You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

Short post-Git-2 answer

I know this question has been out here for quite a while. And the answer from CB Bailey is 100% correct: git show-ref --tags --abbrev

I like this one better since it uses git tag:

git tag --list --format '%(refname:short) %(objectname:short)'

Simple. Short.

PS alias it as git taglist with this command:

git config --global alias.taglist "tag --list --format '%(refname:short) %(objectname:short)'"

As of Dec 2019:

Before answering this question let me say, I tried almost all the answers here on SO and from different forums but couldn't find a solution that works for all modern browsers and IE11.

So here is the solution I found, and I believe it's not yet discussed or mentioned in this post.

According to Mozilla Dev Network(MDN) post about how to turn off form autocomplete

By default, browsers remember information that the user submits through fields on websites. This enables the browser to offer autocompletion (that is, suggest possible completions for fields that the user has started typing in) or autofill (that is, pre-populate certain fields upon load)

On same article they discussed the usage of autocmplete property and its limitation. As we know, not all browsers honor this attribute as we desire.

Solution

So at the end of the article they shared a solution that works for all browsers including IE11+Edge. It is basically a jQuery plugin that do the trick. Here is the link to jQuery plugin and how it works.

Code snippet:

$(document).ready(function () {        
    $('#frmLogin').disableAutoFill({
        passwordField: '.password'
    });
});

Point to notice in HTML is that password field is of type text and password class is applied to identify that field:

<input id="Password" name="Password" type="text" class="form-control password">

Hope this would help someone.

Why so complicated?

Just check System Objects in Access-Options/Current Database/Navigation Options/Show System Objects

Open Table "MSysIMEXSpecs" and change according to your needs - its easy to read...

        var colors = new Dictionary < string, string > ();

I think the best option is to update Phpmyadmin to a version which has this already fixed.

Until it is published as a deb, you could do it like in @crimson-501 answer which I will copy below:

• Your first step is to install PMA (phpMyAdmin) from the official Ubuntu repo: apt-get install phpmyadmin.
• Next, cd into usr/share directory: cd /usr/share.
• Third, remove the phpmyadmin directory: rm -rf phpmyadmin.
• Now we need to download the latest PMA version onto our system (Note that you need wget: apt-get install wget): wget -P /usr/share/ "https://files.phpmyadmin.net/phpMyAdmin/4.9.4/phpMyAdmin-4.9.4-english.zip" Let me explain the arguments of this command, -P defines the path and "the link.zip" is currently (7/17/18) the latest version of PMA. You can find those links HERE.
• For this next step you need unzip (apt-get install unzip): unzip phpMyAdmin-4.9.4-english.zip. We just unzipped PMA, now we will move it to it's final home.
• Lets use the cp (copy) command to move our files! Note that we have to add the -r argument since this is a folder. cp -r phpMyAdmin-4.9.4-english phpmyadmin.
• Now it's time to clean up: rm -rf phpMyAdmin-4.9.4-english.

Keep Reading!

You might now notice two errors after you log into PMA.

the configuration file now needs a secret passphrase (blowfish_secret). phpmyadmin
The $cfg['TempDir'] (./tmp/) is not accessible. phpMyAdmin is not able to cache templates and will be slow because of this.

However, these issues are relatively easy to fix. For the first issue all you have to do is grab your editor of choice and edit /usr/share/phpmyadmin/config.inc.php but there's a problem, we removed it! That's ok, all you have to do is: cd /usr/share/phpmyadmin & cp config.sample.inc.php config.inc.php.

• We will now add our Blowfish Secret! nano config.inc.php and copy the dynamically generated secret from near the bottom of this page: https://www.question-defense.com/tools/phpmyadmin-blowfish-secret-generator.

Example phpMyAdmin Blowfish Secret Variable Entry:

/*
 * This is needed for cookie based authentication to encrypt password in
 * cookie
 */
$cfg['blowfish_secret'] = '{^QP+-(3mlHy+Gd~FE3mN{gIATs^1lX+T=KVYv{ubK*U0V'; 
/* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

Now save and close the file.

• Now we will create a tmp directory for PMA: mkdir tmp & chown -R www-data:www-data /usr/share/phpmyadmin/tmp. The last command allows the Apache web server to own the tmp directory and edit it's contents.

MS's query explaining the use of the KILL command is quite useful providing connection's information:

SELECT conn.session_id, host_name, program_name,
    nt_domain, login_name, connect_time, last_request_end_time 
FROM sys.dm_exec_sessions AS sess
JOIN sys.dm_exec_connections AS conn
   ON sess.session_id = conn.session_id;

I'm using this one:

  internal static bool IsValidJson(string data)
  {
     data = data.Trim();
     try
     {
        if (data.StartsWith("{") && data.EndsWith("}"))
        {
           JToken.Parse(data);
        }
        else if (data.StartsWith("[") && data.EndsWith("]"))
        {
           JArray.Parse(data);
        }
        else
        {
           return false;
        }
        return true;
     }
     catch
     {
        return false;
     }
  }

The print function in python adds itself \n

You could use

import sys
sys.stdout.write(a)

instead

Assuming that you didn't set a precision initially, it's assumed to be the maximum (38). You're reducing the precision because you're changing it from 38 to 14.

The easiest way to handle this is to rename the column, copy the data over, then drop the original column:

alter table EVAPP_FEES rename column AMOUNT to AMOUNT_OLD;

alter table EVAPP_FEES add AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_OLD;

alter table EVAPP_FEES drop column AMOUNT_OLD;

If you really want to retain the column ordering, you can move the data twice instead:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

import os
print os.getcwd()  # Prints the current working directory

To set the working directory:

os.chdir('c:\\Users\\uname\\desktop\\python')  # Provide the new path here

Here is what I did, hope it is helpful to anyone else :

Steps:

1. Stop your services that are using mongodb
2. Stop mongod - my way of doing this was with my rc file /etc/rc.d/rc.mongod stop, if you use something else, like systemd you should check your documentation how to do that
3. Create a new directory on the fresh harddisk - mkdir /mnt/database
4. Make sure that mongodb has privileges to read / write from that directory ( usually chown mongodb:mongodb -R /mnt/database/mongodb ) - thanks @DanailGabenski.
5. Copy the data folder of your mongodb to the new location - cp -R /var/lib/mongodb/ /mnt/database/
6. Remove the old database folder - rm -rf /var/lib/mongodb/
7. Create symbolic link to the new database folder - ln -s /mnt/database/mongodb /var/lib/mongodb
8. Start mongod - /etc/rc.d/rc.mongod start
9. Check the log of your mongod and do some sanity checking ( try mongo to connect to your database to see if everything is all right )
10. Start your services that you stopped in point 1

There is no need to tell that you should be careful when you do this, especialy with rm -rf but I think this is the best way to do it.

You should never try to copy database dir while mongod is running, because there might be services that write / read from it which will change the content of your database.

I see so many overcomplicated answers here and people always tell me that I tend to overcomplicate things. Also using IsAssignableFrom method for the purpose of solving OP problem is wrong!

Here is my example, it selects all assemblies from the app domain, then it takes flat list of all available types and checks every single type's list of interfaces for match:

public static IEnumerable<Type> GetImplementingTypes(this Type itype) 
    => AppDomain.CurrentDomain.GetAssemblies().SelectMany(s => s.GetTypes())
           .Where(t => t.GetInterfaces().Contains(itype));

The code below reads for any text files available in the directory which contains the script we are running. Then it opens every text file and stores the words of the text line into a list. After store the words we print each word line by line

import os, fnmatch

listOfFiles = os.listdir('.')
pattern = "*.txt"
store = []
for entry in listOfFiles:
    if fnmatch.fnmatch(entry, pattern):
        _fileName = open(entry,"r")
        if _fileName.mode == "r":
            content = _fileName.read()
            contentList = content.split(" ")
            for i in contentList:
                if i != '\n' and i != "\r\n":
                    store.append(i)

for i in store:
    print(i)

$("#theDiv").append("<img id='theImg' src='theImg.png'/>");

You need to read the documentation here.

man page of strcat says that arg1 and arg2 are appended to arg1.. and returns the pointer of s1. If you dont want disturb str1,str2 then you have write your own function.

char * my_strcat(const char * str1, const char * str2)
{
   char * ret = malloc(strlen(str1)+strlen(str2));

   if(ret!=NULL)
   {
     sprintf(ret, "%s%s", str1, str2);
     return ret;
   }
   return NULL;    
}

Hope this solves your purpose

Sometimes a BEFORE trigger can be replaced with an AFTER one, but this doesn't appear to be the case in your situation, for you clearly need to provide a value before the insert takes place. So, for that purpose, the closest functionality would seem to be the INSTEAD OF trigger one, as @marc_s has suggested in his comment.

