The scroll speed CAN be changed, adjusted, reversed, all of the above - via javascript (or a js library such as jQuery).

WHY would you want to do this? Parallax is just one of the reasons. I have no idea why anyone would argue against doing so -- the same negative arguments can be made against hiding DIVs, sliding elements up/down, etc. Websites are always a combination of technical functionality and UX design -- a good designer can use almost any technical capability to improve UX. That is what makes him/her good.

Toni Almeida of Portugal created a brilliant demo, reproduced below:

jsFiddle Demo

HTML:

<div id="myDiv">
    Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. <span class="boldit">Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. </span>
</div>

javascript/jQuery:

  function wheel(event) {
      var delta = 0;
      if (event.wheelDelta) {(delta = event.wheelDelta / 120);}
      else if (event.detail) {(delta = -event.detail / 3);}

      handle(delta);
      if (event.preventDefault) {(event.preventDefault());}
      event.returnValue = false;
  }

  function handle(delta) {
      var time = 1000;
      var distance = 300;

      $('html, body').stop().animate({
          scrollTop: $(window).scrollTop() - (distance * delta)
      }, time );
  }

  if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false);}
    window.onmousewheel = document.onmousewheel = wheel;

How to change default scrollspeed,scrollamount,scrollinertia of a webpage

I have this solution for mobile only (tested with Android):

jQuery(function($){

zoom_level = function(){

    $("body").prepend('<div class="overlay" ' +
                'style="position:fixed; top:0%; left:0%; ' +
                'width:100%; height:100%; z-index:1;"></div>');

    var ratio = $("body .overlay:eq(0)").outerWidth() / $(window).width();
    $("body .overlay:eq(0)").remove();

    return ratio;
}

alert(zoom_level());

});

If you want the zoom level right after the pinch move, you will probably have to set a little timeout because of the rendering delay (but I'm not sure because I didn't test it).

First, what happens when T0 is not None? I would test that, then I would adjust the values I pass to plt.subplot(); maybe try values 131, 132, and 133, or values that depend whether or not T0 exists.

Second, after plt.show() is called, a new figure is created. To deal with this, you can

1. Call plt.savefig('tessstttyyy.png', dpi=100) before you call plt.show()

2. Save the figure before you show() by calling plt.gcf() for "get current figure", then you can call savefig() on this Figure object at any time.

For example:

fig1 = plt.gcf()
plt.show()
plt.draw()
fig1.savefig('tessstttyyy.png', dpi=100)

In your code, 'tesssttyyy.png' is blank because it is saving the new figure, to which nothing has been plotted.

I just want to add a non-obvious possibility not covered here. I am using @react-native-community/netinfo for detecting network changes, primarily network state. To test network-off state, the WIFI switch (on the emulator) needs to be switched off. This also effectively cuts off the bridge between the emulator and the debug environment. I had not re-enabled WIFI after my tests since i was away from the computer and promptly forgot about it when i got back.

There is a possibility that this could be the case for somebody else as well and worth checking before taking any other drastic steps.

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

The Concat method will return an object which implements IEnumerable<T> by returning an object (call it Cat) whose enumerator will attempt to use the two passed-in enumerable items (call them A and B) in sequence. If the passed-in enumerables represent sequences which will not change during the lifetime of Cat, and which can be read from without side-effects, then Cat may be used directly. Otherwise, it may be a good idea to call ToList() on Cat and use the resulting List<T> (which will represent a snapshot of the contents of A and B).

Some enumerables take a snapshot when enumeration begins, and will return data from that snapshot if the collection is modified during enumeration. If B is such an enumerable, then any change to B which occurs before Cat has reached the end of A will show up in Cat's enumeration, but changes which occur after that will not. Such semantics may likely be confusing; taking a snapshot of Cat can avoid such issues.

You can also do this as well (shorter cut) instead of having to do instance declaration. You do this in JSON instead.

class Book {
    public BookId: number;
    public Title: string;
    public Author: string;
    public Price: number;
    public Description: string;
}

var bks: Book[] = [];

 bks.push({BookId: 1, Title:"foo", Author:"foo", Price: 5, Description: "foo"});   //This is all done in JSON.

You do not need to activate the sheet (you'll take a huge performance hit for doing so, actually). Since you are declaring an object for the sheet, when you call the method starting with "wb." you are selecting that object. For example, you can jump in between workbooks without activating anything like here:

Sub Test()

Dim wb1 As Excel.Workbook
Set wb1 = Workbooks.Open("C:\Documents and Settings\xxxx\Desktop\test1.xls")
Dim wb2 As Excel.Workbook
Set wb2 = Workbooks.Open("C:\Documents and Settings\xxxx\Desktop\test2.xls")

wb1.Sheets("Sheet1").Cells(1, 1).Value = 24
wb2.Sheets("Sheet1").Cells(1, 1).Value = 24
wb1.Sheets("Sheet1").Cells(2, 1).Value = 54

End Sub

jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
jaxbMarshaller.setProperty("com.sun.xml.internal.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>");

This worked for me with JDK1.7. standalone=\"no\" can be removed to get only rest of the xml part

Another option could be using automapper: You will be converting to any type from your anonymous returned object as long public properties matches. The key points are, returning object, use linq and autommaper. (or use similar idea returning serialized json, etc. or use reflection..)

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            var data = GetData();

            var firts = data.First();

            var info = firts.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public).First(p => p.Name == "Name");
            var value = info.GetValue(firts);

            Assert.AreEqual(value, "One");
        }

        public void TestMethod2()
        {
            var data = GetData();

            var config = new MapperConfiguration(cfg => cfg.CreateMissingTypeMaps = true);
            var mapper = config.CreateMapper();

            var users = data.Select(mapper.Map<User>).ToArray();

            var firts = users.First();

            Assert.AreEqual(firts.Name, "One");

        }

        [TestMethod]

            var users = JsonConvert.DeserializeObject<User[]>(data);

            var firts = users.First();

            Assert.AreEqual(firts.Name, "One");

        }

        private object[] GetData()
        {

            return new[] { new { Id = 1, Name = "One" }, new { Id = 2, Name = "Two" } };
        }

        private string GetJData()
        {

            return JsonConvert.SerializeObject(new []{ new { Id = 1, Name = "One" }, new { Id = 2, Name = "Two" } }, Formatting.None);
        }

        public class User
        {
            public int Id { get; set; }
            public string Name { get; set; }
        }
    }

}

 $uri = $_SERVER['REQUEST_URI'];

This will give you the requested directory and file name. If you use mod_rewrite, this is extremely useful because it tells you what page the user was looking at.

If you need the actual file name, you might want to try either $_SERVER['PHP_SELF'], the magic constant __FILE__, or $_SERVER['SCRIPT_FILENAME']. The latter 2 give you the complete path (from the root of the server), rather than just the root of your website. They are useful for includes and such.

$_SERVER['PHP_SELF'] gives you the file name relative to the root of the website.

 $relative_path = $_SERVER['PHP_SELF'];
 $complete_path = __FILE__;
 $complete_path = $_SERVER['SCRIPT_FILENAME'];

The FileNameExtensionFilter class is intended for Swing to be used in a JFileChooser.

Try using a FilenameFilter instead. For example:

File dir = new File("/users/blah/dirname");
File[] files = dir.listFiles(new FilenameFilter() {
    public boolean accept(File dir, String name) {
        return name.toLowerCase().endsWith(".txt");
    }
});

127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

The number of results can (theoretically) be greater than the range of an integer. I would refactor the code and work with the returned long value instead.

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>your.company</groupId>
    <artifactId>company-parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <distributionManagement>
        <repository>
            <id>nexus-site</id>
            <url>http://central_nexus/server</url>
        </repository>
    </distributionManagement>

</project>

This can be built, released, and deployed to your local nexus so everyone has access to its artifact.

Now for all projects which you wish to use it, simply include this section:

<parent>
  <groupId>your.company</groupId>
  <artifactId>company-parent</artifactId>
  <version>1.0.0</version>
</parent>

This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.

If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.

I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.

- pom.xml (aggregator)
    - project-parent
    - project-module1
    - project-module2

What you do with this structure is include your parent module in the aggregator and build everything with a mvn install from the root directory.

We use this exact solution at my organization and it has stood the test of time and worked quite well for us.

I had same issue

I have solved by

value = self.comboBox.currentText()
print value

I had this problem too and couldn't solve it without using VBA.

In my case I had a table with numbers that I wanted to be formatted and a corresponding table next to it with the desired formatting values.

i.e. While column F contains the values I want to format, the desired formatting for each cell is captured in column Z, expressed as "RED", "AMBER" or "GREEN."

Quick solution below. Manually select the range to which to apply the conditional formatting and then run the macro.

   Sub ConditionalFormatting()
For Each Cell In Selection.Cells
With Cell
    'clean
    .FormatConditions.Delete

    'green rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""GREEN"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .Color = -11489280
        .TintAndShade = 0
    End With
    .FormatConditions(1).StopIfTrue = False

    'amber rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""AMBER"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .ThemeColor = xlThemeColorAccent6
        .TintAndShade = -0.249946592608417
    End With
    .FormatConditions(1).StopIfTrue = False

    'red rule
    .FormatConditions.Add Type:=xlExpression, Formula1:= _
        "=$Z" & Cell.Row & "=""RED"""
    .FormatConditions(.FormatConditions.Count).SetFirstPriority
    With .FormatConditions(1).Font
        .Color = -16776961
        .TintAndShade = 0
    End With
    .FormatConditions(1).StopIfTrue = False
End With

Next Cell

End Sub

Here is a trick though. You can map the Ctrl+Z keys. This can be achieved by editing the .vimrc file. Add the following lines in the '.vimrc` file.

nnoremap <c-z> :u<CR>      " Avoid using this**
inoremap <c-z> <c-o>:u<CR>

This may not the a preferred way, but can be used.

