You can implement Finite State Machine in two different ways.

Option 1:

Finite State machine with a pre-defined workflow : Recommended if you know all states in advance and state machine is almost fixed without any changes in future

1. Identify all possible states in your application

2. Identify all the events in your application

3. Identify all the conditions in your application, which may lead state transition

4. Occurrence of an event may cause transitions of state

5. Build a finite state machine by deciding a workflow of states & transitions.

   e.g If an event 1 occurs at State 1, the state will be updated and machine state may still be in state 1.

   If an event 2 occurs at State 1, on some condition evaluation, the system will move from State 1 to State 2

This design is based on State and Context patterns.

Have a look at Finite State Machine prototype classes.

Option 2:

Behavioural trees: Recommended if there are frequent changes to state machine workflow. You can dynamically add new behaviour without breaking the tree.

The base Task class provides a interface for all these tasks, the leaf tasks are the ones just mentioned, and the parent tasks are the interior nodes that decide which task to execute next.

The Tasks have only the logic they need to actually do what is required of them, all the decision logic of whether a task has started or not, if it needs to update, if it has finished with success, etc. is grouped in the TaskController class, and added by composition.

The decorators are tasks that “decorate” another class by wrapping over it and giving it additional logic.

Finally, the Blackboard class is a class owned by the parent AI that every task has a reference to. It works as a knowledge database for all the leaf tasks

Have a look at this article by Jaime Barrachina Verdia for more details

Let's start with this simple state diagram:

We have:

• 4 states (Inactive, Active, Paused, and Exited)
• 5 types of state transitions (Begin Command, End Command, Pause Command, Resume Command, Exit Command).

You can convert this to C# in a handful of ways, such as performing a switch statement on the current state and command, or looking up transitions in a transition table. For this simple state machine, I prefer a transition table, which is very easy to represent using a Dictionary:

using System;
using System.Collections.Generic;

namespace Juliet
{
    public enum ProcessState
    {
        Inactive,
        Active,
        Paused,
        Terminated
    }

    public enum Command
    {
        Begin,
        End,
        Pause,
        Resume,
        Exit
    }

    public class Process
    {
        class StateTransition
        {
            readonly ProcessState CurrentState;
            readonly Command Command;

            public StateTransition(ProcessState currentState, Command command)
            {
                CurrentState = currentState;
                Command = command;
            }

            public override int GetHashCode()
            {
                return 17 + 31 * CurrentState.GetHashCode() + 31 * Command.GetHashCode();
            }

            public override bool Equals(object obj)
            {
                StateTransition other = obj as StateTransition;
                return other != null && this.CurrentState == other.CurrentState && this.Command == other.Command;
            }
        }

        Dictionary<StateTransition, ProcessState> transitions;
        public ProcessState CurrentState { get; private set; }

        public Process()
        {
            CurrentState = ProcessState.Inactive;
            transitions = new Dictionary<StateTransition, ProcessState>
            {
                { new StateTransition(ProcessState.Inactive, Command.Exit), ProcessState.Terminated },
                { new StateTransition(ProcessState.Inactive, Command.Begin), ProcessState.Active },
                { new StateTransition(ProcessState.Active, Command.End), ProcessState.Inactive },
                { new StateTransition(ProcessState.Active, Command.Pause), ProcessState.Paused },
                { new StateTransition(ProcessState.Paused, Command.End), ProcessState.Inactive },
                { new StateTransition(ProcessState.Paused, Command.Resume), ProcessState.Active }
            };
        }

        public ProcessState GetNext(Command command)
        {
            StateTransition transition = new StateTransition(CurrentState, command);
            ProcessState nextState;
            if (!transitions.TryGetValue(transition, out nextState))
                throw new Exception("Invalid transition: " + CurrentState + " -> " + command);
            return nextState;
        }

        public ProcessState MoveNext(Command command)
        {
            CurrentState = GetNext(command);
            return CurrentState;
        }
    }


    public class Program
    {
        static void Main(string[] args)
        {
            Process p = new Process();
            Console.WriteLine("Current State = " + p.CurrentState);
            Console.WriteLine("Command.Begin: Current State = " + p.MoveNext(Command.Begin));
            Console.WriteLine("Command.Pause: Current State = " + p.MoveNext(Command.Pause));
            Console.WriteLine("Command.End: Current State = " + p.MoveNext(Command.End));
            Console.WriteLine("Command.Exit: Current State = " + p.MoveNext(Command.Exit));
            Console.ReadLine();
        }
    }
}

As a matter of personal preference, I like to design my state machines with a GetNext function to return the next state deterministically, and a MoveNext function to mutate the state machine.

Real-Time Object-Oriented Modeling was fantastic (published in 1994 and now selling for as little as 81 cents, plus $3.99 shipping).

You can use sdp size unit instead of dp size unit. The sdp size unit is relative to the screen size and therefor is often preferred for targeting multiple screen sizes.

Use it carefully! for example, in most cases you still need to design a different layout for tablets.

It's OK to run Docker-in-Docker (DinD) and in fact Docker (the company) has an official DinD image for this.

The caveat however is that it requires a privileged container, which depending on your security needs may not be a viable alternative.

The alternative solution of running Docker using sibling containers (aka Docker-out-of-Docker or DooD) does not require a privileged container, but has a few drawbacks that stem from the fact that you are launching the container from within a context that is different from that one in which it's running (i.e., you launch the container from within a container, yet it's running at the host's level, not inside the container).

I wrote a blog describing the pros/cons of DinD vs DooD here.

Having said this, Nestybox (a startup I just founded) is working on a solution that runs true Docker-in-Docker securely (without using privileged containers). You can check it out at www.nestybox.com.

As of 10/22/2019, I think the best answer is simply

conda install opencv

It appears opencv is now in the main Anaconda channel.

To see which packages (including opencv) are in the main Anaconda channel go to Anaconda Package Lists and follow the link corresponding to your python version and os version.

Read the data:

foo <- read.table(text="1 349
  1 393
  1 392
  4 459
  3 49
  3 32
  2 94")

And sort:

foo[order(foo$V1),]

This relies on the fact that order keeps ties in their original order. See ?order.

In order to get rgba integer value instead of float value, we can do

rgba = cmap(0.5,bytes=True)

So to simplify the code based on answer from Ffisegydd, the code would be like this:

#import colormap
from matplotlib import cm

#normalize item number values to colormap
norm = matplotlib.colors.Normalize(vmin=0, vmax=1000)

#colormap possible values = viridis, jet, spectral
rgba_color = cm.jet(norm(400),bytes=True) 

#400 is one of value between 0 and 1000

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

I had a similar issue and solved it with a patch to ec2.py and adding some configuration parameters to ec2.ini. The patch takes the value of ec2_key_name, prefixes it with the ssh_key_path, and adds the ssh_key_suffix to the end, and writes out ansible_ssh_private_key_file as this value.

The following variables have to be added to ec2.ini in a new 'ssh' section (this is optional if the defaults match your environment):

[ssh]
# Set the path and suffix for the ssh keys
ssh_key_path = ~/.ssh
ssh_key_suffix = .pem

Here is the patch for ec2.py:

204a205,206
>     'ssh_key_path': '~/.ssh',
>     'ssh_key_suffix': '.pem',
422a425,428
>         # SSH key setup
>         self.ssh_key_path = os.path.expanduser(config.get('ssh', 'ssh_key_path'))
>         self.ssh_key_suffix = config.get('ssh', 'ssh_key_suffix')
> 
1490a1497
>         instance_vars["ansible_ssh_private_key_file"] = os.path.join(self.ssh_key_path, instance_vars["ec2_key_name"] + self.ssh_key_suffix)

Sad side note: I decided to use C++ IO to be consistent with boost based code. From answers to this question I chose while (std::getline(std::cin, line)). Using g++ version 4.5.3 (-O3) in cygwin (mintty) i got 2 MB/s throughput. Microsoft Visual C++ 2010 (/O2) made it 40 MB/s for the same code.

After rewriting the IO to pure C while (fgets(buf, 100, stdin)) the throughput jumped to 90 MB/s in both tested compilers. That makes a difference for any input bigger than 10 MB...

I created a button...

This is where you've gone wrong. You haven't created a button, you've created an anchor element. If you had used a button element instead, you wouldn't have this problem:

<button type="button" data-toggle="modal" data-target="#myModal" data-role="disabled">
    Connect
</button>

If you are going to continue using an a element instead, at the very least you should give it a role attribute set to "button" and drop the href attribute altogether:

<a role="button" ...>

Once you've done that you can introduce a piece of JavaScript which calls event.preventDefault() - here with event being your click event.

A simpler approach is to use nested functions. Then you can chain them in an object-oriented fashion. Example:

jQuery.fn.MyPlugin = function()
{
  var _this = this;
  var a = 1;

  jQuery.fn.MyPlugin.DoSomething = function()
  {
    var b = a;
    var c = 2;

    jQuery.fn.MyPlugin.DoSomething.DoEvenMore = function()
    {
      var d = a;
      var e = c;
      var f = 3;
      return _this;
    };

    return _this;
  };

  return this;
};

And here's how to call it:

var pluginContainer = $("#divSomeContainer");
pluginContainer.MyPlugin();
pluginContainer.MyPlugin.DoSomething();
pluginContainer.MyPlugin.DoSomething.DoEvenMore();

Be careful though. You cannot call a nested function until it has been created. So you cannot do this:

var pluginContainer = $("#divSomeContainer");
pluginContainer.MyPlugin();
pluginContainer.MyPlugin.DoSomething.DoEvenMore();
pluginContainer.MyPlugin.DoSomething();

The DoEvenMore function doesn't even exist because the DoSomething function hasn't been run yet which is required to create the DoEvenMore function. For most jQuery plugins, you really are only going to have one level of nested functions and not two as I've shown here.
Just make sure that when you create nested functions that you define these functions at the beginning of their parent function before any other code in the parent function gets executed.

Finally, note that the "this" member is stored in a variable called "_this". For nested functions, you should return "_this" if you need a reference to the instance in the calling client. You cannot just return "this" in the nested function because that will return a reference to the function and not the jQuery instance. Returning a jQuery reference allows you to chain intrinsic jQuery methods on return.

You can pre-fetch your data by using Resolvers in Angular2+, Resolvers process your data before your Component fully be loaded.

There are many cases that you want to load your component only if there is certain thing happening, for example navigate to Dashboard only if the person already logged in, in this case Resolvers are so handy.

Look at the simple diagram I created for you for one of the way you can use the resolver to send the data to your component.

Applying Resolver to your code is pretty simple, I created the snippets for you to see how the Resolver can be created:

import { Injectable } from '@angular/core';
import { Router, Resolve, RouterStateSnapshot, ActivatedRouteSnapshot } from '@angular/router';
import { MyData, MyService } from './my.service';

@Injectable()
export class MyResolver implements Resolve<MyData> {
  constructor(private ms: MyService, private router: Router) {}

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise<MyData> {
    let id = route.params['id'];

    return this.ms.getId(id).then(data => {
      if (data) {
        return data;
      } else {
        this.router.navigate(['/login']);
        return;
      }
    });
  }
}

and in the module:

import { MyResolver } from './my-resolver.service';

@NgModule({
  imports: [
    RouterModule.forChild(myRoutes)
  ],
  exports: [
    RouterModule
  ],
  providers: [
    MyResolver
  ]
})
export class MyModule { }

and you can access it in your Component like this:

/////
 ngOnInit() {
    this.route.data
      .subscribe((data: { mydata: myData }) => {
        this.id = data.mydata.id;
      });
  }
/////

And in the Route something like this (usually in the app.routing.ts file):

////
{path: 'yourpath/:id', component: YourComponent, resolve: { myData: MyResolver}}
////

For example css files are in folder named CSS and html files are in folder HTML, and both these are in folder named XYZ means we refer css files in html as

<link rel="stylesheet" type="text/css" href="./../CSS/style.css" />

Here .. moves up to HTML
and . refers to the current directory XYZ

---by this logic you would just reference as:

<link rel="stylesheet" type="text/css" href="CSS/style.css" />

You can create a Text Field that doesn't accept any events on top of a Text View like this:

CGRect frameRect = descriptionTextField.frame;
frameRect.size.height = 50;
descriptionTextField.frame = frameRect;
descriptionTextView.frame = frameRect;
descriptionTextField.backgroundColor = [UIColor clearColor];
descriptionTextField.enabled = NO;
descriptionTextView.layer.cornerRadius = 5;
descriptionTextView.clipsToBounds = YES;

This article talks about setting the timeouts on the server level. http://www.coderanch.com/t/364207/Servlets/java/Servlet-Timeout-two-ways

What is causing the application to go into infinite loop? If you are opening connections to other resources, you might want to put timeouts on those connections and sending appropriate response when those time out occurs.

