Check for scale factor in touchove event then prevent touch event.

document.addEventListener('touchmove', function(event) {
    event = event.originalEvent || event;
    if(event.scale > 1) {
        event.preventDefault();
    }
}, false);

For those of you who still don't understand after reading @meda answer, here is my concise and complete explanation for this issue:

Let's say you have 2 Fragments, Fragment_A and Fragment_B which are auto-generated from the app. On the bottom part of your generated fragments, you're going to find this code:

public class Fragment_A extends Fragment {

    //rest of the code is omitted

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        public void onFragmentInteraction(Uri uri);
    }
}

public class Fragment_B extends Fragment {

    //rest of the code is omitted

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        public void onFragmentInteraction(Uri uri);
    }
}

To overcome the issue, you have to add onFragmentInteraction method into your activity, which in my case is named MainActivity2. After that, you need to implements all fragments in the MainActivity like this:

public class MainActivity2 extends ActionBarActivity
        implements Fragment_A.OnFragmentInteractionListener, 
                   Fragment_B.OnFragmentInteractionListener, 
                   NavigationDrawerFragment.NavigationDrawerCallbacks {
    //rest code is omitted

    @Override
    public void onFragmentInteraction(Uri uri){
        //you can leave it empty
    }
}

P.S.: In short, this method could be used for communicating between fragments. For those of you who want to know more about this method, please refer to this link.

I created a trim.strings () function to trim leading and/or trailing whitespace as:

# Arguments:    x - character vector
#            side - side(s) on which to remove whitespace 
#                   default : "both"
#                   possible values: c("both", "leading", "trailing")

trim.strings <- function(x, side = "both") { 
    if (is.na(match(side, c("both", "leading", "trailing")))) { 
      side <- "both" 
      } 
    if (side == "leading") { 
      sub("^\\s+", "", x)
      } else {
        if (side == "trailing") {
          sub("\\s+$", "", x)
    } else gsub("^\\s+|\\s+$", "", x)
    } 
} 

For illustration,

a <- c("   ABC123 456    ", " ABC123DEF          ")

# returns string without leading and trailing whitespace
trim.strings(a)
# [1] "ABC123 456" "ABC123DEF" 

# returns string without leading whitespace
trim.strings(a, side = "leading")
# [1] "ABC123 456    "      "ABC123DEF          "

# returns string without trailing whitespace
trim.strings(a, side = "trailing")
# [1] "   ABC123 456" " ABC123DEF"   

I needed a Month/Year picker for two fields (From & To) and when one was chosen the Max/Min was set on the other one...a la picking airline ticket dates. I was having issues setting the max and min...the dates of the other field would get erased. Thanks to several of the above posts...I finally figured it out. You have to set options and dates in a very specific order.

See this fiddle for the full solution: Month/Year Picker @ JSFiddle

Code:

var searchMinDate = "-2y";
var searchMaxDate = "-1m";
if ((new Date()).getDate() <= 5) {
    searchMaxDate = "-2m";
}
$("#txtFrom").datepicker({
    dateFormat: "M yy",
    changeMonth: true,
    changeYear: true,
    showButtonPanel: true,
    showAnim: "",
    minDate: searchMinDate,
    maxDate: searchMaxDate,
    showButtonPanel: true,
    beforeShow: function (input, inst) {
        if ((datestr = $("#txtFrom").val()).length > 0) {
            var year = datestr.substring(datestr.length - 4, datestr.length);
            var month = jQuery.inArray(datestr.substring(0, datestr.length - 5), "#txtFrom").datepicker('option', 'monthNamesShort'));
        $("#txtFrom").datepicker('option', 'defaultDate', new Date(year, month, 1));
                $("#txtFrom").datepicker('setDate', new Date(year, month, 1));
            }
        },
        onClose: function (input, inst) {
            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
            $("#txtFrom").datepicker('option', 'defaultDate', new Date(year, month, 1));
            $("#txtFrom").datepicker('setDate', new Date(year, month, 1));
            var to = $("#txtTo").val();
            $("#txtTo").datepicker('option', 'minDate', new Date(year, month, 1));
            if (to.length > 0) {
                var toyear = to.substring(to.length - 4, to.length);
                var tomonth = jQuery.inArray(to.substring(0, to.length - 5), $("#txtTo").datepicker('option', 'monthNamesShort'));
                $("#txtTo").datepicker('option', 'defaultDate', new Date(toyear, tomonth, 1));
                $("#txtTo").datepicker('setDate', new Date(toyear, tomonth, 1));
            }
        }
    });
    $("#txtTo").datepicker({
        dateFormat: "M yy",
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        showAnim: "",
        minDate: searchMinDate,
        maxDate: searchMaxDate,
        showButtonPanel: true,
        beforeShow: function (input, inst) {
            if ((datestr = $("#txtTo").val()).length > 0) {
                var year = datestr.substring(datestr.length - 4, datestr.length);
                var month = jQuery.inArray(datestr.substring(0, datestr.length - 5), $("#txtTo").datepicker('option', 'monthNamesShort'));
                $("#txtTo").datepicker('option', 'defaultDate', new Date(year, month, 1));
                $("#txtTo").datepicker('setDate', new Date(year, month, 1));
            }
        },
        onClose: function (input, inst) {
            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
            $("#txtTo").datepicker('option', 'defaultDate', new Date(year, month, 1));
            $("#txtTo").datepicker('setDate', new Date(year, month, 1));
            var from = $("#txtFrom").val();
            $("#txtFrom").datepicker('option', 'maxDate', new Date(year, month, 1));
            if (from.length > 0) {
                var fryear = from.substring(from.length - 4, from.length);
                var frmonth = jQuery.inArray(from.substring(0, from.length - 5), $("#txtFrom").datepicker('option', 'monthNamesShort'));
                $("#txtFrom").datepicker('option', 'defaultDate', new Date(fryear, frmonth, 1));
                $("#txtFrom").datepicker('setDate', new Date(fryear, frmonth, 1));
            }

        }
    });

Also add this to a style block as mentioned above:

.ui-datepicker-calendar { display: none !important; }

**to count char or string **

 string st = "asdfasdfasdfsadfasdf/asdfasdfas/dfsdfsdafsdfsd/fsadfasdf/dff";
        int count = 0;
        int location = 0;
       
        while (st.IndexOf("/", location + 1) > 0)
        {
                count++;
                location = st.IndexOf("/", location + 1);
        }
        MessageBox.Show(count.ToString());

I had the same problem, it was a missing manifest.json file, if not found the browser decide with orientation is best fit, if you don't specify the file or use a wrong path.

I fixed just calling the manifest.json correctly on html headers.

My html headers:

<meta name="application-name" content="App Name">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<link rel="manifest" href="manifest.json">
<meta name="msapplication-starturl" content="/">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="theme-color" content="#">
<meta name="msapplication-TileColor" content="#">
<meta name="msapplication-config" content="browserconfig.xml">
<link rel="icon" type="image/png" sizes="192x192" href="android-chrome-192x192.png">
<link rel="apple-touch-icon" sizes="180x180" href="apple-touch-icon.png">
<link rel="mask-icon" href="safari-pinned-tab.svg" color="#ffffff">
<link rel="shortcut icon" href="favicon.ico">

And the manifest.json file content:

{
  "display": "standalone",
  "orientation": "portrait",
  "start_url": "/",
  "theme_color": "#000000",
  "background_color": "#ffffff",
  "icons": [
  {
    "src": "android-chrome-192x192.png",
    "sizes": "192x192",
    "type": "image/png"
  }
}

To generate your favicons and icons use this webtool: https://realfavicongenerator.net/

My PWA Works great, hope it helps!

The short version: Arrays are mostly faster than objects. But there is no 100% correct solution.

Update 2017 - Test and Results

var a1 = [{id: 29938, name: 'name1'}, {id: 32994, name: 'name1'}];

var a2 = [];
a2[29938] = {id: 29938, name: 'name1'};
a2[32994] = {id: 32994, name: 'name1'};

var o = {};
o['29938'] = {id: 29938, name: 'name1'};
o['32994'] = {id: 32994, name: 'name1'};

for (var f = 0; f < 2000; f++) {
    var newNo = Math.floor(Math.random()*60000+10000);
    if (!o[newNo.toString()]) o[newNo.toString()] = {id: newNo, name: 'test'};
    if (!a2[newNo]) a2[newNo] = {id: newNo, name: 'test' };
    a1.push({id: newNo, name: 'test'});
}

Original Post - Explanation

There are some misconceptions in your question.

There are no associative arrays in Javascript. Only Arrays and Objects.

These are arrays:

var a1 = [1, 2, 3];
var a2 = ["a", "b", "c"];
var a3 = [];
a3[0] = "a";
a3[1] = "b";
a3[2] = "c";

This is an array, too:

var a3 = [];
a3[29938] = "a";
a3[32994] = "b";

It's basically an array with holes in it, because every array does have continous indexing. It's slower than arrays without holes. But iterating manually through the array is even slower (mostly).

This is an object:

var a3 = {};
a3[29938] = "a";
a3[32994] = "b";

Here is a performance test of three possibilities:

Lookup Array vs Holey Array vs Object Performance Test

An excellent read about these topics at Smashing Magazine: Writing fast memory efficient JavaScript

In java script calculate width using following code

var scrollX = $(window).width()*58/100;
var oTable = $('#reqAllRequestsTable').dataTable({
    "sScrollX": scrollX
    } );

You can also use setShowSoftInputOnFocus(boolean) directly on API 21+ or through reflection on API 14+:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    editText.setShowSoftInputOnFocus(false);
} else {
    try {
        final Method method = EditText.class.getMethod(
                "setShowSoftInputOnFocus"
                , new Class[]{boolean.class});
        method.setAccessible(true);
        method.invoke(editText, false);
    } catch (Exception e) {
        // ignore
    }
}

This is the easiest one , Just define a Function and then a Tkinter Label & Button . Pressing the Button changes the text in the label. The difference that you would when defining the Label is that use the text variable instead of text. Code is tested and working.

    from tkinter import *
    master = Tk()
    
    def change_text():
        my_var.set("Second click")
    
    my_var = StringVar()
    my_var.set("First click")
    label = Label(mas,textvariable=my_var,fg="red")
    button = Button(mas,text="Submit",command = change_text)
    button.pack()
    label.pack()
    
    master.mainloop()

If you can't get this information from DNS (e.g. you aren't authorized) then one alternative is to use Wolfram Alpha.

