you must clear the target file such as in jar and others In C: drive your folder at .m2 see the location where it install and delete the .jar file,Snaphot file and delete target files then clean the application you found it will be run

It will work when adding space between id and class identifier

Say your list has 100 elements and you want to pick 50 of them in a random way. Here are the steps to follow:

1. Import the libraries
2. Create the seed for random number generator, I have put it at 2
3. Prepare a list of numbers from which to pick up in a random way
4. Make the random choices from the numbers list

Code:

from random import seed
from random import choice

seed(2)
numbers = [i for i in range(100)]

print(numbers)

for _ in range(50):
    selection = choice(numbers)
    print(selection)

JPanel is almost always the wrong class to subclass. Why wouldn't you subclass JComponent?

There is a slight problem with ImageIcon in that the constructor blocks reading the image. Not really a problem when loading from the application jar, but maybe if you're potentially reading over a network connection. There's plenty of AWT-era examples of using MediaTracker, ImageObserver and friends, even in the JDK demos.

Here is a solution to get the country based on an international phone number without using the Google library.

Let me explain first why it is so difficult to figure out the country. The country code of few countries is 1 digit, 2, 3 or 4 digits. That would be simple enough. But the country code 1 is not just used for US, but also for Canada and some smaller places:

1339 USA
1340 Virgin Islands (Caribbean Islands)
1341 USA
1342 not used
1343 Canada

Digits 2..4 decide, if it is US or Canada or ... There is no easy way to figure out the country, like the first xxx are Canada, the rest US.

For my code, I defined a class which holds information for ever digit:

public class DigitInfo {
  public char Digit;
  public Country? Country;
  public DigitInfo?[]? Digits;
}

A first array holds the DigitInfos for the first digit in the number. The second digit is used as an index into DigitInfo.Digits. One travels down that Digits chain, until Digits is empty. If Country is defined (i.e. not null) that value gets returned, otherwise any Country defined earlier gets returned:

country code 1: byPhone[1].Country is US  
country code 1236: byPhone[1].Digits[2].Digits[3].Digits[6].Country is Canada  
country code 1235: byPhone[1].Digits[2].Digits[3].Digits[5].Country is null. Since   
                   byPhone[1].Country is US, also 1235 is US, because no other   
                   country was found in the later digits

Here is the method which returns the country based on the phone number:

/// <summary>
/// Returns the Country based on an international dialing code.
/// </summary>
public static Country? GetCountry(ReadOnlySpan<char> phoneNumber) {
  if (phoneNumber.Length==0) return null;

  var isFirstDigit = true;
  DigitInfo? digitInfo = null;
  Country? country = null;
  foreach (var digitChar in phoneNumber) {
    var digitIndex = digitChar - '0';
    if (isFirstDigit) {
      isFirstDigit = false;
      digitInfo = ByPhone[digitIndex];
    } else {
      if (digitInfo!.Digits is null) return country;

      digitInfo = digitInfo.Digits[digitIndex];
    }
    if (digitInfo is null) return country;

    country = digitInfo.Country??country;
  }
  return country;
}

The rest of the code (digitInfos for every country of the world, test code, ...) is too big to be posted here, but it can be found on Github: https://github.com/PeterHuberSg/WpfWindowsLib/blob/master/WpfWindowsLib/CountryCode.cs

The code is part of a WPF TextBox and the library contains also other controls for email addresses, etc. A more detailed description is on CodeProject: International Phone Number Validation Explained in Detail

If you have installed mongodb community server via homebrew, then you can do:

brew services list

This will list the current services as below:

Name              Status  User          Plist
mongodb-community started thehaystacker /Users/thehaystacker/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist

redis             stopped

Then you can restart mongodb by first stopping and restart:

brew services stop mongodb
brew services start mongodb

Here is a pure C# version that should work with all versions of .NET (including .NET Core, .NET 5, WPF, Winforms, etc.) and uses Windows Vista (and higher) IFileDialog interface with the FOS_PICKFOLDERS options so it has the nice folder picker Windows standard UI. I have also added WPF's Window type support but this is optional.

usage:

var dlg = new FolderPicker();
dlg.InputPath = @"c:\windows\system32";
if (dlg.ShowDialog() == true)
{
    MessageBox.Show(dlg.ResultPath);
}

code:

    using System;

result:

staticmethod objects apparently have a __func__ attribute storing the original raw function (makes sense that they had to). So this will work:

class Klass(object):

    @staticmethod  # use as decorator
    def stat_func():
        return 42

    _ANS = stat_func.__func__()  # call the staticmethod

    def method(self):
        ret = Klass.stat_func()
        return ret

As an aside, though I suspected that a staticmethod object had some sort of attribute storing the original function, I had no idea of the specifics. In the spirit of teaching someone to fish rather than giving them a fish, this is what I did to investigate and find that out (a C&P from my Python session):

>>> class Foo(object):
...     @staticmethod
...     def foo():
...         return 3
...     global z
...     z = foo

>>> z
<staticmethod object at 0x0000000002E40558>
>>> Foo.foo
<function foo at 0x0000000002E3CBA8>
>>> dir(z)
['__class__', '__delattr__', '__doc__', '__format__', '__func__', '__get__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
>>> z.__func__
<function foo at 0x0000000002E3CBA8>

Similar sorts of digging in an interactive session (dir is very helpful) can often solve these sorts of question very quickly.

With Spring 4, if your Controller is annotated with @RestController instead of @Controller, you don't need the @ResponseBody annotation.

The code would be

@RestController
public class FooController {

   @RequestMapping(value="/controller", method=GET)
   public String foo() {
      return "Response!";
   }

}

You can find the Javadoc for @RestController here

If you are using pandas and have lots of RAM (enough to read the whole file into memory) try using pd.read_csv with low_memory=False, e.g.:

import pandas as pd
data = pd.read_csv('file.csv', low_memory=False)

Here you are not fitting a normal distribution. Replacing sns.distplot(data) by sns.distplot(data, fit=norm, kde=False) should do the trick.

Here are the basics. I'm not sure that any of these count as "clear and simple" though.

I would query the information_schema - this has views that are much more readable than the underlying tables.

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

If you do not want to depend on throwing exception (which you probably should not) you can try this:

public static <T> T cast(Object o, Class<T> clazz) {
    return clazz.isInstance(o) ? clazz.cast(o) : null;
}

I faced this problem where the following query doesn't work as expected:

select 1 where getdate()<>null

we expect it to show 1 because getdate() doesn't return null. I guess it has something to do with SQL failing to cast null as datetime and skipping the row! of course we know we should use IS or IS NOT keywords to compare a variable with null but when comparing two parameters it gets hard to handle the null situation. as a solution you can create your own compare function like the following:

CREATE FUNCTION [dbo].[fnCompareDates]
(
    @DateTime1 datetime,
    @DateTime2 datetime
)
RETURNS bit
AS
BEGIN
    if (@DateTime1 is null and @DateTime2 is null) return 1;
    if (@DateTime1 = @DateTime2) return 1;
    return 0
END

and re writing the query like:

select 1 where dbo.fnCompareDates(getdate(),null)=0

Create a new folder, let's say local-maven-repo at the root of your Maven project.

Just add a local repo iside your <project> of your pom.xml:

<repositories>
    <repository>
        <id>local-maven-repo</id>
        <url>file:///${project.basedir}/local-maven-repo</url>
    </repository>
</repositories>

Then for each external jar you want to install, go at the root of your project and execute:

mvn deploy:deploy-file -DgroupId=[GROUP] -DartifactId=[ARTIFACT] -Dversion=[VERS] -Durl=file:./local-maven-repo/ -DrepositoryId=local-maven-repo -DupdateReleaseInfo=true -Dfile=[FILE_PATH]

(Copied from my reply on a similar question)

In interface Builder. Select the UIButton -> Attributes Inspector -> Edge=Title and modify the edge insets

the actual index is available as a property of the select element.

var sel = document.getElementById('CCards');
alert(sel.selectedIndex);

you can use the index to get to the selection option, where you can pull the text and value.

var opt = sel.options[sel.selectedIndex];
alert(opt.text);
alert(opt.value);

Lazy simple version for forgetfuls like me:

git rebase -i HEAD~3 or however many commits instead of 3.

Turn this

pick YourCommitMessageWhatever
pick YouGetThePoint
pick IdkManItsACommitMessage

into this

pick YourCommitMessageWhatever
s YouGetThePoint
s IdkManItsACommitMessage

and do some action where you hit esc then enter to save the changes. [1]

When the next screen comes up, get rid of those garbage # lines [2] and create a new commit message or something, and do the same escape enter action. [1]

Wowee, you have fewer commits. Or you just broke everything.

[1] - or whatever works with your git configuration. This is just a sequence that's efficient given my setup.

[2] - you'll see some stuff like # this is your n'th commit a few times, with your original commits right below these message. You want to remove these lines, and create a commit message to reflect the intentions of the n commits that you're combining into 1.

Match against a global regular expression:

anotherString = someString.replace(/cat/g, 'dog');

You can use attributes from the System.ComponentModel.DataAnnotations namespace to set validation rules. Refer Model Validation - By Mike Wasson for details.

Using the function above, you would do:

var myHash = new Hash('one',[1,10,5],'two', [2], 'three',[3,30,300]);

Of course, the following would also work:

var myHash = {}; // New object
myHash['one'] = [1,10,5];
myHash['two'] = [2];
myHash['three'] = [3, 30, 300];

since all objects in JavaScript are hash tables! It would, however, be harder to iterate over since using foreach(var item in object) would also get you all its functions, etc., but that might be enough depending on your needs.

Interesting info about MSCorlib:

• The .NET 2.0 assembly will reference and use the 2.0 mscorlib.The .NET 1.1 assembly will reference the 1.1 mscorlib but will use the 2.0 mscorlib at runtime (due to hard-coded version redirects in theruntime itself)
• In GAC there is only one version of mscorlib, you dont find 1.1 version on GAC even if you have 1.1 framework installed on your machine. It would be good if somebody can explain why MSCorlib 2.0 alone is in GAC whereas 1.x version live inside framework folder
• Is it possible to force a different runtime to be loaded by the application by making a config setting in your app / web.config? you won’t be able to choose the CLR version by settings in the ConfigurationFile – at that point, a CLR will already be running, and there can only be one per process. Immediately after the CLR is chosen the MSCorlib appropriate for that CLR is loaded.

