Note in 2018: readAsBinaryString
is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer
(or in some cases, readAsDataURL
) instead.
readAsBinaryString
says that the data must be represented as a binary string, where:
...every byte is represented by an integer in the range [0..255].
JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)
If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).
If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText
and readAsBinaryString
, but with readAsBinaryString
you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText
, because readAsText
will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.
You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-type" content="text/html;charset=UTF-8">
<title>Show File Data</title>
<style type='text/css'>
body {
font-family: sans-serif;
}
</style>
<script type='text/javascript'>
function loadFile() {
var input, file, fr;
if (typeof window.FileReader !== 'function') {
bodyAppend("p", "The file API isn't supported on this browser yet.");
return;
}
input = document.getElementById('fileinput');
if (!input) {
bodyAppend("p", "Um, couldn't find the fileinput element.");
}
else if (!input.files) {
bodyAppend("p", "This browser doesn't seem to support the `files` property of file inputs.");
}
else if (!input.files[0]) {
bodyAppend("p", "Please select a file before clicking 'Load'");
}
else {
file = input.files[0];
fr = new FileReader();
fr.onload = receivedText;
fr.readAsText(file);
}
function receivedText() {
showResult(fr, "Text");
fr = new FileReader();
fr.onload = receivedBinary;
fr.readAsBinaryString(file);
}
function receivedBinary() {
showResult(fr, "Binary");
}
}
function showResult(fr, label) {
var markup, result, n, aByte, byteStr;
markup = [];
result = fr.result;
for (n = 0; n < result.length; ++n) {
aByte = result.charCodeAt(n);
byteStr = aByte.toString(16);
if (byteStr.length < 2) {
byteStr = "0" + byteStr;
}
markup.push(byteStr);
}
bodyAppend("p", label + " (" + result.length + "):");
bodyAppend("pre", markup.join(" "));
}
function bodyAppend(tagName, innerHTML) {
var elm;
elm = document.createElement(tagName);
elm.innerHTML = innerHTML;
document.body.appendChild(elm);
}
</script>
</head>
<body>
<form action='#' onsubmit="return false;">
<input type='file' id='fileinput'>
<input type='button' id='btnLoad' value='Load' onclick='loadFile();'>
</form>
</body>
</html>
If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:
Text (13): 54 65 73 74 69 6e 67 20 31 20 32 20 33 Binary (28): ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00
As you can see, readAsText
interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString
didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).
* XMLHttpRequest.response with responseType = "arraybuffer"
is supported in HTML 5.
** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.
update 3
Issue 2451 is fixed in Angular 4.0.0
See also
update 2
This isn't supported.
There are template variables but it's not supported to assign arbitrary values. They can only be used to refer to the elements they are applied to, exported names of directives or components and scope variables for structural directives like ngFor
,
See also https://github.com/angular/angular/issues/2451
Update 1
@Directive({
selector: '[var]',
exportAs: 'var'
})
class VarDirective {
@Input() var:any;
}
and initialize it like
<div #aVariable="var" var="abc"></div>
or
<div #aVariable="var" [var]="'abc'"></div>
and use the variable like
<div>{{aVariable.var}}</div>
(not tested)
#aVariable
creates a reference to the VarDirective
(exportAs: 'var'
)var="abc"
instantiates the VarDirective
and passes the string value "abc"
to it's value input.aVariable.var
reads the value assigned to the var
directives var
input.Here is an example that works on Chrome 5.0.375.125.
The page B (iframe content):
<html>
<head></head>
<body>
<script>
top.postMessage('hello', 'A');
</script>
</body>
</html>
Note the use of top.postMessage
or parent.postMessage
not window.postMessage
here
The page A:
<html>
<head></head>
<body>
<iframe src="B"></iframe>
<script>
window.addEventListener( "message",
function (e) {
if(e.origin !== 'B'){ return; }
alert(e.data);
},
false);
</script>
</body>
</html>
A and B must be something like http://domain.com
EDIT:
From another question, it looks the domains(A and B here) must have a /
for the postMessage
to work properly.
In Angular you can use directives to prevent zooming on focus on IOS devices. No meta tag to preserve accessibility.
import { Directive, ElementRef, HostListener } from '@angular/core';
const MINIMAL_FONT_SIZE_BEFORE_ZOOMING_IN_PX = 16;
@Directive({ selector: '[noZoomiOS]' })
export class NoZoomiOSDirective {
constructor(private el: ElementRef) {}
@HostListener('focus')
onFocus() {
this.setFontSize('');
}
@HostListener('mousedown')
onMouseDown() {
this.setFontSize(`${MINIMAL_FONT_SIZE_BEFORE_ZOOMING_IN_PX}px`);
}
private setFontSize(size: string) {
const { fontSize: currentInputFontSize } = window.getComputedStyle(this.el.nativeElement, null);
if (MINIMAL_FONT_SIZE_BEFORE_ZOOMING_IN_PX <= +currentInputFontSize.match(/\d+/)) {
return;
}
const iOS = navigator.platform && /iPad|iPhone|iPod/.test(navigator.platform);
iOS
&& (this.el.nativeElement.style.fontSize = size);
}
}
You can use it like this <input noZoomiOS >
after you declare it in your *.module.ts
For text type use autocomplete="off"
or autocomplete="false"
<input id="username" type="text" autocomplete="false">
For password type use autocomplete="new-password"
<input id="password" type="password" autocomplete="new-password">
A simple solution with minimal javascript is to use the html attribute pattern (supported by most modern browsers). This works by setting the pattern of the second field to the value of the first field.
Unfortunately, you also need to escape the regex, for which no standard function exists.
<form>
<input type="text" oninput="form.confirm.pattern = escapeRegExp(this.value)">
<input name="confirm" pattern="" title="Fields must match" required>
</form>
<script>
function escapeRegExp(str) {
return str.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");
}
</script>
The only way I can get firefox, edge, and Internet explorer to turn off autocomplete is to add autocomplete="false" in my form statement like:
<form action="postingpage.php" autocomplete="false" method="post">
and I have to add the autocomplete="off" to my form input and change the type to text Like:
<input type="text" autocomplete="off">
It seems that this html code needs to be standardized with the browsers. the form type = password should be revised so that it overrides browser settings. The only issue I have is that I lost my input masking. But on the bright side the annoying "this site is not secure" is not showing up in firefox.
for me, its not a big deal since the user is already authenticated and its my change user name and password portion of it
You can set the z-index in css
<div style="z-index: -1"></div>
jQuery("select#cboDays option[value='Wednesday']").attr("selected", "selected");
For normal form you can do
class MyModelForm(forms.ModelForm):
slug = forms.CharField(widget=forms.HiddenInput())
If you have model form you can do the following
class MyModelForm(forms.ModelForm):
class Meta:
model = TagStatus
fields = ('slug', 'ext')
widgets = {'slug': forms.HiddenInput()}
You can also override __init__
method
class Myform(forms.Form):
def __init__(self, *args, **kwargs):
super(Myform, self).__init__(*args, **kwargs)
self.fields['slug'].widget = forms.HiddenInput()
Only this worked for me:
#container:hover .cube { background-color: yellow; }
Where .cube
is CssClass of the #cube
.
Tested in Firefox, Chrome and Edge.
here is a small snippet that might be cool to try out:
input {
border-radius: 10px;
border-color: violet;
border-style: solid;
}
note that: border-style
removes the inner shadow.
input {_x000D_
border-radius: 10px;_x000D_
border-color: violet;_x000D_
border-style: solid;_x000D_
}
_x000D_
<input type="text"/>
_x000D_
you can use ES6 back quits
var inputs = [_x000D_
`<input type='checkbox' id='chbox0' onclick='checkboxChecked(this);'> <input type='text' class='noteinputs0'id='note` + 0 + `' placeholder='task0'><button id='notebtn0' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 1 + `' placeholder='task1'><button class='notebuttons' id='notebtn1' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 2 + `' placeholder='task2'><button class='notebuttons' id='notebtn2' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 3 + `' placeholder='task3'><button class='notebuttons' id='notebtn3' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 4 + `' placeholder='task4'><button class='notebuttons' id='notebtn4' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 5 + `' placeholder='task5'><button class='notebuttons' id='notebtn5' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 6 + `' placeholder='task6'><button class='notebuttons' id='notebtn6' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 7 + `' placeholder='task7'><button class='notebuttons' id='notebtn7' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 8 + `' placeholder='task8'><button class='notebuttons' id='notebtn8' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 9 + `' placeholder='task9'><button class='notebuttons' id='notebtn9' >creat</button>`_x000D_
].sort().join(" ");_x000D_
document.querySelector('#hi').innerHTML += `<br>` +inputs;
_x000D_
<div id="hi"></div>

