Here you can resolve this issue, you need to add flavorDimension with productFlavors's name and need to define dimension as well, see below example and for more information see here https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

flavorDimensions 'yourAppName' //here defined dimensions
productFlavors {
    production {
        dimension 'yourAppName' //you just need to add this line
        //here you no need to write applicationIdSuffix because by default it will point to your app package which is also available inside manifest.xml file.

    }

    staging {
        dimension 'yourAppName' //added here also
        applicationIdSuffix ".staging"//(.staging) will be added after your default package name.
        //or you can also use applicationId="your_package_name.staging" instead of applicationIdSuffix but remember if you are using applicationId then You have to mention full package name.
        //versionNameSuffix "-staging"

    }

    develop {
        dimension 'yourAppName' //add here too
        applicationIdSuffix ".develop"
        //versionNameSuffix "-develop"

    }

I had the same problem. I tried every thing from the huge list of answer but in the end my problem was: I'm working with openCV so I need to combine C++ code in my code. To do this you should change the files which use objective-c and C++ to .mm I didn't changed one file and this file has no connection to the C++ code but I had to change it.

EABI = Embedded Application Binary Interface. It is such specifications to which an executable must conform in order to execute in a specific execution environment. It also specifies various aspects of compilation and linkage required for interoperation between toolchains used for the ARM Architecture. In this context when we speak about armeabi we speak about ARM architecture and GNU/Linux OS. Android follows the little-endian ARM GNU/Linux ABI.

armeabi application will run on ARMv5 (e.g. ARM9) and ARMv6 (e.g. ARM11). You may use Floating Point hardware if you build your application using proper GCC options like -mfpu=vfpv3 -mfloat-abi=softfp which tells compiler to generate floating point instructions for VFP hardware and enables the soft-float calling conventions. armeabi doesn't support hard-float calling conventions (it means FP registers are not used to contain arguments for a function), but FP operations in HW are still supported.

armeabi-v7a application will run on Cortex A# devices like Cortex A8, A9, and A15. It supports multi-core processors and it supports -mfloat-abi=hard. So, if you build your application using -mfloat-abi=hard, many of your function calls will be faster.

the simplest way to convert a string that has a delimiter like a comma is just to use the split method

"1,2,3,4".split(',') # "1", "2", "3", "4"]

you can find more info on how to use the split method in the ruby docs

Divides str into substrings based on a delimiter, returning an array of these substrings.

If pattern is a String, then its contents are used as the delimiter when splitting str. If pattern is a single space, str is split on whitespace, with leading whitespace and runs of contiguous whitespace characters ignored.

If pattern is a Regexp, str is divided where the pattern matches. Whenever the pattern matches a zero-length string, str is split into individual characters. If pattern contains groups, the respective matches will be returned in the array as well.

If pattern is omitted, the value of $; is used. If $; is nil (which is the default), str is split on whitespace as if ` ‘ were specified.

If the limit parameter is omitted, trailing null fields are suppressed. If limit is a positive number, at most that number of fields will be returned (if limit is 1, the entire string is returned as the only entry in an array). If negative, there is no limit to the number of fields returned, and trailing null fields are not suppressed.

Try below :

DECLARE @myDateTime DATETIME
SET @myDateTime = '2013-02-02'

-- Convert to string now
SELECT LEFT(CONVERT(VARCHAR, @myDateTime, 120), 10)

This is what worked for me. Attach the OnClickListener to the onBindView. I don't really know if this will impact the performance, but it seems to work fine with little code.

public void onBindViewHolder(ViewHolder holder, final int position) {
    holder.view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(context, "Recycle Click" + position, Toast.LENGTH_SHORT).show();
            }
    });
}

You can easily crop a Mat using opencv funtions.

setMouseCallback("Original",mouse_call);

The mouse_callis given below:

 void mouse_call(int event,int x,int y,int,void*)
    {
        if(event==EVENT_LBUTTONDOWN)
        {
            leftDown=true;
            cor1.x=x;
            cor1.y=y;
           cout <<"Corner 1: "<<cor1<<endl;

        }
        if(event==EVENT_LBUTTONUP)
        {
            if(abs(x-cor1.x)>20&&abs(y-cor1.y)>20) //checking whether the region is too small
            {
                leftup=true;
                cor2.x=x;
                cor2.y=y;
                cout<<"Corner 2: "<<cor2<<endl;
            }
            else
            {
                cout<<"Select a region more than 20 pixels"<<endl;
            }
        }

        if(leftDown==true&&leftup==false) //when the left button is down
        {
            Point pt;
            pt.x=x;
            pt.y=y;
            Mat temp_img=img.clone();
            rectangle(temp_img,cor1,pt,Scalar(0,0,255)); //drawing a rectangle continuously
            imshow("Original",temp_img);

        }
        if(leftDown==true&&leftup==true) //when the selection is done
        {

            box.width=abs(cor1.x-cor2.x);
            box.height=abs(cor1.y-cor2.y);
            box.x=min(cor1.x,cor2.x);
            box.y=min(cor1.y,cor2.y);
            Mat crop(img,box);   //Selecting a ROI(region of interest) from the original pic
            namedWindow("Cropped Image");
            imshow("Cropped Image",crop); //showing the cropped image
            leftDown=false;
            leftup=false;

        }
    }

You really shouldn't be doing this, the correct use of timeout is the right tool for the OP's problem and any other occasion where you just want to run something after a period of time. Joseph Silber has demonstrated that well in his answer. However, if in some non-production case you really want to hang the main thread for a period of time, this will do it.

function wait(ms){
   var start = new Date().getTime();
   var end = start;
   while(end < start + ms) {
     end = new Date().getTime();
  }
}

With execution in the form:

console.log('before');
wait(7000);  //7 seconds in milliseconds
console.log('after');

I've arrived here because I was building a simple test case for sequencing a mix of asynchronous operations around long-running blocking operations (i.e. expensive DOM manipulation) and this is my simulated blocking operation. It suits that job fine, so I thought I post it for anyone else who arrives here with a similar use case. Even so, it's creating a Date() object in a while loop, which might very overwhelm the GC if it runs long enough. But I can't emphasize enough, this is only suitable for testing, for building any actual functionality you should refer to Joseph Silber's answer.

Try this

function readRows() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var rows = sheet.getDataRange();
  var numRows = rows.getNumRows();
  //var values = rows.getValues();

  var Names = sheet.getRange("A2:A7");
  var Name = [
    Names.getCell(1, 1).getValue(),
    Names.getCell(2, 1).getValue(),
    .....
    Names.getCell(5, 1).getValue()]

You can define arrays simply as follows, instead of allocating and then assigning.

var arr = [1,2,3,5]

Your initial error was because of the following line, and ones like it

var Name[0] = Name_cell.getValue(); 

Since Name is already defined and you are assigning the values to its elements, you should skip the var, so just

Name[0] = Name_cell.getValue();

Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.

You can use get_cfg_var('cfg_file_path') for that:

To check whether the system is using a configuration file, try retrieving the value of the cfg_file_path configuration setting. If this is available, a configuration file is being used.

var_dump( get_cfg_var('cfg_file_path') );

And you can simply set the location of the php.ini. You're using the command line version, so using the -c parameter you can specifiy the location, e.g.

php -c /home/me/php.ini -f /home/me/test.php

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

import pandas as pd

a = ['2015-01-01' , '2015-02-01']

df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})

print(df)
#         date
#0  2015-01-01
#1  2015-02-01
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

df = df[~df['date'].isin(a)]

print(df)
#         date
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

If it's not a literal, you have to use \\\\ so that you get \\ which means an escaped backslash.

That's because there are two representations. In the string representation of your regex, you have "\\\\", Which is what gets sent to the parser. The parser will see \\ which it interprets as a valid escaped-backslash (which matches a single backslash).

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

Use HTML template instead!

Since the accepted answer would represent overloading script method, I would like to suggest another which is, in my opinion, much cleaner and more secure due to XSS risks which come with overloading scripts.

I made a demo to show you how to use it in an action and how to inject one template into another, edit and then add to the document DOM.

example html

<template id="mytemplate">
  <style>
     .image{
        width: 100%;
        height: auto;
     }
  </style>
  <a href="#" class="list-group-item">
    <div class="image">
      <img src="" />
    </div>
    <p class="list-group-item-text"></p>
  </a>
</template>

example js

// select
var t = document.querySelector('#mytemplate');

// set
t.content.querySelector('img').src = 'demo.png';
t.content.querySelector('p').textContent= 'demo text';

// add to document DOM
var clone = document.importNode(t.content, true); // where true means deep copy
document.body.appendChild(clone);

HTML <template>

• +Its content is effectively inert until activated. Essentially, your markup is hidden DOM and does not render.

• +Any content within a template won't have side effects. Scripts don't run, images don't load, audio doesn't play ...until the template is used.

• +Content is considered not to be in the document. Using document.getElementById() or querySelector() in the main page won't return child nodes of a template.

• +Templates can be placed anywhere inside of <head>, <body>, or <frameset> and can contain any type of content which is allowed in those elements. Note that "anywhere" means that <template> can safely be used in places that the HTML parser disallows.

Fall back

Browser support should not be an issue but if you want to cover all possibilities you can make an easy check:

To feature detect <template>, create the DOM element and check that the .content property exists:

function supportsTemplate() {
  return 'content' in document.createElement('template');
}

if (supportsTemplate()) {
  // Good to go!
} else {
  // Use old templating techniques or libraries.
}

Some insights about Overloading script method

• +Nothing is rendered - the browser doesn't render this block because the <script> tag has display:none by default.
• +Inert - the browser doesn't parse the script content as JS because its type is set to something other than "text/javascript".
• -Security issues - encourages the use of .innerHTML. Run-time string parsing of user-supplied data can easily lead to XSS vulnerabilities.

ok just so you know there is a program out there that's called DroidDraw. It can help you draw objects and try them one on top of the other. I tried your solution but I had animation under the smaller image so that didn't work. But then I tried to place one image in a relative layout that's suppose to be under first and then on top of that I drew the other image that is suppose to overlay and everything worked great. So RelativeLayout, DroidDraw and you are good to go :) Simple, no any kind of jiggery pockery :) and here is a bit of code for ya:

The logo is going to be on top of shazam background image.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/widget30"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ImageView
android:id="@+id/widget39"
android:layout_width="219px"
android:layout_height="225px"
android:src="@drawable/shazam_bkgd"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
</ImageView>
<ImageView
android:id="@+id/widget37"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/shazam_logo"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
</ImageView>
</RelativeLayout>

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.

