POSTMAN : A google chrome extension

Use postman to send message instead of server. Postman settings are as follows :

Request Type: POST

URL: https://android.googleapis.com/gcm/send

Header
  Authorization  : key=your key //Google API KEY
  Content-Type : application/json

JSON (raw) :
{       
  "registration_ids":["yours"],
  "data": {
    "Hello" : "World"
  } 
}

on success you will get

Response :
{
  "multicast_id": 6506103988515583000,
  "success": 1,
  "failure": 0,
  "canonical_ids": 0,
  "results": [
    {
      "message_id": "0:1432811719975865%54f79db3f9fd7ecd"
    }
  ]
}

Based on the Microsoft support KBs, this can occur if TCP/IP is damaged or is not bound to your dial-up adapter.You can try reinstalling or resetting TCP/IP as follows:

• Reset TCP/IP to Original Configuration- Using the NetShell utility, type this command (in CommandLine): netsh int ip reset [file_name.txt], [file_name.txt] is the name of the file where the actions taken by NetShell are record, for example netsh hint ip reset fixtcpip.txt.

• Remove and re-install NIC – Open Controller and select System. Click Hardware tab and select devices. Double-click on Network Adapter and right-click on the NIC, select Uninstall. Restart the computer and the Windows should auto detect the NIC and re-install it.

• Upgrade the NIC driver – You may download the latest NIC driver and upgrade the driver.

Hope it could help.

my_bytes_value = b'[{\'Date\': \'2016-05-21T21:35:40Z\', \'CreationDate\': \'2012-05-05\', \'LogoType\': \'png\', \'Ref\': 164611595, \'Classe\': [\'Email addresses\', \'Passwords\'],\'Link\':\'http://some_link.com\'}]'

fix_bytes_value = my_bytes_value.replace(b"'", b'"')

my_json = json.load(io.BytesIO(fix_bytes_value))  

It depends on the semantic of the primary key. If it's just autoincrement, then use something like:

insert into table1 (all columns except pk)
select all_columns_except_pk 
from table2;

If PK means something, you need to find a way to determine which record should have priority. You could create a select query to find duplicates first (see answer by cpitis). Then eliminate the ones you don't want to keep and use the above insert to add records that remain.

Both will works perfectly in mysqli_fetch_array in while loops

while($row = mysqli_fetch_array($result,MYSQLI_BOTH)) {
    $posts[] = $row['post_id'].$row['post_title'].$row['content'];
}

(OR)

while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) {
    $posts[] = $row['post_id'].$row['post_title'].$row['content'];
}

mysqli_fetch_array() - has second argument $resulttype.

MYSQLI_ASSOC: Fetch associative array

MYSQLI_NUM: Fetch numeric array

MYSQLI_BOTH: Fetch both associative and numeric array.

In order to print the Country and Place with maximum value, use the following line of code.

In a few words: The constructor is called first, then any @FXML annotated fields are populated, then initialize() is called.

This means the constructor does not have access to @FXML fields referring to components defined in the .fxml file, while initialize() does have access to them.

Quoting from the Introduction to FXML:

[...] the controller can define an initialize() method, which will be called once on an implementing controller when the contents of its associated document have been completely loaded [...] This allows the implementing class to perform any necessary post-processing on the content.

I want columns One and Two to shrink/grow to fit rather than being fixed.

Have you tried: flex-basis: auto

or this:

flex: 1 1 auto, which is short for:

• flex-grow: 1 (grow proportionally)
• flex-shrink: 1 (shrink proportionally)
• flex-basis: auto (initial size based on content size)

or this:

main > section:first-child {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:nth-child(2) {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:last-child {
    flex: 20 1 auto;
    display: flex;
    flex-direction: column;  
}

A big thank you to @Musa and here is a neat function that converts the data to a base64 string. This may come handy to you when handling a binary file (pdf, png, jpeg, docx, ...) file in a WebView that gets the binary file but you need to transfer the file's data safely into your app.

// runs a get/post on url with post variables, where:
// url ... your url
// post ... {'key1':'value1', 'key2':'value2', ...}
//          set to null if you need a GET instead of POST req
// done ... function(t) called when request returns
function getFile(url, post, done)
{
   var postEnc, method;
   if (post == null)
   {
      postEnc = '';
      method = 'GET';
   }
   else
   {
      method = 'POST';
      postEnc = new FormData();
      for(var i in post)
         postEnc.append(i, post[i]);
   }
   var xhr = new XMLHttpRequest();
   xhr.onreadystatechange = function() {
      if (this.readyState == 4 && this.status == 200)
      {
         var res = this.response;
         var reader = new window.FileReader();
         reader.readAsDataURL(res); 
         reader.onloadend = function() { done(reader.result.split('base64,')[1]); }
      }
   }
   xhr.open(method, url);
   xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
   xhr.send('fname=Henry&lname=Ford');
   xhr.responseType = 'blob';
   xhr.send(postEnc);
}

I followed the link shared by lisachenko and found another link to this blog: http://guilhembichot.blogspot.co.uk/2013/11/with-recursive-and-mysql.html

The post lays out ways of emulating the 2 uses of SQL WITH. Really good explanation on how these work to do a similar query as SQL WITH.

1) Use WITH so you don't have to perform the same sub query multiple times

CREATE VIEW D AS (SELECT YEAR, SUM(SALES) AS S FROM T1 GROUP BY YEAR);
SELECT D1.YEAR, (CASE WHEN D1.S>D2.S THEN 'INCREASE' ELSE 'DECREASE' END) AS TREND
FROM
 D AS D1,
 D AS D2
WHERE D1.YEAR = D2.YEAR-1;
DROP VIEW D;

2) Recursive queries can be done with a stored procedure that makes the call similar to a recursive with query.

CALL WITH_EMULATOR(
"EMPLOYEES_EXTENDED",
"
  SELECT ID, NAME, MANAGER_ID, 0 AS REPORTS
  FROM EMPLOYEES
  WHERE ID NOT IN (SELECT MANAGER_ID FROM EMPLOYEES WHERE MANAGER_ID IS NOT NULL)
",
"
  SELECT M.ID, M.NAME, M.MANAGER_ID, SUM(1+E.REPORTS) AS REPORTS
  FROM EMPLOYEES M JOIN EMPLOYEES_EXTENDED E ON M.ID=E.MANAGER_ID
  GROUP BY M.ID, M.NAME, M.MANAGER_ID
",
"SELECT * FROM EMPLOYEES_EXTENDED",
0,
""
);

And this is the code or the stored procedure

# Usage: the standard syntax:
#   WITH RECURSIVE recursive_table AS
#    (initial_SELECT
#     UNION ALL
#     recursive_SELECT)
#   final_SELECT;
# should be translated by you to 
# CALL WITH_EMULATOR(recursive_table, initial_SELECT, recursive_SELECT,
#                    final_SELECT, 0, "").

# ALGORITHM:
# 1) we have an initial table T0 (actual name is an argument
# "recursive_table"), we fill it with result of initial_SELECT.
# 2) We have a union table U, initially empty.
# 3) Loop:
#   add rows of T0 to U,
#   run recursive_SELECT based on T0 and put result into table T1,
#   if T1 is empty
#      then leave loop,
#      else swap T0 and T1 (renaming) and empty T1
# 4) Drop T0, T1
# 5) Rename U to T0
# 6) run final select, send relult to client

# This is for *one* recursive table.
# It would be possible to write a SP creating multiple recursive tables.

slaveOk does not work anymore. One needs to use readPreference https://docs.mongodb.com/v3.0/reference/read-preference/#primaryPreferred

e.g.

const client = new MongoClient(mongoURL + "?readPreference=primaryPreferred", { useUnifiedTopology: true, useNewUrlParser: true });

This works with multiple statements:

if condition1 Then stmt1:stmt2 Else if condition2 Then stmt3:stmt4 Else stmt5:stmt6

Or you can split it over multiple lines:

if condition1 Then stmt1:stmt2
Else if condition2 Then stmt3:stmt4
Else stmt5:stmt6

Are you sure your HTML form is correct, and does, in fact, do an HTTP POST? I would suggest running Fiddler2, and then trying to log in via your Login.aspx, then the remote HTML site, and then comparing the requests that are sent to the server. For me, ASP.Net always worked fine -- if HTTP request contains a valid POST, I can get to values using Request.Form...

As the error message states, jQuery does not include a :unchecked selector.
Instead, you need to invert the :checked selector:

$("input:checkbox:not(:checked)")

Important update (Python 3.4):

Any identifier of the form __name (at least two leading underscores, at most one trailing underscore) is publicly replaced with _classname__name, where classname is the current class name with leading underscore(s) stripped.

Therefore, __name is private, while _classname__name is public.

https://docs.python.org/3/tutorial/classes.html#tut-private

Example

class Cat:
    def __init__(self, name='unnamed'):
        self.name = name
    def __print_my_name(self):
        print(self.name)
        
        
tom = Cat()
tom.__print_my_name() #Error
tom._Cat__print_my_name() #Prints name

It's extremely unlikely that an if/else or a switch is going to be the source of your performance woes. If you're having performance problems, you should do a performance profiling analysis first to determine where the slow spots are. Premature optimization is the root of all evil!

Nevertheless, it's possible to talk about the relative performance of switch vs. if/else with the Java compiler optimizations. First note that in Java, switch statements operate on a very limited domain -- integers. In general, you can view a switch statement as follows:

switch (<condition>) {
   case c_0: ...
   case c_1: ...
   ...
   case c_n: ...
   default: ...
}

where c_0, c_1, ..., and c_N are integral numbers that are targets of the switch statement, and <condition> must resolve to an integer expression.

• If this set is "dense" -- that is, (max(c_i) + 1 - min(c_i)) / n > α, where 0 < k < α < 1, where k is larger than some empirical value, a jump table can be generated, which is highly efficient.

• If this set is not very dense, but n >= β, a binary search tree can find the target in O(2 * log(n)) which is still efficient too.

For all other cases, a switch statement is exactly as efficient as the equivalent series of if/else statements. The precise values of α and β depend on a number of factors and are determined by the compiler's code-optimization module.

Finally, of course, if the domain of <condition> is not the integers, a switch statement is completely useless.

I'm using Android Studio 0.8.6 and I couldn't find:

android:background="@drawable/abc_menu_dropdown_panel_holo_light"

so I found this instead:

android:background="@android:drawable/dialog_holo_light_frame"

and it looks like this:

The other way to move introduced work from one branch to another is to cherry-pick it. A cherry-pick in Git is like a rebase for a single commit. It takes the patch that was introduced in a commit and tries to reapply it on the branch you’re currently on. This is useful if you have a number of commits on a topic branch and you want to integrate only one of them, or if you only have one commit on a topic branch and you’d prefer to cherry-pick it rather than run rebase. For example, suppose you have a project that looks like this:

If you want to pull commit e43a6 into your master branch, you can run

$ git cherry-pick e43a6
Finished one cherry-pick.
[master]: created a0a41a9: "More friendly message when locking the index fails."
 3 files changed, 17 insertions(+), 3 deletions(-)

This pulls the same change introduced in e43a6, but you get a new commit SHA-1 value, because the date applied is different. Now your history looks like this:

Now you can remove your topic branch and drop the commits you didn’t want to pull in.