There are two basic ways:
url(../../images/image.png)
or
url(/Web/images/image.png)
I prefer the latter, as it's easier to work with and works from all locations in the site (so useful for inline image paths too).
Mind you, I wouldn't do so much deep nesting of folders. It seems unnecessary and makes life a bit difficult, as you've found.
You can use the HttpWebRequest class to do so.
Example here:
using System;
using System.Net;
using System.Text;
using System.IO;
public class Test
{
// Specify the URL to receive the request.
public static void Main (string[] args)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);
// Set some reasonable limits on resources used by this request
request.MaximumAutomaticRedirections = 4;
request.MaximumResponseHeadersLength = 4;
// Set credentials to use for this request.
request.Credentials = CredentialCache.DefaultCredentials;
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
Console.WriteLine ("Content length is {0}", response.ContentLength);
Console.WriteLine ("Content type is {0}", response.ContentType);
// Get the stream associated with the response.
Stream receiveStream = response.GetResponseStream ();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);
Console.WriteLine ("Response stream received.");
Console.WriteLine (readStream.ReadToEnd ());
response.Close ();
readStream.Close ();
}
}
/*
The output from this example will vary depending on the value passed into Main
but will be similar to the following:
Content length is 1542
Content type is text/html; charset=utf-8
Response stream received.
<html>
...
</html>
*/
Did you remember setting the height of the html and body tags in your CSS? This is generally how I've gotten DIVs to extend to full height:
<html>
<head>
<style type="text/css">
html,body { height: 100%; margin: 0px; padding: 0px; }
#full { background: #0f0; height: 100% }
</style>
</head>
<body>
<div id="full">
</div>
</body>
</html>
If you just want to give users using a MS browser a warning or something, this code should be good.
HTML:
<p id="IE">You are not using a microsoft browser</p>
Javascript:
using_ms_browser = navigator.appName == 'Microsoft Internet Explorer' || (navigator.appName == "Netscape" && navigator.appVersion.indexOf('Edge') > -1) || (navigator.appName == "Netscape" && navigator.appVersion.indexOf('Trident') > -1);
if (using_ms_browser == true){
document.getElementById('IE').innerHTML = "You are using a MS browser"
}
Thanks to @GavinoGrifoni
There's a workaround for IE - use inline SVG and set pointer-events="none" in SVG. See my answer in How to make Internet Explorer emulate pointer-events:none?
The value
attribute on submit
-type <input>
elements controls the text displayed.
<input type="submit" class="like" value="Like" />
You can use it like this, I hope you wont get outdated message now.
<td valign="top" style="white-space:nowrap" width="237">
As pointed by @ThiefMaster it is recommended to put width
and valign to CSS (note: CSS calls it vertical-align
).
1)
<td style="white-space:nowrap; width:237px; vertical-align:top;">
2) We can make a CSS class like this, it is more elegant way
In style section
.td-some-name
{
white-space:nowrap;
width:237px;
vertical-align:top;
}
In HTML section
<td class="td-some-name">
If your margin is set on the body, then setting the background color of the html tag should color the margin area
html { background-color: black; }
body { margin:50px; background-color: white; }
Or as dmackerman suggestions, set a margin of 0, but a border of the size you want the margin to be and set the border-color
<div style="float: left;margin-right:10px">
<table>
<tr>
<td>..</td>
</tr>
</table>
</div>
<div style="float: left">
<table>
<tr>
<td>..</td>
</tr>
</table>
</div>
if none of those solutions didn't work for you, try adding after
.trigger( "change" );
ex.
$("#baba").val("").trigger( "change" );
or
$("#baba").val(false).trigger( "change" );
or
$("#baba option").prop("selected", false).trigger( "change" );
or
$('#baba').prop('selectedIndex',-1).trigger( "change" );
or
$('#baba option:first').prop('selected',true).trigger( "change" );
You can't send email using javascript or html. You need server side scripts in php or other technologies to send email.
You can also "fix" this by replacing the image with its inline Base64 representation:
Useful, when you do not intend to publish the page on the web, but instead use it on local machines only. img.src= "data:image/gif;base64,R0lGODlhCwALAIAAAAAA3pn/ZiH5BAEAAAEALAAAAAALAAsAAAIUhA+hkcuO4lmNVindo7qyrIXiGBYAOw==";
Another solution, using jQuery:
$(document).ready(function() {
$("input").keypress(function(e) {
if (e.which == 13) {
$('#submit').click();
return false;
}
return true;
});
});
This should work on the following forms, making "Update" the default action:
<form name="f" method="post" action="/action">
<input type="text" name="text1" />
<input type="submit" name="button2" value="Delete" />
<input type="submit" name="button1" id="submit" value="Update" />
</form>
As well as:
<form name="f" method="post" action="/action">
<input type="text" name="text1" />
<button type="submit" name="button2">Delete</button>
<button type="submit" name="button1" id="submit">Update</button>
</form>
This traps the Enter key only when an input field on the form has focus.
Have you thought about using the TAG "dt" instead of "ul" for nesting lists? It's inherit style and structure allow you to have a title per section and it automatically tabulates the content that goes inside.
<dl>
<dt>Coffee</dt>
<dd>Black hot drink</dd>
<dt>Milk</dt>
<dd>White cold drink</dd>
</dl>
VS
<ul>
<li>Choice A</li>
<li>Choice B
<ul>
<li>Sub 1</li>
<li>Sub 2</li>
</ul>
</li>
</ul>
For mac OS you should use this :
body {
background: url(../../img/bg.png);
}
The most simple what I've found to get the XPath for a particular Element is to install FireBug extension for Firefox go to the site/webpage press F12 to bring up firebug; right select and right click the element on the page that you want to query and select "Inspect Element" Firebug will select the element in its IDE then right click the Element in Firebug and choose "Copy XPath" this function will give you the exact XPath Query you need to get the element you want using HTML Agility Library.
Somehow I fiddled around and some how I got it to work:
<iframe src="http://www.example.com#inside" width="100%" height="100%" align="center" ></iframe>
I think this is the first time this code has been posted so share it
Just find the remainder by dividing by 1, that is x%1. If the remainder is 0, it means that x is a whole number. Otherwise, you have to display the message "Must input numbers". This will work even in the case of strings, decimal numbers etc.
function checkInp()
{
var x = document.forms["myForm"]["age"].value;
if ((x%1) != 0)
{
alert("Must input numbers");
return false;
}
}
In case you're here wondering how this works for Material UI when building in React, here's how you add this to your <TableHead>
Component:
<TableHead style={{ whiteSpace: 'nowrap'}}>
Get at number:
window.getComputedStyle( *Element* , null).getPropertyValue( *CSS* );
Example:
window.getComputedStyle( document.body ,null).getPropertyValue('background-color');
window.getComputedStyle( document.body ,null).getPropertyValue('width');
~ document.body.clientWidth
You could make use of the Javascript DOM API. In particular, look at the createElement() method.
You could create a re-usable function that will create an image like so...
function show_image(src, width, height, alt) {
var img = document.createElement("img");
img.src = src;
img.width = width;
img.height = height;
img.alt = alt;
// This next line will just add it to the <body> tag
document.body.appendChild(img);
}
Then you could use it like this...
<button onclick=
"show_image('http://google.com/images/logo.gif',
276,
110,
'Google Logo');">Add Google Logo</button>
This worked for me:
p { margin-left: -2em;
text-indent: 2em
}
JavaScript has built in to it a function called setInterval
, which takes two arguments - a function, callback
and an integer, timeout
. When called, setInterval
will call the function you give it every timeout
milliseconds.
For example, if you wanted to make an alert window every 500 milliseconds, you could do something like this.
function makeAlert(){
alert("Popup window!");
};
setInterval(makeAlert, 500);
However, you don't have to name your function or declare it separately. Instead, you could define your function inline, like this.
setInterval(function(){ alert("Popup window!"); }, 500);
Once setInterval
is called, it will run until you call clearInterval
on the return value. This means that the previous example would just run infinitely. We can put all of this information together to make a progress bar that will update every second and after 10 seconds, stop updating.
var timeleft = 10;_x000D_
var downloadTimer = setInterval(function(){_x000D_
if(timeleft <= 0){_x000D_
clearInterval(downloadTimer);_x000D_
}_x000D_
document.getElementById("progressBar").value = 10 - timeleft;_x000D_
timeleft -= 1;_x000D_
}, 1000);
_x000D_
<progress value="0" max="10" id="progressBar"></progress>
_x000D_
Alternatively, this will create a text countdown.
var timeleft = 10;_x000D_
var downloadTimer = setInterval(function(){_x000D_
if(timeleft <= 0){_x000D_
clearInterval(downloadTimer);_x000D_
document.getElementById("countdown").innerHTML = "Finished";_x000D_
} else {_x000D_
document.getElementById("countdown").innerHTML = timeleft + " seconds remaining";_x000D_
}_x000D_
timeleft -= 1;_x000D_
}, 1000);
_x000D_
<div id="countdown"></div>
_x000D_
You have to learn Smarty syntax. That's a template system.
here are two samples: http://jsfiddle.net/H5q5h/1/
one uses float:left
and a wrapper with overflow:hidden
. the wrapper ensures the sibling of the wrapper starts below the wrapper.
the 2nd one uses the more recent display:inline-block
and wrapper can be disregarded. but this is not generally supported by older browsers so tread lightly on this one. also, any white space between the items will cause an unnecessary "margin-like" white space on the left and right of the item divs.
Check if you could go with any of the below mentioned JQuery plugins. Simply awesome and provide wide range of options to work through, and less pains to integrate. :)
https://github.com/paulopmx/Flexigrid - Flexgrid
http://datatables.net/index - Data tables.
https://github.com/tonytomov/jqGrid
If not, you need to have a link to those table headers that calls a server-side script to invoke the sort.
Most browsers will simply ignore any NON-hex values in your color string, substituting non-hex digits with zeros.
ChuCknorris
translates to c00c0000000
. At this point, the browser will divide the string into three equal sections, indicating Red, Green and Blue values: c00c 0000 0000
. Extra bits in each section will be ignored, which makes the final result #c00000
which is a reddish color.
Note, this does not apply to CSS color parsing, which follow the CSS standard.
<p><font color='chucknorris'>Redish</font></p>_x000D_
<p><font color='#c00000'>Same as above</font></p>_x000D_
<p><span style="color: chucknorris">Black</span></p>
_x000D_
I had a similar issue with the iteration and I landed here. Maybe someone else is also doing the same mistake I did.
In my case, the selector was not the problem at all. The problem was that I had messed up the javascript code:
I had a loop and a subloop. The subloop was also using i
as a counter, instead of j
, so because the subloop was overriding the value of i
of the main loop, this one never got to the second iteration.
var dayContainers = document.getElementsByClassName('day-container');
for(var i = 0; i < dayContainers.length; i++) { //loop of length = 2
var thisDayDiv = dayContainers[i];
// do whatever
var inputs = thisDayDiv.getElementsByTagName('input');
for(var j = 0; j < inputs.length; j++) { //loop of length = 4
var thisInput = inputs[j];
// do whatever
};
};
transition-property:width;
This should work. you have to have browser dependent code
I Found a way Accidentally Now: you can need use this: data-error:""
<input type="username" class="form-control" name="username" value=""
placeholder="the least 4 character"
data-minlength="4" data-minlength-error="the least 4 character"
data-error="This is a custom Errot Text fot patern and fill blank"
max-length="15" pattern="[A-Za-z0-9]{4,}"
title="4~15 character" required/>
"background-size: cover;" causes a lot of issues on all mobile browsers except Firefox!
This fixed my issue:
/* Mobile first */
body{
background-image: url(bg_mobile.jpg);
background-attachment: fixed;
background-repeat: no-repeat;
}
/* Then tablets, laptops and desktops (768px and up) */
@media screen and (min-width:768px) {
body{
background-image: url(bg.jpg);
background-size: cover;
}
}
For div refreshing without creating div inside yours with same id, you should use this inside your function
$("#yourDiv").load(" #yourDiv > *");
Checkout the Ruby CGI class. There are methods to encode and decode HTML as well as URLs.
CGI::escapeHTML('Usage: foo "bar" <baz>')
# => "Usage: foo "bar" <baz>"
Original from Sept. 13, 2015:
Quick and easy.
$.each(yourArray, function(index, value){
$('.element').html( $('.element').html() + '<span>' + value +'</span>')
});
Update Sept 9, 2019: No jQuery is needed to iterate the array.
yourArray.forEach((value) => {
$(".element").html(`${$(".element").html()}<span>${value}</span>`);
});
/* --- Or without jQuery at all --- */
yourArray.forEach((value) => {
document.querySelector(".element").innerHTML += `<span>${value}</span>`;
});
I don't think you can turn JavaScript objects into JSON strings using only jQuery, assuming you need the JSON string as output.
Depending on the browsers you are targeting, you can use the JSON.stringify
function to produce JSON strings.
See http://www.json.org/js.html for more information, there you can also find a JSON parser for older browsers that don't support the JSON object natively.
In your case:
var array = [];
$("input[class=email]").each(function() {
array.push({
title: $(this).attr("title"),
email: $(this).val()
});
});
// then to get the JSON string
var jsonString = JSON.stringify(array);
That's something I'm not sure that you can change through the HTML of the webpage itself, it's a client-side setting to tell their browser if they want security to be high. Most other browsers will not do this but from what I'm aware of this is not possible to stop unless the user disables the feature.
Does it still do what you want it to do after you click on 'Allow'? If so then it shouldn't be too much of a problem
$("#YOUR-BUTTON").on('click', function(e) {
e.preventDefault();
$('html, body').animate({
scrollTop: $("#YOUR-TARGET").offset().top
}, 300);
});
Delete all spaces and line breaks between <textarea>
opening and closing </textarea>
tags.
<textarea placeholder="YOUR TEXT"></textarea> ///Correct one
<textarea placeholder="YOUR TEXT"> </textarea> ///Bad one It's treats as a value so browser won't display the Placeholder value
<textarea placeholder="YOUR TEXT">
</textarea> ///Bad one
Html Code :
<a id="f">Show First content!</a>
<br/>
<a id="s">Show Second content!!</a>
<div class="a">Default Content</div>
<div class="ab hideDiv">First content</div>
<div class="abc hideDiv">Second content</div>
Script code:
$(document).ready(function() {
$("#f").mouseover(function(){
$('.a,.abc').addClass('hideDiv');
$('.ab').removeClass('hideDiv');
}).mouseout(function() {
$('.a').removeClass('hideDiv');
$('.ab,.abc').addClass('hideDiv');
});
$("#s").mouseover(function(){
$('.a,.ab').addClass('hideDiv');
$('.abc').removeClass('hideDiv');
}).mouseout(function() {
$('.a').removeClass('hideDiv');
$('.ab,.abc').addClass('hideDiv');
});
});
css code:
.hideDiv
{
display:none;
}
Its works for me.
<style type="text/css">
td {
/* css-3 */
white-space: -o-pre-wrap;
word-wrap: break-word;
white-space: pre-wrap;
white-space: -moz-pre-wrap;
white-space: -pre-wrap;
}
And table attribute is:
table {
table-layout: fixed;
width: 100%
}
You have set #slider
as absolute
, which means that it "is positioned relative to the nearest positioned ancestor" (confusing, right?). Meanwhile, #content
div is placed relative, which means "relative to its normal position". So the position of the 2 divs is not related.
You can read about CSS positioning here
If you set both to relative
, the divs will be one after the other, as shown here:
#slider {
position:relative;
left:0;
height:400px;
border-style:solid;
border-width:5px;
}
#slider img {
width:100%;
}
#content {
position:relative;
}
#content #text {
position:relative;
width:950px;
height:215px;
color:red;
}
Here is a solution that builds upon the accepted answer. It corrects for: column widths, matching table style, and when the table is scrolled in a container div.
Usage
Ensure your table has a <thead>
tag because only thead content will be fixed.
$("#header-fixed").fixHeader();
JavaSript
//Custom JQuery Plugin
(function ($) {
$.fn.fixHeader = function () {
return this.each(function () {
var $table = $(this);
var $sp = $table.scrollParent();
var tableOffset = $table.position().top;
var $tableFixed = $("<table />")
.prop('class', $table.prop('class'))
.css({ position: "fixed", "table-layout": "fixed", display: "none", "margin-top": "0px" });
$table.before($tableFixed);
$tableFixed.append($table.find("thead").clone());
$sp.bind("scroll", function () {
var offset = $(this).scrollTop();
if (offset > tableOffset && $tableFixed.is(":hidden")) {
$tableFixed.show();
var p = $table.position();
var offset = $sp.offset();
//Set the left and width to match the source table and the top to match the scroll parent
$tableFixed.css({ left: p.left + "px", top: (offset ? offset.top : 0) + "px", }).width($table.width());
//Set the width of each column to match the source table
$.each($table.find('th, td'), function (i, th) {
$($tableFixed.find('th, td')[i]).width($(th).width());
});
}
else if (offset <= tableOffset && !$tableFixed.is(":hidden")) {
$tableFixed.hide();
}
});
});
};
})(jQuery);
Small And Better One
var i = 0;
$("#container > option").each(function(){
if($(this).val().length > i) {
i = $(this).val().length;
console.log(i);
console.log($(this).val());
}
});
When using the <button>
element (or maybe others?) setting 'value' will not change the text, but innerHTML
will.
var btn = document.getElementById("mybtn");
btn.value = 'my value'; // will just add a hidden value
btn.innerHTML = 'my text';
When printed to the console:
<button id="mybtn" class="btn btn-primary" onclick="confirm()" value="my value">my text</button>
I have been using:
<a href=".">link</a>
Have yet to find a case and/or browser where it does not work as intended.
Period means the current path. You can also use ..
to refer to the folder above the current path, for instance, if you have this file structure:
page1.html
folder1
page2.html
You can then in page2.html
write:
<a href="../page1.html">link to page 1</a>
EDIT:
I'm not sure if the behaviour has changed or if it was always like this, but Chrome (and maybe others) will treat periods as described above as regarding directories, not files. This means that if you are at http://example.com/foo/bar.html
you are really in the directory /foo/
and a href
value of .
in bar.html
will refer to /foo/
rather than bar.html
Think of it as navigating the file system in a terminal; you can never cd
into a file :)
EDIT 2:
It seems like the behaviour of using href="."
is not as predictable anymore, both Firefox and Chrome might have changed how they handle these. I wouldn't rely entirely on my original answer, but rather try both the empty string and the period in different browsers for your specific use and make sure you get the desired behaviour.
Now, there are plenty of example of me answering questions with essays on why following validation rules are important. I've also said that sometimes you just have to be a rebel and break the rules, and document the reasons.
You can see in this example that framesets do work in HTML5 still. I had to download the code and add an HTML5 doctype at the top, however. But the frameset element was still recognized, and the desired result was achieved.
Therefore, knowing that using framesets is completely absurd, and knowing that you have to use this as dictated by your professor/teacher, you could just deal with the single validation error in the W3C validator and use both the HTML5 video element as well as the deprecated frameset element.
<!DOCTYPE html>
<html>
<head>
</head>
<!-- frameset is deprecated in html5, but it still works. -->
<frameset framespacing="0" rows="150,*" frameborder="0" noresize>
<frame name="top" src="http://www.npscripts.com/framer/demo-top.html" target="top">
<frame name="main" src="http://www.google.com" target="main">
</frameset>
</html>
Keep in mind that if it's a project for school, it's most likely not going to be something that will be around in a year or two once the browser vendors remove frameset support for HTML5 completely. Just know that you are right and just do what your teacher/professor asks just to get the grade :)
UPDATE:
The toplevel parent doc uses XHTML and the frame uses HTML5. The validator did not complain about the frameset being illegal, and it didn't complain about the video element.
index.php:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">

<frameset framespacing="0" rows="150,*" frameborder="0" noresize>
<frame name="top" src="http://www.npscripts.com/framer/demo-top.html" target="top">

</frameset>
</html>
video.html:
<!doctype html>

If you're using Twig template engine, you can use spaceless:
<p>
{% spaceless %}
<span>Foo</span>
<span>Bar</span>
{% endspaceless %}
</p>
Note whilst this doesn't address the exact question asked, this could be useful if someone has Twig at their disposal, to avoid using some lesser solution.
Simple solution for vertical align middle... for me it works like a charm
ul{display:table; text-align:center; margin:0 auto;}
li{display:inline-block; text-align:center;}
li.items_inside_li{display:inline-block; vertical-align:middle;}
This is exactly what you want
$(document).tooltip({ selector: "[title]",_x000D_
placement: "top",_x000D_
trigger: "focus",_x000D_
animation: false});
_x000D_
<form id="form">_x000D_
<label for="myinput1">Browser tooltip appears on hover but disappears on clicking the input field. But this one persists while user is typing within the field</label>_x000D_
<input id="myinput1" type="text" title="This tooltip persists" />_x000D_
<input id="myinput2" type="text" title="This one also" />_x000D_
</form>

