This worked for me.

.alert:not(:first-child){
    margin: 30px;
}

align-content

align-content controls the cross-axis (i.e. vertical direction if the flex-direction is row, and horizontal if the flex-direction is column) positioning of multiple lines relative to each other.

(Think lines of a paragraph being vertically spread out, stacked toward the top, stacked toward the bottom. This is under a flex-direction row paradigm).

align-items

align-items controls the cross-axis of an individual line of flex elements.

(Think how an individual line of a paragraph is aligned, if it contains some normal text and some taller text like math equations. In that case, will it be the bottom, top, or center of each type of text in a line that will be aligned?)

Add a background-attachment line:

#background {
    background-attachment:fixed;
    width: 100%; 
    height: 100%; 
    position: absolute; 
    margin-left: 0px; 
    margin-top: 0px; 
    z-index: 0;
}

.stretch {
    width:100%;
    height:auto;
}

You need to use quote marks.

font-family: "Comic Sans MS", cursive, sans-serif;

Although you really really shouldn't use comic sans. The font has massive stigma attached to it's use; it's not seen as professional at all.

In my case, the issue was that I had another element in the center of the div with a conflicting z-index.

.wrapper {_x000D_
  color: white;_x000D_
  width: 320px;_x000D_
  position: relative;_x000D_
  border: 1px dashed gray;_x000D_

  /* This z-index override is needed to display on top of the other_x000D_
     div. Or, just swap the order of the HTML tags. */_x000D_
  z-index: 1;_x000D_

_x000D_

Try to add display:inline; to the CSS property of a button.

If you want to be able to choose from different solutions, in addition to the given answers...

An alternative method is to give the container a width of 0 and to make sure overflow is visible. Then each word will overflow out of it and will be on its own line.

div {_x000D_
  width: 0;_x000D_
  overflow: visible;_x000D_
}

<div>Short Word</div>_x000D_
<hr>_x000D_
<div>Gargantuan Word</div>

Or you can use one of those newly proposed width values, provided those still exist by the time you read this.

div {_x000D_
  width: min-intrinsic;       /* old Chrome, Safari */_x000D_
  width: -webkit-min-content; /* less old Chrome, Safari */_x000D_
  width: -moz-min-content;    /* current Firefox */_x000D_
  width: min-content;         /* current Chrome, Safari; not IE or Edge */_x000D_
}

<div>Short Word</div>_x000D_
<hr>_x000D_
<div>Gargantuan Word</div>

Margin: 0 auto; is the correct answer for horizontal centering only. For centering both ways something like this will work, using jquery:

var cenBtn = function() {
   var W = $(window).width();
   var H = $(window).height();
   var BtnW = insert button width;
   var BtnH = insert button height;
   var LeftOff = (W / 2) - (BtnW / 2);
   var TopOff = (H / 2) - (BtnH /2);
       $("#buttonID").css({left: LeftOff, top: TopOff});
};

$(window).bind("load, resize", cenBtn);

Update ... five years later, one could use flexbox on the parent DIV element to easily center the button both horizontally and vertically.

Use the pointer-events property.

The idea here is to overlay an element over the native drop down arrow (to create our custom one) and then disallow pointer events on it. [see this post]

Here is a working FIDDLE using this method.

Also, in this SO answer I discussed this and another method in greater detail.

Try this JS function, passing the span element as argument:

function isEllipsisActive(e) {
     return (e.offsetWidth < e.scrollWidth);
}

Also, in your html, remember to delete all blanks / line feeds / tabs between the closing tag and the opening tag.

<img src='a.png' /> <img src='b.png' /> will always display a space between the images even if the border attribute is set to 0, whereas <img src='a.png' /><img src='b.png' /> will not.

To adapt @luke flournoy's brilliant answer - and if you're not using th in your table, here's all the CSS you need to make a rounded table:

.my_table{
border-collapse: separate;
border-spacing: 0;
border: 1px solid grey;
border-radius: 10px;
-moz-border-radius: 10px;
-webkit-border-radius: 10px;
}

.my_table tr:first-of-type {
  border-top-left-radius: 10px;
}

.my_table tr:first-of-type td:last-of-type {
  border-top-right-radius: 10px;
}

.my_table tr:last-of-type td:first-of-type {
  border-bottom-left-radius: 10px;
}

.my_table tr:last-of-type td:last-of-type {
  border-bottom-right-radius: 10px;
}

Try this, add this lines in the web.config.

<system.webServer>
  <staticContent>
     <mimeMap fileExtension=".woff" mimeType="application/octet-stream" />
  </staticContent>
</system.webServer>

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

.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

In most browsers, the title attribute will render as a tooltip, and is generally flexible as to what sorts of elements it'll work with.

<span title="This will show as a tooltip">Mouse over for a tooltip!</span>
<a href="http://www.stackoverflow.com" title="Link to stackoverflow.com">stackoverflow.com</a>
<img src="something.png" alt="Something" title="Something">

All of those will render tooltips in most every browser.

By default, IUSR account is used for anonymous user.

All you need to do is:

IIS -> Authentication --> Set Anonymous Authentication to Application Pool Identity.

Problem solved :)

I picked up the content using JavaScript and created a window that I could print in stead...

Short answer is: No, it's not possible to prevent CSS inheritance. You can only override the styles that are set on the parents. See the spec:

Every element in an HTML document will inherit all inheritable properties from its parent except the root element (html), which doesn’t have a parent. -W3C

Apart from overriding every single inherited property. You can also use initial keyword, e.g. color: initial;. It also can be used together with all, e.g. all: initial;, that will reset all properties at once. Example:

.container {_x000D_
  color: blue;_x000D_
  font-style: italic;_x000D_
}_x000D_
.initial {_x000D_
  all: initial;_x000D_
}

<div class="container">_x000D_
  The quick brown <span class="initial">fox</span> jumps over the lazy dog_x000D_
</div>

Browser support tables according to Can I use...

• all (Currently no support in both IE and Edge, others are good)
• initial (Currently no support in IE, others are good)

You may find it useful by using direct children selector > in some cases. Example:

.list > li {_x000D_
  border: 1px solid red;_x000D_
  color: blue;_x000D_
}

<ul class="list">_x000D_
  <li>_x000D_
    <span>HEADING 1</span>_x000D_
    <ul>_x000D_
      <li>sub-heading A</li>_x000D_
      <li>sub-heading B</li>_x000D_
    </ul>_x000D_
  </li>_x000D_
  <li>_x000D_
    <span>HEADING 2</span>_x000D_
    <ul>_x000D_
      <li>sub-heading A</li>_x000D_
      <li>sub-heading B</li>_x000D_
    </ul>_x000D_
  </li>_x000D_
</ul>

The border style has been applied only to the direct children <li>s, as border is an non-inherited property. But text color has been applied to all the children, as color is an inherited property.

Therefore, > selector would be only useful with non-inherited properties, when it comes to preventing inheritance.

As shown above, the problem is the margin preceding the <p> tag in rendering time. Not an elegant solution but effective would be to decrease the top margin.

p { margin-top: -20px; }

Yes you use this

<a href="#google"></a>

<div id="google"></div>

But this does not create a smooth scroll just so you know.

You can also add in your CSS

html {
  scroll-behavior: smooth;
}

To get your radio button to list horizontally , just add

RepeatDirection="Horizontal"

to your .aspx file where the asp:radiobuttonlist is being declared.

Check JavaScript Cookies on W3Schools.com for setting and getting cookie values via JS.

Just use the setCookie and getCookie methods mentioned there.

So, the code will look something like:

<script>
function setCookie(c_name, value, exdays) {
    var exdate = new Date();
    exdate.setDate(exdate.getDate() + exdays);
    var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
    document.cookie = c_name + "=" + c_value;
}

function getCookie(c_name) {
    var i, x, y, ARRcookies = document.cookie.split(";");
    for (i = 0; i < ARRcookies.length; i++) {
        x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
        y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
        x = x.replace(/^\s+|\s+$/g, "");
        if (x == c_name) {
            return unescape(y);
        }
    }
}

function cssSelected() {
    var cssSelected = $('#myList')[0].value;
    if (cssSelected !== "select") {
        setCookie("selectedCSS", cssSelected, 3);
    }
}

$(document).ready(function() {
    $('#myList')[0].value = getCookie("selectedCSS");
})
</script>
<select id="myList" onchange="cssSelected();">
    <option value="select">--Select--</option>
    <option value="style-1.css">CSS1</option>
    <option value="style-2.css">CSS2</option>
    <option value="style-3.css">CSS3</option>
    <option value="style-4.css">CSS4</option>
</select>

This short and clean code:

::-webkit-input-placeholder {color: red;}
:-moz-placeholder           {color: red; /* For Firefox 18- */}
::-moz-placeholder          {color: red; /* For Firefox 19+ */}
:-ms-input-placeholder      {color: red;}

You can create these easily using the floating ability of CSS, for example. I have created a small example on Jsfiddle over here, all the related css and html is also provided there.

.foo {_x000D_
  float: left;_x000D_
  width: 20px;_x000D_
  height: 20px;_x000D_
  margin: 5px;_x000D_
  border: 1px solid rgba(0, 0, 0, .2);_x000D_
}_x000D_
_x000D_
.blue {_x000D_
  background: #13b4ff;_x000D_
}_x000D_
_x000D_
.purple {_x000D_
  background: #ab3fdd;_x000D_
}_x000D_
_x000D_
.wine {_x000D_
  background: #ae163e;_x000D_
}

<div class="foo blue"></div>_x000D_
<div class="foo purple"></div>_x000D_
<div class="foo wine"></div>

This code is working for blur effect for all browsers.

filter: blur(10px);
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);

PS: apart from the code, I also like the way the site shows it in action... really innovative.

Try the :host > /deep/ :

Add the following to the parent.component.less file

:host {
    /deep/ app-child-component {
       //your child style
    }
}

Replace the app-child-component by your child selector

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

Firstly, I highly recommend you do your CSS styling in an external CSS file, rather than doing it inline. It's much easier to maintain and can be more reusable using classes.

Working off Alex's answer (& Garret's clearfix) of "adding an element at the end with clear: both", you can do it like so:

    <div id='outerdiv' style='border: 1px solid black; background-color: black;'>
        <div style='width: 300px; border: red 1px dashed; float: left;'>
            <p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxx</p>
        </div>

        <div style='width: 300px; border: red 1px dashed; float: right;'>
            <p>zzzzzzzzzzzzzzzzzzzzzzzzzzzzz</p>
        </div>
        <div style='clear:both;'></div>
    </div>

This works (but as you can see inline CSS isn't so pretty).

Another way is with: overflow-y:hidden on the parent with padding.

#wrap {
    overflow-y: hidden;
    padding: 0 10px;
}
#wrap > div {
    width: 100px;
    height: 100px;
    box-shadow: 0 0 20px -5px red;
}

Sub-pixel rendering in browsers

Sub-pixel rendering is tricky. You can't actually expect a monitor to render a less than a pixel thin line. But it's possible to provide sub-pixel dimensions. Depending on the browser they render these differently. Check this John Resig's blog post about it.

Basically if your monitor is an LCD and you're drawing vertical lines, you can easily draw a 1/3 pixel line. If your background is white, give your line colour of #f0f. To the eye this line will be 1/3 of pixel wide. Although it will be of some colour, if you'd magnify monitor, you'd see that only one segment of the whole pixel (consisting of RGB) will be dark. This is pretty much technique that's used for fine type hinting i.e. ClearType.

But horizontal lines can only be a full pixel high. That's technology limitation of LCD monitors. CRTs were even more complicated with their triangular phosphors (unless they were aperture grille type ie. Sony Trinitron) but that's a different story.

Basically providing a sub-pixel dimension and expecting it to render that way is same as expecting an integer variable to store a number of 1.2034759349. If you understand this is impossible, you should understand that monitors aren't able to render sub-pixel dimensions.

Cross browser safe style

But the way horizontal rules that blend in are usually done using colours. So if your background is for instance white (#fff) you can always make your HR very light. Like #eee.

The cross browser safe style for very light horizontal rule would be:

hr
{
    background-color: #eee;
    border: 0 none;
    color: #eee;
    height: 1px;
}

And use a CSS file instead of in-line styles. They provide a central definition for the whole site not just a particular element. It makes maintainability much better.

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

You could also use a CSS "calc" to get the same effect instead of using the negative margin or transform properties (in case you want to use those properties for anything else).

.hero:after,
.hero:after {
    z-index: -1;
    position: absolute;
    top: 98.1%;
    left: calc(50% - 25px);
    content: '';
    width: 0;
    height: 0;
    border-top: solid 50px #e15915;
    border-left: solid 50px transparent;
    border-right: solid 50px transparent;
}

You can also affect differente DOM elements using :target pseudo class. If an element is the destination of an anchor target it will get the :target pseudo element.

<style>
p { color:black; }
p:target { color:red; }
</style>

<a href="#elem">Click me</a>
<p id="elem">And I will change</p>

Here is a fiddle : https://jsfiddle.net/k86b81jv/

CSS has different pseudo selector by which you can achieve such effect. In your case you can use

:active : if you want background color only when the button is clicked and don't want to persist.

:focus: if you want background color untill the focus is on the button.

button:active{
    background:olive;
}

and

button:focus{
    background:olive;
}

P.S.: Please don't give the number in Id attribute of html elements.

In stead of link-tag in html-head to external css file, use php-include:

<style>
<?php
include("style.css");
?>      
</style>

Kind of hack, but works for me :)

For everyone having the same issue, make sure you actually wrote "120px" instead of only "120". This was my mistake and it drove me crazy.

Add this before calling dialog

$( obiect ).css('zIndex',9999);

And remove

 zIndex: 700,

from dialog

The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr) instead of 1fr as your track size.

There are two ways to do this:

CSS: Use width as %, like 75%, so the width of the div will change automatically when user resizes the browser.

Javascipt: Use resize event

$(window).bind('resize', function()
{
    if($(window).width() > 500)
        $('#divID').css('width', '300px');
    else
        $('divID').css('width', '200px');
});

Hope this will help you :)

You could create a canvas (via javascript) and draw a dotted line within. Within the canvas you can control how long the dash and the space in between shall be.

There is an issue with iOS not registering click/touch events bound to elements added after DOM loads.

While PPK has this advice: http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

I've found this the easy fix, simply add this to the css:

cursor: pointer;

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

HTML

<div class="container-fluid h-100 bg-light text-dark">
  <div class="row justify-content-center align-items-center">
    <h1>Form</h1>    
  </div>
  <hr/>
  <div class="row justify-content-center align-items-center h-100">
    <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">
      <form action="">
        <div class="form-group">
          <select class="form-control">
                    <option>Option 1</option>
                    <option>Option 2</option>
                  </select>
        </div>
        <div class="form-group">
          <input type="text" class="form-control" />
        </div>
        <div class="form-group text-center">
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio">Option 1
  </label>
          </div>
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio">Option 2
  </label>
          </div>
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio" disabled>Option 3
  </label>
          </div>
        </div>
        <div class="form-group">
          <div class="container">
            <div class="row">
              <div class="col"><button class="col-6 btn btn-secondary btn-sm float-left">Reset</button></div>
              <div class="col"><button class="col-6 btn btn-primary btn-sm float-right">Submit</button></div>
            </div>
          </div>
        </div>

      </form>
    </div>
  </div>
</div>

I hope this helps someone. Thank you.

quite simple:

ul.yourlist li { float:left; }

or

ul.yourlist li { display:inline; }

Use <div class="row"> and <div class="form-group col-xs-6">

Here a fiddle :https://jsfiddle.net/core972/SMkZV/2/

You need to define height of ul or your div and set overflow equals to auto as below:

<ul style="width: 300px; height: 200px; overflow: auto">
  <li>text</li>
  <li>text</li>

It's the maximum value of a 32 bits integer: 2147483647

Also see the docs: https://www.w3.org/TR/CSS22/visuren.html#z-index (Negative numbers are allowed)

Try putting opacity:0; your select element will be invisible but the options will be visible when you click on it.