You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

If CSS writing-mode: sideways-lr is what you prefer, and you happen to run into chromium/chrome based browser. You may try

With newer versions of bundler you can use the clean task:

$ bundle help clean
Usage:
    bundle clean

Options:
    [--dry-run=only print out changes, do not actually clean gems]
    [--force=forces clean even if --path is not set]
    [--no-color=Disable colorization in output]
    -V, [--verbose=Enable verbose output mode]

Cleans up unused gems in your bundler directory
$ bundle clean --dry-run --force
Would have removed actionmailer (3.1.12)
Would have removed actionmailer (3.2.0.rc2)
Would have removed actionpack (3.1.12)
Would have removed actionpack (3.2.0.rc2)
Would have removed activemodel (3.1.12)
...

edit:

This is not recommended if you're using a global gemset (i.e. - all of your projects keep their gems in the same place). There're few ways to keep each project's gems separate, though:

1. rvm gemsets (http://rvm.io/gemsets/basics)
2. bundle install with any of the following options: --deployment or --path=<path> (http://bundler.io/v1.3/man/bundle-install.1.html)

You can use HostingEnvironment.MapPath in any context where System.Web objects like HttpContext.Current are not available (e.g also from a static method).

var mappedPath = System.Web.Hosting.HostingEnvironment.MapPath("~/SomePath");

In your layout:

<Spinner 
        android:id="@+id/spinner"
        android:layout_width="fill_parent"

        android:drawSelectorOnTop="true"

We already have tons of options to get mean by group, adding one more from mosaic package.

mosaic::mean(speed~dive, data = df)
#dive1 dive2 
#0.579 0.440 

This returns a named numeric vector, if needed a dataframe we can wrap it in stack

stack(mosaic::mean(speed~dive, data = df))

#  values   ind
#1  0.579 dive1
#2  0.440 dive2

data

set.seed(123)
df <- data.frame(dive=factor(sample(c("dive1","dive2"),10,replace=TRUE)),
                 speed=runif(10))

In general, you need to use this feature when you don't want or don't have time to deal with a huge table. If this is your case, it's better to use --where option from mysqldump limiting resultset. For example, mysqldump -uuser -ppass database --where="1 = 1 LIMIT 500000" > resultset.sql.

MySQL (and subsequently SQLite) also support the REPLACE INTO syntax:

REPLACE INTO my_table (pk_id, col1) VALUES (5, '123');

This automatically identifies the primary key and finds a matching row to update, inserting a new one if none is found.

If you want to use optional arguments, but not named arguments, then this approach worked for me. I think this is much easier code to follow.

REM Get argument values.  If not specified, use default values.
IF "%1"=="" ( SET "DatabaseServer=localhost" ) ELSE ( SET "DatabaseServer=%1" )
IF "%2"=="" ( SET "DatabaseName=MyDatabase" ) ELSE ( SET "DatabaseName=%2" )

REM Do work
ECHO Database Server = %DatabaseServer%
ECHO Database Name   = %DatabaseName%

The sign in such cases (i.e when one or both operands are negative) is implementation-defined. The spec says in §5.6/4 (C++03),

The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined; otherwise (a/b)*b + a%b is equal to a. If both operands are nonnegative then the remainder is nonnegative; if not, the sign of the remainder is implementation-defined.

That is all the language has to say, as far as C++03 is concerned.

As stated in Apple Docs

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

I've managed to achieve what I wanted by using custom Build Configurations:

1. Go to your project / select your target / Build Settings / search for Custom Flags
2. For your chosen target set your custom flag using -D prefix (without white spaces), for both Debug and Release
3. Do above steps for every target you have

Here's how you check for target:

#if BANANA
    print("We have a banana")
#elseif MELONA
    print("Melona")
#else
    print("Kiwi")
#endif

Tested using Swift 2.2

If you look in the source code for $.fn.bind you will find that it's just an rewrite function for on:

function (types, data, fn) {
    return this.on(types, null, data, fn);
}

http://james.padolsey.com/jquery/#v=1.7.2&fn=$.fn.bind

might fail working with link_directories, then add each static library like following:

target_link_libraries(foo /path_to_static_library/libbar.a)

There is no str accessor for datetimes and you can't do dates.astype(str) either, you can call apply and use datetime.strftime:

In [73]:

dates = pd.to_datetime(pd.Series(['20010101', '20010331']), format = '%Y%m%d')
dates.apply(lambda x: x.strftime('%Y-%m-%d'))
Out[73]:
0    2001-01-01
1    2001-03-31
dtype: object

You can change the format of your date strings using whatever you like: strftime() and strptime() Behavior.

Update

As of version 0.17.0 you can do this using dt.strftime

dates.dt.strftime('%Y-%m-%d')

will now work

The simulator is just an application, and as such you can run it like any other application.

Xcode 7.x, 8.x, and 9.x

In Xcode 7.x, the iPhone Simulator has moved again: /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app.

Xcode 6.x

In Xcode 6.x, the iPhone Simulator has moved yet again, and now resides here: /Applications/Xcode.app/Contents/Developer/Applications/iOS Simulator.app.

Xcode 4.x, 5.x

In Xcode 4.x (through 4.5 on Mountain Lion) and Xcode 5.0.x on Mavericks, it lives here: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/

In my version of Xcode (4.5.2), I find it quite convenient to use the Open Developer Tool menu from either the dock icon or the Xcode menu:

Xcode 3.x

In Xcode 3.x, it lives here:

/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app

In some future version of Xcode, it will probably move again, it's a squirrelly little app.

jQuery Example

var $button = $('.increment-btn');
var $counter = $('.counter');

$button.click(function(){
  $counter.val( parseInt($counter.val()) + 1 ); // `parseInt` converts the `value` from a string to a number
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="text" value="1" class="counter"/>
<button type="button" class="increment-btn">Increment</button>

'Plain' JavaScript Example

var $button = document.querySelector('.increment-btn');
var $counter = document.querySelector('.counter');

$button.addEventListener('click', function(){
  $counter.value = parseInt($counter.value) + 1; // `parseInt` converts the `value` from a string to a number
}, false);

<input type="text" class="counter" value="1"/>
<button type="button" class="increment-btn">Increment</button>

You have to delete Your appname.dll file from your output folder. Cleanup Debug and Release folders. Rebuild and copy to output folder regenerated dll file.

If someone referring how to do the same feature (reading OTP using received SMS) on Xamarin Android like me :

1. Add this code to your AndroidManifest.xml file :

   <receiver android:name=".listener.BroadcastReveiverOTP">
   <intent-filter>
       <action android:name="android.provider.Telephony.SMS_RECEIVED" />
   </intent-filter>
   </receiver>
   <uses-permission android:name="android.permission.RECEIVE_SMS" />
   <uses-permission android:name="android.permission.BROADCAST_SMS" />
   <uses-permission android:name="android.permission.READ_SMS" />
   

2. Then create your BroadcastReveiver class in your Android Project.

   [BroadcastReceiver(Enabled = true)] [IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED" }, Priority = (int)IntentFilterPriority.HighPriority)] 
   public class BroadcastReveiverOTP : BroadcastReceiver {
           public static readonly string INTENT_ACTION = "android.provider.Telephony.SMS_RECEIVED";
   
           protected string message, address = string.Empty;
   
           public override void OnReceive(Context context, Intent intent)
           {
               if (intent.HasExtra("pdus"))
               {
                   var smsArray = (Java.Lang.Object[])intent.Extras.Get("pdus");
                   foreach (var item in smsArray)
                   {
                       var sms = SmsMessage.CreateFromPdu((byte[])item);
                       address = sms.OriginatingAddress;
                       if (address.Equals("NotifyDEMO"))
                       {
                           message = sms.MessageBody;
                           string[] pin = message.Split(' ');
                           if (!string.IsNullOrWhiteSpace(pin[0]))
                           { 
                                   // NOTE : Here I'm passing received OTP to Portable Project using MessagingCenter. So I can display the OTP in the relevant entry field.
                                   MessagingCenter.Send<object, string>(this,MessengerKeys.OnBroadcastReceived, pin[0]);
                           }
                           }
                   }
               }
           }
   }
   

3. Register this BroadcastReceiver class in your MainActivity class on Android Project:

   public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity {
   
           // Initialize your class
           private BroadcastReveiverOTP _receiver = new BroadcastReveiverOTP ();
   
           protected override void OnCreate(Bundle bundle) { 
                   base.OnCreate(bundle);
   
                   global::Xamarin.Forms.Forms.Init(this, bundle);
                   LoadApplication(new App());
   
                   // Register your receiver :  RegisterReceiver(_receiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
   
           }
   }
   

It's compiler dependent. That said, in general using " prioritizes headers in the current working directory over system headers. <> usually is used for system headers. From to the specification (Section 6.10.2):

A preprocessing directive of the form

  # include <h-char-sequence> new-line

searches a sequence of implementation-defined places for a header identified uniquely by the specified sequence between the < and > delimiters, and causes the replacement of that directive by the entire contents of the header. How the places are specified or the header identified is implementation-defined.

A preprocessing directive of the form

  # include "q-char-sequence" new-line

causes the replacement of that directive by the entire contents of the source file identified by the specified sequence between the " delimiters. The named source file is searched for in an implementation-defined manner. If this search is not supported, or if the search fails, the directive is reprocessed as if it read

  # include <h-char-sequence> new-line

with the identical contained sequence (including > characters, if any) from the original directive.

So on most compilers, using the "" first checks your local directory, and if it doesn't find a match then moves on to check the system paths. Using <> starts the search with system headers.

If you are only concerned with the constant True, a simple sum is fine. However, keep in mind that in Python other values evaluate as True as well. A more robust solution would be to use the bool builtin:

>>> l = [1, 2, True, False]
>>> sum(bool(x) for x in l)
3

UPDATE: Here's another similarly robust solution that has the advantage of being more transparent:

>>> sum(1 for x in l if x)
3

P.S. Python trivia: True could be true without being 1. Warning: do not try this at work!

>>> True = 2
>>> if True: print('true')
... 
true
>>> l = [True, True, False, True]
>>> sum(l)
6
>>> sum(bool(x) for x in l)
3
>>> sum(1 for x in l if x)
3

Much more evil:

True = False

You can simply check out a new branch, and then commit:

git checkout -b my_new_branch
git commit

Checking out the new branch will not discard your changes.

For Eclipse, modify project.properties like this: (your path please)

android.library.reference.1=../../../../workspace/appcompat_v7_22

And remove android-support-v4.jar file in your project's libs folder.

Inaccessible logs: Security

A new event source needs to have a unique name across all logs including Security (which needs admin privilege when it's being read).

So your app will need admin privilege to create a source. But that's probably an overkill.

I wrote this powershell script to create the event source at will. Save it as *.ps1 and run it with any privilege and it will elevate itself.

