SQL Server does not track the order of inserted rows, so there is no reliable way to get that information given your current table structure. Even if employee_id is an IDENTITY column, it is not 100% foolproof to rely on that for order of insertion (since you can fill gaps and even create duplicate ID values using SET IDENTITY_INSERT ON). If employee_id is an IDENTITY column and you are sure that rows aren't manually inserted out of order, you should be able to use this variation of your query to select the data in sequence, newest first:

SELECT 
   ROW_NUMBER() OVER (ORDER BY EMPLOYEE_ID DESC) AS ID, 
   EMPLOYEE_ID,
   EMPLOYEE_NAME 
FROM dbo.CSBCA1_5_FPCIC_2012_EES207201222743
ORDER BY ID;

You can make a change to your table to track this information for new rows, but you won't be able to derive it for your existing data (they will all me marked as inserted at the time you make this change).

ALTER TABLE dbo.CSBCA1_5_FPCIC_2012_EES207201222743 
-- wow, who named this?
  ADD CreatedDate DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP;

Note that this may break existing code that just does INSERT INTO dbo.whatever SELECT/VALUES() - e.g. you may have to revisit your code and define a proper, explicit column list.

From the Oracle docs

ROWID Pseudocolumn

For each row in the database, the ROWID pseudocolumn returns the address of the row. Oracle Database rowid values contain information necessary to locate a row:

• The data object number of the object
• The data block in the datafile in which the row resides
• The position of the row in the data block (first row is 0)
• The datafile in which the row resides (first file is 1). The file number is relative to the tablespace.

The closest equivalent to this in SQL Server is the rid which has three components File:Page:Slot.

In SQL Server 2008 it is possible to use the undocumented and unsupported %%physloc%% virtual column to see this. This returns a binary(8) value with the Page ID in the first four bytes, then 2 bytes for File ID, followed by 2 bytes for the slot location on the page.

The scalar function sys.fn_PhysLocFormatter or the sys.fn_PhysLocCracker TVF can be used to convert this into a more readable form

CREATE TABLE T(X INT);

INSERT INTO T VALUES(1),(2)

SELECT %%physloc%% AS [%%physloc%%],
       sys.fn_PhysLocFormatter(%%physloc%%) AS [File:Page:Slot]
FROM T

Example Output

+--------------------+----------------+
|    %%physloc%%     | File:Page:Slot |
+--------------------+----------------+
| 0x2926020001000000 | (1:140841:0)   |
| 0x2926020001000100 | (1:140841:1)   |
+--------------------+----------------+

Note that this is not leveraged by the query processor. Whilst it is possible to use this in a WHERE clause

SELECT *
FROM T
WHERE %%physloc%% = 0x2926020001000100 

SQL Server will not directly seek to the specified row. Instead it will do a full table scan, evaluate %%physloc%% for each row and return the one that matches (if any do).

To reverse the process carried out by the 2 previously mentioned functions and get the binary(8) value corresponding to known File,Page,Slot values the below can be used.

DECLARE @FileId int = 1,
        @PageId int = 338,
        @Slot   int = 3

SELECT CAST(REVERSE(CAST(@PageId AS BINARY(4))) AS BINARY(4)) +
       CAST(REVERSE(CAST(@FileId AS BINARY(2))) AS BINARY(2)) +
       CAST(REVERSE(CAST(@Slot   AS BINARY(2))) AS BINARY(2))

Config file:

worker_processes  4;  # 2 * Number of CPUs

events {
    worker_connections  19000;  # It's the key to high performance - have a lot of connections available
}

worker_rlimit_nofile    20000;  # Each connection needs a filehandle (or 2 if you are proxying)


# Total amount of users you can serve = worker_processes * worker_connections

Jquery approach mentioned on the top will work. You can also use JQuery and CSS .Say for e.g on Div one you have applied class1 and div2 you have applied class class2 (say for e.g each class of css provides specific position on the browser), now you can interchange the classes use jquery or javascript (that will change the position)

Instead of assuming the difference coding I did something like this, as I dint had menu options in my application.

final View root= findViewById(R.id.myrootview); 
root.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
    public void onGlobalLayout() {
        int heightDiff = root.getRootView().getHeight() - root.getHeight();

        Rect rectgle= new Rect();
        Window window= getWindow();
        window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
        int contentViewTop=                     
          window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
        if(heightDiff <= contentViewTop){
            //Soft KeyBoard Hidden
        }else{
            //Soft KeyBoard Shown
        }
     }
});

can be done with the plugin: https://wiki.jenkins-ci.org/display/JENKINS/Next+Build+Number+Plugin

more info: http://www.alexlea.me/2010/10/howto-set-hudson-next-build-number.html

if you don't like the plugin:

If you want to change build number via nextBuildNumber file you should "Reload Configuration from Disk" from "Manage Jenkins" page.

If you think about the performace ,may be you can use "PERFORM" in a function just like this:

 PERFORM 1 FROM skytf.test_2 WHERE id=i LIMIT 1;
  IF FOUND THEN
      RAISE NOTICE ' found record id=%', i;  
  ELSE
      RAISE NOTICE ' not found record id=%', i;  
 END IF;

In you want to know the data from de selected row, you can try this snippet code:

DataGridView1.SelectedRows.Item(0).Cells(1).Value

The setReadOnly(state) is very useful for forms, we can set any field to setReadOnly(state) directly or from various condition.But I prefer to use readOnly for setting opacity to the selector otherwise the attr='disabled' also worked like the same way.

readOnly examples:

$('input').setReadOnly(true);

or through the various codition like

var same = this.checked;
$('input').setReadOnly(same);

here we are using the state boolean value to set and remove readonly attribute from the input depending on a checkbox click.

Runtime runtime = Runtime.getRuntime();
try {
    Process p1 = runtime.exec("cmd /c start D:\\temp\\a.bat");
    InputStream is = p1.getInputStream();
    int i = 0;
    while( (i = is.read() ) != -1) {
        System.out.print((char)i);
    }
} catch(IOException ioException) {
    System.out.println(ioException.getMessage() );
}

I think it may be worth mentioning that [ConditionalAttribute] is in the System.Diagnostics; namespace. I stumbled a bit when I got:

Error 2 The type or namespace name 'ConditionalAttribute' could not be found (are you missing a using directive or an assembly reference?)

after using it for the first time (I thought it would have been in System).

import re
ipv=raw_input("Enter an ip address")
a=ipv.split('.')
s=str(bin(int(a[0]))+bin(int(a[1]))+bin(int(a[2]))+bin(int(a[3])))
s=s.replace("0b",".")
m=re.search('\.[0,1]{1,8}\.[0,1]{1,8}\.[0,1]{1,8}\.[0,1]{1,8}$',s)
if m is not None:
    print "Valid sequence of input"
else :
    print "Invalid input sequence"

Just to keep it simple I have used this approach. Simple as in to explain how really ipv4 address is evaluated. Checking whether its a binary number is although not required. Hope you like this.

MimeTypeMap.getSingleton().getExtensionFromMimeType(file.getName());

Probably, this is the easiest solution.

https://developer.android.com/reference/android/webkit/MimeTypeMap

https://developer.android.com/reference/java/net/URLConnection.html#guessContentTypeFromName(java.lang.String)

private void openFile(File file) {

    Uri uri = Uri.fromFile(file);

    Intent intent = new Intent(Intent.ACTION_VIEW);

    intent.setDataAndType(uri, MimeTypeMap.getSingleton().getExtensionFromMimeType(file.getName()));


    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(Intent.createChooser(intent, "Open " + file.getName() + " with ..."));
}

If you want to use a class:

from datetime import datetime,timedelta

class MyThread(): 

    def __init__(self, name, timeLimit):        
        self.name = name
        self.timeLimit = timeLimit
    def run(self): 
        # get the start time
        startTime = datetime.now()
    
        while True:
           # stop if the time limit is reached :
           if((datetime.now()-startTime)>self.timeLimit):
               break
           print('A')

mt = MyThread('aThread',timedelta(microseconds=20000))
mt.run()

I know this post is closed but I think my way could help some people. So there it is :

My dataset is very similar but is a bit more complex. It has numbers, alphanumeric data :

1
2
Chair 
3
0
4
5
-
Table
10
13
19
Windows
99
102
Dog

I would like to have the '-' symbol at first, then the numbers, then the text.

So I go like this :

SELECT name, (name = '-') boolDash, (name = '0') boolZero, (name+0 > 0) boolNum 
FROM table 
ORDER BY boolDash DESC, boolZero DESC, boolNum DESC, (name+0), name

The result should be something :

-
0    
1
2
3
4
5
10
13
99
102
Chair
Dog
Table
Windows

The whole idea is doing some simple check into the SELECT and sorting with the result.

Simply check it by calling post method on your layout or view

 view.post( new Runnable() {
     @Override
     public void run() {
        // your layout is now drawn completely , use it here.
      }
});

Try installing it again with the stand alone installer https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager-end-user-license-agreement - assuming you have a CPU that supports Virtualization, have turned off antivirus and any hypervisor.

Just adding to Jason's answer, the . selector is only for classes. If you want to select something other than the element, id, or class, you need to wrap it in square brackets.

e.g.

$('element[attr=val]')

This constructor was deprecated in API level 26.1.0. use NotificationCompat.Builder(Context, String) instead. All posted Notifications must specify a NotificationChannel Id.

It is also possible to receive this error from a select component if the query fails in an unusual manner (eg: a sub-query returns multiple rows in an oracle oledb connection)

SELECT array_to_string(array(SELECT a FROM b),', ');

Will do as well.

Add 0.001 first to the number and then call setScale(2, RoundingMode.ROUND_HALF_UP)

Code example:

public static void main(String[] args) {
    BigDecimal a = new BigDecimal("10.12445").add(new BigDecimal("0.001"));
    BigDecimal b = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println(b);
}

First, Latin-1 is the same as ISO-8859-1, so, the default was already OK for you. Right?

You successfully set the encoding to ISO-8859-1 with your command line parameter. You also set it programmatically to "Latin-1", but, that's not a recognized value of a file encoding for Java. See http://java.sun.com/javase/6/docs/technotes/guides/intl/encoding.doc.html

When you do that, looks like Charset resets to UTF-8, from looking at the source. That at least explains most of the behavior.

I don't know why OutputStreamWriter shows ISO8859_1. It delegates to closed-source sun.misc.* classes. I'm guessing it isn't quite dealing with encoding via the same mechanism, which is weird.

But of course you should always be specifying what encoding you mean in this code. I'd never rely on the platform default.

You can do both in one query using the OVER clause on another COUNT

select
    count(*) RecordsPerGroup,
    COUNT(*) OVER () AS TotalRecords
from temptable
group by column_1, column_2, column_3, column_4

The code I use with jQuery:

$("a.btn_external").click(function() {
    url_to_open = $(this).attr("href");
    window.open(url_to_open, '_blank');
    return false;
});

This is useful to distinguish between the click events of a parent in a child. By using this method, you do not trigger the parent's click event.

Once gdb starts, you can run the program using "r args".

So if you are running your code by:

$ executablefile arg1 arg2 arg3 

Debug it on gdb by:

$ gdb executablefile  
(gdb) r arg1 arg2 arg3

In my case it happens when introducing host with templates, graphs,trigger etc, the server falls. The problem was that by default the cache is at 128k and you have to change it.

sudo nano /etc/zabbix/zabbix-server.conf

Uncheck # Sizecache and add 32M for example.

Cachesize=32M

restart service and voila!! server working

service zabbix-server start

There is no portable way to get resolution of less than a second in standard C So best you can do is, use the POSIX function gettimeofday().