The CSS3 appearance property provides a simple way to style any element (including an anchor) with a browser's built-in <button> styles:

a.btn {_x000D_
  -webkit-appearance: button;_x000D_
  -moz-appearance: button;_x000D_
  appearance: button;_x000D_
}

<body>_x000D_
  <a class="btn">CSS Button</a>_x000D_
</body>

CSS Tricks has a nice outline with more details on this. Keep in mind that no version of Internet Explorer currently supports this according to caniuse.com.

Take a look at this answer: ImportError: no module named win32api

You can use

pip install pypiwin32

Although the accepted answer is absolutely clear, I just wanted to check efficiency in terms of time.

The best way is to print joined string of numbers converted to strings.

print(" ".join(list(map(str,l))))

Note that I used map instead of loop. I wrote a little code of all 4 different ways to compare time:

import time as t

a, b = 10, 210000
l = list(range(a, b))
tic = t.time()
for i in l:
    print(i, end=" ")

print()
tac = t.time()
t1 = (tac - tic) * 1000
print(*l)
toe = t.time()
t2 = (toe - tac) * 1000
print(" ".join([str(i) for i in l]))
joe = t.time()
t3 = (joe - toe) * 1000
print(" ".join(list(map(str, l))))
toy = t.time()
t4 = (toy - joe) * 1000
print("Time",t1,t2,t3,t4)

Result:

Time 74344.76 71790.83 196.99 153.99

The output was quite surprising to me. Huge difference of time in cases of 'loop method' and 'joined-string method'.

Conclusion: Do not use loops for printing list if size is too large( in order of 10**5 or more).

Here are the two main approaches. I prefer this one for its readability:

bar <- subset(foo, location == "there")

Note that you can string together many conditionals with & and | to create complex subsets.

The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there" returns a vector of T and F values that is the same length as the rows of foo. You can do this to return only rows where the condition returns true.

foo[foo$location == "there", ]

I've built a function that deals with plotting FFT of real signals. The extra bonus in my function relative to the previous answers is that you get the actual amplitude of the signal.

Also, because of the assumption of a real signal, the FFT is symmetric, so we can plot only the positive side of the x-axis:

import matplotlib.pyplot as plt
import numpy as np
import warnings


def fftPlot(sig, dt=None, plot=True):
    # Here it's assumes analytic signal (real signal...) - so only half of the axis is required

    if dt is None:
        dt = 1
        t = np.arange(0, sig.shape[-1])
        xLabel = 'samples'
    else:
        t = np.arange(0, sig.shape[-1]) * dt
        xLabel = 'freq [Hz]'

    if sig.shape[0] % 2 != 0:
        warnings.warn("signal preferred to be even in size, autoFixing it...")
        t = t[0:-1]
        sig = sig[0:-1]

    sigFFT = np.fft.fft(sig) / t.shape[0]  # Divided by size t for coherent magnitude

    freq = np.fft.fftfreq(t.shape[0], d=dt)

    # Plot analytic signal - right half of frequence axis needed only...
    firstNegInd = np.argmax(freq < 0)
    freqAxisPos = freq[0:firstNegInd]
    sigFFTPos = 2 * sigFFT[0:firstNegInd]  # *2 because of magnitude of analytic signal

    if plot:
        plt.figure()
        plt.plot(freqAxisPos, np.abs(sigFFTPos))
        plt.xlabel(xLabel)
        plt.ylabel('mag')
        plt.title('Analytic FFT plot')
        plt.show()

    return sigFFTPos, freqAxisPos


if __name__ == "__main__":
    dt = 1 / 1000

    # Build a signal within Nyquist - the result will be the positive FFT with actual magnitude
    f0 = 200  # [Hz]
    t = np.arange(0, 1 + dt, dt)
    sig = 1 * np.sin(2 * np.pi * f0 * t) + \
        10 * np.sin(2 * np.pi * f0 / 2 * t) + \
        3 * np.sin(2 * np.pi * f0 / 4 * t) +\
        7.5 * np.sin(2 * np.pi * f0 / 5 * t)

    # Result in frequencies
    fftPlot(sig, dt=dt)
    # Result in samples (if the frequencies axis is unknown)
    fftPlot(sig)

jezrael's answer is good, but did not answer a question I had: Will getting the "sort" flag wrong mess up my data in any way? The answer is apparently "no", you are fine either way.

from pandas import DataFrame, concat

a = DataFrame([{'a':1,      'c':2,'d':3      }])
b = DataFrame([{'a':4,'b':5,      'd':6,'e':7}])

>>> concat([a,b],sort=False)
   a    c  d    b    e
0  1  2.0  3  NaN  NaN
0  4  NaN  6  5.0  7.0

>>> concat([a,b],sort=True)
   a    b    c  d    e
0  1  NaN  2.0  3  NaN
0  4  5.0  NaN  6  7.0

Also note that the Hangouts application will currently block my BroadcastReceiver from receiving SMS messages. I had to disable SMS functionality in the Hangouts application (Settings->SMS->Turn on SMS), before my SMS BroadcastReceived started getting fired.

Edit: It appears as though some applications will abortBroadcast() on the intent which will prevent other applications from receiving the intent. The solution is to increase the android:priority attribute in the intent-filter tag:

<receiver android:name="com.company.application.SMSBroadcastReceiver" >
  <intent-filter android:priority="500">
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
  </intent-filter>
</receiver>

See more details here: Enabling SMS support in Hangouts 2.0 breaks the BroadcastReceiver of SMS_RECEIVED in my app

If Source Date format isn't consistent there is some problem with substr function, e.g.:

1/1/2017 or 1/11/2017 or 11/11/2017 or 1/1/17 etc.

So I followed a different apporach using a temporary table. This snippet outputs 'YYYY-MM-DD' + time if exists.

Note that this version accepts Day/Month/Year format. If you want Month/Day/Year swap the first two variables DayPart and MonthPart. Also, two year dates '44-'99 assumes 1944-1999 whereas '00-'43 assumes 2000-2043.

 BEGIN;

    CREATE TEMP TABLE [DateconvertionTable] (Id TEXT PRIMARY KEY, OriginalDate  TEXT  , SepA  INTEGER,  DayPart TEXT,Rest1 TEXT, SepB  INTEGER,  MonthPart TEXT, Rest2 TEXT, SepC  INTEGER,  YearPart TEXT, Rest3 TEXT, NewDate TEXT);
    INSERT INTO [DateconvertionTable] (Id,OriginalDate)  SELECT SourceIdColumn, SourceDateColumn From  [SourceTable];

    --day Part (If day is first)

    UPDATE [DateconvertionTable] SET SepA=instr(OriginalDate ,'/');
    UPDATE [DateconvertionTable] SET DayPart=substr(OriginalDate,1,SepA-1) ;
    UPDATE [DateconvertionTable] SET Rest1=substr(OriginalDate,SepA+1);

    --Month Part (If Month is second)

    UPDATE [DateconvertionTable] SET SepB=instr(Rest1,'/');
    UPDATE [DateconvertionTable]  SET MonthPart=substr(Rest1, 1,SepB-1);
    UPDATE [DateconvertionTable] SET Rest2=substr(Rest1,SepB+1);

    --Year Part (3d)

    UPDATE [DateconvertionTable] SET SepC=instr(Rest2,' ');

           --Use Cases In case of time string included
    UPDATE [DateconvertionTable]  SET YearPart= CASE WHEN SepC=0 THEN Rest2 ELSE substr(Rest2,1,SepC-1)  END;

           --The Rest considered time
    UPDATE [DateconvertionTable]  SET Rest3= CASE WHEN SepC=0 THEN  '' ELSE substr(Rest2,SepC+1) END;

           -- Convert 1 digit day and month to 2 digit
    UPDATE [DateconvertionTable] SET DayPart=0||DayPart WHERE CAST(DayPart AS INTEGER)<10;
    UPDATE [DateconvertionTable] SET MonthPart=0||MonthPart WHERE CAST(MonthPart AS INTEGER)<10;

           --If there is a need to convert 2 digit year to 4 digit year, make some assumptions...
    UPDATE [DateconvertionTable] SET YearPart=19||YearPart WHERE CAST(YearPart AS INTEGER)>=44 AND CAST(YearPart AS INTEGER)<100;
    UPDATE [DateconvertionTable] SET YearPart=20||YearPart WHERE CAST(YearPart AS INTEGER)<44 AND CAST(YearPart AS INTEGER)<100;

    UPDATE [DateconvertionTable] SET NewDate = YearPart  || '-' || MonthPart || '-' || DayPart || ' ' || Rest3;  

    UPDATE [SourceTable] SET SourceDateColumn=(Select NewDate FROM DateconvertionTable WHERE [DateconvertionTable].id=SourceIdColumn);
    END;

  public TargetType(OrigType origType) {
    Prop1 = origType.Prop1;
    Prop2 = origType.Prop2;
  }
}

var origList = new List<OrigType>();
var targetList = origList.Select(s=> new TargetType(s)).ToList();  

The Linq line is more soft! ;-)

Yes, you can. But if you have non-unique entries on your table, it will fail. Here is the how to add unique constraint on your table. If you're using PostgreSQL 9.x you can follow below instruction.

CREATE UNIQUE INDEX constraint_name ON table_name (columns);

If input datetime object is in UTC:

>>> dt = datetime(2008, 1, 1, 0, 0, 0, 0)
>>> timestamp = (dt - datetime(1970, 1, 1)).total_seconds()
1199145600.0

Note: it returns float i.e., microseconds are represented as fractions of a second.

If input date object is in UTC:

>>> from datetime import date
>>> utc_date = date(2008, 1, 1)
>>> timestamp = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * 24*60*60
1199145600

See more details at Converting datetime.date to UTC timestamp in Python.

$.ajax({
  url:href,
  type:'get',
  success: function(data){
   console.log($(data)); 
  }
});

This console log gets an array like object: [meta, title, ,], very strange

You can use JavaScript:

var doc = document.documentElement.cloneNode()
doc.innerHTML = data
$content = $(doc.querySelector('#content'))

The "I literally tried everything else" answer:

This problem will also occur if you don't have an upto date Android Support Library and Android Support Repository. Just install using the SDK manager.

Hmm, there are many solution written for php version lower than 7.1.

Here is an other simple one for those who doesn't want catch all exception and can't make common interfaces:

<?php
$ex = NULL
try {
    /* ... */
} catch (FirstException $ex) {
    // just do nothing here
} catch (SecondException $ex) {
    // just do nothing here
}
if ($ex !== NULL) {
    // handle those exceptions here!
}
?>

You can also get this error if you fail to include .htaccess or have a problem in it. The file should be something like this

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews -Indexes
</IfModule>

RewriteEngine On

# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .

Try using the wget library for python. You can find the documentation for it here.

I had the same issue and managed to solve this by:

Wrapping the object with an element set to block or inline-block

<a>
    <span>
        <object></object>
    </span>
</a>

Adding to <a> tag:

display: inline-block;
position: relative; 
z-index: 1;

and to the <span> tag:

display: inline-block;

and to the <object> tag:

position: relative; 
z-index: -1

See an example here: http://dabblet.com/gist/d6ebc6c14bd68a4b06a6

Found via comment 20 here https://bugzilla.mozilla.org/show_bug.cgi?id=294932

I'm referring to TT's post and suggest the following approach:

Reference the System.Web dll in your model and use System.Web.Caching.Cache

public string[] GetNames()
{ 
    var noms = Cache["names"];
    if(noms == null) 
    {    
        noms = DB.GetNames();
        Cache["names"] = noms; 
    }

    return ((string[])noms);
}

You should not return a value re-read from the cache, since you'll never know if at that specific moment it is still in the cache. Even if you inserted it in the statement before, it might already be gone or has never been added to the cache - you just don't know.