** Ctrl+Z is used in Linux to suspend the ongoing program/process.

These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default.

But if you have to send non-ASCII text or large binary data, the form-data is for that.

You can use Raw if you want to send plain text or JSON or any other kind of string. Like the name suggests, Postman sends your raw string data as it is without modifications. The type of data that you are sending can be set by using the content-type header from the drop down.

Binary can be used when you want to attach non-textual data to the request, e.g. a video/audio file, images, or any other binary data file.

Another approach (more words, less code) that may help:

The locations of local maxima and minima are also the locations of the zero crossings of the first derivative. It is generally much easier to find zero crossings than it is to directly find local maxima and minima.

Unfortunately, the first derivative tends to "amplify" noise, so when significant noise is present in the original data, the first derivative is best used only after the original data has had some degree of smoothing applied.

Since smoothing is, in the simplest sense, a low pass filter, the smoothing is often best (well, most easily) done by using a convolution kernel, and "shaping" that kernel can provide a surprising amount of feature-preserving/enhancing capability. The process of finding an optimal kernel can be automated using a variety of means, but the best may be simple brute force (plenty fast for finding small kernels). A good kernel will (as intended) massively distort the original data, but it will NOT affect the location of the peaks/valleys of interest.

Fortunately, quite often a suitable kernel can be created via a simple SWAG ("educated guess"). The width of the smoothing kernel should be a little wider than the widest expected "interesting" peak in the original data, and its shape will resemble that peak (a single-scaled wavelet). For mean-preserving kernels (what any good smoothing filter should be) the sum of the kernel elements should be precisely equal to 1.00, and the kernel should be symmetric about its center (meaning it will have an odd number of elements.

Given an optimal smoothing kernel (or a small number of kernels optimized for different data content), the degree of smoothing becomes a scaling factor for (the "gain" of) the convolution kernel.

Determining the "correct" (optimal) degree of smoothing (convolution kernel gain) can even be automated: Compare the standard deviation of the first derivative data with the standard deviation of the smoothed data. How the ratio of the two standard deviations changes with changes in the degree of smoothing cam be used to predict effective smoothing values. A few manual data runs (that are truly representative) should be all that's needed.

All the prior solutions posted above compute the first derivative, but they don't treat it as a statistical measure, nor do the above solutions attempt to performing feature preserving/enhancing smoothing (to help subtle peaks "leap above" the noise).

Finally, the bad news: Finding "real" peaks becomes a royal pain when the noise also has features that look like real peaks (overlapping bandwidth). The next more-complex solution is generally to use a longer convolution kernel (a "wider kernel aperture") that takes into account the relationship between adjacent "real" peaks (such as minimum or maximum rates for peak occurrence), or to use multiple convolution passes using kernels having different widths (but only if it is faster: it is a fundamental mathematical truth that linear convolutions performed in sequence can always be convolved together into a single convolution). But it is often far easier to first find a sequence of useful kernels (of varying widths) and convolve them together than it is to directly find the final kernel in a single step.

Hopefully this provides enough info to let Google (and perhaps a good stats text) fill in the gaps. I really wish I had the time to provide a worked example, or a link to one. If anyone comes across one online, please post it here!

The problem with your solution is that it does not work well when tied down to other directives that creates a new scope, e.g. ng-repeat. A better solution would be to simply create a service function that enables you to focus elements imperatively within your controllers or to focus elements declaratively in the html.

DEMO

JAVASCRIPT

Service

 .factory('focus', function($timeout, $window) {
    return function(id) {
      // timeout makes sure that it is invoked after any other event has been triggered.
      // e.g. click events that need to run before the focus or
      // inputs elements that are in a disabled state but are enabled when those events
      // are triggered.
      $timeout(function() {
        var element = $window.document.getElementById(id);
        if(element)
          element.focus();
      });
    };
  });

Directive

  .directive('eventFocus', function(focus) {
    return function(scope, elem, attr) {
      elem.on(attr.eventFocus, function() {
        focus(attr.eventFocusId);
      });

      // Removes bound events in the element itself
      // when the scope is destroyed
      scope.$on('$destroy', function() {
        elem.off(attr.eventFocus);
      });
    };
  });

Controller

.controller('Ctrl', function($scope, focus) {
    $scope.doSomething = function() {
      // do something awesome
      focus('email');
    };
  });

HTML

<input type="email" id="email" class="form-control">
<button event-focus="click" event-focus-id="email">Declarative Focus</button>
<button ng-click="doSomething()">Imperative Focus</button>

Try this

padding:8px;
overflow: hidden;
zoom: 1;
text-align: left;
font-size: 13px;
font-family: "Trebuchet MS",Arial,Sans;
line-height: 24px;
color: black;
border-bottom: solid 1px #BBB;
background:url('images/checked.gif') white no-repeat;

This is full css.. Why you use padding:0 8px, then override it with paddings? This is what you need...

• Using "BATCH DRAWABLE IMPORT" feature you can import custom size depending upon your requirement example 20dp*20dp

  • Now after importing use the imported drawable_image as drawable_source for your button

  • It's simpler this way

Put your if condition inside resize function:

var windowsize = $(window).width();

$(window).resize(function() {
  windowsize = $(window).width();
  if (windowsize > 440) {
    //if the window is greater than 440px wide then turn on jScrollPane..
      $('#pane1').jScrollPane({
         scrollbarWidth:15, 
         scrollbarMargin:52
      });
  }
});

<select id="myselect">
    <option value="0">sometext</option>
    <option value="2">Ready for Review</option>
    <option value="3">Registration Date</option>
</select>

$('#myselect').change(function() {
    if($('#myselect option:selected').val() == 0) {
    ...
    }
    else {
    ...
    }
});

this is the way, but i would suggest to write a getter and setter for that variable.

class Testclass

{
    private $testvar = "default value";

    public function setTestvar($testvar) { 
        $this->testvar = $testvar; 
    }
    public function getTestvar() { 
        return $this->testvar; 
    }

    function dosomething()
    {
        echo $this->getTestvar();
    }
}

$Testclass = new Testclass();

$Testclass->setTestvar("another value");

$Testclass->dosomething();

As indicated here https://stackoverflow.com/a/1632004/330867, you can implement it by "filtering" what is originating the exit of this page.

As mentionned in the comments, here's a new version of the code in the other question, which also include the ajax request you make in your question :

var canExit = true;

// For every function that will call an ajax query, you need to set the var "canExit" to false, then set it to false once the ajax is finished.

function checkCart() {
  canExit = false;
  $.ajax({
    url : 'index.php?route=module/cart/check',
    type : 'POST',
    dataType : 'json',
    success : function (result) {
       if (result) {
        canExit = true;
       }
    }
  })
}

$(document).on('click', 'a', function() {canExit = true;}); // can exit if it's a link
$(window).on('beforeunload', function() {
    if (canExit) return null; // null will allow exit without a question
    // Else, just return the message you want to display
    return "Do you really want to close?";
});

Important: You shouldn't have a global variable defined (here canExit), this is here for simpler version.

Note that you can't override completely the confirm message (at least in chrome). The message you return will only be prepended to the one given by Chrome. Here's the reason : How can I override the OnBeforeUnload dialog and replace it with my own?

In Windows systems, use the command csc <filname>.cs in the command prompt while the current directory is in Microsoft Visual Studio\<Year>\<Version>

There are two ways:

Using the command prompt:

1. Start --> Command Prompt
2. Change the directory to Visual Studio folder, using the command: cd C:\Program Files (x86)\Microsoft Visual Studio\2017\ <Version>
3. Use the command: csc /.cs

Using Developer Command Prompt :

1. Start --> Developer Command Prompt for VS 2017 (Here the directory is already set to Visual Studio folder)

2. Use the command: csc /.cs

Hope it helps!

xml was not in the WEB-INF folder, thats why i was getting this error, make sure that web.xml and xxx-servlet.xml is inside WEB_INF folder and not in the webapp folder .

I used something like this to type only values in my SQL request. There are too much columns in my case, and im lazy.

insert into my_table select max(id)+1, valueA, valueB, valueC.... from my_table; 

After trying and reading carefully, I solved it myself. Solution is to add the following line in build.gradle.

flavorDimensions "versionCode"

android { 
       compileSdkVersion 24
       .....
       flavorDimensions "versionCode"
} 

You can have a look at Jansson

The website states the following: Jansson is a C library for encoding, decoding and manipulating JSON data. It features:

• Simple and intuitive API and data model
• Can both encode to and decode from JSON
• Comprehensive documentation
• No dependencies on other libraries
• Full Unicode support (UTF-8)
• Extensive test suite

It's not that much work to make a function that's allocating the needed memory for your string. That's a little c-function i wrote some time ago, i always use it to read in strings.

It will return the read string or if a memory error occurs NULL. But be aware that you have to free() your string and always check for it's return value.

#define BUFFER 32

char *readString()
{
    char *str = malloc(sizeof(char) * BUFFER), *err;
    int pos;
    for(pos = 0; str != NULL && (str[pos] = getchar()) != '\n'; pos++)
    {
        if(pos % BUFFER == BUFFER - 1)
        {
            if((err = realloc(str, sizeof(char) * (BUFFER + pos + 1))) == NULL)
                free(str);
            str = err;
        }
    }
    if(str != NULL)
        str[pos] = '\0';
    return str;
}

This works with multiple statements:

if condition1 Then stmt1:stmt2 Else if condition2 Then stmt3:stmt4 Else stmt5:stmt6

Or you can split it over multiple lines:

if condition1 Then stmt1:stmt2
Else if condition2 Then stmt3:stmt4
Else stmt5:stmt6

you can simply do that by using below single line of code

val arr = df.select("column").collect()(99)

I had the same problem, but it was because in my buttons layout_width/height I forgot to put dp at the end when editing them. Added dp and problem fixed :/

Now (2020) NetBeans 11 does it automatically with the "Build" command (right click on the project's name and choose "Build")

"I actually tried to had a normal objective discusssion over pros and cons of 1., using framework over pure javascript and 2., jquery vs. others, since jQuery seems to be easiest to work with with quickest learning curve."