Set cn = CreateObject("ADODB.Connection")
With cn
 .Provider = "Microsoft.Jet.OLEDB.4.0"
  .ConnectionString = "Data Source=D:\test.xls " & _
  ";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
  For i = 0 To rs.Fields.Count - 1
    Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
    strNaam = rs.Fields(0).Value
  Next
  rs.MoveNext
Loop
rs.Close

There are other ways, depending on what you want to do, such as GetString (GetString Method Description).

In rare cases (e.g., after a heavy transaction is commited) a running CHECKPOINT system process holding a FILE lock on the database file prevents transition to MULTI_USER mode.

You can also do this by service name.

First, try to find the service name of the respective pod which corresponds to multiple pods of the same service. kubectl get svc.

Next, run the following command to display logs from each container.

kubectl logs -f service/<service-name>

Here is a table of the different events and the levels of browser support. You need to pick an event which is supported across at least all modern browsers.

As you will see from the table, the keypress and change event do not have uniform support whereas the keyup event does.

Also make sure you attach the event handler using a cross-browser-compatible method...

userInfos.GroupBy(userInfo => userInfo.metric)
        .OrderBy(group => group.Key)
        .Select(group => Tuple.Create(group.Key, group.Count()));

Varargs are useful for any method that needs to deal with an indeterminate number of objects. One good example is String.format. The format string can accept any number of parameters, so you need a mechanism to pass in any number of objects.

String.format("This is an integer: %d", myInt);
String.format("This is an integer: %d and a string: %s", myInt, myString);

Also, make sure that your device isn't on airplane mode and/or that data usage is enabled.

The compiler is telling you that there are problems starting at line 122 in the middle of that strange FBI-CIA warning message. That message is not valid C++ code and is NOT commented out so of course it will cause compiler errors. Try removing that entire message.

Also, I agree with In silico: you should always tell us what you tried and exactly what error messages you got.

If you want to use mongoimport, you'll want to export this way:

db.getCollection('tables')
  .find({_id: 'q3hrnnoKu2mnCL7kE'})
  .forEach(function(x){printjsononeline(x)});

Try with this:

public static boolean userNameValidation(String name){

return name.matches("(?i)(^[a-z])((?![? .,'-]$)[ .]?[a-z]){3,24}$");
}

The feature you're looking for is filter. It is capable of doing a range of image effects, including brightness:

#myimage {
    filter: brightness(50%);
}

You can find a helpful article about it here: http://www.html5rocks.com/en/tutorials/filters/understanding-css/

An another: http://davidwalsh.name/css-filters

And most importantly, the W3C specs: https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/index.html

Note this is something that's only very recently coming into CSS as a feature. It is available, but a large number of browsers out there won't support it yet, and those that do support it will require a vendor prefix (ie -webkit-filter:, -moz-filter, etc).

It is also possible to do filter effects like this using SVG. SVG support for these effects is well established and widely supported (the CSS filter specs have been taken from the existing SVG specs)

Also note that this is not to be confused with the proprietary filter style available in old versions of IE (although I can predict a problem with the namespace clash when the new style drops its vendor prefix).

If none of that works for you, you could still use the existing opacity feature, but not the way you're thinking: simply create a new element with a solid dark colour, place it on top of your image, and fade it out using opacity. The effect will be of the image behind being darkened.

Finally you can check the browser support of filter here.

This did not work for me. I moved a repo from (e.g.) c:\project1\ to c:\repo\project1\ and Git for windows does not show any changes.

git status shows an error because one of the submodules "is not a git repository" and shows the old path. e.g. (names changed to protect IP)

fatal: Not a git repository: C:/project1/.git/modules/subproject/subproject2 fatal: 'git status --porcelain' failed in submodule subproject

I had to manually edit the .git files in the submodules to point to the correct relative path to the submodule's repo (in the main repo's .git/modules directory)

For any complex application, I suggest to use an lxc container. lxc containers are 'something in the middle between a chroot on steroids and a full fledged virtual machine'.

For example, here's a way to build 32-bit wine using lxc on an Ubuntu Trusty system:

sudo apt-get install lxc lxc-templates
sudo lxc-create -t ubuntu -n my32bitbox -- --bindhome $LOGNAME -a i386 --release trusty
sudo lxc-start -n my32bitbox
# login as yourself
sudo sh -c "sed s/deb/deb-src/ /etc/apt/sources.list >> /etc/apt/sources.list"
sudo apt-get install devscripts
sudo apt-get build-dep wine1.7
apt-get source wine1.7
cd wine1.7-*
debuild -eDEB_BUILD_OPTIONS="parallel=8" -i -us -uc -b
shutdown -h now   # to exit the container

Here is the wiki page about how to build 32-bit wine on a 64-bit host using lxc.

Simply creating a filter will do the trick. (Answered for Angular 1.6)

.filter('trustHtml', [
        '$sce',
        function($sce) {
            return function(value) {
                return $sce.trustAs('html', value);
            }
        }
    ]);

And use this as follow in the html.

<h2 ng-bind-html="someScopeValue | trustHtml"></h2>

Try this:

btn.requestFocusFromTouch();

I solved that adding a Web facet.

There is also the C way of doing callbacks: function pointers

//Define a type for the callback signature,
//it is not necessary, but makes life easier

//Function pointer called CallbackType that takes a float
//and returns an int
typedef int (*CallbackType)(float);  


void DoWork(CallbackType callback)
{
  float variable = 0.0f;

  //Do calculations

  //Call the callback with the variable, and retrieve the
  //result
  int result = callback(variable);

  //Do something with the result
}

int SomeCallback(float variable)
{
  int result;

  //Interpret variable

  return result;
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWork(&SomeCallback);
}

Now if you want to pass in class methods as callbacks, the declarations to those function pointers have more complex declarations, example:

//Declaration:
typedef int (ClassName::*CallbackType)(float);

//This method performs work using an object instance
void DoWorkObject(CallbackType callback)
{
  //Class instance to invoke it through
  ClassName objectInstance;

  //Invocation
  int result = (objectInstance.*callback)(1.0f);
}

//This method performs work using an object pointer
void DoWorkPointer(CallbackType callback)
{
  //Class pointer to invoke it through
  ClassName * pointerInstance;

  //Invocation
  int result = (pointerInstance->*callback)(1.0f);
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWorkObject(&ClassName::Method);
  DoWorkPointer(&ClassName::Method);
}

Here's a clean solution:

function test(str){
    //Note: should be /(abc)|(def)/i if you want it case insensitive
    var pattern = /(abc)|(def)/;
    return !str.match(pattern);
}

The answer is to DISABLE "Enable auto-completion on each input". Tested and works perfectly.

(function($) {
  var triggers = [];
  $.fn.floatingFixed = function(options) {
    options = $.extend({}, $.floatingFixed.defaults, options);
    var r = $(this).each(function() {
      var $this = $(this), pos = $this.position();
      pos.position = $this.css("position");
      $this.data("floatingFixedOrig", pos);
      $this.data("floatingFixedOptions", options);
      triggers.push($this);
    });
    windowScroll();
    return r;
  };

  $.floatingFixed = $.fn.floatingFixed;
  $.floatingFixed.defaults = {
    padding: 0
  };

  var $window = $(window);
  var windowScroll = function() {
    if(triggers.length === 0) { return; }
    var scrollY = $window.scrollTop();
    for(var i = 0; i < triggers.length; i++) {
      var t = triggers[i], opt = t.data("floatingFixedOptions");
      if(!t.data("isFloating")) {
        var off = t.offset();
        t.data("floatingFixedTop", off.top);
        t.data("floatingFixedLeft", off.left);
      }
      var top = top = t.data("floatingFixedTop");
      if(top < scrollY + opt.padding && !t.data("isFloating")) {
        t.css({position: 'fixed', top: opt.padding, left: t.data("floatingFixedLeft"), width: t.width() }).data("isFloating", true);
      } else if(top >= scrollY + opt.padding && t.data("isFloating")) {
        var pos = t.data("floatingFixedOrig");
        t.css(pos).data("isFloating", false);
      }
    }
  };

  $window.scroll(windowScroll).resize(windowScroll);
})(jQuery);

and then make any div as floating fixed by calling

$('#id of the div').floatingFixed();

If you create an image tag and add it to the DOM, either its onload or onerror event should fire. If onerror fires, the image doesn't exist on the server.

I have an idea too. C++ does have zero-overhead principle. But exceptions do not follow this principle, so sometimes they are turned off with compiler switch.

Let's look to this example:

#include <new>
#include <cstdio>
#include <cstdlib>

int main() {
    struct A {
        A() {
            printf("A()\n");
        }
        ~A() {
            printf("~A()\n");
        }
        char data[1000000000000000000] = {}; // some very big number
    };

    try {
        A *result = new A();
        printf("new passed: %p\n", result);
        delete result;
    } catch (std::bad_alloc) {
        printf("new failed\n");
    }
}

We allocate a big struct here, and check if allocation is successful, and delete it.

But if we have exceptions turned off, we can't use try block, and unable to handle new[] failure.

So how we can do that? Here is how:

#include <new>
#include <cstdio>
#include <cstdlib>

int main() {
    struct A {
        A() {
            printf("A()\n");
        }
        ~A() {
            printf("~A()\n");
        }
        char data[1000000000000000000] = {}; // some very big number
    };

    void *buf = malloc(sizeof(A));
    if (buf != nullptr) {
        A *result = new(buf) A();
        printf("new passed: %p\n", result);
        result->~A();
        free(result);
    } else {
        printf("new failed\n");
    }
}

• Use simple malloc
• Check if it is failed in a C way
• If it successful, we use placement new
• Manually call the destructor (we can't just call delete)
• call free, due we called malloc

UPD @Useless wrote a comment which opened to my view the existence of new(nothrow), which should be used in this case, but not the method I wrote before. Please don't use the code I wrote before. Sorry.

