They're the same thing. A URI is a generalization of a URL. Originally, URIs were planned to be divided into URLs (addresses) and URNs (names) but then there was little difference between a URL and URI and http URIs were used as namespaces even though they didn't actually locate any resources.

All valid characters that can be used in a URI (a URL is a type of URI) are defined in RFC 3986.

All other characters can be used in a URL provided that they are "URL Encoded" first. This involves changing the invalid character for specific "codes" (usually in the form of the percent symbol (%) followed by a hexadecimal number).

This link, HTML URL Encoding Reference, contains a list of the encodings for invalid characters.

When you do your #includes in main.c, put the #include reference to the file that contains the referenced function at the top of the include list. e.g. Say this is main.c and your referenced function is in "SSD1306_LCD.h"

#include "SSD1306_LCD.h"    
#include "system.h"        #include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <string.h>
#include <math.h>
#include <libpic30.h>       // http://microchip.wikidot.com/faq:74
#include <stdint.h>
#include <stdbool.h>
#include "GenericTypeDefs.h"  // This has the 'BYTE' type definition

The above will not generate the "implicit declaration of function" error, but below will-

#include "system.h"        
#include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <string.h>
#include <math.h>
#include <libpic30.h>       // http://microchip.wikidot.com/faq:74
#include <stdint.h>
#include <stdbool.h>
#include "GenericTypeDefs.h"     // This has the 'BYTE' type definition
#include "SSD1306_LCD.h"    

Exactly the same #include list, just different order.

Well, it did for me.

Yes you can (this is how I understand the original question). Here is how I did it. Just tie it into outside context. For example:

//javascript

my_function = null;

//jquery 
 $(function() { 

        function my_fun(){ 
               /.. some operations ../ 
        }  
        my_function = my_fun;
 }) 

 //just js 
 function js_fun () {  
       my_function(); //== call jquery function - just Reference is globally defined not function itself
}

I encountered this same problem when trying to access methods of the object, that was instantiated on DOM object ready only. Works. My example:

MyControl.prototype = {
   init:   function { 
        // init something
   }
   update: function () {
           // something useful, like updating the list items of control or etc.         
   }
}

MyCtrl = null;

// create jquery plug-in
$.fn.aControl = function () {
    var control = new MyControl(this);
    control.init();
    MyCtrl = control; // here is the trick
    return control;
}

now you can use something simple like:

function() = {
   MyCtrl.update(); // yes!
}

If this is just for debugging output, you can use the following to see all the types and values as well.

var_dump($obj);

If you want more control over the output you can use this:

foreach ($obj as $key => $value) {
    echo "$key => $value\n";
}

This piece of code may help..

#include <bits/stdc++.h>
using namespace std;    

class node{
public:
    int age;
    string name;
    node(int a, string b){
        age = a;
        name = b;
    }
};

bool operator<(const node& a, const node& b) {

    node temp1=a,temp2=b;
    if(a.age != b.age)
        return a.age > b.age;
    else{
        return temp1.name.append(temp2.name) > temp2.name.append(temp1.name);
    }
}

int main(){
    priority_queue<node> pq;
    node b(23,"prashantandsoon..");
    node a(22,"prashant");
    node c(22,"prashantonly");
    pq.push(b);
    pq.push(a);
    pq.push(c);

    int size = pq.size();
    for (int i = 0; i < size; ++i)
    {
        cout<<pq.top().age<<" "<<pq.top().name<<"\n";
        pq.pop();
    }
}

Output:

22 prashantonly
22 prashant
23 prashantandsoon..

I resolved this by adding @Transactional to the base/generic Hibernate DAO implementation class (the parent class which implements the saveOrUpdate() method inherited by the DAO I use in the main program), i.e. the @Transactional needs to be specified on the actual class which implements the method. My assumption was instead that if I declared @Transactional on the child class then it included all of the methods that were inherited by the child class. However it seems that the @Transactional annotation only applies to methods implemented within a class and not to methods inherited by a class.

Since I often come here and then wondering how to use the brackets, this answer might be useful for those like me.

EXEC sp_rename '[DB].[dbo].[Tablename].OldColumnName', 'NewColumnName', 'COLUMN'; 

• The OldColumnName must not be in []. It will not work.
• Don't put NewColumnName into [], it will result into [[NewColumnName]].

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

The accepted (and correct) answer says that "you can include this [Constants.h] file... in the pre-compiled header for the project."

As a novice, I had difficulty doing this without further explanation -- here's how: In your YourAppNameHere-Prefix.pch file (this is the default name for the precompiled header in Xcode), import your Constants.h inside the #ifdef __OBJC__ block.

#ifdef __OBJC__
  #import <UIKit/UIKit.h>
  #import <Foundation/Foundation.h>
  #import "Constants.h"
#endif

Also note that the Constants.h and Constants.m files should contain absolutely nothing else in them except what is described in the accepted answer. (No interface or implementation).

You can use this:

import java.util.Timer;

and for the delay itself, add:

 new Timer().schedule(
                    new TimerTask(){
                
                        @Override
                        public void run(){
                            
                        //if you need some code to run when the delay expires
                        }
                        
                    }, delay);

where the delay variable is in milliseconds; for example set delay to 5000 for a 5-second delay.

Consider

 var x = document.getElementById("age");

Here x is the element with id="age".

Now look at the following line

var age = document.getElementById("age").value;

this means you are getting the value of the element which has id="age"

You can use BigInteger:

From Integers:

byte[] array = BigInteger.valueOf(0xAABBCCDD).toByteArray();
System.out.println(Arrays.toString(array))
// --> {-86, -69, -52, -35 }

The returned array is of the size that is needed to represent the number, so it could be of size 1, to represent 1 for example. However, the size cannot be more than four bytes if an int is passed.

From Strings:

BigInteger v = new BigInteger("AABBCCDD", 16);
byte[] array = v.toByteArray();

However, you will need to watch out, if the first byte is higher 0x7F (as is in this case), where BigInteger would insert a 0x00 byte to the beginning of the array. This is needed to distinguish between positive and negative values.

Try (doc here, SO snippet not works so run this one)

document.cookie = "test=1"             // set
document.cookie = "test=1;max-age=0"   // unset

KeyPress is a higher level of abstraction than KeyDown (and KeyUp). KeyDown and KeyUp are hardware related: the actual action of a key on the keyboard. KeyPress is more "I received a character from the keyboard".

There are a problem with the selected -and right by the way- solution, is that if you want to add style that will apply to images like ( borders for example ) .

for example :

img {_x000D_
  color:#fff;_x000D_
  border: 1px solid black;_x000D_
  padding: 5px;_x000D_
  background-color: #ccc;_x000D_
}

<img src="http://badsrc.com/blah" alt="BLAH BLAH BLAH" /> <hr />_x000D_
<img src="https://cdn4.iconfinder.com/data/icons/miu-square-flat-social/60/stackoverflow-square-social-media-128.png" alt="BLAH BLAH BLAH" />

as you can see, all of images will apply the same style

there is another approach to easily work around such an issue, using onerror and injecting some special class to deal with the interrupted images :

.invalidImageSrc {_x000D_
  color:#fff;_x000D_
  border: 1px solid black;_x000D_
  padding: 5px;_x000D_
  background-color: #ccc;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>_x000D_
_x000D_
<img onerror="$(this).addClass('invalidImageSrc')" src="http://badsrc.com/blah" alt="BLAH BLAH BLAH" /> <hr />_x000D_
<img onerror="$(this).addClass('invalidImageSrc')" src="https://cdn4.iconfinder.com/data/icons/miu-square-flat-social/60/stackoverflow-square-social-media-128.png" alt="BLAH BLAH BLAH" />

Download Androidx86 from this This is an iso file, so you'd
need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux instead of Other.

After creating the virtual machine set the network adapter to 'Bridged'. · Start the VM and select 'Live CD VESA' at boot.

Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this.

Now you need open a command prompt and go to your android install folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.

Type adb connect IP_ADDRESS. There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.

In VirtualBox screen, go to Devices>USB devices. Select your dongle.

Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.

Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.

Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .

Here is a very good discussion about using regular expressions to validate email addresses; "Comparing E-mail Address Validating Regular Expressions"

Here is the current top expression, that is JavaScript compatible, for reference purposes:

/^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*@([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$/i

Use built-in Exception Handling Middleware

Step 1. In your startup, register your exception handling route:

// It should be one of your very first registrations
app.UseExceptionHandler("/error"); // Add this
app.UseEndpoints(endpoints => endpoints.MapControllers());

Step 2. Create controller that will handle all exceptions and produce error response:

[ApiExplorerSettings(IgnoreApi = true)]
public class ErrorsController : ControllerBase
{
    [Route("error")]
    public MyErrorResponse Error()
    {
        var context = HttpContext.Features.Get<IExceptionHandlerFeature>();
        var exception = context.Error; // Your exception
        var code = 500; // Internal Server Error by default

        if      (exception is MyNotFoundException) code = 404; // Not Found
        else if (exception is MyUnauthException)   code = 401; // Unauthorized
        else if (exception is MyException)         code = 400; // Bad Request

        Response.StatusCode = code; // You can use HttpStatusCode enum instead

        return new MyErrorResponse(exception); // Your error model
    }
}

A few important notes and observations:

• [ApiExplorerSettings(IgnoreApi = true)] is needed. Otherwise, it may break your Swashbuckle swagger
• Again, app.UseExceptionHandler("/error"); has to be one of the very top registrations in your Startup Configure(...) method. It's probably safe to place it at the top of the method.
• The path in app.UseExceptionHandler("/error") and in controller [Route("error")] should be the same, to allow the controller handle exceptions redirected from exception handler middleware.

Microsoft documentation for this subject is not that great but has some interesting ideas. I'll just leave the link here.

Response models and custom exceptions

Implement your own response model and exceptions. This example is just a good starting point. Every service would need to handle exceptions in its own way. But with this code, you have full flexibility and control over handling exceptions and returning a proper result to the caller.

An example of error response model (just to give you some ideas):

public class MyErrorResponse
{
    public string Type { get; set; }
    public string Message { get; set; }
    public string StackTrace { get; set; }

    public MyErrorResponse(Exception ex)
    {
        Type = ex.GetType().Name;
        Message = ex.Message;
        StackTrace = ex.ToString();
    }
}

For simpler services, you might want to implement http status code exception that would look like this:

public class HttpStatusException : Exception
{
    public HttpStatusCode Status { get; private set; }

    public HttpStatusException(HttpStatusCode status, string msg) : base(msg)
    {
        Status = status;
    }
}

This can be thrown like that:

throw new HttpStatusCodeException(HttpStatusCode.NotFound, "User not found");

Then your handling code could be simplified to:

if (exception is HttpStatusException httpException)
{
    code = (int) httpException.Status;
}

Why so un-obvious HttpContext.Features.Get<IExceptionHandlerFeature>()?

ASP.NET Core developers embraced the concept of middlewares where different aspects of functionality such as Auth, Mvc, Swagger etc. are separated and executed sequentially by processing the request and returning the response or passing the execution to the next middleware. With this architecture, MVC itself, for instance, would not be able to handle errors happening in Auth. So, they came up with exception handling middleware that catches all the exceptions happening in middlewares registered down in the pipeline, pushes exception data into HttpContext.Features, and re-runs the pipeline for specified route (/error), allowing any middleware to handle this exception, and the best way to handle it is by our Controllers to maintain proper content negotiation.

This is the quick and easy way to do it

<div>
    <span>Span 1</span>
    <span>Span 2</span>
    <span>Span 3</span>
</div>

css

div{
    width:100%;
}
span{
    display:inline-block;    
    width:33%;
    text-align:center;
}

Then adjust the width of the spans for the number you have.

Example: http://jsfiddle.net/jasongennaro/wvJxD/

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

This is for swift 2.3 Version. You can get the width of string.

var sizeOfString = CGSize()
if let font = UIFont(name: "Helvetica", size: 14.0)
    {
        let finalDate = "Your Text Here"
        let fontAttributes = [NSFontAttributeName: font] // it says name, but a UIFont works
        sizeOfString = (finalDate as NSString).sizeWithAttributes(fontAttributes)
    }

I could repro this by setting the name of input tag the same for two groups of input like below:

<body>
  <div>
      <div>
        <h3>Header1</h3>
      </div>
      <div>
          <input type="radio" name="gender" id="male_1" value="male"> Male<br>
          <input type="radio" name="gender" id="female_1" value="female" checked="checked"> Female<br>
          <input type="submit" value="Submit">
      </div>
  </div>


  <div>
      <div>
        <h3>Header2</h3>
      </div>
      <div>
          <input type="radio" name="gender" id="male_2" value="male"> Male<br>
          <input type="radio" name="gender" id="female_2" value="female" checked="checked"> Female<br>
          <input type="submit" value="Submit">
      </div>
  </div>
</body>

(To see this running, click here)

The following two solutions both fix the problem:

1. Use different names for the inputs in the second group
2. Use form tag instead of div tag for one of the groups (can't really figure out the real reason why this would solve the problem. Would love to hear some opinions on this!)

10 minutes ago i had the same problem of place label above input

then i got a small ugly resolution

<form>
    <h4><label for="male">Male</label></h4>
    <input type="radio" name="sex" id="male" value="male">
</form>

The disadvantage is that there is a big blank space between the label and input, of course you can adjust the css

First we need to set <serviceDebug includeExceptionDetailInFaults="True" /> in web.config:

<serviceBehaviors> 
 <behavior name=""> 
  <serviceMetadata httpGetEnabled="true" /> 
    **<serviceDebug includeExceptionDetailInFaults="true" />** 
 </behavior> 
</serviceBehaviors>

In addition to that at jquery level in error part you need to parse error response that contains exception like:

.error(function (response, q, t) { 
  var r = jQuery.parseJSON(response.responseText); 
}); 

Then using r.Message you can actully show exception text.

Check complete code: http://www.codegateway.com/2012/04/jquery-ajax-handle-exception-thrown-by.html

EDIT: A simple possibility to eliminate before getting into more complicated solutions: have you tried setting the character set to utf8 in the text editor in which you're reading the file? This could just be a case of somebody sending you a utf8 file that you're reading in an editor set to say cp1252.

