The Windows "AT" command is very similar to cron. It is available through the command line.

I have the same today on Win7.x64, this solve it.

Right Click MyComputer > Manage > Local Users and Groups > Groups > Administrators double click > your name should be there, if not press add...

Here's what I found.

stop:

schtasks /end /s <machine name> /tn <task name>

start:

schtasks /run /s <machine name> /tn <task name>


C:\>schtasks /?

SCHTASKS /parameter [arguments]

    SCHTASKS /Delete /?
    SCHTASKS /Query  /?
    SCHTASKS /Change /?

• Create a console app that does what you're looking for
• Use the Windows "Scheduled Tasks" functionality to have that console app executed at the time you need it to run

That's really all you need!

Update: if you want to do this inside your app, you have several options:

• in a Windows Forms app, you could tap into the Application.Idle event and check to see whether you've reached the time in the day to call your method. This method is only called when your app isn't busy with other stuff. A quick check to see if your target time has been reached shouldn't put too much stress on your app, I think...
• in a ASP.NET web app, there are methods to "simulate" sending out scheduled events - check out this CodeProject article
• and of course, you can also just simply "roll your own" in any .NET app - check out this CodeProject article for a sample implementation

Update #2: if you want to check every 60 minutes, you could create a timer that wakes up every 60 minutes and if the time is up, it calls the method.

Something like this:

using System.Timers;

const double interval60Minutes = 60 * 60 * 1000; // milliseconds to one hour

Timer checkForTime = new Timer(interval60Minutes);
checkForTime.Elapsed += new ElapsedEventHandler(checkForTime_Elapsed);
checkForTime.Enabled = true;

and then in your event handler:

void checkForTime_Elapsed(object sender, ElapsedEventArgs e)
{
    if (timeIsReady())
    {
       SendEmail();
    }
}

The windows equivalent to a cron job is a scheduled task.

A scheduled task can be created as described by Alex and Rudu, but it can also be done command line with schtasks (if you for instance need to script it or add it to version control).

An example:

schtasks /create /tn calculate /tr calc /sc weekly /d MON /st 06:05 /ru "System"

Creates the task calculate, which starts the calculator(calc) every monday at 6:05 (should you ever need that.)

All available commands can be found here: http://technet.microsoft.com/en-us/library/cc772785%28WS.10%29.aspx

It works on windows server 2008 as well as windows server 2003.

Related with the answer by @DanielSerrano, I've been recently bit by localization of the sc.exe command, namely in Spanish. My proposal is to pin-point the line and token which holds numerical service state and interpret it, which should be much more robust:

@echo off

rem TODO: change to the desired service name
set TARGET_SERVICE=w32time

set SERVICE_STATE=
rem Surgically target third line, as some locales (such as Spanish) translated the utility's output
for /F "skip=3 tokens=3" %%i in ('""%windir%\system32\sc.exe" query "%TARGET_SERVICE%" 2>nul"') do (
  if not defined SERVICE_STATE set SERVICE_STATE=%%i
)
rem Process result
if not defined SERVICE_STATE (
  echo ERROR: could not obtain service state!
) else (
  rem NOTE: values correspond to "SERVICE_STATUS.dwCurrentState"
  rem https://msdn.microsoft.com/en-us/library/windows/desktop/ms685996(v=vs.85).aspx
  if not %SERVICE_STATE%==4 (
    echo WARNING: service is not running
    rem TODO: perform desired operation
    rem net start "%TARGET_SERVICE%"
  ) else (
    echo INFORMATION: service is running
  )
)

Tested with:

• Windows XP (32-bit) English
• Windows 10 (32-bit) Spanish
• Windows 10 (64-bit) English

Basically, I've included there a bash script named "runEvery.sh" which you can run with cron every 1 minute and pass as arguments the real command you wish to run and the frequency in seconds in which you want to run it.

something like this

* * * * * ~/bin/runEvery.sh 5 myScript.sh

One option is to write a C/C++ wrapper that executes the python script on a regular basis. Your end-user would run the C/C++ executable, which would remain running in the background, and periodically execute the python script. This may not be the best solution, and may not work if you don't know C/C++ or want to keep this 100% python. But it does seem like the most user-friendly approach, since people are used to clicking on executables. All of this assumes that python is installed on your end user's computer.

Another option is to use cron job/Task Scheduler but to put it in the installer as a script so your end user doesn't have to do it.

This works for me https://www.nuget.org/packages/ASquare.WindowsTaskScheduler/

It is nicely designed Fluent API.

//This will create Daily trigger to run every 10 minutes for a duration of 18 hours
SchedulerResponse response = WindowTaskScheduler
    .Configure()
    .CreateTask("TaskName", "C:\\Test.bat")
    .RunDaily()
    .RunEveryXMinutes(10)
    .RunDurationFor(new TimeSpan(18, 0, 0))
    .SetStartDate(new DateTime(2015, 8, 8))
    .SetStartTime(new TimeSpan(8, 0, 0))
    .Execute();

Just had the same problem here. In my case, the bat files had space " " After getting rid of spaces from filename and change into underscore, bat file worked

sample before it wont start

"x:\Update & pull.bat"

after rename

"x:\Update_and_pull.bat"

One option would be to set up a windows service and get that to call your scheduled task.

In winforms I've used Timers put don't think this would work well in ASP.NET

I use Spring Framework's feature. (spring-context jar or maven dependency).

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;


@Component
public class ScheduledTaskRunner {

    @Autowired
    @Qualifier("TempFilesCleanerExecution")
    private ScheduledTask tempDataCleanerExecution;

    @Scheduled(fixedDelay = TempFilesCleanerExecution.INTERVAL_TO_RUN_TMP_CLEAN_MS /* 1000 */)
    public void performCleanTempData() {
        tempDataCleanerExecution.execute();
    }

}

ScheduledTask is my own interface with my custom method execute, which I call as my scheduled task.

To run once, daily at 10PM you should do something like this:

0 22 * * *

Check out Quartz.NET. You can use it within a Windows service. It allows you to run a job based on a configured schedule, and it even supports a simple "cron job" syntax. I've had a lot of success with it.

Here's a quick example of its usage:

// Instantiate the Quartz.NET scheduler
var schedulerFactory = new StdSchedulerFactory();
var scheduler = schedulerFactory.GetScheduler();

// Instantiate the JobDetail object passing in the type of your
// custom job class. Your class merely needs to implement a simple
// interface with a single method called "Execute".
var job = new JobDetail("job1", "group1", typeof(MyJobClass));

// Instantiate a trigger using the basic cron syntax.
// This tells it to run at 1AM every Monday - Friday.
var trigger = new CronTrigger(
    "trigger1", "group1", "job1", "group1", "0 0 1 ? * MON-FRI");

// Add the job to the scheduler
scheduler.AddJob(job, true);
scheduler.ScheduleJob(trigger);

There isn't a "pure python" way to do this because some other process would have to launch python in order to run your solution. Every platform will have one or twenty different ways to launch processes and monitor their progress. On unix platforms, cron is the old standard. On Mac OS X there is also launchd, which combines cron-like launching with watchdog functionality that can keep your process alive if that's what you want. Once python is running, then you can use the sched module to schedule tasks.

Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET command. The first one to stop the service, the second one to start the service. Give them a STOP and START argument, followed by the service name.

In this example we restart the Printer Spooler service.

NET STOP "Print Spooler" 
NET START "Print Spooler"

Note: unfortunately NET RESTART <service name> does not exist.

Although not part of Django, Airflow is a more recent project (as of 2016) that is useful for task management.

Airflow is a workflow automation and scheduling system that can be used to author and manage data pipelines. A web-based UI provides the developer with a range of options for managing and viewing these pipelines.

Airflow is written in Python and is built using Flask.

Airflow was created by Maxime Beauchemin at Airbnb and open sourced in the spring of 2015. It joined the Apache Software Foundation’s incubation program in the winter of 2016. Here is the Git project page and some addition background information.

The >> will append the log file, rather than overwriting it each time. The 2>&1 will also send errors to your log file.

If youu are having this problem under WIN 10 this might solve your problem as it did for me. An update messed up the task scheduler.

http://answers.microsoft.com/en-us/windows/forum/windows_10-performance/anniversary-update-version-1607-build14393-breaks/d034ab52-5d49-4b92-976a-a1355b5a6e6d?page=2

This comment solved my problem.

Your tip about "one-time" tasks works great - it will definitely be sufficient as a workaround until MS fixes the issue. The only advantage to "daily" as far as I can see is that lack of the arbitrary date associated with the run time. It might be confusing to others as to why the job is set to start on X date.

Trigger settings "Einmal" means "one-time", "Sofort" means "At once"

On XP, I clicked the Advanced button on the Schedule tab. There is a checkbox for Repeat task. The default is every 10 minutes.

Additionally, you can create scheduled task via the command line. I haven't tried this myself, but it looks like you'd want something along the lines of (not tested):

schtasks /create /tn "Some task name" /tr "app.exe" /sc HOURLY 

I got the same error but I have fixed it by changing the file reading path from "ConfigFile.xml" to AppDomain.CurrentDomain.BaseDirectory.ToString() + "ConfigFile.xml"

In my case, this error due to file path error because task manager starts program from "System32" as initial path but the folder we thought.

I think the best ranking is

1.node-schedule

2.later

3.crontab

and the sample of node-schedule is below:

var schedule = require("node-schedule");
var rule = new schedule.RecurrenceRule();
//rule.minute = 40;
rule.second = 10;
var jj = schedule.scheduleJob(rule, function(){
    console.log("execute jj");
});

Maybe you can find the answer from node modules.

Another alternative might be to use Flask-APScheduler which plays nicely with Flask, e.g.:

• Loads scheduler configuration from Flask configuration,
• Loads job definitions from Flask configuration

More information here:

https://pypi.python.org/pypi/Flask-APScheduler

If you need to see the output of the execute, use CALL together with or instead of START.

Example:

CALL "C:\Program Files\Certain Directory\file.exe" -param PAUSE

This will run the file.exe and print back whatever it outputs, in the same command window. Remember the PAUSE after the call or else the window may close instantly.

I messed with this for several hours and tried many different suggestions.

I finally got it to work by doing the following:

Action: Start a program

Program/Script: C:\scriptdir\script.bat

Add arguments (optional) script.bat

Start in (optional): c:\scriptdir

run only when user logged in

run with highest privileges

configure for: Windows Vista, Windows Server 2008

For me it was the "Start In" - I copied the values from an older server, and updated the path to the new .exe location, but I forgot to update the "start in" location - if it doesn't exist, you get this error too

Quoting @hans-passant 's comment from above, because it is valuable to debugging this issue:

Convert the error code to hex to get 0x8007010B. The 7 makes it a Windows error. Which makes 010B error code 267. "The directory name is invalid". Sure, that happens.

Eduardo Molteni had a great answer:

• SQL Server Automated Backups

Using Windows Scheduled Tasks:

In the batch file

"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\SQLCMD.EXE" -S 
(local)\SQLExpress -i D:\dbbackups\SQLExpressBackups.sql

In SQLExpressBackups.sql

BACKUP DATABASE MyDataBase1 TO  DISK = N'D:\DBbackups\MyDataBase1.bak' 
WITH NOFORMAT, INIT,  NAME = N'MyDataBase1 Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

BACKUP DATABASE MyDataBase2 TO  DISK = N'D:\DBbackups\MyDataBase2.bak' 
WITH NOFORMAT, INIT,  NAME = N'MyDataBase2 Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

GO

As noted by Mattias Nordqvist in the comments below, you can also select the radio button option "Run whether user is logged on or not". When saving the task, you will be prompted once for the user password. bambams noted that this wouldn't grant System permissions to the process, and also seems to hide the command window.

It's not an obvious solution, but to make a Scheduled Task run in the background, change the User running the task to "SYSTEM", and nothing will appear on your screen.

This may help others where there is no option to Enable/Disable the history anywhere in Task Scheduler.

Open Event Viewer (either in Computer Management or Admin Tools > Event Viewer).

In Event Viewer make sure the Preview Pane is showing (View > Preview Pane should be ticked)

In the left hand pane expand Application and Service Logs then Microsoft, Windows, TaskScheduler and then select Operational.

You should have Actions showing in the preview pane with two sections - Operational and below that Event nnn, TaskScheduler. One of the items listed in the Operational section should be Properties. Click this item and the Enable Logging option is on the General tab.

My problem was that the maximum log size had been reached and even though the overwrite old events option was selected it wasn't logging new events. I suspect that might have been a permissions issue but I changed it to Archive when full and all is now working again.

Hope this helps someone else out there. If you don't have the options I've mentioned above I'm sorry, but I don't know where you should look.

There are multiple issues with the MMC however as on almost every PC in my business the ask scheduler API will not open and has somehow been corrupted. So you cannot edit, delete or otherwise modify tasks that were developed before the API decided not to run anymore. The only way we have found to fix that issue is to totally wipe away a persons profile under the C:\Users\ area and force the system to recreate the log in once the person logs back in. This seems to fix the API issue and it works again, however the tasks are often not visible anymore to that user since the tasks developed are specific to the user and not the machine in Windows 7. The other odd thing is that sometimes, although not with any frequency that can be analyzed, the tasks still run even though the API is corrupted and will not open. The cause of this issue is apparently not known but there are many "fixes" described on various websites, but the user profile deletion and adding anew seems to work every time for at least a little while. The tasks are saved as XML now in WIN 7, so if you do find them in the system32/tasks folder you can delete them, or copy them to a new drive and then import them back into task scheduler. We went with the system scheduler software from Splinterware though since we had the same corruption issue multiple times even with the fix that does not seem to be permanent.

