If you're on C# 7, you should consider using value tuples as your composite key. Value tuples typically offer better performance than the traditional reference tuples (Tuple<T1, …>) since value tuples are value types (structs), not reference types, so they avoid the memory allocation and garbage collection costs. Also, they offer conciser and more intuitive syntax, allowing for their fields to be named if you so wish. They also implement the IEquatable<T> interface needed for the dictionary.

var dict = new Dictionary<(int PersonId, int LocationId, int SubjectId), string>();
dict.Add((3, 6, 9), "ABC");
dict.Add((PersonId: 4, LocationId: 9, SubjectId: 10), "XYZ");
var personIds = dict.Keys.Select(k => k.PersonId).Distinct().ToList();

I think this would do the trick:

function get_wp_installation()
{
    $full_path = getcwd();
    $ar = explode("wp-", $full_path);
    return $ar[0];
}

I have tried both of online jsbeautifier(jsbeautifier, jsnice), these tools gave me beautiful js code,

but couldn't copy for very large js (must be bug, when i copy, copied buffer contains only one character '-').

I found that only working solution was prettyjs:

I know you said you would prefer a GUI, but the commandline tools will do the work nicely. See GnuWin for a port of unix tools to Windows. You'd need the patch command, obviously ;-)

You might run into a problem with the line termination, though. The GnuWin port will assume that the patchfile has DOS style line termination (CR/LF). Try to open the patchfile in a reasonably smart editor and it will convert it for you.

Nodejs's installation adds nodejs to the path in the environment properties incorrectly.

By default it adds the following to the path:

C:\Program Files\nodejs\

The ending \ is unnecessary. Remove the \ and everything will be beautiful again.

Since none of the solutions flying around really met our requirements, we came up with a simple jQuery plugin called jQuery-ClearSearch -

using it is as easy as:

<input class="clearable" type="text" placeholder="search">

<script type="text/javascript">
    $('.clearable').clearSearch();
</script>

? Example: http://jsfiddle.net/wldaunfr/FERw3/

Use korn shell, in bash you may have to compare the decimal part separately

#!/bin/ksh
X=0.2
Y=0.2
echo $X
echo $Y

if [[ $X -lt $Y ]]
then
     echo "X is less than Y"
elif [[ $X -gt $Y ]]
then
     echo "X is greater than Y"
elif [[ $X -eq $Y ]]
then
     echo "X is equal to Y"
fi

I had the same issue.

My solution is to first create a table from the non updatable query and then do the update from table to table and it works.

It's impossible. You can only find and access views that are currently running. If you want to check the value of ex. TextView used in previus activity you must save the value is SharedPreferences, database, file or pass by Intent.

<img src="/images/yourfile.png">

Store your files in public/images directory.

In most cases, the %USERNAME% variable will be what you want.

echo %USERNAME%

However, if you're running an elevated cmd shell, then %USERNAME% will report the administrator name instead of your own user name. If you want to know the latter, run:

for /f "tokens=2" %u in ('query session ^| findstr /R "^>"') do @echo %u

try this within your if statements:

Application.DisplayAlerts = False
Worksheets(“Sheetname”).Delete
Application.DisplayAlerts = True

Works for Win7 Enterprise and Win10 Enterprise

@if DEFINED SESSIONNAME (
    @echo.
    @echo You must right click to "Run as administrator"
    @echo Try again
    @echo.
    @pause
    @goto :EOF
)

If you need change slider values from several input, use it:

html:

<input type="text" id="amount">
<input type="text" id="amount2">
<div id="slider-range"></div>

js:

    $( "#slider-range" ).slider({
    range: true,
    min: 0,
    max: 217,
    values: [ 0, 217 ],
    slide: function( event, ui ) {
        $( "#amount" ).val( ui.values[ 0 ] );
        $( "#amount2" ).val( ui.values[ 1 ] );
    }
    });

$("#amount").change(function() {
    $("#slider-range").slider('values',0,$(this).val());
});
$("#amount2").change(function() {
    $("#slider-range").slider('values',1,$(this).val());
});

If it's specifically zero length integers, then you want something like

is.integer0 <- function(x)
{
  is.integer(x) && length(x) == 0L
}

Check it with:

is.integer0(integer(0)) #TRUE
is.integer0(0L)         #FALSE
is.integer0(numeric(0)) #FALSE

You can also use assertive for this.

library(assertive)
x <- integer(0)
assert_is_integer(x)
assert_is_empty(x)
x <- 0L
assert_is_integer(x)
assert_is_empty(x)
## Error: is_empty : x has length 1, not 0.
x <- numeric(0)
assert_is_integer(x)
assert_is_empty(x)
## Error: is_integer : x is not of class 'integer'; it has class 'numeric'.

I'm guessing you probably want to bind a "click" event to a number of radio buttons, read the value of the clicked radiobutton and depending on the value, disable/enable a checkbox and or textbox.

function enableInput(class){
    $('.' + class + ':input').attr('disabled', false);
}

function disableInput(class){
    $('.' + class + ':input').attr('disabled', true);
}

$(document).ready(function(){
    $(".changeBoxes").click(function(event){
        var value = $(this).val();
        if(value == 'x'){
            enableInput('foo'); //with class foo
            enableInput('bar'); //with class bar
        }else{
            disableInput('foo'); //with class foo
            disableInput('bar'); //with class bar
        }
    });
});

SP is the stack register a shortcut for typing r13. LR is the link register a shortcut for r14. And PC is the program counter a shortcut for typing r15.

When you perform a call, called a branch link instruction, bl, the return address is placed in r14, the link register. the program counter pc is changed to the address you are branching to.

There are a few stack pointers in the traditional ARM cores (the cortex-m series being an exception) when you hit an interrupt for example you are using a different stack than when running in the foreground, you dont have to change your code just use sp or r13 as normal the hardware has done the switch for you and uses the correct one when it decodes the instructions.

The traditional ARM instruction set (not thumb) gives you the freedom to use the stack in a grows up from lower addresses to higher addresses or grows down from high address to low addresses. the compilers and most folks set the stack pointer high and have it grow down from high addresses to lower addresses. For example maybe you have ram from 0x20000000 to 0x20008000 you set your linker script to build your program to run/use 0x20000000 and set your stack pointer to 0x20008000 in your startup code, at least the system/user stack pointer, you have to divide up the memory for other stacks if you need/use them.

Stack is just memory. Processors normally have special memory read/write instructions that are PC based and some that are stack based. The stack ones at a minimum are usually named push and pop but dont have to be (as with the traditional arm instructions).

If you go to http://github.com/lsasim I created a teaching processor and have an assembly language tutorial. Somewhere in there I go through a discussion about stacks. It is NOT an arm processor but the story is the same it should translate directly to what you are trying to understand on the arm or most other processors.

Say for example you have 20 variables you need in your program but only 16 registers minus at least three of them (sp, lr, pc) that are special purpose. You are going to have to keep some of your variables in ram. Lets say that r5 holds a variable that you use often enough that you dont want to keep it in ram, but there is one section of code where you really need another register to do something and r5 is not being used, you can save r5 on the stack with minimal effort while you reuse r5 for something else, then later, easily, restore it.

Traditional (well not all the way back to the beginning) arm syntax:

...
stmdb r13!,{r5}
...temporarily use r5 for something else...
ldmia r13!,{r5}
...

stm is store multiple you can save more than one register at a time, up to all of them in one instruction.

db means decrement before, this is a downward moving stack from high addresses to lower addresses.

You can use r13 or sp here to indicate the stack pointer. This particular instruction is not limited to stack operations, can be used for other things.

The ! means update the r13 register with the new address after it completes, here again stm can be used for non-stack operations so you might not want to change the base address register, leave the ! off in that case.

Then in the brackets { } list the registers you want to save, comma separated.

ldmia is the reverse, ldm means load multiple. ia means increment after and the rest is the same as stm

So if your stack pointer were at 0x20008000 when you hit the stmdb instruction seeing as there is one 32 bit register in the list it will decrement before it uses it the value in r13 so 0x20007FFC then it writes r5 to 0x20007FFC in memory and saves the value 0x20007FFC in r13. Later, assuming you have no bugs when you get to the ldmia instruction r13 has 0x20007FFC in it there is a single register in the list r5. So it reads memory at 0x20007FFC puts that value in r5, ia means increment after so 0x20007FFC increments one register size to 0x20008000 and the ! means write that number to r13 to complete the instruction.

Why would you use the stack instead of just a fixed memory location? Well the beauty of the above is that r13 can be anywhere it could be 0x20007654 when you run that code or 0x20002000 or whatever and the code still functions, even better if you use that code in a loop or with recursion it works and for each level of recursion you go you save a new copy of r5, you might have 30 saved copies depending on where you are in that loop. and as it unrolls it puts all the copies back as desired. with a single fixed memory location that doesnt work. This translates directly to C code as an example:

void myfun ( void )
{
   int somedata;
}

In a C program like that the variable somedata lives on the stack, if you called myfun recursively you would have multiple copies of the value for somedata depending on how deep in the recursion. Also since that variable is only used within the function and is not needed elsewhere then you perhaps dont want to burn an amount of system memory for that variable for the life of the program you only want those bytes when in that function and free that memory when not in that function. that is what a stack is used for.

A global variable would not be found on the stack.

Going back...

Say you wanted to implement and call that function you would have some code/function you are in when you call the myfun function. The myfun function wants to use r5 and r6 when it is operating on something but it doesnt want to trash whatever someone called it was using r5 and r6 for so for the duration of myfun() you would want to save those registers on the stack. Likewise if you look into the branch link instruction (bl) and the link register lr (r14) there is only one link register, if you call a function from a function you will need to save the link register on each call otherwise you cant return.

...
bl myfun
    <--- the return from my fun returns here
...


myfun:
stmdb sp!,{r5,r6,lr}
sub sp,#4 <--- make room for the somedata variable
...
some code here that uses r5 and r6
bl more_fun <-- this modifies lr, if we didnt save lr we wouldnt be able to return from myfun
   <---- more_fun() returns here
...
add sp,#4 <-- take back the stack memory we allocated for the somedata variable
ldmia sp!,{r5,r6,lr}
mov pc,lr <---- return to whomever called myfun.

So hopefully you can see both the stack usage and link register. Other processors do the same kinds of things in a different way. for example some will put the return value on the stack and when you execute the return function it knows where to return to by pulling a value off of the stack. Compilers C/C++, etc will normally have a "calling convention" or application interface (ABI and EABI are names for the ones ARM has defined). if every function follows the calling convention, puts parameters it is passing to functions being called in the right registers or on the stack per the convention. And each function follows the rules as to what registers it does not have to preserve the contents of and what registers it has to preserve the contents of then you can have functions call functions call functions and do recursion and all kinds of things, so long as the stack does not go so deep that it runs into the memory used for globals and the heap and such, you can call functions and return from them all day long. The above implementation of myfun is very similar to what you would see a compiler produce.