An inner class cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?".

as u said here inner class cannot be static... i found the below code which is being given static....reason? or which is correct....

Yes, there is nothing in the semantics of a static nested type that would stop you from doing that. This snippet runs fine.

    public class MultipleInner {
        static class Inner {
        }   
    public static void main(String[] args) {
        for (int i = 0; i < 100; i++) {
            new Inner();
        }
    }
}

this is a code posted in this website...

for the question---> Can a Static Nested Class be Instantiated Multiple Times?

answer was--->

Now, of course the nested type can do its own instance control (e.g. private constructors, singleton pattern, etc) but that has nothing to do with the fact that it's a nested type. Also, if the nested type is a static enum, of course you can't instantiate it at all.

But in general, yes, a static nested type can be instantiated multiple times.

Note that technically, a static nested type is not an "inner" type.

Be sure to check out the VS 2010 Beta that was just released. The new editor should have this.

I solved this issue by increasing my server ram.

I was running only 512 MB and when I upgraded to 1 GB I had no problem.

I also installed every package manually prior to this in an attempt to fix the problem, but I'm not sure whether this is a necessary step.

Last column in your input file must have some data in it (be it space or char, but not null). I guess, 1st record contains null after last ',' which sqlldr won't recognize unless specifically asked to recognize nulls using TRAILING NULLCOLS option. Alternatively, if you don't want to use TRAILING NULLCOLS, you will have to take care of those NULLs before you pass the file to sqlldr. Hope this helps

For Linux

Open Terminal :

For Debug Build

keytool -exportcert -alias androiddebugkey -keystore debug.keystore | openssl sha1 -binary | openssl base64

you wil find debug.keystore from ".android" folder copy it from and paste on desktop and run above command

For release Build

keytool -exportcert -alias <aliasName> -keystore <keystoreFilePath> | openssl sha1 -binary | openssl base64

NOTE : Make sure In Both case it must ask for password. If it does not asks for password that means something is wrong in command.

You're almost there. Use the following regex (with multi-line option enabled)

\bObject Name:\s+(.*)$

The complete match would be

Object Name:   D:\ApacheTomcat\apache-tomcat-6.0.36\logs\localhost.2013-07-01.log

while the captured group one would contain

D:\ApacheTomcat\apache-tomcat-6.0.36\logs\localhost.2013-07-01.log

If you want to capture the file path directly use

(?m)(?<=\bObject Name:).*$

You can't instantiate interfaces or abstract classes.

That's because it wouldn't have any logic to it.

Interfaces provide a contract of the methods that should be in a class, without implementation. (So there's no actual logic in the interface).

Abstract classes provide basic logic of a class, but are not fully functional (not everything is implemented). So again, you won't be able to do anything with it.

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

The original answers to the question are good, but newer versions of mysql (MySQL 5.7.6 on) support geo queries, so you can now use built in functionality rather than doing complex queries.

You can now do something like:

select *, ST_Distance_Sphere( point ('input_longitude', 'input_latitude'), 
                              point(longitude, latitude)) * .000621371192 
          as `distance_in_miles` 
  from `TableName`
having `distance_in_miles` <= 'input_max_distance'
 order by `distance_in_miles` asc

The results are returned in meters. So if you want in KM simply use .001 instead of .000621371192 (which is for miles).

MySql docs are here

In my case, restarting apache fixed the problem. for Ubuntu / Debian:

sudo service apache2 restart

To install a Python package you've downloaded, you extract the archive and run the setup.py script inside:

python setup.py install

To me, this has always felt odd. It would be more natural to point a package manager at the download, as one would do in Ruby and Nodejs, eg. gem install rails-4.1.1.gem

A package manager is more comfortable too, because it's familiar and reliable. On the other hand, each setup.py is novel, because it's specific to the package. It demands faith in convention "I trust this setup.py takes the same commands as others I have used in the past". That's a regrettable tax on mental willpower.

I'm not saying the setup.py workflow is less secure than a package manager (I understand Pip just runs the setup.py inside), but certainly I feel it's awkard and jarring. There's a harmony to commands all being to the same package manager application. You might even grow fond it.

Use the split function.

static void Main(string[] args)
{
    string s = "223232-1.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "443-2.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "34443553-5.jpg";
    Console.WriteLine(s.Split('-')[0]);

Console.ReadKey();
}

If your string doesn't have a - then you'll get the whole string.

For integers with values of 0 and 1 you can try:

value = abs(value - 1);

MWE in C:

#include <stdio.h>
#include <stdlib.h>
int main()
{
        printf("Hello, World!\n");
        int value = 0;
        int i;
        for (i=0; i<10; i++)
        {
                value = abs(value -1);
                printf("%d\n", value);
        }
        return 0;
}

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.

<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
  This worked perfectly fine.
</xsl:if>

The directory should be named 'dump' and this directory should have a directory which contains the .bson and .json files. This directory should be named as your db name.

eg: if your db name is institution then the second directory name should be institution.

After this step, go the directory enclosing the dump folder in the terminal, and run the command

mongorestore --drop.

Do see to it that mongo is up and running.

This should work fine.

Just call dismiss() from the fragment you want to dismiss.

All of the following applies to InnoDB.

I feel knowing the speeds of the 3 different methods is important.

There are 3 methods:

1. INSERT: INSERT with ON DUPLICATE KEY UPDATE
2. TRANSACTION: Where you do an update for each record within a transaction
3. CASE: In which you a case/when for each different record within an UPDATE

I just tested this, and the INSERT method was 6.7x faster for me than the TRANSACTION method. I tried on a set of both 3,000 and 30,000 rows.

The TRANSACTION method still has to run each individually query, which takes time, though it batches the results in memory, or something, while executing. The TRANSACTION method is also pretty expensive in both replication and query logs.

Even worse, the CASE method was 41.1x slower than the INSERT method w/ 30,000 records (6.1x slower than TRANSACTION). And 75x slower in MyISAM. INSERT and CASE methods broke even at ~1,000 records. Even at 100 records, the CASE method is BARELY faster.

So in general, I feel the INSERT method is both best and easiest to use. The queries are smaller and easier to read and only take up 1 query of action. This applies to both InnoDB and MyISAM.

Bonus stuff:

The solution for the INSERT non-default-field problem is to temporarily turn off the relevant SQL modes: SET SESSION sql_mode=REPLACE(REPLACE(@@SESSION.sql_mode,"STRICT_TRANS_TABLES",""),"STRICT_ALL_TABLES",""). Make sure to save the sql_mode first if you plan on reverting it.

As for other comments I've seen that say the auto_increment goes up using the INSERT method, this does seem to be the case in InnoDB, but not MyISAM.

Code to run the tests is as follows. It also outputs .SQL files to remove php interpreter overhead

<?php
//Variables
$NumRows=30000;

//These 2 functions need to be filled in
function InitSQL()
{

}
function RunSQLQuery($Q)
{

}

//Run the 3 tests
InitSQL();
for($i=0;$i<3;$i++)
    RunTest($i, $NumRows);

function RunTest($TestNum, $NumRows)
{
    $TheQueries=Array();
    $DoQuery=function($Query) use (&$TheQueries)
    {
        RunSQLQuery($Query);
        $TheQueries[]=$Query;
    };

    $TableName='Test';
    $DoQuery('DROP TABLE IF EXISTS '.$TableName);
    $DoQuery('CREATE TABLE '.$TableName.' (i1 int NOT NULL AUTO_INCREMENT, i2 int NOT NULL, primary key (i1)) ENGINE=InnoDB');
    $DoQuery('INSERT INTO '.$TableName.' (i2) VALUES ('.implode('), (', range(2, $NumRows+1)).')');

    if($TestNum==0)
    {
        $TestName='Transaction';
        $Start=microtime(true);
        $DoQuery('START TRANSACTION');
        for($i=1;$i<=$NumRows;$i++)
            $DoQuery('UPDATE '.$TableName.' SET i2='.(($i+5)*1000).' WHERE i1='.$i);
        $DoQuery('COMMIT');
    }
    
    if($TestNum==1)
    {
        $TestName='Insert';
        $Query=Array();
        for($i=1;$i<=$NumRows;$i++)
            $Query[]=sprintf("(%d,%d)", $i, (($i+5)*1000));
        $Start=microtime(true);
        $DoQuery('INSERT INTO '.$TableName.' VALUES '.implode(', ', $Query).' ON DUPLICATE KEY UPDATE i2=VALUES(i2)');
    }
    
    if($TestNum==2)
    {
        $TestName='Case';
        $Query=Array();
        for($i=1;$i<=$NumRows;$i++)

        $Start=microtime(true);
        $DoQuery("UPDATE $TableName SET i2=CASE i1\n".implode("\n", $Query)."\nEND\nWHERE i1 IN (".implode(',', range(1, $NumRows)).')');
    }
    
    print "$TestName: ".(microtime(true)-$Start)."<br>\n";

    file_put_contents("./$TestName.sql", implode(";\n", $TheQueries).';');
}

You can do it this way:

object a = new StreamWriter("c:\\temp\\test.txt");

if (a is TextReader == false)
{
   Console.WriteLine("failed");
}

Very C/C++ style solution:

    foo = 5
    objectsList = [3, 6, 5, 9, 10]
    prev = nex = 0
    
    currentIndex = 0
    indexHigher = len(objectsList)-1 #control the higher limit of list
    
    found = False
    prevFound = False
    nexFound = False
    
    #main logic:
    for currentValue in objectsList: #getting each value of list
        if currentValue == foo:
            found = True
            if currentIndex > 0: #check if target value is in the first position   
                prevFound = True
                prev = objectsList[currentIndex-1]
            if currentIndex < indexHigher: #check if target value is in the last position
                nexFound = True
                nex = objectsList[currentIndex+1]
            break #I am considering that target value only exist 1 time in the list
        currentIndex+=1
    
    if found:
        print("Value %s found" % foo)
        if prevFound:
            print("Previous Value: ", prev)
        else:
            print("Previous Value: Target value is in the first position of list.")
        if nexFound:
            print("Next Value: ", nex)
        else:
            print("Next Value: Target value is in the last position of list.")
    else:
        print("Target value does not exist in the list.")

Have you googled about it - insert update delete access vb.net, there are lots of reference about this.

Insert Update Delete Navigation & Searching In Access Database Using VB.NET

• Create Visual Basic 2010 Project: VB-Access
• Assume that, we have a database file named data.mdb
• Place the data.mdb file into ..\bin\Debug\ folder (Where the project executable file (.exe) is placed)

what could be the easier way to connect and manipulate the DB?
Use OleDBConnection class to make connection with DB

is it by using MS ACCESS 2003 or MS ACCESS 2007?
you can use any you want to use or your client will use on their machine.

it seems that you want to find some example of opereations fo the database. Here is an example of Access 2010 for your reference:

To get the directory, you can use the code below:

File cacheDir = new File(Environment.getExternalStorageDirectory() + File.separator + "");

Here is an update to the solution provided by @user235218 that allows you to specify number of milliseconds you require.