There are four cases.

1. By default, active and focus are both off.
2. When you tab to cycle through focusable elements, they will enter :focus (without active).
3. When you click on a non-focusable element, it enters :active (without focus).
4. When you click on a focusable element it enters :active:focus (active and focus simultaneously).

Example:

<div>
  I cannot be focused.
</div>

<div tabindex="0">
  I am focusable.
</div>

div:focus {
  background: green;
}

div:active {
  color: orange;
}

div:focus:active {
  font-weight: bold;
}

When the page loads both are in case 1. When you press tab you will focus the second div and see it exhibit case 2. When you click on the first div you see case 3. When you click the second div, you see case 4.

Whether an element is focusable or not is another question. Most are not by default. But, it's safe to assume <a>, <input>, <textarea> are focusable by default.

I usually use the overflow: auto trick; although that's not, strictly speaking, the intended use for overflow, it is kinda related - enough to make it easy to remember, certainly. The meaning of float: left itself has been extended for various uses more significantly than overflow is in this example, IMO.

Here's one more alternative:

var classElements = document.getElementsByClassName("className");

function setClassHeight (classElements, desiredHeightValue) 
    {
        var arrayElements = Object.entries(classElements);
        for(var i = 0; i< arrayElements.length; i++) {
            arrayElements[i][1].style.height = desiredHeightValue;
        }

    }

This solution worked great for me :

@media (max-width: 767px) {
    .table-responsive .dropdown-menu {
        position: static !important;
    }
}
@media (min-width: 768px) {
    .table-responsive {
        overflow: visible;
    }
}

Add some css either in the head or in a external document. asp:TextBox are rendered as input :

input {
     width:100%;
}

Your html should look like : http://jsfiddle.net/c5WXA/

Note this will affect all your textbox : if you don't want this, give the containing div a class and specify the css.

.divClass input {
     width:100%;
}

Have you tried overflow-y:auto ? It is not exactly what you want, as the scrollbar will appear only when needed.

use rgba (rgb with alpha transparency):

border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity

The alpha transparency variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)

See http://jsfiddle.net/SWcCt/.

Just set a line-height the half of height:

line-height:20px;
height:40px;

Of course, in order to make text-overflow: ellipsis work you also need:

overflow:hidden;
white-space: pre;

Supposing you have the following file structure:

-css
  --index.css
-images
  --image1.png
  --image2.png
  --image3.png

In CSS you can access image1, for example, using the line ../images/image1.png.

NOTE: If you are using Chrome, it may doesn't work and you will get an error that the file could not be found. I had the same problem, so I just deleted the entire cache history from chrome and it worked.

Similar to hooblei's answer, just with interpolation:

<li ng-style="{'background-image': 'url({{ image.source }})'}">...</li>

Try RGBA, e.g.

div { background-color: rgba(255, 255, 255, 0.5); }

As always, this won't work in every single browser ever written.

Using inline styling use <a href="your link here" style="cursor:default">your content here</a>. See this example

Alternatively use css. See this example.

This solution is cross-browser compatible.

In some cases (blocks without any content, but with background) it can be overridden using borders, individually for every block.

For example:

.colored {
  background: #000;
  border: 1px solid #ccc;
  width: 8px;
  height: 8px;
}

@media print {
  .colored div {
    border: 4px solid #000;
    width: 0;
    height: 0;
  }
}

To use "include" to include CSS, you have to tell PHP you're using CSS code. Add this to your header of your CSS file and make it main.php (or styles.css, or whatever):

header("Content-type: text/css; charset: UTF-8");

This might help with some user's connections, but it theoretically (read: I haven't tested it) adds processor overhead to your server and according to Steve Souder, because your computer can download multiple files at once, using include could be slower. If you have your CSS split into a dozen files, maybe it would be faster?

Steve's blog post: http://www.stevesouders.com/blog/2009/04/09/dont-use-import/ Source: http://css-tricks.com/css-variables-with-php/

None of the solutions worked for me. If everything else fails, get the picture to Photoshop and apply some effect. 5 minutes versus so much time on this...

It's not open source, but you can at least get a free personal use license to Prince, which really does a lovely job.

Use CSS attribute selectors:

https://developer.mozilla.org/en-US/docs/CSS/Attribute_selectors

e.g.:

div[role=main]

The following works for me in Internet Explorer. Note the addition of the table-layout:fixed CSS attribute

td {_x000D_
  border: 1px solid;_x000D_
}

<table style="table-layout: fixed; width: 100%">_x000D_
  <tr>_x000D_
    <td style="word-wrap: break-word">_x000D_
      LongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongWord_x000D_
    </td>_x000D_
  </tr>_x000D_
</table>

In case your html has the (rough) structure:

<div class="wrapper">
   <div>....</div>
   ...
   <div>....</div>
</div>
<div class="footer">
   ...
</div>

then the simplest css that fixes footer to the bottom of your screen is

html, body {
    height: 100%;
}
.wrapper {
  min-height: calc(100vh - 80px);
}
.footer {
   height: 80px;
}

... where the height of the footer is 80px. calc calculates the height of the wrapper to be equal to the window's height minus the height of the footer (80px) which is out of the .wrapper

fareed namrouti answer is correct. But the background still get yellow when the input is selected. Adding !important fix the problem. If you want also textarea and select with the same behavior just add textarea:-webkit-autofill, select:-webkit-autofill

Only input

input:-webkit-autofill {
    background-color: rgb(250, 255, 189) !important;
}

input, select, textarea

input:-webkit-autofill, textarea:-webkit-autofill, select:-webkit-autofill {
    background-color: rgb(250, 255, 189) !important;
}

You can't set a favicon from CSS - if you want to do this explicitly you have to do it in the markup as you described.

Most browsers will, however, look for a favicon.ico file on the root of the web site - so if you access http://example.com most browsers will look for http://example.com/favicon.ico automatically.

Use the background-color property instead of the background property in your CSS. So your code will look like this:
.fb-icon:hover {
background: blue;
}

use css overflow:scroll; property. you need to specify height and width then you will be able to scroll horizontally and vertically or either one of two scroll by setting overflow-x:auto; or overflow-y:auto;

Here this should help you

The below jsfiddle link will help you understand how to rotate a image.I used the same one to rotate the dial of a clock.

http://jsfiddle.net/xw89p/

var rotation = function (){
   $("#image").rotate({
      angle:0, 
      animateTo:360, 
      callback: rotation,
      easing: function (x,t,b,c,d){       
          return c*(t/d)+b;
      }
   });
}
rotation();

Where: • t: current time,

• b: begInnIng value,

• c: change In value,

• d: duration,

• x: unused

No easing (linear easing): function(x, t, b, c, d) { return b+(t/d)*c ; }

Building on the answer from @fzzle - to achieve a circle from a rectangle without defining a fixed height or width, the following will work. The padding-top:100% keeps a 1:1 ratio for the circle-cropper div. Set an inline background image, center it, and use background-size:cover to hide any excess.

CSS

.circle-cropper {
  background-repeat: no-repeat;
  background-size: cover;
  background-position: 50%;
  border-radius: 50%;
  width: 100%;
  padding-top: 100%;
}

HTML

<div class="circle-cropper" role="img" style="background-image:url(myrectangle.jpg);"></div>

Just put it between center tags:

<center>><Your text here>></center>

Assuming that your markup looks like:

<div id="header" style="position: fixed;"></div>
<div id="content" style="position: relative;"></div>

Now both elements are positioned; in which case, the element at the bottom (in source order) will cover element above it (in source order).

Add a z-index on header; 1 should be sufficient.

WOFF 2.0, based on the Brotli compression algorithm and other improvements over WOFF 1.0 giving more than 30 % reduction in file size, is supported in Chrome, Opera, and Firefox.

http://en.wikipedia.org/wiki/Web_Open_Font_Format http://en.wikipedia.org/wiki/Brotli

http://sth.name/2014/09/03/Speed-up-webfonts/ has an example on how to use it.

Basically you add a src url to the woff2 file and specify the woff2 format. It is important to have this before the woff-format: the browser will use the first format that it supports.

have you tried using <pre> tag.

http://jsfiddle.net/NweRa/

This works, but all the children of the element with this class will also become transparent, without any way of preventing that.

.css-class-name {
    opacity:0.8;
}

Use style. The font tag is deprecated (W3C Wiki).

I am new to Angular but have found this to solve my issue:

<i class="icon-download" ng-click="showDetails = ! showDetails" ng-class="{'icon-upload': showDetails}"></i>

This will conditionally apply a class based on a var. It starts off with a icon-download as a default, the using ng-class, I check the status of showDetails if true/false and apply class icon-upload. Its working great.

Hope it helps.

No this is not possible, SVG elements do not have background-... presentation attributes.

To simulate this effect you could draw a rectangle behind the text attribute with fill="green" or something similar (filters). Using JavaScript you could do the following:

var ctx = document.getElementById("the-svg"),
textElm = ctx.getElementById("the-text"),
SVGRect = textElm.getBBox();

var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect");
    rect.setAttribute("x", SVGRect.x);
    rect.setAttribute("y", SVGRect.y);
    rect.setAttribute("width", SVGRect.width);
    rect.setAttribute("height", SVGRect.height);
    rect.setAttribute("fill", "yellow");
    ctx.insertBefore(rect, textElm);

I originally asked this question I was looking for a Chrome (or FireFox) solution, but I stumbled across this feature in Internet Explorer developer tools. Pretty much what I'm looking for (except for the javascript)

Result:

Sometimes you can play with padding and margin top, add line-height, etc.

See fiddle.

Style and text forked from @aspirinemaga

.parent
{
    width:300px;
    line-height:30px;
    border:1px solid red;
    padding-top:20px;
}

You need to push the container down the navbar.

Please find my working fiddle here http://jsfiddle.net/meetravi/aXCMW/1/

<header>

    <h2 class="title">Test</h2>
</header>
<div class="navbar">
    <div class="navbar-inner">
        <ul class="nav">
            <li class="active"><a href="#">Test1</a></li>
            <li><a href="#">Test2</a></li>
            <li><a href="#">Test3</a></li>
            <li><a href="#">Test4</a></li>
            <li><a href="#">Test5</a></li>

        </ul>
    </div>
</div>
<div class="container">

</div>

Just hit on this when trying to solve this type of thing my self.

I did a selector that deals with the element after being something other than a p.

.here .is.the #selector h4 + * {...}

Hope this helps anyone who finds it :)

You need also to set .min-height: 0px; please see bellow:

.navbar-inner {
    min-height: 0px;
}

.navbar-brand,
.navbar-nav li a {
    line-height: 150px;
    height: 150px;
    padding-top: 0;
}

If you set .min-height: 0px; then you can choose any height you want!

Good Luck!

This is a common concern.

The default outline that browsers render is ugly.

See this for example:

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}

<form>_x000D_
  <label>Click to see the input below to see the outline</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

The most common "fix" that most recommend is outline:none - which if used incorrectly - is disaster for accessibility.

So...of what use is the outline anyway?

There's a very dry-cut website I found which explains everything well.

It provides visual feedback for links that have "focus" when navigating a web document using the TAB key (or equivalent). This is especially useful for folks who can't use a mouse or have a visual impairment. If you remove the outline you are making your site inaccessible for these people.

Ok, let's try it out same example as above, now use the TAB key to navigate.

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}

<form>_x000D_
  <label>Click on this text and then use the TAB key to naviagte inside the snippet.</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

Notice how you can tell where the focus is even without clicking the input?

Now, let's try outline:none on our trusty <input>

So, once again, use the TAB key to navigate after clicking the text and see what happens.

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none;_x000D_
}

<form>_x000D_
  <label>Click on this text and then use the TAB key to naviagte inside the snippet.</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

See how it's more difficult to figure out where the focus is? The only telling sign is the cursor blinking. My example above is overly simplistic. In real-world situations, you wouldn't have only one element on the page. Something more along the lines of this.

.wrapper {_x000D_
  width: 500px;_x000D_
  max-width: 100%;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
_x000D_
form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none;_x000D_
}

<div class="wrapper">_x000D_
_x000D_
  <form>_x000D_
    <label>Click on this text and then use the TAB key to naviagte inside the snippet.</label>_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_
  </form>_x000D_
_x000D_
  <form>_x000D_
    First name:<br>_x000D_
    <input type="text" name="firstname"><br> Last name:<br>_x000D_

    </fieldset>_x000D_
  </form>_x000D_
_x000D_
</div>

Now compare that to the same template if we keep the outline:

.wrapper {_x000D_
  width: 500px;_x000D_
  max-width: 100%;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
_x000D_

_x000D_

}

<div class="wrapper">_x000D_

  </form>_x000D_
_x000D_

_x000D_
  <form>_x000D_
    <label for="GET-name">Name:</label>_x000D_
    <input id="GET-name" type="text" name="name">_x000D_

  </form>_x000D_
_x000D_
</div>

So we have established the following

1. Outlines are ugly
2. Removing them makes life more difficult.

So what's the answer?

Remove the ugly outline and add your own visual cues to indicate focus.

Here's a very simple example of what I mean.

I remove the outline and add a bottom border on :focus and :active. I also remove the default borders on the top, left and right sides by setting them to transparent on :focus and :active (personal preference)

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none_x000D_
}_x000D_
_x000D_
input:focus,_x000D_
input:active {_x000D_
  border-color: transparent;_x000D_
  border-bottom: 2px solid red_x000D_
}

<form>_x000D_
  <label>Click to see the input below to see the outline</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

So, we try the approach above with our "real-world" example from earlier:

.wrapper {_x000D_
  width: 500px;_x000D_
  max-width: 100%;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
_x000D_
form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none_x000D_
}_x000D_
_x000D_
input:focus,_x000D_
input:active {_x000D_
  border-color: transparent;_x000D_
  border-bottom: 2px solid red_x000D_
}

<div class="wrapper">_x000D_

    <input id="GET-name" type="text" name="name">_x000D_

_x000D_
_x000D_
  <form>_x000D_
    <label for="POST-name">Name:</label>_x000D_
    <input id="POST-name" type="text" name="name">_x000D_

_x000D_
_x000D_
  <form>_x000D_
    <fieldset>_x000D_
      <legend>Title</legend>_x000D_
      <input type="radio" name="radio" id="radio">_x000D_
      <label for="radio">Click me</label>_x000D_
    </fieldset>_x000D_
  </form>_x000D_
_x000D_
</div>

This can be extended further by using external libraries that build on the idea of modifying the "outline" as opposed to removing it entirely like Materialize

You can end up with something that is not ugly and works with very little effort

Yes you can! Just tested this and it works great, this is awesome! It still doesn't work with html, but it does with svg.