1. Enter the domain into the search box and run the search. (E.g. stackexchange.com)

2. In the 3rd section from the top (named "Web statistics for all of stackexchange.com") click Subdomains

3. In the Subdomains section click More

You will be able to see a list of sub-domains there. Although I suspect it does not show ALL sub-domains.

• Go to project path > where you located Java files and package
• Create new folders, for example com ? super_package ? activities
• Android Studio will refresh project structure
• Move all Java files to new folders
• Remove old folders
• Menu Edit ? Find ? Replace in path:
• Change old package name to new
• Change also in manifest and build gradle

Done!

First step: go to /etc/phpmyadmin/config.inc.php then uncomment lines where you find AllowNoPassword . Second step: login to your mysql default account

mysql -u root -p
use mysql;
update user set plugin="" where user='root';
flush privilege;

and that's all!

$(document).scrollTop(0); also works.

i had the same problem, my solution was apply the required attribute to all elements

<input type="checkbox" name="checkin_days[]" required="required" value="0" /><span class="w">S</span>
<input type="checkbox" name="checkin_days[]" required="required" value="1" /><span class="w">M</span>
<input type="checkbox" name="checkin_days[]" required="required" value="2" /><span class="w">T</span>
<input type="checkbox" name="checkin_days[]" required="required" value="3" /><span class="w">W</span>
<input type="checkbox" name="checkin_days[]" required="required" value="4" /><span class="w">T</span>
<input type="checkbox" name="checkin_days[]" required="required" value="5" /><span class="w">F</span>
<input type="checkbox" name="checkin_days[]" required="required" value="6" /><span class="w">S</span>

when the user check one of the elements i remove the required attribute from all elements:

var $checkedCheckboxes = $('#recurrent_checkin :checkbox[name="checkin_days[]"]:checked'),
    $checkboxes = $('#recurrent_checkin :checkbox[name="checkin_days[]"]');

$checkboxes.click(function() {

if($checkedCheckboxes.length) {
        $checkboxes.removeAttr('required');
    } else {
        $checkboxes.attr('required', 'required');
    }

 });

Sure, take a look at sys.version and sys.version_info.

For example, to check that you are running Python 3.x, use

import sys
if sys.version_info[0] < 3:
    raise Exception("Must be using Python 3")

Here, sys.version_info[0] is the major version number. sys.version_info[1] would give you the minor version number.

In Python 2.7 and later, the components of sys.version_info can also be accessed by name, so the major version number is sys.version_info.major.

See also How can I check for Python version in a program that uses new language features?

I'd suggest perl. (\d+.\d+.\d+.\d+) should probably do the trick.

EDIT: Just to make it more like a complete program, you could do something like the following (not tested):

#!/usr/bin/perl -w
use strict;

while (<>) {
    if (/(\d+\.\d+\.\d+\.\d+)/) {
        print "$1\n";
    }
}

This handles one IP per line. If you have more than one IPs per line, you need to use the /g option. man perlretut gives you a more detailed tutorial on regular expressions.

const str = "dGhpcyBpcyBiYXNlNjQgc3RyaW5n"
const encoded = new TextEncoder().encode(str) // is Uint8Array
const buf = encoded.buffer // is ArrayBuffer

This is the most stable (and easy) way to do it, and it works in all modern browsers:

.fullscreen {_x000D_
  position: fixed;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  bottom: 0;_x000D_
  right: 0;_x000D_
  overflow: auto;_x000D_
  background: lime; /* Just to visualize the extent */_x000D_
  _x000D_
}

<div class="fullscreen">_x000D_
  Suspendisse aliquam in ante a ornare. Pellentesque quis sapien sit amet dolor euismod congue. Donec non semper arcu. Sed tortor ante, cursus in dui vitae, interdum vestibulum massa. Suspendisse aliquam in ante a ornare. Pellentesque quis sapien sit amet dolor euismod congue. Donec non semper arcu. Sed tortor ante, cursus in dui vitae, interdum vestibulum massa.

</div>

_{Tested to work in Firefox, Chrome, Opera, Vivaldi, IE7+ (based on emulation in IE11).}

for method parameters you can use Objects.requireNonNull() like this: test(String str) { Objects.requireNonNull(str); } But this is only checked at runtime and throws an NPE if null. It is like a preconditions check. But that might be what you are looking for.

I think the answer may be easier to understand like this:

$('#empid').on('change',function() {_x000D_
  alert($(this).val());_x000D_
  console.log($(this).val());_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>_x000D_
<select id="empid" name="empname" multiple="multiple">_x000D_
  <option value="0">Potato</option>_x000D_
  <option value="1">Carrot</option>_x000D_
  <option value="2">Apple</option>_x000D_
  <option value="3">Raisins</option>_x000D_
  <option value="4">Peanut</option>_x000D_
</select>_x000D_
<br />_x000D_
Hold CTRL / CMD for selecting multiple fields

If you select "Carrot" and "Raisins" in the list, the output will be "1,3".

I like to use the syntax '1 MonthName 2015' for dates ex:

   WHERE aa.AuditDate>='1 September 2015'
     AND aa.AuditDate<='30 September 2015'

for dates

the mysqli_queryexcepts 2 parameters , first variable is mysqli_connectequivalent variable , second one is the query you have provided

$name1 = mysqli_connect(localhost,tdoylex1_dork,dorkk,tdoylex1_dork);

$name2 = mysqli_query($name1,"SELECT name FROM users ORDER BY RAND() LIMIT 1");

response.setContentType("application/json;charset=utf-8");

A little intro to dictionary

d={'a':'apple','b':'ball'}
d.keys()  # displays all keys in list
['a','b']
d.values() # displays your values in list
['apple','ball']
d.items() # displays your pair tuple of key and value
[('a','apple'),('b','ball')

Print keys,values method one

for x in d.keys():
    print x +" => " + d[x]

Another method

for key,value in d.items():
    print key + " => " + value

You can get keys using iter

>>> list(iter(d))
['a', 'b']

You can get value of key of dictionary using get(key, [value]):

d.get('a')
'apple'

If key is not present in dictionary,when default value given, will return value.

d.get('c', 'Cat')
'Cat'

For Android, change the app name from the Android folder. In the AndroidManifest.xml file, in folder android/app/src/main, let the android label refer to the name you prefer, for example,

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    <application
        `android:label="myappname"`
        // The rest of the code
    </application>
</manifest>

[ round(x,2) for x in [2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01]]

You can't add static methods to a type. You can only add (pseudo-)instance methods to an instance of a type.

The point of the this modifier is to tell the C# compiler to pass the instance on the left-side of the . as the first parameter of the static/extension method.

In the case of adding static methods to a type, there is no instance to pass for the first parameter.

I have written some extensions to accommodate almost any need.
There are extension overloads to feed with Separator, String.Format and IFormatProvider.

Example:

var array1 = new byte[] { 50, 51, 52, 53 };
var array2 = new double[] { 1.1111, 2.2222, 3.3333 };
var culture = CultureInfo.GetCultureInfo("ja-JP");

Console.WriteLine("Byte Array");
//Normal print 
Console.WriteLine(array1.StringJoin());
//Format to hex values
Console.WriteLine(array1.StringJoin("-", "0x{0:X2}"));
//Comma separated 
Console.WriteLine(array1.StringJoin(", "));
Console.WriteLine();

Console.WriteLine("Double Array");
//Normal print 
Console.WriteLine(array2.StringJoin());
//Format to Japanese culture
Console.WriteLine(array2.StringJoin(culture));
//Format to three decimals 
Console.WriteLine(array2.StringJoin(" ", "{0:F3}"));
//Format to Japanese culture and two decimals
Console.WriteLine(array2.StringJoin(" ", "{0:F2}", culture));
Console.WriteLine();

Console.ReadLine();

First of all, you do not have to develop any form yourself : phpMyAdmin, depending on its configuration (i.e. config.inc.php) will display an identification form, asking for a login and password.

To get that form, you should not use :

$cfg['Servers'][$i]['auth_type'] = 'config';

But you should use :

$cfg['Servers'][$i]['auth_type'] = 'cookie';

(At least, that's what I have on a server which prompts for login/password, using a form)

For more informations, you can take a look at the documentation :

• Using authentication modes
• Configuration, which states (quoting) :

'config' authentication ($auth_type = 'config') is the plain old way: username and password are stored in config.inc.php.

'cookie' authentication mode ($auth_type = 'cookie') as introduced in 2.2.3 allows you to log in as any valid MySQL user with the help of cookies.
Username and password are stored in cookies during the session and password is deleted when it ends.

If you are seeing this error in your self-hosted GitHub actions logs then it might be you are not using the latest git version supported by Github actions.

For knowing which version it is supported, go to actions/checkout logs and upgrade your server git version to the mentioned version or above this.

First check the value is checked

$("#ans").find("checkbox").each(function(){
    if ($(this).prop('checked')==true){ 
    var id = $(this).val()
    }
});

Else set the 0 value

I know it's a old quetion but i got the same problem and fix it like this:

First, Add Fragment1 to BackStack with a name (e.g "Frag1"):

frag = new Fragment1();

transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.detailFragment, frag);
transaction.addToBackStack("Frag1");
transaction.commit();

And then, Whenever you want to go back to Fragment1 (even after adding 10 fragments above it), just call popBackStackImmediate with the name:

getSupportFragmentManager().popBackStackImmediate("Frag1", 0);

Hope it will help someone :)

For MySql WorkBench, Please use below :

update emp as a
inner join department b on a.department_id=b.id
set a.department_name=b.name
where a.emp_id in (10,11,12); 

Here is a fast vectorized version of @Dimitri's solution if you have many values to search for (values can be multi-dimensional array):

#`values` should be sorted
def get_closest(array, values):
    #make sure array is a numpy array
    array = np.array(array)

    # get insert positions
    idxs = np.searchsorted(array, values, side="left")

    # find indexes where previous index is closer
    prev_idx_is_less = ((idxs == len(array))|(np.fabs(values - array[np.maximum(idxs-1, 0)]) < np.fabs(values - array[np.minimum(idxs, len(array)-1)])))
    idxs[prev_idx_is_less] -= 1

    return array[idxs]

From the PHP manual:

The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). PHP does not support unsigned integers. Integer size can be determined using the constant PHP_INT_SIZE, and maximum value using the constant PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5.