# CHECK OR RUN AS ADMIN

If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{   
    $arguments = "& '" + $myinvocation.mycommand.definition + "'"
    Start-Process powershell -Verb runAs -ArgumentList $arguments
    Break
}

# CHECK FOR EXISTENCE OR CREATE

$source = "My Service Event Source";
$logname = "Application";

if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
    [System.Diagnostics.EventLog]::CreateEventSource($source, $logname);
    Write-Host $source -f white -nonewline; Write-Host " successfully added." -f green;
}
else
{
    Write-Host $source -f white -nonewline; Write-Host " already exists.";
}

# DONE

Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');

If you can modify the string:

// Note: This function returns a pointer to a substring of the original string.
// If the given string was allocated dynamically, the caller must not overwrite
// that pointer with the returned value, since the original pointer must be
// deallocated using the same allocator with which it was allocated.  The return
// value must NOT be deallocated using free() etc.
char *trimwhitespace(char *str)
{
  char *end;

  // Trim leading space
  while(isspace((unsigned char)*str)) str++;

  if(*str == 0)  // All spaces?
    return str;

  // Trim trailing space
  end = str + strlen(str) - 1;
  while(end > str && isspace((unsigned char)*end)) end--;

  // Write new null terminator character
  end[1] = '\0';

  return str;
}

If you can't modify the string, then you can use basically the same method:

// Stores the trimmed input string into the given output buffer, which must be
// large enough to store the result.  If it is too small, the output is
// truncated.
size_t trimwhitespace(char *out, size_t len, const char *str)
{
  if(len == 0)
    return 0;

  const char *end;
  size_t out_size;

  // Trim leading space
  while(isspace((unsigned char)*str)) str++;

  if(*str == 0)  // All spaces?
  {
    *out = 0;
    return 1;
  }

  // Trim trailing space
  end = str + strlen(str) - 1;
  while(end > str && isspace((unsigned char)*end)) end--;
  end++;

  // Set output size to minimum of trimmed string length and buffer size minus 1
  out_size = (end - str) < len-1 ? (end - str) : len-1;

  // Copy trimmed string and add null terminator
  memcpy(out, str, out_size);
  out[out_size] = 0;

  return out_size;
}

This can be done without terminal, directly from IDE. Netbeans, for example.

1. Create a separate project with packages (Create Project - Java - Java Class Library).
2. Put your .java classes there.
3. Build this project.
4. Go to your project folder and find build and dist folders there.
5. Find .jar file in your dist folder.
6. Get your other project and add this .jar file to project libraries.
7. You can now reference classes from this library and its methods directly from code, if import is automatically done for you.

With this you can remove the column and store variable into another variable.

df = subset(data, select = -c(genome) )

        // cut the string down to the maximum number of characters
        output = output.Substring(0, characterLimit);
        // Check if the character right after the truncate point was a space
        // if not, we are in the middle of a word and need to remove the rest of it
        if (input.Substring(output.Length, 1) != " ")
        {
            int LastSpace = output.LastIndexOf(" ");

            // if we found a space then, cut back to that space
            if (LastSpace != -1)
            {
                output = output.Substring(0, LastSpace);
            }
        }
        // Finally, add the "..."
        output += "...";
    }
    return output;
}

You can bind a single click event to a page for all elements, no matter if they are already on that page or if they will arrive at some future time, like that:

$(document).bind('click', function (e) {
   var target = $(e.target);
   if (target.is('.myclass')) {
      e.preventDefault(); // if you want to cancel the event flow
      // do something
   } else if (target.is('.myotherclass')) {
      e.preventDefault();
      // do something else
   }
});

Been using it for a while. Works like a charm.

In jQuery 1.7 and later, it is recommended to use .on() in place of bind or any other event delegation method, but .bind() still works.

I have been witnessing this same issue in the last 2 weeks while working with Kafka and have been reading this Stackoverflow's post ever since.

After 2 weeks of analysis i have deduced that in my case this happens when trying to produce messages to a topic that doesn't exist.

The outcome in my case is that Kafka sends an error message back but creates, at the same time, the topic that did not exist before. So if I try to produce any message again to that topic after this event, the error will not appear anymore as the topic as been created.

PLEASE NOTE: It could be that my particular Kafka installation was configured to automatically create the topic when the same does not exist; that should explain why in my case I can see the issue only once for every topic after resetting the topics: your configuration might be different and in that case you would keep receiving the same error over and over.

I think this is the best way to run php script on html and htm pages:

AddType application/x-httpd-php5 .html .htm

Declare systemStatus in an outer scope and assign it in an onload handler.

systemStatus = null;

function onloadHandler(evt) {
    systemStatus = document.getElementById("....");
}

Or if you don't want the onload handler, put your script tag at the bottom of your HTML.

static void Main(string[] args)
        {
            string[] array1 = Directory.GetFiles(@"D:\");
            string[] array2 = System.IO.Directory.GetDirectories(@"D:\");
            Console.WriteLine("--- Files: ---");
            foreach (string name in array1)
            {
                Console.WriteLine(name);
            }
            foreach (string name in array2)
            {
                Console.WriteLine(name);
            }
                  Console.ReadLine();
        }

I also had to remove the SMSS before it would get past that step.

Did you check this line works perfectly & your string have value in it ?

string jsonString = sr.ReadToEnd();

if yes, try this code for last line:

ValueSet items = JsonConvert.DeserializeObject<ValueSet>(jsonString);

or if you have an array of json you can use list like this :

List<ValueSet> items = JsonConvert.DeserializeObject<List<ValueSet>>(jsonString);

good luck

Reflection.

using System.Reflection;

Vendor vendor = new Vendor();
object tag = vendor.Tag;

Type tagt = tag.GetType();
FieldInfo field = tagt.GetField("test");

string value = field.GetValue(tag);

Use the power wisely. Don't forget error checking. :)

In order to retrieve all the External Storages (whether they are SD cards or internal non-removable storages), you can use the following code:

final String state = Environment.getExternalStorageState();

if ( Environment.MEDIA_MOUNTED.equals(state) || Environment.MEDIA_MOUNTED_READ_ONLY.equals(state) ) {  // we can read the External Storage...           
    //Retrieve the primary External Storage:
    final File primaryExternalStorage = Environment.getExternalStorageDirectory();

    //Retrieve the External Storages root directory:
    final String externalStorageRootDir;
    if ( (externalStorageRootDir = primaryExternalStorage.getParent()) == null ) {  // no parent...
        Log.d(TAG, "External Storage: " + primaryExternalStorage + "\n");
    }
    else {
        final File externalStorageRoot = new File( externalStorageRootDir );
        final File[] files = externalStorageRoot.listFiles();

        for ( final File file : files ) {
            if ( file.isDirectory() && file.canRead() && (file.listFiles().length > 0) ) {  // it is a real directory (not a USB drive)...
                Log.d(TAG, "External Storage: " + file.getAbsolutePath() + "\n");
            }
        }
    }
}

Alternatively, you might use System.getenv("EXTERNAL_STORAGE") to retrieve the primary External Storage directory (e.g. "/storage/sdcard0") and System.getenv("SECONDARY_STORAGE") to retieve the list of all the secondary directories (e.g. "/storage/extSdCard:/storage/UsbDriveA:/storage/UsbDriveB"). Remember that, also in this case, you might want to filter the list of secondary directories in order to exclude the USB drives.

In any case, please note that using hard-coded paths is always a bad approach (expecially when every manufacturer may change it as pleased).

You may need read this https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

and below there is a Note.

Note Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.

Another way to accomplish this in a functional component, is to use useEffect and useFunction, like this:

import React, { useEffect } from 'react';

const App = () => {


  useEffect(() => {
    const handleEsc = (event) => {
       if (event.keyCode === 27) {
        console.log('Close')
      }
    };
    window.addEventListener('keydown', handleEsc);

    return () => {
      window.removeEventListener('keydown', handleEsc);
    };
  }, []);

  return(<p>Press ESC to console log "Close"</p>);
}

Instead of console.log, you can use useState to trigger something.

I forgot to select Microsoft Office Developer Tools for installation initially. In my case Visual Studio Professional 2013 and also 2015.

You can return an object of a Class in Java.

If you are returning more than 1 value that are related, then it makes sense to encapsulate them into a class and then return an object of that class.

If you want to return unrelated values, then you can use Java's built-in container classes like Map, List, Set etc. Check the java.util package's JavaDoc for more details.

I like this one depending of purpose

window.location.href.split("/")[2] == "localhost:17000" //always domain + port

You can apply it on any url-string

var url = "http://localhost:17000/sub1/sub2/mypage.html?q=12";
url.split("/")[2] == "localhost:17000"
url.split("/")[url.split("/").length-1] == "mypage.html?q=12"

Removing protocol, domain & path from url-string (relative path)

var arr = url.split("/");
if (arr.length>3)
   "/" + arr.splice(3, arr.length).join("/") == "/sub1/sub2/mypage.html?q=12"

The metacharacter \b is an anchor like the caret and the dollar sign. It matches at a position that is called a "word boundary". This match is zero-length.

There are three different positions that qualify as word boundaries:

• Before the first character in the string, if the first character is a word character.
• After the last character in the string, if the last character is a word character.
• Between two characters in the string, where one is a word character and the other is not a word character.

\B is the negated version of \b. \B matches at every position where \b does not. Effectively, \B matches at any position between two word characters as well as at any position between two non-word characters.

we can use javascript's FileReader() and it's readAsDataURL(fileContent) function to show local drive/folder file. Bind change event to image then call javascript's showpreview function. Try this -

<!doctype html>
<html>

<head>
    <meta charset='utf-8'>
    <meta name='viewport' content='width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;'>
    <meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
    <title></title>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

    <script type="text/javascript">
    function showpreview(e) {
        var reader = new FileReader();
        reader.onload = function (e) {
            $("#previewImage").attr("src", e.target.result);
        }
        //Imagepath.files[0] is blob type
        reader.readAsDataURL(e.files[0]);
    }
    </script>
</head>
<body >
    <div>
    <input type="file" name="fileupload" value="fileupload" id="fileupload" onchange='showpreview(this)'>
    </div>
    <div>
        &nbsp;
    </div>
    <div>
    <img width="50%" id="previewImage">
    </div>
</body>
</html>

Let me explain with an example and you would be able to see how it works.

Assuming you have the following table DIM_EQUIPMENT:

VIN         MAKE    MODEL   YEAR    COLOR
-----------------------------------------
1234ASDF    Ford    Taurus  2008    White
1234JKLM    Chevy   Truck   2005    Green
5678ASDF    Ford    Mustang 2008    Yellow

Run below SQL

SELECT VIN,
  MAKE,
  MODEL,
  YEAR,
  COLOR ,
  COUNT(*) OVER (PARTITION BY YEAR) AS COUNT2
FROM DIM_EQUIPMENT

The result would be as below

VIN         MAKE    MODEL   YEAR    COLOR     COUNT2
 ----------------------------------------------  
1234JKLM    Chevy   Truck   2005    Green     1
5678ASDF    Ford    Mustang 2008    Yellow    2
1234ASDF    Ford    Taurus  2008    White     2

See what happened.