Note, however, that, as the names of these two trigger types suggest, there's a fundamental difference between a BEFORE trigger and an INSTEAD OF one. While in both cases the trigger is executed at the time when the action determined by the statement that's invoked the trigger hasn't taken place, in case of the INSTEAD OF trigger the action is never supposed to take place at all. The real action that you need to be done must be done by the trigger itself. This is very unlike the BEFORE trigger functionality, where the statement is always due to execute, unless, of course, you explicitly roll it back.

But there's one other issue to address actually. As your Oracle script reveals, the trigger you need to convert uses another feature unsupported by SQL Server, which is that of FOR EACH ROW. There are no per-row triggers in SQL Server either, only per-statement ones. That means that you need to always keep in mind that the inserted data are a row set, not just a single row. That adds more complexity, although that'll probably conclude the list of things you need to account for.

So, it's really two things to solve then:

• replace the BEFORE functionality;

• replace the FOR EACH ROW functionality.

My attempt at solving these is below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  INSERT INTO sub (super_id)
  SELECT super_id FROM @new_super;
END;

This is how the above works:

1. The same number of rows as being inserted into sub1 is first added to super. The generated super_id values are stored in a temporary storage (a table variable called @new_super).

2. The newly inserted super_ids are now inserted into sub1.

Nothing too difficult really, but the above will only work if you have no other columns in sub1 than those you've specified in your question. If there are other columns, the above trigger will need to be a bit more complex.

The problem is to assign the new super_ids to every inserted row individually. One way to implement the mapping could be like below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    rownum   int IDENTITY (1, 1),
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  WITH enumerated AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS rownum
    FROM inserted
  )
  INSERT INTO sub1 (super_id, other columns)
  SELECT n.super_id, i.other columns
  FROM enumerated AS i
  INNER JOIN @new_super AS n
  ON i.rownum = n.rownum;
END;

As you can see, an IDENTIY(1,1) column is added to @new_user, so the temporarily inserted super_id values will additionally be enumerated starting from 1. To provide the mapping between the new super_ids and the new data rows, the ROW_NUMBER function is used to enumerate the INSERTED rows as well. As a result, every row in the INSERTED set can now be linked to a single super_id and thus complemented to a full data row to be inserted into sub1.

Note that the order in which the new super_ids are inserted may not match the order in which they are assigned. I considered that a no-issue. All the new super rows generated are identical save for the IDs. So, all you need here is just to take one new super_id per new sub1 row.

If, however, the logic of inserting into super is more complex and for some reason you need to remember precisely which new super_id has been generated for which new sub row, you'll probably want to consider the mapping method discussed in this Stack Overflow question:

• Using merge..output to get mapping between source.id and target.id

This would be helpful

button.titleLabel.font = [UIFont fontWithName:@"YOUR FONTNAME" size:12.0f]

You could use Range.Rows, Range.Columns or Range.Cells. Each of these collections contain Range objects.

Here's how you could modify Dick's example so as to work with Rows:

Sub LoopRange()

    Dim rCell As Range
    Dim rRng As Range

    Set rRng = Sheet1.Range("A1:A6")

    For Each rCell In rRng.Rows
        Debug.Print rCell.Address, rCell.Value
    Next rCell

End Sub

And Columns:

Sub LoopRange()

    Dim rCell As Range
    Dim rRng As Range

    Set rRng = Sheet1.Range("A1:A6")

    For Each rCol In rRng.Columns
        For Each rCell In rCol.Rows
            Debug.Print rCell.Address, rCell.Value
        Next rCell
    Next rCol

End Sub

There is something called ksweb:

https://play.google.com/store/apps/details?id=ru.kslabs.ksweb&feature=search_result

Using Streams and Lambda:

newIntegerlist = listName.stream().map(x-> 
    Integer.valueOf(x)).collect(Collectors.toList());

The above line of code will convert the List of type List<String> to List<Integer>.

I hope it was helpful.

f-string formatting:

This was new in Python 3.6 - the string is placed in quotation marks as usual, prepended with f'... in the same way you would r'... for a raw string. Then you place whatever you want to put within your string, variables, numbers, inside braces f'some string text with a {variable} or {number} within that text' - and Python evaluates as with previous string formatting methods, except that this method is much more readable.

>>> foobar = 3.141592
>>> print(f'My number is {foobar:.2f} - look at the nice rounding!')

My number is 3.14 - look at the nice rounding!

You can see in this example we format with decimal places in similar fashion to previous string formatting methods.

NB foobar can be an number, variable, or even an expression eg f'{3*my_func(3.14):02f}'.

Going forward, with new code I prefer f-strings over common %s or str.format() methods as f-strings can be far more readable, and are often much faster.

As @Agam said,

You need this statement in your driver file: from AthleteList import AtheleteList

write a cloud function to and update the node count.

// below function to get the given node count.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.userscount = functions.database.ref('/users/')
    .onWrite(event => {

      console.log('users number : ', event.data.numChildren());


      return event.data.ref.parent.child('count/users').set(event.data.numChildren());
    }); 

Refer :https://firebase.google.com/docs/functions/database-events

root--| |-users ( this node contains all users list) |
|-count |-userscount : (this node added dynamically by cloud function with the user count)

I have recently discovered that minidlna doesn't update the database if the media file is a hardlink. If you want these files to show up in the database, a full rescan is necessary.

ex: If you have a file /home/movies/foo.mkv and a hardlink in /home/minidlna/video/foo.mkv, where '/home/minidlna' is your minidlna share, you will have to do a rescan till that file appears in the db (and subsequently your dlna client).

I'm still trying to find a way around this. If anyone has any input, it's most welcome.

For anyone still coming to this post, the other option is to simply omit the parentheses:

Sub SomeOtherSub(Stattyp As String)
    'Daty and the other variables are defined here

    CatSubProduktAreakum Stattyp, Daty + UBound(SubCategories) + 2

End Sub

The Call keywords is only really in VBA for backwards compatibilty and isn't actually required.

If however, you decide to use the Call keyword, then you have to change your syntax to suit.

'// With Call
Call Foo(Bar)

'// Without Call
Foo Bar

Both will do exactly the same thing.

That being said, there may be instances to watch out for where using parentheses unnecessarily will cause things to be evaluated where you didn't intend them to be (as parentheses do this in VBA) so with that in mind the better option is probably to omit the Call keyword and the parentheses

Mark Cidade's answer is right - you need to supply a tuple.

However from Python 2.6 onwards you can use format instead of %:

'{0} in {1}'.format(unicode(self.author,'utf-8'),  unicode(self.publication,'utf-8'))

Usage of % for formatting strings is no longer encouraged.

This method of string formatting is the new standard in Python 3.0, and should be preferred to the % formatting described in String Formatting Operations in new code.

First zip or gzip the folders:
Use the following command:

zip -r NameYouWantForZipFile.zip foldertozip/

or

tar -pvczf BackUpDirectory.tar.gz /path/to/directory

for gzip compression use SCP:

scp [email protected]:~/serverpath/public_html ~/Desktop

You can use

string extension = System.IO.Path.GetExtension(filename);

And then remove the extension manually:

string result = filename.Substring(0, filename.Length - extension.Length);

Here is an example of accessing the ith index of a std::vector using an std::iterator within a loop which does not require incrementing two iterators.

std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
    int ith = it - strs.begin();
    if(ith == nth) {
        printf("Iterator within  a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
    }
}

Without a for-loop

it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());

and using at method:

printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());

Yes, use @import

You can also use ISNULL and a select statement to get this result

SELECT

ISNULL((SELECT 'TRUE' FROM TABLE2 WHERE TABLE2.ID = TABEL1.ID),'FALSE') AS columName,
etc
FROM TABLE1

To answer the first:

UPDATE Orders SET Quantity = Quantity + 1 WHERE ...

To answer the second:

There are several ways to do this. Since you did not specify a database, I will assume MySQL.

1. INSERT INTO table SET x=1, y=2 ON DUPLICATE KEY UPDATE x=x+1, y=y+2
2. REPLACE INTO table SET x=1, y=2

They both can handle your question. However, the first syntax allows for more flexibility to update the record rather than just replace it (as the second one does).