Here are two approaches. You may want to add handling for when the array is empty.

public static void FindMax()
{
    // Advantages: 
    // * Functional approach
    // * Compact code
    // Cons: 
    // * We are indexing into the array twice at each step
    // * The Range and IEnumerable add a bit of overhead
    // * Many people will find this code harder to understand

    int[] array = { 1, 5, 2, 7 };

    int maxIndex = Enumerable.Range(0, array.Length).Aggregate((max, i) => array[max] > array[i] ? max : i);
    int maxInt = array[maxIndex];

    Console.WriteLine($"Maximum int {maxInt} is found at index {maxIndex}");
}

public static void FindMax2()
{
    // Advantages: 
    // * Near-optimal performance

    int[] array = { 1, 5, 2, 7 };
    int maxIndex = -1;
    int maxInt = Int32.MinValue;

    // Modern C# compilers optimize the case where we put array.Length in the condition
    for (int i = 0; i < array.Length; i++)
    {
        int value = array[i];
        if (value > maxInt)
        {
            maxInt = value;
            maxIndex = i;
        }
    }

    Console.WriteLine($"Maximum int {maxInt} is found at index {maxIndex}");
}

Let's say you have a Login action which provides the user with a login screen, then receives the user name and password back after the user submits the form:

public ActionResult Login() {
    return View();
}

public ActionResult Login(string userName, string password) {
    // do login stuff
    return View();
}

MVC isn't being given clear instructions on which action is which, even though we can tell by looking at it. If you add [HttpGet] to the first action and [HttpPost] to the section action, MVC clearly knows which action is which.

Why? See Request Methods. Long and short: When a user views a page, that's a GET request and when a user submits a form, that's usually a POST request. HttpGet and HttpPost just restrict the action to the applicable request type.

[HttpGet]
public ActionResult Login() {
    return View();
}

[HttpPost]
public ActionResult Login(string userName, string password) {
    // do login stuff
    return View();
}

You can also combine the request method attributes if your action serves requests from multiple verbs:

[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)].

Use option -t for sendmail.

in your case - echo -e $mail | /usr/sbin/sendmail -t and add yout Recepient list to message itself like To: [email protected] [email protected] right after the line From:.....

-t option means - Read message for recipients. To:, Cc:, and Bcc: lines will be scanned for recipient addresses. The Bcc: line will be deleted before transmission.

Here is a concise way using lambdas and JDK 8 Supplier to fit everything in the outer try:

try (Connection con = DriverManager.getConnection(JDBC_URL, prop);
    PreparedStatement stmt = ((Supplier<PreparedStatement>)() -> {
    try {
        PreparedStatement s = con.prepareStatement("SELECT userid, name, features FROM users WHERE userid = ?");
        s.setInt(1, userid);
        return s;
    } catch (SQLException e) { throw new RuntimeException(e); }
    }).get();
    ResultSet resultSet = stmt.executeQuery()) {
}

If you instead had a data.frame (df) that had multiple columns and you want to vectorize you can do

as.matrix(df, ncol=1)

Mainly Nexus 7 modal issue , modal was going down the screen

  .modal:before {
    content: '';
    display: inline-block;
    height: 50%; (the value was 100% for center the modal)
    vertical-align: middle;
    margin-right: -4px;
  }

This may be overkill for what you're looking for, but there is an npm package called marky that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer. You just need to install it via npm and then import the dependency anywhere you'd like to use it. Here is a link to the npm package: https://www.npmjs.com/package/marky

An example of use after installing via npm would be as follows:

import * as _M from 'marky';

@Component({
 selector: 'app-test',
 templateUrl: './test.component.html',
 styleUrls: ['./test.component.scss']
})

export class TestComponent implements OnInit {
 Marky = _M;
}

constructor() {}

ngOnInit() {}

startTimer(key: string) {
 this.Marky.mark(key);
}

stopTimer(key: string) {
 this.Marky.stop(key);
}

key is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.

put only :

or die(mysqli_error());

after your query

and it will retern the error as echo

example

// "Your Query" means you can put "Select/Update/Delete/Set" queries here
$qfetch = mysqli_fetch_assoc(mysqli_query("your query")) or die(mysqli_error()); 



    if (mysqli_errno()) {
        echo 'error' . mysqli_error();
        die();
    }

Change jQueryUI to version 1.11.4 and make sure jQuery is not added twice.

Properties in your object are value types and you can use the shallow copy in such situation like that:

obj myobj2 = (obj)myobj.MemberwiseClone();

But in other situations, like if any members are reference types, then you need Deep Copy. You can get a deep copy of an object using Serialization and Deserialization techniques with the help of BinaryFormatter class:

public static T DeepCopy<T>(T other)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter formatter = new BinaryFormatter();
        formatter.Context = new StreamingContext(StreamingContextStates.Clone);
        formatter.Serialize(ms, other);
        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}

The purpose of setting StreamingContext: We can introduce special serialization and deserialization logic to our code with the help of either implementing ISerializable interface or using built-in attributes like OnDeserialized, OnDeserializing, OnSerializing, OnSerialized. In all cases StreamingContext will be passed as an argument to the methods(and to the special constructor in case of ISerializable interface). With setting ContextState to Clone, we are just giving hint to that method about the purpose of the serialization.

Additional Info: (you can also read this article from MSDN)

Shallow copying is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed; for a reference type, the reference is copied but the referred object is not; therefore the original object and its clone refer to the same object.

Deep copy is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed. If a field is a reference type, a new copy of the referred object is performed.

By default, hibernate framework will immediately return id , when you are trying to save the entity using Save(entity) method. There is no need to do it explicitly.

In case your primary key is int you can use below code:

int id=(Integer) session.save(entity);

In case of string use below code:

String str=(String)session.save(entity);

Sometimes it is possible to have most of implementation hidden in cpp file, if you can extract common functionality foo all template parameters into non-template class (possibly type-unsafe). Then header will contain redirection calls to that class. Similar approach is used, when fighting with "template bloat" problem.

As others have noted, in the instance you are asking about it is the destructor for class Stack.

But taking your question exactly as it appears in the title:

In c++ what does a tilde “~” before a function name signify?

there is another situation. In any context except immediately before the name of a class (which is the destructor context), ~ is the one's complement (or bitwise not) operator. To be sure it does not come up very often, but you can imagine a case like

if (~getMask()) { ...

which looks similar, but has a very different meaning.

Consider using a Spinner instead of a Number Picker in a Dialog. It's not exactly what was asked for, but it's much easier to implement, more contextual UI design, and should fulfill most use cases. The equivalent code for a Spinner is:

Spinner picker = new Spinner(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, yourStringList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
picker.setAdapter(adapter);

String someString = "" + c;
char c = someString.charAt(0);

You can achieve this by doing the following steps:

1. Make the parent view(content view of your activity) clickable and focusable by adding the following attributes

       android:clickable="true" 
       android:focusableInTouchMode="true" 
   

2. Implement a hideKeyboard() method

       public void hideKeyboard(View view) {
           InputMethodManager inputMethodManager =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
           inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
       }
   

3. Lastly, set the onFocusChangeListener of your edittext.

       edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
           @Override
           public void onFocusChange(View v, boolean hasFocus) {
               if (!hasFocus) {
                   hideKeyboard(v);
               }
           }
       });
   

As pointed out in one of the comments below, this might not work if the parent view is a ScrollView. For such case, the clickable and focusableInTouchMode may be added on the view directly under the ScrollView.

Downloading Wget is not necessary; the .NET Framework has web client classes built in.

$wc = New-Object system.Net.WebClient;
$sms = Read-Host "Enter SMS text";
$sms = [System.Web.HttpUtility]::UrlEncode($sms);
$smsResult = $wc.downloadString("http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$sms&encoding=windows-1255")

using (StreamWriter writer = File.AppendText(LoggingPath))
{
    writer.WriteLine("Text");
}

>>> str(10)
'10'
>>> int('10')
10

Links to the documentation:

• int()
• str()

Conversion to a string is done with the builtin str() function, which basically calls the __str__() method of its parameter.

... You can then use copy() to duplicate a PHP file, although this sounds incredibly inefficient.

I could solve the issue with the following steps

1. Install Maven separately
   https://www.mkyong.com/maven/how-to-install-maven-in-windows/
   
2. Set the external Maven installation in Eclipse
   

3. Set the proxy in settings.xml in Maven installation
(C:\path\apache-maven-3.6.0\conf)

<proxy>
 <id>optional</id>
 <active>true</active>
 <protocol>http</protocol>
 <username>optional-proxyuser</username>
 <password>optional-proxypass</password>
 <host>proxy.host.net</host>
 <port>80</port>
 <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>

4. Update the Maven User Settings

5. Update Maven project
   

Since you're accessing a web.config you should probably use

using System.Web.Configuration;

WebConfigurationManager.AppSettings["configFile"]

You can use '?' to set custom parameters in string using PreparedStatments.

statement =con.prepareStatement("SELECT * from employee WHERE  userID = ?");
statement.setString(1, userID);
ResultSet rs = statement.executeQuery();

If you directly pass userID in query as you are doing then it may get attacked by SQL INJECTION Attack.

Resetting the perspective wasn't quite enough for me, I had to first delete the "Variables" tab and then reset the perspective (which reinstated the Variables tab in a working state). One other thing not mentioned above which might help others - when the variables tab is not working, the tab title is in italics (whatever that signifies). When it's working it goes back to normal font.

If you want to save your numpy array (e.g. your_array = np.array([[1,2],[3,4]])) to one cell, you could convert it first with your_array.tolist().

Then save it the normal way to one cell, with delimiter=';' and the cell in the csv-file will look like this [[1, 2], [2, 4]]

Then you could restore your array like this: your_array = np.array(ast.literal_eval(cell_string))

Mario Gleichman describes how to use Java 1.5 generic functions to simulate Scala List literals, though sadly you wind up with immutable Lists.