Just taking the two examples, this is a case of utf8 being read through the lens of a single-byte encoding, likely one of iso-8859-1, iso-8859-15, or cp1252. If you can post examples of other problem characters, it should be possible to narrow that down more.

As visual inspection of the characters can be misleading, you'll also need to look at the underlying bytes: the § you see on screen might be either 0xa7 or 0xc2a7, and that will determine the kind of character set conversion you have to do.

Can you assume that all of your data has been distorted in exactly the same way - that it's come from the same source and gone through the same sequence of transformations, so that for example there isn't a single é in your text, it's always ç? If so, the problem can be solved with a sequence of character set conversions. If you can be more specific about the environment you're in and the database you're using, somebody here can probably tell you how to perform the appropriate conversion.

Otherwise, if the problem characters are only occurring in some places in your data, you'll have to take it instance by instance, based on assumptions along the lines of "no author intended to put ç in their text, so whenever you see it, replace by ç". The latter option is more risky, firstly because those assumptions about the intentions of the authors might be wrong, secondly because you'll have to spot every problem character yourself, which might be impossible if there's too much text to visually inspect or if it's written in a language or writing system that's foreign to you.

ConfigParser Basic example

The file can be loaded and used like this:

#!/usr/bin/env python

import ConfigParser
import io

# Load the configuration file
with open("config.yml") as f:
    sample_config = f.read()
config = ConfigParser.RawConfigParser(allow_no_value=True)
config.readfp(io.BytesIO(sample_config))

# List all contents
print("List all contents")
for section in config.sections():
    print("Section: %s" % section)
    for options in config.options(section):
        print("x %s:::%s:::%s" % (options,
                                  config.get(section, options),
                                  str(type(options))))

# Print some contents
print("\nPrint some contents")
print(config.get('other', 'use_anonymous'))  # Just get the value
print(config.getboolean('other', 'use_anonymous'))  # You know the datatype?

which outputs

List all contents
Section: mysql
x host:::localhost:::<type 'str'>
x user:::root:::<type 'str'>
x passwd:::my secret password:::<type 'str'>
x db:::write-math:::<type 'str'>
Section: other
x preprocessing_queue:::["preprocessing.scale_and_center",
"preprocessing.dot_reduction",
"preprocessing.connect_lines"]:::<type 'str'>
x use_anonymous:::yes:::<type 'str'>

Print some contents
yes
True

As you can see, you can use a standard data format that is easy to read and write. Methods like getboolean and getint allow you to get the datatype instead of a simple string.

Writing configuration

import os
configfile_name = "config.yaml"

# Check if there is already a configurtion file
if not os.path.isfile(configfile_name):
    # Create the configuration file as it doesn't exist yet
    cfgfile = open(configfile_name, 'w')

    # Add content to the file
    Config = ConfigParser.ConfigParser()
    Config.add_section('mysql')
    Config.set('mysql', 'host', 'localhost')
    Config.set('mysql', 'user', 'root')
    Config.set('mysql', 'passwd', 'my secret password')
    Config.set('mysql', 'db', 'write-math')
    Config.add_section('other')
    Config.set('other',
               'preprocessing_queue',
               ['preprocessing.scale_and_center',
                'preprocessing.dot_reduction',
                'preprocessing.connect_lines'])
    Config.set('other', 'use_anonymous', True)
    Config.write(cfgfile)
    cfgfile.close()

results in

[mysql]
host = localhost
user = root
passwd = my secret password
db = write-math

[other]
preprocessing_queue = ['preprocessing.scale_and_center', 'preprocessing.dot_reduction', 'preprocessing.connect_lines']
use_anonymous = True

XML Basic example

Seems not to be used at all for configuration files by the Python community. However, parsing / writing XML is easy and there are plenty of possibilities to do so with Python. One is BeautifulSoup:

from BeautifulSoup import BeautifulSoup

with open("config.xml") as f:
    content = f.read()

y = BeautifulSoup(content)
print(y.mysql.host.contents[0])
for tag in y.other.preprocessing_queue:
    print(tag)

where the config.xml might look like this

<config>
    <mysql>
        <host>localhost</host>
        <user>root</user>
        <passwd>my secret password</passwd>
        <db>write-math</db>
    </mysql>
    <other>
        <preprocessing_queue>
            <li>preprocessing.scale_and_center</li>
            <li>preprocessing.dot_reduction</li>
            <li>preprocessing.connect_lines</li>
        </preprocessing_queue>
        <use_anonymous value="true" />
    </other>
</config>

Dapper supports this directly. For example...

string sql = "SELECT * FROM SomeTable WHERE id IN @ids"
var results = conn.Query(sql, new { ids = new[] { 1, 2, 3, 4, 5 }});

Just add this line

sFileName = "C:\someotherfilelocation"

right before this line

Open sFileName For Output As iFileNum

The idea is to open and write to a different file than the one you read earlier (C:\filelocation).

If you want to get fancy and show a real "Save As" dialog box, you could do this instead:

sFileName = Application.GetSaveAsFilename()

Update 10/11/2020 to reflect the latest brew changes.

Brew already provide a command to uninstall itself (this will remove everything you installed with Homebrew):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

If you failed to run this command due to permission (like run as second user), run again with sudo

Then you can install again:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

It works for me just run following command

git config --global http.sslVerify false

it will open a git credentials window give your credentials . for first time only it ask

         WHEN ISNUMERIC(RTRIM(userID) + '.0e0') = 1
              AND LEN(userID) <= 11
           THEN CAST(userID AS INT)
       END
FROM   audit 

Both return NULL if the value cannot be cast.

In the specific case that you have in your question with known bad values I would use the following however.

CAST(REPLACE(userID COLLATE Latin1_General_Bin, CHAR(0),'') AS INT)

Trying to replace the null character is often problematic except if using a binary collation.

Observe that you'd have the same problem if you used limited-precision decimal arithmetic, and wanted to deal with 1/3: 0.333333333 * 3 is 0.999999999, not 1.00000000.

Unfortunately, 5.6, 5.8 and 11.4 just aren't round numbers in binary, because they involve fifths. So the float representation of them isn't exact, just as 0.3333 isn't exactly 1/3.

If all the numbers you use are non-recurring decimals, and you want exact results, use BigDecimal. Or as others have said, if your values are like money in the sense that they're all a multiple of 0.01, or 0.001, or something, then multiply everything by a fixed power of 10 and use int or long (addition and subtraction are trivial: watch out for multiplication).

However, if you are happy with binary for the calculation, but you just want to print things out in a slightly friendlier format, try java.util.Formatter or String.format. In the format string specify a precision less than the full precision of a double. To 10 significant figures, say, 11.399999999999 is 11.4, so the result will be almost as accurate and more human-readable in cases where the binary result is very close to a value requiring only a few decimal places.

The precision to specify depends a bit on how much maths you've done with your numbers - in general the more you do, the more error will accumulate, but some algorithms accumulate it much faster than others (they're called "unstable" as opposed to "stable" with respect to rounding errors). If all you're doing is adding a few values, then I'd guess that dropping just one decimal place of precision will sort things out. Experiment.

Trevor Sullivan has a write-up on how to add a command called Copy-ItemWithProgress to PowerShell on Robocopy.

Why is MichalBE getting downvoted? He's right - using jQuery (or any library) just to fire a function on page load is overkill, potentially costing people money on mobile connections and slowing down the user experience. If the original poster doesn't want to use onload in the body tag (and he's quite right not to), add this after the draw() function:

if (draw) window.onload = draw;

Or this, by Simon Willison, if you want more than one function to be executed:

function addLoadEvent(func) {
    var oldonload = window.onload;
    if (typeof window.onload != 'function') {
        window.onload = func;
    } else {
        window.onload = function() {
            if (oldonload) {
                oldonload();
            }
            func();
        }
    }
}

You have to update your app.config file manually

// Load the app.config file
XmlDocument xml = new XmlDocument();
xml.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);

// Do whatever you need, like modifying the appSettings section

// Save the new setting
xml.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);

And then tell your application to reload any section you modified

ConfigurationManager.RefreshSection("appSettings");

If you have Windows Vista or above please run this from a command prompt as Administrator:

sc delete [your service name as shown in service.msc e.g moneytransfer]

For example: sc delete moneytransfer

These steps have been tested on Windows XP, Windows 7, Windows Vista, Windows Server 2003, and Windows Server 2008.

GitLens has a nice Git history browser. Install GitLens from the extensions marketplace, and then run "Show GitLens Explorer" from the command palette.

If you are looking for a quick and manual process with UI. I always use Mozilla Firefox to convert from PFX to P12. First import the certificate into the Firefox browser (Options > Privacy & Security > View Certificates... > Import...). Once installed, perform the export to create the P12 file by choosing the certificate name from the Certificate Manager and then click Backup... and enter the file name and then enter the password.

You can't run the request from a browser, it will timeout waiting for the server running the CURL request to respond. The browser is probably timing out in 1-2 minutes, the default network timeout.

You need to run it from the command line/terminal.

I think you should use something like this and it is called Upcasting:

public int multiplyBy2(int x) throws ArithmeticException {
    long result = 2 * (long) x;    
    if (result > Integer.MAX_VALUE || result < Integer.MIN_VALUE){
        throw new ArithmeticException("Integer overflow");
    }
    return (int) result;
}

You can read further here: Detect or prevent integer overflow

Actually its pretty easy to make integration between Csharp (VS) and Python with IronPython. It's not that much complex... As Chris Dunaway already said in answer section I started to build this inegration for my own project. N its pretty simple. Just follow these steps N you will get your results.

step 1 : Open VS and create new empty ConsoleApp project.

step 2 : Go to tools --> NuGet Package Manager --> Package Manager Console.

step 3 : After this open this link in your browser and copy the NuGet Command. Link: https://www.nuget.org/packages/IronPython/2.7.9

step 4 : After opening the above link copy the PM>Install-Package IronPython -Version 2.7.9 command and paste it in NuGet Console in VS. It will install the supportive packages.

step 5 : This is my code that I have used to run a .py file stored in my Python.exe directory.

using IronPython.Hosting;//for DLHE
using Microsoft.Scripting.Hosting;//provides scripting abilities comparable to batch files
using System;
using System.Diagnostics;
using System.IO;
using System.Net;
using System.Net.Sockets;
class Hi
{
private static void Main(string []args)
{
Process process = new Process(); //to make a process call
ScriptEngine engine = Python.CreateEngine(); //For Engine to initiate the script
engine.ExecuteFile(@"C:\Users\daulmalik\AppData\Local\Programs\Python\Python37\p1.py");//Path of my .py file that I would like to see running in console after running my .cs file from VS.//process.StandardInput.Flush();
process.StandardInput.Close();//to close
process.WaitForExit();//to hold the process i.e. cmd screen as output
}
} 

step 6 : save and execute the code

in Core Php to hide warning message set error_reporting(0) at top of common include file or individual file.

In Wordpress hide Warnings and Notices add following code in wp-config.php file

ini_set('log_errors','On');
ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Instead of JSONObject , you can use ObjectMapper to convert java object to json string

ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);

You can make the app dismiss the keyboard using the following function

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    self.view.endEditing(true)
    return false
}

Here is a full example to better illustrate that:

//
//  ViewController.swift
//
//

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet var myTextField : UITextField

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        self.myTextField.delegate = self
    }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        self.view.endEditing(true)
        return false
    }
}

I agree with @kent that this is well suited for grep -o. If you need to extract a group within a pattern, you can do it with a 2nd grep.

# To extract \1 from /xx([0-9]+)yy/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'xx[0-9]+yy' | grep -Eo '[0-9]+'
123
4

# To extract \1 from /a([0-9]+)b/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'a[0-9]+b' | grep -Eo '[0-9]+'
678

I generally cringe when I see 2 calls to grep/sed/awk piped together, but it's not always wrong. While we should exercise our skills of doing things efficiently, "A foolish consistency is the hobgoblin of little minds", and "Real artists ship".

As it is, both dimensions of your vector are 0.

Instead, initialize the vector as this:

vector<vector<int> > matrix(RR);
for ( int i = 0 ; i < RR ; i++ )
   matrix[i].resize(CC);

This will give you a matrix of dimensions RR * CC with all elements set to 0.

I have a rotating image using the same thing as you:

    margin:0 auto;
    margin-left:-195px;
    z-index:0;

    -webkit-transition-duration: 0.8s;
    -moz-transition-duration: 0.8s;
    -o-transition-duration: 0.8s;
    transition-duration: 0.8s;

    -webkit-transition-property: -webkit-transform;
    -moz-transition-property: -moz-transform;
    -o-transition-property: -o-transform;
     transition-property: transform;

     overflow:hidden;
}

.knoop1:hover img{
    -webkit-transform:rotate(360deg);
    -moz-transform:rotate(360deg); 
    -o-transform:rotate(360deg);
}

TL;DR

Error #1064 means that MySQL can't understand your command. To fix it:

• Read the error message. It tells you exactly where in your command MySQL got confused.

• Examine your command. If you use a programming language to create your command, use echo, console.log(), or its equivalent to show the entire command so you can see it.

• Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.

• Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).

1. Aaaagh!! What does #1064 mean?

   Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.

   As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.

   • What is this "syntax" of which you speak? Is it witchcraft?

     Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.

     For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):

     This sentence contains syntax error a.

   • What does that have to do with MySQL?

     Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.

     It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.

2. How do I fix it?

   Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…

   • Read the message!

     MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:

     UPDATE my_table WHERE id=101 SET name='foo'
     

     That command yields the following error message:

     ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1

     MySQL is telling us that everything seemed fine up to the word WHERE, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE at that point.

     Messages that say ...near '' at line... simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.

   • Examine the actual text of your command!

     Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:

     $result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
     

     If you write this this in two lines

     $query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
     $result = $mysqli->query($query);
     

     then you can add echo $query; or var_dump($query) to see that the query actually says

     UPDATE userSET name='foo' WHERE id=101
     

     Often you'll see your error immediately and be able to fix it.

   • Obey orders!

     MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.

     I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE command. The very first thing on the page is the command's grammar (this is true for every command):

     UPDATE [LOW_PRIORITY] [IGNORE] table_reference
         SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
         [WHERE where_condition]
         [ORDER BY ...]
         [LIMIT row_count]
     

     The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [ and ] are optional; vertical bars | indicate alternatives; and ellipses ... denote either an omission for brevity, or that the preceding clause may be repeated.