So you add the data read from the database and return it directly, not re-reading from the cache.

I know that this question is old, but it is first in google searches

For the windows 8.1, the tools can be downloaded here
http://support.microsoft.com/kb/2693643

For the windows 10, the tools can be downloaded here

EDIT: After installing the Windows 10 2015 "Fall Update", I had to reinstall the remote server administration tools.

Firstly you can find duplicate rows and find count of rows is used how many times and order it by number like this;

SELECT q.id,q.name,q.password,q.NID,(select count(*) from UserInfo k where k.NID= q.NID) as Count,_x000D_
(_x000D_
  CASE q.NID_x000D_
  WHEN @curCode THEN_x000D_
   @curRow := @curRow + 1_x000D_
  ELSE_x000D_
   @curRow := 1_x000D_
  AND @curCode := q.NID_x000D_
  END_x000D_
 ) AS No_x000D_
FROM UserInfo q,_x000D_
(_x000D_
  SELECT_x000D_
   @curRow := 1,_x000D_
   @curCode := ''_x000D_
 ) rt_x000D_
WHERE q.NID IN_x000D_
(_x000D_
    SELECT NID_x000D_
    FROM UserInfo_x000D_
    GROUP BY NID_x000D_
    HAVING COUNT(*) > 1_x000D_
) 

after that create a table and insert result to it.

create table CopyTable _x000D_
SELECT q.id,q.name,q.password,q.NID,(select count(*) from UserInfo k where k.NID= q.NID) as Count,_x000D_
(_x000D_
  CASE q.NID_x000D_
  WHEN @curCode THEN_x000D_
   @curRow := @curRow + 1_x000D_
  ELSE_x000D_
   @curRow := 1_x000D_
  AND @curCode := q.NID_x000D_
  END_x000D_
 ) AS No_x000D_
FROM UserInfo q,_x000D_
(_x000D_
  SELECT_x000D_
   @curRow := 1,_x000D_
   @curCode := ''_x000D_
 ) rt_x000D_
WHERE q.NID IN_x000D_
(_x000D_
    SELECT NID_x000D_
    FROM UserInfo_x000D_
    GROUP BY NID_x000D_
    HAVING COUNT(*) > 1_x000D_
) 

Finally, delete dublicate rows.No is start 0. Except fist number of each group delete all dublicate rows.

delete from  CopyTable where No!= 0;

First call startactivity() then use finish()

This is a great solution! With a few additional CSS rules you can format it just like an MS Word outline list with a hanging first line indent:

OL { 
  counter-reset: item; 
}
LI { 
  display: block; 
}
LI:before { 
  content: counters(item, ".") "."; 
  counter-increment: item; 
  padding-right:10px; 
  margin-left:-20px;
}

You can do this in plain JavaScript, use Array.prototype.join:

arrayName.join(delimiter);

Yes, there is a module fs-extra. There is a method .emptyDir() inside this module which does the job. Here is an example:

const fsExtra = require('fs-extra')

fsExtra.emptyDirSync(fileDir)

There is also an asynchronous version of this module too. Anyone can check out the link.

In general you put your translations in resource files, e.g. resources.resx.

Each specific culture has a different name, e.g. resources.nl.resx, resources.fr.resx, resources.de.resx, …

Now the most important part of a solution is to maintain your translations. In Visual Studio install the Microsoft MAT tool: Multilingual App Toolkit (MAT). Works with winforms, wpf, asp.net (core), uwp, …

In general, e.g. for a WPF solution, in the WPF project

• Install the Microsoft MAT extension for Visual Studio.
• In the Solution Explorer, navigate to your Project > Properties > AssemblyInfo.cs
• Add in AssemblyInfo.cs your default, neutral language (in my case English): [assembly: System.Resources.NeutralResourcesLanguage("en")]
• Select your project in Solution Explorer and in Visual Studio, from the top menu, click "Tools" > "Multilingual App Toolkit" > "Enable Selection", to enable MAT for the project.
  • Now Right mouse click on the project in Solution Explorer, select "Multilingual App Toolkit" > "Add translation languages…" and select the language that you want to add translations for. e.g. Dutch.

What you will see is that a new folder will be created, called "MultilingualResources" containing a ....nl.xlf file.

The only thing you now have to do is:

1. add your translation to your default resources.resx file (in my case English)
2. Translate by clicking the .xlf file (NOT the .resx file) as the .xlf files will generate/update the .resx files.

(the .xlf files should open with the "Multilingual Editor", if this is not the case, right mouse click on the .xlf file, select "Open With…" and select "Multilingual Editor".

Have fun! now you can also see what has not been translated, export translations in xlf to external translation companies, import them again, recycle translations from other projects etc...

You can pass a C# Guid value directly to a SQL Stored Procedure by specifying SqlDbType.UniqueIdentifier.

Your method may look like this (provided that your only parameter is the Guid):

public static void StoreGuid(Guid guid)
{
    using (var cnx = new SqlConnection("YourDataBaseConnectionString"))
    using (var cmd = new SqlCommand {
        Connection = cnx,
        CommandType = CommandType.StoredProcedure,
        CommandText = "StoreGuid",
        Parameters = {
            new SqlParameter {
                ParameterName = "@guid",
                SqlDbType = SqlDbType.UniqueIdentifier, // right here
                Value = guid
            }
        }
    })
    {
        cnx.Open();
        cmd.ExecuteNonQuery();
    }
}

_{See also: SQL Server's uniqueidentifier}

Just call getArguments() in your Frag2's onCreateView() method:

public class Frag2 extends Fragment {

     public View onCreateView(LayoutInflater inflater,
         ViewGroup containerObject,
         Bundle savedInstanceState){
         //here is your arguments
         Bundle bundle=getArguments(); 

        //here is your list array 
        String[] myStrings=bundle.getStringArray("elist");   
     }
}

This exception also happens if don't use transactions properly. In my case, I put transaction.Commit() right after command.ExecuteReaderAsync(), and did not wait to commit the transaction until reader.ReadAsync() were called. The proper order:

1. Create transaction.
2. Create reader.
3. Read the data.
4. Commit the transaction.

$update = \DB::table('student') ->where('id', $data['id']) ->limit(1) ->update( [ 'name' => $data['name'], 'address' => $data['address'], 'email' => $data['email'], 'contactno' => $data['contactno'] ]); 

Because the operating system may not do so. The flush operation forces the file data into the file cache in RAM, and from there it's the OS's job to actually send it to the disk.

For anyone on Jersey 2.x without lambdas, use this:

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

public static Client getUnsecureClient() throws Exception 
{
    SSLContext sslcontext = SSLContext.getInstance("TLS");
    sslcontext.init(null, new TrustManager[]{new X509TrustManager() 
    {
            public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException{}
            public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException{}
            public X509Certificate[] getAcceptedIssuers()
            {
                return new X509Certificate[0];
            }

    }}, new java.security.SecureRandom());


    HostnameVerifier allowAll = new HostnameVerifier() 
    {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    return ClientBuilder.newBuilder().sslContext(sslcontext).hostnameVerifier(allowAll).build();
}

Tested with jersey-client 2.11 on JRE 1.7.

This should work:

from numpy import *

a = array([[1, 2, 3], [0, 3, NaN]])
where_are_NaNs = isnan(a)
a[where_are_NaNs] = 0

In the above case where_are_NaNs is:

In [12]: where_are_NaNs
Out[12]: 
array([[False, False, False],
       [False, False,  True]], dtype=bool)

Since at some point in the future the support for AAPT(1) will be deprecated, it would be good to identify the reason for the error you reported.
Could you provide the contents of the \app\src\main\res\layout\topic_view_header.xml file? From the question marks it is possible that you are using non-ASCII characters, which AAPT2 still has some trouble with. If it's indeed non-ASCII characters then please follow the bug on https://issuetracker.google.com/68262818.

Update: The issue is fixed in android gradle plugin version 3.2.0-alpha11 or newer.

I have created a small utility function, this works well for me

def display_text_max_col_width(df, width):
    with pd.option_context('display.max_colwidth', width):
        print(df)

display_text_max_col_width(train_df["Description"], 800)

I can change length of the width as per my requirement, without setting any option permanently.

So as I understand it, you need to pull out successive pairs of hex digits, then decode that 2-digit hex number and take the corresponding char:

String s = "...";
StringBuilder sb = new StringBuilder(s.length() / 2);
for (int i = 0; i < s.length(); i+=2) {
    String hex = "" + s.charAt(i) + s.charAt(i+1);
    int ival = Integer.parseInt(hex, 16);
    sb.append((char) ival);
}
String string = sb.toString();

Waking up an old thread here I see, but I felt the urge to add the "new" .xlsx format.

According to http://filext.com/file-extension/XLSX the extension for .xlsx is application/vnd.openxmlformats-officedocument.spreadsheetml.sheet. It might be a good idea to include it when checking for mime types!

Try next, but it's not useful for huge data...

SELECT DISTINCT Cat FROM (
  SELECT Category as Cat FROM MonitoringJob ORDER BY CreationDate DESC
);

Am going to try and add value to this very good question and to build on @BrittonKerin's question in one of the comments under @David Wolever's fantastic answer. Wanted to share here because I had the same challenge as @BrittonKerin and I got something working (i.e. just want to run a piece of code only IF the table doesn't exist).

        # for completeness lets do the routine thing of connections and cursors
        conn = sqlite3.connect(db_file, timeout=1000) 

        cursor = conn.cursor() 

        # get the count of tables with the name  
        tablename = 'KABOOM' 
        cursor.execute("SELECT count(name) FROM sqlite_master WHERE type='table' AND name=? ", (tablename, ))

        print(cursor.fetchone()) # this SHOULD BE in a tuple containing count(name) integer.

        # check if the db has existing table named KABOOM
        # if the count is 1, then table exists 
        if cursor.fetchone()[0] ==1 : 
            print('Table exists. I can do my custom stuff here now.... ')
            pass
        else: 
           # then table doesn't exist. 
           custRET = myCustFunc(foo,bar) # replace this with your custom logic

Just add the function reference to the $scope in the controller:

for example if you want the function MyFunction to work in ng-click just add to the controller:

app.controller("MyController", ["$scope", function($scope) {
   $scope.MyFunction = MyFunction;
}]);

Accoring to Joyent you shouldn’t mess with the stack property (which I see in lots of answers given here), because it will have a negative impact on performance. Here is what they say:

stack: generally, don't mess with this. Don't even augment it. V8 only computes it if someone actually reads the property, which improves performance dramatically for handlable errors. If you read the property just to augment it, you'll end up paying the cost even if your caller doesn't need the stack.

I like and would like to mention their idea of wrapping the original error which is a nice replacement for passing on the stack.

So here is how I create a custom error, considering the above mentioned:

I’ve put my solution into a module, here it is: https://www.npmjs.com/package/rerror

Have you tried redirecting all three I/O streams:

nohup ./yourprogram > foo.out 2> foo.err < /dev/null &

As other folks already mention, I will suggest not to use "sudo apt-get" to install node or any development library. You can download required version from https://nodejs.org/dist/v6.9.2/ and setup you own environment.

I will recommend tools like nvm and n, to manage you node version. It is very convenient to switch and work with these modules. https://github.com/creationix/nvm https://github.com/tj/n

Or write basic bash to download zip/tar, extract move folder and create a soft link. Whenever you need to update, just point the old soft link to new downloaded version. Like I have created for my own, you can refer: https://github.com/deepakshrma/NodeJs-4.0-Reference-Guide/blob/master/nodejs-installer.sh

Add this to your <head>:

<style type="text/css">
    textarea { border: none; }
</style>

Or do it directly on the textarea:

<textarea style="border: none"></textarea>

Adding [] when appending to fd works, but if you prefer to have your data grouped by file then I'd suggest doing it this way:

var files= document.getElementById('inpFile').files
var fd = new FormData()

for (let i = 0; i < files.length; i++) {
  fd.append(i, files[i])
}

Now your data will be sent grouped by file instead of grouped by attribute.

