try

<select onchange="location=this.value">_x000D_
    <option value="unit_01.htm">Unit 1</option>_x000D_
    <option value="#5.2" selected >Bookmark 2</option>_x000D_
</select>

And the Purescript answer, for people using Halogen:

import CSS (display, displayNone)
import Halogen.HTML as HH
import Halogen.HTML.CSS as CSS

render state = 
  HH.div [ CSS.style $ display displayNone ] [ HH.text "Hi there!" ]

If you "inspect element", you'll see something like:

<div style="display: none">Hi there!</div>

but nothing will actually display on your screen, as expected.

final ListView lv = (ListView) findViewById(R.id.ListView01);

lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
        String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));

      }                 
});

I hope this fixes your problem.

Label without an onclick will behave as you would expect. It changes the input. What you relly want is to execute selectAll() when you click on a label, right? Then only add select all to the label onclick. Or wrap the input into the the label and assign onclick only for the label

<label for="check_all_1" onclick="selectAll(document.wizard_form, this);">
  <input type="checkbox" id="check_all_1" name="check_all_1" title="Select All">
  Select All
</label>

try following solution

HTML:

<div id="variant">
<label><input type="radio" name="toggle" class="radio" value="19,99€"><span>A</span></label>
<label><input type="radio" name="toggle" class="radio" value="<<<"><span>B</span></label>
<label><input type="radio" name="toggle" class="radio" value="xxx"><span>C</span></label>
<p id="price"></p>

JS:

$(document).ready(function () {
       $('.radio').click(function () {
           document.getElementById('price').innerHTML = $(this).val();
       });

   });

Based on the answer that @Mukund Kumar gave here's a version that passes the event argument to the anonymous function:

<a href="#" onClick="(function(e){
    console.log(e);
    alert('Hey i am calling');
    return false;
})(arguments[0]);return false;">click here</a>

This will do the trick:

  public void itemClicked(View v) {
    if (((CheckBox) v).isChecked()) {
        Toast.makeText(MyAndroidAppActivity.this,
           "Checked", Toast.LENGTH_LONG).show();
    }
  }

Window.postMessage()

This method safely enables cross-origin communication.

And if you have access to parent page code then any parent method can be called as well as any data can be passed directly from Iframe. Here is a small example:

Parent page:

if (window.addEventListener) {
    window.addEventListener("message", onMessage, false);        
} 
else if (window.attachEvent) {
    window.attachEvent("onmessage", onMessage, false);
}

function onMessage(event) {
    // Check sender origin to be trusted
    if (event.origin !== "http://example.com") return;

    var data = event.data;

    if (typeof(window[data.func]) == "function") {
        window[data.func].call(null, data.message);
    }
}

// Function to be called from iframe
function parentFunc(message) {
    alert(message);
}

Iframe code:

window.parent.postMessage({
    'func': 'parentFunc',
    'message': 'Message text from iframe.'
}, "*");
// Use target origin instead of *

UPDATES:

Security note:

Always provide a specific targetOrigin, NOT *, if you know where the other window's document should be located. Failing to provide a specific target discloses the data you send to any interested malicious site (comment by ZalemCitizen).

As the API's have radically changed, It wouldn't surprise me if you were to create an OnClickListener for each item. It isn't that much of a hassle though. In your implementation of RecyclerView.Adapter<MyViewHolder>, you should have:

private final OnClickListener mOnClickListener = new MyOnClickListener();

@Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.myview, parent, false);
    view.setOnClickListener(mOnClickListener);
    return new MyViewHolder(view);
}

The onClick method:

@Override
public void onClick(final View view) {
    int itemPosition = mRecyclerView.getChildLayoutPosition(view);
    String item = mList.get(itemPosition);
    Toast.makeText(mContext, item, Toast.LENGTH_LONG).show();
}

This is a press down button example I've made:

<div>
    <form id="forminput" action="action" method="POST">
       ...
    </form>
    <div style="right: 0px;bottom: 0px;position: fixed;" class="thumbnail">
        <div class="image">
            <a onclick="document.getElementById('forminput').submit();">
                <img src="images/button.png" alt="Some awesome text">
            </a>
        </div>
    </div>
</div>

the CSS file:

.thumbnail {
    width: 128px;
    height: 128px;
}

.image {
    width: 100%;
    height: 100%;    
}

.image img {
    -webkit-transition: all .25s ease; /* Safari and Chrome */
    -moz-transition: all .25s ease; /* Firefox */
    -ms-transition: all .25s ease; /* IE 9 */
    -o-transition: all .25s ease; /* Opera */
    transition: all .25s ease;
    max-width: 100%;
    max-height: 100%;
}

.image:hover img {
    -webkit-transform:scale(1.05); /* Safari and Chrome */
    -moz-transform:scale(1.05); /* Firefox */
    -ms-transform:scale(1.05); /* IE 9 */
    -o-transform:scale(1.05); /* Opera */
     transform:scale(1.05);
}

.image:active img {
    -webkit-transform:scale(.95); /* Safari and Chrome */
    -moz-transform:scale(.95); /* Firefox */
    -ms-transform:scale(.95); /* IE 9 */
    -o-transform:scale(.95); /* Opera */
     transform:scale(.95);
}

Enjoy it!

I decide to publish my example that I used in my case. I tried to replace content in div using a script. My problem was that Chrome did not recognized / did not run that script.

In more detail What I wanted to do: To click on a link, and that link to "read" an external html file, that it will be loaded in a div section.

• I found out that by placing the script before the DIV with ID that was called, the script did not work.
• If the script was in another DIV, also it does not work

• The script must be coded using document.addEventListener('DOMContentLoaded', function() as it was told

      <body>
      <a id=id_page href ="#loving"   onclick="load_services()"> loving   </a>
  
          <script>
                  // This script MUST BE under the "ID" that is calling
                  // Do not transfer it to a differ DIV than the caller "ID"
                  document.getElementById("id_page").addEventListener("click", function(){
                  document.getElementById("mainbody").innerHTML = '<object data="Services.html" class="loving_css_edit"; ></object>'; });
              </script>
      </body>
  
    <div id="mainbody" class="main_body">
          "here is loaded the external html file when the loving link will 
           be  clicked. "
    </div>
  

Why do you need to attach it to the HTML? Just bind the function with hover

$("div.system_box").hover(function(){ mousin }, 
                          function() { mouseout });

If you do insist to have JS references inside the html, which is usualy a bad idea you can use:

onmouseover="yourJavaScriptCode()"

after topic edit:

<div class="system_box" data-target="sms_box">

...

$("div.system_box").click(function(){ slideonlyone($(this).attr("data-target")); });

There are lots of ways. And this should work too in all browsers and you don't have to use document.getElementById anymore since you're passing the element itself to the function.

<input type="button" value="Open Curtain" onclick="return change(this);" />

<script type="text/javascript">
function change( el )
{
    if ( el.value === "Open Curtain" )
        el.value = "Close Curtain";
    else
        el.value = "Open Curtain";
}
</script>

No Problem You can use onClick() function easily without using any other interference of language,

<?php
echo '<br><Button onclick="document.getElementById(';?>'modal-wrapper2'<?php echo ').style.display=';?>'block'<?php echo '" name="comment" style="width:100px; color: white;background-color: black;border-radius: 10px; padding: 4px;">Show</button>';
?>

Knockout's documentation also mentions a much cleaner way of passing extra parameters to functions bound using an on-click binding using function.bind like this:

<button data-bind="click: myFunction.bind($data, 'param1', 'param2')">
    Click me
</button>

You will have to do this via AJAX. I HEAVILY reccommend you use jQuery to make this easier for you....

$("#idOfElement").on('click', function(){

    $.ajax({
       url: 'pathToPhpFile.php',
       dataType: 'json',
       success: function(data){
            //data returned from php
       }
    });
)};

http://api.jquery.com/jQuery.ajax/

The question title says "How can I simulate an anchor click in jQuery?". Well, you can use the "trigger" or "triggerHandler" methods, like so:

<script type="text/javascript" src="path/to/jquery.js"></script>
<script type="text/javascript" src="path/to/thickbox.js"></script>
<script type="text/javascript">
$(function() {
    $('#btn').click(function() {
        $('#thickboxId').triggerHandler('click');
    })
})
</script>
...
<input id="btn" type="button" value="Click me">
<a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a>

Not tested, this actual script, but I've used trigger et al before, and they worked a'ight.

UPDATE
triggerHandler doesn't actually do what the OP wants. I think 1421968 provides the best answer to this question.

Try this

$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
    alert('123');
});

$('#ancherComplaint').click(function (event) {
    alert($(this).attr("id"));
    event.stopPropagation()
})

DEMO

You should use onclick method because the function run once when the page is loaded and no button will be clicked then

So you have to add an even which run every time the user press any key to add the changes to the div background

So the function should be something like this

htmlelement.onclick() = function(){
    //Do the changes 
}

So your code has to look something like this :

var box = document.getElementById("box");
var yes = document.getElementById("yes");
var no = document.getElementById("no");

yes.onclick = function(){
    box.style.backgroundColor = "red";
}

no.onclick = function(){
    box.style.backgroundColor = "green";
}

This is meaning that when #yes button is clicked the color of the div is red and when the #no button is clicked the background is green

Here is a Jsfiddle

better to use touchstart event with .on() jQuery method:

$(window).load(function() { // better to use $(document).ready(function(){
    $('.List li').on('click touchstart', function() {
        $('.Div').slideDown('500');
    });
});

And i don't understand why you are using $(window).load() method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready() method which does not wait for each element on the page to be loaded first.

Try like

<script>
function Data(string)
{      
  $('.filter').removeClass('active');
  $(this).parent('.filter').addClass('active') ;
} 
</script>

For the class selector you need to use . before the classname.And you need to add the class for the parent. Bec you are clicking on anchor tag not the filter.

It sounds like your printMousePos function should:

1. Get the X and Y coordinates of the mouse
2. Add those values to the HTML

Currently, it does this:

1. Creates (undefined) variables for the X and Y coordinates of the mouse
2. Attaches a function to the "mousemove" event (which will set those variables to the mouse coordinates when triggered by a mouse move)
3. Adds the current values of your variables to the HTML

See the problem? Your variables are never getting set, because as soon as you add your function to the "mousemove" event you print them.

It seems like you probably don't need that mousemove event at all; I would try something like this:

function printMousePos(e) {
    var cursorX = e.pageX;
    var cursorY = e.pageY;
    document.getElementById('test').innerHTML = "x: " + cursorX + ", y: " + cursorY;
}

Perhaps setOnClickListener(null) ?

On the order of DOM events: CAPTURING vs BUBBLING

There are two stages for how events propagate. These are called "capturing" and "bubbling".

               | |                                   / \
---------------| |-----------------   ---------------| |-----------------
| element1     | |                |   | element1     | |                |
|   -----------| |-----------     |   |   -----------| |-----------     |
|   |element2  \ /          |     |   |   |element2  | |          |     |
|   -------------------------     |   |   -------------------------     |
|        Event CAPTURING          |   |        Event BUBBLING           |
-----------------------------------   -----------------------------------

The capturing stage happen first, and are then followed by the bubbling stage. When you register an event using the regular DOM api, the events will be part of the bubbling stage by default, but this can be specified upon event creation

// CAPTURING event
button.addEventListener('click', handleClick, true)

// BUBBLING events
button.addEventListener('click', handleClick, false)
button.addEventListener('click', handleClick)

In React, bubbling events are also what you use by default.

// handleClick is a BUBBLING (synthetic) event
<button onClick={handleClick}></button>

// handleClick is a CAPTURING (synthetic) event
<button onClickCapture={handleClick}></button>

Let's take a look inside our handleClick callback (React):

function handleClick(e) {
  // This will prevent any synthetic events from firing after this one
  e.stopPropagation()
}

function handleClick(e) {
  // This will set e.defaultPrevented to true
  // (for all synthetic events firing after this one)
  e.preventDefault()  
}

An alternative that I haven't seen mentioned here

If you call e.preventDefault() in all of your events, you can check if an event has already been handled, and prevent it from being handled again:

handleEvent(e) {
  if (e.defaultPrevented) return  // Exits here if event has been handled
  e.preventDefault()

  // Perform whatever you need to here.
}

For the difference between synthetic events and native events, see the React documentation: https://reactjs.org/docs/events.html

You are supposed to be able to specify a domain that is safe for scripting. the api document mentions "As an extra security measure, you should also include the origin parameter to the URL" http://code.google.com/apis/youtube/iframe_api_reference.html src="http://www.youtube.com/embed/J---aiyznGQ?enablejsapi=1&origin=mydomain.com" would be the src of your iframe.

however it is not very well documented. I am trying something similar right now.

Try:

public void onclick(View v){
            ImageView activity= (ImageView) findViewById(R.id.imageview1);
        button1.setImageResource(R.drawable.buttonpressed);}

If your onclick function returns false the default browser behaviour is cancelled. As such:

<a href='http://www.google.com' onclick='return check()'>check</a>

<script type='text/javascript'>

function check()
{
    return false;
}

</script>

Either way, whether google does it or not isn't of much importance. It's cleaner to bind your onclick functions within javascript - this way you separate your HTML from other code.

Came up with a quick and dirty fix to this. Just used <select onchange='this.options[this.selectedIndex].onclick();> <option onclick='alert("hello world")' ></option> </select>

Hope this helps

There is another solution you can try by using only the css here is the answer i posted in another post: jQuery Accordion change font awesome icon class on click

Asp.net CheckBox is not support method OnClientClick.
If you want to add some javascript event to asp:CheckBox you have to add related attributes on "Pre_Render" or on "Page_Load" events in server code:

C#:

    private void Page_Load(object sender, EventArgs e)
    {
        SomeCheckBoxId.Attributes["onclick"] = "MyJavaScriptMethod(this);";
    }

Note: Ensure you don't set AutoEventWireup="false" in page header.

VB:

    Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
        SomeCheckBoxId.Attributes("onclick") = "MyJavaScriptMethod(this);"
    End Sub

I think you need to use one of those methods in order to be able to intercept the event before it gets sent to the appropriate components:

Activity.dispatchTouchEvent(MotionEvent) - This allows your Activity to intercept all touch events before they are dispatched to the window.

ViewGroup.onInterceptTouchEvent(MotionEvent) - This allows a ViewGroup to watch events as they are dispatched to child Views.

ViewParent.requestDisallowInterceptTouchEvent(boolean) - Call this upon a parent View to indicate that it should not intercept touch events with onInterceptTouchEvent(MotionEvent).

More information here.

Hope that helps.

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="https://www.yahoo.com/" selected>Option1</option>
    <option value="https://www.google.co.in/">Option2</option>
    <option value="https://www.gmail.com/">Option3</option>

</select>

And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){
        location.href=document.getElementById("selectbox").value;
    }       
</script>

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val(); 
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
    })
})

Instead use window.open():

The syntax is:

window.open(strUrl, strWindowName[, strWindowFeatures]);

Your code should have:

window.open('Prosjektplan.pdf');

Your code should be:

<p class="downloadBoks"
   onclick="window.open('Prosjektplan.pdf')">Prosjektbeskrivelse</p>

Use ng-click in place of onclick. and its as simple as that:

<a href="www.mysite.com" ng-click="return theFunction();">Item</a>

<script type="text/javascript">
function theFunction () {
    // return true or false, depending on whether you want to allow 
    // the`href` property to follow through or not
 }
</script>

No need to worry for incrementing/decrementing numbers using Javascript. Now HTML itself provides an easy way for it.

<input type="number" value="50">

It is that simple.The problem is that it works fine only in some browsers.Mozilla has not yet supported this feature.

Another alternative solution to toggle checkbox value:

<div id="parent">
    <img src="" class="avatar" />
    <input type="checkbox" name="" />
</div>


$("img.avatar").click(function(){

    var op = !$(this).parent().find(':checkbox').attr('checked');
    $(this).parent().find(':checkbox').attr('checked', op);

});

Modify the_script.php like this.

<script>
the_function() {
    alert("You win");
}
</script>

jQuery .on method is used to bind events even without the presence of element on page load. Here is the link It is used in this way:

 $("#dataTable tbody tr").on("click", function(event){
    alert($(this).text());
 });

Before jquery 1.7, .live() method was used, but it is deprecated now.

Remove 'javascript:' from your code and it should work.

Do you happen to use FireFox? I have learned from someone else that FireFox no longer accepts the 'javascript:' string. However, for the life of me, I cannot find the original source (though I believe it was somewhere in FF update notes).

You can do it by using window_handles and switch_to_window method.

Before clicking the link first store the window handle as

window_before = driver.window_handles[0]

after clicking the link store the window handle of newly opened window as

window_after = driver.window_handles[1]

then execute the switch to window method to move to newly opened window

driver.switch_to_window(window_after)

and similarly you can switch between old and new window. Following is the code example

import unittest
from selenium import webdriver

class GoogleOrgSearch(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Firefox()

    def test_google_search_page(self):
        driver = self.driver
        driver.get("http://www.cdot.in")
        window_before = driver.window_handles[0]
        print window_before
        driver.find_element_by_xpath("//a[@href='http://www.cdot.in/home.htm']").click()
        window_after = driver.window_handles[1]
        driver.switch_to_window(window_after)
        print window_after
        driver.find_element_by_link_text("ATM").click()
        driver.switch_to_window(window_before)

    def tearDown(self):
        self.driver.close()

if __name__ == "__main__":
    unittest.main()

You also can use:

element.addEventListener("click", function(){
    // call execute function here...
}, false);

Shortest Yet!

<button onclick="history.go(-1);">Go back</button>

http://jsfiddle.net/qXrbx/

I prefer the .go(-number) method as then, for 1 or many 'backs' there's only 1 method to use/remember/update/search for, etc.

Also, using a tag for a back button seems more appropriate than tags with names and types...

