I think the issue is with binding:
constructor(props){
super(props);
this.goBack = this.goBack.bind(this); // i think you are missing this
}
goBack(){
this.props.history.goBack();
}
.....
<button onClick={this.goBack}>Go Back</button>
As I have assumed before you posted the code:
constructor(props) {
super(props);
this.handleNext = this.handleNext.bind(this);
this.handleBack = this.handleBack.bind(this); // you are missing this line
}

Why not use an input-group?
<div class="input-group col-md-4">
<input class="form-control py-2" type="search" value="search" id="example-search-input">
<span class="input-group-append">
<button class="btn btn-outline-secondary" type="button">
<i class="fa fa-search"></i>
</button>
</span>
</div>
And, you can make it appear inside the input using the border utils...
<div class="input-group col-md-4">
<input class="form-control py-2 border-right-0 border" type="search" value="search" id="example-search-input">
<span class="input-group-append">
<button class="btn btn-outline-secondary border-left-0 border" type="button">
<i class="fa fa-search"></i>
</button>
</span>
</div>
Or, using a input-group-text
w/o the gray background so the icon appears inside the input...
<div class="input-group">
<input class="form-control py-2 border-right-0 border" type="search" value="search" id="example-search-input">
<span class="input-group-append">
<div class="input-group-text bg-transparent"><i class="fa fa-search"></i></div>
</span>
</div>
Alternately, you can use the grid (row
>col-
) with no gutter spacing:
<div class="row no-gutters">
<div class="col">
<input class="form-control border-secondary border-right-0 rounded-0" type="search" value="search" id="example-search-input4">
</div>
<div class="col-auto">
<button class="btn btn-outline-secondary border-left-0 rounded-0 rounded-right" type="button">
<i class="fa fa-search"></i>
</button>
</div>
</div>
Or, prepend the icon like this...
<div class="input-group">
<span class="input-group-prepend">
<div class="input-group-text bg-transparent border-right-0">
<i class="fa fa-search"></i>
</div>
</span>
<input class="form-control py-2 border-left-0 border" type="search" value="..." id="example-search-input" />
<span class="input-group-append">
<button class="btn btn-outline-secondary border-left-0 border" type="button">
Search
</button>
</span>
</div>

To get rid of the bad looking datepicker you need to add jquery-ui css
<link rel="stylesheet" type="text/css" href="https://code.jquery.com/ui/1.12.0/themes/smoothness/jquery-ui.css">
Looks like the path you gave doesn't have any bootstrap files in them.
href="~/lib/bootstrap/dist/css/bootstrap.min.css"
Make sure the files exist over there , else point the files to the correct path, which should be in your case
href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

If you want a responsive card-deck, use the visibility utils to force a wrap every X columns on different viewport width(breakpoints)...
Bootstrap 4 responsive card-deck (v 4.1)
Original answer for Bootstrap 4 alpha 2:
You can use the grid col-*-*
to get the different widths (instead of card-deck) and then set equal height to the cols using flexbox.
.row > div[class*='col-'] {
display: flex;
flex:1 0 auto;
}
http://codeply.com/go/O0KdSG2YX2 (alpha 2)
The problem is that w/o flexbox enabled the card-deck
uses table-cell
where it becomes very hard to control the width. As of Bootstrap 4 Alpha 6, flexbox is default so the additional CSS is not required for flexbox, and the h-100
class can be used to make the cards full height: http://www.codeply.com/go/gnOzxd4Spk

give id to submit button
<button id="btnSave" type="submit" class="btn btn-success"><i class="glyphicon glyphicon-trash"></i> Save</button>
$('#btnSave').click(function() {
$('#StudentModal').modal('hide');
});
Also you forgot to close last div.
</div>
Hope this helps.
The problem is that you have not included bootstrap.min.css
. Also, the sequence of imports could be causing issue. Please try rearranging your resources as following:
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/css/bootstrap-datetimepicker.min.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.6/moment.min.js"></script>

Overview:
I am using bootstrap 4 without glyphicons. I found a problem with bootstrap treeview that depends upon glyphicons. I am using treeview as is, and I am using scss @extend to translate the icon class styles to font awesome class styles. I think this is quite slick (if you ask me)!
Details:
I used scss @extend to handle it for me.
I previously decided to use font-awesome for no better reason than I have used it in the past.
When I went to try bootstrap treeview, I found that the icons were missing, because I didn't have glyphicons installed.
I decided to use the scss @extend feature, to have the glyphicon classes use the font-awesome classes as so:
.treeview {
.glyphicon {
@extend .fa;
}
.glyphicon-minus {
@extend .fa-minus;
}
.glyphicon-plus {
@extend .fa-plus;
}
}
I tried all the suggestions above, but my actual issue was that my application was looking for the /font folder and its contents (.woff etc) in app/fonts, but my /fonts folder was on the same level as /app. I moved /fonts under /app, and it works fine now. I hope this helps someone else roaming the web for an answer.
I'm using a simplyfied version (just using position relative) based on @SimonEast answer:
li:before {
content: "\e080";
font-family: 'Glyphicons Halflings';
font-size: 9px;
position: relative;
margin-right: 10px;
top: 3px;
color: #ccc;
}
You guys copied the wrong code.
Go into the "/build" folder and grab the jquery.datetimepicker.full.js or jquery.datetimepicker.full.min.js if you want the minified version. It should fix it! :)
Reactstrap also has an implementation of Bootstrap Modals in React. This library targets Bootstrap version 4, whereas react-bootstrap targets version 3.X.
If you want use margin, remove the class on every button and use :last-child CSS selector.
Html :
<div class="btn-toolbar text-center well">
<button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
<span class="glyphicon glyphicon-plus" aria-hidden="true"></span> ADD PACKET
</button>
<button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
<span class="glyphicon glyphicon-edit" aria-hidden="true"></span> EDIT CUSTOMER
</button>
<button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
<span class="glyphicon glyphicon-time" aria-hidden="true"></span> HISTORY
</button>
<button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
<span class="glyphicon glyphicon-trash" aria-hidden="true"></span> DELETE CUSTOMER
</button>
</div>
Css :
.btn-toolbar .btn{
margin-right: 5px;
}
.btn-toolbar .btn:last-child{
margin-right: 0;
}
You can go through the below code to solve this.
$(document).on('click.bs.dropdown.data-api', '.keep_it_open', function (e) {_x000D_
e.stopPropagation();_x000D_
});