In my index.html I have:

<div id="test" style="content: url(test.svg); width: 200px; height: 200px;"></div>

And my test.svg looks like this:

<svg xmlns="http://www.w3.org/2000/svg">
   <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/>
   <polyline points="20,20 40,25 60,40 80,120 120,140 200,180" style="fill:none;stroke:black;stroke-width:3"/>
</svg> 

I originally found a CSS way to bypass this when using the Cycle jQuery plugin. Cycle uses JavaScript to set my slide to overflow: hidden, so when setting my pictures to width: 100% the pictures would look vertically cut, and so I forced them to be visible with !important and to avoid showing the slide animation out of the box I set overflow: hidden to the container div of the slide. Hope it works for you.

UPDATE - New Solution:

Original problem -> http://jsfiddle.net/xMddf/1/ (Even if I use overflow-y: visible it becomes "auto" and actually "scroll".)

#content {
    height: 100px;
    width: 200px;
    overflow-x: hidden;
    overflow-y: visible;
}

The new solution -> http://jsfiddle.net/xMddf/2/ (I found a workaround using a wrapper div to apply overflow-x and overflow-y to different DOM elements as James Khoury advised on the problem of combining visible and hidden to a single DOM element.)

#wrapper {
    height: 100px;
    overflow-y: visible;
}
#content {
    width: 200px;
    overflow-x: hidden;
}

Use this code to generate horizontal scrolling blocks contents. I got this from here http://www.htmlexplorer.com/2014/02/horizontal-scrolling-webpage-content.html

}

Old topic, but I was recently affected by this.

Using a class "row-fluid" instead of "row" worked fine for me but I'm not sure if it's fully supported going forward.

So after reading Why does the bootstrap .row has a default margin-left of -30px I just used the <div> (without any row class) and it behaved exactly like <div class="row-fluid">

The only way would probably be to set different widths for different screen sizes, but this approach is pretty inacurate and you should use a js solution.

h1 {
    font-size: 20px;
}

@media all and (max-device-width: 720px){
    h1 {
        font-size: 18px;
    }
}

@media all and (max-device-width: 640px){
    h1 {
        font-size: 16px;
    }
}

@media all and (max-device-width: 320px){
    h1 {
        font-size: 12px;
    }
}

The simplest way to get equal height columns, without the ugly side effects that come along with absolute positioning, is to use the display: table properties:

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: table;
}

.div2, .div3 {
  display: table-cell;
}
.div2 {
  width:150px;
  height:auto;
  background-color: #F4A460;  

}
.div3 {
  width:150px;
  height:auto;
  background-color: #FFFFE0;  
}

http://jsfiddle.net/E4Zgj/21/

Now, if your goal is to have .div2 so that it is only as tall as it needs to be to contain its content while .div3 is at least as tall as .div2 but still able to expand if its content makes it taller than .div2, then you need to use flexbox. Flexbox support isn't quite there yet (IE10, Opera, Chrome. Firefox follows an old spec, but is following the current spec soon).

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: flex;
  align-items: flex-start;
}

.div2 {
  width:150px;
  background-color: #F4A460;
}

.div3 {
  width:150px;
  background-color: #FFFFE0;
  align-self: stretch;
}

http://jsfiddle.net/E4Zgj/22/

There's actually a pretty easy way to do this. The code should be something like:

<script type="test/javascript">

    function showcontent(x){

      if(window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
      } else {
        xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
      }

      xmlhttp.onreadystatechange = function() {
        if(xmlhttp.readyState == 1) {
            document.getElementById('content').innerHTML = "<img src='loading.gif' />";
        }
        if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
          document.getElementById('content').innerHTML = xmlhttp.responseText;
        } 
      }

      xmlhttp.open('POST', x+'.html', true);
      xmlhttp.setRequestHeader('Content-type','application/x-www-form-urlencoded');
      xmlhttp.send(null);

    }

And in the HTML:

<body onload="showcontent(main)"> <!-- onload optional -->
<div id="content"><img src="loading.gif"></div> <!-- leave img out if not onload -->
</body>

I did something like that on my page and it works great.

How can i do something like that but without using absolute position and float?

Apart from using the inline-block approach (as mentioned in other answers) here are some other approaches:

1) CSS tables (FIDDLE)

.container {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
}_x000D_
.container div {_x000D_
  display: table-cell;_x000D_
}

<div class="container">_x000D_
  <div>A</div>_x000D_
  <div>B</div>_x000D_
</div>

2) Flexbox (FIDDLE)

.container {_x000D_
  display: flex;_x000D_
}_x000D_
.container div {_x000D_
  flex: 1;_x000D_
}

<div class="container">_x000D_
  <div>A</div>_x000D_
  <div>B</div>_x000D_
</div>

For a reference, this CSS-tricks post seems to sum up the various approaches to acheive this.

Instead of using a %, the units vh set it to a percent of the viewport (browser window) size.

I was able to set a modal with an image and text beneath to be responsive to the browser window size using vh.

If you just want the content to scroll, you could leave out the part that limits the size of the modal body.

/*When the modal fills the screen it has an even 2.5% on top and bottom*/
/*Centers the modal*/
.modal-dialog {
  margin: 2.5vh auto;
}

/*Sets the maximum height of the entire modal to 95% of the screen height*/
.modal-content {
  max-height: 95vh;
  overflow: scroll;
}

/*Sets the maximum height of the modal body to 90% of the screen height*/
.modal-body {
  max-height: 90vh;
}
/*Sets the maximum height of the modal image to 69% of the screen height*/
.modal-body img {
  max-height: 69vh;
}

use the spread value...

box-shadow has the following values

box-shadow: x y blur spread color;

so you could use something like..

box-shadow: 0px -10px 10px -10px black;

UPDATE: i'm adding a jsfiddle

I liked @KyleMit's answer on how to make an unstyled input group, but in my case, I only wanted the right side unstyled - I still wanted to use an input-group-addon on the left side and have it look like normal bootstrap. So, I did this:

css

.input-group.input-group-unstyled-right input.form-control {
    border-top-right-radius: 4px;
    border-bottom-right-radius: 4px;
}
.input-group-unstyled-right .input-group-addon.input-group-addon-unstyled {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

html

<div class="input-group input-group-unstyled-right">
    <span class="input-group-addon">
        <i class="fa fa-envelope-o"></i>
    </span>
    <input type="text" class="form-control">
    <span class="input-group-addon input-group-addon-unstyled">
        <i class="fa fa-check"></i>
    </span>
</div>

you can use simply inside your controller: return response()->download($filePath); Happy coding :)

I forgot to annotate my component with "@Input" (Doh!)

book-list.component.html (Offending code):

<app-book-item
  *ngFor="let book of book$ | async"
  [book]="book">  <-- Can't bind to 'book' since it isn't a known property of 'app-book-item'
</app-book-item>

Corrected version of book-item.component.ts:

import { Component, OnInit, Input } from '@angular/core';

import { Book } from '../model/book';
import { BookService } from '../services/book.service';

@Component({
  selector: 'app-book-item',
  templateUrl: './book-item.component.html',
  styleUrls: ['./book-item.component.css']
})
export class BookItemComponent implements OnInit {

  @Input()
  public book: Book;

  constructor(private bookService: BookService)  { }

  ngOnInit() {}

}

I made a collection layout.

To make the separator visible, Set the background color of the collection view to gray. One row per section.

Useage:

let layout = GridCollectionViewLayout()
layout.cellHeight = 50 // if not set, cellHeight = Collection.height/numberOfSections
layout.cellWidth = 50  // if not set, cellWidth = Collection.width/numberOfItems(inSection)
collectionView.collectionViewLayout = layout

Layout:

import UIKit

class GridCollectionViewLayout: UICollectionViewLayout {


var cellWidth : CGFloat = 0
var cellHeight : CGFloat = 0
var seperator: CGFloat = 1

private var cache = [UICollectionViewLayoutAttributes]()



override func prepare() {

    guard let collectionView = self.collectionView else {
        return
    }

    self.cache.removeAll()



        let numberOfSections = collectionView.numberOfSections

        if cellHeight <= 0
        {
            cellHeight = (collectionView.bounds.height - seperator*CGFloat(numberOfSections-1))/CGFloat(numberOfSections)
        }

        for section in 0..<collectionView.numberOfSections {

            let numberOfItems = collectionView.numberOfItems(inSection: section)

            let cellWidth2 : CGFloat
            if cellWidth <= 0
            {
                cellWidth2 = (collectionView.bounds.width - seperator*CGFloat(numberOfItems-1))/CGFloat(numberOfItems)
            }
            else
            {
                cellWidth2 = cellWidth
            }


            for row in 0..<numberOfItems {


                let indexPath = NSIndexPath(row: row, section: section)

                let attributes = UICollectionViewLayoutAttributes(forCellWith: indexPath as IndexPath)
                attributes.frame = CGRect(x: (cellWidth2+seperator)*CGFloat(row),
                                          y: (cellHeight+seperator)*CGFloat(section),
                                          width: cellWidth2,
                                          height: cellHeight)

                //row_temp.append(attributes)

                self.cache.append(attributes)
            }
            //self.itemAttributes.append(row_temp)

DEMO ?

None of these solutions quite worked for me. My original audio was being overwritten, or I was getting an error like "failed to map memory" with the more complex 'amerge' example. It seems I needed -filter_complex amix.

ffmpeg -i videowithaudioyouwanttokeep.mp4 -i audiotooverlay.mp3 -vcodec copy -filter_complex amix -map 0:v -map 0:a -map 1:a -shortest -b:a 144k out.mkv

I ended up solving my own problem.

Apparently in iOS 8 SDK, requestAlwaysAuthorization (for background location) or requestWhenInUseAuthorization (location only when foreground) call on CLLocationManager is needed before starting location updates.

There also needs to be NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key in Info.plist with a message to be displayed in the prompt. Adding these solved my problem.

For more extensive information, have a look at: Core-Location-Manager-Changes-in-ios-8

\r can do the work here for you.

    <div ng-if="modeldate==''"><span ng-message="required" class="change">Date is required</span> </div>

you can use the ng-if directive as above.

If you want to see a more detailed discussion of differences for the commands, see the Details about Differences section, below.

From the LeMoDa.net website¹ (archived), specifically the Windows and Unix command line equivalents page (archived), I found the following². There's a better/more complete table in the next edit.

Windows command     Unix command
rmdir               rmdir
rmdir /s            rm -r
move                mv

I'm interested to hear from @Dave and @javadba to hear how equivalent the commands are - how the "behavior and capabilities" compare, whether quite similar or "woefully NOT equivalent".

All I found out was that when I used it to try and recursively remove a directory and its constituent files and subdirectories, e.g.

(Windows cmd)>rmdir /s C:\my\dirwithsubdirs\

gave me a standard Windows-knows-better-than-you-do-are-you-sure message and prompt

dirwithsubdirs, Are you sure (Y/N)?

and that when I typed Y, the result was that my top directory and its constituent files and subdirectories went away.

Edit

I'm looking back at this after finding this answer. I retried each of the commands, and I'd change the table a little bit.

Windows command     Unix command
rmdir               rmdir
rmdir /s /q         rm -r
rmdir /s /q         rm -rf
rmdir /s            rm -ri
move                mv
del <file>          rm <file>

If you want the equivalent for

rm -rf

you can use

rmdir /s /q

or, as the author of the answer I sourced described,

But there is another "old school" way to do it that was used back in the day when commands did not have options to suppress confirmation messages. Simply ECHO the needed response and pipe the value into the command.

echo y | rmdir /s

Details about Differences

I tested each of the commands using Windows CMD and Cygwin (with its bash).

Before each test, I made the following setup.

Windows CMD

>mkdir this_directory
>echo some text stuff > this_directory/some.txt
>mkdir this_empty_directory

Cygwin bash

$ mkdir this_directory
$ echo "some text stuff" > this_directory/some.txt
$ mkdir this_empty_directory

That resulted in the following file structure for both.

base
|-- this_directory
|   `-- some.txt
`-- this_empty_directory

Here are the results. Note that I'll not mark each as CMD or bash; the CMD will have a > in front, and the bash will have a $ in front.

RMDIR

>rmdir this_directory
The directory is not empty.

>tree /a /f .
Folder PATH listing for volume Windows
Volume serial number is ¦¦¦¦¦¦¦¦ ¦¦¦¦:¦¦¦¦
base
+---this_directory
|       some.txt
|
\---this_empty_directory

> rmdir this_empty_directory

>tree /a /f .
base
\---this_directory
        some.txt

$ rmdir this_directory
rmdir: failed to remove 'this_directory': Directory not empty

$ tree --charset=ascii
base

2 directories, 1 file

$ rmdir this_empty_directory

$ tree --charset=ascii

`-- this_directory
    `-- some.txt

RMDIR /S /Q and RM -R ; RM -RF

>rmdir /s /q this_directory

>tree /a /f
base
\---this_empty_directory

>rmdir /s /q this_empty_directory

>tree /a /f
base
No subfolders exist

$ rm -r this_directory

$ tree --charset=ascii
base

$ rm -r this_empty_directory

$ tree --charset=ascii
base

$ rm -rf this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -rf this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

RMDIR /S AND RM -RI Here, we have a bit of a difference, but they're pretty close.

>rmdir /s this_directory
this_directory, Are you sure (Y/N)? y

>tree /a /f
base
\---this_empty_directory

>rmdir /s this_empty_directory
this_empty_directory, Are you sure (Y/N)? y

>tree /a /f
base
No subfolders exist

$ rm -ri this_directory
rm: descend into directory 'this_directory'? y
rm: remove regular file 'this_directory/some.txt'? y
rm: remove directory 'this_directory'? y

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -ri this_empty_directory
rm: remove directory 'this_empty_directory'? y

$ tree --charset=ascii
base
0 directories, 0 files

I'M HOPING TO GET A MORE THOROUGH MOVE AND MV TEST

Notes

1. I know almost nothing about the LeMoDa website, other than the fact that the info is

and that there seem to be a bunch of useful programming tips along with some humour (yes, the British spelling) and information on how to fix Japanese toilets. I also found some stuff talking about the "Ibaraki Report", but I don't know if that is the website.

I think I shall go there more often; it's quite useful. Props to Ben Bullock, whose email is on his page. If he wants me to remove this info, I will.

2. Actually, I found the information with a Google search for "cmd equivalent of rm"

https://www.google.com/search?q=cmd+equivalent+of+rm

The information I'm sharing came up first.

I solved this problem by this solution.

you just change in this file /etc/yum.repos.d/epel.repo

mirrorlist= change this url https to http

baseurl= change this url https to http

Use the -e argument and the escape character \n:

echo -e "This will generate a next line \nThis new line is the result"

You can use the basename() function.

In Angular 1.3 I would do this:

HTML:

<input ng-model="msg" ng-model-options="{debounce: 1000}">

Controller:

$scope.$watch('variableName', function(nVal, oVal) {
    if (nVal !== oVal) {
        myDebouncedFunction();
    }
});

Basically you're telling angular to run myDebouncedFunction(), when the the msg scope variable changes. The attribute ng-model-options="{debounce: 1000}" makes sure that msg can only update once a second.

For the beginners:

Null coalescing operator (??)

