I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

Keep the breaks - you're less likely to run into trouble if/when you edit the code later if the breaks are already in place.

Having said that, it's considered by many (including me) to be bad practice to return from the middle of a function. Ideally a function should have one entry point and one exit point.

My issue was that I went through my AndroidManifest.xml file and had removed the line

<uses-permission android:name="android.permission.INTERNET" />

because my app will not need internet. However, the react native debugging app does need internet access (to access the packager) Whoops. :)

You mention the most commonly implemented, which is Adjacency List: https://blogs.msdn.microsoft.com/mvpawardprogram/2012/06/25/hierarchies-convert-adjacency-list-to-nested-sets

There are other models as well, including materialized path and nested sets: http://communities.bmc.com/communities/docs/DOC-9902

Joe Celko has written a book on this subject, which is a good reference from a general SQL perspective (it is mentioned in the nested set article link above).

Also, Itzik Ben-Gann has a good overview of the most common options in his book "Inside Microsoft SQL Server 2005: T-SQL Querying".

The main things to consider when choosing a model are:

1) Frequency of structure change - how frequently does the actual structure of the tree change. Some models provide better structure update characteristics. It is important to separate structure changes from other data changes however. For example, you may want to model a company's organizational chart. Some people will model this as an adjacency list, using the employee ID to link an employee to their supervisor. This is usually a sub-optimal approach. An approach that often works better is to model the org structure separate from employees themselves, and maintain the employee as an attribute of the structure. This way, when an employee leaves the company, the organizational structure itself does not need to be changes, just the association with the employee that left.

2) Is the tree write-heavy or read-heavy - some structures work very well when reading the structure, but incur additional overhead when writing to the structure.

3) What types of information do you need to obtain from the structure - some structures excel at providing certain kinds of information about the structure. Examples include finding a node and all its children, finding a node and all its parents, finding the count of child nodes meeting certain conditions, etc. You need to know what information will be needed from the structure to determine the structure that will best fit your needs.

I know it's old, but you can:

• Create a service layer
• Move method there
• Call method in both controllers

Local variables do not get default values. Their initial values are undefined with out assigning values by some means. Before you can use local variables they must be initialized.

There is a big difference when you declare a variable at class level (as a member ie. as a field) and at method level.

If you declare a field at class level they get default values according to their type. If you declare a variable at method level or as a block (means anycode inside {}) do not get any values and remain undefined until somehow they get some starting values ie some values assigned to them.

LocalDateTime#plusHours

LocalDateTime is modelled on ISO-8601 standards and was introduced with Java-8 as part of JSR-310 implementation.

Use LocalDateTime#plusHours to get a copy of this LocalDateTime with the specified number of hours added.

import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.util.Locale;

public class Main {
    public static void main(String[] args) {
        // ZoneId.systemDefault() returns the timezone of your JVM. It is also the
        // default timezone for date-time type i.e.
        // LocalDateTime.now(ZoneId.systemDefault()) is same as LocalDateTime.now().
        // Change the timezone as per your requirement e.g. ZoneId.of("Europe/London")
        LocalDateTime ldt = LocalDateTime.now(ZoneId.systemDefault());
        System.out.println(ldt);

        LocalDateTime after8Hours = ldt.plusHours(8);
        System.out.println(after8Hours);

        // Custom format
        DateTimeFormatter dtfTimeFormat24H = DateTimeFormatter.ofPattern("dd/MM/uuuu HH:mm:ss", Locale.ENGLISH);
        DateTimeFormatter dtfTimeFormat12h = DateTimeFormatter.ofPattern("dd/MM/uuuu hh:mm:ss a", Locale.ENGLISH);
        System.out.println(dtfTimeFormat24H.format(after8Hours));
        System.out.println(dtfTimeFormat12h.format(after8Hours));
    }
}

Some important notes:

1. A date-time object is supposed to store the information about date, time, timezone etc., not about the formatting. You can format a date-time object into a String with the pattern of your choice using date-time formatting API.
   • The date-time formatting API for the modern date-time types is in the package, java.time.format e.g. java.time.format.DateTimeFormatter, java.time.format.DateTimeFormatterBuilder etc.
   • The date-time formatting API for the legacy date-time types is in the package, java.text e.g. java.text.SimpleDateFormat, java.text.DateFormat etc.
2. The java.util.Date object is not a real date-time object like the modern date-time types; rather, it represents the milliseconds from the Epoch of January 1, 1970. When you print an object of java.util.Date, its toString method returns the date-time in the JVM's timezone, calculated from this milliseconds value. If you need to print the date-time in a different timezone, you will need to set the timezone to SimpleDateFormat and obtain the formatted string from it.
3. The date-time API of java.util and their formatting API, SimpleDateFormat are outdated and error-prone. It is recommended to stop using them completely and switch to the modern date-time API.
   • For any reason, if you have to stick to Java 6 or Java 7, you can use ThreeTen-Backport which backports most of the java.time functionality to Java 6 & 7.
   • If you are working for an Android project and your Android API level is still not compliant with Java-8, check Java 8+ APIs available through desugaring and How to use ThreeTenABP in Android Project.

this in your callback function refers to the clicked element.

   $(".addressClick").click(function () {
        var addressValue = $(this).attr("href");
        alert(addressValue );
    });

Try using asort().

From documentation:

asort - Sort an array and maintain index association

Description:

bool asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )

This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant.

Seems removing .m2 directory and :

mvn install -DskipTests -T 4 resolved this issue for me.

you can add keyup event like this

template: `
  <input (keyup)="onKey($event)">
  <p>{{values}}</p>
`

in Component, code some like below

export class KeyUpComponent_v1 {
  values = '';

  onKey(event:any) { // without type info
    this.values += event.target.value + ' | ';
  }
}

Above answers are perfect. However I wanted to vibrate my app exactly twice on button click and this small information is missing here, hence posting for future readers like me. :)

We have to follow as mentioned above and the only change will be in the vibrate pattern as below,

long[] pattern = {0, 100, 1000, 300};
v.vibrate(pattern, -1); //-1 is important

This will exactly vibrate twice. As we already know

1. 0 is for delay
2. 100 says vibrate for 100ms for the first time
3. next comes delay of 1000ms
4. and post that vibrate again for 300ms

One can go on and on mentioning delay and vibration alternatively (e.g. 0, 100, 1000, 300, 1000, 300 for 3 vibrations and so on..) but remember @Dave's word use it responsibly. :)

Also note here that the repeat parameter is set to -1 which means the vibration will happen exactly as mentioned in the pattern. :)

Restart your IDE and everything will be fine

You should use Javascript animations for this - it is not possible in pure CSS, because you can't know the height of any element. Follow the instructions it has for you about javascript animation implementation, and copy slideUp and slideDown from jQuery's source.

use @Id .Worked for me.Otherwise it i will throw error.It depends on is there anything missing in your entity class or repository

The one way found is to use the geoXML3 library which is suitable for usage along with KML processor Version 3 of the Google Maps JavaScript API.

java.util.Date date= new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int month = cal.get(Calendar.MONTH);

Here's an example:

Given 2 int values, return true if one is negative and one is positive. Except if the parameter "negative" is true, then return true only if both are negative.

    public boolean posNeg(int a, int b, boolean negative) {
      if(!negative){
        return (a>0 && b<0)^(b>0 && a<0);
      }
      else return (a<0 && b<0);
    }

You could do something like:

>>> from time import gmtime, strftime
>>> strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())
'Thu, 28 Jun 2001 14:17:15 +0000'

If you want to use an older version of .net, create your own flag and cast it.

For basic cleanup and re-analyzing you can run "OPTIMIZE TABLE ...", it will compact out the overhead in the indexes and run ANALYZE TABLE too, but it's not going to re-sort them and make them as small & efficient as they could be.

https://dev.mysql.com/doc/refman/8.0/en/optimize-table.html

However, if you want the indexes completely rebuilt for best performance, you can:

1. drop / re-add indexes (obviously)
2. dump / reload the table
3. ALTER TABLE and "change" using the same storage engine
4. REPAIR TABLE (only works for MyISAM, ARCHIVE, and CSV)

https://dev.mysql.com/doc/refman/8.0/en/rebuilding-tables.html

If you do an ALTER TABLE on a field (that is part of an index) and change its type, then it will also fully rebuild the related index(es).

it is better to use json after post your resuest like below

  var clien = new RestClient("https://smple.com/");
  var request = new RestRequest("index", Method.POST);
  request.AddHeader("Sign", signinstance);    
  request.AddJsonBody(JsonConvert.SerializeObject(yourclass));
  var response = client.Execute<YourReturnclassSample>(request);
  if (response.StatusCode == System.Net.HttpStatusCode.Created)
   {
       return Ok(response.Content);
   }

It is not necessary to explicitly unlink the old symlink. You can do this:

ln -s newtarget temp
mv temp mylink

(or use the equivalent symlink and rename calls). This is better than explicitly unlinking because rename is atomic, so you can be assured that the link will always point to either the old or new target. However this will not reuse the original inode.

On some filesystems, the target of the symlink is stored in the inode itself (in place of the block list) if it is short enough; this is determined at the time it is created.

Regarding the assertion that the actual owner and group are immaterial, symlink(7) on Linux says that there is a case where it is significant:

The owner and group of an existing symbolic link can be changed using lchown(2). The only time that the ownership of a symbolic link matters is when the link is being removed or renamed in a directory that has the sticky bit set (see stat(2)).

The last access and last modification timestamps of a symbolic link can be changed using utimensat(2) or lutimes(3).

On Linux, the permissions of a symbolic link are not used in any operations; the permissions are always 0777 (read, write, and execute for all user categories), and can't be changed.