If you have the authority to edit the pages to be opened, you can href to 'A' page and in the A page you can put link to B page in onpageload attribute of body tag.
Add bottom:100%
to your #menu:hover ul li:hover ul
rule
#menu:hover ul li:hover ul {
position: absolute;
margin-top: 1px;
font: 10px;
bottom: 100%; /* added this attribute */
}
Or better yet to prevent the submenus from having the same effect, just add this rule
#menu>ul>li:hover>ul {
bottom:100%;
}
source: http://jsfiddle.net/W5FWW/4/
And to get back the border you can add the following attribute
#menu>ul>li:hover>ul {
bottom:100%;
border-bottom: 1px solid transparent
}
Using Blob:
var iframe = document.getElementById("myiframe");
var blob = new Blob([s], {type: "text/html; charset=utf-8"});
iframe.src = URL.createObjectURL(blob);
You can use this class : class="sticky-top alert alert-dismissible"
Until I get a better option, this is the most "bootstrappy" answer I can work out:
JSFiddle: http://jsfiddle.net/TrueBlueAussie/6cbrjrt5/
I have switched to using LESS and including the Bootstrap Source NuGet package to ensure compatibility (by giving me access to the bootstrap variables.less
file:

right: 0;
left: 0;
overflow-y: auto;
}
}
}
The remaining problem is there seems to be no defining variable for the footer height
in bootstrap. If someone call tell me if there is a magic 30px variable defined in Bootstrap I would appreciate it.
window.addEventListener("scroll", function(evt) {
var pos_top = document.body.scrollTop;
if(pos_top == 0){
$('#divID').css('position','fixed');
}
else if(pos_top > 0){
$('#divId').css('position','static');
}
});
to set height of table to its container I must do:
1) set "position: absolute"
2) remove redundant contents of cells (!)
if anyone else has problem with the above mentioned solutions, I ended up just going for the event:
$("#jquery_audioPlayer").jPlayer({
ready:function () {
$(this).jPlayer("setMedia", {
mp3:"media/song.mp3"
})
...
pause: function () {
$('#yoursoundcontrol').click(function () {
$("#jquery_audioPlayer").jPlayer('play');
})
},
play: function () {
$('#yoursoundcontrol').click(function () {
$("#jquery_audioPlayer").jPlayer('pause');
})}
});
works for me.
If you are using jQuery,
$(function() {...});
is equivalent to
$(document).ready(function () { })
or another short hand:
$().ready(function () { })
See What event does JQuery $function() fire on? and https://api.jquery.com/ready/
You should read up on the onclick
html attribute and the window.open()
documentation. Below is what you want.
<a href='#' onclick='window.open("http://www.google.com", "myWin", "scrollbars=yes,width=400,height=650"); return false;'>1</a>
_x000D_
JSFiddle: http://jsfiddle.net/TBcVN/
Try creating a class named overlay
and apply the following css to it:
a.overlay { width: 100%; height:100%; position: absolute; }
Make sure it is placed in a positioned element.
Now simply place an <a>
tag with that class inside the div you want to be linkable:
<div id="buttonOne">
<a class="overlay" href="......."></a>
<div id="linkedinB">
<img src="img/linkedinB.png" alt="never forget the alt tag" width="40" height="40"/>
</div>
</div>
PhilipK's suggestion might work but it won't validate because you can't place a block element (div
) inside an inline element (a
). And when your website doesn't validate the W3C Ninja's will come for you!
An other advice would be to try avoiding inline styling.
Since callto:
is per default supported by skype (set up in Skype settings), and others do also support it, I would recommend using callto:
rather than skype:
.
That is the right code. What is probably happening is your form is submitting, and you see the new page (where the element will exist again).
Try to replace the
padding: 2px 30px 2px 2px;
with
padding: 2px 2px 2px 2px;
It should work.
"<pre>"
is an HTML tag. If you insert this line of code in your program
echo "<pre>";
then you will enable the viewing of multiple spaces and line endings. Without this, all \n
, \r
and other end line characters wouldn't have any effect in the browser and wherever you had more than 1 space in the code, the output would be shortened to only 1 space. That's the default HTML. In that case only with <br>
you would be able to break the line and go to the next one.
For example,
the code below would be displayed on multiple lines, due to \n
line ending specifier.
<?php
echo "<pre>";
printf("<span style='color:#%X%X%X'>Hello</span>\n", 65, 127, 245);
printf("Goodbye");
?>
However the following code, would be displayed in one line only (line endings are disregarded).
<?php
printf("<span style='color:#%X%X%X'>Hello</span>\n", 65, 127, 245);
printf("Goodbye");
?>
You would simply use jQuery like so...
<script>
jQuery(function(){
jQuery('#modal').click();
});
</script>
Use the click function to auto-click the #modal button
You can give the tr an id and do it.
tr#element{
background-color: green;
cursor: pointer;
height: 30px;
}
tr#element:hover{
background-color: blue;
cursor: pointer;
}
<table width="400px">
<tr id="element">
<td></td>
</tr>
</table>
I had this problem today, was in a lot of time crunch, so below idea worked:
Fade is not there, but that bootstrap feeling will be there.
Hope that helps.
<pre><form name="myform" action="saveNew" method="post" enctype="multipart/form-data">
<input type="text" id="name" name="name" />
<input type="submit"/>
</form></pre>
<script language="JavaScript" type="text/javascript">
var frmvalidator = new Validator("myform");
frmvalidator.EnableFocusOnError(false);
frmvalidator.EnableMsgsTogether();
frmvalidator.addValidation("name","req","Plese Enter Name");
</script>
before using above code you have to add the gen_validatorv31.js js file
You can make a .png image and then use one of the following snippets between the <head>
tags of your static HTML documents:
<link rel="icon" type="image/png" href="/favicon.png"/>
<link rel="icon" type="image/png" href="https://example.com/favicon.png"/>
A working example using the method mentioned above and using JSON to represent the data. This is used in my project of dealing with ajax calls fetching data from server.
http://jsfiddle.net/vinocui/22mX6/1/
In your html: < table id='here_table' >< /table >
JS code:
function feed_table(tableobj){
// data is a JSON object with
//{'id': 'table id',
// 'header':[{'a': 'Asset Tpe', 'b' : 'Description', 'c' : 'Assets Value', 'd':'Action'}],
// 'data': [{'a': 'Non Real Estate', 'b' :'Credit card', 'c' :'$5000' , 'd': 'Edit/Delete' },... ]}
$('#' + tableobj.id).html( '' );
$.each([tableobj.header, tableobj.data], function(_index, _obj){
$.each(_obj, function(index, row){
var line = "";
$.each(row, function(key, value){
if(0 === _index){
line += '<th>' + value + '</th>';
}else{
line += '<td>' + value + '</td>';
}
});
line = '<tr>' + line + '</tr>';
$('#' + tableobj.id).append(line);
});
});
}
// testing
$(function(){
var t = {
'id': 'here_table',
'header':[{'a': 'Asset Tpe', 'b' : 'Description', 'c' : 'Assets Value', 'd':'Action'}],
'data': [{'a': 'Non Real Estate', 'b' :'Credit card', 'c' :'$5000' , 'd': 'Edit/Delete' },
{'a': 'Real Estate', 'b' :'Property', 'c' :'$500000' , 'd': 'Edit/Delete' }
]};
feed_table(t);
});
This is what worked for me in Chrome and Firefox! This will open the little print window and close it automatically once you've clicked print.
var printContents = document.getElementById('div-id-selector').innerHTML;
var popupWin = window.open('', '_blank', 'width=800,height=800,scrollbars=no,menubar=no,toolbar=no,location=no,status=no,titlebar=no,top=50');
popupWin.window.focus();
popupWin.document.open();
popupWin.document.write('<!DOCTYPE html><html><head><title>TITLE OF THE PRINT OUT</title>'
+'<link rel="stylesheet" type="text/css" href="app/directory/file.css" />'
+'</head><body onload="window.print(); window.close();"><div>'
+ printContents + '</div></html>');
popupWin.document.close();
You could do it on the client with moment-timezone and send the value to server; sample usage:
> moment.tz.guess()
"America/Asuncion"
This questions is already answered here. Just put height: 100%
in both the div
and the container td
.
CKEDITOR.config.enterMode = CKEDITOR.ENTER_BR;
- this works perfectly for me.
Have you tried clearing your browser cache - this is an issue sometimes.
You can also check it out with the jQuery adapter:
<script type="text/javascript" src="/js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="/js/ckeditor/adapters/jquery.js"></script>
<script type="text/javascript">
$(function() {
$('#your_textarea').ckeditor({
toolbar: 'Full',
enterMode : CKEDITOR.ENTER_BR,
shiftEnterMode: CKEDITOR.ENTER_P
});
});
</script>
UPDATE according to @Tomkay's comment:
Since version 3.6 of CKEditor you can configure if you want inline content to be automatically wrapped with tags like <p></p>
. This is the correct setting:
CKEDITOR.config.autoParagraph = false;
Source: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph
<td rowspan="2" style="text-align:left;vertical-align:top;padding:0">Save a lot</td>
That should do it.
You can try following sample http://jsfiddle.net/xKJB8/3/
<img id="preview" src="http://www.gravatar.com/avatar/0e39d18b89822d1d9871e0d1bc839d06?s=128&d=identicon&r=PG">
<canvas id="myCanvas" />
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var img = document.getElementById("preview");
ctx.drawImage(img, 10, 10);
alert(c.toDataURL());
There are multiple suggestions here, but as far as I can see the jQuery UI guys have broken the dialogue control at present.
I say this because I include a dialogue on my page, and its semi transparent and the modal blanking div is behind some other elements. That can't be right!
In the end based on some other posts I developed this global solution, as an extension to the dialogue widget. It works for me but I'm not sure what it would do if I opened a dialogue from within a dialogue.
Basically it looks for the zIndex of everything else on the page and moves the .ui-widget-overlay to be one higher, and the dialogue itself to be one higher than that.
$.widget("ui.dialog", $.ui.dialog,
{
open: function ()
{
var $dialog = $(this.element[0]);
var maxZ = 0;
$('*').each(function ()
{
var thisZ = $(this).css('zIndex');
thisZ = (thisZ === 'auto' ? (Number(maxZ) + 1) : thisZ);
if (thisZ > maxZ) maxZ = thisZ;
});
$(".ui-widget-overlay").css("zIndex", (maxZ + 1));
$dialog.parent().css("zIndex", (maxZ + 2));
return this._super();
}
});
Thanks to the following, as this is where I got the info from of how to do this: https://stackoverflow.com/a/20942857
http://learn.jquery.com/jquery-ui/widget-factory/extending-widgets/
You can simply add a right float to .block2 element and place it in the first position (this is very important).
Here is the code:
<html>
<head>
<style type="text/css">
.block1 {
color: red;
width: 100px;
border: 1px solid green;
}
.block2 {
color: blue;
width: 70px;
border: 2px solid black;
position: relative;
float: right;
}
</style>
</head>
<body>
<div class='block1'>
<div class='block2'>block2</div>
<p>text</p>
<p>text2</p>
</div>
</body>
Regards...
You can do this:
$(function() {
$("#mainTable").width(100).height(200);
});
This has 2 changes, it now uses .width()
and .height()
, as well as runs the code on the document.ready
event.
Without the $(function() { })
wrapper (or $(document).ready(function() { })
if you prefer), your element may not be present yet, so $("#mainTable")
just wouldn't find anything to...well, do stuff to. You can see a working example here.
.textbox {
height: 40px;
}
<div id=signin>
<input type="text" class="textbox" size="25%" height="50"/></br>
<input type="text" class="textbox" size="25%" height="50"/>
Make the font size larger and add height (or line height to the input boxes) I would not recommend adding those size and height attributes in the HTML as that can be handled by CSS. I have made a class text-box that can be used for multiple input boxes
There is an important bit that is not mentioned in the article to which you linked and that is flex-basis
. By default flex-basis
is auto
.
From the spec:
If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)
Each flex item has a flex-basis
which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow
) among the items. With auto
, that basis is the contents size (or defined size with width
, etc.). As a result, items with bigger text within are being given more space overall in your example.
If you want your elements to be completely even, you can set flex-basis: 0
. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow
.
li {
flex-grow: 1;
flex-basis: 0;
/* ... */
}
This diagram from the spec does a pretty good job of illustrating the point.
And here is a working example with your fiddle.
Generally on Android, if you simply display the phone number, and the user taps on it, it will pull it up in the dialer. So, you could simply do
For more information, call us at <b>416-555-1234</b>
When the user taps on the bold part, since it's formatted like a phone number, the dialer will pop up, and show 4165551234
in the phone number field. The user then just has to hit the call button.
You might be able to do
For more information, call us at <a href='tel:416-555-1234'>416-555-1234</a>
to cover both devices, but I'm not sure how well this would work. I'll give it a try shortly and let you know.
EDIT: I just gave this a try on my HTC Magic running a rooted Rogers 1.5 with SenseUI:
For more information, call us at <a href='tel:416-555-1234'>416-555-1234</a><br />
<br />
Call at <a href='tel:416-555-1234'>our number</a>
<br />
<br />
<a href='416-555-1234'>Blah</a>
<br />

The first one, surrounding with the link and printing the phone number, worked perfectly. Pulled up the dialer with the hyphens and all. The second, saying our number
with the link, worked exactly the same. This means that using <a href='tel:xxx-xxx-xxxx'>
should work across the board, but I wouldn't suggest taking my one test as conclusive.
Linking straight to the number did the expected: Tried to pull up the nonexistent file from the server.
The last one did as I mentioned above, and pulled up the dialer, but without the nice formatting hyphens.
Try this :
<style type="text/css">
.myTableStyle
{
position:absolute;
top:50%;
left:50%;
/*Alternatively you could use: */
/*
position: fixed;
bottom: 50%;
right: 50%;
*/
}
</style>
If every element in b has different lengths, then you need to do something like:
int totalLength = 0;
for_every_element_in_b {
totalLength += length_of_this_b_in_bytes;
}
return (char **)malloc(totalLength);
Go to Help->Install Software. Add the following link http://dl-ssl.google.com/android/eclipse/ .
Then press next and accept the license, it installs some of the software required then you will be gud to go.
After the eclipse restarts it prompts you to download the android sdk required or give the path of android sdk if already it is downloaded.
This works all the time what ever may be the version.
When the above solution doesn’t work try this:
<IfModule mod_security.c>
SecRuleEngine Off
SecFilterInheritance Off
SecFilterEngine Off
SecFilterScanPOST Off
SecRuleRemoveById 300015 3000016 3000017
</IfModule>
#!/bin/sh
WID=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)"| awk '{print $5}')
xdotool windowfocus $WID
xdotool key ctrl+shift+t
wmctrl -i -a $WID
This will auto determine the corresponding terminal and opens the tab accordingly.
Try this code:
private void RegisterInStartup(bool isChecked)
{
RegistryKey registryKey = Registry.CurrentUser.OpenSubKey
("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
if (isChecked)
{
registryKey.SetValue("ApplicationName", Application.ExecutablePath);
}
else
{
registryKey.DeleteValue("ApplicationName");
}
}