ARM has many cores now and a few instruction sets the cortex-m series works a little differently as far as not having a bunch of modes and different stack pointers. And when executing thumb instructions in thumb mode you use the push and pop instructions which do not give you the freedom to use any register like stm it only uses r13 (sp) and you cannot save all the registers only a specific subset of them. the popular arm assemblers allow you to use

push {r5,r6}
...
pop {r5,r6}

in arm code as well as thumb code. For the arm code it encodes the proper stmdb and ldmia. (in thumb mode you also dont have the choice as to when and where you use db, decrement before, and ia, increment after).

No you absolutly do not have to use the same registers and you dont have to pair up the same number of registers.

push {r5,r6,r7}
...
pop {r2,r3}
...
pop {r1}

assuming there is no other stack pointer modifications in between those instructions if you remember the sp is going to be decremented 12 bytes for the push lets say from 0x1000 to 0x0FF4, r5 will be written to 0xFF4, r6 to 0xFF8 and r7 to 0xFFC the stack pointer will change to 0x0FF4. the first pop will take the value at 0x0FF4 and put that in r2 then the value at 0x0FF8 and put that in r3 the stack pointer gets the value 0x0FFC. later the last pop, the sp is 0x0FFC that is read and the value placed in r1, the stack pointer then gets the value 0x1000, where it started.

The ARM ARM, ARM Architectural Reference Manual (infocenter.arm.com, reference manuals, find the one for ARMv5 and download it, this is the traditional ARM ARM with ARM and thumb instructions) contains pseudo code for the ldm and stm ARM istructions for the complete picture as to how these are used. Likewise well the whole book is about the arm and how to program it. Up front the programmers model chapter walks you through all of the registers in all of the modes, etc.

If you are programming an ARM processor you should start by determining (the chip vendor should tell you, ARM does not make chips it makes cores that chip vendors put in their chips) exactly which core you have. Then go to the arm website and find the ARM ARM for that family and find the TRM (technical reference manual) for the specific core including revision if the vendor has supplied that (r2p0 means revision 2.0 (two point zero, 2p0)), even if there is a newer rev, use the manual that goes with the one the vendor used in their design. Not every core supports every instruction or mode the TRM tells you the modes and instructions supported the ARM ARM throws a blanket over the features for the whole family of processors that that core lives in. Note that the ARM7TDMI is an ARMv4 NOT an ARMv7 likewise the ARM9 is not an ARMv9. ARMvNUMBER is the family name ARM7, ARM11 without a v is the core name. The newer cores have names like Cortex and mpcore instead of the ARMNUMBER thing, which reduces confusion. Of course they had to add the confusion back by making an ARMv7-m (cortex-MNUMBER) and the ARMv7-a (Cortex-ANUMBER) which are very different families, one is for heavy loads, desktops, laptops, etc the other is for microcontrollers, clocks and blinking lights on a coffee maker and things like that. google beagleboard (Cortex-A) and the stm32 value line discovery board (Cortex-M) to get a feel for the differences. Or even the open-rd.org board which uses multiple cores at more than a gigahertz or the newer tegra 2 from nvidia, same deal super scaler, muti core, multi gigahertz. A cortex-m barely brakes the 100MHz barrier and has memory measured in kbytes although it probably runs of a battery for months if you wanted it to where a cortex-a not so much.

sorry for the very long post, hope it is useful.

On EF core you cannot create Indexes using data annotations.But you can do it using the Fluent API.

Like this inside your {Db}Context.cs:

protected override void OnModelCreating(ModelBuilder builder)
{
    builder.Entity<User>()
        .HasIndex(u => u.Email)
        .IsUnique();
}

...or if you're using the overload with the buildAction:

protected override void OnModelCreating(ModelBuilder builder)
{
    builder.Entity<User>(entity => {
        entity.HasIndex(e => e.Email).IsUnique();
    });
}

You can read more about it here : Indexes

Almost all of the python files should live in their respective folders (C:\Python26 and C:\Python27). Some installers (ActiveState) will also associate .py* files and add the python path to %PATH% with an install if you tick the "use this as the default installation" box.

EDIT: I've added one more option for bootstrap sidebars.

There are actually three manners in which you can make a bootstrap 3 sidebar. I tried to keep the code as simple as possible.

Fixed sidebar

Here you can see a demo of a simple fixed sidebar I've developed with the same height as the page

Sidebar in a column

I've also developed a rather simple column sidebar that works in a two or three column page inside a container. It takes the length of the longest column. Here you can see a demo

Dashboard

If you google bootstrap dashboard, you can find multiple suitable dashboard, such as this one. However, most of them require a lot of coding. I've developed a dashboard that works without additional javascript (next to the bootstrap javascript). Here is a demo

For all three examples you off course have to include the jquery, bootstrap css, js and theme.css files.

Slidebar

If you want the sidebar to hide on pressing a button this is also possible with only a little javascript.Here is a demo

For simple array members like that, you can use JSON.parse.

var listValues = "[{\"ComplianceTaskID\":75305,\"RequirementTypeID\":4,\"MissedRequirement\":\"Initial Photo Upload NRP\",\"TimeOverdueInMinutes\":null}]";

var array = JSON.parse("[" + listValues + "]");

This gives you an Array of numbers.

now you variable value is like array.length=1

Value output

array[0].ComplianceTaskID
array[0].RequirementTypeID
array[0].MissedRequirement
array[0].TimeOverdueInMinutes

You have to send - (void)selectRow:(NSInteger)row inComponent:(NSInteger)component animated:(BOOL)animated to the picker view before it appears. The documentation states that the method selectedRowInComp... will give -1, thus it is possible that the picker view is in a state with no selected row. It turns out to be in that state when created.

<?php
namespace CMS;
class Model {
  const _class = __CLASS__;
}

echo Model::_class; // will return 'CMS\Model'

I have edited the function for you,

void readFile()
{
    ifstream file;
    file.open ("program.txt");
    if (!file.is_open()) return;

    string word;
    while (file >> word)
    {
        cout<< word << '\n';
    }
}

To link from a page to another section of the page, I navigate through the page depending on the page's location to the other, at the URL bar, and add the #id. So what I mean;

<a href = "../#the_part_that_you_want">This takes you #the_part_that_you_want at the page before</a>

In C, using a previously undeclared function constitutes an implicit declaration of the function. In an implicit declaration, the return type is int if I recall correctly. Now, GCC has built-in definitions for some standard functions. If an implicit declaration does not match the built-in definition, you get this warning.

To fix the problem, you have to declare the functions before using them; normally you do this by including the appropriate header. I recommend not to use the -fno-builtin-* flags if possible.

Instead of stdlib.h, you should try:

#include <string.h>

That's where strcpy and strncpy are defined, at least according to the strcpy(2) man page.

The exit function is defined in stdlib.h, though, so I don't know what's going on there.

After lots of tests, following code works for me in Typescreipt

 export function ReplaceNewline(input: string) {
    var newline = String.fromCharCode(13, 10);
    return ReplaceAll(input, "<br>", newline.toString());
}
export function ReplaceAll(str, find, replace) {
    return str.replace(new RegExp(find, 'g'), replace);
}

Use a ValueConverter

[ValueConversion(typeof(string), typeof(String))]
public class MyConverter: IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return string.Format("{0}:{1}", (string) value, (string) parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {

        return DependencyProperty.UnsetValue;
    }
}

and in the markup

<src:MyConverter x:Key="MyConverter"/>

. . .

<TextBlock Text="{Binding Name, Converter={StaticResource MyConverter Parameter=ID}}" />

Try this from your shell:

$ od -A n -t d -N 1 /dev/urandom

Here, -t d specifies that the output format should be signed decimal; -N 1 says to read one byte from /dev/urandom.

this approach works on firefox, chrome and IE. hope it helps someone:

var comp = document.getElementById('yourCompId');
try { //in firefox
    comp.click();
    return;
} catch(ex) {}
try { // in chrome
    if(document.createEvent) {
        var e = document.createEvent('MouseEvents');
        e.initEvent( 'click', true, true );
        comp.dispatchEvent(e);
        return;
    }
} catch(ex) {}
try { // in IE
    if(document.createEventObject) {
         var evObj = document.createEventObject();
         comp.fireEvent("onclick", evObj);
         return;
    }
} catch(ex) {}

This is the idiom I've always used to get a modified copy of a string without changing the original:

(my $newstring = $oldstring) =~ s/foo/bar/g;

In perl 5.14.0 or later, you can use the new /r non-destructive substitution modifier:

my $newstring = $oldstring =~ s/foo/bar/gr; 

NOTE:
The above solutions work without g too. They also work with any other modifiers.

What makes jQuery easy to use is that you don't have to apply attributes to each element. The jQuery object contains an array of elements, and the methods of the jQuery object applies the same attributes to all the elements in the array.

There is also a shorter form for $(document).ready(function(){...}) in $(function(){...}).

So, this is all you need:

$(function(){
  $('div.easy_editor').css('border','9px solid red');
});

If you want the code to work for any element with that class, you can just specify the class in the selector without the tag name:

$(function(){
  $('.easy_editor').css('border','9px solid red');
});

You can download ip-tables from MaxMind:

http://www.maxmind.com/app/geolite

Import the CSV to your database (make sure to create an index for ip_long_from + ip_long_to). Then you can simply do:

$iplong = ip2long($_SERVER['REMOTE_ADDR']);

// should use mysqli with prepared statements etc, but just an example
mysql_query("
    SELECT country
    FROM ip_table
    WHERE $iplong BETWEEN ip_long_from AND ip_long_to
    LIMIT 1
");

If we see logically programming language and scripting language so this is 99.09% same . because we use same concept like loop , control condition ,variable and all so we can say yes both are same but there is only one thing is different between them that is in C/C++ and other programming language we compile the code before execution . but in the PHP , JavaScript and other scripting language we don't need to compile we directly execute in the browser.

Some answers already pointed out background-size: cover is useful in the case, but none points out the browser support details. Here it is:

Add this CSS into your stylesheet:

body {
    background: url(background.jpg) no-repeat center center fixed;
    background-size: cover; /* for IE9+, Safari 4.1+, Chrome 3.0+, Firefox 3.6+ */
    -webkit-background-size: cover; /* for Safari 3.0 - 4.0 , Chrome 1.0 - 3.0 */
    -moz-background-size: cover; /* optional for Firefox 3.6 */ 
    -o-background-size: cover; /* for Opera 9.5 */
    margin: 0; /* to remove the default white margin of body */
    padding: 0; /* to remove the default white margin of body */
}

-moz-background-size: cover; is optional for Firefox, as Firefox starts supporting the value cover since version 3.6. If you need to support Konqueror 3.5.4+ as well, add -khtml-background-size: cover;.