If you are using Eclipse then please note that while running on XDebug mode the magic constant __FILE__ will always be evaluated to:

xdebug://debug-eval

So the following check will return true if your session is under XDebug:

$is_xdebug = false !== strpos(__FILE__,'xdebug'); // true while on XDebug

$('#yourTextBoxId').live('change keyup paste', function(){
    if ($('#yourTextBoxId').val().length > 11) {
        $('#yourTextBoxId').val($('#yourTextBoxId').val().substr(0,10));
    }
});

I Used this along with vars and selectors caching for performance and that did the trick ..

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

For JavaScript use:

document.getElementsByClassName('select-holder')[0].placeholder = "This is my new text";

For jQuery use:

$('.select-holder')[0].placeholder = "This is my new text";

The primary key in Cassandra usually consists of two parts - Partition key and Clustering columns.

primary_key((partition_key), clustering_col )

Partition key - The first part of the primary key. The main aim of a partition key is to identify the node which stores the particular row.

CREATE TABLE phone_book ( phone_num int, name text, age int, city text, PRIMARY KEY ((phone_num, name), age);

Here, (phone_num, name) is the partition key. While inserting the data, the hash value of the partition key is generated and this value decides which node the row should go into.

Consider a 4 node cluster, each node has a range of hash values it can store. (Write) INSERT INTO phone_book VALUES (7826573732, ‘Joey’, 25, ‘New York’);

Now, the hash value of the partition key is calculated by Cassandra partitioner. say, hash value(7826573732, ‘Joey’) ? 12 , now, this row will be inserted in Node C.

(Read) SELECT * FROM phone_book WHERE phone_num=7826573732 and name=’Joey’;

Now, again the hash value of the partition key (7826573732,’Joey’) is calculated, which is 12 in our case which resides in Node C, from which the read is done.

2. Clustering columns - Second part of the primary key. The main purpose of having clustering columns is to store the data in a sorted order. By default, the order is ascending.

There can be more than one partition key and clustering columns in a primary key depending on the query you are solving.

primary_key((pk1, pk2), col 1,col2)

I personally find it easier use MySQL event scheduler than cron.

Enable it with

SET GLOBAL event_scheduler = ON;

and create an event like this:

CREATE EVENT name_of_event
ON SCHEDULE EVERY 1 DAY
STARTS '2014-01-18 00:00:00'
DO
DELETE FROM tbl_message WHERE DATEDIFF( NOW( ) ,  timestamp ) >=7;

and that's it.

Read more about the syntax here and here is more general information about it.

teach your editor to do it-

after writing "pr_" tab i get exactly

print("<pre>");
print_r($);
print("</pre>");

with the cursor just after the $

i did it on textmate by adding this snippet:

print("<pre>");
print_r(\$${1:});
print("</pre>");

The Use of Razor code @Html.Hidden or @Html.HiddenFor is similar to the following Html code

 <input type="hidden"/>

And also refer the following link

https://msdn.microsoft.com/en-us/library/system.web.mvc.html.inputextensions.hiddenfor(v=vs.118).aspx

border-width:0px;
border:none;

Will work fine.

This was also an easy way to add script and css in main.php

<script src="<?=Yii::app()->theme->baseUrl; ?>/js/bootstrap.min.js"></script>
<link href="<?=Yii::app()->theme->baseUrl; ?>/css/bootstrap.css" rel="stylesheet" type="text/css">

1) Go to (Open) Command Prompt (Press Window + R then type cmd Run this).

2) Run following commands

For all listening ports

netstat -aon | find /i "listening"

Apply port filter

netstat -aon |find /i "listening" |find "8080"

Finally with the PID we can run the following command to kill the process

3) Copy PID from result set

taskkill /F /PID

Ex: taskkill /F /PID 189

Sometimes you need to run Command Prompt with Administrator privileges

Done !!! you can start your service now.

You can also use the TimeUnit class. You could define

private static final String FORMAT = "%02d:%02d:%02d";

public static String parseTime(long milliseconds) {
      return String.format(FORMAT,
              TimeUnit.MILLISECONDS.toHours(milliseconds),
              TimeUnit.MILLISECONDS.toMinutes(milliseconds) - TimeUnit.HOURS.toMinutes(
              TimeUnit.MILLISECONDS.toHours(milliseconds)),
              TimeUnit.MILLISECONDS.toSeconds(milliseconds) - TimeUnit.MINUTES.toSeconds(
              TimeUnit.MILLISECONDS.toMinutes(milliseconds)));
   }

The saga continues with the Windows 10 version. I had to install Win Debug Tools on clean Windows 10 OS with Visual Studio 2015.

To make a long story short, just follow the instructions in the link provided by David Black. After downloading the files, instead of running the SDK installer, browse to the installers directory and execute the msi files directly.

I wonder how many man hours have been lost through the last decade because of MS sloppiness in regards to WDK/SDK installation?

Yes, there is a bool data type (which inherits from int and has only two values: True and False).

But also Python has the boolean-able concept for every object, which is used when function bool([x]) is called.

See more: object.nonzero and boolean-value-of-objects-in-python.

Please use the below line of code in script object which is there in package.json

"scripts": {
    "start": "webpack-dev-server --hot"
}

For me it worked perfectly fine.

If what you want is to have the print operation automatically change floats to only show 2 decimal places, consider writing a function to replace 'print'. For instance:

def fp(*args):  # fp means 'floating print'
    tmps = []
    for arg in args:
        if type(arg) is float: arg = round(arg, 2)  # transform only floats
        tmps.append(str(arg))
    print(" ".join(tmps)

Use fp() in place of print ...

fp("PI is", 3.14159) ... instead of ... print "PI is", 3.14159

To build on Louis's helpful answer...

Setting the User Agent in PhantomJS

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
...
caps = DesiredCapabilities.PHANTOMJS
caps["phantomjs.page.settings.userAgent"] = "whatever you want"
driver = webdriver.PhantomJS(desired_capabilities=caps)

The only minor issue is that, unlike for Firefox and Chrome, this does not return your custom setting:

driver.execute_script("return navigator.userAgent")

So, if anyone figures out how to do that in PhantomJS, please edit my answer or add a comment below! Cheers.

You could use url_for(only_path: false)

Yes. It is possible for overridden methods to have different return type .

But the limitations are that the overridden method must have a return type that is more specific type of the return type of the actual method.

All the answers have given examples of the overridden method to have a return type which is a subclass of the return type of the actual method.

For example :

public class Foo{

   //method which returns Foo
  Foo getFoo(){
      //your code         
  }

}

 public class subFoo extends Foo{

  //Overridden method which returns subclass of Foo
  @Override
  subFoo getFoo(){
      //your code         
  }

}

But this is not only limited to subclass.Even classes that implement an interface are a specific type of the interface and thus can be a return type where the interface is expected.

For example :

public interface Foo{

   //method which returns Foo
  Foo getFoo();

}

 public class Fizz implements Foo{

  //Overridden method which returns Fizz(as it implements Foo)
  @Override
  Fizz getFoo(){
      //your code         
  }

}

They are case insensitive, unless you do a binary comparison.

(.*) instead of (.)* would be a start. The latter will only capture the last character on the line.

Also, no need to escape the :.

Everyone here is talking about the similarities of the two. I am gonna point out the differences.

1. Using new Object() allows you to pass another object. The obvious outcome is that the newly created object will be set to the same reference. Here is a sample code:

   var obj1 = new Object();
   obj1.a = 1;
   var obj2 = new Object(obj1);
   obj2.a // 1
   

2. The usage is not limited to objects as in OOP objects. Other types could be passed to it too. The function will set the type accordingly. For example if we pass integer 1 to it, an object of type number will be created for us.

   var obj = new Object(1);
   typeof obj // "number"
   

3. The object created using the above method (new Object(1)) would be converted to object type if a property is added to it.

   var obj = new Object(1);
   typeof obj // "number"
   obj.a = 2;
   typeof obj // "object"
   

4. If the object is a copy of a child class of object, we could add the property without the type conversion.

   var obj = new Object("foo");
   typeof obj // "object"
   obj === "foo" // true
   obj.a = 1;
   obj === "foo" // true
   obj.a // 1
   var str = "foo";
   str.a = 1;
   str.a // undefined
   

You are pretty confused my friend. There are no LOOPS in SQL, only in PL/SQL. Here's a few examples based on existing Oracle table - copy/paste to see results:

-- Numeric FOR loop --
set serveroutput on -->> do not use in TOAD --
DECLARE
  k NUMBER:= 0;
BEGIN
  FOR i IN 1..10 LOOP
    k:= k+1;
    dbms_output.put_line(i||' '||k);
 END LOOP;
END;
/

-- Cursor FOR loop --
set serveroutput on
DECLARE
   CURSOR c1 IS SELECT * FROM scott.emp;
   i NUMBER:= 0;
BEGIN
  FOR e_rec IN c1 LOOP
  i:= i+1;
    dbms_output.put_line(i||chr(9)||e_rec.empno||chr(9)||e_rec.ename);
  END LOOP;
END;
/

-- SQL example to generate 10 rows --
SELECT 1 + LEVEL-1 idx
  FROM dual
CONNECT BY LEVEL <= 10
/

You're trying to invoke an instance method on the class it self.

You should do:

    Random rand = new Random();
    int a = 0 ; 
    while (!done) { 
        int a = rand.nextInt(10) ; 
    ....

Instead

As I told you here stackoverflow.com/questions/2694470/whats-wrong...

The not straightforward way of doing it would be granting select on each table of the database:

postgres=# grant select on db_name.table_name to read_only_user;

You could automate that by generating your grant statements from the database metadata.

in your build.gradle add the following to the end of the android node

android {
    ....
    ....

    sourceSets {
        main.java.srcDirs += 'src/main/<YOUR DIRECTORY>'
    }

}

Here are more code examples that will produce the argument null exception:

List<Myobj> myList = null;
//from this point on, any linq statement you perform on myList will throw an argument null exception
myList.ToList();
myList.GroupBy(m => m.Id);
myList.Count();
myList.Where(m => m.Id == 0);
myList.Select(m => m.Id == 0);
//etc...