Using jquery, try this. if your button id is say id= clickme

$("clickme").on('çlick', function(){

$(this).css('background-color', 'grey'); .......

I just needed a simple testing button for react.js. Here is what I did and it worked.

function Testing(){
 var f=function testing(){
         console.log("Testing Mode activated");
         UserData.authenticated=true;
         UserData.userId='123';
       };
 console.log("Testing Mode");

 return (<div><button onClick={f}>testing</button></div>);
}

All this might not help say when you use rails remote form button to simulate click to. I tried to port nice event simulation from prototype here: my snippets. Just did it and it works for me.

Are you sure you only display your page on webkit? Here is the code,passed on safari. The image (id='img') will rotate after button click.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Ok, after the information that your Activity extends ListActivity here's a way to implement OnItemClickListener:

public class newListView extends ListView {

    public newListView(Context context) {
        super(context);
    }

    @Override
    public void setOnItemClickListener(
            android.widget.AdapterView.OnItemClickListener listener) {
        super.setOnItemClickListener(listener);
        //do something when item is clicked

    }

}

The question has been answered, but for your future coding reference you might like to consider this.

In your HTML, add the name as an attribute to the button and remove the onclick reference.

<button id="button" data-name="Mathew" type="button">click</button>

In your JavaScript, grab the button using its ID, assign the function to the button's click event, and use the function to display the button's data-name attribute.

var button = document.getElementById('button');

button.onclick = myfunction;

function myfunction() {
  var name = this.getAttribute('data-name');
  alert(name);
}

DEMO

onclick is basically an addEventListener that specifically performs a function when the element is clicked. So, useful when you have a button that does simple operations, like a calculator button. addEventlistener can be used for a multitude of things like performing an operation when DOM or all content is loaded, akin to window.onload but with more control.

Note, You can actually use more than one event with inline, or at least by using onclick by seperating each function with a semi-colon, like this....

I wouldn't write a function with inline, as you could potentially have problems later and it would be messy imo. Just use it to call functions already done in your script file.

Which one you use I suppose would depend on what you want. addEventListener for complex operations and onclick for simple. I've seen some projects not attach a specific one to elements and would instead implement a more global eventlistener that would determine if a tap was on a button and perform certain tasks depending on what was pressed. Imo that could potentially lead to problems I'd think, and albeit small, probably, a resource waste if that eventlistener had to handle each and every click

Never use .onclick(), or similar attributes from a userscript! (It's also poor practice in a regular web page).

The reason is that userscripts operate in a sandbox ("isolated world"), and onclick operates in the target-page scope and cannot see any functions your script creates.

Always use addEventListener()^Doc (or an equivalent library function, like jQuery .on()).

So instead of code like:

something.outerHTML += '<input onclick="resetEmotes()" id="btnsave" ...>'

You would use:

something.outerHTML += '<input id="btnsave" ...>'

document.getElementById ("btnsave").addEventListener ("click", resetEmotes, false);

For the loop, you can't pass data to an event listener like that See the doc. Plus every time you change innerHTML like that, you destroy the previous event listeners!

Without refactoring your code much, you can pass data with data attributes. So use code like this:

for (i = 0; i < EmoteURLLines.length; i++) {
    if (checkIMG (EmoteURLLines[i])) {
        localStorage.setItem ("nameEmotes", JSON.stringify (EmoteNameLines));
        localStorage.setItem ("urlEmotes", JSON.stringify (EmoteURLLines));
        localStorage.setItem ("usageEmotes", JSON.stringify (EmoteUsageLines));
        if (i == 0) {
            console.log (resetSlot ());
        }
        emoteTab[2].innerHTML  += '<span style="cursor:pointer;" id="' 
                                + EmoteNameLines[i] 
                                + '" data-usage="' + EmoteUsageLines[i] + '">'
                                + '<img src="' + EmoteURLLines[i] + '" /></span>'
                                ;
    } else {
        alert ("The maximum emote (" + EmoteNameLines[i] + ") size is (36x36)");
    }
}
//-- Only add events when innerHTML overwrites are done.
var targetSpans = emoteTab[2].querySelectorAll ("span[data-usage]");
for (var J in targetSpans) {
    targetSpans[J].addEventListener ("click", appendEmote, false);
}

Where appendEmote is like:

function appendEmote (zEvent) {
    //-- this and the parameter are special in event handlers.  see the linked doc.
    var emoteUsage  = this.getAttribute ("data-usage");
    shoutdata.value += emoteUsage;
}

WARNINGS:

• Your code reuses the same id for several elements. Don't do this, it's invalid. A given ID should occur only once per page.
• Every time you use .outerHTML or .innerHTML, you trash any event handlers on the affected nodes. If you use this method beware of that fact.

My case is similar but this is occasion when you have few foobar-s, and you want to close only one - per one click:

Find parent case

$(".foobar-close-button-class").on("click", function () {
    $(this).parents('.foobar').fadeOut( 100 );
    // 'this' - means that you finding some parent class from '.foobar-close-button-class'
    // '.parents' -means that you finding parent class with name '.foobar'
});

Find child case

$(".foobar-close-button-class").on("click", function () {
    $(this).child('.foobar-close-button-child-class').fadeOut( 100 );
    // 'this' - means that you finding some child class from '.foobar-close-button-class'
    // '.child' -means that you finding child class with name '.foobar-close-button-child-class'
});

<script>var myVar = 15;</script>
<input id="EditBanner" type="button" value="Edit Image" onclick="EditBanner(myVar);"/>

Try using this : iframeTracker jQuery Plugin, like that :

jQuery(document).ready(function($){
    $('.iframe_wrap iframe').iframeTracker({
        blurCallback: function(){
            // Do something when iframe is clicked (like firing an XHR request)
        }
    });
});

From this article on web.archive.org :

The trick is to use the OnClientClick and UseSubmitBehavior properties of the button control. There are other methods, involving code on the server side to add attributes, but I think the simplicity of doing it this way is much more attractive:

<asp:Button runat="server" ID="BtnSubmit"  OnClientClick="this.disabled = true; this.value = 'Submitting...';"   UseSubmitBehavior="false"  OnClick="BtnSubmit_Click"  Text="Submit Me!" />

OnClientClick allows you to add client side OnClick script. In this case, the JavaScript will disable the button element and change its text value to a progress message. When the postback completes, the newly rendered page will revert the button back its initial state without any additional work.

The one pitfall that comes with disabling a submit button on the client side is that it will cancel the browser’s submit, and thus the postback. Setting the UseSubmitBehavior property to false tells .NET to inject the necessary client script to fire the postback anyway, instead of relying on the browser’s form submission behavior. In this case, the code it injects would be:

__doPostBack('BtnSubmit','')

This is added to the end of our OnClientClick code, giving us this rendered HTML:

<input type="button" name="BtnSubmit"  onclick="this.disabled = true; this.value ='Submitting...';__doPostBack('BtnSubmit','')"  value="Submit Me!" id="BtnSubmit" />

This gives a nice button disable effect and processing text, while the postback completes.

I have the below code for mouse hover and mouse click and it works:

//For Mouse Hover
.thumbnail:hover span{ /*CSS for enlarged image*/
    visibility: visible;
    text-align:center;
    vertical-align:middle;
    height: 70%;
    width: 80%;
    top:auto;
    left: 10%;
}

and this code hides the image when you click on it:

.thumbnail:active span {
    visibility: hidden;
}

In JavaScript functions are objects.

document.getElementById('foo').onclick = function(){
    prompt('Hello world');
}

To make your life easier and avoid the Anonymous Class in setOnClicklistener (), implement a View.OnClicklistener Interface as below:

public class YourClass extends CommonActivity implements View.OnClickListener, ...

this avoids:

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        yourMethod(v);
    }
});

and goes directly to:

@Override
public void onClick(View v) {
  switch (v.getId()) {
    case R.id.your_view:
      yourMethod();
      break;
  }
}

in textView

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Text"
    android:onClick="onClick"
    android:clickable="true"

You must also implement View.OnClickListener and in On Click method can use intent

    Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
           intent.setData(Uri.parse("https://youraddress.com"));    
            startActivity(intent);

I tested this solution works fine.

The selector ".nr:first" is specifically looking for the first, and only the first, element having class "nr" within the selected table element. If you instead call .find(".nr") you will get all of the elements within the table having class "nr". Once you have all of those elements, you could use the .each method to iterate over them. For example:

$(".use-address").click(function() {
    $("#choose-address-table").find(".nr").each(function(i, nrElt) {
        var id = nrElt.text();
        $("#resultas").append("<p>" + id + "</p>"); // Testing: append the contents of the td to a div
    });
});

However, that would get you all of the td.nr elements in the table, not just the one in the row that was clicked. To further limit your selection to the row containing the clicked button, use the .closest method, like so:

$(".use-address").click(function() {
    $(this).closest("tr").find(".nr").each(function(i, nrElt) {
        var id = nrElt.text();
        $("#resultas").append("<p>" + id + "</p>"); // Testing: append the contents of the td to a div
    });
});

You can overlay a big, semi-transparent <div> that takes all the clicks. Just append a new <div> to <body> with this style:

.overlay {
    background-color: rgba(1, 1, 1, 0.7);
    bottom: 0;
    left: 0;
    position: fixed;
    right: 0;
    top: 0;
}

You can define a a click function and then set the onclick attribute for the element.

function imageClick(url) {
    window.location = url;
}

<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" onclick="imageClick('../images/bottle.html')" />

This approach lets you get rid of the surrounding <a> element. If you want to keep it, then define the onclick attribute on <a> instead of on <img>.

You can create a single function that calls both of those, and then use it in the event.

function myFunction(){
    pay();
    cls();
}

And then, for the button:

<input id="btn" type="button" value="click" onclick="myFunction();"/>

Everythings works well. You can't use divtag.onclick, becease "onclick" attribute doesn't exist. You need first create this attribute by using .setAttribute(). Look on this http://reference.sitepoint.com/javascript/Element/setAttribute . You should read documentations first before you start giving "-".

Since the question was asking how to do this with JS I'm providing a vanilla JS implementation.

var element = document.querySelector(".your-element-class-goes-here");
// it's a good idea to check whether the element exists
if (element != null && element != undefined) {
  element.disabled = "disabled";
}

 cell1.innerHTML="<?php echo $customerDESC; ?>";
 cell2.innerHTML="<?php echo $comm; ?>";
 cell3.innerHTML="<?php echo $expressFEE; ?>";
 cell4.innerHTML="<?php echo $totao_unit_price; ?>";

it is working like a charm, the javascript is inside a php while loop

On mobile iOS the click event does not bubble to the document body and thus cannot be used with .live() events. If you have to use a non native click-able element like a div or section is to use cursor: pointer; in your css for the non-hover on the element in question. If that is ugly you could look into delegate().

JSX will evaluate JavaScript expressions in curly braces

In this case, this.props.removeTaskFunction(todo) is invoked and the return value is assigned to onClick

What you have to provide for onClick is a function. To do this, you can wrap the value in an anonymous function.

export const samepleComponent = ({todoTasks, removeTaskFunction}) => {
    const taskNodes = todoTasks.map(todo => (
                <div>
                    {todo.task}
                    <button type="submit" onClick={() => removeTaskFunction(todo)}>Submit</button>
                </div>
            );
    return (
        <div className="todo-task-list">
            {taskNodes}
        </div>
        );
    }
});

Try like this...

<script>
function getPaging(str) {
  $("#loading-content").load("dataSearch.php?"+str, hideLoader);
}
</script>

<li onclick="getPaging(this.id)" id="1">1</li>
<li onclick="getPaging(this.id)" id="2">2</li>

or unobtrusively

$(function() {
  $("li").on("click",function() {
    showLoader();
    $("#loading-content").load("dataSearch.php?"+this.id, hideLoader);
  });
});

using just

<li id="1">1</li>
<li id="2">2</li>

As another cheap alternative on somewhat static canvas, using an overlaying img element with a usemap definition is quick and dirty. Works especially well on polygon based canvas elements like a pie chart.

I think your error was in calling the function.

In your HTML code, onclick is calling the image() function. However, in your script the function is named imgWindow(). Try changing the onclick to imgWindow().

I don't do much JavaScript so if I have missed something, please let me know.

Good Luck!

Static, strongly-typed programming has always felt very natural to me, so at first I resisted learning JavaScript (not to mention HTML and CSS) when I had to build web-based front-ends for my applications. I would do anything to work around this like redirecting to a page just to perform and action on the OnLoad event, as long as I could code pure C#.

You will find however that if you are going to be working with websites, you must have an open mind and start thinking more web-oriented (that is, don't try to do client-side things on the server and vice-versa). I love ASP.NET webforms and still use it (as well as MVC), but I will say that by trying to make things simpler and hiding the separation of client and server it can confuse newcomers and actually end up making things more difficult at times.

My advice is to learn some basic JavaScript (how to register events, retrieve DOM objects, manipulate CSS, etc.) and you will find web programming much more enjoyable (not to mention easier). A lot of people mentioned different Ajax libraries, but I didn't see any actual Ajax examples, so here it goes. (If you are not familiar with Ajax, all it is, is making an asynchronous HTTP request to refresh content (or perhaps perform a server-side action in your scenario) without reloading the entire page or doing a full postback.

Client-Side:

<script type="text/javascript">
var xmlhttp = new XMLHttpRequest(); // Create object that will make the request
xmlhttp.open("GET", "http://example.org/api/service", "true"); // configure object (method, URL, async)
xmlhttp.send(); // Send request

xmlhttp.onstatereadychange = function() { // Register a function to run when the state changes, if the request has finished and the stats code is 200 (OK). Write result to <p>
    if (xmlhttp.readyState == 4 && xmlhttp.statsCode == 200) {
          document.getElementById("resultText").innerHTML = xmlhttp.responseText;
    }
};
</script>

That's it. Although the name can be misleading the result can be in plain text or JSON as well, you are not limited to XML. jQuery provides an even simpler interface for making Ajax calls (among simplifying other JavaScript tasks).

The request can be an HTTP-POST or HTTP-GET and does not have to be to a webpage, but you can post to any service that listens for HTTP requests such as a RESTful API. The ASP.NET MVC 4 Web API makes setting up the server-side web service to handle the request a breeze as well. But many people do not know that you can also add API controllers to web forms project and use them to handle Ajax calls like this.

Server-Side:

public class DataController : ApiController
{
    public HttpResponseMessage<string[]> Get()
    {
        HttpResponseMessage<string[]> response = new HttpResponseMessage<string[]>(
            Repository.Get(true),
            new MediaTypeHeaderValue("application/json")
        );

        return response;
    }
}

Global.asax

Then just register the HTTP route in your Global.asax file, so ASP.NET will know how to direct the request.

void Application_Start(object sender, EventArgs e)
{
    RouteTable.Routes.MapHttpRoute("Service", "api/{controller}/{id}");
}

With AJAX and Controllers, you can post back to the server at any time asynchronously to perform any server side operation. This one-two punch provides both the flexibility of JavaScript and the power the C# / ASP.NET, giving the people visiting your site a better overall experience. Without sacrificing anything, you get the best of both worlds.

More on gdoron's answer, it can also be done this way:

$(window).on("click", "#filter", function() {
    alert('clicked!');
});

without the need to place them all into $(function(){...})

iframe doesn't have onclick event but we can implement this by using iframe's onload event and javascript like this...

function iframeclick() {
document.getElementById("theiframe").contentWindow.document.body.onclick = function() {
        document.getElementById("theiframe").contentWindow.location.reload();
    }
}


<iframe id="theiframe" src="youriframe.html" style="width: 100px; height: 100px;" onload="iframeclick()"></iframe>

I hope it will helpful to you....

Try adding $(document).ready(function(){ to the beginning of your script, and then });. Also, does the div have the id in it properly, i.e., as an id, not a class, etc.?

As @Richard pointed out above, the onClick needs to have a capital 'C'.

$('#stop').click(function() {
     $('next').attr('onClick','stopMoving()');
}

<script type="text/javascript">
                    $(document).ready(function(e) {
                        $(".mqimg").mouseover(function()
                        {
                            $("#imgprev").animate({height: "250px",width: "70%",left: "15%"},100).html("<img src='"+$(this).attr('src')+"' width='100%' height='100%' />"); 
                        })
                        $(".mqimg").mouseout(function()
                        {
                            $("#imgprev").animate({height: "0px",width: "0%",left: "50%"},100);
                        })
                    });
                    </script>
                    <style>
                    .mqimg{ cursor:pointer;}
                    </style>
                    <div style="position:relative; width:100%; height:1px; text-align:center;">`enter code here`
                    <div id="imgprev" style="position:absolute; display:block; box-shadow:2px 5px 10px #333; width:70%; height:0px; background:#999; left:15%; bottom:15px; "></div>
<img class='mqimg' src='spppimages/1.jpg' height='100px' />
<img class='mqimg' src='spppimages/2.jpg' height='100px' />
<img class='mqimg' src='spppimages/3.jpg' height='100px' />
<img class='mqimg' src='spppimages/4.jpg' height='100px' />
<img class='mqimg' src='spppimages/5.jpg' height='100px' />

try this:

download firefox, add the plugin "firebug" and "firepath"; after install them go to your webpage, start firebug and find the xpath of the element, it unique in the page so you can't make any mistake.

See picture:

browser.find_element_by_xpath('just copy and paste the Xpath').click()

I solved a situation where I needed a template for the element that would handle alternatively a regular URL or a javascript call, where the js function needs a reference to the calling element. In javascript, "this" works as a self reference only in the context of a form element, e.g., a button. I didn't want a button, just the apperance of a regular link.

Examples:

<a onclick="http://blahblah" href="http://blahblah" target="_blank">A regular link</a>
<a onclick="javascript:myFunc($(this));return false" href="javascript:myFunc($(this));"  target="_blank">javascript with self reference</a>

The href and onClick attributes have the same values, exept I append "return false" on onClick when it's a javascript call. Having "return false" in the called function did not work.