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

You would like to add column z to the old data frame (old.df) defined by columns x and y.

z = rbinom(1000, 5, 0.25)
old.df <- data.frame(x = c(1:1000), y = rnorm(1:1000))
head(old.df)

Define a new data frame called new.df

new.df <- data.frame(x = old.df[,1], z, y = old.df[,2])
head(new.df)

The DataSet object has a Tables array. If you know the table you want, it will have a Row array, each object of which has an ItemArray array. In your case the code would most likely be

int var1 = int.Parse(ds.Tables[0].Rows[0].ItemArray[4].ToString());

and so forth. This would give you the 4th item in the first row. You can also use Columns instead of ItemArray and specify the column name as a string instead of remembering it's index. That approach can be easier to keep up with if the table structure changes. So that would be

int var1 = int.Parse(ds.Tables[0].Rows[0]["MyColumnName"].ToString());

What happens, if you do this way:-

$('#new_user_form input, #new_user_form select').each(function(key, value) {

This method would work for a list implementation and could be implemented as an extension method.

public void TestMethod()
{
    var first = new List<int> {1, 2, 3, 4, 5};
    var second = new List<string> {"One", "Two", "Three", "Four", "Five"};

    foreach(var value in this.Zip(first, second, (x, y) => new {Number = x, Text = y}))
    {
        Console.WriteLine("{0} - {1}",value.Number, value.Text);
    }
}

public IEnumerable<TResult> Zip<TFirst, TSecond, TResult>(List<TFirst> first, List<TSecond> second, Func<TFirst, TSecond, TResult> selector)
{
    if (first.Count != second.Count)
        throw new Exception();  

    for(var i = 0; i < first.Count; i++)
    {
        yield return selector.Invoke(first[i], second[i]);
    }
}

How about:

mySwitchFunction = (param) => {
   switch (param) {
      case 'A':
         return ([
            <div />,
         ]);
      // etc...
   }
}
render() {
    return (
       <div>
          <div>
               // removed for brevity
          </div>

          { this.mySwitchFunction(param) }

          <div>
              // removed for brevity
          </div>
      </div>
   );
}

Its not ideal but you can use a proxy server and it works fine. For example go to hidemyass.com put in www.google.com and put the link it goes to in an iframe and it works!

Use this simple function for date comparison

-(BOOL)dateComparision:(NSDate*)date1 andDate2:(NSDate*)date2{

BOOL isTokonValid;

if ([date1 compare:date2] == NSOrderedDescending) {
    NSLog(@"date1 is later than date2");
    isTokonValid = YES;
} else if ([date1 compare:date2] == NSOrderedAscending) {
    NSLog(@"date1 is earlier than date2");
    isTokonValid = NO;
} else {
    isTokonValid = NO;
    NSLog(@"dates are the same");
}

return isTokonValid;}

You can use DataFrame.xs():

In [36]: df = DataFrame(np.random.randn(10, 4))

In [37]: df.columns = [np.random.choice(['a', 'b'], size=4).tolist(), np.random.choice(['c', 'd'], size=4)]

In [38]: df.columns.names = ['A', 'B']

In [39]: df

7  0.139  0.851
8 -1.534  0.534
9 -1.885 -1.543

If you want to keep the A level (the drop_level keyword argument is only available starting from v0.13.0):

In [42]: df.xs('a', level='A', axis=1, drop_level=False)
Out[42]:
A      a

Assuming a simple case, where your field is public:

List list; // from your method
for(Object x : list) {
    Class<?> clazz = x.getClass();
    Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
    Object fieldValue = field.get(x);
}

But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).

If you can change your method to return a List<Foo>, this becomes very easy because the iterator then can give you type information:

List<Foo> list; //From your method
for(Foo foo:list) {
    Object fieldValue = foo.fieldName;
}

Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...

List list;
for(Object x: list) {
   if( x instanceof Foo) {
      Object fieldValue = ((Foo)x).fieldName;
   }
}

No reflection needed :)

If you want to split the string, it's best to use:

$array = str_split($string);

When you have delimiter, which separates the string, you can try,

explode('' ,$string);

Where you can pass the delimiter in the first variable inside the explode such as:

explode(',',$string);

The problem is you are setting the window.location.hash to an element's ID attribute. It is the expected behavior for the browser to jump to that element, regardless of whether you "preventDefault()" or not.

One way to get around this is to prefix the hash with an arbitrary value like so:

window.location.hash = 'panel-' + id.replace('#', '');

Then, all you need to do is to check for the prefixed hash on page load. As an added bonus, you can even smooth scroll to it since you are now in control of the hash value...

$(function(){
    var h = window.location.hash.replace('panel-', '');
    if (h) {
        $('#slider').scrollTo(h, 800);
    }
});

If you need this to work at all times (and not just on the initial page load), you can use a function to monitor changes to the hash value and jump to the correct element on-the-fly:

var foundHash;
setInterval(function() {
    var h = window.location.hash.replace('panel-', '');
    if (h && h !== foundHash) {
        $('#slider').scrollTo(h, 800);
        foundHash = h;
    }
}, 100);

There is a nuance to updating tables then updating the DBML... Foreign key relationships are not immediately always brought over if changes are made to existing tables. The work around is to do a build of the project and then re-add the tables again. I reported this to MS and its being fixed for VS2010.

DBML display does not show new foreign key constraints

Note that the instructions given in the main answer are not clear. To update the table

1. Open up the dbml design surface
2. Select all tables with Right->Click->Select All or CTRLa
3. CTRLx (Cut)
4. CTRLv (Paste)
5. Save and rebuild solution.

mystring.eql? yourstring

Are equivalent.

I had this problem when using Butterknife library. I had:

View rootView = inflater.inflate
                (R.layout.fragment_recipe_detail_view, container, false);
ButterKnife.bind(rootView);

But the correct version is:

View rootView = inflater.inflate
                (R.layout.fragment_recipe_detail_view, container, false);
ButterKnife.bind(this, rootView);

This error occurs because of missing some files and the main reason is "Composer"

First Run these commands in CMD

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'e0012edf3e80b6978849f5eff0d4b4e4c79ff1609dd1e613307e16318854d24ae64f26d17af3ef0bf7cfb710ca74755a') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

Then Create a New project
Example:

D:/Laravel_Projects/New_Project
laravel new New_Project

After that start the server using

php artisan serve

mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There's a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example.

Ubuntu, for example, has MinGW in its repositories:

$ apt-cache search mingw
[...]
g++-mingw-w64 - GNU C++ compiler for MinGW-w64
gcc-mingw-w64 - GNU C compiler for MinGW-w64
mingw-w64 - Development environment targeting 32- and 64-bit Windows
[...]

Use eval.

There are several possibilities:

1- The first one is the use of the MediaQuery :

Code :

MediaQuery.of(context).size.width //to get the width of screen
MediaQuery.of(context).size.height //to get height of screen

Example of use :

Container(
        color: Colors.yellow,
        height: MediaQuery.of(context).size.height * 0.65,
        width: MediaQuery.of(context).size.width,
      )

Output :

2- The use of FractionallySizedBox

Creates a widget that sizes its child to a fraction of the total available space.

Example :

FractionallySizedBox(
           widthFactor: 0.65, // between 0 and 1 
           heightFactor: 1.0,
           child:Container(color: Colors.red
           ,),
         )

Output :

3- The use of other widgets such as Expanded , Flexible and AspectRatio and more .

you can remove an App from the store or "Unpublish" by clicking a tiny label bellow your app's title, right side of the "PUBLISHED" green status label.

Works even if your app was live (published) for long time, mine was.

Regards.

option-1:

edit \My Documents\IISExpress\config\applicationhost.config file and enable windowsAuthentication, i.e:

<system.webServer>
...
  <security>
...
    <authentication>
      <windowsAuthentication enabled="true" />
    </authentication>
...
  </security>
...
</system.webServer>

option-2:

Unlock windowsAuthentication section in \My Documents\IISExpress\config\applicationhost.config as follows

<add name="WindowsAuthenticationModule" lockItem="false" />

Alter override settings for the required authentication types to 'Allow'

<sectionGroup name="security">
    ...
    <sectionGroup name="system.webServer">
        ...
        <sectionGroup name="authentication">
            <section name="anonymousAuthentication" overrideModeDefault="Allow" />
            ...
            <section name="windowsAuthentication" overrideModeDefault="Allow" />
    </sectionGroup>
</sectionGroup>

Add following in the application's web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
      <security>
        <authentication>
          <windowsAuthentication enabled="true" />
        </authentication>
      </security>
    </system.webServer>
</configuration>

Below link may help: http://learn.iis.net/page.aspx/376/delegating-configuration-to-webconfig-files/

After installing VS 2010 SP1 applying option 1 + 2 may be required to get windows authentication working. In addition, you may need to set anonymous authentication to false in IIS Express applicationhost.config:

<authentication>

            <anonymousAuthentication enabled="false" userName="" />

for VS2015, the IIS Express applicationhost config file may be located here:

$(solutionDir)\.vs\config\applicationhost.config

and the <UseGlobalApplicationHostFile> option in the project file selects the default or solution-specific config file.

All the answer are showing how to do it with class components, but for functional components you do:

const MyComponent = () => {
    return (
        <SafeAreaView>
            <Text>MyComponent</Text>
        </SafeAreaView>
    )
}

MyComponent.navigationOptions = ({ /*navigation*/ }) => {
    return {
        header: null
    }
}

If you remove the header your component may be on places where you can't see it (when the phone don't have square screen) so it's important to use it when removing the header.

These examples seem a bit inefficient. Try this if you want to act upon the value:

<input id="cta" type="email" placeholder="Enter Email...">
<button onclick="return joinMailingList()">Join</button>

<script>
    const joinMailingList = () => {
        const email = document.querySelector('#cta').value
        console.log(email)
    }
</script>

You will encounter issue if you use this keyword with fat arrow (=>). If you need to do that, go old school:

<script>
    function joinMailingList() {
        const email = document.querySelector('#cta').value
        console.log(email)
    }
</script>

If you are working with password inputs, you should use type="password" so it will display ****** while the user is typing, and it is also more semantic.

For t-SQL I use the following query for varchar columns (shows the collation and is_null properties):

SELECT
    s.name
    , o.name as table_name
    , c.name as column_name
    , t.name as type
    , c.max_length
    , c.collation_name
    , c.is_nullable
FROM
    sys.columns c
    INNER JOIN sys.objects o ON (o.object_id = c.object_id)
    INNER JOIN sys.schemas s ON (s.schema_id = o.schema_id)
    INNER JOIN sys.types t ON (t.user_type_id = c.user_type_id)
WHERE
    s.name = 'dbo'
    AND t.name IN ('varchar') -- , 'char', 'nvarchar', 'nchar')
ORDER BY
    o.name, c.name

To apply it everywhere, you could do something like

$('body').on('click', function() {
   if($('.children').is(':visible')) {
      $('ul.children').slideUp('slow');
   }
});

If the class does not have toString() method, then you can use ToStringBuilder class from org.apache.commons:commons-lang3

pom.xml:

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.10</version>
</dependency>

code:

ToStringBuilder.reflectionToString(yourObject)

change user to root

sodu su -

browse to etc

vi sudoers

look for root user in user priviledge section. you will get it like

root ALL=(ALL:ALL) ALL 

make same entry for your user name. if you username is 'myuser' then add

myuser ALL=(ALL:ALL) ALL

it will look like

root ALL=(ALL:ALL) ALL 

myuser ALL=(ALL:ALL) ALL 

save it. change root user to your user. now try the same where you were getting the sudoers issue

    final String cookiePath = "/";

    Cookie cookie = new Cookie(cookieName, cookieValue);

    cookie.setSecure(useSecureCookie);  // determines whether the cookie should only be sent using a secure protocol, such as HTTPS or SSL

    cookie.setMaxAge(expiryTime);  // A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

    cookie.setPath(cookiePath);  // The cookie is visible to all the pages in the directory you specify, and all the pages in that directory's subdirectories

    response.addCookie(cookie);

It may be a little late for this question to be answered, but here is what I found.