He defines this class:

package literal;

public class collection {
    public static <T> List<T> List(T...elems){
        return Arrays.asList( elems );
    }
}

and uses it thusly:

import static literal.collection.List;
import static system.io.*;

public class CollectionDemo {
    public void demoList(){
        List<String> slist = List( "a", "b", "c" );
        List<Integer> iList = List( 1, 2, 3 );
        for( String elem : List( "a", "java", "list" ) )
            System.out.println( elem );
    }
}

Google Collections, now part of Guava supports a similar idea for list construction. In this interview, Jared Levy says:

[...] the most heavily-used features, which appear in almost every Java class I write, are static methods that reduce the number of repetitive keystrokes in your Java code. It's so convenient being able to enter commands like the following:

Map<OneClassWithALongName, AnotherClassWithALongName> = Maps.newHashMap();

List<String> animals = Lists.immutableList("cat", "dog", "horse");

7/10/2014: If only it could be as simple as Python's:

animals = ['cat', 'dog', 'horse']

2/21/2020: In Java 11 you can now say:

animals = List.of(“cat”, “dog”, “horse”)

cursor.rowcount will usually be set to 0.

If, however, you are running a statement that would never return a result set (such as INSERT without RETURNING, or SELECT ... INTO), then you do not need to call .fetchall(); there won't be a result set for such statements. Calling .execute() is enough to run the statement.

Note that database adapters are also allowed to set the rowcount to -1 if the database adapter can't determine the exact affected count. See the PEP 249 Cursor.rowcount specification:

The attribute is -1 in case no .execute*() has been performed on the cursor or the rowcount of the last operation is cannot be determined by the interface.

The sqlite3 library is prone to doing this. In all such cases, if you must know the affected rowcount up front, execute a COUNT() select in the same transaction first.

Sometimes you get the error because the destination location in phone are not exist. For example, some android phone external storage location is /storage/emulated/legacy instead of /storage/emulated/0.

The alternative, if you don't want to install libjpeg:

CFLAGS="--disable-jpeg" pip install pillow

Make it a block first, then float left to stop pushing the next block in to a new line.

#report-upload-form label {
                           padding-left:26px;
                           width:125px;
                           text-transform: uppercase;
                           display:block;
                           float:left
}

I can show you how I used it

  function GetDenierValue() {
        var denierid = $("#productDenierid").val() == '' ? 0 : $("#productDenierid").val();
        var param = { 'productDenierid': denierid };
        $.ajax({
            url: "/Admin/ProductComposition/GetDenierValue",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            type: "POST",
            data: JSON.stringify(param),
            success: function (msg) {
                if (msg != null) {
                    return msg.URL;
                }
            }
        });
    }

That should work. Better if you pass a function to val:

$('#replyBox').val(function(i, text) {
    return text + quote;
});

This way you avoid searching the element and calling val twice.

1. for error: unescaped apostrophe in string

In Android Studio, in problem file use :

Edit->find->replace

Then write in first field \' (or \&,>,\<,\")
in second put '(or &,>,<,")
then replace each if needed.(or "reptlace all" in case with ')
Then in first field again put '(or &,>,<,")
and in second write \'
then replace each if needed.(or "replace all" in case with ')

2. for other problematic symbols
I use to comment each next half part +rebuild until i won't find the wrong sign.

E.g. an escaped word "\update" unexpectedly drops such error :)

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

There's also a C standard built-in library to get command line arguments: getopt

You can check it on Wikipedia or in Argument-parsing helpers for C/Unix.

Quit the Android Studio ( not close the project Quit the Android Studio) then open the project and go to Android Studio > Build > Clean Project

Then Android Studio > File > Sync Project with Gradles Files as the pic below

If your problem still exists then click the Install build tool as the pic below and then Android Studio > File > Sync Project with Gradles Files

Yes there is such a built-in function: os.path.join.

>>> import os.path
>>> os.path.join('/my/root/directory', 'in', 'here')
'/my/root/directory/in/here'

I'm going to add one suggestion here. You can do this which avoids having to get any external libraries.

Give this a try:

String urlStr = "http://abc.dev.domain.com/0007AC/ads/800x480 15sec h.264.mp4";
URL url = new URL(urlStr);
URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
url = uri.toURL();

You can see that in this particular URL, I need to have those spaces encoded so that I can use it for a request.

This takes advantage of a couple features available to you in Android classes. First, the URL class can break a url into its proper components so there is no need for you to do any string search/replace work. Secondly, this approach takes advantage of the URI class feature of properly escaping components when you construct a URI via components rather than from a single string.

The beauty of this approach is that you can take any valid url string and have it work without needing any special knowledge of it yourself.

Because some database can throw an exception at dbContextTransaction.Commit() so better this:

using (var context = new BloggingContext()) 
{ 
  using (var dbContextTransaction = context.Database.BeginTransaction()) 
  { 
    try 
    { 
      context.Database.ExecuteSqlCommand( 
          @"UPDATE Blogs SET Rating = 5" + 
              " WHERE Name LIKE '%Entity Framework%'" 
          ); 

      var query = context.Posts.Where(p => p.Blog.Rating >= 5); 
      foreach (var post in query) 
      { 
          post.Title += "[Cool Blog]"; 
      } 

      context.SaveChanges(false); 

      dbContextTransaction.Commit(); 

      context.AcceptAllChanges();
    } 
    catch (Exception) 
    { 
      dbContextTransaction.Rollback(); 
    } 
  } 
} 

The following is also working for me:

ssh <user>@<host>  "cat <filepath>"|pbcopy 

Swift 2.2+ and Swift 3 Update

Use the new #selector expression, which eliminates the need to use string literals making usage less error-prone. For reference:

Selector("keyboardDidHide:")

becomes

#selector(keyboardDidHide(_:))

See also: Swift Evolution Proposal

Note (Swift 4.0):

If using #selectoryou would need to mark the function as @objc

Example:

@objc func something(_ sender: UIButton)

This is a simple use \D+ regex and job done.
This select all chars except digits, no need to complicate

/\D+/

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

if (myList?.Any() == true) 
{
   ...
}

I find this the most convenient way. '== true' checks the value of the nullable bool implied by '?.Any()

For me it's work with that code (with jQuery):

var int       = null,
    fired     = false;

var longclickFilm = function($t) {
        $body.css('background', 'red');
    },
    clickFilm = function($t) {
        $t  = $t.clone(false, false);
        var $to = $('footer > div:first');
        $to.find('.empty').remove();
        $t.appendTo($to);
    },
    touchStartFilm = function(event) {
        event.preventDefault();
        fired     = false;
        int       = setTimeout(function($t) {
            longclickFilm($t);
            fired = true;
        }, 2000, $(this)); // 2 sec for long click ?
        return false;
    },
    touchEndFilm = function(event) {
        event.preventDefault();
        clearTimeout(int);
        if (fired) return false;
        else  clickFilm($(this));
        return false;
    };

$('ul#thelist .thumbBox')
    .live('mousedown touchstart', touchStartFilm)
    .live('mouseup touchend touchcancel', touchEndFilm);

IEEE 754 floating point is done in binary. There's no exact conversion from a given number of bits to a given number of decimal digits. 3 bits can hold values from 0 to 7, and 4 bits can hold values from 0 to 15. A value from 0 to 9 takes roughly 3.5 bits, but that's not exact either.

An IEEE 754 double precision number occupies 64 bits. Of this, 52 bits are dedicated to the significand (the rest is a sign bit and exponent). Since the significand is (usually) normalized, there's an implied 53^rd bit.

Now, given 53 bits and roughly 3.5 bits per digit, simple division gives us 15.1429 digits of precision. But remember, that 3.5 bits per decimal digit is only an approximation, not a perfectly accurate answer.

Many (most?) debuggers actually look at the contents of the entire register. On an x86, that's actually an 80-bit number. The x86 floating point unit will normally be adjusted to carry out calculations to 64-bit precision -- but internally, it actually uses a couple of "guard bits", which basically means internally it does the calculation with a few extra bits of precision so it can round the last one correctly. When the debugger looks at the whole register, it'll usually find at least one extra digit that's reasonably accurate -- though since that digit won't have any guard bits, it may not be rounded correctly.

The Flexible does the trick

new Container(
       child: Row(
         children: <Widget>[
            Flexible(
               child: new Text("A looooooooooooooooooong text"))
                ],
        ));

This is the official doc https://flutter.dev/docs/development/ui/layout#lay-out-multiple-widgets-vertically-and-horizontally on how to arrange widgets.

Remember that Flexible and also Expanded, should only be used within a Column, Row or Flex, because of the Incorrect use of ParentDataWidget.

The solution is not the mere Flexible

Here it is in one line, without having to retype any of the variables or their values:

fruitdict.update({k:v for k,v in locals().copy().iteritems() if k[:2] != '__' and k != 'fruitdict'})

Because floats and doubles cannot accurately represent the base 10 multiples that we use for money. This issue isn't just for Java, it's for any programming language that uses base 2 floating-point types.

In base 10, you can write 10.25 as 1025 * 10^-2 (an integer times a power of 10). IEEE-754 floating-point numbers are different, but a very simple way to think about them is to multiply by a power of two instead. For instance, you could be looking at 164 * 2^-4 (an integer times a power of two), which is also equal to 10.25. That's not how the numbers are represented in memory, but the math implications are the same.

Even in base 10, this notation cannot accurately represent most simple fractions. For instance, you can't represent 1/3: the decimal representation is repeating (0.3333...), so there is no finite integer that you can multiply by a power of 10 to get 1/3. You could settle on a long sequence of 3's and a small exponent, like 333333333 * 10^-10, but it is not accurate: if you multiply that by 3, you won't get 1.

However, for the purpose of counting money, at least for countries whose money is valued within an order of magnitude of the US dollar, usually all you need is to be able to store multiples of 10^-2, so it doesn't really matter that 1/3 can't be represented.

The problem with floats and doubles is that the vast majority of money-like numbers don't have an exact representation as an integer times a power of 2. In fact, the only multiples of 0.01 between 0 and 1 (which are significant when dealing with money because they're integer cents) that can be represented exactly as an IEEE-754 binary floating-point number are 0, 0.25, 0.5, 0.75 and 1. All the others are off by a small amount. As an analogy to the 0.333333 example, if you take the floating-point value for 0.1 and you multiply it by 10, you won't get 1.