     We already know that the parser believed everything in our command was okay prior to the WHERE keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference must be followed by the SET keyword: whereas in our command it was actually followed by the WHERE keyword. This explains why the parser reports that a problem was encountered at that point.

   A note of reservation

   Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.

   I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:

   UPDATE my_table SET where='foo'
   

   Again, the parser does not expect to encounter WHERE at this point and so will raise a similar syntax error—but you hadn't intended for that where to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:

   If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.

   [ deletia ]

   The identifier quote character is the backtick (“`”):

   mysql> SELECT * FROM `select` WHERE `select`.id > 100;

   If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:

   mysql> CREATE TABLE "test" (col INT);
   ERROR 1064: You have an error in your SQL syntax...
   mysql> SET sql_mode='ANSI_QUOTES';
   mysql> CREATE TABLE "test" (col INT);
   Query OK, 0 rows affected (0.00 sec)

To improve upon the answer given by derobert,

You can determine what your OS connection limit is by catting nf_conntrack_max.

For example: cat /proc/sys/net/netfilter/nf_conntrack_max

You can use the following script to count the number of tcp connections to a given range of tcp ports. By default 1-65535.

This will confirm whether or not you are maxing out your OS connection limit.

Here's the script.

#!/bin/bash
OS=$(uname)

case "$OS" in
    'SunOS')
            AWK=/usr/bin/nawk
            ;;
    'Linux')
            AWK=/bin/awk
            ;;
    'AIX')
            AWK=/usr/bin/awk
            ;;
esac

netstat -an | $AWK -v start=1 -v end=65535 ' $NF ~ /TIME_WAIT|ESTABLISHED/ && $4 !~ /127\.0\.0\.1/ {
    if ($1 ~ /\./)
            {sip=$1}
    else {sip=$4}

    if ( sip ~ /:/ )
            {d=2}
    else {d=5}

    split( sip, a, /:|\./ )

    if ( a[d] >= start && a[d] <= end ) {
            ++connections;
            }
    }
    END {print connections}'

try this it is quite simple and give you cant make changes to your .css file this should work

<p align="center">
<button type="button" style="background-color:yellow;margin-left:auto;margin-right:auto;display:block;margin-top:22%;margin-bottom:0%"> mybuttonname</button>
</p>

If your using the RichFaces library you can also use the tag rich:spacer which will add an "invisible" image with a given length and height. Usually much easier and prettier than to add tons of nbsp;.

Where you want your space to show you simply add:

<rich:spacer height="1" width="2" />

Just put ${yourpathtofile/folder}

PowerShell does not count spaces; to tell PowerShell to consider the whole path including spaces, add your path in between ${ & }.

    for (int i = 0; i < 256; i++) {
        System.out.println(i + " -> " + (char) i);
    }

    char lowercase = 'f';
    int offset = (int) 'a' - (int) 'A';
    char uppercase = (char) ((int) lowercase - offset);
    System.out.println("The uppercase letter is " + uppercase);

    String numberString = JOptionPane.showInputDialog(null,
            "Enter an ASCII code:",
            "ASCII conversion", JOptionPane.QUESTION_MESSAGE);

    int code = (int) numberString.charAt(0);
    System.out.println("The character for ASCII code "
            + code + " is " + (char) code);

Just single if conditions

<select name="category_type[]" id="category_type" class="select2 m-b-10 select2-multiple" style="width: 100%" multiple="multiple" data-placeholder="Choose" tooltip="Select Category Type">
 @foreach ($categoryTypes as $categoryType)
  <option value="{{ $categoryType->id }}"
    **@if(in_array($categoryType->id,
     request()->get('category_type')??[]))selected="selected"
    @endif**>
     {{ ucfirst($categoryType->title) }}</option>
     @endforeach
 </select>

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

You don't need to encode data that is already encoded. When you try to do that, Python will first try to decode it to unicode before it can encode it back to UTF-8. That is what is failing here:

>>> data = u'\u00c3'            # Unicode data
>>> data = data.encode('utf8')  # encoded to UTF-8
>>> data
'\xc3\x83'
>>> data.encode('utf8')         # Try to *re*-encode it
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Just write your data directly to the file, there is no need to encode already-encoded data.

If you instead build up unicode values instead, you would indeed have to encode those to be writable to a file. You'd want to use codecs.open() instead, which returns a file object that will encode unicode values to UTF-8 for you.

You also really don't want to write out the UTF-8 BOM, unless you have to support Microsoft tools that cannot read UTF-8 otherwise (such as MS Notepad).

For your MySQL insert problem, you need to do two things:

• Add charset='utf8' to your MySQLdb.connect() call.

• Use unicode objects, not str objects when querying or inserting, but use sql parameters so the MySQL connector can do the right thing for you:

  artiste = artiste.decode('utf8')  # it is already UTF8, decode to unicode
  
  c.execute('SELECT COUNT(id) AS nbr FROM artistes WHERE nom=%s', (artiste,))
  
  # ...
  
  c.execute('INSERT INTO artistes(nom,status,path) VALUES(%s, 99, %s)', (artiste, artiste + u'/'))
  

It may actually work better if you used codecs.open() to decode the contents automatically instead:

import codecs

sql = mdb.connect('localhost','admin','ugo&(-@F','music_vibration', charset='utf8')

with codecs.open('config/index/'+index, 'r', 'utf8') as findex:
    for line in findex:
        if u'#artiste' not in line:
            continue

        artiste=line.split(u'[:::]')[1].strip()

    cursor = sql.cursor()
    cursor.execute('SELECT COUNT(id) AS nbr FROM artistes WHERE nom=%s', (artiste,))
    if not cursor.fetchone()[0]:
        cursor = sql.cursor()
        cursor.execute('INSERT INTO artistes(nom,status,path) VALUES(%s, 99, %s)', (artiste, artiste + u'/'))
        artists_inserted += 1

You may want to brush up on Unicode and UTF-8 and encodings. I can recommend the following articles:

• The Python Unicode HOWTO

• Pragmatic Unicode by Ned Batchelder

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

I think something like:

function ReplaceContentInContainer(klass,content) {
var elems = document.getElementsByTagName('*');
for (i in elems){
    if(elems[i].getAttribute('class') == klass || elems[i].getAttribute('className') == klass){
        elems[i].innerHTML = content;
    }
}
}

would work

It is even funnier when you are doing it with inputs, because they should be bound. If you are interested in how to do it in Vue2 with options to insert and delete, please see an example:

Wrap your $adr in urlencode(). I was having this problem and this solved it for me.

The fastest and easiest way is to use .as_matrix(). One short line:

df.iloc[:,[1,2,3]].as_matrix()

Gives:

array([[3, 2, 0.816497],
   [0, 'NaN', 'NaN'],
   [2, 51, 50.0]], dtype=object)

By using indices of the columns, you can use this code for any dataframe with different column names.

Here are the steps for your example:

import pandas as pd
columns = ['viz', 'a1_count', 'a1_mean', 'a1_std']
index = [0,1,2]
vals = {'viz': ['n','n','n'], 'a1_count': [3,0,2], 'a1_mean': [2,'NaN', 51], 'a1_std': [0.816497, 'NaN', 50.000000]}
df = pd.DataFrame(vals, columns=columns, index=index)

Gives:

   viz  a1_count a1_mean    a1_std
0   n         3       2  0.816497
1   n         0     NaN       NaN
2   n         2      51        50

Then:

x1 = df.iloc[:,[1,2,3]].as_matrix()

Gives:

array([[3, 2, 0.816497],
   [0, 'NaN', 'NaN'],
   [2, 51, 50.0]], dtype=object)

Where x1 is numpy.ndarray.

var1="\t\t Test String trimming   "
echo $var1
Var2=$(echo "${var1}" | sed 's/^[[:space:]]*//;s/[[:space:]]*$//')
echo $Var2

try to add this section in your web.config file on web server, sometimes it happens with php pages:

<httpProtocol>
    <customHeaders>
        <clear />
        <add name="X-UA-Compatible" value="IE=edge" />
    </customHeaders>
</httpProtocol>

Simple solution:

double totalCost = 123.45678;
totalCost = Convert.ToDouble(String.Format("{0:0.00}", totalCost));

//output: 123.45

Simply you can do like this:

var formData = new FormData();
formData.append('array[key1]', this.array.key1);
formData.append('array[key2]', this.array.key2);

CGFloat width = [[UIScreen mainScreen] bounds].size.width; CGFloat height = [[UIScreen mainScreen]bounds ].size.height;

Escape with a double backslash

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat.

y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab:    , newline: 
## , unicode point: €

Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1

To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.

grepl("\\[", "a[b")
## [1] TRUE

To match backslashes, you need to double escape, resulting in four backslashes.

grepl("\\\\", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

The rebus package contains constants for each of the special characters to save you mistyping slashes.

library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"

For more examples see:

?SpecialCharacters

Your problem can be solved this way:

library(rebus)
grepl(OPEN_BRACKET, "a[b")

Form a character class

You can also wrap the special characters in square brackets to form a character class.

grepl("[?]", "a?b")
## [1] TRUE

Two of the special characters have special meaning inside character classes: \ and ^.

Backslash still needs to be escaped even if it is inside a character class.

grepl("[\\\\]", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

Caret only needs to be escaped if it is directly after the opening square bracket.

grepl("[ ^]", "a^b")  # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b") 
## [1] TRUE

rebus also lets you form a character class.

char_class("?")
## <regex> [?]

Use a pre-existing character class

If you want to match all punctuation, you can use the [:punct:] character class.

grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE

stringi maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

You can also use the cross-platform syntax for accessing a UGC.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

Use \Q \E escapes

Placing characters between \\Q and \\E makes the regular expression engine treat them literally rather than as regular expressions.

grepl("\\Q.\\E", "a.b")
## [1] TRUE

rebus lets you write literal blocks of regular expressions.

literal(".")
## <regex> \Q.\E

Don't use regular expressions

Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:

grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")

Simple way to implement this thing following this method

1st initial the EditText Field

  EditText editText = findViewById(R.id.editTextField);

When you done initialization. Now time to keep the imputed value in a variable

  final String userInput = editText.getText().toString();

Now Time to check the condition whether user fulfilled or not

  if (userInput.isEmpty()){
           editText.setError("This field need to fill up");
       
        }else{
         //Do what you want to do
      }

Here is an example how I did with my project

  private void sendMail() {
       final String userMessage = etMessage.getText().toString();
          if (userMessage.isEmpty()) {

            etMessage.setError("Write to us");

    }else{
       Toast.makeText(this, "You write to us"+etMessage, Toast.LENGTH_SHORT).show();
      }
   }

Hope it will help you.

Here is a generic example of using a weak reference and static handler class to resolve the problem (as recommended in the Lint documentation):

public class MyClass{

  //static inner class doesn't hold an implicit reference to the outer class
  private static class MyHandler extends Handler {
    //Using a weak reference means you won't prevent garbage collection
    private final WeakReference<MyClass> myClassWeakReference; 

    public MyHandler(MyClass myClassInstance) {
      myClassWeakReference = new WeakReference<MyClass>(myClassInstance);
    }

    @Override
    public void handleMessage(Message msg) {
      MyClass myClass = myClassWeakReference.get();
      if (myClass != null) {
        ...do work here...
      }
    }
  }

  /**
   * An example getter to provide it to some external class
   * or just use 'new MyHandler(this)' if you are using it internally.
   * If you only use it internally you might even want it as final member:
   * private final MyHandler mHandler = new MyHandler(this);
   */
  public Handler getHandler() {
    return new MyHandler(this);
  }
}

As of 15/06/2019

what I did is include all four possibilities to open url.

i.e, with http / https and 2 with www in prefix and 2 without www

and by using this my app launches automatically now without asking me to choose a browser and other option.

<intent-filter android:autoVerify="true">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />

    <data android:scheme="https" android:host="example.in" />
    <data android:scheme="https" android:host="www.example.in" />
    <data android:scheme="http" android:host="example.in" />
    <data android:scheme="http" android:host="www.example.in" />

</intent-filter>

Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error() and curl_errno() will contain further information in case of failure:

try {
    $ch = curl_init();

    // Check if initialization had gone wrong*    
    if ($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt(/* ... */);

    $content = curl_exec($ch);

    // Check the return value of curl_exec(), too
    if ($content === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }

    /* Process $content here */

    // Close curl handle
    curl_close($ch);
} catch(Exception $e) {

    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);

}

^* The curl_init() manual states:

Returns a cURL handle on success, FALSE on errors.

I've observed the function to return FALSE when you're using its $url parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

Did you add the .a library to the xcode projet ? (project -> build phases -> Link binary with libraries -> click on the '+' -> click 'add other' -> choose your library)

And maybe the library is not compatible with the simulator, did you try to compile for iDevice (not simulator) ?

(I've already fight with the second problem, I got a library that was not working with the simulator but with a real device it compiles...)

Given the array supplied below:

const array = [ 'a', 'b', 'b', 'c', 'c', 'c' ];

You can use this simple one-liner to generate a hash map which links a key to the number of times it appears in the array:

const hash = Object.fromEntries([ ...array.reduce((map, key) => map.set(key, (map.get(key) || 0) + 1), new Map()) ]);
// { a: 1, b: 2, c: 3 }

Expanded & Explained:

// first, we use reduce to generate a map with values and the amount of times they appear
const map = array.reduce((map, key) => map.set(key, (map.get(key) || 0) + 1), new Map())

// next, we spread this map into an array
const table = [ ...map ];

// finally, we use Object.fromEntries to generate an object based on this entry table
const result = Object.fromEntries(table);

Remove any capital letters or other not allowed symbols in resource file name.

Example: activity_parkingList --> activity_parking_list

You can use element.scrollTop and element.scrollLeft to get the vertical and horizontal offset, respectively, that has been scrolled. element can be document.body if you care about the whole page. You can compare it to element.offsetHeight and element.offsetWidth (again, element may be the body) if you need percentages.

For MSSQL Server 2012

CREATE TABLE usrgroup(
  usr_id int FOREIGN KEY REFERENCES users(id),
  grp_id int FOREIGN KEY REFERENCES groups(id),

  PRIMARY KEY (usr_id, grp_id)
)

UPDATE

I should add !