On properties,

Check whether radio button is selected for

Run only when user is logged on 

If you selected for the above option then that is the reason why it is failed.

so change the option to

Run whether user is logged on or not

OR

In other case, user might have changed his/her login credentials

My reason for sometimes preferring Timer over Executors.newSingleThreadScheduledExecutor() is that I get much cleaner code when I need the timer to execute on daemon threads.

compare

private final ThreadFactory threadFactory = new ThreadFactory() {
    public Thread newThread(Runnable r) {
        Thread t = new Thread(r);
        t.setDaemon(true);
        return t;
    }
};
private final ScheduledExecutorService timer = Executors.newSingleThreadScheduledExecutor(threadFactory); 

with

private final Timer timer = new Timer(true);

I do this when I don't need the robustness of an executorservice.

This is a pretty old thread but the problem is still the same -

I tried multiple things, none of them worked -

1. Added a Start In Path (without quotes)
2. Removed the complete path of the batch file in the Program/Script field etc
3. Added C:\Windows\system32\cmd.exe to the Program and added /c myscript.bat to the arguments field.

This is what worked for me -

Program/Script Field - cmd

Add Arguments - /c myscript.bat

Start In : Path to myscript.bat

To Calculate days between 2 given dates you can use the following code.Dates I use here are Jan 01 2016 and Dec 31 2016

var day_start = new Date("Jan 01 2016");_x000D_
var day_end = new Date("Dec 31 2016");_x000D_
var total_days = (day_end - day_start) / (1000 * 60 * 60 * 24);_x000D_
document.getElementById("demo").innerHTML = Math.round(total_days);

<h3>DAYS BETWEEN GIVEN DATES</h3>_x000D_
<p id="demo"></p>

For some odd reason this DID NOT work (using Pandas: '0.25.1')

df[['col1', 'col2']].fillna(value=0, inplace=True)

Another solution:

subset_cols = ['col1','col2']
[df[col].fillna(0, inplace=True) for col in subset_cols]

Example:

df = pd.DataFrame(data={'col1':[1,2,np.nan,], 'col2':[1,np.nan,3], 'col3':[np.nan,2,3]})

output:

   col1  col2  col3
0  1.00  1.00   nan
1  2.00   nan  2.00
2   nan  3.00  3.00

Apply list comp. to fillna values:

subset_cols = ['col1','col2']
[df[col].fillna(0, inplace=True) for col in subset_cols]

Output:

   col1  col2  col3
0  1.00  1.00   nan
1  2.00  0.00  2.00
2  0.00  3.00  3.00

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

if (typeof jQuery == 'undefined')) { ...

Or

if(!window.jQuery){

Will not works if cdn version not loaded, because browser will run through this condition and during it still downloading the rest of javascripts which needs jQuery and it returns error. Solution was to load scripts through that condition.

    <script src="http://WRONGPATH.code.jquery.com/jquery-1.4.2.min.js" type="text/javascript"></script><!--  WRONGPATH for test-->
  <script type="text/javascript">
  function loadCDN_or_local(){
    if(!window.jQuery){//jQuery not loaded, take a local copy of jQuery and then my scripts
      var scripts=['local_copy_jquery.js','my_javascripts.js'];
      for(var i=0;i<scripts.length;i++){
      scri=document.getElementsByTagName('head')[0].appendChild(document.createElement('script'));
      scri.type='text/javascript';
      scri.src=scripts[i];
    }
  }
  else{// jQuery loaded can load my scripts
    var s=document.getElementsByTagName('head')[0].appendChild(document.createElement('script'));
    s.type='text/javascript';
    s.src='my_javascripts.js';
  }
  }
  window.onload=function(){loadCDN_or_local();};
  </script>

As far as I know, there isn't any better way in terms of working with Reflection library in a smarter way. However, you could use LINQ to make the code a bit nicer:

var props = from p in t.GetProperties()
            let attrs = p.GetCustomAttributes(typeof(MyAttribute), true)
            where attrs.Length != 0 select p;

// Do something with the properties in 'props'

I believe this helps you to structure the code in a more readable fashion.

use this code 100% fix your problem

enter this code in firstFragment

public static yourNameParentFragment newInstance() {

    Bundle args = new Bundle();
    args.putBoolean("yourKey",yourValue);
    YourFragment fragment = new YourFragment();
    fragment.setArguments(args);
    return fragment;
}

this sample send boolean data

and in SecendFragment

yourNameParentFragment name =yourNameParentFragment.newInstance();
   Bundle bundle;
   bundle=sellDiamondFragments2.getArguments();
  boolean a= bundle.getBoolean("yourKey");

must value in first fragment is static

happy code

The compiler only knows that the type of "a" is Animal; this happens at compile time, because of which it is called static binding (Method overloading). But if it is dynamic binding then it would call the Dog class method. Here is an example of dynamic binding.

public class DynamicBindingTest {

    public static void main(String args[]) {
        Animal a= new Dog(); //here Type is Animal but object will be Dog
        a.eat();       //Dog's eat called because eat() is overridden method
    }
}

class Animal {

    public void eat() {
        System.out.println("Inside eat method of Animal");
    }
}

class Dog extends Animal {

    @Override
    public void eat() {
        System.out.println("Inside eat method of Dog");
    }
}

Output: Inside eat method of Dog

I just had a same issue of none of my console message showing. It was simply because I was using the new Edge (Chromium based) browser on Windows 10. It does not show my console messages whereas Chrome does. I guessed it was an issue with Edge because I had another odd issue with Edge because it treated strings with single quotes and double quotes differently.

Please note this doesn't solve the cookie sharing process, as in general this is bad practice.

You need to be using JSONP as your type:

From $.ajax documentation: Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation.

$.ajax(
    { 
      type: "POST",
      url: "http://example.com/api/getlist.json",
      dataType: 'jsonp',
      xhrFields: {
           withCredentials: true
      },
      crossDomain: true,
      beforeSend: function(xhr) {
            xhr.setRequestHeader("Cookie", "session=xxxyyyzzz");
      },
      success: function(){
           alert('success');
      },
      error: function (xhr) {
             alert(xhr.responseText);
      }
    }
);

In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.

This is normally more an issue with ToMany than ToOnes. For example,

Select e from Employee e 
join fetch e.phones p 
where p.areaCode = '613'

This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.

Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.

The Android Developer pages still state how you can download and use the ADT plugin for Eclipse:

1. Start Eclipse, then select Help > Install New Software.
2. Click Add, in the top-right corner.
3. In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location: https://dl-ssl.google.com/android/eclipse/
4. Click OK.
5. In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
6. In the next window, you'll see a list of the tools to be downloaded. Click Next.
7. Read and accept the license agreements, then click Finish. If you get a security warning saying that the authenticity or validity of the software can't be established, click OK
8. When the installation completes, restart Eclipse.

Links for the Eclipse ADT Bundle (found using Archive.org's WayBackMachine) I don't know how future-proof these links are. They all worked on February 27th, 2017.

• Windows x86-64
• Windows x86
• Mac OS x86-64
• Linux x86

Update (2015-06-29): Google will end development and official support for ADT in Eclipse at the end of this year and recommends switching to Android Studio.

I have used graphviz ( https://www.graphviz.org/gallery ) together with LaTeX using dot command to generate graphs in PDF and includegraphics to include those.

If graphviz produces what you are aiming at, this might be the best way to integrate: dot2tex: https://ctan.org/pkg/dot2tex?lang=en

Given a staging table with 70 columns and only 4 representing duplicates, this code will return the offending columns:

SELECT 
    COUNT(*)
    ,LTRIM(RTRIM(S.TransactionDate)) 
    ,LTRIM(RTRIM(S.TransactionTime))
    ,LTRIM(RTRIM(S.TransactionTicketNumber)) 
    ,LTRIM(RTRIM(GrossCost)) 
FROM Staging.dbo.Stage S
GROUP BY 
    LTRIM(RTRIM(S.TransactionDate)) 
    ,LTRIM(RTRIM(S.TransactionTime))
    ,LTRIM(RTRIM(S.TransactionTicketNumber)) 
    ,LTRIM(RTRIM(GrossCost)) 
HAVING COUNT(*) > 1

.

you can use PATTERN:

<input class="form-control" minlength="1" pattern="[0-9]*" [(ngModel)]="value" #name="ngModel">

<div *ngIf="name.invalid && (name.dirty || name.touched)" class="text-danger">
  <div *ngIf="name.errors?.pattern">Is not a number</div>
</div>

You should explicitly specify the second parameter (sheetname) as None. like this:

 df = pandas.read_excel("/yourPath/FileName.xlsx", None);

"df" are all sheets as a dictionary of DataFrames, you can verify it by run this:

df.keys()

result like this:

[u'201610', u'201601', u'201701', u'201702', u'201703', u'201704', u'201705', u'201706', u'201612', u'fund', u'201603', u'201602', u'201605', u'201607', u'201606', u'201608', u'201512', u'201611', u'201604']

please refer pandas doc for more details: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_excel.html

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

It made a lot more sense to add this as an answer to arin's code than to keep doing it in comments...

1) Consider using decimal instead of double. It's more likely to give the answer the user expects. See http://pobox.com/~skeet/csharp/floatingpoint.html and http://pobox.com/~skeet/csharp/decimal.html for reasons why. Basically decimal works a lot closer to how humans think about numbers than double does. Double works more like how computers "naturally" think about numbers, which is why it's faster - but that's not relevant here.

2) For user input, it's usually worth using a method which doesn't throw an exception on bad input - e.g. decimal.TryParse and int.TryParse. These return a Boolean value to say whether or not the parse succeeded, and use an out parameter to give the result. If you haven't started learning about out parameters yet, it might be worth ignoring this point for the moment.

3) It's only a little point, but I think it's wise to have braces round all "for"/"if" (etc) bodies, so I'd change this:

for (int counter = 0; counter < 6; counter++)
    Console.WriteLine("{0,5}{1,8}", counter, array[counter]);

to this:

for (int counter = 0; counter < 6; counter++)
{
    Console.WriteLine("{0,5}{1,8}", counter, array[counter]);
}

It makes the block clearer, and means you don't accidentally write:

for (int counter = 0; counter < 6; counter++)
    Console.WriteLine("{0,5}{1,8}", counter, array[counter]);
    Console.WriteLine("----"); // This isn't part of the for loop!

4) Your switch statement doesn't have a default case - so if the user types anything other than "yes" or "no" it will just ignore them and quit. You might want to have something like:

bool keepGoing = true;
while (keepGoing)
{
    switch (answer)
    {
        case "yes":
            Console.WriteLine("===============================================");
            Console.WriteLine("please enter the array index you wish to get the value of it");
            int index = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("===============================================");
            Console.WriteLine("The Value of the selected index is:");
            Console.WriteLine(array[index]);
            keepGoing = false;
            break;

        case "no":
            Console.WriteLine("===============================================");
            Console.WriteLine("HAVE A NICE DAY SIR");
            keepGoing = false;
            break;

        default:
            Console.WriteLine("Sorry, I didn't understand that. Please enter yes or no");
            break;
    }
}

5) When you've started learning about LINQ, you might want to come back to this and replace your for loop which sums the input as just:

// Or decimal, of course, if you've made the earlier selected change
double sum = input.Sum();

Again, this is fairly advanced - don't worry about it for now!

I was having a similar issue like yours, except that I wanted a specific subset of 'ancestry'. Hong Ning's query was a good start, except it will return combined records containing duplicates and/or extra ancestries (e.g. it would also return someone with ancestries ('England', 'France', 'Germany', 'Netherlands') and ('England', 'France', 'England'). Supposing you'd want just the three and only the three, you'd need the following query:

SELECT Src.user_id
FROM yourtable Src
WHERE ancestry in ('England', 'France', 'Germany')
    AND EXISTS (
        SELECT user_id
        FROM dbo.yourtable
        WHERE user_id = Src.user_id
        GROUP BY user_id
        HAVING COUNT(DISTINCT ancestry) = 3
        )
GROUP BY user_id
HAVING COUNT(DISTINCT ancestry) = 3

My answer
Use nested for loops to provide break points to the for /l loop.

for %%a in (0 1 2 3 4 5 6 7 8 9) do (
   for %%b in (0 1 2 3 4 5 6 7 8 9) do (
      for /l %%c in (1,1,10) do (
         if not exist %%a%%b%%c goto :continue
      )
   )
)
:continue

Explanation The code must be tweaked significantly to properly use the nested loops. For example, what is written will have leading zeros.
"Regular" for loops can be immediately broken out of with a simple goto command, where for /l loops cannot. This code's innermost for /l loop cannot be immediately broken, but an overall break point is present after every 10 iterations (as written). The innermost loop doesn't have to be 10 iterations -- you'll just have to account for the math properly if you choose to do 100 or 1000 or 2873 for that matter (if math even matters to the loop).

History I found this question while trying to figure out why a certain script was running slowly. It turns out I used multiple loops with a traditional loop structure:

set cnt=1
:loop
if "%somecriteria%"=="finished" goto :continue
rem do some things here
set /a cnt += 1
goto :loop

:continue
echo the loop ran %cnt% times

This script file had become somewhat long and it was being run from a network drive. This type of loop file was called maybe 20 times and each time it would loop 50-100 times. The script file was taking too long to run. I had the bright idea of attempting to convert it to a for /l loop. The number of needed iterations is unknown, but less than 10000. My first attempt was this:

setlocal enabledelayedexpansion
set cnt=1
for /l %%a in (1,1,10000) do (
   if "!somecriteria!"=="finished" goto :continue
   rem do some things here
   set /a cnt += 1
)

:continue
echo the loop ran %cnt% times

With echo on, I quickly found out that the for /l loop still did ... something ... without actually doing anything. It ran much faster, but still slower than I thought it could/should. Therefore I found this question and ended up with the nested loop idea presented above.