Note: The -n option is the number of retries and the -w is the timeout in milliseconds for ping. I chose the 127.255.255.254 address because it is in the loopback range and ms windows doesn’t respond to it.

I also doubt this will provide millisecond accuracy but on another note i tried it in an application using the ms script control and whilst the built in sleep function locked up the interface this method didn't.

If somebody can provide an explanation for why this method didn't lock up the interface we could make this answer more complete. Both sleep functions where run in the user thread.

Const WshHide = 0
Const WAIT_ON_RETURN = True

Sub Sleep(ByVal ms)

   Dim shell 'As WScript.Shell

   If Not IsNumeric(ms) Then _
       Exit Sub

   Set shell = CreateObject("WScript.Shell")

   Call shell.Run("%COMSPEC% /c ping -n 1 -w " & ms & " 127.255.255.254 > nul", WshHide, WAIT_ON_RETURN)

End Sub

I tried using the dtypes=[datetime, ...] option, but

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

I encountered the following error:

TypeError: data type not understood

The only change I had to make is to replace datetime with datetime.datetime

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime.datetime, datetime.datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

I have just finished adding Google Maps to my company's CMS offering. My code allows for more than one map in a page.

Notes:

• I use jQuery
• I put the address in the content and then parse it out to dynamically generate the map
• I include a Marker and an InfoWindow in my map

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.

From the latest working spec for window.close():

The close() method on Window objects should, if all the following conditions are met, close the browsing context A:

• The corresponding browsing context A is script-closable.
• The browsing context of the incumbent script is familiar with the browsing context A.
• The browsing context of the incumbent script is allowed to navigate the browsing context A.

A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a browsing context whose session history contains only one Document.

This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.

Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:

This method is only allowed to be called for windows that were opened by a script using the window.open method.

If you try to use window.close from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "Scripts may not close windows that were not opened by script."
Chrome: just silently fails.

The long-term solution:

The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.

However, since the security risks, posed by window.close, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.

The hacky workarounds:

Chrome is currently was vulnerable to the "self redirection" exploit. So code like this used to work in general:

open(location, '_self').close();

This is buggy behavior, IMO, and is now (as of roughly April 2015) mostly blocked. It will still work from injected code only if the tab is freshly opened and has no pages in the browsing history. So it's only useful in a very small set of circumstances.

However, a variation still works on Chrome (v43 & v44) plus Tampermonkey (v3.11 or later). Use an explicit @grant and plain window.close(). EG:

// ==UserScript==
// @name        window.close demo
// @include     http://YOUR_SERVER.COM/YOUR_PATH/*
// @grant       GM_addStyle
// ==/UserScript==

setTimeout (window.close, 5000);

Thanks to zanetu for the update. Note that this will not work if there is only one tab open. It only closes additional tabs.

Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.

You can open up about:config and set
allow_scripts_to_close_windows to true.

If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.

There currently is no equivalent setting for Chrome.

Need to convert the the key from hex to dec before base64_encoding and then send it for handshake.

You should change the line this.MyDateTime = myNewDT.MyDateTime.Value; to just this.MyDateTime = myNewDT.MyDateTime;

The exception you were receiving was thrown in the .Value property of the Nullable DateTime, as it is required to return a DateTime (since that's what the contract for .Value states), but it can't do so because there's no DateTime to return, so it throws an exception.

In general, it is a bad idea to blindly call .Value on a nullable type, unless you have some prior knowledge that that variable MUST contain a value (i.e. through a .HasValue check).

EDIT

Here's the code for DateTimeExtended that does not throw an exception:

class DateTimeExtended
{
    public DateTime? MyDateTime;
    public int? otherdata;

    public DateTimeExtended() { }

    public DateTimeExtended(DateTimeExtended other)
    {
        this.MyDateTime = other.MyDateTime;
        this.otherdata = other.otherdata;
    }
}

I tested it like this:

DateTimeExtended dt1 = new DateTimeExtended();
DateTimeExtended dt2 = new DateTimeExtended(dt1);

Adding the .Value on other.MyDateTime causes an exception. Removing it gets rid of the exception. I think you're looking in the wrong place.

Question 1: Unfortunately the one in which you you say is most intuitive is the least used in Android. As I understand, you should separate your UI (XML) and computational functionality (Java Class Files). It also makes for easier debugging. It is actually a lot easier to read this way and think about Android imo.

Question 2: I believe the two mainly used are #2 and #3. I will use a Button clickButton as an example.

2

is in the form of an anonymous class.

Button clickButton = (Button) findViewById(R.id.clickButton);
clickButton.setOnClickListener( new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                ***Do what you want with the click here***
            }
        });

This is my favorite as it has the onClick method right next to where the button variable was set with the findViewById. It seems very neat and tidy that everything that deals with this clickButton Button View is located here.

A con that my coworker comments, is that imagine you have many views that need onclick listener. You can see that your onCreate will get very long in length. So that why he likes to use:

3

Say you have, 5 clickButtons:

Make sure your Activity/Fragment implement OnClickListener

// in OnCreate

Button mClickButton1 = (Button)findViewById(R.id.clickButton1);
mClickButton1.setOnClickListener(this);
Button mClickButton2 = (Button)findViewById(R.id.clickButton2);
mClickButton2.setOnClickListener(this);
Button mClickButton3 = (Button)findViewById(R.id.clickButton3);
mClickButton3.setOnClickListener(this);
Button mClickButton4 = (Button)findViewById(R.id.clickButton4);
mClickButton4.setOnClickListener(this);
Button mClickButton5 = (Button)findViewById(R.id.clickButton5);
mClickButton5.setOnClickListener(this);


// somewhere else in your code

public void onClick(View v) {
    switch (v.getId()) {
        case  R.id.clickButton1: {
            // do something for button 1 click
            break;
        }

        case R.id.clickButton2: {
            // do something for button 2 click
            break;
        }

        //.... etc
    }
}

This way as my coworker explains is neater in his eyes, as all the onClick computation is handled in one place and not crowding the onCreate method. But the downside I see is, that the:

1. views themselves,
2. and any other object that might be located in onCreate used by the onClick method will have to be made into a field.

Let me know if you would like more information. I didn't answer your question fully because it is a pretty long question. And if I find some sites I will expand my answer, right now I'm just giving some experience.

Try using @Html.DropDownList instead:

<td>Account: </td>
<td>@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))</td>

@Html.DropDownListFor expects a lambda as its first argument, not a string for the ID as you specify.

Other than that, without knowing what getUserAccounts() consists of, suffice to say it needs to return some sort of collection (IEnumerable for example) that has at least 1 object in it. If it returns null the property in the ViewBag won't have anything.

Update (June 2016): I now try to support touch and mouse input on every resolution, since the device landscape is slowly blurring the lines between what things are and aren't touch devices. iPad Pros are touch-only with the resolution of a 13" laptop. Windows laptops now frequently come with touch screens.

Other similar SO answers (see other answer on this question) might have different ways to try to figure out what sort of device the user is using, but none of them are fool-proof. I encourage you to check those answers out if you absolutely need to try to determine the device.

iPhones, for one, ignore the handheld query (Source). And I wouldn't be surprised if other smartphones do, too, for similar reasons.

The current best way that I use to detect a mobile device is to know its width and use the corresponding media query to catch it. That link there lists some popular ones. A quick Google search would yield you any others you might need, I'm sure.

For more iPhone-specific ones (such as Retina display), check out that first link I posted.

Another way:

Checkout the branch you want to revert, then reset your local working copy back to the commit that you want to be the latest one on the remote server (everything after it will go bye-bye). To do this, in SourceTree, I right-clicked on the and selected "Reset BRANCHNAME to this commit".

Then navigate to your repository's local directory and run this command:

git -c diff.mnemonicprefix=false -c core.quotepath=false push -v -f -- tags REPOSITORY_NAME BRANCHNAME:BRANCHNAME 

This will erase all commits after the current one in your local repository but only for that one branch.

I think the project you are looking for is: https://github.com/sarxos/webcam-capture (I'm the author)

There is an example working exactly as you've described - after it's run, the window appear where, after you press "Start" button, you can see live image from webcam device and save it to file after you click on "Snapshot" (source code available, please note that FPS counter in the corner can be disabled):

The project is portable (WinXP, Win7, Win8, Linux, Mac, Raspberry Pi) and does not require any additional software to be installed on the PC.

API is really nice and easy to learn. Example how to capture single image and save it to PNG file:

Webcam webcam = Webcam.getDefault();
webcam.open();
ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));

From char and varchar (Transact-SQL)

varchar [ ( n | max ) ]

Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.

If animating opacity is not an option, you can also animate background-size.

For example, I used this CSS to set a backgound-image with a delay.

.before {
  background-size: 0;
}

.after {
  transition: background 0.1s step-end;
  background-image: $path-to-image;
  background-size: 20px 20px;
}

To simply remove everything that is not currently used by a running container the following alias, that I usually put into the .bash_profile on my Mac, will help:

alias dockerclean="docker ps -q -a | xargs docker rm -v && docker images -q | xargs docker rmi"

Whenever dockerclean is invoked from the command line it will remove stopped containers as well as unused image layers. For running containers and used images it will print a warning message and skip over it.

A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

1.- Export signed packages:

• Use the Extract a Signed Android Application Package Wizard (On the main menu, choose Build | Generate Signed APK). The package will be signed during extraction.

  OR

• Configure the .apk file as an artifact by creating an artifact definition of the type Android application with the Release signed package mode.

2.- Export unsigned packages: this can only be done through artifact definitions with the Debug or Release unsigned package mode specified.

You need some tools like pdf2text to first convert your pdf to a text file and then search inside the text. (You will probably miss some information or symbols).

If you are using a programming language there are probably pdf libraries written for this purpose. e.g. http://search.cpan.org/dist/CAM-PDF/ for Perl

if you just need it for db-related stuff, some OR Mappers (e.g. NHibernate) support transactinos out of the box per default.

I had same problem. After trying all these methods without success I did the following:

tail -f the-mysql-or-maria-db-error-file.err

in another console:

brew services restart mariadb

I saw the following error:

"MAC HOMEBREW Crash recovery failed. Either correct the problem (if it's, for example, out of memory error) and restart, or delete tc log and start mysqld with"

So I changed the tc.log extesion to tc.log.txt and restart mariadb

brew services restart mariadb

and done!

I have thesame issue before but i solved it easily by just following this steps:

*connect your android phone in a debugging mode (to enable debugging mode goto settings scroll down About Phone scroll down tap seven times Build Number and it will automatically enable developer option turn on developer options and check USB debugging)

download Universal ADB Driver Installer

*choose Adb Driver Installer (Universal)

*install it *it will automatically detect your android device(any kind of brand) *chose the device and install

Using the standard promise object, and having the promise return the results.

function promiseMap (data, f) {
  const reducer = (promise, x) =>
    promise.then(acc => f(x).then(y => acc.push(y) && acc))
  return data.reduce(reducer, Promise.resolve([]))
}

var emails = []

function getUser(email) {
  return db.getUser(email)
}

promiseMap(emails, getUser).then(emails => {
  console.log(emails)
})

1. Create multiple appSettings.$(Configuration).json files like:

   • appSettings.staging.json
   • appSettings.production.json

2. Create a pre-build event on the project which copies the respective file to appSettings.json:

   copy appSettings.$(Configuration).json appSettings.json
   

3. Use only appSettings.json in your Config Builder:

   var builder = new ConfigurationBuilder()
               .SetBasePath(env.ContentRootPath)
               .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
               .AddEnvironmentVariables();
   
   Configuration = builder.Build();
   

Html:

<input type="file" name="input-file" id="input-file">

jQuery:

var fileToUpload = $('#input-file').prop('files')[0];

We want to get first element only, because prop('files') returns array.