I don't want to debate on the fact that nodes does that better than php or not, this is not the point.

The solution is : I haven't found any implementation of socket.io for PHP.

But there are some ways to implement WebSockets. There is this jQuery plugin allowing you to use Websockets while gracefully degrading for non-supporting browsers. On the PHP side, there is this class which seems to be the most widely used for PHP WS servers.

If you are using the background image for the rounded corners then I would rather increase the padding style of the main div to give enough room for the rounded corners of the background image to be visible.

Try increasing the padding of the main div style:

#mainWrapperDivWithBGImage 
{   
    background: url("myImageWithRoundedCorners.jpg") no-repeat scroll 0 0 transparent;   
    height: 248px;   
    margin: 0;   
    overflow: hidden;   
    padding: 10px 10px;   
    width: 996px; 
}

P.S: I assume the rounded corners have a radius of 10px.

I've just used Deferred in real code. In project jQuery Terminal I have function exec that call commands defined by user (like he was entering it and pressing enter), I've added Deferreds to the API and call exec with arrays. like this:

terminal.exec('command').then(function() {
   terminal.echo('command finished');
});

or

terminal.exec(['command 1', 'command 2', 'command 3']).then(function() {
   terminal.echo('all commands finished');
});

the commands can run async code, and exec need to call user code in order. My first api use pair of pause/resume calls and in new API I call those automatic when user return promise. So user code can just use

return $.get('/some/url');

or

var d = new $.Deferred();
setTimeout(function() {
    d.resolve("Hello Deferred"); // resolve value will be echoed
}, 500);
return d.promise();

I use code like this:

exec: function(command, silent, deferred) {
    var d;
    if ($.isArray(command)) {
        return $.when.apply($, $.map(command, function(command) {
            return self.exec(command, silent);
        }));
    }
    // both commands executed here (resume will call Term::exec)
    if (paused) {
        // delay command multiple time
        d = deferred || new $.Deferred();
        dalyed_commands.push([command, silent, d]);
        return d.promise();
    } else {
        // commands may return promise from user code
        // it will resolve exec promise when user promise
        // is resolved
        var ret = commands(command, silent, true, deferred);
        if (!ret) {
            if (deferred) {
                deferred.resolve(self);
                return deferred.promise();
            } else {
                d = new $.Deferred();
                ret = d.promise();
                ret.resolve();
            }
        }
        return ret;
    }
},

dalyed_commands is used in resume function that call exec again with all dalyed_commands.

and part of the commands function (I've stripped not related parts)

function commands(command, silent, exec, deferred) {

    var position = lines.length-1;
    // Call user interpreter function
    var result = interpreter.interpreter(command, self);
    // user code can return a promise
    if (result != undefined) {
        // new API - auto pause/resume when using promises
        self.pause();
        return $.when(result).then(function(result) {
            // don't echo result if user echo something
            if (result && position === lines.length-1) {
                display_object(result);
            }
            // resolve promise from exec. This will fire
            // code if used terminal::exec('command').then
            if (deferred) {
                deferred.resolve();
            }
            self.resume();
        });
    }
    // this is old API
    // if command call pause - wait until resume
    if (paused) {
        self.bind('resume.command', function() {
            // exec with resume/pause in user code
            if (deferred) {
                deferred.resolve();
            }
            self.unbind('resume.command');
        });
    } else {
        // this should not happen
        if (deferred) {
            deferred.resolve();
        }
    }
}

Former, of course. Latter is redundant, and only goes to show that you haven't understood the concept of booleans very well.

One more suggestion: Choose a different name for your boolean variable. As per this Java style guide:

is prefix should be used for boolean variables and methods.

isSet, isVisible, isFinished, isFound, isOpen

This is the naming convention for boolean methods and variables used by Sun for the Java core packages.

Using the is prefix solves a common problem of choosing bad boolean names like status or flag. isStatus or isFlag simply doesn't fit, and the programmer is forced to chose more meaningful names.

Setter methods for boolean variables must have set prefix as in:

void setFound(boolean isFound);

There are a few alternatives to the is prefix that fits better in some situations. These are has, can and should prefixes:

boolean hasLicense();
boolean canEvaluate();
boolean shouldAbort = false;

I need to detect rotation while using the camera with AVFoundation, and found that the didRotate (now deprecated) & willTransition methods were unreliable for my needs. Using the notification posted by David did work, but is not current for Swift 3.x & above.

The following makes use of a closure, which appears to be Apple's preference going forward.

var didRotate: (Notification) -> Void = { notification in
        switch UIDevice.current.orientation {
        case .landscapeLeft, .landscapeRight:
            print("landscape")
        case .portrait, .portraitUpsideDown:
            print("Portrait")
        default:
            print("other (such as face up & down)")
        }
    }

To set up the notification:

NotificationCenter.default.addObserver(forName: UIDevice.orientationDidChangeNotification,
                                       object: nil,
                                       queue: .main,
                                       using: didRotate)

To tear down the notification:

NotificationCenter.default.removeObserver(self,
                                          name: UIDevice.orientationDidChangeNotification,
                                          object: nil)

Regarding the deprecation statement, my initial comment was misleading, so I wanted to update that. As noted, the usage of @objc inference has been deprecated, which in turn was needed to use a #selector. By using a closure instead, this can be avoided and you now have a solution that should avoid a crash due to calling an invalid selector.

Might be a little late but for new issues like this I use this code:

moment(timestamp, 'X').format('lll');

You can change the format to match your needs and also add timezone like this:

moment(timestamp, 'X').tz(timezone).format('lll');

Any searching with select statement yield you only object name, where search keyword contains. Easiest and efficient way is get script of procedure/function and then search in generated text file, I also follows this technique :) So you are exact pinpoint.

A combination of line styles, markers, and qualitative colors from matplotlib:

import itertools
import matplotlib as mpl
import matplotlib.pyplot as plt
N = 8*4+10
l_styles = ['-','--','-.',':']
m_styles = ['','.','o','^','*']
colormap = mpl.cm.Dark2.colors   # Qualitative colormap
for i,(marker,linestyle,color) in zip(range(N),itertools.product(m_styles,l_styles, colormap)):
    plt.plot([0,1,2],[0,2*i,2*i], color=color, linestyle=linestyle,marker=marker,label=i)
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=4);

UPDATE: Supporting not only ListedColormap, but also LinearSegmentedColormap

import itertools
import matplotlib.pyplot as plt
Ncolors = 8
#colormap = plt.cm.Dark2# ListedColormap
colormap = plt.cm.viridis# LinearSegmentedColormap
Ncolors = min(colormap.N,Ncolors)
mapcolors = [colormap(int(x*colormap.N/Ncolors)) for x in range(Ncolors)]
N = Ncolors*4+10
l_styles = ['-','--','-.',':']
m_styles = ['','.','o','^','*']
fig,ax = plt.subplots(gridspec_kw=dict(right=0.6))
for i,(marker,linestyle,color) in zip(range(N),itertools.product(m_styles,l_styles, mapcolors)):
    ax.plot([0,1,2],[0,2*i,2*i], color=color, linestyle=linestyle,marker=marker,label=i)
ax.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=3,prop={'size': 8})

Python is strongly, dynamically typed.

• Strong typing means that the type of a value doesn't change in unexpected ways. A string containing only digits doesn't magically become a number, as may happen in Perl. Every change of type requires an explicit conversion.
• Dynamic typing means that runtime objects (values) have a type, as opposed to static typing where variables have a type.

As for your example

bob = 1
bob = "bob"

This works because the variable does not have a type; it can name any object. After bob=1, you'll find that type(bob) returns int, but after bob="bob", it returns str. (Note that type is a regular function, so it evaluates its argument, then returns the type of the value.)

Contrast this with older dialects of C, which were weakly, statically typed, so that pointers and integers were pretty much interchangeable. (Modern ISO C requires conversions in many cases, but my compiler is still lenient about this by default.)

I must add that the strong vs. weak typing is more of a continuum than a boolean choice. C++ has stronger typing than C (more conversions required), but the type system can be subverted by using pointer casts.

The strength of the type system in a dynamic language such as Python is really determined by how its primitives and library functions respond to different types. E.g., + is overloaded so that it works on two numbers or two strings, but not a string and an number. This is a design choice made when + was implemented, but not really a necessity following from the language's semantics. In fact, when you overload + on a custom type, you can make it implicitly convert anything to a number:

def to_number(x):
    """Try to convert function argument to float-type object."""
    try: 
        return float(x) 
    except (TypeError, ValueError): 
        return 0 

class Foo:
    def __init__(self, number): 
        self.number = number

    def __add__(self, other):
        return self.number + to_number(other)

Instance of class Foo can be added to other objects:

>>> a = Foo(42)
>>> a + "1"
43.0
>>> a + Foo
42
>>> a + 1
43.0
>>> a + None
42

Observe that even though strongly typed Python is completely fine with adding objects of type int and float and returns an object of type float (e.g., int(42) + float(1) returns 43.0). On the other hand, due to the mismatch between types Haskell would complain if one tries the following (42 :: Integer) + (1 :: Float). This makes Haskell a strictly typed language, where types are entirely disjoint and only a controlled form of overloading is possible via type classes.

That is how you define an anonymous function that gets called when the document is ready.

Try connecting without any password:

mysql -u root

I believe the initial default is no password for the root account (which should obviously be changed as soon as possible).

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

Record Count From Table One
---------------------------
            0

Assuming you have two Date objects, you can just subtract them to get the difference in milliseconds:

var difference = date2 - date1;

From there, you can use simple arithmetic to derive the other values.

If your rotation angles are fairly uniform, you can use CSS:

<img id="image_canv" src="/image.png" class="rotate90">

CSS:

.rotate90 {
    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -o-transform: rotate(90deg);
    -ms-transform: rotate(90deg);
    transform: rotate(90deg);
}

Otherwise, you can do this by setting a data attribute in your HTML, then using Javascript to add the necessary styling:

<img id="image_canv" src="/image.png" data-rotate="90">

Sample jQuery:

$('img').each(function() {
    var deg = $(this).data('rotate') || 0;
    var rotate = 'rotate(' + deg + 'deg)';
    $(this).css({ 
        '-webkit-transform': rotate,
        '-moz-transform': rotate,
        '-o-transform': rotate,
        '-ms-transform': rotate,
        'transform': rotate 
    });
});

An update if one is using Express 4.2 then the timeout middleware has been removed so need to manually add it with

npm install connect-timeout

and in the code it has to be (Edited as per comment, how to include it in the code)

 var timeout = require('connect-timeout');
 app.use(timeout('100s'));

Use a custom Listview.

The cleanest solution is probably to specify your divs as exact children.

Try changing this:

div.rounded div div {
    background: url('bl.gif') no-repeat bottom left;
}

To this:

div.rounded > div > div {
    background: url('bl.gif') no-repeat bottom left;
}

Another way of hiding the container div when a click happens in a not children element;

$(document).on('click', function(e) {
    if(!$.contains($('.yourContainer').get(0), e.target)) {
        $('.yourContainer').hide();
    }
});

If you want to rename multiple files in a single command - let's say you want to convert all *.txt files - here is the command:

find . -name "*.txt" -exec iconv -f WINDOWS-1252 -t UTF-8 {} -o {}.ren \; -a -exec mv {}.ren {} \;

Just remember set method to POST in options. Here is my code

var options = {
    url: 'http://www.example.com',
    method: 'POST', // Don't forget this line
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'X-MicrosoftAjax': 'Delta=true', // blah, blah, blah...
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36',
    },
    form: {
        'key-1':'value-1',
        'key-2':'value-2',
        ...
    }
};

//console.log('options:', options);

// Create request to get data
request(options, (err, response, body) => {
    if (err) {
        //console.log(err);
    } else {
        console.log('body:', body);
    }
});

Here's a possible solution that will color the entire row for your table.