Everything is true except null values and undefined (variable/array index/object attributes)

ex:

$array = [];
$object = new stdClass();

var_export (false ?? 'second');                           # false
var_export (true  ?? 'second');                           # true
var_export (null  ?? 'second');                           # 'second'
var_export (''    ?? 'second');                           # ""
var_export ('some text'    ?? 'second');                  # "some text"
var_export (0     ?? 'second');                           # 0
var_export ($undefinedVarible ?? 'second');               # "second"
var_export ($array['undefined_index'] ?? 'second');       # "second"
var_export ($object->undefinedAttribute ?? 'second');     # "second"

this is basically check the variable(array index, object attribute.. etc) is exist and not null. similar to isset function

Ternary operator shorthand (?:)

every false things (false,null,0,empty string) are come as false, but if it's a undefined it also come as false but Notice will throw

ex

$array = [];
$object = new stdClass();

var_export (false ?: 'second');                           # "second"
var_export (true  ?: 'second');                           # true
var_export (null  ?: 'second');                           # "second"
var_export (''    ?: 'second');                           # "second"
var_export ('some text'    ?? 'second');                  # "some text"
var_export (0     ?: 'second');                           # "second"
var_export ($undefinedVarible ?: 'second');               # "second" Notice: Undefined variable: ..
var_export ($array['undefined_index'] ?: 'second');       # "second" Notice: Undefined index: ..
var_export ($object->undefinedAttribute ?: 'second');     # "Notice: Undefined index: ..

Hope this helps

I suggest using a DataTable.DefaultView as a DataSource. Then the line below.

foreach (DataGridViewColumn column in gridview.Columns)
    {
       column.SortMode = DataGridViewColumnSortMode.Automatic;
    }

After that the gridview itself will manage sorting(Ascending or Descending is supported.)

Make sure the test class is in a sub-package of your main spring boot class

I do it for beamer presentations,

provide tmp-0.png through tmp-34.png

\end{frame}

The CSS code below works to remove this:

a:focus, a:active, 
button::-moz-focus-inner,
input[type="reset"]::-moz-focus-inner,
input[type="button"]::-moz-focus-inner,
input[type="submit"]::-moz-focus-inner,
select::-moz-focus-inner,
input[type="file"] > input[type="button"]::-moz-focus-inner {
    border: 0;
    outline : 0;
}

Edit your app at www.facebook.com/developers/ and set the "Site URL" to "http://localhost/myapppath".

When done - change it back.

Here's a simple way to accomplish this with jQuery that limits it to the appropriate input elements:

//prevent submission of forms when pressing Enter key in a text input
$(document).on('keypress', ':input:not(textarea):not([type=submit])', function (e) {
    if (e.which == 13) e.preventDefault();
});

Thanks to this answer: https://stackoverflow.com/a/1977126/560114.

Okay, let's understand the difference between active and passive code.

The active code is the implementation of functions, procedures, methods, i.e. the pieces of code that should be compiled to executable machine code. We store it in .c files and sure we need to compile it.

The passive code is not being execute itself, but it needed to explain the different modules how to communicate with each other. Usually, .h files contains only prototypes (function headers), structures.

An exception are macros, that formally can contain an active pieces, but you should understand that they are using at the very early stage of building (preprocessing) with simple substitution. At the compile time macros already are substituted to your .c file.

Another exception are C++ templates, that should be implemented in .h files. But here is the story similar to macros: they are substituted on the early stage (instantiation) and formally, each other instantiation is another type.

In conclusion, I think, if the modules formed properly, we should never compile the header files.

In my case it was a simple bug in the code, using a variable before it was created. Worth checking that out before trying the above solutions. Why I got this particular error message, Lord knows.

The Java volatile modifier is an example of a special mechanism to guarantee that communication happens between threads. When one thread writes to a volatile variable, and another thread sees that write, the first thread is telling the second about all of the contents of memory up until it performed the write to that volatile variable.

Atomic operations are performed in a single unit of task without interference from other operations. Atomic operations are necessity in multi-threaded environment to avoid data inconsistency.

You also encounter this if you run an Application on a Scheduled Task in Non-Interactive mode.

As soon as you show a Dialog it throws the error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

You can see its a MessageBox causing the problem in the stack trace:

at System.Windows.Forms.MessageBox.ShowCore(IWin32Window owner, String text, String caption, MessageBoxButtons buttons, MessageBoxIcon icon,  MessageBoxDefaultButton defaultButton, MessageBoxOptions options, Boolean showHelp)  

Solution

If you're running your app on a Scheduled Task send an email instead of showing a Dialog.

Both std::string and std::vector<T> have constructors initializing the object to be empty. You could use std::vector<unsigned char>() but I'd remove the initializer.

I resolved this problem by checking my file system the disk was completely full, and so database could not start up

connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432" ?

I tried series of troubleshooting, until when i checked my disk usage and found that it was full, 100% usage,

df -h
cd /var/log/odoo/
cat /dev/null > odoo-server.log
reboot

<?php

    ob_start();
    system('ipconfig/all');
    $mycom=ob_get_contents(); 
    ob_clean(); 
    $findme = "Physical";
    $pmac = strpos($mycom, $findme); 
    $mac=substr($mycom,($pmac+36),17);

    echo $mac;
?>

This prints the mac address of client machine

You have to use execute immediate (dynamic sql).

DECLARE 
v_owner varchar2(40); 
v_table_name varchar2(40); 
cursor get_tables is 
select distinct table_name,user 
from user_tables 
where lower(user) = 'schema_name'; 
begin 
open get_tables; 
loop
    fetch get_tables into v_table_name,v_owner; 
    EXIT WHEN get_tables%NOTFOUND;
    execute immediate 'INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED) 
    SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'')     FROM ' || v_table_name; 
end loop;
CLOSE get_tables; 
END; 

You can avoid declaration of global variables by adding them directly to the global object:

(function(global) {

  ...

  global.varName = someValue;

  ...

}(this));

A disadvantage of this method is that global.varName won't exist until that specific line of code is executed, but that can be easily worked around.

You might also consider an application architecture where such globals are held in a closure common to all functions that need them, or as properties of a suitably accessible data storage object.

try block should be around open. Not around prompt.

while True:
    prompt = input("\n Hello to Sudoku valitator,"
    "\n \n Please type in the path to your file and press 'Enter': ")
    try:
        sudoku = open(prompt, 'r').readlines()
    except FileNotFoundError:
        print("Wrong file or file path")
    else:
        break

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

To make the answer more re-usable for things other than just the datepicker change function you can create a prototype to handle this for you.

// safety check to see if the prototype name is already defined
Function.prototype.method = function (name, func) {
    if (!this.prototype[name]) {
        this.prototype[name] = func;
        return this;
    }
};
Date.method('inPast', function () {
    return this < new Date($.now());// the $.now() requires jQuery
});

// including this prototype as using in example
Date.method('addDays', function (days) {
    var date = new Date(this);
    date.setDate(date.getDate() + (days));    
    return date;
});

If you dont like the safety check you can use the conventional way to define prototypes:

Date.prototype.inPast = function(){
    return this < new Date($.now());// the $.now() requires jQuery
}

Example Usage

var dt = new Date($.now());
var yesterday = dt.addDays(-1);
var tomorrow = dt.addDays(1);
console.log('Yesterday: ' + yesterday.inPast());
console.log('Tomorrow: ' + tomorrow.inPast());

Finally figured how to fix this after trying everything!

I noticed that for some reason the contentOffset of my tableview had a 'y' of -20 so when configuring my tableview: swift 3/4

tableView.contentOffset = .zero

Objective-C

self.tableView.contentOffset = CGPointMake(0, 44);

I had the very same problem and then I realized that programming in NodeJS is actually different than Python or Java as its based on JavaScript. I'll try to use simple concepts as there may be a few new folks that would be interested or may come to this question.

Let's look at the following code :

var http = require('http'); // (1)
exports.handler = function(event, context) {
  console.log('start request to ' + event.url)
  http.get(event.url,  // (2)
  function(res) {  //(3)
    console.log("Got response: " + res.statusCode);
    context.succeed();
  }).on('error', function(e) {
    console.log("Got error: " + e.message);
    context.done(null, 'FAILURE');
  });

  console.log('end request to ' + event.url); //(4)
}

Whenever you make a call to a method in http package (1) , it is created as event and this event gets it separate event. The 'get' function (2) is actually the starting point of this separate event.

Now, the function at (3) will be executing in a separate event, and your code will continue it executing path and will straight jump to (4) and finish it off, because there is nothing more to do.

But the event fired at (2) is still executing somewhere and it will take its own sweet time to finish. Pretty bizarre, right ?. Well, No it is not. This is how NodeJS works and its pretty important you wrap your head around this concept. This is the place where JavaScript Promises come to help.

You can read more about JavaScript Promises here. In a nutshell, you would need a JavaScript Promise to keep the execution of code inline and will not spawn new / extra threads.

Most of the common NodeJS packages have a Promised version of their API available, but there are other approaches like BlueBirdJS that address the similar problem.

The code that you had written above can be loosely re-written as follows.

'use strict';
console.log('Loading function');
var rp = require('request-promise');
exports.handler = (event, context, callback) => {    

    var options = {
    uri: 'https://httpbin.org/ip',
    method: 'POST',
    body: {

    },
    json: true 
};


    rp(options).then(function (parsedBody) {
            console.log(parsedBody);
        })
        .catch(function (err) {
            // POST failed... 
            console.log(err);
        });

    context.done(null);
};

Please note that the above code will not work directly if you will import it in AWS Lambda. For Lambda, you will need to package the modules with the code base too.

In case someone is still looking for something like this, I found that this new library called modin can help. It uses distributed computing that can help with the read. Here's a nice article comparing its functionality with pandas. It essentially uses the same functions as pandas.

import modin.pandas as pd
pd.read_csv(CSV_FILE_NAME)

    <html>
    <head>
        <title>Hello</title>

        <meta name="viewport" content="width=device-width, initial-scale=1">
        <meta charset="utf-8" />

       <link rel="stylesheet" href="app/css/styles.min.css" />   
       <script type="text/javascript" src="app/shims.js"></script>  
       <base href="/">
    </head>
     <body>
    <my-app>Loading...</my-app>
     <script type="text/javascript" src="app/app_libs_bundle.js"></script> 
    </body>

    </html>

 6) Now just copy your dist folder to '/www' in wamp server node need to copy node_modules in www.

import java.util.*;
import java.io.*;

public class Main {
    public static void main(String arg[])throws IOException{
        InputStreamReader isr = new InputStreamReader(System.in);
        BufferedReader br = new BufferedReader(isr);
        StringTokenizer st;
        String entrada = "";

        long x=0, y=0;

        while((entrada = br.readLine())!=null){
            st = new StringTokenizer(entrada," ");

            while(st.hasMoreTokens()){
                x = Long.parseLong(st.nextToken());
                y = Long.parseLong(st.nextToken());
            }

            System.out.println(x>y ?(x-y)+"":(y-x)+"");
        }
    }
}

This solution is a bit more efficient than the one above because it takes up the 2.128 and this takes 1.308 seconds to solve the problem.

Use Default toolkit for this

frame.setIconImage(Toolkit.getDefaultToolkit().getImage("Icon.png"));

With the sqldf package, R is capable of not only statistics, but serious data mining as well - assuming there is enough RAM on your machine.

And with the RServe package R becomes a regular TCP/IP server; so you can call R out of java (or any other language if you have the api). There is also a package in R to call java out or R.

Kind of late to the party, but, here is another solution, which autodetects if arguments.callee is available, and uses new Error().stack if not. Tested in chrome, safari and firefox.

2 variants - stackFN(n) gives you the name of the function n away from the immediate caller, and stackArray() gives you an array, stackArray()[0] being the immediate caller.

Try it out at http://jsfiddle.net/qcP9y/6/

// returns the name of the function at caller-N
// stackFN()  = the immediate caller to stackFN
// stackFN(0) = the immediate caller to stackFN
// stackFN(1) = the caller to stackFN's caller
// stackFN(2) = and so on
// eg console.log(stackFN(),JSON.stringify(arguments),"called by",stackFN(1),"returns",retval);
function stackFN(n) {
    var r = n ? n : 0, f = arguments.callee,avail=typeof f === "function",
        s2,s = avail ? false : new Error().stack;
    if (s) {
        var tl=function(x) { s = s.substr(s.indexOf(x) + x.length);},
        tr = function (x) {s = s.substr(0, s.indexOf(x) - x.length);};
        while (r-- >= 0) {
            tl(")");
        }
        tl(" at ");
        tr("(");
        return s;
    } else {
        if (!avail) return null;
        s = "f = arguments.callee"
        while (r>=0) {
            s+=".caller";
            r--;   
        }
        eval(s);
        return f.toString().split("(")[0].trim().split(" ")[1];
    }
}
// same as stackFN() but returns an array so you can work iterate or whatever.
function stackArray() {
    var res=[],f = arguments.callee,avail=typeof f === "function",
        s2,s = avail ? false : new Error().stack;
    if (s) {
        var tl=function(x) { s = s.substr(s.indexOf(x) + x.length);},
        tr = function (x) {s = s.substr(0, s.indexOf(x) - x.length);};
        while (s.indexOf(")")>=0) {
            tl(")");
            s2= ""+s;
            tl(" at ");
            tr("(");
            res.push(s);
            s=""+s2;
        }
    } else {
        if (!avail) return null;
        s = "f = arguments.callee.caller"
        eval(s);
        while (f) {
            res.push(f.toString().split("(")[0].trim().split(" ")[1]);
            s+=".caller";
            eval(s);
        }
    }
    return res;
}


function apple_makes_stuff() {
    var retval = "iPhones";
    var stk = stackArray();

    console.log("function ",stk[0]+"() was called by",stk[1]+"()");
    console.log(stk);
    console.log(stackFN(),JSON.stringify(arguments),"called by",stackFN(1),"returns",retval);
    return retval;
}



function apple_makes (){
    return apple_makes_stuff("really nice stuff");
}

function apple () {
    return apple_makes();
}

   apple();

L is a prefix used for wide strings. Each character uses several bytes (depending on the size of wchar_t). The encoding used is independent from this prefix. I mean it must not be necessarily UTF-16 unlike stated in other answers here.

In Spring Boot Rest Controller, I have resolved these by following Steps:

RestController :

@GetMapping("/statusByEmail/{email:.+}/")
public String statusByEmail(@PathVariable(value = "email") String email){
  //code
}

And From Rest Client:

Get http://mywebhook.com/statusByEmail/[email protected]/

Past : from sklearn.cross_validation (This package is deprecated in 0.18 version from 0.20 onwards it is changed to from sklearn import model_selection).

Present: from sklearn import model_selection

Example 2:

Past : from sklearn.cross_validation import cross_val_score (Version 0.18 which is deprecated)

Present : from sklearn.model_selection import cross_val_score

Try the following code.

public static IList<IList<T>> Split<T>(IList<T> source)
{
    return  source
        .Select((x, i) => new { Index = i, Value = x })
        .GroupBy(x => x.Index / 3)
        .Select(x => x.Select(v => v.Value).ToList())
        .ToList();
}

The idea is to first group the elements by indexes. Dividing by three has the effect of grouping them into groups of 3. Then convert each group to a list and the IEnumerable of List to a List of Lists

Use hashlib as hash() was designed to be used to:

quickly compare dictionary keys during a dictionary lookup

and therefore does not guarantee that it will be the same across Python implementations.