Now that the Web Audio API is here and gaining browser support, that could be a more robust option.

Zounds is a primitive wrapper around that API for playing simple one-shot sounds with a minimum of boilerplate at the point of use.

document.getElementById("myform").submit();

This won't work as your form tag doesn't have an id.

Change it like this and it should work:

<form name="myform" id="myform" action="action.php">

Another simple solution for this case using jQuery. Keep in mind it's not a good practice to use inline javascript.

JsFiddle

I've added IDs to html on the total price and on the buttons. Here is the jQuery.

$('#two').click(function(){
    $('#count').val('2');
    $('#total').text('Product price: $1000');
});

$('#four').click(function(){
    $('#count').val('4');
    $('#total').text('Product price: $2000');
});

Try this:

CSS

.style1{
    background-color:red;
    color:white;
    font-size:44px;
}

HTML

<div id="foo">hello world!</div>
<img src="zoom.png" onclick="myFunction()" />

Javascript

function myFunction()
{
    document.getElementById('foo').setAttribute("class", "style1");
}

If you do not use the sender argument, why not refactor the button handler implementation to separate function, and call it from wherever you want (from the button handler and from the other place).

Anyway, it is a better and cleaner design - a code that needs to be called on button handler AND from some other places deserves to be refactored to own function. Plus it will help you separate UI handling from application logic code. You will also have a nice name to the function, not just onDateSelectedButtonClick().

<input type="button" onclick="functionA();functionB();" />

function functionA()
{

}

function functionB()
{

}

You've got a few changes (this assumes you indeed still want to change the image with an ID of IMG, if not use Shadow Wizard's solution).

Remove a.src and replace with a:

<script type="text/javascript">
function changeImage(a) {
    document.getElementById("img").src=a;
}
</script>

Change your onclick attributes to include a string of the new image source instead of a literal:

onclick='changeImage( "1772031_29_b.jpg" );'

onclick="doSomething();doSomethingElse();"

But really, you're better off not using onclick at all and attaching the event handler to the DOM node through your Javascript code. This is known as unobtrusive javascript.

html:

<form method="post" name="form1" id="form1">    
    <input id="submit" name="submit" type="submit" value="Submit" onclick="eatFood();" />
</form>

Javascript: to submit the form using javascript

function eatFood() {
document.getElementById('form1').submit();
}

to show onclick message

function eatFood() {
alert('Form has been submitted');
}

<div id="about">About Snakelane</div>

   </label>



$scope.onLocationSelectionClicked = function($event) {
      if($scope.limitSelectionCountTo &&         $scope.selectedAuctions.locations.length == $scope.limitSelectionCountTo) {
         $event.currentTarget.checked=false;
      }
   };

I'm a little late to this party too, but I think I have something useful to add :o).

I created a UIButton subclass whose purpose is to be able to choose where the button's image is layout, either vertically or horizontally.

It means that you can make this kind of buttons :

Here the details about how to create these buttons with my class :

func makeButton (imageVerticalAlignment:LayoutableButton.VerticalAlignment, imageHorizontalAlignment:LayoutableButton.HorizontalAlignment, title:String) -> LayoutableButton {
    let button = LayoutableButton ()

    button.imageVerticalAlignment = imageVerticalAlignment
    button.imageHorizontalAlignment = imageHorizontalAlignment

    button.setTitle(title, for: .normal)

    // add image, border, ...

    return button
}

let button1 = makeButton(imageVerticalAlignment: .center, imageHorizontalAlignment: .left, title: "button1")
let button2 = makeButton(imageVerticalAlignment: .center, imageHorizontalAlignment: .right, title: "button2")
let button3 = makeButton(imageVerticalAlignment: .top, imageHorizontalAlignment: .center, title: "button3")
let button4 = makeButton(imageVerticalAlignment: .bottom, imageHorizontalAlignment: .center, title: "button4")
let button5 = makeButton(imageVerticalAlignment: .bottom, imageHorizontalAlignment: .center, title: "button5")
button5.contentEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)

To do that, I added 2 attributes : imageVerticalAlignment and imageHorizontalAlignment. Off course, If your button only have an image or a title ... don't use this class at all !

I also added an attribute named imageToTitleSpacing which allow you to adjust space between title and image.

This class try his best to be compatible if you want to use imageEdgeInsets, titleEdgeInsets and contentEdgeInsets directly or in combinaison with the new layout attributes.

As @ravron explains us, I try my best to make the button content edge correct (as you can see with the red borders).

You can also use it in Interface Builder :

1. Create a UIButton
2. Change the button class
3. Adjust Layoutable Attributes using "center", "top", "bottom", "left" or "right"

Here the code (gist) :

@IBDesignable

They should have the same time, the update is supposed to be atomic, meaning that whatever how long it takes to perform, the action is supposed to occurs as if all was done at the same time.

If you're experiencing a different behaviour, it's time to change for another DBMS.

Also see Yes, even you can use CPAN. It shows how you can use CPAN without having root or sudo access.

Why bother saving the field as readable? Just us AS

SELECT theTimeStamp, FROM_UNIXTIME(theTimeStamp) AS readableDate
               FROM theTable
               WHERE theTable.theField = theValue;

EDIT: Sorry, we store everything in milliseconds not seconds. Fixed it.

Just a note - if you're using ZSH and see the error

zsh: no matches found: HEAD^

You need to escape the ^

git reset --soft HEAD\^

2015 update, new MutationObserver is supported by modern browsers:

Chrome 18+, Firefox 14+, IE 11+, Safari 6+

If you need to support older ones, you may try to fall back to other approaches like the ones mentioned in this 5 (!) year old answer below. There be dragons. Enjoy :)

Someone else is changing the document? Because if you have full control over the changes you just need to create your own domChanged API - with a function or custom event - and trigger/call it everywhere you modify things.

The DOM Level-2 has Mutation event types, but older version of IE don't support it. Note that the mutation events are deprecated in the DOM3 Events spec and have a performance penalty.

You can try to emulate mutation event with onpropertychange in IE (and fall back to the brute-force approach if non of them is available).

For a full domChange an interval could be an over-kill. Imagine that you need to store the current state of the whole document, and examine every element's every property to be the same.

Maybe if you're only interested in the elements and their order (as you mentioned in your question), a getElementsByTagName("*") can work. This will fire automatically if you add an element, remove an element, replace elements or change the structure of the document.

I wrote a proof of concept:

(function (window) {
    var last = +new Date();
    var delay = 100; // default delay

    // Manage event queue
    var stack = [];

    function callback() {
        var now = +new Date();
        if (now - last > delay) {
            for (var i = 0; i < stack.length; i++) {
                stack[i]();
            }
            last = now;
        }
    }

    // Public interface
    var onDomChange = function (fn, newdelay) {
        if (newdelay) delay = newdelay;
        stack.push(fn);
    };

    // Naive approach for compatibility
    function naive() {

        var last = document.getElementsByTagName('*');
        var lastlen = last.length;
        var timer = setTimeout(function check() {

            // get current state of the document
            var current = document.getElementsByTagName('*');
            var len = current.length;

            // if the length is different
            // it's fairly obvious
            if (len != lastlen) {
                // just make sure the loop finishes early
                last = [];
            }

            // go check every element in order
            for (var i = 0; i < len; i++) {
                if (current[i] !== last[i]) {
                    callback();
                    last = current;
                    lastlen = len;
                    break;
                }
            }

            // over, and over, and over again
            setTimeout(check, delay);

        }, delay);
    }

    //
    //  Check for mutation events support
    //

    var support = {};

    var el = document.documentElement;
    var remain = 3;

    // callback for the tests
    function decide() {
        if (support.DOMNodeInserted) {
            window.addEventListener("DOMContentLoaded", function () {
                if (support.DOMSubtreeModified) { // for FF 3+, Chrome
                    el.addEventListener('DOMSubtreeModified', callback, false);
                } else { // for FF 2, Safari, Opera 9.6+
                    el.addEventListener('DOMNodeInserted', callback, false);
                    el.addEventListener('DOMNodeRemoved', callback, false);
                }
            }, false);
        } else if (document.onpropertychange) { // for IE 5.5+
            document.onpropertychange = callback;
        } else { // fallback
            naive();
        }
    }

    // checks a particular event
    function test(event) {
        el.addEventListener(event, function fn() {
            support[event] = true;
            el.removeEventListener(event, fn, false);
            if (--remain === 0) decide();
        }, false);
    }

    // attach test events
    if (window.addEventListener) {
        test('DOMSubtreeModified');
        test('DOMNodeInserted');
        test('DOMNodeRemoved');
    } else {
        decide();
    }

    // do the dummy test
    var dummy = document.createElement("div");
    el.appendChild(dummy);
    el.removeChild(dummy);

    // expose
    window.onDomChange = onDomChange;
})(window);

Usage:

onDomChange(function(){ 
    alert("The Times They Are a-Changin'");
});

This works on IE 5.5+, FF 2+, Chrome, Safari 3+ and Opera 9.6+

ls | grep "^abc"  

will give you all files beginning (which is what the OP specifically required) with the substringabc.
It operates only on the current directory whereas find operates recursively into sub folders.

To use find for only files starting with your string try

find . -name 'abc'*

class Program
{
    static void Main(string[] args)
    {

        int transactionDate = 20201010;
        int? transactionTime = 210000;

        var agreementDate = DateTime.Today;
        var previousDate = agreementDate.AddDays(-1);

        var agreementHour = 22;
        var agreementMinute = 0;
        var agreementSecond = 0;

        var startDate = new DateTime(previousDate.Year, previousDate.Month, previousDate.Day, agreementHour, agreementMinute, agreementSecond);
        var endDate = new DateTime(agreementDate.Year, agreementDate.Month, agreementDate.Day, agreementHour, agreementMinute, agreementSecond);

        DateTime selectedDate = Convert.ToDateTime(transactionDate.ToString().Substring(6, 2) + "/" + transactionDate.ToString().Substring(4, 2) + "/" + transactionDate.ToString().Substring(0, 4) + " " + string.Format("{0:00:00:00}", transactionTime));

        Console.WriteLine("Selected Date : " + selectedDate.ToString());
        Console.WriteLine("Start Date : " + startDate.ToString());
        Console.WriteLine("End Date : " + endDate.ToString());

        if (selectedDate > startDate && selectedDate <= endDate)
            Console.WriteLine("Between two dates..");
        else if (selectedDate <= startDate)
            Console.WriteLine("Less than or equal to the start date!");
        else if (selectedDate > endDate)
            Console.WriteLine("Greater than end date!");
        else
            Console.WriteLine("Out of date ranges!");
    }
}

Seems to work fine.

If you have an empty BEGIN ... END block you might see

Msg 102, Level 15, State 1, Line 10 Incorrect syntax near 'END'.

You may want to consider using Java EE, which includes the javax.servlet.* packages. If you require a specific version of the servlet api, for instance to target a specific web application server, you will probably want the Java EE version which matches, see this version table.

You have to import the font in your stylesheet like this:

@font-face{
    font-family: "Thonburi-Bold";
    src: url('Thonburi-Bold.ttf'),
    url('Thonburi-Bold.eot'); /* IE */
}

You can use Theme.applyStyle to modify your theme at runtime by applying another style to it.

Let's say you have these style definitions:

<style name="DefaultTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/md_lime_500</item>
    <item name="colorPrimaryDark">@color/md_lime_700</item>
    <item name="colorAccent">@color/md_amber_A400</item>
</style>

<style name="OverlayPrimaryColorRed">
    <item name="colorPrimary">@color/md_red_500</item>
    <item name="colorPrimaryDark">@color/md_red_700</item>
</style>

<style name="OverlayPrimaryColorGreen">
    <item name="colorPrimary">@color/md_green_500</item>
    <item name="colorPrimaryDark">@color/md_green_700</item>
</style>

<style name="OverlayPrimaryColorBlue">
    <item name="colorPrimary">@color/md_blue_500</item>
    <item name="colorPrimaryDark">@color/md_blue_700</item>
</style>

Now you can patch your theme at runtime like so:

getTheme().applyStyle(R.style.OverlayPrimaryColorGreen, true);

The method applyStylehas to be called before the layout gets inflated! So unless you load the view manually you should apply styles to the theme before calling setContentView in your activity.

Of course this cannot be used to specify an arbitrary color, i.e. one out of 16 million (256³) colors. But if you write a small program that generates the style definitions and the Java code for you then something like one out of 512 (8³) should be possible.

What makes this interesting is that you can use different style overlays for different aspects of your theme. Just add a few overlay definitions for colorAccent for example. Now you can combine different values for primary color and accent color almost arbitrarily.

You should make sure that your overlay theme definitions don't accidentally inherit a bunch of style definitions from a parent style definition. For example a style called AppTheme.OverlayRed implicitly inherits all styles defined in AppTheme and all these definitions will also be applied when you patch the master theme. So either avoid dots in the overlay theme names or use something like Overlay.Red and define Overlay as an empty style.

The CBO builds a decision tree, estimating the costs of each possible execution path available per query. The costs are set by the CPU_cost or I/O_cost parameter set on the instance. And the CBO estimates the costs, as best it can with the existing statistics of the tables and indexes that the query will use. You should not tune your query based on cost alone. Cost allows you to understand WHY the optimizer is doing what it does. Without cost you could figure out why the optimizer chose the plan it did. Lower cost does not mean a faster query. There are cases where this is true and there will be cases where this is wrong. Cost is based on your table stats and if they are wrong the cost is going to be wrong.

When tuning your query, you should take a look at the cardinality and the number of rows of each step. Do they make sense? Is the cardinality the optimizer is assuming correct? Is the rows being return reasonable. If the information present is wrong then its very likely the optimizer doesn't have the proper information it needs to make the right decision. This could be due to stale or missing statistics on the table and index as well as cpu-stats. Its best to have stats updated when tuning a query to get the most out of the optimizer. Knowing your schema is also of great help when tuning. Knowing when the optimizer chose a really bad decision and pointing it in the correct path with a small hint can save a load of time.

AndroidX - Android Extension Library

From AndroidX documentation

We are rolling out a new package structure to make it clearer which packages are bundled with the Android operating system, and which are packaged with your app's APK. Going forward, the android.* package hierarchy will be reserved for Android packages that ship with the operating system. Other packages will be issued in the new androidx.* package hierarchy as part of the AndroidX library.

Need of AndroidX

AndroidX is a redesigned library to make package names more clear. So from now on android hierarchy will be for only android default classes, which comes with android operating system and other library/dependencies will be part of androidx (makes more sense). So from now on all the new development will be updated in androidx.

com.android.support.** : androidx.
com.android.support:appcompat-v7 : androidx.appcompat:appcompat com.android.support:recyclerview-v7 : androidx.recyclerview:recyclerview com.android.support:design : com.google.android.material:material

Complete Artifact mappings for AndroidX packages

AndroidX uses Semantic-version

Previously, support library used the SDK version but AndroidX uses the Semantic-version. It’s going to re-version from 28.0.0 ? 1.0.0.

How to migrate current project

In Android Studio 3.2 (September 2018), there is a direct option to migrate existing project to AndroidX. This refactor all packages automatically.

Before you migrate, it is strongly recommended to backup your project.

Existing project

• Android Studio > Refactor Menu > Migrate to AndroidX...
• It will analyze and will open Refractor window in bottom. Accept changes to be done.

New project

Put these flags in your gradle.properties

android.enableJetifier=true
android.useAndroidX=true

Check @Library mappings for equal AndroidX package.

Check @Official page of Migrate to AndroidX

What is Jetifier?

Bugs of migrating

• If you build app, and find some errors after migrating, then you need to fix those minor errors. You will not get stuck there, because that can be easily fixed.
• 3rd party libraries are not converted to AndroidX in directory, but they get converted at run time by Jetifier, so don't worry about compile time errors, your app will run perfectly.

Support 28.0.0 is last release?

From Android Support Revision 28.0.0

This will be the last feature release under the android.support packaging, and developers are encouraged to migrate to AndroidX 1.0.0

So go with AndroidX, because Android will update only androidx package from now.

insert is better from the point of exception safety.

The expression map[key] = value is actually two operations:

1. map[key] - creating a map element with default value.
2. = value - copying the value into that element.

An exception may happen at the second step. As result the operation will be only partially done (a new element was added into map, but that element was not initialized with value). The situation when an operation is not complete, but the system state is modified, is called the operation with "side effect".

insert operation gives a strong guarantee, means it doesn't have side effects (https://en.wikipedia.org/wiki/Exception_safety). insert is either completely done or it leaves the map in unmodified state.

http://www.cplusplus.com/reference/map/map/insert/:

If a single element is to be inserted, there are no changes in the container in case of exception (strong guarantee).

In addition to the answers already given it will be quicker if you use OrElse instead of Or because the second test is short circuited. This is especially true if you know that one string is more likely than the other in which case place this first:

If strMyString.Contains("Most Likely To Find") OrElse strMyString.Contains("Less Likely to Find") Then
    'Code
End if

The basic setup of decorators is like this:

InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);

The key issue in this snippet is the value of encoding. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.

For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.

Most network protocols use a header or other metadata to explicitly note the character encoding.

In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.

Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!

Select Operation : This operation is used to select rows from a table (relation) that specifies a given logic, which is called as a predicate. The predicate is a user defined condition to select rows of user's choice.

Project Operation : If the user is interested in selecting the values of a few attributes, rather than selection all attributes of the Table (Relation), then one should go for PROJECT Operation.

This page lists some simple hash functions that tend to decently in general, but any simple hash has pathological cases where it doesn't work well.

getResource by example:

package szb.testGetResource;
public class TestGetResource {
    private void testIt() {
        System.out.println("test1: "+TestGetResource.class.getResource("test.css"));
        System.out.println("test2: "+getClass().getResource("test.css"));
    }
    public static void main(String[] args) {
        new TestGetResource().testIt();
    }
}

output:

test1: file:/home/szb/projects/test/bin/szb/testGetResource/test.css
test2: file:/home/szb/projects/test/bin/szb/testGetResource/test.css

Reviving an old question because it seems to appear at the top of search results.