I got this error: "Type does not contain a definition for GetProperty" when tying the accepted answer.

This is what i ended up with:

using System.Reflection;

if (productModel.GetType().GetTypeInfo().GetDeclaredProperty(propertyName) != null)
{

}

I have the same problem today, stuck on the kb2999226 for over an hour. First, i thought it is because i am using a VM on my local machine. But decided to cancel the installation, then install kb2999226 first, then install the vs2015 community again, it works out much better, the installation move forward and progressing. thx.

The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

from django.contrib.auth.models import User
user = User.objects.create_user(username='john',
                                 email='[email protected]',
                                 password='glass onion')

Try Like this.

tv1.setText("  " + Integer.toString(X[i]) + "\n" + "+" + " " + Integer.toString(Y[i]));

It took me hours to understand that while working with Angular and PHP. Post data was not going to PHP in $_POST

in PHP code do the following. - Create a variable $angular_post_params - Then do the following $angular_http_params = (array)json_decode(trim(file_get_contents('php://input')));

now you can access your parameters like you do from $_POST

$angular_http_params["key"]

in case you were wondering about javascript....this is what i used

    var myApp = angular.module('appUsers', []);
    //var post_params = $.param({ request_type: "getListOfUsersWithRolesInfo" });
    var dataObj = {
        task_to_perform: 'getListOfUsersWithRolesInfo'
    };

    myApp.controller('ctrlListOfUsers', function ($scope, $http) {
        $http({
            method: 'POST',
            dataType: 'json',
            url: ajax_processor_url,
            headers: {
                'Content-Type': 'application/json'
            },
            data: dataObj,
            //transformRequest: function(){},
            timeout: 30000,
            cache: false
        }).
        success(function (rsp) {
            console.log("success");
            console.log(rsp);
        }).
        error(function (rsp) {
            console.log("error");
        });
    });

The best option is to stage everything but this file, and tell stash to keep the index with git stash save --keep-index, thus stashing your unstaged file:

$ git add .
$ git reset thefiletostash
$ git stash save --keep-index

As Dan points out, thefiletostash is the only one to be reset by the stash, but it also stashes the other files, so it's not exactly what you want.

If you wish to list all tables, you must use:

\dt *.*

to indicate that you want all tables in all schemas. This will include tables in pg_catalog, the system tables, and those in information_schema. There's no built-in way to say "all tables in all user-defined schemas"; you can, however, set your search_path to a list of all schemas of interest before running \dt.

You may want to do this programmatically, in which case psql backslash-commands won't do the job. This is where the INFORMATION_SCHEMA comes to the rescue. To list tables:

SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';

BTW, if you ever want to see what psql is doing in response to a backslash command, run psql with the -E flag. eg:

$ psql -E regress    
regress=# \list
********* QUERY **********
SELECT d.datname as "Name",
       pg_catalog.pg_get_userbyid(d.datdba) as "Owner",
       pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
       d.datcollate as "Collate",
       d.datctype as "Ctype",
       pg_catalog.array_to_string(d.datacl, E'\n') AS "Access privileges"
FROM pg_catalog.pg_database d
ORDER BY 1;
**************************

so you can see that psql is searching pg_catalog.pg_database when it gets a list of databases. Similarly, for tables within a given database:

SELECT n.nspname as "Schema",
  c.relname as "Name",
  CASE c.relkind WHEN 'r' THEN 'table' WHEN 'v' THEN 'view' WHEN 'i' THEN 'index' WHEN 'S' THEN 'sequence' WHEN 's' THEN 'special' WHEN 'f' THEN 'foreign table' END as "Type",
  pg_catalog.pg_get_userbyid(c.relowner) as "Owner"
FROM pg_catalog.pg_class c
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','')
      AND n.nspname <> 'pg_catalog'
      AND n.nspname <> 'information_schema'
      AND n.nspname !~ '^pg_toast'
  AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1,2;

It's preferable to use the SQL-standard, portable INFORMATION_SCHEMA instead of the Pg system catalogs where possible, but sometimes you need Pg-specific information. In those cases it's fine to query the system catalogs directly, and psql -E can be a helpful guide for how to do so.

You can use Sort

List<string> ListaServizi = new List<string>() { };
ListaServizi.Sort();

As I know you can't make array without size, but you can use

List<string> l = new List<string>() 

and then l.ToArray().

If the text you're putting in the TextView is short, it will not automatically expand to four lines. If you want the TextView to always have four lines regardless of the length of the text in it, set the android:lines attribute:

<TextView
    android:id="@+id/address1"
    android:gravity="left"
    android:layout_height="fill_parent"
    android:layout_width="wrap_content"
    android:maxLines="4"
    android:lines="4"
    android:text="Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."></TextView>

You can do this with TableRow, see below code

<TableRow >
        <TextView
            android:id="@+id/tv_description_heading"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="left"
            android:padding="8dp"
            android:text="@string/rating_review"
            android:textColor="@color/black"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/tv_description"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="left"
            android:maxLines="4"`enter code here`
            android:padding="8dp"
            android:text="The food test was very good."
            android:textColor="@color/black"
            android:textColorHint="@color/hint_text_color" />
    </TableRow>

What your looking for is the DefaultListModel - Dynamic String List Variable.

Here is a whole class that uses the DefaultListModel as though it were the TStringList of Delphi. The difference is that you can add Strings to the list without limitation and you have the same ability at getting a single entry by specifying the entry int.

FileName: StringList.java

public class StringList {

    public static String OutputAsString(DefaultListModel list, int entry) {
        return GetEntry(list, entry);
    }

    public static Object OutputAsObject(DefaultListModel list, int entry) {
        return GetEntry(list, entry);
    }

    public static int OutputAsInteger(DefaultListModel list, int entry) {
        return Integer.parseInt(list.getElementAt(entry).toString());
    }

    public static double OutputAsDouble(DefaultListModel list, int entry) {
        return Double.parseDouble(list.getElementAt(entry).toString());
    }

    public static byte OutputAsByte(DefaultListModel list, int entry) {
        return Byte.parseByte(list.getElementAt(entry).toString());
    }

    public static char OutputAsCharacter(DefaultListModel list, int entry) {
        return list.getElementAt(entry).toString().charAt(0);
    }

    public static String GetEntry(DefaultListModel list, int entry) {
        String result = "";
        result = list.getElementAt(entry).toString();
        return result;
    }

    public static void AddEntry(DefaultListModel list, String entry) {
        list.addElement(entry);
    }

    public static void RemoveEntry(DefaultListModel list, int entry) {
        list.removeElementAt(entry);
    }

    public static DefaultListModel StrToList(String input, String delimiter) {
        DefaultListModel dlmtemp = new DefaultListModel();
        input = input.trim();
        delimiter = delimiter.trim();
        while (input.toLowerCase().contains(delimiter.toLowerCase())) {
            int index = input.toLowerCase().indexOf(delimiter.toLowerCase());
            dlmtemp.addElement(input.substring(0, index).trim());
            input = input.substring(index + delimiter.length(), input.length()).trim();
        }
        return dlmtemp;
    }

    public static String ListToStr(DefaultListModel list, String delimiter) {
        String result = "";
        for (int i = 0; i < list.size(); i++) {
            result = list.getElementAt(i).toString() + delimiter;
        }
        result = result.trim();
        return result;
    }

    public static String LoadFile(String inputfile) throws IOException {
        int len;
        char[] chr = new char[4096];
        final StringBuffer buffer = new StringBuffer();
        final FileReader reader = new FileReader(new File(inputfile));
        try {
            while ((len = reader.read(chr)) > 0) {
                buffer.append(chr, 0, len);
            }
        } finally {
            reader.close();
        }
        return buffer.toString();
    }

    public static void SaveFile(String outputfile, String outputstring) {
        try {
            FileWriter f0 = new FileWriter(new File(outputfile));
            f0.write(outputstring);
            f0.flush();
            f0.close();
        } catch (IOException ex) {
            Logger.getLogger(StringList.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

OutputAs methods are for outputting an entry as int, double, etc... so that you don't have to convert from string on the other side.

SaveFile & LoadFile are to save and load strings to and from files.

StrToList & ListToStr are to place delimiters between each entry.

ex. 1<>2<>3<>4<> if "<>" is the delimiter and 1 2 3 & 4 are the entries.

AddEntry & GetEntry are to add and get strings to and from the DefaultListModel.

RemoveEntry is to delete a string from the DefaultListModel.

You use the DefaultListModel instead of an array here like this:

DefaultListModel list = new DefaultListModel();
//now that you have a list, you can run it through the above class methods.

If you need to have the script keep working on python2 and 3 as I did, this might help someone

import sys
if sys.version_info[0] >= 3:
    unicode = str

and can then just do for example

foo = unicode.lower(foo)

It's pretty simple :

public function myAction()
{
    $url = $this->generateUrl('blog_show', array('slug' => 'my-blog-post'));
}

Inside an action, $this->generateUrl is an alias that will use the router to get the wanted route, also you could do this that is the same :

$this->get('router')->generate('blog_show', array('slug' => 'my-blog-post'));

This is how I do it.

void SplitBufferToArray(char *buffer, char * delim, char ** Output) {

    int partcount = 0;
    Output[partcount++] = buffer;

    char* ptr = buffer;
    while (ptr != 0) { //check if the string is over
        ptr = strstr(ptr, delim);
        if (ptr != NULL) {
            *ptr = 0;
            Output[partcount++] = ptr + strlen(delim);
            ptr = ptr + strlen(delim);
        }

    }
    Output[partcount++] = NULL;
}

You can use the open event handler to apply additional styling:

 open: function(event) {
     $('.ui-dialog-buttonpane').find('button:contains("Cancel")').addClass('cancelButton');
 }

You can use:

>>> np.concatenate([array1, array2, ...]) 

e.g.

>>> import numpy as np
>>> a = [[1, 2, 3],[10, 20, 30]]
>>> b = [[100,200,300]]
>>> a = np.array(a) # not necessary, but numpy objects prefered to built-in
>>> b = np.array(b) # "^
>>> a
array([[ 1,  2,  3],
       [10, 20, 30]])
>>> b
array([[100, 200, 300]])
>>> c = np.concatenate([a,b])
>>> c
array([[  1,   2,   3],
       [ 10,  20,  30],
       [100, 200, 300]])
>>> print c
[[  1   2   3]
 [ 10  20  30]
 [100 200 300]]

Sometimes, you will come across trouble if a numpy array object is initialized with incomplete values for its shape property. This problem is fixed by assigning to the shape property the tuple: (array_length, element_length).

Note: Here, 'array_length' and 'element_length' are integer parameters, which you substitute values in for. A 'tuple' is just a pair of numbers in parentheses.

e.g.

>>> import numpy as np
>>> a = np.array([[1,2,3],[10,20,30]])
>>> b = np.array([100,200,300]) # initialize b with incorrect dimensions
>>> a.shape
(2, 3)
>>> b.shape
(3,)
>>> c = np.concatenate([a,b])

Traceback (most recent call last):
  File "<pyshell#191>", line 1, in <module>
    c = np.concatenate([a,b])
ValueError: all the input arrays must have same number of dimensions
>>> b.shape = (1,3)
>>> c = np.concatenate([a,b])
>>> c
array([[  1,   2,   3],
       [ 10,  20,  30],
       [100, 200, 300]])

As of current edited version of the post, you call setInterval at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.

You only need to "prime" setInterval once. Remove it from function and place it inside onload instead of direct function call.

You can run a python script via php, and outputs on browser.

Basically you have to call the python script this way:

$command = "python /path/to/python_script.py 2>&1";
$pid = popen( $command,"r");
while( !feof( $pid ) )
{
 echo fread($pid, 256);
 flush();
 ob_flush();
 usleep(100000);
}
pclose($pid);

Note: if you run any time.sleep() in you python code, it will not outputs the results on browser.