Initialize tSize to

tSize = ""  

before your if block to be safe. Also in your else case, put tSize in quotes so it is a string not an int. Also also you are comparing strings to ints.

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

subscribe() -Invokes an execution of an Observable and registers Observer handlers for notifications it will emit. -Observable- representation of any set of values over any amount of time.

I had the same issue, but I have resolved it the next:

1) Install jdk1.8...

2) In AndroidStudio File->Project Structure->SDK Location, select your directory where the JDK is located, by default Studio uses embedded JDK but for some reason it produces error=216.

3) Click Ok.

Stopping OpenSdk Java process (inner to Android Studio process) worked.

this is what i used:

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];

NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init];
[timeFormat setDateFormat:@"HH:mm:ss"];

NSDate *now = [[NSDate alloc] init];

NSString *theDate = [dateFormat stringFromDate:now];
NSString *theTime = [timeFormat stringFromDate:now];

NSLog(@"\n"
      "theDate: |%@| \n"
      "theTime: |%@| \n"
      , theDate, theTime);

[dateFormat release];
[timeFormat release];
[now release];

You can do it with grep alone (without find).

grep -riL "foo" .

This is the explanation of the parameters used on grep

     -L, --files-without-match
             each file processed.
     -R, -r, --recursive
             Recursively search subdirectories listed.

     -i, --ignore-case
             Perform case insensitive matching.

If you use l (lowercased) you will get the opposite (files with matches)

     -l, --files-with-matches
             Only the names of files containing selected lines are written

SELECT *
FROM sys.tables t
INNER JOIN sys.objects o on o.object_id = t.object_id
WHERE o.is_ms_shipped = 0;

Using execComand:

<input type="button" name="save" value="Save" onclick="javascript:document.execCommand('SaveAs','true','your_file.txt')">

In the next link: execCommand

Using join Another variation is to use join. Now the query could look like:

    SELECT a.id, a.value, SUM(b.Value)FROM   RunTotalTestData a,
    RunTotalTestData b
    WHERE b.id <= a.id
    GROUP BY a.id, a.value 
    ORDER BY a.id;

for more you can visite this link http://askme.indianyouth.info/details/calculating-simple-running-totals-in-sql-server-12

You can use TRIM('"' FROM '"this "is" a test"') which returns: this "is" a test

To create a new empty column and fill it with the same value (here 100) for every row (in Toad for Oracle):

ALTER TABLE my_table ADD new_column INT;
UPDATE my_table SET new_column = 100;

Web Hosting Challenge

You have to remember that none of the machine configuration options are available if you are hosted on a shared server as many of us (smaller companies and individuals) are.

ASP.NET MVC Overhead

My site takes at least 30 seconds when it hasn't been hit in over 20 minutes (and the web app has been stopped). It is terrible.

Another Way to Test Performance

There's another way to test if it is your ASP.NET MVC start up or something else. Drop a normal HTML page on your site where you can hit it directly.
If the problem is related to ASP.NET MVC start up then the HTML page will render almost immediately even when the web app hasn't been started.
That's how I first recognized that the problem was in the ASP.NET MVC startup. I loaded an HTML page at any time and it would load blazing fast. Then, after hitting that HTML page I'd hit one of my ASP.NET MVC URLs and I'd get the Chrome message "Waiting for raddev.us..."

Another Test With Helpful Script

After that I wrote a LINQPad (check out http://linqpad.net for more) script that would hit my web site every 8 minutes (less than the time for the app to unload -- which should be 20 minutes) and I let it run for hours.

While the script was running I hit my web site and every time my site came up blazingly fast. This gives me a good idea that most likely the slowness I was experiencing was because of ASP.NET MVC startup times.

Get LinqPad and you can run the following script -- just change the URL to your own and let it run and you can test this easily. Good luck.

NOTE: In LinqPad you'll need to press F4 and add a reference to System.Net to add the library which will retrieve your page.

ALSO : make sure you change the String URL variable to point at a URL that will load a route from your ASP.NET MVC site so the engine will run.

I had the same problem... a JDK and plug-in version conflict.

I compiled using 1.8 ... the latest one, and that message started to appear. So I've searched for the JRE 7 (http://www.oracle.com/technetwork/java/javase/downloads/server-jre7-downloads-1931105.html)... and installed it... again... Now 1.8 and 1.7 in the same computer.

Using NetBeans, and compiling, and targeting to version 1.7, fixed my problem.

To rotate a DIV Make use of WebkitTransform / -moz-transform: rotate(Xdeg).

This will not work in IE. The Raphael library does work with IE and it does rotation. I believe it uses canvases

If you want to animate the rotation, you can use a recursive setTimeout()

You could probably even do part of a spin with jQuery's .animate()

Make sure that you consider the width of your element. If rotate an that has a larger width than its visible content, you'll get funny results. However you can narrow the widths of elements, and then rotate them.

Here is a simply jQuery snippet that rotates the elements in a jQuery object. Rotatation can be started and stopped:

$(function() {
    var $elie = $(selectorForElementsToRotate);
    rotate(0);
    function rotate(degree) {

          // For webkit browsers: e.g. Chrome
        $elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
          // For Mozilla browser: e.g. Firefox
        $elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});

          // Animate rotation with a recursive call
        setTimeout(function() { rotate(++degree); },5);
    }
});

jsFiddle example

Note:
Taking the degree and increasing it, will rotate the image clockwise. Decreasing the degree of rotation will rotate the image counter clockwise.

You could also just use the bytes where they are, casting them to the type you need.

unsigned char *bytePtr = (unsigned char *)[data bytes];

A very simple example:

SET a=Hello
SET b=World
SET c=%a% %b%!
echo %c%

The result should be:

Hello World!

No one said a pure xaml solution has to be complicated. Here's a simple one, with 1 data trigger on the text box. Margin and position as desired

<Grid>
    <ComboBox x:Name="mybox" ItemsSource="{Binding}"/>
    <TextBlock Text="Select Something" IsHitTestVisible="False">
           <TextBlock.Style>
                <Style TargetType="TextBlock">
                      <Setter Property="Visibility" Value="Hidden"/>
                      <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=mybox,Path=SelectedItem}" Value="{x:Null}">
                                  <Setter Property="Visibility" Value="Visible"/>
                             </DataTrigger>
                      </Style.Triggers>
                </Style>
           </TextBlock.Style>
     </TextBlock>
</Grid>

I've tested in my own shell script.

...long time ago in a faraway place philosophers worried about the distinction between the one and the many. Architecture is about relationship, which requires the many. Architecture has components. Design is about content, which requires the one. Design has properties, qualities, characteristics. We typically think that design is within architecture. Dualistic thinking gives the many as primordial. But architecture is also within design. It's all how we choose to view what is before us - the one or the many.

1. I recommend and use TouchJSON for parsing JSON.

2. To answer your comment to Alex. Here's quick code that should allow you to get the fields like activity_details, last_name, etc. from the json dictionary that is returned:

   NSDictionary *userinfo=[jsondic valueforKey:@"#data"];
   NSDictionary *user;
   NSInteger i = 0;
   NSString *skey;
   if(userinfo != nil){
       for( i = 0; i < [userinfo count]; i++ ) {
           if(i)
               skey = [NSString stringWithFormat:@"%d",i];
           else
               skey = @"";
   
           user = [userinfo objectForKey:skey];
           NSLog(@"activity_details:%@",[user objectForKey:@"activity_details"]);
           NSLog(@"last_name:%@",[user objectForKey:@"last_name"]);
           NSLog(@"first_name:%@",[user objectForKey:@"first_name"]);
           NSLog(@"photo_url:%@",[user objectForKey:@"photo_url"]);
       }
   }
   

The File class represents the "idea" of a file, not an actual handle to use for I/O. This is why the File class has a .exists() method, to tell you if the file exists or not. (How can you have a File object that doesn't exist?)

By contrast, constructing a new FileInputStream(new File("/my/file")) gives you an actual stream to read bytes from.

Server id should match with the repository id of maven settings.xml

With the use of Google Guava:

import com.google.common.base.Charsets;
import com.google.common.io.Resources;

public String readResource(final String fileName, Charset charset) throws Exception {
        try {
            return Resources.toString(Resources.getResource(fileName), charset);
        } catch (IOException e) {
            throw new IllegalArgumentException(e);
        }
}

Example:

String fixture = this.readResource("filename.txt", Charsets.UTF_8)

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

do this way :

sudo apt purge ruby

Another approach to remove the first line from file, using multiple assignment technique. Refer Link

 $firstLine, $restOfDocument = Get-Content -Path $filename 
 $modifiedContent = $restOfDocument 
 $modifiedContent | Out-String | Set-Content $filename

I got the exact path using:

netstat -ln | grep -o -m 1 -E '\S*mysqld?\.sock'

Since this only returns the path and doesn't require any input you could potentially use it in a shell script.

MySQL must be currently running on your machine for this to work. Works for MariaDB too.

Workaround

You can do this using Javascript:

<html><head>
<script type="text/javascript">
function logout() {
    var xmlhttp;
    if (window.XMLHttpRequest) {
          xmlhttp = new XMLHttpRequest();
    }
    // code for IE
    else if (window.ActiveXObject) {
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    if (window.ActiveXObject) {
      // IE clear HTTP Authentication
      document.execCommand("ClearAuthenticationCache");
      window.location.href='/where/to/redirect';
    } else {
        xmlhttp.open("GET", '/path/that/will/return/200/OK', true, "logout", "logout");
        xmlhttp.send("");
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4) {window.location.href='/where/to/redirect';}
        }


    }


    return false;
}
</script>
</head>
<body>
<a href="#" onclick="logout();">Log out</a>
</body>
</html>

What is done above is:

• for IE - just clear auth cache and redirect somewhere

• for other browsers - send an XMLHttpRequest behind the scenes with 'logout' login name and password. We need to send it to some path that will return 200 OK to that request (i.e. it shouldn't require HTTP authentication).

Replace '/where/to/redirect' with some path to redirect to after logging out and replace '/path/that/will/return/200/OK' with some path on your site that will return 200 OK.

Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

The simplest and fastest way is the following (if you have not changed the defaults folder for DerivedData).

Open terminal and past the following:

rm -rf ~/Library/Developer/Xcode/DerivedData

When using Navicat you can go to types (under view -> others -> types) - get the design view of the type - and click the "add label" button.