I wanted to retain transition effects while still being able to style the actionlink so I came up with this solution.

1. I wrapped the action link with a div that would contain the parent style:

<div class="parent-style-one">
      @Html.ActionLink("Homepage", "Home", "Home")
</div>

2. Next I create the CSS for the div, this will be the parent css and will be inherited by the child elements such as the action link.

  .parent-style-one {
     /* your styles here */
  }

3. Because all an action link is, is an element when broken down as html so you just need to target that element in your css selection:

  .parent-style-one a {
     text-decoration: none;
  }

4. For transition effects I did this:

  .parent-style-one a:hover {
        text-decoration: underline;
        -webkit-transition-duration: 1.1s; /* Safari */
        transition-duration: 1.1s;         
  }

This way I only target the child elements of the div in this case the action link and still be able to apply transition effects.

I fix it just changing the name to lowercase and now Eclipse recognizes the package.

XCode 11.3 and prior:

Debug -> Location -> Custom Location

XCode 11.4+:

Features -> Location -> Custom Location

To find out which XCode version you have

$ /usr/bin/xcodebuild -version

If you want to get a list of files that are only in one directory and not their sub directories and only their file names:

diff -q /dir1 /dir2 | grep /dir1 | grep -E "^Only in*" | sed -n 's/[^:]*: //p'

If you want to recursively list all the files and directories that are different with their full paths:

diff -rq /dir1 /dir2 | grep -E "^Only in /dir1*" | sed -n 's/://p' | awk '{print $3"/"$4}'

This way you can apply different commands to all the files.

For example I could remove all the files and directories that are in dir1 but not dir2:

diff -rq /dir1 /dir2 | grep -E "^Only in /dir1*" | sed -n 's/://p' | awk '{print $3"/"$4}' xargs -I {} rm -r {}

I use a customized version of DX Auth. I found it simple to use, extremely easy to modify and it has a user guide (with great examples) that is very similar to Code Igniter's.

If you have the SQL Server 2008 Installation media, you can install just the Client/Workstation Components. You don't have to install the database engine to install the workstation tools, but if you plan to do Integration Services development, you do need to install the Integration Services Engine on the workstation for BIDS to be able to be used for development. Keep in mind that Visual Studio 2010 does not have BI development support currently, so you have to install BIDS from the SQL Installation media and use the Visual Studio 2008 BI Development Studio that installs under the SQL Server 2008 folder in Program Files if you need to do any SSIS, SSRS, or SSAS development from the workstation.

As mentioned in the comments you can download Management Studio Express free from Microsoft, but if you already have the installation media for SQL Server Standard/Enterprise/Developer edition, you'd be better off using what you have.

Download SSMS 2008 Express

You can also use the same syntax for an array. For example, searching within a Pandas series:

ser = pd.Series(['some', 'strings', 'to', 'query'])

if item in ser.values:
    # do stuff

It may has not helped OP, but it solved my problem. This answer is to help others who have not tried the command mentioned in OP's question.

Just use npm install -g @angular/cli@latest. It did the trick for me.

$string="1,2,3,4,5";
$array=array_map('intval', explode(',', $string));
$array = implode("','",$array);
$query=mysqli_query($conn, "SELECT name FROM users WHERE id IN ('".$array."')");

NB: the syntax is:

SELECT * FROM table WHERE column IN('value1','value2','value3')

Oddly, the only decent JSON processor mentioned so far has been GSON.

Here are more good choices:

• Jackson (Github) -- powerful data binding (JSON to/from POJOs), streaming (ultra fast), tree model (convenient for untyped access)
• Flex-JSON -- highly configurable serialization

EDIT (Aug/2013):

One more to consider:

• Genson -- functionality similar to Jackson, aimed to be easier to configure by developer

Instead of doing all these greps and stuff, I'd advise you to use ps capabilities of changing output format.

ps -o cmd= -p 12345

You get the cmmand line of a process with the pid specified and nothing else.

This is POSIX-conformant and may be thus considered portable.

The answer using jQuery that everyone seems to like has a major flaw, which is it is not scalable (at least as it is written). I think Martin Hansen has the right idea, which is to use HTML5 data-* attributes. And you can even use the apostrophe correctly:

html:

<div class="task" data-task-owner="Joe">mop kitchen</div>
<div class="task" data-task-owner="Charles" data-apos="1">vacuum hallway</div>

css:

div.task:before { content: attr(data-task-owner)"'s task - " ; }
div.task[data-apos]:before { content: attr(data-task-owner)"' task - " ; }

output:

Joe's task - mop kitchen
Charles' task - vacuum hallway

I know this is old, but for local dev, this is what got things back to a production .env file:

rm bootstrap/cache/config.php

then

php artisan config:cache
php artisan config:clear
php artisan cache:clear

While they are both rooted in C, they are two completely different languages.

A major difference is that Objective-C is focused on runtime-decisions for dispatching and heavily depends on its runtime library to handle inheritance and polymorphism, while in C++ the focus usually lies on static, compile time, decisions.

Regarding libraries, you can use plain C libraries in both languages - but their native libraries are completely different.

Of interest though is that you can mix both languages (with some limitations). The result is called Objective-C++.

Apple states in the latest version of Building Cocoa Apps,

The Swift compiler does not include a preprocessor. Instead, it takes advantage of compile-time attributes, build configurations, and language features to accomplish the same functionality. For this reason, preprocessor directives are not imported in Swift.

The # character appears to still be how you work with various build configurations and things like that, but it looks like they're trying to cut back on your need for most preprocessing in the vein of pragma and forward you to other language features altogether. Perhaps this is to aid in the operation of the Playgrounds and the REPL behaving as close as possible to the fully compiled code.

Something to try --- tell python to not use https with the index directive and a http:// address (not https://)

You may be behind a corporate firewall and Ive have experiences where even the above failed, though Im not going to pretend like I know enough about firewalls or SSL to understand why. In that case the only way I was able to get around that was to get a certificate file and pass it to python. See kenorb’s answer here for details.

For anybody reading this in 2019, after React 16.8 was released, take a look at the React Hooks. It really simplifies handling states in components. The docs are very well written with an example of exactly what you need.

The quick answer I suggest is:

response.Result.Content.ReadAsStringAsync().Result

INSERT INTO Test([col1],[col2]) (
    SELECT 
        a.Name AS [col1],
        b.sub AS [col2] 
    FROM IdTable b 
    INNER JOIN Nametable a ON b.no = a.no
)

count_letters=""

number=count_letters.count("")

print number

The answer is .IsPostBack as suggested by @Kundan Singh Chouhan. Just to add to it, move your code into a separate method from Page_Load

private void PopulateFields()
{
  using(SqlConnection con1 = new SqlConnection("Data Source=USER-PC;Initial Catalog=webservice_database;Integrated Security=True"))
  {
    DataTable dt = new DataTable();
    con1.Open();
    SqlDataReader myReader = null;  
    SqlCommand myCommand = new SqlCommand("select * from customer_registration where username='" + Session["username"] + "'", con1);

    myReader = myCommand.ExecuteReader();

    while (myReader.Read())
    {
        TextBoxPassword.Text = (myReader["password"].ToString());
        TextBoxRPassword.Text = (myReader["retypepassword"].ToString());
        DropDownListGender.SelectedItem.Text = (myReader["gender"].ToString());
        DropDownListMonth.Text = (myReader["birth"].ToString());
        DropDownListYear.Text = (myReader["birth"].ToString());
        TextBoxAddress.Text = (myReader["address"].ToString());
        TextBoxCity.Text = (myReader["city"].ToString());
        DropDownListCountry.SelectedItem.Text = (myReader["country"].ToString());
        TextBoxPostcode.Text = (myReader["postcode"].ToString());
        TextBoxEmail.Text = (myReader["email"].ToString());
        TextBoxCarno.Text = (myReader["carno"].ToString());
    }
    con1.Close();
  }//end using
}

Then call it in your Page_Load

protected void Page_Load(object sender, EventArgs e)
{

    if(!Page.IsPostBack)
    {
       PopulateFields();
    }
}

I had an issue with this because I had accidentally installed XAMPP to c:\windows\program files (x86) which caused a Windows permissions issue.

The installation says not to install it there, but I thought it had said to install it there.

I uninstalled and reinstalled to c:\xampp and it worked.

I'd suggest that the -i means it does match "ABC", but the difference is in the output. -i doesn't manipulate the input, so it won't change "ABC" to "abc" because you specified "abc" as the pattern. -o says it only shows the part of the output that matches the pattern specified, it doesn't say about matching input.

The output of echo "ABC" | grep -i abc is ABC, the -o shows output matching "abc" so nothing shows:

Naos:~ mattlacey$ echo "ABC" | grep -i abc | grep -o abc
Naos:~ mattlacey$ echo "ABC" | grep -i abc | grep -o ABC
ABC

If you know on what port it would be running(by default it would be 6379), you can use below command to get the pid of the process using that port and then can execute kill command for the same pid.

sudo lsof -i : <port> | awk '{print $2}'

the above command will give you pid.

kill <pid>;

This would shutdown your server.

Quite strange that manually casting a list is still not provided by some tool box implementing something like:

@SuppressWarnings({ "unchecked", "rawtypes" })
public static <T extends E, E> List<T> cast(List<E> list) {
    return (List) list;
}

Of course, this won't check items one by one, but that is precisely what we want to avoid here, if we well know that our implementation only provides the sub-type.

I realise that's not the case here but it might help someone.

Double-check you didn't create the conf file in /etc/apache2/sites-enabled by mistake. You get the same error.

To expound on cletus' answer, at runtime all record of the generic types is removed. Generics are processed only in the compiler and are used to provide additional type safety. They are really just shorthand that allows the compiler to insert typecasts at the appropriate places. For example, previously you'd have to do the following:

List x = new ArrayList();
x.add(new SomeClass());
Iterator i = x.iterator();
SomeClass z = (SomeClass) i.next();

becomes

List<SomeClass> x = new ArrayList<SomeClass>();
x.add(new SomeClass());
Iterator<SomeClass> i = x.iterator();
SomeClass z = i.next();

This allows the compiler to check your code at compile-time, but at runtime it still looks like the first example.

ConfigurationSettings.AppSettings is obsolete, you should use ConfigurationManager.AppSettings instead (you will need to add a reference to System.Configuration)

int value = Int32.Parse(ConfigurationManager.AppSettings["StartingMonthColumn"]);

If you still have problems reading in your app settings then check that your app.config file is named correctly. Specifically, it should be named according to the executing assembly i.e. MyApp.exe.config, and should reside in the same directory as MyApp.exe.

Haven't tried it yet, but Configgy looks promising for both configuration and logging:

http://github.com/robey/configgy/tree/master

2**2 = 2 power-of 2

2*2 = 2 times 2

You can use the -B and -A to print lines before and after the match.

grep -i -B 10 'error' data

Will print the 10 lines before the match, including the matching line itself.

You may have issues with column width, but you can set those explicitly.

<table>
  <tr>
    <td>
       <form>
         <table>
           <tr>
             <td></td> 
             <td></td> 
             <td></td> 
             <td></td> 
             <td></td> 
             <td></td> 
           </tr>
         </table>
       </form>
     </td>
    </tr>
  <tr>
    <td>
       <form>
         <table>
           <tr>
             <td></td> 
             <td></td> 
             <td></td> 
             <td></td> 
             <td></td> 
             <td></td> 
           </tr>
         </table>
       </form>
     </td>
    </tr>
  </table>

You may want to also consider making it a single form, and then using jQuery to select the form elements from the row you want, serialize them, and submit them as the form.

See: http://api.jquery.com/serialize/

Also, there are a number of very nice grid plugins: http://www.google.com/search?q=jquery+grid&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a

With a simple generic function you can make this very easy. Just do this:

return ConvertFromDBVal<string>(accountNumber);

using the function:

public static T ConvertFromDBVal<T>(object obj)
{
    if (obj == null || obj == DBNull.Value)
    {
        return default(T); // returns the default value for the type
    }
    else
    {
        return (T)obj;
    }
}

Edit your Apache configuration file on the "mirror" server (the server with the problem), and comment-out the following line:

AddDefaultCharset UTF-8

Then restart Apache:

service httpd restart

The problem is that the "AddDefaultCharset UTF-8" line overrides the Content-Type specified in the .html files; e.g.:

<meta http-equiv=Content-Type content="text/html; charset=windows-1252">

The most common symptom is that character codes above 127 display as black diamonds with question marks on them (in Chrome, Safari or Firefox), or as little boxes (in IE and Opera). HTML files generated by Microsoft Word usually have many such characters, the most common one being character code 160 = 0xA0, which is equivalent to " " in the Windows-1252 encoding, and is often found between span tags, like this:

<span style="mso-spacerun: yes">ááá </span>

I was encountering the same issue. In my App build.gradle I had

apply plugin: 'com.android.application'
apply plugin: 'dexguard'
apply plugin: 'io.fabric'

I just switched Dexguard and Fabric, then it worked!

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'dexguard'

Personally I find

if (id in tutorTimes === false) { ... }

easier to read than

if (!(id in tutorTimes)) { ... }

but both will work.

In java there is a length field that you can use on any array to find out it's size:

    String[] s = new String[10];
    System.out.println(s.length);

The difference is in the scope of the variable. The @version is available to all methods of the class instance.

The short answer, if you're in the controller and you need to make the variable available to the view then use @variable.

For a much longer answer try this: http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_classes.html

std::string bin(uint_fast8_t i){return !i?"0":i==1?"1":bin(i/2)+(i%2?'1':'0');}

1. Open the xampp/php/php.ini file in any editor
2. Search ";extension=php_intl.dll"

3. Remove the starting semicolon ( ; )

   Like: ;extension=php_intl.dll to extension=php_intl.dll

This helped me.

Try below:

   <Spinner
    android:id="@+id/YourSpinnerId"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:prompt="Gender" />

Use

document.getElementById('<%= txt_model_code.ClientID %>')

instead of

document.getElementById('txt_model_code')`

Also you can use onClientClick instead of onClick.

One way is to use window.print() function. Which does not require any library

Pros

1.No external library require.

2.We can print only selected parts of body also.

3.No css conflicts and js issues.

4.Core html/js functionality

---Simply add below code

CSS to

@media print {
        body * {
            visibility: hidden; // part to hide at the time of print
            -webkit-print-color-adjust: exact !important; // not necessary use         
               if colors not visible
        }

        #printBtn {
            visibility: hidden !important; // To hide 
        }

        #page-wrapper * {
            visibility: visible; // Print only required part
            text-align: left;
            -webkit-print-color-adjust: exact !important;
        }
    }

JS code - Call bewlow function on btn click

$scope.printWindow = function () {
  window.print()
}

Note: Use !important in every css object

Example -

.legend  {
  background: #9DD2E2 !important;
}

Here a one-file solution (based on elegant answer by @Marcin:

#include <iostream>

#define ENUM_TXT \
X(Red) \
X(Green) \
X(Blue) \
X(Cyan) \
X(Yellow) \
X(Magenta) \

enum Colours {
#   define X(a) a,
ENUM_TXT
#   undef X
    ColoursCount
};

char const* const colours_str[] = {
#   define X(a) #a,
ENUM_TXT
#   undef X
    0
};

std::ostream& operator<<(std::ostream& os, enum Colours c)
{
    if (c >= ColoursCount || c < 0) return os << "???";
    return os << colours_str[c] << std::endl;
}

int main()
{
    std::cout << Red << Blue << Green << Cyan << Yellow << Magenta << std::endl;
}

You can change the passphrase for your private key by doing:

ssh-keygen -f ~/.ssh/id_rsa -p

Run php -f /common/configs/config_templates.inc.php to verify the validity of the PHP syntax in the file.

I would like to show another cross-browser way which can solve this question using CSS3 calc().

We can use the calc() function to control the margin-top property of the child div when it's positioned absolute relative to the parent div.

The main advantage using calc() is that the parent element height can be changed at anytime and the child div will always be aligned to the middle.

The margin-top calculation is made dynamically (by css and not by a script and it's a very big advantage).

something along the lines of this maybe (or as we used to say, this should work).

You don't really need the directive, can achieve it by using the ng-init and ng-checked. below demo link shows how to set the initial value for checkbox in angularjs.

demo link:

<form>
    <div>
      Released<input type="checkbox" ng-model="Released" ng-bind-html="ACR.Released" ng-true-value="true" ng-false-value="false" ng-init='Released=true' ng-checked='true' /> 
      Inactivated<input type="checkbox" ng-model="Inactivated" ng-bind-html="Inactivated" ng-true-value="true" ng-false-value="false" ng-init='Inactivated=false' ng-checked='false' /> 
      Title Changed<input type="checkbox" ng-model="Title" ng-bind-html="Title" ng-true-value="true" ng-false-value="false" ng-init='Title=false' ng-checked='false' />
    </div>
    <br/>
    <div>Released value is  <b>{{Released}}</b></div>
    <br/>
    <div>Inactivated  value is  <b>{{Inactivated}}</b></div>
    <br/>
    <div>Title  value is  <b>{{Title}}</b></div>
    <br/>
  </form>

// Code goes here

  var app = angular.module("myApp", []);
        app.controller("myCtrl", function ($scope) {

         });    

You can use

SELECT SYS_EXTRACT_UTC(TIMESTAMP '2000-03-28 11:30:00.00 -02:00') FROM DUAL;

You may also need to change your timezone

ALTER SESSION SET TIME_ZONE = 'Europe/Berlin';

Or read it

SELECT SESSIONTIMEZONE, CURRENT_TIMESTAMP FROM dual;

If you want the structure to have a certain size with GCC for example use __attribute__((packed)).