Side note It turns out that the for /l loop can be sped up quite a bit by simply making sure it doesn't have any output. I was able to do this for a noticeable speed increase:

setlocal enabledelayedexpansion
set cnt=1
@for /l %%a in (1,1,10000) do @(
   if "!somecriteria!"=="finished" goto :continue
   rem do some things here
   set /a cnt += 1
) > nul

:continue
echo the loop ran %cnt% times

I am too late, but you can try this approach as well.

#include <stdio.h>
#include <stdlib.h>

int main() {
    int i=0, j=0, arr[100];
    char temp;
    while(scanf("%d%c", &arr[i], &temp)){
        i++;
        if(temp=='\n'){
            break;
        }
    }
    for(j=0; j<i; j++) {
        printf("%d ", arr[j]);
    }

    return 0;
}

You can also try to use get(), for example:

connection = manager.connect.get("I2Cx")

which won't raise a KeyError in case the key doesn't exist.

You may also use second argument to specify the default value, if the key is not present.

I am surprised that such a basic question doesn't seem to have an immediate answer in python. It seems to me that nearly all proposed answers use some kind of type checking, that is usually not advised in python and they seem restricted to a specific case (they fail with different numerical types or generic iteratable objects that are not tuples or lists).

For me, what works better is importing numpy and using array.size, for example:

>>> a=1
>>> np.array(a)
Out[1]: array(1)

>>> np.array(a).size
Out[2]: 1

>>> np.array([1,2]).size
Out[3]: 2

>>> np.array('125')
Out[4]: 1

Note also:

>>> len(np.array([1,2]))

Out[5]: 2

but:

>>> len(np.array(a))
---------------------------------------------------------------------------

Not for blanks in the middle of a range, but this works for a complex chart from a start date until infinity (ie no need to adjust the chart's data source each time informatiom is added), without showing any lines for dates that have not yet been entered. As you add dates and data to the spreadsheet, the chart expands. Without it, the chart has a brain hemorrhage.

So, to count a complex range of conditions over an extended period of time but only if the date of the events is not blank :

=IF($B6<>"",(COUNTIF($O6:$O6,Q$5)),"") returns “#N/A” if there is no date in column B.

In other words, "count apples or oranges or whatever in column O (as determined by what is in Q5) but only if column B (the dates) is not blank". By returning “#N/A”, the chart will skip the "blank" rows (blank as in a zero value or rather "#N/A").

From that table of returned values you can make a chart from a date in the past to infinity

Here is a solution if you need to hook up some methods to @User for use in your views. No solution for any serious membership customization, but if the original question was needed for views alone then this perhaps would be enough. The below was used for checking a variable returned from a authorizefilter, used to verify if some links wehere to be presented or not(not for any kind of authorization logic or access granting).

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Security.Principal;

    namespace SomeSite.Web.Helpers
    {
        public static class UserHelpers
        {
            public static bool IsEditor(this IPrincipal user)
            {
                return null; //Do some stuff
            }
        }
    }

Then just add a reference in the areas web.config, and call it like below in the view.

Often an application needs to execute different functions based upon its context/state. For this, we use a variable where we would store the information about the function to be called. ?According to its need the application will set this variable with the information about function to be called and will call the function using the same variable.

In javascript, the example is below. Here we use method argument as a variable where we store information about function.

function processArray(arr, callback) {
    var resultArr = new Array(); 
    for (var i = arr.length-1; i >= 0; i--)
        resultArr[i] = callback(arr[i]);
    return resultArr;
}

var arr = [1, 2, 3, 4];
var arrReturned = processArray(arr, function(arg) {return arg * -1;});
// arrReturned would be [-1, -2, -3, -4]

.Split(new string[] { "is Marco and" }, StringSplitOptions.None)

Having the problem that the new TabLayout uses the indicator color from the value colorAccent, I decided to dig into the android.support.design.widget.TabLayout implementation, finding that there are no public methods to customize this. However I found this style specification of the TabLayout:

<style name="Base.Widget.Design.TabLayout" parent="android:Widget">
    <item name="tabMaxWidth">@dimen/tab_max_width</item>
    <item name="tabIndicatorColor">?attr/colorAccent</item>
    <item name="tabIndicatorHeight">2dp</item>
    <item name="tabPaddingStart">12dp</item>
    <item name="tabPaddingEnd">12dp</item>
    <item name="tabBackground">?attr/selectableItemBackground</item>
    <item name="tabTextAppearance">@style/TextAppearance.Design.Tab</item>
    <item name="tabSelectedTextColor">?android:textColorPrimary</item>
</style>

Having this style specification, now we can customize the TabLayout like this:

<android.support.design.widget.TabLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@id/pages_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:tabIndicatorColor="@android:color/white"
    app:tabIndicatorHeight="4dp"/>

And problem solved, both the tab indicator color and height can be changed from their default values.

This will give you what you want:

eg2011cleaned <- eg2011[!eg2011$ID %in% bg2011missingFromBeg, ]

The error in your second attempt is because you forgot the ,

In general, for convenience, the specification object[index] subsets columns for a 2d object. If you want to subset rows and keep all columns you have to use the specification object[index_rows, index_columns], while index_cols can be left blank, which will use all columns by default.

However, you still need to include the , to indicate that you want to get a subset of rows instead of a subset of columns.

I have 4 ships to set on one single map, so I use the Google Developers example and then twisted it

    url: 'img/bullet_amarelo.png',
    // This marker is 20 pixels wide by 32 pixels tall.

    // The origin for this image is 0,0.
    origin: new google.maps.Point(0,0),
    // The anchor for this image is the base of the flagpole at 0,32.

          // This marker is 20 pixels wide by 32 pixels tall.
          size: new google.maps.Size(40, 40),
          // The origin for this image is 0,0.
          origin: new google.maps.Point(0,0),
          // The anchor for this image is the base of the flagpole at 0,32.
          anchor: new google.maps.Point(0, 40)
        };
...
}

And in the FOR bellow I set one color for each ship:

for (var i = 0; i < locations.length; i++) {
...
    if (i==0) var imageV=image;
    if (i==1) var imageV=image1;
    if (i==2) var imageV=image2;
    if (i==3) var imageV=image3;
...
# remember to change icon: image to icon: imageV
}

The final result:

FILL_PARENT was renamed MATCH_PARENT in API Level 8 and higher which means that the view wants to be as big as its parent (minus padding) - Google

First scenario: DB1.sqlite and DB2.sqlite have the same table(t1), but DB1 is more "up to date" than DB2. If it's small, drop the table from DB2 and recreate it with the data:

> DROP TABLE IF EXISTS db2.t1; CREATE TABLE db2.t1 AS SELECT * FROM db1.t1;

Second scenario: If it's a large table, you may be better off with an INSERT if not exists type solution. If you have a Unique Key column it's more straight forward, otherwise you'd need to use a combination of fields (maybe every field) and at some point it's still faster to just drop and re-create the table; it's always more straight forward (less thinking required).

THE SETUP: open SQLite without a DB which creates a temporary in memory main database, then attach DB1.sqlite and DB2.sqlite

> sqlite3
sqlite> ATTACH "DB1.sqlite" AS db1
sqlite> ATTACH "DB2.sqlite" AS db2

and use .databases to see the attached databases and their files.

sqlite> .databases
main: 
db1: /db/DB1.sqlite
db2: /db/DB2.sqlite

It's either through system property

You have to add parameters since it is needed for the SP to execute

using (SqlConnection con = new SqlConnection(dc.Con))
{
    using (SqlCommand cmd = new SqlCommand("SP_ADD", con))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@FirstName", txtfirstname.Text);
        cmd.Parameters.AddWithValue("@LastName", txtlastname.Text);
        con.Open();
        cmd.ExecuteNonQuery();
    }            
}

In Oracle, you could use rownum to limit the number of rows returned. I am guessing similar construct exists in other SQLs as well. So, for the example you gave, you could limit the number of rows returned to 500001 and apply a count(*) then:

SELECT (case when cnt > 500000 then 500000 else cnt end) myCnt
FROM (SELECT count(*) cnt FROM table WHERE rownum<=500001)

I do not know if your still looking for the answer to this problem but today I happened the same problem and solved it. You need to specify in the HTML code,

**<Div class = "navbar"**>
         div class = "container">
               <Div class = "navbar-header">

or

**<Div class = "navbar navbar-default">**
        div class = "container">
               <Div class = "navbar-header">

You got that place in your CSS

.navbar-default-toggle .navbar .icon-bar {
  background-color: # 0000ff;
}

and what I did was add above

.navbar .navbar-toggle .icon-bar {
  background-color: # ff0000;
}

Because my html code is

**<Div class = "navbar">**
         div class = "container">
               <Div class = "navbar-header">

and if you associate a file less / css

search this section and also here placed the color you want to change, otherwise it will self-correct the css file to the state it was before

// Toggle Navbar
@ Navbar-default-toggle-hover-bg: #ddd;
**@ Navbar-default-toggle-icon-bar-bg: # 888;**
@ Navbar-default-toggle-border-color: #ddd;

if your html code is like mine and is not navbar-default, add it as you did with the css.

// Toggle Navbar
@ Navbar-default-toggle-hover-bg: #ddd;
**@ Navbar-toggle-icon-bar-bg : #888;**
@ Navbar-default-toggle-icon-bar-bg: # 888;
@ Navbar-default-toggle-border-color: #ddd;

good luck

One way to solve this problem is to get the starting points from the values themselves:

var minLen, maxLen uint
if len(sliceOfThings) > 0 {
  minLen = sliceOfThings[0].minLen
  maxLen = sliceOfThings[0].maxLen
  for _, thing := range sliceOfThings[1:] {
    if minLen > thing.minLen { minLen = thing.minLen }
    if maxLen < thing.maxLen { maxLen = thing.maxLen }
  }
}

How about

<img style="display: none;" src="a.gif">

That will disable the display completely, and not leave a placeholder

Here is a pretty good solution to makes only allow enter number to the input:

<input type="text" ng-model="myText" name="inputName" onkeypress='return event.charCode >= 48 && event.charCode <= 57'/>

Try this:

pointer-events:none

Adding above on the specified HTML element will prevents all click, state and cursor options.

http://jsfiddle.net/4hrpsrnp/

<div class="ads">
 <button id='noclick' onclick='clicked()'>Try</button>
</div>

I know this question is 8 year old, however there was and is a better solution for this purpose. It's always been there, and still is: User32.dll!MessageBoxTimeout.

This is an undocumented function used by Microsoft Windows, and it does exactly what you want and even more. It supports different languages as well.

C# Import:

[DllImport("user32.dll", SetLastError = true)]
public static extern int MessageBoxTimeout(IntPtr hWnd, String lpText, String lpCaption, uint uType, Int16 wLanguageId, Int32 dwMilliseconds);

[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr GetForegroundWindow();

How to use it in C#:

uint uiFlags = /*MB_OK*/ 0x00000000 | /*MB_SETFOREGROUND*/  0x00010000 | /*MB_SYSTEMMODAL*/ 0x00001000 | /*MB_ICONEXCLAMATION*/ 0x00000030;

NativeFunctions.MessageBoxTimeout(NativeFunctions.GetForegroundWindow(), $"Kitty", $"Hello", uiFlags, 0, 5000);

Work smarter, not harder.

I assume you're talking about the Apache server that Oracle installs. Look for the file httpd.conf.

Open this file in a text editor and look for the line
Listen 8080
or
Listen {ip address}:8080

Change the port number and either restart the web server or just reboot the machine.

If are you working with numbers a lot, you might want to take a look at NumPy. It lets you perform all kinds of operation directly on numerical arrays. For example:

>>> import numpy
>>> array = numpy.array([49, 51, 53, 56])
>>> array - 13
array([36, 38, 40, 43])

First, you don't declare the type in Ruby, so you don't need the first string.

To replace a word in string, you do: sentence.gsub(/match/, "replacement").

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

you may consider this answer as enhancement .. usually I am using

tail -F <fileName> | grep --line-buffered  <pattern> -A 3 -B 5

-F is better in case of file rotate (-f will not work properly if file rotated)

-A and -B is useful to get lines just before and after the pattern occurrence .. these blocks will appeared between dashed line separators

But For me I prefer doing the following

tail -F <file> | less

this is very useful if you want to search inside streamed logs. I mean go back and forward and look deeply

Here is what I'm using:

if (mySQLConnection.State != ConnectionState.Open)
{
    mySQLConnection.Close();
    mySQLConnection.Open();
}

The reason I'm not simply using:

if (mySQLConnection.State == ConnectionState.Closed)
{
    mySQLConnection.Open();
}

Is because the ConnectionState can also be:

Broken, Connnecting, Executing, Fetching

In addition to

Open, Closed

Additionally Microsoft states that Closing, and then Re-opening the connection "will refresh the value of State." See here http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.state(v=vs.110).aspx

To use multiple files from node_modules in html, the best way I've found is to put them to an array and then loop on them to make them visible for web clients, for example to use filepond modules from node_modules:

const filePondModules = ['filepond-plugin-file-encode', 'filepond-plugin-image-preview', 'filepond-plugin-image-resize', 'filepond']
filePondModules.forEach(currentModule => {
    let module_dir = require.resolve(currentModule)
                           .match(/.*\/node_modules\/[^/]+\//)[0];
    app.use('/' + currentModule, express.static(module_dir + 'dist/'));
})

And then in the html (or layout) file, just call them like this :

    <link rel="stylesheet" href="/filepond/filepond.css">
    <link rel="stylesheet" href="/filepond-plugin-image-preview/filepond-plugin-image-preview.css">
...
    <script src="/filepond-plugin-image-preview/filepond-plugin-image-preview.js" ></script>
    <script src="/filepond-plugin-file-encode/filepond-plugin-file-encode.js"></script>
    <script src="/filepond-plugin-image-resize/filepond-plugin-image-resize.js"></script>
    <script src="/filepond/filepond.js"></script>

In CSS3 paged media this is possible using position: running() and content: element().