CSS

tr.highlighted td {
    background: red;
}

jQuery

$('#data tr').click(function(e) {
    $('#data tr').removeClass('highlighted');
    $(this).toggleClass('highlighted');   
});

Demo: http://jsfiddle.net/jrthib/HVw7E/2/

As of jQuery 1.6 you should now call prop:

$target.prop("tagName")

See http://api.jquery.com/prop/

You can execute raw query using ActiveRecord. And I will suggest to go with SQL block

query = <<-SQL 
  SELECT * 
  FROM payment_details
  INNER JOIN projects 
          ON projects.id = payment_details.project_id
  ORDER BY payment_details.created_at DESC
SQL

result = ActiveRecord::Base.connection.execute(query)

Is there a js listener for when a user scrolls in a certain textbox that can be used?

DOM L3 UI Events spec gave the initial definition but is considered obsolete.

To add a single handler you can do:

  let isTicking;
  const debounce = (callback, evt) => {
    if (isTicking) return;
    requestAnimationFrame(() => {
      callback(evt);
      isTicking = false;
    });
    isTicking = true;
  };
  const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
  document.defaultView.onscroll = evt => debounce(handleScroll, evt);

For multiple handlers or, if preferable for style reasons, you may use addEventListener as opposed to assigning your handler to onscroll as shown above.

If using something like _.debounce from lodash you could probably get away with:

const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
document.defaultView.onscroll = evt => _.debounce(() => handleScroll(evt));

Review browser compatibility and be sure to test on some actual devices before calling it done.

This might be useful for refreshing also. But if you want to keep track of position on the page before you click on a same position.. The following code will help.

Also added a data-confirm for prompting the user if they really want to do that..

Note: I'm using jQuery and js-cookie.js to store cookie info.

$(document).ready(function() {
    // make all links with data-confirm prompt the user first.
    $('[data-confirm]').on("click", function (e) {
        e.preventDefault();
        var msg = $(this).data("confirm");
        if(confirm(msg)==true) {
            var url = this.href;
            if(url.length>0) window.location = url;
            return true;
        }
        return false;
    });

    // on certain links save the scroll postion.
    $('.saveScrollPostion').on("click", function (e) {
        e.preventDefault();
        var currentYOffset = window.pageYOffset;  // save current page postion.
        Cookies.set('jumpToScrollPostion', currentYOffset);
        if(!$(this).attr("data-confirm")) {  // if there is no data-confirm on this link then trigger the click. else we have issues.
            var url = this.href;
            window.location = url;
            //$(this).trigger('click');  // continue with click event.
        }
    });

    // check if we should jump to postion.
    if(Cookies.get('jumpToScrollPostion') !== "undefined") {
        var jumpTo = Cookies.get('jumpToScrollPostion');
        window.scrollTo(0, jumpTo);
        Cookies.remove('jumpToScrollPostion');  // and delete cookie so we don't jump again.
    }
});

A example of using it like this.

<a href='gotopage.html' class='saveScrollPostion' data-confirm='Are you sure?'>Goto what the heck</a>

Easy:

SELECT question_id, wm_concat(element_id) as elements
FROM   questions
GROUP BY question_id;

If it were not for the dashes and underscores, the easiest solution would be

my_little_string.isalnum()

(Section 3.6.1 of the Python Library Reference)

Try this (Note: I don't have right now Visual Studio ,so code is copy paste from my archive(I haven't test it) :

Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
    Dim drv As DataRowView
    If e.RowIndex >= 0 Then
        If e.RowIndex <= ds.Tables("Products").Rows.Count - 1 Then
            drv = ds.Tables("Products").DefaultView.Item(e.RowIndex)
            Dim c As Color
            If drv.Item("Quantity").Value < 5  Then
                c = Color.LightBlue
            Else
                c = Color.Pink
            End If
            e.CellStyle.BackColor = c
        End If
    End If
End Sub

What you request is quite a costy operation, make sure you don't need to do it often (e.g in a cycle).

If you need it to stay sorted and you update it frequently, you can create a custom collection. For example, I came up with one that has your TreeBidiMap and TreeMultiset under the hood. Implement only what you need and care about data integrity.

class MyCustomCollection implements Map<K, V> {
    TreeBidiMap<K, V> map;
    TreeMultiset<V> multiset;
    public V put(K key, V value) {
        removeValue(map.put(key, value));
        multiset.add(value);
    }
    public boolean remove(K key) {
        removeValue(map.remove(key));
    }
    /** removes value that was removed/replaced in map */
    private removeValue(V value) {
        if (value != null) {
            multiset.remove(value);
        }
    }
    public Set<K> keySet() {
        return Collections.unmodifiableSet(map.keySet());
    }
    public Collection<V> values() {
        return Collections.unmodifiableCollection(multiset);
    }
    // many more methods to be implemented, e.g. count, isEmpty etc.
    // but these are fairly simple
}

This way, you have a sorted Multiset returned from values(). However, if you need it to be a list (e.g. you need the array-like get(index) method), you'd need something more complex.

For brevity, I only return unmodifiable collections. What @Lino mentioned is correct, and modifying the keySet or values collection as it is would make it inconsistent. I don't know any consistent way to make the values mutable, but the keySet could support remove if it uses the remove method from the MyCustomCollection class above.

I can't comment on the accepted answer, due to low reputation. However, I would like to add, this behavior is by design. The NodeManager is killing your container. It sounds like you are trying to use hadoop streaming which is running as a child process of the map-reduce task. The NodeManager monitors the entire process tree of the task and if it eats up more memory than the maximum set in mapreduce.map.memory.mb or mapreduce.reduce.memory.mb respectively, we would expect the Nodemanager to kill the task, otherwise your task is stealing memory belonging to other containers, which you don't want.

Cause you need to add jQuery library to your file:

jQuery UI is just an addon to jQuery which means that
first you need to include the jQuery library → and then the UI.

<script src="path/to/your/jquery.min.js"></script>
<script src="path/to/your/jquery.ui.min.js"></script>

Java 8: Base64 available:

    MessageDigest md = MessageDigest.getInstance( "SHA-512" );
    md.update( inbytes );
    byte[] aMessageDigest = md.digest();

    String outEncoded = Base64.getEncoder().encodeToString( aMessageDigest );
    return( outEncoded );

It seems that I'm late on this issue and/or it has already been answered, but, what could be done is: (in my case, I had only one tag locally so.. I deleted the old tag and retagged it with:

git tag -d v1.0
git tag -a v1.0 -m "My commit message"

Then:

git push --tags -f

That will update all tags on remote.

Could be dangerous! Use at own risk.

One simple solution to this is to replace the item being changed in the ObservableCollection which notifies the collection of the changed item. In the sample code snippet below Artists is the ObservableCollection and artist is an item of the type in the ObservableCollection:

    var index = Artists.IndexOf(artist);
    Artists.RemoveAt(index);
    artist.IsFollowed = true; // change something in the item
    Artists.Insert(index, artist);

As of 1.10.5, simply include

'orderable: false'

in columnDefs and target your column with

'targets: [0,1]'

Table should like like:

var table = $('#data-tables').DataTable({
    columnDefs: [{
        targets: [0],
        orderable: false
    }]
});

I had got the same CORS error while working on a Vue.js project. You can resolve this either by building a proxy server or another way would be to disable the security settings of your browser (eg, CHROME) for accessing cross origin apis (this is temporary solution & not the best way to solve the issue). Both these solutions had worked for me. The later solution does not require any mock server or a proxy server to be build. Both these solutions can be resolved at the front end.

You can disable the chrome security settings for accessing apis out of the origin by typing the below command on the terminal:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir="/tmp/chrome_dev_session" --disable-web-security

After running the above command on your terminal, a new chrome window with security settings disabled will open up. Now, run your program (npm run serve / npm run dev) again and this time you will not get any CORS error and would be able to GET request using axios.

Hope this helps!

var text = "" &<>";
text = text.replaceHtmlEntites();

String.prototype.replaceHtmlEntites = function() {
var s = this;
var translate_re = /&(nbsp|amp|quot|lt|gt);/g;
var translate = {"nbsp": " ","amp" : "&","quot": "\"","lt"  : "<","gt"  : ">"};
return ( s.replace(translate_re, function(match, entity) {
  return translate[entity];
}) );
};

try this.....this worked for me

The following is a concise (and updated) summation of the earlier solutions. Here's what to do:

Add these strings and their respective parent keys:

pwrshell\(Default) < Open PowerShell Here
pwrshell\command\(Default) < powershell -NoExit -Command Set-Location -LiteralPath '%V'
pwrshelladmin\(Default) < Open PowerShell (Admin)
pwrshelladmin\command\(Default) < powershell -Command Start-Process -verb runAs -ArgumentList '-NoExit','cd','%V' powershell

at these locations

HKCR\Directory\shell (for folders)
HKCR\Directory\Background\shell (Explorer window)
HKCR\Drive\shell (for root drives)

That's it. Add the "Extended" strings for the commands only to be visible if you hold the "Shift" key, everything else is superfluous.

As asnwered here by @mcortesi if you remove the sourceMaps from the css loader query the css will be built without use of blob and the data urls will be parsed fine

To find any sub-string from large string:

string_value:=('This is String,Please search string 'Ple');

Then to find the string 'Ple' from String_value we can do as:

select substr(string_value,instr(string_value,'Ple'),length('Ple')) from dual;

You will find result: Ple

Using the placement feature of new operator, you can create the object in place and avoid copying:

placement (3) :void* operator new (std::size_t size, void* ptr) noexcept;

Simply returns ptr (no storage is allocated). Notice though that, if the function is called by a new-expression, the proper initialization will be performed (for class objects, this includes calling its default constructor).

I suggest the following:

A* arrayOfAs = new A[5]; //Allocate a block of memory for 5 objects
for (int i = 0; i < 5; ++i)
{
    //Do not allocate memory,
    //initialize an object in memory address provided by the pointer
    new (&arrayOfAs[i]) A(3);
}

string text = "Retrieves a substring from this instance. The substring starts at a specified character position. Some other text";

string result = text.Substring(text.IndexOf('.') + 1,text.LastIndexOf('.')-text.IndexOf('.'))

This will cut the part of string which lays between the special characters.

Creating URLs from strings is a minefield for bugs. Just miss a single / or accidentally URL encode the ? in a query and your API call will fail and your app won’t have any data to display (or even crash if you didn’t anticipate that possibility). Since iOS 8 there’s a better way to build URLs using NSURLComponents and NSURLQueryItems.

func createURLWithComponents() -> URL? {
    var urlComponents = URLComponents()
    urlComponents.scheme = "http"
    urlComponents.host = "maps.googleapis.com"
    urlComponents.path = "/maps/api/geocode/json"

    let addressQuery = URLQueryItem(name: "address", value: "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India")
    urlComponents.queryItems = [addressQuery]

    return urlComponents.url
}

Below is the code to access url using guard statement.

guard let url = createURLWithComponents() else {
            print("invalid URL")
            return nil
      }
      print(url)

Output:

http://maps.googleapis.com/maps/api/geocode/json?address=American%20Tourister,%20Abids%20Road,%20Bogulkunta,%20Hyderabad,%20Andhra%20Pradesh,%20India

Exe Application, first of all, references from a current directory to a subdirectory. And then, system directory. VS6.0 system directory was ..windows/system32. .NET system directory is like the below GAC path.