You are able to count without Group By on YEAR and Match with ROW.

Another Interesting WAY to get same result if as below using WITH Clause, WITH works as in-line VIEW and can simplify the query especially complex ones, which is not the case here though since I am just trying to show usage

 WITH EQ AS
  ( SELECT YEAR AS YEAR2, COUNT(*) AS COUNT2 FROM DIM_EQUIPMENT GROUP BY YEAR
  )
SELECT VIN,
  MAKE,
  MODEL,
  YEAR,
  COLOR,
  COUNT2
FROM DIM_EQUIPMENT,
  EQ
WHERE EQ.YEAR2=DIM_EQUIPMENT.YEAR;

Although you need a pair of parentheses to print in Python 3, you no longer need a space after print, because it's a function. So that's only a single extra character.

If you still find typing a single pair of parentheses to be "unnecessarily time-consuming," you can do p = print and save a few characters that way. Because you can bind new references to functions but not to keywords, you can only do this print shortcut in Python 3.

Python 2:

>>> p = print
  File "<stdin>", line 1
    p = print
            ^
SyntaxError: invalid syntax

Python 3:

>>> p = print
>>> p('hello')
hello

It'll make your code less readable, but you'll save those few characters every time you print something.

The 'very insightful' article mentioned by @skrebel ( http://www.berenddeboer.net/rest/authentication.html ) discusses a convoluted but really broken method of authentication.

You may try to visit the page (which is supposed to be viewable only to authenticated user) http://www.berenddeboer.net/rest/site/authenticated.html without any login credentials.

(Sorry I can't comment on the answer.)

I would say REST and authentication simply do not mix. REST means stateless but 'authenticated' is a state. You cannot have them both at the same layer. If you are a RESTful advocate and frown upon states, then you have to go with HTTPS (i.e. leave the security issue to another layer).

When loading a resource make sure you notice the difference between:

getClass().getClassLoader().getResource("com/myorg/foo.jpg") //relative path

and

getClass().getResource("/com/myorg/foo.jpg")); //note the slash at the beginning

I guess, this confusion is causing most of problems when loading a resource.

Also, when you're loading an image it's easier to use getResourceAsStream():

BufferedImage image = ImageIO.read(getClass().getResourceAsStream("/com/myorg/foo.jpg"));

When you really have to load a (non-image) file from a JAR archive, you might try this:

File file = null;
String resource = "/com/myorg/foo.xml";
URL res = getClass().getResource(resource);
if (res.getProtocol().equals("jar")) {
    try {
        InputStream input = getClass().getResourceAsStream(resource);
        file = File.createTempFile("tempfile", ".tmp");
        OutputStream out = new FileOutputStream(file);
        int read;
        byte[] bytes = new byte[1024];

        while ((read = input.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }
        out.close();
        file.deleteOnExit();
    } catch (IOException ex) {
        Exceptions.printStackTrace(ex);
    }
} else {
    //this will probably work in your IDE, but not from a JAR
    file = new File(res.getFile());
}

if (file != null && !file.exists()) {
    throw new RuntimeException("Error: File " + file + " not found!");
}

I think what you want to do is this:

$(this).children('img').eq(0);

this will give you a jquery object containing the first img element, whereas

$(this).children('img')[0];

will give you the img element itself.

if you are adding multiple items to the list use this:

mAdapter.notifyItemRangeInserted(startPosition, itemcount);

This notify any registered observers that the currently reflected itemCount items starting at positionStart have been newly inserted. The item previously located at positionStart and beyond can now be found starting at position positinStart+itemCount

existing item in the dataset still considered up to date.

Replace '\n' with "\n". The escape sequence is not recognized when you use '.

See the manual.

For the question of how to write line endings, see the note here. Basically, different operating systems have different conventions for line endings. Windows uses "\r\n", unix based operating systems use "\n". You should stick to one convention (I'd chose "\n") and open your file in binary mode (fopen should get "wb", not "w").

Use the FOR command to echo a file line by line, and with the 'skip' option to miss a number of starting lines...

FOR /F "skip=1" %i in (file2.txt) do @echo %i

You could redirect the output of a batch file, containing something like...

FOR /F %%i in (file1.txt) do @echo %%i
FOR /F "skip=1" %%i in (file2.txt) do @echo %%i

Note the double % when a FOR variable is used within a batch file.

If you're on Windows use the following, select all, and copy from a Notepad window:

notepad ~/.ssh/id_rsa.pub  

If you're on OS X, use:

pbcopy < ~/.ssh/id_rsa.pub

Use the substring method of the String class :

String removeCurrency=amount.getText().toString().substring(3);

If you use the Bootstrap Collapse class sometimes {!! $text !!} is not worked for me but {{ html_entity_decode($text) }} is worked for me.

Try:

select right ('0'+convert(nvarchar(2), DATEPART(mm, getdate())),2 )

This problem could also be solved using a look-up table. This would require a small amount of static memory for both the encoder and decoder. This method will however be fast:

• Encoder table 512 bytes or 1024 bytes (twice the size if both upper and lower case is needed)
• Decoder table 256 bytes or 64 KiB (either a single char look-up or dual char look-up)

My solution uses 1024 bytes for the encoding table, and 256 bytes for decoding.

Note

During decoding IOException and IndexOutOfRangeException could occur (if a character has a too high value > 256). Methods for de/encoding streams or arrays should be implemented, this is just a proof of concept.

Update 2016-06-27: instead of using Observables, use either

• a BehaviorSubject, as recommended by @Abdulrahman in a comment, or
• a ReplaySubject, as recommended by @Jason Goemaat in a comment

A Subject is both an Observable (so we can subscribe() to it) and an Observer (so we can call next() on it to emit a new value). We exploit this feature. A Subject allows values to be multicast to many Observers. We don't exploit this feature (we only have one Observer).

BehaviorSubject is a variant of Subject. It has the notion of "the current value". We exploit this: whenever we create an ObservingComponent, it gets the current navigation item value from the BehaviorSubject automatically.

The code below and the plunker use BehaviorSubject.

ReplaySubject is another variant of Subject. If you want to wait until a value is actually produced, use ReplaySubject(1). Whereas a BehaviorSubject requires an initial value (which will be provided immediately), ReplaySubject does not. ReplaySubject will always provide the most recent value, but since it does not have a required initial value, the service can do some async operation before returning it's first value. It will still fire immediately on subsequent calls with the most recent value. If you just want one value, use first() on the subscription. You do not have to unsubscribe if you use first().

import {Injectable}      from '@angular/core'
import {BehaviorSubject} from 'rxjs/BehaviorSubject';

@Injectable()
export class NavService {
  // Observable navItem source
  private _navItemSource = new BehaviorSubject<number>(0);
  // Observable navItem stream
  navItem$ = this._navItemSource.asObservable();
  // service command
  changeNav(number) {
    this._navItemSource.next(number);
  }
}

import {Component}    from '@angular/core';
import {NavService}   from './nav.service';
import {Subscription} from 'rxjs/Subscription';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number;
  subscription:Subscription;
  constructor(private _navService:NavService) {}
  ngOnInit() {
    this.subscription = this._navService.navItem$
       .subscribe(item => this.item = item)
  }
  ngOnDestroy() {
    // prevent memory leak when component is destroyed
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>`
})
export class Navigation {
  item = 1;
  constructor(private _navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this._navService.changeNav(item);
  }
}

Plunker

Original answer that uses an Observable: (it requires more code and logic than using a BehaviorSubject, so I don't recommend it, but it may be instructive)

So, here's an implementation that uses an Observable instead of an EventEmitter. Unlike my EventEmitter implementation, this implementation also stores the currently selected navItem in the service, so that when an observing component is created, it can retrieve the current value via API call navItem(), and then be notified of changes via the navChange$ Observable.

import {Observable} from 'rxjs/Observable';
import 'rxjs/add/operator/share';
import {Observer} from 'rxjs/Observer';

export class NavService {
  private _navItem = 0;
  navChange$: Observable<number>;
  private _observer: Observer;
  constructor() {
    this.navChange$ = new Observable(observer =>
      this._observer = observer).share();
    // share() allows multiple subscribers
  }
  changeNav(number) {
    this._navItem = number;
    this._observer.next(number);
  }
  navItem() {
    return this._navItem;
  }
}

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number;
  subscription: any;
  constructor(private _navService:NavService) {}
  ngOnInit() {
    this.item = this._navService.navItem();
    this.subscription = this._navService.navChange$.subscribe(
      item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item:number;

See also the Component Interaction Cookbook example, which uses a Subject in addition to observables. Although the example is "parent and children communication," the same technique is applicable for unrelated components.

I will try to explain the basic difference using an example.

class A(object):
    x = 0

    def say_hi(self):
        pass

    @staticmethod
    def say_hi_static():
        pass

    @classmethod
    def say_hi_class(cls):
        pass

    def run_self(self):
        self.x += 1
        print self.x # outputs 1
        self.say_hi()
        self.say_hi_static()
        self.say_hi_class()

    @staticmethod
    def run_static():
        print A.x  # outputs 0
        # A.say_hi() #  wrong
        A.say_hi_static()
        A.say_hi_class()

    @classmethod
    def run_class(cls):
        print cls.x # outputs 0
        # cls.say_hi() #  wrong
        cls.say_hi_static()
        cls.say_hi_class()

1 - we can directly call static and classmethods without initializing

# A.run_self() #  wrong
A.run_static()
A.run_class()

2- Static method cannot call self method but can call other static and classmethod

3- Static method belong to class and will not use object at all.

4- Class method are not bound to an object but to a class.

Invalidate Caches and Restart did not work for me. I also updated all my Android Studio files with no success.

The solution I found was importing the android folder by clicking "Import project (Eclipse ADT, Gradle, etc.)" rather than clicking "Open an existing Android Studio Project" or dragging the folder onto the app icon.

Apparently the problem is caused because a module in the project has an *.iml file that does not contain external.system.id="GRADLE".

When you import the project (as opposed to opening it), the iml files are completely re-written, thus removing the error.

I found the info here: https://issuetracker.google.com/issues/37008041

For the people who want to override the Environment Variable of OS in Eclipse project, refer to @MAX answer too.

It's useful when you have release project end eclipse project at the same machine.

The release project can use the OS Environment Variable for test usage and eclipse project can override it for development usage.

For a pure javascript example, without using jQuery, check out this answer.