Using any framework because you don't want to actually learn the underlying language is absolutely wrong not only for JavaScript, but for any other programming language.

"Is there any reason (besides browser sniffing and personal "hate" against John Resig) why jQuery is wrong?"

Most of the hate agains it comes from the exaggerated fanboyism which pollutes forums with "use jQuery" as an answer for every single JavaScript question and the overuse which produces code in which simple statements such as declaring a variable are done through library calls.

Nevertheless, there are also some legit technical issues such as the shared guilt in producing illegible code and overhead. Of course those two are aggravated by the lack of developer proficiency rather than the library itself.

I try to sort data with query it working fine for me please try this:

select name from user order by name asc 

Also try below query for search record by alphabetically

SELECT name  FROM `user` WHERE `name` LIKE 'b%' 

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

for an android screen you can use this property elevation.

for example :

 HeaderView:{
    backgroundColor:'#F8F8F8',
    justifyContent:'center',
    alignItems:'center',
    height:60,
    paddingTop:15,

    //Its for IOS
    shadowColor: '#000',
    shadowOffset: { width: 0, height: 2 },
    shadowOpacity: 0.2,

    // its for android 
    elevation: 5,
    position:'relative',

},

You can do exactly the same thing in R with two more characters:

x <- 0:9
x[-5:-1]
[1] 5 6 7 8 9

or

x[-(1:5)]

Subscribing to the IUS Community Project Repository

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }
        }
    }
    return promo;
}

For Any String try this:

string s = Console.ReadLine();
foreach( char c in s)
{
    Console.WriteLine(System.Convert.ToInt32(c));
}
Console.ReadKey();

Use this:

listBox1.Items.Clear();

You can disable need to run Internet Explorer's first launch configuration by running this PowerShell script, it will adjust corresponding registry property:

Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Internet Explorer\Main" -Name "DisableFirstRunCustomize" -Value 2

After this, WebClient will work without problems

$(document).ready(function() {
    $('ul.art-vmenu li').live("click", function() {
        alert($(this).text());
    });

jquery documentation on live(): http://api.jquery.com/live/

Description: Attach a handler to the event for all elements which match the current selector, now and in the future.

If you need to interact directly with the DOM element, why not just use document.getElementById since, if you are trying to interact with a specific element you will probably know the id, as assuming that the classname is on only one element or some other option tends to be risky.

But, I tend to agree with the others, that in most cases you should learn to do what you need using what jQuery gives you, as it is very flexible.

UPDATE: Based on a comment: Here is a post with a nice explanation: http://www.mail-archive.com/[email protected]/msg04461.html

$(this).attr("checked") ? $(this).val() : 0

This will return the value if it's checked, or 0 if it's not.

$(this).val() is just reaching into the dom and getting the attribute "value" of the element, whether or not it's checked.

HTML:

<div  ng-repeat="scannedDevice in ScanResult">
        <!--GridStarts-->
          <div >
              <img ng-src={{'./assets/img/PlaceHolder/Test.png'}} 
                   <!--Pass Param-->
                   ng-click="connectDevice(scannedDevice.id)"
                   altSrc="{{'./assets/img/PlaceHolder/user_place_holder.png'}}" 
                   onerror="this.src = $(this).attr('altSrc')">
           </div>    
 </div>

Java Script:

   //Global Variables
    var  ANGULAR_APP = angular.module('TestApp',[]);

    ANGULAR_APP .controller('TestCtrl',['$scope', function($scope) {

      //Variables
      $scope.ScanResult = [];

      //Pass Parameter
      $scope.connectDevice = function(deviceID) {
            alert("Connecting : "+deviceID );
        };
     }]);

It works. Thanks to all of you. :)

The first version will add a new KeyValuePair to the dictionary, throwing if key is already in the dictionary. The second, using the indexer, will add a new pair if the key doesn't exist, but overwrite the value of the key if it already exists in the dictionary.

IDictionary<string, string> strings = new Dictionary<string, string>();

strings["foo"] = "bar";          //strings["foo"] == "bar"
strings["foo"] = string.Empty;   //strings["foo"] == string.empty
strings.Add("foo", "bar");       //throws

A good example of using the Generic Repository pattern and implementing a generic solution for this might look something like this.

public IList<TEntity> Get<TParamater>(IList<Expression<Func<TEntity, TParamater>>> includeProperties)

{

    foreach (var include in includeProperties)
     {

        query = query.Include(include);
     }

        return query.ToList();
}

Filezilla is great and it can support command line arguments.

You should check your designer file. Open Form1.Designer.cs and
find this line: windows Form Designer Generated Code.
Expand this and you will see a lot of code. So check Whether this line is there inside datagridview1 controls if not place it.

this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick); 

I hope it helps.

To install the 3rd party jar which is not in maven repository use maven-install-plugin.

Below are steps:

1. Download the jar file manually from the source (website)
2. Create a folder and place your jar file in it
3. Run the below command to install the 3rd party jar in your local maven repository

mvn install:install-file -Dfile= -DgroupId= -DartifactId= -Dversion= -Dpackaging=

Below is the e.g one I used it for simonsite log4j

mvn install:install-file -Dfile=/Users/athanka/git/MyProject/repo/log4j-rolling-appender.jar -DgroupId=uk.org.simonsite -DartifactId=log4j-rolling-appender -Dversion=20150607-2059 -Dpackaging=jar

4. In the pom.xml include the dependency as below

     <dependency> 
           <groupId>uk.org.simonsite</groupId>
           <artifactId>log4j-rolling-appender</artifactId>
           <version>20150607-2059</version> 
     </dependency>
   

5. Run the mvn clean install command to create your packaging

Below is the reference link:

https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html

You're nearly there, just take out the EXECUTE:

Indexers (C# Programming Guide)

class SampleCollection<T>
{
    private T[] arr = new T[100];
    public T this[int i]
    {
        get => arr[i];
        set => arr[i] = value;
    }
}

// This class shows how client code uses the indexer
class Program
{
    static void Main(string[] args)
    {
        SampleCollection<string> stringCollection = 
            new SampleCollection<string>();
        stringCollection[0] = "Hello, World";
        System.Console.WriteLine(stringCollection[0]);

Here is a tidyverse option that might work depending on the data, and some caveats on its usage:

library(tidyverse)

starting_df %>% 
  rownames_to_column() %>% 
  gather(variable, value, -rowname) %>% 
  spread(rowname, value)

rownames_to_column() is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column() and replace rowname with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths sample data would be:

smiths %>% 
    gather(variable, value, -subject) %>% 
    spread(subject, value)

Using the example starting_df with the tidyverse approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths data will not give that warning because all columns except for subject are doubles.

The earlier answer using as.data.frame(t()) will convert everything to a factor if there are mixed column types unless stringsAsFactors = FALSE is added, whereas the tidyverse option converts everything to a character by default if there are mixed column types.

1. Go to Software Center and remove "IDLE(using Python-2.7)".

2. Install "IDLE(using Python-3.4)".

Gson is also good for it: http://code.google.com/p/google-gson/

" Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of. "

If you're on Linux, seriously consider just using the g_file_get_contents function from glib. It handles all the code for loading a file, allocating memory, and handling errors.

@(new HtmlString(myString))

When you use VARIABLE = value, if value is actually a reference to another variable, then the value is only determined when VARIABLE is used. This is best illustrated with an example:

VAL = foo
VARIABLE = $(VAL)
VAL = bar

# VARIABLE and VAL will both evaluate to "bar"

When you use VARIABLE := value, you get the value of value as it is now. For example:

VAL = foo
VARIABLE := $(VAL)
VAL = bar

# VAL will evaluate to "bar", but VARIABLE will evaluate to "foo"

Using VARIABLE ?= val means that you only set the value of VARIABLE if VARIABLE is not set already. If it's not set already, the setting of the value is deferred until VARIABLE is used (as in example 1).

VARIABLE += value just appends value to VARIABLE. The actual value of value is determined as it was when it was initially set, using either = or :=.

For Swift:

AVPlayer:

let player = AVPlayer(URL: NSURL(string: "http://www.sample.com/movie.mov"))
if (player.rate != 0 && player.error == nil) {
   println("playing")
}

Update:
player.rate > 0 condition changed to player.rate != 0 because if video is playing in reverse it can be negative thanks to Julian for pointing out.
Note: This might look same as above(Maz's) answer but in Swift '!player.error' was giving me a compiler error so you have to check for error using 'player.error == nil' in Swift.(because error property is not of 'Bool' type)

AVAudioPlayer:

if let theAudioPlayer =  appDelegate.audioPlayer {
   if (theAudioPlayer.playing) {
       // playing
   }
}

AVQueuePlayer:

if let theAudioQueuePlayer =  appDelegate.audioPlayerQueue {
   if (theAudioQueuePlayer.rate != 0 && theAudioQueuePlayer.error == nil) {
       // playing
   }
}

localStorage.clear();

or

window.localStorage.clear();

to clear particular item

window.localStorage.removeItem("item_name");

To remove particular value by id :

var item_detail = JSON.parse(localStorage.getItem("key_name")) || [];           
            $.each(item_detail, function(index, obj){
                if (key_id == data('key')) {
                    item_detail.splice(index,1);
                    localStorage["key_name"] = JSON.stringify(item_detail);
                    return false;
                }
            });

Create a Windows Forms Application, and change the output type to Console.

It will result in both a console and the form to open.