If you want to add foreign / primary keys altering, firstly you should create the keys with constraints or you can not make changes. Like this below:

CREATE TABLE usrgroup(
  usr_id int,
  grp_id int,

  CONSTRAINT FK_usrgroup_usrid FOREIGN KEY (usr_id) REFERENCES users(id),
  CONSTRAINT FK_usrgroup_groupid FOREIGN KEY (grp_id) REFERENCES groups(id),

  CONSTRAINT PK_usrgroup PRIMARY KEY (usr_id,grp_id)
)

Actually last way is healthier and serial. You can look the FK/PK Constraint names (dbo.dbname > Keys > ..) but if you do not use a constraint, MSSQL auto-creates random FK/PK names. You will need to look at every change (alter table) you need.

I recommend that you set a standard for yourself; the constraint should be defined according to the your standard. You will not have to memorize and you will not have to think too long. In short, you work faster.

You can't get any faster if you want to use an existing API to read the lines. But reading larger chunks and manually find each new line in the read buffer would probably be faster.

Cross browser testing java scripts

public class MultipleBrowser {

    public WebDriver driver= null;
    String browser="mozilla";
    String url="https://www.omnicard.com";

    @BeforeMethod
    public void LaunchBrowser() {

        if(browser.equalsIgnoreCase("mozilla"))
            driver= new FirefoxDriver();
        else if(browser.equalsIgnoreCase("safari"))
            driver= new SafariDriver();
        else if(browser.equalsIgnoreCase("chrome"))
            //System.setProperty("webdriver.chrome.driver","/Users/mhossain/Desktop/chromedriver");
            driver= new ChromeDriver(); 
        driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
        driver.navigate().to(url);
    }

}

but when you want to run firefox you need to chrome path disable, otherwise browser will launch but application may not.(try both way) .

If you are going to manage your memory manually, you have two cases:

1. I created the object (perhaps indirectly, by calling a function that allocates a new object), I use it (or a function I call uses it), then I free it.
2. Somebody gave me the reference, so I should not free it.

If you need to break any of these rules, please document it.

It is all about pointer ownership.

you should do those steps:

1. add CoreLocation.framework to BuildPhases -> Link Binary With Libraries (no longer necessary as of XCode 7.2.1)
2. import CoreLocation to your class - most likely ViewController.swift
3. add CLLocationManagerDelegate to your class declaration
4. add NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription to plist

5. init location manager:

   locationManager = CLLocationManager()
   locationManager.delegate = self;
   locationManager.desiredAccuracy = kCLLocationAccuracyBest
   locationManager.requestAlwaysAuthorization()
   locationManager.startUpdatingLocation()
   

6. get User Location By:

   func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
       let locValue:CLLocationCoordinate2D = manager.location!.coordinate
       print("locations = \(locValue.latitude) \(locValue.longitude)")
   }
   

You'll need to add this to your server configuration:

AddType application/x-httpd-php .php

That is assuming you have installed PHP properly, which may not be the case since it doesn't work where it normally would immediately after installing.

It is entirely possible that you'll also have to add the php .so/.dll file to your Apache configuration using a LoadModule directive (usually in httpd.conf).

First check the Visual studio version of the developer PC which can publish the solution(project). as shown is for VS 2013

 /p:VisualStudioVersion=12.0

add the above command line to specify what kind of a visual studio version should build the project. As previous answers, this might happen when we are trying to publish only one project, not the whole solution.

So the complete code would be something like this

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe" "C:\Program Files (x86)\Jenkins\workspace\Jenkinssecondsample\MVCSampleJenkins\MVCSampleJenkins.csproj" /T:Build;Package /p:Configuration=DEBUG /p:OutputPath="obj\DEBUG" /p:DeployIisAppPath="Default Web Site/jenkinsdemoapp" /p:VisualStudioVersion=12.0

If you know that certain characters are not used, you can translate "\t" into something else. cat my_file | tr "\t" "," | sed "s/(.*)/,\1/"

The answer is in the current spec:

The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading.

Examples of sections would be chapters, the various tabbed pages in a tabbed dialog box, or the numbered sections of a thesis. A Web site's home page could be split into sections for an introduction, news items, and contact information.

Authors are encouraged to use the article element instead of the section element when it would make sense to syndicate the contents of the element.

The section element is not a generic container element. When an element is needed for styling purposes or as a convenience for scripting, authors are encouraged to use the div element instead. A general rule is that the section element is appropriate only if the element's contents would be listed explicitly in the document's outline.

Reference:

• http://www.w3.org/TR/html5/sections.html#the-section-element
• http://www.whatwg.org/specs/web-apps/current-work/multipage/sections.html#the-section-element

Also see:

• http://html5doctor.com/the-section-element/
• http://www.impressivewebs.com/html5-section/

It looks like there's been a lot of confusion about this element's purpose, but the one thing that's agreed upon is that it is not a generic wrapper, like <div> is. It should be used for semantic purposes, and not a CSS or JavaScript hook (although it certainly can be styled or "scripted").

A better example, from my understanding, might look something like this:

<div id="content">
  <article>
     <h2>How to use the section tag</h2>
     <section id="disclaimer">
         <h3>Disclaimer</h3>
         <p>Don't take my word for it...</p>
     </section>
     <section id="examples">
       <h3>Examples</h3>
       <p>But here's how I would do it...</p>
     </section>
     <section id="closing_notes">
       <h3>Closing Notes</h3>
       <p>Well that was fun. I wonder if the spec will change next week?</p>
     </section>
  </article>
</div>

Note that <div>, being completely non-semantic, can be used anywhere in the document that the HTML spec allows it, but is not necessary.

create shake.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromXDelta="0" 
        android:toXDelta="10" 
            android:duration="1000" 
                android:interpolator="@anim/cycle" />

and cycle.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:cycles="4" />

now add animation on your code

Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);

If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value

string(byteslice) will convert byte slice to string, just know that it's not only simply type conversion, but also memory copy.

Here is a sample code with explanation.

 //Create a response instance
 $response = new Illuminate\Http\Response('Hello World');

 //Call the withCookie() method with the response method
 $response->withCookie(cookie('name', 'value', $minutes));

 //return the response
 return $response;

Cookie can be set forever by using the forever method as shown in the below code.

$response->withCookie(cookie()->forever('name', 'value'));

Retrieving a Cookie

//’name’ is the name of the cookie to retrieve the value of
$value = $request->cookie('name');

A lesser perplexing way to look at it would be:

string = 'happy'
print(string)

'happy'

string_reversed = string[-1::-1]
print(string_reversed)

'yppah'

In English [-1::-1] reads as:

"Starting at -1, go all the way, taking steps of -1"

Excluding the following files solved the problem.

META-INF/*.SF

META-INF/*.DSA

META-INF/*.RSA

Added the following code in build.gradle

jar {
    from {
        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
    {
        exclude "META-INF/*.SF"
        exclude "META-INF/*.DSA"
        exclude "META-INF/*.RSA"
    }
    manifest {
        attributes(
                'Main-Class': 'mainclass'
        )
    }
}

OK I have been struggling with cloning & renaming projects in Android Studio, but finally I achieved it. Here are the steps to follow:

1. Copy the project folder, rename it & open it with Android Studio
2. Rename module directory from explorer
3. Rename projectName.iml and content
4. Rename idea/.name content
5. In your Project pane, click on the little gear icon -> uncheck "Compact Empty Middle Package"
6. Refactor src directories for new package name (rename package, "not rename directory")
7. In build.gradle rename application id
8. settings.gradle rename module

That's it...

Yes, here is the process:

# Navigate to a directory and initiate a local repository
git init        

# Add remote repository to be tracked for changes:   
git remote add origin https://github.com/username/repository_name.git

# Track all changes made on above remote repository
# This will show files on remote repository not available on local repository
git fetch

# Add file present in staging area for checkout
git check origin/master -m /path/to/file
# NOTE: /path/to/file is a relative path from repository_name
git add /path/to/file

# Verify track of file(s) being committed to local repository
git status

# Commit to local repository
git commit -m "commit message"

# You may perform a final check of the staging area again with git status

Just adding to this as in case someone out there is suffering from never Reading The F Manual like me
I followed all the suggested steps from above such as

aws ecr get-login-password --region eu-west-1 | docker login --username AWS --password-stdin 123456789.dkr.ecr.eu-west-1.amazonaws.com

And always got the no basic auth credentials
I had created a registry named

123456789.dkr.ecr.eu-west-1.amazonaws.com/my.registry.com/namespace 

and was trying to push an image called alpine:latest

123456789.dkr.ecr.eu-west-1.amazonaws.com/my.registry.com/namespace/alpine:latest

1ca55f6ab4: Preparing
b6fd41c05e: Waiting
ad44a79b33: Waiting
2ce3c1888d: Waiting
no basic auth credentials   

Silly mistake on my behalf as I must create a registry in ecr using the full container path.
I created a new registry using the full container path, not ending on the namespace

123456789.dkr.ecr.eu-west-1.amazonaws.com/my.registry.com/namespace/alpine

and low and behold pushing to

123456789.dkr.ecr.eu-west-1.amazonaws.com/my.registry.com/namespace/alpine:latest 
The push refers to repository [123456789.dkr.ecr.eu-west-1.amazonaws.com/my.registry.com/namespace/alpine]

There are a couple of methods for full mysql FULL [OUTER] JOIN.

1. UNION a left join and right join. UNION will remove duplicates by performing an ORDER BY operation. So depending on your data, it may not be performant.

    SELECT * FROM A 
      LEFT JOIN B ON A.key = B.key 
   
    UNION 
   
    SELECT * FROM A 
      RIGHT JOIN B ON A.key = B.key
   

2. UNION ALL a left join and right EXCLUDING join (that's the lower right figure in the diagram). UNION ALL will not remove duplicates. Sometimes this might be the behaviour that you want. You also want to use RIGHT EXCLUDING to avoid duplicating common records from selection A and selection B - i.e Left join has already included common records from selection B, lets not repeat that again with the right join.

    SELECT * FROM A 
      LEFT JOIN B ON A.key = B.key 
   
    UNION ALL
   
    SELECT * FROM A 
      RIGHT JOIN B ON A.key = B.key
      WHERE A.key IS NULL
   

Similar answer to iHulk's one, but in Swift

Add a file named UIView.swift in your project (or just paste this in any file) :

import UIKit

@IBDesignable extension UIView {
    @IBInspectable var borderColor: UIColor? {
        set {
            layer.borderColor = newValue?.cgColor
        }
        get {
            guard let color = layer.borderColor else {
                return nil
            }
            return UIColor(cgColor: color)
        }
    }
    @IBInspectable var borderWidth: CGFloat {
        set {
            layer.borderWidth = newValue
        }
        get {
            return layer.borderWidth
        }
    }
    @IBInspectable var cornerRadius: CGFloat {
        set {
            layer.cornerRadius = newValue
            clipsToBounds = newValue > 0
        }
        get {
            return layer.cornerRadius
        }
    }
}

Then this will be available in Interface Builder for every button, imageView, label, etc. in the Utilities Panel > Attributes Inspector :

Note: the border will only appear at runtime.

I like to use np.vectorize for such tasks. Consider the following:

>>> # function which returns True when constraints are satisfied.
>>> func = lambda d: d >= r and d<= (r+dr) 
>>>
>>> # Apply constraints element-wise to the dists array.
>>> result = np.vectorize(func)(dists) 
>>>
>>> result = np.where(result) # Get output.

You can also use np.argwhere instead of np.where for clear output. But that is your call :)

Hope it helps.

My 2¢! Really, part of the reason I'm throwing this up here, despite the long list of answers, is to provide a little more all in one type solution and get some feed back in the future on how to expand it to include more real types.

With the following solution, as aforementioned, I combined a couple of solutions found here, as well as incorporate a fix for returning a value of jQuery on jQuery defined object if available. I also append the method to the native Object prototype. I know that is often taboo, as it could interfere with other such extensions, but I leave that to user beware. If you don't like this way of doing it, simply copy the base function anywhere you like and replace all variables of this with an argument parameter to pass in (such as arguments[0]).

;(function() {  //  Object.realType
    function realType(toLower) {
        var r = typeof this;
        try {
            if (window.hasOwnProperty('jQuery') && this.constructor && this.constructor == jQuery) r = 'jQuery';
            else r = this.constructor && this.constructor.name ? this.constructor.name : Object.prototype.toString.call(this).slice(8, -1);
        }
        catch(e) { if (this['toString']) r = this.toString().slice(8, -1); }
        return !toLower ? r : r.toLowerCase();
    }
    Object['defineProperty'] && !Object.prototype.hasOwnProperty('realType')
        ? Object.defineProperty(Object.prototype, 'realType', { value: realType }) : Object.prototype['realType'] = realType;
})();

Then simply use with ease, like so:

obj.realType()  //  would return 'Object'
obj.realType(true)  //  would return 'object'

Note: There is 1 argument passable. If is bool of true, then the return will always be in lowercase.

More Examples:

true.realType();                            //  "Boolean"
var a = 4; a.realType();                    //  "Number"
$('div:first').realType();                   // "jQuery"
document.createElement('div').realType()    //  "HTMLDivElement"

If you have anything to add that maybe helpful, such as defining when an object was created with another library (Moo, Proto, Yui, Dojo, etc...) please feel free to comment or edit this and keep it going to be more accurate and precise. OR roll on over to the GitHub I made for it and let me know. You'll also find a quick link to a cdn min file there.

Just modify your WebAPIConfig.cs as bellow

Routes.MapHttpRoute(
  name: "DefaultApi",
  routeTemplate: "api/{controller}/{action}/{id}",
  defaults: new { action = "get", id = RouteParameter.Optional });

Then implement your API as bellow

    // GET: api/Controller_Name/Show/1
    [ActionName("Show")]
    [HttpGet]
    public EventPlanner Id(int id){}

The Extended WPF Toolkit has one: NumericUpDown

Basically same as the accepted answer, but updated with new type and multiple country restrictions:

function initialize() {

 var options = {
  types: ['(regions)'],
  componentRestrictions: {country: ["us", "de"]}
 };

 var input = document.getElementById('searchTextField');
 var autocomplete = new google.maps.places.Autocomplete(input, options);
}

Using '(regions)' instead of '(cities)' allows to search by postal code as well as city name.