Keep in mind that for both to exist, there has to be a UNIQUE key defined...

In the collapse package recently released on CRAN, I have attempted to compress most of the common apply functionality into just 2 functions:

1. dapply (Data-Apply) applies functions to rows or (default) columns of matrices and data.frames and (default) returns an object of the same type and with the same attributes (unless the result of each computation is atomic and drop = TRUE). The performance is comparable to lapply for data.frame columns, and about 2x faster than apply for matrix rows or columns. Parallelism is available via mclapply (only for MAC).

Syntax:

dapply(X, FUN, ..., MARGIN = 2, parallel = FALSE, mc.cores = 1L, 
       return = c("same", "matrix", "data.frame"), drop = TRUE)

Examples:

# Apply to columns:
dapply(mtcars, log)
dapply(mtcars, sum)
dapply(mtcars, quantile)
# Apply to rows:
dapply(mtcars, sum, MARGIN = 1)
dapply(mtcars, quantile, MARGIN = 1)
# Return as matrix:
dapply(mtcars, quantile, return = "matrix")
dapply(mtcars, quantile, MARGIN = 1, return = "matrix")
# Same for matrices ...

2. BY is a S3 generic for split-apply-combine computing with vector, matrix and data.frame method. It is significantly faster than tapply, by and aggregate (an also faster than plyr, on large data dplyr is faster though).

Syntax:

BY(X, g, FUN, ..., use.g.names = TRUE, sort = TRUE,
   expand.wide = FALSE, parallel = FALSE, mc.cores = 1L,
   return = c("same", "matrix", "data.frame", "list"))

Examples:

# Vectors:
BY(iris$Sepal.Length, iris$Species, sum)
BY(iris$Sepal.Length, iris$Species, quantile)
BY(iris$Sepal.Length, iris$Species, quantile, expand.wide = TRUE) # This returns a matrix 
# Data.frames
BY(iris[-5], iris$Species, sum)
BY(iris[-5], iris$Species, quantile)
BY(iris[-5], iris$Species, quantile, expand.wide = TRUE) # This returns a wider data.frame
BY(iris[-5], iris$Species, quantile, return = "matrix") # This returns a matrix
# Same for matrices ...

Lists of grouping variables can also be supplied to g.

Talking about performance: A main goal of collapse is to foster high-performance programming in R and to move beyond split-apply-combine alltogether. For this purpose the package has a full set of C++ based fast generic functions: fmean, fmedian, fmode, fsum, fprod, fsd, fvar, fmin, fmax, ffirst, flast, fNobs, fNdistinct, fscale, fbetween, fwithin, fHDbetween, fHDwithin, flag, fdiff and fgrowth. They perform grouped computations in a single pass through the data (i.e. no splitting and recombining).

Syntax:

fFUN(x, g = NULL, [w = NULL,] TRA = NULL, [na.rm = TRUE,] use.g.names = TRUE, drop = TRUE)

Examples:

v <- iris$Sepal.Length
f <- iris$Species

# Vectors
fmean(v)             # mean
fmean(v, f)          # grouped mean
fsd(v, f)            # grouped standard deviation
fsd(v, f, TRA = "/") # grouped scaling
fscale(v, f)         # grouped standardizing (scaling and centering)
fwithin(v, f)        # grouped demeaning

w <- abs(rnorm(nrow(iris)))
fmean(v, w = w)      # Weighted mean
fmean(v, f, w)       # Weighted grouped mean
fsd(v, f, w)         # Weighted grouped standard-deviation
fsd(v, f, w, "/")    # Weighted grouped scaling
fscale(v, f, w)      # Weighted grouped standardizing
fwithin(v, f, w)     # Weighted grouped demeaning

# Same using data.frames...
fmean(iris[-5], f)                # grouped mean
fscale(iris[-5], f)               # grouped standardizing
fwithin(iris[-5], f)              # grouped demeaning

# Same with matrices ...

In the package vignettes I provide benchmarks. Programming with the fast functions is significantly faster than programming with dplyr or data.table, especially on smaller data, but also on large data.

If it is a form try changing the header to:

headers[ "Content-type" ] = "application/x-www-form-urlencoded; charset=utf-8";

and if it is not a form and a simple json then try this header:

headers[ "Content-type" ] = "application/json";

If it's a huuge array and it would take too much memory to serialize it to a string before writing, you can use streams:

var fs = require('fs');

var file = fs.createWriteStream('array.txt');
file.on('error', function(err) { /* error handling */ });
arr.forEach(function(v) { file.write(v.join(', ') + '\n'); });
file.end();

The Java way is that you should consider what data abstraction most suits your needs. Remember that in Java a List is an abstract, not a concrete data type. You should declare the strings as a List, and then initialize it using the ArrayList implementation.

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

This separation of Abstract Data Type and specific implementation is one the key aspects of object oriented programming.

An ArrayList implements the List Abstract Data Type using an array as its underlying implementation. Access speed is virtually identical to an array, with the additional advantages of being able to add and subtract elements to a List (although this is an O(n) operation with an ArrayList) and that if you decide to change the underlying implementation later on you can. For example, if you realize you need synchronized access, you can change the implementation to a Vector without rewriting all your code.

In fact, the ArrayList was specifically designed to replace the low-level array construct in most contexts. If Java was being designed today, it's entirely possible that arrays would have been left out altogether in favor of the ArrayList construct.

Since arrays keep all the data in a contiguous chunk of memory (unlike Lists), would the use of an array to store thousands of strings cause problems ?

In Java, all collections store only references to objects, not the objects themselves. Both arrays and ArrayList will store a few thousand references in a contiguous array, so they are essentially identical. You can consider that a contiguous block of a few thousand 32-bit references will always be readily available on modern hardware. This does not guarantee that you will not run out of memory altogether, of course, just that the contiguous block of memory requirement is not difficult to fufil.

Do not use Bitmap.Config.ARGB_8888

Instead use int w = WIDTH_PX, h = HEIGHT_PX;

Bitmap.Config conf = Bitmap.Config.ARGB_4444; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);

// ready to draw on that bitmap through that canvas

ARGB_8888 can land you in OutOfMemory issues when dealing with more bitmaps or large bitmaps. Or better yet, try avoiding usage of ARGB option itself.

The other methods work fine, but you can also use the good old django.shortcut.redirect.

The code below was taken from this answer.

In Django 2.x:

from django.shortcuts import redirect
from django.urls import path, include

urlpatterns = [
    # this example uses named URL 'hola-home' from app named hola
    # for more redirect's usage options: https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
    path('', lambda request: redirect('hola/', permanent=True)),
    path('hola/', include('hola.urls')),
]

Oh I found it in the PHP manual.

foreach ($array as $key => $value){
    statement
}

The current element's key will be assigned to the variable $key on each loop.

Use 'index'.

def GetMorseCode(letter):
   index = letterList.index(letter)
   code = codeList[index]
   return code

Of course, you'll want to validate your input letter (convert its case as necessary, make sure it's in the list in the first place by checking that index != -1), but that should get you down the path.

I think you can get it using subc1.text.

>>> html = """
<p>
    <strong class="offender">YOB:</strong> 1987<br />

    <strong class="offender">HEIGHT:</strong> 5'05''<br />

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(html)
>>> print soup.text


YOB: 1987
RACE: WHITE
GENDER: FEMALE
HEIGHT: 5'05''
WEIGHT: 118
EYE COLOR: GREEN
HAIR COLOR: BROWN

Or if you want to explore it, you can use .contents :

>>> p = soup.find('p')
>>> from pprint import pprint
>>> pprint(p.contents)
[u'\n',
 <strong class="offender">YOB:</strong>,
 u' 1987',
 <br/>,

 <strong class="offender">EYE COLOR:</strong>,
 u' GREEN',
 <br/>,
 u'\n',
 <strong class="offender">HAIR COLOR:</strong>,
 u' BROWN',
 <br/>,
 u'\n']

and filter out the necessary items from the list:

>>> data = dict(zip([x.text for x in p.contents[1::4]], [x.strip() for x in p.contents[2::4]]))
>>> pprint(data)
{u'EYE COLOR:': u'GREEN',
 u'GENDER:': u'FEMALE',

 u'HEIGHT:': u"5'05''",
 u'RACE:': u'WHITE',
 u'WEIGHT:': u'118',
 u'YOB:': u'1987'}

This is a pretty old question, but perhaps this answer can still help someone else.