On Windows you can set the alignment to one byte when using the cl.exe compier with the /Zp option.

Usually it is easier for the CPU to access data that is a multiple of 4 (or 8), depending platform and also on the compiler.

So it is a matter of alignment basically.

You need to have good reasons to change it.

window.scrollTo(0,1);

this will help you but this javascript is may not work in all browsers

I have noticed that XMLSpy(at least 2011 version)needs a targetNameSpace defined if elementFormDefault="qualified" is used. Otherwise won't validate. And also won't generate xmls with namespace prefixes

SEARCH does not return 0 if there is no match, it returns #VALUE!. So you have to wrap calls to SEARCH with IFERROR.

For example...

=IF(IFERROR(SEARCH("cat", A1), 0), "cat", "none")

or

=IF(IFERROR(SEARCH("cat",A1),0),"cat",IF(IFERROR(SEARCH("22",A1),0),"22","none"))

Here, IFERROR returns the value from SEARCH when it works; the given value of 0 otherwise.

This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):

It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.

Here are the commands again for easier copy-pasting:

openssl rsa                                                -in $FF -out $TF
openssl rsa -aes256                                        -in $FF -out $TF
openssl pkcs8 -topk8 -nocrypt                              -in $FF -out $TF
openssl pkcs8 -topk8 -v2 aes-256-cbc -v2prf hmacWithSHA256 -in $FF -out $TF

and

openssl rsa -check -in $FF
openssl rsa -text  -in $FF

Potential answer for SQL Server

Interesting I just ran a test using LinqPad with SQL Server which should be just running Linq to SQL underneath and it generates the following SQL statement.

Records .Where(r => r.Name.Contains("lkjwer--_~[]"))

-- Region Parameters
DECLARE @p0 VarChar(1000) = '%lkjwer--~_~~~[]%'
-- EndRegion
SELECT [t0].[ID], [t0].[Name]
FROM [RECORDS] AS [t0]
WHERE [t0].[Name] LIKE @p0 ESCAPE '~'

So I haven't tested it yet but it looks like potentially the ESCAPE '~' keyword may allow for automatic escaping of a string for use within a like expression.

Since I wrote my prior answer, I have formulated a new definition of the declarative property which is quoted below. I have also defined imperative programming as the dual property.

This definition is superior to the one I provided in my prior answer, because it is succinct and it is more general. But it may be more difficult to grok, because the implication of the incompleteness theorems applicable to programming and life in general are difficult for humans to wrap their mind around.

The quoted explanation of the definition discusses the role pure functional programming plays in declarative programming.

All exotic types of programming fit into the following taxonomy of declarative versus imperative, since the following definition claims they are duals.

Declarative vs. Imperative

The declarative property is weird, obtuse, and difficult to capture in a technically precise definition that remains general and not ambiguous, because it is a naive notion that we can declare the meaning (a.k.a semantics) of the program without incurring unintended side effects. There is an inherent tension between expression of meaning and avoidance of unintended effects, and this tension actually derives from the incompleteness theorems of programming and our universe.

It is oversimplification, technically imprecise, and often ambiguous to define declarative as “what to do” and imperative as “how to do”. An ambiguous case is the “what” is the “how” in a program that outputs a program— a compiler.

Evidently the unbounded recursion that makes a language Turing complete, is also analogously in the semantics— not only in the syntactical structure of evaluation (a.k.a. operational semantics). This is logically an example analogous to Gödel's theorem— “any complete system of axioms is also inconsistent”. Ponder the contradictory weirdness of that quote! It is also an example that demonstrates how the expression of semantics does not have a provable bound, thus we can't prove2 that a program (and analogously its semantics) halt a.k.a. the Halting theorem.

The incompleteness theorems derive from the fundamental nature of our universe, which as stated in the Second Law of Thermodynamics is “the entropy (a.k.a. the # of independent possibilities) is trending to maximum forever”. The coding and design of a program is never finished— it's alive!— because it attempts to address a real world need, and the semantics of the real world are always changing and trending to more possibilities. Humans never stop discovering new things (including errors in programs ;-).

To precisely and technically capture this aforementioned desired notion within this weird universe that has no edge (ponder that! there is no “outside” of our universe), requires a terse but deceptively-not-simple definition which will sound incorrect until it is explained deeply.

Definition:

---

The declarative property is where there can exist only one possible set of statements that can express each specific modular semantic.

The imperative property3 is the dual, where semantics are inconsistent under composition and/or can be expressed with variations of sets of statements.

---

This definition of declarative is distinctively local in semantic scope, meaning that it requires that a modular semantic maintain its consistent meaning regardless where and how it's instantiated and employed in global scope. Thus each declarative modular semantic should be intrinsically orthogonal to all possible others— and not an impossible (due to incompleteness theorems) global algorithm or model for witnessing consistency, which is also the point of “More Is Not Always Better” by Robert Harper, Professor of Computer Science at Carnegie Mellon University, one of the designers of Standard ML.

Examples of these modular declarative semantics include category theory functors e.g. the Applicative, nominal typing, namespaces, named fields, and w.r.t. to operational level of semantics then pure functional programming.

Thus well designed declarative languages can more clearly express meaning, albeit with some loss of generality in what can be expressed, yet a gain in what can be expressed with intrinsic consistency.

An example of the aforementioned definition is the set of formulas in the cells of a spreadsheet program— which are not expected to give the same meaning when moved to different column and row cells, i.e. cell identifiers changed. The cell identifiers are part of and not superfluous to the intended meaning. So each spreadsheet result is unique w.r.t. to the cell identifiers in a set of formulas. The consistent modular semantic in this case is use of cell identifiers as the input and output of pure functions for cells formulas (see below).

Hyper Text Markup Language a.k.a. HTML— the language for static web pages— is an example of a highly (but not perfectly3) declarative language that (at least before HTML 5) had no capability to express dynamic behavior. HTML is perhaps the easiest language to learn. For dynamic behavior, an imperative scripting language such as JavaScript was usually combined with HTML. HTML without JavaScript fits the declarative definition because each nominal type (i.e. the tags) maintains its consistent meaning under composition within the rules of the syntax.

A competing definition for declarative is the commutative and idempotent properties of the semantic statements, i.e. that statements can be reordered and duplicated without changing the meaning. For example, statements assigning values to named fields can be reordered and duplicated without changed the meaning of the program, if those names are modular w.r.t. to any implied order. Names sometimes imply an order, e.g. cell identifiers include their column and row position— moving a total on spreadsheet changes its meaning. Otherwise, these properties implicitly require global consistency of semantics. It is generally impossible to design the semantics of statements so they remain consistent if randomly ordered or duplicated, because order and duplication are intrinsic to semantics. For example, the statements “Foo exists” (or construction) and “Foo does not exist” (and destruction). If one considers random inconsistency endemical of the intended semantics, then one accepts this definition as general enough for the declarative property. In essence this definition is vacuous as a generalized definition because it attempts to make consistency orthogonal to semantics, i.e. to defy the fact that the universe of semantics is dynamically unbounded and can't be captured in a global coherence paradigm.

Requiring the commutative and idempotent properties for the (structural evaluation order of the) lower-level operational semantics converts operational semantics to a declarative localized modular semantic, e.g. pure functional programming (including recursion instead of imperative loops). Then the operational order of the implementation details do not impact (i.e. spread globally into) the consistency of the higher-level semantics. For example, the order of evaluation of (and theoretically also the duplication of) the spreadsheet formulas doesn't matter because the outputs are not copied to the inputs until after all outputs have been computed, i.e. analogous to pure functions.

C, Java, C++, C#, PHP, and JavaScript aren't particularly declarative. Copute's syntax and Python's syntax are more declaratively coupled to intended results, i.e. consistent syntactical semantics that eliminate the extraneous so one can readily comprehend code after they've forgotten it. Copute and Haskell enforce determinism of the operational semantics and encourage “don't repeat yourself” (DRY), because they only allow the pure functional paradigm.

---

2 Even where we can prove the semantics of a program, e.g. with the language Coq, this is limited to the semantics that are expressed in the typing, and typing can never capture all of the semantics of a program— not even for languages that are not Turing complete, e.g. with HTML+CSS it is possible to express inconsistent combinations which thus have undefined semantics.

3 Many explanations incorrectly claim that only imperative programming has syntactically ordered statements. I clarified this confusion between imperative and functional programming. For example, the order of HTML statements does not reduce the consistency of their meaning.

Edit: I posted the following comment to Robert Harper's blog:

in functional programming ... the range of variation of a variable is a type

Depending on how one distinguishes functional from imperative programming, your ‘assignable’ in an imperative program also may have a type placing a bound on its variability.

The only non-muddled definition I currently appreciate for functional programming is a) functions as first-class objects and types, b) preference for recursion over loops, and/or c) pure functions— i.e. those functions which do not impact the desired semantics of the program when memoized (_{^{thus perfectly pure functional programming doesn't exist in a general purpose denotational semantics due to impacts of operational semantics, e.g. memory allocation}}).

The idempotent property of a pure function means the function call on its variables can be substituted by its value, which is not generally the case for the arguments of an imperative procedure. Pure functions seem to be declarative w.r.t. to the uncomposed state transitions between the input and result types.

But the composition of pure functions does not maintain any such consistency, because it is possible to model a side-effect (global state) imperative process in a pure functional programming language, e.g. Haskell's IOMonad and moreover it is entirely impossible to prevent doing such in any Turing complete pure functional programming language.

As I wrote in 2012 which seems to the similar consensus of comments in your recent blog, that declarative programming is an attempt to capture the notion that the intended semantics are never opaque. Examples of opaque semantics are dependence on order, dependence on erasure of higher-level semantics at the operational semantics layer (e.g. casts are not conversions and reified generics limit higher-level semantics), and dependence on variable values which can not be checked (proved correct) by the programming language.

Thus I have concluded that only non-Turing complete languages can be declarative.

Thus one unambiguous and distinct attribute of a declarative language could be that its output can be proven to obey some enumerable set of generative rules. For example, for any specific HTML program (ignoring differences in the ways interpreters diverge) that is not scripted (i.e. is not Turing complete) then its output variability can be enumerable. Or more succinctly an HTML program is a pure function of its variability. Ditto a spreadsheet program is a pure function of its input variables.

So it seems to me that declarative languages are the antithesis of unbounded recursion, i.e. per Gödel's second incompleteness theorem self-referential theorems can't be proven.

Lesie Lamport wrote a fairytale about how Euclid might have worked around Gödel's incompleteness theorems applied to math proofs in the programming language context by to congruence between types and logic (Curry-Howard correspondence, etc).

Following a Google...

Taking the code from the website:

CREATE TABLE CRLF
    (
        col1 VARCHAR(1000)
    )

INSERT CRLF SELECT 'The quick brown@'
INSERT CRLF SELECT 'fox @jumped'
INSERT CRLF SELECT '@over the '
INSERT CRLF SELECT 'log@'

SELECT col1 FROM CRLF

Returns:

col1
-----------------
The quick brown@
fox @jumped
@over the
log@

(4 row(s) affected)


UPDATE CRLF
SET col1 = REPLACE(col1, '@', CHAR(13))

Looks like it can be done by replacing a placeholder with CHAR(13)

Good question, never done it myself :)

What are the steps for that? where is AppCompat located?

Download the support library here:

http://developer.android.com/tools/support-library/setup.html

If you are using Eclipse:

Go to the tabs at the top and select ( Windows -> Android SDK Manager ). Under the 'extras' section, check 'Android Support Library' and check it for installation.

After that, the AppCompat library can be found at:

android-sdk/extras/android/support/v7/appcompat

You need to reference this AppCompat library in your Android project.

Import the library into Eclipse.

1. Right click on your Android project.
2. Select properties.
3. Click 'add...' at the bottom to add a library.
4. Select the support library
5. Clean and rebuild your project.

Use MethodInvoker for updating label text in other thread.

private void AggiornaContatore()
{
    MethodInvoker inv = delegate 
    {
      this.lblCounter.Text = this.index.ToString(); 
    }

 this.Invoke(inv);
}

You are getting the error because your UI thread is holding the label, and since you are trying to update it through another thread you are getting cross thread exception.

if you have a subfolder, which was cloned from other git-Repository, first you have to remove the $.git$ file from the child-Repository: rm -rf .git after that you can change to parent folder and use git add -A.

java.util.Calendar.getInstance() represents the current time using the current locale and timezone.

You could also choose to import and use Joda-Time or one of the forks for Android.

The easiest way is to use to_datetime:

df['col'] = pd.to_datetime(df['col'])

It also offers a dayfirst argument for European times (but beware this isn't strict).

Here it is in action:

In [11]: pd.to_datetime(pd.Series(['05/23/2005']))
Out[11]:
0   2005-05-23 00:00:00
dtype: datetime64[ns]

You can pass a specific format:

In [12]: pd.to_datetime(pd.Series(['05/23/2005']), format="%m/%d/%Y")
Out[12]:
0   2005-05-23
dtype: datetime64[ns]

Here's a working example, which is a fork of this answer:

$(document).ready(function(){
    FB.login(function(response) {
        if (response.status == 'connected') {
            var user_id = response.authResponse.userID;
            var page_id = "40796308305"; // coca cola page https://www.facebook.com/cocacola
            var fql_query = "SELECT uid FROM page_fan WHERE page_id="+page_id+" and uid="+user_id;

            FB.api({
                method: 'fql.query',
                query: fql_query
            },
            function(response){
                if (response[0]) {
                    $("#container_like").show();
                } else {
                    $("#container_notlike").show();
                }
            }
            );    
        } else {
        // user is not logged in
        }
    });
});

I used the FB.api method (JavaScript SDK), instead of FB.Data.query, which is deprecated. Or you can use the Graph API like with this example:

$(document).ready(function() {
    FB.login(function(response) {
        if (response.status == 'connected') {
            var user_id = response.authResponse.userID;
            var page_id = "40796308305"; // coca cola page https://www.facebook.com/cocacola
            var fql_query = "SELECT uid FROM page_fan WHERE page_id=" + page_id + " and uid=" + user_id;

            FB.api('/me/likes/'+page_id, function(response) {
                if (response.data[0]) {
                    $("#container_like").show();
                } else {
                    $("#container_notlike").show();
                }
            });
        } else {
            // user is not logged in
        }
    });
});?

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

For ES6/ES2015 you can import directly like:

// example.json
{
    "name": "testing"
}


// ES6/ES2015
// app.js
import * as data from './example.json';
const {name} = data;
console.log(name); // output 'testing'

If you use Typescript, you may declare json module like:

// tying.d.ts
declare module "*.json" {
    const value: any;
    export default value;
}

Since Typescript 2.9+ you can add --resolveJsonModule compilerOptions in tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
     ...
    "resolveJsonModule": true,
     ...
  },
  ...
}

Try this:

UPDATE business AS b
INNER JOIN business_geocode AS g ON b.business_id = g.business_id
SET b.mapx = g.latitude,
  b.mapy = g.longitude
WHERE  (b.mapx = '' or b.mapx = 0) and
  g.latitude > 0

Update:

Since you said the query yielded a syntax error, I created some tables that I could test it against and confirmed that there is no syntax error in my query:

mysql> create table business (business_id int unsigned primary key auto_increment, mapx varchar(255), mapy varchar(255)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)

mysql> create table business_geocode (business_geocode_id int unsigned primary key auto_increment, business_id int unsigned not null, latitude varchar(255) not null, longitude varchar(255) not null, foreign key (business_id) references business(business_id)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)

mysql> UPDATE business AS b
    -> INNER JOIN business_geocode AS g ON b.business_id = g.business_id
    -> SET b.mapx = g.latitude,
    ->   b.mapy = g.longitude
    -> WHERE  (b.mapx = '' or b.mapx = 0) and
    ->   g.latitude > 0;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0  Changed: 0  Warnings: 0

See? No syntax error. I tested against MySQL 5.5.8.

I am posting this as an answer not because it's the correct answer to your question, but because it's a solution to the same problem, but using attributes instead. Otherwise Vikas Gujjar's answer is correct.

Quite oftern your data could be in attributes, but it's quite hard to find any working examples using XStream to do this, so here's one:

Sample data:

<settings>
    <property name="prop1" value="foo"/>
    <property name="prop2" /> <!-- NOTE:
                                   The example supports null elements as
                                   the backing object is a HashMap.
                                   A Properties object would be handled
                                   by a PropertiesConverter which wouldn't
                                   allow you null values.  -->
    <property name="prop3" value="1"/>
</settings>

Implementation of MapEntryConverter (slightly re-worked @Vikas Gujjar's implementation to use attributes instead):

public class MapEntryConverter
        implements Converter
{

    public boolean canConvert(Class clazz)
    {
        return AbstractMap.class.isAssignableFrom(clazz);
    }

    public void marshal(Object value,
                        HierarchicalStreamWriter writer,
                        MarshallingContext context)
    {

XStream instance setup, parsing and storing:

    XStream xstream = new XStream();
    xstream.autodetectAnnotations(true);
    xstream.alias("settings", HashMap.class);
    xstream.registerConverter(new MapEntryConverter());
    ...
    // Parse:
    YourObject yourObject = (YourObject) xstream.fromXML(is);
    // Store:
    xstream.toXML(yourObject);
    ...

Add this method in your view controller.