See official documentation, Table 3: https://developers.google.com/places/supported_types

This is for Mac OS X with the native installation of Apache HTTP and custom installation of MySQL.

The answer is based on @alec-gorge's excellent response, but since I had to google some specific changes to have it configured in my configuration, mostly Mac OS X-specific, I thought I'd add it here for the sake of completeness.

Enable PHP5 support for Apache HTTP

Make sure the PHP5 support is enabled in /etc/apache2/httpd.conf.

Edit the file with sudo vi /etc/apache2/httpd.conf (enter the password when asked) and uncomment (remove ; from the beginning of) the line to load the php5_module module.

LoadModule php5_module libexec/apache2/libphp5.so

Start Apache HTTP with sudo apachectl start (or restart if it's already started and needs to be restarted to re-read the configuration file).

Make sure that /var/log/apache2/error_log contains a line that tells you the php5_module is enabled - you should see PHP/5.3.15 (or similar).

[notice] Apache/2.2.22 (Unix) DAV/2 PHP/5.3.15 with Suhosin-Patch configured -- resuming normal operations

Looking up Socket file's name

When MySQL is up and running (with ./bin/mysqld_safe) there should be debug lines printed out to the console that tell you where you can find the log files. Note the hostname in the file name - localhost in my case - that may be different for your configuration.

The file that comes after Logging to is important. That's where MySQL logs its work.

130309 12:17:59 mysqld_safe Logging to '/Users/jacek/apps/mysql/data/localhost.err'.
130309 12:17:59 mysqld_safe Starting mysqld daemon with databases from /Users/jacek/apps/mysql/data

Open the localhost.err file (again, yours might be named differently), i.e. tail -1 /Users/jacek/apps/mysql/data/localhost.err to find out the socket file's name - it should be the last line.

$ tail -1 /Users/jacek/apps/mysql/data/localhost.err
Version: '5.5.27'  socket: '/tmp/mysql.sock'  port: 3306  MySQL Community Server (GPL)

Note the socket: part - that's the socket file you should use in php.ini.

There's another way (some say an easier way) to determine the location of the socket's file name by logging in to MySQL and running:

show variables like '%socket%';

Configuring PHP5 with MySQL support - /etc/php.ini

Speaking of php.ini...

In /etc directory there's /etc/php.ini.default file. Copy it to /etc/php.ini.

sudo cp /etc/php.ini.default /etc/php.ini

Open /etc/php.ini and look for mysql.default_socket.

sudo vi /etc/php.ini

The default of mysql.default_socket is /var/mysql/mysql.sock. You should change it to the value you have noted earlier - it was /tmp/mysql.sock in my case.

Replace the /etc/php.ini file to reflect the socket file's name:

mysql.default_socket = /tmp/mysql.sock
mysqli.default_socket = /tmp/mysql.sock

Final verification

Restart Apache HTTP.

sudo apachectl restart 

Check the logs if there are no error related to PHP5. No errors means you're done and PHP5 with MySQL should work fine. Congrats!

From MSDN:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

The only difference is that CHARACTER VARYING is more human friendly than VARCHAR

I have build a small demo project on this you could have a look to it Link to project

ctypes can be used to access dlls, here's a tutorial:

http://docs.python.org/library/ctypes.html#module-ctypes

If you only want to check whether it's a string or not, you can place the "out int" keywords directly inside a method call. According to dotnetperls.com website, older versions of C# do not allow this syntax. By doing this, you can reduce the line count of the program.

string x = "text or int";
if (int.TryParse(x, out int output))
{
  // Console.WriteLine(x);
  // x is an int
  // Do something
}
else
{
  // x is not an int
}

If you also want to get the int values, you can write like this.

Method 1

string x = "text or int";
int value = 0;
if(int.TryParse(x, out value))
{
  // x is an int
  // Do something
}
  else
{
  // x is not an int
}

Method 2

string x = "text or int";
int num = Convert.ToInt32(x);
Console.WriteLine(num);

Referece: https://www.dotnetperls.com/parse

Starting with C# 8.0, you can create and consume streams asynchronously.

    private async void button1_Click(object sender, EventArgs e)
    {
        IAsyncEnumerable<int> enumerable = GenerateSequence();

        await foreach (var i in enumerable)
        {
            Debug.WriteLine(i);
        }
    }

    public static async IAsyncEnumerable<int> GenerateSequence()
    {
        for (int i = 0; i < 20; i++)
        {
            await Task.Delay(100);
            yield return i;
        }
    }

Yes, rightly said. Hive does not support UPDATE option. But the following alternative could be used to achieve the result:

Update records in a partitioned Hive table:

1. The main table is assumed to be partitioned by some key.
2. Load the incremental data (the data to be updated) to a staging table partitioned with the same keys as the main table.

3. Join the two tables (main & staging tables) using a LEFT OUTER JOIN operation as below:

   insert overwrite table main_table partition (c,d) select t2.a, t2.b, t2.c,t2.d from staging_table t2 left outer join main_table t1 on t1.a=t2.a;

In the above example, the main_table & the staging_table are partitioned using the (c,d) keys. The tables are joined via a LEFT OUTER JOIN and the result is used to OVERWRITE the partitions in the main_table.

A similar approach could be used in the case of un-partitioned Hive table UPDATE operations too.

I've faced it a few times, mostly in unit testing or in a windows service development. Currently I always use this feature:

        var runSync = Task.Factory.StartNew(new Func<Task>(async () =>
        {
            Trace.WriteLine("Task runSync Start");
            await TaskEx.Delay(2000); // Simulates a method that returns a task and
                                      // inside it is possible that there
                                      // async keywords or anothers tasks
            Trace.WriteLine("Task runSync Completed");
        })).Unwrap();
        Trace.WriteLine("Before runSync Wait");
        runSync.Wait();
        Trace.WriteLine("After runSync Waited");

It's simple, easy and I had no problems.

It would be better if you just used an AsyncTask running using a Timer something like this

 Timer LAIATT = new Timer();
    TimerTask LAIATTT = new TimerTask()
    {
        @Override
        public void run()
        {
            LoadAccountInformationAsyncTask LAIAT = new LoadAccountInformationAsyncTask();
            LAIAT.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
        }
    };
    LAIATT.schedule(LAIATTT, 0, 1000);

Mysql has this handy UPDATE INTO command ;)

edit Looks like they renamed it to REPLACE

REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted

In your first example, you are correct. The batch will hit the commit transaction, regardless of whether the try block fires.

In your second example, I agree with other commenters. Using the success flag is unnecessary.

I consider the following approach to be, essentially, a light weight best practice approach.

If you want to see how it handles an exception, change the value on the second insert from 255 to 256.

CREATE TABLE #TEMP ( ID TINYINT NOT NULL );
INSERT  INTO #TEMP( ID ) VALUES  ( 1 )

BEGIN TRY
    BEGIN TRANSACTION

    INSERT  INTO #TEMP( ID ) VALUES  ( 2 )
    INSERT  INTO #TEMP( ID ) VALUES  ( 255 )

    COMMIT TRANSACTION
END TRY
BEGIN CATCH
    DECLARE 
        @ErrorMessage NVARCHAR(4000),
        @ErrorSeverity INT,
        @ErrorState INT;
    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();
    RAISERROR (
        @ErrorMessage,
        @ErrorSeverity,
        @ErrorState    
        );
    ROLLBACK TRANSACTION
END CATCH

SET NOCOUNT ON

SELECT ID
FROM #TEMP

DROP TABLE #TEMP

Stored procedures can be executed like below

 string cmd = Constants.StoredProcs.usp_AddRoles.ToString() + " @userId, @roleIdList";
                        int result = db.Database
                                       .ExecuteSqlCommand
                                       (
                                          cmd,
                                           new SqlParameter("@userId", userId),
                                           new SqlParameter("@roleIdList", roleId)
                                       );

One more way to do this is:

git config remote.origin.url https://github.com/abc/abc.git

To see the existing URL just do:

git config remote.origin.url

No -- AL is the 8 least significant bits of AX. AX is the 16 least significant bits of EAX.

Perhaps it's easiest to deal with if we start with 04030201h in eax. In this case, AX will contain 0201h, AH wil contain 02h and AL will contain 01h.

Canonical without using frameworks with added trim prototype for older browsers

<html>
<head>
<script type="text/javascript">
// add trim to older IEs
if (!String.trim) {
  String.prototype.trim = function() {return this.replace(/^\s+|\s+$/g, "");};
}

window.onload=function() { // onobtrusively adding the submit handler
  document.getElementById("form1").onsubmit=function() { // needs an ID
    var val = this.textField1.value; // 'this' is the form 
    if (val==null || val.trim()=="") { 
      alert('Please enter something');
      this.textField1.focus();
      return false; // cancel submission
    }
    return true; // allow submit
  }
}
</script>
</head>
<body>
<form id="form1">
  <input type="text" name="textField1" value="" /><br/>
  <input type="submit" />
</form>
</body>
</html>

Here is the inline version, although not recommended I show it here in case you need to add validation without being able to refactor the code

function validate(theForm) { // passing the form object
  var val = theForm.textField1.value;
  if (val==null || val.trim()=="") { 
    alert('Please enter something');
    theForm.textField1.focus();
    return false; // cancel submission
  }
  return true; // allow submit
}

passing the form object in (this)

<form onsubmit="return validate(this)">
  <input type="text" name="textField1" value="" /><br/>
  <input type="submit" />
</form>

if (window.location.href.indexOf("franky") != -1)

would do it. Alternatively, you could use a regexp:

if (/franky/.test(window.location.href))

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

You can start with a custom number and increment from there, for example you want to add a cheque number for each payment you can do:

select @StartChequeNumber = 3446;
SELECT 
((ROW_NUMBER() OVER(ORDER BY AnyColumn)) + @StartChequeNumber ) AS 'ChequeNumber'
,* FROM YourTable

will give the correct cheque number for each row.

OK, normally it does not a good practice to add 2 answers in same thread, but I did not want to edit/delete my previous answer, since it can help on another manner.

Now, I created, much more comprehensive, and easy to understand, run-to-learn console app snippet below.

Just run the examples on two different consoles, and observe behaviour. You will get much more clear idea there what is happening behind the scenes.

            }
            Console.WriteLine("Worker3 is DONE. ThreadId: {0}", Thread.CurrentThread.ManagedThreadId);
        }

ORA-06512 is part of the error stack. It gives us the line number where the exception occurred, but not the cause of the exception. That is usually indicated in the rest of the stack (which you have still not posted).

In a comment you said

"still, the error comes when pNum is not between 12 and 14; when pNum is between 12 and 14 it does not fail"

Well, your code does this:

IF ((pNum < 12) OR (pNum > 14)) THEN     
    RAISE vSOME_EX;

That is, it raises an exception when pNum is not between 12 and 14. So does the rest of the error stack include this line?

ORA-06510: PL/SQL: unhandled user-defined exception

If so, all you need to do is add an exception block to handle the error. Perhaps:

PROCEDURE PX(pNum INT,pIdM INT,pCv VARCHAR2,pSup FLOAT)
AS
    vSOME_EX EXCEPTION;

BEGIN 
    IF ((pNum < 12) OR (pNum > 14)) THEN     
        RAISE vSOME_EX;
    ELSE  
        EXECUTE IMMEDIATE  'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('||pCv||', '||pSup||', '||pIdM||')';
    END IF;
exception
    when vsome_ex then
         raise_application_error(-20000
                                 , 'This is not a valid table:  M'||pNum||'GR');

END PX;

The documentation covers handling PL/SQL exceptions in depth.

• Find out more.

When you call for i in a:, you are getting the actual elements, not the indexes. When we reach the last element, that is 3, b.append(a[i+1]-a[i]) looks for a[4], doesn't find one and then fails. Instead, try iterating over the indexes while stopping just short of the last one, like

for i in range(0, len(a)-1): Do something

Your current code won't work yet for the do something part though ;)

Most of the time you can just npm update (or yarn upgrade) a module to get the latest non breaking changes (respecting the semver specified in your package.json) (<-- read that last part again).

npm update browser-sync
-------
yarn upgrade browser-sync

• Use npm|yarn outdated to see which modules have newer versions
• Use npm update|yarn upgrade (without a package name) to update all modules
• Include --save-dev|--dev if you want to save the newer version numbers to your package.json. (NOTE: as of npm v5.0 this is only necessary for devDependencies).

Major version upgrades:

In your case, it looks like you want the next major version (v2.x.x), which is likely to have breaking changes and you will need to update your app to accommodate those changes. You can install/save the latest 2.x.x by doing:

npm install browser-sync@2 --save-dev
-------
yarn add browser-sync@2 --dev

...or the latest 2.1.x by doing:

npm install [email protected] --save-dev
-------
yarn add [email protected] --dev

...or the latest and greatest by doing:

npm install browser-sync@latest --save-dev
-------
yarn add browser-sync@latest --dev

Note: the last one is no different than doing this:

npm uninstall browser-sync --save-dev
npm install browser-sync --save-dev
-------
yarn remove browser-sync --dev
yarn add browser-sync --dev

The --save-dev part is important. This will uninstall it, remove the value from your package.json, and then reinstall the latest version and save the new value to your package.json.

This will help you.

UPDATE play_school_data SET title= REPLACE(title, "'", "'") WHERE title = "Elmer's Parade";

You can either using hardcoded json attribute as key, or you can conveniently using GuzzleHttp\RequestOptions::JSON constant.

Here is the example of using hardcoded json string.

use GuzzleHttp\Client;

$client = new Client();

$response = $client->post('url', [
    'json' => ['foo' => 'bar']
]);

See Docs.

The entire transmission, including the query string, the whole URL, and even the type of request (GET, POST, etc.) is encrypted when using HTTPS.