$var:25%;
$foo:5px;
.selector {
    height:unquote("calc( #{$var} - #{$foo} )");
}

Okay, seems like a bit of a hack. I have got it to work using a substring, so that only the part of the string with the date (not the time) gets passed into the DATE function...

DATE(substr(SETTLEMENTDATE.VALUE,7,4)||'-'|| substr(SETTLEMENTDATE.VALUE,4,2)||'-'|| substr(SETTLEMENTDATE.VALUE,1,2))

I will still accept any answers that are better than this one!

Dim filepath as string
Sheets("Sheet 1").ChartObjects("Chart 1").Chart.Export filepath & "Name.jpg"

Slimmed down the code to the absolute minimum if needed.

I would like to add a little more explanation to @user837048's answer. on my OSX Yosemite and Galaxy S3 which is rooted and using firmware CyanogenMod 11 and KitKat I have done the below proceedings to Enable and Disable root prompt.

Please make ensure below

• On your system

  • Make sure you have installed Android SDK and you have set paths to binary files. type which adb on your shell. It must give you somewhat result. $ which adb /Applications/Android Studio.app/sdk/platform-tools/adb

• On your Mobile

  • Settings > Developer Options> Android Debugging = ON
  • Settings > Developer Options> Root Access = Apps and ADB

If you don't see Developer Options in your settings, Goto Settings > About Phone. Scroll down to Build number and tap there 7 times. I know its crazy. But believe me it works :D

Connect your phone via USB Cable. type on your computer's terminal

$ adb shell

you will see a prompt similiar, If any prompt has been shown on your mobile, to trust the connection, tap 'Always Trust' and 'OK'

shell@m0:/ $

now type

shell@m0:/ $ id
uid=2000(shell) gid=2000(shell) groups=1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats) context=u:r:shell:s0

See you are not root

Now exit from shell, which will fall back to computer's prompt

shell@m0:/ $ exit

Now activate root

$adb shell
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
root@m0:/ #

Wow.. you are root

root@m0:/ # id
uid=0(root) gid=0(root) context=u:r:shell:s0

I tried many solutions to go back to normal non root prompt. But didn't worked except @user837048's solution.

root@m0:/ # stop adbd && setprop service.adb.root 0 && start adbd &
[1] 32137
root@m0:/ #
$

This might exit you from Adb prompt to normal prompt. Now connect again.

$ adb shell
shell@m0:/ $

Well.. You are Non root

try this.

filename = Path.ChangeExtension(".blah") 

in you Case:

myfile= c:/my documents/my images/cars/a.jpg;
string extension = Path.GetExtension(myffile);
filename = Path.ChangeExtension(myfile,".blah") 

You should look this post too:

http://msdn.microsoft.com/en-us/library/system.io.path.changeextension.aspx

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

If you encountered this error while making an ad hoc deployment, this is now fixed in the XCode 7.3.1 release (May 3th, 2016) : https://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12

Changelog 7.3.1 :

• Git updated to version 2.7.4 to improve security
• Fixed an issue where turning off a capability in the Xcode editor could leave the entitlement enabled in the app bundle
• Fixed an issue that could prevent the export of an ad-hoc build from an archive
• Fixed a crash when importing localizations

As David Aldridge explained, your parentheses should start right after the sqlplus command, so it should be:

sqlplus 'test/test@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname.com )(PORT=1521)))(CONNECT_DATA=(SID=mysid))'

According to docs:

public Cursor query (String table, String[] columns, String selection, String[] selectionArgs, String groupBy, String having, String orderBy, String limit);

and your ORDER BY param means:

How to order the rows, formatted as an SQL ORDER BY clause (excluding the ORDER BY itself). Passing null will use the default sort order, which may be unordered.

So, your query will be:

 Cursor cursor = db.query(TABLE_NAME, null, null,
            null, null, null, KEY_ITEM + " DESC", null);

Using pure bash :

$ cat file.txt
US/Central - 10:26 PM (CST)
$ while read a b time x; do [[ $b == - ]] && echo $time; done < file.txt

another solution with bash regex :

$ [[ "US/Central - 10:26 PM (CST)" =~ -[[:space:]]*([0-9]{2}:[0-9]{2}) ]] &&
    echo ${BASH_REMATCH[1]}

another solution using grep and look-around advanced regex :

$ echo "US/Central - 10:26 PM (CST)" | grep -oP "\-\s+\K\d{2}:\d{2}"

another solution using sed :

$ echo "US/Central - 10:26 PM (CST)" |
    sed 's/.*\- *\([0-9]\{2\}:[0-9]\{2\}\).*/\1/'

another solution using perl :

$ echo "US/Central - 10:26 PM (CST)" |
    perl -lne 'print $& if /\-\s+\K\d{2}:\d{2}/'

and last one using awk :

$ echo "US/Central - 10:26 PM (CST)" |
    awk '{for (i=0; i<=NF; i++){if ($i == "-"){print $(i+1);exit}}}'

The other answers here are very much correct, and valuable. But sometimes you just want simple: to get a plain old parsed value at directive instantiation, without needing updates, and without messing with isolate scope. For instance, it can be handy to provide a declarative payload into your directive as an array or hash-object in the form:

my-directive-name="['string1', 'string2']"

In that case, you can cut to the chase and just use a nice basic angular.$eval(attr.attrName).

element.val("value = "+angular.$eval(attr.value));

Working Fiddle.

I Think this is the best way to do it.

REPLACE(CONVERT(NVARCHAR,CAST(WeekEnding AS DATETIME), 106), ' ', '-')

Because you do not have to use varchar(11) or varchar(10) that can make problem in future.

An instance might be corrupted or not updated properly.

Try these Commands:

C:\>sqllocaldb stop MSSQLLocalDB
LocalDB instance "MSSQLLocalDB" stopped.
 
C:\>sqllocaldb delete MSSQLLocalDB
LocalDB instance "MSSQLLocalDB" deleted.
 
C:\>sqllocaldb create MSSQLLocalDB
LocalDB instance "MSSQLLocalDB" created with version 13.0.1601.5.
 
C:\>sqllocaldb start MSSQLLocalDB
LocalDB instance "MSSQLLocalDB" started.

I've written an extension method for this purpose:

public static byte[] FromBase64Bytes(this byte[] base64Bytes)
{
    string base64String = Encoding.UTF8.GetString(base64Bytes, 0, base64Bytes.Length);
    return Convert.FromBase64String(base64String);
}

Call it like this:

byte[] base64Bytes = .......
byte[] regularBytes = base64Bytes.FromBase64Bytes();

I hope it helps someone.

If you use vue cli with the Webpack template (default config), you can create and add your environment variables to a .env file.

The variables will automatically be accessible under process.env.variableName in your project. Loaded variables are also available to all vue-cli-service commands, plugins and dependencies.

You have a few options, this is from the Environment Variables and Modes documentation:

.env                # loaded in all cases
.env.local          # loaded in all cases, ignored by git
.env.[mode]         # only loaded in specified mode
.env.[mode].local   # only loaded in specified mode, ignored by git

Your .env file should look like this:

VUE_APP_MY_ENV_VARIABLE=value
VUE_APP_ANOTHER_VARIABLE=value

It is my understanding that all you need to do is create the .env file and add your variables then you're ready to go! :)

As noted in comment below: If you are using Vue cli 3, only variables that start with VUE_APP_ will be loaded.

Don't forget to restart serve if it is currently running.

Is there a reason why you can't use the Excel ODBC connection to read and write to Excel? For example, I've used the following code to read from an Excel file row by row like a database:

private DataTable LoadExcelData(string fileName)
{
  string Connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=1\";";

  OleDbConnection con = new OleDbConnection(Connection);

  OleDbCommand command = new OleDbCommand();

  DataTable dt = new DataTable(); OleDbDataAdapter myCommand = new OleDbDataAdapter("select * from [Sheet1$] WHERE LastName <> '' ORDER BY LastName, FirstName", con);

  myCommand.Fill(dt);

  Console.WriteLine(dt.Rows.Count);

  return dt;
}

You can write to the Excel "database" the same way. As you can see, you can select the version number to use so that you can downgrade Excel versions for the machine with Excel 2003. Actually, the same is true for using the Interop. You can use the lower version and it should work with Excel 2003 even though you only have the higher version on your development PC.

jQuery Validation Plugin already implements min and max rules, we just need to create an adapter for our custom attribute:

public class MaxAttribute : ValidationAttribute, IClientValidatable
{
    private readonly int maxValue;

    public MaxAttribute(int maxValue)
    {
        this.maxValue = maxValue;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var rule = new ModelClientValidationRule();

        rule.ErrorMessage = ErrorMessageString, maxValue;

        rule.ValidationType = "max";
        rule.ValidationParameters.Add("max", maxValue);
        yield return rule;
    }

    public override bool IsValid(object value)
    {
        return (int)value <= maxValue;
    }
}

Adapter:

$.validator.unobtrusive.adapters.add(
   'max',
   ['max'],
   function (options) {
       options.rules['max'] = parseInt(options.params['max'], 10);
       options.messages['max'] = options.message;
   });

Min attribute would be very similar.

Okay so what helped me was iterating backwards. I was trying to remove an entry from a list but iterating upwards and it screwed up the loop because the entry didn't exist anymore:

for (int x = myList.Count - 1; x > -1; x--)
{
    myList.RemoveAt(x);
}

You need to set your local branch to track the remote branch, which it won't do automatically if they have different capitalizations.