As you're using CSS3, it's suggested to change your DOCTYPE to HTML5. Also, HTML5 CSS Reset stylesheet is suggested to be added BEFORE your our stylesheet to provide a consistent look & feel for modern browsers.

Reference: background-size at MDN

If you ever need to support old browsers like IE 8 or below, you can still go for Javascript way (scroll down to jQuery section)

Last, if you predict your users will use mobile phones to browse your website, do not use the same background image for mobile web, as your desktop image is probably large in file size, which will be a burden to mobile network usage. Use media query to branch CSS.

Or you can use:

ssh -oStrictHostKeyChecking=no host

This will be insecure (man in the middle attacks) but easiest solution.

The better way to do that is to generate correct mappings between host and ip address, so ssh will not complain:

#!/bin/bash

for domain in "github.com" "bitbucket.org"; do
    sed -i "/$domain/d" ~/.ssh/known_hosts
    line=$(ssh-keyscan $domain,`nslookup $domain | awk '/^Address: / { print $2 ; exit }'`)
    echo $line >> ~/.ssh/known_hosts
done

Excerpt from gist.

Have you tried editing the shell entry in account settings.

Go to the Accounts preferences, unlock, and right-click on your user account for the Advanced Settings dialog. Your shell should be /bin/zsh, and you can edit that invocation appropriately (i.e. add the --login argument).

I would try to fix saturation and lumination to maximum and focus on hue only. As I see it, H can go from 0 to 255 and then wraps around. Now if you wanted two contrasting colours you would take the opposite sides of this ring, i.e. 0 and 128. If you wanted 4 colours, you would take some separated by 1/4 of the 256 length of the circle, i.e. 0, 64,128,192. And of course, as others suggested when you need N colours, you could just separate them by 256/N.

What I would add to this idea is to use a reversed representation of a binary number to form this sequence. Look at this:

0 = 00000000  after reversal is 00000000 = 0
1 = 00000001  after reversal is 10000000 = 128
2 = 00000010  after reversal is 01000000 = 64
3 = 00000011  after reversal is 11000000 = 192

... this way if you need N different colours you could just take first N numbers, reverse them, and you get as much distant points as possible (for N being power of two) while at the same time preserving that each prefix of the sequence differs a lot.

This was an important goal in my use case, as I had a chart where colors were sorted by area covered by this colour. I wanted the largest areas of the chart to have large contrast, and I was ok with some small areas to have colours similar to those from top 10, as it was obvious for the reader which one is which one by just observing the area.

You can use this:

SET FEEDBACK OFF;
SET SERVEROUTPUT ON;

DECLARE
  V_START_DATE  CHAR(17) := '28/03/16 17:20:00';
  V_END_DATE    CHAR(17) := '30/03/16 17:50:10';
  V_DATE_DIFF   VARCHAR2(17);

BEGIN

SELECT
  (TO_NUMBER( SUBSTR(NUMTODSINTERVAL(TO_DATE(V_END_DATE , 'DD/MM/YY HH24:MI:SS') - TO_DATE(V_START_DATE, 'DD/MM/YY HH24:MI:SS'), 'DAY'), 02, 9)) * 24) +
  (TO_NUMBER( SUBSTR(NUMTODSINTERVAL(TO_DATE(V_END_DATE , 'DD/MM/YY HH24:MI:SS') - TO_DATE(V_START_DATE, 'DD/MM/YY HH24:MI:SS'), 'DAY'), 12, 2)))  || 
              SUBSTR(NUMTODSINTERVAL(TO_DATE(V_END_DATE , 'DD/MM/YY HH24:MI:SS') - TO_DATE(V_START_DATE, 'DD/MM/YY HH24:MI:SS'), 'DAY'), 14, 6) AS "HH24:MI:SS"
  INTO V_DATE_DIFF
FROM 
  DUAL;

DBMS_OUTPUT.PUT_LINE(V_DATE_DIFF);
END;

In my case, Get specific version, even checking both check boxes and undoing all pending changes didn't work.

Checked the work spaces. Edit current workspace. Check all paths. The solution path was incorrect and was pointing to a deleted folder.

Fixed the path and get latest worked fine.

If you convert table field:

1. Define the field so it contains seconds:

    CREATE TABLE IF NOT EXISTS test (
        ...
        field        INTERVAL SECOND(0)
    );
   

2. Extract the value. Remember to cast to int other wise you can get an unpleasant surprise once the intervals are big:

   EXTRACT(EPOCH FROM field)::int

Use OnFocusChangeListener.

For example:

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            hideKeyboard();
        }
    }
});

Update: you also may override onTouchEvent() in your activity and check coordinates of the touch. If coordinates are outside of EditText, then hide the keyboard.

I have my simple method which I have used in college.

line = "I     have            a       nice    day."

end = 1000
while end != 0:
    line.replace("  ", " ")
    end -= 1

This will replace every double space with a single space and will do it 1000 times. It means you can have 2000 extra spaces and will still work. :)

I had this issue in xcode 6 and there is a way to resolve the resize conflicts. If you select your view, at the bottom you will see an icon that looks like |-Δ-|. If you click on it, you're project will resize for different devices.

I didn't have control over the security configuration for the service I was calling into, but got the same error. I was able to fix my client as follows.

1. In the config, set up the security mode:

   <security mode="TransportCredentialOnly">
     <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" />
     <message clientCredentialType="UserName" algorithmSuite="Default" />
   </security>
   

2. In the code, set the proxy class to allow impersonation (I added a reference to a service called customer):

   Customer_PortClient proxy = new Customer_PortClient();
   proxy.ClientCredentials.Windows.AllowedImpersonationLevel =    
            System.Security.Principal.TokenImpersonationLevel.Impersonation;
   

In a nutshell answer.

Usually, you would do something like this:

$post_data = json_encode(array('item' => $post_data));

But, as it seems you want the output to be with "{}", you better make sure to force json_encode() to encode as object, by passing the JSON_FORCE_OBJECT constant.

$post_data = json_encode(array('item' => $post_data), JSON_FORCE_OBJECT);

"{}" brackets specify an object and "[]" are used for arrays according to JSON specification.

try this code:

$('hdntxtbxTaksit').val('test');

Your question is a little unclear...as the part that you indicate you want to bold in Excel is a DataGridView in the import from word method. Do you maybe want to bold the first row in the excel document?

using xl = Microsoft.Office.Interop.Excel;

xl.Range rng = (xl.Range)xlWorkSheet.Rows[0];
rng.Font.Bold = true;

Simple as that!

Use the force, read the source (excerpt from the Priority and Level class compiled, TRACE level was introduced in version 1.2.12):

public final static int OFF_INT = Integer.MAX_VALUE;
public final static int FATAL_INT = 50000;
public final static int ERROR_INT = 40000;
public final static int WARN_INT  = 30000;
public final static int INFO_INT  = 20000;
public final static int DEBUG_INT = 10000;
public static final int TRACE_INT = 5000; 
public final static int ALL_INT = Integer.MIN_VALUE; 

or the log4j API for the Level class, which makes it quite clear.

When the library decides whether to print a certain statement or not, it computes the effective level of the responsible Logger object (based on configuration) and compares it with the LogEvent's level (depends on which method was used in the code – trace/debug/.../fatal). If LogEvent's level is greater or equal to the Logger's level, the LogEvent is sent to appender(s) – "printed". At the core, it all boils down to an integer comparison and this is where these constants come to action.

Latest versions of Excel has a new tool called Slicers. Using slicers in VBA is actually more reliable that .CurrentPage (there have been reports of bugs while looping through numerous filter options). Here is a simple example of how you can select a slicer item (remember to deselect all the non-relevant slicer values):

Sub Step_Thru_SlicerItems2()
Dim slItem As SlicerItem
Dim i As Long
Dim searchName as string

Application.ScreenUpdating = False
searchName="Value1"

    For Each slItem In .VisibleSlicerItems
        If slItem.Name <> .SlicerItems(1).Name Then _
            slItem.Selected = False
        Else
            slItem.Selected = True
        End if
    Next slItem
End Sub

There are also services like SmartKato that would help you out with setting up your dashboards or reports and/or fix your code.

Another option which doesn't have the need to create a custom Model is to use a Tuple<>.

@model Tuple<Person,Order>

It's not as clean as creating a new class which contains both, as per Andi's answer, but it is viable.

I know this is an old question, but I came across a main thread one-liner that I use in both Kotlin and Java. This may not be the best solution for a service, but for calling something that will change the UI inside of a fragment this is extremely simple and obvious.

Java (8):

 getActivity().runOnUiThread(()->{
      //your main thread code
 });

Kotlin:

this.runOnUiThread {
     //your main thread code
}

Use NUMPAD 7 and NUMPAD 9. It will help you.

• First, str in Python is represented in Unicode.
• Second, UTF-8 is an encoding standard to encode Unicode string to bytes. There are many encoding standards out there (e.g. UTF-16, ASCII, SHIFT-JIS, etc.).

When the client sends data to your server and they are using UTF-8, they are sending a bunch of bytes not str.

You received a str because the "library" or "framework" that you are using, has implicitly converted some random bytes to str.

Under the hood, there is just a bunch of bytes. You just need ask the "library" to give you the request content in bytes and you will handle the decoding yourself (if library can't give you then it is trying to do black magic then you shouldn't use it).

• Decode UTF-8 encoded bytes to str: bs.decode('utf-8')
• Encode str to UTF-8 bytes: s.encode('utf-8')

After uncommenting disable_overscan=1 follow my lead. In the link, http://elinux.org/RPiconfig when you search for Video options, you'll also get hdmi_group and hdmi_mode. For, hdmi_group choose 1 if you're using you TV as an video output or choose 2 for monitors. Then in hdmi_mode, you can select the resolution you want from the list. I chose :- hdmi_group=2 hdmi_mode=23 And it worked.

1. in your sample code you must remove the brackets, because it's not a functional assignment; also for documentary reasons I would suggest you use the := notation (see code sample below)

   2. Application.Thisworkbook refers to the book containing the VBA code, not necessarily the book containing the data, so be cautious.

Express the sheet you're working on as a sheet object and pass it, together with a logical variable to the following sub:

Sub SetProtectionMode(MySheet As Worksheet, ProtectionMode As Boolean)

    If ProtectionMode Then
        MySheet.Protect DrawingObjects:=True, Contents:=True, _
                        AllowSorting:=True, AllowFiltering:=True
    Else
        MySheet.Unprotect
    End If
End Sub

Within the .Protect method you can define what you want to allow/disallow. This code block will switch protection on/off - without password in this example, you can add it as a parameter or hardcoded within the Sub. Anyway somewhere the PW will be hardcoded. If you don't want this, just call the Protection Dialog window and let the user decide what to do:

Application.Dialogs(xlDialogProtectDocument).Show

Hope that helps

Good luck - MikeD

Try these:

1. window.location.href = 'http://www.google.com';
2. window.location.assign("http://www.w3schools.com");
3. window.location = 'http://www.google.com';

You are comparing a jQuery object (jQuery('input:first')) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:

if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)

The inArray method returns -1 if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :

if(jQuery.inArray(el,arr) == -1){
    // the element is not in the array
};

Try something like this:

div {
    background-image: url(../img/picture1.jpg);
    height: 30em;
    background-repeat: no-repeat;
    width: 100%;
    background-position: center;
}

Generally we use word count example in hadoop. I will take the same use case and will use map and flatMap and we will see the difference how it is processing the data.