You could just give the first cell (therefore column) a width and have the rest default to auto

table {_x000D_
  table-layout: fixed;_x000D_
  border-collapse: collapse;_x000D_
  width: 100%;_x000D_
}_x000D_
td {_x000D_
  border: 1px solid #000;_x000D_
  width: 150px;_x000D_
}_x000D_
td+td {_x000D_
  width: auto;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>150px</td>_x000D_
    <td>equal</td>_x000D_
    <td>equal</td>_x000D_
  </tr>_x000D_
</table>

or alternatively the "proper way" to get column widths might be to use the col element itself

table {_x000D_
  table-layout: fixed;_x000D_
  border-collapse: collapse;_x000D_
  width: 100%;_x000D_
}_x000D_
td {_x000D_
  border: 1px solid #000;_x000D_
}_x000D_
.wide {_x000D_
  width: 150px;_x000D_
}

<table>_x000D_
  <col span="1" class="wide">_x000D_
    <tr>_x000D_
      <td>150px</td>_x000D_
      <td>equal</td>_x000D_
      <td>equal</td>_x000D_
    </tr>_x000D_
</table>

Thread dumps are javacore show snapshot of threads running in JVM, it is useful to debug hang issues, it will provide info about java level dead locks and also IBm version of javacores provides much more useful information, such as heap usage, CPU usage of each thread and overall heap usage along with number of classes laded by the JVM.

Heapdumps, provides information about Java heap usage by an JVM, which can be used to debug memory leaks. Heapdumps are generated by IBM JVMs when a JVM is runs into outofmemoryerror, Heapdumps are only for heap leaks in java, native out of memory error may result system dumps usually with an "GPF" General protection Fault.

You want to do #include <string> instead of string.h and then the type string lives in the std namespace, so you will need to use std::string to refer to it.

SELECT author FROM lyrics WHERE author LIKE 'B%';

Make sure you have an index on author, though!

Edit: See Jayprakash Dubey's answer for iTunes 12.7

From the menu shown in the following screenshot, choose Apps. You can drag and drop you IPA file in the next view.

After that, go to your device's page, you'll see the list of apps, install your app and press Apply from the bottom bar.

A simple solution (assuming you're using a decent IDE) is to just type 'int' everywhere and then get it to set the type for you.

I actually just added a class called 'var' so I don't have to type something different.

The code is still too verbose, but at least you don't have to type it!

This works instantly. Without delay.

// wait for the scroll view to be laid out
scrollView.post(new Runnable() {
  public void run() {
    // then wait for the child of the scroll view (normally a LinearLayout) to be laid out
    scrollView.getChildAt(0).post(new Runnable() {
      public void run() {
        // finally scroll without animation
        scrollView.scrollTo(0, scrollView.getBottom());
      }
    }
  }
}

Just close all the python files opened. And try to run as administrator. It will work.

e.g.

pip install mitmproxy

Create an extension method?

Console.WriteLine(value.ToGBString());

// ...

    }
}

Although the question has been answered, let me mention some nuances.

Let's say you are interested in the first column of the array

arr = numpy.array([[1, 2],
                   [3, 4],
                   [5, 6]])

As you already know from other answers, to get it in the form of "row vector" (array of shape (3,)), you use slicing:

arr_col1_view = arr[:, 1]         # creates a view of the 1st column of the arr
arr_col1_copy = arr[:, 1].copy()  # creates a copy of the 1st column of the arr

To check if an array is a view or a copy of another array you can do the following:

arr_col1_view.base is arr  # True
arr_col1_copy.base is arr  # False

see ndarray.base.

Besides the obvious difference between the two (modifying arr_col1_view will affect the arr), the number of byte-steps for traversing each of them is different:

arr_col1_view.strides[0]  # 8 bytes
arr_col1_copy.strides[0]  # 4 bytes

see strides and this answer.

Why is this important? Imagine that you have a very big array A instead of the arr:

A = np.random.randint(2, size=(10000, 10000), dtype='int32')
A_col1_view = A[:, 1] 
A_col1_copy = A[:, 1].copy()

and you want to compute the sum of all the elements of the first column, i.e. A_col1_view.sum() or A_col1_copy.sum(). Using the copied version is much faster:

%timeit A_col1_view.sum()  # ~248 µs
%timeit A_col1_copy.sum()  # ~12.8 µs

This is due to the different number of strides mentioned before:

A_col1_view.strides[0]  # 40000 bytes
A_col1_copy.strides[0]  # 4 bytes

Although it might seem that using column copies is better, it is not always true for the reason that making a copy takes time too and uses more memory (in this case it took me approx. 200 µs to create the A_col1_copy). However if we needed the copy in the first place, or we need to do many different operations on a specific column of the array and we are ok with sacrificing memory for speed, then making a copy is the way to go.

In the case we are interested in working mostly with columns, it could be a good idea to create our array in column-major ('F') order instead of the row-major ('C') order (which is the default), and then do the slicing as before to get a column without copying it:

A = np.asfortranarray(A)   # or np.array(A, order='F')
A_col1_view = A[:, 1]
A_col1_view.strides[0]     # 4 bytes

%timeit A_col1_view.sum()  # ~12.6 µs vs ~248 µs

Now, performing the sum operation (or any other) on a column-view is as fast as performing it on a column copy.

Finally let me note that transposing an array and using row-slicing is the same as using the column-slicing on the original array, because transposing is done by just swapping the shape and the strides of the original array.

A[:, 1].strides[0]    # 40000 bytes
A.T[1, :].strides[0]  # 40000 bytes

A cleaner way is to set connectionString in xml file, for example Web.Confing(WepApplication) or App.Config(StandAloneApplication).

 <connectionStrings>
    <remove name="myConn"/>
    <add name="myConn" connectionString="User ID=sa;Password=XXXXX;Initial Catalog=qualitaBorri;Data Source=PC_NAME\SQLEXPRESS;Connection Timeout=60"/>
  </connectionStrings>

By code you can get connection in this way:

public static SqlConnection getConnection()
{
        string conn = string.Empty;
        conn = System.Configuration.ConfigurationManager.ConnectionStrings["myConn"].ConnectionString;
        SqlConnection aConnection = new SqlConnection(conn);
        return aConnection;
}

You can set ConnectionTimeout only you create a instance. When instance is create you don't change this value.

First, Eloquent automatically converts it's timestamps (created_at, updated_at) into carbon objects. You could just use updated_at to get that nice feature, or specify edited_at in your model in the $dates property:

protected $dates = ['edited_at'];

Now back to your actual question. Carbon has a bunch of comparison functions:

• eq() equals
• ne() not equals
• gt() greater than
• gte() greater than or equals
• lt() less than
• lte() less than or equals

Usage:

if($model->edited_at->gt($model->created_at)){
    // edited at is newer than created at
}

There is a free and open-source GUI tool KeyStore Explorer to work with crypto key containers. Using it you can export a certificate or private key into separate files or convert the container into another format (jks, pem, p12, pkcs12, etc)

Methods addOption(data) and setValue(value) might be what you are looking for.

Update: Seeing the popularity of this answer, here is some additional info based on comments/requests...

setValue(value, silent)
Resets the selected items to the given value.
If "silent" is truthy (ie: true, 1), no change event will be fired on the original input.

addOption(data)
Adds an available option, or array of options. If it already exists, nothing will happen.
Note: this does not refresh the options list dropdown (use refreshOptions() for that).

In response to options being overwritten:
This can happen by re-initializing the select without using the options you initially provided. If you are not intending to recreate the element, simply store the selectize object to a variable:

// 1. Only set the below variables once (ideally)
var $select = $('select').selectize(options);  // This initializes the selectize control
var selectize = $select[0].selectize; // This stores the selectize object to a variable (with name 'selectize')

// 2. Access the selectize object with methods later, for ex:
selectize.addOption(data);
selectize.setValue('something', false);


// Side note:
// You can set a variable to the previous options with
var old_options = selectize.settings;
// If you intend on calling $('select').selectize(old_options) or something

You can add a class declaration to the submit button of a form by doing the following:

<%= f.submit class: 'btn btn-default' %> <-- Note: there is no comma!

If you are altering a _form.html.erb partial of a scaffold and you want to keep the dynamic change of the button name between controller actions, DO NOT specify a name 'name'.

Without specifying a name and depending on the action the form is rendered the button will get the .class = "btn btn-default" (Bootstrap class)(or whatever .class you specify) with the following names:

• Update model_name

• Create model_name
  (where model_name the name of the scaffold's model)

you can also add inline css for adding image as a background as per below example

<div class="item active" style="background-image: url(../../foo.png);">

This is an example, that, if a condition exist, then terminate the script. I use this in my SSE client side javascript, if the

<script src="sse-clint.js" host="https://sse.host" query='["q1,"q2"]' ></script>

canot be parsed right from JSON parse ...

if( ! SSE_HOST  ) throw new Error(['[!] SSE.js: ERR_NOHOST - finished !']);

... anyway the general idea is:

if( error==true) throw new Error([ 'You have This error' ,  'At this file', 'At this line'  ]);

this will terminate/die your javasript script

Similar to the accepted solution, but you can replace the

let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton

with

let button = UIButton()

Here is the full solution, enjoy: (it's just a bit cleaner than the accepted solution)

let button = UIButton()
button.frame = CGRectMake(0, 0, 51, 31) //won't work if you don't set frame
button.setImage(UIImage(named: "fb"), forState: .Normal)
button.addTarget(self, action: Selector("fbButtonPressed"), forControlEvents: .TouchUpInside)

let barButton = UIBarButtonItem()
barButton.customView = button
self.navigationItem.rightBarButtonItem = barButton

If all you want is calling ravel on your (nested, I s'pose?) list, you can do that directly, numpy will do the casting for you:

L = [[1,None,3],["The", "quick", object]]
np.ravel(L)
# array([1, None, 3, 'The', 'quick', <class 'object'>], dtype=object)

Also worth mentioning that you needn't go through numpy at all.

In Kotlin on the back press to exit app you can use:

Define a global variable:

private var doubleBackToExitPressedOnce = false

Override onBackPressed:

override fun onBackPressed() {
        if (doubleBackToExitPressedOnce) {
            super.onBackPressed()
            return
        }

        doubleBackToExitPressedOnce = true
        Toast.makeText(this, "Please click BACK again to exit", Toast.LENGTH_LONG).show()

        Handler().postDelayed({
            doubleBackToExitPressedOnce = false;
        }, 2000)
    }

if (date.isBefore(endDate) 
 && date.isAfter(startDate) 
 || (date.isSame(startDate) || date.isSame(endDate))

is logically the same as

if (!(date.isBefore(startDate) || date.isAfter(endDate)))

which saves you a couple of lines of code and (in some cases) method calls.

Might be easier than pulling in a whole plugin if you only want to do this once or twice.

Actually it happens when the number of processes exceeds the limits set by the hosting provider.

To avoid either we need to enhance the capacity by hosting providers or we need to check in the code whether any process takes longer time (like background tasks).

Simplest method is the one I would use.

=(ThisYear - LastYear)/(ABS(LastYear))

However it only works in certain situations. With certain values the results will be inverted.

May be your dependencies not build correctly. Check compilation issue in project.

Clean and rebuild project.

For maven project: mvn clean install

For gradle projects: gradle clean build or gradlew clean build

From https://stackoverflow.com/a/2434094/848072. You need a default constructor for T class.

import java.lang.reflect.ParameterizedType;

class Foo {

  public bar() {
    ParameterizedType superClass = (ParameterizedType) getClass().getGenericSuperclass();
    Class type = (Class) superClass.getActualTypeArguments()[0];
    try {
      T t = type.newInstance();
      //Do whatever with t
    } catch (Exception e) {
      // Oops, no default constructor
      throw new RuntimeException(e);
    } 
  }
}

If you want not to type class name twice during instantiation like in:

new SomeContainer<SomeType>(SomeType.class);

You can use factory method:

<E> SomeContainer<E> createContainer(Class<E> class); 

Like in:

public class Container<E> {

    public static <E> Container<E> create(Class<E> c) {
        return new Container<E>(c);
    }

    Class<E> c;

    public Container(Class<E> c) {
        super();
        this.c = c;
    }

    public E createInstance()
            throws InstantiationException,
            IllegalAccessException {
        return c.newInstance();
    }

}

I really wanted to respond to @Sev's answer.

Sev is right, there is a bug inside the window.history.replaceState

To fix this simply rewrite the constructor to set the title manually.

var replaceState_tmp = window.history.replaceState.constructor;
window.history.replaceState.constructor = function(obj, title, url){
    var title_ = document.getElementsByTagName('title')[0];
    if(title_ != undefined){
        title_.innerHTML = title;
    }else{
        var title__ = document.createElement('title');
        title__.innerHTML = title;
        var head_ = document.getElementsByTagName('head')[0];
        if(head_ != undefined){
            head_.appendChild(title__);
        }else{
            var head__ = document.createElement('head');
            document.documentElement.appendChild(head__);
            head__.appendChild(title__);
        }
    }
    replaceState_tmp(obj,title, url);
}

Here's some sample code. This worked for me.

<LinearLayout
    android:gravity="center"
    >
    <TextView
        android:layout_gravity="center"
        />
    <Button
        android:layout_gravity="center"
        />
</LinearLayout>

So you're designing the Linear Layout to place all its contents (TextView and Button) in its center, and then the TextView and Button are placed relative to the center of the Linear Layout.

Modulus method is the usual method. We can also do this to check if odd or even:

def f(a):
    if (a//2)*2 == a:
        return 'even'
    else:
        return 'odd'

Integer division by 2 followed by multiplication by two.

I'm using MVC3/EntityFramework as back-end, the front-end consumes all of my project controllers via jquery, posting directly (using $.post) doesnt requires the data encription, when you pass params directly other than URL hardcoded. I already tested several chars i even sent an URL(this one http://www.ihackforfun.eu/index.php?title=update-on-url-crazy&more=1&c=1&tb=1&pb=1) as a parameter and had no issue at all even though encodeURIComponent works great when you pass all data in within the URL (hardcoded)

Hardcoded URL i.e.>

 var encodedName = encodeURIComponent(name);
 var url = "ControllerName/ActionName/" + encodedName + "/" + keyword + "/" + description + "/" + linkUrl + "/" + includeMetrics + "/" + typeTask + "/" + project + "/" + userCreated + "/" + userModified + "/" + status + "/" + parent;; // + name + "/" + keyword + "/" + description + "/" + linkUrl + "/" + includeMetrics + "/" + typeTask + "/" + project + "/" + userCreated + "/" + userModified + "/" + status + "/" + parent;

Otherwise dont use encodeURIComponent and instead try passing params in within the ajax post method

 var url = "ControllerName/ActionName/";   
 $.post(url,
        { name: nameVal, fkKeyword: keyword, description: descriptionVal, linkUrl: linkUrlVal, includeMetrics: includeMetricsVal, FKTypeTask: typeTask, FKProject: project, FKUserCreated: userCreated, FKUserModified: userModified, FKStatus: status, FKParent: parent },
 function (data) {.......});

Simply you can target a Migration by value

The error

When code is parsed by the JavaScript interpreter, it gets broken into pieces called "tokens". When a token cannot be classified into one of the four basic token types, it gets labelled "ILLEGAL" on most implementations, and this error is thrown.