For what purpose is this function useful?
One particular usage is counting with a dictionary. Let's assume you want to count the number of occurrences of each element in a given list. The common way to do so is to make a dictionary where keys are elements and values are the number of occurrences.
fruits = ['apple', 'banana', 'peach', 'apple', 'pear']
d = {}
for fruit in fruits:
if fruit not in d:
d[fruit] = 0
d[fruit] += 1
Using the .get()
method, you can make this code more compact and clear:
for fruit in fruits:
d[fruit] = d.get(fruit, 0) + 1
DELETE FROM ... WHERE id=...;
protected function templateRemove($id){
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('XXXBundle:Templates')->findOneBy(array('id' => $id));
if ($entity != null){
$em->remove($entity);
$em->flush();
}
}
You can try the following:
gitk --all
You can tell gitk
what to display using anything that git rev-list
understands, so if you just want a few branches, you can do:
gitk master origin/master origin/experiment
... or more exotic things like:
gitk --simplify-by-decoration --all
In my case the symbols I create (Tax1, Tax2, etc.) already had values but I wanted to use a loop and assign the symbols to another variable. So the above two answers gave me a way to accomplish this. This may be helpful in answering your question as the assignment of a value can take place anytime later.
output=NULL
for(i in 1:8){
Tax=eval(as.symbol(paste("Tax",i,sep="")))
L_Data1=L_Data_all[which(L_Data_all$Taxon==Tax[1] | L_Data_all$Taxon==Tax[2] | L_Data_all$Taxon==Tax[3] | L_Data_all$Taxon==Tax[4] | L_Data_all$Taxon==Tax[5]),]
L_Data=L_Data1$Length[which(L_Data1$Station==Plant[1] | L_Data1$Station==Plant[2])]
h=hist(L_Data,breaks=breaks,plot=FALSE)
output=cbind(output,h$counts)
}
A solution is to create your own jquery plugin that take the json map and populate the select with it.
(function($) {
$.fn.fillValues = function(options) {
var settings = $.extend({
datas : null,
complete : null,
}, options);
this.each( function(){
var datas = settings.datas;
if(datas !=null) {
$(this).empty();
for(var key in datas){
$(this).append('<option value="'+key+'"+>'+datas[key]+'</option>');
}
}
if($.isFunction(settings.complete)){
settings.complete.call(this);
}
});
}
}(jQuery));
You can call it by doing this :
$("#select").fillValues({datas:your_map,});
The advantages is that anywhere you will face the same problem you just call
$("....").fillValues({datas:your_map,});
Et voila !
You can add functions in your plugin as you like
You can use a subselect in your from query (untested and not sure which is faster):
SELECT Grade, COUNT(*) / TotalRows
FROM (SELECT Grade, COUNT(*) As TotalRows
FROM myTable) Grades
GROUP BY Grade, TotalRows
Or
SELECT Grade, SUM(PartialCount)
FROM (SELECT Grade, 1/COUNT(*) AS PartialCount
FROM myTable) Grades
GROUP BY Grade
Or
SELECT Grade, GradeCount / SUM(GradeCount)
FROM (SELECT Grade, COUNT(*) As GradeCount
FROM myTable
GROUP BY Grade) Grades
You can also use a stored procedure (apologies for the Firebird syntax):
SELECT COUNT(*)
FROM myTable
INTO :TotalCount;
FOR SELECT Grade, COUNT(*)
FROM myTable
GROUP BY Grade
INTO :Grade, :GradeCount
DO
BEGIN
Percent = :GradeCount / :TotalCount;
SUSPEND;
END
CN refers to class name, so put in your LDAP query CN=Users. Should work.
It's actually easier than everyone's making it sound... especially if you use the $.ajax({})
base syntax vs. one of the helper functions.
Just pass in the key: value
pair like you would on any object, when you setup your ajax request... (because $(this)
hasn't changed context yet, it's still the trigger for the bind call above)
<script type="text/javascript">
$(".qty input").bind("keypress change", function() {
$.ajax({
url: "/order_items/change/"+$(this).attr("data-order-item-id")+"/qty:"+$(this).val()+"/returnas.json",
type: "POST",
dataType: "json",
qty_input: $(this),
anything_else_i_want_to_pass_in: "foo",
success: function(json_data, textStatus, jqXHR) {
/* here is the input, which triggered this AJAX request */
console.log(this.qty_input);
/* here is any other parameter you set when initializing the ajax method */
console.log(this.anything_else_i_want_to_pass_in);
}
});
});
</script>
One of the reasons this is better than setting the var, is that the var is global and as such, overwritable... if you have 2 things which can trigger ajax calls, you could in theory trigger them faster than ajax call responds, and you'd have the value for the second call passed into the first. Using this method, above, that wouldn't happen (and it's pretty simple to use too).
If you want to search for the last instance of a string in a text, you can run rfind.
Example:
s="Hello"
print s.rfind('l')
output: 3
*no import needed
Complete syntax:
stringEx.rfind(substr, beg=0, end=len(stringEx))
Another solution not mentioned yet is to use: rewind(stdin);
You can use print -p -- in the script to do this example :
#!/bin/ksh
mysql -u username -ppassword -D dbname -ss -n -q |&
print -p -- "select count(*) from some_table;"
read -p get_row_count1
print -p -- "select count(*) from some_other_table;"
read -p get_row_count2
print -p exit ;
#
echo $get_row_count1
echo $get_row_count2
#
exit
For those experiencing this error on CI/CD, adding the line below worked for me on my GitHub Actions CI/CD workflow right after running pip install pyflakes diff-cover
:
git fetch origin master:refs/remotes/origin/master
This is a snippet of the solution from the diff-cover github repo:
Solution: diff-cover matches source files in the coverage XML report with source files in the git diff. For this reason, it's important that the relative paths to the files match. If you are using coverage.py to generate the coverage XML report, then make sure you run diff-cover from the same working directory.
I got the solution on the links below. It is a documented diff-cover
error.
https://diff-cover.readthedocs.io/en/latest//README.html https://github.com/Bachmann1234/diff_cover/blob/master/README.rst
Hope this helps :-).
Microsoft Identity has extension methods which call async methods synchronously. For example there is GenerateUserIdentityAsync() method and equal CreateIdentity()
If you look at UserManagerExtensions.CreateIdentity() it look like this:
public static ClaimsIdentity CreateIdentity<TUser, TKey>(this UserManager<TUser, TKey> manager, TUser user,
string authenticationType)
where TKey : IEquatable<TKey>
where TUser : class, IUser<TKey>
{
if (manager == null)
{
throw new ArgumentNullException("manager");
}
return AsyncHelper.RunSync(() => manager.CreateIdentityAsync(user, authenticationType));
}
Now lets see what AsyncHelper.RunSync does
public static TResult RunSync<TResult>(Func<Task<TResult>> func)
{
var cultureUi = CultureInfo.CurrentUICulture;
var culture = CultureInfo.CurrentCulture;
return _myTaskFactory.StartNew(() =>
{
Thread.CurrentThread.CurrentCulture = culture;
Thread.CurrentThread.CurrentUICulture = cultureUi;
return func();
}).Unwrap().GetAwaiter().GetResult();
}
So, this is your wrapper for async method. And please don't read data from Result - it will potentially block your code in ASP.
There is another way - which is suspicious for me, but you can consider it too
Result r = null;
YourAsyncMethod()
.ContinueWith(t =>
{
r = t.Result;
})
.Wait();
Try the sql server management studio (version 2008 or earlier) from Microsoft. Download it from here. Not sure about the license, but it seems to be free if you download the EXPRESS EDITION.
You might also be able to use later editions of SSMS. For 2016, you will need to install an extension.
If you have the option you can copy the sdf file to a different machine which you are allowed to pollute with additional software.
Update: comment from Nick Westgate in nice formatting
The steps are not all that intuitive:
- Open SQL Server Management Studio, or if it's running select File -> Connect Object Explorer...
- In the Connect to Server dialog change Server type to SQL Server Compact Edition
- From the Database file dropdown select < Browse for more...>
- Open your SDF file.
Here's a little Tcl script that will do what you want. The Wish interpreter should be installed by default on Ubuntu.
#!/usr/bin/wish
pack [label .msg -text [lindex $argv 0]]
pack [entry .ent]
bind .ent <KeyPress-Return> { puts [.ent get]; destroy . }
focus .ent
Call it like this:

If you want to pursue a "simple" solution, you might find this class I put together useful:
http://www.architectshack.com/TextFileEncodingDetector.ashx
It does the BOM detection automatically first, and then tries to differentiate between Unicode encodings without BOM, vs some other default encoding (generally Windows-1252, incorrectly labelled as Encoding.ASCII in .Net).
As noted above, a "heavier" solution involving NCharDet or MLang may be more appropriate, and as I note on the overview page of this class, the best is to provide some form of interactivity with the user if at all possible, because there simply is no 100% detection rate possible!
Snippet in case the site is offline:

/*
* Simple class to handle text file encoding woes (in a primarily English-speaking tech
* world).
*
* - This code is fully managed, no shady calls to MLang (the unmanaged codepage
* detection library originally developed for Internet Explorer).
*
* - This class does NOT try to detect arbitrary codepages/charsets, it really only
* aims to differentiate between some of the most common variants of Unicode
* encoding, and a "default" (western / ascii-based) encoding alternative provided
* by the caller.
*
* - As there is no "Reliable" way to distinguish between UTF-8 (without BOM) and
* Windows-1252 (in .Net, also incorrectly called "ASCII") encodings, we use a
* heuristic - so the more of the file we can sample the better the guess. If you
* are going to read the whole file into memory at some point, then best to pass
* in the whole byte byte array directly. Otherwise, decide how to trade off
* reliability against performance / memory usage.
*
* - The UTF-8 detection heuristic only works for western text, as it relies on
* the presence of UTF-8 encoded accented and other characters found in the upper
* ranges of the Latin-1 and (particularly) Windows-1252 codepages.
*
* - For more general detection routines, see existing projects / resources:
* - MLang - Microsoft library originally for IE6, available in Windows XP and later APIs now (I think?)
* - MLang .Net bindings: http://www.codeproject.com/KB/recipes/DetectEncoding.aspx
* - CharDet - Mozilla browser's detection routines
* - Ported to Java then .Net: http://www.conceptdevelopment.net/Localization/NCharDet/
* - Ported straight to .Net: http://code.google.com/p/chardetsharp/source/browse

I know the answer is already given, but I think I've got another solution for this. You could take the array, reverse it and output the first array item like this:
var a = [1,2,3,4]; var lastItem = a.reverse()[0];
Works fine for me.
I had problems converting all columns to numeric with an apply()
call:
apply(data, 2, as.numeric)
The problem turns out to be because some of the strings had a comma in them -- e.g. "1,024.63" instead of "1024.63" -- and R does not like this way of formatting numbers. So I removed them and then ran as.numeric()
:
data = as.data.frame(apply(data, 2, function(x) {
y = str_replace_all(x, ",", "") #remove commas
return(as.numeric(y)) #then convert
}))
Note that this requires the stringr package to be loaded.
I'm thinking no. Bookmarks/favorites should be under the control of the user, imagine if any site you visited could insert itself into your bookmarks with just some javascript.
A session is a group of information on the server that is associated with the cookie information. If you're using PHP you can check the session. save _ path location and actually "see sessions". A cookie is a snippet of data sent to and returned from clients. Cookies are often used to facilitate sessions since it tells the server which client handled which session. There are other ways to do this (query string magic etc) but cookies are likely most common for this.
This code will do what you're looking for. It's based on examples found here and here.
The autofmt_xdate()
call is particularly useful for making the x-axis labels readable.

plt.bar(ind, OY, width=width)
plt.xticks(ind + width / 2, OX)
fig.autofmt_xdate()

Every answer uses .next()
or uses .beforeFirst()

API Sanity Checker — test framework for C/C++ libraries:
An automatic generator of basic unit tests for a shared C/C++ library. It is able to generate reasonable (in most, but unfortunately not all, cases) input data for parameters and compose simple ("sanity" or "shallow"-quality) test cases for every function in the API through the analysis of declarations in header files.
The quality of generated tests allows to check absence of critical errors in simple use cases. The tool is able to build and execute generated tests and detect crashes (segfaults), aborts, all kinds of emitted signals, non-zero program return code and program hanging.
Unique features in comparison with CppUnit, Boost and Google Test:

Even if you do xcode-select --install it was not fixing that for me as it showed some network error. The problem was that it could not connect to the app store. I did the following to fix it.

To write inline styling use:
<div style="height: 100px;">
asdfashdjkfhaskjdf
</div>
Inline styling serves a purpose however, it is not recommended in most situations.
The more "proper" solution, would be to make a separate CSS sheet, include it in your HTML document, and then use either an ID or a class to reference your div.
if you have the file structure:
index.html
>>/css/
>>/css/styles.css
Then in your HTML document between <head>
and </head>
write:
<link href="css/styles.css" rel="stylesheet" />
Then, change your div structure to be:
<div id="someidname" class="someclassname">
asdfashdjkfhaskjdf
</div>
In css, you can reference your div from the ID or the CLASS.
To do so write:
.someclassname { height: 100px; }
OR
#someidname { height: 100px; }
Note that if you do both, the one that comes further down the file structure will be the one that actually works.
For example... If you have:
.someclassname { height: 100px; }
.someclassname { height: 150px; }
Then in this situation the height will be 150px.
EDIT:
To answer your secondary question from your edit, probably need overflow: hidden;
or overflow: visible;
. You could also do this:
<div class="span12">
<div style="height:100px;">
asdfashdjkfhaskjdf
</div>
</div>
I often need to retrieve 'all' columns, except a few. so Select(x => x) does not work for me.
LINQPad's editor can auto-expand * to all columns.
after select '* all', LINQPad expands *, then I can remove not-needed columns.
If it suits anyone, here are some brief guidelines for adding environment variables permanently.
vi ~/.bash_profile
Add the variables to the file:
export DISPLAY=:0
export JAVA_HOME=~/opt/openjdk11
Immediately apply all changes:

In addition to Marty's excellent Answer, the SystemVerilog specification offers the byte
data type. The following declares a 4x8-bit variable (4 bytes), assigns each byte a value, then displays all values:
module tb;
byte b [4];
initial begin
foreach (b[i]) b[i] = 1 << i;
foreach (b[i]) $display("Address = %0d, Data = %b", i, b[i]);
$finish;
end
endmodule
This prints out:
Address = 0, Data = 00000001
Address = 1, Data = 00000010
Address = 2, Data = 00000100
Address = 3, Data = 00001000
This is similar in concept to Marty's reg [7:0] a [0:3];
. However, byte
is a 2-state data type (0 and 1), but reg
is 4-state (01xz). Using byte
also requires your tool chain (simulator, synthesizer, etc.) to support this SystemVerilog syntax. Note also the more compact foreach (b[i])
loop syntax.
The SystemVerilog specification supports a wide variety of multi-dimensional array types. The LRM can explain them better than I can; refer to IEEE Std 1800-2005, chapter 5.
I could see the style by following below steps suggested by Babiker - "Right-click element, but DON'T move your mouse pointer away from the element, keep it in hover state. Choose inspect element via keyboard, as in hit up arrow and then Enter key."
For changing style follow above steps and then - Change your browser tab by pressing ctrl + TAB on the keyboard. Then click back on the tab you want to debug. Your hover screen will still be there. Now carefully take your mouse to developer tool area.
The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.
If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.
Conceptually, the simplest regular expressions are literal characters. The pattern N
matches the character 'N'.
Regular expressions next to each other match sequences. For example, the pattern Nick
matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.
If you've ever used grep
on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re
in grep
refers to regular expressions.)
Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick
. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c]
matches either 'a' or 'b' or 'c'.
The pattern .
is special: rather than matching a literal dot only, it matches any character†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...]
.
Think of character classes as menus: pick just one.
Using .
can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]
. Digits are a frequent match target, so you could instead use the shortcut \d
. Others are \s
(whitespace) and \w
(word characters: alphanumerics or underscore).
The uppercased variants are their complements, so \S
matches any non-whitespace character, for example.
From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c
matches 'abc' or 'ac' because the ?
quantifier makes the subpattern it modifies optional. Other quantifiers are
*
(zero or more times)+
(one or more times){n}
(exactly n times){n,}
(at least n times){n,m}
(at least n times but no more than m times)Putting some of these blocks together, the pattern [Nn]*ick
matches all of
The first match demonstrates an important lesson: *
always succeeds! Any pattern can match zero times.
A few other useful examples:
[0-9]+
(and its equivalent \d+
) matches any non-negative integer\d{4}-\d{2}-\d{2}
matches dates formatted like 2019-01-01A quantifier modifies the pattern to its immediate left. You might expect 0abc+0
to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c
. This means 0abc+0
matches '0abc0', '0abcc0', '0abccc0', and so on.
To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0
. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr
.
Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick
. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |
, e.g., (Nick|nick)
.
For another example, you could equivalently write [a-c]
as a|b|c
, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.
Although some characters match themselves, others have special meanings. The pattern \d+
doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+
. A backslash removes the special meaning from the following character.
Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.
For example, say the input is
"Hello," she said, "How are you?"
You might expect ".+"
to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.
To switch from greedy to what you might think of as cautious, add an extra ?
to the quantifier. Now you understand how \((.+?)\)
, the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.
If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.
(As to your confusion, I don't know of any regular-expression dialect where ((.+?))
would do the same thing. I suspect something got lost in transmission somewhere along the way.)
Use the special pattern ^
to match only at the beginning of your input and $
to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.
Say you want to match comments of the form
-- This is a comment --
you'd write ^--\s+(.+)\s+--$
.
Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.
†: The statement above that .
matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n"
, but in practice you rarely expect a pattern such as .+
to cross a newline boundary. Perl regexes have a /s
switch and Java Pattern.DOTALL
, for example, to make .
match any character at all. For languages that don't have such a feature, you can use something like [\s\S]
to match "any whitespace or any non-whitespace", in other words anything.
Assuming your question was referring to an int, the following works for negative/positive and zero as well:
Math.Floor((decimal) Math.Abs(n)).ToString().Length
OpenId uses OAuth to deal with authentication.
By analogy, it's like .NET relies on Windows API. You could directly call Windows API but it's so wide, complex and method arguments so vast, you could easily make mistakes/bugs/security issue.
Same with OpenId/OAuth. OpenId relies on OAuth to manage Authentication but defining a specific Token (Id_token), digital signature and particular flows.