Below is the sample data file.

hadoop is fast
hive is sql on hdfs
spark is superfast
spark is awesome

The above file will be parsed using map and flatMap.

Using map

>>> wc = data.map(lambda line:line.split(" "));
>>> wc.collect()
[u'hadoop is fast', u'hive is sql on hdfs', u'spark is superfast', u'spark is awesome']

Input has 4 lines and output size is 4 as well, i.e., N elements ==> N elements.

Using flatMap

>>> fm = data.flatMap(lambda line:line.split(" "));
>>> fm.collect()
[u'hadoop', u'is', u'fast', u'hive', u'is', u'sql', u'on', u'hdfs', u'spark', u'is', u'superfast', u'spark', u'is', u'awesome']

The output is different from map.

Let's assign 1 as value for each key to get the word count.

• fm: RDD created by using flatMap
• wc: RDD created using map

>>> fm.map(lambda word : (word,1)).collect()
[(u'hadoop', 1), (u'is', 1), (u'fast', 1), (u'hive', 1), (u'is', 1), (u'sql', 1), (u'on', 1), (u'hdfs', 1), (u'spark', 1), (u'is', 1), (u'superfast', 1), (u'spark', 1), (u'is', 1), (u'awesome', 1)]

Whereas flatMap on RDD wc will give the below undesired output:

>>> wc.flatMap(lambda word : (word,1)).collect()
[[u'hadoop', u'is', u'fast'], 1, [u'hive', u'is', u'sql', u'on', u'hdfs'], 1, [u'spark', u'is', u'superfast'], 1, [u'spark', u'is', u'awesome'], 1]

You can't get the word count if map is used instead of flatMap.

As per the definition, difference between map and flatMap is:

map: It returns a new RDD by applying given function to each element of the RDD. Function in map returns only one item.

flatMap: Similar to map, it returns a new RDD by applying a function to each element of the RDD, but output is flattened.

and, for completeness and with regards to this question asking about changing string columns only, there's mutate_if:

data <- cbind(stringVar = sample(c("foo","bar"),10,replace=TRUE),
              data.frame(matrix(sample(1:40), 10, 10, dimnames = list(1:10, LETTERS[1:10]))),stringsAsFactors=FALSE)     

factoredData = data %>% mutate_if(is.character,funs(factor(.)))

Im late to the party, but this worked great for me and the code should explain itself;

<script type="text/javascript">
    function formAJAX(btn){
        var $form = $(btn).closest('[action]');
        var str = $form.find('[name]').serialize();
        $.post($form.attr('action'), str, function(data){
            //do stuff
        });
    }
<script>

HTML:

<tr action="scriptURL.php">
    <td>
        Field 1:<input type="text" name="field1"/>
    </td>
    <td>
        Field 2:<input type="text" name="field2" />
    </td>
    <td><button type="button" onclick="formAJAX(this)">Update</button></td>
</tr>

For Xamarin Users:

If you extends all your activities to a BaseActivity Just add:

this.RequestedOrientation = ScreenOrientation.Portrait;

This will resolve the problem. If you want any particular activity to be in landscape override this in OnActivityCreated. As:

this.Activity.RequestedOrientation = ScreenOrientation.Landscape;

Probably you are in one of the following 2 situations:

1. You didn't add the Maven to the Path
   (run ECHO.%PATH:;= & ECHO.% in cmd to see if you are in this situation).
   • go to Control Panel\User Accounts\User Accounts
     (or click on your photo from the start menu)
   • click Change my environment variables
   • click on New... and add:
     • M2_HOME=<your_path>
     • MAVEN_HOME=%M2_HOME%
     • MAVEN_BIN=%M2_HOME%\bin
   • click on Edit... and add the ;%MAVEN_BIN% at the end of the Path
2. You added it to the Path, but you didn't open a new command prompt.
   • open a new command prompt, because the environment variables are not updated automatically

You can now use Lambda Layers for this matters. Simply add a layer containing the package you need and it will run perfectly.

Follow this post: https://medium.com/@anjanava.biswas/nodejs-runtime-environment-with-aws-lambda-layers-f3914613e20e

A tuple consists of a number of values separated by commas. like

>>> t = 12345, 54321, 'hello!'
>>> t[0]
12345

tuple are index based (and also immutable) in Python.

Here in this case x = rows[1][1] + " " + rows[1][2] have only two index 0, 1 available but you are trying to access the 3rd index.

One main reason we went with Workstation over Player at my job is because we need to run VMs that use a physical disk as their hard drive instead of a virtual disk. Workstation supports using physical disks while Player does not.

This is described here: https://yarnpkg.com/en/docs/cli/add#toc-adding-dependencies

For example:

yarn add https://github.com/novnc/noVNC.git#0613d18

There is difference between collision and duplication. Collision means hashcode and bucket is same, but in duplicate, it will be same hashcode,same bucket, but here equals method come in picture.

Collision detected and you can add element on existing key. but in case of duplication it will replace new value.

If you have access to the registry but the error is still occurred nothing mentioned above wouldn't work. I noted that this problem is only applicable for local project's installation (i.e. if you use -g to global install everything is working fine).

What's resolved the problem for me: just remove an entry regarding a package you're going to install from a project's package.json file. After that next call to npm will work and install the package successfully.

Some even more streamlined overloads for Swift 4:

extension Dictionary {
    static func += (lhs: inout [Key:Value], rhs: [Key:Value]) {
        lhs.merge(rhs){$1}
    }
    static func + (lhs: [Key:Value], rhs: [Key:Value]) -> [Key:Value] {
        return lhs.merging(rhs){$1}
    }
}

It's document.getElementById() and not document.getElementByID(). Check the casing for Id.

Think about the overhead as the time required to manage the threads and coordinate among them. It is a burden if the thread does not have enough task to do. In such a case the overhead cost over come the saved time through using threading and the code takes more time than the sequential one.

I know the answers were correct at the time of asking the question - but since people (like me this minute) still happen to find them wondering why their WildFly 10 was behaving differently, I'd like to give an update for the current Hibernate 5.x version:

In the Hibernate 5.2 User Guide it is stated in chapter 11.2. Applying fetch strategies:

The Hibernate recommendation is to statically mark all associations lazy and to use dynamic fetching strategies for eagerness. This is unfortunately at odds with the JPA specification which defines that all one-to-one and many-to-one associations should be eagerly fetched by default. Hibernate, as a JPA provider, honors that default.

So Hibernate as well behaves like Ashish Agarwal stated above for JPA:

OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER

(see JPA 2.1 Spec)

As an example, I am using a login modal window, where the modal window is the parent, the login form is the child and the login button calls back to the modal parent's close function.

The parent modal contains the function to close the modal. This parent passes the close function to the login child component.

import { Component} from '@angular/core';
import { LoginFormComponent } from './login-form.component'

@Component({
  selector: 'my-modal',
  template: `<modal #modal>
      <login-form (onClose)="onClose($event)" ></login-form>
    </modal>`
})
export class ParentModalComponent {
  modal: {...};

  onClose() {
    this.modal.close();
  }
}

After the child login component submits the login form, it closes the parent modal using the parent's callback function

import { Component, EventEmitter, Output } from '@angular/core';

@Component({
  selector: 'login-form',
  template: `<form (ngSubmit)="onSubmit()" #loginForm="ngForm">
      <button type="submit">Submit</button>
    </form>`
})
export class ChildLoginComponent {
  @Output() onClose = new EventEmitter();
  submitted = false;

  onSubmit() {
    this.onClose.emit();
    this.submitted = true;
  }
}

I'd do it this way:

import random
from string import digits, ascii_uppercase

legals = digits + ascii_uppercase

def rand_string(length, char_set=legals):

    output = ''
    for _ in range(length): output += random.choice(char_set)
    return output

Or just:

def rand_string(length, char_set=legals):

    return ''.join( random.choice(char_set) for _ in range(length) )

In normal winForms, value of Label object is changed by,

myLabel.Text= "Your desired string";

But in WPF Label control, you have to use .content property of Label control for example,

myLabel.Content= "Your desired string";

Another working example in VB.NET:

Public Function base64Encode(ByVal myDataToEncode As String) As String
    Try
        Dim myEncodeData_byte As Byte() = New Byte(myDataToEncode.Length - 1) {}
        myEncodeData_byte = System.Text.Encoding.UTF8.GetBytes(myDataToEncode)
        Dim myEncodedData As String = Convert.ToBase64String(myEncodeData_byte)
        Return myEncodedData
    Catch ex As Exception
        Throw (New Exception("Error in base64Encode" & ex.Message))
    End Try
    '
End Function

1. use single quotes for strings
2. do NOT put single quotes around table names(use ` instead)
3. do NOT put single quotes around numbers (you can, but it's harder to read)
4. do NOT put AND between ORDER BY and LIMIT
5. do NOT put = between ORDER BY, LIMIT keywords and condition

So you query will look like:

SELECT post_datetime 
FROM post 
WHERE type = 'published' 
ORDER BY post_datetime DESC 
LIMIT 3

Spark executor memory is required for running your spark tasks based on the instructions given by your driver program. Basically, it requires more resources that depends on your submitted job.

Executor memory includes memory required for executing the tasks plus overhead memory which should not be greater than the size of JVM and yarn maximum container size.

Add the following parameters in spark-defaults.conf

spar.executor.cores=1

spark.executor.memory=2g

If you using any cluster management tools like cloudera manager or amabari please refresh the cluster configuration for reflecting the latest configs to all nodes in the cluster.

Alternatively, we can pass the executor core and memory value as an argument while running spark-submit command along with class and application path.

Example:

spark-submit \

  --class org.apache.spark.examples.SparkPi \

  --master yarn \

  --deploy-mode cluster \  # can be client for client mode

  --executor-memory 2G \

  --num-executors 5 \

  /path/to/examples.jar \

SELECT pg_size_pretty(pg_database_size('name of database'));

Will give you the total size of a particular database however I don't think you can do all databases within a server.

However you could do this...