A small refinement of Kyle Burton's answer with improved output formatting:

#!/bin/bash
for user in $(cut -f1 -d: /etc/passwd)
do echo $user && crontab -u $user -l
echo " "
done

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

The answer from Shivam Kotwalia works perfectly. However, the object is imported as a byte type. Sometimes you may need it as a string for performing REGEX or something like that.

I recommend the following code (two lines from Shivam Kotwalia's answer) :

import textract

text = textract.process("path/to/file.extension")
text = text.decode("utf-8") 

The last line will convert the object text to a string.

I had same problem and i find out solution by following this guide . I run with goal in maven.

clean package

Its worked for me Thanq

You can pass "<>" (including the quotes) as the parameter for criteria. This basically says, as long as its not empty/blank, count it. I believe this is what you want.

=COUNTIF(A1:A10, "<>") 

Otherwise you can use CountA as Scott suggests

In a nutshell it means.. You are trying to access an object without instantiating it.. You might need to use the "new" keyword to instantiate it first i.e create an instance of it.

For eg:

public class MyClass
{
   public int Id {get; set;}
}

MyClass myClass;

myClass.Id = 0; <----------- An error will be thrown here.. because myClass is null here...

You will have to use:

myClass = new MyClass();
myClass.Id = 0;

Hope I made it clear..

Assuming there are no prepending/succeeding whitespace characters, there are still a few ways to assert string equality. Some of those are:

• strings.ToLower(..) then ==
• strings.EqualFold(.., ..)
• cases#Lower paired with ==
• cases#Fold paired with ==

Here are some basic benchmark results (in these tests, strings.EqualFold(.., ..) seems like the most performant choice):

None of these answers with the use of HEAD@{1} worked out for me, so here's my solution:

git reflog

d0c9f22 HEAD@{0}: commit (amend): [Feature] - ABC Commit Description 
c296452 HEAD@{1}: commit: [Feature] - ABC Commit Description 

git reset --soft c296452

Your staging environment will now contain all of the changes that you accidentally merged with the c296452 commit.

This stems from the fact that on deletion, the iteration skips one element as it semms only to work on the index.

Workaround could be:

x = ["ok", "jj", "uy", "poooo", "fren"]
for item in x[:]: # make a copy of x
    if len(item) != 2:
        print "length of %s is: %s" %(item, len(item))
        x.remove(item)

As of python 3.5.2, you can use:

class C(B):
def method(self, arg):
    super().method(arg)    # This does the same thing as:
                           # super(C, self).method(arg)

https://docs.python.org/3/library/functions.html#super

One obvious thing is that you will have to remove the comma here

receipt int(10),

but the actual problem is because of the line

amount double(10) NOT NULL,

change it to

amount double NOT NULL,

function foo(Array $array)
{
     return $array;
}

The best solution would be to go to http://projects.eclipse.org/projects/tools.pdt/downloads where you will find the URL to the most updated PDT, as most of the URLS listed above are hitting a 404. Then pasting the URL to eclipse.

Yes, although it's full of gotchas, since JPA is a bit peculiar. It's very much worth reading the documentation on injecting JPA EntityManager and EntityManagerFactory, without explicit Spring dependencies in your code:

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-jpa

This allows you to either inject the EntityManagerFactory, or else inject a thread-safe, transactional proxy of an EntityManager directly. The latter makes for simpler code, but means more Spring plumbing is required.

That's what ln is documented to do when the target already exists and is a directory. If you want /etc/nginx to be a symlink rather than contain a symlink, you had better not create it as a directory first!

Its a big confusion for the people who started working on python and the answers here are a little difficult to comprehend so i'll make it easier.

When we instruct Python to run our script, there are a few steps that Python carries out before our code actually starts crunching away:

• It is compiled to bytecode.
• Then it is routed to virtual machine.

When we execute a source code, Python compiles it into a byte code. Compilation is a translation step, and the byte code is a low-level platform-independent representation of source code. Note that the Python byte code is not binary machine code (e.g., instructions for an Intel chip).

Actually, Python translate each statement of the source code into byte code instructions by decomposing them into individual steps. The byte code translation is performed to speed execution. Byte code can be run much more quickly than the original source code statements. It has.pyc extension and it will be written if it can write to our machine.

So, next time we run the same program, Python will load the .pyc file and skip the compilation step unless it's been changed. Python automatically checks the timestamps of source and byte code files to know when it must recompile. If we resave the source code, byte code is automatically created again the next time the program is run.

If Python cannot write the byte code files to our machine, our program still works. The byte code is generated in memory and simply discarded on program exit. But because .pyc files speed startup time, we may want to make sure it has been written for larger programs.

Let's summarize what happens behind the scenes. When a Python executes a program, Python reads the .py into memory, and parses it in order to get a bytecode, then goes on to execute. For each module that is imported by the program, Python first checks to see whether there is a precompiled bytecode version, in a .pyo or .pyc, that has a timestamp which corresponds to its .py file. Python uses the bytecode version if any. Otherwise, it parses the module's .py file, saves it into a .pyc file, and uses the bytecode it just created.

Byte code files are also one way of shipping Python codes. Python will still run a program if all it can find are.pyc files, even if the original .py source files are not there.

Python Virtual Machine (PVM)

Once our program has been compiled into byte code, it is shipped off for execution to Python Virtual Machine (PVM). The PVM is not a separate program. It need not be installed by itself. Actually, the PVM is just a big loop that iterates through our byte code instruction, one by one, to carry out their operations. The PVM is the runtime engine of Python. It's always present as part of the Python system. It's the component that truly runs our scripts. Technically it's just the last step of what is called the Python interpreter.

Beside the quite obvious reason (IIS), there is another reason that is common enough for this problem. It is worth to quote this question and its answer here:

http://stackoverflow.com/questions/22994888/why-skype-using-http-or-https-ports-80-and-443 

So, if you have Skype installed in the computer, be sure to check this as well. The solution is quoted here:

To turn off and disable Skype usage of and listening on port 80 and port 443, open the Skype window, then click on Tools menu and select Options. Click on Advanced tab, and go to Connection sub-tab. Untick or uncheck the check box for Use port 80 and 443 as an alternatives for incoming connections option. Click on Save button and then restart Skype to make the change effective.

For python3.5.3, pip3 is also installed when you install python. When you install it you may not select the add to path. Then you can find where the pip3 located and add it to path manually.

So I just had to solve this very problem, and none of the previous answers worked for me out of the box. My situation: a UISearchBar, plus a number of other controls on the screen. I want for a tap outside of the search bar to dismiss the keyboard, but not propagate to any of the other controls. When the keyboard is hidden, I want all the controls to work.

What I did:

1) Implement a custom touch handler in my view controller.

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?)
{
    if searchBar.isFirstResponder()
    {
        // This causes the first responder, whoever it is, to resign first responder, and hide the keyboard.
        // We also "eat" the touch here and not allow it to propagate further.
        view.endEditing(true)
    }
    else
    {
        // OK to propagate the touch
        super.touchesBegan(touches, withEvent: event)
    }
}

2) Added a couple of delegate methods (mine are for the UISearchBar, but there are similar ones for UITextField). controlContainerView in the code below is a UIView that has a bunch of buttons in it. Remember that setting userInteractionEnabled on a superview disables all its subviews.

 func searchBarTextDidBeginEditing(searchBar: UISearchBar)
 {
     controlContainerView.userInteractionEnabled = false
     someButton.userInteractionEnabled = false
 }

 func searchBarTextDidEndEditing(searchBar: UISearchBar)
 {
     searchBar.resignFirstResponder()

    // Done editing: enable the other controls again.

    controlContainerView.userInteractionEnabled = false
    someButton.userInteractionEnabled = false
}

Putting the model dot property in strings worked for me: ModelState.AddModelError("Item1.Month", "This is not a valid date");

I found this somewhere else. I like this answer!

SELECT [Hourly], COUNT(*) as [Count]
  FROM 
 (SELECT dateadd(hh, datediff(hh, '20010101', [date_created]), '20010101') as [Hourly]
    FROM table) idat
 GROUP BY [Hourly]

I will give you steps to writing and compiling code. Use this example:

 public class Paycheck {
    public static void main(String args[]) {
        double amountInAccount;
        amountInAccount = 128.57;
        System.out.print("You earned $");
        System.out.print(amountInAccount);
        System.out.println(" at work today.");
    }
}

1. Save the code as Paycheck.java
2. Go to terminal and type cd Desktop
3. Type javac Paycheck.java
4. Type java Paycheck
5. Enjoy your program!

in keyword allows you to loop over a collection and check if there is a member in the collection that is equal to the element.

In this case string is nothing but a list of characters:

dog = "xdasds"
if "x" in dog:
     print "Yes!"

You can check a substring too:

>>> 'x' in "xdasds"
True
>>> 'xd' in "xdasds"
True
>>> 
>>> 
>>> 'xa' in "xdasds"
False

Think collection:

>>> 'x' in ['x', 'd', 'a', 's', 'd', 's']
True
>>> 

You can also test the set membership over user defined classes.

For user-defined classes which define the __contains__ method, x in y is true if and only if y.__contains__(x) is true.

If you got this problem in Visual Studio 2017, chances are you're working with an MVC 4 project created in a previous version of VS with a reference hint path pointing to C:\Program Files (x86)\Microsoft ASP.NET. Visual Studio 2017 does not install this directory anymore.

We usually solve this by installing a copy of Visual Studio 2015 alongside our 2017 instance, and that installs the necessary libraries in the above path. Then we update all the references in the affected projects and we're good to go.

First, you need the permission in your AndroidManifest.xml:

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

Also, in yourAndroidManifest.xml, define your service and listen for the BOOT_COMPLETED action:

<service android:name=".MyService" android:label="My Service">
    <intent-filter>
        <action android:name="com.myapp.MyService" />
    </intent-filter>
</service>

<receiver
    android:name=".receiver.StartMyServiceAtBootReceiver"
    android:label="StartMyServiceAtBootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Then you need to define the receiver that will get the BOOT_COMPLETED action and start your service.

public class StartMyServiceAtBootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            Intent serviceIntent = new Intent(context, MyService.class);
            context.startService(serviceIntent);
        }
    }
}

And now your service should be running when the phone starts up.