1. GAC path

   1) C:\Windows\Assembly (for .NET 2.0 ~ 3.5)

   2) C:\Windows\Microsoft.NET\assembly (for .NET 4.0)

2. How to install an assembly into GAC (as Administrator)

   1) Drag and Drop

   2) Use GacUtil.exe with Visual Studio Command Prompt

    gacutil -i [Path][Assembly Name].dll
   

   • Note: To install an assembly into the GAC, the assembly must be strongly named. Otherwise you get an error like this: Failure adding assembly to the cache: Attempt to install an assembly without a strong name.

3. How to uninstall an assembly from GAC (as Administrator)

    gacutil -u [Assembly Name], Version=1.0.0.0, PublickeyToken=7896a3567gh
   

   • Note: has no extention, .dll. Version and PublickeyToken can be omitted and be checked in GAC assembly.

            var maskROI = new Mat(mask, rect);
            maskROI.SetTo(new Scalar(0, 0, 0));

            // fill the contour
            Cv2.DrawContours(mask, contours, idx, Scalar.White, -1);

            // ratio of non-zero pixels in the filled region
            double r = (double)Cv2.CountNonZero(maskROI) / (rect.Width * rect.Height);
            if (r > .45 /* assume at least 45% of the area is filled if it contains text */
                 &&
            (rect.Height > 8 && rect.Width > 8) /* constraints on region size */
            /* these two conditions alone are not very robust. better to use something 
            like the number of significant peaks in a horizontal projection as a third condition */
            )
            {
                Cv2.Rectangle(rgb, rect, new Scalar(0, 255, 0), 2);
            }
        }

        rgb.SaveImage(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "rgb.jpg"));

You can use command

svn add * force--

or

svn add <directory/file name>

If your files/directories are not adding recursively. Then check this.

Recursive adding is default property. You can see in SVN book.

Issue can be in your ignore list or global properties.

I got solution google issue tracker

Check global properties for ignoring star(*)

• Right click in your repo in window. Select TortoiseSVN > Properties.
• See if you don't have a property svn:global-ignores with a value of *
• If you have property with star(*) then it will ignore recursive adding. So remove this property.

Check global ignore pattern for ignoring star(*)

• Right click in your repo in window. Select TortoiseSVN > Settings > General.
• See in Global Ignore Pattern, if you don't have set star(*) there.
• If you found star(*), remove this property.

This guy also explained why this property added in my project.

The most like way that it got there is that someone right-clicked a file without any extension and selected TortoiseSVN -> SVN Ignore -> * (recursively), and then committed this.

You can check the log to see who committed that property change, find out what they were actually trying to do, and ask them to be more careful in future. :)

There is also a POSIX library for POSIX operating systems. Check for compatability

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

void *task(void *argument){
      char* msg;
      msg = (char*)argument;
      std::cout<<msg<<std::endl;
}

int main(){
    pthread_t thread1, thread2;
    int i1,i2;
    i1 = pthread_create( &thread1, NULL, task, (void*) "thread 1");
    i2 = pthread_create( &thread2, NULL, task, (void*) "thread 2");

    pthread_join(thread1,NULL);
    pthread_join(thread2,NULL);
    return 0;

}

compile with -lpthread

http://en.wikipedia.org/wiki/POSIX_Threads

They are extension methods. Welcome to a whole new fluent world. :)

This can also be used

$('#name2').change(function(){
    $('#name').val('');//You can set the first value of first one if that is not empty
});


$('#name').change(function(){
    $('#name2').val('');
});

There is a very effective way to use to clear or reset Windows Form C# controls like TextBox, ComboBox, RadioButton, CheckBox, DateTimePicker etc.

private void btnClear_Click(object sender, EventArgs e)
{
    Utilities.ClearAllControls(this);
}

internal class Utilities
{
    internal static void ClearAllControls(Control control)
    {
        foreach (Control c in control.Controls)
        {
            if (c is TextBox)
            {
                ((TextBox)c).Clear();
            }
            else if (c is ComboBox)
            {
                ((ComboBox)c).SelectedIndex = -1;
            }
            else if (c is RadioButton)
            {
                ((RadioButton)c).Checked = false;
            }
            else if (c is CheckBox)
            {
                ((CheckBox)c).Checked = false;
            }
            else if (c is DateTimePicker)
            {
                ((DateTimePicker)c).Value = DateTime.Now; // or null 
            }
        }
    }
}

To accomplish this with overall user experience in c# we can use one statement to clear them. Pretty straight forward so far, above is the code.

this type of error generally occurs when you have to put characters or values more than that you have specified in Database table like in this case: you specify transaction_status varchar(10) but you actually trying to store
_transaction_status which contain 19 characters. that's why you faced this type of error in this code..

Use this if you also want to consider non-javascript users:

echo ("<SCRIPT LANGUAGE='JavaScript'>
           window.alert('Succesfully Updated')
           window.location.href='http://someplace.com';
       </SCRIPT>
       <NOSCRIPT>
           <a href='http://someplace.com'>Successfully Updated. Click here if you are not redirected.</a>
       </NOSCRIPT>");

HTML4 specification states that:

Inline elements may contain only data and other inline elements

Span is an inline element, therefore having span inside span is valid. There's a related question: Can <span> tags have any type of tags inside them? which makes it completely clear.

HTML5 specification (including the most current draft of HTML 5.3 dated November 16, 2017) changes terminology, but it's still perfectly valid to place span inside another span.

Some clarifications (not really an answer)

In kubernetes, every pod gets assigned an IP address, and every container in the pod gets assigned that same IP address. Thus, as Alex Robinson stated in his answer, you can just use hostname -i inside your container to get the pod IP address.

I tested with a pod running two dumb containers, and indeed hostname -i was outputting the same IP address inside both containers. Furthermore, that IP was equivalent to the one obtained using kubectl describe pod from outside, which validates the whole thing IMO.

However, PiersyP's answer seems more clean to me.

Sources

From kubernetes docs:

The applications in a pod all use the same network namespace (same IP and port space), and can thus “find” each other and communicate using localhost. Because of this, applications in a pod must coordinate their usage of ports. Each pod has an IP address in a flat shared networking space that has full communication with other physical computers and pods across the network.

Another piece from kubernetes docs:

Until now this document has talked about containers. In reality, Kubernetes applies IP addresses at the Pod scope - containers within a Pod share their network namespaces - including their IP address. This means that containers within a Pod can all reach each other’s ports on localhost.

As to why this still exists - MS doesn't consider it a priority, and values backwards compatibility over advancing their OS (at least in this instance).

A workaround I use is to use the "short names" for the directories in the path, instead of their standard, human-readable versions. So e.g. for C:\Program Files\ I would use C:\PROGRA~1\ You can find the short name equivalents using dir /x.

select right(rtrim('94342KMR'),3)

This will fetch the last 3 right string.

select substring(rtrim('94342KMR'),1,len('94342KMR')-3)

This will fetch the remaining Characters.

If you have YAML that conforms to the YAML 1.2 specification (released 2009) then you should use ruamel.yaml (disclaimer: I am the author of that package). It is essentially a superset of PyYAML, which supports most of YAML 1.1 (from 2005).

If you want to be able to preserve your comments when round-tripping, you certainly should use ruamel.yaml.

Upgrading @Jon's example is easy:

import ruamel.yaml as yaml

with open("example.yaml") as stream:
    try:
        print(yaml.safe_load(stream))
    except yaml.YAMLError as exc:
        print(exc)

Use safe_load() unless you really have full control over the input, need it (seldom the case) and know what you are doing.

If you are using pathlib Path for manipulating files, you are better of using the new API ruamel.yaml provides:

from ruamel.yaml import YAML
from pathlib import Path

path = Path('example.yaml')
yaml = YAML(typ='safe')
data = yaml.load(path)

If all you need is the "MST" or the "EST" time zone abbreviation:

function getTimeZone(){
    var now = new Date().toString();
    var timeZone = now.replace(/.*[(](.*)[)].*/,'$1');//extracts the content between parenthesis
    return timeZone;
}
console.log(getTimeZone());

This may come a bit too late, but I have written something for this very purpose. My library will mock out the basic crud repository methods for you as well as interpret most of the functionalities of your query methods. You will have to inject functionalities for your own native queries, but the rest are done for you.

Take a look:

UPDATE

This is now in Maven central and in pretty good shape.

Experimenting, I found a solution using <div…/> but an obvious solution is to place your own anchor point in the page wherever you like, thus:

<a name="abcde">

before and

</a>

after the line you want to "link" to. Then a markdown link like:

[link text](#abcde)

anywhere in the document takes you there.

The <div…/> solution inserts a "dummy" division just to add the id property, and this is potentially disruptive to the page structure, but the <a name="abcde"/> solution ought to be quite innocuous.

(PS: It might be OK to put the anchor in the line you wish to link to, as follows:

## <a name="head1">Heading One</a>

but this depends on how Markdown treats this. I note, for example, the Stack Overflow answer formatter is happy with this!)

TxtFarmerSize.Text = (int)reader[3];

I had a similar-looking problem after adding a directory tree which contained .svn directories (because it was an svn:external in its source environment): svn status told me "?", but when trying to add it, it was "already under version control".

Since no other versioned directories were present, I did

find . -mindepth 2 -name '.svn' -exec rm -rf '{}' \;

to remove the wrong .svn directories; after doing this, I was able to add the new directory.

Note:

• If other versioned directories are contained, the find expression must be changed to be more specific
• If unsure, first omit the "-exec ..." part to see what would be deleted

The free and open-source program called cabextract will list and extract the contents of not just .cab-files, but Macrovision's archives too:

% cabextract /tmp/QLWREL.EXE
Extracting cabinet: /tmp/QLWREL.EXE
  extracting ikernel.dll
  extracting IsProBENT.tlb
  ....
  extracting IScript.dll
  extracting iKernel.rgs

All done, no errors.

here is the example using Pure JavaScript

function scrollpage() {  _x000D_
 function f() _x000D_
 {_x000D_
  window.scrollTo(0,i);_x000D_
  if(status==0) {_x000D_
      i=i+40;_x000D_
   if(i>=Height){ status=1; } _x000D_
  } else {_x000D_
   i=i-40;_x000D_
   if(i<=1){ status=0; }  // if you don't want continue scroll then remove this line_x000D_
  }_x000D_
 setTimeout( f, 0.01 );_x000D_
 }f();_x000D_
}_x000D_
var Height=document.documentElement.scrollHeight;_x000D_
var i=1,j=Height,status=0;_x000D_
scrollpage();_x000D_
</script>

<style type="text/css">_x000D_
_x000D_
 #top { border: 1px solid black;  height: 20000px; }_x000D_
 #bottom { border: 1px solid red; }_x000D_
_x000D_
</style>

<div id="top">top</div>_x000D_
<div id="bottom">bottom</div>

PHP arrays have internal pointers, so try this:

foreach($array as $key => $value){
   $index = current($array);
}

Works okay for me (only very preliminarily tested though).

Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.

Use the subplots_adjust() function to move the bottom of the subplot up:

fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.

Then play with the offset in the legend bbox_to_anchor part of the legend command, to get the legend box where you want it. Some combination of setting the figsize and using the subplots_adjust(bottom=...) should produce a quality plot for you.

Alternative: I simply changed the line:

fig = plt.figure(1)

to:

fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')

and changed

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))

to

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))

and it shows up fine on my screen (a 24-inch CRT monitor).