DO
$$
DECLARE
r   RECORD;
db_size TEXT;
BEGIN
FOR r in
SELECT datname FROM pg_database
WHERE datistemplate = false
LOOP
db_size:= (SELECT pg_size_pretty(pg_database_size(r.datname)));

RAISE NOTICE 'Database:% , Size:%', r.datname , db_size;

END LOOP;
END;
$$

You could do something like this:

public function __construct($param)
{
    if(is_int($param)) {
         $this->id = $param;
    } elseif(is_object($param)) {
     // do something else
    }
 }

JSON.stringify's third parameter defines white-space insertion for pretty-printing. It can be a string or a number (number of spaces). Node can write to your filesystem with fs. Example:

var fs = require('fs');

fs.writeFile('test.json', JSON.stringify({ a:1, b:2, c:3 }, null, 4));
/* test.json:
{
     "a": 1,
     "b": 2,
     "c": 3,
}
*/

See the JSON.stringify() docs at MDN, Node fs docs

It looks like the answer is at least 12 million if you have a beefy server, your server software is optimized for it, you have enough clients. If you test from one client to one server, the number of port numbers on the client will be one of the obvious resource limits (Each TCP connection is defined by the unique combination of IP and port number at the source and destination).

(You need to run multiple clients as otherwise you hit the 64K limit on port numbers first)

When it comes down to it, this is a classic example of the witticism that "the difference between theory and practise is much larger in practise than in theory" - in practise achieving the higher numbers seems to be a cycle of a. propose specific configuration/architecture/code changes, b. test it till you hit a limit, c. Have I finished? If not then d. work out what was the limiting factor, e. go back to step a (rinse and repeat).

Here is an example with 2 million TCP connections onto a beefy box (128GB RAM and 40 cores) running Phoenix http://www.phoenixframework.org/blog/the-road-to-2-million-websocket-connections - they ended up needing 50 or so reasonably significant servers just to provide the client load (their initial smaller clients maxed out to early, eg "maxed our 4core/15gb box @ 450k clients").

Here is another reference for go this time at 10 million: http://goroutines.com/10m.

This appears to be java based and 12 million connections: https://mrotaru.wordpress.com/2013/06/20/12-million-concurrent-connections-with-migratorydata-websocket-server/

For the record, this is documented in How do I add resources to my JAR? (illustrated for unit tests but the same applies for a "regular" resource):

To add resources to the classpath for your unit tests, you follow the same pattern as you do for adding resources to the JAR except the directory you place resources in is ${basedir}/src/test/resources. At this point you would have a project directory structure that would look like the following:

my-app
|-- pom.xml
`-- src
    |-- main
    |   |-- java
    |   |   `-- com
    |   |       `-- mycompany
    |   |           `-- app
    |   |               `-- App.java
    |   `-- resources
    |       `-- META-INF
    |           |-- application.properties
    `-- test
        |-- java
        |   `-- com
        |       `-- mycompany
        |           `-- app
        |               `-- AppTest.java
        `-- resources
            `-- test.properties

In a unit test you could use a simple snippet of code like the following to access the resource required for testing:

...

// Retrieve resource
InputStream is = getClass().getResourceAsStream("/test.properties" );

// Do something with the resource

...

You can read the data into an array. From there you can do the match in memory, instead of reading one cell at a time.

Pass cell contents into VBA Array

Add a reference to the Outlook object model in the Visual Basic editor. Then you can use the code below to send an email using outlook.

Sub sendOutlookEmail()
Dim oApp As Outlook.Application
Dim oMail As MailItem
Set oApp = CreateObject("Outlook.application")

Set oMail = oApp.CreateItem(olMailItem)
oMail.Body = "Body of the email"
oMail.Subject = "Test Subject"
oMail.To = "[email protected]"
oMail.Send
Set oMail = Nothing
Set oApp = Nothing


End Sub

Just look at the python GUI programming options at http://wiki.python.org/moin/GuiProgramming. But, Consider Wxpython for your GUI application as it is cross platform. And,from above link you could also get some IDE to work upon.

Single quotation marks won't do in that case. You have to add quotation marks around each path and also enclose the whole command in quotation marks:

cmd /C ""C:\Program Files (x86)\WinRar\Rar.exe" a "D:\Hello 2\File.rar" "D:\Hello 2\*.*""

There are two commands which will work in this situation,

root>git reset --hard HEAD~1

root>git push -f

For more git commands refer this page

yourbox{
   position:absolute;
   right:<x>px;
   top  :<x>px;
}

positions it in the right corner. Note, that the position is dependent of the first ancestor-element which is not static positioned!

EDIT:

I updated your fiddle.

Well, overhead is overhead, but yes, not too big.

Also, browsers are sometimes "greedy" about cached files. You could clear cache and/or restart your browser and may see the change. If that fails though...

My cheapo solution is to:

1. Visit your file at http://example.com/favicon.ico in your browser.
2. Delete the favicon.ico from your webroot.
3. Visit http://example.com/favicon.ico again in a browser, verify it's missing.
4. Upload new one to your webroot.
5. Visit http://example.com/favicon.ico again in a browser, verify it's the new one.

If that sequence doesn't work, then something else is going on.

You can test like this:

create table test1(
 id number,
 name varchar2(20)
);

insert into test1 values (1,'abc');
insert into test1 values (1,'abc');

select * from test1;
select count(*) from test1;
select count(1) from test1;
select count(ALL 1) from test1;
select count(DISTINCT 1) from test1;

Also if you know how to make user become the super-user that would be nice also. Thanks!

sudo. su. chmod 04500. (setuid() & seteuid(), but they require you to already be root. E..g. chmod'ed 04***.)

Take care. These can open "interesting" security holes...

Depending on what you are doing, you may not need root. (For instance: I'll often chmod/chown /dev devices (serial ports, etc) (under sudo root) so I can use them from my software without being root. On the other hand, that doesn't work so well when loading/unloading kernel modules...)

Using NAT (the default) this is not possible. Bridged Networking should allow it. If bridged does not work for you (this may be the case when your network adminstration does not allow multiple IP addresses on one physical interface), you could try 'Host-only networking' instead.

For configuration of Host-only here is a quote from the vbox manual(which is pretty good). http://www.virtualbox.org/manual/ch06.html:

For host-only networking, like with internal networking, you may find the DHCP server useful that is built into VirtualBox. This can be enabled to then manage the IP addresses in the host-only network since otherwise you would need to configure all IP addresses statically.

In the VirtualBox graphical user interface, you can configure all these items in the global settings via "File" -> "Settings" -> "Network", which lists all host-only networks which are presently in use. Click on the network name and then on the "Edit" button to the right, and you can modify the adapter and DHCP settings.

For zsh the syntax is slightly different, but still shorter than most answers here:

> str1='mAtCh'
> str2='MaTcH'
> [[ "$str1:u" = "$str2:u" ]] && echo 'Strings Match!'
Strings Match!
>

This will convert both strings to uppercase before the comparison.

Another method makes use zsh's globbing flags, which allows us to directly make use of case-insensitive matching by using the i glob flag:

setopt extendedglob
[[ $str1 = (#i)$str2 ]] && echo "Match success"
[[ $str1 = (#i)match ]] && echo "Match success"

I had the same problem, with which I struggled for few days, reading all the blog posts, watching videos and finally after i changed my uno board, it worked perfectly well. But before I did that, there were a few things I tried, which I think also had an effect.

• Extracted the files to opt folder, change the preference --> behavior --> executable text files --> ask what to do. After that, double clicked arduino on the folder, selected run by terminal
• added user dialout like described in other answers.

Hope this answer helps you.

try (UPDATE)

MemoryStream ms = new MemoryStream(byteArrayIn,0,byteArrayIn.Length);
ms.Position = 0; // this is important
returnImage = Image.FromStream(ms,true);

I had this issue with Excel 2013. I had "freeze panes" set, which caused the problem. The issue was resolved when I removed the frozen panes.

In imports

import re

In run time processing:

RE_TEST = r'test'
if re.match(RE_TEST, 'TeSt', re.IGNORECASE):

It should be mentioned that not using re.compile is wasteful. Every time the above match method is called, the regular expression will be compiled. This is also faulty practice in other programming languages. The below is the better practice.

In app initialization:

self.RE_TEST = re.compile('test', re.IGNORECASE)

In run time processing:

if self.RE_TEST.match('TeSt'):

There is a vcvars32.bat in your Visual Studio installation directory. You can add call cmd.exe at the end of that batch program and launch it. From that shell you can use CMake or cmake-gui and cl.exe would be known to CMake.

An <iframe> gives you a complete window to work with. The most direct way to do what you want is to have your server give you a complete page that only contains the fragment you want to show.

As an alternative, you could just use a simple <div> and use the jQuery "load" function to load the whole page and pluck out just the section you want:

$('#target-div').load('http://www.mywebsite.com/portfolio.php #portfolio-sports');

There may be other things you need to do, and a significant difference is that the content will become part of the main page instead of being segregated into a separate window.

A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =:

HOME=c

An environment variable is a regular variable that has been marked for export to the environment.

export HOME
HOME=c

You can combine the assignment with the export statement.

export HOME=c

body{
    height: 100vh;
} 
.container{
    height: 100%;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet"/>


<div class="container text-center d-flex align-items-center justify-content-center">
        <div>
            <div>
                <h1>Counter</h1>
            </div>
            <div>
                <span>0</span>
            </div>
            <div>
                <button class="btn btn-outline-primary">Decrease</button>
                <button class="btn btn-danger">Reset</button>
                <button class="btn btn-outline-success">Increase</button>
            </div>
        </div>
    </div>

you can do also that way.

Here's an example using the stronger typing. Not sure if it's necessarily the best way though.

static void Main(string[] args)
{
    IList list = new List<int>() { 1, 3, 2, 5, 4, 6, 9, 8, 7 };
    List<int> stronglyTypedList = new List<int>(Cast<int>(list));
    stronglyTypedList.Sort();
}

private static IEnumerable<T> Cast<T>(IEnumerable list)
{
    foreach (T item in list)
    {
        yield return item;
    }
}

The Cast function is just a reimplementation of the extension method that comes with 3.5 written as a normal static method. It is quite ugly and verbose unfortunately.

This can also be achieved using the Lambda based approach of Linq;

var list = ctn.Items
.Where(t=> t.DeliverySelection == true && t.Delivery.SentForDelivery == null)
.OrderBy(t => t.Delivery.SubmissionDate)
.Take(5);

I agree John M has best answer to OP's question. Thought not explictly stated, the apparent purpose is to get a selected file name, whereas other answers return either counts or lists. I would add, however, that the msofiledialogfilepicker might be a better option in this case. ie:

Dim f As object
Set f = Application.FileDialog(msoFileDialogFilePicker)
dim varfile as variant 
f.show
with f
    .allowmultiselect = false
     for each varfile in .selecteditems
        msgbox varfile
     next varfile
end with

Note: the value of varfile will remain the same since multiselect is false (only one item is ever selected). I used its value outside the loop with equal success. It's probably better practice to do it as John M did, however. Also, the folder picker can be used to get a selected folder. I always prefer late binding, but I think the object is native to the default access library, so it may not be necessary here

I did this in Excel 2000.