For full codes working, visit How to execute python script from php and show output on browser

As the others have said, there is no difference in the compiled code (IL) when you use either of the following:

var x1 = new object();
object x2 = new object;

I suppose Resharper warns you because it is [in my opinion] easier to read the first example than the second. Besides, what's the need to repeat the name of the type twice?

Consider the following and you'll get what I mean:

KeyValuePair<string, KeyValuePair<string, int>> y1 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

It's way easier to read this instead:

var y2 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

You can use the MultilineLabel component in the Jide Open Source Components.

Reading a local word list

If you're doing this repeatedly, I would download it locally and pull from the local file. *nix users can use /usr/share/dict/words.

Example:

word_file = "/usr/share/dict/words"
WORDS = open(word_file).read().splitlines()

Pulling from a remote dictionary

If you want to pull from a remote dictionary, here are a couple of ways. The requests library makes this really easy (you'll have to pip install requests):

import requests

word_site = "https://www.mit.edu/~ecprice/wordlist.10000"

response = requests.get(word_site)
WORDS = response.content.splitlines()

Alternatively, you can use the built in urllib2.

import urllib2

word_site = "https://www.mit.edu/~ecprice/wordlist.10000"

response = urllib2.urlopen(word_site)
txt = response.read()
WORDS = txt.splitlines()

Many good answers here already, although you also need to keep in mind that if you are doing long-running processing on the UI thread (generally a bad idea), then you won't see the marquee moving either.

Regarding to sampopes answer from Jun 6 '14 at 11:59:

I have insert a css style with font-size of 20px to display the excel data greater. In sampopes code the leading <tr> tags are missing, so i first output the headline and than the other tables lines within a loop.

function fnExcelReport()
{
    var tab_text = '<table border="1px" style="font-size:20px" ">';
    var textRange; 
    var j = 0;
    var tab = document.getElementById('DataTableId'); // id of table
    var lines = tab.rows.length;

    // the first headline of the table
    if (lines > 0) {
        tab_text = tab_text + '<tr bgcolor="#DFDFDF">' + tab.rows[0].innerHTML + '</tr>';
    }

    // table data lines, loop starting from 1
    for (j = 1 ; j < lines; j++) {     
        tab_text = tab_text + "<tr>" + tab.rows[j].innerHTML + "</tr>";
    }

    tab_text = tab_text + "</table>";
    tab_text = tab_text.replace(/<A[^>]*>|<\/A>/g, "");             //remove if u want links in your table
    tab_text = tab_text.replace(/<img[^>]*>/gi,"");                 // remove if u want images in your table
    tab_text = tab_text.replace(/<input[^>]*>|<\/input>/gi, "");    // reomves input params
    // console.log(tab_text); // aktivate so see the result (press F12 in browser)

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE "); 

     // if Internet Explorer
    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) {
        txtArea1.document.open("txt/html","replace");
        txtArea1.document.write(tab_text);
        txtArea1.document.close();
        txtArea1.focus(); 
        sa = txtArea1.document.execCommand("SaveAs", true, "DataTableExport.xls");
    }  
    else // other browser not tested on IE 11
        sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));  

    return (sa);
}   

Exception code 0xc0000005 is an Access Violation. An AV at fault offset 0x00000000 means that something in your service's code is accessing a nil pointer. You will just have to debug the service while it is running to find out what it is accessing. If you cannot run it inside a debugger, then at least install a third-party exception logger framework, such as EurekaLog or MadExcept, to find out what your service was doing at the time of the AV.

Quick review,

• DB - Define Byte. 8 bits
• DW - Define Word. Generally 2 bytes on a typical x86 32-bit system
• DD - Define double word. Generally 4 bytes on a typical x86 32-bit system

From x86 assembly tutorial,

The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.

Your num is 1 byte. Try declaring it with DD so that it becomes 4 bytes and matches with pop semantics.

remove the ios::binary from your modes in your ofstream and use studentPassword.c_str() instead of (char *)&studentPassword in your write.write()

I just use eco to do the job for me. eco is supported by Sprockets by default. It's a shorthand for Embedded Coffeescript which takes a eco file and compile into a Javascript template file, and the file will be treated like any other js files you have in your assets folder.

All you need to do is to create a template with extension .jst.eco and write some html code in there, and rails will automatically compile and serve the file with the assets pipeline, and the way to access the template is really easy: JST['path/to/file']({var: value}); where path/to/file is based on the logical path, so if you have file in /assets/javascript/path/file.jst.eco, you can access the template at JST['path/file']()

To make it work with angularjs, you can pass it into the template attribute instead of templateDir, and it will start working magically!

There are two problems in your code:

• The property is called visibility and not visiblity.
• It is not a property of the element itself but of its .style property.

It's easy to fix. Simple replace this:

document.getElementById("remember").visiblity

with this:

document.getElementById("remember").style.visibility

Here you have one nice and simple recursion for deleting all files in source directory including that directory:

function delete_dir($src) { 
    $dir = opendir($src);
    while(false !== ( $file = readdir($dir)) ) { 
        if (( $file != '.' ) && ( $file != '..' )) { 
            if ( is_dir($src . '/' . $file) ) { 
                delete_dir($src . '/' . $file); 
            } 
            else { 
                unlink($src . '/' . $file); 
            } 
        } 
    } 
    closedir($dir); 
    rmdir($src);

}

Function is based on recursion made for copying directory. You can find that function here: Copy entire contents of a directory to another using php

Also, StringBuffer is thread-safe, which StringBuilder is not.

So in a real-time situation when different threads are accessing it, StringBuilder could have an undeterministic result.

<?php 
    list($width, $height) = getimagesize("http://site.com/image.png"); 
    $arr = array('h' => $height, 'w' => $width );
?>

Google is using this to detect whether the device is online or in captive portal.

Shill, the connection manager for Chromium OS, attempts to detect services that are within a captive portal whenever a service transitions to the ready state. This determination of being in a captive portal or being online is done by attempting to retrieve the webpage http://clients3.google.com/generate_204. This well known URL is known to return an empty page with an HTTP status 204. If for any reason the web page is not returned, or an HTTP response other than 204 is received, then shill marks the service as being in the portal state.

Here is the relevant explanation from the Google Chrome Privacy Whitepaper:

In the event that Chrome detects SSL connection timeouts, certificate errors, or other network issues that might be caused by a captive portal (a hotel's WiFi network, for instance), Chrome will make a cookieless request to http://www.gstatic.com/generate_204 and check the response code. If that request is redirected, Chrome will open the redirect target in a new tab on the assumption that it's a login page. Requests to the captive portal detection page are not logged.

I guess I'm a little late (a lot late;-)) to this post, but I'd like to add Perst, an open source, object-oriented embedded database for Java &.NET. for your consideration. Perst is an open source / dual license embedded database for Java. The distribution is compatible with Google's Android platform, and also includes Perst Lite for Java ME. We've even built an Android benchmark and produced a whitepaper on the subject...you can take a look here: http://www.mcobject.com/index.cfm?fuseaction=download&pageid=581&sectionid=133

All the best, Chris

Ex Microsoft Developer's Opinion

I worked on a core team for the MSDN website. Now, I use c# razor for ecommerce sites with my programming team and we focus heavy on jQuery front end with back end c# razor pages and LINQ-Entity memory database so the pages are 1-2 millisecond response times even on nested for loops with queries and no page caching. We don't use MVC, just plain ASP.NET with razor pages being mapped with URL Rewrite module for IIS 7, no ASPX pages or ViewState or server-side event programming at all. It doesn't have the extra (unnecessary) layers MVC puts in code constructs for the regex challenged. Less is more for us. Its all lean and mean but I give props to MVC for its testability but that's all.

Razor pages have no event life cycle like ASPX pages. Its just rendering as one requested page. C# is such a great language and Razor gets out of its way nicely to let it do its job. The anonymous typing with generics and linq make life so easy with c# and razor pages. Using Razor pages will help you think and code lighter.

One of the drawback of Razor and MVC is there is no ViewState-like persistence. I needed to implement a solution for that so I ended up writing a jQuery plugin for that here -> http://www.jasonsebring.com/dumbFormState which is an HTML 5 offline storage supported plugin for form state that is working in all major browsers now. It is just for form state currently but you can use window.sessionStorage or window.localStorage very simply to store any kind of state across postbacks or even page requests, I just bothered to make it autosave and namespace it based on URL and form index so you don't have to think about it.

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

If you are working with apps, try cleaning solution. Fixed for me.

Let's say you have a tar file and you want to uncompress it after placing it in your container, remove it, you can use the COPY command to do this. Butt he various commands would be 1) Copy the tar file to the destination, 2). Uncompress it, 3) Remove the tar file. If you did this in 3 steps then there will be a new image created after each step. You can do this in one step using & but it becomes a hassle.

But you used ADD, then Docker will take care of everything for you and only one intermediate image will be created.

for a non-generic, simple solution to your exact problem:

homes.sort(
   function(a, b) {          
      if (a.city === b.city) {
         // Price is only important when cities are the same
         return b.price - a.price;
      }
      return a.city > b.city ? 1 : -1;
   });

This happens in our TFS build server some times (Gated check in). It is about workspace folder. I don't know why but workspace folder access sometimes corrupt. What I am doing to fix issue is deleting TFS build workspaces and deleting relevant workspace folders. TFS build machine then create new workspaces for itself and problem is fixed.

Tousif Ahmed's solution should work for local builds. Copy application folder to another place should do the same thing what I am doing in TFS build machine.

You need to use the as.Date formats correctly.

Eg.

x = '2012/07/25'
xd = as.Date(x,'%Y/%m/%d')
xd    # Prints "2012-07-25"

R date formats are similary to *nix ones.

Doing a typeof(xd) shows it as a double ie. days since 1970.

Additionally, for our Android friends (API Level 8):

import android.util.Base64

...

Base64.encodeToString(bytes, Base64.DEFAULT);

We can copy all columns from one table to another, existing table:

INSERT INTO table2 SELECT * FROM table1;

Or we can copy only the columns we want to into another, existing table:

INSERT INTO table2 (column_name(s)) SELECT column_name(s) FROM table1;

or SELECT * INTO BACKUP_TABLE1 FROM TABLE1

The most common complaint/question I've seen wrt PyInstaller is "my code can't find a data file which I definitely included in the bundle, where is it?", and it isn't easy to see what/where your code is searching because the extracted code is in a temp location and is removed when it exits. Add this bit of code to see what's included in your onefile and where it is, using @Jonathon Reinhart's resource_path()

for root, dirs, files in os.walk(resource_path("")):
    print(root)
    for file in files:
        print( "  ",file)

Similar to @joe_deniable 's answer the thing I found with my own projects was that gradle would output that kind of error when there was a misconfiguration of my system.

I discovered that by running gradlew installDebug or similar command from the terminal I got better output as to what the real problem was.

e.g. initially it turns out my JAVA_HOME was not setup correctly. Then I discovered it encountered errors because I didn't have a package space setup correctly. Etc.

String clsName = "Ex";  // use fully qualified name
Class cls = Class.forName(clsName);
Object clsInstance = (Object) cls.newInstance();

Check the Java Tutorial trail on Reflection at http://java.sun.com/docs/books/tutorial/reflect/TOC.html for further details.

So, the trick here is to use absolute positioning calc like this:

top: calc(50% - XYpx);
left: calc(50% - XYpx);

where XYpx is half the size of your image, in my case, the image was a square. Of course, in this now obsolete case, the image must also change its size proportionally in response to window resize to be able to remain at the center without looking out of proportion.

getopts works great if #1 you have it installed and #2 you intend to run it on the same platform. OSX and Linux (for example) behave differently in this respect.