Running ALTER COLUMN
without mentioning attribute NOT NULL
will result in the column being changed to nullable, if it is already not. Therefore, you need to first check if the column is nullable and if not, specify attribute NOT NULL
. Alternatively, you can use the following statement which checks the nullability of column beforehand and runs the command with the right attribute.
IF COLUMNPROPERTY(OBJECT_ID('Employee', 'U'), 'Salary', 'AllowsNull')=0
ALTER TABLE [Employee]
ALTER COLUMN [Salary] NUMERIC(22,5) NOT NULL
ELSE
ALTER TABLE [Employee]
ALTER COLUMN [Salary] NUMERIC(22,5) NULL
Firefox is more stringent than other browsers and will require proper installation of an intermediate server certificate. This can be supplied by the cert authority the certificate was purchased from. the intermediate cert is typically installed in the same location as the server cert and requires the proper entry in the httpd.conf file.
while many are chastising Firefox for it's (generally) exclusive 'flagging' of this, it's actually demonstrating a higher level of security standards.
i couldn't change the permissions on the sharepoint i'm using but got a round it by uploading .url files with the drag and drop multiple files uploader.
Using the normal upload didn't work because they are intepreted by the file open dialog when you try to open them singly so it just tries to open the target not the .url file.
.url files can be made by saving a favourite with internet exploiter.
As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval
:
/*jshint evil:true */
function helloEval(str) {
/*jshint evil:true */
eval(str);
}

Loop counter iteration
The current idiom for looping over the indices makes use of the built-in range
function:
for i in range(len(sequence)):
# work with index i
Looping over both elements and indices can be achieved either by the old idiom or by using the new zip
built-in function:
for i in range(len(sequence)):
e = sequence[i]
# work with index i and element e
or
for i, e in zip(range(len(sequence)), sequence):
# work with index i and element e
Instead of
Player[PlayerCount] thePlayers;
you want
Player[] thePlayers = new Player[PlayerCount];
and
for(int i = 0; i < PlayerCount ; i++)
{
thePlayers[i] = new Player(i);
}
return thePlayers;
should return the array initialized with Player instances.

If the content has more than 1 line, adding a bottom border won't help. In that case you'll have to use,
text-decoration: underline;
text-decoration-style: dotted;
If you want more breathing space in between the text and the line, simply use,
text-underline-position: under;
The compiler doesn't get the intricate logic where you return in the last iteration of the loop, so it thinks that you could exit out of the loop and end up not returning anything at all.
Instead of returning in the last iteration, just return true after the loop:
public static bool isTwenty(int num) {
for(int j = 1; j <= 20; j++) {
if(num % j != 0) {
return false;
}
}
return true;
}
Side note, there is a logical error in the original code. You are checking if num == 20
in the last condition, but you should have checked if j == 20
. Also checking if num % j == 0
was superflous, as that is always true when you get there.
For me, it helped to link the projects current directory as such:
In the properties -> C++ -> General window, instead of linking the path to the file in "additional include directories". Put "." and uncheck "inheret from parent or project defaults".
Hope this helps.
The following code worked for me,
function timeDiffCalc(dateNow,dateFuture) {
var newYear1 = new Date(dateNow);
var newYear2 = new Date(dateFuture);
var dif = (newYear2 - newYear1);
var dif = Math.round((dif/1000)/60);
console.log(dif);
}

This procedure helped me solve the same problem.
In JavaScript you declare variables or functions by using the keywords var, let or function. In TypeScript classes you declare class members or methods without these keywords followed by a colon and the type or interface of that class member.
It’s just syntax sugar, there is no difference between:
var el: HTMLElement = document.getElementById('content');
and:
var el = document.getElementById('content');
On the other hand, because you specify the type you get all the information of your HTMLElement object.
This is not an issue, this is a design of Android. See here:
You should design each fragment as a modular and reusable activity component. That is, because each fragment defines its own layout and its own behavior with its own lifecycle callbacks, you can include one fragment in multiple activities, so you should design for reuse and avoid directly manipulating one fragment from another fragment.
A possible workaround would be to do something like this in your MainActivity:
Fragment someFragment;
...onCreate etc instantiating your fragments
public void myClickMethod(View v){
someFragment.myClickMethod(v);
}
and then in your Fragment class:
public void myClickMethod(View v){
switch(v.getid()){
// Your code here
}
}
using str.replace(regex, $1);
:
var str = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;

str = str.replace(regex, "$1" + "1" + "$2");
}

You can use django-ipware which supports Python 2 & 3 and handles IPv4 & IPv6.
Install:
pip install django-ipware
Simple Usage:
# In a view or a middleware where the `request` object is available
from ipware import get_client_ip
ip, is_routable = get_client_ip(request)
if ip is None:
# Unable to get the client's IP address
else:
# We got the client's IP address
if is_routable:
# The client's IP address is publicly routable on the Internet
else:
# The client's IP address is private
# Order of precedence is (Public, Private, Loopback, None)
Advanced Usage:
Custom Header - Custom request header for ipware to look at:
i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR'])
i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR', 'REMOTE_ADDR'])
Proxy Count - Django server is behind a fixed number of proxies:
i, r = get_client_ip(request, proxy_count=1)
Trusted Proxies - Django server is behind one or more known & trusted proxies:
i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2'))
# For multiple proxies, simply add them to the list
i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2', '177.3.3.3'))
# For proxies with fixed sub-domain and dynamic IP addresses, use partial pattern
i, r = get_client_ip(request, proxy_trusted_ips=('177.2.', '177.3.'))
Note: read this notice.
If you have a 200,000,000 character files and split that every five characters, you have 40,000,000 String
objects. Assume they are sharing actual character data with the original 400 MB String
(char
is 2 bytes). A String
is say 32 bytes, so that is 1,280,000,000 bytes of String
objects.
(It's probably worth noting that this is very implementation dependent. split
could create entirely strings with entirely new backing char[]
or, OTOH, share some common String
values. Some Java implementations to not use the slicing of char[]
. Some may use a UTF-8-like compact form and give very poor random access times.)
Even assuming longer strings, that's a lot of objects. With that much data, you probably want to work with most of it in compact form like the original (only with indexes). Only convert to objects that which you need. The implementation should be database like (although they traditionally don't handle variable length strings efficiently).
This works, at least in Android API 15
ImageView = imgv;
Resources res = getResources(); // need this to fetch the drawable
Drawable draw = res.getDrawable( R.drawable.image_name_in_drawable );

You could use setImageResource(), but the documentation specifies that "does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup ... consider using setImageDrawable() or setImageBitmap()." as stated by chetto
I recently encountered this problem and stumbled upon this question.
I resolved it with a much easier way.
Method One
You can either remove the dataType: 'json'
property from the object literal...
Method Two
Or you can do what @Sagiv was saying by returning your data as Json
.
The reason why this parsererror
message occurs is that when you simply return a string or another value, it is not really Json
, so the parser fails when parsing it.
So if you remove the dataType: json
property, it will not try to parse it as Json
.
With the other method if you make sure to return your data as Json
, the parser will know how to handle it properly.
The same as an int:
float f = 6;
Also here's how to programmatically convert from an int to a float, and a single in C# is the same as a float:
int i = 8;
float f = Convert.ToSingle(i);
Or you can just cast an int to a float:
float f = (float)i;
Simply Add 'carousel-item' class in place of item class.
You might be able to use the following for decoding, compressing and saving an image:
@Override
public void onClick(View view) {
onItemSelected1();
InputStream image_stream = null;
try {
image_stream = getContentResolver().openInputStream(myUri);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap image= BitmapFactory.decodeStream(image_stream );
// path to sd card
File path=Environment.getExternalStorageDirectory();
//create a file
File dir=new File(path+"/ComDec/");
dir.mkdirs();
Date date=new Date();
File file=new File(dir,date+".jpg");
OutputStream out=null;
try{
out=new FileOutputStream(file);
image.compress(format,size,out);
out.flush();
out.close();
MediaStore.Images.Media.insertImage(getContentResolver(), image," yourTitle "," yourDescription");
image=null;
}
catch (IOException e)
{
e.printStackTrace();
}
Toast.makeText(SecondActivity.this,"Image Save Successfully",Toast.LENGTH_LONG).show();
}
});
This is called the adjacent sibling selector, and it is represented by a plus sign...
h1.hc-reform + p {
clear:both;
}
Note: this is not supported in IE6 or older.
I tested as below. Hope it helps.
Integer[] integers1 = new Integer[10];
System.out.println(integers1.length); //it has length 10 but it is empty. It is not null array
for (Integer integer : integers1) {
System.out.println(integer); //prints all 0s
}
//But if I manually add 0 to any index, now even though array has all 0s elements
//still it is not empty
// integers1[2] = 0;
for (Integer integer : integers1) {
System.out.println(integer); //Still it prints all 0s but it is not empty
//but that manually added 0 is different
}
//Even we manually add 0, still we need to treat it as null. This is semantic logic.
Integer[] integers2 = new Integer[20];
integers2 = null; //array is nullified
// integers2[3] = null; //If I had int[] -- because it is priitive -- then I can't write this line.
if (integers2 == null) {
System.out.println("null Array");
}
The ngAfterContentChecked
lifecycle hook is triggered when bindings updates for the child components/directives have been already been finished. But you're updating the property that is used as a binding input for the ngClass
directive. That is the problem. When Angular runs validation stage it detects that there's a pending update to the properties and throws the error.
To understand the error better, read these two articles:
ExpressionChangedAfterItHasBeenCheckedError
errorThink about why you need to change the property in the ngAfterViewInit
lifecycle hook. Any other lifecycle that is triggered before ngAfterViewInit/Checked
will work, for example ngOnInit
or ngDoCheck
or ngAfterContentChecked
.
So to fix it move renderWidgetInsideWidgetContainer
to the ngOnInit()
lifecycle hook.
visibility:hidden is the proper syntax, but another way to 'hide' the table is with display:none or dynamically with JQuery:
$('#myTable').hide()
Probably not the most efficient, but think it's a neat way to do it.
class Program
{
static void Main(string[] args)
{
Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "true"));
Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "false"));
}
static Int32 CountAllTheTimesThisStringAppearsInThatString(string orig, string find)
{
var s2 = orig.Replace(find,"");
return (orig.Length - s2.Length) / find.Length;
}
}
You can use the rename.vars
in the gdata
package.
library(gdata)
df <- rename.vars(df, from = "oldname", to = "newname")
This is particularly useful where you have more than one variable name to change or you want to append or pre-pend some text to the variable names, then you can do something like:
df <- rename.vars(df, from = c("old1", "old2", "old3",
to = c("new1", "new2", "new3"))
For an example of appending text to a subset of variables names see: https://stackoverflow.com/a/28870000/180892
This is an direct excerpt from the excellent book 'Thinking in Java' by Bruce Eckel.
[..] Should you use an interface or an abstract class?
Well, an interface gives you the benefits of an abstract class and the benefits of an interface, so if it’s possible to create your base class without any method definitions or member variables you should always prefer interfaces to abstract classes.
In fact, if you know something is going to be a base class, your first choice should be to make it an interface, and only if you’re forced to have method definitions or member variables should you change to an abstract class.
Depending on whether you need absolute paths you may want to take an extra step:
child='/home/smith/Desktop/Test/'
parent=$(dirname "$child")
abs_parent=$(realpath "$parent")
The main difference is that appendChild
is a DOM method and append
is a jQuery method. The second one uses the first as you can see on jQuery source code
append: function() {
return this.domManip(arguments, true, function( elem ) {
if ( this.nodeType === 1 || this.nodeType === 11 || this.nodeType === 9 ) {
this.appendChild( elem );
}
});
},
If you're using jQuery library on your project, you'll be safe always using append
when adding elements to the page.
From the bash manpage:
When bash is invoked as an interactive login shell, or as a non-interactive shell with the
--login
option, it first reads and executes commands from the file/etc/profile
, if that file exists. After reading that file, it looks for~/.bash_profile
,~/.bash_login
, and~/.profile
, in that order, and reads and executes commands from the first one that exists and is readable. The--noprofile
option may be used when the shell is started to inhibit this behavior.When a login shell exits, bash reads and executes commands from the file
~/.bash_logout
, if it exists.When an interactive shell that is not a login shell is started, bash reads and executes commands from
~/.bashrc
, if that file exists. This may be inhibited by using the--norc
option. The--rcfile
file option will force bash to read and execute commands from file instead of~/.bashrc
.
Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc
or .bash_profile
, and then have the other file source the first one.
It is as simple as to Add one dimension, so I was going through the tutorial taught by Siraj Rawal on CNN Code Deployment tutorial, it was working on his terminal, but the same code was not working on my terminal, so I did some research about it and solved, I don't know if that works for you all. Here I have come up with solution;
Unsolved code lines which gives you problem:
if K.image_data_format() == 'channels_first':
x_train = x_train.reshape(x_train.shape[0], 1, img_rows, img_cols)
x_test = x_test.reshape(x_test.shape[0], 1, img_rows, img_cols)
print(x_train.shape)
input_shape = (1, img_rows, img_cols)
else:
x_train = x_train.reshape(x_train.shape[0], img_rows, img_cols)
x_test = x_test.reshape(x_test.shape[0], img_rows, img_cols)
input_shape = (img_rows, img_cols, 1)
Solved Code:

Please share the feedback here if that worked for you.
Since Bootstrap 3 you have to use checkbox-inline and radio-inline classes on the label.
This takes care of vertical alignment.
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
In Bootstrap 4:
to center the child horizontally, use bootstrap-4 class:
justify-content-center
to center the child vertically, use bootstrap-4 class:
align-items-center
but remember don't forget to use d-flex class with these it's a bootstrap-4 utility class, like so
<div class="d-flex justify-content-center align-items-center" style="height:100px;">
<span class="bg-primary">MIDDLE</span>
</div>
Note: make sure to add bootstrap-4 utilities if this code does not work
I know it's not the direct answer to this question but it may help someone
You can write your own equals function:
a == b
Because you're dealing with json, you'll have standard python types: dict
, list
, etc., so you can do hard type checking if type(obj) == 'dict':
, etc.
Rough example (not tested):
def json_equals(jsonA, jsonB):
if type(jsonA) != type(jsonB):
# not equal
return False
if type(jsonA) == dict:
if len(jsonA) != len(jsonB):
return False
for keyA in jsonA:
if keyA not in jsonB or not json_equal(jsonA[keyA], jsonB[keyA]):
return False
elif type(jsonA) == list:
if len(jsonA) != len(jsonB):
return False
for itemA, itemB in zip(jsonA, jsonB):
if not json_equal(itemA, itemB):
return False
else:
return jsonA == jsonB
If you don't care about the actual key, a concise way to iterate over all the Map's values would be to use its values()
method
Map<String, List<String>> myMap;
for ( List<String> stringList : myMap.values() ) {
for ( String myString : stringList ) {
// process the string here
}
}
The values()
method is part of the Map interface and returns a Collection view of the values in the map.
When using Jest 21.2.1, I can see code coverage at the command line and create a coverage directory by passing --coverage
to the Jest script. Below are some examples:
I tend to install Jest locally, in which case the command might look like this:
npx jest --coverage
I assume (though haven't confirmed), that this would also work if I installed Jest globally:
jest --coverage
The very sparse docs are here
When I navigated into the coverage/lcov-report directory I found an index.html file that could be loaded into a browser. It included the information printed at the command line, plus additional information and some graphical output.
First make sure all nuget packages are at the same version across all projects in your solution. e.g. you dont want one project to reference NLog 4.0.0.0 and another project to reference NLog 4.1.0.0. Then try reinstalling nuget packages with
Update-Package -reinstall
I had 3 3rd party assemblies that were referenced by my assembly A and only 2 were included in References by my assembly B which also referenced A.
The missing reference to the 3rd party assembly was added by the update package command, and the error went away.
Here I would like to present another alternative to Flatten function. This may help to understand what is going on internally. The alternative method adds three more code lines. Instead of using
#==========================================Build a Model
model = tf.keras.models.Sequential()
model.add(keras.layers.Flatten(input_shape=(28, 28, 3)))#reshapes to (2352)=28x28x3
model.add(layers.experimental.preprocessing.Rescaling(1./255))#normalize
model.add(keras.layers.Dense(128,activation=tf.nn.relu))
model.add(keras.layers.Dense(2,activation=tf.nn.softmax))
model.build()
model.summary()# summary of the model
we can use
#==========================================Build a Model
tensor = tf.keras.backend.placeholder(dtype=tf.float32, shape=(None, 28, 28, 3))
model = tf.keras.models.Sequential()
model.add(keras.layers.InputLayer(input_tensor=tensor))
model.add(keras.layers.Reshape([2352]))
model.add(layers.experimental.preprocessing.Rescaling(1./255))#normalize
model.add(keras.layers.Dense(128,activation=tf.nn.relu))
model.add(keras.layers.Dense(2,activation=tf.nn.softmax))
model.build()
model.summary()# summary of the model
In the second case, we first create a tensor (using a placeholder) and then create an Input layer. After, we reshape the tensor to flat form. So basically,
Create tensor->Create InputLayer->Reshape == Flatten
Flatten is a convenient function, doing all this automatically. Of course both ways has its specific use cases. Keras provides enough flexibility to manipulate the way you want to create a model.
Drop the parentheses and commas:
myBackupFunction ".." "..." "xx"
And the function should look like this:
function myBackupFunction() {
# Here $1 is the first parameter, $2 the second, etc.
}
You can use simple print statements, or any other way of writing to stdout. You can also invoke the Python debugger anywhere in your tests.
If you use nose to run your tests (which I recommend), it will collect the stdout for each test and only show it to you if the test failed, so you don't have to live with the cluttered output when the tests pass.
nose also has switches to automatically show variables mentioned in asserts, or to invoke the debugger on failed tests. For example -s
(--nocapture
) prevents the capture of stdout.
I was having a similar problem, however my program would crash when I tried to set the text. I was attempting to set the text value from within a class that extends AsyncTask, and that was what was causing the problem.
To resolve it, I moved my setText to the onPostExecute method
protected void onPostExecute(Void result) {
super.onPostExecute(result);
TextView text = (TextView) findViewById(R.id.errorsToday);
text.setText("new string value");
}
Or just use this in your View(Razor page)
@item.ResgistrationhaseDate.ToString(string.Format("dd/MM/yyyy"))
I recommend that don't add date format in your model class
I am using EF 4.0 and WPF and I had similar problem, and .... found the issue that solved it (at least for me) in a very simple way.
Because, like you, I thought it must be simple to update a field in a table (i.e. in your case: Contact) that is referenced to by a foreignkey from another table (i.e. in your case: ContactType).
However, the Error Message: ".... is part of the object's key information and cannot be modified." only appears when you try to update a Primary Key (which wasn't my intention at all).
Had a closer look at the XML code of my EntityModel and found it:
<EntityType Name="Contact">
<Key>
<PropertyRef Name="ID" />
<PropertyRef Name="contactTypeID" /> <!-- This second line caused my problem -->
</Key>
<Property Name="ID" Type="int" Nullable="false" />
...
...
</EntityType>
For some reason (maybe I made some foolish mistake within my database), when Visual Studio autogenerated for me the DataModel from my database, it added in that very table (Contact), where I wanted to update the field (ContactTypeID
) a second PropertyRef
(second line).
I just deleted that second PropertyRef
:
<PropertyRef Name="contactTypeID" />
in both, the store model and the conceptual model and .... issue was solved :-)
Hence, remains like:
<EntityType Name="Contact">
<Key>
<PropertyRef Name="ID" />
</Key>
<Property Name="ID" Type="int" Nullable="false" />
...
...
</EntityType>
Updates and Inserts are now running smoothly like a baby .... :-)
Hence, good idea to check the XML of the datamodel to verify that only your PK is listed as PropertyRef
. Worked for me ... :-)
Here's one way in XSLT 2
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"','''')"/> </xsl:template> </xsl:stylesheet>
Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:variable name="apos">'</xsl:variable> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"',$apos)"/> </xsl:template> </xsl:stylesheet>
Think of "BeforeClass" as a static initializer for your test case - use it for initializing static data - things that do not change across your test cases. You definitely want to be careful about static resources that are not thread safe.
Finally, use the "AfterClass" annotated method to clean up any setup you did in the "BeforeClass" annotated method (unless their self destruction is good enough).
"Before" & "After" are for unit test specific initialization. I typically use these methods to initialize / re-initialize the mocks of my dependencies. Obviously, this initialization is not specific to a unit test, but general to all unit tests.
You need to start the Apache Tomcat services.
Win+R --> sevices.msc
Then, search for Apache Tomcat and right click on it and click on Start. This will start the service and then you'll be able to see Apache Tomcat homepage on the localhost

You could use npm i sweetalert2
Don't forget to add the style to your angular.json
"styles": [
...
"node_modules/sweetalert2/src/sweetalert2.scss"
]
Then just import,
// ES6 Modules or TypeScript
import Swal from 'sweetalert2'
// CommonJS
const Swal = require('sweetalert2')
Boom, you are ready to go.
Swal.fire({
title: 'Are you sure?',
text: 'You will not be able to recover this imaginary file!',
icon: 'warning',
showCancelButton: true,
confirmButtonText: 'Yes, delete it!',
cancelButtonText: 'No, keep it'
}).then((result) => {
if (result.value) {
Swal.fire(
'Deleted!',
'Your imaginary file has been deleted.',
'success'
)
// For more information about handling dismissals please visit
// https://sweetalert2.github.io/#handling-dismissals
} else if (result.dismiss === Swal.DismissReason.cancel) {
Swal.fire(
'Cancelled',
'Your imaginary file is safe :)',
'error'

Try the following date Format.
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter. dateFromString (strDate)
Hope it helps..
Swift 4.1 :
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter.date(from: strDate)
I assume this is *nix?
Use "here document":

For .Net v4.0 I noticed, setting the value of ServicePointManager.SecurityProtocol to (SecurityProtocolType)3072 but before creating the HttpWebRequest object helped.
The most concise method I found can be done using in just one line:
let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`
Explanation
`${...}`
Template literals. Allows for expressions to be converted into a string from within the string itself.
Note: Incompatible with IE.
timeInSeconds/60|0
Takes the seconds and converts in into minutes (/60
). This gives a rational number. From here it is truncated using the bitwise OR (|0
)
timeInSeconds%60
Remainder (modulo). Gives the remainder of the variable divided by 60.
Hours
This method can be expanded to include hours like this:
let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`
Repeating this process, you can even include days.
You can extract the different parts out quite neatly using a regex pattern:
In [11]: df.row.str.extract('(?P<fips>\d{5})((?P<state>[A-Z ]*$)|(?P<county>.*?), (?P<state_code>[A-Z]{2}$))')
Out[11]:
fips 1 state county state_code
0 00000 UNITED STATES UNITED STATES NaN NaN
1 01000 ALABAMA ALABAMA NaN NaN
2 01001 Autauga County, AL NaN Autauga County AL
3 01003 Baldwin County, AL NaN Baldwin County AL
4 01005 Barbour County, AL NaN Barbour County AL
[5 rows x 5 columns]
To explain the somewhat long regex:
(?P<fips>\d{5})
\d
) and names them "fips"
.The next part:
((?P<state>[A-Z ]*$)|(?P<county>.*?), (?P<state_code>[A-Z]{2}$))
Does either (|
) one of two things:
(?P<state>[A-Z ]*$)
*
) of capital letters or spaces ([A-Z ]
) and names this "state"
before the end of the string ($
),or
(?P<county>.*?), (?P<state_code>[A-Z]{2}$))
.*
) thenstate_code
before the end of the string ($
).In the example:
Note that the first two rows hit the "state" (leaving NaN in the county and state_code columns), whilst the last three hit the county, state_code (leaving NaN in the state column).

It is possible to record screen video directly from your phone or tablet if your device is rooted. I'm working on the SCR Screen Recorder app. To the best of my knowledge this is the only app supporting Tegra devices (including Nexus 7) and Android 4.2. At the moment the app records between 9-18fps depending on device but I'm working to improve that. SCR Screen Recorder is still in beta testing phase so feel free to test it and give feedback.
you can use like this situation:
for example, you have a page: http://www.example.com/page.php
then in that page.php, insert this code:
if (!empty($_GET['doaction']) && $_GET['doaction'] == blabla ){
echo '<script>alert("hello");</script>';
}
then, whenever you visit this url: http://www.example.com/page.php?doaction=blabla
then the alert will be automatically called.

After turning on ASP.NET from "Programs and Features > Turn Windows features on or off", you must install ASP.NET from the Windows command prompt. The MIME types don't ever show up, but after doing this command, I noticed these extensions showed up under the IIS web site "Handler Mappings" section of IIS Manager.

I was having the same problem and even though I was styling my button in CSS it would never pick up the border:none
but what worked was adding a style directly on the input button like so:
<div style="text-align:center;">
<input type="submit" class="SubmitButtonClass" style="border:none;" value="" />
</div>
While the syntax is certainly different between Razor (.cshtml
/.vbhtml
) and WebForms (.aspx
/.ascx
), (Razor's being the more concise and modern of the two), nobody has mentioned that while both can be used as View Engines / Templating Engines, traditional ASP.NET Web Forms controls can be used on any .aspx or .ascx files, (even in cohesion with an MVC architecture).
This is relevant in situations where long standing solutions to a problem have been established and packaged into a pluggable component (e.g. a large-file uploading control) and you want to use it in an MVC site. With Razor, you can't do this. However, you can execute all of the same backend-processing that you would use with a traditional ASP.NET architecture with a Web Form view.
Furthermore, ASP.NET web forms views can have Code-Behind files, which allows embedding logic into a separate file that is compiled together with the view. While the software development community is growing to be see tightly coupled architectures and the Smart Client pattern as bad practice, it used to be the main way of doing things and is still very much possible with .aspx/.ascx files. Razor, intentionally, has no such quality.
If you want to pass the form to the controller for validation purposes you can simply pass it as an argument to the method handling the submission. Use the form name, so for the original question it would be something like:
<button ng-click="submit(customerForm)">Save</button>
In my opinion, the accepted answer is confusing, since it uses a DataFrame with only missing values. I also do not like the term position-based for .iloc
and instead, prefer integer location as it is much more descriptive and exactly what .iloc
stands for. The key word is INTEGER - .iloc
needs INTEGERS.
See my extremely detailed blog series on subset selection for more
Because .ix
is deprecated we will only focus on the differences between .loc
and .iloc
.
Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each index. Let's take a look at a sample DataFrame:
df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
'height':[165, 70, 120, 80, 180, 172, 150],
'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
},
index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])
All the words in bold are the labels. The labels, age
, color
, food
, height
, score
and state
are used for the columns. The other labels, Jane
, Nick
, Aaron
, Penelope
, Dean
, Christina
, Cornelia
are used for the index.
The primary ways to select particular rows in a DataFrame are with the .loc
and .iloc
indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.
We will first talk about the .loc
indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length of the DataFrame.
There are three different inputs you can use for .loc
Selecting a single row with .loc with a string
To select a single row of data, place the index label inside of the brackets following .loc
.
df.loc['Penelope']
This returns the row of data as a Series
age 4
color white
food Apple
height 80
score 3.3
state AL
Name: Penelope, dtype: object
Selecting multiple rows with .loc with a list of strings
df.loc[['Cornelia', 'Jane', 'Dean']]
This returns a DataFrame with the rows in the order specified in the list:
Selecting multiple rows with .loc with slice notation
Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.
df.loc['Aaron':'Dean']
Complex slices can be taken in the same manner as Python lists.
Let's now turn to .iloc
. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.
There are three different inputs you can use for .iloc
Selecting a single row with .iloc with an integer
df.iloc[4]
This returns the 5th row (integer location 4) as a Series
age 32
color gray
food Cheese
height 180
score 1.8
state AK
Name: Dean, dtype: object
Selecting multiple rows with .iloc with a list of integers
df.iloc[[2, -2]]
This returns a DataFrame of the third and second to last rows:
Selecting multiple rows with .iloc with slice notation
df.iloc[:5:3]
One excellent ability of both .loc/.iloc
is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.
For example, we can select rows Jane, and Dean with just the columns height, score and state like this:
df.loc[['Jane', 'Dean'], 'height':]
This uses a list of labels for the rows and slice notation for the columns
We can naturally do similar operations with .iloc
using only integers.
df.iloc[[1,4], 2]
Nick Lamb
Dean Cheese
Name: food, dtype: object
.ix
was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.
For instance, if we want to select rows Nick
and Cornelia
along with columns 2 and 4, we could use .loc
by converting the integers to labels with the following:
col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names]
Or alternatively, convert the index labels to integers with the get_loc
index method.
labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]
The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows wher age is above 30 and return just the food
and score
columns we can do the following:
df.loc[df['age'] > 30, ['food', 'score']]
You can replicate this with .iloc
but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:
df.iloc[(df['age'] > 30).values, [2, 4]]
It is possible to use .loc/.iloc
for just column selection. You can select all the rows by using a colon like this:
df.loc[:, 'color':'score':2]
[]
, can select rows and columns too but not simultaneously.Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.
df['food']
Jane Steak
Nick Lamb
Aaron Mango
Penelope Apple
Dean Cheese
Christina Melon
Cornelia Beans
Name: food, dtype: object
Using a list selects multiple columns
df[['food', 'score']]
What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.
df['Penelope':'Christina'] # slice rows by label
df[2:6:2] # slice rows by integer location
The explicitness of .loc/.iloc
for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.
df[3:5, 'color']
TypeError: unhashable type: 'slice'
see this example :
PersonneTest pt=new PersonneTest();
System.out.println(pt.getClass().getDeclaredFields().length);
Field[]x=pt.getClass().getDeclaredFields();
System.out.println(x[1].getName());
python compile on the fly when you run it.
Run a .py file by(linux): python abc.py
Every line that begins with a (
, [
, `, or any operator (/, +, - are the only valid ones), must begin with a semicolon.
func()
;[0].concat(myarr).forEach(func)
;(myarr).forEach(func)
;`hello`.forEach(func)
;/hello/.exec(str)
;+0
;-0
This prevents a
func()[0].concat(myarr).forEach(func)(myarr).forEach(func)`hello`.forEach(func)/hello/.forEach(func)+0-0
monstrocity.
To mention what will happen: brackets will index, parentheses will be treated as function parameters. The backtick would transform into a tagged template, and regex or explicitly signed integers will turn into operators. Of course, you can just add a semicolon to the end of every line. It's good to keep mind though when you're quickly prototyping and are dropping your semicolons.
Also, adding semicolons to the end of every line won't help you with the following, so keep in mind statements like
return // Will automatically insert semicolon, and return undefined.
(1+2);
i // Adds a semicolon
++ // But, if you really intended i++ here, your codebase needs help.
The above case will happen to return/continue/break/++/--. Any linter will catch this with dead-code or ++/-- syntax error (++/-- will never realistically happen).
Finally, if you want file concatenation to work, make sure each file ends with a semicolon. If you're using a bundler program (recommended), it should do this automatically.
Assuming this example HTML:
<input type="text" name="email" id="email" />
<input type="text" name="first_name" id="first_name" />
<input type="text" name="last_name" id="last_name" />
You could have this javascript:
$("#email").bind("change", function(e){
$.getJSON("http://yourwebsite.com/lokup.php?email=" + $("#email").val(),
function(data){
$.each(data, function(i,item){
if (item.field == "first_name") {
$("#first_name").val(item.value);
} else if (item.field == "last_name") {
$("#last_name").val(item.value);
}
});
});
});
Then just you have a PHP script (in this case lookup.php) that takes an email in the query string and returns a JSON formatted array back with the values you want to access. This is the part that actually hits the database to look up the values:
<?php
//look up the record based on email and get the firstname and lastname
...
//build the JSON array for return
$json = array(array('field' => 'first_name',
'value' => $firstName),
array('field' => 'last_name',
'value' => $last_name));
echo json_encode($json );
?>
You'll want to do other things like sanitize the email input, etc, but should get you going in the right direction.
If you get this in Angular.js, then make sure you escape your port number like this:
var Project = $resource(
'http://localhost\\:5648/api/...', {'a':'b'}, {
update: { method: 'PUT' }
}
);
See here for more info on it.
npm was failing for me at scandir
for:
npm install -g webpack
...which might be caused by npm attempting to "modify" files that were potentially locked by other processes as mentioned here and in few other github threads. After force cleaning the cache, verifying cache, running as admin, disabling the AV, etc the solution that actually worked for me was closing any thing that might be placing a lock the files (i.e. restarting my computer).
I hope this helps someone struggling.
JavaScript
If you want to make it case insensitive just add i
at the end of regex:
'Test'.match(/[A-Z]/gi)
//Returns ["T", "e", "s", "t"]
Without i
'Test'.match(/[A-Z]/g)
//Returns ["T"]
my way is this
subjcts is
[{"id":"1","title":"GFATM"},{"id":"2","title":"Court Case"},{"id":"3","title":"Renewal\/Validity"},{"id":"4","title":"Change of Details"},{"id":"5","title":"Student Query"},{"id":"6","title":"Complains"}]
sub is a Input field or whatever you like
Displaying like this
<div ng-if="x.id === sub" ng-repeat=" x in subjcts">{{x.title}}</div>