64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit.

It is a unicode char \u003C = <

There are several ways I can think of to do this.

Use a callback:

 function FunctInit(someVarible){
      //init and fill screen
      AndroidCallGetResult();  // Enables Android button.
 }

 function getResult(){ // Called from Android button only after button is enabled
      //return some variables
 }

Use a Timeout (this would probably be my preference):

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      if (inited) {
           //return some variables
      } else {
           setTimeout(getResult, 250);
      }
 }

Wait for the initialization to occur:

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      var a = 1;
      do { a=1; }
      while(!inited);
      //return some variables
 }

Create /res/drawable/button.xml with the following content :

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<!-- you can use any color you want I used here gray color-->
 <solid android:color="#90EE90"/> 
    <corners
     android:bottomRightRadius="3dp"
     android:bottomLeftRadius="3dp"
  android:topLeftRadius="3dp"
  android:topRightRadius="3dp"/>
</shape>

And then you can use the following :

<Button
    android:id="@+id/button_save_prefs"
    android:text="@string/save"
    android:background="@drawable/button"/>

As suggested, you can use some 3rd party library, or do it manually (which is not that much work), but the simplest and the most flexible is to perhaps use the built-in functionality in .NET. For more see:

• System.Drawing.Image.PropertyItems Property

• System.Drawing.Imaging.PropertyItem Class

• How to: Read Image Metadata

I say "it’s the most flexible" because .NET does not try to interpret or coalesce the data in any way. For each EXIF you basically get an array of bytes. This may be good or bad depending on how much control you actually want.

Also, I should point out that the property list does not in fact directly correspond to the EXIF values. EXIF itself is stored in multiple tables with overlapping ID’s, but .NET puts everything in one list and redefines ID’s of some items. But as long as you don’t care about the precise EXIF ID’s, you should be fine with the .NET mapping.

Edit: It's possible to do it without loading the full image following this answer: https://stackoverflow.com/a/552642/2097240

redsquare's solution is the right answer.

But as an IN-THEORY solution you can write a function which is selecting the elements classed by .visibilityCheck (not all visible elements) and check their visibility property value; if true then do something.

Afterward, the function should be performed periodically using the setInterval() function. You can stop the timer using the clearInterval() upon successful call-out.

Here's an example:

function foo() {
    $('.visibilityCheck').each(function() {
        if ($(this).is(':visible')){
            // do something
        }
    });
}

window.setInterval(foo, 100);

You can also perform some performance improvements on it, however, the solution is basically absurd to be used in action. So...

I have solved this issue as follows:

removed from chrome extension and install ext again. It will work ISA

SELECT CONVERT(varchar, @datetime, 103) --for UK Date format 'DD/MM/YYYY'

101 - US - MM/DD/YYYY

108 - Time - HH:MI:SS

112 - Date - YYYYMMDD

121 - ODBC - YYYY-MM-DD HH:MI:SS.FFF

20 - ODBC - YYYY-MM-DD HH:MI:SS

what happened to me is that I have multiple projects in my solution. I meant to debug project 1, however, the project 2 was set as the default starting project. I fixed this by, right click on the project and select "Set as startup project", then running debugging is fine.

To complicate matters further, there is such a thing as thread-local storage, and Unix shared memory.

Thread-local storage allows each thread to have a separate instance of global objects. The only time I've used it was when constructing an emulation environment on linux/windows, for application code that ran in an RTOS. In the RTOS each task was a process with it's own address space, in the emulation environment, each task was a thread (with a shared address space). By using TLS for things like singletons, we were able to have a separate instance for each thread, just like under the 'real' RTOS environment.

Shared memory can (obviously) give you the performance benefits of having multiple processes access the same memory, but at the cost/risk of having to synchronize the processes properly. One way to do that is have one process create a data structure in shared memory, and then send a handle to that structure via traditional inter-process communication (like a named pipe).

In your user settings add:

"C_Cpp.default.includePath":["path1","path2"]

I wouldn't recommend doing this, but you can override the ngClick directive to do what you are looking for. That's not saying, you should.

With the original implementation in mind:

compile: function($element, attr) {
  var fn = $parse(attr[directiveName]);
  return function(scope, element, attr) {
    element.on(lowercase(name), function(event) {
      scope.$apply(function() {
        fn(scope, {$event:event});
      });
    });
  };
}

We can do this to override it:

// Go into your config block and inject $provide.
app.config(function ($provide) {

  // Decorate the ngClick directive.
  $provide.decorator('ngClickDirective', function ($delegate) {

    // Grab the actual directive from the returned $delegate array.
    var directive = $delegate[0];

    // Stow away the original compile function of the ngClick directive.
    var origCompile = directive.compile;

    // Overwrite the original compile function.
    directive.compile = function (el, attrs) {

      // Apply the original compile function. 
      origCompile.apply(this, arguments);

      // Return a new link function with our custom behaviour.
      return function (scope, el, attrs) {

        // Get the name of the passed in function. 
        var fn = attrs.ngClick;

        el.on('click', function (event) {
          scope.$apply(function () {

            // If no property on scope matches the passed in fn, return. 
            if (!scope[fn]) {
              return;
            }

            // Throw an error if we misused the new ngClick directive.
            if (typeof scope[fn] !== 'function') {
              throw new Error('Property ' + fn + ' is not a function on ' + scope);
            }

            // Call the passed in function with the event.
            scope[fn].call(null, event);

          });
        });          
      };
    };    

    return $delegate;
  });
});

Then you'd pass in your functions like this:

<div ng-click="func"></div>

as opposed to:

<div ng-click="func()"></div>

jsBin: http://jsbin.com/piwafeke/3/edit

Like I said, I would not recommend doing this but it's a proof of concept showing you that, yes - you can in fact overwrite/extend/augment the builtin angular behaviour to fit your needs. Without having to dig all that deep into the original implementation.

Do please use it with care, if you were to decide on going down this path (it's a lot of fun though).

I found the solution. The answer is very simple. write the below code in your constructor.

import { Component, OnInit, OnDestroy, Input } from "@angular/core";
// Import this, and write at the top of your .ts file
import { HostListener } from "@angular/core";

@Component({
  selector: "app-login",
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css']
})

export class LoginComponent implements OnInit, OnDestroy {
    // Declare height and width variables
    scrHeight:any;
    scrWidth:any;

    @HostListener('window:resize', ['$event'])
    getScreenSize(event?) {
          this.scrHeight = window.innerHeight;
          this.scrWidth = window.innerWidth;
          console.log(this.scrHeight, this.scrWidth);
    }

    // Constructor
    constructor() {
        this.getScreenSize();
    }


}

====== Working Code (Another) ======

export class Dashboard  {
 mobHeight: any;
 mobWidth: any;
     constructor(private router:Router, private http: Http){
        this.mobHeight = (window.screen.height) + "px";
        this.mobWidth = (window.screen.width) + "px";
          console.log(this.mobHeight);
          console.log(this.mobWidth)
     }
}

No need to go in such deep technicalities, and get yourself blasted. Let me explain it in the most easiest way. We all have studied "Sets" during our school-age in Mathematics. Just consider 3D numpy array as the formation of "sets".

x = np.zeros((2,3,4)) 

Simply Means:

2 Sets, 3 Rows per Set, 4 Columns

Example:

Input

x = np.zeros((2,3,4))

Output

Set # 1 ---- [[[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]], ---- Row 3 
    
Set # 2 ----  [[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]]] ---- Row 3

Explanation: See? we have 2 Sets, 3 Rows per Set, and 4 Columns.

Note: Whenever you see a "Set of numbers" closed in double brackets from both ends. Consider it as a "set". And 3D and 3D+ arrays are always built on these "sets".

function clean($data){
    $data = rawurldecode($data);
    return filter_var($data, FILTER_SANITIZE_SPEC_CHARS);
}

Assuming you want to read from resources directory in FileSystem class.

String file = "dummy.txt";
var path = Paths.get("src/com/company/fs/resources/", file);
System.out.println(path);

System.out.println(Files.readString(path));

Note: Leading . is not needed.

You'll be wanting to use the 'read' command

while read name
do
    echo "$name"
done < names.txt

Note that "$name" is quoted -- if it's not, it will be split using the characters in $IFS as delimiters. This probably won't be noticed if you're just echoing the variable, but if your file contains a list of file names which you want to copy, those will get broken down by $IFS if the variable is unquoted, which is not what you want or expect.

If you want to use Mike Clark's approach (loading into a variable rather than using read), you can do it without the use of cat:

NAMES="$(< scripts/names.txt)" #names from names.txt file
for NAME in $NAMES; do
    echo "$NAME"
done

The problem with this is that it loads the whole file into $NAMES, when you read it back out, you can either get the whole file (if quoted) or the file broken down by $IFS, if not quoted. By default, this will give you individual words, not individual lines. So if the name "Mary Jane" appeared on a line, you would get "Mary" and "Jane" as two separate names. Using read will get around this... although you could also change the value of $IFS

for springboot 2.1.7 working with url seems not to work. change with jdbcUrl instead.

In properties:

security:
      datasource:
        jdbcUrl: jdbc:mysql://ip:3306/security
        username: user
        password: pass

In java:

@ConfigurationProperties(prefix = "security.datasource")
@Bean("dataSource")
@Primary
public DataSource dataSource(){

    return DataSourceBuilder
            .create()
            .build();
}

First, use the bounding boxes as described by Jonathan Holland to find if you may have a collision.

From the (multi-color) sprites, create black and white versions. You probably already have these if your sprites are transparent (i.e. there are places which are inside the bounding box but you can still see the background). These are "masks".

Use Image.getRGB() on the mask to get at the pixels. For each pixel which isn't transparent, set a bit in an integer array (playerArray and enemyArray below). The size of the array is height if width <= 32 pixels, (width+31)/32*height otherwise. The code below is for width <= 32.