You will have to use something like below

#menu ul{_x000D_
  list-style: none;_x000D_
}_x000D_
#menu li{_x000D_
  display: inline;_x000D_
}_x000D_
 

<div id="menu">_x000D_
  <ul>_x000D_
    <li>First menu item</li>_x000D_
    <li>Second menu item</li>_x000D_
    <li>Third menu item</li>_x000D_
  </ul>_x000D_
</div>

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

String hashWith256(String textToHash) {
    MessageDigest digest = MessageDigest.getInstance("SHA-256");
    byte[] byteOfTextToHash = textToHash.getBytes(StandardCharsets.UTF_8);
    byte[] hashedByetArray = digest.digest(byteOfTextToHash);
    String encoded = Base64.getEncoder().encodeToString(hashedByetArray);
    return encoded;
}

Is it too late to answer. I would say, its better to go by Libraries like ClassPathScanningCandidateComponentProvider or like Scannotations

But even after somebody wants to try some hands on it with classLoader, I have written some on my own to print the annotations from classes in a package:

public class ElementScanner {

public void scanElements(){
    try {
    //Get the package name from configuration file
    String packageName = readConfig();

    //Load the classLoader which loads this class.
    ClassLoader classLoader = getClass().getClassLoader();

    //Change the package structure to directory structure
    String packagePath  = packageName.replace('.', '/');
    URL urls = classLoader.getResource(packagePath);

    //Get all the class files in the specified URL Path.
    File folder = new File(urls.getPath());
    File[] classes = folder.listFiles();

    int size = classes.length;
    List<Class<?>> classList = new ArrayList<Class<?>>();

    for(int i=0;i<size;i++){
        int index = classes[i].getName().indexOf(".");
        String className = classes[i].getName().substring(0, index);
        String classNamePath = packageName+"."+className;
        Class<?> repoClass;
        repoClass = Class.forName(classNamePath);
        Annotation[] annotations = repoClass.getAnnotations();
        for(int j =0;j<annotations.length;j++){
            System.out.println("Annotation in class "+repoClass.getName()+ " is "+annotations[j].annotationType().getName());
        }
        classList.add(repoClass);
    }
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
}

/**
 * Unmarshall the configuration file
 * @return
 */
public String readConfig(){
    try{
        URL url = getClass().getClassLoader().getResource("WEB-INF/config.xml");
        JAXBContext jContext = JAXBContext.newInstance(RepositoryConfig.class);
         Unmarshaller um =  jContext.createUnmarshaller();
         RepositoryConfig rc = (RepositoryConfig) um.unmarshal(new File(url.getFile()));
         return rc.getRepository().getPackageName();
        }catch(Exception e){
            e.printStackTrace();
        }
    return null;

}
}

And in config File, you put the package name and unmarshall it to a class .

In Javascript :

document.getElementById('searchField').value = '';

In jQuery :

$('#searchField').val('');

That should do it

OpenSSL has a horrible documentation with no code examples, but here you are:

#include <openssl/sha.h>

bool simpleSHA256(void* input, unsigned long length, unsigned char* md)
{
    SHA256_CTX context;
    if(!SHA256_Init(&context))
        return false;

    if(!SHA256_Update(&context, (unsigned char*)input, length))
        return false;

    if(!SHA256_Final(md, &context))
        return false;

    return true;
}

Usage:

unsigned char md[SHA256_DIGEST_LENGTH]; // 32 bytes
if(!simpleSHA256(<data buffer>, <data length>, md))
{
    // handle error
}

Afterwards, md will contain the binary SHA-256 message digest. Similar code can be used for the other SHA family members, just replace "256" in the code.

If you have larger data, you of course should feed data chunks as they arrive (multiple SHA256_Update calls).

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

Little addition, to run an interpreter from the same folder, still using #!hashbang in scripts.

As example a php7.2 executable copied from /usr/bin is in a folder along a hello script.

#!./php7.2
<?php

echo "Hello!"; 

To run it:

./hello

Which behave just as equal as:

./php7.2 hello

The proper solutions with good documentation can be the tools linuxdeploy and/or appimage, this is using this method under the hood.

From http://www.howtogeek.com/204166/how-to-configure-windows-to-work-with-powershell-scripts-more-easily:

Set the default value for the HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell to 0

You can return a task which gives you a stream as soon as it becomes available. It's a simplified solution, but it is a good starting point. It's thread safe.

private async Task<Stream> GetStreamAsync()
{
    try
    {
        return new FileStream("sample.mp3", FileMode.Open, FileAccess.Write);
    }
    catch (IOException)
    {
        await Task.Delay(TimeSpan.FromSeconds(1));
        return await GetStreamAsync();
    }
}

You can use this stream as usual:

using (var stream = await FileStreamGetter.GetStreamAsync())
{
    Console.WriteLine(stream.Length);
}

Of course it is an old post but just for people how will find it through search engine.

Another solution is to run it like this for IE9 and later

iexplore.exe" -noframemerging http://google.com
iexplore.exe" -noframemerging http://gmail.com

-noframemerging means run IE independently. For example it you want to run 2 browser and login as different username it will not work if you just run 2 IE. but with -noframemerging it will work. -noframemerging works for IE9 and later, for early versions like IE8 it is -nomerge

usually I create 1 but file like this run_ie.bat

"c:\Program Files (x86)\Internet Explorer\iexplore.exe" -noframemerging %1

and I create another bat file like this run_2_ie.bat

start run_ie.bat http://google.com
start run_ie.bat http://yahoo.com

This may help you, I have tried this when i got the same issue.

SELECT * FROM tab ORDER BY IIF(TRY_CAST(val AS INT) IS NULL, 1, 0),TRY_CAST(val AS INT);

At least in the current versions of PHPMailers, there's a function clearReplyTos() to empty the reply-to array.

    $mail->ClearReplyTos();
    $mail->addReplyTo([email protected], 'EXAMPLE');

If you want to retrieve your value from an list box you should try this:

String itemSelected = numberListBox.GetItemText(numberListBox.SelectedItem);

Try adding the line c = cv.WaitKey(10) at the bottom of your repeat() method.

This waits for 10 ms for the user to enter a key. Even if you're not using the key at all, put this in. I think there just needed to be some delay, so time.sleep(10) may also work.

In regards to the camera index, you could do something like this:

for i in range(3):
    capture = cv.CaptureFromCAM(i)
    if capture: break

This will find the index of the first "working" capture device, at least for indices from 0-2. It's possible there are multiple devices in your computer recognized as a proper capture device. The only way I know of to confirm you have the right one is manually looking at your light. Maybe get an image and check its properties?

To add a user prompt to the process, you could bind a key to switching cameras in your repeat loop:

import cv

cv.NamedWindow("w1", cv.CV_WINDOW_AUTOSIZE)
camera_index = 0
capture = cv.CaptureFromCAM(camera_index)

def repeat():
    global capture #declare as globals since we are assigning to them now
    global camera_index
    frame = cv.QueryFrame(capture)
    cv.ShowImage("w1", frame)
    c = cv.WaitKey(10)
    if(c=="n"): #in "n" key is pressed while the popup window is in focus
        camera_index += 1 #try the next camera index
        capture = cv.CaptureFromCAM(camera_index)
        if not capture: #if the next camera index didn't work, reset to 0.
            camera_index = 0
            capture = cv.CaptureFromCAM(camera_index)

while True:
    repeat()

disclaimer: I haven't tested this so it may have bugs or just not work, but might give you at least an idea of a workaround.

Ive modifiet Lukas Knuth's solution a little:

1) There's no need to subclass the webview,

2) the code will crash during bytecode verification on some Android 1.6 devices if you don't put nonexistant methods in seperate classes

3) Zoom controls will still appear if the user scrolls up/down a page. I simply set the zoom controller container to visibility GONE

  wv.getSettings().setSupportZoom(true);
  wv.getSettings().setBuiltInZoomControls(true);
  if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
    // Use the API 11+ calls to disable the controls
    // Use a seperate class to obtain 1.6 compatibility
    new Runnable() {
      public void run() {
        wv.getSettings().setDisplayZoomControls(false);
      }
    }.run();
  } else {
    final ZoomButtonsController zoom_controll =
        (ZoomButtonsController) wv.getClass().getMethod("getZoomButtonsController").invoke(wv, null);
    zoom_controll.getContainer().setVisibility(View.GONE);
  }

You can do it by using name attibute, class, id or just universal checkbox; If you want to count only checked number of checkbox.

By the class name :

var countChk = $('checkbox.myclassboxName:checked').length;

By name attribute :

var countByName= $('checkbox[name=myAllcheckBoxName]:checked').length;

Complete code

$('checkbox.className').blur(function() {
    //count only checked checkbox 
    $('checkbox[name=myAllcheckBoxName]:checked').length;
});

Swift 3

@IBOutlet weak var webview: UIWebView!
webview.loadRequest(URLRequest(url: URL(string: "https://www.yourvideo.com")!))

String path = "C:"+File.separator+"hello";
String fname= path+File.separator+"abc.txt";
    File f = new File(path);
    File f1 = new File(fname);

    f.mkdirs() ;
    try {
        f1.createNewFile();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

This should create a new file inside a directory

I don't have an Ubuntu box, but on Red Hat Linux you can see all running services by running the following command:

service --status-all

On the list the + indicates the service is running, - indicates service is not running, ? indicates the service state cannot be determined.

You can try SQLyog 'Execute SQL script' tool to import sql/dump files.

use binary search

public class FindSqrt {

    public static void main(String[] strings) {

        int num = 10000;
        System.out.println(sqrt(num, 0, num));
    }

    private static int sqrt(int num, int min, int max) {
        int middle = (min + max) / 2;
        int x = middle * middle;
        if (x == num) {
            return middle;
        } else if (x < num) {
            return sqrt(num, middle, max);
        } else {
            return sqrt(num, min, middle);
        }
    }
}

You have done it backwards, it should be:

amount = invest(amount,top_company(5,year,year+1),year)

Your form is also missing '{{csrf_field()}}'

While many of the suggestions work when converting 2 -> 4 space. I ran into some issues when converting 4 -> 2.

Here's what I ended up using:

Sublime Text 3/Packages/User/to-2.sublime-macro

[
  { "args": null, "command": "select_all" },
  { "args": { "set_translate_tabs": true }, "command": "unexpand_tabs" },
  { "args": { "setting": "tab_size", "value": 1 }, "command": "set_setting" },
  { "args": { "set_translate_tabs": true }, "command": "expand_tabs" },
  { "args": { "setting": "tab_size", "value": 2 }, "command": "set_setting" }
]

To open a new instance with your project loaded from terminal, just type code <directory-path>

Not best practice..but works fine...

<ComboBox GotFocus="Focused"  x:Name="combobox1" HorizontalAlignment="Left" Margin="8,29,0,0" VerticalAlignment="Top" Width="128" Height="117"/>

Code behind

public partial class MainWindow : Window
{
    bool clearonce = true;
    bool fillonce = true;
    public MainWindow()
    {
        this.InitializeComponent();          
        combobox1.Items.Insert(0, " -- Select Team --");
        combobox1.SelectedIndex = 0;
    }

    private void Focused(object sender, RoutedEventArgs e)
    {
            if(clearonce)
            {
                combobox1.Items.Clear();
                clearonce = false;
            }
            if (fillonce)
            {
              //fill the combobox items here 
                for (int i = 0; i < 10; i++)
                {
                    combobox1.Items.Insert(i, i);
                }
                fillonce = false;
            }           
    }
}

use this package and check the docs:

https://laravelcollective.com/docs/5.2/html#drop-down-lists

form you html , you need use this mark

{!! Form::select('size', array('L' => 'Large', 'S' => 'Small'), 'S'); !!}

If your SQL database allows Null values for that field try using int? value like that :

if (this.txtboxname.Text == "" || this.txtboxname.text == null)
     value = null;
else
     value = Convert.ToInt32(this.txtboxname.Text);

Take care that Convert.ToInt32 of a null value returns 0 !

Convert.ToInt32(null) returns 0

Currently I Use following code :

Bitmap bMap = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MICRO_KIND);

But I found better solution with Glide library with following code ( It also cache your image and have better performance than previous approach )

Glide.with(context)
                .load(uri)
                .placeholder(R.drawable.ic_video_place_holder)
                .into(imageView);

Another simple way

function is_json($str)
{
    return is_array(json_decode($str,true));
}

I posted another solution here Which is the best approach to insert an vector (svg) graph into a react native application, This approach use a vector font(from svg) instead a svg file. PS: Its works great in ios and android, and you also can change the color and size of your vector icon.

If you want to insert a svg directly into your app, you can try a 3rd party library : react-native-svg. With more than 3k stars in github it's one of the best approach.

• install:
  • npm i react-native-svg
  • npm i react-native-svg-uri
• link the to native:
  • react-native link react-native-svg

And here's a sample:

import * as React from 'react';
import SvgUri from 'react-native-svg-uri';
import testSvg from './test.svg';
export default () => (
  <SvgUri
    width="200"
    height="200"
    svgXmlData={testSvg}
  />
);

type data1.csv > combined.csv
type data2.csv >> combined.csv
type data3.csv >> combined.csv
type data4.csv >> combined.csv

etc.

Assume that your using files without headers and all files have the same columns.

You can also use the following code to open new page in new tab.

<asp:Button ID="Button1" runat="server" Text="Go" 
  OnClientClick="window.open('yourPage.aspx');return false;" 
  onclick="Button3_Click" />

And just call Response.Redirect("yourPage.aspx"); behind button event.

Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

Encoding "Mary had" to Base 64

In this example we are using a simple text string ("Mary had") but the principle holds no matter what the data is (e.g. graphics file). To convert each 24 bits of input data to 32 bits of output, Base 64 encoding splits the 24 bits into 4 chunks of 6 bits. The first problem we notice is that "Mary had" is not a multiple of 3 bytes - it is 8 bytes long. Because of this, the last group of bits is only 4 bits long. To remedy this we add two extra bits of '0' and remember this fact by putting a '=' at the end. If the text string to be converted to Base 64 was 7 bytes long, the last group would have had 2 bits. In this case we would have added four extra bits of '0' and remember this fact by putting '==' at the end.

Try this:
CSS:

#content {
  margin: 0 auto;
  border: 1px solid red;
  width:800px;
  position:absolute;
  bottom:0px;
  top:0px;
  overflow:auto
}

HTML:

<body>
<div id="content">
...content goes here...
</div>
<body>

If you don't like absolute positioning in this case, just can play with making a parent and child div to this one, both with position:relative.

EDIT: Below should work (I just put the css inline for the moment):

<div style="margin:0 auto; width:800px; height:100%; overflow:hidden">
<div style="border: 1px solid red; width:800px; position:absolute; bottom:0px; top:0px; overflow:auto">
...content goes here...
</div>
</div>

You can use the scales package just for this operation (without loading it with require or library)

scales::percent(m)

if we update <select> constantly and we need to save previous value :

var newOptions = {
    'Option 1':'value-1',
    'Option 2':'value-2'
};

var $el = $('#select');
var prevValue = $el.val();
$el.empty();
$.each(newOptions, function(key, value) {
   $el.append($('<option></option>').attr('value', value).text(key));
   if (value === prevValue){
       $el.val(value);
   }
});
$el.trigger('change');

Take care with gradle daemon, you have to stop it before clear and re-run gradle.

Stop first daemon:

./gradlew --stop

Clean cache using:

rm -rf ~/.gradle/caches/

Run again you compilation

This code is workig fine for me, hope it will help you too.

first you have to assign blank value in first option. i.e. Select here.than only required will work.

You can define the behavior globally:

$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";

So you don't have to redefine it every time:

$http.post("/handle/post", {
    foo: "FOO",
    bar: "BAR"
}).success(function (data, status, headers, config) {
    // TODO
}).error(function (data, status, headers, config) {
    // TODO
});

std::fill is one way. Takes two iterators and a value to fill the region with. That, or the for loop, would (I suppose) be the more C++ way.