Do this with a file stream. When a std::ofstream is closed, the file is created. I personally like the following code, because the OP only asks to create a file, not to write in it:

#include <fstream>

int main()
{
    std::ofstream file { "Hello.txt" };
    // Hello.txt has been created here
}

The temporary variable file is destroyed right after its creation, so the stream is closed and thus the file is created.

I needed this instead of using padding because I used inline-block containers to display a series of individual events in a workflow timeline. The last event in the timeline needed no arrow after it.

Ended up with something like:

.transaction-tile:after {
  content: "\f105";
}

.transaction-tile:last-child:after {
  content: "\00a0";
}

Used fontawesome for the gt (chevron) character. For whatever reason "content: none;" was producing alignment issues on the last tile.

Simple.

Assuming that in your Activity-1, you did this:

String stringExtra = "Some string you want to pass";

Intent intent = new Intent(this, AndroidTabRestaurantDescSearchListView.class);

//include the string in your intent
intent.putExtra("string", stringExtra);

startActivity(intent);

And in your AndroidTabRestaurantDescSearchListView class, do this:

//fetch the string  from the intent
String extraFromAct1 = getIntent().getStringExtra("string");

Intent intent = new Intent(this, RatingDescriptionSearchActivity.class);

//attach same string and send it with the intent
intent.putExtra("string", extraFromAct1);
startActivity(intent);

Then in your RatingDescriptionSearchActivity class, do this:

String extraFromAct1 = getIntent().getStringExtra("string");

I tried to create a mapped network driver via 'net use' with admin privilege but failed, it does not show. And if I add it through UI, it disappeared after reboot, now I made that through powershell. So, I think you can run powershell scripts from a .bat file, and the script is

New-PSDrive -Name "P" -PSProvider "FileSystem" -Root "\\Server01\Public"

add -persist at the end, you will create a persisted mapped network drive

New-PSDrive -Name "P" -PSProvider "FileSystem" -Root "\\Server01\Scripts" -Persist

for more details, refer New-PSDrive - Microsoft Docs

This is probably the easiest way:

new Date(<your-date-object>.toDateString());

Example: To get the Current Date without time component:

new Date(new Date().toDateString());

gives: Thu Jul 11 2019 00:00:00 GMT-0400 (Eastern Daylight Time)

Note this works universally, because toDateString() produces date string with your browser's localization (without the time component), and the new Date() uses the same localization to parse that date string.

You need to enclose your <parent> elements in a surrounding element as XML Documents can have only one root node:

<parents> <!-- I've added this tag -->
    <parent>
        <child>
            Text
        </child>
    </parent>
    <parent>
        <child>
            <grandchild>
                Text
            </grandchild>
            <grandchild>
                Text
            </grandchild>
        </child>
        <child>
            Text
        </child>
    </parent>
</parents> <!-- I've added this tag -->

As you're receiving this markup from somewhere else, rather than generating it yourself, you may have to do this yourself by treating the response as a string and wrapping it with appropriate tags, prior to attempting to parse it as XML.

So, you've a couple of choices:

1. Get the provider of the web service to return you actual XML that has one root node
2. Pre-process the XML, as I've suggested above, to add a root node
3. Pre-process the XML to split it into multiple chunks (i.e. one for each <parent> node) and process each as a distinct XML Document

Do not forget to clear the cache after updating the external_url param in /etc/gitlab/gitlab.rb, otherwise your existing project clone URLs will still be showing your old host name.

A simple 3 step process to change the hostname is as follows

• update the external_url param in /etc/gitlab/gitlab.rb
• sudo gitlab-ctl reconfigure
• sudo gitlab-ctl restart
• sudo gitlab-rake cache:clear

Just apply scroll behaviour to all elements with this one-line code:

*{
scroll-behavior: smooth !important;
}

Set specific tab index as active:

$(this).tabs({ active: # }); /* Where # is the tab index. The index count starts at 0 */

Set last tab as active

$(this).tabs({ active: -1 });

Set specific tab by ID:

$(this).tabs({ active: $('a[href="#tab-101"]').parent().index() });

I wrote the following code that works fine. But I think it only works with .wav format.

public static synchronized void playSound(final String url) {
  new Thread(new Runnable() {
  // The wrapper thread is unnecessary, unless it blocks on the
  // Clip finishing; see comments.
    public void run() {
      try {
        Clip clip = AudioSystem.getClip();
        AudioInputStream inputStream = AudioSystem.getAudioInputStream(
          Main.class.getResourceAsStream("/path/to/sounds/" + url));
        clip.open(inputStream);
        clip.start(); 
      } catch (Exception e) {
        System.err.println(e.getMessage());
      }
    }
  }).start();
}

I had the same problem. Try to make a bat-file to start the Qt Creator. Add something like this to the bat-file:

call "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat"  
"C:\QTsdk\qtcreator\bin\qtcreator" 

Now I can compile and get:

jom 1.0.8 - empower your cores
11:10:08: The process "C:\QTsdk\qtcreator\bin\jom.exe" exited normally.

I've extended vokimon's answer a bit, making it a bit more convenient for changing other properties as well.

function customIcon (opts) {
  return Object.assign({
    path: 'M 0,0 C -2,-20 -10,-22 -10,-30 A 10,10 0 1,1 10,-30 C 10,-22 2,-20 0,0 z M -2,-30 a 2,2 0 1,1 4,0 2,2 0 1,1 -4,0',
    fillColor: '#34495e',
    fillOpacity: 1,
    strokeColor: '#000',
    strokeWeight: 2,
    scale: 1,
  }, opts);
}

Usage:

marker.setIcon(customIcon({
  fillColor: '#fff',
  strokeColor: '#000'
}));

Or when defining a new marker:

const marker = new google.maps.Marker({
  position: {
    lat: ...,
    lng: ...
  },
  icon: customIcon({
    fillColor: '#2ecc71'
  }),
  map: map
});

It sounds like you'd be happer with a single table. The five having the same schema, and sometimes needing to be presented as if they came from one table point to putting it all in one table.

Add a new column which can be used to distinguish among the five languages (I'm assuming it's language that is different among the tables since you said it was for localization). Don't worry about having 4.5 million records. Any real database can handle that size no problem. Add the correct indexes, and you'll have no trouble dealing with them as a single table.

I know this is an older question, but I felt the answer from t3chb0t led me to the best path and felt like sharing. You don't even need to go so far as implementing all the formatter's methods. I did the following for the content-type "application/vnd.api+json" being returned by an API I was using:

public class VndApiJsonMediaTypeFormatter : JsonMediaTypeFormatter
{
    public VndApiJsonMediaTypeFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/vnd.api+json"));
    }
}

Which can be used simply like the following:

HttpClient httpClient = new HttpClient("http://api.someaddress.com/");
HttpResponseMessage response = await httpClient.GetAsync("person");

List<System.Net.Http.Formatting.MediaTypeFormatter> formatters = new List<System.Net.Http.Formatting.MediaTypeFormatter>();
formatters.Add(new System.Net.Http.Formatting.JsonMediaTypeFormatter());
formatters.Add(new VndApiJsonMediaTypeFormatter());

var responseObject = await response.Content.ReadAsAsync<Person>(formatters);

Super simple and works exactly as I expected.

In your controller class, just add @ComponentScan("package") annotation. In my case the package name is com.shoppingcart.So i wrote the code as @ComponentScan("com.shoppingcart") and it worked for me.

@@ denotes a class variable, i.e. it can be inherited.

This means that if you create a subclass of that class, it will inherit the variable. So if you have a class Vehicle with the class variable @@number_of_wheels then if you create a class Car < Vehicle then it too will have the class variable @@number_of_wheels

I'm using Bootstrap 4 and Dennis Puzak's solution does not work for me.

The next solution works for me

.form-control::placeholder { color: white;} /* Chrome, Firefox, Opera*/
:-ms-input-placeholder.form-control { color: white; }  /* Internet Explorer*/
.form-control::-ms-input-placeholder { color: white; }  /* Microsoft Edge*/

You can also use

From String to Date

String dtStart = "2010-10-15T09:27:37Z";  
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    Date date = format.parse(dtStart);  
    System.out.println(date);  
} catch (ParseException e) {
    e.printStackTrace();  
}

From Date to String

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    Date date = new Date();  
    String dateTime = dateFormat.format(date);
    System.out.println("Current Date Time : " + dateTime); 
} catch (ParseException e) {
    e.printStackTrace();  
}

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

Having tackled this same problem myself today, I'd like to present a solution that (currently) works on the major browsers. Some of the other answers on this page did work once, but recent updates, whether it be browser or OS, have voided most/all of these answers.

The key is to place the image in a container, and to transform:scale that container out of it's overflow:hidden parent. Then, the blur gets applied to the img inside the container, instead of on the container itself.

    filter         : blur(15px);

From the Python PEP 8 -- Style Guide for Python Code:

Descriptive: Naming Styles

The following special forms using leading or trailing underscores are recognized (these can generally be combined with any case convention):

• _single_leading_underscore: weak "internal use" indicator. E.g. from M import * does not import objects whose name starts with an underscore.

• single_trailing_underscore_: used by convention to avoid conflicts with Python keyword, e.g.

  Tkinter.Toplevel(master, class_='ClassName')

• __double_leading_underscore: when naming a class attribute, invokes name mangling (inside class FooBar, __boo becomes _FooBar__boo; see below).

• __double_leading_and_trailing_underscore__: "magic" objects or attributes that live in user-controlled namespaces. E.g. __init__, __import__ or __file__. Never invent such names; only use them as documented.

Note that names with double leading and trailing underscores are essentially reserved for Python itself: "Never invent such names; only use them as documented".

You mean

if (isset($_POST['sms_code']) == TRUE ) {

though incidentally you really mean

if (isset($_POST['sms_code'])) {

Ran into this issue today (Excel crashes on adding rows using .ListRows.Add). After reading this post and checking my table, I realized the calculations of the formula's in some of the cells in the row depend on a value in other cells. In my case of cells in a higher column AND even cells with a formula!

The solution was to fill the new added row from back to front, so calculations would not go wrong.

Excel normally can deal with formula's in different cells, but it seems adding a row in a table kicks of a recalculation in order of the columns (A,B,C,etc..).

Hope this helps clearing issues with .ListRows.Add

Or you can write your own extension method:

static partial class Extensions
{
    public static T WhereMax<T, U>(this IEnumerable<T> items, Func<T, U> selector)
    {
        if (!items.Any())
        {
            throw new InvalidOperationException("Empty input sequence");
        }

        var comparer = Comparer<U>.Default;
        T   maxItem  = items.First();
        U   maxValue = selector(maxItem);

        foreach (T item in items.Skip(1))
        {
            // Get the value of the item and compare it to the current max.
            U value = selector(item);
            if (comparer.Compare(value, maxValue) > 0)
            {
                maxValue = value;
                maxItem  = item;
            }
        }

        return maxItem;
    }
}

stack size can indeed be unlimited. _STK_LIM is the default, _STK_LIM_MAX is something that differs per architecture, as can be seen from include/asm-generic/resource.h:

/*
 * RLIMIT_STACK default maximum - some architectures override it:
 */
#ifndef _STK_LIM_MAX
# define _STK_LIM_MAX           RLIM_INFINITY
#endif

As can be seen from this example generic value is infinite, where RLIM_INFINITY is, again, in generic case defined as:

/*
 * SuS says limits have to be unsigned.
 * Which makes a ton more sense anyway.
 *
 * Some architectures override this (for compatibility reasons):
 */
#ifndef RLIM_INFINITY
# define RLIM_INFINITY          (~0UL)
#endif

So I guess the real answer is - stack size CAN be limited by some architecture, then unlimited stack trace will mean whatever _STK_LIM_MAX is defined to, and in case it's infinity - it is infinite. For details on what it means to set it to infinite and what implications it might have, refer to the other answer, it's way better than mine.