Example from the CSS Generated Content for Paged Media Module draft:

@top-center {
  content: element(heading); 
}

.runner { 
  position: running(heading);
}

.runner can be any element and heading is an arbitrary name for the slot.

EDIT: to clarify, there is basically no browser support so this was mostly meant to be for future reference/in addition to the 'practical answers' given already.

For any one who has a problem with airflow linked to this issue.

In my case, I've initialized airflow in /root/airflow and run its scheduler as root. I used the run_as_user parameter to impersonate the web user while running task instances. However airflow was always failing to trigger my DAG with the following errors in logs:

sqlite3.OperationalError: unable to open database file
...
sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) unable to open database file

I also found once I triggered a DAG manually, a new airflow resource directory was automatically created under /home/web. I'm not clear about this behavior, but I make it work by removing the entire airflow resources from /root, reinitializing airflow database under /home/web and running the scheduler as web under:

[root@host ~]# rm -rf airflow
[web@host ~]$ airflow initdb
[web@host ~]$ airflow scheduler -D

If you want to try this approach, I may need to backup your data before doing anything.

You can get the spark version by using the following command:

spark-submit --version

spark-shell --version

spark-sql --version

You can visit the below site to know the spark-version used in CDH 5.7.0

For those of us using Windows, look at this:

Reference: http://php.net/manual/en/function.exec.php#43917

I too wrestled with getting a program to run in the background in Windows while the script continues to execute. This method unlike the other solutions allows you to start any program minimized, maximized, or with no window at all. llbra@phpbrasil's solution does work but it sometimes produces an unwanted window on the desktop when you really want the task to run hidden.

start Notepad.exe minimized in the background:

<?php 
$WshShell = new COM("WScript.Shell"); 
$oExec = $WshShell->Run("notepad.exe", 7, false); 
?> 

start a shell command invisible in the background:

<?php 
$WshShell = new COM("WScript.Shell"); 
$oExec = $WshShell->Run("cmd /C dir /S %windir%", 0, false); 
?> 

start MSPaint maximized and wait for you to close it before continuing the script:

<?php 
$WshShell = new COM("WScript.Shell"); 
$oExec = $WshShell->Run("mspaint.exe", 3, true); 
?> 

For more info on the Run() method go to: http://msdn.microsoft.com/library/en-us/script56/html/wsMthRun.asp

Edited URL:

Go to https://technet.microsoft.com/en-us/library/ee156605.aspx instead as the link above no longer exists.

As was said you need to remove the FKs before. On Mysql do it like this:

ALTER TABLE `table_name` DROP FOREIGN KEY `id_name_fk`;

ALTER TABLE `table_name` DROP INDEX `id_name_fk`;

If after changing the namespace and the config/auth.php it still fails, you could try the following:

1. In the file vendor/composer/autoload_classmap.php change the line App\\User' => $baseDir . '/app/User.php',, to App\\Models\\User' => $baseDir . '/app/Models/User.php',

2. At the beginning of the file app/Services/Registrar.php change "use App\User" to "App\Models\User"

The accepted answer is correct, however sometimes you would get the "Aspnet_regiis.exe is not recognized as an internal or external command, operable program or batch file." error message.

To resolve it try the following:

1. Make sure that your .NET 4.0 installation is not corrupted (run the installer and 'Repair' it). There's also a chance it is not installed on your machine at all.

2. If you're sure you don't have .NET 4.0 installed and want to run it as .NET 2.0, try this:

If you see the message "Aspnet_regiis.exe is not recognized as an internal or external command, operable program or batch file.", switch to the C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Aspnet_regiis.exe -i at the command prompt.

In case you have a .properties file or a .ini file

Actually in case if you have any file that has key value pairs like this:

someKey=someValue
someOtherKey=someOtherValue

You can import that into webpack by a npm module called properties-reader

I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.

1. Import that from dependencies section in package.json

"properties-reader": "0.0.16"

2. Import this module into webpack.config.js on top

const PropertiesReader = require('properties-reader');

3. Read the properties file

const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;

4. Import this constant as config

externals: { 'Config': JSON.stringify(appProperties) }

5. Use it as the same way as mentioned in the accepted answer

var Config = require('Config') fetchData(Config.serverUrl + '/Enterprises/...')

To pass arguments to your python script while running a script via command line

python create_thumbnail.py test1.jpg test2.jpg

here, script name - create_thumbnail.py, argument 1 - test1.jpg, argument 2 - test2.jpg

With in the create_thumbnail.py script i use

sys.argv[1:]

which give me the list of arguments i passed in command line as ['test1.jpg', 'test2.jpg']

I'd go with boost::filesystem::extension (std::filesystem::path::extension with C++17) but if you cannot use Boost and you just have to verify the extension, a simple solution is:

bool ends_with(const std::string &filename, const std::string &ext)
{
  return ext.length() <= filename.length() &&
         std::equal(ext.rbegin(), ext.rend(), filename.rbegin());
}

if (ends_with(filename, ".conf"))
{ /* ... */ }

The key, as I understand it, is that Javascript has function level scoping vs the more common C block scoping.

Here is a good article on the subject.

Easiest ways to get file name:

val fileName = File(uri.path).name
// or
val fileName = uri.pathSegments.last()

If they don't give you the right name you should use:

fun Uri.getName(context: Context): String {
    val returnCursor = context.contentResolver.query(this, null, null, null, null)
    val nameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME)
    returnCursor.moveToFirst()
    val fileName = returnCursor.getString(nameIndex)
    returnCursor.close()
    return fileName
}

The reason behind this error is : Flask app is already running, hasn't shut down and in middle of that we try to start another instance by: with app.app_context(): #Code Before we use this with statement we need to make sure that scope of the previous running app is closed.

Just pass the list to np.array:

a = np.array(a)

You can also take this opportunity to set the dtype if the default is not what you desire.

a = np.array(a, dtype=...)

Steps

1. Create a new Activity, for your player(fullscreen) screen with menu options. Run the mediaplayer and UI in different threads.

2. For playing media - In general to play audio/video there is mediaplayer api in android. FILE_PATH is the path of file - may be url(youtube) stream or local file path

    MediaPlayer mp = new MediaPlayer();
       mp.setDataSource(FILE_PATH);
       mp.prepare();
       mp.start();
   

Also check: Android YouTube app Play Video Intent have already discussed this in detail.

Delete node folder completely from program file folder. Uninstall node.js and then reinstall it. change Path of environment variable PATH. delete .npmrc file from C:\users\yourusername

Following on Ivan Krechetov's answer, here is a function that does mail merge (actually just simple text replace) for docx and odt, without the need for an extra library.

function mailMerge($templateFile, $newFile, $row)
{
  if (!copy($templateFile, $newFile))  // make a duplicate so we dont overwrite the template
    return false; // could not duplicate template
  $zip = new ZipArchive();
  if ($zip->open($newFile, ZIPARCHIVE::CHECKCONS) !== TRUE)
    return false; // probably not a docx file
  $file = substr($templateFile, -4) == '.odt' ? 'content.xml' : 'word/document.xml';
  $data = $zip->getFromName($file);
  foreach ($row as $key => $value)
    $data = str_replace($key, $value, $data);
  $zip->deleteName($file);
  $zip->addFromString($file, $data);
  $zip->close();
  return true;
}

This will replace [Person Name] with Mina and [Person Last Name] with Mooo:

$replacements = array('[Person Name]' => 'Mina', '[Person Last Name]' => 'Mooo');
$newFile = tempnam_sfx(sys_get_temp_dir(), '.dat');
$templateName = 'personinfo.docx';
if (mailMerge($templateName, $newFile, $replacements))
{
  header('Content-type: application/msword');
  header('Content-Disposition: attachment; filename=' . $templateName);
  header('Accept-Ranges: bytes');
  header('Content-Length: '. filesize($file));
  readfile($newFile);
  unlink($newFile);
}

Beware that this function can corrupt the document if the string to replace is too general. Try to use verbose replacement strings like [Person Name].

I found this question while trying to split multiple contacts in a single vCard VCF file to separate files. Here's what I did based on Lee's code. I had to look up how to create a new StreamReader object and changed null to $null.

$reader = new-object System.IO.StreamReader("C:\Contacts.vcf")
$count = 1
$filename = "C:\Contacts\{0}.vcf" -f ($count) 

while(($line = $reader.ReadLine()) -ne $null)
{
    Add-Content -path $fileName -value $line

    if($line -eq "END:VCARD")
    {
        ++$count
        $filename = "C:\Contacts\{0}.vcf" -f ($count)
    }
}

$reader.Close()

"Hard Coding" means something that you want to embeded with your program or any project that can not be changed directly. For example if you are using a database server, then you must hardcode to connect your database with your project and that can not be changed by user. Because you have hard coded.

There is no difference.

The Java Software Development Kit (Java SDK) used to be called the Java Development Kit (JDK) before the marketing department at Sun got crazy with the "tm" and terminology. For political reasons & for sanity, they call the meaningful names (jdk) & versions (1.2 / 1.3 / 1.4 1.5 / 1.6) "engineering" terms. The marketing terms are "Java2 platform" (aka jdk 1.2 thru 1.4) or Java5 (aka jdk 1.5) or Java6 (aka jdk1.6). I'm getting a headache just thinking about it.

simplejson module is simply 1,5 times faster than json (On my computer, with simplejson 2.1.1 and Python 2.7 x86).

If you want, you can try the benchmark: http://abral.altervista.org/jsonpickle-bench.zip On my PC simplejson is faster than cPickle. I would like to know also your benchmarks!

Probably, as said Coady, the difference between simplejson and json is that simplejson includes _speedups.c. So, why don't python developers use simplejson?

This is an interesting question and since it isn't explained very explicitly in the documentation I'll answer this by going through the sourcecode of mod_rewrite; demonstrating a big benefit of open-source.

In the top section you'll quickly spot the defines used to name these flags:

#define CONDFLAG_NONE               1<<0
#define CONDFLAG_NOCASE             1<<1
#define CONDFLAG_NOTMATCH           1<<2
#define CONDFLAG_ORNEXT             1<<3
#define CONDFLAG_NOVARY             1<<4

and searching for CONDFLAG_ORNEXT confirms that it is used based on the existence of the [OR] flag:

else if (   strcasecmp(key, "ornext") == 0
         || strcasecmp(key, "OR") == 0    ) {
    cfg->flags |= CONDFLAG_ORNEXT;
}

The next occurrence of the flag is the actual implementation where you'll find the loop that goes through all the RewriteConditions a RewriteRule has, and what it basically does is (stripped, comments added for clarity):

# loop through all Conditions that precede this Rule
for (i = 0; i < rewriteconds->nelts; ++i) {
    rewritecond_entry *c = &conds[i];

    # execute the current Condition, see if it matches
    rc = apply_rewrite_cond(c, ctx);

    # does this Condition have an 'OR' flag?
    if (c->flags & CONDFLAG_ORNEXT) {
        if (!rc) {
            /* One condition is false, but another can be still true. */
            continue;
        }
        else {
            /* skip the rest of the chained OR conditions */
            while (   i < rewriteconds->nelts
                   && c->flags & CONDFLAG_ORNEXT) {
                c = &conds[++i];
            }
        }
    }
    else if (!rc) {
        return 0;
    }
}

You should be able to interpret this; it means that OR has a higher precedence, and your example indeed leads to if ( (A OR B) AND (C OR D) ). If you would, for example, have these Conditions:

RewriteCond A [or]
RewriteCond B [or]
RewriteCond C
RewriteCond D

it would be interpreted as if ( (A OR B OR C) and D ).

Incorrect:

SELECT * FROM customers WHERE name LIKE '%Bob Smith%';

Instead:

select count(*)
from rearp.customers c
where c.name  LIKE '%Bob smith.8%';

select count will just query (totals)

C will link the db.table to the names row you need this to index

LIKE should be obvs

8 will call all references in DB 8 or less (not really needed but i like neatness)

there is another 'benefit'

if the member variable type does not support null initialization or if its a reference (which cannot be null initialized) then you have no choice but to supply an initialization list

//poly [x,y, x,y, x,y.....];
var poly=[ 5,5, 100,50, 50,100, 10,90 ];
var canvas=document.getElementById("canvas")
var ctx = canvas.getContext('2d');
ctx.fillStyle = '#f00';

ctx.beginPath();
ctx.moveTo(poly[0], poly[1]);
for( item=2 ; item < poly.length-1 ; item+=2 ){ctx.lineTo( poly[item] , poly[item+1] )}

ctx.closePath();
ctx.fill();

You can use jquery for this:

$('body').bind('copy paste',function(e) {
    e.preventDefault(); return false; 
});

Using jQuery bind() and specififying your desired eventTypes .

The only difference between object literals and constructed objects are the properties inherited from the prototype.

var o = {
  'a': 3, 'b': 4,
  'doStuff': function() {
    alert(this.a + this.b);
  }
};
o.doStuff(); // displays: 7

You could make a struct factory.

function makeStruct(names) {
  var names = names.split(' ');
  var count = names.length;
  function constructor() {
    for (var i = 0; i < count; i++) {
      this[names[i]] = arguments[i];
    }
  }
  return constructor;
}

var Item = makeStruct("id speaker country");
var row = new Item(1, 'john', 'au');
alert(row.speaker); // displays: john

I know it's been a while since this thread was open. From the answer given by chmike and improved by Aqib Mumtaz. They give a good answer but only works for a infinite line as said Aqib. So I add some comparisons to know if the line segment touch the circle, I write it in Python.

def LineIntersectCircle(c, r, p1, p2):
    #p1 is the first line point
    #p2 is the second line point
    #c is the circle's center
    #r is the circle's radius

    p3 = [p1[0]-c[0], p1[1]-c[1]]
    p4 = [p2[0]-c[0], p2[1]-c[1]]

    m = (p4[1] - p3[1]) / (p4[0] - p3[0])
    b = p3[1] - m * p3[0]

    underRadical = math.pow(r,2)*math.pow(m,2) + math.pow(r,2) - math.pow(b,2)

    if (underRadical < 0):
        print("NOT")

Just stick in a file and call it "ServiceModelSamples.bat" or something.