Swift:

func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
    if text == "\n" {
        textView.resignFirstResponder()
        return false
    }
    return true
}

This method also can be helpful for you:

/**
Dismiss keyboard when tapped outside the keyboard or textView

:param: touches the touches
:param: event   the related event
*/
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    if let touch = touches.anyObject() as? UITouch {
        if touch.phase == UITouchPhase.Began {
            textField?.resignFirstResponder()
        }
    }
}

Both are the same thing but many of the databases are not providing the varying char mainly postgreSQL is providing. So for the multi database like Oracle Postgre and DB2 it is good to use the Varchar

public static boolean like(String toBeCompare, String by){
    if(by != null){
        if(toBeCompare != null){
            if(by.startsWith("%") && by.endsWith("%")){
                int index = toBeCompare.toLowerCase().indexOf(by.replace("%", "").toLowerCase());
                if(index < 0){
                    return false;
                } else {
                    return true;
                }
            } else if(by.startsWith("%")){
                return toBeCompare.endsWith(by.replace("%", ""));
            } else if(by.endsWith("%")){
                return toBeCompare.startsWith(by.replace("%", ""));
            } else {
                return toBeCompare.equals(by.replace("%", ""));
            }
        } else {
            return false;
        }
    } else {
        return false;
    }
}

There are two ways to exit a method early (without quitting the program):

• Use the return keyword.
• Throw an exception.

Exceptions should only be used for exceptional circumstances - when the method cannot continue and it cannot return a reasonable value that would make sense to the caller. Usually though you should just return when you are done.

If your method returns void then you can write return without a value:

return;

Specifically about your code:

• There is no need to write the same test three times. All those conditions are equivalent.

• You should also use curly braces when you write an if statement so that it is clear which statements are inside the body of the if statement:

  if (textBox1.Text == String.Empty)
  {
      textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
  }
  return; // Are you sure you want the return to be here??
  

• If you are using .NET 4 there is a useful method that depending on your requirements you might want to consider using here: String.IsNullOrWhitespace.

• You might want to use Environment.Newline instead of "\r\n".
• You might want to consider another way to display invalid input other than writing messages to a text box.

Probably the simplest way is to use curl for this, there is no need to install any additional packages and it can be configured directly in a request.

Here is an example using gmail smtp server:

curl --url 'smtps://smtp.gmail.com:465' --ssl-reqd \
  --mail-from '[email protected]' \
  --mail-rcpt '[email protected]' \
  --user '[email protected]:YourPassword' \
  -T <(echo -e 'From: [email protected]\nTo: [email protected]\nSubject: Curl Test\n\nHello')

The onClick attribute of html tags only takes Javascript but not PHP code. However, you can easily call a PHP function from within the Javascript code by using the JS document.write() function - effectively calling the PHP function by "writing" its call to the browser window: Eg.

onclick="document.write('<?php //call a PHP function here ?>');"

Your example:

    <?php
          function hello(){
              echo "Hello";
          }
    ?>

<input type="button" name="Release" onclick="document.write('<?php hello() ?>');" value="Click to Release">

The first things popping up

EXTRACT(EPOCH FROM current_timestamp-somedate)/3600

May not be pretty, but unblocks the road. Could be prettier if division of interval by interval was defined.

Edit: if you want it greater than zero either use abs or greatest(...,0). Whichever suits your intention.

Edit++: the reason why I didn't use age is that age with a single argument, to quote the documentation: Subtract from current_date (at midnight). Meaning you don't get an accurate "age" unless running at midnight. Right now it's almost 1am here:

select age(current_timestamp);
       age        
------------------
 -00:52:40.826309
(1 row)

If the performance is an issue, you can use this command in MS_DOS:

dir /OD >d:\dir.txt

This command generate a dir.txt file in **d:** root the have all files sorted by date. And then read the file from your code. Also, you add other filters by * and ?.

You can write a function to return array of occurrence positions, Java has String.regionMatches function which is quite handy

public static ArrayList<Integer> occurrencesPos(String str, String substr) {
    final boolean ignoreCase = true;
    int substrLength = substr.length();
    int strLength = str.length();

    ArrayList<Integer> occurrenceArr = new ArrayList<Integer>();

    for(int i = 0; i < strLength - substrLength + 1; i++) {
        if(str.regionMatches(ignoreCase, i, substr, 0, substrLength))  {
            occurrenceArr.add(i);
        }
    }
    return occurrenceArr;
}

After discussion posting updated answer:

Option Explicit

    wk = ComboBox1.Value
    yr = ComboBox2.Value
    fname = yr & "W" & wk

    'Do Some Stuff

    With owb
        .SaveAs fpath & Format(Date, "yyyymm") & "DB" & ".xlsx", 51
        .Close
    End With

    With Application
        .DisplayAlerts = True

        .EnableEvents = True
    End With

Exit Sub
ErrorHandler: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then

Else: Call Clear

End Sub

Error Handling:

You could try something like this to catch a specific error:

    On Error Resume Next
    Set owb = Application.Workbooks.Open(fpath & "\" & fname)
    If Err.Number = 1004 Then
    GoTo FileNotFound
    Else
    End If

    ...
    Exit Sub
    FileNotFound: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then

    Else: Call Clear

The WebRequest object seems like too much work for me. I prefer to use the WebClient control.

To use this function you just need to create two NameValueCollections holding your parameters and request headers.

Consider the following function:

    private static string DoGET(string URL,NameValueCollection QueryStringParameters = null, NameValueCollection RequestHeaders = null)
    {
        string ResponseText = null;
        using (WebClient client = new WebClient())
        {
            try
            {
                if (RequestHeaders != null)
                {
                    if (RequestHeaders.Count > 0)
                    {
                        foreach (string header in RequestHeaders.AllKeys)
                            client.Headers.Add(header, RequestHeaders[header]);
                    }
                }
                if (QueryStringParameters != null)
                {
                    if (QueryStringParameters.Count > 0)
                    {
                        foreach (string parm in QueryStringParameters.AllKeys)
                            client.QueryString.Add(parm, QueryStringParameters[parm]);
                    }
                }
                byte[] ResponseBytes = client.DownloadData(URL);
                ResponseText = Encoding.UTF8.GetString(ResponseBytes);
            }
            catch (WebException exception)
            {
                if (exception.Response != null)
                {
                    var responseStream = exception.Response.GetResponseStream();

                    if (responseStream != null)
                    {
                        using (var reader = new StreamReader(responseStream))
                        {
                            Response.Write(reader.ReadToEnd());
                        }
                    }
                }
            }
        }
        return ResponseText;
    }

Add your querystring parameters (if required) as a NameValueCollection like so.

        NameValueCollection QueryStringParameters = new NameValueCollection();
        QueryStringParameters.Add("id", "123");
        QueryStringParameters.Add("category", "A");

Add your http headers (if required) as a NameValueCollection like so.

        NameValueCollection RequestHttpHeaders = new NameValueCollection();
        RequestHttpHeaders.Add("Authorization", "Basic bGF3c2912XBANzg5ITppc2ltCzEF");

Instead of Windows PowerShell, find the item in the Start Menu called SharePoint 2013 Management Shell:

First, don't use * in select, affects their performance and hinder the use of the group by and order by. Try this query:

SELECT wp_posts.post_author, wp_posts.post_date as pdate FROM wp_posts
WHERE wp_posts.post_status='publish'
AND wp_posts.post_type='post'
GROUP BY wp_posts.post_author           
ORDER BY pdate DESC

When you don't specifies the table in ORDER BY, just the alias, they will order the result of the select.

Basically you need to look up ArrayList element based on name getName. Two approaches to this problem:

1- Don't use ArrayList, Use HashMap<String,AutionItem> where String would be name

2- Use getName to generate index and use index based addition into array list list.add(int index, E element). One way to generate index from name would be to use its hashCode and modulo by ArrayList current size (something similar what is used inside HashMap)

Kotlin version with infix function

infix fun View.below(view: View) {
      (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.BELOW, view.id)
}

Then you can write:

view1 below view2

Or you can call it as a normal function:

view1.below(view2)

I don't know if this is still actual but problem was with Encoding. Changing to ANSI resolved the problem for me.

If you want to make sure that last row does not wrap and thus size the way you want it, have a look at

}

Some additions to a given set of answers:

First of all if you going to use Redis hash efficiently you must know a keys count max number and values max size - otherwise if they break out hash-max-ziplist-value or hash-max-ziplist-entries Redis will convert it to practically usual key/value pairs under a hood. ( see hash-max-ziplist-value, hash-max-ziplist-entries ) And breaking under a hood from a hash options IS REALLY BAD, because each usual key/value pair inside Redis use +90 bytes per pair.

It means that if you start with option two and accidentally break out of max-hash-ziplist-value you will get +90 bytes per EACH ATTRIBUTE you have inside user model! ( actually not the +90 but +70 see console output below )

 # you need me-redis and awesome-print gems to run exact code
 redis = Redis.include(MeRedis).configure( hash_max_ziplist_value: 64, hash_max_ziplist_entries: 512 ).new 
  => #<Redis client v4.0.1 for redis://127.0.0.1:6379/0> 
 > redis.flushdb
  => "OK" 
 > ap redis.info(:memory)
    {
                "used_memory" => "529512",
          **"used_memory_human" => "517.10K"**,
            ....
    }
  => nil 
 # me_set( 't:i' ... ) same as hset( 't:i/512', i % 512 ... )    
 # txt is some english fictionary book around 56K length, 
 # so we just take some random 63-symbols string from it 
 > redis.pipelined{ 10000.times{ |i| redis.me_set( "t:#{i}", txt[rand(50000), 63] ) } }; :done
 => :done 
 > ap redis.info(:memory)
  {
               "used_memory" => "1251944",
         **"used_memory_human" => "1.19M"**, # ~ 72b per key/value
            .....
  }
  > redis.flushdb
  => "OK" 
  # setting **only one value** +1 byte per hash of 512 values equal to set them all +1 byte 
  > redis.pipelined{ 10000.times{ |i| redis.me_set( "t:#{i}", txt[rand(50000), i % 512 == 0 ? 65 : 63] ) } }; :done 
  > ap redis.info(:memory)
   {
               "used_memory" => "1876064",
         "used_memory_human" => "1.79M",   # ~ 134 bytes per pair  
          ....
   }
    redis.pipelined{ 10000.times{ |i| redis.set( "t:#{i}", txt[rand(50000), 65] ) } };
    ap redis.info(:memory)
    {
             "used_memory" => "2262312",
          "used_memory_human" => "2.16M", #~155 byte per pair i.e. +90 bytes    
           ....
    }

For TheHippo answer, comments on Option one are misleading:

hgetall/hmset/hmget to the rescue if you need all fields or multiple get/set operation.

For BMiner answer.

Third option is actually really fun, for dataset with max(id) < has-max-ziplist-value this solution has O(N) complexity, because, surprise, Reddis store small hashes as array-like container of length/key/value objects!

But many times hashes contain just a few fields. When hashes are small we can instead just encode them in an O(N) data structure, like a linear array with length-prefixed key value pairs. Since we do this only when N is small, the amortized time for HGET and HSET commands is still O(1): the hash will be converted into a real hash table as soon as the number of elements it contains will grow too much

But you should not worry, you'll break hash-max-ziplist-entries very fast and there you go you are now actually at solution number 1.

Second option will most likely go to the fourth solution under a hood because as question states:

Keep in mind that if I use a hash, the value length isn't predictable. They're not all short such as the bio example above.

And as you already said: the fourth solution is the most expensive +70 byte per each attribute for sure.

My suggestion how to optimize such dataset:

You've got two options:

1. If you cannot guarantee max size of some user attributes than you go for first solution and if memory matter is crucial than compress user json before store in redis.

2. If you can force max size of all attributes. Than you can set hash-max-ziplist-entries/value and use hashes either as one hash per user representation OR as hash memory optimization from this topic of a Redis guide: https://redis.io/topics/memory-optimization and store user as json string. Either way you may also compress long user attributes.

If you want to work with $?, you'll need to check it after each command, since $? is updated after each command exits. This means that if you execute a pipeline, you'll only get the exit code of the last process in the pipeline.

Another approach is to do this:

set -e
set -o pipefail

If you put this at the top of the shell script, it looks like Bash will take care of this for you. As a previous poster noted, "set -e" will cause Bash to exit with an error on any simple command. "set -o pipefail" will cause Bash to exit with an error on any command in a pipeline as well.

See here or here for a little more discussion on this problem. Here is the Bash manual section on the set builtin.

If your base query is expected to return only one row, then you could use this trick:

select NVL( MIN(rate), 0 ) AS rate 
from d_payment_index
where fy = 2007
  and payment_year = 2008
  and program_id = 18

(Oracle code, not sure if NVL is the right function for SQL Server.)

My Theme plugin provide full featured customization for Eclipse 4. Try it. Visit Plugin Page

Looks like now they have the bat in the zip as well

note that you can use windows sc command to do more

e.g.

sc config tomcat7 start= auto

yes the space before auto is NEEDED

Another nice way to put your logic in data is something like this:

# Initialization.
CAR_TYPES = {
  foo_type: ['honda', 'acura', 'mercedes'],
  bar_type: ['toyota', 'lexus']
  # More...
}
@type_for_name = {}
CAR_TYPES.each { |type, names| names.each { |name| @type_for_name[type] = name } }

case @type_for_name[car]
when :foo_type
  # do foo things
when :bar_type
  # do bar things
end

i also want this to happen , so just pass the id of the element in the called function and used in my js file :

function copy(i,n)
{
 var range = document.createRange();
range.selectNode(document.getElementById(i));
window.getSelection().removeAllRanges();
window.getSelection().addRange(range); 
document.execCommand('copy');
window.getSelection().removeAllRanges();
document.getElementById(n).value = "Copied";
}

As an alternative, and pretty close to debiasej approach. Since a SOAP request is just a HTTP request, you can simply perform a GET or POST using with HTTP client, but it's not mandatory to build SOAP envelope.

Something like this:

using Microsoft.Extensions.Logging;
using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace HGF.Infraestructure.Communications
{
    public class SOAPSample
    {
        private readonly IHttpClientFactory _clientFactory;
        private readonly ILogger<DocumentProvider> _logger;

        public SOAPSample(ILogger<DocumentProvider> logger,
                          IHttpClientFactory clientFactory)
        {
            _clientFactory = clientFactory;
            _logger = logger;
        }

        public async Task<string> UsingGet(int value1, int value2)
        {
            try
            {
                var client = _clientFactory.CreateClient();
                var response = await client.GetAsync($"https://hostname.com/webservice.asmx/SampleMethod?value1={value1}&value2={value2}", HttpCompletionOption.ResponseHeadersRead);

                //NULL check, HTTP Status Check....

                return await response.Content.ReadAsStringAsync();
            }
            catch (Exception ex)
            {
                _logger.LogError(ex, "Oops! Something went wrong");
                return ex.Message;
            }
        }


        public async Task<string> UsingPost(int value1, int value2)
        {
            try
            {
                var content = new StringContent($"value1={value1}&value2={value2}", Encoding.UTF8, "application/x-www-form-urlencoded");

                var client = _clientFactory.CreateClient();
                var response = await client.PostAsync("https://hostname.com/webservice.asmx/SampleMethod", content);

                //NULL check, HTTP Status Check....

                return await response.Content.ReadAsStringAsync();
            }
            catch (Exception ex)
            {
                _logger.LogError(ex, "Oops! Something went wrong");
                return ex.Message;
            }
        }
    }
}

Of course, it depends on your scenario. If the payload is too complex, then this won't work

Here is how you can use Contains to achieve what you want:

buildingStatus.Select(item => item.GetCharValue()).Contains(v.Status) this will return a Boolean value.

for me anyways, it helps to see it used. just made this using the "re" example:

var analyte_data = 'sample-'+sample_id;
var storage_keys = $.jStorage.index();
var re = new RegExp( analyte_data,'g');  
for(i=0;i<storage_keys.length;i++) { 
    if(storage_keys[i].match(re)) {
        console.log(storage_keys[i]);
        var partnum = storage_keys[i].split('-')[2];
    }
}

In such a case I would recommand using the ternary operator:

child: condition ? Container() : Center()

and try to avoid code of the form:

if (condition) return A else return B

which is needlessly more verbose than the ternary operator.

But if more logic is needed you may also:

Use the Builder widget

The Builder widget is meant for allowing the use of a closure when a child widget is required:

A platonic widget that calls a closure to obtain its child widget.

It is convenient anytime you need logic to build a widget, it avoids the need to create a dedicated function.

You use the Builder widget as the child, you provide your logic in its builder method:

Center(
  child: Builder(
    builder: (context) {
      // any logic needed...
      final condition = _whateverLogicNeeded();
      
      return condition
          ? Container();
          : Center();
    }
  )
)

The Builder provides a convenient place to hold the creational logic. It is more straightforward than the immediate anonymous function proposed by atreeon.

Also I agree that the logic should be extracted from the UI code, but when it's really UI logic it is sometimes more legible to keep it there.

var BlobBuilder = (window.MozBlobBuilder || window.WebKitBlobBuilder || window.BlobBuilder);

can be used without the try catch.

Thankx to check_ca. Great work.

I'm not sure lookup is the right formula for this because of multiple arguments. Maybe hlookup or vlookup but these require you to have tables for values. A simple nested series of if does the trick for a small sample size

Try =IF(A1="a","pickup",IF(A1="b","collect",IF(A1="c","prepaid","")))

Now incorporate your left argument

=IF(LEFT(A1,1)="a","pickup",IF(LEFT(A1,1)="b","collect",IF(LEFT(A1,1)="c","prepaid","")))

Also note your usage of left, your argument doesn't specify the number of characters, but a set.

7/8/15 - Microsoft KB articles for the above mentioned functions. I don't think there's anything wrong with techonthenet, but I rather link to official sources.

• lookup
• hlookup
• vlookup
• if
• left

Setting overflow: hidden hides the scrollbar. Set overflow: scroll to make sure the scrollbar appears all the time.

To use the ::webkit-scrollbar property, simply target .scroll before calling it.

.scroll {
   width: 200px;
   height: 400px;
    background: red;
   overflow: scroll;
}
.scroll::-webkit-scrollbar {
    width: 12px;
}

.scroll::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3); 
    border-radius: 10px;
}

.scroll::-webkit-scrollbar-thumb {
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5); 
}
?