Steps:

1. Implements your object class to serializable

   public class Question implements Serializable`
   

2. Put this in your Source Activity

   ArrayList<Question> mQuestionList = new ArrayList<Question>;
   mQuestionsList = QuestionBank.getQuestions();  
   mQuestionList.add(new Question(ops1, choices1));
   
   Intent intent = new Intent(SourceActivity.this, TargetActivity.class);
   intent.putExtra("QuestionListExtra", mQuestionList);
   

3. Put this in your Target Activity

    ArrayList<Question> questions = new ArrayList<Question>();
    questions = (ArrayList<Questions>) getIntent().getSerializableExtra("QuestionListExtra");
   

Should anybody land with the same silly problem I had, make sure your component has the 'data' property spelled correctly. (eg. data, and not date)

<template>
    <span>{{name}}</span>
</template>

<script>
export default {
  name: "MyComponent",
  data() {
    return {
      name: ""
    };
  }
</script>

The documentation is your friend, NSString supports a call substringWithRange that can shorten the string that you have an return the shortened String. You cannot modify an instance of NSString it is immutable. If you have an NSMutableString is has a method called deleteCharactersInRange that can modify the string in place

...
NSRange r;
r.location = 0;
r.size = [mutable length]-1;
NSString* shorted = [stringValue substringWithRange:r];
...

Currently, it is not possible to prevent a user from writing decimal values in your input with HTML only. You have to use javascript.

Just to add on top of other answers:

Windows Users: You can give the PATH to JRE in eclipse.ini separated by '/' or '\'. It doesn't matter. Eclipse will pick it anyway. For example, in my windows system, either of the paths is fine (after -vm of course):

C:/Program Files/Java/jre1.8.0_181/bin or C:\Program Files\Java\jre1.8.0_181\bin

If you are on Public Network, Firewall will block all incoming connections by default. check your firewall settings or use private network to SSL

We can iterate loop like as C programming.

do 
      echo $i
done

You can move to desired activity on button click. just add this line.

android:onClick="sendMessage"

xml:

 <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="sendMessage"
        android:text="@string/button" />

In your main activity just add this method:

public void sendMessage(View view) {
    Intent intent = new Intent(FromActivity.this, ToActivity.class);
    startActivity(intent);
}

And the most important thing: don't forget to define your activity in manifest.xml

 <activity>
      android:name=".ToActivity"
      android:label="@string/app_name">          
 </activity>

By unpacking timetuple of datetime object, you should get what you want:

from datetime import datetime

n = datetime.now()
t = n.timetuple()
y, m, d, h, min, sec, wd, yd, i = t

If you are working with Flutter then this command would definitely work for you.

flutter doctor --android-licenses

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

You can export the data from MySQL to Excel by using this simple code.

  $rowData .= $value;
 }
 $setData .= trim($rowData)."\n";
}

Disclaimer: I'm the author of jgeXml.

jgexml has Node.js based utility xsd2json which does a transformation between an XML schema (XSD) and a JSON schema file.

As with other options, it's not a 1:1 conversion, and you may need to hand-edit the output to improve the JSON schema validation, but it has been used to represent a complex XML schema inside an OpenAPI (swagger) definition.

A sample of the purchaseorder.xsd given in another answer is rendered as:

"PurchaseOrderType": {
  "type": "object",
  "properties": {
    "shipTo": {
      "$ref": "#/definitions/USAddress"
    },
    "billTo": {
      "$ref": "#/definitions/USAddress"
    },
    "comment": {
      "$ref": "#/definitions/comment"
    },
    "items": {
      "$ref": "#/definitions/Items"
    },
    "orderDate": {
      "type": "string",
      "pattern": "^[0-9]{4}-[0-9]{2}-[0-9]{2}.*$"
    }
  },

I follow this way to append a new line in a .csv file:

pose_x = 1 
pose_y = 2

with open('path-to-your-csv-file.csv', mode='a') as file_:
    file_.write("{},{}".format(pose_x, pose_y))
    file_.write("\n")

I almost always end up defining n-Tuple classes when I code in Java. For instance:

public class Tuple2<T1,T2> {
  private T1 f1;
  private T2 f2;
  public Tuple2(T1 f1, T2 f2) {
    this.f1 = f1; this.f2 = f2;
  }
  public T1 getF1() {return f1;}
  public T2 getF2() {return f2;}
}

I know it's a bit ugly, but it works, and you just have to define your tuple types once. Tuples are something Java really lacks.

EDIT: David Hanak's example is more elegant, as it avoids defining getters and still keeps the object immutable.

In Windows git bash, I fixed it by restarting git bash

This is the simplest one.

#divid {

   bottom: 0;
   left: 0;
}

I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.

HEAD: the current commit your repo is on. Most of the time HEAD points to the latest commit in your current branch, but that doesn't have to be the case. HEAD really just means "what is my repo currently pointing at".

In the event that the commit HEAD refers to is not the tip of any branch, this is called a "detached head".

master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.

origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.

HEAD is an official notion in git. HEAD always has a well-defined meaning. master and origin are common names usually used in git, but they don't have to be.

There are many ways to set custom font family on field and I am using like that below.

To add fonts as resources, perform the following steps in the Android Studio:

1) Right-click the res folder and go to New > Android resource directory. The New Resource Directory window appears.

2) In the Resource type list, select font, and then click OK.

Note: The name of the resource directory must be font.

3) Add your font files in the font folder.

Add font in desired view in your xml file:

Note: But you required the following things for that:

1. Android Studio above to 3.0 canary.

2. Your Activity extends AppCompatActivity.

3. Update your Gradle file like that:

    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {        
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

buildtoolsVersion above to 26 and minimum targetSdkVersion required 26

4. Add dependencies in build.gradle file:

classpath 'com.android.tools.build:gradle:3.0.0-beta4'

5. gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

Your code should work, but I'm aware that answer doesn't help you. You can see a working example here (jsfiddle).

Jquery:

$(document).on('click','#test-element',function(){
    alert("You clicked the element with and ID of 'test-element'");
});

As someone already pointed out, you are using an ID instead of a class. If you have more that one element on the page with an ID, then jquery will return only the first element with that ID. There won't be any errors because that's how it works. If this is the problem, then you'll notice that the click event works for the first test-element but not for any that follow.

If this does not accurately describe the symptoms of the problem, then perhaps your selector is wrong. Your update leads me to believe this is the case because of inspecting an element then clicking the page again and triggering the click. What could be causing this is if you put the event listener on the actual document instead of test-element. If so, when you click off the document and back on (like from the developer window back to the document) the event will trigger. If this is the case, you'll also notice the click event is triggered if you click between two different tabs (because they are two different documents and therefore you are clicking the document.

If neither of these are the answer, posting HTML will go a long way toward figuring it out.

The "wipe user data" option finally solved my problem. just wipe user data every time you start the emulator. This always works for me! I use windows 8 x64 , eclipse

Use distinct-colors.

Written in javascript.

It generates a palette of visually distinct colors.

distinct-colors is highly configurable:

• Choose how many colors are in the palette
• Restrict the hue to a specific range
• Restrict the chroma (saturation) to a specific range
• Restrict the lightness to a specific range
• Configure general quality of the palette

it is due to expired of debug certificate simply delete the debug.keystore located at

C:\Users\.android\

after that build your project the build tools will regenerate a new key and it will work fine. here is a reference:

https://developer.android.com/studio/publish/app-signing

This can be done in following five steps:

This gem does these things for you automatically even the installation of required tools

1. convert apk file to zip
2. unzip the file
3. extract classes.dex from it
4. use dex to jar to convert classes.dex into jar file
5. use jadx gui to open the jar file as java source code

Note that sort() operates on the array in place, so you only need to call

sort($a);
doSomething($a);

This will not work;

$a = sort($a);
doSomething($a);

I believe you're looking for:

That is a serverside comment and will not be delivered to the client ... but it's not optional. If you need this to be programmable, then you'll want this answer :-)

What did the trick for me was to change the target machine from “ANY CPU” to “x64” or maybe in your case “x86” depending in your target machine’s architecture. I would try this first before moving into a more complex solution which indicates a more complex problem.

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

There answers above are correct. Although I would prefer to create a helper to wrap up the notification's observers.

The benefit:

1. You don't have to repeat each time you handle the keyboard behaviors.
2. You can extend other notification by implement other enum value
3. It's useful when you have to deal with keyboard in several controllers.

Sample code:

extension KeyboardHelper {
    enum Animation {
        case keyboardWillShow
        case keyboardWillHide
    }

    typealias HandleBlock = (_ animation: Animation, _ keyboardFrame: CGRect, _ duration: TimeInterval) -> Void
}

final class KeyboardHelper {
    private let handleBlock: HandleBlock

    init(handleBlock: @escaping HandleBlock) {
        self.handleBlock = handleBlock
        setupNotification()
    }

    deinit {
        NotificationCenter.default.removeObserver(self)
    }

    private func setupNotification() {
        _ = NotificationCenter.default
            .addObserver(forName: UIResponder.keyboardWillShowNotification, object: nil, queue: .main) { [weak self] notification in
                self?.handle(animation: .keyboardWillShow, notification: notification)
            }

        _ = NotificationCenter.default
            .addObserver(forName: UIResponder.keyboardWillHideNotification, object: nil, queue: .main) { [weak self] notification in
                self?.handle(animation: .keyboardWillHide, notification: notification)
            }
    }

    private func handle(animation: Animation, notification: Notification) {
        guard let userInfo = notification.userInfo,
            let keyboardFrame = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue,
            let duration = userInfo[UIResponder.keyboardAnimationDurationUserInfoKey] as? Double
        else { return }

        handleBlock(animation, keyboardFrame, duration)
    }
}

How to use:

private var keyboardHelper: KeyboardHelper?
...

override func viewDidLoad() {
   ...
   keyboardHelper = KeyboardHelper { [unowned self] animation, keyboardFrame, duration in
        switch animation {
        case .keyboardWillShow:
            print("keyboard will show")
        case .keyboardWillHide:
            print("keyboard will hide")
        }
    }

}

Add_ supplier is name of the form

private void add_supplier_Load(object sender, EventArgs e)

}

I justed faced very similar problem... BUT RegExp_Count couldn't resolved it. How many times string '16,124,3,3,1,0,' contains ',3,'? As we see 2 times, but RegExp_Count returns just 1. Same thing is with ''bbaaaacc' and when looking in it 'aa' - should be 3 times and RegExp_Count returns just 2.

select REGEXP_COUNT('336,14,3,3,11,0,' , ',3,') from dual;
select REGEXP_COUNT('bbaaaacc' , 'aa') from dual;

I lost some time to research solution on web. Couldn't' find... so i wrote my own function that returns TRUE number of occurance. Hope it will be usefull.