Fontawesome has a perfect solution to this.
I implemented the same. just on your main .css file add this
.gi-2x{font-size: 2em;}
.gi-3x{font-size: 3em;}
.gi-4x{font-size: 4em;}
.gi-5x{font-size: 5em;}
In your example you just have to do this.
<div class = "jumbotron">
<span class="glyphicon glyphicon-globe gi-5x"></span>
</div>
You can do it in pure CSS using the :after pseudo-element and getting creative with the margins.
Here's an example, using Font Awesome for the search icon:
.search-box-container input {_x000D_
padding: 5px 20px 5px 5px;_x000D_
}_x000D_
_x000D_
.search-box-container:after {_x000D_
content: "\f002";_x000D_
font-family: FontAwesome;_x000D_
margin-left: -25px;_x000D_
margin-right: 25px;_x000D_
}
_x000D_
<!-- font awesome -->_x000D_
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
_x000D_
_x000D_
<div class="search-box-container">_x000D_
<input type="text" placeholder="Search..." />_x000D_
</div>
_x000D_
For changing the text color in navbar you can use inline css as;
<a style="color: #3c6afc" href="#">
With so many answers already written, Here's my take.
With Angular 1.5.6 & ui-bootstrap 1.3.3 , just add this on the model & you are done.
ng-model-options="{timezone: 'UTC'}"
Note: Use this only if you are concerned about the date being 1 day behind & not bothered with extra time of T00:00:00.000Z
Updated Plunkr Here :
Changing to format: 'dd/mm/yyyy'
didn't work for me, and changing that to dateFormat: 'dd/mm/yyyy'
added year multiple times, The finest one for me was,
dateFormat: 'dd/mm/yy'
Now Update word-wrap is replace by :
overflow-wrap:break-word;
Compatible old navigator and css 3 it's good alternative !
it's evolution of word-wrap ( since 2012... )
See more information : https://www.w3.org/TR/css-text-3/#overflow-wrap
See compatibility full : http://caniuse.com/#search=overflow-wrap
Consider also .attr()
$("#roommate_but").attr("disabled", true);
worked for me.
You don't need to go level up and use ..
since all buttons are on the same level:
//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']
This works for me:
CSS
.form-group.required.control-label:before{
content: "*";
color: red;
}
OR
.form-group.required.control-label:after{
content: "*";
color: red;
}
Basic HTML
<div class="form-group required control-label">
<input class="form-control" />
</div>
I don't understand why the other friends tell you use HH
, But after I test so many time, The correct 24 hour format is :
hh
.
I see it from : http://www.malot.fr/bootstrap-datetimepicker/
I don't know why they don't use the common type HH
for 24 hour.....
I hope anyone could tell me if I'm wrong.....
I needed to add this functionality to a project I was working on recently and adding jQuery Mobile just to solve this problem seemed like overkill, so I came up with a solution and put it on github: bcSwipe (Bootstrap Carousel Swipe).
It's a lightweight jQuery plugin (~600 bytes minified vs jQuery Mobile touch events at 8kb), and it's been tested on Android and iOS.
This is how you use it:
$('.carousel').bcSwipe({ threshold: 50 });
In case it might help someone, I had a similar issue after adding Bootstrap 3 to my MVC 4 project. It turned out my problem was that I was referring to bootstrap-min.js instead of bootstrap.js in my BundleConfig.cs.
Didn't work:
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap-min.js"));
Worked:
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js"));
For me, the carousel wasn't working in the DreamWeaver CC provided the code in the "template" page I am playing with. I needed to add the data-ride="carousel" attribute to the carousel div in order for it to start working. Thanks to Adarsh for his code snippet which highlighted the missing attribute.
type=submit
it is a Submit Button type=button
it is just a button, It does not submit your form inputs. and also you don't want to use both of these
Try this:
$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(40);
We can find these by looking at Bootstrap's stylesheet, Bootstrap.css. Each \{number}
represents a hexadecimal value, so \2a
is equal to 0x2a
or *
.
As for the font, that can be downloaded from http://glyphicons.com.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.
Bootstrap requires a specific file structure to work. I see from your code you have this:
<link href="bootstrap.css" rel="stylesheet" media="screen">
Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.
But first, let me recommend you setup your folder structure like so:
/css <-- Bootstrap.css here
/fonts <-- Bootstrap fonts here
/img
/js <-- Bootstrap JavaScript here
index.html
If you notice, this is also how Bootstrap structures its files in its download ZIP.
You then include your Bootstrap file like so:
<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">
Depending on your server structure or what you're going for.
The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).
The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.
So, why do this?
Bootstrap.css has this specific line for Glyphfonts:
@font-face {
font-family: 'Glyphicons Halflings';
src: url('../fonts/glyphicons-halflings-regular.eot');
src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
What you can see is that that Glyphfonts are loaded by going up one directory ../
and then looking for a folder called /fonts
and THEN loading the font file.
The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:
/fonts
Bootstrap.css
index.html
The CSS file is going one level deeper than looking for a /fonts
folder.
So, let's say the actual location of these files are:
C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html
The CSS file would technically be looking for a folder at:
C:\fonts
but your folder is actually in:
C:\www\fonts
So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.
When you get that fixed, your HTML should simply be:
<span class="glyphicon glyphicon-comment"></span>
Note, you need both classes. The first class glyphicon
sets up the basic styles while glyphicon-comment
sets the specific image.
Via Angular: using ng-class
of Angular, we can hide and show the side bar.
http://jsfiddle.net/DVE4f/359/
<div class="container" style="width:100%" ng-app ng-controller="AppCtrl">
<div class="row">
<div ng-class="showgraphSidebar ? 'col-xs-3' : 'hidden'" id="colPush" >
Sidebar
</div>
<div ng-class="showgraphSidebar ? 'col-xs-9' : 'col-xs-12'" id="colMain" >
<button ng-click='toggle()' >Sidebar Toggle</a>
</div>
</div>
</div>
.
function AppCtrl($scope) {
$scope.showgraphSidebar = false;
$scope.toggle = function() {
$scope.showgraphSidebar = !$scope.showgraphSidebar;
}
}
I ended up using the bootstrap 3 dropdown button, I'm posting my solution here in case it helps someone in future. Adding the bootstrap 3 list-inline to the class for the ul causes it to display in a nicely compact format as well.
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Select icon <span class="caret"></span>
</button>
<ul class="dropdown-menu list-inline" role="menu">
<li><span class="glyphicon glyphicon-cutlery"></span></li>
<li><span class="glyphicon glyphicon-fire"></span></li>
<li><span class="glyphicon glyphicon-glass"></span></li>
<li><span class="glyphicon glyphicon-heart"></span></li>
</ul>
</div>
I'm using Angular.js so this is the actual code I used:
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Avatar <span class="caret"></span>
</button>
<ul class="dropdown-menu list-inline" role="menu">
<li ng-repeat="avatar in avatars" ng-click="avatarSelected(avatar)">
<span ng-class="getAvatar(avatar)"></span>
</li>
</ul>
</div>
And in my controller:
$scope.avatars=['cutlery','eye-open','flag','flash','glass','fire','hand-right','heart','heart-empty','leaf','music','send','star','star-empty','tint','tower','tree-conifer','tree-deciduous','usd','user','wrench','time','road','cloud'];
$scope.getAvatar=function(avatar){
return 'glyphicon glyphicon-'+avatar;
};
Maybe it's the comma in your if
condition.
function answers() {
var answer=document.getElementById("mySelect");
if(answer[answer.selectedIndex].value == "To measure time.") {
alert("That's correct!");
}
}
You can also write it like this.
function answers(){
document.getElementById("mySelect").value!="To measure time."||(alert('That's correct!'))
}
Here is how I did it using only the default bootstrap CSS v3.3.1:
<div class="form-group">
<label class="control-label">Start:</label>
<div class="input-group">
<input type="text" class="form-control" aria-describedby="start-date">
<span class="input-group-addon" id="start-date"><span class="glyphicon glyphicon-calendar"></span></span>
</div>
</div>
And this is how it looks:
Check this out : http://codepen.io/Rowno/pen/Afykb
.carousel-fade {
.carousel-inner {
.item {
opacity: 0;
transition-property: opacity;
}
.active {
opacity: 1;
}
.active.left,
.active.right {
left: 0;
opacity: 0;
z-index: 1;
}
.next.left,
.prev.right {
opacity: 1;
}
}
Works marvellously, I hope it works
just simple:
.navbar{
width:65% !important;
margin:0px auto;
left:0;
right:0;
padding:0;
}
or,
.navbar.navbar-fixed-top{
width:65% !important;
margin:0px auto;
left:0;
right:0;
padding:0;
}
Hope it works (at least, for future searchers)
<button class="btn btn-default glyphicon glyphicon-plus fa-2x" type="button">_x000D_
</button>_x000D_
_x000D_
<!--fa-2x , fa-3x , fa-4x ... -->_x000D_
<button class="btn btn-default glyphicon glyphicon-plus fa-3x" type="button">_x000D_
</button>
_x000D_
As @Stijn described, the default location in Bootstrap.css
is incorrect when installing this package from Nuget
.
Change this section to look like this:
@font-face {
font-family: 'Glyphicons Halflings';
src: url('Content/fonts/glyphicons-halflings-regular.eot');
src: url('Content/fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded- opentype'), url('Content/fonts/glyphicons-halflings-regular.woff') format('woff'), url('Content/fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('Content/fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
CSS:
.blue-icon{
color:blue !important;
}
HTML
<i class="fa fa-wrench blue-icon"></i>
Glyphicons are removed in 4.0, i recommend Font-awesome 4 or newer :)
Here's a couple of pure css helper classes which lets you handle any kind of toggle content right in your html.
It works with any element you need to switch. Whatever your layout is you just put it inside a couple of elements with the .if-collapsed and .if-not-collapsed classes within the toggle element.
The only catch is that you have to make sure you put the desired initial state of the toggle. If it's initially closed, then put a collapsed class on the toggle.
It also requires the :not selector, it doesn't work on IE8.
HTML example:
<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
<!--You can put any valid html inside these!-->
<span class="if-collapsed">Open</span>
<span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
<div class="well">
...
</div>
</div>
Less version:
[data-toggle="collapse"] {
&.collapsed .if-not-collapsed {
display: none;
}
&:not(.collapsed) .if-collapsed {
display: none;
}
}
CSS version:
[data-toggle="collapse"].collapsed .if-not-collapsed {
display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
display: none;
}
For me placing my fonts folder as per location specified in bootstrap.css solved the problem
Mostly its fonts folder should be in parent directory of bootstrap.css file .
I faced this problem , and researching many answers , if anyone still in 2015 faces this problem then its either a CSS problem , or location mismatch for files .
The bug has already been solved by bootstrap
Although Bootstrap CDN restored glyphicons to bootstrap.min.css, Bootstrap CDN's Bootswatch css files doesn't include glyphicons.
For example Amelia theme: http://bootswatch.com/amelia/
Default Amelia has glyphicons in this file: http://bootswatch.com/amelia/bootstrap.min.css
But Bootstrap CDN's css file doesn't include glyphicons: http://netdna.bootstrapcdn.com/bootswatch/3.0.0/amelia/bootstrap.min.css
So as @edsioufi mentioned, you should include you should include glphicons css, if you use Bootswatch files from the bootstrap CDN. File: http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css
There you go:
<i class="glyphicon glyphicon-search"></i>
More information:
http://getbootstrap.com/components/#glyphicons
Btw. you can use this conversion tool, this will also update the code for the icons:
You can just create your own .white
class and add it to the glyphicon element.
.white, .white a {
color: #fff;
}
<i class="glyphicon glyphicon-home white"></i>
Try passing it directly to the ng-click function:
<div class="col-lg-1 text-center">
<span class="glyphicon glyphicon-trash" data="{{event.id}}"
ng-click="deleteEvent(event.id)"></span>
</div>
Then it should be available in your handler:
$scope.deleteEvent=function(idPassedFromNgClick){
console.log(idPassedFromNgClick);
}
Here's an example
Since the glyphicons image is a sprite, you really can't do that: fundamentally what you want is to limit the size of the background, but there's no way to specify how big the background is. Either you cut out the icon you want, size it down and use it, or use something like the input field prepend/append option (http://twitter.github.io/bootstrap/base-css.html#forms and then search for prepended inputs).
Add this in the head section of your html
<link rel="icon" type="image/gif/png" href="mouse_select_left.png">
Here is one solution that I would not recommend, but might be useful in some situations where modules were simply not generated:
import os
import sys
parent_dir_name = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
sys.path.append(parent_dir_name + "/your_dir")
import your_script
your_script.a_function()
Because the glyphicons are now fonts, one can use the contextual classes to apply the appropriate color to the icons.
For example:
<span class="glyphicon glyphicon-info-sign text-info"></span>
adding text-info
to the css will make the icon the info blue color.
You can simply add this CSS to your header
<link href='http://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css' rel='stylesheet' type='text/css'>
next add this code in place where you want to display a glyph symbol.
<div class="fa fa-search"></div> <!-- smaller -->
<div class="fa fa-search fa-2x"></div> <!-- bigger -->
Have fun.
This is the easiest way to do what you are trying to do:
<style>
ul {
list-style-type: none;
}
</style>
<ul class="icons">
<li><i class="fa fa-bomb"></i> Lists</li>
<li><i class="fa fa-bomb"></i> Buttons</li>
<li><i class="fa fa-bomb"></i> Button groups</li>
<li><i class="fa fa-bomb"></i> Navigation</li>
<li><i class="fa fa-bomb"></i> Prepended form inputs</li>
</ul>
I suggest keeping your icons separate from FontAwesome and create and maintain your own custom library. Personally, I think it is much easier to maintain keeping FontAwesome separate if you are going to be creating your own icon library. You can then have FontAwesome loaded into your site from a CDN and never have to worry about keeping it up-to-date.
When creating your own custom icons, create each icon via Adobe Illustrator or similar software. Once your icons are created, save each individually in SVG
format on your computer.
Next, head on over to IcoMoon: http://icomoon.io , which has the best font generating software (in my opinion), and it's free. IcoMoon will allow you to import your individual svg-saved fonts into a font library, then generate your custom icon glyph library in eot
, ttf
, woff
, and svg
. One format IcoMoon does not generate is woff2
.
After generating your icon pack at IcoMoon, head over to FontSquirrel: http://fontsquirrel.com and use their font generator. Use your ttf
file generated at IcoMoon. In the newly generated icon pack created, you'll now have your icon pack in woff2
format.
Make sure the files for eot
, ttf
, svg
, woff
, and woff2
are all the same name. You are generating an icon pack from two different websites/software, and they do name their generated output differently.
You'll have CSS generated for your icon pack at both locations. But the CSS generated at IcoMoon will not include the woff2
format in your @font-face {}
declaration. Make sure to add that when you're adding your CSS to your project:
@font-face {
font-family: 'customiconpackname';
src: url('../fonts/customiconpack.eot?lchn8y');
src: url('../fonts/customiconpack.eot?lchn8y#iefix') format('embedded-opentype'),
url('../fonts/customiconpack.ttf?lchn8y') format('truetype'),
url('../fonts/customiconpack.woff2?lchn8y') format('woff'),
url('../fonts/customiconpack.woff?lchn8y') format('woff'),
url('../fonts/customiconpack.svg?lchn8y#customiconpack') format('svg');
font-weight: normal;
font-style: normal;
}
Keep in mind that you can get the glyph unicode values of each icon in your icon pack using the IcoMoon software. These values can be helpful in assigning your icons via CSS, as in (assuming we're using the font-family
declared in the example @font-face {...}
above):
selector:after {
font-family: 'customiconpackname';
content: '\e953';
}
You can also get the glyph unicode value e953
if you open the font-pack-generated svg
file in a text editor. E.g.:
<glyph unicode="" glyph-name="eye" ... />
I take a totally different approach to everyone else's answers here altogether. Let me prefix my solution and argue by stating that sometimes standards and conventions are meant to be broken, especially in the context of the standard HTML lexical tag definitions.
There's nothing to stop you from creating custom elements that are self-descriptive to it's very purpose.
Both modern browsers and even IE 6+ (w/ shim) can support things like:
<icon class="plus">
or
<icon-add>
Just make sure to normalize the tag:
icon { display:block; margin:0; padding:0; border:0; ... }
and use a shim if you need to support IE9 or earlier (see post below).
Check out this StackOverflow Post:
Is there a way to create your own html tag in HTML5
To further my argument, both Google's Angular Directives and the new Polymer projects utilize the concept of custom HTML tags.
I came across the same problem recently. I’m becoming more partial to the “always use a virtualenv” mindset, so my problem was to install virtualenv with pip without installing distribute to my global or user site-packages directory. To do this, I manually downloaded distribute, pip and virtualenv, and for each one I ran “python setup.py install --prefix ~/.local/python-private” (with a temporary setting of PYTHONPATH=~/.local/python-private) so that setup scripts were able to find distribute). I’ve moved the virtualenv script to another directory I have on my PATH and edited it so that the distribute and virtualenv modules can be found on sys.path. Tada: I did not install anything to /usr, /usr/local or my user site-packages dir, but I can run virtualenv anywhere, and in that virtualenv I get pip.
Basically, to make a cross domain AJAX requests, the requested server should allow the cross origin sharing of resources (CORS). You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/
In your scenario, you are setting the headers in the client which in fact needs to be set into http://localhost:8080/app server side code.
If you are using PHP Apache server, then you will need to add following in your .htaccess
file:
Header set Access-Control-Allow-Origin "*"
If you're constructing an array via mutability and then want to return an immutable version, you can simply return the mutable array as an "NSArray" via inheritance.
- (NSArray *)arrayOfStrings {
NSMutableArray *mutableArray = [NSMutableArray array];
mutableArray[0] = @"foo";
mutableArray[1] = @"bar";
return mutableArray;
}
If you "trust" the caller to treat the (technically still mutable) return object as an immutable NSArray, this is a cheaper option than [mutableArray copy]
.
To determine whether it can change a received object, the receiver of a message must rely on the formal type of the return value. If it receives, for example, an array object typed as immutable, it should not attempt to mutate it. It is not an acceptable programming practice to determine if an object is mutable based on its class membership.
The above practice is discussed in more detail here:
Best Practice: Return mutableArray.copy or mutableArray if return type is NSArray
CREATE OR REPLACE FUNCTION IS_NUMERIC(P_INPUT IN VARCHAR2) RETURN INTEGER IS
RESULT INTEGER;
NUM NUMBER ;
BEGIN
NUM:=TO_NUMBER(P_INPUT);
RETURN 1;
EXCEPTION WHEN OTHERS THEN
RETURN 0;
END IS_NUMERIC;

display
is not an attribute - it's a CSS property. You need to access the style object for this:
document.getElementById('classRight').style.display = 'none';
If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:
I think that it really depends on your personal coding style. If you're used to C++, Javascript, etc., you might feel more comfortable using the {} syntax. If you're used to Visual Basic, you might want to use the if : endif; syntax.
I'm not sure one can definitively say one is easier to read than the other - it's personal preference. I usually do something like this:
<?php
if ($foo) { ?>
<p>Foo!</p><?php
} else { ?>
<p>Bar!</p><?php
} // if-else ($foo) ?>
Whether that's easier to read than:
<?php
if ($foo): ?>
<p>Foo!</p><?php
else: ?>
<p>Bar!</p><?php
endif; ?>
is a matter of opinion. I can see why some would feel the 2nd way is easier - but only if you haven't been programming in Javascript and C++ all your life. :)
Set the background property of your navigationBar, e.g.
navigationController?.navigationBar.backgroundColor = UIColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 0.5)
(You may have to change that a bit if you don't have a navigation controller, but that should give you an idea of what to do.)
Also make sure that the view below actually extends under the bar.
The answer from Shivam Kotwalia works perfectly. However, the object is imported as a byte type. Sometimes you may need it as a string for performing REGEX or something like that.
I recommend the following code (two lines from Shivam Kotwalia's answer) :
import textract
text = textract.process("path/to/file.extension")
text = text.decode("utf-8")
The last line will convert the object text to a string.
Strange behavior with MS Excel
:
If i export to "text based, comma-separated format (csv
)" this is the mime-type I get after uploading on my webserver:
[name] => data.csv
[type] => application/vnd.ms-excel
So Microsoft seems to be doing own things again, regardless of existing standards: https://en.wikipedia.org/wiki/Comma-separated_values