For setting an array of primitive integer types to 0 specifically, memset is fine, though it may raise eyebrows. Consider also calloc, though it's a bit inconvenient to use from C++ because of the cast.

For my part, I pretty much always use a loop.

(I don't like to second-guess people's intentions, but it is true that std::vector is, all things being equal, preferable to using new[].)

Don't waste your time, you can use Resource Bundle plugin in Eclipse

Gallery is the best solution, i have tried it. I was working on one mail app, in which mails in the inbox where displayed as listview, i wanted an horizontal view, i just converted listview to gallery and everything worked fine as i needed without any errors. For the scroll effect i enabled gesture listener for the gallery. I hope this answer may help u.

RemoteEndPoint is a property, its type is System.Net.EndPoint which inherits from System.Net.IPEndPoint.

If you take a look at IPEndPoint's members, you'll see that there's an Address property.

If you don't care about vertex reuse, you could have two output files--one for vertices and one for triangles. Then append the triangle file to the vertex file when you are done.

Make sure you take into account that adding this tag,

<meta http-equiv="X-UA-Compatible" content="IE=Edge">

may only allow compatibility with the latest versions. It all depends on your libraries

It greatly reduces your level of confidence about security.

If your SQL doesn't support NULLS FIRST or NULLS LAST, the simplest way to do this is to use the value IS NULL expression:

ORDER BY Next_Contact_Date IS NULL, Next_Contact_Date

to put the nulls at the end (NULLS LAST) or

ORDER BY Next_Contact_Date IS NOT NULL, Next_Contact_Date

to put the nulls at the front. This doesn't require knowing the type of the column and is easier to read than the CASE expression.

EDIT: Alas, while this works in other SQL implementations like PostgreSQL and MySQL, it doesn't work in MS SQL Server. I didn't have a SQL Server to test against and relied on Microsoft's documentation and testing with other SQL implementations. According to Microsoft, value IS NULL is an expression that should be usable just like any other expression. And ORDER BY is supposed to take expressions just like any other statement that takes an expression. But it doesn't actually work.

The best solution for SQL Server therefore appears to be the CASE expression.

    String line;_x000D_
    Process process = Runtime.getRuntime().exec("ps -e");_x000D_
    process.getOutputStream().close();_x000D_
    BufferedReader input =_x000D_
            new BufferedReader(new InputStreamReader(process.getInputStream()));_x000D_
    while ((line = input.readLine()) != null) {_x000D_
        System.out.println(line); //<-- Parse data here._x000D_
    }_x000D_
    input.close();

We have to use process.getOutputStream.close() otherwise it will get locked in while loop.

Or without ( and the need to escape it:

find . -not -name "*.exe" -not -name "*.dll"

and to also exclude the listing of directories

find . -not -name "*.exe" -not -name "*.dll" -not -type d

or in positive logic ;-)

find . -not -name "*.exe" -not -name "*.dll" -type f

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

Just to complete the existing answers, I'd suggest using select instead of nonblocking sockets. The point is that nonblocking sockets complicate stuff (except perhaps sending), so I'd say there is no reason to use them at all. If you regularly have the problem that your app is blocked waiting for IO, I would also consider doing the IO in a separate thread in the background.

Did you consider using nginx (or other event based web server) instead of apache?

nginx shall allow higher number of connections and consume much less resources (as it is event based and does not create separate process per connection). Anyway, you will need some processes, doing real work (like WSGI servers or so) and if they stay on the same server as the front end web server, you only shift the performance problem to a bit different place.

Latest apache version shall allow similar solution (configure it in event based manner), but this is not my area of expertise.

A cast, as Blaz Bratanic suggested:

size_t data = 99999999;
int convertdata = static_cast<int>(data);

is likely to silence the warning (though in principle a compiler can warn about anything it likes, even if there's a cast).

But it doesn't solve the problem that the warning was telling you about, namely that a conversion from size_t to int really could overflow.

If at all possible, design your program so you don't need to convert a size_t value to int. Just store it in a size_t variable (as you've already done) and use that.

Converting to double will not cause an overflow, but it could result in a loss of precision for a very large size_t value. Again, it doesn't make a lot of sense to convert a size_t to a double; you're still better off keeping the value in a size_t variable.

(R Sahu's answer has some suggestions if you can't avoid the cast, such as throwing an exception on overflow.)

Try looking at decode string encoded in utf-8 format in android but it doesn't look like your string is encoded with anything particular. What do you think the output should be?

First, Identify the user you are logged in as:

 select user();
 select current_user();

The result for the first command is what you attempted to login as, the second is what you actually connected as. Confirm that you are logged in as root@localhost in mysql.

Grant_priv to root@localhost. Here is how you can check.

mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
+-----------+------------------+-------------------------------------------+------------+------------+
| host      | user             | password                                  | Grant_priv | Super_priv |
+-----------+------------------+-------------------------------------------+------------+------------+
| localhost | root             | ***************************************** | N          | Y          |
| localhost | debian-sys-maint | ***************************************** | Y          | Y          |
| localhost | staging          | ***************************************** | N          | N          |
+-----------+------------------+-------------------------------------------+------------+------------+

You can see that the Grant_priv is set to N for root@localhost. This needs to be Y. Below is how to fixed this:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';

I logged back in, it was fine.

For those who want to add noise to a multi-dimensional dataset loaded within a pandas dataframe or even a numpy ndarray, here's an example:

# clean_signal = pd.read_csv("your_data.csv")   
clean_signal = pd.DataFrame([[1,2],[3,4]], columns=list('AB'), dtype=float) 
print(clean_signal)
"""
print output: 
    A    B
0  1.0  2.0
1  3.0  4.0
"""
import numpy as np 
mu, sigma = 0, 0.1 
# creating a noise with the same dimension as the dataset (2,2) 
noise = np.random.normal(mu, sigma, [2,2]) 
print(noise)

"""
print output: 
array([[-0.11114313,  0.25927152],
       [ 0.06701506, -0.09364186]])
"""
signal = clean_signal + noise
print(signal)
"""
print output: 
          A         B

No. Any valid string is a valid key. It can even have " as long as you escape it:

{"The \"meaning\" of life":42}

There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.

update 2 ::slotted

::slotted is now supported by all new browsers and can be used with ViewEncapsulation.ShadowDom

https://developer.mozilla.org/en-US/docs/Web/CSS/::slotted

update 1 ::ng-deep

/deep/ was deprecated and replaced by ::ng-deep.

::ng-deep is also already marked deprecated, but there is no replacement available yet.

When ViewEncapsulation.Native is properly supported by all browsers and supports styling accross shadow DOM boundaries, ::ng-deep will probably be discontinued.

original

Angular adds all kinds of CSS classes to the HTML it adds to the DOM to emulate shadow DOM CSS encapsulation to prevent styles of bleeding in and out of components. Angular also rewrites the CSS you add to match these added classes. For HTML added using [innerHTML] these classes are not added and the rewritten CSS doesn't match.

As a workaround try

• for CSS added to the component

/* :host /deep/ mySelector { */
:host ::ng-deep mySelector { 
  background-color: blue;
}

• for CSS added to index.html

/* body /deep/ mySelector { */
body ::ng-deep mySelector {
  background-color: green;
}

>>> (and the equivalent/deep/ but /deep/ works better with SASS) and ::shadow were added in 2.0.0-beta.10. They are similar to the shadow DOM CSS combinators (which are deprecated) and only work with encapsulation: ViewEncapsulation.Emulated which is the default in Angular2. They probably also work with ViewEncapsulation.None but are then only ignored because they are not necessary. These combinators are only an intermediate solution until more advanced features for cross-component styling is supported.

Another approach is to use

@Component({
  ...
  encapsulation: ViewEncapsulation.None,
})

for all components that block your CSS (depends on where you add the CSS and where the HTML is that you want to style - might be all components in your application)

Example Plunker

I had the same error as the OP, but digging through the logs I could see sh: node: command not found.

It turns out that the /usr/bin/node program (symlink) is no longer installed with apt install nodejs. Once symlinked /usr/bin/node' tonodejs,npm install -g @angular/cli` succeeded.

The proper way to install this on debian is apt install nodejs-legacy.

is it still actual?

Trick to update props if they are array :

  Text,
  View,
  Button
} from 'react-native';

class Counter extends Component {
  constructor(props) {
    super(props);
      this.state = {
        count: this.props.count
      }
    }
  increment(){
    console.log("this.props.count");
    console.log(this.props.count);
    let count = this.state.count
    count.push("new element");
    this.setState({ count: count})
  }
  render() {

    return (
      <View style={styles.container}>
        <Text>{ this.state.count.length }</Text>
        <Button
          onPress={this.increment.bind(this)}
          title={ "Increase" }
        />
      </View>
    );
  }
}

Counter.defaultProps = {

You are returning Observable<Product> and expecting it to be Product[] inside subscribe callback.

The Type returned from http.get() and getProducts() should be Observable<Product[]>

public getProducts(): Observable<Product[]> {
    return this.http.get<Product[]>(`api/products/v1/`);
}

You can customize your own version on the Bootstrap official website.

I faced the error "TypeError: 'NoneType' object is not callable " but for a different issue. With the above clues, i was able to debug and got it right! The issue that i faced was : I had the custome Library written and my file wasnt recognizing it although i had mentioned it

example: 
Library           ../../../libraries/customlibraries/ExtendedWaitKeywords.py
the keywords from my custom library were recognized and that error  was resolved only after specifying the complete path, as it was not getting the callable function.

Extending answer of @MichaelLaCroix when a scenario is that the components can't communicate between any sort of parent-child relationship, the documentation recommends setting up a global event system.

In the case of <Filters /> and <TopBar /> don't have any of the above relationship, a simple global emitter could be used like this:

componentDidMount - Subscribe to event

componentWillUnmount - Unsubscribe from event

Working solution is by using in-build: panelClass attribute and set styles in global style.css (with !important):

https://material.angular.io/components/select/api

/* style.css */
.matRole .mat-option-text {
  height: 4em !important;
}

<mat-select panelClass="matRole">...

Tensorflow also implemented functions for resizing/padding images tf.image.pad tf.pad.

padded_image = tf.image.pad_to_bounding_box(image, top_padding, left_padding, target_height, target_width)

padded_image = tf.pad(image, paddings, "CONSTANT")

These functions work just like other input-pipeline features of tensorflow and will work much better for machine learning applications.

After trying all the above and using the answer from @Aaron Hall, I was getting memory errors for a ~90 Mb file on a computer running Window 10, 8 Gb RAM and Python 3.5 32-bit. I was recommended by a colleague to use numpy instead and it works wonders.

By far, the fastest to read an entire binary file (that I have tested) is:

import numpy as np

file = "binary_file.bin"
data = np.fromfile(file, 'u1')

Reference

Multitudes faster than any other methods so far. Hope it helps someone!

To check for an exact match you would use num == line. But line has an end-of-line character \n or \r\n which will not be in num since raw_input strips the trailing newline. So it may be convenient to remove all whitespace at the end of line with

line = line.rstrip()

with open("file.txt") as search:
    for line in search:
        line = line.rstrip()  # remove '\n' at end of line
        if num == line:
            print(line )

Try decoding it first, then encoding:

apple.decode('iso-8859-1').encode('utf8')

This works for me in Kotlin:

when(list.get(0)).thenThrow(new ArrayIndexOutOfBoundsException());

Note : Throw any defined exception other than Exception()

Using pretty much the same approach as used by Burnash, for the final result you can use ...

=regexextract(A1,"[0-9]+")+A2

where A1 houses the string with text and number and A2 houses the date of interest

public String convertImageToBase64(String filePath) {
    byte[] fileContent = new byte[0];
    String base64encoded = null;
    try {
        fileContent = FileUtils.readFileToByteArray(new File(filePath));
    } catch (IOException e) {
        log.error("Error reading file: {}", filePath);
    }
    try {
        base64encoded = Base64.getEncoder().encodeToString(fileContent);
    } catch (Exception e) {
        log.error("Error encoding the image to base64", e);
    }
    return base64encoded;
}

 echo "$x"

The below code worked.

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Add this code before calling videoView.start(). With this the video activity runs in full screen mode in most of the cases. But if the title bar is still displayed then change your theme in your manifest to this.

    android:theme="@style/Theme.AppCompat.NoActionBar">

import codecs

 ...

fichier = codecs.open(filePath, "r", encoding="utf-8")

 ...

fichierTemp = codecs.open("tempASCII", "w", encoding="ascii", errors="ignore")
fichierTemp.write(contentOfFile)

 ...

var example = "I am too long string";
var result;

// Slice is JS function
result = example.slice(0, 10)+'...'; //if you need dots after the string you can add

Result variable contains "I am too l..."

In Swift 2:

extension NSMutableURLRequest {
    func setAuthorizationHeader(username username: String, password: String) -> Bool {
        guard let data = "\(username):\(password)".dataUsingEncoding(NSUTF8StringEncoding) else { return false }

        let base64 = data.base64EncodedStringWithOptions([])
        setValue("Basic \(base64)", forHTTPHeaderField: "Authorization")
        return true
    }
}

I had originally asked myself the question "Do I need a PDB file deployed to my customer's machine?", and after reading this post, decided to exclude the file.

Everything worked fine, until today, when I was trying to figure out why a message box containing an Exception.StackTrace was missing the file and line number information - necessary for troubleshooting the exception. I re-read this post and found the key nugget of information: that although the PDB is not necessary for the app to run, it is necessary for the file and line numbers to be present in the StackTrace string. I included the PDB file in the executable folder and now all is fine.

I don’t know if it helps anybody but I always like to visualize concepts in my head to better understand them. So as I have a little son I visualize iterable/iterator concept with bricks and white paper.

Suppose we are in the dark room and on the floor we have bricks for my son. Bricks of different size, color, does not matter now. Suppose we have 5 bricks like those. Those 5 bricks can be described as an object – let’s say bricks kit. We can do many things with this bricks kit – can take one and then take second and then third, can change places of bricks, put first brick above the second. We can do many sorts of things with those. Therefore this bricks kit is an iterable object or sequence as we can go through each brick and do something with it. We can only do it like my little son – we can play with one brick at a time. So again I imagine myself this bricks kit to be an iterable.

Now remember that we are in the dark room. Or almost dark. The thing is that we don’t clearly see those bricks, what color they are, what shape etc. So even if we want to do something with them – aka iterate through them – we don’t really know what and how because it is too dark.

What we can do is near to first brick – as element of a bricks kit – we can put a piece of white fluorescent paper in order for us to see where the first brick-element is. And each time we take a brick from a kit, we replace the white piece of paper to a next brick in order to be able to see that in the dark room. This white piece of paper is nothing more than an iterator. It is an object as well. But an object with what we can work and play with elements of our iterable object – bricks kit.

That by the way explains my early mistake when I tried the following in an IDLE and got a TypeError:

 >>> X = [1,2,3,4,5]
 >>> next(X)
 Traceback (most recent call last):
    File "<pyshell#19>", line 1, in <module>
      next(X)
 TypeError: 'list' object is not an iterator

List X here was our bricks kit but NOT a white piece of paper. I needed to find an iterator first:

>>> X = [1,2,3,4,5]
>>> bricks_kit = [1,2,3,4,5]
>>> white_piece_of_paper = iter(bricks_kit)
>>> next(white_piece_of_paper)
1
>>> next(white_piece_of_paper)
2
>>>

Don’t know if it helps, but it helped me. If someone could confirm/correct visualization of the concept, I would be grateful. It would help me to learn more.