You could add "@echo off" as line one, so the command doesn't get printed to the screen:

@echo off
svcutil.exe /language:cs /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceModelSamples/service

Besides the usages that JAiro mentioned, I like this one:

def getConnectionProps = {
    ( Config.getHost, Config.getPort, Config.getSommElse, Config.getSommElsePartTwo )
}

If someone needs all connection properties, he can do:

val ( host, port, sommEsle, someElsePartTwo ) = getConnectionProps

If you need just a host and a port, you can do:

val ( host, port, _, _ ) = getConnectionProps

Use the following code:

$(document).ready(function() {
    $('.date-pick').datepicker( {
     onSelect: function(date) {
        alert(date)
     },
    selectWeek: true,
    inline: true,
    startDate: '01/01/2000',
    firstDay: 1,
  });
});

You can adjust the parameters yourself :-)

The accepted answer does not "make Git "forget" about a file..." (historically). It only makes git ignore the file in the present/future.

This method makes git completely forget ignored files (past/present/future), but does not delete anything from working directory (even when re-pulled from remote).

This method requires usage of /.git/info/exclude (preferred) OR a pre-existing .gitignore in all the commits that have files to be ignored/forgotten. ¹

All methods of enforcing git ignore behavior after-the-fact effectively re-write history and thus have significant ramifications for any public/shared/collaborative repos that might be pulled after this process. ²

General advice: start with a clean repo - everything committed, nothing pending in working directory or index, and make a backup!

Also, the comments/revision history of this answer (and revision history of this question) may be useful/enlightening.

#commit up-to-date .gitignore (if not already existing)
#this command must be run on each branch

git add .gitignore
git commit -m "Create .gitignore"

#apply standard git ignore behavior only to current index, not working directory (--cached)
#if this command returns nothing, ensure /.git/info/exclude AND/OR .gitignore exist
#this command must be run on each branch

git ls-files -z --ignored --exclude-standard | xargs -0 git rm --cached

#Commit to prevent working directory data loss!
#this commit will be automatically deleted by the --prune-empty flag in the following command
#this command must be run on each branch

git commit -m "ignored index"

#Apply standard git ignore behavior RETROACTIVELY to all commits from all branches (--all)
#This step WILL delete ignored files from working directory UNLESS they have been dereferenced from the index by the commit above
#This step will also delete any "empty" commits.  If deliberate "empty" commits should be kept, remove --prune-empty and instead run git reset HEAD^ immediately after this command

git filter-branch --tree-filter 'git ls-files -z --ignored --exclude-standard | xargs -0 git rm -f --ignore-unmatch' --prune-empty --tag-name-filter cat -- --all

#List all still-existing files that are now ignored properly
#if this command returns nothing, it's time to restore from backup and start over
#this command must be run on each branch

git ls-files --other --ignored --exclude-standard

Finally, follow the rest of this GitHub guide (starting at step 6) which includes important warnings/information about the commands below.

git push origin --force --all
git push origin --force --tags
git for-each-ref --format="delete %(refname)" refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --prune=now

Other devs that pull from now-modified remote repo should make a backup and then:

#fetch modified remote

git fetch --all

#"Pull" changes WITHOUT deleting newly-ignored files from working directory
#This will overwrite local tracked files with remote - ensure any local modifications are backed-up/stashed

git reset FETCH_HEAD

Footnotes

¹ Because /.git/info/exclude can be applied to all historical commits using the instructions above, perhaps details about getting a .gitignore file into the historical commit(s) that need it is beyond the scope of this answer. I wanted a proper .gitignore to be in the root commit, as if it was the first thing I did. Others may not care since /.git/info/exclude can accomplish the same thing regardless where the .gitignore exists in the commit history, and clearly re-writing history is a very touchy subject, even when aware of the ramifications.

FWIW, potential methods may include git rebase or a git filter-branch that copies an external .gitignore into each commit, like the answers to this question

² Enforcing git ignore behavior after-the-fact by committing the results of a standalone git rm --cached command may result in newly-ignored file deletion in future pulls from the force-pushed remote. The --prune-empty flag in the following git filter-branch command avoids this problem by automatically removing the previous "delete all ignored files" index-only commit. Re-writing git history also changes commit hashes, which will wreak havoc on future pulls from public/shared/collaborative repos. Please understand the ramifications fully before doing this to such a repo. This GitHub guide specifies the following:

Tell your collaborators to rebase, not merge, any branches they created off of your old (tainted) repository history. One merge commit could reintroduce some or all of the tainted history that you just went to the trouble of purging.

Alternative solutions that do not affect the remote repo are git update-index --assume-unchanged </path/file> or git update-index --skip-worktree <file>, examples of which can be found here.

This is how I did it.

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

You can use

if (person == null || String.valueOf(person.getId() == null)) 

in addition to regular approach

person.getId() == 0

You can turn off foreign key checks:

SET FOREIGN_KEY_CHECKS = 0;

/* DO WHAT YOU NEED HERE */

SET FOREIGN_KEY_CHECKS = 1;

Please make sure to NOT use this on production and have a backup.

What is a file with extension .sh?

It is a Bourne shell script. They are used in many variations of UNIX-like operating systems. They have no "language" and are interpreted by your shell (interpreter of terminal commands) or if the first line is in the form

#!/path/to/interpreter

they will use that particular interpreter. Your file has the first line:

#!/bin/bash

and that means that it uses Bourne Again Shell, so called bash. It is for all practical purposes a replacement for good old sh.

Depending upon the interpreter you will have different language in which the file is written.

Keep in mind, that in UNIX world, it is not the extension of the file that determines what the file is (see How to execute a shell script).

If you come from the world of DOS/Windows, you will be familiar with files that have .bat or .cmd extensions (batch files). They are not similar in content, but are akin in design.

How to execute a shell script

Unlike some silly operating systems, *nix does not rely exclusively on extensions to determine what to do with a file. Permissions are also used. This means that if you attempt to run the shell script after downloading it, it will be the same as trying to "run" any text file. The ".sh" extension is there only for your convenience to recognize that file.

You will need to make the file executable. Let's assume that you have downloaded your file as file.sh, you can then run in your terminal:

chmod +x file.sh

chmod is a command for changing file's permissions, +x sets execute permissions (in this case for everybody) and finally you have your file name.

You can also do it in GUI. Most of the time you can right click on the file and select properties, in XUbuntu the permissions options look like this:

If you do not wish to change the permissions. You can also force the shell to run the command. In the terminal you can run:

bash file.sh

The shell should be the same as in the first line of your script.

How safe is it?

You may find it weird that you must perform another task manually in order to execute a file. But this is partially because of strong need for security.

Basically when you download and run a bash script, it is the same thing as somebody telling you "run all these commands in sequence on your computer, I promise that the results will be good and safe". Ask yourself if you trust the party that has supplied this file, ask yourself if you are sure that have downloaded the file from the same place as you thought, maybe even have a glance inside to see if something looks out of place (although that requires that you know something about *nix commands and bash programming).

Unfortunately apart from the warning above I cannot give a step-by-step description of what you should do to prevent evil things from happening with your computer; so just keep in mind that any time you get and run an executable file from someone you're actually saying, "Sure, you can use my computer to do something".

That's a bad practice to use the == equality operator instead of ===.

undefined === undefined // true
null == undefined // true
null === undefined // false

The object.x === undefined should return true if x is unknown property.

In chapter Bad Parts of JavaScript: The Good Parts, Crockford writes the following:

If you attempt to extract a value from an object, and if the object does not have a member with that name, it returns the undefined value instead.

In addition to undefined, JavaScript has a similar value called null. They are so similar that == thinks they are equal. That confuses some programmers into thinking that they are interchangeable, leading to code like

value = myObject[name];
if (value == null) {
    alert(name + ' not found.');
}

It is comparing the wrong value with the wrong operator. This code works because it contains two errors that cancel each other out. That is a crazy way to program. It is better written like this:

value = myObject[name];
if (value === undefined) {
    alert(name + ' not found.');
}

Edit: As pointed out in comments (Mario Awad & Brock Hensley), use .find to get the children

$("form").each(function(){
    $(this).find(':input') //<-- Should return all input elements in that specific form.
});

forms also have an elements collection, sometimes this differs from children such as when the form tag is in a table and is not closed.

var summary = [];_x000D_
$('form').each(function () {_x000D_
    summary.push('Form ' + this.id + ' has ' + $(this).find(':input').length + ' child(ren).');_x000D_
    summary.push('Form ' + this.id + ' has ' + this.elements.length + ' form element(s).');_x000D_
});_x000D_
_x000D_
$('#results').html(summary.join('<br />'));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<form id="A" style="display: none;">_x000D_
    <input type="text" />_x000D_
    <button>Submit</button>_x000D_
</form>_x000D_
<form id="B" style="display: none;">_x000D_
    <select><option>A</option></select>_x000D_
    <button>Submit</button>_x000D_
</form>_x000D_
_x000D_
<table bgcolor="white" cellpadding="12" border="1" style="display: none;">_x000D_

<tr><td><h1><i><b>UserID:</b></i></h1></td><td><form id="login" name="login" method="post"><input_x000D_

May be :input selector is what you want

$("form").each(function(){ $(':input', this)//<-- Should return all input elements in that specific form. });

$("form").each(function(){
    $(this).filter(':input') //<-- Should return all input elements in that specific form.
});

To know where your .sqlite file is stored in your AppDelegate.m add the following code

- (NSURL *)applicationDocumentsDirectory
{
    NSLog(@"%@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory      inDomains:NSUserDomainMask] lastObject]);

    return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory     inDomains:NSUserDomainMask] lastObject];
 }

now call this method in AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

  //call here
   [self applicationDocumentsDirectory];

}

You are trying to run bash, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d, but you can do this by adding -it to the command line, which ensures that the container has a valid tty associated with it and that stdin remains connected:

docker run -it -d -p 52022:22 basickarl/docker-git-test

You would more commonly run some sort of long-lived non-interactive process (like sshd, or a web server, or a database server, or a process manager like systemd or supervisor) when starting detached containers.

If you are trying to run a service like sshd, you cannot simply run service ssh start. This will -- depending on the distribution you're running inside your container -- do one of two things:

• It will try to contact a process manager like systemd or upstart to start the service. Because there is no service manager running, this will fail.

• It will actually start sshd, but it will be started in the background. This means that (a) the service sshd start command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.

If you want to run just ssh in a container, consider an example like this.

If you want to run sshd and other processes inside the container, you will need to investigate some sort of process supervisor.

The best way to skip the first item(s) is:

from itertools import islice
for car in islice(cars, 1, None):
    # do something

islice in this case is invoked with a start-point of 1, and an end point of None, signifying the end of the iterator.

To be able to skip items from the end of an iterable, you need to know its length (always possible for a list, but not necessarily for everything you can iterate on). for example, islice(cars, 1, len(cars)-1) will skip the first and last items in the cars list.

Type this in Windows PowerShell or CMD:

"[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")"

After running the command, please restart PowerShell or CMD. If it still doesn't work, restart your PC.

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

I know this was posted about a year ago, but this is for users for future reference.

I came across similar issue. In my case (i will try to be brief, please do let me know if you would like more detail), i was trying to check if a string was empty or not (string is the subject of an email). It always returned the same error message no matter what i did. I knew i was doing it right but it still kept throwing the same error message. Then it dawned in me that, i was checking if the subject (string) of an email (instance/object), what if the email(instance) was already a null at the first place. How could i check for a subject of an email, if the email is already a null..i checked if the the email was empty, it worked fine.

while checking for the subject(string) i used IsNullorWhiteSpace(), IsNullOrEmpty() methods.

if (email == null)
{     
     break;    
}
else
{    
     // your code here    
}

Two problems- List is empty. You need to add some buttons to the list first. Second problem: You can't add buttons to "this". "This" is not referencing what you think, I think. Change this to reference a Panel for instance.

//Assume you have on your .aspx page:
<asp:Panel ID="Panel_Controls" runat="server"></asp:Panel>


private void button1_Click(object sender, EventArgs e)
    {
        List<Button> buttons = new List<Button>();


        for (int i = 0; i < buttons.Capacity; i++)
        {
            Panel_Controls.Controls.Add(buttons[i]);   
        }
    }

You can't do this automatically. Your JS can't see the files in the same directory as it.

Easiest is probably to give a list of those image names to your JavaScript.

Otherwise, you might be able to fetch a directory listing from the web server using JS and parse it to get the list of images.

The answer is weaved amongst the various posts here, I'll so my best, but it looks like a really simple and obvious reason.

1) is that there usually is a "user" variable in the udev rule some thing like USER="your_user" probably right after the GROUP="plugdev"

2) You need to use the correct SYSFS{idVendor}==”####" and SYSFS{idProduct}=="####" values for your device/s. If you have devices from more than one manufacture, say like one from Samsung and one from HTC, then you need to have an entry(rule) for each vendor, not an entry for each device but for each different vendor you will use, so you need an entry for HTC and Samsung. It looks like you have your entry for Samsung now you need another. Remember the USER="your_user". Use 'lsusb' like Robert Seimer suggests to find the idVendor and idProduct, they are usually some numbers and letters in this format X#X#:#X#X I think the first one is the idVendor and the second idProduct but your going to need to do this for each brand of phone/tablet you have.