I faced similar issue while running the datanode. The following steps were useful.
Go to */hadoop_store/hdfs directory where you have created namenode and datanode as sub-directories. (The paths configured in [hadoop_directory]/etc/hadoop/hdfs-site.xml). Use
rm -r namenode
rm -r datanode
In */hadoop_store/hdfs directory use
sudo mkdir namenode
sudo mkdir datanode
In case of permission issue, use
chmod -R 755 namenode
chmod -R 755 datanode
In [hadoop_directory]/bin use
hadoop namenode -format (To format your namenode)
Simple way in Java
public void resize(String inputImagePath,
String outputImagePath, int scaledWidth, int scaledHeight)
throws IOException {
// reads input image
File inputFile = new File(inputImagePath);
BufferedImage inputImage = ImageIO.read(inputFile);
// creates output image
BufferedImage outputImage = new BufferedImage(scaledWidth,
scaledHeight, inputImage.getType());
// scales the input image to the output image
Graphics2D g2d = outputImage.createGraphics();
g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
g2d.dispose();
// extracts extension of output file
String formatName = outputImagePath.substring(outputImagePath
.lastIndexOf(".") + 1);
// writes to output file
ImageIO.write(outputImage, formatName, new File(outputImagePath));
}
Posed question
Responding to the question 'what metric should be used for multi-class classification with imbalanced data': Macro-F1-measure. Macro Precision and Macro Recall can be also used, but they are not so easily interpretable as for binary classificaion, they are already incorporated into F-measure, and excess metrics complicate methods comparison, parameters tuning, and so on.
Micro averaging are sensitive to class imbalance: if your method, for example, works good for the most common labels and totally messes others, micro-averaged metrics show good results.
Weighting averaging isn't well suited for imbalanced data, because it weights by counts of labels. Moreover, it is too hardly interpretable and unpopular: for instance, there is no mention of such an averaging in the following very detailed survey I strongly recommend to look through:
Sokolova, Marina, and Guy Lapalme. "A systematic analysis of performance measures for classification tasks." Information Processing & Management 45.4 (2009): 427-437.
Application-specific question
However, returning to your task, I'd research 2 topics:
Commonly used metrics. As I can infer after looking through literature, there are 2 main evaluation metrics:
Yu, April, and Daryl Chang. "Multiclass Sentiment Prediction using Yelp Business."
(link) - note that the authors work with almost the same distribution of ratings, see Figure 5.
Pang, Bo, and Lillian Lee. "Seeing stars: Exploiting class relationships for sentiment categorization with respect to rating scales." Proceedings of the 43rd Annual Meeting on Association for Computational Linguistics. Association for Computational Linguistics, 2005.
(link)
Lee, Moontae, and R. Grafe. "Multiclass sentiment analysis with restaurant reviews." Final Projects from CS N 224 (2010).
(link) - they explore both accuracy and MSE, considering the latter to be better
Pappas, Nikolaos, Rue Marconi, and Andrei Popescu-Belis. "Explaining the Stars: Weighted Multiple-Instance Learning for Aspect-Based Sentiment Analysis." Proceedings of the 2014 Conference on Empirical Methods In Natural Language Processing. No. EPFL-CONF-200899. 2014.
(link) - they utilize scikit-learn for evaluation and baseline approaches and state that their code is available; however, I can't find it, so if you need it, write a letter to the authors, the work is pretty new and seems to be written in Python.
Cost of different errors. If you care more about avoiding gross blunders, e.g. assinging 1-star to 5-star review or something like that, look at MSE; if difference matters, but not so much, try MAE, since it doesn't square diff; otherwise stay with Accuracy.
About approaches, not metrics
Try regression approaches, e.g. SVR, since they generally outperforms Multiclass classifiers like SVC or OVA SVM.
I use this to avoid negative interval.
var seconds = (date1< date2)? (date2- date1).TotalSeconds: (date1 - date2).TotalSeconds;
you can use winhttprequest object instead of internet explorer as it's good to load data excluding pictures n advertisement instead of downloading full webpage including advertisement n pictures those make internet explorer object heavy compare to winhttpRequest object.
I think this is closer to the answer you're looking for:
<input type="file">
$file = $(file);
var filename = fileElement[0].files[0].name;
Activity
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableLayout
android:id="@+id/mytable"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TableLayout>
</HorizontalScrollView>
Your Class
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_testtable);
table = (TableLayout)findViewById(R.id.mytable);
showTableLayout();
}
public void showTableLayout(){
Date date = new Date();
int rows = 80;
int colums = 10;
table.setStretchAllColumns(true);
table.bringToFront();
for(int i = 0; i < rows; i++){
TableRow tr = new TableRow(this);
for(int j = 0; j < colums; j++)
{
TextView txtGeneric = new TextView(this);
txtGeneric.setTextSize(18);
txtGeneric.setText( dateFormat.format(date) + "\t\t\t\t" );
tr.addView(txtGeneric);
/*txtGeneric.setHeight(30); txtGeneric.setWidth(50); txtGeneric.setTextColor(Color.BLUE);*/
}
table.addView(tr);
}
}
It works for me thank you. I had this issue when I installed .Net Framework 4.7.1, somehow DbProviderFactories
settings under System.Data
in machine config got wiped-out. It started working after adding the necessary configuration settings as shown below DataProviderFactories
<system.data>
<DbProviderFactories>

This would have worked too. The first quoted pair are interpreted as a window title name in the start command.

I'm not sure if this is quite what you're looking for but I've had a lot of success using an HTML to Postscript converter html2ps to create postscript copies of web pages, which I then convert to .gif or .pngs
This doesn't produce exact screenshot quality that you'd get from a web browser and doesn't handle complicated things like flash or css all that well, but the advantage is that you can run it on the web server.
(I use it to create thumbnails of user created content, for navigation)
I can't disagree with the spirit of the accepted answer strongly enough. "A tool of last resort"? Far from it!
The way I see it, one of the strongest features of C++ compared to C and to some other similar languages is the ability to express constraints so that they can be checked at compile time and accidental misuse can be prevented. So when designing a structure, ask yourself what operations it should permit. All the other uses should be forbidden, and it's best if such restrictions can be implemented statically (at compile time) so that misuse results in a compilation failure.
So when one needs an array, the answers to the following questions specify its behavior: 1. Is its size a) dynamic at runtime, or b) static, but only known at runtime, or c) static and known at compile time? 2. Can the array be allocated on the stack or not?
And based on the answers, this is what I see as the best data structure for such an array:
Dynamic | Runtime static | Static
Stack std::vector unique_ptr<T[]> std::array
Heap std::vector unique_ptr<T[]> unique_ptr<std::array>
Yep, I think unique_ptr<std::array>
should also be considered, and neither is a tool of last resort. Just think what fits best with your algorithm.
All of these are compatible with plain C APIs via the raw pointer to data array (vector.data()
/ array.data()
/ uniquePtr.get()
).
P. S. Apart from the above considerations, there's also one of ownership: std::array
and std::vector
have value semantics (have native support for copying and passing by value), while unique_ptr<T[]>
can only be moved (enforces single ownership). Either can be useful in different scenarios. On the contrary, plain static arrays (int[N]
) and plain dynamic arrays (new int[10]
) offer neither and thus should be avoided if possible - which should be possible in the vast majority of cases. If that wasn't enough, plain dynamic arrays also offer no way to query their size - extra opportunity for memory corruptions and security holes.
The most likely cause is an error in mysql_query()
. Have you checked to make sure it worked? Output the value of $result
and mysql_error()
. You may have misspelled something, selected the wrong database, have a permissions issue, etc. So:
$id = (int)$_GET['id']; // this also sanitizes it
$sql = "SELECT * FROM student WHERE idno = $id";
$result = mysql_query($sql);
if (!$result) {
die("Error running $sql: " . mysql_error());
}
Sanitizing $_GET['id']
is really important. You can use mysql_real_escape_string()
but casting it to an int
is sufficient for integers. Basically you want to avoid SQL injection.
My turn:
https://play.golang.org/p/RifHKsX7Puh
package main
import (
"fmt"
"time"
)
func main() {
var n int = 77
v := time.Duration( 1.15 * float64(n) ) * time.Second
fmt.Printf("%v %T", v, v)
}
It helps to remember the simple fact, that underlyingly the time.Duration is a mere int64, which holds nanoseconds value.
This way, conversion to/from time.Duration becomes a formality. Just remember:
Bogobogosort. Yes, it's a thing. to Bogobogosort, you Bogosort the first element. Check to see if that one element is sorted. Being one element, it will be. Then you add the second element, and Bogosort those two until it's sorted. Then you add one more element, then Bogosort. Continue adding elements and Bogosorting until you have finally done every element. This was designed never to succeed with any sizable list before the heat death of the universe.
You can specify a callback function:
$(selector).fadeOut('slow', function() {
// will be called when the element finishes fading out
// if selector matches multiple elements it will be called once for each
});
I think it suffices to hand the data over directly:
$("#inputhidden").select2("data", data, true);
Note that the second parameter seems to indicate that a refresh is desired.
Thanks to @Bergi for help with this.
If that doesn't automatically update you could either try calling it's updateResults method directly.
$("#inputhidden").select2("updateResults");
Or trigger it indirectly by sending a trigger to the "input.select2-input" like so:
var search = $("#inputhidden input.select2-input");
search.trigger("input");
try this:
declare @foo varchar(7),
@oldFoo varchar(7)

The problem is that your PATH does not include the location of the node executable.
You can likely run node as "/usr/local/bin/node

You can add that location to your path by running the following command to add a single line to your bashrc file:

400 Bad Request will be returned if you attempt to:
Personally, I would print them to a file using Perl or Python in the format
<COL_NAME>: <COL_VAL>
for each row so that the file has as many lines as there are columns. Then I'd do a diff
between the two files, assuming you are on Unix or compare them using some equivalent utilty on another OS. If you have multiple recordsets (i.e. more than one row), I would prepend to each file row and then the file would have NUM_DB_ROWS * NUM_COLS lines

This is about the best you can do:
if (!mail(...)) {
// Reschedule for later try or panic appropriately!
}
http://php.net/manual/en/function.mail.php
mail()
returnsTRUE
if the mail was successfully accepted for delivery,FALSE
otherwise.It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.
If you need to suppress warnings, you can use:
if (!@mail(...))
Be careful though about using the @
operator without appropriate checks as to whether something succeed or not.
If mail()
errors are not suppressible (weird, but can't test it right now), you could:
a) turn off errors temporarily:
$errLevel = error_reporting(E_ALL ^ E_NOTICE); // suppress NOTICEs
mail(...);
error_reporting($errLevel); // restore old error levels
b) use a different mailer, as suggested by fire and Mike.
If mail()
turns out to be too flaky and inflexible, I'd look into b). Turning off errors is making debugging harder and is generally ungood.
With Java 8 you have several options, combining method references and the built-in comparing

Collections.sort(list, comparing(CustomObject::getId));
//or
list.sort(comparing(CustomObject::getId));

One of the most significant JIT optimizations is method inlining. Java can even inline virtual methods if it can guarantee runtime correctness. This kind of optimization usually cannot be performed by standard static compilers because it needs whole-program analysis, which is hard because of separate compilation (in contrast, JIT has all the program available to it). Method inlining improves other optimizations, giving larger code blocks to optimize.
Standard memory allocation in Java/C# is also faster, and deallocation (GC) is not much slower, but only less deterministic.