Representing money as a double or float will probably look good at first as the software rounds off the tiny errors, but as you perform more additions, subtractions, multiplications and divisions on inexact numbers, errors will compound and you'll end up with values that are visibly not accurate. This makes floats and doubles inadequate for dealing with money, where perfect accuracy for multiples of base 10 powers is required.

A solution that works in just about any language is to use integers instead, and count cents. For instance, 1025 would be $10.25. Several languages also have built-in types to deal with money. Among others, Java has the BigDecimal class, and C# has the decimal type.

It depends on the language. While you can possibly check a boolean variable here:

for (int i = 0; i < 100 && stayInLoop; i++) { ... }

it is not possible to do it when itering over an array:

for element in bigList: ...

Anyway, break would make both codes more readable.

You need to use an explicit color value (e.g. #000 or blue) for the color-property. none is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active, too.

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (
      'wpseo_title' => 'test',
      'wpseo_desc' => 'test',
      'wpseo_metakey' => 'test'
    );

// for recipe

$md_array["recipe_type"][] = $newdata;

//for cuisine

 $md_array["cuisine"][] = $newdata;

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);

I think this is a very useful question with good answer. Just to add my two cents from the MSDN Create a Login page:

A login is a security principal, or an entity that can be authenticated by a secure system. Users need a login to connect to SQL Server. You can create a login based on a Windows principal (such as a domain user or a Windows domain group) or you can create a login that is not based on a Windows principal (such as an SQL Server login).

Note:
To use SQL Server Authentication, the Database Engine must use mixed mode authentication. For more information, see Choose an Authentication Mode.

As a security principal, permissions can be granted to logins. The scope of a login is the whole Database Engine. To connect to a specific database on the instance of SQL Server, a login must be mapped to a database user. Permissions inside the database are granted and denied to the database user, not the login. Permissions that have the scope of the whole instance of SQL Server (for example, the CREATE ENDPOINT permission) can be granted to a login.

If you have a custom.css file, in there, just do something like:

font-family: "Oswald", Helvetica, Arial, sans-serif!important;

Depends on application, really.

Consider setting a timestamp by a user to a server in New York, for an appointment in Sanghai. Now when the user connects in Sanghai, he accesses the same appointment timestamp from a mirrored server in Tokyo. He will see the appointment in Tokyo time, offset from the original New York time.

So for values that represent user time like an appointment or a schedule, datetime is better. It allows the user to control the exact date and time desired, regardless of the server settings. The set time is the set time, not affected by the server's time zone, the user's time zone, or by changes in the way daylight savings time is calculated (yes it does change).

On the other hand, for values that represent system time like payment transactions, table modifications or logging, always use timestamps. The system will not be affected by moving the server to another time zone, or when comparing between servers in different timezones.

Timestamps are also lighter on the database and indexed faster.

Well, techincally you can…

typedef struct { char xx[18]; } arr_wrap;

char array1[18] = "abcdefg";
char array2[18];

*((arr_wrap *) array2) = *((arr_wrap *) array1);

printf("%s\n", array2);     /* "abcdefg" */

but it will not look very beautiful.

…Unless you use the C preprocessor…

#define CC_MEMCPY(DESTARR, SRCARR, ARRSIZE) \
    { struct _tmparrwrap_ { char xx[ARRSIZE]; }; *((struct _tmparrwrap_ *) DESTARR) = *((struct _tmparrwrap_ *) SRCARR); }

You can then do:

char array1[18] = "abcdefg";
char array2[18];

CC_MEMCPY(array2, array1, sizeof(array1));

printf("%s\n", array2);     /* "abcdefg" */

And it will work with any data type, not just char:

int numbers1[3] = { 1, 2, 3 };
int numbers2[3];

CC_MEMCPY(numbers2, numbers1, sizeof(numbers1));

printf("%d - %d - %d\n", numbers2[0], numbers2[1], numbers2[2]);     /* "abcdefg" */

(Yes, the code above is granted to work always and it's portable)

I use classnames when there is a fair amount of logic required for deciding the classes to (not) use. An overly simple example:

...
    var liClasses = classNames({
      'main-class': true,
      'activeClass': self.state.focused === index
    });

    return (<li className={liClasses}>{data.name}</li>);
...

That said, if you don't want to include a dependency then there are better answers below.

So close! os.path.isdir returns True if you pass in the name of a directory that currently exists. If it doesn't exist or it's not a directory, then it returns False.

Do you want to wait for them to finish? If so, use the Join method.

There is also the isAlive property if you just want to check it.

There's no easy way to do it. This is kind of the point of hashing the password in the first place. :)

One thing you should be able to do is set a temporary password for them manually and send them that.

I hesitate to mention this because it's a bad idea (and it's not guaranteed to work anyway), but you could try looking up the hash in a rainbow table like milw0rm to see if you can recover the old password that way.

Try using white-space: nowrap; in the container style (instead of overflow: hidden;)

Brief Introduction

When using Anaconda, one needs to be aware of the environment that one is working.

Then, in Anaconda Prompt (base) one needs to use the following code:

conda $command -n $ENVIRONMENT_NAME $IDE/package/module

$command - Command that I intend to use (consult documentation for general commands)

$ENVIRONMENT NAME - The name of your environment (if one is working in the root, conda $command $IDE/package/module is enough)

$IDE/package/module - The name of the IDE or package or module

Solution

If one wants to install it in the root and one follows the requirements - (Python (>= 2.7 or >= 3.4), NumPy (>= 1.8.2), SciPy (>= 0.13.3).) - the following will solve the problem:

conda install scikit-learn

Let's say that one is working in the environment with the name ML.

Then the following will solve one's problem:

conda install -n ML scikit-learn

Note: If one needs to install/update packages, the logic is the same as mentioned in the introduction. If you need more information on Anaconda Packages, check the documentation.

If the above doesn't work, on Anaconda Prompt one can also use pip (here's how to pip install scikit-learn) so the following may help

pip install scikit-learn

Fix memory leaks in your application with help of profile tools like eclipse MAT or VisualVM

With JDK 1.7.x or later versions, use G1GC, which spends 10% on garbage collection unlike 2% in other GC algorithms.

Apart from setting heap memory with -Xms1g -Xmx2g , try `

-XX:+UseG1GC 
-XX:G1HeapRegionSize=n, 
-XX:MaxGCPauseMillis=m, 
-XX:ParallelGCThreads=n, 
-XX:ConcGCThreads=n`

Have a look at oracle article for fine-tuning these parameters.

Some question related to G1GC in SE:

Java 7 (JDK 7) garbage collection and documentation on G1

Get the current Windows username:

using System;

class Sample
{
    public static void Main()
    {
        Console.WriteLine();

        //  <-- Keep this information secure! -->
        Console.WriteLine("UserName: {0}", Environment.UserName);
    }
}

You can try these below views.

SELECT * FROM USER_SYS_PRIVS; 
SELECT * FROM USER_TAB_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;

DBAs and other power users can find the privileges granted to other users with the DBA_ versions of these same views. They are covered in the documentation .

Those views only show the privileges granted directly to the user. Finding all the privileges, including those granted indirectly through roles, requires more complicated recursive SQL statements:

select * from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER' order by 1,2,3;
select * from dba_sys_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3;
select * from dba_tab_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3,4;

None of the above worked for me on Ubuntu 12.04 LTS (Precise Pangolin), and here's how I fixed it in the end:

Download ez_setup.py from download setuptools (see "Installation Instructions" section) then:

$ sudo python ez_setup.py

I hope it saves someone some time.

Use:

>>> str_float = "545.2222"
>>> float(str_float)
545.2222
>>> type(_) # Check its type
<type 'float'>

>>> str_int = "31"
>>> int(str_int)
31
>>> type(_) # Check its type
<type 'int'>

This should help.

Integer startIn = null;

// (optional below but a good practice, to prevent errors.)
boolean dontContinue = false;
try {
  Integer.parseInt (startField.getText());
} catch (NumberFormatException e){
  e.printStackTrace();
}

// in java = assigns a boolean in if statements oddly.
// Thus double equal must be used. So if startIn is null, display the message
if (startIn == null) {
  JOptionPane.showMessageDialog(null,
       "You must enter a number between 0-16.","Input Error",
       JOptionPane.ERROR_MESSAGE);                            
}

// (again optional)
if (dontContinue == true) {
  //Do-some-error-fix
}

You can use cv2.rectangle():

cv2.rectangle(img, pt1, pt2, color, thickness, lineType, shift)

Draws a simple, thick, or filled up-right rectangle.

The function rectangle draws a rectangle outline or a filled rectangle
whose two opposite corners are pt1 and pt2.

Parameters
    img   Image.
    pt1   Vertex of the rectangle.
    pt2    Vertex of the rectangle opposite to pt1 .
    color Rectangle color or brightness (grayscale image).
    thickness  Thickness of lines that make up the rectangle. Negative values,
    like CV_FILLED , mean that the function has to draw a filled rectangle.
    lineType  Type of the line. See the line description.
    shift   Number of fractional bits in the point coordinates.

I have a PIL Image object and I want to draw rectangle on this image, but PIL's ImageDraw.rectangle() method does not have the ability to specify line width. I need to convert Image object to opencv2's image format and draw rectangle and convert back to Image object. Here is how I do it:

# im is a PIL Image object
im_arr = np.asarray(im)
# convert rgb array to opencv's bgr format
im_arr_bgr = cv2.cvtColor(im_arr, cv2.COLOR_RGB2BGR)
# pts1 and pts2 are the upper left and bottom right coordinates of the rectangle
cv2.rectangle(im_arr_bgr, pts1, pts2,
              color=(0, 255, 0), thickness=3)
im_arr = cv2.cvtColor(im_arr_bgr, cv2.COLOR_BGR2RGB)
# convert back to Image object
im = Image.fromarray(im_arr)

I think someone should face the same problem that can't find out the branch, although it actually exists in one branch.