CREATE OR REPLACE FUNCTION EXPRESSION_COUNT( pEXPRESSION VARCHAR2, pPHRASE VARCHAR2 ) RETURN NUMBER AS
  vRET NUMBER := 0;
  vPHRASE_LENGTH NUMBER := 0;
  vCOUNTER NUMBER := 0;
  vEXPRESSION VARCHAR2(4000);
  vTEMP VARCHAR2(4000);
BEGIN
  vEXPRESSION := pEXPRESSION;
  vPHRASE_LENGTH := LENGTH( pPHRASE );
  LOOP
    vCOUNTER := vCOUNTER + 1;
    vTEMP := SUBSTR( vEXPRESSION, 1, vPHRASE_LENGTH);
    IF (vTEMP = pPHRASE) THEN        
        vRET := vRET + 1;
    END IF;
    vEXPRESSION := SUBSTR( vEXPRESSION, 2, LENGTH( vEXPRESSION ) - 1);
  EXIT WHEN ( LENGTH( vEXPRESSION ) = 0 ) OR (vEXPRESSION IS NULL);
  END LOOP;
  RETURN vRET;
END;

$modifyUrl = parse_url($url);

Use RGB values combined with opacity to get the transparency that you wish.

For instance,

<div style=" background: rgb(255, 0, 0) ; opacity: 0.2;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.4;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.6;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.8;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 1;">&nbsp;</div>

Similarly, with actual values without opacity, will give the below.

<div style=" background: rgb(243, 191, 189) ; ">&nbsp;</div>
<div style=" background: rgb(246, 143, 142) ; ">&nbsp;</div>
<div style=" background: rgb(249, 95 , 94)  ; ">&nbsp;</div>
<div style=" background: rgb(252, 47, 47)   ; ">&nbsp;</div>
<div style=" background: rgb(255, 0, 0)     ; ">&nbsp;</div>

You can have a look at this WORKING EXAMPLE.

Now, if we specifically target your issue, here is the WORKING DEMO SPECIFIC TO YOUR ISSUE.

The HTML

<div class="social">
    <img src="http://www.google.co.in/images/srpr/logo4w.png" border="0" />
</div>

The CSS:

social img{

}
.social img:hover {
    opacity:1;
    background-color:black;
    cursor:pointer;
    background: rgb(255, 0, 0) ; opacity: 0.5;
}

Hope this helps Now.

One little thing, might add clarity to override the default value for seconds

>>> b = a + datetime.timedelta(seconds=3000)
>>> b
datetime.datetime(1, 1, 1, 12, 24, 59)

var matches = [];
$(".className:checked").each(function() {
    matches.push(this.value);
});

Try with deleting pod it will try to pull image again.

kubectl delete pod <pod_name> -n <namespace_name>

Exit will exit PowerShell too. If you wish to "break" out of just the current function or script - use Break :)

If ($Breakout -eq $true)
{
     Write-Host "Break Out!"
     Break
}
ElseIf ($Breakout -eq $false)
{
     Write-Host "No Breakout for you!"
}
Else
{
    Write-Host "Breakout wasn't defined..."
}

Create the SqlParamObject which would give you control to access methods on the parameters

:

SqlParameter param = new SqlParameter();

SET the Name for your paramter (it should b same as you would have declared a variable to hold the value in your DataBase)

: param.ParameterName = "@yourParamterName";

Clear the value holder to hold you output data

: param.Value = 0;

Set the Direction of your Choice (In your case it should be Output)

: param.Direction = System.Data.ParameterDirection.Output;

As I am explaining later, I would always favor the TryParse and TryParseExact methods. Because they are a bit bulky to use, I have written an extension method which makes parsing much easier:

var    dtStr = "2011-03-21 13:26";
DateTime? dt = dtStr.ToDate("yyyy-MM-dd HH:mm");

Or more simply, if you want to use the date patterns of your current culture implicitly, you can use it like:

 DateTime? dt = dtStr.ToDate();

In that case no specific pattern need to be specified.

Unlike Parse, ParseExact etc. it does not throw an exception, and allows you to check via

if (dt.HasValue) { // continue processing } else { // do error handling }

whether the conversion was successful (in this case dt has a value you can access via dt.Value) or not (in this case, it is null).

That even allows to use elegant shortcuts like the "Elvis"-operator ?., for example:

int? year = dtStr?.ToDate("yyyy-MM-dd HH:mm")?.Year;

Here you can also use year.HasValue to check if the conversion succeeded, and if it did not succeed then year will contain null, otherwise the year portion of the date. There is no exception thrown if the conversion failed.

Solution:  The   .ToDate()   extension method

Try it in .NetFiddle

public static class Extensions
{
    /// <summary>
    /// Extension method parsing a date string to a DateTime? <para/>
    /// </summary>
    /// <param name="dateTimeStr">The date string to parse</param>
    /// <param name="dateFmt">dateFmt is optional and allows to pass 
    /// a parsing pattern array or one or more patterns passed 
    /// as string parameters</param>
    /// <returns>Parsed DateTime or null</returns>
    public static DateTime? ToDate(this string dateTimeStr, params string[] dateFmt)
    {
      // example: var dt = "2011-03-21 13:26".ToDate(new string[]{"yyyy-MM-dd HH:mm", 
      //                                                  "M/d/yyyy h:mm:ss tt"});
      // or simpler: 
      // var dt = "2011-03-21 13:26".ToDate("yyyy-MM-dd HH:mm", "M/d/yyyy h:mm:ss tt");
      const DateTimeStyles style = DateTimeStyles.AllowWhiteSpaces;
      if (dateFmt == null)
      {
        var dateInfo = System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat;
        dateFmt=dateInfo.GetAllDateTimePatterns();
      }
      var result = DateTime.TryParseExact(dateTimeStr, dateFmt, CultureInfo.InvariantCulture,
                   style, out var dt) ? dt : null as DateTime?;
      return result;
    }
}

Some information about the code

You might wonder, why I have used InvariantCulture calling TryParseExact: This is to force the function to treat format patterns always the same way (otherwise for example "." could be interpreted as decimal separator in English while it is a group separator or a date separator in German). Recall we have already queried the culture based format strings a few lines before so that is okay here.

Update: .ToDate() (without parameters) now defaults to all common date/time patterns of the thread's current culture.
Note that we need the result and dt together, because TryParseExact does not allow to use DateTime?, which we intend to return. In C# Version 7 you could simplify the ToDate function a bit as follows:

 // in C#7 only: "DateTime dt;" - no longer required, declare implicitly
 if (DateTime.TryParseExact(dateTimeStr, dateFmt,
     CultureInfo.InvariantCulture, style, out var dt)) result = dt;

or, if you like it even shorter:

 // in C#7 only: Declaration of result as a "one-liner" ;-)
 var result = DateTime.TryParseExact(dateTimeStr, dateFmt, CultureInfo.InvariantCulture,
              style, out var dt) ? dt : null as DateTime?;

in which case you don't need the two declarations DateTime? result = null; and DateTime dt; at all - you can do it in one line of code. (It would also be allowed to write out DateTime dt instead of out var dt if you prefer that).

The old style of C# would have required it the following way (I removed that from the code above):

  // DateTime? result = null;
  // DateTime dt;
  // if (DateTime.TryParseExact(dateTimeStr, dateFmt,
  //    CultureInfo.InvariantCulture, style, out dt)) result = dt;

I have simplified the code further by using the params keyword: Now you don't need the 2^nd overloaded method any more.

Example of usage

var dtStr="2011-03-21 13:26";    
var dt=dtStr.ToDate("yyyy-MM-dd HH:mm");
if (dt.HasValue)
{
    Console.WriteLine("Successful!");
    // ... dt.Value now contains the converted DateTime ...
}
else
{
    Console.WriteLine("Invalid date format!");
}

As you can see, this example just queries dt.HasValue to see if the conversion was successful or not. As an extra bonus, TryParseExact allows to specify strict DateTimeStyles so you know exactly whether a proper date/time string has been passed or not.

More Examples of usage

The overloaded function allows you to pass an array of valid formats used for parsing/converting dates as shown here as well (TryParseExact directly supports this), e.g.

string[] dateFmt = {"M/d/yyyy h:mm:ss tt", "M/d/yyyy h:mm tt", 
                     "MM/dd/yyyy hh:mm:ss", "M/d/yyyy h:mm:ss", 
                     "M/d/yyyy hh:mm tt", "M/d/yyyy hh tt", 
                     "M/d/yyyy h:mm", "M/d/yyyy h:mm", 
                     "MM/dd/yyyy hh:mm", "M/dd/yyyy hh:mm"};
var dtStr="5/1/2009 6:32 PM"; 
var dt=dtStr.ToDate(dateFmt);

If you have only a few template patterns, you can also write:

var dateStr = "2011-03-21 13:26";
var dt = dateStr.ToDate("yyyy-MM-dd HH:mm", "M/d/yyyy h:mm:ss tt");

Advanced examples

You can use the ?? operator to default to a fail-safe format, e.g.

var dtStr = "2017-12-30 11:37:00";
var dt = (dtStr.ToDate()) ?? dtStr.ToDate("yyyy-MM-dd HH:mm:ss");

In this case, the .ToDate() would use common local culture date formats, and if all these failed, it would try to use the ISO standard format "yyyy-MM-dd HH:mm:ss" as a fallback. This way, the extension function allows to "chain" different fallback formats easily.

You can even use the extension in LINQ, try this out (it's in the .NetFiddle above):

var strDateArray = new[] { "15-01-2019", "15.01.2021" };
var patterns=new[] { "dd-MM-yyyy", "dd.MM.yyyy" };
var dtRange = strDateArray.Select(s => s.ToDate(patterns));
dtRange.Dump(); 

which will convert the dates in the array on the fly by using the patterns and dump them to the console.

Some background about TryParseExact

Finally, Here are some comments about the background (i.e. the reason why I have written it this way):

I am preferring TryParseExact in this extension method, because you avoid exception handling - you can read in Eric Lippert's article about exceptions why you should use TryParse rather than Parse, I quote him about that topic:²⁾

This unfortunate design decision¹⁾ [annotation: to let the Parse method throw an exception] was so vexing that of course the frameworks team implemented TryParse shortly thereafter which does the right thing.

It does, but TryParse and TryParseExact both are still a lot less than comfortable to use: They force you to use an uninitialized variable as an out parameter which must not be nullable and while you're converting you need to evaluate the boolean return value - either you have to use an ifstatement immediately or you have to store the return value in an additional boolean variable so you're able to do the check later. And you can't just use the target variable without knowing if the conversion was successful or not.

In most cases you just want to know whether the conversion was successful or not (and of course the value if it was successful), so a nullable target variable which keeps all the information would be desirable and much more elegant - because the entire information is just stored in one place: That is consistent and easy to use, and much less error-prone.

The extension method I have written does exactly that (it also shows you what kind of code you would have to write every time if you're not going to use it).

I believe the benefit of .ToDate(strDateFormat) is that it looks simple and clean - as simple as the original DateTime.Parse was supposed to be - but with the ability to check if the conversion was successful, and without throwing exceptions.

