspect ratios you want to target.

• use device-aspect-ratio instead of aspect-ratio because the latter will resize when the url bar dissapears

• I added 'max' to the device-aspect-ratio to target any aspect ratios that happen to follow in between the most popular. THey won't be as precise, but they will be only for a minority of users and will still be pretty close to the proper vh.

• remember the media query using horizontal/vertical , so for portait you'll need to flip the numbers

2) for each media query multiply whatever percentage of vertical height you want the element to be in vw by the reverse of the aspect ratio.

• Since you know the width and the ratio of width to height, you just multiply the % you want (100% in your case) by the ratio of height/width.

3) You have to determine the url bar height, and then minus that from the height. I haven't found exact measurements, but I use 9% for mobile devices in landscape and that seems to work fairly well.

This isn't a very elegant solution, but the other options aren't very good either, considering they are:

• Having your website seem buggy to the user,

• having improperly sized elements, or

• Using javascript for some basic styling,

The drawback is some devices may have different url bar heights or aspect ratios than the most popular. However, using this method if only a small number of devices suffer the addition/subtraction of a few pixels, that seems much better to me than everyone having a website resize when swiping.

To make it easier, I also created a SASS mixin:

@mixin vh-fix {
  @media (max-device-aspect-ratio: 3/4) {
    height: calc(100vw * 1.333 - 9%);
  }
  @media (max-device-aspect-ratio: 2/3) {
    height: calc(100vw * 1.5 - 9%);
  }
  @media (max-device-aspect-ratio: 10/16) {
    height: calc(100vw * 1.6 - 9%);
  }
  @media (max-device-aspect-ratio: 9/16) {
    height: calc(100vw * 1.778 - 9%);
  }
}

Parent: Car
Child: Figo
Car c1 = new Figo();

=====
Upcasting:-
Method: Object c1 will refer to Methods of Class (Figo - Method must be overridden) because class "Figo" is specified with "new".
Instance Variable: Object c1 will refer to instance variable of Declaration Class ("Car").

When Declaration class is parent and object is created of child then implicit casting happens which is "Upcasting".

======
Downcasting:-
Figo f1 = (Figo) c1; //
Method: Object f1 will refer to Method of Class (figo) as initial object c1 is created with class "Figo". but once down casting is done, methods which are only present in class "Figo" can also be referred by variable f1.
Instance Variable: Object f1 will not refer to instance variable of Declaration class of object c1 (declaration class for c1 is CAR) but with down casting it will refer to instance variables of class Figo.

======
Use: When Object is of Child Class and declaration class is Parent and Child class wants to access Instance variable of it's own class and not of parent class then it can be done with "Downcasting".

You can use encoding/binary's ByteOrder to do this for 16, 32, 64 bit types

Play

package main

import "fmt"
import "encoding/binary"

func main() {
    var mySlice = []byte{244, 244, 244, 244, 244, 244, 244, 244}
    data := binary.BigEndian.Uint64(mySlice)
    fmt.Println(data)
}

Iterating Objects

If your map keys is an object and not an string, you can iterate it using Freemarker.

1) Convert the map into a list in the controller:

List<Map.Entry<myObjectKey, myObjectValue>> convertedMap  = new ArrayList(originalMap.entrySet());

2) Iterate the map in the Freemarker template, accessing to the object in the Key and the Object in the Value:

<#list convertedMap as item>
    <#assign myObjectKey = item.getKey()/>
    <#assign myObjectValue = item.getValue()/>
    [...]
</#list>

There was a feature request for that in vscode repo. But it was marked as extension-candidate and closed. So, here is the extension: Indent One space

Unlike the answer below that tells you to use Ctrl+[ this extension indents code by ONE whtespace ???.

That's because your dat1 and dat2 variables are just strings.

You should parse them to get a Date object, for that format I always use the following function:

// parse a date in yyyy-mm-dd format
function parseDate(input) {
  var parts = input.match(/(\d+)/g);
  // new Date(year, month [, date [, hours[, minutes[, seconds[, ms]]]]])
  return new Date(parts[0], parts[1]-1, parts[2]); // months are 0-based
}

I use this function because the Date.parse(string) (or new Date(string)) method is implementation dependent, and the yyyy-MM-dd format will work on modern browser but not on IE, so I prefer doing it manually.

try this

 data => {
                this.results = [...this.results, ...data.results];
                this._next = data.next;
            }

I'd use minlog, personally. It's extremely simple, as the logging class is a few hundred lines of code.

Make sure that you run the SQL Server Configuration Manager snap-in as Administrator if UAC is enabled. Then right click the service and then click properties, change the start mode to enabled, then start it.

To expand on what Shimi has said, you should only be running your loop from 1 to the square root of n. Then to find the pair, do n / i, and this will cover the whole problem space.

As was also noted, this is a NP, or 'difficult' problem. Exhaustive search, the way you are doing it, is about as good as it gets for guaranteed answers. This fact is used by encryption algorithms and the like to help secure them. If someone were to solve this problem, most if not all of our current 'secure' communication would be rendered insecure.

Python code:

import math

def divisorGenerator(n):
    large_divisors = []
    for i in xrange(1, int(math.sqrt(n) + 1)):
        if n % i == 0:
            yield i
            if i*i != n:
                large_divisors.append(n / i)
    for divisor in reversed(large_divisors):
        yield divisor

print list(divisorGenerator(100))

Which should output a list like:

[1, 2, 4, 5, 10, 20, 25, 50, 100]

I had a similar error. This could be because you would have changed some contract setting on your config file after it was refrenced into you project. solution - Update the webservice reference on you VSstudio project or create a new proxy using svcutil.exe

After much aggravation, I discovered how to scroll in iframes on my ipad. The secret was to do a vertical finger swipe (single finger was fine) on the LEFT side of the iframe area (and maybe slightly outside of the border). On a laptop or PC, the scroll bar is on the right, so naturally, I spent of lot of time on my ipad experimenting with finger motions on the right side. Only when I tried the left side would the iframe scroll.