Here you can find info on how to upgrade to v3: http://tosbourn.com/2013/08/javascript/upgrading-from-bootstraps-typeahead-to-typeahead-js/

[Speed consideration]
Lot of ppl here suggests ResultSet.last()
but for that you would need to open connection as a ResultSet.TYPE_SCROLL_INSENSITIVE
which for Derby embedded database is up to 10 times SLOWER than ResultSet.TYPE_FORWARD_ONLY
.
According to my micro-tests for embedded Derby and H2 databases it is significantly faster to call SELECT COUNT(*)
before your SELECT.
\tag
also works in align*
. Example:
\begin{align*}
a(x)^{2} &= bx\tag{1}\\
a(x)^{2} &= b\tag{2}\\
ax &= b\tag{3}\\
a(x)^{2}+bx &= c\tag{4}\\
a(x)^{2}+c &= bx\tag{5}\\
a(x)^{2} &= bx+c\tag{6}\\ \\
Where\quad a, b, c \, \in N
\end{align*}
Output:
Try following code:
File file = new File("infilename");
// Get the number of bytes in the file
long sizeInBytes = file.length();
//transform in MB
long sizeInMb = sizeInBytes / (1024 * 1024);
Understanding Requests Body
When receiving a POST or PUT request, the request body might be important to your application. Getting at the body data is a little more involved than accessing request headers. The request object that's passed in to a handler implements the ReadableStream interface. This stream can be listened to or piped elsewhere just like any other stream. We can grab the data right out of the stream by listening to the stream's 'data' and 'end' events.
The chunk emitted in each 'data' event is a Buffer. If you know it's going to be string data, the best thing to do is collect the data in an array, then at the 'end', concatenate and stringify it.
let body = []; request.on('data', (chunk) => { body.push(chunk); }).on('end', () => { body = Buffer.concat(body).toString(); // at this point, `body` has the entire request body stored in it as a string });
Understanding body-parser
As per its documentation
Parse incoming request bodies in a middleware before your handlers, available under the req.body property.
As you saw in the first example, we had to parse the incoming request stream manually to extract the body. This becomes a tad tedious when there are multiple form data of different types. So we use the body-parser package which does all this task under the hood.
It provides four modules to parse different types of data
After having the raw content body-parser will use one of the above strategies(depending on middleware you decided to use) to parse the data. You can read more about them by reading their documentation.
After setting the req.body
to the parsed body, body-parser will invoke next()
to call the next middleware down the stack, which can then access the request data without having to think about how to unzip and parse it.
Use time.sleep()
from time import sleep
sleep(0.05)
I get this error sometimes when AJAX updates are midway. Capybara appears to be pretty smart about waiting for DOM changes (see Why wait_until was removed from Capybara ), but the default wait time of 2 seconds was simply not enough in my case. Changed in _spec_helper.rb_ with e.g.
Capybara.default_max_wait_time = 5
You need to add the following to your Profile (Works on MacOS):
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
No need to patch anything.
Ensure two things in the AVD manager utility for the emulator:
SD Card size is mentioned e.g. 512.
From the Hardware tag, press New and select "SD Card Support" from the drop down menu.
Now, start the emulator. SD Card shall now support writing as well.
as the base question is about win forms here is the solution : ( I just changed the code by user1032413 to rflect windowsForms settings ) if it's a new key :
Configuration config = configurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings.Add("Key","Value");
config.Save(ConfigurationSaveMode.Modified);
if the key already exists :
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings["Key"].Value="Value";
config.Save(ConfigurationSaveMode.Modified);
I've made basic black launch screens that will make the app scale properly on the iPhone 6 and iPhone 6+:
If you already have a LaunchImage in your .xcassett, open it, switch to the third tab in the right menu in Xcode and tick the iOS 8.0 iPhone images to add them to the existing set. Then drag the images over:
The other solutions are great for a single if
/ else
construct. However, ternary statements within list comprehensions are arguably difficult to read.
Using a function aids readability, but such a solution is difficult to extend or adapt in a workflow where the mapping is an input. A dictionary can alleviate these concerns:
row = [None, 'This', 'is', 'a', 'filler', 'test', 'string', None]
d = {None: '', 'filler': 'manipulated'}
res = [d.get(x, x) for x in row]
print(res)
['', 'This', 'is', 'a', 'manipulated', 'test', 'string', '']
I needed to remove any trailing zeros but keep at least 2 decimals, including any zeros.
The numbers I'm working with are 6 decimal number strings, generated by .toFixed(6).
Expected Result:
var numstra = 12345.000010 // should return 12345.00001
var numstrb = 12345.100000 // should return 12345.10
var numstrc = 12345.000000 // should return 12345.00
var numstrd = 12345.123000 // should return 12345.123
Solution:
var numstr = 12345.100000
while (numstr[numstr.length-1] === "0") {
numstr = numstr.slice(0, -1)
if (numstr[numstr.length-1] !== "0") {break;}
if (numstr[numstr.length-3] === ".") {break;}
}
console.log(numstr) // 12345.10
Logic:
Run loop function if string last character is a zero.
Remove the last character and update the string variable.
If updated string last character is not a zero, end loop.
If updated string third to last character is a floating point, end loop.
You can "fake it" by creating a new HttpContext
like this:
I've taken that code and put it on an static helper class like so:
public static HttpContext FakeHttpContext()
{
var httpRequest = new HttpRequest("", "http://example.com/", "");
var stringWriter = new StringWriter();
var httpResponse = new HttpResponse(stringWriter);
var httpContext = new HttpContext(httpRequest, httpResponse);
var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
new HttpStaticObjectsCollection(), 10, true,
HttpCookieMode.AutoDetect,
SessionStateMode.InProc, false);
httpContext.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
BindingFlags.NonPublic | BindingFlags.Instance,
null, CallingConventions.Standard,
new[] { typeof(HttpSessionStateContainer) },
null)
.Invoke(new object[] { sessionContainer });
return httpContext;
}
Or instead of using reflection to construct the new HttpSessionState
instance, you can just attach your HttpSessionStateContainer
to the HttpContext
(as per Brent M. Spell's comment):
SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer);
and then you can call it in your unit tests like:
HttpContext.Current = MockHelper.FakeHttpContext();
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
For CentOS Linux release 7.3
The mysql.sock file path is /var/lib/mysql/mysql.sock
Edit /etc/my.cnf file and put below entry
This will solve your problem.
[client]
user=root
password=Passw0rd
port=3306
socket=/var/lib/mysql/mysql.sock
[mysqld]
bind-address=0.0.0.0
After this restart the service
service mysql restart
This is what I've been doing if you need to do something iterative... but it would be wise to look for set operations first. Also, do not do this because you don't want to learn cursors.
select top 1000 TableID
into #ControlTable
from dbo.table
where StatusID = 7
declare @TableID int
while exists (select * from #ControlTable)
begin
select top 1 @TableID = TableID
from #ControlTable
order by TableID asc
-- Do something with your TableID
delete #ControlTable
where TableID = @TableID
end
drop table #ControlTable
You're thinking too complicated. It's actually just $('#'+openaddress)

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.
What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?
You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.
The problem you're having is the NSAutoresizingMaskLayoutConstraints should not be in there. This is the old system of springs and struts. To get rid of it, run this method on each view that you're wanting to constrain:
[view setTranslatesAutoresizingMaskIntoConstraints:NO];
If you're using Amazon Linux it's CentOS-based, which is RedHat-based. RH-based installs use yum
not apt-get
. Something like yum search httpd
should show you the available Apache packages - you likely want yum install httpd24
.
Note: Amazon Linux 2 has diverged from CentOS since the writing of this answer, but still uses
yum
.
This thread seems to be quite old. If anyone's still looking, the steps mentioned here : https://github.com/burnash/gspread work very well.
import gspread
from oauth2client.service_account import ServiceAccountCredentials
import os
os.chdir(r'your_path')
scope = ['https://spreadsheets.google.com/feeds',
'https://www.googleapis.com/auth/drive']
creds = ServiceAccountCredentials.from_json_keyfile_name('client_secret.json', scope)
gc = gspread.authorize(creds)
wks = gc.open("Trial_Sheet").sheet1
wks.update_acell('H3', "I'm here!")
Make sure to drop your credentials json file in your current directory. Rename it as client_secret.json.
You might run into errors if you don't enable Google Sheet API with your current credentials.
Try this:

When a chip gets power all of it's registers contain random values. It's not possible to have an an initial value. It will always be random.
This is why we have reset signals, to reset registers to a known value. The reset is controlled by something off chip, and we write our code to use it.
always @(posedge clk) begin
if (reset == 1) begin // For an active high reset
data_reg = 8'b10101011;
end else begin
data_reg = next_data_reg;

Sadly, I think that JSTL doesn't support anything but an iteration through all elements to figure this out. In the past, I've used the forEach method in the core tag library:
<c:set var="contains" value="false" />
<c:forEach var="item" items="${myList}">
<c:if test="${item eq myValue}">
<c:set var="contains" value="true" />
</c:if>
</c:forEach>
After this runs, ${contains} will be equal to "true" if myList contained myValue.

Try data.table's :=
operator :
DT = as.data.table(df)
DT[b==0, est := (a-5)/2.533]
It's fast and short. See these linked questions for more information on :=
:

If you want to jump directly to the desired position in a listView just use
listView.setSelection(int position);
and if you want to jump smoothly to the desired position in listView just use
listView.smoothScrollToPosition(int position);
You JSON doesn't match your struct fields: E.g. "district" in JSON and "District" as the field.
Also: Your Item is a slice type but your JSON is a dict value. Do not mix this up. Slices decode from arrays.
I am reading a book (Effective Python) by Brett Slatkin and he shows another way to iterate over a list and also know the index of the current item in the list but he suggests that it is better not to use it and to use enumerate
instead.
I know you asked what enumerate means, but when I understood the following, I also understood how enumerate
makes iterating over a list while knowing the index of the current item easier (and more readable).
list_of_letters = ['a', 'b', 'c']
for i in range(len(list_of_letters)):
letter = list_of_letters[i]
print (i, letter)
The output is:
0 a
1 b
2 c
I also used to do something, even sillier before I read about the enumerate
function.
i = 0
for n in list_of_letters:
print (i, n)
i += 1
It produces the same output.
But with enumerate
I just have to write:
list_of_letters = ['a', 'b', 'c']
for i, letter in enumerate(list_of_letters):
print (i, letter)
SelectedText = this.combobox.SelectionBoxItem.ToString();
Checking in from 2015: We now have native promises in most recent browser (Edge 12, Firefox 40, Chrome 43, Safari 8, Opera 32 and Android browser 4.4.4 and iOS Safari 8.4, but not Internet Explorer, Opera Mini and older versions of Android).
If we want to perform 10 async actions and get notified when they've all finished, we can use the native Promise.all
, without any external libraries:
function asyncAction(i) {
return new Promise(function(resolve, reject) {
var result = calculateResult();
if (result.hasError()) {
return reject(result.error);
}
return resolve(result);
});
}
var promises = [];
for (var i=0; i < 10; i++) {
promises.push(asyncAction(i));
}
Promise.all(promises).then(function AcceptHandler(results) {
handleResults(results),
}, function ErrorHandler(error) {
handleError(error);
});
If a pipeline is too complicated to wrap in $(...)
, consider writing a function. Any local variables available at the time of definition will be accessible.
function getHash {
genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5
}