You can emulate a public constant that is restricted within a class scope by applying the final keyword to a method that returns a pre-defined value, like this:

class Foo {

    // This is a private constant
    final public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

The final keyword on a method prevents an extending class from re-defining the method. You can also place the final keyword in front of the class declaration, in which case the keyword prevents class Inheritance.

To get nearly exactly what Alex was looking for the following code can be used:

final class Constants {

    public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

class Foo {

    static public app()
    {
        return new Constants();
    }
}

The emulated constant value would be accessible like this:

Foo::app()->MYCONSTANT();

First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).

Neither is supported by Windows command-line ftp.exe. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.

Using WinSCP, your batch file would look like (for SFTP):

echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat

And the batch file:

winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%

Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP% syntax), the batch file simplifies to:

winscp.com /log=ftpcmd.log /command ^
    "open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

For the purpose of -hostkey switch, see verifying the host key in script.

Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:

All you need to tweak is the source file name (use the %TIMESTAMP% syntax as shown previously) and the path to the log file.

For FTPS, replace the sftp:// in the open command with ftpes:// (explicit TLS/SSL) or ftps:// (implicit TLS/SSL). Remove the -hostkey switch.

winscp.com /log=ftpcmd.log /command ^
    "open ftps://ftp_user:[email protected] -explicit" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

You may need to add the -certificate switch, if your server's certificate is not issued by a trusted authority.

Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.

See a complete conversion guide from ftp.exe to WinSCP.

You should also read the Guide to automating file transfers to FTP server or SFTP server.

Note to using %TIMESTAMP#yyyymmdd% instead of %date%: A format of %date% variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date% resolves to ct 06. 11. 2014, what might be problematic when used as a part of a file name.

For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd% resolves to 20170515 on any locale.

If you are using Azure DevOps MSBuild task the error may be caused by doubled configuration flag. Please make sure you put $(BuildConfiguration) in specified box instead of MSBuild Arguments one:

You can export the private key with the command-line tool from GPG. It works on the Windows-shell. Use the following command:

gpg --export-secret-keys

A normal export with --export will not include any private keys, therefore you have to use --export-secret-keys.

Edit:

To sum up the information given in my comments, this is the command that allows you to export a specific key with the ID 1234ABCD to the file secret.asc:

gpg --export-secret-keys --armor 1234ABCD > secret.asc

You can find the ID that you need using the following command. The ID is the second part of the second column:

gpg --list-keys

To Export just 1 specific secret key instead of all of them:

gpg --export-secret-keys keyIDNumber > exportedKeyFilename.asc

keyIDNumber is the number of the key id for the desired key you are trying to export.

Like Vito mentions, this error occurs after Java updates as the path:

C:\ProgramData\Oracle\Java\javapath

is added to the Path environment variable, causing Eclipse to run using the wrong java version.

To fix the problem:

1) Right-click on Computer and choose Properties.

2) Click Advanced system settings

3) Click Environment Variables...

4) Find the Path variable in the System variables section.

5) Choose it and click Edit...

6) Find and delete the above mentioned path.

This fixed it for me. I should mention that I already have the path:

c:\Program Files\Java\jdk1.7.0_21\bin

in the Path variable, but the new path was added to the beginning of the Path variable and therefore resolution would use that path first.

There isn't a need for _.map or _.pluck since ES6 has taken off.

Here's an alternative using ES6 JavaScript:

clips.map(clip => clip.id)

Ok I wonder when's the use but, here are two snipets you could use:

lastlog.cmd

@echo off
for /f "delims=" %%l in (log.txt) do set TimeStamp=%%l
echo %TimeStamp%

Change the "echo.." line, but the last log time is within %TimeStamp%. No temp files used, no clutter and reusable as it is in a variable.

On the other hand, if you need to know this WITHIN your code, and not from another batch, change your logging for:

set TimeStamp=%date%, %time%
echo %TimeStamp% >> log.txt

so that the variable %TimeStamp% is usable later when you need it.

Member functions that do not modify the class instance should be declared as const:

int getId() const {
    return id;
}
string getName() const {
    return name;
}

Anytime you see "discards qualifiers", it's talking about const or volatile.

$arr = array(1, 'a', 3, 4 => 1, 'b' => 1);
foreach ($arr as $key => $val) {
    echo "{$key} = {$val}" . (end(array_keys($arr))===$key ? '' : ', ');
}
// output: 0 = 1, 1 = a, 2 = 3, 4 = 1, b = 1

Laravel 5 uses .env file to configure your app. .env should not be committed on your repository, like github or bitbucket. On your local environment your .env will look like the following:

# .env
APP_ENV=local

For your production server, you might have the following config:

# .env
APP_ENV=production

In views with {{}} and/or ng-model, Angular is setting up $watch()es for you behind the scenes.

By default $watch compares by reference. If you set the third parameter to $watch to true, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:

$scope.$watch('myModel', function() { ... }, true);

Update: Angular v1.2 added a new method for this, `$watchCollection():

$scope.$watchCollection('myModel', function() { ... });

Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.

Check first your class loader.

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

if (classLoader == null) {
    classLoader = Class.class.getClassLoader();
}

classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");

// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

To fix your code you can simply change [Cov] to Cov.values, the first parameter of pd.DataFrame will become a multi-dimensional numpy array:

Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')

But the smartest solution still is use pd.read_excel with header=None and names=columns_list.

I think its not html target properties problem but you unchecked "open nw windows in a new tab instead" option in "tab" tab under firefox "options" menu. check it and try again.

However, avpicture_get_size is defined.

No, as the header (<libavcodec/avcodec.h>) just declares it.

The definition is in the library itself.

So you might like to add the linker option to link libavcodec when invoking gcc:

-lavcodec

Please also note that libraries need to be specified on the command line after the files needing them:

gcc -I$HOME/ffmpeg/include program.c -lavcodec

Not like this:

gcc -lavcodec -I$HOME/ffmpeg/include program.c

Referring to Wyzard's comment, the complete command might look like this:

gcc -I$HOME/ffmpeg/include program.c -L$HOME/ffmpeg/lib -lavcodec

For libraries not stored in the linkers standard location the option -L specifies an additional search path to lookup libraries specified using the -l option, that is libavcodec.x.y.z in this case.

For a detailed reference on GCC's linker option, please read here.

Use a correlated sub-query. Very simple, here you go:

SELECT 
somedate, 
(SELECT SUM(somevalue) FROM TestTable t2 WHERE t2.somedate<=t1.somedate) AS running_total
FROM TestTable t1
GROUP BY somedate
ORDER BY somedate

The code might not be exactly correct, but I'm sure that the idea is.

The GROUP BY is in case a date appears more than once, you would only want to see it once in the result set.

If you don't mind seeing repeating dates, or you want to see the original value and id, then the following is what you want:

SELECT 
id,
somedate, 
somevalue,
(SELECT SUM(somevalue) FROM TestTable t2 WHERE t2.somedate<=t1.somedate) AS running_total
FROM TestTable t1
ORDER BY somedate

The simplest and most reliable solution is inserting flex items at the right places. If they are wide enough (width: 100%), they will force a line break.

.container {_x000D_

.item:nth-child(4n - 1) {_x000D_
  background: silver;_x000D_
}_x000D_
.line-break {_x000D_
  width: 100%;_x000D_
}

<div class="container">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="line-break"></div>_x000D_

  <div class="item">9</div>_x000D_
  <div class="line-break"></div>_x000D_
  <div class="item">10</div>_x000D_
</div>

But that's ugly and not semantic. Instead, we could generate pseudo-elements inside the flex container, and use order to move them to the right places.

.container {_x000D_
  background: tomato;_x000D_
  display: flex;_x000D_

  order: 1;_x000D_
}_x000D_
.item:nth-child(n + 7) {_x000D_
  order: 2;_x000D_
}

<div class="container">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="item">4</div>_x000D_
  <div class="item">5</div>_x000D_
  <div class="item">6</div>_x000D_
  <div class="item">7</div>_x000D_
  <div class="item">8</div>_x000D_
  <div class="item">9</div>_x000D_
</div>

But there is a limitation: the flex container can only have a ::before and a ::after pseudo-element. That means you can only force 2 line breaks.

To solve that, you can generate the pseudo-elements inside the flex items instead of in the flex container. This way you won't be limited to 2. But those pseudo-elements won't be flex items, so they won't be able to force line breaks.

But luckily, CSS Display L3 has introduced display: contents (currently only supported by Firefox 37):

The element itself does not generate any boxes, but its children and pseudo-elements still generate boxes as normal. For the purposes of box generation and layout, the element must be treated as if it had been replaced with its children and pseudo-elements in the document tree.