See this live example

read without any parameters will only continue if you press enter. The DOS pause command will continue if you press any key. Use read –n1 if you want this behaviour.

Note: ||= does not exist. (logical or) You can use

y= y || expr; // expr is NOT evaluated if y==true

or

y = expr ? true : y;  // expr is always evaluated.

$scope.$watch('myVar', function (newValue, oldValue) {
        if (typeof (newValue) !== 'undefined') {
            $scope.someothervar= newValue;
//or get some data
            getData();
        }


    }, true);

Variable initializes after controller so you need to watch over it and when it't initialized the use it.

The most common way of doing this is to include the binary as base-64 in an element. However, this is a workaround, and adds a bit of volume to the file.

For example, this is the bytes 00 to 09 (note we needed 16 bytes to encode 10 bytes worth of data):

<xml><image>AAECAwQFBgcICQ==</image></xml>

how you do this encoding varies per architecture. For example, with .NET you might use Convert.ToBase64String, or XmlWriter.WriteBase64.

1. First, select the form.
2. Then, go to the properties menu.

3. And change the property "FormBorderStyle" from sizable to Fixed3D or FixedSingle.

   

So the question is how can I check if my array already has a "horse" included so that I don't fill it with the same horse?

While the answers are concerned with looking through the array to see if a particular string or object exists, that's really going about it wrong, because, as the array gets larger, the search will take longer.

Instead, use either a Hash, or a Set. Both only allow a single instance of a particular element. Set will behave closer to an Array but only allows a single instance. This is a more preemptive approach which avoids duplication because of the nature of the container.

hash = {}
hash['a'] = nil
hash['b'] = nil
hash # => {"a"=>nil, "b"=>nil}
hash['a'] = nil
hash # => {"a"=>nil, "b"=>nil}

require 'set'
ary = [].to_set
ary << 'a'
ary << 'b'
ary # => #<Set: {"a", "b"}>
ary << 'a'
ary # => #<Set: {"a", "b"}>

Hash uses name/value pairs, which means the values won't be of any real use, but there seems to be a little bit of extra speed using a Hash, based on some tests.

require 'benchmark'
require 'set'

ALPHABET = ('a' .. 'z').to_a
N = 100_000
Benchmark.bm(5) do |x|
  x.report('Hash') { 
    N.times {
      h = {}
      ALPHABET.each { |i|
        h[i] = nil
      }
    }
  }

  x.report('Array') {
    N.times {
      a = Set.new
      ALPHABET.each { |i|
        a << i
      }
    }
  }
end

Which outputs:

            user     system      total        real
Hash    8.140000   0.130000   8.270000 (  8.279462)
Array  10.680000   0.120000  10.800000 ( 10.813385)

Like other said you can't use the "-" in python naming, there are many workarounds, one such workaround which would be useful if you had to add multiple modules from a path is using sys.path

For example if your structure is like this:

foo-bar
+-- barfoo.py
+-- __init__.py

import sys
sys.path.append('foo-bar')

import barfoo

You can OpenGL without a wrapper and use it natively in C#. Just as Jeff Mc said, you would have to import all the functions you need with DllImport.

What he left out is having to create context before you can use any of the OpenGL functions. It's not hard, but there are few other not-so-intuitive DllImports that need to be done.

I have created an example C# project in VS2012 with almost the bare minimum necessary to get OpenGL running on Windows box. It only paints the window blue, but it should be enough to get you started. The example can be found at http://www.glinos-labs.org/?q=programming-opengl-csharp. Look for the No Wrapper example at the bottom.

For me none of the solutions provided worked.

This should be your last resort: -> Open .iml file of your project change the LANGUAGE_LEVEL to JDK_1_8 or whatever version you wish. -> If this didn't help, you should grep "JDK" in your project root directory and find the file which contains version setting and set it to your preferred version.

var browser = navigator.appName;
var version = navigator.appVersion;

Note, however, that both will not necessarily reflect the truth. Many browsers can be set to mask as other browsers. So, for example, you can't always be sure if a user is actually surfing with IE6 or with Opera that pretends to be IE6.

NOTE: Before trying this code, please find this line in the below code:

private static String DB_NAME ="YourDbName"; // Database name

DB_NAME here is the name of your database. It is assumed that you have a copy of the database in the assets folder, so for example, if your database name is ordersDB, then the value of DB_NAME will be ordersDB,

private static String DB_NAME ="ordersDB";

Keep the database in assets folder and then follow the below:

DataHelper class:

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import android.content.Context;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

public class DataBaseHelper extends SQLiteOpenHelper {

    private static String TAG = "DataBaseHelper"; // Tag just for the LogCat window
    private static String DB_NAME ="YourDbName"; // Database name
    private static int DB_VERSION = 1; // Database version
    private final File DB_FILE;
    private SQLiteDatabase mDataBase;
    private final Context mContext;

    public DataBaseHelper(Context context) {
        super(context, DB_NAME, null, DB_VERSION);
        DB_FILE = context.getDatabasePath(DB_NAME);
        this.mContext = context;
    }

    public void createDataBase() throws IOException {
        // If the database does not exist, copy it from the assets.
        boolean mDataBaseExist = checkDataBase();
        if(!mDataBaseExist) {
            this.getReadableDatabase();
            this.close();
            try {
                // Copy the database from assests
                copyDataBase();
                Log.e(TAG, "createDatabase database created");
            } catch (IOException mIOException) {
                throw new Error("ErrorCopyingDataBase");
            }
        }
    }

    // Check that the database file exists in databases folder
    private boolean checkDataBase() {
        return DB_FILE.exists();
    }

    // Copy the database from assets
    private void copyDataBase() throws IOException {
        InputStream mInput = mContext.getAssets().open(DB_NAME);
        OutputStream mOutput = new FileOutputStream(DB_FILE);
        byte[] mBuffer = new byte[1024];
        int mLength;
        while ((mLength = mInput.read(mBuffer)) > 0) {
            mOutput.write(mBuffer, 0, mLength);
        }
        mOutput.flush();
        mOutput.close();
        mInput.close();
    }

    // Open the database, so we can query it
    public boolean openDataBase() throws SQLException {
        // Log.v("DB_PATH", DB_FILE.getAbsolutePath());
        mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.CREATE_IF_NECESSARY);
        // mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.NO_LOCALIZED_COLLATORS);
        return mDataBase != null;
    }

    @Override
    public synchronized void close() {
        if(mDataBase != null) {
            mDataBase.close();
        }
        super.close();
    }

}

Write a DataAdapter class like:

import java.io.IOException;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;

public class TestAdapter {

    protected static final String TAG = "DataAdapter";

    private final Context mContext;
    private SQLiteDatabase mDb;
    private DataBaseHelper mDbHelper;

    public TestAdapter(Context context) {
        this.mContext = context;
        mDbHelper = new DataBaseHelper(mContext);
    }

    public TestAdapter createDatabase() throws SQLException {
        try {
            mDbHelper.createDataBase();
        } catch (IOException mIOException) {
            Log.e(TAG, mIOException.toString() + "  UnableToCreateDatabase");
            throw new Error("UnableToCreateDatabase");
        }
        return this;
    }

    public TestAdapter open() throws SQLException {
        try {
            mDbHelper.openDataBase();
            mDbHelper.close();
            mDb = mDbHelper.getReadableDatabase();
        } catch (SQLException mSQLException) {
            Log.e(TAG, "open >>"+ mSQLException.toString());
            throw mSQLException;
        }
        return this;
    }

    public void close() {
        mDbHelper.close();
    }

     public Cursor getTestData() {
         try {
             String sql ="SELECT * FROM myTable";
             Cursor mCur = mDb.rawQuery(sql, null);
             if (mCur != null) {
                mCur.moveToNext();
             }
             return mCur;
         } catch (SQLException mSQLException) {
             Log.e(TAG, "getTestData >>"+ mSQLException.toString());
             throw mSQLException;
         }
     }
}

Now you can use it like:

TestAdapter mDbHelper = new TestAdapter(urContext);
mDbHelper.createDatabase();
mDbHelper.open();

Cursor testdata = mDbHelper.getTestData();

mDbHelper.close();

EDIT: Thanks to JDx

For Android 4.1 (Jelly Bean), change:

DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";

to:

DB_PATH = context.getApplicationInfo().dataDir + "/databases/";

in the DataHelper class, this code will work on Jelly Bean 4.2 multi-users.

EDIT: Instead of using hardcoded path, we can use

DB_PATH = context.getDatabasePath(DB_NAME).getAbsolutePath();

which will give us the full path to the database file and works on all Android versions

public class swaptemp {
    public static void main(String[] args) {
        String s1="10";
        String s2="20";
        String temp;
        System.out.println(s1);
        System.out.println(s2);

        temp=Integer.toString(Integer.parseInt(s1));
        s1=Integer.toString(Integer.parseInt(s2));
        s2=Integer.toString(Integer.parseInt(temp));

        System.out.println(s1);
        System.out.println(s2);
    }
}

It should be:

Class.forName(String classname)

If the leading asterisk is a problem, I pipe the git branch as follows

git branch | awk -F ' +' '! /\(no branch\)/ {print $2}'

This also eliminates the '(no branch)' line that shows up when you have detached head.

To help everyone avoid confusion, I will reformulate the question in two parts.

First : "how can make an authenticated HTTP request with a browser, using BASIC auth?".

In the browser you can do a http basic auth first by waiting the prompt to come, or by editing the URL if you follow this format: http://myusername:[email protected]

NB: the curl command mentionned in the question is perfectly fine, if you have a command-line and curl installed. ;)

References:

• https://en.wikipedia.org/wiki/Basic_access_authentication#URL_encoding
• https://en.wikipedia.org/wiki/Uniform_Resource_Locator#Syntax
• https://tools.ietf.org/html/rfc3986#page-18

Also according to the CURL manual page https://curl.haxx.se/docs/manual.html

HTTP

  Curl also supports user and password in HTTP URLs, thus you can pick a file
  like:

      curl http://name:[email protected]/full/path/to/file

  or specify user and password separately like in

      curl -u name:passwd http://machine.domain/full/path/to/file

  HTTP offers many different methods of authentication and curl supports
  several: Basic, Digest, NTLM and Negotiate (SPNEGO). Without telling which
  method to use, curl defaults to Basic. You can also ask curl to pick the
  most secure ones out of the ones that the server accepts for the given URL,
  by using --anyauth.

  NOTE! According to the URL specification, HTTP URLs can not contain a user
  and password, so that style will not work when using curl via a proxy, even
  though curl allows it at other times. When using a proxy, you _must_ use
  the -u style for user and password.

The second and real question is "However, on somesite.com, I'm not getting an authorization prompt at all, just a page that says I'm not authorized. Did somesite not implement the Basic Auth workflow correctly, or is there something else I need to do?"

The curl documentation says the -u option supports many method of authentication, Basic being the default.

Why not just leave it as a Window Forms app, and create a simple form to mimic the Console. The form can be made to look just like the black-screened Console, and have it respond directly to key press. Then, in the program.cs file, you decide whether you need to Run the main form or the ConsoleForm. For example, I use this approach to capture the command line arguments in the program.cs file. I create the ConsoleForm, initially hide it, then pass the command line strings to an AddCommand function in it, which displays the allowed commands. Finally, if the user gave the -h or -? command, I call the .Show on the ConsoleForm and when the user hits any key on it, I shut down the program. If the user doesn't give the -? command, I close the hidden ConsoleForm and Run the main form.

You need to rearrange your curly brackets. Your first statement is complete, so R interprets it as such and produces syntax errors on the other lines. Your code should look like:

if (dsnt<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else if (dst<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else {
  t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)       
} 

To put it more simply, if you have:

if(condition == TRUE) x <- TRUE
else x <- FALSE

Then R reads the first line and because it is complete, runs that in its entirety. When it gets to the next line, it goes "Else? Else what?" because it is a completely new statement. To have R interpret the else as part of the preceding if statement, you must have curly brackets to tell R that you aren't yet finished:

if(condition == TRUE) {x <- TRUE
 } else {x <- FALSE}

Try this:

{ "dt" : { "$gte" : ISODate("2013-10-01") } }

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

The above answers only work if AllowUserToAddRows is set to false. If that property is set to true, then you will get a NullReferenceException when the loop or Linq query tries to negotiate the new row. I've modified the two accepted answers above to handle AllowUserToAddRows = true.

Loop answer:

String searchValue = "somestring";
int rowIndex = -1;
foreach(DataGridViewRow row in DataGridView1.Rows)
{
    if (row.Cells["SystemId"].Value != null) // Need to check for null if new row is exposed
    {
        if(row.Cells["SystemId"].Value.ToString().Equals(searchValue))
        {
            rowIndex = row.Index;
            break;
        }
    }
}

LINQ answer:

int rowIndex = -1;

bool tempAllowUserToAddRows = dgv.AllowUserToAddRows;

dgv.AllowUserToAddRows = false; // Turn off or .Value below will throw null exception

    DataGridViewRow row = dgv.Rows
        .Cast<DataGridViewRow>()
        .Where(r => r.Cells["SystemId"].Value.ToString().Equals(searchValue))
        .First();

    rowIndex = row.Index;

dgv.AllowUserToAddRows = tempAllowUserToAddRows;

API Sanity Checker — test framework for C/C++ libraries:

An automatic generator of basic unit tests for a shared C/C++ library. It is able to generate reasonable (in most, but unfortunately not all, cases) input data for parameters and compose simple ("sanity" or "shallow"-quality) test cases for every function in the API through the analysis of declarations in header files.

The quality of generated tests allows to check absence of critical errors in simple use cases. The tool is able to build and execute generated tests and detect crashes (segfaults), aborts, all kinds of emitted signals, non-zero program return code and program hanging.

Unique features in comparison with CppUnit, Boost and Google Test:

• Automatic generation of test data and input arguments (even for complex data types)
• Modern and highly reusable specialized types instead of fixtures and templates

I love this piece of code, use it to load a file into one String:

File file = new File("/my/location");
String contents = new Scanner(file).useDelimiter("\\Z").next();

select
    email 
from loginuser where
patindex ('%[ &'',":;!+=\/()<>]*%', email) > 0  -- Invalid characters
or patindex ('[@.-_]%', email) > 0   -- Valid but cannot be starting character
or patindex ('%[@.-_]', email) > 0   -- Valid but cannot be ending character
or email not like '%@%.%'   -- Must contain at least one @ and one .
or email like '%..%'        -- Cannot have two periods in a row
or email like '%@%@%'       -- Cannot have two @ anywhere
or email like '%.@%' or email like '%@.%' -- Cant have @ and . next to each other
or email like '%.cm' or email like '%.co' -- Unlikely. Probably typos 
or email like '%.or' or email like '%.ne' -- Missing last letter

This worked for me. Had to apply rtrim and ltrim to avoid false positives.

With Java 8:

String csv = String.join(",", ids);

With Java 7-, there is a dirty way (note: it works only if you don't insert strings which contain ", " in your list) - obviously, List#toString will perform a loop to create idList but it does not appear in your code:

List<String> ids = new ArrayList<String>();
ids.add("1");
ids.add("2");
ids.add("3");
ids.add("4");
String idList = ids.toString();
String csv = idList.substring(1, idList.length() - 1).replace(", ", ",");

You should separate the host from the port number. You could have something, like:

development:
  adapter: mysql2
  encoding: utf8
  database: my_db_name
  username: root
  password: my_password
  host: 127.0.0.1
  port: 3306

I got the solution to send the JSON data by POST request through jquery ajax. I used below code

    var data = new Object();
    data.p_clientId = 4;
    data =  JSON.stringify(data);

    $.ajax({
      method: "POST",
      url: "http://192.168.1.141:8090/api/Client_Add",
      data: data,
      headers: {
        'Accept': 'application/json',
        'Content-Type': 'text/plain'
    }
    })
      .done(function( msg ) {
        alert( "Data Saved: " + msg );
      });


        });
    });

I used 'Content-Type': 'text/plain' in header to send the raw json data.
Because if we use Content-Type: 'application/json' the request methods converted to OPTION, but using Content-Type: 'test/plain' the method does not get converted and remain as POST. Hopefully this will help some one.

Check out this great tutorial on favicons and browser support.

the following code works for me in this scenario: an UIImageView forced landscape.

    imagePreview!.isUserInteractionEnabled = true
    imagePreview!.isExclusiveTouch = true
    imagePreview!.contentMode = UIView.ContentMode.scaleAspectFit
    
    // Remove all constraints
    imagePreview!.removeAllConstraints()
    
    // Add the new constraints
    let guide = view.safeAreaLayoutGuide
    imagePreview!.translatesAutoresizingMaskIntoConstraints = false
    imagePreview!.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
    imagePreview!.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
    imagePreview!.heightAnchor.constraint(equalTo: guide.heightAnchor, multiplier: 1.0).isActive = true

where removeAllConstraints is an extension

extension UIView {
    
    func removeAllConstraints() {
        var _superview = self.superview
        
        func removeAllConstraintsFromView(view: UIView) { for c in view.constraints { view.removeConstraint(c) } }
        
        while let superview = _superview {
            for constraint in superview.constraints {
                
                if let first = constraint.firstItem as? UIView, first == self {
                    superview.removeConstraint(constraint)
                }
                
                if let second = constraint.secondItem as? UIView, second == self {
                    superview.removeConstraint(constraint)
                }
            }
            
            _superview = superview.superview
        }
        
        self.removeConstraints(self.constraints)
        self.translatesAutoresizingMaskIntoConstraints = true
    }
}

Don't forget that Eclipse Platform was started by IBM. There are few platforms out there.

• IBM Websphere Application Developer (WSAD) and/or Rational Application Developer (RAD) which is a Eclipse-type IDE from IBM (actually, that's Eclipse with IBM specialized libraries/plugins).
• MyEclipse (never used it but it's another Eclipse-type IDE)
• Sun Microsystem's NetBeans. It's too Java-centric as it's designed to create applications purely in java (NetBeans runs in Java).
• IntelliJ (to name but a few)
• Oracle JDeveloper (I never really liked the directory structure layout JDeveloper creates).