Another more efficient way to do is just use @Value
@Value("classpath:sss.json")
private Resource resource;
and after that you can just get the file this way
File file = resource.getFile();
If I want the sort to be applied to only one of the UNION if use Union all:
Select id,name,age
From Student
Where age < 15
Union all
Select id,name,age
From
(
Select id,name,age
From Student
Where Name like "%a%"
Order by name
)
SELECT COLUMN_NAME FROM {DATABASENAME}.INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE TABLE_NAME LIKE '{TABLENAME}' AND CONSTRAINT_NAME LIKE 'PK%'
WHERE
{DATABASENAME} = your database from your server AND
{TABLENAME} = your table name from which you want to see the primary key.NOTE : enter your database name and table name without brackets.
As wordpress api has changed, you can´t use get_posts with param 'post_name'. I´ve modified Maartens function a bit:
function get_post_id_by_slug( $slug, $post_type = "post" ) {
$query = new WP_Query(
array(
'name' => $slug,
'post_type' => $post_type,
'numberposts' => 1,
'fields' => 'ids',
) );
$posts = $query->get_posts();
return array_shift( $posts );
}
In this part of your SP:
IF @DateFirst <> '' and @DateLast <> ''
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + @DateFirst
+ ' and convert (Date,DateLog) <=''' + @DateLast
you are trying to concatenate strings and datetimes.
As the datetime
type has higher priority than varchar
/nvarchar
, the +
operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= '''
and others) to datetime or numeric values. And fails.
That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.
To amend the situation, you need to add explicit casting of your datetime variables to strings:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst)
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)
You'll also need to add closing single quotes:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst) + ''''
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''
If you don't want the lines in between the list items to be indented, like user Mars mentioned in his comment, you can use pandoc
's example_lists
feature. From their docs:
(@) My first example will be numbered (1).
(@) My second example will be numbered (2).
Explanation of examples.
(@) My third example will be numbered (3).
Just try this line:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
angular.module('myApp').controller('myCtrl', function($scope, $rootScope) {
var a = //something in the scope
//put it in the root scope
$rootScope.test = "TEST";
});
angular.module('myApp').controller('myCtrl2', function($scope, $rootScope) {
var b = //get var a from root scope somehow
//use var b
$scope.value = $rootScope.test;
alert($scope.value);
// var b = $rootScope.test;
// alert(b);
});
DateTime.Now.ToShortTimeString().ToString()

There is not much information on the nature of the problem and the data, so difficult to advise. However, would recommend to assess the feasibility of other solutions, that can be easier to integrate with java and enables horizontal as well as vertical scaling. The first I would suggest to look at is an open source analytical engine called Apache Spark https://spark.apache.org/ that is available on Microsoft Azure but probably on other cloud IaaS providers too. If you stick to involving your GPU then the suggestion is to look at other GPU supported analytical databases on the market that fits in the budget of your organisation.

db:migrate runs (single) migrations that have not run yet.
db:create creates the database
db:drop deletes the database
db:schema:load creates tables and columns within the existing database following schema.rb. This will delete existing data.
db:setup does db:create, db:schema:load, db:seed
db:reset does db:drop, db:setup
db:migrate:reset does db:drop, db:create, db:migrate
Typically, you would use db:migrate after having made changes to the schema via new migration files (this makes sense only if there is already data in the database). db:schema:load is used when you setup a new instance of your app.
I hope that helps.
UPDATE for rails 3.2.12:
I just checked the source and the dependencies are like this now:
db:create creates the database for the current env
db:create:all creates the databases for all envs
db:drop drops the database for the current env
db:drop:all drops the databases for all envs
db:migrate runs migrations for the current env that have not run yet
db:migrate:up runs one specific migration
db:migrate:down rolls back one specific migration
db:migrate:status shows current migration status
db:rollback rolls back the last migration
db:forward advances the current schema version to the next one
db:seed (only) runs the db/seed.rb file
db:schema:load loads the schema into the current env's database
db:schema:dump dumps the current env's schema (and seems to create the db as well)
db:setup runs db:schema:load, db:seed
db:reset runs db:drop db:setup

Since I also had the same problem of "How to detect a docker daemon port" however I had on OSX and after little digging in I found the answer. I thought to share the answer here for people coming from osx.
If you visit known-issues from docker for mac and github issue, you will find that by default the docker daemon only listens on unix socket /var/run/docker.sock
and not on tcp. The default port for docker is 2375 (unencrypted) and 2376(encrypted) communication over tcp(although you can choose any other port).
On OSX its not straight forward to run the daemon on tcp port. To do this one way is to use socat
container to redirect the Docker API exposed on the unix domain socket to the host port on OSX.
docker run -d -v /var/run/docker.sock:/var/run/docker.sock -p 127.0.0.1:2375:2375 bobrik/socat TCP-LISTEN:2375,fork UNIX-CONNECT:/var/run/docker.sock
and then
export DOCKER_HOST=tcp://localhost:2375
However for local client on mac os you don't need to export DOCKER_HOST variable to test the api.
You should bind the tap event, the click does not exist on mobile safari or in the UIWbview. You can also use this polyfill ,to avoid the 300ms delay when a link is touched.
I was also getting same issue as i tried using value 0 in non-based indexing,i.e starting with 1, not with zero
Spring Boot, v2.3.0.RELEASE
Recommended (In application.properties):
logging.level.org.hibernate.SQL=DEBUG //logs all SQL DML statements
logging.level.org.hibernate.type=TRACE //logs all JDBC parameters
parameters
Note:
The above will not give you a pretty-print though.
You can add it as a configuration:
properties.put("hibernate.format_sql", "true");
or as per below.
Works but NOT recommended
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
Reason: It's better to let the logging framework manage/optimize the output for you + it doesn't give you the prepared statement parameters.

Use encodeURI()
in client JS and use URLDecoder.decode()
in server Java side works.
Example:
Javascript:
$.getJSON(
url,
{
"user": encodeURI(JSON.stringify(user))
},
onSuccess
);
Java:
java.net.URLDecoder.decode(params.user, "UTF-8");
In my case; my WCF service function was using List<byte> Types
parameter and i was getting this exception in the client side. Then i changed it to byte[] Types
, updated service reference and problem is solved.
it's better to use whereargs too;
db.delete("tablename","id=? and name=?",new String[]{"1","jack"});
this is like useing this command:
delete from tablename where id='1' and name ='jack'
and using delete function in such way is good because it removes sql injections.
With fetch api it turned out that you do NOT have to include headers "Content-type": "multipart/form-data".
So the following works:
let formData = new FormData()
formData.append("nameField", fileToSend)
fetch(yourUrlToPost, {
method: "POST",
body: formData
})
Note that with axios I had to use the content-type.
This should give you the current date minus 1 year:
select now() - interval '1 year';
Window function may solve that in one pass:
SELECT DISTINCT ON (address_id)
LAST_VALUE(purchases.address_id) OVER wnd AS address_id
FROM "purchases"
WHERE "purchases"."product_id" = 1
WINDOW wnd AS (
PARTITION BY address_id ORDER BY purchases.purchased_at DESC
ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
According to @Abhishek Singh's you need to understand the problem:
What is the line which gives exception ?? The reason for this is because the element to which you have referred is removed from the DOM structure
and you can not refer to it anymore (imagine what element's ID has changed).
Follow the code:
class TogglingPage {
@FindBy(...)
private WebElement btnTurnOff;
@FindBy(...)
private WebElement btnTurnOn;
TogglingPage turnOff() {
this.btnTurnOff.isDisplayed();
this.btnTurnOff.click(); // when clicked, button should swap into btnTurnOn
this.btnTurnOn.isDisplayed();
this.btnTurnOn.click(); // when clicked, button should swap into btnTurnOff
this.btnTurnOff.isDisplayed(); // throws an exception
return new TogglingPage();
}
}
Now, let us wonder why?
btnTurnOff
was found by a driver - okbtnTurnOff
was replaced by btnTurnOn
- okbtnTurnOn
was found by a driver. - okbtnTurnOn
was replaced by btnTurnOff
- okthis.btnTurnOff.isDisplayed();
on the element which does not exist anymore in Selenium sense - you can see it, it works perfectly, but it is a different instance of the same button. Possible fix:
TogglingPage turnOff() {
this.btnTurnOff.isDisplayed();
this.btnTurnOff.click();
TogglingPage newPage = new TogglingPage();
newPage.btnTurnOn.isDisplayed();
newPage.btnTurnOn.click();
TogglingPage newerPage = new TogglingPage();
newerPage.btnTurnOff.isDisplayed(); // ok
return newerPage;
}
So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]
Python dictionaries have a key and a value, what you are asking for is what key(s) point to a given value.
You can only do this in a loop:
[k for (k, v) in i.iteritems() if v == 0]
Note that there can be more than one key per value in a dict; {'a': 0, 'b': 0}
is perfectly legal.
If you want ordering you either need to use a list or a OrderedDict instance instead:
items = ['a', 'b', 'c']
items.index('a') # gives 0
items[0] # gives 'a'
The official MS line is "because it's not a functional operation" (ie it's a stateful operation).
Couldn't you do something like:
list.Select( x => x+1 )
or if you really need it in a List:
var someValues = new List<int>( list.Select( x => x+1 ) );
There are a few places you can do versioning in a REST API:
As noted, in the URI. This can be tractable and even esthetically pleasing if redirects and the like are used well.
In the Accepts: header, so the version is in the filetype. Like 'mp3' vs 'mp4'. This will also work, though IMO it works a bit less nicely than...
In the resource itself. Many file formats have their version numbers embedded in them, typically in the header; this allows newer software to 'just work' by understanding all existing versions of the filetype while older software can punt if an unsupported (newer) version is specified. In the context of a REST API, it means that your URIs never have to change, just your response to the particular version of data you were handed.
I can see reasons to use all three approaches:
You can use sp_lock
(and sp_lock2
), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks
:
select
object_name(p.object_id) as TableName,
resource_type, resource_description
from
sys.dm_tran_locks l
join sys.partitions p on l.resource_associated_entity_id = p.hobt_id
To do this without rewriting history (i.e. if you've already pushed the commits):
git checkout master
git revert <commitID(s)>
git checkout -b new-branch
git cherry-pick <commitID(s)>
Both branches can then be pushed without force!
You could only convert a JSON array into a CSV file.
Lets say, you have a JSON like the following :
{"infile": [{"field1": 11,"field2": 12,"field3": 13},
{"field1": 21,"field2": 22,"field3": 23},
{"field1": 31,"field2": 32,"field3": 33}]}
Lets see the code for converting it to csv :
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.json.CDL;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class JSON2CSV {
public static void main(String myHelpers[]){
String jsonString = "{\"infile\": [{\"field1\": 11,\"field2\": 12,\"field3\": 13},{\"field1\": 21,\"field2\": 22,\"field3\": 23},{\"field1\": 31,\"field2\": 32,\"field3\": 33}]}";
JSONObject output;
try {
output = new JSONObject(jsonString);
JSONArray docs = output.getJSONArray("infile");
File file=new File("/tmp2/fromJSON.csv");
String csv = CDL.toString(docs);
FileUtils.writeStringToFile(file, csv);
} catch (JSONException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Now you got the CSV generated from JSON.
It should look like this:
field1,field2,field3
11,22,33
21,22,23
31,32,33
The maven dependency was like,
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20090211</version>
</dependency>
Update Dec 13, 2019:
Updating the answer, since now we can support complex JSON Arrays as well.
import java.nio.file.Files;
import java.nio.file.Paths;
import com.github.opendevl.JFlat;
public class FlattenJson {
public static void main(String[] args) throws Exception {
String str = new String(Files.readAllBytes(Paths.get("path_to_imput.json")));
JFlat flatMe = new JFlat(str);
//get the 2D representation of JSON document
flatMe.json2Sheet().headerSeparator("_").getJsonAsSheet();
//write the 2D representation in csv format
flatMe.write2csv("path_to_output.csv");
}
}
dependency and docs details are in link
dbo is the default schema in SQL Server. You can create your own schemas to allow you to better manage your object namespace.
$('body').bind('beforeunload',function(){
//do something
});
But this wont save any info for later, unless you were planning on saving that in a cookie somewhere (or local storage) and the unload
event does not always fire in all browsers.
Example: http://jsfiddle.net/maniator/qpK7Y/
Code:
$(window).bind('beforeunload',function(){
//save info somewhere
return 'are you sure you want to leave?';
});
In Symfony 3.3 you can use
$projectRoot = $this->get('kernel')->getProjectDir();
to get the web/project root.
if you have repository for entity Foo
and need to select all entries with exact string value boo
(also works for other primitive types or entity types). Put this into your repository interface:
List<Foo> findByBoo(String boo);
if you need to order results:
List<Foo> findByBooOrderById(String boo);
See more at reference.
It is easy, but takes 3 steps:
All rows will be fetched into the "Query Result" window!
If you have a hidden field like this
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("VertragNr") %>'/>
Now you can use your value like this
$(this).parent().find('input[type=hidden]').val()
You can include JQuery using any of the following:
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
- http://code.jquery.com/jquery-latest.min.js (never use this link on production server)
Your code placement can look something like this
```
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
$(document).ready(function(){
$('input[type=radio]').change(function() {
$('input[type=radio]').each(function(index) {
$(this).closest('tr').removeClass('selected');
});
$(this).closest('tr').addClass('selected');
});
});
</script>
```
If you are really about to work on multi-gigabyte text files then do not use PowerShell. Even if you find a way to read it faster processing of huge amount of lines will be slow in PowerShell anyway and you cannot avoid this. Even simple loops are expensive, say for 10 million iterations (quite real in your case) we have:
# "empty" loop: takes 10 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) {} }
# "simple" job, just output: takes 20 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i } }
# "more real job": 107 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i.ToString() -match '1' } }
UPDATE: If you are still not scared then try to use the .NET reader:
$reader = [System.IO.File]::OpenText("my.log")
try {
for() {
$line = $reader.ReadLine()
if ($line -eq $null) { break }
# process the line
$line
}
}
finally {
$reader.Close()
}
UPDATE 2
There are comments about possibly better / shorter code. There is nothing wrong with the original code with for
and it is not pseudo-code. But the shorter (shortest?) variant of the reading loop is
$reader = [System.IO.File]::OpenText("my.log")
while($null -ne ($line = $reader.ReadLine())) {
$line
}
This way I solved my problem. Hope it helps others. In my case I created a class, a field, their getter & setter and then provide the object instead of string.
Use this
public static class EncryptedData {
private String encryptedData;
public String getEncryptedData() {
return encryptedData;
}
public void setEncryptedData(String encryptedData) {
this.encryptedData = encryptedData;
}
}
@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
try {
Path path = Paths.get(PUBLIC_KEY);
byte[] bytes = Files.readAllBytes(path);
PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);
Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
cipher.init(Cipher.PRIVATE_KEY, privateKey);
String decryptedData = new String(cipher.doFinal(encryptedData.getEncryptedData().getBytes()));
String[] dataArray = decryptedData.split("|");
Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
updateIp.invoke(null, dataArray[0], dataArray[1]);
} catch (Exception e) {
LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
}
return null;
Instead of this
@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
try {
Path path = Paths.get(PUBLIC_KEY);
byte[] bytes = Files.readAllBytes(path);
PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);
Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
cipher.init(Cipher.PRIVATE_KEY, privateKey);
String decryptedData = new String(cipher.doFinal(encryptedData.getBytes()));
String[] dataArray = decryptedData.split("|");
Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
updateIp.invoke(null, dataArray[0], dataArray[1]);
} catch (Exception e) {
LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
}
return null;
}
you could disable the network of the host instead!
You need to set the correct content type and stringify your object.
var arr = {City:'Moscow', Age:25};
$.ajax({
url: "Ajax.ashx",
type: "POST",
data: JSON.stringify(arr),
dataType: 'json',
async: false,
contentType: 'application/json; charset=utf-8',
success: function(msg) {
alert(msg);
}
});
The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize can be used as an integer larger than any practical list or string index. It conforms to the implementation’s “natural” integer size and is typically the same as sys.maxint in previous releases on the same platform (assuming the same build options).