Try:

git branch --set-upstream downloadmanager origin/DownloadManager
git pull

UPDATE:

'--set-upstream' option is no longer supported.

git branch --set-upstream-to downloadmanager origin/DownloadManager
git pull

relate to this suggestion : https://stackoverflow.com/a/20215481/3080835

also i had to add this to Application element in the Manifest:

<meta-data 
           android:name="com.google.android.gms.version" 
           android:value="@integer/google_play_services_version" />

and it worked perfectly.

Here is a solution using a generic template type:

public static <T> List<T> copyList(List<T> source) {
    List<T> dest = new ArrayList<T>();
    for (T item : source) { dest.add(item); }
    return dest;
}

Well you could use the line-clamp function in CSS3.

p {
    overflow: hidden;
    text-overflow: ellipsis;
    display: -webkit-box;
    line-height: 25px;
    height: 52px;
    max-height: 52px;
    font-size: 22px;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;
}

Make sure you change the settings like you're own.

Once a dom element is created, the tag is immutable, I believe. You'd have to do something like this:

$(this).replaceWith($('<h5>' + this.innerHTML + '</h5>'));

I changed my layout XML file name and found out later that of the XML file (widget provider in this case) still refers to the old layout XML which doesn't exist, and that prevented the auto generation/correction of R class.

Two ways.

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

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

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

ii. Create a parent controller and define it there

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

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

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

int count = 0;    
using (new SqlConnection connection = new SqlConnection("connectionString"))
{
    sqlCommand cmd = new SqlCommand("SELECT COUNT(*) FROM table_name", connection);
    connection.Open();
    count = (int32)cmd.ExecuteScalar();
}

Attention: this is an extremely rough and oversimplified sketch, assuming the simplest possible HTTP request (no HTTPS, no HTTP2, no extras), simplest possible DNS, no proxies, single-stack IPv4, one HTTP request only, a simple HTTP server on the other end, and no problems in any step. This is, for most contemporary intents and purposes, an unrealistic scenario; all of these are far more complex in actual use, and the tech stack has become an order of magnitude more complicated since this was written. With this in mind, the following timeline is still somewhat valid:

1. browser checks cache; if requested object is in cache and is fresh, skip to #9
2. browser asks OS for server's IP address
3. OS makes a DNS lookup and replies the IP address to the browser
4. browser opens a TCP connection to server (this step is much more complex with HTTPS)
5. browser sends the HTTP request through TCP connection
6. browser receives HTTP response and may close the TCP connection, or reuse it for another request
7. browser checks if the response is a redirect or a conditional response (3xx result status codes), authorization request (401), error (4xx and 5xx), etc.; these are handled differently from normal responses (2xx)
8. if cacheable, response is stored in cache
9. browser decodes response (e.g. if it's gzipped)
10. browser determines what to do with response (e.g. is it a HTML page, is it an image, is it a sound clip?)
11. browser renders response, or offers a download dialog for unrecognized types

Again, discussion of each of these points have filled countless pages; take this only as a summary, abridged for the sake of clarity. Also, there are many other things happening in parallel to this (processing typed-in address, speculative prefetching, adding page to browser history, displaying progress to user, notifying plugins and extensions, rendering the page while it's downloading, pipelining, connection tracking for keep-alive, cookie management, checking for malicious content etc.) - and the whole operation gets an order of magnitude more complex with HTTPS (certificates and ciphers and pinning, oh my!).

Finally solved issue of reinitialization of select2 after ajax call.

You can call this in success function of ajax.

Note : Don't forget to replace ".selector" to your class of <select class="selector"> element.

jQuery('.select2-container').remove();

jQuery('.selector').select2({
   placeholder: "Placeholder text",
   allowClear: true
});

jQuery('.select2-container').css('width','100%');

innerText has been added to Firefox and should be available in the FF45 release: https://bugzilla.mozilla.org/show_bug.cgi?id=264412

A draft spec has been written and is expected to be incorporated into the HTML living standard in the future: http://rocallahan.github.io/innerText-spec/, https://github.com/whatwg/html/issues/465

Note that currently the Firefox, Chrome and IE implementations are all incompatible. Going forward, we can probably expect Firefox, Chrome and Edge to converge while old IE remains incompatible.

Hard Real-Time

The hard real-time definition considers any missed deadline to be a system failure. This scheduling is used extensively in mission critical systems where failure to conform to timing constraints results in a loss of life or property.

Examples:

• Air France Flight 447 crashed into the ocean after a sensor malfunction caused a series of system errors. The pilots stalled the aircraft while responding to outdated instrument readings. All 12 crew and 216 passengers were killed.

• Mars Pathfinder spacecraft was nearly lost when a priority inversion caused system restarts. A higher priority task was not completed on time due to being blocked by a lower priority task. The problem was corrected and the spacecraft landed successfully.

• An Inkjet printer has a print head with control software for depositing the correct amount of ink onto a specific part of the paper. If a deadline is missed then the print job is ruined.

Firm Real-Time

The firm real-time definition allows for infrequently missed deadlines. In these applications the system can survive task failures so long as they are adequately spaced, however the value of the task's completion drops to zero or becomes impossible.

Examples:

• Manufacturing systems with robot assembly lines where missing a deadline results in improperly assembling a part. As long as ruined parts are infrequent enough to be caught by quality control and not too costly, then production continues.

• A digital cable set-top box decodes time stamps for when frames must appear on the screen. Since the frames are time order sensitive a missed deadline causes jitter, diminishing quality of service. If the missed frame later becomes available it will only cause more jitter to display it, so it's useless. The viewer can still enjoy the program if jitter doesn't occur too often.

Soft Real-Time

The soft real-time definition allows for frequently missed deadlines, and as long as tasks are timely executed their results continue to have value. Completed tasks may have increasing value up to the deadline and decreasing value past it.

Examples:

• Weather stations have many sensors for reading temperature, humidity, wind speed, etc. The readings should be taken and transmitted at regular intervals, however the sensors are not synchronized. Even though a sensor reading may be early or late compared with the others it can still be relevant as long as it is close enough.

• A video game console runs software for a game engine. There are many resources that must be shared between its tasks. At the same time tasks need to be completed according to the schedule for the game to play correctly. As long as tasks are being completely relatively on time the game will be enjoyable, and if not it may only lag a little.

The biggest problem with a batch script is handling rollback when the user clicks cancel (or something goes wrong during your install). The correct way to handle this scenario is to create a CustomAction that adds temporary rows to the RemoveFiles table. That way the Windows Installer handles the rollback cases for you. It is insanely simpler when you see the solution.

Anyway, to have an action only execute during uninstall add a Condition element with:

REMOVE ~= "ALL"

the ~= says compare case insensitive (even though I think ALL is always uppercaesd). See the MSI SDK documentation about Conditions Syntax for more information.

PS: There has never been a case where I sat down and thought, "Oh, batch file would be a good solution in an installation package." Actually, finding an installation package that has a batch file in it would only encourage me to return the product for a refund.

Option 1: Drop Files Into Project's libs/directory

The relevant build.gradle file will then update automatically.

Option 2: Modify build.gradle File Manually

Open your build.gradle file and add a new build rule to the dependencies closure. For example, if you wanted to add Google Play Services, your project's dependencies section would look something like this:

dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     compile 'com.google.android.gms:play-services:6.5.+'
   }

Option 3: Use Android Studio's User Interface

In the Project panel, Control + click the module you want to add the dependency to and select Open Module Settings.

Select the Dependencies tab, followed by the + button in the bottom-left corner. You can choose from the following list of options:

• Library Dependency
• File Dependency
• Module Dependency

You can then enter more information about the dependency you want to add to your project. For example, if you choose Library Dependency, Android Studio displays a list of libraries for you to choose from.

Once you've added your dependency, check your module-level build.gradle file. It should have automatically updated to include the new dependency.

Source

Using linear algebra, there exist algorithms that achieve better complexity than the naive O(n³). Solvay Strassen algorithm achieves a complexity of O(n^2.807) by reducing the number of multiplications required for each 2x2 sub-matrix from 8 to 7.

The fastest known matrix multiplication algorithm is Coppersmith-Winograd algorithm with a complexity of O(n^2.3737). Unless the matrix is huge, these algorithms do not result in a vast difference in computation time. In practice, it is easier and faster to use parallel algorithms for matrix multiplication.

For some 'Eclipse Marketplace' plugins Uninstall may not work. (Ex: SonarLint v5)

So Try,

Help -> About Eclipse -> Installation details

• search the plugin name in 'Installed Software'

• Select plugin name and Uninstall it

Additional Detail

To fix plugin errors, after the uninstall revert back older version of plugin,

Help -> install new software..

• Get plugin url from Google search and Add it (Example: https://eclipse-uc.sonarlint.org)

• Select and install older versions of the Plugin. This will fix most of the plugin problems.

In Eclipse Photon navigate to Windows > Preferences > Maven > User Settings > User Setting

For "User settings" Browse to the settings.xml of the maven. ex. in my case maven it is located on the path C:\Program Files\Apache Software Distribution\apache-maven-3.5.4\conf\Settings.xml

Depending on the Settings.xml the Local Repository gets automatically configured to the specified location.

And if you just want to get the directory name and no need for the filename coming with it, then you can do that in the following conventional way using os Python module.

>>> import os
>>> f = open('/Users/Desktop/febROSTER2012.xls')
>>> os.path.dirname(f.name)
>>> '/Users/Desktop/'

This way you can get hold of the directory structure.

Today, I had the same problem. My eclipse refused to start. When I double clicked on Eclipse icon I was able to see splashscreen for a second and then nothing happen. Tried most of the solutions here: removed lock file, renamed workspace, tried to start Eclipse with different clean parameters. I even put a new copy of Eclispe and tried to start with a new workspace. Nothing!

My logs were showing bunch of errors from yesterday when my workstation was rebooted at 17:45.

!ENTRY org.eclipse.ui.workbench 4 2 2014-12-17 17:45:12.178
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
!STACK 0
java.lang.NullPointerException

In the end this very simple change (look below) saved my Eclipse together with my workspace!