¹⁾ What is meant here is that exception handling (i.e. a try { ... } catch(Exception ex) { ...} block) - which is necessary when you're using Parse because it will throw an exception if an invalid string is parsed - is not only unnecessary in this case but also annoying, and complicating your code. TryParse avoids all this as the code sample I've provided is showing.

²⁾ Eric Lippert is a famous StackOverflow fellow and was working at Microsoft as principal developer on the C# compiler team for a couple of years.

For me this is the only combination worked!

"terminal.integrated.shell.windows": "C:\\Program Files\\Git\\git-cmd.exe",
"terminal.integrated.shellArgs.windows": [
  "--command=usr/bin/bash.exe",
  "-l",
  "-i"
]

With git-bash.exe as the ...shell.windows, every time the bash was opening outside VS!!

Thank God it worked finally!! Else, I was planning to wipe out VS completely and reinstall it (making me to reinstall all my extensions and redo my customizations!)

Let's say we have a table with a column time and you want the last 5 entries, but you want them returned to you in asc order, not desc, this is how you do it:

select * from ( select * from `table` order by `time` desc limit 5 ) t order by `time` asc

Adding margin to align images:

Since we wanted the image to be left-aligned, we added:

img {
  margin-right: auto;
}

Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.

Good Luck...

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

If you don't want or can't install postgres again, you can install the server from the binary zip like this post explains it.

Take This as an alternate to startActivityforResult.But keep in mind that for such cases this approach can be expensive in terms of performance but in some cases you might need to use.

In Activity2,

@Override
public void onBackPressed() {
String data = mEditText.getText();
SharedPreferences sp = getSharedPreferences("LoginInfos", 0);
Editor editor = sp.edit();
editor.putString("email",data);
editor.commit();
}

In Activity1,

 @Override
public void onResume() {
SharedPreferences sp = getSharedPreferences("LoginInfos", 0);
String  dataFromOtherAct= sp.getString("email", "no email");
} 

Put this in C2 and copy down

=IF(ISNA(VLOOKUP(A2,$B$2:$B$65535,1,FALSE)),"not in B","")

Then if the value in A isn't in B the cell in column C will say "not in B".

if(strtotime($db_date) > time()) {
  echo $db_date;
} else {
  echo 'go ahead';
}

Just one line will be OK.

I have a Samsung Galaxy Tab 2 7.0 with Android 4.1.1. Apparently it does NOT sync to ntp. I loaded an app that says my tablet is 20 seconds off of ntp, but it can't set it unless I root the device.

If I use Firefox then screen.width and screen.height works fine but in IE and Chrome they don't work properly instead it opens with the minimum size.

And yes I tried giving too large numbers too like 10000 for both height and width but not exactly the maximized effect.

The array declaration should be:

Car[] garage = new Car[100];

You can also just assign directly:

garage[1] = new Car("Blue");

Your second way is correct.

def foo(opts: dict = {}):
    pass

print(foo.__annotations__)

this outputs

{'opts': <class 'dict'>}

It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.

I strongly advise against using mutable keyword arguments. More information here.

I'm late to the party but I found some useful instructions in github help page and I wanted to share them here.

Sometimes, Git can't make your change to a remote repository without losing commits. When this happens, your push is refused.

If another person has pushed to the same branch as you, Git won't be able to push your changes:

$ git push origin master
To https://github.com/USERNAME/REPOSITORY.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/USERNAME/REPOSITORY.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again.  See the
'Note about fast-forwards' section of 'git push --help' for details.

You can fix this by fetching and merging the changes made on the remote branch with the changes that you have made locally:

$ git fetch origin
# Fetches updates made to an online repository
$ git merge origin YOUR_BRANCH_NAME
# Merges updates made online with your local work

Or, you can simply use git pull to perform both commands at once:

$ git pull origin YOUR_BRANCH_NAME
# Grabs online updates and merges them with your local work

While Niemeyer's answer is a more correct answer to the question, you could also do the following:

<div>
  <input data-bind="value: VMA.name" />
</div>

<div>
  <input data-bind="value: VMB.name" />
</div>

<script type="text/javascript">
  var viewModels = {
     VMA: {name: ko.observable("Bob")},
     VMB: {name: ko.observable("Ted")}
  };

  ko.applyBindings(viewModels);
</script>

This means you don't have to specify the DOM element, and you can even bind multiple models to the same element, like this:

<div>
  <input data-bind="value: VMA.name() + ' and ' + VMB.name()" />
</div>

With the dplyr version >= 1.0.0, we can also use summarise to apply function on multiple columns with across

If you have an older version of memcached and need a script to wrap memcached as a service, here it is: Memcached Service Script

Here is a quite clean way to end edition with the Return Key or a touch in the background.

In Interface builder, embed your fields in a view of class UIFormView

What does this class :

• Automatically attach itself as fields delegate ( Either awaked from nib, or added manually )
• Keep a reference on the current edited field
• Dismiss the keyboard on return or touch in the background

Here is the code :

Interface

#import <UIKit/UIKit.h>

@interface UIFormView : UIView<UITextFieldDelegate>

-(BOOL)textFieldValueIsValid:(UITextField*)textField;
-(void)endEdit;

@end

Implementation

#import "UIFormView.h"

@implementation UIFormView
{
    UITextField* currentEditingTextField;
}

// Automatically register fields

-(void)addSubview:(UIView *)view
{
    [super addSubview:view];
    if ([view isKindOfClass:[UITextField class]]) {
        if ( ![(UITextField*)view delegate] ) [(UITextField*)view setDelegate:self];
    }
}

// UITextField Protocol

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    currentEditingTextField = textField;
}

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    currentEditingTextField = NULL;
}

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self endEdit];
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    if ([self textFieldValueIsValid:textField]) {
        [self endEdit];
        return YES;
    } else {
        return NO;
    }
}

// Own functions

-(void)endEdit
{
    if (currentEditingTextField) {
        [currentEditingTextField endEditing:YES];
        currentEditingTextField = NULL;
    }
}


// Override this in your subclass to handle eventual values that may prevent validation.

-(BOOL)textFieldValueIsValid:(UITextField*)textField
{
    return YES;
}

@end

• By subclassing the form and overriding the textFieldValueIsValid: method, you can avoid end of edition if the value is not correct for the given field.

• If a field has a delegate set in Interface Builder, then the form does not change it. I don't see many reasons to set a different delegate to a particular field, but why not…

There is many ways to improve this form view class - Attach a delegate, do some layout, handle when the keyboards covers a field ( using the currentEditingTextField frame ), automatically start edition for the next field, ...

I personally keep it in my framework, and always subclass it to add features, it is quite often useful "as-is".

I hope it will helps. Cheers all

Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.

You can check this by running in Windows PowerShell:

> Get-Service ssh-agent

And then check the output of status is not running.

Status   Name               DisplayName
------   ----               -----------
Stopped  ssh-agent          OpenSSH Authentication Agent

Then check that the service has been disabled by running

> Get-Service ssh-agent | Select StartType

StartType
---------
Disabled

I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:

 > Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Alternatively, you can set it through the GUI if you prefer.

For military time formatting,

select TO_CHAR(SYSDATE, 'yyyy-mm-dd hh24:mm:ss') from DUAL

--2018-07-10 15:07:15

If you want your date to round DOWN to Month, Day, Hour, Minute, you can try

SELECT TO_CHAR( SYSDATE, 'yyyy-mm-dd hh24:mi:ss') "full-date" --2018-07-11 10:40:26
, TO_CHAR( TRUNC(SYSDATE, 'year'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-year"-- 2018-01-01 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'month'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-month" -- 2018-07-01 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'day'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-Sunday" -- 2018-07-08 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'dd'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-day" -- 2018-07-11 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'hh'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-hour" -- 2018-07-11 10:00:00
, TO_CHAR( TRUNC(SYSDATE, 'mi'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-minute" -- 2018-07-11 10:40:00
from DUAL

Null object pattern can be used as a solution for this problem. For that, the class of the someObject should be modified.

public abstract class SomeObject {
   public abstract boolean isNil();
}

public class NullObject extends SomeObject {
   @Override
   public boolean isNil() {
      return true;
   }
}
public class RealObject extends SomeObject {
   @Override
   public boolean isNil() {
      return false;
   }
}

Now istead of checking,

 if (someobject != null) {
    someobject.doCalc();
}

We can use,

if (!someObject.isNil()) {
   someobject.doCalc();
}

As a completion to Gustavo Bezerra's answer:

If you want each histogram to be normalized (normed for mpl<=2.1 and density for mpl>=3.1) you cannot just use normed/density=True, you need to set the weights for each value instead:

import numpy as np
import matplotlib.pyplot as plt

x = np.random.normal(1, 2, 5000)
y = np.random.normal(-1, 3, 2000)
x_w = np.empty(x.shape)
x_w.fill(1/x.shape[0])
y_w = np.empty(y.shape)
y_w.fill(1/y.shape[0])
bins = np.linspace(-10, 10, 30)

plt.hist([x, y], bins, weights=[x_w, y_w], label=['x', 'y'])
plt.legend(loc='upper right')
plt.show()

As a comparison, the exact same x and y vectors with default weights and density=True:

function UpdateClick(btn) {

    for (i = 0; i < Page_Validators.length; i++) {

        ValidatorValidate(Page_Validators[i]);

        if (Page_Validators[i].isvalid == false)

            return false;
    }

    btn.disabled = 'false';

    btn.value = 'Please Wait...';

    return true;
}

I'd like to emphasize that order of arguments is important.

Font awesome is just a font so you can use the font size attribute in your CSS to change the size of the icon.

So you can just add a class to the icon like this:

.big-icon {
    font-size: 32px;
}

You Can try This To Run Command Then cmd Exits

Process.Start("cmd", "/c YourCode")

You Can try This To Run The Command And Let cmd Wait For More Commands

Process.Start("cmd", "/k YourCode")

Try with

ToString("#,##0.00")

From MSDN

*The "0" custom format specifier serves as a zero-placeholder symbol. If the value that is being formatted has a digit in the position where the zero appears in the format string, that digit is copied to the result string; otherwise, a zero appears in the result string. The position of the leftmost zero before the decimal point and the rightmost zero after the decimal point determines the range of digits that are always present in the result string.

The "00" specifier causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatting 34.5 with "00" would result in the value 35.*

The solution from this thread solved my problem:

Not sure if this will help anyone, but if you are using angular-cli, I fixed this by removing the CSS reference from my index.html and adding it to the angular-cli.json file under the "style" portion. After restarting my webserver I no longer had that issue.

Neither. You set the isolation level to READ UNCOMMITTED which is always better than giving individual lock hints. Or, better still, if you care about details like consistency, use snapshot isolation.