Here is a (non getopts) solution that supports equals, non-equals, and boolean flags. For example you could run your script in this way:

./script --arg1=value1 --arg2 value2 --shouldClean

# parse the arguments.
COUNTER=0
ARGS=("$@")
while [ $COUNTER -lt $# ]
do
    arg=${ARGS[$COUNTER]}
    let COUNTER=COUNTER+1
    nextArg=${ARGS[$COUNTER]}

    if [[ $skipNext -eq 1 ]]; then
        echo "Skipping"
        skipNext=0
        continue
    fi

    argKey=""
    argVal=""
    if [[ "$arg" =~ ^\- ]]; then
        # if the format is: -key=value
        if [[ "$arg" =~ \= ]]; then
            argVal=$(echo "$arg" | cut -d'=' -f2)
            argKey=$(echo "$arg" | cut -d'=' -f1)
            skipNext=0

        # if the format is: -key value
        elif [[ ! "$nextArg" =~ ^\- ]]; then
            argKey="$arg"
            argVal="$nextArg"
            skipNext=1

        # if the format is: -key (a boolean flag)
        elif [[ "$nextArg" =~ ^\- ]] || [[ -z "$nextArg" ]]; then
            argKey="$arg"
            argVal=""
            skipNext=0
        fi
    # if the format has not flag, just a value.
    else
        argKey=""
        argVal="$arg"
        skipNext=0
    fi

    case "$argKey" in 
        --source-scmurl)
            SOURCE_URL="$argVal"
        ;;
        --dest-scmurl)
            DEST_URL="$argVal"
        ;;
        --version-num)

            exit
        ;;

If you are using moment.js:

moment().month("Jan").format("M");

Adding to @Paco Zarate's terrific answer above, if you want to transpose a table which has multiple types of columns, then add this to the end of line 39, so it only transposes int columns:

and C.system_type_id = 56   --56 = type int

Here is the full query that is being changed:

select @colsUnpivot = stuff((select ','+quotename(C.name)
from sys.columns as C
where C.object_id = object_id(@tableToPivot) and
      C.name <> @columnToPivot and C.system_type_id = 56    --56 = type int
for xml path('')), 1, 1, '')

To find other system_type_id's, run this:

select name, system_type_id from sys.types order by name

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

While it is really not possible to use a char or a string as the base for an enum, i think this is not what you really like to do.

Like you mentioned you'd like to have an enum of possibilities and show a string representation of this within a combo box. If the user selects one of these string representations you'd like to get out the corresponding enum. And this is possible:

First we have to link some string to an enum value. This can be done by using the DescriptionAttribute like it is described here or here.

Now you need to create a list of enum values and corresponding descriptions. This can be done by using the following method:

/// <summary>
/// Creates an List with all keys and values of a given Enum class
/// </summary>
/// <typeparam name="T">Must be derived from class Enum!</typeparam>
/// <returns>A list of KeyValuePair&lt;Enum, string&gt; with all available
/// names and values of the given Enum.</returns>
public static IList<KeyValuePair<T, string>> ToList<T>() where T : struct
{
    var type = typeof(T);

    if (!type.IsEnum)
    {
        throw new ArgumentException("T must be an enum");
    }

    return (IList<KeyValuePair<T, string>>)
            Enum.GetValues(type)
                .OfType<T>()
                .Select(e =>
                {
                    var asEnum = (Enum)Convert.ChangeType(e, typeof(Enum));
                    return new KeyValuePair<T, string>(e, asEnum.Description());
                })
                .ToArray();
}

Now you'll have a list of key value pairs of all enums and their description. So let's simply assign this as a data source for a combo box.

var comboBox = new ComboBox();
comboBox.ValueMember = "Key"
comboBox.DisplayMember = "Value";
comboBox.DataSource = EnumUtilities.ToList<Separator>();

comboBox.SelectedIndexChanged += (sender, e) =>
{
    var selectedEnum = (Separator)comboBox.SelectedValue;
    MessageBox.Show(selectedEnum.ToString());
}

The user sees all the string representations of the enum and within your code you'll get the desired enum value.

based on JustinStolle code (thank you), I wanted a solution that could be generic without having to specify the column names.

This sample is using the data of a temp table but of course it can be adjusted as required.

Here is what I got:

DECLARE @htmlTH VARCHAR(MAX) = '',
        @htmlTD VARCHAR(MAX)

--get header, columns name
SELECT @htmlTH = @htmlTH + '<TH>' +  name + '</TH>' FROM tempdb.sys.columns WHERE object_id = OBJECT_ID('tempdb.dbo.#results')

--convert table to XML PATH, ELEMENTS XSINIL is used to include NULL values
SET @htmlTD = (SELECT * FROM #results FOR XML PATH('TR'), ELEMENTS XSINIL)

--convert the way ELEMENTS XSINIL display NULL to display word NULL
SET @htmlTD = REPLACE(@htmlTD, ' xsi:nil="true"/>', '>NULL</TD>')
SET @htmlTD = REPLACE(@htmlTD, '<TR xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">', '<TR>')

--FOR XML PATH will set tags for each column name, <columnName1>abc</columnName1><columnName2>def</columnName2>
--this will replace all the column names with TD (html table data tag)
SELECT @htmlTD = REPLACE(REPLACE(@htmlTD, '<' + name + '>', '<TD>'), '</' + name + '>', '</TD>')
FROM tempdb.sys.columns WHERE object_id = OBJECT_ID('tempdb.dbo.#results')


SELECT '<TABLE cellpadding="2" cellspacing="2" border="1">'
     + '<TR>' + @htmlTH + '</TR>'
     + @htmlTD
     + '</TABLE>'

Here is good way to detect it (maybe funny, but works) and You can use necessary element so code is clear:

Example: css:

@media (max-width: 768px) {
    #someElement
    {
         background: pink
    }
}

and in document by jQuery:

if($('#someElement').css('background') == 'pink')
{
    doWhatYouNeed();
}

of course css property is any.

Object.withDefault = (defaultValue,o={}) => {
  return new Proxy(o, {
    get: (o, k) => (k in o) ? o[k] : defaultValue 
  });
}

o = Object.withDefault(42);
o.x  //=> 42

o.x = 10
o.x  //=> 10
o.xx //=> 42

@JimBastard's accepted answer appears to be dated, I had a look and that mailer lib hasn't been touched in over 7 months, has several bugs listed, and is no longer registered in npm.

nodemailer certainly looks like the best option, however the url provided in other answers on this thread are all 404'ing.

nodemailer claims to support easy plugins into gmail, hotmail, etc. and also has really beautiful documentation.

For me, the problem was in XML migrations. I deleted all tables and sequences and it works on next bootRun

Use git archive branch-index | tar -x -C your-folder-on-PC to clone a branch to another folder. I think, then you can copy any file that you need

I was looking for a Linux app to measure maximum memory used. valgrind is an excellent tool, but was giving me more information than I wanted. tstime seemed to be the best tool I could find. It measures "highwater" memory usage (RSS and virtual). See this answer.

This should work, at least according to the Search Filter Syntax article on MSDN network.

The "hang-up" you have noticed is probably just a delay. Try running the same query with narrower scope (for example the specific OU where the test object is located), as it may take very long time for processing if you run it against all AD objects.

You may also try separating the filter into two parts:

(|(displayName=*searchstring)(displayName=searchstring*))

You need to hook to console exit event and not your process.

http://geekswithblogs.net/mrnat/archive/2004/09/23/11594.aspx

Capture console exit C#

std::string replace(std::string base, const std::string from, const std::string to) {
    std::string SecureCopy = base;

    for (size_t start_pos = SecureCopy.find(from); start_pos != std::string::npos; start_pos = SecureCopy.find(from,start_pos))
    {
        SecureCopy.replace(start_pos, from.length(), to);
    }

    return SecureCopy;
}

List list = new ArrayList(coll);
Collections.sort(list);

As Erel Segal Halevi says below, if coll is already a list, you can skip step one. But that would depend on the internals of TreeBidiMap.

List list;
if (coll instanceof List)
  list = (List)coll;
else
  list = new ArrayList(coll);

All of these internally end up calling a method called InternalGetValueAsString. The difference between ToString and GetName would be that GetName has to verify a few things first:

1. The type you entered isn't null.
2. The type you entered is, in fact an enumeration.
3. The value you passed in isn't null.
4. The value you passed in is of a type that an enumeration can actually use as it's underlying type, or of the type of the enumeration itself. It uses GetType on the value to check this.

.ToString doesn't have to worry about any of these above issues, because it is called on an instance of the class itself, and not on a passed in version, therefore, due to the fact that the .ToString method doesn't have the same verification issues as the static methods, I would conclude that .ToString is the fastest way to get the value as a string.

As per the Android documentation for XML Attributes of android:layout_gravity, we can do it easily :)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageButton android:id="@+id/btnFindMe" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"

        android:layout_gravity="center"

        android:background="@drawable/findme"></ImageButton>

</LinearLayout>

You can create a dict and pass this as the data param to the dataframe constructor:

In [235]:

df = pd.DataFrame({'Gene':s.index, 'count':s.values})
df
Out[235]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Alternatively you can create a df from the series, you need to call reset_index as the index will be used and then rename the columns:

In [237]:

df = pd.DataFrame(s).reset_index()
df.columns = ['Gene', 'count']
df
Out[237]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Oh, I just found that command on PostgreSQL forum:

SELECT * FROM pg_stat_activity;

In my case the Procfile I used was breaking everything. Heroku looks for Procfile and applies its settings when launching the app - clearly the dev settings I used didn't make any sense for the prod server. I had to rename it to Procfile.dev and everything started working normally.

String a = "ABCD"

using this

a.toLowerCase();

all letters will convert to simple, "abcd"
using this

a.toUpperCase()

all letters will convert to Capital, "ABCD"

this conver first letter to capital:

a.substring(0,1).toUpperCase()

this conver other letter Simple

a.substring(1).toLowerCase();

we can get sum of these two

a.substring(0,1).toUpperCase() + a.substring(1).toLowerCase();

result = "Abcd"

Since your divs are position:absolute, they're not really nested as far as position is concerned. On your jsbin page I switched the order of the divs in the HTML to:

<div class="child"><div class="parent"></div></div>

and the red box covered the blue box, which I think is what you're looking for.

You can instanciate LocalReport

                FicheInscriptionBean fiche = new FicheInscriptionBean();
                fiche.ToFicheInscriptionBean(inscription);List<FicheInscriptionBean> list = new List<FicheInscriptionBean>();

                ReportDataSource rds = new ReportDataSource();
                rds = new ReportDataSource("InscriptionDataSet", list);

                MemoryStream ms = new MemoryStream();
                BitmapCaptcha.Save(ms, ImageFormat.Gif);
                var base64Data = Convert.ToBase64String(ms.ToArray());
                string QR_IMG = base64Data;

When you open a folder in VSCode, it will automatically scan the folder for typical project artifacts like project.json or solution files. From the status bar in the lower left side you can switch between solutions and projects.

I have read all the answers above, and some directed me to the problem, but not to the solution for the problem.

The root cause of the problem is disableSelection(). It is causing all the problems, but removing it is not a solution, as (at least in 2016 or slightly before), on touch-screen devices, you "have" to use this if you want to be able to move objects with jQuery.

The solution was to leave the disableSelection() to the sortable element, but also add a binding action just above:

 $('#your_selector_id form').bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(event) {
    event.stopImmediatePropagation();
 })

The form in the jQuery element is just to stop propagation on the form, as you might need propagation on some elements.

Since assertThat which was the old answer is now deprecated, I am posting the correct solution:

assertTrue(objectUnderTest instanceof TargetObject);

select DocumentFormat.OpenXml under references , view it's properties, and set the Copy Local option to True so that it copies it to the output folder. That worked for me.

as @DLeh says Use rather

var controller = DependencyResolver.Current.GetService<ControllerB>();

But, giving the controller, a controlller context is important especially when you need to access the User object, Server object, or the HttpContext inside the 'child' controller.

I have added a line of code:

controller.ControllerContext = new ControllerContext(Request.RequestContext, controller);

or else you could have used System.Web to acces the current context too, to access Server or the early metioned objects

NB: i am targetting the framework version 4.6 (Mvc5)

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

you can try this

<%= Html.TextBoxFor(x => x.Age, new { @Value = "0"}) %>

Actually you can use a switch statement with Strings in Java...unfortunately this is a new feature of Java 7, and most people are not using Java 7 yet because it's so new.