You'd better pull all first:

git pull --all

Then do the branch search:

git name-rev <SHA>

or:

git branch --contains <SHA>

Here is an example. Imagine that you are going to put the files and directory names (under the current folder) to an array and count its items. The script would be like;

my_array=( `ls` )
my_array_length=${#my_array[@]}
echo $my_array_length

Or, you can iterate over this array by adding the following script:

for element in "${my_array[@]}"
do
   echo "${element}"
done

Please note that this is the core concept and the input is considered to be sanitized before, i.e. removing extra characters, handling empty Strings, and etc. (which is out of the topic of this thread).

window.open is a method; you can open new window, and can customize it. window.location.href is just a property of the current window.

Instead of using regexp_replace multiple time use (\s) as given below;

SELECT regexp_replace('TEXT','(\s)','')
FROM dual;

For those of you who would rather not go with Regex and are on the .NET 2.0 Framework (AKA no LINQ):

Only Letters:

public static bool IsAllLetters(string s)
{
    foreach (char c in s)
    {
        if (!Char.IsLetter(c))
            return false;
    }
    return true;
}

Only Numbers:

    public static bool IsAllDigits(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsDigit(c))
                return false;
        }
        return true;
    }

Only Numbers Or Letters:

    public static bool IsAllLettersOrDigits(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsLetterOrDigit(c))
                return false;
        }
        return true;
    }

Only Numbers Or Letters Or Underscores:

    public static bool IsAllLettersOrDigitsOrUnderscores(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsLetterOrDigit(c) && c != '_')
                return false;
        }
        return true;
    }

Checking the Options Over Write Database worked for me :)

This should be consistent with how Q does it:

if(!Promise.allSettled) {
    Promise.allSettled = function (promises) {
        return Promise.all(promises.map(p => Promise.resolve(p).then(v => ({
            state: 'fulfilled',
            value: v,
        }), r => ({
            state: 'rejected',
            reason: r,
        }))));
    };
}

let hour = date.hour   // 15

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

What's not mentioned here is that option 1 allows you arbitrarily deep nesting of lists.

This shouldn't matter if you control the content/css, but if you're making a rich text editor it comes in handy.

For example, gmail, inbox, and evernote all allow creating lists like this:

With option 2 you cannot due that (you'll have an extra list item), with option 1, you can.

df.drop(labels=df[df.index % 3 != 0].index, axis=0) #  every 3rd row (mod 3)

C++ community has heard your request :)

C++ 20 provides an easy way of doing it now. It gets as simple as :

#include <vector>
...
vector<int> cnt{5, 0, 2, 8, 0, 7};
std::erase(cnt, 0);

You should check out std::erase and std::erase_if.

Not only will it remove all elements of the value (here '0'), it will do it in O(n) time complexity. Which is the very best you can get.

If your compiler does not support C++ 20, you should use erase-remove idiom:

#include <algorithm>
...
vec.erase(std::remove(vec.begin(), vec.end(), 0), vec.end());

With Yglu Structural Templating, your example can be written:

foo: !()
  !? $.propname: 
     type: number 
     default: !? $.default

bar:
  !apply .foo: 
    propname: "some_prop"
    default: "some default"

Disclaimer: I am the author or Yglu.

As I mentioned in your other question:

The problem to do with that fact, that you invented your own non-standard attributes (which you shouldn't have done in the first place), and now new standardized attributes (or attributes in the process of being standardized) are colliding with them.

The proper solution is to completely remove your invented attributes and replace them with something sensible, for example classes (class="Montantetextfield fieldname-Montante required allow-decimal-values"), or store them in JavaScript:

var validationData = {
  "Montante": {fieldname: "Montante", required: true, allowDecimalValues: true}
}

If the proper solution isn't viable, you'll have to rename them. In that case you should use the prefix data-... because that is reserved by HTML5 for such purposes, and it's less likely to collide with something - but it still could, so you should seriously consider the first solution - even it is more work to change.

I display images in windows forms when I put it in Load event like this:

    private void Form1_Load( object sender , EventArgs e )
    {
        pictureBox1.ImageLocation = "./image.png"; //path to image
        pictureBox1.SizeMode = PictureBoxSizeMode.AutoSize;
    }

If you want to measure time in microseconds, then you can use the following version, based completely on the answers of Paul McGuire and Nicojo - it's Python 3 code. I've also added some colour to it:

import atexit
from time import time
from datetime import timedelta, datetime


def seconds_to_str(elapsed=None):
    if elapsed is None:
        return datetime.now().strftime("%Y-%m-%d %H:%M:%S.%f")
    else:
        return str(timedelta(seconds=elapsed))


def log(txt, elapsed=None):
    colour_cyan = '\033[36m'
    colour_reset = '\033[0;0;39m'
    colour_red = '\033[31m'
    print('\n ' + colour_cyan + '  [TIMING]> [' + seconds_to_str() + '] ----> ' + txt + '\n' + colour_reset)
    if elapsed:
        print("\n " + colour_red + " [TIMING]> Elapsed time ==> " + elapsed + "\n" + colour_reset)


def end_log():
    end = time()
    elapsed = end-start
    log("End Program", seconds_to_str(elapsed))


start = time()
atexit.register(end_log)
log("Start Program")

log() => function that prints out the timing information.

txt ==> first argument to log, and its string to mark timing.

atexit ==> Python module to register functions that you can call when the program exits.

Because the range for floats is greater than that of integers -- returning an integer could overflow

It is possible to increase heap size allocated by the JVM by using command line options Here we have 3 options

-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

java -Xms16m -Xmx64m ClassName

In the above line we can set minimum heap to 16mb and maximum heap 64mb

I had a similar issue.

Cause:

import HomeComponent from "components/HomeComponent";

Solution:

import HomeComponent from "./components/HomeComponent";

NOTE: ./ was before components. You can read @Zac Kwan's post above on how to use import

With the Return statement from the proc, I needed to assign the temp variable and pass it to another stored procedure. The value was getting assigned fine but when passing it as a parameter, it lost the value. I had to create a temp table and set the variable from the table (SQL 2008)

From this: 
declare @anID int
exec @anID = dbo.StoredProc_Fetch @ID, @anotherID, @finalID
exec dbo.ADifferentStoredProc @anID (no value here)

To this:
declare @t table(id int) 
declare @anID int
insert into @t exec dbo.StoredProc_Fetch @ID, @anotherID, @finalID
set @anID= (select Top 1 * from @t)

You are probably trying to create nested directories. Assuming foo does not exist, you will receive no such file or directory error for:

Dir.mkdir 'foo/bar'
# => Errno::ENOENT: No such file or directory - 'foo/bar'

To create nested directories at once, FileUtils is needed:

require 'fileutils'
FileUtils.mkdir_p 'foo/bar'
# => ["foo/bar"]

Edit2: you do not have to use FileUtils, you may do system call (update from @mu is too short comment):

> system 'mkdir', '-p', 'foo/bar' # worse version: system 'mkdir -p "foo/bar"'
=> true

But that seems (at least to me) as worse approach as you are using external 'tool' which may be unavailable on some systems (although I can hardly imagine system without mkdir, but who knows).

Interestingly, both C & C++ (and I think C#, but I'm not sure) specifically allow the trailing comma -- for exactly the reason given: It make programmaticly generating lists much easier. Not sure why JavaScript didn't follow their lead.

I think the only way to handle this is to use JavaScript

Try this Invert text color of a specific element

If you do this with css3 it's only compatible with the newest browser versions.

Try this. This method will determine if (two) date spans are overlapping, regardless of the ordering of the method's input arguments. This can also be used with more than two date spans, by individually checking each date span combination (ex. with 3 date spans, run span1 against span2, span2 against span3, and span1 against span3):

MSDN information: HttpRuntimeSection.RequestValidationMode Property

The solution would be,

Console.Beep

The terminal is not case sensitive when writing "Javac [x].java", so make sure what you write in the terminal matches the filename and class name.

My class name and file name were both "MainClass", but I was compiling using "Mainclass". Notice I forgot to make the "c" capital.

After exiting eclipse I moved .eclipse (found in the user's home directory) to .eclipse.old (just in case I may have had to undo). The error does not show up any more and my projects are working fine after restarting eclipse.

Caution: I have a simple setup and this may not be the best for environments with advanced settings.

I am posting this as a separate answer as previously listed methods did not work for me.

Write it as below

<script language="javascript">
var visitorName = 'Chuck';
var myOldString = 'Hello username. I hope you enjoy your stay username.';

var myNewString = myOldString.replace('username', visitorName);

document.write('Old String = ' + myOldString);
document.write('<br/>New string = ' + myNewString);

How a connection works in a nutshell

A connection between a program and a database server relies on a handshake.

What this means is that when a connection is opened then the thread establishing the connection will send network packets to the database server. This thread will then pause until either network packets about this connection are received from the database server or when the connection timeout expires.

The connection timeout

The connection timeout is measured in seconds from the point the connection is opened.

When the timeout expires then the thread will continue, but it will do so having reported a connection failure.

• If there is no value specified for connection timeout in the connection string then the default value is 30.

• A value greater than zero means how many seconds before it gives up e.g. a value of 10 means to wait 10 seconds.

• A value of 0 means to never give up waiting for the connection

Note: A value of 0 is not advised since it is possible for either the connection request packets or the server response packets to get lost. Will you seriously be prepared to wait even a day for a response that may never come?

What should I set my Connection Timeout value to?

This setting should depend on the speed of your network and how long you are prepared to allow a thread to wait for a response.

As an example, on a task that repeats hourly during the day, I know my network has always responded within one second so I set the connection timeout to a value of 2 just to be safe. I will then try again three times before giving up and either raising a support ticket or escalating a similar existing support ticket.

Test your own network speed and consider what to do when a connection fails as a one off, and also when it fails repeatedly and sporadically.

First check if your wlan card support hosted network and if no update the card driver. Follow this steps

1) open cmd with administrative rights
2) on the black screen type: netsh wlan show driver | findstr Hosted
3) See Hosted network supported, if No then update drivers

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

OK. After trying out some error handling, I figured out how to solve the issue I was having.