The same error is raised if, for example, you try to run a js file with a rogue @ character, a misplaced curly brace, bracket, "smart quotes", single quotes not enclosed properly (e.g. this.run('dev1)) and so on.

A lot of different situations can cause this error. But if you don't have any obvious syntax error or illegal character, it may be caused by an invisible illegal character. That's what this answer is about.

But I can't see anything illegal!

There is an invisible character in the code, right after the semicolon. It's the Unicode U+200B Zero-width space character (a.k.a. ZWSP, HTML entity ​). That character is known to cause the Unexpected token ILLEGAL JavaScript syntax error.

And where did it come from?

I can't tell for sure, but my bet is on jsfiddle. If you paste code from there, it's very likely to include one or more U+200B characters. It seems the tool uses that character to control word-wrapping on long strings.

UPDATE 2013-01-07

After the latest jsfiddle update, it's now showing the character as a red dot like codepen does. Apparently, it's also not inserting U+200B characters on its own anymore, so this problem should be less frequent from now on.

UPDATE 2015-03-17

Vagrant appears to sometimes cause this issue as well, due to a bug in VirtualBox. The solution, as per this blog post is to set sendfile off; in your nginx config, or EnableSendfile Off if you use Apache.

It's also been reported that code pasted from the Chrome developer tools may include that character, but I was unable to reproduce that with the current version (22.0.1229.79 on OSX).

How can I spot it?

The character is invisible, do how do we know it's there? You can ask your editor to show invisible characters. Most text editors have this feature. Vim, for example, displays them by default, and the ZWSP shows as <u200b>. You can also debug it online: jsbin displays the character as a red dot on its code panes (but seems to remove it after saving and reloading the page). CodePen.io also displays it as a dot, and keeps it even after saving.

Related problems

That character is not something bad, it can actually be quite useful. This example on Wikipedia demonstrates how it can be used to control where a long string should be wrapped to the next line. However, if you are unaware of the character's presence on your markup, it may become a problem. If you have it inside of a string (e.g., the nodeValue of a DOM element that has no visible content), you might expect such string to be empty, when in fact it's not (even after applying String.trim).

ZWSP can also cause extra whitespace to be displayed on an HTML page, for example when it's found between two <div> elements (as seen on this question). This case is not even reproducible on jsfiddle, since the character is ignored there.

Another potential problem: if the web page's encoding is not recognized as UTF-8, the character may actually be displayed (as ​ in latin1, for example).

If ZWSP is present on CSS code (inline code, or an external stylesheet), styles can also not be parsed properly, so some styles don't get applied (as seen on this question).

The ECMAScript Specification

I couldn't find any mention to that specific character on the ECMAScript Specification (versions 3 and 5.1). The current version mentions similar characters (U+200C and U+200D) on Section 7.1, which says they should be treated as IdentifierParts when "outside of comments, string literals, and regular expression literals". Those characters may, for example, be part of a variable name (and var x\u200c; indeed works).

Section 7.2 lists the valid White space characters (such as tab, space, no-break space, etc.), and vaguely mentions that any other Unicode “space separator” (category “Zs”) should be treated as white space. I'm probably not the best person to discuss the specs in this regard, but it seems to me that U+200B should be considered white space according to that, when in fact the implementations (at least Chrome and Firefox) appear to treat them as an unexpected token (or part of one), causing the syntax error.

For future readers who found this question while trying to save high resolution images from matplotlib as I am, I have tried some of the answers above and elsewhere, and summed them up here.

Best result: plt.savefig('filename.pdf')

and then converting this pdf to a png on the command line so you can use it in powerpoint:

pdftoppm -png -r 300 filename.pdf filename

OR simply opening the pdf and cropping to the image you need in adobe, saving as a png and importing the picture to powerpoint

Less successful test #1: plt.savefig('filename.png', dpi=300)

This does save the image at a bit higher than the normal resolution, but it isn't high enough for publication or some presentations. Using a dpi value of up to 2000 still produced blurry images when viewed close up.

Less successful test #2: plt.savefig('filename.pdf')

This cannot be opened in Microsoft Office Professional Plus 2016 (so no powerpoint), same with Google Slides.

Less successful test #3: plt.savefig('filename.svg')

This also cannot be opened in powerpoint or Google Slides, with the same issue as above.

Less successful test #4: plt.savefig('filename.pdf')

and then converting to png on the command line:

convert -density 300 filename.pdf filename.png

but this is still too blurry when viewed close up.

Less successful test #5: plt.savefig('filename.pdf')

and opening in GIMP, and exporting as a high quality png (increased the file size from ~100 KB to ~75 MB)

Less successful test #6: plt.savefig('filename.pdf')

and then converting to jpeg on the command line:

pdfimages -j filename.pdf filename

This did not produce any errors but did not produce an output on Ubuntu even after changing around several parameters.

You have several errors there.

First, you have to return a value from the function in the HTML markup: <form name="ff1" method="post" onsubmit="return validateForm();">

Second, in the JSFiddle, you place the code inside onLoad which and then the form won't recognize it - and last you have to return true from the function if all validation is a success - I fixed some issues in the update:

https://jsfiddle.net/mj68cq0b/

function validateURL(url) {
    var reurl = /^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/;
    return reurl.test(url);
}

function validateForm()
{
    // Validate URL
    var url = $("#frurl").val();
    if (validateURL(url)) { } else {
        alert("Please enter a valid URL, remember including http://");
        return false;
    }

    // Validate Title
    var title = $("#frtitle").val();
    if (title=="" || title==null) {
        alert("Please enter only alphanumeric values for your advertisement title");
        return false;
    }

    // Validate Email
    var email = $("#fremail").val();
    if ((/(.+)@(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email==null) { } else {
        alert("Please enter a valid email");
        return false;
    }
  return true;
}

In JavaScript Arrays and Objects are actually very similar, although on the outside they can look a bit different.

For an array:

var array = [];
array[0] = "hello";
array[1] = 5498;
array[536] = new Date();

As you can see arrays in JavaScript can be sparse (valid indicies don't have to be consecutive) and they can contain any type of variable! That's pretty convenient.

But as we all know JavaScript is strange, so here are some weird bits:

array["0"] === "hello"; // This is true
array["hi"]; // undefined
array["hi"] = "weird"; // works but does not save any data to array
array["hi"]; // still undefined!

This is because everything in JavaScript is an Object (which is why you can also create an array using new Array()). As a result every index in an array is turned into a string and then stored in an object, so an array is just an object that doesn't allow anyone to store anything with a key that isn't a positive integer.

So what are Objects?

Objects in JavaScript are just like arrays but the "index" can be any string.

var object = {};
object[0] = "hello"; // OK
object["hi"] = "not weird"; // OK

You can even opt to not use the square brackets when working with objects!

console.log(object.hi); // Prints 'not weird'
object.hi = "overwriting 'not weird'";

You can go even further and define objects like so:

var newObject = {
    a: 2,
};
newObject.a === 2; // true

var array = new Uint8Array(100);    
array[10] = 256;
array[10] === 0 // true

I verified in firefox and chrome, its really an array of bytes :

var array = new Uint8Array(1024*1024*50);  // allocates 50MBytes

$("label[for='"+$(this).attr("id")+"']");

This should allow you to select labels for all the fields in a loop as well. All you need to ensure is your labels should say for='FIELD' where FIELD is the id of the field for which this label is being defined.

You should provide a selector to the on function:

$(document).on('change', 'input', function() {
  // Does some stuff and logs the event to the console
});

In that case, it will work as you expected. Also, it is better to specify some element instead of document.

To manually generate a Certificate, you need a Certificate Signing Request (CSR) file from your Mac. To create a CSR file, follow the instructions below to create one using Keychain Access.

Create a CSR file. In the Applications folder on your Mac, open the Utilities folder and launch Keychain Access.

Within the Keychain Access drop down menu, select Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority.

In the Certificate Information window, enter the following information: In the User Email Address field, enter your email address. In the Common Name field, create a name for your private key (e.g., John Doe Dev Key). The CA Email Address field should be left empty. In the "Request is" group, select the "Saved to disk" option. Click Continue within Keychain Access to complete the CSR generating process.

I had the same problem. I was using Windows for creating a react native app for android and was having the same error. Here's what worked.

• Navigate to the folder ANDROID in your root.
• Create a file with name : local.properties
• Open it in editor and write :

sdk.dir = C:\Users\ USERNAME \AppData\Local\Android\sdk

• Replace USERNAME with the name of your machine.

Save and run the app normally. That worked for me.

You can do it in a few ways.All the ways are technically the same but using Lambda would simplify some of the code. Lets say we initialize a List first with String, call it persons.

List<String> persons = new ArrayList<String>(){{add("a"); add("b"); add("c");}};
Stream<String> stream = persons.stream();

Now you can use either of the following ways.

1. Using the Lambda Expresiion to create a new StringArray with defined size.

   String[] stringArray = stream.toArray(size->new String[size]);

2. Using the method reference directly.

   String[] stringArray = stream.toArray(String[]::new);

I created my own snippet that only adds {get; set;}. I made it just because I find prop → Tab to be clunky.

<?xml version="1.0" encoding="utf-8"?>
<CodeSnippets
    xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">
    <CodeSnippet Format="1.0.0">
        <Header>
            <Title>get set</Title>

            </Code>
        </Snippet>
    </CodeSnippet>
</CodeSnippets>

With this, you type your PropType and PropName manually, then type get → Tab, and it will add the get set. It's nothing magical, but since I tend to type my access modifier first anyway, I may as well finish out the name and type.

A nice single-line trick to avoid early variable expansion is to use cmd /c echo ^%time^%

cmd /c echo ^%time^% & dir /s somelongcommand & cmd /c echo ^%time^%

Consider using cellspacing and cellpadding attributes for table tag or border-spacing css property.

The Basics

Look at these to build a solution more or less from scratch:

• Start from the basics: The Java Tutorial's chapter on Networking, including Working With URLs
• Make things easier for yourself: Apache HttpComponents (including HttpClient)

The Easily Glued-Up and Stitched-Up Stuff

You always have the option of calling external tools from Java using the exec() and similar methods. For instance, you could use wget, or cURL.

The Hardcore Stuff

Then if you want to go into more fully-fledged stuff, thankfully the need for automated web-testing as given us very practical tools for this. Look at:

• HtmlUnit (powerful and simple)
• Selenium, Selenium-RC
• WebDriver/Selenium2 (still in the works)
• JBehave with JBehave Web

Some other libs are purposefully written with web-scraping in mind:

• JSoup
• Jaunt

Some Workarounds

Java is a language, but also a platform, with many other languages running on it. Some of which integrate great syntactic sugar or libraries to easily build scrapers.

Check out:

• Groovy (and its XmlSlurper)
• or Scala (with great XML support as presented here and here)

If you know of a great library for Ruby (JRuby, with an article on scraping with JRuby and HtmlUnit) or Python (Jython) or you prefer these languages, then give their JVM ports a chance.

Some Supplements

Some other similar questions:

• Scrape data from HTML using Java
• Options for HTML Scraping

I had this issue so I just took all my content, copy/pasted it into notepad, made a new php file, pasted back in, re-saved and overwrote, and.. that worked! It really was some relic of Microsoft Word editing...

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

           vbNewLine & "Please correct and try again.", vbOKOnly

Try this:-

ALTER TABLE <TABLE NAME to be moved> MOVE TABLESPACE <destination TABLESPACE NAME>

Very nice suggestion from IVAN in comments so thought to add in my answer

Note: this will invalidate all table's indexes. So this command is usually followed by

alter index <owner>."<index_name>" rebuild;

C++ solution found here (http://www.cplusplus.com/forum/unices/16430/)

#include <signal.h>
#include <stdio.h>
#include <unistd.h>
void ouch(int sig)
{
    printf("OUCH! - I got signal %d\n", sig);
}
int main()
{
    struct sigaction act;
    act.sa_handler = ouch;
    sigemptyset(&act.sa_mask);
    act.sa_flags = 0;
    sigaction(SIGINT, &act, 0);
    while(1) {
        printf("Hello World!\n");
        sleep(1);

We store our URLs in a database and load them at runtime.

public class ServiceClientFactory<TChannel> : ClientBase<TChannel> where TChannel : class
{
    public TChannel Create(string url)
    {
        this.Endpoint.Address = new EndpointAddress(new Uri(url));
        return this.Channel;
    }
}

Implementation

var client = new ServiceClientFactory<yourServiceChannelInterface>().Create(newUrl);

The simple way

ALTER DATABASE `oldName` MODIFY NAME = `newName`;

or you can use online sql generator

May be you need "dynamic" type?

public dynamic GetAnything()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();

     return /*what boject you needed*/ ;`enter code here`   
}

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

This worked for me:

export _JAVA_OPTIONS="-Xmx1g"

It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:

java -XshowSettings:vm 

and it will tell you:

Picked up _JAVA_OPTIONS: -Xmx1g

Go to Tools > Options. In the tree on the left, select SQL Server Object Explorer. Set the option "Value for Edit Top Rows command" to 0. It'll now allow you to view and edit the entire table from the context menu.

Signed variables can be 0, positive or negative.

Unsigned variables can be 0 or positive.

Unsigned variables are used sometimes because more bits can be used to represent the actual value. Giving you a larger range. Also you can ensure that a negative value won't be passed to your function for example.

Open DDMS than in DATA>DATA>"Select your package like com.example.foo"> than select your database folder than pull that data in eclipse you can see the pull an push icon on top right side ...