So you can apply display: contents to the children of the flex container, and wrap the contents of each one inside an additional wrapper. Then, the flex items will be those additional wrappers and the pseudo-elements of the children.

Alternatively, according to Fragmenting Flex Layout and CSS Fragmentation, Flexbox allows forced breaks by using break-before, break-after or their CSS 2.1 aliases:

.item:nth-child(3n) {
  page-break-after: always; /* CSS 2.1 syntax */
  break-after: always; /* New syntax */
}

.container {_x000D_
  background: tomato;_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
  align-content: space-between;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.item {_x000D_
  width: 100px;_x000D_
  background: gold;_x000D_
  height: 100px;_x000D_
  border: 1px solid black;_x000D_
  font-size: 30px;_x000D_
  line-height: 100px;_x000D_
  text-align: center;_x000D_
  margin: 10px_x000D_
}_x000D_
.item:nth-child(3n) {_x000D_
  page-break-after: always;_x000D_
  background: silver;_x000D_
}

<div class="container">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="item">4</div>_x000D_
  <div class="item">5</div>_x000D_
  <div class="item">6</div>_x000D_
  <div class="item">7</div>_x000D_
  <div class="item">8</div>_x000D_
  <div class="item">9</div>_x000D_
  <div class="item">10</div>_x000D_
</div>

Forced line breaks in flexbox are not widely supported yet, but it works on Firefox.

After a power blackout, I ran into the database disk image is malformed error and the suggested reindex nodes command did not fix all issues due to violated constraints. Also the procedure described in http://mail-archives.apache.org/mod_mbox/subversion-users/201111.mbox/%[email protected]%3E did not resolve the problem.

Solution in my case:

• Checkout the svn repository again into a temporary folder
• Copy, i.e. replace, the file ".svn/wc.db" from the new checkout to the corrupt one

This may be useful, if your original svn checkout contains many modified or unversioned files and you don't want to switch to a fresh svn checkout.

try this:

$("table#myTable tr").last().after(data);

Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".

• When you run git remote add origin [email protected]:User/UserRepo.git, then a new remote created named origin.
• When you run git remote set-url origin [email protected]:User/UserRepo.git,git searches for existing remote having name origin and change it's remote repository url. If git unable to find any remote having name origin, It raise an error fatal: No such remote 'origin'.

If you are going to create a new repository then use git remote add origin [email protected]:User/UserRepo.git to add remote.

As per your requirement i have created a sample demo using Swift 4 in which you can encode/decode string and image as per your requirement.

• I have also added sample methods of relevant operations.

The real trick is: Use a Backslash at the end of the target path where to copy the file. The /Y is for overwriting existing files, if you want no warnings.

Example:

xcopy /Y "C:\file\from\here.txt" "C:\file\to\here\"

A couple of wires are crossed here. The various autoplay settings that you're working with only affect whether the SWF's root timeline starts out paused or not. So if your SWF had a timeline animation, or if it had an embedded video on the root timeline, then these settings would do what you're after.

However, the SWF you're working with almost certainly has only one frame on its timeline, so these settings won't affect playback at all. That one frame contains some flavor of video playback component, which contains ActionScript that controls how the video behaves. To get that player component to start of paused, you'll have to change the settings of the component itself.

Without knowing more about where the content came from it's hard to say more, but when one publishes from Flash, video player components normally include a parameter for whether to autoplay. If your SWF is being published by an application other than Flash (Captivate, I suppose, but I'm not up on that) then your best bet would be to check the settings for that app. Anyway it's not something you can control from the level of the HTML page. (Unless you were talking to the SWF from JavaScript, and for that to work the video component would have to be designed to allow it.)

To detect both positive and negative peaks, PeakDetect is helpful.

from peakdetect import peakdetect

peaks = peakdetect(data, lookahead=20) 
# Lookahead is the distance to look ahead from a peak to determine if it is the actual peak. 
# Change lookahead as necessary 
higherPeaks = np.array(peaks[0])
lowerPeaks = np.array(peaks[1])
plt.plot(data)
plt.plot(higherPeaks[:,0], higherPeaks[:,1], 'ro')
plt.plot(lowerPeaks[:,0], lowerPeaks[:,1], 'ko')

I think you could do something like this:

for ii in range(200):
    restart = False
    for jj in range(200, 400):
        ...block0...
        if something:
            restart = True
            break
    if restart:
        continue
    ...block1...

The json.load() method (without "s" in "load") can read a file directly:

import json
with open('strings.json') as f:
    d = json.load(f)
    print(d)

json.loads() method, which is used for string arguments only.

import json

person = '{"name": "Bob", "languages": ["English", "Fench"]}'
print(type(person))
# Output : <type 'str'>

person_dict = json.loads(person)
print( person_dict)
# Output: {'name': 'Bob', 'languages': ['English', 'Fench']}

print(type(person_dict))
# Output : <type 'dict'>

Here , we can see after using loads() takes a string ( type(str) ) as a input and return dictionary.

Consider breaking this problem up into two pieces:

1. filter out the items that match the given regular expression
2. determine if that filtered list has 0 matches in it

const sampleStringData = ["frog", "pig", "tiger"];

const matches = sampleStringData.filter((animal) => /any.regex.here/.test(animal));

if (matches.length === 0) {
  console.log("No matches");
}

Well I am bit late to answer,but my code is tested

check scheme from uri:

 byte[] videoBytes;

if (uri.getScheme().equals("content")){
        InputStream iStream =   context.getContentResolver().openInputStream(uri);
            videoBytes = getBytes(iStream);
        }else{
            File file = new File(uri.getPath());
            FileInputStream fileInputStream = new FileInputStream(file);     
            videoBytes = getBytes(fileInputStream);
        }

In the above answer I converted the video uri to bytes array , but that's not related to question, I just copied my full code to show the usage of FileInputStream and InputStream as both are working same in my code.

I used the variable context which is getActivity() in my Fragment and in Activity it simply be ActivityName.this

context=getActivity(); //in Fragment

context=ActivityName.this;// in activity

var str = "PER 343573";
var right6 = string.IsNullOrWhiteSpace(str) ? string.Empty 
             : str.Length < 6 ? str 
             : str.Substring(str.Length - 6); // "343573"
// alternative
var alt_right6 = new string(str.Reverse().Take(6).Reverse().ToArray()); // "343573"

this supports any number of character in the str. the alternative code not support null string. and, the first is faster and the second is more compact.

i prefer the second one if knowing the str containing short string. if it's long string the first one is more suitable.

e.g.

var str = "";
var right6 = string.IsNullOrWhiteSpace(str) ? string.Empty 
             : str.Length < 6 ? str 
             : str.Substring(str.Length - 6); // ""
// alternative
var alt_right6 = new string(str.Reverse().Take(6).Reverse().ToArray()); // ""

or

var str = "123";
var right6 = string.IsNullOrWhiteSpace(str) ? string.Empty 
             : str.Length < 6 ? str 
             : str.Substring(str.Length - 6); // "123"
// alternative
var alt_right6 = new string(str.Reverse().Take(6).Reverse().ToArray()); // "123"

Taken from this page:

"NaN" stands for "not a number". "Nan" is produced if a floating point operation has some input parameters that cause the operation to produce some undefined result. For example, 0.0 divided by 0.0 is arithmetically undefined. Taking the square root of a negative number is also undefined.

See this post: Breakpoints not working in Xcode?. You might be pushing "Run" instead of "Debug" in which case your program is not running with the help of gdb, in which case you cannot expect breakpoints to work!

If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to

grep token | cut -d, -f1 | cut -d\" -f4

as it is the part which is dealing with extracting the token from the response.

echo "Getting token response and extracting token"    
def token = sh (returnStdout: true, script: """
    curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()

After extracting the token you can use the token to make subsequent calls as follows.

echo "Token : ${token[-1]}"       
echo "Making calls using token..."       
curl -S -i -k  -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources 

this is very old question, but since I came here while searching worth putting my answer.

SELECT DATEPART(ISO_WEEK,'2020-11-13') AS ISO_8601_WeekNr

Use boolean rather than Boolean every time you can. This will avoid many NullPointerExceptions and make your code more robust.

Boolean is useful, for example

• to store booleans in a collection (List, Map, etc.)
• to represent a nullable boolean (coming from a nullable boolean column in a database, for example). The null value might mean "we don't know if it's true or false" in this context.
• each time a method needs an Object as argument, and you need to pass a boolean value. For example, when using reflection or methods like MessageFormat.format().