This is a very rich and useful compilation, however, I am a bit surprised I have not encountered Andrew S. Tanenbaum among the authors. IMO he is one of the best CS professors, and his genius has to do mainly with his extraordinary ability in making rather difficult material accessible to the CS undergraduates. His books (Modern Operating Systems, or Computer Networks might ring a bell) did a wonderful job in providing me with a solid foundation in CS while doing my BS and I highly recommend them. Some other interesting stuff on Tanenbaum, proving his skills go beyond teaching: author of an OS called MINIX - Linus had his fare share of inspiration from it when implementing Linux; Amoeba - distributed OS; Turtle - free anonymous p2p network.

I created simple examples to clarify understanding of ManualResetEvent vs AutoResetEvent.

AutoResetEvent: lets assume you have 3 workers thread. If any of those threads will call WaitOne() all other 2 threads will stop execution and wait for signal. I am assuming they are using WaitOne(). It is like; if I do not work, nobody works. In first example you can see that

autoReset.Set();
Thread.Sleep(1000);
autoReset.Set();

When you call Set() all threads will work and wait for signal. After 1 second I am sending second signal and they execute and wait (WaitOne()). Think about these guys are soccer team players and if one player says I will wait until manager calls me, and others will wait until manager tells them to continue (Set())

public class AutoResetEventSample
{
    private AutoResetEvent autoReset = new AutoResetEvent(false);

    public void RunAll()
    {
        new Thread(Worker1).Start();
        new Thread(Worker2).Start();
        new Thread(Worker3).Start();
        autoReset.Set();
        Thread.Sleep(1000);
        autoReset.Set();
        Console.WriteLine("Main thread reached to end.");
    }

    public void Worker1()
    {
        Console.WriteLine("Entered in worker 1");
        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker1 is running {0}", i);
            Thread.Sleep(2000);
            autoReset.WaitOne();
        }
    }
    public void Worker2()
    {
        Console.WriteLine("Entered in worker 2");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker2 is running {0}", i);
            Thread.Sleep(2000);
            autoReset.WaitOne();
        }
    }
    public void Worker3()
    {
        Console.WriteLine("Entered in worker 3");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker3 is running {0}", i);
            Thread.Sleep(2000);
            autoReset.WaitOne();
        }
    }
}

In this example you can clearly see that when you first hit Set() it will let all threads go, then after 1 second it signals all threads to wait! As soon as you set them again regardless they are calling WaitOne() inside, they will keep running because you have to manually call Reset() to stop them all.

manualReset.Set();
Thread.Sleep(1000);
manualReset.Reset();
Console.WriteLine("Press to release all threads.");
Console.ReadLine();
manualReset.Set();

It is more about Referee/Players relationship there regardless of any of the player is injured and wait for playing others will continue to work. If Referee says wait (Reset()) then all players will wait until next signal.

public class ManualResetEventSample
{
    private ManualResetEvent manualReset = new ManualResetEvent(false);

    public void RunAll()
    {
        new Thread(Worker1).Start();
        new Thread(Worker2).Start();
        new Thread(Worker3).Start();
        manualReset.Set();
        Thread.Sleep(1000);
        manualReset.Reset();
        Console.WriteLine("Press to release all threads.");
        Console.ReadLine();
        manualReset.Set();
        Console.WriteLine("Main thread reached to end.");
    }

    public void Worker1()
    {
        Console.WriteLine("Entered in worker 1");
        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker1 is running {0}", i);
            Thread.Sleep(2000);
            manualReset.WaitOne();
        }
    }
    public void Worker2()
    {
        Console.WriteLine("Entered in worker 2");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker2 is running {0}", i);
            Thread.Sleep(2000);
            manualReset.WaitOne();
        }
    }
    public void Worker3()
    {
        Console.WriteLine("Entered in worker 3");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker3 is running {0}", i);
            Thread.Sleep(2000);
            manualReset.WaitOne();
        }
    }
}

That should work:

function get_content(){
   var p = document.getElementById("txt");
   var spans = p.getElementsByTagName("span");
   var text = '';
   for (var i = 0; i < spans.length; i++){
       text += spans[i].innerHTML;
   }

   p.innerHTML = text;
}

The way how I'm handling the Divider view and also Divider Insets is by adding a RecyclerView extension.

1.

Add a new extension file by naming View or RecyclerView:

RecyclerViewExtension.kt

and add the setDivider extension method inside the RecyclerViewExtension.kt file.

/*
* RecyclerViewExtension.kt
* */
import androidx.annotation.DrawableRes
import androidx.core.content.ContextCompat
import androidx.recyclerview.widget.DividerItemDecoration
import androidx.recyclerview.widget.RecyclerView


fun RecyclerView.setDivider(@DrawableRes drawableRes: Int) {
    val divider = DividerItemDecoration(
        this.context,
        DividerItemDecoration.VERTICAL
    )
    val drawable = ContextCompat.getDrawable(
        this.context,
        drawableRes
    )
    drawable?.let {
        divider.setDrawable(it)
        addItemDecoration(divider)
    }
}

2.

Create a Drawable resource file inside of drawable package like recycler_view_divider.xml:

<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="10dp"
    android:insetRight="10dp">

    <shape>
        <size android:height="0.5dp" />
        <solid android:color="@android:color/darker_gray" />
    </shape>

</inset>

where you can specify the left and right margin on android:insetLeft and android:insetRight.

3.

On your Activity or Fragment where the RecyclerView is initialized, you can set the custom drawable by calling:

recyclerView.setDivider(R.drawable.recycler_view_divider)

4.

I tried placing a label with transparent background over a progress bar but never got it to work properly. So I found Barry's solution here very useful, although I missed the beautiful Vista style progress bar. So I merged Barry's solution with http://www.dreamincode.net/forums/topic/243621-percent-into-progress-bar/ and managed to keep the native progress bar, while displaying text percentage or custom text over it. I don't see any flickering in this solution either. Sorry to dig up and old thread but I needed this today and so others may need it too.

public enum ProgressBarDisplayText
{
    Percentage,
    CustomText
}

class ProgressBarWithCaption : ProgressBar
{
    //Property to set to decide whether to print a % or Text
    private ProgressBarDisplayText m_DisplayStyle;
    public ProgressBarDisplayText DisplayStyle {
        get { return m_DisplayStyle; }
        set { m_DisplayStyle = value; }
    }

    //Property to hold the custom text
    private string m_CustomText;
    public string CustomText {
        get { return m_CustomText; }
        set {
            m_CustomText = value;

Make sure that your query ran successfully and you got the results. You can check like this:

$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']) or die(mysql_error());


if (is_resource($result))
{
   // your while loop and fetch array function here....
}

How about this?

=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))

The "3" at the end means for column C.

I had some strings in the MongoDB Stored wich had to be reformated to a proper and valid dateTime field in the mongodb.

here is my code for the special date format: "2014-03-12T09:14:19.5303017+01:00"

but you can easyly take this idea and write your own regex to parse the date formats:

// format: "2014-03-12T09:14:19.5303017+01:00"
var myregexp = /(....)-(..)-(..)T(..):(..):(..)\.(.+)([\+-])(..)/;

db.Product.find().forEach(function(doc) { 
   var matches = myregexp.exec(doc.metadata.insertTime);

   if myregexp.test(doc.metadata.insertTime)) {
       var offset = matches[9] * (matches[8] == "+" ? 1 : -1);
       var hours = matches[4]-(-offset)+1
       var date = new Date(matches[1], matches[2]-1, matches[3],hours, matches[5], matches[6], matches[7] / 10000.0)
       db.Product.update({_id : doc._id}, {$set : {"metadata.insertTime" : date}})
       print("succsessfully updated");
    } else {
        print("not updated");
    }
})

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

No, a List<Dog> is not a List<Animal>. Consider what you can do with a List<Animal> - you can add any animal to it... including a cat. Now, can you logically add a cat to a litter of puppies? Absolutely not.

// Illegal code - because otherwise life would be Bad
List<Dog> dogs = new ArrayList<Dog>(); // ArrayList implements List
List<Animal> animals = dogs; // Awooga awooga
animals.add(new Cat());
Dog dog = dogs.get(0); // This should be safe, right?

Suddenly you have a very confused cat.

Now, you can't add a Cat to a List<? extends Animal> because you don't know it's a List<Cat>. You can retrieve a value and know that it will be an Animal, but you can't add arbitrary animals. The reverse is true for List<? super Animal> - in that case you can add an Animal to it safely, but you don't know anything about what might be retrieved from it, because it could be a List<Object>.

There are so many good answers here already, but i just want to show with an example that you can add additional functionality to the class being extended;

function applyMixins(derivedCtor: any, baseCtors: any[]) {
    baseCtors.forEach(baseCtor => {
        Object.getOwnPropertyNames(baseCtor.prototype).forEach(name => {
            if (name !== 'constructor') {
                derivedCtor.prototype[name] = baseCtor.prototype[name];
            }
        });
    });
}

class Class1 {
    doWork() {
        console.log('Working');
    }
}

class Class2 {
    sleep() {
        console.log('Sleeping');
    }
}

class FatClass implements Class1, Class2 {
    doWork: () => void = () => { };
    sleep: () => void = () => { };


    x: number = 23;
    private _z: number = 80;

    get z(): number {
        return this._z;
    }

    set z(newZ) {
        this._z = newZ;
    }

    saySomething(y: string) {
        console.log(`Just saying ${y}...`);
    }
}
applyMixins(FatClass, [Class1, Class2]);


let fatClass = new FatClass();

fatClass.doWork();
fatClass.saySomething("nothing");
console.log(fatClass.x);

Another solution from codeConcussion (https://stackoverflow.com/a/7265394/2793768)

var param = "Address";    
var pi = typeof(Student).GetProperty(param);    
var orderByAddress = items.OrderBy(x => pi.GetValue(x, null));

I though that was a pretty reasonable request but it looks like you cant do it at this time. What a Total Failure. lol

Update

You can now use textAllCaps to force all caps.

When inserting a row, regardless of the CopyOrigin, Excel will only put vertical borders on the inserted cells if the borders above and below the insert position are the same.

I'm running into a similar (but rotated) situation with inserting columns, but Copy/Paste is too slow for my workbook (tens of thousands of rows, many columns, and complex formatting).

I've found three workarounds that don't require copying the formatting from the source row:

1. Ensure the vertical borders are the same weight, color, and pattern above and below the insert position so Excel will replicate them in your new row. (This is the "It hurts when I do this," "Stop doing that!" answer.)