Best Way to Refresh Adapter/ListView on Android

Not only calling notifyDataSetChanged() will refresh the ListView data, setAdapter() must be called before to load the information correctly:

  listView.setAdapter(adapter);
  adapter.notifyDataSetChanged();

Actually, Laravel 4 does have a table rename function in Illuminate/Database/Schema/Builder.php, it's just undocumented at the moment: Schema::rename($from, $to);.

Solutions proposed here either didn't work for me or where to large, so I was looking for something else and found the solution proposed by @dighan on bountysource.com/issues/

So here is the code that solved my problem:

var media = document.getElementById("YourVideo");
const playPromise = media.play();
if (playPromise !== null){
    playPromise.catch(() => { media.play(); })
}

It still throws an error into console, but at least the video is playing :)

In Webdriver, you should use driver.switchTo().defaultContent(); to get out of a frame. You need to get out of all the frames first, then switch into outer frame again.

// between step 4 and step 5
// remove selenium.selectFrame("relative=up");
driver.switchTo().defaultContent(); // you are now outside both frames
driver.switchTo().frame("cq-cf-frame");
// now continue step 6
driver.findElement(By.xpath("//button[text()='OK']")).click(); 

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)

Go to Menu Tool -> SQL Output, Run the PL/SQL statement, the output will show on SQL Output panel.

This is going to work for all situations while working with width.

`<asp:TemplateField HeaderText="DATE">

Using pyquaternion is extremely simple; to install it (while still in python), run in your console:

import pip;
pip.main(['install','pyquaternion'])

Once installed:

  from pyquaternion import Quaternion
  v = [3,5,0]
  axis = [4,4,1]
  theta = 1.2 #radian
  rotated_v = Quaternion(axis=axis,angle=theta).rotate(v)

The accepted answer didn't work for me as my page jumped slightly on click, messing up my scroll animation.

I decided to update the entire URL using window.history.replaceState rather than using the window.location.hash method. Thus circumventing the hashChange event fired by the browser.

// Only fire when URL has anchor
$('a[href*="#"]:not([href="#"])').on('click', function(event) {

    // Prevent default anchor handling (which causes the page-jumping)
    event.preventDefault();

    if ( location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname ) {
        var target = $(this.hash);
        target = target.length ? target : $('[name=' + this.hash.slice(1) +']');

        if ( target.length ) {    
            // Smooth scrolling to anchor
            $('html, body').animate({
                scrollTop: target.offset().top
            }, 1000);

            // Update URL
            window.history.replaceState("", document.title, window.location.href.replace(location.hash, "") + this.hash);
        }
    }
});

Recently I have faced the similar issue in Azure Windows Server 2012 r2 . Tried all option with and without Anaconda but none of them helped. After lot of findings I found that mfplat.dll was missing which is related to Window Media Service.

Hence you have to manually install the features so that you can get dll related to window media service.

1.Turn windows features on or off

2.Skip the roles screen and directly go to Feature screen

3.Select "Desktop Experience" under "User Interfaces and Infrastructure"

After this all required dll of media services for opencv would be available.

So if you are planning to run your code in cloud(Window Server) then please dont forget to select Desktop Experience feature.

Maybe?

I used to add files beyond symlinks for quite some time now. This used to work just fine, without making any special arrangements. Since I updated to Git 1.6.1, this does not work any more.

You may be able to switch to Git 1.6.0 to make this work. I hope that a future version of Git will have a flag to git-add allowing it to follow symlinks again.

Try this:

DECLARE UserCursor CURSOR LOCAL FAST_FORWARD FOR
SELECT
    spid
FROM
    master.dbo.sysprocesses
WHERE DB_NAME(dbid) = 'dbname'--replace the dbname with your database
DECLARE @spid SMALLINT
DECLARE @SQLCommand VARCHAR(300)
OPEN UserCursor
FETCH NEXT FROM UserCursor INTO
    @spid
WHILE @@FETCH_STATUS = 0
BEGIN
    SET @SQLCommand = 'KILL ' + CAST(@spid AS VARCHAR)
    EXECUTE(@SQLCommand)
    FETCH NEXT FROM UserCursor INTO
        @spid
END
CLOSE UserCursor
DEALLOCATE UserCursor
GO

If you want to create a generic script you can do it with an Execute statement with a Replace with your username and database name

Declare @userName as varchar(50); 
Declare @defaultDataBaseName as varchar(50);
Declare @LoginCreationScript as varchar(max);
Declare @UserCreationScript as varchar(max);
Declare @TempUserCreationScript as varchar(max);
set @defaultDataBaseName = 'data1';
set @userName = 'domain\userName';
set @LoginCreationScript ='CREATE LOGIN [{userName}]
FROM WINDOWS 
WITH DEFAULT_DATABASE ={dataBaseName}'

set @UserCreationScript ='
USE {dataBaseName}
CREATE User [{userName}] for LOGIN [{userName}];
EXEC sp_addrolemember ''db_datareader'', ''{userName}'';
EXEC sp_addrolemember ''db_datawriter'', ''{userName}'';
Grant Execute on Schema :: dbo TO [{userName}];'
/*Login creation*/
set @LoginCreationScript=Replace(Replace(@LoginCreationScript, '{userName}', @userName), '{dataBaseName}', @defaultDataBaseName)
set @UserCreationScript =Replace(@UserCreationScript, '{userName}', @userName)
Execute(@LoginCreationScript)

/*User creation and role assignment*/
set @TempUserCreationScript =Replace(@UserCreationScript, '{dataBaseName}', @defaultDataBaseName)
Execute(@TempUserCreationScript)
set @TempUserCreationScript =Replace(@UserCreationScript, '{dataBaseName}', 'db2')
Execute(@TempUserCreationScript)
set @TempUserCreationScript =Replace(@UserCreationScript, '{dataBaseName}', 'db3')
Execute(@TempUserCreationScript)

First, you need to create your branch locally

git checkout -b your_branch

After that, you can work locally in your branch, when you are ready to share the branch, push it. The next command push the branch to the remote repository origin and tracks it

git push -u origin your_branch

Your Teammates/colleagues can push to your branch by doing commits and then push explicitly

... work ...
git commit
... work ...
git commit
git push origin HEAD:refs/heads/your_branch 

Just add click event by jquery in $(document).ready() like :

$(document).ready(function(){

                  $('#YourControlID').click(function(){
                     if(Check your condtion)
                     {
                             $.messager.show({  
                                title:'My Title',  
                                msg:'The message content',  
                                showType:'fade',  
                                style:{  
                                    right:'',  
                                    bottom:''  
                                }  
                            });  
                     }
                 });
            });

One liner is best

kill -9 $(lsof -i:PORT -t) 2> /dev/null

Example : On mac, wanted to clear port 9604. Following command worked like a charm

 kill -9 $(lsof -i:9604 -t) 2> /dev/null 

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }
                .AddBody(BODY);

var response = Client.Execute(request);

// Handle response errors
HandleResponseErrors(response);

if (Errors.Length == 0)
{ }
else
{ }

Hope this helps! (Although it is a bit late)

The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.

See Best Way to Embed PDF in HTML for an overview.

There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.

nginx is useful for forwarding HTTP on many platforms including Windows. It's easy to setup and extend with more advanced configuration. A basic configuration could look something like this:

events {}

http {
     server {

        listen 192.168.1.111:4422;

        location / {
            proxy_pass http://192.168.2.33:80/;
        }
     }
}

managed to fix this by copying the below folder from another Visual Studio setup (non-express)

This was inspired by using Sets as indexers in Delphi, way back when:

/// Example of using a Boolean indexed property
/// to manipulate a [Flags] enum:

public class BindingFlagsIndexer
{
  BindingFlags flags = BindingFlags.Default;

  public BindingFlagsIndexer()
  {
  }

  public BindingFlagsIndexer( BindingFlags value )
  {
     this.flags = value;
  }

  public bool this[BindingFlags index]
  {
    get
    {
      return (this.flags & index) == index;
    }
    set( bool value )
    {
      if( value )
        this.flags |= index;
      else
        this.flags &= ~index;
    }
  }

  public BindingFlags Value 
  {
    get
    { 
      return flags;
    } 
    set( BindingFlags value ) 
    {
      this.flags = value;
    }
  }

  public static implicit operator BindingFlags( BindingFlagsIndexer src )
  {
     return src != null ? src.Value : BindingFlags.Default;
  }

  public static implicit operator BindingFlagsIndexer( BindingFlags src )
  {
     return new BindingFlagsIndexer( src );
  }

}

public static class Class1
{
  public static void Example()
  {
    BindingFlagsIndexer myFlags = new BindingFlagsIndexer();

    // Sets the flag(s) passed as the indexer:

    myFlags[BindingFlags.ExactBinding] = true;

    // Indexer can specify multiple flags at once:

    myFlags[BindingFlags.Instance | BindingFlags.Static] = true;

    // Get boolean indicating if specified flag(s) are set:

    bool flatten = myFlags[BindingFlags.FlattenHierarchy];

    // use | to test if multiple flags are set:

    bool isProtected = ! myFlags[BindingFlags.Public | BindingFlags.NonPublic];

If you use SSH version, you will not have any problems with passwords.Only one time you generate SSH key, to tell git, that this pc will work with this github account and never ask me again about any access (for this pc).

Maybe you can script/control winscp?

Update: winscp now has a .NET library available as a nuget package that supports SFTP, SCP, and FTPS

You will need the child to store the parents this variable. As the Parent is the only object that has access to it's this variable it will also need a function that places the this variable into the child's that variable, something like this.

var Parent = {
  Child : {
    that : {},
  },
  init : function(){
    this.Child.that = this;
  }
}

To test this out try to run this in Firefox's Scratchpad, it worked for me.

var Parent = {
  data : "Parent Data",

  Child : {
    that : {},
    data : "Child Data",
    display : function(){
      console.log(this.data);
      console.log(this.that.data);
    }
  },
  init : function(){
    this.Child.that = this;
  }
}

Parent.init();
Parent.Child.display();

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

Back-button text is taken from parent view-controller's navigation item title. So whatever you set on previous view-controller's navigation item title, will be shown on current view controller's back button text. You can just put "" as navigation item title in parent view-controller's viewWillAppear method.

self.navigationItem.title = ""

Another way is to put

self.navigationController?.navigationBar.topItem?.title = ""

in current view controller's viewWillAppear method. This one will cause some other problem if navigation stack is too nested.

You can try the following methods:

1. If you have a single word or one line sentence, then the following code can do the trick.

   Have a text inside a div tag and give it an id. Define the following properties for that id.

   id-name {
     height: 90px;
     line-height: 90px;
     text-align: center;
     border: 2px dashed red;
   }
   

   Note: Make sure the line-height property is same as the height of the division.

   Image

   But, if the content is more than one single word or a line then this doesn’t work. Also, there will be times when you cannot specify the size of a division in px or % (when the division is really small and you want the content to be exactly in the middle).

2. To solve this issue, we can try the following combination of properties.

   id-name {
     display: flex;
     justify-content: center;
     align-items: center;
     border: 2px dashed red;
   }
   

   Image

   These 3 lines of code sets the content exactly in the middle of a division (irrespective of the size of the display). The "align-items: center" helps in vertical centering while "justify-content: center" will make it horizontally centered.

   Note: Flex does not work in all browsers. Make sure you add appropriate vendor prefixes for additional browser support.

["some", "thing"] + ["another", "thing"]

If you need just one character and you don't want to keep things in the buffer, you can simply read a whole line and drop everything that isn't needed.

Replace:

stdin.read(1)

with

stdin.readline().strip()[:1]

This will read a line, remove spaces and newlines and just keep the first character.

I have done this before, I think you need to remove the ActionResult. Make it a void and remove the return View(MyView). this is the solution

As a humble beginner in the world of programming, and flicking through all the answers here after seeing this word used a lot in apparently slightly different ways in different places, I found reading the Wikipedia page on Bootstrapping (duh! I didn't think of it either at first) is very informative to understand differences in use of this word. Could it be......on extremely rare occasions......Wikipedia might even have better explanations of certain terms than....(redacted)? Will they bring in rep points on Wikipedia though?