My problem was that I needed to Reset Window Layout.

This is quite simple to do and the answer is available in other queries. For those of you who are viewing this:

select entries from my_entries where id='42' INTO OUTFILE 'bishwas.txt';

1. mydata$sCode is a vector, it's why nrow output is NULL.
2. mydata[mydata$sCode == 'CA',] returns data.frame where sCode == 'CA'. sCode includes character. That's why sum gives you the error.

3. subset(mydata, sCode='CA', select=c(sCode)), you should use sCode=='CA' instead sCode='CA'. Then subset returns you vector where sCode equals CA, so you should use

   length(subset(na.omit(mydata), sCode='CA', select=c(sCode)))

Or you can try this: sum(na.omit(mydata$sCode) == "CA")

There are some changes required to JavaScript code to handle rendering based on user liking or not liking the page mandated by Facebook moving to Auth2.0 authorization.

Change is fairly simple:-

sessions has to be replaced by authResponse and uid by userID

Moreover given the requirement of the code and some issues faced by people(including me) in general with FB.login, use of FB.getLoginStatus is a better alternative. It saves query to FB in case user is logged in and has authenticated your app.

Refer to Response and Sessions Object section for info on how this might save query to FB server. http://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus/

Issues with FB.login and its fixes using FB.getLoginStatus. http://forum.developers.facebook.net/viewtopic.php?id=70634

Here is the code posted above with changes which worked for me.

$(document).ready(function(){
    FB.getLoginStatus(function(response) {
        if (response.status == 'connected') {
            var user_id = response.authResponse.userID;
            var page_id = "40796308305"; //coca cola
            var fql_query = "SELECT uid FROM page_fan WHERE page_id =" + page_id + " and uid=" + user_id;
            var the_query = FB.Data.query(fql_query);

            the_query.wait(function(rows) {

                if (rows.length == 1 && rows[0].uid == user_id) {
                    $("#container_like").show();

                    //here you could also do some ajax and get the content for a "liker" instead of simply showing a hidden div in the page.

                } else {
                    $("#container_notlike").show();
                    //and here you could get the content for a non liker in ajax...
                }
            });
        } else {
            // user is not logged in
        }
    });

});

I had to modify Endy's directive so that I can get Last Modified, lastModifiedDate, name, size, type, and data as well as be able to get an array of files. For those of you that needed these extra features, here you go.

UPDATE: I found a bug where if you select the file(s) and then go to select again but cancel instead, the files are never deselected like it appears. So I updated my code to fix that.

 .directive("fileread", function () {
        return {
            scope: {
                fileread: "="
            },
            link: function (scope, element, attributes) {
                element.bind("change", function (changeEvent) {
                    var readers = [] ,
                        files = changeEvent.target.files ,
                        datas = [] ;
                    if(!files.length){
                        scope.$apply(function () {
                            scope.fileread = [];
                        });
                        return;
                    }
                    for ( var i = 0 ; i < files.length ; i++ ) {
                        readers[ i ] = new FileReader();
                        readers[ i ].index = i;
                        readers[ i ].onload = function (loadEvent) {
                            var index = loadEvent.target.index;
                            datas.push({
                                lastModified: files[index].lastModified,
                                lastModifiedDate: files[index].lastModifiedDate,
                                name: files[index].name,
                                size: files[index].size,
                                type: files[index].type,
                                data: loadEvent.target.result
                            });
                            if ( datas.length === files.length ){
                                scope.$apply(function () {
                                    scope.fileread = datas;
                                });
                            }
                        };
                        readers[ i ].readAsDataURL( files[i] );
                    }
                });

            }
        }
    });

Here is a simple function that checks input for INT and RANGE. Here, returns 'True' if input is integer between 1-100, 'False' otherwise

def validate(userInput):

    try:
        val = int(userInput)
        if val > 0 and val < 101:
            valid = True
        else:
            valid = False

    except Exception:
        valid = False

    return valid

why kill -9 : the number 9 in the list of signals has been chosen to be SIGKILL in reference to "kill the 9 lives of a cat".

If you're array structure will always be multi-dimensional in that exact fashion, then we can iterate through the elements like such:

$fh = fopen('somefile.csv', 'w') or die('Cannot open the file');

for( $i=0; $i<count($arr); $i++ ){
    $str = implode( ',', $arr[$i] );
    fwrite( $fh, $str );
    fwrite( $fh, "\n" );
}
fclose($fh);

That's one way to do it ... you could do it manually but this way is quicker and easier to understand and read.

Then you would manage your headers something what complex857 is doing to spit out the file. You could then delete the file using unlink() if you no longer needed it, or you could leave it on the server if you wished.

Iterables.get(yourC, indexYouWant)

Because really, if you're using Collections, you should be using Google Collections.

Visit https://play.golang.org/p/dx6PTtuBXQW

package main

import (
    "fmt"
    "sort"
)

func main() {
    mapEg := map[string]string{"c":"a","a":"c","b":"b"}
    keys := make([]string, 0, len(mapEg))
    for k := range mapEg {
        keys = append(keys, k)
    }
    sort.Strings(keys)
    fmt.Println(keys)
}

My utils function for get view location, it will return a Point object with x value and y value

public static Point getLocationOnScreen(View view){
    int[] location = new int[2];
    view.getLocationOnScreen(location);
    return new Point(location[0], location[1]);
}

Using

Point viewALocation = getLocationOnScreen(viewA);

I would try to give them all display: block; attribute and using float: left;.

You can then set width and/or height as you like. You can even specify some vertical-alignment rules.

Or if you want to bound the value to the interval:

public static T EnsureRange<T>(this T value, T min, T max) where T : IComparable<T>
    {
        if (value.CompareTo(min) < 0)
            return min;
        else if (value.CompareTo(max) > 0)
            return max;
        else
            return value;
    }

It is like two-sided Math.Min/Max

After hours of googling: No, it's not possible without JavaScript. The animation-iteration-count: 1; is internally saved in the animation shothand attribute, which gets resetted and overwritten on :hover. When we blur the <a> and release the :hover the old class reapplies and therefore again resets the animation attribute.

There sadly is no way to save a certain attribute states across element states.

You'll have to use JavaScript.

Since I needed to analyze fat jars I was interested in the version of each individual class in a jar file. Therefore I took Joe Liversedge approach https://stackoverflow.com/a/27877215/1497139 and combined it with David J. Liszewski' https://stackoverflow.com/a/3313839/1497139 class number version table to create a bash script jarv to show the versions of all class files in a jar file.

You get that message because you made changes in your local master and you didn't push them to remote. You have several ways to "solve" it and it normally depends on how your workflow looks like:

• In a good workflow your remote copy of master should be the good one while your local copy of master is just a copy of the one in remote. Using this workflow you'll never get this message again.
• If you work in another way and your local changes should be pushed then just git push origin assuming origin is your remote
• If your local changes are bad then just remove them or reset your local master to the state on remote git reset --hard origin/master

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

I think the params config parameter won't work here since it adds the string to the url instead of the body but to add to what Infeligo suggested here is an example of the global override of a default transform (using jQuery param as an example to convert the data to param string).

Set up global transformRequest function:

var app = angular.module('myApp');

app.config(function ($httpProvider) {
    $httpProvider.defaults.transformRequest = function(data){
        if (data === undefined) {
            return data;
        }
        return $.param(data);
    }
});

That way all calls to $http.post will automatically transform the body to the same param format used by the jQuery $.post call.

Note you may also want to set the Content-Type header per call or globally like this:

$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';

Sample non-global transformRequest per call:

    var transform = function(data){
        return $.param(data);
    }

    $http.post("/foo/bar", requestData, {
        headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'},
        transformRequest: transform
    }).success(function(responseData) {
        //do stuff with response
    });

basically, I think that there is a solution which is much easier and straight forward, for any given polygon, lets say consist of four vertices(p1,p2,p3,p4), find the two extreme opposite vertices in the polygon, in another words, find the for example the most top left vertex (lets say p1) and the opposite vertex which is located at most bottom right (lets say ). Hence, given your testing point C(x,y), now you have to make double check between C and p1 and C and p4:

if cx > p1x AND cy > p1y ==> means that C is lower and to right of p1 next if cx < p2x AND cy < p2y ==> means that C is upper and to left of p4

conclusion, C is inside the rectangle.

Thanks :)

Update: Angular 1.1.5 added a ternary operator, this answer is correct only to versions preceding 1.1.5. For 1.1.5 and later, see the currently accepted answer.

Before Angular 1.1.5:

The form of a ternary in angularjs is:

((condition) && (answer if true) || (answer if false))

An example would be:

<ul class="nav">
    <li>
        <a   href="#/page1" style="{{$location.path()=='/page2' && 'color:#fff;' || 'color:#000;'}}">Goals</a>
    </li>
    <li>
        <a   href="#/page2" style="{{$location.path()=='/page2' && 'color:#fff;' || 'color:#000;'}}">Groups</a>
    </li>
</ul>

or:

 <li  ng-disabled="currentPage == 0" ng-click="currentPage=0"  class="{{(currentPage == 0) && 'disabled' || ''}}"><a> << </a></li>

There is another method with Java 8 in a null-safe way.

List<SomeBean> wsListCopy = Optional.ofNullable(wsList)
    .map(Collection::stream)
    .orElseGet(Stream::empty)
    .collect(Collectors.toList());

If you want to skip one element.

List<SomeBean> wsListCopy = Optional.ofNullable(wsList)
    .map(Collection::stream)
    .orElseGet(Stream::empty)
    .skip(1)
    .collect(Collectors.toList());

With Java 9+, the stream method of Optional can be used

Optional.ofNullable(wsList)
    .stream()
    .flatMap(Collection::stream)
    .collect(Collectors.toList())

I use this with fold in indent mode :

v open Visual mode anywhere on the block

zaza toogle it twice

git clean -d -f -i is the best way to do it.

This will help to clean in a more controlled manner.

-i stands for interactive.

Simply you cannot do it with FF3.

The other option could be using applet or other controls to select and upload files.

Swift 5 for cocoa

        // Getting the Contents of a Directory in a Single Batch Operation

        let bundleRoot = Bundle.main.bundlePath
        let url = URL(string: bundleRoot)
        let properties: [URLResourceKey] = [ URLResourceKey.localizedNameKey, URLResourceKey.creationDateKey, URLResourceKey.localizedTypeDescriptionKey]
        if let src = url{
            do {
                let paths = try FileManager.default.contentsOfDirectory(at: src, includingPropertiesForKeys: properties, options: [])

                for p in paths {
                     if p.hasSuffix(".data"){
                           print("File Path is: \(p)")
                     }
                }

            } catch  {  }
        }

I'm not sure I like the compiling at link time. However, if you're just replacing the element with another you don't need to do that.

All in all I prefer the first one. Simply set scope to {ngModel:"="} and set ng-model="ngModel" where you want it in your template.

Update: I inlined the code snippet and updated it for Angular v1.2. Turns out that isolate scope is still best, especially when not using jQuery. So it boils down to:

• Are you replacing a single element: Just replace it, leave the scope alone, but note that replace is deprecated for v2.0:

  app.directive('myReplacedDirective', function($compile) {
    return {
      restrict: 'E',
      template: '<input class="some">',
      replace: true
    };
  });
  

• Otherwise use this:

  app.directive('myDirectiveWithScope', function() {
    return {
      restrict: 'E',
      scope: {
        ngModel: '=',
      },
      template: '<div class="some"><input ng-model="ngModel"></div>'
    };
  });
  

Dynamic linking (.so) can be much much faster than static linking (.a). Especially when you have a slow network drive. This is since you have all of the code in the .a file which needs to be processed and written out. In addition, a much larger executable file needs to be written out to the disk.

@smaclell asked why reverse iteration was more efficient in in a comment to @sambo99.

Sometimes it's more efficient. Consider you have a list of people, and you want to remove or filter all customers with a credit rating < 1000;

We have the following data

"Bob" 999
"Mary" 999
"Ted" 1000

If we were to iterate forward, we'd soon get into trouble

for( int idx = 0; idx < list.Count ; idx++ )
{
    if( list[idx].Rating < 1000 )
    {
        list.RemoveAt(idx); // whoops!
    }
}

At idx = 0 we remove Bob, which then shifts all remaining elements left. The next time through the loop idx = 1, but list[1] is now Ted instead of Mary. We end up skipping Mary by mistake. We could use a while loop, and we could introduce more variables.

Or, we just reverse iterate:

for (int idx = list.Count-1; idx >= 0; idx--)
{
    if (list[idx].Rating < 1000)
    {
        list.RemoveAt(idx);
    }
}

All the indexes to the left of the removed item stay the same, so you don't skip any items.

The same principle applies if you're given a list of indexes to remove from an array. In order to keep things straight you need to sort the list and then remove the items from highest index to lowest.

Now you can just use Linq and declare what you're doing in a straightforward manner.

list.RemoveAll(o => o.Rating < 1000);

For this case of removing a single item, it's no more efficient iterating forwards or backwards. You could also use Linq for this.

int removeIndex = list.FindIndex(o => o.Name == "Ted");
if( removeIndex != -1 )
{
    list.RemoveAt(removeIndex);
}

If your file contains lines with different lengths and you need to read lines often and you need to read it quickly you can make an index of the file by reading it once, saving position of each new line and then when you need to read a line, you just lookup the position of the line in your index, seek there and then you read the line.

If you add new lines to the file you can just add index of new lines and you don't need to reindex it all. Though if your file changes somewhere in a line you have already indexed then you have to reindex.

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

Actually, using ZSH allows you to use special mapping of environment variables. So you can simply do:

# append
path+=('/home/david/pear/bin')
# or prepend
path=('/home/david/pear/bin' $path)
# export to sub-processes (make it inherited by child processes)
export PATH

For me that's a very neat feature which can be propagated to other variables. Example:

typeset -T LD_LIBRARY_PATH ld_library_path :

For development purpose https://mailtrap.io/ provides you with all the settings that needs to be added in .env file. Eg:

Host:   mailtrap.io
Port:   25 or 465 or 2525
Username:   cb1d1475bc6cce
Password:   7a330479c15f99
Auth:   PLAIN, LOGIN and CRAM-MD5
TLS:    Optional

Otherwise for implementation purpose you can get the smtp credentials to be added in .env file from the mail (like gmail n all)

After addition make sure to restart the server

var test = parseInt($("#testid").val());

If you are looking for full control of Google Analytics's new tracking code, you could use my very own Angular-GA.

It makes ga available through injection, so it's easy to test. It doesn't do any magic, apart from setting the path on every routeChange. You still have to send the pageview like here.

app.run(function ($rootScope, $location, ga) {
    $rootScope.$on('$routeChangeSuccess', function(){
        ga('send', 'pageview');
    });
});

Additionaly there is a directive ga which allows to bind multiple analytics functions to events, like this:

<a href="#" ga="[['set', 'metric1', 10], ['send', 'event', 'player', 'play', video.id]]"></a>

In one line, answer is as below;

[ CASE WHEN COLUMN_NAME = 'VALUE' THEN 'SHOW_THIS' ELSE 'SHOW_OTHER' END as ALIAS ]

for a simple way to get all tables on the server, try this:

SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
INSERT INTO @AllTables (CompleteTableName)
    EXEC sp_msforeachdb 'select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id'
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1

it will return a single column that contains the server+database+schema+table name: sample output:

CompleteTableName
--------------------------------------------
YourServer.YourDatabase1.YourSchema1.YourTable1
YourServer.YourDatabase1.YourSchema1.YourTable2
YourServer.YourDatabase1.YourSchema2.YourTable1
YourServer.YourDatabase1.YourSchema2.YourTable2
YourServer.YourDatabase2.YourSchema1.YourTable1

if you are not on SQL Server 2005 or up, replace the DECLARE @AllTables table with CREATE TABLE #AllTables and then every @AllTables with #AllTables and it will work.