This statement should be: ms = Round(temp - Int(temp), 3) * 1000

You need to create a custom format for the result cell of [h]:mm:ss.000

I implemented a pinch zoom for my TextView, using this tutorial. The resulting code is this:

private GestureDetector gestureDetector;
private View.OnTouchListener gestureListener;

and in onCreate():

    // Zoom handlers
    gestureDetector = new GestureDetector(new MyGestureDetector());
    gestureListener = new View.OnTouchListener() {

        // We can be in one of these 2 states
        static final int NONE = 0;
        static final int ZOOM = 1;
        int mode = NONE;

        static final int MIN_FONT_SIZE = 10;
        static final int MAX_FONT_SIZE = 50;

        float oldDist = 1f;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            TextView textView = (TextView) findViewById(R.id.text);

            switch (event.getAction() & MotionEvent.ACTION_MASK) {
                case MotionEvent.ACTION_POINTER_DOWN:
                    oldDist = spacing(event);
                    Log.d(TAG, "oldDist=" + oldDist);
                    if (oldDist > 10f) {
                       mode = ZOOM;
                       Log.d(TAG, "mode=ZOOM" );
                    }
                    break;
                case MotionEvent.ACTION_POINTER_UP:
                    mode = NONE;
                    break;
                case MotionEvent.ACTION_MOVE:
                    if (mode == ZOOM) {
                        float newDist = spacing(event);
                        // If you want to tweak font scaling, this is the place to go.
                        if (newDist > 10f) {
                            float scale = newDist / oldDist;

                            if (scale > 1) {
                                scale = 1.1f;
                            } else if (scale < 1) {
                                scale = 0.95f;
                            }

                            float currentSize = textView.getTextSize() * scale;
                            if ((currentSize < MAX_FONT_SIZE && currentSize > MIN_FONT_SIZE)
                                    ||(currentSize >= MAX_FONT_SIZE && scale < 1)
                                    || (currentSize <= MIN_FONT_SIZE && scale > 1)) {
                                textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, currentSize);
                            }
                        }
                    }
                    break;
                }
            return false;
        }

Magic constants 1.1 and 0.95 were chosen empirically (using scale variable for this purpose made my TextView behave kind of weird).

Not clear where My_ConnectionString is coming from in your example, but try this

System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString

like this

Dim DBConnection As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString)

use str

try:
    some_method()
except Exception as e:
    s = str(e)

Also, most exception classes will have an args attribute. Often, args[0] will be an error message.

It should be noted that just using str will return an empty string if there's no error message whereas using repr as pyfunc recommends will at least display the class of the exception. My take is that if you're printing it out, it's for an end user that doesn't care what the class is and just wants an error message.

It really depends on the class of exception that you are dealing with and how it is instantiated. Did you have something in particular in mind?

If I wish to submit a http get request using System.Net.HttpClient there seems to be no api to add parameters, is this correct?

Yes.

Is there any simple api available to build the query string that doesn't involve building a name value collection and url encoding those and then finally concatenating them?

Sure:

var query = HttpUtility.ParseQueryString(string.Empty);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
string queryString = query.ToString();

will give you the expected result:

foo=bar%3c%3e%26-baz&bar=bazinga

You might also find the UriBuilder class useful:

var builder = new UriBuilder("http://example.com");
builder.Port = -1;
var query = HttpUtility.ParseQueryString(builder.Query);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
builder.Query = query.ToString();
string url = builder.ToString();

will give you the expected result:

http://example.com/?foo=bar%3c%3e%26-baz&bar=bazinga

that you could more than safely feed to your HttpClient.GetAsync method.

I see the question has already been answered, but still want to add my 2 cents for the same.

I have also faced similar scenario in which I have to test the execution times for several approaches and hence written a small script, which calls timeit on all functions written in it.

The script is also available as github gist here.

Hope it will help you and others.

You misspelled permission

You will need to configure you IIS (assuming this is the web server your are/will using) allowing access from WLAN/LAN to specific users (or anonymous). Allow IIS trought your firewall if you have one.

Your application won't need to be changed, that's just networking problems ans configuration you will have to face to allow acces only trought LAN and WLAN.

Go to the starting line and type ma (mark "a"). Then go to the last line and enter d'a (delete to mark "a").

That will delete all lines from the current to the marked one (inclusive). It's also compatible with vi as well as vim, on the off chance that your environment is not blessed with the latter.

I can see that the Debugger is retrieving 4 og:image tags from your URL.

The first image is the largest and therefore takes longest to load. Try shrink that first image down or change the order to show a smaller image first.

The only difference I see is that getJSON performs a GET request instead of a POST.

As a workaround, There is a Kotlin stdlib function that can be used in a nice way and fully compatible with Java's String format (it's only a wrapper around Java's String.format())

See Kotlin's documentation

Your code would be:

val pi = 3.14159265358979323
val s = "pi = %.2f".format(pi)

Since ECMA-/Javascript is all about Objects and Contexts (which, are also somekind of Object), every variable is stored in a such called Variable- (or in case of a Function, Activation Object).

So if you create variables like this:

var a = 1,
    b = 2,
    c = 3;

In the Global scope (= NO function context), you implicitly write those variables into the Global object (= window in a browser).

Those can get accessed by using the "dot" or "bracket" notation:

var name = window.a;

or

var name = window['a'];

This only works for the global object in this particular instance, because the Variable Object of the Global Object is the window object itself. Within the Context of a function, you don't have direct access to the Activation Object. For instance:

function foobar() {
   this.a = 1;
   this.b = 2;

   var name = window['a']; // === undefined
   alert(name);
   name = this['a']; // === 1
   alert(name);
}

new foobar();

new creates a new instance of a self-defined object (context). Without new the scope of the function would be also global (=window). This example would alert undefined and 1 respectively. If we would replace this.a = 1; this.b = 2 with:

var a = 1,
    b = 2;

Both alert outputs would be undefined. In that scenario, the variables a and b would get stored in the Activation Object from foobar, which we cannot access (of course we could access those directly by calling a and b).

Using JSON.stringify(data);:

$.ajax({
    url: ...
    success:function(data){
        JSON.stringify(data); //to string
        alert(data.you_value); //to view you pop up
    }
});

1. Go to EC2 Dashboard and click "Running Instances" on "Security Groups", select the group of your instance which you need to add security.
2. click on the "Inbound" tab
3. Click "Edit" Button (It will open an popup window)
4. click "Add Rule"
5. Select the "Custom ICMP rule - IPv4" as Type
6. Select "Echo Request" and "Echo Response" as the Protocol (Port Range by default show as "N/A)
7. Enter the "0.0.0.0/0" as Source
8. Click "Save"

Perhaps the shortest possible ways to evaluate an expression into "10" without digits are:

+!+[] + [+[]] // "10"

-~[] + [+[]] // "10"

//========== Explanation ==========\\

+!+[] : +[] Converts to 0. !0 converts to true. +true converts to 1. -~[] = -(-1) which is 1

[+[]] : +[] Converts to 0. [0] is an array with a single element 0.

Then JS evaluates the 1 + [0], thus Number + Array expression. Then the ECMA specification works: + operator converts both operands to a string by calling the toString()/valueOf() functions from the base Object prototype. It operates as an additive function if both operands of an expression are numbers only. The trick is that arrays easily convert their elements into a concatenated string representation.

Some examples:

1 + {} //    "1[object Object]"
1 + [] //    "1"
1 + new Date() //    "1Wed Jun 19 2013 12:13:25 GMT+0400 (Caucasus Standard Time)"

There's a nice exception that two Objects addition results in NaN:

[] + []   //    ""
[1] + [2] //    "12"
{} + {}   //    NaN
{a:1} + {b:2}     //    NaN
[1, {}] + [2, {}] //    "1,[object Object]2,[object Object]"

This code splits lines from text, and add everyone into a vector.

vector<string> split(char *phrase, string delimiter){
    vector<string> list;
    string s = string(phrase);
    size_t pos = 0;
    string token;
    while ((pos = s.find(delimiter)) != string::npos) {
        token = s.substr(0, pos);
        list.push_back(token);
        s.erase(0, pos + delimiter.length());
    }
    list.push_back(s);
    return list;
}

Called by:

vector<string> listFilesMax = split(buffer, "\n");

Use the code

x = seq(0,100,5) #this means (starting number, ending number, interval)

the output will be

Backbone was created by Jeremy Ashkenas who also wrote CoffeeScript. As a JavaScript-heavy application, what we now know as Backbone was responsible for structuring the application into a coherent code base. Underscore.js, backbone's only dependency, was also part of the DocumentCloud application.

Backbone helps developers manage a data model in their client-side web app with as much discipline and structure as you would get in traditional server-side application logic.

Additional benefits of using Backbone.js

1. See Backbone as a library, not as a framework
2. Javascript is now getting organized in a structured way, the (MVVM) Model
3. Large user community

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

It probably aimed to select all the informations in your table. If you use this kind of query (for example in PHP) :

mysql_query("SELECT * FROM newsletter WHERE email = '$email'");

The email ' OR 1=1/* will give this kind of query :

mysql_query("SELECT * FROM newsletter WHERE email = '' OR 1=1/*");

So it selects all the rows (because 1=1 is always true and the rest of the query is 'commented'). But it was not successful

• if strings used in your queries are escaped
• if you don't display all the queries results on a page...

If you are using Express, the cleanest complete answer is this

const express = require('express')
const app     = express()

app.get('*', (req, res) => {
  // REDIRECT goes here
  res.redirect('https://www.YOUR_URL.com/')
})

app.set('port', (process.env.PORT || 3000))
const server = app.listen(app.get('port'), () => {})

You can't, and you shouldn't. That's what polymorphism is for, so that each object has its own way of doing some "base" things.

The fancy new Java 8 way is Date.from(timestamp.toInstant()). See my similar answer elsewhere.

Put your assets in the public folder

public/css
public/images
public/fonts
public/js

And then called it using Laravel

{{ URL::asset('js/scrollTo.js'); }} // Generates the path to public directory public/js/scrollTo.js

{{ URL::asset('css/css.css'); }}   // Generates the  path to public directory public/css/css.css

(OR)

{{ HTML::script('js/scrollTo.js'); }} // Generates the  path to public directory public/js/scrollTo.js

{{ HTML::style('css/css.css'); }} // Generates the path to public directory public/css/css.css

The below code worked fine:

Run Keyword if    '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2'    LOG    HELLO

Similar to other answers, I wanted to ensure my ASP.NET Core 2.1 environment setting persisted across deployments, but also only applied to the specific site.