If you have a collision of the bounding boxes, do this:

// Find the first line where the two sprites might overlap
int linePlayer, lineEnemy;
if (player.y <= enemy.y) {
    linePlayer = enemy.y - player.y;
    lineEnemy = 0;
} else {
    linePlayer = 0;
    lineEnemy = player.y - enemy.y;
}
int line = Math.max(linePlayer, lineEnemy);

// Get the shift between the two
x = player.x - enemy.x;
int maxLines = Math.max(player.height, enemy.height);
for ( line < maxLines; line ++) {
    // if width > 32, then you need a second loop here
    long playerMask = playerArray[linePlayer];
    long enemyMask = enemyArray[lineEnemy];
    // Reproduce the shift between the two sprites
    if (x < 0) playerMask << (-x);
    else enemyMask << x;
    // If the two masks have common bits, binary AND will return != 0
    if ((playerMask & enemyMask) != 0) {
        // Contact!
    }

}

sudo ldconfig

ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/lib and /usr/lib).

Generally package manager takes care of this while installing the new library, but not always (specially when you install library with cmake).

And if the output of this is empty

$ echo $LD_LIBRARY_PATH

Please set the default path

$ LD_LIBRARY_PATH=/usr/local/lib

Methods suggest something has to happen to return the value, properties suggest that the value is already there. This is a rule of thumb, sometimes you might want a property that does a little work (i.e. Count), but generally it's a useful way to decide.

MSDN has the skinny on this.

Here is the function for to check is String is Integer or not ?

public static boolean isStringInteger(String number ){
    try{
        Integer.parseInt(number);
    }catch(Exception e ){
        return false;
    }
    return true;
}

In order to change the attribute of the class conditionally,

var css_val = $(".handle").css('left');
if(css_val == '336px')
{
  $(".handle").css('left','300px');
}

If id is given as following,

<a id="handle" class="handle" href="#" style="left: 336px;"></a>

Here is an alternative solution:

var css_val = $("#handle").css('left');
if(css_val == '336px')
{
  $("#handle").css('left','300px');
}

Use ==:

pip install django_modeltranslation==0.4.0-beta2

for i in ('apple', 'banana', 'carrot'):
    fruitdict[i] = locals()[i]

do this in you manifest file:

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

git-status porcelain (machine-readable) v2 output looks like this:

$ git status -b --porcelain=v2
# branch.oid d0de00da833720abb1cefe7356493d773140b460
# branch.head the-branch-name
# branch.upstream gitlab/the-branch-name
# branch.ab +2 -2

And to get the branch upstream only:

$ git status -b --porcelain=v2 | grep -m 1 "^# branch.upstream " | cut -d " " -f 3-
gitlab/the-branch-name

If the branch has no upstream, the above command will produce an empty output (or fail with set -o pipefail).

By unpacking timetuple of datetime object, you should get what you want:

from datetime import datetime

n = datetime.now()
t = n.timetuple()
y, m, d, h, min, sec, wd, yd, i = t

    public HttpResponseMessage Get(int id,string numb)
    {

        using (MarketEntities entities = new MarketEntities())
        {
          var ent=  entities.Api_For_Test.FirstOrDefault(e => e.ID == id && e.IDNO.ToString()== numb);
            if (ent != null)
            {
                return Request.CreateResponse(HttpStatusCode.OK, ent);
            }
            else
            {
                return Request.CreateErrorResponse(HttpStatusCode.NotFound, "Applicant with ID " + id.ToString() + " not found in the system");
            }
        }
    }

Mongoose is built untop of mongodb driver, the mongodb driver is more low level. Mongoose provides that easy abstraction to easily define a schema and query. But on the perfomance side Mongdb Driver is best.

You can use ContainsKey:

if (dict.ContainsKey(key)) { ... }

or TryGetValue:

dict.TryGetValue(key, out value);

Update: according to a comment the actual class here is not an IDictionary but a PhysicalAddressDictionary, so the methods are Contains and TryGetValue but they work in the same way.

Example usage:

PhysicalAddressEntry entry;
PhysicalAddressKey key = c.PhysicalAddresses[PhysicalAddressKey.Home].Street;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    row["HomeStreet"] = entry;
}

Update 2: here is the working code (compiled by question asker)

PhysicalAddressEntry entry;
PhysicalAddressKey key = PhysicalAddressKey.Home;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    if (entry.Street != null)
    {
        row["HomeStreet"] = entry.Street.ToString();
    }
}

...with the inner conditional repeated as necessary for each key required. The TryGetValue is only done once per PhysicalAddressKey (Home, Work, etc).

You need nunique:

df = df.groupby('domain')['ID'].nunique()

print (df)
domain
'facebook.com'    1
'google.com'      1
'twitter.com'     2
'vk.com'          3
Name: ID, dtype: int64

If you need to strip ' characters:

df = df.ID.groupby([df.domain.str.strip("'")]).nunique()
print (df)
domain
facebook.com    1
google.com      1
twitter.com     2
vk.com          3
Name: ID, dtype: int64

Or as Jon Clements commented:

df.groupby(df.domain.str.strip("'"))['ID'].nunique()

You can retain the column name like this:

df = df.groupby(by='domain', as_index=False).agg({'ID': pd.Series.nunique})
print(df)
    domain  ID
0       fb   1
1      ggl   1
2  twitter   2
3       vk   3

The difference is that nunique() returns a Series and agg() returns a DataFrame.

I don't use named parameters for all queries. For example it is unusual to use named parameters in JpaRepository.

To workaround I use JPQL CONCAT function (this code emulate start with):

@Repository
public interface BranchRepository extends JpaRepository<Branch, String> {
    private static final String QUERY = "select b from Branch b"
       + " left join b.filial f"
       + " where f.id = ?1 and b.id like CONCAT(?2, '%')";
    @Query(QUERY)
    List<Branch> findByFilialAndBranchLike(String filialId, String branchCode);
}

I found this technique in excellent docs: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/jpa_overview_query.html

Xcode 8 beta 2 • Swift 3

let myString = "Hello World"
let myRange = myString.startIndex..<myString.index(myString.startIndex, offsetBy: 5)
let mySubString = myString.substring(with: myRange)   // Hello

Xcode 7 • Swift 2.0

let myString = "Hello World"
let myRange = Range<String.Index>(start: myString.startIndex, end: myString.startIndex.advancedBy(5))

let mySubString = myString.substringWithRange(myRange)   // Hello

or simply

let myString = "Hello World"
let myRange = myString.startIndex..<myString.startIndex.advancedBy(5)
let mySubString = myString.substringWithRange(myRange)   // Hello

Your problem is that you're not closing your HEREDOC correctly. The line containing END; must not contain any whitespace afterwards.

When you want start a new activity and finish the current activity you can do this:

API 11 or greater

Intent intent = new Intent(OldActivity.this, NewActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);

API 10 or lower

Intent intent = new Intent(OldActivity.this, NewActivity.class);
intent.setFlags(IntentCompat.FLAG_ACTIVITY_NEW_TASK | IntentCompat.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);

I hope this can help somebody =)

There are several ways to do this:

InStr

You can use the InStr build-in function to test if a String contains a substring. InStr will either return the index of the first match, or 0. So you can test if a String begins with a substring by doing the following:

If InStr(1, "Hello World", "Hello W") = 1 Then
    MsgBox "Yep, this string begins with Hello W!"
End If

If InStr returns 1, then the String ("Hello World"), begins with the substring ("Hello W").

Like

You can also use the like comparison operator along with some basic pattern matching:

If "Hello World" Like "Hello W*" Then
    MsgBox "Yep, this string begins with Hello W!"
End If

In this, we use an asterisk (*) to test if the String begins with our substring.

For anyone running Windows 10 1607 and looking for .net 4.7. Disregard all of the above.

It's not in the Registry, C:\Windows\Microsoft.NET folder or the Installed Programs list or the WMIC display of that same list.

Look for "installed updates" KB3186568.

Add cast RemoteWebDriver to driver initialize and you will have the .setLogLevel method:

import java.util.logging.Level;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;

public class PrintLogTest {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "/Users/.../chromedriver");
        WebDriver driver = new ChromeDriver();

        //here
        ((RemoteWebDriver) driver).setLogLevel(Level.INFO);

        driver.get("https://google.com/");
        driver.findElement(By.name("q")).sendKeys("automation test");
        driver.quit();
    }
}

Example output:

Jun 15, 2020 4:27:04 PM org.openqa.selenium.remote.RemoteWebDriver log

At least I've tried it on ChromeDriver() and FirefoxDriver() and it working fine.

I wrote a simpler loop that works too (note that all my values are unique):

HashMap<Character, String> myHashMap = new HashMap<Character, String>();
HashMap<String, Character> reversedHashMap = new HashMap<String, Character>();

for (char i : myHashMap.keySet()) {
    reversedHashMap.put(myHashMap.get(i), i);
}

I'm a bit late to the party here i know but,

You could directly access the calls object, which can give you the variables for each call

expect(spy.calls.argsFor(0)[0].value).toBe(expectedValue)

A delarative way to do that (In fact, a minor tweek to @Compito's original answer):

1. Set spring.profiles.active=test in test/resources/application-default.properties.
2. Add test/resources/application-test.properties for tests and override only the properties you need.

It seems from your question that you would like to simply increment the year of your given date rather than worry about leap year implications. You can use the date class to do this by accessing its member year.

from datetime import date
startDate = date(2012, 12, 21)

# reconstruct date fully
endDate = date(startDate.year + 1, startDate.month, startDate.day)
# replace year only
endDate = startDate.replace(startDate.year + 1)

If you're having problems creating one given your format, let us know.

A new plugin has appeared to fix shortcomings of mvn dependency:go-offline:

https://github.com/qaware/go-offline-maven-plugin

Add it in your pom, then run mvn -T1C de.qaware.maven:go-offline-maven-plugin:resolve-dependencies. Once you've setup all dynamic dependencies, maven won't try to download anything again (until you update versions).

I am Using Design Support Library. And just by using custom theme I achived transparent Status Bar when Opened Navigation Drawer.

<style name="NavigationStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primaryColor</item>
    <item name="colorPrimaryDark">@color/primaryColorDark</item>

    <!-- To Make Navigation Drawer Fill Status Bar and become Transparent Too -->
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>

</style>

Finally add theme in Manifest File

<activity
  ........
  ........
 android:theme="@style/NavigationStyle"> 
</activity>

Do not forget to use the property, android:fitsSystemWindows="true" in "DrawerLayout"

I think if you overwrite a method and want to all the super-class version of it (like, say for equals), then you virtually always want to call the direct superclass version first, which one will call its superclass version in turn if it wants.