Here figsize=(M,N) sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport option when including graphics.

There are two branches to this question (Rolling back a commit does not mean I want to lose all my local changes):

1. To revert the latest commit and discard changes in the committed file do:

git reset --hard HEAD~1

2. To revert the latest commit but retain the local changes (on disk) do:

git reset --soft HEAD~1

This (the later command) will take you to the state you would have been if you did git add.

If you want to unstage the files after that, do

git reset

Now you can make more changes before adding and then committing again.

Unfortunately no solutions from given here worked for several dialogs on the page.

Also the problem was that original dialog doesn't contain button pane in itself, but is a sibling of it.

So I came up with selecting by dialog ID like that:

        var getFirstDialogButton = function (dialogSelector) {
            return $('.ui-dialog-buttonpane button:first',
                    $(dialogSelector).parent()[0]);
        };

...

        $('#my_dialog').dialog({
            open: function(event, ui) {
                getFirstDialogButton("#my_dialog")
                 .addClass("ui-state-disabled").attr('disabled', 'disabled' );
            },

...

and then the same getFirstDialogButton() function could be later used to enable button, e.g. after successful validation.

Hope it can help someone.

In NuGet 3.0 the Get-Package command is deprecated and replaced with Find-Package command.

Find-Package Common.Logging -AllVersions

See the NuGet command reference docs for details.

This is the message shown if you try to use Get-Package in Visual Studio 2015.

This Command/Parameter combination has been deprecated and will be removed
in the next release. Please consider using the new command that replaces it: 
'Find-Package [-Id] -AllVersions'

Or as @Yishai said, you can use the version number dropdown in the NuGet screen in Visual Studio.

A fundamental mistake is here:

result = methodInfo.Invoke(methodInfo, parametersArray); 

You are invoking the method on an instance of MethodInfo. You need to pass in an instance of the type of object that you want to invoke on.

result = methodInfo.Invoke(classInstance, parametersArray);

What @dmckee said.

It's not difficult to write your own bespoke footnote-queuing code. What you need to do is:

1. Write code to queue Latex code — like a hook in emacs: very standard technique, if not every Latex hacker can actually do this right;
2. Temporarily redefine \footnote to add a footnote macro to your queue;
3. Ensure that the hook gets called when the table/figure exits and we return to regular vertical mode.

If this is interesting, I show some code that does this.

Because you can ask the server to prepend a prefix to the returned JSON object. E.g

function_prefix(json_object);

in order for the browser to eval "inline" the JSON string as an expression. This trick makes it possible for the server to "inject" javascript code directly in the Client browser and this with bypassing the "same origin" restrictions.

In other words, you can achieve cross-domain data exchange.

Normally, XMLHttpRequest doesn't permit cross-domain data-exchange directly (one needs to go through a server in the same domain) whereas:

<script src="some_other_domain/some_data.js&prefix=function_prefix>` one can access data from a domain different than from the origin.

Also worth noting: even though the server should be considered as "trusted" before attempting that sort of "trick", the side-effects of possible change in object format etc. can be contained. If a function_prefix (i.e. a proper js function) is used to receive the JSON object, the said function can perform checks before accepting/further processing the returned data.

What exactly do you want to know? ActiveRecord has methods that serialize records into JSON. For instance, open up your rails console and enter ModelName.all.to_json and you will see JSON output. render :json essentially calls to_json and returns the result to the browser with the correct headers. This is useful for AJAX calls in JavaScript where you want to return JavaScript objects to use. Additionally, you can use the callback option to specify the name of the callback you would like to call via JSONP.

For instance, lets say we have a User model that looks like this: {name: 'Max', email:' [email protected]'}

We also have a controller that looks like this:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user
    end
end

Now, if we do an AJAX call using jQuery like this:

$.ajax({
    type: "GET",
    url: "/users/5",
    dataType: "json",
    success: function(data){
        alert(data.name) // Will alert Max
    }        
});

As you can see, we managed to get the User with id 5 from our rails app and use it in our JavaScript code because it was returned as a JSON object. The callback option just calls a JavaScript function of the named passed with the JSON object as the first and only argument.

To give an example of the callback option, take a look at the following:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user, callback: "testFunction"
    end
end

Now we can crate a JSONP request as follows:

function testFunction(data) {
    alert(data.name); // Will alert Max
};

var script = document.createElement("script");
script.src = "/users/5";

document.getElementsByTagName("head")[0].appendChild(script);

The motivation for using such a callback is typically to circumvent the browser protections that limit cross origin resource sharing (CORS). JSONP isn't used that much anymore, however, because other techniques exist for circumventing CORS that are safer and easier.

I am beginner to iOS development so I would like to share whole info I got in this section.

First from image assets (images.xcassets) create image set .

According to Documentation here is all sizes need to create background image.

For iPhone 5:
   640 x 1136

   For iPhone 6:
   750 x 1334 (@2x) for portrait
   1334 x 750 (@2x) for landscape

   For iPhone 6 Plus:
   1242 x 2208 (@3x) for portrait
   2208 x 1242 (@3x) for landscape

   iPhone 4s (@2x)      
   640 x 960

   iPad and iPad mini (@2x) 
   1536 x 2048 (portrait)
   2048 x 1536 (landscape)

   iPad 2 and iPad mini (@1x)
   768 x 1024 (portrait)
   1024 x 768 (landscape)

   iPad Pro (@2x)
   2048 x 2732 (portrait)
   2732 x 2048 (landscape)

call the image background we can call image from image assets by using this method UIImage(named: "background") here is full code example

  override func viewDidLoad() {
          super.viewDidLoad()
             assignbackground()
            // Do any additional setup after loading the view.
        }

  func assignbackground(){
        let background = UIImage(named: "background")

        var imageView : UIImageView!
        imageView = UIImageView(frame: view.bounds)
        imageView.contentMode =  UIViewContentMode.ScaleAspectFill
        imageView.clipsToBounds = true
        imageView.image = background
        imageView.center = view.center
        view.addSubview(imageView)
        self.view.sendSubviewToBack(imageView)
    }

Here's a practical reason to prefer functions over stored procedures. If you have a stored procedure that needs the results of another stored procedure, you have to use an insert-exec statement. This means that you have to create a temp table and use an exec statement to insert the results of the stored procedure into the temp table. It's messy. One problem with this is that insert-execs cannot be nested.

If you're stuck with stored procedures that call other stored procedures, you may run into this. If the nested stored procedure simply returns a dataset, it can be replaced with a table-valued function and you'll no longer get this error.

(this is yet another reason we should keep business logic out of the database)

I was facing same issue in my Spring Integration project. I added below JSON dependencies in pom.xml file. It works for me.

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20090211</version>
</dependency>

A list of versions can be found here: https://mvnrepository.com/artifact/org.json/json

and in jquery:

$('element').attr('some attribute','some attributes value')

i.e

$('a').attr('href','http://www.stackoverflow.com/')

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)

#include <iostream>

int main()
{
    std::cout<<"Hello World!\n";
    return 0;
}

I'm not sure about bash-like environment. You might try some simple wrapper programs in Java (with program arguments) that invoke your MBeans on the remote server. You can then call these wrappers from the shell script

If you can use something like Python or Perl, you might be interested in JSR-262 which allows you to expose JMX operations over web services. This is scheduled to be included in Java 7 but you might be able to use a release candidate of the reference implementation

You can use git cherry-pick to just pick the commit that you want to copy over.

Probably the best way is to create the branch out of master, then in that branch use git cherry-pick on the 2 commits from quickfix2 that you want.

Found an elegant solution using decorators, which addresses the following problem: what if you are writing a module with several functions, each of them with several debugging messages, and you want to disable logging in all functions but the one you are currently focusing on?

You can do it using decorators:

import logging, sys
logger = logging.getLogger()
logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)


def disable_debug_messages(func):
    def wrapper(*args, **kwargs):
        prev_state = logger.disabled
        logger.disabled = True
        result = func(*args, **kwargs)
        logger.disabled = prev_state
        return result
    return wrapper

Then, you can do:

@disable_debug_messages
def function_already_debugged():
    ...
    logger.debug("This message won't be showed because of the decorator")
    ...

def function_being_focused():
    ...
    logger.debug("This message will be showed")
    ...

Even if you call function_already_debugged from within function_being_focused, debug messages from function_already_debugged won't be showed. This ensures you will see only the debug messages from the function you are focusing on.

Hope it helps!

I also had to do this myself. I did it via the --parents argument for cp:

find SOURCEPATH -name filename*.txt -exec cp --parents {} DESTPATH \;

I don't know what the correct answer was in '13, but today it is:

myEditText.setKeyListener(DigitsKeyListener.getInstance(null, false, true)); // positive decimal numbers

You get everything, including the onscreen keyboard is a numeric keypad.

ALMOST everything. Espresso, in its infinite wisdom, lets typeText("...") inexplicably bypass the filter and enter garbage...

Converted the input file to include \N for the blank column data using the below sed command in UNix terminal:

sed -i 's/,,/,\\N,/g' $file_name

and then use LOAD DATA INFILE command to load to mysql

I've found that the easiest way to have non-standard fonts on a website is to use sIFR

It does involve the use of a Flash object that contains the font, but it degrades nicely to standard text / font if Flash is not installed.

The style is set in your CSS, and JavaScript sets up the Flash replacement for your text.

Edit: (I still recommend using images for non-standard fonts as sIFR adds time to a project and can require maintenance).

You can use the tee command to redirect output:

/usr/bin/mysqldump -u user -pupasswd my-database | \
tee >(gzip -9 -c > /home/user/backup/mydatabase-backup-`date +\%m\%d_\%Y`.sql.gz)  | \
gzip> /home/user/backup2/mydatabase-backup-`date +\%m\%d_\%Y`.sql.gz 2>&1

see documentation here

ldapwhoami -vvv -h <hostname> -p <port> -D <binddn> -x -w <passwd>, where binddn is the DN of the person whose credentials you are authenticating.

On success (i.e., valid credentials), you get Result: Success (0). On failure, you get ldap_bind: Invalid credentials (49).

imageView.setImageBitmap(BitmapFactory.decodeStream(imageUrl.openStream()));//try/catch IOException and MalformedURLException outside

If you have one large dataframe and only a few update values I would use apply like this:

import pandas as pd

df = pd.DataFrame({'filename' :  ['test0.dat', 'test2.dat'], 
                                  'm': [12, 13], 'n' : [None, None]})

data = {'filename' :  'test2.dat', 'n':16}

def update_vals(row, data=data):
    if row.filename == data['filename']:
        row.n = data['n']
    return row

df.apply(update_vals, axis=1)

There is comma missing in your tuple.

insert the comma between the tuples as shown:

This is a bad programming practice, and not allowed in C#. It's a bad programming practice because

• The details of the grandbase are implementation details of the base; you shouldn't be relying on them. The base class is providing an abstraction overtop of the grandbase; you should be using that abstraction, not building a bypass to avoid it.

• To illustrate a specific example of the previous point: if allowed, this pattern would be yet another way of making code susceptible to brittle-base-class failures. Suppose C derives from B which derives from A. Code in C uses base.base to call a method of A. Then the author of B realizes that they have put too much gear in class B, and a better approach is to make intermediate class B2 that derives from A, and B derives from B2. After that change, code in C is calling a method in B2, not in A, because C's author made an assumption that the implementation details of B, namely, that its direct base class is A, would never change. Many design decisions in C# are to mitigate the likelihood of various kinds of brittle base failures; the decision to make base.base illegal entirely prevents this particular flavour of that failure pattern.

• You derived from your base because you like what it does and want to reuse and extend it. If you don't like what it does and want to work around it rather than work with it, then why did you derive from it in the first place? Derive from the grandbase yourself if that's the functionality you want to use and extend.