Any of the above.

Short and simple differences between Tcp and Udp protocol:

1) Tcp - Transmission control protocol and Udp - User datagram protocol.

2) Tcp is reliable protocol, Where as Udp is a unreliable protocol.

3) Tcp is a stream oriented, where as Udp is a message oriented protocol.

4) Tcp is a slower than Udp.

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

My answer is based on getting a 403 error although I had all of the Apache settings mentioned in the other answers correct.

It was a fresh Centos 7 server and it turned out that the issue was not the Apache settings but the fact that the PhpMyAdmin did not serve at all. The solution was to install php and add the php directive to apache.conf:

• sudo yum install php php-mysql
• vim /etc/httpd/conf/httpd.conf add something like
• DirectoryIndex index.php index.phtml index.html index.htm to serve php index files also and then restart apache

Don't forget to restart Apache server to take effect - systemctl restart httpd.service

I hope this helps. I first thought my issue was Apache directives, so I post my solution here.

public void paintComponent(Graphics g) {
   super.paintComponent(g);
   Graphics2D g2d = (Graphics2D)g;
   // Assume x, y, and diameter are instance variables.
   Ellipse2D.Double circle = new Ellipse2D.Double(x, y, diameter, diameter);
   g2d.fill(circle);
   ...
}

Here are some docs about paintComponent (link).

You should override that method in your JPanel and do something similar to the code snippet above.

In your ActionListener you should specify x, y, diameter and call repaint().

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

You can use the VisibleChanged event handler.

private void DataGridView1_VisibleChanged(object sender, System.EventArgs e)
{
    var grid = sender as DataGridView;
    grid.Rows[0].Cells[0].Style.BackColor = Color.Yellow;
}

if you do not want to delete all NaN, use

df[~df.C.str.contains("XYZ") == True]

ResultSet rs = ps.executeQuery();
int rowcount = 0;
if (rs.last()) {
  rowcount = rs.getRow();
  rs.beforeFirst(); // not rs.first() because the rs.next() below will move on, missing the first element
}
while (rs.next()) {
  // do your standard per row stuff
}

It's easier with the enumitem package:

\documentclass{article}
\usepackage{enumitem}
\begin{document}
Less space:
\begin{itemize}[noitemsep]
  \item foo
  \item bar
  \item baz
\end{itemize}

Even more compact:
\begin{itemize}[noitemsep,nolistsep]
  \item foo
  \item bar
  \item baz
\end{itemize}
\end{document}

The enumitem package provides a lot of features to customize bullets, numbering and lengths.

The paralist package provides very compact lists: compactitem, compactenum and even lists within paragraphs like inparaenum and inparaitem.

This happened to me when I was already using @Transactional(value=...) and was using multiple transaction managers.

My forms were sending back data that already had @JsonIgnore on them, so the data being sent back from forms was incomplete.

Originally I used the anti pattern solution, but found it was incredibly slow. I disabled this by setting it to false.

spring.jpa.properties.hibernate.enable_lazy_load_no_trans=false

The fix was to ensure that any objects that had lazy-loaded data that weren't loading were retrieved from the database first.

Optional<Object> objectDBOpt = objectRepository.findById(object.getId());

if (objectDBOpt.isEmpty()) {
    // Throw error
} else {
    Object objectFromDB = objectDBOpt.get();
}

In short, if you've tried all of the other answers, just make sure you look back to check you're loading from the database first if you haven't provided all the @JsonIgnore properties and are using them in your database query.

I think you are asking two things which are not necessarily the same

I want to extract every 6th element of the original

You can do this by indexing a sequence:

foo <- 1:120
foo[1:20*6]

I would like to create a vector in which each element is the i+6th element of another vector.

An easy way to do this is to supplement a logical factor with FALSEs until i+6:

foo <- 1:120
i <- 1
foo[1:(i+6)==(i+6)]
[1]   7  14  21  28  35  42  49  56  63  70  77  84  91  98 105 112 119

i <- 10
foo[1:(i+6)==(i+6)]
[1]  16  32  48  64  80  96 112

I have used a trick to counter this issue. Define a global variable var audio;

and in the function check

if(audio === undefined)
{
   audio = new Audio(url);
}

and in the stop function

audio.pause();
audio = undefined;

so the next call of audio.play, audio will be ready from '0' currentTime

I used

audio.pause();
audio.currentTime =0.0; 

but it didn't work. Thanks.

At first you need to understand first, that Tomcat is a Java application. So, to see which java version Tomcat is using, you can just simply find the script file from which Tomcat is started, usually catalina.sh.

Inside this file, you will get something like below:

catalina.sh:#   JAVA_HOME       Must point at your Java Development Kit installation.
catalina.sh:#                   Defaults to JAVA_HOME if empty.
catalina.sh:  [ -n "$JAVA_HOME" ] && JAVA_HOME=`cygpath --unix "$JAVA_HOME"`
catalina.sh:  JAVA_HOME=`cygpath --absolute --windows "$JAVA_HOME"`
catalina.sh:    echo "Using JAVA_HOME:       $JAVA_HOME"

By default, JAVA_HOME should be empty, which mean it will use the default version of java, or you can test with: echo $JAVA_HOME

And then use "java -version" to see which version you default java is.

And vice versa by setting this property: JAVA_HOME, you can configure which Java version to use when starting Tomcat.

I ran into this issue, in which I had a small number of fields I wanted to exclude only from serialization, so I developed a fairly simple solution that uses Gson's @Expose annotation with custom exclusion strategies.

The only built-in way to use @Expose is by setting GsonBuilder.excludeFieldsWithoutExposeAnnotation(), but as the name indicates, fields without an explicit @Expose are ignored. As I only had a few fields I wanted to exclude, I found the prospect of adding the annotation to every field very cumbersome.

I effectively wanted the inverse, in which everything was included unless I explicitly used @Expose to exclude it. I used the following exclusion strategies to accomplish this:

new GsonBuilder()
        .addSerializationExclusionStrategy(new ExclusionStrategy() {
            @Override
            public boolean shouldSkipField(FieldAttributes fieldAttributes) {
                final Expose expose = fieldAttributes.getAnnotation(Expose.class);
                return expose != null && !expose.serialize();
            }

            @Override
            public boolean shouldSkipClass(Class<?> aClass) {
                return false;
            }
        })
        .addDeserializationExclusionStrategy(new ExclusionStrategy() {
            @Override
            public boolean shouldSkipField(FieldAttributes fieldAttributes) {
                final Expose expose = fieldAttributes.getAnnotation(Expose.class);
                return expose != null && !expose.deserialize();
            }

            @Override
            public boolean shouldSkipClass(Class<?> aClass) {
                return false;
            }
        })
        .create();

Now I can easily exclude a few fields with @Expose(serialize = false) or @Expose(deserialize = false) annotations (note that the default value for both @Expose attributes is true). You can of course use @Expose(serialize = false, deserialize = false), but that is more concisely accomplished by declaring the field transient instead (which does still take effect with these custom exclusion strategies).

Since you only wish for the root activity to be reshown when the app is launched, maybe you can get this behavior by changing launch modes, etc. in the manifest?

For instance, have you tried applying the android:clearTaskOnLaunch="true" attribute to your launch activity, perhaps in tandem with android:launchMode="singleInstance"?

Tasks and Back Stack is a great resource for fine-tuning this sort of behavior.

In your example problem is passed table name pattern in getTables function of DatabaseMetaData.

Some database supports Uppercase identifier, some support lower case identifiers. For example oracle fetches the table name in upper case, while postgreSQL fetch it in lower case.

DatabaseMetaDeta provides a method to determine how the database stores identifiers, can be mixed case, uppercase, lowercase see:http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#storesMixedCaseIdentifiers()

From below example, you can get all tables and view of providing table name pattern, if you want only tables then remove "VIEW" from TYPES array.

public class DBUtility {

If you do not need the Visual Studio Hosting Process:

Uncheck the option: Project->Properties->Debug->Enable the Visual Studio Hosting Process

And then build.

If you still face the problem:

Go to Project->Properties->Build Events->Post-Build Event Command line and paste the following:

call "$(DevEnvDir)..\..\vc\vcvarsall.bat" x86
"$(DevEnvDir)..\..\vc\bin\EditBin.exe" "$(TargetPath)"  /LARGEADDRESSAWARE

Now, build the project.

Such renaming is quite easy, for example with os and glob modules:

import glob, os

def rename(dir, pattern, titlePattern):
    for pathAndFilename in glob.iglob(os.path.join(dir, pattern)):
        title, ext = os.path.splitext(os.path.basename(pathAndFilename))
        os.rename(pathAndFilename, 
                  os.path.join(dir, titlePattern % title + ext))

You could then use it in your example like this:

rename(r'c:\temp\xx', r'*.doc', r'new(%s)')

The above example will convert all *.doc files in c:\temp\xx dir to new(%s).doc, where %s is the previous base name of the file (without extension).

I will add my answer since I don't use any of the other answers provided.