The advantage with Eclipse is that it can be customized to your development pleasure, plugins can be written for Eclipse to conform to your needs (e.g. The Eclipse "Easy Explorer" plugin for browsing the directory of your source in Windows Explorer). Eclipse allows you to also incorporate other languages/SDK's, such as C++, Silverlight projects, Android Projects for development. You can also easily manage resources in Eclipse.

In my experience NetBeans are resource intensive. Oracle JDeveloper and IntelliJ aren't free though. Oh yes, If you have issues or bugs with Eclipse, Eclipse has the ability to restart and submit the crash to Eclipse servers.

A natural join is just a shortcut to avoid typing, with a presumption that the join is simple and matches fields of the same name.

SELECT
  *
FROM
  table1
NATURAL JOIN
  table2
    -- implicitly uses `room_number` to join

Is the same as...

SELECT
  *
FROM
  table1
INNER JOIN
  table2
    ON table1.room_number = table2.room_number

What you can't do with the shortcut format, however, is more complex joins...

SELECT
  *
FROM
  table1
INNER JOIN
  table2
    ON (table1.room_number = table2.room_number)
    OR (table1.room_number IS NULL AND table2.room_number IS NULL)

There is a far easier solution (IMO) in Bootstrap 3 that does not require you to compile any custom LESS. You just have to leverage the cascade in "Cascading Style Sheets."

Set up your CSS loading like so...

<link type="text/css" rel="stylesheet" href="/css/bootstrap.css" />
<link type="text/css" rel="stylesheet" href="/css/custom.css" />

Where /css/custom.css is your unique style definitions. Inside that file, add the following definition...

@media (min-width: 1200px) {
  .container {
    width: 970px;
  }
}

This will override Bootstrap's default width: 1170px setting when the viewport is 1200px or bigger.

Tested in Bootstrap 3.0.2

Using Java:

WebElement webElement = driver.findElement(By.xpath(""));//You can use xpath, ID or name whatever you like
webElement.sendKeys(Keys.TAB);
webElement.sendKeys(Keys.ENTER);

For Kotlin :

 fun getFolderName() {
            
            val uri: Uri
            val cursor: Cursor?
    
            uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI
            val projection = arrayOf(MediaStore.Audio.AudioColumns.DATA)
            cursor = requireActivity().contentResolver.query(uri, projection, null, null, null)
            if (cursor != null) {
                column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Audio.AudioColumns.DATA)
            }
            
            while (cursor!!.moveToNext()) {
    
                absolutePathOfImage = cursor.getString(column_index_data)
    
    
                val fileName: String = File(absolutePathOfImage).parentFile.name
    }
}

Swift

Short answer

Use a NotificationCenter observer rather than viewWillAppear.

override func viewDidLoad() {
    super.viewDidLoad()

    // set observer for UIApplication.willEnterForegroundNotification
    NotificationCenter.default.addObserver(self, selector: #selector(willEnterForeground), name: UIApplication.willEnterForegroundNotification, object: nil)

}

// my selector that was defined above
@objc func willEnterForeground() {
    // do stuff
}

Long answer

To find out when an app comes back from the background, use a NotificationCenter observer rather than viewWillAppear. Here is a sample project that shows which events happen when. (This is an adaptation of this Objective-C answer.)

import UIKit
class ViewController: UIViewController {

    // MARK: - Overrides

    override func viewDidLoad() {
        super.viewDidLoad()
        print("view did load")

        // add notification observers
        NotificationCenter.default.addObserver(self, selector: #selector(didBecomeActive), name: UIApplication.didBecomeActiveNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(willEnterForeground), name: UIApplication.willEnterForegroundNotification, object: nil)

    }

    override func viewWillAppear(_ animated: Bool) {
        print("view will appear")
    }

    override func viewDidAppear(_ animated: Bool) {
        print("view did appear")
    }

    // MARK: - Notification oberserver methods

    @objc func didBecomeActive() {
        print("did become active")
    }

    @objc func willEnterForeground() {
        print("will enter foreground")
    }

}

On first starting the app, the output order is:

view did load
view will appear
did become active
view did appear

After pushing the home button and then bringing the app back to the foreground, the output order is:

will enter foreground
did become active 

So if you were originally trying to use viewWillAppear then UIApplication.willEnterForegroundNotification is probably what you want.

Note

As of iOS 9 and later, you don't need to remove the observer. The documentation states:

If your app targets iOS 9.0 and later or macOS 10.11 and later, you don't need to unregister an observer in its dealloc method.

.outerdiv {
    margin-left: auto;
    margin-right: auto;
    display: table;
}

Doesn't work in internet explorer 7... but who cares ?

If you want to cut the whitespaces before and behind the word, but keep the middle ones.
You could use:

word = '  Hello World  '
stripped = word.strip()
print(stripped)

For people that have PowerShell 3 or later (i.e. Windows Server 2012+ or Windows Server 2008 R2 with the Windows Management Framework 4.0 update), you can do this one-liner instead of invoking System.Net.WebRequest:

$statusCode = wget http://stackoverflow.com/questions/20259251/ | % {$_.StatusCode}

Add this css property to the element being flickered:

-webkit-transform-style: preserve-3d;

(And a big thanks to Nathan Hoad: http://nathanhoad.net/how-to-stop-css-animation-flicker-in-webkit)

In my case, for tensorflow 2.4.0, none of the previous answer works unless you install tensorflow-cpu

pip install tensorflow-cpu

On my first attempt to Git fetch after my password change, I was told that my username/password combination was invalid. This was correct as git-credential helper had cached my old values.

However, I attempted another git fetch after restarting my terminal/command-prompt and this time the credential helper prompted me to enter in my GitHub username and password.

I suspect the initial failed Git fetch request in combination with restarting my terminal/command-prompt resolved this for me.

I hope this answer helps anybody else in a similar position in the future!

1) react-router > V5 useHistory hook:

If you have React >= 16.8 and functional components you can use the useHistory hook from react-router.

import React from 'react';
import { useHistory } from 'react-router-dom';

const YourComponent = () => {
    const history = useHistory();

    const handleClick = () => {
        history.push("/path/to/push");
    }

    return (
        <div>
            <button onClick={handleClick} type="button" />
        </div>
    );
}

export default YourComponent;

2) react-router > V4 withRouter HOC:

As @ambar mentioned in the comments, React-router has changed their code base since their V4. Here are the documentations - official, withRouter

import React, { Component } from 'react';
import { withRouter } from "react-router-dom";

class YourComponent extends Component {
    handleClick = () => {
        this.props.history.push("path/to/push");
    }

    render() {
        return (
            <div>
                <button onClick={this.handleClick} type="button">
            </div>
        );
    };
}

export default withRouter(YourComponent);

3) React-router < V4 with browserHistory

You can achieve this functionality using react-router BrowserHistory. Code below:

import React, { Component } from 'react';
import { browserHistory } from 'react-router';

export default class YourComponent extends Component {
    handleClick = () => {
        browserHistory.push('/login');
    };

    render() {
        return (
            <div>
                <button onClick={this.handleClick} type="button">
            </div>
        );
    };
}

4) Redux connected-react-router

If you have connected your component with redux, and have configured connected-react-router all you have to do is this.props.history.push("/new/url"); ie, you don't need withRouter HOC to inject history to the component props.

// reducers.js
import { combineReducers } from 'redux';
import { connectRouter } from 'connected-react-router';

export default (history) => combineReducers({
    router: connectRouter(history),
    ... // rest of your reducers
});


// configureStore.js
import { createBrowserHistory } from 'history';
import { applyMiddleware, compose, createStore } from 'redux';
import { routerMiddleware } from 'connected-react-router';
import createRootReducer from './reducers';
...
export const history = createBrowserHistory();

export default function configureStore(preloadedState) {
    const store = createStore(
        createRootReducer(history), // root reducer with router state
        preloadedState,
        compose(
            applyMiddleware(
                routerMiddleware(history), // for dispatching history actions
                // ... other middlewares ...
            ),
        ),
    );

    return store;
}


// set up other redux requirements like for eg. in index.js
import { Provider } from 'react-redux';
import { Route, Switch } from 'react-router';
import { ConnectedRouter } from 'connected-react-router';
import configureStore, { history } from './configureStore';
...
const store = configureStore(/* provide initial state if any */)

ReactDOM.render(
    <Provider store={store}>
        <ConnectedRouter history={history}>
            <> { /* your usual react-router v4/v5 routing */ }
                <Switch>
                    <Route exact path="/yourPath" component={YourComponent} />
                </Switch>
            </>
        </ConnectedRouter>
    </Provider>,
    document.getElementById('root')
);


// YourComponent.js
import React, { Component } from 'react';
import { connect } from 'react-redux';
...

class YourComponent extends Component {
    handleClick = () => {
        this.props.history.push("path/to/push");
    }

    render() {
        return (
          <div>
            <button onClick={this.handleClick} type="button">
          </div>
        );
      }
    };

}

export default connect(mapStateToProps = {}, mapDispatchToProps = {})(YourComponent);

Inspired by andrei-deusteanu answer, here is my version. This allows you to create a number of additional paths in your site-packages directory.

import os

# Add paths here.  Then Run this block of code once and restart kernel. Paths should now be set.
paths_of_directories_to_add = [r'C:\GIT\project1', r'C:\GIT\project2', r'C:\GIT\project3']

# Find your site-packages directory
pathSitePckgs = os.path.join(os.path.dirname(os.__file__), 'site-packages')

# Write a .pth file in your site-packages directory
pthFile = os.path.join(pathSitePckgs,'current_machine_paths.pth')
with open(pthFile,'w') as pth_file:
    pth_file.write('\n'.join(paths_of_directories_to_add))

print(pthFile)

Generally speaking an HTTP POST assumes the content of the body contains a series of key/value pairs that are created (most usually) by a form on the HTML side. You don't set the values using setHeader, as that won't place them in the content body.

So with your second test, the problem that you have here is that your client is not creating multiple key/value pairs, it only created one and that got mapped by default to the first argument in your method.

There are a couple of options you can use. First, you could change your method to accept only one input parameter, and then pass in a JSON string as you do in your second test. Once inside the method, you then parse the JSON string into an object that would allow access to the fields.

Another option is to define a class that represents the fields of the input types and make that the only input parameter. For example

class MyInput
{
    String str1;
    String str2;

    public MyInput() { }
      //  getters, setters
 }

@POST
@Consumes({"application/json"})
@Path("create/")
public void create(MyInput in){
System.out.println("value 1 = " + in.getStr1());
System.out.println("value 2 = " + in.getStr2());
}

Depending on the REST framework you are using it should handle the de-serialization of the JSON for you.

The last option is to construct a POST body that looks like:

str1=value1&str2=value2

then add some additional annotations to your server method:

public void create(@QueryParam("str1") String str1, 
                  @QueryParam("str2") String str2)

@QueryParam doesn't care if the field is in a form post or in the URL (like a GET query).

If you want to continue using individual arguments on the input then the key is generate the client request to provide named query parameters, either in the URL (for a GET) or in the body of the POST.

jQuery's hasClass() method returns a boolean (true/false) and not an element. Also, the parameter to be given to it is a class name and not a selector as such.

For ex: x.hasClass('error');

I don't think you should use either of the methods in the question as they're both confusing, and the second one is fragile as Mehrdad suggests.

I would advocate the following, as it looks like a standard library function and makes its intention clear:

#include <iterator>

template <class RandomIt>
void reverse_sort(RandomIt first, RandomIt last)
{
    std::sort(first, last, 
        std::greater<typename std::iterator_traits<RandomIt>::value_type>());
}

Also you can do like this:

<select class="form-control postType" ng-model="selectedProd">
    <option ng-repeat="product in productList" value="{{product}}">{{product.name}}</option>
</select>

where "selectedProd" will be selected product.

If you want to remove all the subviews on your UIView (here yourView), then write this code at your button click:

[[yourView subviews] makeObjectsPerformSelector: @selector(removeFromSuperview)];

You are looking for the __getitem__ method. See http://docs.python.org/reference/datamodel.html, section 3.4.6

They're nearly identical but bash has more features – sh is (more or less) an older subset of bash.

sh often means the original Bourne shell, which predates bash (Bourne *again* shell), and was created in 1977. But, in practice, it may be better to think of it as a highly-cross-compatible shell compliant with the POSIX standard from 1992.

Scripts that start with #!/bin/sh or use the sh shell usually do so for backwards compatibility. Any unix/linux OS will have an sh shell. On Ubuntu sh often invokes dash and on MacOS it's a special POSIX version of bash. These shells may be preferred for standard-compliant behavior, speed or backwards compatibility.

bash is newer than the original sh, adds more features, and seeks to be backwards compatible with sh. In theory, sh programs should run in bash. bash is available on nearly all linux/unix machines and usually used by default – with the notable exception of MacOS defaulting to zsh as of Catalina (10.15). FreeBSD, by default, does not come with bash installed.

Here's my solution which I derived from other posts during my own search.

This allows you to send the pp and jj output to a file as needed.

require "pp"
require "json"

class File
  def pp(*objs)
    objs.each {|obj|
      PP.pp(obj, self)
    }
    objs.size <= 1 ? objs.first : objs
  end
  def jj(*objs)
    objs.each {|obj|
      obj = JSON.parse(obj.to_json)
      self.puts JSON.pretty_generate(obj)
    }
    objs.size <= 1 ? objs.first : objs
  end
end

test_object = { :name => { first: "Christopher", last: "Mullins" }, :grades => [ "English" => "B+", "Algebra" => "A+" ] }

test_json_object = JSON.parse(test_object.to_json)

File.open("log/object_dump.txt", "w") do |file|
  file.pp(test_object)
end

File.open("log/json_dump.txt", "w") do |file|
  file.jj(test_json_object)
end

Try this code...

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>3.0-alpha-1</version>
    </dependency>

Webkit browsers support the ability to add "stroke" to fonts. This bit of style makes fonts look thinner (assuming a white background):

-webkit-text-stroke: 2px white;

Example on codepen here: http://codepen.io/mackdoyle/pen/yrgEH Some people are using SVG for a cross-platform "stroke" solution: http://codepen.io/CrocoDillon/pen/dGIsK

The problem is the padding of the font on the textview. Just add to your textview:

android:includeFontPadding="false"

The first answer is too complex, historic, and uninformative for my tastes.

It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,

• Free you from having to manually remove what you don't want, by forcing you to whitelist what you do want,
• Free resources that would otherwise be taken up because of Docker's implementation.

Let's start with the first. Very often with something like Debian you'll see.

RUN apt-get update \ 
  && apt-get dist-upgrade \
  && apt-get install <whatever> \
  && apt-get clean

We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,

RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;

It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree for an example of that).

By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean), and you would otherwise have lots of un-needed files in your final image.

See also

• Multi-stage builds
• COPY syntax

You can try like this:

var x= str== null 
        ? string.Empty 
        : str.Substring(0, Math.Min(5, str.Length));

SELECT * FROM `permlog` as one
RIGHT JOIN (SELECT MAX(id) as max_id FROM `permlog`) as two 
ON one.id = two.max_id

Let's say you generate a bunch of views that are similar. You could set an OnClickListener for each view individually:

button1.setOnClickListener(new OnClickListener ... );
button2.setOnClickListener(new OnClickListener ... );
 ...

Then you have to create a unique onClick method for each view even if they do the similar things, like:

public void onClick(View v) {
    doAction(1); // 1 for button1, 2 for button2, etc.
}

This is because onClick has only one parameter, a View, and it has to get other information from instance variables or final local variables in enclosing scopes. What we really want is to get information from the views themselves.

Enter getTag/setTag:

button1.setTag(1);
button2.setTag(2);

Now we can use the same OnClickListener for every button:

listener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        doAction(v.getTag());
    }
};

It's basically a way for views to have memories.

I also had this problem, however, right-clicking on the model.tt file and running "Custom tool" didn't make any difference for me somehow, but a comment on the page Ghlouw linked to mentioned to use the menu item "BUILD > Transform All T4 Templates." which did it for me

I had the same problem. The only thing that solved it was merge the content of META-INF/spring.handler and META-INF/spring.schemas of each spring jar file into same file names under my META-INF project.

This two threads explain it better:

• maven assembly plugin and spring namespace handlers
• Thread: unable to locate Spring NamespaceHandler for XML schema namespace

Try using below code:

<button title="button title" class="action primary tocart" onclick=" window.open('http://www.google.com', '_blank'); return false;">Google</button>

Here, the window.open with _blank as second argument of window.open function will open the link in new tab.

And by the use of return false we can remove/cancel the default behavior of the button like submit.

You can find a complete and very simple java class for sending emails using Google(gmail) account here, Send email message using java application

It uses following properties

Properties props = new Properties();
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.host", "smtp.gmail.com");
  props.put("mail.smtp.port", "587");

Another option that worked for me was to bind the network namespace of the host to the docker.

By adding:

docker run --net host

Since Java 9

As of this version, you can use a new method Matcher::results with no args that is able to comfortably return Stream<MatchResult> where MatchResult represents the result of a match operation and offers to read matched groups and more (this class is known since Java 1.5).

String string = "Some string with 'the data I want' inside and 'another data I want'.";

Pattern pattern = Pattern.compile("'(.*?)'");
pattern.matcher(string)
       .results()                       // Stream<MatchResult>
       .map(mr -> mr.group(1))          // Stream<String> - the 1st group of each result
       .forEach(System.out::println);   // print them out (or process in other way...)

The code snippet above results in:

the data I want
another data I want

The biggest advantage is in the ease of usage when one or more results is available compared to the procedural if (matcher.find()) and while (matcher.find()) checks and processing.