• The base might require certain invariants for security or semantic consistency purposes that are maintained by the details of how the base uses the methods of the grandbase. Allowing a derived class of the base to skip the code that maintains those invariants could put the base into an inconsistent, corrupted state.

Maybe you can use TextFX plugins

It's implementation-specific, but in practice the rule (in the absence of #pragma pack or the like) is:

• Struct members are stored in the order they are declared. (This is required by the C99 standard, as mentioned here earlier.)
• If necessary, padding is added before each struct member, to ensure correct alignment.
• Each primitive type T requires an alignment of sizeof(T) bytes.

So, given the following struct:

struct ST
{
   char ch1;
   short s;
   char ch2;
   long long ll;
   int i;
};

• ch1 is at offset 0
• a padding byte is inserted to align...
• s at offset 2
• ch2 is at offset 4, immediately after s
• 3 padding bytes are inserted to align...
• ll at offset 8
• i is at offset 16, right after ll
• 4 padding bytes are added at the end so that the overall struct is a multiple of 8 bytes. I checked this on a 64-bit system: 32-bit systems may allow structs to have 4-byte alignment.

So sizeof(ST) is 24.

It can be reduced to 16 bytes by rearranging the members to avoid padding:

struct ST
{
   long long ll; // @ 0
   int i;        // @ 8
   short s;      // @ 12
   char ch1;     // @ 14
   char ch2;     // @ 15
} ST;

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

In some cases a one-way request without a response can be fired to a TCP server, without a SSL certificate. A TCP server, in contrast to a HTTP server, will catch you request. However there will be no access to any data sent from the browser, because the browser will not send any data without a positive certificate check. And in special cases even a bare TCP signal without any data is enough to execute some tasks. For example for an IoT device within a LAN to start a connection to an external service. Link

This is a kind of a "Wake Up" trigger, that works on a port without any security.

In case a response is needed, this can be implemented using a secured public https server, which can send the needed data back to the browser using e.g. Websockets.

If you set the cookie to expire in the past, the browser will remove it. See setcookie() delete example at php.net

I have used jQuery AJAX to make AJAX requests.

Check the following code:

<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $('#call').click(function ()
            {
                $.ajax({
                    type: "post",
                    url: "testme", //this is my servlet
                    data: "input=" +$('#ip').val()+"&output="+$('#op').val(),
                    success: function(msg){      
                            $('#output').append(msg);
                    }
                });
            });

        });
    </script>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

I think you have found an example where auto-boxing doesn't really work. Because Arrays.asList(T... a) has a varargs parameter the compiler apparently considers the int[] and returns a List<int[]> with a single element in it.

You should change the method into this:

public int getTheNumber(Integer[] factors) {
    ArrayList<Integer> f = new ArrayList<Integer>(Arrays.asList(factors));  
    Collections.sort(f);
    return f.get(0) * f.get(f.size() - 1);
}

and possibly add this for compatibility

public int getTheNumber(int[] factors) {
    Integer[] factorsInteger = new Integer[factors.length];
    for(int ii=0; ii<factors.length; ++ii) {
        factorsInteger[ii] = factors[ii];
    }

    return getTheNumber(factorsInteger);
}

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Result:

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

It passes control to the next matching route. In the example you give, for instance, you might look up the user in the database if an id was given, and assign it to req.user.

Below, you could have a route like:

app.get('/users', function(req, res) {
  // check for and maybe do something with req.user
});

Since /users/123 will match the route in your example first, that will first check and find user 123; then /users can do something with the result of that.

Route middleware is a more flexible and powerful tool, though, in my opinion, since it doesn't rely on a particular URI scheme or route ordering. I'd be inclined to model the example shown like this, assuming a Users model with an async findOne():

function loadUser(req, res, next) {
  if (req.params.userId) {
    Users.findOne({ id: req.params.userId }, function(err, user) {
      if (err) {
        next(new Error("Couldn't find user: " + err));
        return;
      }

      req.user = user;
      next();
    });
  } else {
    next();
  }
}

// ...

app.get('/user/:userId', loadUser, function(req, res) {
  // do something with req.user
});

app.get('/users/:userId?', loadUser, function(req, res) {
  // if req.user was set, it's because userId was specified (and we found the user).
});

// Pretend there's a "loadItem()" which operates similarly, but with itemId.
app.get('/item/:itemId/addTo/:userId', loadItem, loadUser, function(req, res) {
  req.user.items.append(req.item.name);
});

Being able to control flow like this is pretty handy. You might want to have certain pages only be available to users with an admin flag:

/**
 * Only allows the page to be accessed if the user is an admin.
 * Requires use of `loadUser` middleware.
 */
function requireAdmin(req, res, next) {
  if (!req.user || !req.user.admin) {
    next(new Error("Permission denied."));
    return;
  }

  next();
}

app.get('/top/secret', loadUser, requireAdmin, function(req, res) {
  res.send('blahblahblah');
});

Hope this gave you some inspiration!

Here's a gotcha that I just discovered - perhaps it might help someone else. If using windows the classes folder must not have encryption enabled! Tomcat doesn't seem to like that. Right click on the classes folder, select "Properties" and then click the "Advanced..." button. Make sure the "Encrypt contents to secure data" checkbox is cleared. Restart Tomcat.

It worked for me so here's hoping it helps someone else, too.

You are using an inline table value function. Therefore you must use Select * From function. If you want to use select function() you must use a scalar function.

If you want to hide this warn, you just need to install fsevents as a optional dependency. Just execute:

npm i fsevents@latest -f --save-optional

..And the warn will no longer be a bother.

use style instead like

<div style="display:none;"></div>

I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:

GET approach with JSON result

curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool 

POST approach with JSON result

curl -X POST  -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool

In answer to Shubham Patwa: This way, the page is "jumpy" soon as the class "navbar-fixed-top" applies. That's because the #mainnav is throwen in and out of the document's DOM flow. This can result in an ugly UX if the page has a "critical height", jumping between fixed and un-fixed #mainnav position.

I altered the code this way, which seems to work fine (not pixel-perfect, but fine):

$(document).ready(function() {
  var navpos = $('#mainnav').offset();
  var navheight = $('#mainnav').outerHeight();

$(window).bind('scroll', function() {
  if ($(window).scrollTop() > navpos.top) {
   $('#mainnav').addClass('navbar-fixed-top');
   $('body').css('marginTop',navheight);
   }
   else {
     $('#mainnav').removeClass('navbar-fixed-top');
     $('body').css('marginTop','0');
   }
});

Objective C Solution

NSArray * array = @[@"1", @"2", @"3"];
NSString * stringFromArray = [[array valueForKey:@"description"] componentsJoinedByString:@"-"];   // "1-2-3"

Those who are looking for a solution in Swift

If the array contains strings, you can use the String's join method:

var array = ["1", "2", "3"]

let stringFromArray = "-".join(array) // "1-2-3"

In Swift 2:

var array = ["1", "2", "3"]

let stringFromArray = array.joinWithSeparator("-") // "1-2-3"

In Swift 3 & 4

var array = ["1", "2", "3"]

let stringFromArray = array.joined(separator: "-") // "1-2-3"

EXPECT is a great program to use.

On Ubuntu install it with:

sudo apt-get install expect

On a CentOS Machine install it with:

yum install expect

Lets say you want to make a connection to a sftp server and then upload a local file from your local machine to the remote sftp server

#!/usr/bin/expect

spawn sftp [email protected]
expect "password:"
send "yourpasswordhere\n"
expect "sftp>"
send "cd logdirectory\n"
expect "sftp>"
send "put /var/log/file.log\n"
expect "sftp>"
send "exit\n"
interact

This opens a sftp connection with your password to the server.

Then it goes to the directory where you want to upload your file, in this case "logdirectory"

This uploads a log file from the local directory found at /var/log/ with the files name being file.log to the "logdirectory" on the remote server

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

For MAC OSX (El Capitan) This modification of Nicholas' example worked for me.

for pem in /path/to/certs/*.pem; do
    printf '%s: %s\n' \
        "$(date -jf "%b %e %H:%M:%S %Y %Z" "$(openssl x509 -enddate -noout -in "$pem"|cut -d= -f 2)" +"%Y-%m-%d")" \
    "$pem";
done | sort

Sample Output:

2014-12-19: /path/to/certs/MDM_Certificate.pem
2015-11-13: /path/to/certs/MDM_AirWatch_Certificate.pem

macOS didn't like the --date= or --iso-8601 flags on my system.

utf-8 code error usually comes when the range of numeric values exceeding 0 to 127.

the reason to raise this exception is:

1)If the code point is < 128, each byte is the same as the value of the code point. 2)If the code point is 128 or greater, the Unicode string can’t be represented in this encoding. (Python raises a UnicodeEncodeError exception in this case.)

In order to to overcome this we have a set of encodings, the most widely used is "Latin-1, also known as ISO-8859-1"

So ISO-8859-1 Unicode points 0–255 are identical to the Latin-1 values, so converting to this encoding simply requires converting code points to byte values; if a code point larger than 255 is encountered, the string can’t be encoded into Latin-1

when this exception occurs when you are trying to load a data set ,try using this format

df=pd.read_csv("top50.csv",encoding='ISO-8859-1')

Add encoding technique at the end of the syntax which then accepts to load the data set.

You may also want to look at new code protection technologies such as Metaforic and V.i.Labs and new software copy protection technologies such as ByteShield. Disclosure: I work for ByteShield.

I don't think it actually does much, it looks like it's just a cache for string literals. If you have multiple Strings who's values are the same, they'll all point to the same string literal in the string pool.

String s1 = "Arul"; //case 1 
String s2 = "Arul"; //case 2 

In case 1, literal s1 is created newly and kept in the pool. But in case 2, literal s2 refer the s1, it will not create new one instead.

if(s1 == s2) System.out.println("equal"); //Prints equal. 

String n1 = new String("Arul"); 
String n2 = new String("Arul"); 
if(n1 == n2) System.out.println("equal"); //No output.

You can use functional operation for a more neat code

Set<String> set = new HashSet<String>();

set.forEach((s) -> {
     System.out.println(s);
});

@Be.St.'s aprroach is true, but incomplete. I'm just copying his explanation with correcting the incorrect part.

IIS express configuration is managed by applicationhost.config.
You can find it in

Users\<username>\Documents\IISExpress\config folder.

Inside you can find the sites section that hold a section for each IIS Express configured site.

Add (or modify) a site section like this:

<site name="WebSiteWithVirtualDirectory" id="20">
   <application path="/" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="c:\temp\website1" />
     <virtualDirectory path="/OffSiteStuff" physicalPath="d:\temp\SubFolderApp" />
   </application>
   <bindings>
      <binding protocol="http" bindingInformation="*:1132:localhost" />
   </bindings>
</site>

Instead of adding a new application block, you should just add a new virtualDirectory element to the application parent element.

Edit - Visual Studio 2015

If you're looking for the applicationHost.config file and you're using VS2015 you'll find it in:

[solution_directory]/.vs/config/applicationHost.config

A const object is always static.

Regarding the suggestion So I would suggest that you use WebClient and investigate the causes of the 30 second delay.

From the answers for the question System.Net.WebClient unreasonably slow

Try setting Proxy = null;

WebClient wc = new WebClient(); wc.Proxy = null;

C++. This should be reasonably quick, as it doesn't require iterating over the whole set, or sorting it. This should work out of the box with most modern compilers, assuming they support tr1. If not, you may need to use Boost.

The Boost docs are helpful here to explain this, even if you don't use Boost.