I think it only makes rarely sense (if at all. i can't think of a case where it does) to call some arbitrary superclass' version of a method. I don't know if that is possible at all in Java. It can be done in C++:

this->ReallyTheBase::foo();

I used yet another trick to format date with 6-digit precision (microseconds):

System.out.println(
    new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.").format(microseconds/1000)
    +String.format("%06d", microseconds%1000000));

This technique can be extended further, to nanoseconds and up.

This is the Kotlin way:

In fragment_map.xml you should have:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

In your MapFragment.kt you should have:

    private fun setupMap() {
        (childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?)!!.getMapAsync(this)
    }

Call setupMap() in onCreateView.

Thanks to dimo414's answer to a similar question, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:

example output

$ ./test.sh

The text from the example function is:
  Welcome dev: Would you "like" to know how many 'files' there are in /tmp?

  There are "      38" files in /tmp, according to the "wc" command

test.sh

#!/bin/bash

function text1()
{
  COUNT=$(\ls /tmp | wc -l)
cat <<EOF

  $1 Would you "like" to know how many 'files' there are in /tmp?

  There are "$COUNT" files in /tmp, according to the "wc" command

EOF
}

function main()
{
  OUT=$(text1 "Welcome dev:")
  echo "The text from the example function is: $OUT"
}

main

Do simply like below....

HashMap<String,Object> yourHash = new HashMap<String,Object>();
yourHash.put(yourKey+"message","message");
yourHash.put(yourKey+"timestamp",timestamp);
yourHash.put(yourKey+"count ",count);
yourHash.put(yourKey+"version ",version);

typecast the value while getting back. For ex:

    int count = Integer.parseInt(yourHash.get(yourKey+"count"));
//or
int count = Integer.valueOf(yourHash.get(yourKey+"count"));
//or
int count = (Integer)yourHash.get(yourKey+"count"); //or (int)

You need to look at the Backgroundworker example:
http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.aspx Especially how it interacts with the UI layer. Based on your posting, this seems to answer your issues.

Don't ever use the setInterval or setTimeout functions for time measuring! They are unreliable, and it is very likely that the JS execution scheduling during a documents parsing and displaying is delayed.

Instead, use the Date object to create a timestamp when you page began loading, and calculate the difference to the time when the page has been fully loaded:

<doctype html>
<html>
    <head>
        <script type="text/javascript">
            var timerStart = Date.now();
        </script>
        <!-- do all the stuff you need to do -->
    </head>
    <body>
        <!-- put everything you need in here -->

        <script type="text/javascript">
             $(document).ready(function() {
                 console.log("Time until DOMready: ", Date.now()-timerStart);
             });
             $(window).load(function() {
                 console.log("Time until everything loaded: ", Date.now()-timerStart);
             });
        </script>
    </body>
</html>

If you use docker in your dev you can do this in another shell: docker attach running_node_app_container_name

That will show you STDOUT and STDERR.

select price from mobile_sales_details order by price desc limit 5

Note: i have mobile_sales_details table

syntax

select column_name from table_name order by column_name desc limit size.  

if you need top low price just remove the keyword desc from order by

If you can use repeated letters, you can use the * operator:

>>> 'a'*5

'aaaaa'

The lambda:

() -> { System.out.println("Do nothing!"); };

actually represents an implementation for an interface like:

public interface Something {
    void action();
}

which is completely different than the one you've defined. That's why you get an error.

Since you can't extend your @FunctionalInterface, nor introduce a brand new one, then I think you don't have much options. You can use the Optional<T> interfaces to denote that some of the values (return type or method parameter) is missing, though. However, this won't make the lambda body simpler.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

You can use reflect.DeepEqual, or you can implement your own function (which performance wise would be better than using reflection):

http://play.golang.org/p/CPdfsYGNy_

m1 := map[string]int{   
    "a":1,
    "b":2,
}
m2 := map[string]int{   
    "a":1,
    "b":2,
}
fmt.Println(reflect.DeepEqual(m1, m2))

Even though methai's answer is correct if you manually run the query, a problem occurs when 2 concurrent transaction/connections actually execute this query at runtime in production (for instance).

Just tried manually in MySQL workbench with 2 connections opened simultaneously:

CREATE TABLE translation (
  id BIGINT PRIMARY KEY AUTO_INCREMENT
);
# Suppose we have already 20 entries, we execute 2 new inserts:

Transaction 1:

21 = SELECT `AUTO_INCREMENT` FROM INFORMATION_SCHEMA.TABLES
     WHERE TABLE_SCHEMA = 'DatabaseName' AND TABLE_NAME = 'translation';

insert into translation (id) values (21);

Transaction 2:

21 = SELECT `AUTO_INCREMENT` FROM INFORMATION_SCHEMA.TABLES
     WHERE TABLE_SCHEMA = 'DatabaseName' AND TABLE_NAME = 'translation';

insert into translation (id) values (21);

# commit transaction 1;
# commit transaction 2;

Insert of transaction 1 is ok: Insert of transaction 2 goes in error: Error Code: 1062. Duplicate entry '21' for key 'PRIMARY'.

A good solution would be jvdub's answer because per transaction/connection the 2 inserts will be:

Transaction 1:

insert into translation (id) values (null);
21 = SELECT LAST_INSERT_ID();

Transaction 2:

insert into translation (id) values (null);
22 = SELECT LAST_INSERT_ID();

# commit transaction 1;
# commit transaction 2;

But we have to execute the last_insert_id() just after the insert! And we can reuse that id to be inserted in others tables where a foreign key is expected!

Also, we cannot execute the 2 queries as following:

insert into translation (id) values ((SELECT AUTO_INCREMENT FROM
    information_schema.TABLES WHERE TABLE_SCHEMA=DATABASE()
    AND TABLE_NAME='translation'));

because we actually are interested to grab/reuse that ID in other table or to return!

No method can be invoked on a object which is assigned a NULL value. It will give a nullPointerException. Hence, s2.length() is giving an exception.

You can pass it as Action<string> - which means it is a method with a single parameter of type string that doesn't return anything (void) :

public void DoRequest(string request, Action<string> callback)
{
    // do stuff....
    callback("asdf");
}

Varchar Date Convert to Date and Change the Format

Nov 12 2016 12:00 , 21/12/2016, 21-12-2016 this Query Works for above to change to this Format dd/MM/yyyy SELECT [Member_ID],[Name] , Convert(varchar(50),Convert(date,[DOB],103),103) as DOB ,[NICNO],[Relation] FROM [dbo].[tbl_FamilMember]

public void updateLaserDataByHumanId(String replacement, String humanId) {
    List<LaserData> laserDataByHumanId = laserDataRepository.findByHumanId(humanId);
    laserDataByHumanId.stream()
            .map(en -> en.setHumanId(replacement))
            .collect(Collectors.toList())
            .forEach(en -> laserDataRepository.save(en));
}

This should be an answer

str2.equals( str )

If you want to ignore case

str2.equalsIgnoreCase( str )

They are the same.

One thing to be careful of, is if you are using this against a DATETIME, the match for the end date will be the beginning of the day:

<= 20/10/2009

is not the same as:

<= 20/10/2009 23:59:59

(it would match against <= 20/10/2009 00:00:00.000)

I recently migrated my MongoDB to DynamoDB, and wrote 3 blogs to share some experience and data about performance, cost.

Migrate from MongoDB to AWS DynamoDB + SimpleDB

7 Reasons You Should Use MongoDB over DynamoDB

3 Reasons You Should Use DynamoDB over MongoDB

Generator Function, Generator Object, Generator:

A Generator function is just like a regular function in Python but it contains one or more yield statements. Generator functions is a great tool to create Iterator objects as easy as possible. The Iterator object returend by generator function is also called Generator object or Generator.

In this example I have created a Generator function which returns a Generator object <generator object fib at 0x01342480>. Just like other iterators, Generator objects can be used in a for loop or with the built-in function next() which returns the next value from generator.

def fib(max):
    a, b = 0, 1
    for i in range(max):
        yield a
        a, b = b, a + b
print(fib(10))             #<generator object fib at 0x01342480>

for i in fib(10):
    print(i)               # 0 1 1 2 3 5 8 13 21 34


print(next(myfib))         #0
print(next(myfib))         #1
print(next(myfib))         #1
print(next(myfib))         #2

So a generator function is the easiest way to create an Iterator object.

Iterator:

Every generator object is an iterator but not vice versa. A custom iterator object can be created if its class implements __iter__ and __next__ method (also called iterator protocol).

However, it is much easier to use generators function to create iterators because they simplify their creation, but a custom Iterator gives you more freedom and you can also implement other methods according to your requirements as shown in the below example.

class Fib:
    def __init__(self,max):
        self.current=0
        self.next=1
        self.max=max
        self.count=0

    def __iter__(self):
        return self

    def __next__(self):
        if self.count>self.max:
            raise StopIteration
        else:
            self.current,self.next=self.next,(self.current+self.next)
            self.count+=1
            return self.next-self.current

    def __str__(self):
        return "Generator object"

itobj=Fib(4)
print(itobj)               #Generator object

for i in Fib(4):  
    print(i)               #0 1 1 2

print(next(itobj))         #0
print(next(itobj))         #1
print(next(itobj))         #1

Here is example of pseudo-random generator when neither $RANDOM nor /dev/urandom is available

echo $(date +%S) | grep -o .$ | sed s/0/10/

I had a similar problem when I deployed my Flask app in the IIS. Apparently, IIS does not accept route that include an underline ("_"). When I removed the underline, problem was resolved.

Use doubleval(). But be very careful about using decimals in financial transactions, and validate that user input very carefully.

If you are looking for something in production winston is probably the best choice.

If you just want to do dev stuff quickly, output directly to a file (I think this works only for *nix systems):

nohup node simple-server.js > output.log &

Shortest

I improve Sai Sunder answer because OP uses ID which allows to avoid getElementById:

elementId.remove();

box2.remove();          // remove BOX 2_x000D_
_x000D_
this["box-3"].remove(); // remove BOX 3 (for Id with 'minus' character)

<div id="box1">My BOX 1</div>_x000D_
<div id="box2">My BOX 2</div>_x000D_
<div id="box-3">My BOX 3</div>_x000D_
<div id="box4">My BOX 4</div>

Consider the following servlet conf:

   <servlet>
        <servlet-name>NewServlet</servlet-name>
        <servlet-class>NewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>NewServlet</servlet-name>
        <url-pattern>/NewServlet/*</url-pattern>
    </servlet-mapping>

Now, when I hit the URL http://localhost:8084/JSPTemp1/NewServlet/jhi, it will invoke NewServlet as it is mapped with the pattern described above.