Int64 Int64_Num = Source_Num;
byte Byte_Num;
byte[] Byte_Arr = new byte[8];
for (int i = 0; i < 8; i++)
{
if (Source_Num > 255)
{
Int64_Num = Source_Num / 256;
Byte_Num = (byte)(Source_Num - Int64_Num * 256);
}
else
{
Byte_Num = (byte)Int64_Num;
Int64_Num = 0;
}
Byte_Arr[i] = Byte_Num;
Source_Num = Int64_Num;
}
return (Byte_Arr);
}
I've done something a bit different. Not the best, but it works for me. Maybe it could be "genericized".
private static final Object[][] ENTRIES =
{
{new Integer(1), "one"},
{new Integer(2), "two"},
};
private static final Map myMap = newMap(ENTRIES);
private static Map newMap(Object[][] entries)
{
Map map = new HashMap();
for (int x = 0; x < entries.length; x++)
{
Object[] entry = entries[x];
map.put(entry[0], entry[1]);
}
return map;
}
I believe that aspect ratio is width divided by height.

This topic is old but if other people like me search a solution, this is a solution that I have found:
Public Function DBStats() As Boolean
On Error GoTo errorHandler
If Not IsNull(myBase.Version) Then
DBStats = True
End If
Exit Function
errorHandler:
DBStats = False
End Function
So "myBase" is a Database Object, I have made a class to access to database (class with insert, update etc...) and on the module the class is use declare in an object (obviously) and I can test the connection with "[the Object].DBStats":
Dim BaseAccess As New myClass
BaseAccess.DBOpen 'I open connection
Debug.Print BaseAccess.DBStats ' I test and that tell me true
BaseAccess.DBClose ' I close the connection
Debug.Print BaseAccess.DBStats ' I test and tell me false
Edit : In DBOpen I use "OpenDatabase" and in DBClose I use ".Close" and "set myBase = nothing" Edit 2: In the function, if you are not connect, .version give you an error so if aren't connect, the errorHandler give you false
LocalDateTime.parse(
"2016-01-23 12:34".replace( " " , "T" )
)
.atZone( ZoneId.of( "Asia/Karachi" ) )
.plusMinutes( 10 )
Use the excellent java.time classes for date-time work. These classes supplant the troublesome old date-time classes such as java.util.Date
and java.util.Calendar
.
The java.time classes use standard ISO 8601 formats by default for parsing/generating strings of date-time values. To make your input string comply, replace the SPACE in the middle with a T
.
String input = "2016-01-23 12:34" ;
String inputModified = input.replace( " " , "T" );
LocalDateTime
Parse your input string as a LocalDateTime
as it lacks any info about time zone or offset-from-UTC.
LocalDateTime ldt = LocalDateTime.parse( inputModified );
Add ten minutes.
LocalDateTime ldtLater = ldt.plusMinutes( 10 );
ldt.toString(): 2016-01-23T12:34
ldtLater.toString(): 2016-01-23T12:44
That LocalDateTime
has no time zone, so it does not represent a point on the timeline. Apply a time zone to translate to an actual moment. Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
, or Asia/Karachi
. Never use the 3-4 letter abbreviation such as EST
or IST
or PKT
as they are not true time zones, not standardized, and not even unique(!).
ZonedDateTime
If you know the intended time zone for this value, apply a ZoneId
to get a ZonedDateTime
.
ZoneId z = ZoneId.of( "Asia/Karachi" );
ZonedDateTime zdt = ldt.atZone( z );
zdt.toString(): 2016-01-23T12:44+05:00[Asia/Karachi]
Think about whether to add those ten minutes before or after adding a time zone. You may get a very different result because of anomalies such as Daylight Saving Time (DST) that shift the wall-clock time.
Whether you should add the 10 minutes before or after adding the zone depends on the meaning of your business scenario and rules.
Tip: When you intend a specific moment on the timeline, always keep the time zone information. Do not lose that info, as done with your input data. Is the value 12:34
meant to be noon in Pakistan or noon in France or noon in Québec? If you meant noon in Pakistan, say so by including at least the offset-from-UTC (+05:00
), and better still, the name of the time zone (Asia/Karachi
).
Instant
If you want the same moment as seen through the lens of UTC, extract an Instant
. The Instant
class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).
Instant instant = zdt.toInstant();
Avoid the troublesome old date-time classes whenever possible. But if you must, you can convert. Call new methods added to the old classes.
java.util.Date utilDate = java.util.Date.from( instant );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to java.time.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.

matches preceding match zero or more timesSo, ^.*$
means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.
Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones
and Matthew's last name is Jones
. The pattern ^Matt.*Jones$
will match Matthew's last name is Jones
. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.
Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.
Another idea is to use a setting in the Shared Preferences. Same general idea as checking for an empty file, but then you don't have an empty file floating around, not being used to store anything
The polynomial for CRC32 is:
x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1
Or in hex and binary:
0x 01 04 C1 1D B7
1 0000 0100 1100 0001 0001 1101 1011 0111
The highest term (x32) is usually not explicitly written, so it can instead be represented in hex just as
0x 04 C1 1D B7
Feel free to count the 1s and 0s, but you'll find they match up with the polynomial, where 1
is bit 0 (or the first bit) and x
is bit 1 (or the second bit).
Why this polynomial? Because there needs to be a standard given polynomial and the standard was set by IEEE 802.3. Also it is extremely difficult to find a polynomial that detects different bit errors effectively.
You can think of the CRC-32 as a series of "Binary Arithmetic with No Carries", or basically "XOR and shift operations". This is technically called Polynomial Arithmetic.
To better understand it, think of this multiplication:
(x^3 + x^2 + x^0)(x^3 + x^1 + x^0)
= (x^6 + x^4 + x^3
+ x^5 + x^3 + x^2
+ x^3 + x^1 + x^0)
= x^6 + x^5 + x^4 + 3*x^3 + x^2 + x^1 + x^0
If we assume x is base 2 then we get:
x^7 + x^3 + x^2 + x^1 + x^0
Why? Because 3x^3 is 11x^11 (but we need only 1 or 0 pre digit) so we carry over:
=1x^110 + 1x^101 + 1x^100 + 11x^11 + 1x^10 + 1x^1 + x^0
=1x^110 + 1x^101 + 1x^100 + 1x^100 + 1x^11 + 1x^10 + 1x^1 + x^0
=1x^110 + 1x^101 + 1x^101 + 1x^11 + 1x^10 + 1x^1 + x^0
=1x^110 + 1x^110 + 1x^11 + 1x^10 + 1x^1 + x^0
=1x^111 + 1x^11 + 1x^10 + 1x^1 + x^0
But mathematicians changed the rules so that it is mod 2. So basically any binary polynomial mod 2 is just addition without carry or XORs. So our original equation looks like:
=( 1x^110 + 1x^101 + 1x^100 + 11x^11 + 1x^10 + 1x^1 + x^0 ) MOD 2
=( 1x^110 + 1x^101 + 1x^100 + 1x^11 + 1x^10 + 1x^1 + x^0 )
= x^6 + x^5 + x^4 + 3*x^3 + x^2 + x^1 + x^0 (or that original number we had)
I know this is a leap of faith but this is beyond my capability as a line-programmer. If you are a hard-core CS-student or engineer I challenge to break this down. Everyone will benefit from this analysis.
So to work out a full example:
Original message : 1101011011
Polynomial of (W)idth 4 : 10011
Message after appending W zeros : 11010110110000
Now we divide the augmented Message by the Poly using CRC arithmetic. This is the same division as before:
1100001010 = Quotient (nobody cares about the quotient)
_______________
10011 ) 11010110110000 = Augmented message (1101011011 + 0000)
=Poly 10011,,.,,....