With the Support Library v7, all the styles are actually already defined and ready to use, for the standard buttons, all of these styles are available:

style="@style/Widget.AppCompat.Button"
style="@style/Widget.AppCompat.Button.Colored"
style="@style/Widget.AppCompat.Button.Borderless"
style="@style/Widget.AppCompat.Button.Borderless.Colored"

Widget.AppCompat.Button:

Widget.AppCompat.Button.Colored:

Widget.AppCompat.Button.Borderless

Widget.AppCompat.Button.Borderless.Colored:

To answer the question, the style to use is therefore

<Button style="@style/Widget.AppCompat.Button.Colored"
.......
.......
.......
android:text="Button"/>

How to change the color

For the whole app:

The color of all the UI controls (not only buttons, but also floating action buttons, checkboxes etc.) is managed by the attribute colorAccent as explained here. You can modify this style and apply your own color in your theme definition:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    ...
    <item name="colorAccent">@color/Orange</item>
</style>

For a specific button:

If you need to change the style of a specific button, you can define a new style, inheriting one of the parent styles described above. In the example below I just changed the background and font colors:

<style name="AppTheme.Button" parent="Widget.AppCompat.Button.Colored">
    <item name="colorButtonNormal">@color/Red</item>
    <item name="android:textColor">@color/White</item>
</style>

Then you just need to apply this new style on the button with:

android:theme="@style/AppTheme.Button"

To set a default button design in a layout, add this line to the styles.xml theme:

<item name="buttonStyle">@style/btn</item>

where @style/btn is your button theme. This sets the button style for all the buttons in a layout with a specific theme

Raymond Chen has a really excellent blog post on this:

GUIDs are globally unique, but substrings of GUIDs aren't

Checkout react icons pretty dope and worked well.

header( "Location: http://www.domain.com/user.php" );

But you can't first do an echo, and then redirect.

An addition informative point that goes well with the answer by StompChicken above.

The fundamental difference between discriminative models and generative models is:

Discriminative models learn the (hard or soft) boundary between classes

Generative models model the distribution of individual classes

Edit:

A Generative model is the one that can generate data. It models both the features and the class (i.e. the complete data).

If we model P(x,y): I can use this probability distribution to generate data points - and hence all algorithms modeling P(x,y) are generative.

Eg. of generative models

• Naive Bayes models P(c) and P(d|c) - where c is the class and d is the feature vector.

  Also, P(c,d) = P(c) * P(d|c)

  Hence, Naive Bayes in some form models, P(c,d)

• Bayes Net

• Markov Nets

A discriminative model is the one that can only be used to discriminate/classify the data points. You only require to model P(y|x) in such cases, (i.e. probability of class given the feature vector).

Eg. of discriminative models:

• logistic regression

• Neural Networks

• Conditional random fields

In general, generative models need to model much more than the discriminative models and hence are sometimes not as effective. As a matter of fact, most (not sure if all) unsupervised learning algorithms like clustering etc can be called generative, since they model P(d) (and there are no classes:P)

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide(), with additional arguments, as follows:

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this).hide('slide',{direction:'right'},1000);

            });
    });

JS Fiddle demo.

Without using jQuery UI, you could achieve your aim just using animate():

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this)
                    .animate(
                        {
                            'margin-left':'1000px'
                            // to move it towards the right and, probably, off-screen.
                        },1000,
                        function(){
                            $(this).slideUp('fast');
                            // once it's finished moving to the right, just 
                            // removes the the element from the display, you could use
                            // `remove()` instead, or whatever.
                        }
                        );

            });
    });

If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js

Instead of an arraylist or dictionary you can also use a dynamic. Most of the time I use EasyHttp for this, but sure there will by other projects that do the same. An example below:

var http = new HttpClient();
http.Request.Accept = HttpContentTypes.ApplicationJson;
var response = http.Get("url");
var body = response.DynamicBody;
Console.WriteLine("Name {0}", body.AppName.Description);
Console.WriteLine("Name {0}", body.AppName.Value);

On NuGet: EasyHttp

According to the latest documentation about PyMongo titled Insert a Document (insert is deprecated) and following defensive approach, you should insert and update as follows:

result = mycollection.insert_one(post)
post = mycollection.find_one({'_id': result.inserted_id})

if post is not None:
    post['newfield'] = "abc"
    mycollection.save(post)

I wrote this in HLSL for our rendering engine, it has no conditions in it:

    float3  HSV2RGB( float3 _HSV )
    {
        _HSV.x = fmod( 100.0 + _HSV.x, 1.0 );                                       // Ensure [0,1[

        float   HueSlice = 6.0 * _HSV.x;                                            // In [0,6[
        float   HueSliceInteger = floor( HueSlice );
        float   HueSliceInterpolant = HueSlice - HueSliceInteger;                   // In [0,1[ for each hue slice

        float3  TempRGB = float3(   _HSV.z * (1.0 - _HSV.y),
                                    _HSV.z * (1.0 - _HSV.y * HueSliceInterpolant),
                                    _HSV.z * (1.0 - _HSV.y * (1.0 - HueSliceInterpolant)) );

        // The idea here to avoid conditions is to notice that the conversion code can be rewritten:
        //    if      ( var_i == 0 ) { R = V         ; G = TempRGB.z ; B = TempRGB.x }
        //    else if ( var_i == 2 ) { R = TempRGB.x ; G = V         ; B = TempRGB.z }
        //    else if ( var_i == 4 ) { R = TempRGB.z ; G = TempRGB.x ; B = V     }
        // 
        //    else if ( var_i == 1 ) { R = TempRGB.y ; G = V         ; B = TempRGB.x }
        //    else if ( var_i == 3 ) { R = TempRGB.x ; G = TempRGB.y ; B = V     }
        //    else if ( var_i == 5 ) { R = V         ; G = TempRGB.x ; B = TempRGB.y }
        //
        // This shows several things:
        //  . A separation between even and odd slices
        //  . If slices (0,2,4) and (1,3,5) can be rewritten as basically being slices (0,1,2) then
        //      the operation simply amounts to performing a "rotate right" on the RGB components
        //  . The base value to rotate is either (V, B, R) for even slices or (G, V, R) for odd slices
        //
        float   IsOddSlice = fmod( HueSliceInteger, 2.0 );                          // 0 if even (slices 0, 2, 4), 1 if odd (slices 1, 3, 5)
        float   ThreeSliceSelector = 0.5 * (HueSliceInteger - IsOddSlice);          // (0, 1, 2) corresponding to slices (0, 2, 4) and (1, 3, 5)

        float3  ScrollingRGBForEvenSlices = float3( _HSV.z, TempRGB.zx );           // (V, Temp Blue, Temp Red) for even slices (0, 2, 4)
        float3  ScrollingRGBForOddSlices = float3( TempRGB.y, _HSV.z, TempRGB.x );  // (Temp Green, V, Temp Red) for odd slices (1, 3, 5)
        float3  ScrollingRGB = lerp( ScrollingRGBForEvenSlices, ScrollingRGBForOddSlices, IsOddSlice );

        float   IsNotFirstSlice = saturate( ThreeSliceSelector );                   // 1 if NOT the first slice (true for slices 1 and 2)
        float   IsNotSecondSlice = saturate( ThreeSliceSelector-1.0 );              // 1 if NOT the first or second slice (true only for slice 2)

        return  lerp( ScrollingRGB.xyz, lerp( ScrollingRGB.zxy, ScrollingRGB.yzx, IsNotSecondSlice ), IsNotFirstSlice );    // Make the RGB rotate right depending on final slice index
    }

I can't repro, but I suspect that in your actual code there is a constraint somewhere that T : class - you need to propagate that to make the compiler happy, for example (hard to say for sure without a repro example):

public class Derived<SomeModel> : Base<SomeModel> where SomeModel : class, IModel
                                                                    ^^^^^
                                                                 see this bit

I don't know if this would work because I'm pretty sure that the keys aren't stored in the order they are added, but you could cast the KeysCollection to a List and then get the last key in the list... but it would be worth having a look.

The only other thing I can think of is to store the keys in a lookup list and add the keys to the list before you add them to the dictionary... it's not pretty tho.

You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

Most of the time, the best solution is using distinct() from dplyr, as has already been suggested.

However, here's another approach that uses the slice() function from dplyr.

# Generate fake data for the example
  library(dplyr)
  set.seed(123)
  df <- data.frame(
    x = sample(0:1, 10, replace = T),
    y = sample(0:1, 10, replace = T),
    z = 1:10
  )

# In each group of rows formed by combinations of x and y
# retain only the first row

    df %>%
      group_by(x, y) %>%
      slice(1)

Difference from using the distinct() function

The advantage of this solution is that it makes it explicit which rows are retained from the original dataframe, and it can pair nicely with the arrange() function.

Let's say you had customer sales data and you wanted to retain one record per customer, and you want that record to be the one from their latest purchase. Then you could write:

customer_purchase_data %>%
   arrange(desc(Purchase_Date)) %>%
   group_by(Customer_ID) %>%
   slice(1)

Mongo shell command that worked for me:

db.getCollection(<collection_name>).aggregate([{"$match": {'<key>': '<value to match>'}}, {"$group": {'_id': {'<group_by_attribute>': "$group_by_attribute"}}}])

If your project is a single page application, (eg project created by vue init webpack myproject), I found this way is most intuitive and simple:

In main.js

import moment from 'moment'

Vue.prototype.moment = moment

Then in your template, simply use

<span>{{moment(date).format('YYYY-MM-DD')}}</span>

To write:

using (System.IO.StreamWriter file =
new System.IO.StreamWriter(System.IO.File.Create(filePath).Dispose()))
{
    file.WriteLine("your text here");
}

Have you tried the built in method to convert a stream to a string? It's part of the Apache Commons library (org.apache.commons.io.IOUtils).