3) I havent figured out how 51-adb.rules and 99-adb.rules are different or why.

4) maybe try adding "plugdev" group to your user with "usermod -a -G plugdev your_user", Try that at your own risk, though I don't thinks it anyriskier than launching a gui as root but I believe if necessary you should at least use "gksudo eclipse" instead.

I hope that helped clearify some things, the udev rules syntax is a bit of a mystery to me aswell, but from what I hear it can be different for different systems so try some things out, one ate a time, and note what change works.

Below code handles upper and lower cases as well and leaves other character as it is.

import java.util.Scanner;

public class CaesarCipher
{
    public static void main(String[] args)
    {
    Scanner in = new Scanner(System.in);
    int length = Integer.parseInt(in.nextLine());
    String str = in.nextLine();
    int k = Integer.parseInt(in.nextLine());

    k = k % 26;

    System.out.println(encrypt(str, length, k));

    in.close();
    }

    private static String encrypt(String str, int length, int shift)
    {
    StringBuilder strBuilder = new StringBuilder();
    char c;
    for (int i = 0; i < length; i++)
    {
        c = str.charAt(i);
        // if c is letter ONLY then shift them, else directly add it
        if (Character.isLetter(c))
        {
        c = (char) (str.charAt(i) + shift);
        // System.out.println(c);

        // checking case or range check is important, just if (c > 'z'
        // || c > 'Z')
        // will not work
        if ((Character.isLowerCase(str.charAt(i)) && c > 'z')
            || (Character.isUpperCase(str.charAt(i)) && c > 'Z'))

            c = (char) (str.charAt(i) - (26 - shift));
        }
        strBuilder.append(c);
    }
    return strBuilder.toString();
    }
}

First, check that whatever you are returning via unicode is a String.

If it is not a string you can change it to a string like this (where self.id is an integer)

def __unicode__(self):
    return '%s' % self.id

following which, if it still doesn't work, restart your ./manage.py shell for the changes to take effect and try again. It should work.

if you want to operate with list of numbers it is better to use NumPy arrays:

import numpy
a = [1, 1, 1 ,1, 1]
ar = numpy.array(a)
print ar + 2

gives

[3, 3, 3, 3, 3]

Reference ServiceBase to your class and put the below code in the OnStartevent:

Constants.TimeIntervalValue = 1 (hour)..Ideally you should set this value in config file.

StartSendingMails = function name you want to run in the application.

 protected override void OnStart(string[] args)
        {
            // It tells in what interval the service will run each time.
            Int32 timeInterval = Int32.Parse(Constants.TimeIntervalValue) * 60 * 60 * 1000;
            base.OnStart(args);
            TimerCallback timerDelegate = new TimerCallback(StartSendingMails);
            serviceTimer = new Timer(timerDelegate, null, 0, Convert.ToInt32(timeInterval));
        }

Normally you cant update a page from a servlet. Client (browser) has to request an update. Eiter client loads a whole new page or it requests an update to a part of an existing page. This technique is called Ajax.

It depends what is the character and what encoding it is in:

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

• An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

• A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

• A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

• A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

• An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

• The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

That would mean that there are between 0.03125 and 0.125 characters in a bit.

You can't just use a percentage width for the div? Setting the width to 50% will make it 50% as wide as the window (assuming there is no parent element with a width assigned to it).

Print the PDF header (using header() function) like: header("Content-type: application/pdf");

and then just echo the content of the PDF file you created (instead of writing it to disk).

Try this -

plt.xticks(rotation=90)

myokyawhtun's solution worked best for me (using PHP 5.4)

You will still get an error though - I resolved using the following:

Line 269 of fpdf_tpl.php - changed the function parameters to:

function Image($file, $x=null, $y=null, $w=0, $h=0, $type='', $link='',$align='', $resize=false, $dpi=300, $palign='', $ismask=false, $imgmask=false, $border=0) { 

I also made this same change on line 898 of fpdf.php

this does not affect resulting code - it is compilation time operator and the code generated with or without it will be the same. When you have to use it, depends on context. For example you have to use it, as you said, when you have local variable that shadows class variable and you want refer to class variable and not local one.

edit: by "resulting code will be the same" I mean of course, when some variable in local scope doesn't hide the one belonging to class. Thus

class POJO {
   protected int i;

   public void modify() {
      i = 9;
   }

   public void thisModify() {
      this.i = 9;
   }
}

resulting code of both methods will be the same. The difference will be if some method declares local variable with the same name

  public void m() {
      int i;
      i = 9;  // i refers to variable in method's scope
      this.i = 9; // i refers to class variable
  }

You can also use JQuery methods to accomplish this:

<script type="text/javascript">
if ($('#remember')[0].checked) 
{
 alert("checked");
}
</script>

Invoke-Expression should work perfectly, just make sure you are using it correctly. For your case it should look like this:

Invoke-Expression "$scriptPath $argumentList"

I tested this approach with Get-Service and seems to be working as expected.

To complement Jakub's answer, if you have access to the remote git server in ssh, you can go into the git remote directory and set:

user@remote$ git config receive.denyNonFastforwards false

Then go back to your local repo, try again to do your commit with --force:

user@local$ git push origin +master:master --force

And finally revert the server's setting in the original protected state:

user@remote$ git config receive.denyNonFastforwards true

Try this. I purposely broke out various parts so you can move things around.

Long story short, unless len(l1 + l2) ~ 1000000 use:

L = l1 + l2
L.sort()

Description of the figure and source code can be found here.

Your arguments are in the wrong order. The connection comes first according to the docs

<?php
require("constants.php");

// 1. Create a database connection
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);

if (!$connection) {
    error_log("Failed to connect to MySQL: " . mysqli_error($connection));
    die('Internal server error');
}

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    error_log("Database selection failed: " . mysqli_error($connection));
    die('Internal server error');
}

?>

Using the arrow function, and sorting by the second string field

var a = [[12, 'CCC'], [58, 'AAA'], [57, 'DDD'], [28, 'CCC'],[18, 'BBB']];_x000D_
a.sort((a, b) => a[1].localeCompare(b[1]));_x000D_
console.log(a)

unsigned char is the heart of all bit trickery. In almost ALL compiler for ALL platform an unsigned char is simply a byte and an unsigned integer of (usually) 8 bits that can be treated as a small integer or a pack of bits.

In addiction, as someone else has said, the standard doesn't define the sign of a char. so you have 3 distinct char types: char, signed char, unsigned char.

Run java with CLASSPATH environmental variable pointing to driver's JAR file, e.g.

CLASSPATH='.:drivers/mssql-jdbc-6.2.1.jre8.jar' java ConnectURL

Where drivers/mssql-jdbc-6.2.1.jre8.jar is the path to driver file (e.g. JDBC for for SQL Server).

The ConnectURL is the sample app from that driver (samples/connections/ConnectURL.java), compiled via javac ConnectURL.java.

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

There is no property to make the checkbox readonly. But you can try this trick.

<input type="checkbox" onclick="return false" />

DEMO

Some more spins on the <a name=""> trick:

<a id="a-link"></a> Title
------

#### <a id="a-link"></a> Title (when you wanna control the h{N} with #'s)

The answer's here, I think.

It's better if you do git rm <fileName>, though.

Using HAL (kernel 2.6.17 and up):

#! /bin/bash
hal-find-by-property --key volume.fsusage --string filesystem |
while read udi ; do
    # ignore optical discs
    if [[ "$(hal-get-property --udi $udi --key volume.is_disc)" == "false" ]]; then
        dev=$(hal-get-property --udi $udi --key block.device)   
        fs=$(hal-get-property --udi $udi --key volume.fstype) 
        echo $dev": "$fs
    fi 
done

This method doesn't use any if:

data[:75] + bool(data[75:]) * '..'

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

From How do I install a Python package with a .whl file? [sic], How do I install a Python package USING a .whl file ?

For all Windows platforms:

1) Download the .WHL package install file.

2) Make Sure path [C:\Progra~1\Python27\Scripts] is in the system PATH string. This is for using both [pip.exe] and [easy-install.exe].

3) Make sure the latest version of pip.EXE is now installed. At this time of posting:

pip.EXE --version

  pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

4) Run pip.EXE in an Admin command shell.

 - Open an Admin privileged command shell.

 > easy_install.EXE --upgrade  pip

 - Check the pip.EXE version:
 > pip.EXE --version

 pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

 > pip.EXE install --use-wheel --no-index 
     --find-links="X:\path to wheel file\DownloadedWheelFile.whl"

Be sure to double-quote paths or path\filenames with embedded spaces in them ! Alternatively, use the MSW 'short' paths and filenames.

I have just discovered a way to append text and its working fine at least.

 var text = 'Put any text here';
 $('#text').append(text);

You can change text according to your need.

Hope this helps.

Using the width function:

$('div#somediv').width('70%');

will turn:

<div id="somediv" />

into:

<div id="somediv" style="width: 70%;"/>

The mysql_* functions are deprecated and unsafe. The code in your question in vulnerable to injection attacks. It is highly recommended that you use the PDO extension instead, like so:

session_start();

$query = "SELECT 'id' FROM Users WHERE username = :name LIMIT 1";
$statement = $PDO->prepare($query);
$params = array(
    'name' => $_GET["username"]
);
$statement->execute($params);
$user_data = $statement->fetch();

$_SESSION['myid'] = $user_data['id'];

Where $PDO is your PDO object variable. See https://www.php.net/pdo_mysql for more information about PHP and PDO.

For extra help:

Here's a jumpstart on how to connect to your database using PDO:

$database_username = "YOUR_USERNAME";
$database_password = "YOUR_PASSWORD";
$database_info = "mysql:host=localhost;dbname=YOUR_DATABASE_NAME";
try
{
    $PDO = new PDO($database_info, $database_username, $database_password);
}
catch(PDOException $e)
{
    // Handle error here
}

I just experienced this problem.

The problem was caused by my controller method attempting return type of String (view name) when it exits. When the method would exit, a second response stream would be initiated.

Changing the controller method return type to void resolved the problem.

I hope this helps if anyone else experiences this problem.

Create a div that is the line with the code like this:

CSS

div#lineHorizontal {
    background-color: #000;
    width: //the width of the line or how far it goes sidewards;
    height: 2px;
    display: inline-block;
    margin: 0px;
 }
div#block {
    background-color: #777;
    display: inline-block;
    margin: 0px;
}

HTML

<div id="block">
</div>
<div id="lineHorizontal">
</div>
<div id="block">
</div>

This will display a block with a horizontal line to another block.

On mobile devices you could use (caniuse.com/transforms2d)

LinkButton component - a solution for React Router v4

First, a note about many other answers to this question.

?? Nesting <button> and <a> is not valid html. ??

Any answer here which suggests nesting a html button in a React Router Link component (or vice-versa) will render in a web browser, but it is not semantic, accessible, or valid html:

<a stuff-here><button>label text</button></a>
<button><a stuff-here>label text</a></button>

?Click to validate this markup with validator.w3.org ?

This can lead to layout/styling issues as buttons are not typically placed inside links.

Using an html <button> tag with React Router <Link> component.

If you only want an html button tag…

<button>label text</button>

…then, here's the right way to get a button that works like React Router’s Link component…

Use React Router’s withRouter HOC to pass these props to your component:

• history
• location
• match
• staticContext

LinkButton component

Here’s a LinkButton component for you to copy/pasta:

// file: /components/LinkButton.jsx
import React from 'react'
import PropTypes from 'prop-types'
import { withRouter } from 'react-router'

const LinkButton = (props) => {
  const {
    history,
    location,
    match,
    staticContext,
    to,
    onClick,
    // ? filtering out props that `button` doesn’t know what to do with.
    ...rest
  } = props
  return (
    <button
      {...rest} // `children` is just another prop!
      onClick={(event) => {
        onClick && onClick(event)
        history.push(to)
      }}
    />
  )
}

LinkButton.propTypes = {
  to: PropTypes.string.isRequired,
  children: PropTypes.node.isRequired
}

export default withRouter(LinkButton)

Then import the component:

import LinkButton from '/components/LinkButton'

Use the component:

<LinkButton to='/path/to/page'>Push My Buttons!</LinkButton>

If you need an onClick method:

<LinkButton
  to='/path/to/page'
  onClick={(event) => {
    console.log('custom event here!', event)
  }}
>Push My Buttons!</LinkButton>

Update: If you're looking for another fun option made available after the above was written, check out this useRouter hook.

You can set the value property using client script after the element is created:

<input type="text" id="fee" />

<script type="text/javascript>
document.getElementById('fee').value = '1000';
</script>

It happens when you don't properly close the code block:

if (condition){
  // your code goes here*
  { // This doesn't close the code block

Correct way:

if (condition){
  // your code goes here
} // Close the code block

Try this...

const str = "linto.yahoo.com."
console.log(str.charAt(str.length-1));

Login into the machine as oracle login user id( where oracle is installed)..

1. Add ORACLE_HOME = <Oracle installation Directory> in Environment variable

2. Open a command prompt

3. Change the directory to %ORACLE_HOME%\bin

4. type the command sqlplus /nolog

5. SQL> connect /as sysdba

6. SQL> alter user SYS identified by "newpassword";

One more check, while oracle installation and database confiuration assistant setup, if you configure any database then you might have given password and checked the same password for all other accounts.. If so, then you try with the password which you have given in your database configuration assistant setup.

Hope this will work for you..

In SQL, I would have do it in one shot as

update table1 set col1 = new_value where col1 = old_value

but in Python Pandas, we could just do this:

data = [['ram', 10], ['sam', 15], ['tam', 15]] 
kids = pd.DataFrame(data, columns = ['Name', 'Age']) 
kids

which will generate the following output :

    Name    Age
0   ram     10
1   sam     15
2   tam     15

now we can run:

kids.loc[kids.Age == 15,'Age'] = 17
kids

which will show the following output

Name    Age
0   ram     10
1   sam     17
2   tam     17

which should be equivalent to the following SQL

update kids set age = 17 where age = 15

The original answer is actually correct, but lacks explanation. I would like to add some explanations and modifications.