According to Microsoft's documentation, it is possible to set the environment variable on the app pool using the following PowerShell command in IIS 10:

$appPoolName = "AppPool"
$envName = "Development"
cd "$env:SystemRoot\system32\inetsrv"
.\appcmd.exe set config -section:system.applicationHost/applicationPools /+"[name='$appPoolName'].environmentVariables.[name='ASPNETCORE_ENVIRONMENT',value='$envName']" /commit:apphost

I unfortunately still have to use IIS 8.5 and thought I was out of luck. However, it is still possible to run a simple PowerShell script to set a site-specific environment variable value for ASPNETCORE_ENVIRONMENT:

Import-Module -Name WebAdministration
$siteName = "Site"
$envName = "Development"
Set-WebConfigurationProperty -PSPath IIS:\ -Location $siteName -Filter /system.webServer/aspNetCore/environmentVariables -Name . -Value @{ Name = 'ASPNETCORE_ENVIRONMENT'; Value = $envName }

uniq -u < file will do the job.

I'd like to point that something that i missed ...

I'm new at Laravel, and i didn't copy the "use Illuminate....." because i really didn'at paid atention, because right above the function boot you alread have a use Statement.

Hope that helps anyone

**use Illuminate\Support\Facades\Schema;**

public function boot()
{
    Schema::defaultStringLength(191);
}

I feel I want answer this question even there some good answers ,

according to documentation TransformationMethod do our mission

TransformationMethod

TextView uses TransformationMethods to do things like replacing the characters of passwords with dots, or keeping the newline characters from causing line breaks in single-line text fields.

Notice I use butter knife, but its the same if user check show password

@OnCheckedChanged(R.id.showpass)
    public void onChecked(boolean checked){
        if(checked){
            et_password.setTransformationMethod(null);
        }else {
            et_password.setTransformationMethod(new PasswordTransformationMethod());
            
        }
       // cursor reset his position so we need set position to the end of text
        et_password.setSelection(et_password.getText().length());
    }

I recommend not to use one of those methods as is. Write your own function which does the right thing.

MDN has given a good example on url encoding shown below.

var fileName = 'my file(2).txt';
var header = "Content-Disposition: attachment; filename*=UTF-8''" + encodeRFC5987ValueChars(fileName);

console.log(header); 
// logs "Content-Disposition: attachment; filename*=UTF-8''my%20file%282%29.txt"


function encodeRFC5987ValueChars (str) {
    return encodeURIComponent(str).
        // Note that although RFC3986 reserves "!", RFC5987 does not,
        // so we do not need to escape it
        replace(/['()]/g, escape). // i.e., %27 %28 %29
        replace(/\*/g, '%2A').
            // The following are not required for percent-encoding per RFC5987, 
            //  so we can allow for a little better readability over the wire: |`^
            replace(/%(?:7C|60|5E)/g, unescape);
}

I had this confusion for a while and I'm trying my best to provide a simple explanation here. Hope this will help!

angular .factory and angular .service both are used to initialize a service and work in the same way.

The only difference is, how you want to initialize your service.

Both are Singletons

var app = angular.module('app', []);

Factory

app.factory(<service name>, <function with a return value>)

If you would like to initialize your service from a function that you have with a return value, you have to use this factory method.

e.g.

function myService() {
  //return what you want
  var service = {
    myfunc: function (param) { /* do stuff */ }
  }
  return service;
}

app.factory('myService', myService);

When injecting this service (e.g. to your controller):

• Angular will call your given function (as myService()) to return the object
• Singleton - called only once, stored, and pass the same object.

Service

app.service(<service name>, <constructor function>)

If you would like to initialize your service from a constructor function (using this keyword), you have to use this service method.

e.g.

function myService() {
  this.myfunc: function (param) { /* do stuff */ }
}

app.service('myService', myService);

When injecting this service (e.g. to your controller):

• Angular will newing your given function (as new myService()) to return the object
• Singleton - called only once, stored, and pass the same object.

Examples - DEMOs

• Angular Service vs Factory
• Angular Service vs Factory (with route)

Approch 1

First get the commit hash(ex:1406cd61) that you need to revert. simple fix will be below command,

$ git revert 1406cd61

if you have commit more changes related to 1406cd61 files after 1406cd61 commit, Above simple command will not work. Then you have to do the below steps, which is cherry picking.

Approch 2

Please follow below squesnce of actions, Since we are using --force you need to have admin rights over the git repo to do this.

Step 1: Find the commit before the commit you want to remove git log

Step 2: Checkout that commit git checkout <commit hash>

Step 3: Make a new branch using your current checkout commit git checkout -b <new branch>

Step 4: Now you need to add the commit after the removed commit git cherry-pick <commit hash>

Step 5: Now repeat Step 4 for all other commits you want to keep.

Step 6: Once all commits have been added to your new branch and have been commited. Check that everything is in the correct state and working as intended. Double check everything has been commited: git status

Step 7: Switch to your broken branch git checkout <broken branch>

Step 8: Now perform a hard reset on the broken branch to the commit prior to the one your want to remove git reset --hard <commit hash>

Step 9: Merge your fixed branch into this branch git merge <branch name>

Step 10: Push the merged changes back to origin. WARNING: This will overwrite the remote repo! git push --force origin <branch name>

You can do the process without creating a new branch by replacing Step 2 & 3 with Step 8 then not carry out Step 7 & 9.

The code example is exactly this:

from xlutils.copy import copy
from xlrd import *
w = copy(open_workbook('book1.xls'))
w.get_sheet(0).write(0,0,"foo")
w.save('book2.xls')

You'll need to create book1.xls to test, but you get the idea.

As well as @Pablo's answer, for newer versions you can also use the asp-page-handler tag helper.

In the page:

<button asp-page-handler="Action1" type="submit">Action 1</button>
<button asp-page-handler="Action2" type="submit">Action 2</button>

then in the controller:

    public async Task OnPostAction1Async() {...}
    public async Task OnPostAction2Async() {...}

If you are using JetBrains editors like IntelliJ IDEA, PhpStorm, WebStorm etc. Use the following settings in Settings > File Watchers.

1. Convert style.scss to style.css set the arguments

   --no-cache --update $FileName$:$FileNameWithoutExtension$.css
   

   and output paths to refresh

   $FileNameWithoutExtension$.css
   

2. Convert style.scss to compressed style.min.css set the arguments

   --no-cache --update $FileName$:$FileNameWithoutExtension$.min.css --style compressed
   

   and output paths to refresh

   $FileNameWithoutExtension$.min.css
   

You can also get this error message on its own, without any stack trace or any further error message.

In this case you need to make sure your Android manifest is configured correctly (including any manifest merging happening from a library and any activity that would come from a library), and pay particular attention to the first activity displayed in your application in your manifest files.

This is off the cuff, but isn't that what Grasshopper was for?

Solving this problem is simple. All I did was to add "SelectedValuePath" to my XAML code and bind it to my model property that I want to return with the combobox.

<ComboBox SelectedValuePath="_Department"
          DisplayMemberPath="_Department"
          Height="23"
          HorizontalAlignment="Left"
          ItemsSource="{Binding}"
          Margin="-58,1,0,5"
          Name="_DepartmentComboBox"
          VerticalAlignment="Center"
          Width="268"/>

.outside {
    width: 200px;
    height: 200px;
    background-color: #EEE; /*to make it visible*/
}

Needs to be

.outside {
    position: relative;
    width: 200px;
    height: 200px;
    background-color: #EEE; /*to make it visible*/
}

Absolute positioning looks for the nearest relatively positioned parent within the DOM, if one isn't defined it will use the body.

None of the above answers were generic enough for me so I made this one:

var someUserInputStringValue = "propertyNameOfObject i.e. 'Quantity' or 'Date'";
var SortedData = DataToBeSorted
                   .OrderBy(m => m.GetType()
                                  .GetProperties()
                                  .First(n => 
                                      n.Name == someUserInputStringValue)
                   .GetValue(m, null))
                 .ToList();

Careful on massive data sets though. It's easy code but could get you in trouble if the collection is huge and the object type of the collection has a large number of fields. Run time is NxM where:

N = # of Elements in collection

M = # of Properties within Object

You need the following permissions in your manifest file:

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

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

Primitives are a different kind of type than objects created from within Javascript. From the Mozilla API docs:

var color1 = new String("green");
color1 instanceof String; // returns true
var color2 = "coral";
color2 instanceof String; // returns false (color2 is not a String object)

I can't find any way to construct primitive types with code, perhaps it's not possible. This is probably why people use typeof "foo" === "string" instead of instanceof.

An easy way to remember things like this is asking yourself "I wonder what would be sane and easy to learn"? Whatever the answer is, Javascript does the other thing.

You are not initializing your String[]. You either need to initialize it using the exact array size, as suggested by @Tr?nSiLong, or use a List<String> and then convert to a String[] (in case you do not know the length):

String[] title = {
        "Abundance",
        "Anxiety",
        "Bruxism",
        "Discipline",
        "Drug Addiction"
    };
String urlbase = "http://www.somewhere.com/data/";
String imgSel = "/logo.png";
List<String> mStrings = new ArrayList<String>();

for(int i=0;i<title.length;i++) {
    mStrings.add(urlbase + title[i].toLowerCase() + imgSel);

    System.out.println(mStrings[i]);
}

String[] strings = new String[mStrings.size()];
strings = mStrings.toArray(strings);//now strings is the resulting array

This looks confusing because you are taking long as a datatype itself.

long is nothing but just the shorthand for long int when you are using it alone.

long is a modifier, you can use it with double also as long double.

long == long int.

Both of them take 4 bytes.

Hi it is also possible for Strings with XML-Table

SELECT trim(COLUMN_VALUE) str FROM xmltable(('"'||REPLACE('a1, b2, a2, c1', ',', '","')||'"'));

As of 2015, it now just works.

<input type="file">

This will ask user for the upload of any file. On iOS 8.x this can be a camera video, camera photo, or a photo/video from Photo Library.

<input type="file" accept="image/*">

This is as above, but limits the uploads to photos only from camera or library, no videos.

If the previous answers do not solve your problem, check the source of the data that won't print/convert properly.

In my case, I was using json.load on data incorrectly read from file by not using the encoding="utf-8". Trying to de-/encode the resulting string to latin-1 just does not help...

Looking at the output of free -m it seems to me that you actually do not have swap memory available. I am not sure if in Linux the swap always will be available automatically on demand, but I was having the same problem and none of the answers here really helped me. Adding some swap memory however, fixed the problem in my case so since this might help other people facing the same problem, I post my answer on how to add a 1GB swap (on Ubuntu 12.04 but it should work similarly for other distributions.)

You can first check if there is any swap memory enabled.