<activity android:name=".yourActivity"
          android:screenOrientation="portrait" ... />

add to main activity and add

android:configChanges="keyboardHidden"

to keep your program from changing mode when keyboard is called.

If you're open to changing the original string, you can simply replace the delimiter with \0. The original pointer will point to the first string and the pointer to the character after the delimiter will point to the second string. The good thing is you can use both pointers at the same time without allocating any new string buffers.

Pass the correct arguments? :P

On the more serious note, you can pass the argument -Wi::DeprecationWarning on the command line to the interpreter to ignore the deprecation warnings.

Just set the width to 100vw like this:

<div id="container" style="width: 100vw">

I can't reproduce your issue running El Cap + Homebrew 1.0.x

Upgrade to Homebrew 1.0.x, which was released late in September. Specific changes were made in the way openssl is linked. The project is on a more robust release schedule now that it's hit 1.0.

brew uninstall openssl

brew update && brew upgrade && brew cleanup && brew doctor

You should fix any issues raised by brew doctor before proceeding.

brew install openssl

Note: Upgrading homebrew will update all your installed packages to their latest versions.

In my case it was due to SSL certificate being signed by internal CA of my company. Using workarounds like pip --cert did not help, but the following package did:

pip install pip_system_certs

See: https://pypi.org/project/pip-system-certs/

This package patches pip and requests at runtime to use certificates from the default system store (rather than the bundled certs ca).

This will allow pip to verify tls/ssl connections to servers who’s cert is trusted by your system install.

Angular Component

A component is one of the basic building blocks of an Angular app. An app can have more than one component. In a normal app, a component contains an HTML view page class file, a class file that controls the behaviour of the HTML page and the CSS/scss file to style your HTML view. A component can be created using @Component decorator that is part of @angular/core module.

import { Component } from '@angular/core';

and to create a component

@Component({selector: 'greet', template: 'Hello {{name}}!'})
class Greet {
  name: string = 'World';
}

To create a component or angular app here is the tutorial

Angular Module

An angular module is set of angular basic building blocks like component, directives, services etc. An app can have more than one module.

A module can be created using @NgModule decorator.

@NgModule({
  imports:      [ BrowserModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

if you are ok with null, undefined, NaN, 0, and false all casting to '' then (s ? s+'' : '') is faster.

see http://jsperf.com/cast-to-string/8

note - there are significant differences across browsers at this time.

In my case it was enough to split the text at every \n and then create a JLabel for every line:

JPanel panel = new JPanel(new GridLayout(0,1));
String[] lines = message.split("\n");
for (String line : lines) {
    JLabel label = new JLabel(line);
    panel.add(label);
}

I used above in a JOptionPane.showMessageDialog

I am going to use a very simple snippet to illustrate the difference:

test = pd.DataFrame({'id':[1,2,3,1,2,3,1,2,3], 'price':[1,2,3,2,3,1,3,1,2]})
grouping = test.groupby('id')['price']

The DataFrame looks like this:

    id  price   
0   1   1   
1   2   2   
2   3   3   
3   1   2   
4   2   3   
5   3   1   
6   1   3   
7   2   1   
8   3   2   

There are 3 customer IDs in this table, each customer made three transactions and paid 1,2,3 dollars each time.

Now, I want to find the minimum payment made by each customer. There are two ways of doing it:

1. Using apply:

   grouping.min()

The return looks like this:

id
1    1
2    1
3    1
Name: price, dtype: int64

pandas.core.series.Series # return type
Int64Index([1, 2, 3], dtype='int64', name='id') #The returned Series' index
# lenght is 3

2. Using transform:

   grouping.transform(min)

The return looks like this:

0    1
1    1
2    1
3    1
4    1
5    1
6    1
7    1
8    1
Name: price, dtype: int64

pandas.core.series.Series # return type
RangeIndex(start=0, stop=9, step=1) # The returned Series' index
# length is 9    

Both methods return a Series object, but the length of the first one is 3 and the length of the second one is 9.

If you want to answer What is the minimum price paid by each customer, then the apply method is the more suitable one to choose.

If you want to answer What is the difference between the amount paid for each transaction vs the minimum payment, then you want to use transform, because:

test['minimum'] = grouping.transform(min) # ceates an extra column filled with minimum payment
test.price - test.minimum # returns the difference for each row

Apply does not work here simply because it returns a Series of size 3, but the original df's length is 9. You cannot integrate it back to the original df easily.

In order to read a file chosen by the user, using a file open dialog, you can use the <input type="file"> tag. You can find information on it from MSDN. When the file is chosen you can use the FileReader API to read the contents.

function onFileLoad(elementId, event) {_x000D_
    document.getElementById(elementId).innerText = event.target.result;_x000D_
}_x000D_
_x000D_
function onChooseFile(event, onLoadFileHandler) {_x000D_
    if (typeof window.FileReader !== 'function')_x000D_
        throw ("The file API isn't supported on this browser.");_x000D_
    let input = event.target;_x000D_
    if (!input)_x000D_
        throw ("The browser does not properly implement the event object");_x000D_
    if (!input.files)_x000D_
        throw ("This browser does not support the `files` property of the file input.");_x000D_
    if (!input.files[0])_x000D_
        return undefined;_x000D_
    let file = input.files[0];_x000D_
    let fr = new FileReader();_x000D_
    fr.onload = onLoadFileHandler;_x000D_
    fr.readAsText(file);_x000D_
}

<input type='file' onchange='onChooseFile(event, onFileLoad.bind(this, "contents"))' />_x000D_

Dart http's implementation process the bytes thanks to that "charset=utf-8", so i'm sure several implementations out there supports this, to avoid the "latin-1" fallback charset when reading the bytes from the response. In my case, I totally lose format on the response body string, so I have to do the bytes encoding manually to utf8, or add that header "inner" parameter on my server's API response.

OK. After a lot of research, combined with the accepted answer above, I have come up with a solution that also works if you have other stuff in your action bar (back/home button, menu button). So basically I have put the override methods in a basic activity (which all other activities extend), and placed the code there. This code sets the title of each activity as it is provided in AndroidManifest.xml, and also does som other custom stuff (like setting a custom tint on action bar buttons, and custom font on the title). You only need to leave out the gravity in action_bar.xml, and use padding instead. actionBar != null check is used, since not all my activities have one.

Tested on 4.4.2 and 5.0.1

public class BaseActivity extends AppCompatActivity {
private ActionBar actionBar;
private TextView actionBarTitle;
private Toolbar toolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS);
    super.onCreate(savedInstanceState);     
    ...
    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

    actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.setElevation(0);
        actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
        actionBar.setCustomView(R.layout.action_bar);

        LinearLayout layout = (LinearLayout) actionBar.getCustomView();
        actionBarTitle = (TextView) layout.getChildAt(0);
        actionBarTitle.setText(this.getTitle());
        actionBarTitle.setTypeface(Utility.getSecondaryFont(this));
        toolbar = (Toolbar) layout.getParent();
        toolbar.setContentInsetsAbsolute(0, 0);

        if (this.getClass() == BackButtonActivity.class || this.getClass() == AnotherBackButtonActivity.class) {
            actionBar.setHomeButtonEnabled(true);
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setDisplayShowHomeEnabled(true);
            Drawable wrapDrawable = DrawableCompat.wrap(getResources().getDrawable(R.drawable.ic_back));
            DrawableCompat.setTint(wrapDrawable, getResources().getColor(android.R.color.white));
            actionBar.setHomeAsUpIndicator(wrapDrawable);
            actionBar.setIcon(null);
        }
        else {
            actionBar.setHomeButtonEnabled(false);
            actionBar.setDisplayHomeAsUpEnabled(false);
            actionBar.setDisplayShowHomeEnabled(false);
            actionBar.setHomeAsUpIndicator(null);
            actionBar.setIcon(null);
        }
    }

    try {
        ViewConfiguration config = ViewConfiguration.get(this);
        Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
        if(menuKeyField != null) {
            menuKeyField.setAccessible(true);
            menuKeyField.setBoolean(config, false);
        }
    } catch (Exception ex) {
        // Ignore
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    if (actionBar != null) {
        int padding = (getDisplayWidth() - actionBarTitle.getWidth())/2;

        MenuInflater inflater = getMenuInflater();
        if (this.getClass() == MenuActivity.class) {
            inflater.inflate(R.menu.activity_close_menu, menu);
        }
        else {
            inflater.inflate(R.menu.activity_open_menu, menu);
        }

        MenuItem item = menu.findItem(R.id.main_menu);
        Drawable icon = item.getIcon();
        icon.mutate().mutate().setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_IN);
        item.setIcon(icon);

        ImageButton imageButton;
        for (int i =0; i < toolbar.getChildCount(); i++) {
            if (toolbar.getChildAt(i).getClass() == ImageButton.class) {
                imageButton = (ImageButton) toolbar.getChildAt(i);
                padding -= imageButton.getWidth();
                break;
            }
        }

        actionBarTitle.setPadding(padding, 0, 0, 0);
    }

    return super.onCreateOptionsMenu(menu);
} ...

And my action_bar.xml is like this (if anyone is interested):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_gravity="center"
          android:orientation="horizontal">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@color/actionbar_text_color"
        android:textAllCaps="true"
        android:textSize="9pt"
        />

</LinearLayout>

EDIT: If you need to change the title to something else AFTER the activity is loaded (onCreateOptionsMenu has already been called), put another TextView in your action_bar.xml and use the following code to "pad" this new TextView, set text and show it:

protected void setSubTitle(CharSequence title) {

    if (!initActionBarTitle()) return;

    if (actionBarSubTitle != null) {
        if (title != null || title.length() > 0) {
            actionBarSubTitle.setText(title);
            setActionBarSubTitlePadding();
        }
    }
}

private void setActionBarSubTitlePadding() {
    if (actionBarSubTitlePaddingSet) return;
    ViewTreeObserver vto = layout.getViewTreeObserver();
    if(vto.isAlive()){
        vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int padding = (getDisplayWidth() - actionBarSubTitle.getWidth())/2;

                ImageButton imageButton;
                for (int i = 0; i < toolbar.getChildCount(); i++) {
                    if (toolbar.getChildAt(i).getClass() == ImageButton.class) {
                        imageButton = (ImageButton) toolbar.getChildAt(i);
                        padding -= imageButton.getWidth();
                        break;
                    }
                }

                actionBarSubTitle.setPadding(padding, 0, 0, 0);
                actionBarSubTitlePaddingSet = true;
                ViewTreeObserver obs = layout.getViewTreeObserver();
                obs.removeOnGlobalLayoutListener(this);
            }
        });
    }
}

protected void hideActionBarTitle() {

    if (!initActionBarTitle()) return;

    actionBarTitle.setVisibility(View.GONE);
    if (actionBarSubTitle != null) {
        actionBarSubTitle.setVisibility(View.VISIBLE);
    }
}

protected void showActionBarTitle() {

    if (!initActionBarTitle()) return;

    actionBarTitle.setVisibility(View.VISIBLE);
    if (actionBarSubTitle != null) {
        actionBarSubTitle.setVisibility(View.GONE);
    }
}

EDIT (25.08.2016): This does not work with appcompat 24.2.0 revision (August 2016), if your activity has a "back button". I filed a bug report (Issue 220899), but I do not know if it is of any use (doubt it will be fixed any time soon). Meanwhile the solution is to check if the child's class is equal to AppCompatImageButton.class and do the same, only increase the width by 30% (e.g. appCompatImageButton.getWidth()*1.3 before subtracting this value from the original padding):

padding -= appCompatImageButton.getWidth()*1.3;

In the mean time I threw in some padding/margin checks in there:

    Class<?> c;
    ImageButton imageButton;
    AppCompatImageButton appCompatImageButton;
    for (int i = 0; i < toolbar.getChildCount(); i++) {
        c = toolbar.getChildAt(i).getClass();
        if (c == AppCompatImageButton.class) {
            appCompatImageButton = (AppCompatImageButton) toolbar.getChildAt(i);
            padding -= appCompatImageButton.getWidth()*1.3;
            padding -= appCompatImageButton.getPaddingLeft();
            padding -= appCompatImageButton.getPaddingRight();
            if (appCompatImageButton.getLayoutParams().getClass() == LinearLayout.LayoutParams.class) {
                padding -= ((LinearLayout.LayoutParams) appCompatImageButton.getLayoutParams()).getMarginEnd();
                padding -= ((LinearLayout.LayoutParams) appCompatImageButton.getLayoutParams()).getMarginStart();
            }
            break;
        }
        else if (c == ImageButton.class) {
            imageButton = (ImageButton) toolbar.getChildAt(i);
            padding -= imageButton.getWidth();
            padding -= imageButton.getPaddingLeft();
            padding -= imageButton.getPaddingRight();
            if (imageButton.getLayoutParams().getClass() == LinearLayout.LayoutParams.class) {
                padding -= ((LinearLayout.LayoutParams) imageButton.getLayoutParams()).getMarginEnd();
                padding -= ((LinearLayout.LayoutParams) imageButton.getLayoutParams()).getMarginStart();
            }
            break;
        }
    }

The easier is add [0] - select first value of list with one element:

dfb = df[df['A']==5].index.values.astype(int)[0]
dfbb = df[df['A']==8].index.values.astype(int)[0]

dfb = int(df[df['A']==5].index[0])
dfbb = int(df[df['A']==8].index[0])

But if possible some values not match, error is raised, because first value not exist.

Solution is use next with iter for get default parameetr if values not matched:

dfb = next(iter(df[df['A']==5].index), 'no match')
print (dfb)
4

dfb = next(iter(df[df['A']==50].index), 'no match')
print (dfb)
no match

Then it seems need substract 1:

print (df.loc[dfb:dfbb-1,'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

Another solution with boolean indexing or query:

print (df[(df['A'] >= 5) & (df['A'] < 8)])
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

print (df.loc[(df['A'] >= 5) & (df['A'] < 8), 'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

print (df.query('A >= 5 and A < 8'))
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

Don't include the whole play services library but use the one that you need.Replace the line in your build.gradle:

compile 'com.google.android.gms:play-services:9.6.1'

with the appropriate one from Google Play Services APIs,like for example:

compile 'com.google.android.gms:play-services-gcm:9.6.1'