SOLUTION:

I edited eclipse.ini and added following line:

-vm
C:\Program Files\Java\jdk1.6.0_26\bin\javaw.exe

Eclipse has started again with all my projects inside! I hope this can help.

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

Windows XP:

Be sure to set to click the settings button for each of the items in the "Dial-up and Virtual Private Network settings" listbox in the "Connections" tab of the "Internet Options" control panel applet.

I noticed that Fiddler would stop using the "LAN settings" configuration once I connected to my VPN. Even if the traffic wasn't going through the VPN.

Select [Column Name] into [New Table] from [Source Table]

I believe that the password expiration behavior, by default, is to never expire. However, you could set up a profile for your dev user set and set the PASSWORD_LIFE_TIME. See the orafaq for more details. You can see here for an example of one person's perspective and usage.

Just keep in mind there are 2 spaces between Aug and 26. Other wise your find command will not work.

find . -type f -exec ls -l {} \; |  egrep "Aug 26";

Figuring out dependencies for small projects is not hard. But once you start dealing with a dependency tree with hundreds of dependencies, things can easily get out of hand. (I'm speaking from experience here ...)

The other point is that if you use an IDE with incremental compilation and Maven support (like Eclipse + m2eclipse), then you should be able to set up edit/compile/hot deploy and test.

I personally don't do this because I've come to distrust this mode of development due to bad experiences in the past (pre Maven). Perhaps someone can comment on whether this actually works with Eclipse + m2eclipse.

Well, I have a tricky method for this job. The idea is as follow-

Make some invisible HTML tags like <label>, <p>, <input> etc. in HTML body and make a pattern in tag id, for example, use list index in tag id and list value at tag class name.

Here I have two lists maintenance_next[] and maintenance_block_time[] of the same length. I want to pass these two list's data to javascript using the flask. So I take some invisible label tag and set its tag name is a pattern of list index and set its class name as value at index.

{% for i in range(maintenance_next|length): %}_x000D_
<label id="maintenance_next_{{i}}" name="{{maintenance_next[i]}}" style="display: none;"></label>_x000D_
<label id="maintenance_block_time_{{i}}" name="{{maintenance_block_time[i]}}" style="display: none;"></label>_x000D_
{% endfor%}

After this, I retrieve the data in javascript using some simple javascript operation.

<script>_x000D_
var total_len = {{ total_len }};_x000D_
_x000D_
for (var i = 0; i < total_len; i++) {_x000D_
    var tm1 = document.getElementById("maintenance_next_" + i).getAttribute("name");_x000D_
    var tm2 = document.getElementById("maintenance_block_time_" + i).getAttribute("name");_x000D_
    _x000D_
    //Do what you need to do with tm1 and tm2._x000D_
    _x000D_
    console.log(tm1);_x000D_
    console.log(tm2);_x000D_
}_x000D_
</script>

I have mentioned the configuration changes needed for the increase of heap size in Windows or Linux environments.

Linux:

bin/standalone.conf

Check for the following line,

JAVA_OPTS

and change it accordingly to suit your heap size needs

-Xms1303m: initial heap size in megabytes
-Xmx1303m: maximum heap size in megabytes

JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"

Windows:

bin/standalone.conf.bat

JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"

Now restart the server and it will work without prompting any heap size errors.

For more information you can refer this link below.

https://access.redhat.com/documentation/en-us/jboss_enterprise_application_platform/5/html/getting_started_guide/adjust_memory_settings

This is one of the ways:

String toDate = "05/11/2010";

if (new SimpleDateFormat("MM/dd/yyyy").parse(toDate).getTime() / (1000 * 60 * 60 * 24) >= System.currentTimeMillis() / (1000 * 60 * 60 * 24)) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

A bit more easy interpretable:

String toDateAsString = "05/11/2010";
Date toDate = new SimpleDateFormat("MM/dd/yyyy").parse(toDateAsString);
long toDateAsTimestamp = toDate.getTime();
long currentTimestamp = System.currentTimeMillis();
long getRidOfTime = 1000 * 60 * 60 * 24;
long toDateAsTimestampWithoutTime = toDateAsTimestamp / getRidOfTime;
long currentTimestampWithoutTime = currentTimestamp / getRidOfTime;

if (toDateAsTimestampWithoutTime >= currentTimestampWithoutTime) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Oh, as a bonus, the JodaTime's variant:

String toDateAsString = "05/11/2010";
DateTime toDate = DateTimeFormat.forPattern("MM/dd/yyyy").parseDateTime(toDateAsString);
DateTime now = new DateTime();

if (!toDate.toLocalDate().isBefore(now.toLocalDate())) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Using canvas to display Videos

Displaying a video is much the same as displaying an image. The minor differences are to do with onload events and the fact that you need to render the video every frame or you will only see one frame not the animated frames.

The demo below has some minor differences to the example. A mute function (under the video click mute/sound on to toggle sound) and some error checking to catch IE9+ and Edge if they don't have the correct drivers.

The previous answers by user372551 is out of date (December 2010) and has a flaw in the rendering technique used. It uses the setTimeout and a rate of 33.333..ms which setTimeout will round down to 33ms this will cause the frames to be dropped every two seconds and may drop many more if the video frame rate is any higher than 30. Using setTimeout will also introduce video shearing created because setTimeout can not be synced to the display hardware.

There is currently no reliable method that can determine a videos frame rate unless you know the video frame rate in advance you should display it at the maximum display refresh rate possible on browsers. 60fps

The given top answer was for the time (6 years ago) the best solution as requestAnimationFrame was not widely supported (if at all) but requestAnimationFrame is now standard across the Major browsers and should be used instead of setTimeout to reduce or remove dropped frames, and to prevent shearing.

The example demo.

Loads a video and set it to loop. The video will not play until the you click on it. Clicking again will pause. There is a mute/sound on button under the video. The video is muted by default.

Note users of IE9+ and Edge. You may not be able to play the video format WebM as it needs additional drivers to play the videos. They can be found at tools.google.com Download IE9+ WebM support

Canvas extras

Using the canvas to render video gives you additional options in regard to displaying and mixing in fx. The following image shows some of the FX you can get using the canvas. Using the 2D API gives a huge range of creative possibilities.

Since I use underscore.js in almost every project, I would use the keys function:

var obj = {name: 'gach', hello: 'world'};
console.log(_.keys(obj));

The output of that will be:

['name', 'hello']

    string breaks = "\r\r\r";
    // Initial replacement target string for tabs
    string tabs = "\t\t\t\t\t";
    for (int index=0; index<result.Length; index++)

}

Escape characters such as \n and \r had to be removed first because they cause regexes to cease working as expected.

Moreover, to make the result string display correctly in the textbox, one might need to split it up and set textbox's Lines property instead of assigning to Text property.

this.txtResult.Lines = StripHTML(this.txtSource.Text).Split("\r".ToCharArray());

I was able to solve this issue by doing the following...

1. Go to the MySQL website for Workbench: https://dev.mysql.com/downloads/workbench/
2. Once there scroll to the bottom of the page and click on the tab that says "Development Releases"
3. Select your platform, download & install

You will likely want to uninstall any workbench packages already installed. GL!

int i = 0;
Console.WriteLine(i++); // Prints 0. Then value of "i" becomes 1.
Console.WriteLine(--i); // Value of "i" becomes 0. Then prints 0.

Does this answer your question ?

I was having the same problem in an application that I was maintaining, among all the adjustments to prepare the environment, I also spent almost an hour banging my head with this error "ORA-01036: illegal variable name / number" until I found out that the application connection was pointed to an outdated database, so the application passed two more parameters to the outdated database procedure causing the error.

When I read your question, I thought your were on Oracle DB until I saw the tag 'MySQL'. Anyway, for people working with Oracle here is the way:

SELECT *
FROM table
where timestamp = to_timestamp('21.08.2017 09:31:57', 'dd-mm-yyyy hh24:mi:ss');

for word in d:
    if d in paid[j]:
         do_something()

will try all the words in the list d and check if they can be found in the string paid[j].

This is not very efficient since paid[j] has to be scanned again for each word in d. You could also use two sets, one composed of the words in the sentence, one of your list, and then look at the intersection of the sets.

sentence = "words don't come easy"
d = ["come", "together", "easy", "does", "it"]

s1 = set(sentence.split())
s2 = set(d)

print (s1.intersection(s2))

Output:

{'come', 'easy'}

Put your CSS in your bundle's Resource/public/css directory, and your images in say Resource/public/img.

Change assetic paths to the form 'bundles/mybundle/css/*.css', in your layout.

In config.yml, add rule css_rewrite to assetic:

assetic:
    filters:
        cssrewrite:
            apply_to: "\.css$"

Now install assets and compile with assetic:

$ rm -r app/cache/* # just in case
$ php app/console assets:install --symlink
$ php app/console assetic:dump --env=prod

This is good enough for the development box, and --symlink is useful, so you don't have to reinstall your assets (for example, you add a new image) when you enter through app_dev.php.

For the production server, I just removed the '--symlink' option (in my deployment script), and added this command at the end:

$ rm -r web/bundles/*/css web/bundles/*/js # all this is already compiled, we don't need the originals

All is done. With this, you can use paths like this in your .css files: ../img/picture.jpeg

Two UDF to deal with UTF-8 in T-SQL:

    while @i>0

I would think that your first question is simply a matter of scope. The ServletContext is a much more broad scoped object (the whole servlet context) than a ServletRequest, which is simply a single request. You might look to the Servlet specification itself for more detailed information.

As to how, I am sorry but I will have to leave that for others to answer at this time.

An easy way to get the first or last segment, in case you are unsure of the path length.

$segments = request()->segments();
$last  = end($segments);
$first = reset($segments);

For passing in command line parameters. For example args[0] will give you the first command line parameter, if there is one.