Here:

getRequestURI() =  /JSPTemp1/NewServlet/jhi
getPathInfo() = /jhi

We have those ones:

• getPathInfo()

  returns
  a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information

• getRequestURI()

  returns
  a String containing the part of the URL from the protocol name up to the query string

Just this

super.onBackPressed();

The problem is with the method:

private void Flow()
{
    X = x;
    Y = y;
}

Your class is named Flow so this method can't also be named Flow. You will have to change the name of the Flow method to something else to make this code compile.

Or did you mean to create a private constructor to initialize your class? If that's the case, you will have to remove the void keyword to let the compiler know that your declaring a constructor.

I'm using a old version of Hibernate (3.3.0) with a newest version of OpenEJB (4.6.0). My solution was:

EntityManagerImpl entityManager = (EntityManagerImpl)em.getDelegate();
Session session = entityManager.getSession();
Connection connection = session.connection();
Statement statement = null;
try {
    statement = connection.createStatement();
    statement.execute(sql);
    connection.commit();
} catch (SQLException e) {
    throw new RuntimeException(e);
}

I had an error after that:

Commit can not be set while enrolled in a transaction

Because this code above was inside a EJB Controller (you can't commit inside a transaction). I annotated the method with @TransactionAttribute(value = TransactionAttributeType.NOT_SUPPORTED) and the problem was gone.

After looking around on Google for a long time, trying out several solutions, both CSS, JavaScript and JQuery, i found that most of them were using an Image as the button. Some of them were hard to use, but i did manage to piece together something that ended out working out for me.

The important parts for me was:

• The Browse button had to be a Button (not an image).
• The button had to have a hover effect (to make it look nice).
• The Width of both the Text and the button had to be easy to adjust.
• The solution had to work in IE8, FF, Chrome and Safari.

This is the solution i came up with. And hope it can be of use to others as well.

Change the width of .file_input_textbox to change the width of the textbox.

Change the width of both .file_input_div, .file_input_button and .file_input_button_hover to change the width of the button. You might need to tweak a bit on the positions also. I never figured out why...

To test this solution, make a new html file and paste the content into it.

<html>
<head>

<style type="text/css">

.file_input_textbox {height:25px;width:200px;float:left; }
.file_input_div     {position: relative;width:80px;height:26px;overflow: hidden; }
.file_input_button  {width: 80px;position:absolute;top:0px;
                     border:1px solid #F0F0EE;padding:2px 8px 2px 8px; font-weight:bold; height:25px; margin:0px; margin-right:5px; }
.file_input_button_hover{width:80px;position:absolute;top:0px;
                     border:1px solid #0A246A; background-color:#B2BBD0;padding:2px 8px 2px 8px; height:25px; margin:0px; font-weight:bold; margin-right:5px; }
.file_input_hidden  {font-size:45px;position:absolute;right:0px;top:0px;cursor:pointer;
                     opacity:0;filter:alpha(opacity=0);-ms-filter:"alpha(opacity=0)";-khtml-opacity:0;-moz-opacity:0; }
</style>
</head>
<body>
    <input type="text" id="fileName" class="file_input_textbox" readonly="readonly">
 <div class="file_input_div">
  <input id="fileInputButton" type="button" value="Browse" class="file_input_button" />
  <input type="file" class="file_input_hidden" 
      onchange="javascript: document.getElementById('fileName').value = this.value" 
      onmouseover="document.getElementById('fileInputButton').className='file_input_button_hover';"

Just for the kicks.

Since I wasnt able to create linked server and since just connecting to production server was not enough to use INSERT INTO i did the following:

• created a backup of production server database
• restored the database on my test server
• executed the insert into statements

Its a backdoor solution, but since i had problems it worked for me.

Since i have created empty tables using SCRIPT TABLE AS / CREATE in order to transfer all the keys and indexes I couldnt use SELECT INTO. SELECT INTO only works if the tables do not exist on the destination location but it does not copy keys and indexes, so you have to do that manualy. The downside of using INSERT INTO statement is that you have to manualy provide with all the column names, plus it might give you some problems if some foreign key constraints fail.

Thanks to all anwsers, there are some great solutions but i have decided to accept marc_s anwser.

SQL Server(2012) provides another way to generate script for the SQL Server databases with its objects and data. This script can be used to copy the tables’ schema and data from the source database to the destination one in our case.

1. Using the SQL Server Management Studio, right-click on the source database from the object explorer, then from Tasks choose Generate Scripts.
2. In the Choose objects window, choose Select Specific Database Objects to specify the tables that you will generate script for, then choose the tables by ticking beside each one of it. Click Next.
3. In the Set Scripting Options window, specify the path where you will save the generated script file, and click Advanced.
4. From the appeared Advanced Scripting Options window, specify Schema and Data as Types of Data to Script. You can decide from here if you want to script the indexes and keys in your tables. Click OK. Getting back to the Advanced Scripting Options window, click Next.
5. Review the Summary window and click Next.
6. You can monitor the progress from the Save or Publish Scripts window. If there is no error click Finish and you will find the script file in the specified path.

SQL Scripting method is useful to generate one single script for the tables’ schema and data, including the indexes and keys. But again this method doesn’t generate the tables’ creation script in the correct order if there are relations between the tables.

For Notepad++ 5.9

1. Press Ctrl+H
2. Select Search mode Extended(\n, \r, \t, \o, \x...)
3. Enter Find what: \r\n
4. Enter Replace with: ,
5. Replace_All should get the required result.

Doesn't the error exactly tell you what's wrong? You're calling requestWindowFeature and setFeatureInt after you're calling setContentView.

By the way, why are you calling setContentView twice?

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

change to:

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

tl;dr

LocalDate           // Represent a date-only, without time-of-day and without time zone.
.now()              // Better to pass a `ZoneId` optional argument to `now` as shown below than rely implicitly on the JVM’s current default time zone.
.getDayOfMonth()    // Interrogate for the day of the month (1-31). 

java.time

The modern approach is the LocalDate class to represent a date-only value.

A time zone is crucial in determine the current date. For any given moment, the date varies around the globe by zone.

ZoneId z = ZoneId.of( "America/Montreal" );
LocalDate ld = LocalDate.now( z ) ;
int dayOfMonth = ld.getDayOfMonth();

You can also get the day-of-week.

DayOfWeek dow = ld.getDayOfWeek();

About java.time

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

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

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

Using a JDBC driver compliant with JDBC 4.2 or later, you may exchange java.time objects directly with your database. No need for strings nor java.sql.* classes.

Where to obtain the java.time classes?

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

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

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode, and advises migration to the java.time classes. This section left intact for history.

Using the Joda-Time 2.5 library rather than the notoriously troublesome java.util.Date and .Calendar classes.

Time zone is crucial to determining a date. Better to specify the zone rather than rely implicitly on the JVM’s current default time zone being assigned.

DateTimeZone zone = DateTimeZone.forID( "America/Montreal" );
DateTime now = DateTime.now( zone ).withTimeAtStartOfDay();
int dayOfMonth = now.getDayOfMonth();

Or use similar code with the LocalDate class that has no time-of-day portion.

There's also str_pad

<?php
$input = "Alien";
echo str_pad($input, 10);                      // produces "Alien     "
echo str_pad($input, 10, "-=", STR_PAD_LEFT);  // produces "-=-=-Alien"
echo str_pad($input, 10, "_", STR_PAD_BOTH);   // produces "__Alien___"
echo str_pad($input, 6 , "___");               // produces "Alien_"
?>

Here's a 3D array case

class Array3D
   def initialize(d1,d2,d3)
    @data = Array.new(d1) { Array.new(d2) { Array.new(d3) } }
   end

  def [](x, y, z)
    @data[x][y][z]
  end

  def []=(x, y, z, value)
    @data[x][y][z] = value
  end
end

You can access subsections of each array just like any other Ruby array. @data[0..2][3..5][8..10] = 0 etc

Unlike other methods presented here, this bit of code will not cause the browser to display a warning asking the user if he wants to leave; instead, it exploits the evented nature of the DOM to redirect back to the current page (and thus cancel navigation) before the browser has a chance to unload it from memory.

Since it works by short-circuiting navigation directly, it cannot be used to prevent the page from being closed; however, it can be used to disable frame-busting.

(function () {
    var location = window.document.location;

    var preventNavigation = function () {
        var originalHashValue = location.hash;

        window.setTimeout(function () {
            location.hash = 'preventNavigation' + ~~ (9999 * Math.random());
            location.hash = originalHashValue;
        }, 0);
    };

    window.addEventListener('beforeunload', preventNavigation, false);
    window.addEventListener('unload', preventNavigation, false);
})();

Disclaimer: You should never do this. If a page has frame-busting code on it, please respect the wishes of the author.

Android Studio 2.2.3 Linux Mint 18.1

Inside your 'project view' open Gradle Scripts -> build.gradle(Module:app) and put your mouse pointer inside the word dependencies.

Click on the light bulb and click "add library dependency" and for me all the libraries I wanted were listed there.

example libraries that came up for me: compile 'com.android.support:gridlayout-v7:25.1.0' compile 'com.android.support:support-v13:25.1.0'

I am now looking to add android support by default in Gradles default configuration.

You could try to create your own color palette using the RColorBrewer package

my_palette <- colorRampPalette(c("green", "black", "red"))(n = 1000)

and see how this looks like. But I assume in your case only scaling would help if you really want to keep the black in "the middle". You can simply use my_palette instead of the redgreen()

I recommend that you check out the RColorBrewer package, they have pretty nice in-built palettes, and see interactive website for colorbrewer.

I had a case where I would take photos of clients online and would need to update the div if a photo is changed. Browser was still showing the old photo. So I used the hack of calling a random GET variable, which would be unique every time. Here it is if it could help anybody

<img src="/photos/userid_73.jpg?random=<?php echo rand() ?>" ...