Executing easy. Getting the results can be hard.

Take a look at this question I asked Best way/tool to get the results from an oracle package procedure

The summary of it goes like this.

Assuming you had a Package named mypackage and procedure called getQuestions. It returns a refcursor and takes in string user name.

All you have to do is create new SQL File (file new). Set the connection and paste in the following and execute.

var r refcursor;
exec mypackage.getquestions(:r, 'OMG Ponies');
print r;

A JSON document basically consists of lists and dictionaries. There is no obvious way to map such a datastructure on a two-dimensional table.

An interesting fact.

I was sure TRUNCATE will always perform better, but in my case, for a db with approx 30 tables with foreign keys, populated with only a few rows, it took about 12 seconds to TRUNCATE all tables, as opposed to only a few hundred milliseconds to DELETE the rows. Setting the auto increment adds about a second in total, but it's still a lot better.

So I would suggest try both, see which works faster for your case.

Remember that you will need to connect to running docker container. So you probably want to use tcp instead of unix socket. Check output of docker ps command and look for running mysql containers. If you find one then use mysql command like this: mysql -h 127.0.0.1 -P <mysql_port> (you will find port in docker ps output). If you can't find any running mysql container in docker ps output then try docker images to find mysql image name and try something like this to run it: docker run -d -p 3306:3306 tutum/mysql where "tutum/mysql" is image name found in docker images.

std::div returns a structure with both result and remainder.

The finally block is always executed unless there is abnormal program termination, either resulting from a JVM crash or from a call to System.exit(0).

On top of that, any value returned from within the finally block will override the value returned prior to execution of the finally block, so be careful of checking all exit points when using try finally.

This should work on all browsers that support the onpaste event and the mutation observer.

This solution goes a step beyond getting the text only, it actually allows you to edit the pasted content before it get pasted into an element.

It works by using contenteditable, onpaste event (supported by all major browsers) en mutation observers (supported by Chrome, Firefox and IE11+)

step 1

Create a HTML-element with contenteditable

<div contenteditable="true" id="target_paste_element"></div>

step 2

In your Javascript code add the following event

document.getElementById("target_paste_element").addEventListener("paste", pasteEventVerifierEditor.bind(window, pasteCallBack), false);

We need to bind pasteCallBack, since the mutation observer will be called asynchronously.

step 3

Add the following function to your code

function pasteEventVerifierEditor(callback, e)
{
   //is fired on a paste event. 
    //pastes content into another contenteditable div, mutation observer observes this, content get pasted, dom tree is copied and can be referenced through call back.
    //create temp div
    //save the caret position.
    savedCaret = saveSelection(document.getElementById("target_paste_element"));

    var tempDiv = document.createElement("div");
    tempDiv.id = "id_tempDiv_paste_editor";
    //tempDiv.style.display = "none";
    document.body.appendChild(tempDiv);
    tempDiv.contentEditable = "true";

    tempDiv.focus();

    //we have to wait for the change to occur.
    //attach a mutation observer
    if (window['MutationObserver'])
    {
        //this is new functionality
        //observer is present in firefox/chrome and IE11
        // select the target node
        // create an observer instance
        tempDiv.observer = new MutationObserver(pasteMutationObserver.bind(window, callback));
        // configuration of the observer:
        var config = { attributes: false, childList: true, characterData: true, subtree: true };

        // pass in the target node, as well as the observer options
        tempDiv.observer.observe(tempDiv, config);

    }   

}



function pasteMutationObserver(callback)
{

    document.getElementById("id_tempDiv_paste_editor").observer.disconnect();
    delete document.getElementById("id_tempDiv_paste_editor").observer;

    if (callback)
    {
        //return the copied dom tree to the supplied callback.
        //copy to avoid closures.
        callback.apply(document.getElementById("id_tempDiv_paste_editor").cloneNode(true));
    }
    document.body.removeChild(document.getElementById("id_tempDiv_paste_editor"));

}

function pasteCallBack()
{
    //paste the content into the element.
    restoreSelection(document.getElementById("target_paste_element"), savedCaret);
    delete savedCaret;

    pasteHtmlAtCaret(this.innerHTML, false, true);
}

            if (selectPastedContent) {
                range.setStartBefore(firstNode);

What the code does:

1. Somebody fires the paste event by using ctrl-v, contextmenu or other means
2. In the paste event a new element with contenteditable is created (an element with contenteditable has elevated privileges)
3. The caret position of the target element is saved.
4. The focus is set to the new element
5. The content gets pasted into the new element and is rendered in the DOM.
6. The mutation observer catches this (it registers all changes to the dom tree and content). Then fires the mutation event.
7. The dom of the pasted content gets cloned into a variable and returned to the callback. The temporary element is destroyed.
8. The callback receives the cloned DOM. The caret is restored. You can edit this before you append it to your target. element. In this example I'm using Tim Downs functions for saving/restoring the caret and pasting HTML into the element.

Get the pasted content on document on paste event

I did it like this. For group named Editor.

# views.py
def index(request):
    current_user_groups = request.user.groups.values_list("name", flat=True)
    context = {
        "is_editor": "Editor" in current_user_groups,
    }
    return render(request, "index.html", context)

template

# index.html
{% if is_editor %}
  <h1>Editor tools</h1>
{% endif %}

If you want to manipulate the form programmatically the simplest solution is to keep a reference to it:

static Form myForm;

static void Main()
{
    myForm = new Form();
    Application.Run(myForm);
}

You can then use that to change the size (or what ever else you want to do) at run time. Though as Arrow points out you can't set the Width and Height directly but have to set the Size property.

I don't think you need ui-router at all for this. The documentation available for the $location service says in the first paragraph, "...changes to $location are reflected into the browser address bar." It continues on later to say, "What does it not do? It does not cause a full page reload when the browser URL is changed."

So, with that in mind, why not simply change the $location.path (as the method is both a getter and setter) with something like the following:

var newPath = IdFromService;
$location.path(newPath);

The documentation notes that the path should always begin with a forward slash, but this will add it if it's missing.

I had the same problem (with a version of git-recent) and discovered it was to do with color escape codes used by git. I wonder whether this could explain why this problem is occurring so commonly.

This is demonstrates what could be happening, though color is normally set in git configuration rather than the command line (otherwise it's effect would be obvious):

~/dev/trunk (master)$ git checkout `git branch -l  --color=always  | grep django-1.11`
error: pathspec 'django-1.11' did not match any file(s) known to git.
~/dev/trunk (master)$ git branch -l  --color=always  | grep django-1.11
  django-1.11
~/dev/trunk (master)$ git checkout `git branch -l  | grep django-1.11`
Switched to branch 'django-1.11'
Your branch is up-to-date with 'gerrit/django-1.11'.
~/dev/trunk (django-1.11)$ 

I figure a git config that doesn't play with the color settings should work color=auto should do the right thing. My particular issue was because the git recent I was using was defined as an alias with hard coded colors, and I was trying to build commands on top of that

Just for knowledge:

'http://api.livreto.co/books'.replace(/^(https?:\/\/)([a-z]{3}[0-9]?\.)?(\w+)(\.[a-zA-Z]{2,3})(\.[a-zA-Z]{2,3})?.*$/, '$3$4$5');

# returns livreto.co

Basically there are two CER certificate encoding types, DER and Base64. When type DER returns an error loading certificate (asn1 encoding routines), try the PEM and it shall work.

openssl x509 -inform DER -in certificate.cer -out certificate.crt

openssl x509 -inform PEM -in certificate.cer -out certificate.crt

properties have a specific meaning in Objective-C, but I think you mean something that's equivalent to a static variable? E.g. only one instance for all types of Foo?

To declare class functions in Objective-C you use the + prefix instead of - so your implementation would look something like:

// Foo.h
@interface Foo {
}

+ (NSDictionary *)dictionary;

// Foo.m
+ (NSDictionary *)dictionary {
  static NSDictionary *fooDict = nil;
  if (fooDict == nil) {
    // create dict
  }
  return fooDict;
}

var tableViewHeight: NSLayoutConstraint?

    tableViewHeight = NSLayoutConstraint(item: servicesTableView, 
    attribute: .height, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute,
    multiplier: 0.0, constant: 10)
    tableViewHeight?.isActive = true


  func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    tableViewHeight?.constant = tableView.contentSize.height
    tableView.layoutIfNeeded()
}

I've not tried this myself, but try setting:

height : 36px; //for other browsers
line-height: 36px; // for IE

Where 36px is the height of your input.