Assuming you have a following list my_list = [1,2,3,4,5,6,7,8,9,10] and we know that if we do max(my_list) it will return 10 and min(my_list) will return 1. Now we want to get the index of the maximum or minimum element we can do the following.

my_list = [1,2,3,4,5,6,7,8,9,10]

max_value = max(my_list) # returns 10
max_value_index = my_list.index(max_value) # retuns 9

#to get an index of minimum value

min_value = min(my_list) # returns 1
min_value_index = my_list.index(min_value) # retuns 0

To add to svick's answer, the -m option simply adds a message to your stash, and is entirely optional. Thus, the command

git stash push [paths you wish to stash]

is perfectly valid. So for instance, if I want to only stash changes in the src/ directory, I can just run

git stash push src/

Please try this way.

<table border="1">
    <tr>
        <th scope="col">Header</th>
        <th scope="col">Header</th>
        <th colspan="2">Header</th>
    </tr> 
    <tr>
        <td scope="row">&nbsp;</td>
        <td scope="row">&nbsp;</td>
        <td scope="col">Split this one</td>
        <td scope="col">into two columns</td>

I usually do a:

typedef enum {FALSE = 0, TRUE} boolean;

Better to use a vbs as you indicated

1. Create a simple vbs, which is a text file with a .vbs extension (see sample code below)
2. Use the Task Scheduler to run the vbs
3. Use the vbs to open the workbook at the scheduled time and then either:
   • use the Private Sub Workbook_Open() event in the ThisWorkbook module to run code when the file is opened
   • more robustly (as macros may be disabled on open), use Application.Run in the vbs to run the macro

See this example of the later approach at Running Excel on Windows Task Scheduler

sample vbs

Dim ObjExcel, ObjWB
Set ObjExcel = CreateObject("excel.application")
'vbs opens a file specified by the path below
Set ObjWB = ObjExcel.Workbooks.Open("C:\temp\rod.xlsm")
'either use the Workbook Open event (if macros are enabled), or Application.Run

ObjWB.Close False
ObjExcel.Quit
Set ObjExcel = Nothing

I wouldn't recommend using the window as some of the other answers suggest. Use this and scope accordingly.

this['yourDynamicFcnName'](arguments);

Another neat trick is calling within different scopes and using it for inheritance. Let's say you had nested the function and want access to the global window object. You could do this:

this['yourDynamicFcnName'].call(window, arguments);

You may use Fernet as follows:

from cryptography.fernet import Fernet
key = Fernet.generate_key()
f = Fernet(key)
encrypt_value = f.encrypt(b"YourString")
f.decrypt(encrypt_value)

Here is email code I used in one of my databases. I just made variables for the person I wanted to send it to, CC, subject, and the body. Then you just use the DoCmd.SendObject command. I also set it to "True" after the body so you can edit the message before it automatically sends.

Public Function SendEmail2()

Dim varName As Variant          
Dim varCC As Variant            
Dim varSubject As Variant      
Dim varBody As Variant          

varName = "[email protected]"
varCC = "[email protected], [email protected]"
'separate each email by a ','

varSubject = "Hello"
'Email subject

varBody = "Let's get ice cream this week"

'Body of the email
DoCmd.SendObject , , , varName, varCC, , varSubject, varBody, True, False
'Send email command. The True after "varBody" allows user to edit email before sending.
'The False at the end will not send it as a Template File

End Function

glBegin(GL_POLYGON);                        // Middle circle
double radius = 0.2;
double ori_x = 0.0;                         // the origin or center of circle
double ori_y = 0.0;
for (int i = 0; i <= 300; i++) {
    double angle = 2 * PI * i / 300;
    double x = cos(angle) * radius;
    double y = sin(angle) * radius;
    glVertex2d(ori_x + x, ori_y + y);
}
glEnd();

I had a similar problem, tried to delete an empty folder via windows explorer. Showed me the not empty error, so I thought I try it via admin cmd, but none of the answers here helped.

After I moved a file into the empty folder. I was able to delete the non empty folder

Use of folloing command is depreciated

There are a couple of online, offline tools how to do this:

• HAR viewer
• HAR analyser

But the one that I liked the most, is a browser extension (tried it in chrome, hopefully it works in other browsers). After installation, it appears in your apps as HAR viewer. Then you can upload you HAR file and see something like this:

You might create a View selecting the column names required by your insert statement, add an INSTEAD OF INSERT Trigger, and insert into this view.

Use @RequestParam

@RequestMapping(value="user", method = RequestMethod.GET)
public @ResponseBody Item getItem(@RequestParam("data") String itemid){

    Item i = itemDao.findOne(itemid);              
    String itemName = i.getItemName();
    String price = i.getPrice();
    return i;
}

I User this Code in my project, Useful for me.

    private void Form1_Resize(object sender, EventArgs e)
    {
        int w = MainPanel.Width; // you can use form.width when you don't use panels

        w = (w - 120)/4; // 120 because set 15px for each side of panels
                         // and put panels in FlowLayoutPanel
                         // 4 because i have 4 panel boxes
        panel1.Width = w;
        panel2.Width = w;
        panel3.Width = w;
        panel4.Width = w;
    }

Don't use quotes with <<EOF:

var=$1
sudo tee "/path/to/outfile" > /dev/null <<EOF
Some text that contains my $var
EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

If you want to add html content to your email, url encode your html code for the message body and include it in your mailto link code, but trouble is you can't set the type of the email from this link from plaintext to html, the client using the link needs their mail client to send html emails by default. In case you want to test here is the code for a simple mailto link, with an image wrapped in a link (angular style urls added for visibility):

<a href="mailto:?body=%3Ca%20href%3D%22{{ scope.url }}%22%3E%3Cimg%20src%3D%22{{ scope.url }}%22%20width%3D%22300%22%20%2F%3E%3C%2Fa%3E">

The html tags are url encoded.

If your source date format is all messed up, try something along the lines of:

select
convert(nvarchar(50),year(a.messedupDate))+'-'+
(case when len(convert(nvarchar(50),month(a.messedupDate)))=1 
    then '0'+ convert(nvarchar(50),month(a.messedupDate))+'-' 
    else convert(nvarchar(50),month(a.messedupDate)) end)+
(case when len(convert(nvarchar(50),day(a.messedupDate)))=1 
    then '0'+ convert(nvarchar(50),day(a.messedupDate))+'-'
    else convert(nvarchar(50),day(a.messedupDate)) end) 
from messytable a

You should use Linking.

Example from the docs:

class OpenURLButton extends React.Component {
  static propTypes = { url: React.PropTypes.string };
  handleClick = () => {
    Linking.canOpenURL(this.props.url).then(supported => {
      if (supported) {
        Linking.openURL(this.props.url);
      } else {
        console.log("Don't know how to open URI: " + this.props.url);
      }
    });
  };
  render() {
    return (
      <TouchableOpacity onPress={this.handleClick}>
        {" "}
        <View style={styles.button}>
          {" "}<Text style={styles.text}>Open {this.props.url}</Text>{" "}
        </View>
        {" "}
      </TouchableOpacity>
    );
  }
}

Here's an example you can try on Expo Snack:

import React, { Component } from 'react';
import { View, StyleSheet, Button, Linking } from 'react-native';
import { Constants } from 'expo';

export default class App extends Component {
  render() {
    return (
      <View style={styles.container}>
       <Button title="Click me" onPress={ ()=>{ Linking.openURL('https://google.com')}} />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    paddingTop: Constants.statusBarHeight,
    backgroundColor: '#ecf0f1',
  },
});

The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.

Thank you all for your help!

There is an object serialization module, with the serialize function you can serialize any object.

I wanted a solution for Gnu sort on Windows, but none of the above solutions worked for me on the command line.

Using Lloyd's clue, the following batch file (.bat) worked for me.

Type the tab character within the double quotes.

C:\>cat foo.bat

sort -k3 -t"    " tabfile.txt

Just to add to all the conversation. Since arrays requires consecutive memory locations to store the item, so if we create an array of references then it's not guaranteed that they will be at consecutive memory location so accessing will be a problem and hence we can't even apply all the mathematical operations on array.

.push() is a method of the Built-in Array Object

It is not related to jQuery in any way.

You are defining a literal Object with

// Object
var stuff = {};

You can define a literal Array like this

// Array
var stuff = [];

then

stuff.push(element);

Arrays actually get their bracket syntax stuff[index] inherited from their parent, the Object. This is why you are able to use it the way you are in your first example.

This is often used for effortless reflection for dynamically accessing properties

stuff = {}; // Object

stuff['prop'] = 'value'; // assign property of an 
                         // Object via bracket syntax

stuff.prop === stuff['prop']; // true

In order to run scripts, you should write the "python test.py" command in the command prompt, and not within the python shell. also, the test.py file should be at the path you run from in the cli.

Windows 10 tested solution

• Type git bash in search

• Right click on it and choose open file location

• Right click on it and choose properties

• At target remove --cd-to-home from "C:\Program Files\Git\git-bash.exe" --cd-to-home

• At start in put the path of the directory you want it to start at for example Start in: C:\xampp\htdocs

No.

A developer is responsible for keeping track of time-zone information associated with a DateTime value via some external mechanism.

A quote from an excellent article here. A must read for every .Net developer.

So my advice is to write a little wrapper class that suits your needs.

The problem

You must NOT assume that an arbitrary input text file uses the "correct" platform-specific newline separator. This seems to be the source of your problem; it has little to do with regex.

To illustrate, on the Windows platform, System.getProperty("line.separator") is "\r\n" (CR+LF). However, when you run your Java code on this platform, you may very well have to deal with an input file whose line separator is simply "\n" (LF). Maybe this file was originally created in Unix platform, and then transferred in binary (instead of text) mode to Windows. There could be many scenarios where you may run into these kinds of situations, where you must parse a text file as input which does not use the current platform's newline separator.