EDIT As pointed out by others, following is much more efficient solution since it will reload images only when they are changed, identifying this change by the file size:

<img src="/photos/userid_73.jpg?modified=<? filemtime("/photos/userid_73.jpg")?>"

This code works very fast. It comes from here

You could also consider using getting the indexes of last elements in each specified dimensions using this as following;

int x = ary.GetUpperBound(0);
int y = ary.GetUpperBound(1);

Keep in mind that this gets the value of index as 0-based.

At a minimum you are going to need to know the column delimiter.

This code is ill-formed:

int&const icr=i;

Reference: C++17 [dcl.ref]/1:

Cv-qualified references are ill-formed except when the cv-qualifiers are introduced through the use of a typedef-name or decltype-specifier, in which case the cv-qualifiers are ignored.

This rule has been present in all standardized versions of C++. Because the code is ill-formed:

• you should not use it, and
• there is no associated behaviour.

The compiler should reject the program; and if it doesn't, the executable's behaviour is completely undefined.

NB: Not sure how none of the other answers mentioned this yet... nobody's got access to a compiler?

SELECT user_id 
FROM user_logs 
WHERE login_date BETWEEN '2014-02-01' AND '2014-03-01'

Between keyword works exceptionally for a date. it assumes the time is at 00:00:00 (i.e. midnight) for dates.

You can use subprocess.Popen. There's a few ways to do it:

import subprocess
cmd = ['/run/myscript', '--arg', 'value']
p = subprocess.Popen(cmd, stdout=subprocess.PIPE)
for line in p.stdout:
    print line
p.wait()
print p.returncode

Or, if you don't care what the external program actually does:

cmd = ['/run/myscript', '--arg', 'value']
subprocess.Popen(cmd).wait()

Chrome is a Chromium-based browser and Chromium-based browsers only allow maximum 6 open socket connections at a time, when the 7th connection starts up it will just sit idle and wait for one of the 6 which are running to stop and then it will start running. Hence the error code ‘waiting for available sockets’, the 7th one will wait for one of those 6 sockets to become available and then it will start running.

You can either

• 1. Clear browser cache & cookies (https://geekdroids.com/waiting-for-available-socket/#1_Clear_browser_cache_cookies)
• 2. Flush socket pools (https://geekdroids.com/waiting-for-available-socket/#2_Flush_socket_pools)
• 3. Flush DNS (https://geekdroids.com/waiting-for-available-socket/#3_Flush_DNS)

}

export default function exampleUse() {
  return (

change in Recycler view match_parent to wrap_content:

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycleView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

Also change in item layout xml

Make parent layout height match_parent to wrap_content

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

Just use another container to wrap last two divs. Don't forget to use CSS prefixes.

You can do something like this :

<asp:Button ID="Button1" runat="server" Text="Button"
    onclick="Button1_Click" OnClientClick="document.forms[0].target = '_blank';" />

You can write JavaScript code in your file .

Put following code in your client side file:

<script>

    window.onload = function(){
         window.open(url, "_blank"); // will open new tab on window.onload
    }
</script>

using jQuery.ready

<script>
  $(document).ready(function(){
      window.open(url, "_blank"); // will open new tab on document ready
  });
</script>

A lot of answers only explain how to do the search.

To view the results look for a search tab (normally docked at the bottom of the screen):

All the three syntax work very well.

Another way is to first write

path = r'C:\user\...................' (whatever is the path for you)

and then passing it to os.chdir(path)

Very similar to previous responses, but the is from the current directory, looks at any file and only for ones that are 4 days old. This is what I needed for my research and the above answers were all very helpful. Thanks.

Get-ChildItem -Path . -Recurse| ? {$_.LastWriteTime -gt (Get-Date).AddDays(-4)}

To build off what Martjin was saying. I'd use string interpolation/formatting.

In Python 2.x which seems to be what you're using due to the lack of parenthesis around the print function you do:

print 'Value is "%d"' % value

In Python 3.x you'd use the format method instead, so you're code would look like this.

message = 'Value is "{}"'
print(message.format(value))

As above told, if you want no one can change the functionality of the method then you can declare it as final.

Example: Application server file path for download/upload, splitting string based on offset, such methods you can declare it Final so that these method functions will not be altered. And if you want such final methods in a separate class, then define that class as Final class. So Final class will have all final methods, where as Final method can be declared and defined in non-final class.

Simply run the alter table query using 'KEY' instead of 'FOREIGN KEY' in the drop statement. I hope it will help to solve the issue, and will drop the foreign key constraint and you can change the table columns and drop the table.

ALTER TABLE slide_image_sub DROP  KEY  FK_slide_image_sub;

here in DROP KEY instead of DROP FOREIGN KEY,

hope it will help.

Thanks

You can create an empty file whether it exists or not ...

new FileOutputStream("score.txt", false).close();

if you want to leave the file if it exists ...

new FileOutputStream("score.txt", true).close();

You will only get a FileNotFoundException if you try to create the file in a directory which doesn't exist.

The default vector constructor will create an empty vector. As such, you should be able to write:

struct user r = { string(), vector<unsigned char>() };

Note, I've also used the default string constructor instead of "".

You might want to consider making user a class and adding a default constructor that does this for you:

class User {
  User() {}
  string username;
  vector<unsigned char> password;
};

Then just writing:

User r;

Will result in a correctly initialized user.

While many people will suggest more or less strict Hungarian notation variants (scary!), for naming suggestions I'd suggest you take a look at Google C++ Coding Guidelines. This may well be not the most popular naming conventions, but at least it's fairly complete. Apart from sound naming conventions, there's some useful guidelines there, however much of it should be taken with a grain of salt (exception ban for example, and the tendency to keep away from modern C++ coding style).

Although personally I like the extreme low-tech convention style of STL and Boost ;).

Heads up,

JAVASCRIPT

<script>
   function readMtlAtClient(){

       mtlFileContent = '';

       var mtlFile = document.getElementById('mtlFileInput').files[0];
       var readerMTL = new FileReader();

       // Closure to capture the file information.
       readerMTL.onload = (function(reader) {
           return function() {
               mtlFileContent = reader.result;
               mtlFileContent = mtlFileContent.replace('data:;base64,', '');
               mtlFileContent = window.atob(mtlFileContent);

           };
       })(readerMTL);

       readerMTL.readAsDataURL(mtlFile);
   }
</script>

HTML

    <input class="FullWidth" type="file" name="mtlFileInput" value="" id="mtlFileInput" 
onchange="readMtlAtClient()" accept=".mtl"/>

Then mtlFileContent has your text as a decoded string !

First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.

if you need pass argument to update method you can do it like this

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }

and get these arguments inside update method

update(e, space, txt){
   console.log(e.target, space, txt);
}

Example

event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset

<button 
  data-space="home" 
  className="home" 
  data-txt="Home" 
  onClick={ this.props.onClick } 
/> 
  Button
</button>

onClick(e) {
   console.log(e.target.dataset.txt, e.target.dataset.space);
}

Example

Use a CASE statement.

Example B in this page should be close to what you're trying to do:
http://msdn.microsoft.com/en-us/library/ms181765.aspx

Here's the code from the page:

USE AdventureWorks;
GO
SELECT   ProductNumber, Name, 'Price Range' = 
      CASE 
         WHEN ListPrice =  0 THEN 'Mfg item - not for resale'
         WHEN ListPrice < 50 THEN 'Under $50'
         WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
         WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
         ELSE 'Over $1000'
      END
FROM Production.Product
ORDER BY ProductNumber ;
GO

There is fast and easy way to do this: In method:

private void OnItemSelected(object sender, SelectedItemChangedEventArgs e)
{
    //TODO
    ((ListView)sender).SelectedItem = null;
}

Hope it'll help ;)

try using a text editing controller. at the begining,

    final myController = TextEditingController();
     @override
  void dispose() {
    // Clean up the controller when the widget is disposed.
    myController.dispose();
    super.dispose();
  }

and in the on press event,

onPressed: () {
            commentController.clear();}

this will dismiss the keybord.

Using a js file you can capture the following, that can be used in the codebehind as well:

<script type="text/javascript">
    alert('Server: ' + window.location.hostname);
    alert('Full path: ' + window.location.href);
    alert('Virtual path: ' + window.location.pathname);
    alert('HTTP path: ' + 
        window.location.href.replace(window.location.pathname, ''));    
</script>

UPDATED

For python 3, you should use items() instead of iteritems()

PYTHON 2

for attr, value in k.__dict__.iteritems():
        print attr, value

PYTHON 3

for attr, value in k.__dict__.items():
        print(attr, value)

This will print

'names', [a list with names]
'tweet', [a list with tweet]

Installing proxyconf will solve this, but behind a proxy you can't install a plugin simply using the command vagrant plugin install, Bundler will raise an error.

set your proxy in your environment if you're using a unix like system

export http_proxy=http://user:password@host:port

or get a more detailed answer here: How to use bundler behind a proxy?

Article on Programming.Guide: Switch on enum

enum MyEnum { CONST_ONE, CONST_TWO }

class Test {
        public static void main(String[] args) {
            MyEnum e = MyEnum.CONST_ONE;

            switch (e) {
                case CONST_ONE: System.out.println(1); break;
                case CONST_TWO: System.out.println(2); break;
            }
        }
    }

Switches for strings are implemented in Java 7.

You started with a one-dimensional list of numbers. Once you used numpy.newaxis, you turned it into a two-dimensional matrix, consisting of four rows of one column each.

You could then use that matrix for matrix multiplication, or involve it in the construction of a larger 4 x n matrix.

I can recommend add small extension to String or Array that looks like

extension Collection {
    public var isNotEmpty: Bool {
        return !self.isEmpty
    }
}

With it you can write code that is easier to read. Compare this two lines

if !someObject.someParam.someSubParam.someString.isEmpty {}

and

if someObject.someParam.someSubParam.someString.isNotEmpty {}

It is easy to miss ! sign in the beginning of fist line.