I suggest reading this short introduction https://httpd.apache.org/docs/2.4/rewrite/intro.html (15mins) and reference these 2 pages while reading.

https://httpd.apache.org/docs/2.4/mod/mod_rewrite.html https://httpd.apache.org/docs/2.4/rewrite/flags.html

This is the basic rule to hide index.php from the URL. Put this in your root .htaccess file.

mod_rewrite must be enabled with PHP and this will work for the PHP version higher than 5.2.6.

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) /index.php/$1 [L]

Think %{REQUEST_FILENAME} as the the path after host.

E.g. https://www.example.com/index.html, %{REQUEST_FILENAME} is /index.html

So the last 3 lines means, if it's not a regular file !-f and not a directory !-d, then do the RewriteRule.

As for RewriteRule formats:

So RewriteRule (.*) /index.php/$1 [L] means, if the 2 RewriteCond are satisfied, it (.*) would match everything after the hostname. . matches any single character , .* matches any characters and (.*) makes this a variables can be references with $1, then replace with /index.php/$1. The final effect is to add a preceding index.php to the whole URL path.

E.g. for https://www.example.com/hello, it would produce, https://www.example.com/index.php/hello internally.

Another key problem is that this indeed solve the question. Internally, (I guess) it always need https://www.example.com/index.php/hello, but with rewriting, you could visit the site without index.php, apache adds that for you internally.

Btw, making an extra .htaccess file is not very recommended by the Apache doc.

Rewriting is typically configured in the main server configuration setting (outside any <Directory> section) or inside <VirtualHost> containers. This is the easiest way to do rewriting and is recommended

The thread is very old, but I came looking for answer here hence providing new solution.

With MongoDB version 3.6+, it is now possible to use the positional operator to update all items in an array. See official documentation here.

Following query would work for the question asked here. I have also verified with Java-MongoDB driver and it works successfully.

.update(   // or updateMany directly, removing the flag for 'multi'
   {"events.profile":10},
   {$set:{"events.$[].handled":0}},  // notice the empty brackets after '$' opearor
   false,
   true
)

Hope this helps someone like me.

var now = System.DateTime.Now;

var result = now.AddDays(-((now.DayOfWeek - System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat.FirstDayOfWeek + 7) % 7)).Date;

In 1.0 and 2.0 you can use createElement prop of Router to specify how exactly to create your target element. Documentation source

function createWithDefaultProps(Component, props) {
    return <Component {...props} myprop="value" />;
}

// and then    
<Router createElement={createWithDefaultProps}>
    ...
</Router>

GhostDoc!

Right-click on the function, select "Document this" and

private bool FindTheFoo(int numberOfFoos)

becomes

/// <summary>
/// Finds the foo.
/// </summary>
/// <param name="numberOfFoos">The number of foos.</param>
/// <returns></returns>
private bool FindTheFoo(int numberOfFoos)

(yes, it is all autogenerated).

It has support for C#, VB.NET and C/C++. It is per default mapped to Ctrl+Shift+D.

Remember: you should add information beyond the method signature to the documentation. Don't just stop with the autogenerated documentation. The value of a tool like this is that it automatically generates the documentation that can be extracted from the method signature, so any information you add should be new information.

That being said, I personally prefer when methods are totally selfdocumenting, but sometimes you will have coding-standards that mandate outside documentation, and then a tool like this will save you a lot of braindead typing.

If you want to delete any commit then you might need to use git rebase command

git rebase -i HEAD~2

it will show you last 2 commit messages, if you delete the commit message and save that file deleted commit will automatically disappear...

NO, when you are using only one "=" you are assigning the variable.

You must use "==" : You must use "===" :

if (somevar === '836e3ef9-53d4-414b-a401-6eef16ac01d6'){
 $("#code").text(data.DATA[0].ID);
}

You could use fonction like .toLowerCase() to avoid case problem if you want

To be able to automatically throw an error when x become less than zero throughout the function. You can use class descriptors. Here is an example:

class LessThanZeroException(Exception):
    pass

class variable(object):
    def __init__(self, value=0):
        self.__x = value

    def __set__(self, obj, value):
        if value < 0:
            raise LessThanZeroException('x is less than zero')

        self.__x  = value

    def __get__(self, obj, objType):
        return self.__x

class MyClass(object):
    x = variable()

>>> m = MyClass()
>>> m.x = 10
>>> m.x -= 20
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "my.py", line 7, in __set__
    raise LessThanZeroException('x is less than zero')
LessThanZeroException: x is less than zero

Set it in the body selector of your css. E.g.

body {
    font: 16px Arial, sans-serif;
}

However having a simple git pull as a deployment process is usually a bad idea and should be avoided in favor of a real deployment script.

It turns out you can do this, with the help of the built-in Zip File System provider. However, passing a resource URI directly to Paths.get won't work; instead, one must first create a zip filesystem for the jar URI without the entry name, then refer to the entry in that filesystem:

static Path resourceToPath(URL resource)
throws IOException,
       URISyntaxException {

    Objects.requireNonNull(resource, "Resource URL cannot be null");
    URI uri = resource.toURI();

    String scheme = uri.getScheme();
    if (scheme.equals("file")) {
        return Paths.get(uri);
    }

    if (!scheme.equals("jar")) {
        throw new IllegalArgumentException("Cannot convert to Path: " + uri);
    }

    String s = uri.toString();
    int separator = s.indexOf("!/");
    String entryName = s.substring(separator + 2);
    URI fileURI = URI.create(s.substring(0, separator));

    FileSystem fs = FileSystems.newFileSystem(fileURI,
        Collections.<String, Object>emptyMap());
    return fs.getPath(entryName);
}

Update:

It’s been rightly pointed out that the above code contains a resource leak, since the code opens a new FileSystem object but never closes it. The best approach is to pass a Consumer-like worker object, much like how Holger’s answer does it. Open the ZipFS FileSystem just long enough for the worker to do whatever it needs to do with the Path (as long as the worker doesn’t try to store the Path object for later use), then close the FileSystem.

It sounds like your m2eclipse install is using the embedded Maven, which has its own repository (located under user home) and settings.

If you open up the Maven preferences (Window->Preferences->Maven->Installations, you can add your Maven installation by selecting Add... then browsing to the M2_HOME directory.

Wrong. That doesn't work for me.

For me this one works:

curl 
-H 'SOAPACTION: "urn:samsung.com:service:MainTVAgent2:1#CheckPIN"'   
-X POST 
-H 'Content-type: text/xml'   
-d @/tmp/pinrequest.xml 
192.168.1.5:52235/MainTVServer2/control/MainTVAgent2

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

  public class TestDate {

    public static void main(String[] args) {
    // TODO Auto-generated method stub

    String fromDate = "18-FEB-2018";
    String toDate = "20-FEB-2018";

    String requestDate = "19/02/2018";  
    System.out.println(checkBetween(requestDate,fromDate, toDate));
}

public static boolean checkBetween(String dateToCheck, String startDate, String endDate) {
    boolean res = false;
    SimpleDateFormat fmt1 = new SimpleDateFormat("dd-MMM-yyyy"); //22-05-2013
    SimpleDateFormat fmt2 = new SimpleDateFormat("dd/MM/yyyy"); //22-05-2013
    try {
     Date requestDate = fmt2.parse(dateToCheck);
     Date fromDate = fmt1.parse(startDate);
     Date toDate = fmt1.parse(endDate);
     res = requestDate.compareTo(fromDate) >= 0 && requestDate.compareTo(toDate) <=0;
    }catch(ParseException pex){
        pex.printStackTrace();
    }
    return res;
   }
 }

class NotImplementedError extends Error {
  constructor(message) {
    super(message);
    this.message = message;
  }
}
NotImplementedError.prototype.name = 'NotImplementedError';
module.exports = NotImplementedError;

and

try {
  var e = new NotImplementedError("NotImplementedError message");
  throw e;
} catch (ex1) {
  console.log(ex1.stack);
  console.log("ex1 instanceof NotImplementedError = " + (ex1 instanceof NotImplementedError));
  console.log("ex1 instanceof Error = " + (ex1 instanceof Error));
  console.log("ex1.name = " + ex1.name);
  console.log("ex1.message = " + ex1.message);
}

It is just a class representation of this answer.

output

NotImplementedError: NotImplementedError message
  ...stacktrace
ex1 instanceof NotImplementedError = true
ex1 instanceof Error = true
ex1.name = NotImplementedError
ex1.message = NotImplementedError message

Thx for the answer!

raiserror() works fine but you shouldn't forget the return statement otherwise the script continues without error! (hense the raiserror isn't a "throwerror" ;-)) and of course doing a rollback if necessary!

raiserror() is nice to tell the person who executes the script that something went wrong.

As simple as joining lists in python itself.

ansible -m debug -a msg="{{ '-'.join(('list', 'joined', 'together')) }}" localhost

localhost | SUCCESS => {
  "msg": "list-joined-together" }

Works the same way using variables:

ansible -m debug -a msg="{{ '-'.join((var1, var2, var3)) }}" localhost

it's quite handy with {data.table} and {stringr}

library(data.table)
library(stringr)

x[, lapply(.SD, function(xx) {str_replace_na(xx, 0)})]

FYI

str = "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a".force_encoding('ASCII-8BIT')
puts CGI.escape str


=> "%124Vx%9A%BC%DE%F1%23Eg%89%AB%CD%EF%124Vx%9A"

Here are two solutions:

Select count(columnname) as countofNotNulls, count(isnull(columnname,1))-count(columnname) AS Countofnulls from table name

OR

Select count(columnname) as countofNotNulls, count(*)-count(columnname) AS Countofnulls from table name

r+ is the canonical mode for reading and writing at the same time. This is not different from using the fopen() system call since file() / open() is just a tiny wrapper around this operating system call.

if(str.length == 0 || [str isKindOfClass: [NSNull class]]){
    NSLog(@"String is empty");
}
else{
    NSLog(@"String is not empty");
}    

This will eliminate the error and is type safe:

this.DNATranscriber[character as keyof typeof DNATranscriber]

The solution posted by @Linga: "Get-ChildItem -Recurse 'directory_path' | Measure-Object -Property Length -Sum" is nice and short. However, it only computes the size of 'directory_path', without sub-directories.
Here is a simple solution for listing all sub-directory sizes. With a little pretty-printing added.
(Note: use the -File option to avoid errors for empty sub-directories)

foreach ($d in gci -Directory -Force) {
  '{0:N0}' -f ((gci $d -File -Recurse -Force | measure length -sum).sum) + "`t`t$d" 
}

You can access the stack (stacktrace in Opera) properties of an Error instance even if you threw it. The thing is, you need to make sure you use throw new Error(string) (don't forget the new instead of throw string.

Example:

try {
    0++;
} catch (e) {
    var myStackTrace = e.stack || e.stacktrace || "";
}

Our first thought is that the site is down or the like, but the truth is that this is not the problem or disability. Nor is it a problem because a simple connection when tested under Firefox, Opera or services Explorer open as normal.

The error in Chrome displays a sign that says "This site is not available" and clarification with the legend "Error 15 (net :: ERR_SOCKET_NOT_CONNECTED): Unknown error". The error is quite usual in Google Chrome, more precisely in its updates, and its workaround is to restart the computer.

As partial solutions are not much we offer a tutorial for you solve the fault in less than a minute. To avoid this problem and ensure that services are normally open in Google Chrome should insert the following into the address bar: chrome: // net-internals (then give "Enter"). They then have to go to the "Socket" in the left menu and choose "Flush Socket Pools" (look at the following screenshots to guide http://www.fixotip.com/how-to-fix-error-waiting-for-available-sockets-in-google-chrome/) This has the problem solved and no longer will experience problems accessing Gmail, Google or any of the services of the Mountain View giant. I hope you found it useful and share the tutorial with whom they need or social networks: Facebook, Twitter or Google+.

If your real and imaginary parts are the slices along the last dimension and your array is contiguous along the last dimension, you can just do

A.view(dtype=np.complex128)

If you are using single precision floats, this would be

A.view(dtype=np.complex64)

Here is a fuller example

import numpy as np
from numpy.random import rand
# Randomly choose real and imaginary parts.
# Treat last axis as the real and imaginary parts.
A = rand(100, 2)
# Cast the array as a complex array
# Note that this will now be a 100x1 array
A_comp = A.view(dtype=np.complex128)
# To get the original array A back from the complex version
A = A.view(dtype=np.float64)

If you want to get rid of the extra dimension that stays around from the casting, you could do something like

A_comp = A.view(dtype=np.complex128)[...,0]

This works because, in memory, a complex number is really just two floating point numbers. The first represents the real part, and the second represents the imaginary part. The view method of the array changes the dtype of the array to reflect that you want to treat two adjacent floating point values as a single complex number and updates the dimension accordingly.

This method does not copy any values in the array or perform any new computations, all it does is create a new array object that views the same block of memory differently. That makes it so that this operation can be performed much faster than anything that involves copying values. It also means that any changes made in the complex-valued array will be reflected in the array with the real and imaginary parts.

It may also be a little trickier to recover the original array if you remove the extra axis that is there immediately after the type cast. Things like A_comp[...,np.newaxis].view(np.float64) do not currently work because, as of this writing, NumPy doesn't detect that the array is still C-contiguous when the new axis is added. See this issue. A_comp.view(np.float64).reshape(A.shape) seems to work in most cases though.