(Coincidentally, when a Windows text file is transferred to Unix in binary mode, many editors would display ^M which confused some people who didn't understand what was going on).

When you are producing a text file as output, you should probably prefer the platform-specific newline separator, but when you are consuming a text file as input, it's probably not safe to make the assumption that it correctly uses the platform specific newline separator.

The solution

One way to solve the problem is to use e.g. java.util.Scanner. It has a nextLine() method that can return the next line (if one exists), correctly handling any inconsistency between the platform's newline separator and the input text file.

You can also combine 2 Scanner, one to scan the file line by line, and another to scan the tokens of each line. Here's a simple usage example that breaks each line into a List<String>. The entire file therefore becomes a List<List<String>>.

This is probably a better approach than reading the entire file into one huge String and then split into lines (which are then split into parts).

    String text
        = "row1\tblah\tblah\tblah\n"
        + "row2\t1\t2\t3\t4\r\n"
        + "row3\tA\tB\tC\r"
        + "row4";

    System.out.println(text);
    //  row1    blah    blah    blah
    //  row2    1   2   3   4
    //  row3    A   B   C
    //  row4

    List<List<String>> input = new ArrayList<List<String>>();

    Scanner sc = new Scanner(text);
    while (sc.hasNextLine()) {
        Scanner lineSc = new Scanner(sc.nextLine()).useDelimiter("\t");
        List<String> line = new ArrayList<String>();
        while (lineSc.hasNext()) {
            line.add(lineSc.next());
        }
        input.add(line);
    }
    System.out.println(input);
    // [[row1, blah, blah, blah], [row2, 1, 2, 3, 4], [row3, A, B, C], [row4]]

Props down, events up. That's Vue's Pattern. The point is that if you try to mutate props passing from a parent. It won't work and it just gets overwritten repeatedly by the parent component. Child component can only emit an event to notify parent component to do sth. If you don't like these restrict, you can use VUEX(actually this pattern will suck in complex components structure, you should use VUEX!)

You can also overload the increment/decrement operators for your enumerated type.

var id = $(this).find('option:selected').attr('id');

then you do whatever you want with selectedIndex

I've reedited my answer ... since selectedIndex isn't a good variable to give example...

ANSI SQL92:

• %
• _
• an ESCAPE character only if specified.

It is disappointing that many databases do not stick to the standard rules and add extra characters, or incorrectly enable ESCAPE with a default value of ‘\’ when it is missing. Like we don't already have enough trouble with ‘\’!

It's impossible to write DBMS-independent code here, because you don't know what characters you're going to have to escape, and the standard says you can't escape things that don't need to be escaped. (See section 8.5/General Rules/3.a.ii.)

Thank you SQL! gnnn

Static makes the clock member a class member instead of an instance member. Without the static keyword you would need to create an instance of the Hello class (which has a clock member variable) - e.g.

Hello hello = new Hello();
hello.clock.sayTime();

The main difference is that WHERE cannot be used on grouped item (such as SUM(number)) whereas HAVING can.

The reason is the WHERE is done before the grouping and HAVING is done after the grouping is done.

NULL is not a built-in constant in the C or C++ languages. In fact, in C++ it's more or less obsolete, just use a plain literal 0 instead, the compiler will do the right thing depending on the context.

In newer C++ (C++11 and higher), use nullptr (as pointed out in a comment, thanks).

Otherwise, add

#include <stddef.h>

to get the NULL definition.

Running a direct build APK will work. But make sure you uninstall any previously installed package of the same name.

Swift 3 & IBInspectable solution:

          get {
               if let borderColor = layer.borderColor {
                    return UIColor(cgColor: borderColor)
               }
               return nil
          }
     }
}

Then, simply select your UIView in interface builder setting shadow ON and corner radius, like below:

I'm currently taking some legacy codebases and introducing minimal TypeScript changes to see if it helps our team. Depending on how strict you want to be with TypeScript, this may or may not be an option for you.

The most helpful way for us to get started was to extend our tsconfig.json file with this property:

// tsconfig.json excerpt:

{
  ...
  "compilerOptions": {
    ...
    "allowJs": true,
    ...
  }
  ...
}

This change lets our JS files that have JSDoc type hints get compiled. Also our IDEs (JetBrains IDEs and VS Code) can provide code-completion and Intellisense.

Try creating a linked server (which you can do with sp_addlinkedserver) and then using OPENQUERY

@PathVariable is used to tell Spring that part of the URI path is a value you want passed to your method. Is this what you want, or are the variables supposed to be form data posted to the URI?

If you want form data, use @RequestParam instead of @PathVariable.

If you want @PathVariable, you need to specify placeholders in the @RequestMapping entry to tell Spring where the path variables fit in the URI. For example, if you want to extract a path variable called contentId, you would use:

@RequestMapping(value = "/whatever/{contentId}", method = RequestMethod.POST)

Edit: Additionally, if your path variable could contain a '.' and you want that part of the data, then you will need to tell Spring to grab everything, not just the stuff before the '.':

@RequestMapping(value = "/whatever/{contentId:.*}", method = RequestMethod.POST)

This is because the default behaviour of Spring is to treat that part of the URL as if it is a file extension, and excludes it from variable extraction.

If session.cookie_lifetime is 0, the session cookie lives until the browser is quit.

EDIT: Others have mentioned the session.gc_maxlifetime setting. When session garbage collection occurs, the garbage collector will delete any session data that has not been accessed in longer than session.gc_maxlifetime seconds. To set the time-to-live for the session cookie, call session_set_cookie_params() or define the session.cookie_lifetime PHP setting. If this setting is greater than session.gc_maxlifetime, you should increase session.gc_maxlifetime to a value greater than or equal to the cookie lifetime to ensure that your sessions won't expire.

For Google Chrome (Tested on ver. 62)

I was trying to keep a socket connection alive from the google chrome's fetch API to a remote express server and found the request headers have to match Node.JS's native <net.socket> connection settings.

I set the headers object on my client-side script with the following options:

/* ----- */
head = new headers();
head.append("Connnection", "keep-alive")
head.append("Keep-Alive", `timeout=${1*60*5}`) //in seconds, not milliseconds
/* apply more definitions to the header */
fetch(url, {
    method: 'OPTIONS',
    credentials: "include",
    body: JSON.stringify(data),
    cors: 'cors',
    headers: head, //could be object literal too
    cache: 'default'
 })
 .then(response=>{
    ....
  }).catch(err=>{...});

And on my express server I setup my router as follows:

 router.head('absolute or regex', (request, response, next)=>{
  req.setTimeout(1000*60*5, ()=>{
     console.info("socket timed out");
   });
  console.info("Proceeding down the middleware chain link...\n\n");
  next();
 });

 /*Keep the socket alive by enabling it on the server, with an optional 
  delay on the last packet sent 
 */
server.on('connection', (socket)=>socket.setKeepAlive(true, 10))

WARNING

Please use common sense and make sure the users you're keeping the socket connection open to is validated and serialized. It works for Firefox as well, but it's really vulnerable if you keep the TCP connection open for longer than 5 minutes.

I'm not sure how some of the lesser known browsers operate, but I'll append to this answer with the Microsoft browser details as well.

We can have two ways of calling the functions written in pgadmin for postgre sql database.

Suppose we have defined the function as below:

CREATE OR REPLACE FUNCTION helloWorld(name text) RETURNS void AS $helloWorld$
DECLARE
BEGIN
    RAISE LOG 'Hello, %', name;
END;
$helloWorld$ LANGUAGE plpgsql;

We can call the function helloworld in one of the following way:

SELECT "helloworld"('myname');

SELECT public.helloworld('myname')

The 'best' way to do this would be to set a property on a view object once the update is successful. You can then access this property in the view and inform the user accordingly.

Having said that it would be possible to trigger an alert from the controller code by doing something like this -

public ActionResult ActionName(PostBackData postbackdata)
{
    //your DB code
    return new JavascriptResult { Script = "alert('Successfully registered');" };
}

You can find further info in this question - How to display "Message box" using MVC3 controller

It could also be because you're trying to put in a null value back into the database. So one of your transactions could have nulls in them.

By default all class methods are public. To make them private you can use Module#private_class_method like @tjwallace wrote or define them differently, as you did:

class << self

  private

  def method_name
    ...
  end
end

class << self opens up self's singleton class, so that methods can be redefined for the current self object. This is used to define class/module ("static") method. Only there, defining private methods really gives you private class methods.

EDIT - Removed Skip(0) as it's not necessary

var queryResult = (from o in objects where ...
                      select new
                      {
                          A = o.a,
                          B = o.b
                      }
                  ).Take(10);

Renaming .bashrc to .profile (or soft-linking the latter to the former) should also do the trick. See here.

cd ~/My\ Code

seems to work for me... If dropping the quotes but keeping the slash doesn't work, can you post some sample code?

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

I am on XCode 10 with RN version 0.5.7, I tried almost all solutions and nothing worked.

After loosing a lot of time, finally the way I got it to working by doing the following

1. Install previous version of react-native by running react-native init project --version [email protected]
2. Open project/ios/project.xcodeproj and select Debug for command line builds
3. Make sure to select the correct development certificate
4. Run react-native run-ios once again, this time it must work.

Since the onItemClickLitener() will itself provide you the index of the selected item, you can simply do a getItemAtPosition(i).toString(). The code snippet is given below :-

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            String s = listView.getItemAtPosition(i).toString();

            Toast.makeText(activity.getApplicationContext(), s, Toast.LENGTH_LONG).show();
            adapter.dismiss(); // If you want to close the adapter
        }
    });

On the method above, the i parameter actually gives you the position of the selected item.