The trick is to make use of the fact that the data has been divided into buckets, and to quickly identify a randomly chosen bucket (with the appropriate probability).

//#include <boost/unordered_set.hpp>  
//using namespace boost;
#include <tr1/unordered_set>
using namespace std::tr1;
#include <iostream>
#include <stdlib.h>
#include <assert.h>
using namespace std;

int main() {
  unordered_set<int> u;
  u.max_load_factor(40);
  for (int i=0; i<40; i++) {
    u.insert(i);
    cout << ' ' << i;
  }
  cout << endl;
  cout << "Number of buckets: " << u.bucket_count() << endl;

  for(size_t b=0; b<u.bucket_count(); b++)
    cout << "Bucket " << b << " has " << u.bucket_size(b) << " elements. " << endl;

  for(size_t i=0; i<20; i++) {
    size_t x = rand() % u.size();
    cout << "we'll quickly get the " << x << "th item in the unordered set. ";
    size_t b;
    for(b=0; b<u.bucket_count(); b++) {
      if(x < u.bucket_size(b)) {
        break;
      } else
        x -= u.bucket_size(b);
    }
    cout << "it'll be in the " << b << "th bucket at offset " << x << ". ";
    unordered_set<int>::const_local_iterator l = u.begin(b);
    while(x>0) {
      l++;
      assert(l!=u.end(b));
      x--;
    }
    cout << "random item is " << *l << ". ";
    cout << endl;
  }
}

Tags can be either signed or unsigned; branches are never signed.

Signed tags can never move because they are cryptographically bound (with a signature) to a particular commit. Unsigned tags are not bound and it is possible to move them (but moving tags is not a normal use case).

Branches can not only move to a different commit but are expected to do so. You should use a branch for your local development project. It doesn't quite make sense to commit work to a Git repository "on a tag".

I was trying to put a transparent HTML overlay over my GL view but it has always black flickering which covers my GL view. After several days trying to get rid of this flickering I found this workaround which is acceptable for me (but a shame for android).

The problem is that I need hardware acceleration for my nice CSS animations and so webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); is not an option for me.

The trick was to put a second (empty) WebView between my GL view and the HTML overlay. This dummyWebView I told to render in SW mode, and now my HTML overlays renders smooth in HW and no more black flickering.

I don't know if this works on other devices than My Acer Iconia A700, but I hope I could help someone with this.

public class MyActivity extends Activity {

    @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);

        RelativeLayout layout = new RelativeLayout(getApplication());
        setContentView(layout);

        MyGlView glView = new MyGlView(this);

        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);

        dummyWebView = new WebView(this);
        dummyWebView.setLayoutParams(params);
        dummyWebView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        dummyWebView.loadData("", "text/plain", "utf8");
        dummyWebView.setBackgroundColor(0x00000000);

        webView = new WebView(this);
        webView.setLayoutParams(params);
        webView.loadUrl("http://10.0.21.254:5984/ui/index.html");
        webView.setBackgroundColor(0x00000000);


        layout.addView(glView);
        layout.addView(dummyWebView);
        layout.addView(webView);
    }
}

Update for mid 2016:

The things are changing so fast that if it's late 2017 this answer might not be up to date anymore!

Beginners can quickly get lost in choice of build tools and workflows, but what's most up to date in 2016 is not using Bower, Grunt or Gulp at all! With help of Webpack you can do everything directly in NPM!

• Google "npm as build tool" result: https://medium.com/@dabit3/introduction-to-using-npm-as-a-build-tool-b41076f488b0#.c33e74tsa

• Webpack: https://webpack.github.io/docs/installation.html

Don't get me wrong people use other workflows and I still use GULP in my legacy project(but slowly moving out of it), but this is how it's done in the best companies and developers working in this workflow make a LOT of money!

Look at this template it's a very up-to-date setup consisting of a mixture of the best and the latest technologies: https://github.com/coryhouse/react-slingshot

• Webpack
• NPM as a build tool (no Gulp, Grunt or Bower)
• React with Redux
• ESLint
• the list is long. Go and explore!

Your questions:

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

• Everything belongs in package.json now

• Dependencies required for build are in "devDependencies" i.e. npm install require-dir --save-dev (--save-dev updates your package.json by adding an entry to devDependencies)

• Dependencies required for your application during runtime are in "dependencies" i.e. npm install lodash --save (--save updates your package.json by adding an entry to dependencies)

If that is the case, when should I ever install packages explicitly like that without adding them to the file that manages dependencies (apart from installing command line tools globally)?

Always. Just because of comfort. When you add a flag (--save-dev or --save) the file that manages deps (package.json) gets updated automatically. Don't waste time by editing dependencies in it manually. Shortcut for npm install --save-dev package-name is npm i -D package-name and shortcut for npm install --save package-name is npm i -S package-name

I had the same problem and I rename the "repository" folder on ".m2" (something like repositoryBkp the name is not important is just in case something goes wrong) and create a new "repository" folder, then I re run maven and all the project compile successfully

Now, the sh step supports returning stdout by supplying the parameter returnStdout.

// These should all be performed at the point where you've
// checked out your sources on the slave. A 'git' executable
// must be available.
// Most typical, if you're not cloning into a sub directory
gitCommit = sh(returnStdout: true, script: 'git rev-parse HEAD').trim()
// short SHA, possibly better for chat notifications, etc.
shortCommit = gitCommit.take(6)

See this example.

Using replace() with regular expressions is the most flexible/powerful. It's also the only way to globally replace every instance of a search pattern in JavaScript. The non-regex variant of replace() will only replace the first instance.

For example:

var str = "foo gar gaz";

// returns: "foo bar gaz"
str.replace('g', 'b');

// returns: "foo bar baz"
str = str.replace(/g/gi, 'b');

In the latter example, the trailing /gi indicates case-insensitivity and global replacement (meaning that not just the first instance should be replaced), which is what you typically want when you're replacing in strings.

To remove characters, use an empty string as the replacement:

var str = "foo bar baz";

// returns: "foo r z"
str.replace(/ba/gi, '');

it's well documented here:

https://cwiki.apache.org/confluence/display/TOMCAT/Connectors#Connectors-Q6

How do I bind to a specific ip address? - "Each Connector element allows an address property. See the HTTP Connector docs or the AJP Connector docs". And HTTP Connectors docs:

http://tomcat.apache.org/tomcat-7.0-doc/config/http.html

Standard Implementation -> address

"For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, this port will be used on all IP addresses associated with the server."

If you use auto-layout on iOS 6 you might also need to set the preferredMaxLayoutWidth property:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.textAlignment = NSTextAlignmentCenter;
button.titleLabel.preferredMaxLayoutWidth = button.frame.size.width;

You can used two way.

First Way:

Set android:inputType="textCapSentences" on your EditText.

Second Way:

When user enter the number you have to used text watcher and change small to capital letter.

edittext.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {            

    }
        @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                    int arg3) {             
    }
    @Override
    public void afterTextChanged(Editable et) {
          String s=et.toString();
      if(!s.equals(s.toUpperCase()))
      {
         s=s.toUpperCase();
         edittext.setText(s);
         edittext.setSelection(edittext.length()); //fix reverse texting
      }
    }
});  

Im my case the problem was that I cretead sertificates without entering any data in cli interface. When I regenerated cretificates and enetered all fields: City, State, etc all became fine.

 sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt

For v4.0.7 You can increase the height by overriding CSS classes like this example:

    .select2-container .select2-selection--single {
    height: 36px;
}

.select2-container--default .select2-selection--single .select2-selection__rendered {
    line-height: 36px;
}

.select2-container--default .select2-selection--single .select2-selection__arrow {
    height: 36px;
}

You could use the Morpha stemmer. UW has uploaded morpha stemmer to Maven central if you plan to use it from a Java application. There's a wrapper that makes it much easier to use. You just need to add it as a dependency and use the edu.washington.cs.knowitall.morpha.MorphaStemmer class. Instances are threadsafe (the original JFlex had class fields for local variables unnecessarily). Instantiate a class and run morpha and the word you want to stem.

new MorphaStemmer().morpha("climbed") // goes to "climb"

No. Go to database tools (for 2007) and click checkmark on the Message Bar. Then, after the message bar apears, click on Options, and then Enable. Hope this helps.

Sometimes it may happen that there are multiple schema created in a database.

So to be specific schema we need to target, so this will help to do it.

SELECT count(*) into @colCnt FROM information_schema.columns WHERE table_name = 'mytable' AND column_name = 'mycolumn' and table_schema = DATABASE();
IF @colCnt = 0 THEN
    ALTER TABLE `mytable` ADD COLUMN `mycolumn` VARCHAR(20) DEFAULT NULL;
END IF;

just check if any unnecessary Jars are added in your library or not. if yes, then simply remove that jars from your library and clean your project once. Its worked for me.

ES6 Update:

As the first answer mentions, with ES6/Babel, you can now create multi-line strings simply by using backticks:

const htmlString = `Say hello to 
multi-line
strings!`;

Interpolating variables is a popular new feature that comes with back-tick delimited strings:

const htmlString = `${user.name} liked your post about strings`;

This just transpiles down to concatenation:

user.name + ' liked your post about strings'

Original ES5 answer:

Google's JavaScript style guide recommends to use string concatenation instead of escaping newlines:

Do not do this:

var myString = 'A rather long string of English text, an error message \
                actually that just keeps going and going -- an error \
                message to make the Energizer bunny blush (right through \
                those Schwarzenegger shades)! Where was I? Oh yes, \
                you\'ve got an error and all the extraneous whitespace is \
                just gravy.  Have a nice day.';

The whitespace at the beginning of each line can't be safely stripped at compile time; whitespace after the slash will result in tricky errors; and while most script engines support this, it is not part of ECMAScript.

Use string concatenation instead:

var myString = 'A rather long string of English text, an error message ' +
               'actually that just keeps going and going -- an error ' +
               'message to make the Energizer bunny blush (right through ' +
               'those Schwarzenegger shades)! Where was I? Oh yes, ' +
               'you\'ve got an error and all the extraneous whitespace is ' +
               'just gravy.  Have a nice day.';

I'd do this:

1. add the dependency as you like in your pom:

   <dependency>
           <groupId>com.stackoverflow...</groupId>
           <artifactId>artifactId...</artifactId>
           <version>1.0</version>
   </dependency>
   

2. run mvn install it will try to download the jar and fail. On the process, it will give you the complete command of installing the jar with the error message. Copy that command and run it! easy huh?!

Just use CSS to hide the content you do not want printed. When the user selects print - the page will look to the " media="print" CSS for instructions about the layout of the page.

The media="print" CSS has instructions to hide the content that we do not want printed.

<!-- CSS for the things we want to print (print view) -->
<style type="text/css" media="print">

#SCREEN_VIEW_CONTAINER{
        display: none;
    }
.other_print_layout{
        background-color:#FFF;
    }
</style>

<!-- CSS for the things we DO NOT want to print (web view) -->
<style type="text/css" media="screen">

   #PRINT_VIEW{
      display: none;
   }
.other_web_layout{
        background-color:#E0E0E0;
    }
</style>

<div id="SCREEN_VIEW_CONTAINER">
     the stuff I DO NOT want printed is here and will be hidden - 
     and not printed when the user selects print.
</div>

<div id="PRINT_VIEW">
     the stuff I DO want printed is here.
</div>

Just write:

date("Y") // A full numeric representation of a year, 4 digits
          // Examples: 1999 or 2003

Or:

date("y"); // A two digit representation of a year     Examples: 99 or 03

And 'echo' this value...

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

You can use #define as an alternative solution, which do not introduce vector and malloc, and you are still using the same syntax when defining an array.

#define row 8
#define col 8

int main()
{
int array_name[row][col];
}