There is no direct method to draw a triangle. You can use drawPolygon() method for this. It takes three parameters in the following form: drawPolygon(int x[],int y[], int number_of_points); To draw a triangle: (Specify the x coordinates in array x and y coordinates in array y and number of points which will be equal to the elements of both the arrays.Like in triangle you will have 3 x coordinates and 3 y coordinates which means you have 3 points in total.) Suppose you want to draw the triangle using the following points:(100,50),(70,100),(130,100) Do the following inside public void paint(Graphics g):

int x[]={100,70,130};
int y[]={50,100,100};
g.drawPolygon(x,y,3);

Similarly you can draw any shape using as many points as you want.

In my case, I got a similar error:

An unhandled exception was thrown by the application. System.ArgumentException: Format of the initialization string does not conform to specification starting at index 91.

I change my connection string from:

Server=.;Database=dbname;User Id=myuserid;Password=mypassword"

to:

Server=.;Database=dbname;User Id=myuserid;Password='mypassword'"

and it works, I added single quotes to the password.

I had this issue, until I discovered that in WPF4, you can simulate your own keyframe image animations. First, split your animation into a series of images, title them something like "Image1.gif", "Image2,gif", and so on. Import those images into your solution resources. I'm assuming you put them in the default resource location for images.

You are going to use the Image control. Use the following XAML code. I've removed the non-essentials.

<Image Name="Image1">
   <Image.Triggers>
      <EventTrigger RoutedEvent="Image.Loaded"
         <EventTrigger.Actions>
            <BeginStoryboard>
               <Storyboard>
                   <ObjectAnimationUsingKeyFrames Duration="0:0:1" Storyboard.TargetProperty="Source" RepeatBehavior="Forever">

                            <BitmapImage UriSource="Images/Image1.gif"/>
                         </DiscreteObjectKeyFrame.Value>
                      </DiscreteObjectKeyFrames>
                     <DiscreteObjectKeyFrames KeyTime="0:0:0.25">
                        <DiscreteObjectKeyFrame.Value>

                        </DiscreteObjectKeyFrame.Value>
                     </DiscreteObjectKeyFrames>
                     <DiscreteObjectKeyFrames KeyTime="0:0:0.5">
                        <DiscreteObjectKeyFrame.Value>
                           <BitmapImage UriSource="Images/Image3.gif"/>
                        </DiscreteObjectKeyFrame.Value>

                        </DiscreteObjectKeyFrame.Value>
                     </DiscreteObjectKeyFrames>
                     <DiscreteObjectKeyFrames KeyTime="0:0:1">
                        <DiscreteObjectKeyFrame.Value>
                           <BitmapImage UriSource="Images/Image5.gif"/>
                        </DiscreteObjectKeyFrame.Value>
                     </DiscreteObjectKeyFrames>

JQuery load works, but it will strip out javascript and other elements from the source page. This makes sense because you might not want to introduce bad script on your page. I think this is a limitation and since you are doing a whole page and not just a div on the source page, you might not want to use it. (I am not sure about css, but I think it would also get stripped)

In this example, if you put a tag around the body of your source page, it will grab anything in between the tags and won't strip anything out. I wrap my source page with and .

This solution will grab everything between the above delimiters. I feel it is a much more robust solution than a simple load.

  var content = $('.contentDiv');
    content.load(urlAddress, function (response, status, xhr) {
        var fullPageTextAsString = response;
        var pageTextBetweenDelimiters = fullPageTextAsString.substring(fullPageTextAsString.indexOf("<jqueryloadmarkerstart />"), fullPageTextAsString.indexOf("<jqueryloadmarkerend />"));
        content.html(pageTextBetweenDelimiters);
    });

Check if the snippets have <tabTrigger> attributes that start with special characters. If they do, they won't show up in the autocomplete box. This is currently a problem on Windows with the available jQuery plugins.

If you only use OpenFileDialog, you can capture the FileName, SafeFileName, then subtract to get folder path:

exampleFileName = ofd.SafeFileName;
exampleFileNameFull = ofd.FileName;
exampleFileNameFolder = ofd.FileNameFull.Replace(ofd.FileName, "");

I used Mike Wasson's answer before I updated all the NuGets in my webapi mvc4 project. Once I did, I had to re-write the file upload action:

    public Task<HttpResponseMessage> Upload(int id)
    {
        HttpRequestMessage request = this.Request;
        if (!request.Content.IsMimeMultipartContent())
        {
            throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.UnsupportedMediaType));
        }

        string root = System.Web.HttpContext.Current.Server.MapPath("~/App_Data/uploads");
        var provider = new MultipartFormDataStreamProvider(root);

        var task = request.Content.ReadAsMultipartAsync(provider).
            ContinueWith<HttpResponseMessage>(o =>
            {
                FileInfo finfo = new FileInfo(provider.FileData.First().LocalFileName);

                string guid = Guid.NewGuid().ToString();

                File.Move(finfo.FullName, Path.Combine(root, guid + "_" + provider.FileData.First().Headers.ContentDisposition.FileName.Replace("\"", "")));

                return new HttpResponseMessage()
                {
                    Content = new StringContent("File uploaded.")
                };
            }
        );
        return task;
    }

Apparently BodyPartFileNames is no longer available within the MultipartFormDataStreamProvider.

A minor addition to the answers already posted: object files not compiled to be position independent are relocatable; they contain relocation table entries.

These entries allow the loader (that bit of code that loads a program into memory) to rewrite the absolute addresses to adjust for the actual load address in the virtual address space.

An operating system will try to share a single copy of a "shared object library" loaded into memory with all the programs that are linked to that same shared object library.

Since the code address space (unlike sections of the data space) need not be contiguous, and because most programs that link to a specific library have a fairly fixed library dependency tree, this succeeds most of the time. In those rare cases where there is a discrepancy, yes, it may be necessary to have two or more copies of a shared object library in memory.

Obviously, any attempt to randomize the load address of a library between programs and/or program instances (so as to reduce the possibility of creating an exploitable pattern) will make such cases common, not rare, so where a system has enabled this capability, one should make every attempt to compile all shared object libraries to be position independent.

Since calls into these libraries from the body of the main program will also be made relocatable, this makes it much less likely that a shared library will have to be copied.

If you're looking for a document-level key event handling, then binding it during componentDidMount is the best way (as shown by Brad Colthurst's codepen example):

class ActionPanel extends React.Component {
  constructor(props){
    super(props);
    this.escFunction = this.escFunction.bind(this);
  }
  escFunction(event){
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }
  componentDidMount(){
    document.addEventListener("keydown", this.escFunction, false);
  }
  componentWillUnmount(){
    document.removeEventListener("keydown", this.escFunction, false);
  }
  render(){
    return (   
      <input/>
    )
  }
}

Note that you should make sure to remove the key event listener on unmount to prevent potential errors and memory leaks.

EDIT: If you are using hooks, you can use this useEffect structure to produce a similar effect:

const ActionPanel = (props) => {
  const escFunction = useCallback((event) => {
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }, []);

  useEffect(() => {
    document.addEventListener("keydown", escFunction, false);

    return () => {
      document.removeEventListener("keydown", escFunction, false);
    };
  }, []);

  return (   
    <input />
  )
};

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

Never and ever for the sake of your own good, name the folders or files with symbols like "-" or "_". If you did so, you may face few issues. like mine, say, though your command for importing is correct, you wont be able to successfully import the desired files which are available inside such named folders.

Invalid Folder namings as follows:

• Generic-Classes-Folder
• Generic_Classes_Folder

valid Folder namings for above:

• GenericClassesFolder or Genericclassesfolder or genericClassesFolder (or like this without any spaces or special symbols among the words)

consider the file structure.

   . Check

What I wanted to do?

• from testFile.py, I wanted to import the 'targetClass.py' file inside the Generic-Class-Folder file to use the function named "functionExecute" in 'targetClass.py' file

What command I did?

• from 'testFile.py', wrote command, from Core.Generic-Class-Folder.targetClass import functionExecute
• Got errors like SyntaxError: invalid syntax

Tried many searches and viewed many stackoverflow questions and unable to decide what went wrong. I cross checked my files multiple times, i used __init__.py file, inserted environment path and hugely worried what went wrong......

And after a long long long time, i figured this out while talking with a friend of mine. I am little stupid to use such naming conventions. I should never use space or special symbols to define a name for any folder or file. So, this is what I wanted to convey. Have a good day!

(sorry for the huge post over this... just letting my frustrations go.... :) Thanks!)

Delegate and Live are easy to use but if you won't have any more li:s added dynamically you could use event delagation with normal bind/click as well. There should be some performance gain using this method since the DOM won't have to be monitored for new matching elements. Haven't got any actual numbers but it makes sense :)

$("#wizard").click(function (e) {
    var source = $(e.target);
    if(source.is("li")){
        // alert index of li relative to ul parent
        alert(source.index());
    }
});

You could test it at jsFiddle: http://jsfiddle.net/jimmysv/4Sfdh/1/

The accepted answer work when you have a single line string(the email) but if you have a

multiline string, the error will remain.

Please look into this matter:

<!-- start: definition-->
@{
    dynamic item = new System.Dynamic.ExpandoObject();
    item.MultiLineString = @"a multi-line
                             string";
    item.SingleLineString = "a single-line string";
}
<!-- end: definition-->
<a href="#" onclick="Getinfo('@item.MultiLineString')">6/16/2016 2:02:29 AM</a>
<script>
    function Getinfo(text) {
        alert(text);
    }
</script>

Change the single-quote(') to backtick(`) in Getinfo as bellow and error will be fixed:

<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>

How do you disable the unused variable warnings coming out of gcc?
I'm getting errors out of boost on windows and I do not want to touch the boost code...

You visit Boost's Trac and file a bug report against Boost.

Your application is not responsible for clearing library warnings and errors. The library is responsible for clearing its own warnings and errors.

I may be late but still...

This answer is based on removing and adding views dynamically

To disable scrolling:

View child = scoll.getChildAt(0);// since scrollView can only have one direct child
ViewGroup parent = (ViewGroup) scroll.getParent();
scroll.removeView(child); // remove child from scrollview
parent.addView(child,parent.indexOfChild(scroll));// add scroll child at the position of scrollview
parent.removeView(scroll);// remove scrollView from parent

To enable ScrollView just reverse the process

I have not compiled this as it is meant for a proof of concept. This is how I have implemented a Progress bar for database access in the past. This example shows access to a SQLite database using the System.Data.SQLite module

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{   
    // Get the BackgroundWorker that raised this event.
    BackgroundWorker worker = sender as BackgroundWorker;
    using(SQLiteConnection cnn = new SQLiteConnection("Data Source=MyDatabase.db"))
    {
        cnn.Open();
        int TotalQuerySize = GetQueryCount("Query", cnn); // This needs to be implemented and is not shown in example
        using (SQLiteCommand cmd = cnn.CreateCommand())
        {
            cmd.CommandText = "Query is here";
            using(SQLiteDataReader reader = cmd.ExecuteReader())
            {
                int i = 0;
                while(reader.Read())
                {
                    // Access the database data using the reader[].  Each .Read() provides the next Row
                    if(worker.WorkerReportsProgress) worker.ReportProgress(++i * 100/ TotalQuerySize);
                }
            }
        }
    }
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    this.progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // Notify someone that the database access is finished.  Do stuff to clean up if needed
    // This could be a good time to hide, clear or do somthign to the progress bar
}

public void AcessMySQLiteDatabase()
{
    BackgroundWorker backgroundWorker1 = new BackgroundWorker();
    backgroundWorker1.DoWork += 
        new DoWorkEventHandler(backgroundWorker1_DoWork);
    backgroundWorker1.RunWorkerCompleted += 
        new RunWorkerCompletedEventHandler(
    backgroundWorker1_RunWorkerCompleted);
    backgroundWorker1.ProgressChanged += 
        new ProgressChangedEventHandler(
    backgroundWorker1_ProgressChanged);
}

if you want to shrink one slide for instance, add shapes to hide the unwanted background margins. you can set the shape color filling as the background (gray or black). It's "ugly" but it works

Extending Piotr's answer, if you also need a way to figure what to put in requirements.in, you can first use pip-chill to find the minimal set of required packages you have. By combining these tools, you can show the dependency reason why each package is installed. The full cycle looks like this:

1. Create virtual environment:
   $ python3 -m venv venv
2. Activate it:
   $ . venv/bin/activate
3. Install newest version of pip, pip-tools and pip-chill:
   (venv)$ pip install --upgrade pip
(venv)$ pip install pip-tools pip-chill
4. Build your project, install more pip packages, etc, until you want to save...
5. Extract minimal set of packages (ie, top-level without dependencies):
   (venv)$ pip-chill --no-version > requirements.in
6. Compile list of all required packages (showing dependency reasons):
   (venv)$ pip-compile requirements.in
7. Make sure the current installation is synchronized with the list:
   (venv)$ pip-sync

Assuming Python 3 (in Python 2, this difference is a little less well-defined) - a string is a sequence of characters, ie unicode codepoints; these are an abstract concept, and can't be directly stored on disk. A byte string is a sequence of, unsurprisingly, bytes - things that can be stored on disk. The mapping between them is an encoding - there are quite a lot of these (and infinitely many are possible) - and you need to know which applies in the particular case in order to do the conversion, since a different encoding may map the same bytes to a different string:

>>> b'\xcf\x84o\xcf\x81\xce\xbdo\xcf\x82'.decode('utf-16')
'?????'
>>> b'\xcf\x84o\xcf\x81\xce\xbdo\xcf\x82'.decode('utf-8')
'to??o?'

Once you know which one to use, you can use the .decode() method of the byte string to get the right character string from it as above. For completeness, the .encode() method of a character string goes the opposite way:

>>> 'to??o?'.encode('utf-8')
b'\xcf\x84o\xcf\x81\xce\xbdo\xcf\x82'