2. Use conditional formatting to establish the border (with a Formula of "=TRUE"). The conditional formatting will be copied to the new row, so you still end up with a border.Caveats:

   • Conditional formatting borders are limited to the thin-weight lines.
   • Works best for sheets where borders are relatively consistent so you don't have to create a bunch of conditional formatting rules.

3. Set the border on the inserted row in VBA after inserting the row. Setting a border on a range is much faster than copying and pasting all of the formatting just to get a border (assuming you know ahead of time what the border should be or can sample it from the row above without losing performance).

declare @d real
set @d=1.0;
select @d*40000*(192+2)*20000+150000

In my case it was due to 'lower_case_table_names' parameter.

The error number 39 thrown out when I tried to drop the databases which consists upper case table names with lower_case_table_names parameter is enabled.

This is fixed by reverting back the lower case parameter changes to the previous state.

1. fork() - creates a new child process, which is a complete copy of the parent process. Child and parent processes use different virtual address spaces, which is initially populated by the same memory pages. Then, as both processes are executed, the virtual address spaces begin to differ more and more, because the operating system performs a lazy copying of memory pages that are being written by either of these two processes and assigns an independent copies of the modified pages of memory for each process. This technique is called Copy-On-Write (COW).
2. vfork() - creates a new child process, which is a "quick" copy of the parent process. In contrast to the system call fork(), child and parent processes share the same virtual address space. NOTE! Using the same virtual address space, both the parent and child use the same stack, the stack pointer and the instruction pointer, as in the case of the classic fork()! To prevent unwanted interference between parent and child, which use the same stack, execution of the parent process is frozen until the child will call either exec() (create a new virtual address space and a transition to a different stack) or _exit() (termination of the process execution). vfork() is the optimization of fork() for "fork-and-exec" model. It can be performed 4-5 times faster than the fork(), because unlike the fork() (even with COW kept in the mind), implementation of vfork() system call does not include the creation of a new address space (the allocation and setting up of new page directories).
3. clone() - creates a new child process. Various parameters of this system call, specify which parts of the parent process must be copied into the child process and which parts will be shared between them. As a result, this system call can be used to create all kinds of execution entities, starting from threads and finishing by completely independent processes. In fact, clone() system call is the base which is used for the implementation of pthread_create() and all the family of the fork() system calls.
4. exec() - resets all the memory of the process, loads and parses specified executable binary, sets up new stack and passes control to the entry point of the loaded executable. This system call never return control to the caller and serves for loading of a new program to the already existing process. This system call with fork() system call together form a classical UNIX process management model called "fork-and-exec".

This is caused when your request response is not received in given time(by timeout request module option).

Basically to catch that error first, you need to register a handler on error, so the unhandled error won't be thrown anymore: out.on('error', function (err) { /* handle errors here */ }). Some more explanation here.

In the handler you can check if the error is ETIMEDOUT and apply your own logic: if (err.message.code === 'ETIMEDOUT') { /* apply logic */ }.

If you want to request for the file again, I suggest using node-retry or node-backoff modules. It makes things much simpler.

If you want to wait longer, you can set timeout option of request yourself. You can set it to 0 for no timeout.

         public String hashString(String s) throws NoSuchAlgorithmException {
    byte[] hash = null;
    try {
        MessageDigest md = MessageDigest.getInstance("SHA-256");
        hash = md.digest(s.getBytes());

    } catch (NoSuchAlgorithmException e) { e.printStackTrace(); }
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < hash.length; ++i) {
        String hex = Integer.toHexString(hash[i]);
        if (hex.length() == 1) {
            sb.append(0);
            sb.append(hex.charAt(hex.length() - 1));
        } else {
            sb.append(hex.substring(hex.length() - 2));
        }
    }
    return sb.toString();
}

Yes, you can specify the notebooks location in your profile configuration. Since it's not saving them to the directory where you started the notebook, I assume that you have this option set in your profile. You can find out the the path to the profiles directory by using:

$ ipython locate

Either in your default profile or in the profile you use, edit the ipython_notebook_config.py file and change the lines:

Note: In case you don't have a profile, or the profile folder does not contain the ipython_notebook_config.py file, use ipython profile create.

# The directory to use for notebooks.
c.NotebookManager.notebook_dir = u'/path/to/your/notebooks'

and

# The directory to use for notebooks.
c.FileNotebookManager.notebook_dir = u'/path/to/your/notebooks'

Or just comment them out if you want the notebooks saved in the current directory.

Update (April 11th 2014): in IPython 2.0 the property name in the config file changed, so it's now:

c.NotebookApp.notebook_dir = u'/path/to/your/notebooks'

Put the select statement in a dynamic PL/SQL block.

CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2)

  v_query_str VARCHAR2(1000);
  v_num_of_employees NUMBER;

  v_query_str := 'begin SELECT COUNT(*) INTO :into_bind FROM emp_' 
                 || p_loc
                 || ' WHERE job = :bind_job; end;';
  EXECUTE IMMEDIATE v_query_str
    USING out v_num_of_employees, p_job;
  RETURN v_num_of_employees;

Try this:

If you have already created your user, you might have created your user with the wrong password.

So drop that user and create another user by doing this. To see your current users.

SELECT Host,User FROM mysql.user;

To drop the user

DROP User '<your-username>'@'localhost';

After this you can create the user again with the correct password

CREATE USER '<your-username>'@'localhost' IDENTIFIED WITH mysql_native_password BY '<correct password>';

then

FLUSH PRIVILEGES;

You might still run into some more errors with getting access to the database, if you have that error run this.

GRANT ALL PRIVILEGES ON *.* to '<your-username>'@'localhost';

Well, Firefox does not support something like that.

In the reference page from Mozilla specifies font-smooth as CSS property controls the application of anti-aliasing when fonts are rendered, but this property has been removed from this specification and is currently not on the standard track.

This property is only supported in Webkit browsers.

VB Code:

Dim ListItem1 As New ListItem()
ListItem1.Text = "put anything here"
ListItem1.Value = "0"
drpTag.DataBind()
drpTag.Items.Insert(0, ListItem1)

View:

<asp:CompareValidator ID="CompareValidator1" runat="server" ErrorMessage="CompareValidator" ControlToValidate="drpTag" 
  ValueToCompare="0">
</asp:CompareValidator>

This is the simplest way you can have your own javascript function be called when an onSubmit occurs.

HTML

<form>
    <input type="text" name="name">
    <input type="submit" name="submit">
</form>

JavaScript

window.onload = function() {
    var form = document.querySelector("form");
    form.onsubmit = submitted.bind(form);
}

function submitted(event) {
    event.preventDefault();
}

If you need an ordered dictionary, you can use odict.

Just in case you guys need it, Here a couple of links that can help you:

1. download csv file from web api in angular js
2. Export javascript data to CSV file without server interaction

No this is not enough (in some specific cases)! By default PDO uses emulated prepared statements when using MySQL as a database driver. You should always disable emulated prepared statements when using MySQL and PDO:

$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

Another thing that always should be done it set the correct encoding of the database:

$dbh = new PDO('mysql:dbname=dbtest;host=127.0.0.1;charset=utf8', 'user', 'pass');

Also see this related question: How can I prevent SQL injection in PHP?

Also note that that only is about the database side of the things you would still have to watch yourself when displaying the data. E.g. by using htmlspecialchars() again with the correct encoding and quoting style.

My problem was similar but with the inconvenience that sometimes the string contains letters (sometimes empty).

string sNumbers = "1,2,hh,3,4,x,5";

Trying to follow Pcode Xonos Extension Method:

public static List<int> SplitToIntList(this string list, char separator = ',')
{
      int result = 0;
      return (from s in list.Split(',')
              let isint = int.TryParse(s, out result)
              let val = result
              where isint
              select val).ToList(); 
}

You can pass this when you call the function

<button onclick="doSomething('param',this)" id="id_button">action</button>

<script>
    function doSomething(param,me){

    var source = me
    console.log(source);
}
</script>

You may also use:

request.POST.get('section','') # => [39]
request.POST.get('MAINS','') # => [137] 
request.GET.get('section','') # => [39]
request.GET.get('MAINS','') # => [137]

Using this ensures that you don't get an error. If the POST/GET data with any key is not defined then instead of raising an exception the fallback value (second argument of .get() will be used).

Just change the line: upload_max_filesize = 50M

To check for events on an element:

var events = $._data(element, "events")

Note that this will only work with direct event handlers, if you are using $(document).on("event-name", "jq-selector", function() { //logic }), you will want to see the getEvents function at the bottom of this answer

For example:

 var events = $._data(document.getElementById("myElemId"), "events")

or

 var events = $._data($("#myElemId")[0], "events")

Full Example:

<html>
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
        <script>
            $(function() {
                $("#textDiv").click(function() {
                    //Event Handling
                });
                var events = $._data(document.getElementById('textDiv'), "events");
                var hasEvents = (events != null);
            });
        </script>
    </head>
    <body>
        <div id="textDiv">Text</div>
    </body>
</html>

A more complete way to check, that includes dynamic listeners, installed with $(document).on

function getEvents(element) {
    var elemEvents = $._data(element, "events");
    var allDocEvnts = $._data(document, "events");
    for(var evntType in allDocEvnts) {
        if(allDocEvnts.hasOwnProperty(evntType)) {
            var evts = allDocEvnts[evntType];
            for(var i = 0; i < evts.length; i++) {
                if($(element).is(evts[i].selector)) {
                    if(elemEvents == null) {
                        elemEvents = {};
                    }
                    if(!elemEvents.hasOwnProperty(evntType)) {
                        elemEvents[evntType] = [];
                    }
                    elemEvents[evntType].push(evts[i]);
                }
            }
        }
    }
    return elemEvents;
}

Example usage:

getEvents($('#myElemId')[0])

Simply Add 'carousel-item' class in place of item class.