For those who recommended pyd3, it is no longer under active development and points you to vincent. vincent is also no longer under active development and recommends using altair.

So if you want a pythonic d3, use altair.

Try something like this:

with toupdate as (
    select p.*,
           (coalesce(max(interfaceid) over (), 0) +
            row_number() over (order by (select NULL))
           ) as newInterfaceId
    from prices
   )
update p
    set interfaceId = newInterfaceId
    where interfaceId is NULL

This doesn't quite make them consecutive, but it does assign new higher ids. To make them consecutive, try this:

with toupdate as (
    select p.*,
           (coalesce(max(interfaceid) over (), 0) +
            row_number() over (partition by interfaceId order by (select NULL))
           ) as newInterfaceId
    from prices
   )
update p
    set interfaceId = newInterfaceId
    where interfaceId is NULL

I also had a same requirement to delete an element from array which is in state.

const array= [...this.state.selectedOption]
const found= array.findIndex(x=>x.index===k)
if(found !== -1){
   this.setState({
   selectedOption:array.filter(x => x.index !== k)
    })
 }

First I copied the elements into an array. Then checked whether the element exist in the array or not. Then only I have deleted the element from the state using the filter option.

changed = (evt) => {    
this.isChecked = evt.target.checked;
}

<input type="checkbox" [checked]="checkbox" (change)="changed($event)" id="no"/>

There is a JDK socket tutorial here, which covers both the server and client end. That looks exactly like what you want.

(from that tutorial) This sets up to read from an echo server:

    echoSocket = new Socket("taranis", 7);
    out = new PrintWriter(echoSocket.getOutputStream(), true);
    in = new BufferedReader(new InputStreamReader(
                                echoSocket.getInputStream()));

taking a stream of bytes and converts to strings via the reader and using a default encoding (not advisable, normally).

Error handling and closing sockets/streams omitted from the above, but check the tutorial.

Here is some better usage of java for scanner

try(Scanner sc = new Scanner(System.in)) {

    //Use sc as you need

} catch (Exception e) {

        //  handle exception

}

seeing how the rules are fairly complicated, I'd suggest the following:

/^[a-z](\w*)[a-z0-9]$/i

match the whole string and capture intermediate characters. Then either with the string functions or the following regex:

/__/

check if the captured part has two underscores in a row. For example in Python it would look like this:

>>> import re
>>> def valid(s):
    match = re.match(r'^[a-z](\w*)[a-z0-9]$', s, re.I)
    if match is not None:
        return match.group(1).count('__') == 0
    return False

Complete the following steps in Eclipse to get plugins for JavaScript files:

1. Open Eclipse -> Go to "Help" -> "Install New Software"
2. Select the repository for your version of Eclipse. I have Juno so I selected http://download.eclipse.org/releases/juno
3. Expand "Programming Languages" -> Check the box next to "JavaScript Development Tools"
4. Click "Next" -> "Next" -> Accept the Terms of the License Agreement -> "Finish"
5. Wait for the software to install, then restart Eclipse (by clicking "Yes" button at pop up window)
6. Once Eclipse has restarted, open "Window" -> "Preferences" -> Expand "General" and "Editors" -> Click "File Associations" -> Add ".js" to the "File types:" list, if it is not already there
7. In the same "File Associations" dialog, click "Add" in the "Associated editors:" section
8. Select "Internal editors" radio at the top
9. Select "JavaScript Viewer". Click "OK" -> "OK"

To add JavaScript Perspective: (Optional)
10. Go to "Window" -> "Open Perspective" -> "Other..."
11. Select "JavaScript". Click "OK"

To open .html or .js file with highlighted JavaScript syntax:
12. (Optional) Select JavaScript Perspective
13. Browse and Select .html or .js file in Script Explorer in [JavaScript Perspective] (Or Package Explorer [Java Perspective] Or PyDev Package Explorer [PyDev Perspective] Don't matter.)
14. Right-click on .html or .js file -> "Open With" -> "Other..."
15. Select "Internal editors"
16. Select "Java Script Editor". Click "OK" (see JavaScript syntax is now highlighted )

If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.

 SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt


         try
            {
                File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
                //File root = new File(Environment.getExternalStorageDirectory(), "Notes");
                if (!root.exists()) 
                {
                    root.mkdirs();
                }
                File gpxfile = new File(root, fileName);


                FileWriter writer = new FileWriter(gpxfile,true);
                writer.append(sBody+"\n\n");
                writer.flush();
                writer.close();
                Toast.makeText(this, "Data has been written to Report File", Toast.LENGTH_SHORT).show();
            }
            catch(IOException e)
            {
                 e.printStackTrace();

            }

First of all, note you are not using the variable correctly:

if [ "pass_tc11" != "" ]; then
#     ^
#     missing $

Anyway, to check if a variable is empty or not you can use -z --> the string is empty:

if [ ! -z "$pass_tc11" ]; then
   echo "hi, I am not empty"
fi

or -n --> the length is non-zero:

if [ -n "$pass_tc11" ]; then
   echo "hi, I am not empty"
fi

From man test:

-z STRING

the length of STRING is zero

-n STRING

the length of STRING is nonzero

Samples:

$ [ ! -z "$var" ] && echo "yes"
$

$ var=""
$ [ ! -z "$var" ] && echo "yes"
$

$ var="a"
$ [ ! -z "$var" ] && echo "yes"
yes

$ var="a"
$ [ -n "$var" ] && echo "yes"
yes

To ignore all binary results from grep

grep -Ri "pattern" * | awk '{if($1 != "Binary") print $0}'

The awk part will filter out all the Binary file foo matches lines

I'd suggest <a href='page1.jsp'>Refresh</a>.

I was unable to use STRAGG because there is no way to DISTINCT and ORDER.

Performance scales linearly, which is good, since I am adding all columns of interest. The above took 3 seconds for 77K rows. For just one rollup, .172 seconds. I do with there was a way to distinctify multiple columns in a table in one pass.

If this is the bug with the edmx file located in a folder it is now fixed - download and install VS 2012 Update 1. You can get it from: http://www.microsoft.com/visualstudio/eng/downloads#d-visual-studio-2012-update

Do as below using String#tr :

 "((String1))".tr('()', '')
 # => "String1"

Wrap it in an unused function:

.f = function() {

## unwanted code here:

}

I aso find this extremely confusing. as @EricMartinez points out Renderer2 listen() returns the function to remove the listener:

ƒ () { return element.removeEventListener(eventName, /** @type {?} */ (handler), false); }

If i´m adding a listener

this.listenToClick = this.renderer.listen('document', 'click', (evt) => {
    alert('Clicking the document');
})

I´d expect my function to execute what i intended, not the total opposite which is remove the listener.

// I´d expect an alert('Clicking the document'); 
this.listenToClick();
// what you actually get is removing the listener, so nothing...

In the given scenario, It´d actually make to more sense to name it like:

// Add listeners
let unlistenGlobal = this.renderer.listen('document', 'click', (evt) => {
    console.log('Clicking the document', evt);
})

let removeSimple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
    console.log('Clicking the button', evt);
});

There must be a good reason for this but in my opinion it´s very misleading and not intuitive.

My solution, using a preprocessor define.

You should execute the command on every loop instead of building a huge command Text(btw,StringBuilder is made for this) The underlying Connection will not close and re-open for each loop, let the connection pool manager handle this. Have a look at this link for further informations: Tuning Up ADO.NET Connection Pooling in ASP.NET Applications

If you want to ensure that every command is executed successfully you can use a Transaction and Rollback if needed,

If you do not want changes in one list to effect another list try this.It worked for me
Hope this helps.

  public class MainClass {
  public static void main(String[] a) {

    List list = new ArrayList();
    list.add("A");

    List list2 = ((List) ((ArrayList) list).clone());

    System.out.println(list);
    System.out.println(list2);

    list.clear();

    System.out.println(list);
    System.out.println(list2);
  }
}

> Output:   
[A]  
[A]

You can use DISTINCT like that

mysql_query("SELECT DISTINCT(ticket_id), column1, column2, column3 
FROM temp_tickets 
ORDER BY ticket_id");

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

You can use the @ symbol in front of a string to form a verbatim string literal:

string query = @"SELECT foo, bar
FROM table
WHERE id = 42";

You also do not have to escape special characters when you use this method, except for double quotes as shown in Jon Skeet's answer.