To me, it seems all the meanings something to do with: start with something as simple as possible Thing1, make something slightly more complex with that Thing2, and now you can use Thing2 to do some kind of tasks more efficiently and quickly than you could originally with Thing1. Then repeat from Thing2 to Thing 3 ad infinitum...

I see it as closely connected to both biological evolution and 'Layers of Abstraction' (newbies like me see, ahem, Wikipedia, cough) - the evolution from 1940's computers with switches, machine code, Assembly, C, Python, AIs you can give all kinds of complex instructions to like "make the %4^% dinner to my default &^$% requirements and clean the floor you %$£"@:~" in drunken slang English or Amazon tribal dialect without them 'raising an exception' (for newbies again...you guessed it) - missed out lot of links there due to simple ignorance.

Then in certain specific software meanings: Meaning1: Thing1 is used to load latest version of Thing2 (because of course Thing2 will be bigger than Thing1, just as Thing3 will be be bigger than Thing2).

Meaning2: Thing1 is a lower level language (closer to 1001011100....011001 than print("Hello, ", user.name)) used to write a little bit of the higher language of Thing2, then this little bit of Thing2 is used to expand Thing2 itself from baby vocabulary level towards adult vocabulary level (Thing2 starts to be processed, or to use correct technical term 'compiled', by the baby version of itself (it's a clever baby!), whereas the baby version of Thing2 itself could of course only be compiled by Thing1, cause it can't exist before it exists, right duh!), then child version of Thing2 compiles Surly Teenager version of Thing2, at which point programming community decides whether Surly Teenager's 'issues' (software term and metaphor term!) are worth spending enough time resolving to be accepted long term, or to abandon them to (not sure where to take the analogy here).

If yes, then Thing2 has 'Bootstrapped' itself (possibly a few times) from babyhood to adulthood: "the child is the father of the man" (Wordsworth, suggest don't try looking up the quote or the author on Stack Overflow).

I had that problem too.

Try using Server.Transfer instead of Response.Redirect

Worked for me.

jot would work too (in bash shell)

To add a Visual Studio GUI reference, you can find the DropDownStyle options under the Properties of the selected ComboBox:

Which will automatically add the line mentioned in the first answer to the Form.Designer.cs InitializeComponent(), like so:

this.comboBoxBatch.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;

You get this error because pallete is full. What you need to do is override preset color. Here is an example of function I'm using:

public HSSFColor setColor(HSSFWorkbook workbook, byte r,byte g, byte b){
    HSSFPalette palette = workbook.getCustomPalette();
    HSSFColor hssfColor = null;
    try {
        hssfColor= palette.findColor(r, g, b); 
        if (hssfColor == null ){
            palette.setColorAtIndex(HSSFColor.LAVENDER.index, r, g,b);
            hssfColor = palette.getColor(HSSFColor.LAVENDER.index);
        }
    } catch (Exception e) {
        logger.error(e);
    }

    return hssfColor;
}

And later use it for background color:

HSSFColor lightGray =  setColor(workbook,(byte) 0xE0, (byte)0xE0,(byte) 0xE0);
style2.setFillForegroundColor(lightGray.getIndex());
style2.setFillPattern(CellStyle.SOLID_FOREGROUND);

Using moment will be much easier in this case, You could try this:

    let days = moment(yourFirstDateString).diff(moment(yourSecondDateString), 'days');

It will give you integer value like 1,2,5,0etc so you can easily use condition check like:

if(days < 1) {

Also, one more thing is you can get more accurate result of the time difference (in decimals like 1.2,1.5,0.7etc) to get this kind of result use this syntax:

let days = moment(yourFirstDateString).diff(moment(yourSecondDateString), 'days', true);

Let me know if you have any further query

It might be easier for you to understand using Functionoids which are expressively neater and more powerful to use, see this excellent and highly recommended C++ FAQ lite, in particular, look at section 33.12 onwards, but nonetheless, read it from the start of that section to gain a grasp and understanding of it.

To answer your question:

typedef void (*foobar)() fubarfn;

void Fun(fubarfn& baz){
   fubarfn = baz;
   baz();
}

Edit:

• & means the reference address
• * means the value of what's contained at the reference address, called de-referencing

So using the reference, example below, shows that we are passing in a parameter, and directly modify it.

void FunByRef(int& iPtr){
    iPtr = 2;
}

int main(void){
    // ...
    int n;
    FunByRef(n);
    cout << n << endl; // n will have value of 2
}

For null or undefined value error, Just add this line to attributes : ,columnDefs: [ { "defaultContent": "-", "targets": "_all" } ]

Example :

oTable = $("#bigtable").dataTable({
  columnDefs: [{
    "defaultContent": "-",
    "targets": "_all"
  }]
});

The alert box will not show again, any empty values will be replaced with what you specified.

mine was strange... IntelliJ specific quirk.

I looked at my output classes and there was a folder:

x.y.z

instead of

x/y/z

but if you have certain options set in IntelliJ, in the navigator they will both look like x.y.z

so check your output folder if you're scratching your head

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

Working jsbin: http://jsbin.com/ANAYeDU/4/edit

Main bit:

function answers()
{

var element = document.getElementById("mySelect");
var elementValue = element.value;

if(elementValue == "To measure time"){
  alert("Thats correct"); 
  }
}

it also available on repository mavenCentral() ...

dependencies {
    // https://mvnrepository.com/artifact/com.android.volley/volley
    api "com.android.volley:volley:1.1.0'
}

found = False

def check():
    datafile = file('example.txt')
    for line in datafile:
        if blabla in line:
            found = True
            break
    return found

if check():
    print "true"
else:
    print "false"

Set<E> and List<E> are both used to store elements of type E. The difference is that Set is stored in unordered way and does not allow duplicate values. List is used to store elements in ordered way and it does allow duplicate values.

Set elements cannot be accessed by an index position, and List elements can be accessed with an index position.

Create a script file; write commands:

#!/bin/sh
mongo < file.js

In file.js write your mongo query:

db.collection.find({"myValue":null}).count();

to add to John's answer:

what you want to pass to the shuffle function is a deck of cards from the class deckOfCards that you've declared in main; however, the deck of cards or vector<Card> deck that you've declared in your class is private, so not accessible from outside the class. this means you'd want a getter function, something like this:

class deckOfCards
{
    private:
        vector<Card> deck;

    public:
        deckOfCards();
        static int count;
        static int next;
        void shuffle(vector<Card>& deck);
        Card dealCard();
        bool moreCards();
        vector<Card>& getDeck() {   //GETTER
            return deck;
        }
};

this will in turn allow you to call your shuffle function from main like this:

deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck.getDeck()); // shuffle the cards in the deck

however, you have more problems, specifically when calling cout. first, you're calling the dealCard function wrongly; as dealCard is a memeber function of a class, you should be calling it like this cardDeck.dealCard(); instead of this dealCard(cardDeck);.

now, we come to your second problem - print to standard output. you're trying to print your deal card, which is an object of type Card by using the following instruction:

cout << cardDeck.dealCard();// deal the cards in the deck

yet, the cout doesn't know how to print it, as it's not a standard type. this means you should overload your << operator to print whatever you want it to print when calling with a Card type.

If you are using an external style sheet, the code could look something like this:

@font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
.junebug { font-family: Junebug; font-size: 4.2em; }

And should be saved in a separate .css file (eg styles.css). If your .css file is in a location separate from the page code, the actual font file should have the same path as the .css file, NOT the .html or .php web page file. Then the web page needs something like:

<link rel="stylesheet" href="css/styles.css">

in the <head> section of your html page. In this example, the font file should be located in the css folder along with the stylesheet. After this, simply add the class="junebug" inside any tag in your html to use Junebug font in that element.

If you're putting the css in the actual web page, add the style tag in the head of the html like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

And the actual element style can either be included in the above <style> and called per element by class or id, or you can just declare the style inline with the element. By element I mean <div>, <p>, <h1> or any other element within the html that needs to use the Junebug font. With both of these options, the font file (Junebug.ttf) should be located in the same path as the html page. Of these two options, the best practice would look like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
    .junebug { font-family: Junebug; font-size: 4.2em; }
</style>

and

<h1 class="junebug">This is Junebug</h1>

And the least acceptable way would be:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

and

<h1 style="font-family: Junebug;">This is Junebug</h1>

The reason it's not good to use inline styles is best practice dictates that styles should be kept all in one place so editing is practical. This is also the main reason that I recommend using the very first option of using external style sheets. I hope this helps.

I had a lot of problems with centring and alignment until I found Flexbox as a recommendation in a guide.

A Complete Guide to Flexbox

I'll post a snippet (that works with Chrome) here for convenience:

<head>
    <style type="text/css">
        html
        {
            width: 100%;
            height: 100%;
        }

        body
        {
            display: flex;
            justify-content: center;
            align-items: center;
        }
    </style>
</head>

<body>
    This is text!
</body>

NullPointerException with JSP can also happen if:

A getter returns a non-public inner class.

This code will fail if you remove Getters's access modifier or make it private or protected.

JAVA:

package com.myPackage;
public class MyClass{ 
    //: Must be public or you will get:
    //: org.apache.jasper.JasperException: 
    //: java.lang.NullPointerException
    public class Getters{
        public String 
        myProperty(){ return(my_property); }
    };;

    //: JSP EL can only access functions:
    private Getters _get;
    public  Getters  get(){ return _get; }

    private String 
    my_property;

    public MyClass(String my_property){
        super();
        this.my_property    = my_property;
        _get = new Getters();
    };;
};;

JSP

<%@ taglib uri   ="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="com.myPackage.MyClass" %>
<%
    MyClass inst = new MyClass("[PROP_VALUE]");
    pageContext.setAttribute("my_inst", inst ); 
%><html lang="en"><body>
    ${ my_inst.get().myProperty() }
</body></html>

You have 3 options: Chrome (via Developer Tools -> Network tab), Wireshark, and Fiddler (via Log tab), however they all very basic. If you have very high volume of traffic or each frame is very large, it becomes very difficult to use them for debugging.

You can however use Fiddler with FiddlerScript to inspect WebSocket traffic in the same way you inpect HTTP traffic. Few advantages of this solution are that you can leverage many other functionalities in Fiddler, such as multiple inspectors (HexView, JSON, SyntaxView), compare packets, and find packets, etc.

Please refer to my recently written article on CodeProject, which show you how to Debug/Inspect WebSocket traffic with Fiddler (with FiddlerScript). http://www.codeproject.com/Articles/718660/Debug-Inspect-WebSocket-traffic-with-Fiddler

Make sure you're calling super() as the first thing in your constructor.

You should set this for setAuthorState method

class ManageAuthorPage extends Component {

  state = {
    author: { id: '', firstName: '', lastName: '' }
  };

  constructor(props) {
    super(props);
    this.handleAuthorChange = this.handleAuthorChange.bind(this);
  } 

  handleAuthorChange(event) {
    let {name: fieldName, value} = event.target;

    this.setState({
      [fieldName]: value
    });
  };

  render() {
    return (
      <AuthorForm
        author={this.state.author}
        onChange={this.handleAuthorChange}
      />
    );
  }
}

Another alternative based on arrow function:

class ManageAuthorPage extends Component {

  state = {
    author: { id: '', firstName: '', lastName: '' }
  };

  handleAuthorChange = (event) => {
    const {name: fieldName, value} = event.target;

    this.setState({
      [fieldName]: value
    });
  };

  render() {
    return (
      <AuthorForm
        author={this.state.author}
        onChange={this.handleAuthorChange}
      />
    );
  }
}

Late answer but, after PHP 5.3 could be so;

$array = array(1, 2, 3, 4, 5);
$array = array_values(array_filter($array, function($v) {
    return !($v == 1 || $v == 2);
}));
print_r($array);

There is very easy solution to show headers at the top of multi columns list box. Just change the property value to "true" for "columnheads" which is false by default.

After that Just mention the data range in property "rowsource" excluding header from the data range and header should be at first top row of data range then it will pick the header automatically and you header will be freezed.

if suppose you have data in range "A1:H100" and header at "A1:H1" which is the first row then your data range should be "A2:H100" which needs to mention in property "rowsource" and "columnheads" perperty value should be true