If you prefer separation of concerns such that logic for adding and removing classes happens on the controller, you can do this

controller

 (function() {
    angular.module('MyApp', []).controller('MyController', MyController);

    function MyController() {
      var vm = this;
      vm.tab = 0;

      vm.setTab = function(val) {
          vm.tab = val;
       };
      vm.toggleClass = function(val) {
          return val === vm.tab;
           };
        }
    })();

HTML

<div ng-app="MyApp">
  <ul class="" ng-controller="MyController as myCtrl">
    <li ng-click="myCtrl.setTab(0)" ng-class="{'highlighted':myCtrl.toggleClass(0)}">One</li>
    <li ng-click="myCtrl.setTab(1)" ng-class="{'highlighted':myCtrl.toggleClass(1)}">Two</li>
    <li ng-click="myCtrl.setTab(2)" ng-class="{'highlighted':myCtrl.toggleClass(2)}">Three</li>
   <li ng-click="myCtrl.setTab(3)" ng-class="{'highlighted':myCtrl.toggleClass(3)}">Four</li>
 </ul>

CSS

.highlighted {
   background-color: green;
   color: white;

Happy coding ;)

There are some difference key notes i conclude after working on wait and sleep, first take a look on sample using wait() and sleep():

Example1: using wait() and sleep():

synchronized(HandObject) {
    while(isHandFree() == false) {
        /* Hand is still busy on happy coding or something else, please wait */
        HandObject.wait();
    }
}

/* Get lock ^^, It is my turn, take a cup beer now */
while (beerIsAvailable() == false) {
    /* Beer is still coming, not available, Hand still hold glass to get beer,
       don't release hand to perform other task */
    Thread.sleep(5000);
}

/* Enjoy my beer now ^^ */
drinkBeers();

/* I have drink enough, now hand can continue with other task: continue coding */
setHandFreeState(true);
synchronized(HandObject) {
    HandObject.notifyAll();
}

Let clarity some key notes:

1. Call on:
   • wait(): Call on current thread that hold HandObject Object
   • sleep(): Call on Thread execute task get beer (is class method so affect on current running thread)
2. Synchronized:
   • wait(): when synchronized multi thread access same Object (HandObject) (When need communication between more than one thread (thread execute coding, thread execute get beer) access on same object HandObject )
   • sleep(): when waiting condition to continue execute (Waiting beer available)
3. Hold lock:
   • wait(): release the lock for other object have chance to execute (HandObject is free, you can do other job)
   • sleep(): keep lock for at least t times (or until interrupt) (My job still not finish, i'm continue hold lock and waiting some condition to continue)
4. Wake-up condition:
   • wait(): until call notify(), notifyAll() from object
   • sleep(): until at least time expire or call interrupt
5. And the last point is use when as estani indicate:

you normally use sleep() for time-syncronization and wait() for multi-thread-synchronization.

Please correct me if i'm wrong.

In my case, I didn't import a module in a component that I was using it in.

So, just check if you are importing the module you want to use...

I have had this issue in a case where the static function was called before it was declared. Moving the function declaration to anywhere above the call solved my problem.

Here is a drop-in class that sub-classes ObservableCollection and actually raises a Reset action when a property on a list item changes. It enforces all items to implement INotifyPropertyChanged.

The benefit here is that you can data bind to this class and all of your bindings will update with changes to your item properties.

public sealed class TrulyObservableCollection<T> : ObservableCollection<T>
    where T : INotifyPropertyChanged
{
    public TrulyObservableCollection()
    {
        CollectionChanged += FullObservableCollectionCollectionChanged;
    }

    public TrulyObservableCollection(IEnumerable<T> pItems) : this()
    {
        foreach (var item in pItems)
        {
            this.Add(item);
        }
    }

    private void FullObservableCollectionCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        if (e.NewItems != null)
        {
            foreach (Object item in e.NewItems)
            {
                ((INotifyPropertyChanged)item).PropertyChanged += ItemPropertyChanged;
            }
        }
        if (e.OldItems != null)
        {
            foreach (Object item in e.OldItems)
            {
                ((INotifyPropertyChanged)item).PropertyChanged -= ItemPropertyChanged;
            }
        }
    }

    private void ItemPropertyChanged(object sender, PropertyChangedEventArgs e)
    {            
        NotifyCollectionChangedEventArgs args = new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Replace, sender, sender, IndexOf((T)sender));
        OnCollectionChanged(args);
    }
}

To complete BalusC -> ANSWER If you are using perl you can use CGI to add HTTP headers.

Using Perl:

Use CGI;    
sub set_new_query() {
        binmode STDOUT, ":utf8";
        die if defined $query;
        $query = CGI->new();
        print $query->header(
                        -expires       => 'Sat, 26 Jul 1997 05:00:00 GMT',
                        -Pragma        => 'no-cache',
                        -Cache_Control => join(', ', qw(

                                            no-store

                                            max-age=0
                                            pre-check=0
                                            post-check=0 
                                           ))
        );
    }

Using apache httpd.conf

Note: When I tried to use the html META, browsers ignored them and cached the page.

No they can't. But:

template<typename T>
class Foo {
public:
  template<typename P>
  void f(const P& p) {
    ((T*)this)->f<P>(p);
  }
};

class Bar : public Foo<Bar> {
public:
  template<typename P>
  void f(const P& p) {
    std::cout << p << std::endl;
  }
};

int main() {
  Bar bar;

  Bar *pbar = &bar;
  pbar -> f(1);

  Foo<Bar> *pfoo = &bar;
  pfoo -> f(1);
};

has much the same effect if all you want to do is have a common interface and defer implementation to subclasses.

@Harris's answer is great, I've implemented it as a separate subclass of EditText, which can make it easier to use if your code already adds TextChangedListeners.

Also, I've tweaked it so that, if you already use any Compound Drawables, it leaves them intact.

Code is here, for anyone who needs it:

package com.companyname.your

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.EditText;

public class ClearableEditText extends EditText {

    public String defaultValue = "";
    final Drawable imgX = getResources().getDrawable(android.R.drawable.presence_offline ); // X image


    public ClearableEditText(Context context) {
        super(context);

        init();
    }

    public ClearableEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

        init();
    }

    public ClearableEditText(Context context, AttributeSet attrs) {
        super(context, attrs);

        init();
    }


    void init()  {

        // Set bounds of our X button
        imgX.setBounds(0, 0, imgX.getIntrinsicWidth(), imgX.getIntrinsicHeight());      

        // There may be initial text in the field, so we may need to display the button
        manageClearButton();

        this.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                ClearableEditText et = ClearableEditText.this;

                // Is there an X showing?
                if (et.getCompoundDrawables()[2] == null) return false;
                // Only do this for up touches
                if (event.getAction() != MotionEvent.ACTION_UP) return false;
                // Is touch on our clear button?
                if (event.getX() > et.getWidth() - et.getPaddingRight() - imgX.getIntrinsicWidth()) {
                    et.setText("");
                    ClearableEditText.this.removeClearButton();
                }
                return false;
            }
        });

        this.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

                ClearableEditText.this.manageClearButton();
            }

            @Override
            public void afterTextChanged(Editable arg0) {
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }
        });
    }

    void manageClearButton() {
        if (this.getText().toString().equals("") )
            removeClearButton();
        else
            addClearButton();
    }
    void addClearButton() {
        this.setCompoundDrawables(this.getCompoundDrawables()[0], 
                this.getCompoundDrawables()[1],
                imgX,
                this.getCompoundDrawables()[3]);
    }
    void removeClearButton() {
        this.setCompoundDrawables(this.getCompoundDrawables()[0], 
                this.getCompoundDrawables()[1],
                null,
                this.getCompoundDrawables()[3]);
    }

}

This may not be relevant to your specific issue, but I had a similar problem when the pickle archive had been created using gzip.

For example if a compressed pickle archive is made like this,

import gzip, pickle
with gzip.open('test.pklz', 'wb') as ofp:
    pickle.dump([1,2,3], ofp)

Trying to open it throws the errors

 with open('test.pklz', 'rb') as ifp:
     print(pickle.load(ifp))
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
_pickle.UnpicklingError: invalid load key, ''.

But, if the pickle file is opened using gzip all is harmonious

with gzip.open('test.pklz', 'rb') as ifp:
    print(pickle.load(ifp))

[1, 2, 3]

Found the problem and couldn't find the solution until tried this.

1. Open Visual Basic from Developer tab (OR right-click at any sheet and click 'View code')
2. At upper left panel, select 'ThisWorkbook'
3. At lower left panel, find 'ForceFullCalculation' attribute
4. Change it from 'False' to 'True' and save it

I'm not sure if this has any side-effect, but it is work for me now.

I had the same problem. I want a 100% transparent background color. Just use this code; it's worked great for me:

rgba(54, 25, 25, .00004);

You can see examples on the left side on this web page (the contact form area).

This message digital envelope routines: EVP_DecryptFInal_ex: bad decrypt can also occur when you encrypt and decrypt with an incompatible versions of openssl.

The issue I was having was that I was encrypting on Windows which had version 1.1.0 and then decrypting on a generic Linux system which had 1.0.2g.

It is not a very helpful error message!

Working solution:

A possible solution from @AndrewSavinykh that worked for many (see the comments):

Default digest has changed between those versions from md5 to sha256. One can specify the default digest on the command line as -md sha256 or -md md5 respectively

A little bit late to the party... but I found this as a solution for me when having "blocked"-Error in chrome:

Blocking resources whose URLs contain both \n and < characters.

As answered by Magus :

the full path must me specified

Abstract states can be used to add a prefix to all child state urls. But note that abstract still needs a ui-view for its children to populate. To do so you can simply add it inline.

.state('app', {
   url: "/app",
   abstract: true,
   template: '<ui-view/>'
})

For more information see documentation : https://github.com/angular-ui/ui-router/wiki/Nested-States-%26-Nested-Views

Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)

Do it the other way around:

$a = "1,435";
$b = str_replace( ',', '', $a );

if( is_numeric( $b ) ) {
    $a = $b;
}

The easiest would be:

$var = intval(preg_replace('/[^\d.]/', '', $var));

or if you need float:

$var = floatval(preg_replace('/[^\d.]/', '', $var));

An IntentService is an extension of a Service that is made to ease the execution of a task that needs to be executed in background and in a seperated thread.

IntentService starts, create a thread and runs its task in the thread. once done, it cleans everything. Only one instance of a IntentService can run at the same time, several calls are enqueued.

It is very simple to use and very convenient for a lot of uses, for instance downloading stuff. But it has limitations that can make you want to use instead the more basic (not simple) Service.

For example, a service connected to a xmpp server and bound by activities cannot be simply done using an IntentService. You'll end up ignoring or overriding IntentService stuffs.

Use FROM_UNIXTIME().

Note: 1299762201428 looks more like a millisecond-timestamp (like Date()*1 in JavaScript), and you probably have to divide that by 1000.

You're simply after the Array.Exists function (or the Contains extension method if you're using .NET 3.5, which is slightly more convenient).

Note that HTTP doesn't typically keep TCP connections open for any longer than it takes to transmit the page to the client; and it usually takes much more time for the user to read a web page than it takes to download the page... while the user is viewing the page, he adds no load to the server at all.

So the number of people that can be simultaneously viewing your web site is much larger than the number of TCP connections that it can simultaneously serve.

There is a much easier way to run Java, no configuration needed:

1. Install the Code Runner Extension
2. Open your Java code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.

I've had the problem which was two pronged:
1. In a form with multiple select2 elements, the dropdown won't open on tab, and you need to press space key to open it
2. Once you have made a selection, the tabindex won't be honored and you have to manually click on the next input field

While the usual suggestions worked, I came up with my own version, since a library script was doing the conversion of normal select to select2, and hence I had no control over this initialization.

Here is the code that worked for me.

Tab to open

$(document).on("focus", ".select2", function() {
    $(this).siblings("select").select2("open");
});

Move to next on selection

var inputs = $("input,select"); // You can use other elements such as textarea, button etc. 
                                //depending on input field types you have used
$("select").on("select2:close",function(){
    var pos = $(inputs).index(this) + 1;
    var next = $(inputs).eq(pos);
    setTimeout( function() {
        next.focus();
        if (next.siblings(".select2").length) { //If it's a select
            next.select2("open");
        }
    }, 500); //The delay is required to allow default events to occur
});

Hope this helps.