EDIT
here is a version that will allow a search parameter to be used on any part or parts of the server+database+schema+table names:

SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
DECLARE @Search nvarchar(4000)
       ,@SQL   nvarchar(4000)
SET @Search=null --all rows
SET @SQL='select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id WHERE @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name LIKE ''%'+ISNULL(@SEARCH,'')+'%'''

INSERT INTO @AllTables (CompleteTableName)
    EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1

set @Search to NULL for all tables, set it to things like 'dbo.users' or 'users' or '.master.dbo' or even include wildcards like '.master.%.u', etc.

The attributes can be setting directly in swift 3...

    let attributes = NSAttributedString(string: "String", attributes: [NSFontAttributeName : UIFont(name: "AvenirNext-Medium", size: 30)!,
         NSForegroundColorAttributeName : UIColor .white,
         NSTextEffectAttributeName : NSTextEffectLetterpressStyle])

Then use the variable in any class with attributes

I would like to mention one case where you must use std::move() otherwise it will give an error. Case: If the return type of the function differs from the type of the local variable.

class Base { ... };
class Derived : public Base { ... };
...
std::unique_ptr<Base> Foo() {
     std::unique_ptr<Derived> derived(new Derived());
     return std::move(derived); //std::move() must
}

Maybe not so perfect as above ones, but I guess this is what you were looking for.

data[1:1,3:3]    #works with positive integers
data[1:1, -3:-3] #does not work, gives the entire 1st row without the 3rd element
data[i:i,j:j]    #given that i and j are positive integers

Here indexing will work from 1, i.e,

data[1:1,1:1]    #means the top-leftmost element

For everyone asking for code in C#, below is a simplified version of my implementation.

public static void TakeScreenshot(IWebDriver driver, IWebElement element)
{
    try
    {
        string fileName = DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + ".jpg";
        Byte[] byteArray = ((ITakesScreenshot)driver).GetScreenshot().AsByteArray;
        System.Drawing.Bitmap screenshot = new System.Drawing.Bitmap(new System.IO.MemoryStream(byteArray));
        System.Drawing.Rectangle croppedImage = new System.Drawing.Rectangle(element.Location.X, element.Location.Y, element.Size.Width, element.Size.Height);
        screenshot = screenshot.Clone(croppedImage, screenshot.PixelFormat);
        screenshot.Save(String.Format(@"C:\SeleniumScreenshots\" + fileName, System.Drawing.Imaging.ImageFormat.Jpeg));
    }
    catch (Exception e)
    {
        logger.Error(e.StackTrace + ' ' + e.Message);
    }
}

You can use HTTP Toolkit to do exactly this.

It's especially useful if you need to do this quickly, with no code changes: you can open a terminal from HTTP Toolkit, run any Python code from there as normal, and you'll be able to see the full content of every HTTP/HTTPS request immediately.

There's a free version that can do everything you need, and it's 100% open source.

I'm the creator of HTTP Toolkit; I actually built it myself to solve the exact same problem for me a while back! I too was trying to debug a payment integration, but their SDK didn't work, I couldn't tell why, and I needed to know what was actually going on to properly fix it. It's very frustrating, but being able to see the raw traffic really helps.

The below command will work if you want create a new user give him all the access to a specific database(not all databases in your Mysql) on your localhost.

GRANT ALL PRIVILEGES ON test_database.* TO 'user'@'localhost' IDENTIFIED BY 'password';

This will grant all privileges to one database test_database (in your case dbTest) to that user on localhost.

Check what permissions that above command issued to that user by running the below command.

SHOW GRANTS FOR 'user'@'localhost'

Just in case, if you want to limit the user access to only one single table

GRANT ALL ON mydb.table_name TO 'someuser'@'host';

In my situation I needed to answer some questions without Y or N but with text or blank. I found the best way to do this in my situation was to create a shellscript file. In my case I called it autocomplete.sh

I was needing to answer some questions for a doctrine schema exporter so my file looked like this.

-- This is an example only --

php vendor/bin/mysql-workbench-schema-export mysqlworkbenchfile.mwb ./doctrine << EOF
`#Export to Doctrine Annotation Format`                                     1
`#Would you like to change the setup configuration before exporting`        y
`#Log to console`                                                           y
`#Log file`                                                                 testing.log
`#Filename [%entity%.%extension%]`
`#Indentation [4]`
`#Use tabs [no]`
`#Eol delimeter (win, unix) [win]`
`#Backup existing file [yes]`

`#Skip plural name checking [no]`
`#Use logged storage [no]`
`#Sort tables and views [yes]`
`#Export only table categorized []`
`#Enhance many to many detection [yes]`
`#Skip many to many tables [yes]`
`#Bundle namespace []`
`#Entity namespace []`
`#Repository namespace []`
`#Use automatic repository [yes]`
`#Skip column with relation [no]`
`#Related var name format [%name%%related%]`
`#Nullable attribute (auto, always) [auto]`
`#Generated value strategy (auto, identity, sequence, table, none) [auto]`
`#Default cascade (persist, remove, detach, merge, all, refresh, ) [no]`
`#Use annotation prefix [ORM\]`
`#Skip getter and setter [no]`
`#Generate entity serialization [yes]`
`#Generate extendable entity [no]`                                          y
`#Quote identifier strategy (auto, always, none) [auto]`
`#Extends class []`
`#Property typehint [no]`
EOF

The thing I like about this strategy is you can comment what your answers are and using EOF a blank line is just that (the default answer). Turns out by the way this exporter tool has its own JSON counterpart for answering these questions, but I figured that out after I did this =).

to run the script simply be in the directory you want and run 'sh autocomplete.sh' in terminal.

In short by using << EOL & EOF in combination with Return Lines you can answer each question of the prompt as necessary. Each new line is a new answer.

My example just shows how this can be done with comments also using the ` character so you remember what each step is.

Note the other advantage of this method is you can answer with more then just Y or N ... in fact you can answer with blanks!

Hope this helps someone out.

We do it differently. IMHO we do it in an easier way: in master we are working on the next major version.

Each larger feature gets its own branch (derived from master) and will be rebased (+ force pushed) on top of master regularly by the developer. Rebasing only works fine if a single developer works on this feature. If the feature is finished, it will be freshly rebased onto master and then the master fast-forwarded to the latest feature commit.

To avoid the rebasing/forced push one also can merge master changes regularly to the feature branch and if it's finished merge the feature branch into master (normal merge or squash merge). But IMHO this makes the feature branch less clear and makes it much more difficult to reorder/cleanup the commits.

If a new release is coming, we create a side-branch out of master, e.g. release-5 where only bugs get fixed.

At some point I read a reasonably convincing argument on Perlmonks that testing the type of a scalar with ref or reftype is a bad idea. I don't recall who put the idea forward, or the link. Sorry.

The point was that in Perl there are many mechanisms that make it possible to make a given scalar act like just about anything you want. If you tie a filehandle so that it acts like a hash, the testing with reftype will tell you that you have a filehanle. It won't tell you that you need to use it like a hash.

So, the argument went, it is better to use duck typing to find out what a variable is.

Instead of:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;
    if( $type eq 'HASH' ) {
        $result = $var->{foo};
    }
    elsif( $type eq 'ARRAY' ) {
        $result = $var->[3];
    }
    else {
        $result = 'foo';
    }

    return $result;
}

You should do something like this:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;

    eval {
        $result = $var->{foo};
        1; # guarantee a true result if code works.
    }
    or eval { 
        $result = $var->[3];
        1;
    }
    or do {
        $result = 'foo';
    }

    return $result;
}

For the most part I don't actually do this, but in some cases I have. I'm still making my mind up as to when this approach is appropriate. I thought I'd throw the concept out for further discussion. I'd love to see comments.

Update

I realized I should put forward my thoughts on this approach.

This method has the advantage of handling anything you throw at it.

It has the disadvantage of being cumbersome, and somewhat strange. Stumbling upon this in some code would make me issue a big fat 'WTF'.

I like the idea of testing whether a scalar acts like a hash-ref, rather that whether it is a hash ref.

I don't like this implementation.

Consolidating Jason Pratt's and the community wiki answers, with a look at the results of different methods of binding:

Especially note how adding the binding function as a class method works, but the referencing scope is incorrect.

# get a list of a class's method type attributes

        print m[0], m[1]

# externally bind a function as a method of an instance of a class
def ADDMETHOD(c, method, name):
    c.__dict__[name] = types.MethodType(method, c)

    r = 10 # class attribute variable to test bound scope

    def __init__(self):
        pass

Personally, I prefer the external ADDMETHOD function route, as it allows me to dynamically assign new method names within an iterator as well.

def y(self, x):
    pass
d = C()
for i in range(1,5):
    ADDMETHOD(d, y, 'f%d' % i)
print '\nattributes of d:'
listattr(d)
# OUT:
# attributes of d:
# __init__ <bound method C.__init__ of <__main__.C instance at 0x0000000002303508>>
# addmethod <bound method C.addmethod of <__main__.C instance at 0x0000000002303508>>
# f0 <bound method C.f0 of <__main__.C instance at 0x0000000002303508>>
# f1 <bound method ?.y of <__main__.C instance at 0x0000000002303508>>
# f2 <bound method ?.y of <__main__.C instance at 0x0000000002303508>>
# f3 <bound method ?.y of <__main__.C instance at 0x0000000002303508>>
# f4 <bound method ?.y of <__main__.C instance at 0x0000000002303508>>

Ctrl-Alt-X is the keyboard shortcut I use, although that may because I have Resharper installed - otherwise Ctrl W, X.

From the menu: View -> Toolbox.

You can easily view/change key bindings using Tools -> Options Environment->Keyboard. It has a convenient UI where you can enter a word, and it shows you what key bindings include that word, including View.Toolbox.

You might want to browse through the online MSDN documentation on getting started with Visual Studio.

I had this same problem, do this

if [ 'xyz' = 'abc' ]; then
  echo "match"
fi

Notice the whitespace. It is important that you use a whitespace in this case after and before the = sign.

Check out "Other Comparison Operators".

Just disable Instant Run.

Go To File >> Settings >> Build, Execute, Deployment >> Instant Run

Uncheck The Box that says Enable instant run to hot swap code/resource changes on deploy

Re-run the emulator.

1 - You can use the same activity as both dialog and full screen, dynamically:

Call setTheme(android.R.style.Theme_Dialog) before calling setContentView(...) and super.oncreate() in your Activity.

2 - If you don't plan to change the activity theme style you can use

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

This answer will help in case, If you are working with Data Bases then mostly take the help of try-catch block statement, which will help and guide you with your code. Here i am showing you that how to insert some values in Data Base with a Button Click Event.

 private void button2_Click(object sender, EventArgs e)
    {
        System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
        conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" +
    @"Data source= C:\Users\pir fahim shah\Documents\TravelAgency.accdb";

     try
       {
           conn.Open();
           String ticketno=textBox1.Text.ToString();                 
           String Purchaseprice=textBox2.Text.ToString();
           String sellprice=textBox3.Text.ToString();
           String my_querry = "INSERT INTO Table1(TicketNo,Sellprice,Purchaseprice)VALUES('"+ticketno+"','"+sellprice+"','"+Purchaseprice+"')";

            OleDbCommand cmd = new OleDbCommand(my_querry, conn);
            cmd.ExecuteNonQuery();

            MessageBox.Show("Data saved successfuly...!");
          }
         catch (Exception ex)
         {
             MessageBox.Show("Failed due to"+ex.Message);
         }
         finally
         {
             conn.Close();
         }

Use this:

 Array.Resize(ref myArr, myArr.Length + 5);

For extending control functionality like this, I like to use extension methods so that it can be reused easily. Here is a starter extensions file that contains an extension to disable sorting on a datagridview.

To use it, just include it in your project and call like this

myDatagridView.DisableSorting()

In my case, I added this line of code in the DataBindingComplete eventhandler of the DataGridView where I wanted sorting disabled

Imports System.ComponentModel
Imports System.Reflection
Imports System.Runtime.CompilerServices
Imports System.Windows.Forms

Public Module Extensions

<Extension()>
Public Sub DisableSorting(datagrid As DataGridView)
    For index = 0 To datagrid.Columns.Count - 1
        datagrid.Columns(index).SortMode = DataGridViewColumnSortMode.NotSortable
    Next
End Sub


End Module

angularjs .post() defaults the Content-type header to application/json. You are overriding this to pass form-encoded data, however you are not changing your data value to pass an appropriate query string, so PHP is not populating $_POST as you expect.

My suggestion would be to just use the default angularjs setting of application/json as header, read the raw input in PHP, and then deserialize the JSON.

That can be achieved in PHP like this:

$postdata = file_get_contents("php://input");
$request = json_decode($postdata);
$email = $request->email;
$pass = $request->password;

Alternately, if you are heavily relying on $_POST functionality, you can form a query string like [email protected]&password=somepassword and send that as data. Make sure that this query string is URL encoded. If manually built (as opposed to using something like jQuery.serialize()), Javascript's encodeURIComponent() should do the trick for you.

So it looks like root.iconbitmap() only supports a fixed directory.
sys.argv[0] returns the directory that the file was read from so a simple code would work to create a fixed directory.

import sys
def get_dir(src):
    dir = sys.argv[0]
    dir = dir.split('/')
    dir.pop(-1)
    dir = '/'.join(dir)
    dir = dir+'/'+src
    return dir

This is the output

>>> get_dir('test.txt')
'C:/Users/Josua/Desktop/test.txt'

EDIT:
The only issue is that this method dosn't work on linux

josua@raspberrypi:~ $ python
Python 2.7.9 (default, Sep 17 2016, 20:26:04) [GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys

Don't forget that you can also redirect constructors to other constructors at the same level of inheritance:

public Bar(int i, int j) : this(i) { ... }
                            ^^^^^

If you want to do something more complicated with your text you could create your own filter and do some magic before returning the html. With a templatag file looking like this:

from django import template
from django.utils.safestring import mark_safe

register = template.Library()

@register.filter
def do_something(title, content):

    something = '<h1>%s</h1><p>%s</p>' % (title, content)
    return mark_safe(something)

Then you could add this in your template file

<body>
...
    {{ title|do_something:content }}
...
</body>

And this would give you a nice outcome.

In case, someone looking for lower version -

For SQL Server 2000:

sp_changeobjectowner @objname = 'dbo.Employess' , @newowner ='exe'

I got the way to redirect the out put to console as well as to a text file as well simultaneously:

te = open('log.txt','w')  # File where you need to keep the logs

class Unbuffered:

   def __init__(self, stream):

       self.stream = stream

   def write(self, data):

       self.stream.write(data)
       self.stream.flush()
       te.write(data)    # Write the data of stdout here to a text file as well



sys.stdout=Unbuffered(sys.stdout)

The (un)safe way to do this - if you are ok with not using option explicit - is...

Not TypeName(myObj) = "Empty"

This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...

Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ true, the object exists - TypeName is Object

'Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ false, the object has not been declared

This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.