Then your code would be this one line:

String total = IOUtils.toString(inputStream);

The documentation for it can be found here: http://commons.apache.org/io/api-1.4/org/apache/commons/io/IOUtils.html#toString%28java.io.InputStream%29

The Apache Commons IO library can be downloaded from here: http://commons.apache.org/io/download_io.cgi

You could use following method to do that:

Using Windows Powershell, it possible to get the data you need in the following way

Caption:

(Get-WmiObject -class Win32_OperatingSystem).Caption

ReleaseId:

(Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name ReleaseId).ReleaseId

version:

(Get-CimInstance Win32_OperatingSystem).version

For Python 3, try the following:

import sys
!conda install --yes --prefix {sys.prefix} scikit-image

var html = '';
var red;
var green;
var blue;
var rgbColor;

for ( var i = 1; i <= 100; i += 1) {
  red = Math.floor(Math.random() * 256 );
  green = Math.floor(Math.random() * 256 );
  blue = Math.floor(Math.random() * 256 );
  rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';
  html += '<div style="background-color:' + rgbColor + '"></div>';  
}

document.write(html);

I know it is super old, but in my case I fixed it quite quick.

I was getting this same error while being one commit ahead of master. Then I found the current Stack Overflow post. However before proceeding with the suggested ideas, I just decided to make a new commit and try again with the push to origin and it worked smoothly.

I don't know why, but maybe it is useful for somebody else.

I believe you can use multiprocessing and not depend on a 3rd party package:

import multiprocessing
import requests

def call_with_timeout(func, args, kwargs, timeout):
    manager = multiprocessing.Manager()
    return_dict = manager.dict()

    # define a wrapper of `return_dict` to store the result.
    def function(return_dict):
        return_dict['value'] = func(*args, **kwargs)

    p = multiprocessing.Process(target=function, args=(return_dict,))
    p.start()

    # Force a max. `timeout` or wait for the process to finish
    p.join(timeout)

    # If thread is still active, it didn't finish: raise TimeoutError
    if p.is_alive():
        p.terminate()
        p.join()
        raise TimeoutError
    else:
        return return_dict['value']

call_with_timeout(requests.get, args=(url,), kwargs={'timeout': 10}, timeout=60)

The timeout passed to kwargs is the timeout to get any response from the server, the argument timeout is the timeout to get the complete response.

I needed to detect IE vs most everything else and I didn't want to depend on the UA string. I found that using es6number with Modernizr did exactly what I wanted. I don't have much concern with this changing as I don't expect IE to ever support ES6 Number. So now I know the difference between any version of IE vs Edge/Chrome/Firefox/Opera/Safari.

More details here: http://caniuse.com/#feat=es6-number

Note that I'm not really concerned about Opera Mini false negatives. You might be.

Specifying a default value would also work, assuming a default value is appropriate.

The content is not ready yet, you can move your js to the end of the file or do

<script>
$(function () { 
    $( '.expand' ).click(function() {
       $( '.img_display_content' ).show();
    });
});

So that the document waits to be loaded before running.

I was facing the same problem. To handle it I set a OntouchListener to the dialog and do nothing inside. But Dialog dismiss when rotating screen too. To fix it I set a variable to tell me if the dialog has normally dismissed. Then I set a OnDismissListener to my dialog and inside I check the variable. If the dialog has dismmiss normally I do nothin, or else I run the dialog again (and setting his state as when dismissing in my case).

Please try this

    <input type="button" value="Home" class="homebutton" id="btnHome" onClick="Javascript:window.location.href = 'http://www.website.com/index.php';" />

window.location.href example:

 window.location.href = 'http://www.google.com'; //Will take you to Google.

window.open() example:

     window.open('http://www.google.com'); //This will open Google in a new window.

I had a fully working project to which I was doing a minor change when this occured after updateting the SDK. Eclipse updated the SDK and the ADT but I could still not build the project. Exlipse said there were no further updates available.

The problem persisted until I manually uninstalled the ADT from eclipse and re-installed it. Only then would my project build. I had restarted eclipse inbetween each step.

I just learned of another option for solving this problem. If you load the jquery-turbolinks gem it will bind the Rails Turbolinks events to the document.ready events so you can write your jQuery in the usual way. You just add jquery.turbolinks right after jquery in the js manifest file (by default: application.js).

Another option is Sheet1.Rows(x & ":" & Sheet1.Rows.Count).ClearContents (or .Clear). The reason you might want to use this method instead of .Delete is because any cells with dependencies in the deleted range (e.g. formulas that refer to those cells, even if empty) will end up showing #REF. This method will preserve formula references to the cleared cells.

1. origin - This is a custom and most common name to point to remote.

$ git remote add origin https://github.com/git/git.git --- You will run this command to link your github project to origin. Here origin is user-defined. You can rename it by $ git remote rename old-name new-name

2. master - The default branch name in Git is master. For both remote and local computer.

3. origin/master - This is just a pointer to refer master branch in remote repo. Remember i said origin points to remote.

$ git fetch origin - Downloads objects and refs from remote repository to your local computer [origin/master]. That means it will not affect your local master branch unless you merge them using $ git merge origin/master. Remember to checkout the correct branch where you need to merge before run this command

Note: Fetched content is represented as a remote branch. Fetch gives you a chance to review changes before integrating them into your copy of the project. To show changes between yours and remote $git diff master..origin/master

<h2>Image Modal</h2>
<p>In this example, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>

<img id="myImg" src="img_snow.jpg" alt="Snow" style="width:100%;max-width:300px">

<!-- The Modal -->
<div id="myModal" class="modal">
  <span class="close">&times;</span>
  <img class="modal-content" id="img01">
  <div id="caption"></div>
</div>

<script>
// Get the modal
var modal = document.getElementById("myModal");

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById("myImg");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
  modal.style.display = "block";
  modalImg.src = this.src;
  captionText.innerHTML = this.alt;

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("modal")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() { 
  modal.style.display = "none";
}

Adding to what @Hitesh-sahu said you need all the VC++ redistribution packages for it to turn green. I referred to this thread from wampserver forum. You can install this little tool (check_vcredist) from the tools section here which will check if all the needed dependencies are installed (see attached image) and it will also provide links to missing ones. If you are using x64 version of Windows like I do and your wampserver does not turn green even after installing all the packages then uninstall and do a fresh installation again. Hope it helps.

An example of how to do this using a lambda expression would be:

issublist = lambda x, y: 0 in [_ in x for _ in y]

I had a single page application on entering URL it was creating a HashMap (used by my webpage) which contained data from multiple databases. I did following things to load everything during server start time-

1- Created ContextListenerClass

public class MyAppContextListener implements ServletContextListener
    @Autowired

    private  MyDataProviderBean myDataProviderBean; 

    public MyDataProviderBean getMyDataProviderBean() {

        return MyDataProviderBean;

    }

    public void setMyDataProviderBean(MyDataProviderBean MyDataProviderBean) {

        this.myDataProviderBean = MyDataProviderBean;

    }

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {

        System.out.println("ServletContextListener destroyed");

    }


    @Override

    public void contextInitialized(ServletContextEvent context) {

        System.out.println("ServletContextListener started");

        ServletContext sc = context.getServletContext();

        WebApplicationContext springContext = WebApplicationContextUtils.getWebApplicationContext(sc);

        MyDataProviderBean MyDataProviderBean = (MyDataProviderBean)springContext.getBean("myDataProviderBean");

        Map<String, Object> myDataMap = MyDataProviderBean.getDataMap();

        sc.setAttribute("myMap", myDataMap);

    }

2- Added below entry in web.xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> 
<listener>
    <listener-class>com.context.listener.MyAppContextListener</listener-class>
</listener>

3- In my Controller Class updated code to first check for Map in servletContext

    @RequestMapping(value = "/index", method = RequestMethod.GET)
        public String index(@ModelAttribute("model") ModelMap model) {

            Map<String, Object> myDataMap = new HashMap<String, Object>();
            if (context != null && context.getAttribute("myMap")!=null)
            {

                myDataMap=(Map<String, Object>)context.getAttribute("myMap");
            }

            else
            {

                myDataMap = myDataProviderBean.getDataMap();
            }

            for (String key : myDataMap.keySet())
            {
                model.addAttribute(key, myDataMap.get(key));
            }
            return "myWebPage";

        }

With this much change when I start my tomcat it loads dataMap during startTime and puts everything in servletContext which is then used by Controller Class to get results from already populated servletContext .

If using @worldofjr answer in jQuery you are getting error:

e.relatedTarget.data is not a function

you should use:

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = $(e.relatedTarget).data('load-url');
    $(this).find('.modal-body').load(loadurl);
});

Not that e.relatedTarget if wrapped by $(..)

I was getting the error in latest Bootstrap 3 and after using this method it's working without any problem.

Another approach could be to assume that your base image gets behind quite quickly (and that's very likely to happen), and force another image build of your application periodically (e.g. every week) and then re-deploy it if it has changed.

As far as I can tell, popular base images like the official Debian or Java update their tags to cater for security fixes, so tags are not immutable (if you want a stronger guarantee of that you need to use the reference [image:@digest], available in more recent Docker versions). Therefore, if you were to build your image with docker build --pull, then your application should get the latest and greatest of the base image tag you're referencing.

Since mutable tags can be confusing, it's best to increment the version number of your application every time you do this so that at least on your side things are cleaner.

So I'm not sure that the script suggested in one of the previous answers does the job, since it doesn't rebuild you application's image - it just updates the base image tag and then it restarts the container, but the new container still references the old base image hash.

I wouldn't advocate for running cron-type jobs in containers (or any other processes, unless really necessary) as this goes against the mantra of running only one process per container (there are various arguments about why this is better, so I'm not going to go into it here).

Depending on your regex variant, you might be able to do simply this:

([\w-]+)

Also, you probably don't need the parentheses unless this is part of a larger expression.

explain: 1.the first one declare the variable in array.

2.the second array_push method is used to push the string in the array variable.

3.finally it will print the result.

4.the second method is directly store the string in the array.

5.the data is printed in the array values in using print_r method.

this two are same

If you have an instance function (i.e. one that gets passed self) you can use self to get a reference to the class using self.__class__

For example in the code below tornado creates an instance to handle get requests, but we can get hold of the get_handler class and use it to hold a riak client so we do not need to create one for every request.

import tornado.web
import riak

class get_handler(tornado.web.requestHandler):
    riak_client = None

    def post(self):
        cls = self.__class__
        if cls.riak_client is None:
            cls.riak_client = riak.RiakClient(pb_port=8087, protocol='pbc')
        # Additional code to send response to the request ...
    

you can parse string with int.parse('your string value');.