Here's an example of how to make this work (let me know if there's something I'm missing) :

SET XACT_ABORT OFF ; -- > really important to set that to OFF
BEGIN
DECLARE @Any_error int
DECLARE @SSQL varchar(4000)
BEGIN TRANSACTION
    INSERT INTO Table1(Value1) VALUES('Value1')
    SELECT @Any_error = @@ERROR
    IF @Any_error<> 0 AND @Any_error<>2627 GOTO ErrorHandler

    INSERT INTO Table1(Value1) VALUES('Value1')
    SELECT @Any_error = @@ERROR
    IF @Any_error<> 0 AND @Any_error<>2627 GOTO ErrorHandler

    INSERT INTO Table1(Value1) VALUES('Value2')
    SELECT @Any_error = @@ERROR
    IF @Any_error<> 0 AND @Any_error<>2627 GOTO ErrorHandler

    ErrorHandler: 
       IF @Any_error = 0 OR @Any_error=2627
       BEGIN 
           PRINT @ssql 
           COMMIT TRAN
       END
       ELSE 
       BEGIN 
           PRINT @ssql 
           ROLLBACK TRAN 
       END
END

As a result of the above Transaction, Table1 will have the following values Value1, Value2.

2627 is the error code for Duplicate Key by the way.

Thank you all for the prompt reply and helpful suggestions.

Adding to the answer of stackoverflowuser2010, in the general case you can just use

data = np.array([[1,1,1],[2,2,2],[3,3,3]])

vector = np.array([1,2,3])

data / vector.reshape(-1,1)

This will turn your vector into a column matrix/vector. Allowing you to do the elementwise operations as you wish. At least to me, this is the most intuitive way going about it and since (in most cases) numpy will just use a view of the same internal memory for the reshaping it's efficient too.

I was able to solve a problem similar to this in Visual Studio 2010 by using NuGet.

Go to Tools > Library Package Manager > Manage NuGet Packages For Solution...

In the dialog, search for "EntityFramework.SqlServerCompact". You'll find a package with the description "Allows SQL Server Compact 4.0 to be used with Entity Framework." Install this package.

An element similar to the following will be inserted in your web.config:

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
    <parameters>
      <parameter value="System.Data.SqlServerCe.4.0" />
    </parameters>
  </defaultConnectionFactory>
</entityFramework>

The first thing is to understand that, the Dispatcher is not designed to run long blocking operation (such as retrieving data from a WebServer...). You can use the Dispatcher when you want to run an operation that will be executed on the UI thread (such as updating the value of a progress bar).

What you can do is to retrieve your data in a background worker and use the ReportProgress method to propagate changes in the UI thread.

If you really need to use the Dispatcher directly, it's pretty simple:

Application.Current.Dispatcher.BeginInvoke(
  DispatcherPriority.Background,
  new Action(() => this.progressBar.Value = 50));

You shouldn't use the control private tooltip, but the form one. This example works well:

public partial class Form1 : Form
{
    private System.Windows.Forms.ToolTip toolTip1;

    public Form1()
    {
        InitializeComponent();
        this.components = new System.ComponentModel.Container();
        this.toolTip1 = new System.Windows.Forms.ToolTip(this.components);

        MyRitchTextBox myRTB = new MyRitchTextBox();
        this.Controls.Add(myRTB);

        myRTB.Location = new Point(10, 10);
        myRTB.MouseEnter += new EventHandler(myRTB_MouseEnter);
        myRTB.MouseLeave += new EventHandler(myRTB_MouseLeave);
    }


    void myRTB_MouseEnter(object sender, EventArgs e)
    {
        MyRitchTextBox rtb = (sender as MyRitchTextBox);
        if (rtb != null)
        {
            this.toolTip1.Show("Hello!!!", rtb);
        }
    }

    void myRTB_MouseLeave(object sender, EventArgs e)
    {
        MyRitchTextBox rtb = (sender as MyRitchTextBox);
        if (rtb != null)
        {
            this.toolTip1.Hide(rtb);
        }
    }


    public class MyRitchTextBox : RichTextBox
    {
    }

}

This is simply not allowed:

Type key = message.GetType();
MessageProcessor<key> processor = messageProcessors[key] as MessageProcessor<key>;

You cannot get a generic type as a variable value.

You'd have to do a switch or something:

Type key = message.GetType();
if (key == typeof(Foo))
{
    MessageProcessor<Foo> processor = (MessageProcessor<Foo>)messageProcessors[key];
    // Do stuff with processor
}
else if (key == typeof(Bar))
{
    MessageProcessor<bar> processor = (MessageProcessor<Bar>)messageProcessors[key];
    // Do stuff with processor
}
...

If you're more used to using ax objects to do your plotting, you might find the ax.xaxis.label.set_size() easier to remember, or at least easier to find using tab in an ipython terminal. It seems to need a redraw operation after to see the effect. For example:

import matplotlib.pyplot as plt

# set up a plot with dummy data
fig, ax = plt.subplots()
x = [0, 1, 2]
y = [0, 3, 9]
ax.plot(x,y)

# title and labels, setting initial sizes
fig.suptitle('test title', fontsize=12)
ax.set_xlabel('xlabel', fontsize=10)
ax.set_ylabel('ylabel', fontsize='medium')   # relative to plt.rcParams['font.size']

# setting label sizes after creation
ax.xaxis.label.set_size(20)
plt.draw()

I don't know of a similar way to set the suptitle size after it's created.

You are close, but the parameter you pass to SecureStringToBSTR must be a SecureString. You appear to be passing the result of ConvertFrom-SecureString, which is an encrypted standard string. So call ConvertTo-SecureString on this before passing to SecureStringToBSTR.

$SecurePassword = ConvertTo-SecureString $PlainPassword -AsPlainText -Force
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecurePassword)
$UnsecurePassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)

Read file, parse each line into an integer and store into a list:

List<Integer> list = new ArrayList<Integer>();
File file = new File("file.txt");
BufferedReader reader = null;

try {
    reader = new BufferedReader(new FileReader(file));
    String text = null;

    while ((text = reader.readLine()) != null) {
        list.add(Integer.parseInt(text));
    }
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        if (reader != null) {
            reader.close();
        }
    } catch (IOException e) {
    }
}

//print out the list
System.out.println(list);

You have multiple ways to do this.

1:

location.href;

2:

document.URL;

3:

document.documentURI;

Everytime I use another approach. People seem to store or get position on a view, rather than storing a reference to an object that is displayed by ViewHolder.

I use this approach instead, and just store it in ViewHolder when onBindViewHolder() is called, and set reference to null in onViewRecycled().

Every time ViewHolder becomes invisible, it's recycled. So this doesn't affect in large memory consumption.

@Override
public void onBindViewHolder(final ItemViewHolder holder, int position) {
    ...
    holder.displayedItem = adapterItemsList.get(i);
    ...
}

@Override
public void onViewRecycled(ItemViewHolder holder) {
    ...
    holder.displayedItem = null;
    ...
}

class ItemViewHolder extends RecyclerView.ViewHolder {
    ...
    MySuperItemObject displayedItem = null;
    ...
}

This notation (first seen here) looks useful too:

insert into postagem (
  resumopostagem,
  textopostagem,
  dtliberacaopostagem,
  idmediaimgpostagem,
  idcatolico,
  idminisermao,
  idtipopostagem
) select

Look at git stash to put all of your local changes into a "stash file" and revert to the last commit. At that point, you can apply your stashed changes, or discard them.

Well if you are using Netbeans in Linux, then you should look for the tomcat-user.xml in

/home/Username/.netbeans/8.0/apache-tomcat-8.0.3.0_base/conf

(its called Catalina Base and is often hidden) instead of the Apache installation directory.

open tomcat-user.xml inside that folder, uncomment the user and roles and add/replace the following line.

    <user username="tomcat" password="tomcat" roles="tomcat,admin,admin-gui,manager,manager-gui"/>

restart the server . That's all

The language attribute has been deprecated for a long time, and should not be used.

When W3C was working on HTML5, they discovered all browsers have "text/javascript" as the default script type, so they standardized it to be the default value. Hence, you don't need type either.

For pages in XHTML 1.0 or HTML 4.01 omitting type is considered invalid. Try validating the following:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<script src="http://example.com/test.js"></script>
</head>
<body/>
</html>

You will be informed of the following error:

Line 4, Column 41: required attribute "type" not specified

So if you're a fan of standards, use it. It should have no practical effect, but, when in doubt, may as well go by the spec.

An alternative to cat() is writeLines():

> writeLines("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename
>

An advantage is that you don't have to remember to append a "\n" to the string passed to cat() to get a newline after your message. E.g. compare the above to the same cat() output:

> cat("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename>

and

> cat("File not supplied.\nUsage: ./program F=filename","\n")
File not supplied.
Usage: ./program F=filename
>

The reason print() doesn't do what you want is that print() shows you a version of the object from the R level - in this case it is a character string. You need to use other functions like cat() and writeLines() to display the string. I say "a version" because precision may be reduced in printed numerics, and the printed object may be augmented with extra information, for example.

Here's a solution, but I don't know if it's the best....

Select              
Coalesce(Case When Len(listing.Offer_Text) = 0 Then Null Else listing.Offer_Text End, company.Offer_Text, '') As Offer_Text,         
from tbl_directorylisting listing  
 Inner Join tbl_companymaster company            
  On listing.company_id= company.company_id

You could ignore SIGINTs after shutdown starts by calling signal.signal(signal.SIGINT, signal.SIG_IGN) before you start your cleanup code.

I was having the same error while I was doing AngularJS application. I did not see any error from my terminal but when I debug with google developer tool, I have got this error.

After having this error, I reviewed my routing module first , since I was not seeing anything while requesting local host /login.

I found out that I misspelled the login as lgin and when I correct it works fine. I am just sharing this just to pay attention for any typo error we might encounter with put us in a great time loose!

Here is another, very manual solution. You can define the size of the axis and paddings are considered accordingly (including legend and tickmarks). Hope it is of use to somebody.

Example (axes size are the same!):

         ,(1,0,1) #magenta
         ,(1,0.5,0.5) #pink
         ,(0.5,0.5,0.5) #gray

As many others have said, htmlentities() will do the trick... but it will look like shit.