1110 = Remainder = THE CHECKSUM!!!!
The division yields a quotient, which we throw away, and a remainder, which is the calculated checksum. This ends the calculation. Usually, the checksum is then appended to the message and the result transmitted. In this case the transmission would be: 11010110111110.
Only use a 32-bit number as your divisor and use your entire stream as your dividend. Throw out the quotient and keep the remainder. Tack the remainder on the end of your message and you have a CRC32.
Average guy review:
QUOTIENT
----------
DIVISOR ) DIVIDEND
= REMAINDER
(Note that the stream has to be dividable by 32 bits or it should be padded. For example, an 8-bit ANSI stream would have to be padded. Also at the end of the stream, the division is halted.)
private static T[] prepareArray<T>(T[] arrayToCopy, T value)

return (T[])arrayToCopy;
}
I was performing this throughout my code and wanted a way to put it into a method. I wanted to share this here because I didn't have to use the Convert.ChangeType for my return value. This may not be a best practice but it worked for me. This method takes in an array of generic type and a value to add to the end of the array. The array is then copied with the first value stripped and the value taken into the method is added to the end of the array. The last thing is that I return the generic array.
From Oracle docs, Date.toString() method convert Date object to a String of the specific form - do not use toString method on Date object. Try to use:
String stringDate = new SimpleDateFormat(YOUR_STRING_PATTERN).format(yourDateObject);
Next step is parse stringDate to Date:
Date date = new SimpleDateFormat(OUTPUT_PATTERN).parse(stringDate);
Note that, parse method throws ParseException
this worked for me:
var blobToBase64 = function(blob, callback) {
var reader = new FileReader();
reader.onload = function() {
var dataUrl = reader.result;
var base64 = dataUrl.split(',')[1];
callback(base64);
};
reader.readAsDataURL(blob);
};

You can search "slashdot effect analysis" for graphs of what you would see if some aspect of the site suddenly became popular in the news, e.g. this graph on wiki.
Web-applications that survive tend to be the ones which can generate static pages instead of putting every request through a processing language.
There was an excellent video (I think it might have been on ted.com? I think it might have been by flickr web team? Does someone know the link?) with ideas on how to scale websites beyond the single server, e.g. how to allocate connections amongst the mix of read-only and read-write servers to get best effect for various types of users.
Receiving a status 429 is not an error, it is the other server "kindly" asking you to please stop spamming requests. Obviously, your rate of requests has been too high and the server is not willing to accept this.
You should not seek to "dodge" this, or even try to circumvent server security settings by trying to spoof your IP, you should simply respect the server's answer by not sending too many requests.
If everything is set up properly, you will also have received a "Retry-after" header along with the 429 response. This header specifies the number of seconds you should wait before making another call. The proper way to deal with this "problem" is to read this header and to sleep your process for that many seconds.
You can find more information on status 429 here: http://tools.ietf.org/html/rfc6585#page-3
For each iteration of the ng-repeat loop, line
is a reference to an object in your array. Therefore, to preview the value, use {{line.text}}
.
Similarly, to databind to the text, databind to the same: ng-model="line.text"
. You don't need to use value
when using ng-model (actually you shouldn't).
For a more in-depth look at scopes and ng-repeat, see What are the nuances of scope prototypal / prototypical inheritance in AngularJS?, section ng-repeat.
The s.insert(0, x)
form is the most common.
Whenever you see it though, it may be time to consider using a collections.deque instead of a list.

For those of us using ASP.NET MVC 4 - this may be helpful.
First, I added a BundleConfig class in the App_Start folder.
Here’s my code that I used to create it:
using System.Web.Optimization;
public class BundleConfig
{
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/SiteMaster.css"));
}
}
Second, I registered the BundleConfig class in the Global.asax file:
protected void Application_Start()
{
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
Third, I added style helpers to the my CSS file:
/* Styles for validation helpers */
.field-validation-error {
color: red;
font-weight: bold;
}
.field-validation-valid {
display: none;
}
input.input-validation-error {
border: 1px solid #e80c4d;
}
input[type="checkbox"].input-validation-error {
border: 0 none;
}
.validation-summary-errors {
color: #e80c4d;
font-weight: bold;
font-size: 1.1em;
}
.validation-summary-valid {
display: none;
}
Finally I used this syntax in any View:
@Styles.Render("~/Content/css")
Colon does not have special meaning in a character class and does not need to be escaped. According to the PHP regex docs, the only characters that need to be escaped in a character class are the following:
All non-alphanumeric characters other than
\
,-
,^
(at the start) and the terminating]
are non-special in character classes, but it does no harm if they are escaped.
For more info about Java regular expressions, see the docs.
Use if(index.length() < 0)
for Integer
or
Use if(index.equals(null)
for String
This isn't added out of the box because the Angular team wants Angular 2 to run minified. OrderBy runs off of reflection which breaks with minification. Check out Miško Heverey's response on the matter.
I've taken the time to create an OrderBy pipe that supports both single and multi-dimensional arrays. It also supports being able to sort on multiple columns of the multi-dimensional array.
<li *ngFor="let person of people | orderBy : ['-lastName', 'age']">{{person.firstName}} {{person.lastName}}, {{person.age}}</li>
This pipe does allow for adding more items to the array after rendering the page, and still sort the arrays with the new items correctly.
I have a write up on the process here.
And here's a working demo: http://fuelinteractive.github.io/fuel-ui/#/pipe/orderby and https://plnkr.co/edit/DHLVc0?p=info
EDIT: Added new demo to http://fuelinteractive.github.io/fuel-ui/#/pipe/orderby
EDIT 2: Updated ngFor to new syntax
If you want to have a behavior similar to JMP, creating column titles that keep all info from the multi index you can use:
newidx = []
for (n1,n2) in df.columns.ravel():
newidx.append("%s-%s" % (n1,n2))
df.columns=newidx
It will change your dataframe from:
I V
mean std first
V
4200.0 25.499536 31.557133 4200.0
4300.0 25.605662 31.678046 4300.0
4400.0 26.679005 32.919996 4400.0
4500.0 26.786458 32.811633 4500.0

The C++ way of solving conversions (not the classical C) is illustrated with the program below. Note that the intent is to be able to use the same formatting facilities offered by iostream like precision, fill character, padding, hex, and the manipulators, etcetera.
Compile and run this program, then study it. It is simple
#include "iostream"
#include "iomanip"
#include "sstream"
using namespace std;
int main()
{
// Converting the content of a char array or a string to a double variable
double d;
string S;
S = "4.5";
istringstream(S) >> d;
cout << "\nThe value of the double variable d is " << d << endl;
istringstream("9.87654") >> d;
cout << "\nNow the value of the double variable d is " << d << endl;
// Converting a double to string with formatting restrictions
double D=3.771234567;
ostringstream Q;
Q.fill('#');
Q << "<<<" << setprecision(6) << setw(20) << D << ">>>";
S = Q.str(); // formatted converted double is now in string
cout << "\nThe value of the string variable S is " << S << endl;
return 0;
}

First, let's make some test data:
create table client (client_id integer not null primary key auto_increment,
name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
client_id integer references client.id,
cash decimal(10,2),
stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
(1, 10.11, 23.22),
(2, 30.30, 40.40),
(2, 40.40, 50.50);
If you didn't need the portfolio ID, it would be easy:
select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id
+-----------+----------+--------------------+
| client_id | name | max(cash + stocks) |
+-----------+----------+--------------------+
| 1 | John Doe | 33.33 |
| 2 | Jane Doe | 90.90 |
+-----------+----------+--------------------+
Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:
select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id
+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
| 1 | 33.33 |
| 2 | 90.90 |
+-----------+----------+
Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:
select portfolio_id, cash + stocks from portfolio
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
| 5 | 33.33 |
| 6 | 33.33 |
| 8 | 90.90 |
+--------------+---------------+
Finally, we can join to the client table (as you did) in order to include the name of each client:
select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
+-----------+----------+--------------+---------------+
| client_id | name | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
| 1 | John Doe | 5 | 33.33 |
| 1 | John Doe | 6 | 33.33 |
| 2 | Jane Doe | 8 | 90.90 |
+-----------+----------+--------------+---------------+
Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:
select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks
+-----------+----------+--------------+---------------+
| client_id | name | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
| 1 | John Doe | 5 | 33.33 |
| 2 | Jane Doe | 8 | 90.90 |
+-----------+----------+--------------+---------------+
I don't believe the expression is sensical as it is.
Elvis means "if truthy, use the value, else use this other thing."
Your "other thing" is a closure, and the value is status != null
, neither of which would seem to be what you want. If status
is null, Elvis says true
. If it's not, you get an extra layer of closure.
Why can't you just use:
(it.description == desc) && ((status == null) || (it.status == status))
Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find
calls, just use an intermediate variable.

This isn't as easy to do as one might expect -- you can really only do vertical alignment if you know the height of your container. IF this is the case, you can do it with absolute positioning.
The concept is to set the top / left positions at 50%, and then use negative margins (set to half the height / width) to pull the container back to being centered.
Example: http://jsbin.com/ipawe/edit
Basic CSS:
#mydiv {
position: absolute;
top: 50%;
left: 50%;
height: 400px;
width: 700px;
margin-top: -200px; /* -(1/2 height) */
margin-left: -350px; /* -(1/2 width) */
}
mystring.Substring(Math.Max(0, mystring.Length - 4)); //how many lines is this?
If you're positive the length of your string is at least 4, then it's even shorter:
mystring.Substring(mystring.Length - 4);
git reset 'HEAD@{1}'
Git keeps a log of all ref updates (e.g., checkout, reset, commit, merge). You can view it by typing:
git reflog
Somewhere in this list is the commit that you lost. Let's say you just typed git reset HEAD~
and want to undo it. My reflog looks like this:
$ git reflog
3f6db14 HEAD@{0}: HEAD~: updating HEAD
d27924e HEAD@{1}: checkout: moving from d27924e0fe16776f0d0f1ee2933a0334a4787b4c
[...]
The first line says that HEAD
0 positions ago (in other words, the current position) is 3f6db14; it was obtained by resetting to HEAD~
. The second line says that HEAD
1 position ago (in other words, the state before the reset) is d27924e. It was obtained by checking out a particular commit (though that's not important right now). So, to undo the reset, run git reset HEAD@{1}
(or git reset d27924e
).
If, on the other hand, you've run some other commands since then that update HEAD, the commit you want won't be at the top of the list, and you'll need to search through the reflog
.
One final note: It may be easier to look at the reflog
for the specific branch you want to un-reset, say master, rather than HEAD
:
$ git reflog show master
c24138b master@{0}: merge origin/master: Fast-forward
90a2bf9 master@{1}: merge origin/master: Fast-forward
[...]
This should have less noise it in than the general HEAD reflog
.

Choose one from, where :my_date

format:
SELECT EXTRACT(YEAR FROM CAST(:my_date AS DATE));
or
SELECT DATE_PART('year', CAST(:my_date AS DATE));
Better use CAST
than ::
as there may be conflicts with input parameters.
You can use ARG variable defaultValue
and during the run command you can even update this value using --build-arg variable=value
. To use these variables in the docker file you can refer them as $variable
in run command.
Note: These variables would be available for Linux commands like RUN echo $variable
and they wouldn't persist in the image.
To use the hex
encoding in Python 3, use
>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'
In legacy Python, there are several other ways of doing this:
>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'
There is a property of the built-in window.location
object that will provide that for the current window.
// If URL is http://www.somedomain.com/account/search?filter=a#top
window.location.pathname // /account/search
// For reference:
window.location.host // www.somedomain.com (includes port if there is one)
window.location.hostname // www.somedomain.com
window.location.hash // #top
window.location.href // http://www.somedomain.com/account/search?filter=a#top
window.location.port // (empty string)
window.location.protocol // http:
window.location.search // ?filter=a
It turns out that this schema is being standardized as an interface called URLUtils, and guess what? Both the existing window.location
object and anchor elements implement the interface.
So you can use the same properties above for any URL — just create an anchor with the URL and access the properties:
var el = document.createElement('a');
el.href = "http://www.somedomain.com/account/search?filter=a#top";
el.host // www.somedomain.com (includes port if there is one[1])
el.hostname // www.somedomain.com
el.hash // #top
el.href // http://www.somedomain.com/account/search?filter=a#top
el.pathname // /account/search
el.port // (port if there is one[1])
el.protocol // http:
el.search // ?filter=a
[1]: Browser support for the properties that include port is not consistent, See: http://jessepollak.me/chrome-was-wrong-ie-was-right
This works in the latest versions of Chrome and Firefox. I do not have versions of Internet Explorer to test, so please test yourself with the JSFiddle example.
There's also a coming URL
object that will offer this support for URLs themselves, without the anchor element. Looks like no stable browsers support it at this time, but it is said to be coming in Firefox 26. When you think you might have support for it, try it out here.
you can do this as well
$path = "/public";
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach ($objects as $name => $object) {
if ('.' === $object) continue;
if ('..' === $object) continue;
str_replace('/public/', '/', $object->getPathname());
// for example : /public/admin/image.png => /admin/image.png
I'm going to make a bit of an assumption here because I'm not sure. I don't think my MySQL (running on latest 20.04 upgraded) even has a root. I have tried setting one and I remember having problems. I suspect there is not a root user and it will automatically log you in as the MySQL root user if you're logged in as root.
Why do I think this? Because when I do MySQL -u root -p, it will accept any password and log me in as the MySQL root user when I am logged in as root.
I have confirmed that trying that on a non root user doesn't work.
I like this model.
EDIT 2020.12.19: It is no longer a mystery to me why if you are logged in as the root user you get logged into MySQL as the root user. It has to do with the authentication type. Later versions of MySQL are configured with the MySQL plugin 'auth_socket' (maybe you've noticed the /run/mysqld/mysqld.sock file on your system and wondered about it). The plugin uses the SO_PEERCRED option provided by the library auth_socket.so.
You can revert back to password authentication if desired simply by create/update of the password. Showing both ways and options below to make clear.
CREATE USER 'valerie'@'localhost' IDENTIFIED WITH auth_socket;
CREATE USER 'valerie'@'localhost' IDENTIFIED BY 'password';
Yes there is possible to close TCP or UDP port there is a command in DOS