Here is a sample using pysftp and a private key.
import pysftp
def upload_file(file_path):
private_key = "~/.ssh/your-key.pem" # can use password keyword in Connection instead
srv = pysftp.Connection(host="your-host", username="user-name", private_key=private_key)
srv.chdir('/var/web/public_files/media/uploads') # change directory on remote server
srv.put(file_path) # To download a file, replace put with get
srv.close() # Close connection
pysftp is an easy to use sftp module that utilizes paramiko and pycrypto. It provides a simple interface to sftp.. Other things that you can do with pysftp which are quite useful:
data = srv.listdir() # Get the directory and file listing in a list
srv.get(file_path) # Download a file from remote server
srv.execute('pwd') # Execute a command on the server

String
A String instance is immutable, that is, we cannot change it after it was created. If we perform any operation on a String it will return a new instance (creates a new instance in memory) instead of modifying the existing instance value.
StringBuilder
StringBuilder is mutable, that is, if we perform any operation on StringBuilder it will update the existing instance value and it will not create new instance.
I love how this is explained in the article Cool performance features of EclipseLink 2.5
Indexing Foreign Keys
The first feature is auto indexing of foreign keys. Most people incorrectly assume that databases index foreign keys by default. Well, they don't. Primary keys are auto indexed, but foreign keys are not. This means any query based on the foreign key will be doing full table scans. This is any OneToMany, ManyToMany or ElementCollection relationship, as well as many OneToOne relationships, and most queries on any relationship involving joins or object comparisons. This can be a major perform issue, and you should always index your foreign keys fields.
Laravel's Autoload is a bit different:
1) It will in fact use Composer for some stuff
2) It will call Composer with the optimize flag
3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php
4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.
std
namespace (where features of the C++ Standard Library, such as string
or vector
, are declared).After you write this instruction, if the compiler sees string
it will know that you may be referring to std::string
, and if it sees vector
, it will know that you may be referring to std::vector
. (Provided that you have included in your compilation unit the header files where they are defined, of course.)
If you don't write it, when the compiler sees string
or vector
it will not know what you are refering to. You will need to explicitly tell it std::string
or std::vector
, and if you don't, you will get a compile error.
select true from tablename where condition limit 1;
I believe that this is the query that postgres uses for checking foreign keys.
In your case, you could do this in one go too:

Instead of changing CSS values one by one I would suggest to use LESS. Bootstrap has LESS version on Github: https://github.com/twbs/bootstrap
LESS allows you to define variables to change colors which makes it so much more convenient. Define color once and LESS compiles CSS file that changes the values globally. Saves time and effort.
Also, for posterity -- Clang (like GCC) accepts the -x
switch to set the language of the input files, for example,
$ clang -x c++ some_random_file.txt
This mailing list thread explains the difference between clang
and clang++
well: Difference between clang and clang++
Use Math.Round and specify the number of decimal places.
Math.Round(pay,2);
Math.Round Method (Double, Int32)
Rounds a double-precision floating-point value to a specified number of fractional digits.
Or Math.Round Method (Decimal, Int32)
Rounds a decimal value to a specified number of fractional digits.
If you have dynamic element ID where you need to assign the dynamic value, you may use this:
//element_id = you dynamic id.
//dynamic_val = you dynamic value.
let _el = document.getElementById(element_id);
_el.value = dynamic_val.toString();
This works for me.
Basically, if you specify a files
parameter (a dictionary), then requests
will send a multipart/form-data
POST instead of a application/x-www-form-urlencoded
POST. You are not limited to using actual files in that dictionary, however:
>>> import requests
>>> response = requests.post('http://httpbin.org/post', files=dict(foo='bar'))
>>> response.status_code
200
and httpbin.org lets you know what headers you posted with; in response.json()
we have:
>>> from pprint import pprint
>>> pprint(response.json()['headers'])
{'Accept': '*/*',
'Accept-Encoding': 'gzip, deflate',
'Connection': 'close',
'Content-Length': '141',
'Content-Type': 'multipart/form-data; '
'boundary=c7cbfdd911b4e720f1dd8f479c50bc7f',
'Host': 'httpbin.org',
'User-Agent': 'python-requests/2.21.0'}
Better still, you can further control the filename, content type and additional headers for each part by using a tuple instead of a single string or bytes object. The tuple is expected to contain between 2 and 4 elements; the filename, the content, optionally a content type, and an optional dictionary of further headers.
I'd use the tuple form with None
as the filename, so that the filename="..."
parameter is dropped from the request for those parts:
>>> files = {'foo': 'bar'}
>>> print(requests.Request('POST', 'http://httpbin.org/post', files=files).prepare().body.decode('utf8'))
--bb3f05a247b43eede27a124ef8b968c5
Content-Disposition: form-data; name="foo"; filename="foo"
bar
--bb3f05a247b43eede27a124ef8b968c5--
>>> files = {'foo': (None, 'bar')}
>>> print(requests.Request('POST', 'http://httpbin.org/post', files=files).prepare().body.decode('utf8'))
--d5ca8c90a869c5ae31f70fa3ddb23c76
Content-Disposition: form-data; name="foo"
bar
--d5ca8c90a869c5ae31f70fa3ddb23c76--
files
can also be a list of two-value tuples, if you need ordering and/or multiple fields with the same name:
requests.post(
'http://requestb.in/xucj9exu',
files=(
('foo', (None, 'bar')),
('foo', (None, 'baz')),
('spam', (None, 'eggs')),
)
)
If you specify both files
and data
, then it depends on the value of data
what will be used to create the POST body. If data
is a string, only it willl be used; otherwise both data
and files
are used, with the elements in data
listed first.
There is also the excellent requests-toolbelt
project, which includes advanced Multipart support. It takes field definitions in the same format as the files
parameter, but unlike requests
, it defaults to not setting a filename parameter. In addition, it can stream the request from open file objects, where requests
will first construct the request body in memory:
from requests_toolbelt.multipart.encoder import MultipartEncoder
mp_encoder = MultipartEncoder(
fields={
'foo': 'bar',
# plain file object, no filename or mime type produces a
# Content-Disposition header with just the part name
'spam': ('spam.txt', open('spam.txt', 'rb'), 'text/plain'),
}
)
r = requests.post(
'http://httpbin.org/post',
data=mp_encoder, # The MultipartEncoder is posted as data, don't use files=...!
# The MultipartEncoder provides the content-type header with the boundary:
headers={'Content-Type': mp_encoder.content_type}
)
Fields follow the same conventions; use a tuple with between 2 and 4 elements to add a filename, part mime-type or extra headers. Unlike the files
parameter, no attempt is made to find a default filename
value if you don't use a tuple.
You can bulk import all aliases from one keystore to another:
keytool -importkeystore -srckeystore source.jks -destkeystore dest.jks
Escape dot. Sample command will be.
grep '0\.00'
Instead of handcranking your models try using something like the Json2csharp.com website. Paste In an example JSON response, the fuller the better and then pull in the resultant generated classes. This, at least, takes away some moving parts, will get you the shape of the JSON in csharp giving the serialiser an easier time and you shouldnt have to add attributes.
Just get it working and then make amendments to your class names, to conform to your naming conventions, and add in attributes later.
EDIT: Ok after a little messing around I have successfully deserialised the result into a List of Job (I used Json2csharp.com to create the class for me)
public class Job
{
public string id { get; set; }
public string position_title { get; set; }
public string organization_name { get; set; }
public string rate_interval_code { get; set; }
public int minimum { get; set; }
public int maximum { get; set; }
public string start_date { get; set; }
public string end_date { get; set; }
public List<string> locations { get; set; }
public string url { get; set; }
}
And an edit to your code:
List<Job> model = null;
var client = new HttpClient();
var task = client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs")
.ContinueWith((taskwithresponse) =>
{
var response = taskwithresponse.Result;
var jsonString = response.Content.ReadAsStringAsync();
jsonString.Wait();
model = JsonConvert.DeserializeObject<List<Job>>(jsonString.Result);
});
task.Wait();
This means you can get rid of your containing object. Its worth noting that this isn't a Task related issue but rather a deserialisation issue.
EDIT 2:
There is a way to take a JSON object and generate classes in Visual Studio. Simply copy the JSON of choice and then Edit> Paste Special > Paste JSON as Classes. A whole page is devoted to this here:
http://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special-JSON-And-Xml/
You can use
../
to mean up one level. If you have a page called page2.html in the same folder as page.html then the relative path is:
page2.html.
If you have page2.html at the same level with folder then the path is:
../page2.html
Use the below code to find the count of number of matches that the regex finds in your input
Pattern p = Pattern.compile(regex, Pattern.MULTILINE | Pattern.DOTALL);// "regex" here indicates your predefined regex.
Matcher m = p.matcher(pattern); // "pattern" indicates your string to match the pattern against with
boolean b = m.matches();
if(b)
count++;
while (m.find())
count++;
This is a generalized code not specific one though, tailor it to suit your need
Please feel free to correct me if there is any mistake.
Just pass the object reference to the following function and you will get the index
function thisindex(elm)
{
var the_li = elm;
var the_ul = elm.parentNode;
var li_list = the_ul.childNodes;
var count = 0; // Tracks the index of LI nodes
// Step through all the child nodes of the UL
for( var i = 0; i < li_list.length; i++ )
{
var node = li_list.item(i);
if( node )
{
// Check to see if the node is a LI
if( node.nodeName == "LI" )
{
// Increment the count of LI nodes
count++;
// Check to see if this node is the one passed in
if( the_li == node )
{
// If so, alert the current count
alert(count-1);
}
}
}
}
}
public func jsonPrint(_ o: NSObject, spacing: String = "", after: String = "", before: String = "") {
let newSpacing = spacing + " "
if o.isArray() {
print(before + "[")
if let a = o as? Array<NSObject> {
for object in a {
jsonPrint(object, spacing: newSpacing, after: object == a.last! ? "" : ",", before: newSpacing)
}
}
print(spacing + "]" + after)
} else {
if o.isDictionary() {
print(before + "{")
if let a = o as? Dictionary<NSObject, NSObject> {
for (key, val) in a {

}
}
print(spacing + "}" + after)
} else {
print(before + o.description + after)
}
}
}
This one is pretty close to original Objective-C print style

When you define a layout and view on XML, you can specify the layout width and height of a view to either be wrap content, or fill parent. Taking up half of the area is a bit harder, but if you had something you wanted on the other half you could do something like the following.
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:layout_height="fill_parent"
android:layout_width="0dp"
android:layout_weight="1"/>
<ImageView android:layout_height="fill_parent"
android:layout_width="0dp"
android:layout_weight="1"/>
</LinearLayout>
Giving two things the same weight means that they will stretch to take up the same proportion of the screen. For more info on layouts, see the dev docs.
The key error generally comes if the key doesn't match any of the dataframe column name 'exactly':
You could also try:
import csv
import pandas as pd
import re
with open (filename, "r") as file:
df = pd.read_csv(file, delimiter = ",")
df.columns = ((df.columns.str).replace("^ ","")).str.replace(" $","")
print(df.columns)
Static inner class cannot access non-static members of enclosing class. It can directly access static members (instance field and methods) of enclosing class same like the procedural style of getting value without creating object.
Static inner class can declare both static and non-static members. The static methods have access to static members of main class. However, it cannot access non-static inner class members. To access members of non-static inner class, it has to create object of non-static inner class.
Non-static inner class cannot declare static field and static methods. It has to be declared in either static or top level types. You will get this error on doing so saying "static fields only be declared in static or top level types".
Non-static inner class can access both static and non-static members of enclosing class in procedural style of getting value, but it cannot access members of static inner class.
The enclosing class cannot access members of inner classes until it creates an object of inner classes. IF main class in accessing members of non-static class it can create object of non-static inner class.
If main class in accessing members of static inner class it has two cases:

It's important to match which version of react-navigation library you're using to the solution as they're all different. For those still using react-navigation v1.0.0 for some reason like me, both these worked:
For disabling/hiding header on individual screens:
const AppScreens = StackNavigator(
{
Main: { screen: Main, navigationOptions: { header: null } },
Login: { screen: Login },
Profile: { screen: Profile, navigationOptions: { header: null } },
});
For disabling/hiding all screens at once, use this:
const AppScreens = StackNavigator(
{
Main: { screen: Main},
Login: { screen: Login },
Profile: { screen: Profile },
},
{
headerMode: 'none',
}
);
void input_from_key_board(int &ri, int &ci)
{
char ch = 'x';
if (_kbhit())
{
ch = _getch();
if (ch == -32)
{
ch = _getch();
switch (ch)
{
case 72: { ri--; break; }
case 80: { ri++; break; }
case 77: { ci++; break; }
case 75: { ci--; break; }
}
}
else if (ch == '\r'){ gotoRowCol(ri++, ci -= ci); }
else if (ch == '\t'){ gotoRowCol(ri, ci += 5); }
else if (ch == 27) { system("ipconfig"); }
else if (ch == 8){ cout << " "; gotoRowCol(ri, --ci); if (ci <= 0)gotoRowCol(ri--, ci); }
else { cout << ch; gotoRowCol(ri, ci++); }
gotoRowCol(ri, ci);
}
}
For those of you running into the ever so common error "fatal: remote origin already exists.", or when trying to remove origin and you get "error: could not remove config section remote.origin", what you need to do is to set the origin manually.
Window's POSH~Git for Windows PowerShell (and GitHub for Windows' app) has a problem with this.
I ran into this, like I do so often, again when setting up my octopress. So, here's how I got it working.
First, check your remotes:
C:\gd\code\octopress [source +2 ~3 -0 !]> git remote -v
octopress https://github.com/imathis/octopress.git (fetch)
octopress https://github.com/imathis/octopress.git (push)
origin
You'll first note that my origin has no url. Any attempt to remove it, rename it, etc all fails.
So, change the url manually:
git remote set-url --add origin https://github.com/eduncan911/eduncan911.github.io.git
Then you can confirm it worked by running git remote -v
again:
C:\gd\code\octopress [source +2 ~3 -0 !]> git remote -v
octopress https://github.com/imathis/octopress.git (fetch)
octopress https://github.com/imathis/octopress.git (push)
origin https://github.com/eduncan911/eduncan911.github.io.git (fetch)
origin https://github.com/eduncan911/eduncan911.github.io.git (push)
This has fixed dozens of git repos I've had issues with, GitHub, BitBucket GitLab, etc.
Here is another dirty hack :)

Look at here: http://blog-mstechnology.blogspot.de/2010/06/throw-vs-throw-ex.html
Throw:
try
{
// do some operation that can fail
}
catch (Exception ex)
{
// do some local cleanup
throw;
}
It preserve the Stack information with Exception
This is called as "Rethrow"
If want to throw new exception,
throw new ApplicationException("operation failed!");
Throw Ex:
try
{
// do some operation that can fail
}
catch (Exception ex)
{
// do some local cleanup
throw ex;
}
It Won't Send Stack information with Exception
This is called as "Breaking the Stack"
If want to throw new exception,
throw new ApplicationException("operation failed!",ex);
Here is an answer in Java:
public static boolean isEven (Integer Number) {
Pattern number = Pattern.compile("^.*?(?:[02]|8|(?:6|4))$");
String num = Number.toString(Number);
Boolean numbr = new Boolean(number.matcher(num).matches());
return numbr.booleanValue();
}
COPY table_name FROM 'path/to/data.csv' DELIMITER ',' CSV HEADER;
You need to convert your private key to PKCS8 format using following command:
openssl pkcs8 -topk8 -inform PEM -outform DER -in private_key_file -nocrypt > pkcs8_key
After this your java program can read it.
For at DataFrame one can simply type
head(data, num=10L)
to get the first 10 for example.
For a data.frame one can simply type
head(data, 10)
to get the first 10.
You can convert a string to a file object using io.StringIO
and then pass that to the csv
module:
from io import StringIO
import csv
scsv = """text,with,Polish,non-Latin,letters
1,2,3,4,5,6
a,b,c,d,e,f
ges,zólty,waz,idzie,waska,drózka,
"""
f = StringIO(scsv)
reader = csv.reader(f, delimiter=',')
for row in reader:
print('\t'.join(row))
simpler version with split()
on newlines:
reader = csv.reader(scsv.split('\n'), delimiter=',')
for row in reader:
print('\t'.join(row))
Or you can simply split()
this string into lines using \n
as separator, and then split()
each line into values, but this way you must be aware of quoting, so using csv
module is preferred.
On Python 2 you have to import StringIO
as
from StringIO import StringIO
instead.
PUT ing
PUT /binders/{id}/docs
Create or update, and relate a single document to a binder
e.g.:
PUT /binders/1/docs HTTP/1.1
{
"docNumber" : 1
}
PATCH ing
PATCH /docs
Create docs if they do not exist and relate them to binders
e.g.:
PATCH /docs HTTP/1.1
[
{ "op" : "add", "path" : "/binder/1/docs", "value" : { "doc_number" : 1 } },
{ "op" : "add", "path" : "/binder/8/docs", "value" : { "doc_number" : 8 } },
{ "op" : "add", "path" : "/binder/3/docs", "value" : { "doc_number" : 6 } }

I'll include additional insights later, but in the meantime if you want to, have a look at RFC 5789, RFC 6902 and William Durand's Please. Don't Patch Like an Idiot blog entry.
1) Find out where java is installed on your drive, open a cmd prompt, go to that location and run ".\java -version" to find out the exact version. Or, quite simply, check the add/remove module in the control panel.
2) After you actually install jdk 7, you need to tell Eclipse about it. Window -> Preferences -> Java -> Installed JREs.