Example:- int num = int.parse('110011'); print(num); // prints 110011 ;

The direct answer is that you can't. You must select either an aggregate or something that you are grouping by.

So, you need an alternative approach.

1). Take you current query and join the base data back on it

SELECT
  cpe.*
FROM
  Filteredfmgcms_claimpaymentestimate cpe
INNER JOIN
  (yourQuery) AS lookup
    ON  lookup.MaxData           = cpe.createdOn
    AND lookup.fmgcms_cpeclaimid = cpe.fmgcms_cpeclaimid

2). Use a CTE to do it all in one go...

WITH
  sequenced_data AS
(
  SELECT
    *,
    ROW_NUMBER() OVER (PARITION BY fmgcms_cpeclaimid ORDER BY CreatedOn DESC) AS sequence_id
  FROM
    Filteredfmgcms_claimpaymentestimate
  WHERE
    createdon < 'reportstartdate'
)
SELECT
  *
FROM
  sequenced_data
WHERE
  sequence_id = 1

NOTE: Using ROW_NUMBER() will ensure just one record per fmgcms_cpeclaimid. Even if multiple records are tied with the exact same createdon value. If you can have ties, and want all records with the same createdon value, use RANK() instead.

The clean, install and deploy phases are valid lifecycle phases and invoking them will trigger all the phases preceding them, and the goals bound to these phases.

mvn clean install

This command invokes the clean phase and then the install phase sequentially:

• clean: removes files generated at build-time in a project's directory (target by default)
• install: installs the package into the local repository, for use as a dependency in other projects locally.

mvn deploy

This command invokes the deploy phase:

• deploy: copies the final package to the remote repository for sharing with other developers and projects.

mvn release

This is not a valid phase nor a goal so this won't do anything. But if refers to the Maven Release Plugin that is used to automate release management. Releasing a project is done in two steps: prepare and perform. As documented:

Preparing a release goes through the following release phases:

• Check that there are no uncommitted changes in the sources
• Check that there are no SNAPSHOT dependencies
• Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
• Transform the SCM information in the POM to include the final destination of the tag
• Run the project tests against the modified POMs to confirm everything is in working order
• Commit the modified POMs
• Tag the code in the SCM with a version name (this will be prompted for)
• Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
• Commit the modified POMs

And then:

Performing a release runs the following release phases:

• Checkout from an SCM URL with optional tag
• Run the predefined Maven goals to release the project (by default, deploy site-deploy)

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

System32 is where Windows historically placed all 32bit DLLs, and System was for the 16bit DLLs. When microsoft created the 64 bit OS, everyone I know of expected the files to reside under System64, but Microsoft decided it made more sense to put 64bit files under System32. The only reasoning I have been able to find, is that they wanted everything that was 32bit to work in a 64bit Windows w/o having to change anything in the programs -- just recompile, and it's done. The way they solved this, so that 32bit applications could still run, was to create a 32bit windows subsystem called Windows32 On Windows64. As such, the acronym SysWOW64 was created for the System directory of the 32bit subsystem. The Sys is short for System, and WOW64 is short for Windows32OnWindows64.
Since windows 16 is already segregated from Windows 32, there was no need for a Windows 16 On Windows 64 equivalence. Within the 32bit subsystem, when a program goes to use files from the system32 directory, they actually get the files from the SysWOW64 directory. But the process is flawed.

It's a horrible design. And in my experience, I had to do a lot more changes for writing 64bit applications, that simply changing the System32 directory to read System64 would have been a very small change, and one that pre-compiler directives are intended to handle.

Given some table, you can find which rows are not locked with SELECT FOR UPDATESKIP LOCKED.

For example, this query will lock (and return) every unlocked row:

SELECT * FROM mytable FOR UPDATE SKIP LOCKED

You can use sprintf in combination with std::string.c_str().

c_str() returns a const char* and works with sprintf:

string a = "test";
string b = "text.txt";
string c = "text1.txt";
char* x = new char[a.length() + b.length() + c.length() + 32];

sprintf(x, "%s %s > %s", a.c_str(), b.c_str(), c.c_str() );

string str = x;
delete[] x;

or you can use a pre-allocated char array if you know the size:

string a = "test";
string b = "text.txt";
string c = "text1.txt";
char x[256];

sprintf(x, "%s %s > %s", a.c_str(), b.c_str(), c.c_str() );

How I would do this

git checkout master
git pull origin master
git merge test
git push origin master

If I have a local branch from a remote one, I don't feel comfortable with merging other branches than this one with the remote. Also I would not push my changes, until I'm happy with what I want to push and also I wouldn't push things at all, that are only for me and my local repository. In your description it seems, that test is only for you? So no reason to publish it.

git always tries to respect yours and others changes, and so will --rebase. I don't think I can explain it appropriately, so have a look at the Git book - Rebasing or git-ready: Intro into rebasing for a little description. It's a quite cool feature

For your question as asked

Columns(3).Insert
Range("c1:c4") = Application.Transpose(Array("Loc", "uk", "us", "nj"))

If you had a way of automatically looking up the data (ie matching uk against employer id) then you could do that in VBA

Assume you have one table with name 'table1'. It contain one column 'col1' with varchar type. Query to crate table is give below

CREATE TABLE `table1` (
    `col1` VARCHAR(50) NULL DEFAULT NULL
)

Now if you want to insert number from 1 to 50 in that table then use following stored procedure

DELIMITER $$  
CREATE PROCEDURE ABC()

   BEGIN
      DECLARE a INT Default 1 ;
      simple_loop: LOOP         
         insert into table1 values(a);
         SET a=a+1;
         IF a=51 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

To call that stored procedure use

CALL `ABC`()

For the background color - the fill property can be accessed like so:

svgElement.style.fill = '#fff';

To set the border color, do the same for the stroke property.

Please refer to the W3C reference on SVG, as it's a broad issue.

There is some ways to prevent it.

However the user will be always able to turn the javascript off or just look on the source code of the page.

Some examples (require jQuery)

/**
* Stop every keystroke with ctrl key pressed
*/
$(".textbox").keydown(function(){
    if (event.ctrlKey==true) {
        return false;
    }
});

/**
* Clear all data of clipboard on focus
*/
$(".textbox").focus(function(){
    if ( window.clipboardData ) {
        window.clipboardData.setData('text','');
    }
});

/**
* Block the paste event
*/
$(".textbox").bind('paste',function(e){return false;});

Edit: How Tim Down said, this functions are all browser dependents.

To get the eth0 interface MAC address,

import psutil

nics = psutil.net_if_addrs()['eth0']

for interface in nics:
   if interface.family == 17:
      print(interface.address)

After you commit your object into the db the object receives a value in its ID field.

So:

myObject.Field1 = "value";

// Db is the datacontext
db.MyObjects.InsertOnSubmit(myObject);
db.SubmitChanges();

// You can retrieve the id from the object
int id = myObject.ID;

looks like you have maven project and so resources are in classpath by

go for

getClass().getResource("classpath:storedProcedures.sql")

Regex can be used for this with some detailed info for validation, for example this code can be used to validate any date in (DD/MM/yyyy) format with proper date and month value and year between (1950-2050)

    public Boolean checkDateformat(String dateToCheck){   
        String rex="([0]{1}[1-9]{1}|[1-2]{1}[0-9]{1}|[3]{1}[0-1]{1})+
        \/([0]{1}[1-9]{1}|[1]{1}[0-2]{2})+
        \/([1]{1}[9]{1}[5-9]{1}[0-9]{1}|[2]{1}[0]{1}([0-4]{1}+
        [0-9]{1}|[5]{1}[0]{1}))";

        return(dateToCheck.matches(rex));
    }

You are getting arithmetic overflow. this means you are trying to make a conversion impossible to be made. This error is thrown when you try to make a conversion and the destiny data type is not enough to convert the origin data. For example:

If you try to convert 100.52 to decimal(4,2) you will get this error. The number 100.52 requires 5 positions and 2 of them are decimal.

Try to change the decimal precision to something like 16,2 or higher. Try with few records first then use it to all your select.

If, like me, you have a problem installing graphviz, you can visualize the tree by

1. exporting it with export_graphviz as shown in previous answers
2. Open the .dot file in a text editor
3. Copy the piece of code and paste it @ webgraphviz.com

extension UIImage {
    func fixImageOrientation() -> UIImage {
        UIGraphicsBeginImageContext(self.size)
        self.draw(at: .zero)
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return newImage ?? self
    }
}

1. Create extension like top example.

2. Call it: imageView.image?.fixImageOrientation() or UIImage(named: "someImage").fixImageOrientation()

3. Good luck all!

In my experience calling this worked great!

handler.removeCallbacksAndMessages(null);

In the docs for removeCallbacksAndMessages it says...

Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.

You need to write a selector which selects the correct <input> first. Ideally you use the element's ID $('#element_id'), failing that the ID of it's container $('#container_id input'), or the element's class $('input.class_name').

Your element has none of these and no context, so it's hard to tell you how to select it.

Once you have figured out the proper selector, you'd use the attr method to access the element's attributes. To get the name, you'd use $(selector).attr('name') which would return (in your example) 'xxxxx'.

I know that what I do is quite the workaround, however it works perfectly and that is the way I do it everytime.

Then, proceed like this:

• First make sure Chrome Developer Tools is undocked.
• Then, just move any side of the Dev Tools window to the middle of the element you want to inspect while hovered.

• Finally, hover the element, right click and inspect element, move your mouse into the Dev Tools window and you will be able to play with your element:hover css.

Cheers!