I hope this will work for You
The compiler is already telling you, it's not value
but variable
. You are looking for -Wno-unused-variable
. Also, try g++ --help=warnings
to see a list of available options.
I previously came up with a different workaround that doesn't use stored procedures, but instead uses a parameter table and some connection_id() magic.
EDIT (Copied up from comments)
create a table that contains a column called connection_id
(make it a bigint). Place columns in that table for parameters for the view. Put a primary key on the connection_id
. replace into the parameter table and use CONNECTION_ID()
to populate the connection_id value. In the view use a cross join to the parameter table and put WHERE param_table.connection_id = CONNECTION_ID()
. This will cross join with only one row from the parameter table which is what you want. You can then use the other columns in the where clause for example where orders.order_id = param_table.order_id
.
There is a typo error :
$('#activelist :checkbox')...
Should be :
$('#inactivelist:checkbox')...
Although it's not really clear to me what you're trying to achieve, I spotted an obvious error in your code:
Field.get()
expects the object which contains the field as argument, not some (possible) value of that field. So you should have field.get(object)
.
Since you appear to be looking for the field value, you can obtain that as:
Object objectValue = field.get(object);
No need to instantiate the field type and create some empty/default value; or maybe there's something I missed.
If you want to transpose a matrix like A = np.array([[1,2],[3,4]]), then you can simply use A.T, but for a vector like a = [1,2], a.T does not return a transpose! and you need to use a.reshape(-1, 1), as below
import numpy as np
a = np.array([1,2])
print('a.T not transposing Python!\n','a = ',a,'\n','a.T = ', a.T)
print('Transpose of vector a is: \n',a.reshape(-1, 1))
A = np.array([[1,2],[3,4]])
print('Transpose of matrix A is: \n',A.T)
In my opinion, it would be a cleaner and easier solution to just set a class on the body and set the font-family in css according to that class.
don't know if that's an option in your case though.
Another way is to check the results of
sp_help 'TableName'
(or just highlight the quoted TableName and pres ALT+F1)
With time passing, I just decided to refine my answer. Below is a screenshot of the results that sp_help
provides. A have used the AdventureWorksDW2012 DB for this example. There is numerous good information there, and what we are looking for is at the very end - highlighted in green:
If you are using it in a script, use stat
.
$ date | tee /tmp/foo
Wed Mar 13 05:36:31 UTC 2019
$ stat -c %s /tmp/foo
29
$ ls -l /tmp/foo
-rw-r--r-- 1 bruno wheel 29 Mar 13 05:36 /tmp/foo
That will give you size in bytes. See man stat
for more output format options.
The OSX/BSD equivalent is:
$ date | tee /tmp/foo
Wed Mar 13 00:54:16 EDT 2019
$ stat -f %z /tmp/foo
29
$ ls -l /tmp/foo
-rw-r--r-- 1 bruno wheel 29 Mar 13 00:54 /tmp/foo
Use EXPLAIN to see how your database executes the query on your data. There is a huge "it depends" in this answer...
PostgreSQL can rewrite a subquery to a join or a join to a subquery when it thinks one is faster than the other. It all depends on the data, indexes, correlation, amount of data, query, etc.
I implemented some code to do it manually:
using System.Security.Principal;
public bool IsUserAdministrator()
{
bool isAdmin;
try
{
WindowsIdentity user = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(user);
isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
}
catch (UnauthorizedAccessException ex)
{
isAdmin = false;
}
catch (Exception ex)
{
isAdmin = false;
}
return isAdmin;
}
My guess would be to check that the mysqli extension is enabled in your PHP configuration. More info would be great (eg. OS, AMP stack, etc.).
Check in your php.ini configuration for mysqli and make sure there is no ';' in front of the extension. The one enabled on my setup is php_mysqli_libmysql.dll.
Use PowerShell to create your event log and source:
New-EventLog -LogName MyApplicationLog `
-Source MySource `
-MessageResourceFile C:\windows\Microsoft.NET\Framework\v4.0.30319\EventLogMessages.dll
You'll need the messages dll to avoid the problem you are seeing.
To build an image from command-line in windows/linux. 1. Create a docker file in your current directory. eg: FROM ubuntu RUN apt-get update RUN apt-get -y install apache2 ADD . /var/www/html ENTRYPOINT apachectl -D FOREGROUND ENV name Devops_Docker 2. Don't save it with .txt extension. 3. Under command-line run the command docker build . -t apache2image
Perhaps not the most efficient solution, but certainly short & simple:
def repstr(string, length):
return (string * length)[0:length]
repstr("foobar", 14)
Gives "foobarfoobarfo". One thing about this version is that if length < len(string) then the output string will be truncated. For example:
repstr("foobar", 3)
Gives "foo".
Edit: actually to my surprise, this is faster than the currently accepted solution (the 'repeat_to_length' function), at least on short strings:
from timeit import Timer
t1 = Timer("repstr('foofoo', 30)", 'from __main__ import repstr')
t2 = Timer("repeat_to_length('foofoo', 30)", 'from __main__ import repeat_to_length')
t1.timeit() # gives ~0.35 secs
t2.timeit() # gives ~0.43 secs
Presumably if the string was long, or length was very high (that is, if the wastefulness of the string * length
part was high) then it would perform poorly. And in fact we can modify the above to verify this:
from timeit import Timer
t1 = Timer("repstr('foofoo' * 10, 3000)", 'from __main__ import repstr')
t2 = Timer("repeat_to_length('foofoo' * 10, 3000)", 'from __main__ import repeat_to_length')
t1.timeit() # gives ~18.85 secs
t2.timeit() # gives ~1.13 secs

Hy there , in my case i am using asp.net development environment, so i was want to upload those data in asynchronus ajax request , in [webMethod] you can not catch the file uploader since it is not static element , so i had to make a turnover for such solution by fixing the path , than convert the wanted image into bytes to save it in DB .
Here is my javascript function , hope it helps you:
function FixPath(Path)
{
var HiddenPath = Path.toString();
alert(HiddenPath.indexOf("FakePath"));
if (HiddenPath.indexOf("FakePath") > 1)
{
var UnwantedLength = HiddenPath.indexOf("FakePath") + 7;
MainStringLength = HiddenPath.length - UnwantedLength;
var thisArray =[];
var i = 0;
var FinalString= "";
while (i < MainStringLength)
{
thisArray[i] = HiddenPath[UnwantedLength + i + 1];
i++;
}
var j = 0;
while (j < MainStringLength-1)
{
if (thisArray[j] != ",")
{
FinalString += thisArray[j];
}
j++;
}
FinalString = "~" + FinalString;
alert(FinalString);
return FinalString;
}
else
{
return HiddenPath;
}
}
here only for testing :
$(document).ready(function () {
FixPath("hakounaMatata:/7ekmaTa3mahaLaziz/FakePath/EnsaLmadiLiYghiz");
});
// this will give you : ~/EnsaLmadiLiYghiz
numpy has a great tool for this task ("numpy.reshape") link to reshape documentation
a = [[ 0 1]
[ 2 3]
[ 4 5]
[ 6 7]
[ 8 9]
[10 11]
[12 13]
[14 15]
[16 17]]
`numpy.reshape(a,(3,3))`
you can also use the "-1" trick
`a = a.reshape(-1,3)`
the "-1" is a wild card that will let the numpy algorithm decide on the number to input when the second dimension is 3
so yes.. this would also work:
a = a.reshape(3,-1)
and this:
a = a.reshape(-1,2)
would do nothing
and this:
a = a.reshape(-1,9)
would change the shape to (2,9)
problem in %time:~0,2%
can't set to 24 hrs format, ended with space(1-9), instead of 0(1-9)
go around with:
set HR=%time:~0,2%
set HR=%Hr: =0% (replace space with 0 if any <has a space in between : =0>)
then replace %time:~0,2%
with %HR%
good luck
There's a few things with your code as it stands:
The first thing we are going to do is to declare your variable as let
, as we are not going to modify it later.
let catPictureURL = URL(string: "http://i.imgur.com/w5rkSIj.jpg")! // We can force unwrap because we are 100% certain the constructor will not return nil in this case.
Then we need to download the contents of that URL. We can do this with the URLSession
object. When the completion handler is called, we will have a UIImage
downloaded from the web.
// Creating a session object with the default configuration.
// You can read more about it here https://developer.apple.com/reference/foundation/urlsessionconfiguration
let session = URLSession(configuration: .default)
// Define a download task. The download task will download the contents of the URL as a Data object and then you can do what you wish with that data.
let downloadPicTask = session.dataTask(with: catPictureURL) { (data, response, error) in
// The download has finished.
if let e = error {
print("Error downloading cat picture: \(e)")
} else {
// No errors found.
// It would be weird if we didn't have a response, so check for that too.
if let res = response as? HTTPURLResponse {
print("Downloaded cat picture with response code \(res.statusCode)")
if let imageData = data {
// Finally convert that Data into an image and do what you wish with it.
let image = UIImage(data: imageData)
// Do something with your image.
} else {
print("Couldn't get image: Image is nil")
}
} else {
print("Couldn't get response code for some reason")
}
}
}
Finally you need to call resume
on the download task, otherwise your task will never start:
downloadPicTask.resume()
.
All this code may look a bit intimidating at first, but the URLSession
APIs are block based so they can work asynchronously - If you block your UI thread for a few seconds, the OS will kill your app.
Your full code should look like this:
let catPictureURL = URL(string: "http://i.imgur.com/w5rkSIj.jpg")!
// Creating a session object with the default configuration.
// You can read more about it here https://developer.apple.com/reference/foundation/urlsessionconfiguration
let session = URLSession(configuration: .default)
// Define a download task. The download task will download the contents of the URL as a Data object and then you can do what you wish with that data.
let downloadPicTask = session.dataTask(with: catPictureURL) { (data, response, error) in
// The download has finished.
if let e = error {
print("Error downloading cat picture: \(e)")
} else {
// No errors found.
// It would be weird if we didn't have a response, so check for that too.
if let res = response as? HTTPURLResponse {
print("Downloaded cat picture with response code \(res.statusCode)")
if let imageData = data {
// Finally convert that Data into an image and do what you wish with it.
let image = UIImage(data: imageData)
// Do something with your image.
} else {
print("Couldn't get image: Image is nil")
}
} else {
print("Couldn't get response code for some reason")
}
}
}
downloadPicTask.resume()
You can use ng-change instead of ng-click:
<!doctype html>
<html>
<head>
<script src="http://code.angularjs.org/1.2.3/angular.min.js"></script>
<script>
var app = angular.module('myapp', []);
app.controller('mainController', function($scope) {
$scope.vm = {};
$scope.vm.myClick = function($event) {
alert($event);
}
});
</script>
</head>
<body ng-app="myapp">
<div ng-controller="mainController">
<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
</div>
</body>
</html>
I just had to do this myself, so I thought I would post another answer here.
Here is another way to create a rounded corner border and clip its inner content. This is the straightforward way by using the Clip property. It's nice if you want to avoid a VisualBrush.
The xaml:
<Border
Width="200"
Height="25"
CornerRadius="11"
Background="#FF919194"
>
<Border.Clip>
<RectangleGeometry
RadiusX="{Binding CornerRadius.TopLeft, RelativeSource={RelativeSource AncestorType={x:Type Border}}}"
RadiusY="{Binding RadiusX, RelativeSource={RelativeSource Self}}"
>
<RectangleGeometry.Rect>
<MultiBinding
Converter="{StaticResource widthAndHeightToRectConverter}"
>
<Binding
Path="ActualWidth"
RelativeSource="{RelativeSource AncestorType={x:Type Border}}"
/>
<Binding
Path="ActualHeight"
RelativeSource="{RelativeSource AncestorType={x:Type Border}}"
/>
</MultiBinding>
</RectangleGeometry.Rect>
</RectangleGeometry>
</Border.Clip>
<Rectangle
Width="100"
Height="100"
Fill="Blue"
HorizontalAlignment="Left"
VerticalAlignment="Center"
/>
</Border>
The code for the converter:
public class WidthAndHeightToRectConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
double width = (double)values[0];
double height = (double)values[1];
return new Rect(0, 0, width, height);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
So far, I made a solution using Ruby. Place this inside the Product model:
#return first of matching products (id only to minimize memory consumption)
def self.custom_find_by_name(product_name)
@@product_names ||= Product.all(:select=>'id, name')
@@product_names.select{|p| p.name.downcase == product_name.downcase}.first
end
#remember a way to flush finder cache in case you run this from console
def self.flush_custom_finder_cache!
@@product_names = nil
end
This will give me the first product where names match. Or nil.
>> Product.create(:name => "Blue jeans")
=> #<Product id: 303, name: "Blue jeans">
>> Product.custom_find_by_name("Blue Jeans")
=> nil
>> Product.flush_custom_finder_cache!
=> nil
>> Product.custom_find_by_name("Blue Jeans")
=> #<Product id: 303, name: "Blue jeans">
>>
>> #SUCCESS! I found you :)
The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.
The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.
Reminder
SQL Server only allows one table to have IDENTITY_INSERT property set to ON.
This does not work:
SET IDENTITY_INSERT TableA ON
SET IDENTITY_INSERT TableB ON
... INSERT ON TableA ...
... INSERT ON TableB ...
SET IDENTITY_INSERT TableA OFF
SET IDENTITY_INSERT TableB OFF
Instead:
SET IDENTITY_INSERT TableA ON
... INSERT ON TableA ...
SET IDENTITY_INSERT TableA OFF
SET IDENTITY_INSERT TableB ON
... INSERT ON TableB ...
SET IDENTITY_INSERT TableB OFF
np.fromfile()
has a sep=
keyword argument:
Separator between items if file is a text file. Empty (“”) separator means the file should be treated as binary. Spaces (” ”) in the separator match zero or more whitespace characters. A separator consisting only of spaces must match at least one whitespace.
The default value of sep=""
means that np.fromfile()
tries to read it as a binary file rather than a space-separated text file, so you get nonsense values back. If you use np.fromfile('markers.txt', sep=" ")
you will get the result you are looking for.
However, as others have pointed out, np.loadtxt()
is the preferred way to convert text files to numpy arrays, and unless the file needs to be human-readable it is usually better to use binary formats instead (e.g. np.load()
/np.save()
).
dataframe['column'].squeeze()
should solve this. It basically changes the dataframe column to a list.
If you encounter this problem and UI Controls were created on a separate worker thread when working with BitmapSource