If you downloaded bootstrap, go to bootstrap-4.4.1-dist/css/bootstrap.min.css

1. find the .navbar-light .navbar-toggler-icon or the .navbar-dark .navbar-toggler-icon selector

2. select the background-image attribute and its value. The snippet looks like this:

   .navbar-light .navbar-toggler-icon {
        background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' width='30' height='30' viewBox='0 0 30 30'%3e%3cpath stroke='rgba(0, 0, 0, 0.5)' stroke-linecap='round' stroke-miterlimit='10' stroke-width='2' d='M4 7h22M4 15h22M4 23h22'/%3e%3c/svg%3e");
   }
   

3. copy the snippet and paste it in your custom CSS

4. change the stroke='rgba(0, 0, 0, 0.5)' value to your preferred rgba value

Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.

import numpy as np 
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)

data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)

sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y)) 

X_train, X_test = X[train_index], X[test_index] 
y_train, y_test = y[train_index], y[test_index]

To hide the grid column

jQuery("#validGrid").jqGrid('hideCol',str);

If that's all what you want to do, you don't need to convert it into an array. You can just access it as:

string myData=yourDataTable.Rows[0][1].ToString();//Gives you USA

Pattern satisfy, these below criteria

1. Password Length 8 and Maximum 15 character
2. Require Unique Chars
3. Require Digit
4. Require Lower Case
5. Require Upper Case

^(?!.*([A-Za-z0-9]))(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,15}$

Here is specifically what worked for me only when the Excel file being queried was not open and when running the SQL Server Service as me [as a user that has access to the file system].

shape is a tuple that gives you an indication of the number of dimensions in the array. So in your case, since the index value of Y.shape[0] is 0, your are working along the first dimension of your array.

From http://www.scipy.org/Tentative_NumPy_Tutorial#head-62ef2d3c0a5b4b7d6fdc48e4a60fe48b1ffe5006

 An array has a shape given by the number of elements along each axis:
 >>> a = floor(10*random.random((3,4)))

 >>> a
 array([[ 7.,  5.,  9.,  3.],
        [ 7.,  2.,  7.,  8.],
        [ 6.,  8.,  3.,  2.]])

 >>> a.shape
 (3, 4)

and http://www.scipy.org/Numpy_Example_List#shape has some more examples.

The solution env TZ='Europe/Amsterdam' node server.js from @uhef works in cases where your app doesn't work with forked process, but when you are working with forked process, specially when you launch your app with a building tool like gulp , the command gulp will take the env values, but the process created by gulp not (your app).

To solve this, you have to do:

$ export TZ="Europe/Amsterdam"; gulp myTask

This will set the TZ environment variable for all the process started in the console you are working on, included all the subsequents process executed after the gulp command in the same console without the need to execute them with the prefix export TZ="Europe/Amsterdam"; again.

you can use FormData

take look at my snippet from MVC

var fd = new FormData();
fd.append("ProfilePicture", $("#mydropzone")[0].files[0]);// getting value from form feleds 
d.append("id", @(((User) Session["User"]).ID));// getting value from session

$.ajax({
    url: '@Url.Action("ChangeUserPicture", "User")',
    dataType: "json",
    data: fd,//here is your data
    processData: false,
    contentType: false,
    type: 'post',
    success: function(data) {},

You could use the head instead of cat:

head -n1 /etc/*release | awk '{print $1}'

Building on @rocksportrocker solution, It would make sense to dill when sending and RECVing the results.

In IE11, you can see local storage in console on dev tools:

1. Show dev tools (press F12)
2. Click "Console" or press Ctrl+2
3. Type localStorage and press Enter

Also, if you need to clear the localStorage, type localStorage.clear() on console.

MATLAB is a popular and widely adapted piece of a sophisticated software package. It'd be a mistake to think it's merely a math software since it has a wide range of "toolboxes". I recently used Matplotlib to plot some data from a database and it did the job without needing all the bells and whistles of MATLAB. However, it may not be proper to compare Python and MATLAB in every situation. As with everything else the decision depends on what you need to do.

I used MATLAB in undergrad for control systems design and simulation and also for image processing in grad school. For these fields MATLAB makes the most sense because of the powerful control and image processing toolboxes. As everyone mentioned, array operations, which are used in every MATLAB script you'd need to write, are very easy with MATLAB.

Another nice thing about MATLAB is that it's very easy and fast to do prototyping and trying out ideas using the built in toolbox functions. For instance, it takes no effort to import an image and compute it's histogram or do some simple processing on it. One disadvantage of MATLAB could be it's speed because of its interpreted nature. However, if one really needs speed than he can choose to implement the tested logic in C/C++, etc.

For further comparison with Python, I can say that MATLAB provides a full package for you to do your work without the need of looking around for external libraries and implementing extra functions.

One last point about MATLAB which I see is not mentioned in the answers here is that it has a very powerful visual modeling/simulation environment called Simulink. It's easier to design and simulate larger systems with Simulink.

Finally, again, it all depends on the problem you need to solve. If your problem domain can make use of one of MATLAB's toolboxes and you have access to MATLAB then you can be sure that you'll have the right tool to solve it.

when you want to use your data existing in your data frame as y value, you must add stat = "identity" in mapping parameter. Function geom_bar have default y value. For example,

ggplot(data_country)+
  geom_bar(mapping = aes(x = country, y = conversion_rate), stat = "identity")

I believe git diff <current-branchname>..stash@{0} is the most intuitive way to compare the changes between the local working tree and the most recent stash. Replace stash@{0} with the applicable stash number as needed.

Beware that git diff stash@{0} may produce misleading results. If the two histories of your stash and current branch have diverged, the diff will look like you’re adding all the new stuff in your stash and removing everything unique to the current branch.

answer based on the git book

Also, note that double dot .. and triple dot ... specify different commit comparisons, and I am referring to the double dot for this answer. See the git book for details

You cannot use a select statement that assigns values to variables to also return data to the user The below code will work fine, because i have declared 1 local variable and that variable is used in select statement.

 Begin
    DECLARE @name nvarchar(max)
    select @name=PolicyHolderName from Table
    select @name
    END

The below code will throw error "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations" Because we are retriving data(PolicyHolderAddress) from table, but error says data-retrieval operation is not allowed when you use some local variable as part of select statement.

 Begin
    DECLARE @name nvarchar(max)
    select 
       @name = PolicyHolderName,
       PolicyHolderAddress 
    from Table
 END

The the above code can be corrected like below,

Begin
    DECLARE @name nvarchar(max)
    DECLARE @address varchar(100)
    select 
       @name = PolicyHolderName,
       @address = PolicyHolderAddress 
    from Table
END

So either remove the data-retrieval operation or add extra local variable. This will resolve the error.

To append different text to the end of each line, you can use the plugin ConyEdit to do this.
With ConyEdit running in the background, follow these steps.

1. use the command line cc.gl a to get lines and store in an array named a.
2. use the command line cc.aal //$a to append after each line, using the contents of array a.

Example

First Declare a variable to store filenames (to use them later):

var myfiles = [];

Open File Dialog

$('#browseBtn').click(function() {
    $('<input type="file" multiple>').on('change', function () {
        myfiles = this.files; //save selected files to the array
        console.log(myfiles); //show them on console
    }).click();
});

i'm posting it, so it may help someone because there are no clear instructions on the internet to how to store filenames into an array!

pd.wide_to_long

You can add a prefix to your year columns and then feed directly to pd.wide_to_long. I won't pretend this is efficient, but it may in certain situations be more convenient than pd.melt, e.g. when your columns already have an appropriate prefix.

df.columns = np.hstack((df.columns[:2], df.columns[2:].map(lambda x: f'Value{x}')))

res = pd.wide_to_long(df, stubnames=['Value'], i='name', j='Date').reset_index()\
        .sort_values(['location', 'name'])

print(res)

   name        Date location  Value
0  test    Jan-2010        A     12
2  test    Feb-2010        A     20
4  test  March-2010        A     30
1   foo    Jan-2010        B     18
3   foo    Feb-2010        B     20
5   foo  March-2010        B     25

SELECT @var = col1,
       @var2 = col2

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

NOTE: The accepted answer was correct in early versions of Go. See the highest voted answer contains the more recent idiomatic way to achieve this.

There is function ReadLine in package bufio.

Please note that if the line does not fit into the read buffer, the function will return an incomplete line. If you want to always read a whole line in your program by a single call to a function, you will need to encapsulate the ReadLine function into your own function which calls ReadLine in a for-loop.

bufio.ReadString('\n') isn't fully equivalent to ReadLine because ReadString is unable to handle the case when the last line of a file does not end with the newline character.

Besides changing it to Console (/SUBSYSTEM:CONSOLE) as others have said, you may need to change the entry point in Properties -> Linker -> Advanced -> Entry Point. Set it to mainCRTStartup.

It seems that Visual Studio might be searching for the WinMain function instead of main, if you don't specify otherwise.

If you want a quick-and-dirty one liner, use this:

fs.existsSync("directory") || fs.mkdirSync("directory");

I have a Joomla Module that displays stuff... and I want to be able to share that stuff on facebook and not the Page's Title Meta Description... so my workaround is to have a secret .php file on the server that gets executed when it detects the FB's

$_SERVER['HTTP_USER_AGENT']

if($_SERVER['HTTP_USER_AGENT'] != 'facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)') {
    echo 'Direct Access';
} else {
    echo 'FB Accessed';
}

and pass variables with the URL that formats that particular page with the title and meta desciption of the item I want to share from my joomla module...

a name="fb_share" share_url="MYURL/sharer.php?title=TITLE&desc=DESC"

Trick: If you are targeting version 22 or below, your application will request all permissions at install time just as it would on any device running an OS below Marshmallow

you must create a background.xml in res/drawable this code

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFF" />
<corners android:radius="6dp" />
<stroke
    android:width="6dp"
    android:color="@android:color/white" />
<padding
    android:bottom="6dp"
    android:left="6dp"
    android:right="6dp"
    android:top="6dp" />
</shape>

You can use this small library: https://github.com/ledfusion/php-rest-curl

Making a call is as simple as:

// GET
$result = RestCurl::get($URL, array('id' => 12345678));

// POST
$result = RestCurl::post($URL, array('name' => 'John'));

// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));

// DELETE
$result = RestCurl::delete($URL); 

And for the $result variable:

• $result['status'] is the HTTP response code
• $result['data'] an array with the JSON response parsed
• $result['header'] a string with the response headers

Thanks guys, this really saved my day too. I antecedently pressed on skip break points, if you did the same this will result on break point appearing with a backslash icon on them.

To bring it back to normal:

1. Switch to Debug perspective.
2. press on the breakpoints view tap -->> upper right hand corner of the screen, you also can go there by Window->show view-> breakpoints.
3. 5th icon from the left you will see break point with backslash. press on that one.

To confirm, try putting break point on any line, and it should appear normally.