You need to use the border property as seen here: jsFiddle

HTML:

<table width="770">
    <tr>
        <td class="border-left-bottom">picture (border only to the left and bottom ) </td>
        <td>text</td>
    </tr>
    <tr>
        <td>text</td>
        <td class="border-left-bottom">picture (border only to the left and bottom) </td>
    </tr>
</table>`

CSS:

td.border-left-bottom{
    border-left: solid 1px #000;
    border-bottom: solid 1px #000;
}

<% response.write("<script language=""javascript"">alert('Hello!');</script>") %>

Using rcParams you can show grid very easily as follows

plt.rcParams['axes.facecolor'] = 'white'
plt.rcParams['axes.edgecolor'] = 'white'
plt.rcParams['axes.grid'] = True
plt.rcParams['grid.alpha'] = 1
plt.rcParams['grid.color'] = "#cccccc"

If grid is not showing even after changing these parameters then use

plt.grid(True)

before calling

plt.show()

with bootstrap use class input-md = medium, input-lg = large, for more info see https://getbootstrap.com/docs/3.3/css/#forms-control-sizes

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Casting to an int truncates the value. Adding 0.5 causes it to do proper rounding.

int y = (int)(x + 0.5);

I had same problem and beside some values inside my table. Although I changed my Primary Key with

ALTER TABLEuser_customer_permissionDROP PRIMARY KEY , ADD PRIMARY KEY (id)

problem continued on my server. I created new field inside the table I transfered the values into new field and deleted old one, problem solved!!

The full modern solution to your problem is purely CSS-based, but note that older browsers won't support it, in which cases you'd need to fallback to solutions such as the others have provided.

So in pure CSS:

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;

However the mouse cursor will still change to a caret when over the element's text, so you add to that:

cursor: default;

Modern CSS is pretty elegant.

Try this

Sub Sample()
    Dim test As Worksheet
    Sheets(1).Copy After:=Sheets(Sheets.Count)
    Set test = ActiveSheet
    test.Name = "copied sheet!"
End Sub

Be careful on:

 Header add Access-Control-Allow-Origin "*"

This is not judicious at all to grant access to everybody. It's preferable to allow a list of know trusted host only...

Header add Access-Control-Allow-Origin "http://aaa.example"
Header add Access-Control-Allow-Origin "http://bbb.example"
Header add Access-Control-Allow-Origin "http://ccc.example"

Thank you all for this thread! My colleague and I just discovered that the default_value property is a Constant, not a Variable.

In other React forms I've built, the default value for a Select was preset in an associated Context. So the first time the Select was rendered, default_value was set to the correct value.

But in my latest React form (a small modal), I'm passing the values for the form as props and then using a useEffect to populate the associated Context. So the FIRST time the Select is rendered, default_value is set to null. Then when the Context is populated and the Select is supposed to be re-rendered, default_value cannot be changed and thus the initial default value is not set.

The solution was ultimately simple: Use the value property instead. But figuring out why default_value didn't work like it did with my other forms took some time.

I'm posting this to help others in the community.

This referes to http://blogs.msdn.com/b/pfxteam/archive/2012/02/12/10266988.aspx , http://winrtstoragehelper.codeplex.com/ , Windows 8 app store and .net 4.5

Here is my angle on this:

The async/await language feature makes many things fairly easy but it also introduces a scenario that was rarely encounter before it was so easy to use async calls: reentrance.

This is especially true for event handlers, because for many events you don't have any clue about whats happening after you return from the event handler. One thing that might actually happen is, that the async method you are awaiting in the first event handler, gets called from another event handler still on the same thread.

Here is a real scenario I came across in a windows 8 App store app: My app has two frames: coming into and leaving from a frame I want to load/safe some data to file/storage. OnNavigatedTo/From events are used for the saving and loading. The saving and loading is done by some async utility function (like http://winrtstoragehelper.codeplex.com/). When navigating from frame 1 to frame 2 or in the other direction, the async load and safe operations are called and awaited. The event handlers become async returning void => they cant be awaited.

However, the first file open operation (lets says: inside a save function) of the utility is async too and so the first await returns control to the framework, which sometime later calls the other utility (load) via the second event handler. The load now tries to open the same file and if the file is open by now for the save operation, fails with an ACCESSDENIED exception.

A minimum solution for me is to secure the file access via a using and an AsyncLock.

private static readonly AsyncLock m_lock = new AsyncLock();
...

using (await m_lock.LockAsync())
{
    file = await folder.GetFileAsync(fileName);
    IRandomAccessStream readStream = await file.OpenAsync(FileAccessMode.Read);
    using (Stream inStream = Task.Run(() => readStream.AsStreamForRead()).Result)
    {
        return (T)serializer.Deserialize(inStream);
    }
}

Please note that his lock basically locks down all file operation for the utility with just one lock, which is unnecessarily strong but works fine for my scenario.

Here is my test project: a windows 8 app store app with some test calls for the original version from http://winrtstoragehelper.codeplex.com/ and my modified version that uses the AsyncLock from Stephen Toub http://blogs.msdn.com/b/pfxteam/archive/2012/02/12/10266988.aspx.

May I also suggest this link: http://www.hanselman.com/blog/ComparingTwoTechniquesInNETAsynchronousCoordinationPrimitives.aspx

The first argument after the "run" that is not a flag or parameter to a flag is parsed as an image name. When that parsing fails, it tells you the reference format, aka image name (but could be an image id, pinned image, or other syntax) is invalid. In your command:

 docker run -p 8888:8888 -v `pwd`/../src:/src -v `pwd`/../data:/data -w /src supervisely_anpr --rm -it bash

The image name "supervisely_anpr" is valid, so you need to look earlier in the command. In this case, the error is most likely from pwd outputting a path with a space in it. Everything after the space is no longer a parameter to -v and docker tries to parse it as the image name. The fix is to quote the volume parameters when you cannot guarantee it is free of spaces or other special characters.

When you do that, you'll encounter the next error, "executable not found". Everything after the image name is parsed as the command to run inside the container. In your case, it will try to run the command --rm -it bash which will almost certainly fail since --rm will no exist as a binary inside your image. You need to reorder the parameters to resolve that:

 docker run --rm -it -p 8888:8888 -v "`pwd`/../src:/src" -v "`pwd`/../data:/data" -w /src supervisely_anpr  bash

I've got some more details on these two errors and causes in my slides here: https://sudo-bmitch.github.io/presentations/dc2018/faq-stackoverflow-lightning.html#29

This error means you can not directly load data from file system because there are security issues behind this. The only solution that I know is create a web service to serve load files.

@mikepenz has the right one.

You could just hit SHIFT+COMMAND+A (if you're using OSX and 1.4 android studio) and enter OFFLINE in the search box.

Then you'll see what mike have shown you.

oops! just found myself: just add this line on any element you need

   -webkit-appearance: none;

Scenario: I have a navigation menu like this. Note: Link <a> is child of list item <li>. I wanted to change the background of the selected list item and remove the background color of unselected list item.

<nav>
        <ul>
            <li><a href="#">Intro</a></li>
            <li><a href="#">Size</a></li>
            <li><a href="#">Play</a></li>
            <li><a href="#">Food</a></li>
        </ul>
        <div class="clear"></div>

       </nav>

I tried to add a class .active into the list item using jQuery but it was not working

.active
{
    background-color: #480048;
}

$("nav li a").click(function () {
        $(this).parent().addClass("active");
        $(this).parent().siblings().removeClass("active");
    });

Solution: Basically, using .active class changing the background-color of list item does not work. So I changed the css class name from .active to "nav li.active a" so using the same javascript it will add the .active class into the selected list item. Now if the list item <li> has .active class then css will change the background color of the child of that list item <a>.

nav li.active a
{
    background-color: #480048;
}

I'm lately here. But somethings I just known that might help you a bit.

If you are using Java, there is nothing much to change. But for kotlin developers, here is some following snippet I think that can make you a basement to run on:

• Parent fragment:

inline fun <reified T : SampleFragment> newInstance(text: String): T {
    return T::class.java.newInstance().apply {
        arguments = Bundle().also { it.putString("key_text_arg", text) }
    }
}

• Normal call

val f: SampleFragment = SampleFragment.newInstance("ABC")
// or val f = SampleFragment.newInstance<SampleFragment>("ABC")

• You can extend the parent init operation in child fragment class by:

fun newInstance(): ChildSampleFragment {
    val child = UserProfileFragment.newInstance<ChildSampleFragment>("XYZ")
    // Do anything with the current initialized args bundle here
    // with child.arguments = ....
    return child
}

Happy coding.

Although Objective-C does indeed appear to be "insane" initially, I encourage you to stick with it. Once you have an "a-ha" moment, suddenly it all starts to make sense. For me it took about 2 weeks of focused Objective-C concentration to really understand the Cocoa frameworks, the language, and how it all fits together. But once I really "got" it, it was very very exciting.

It sounds cliché, but it's true. Stick it out.

Of course, if you're bringing in C++ libraries or existing C++ code, you can use those modules with Objective-C/Objective-C++.

Modern CSS Grid Answer

View the fully working code on CodePen. Given the following HTML:

<div class="container">
    <p>Several paragraphs of text...</p>
</div>

You can use CSS Grid to create three columns and tell the container to take a maximum width of 70 characters for the middle column which contains our paragraph.

.container
{
  display: grid;
  grid-template-columns: 1fr, 70ch 1fr;
}

p {
  grid-column: 2 / 3;
}

This is what it looks like (Checkout CodePen for a fully working example):

Here is another example where you can use minmax to set a range of values. On small screens the width will be set to 50 characters wide and on large screens it will be 70 characters wide.

.container
{
  display: grid;
  grid-template-columns: 1fr minmax(50ch, 70ch) 1fr;
}

p {
  grid-column: 2 / 3;
}

Meanwhile, another reason : accidentally deleted the .config file caused the same error message appears:

"Service on local computer started and then stopped. some services stop automatically..."

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