$sudo swapon -s

if it is empty, it means you don't have any swap enabled. To add a 1GB swap:

$sudo dd if=/dev/zero of=/swapfile bs=1024 count=1024k
$sudo mkswap /swapfile
$sudo swapon /swapfile

Add the following line to the fstab to make the swap permanent.

$sudo vim /etc/fstab

     /swapfile       none    swap    sw      0       0 

Source and more information can be found here.

When you run into a problem where it cats all.txt into all.txt, You can try check all.txt is existing or not, if exists, remove

Like this:

[ -e $"all.txt" ] && rm $"all.txt"

The issue behind this error is Unavailability of App ID with given Bundle Identifier

Solution: Change Bundle Identifier simple :)

There are a handful of options:

• NPOI - Which is free and open source.
• Aspose - Is definitely not free but robust.
• Spreadsheet ML - Basically XML for creating spreadsheets.

Using the Interop will require that the Excel be installed on the machine from which it is running. In a server side solution, this will be awful. Instead, you should use a tool like the ones above that lets you build an Excel file without Excel being installed.

If the user does not have Excel but has a tool that will read Excel (like Open Office), then obviously they will be able to open it. Microsoft has a free Excel viewer available for those users that do not have Excel.

If you are using Kotlin than use like this

For Decode

val datasd = Base64.decode(base64, Base64.DEFAULT)
val text = String(datasd, charset("UTF-8"))

First add next code in your sp:

BEGIN
    dbms_output.enable();
    dbms_output.put_line ('TEST LINE'); 
END;

Compile your code in your Oracle SQL developer. So go to Menu View--> dbms output. Click on Icon Green Plus and select your schema. Run your sp now.

select
  Field1, Field2...
from
  Table1
order by
  isnumeric(Field1) desc,
  case when isnumeric(Field1) = 1 then cast(Field1 as int) else null end,
  Field1

This will return values in the order you gave in your question.

Performance won't be too great with all that casting going on, so another approach is to add another column to the table in which you store an integer copy of the data and then sort by that first and then the column in question. This will obviously require some changes to the logic that inserts or updates data in the table, to populate both columns. Either that, or put a trigger on the table to populate the second column whenever data is inserted or updated.

Just add margin: 0 auto; to the inside div.

GregorianCalendar c = GregorianCalendar.from((LocalDate.parse("2016-06-22")).atStartOfDay(ZoneId.systemDefault()));
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

after creating the view we have to add layout parameters .

change like this

TextView tv = new TextView(this);
tv.setLayoutParams(new ViewGroup.LayoutParams(
        ViewGroup.LayoutParams.WRAP_CONTENT,
        ViewGroup.LayoutParams.WRAP_CONTENT));

llview.addView(tv);
tv.setTextColor(Color.WHITE);
tv.setTextSize(2,25);
tv.setText(chat);
if (mine) {
    leftMargin = 5;
    tv.setBackgroundColor(0x7C5B77);
}
else {
    leftMargin = 50;
    tv.setBackgroundColor(0x778F6E);
}
final ViewGroup.MarginLayoutParams lpt =(MarginLayoutParams)tv.getLayoutParams();
lpt.setMargins(leftMargin,lpt.topMargin,lpt.rightMargin,lpt.bottomMargin);

Thankfully, it's not possible to change the duration of the vibration. The only way to trigger the vibration is to play the kSystemSoundID_Vibrate as you have. If you really want to though, what you can do is to repeat the vibration indefinitely, resulting in a pulsing vibration effect instead of a long continuous one. To do this, you need to register a callback function that will get called when the vibration sound that you play is complete:

 AudioServicesAddSystemSoundCompletion (
        kSystemSoundID_Vibrate,
        NULL,
        NULL,
        MyAudioServicesSystemSoundCompletionProc,
        NULL
    );
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

Then you define your callback function to replay the vibrate sound again:

#pragma mark AudioService callback function prototypes
void MyAudioServicesSystemSoundCompletionProc (
   SystemSoundID  ssID,
   void           *clientData
);

#pragma mark AudioService callback function implementation

// Callback that gets called after we finish buzzing, so we 
// can buzz a second time.
void MyAudioServicesSystemSoundCompletionProc (
   SystemSoundID  ssID,
   void           *clientData
) {
  if (iShouldKeepBuzzing) { // Your logic here...
      AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); 
  } else {
      //Unregister, so we don't get called again...
      AudioServicesRemoveSystemSoundCompletion(kSystemSoundID_Vibrate);
  }  
}

My self-made solution which is easy to edit:

HTML:

<div id="anti-shadow-div">
    <div id="shadow-div"></div>
</div>?

css:

#shadow-div{
    margin-right:20px; /* Set to 0 if you don't want shadow at the right side */

I'm just beginning to use JPype 0.5.4.2 (july 2011) and it looks like it's working nicely...
I'm on Xubuntu 10.04

Hmmm... I suppose the closest thing to an enum would be a dictionary, defined either like this:

months = {
    'January': 1,
    'February': 2,
    ...
}

or

months = dict(
    January=1,
    February=2,
    ...
)

Then, you can use the symbolic name for the constants like this:

mymonth = months['January']

There are other options, like a list of tuples, or a tuple of tuples, but the dictionary is the only one that provides you with a "symbolic" (constant string) way to access the value.

Edit: I like Alexandru's answer too!

You can create a helper method that accept a one object parameter base on error arguments

 error(message: string, title?: string, autoHideAfter?: number){}

 getError(args: { message: string, title?: string, autoHideAfter?: number }) {
    return error(args.message, args.title, args.autoHideAfter);
 }

This answer is based on answer https://stackoverflow.com/a/24933495/3890888 but with a plain JavaScript version of the script used there.

You need to make the SVG to be an inline SVG. You can make use of this script, by adding a class svg to the image:

/*
 * Replace all SVG images with inline SVG
 */
document.querySelectorAll('img.svg').forEach(function(img){
    var imgID = img.id;
    var imgClass = img.className;
    var imgURL = img.src;

    fetch(imgURL).then(function(response) {
        return response.text();
    }).then(function(text){

        var parser = new DOMParser();
        var xmlDoc = parser.parseFromString(text, "text/xml");

        // Get the SVG tag, ignore the rest
        var svg = xmlDoc.getElementsByTagName('svg')[0];

        // Add replaced image's ID to the new SVG
        if(typeof imgID !== 'undefined') {
            svg.setAttribute('id', imgID);
        }
        // Add replaced image's classes to the new SVG
        if(typeof imgClass !== 'undefined') {
            svg.setAttribute('class', imgClass+' replaced-svg');
        }

        // Remove any invalid XML tags as per http://validator.w3.org
        svg.removeAttribute('xmlns:a');

        // Check if the viewport is set, if the viewport is not set the SVG wont't scale.
        if(!svg.getAttribute('viewBox') && svg.getAttribute('height') && svg.getAttribute('width')) {
            svg.setAttribute('viewBox', '0 0 ' + svg.getAttribute('height') + ' ' + svg.getAttribute('width'))
        }

        // Replace image with new SVG
        img.parentNode.replaceChild(svg, img);

    });

});

And then, now if you do:

.logo-img path {
  fill: #000;
}

Or may be:

.logo-img path {
  background-color: #000;
}

I solved this by using the DropDownClosed event because this fires slightly after the value is changed.

PHPMYADMIN - Cannot connect: invalid settings.

I also faced similar issue but now I found a fix.

For wamp server:

IN: C:\wamp\apps\phpmyadminVERSION\config.inc.php

$cfg['Servers'][$i]['AllowNoPasswordRoot'] = true; 

$cfg['Servers'][$i]['AllowNoPasswordRoot'] = false; 

For xampp server:

because of xampp server had the following settings.

C:\xampp\phpMyAdmin\config.inc.php

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = ''; // which is default setting in xampp server

$cfg['Servers'][$i]['password'] = 'your password';//type your password you have changed

In the select where you want your concatenation, call a SQL function.

For example:

select PID, dbo.MyConcat(PID)
   from TableA;

Then for the SQL function:

Function MyConcat(@PID varchar(10))
returns varchar(1000)
as
begin

declare @x varchar(1000);

select @x = isnull(@x +',', @x, @x +',') + Desc
  from TableB
    where PID = @PID;

return @x;

end

The Function Header syntax might be wrong, but the principle does work.

You can do something like,

RaisedButton.icon( elevation: 4.0,
                    icon: Image.asset('images/image_upload.png' ,width: 20,height: 20,) ,
                      color: Theme.of(context).primaryColor,
                    onPressed: getImage,
                    label: Text("Add Team Image",style: TextStyle(
                        color: Colors.white, fontSize: 16.0))
                  ),

It's as simple as:

>>> lists = [[1, 2], [3, 4]]
>>> np.array(lists)
array([[1, 2],
       [3, 4]])

<a href="#">Start of page</a>

"The link has the href value of "#", which by definition means the start of the current document. Thus there is no need to worry about the correct way of setting up the destination anchor..."

To Increase request time out add this to web.config

<system.web>
    <httpRuntime executionTimeout="180" />
</system.web>

and for a specific page add this

<location path="somefile.aspx">
    <system.web>
        <httpRuntime executionTimeout="180"/>
    </system.web>
</location>

The default is 90 seconds for .NET 1.x.

The default 110 seconds for .NET 2.0 and later.

You can get the name of the city, country, street name and other geodata using the Google Maps Geocoding API

You don't need to reinstall MySQL server I was facing the same issue but I have resolved the issue by running these commands.

1. ps -A|grep mysql
2. sudo pkill mysql
3. ps -A|grep mysqld
4. sudo pkill mysqld
5. sudo service mysql restart
6. mysql -u root -p

Add the following CSS;

.modal .modal-dialog .modal-content{  background-color: #d4c484; }

<div class="modal fade">
<div class="modal-dialog" role="document">
<div class="modal-content">
...
...

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

I think it's a little simpler to use the dplyr functions select and left_join ; at least it's easier for me to understand. The join function from dplyr are made to mimic sql arguments.

 library(tidyverse)

 DF2 <- DF2 %>%
   select(client, LO)

 joined_data <- left_join(DF1, DF2, by = "Client")

You don't actually need to use the "by" argument in this case because the columns have the same name.

You can use this script. http://pellepim.bitbucket.org/jstz/

Fork or clone repository here. https://bitbucket.org/pellepim/jstimezonedetect

Once you include the script, you can get the list of timezones in - jstz.olson.timezones variable.

And following code is used to determine client browser's timezone.

var tz = jstz.determine();
tz.name();

Enjoy jstz!

function function_one() {
  function_two(); 
}

function function_two() {
//enter code here
}

I was facing this issue and fixed by putting a check in form attribute. This issue can happen when the FormGroup is not initialized.

<form [formGroup]="loginForm" *ngIf="loginForm">
OR
<form [formGroup]="loginForm" *ngIf="this.loginForm">

This will not render the form until it is initialized.