Wrap it up with a <pre> tag and you'll preserve your indentation.

echo '<pre>';
echo htmlspecialchars($YOUR_HTML);
echo '</pre>';

Note the require-dev (root-only) !

which means that the require-dev section is only valid when your package is the root of the entire project. I.e. if you run composer update from your package folder.

If you develop a plugin for some main project, that has it's own composer.json, then your require-dev section will be completely ignored! If you need your developement dependencies, you have to move your require-dev to composer.json in main project.

A StringBuffer or its younger and faster brother StringBuilder is preferred whenever you're going do to a lot of string concatenations in flavor of

string += newString;

or equivalently

string = string + newString;

because the above constructs implicitly creates new string everytime which will be a huge performance and drop. A StringBuffer / StringBuilder is under the hoods best to be compared with a dynamically expansible List<Character>.

There is also http://appyframework.org/pod.html which takes a LibreOffice or OpenOffice document as template and can generate pdf, rtf, odt ... To generate pdf it requires a headless OOo on some server. Documentation is concise but relatively complete. http://appyframework.org/podWritingTemplates.html If you need advice, the author is rather helpful.

My rules:

1. Don't initialize with the default values in declaration (null, false, 0, 0.0…).
2. Prefer initialization in declaration if you don't have a constructor parameter that changes the value of the field.
3. If the value of the field changes because of a constructor parameter put the initialization in the constructors.
4. Be consistent in your practice (the most important rule).

As MDN's refs says, just need give a name of the new window/tab.

https://developer.mozilla.org/en-US/docs/Web/API/Window/open#Syntax

open in the current tab page using _self

<a
 href="url"
 target="_self">
   open
</a>

const autoOpenAlink = (url = ``) => {
  window.open(url, "open testing page in the same tab page");
}

open in a new tab page using _blank

vue demo

    <div style="margin: 5px;">
        <a
            :href="url"
            @click="autoOpenAlink"
            target="_blank"
            >
            {{url}}
        </a>
    </div>

vue

    autoOpenAlink(e) {
        e.preventDefault();
        let url = this.url;
        window.open(url, "iframe testing page");
    },

Vanilla JS solution:

var el = document.getElementById('changeProgramatic');
el.value='New Value'
el.dispatchEvent(new Event('change'));

Note that dispatchEvent doesn't work in old IE (see: caniuse). So you should probably only use it on internal websites (not on websites having wide audience).

So as of 2019 you just might want to make sure your customers/audience don't use Windows XP (yes, some still do in 2019). You might want to use conditional comments to warn customers that you don't support old IE (pre IE 11 in this case), but note that conditional comments only work until IE9 (don't work in IE10). So you might want to use feature detection instead. E.g. you could do an early check for: typeof document.body.dispatchEvent === 'function'.

This did reduce the size in my case:

ng build --prod --build-optimizer --optimization.

For Angular 5+ ng-build --prod does this by default. Size after running this command reduced from 1.7MB to 1.2MB, but not enough for my production purpose.

I work on facebook messenger platform and messenger apps need to be lesser than 1MB to run on messenger platform. Been trying to figure out a solution for effective tree shaking but still no luck.

YES, you can Update and Insert into view and that edit will be reflected on the original table....
BUT
1-the view should have all the NOT NULL values on the table
2-the update should have the same rules as table... "updating primary key related to other foreign key.. etc"...

Following code worked for me:

     git fetch
     git checkout <branch from which file needs to be fetched> <filepath> 

A shell script to accomplish this:

#!/bin/bash

# Remove whitespace
function remWS {
    if [ -z "${1}" ]; then
        cat | tr -d '[:space:]'
    else
        echo "${1}" | tr -d '[:space:]'
    fi
}

for pkg in $(adb shell pm list packages -3 | cut -d':' -f2); do
    apk_loc="$(adb shell pm path $(remWS $pkg) | cut -d':' -f2 | remWS)"
    apk_name="$(adb shell aapt dump badging $apk_loc | pcregrep -o1 $'application-label:\'(.+)\'' | remWS)"
    apk_info="$(adb shell aapt dump badging $apk_loc | pcregrep -o1 '\b(package: .+)')"

    echo "$apk_name v$(echo $apk_info | pcregrep -io1 -e $'\\bversionName=\'(.+?)\'')"
done

On Centos 5.3 I'm able to do:

mail -s "Subject" [email protected] -- -f [email protected] < body

The double dash stops mail from parsing the -f argument and passes it along to sendmail itself.

I would say, it depends.

If you develop a desktop application, where the OS works in Unicode (like all current Windows systems) and language does natively support Unicode (default strings are Unicode, like in Java or C#), then go nvarchar.

If you develop a web application, where strings come in as UTF-8, and language is PHP, which still does not support Unicode natively (in versions 5.x), then varchar will probably be a better choice.

Somehow all these solutions didn't work for me. There is clearly an IE bug in flex-direction:column.

I only got it working after removing flex-direction:

flex-wrap: wrap;
align-items: center;
align-content: center;

This technique was taught in an undergraduate level introduction-to-Java class I took over a decade ago. However, I should note that, IIRC, we hadn't yet gotten to the String and Integer class methods.

The technique is simple and quick to type. If all I'm doing is printing something, I'll use it (for example, System.out.println("" + i);. However, I think it's not the best way to do a conversion, as it takes a second of thought to realize what's going on when it's being used this way. Also, if performance is a concern, it seems slower (more below, as well as in other answers).

Personally, I prefer Integer.toString(), as it is obvious what's happening. String.valueOf() would be my second choice, as it seems to be confusing (witness the comments after darioo's answer).

Just for grins :) I wrote up classes to test the three techniques: "" + i, Integer.toString, and String.ValueOf. Each test just converted the ints from 1 to 10000 to Strings. I then ran each through the Linux time command five times. Integer.toString() was slightly faster than String.valueOf() once, they tied three times, and String.valueOf() was faster once; however, the difference was never more than a couple of milliseconds.

The "" + i technique was slower than both on every test except one, when it was 1 millisecond faster than Integer.toString() and 1 millisecond slower than String.valueOf() (obviously on the same test where String.valueOf() was faster than Integer.toString()). While it was usually only a couple milliseconds slower, there was one test where it was about 50 milliseconds slower. YMMV.

MAVEN_HOME is used for maven 1 and M2_HOME is used to locate maven 2. Having the two different _HOME variables means it is possible to run both on the same machine. And if you check old mvn.cmd scripts they have something like,

@REM ----------------------------------------------------------------------------
@REM Maven2 Start Up Batch script
@REM
@REM Required ENV vars:
@REM JAVA_HOME - location of a JDK home dir
@REM
@REM Optional ENV vars
@REM M2_HOME - location of maven2's installed home dir
@REM MAVEN_BATCH_ECHO - set to 'on' to enable the echoing of the batch commands
@REM MAVEN_BATCH_PAUSE - set to 'on' to wait for a key stroke before ending
@REM MAVEN_OPTS - parameters passed to the Java VM when running Maven
@REM     e.g. to debug Maven itself, use
@REM set MAVEN_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000
@REM MAVEN_SKIP_RC - flag to disable loading of mavenrc files
@REM ----------------------------------------------------------------------------

See that @REM M2_HOME - location of maven2's installed home dir

Anyway usage of this pattern is now deprecated with maven 3.5 as per the documentation.

Based on problems in using M2_HOME related to different Maven versions installed and to simplify things, the usage of M2_HOME has been removed and is not supported any more MNG-5823, MNG-5836, MNG-5607

So now the mvn.cmd look like,

@REM -----------------------------------------------------------------------------
@REM Apache Maven Startup Script
@REM
@REM Environment Variable Prerequisites
@REM
@REM   JAVA_HOME          Must point at your Java Development Kit installation.
@REM   MAVEN_BATCH_ECHO  (Optional) Set to 'on' to enable the echoing of the batch commands.
@REM   MAVEN_BATCH_PAUSE (Optional) set to 'on' to wait for a key stroke before ending.
@REM   MAVEN_OPTS        (Optional) Java runtime options used when Maven is executed.
@REM   MAVEN_SKIP_RC     (Optional) Flag to disable loading of mavenrc files.
@REM -----------------------------------------------------------------------------

So what you need is JAVA_HOME to be set correctly. As per the new installation guide (as of 12/29/2017), Just add the maven bin directory path to the PATH variable. It should do the trick.

ex : export PATH=/opt/apache-maven-3.5.2/bin:$PATH

it seems to be the java SimpleDateFormat : http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

here are some tests i did around 11:30pm on the 20th of May 2015

${__time(dd-mmm-yyyy HHmmss)} 20-032-2015 233224
${__time(d-MMM-yyyy hhmmss)}  20-May-2015 113224
${__time(dd-m-yyyy hhmmss)}   20-32-2015 113224
${__time(D-M-yyyy hhmmss)}    140-5-2015 113224
${__time(DD-MM-yyyy)}         140-05-2015

Catching Exception will catch a RuntimeException

I was also having the same problem. I tried the following and it's working for me now:
Please try the following steps:

Go to..

File > Settings > Appearance & Behavior > System Settings > HTTP Proxy [Under IDE Settings] Enable following option Auto-detect proxy settings

On Mac it's under:

Android Studio > Preferences > Appearance & Behaviour... etc

you can also use the test connection button and check with google.com to see if it works or not.

you can make two function one for Ascending and another for Descending the next two functions work after convert array to List

public List<Integer> sortDescending(List<Integer> arr){
    Comparator<Integer> c = Collections.reverseOrder();
    Collections.sort(arr,c);
    return arr;
  }

next function

public List<Integer> sortAscending(List<Integer> arr){   
    Collections.sort(arr);
    return arr;
  }

Since it is in the directory data/, You need to do:

file path is '../../data/file.json'

$.getJSON('../../data/file.json', function(data) {         
    alert(data);
});

Pure JS:

   var request = new XMLHttpRequest();
   request.open("GET", "../../data/file.json", false);
   request.send(null)
   var my_JSON_object = JSON.parse(request.responseText);
   alert (my_JSON_object.result[0]);