does not work in such instances
From the python command prompt:

Your server needs to have the php modules installed so it can parse php code.
If you are on ubuntu you can do this easily with
sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart
Otherwise you may compile apache with php: http://dan.drydog.com/apache2php.html
Specifying your server OS will help others to answer more specifically.
I found the I could get around this problem by changing the target location from obj/[release|stage|..] to a new path outside of the solution folders completely eg c:\deployment. It seems like VS 2012 was getting confused and maybe giving up somewhere during the publish process.

Have you seen the book "Bioinformatics Programming using Python"? Looks like you're an exact member of its focus group.
@dannyeuu's answer is correct. pd.concat naturally does a join on index columns, if you set the axis option to 1. The default is an outer join, but you can specify inner join too. Here is an example:
x = pd.DataFrame({'a': [2,4,3,4,5,2,3,4,2,5], 'b':[2,3,4,1,6,6,5,2,4,2], 'val': [1,4,4,3,6,4,3,6,5,7], 'val2': [2,4,1,6,4,2,8,6,3,9]})
x.set_index(['a','b'], inplace=True)
x.sort_index(inplace=True)
y = x.__deepcopy__()
y.loc[(14,14),:] = [3,1]
y['other']=range(0,11)
y.sort_values('val', inplace=True)
z = x.__deepcopy__()
z.loc[(15,15),:] = [3,4]
z['another']=range(0,22,2)
z.sort_values('val2',inplace=True)
pd.concat([x,y,z],axis=1)
Very simply, a delegate provides functionality for how a function pointer SHOULD work. There are many limitations of function pointers in C++. A delegate uses some behind-the-scenes template nastyness to create a template-class function-pointer-type-thing that works in the way you might want it to.
ie - you can set them to point at a given function and you can pass them around and call them whenever and wherever you like.
There are some very good examples here:
System.Reflection.Assembly.GetEntryAssembly().Location;
One small point to Andy Hayden's solution – it doesn't work (anymore?) because np.nan == np.nan
yields False
, so the replace
function doesn't actually do anything.
What worked for me was this:
df['b'] = df['b'].apply(lambda x: x if not np.isnan(x) else -1)
(At least that's the behavior for Pandas 0.19.2. Sorry to add it as a different answer, I do not have enough reputation to comment.)
Instantiate a new ArrayList:
List<String> myList = new ArrayList<String>();
Iterate over your data structure (with a for loop, for instance, more details on your code would help.) and for each element (yourElement):
myList.add(yourElement);
Edit:
Sorry i forgot about pluck()
as many have commented :
Easiest way is :
return DB::table('users')->where('username', $username)->pluck('groupName');
Which will directly return the only the first result for the requested row as a string.
Using the fluent query builder you will obtain an array anyway. I mean The Query Builder has no idea how many rows will come back from that query. Here is what you can do to do it a bit cleaner
$result = DB::table('users')->select('groupName')->where('username', $username)->first();
The first()
tells the queryBuilder to return only one row so no array, so you can do :
return $result->groupName;
Hope it helps
The right way to change directory or run from multiple directories under different port for Apache 2 is as follows:
For Apache 2, the configuration files are located under /etc/apache2
and doesn’t use a single configuration file as in older versions but is split into smaller configuration files, with /etc/apache2/apache2.conf
being the main configuration file. To serve files from a different directory we need a new virtualhost conf file. The virtualhost configuration files are located in /etc/apache2/sites-available
(do not edit files within sites-enabled). The default Apache installation uses virtualhost conf file 000-default.conf
.
Start by creating a new virtualhost file by copying the default virtualhost file used by the default installation of Apache (the one that runs at localhost on port 80). Change into directory /etc/apache2/sites-available
and then make copy by sudo cp 000-default.conf example.com.conf
, now edit the file by sudo gedit example.com.conf
to:
<VirtualHost *:80>
ServerAdmin example@localhost
DocumentRoot /home/ubuntu/example.com
</VirtualHost>
I have deleted the nonimportant lines from the above file for brevity. Here DocumentRoot
is the path to the directory from which the website files are to be served such as index.html
.
Create the directory from which you want to serve the files, for example, mkdir example.com
and change owner and default group of the directory, for example, if your logged in user name is ubuntu
change permissions as sudo chown ubuntu:www-data example.com
. This grants full access to the user ubuntu
and allows read and execute access to the group www-data
.
Now edit the Apache configuration file /etc/apache2/apache2.conf
by issuing command sudo gedit apache2.conf
and find the line <Directory /var/www/>
and below the closing tag </Directory>
, add the following below:
<Directory /home/ubuntu/example.com>
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Require all granted
</Directory>
Now there are two commands to enable or disable the virtualhost configuration files, which are a2ensite
and a2dissite
respectively. Now since our example.com.conf
file uses the same port(80
) as used by the default configuration file(000-default.conf
), we have to disable the default configuration file by issuing the command sudo a2dissite 000-default.conf
and enable our virtualhost configuration file by sudo a2ensite example.com.conf
Now restart or reload the server with command sudo service apache2 restart
. Now Apache serves files from directory example.com
at localhost
on default port of 80
.
The a2ensite
command basically creates a symbolic link to the configuration file under the site-enabled directory.
Do not edit files within sites-enabled (or *-enabled) directory, as pointed out in this answer.
Now if you need to run the directory on a different port, change the port number from 80 to 8080 by editing the virtualhost file as:
<VirtualHost *:8080>
ServerAdmin user@localhost
DocumentRoot /home/ubuntu/work
</VirtualHost>
and editing /etc/apache2/ports.conf
and adding Listen 8080
just below the line Listen 80
Now we can enable the default virtualhost configuration file that runs on port 80 since example.com directory uses port 8080, as sudo a2ensite 000-default.conf
.
Now restart or reload the server with command sudo service apache2 restart
. Now both the directories can be accessed from localhost
and localhost:8080
.
I think you missed a equal sign at:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);
Change to:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null);
String logStringVal= date+"";
Can convert the long into string object, cool shortcut for converting into string...but use of String.valueOf(date);
is advisable
For me the sexier solution is to construct a dynamic associative array & use it
// A dirty array sent by user
$dirtyArray = ['Cecile', 'Gilles', 'Andre', 'Claude'];
// we construct an associative array like this
// [ ':name_0' => 'Cecile', ... , ':name_3' => 'Claude' ]
$params = array_combine(
array_map(
// construct param name according to array index
function ($v) {return ":name_{$v}";},
// get values of users
array_keys($dirtyArray)
),
$dirtyArray
);
// construct the query like `.. WHERE name IN ( :name_1, .. , :name_3 )`
$query = "SELECT * FROM user WHERE name IN( " . implode(",", array_keys($params)) . " )";
// here we go
$stmt = $db->prepare($query);
$stmt->execute($params);
Doesn't have to be; "64-bit machine" can mean many things, but typically means that the CPU has registers that big. The sizeof a type is determined by the compiler, which doesn't have to have anything to do with the actual hardware (though it typically does); in fact, different compilers on the same machine can have different values for these.
If you can use inline styling, you can set the left and right padding on each td
.. Or you use an extra td
between columns and set a number of non-breaking spaces as @rene kindly suggested.
Both are pretty ugly ;p css ftw

What worked for me was to change my WHERE clause into a SELECT subquery
FROM:
DELETE FROM CommentTag WHERE [dbo].CommentTag.NoteId = [dbo].FetchedTagTransferData.IssueId
TO:
DELETE FROM CommentTag WHERE [dbo].CommentTag.NoteId = (SELECT NoteId FROM FetchedTagTransferData)
What you have here is a non-local variable (https://en.wikipedia.org/wiki/Non-local_variable), i.e. you access a local variable in a method an anonymous class.
Local variables of the method are kept on the stack and lost as soon as the method ends, however even after the method ends, the local inner class object is still alive on the heap and will need to access this variable (here, when an action is performed).
I would suggest two workarounds :
Either you make your own class that implements actionlistenner
and takes as constructor argument, your variable and keeps it as an class attribute. Therefore you would only access this variable within the same object.
Or (and this is probably the best solution) just qualify a copy of the variable final
to access it in the inner scope as the error suggests to make it a constant:
This would suit your case since you are not modifying the value of the variable.
For cases where you also wish to have the option of setting 'b' to None:
def p(self, **kwargs):
b = kwargs.get('b', self.a)
print b
I had a similar problem (differences being I wanted to return an object that was already converted to a json string and my controller get returns a IHttpActionResult)
Here is how I solved it. First I declared a utility class
public class RawJsonActionResult : IHttpActionResult
{
private readonly string _jsonString;
public RawJsonActionResult(string jsonString)
{
_jsonString = jsonString;
}
public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
{
var content = new StringContent(_jsonString);
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var response = new HttpResponseMessage(HttpStatusCode.OK) { Content = content };
return Task.FromResult(response);
}
}
This class can then be used in your controller. Here is a simple example
public IHttpActionResult Get()
{
var jsonString = "{\"id\":1,\"name\":\"a small object\" }";
return new RawJsonActionResult(jsonString);
}
Since Docker 1.5 you can now expose a range of ports to other linked containers using:
The Dockerfile EXPOSE command:
EXPOSE 7000-8000
or The Docker run command:
docker run --expose=7000-8000
Or instead you can publish a range of ports to the host machine via Docker run command:
docker run -p 7000-8000:7000-8000

Many programming language optimize the switch statement so that it is much faster than a standard if-else if structure provided the cases are compiler constants. Many languages use a jump table or indexed branch table to optimize switch statements. Wikipedia has a good discussion of the switch statement. Also, here is a discussion of switch optimization in C.
One thing to note is that switch statements can be abused and, depending on the case, it may be preferable to use polymorphism instead of switch statements. See here for an example.

[1] "0.2500000000"
specifies that you want to format a floating point number with ten decimal points (in %.10f
the f
is for float and the .10
specifies ten decimal points).
I don't know of any way of forcing R's higher level functions to print an exact number of digits.
Displaying 100 digits does not make sense if you are printing R's usual numbers, since the best accuracy you can get using 64-bit doubles is around 16 decimal digits (look at .Machine$double.eps on your system). The remaining digits will just be junk.
Using a CTE generated numbers table to examine each character, then FOR XML to concat to a string of kept values you can...
CREATE FUNCTION [dbo].[PatRemove](
@pattern varchar(50),
@expression varchar(8000)
)
RETURNS varchar(8000)
AS
BEGIN
WITH
d(d) AS (SELECT d FROM (VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) digits(d)),
nums(n) AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM d d1, d d2, d d3, d d4),
chars(c) AS (SELECT SUBSTRING(@expression, n, 1) FROM nums WHERE n <= LEN(@expression))
SELECT
@expression = (SELECT c AS [text()] FROM chars WHERE c NOT LIKE @pattern FOR XML PATH(''));
RETURN @expression;
END