In RedBeanPHP 2.0 there is a mass-export function which turns an entire collection of beans into arrays. This works with the JSON encoder..

json_encode( R::exportAll( $beans ) );

$timeparts = explode(" ",microtime());
$currenttime = bcadd(($timeparts[0]*1000),bcmul($timeparts[1],1000));
echo $currenttime;

NOTE: PHP5 is required for this function due to the improvements with microtime() and the bc math module is also required (as we’re dealing with large numbers, you can check if you have the module in phpinfo).

Hope this help you.

After a lot of research, I finally figured this one out.

DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) { // Change `2.0` to the desired number of seconds.
   // Code you want to be delayed
}

This creates the desired "wait" effect in Swift 3 and Swift 4.

Inspired by a part of this answer.

Another possibility is that you are missing an .npmrc file if you are pulling any packages that are not publicly available.

You will need to add an .npmrc file at the root directory and add the private/internal registry inside of the .npmrc file like this:

registry=http://private.package.source/secret/npm-packages/

If you want to parse using InputStreams

public Object xmlToObject(String xmlDataString) {
        Object converted = null;
        try {
        
            JAXBContext jc = JAXBContext.newInstance(Response.class);
        
            Unmarshaller unmarshaller = jc.createUnmarshaller();
            InputStream stream = new ByteArrayInputStream(xmlDataString.getBytes(StandardCharsets.UTF_8));
            
            converted = unmarshaller.unmarshal(stream);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
        return converted;
    }

In most browsers, you need the Range and Selection objects. You specify each of the selection boundaries as a node and an offset within that node. For example, to set the caret to the fifth character of the second line of text, you'd do the following:

function setCaret() {
    var el = document.getElementById("editable")
    var range = document.createRange()
    var sel = window.getSelection()
    
    range.setStart(el.childNodes[2], 5)
    range.collapse(true)
    
    sel.removeAllRanges()
    sel.addRange(range)
}

<div id="editable" contenteditable="true">
  text text text<br>text text text<br>text text text<br>
</div>

<button id="button" onclick="setCaret()">focus</button>

IE < 9 works completely differently. If you need to support these browsers, you'll need different code.

jsFiddle example: http://jsfiddle.net/timdown/vXnCM/

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.Main_Activity);

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

I use these two methods depending on the usage. FIDDLE

<div class="img-div">
<img src="http://placekitten.com/g/400/200" />
</div>
<div class="circle-image"></div>

div.img-div{
    height:200px;
    width:200px;
    overflow:hidden;
    border-radius:50%;
}

.img-div img{
    -webkit-transform:translate(-50%);
    margin-left:100px;
}

.circle-image{
    width:200px;
    height:200px;
    border-radius:50%;
    background-image:url("http://placekitten.com/g/200/400");
    display:block;
    background-position-y:25% 
}

Just remember that string comparison like "x" > "X" is case-sensitive

"aa" < "ab" //true
"aa" < "Ab" //false

You can use .toLowerCase() to compare without case sensitivity.

There is one other option also .

row=(Row) sheet.getRow(i);
        if (row == null || isEmptyRow(row)) {
            return;
        }
Iterator<Cell> cells = row.cellIterator();
    while (cells.hasNext())
     {}

You can get also get this error trying to drop a non-existing foreign key. So when dropping foreign keys, always make sure they actually exist.

If the foreign key does exist, and you are still getting this error try the following:

SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL';

// Drop the foreign key here!

SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;

This always does the trick for me :)

//$sql - sql statement
//$em - entity manager

As Tmdean correctly pointed out you can use the Mid() function. The MSDN Library also has a great reference section on VBScript which you can find here:

VBScript Language Reference (MSDN Library)

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

From the documentation on expandtab:

To insert a real tab when expandtab is on, use CTRL-V<Tab>. See also :retab and ins-expandtab.
This option is reset when the paste option is set and restored when the paste option is reset.

So if you have a mapping for toggling the paste option, e.g.

set pastetoggle=<F2>

you could also do <F2>Tab<F2>.

I had this when requested SDK version didn't match the dependencies. You can click the line highlighted and fix this clicking the red light bulb. No need to find the actual version, just let the IDE figure it out for you. And add google repo to maven config.

You cannot decrypt this password again but there is another method named "pwdcompare". Here is a example how to use it with SQL syntax:

USE TEMPDB
GO
declare @hash varbinary (255)
CREATE TABLE tempdb..h (id_num int, hash varbinary (255))
SET @hash = pwdencrypt('123') -- encryption
INSERT INTO tempdb..h (id_num,hash) VALUES (1,@hash)
SET @hash = pwdencrypt('123')
INSERT INTO tempdb..h (id_num,hash) VALUES (2,@hash)
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 2
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
INSERT INTO tempdb..h (id_num,hash) 
VALUES (3,CONVERT(varbinary (255),
0x01002D60BA07FE612C8DE537DF3BFCFA49CD9968324481C1A8A8FE612C8DE537DF3BFCFA49CD9968324481C1A8A8))
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 3
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
DROP TABLE tempdb..h
GO

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

In math, ? means FOR ALL.

Unicode character (\u2200, ?).

This should work:

//iterate the array
for (int i = 0; i < theData.Length; i+=3)
{
    //grab 3 items at a time and do db insert, continue until all items are gone. 'theData' will always be divisible by 3.
    var a = theData[i];
    var b = theData[i + 1];
    var c = theData[i + 2];
}

I've been downvoted for this answer once. I'm pretty sure it is related to the use of theData.Length for the upperbound. The code as is works fine because array is guaranteed to be a multiple of three as the question states. If this guarantee wasn't in place, you would need to check the upper bound with theData.Length - 2 instead.

I had this problem and found that in my proxy generator, which I copied from another service, I forgot to change the name of the service.

I changed this...

Return New Service1DataClient(binding, New EndpointAddress(My.Settings.WCFServiceURL & "/Service1Data.svc"))

to...

Return New Service2DataClient(binding, New EndpointAddress(My.Settings.WCFServiceURL & "/Service2Data.svc"))

It was a simple code error, but nearly impossible to debug. I hope this saves someone time.

You can set <tr id="result_tr" style="display: none;"> and then show it back with JavaScript:

var result_style = document.getElementById('result_tr').style;
result_style.display = 'table-row';

I'd go with this:

private void myDataGridView_SelectionChanged(Object sender, EventArgs e)
{
    dgvSomeDataGridView.ClearSelection();  
}

I don't agree with the broad assertion that no DataGridView should be unselectable. Some UIs are built for tools or touchsreens, and allowing a selection misleads the user to think that selecting will actually get them somewhere.

Setting ReadOnly = true on the control has no impact on whether a cell or row can be selected. And there are visual and functional downsides to setting Enabled = false.

Another option is to set the control selected colors to be exactly what the non-selected colors are, but if you happen to be manipulating the back color of the cell, then this method yields some nasty results as well.

I found the log file at /usr/local/var/log/postgres.log on a mac installation from brew.

CSTR({number_field}, 0, '')

The second placeholder is for decimals.

The last placeholder is for thousands separator.

Assuming you have the date as a string (sorry it was unclear from your question if that is the case) could split the string on the - characters like so:

$date = "2068-06-15";
$split_date = split("-", $date);
$year = $split_date[0];

The clear way to achieve this,

For example:

If you have dataFile.txt on your current directory

import java.io.*;
import java.util.Scanner;
import java.io.FileNotFoundException;

public class readByLine
{
    public readByLine() throws FileNotFoundException
    {
        Scanner linReader = new Scanner(new File("dataFile.txt"));

        while (linReader.hasNext())
        {
            String line = linReader.nextLine();
            System.out.println(line);
        }
        linReader.close();

    }

    public static void main(String args[])  throws FileNotFoundException
    {
        new readByLine();
    }
}

The output like as below,

If you want to remove only line terminators that are valid on the current OS, you could do this:

text = text.replaceAll(System.getProperty("line.separator"), "");

If you want to make sure you remove any line separators, you can do it like this:

text = text.replaceAll("\\r|\\n", "");

Or, slightly more verbose, but less regexy:

text = text.replaceAll("\\r", "").replaceAll("\\n", "");

You're not actually passing the model to the Partial, you're passing a new ViewDataDictionary<LetLord.Models.Tenant>(). Try this:

@model LetLord.Models.Tenant
<div class="row-fluid">
    <div class="span4 well-border">
         @Html.Partial("~/Views/Tenants/_TenantDetailsPartial.cshtml", Model)
    </div>
</div>

If you want to select an individual hidden field, you can select it through the different selectors of jQuery :

<input type="hidden" id="hiddenField" name="hiddenField" class="hiddenField"/> 


$("#hiddenField").val(); //by id
$("[name='hiddenField']").val(); // by name
$(".hiddenField").val(); // by class

You can do it by making form and displaying it using ShowDialogBox....

Form.ShowDialog Method - Shows the form as a modal dialog box.

Example:

public void ShowMyDialogBox()
{
   Form2 testDialog = new Form2();

   // Show testDialog as a modal dialog and determine if DialogResult = OK.
   if (testDialog.ShowDialog(this) == DialogResult.OK)
   {
      // Read the contents of testDialog's TextBox.
      this.txtResult.Text = testDialog.TextBox1.Text;
   }
   else
   {
      this.txtResult.Text = "Cancelled";
   }
   testDialog.Dispose();
}

document.getElementById('myRadio').checked is a boolean value. It should be true or false

document.getElementById('myRadio').checked = "checked"; casts the string to a boolean, which is true.

document.getElementById('myRadio').checked = true; just assigns true without casting.

Use true as it is marginally more efficient and is more intention revealing to maintainers.

Found a Fix:

1. First ensure that printing is working from Report Manager (open a report in Report Manager and print from there).

2. If it works go to Step 3, if you received the same error you need to install the following patches on the Report Server.

You could try something like this:

I have initialzed the array for having value 5, you could put your number similarly.

int[] arr = new int[10]; // your initial array

arr = arr.Select(i => 5).ToArray(); // array initialized to 5.

One simply solution would be create a Dictionary with names and values. Then using Contains() you can find the right value.

Dictionary<string, string> months = new Dictionary<string, string>()
{
                { "january", "01"},
                { "february", "02"},
                { "march", "03"},
                { "april", "04"},
                { "may", "05"},
                { "june", "06"},
                { "july", "07"},
                { "august", "08"},
                { "september", "09"},
                { "october", "10"},
                { "november", "11"},
                { "december", "12"},
};
foreach (var month in months)
{
    if (StringThatContainsMonth.ToLower().Contains(month.Key))
    {
        string thisMonth = month.Value;
    }
}

Does the JS library define/initialize any well known variable on the window?

If so you could wait for the variable to appear. You can use

((JavascriptExecutor)driver).executeScript(String script, Object... args)

to test for this condition (something like: window.SomeClass && window.SomeClass.variable != null) and return a boolean true / false.

Wrap this in a WebDriverWait, and wait until the script returns true.