A side from the very long complete accepted answer there is an important point to make about IndexOutOfRangeException compared with many other exception types, and that is:

Often there is complex program state that maybe difficult to have control over at a particular point in code e.g a DB connection goes down so data for an input cannot be retrieved etc... This kind of issue often results in an Exception of some kind that has to bubble up to a higher level because where it occurs has no way of dealing with it at that point.

IndexOutOfRangeException is generally different in that it in most cases it is pretty trivial to check for at the point where the exception is being raised. Generally this kind of exception get thrown by some code that could very easily deal with the issue at the place it is occurring - just by checking the actual length of the array. You don't want to 'fix' this by handling this exception higher up - but instead by ensuring its not thrown in the first instance - which in most cases is easy to do by checking the array length.

Another way of putting this is that other exceptions can arise due to genuine lack of control over input or program state BUT IndexOutOfRangeException more often than not is simply just pilot (programmer) error.

Set / change / reset the MySQL root password on Ubuntu Linux. Enter the following lines in your terminal.

1. Stop the MySQL Server: sudo /etc/init.d/mysql stop

2. Start the mysqld configuration: sudo mysqld --skip-grant-tables &

   In some cases, you've to create the /var/run/mysqld first:

   sudo mkdir -v /var/run/mysqld && sudo chown mysql /var/run/mysqld
   

3. Run: sudo service mysql start
4. Login to MySQL as root: mysql -u root mysql

5. Replace YOURNEWPASSWORD with your new password:

   UPDATE
     mysql.user
   SET
     Password = PASSWORD('YOURNEWPASSWORD')
   WHERE
     User = 'root';
   FLUSH PRIVILEGES;
   exit;
   

Note: on some versions, if password column doesn't exist, you may want to try:
UPDATE user SET authentication_string=password('YOURNEWPASSWORD') WHERE user='root';

Note: This method is not regarded as the most secure way of resetting the password, however, it works.

Why not using pyvmomi original function SmartConnectNoSSL. They added this function on June 14, 2016 and named it ConnectNoSSL, one day after they changed the name to SmartConnectNoSSL, use that instead of by passing the warning with unnecessary lines of code in your project?

Provides a standard method for connecting to a specified server without SSL verification. Useful when connecting to servers with self-signed certificates or when you wish to ignore SSL altogether

service_instance = connect.SmartConnectNoSSL(host=args.ip,
                                             user=args.user,
                                             pwd=args.password)

Only checked and checked="checked" are valid. Your other options depend on error recovery in browsers.

checked="yes" and checked="true" are particularly bad as they imply that checked="no" and checked="false" will set the default state to be unchecked … which they will not.

You may append HTML <br /> in between your lines. Something like:

MyLabel.Text = "SomeText asdfa asd fas df asdf" + "<br />" + "Some more text";

With StringBuilder you can try:

StringBuilder sb = new StringBuilder();
sb.AppendLine("Some text with line one");
sb.AppendLine("Some mpre text with line two");
MyLabel.Text = sb.ToString().Replace(Environment.NewLine, "<br />");

1. Add a new install project to your solution.
2. Add targets from all projects you want to be installed.
3. Configure pre-requirements and choose "Check for .NET 3.5 and SQL Express" option. Choose the location from where missing components must be installed.
4. Configure your installer settings - company name, version, copyright, etc.
5. Build and go!

I faced the same issue. Our application running on four application servers and due to invalid schema location mentioned on one of the web service WSDL, hung threads are generated on the servers . The appliucations got down frequently. After corrected the schema Location , the issue got resolved.

If your API level is 19+ you can use translation as above. If your API level is less than 19, you can take a look at similar tutorial: http://trickyandroid.com/fragments-translate-animation/

The font may exist with different names, and not at all on some systems, so you need to use different variations and fallback to get the closest possible look on all systems:

font-family: "Comic Sans MS", "Comic Sans", cursive;

Be careful what you use this font for, though. Many consider it as ugly and overused, so it should not be use for something that should look professional.

Simply, just replace , in your guideline tag

app:layout_constraintGuide_begin="291dp"

with

app:layout_constraintGuide_percent="0.7"

where 0.7 means 70%.

Also if you now try to drag guidelines, the dragged value will now show up in %age.

HTTP Basic + HTTPS is one common method.

The proper way is to look at the HTTP Accept-Language header sent to the server. This contains the ordered, weighted list of languages the user has configured their browser to prefer.

Unfortunately this header is not available for reading inside JavaScript; all you get is navigator.language, which tells you what localised version of the web browser was installed. This is not necessarily the same thing as the user's preferred language(s). On IE you instead get systemLanguage (OS installed language), browserLanguage (same as language) and userLanguage (user configured OS region), which are all similarly unhelpful.

If I had to choose between those properties, I'd sniff for userLanguage first, falling back to language and only after that (if those didn't match any available language) looking at browserLanguage and finally systemLanguage.

If you can put a server-side script somewhere else on the net that simply reads the Accept-Language header and spits it back out as a JavaScript file with the header value in the string, eg.:

var acceptLanguage= 'en-gb,en;q=0.7,de;q=0.3';

then you could include a <script src> pointing at that external service in the HTML, and use JavaScript to parse the language header. I don't know of any existing library code to do this, though, since Accept-Language parsing is almost always done on the server side.

Whatever you end up doing, you certainly need a user override because it will always guess wrong for some people. Often it's easiest to put the language setting in the URL (eg. http?://www.example.com/en/site vs http?://www.example.com/de/site), and let the user click links between the two. Sometimes you do want a single URL for both language versions, in which case you have to store the setting in cookies, but this may confuse user agents with no support for cookies and search engines.

I'll go into differences at the hardware level, on x86. This is mostly irrelevant unless you're writing a compiler or using assembly language. But it's nice to know.

Firstly, x86 has native support for the two's complement representation of signed numbers. You can use other representations but this would require more instructions and generally be a waste of processor time.

What do I mean by "native support"? Basically I mean that there are a set of instructions you use for unsigned numbers and another set that you use for signed numbers. Unsigned numbers can sit in the same registers as signed numbers, and indeed you can mix signed and unsigned instructions without worrying the processor. It's up to the compiler (or assembly programmer) to keep track of whether a number is signed or not, and use the appropriate instructions.

Firstly, two's complement numbers have the property that addition and subtraction is just the same as for unsigned numbers. It makes no difference whether the numbers are positive or negative. (So you just go ahead and ADD and SUB your numbers without a worry.)

The differences start to show when it comes to comparisons. x86 has a simple way of differentiating them: above/below indicates an unsigned comparison and greater/less than indicates a signed comparison. (E.g. JAE means "Jump if above or equal" and is unsigned.)

There are also two sets of multiplication and division instructions to deal with signed and unsigned integers.

Lastly: if you want to check for, say, overflow, you would do it differently for signed and for unsigned numbers.

Here is the good function for pre PHP 5: I added GMT difference at the end, it's not hardcoded.

function iso8601($time=false) {
    if ($time === false) $time = time();
    $date = date('Y-m-d\TH:i:sO', $time);
    return (substr($date, 0, strlen($date)-2).':'.substr($date, -2));
}

Object.toparams = function ObjecttoParams(obj) 
{
  var p = [];
  for (var key in obj) 
  {
    p.push(key + '=' + encodeURIComponent(obj[key]));
  }
  return p.join('&');
};

renamed some_project.workspace file to some_project.workspace.backup and ran $pod install. It created a new workspace file and the error went away.

Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:

*** Phones:

• HTC Sensation
• HTC Sensation XL
• HTC Evo 3D
• HTC One S
• HTC One X
• Huawei Ascend P1
• Huawei Ascend X (U9000)
• Huawei Honor (U8860)
• LG Nitro HD (P930)
• LG Optimus 2x (P990)
• LG Optimus Black (P970)
• LG Optimus 3D (P920)
• Samsung Galaxy S II (i9100)
• Samsung Galaxy S III (i9300)
• Samsung Galaxy R (i9103)
• Samsung Google Nexus S (i9020)
• Samsung Galaxy Nexus (i9250)
• Samsung Galaxy J3 (2017) model
• Samsung Galaxy Note (n7000)
• Sony Xperia P (LT22i)
• Sony Xperia S (LT26i)

*** Tablets:

• Acer Iconia Tab A100 (7")
• Acer Iconia Tab A500 (10.1")
• Asus Eee Pad Transformer (TF101)
• Asus Eee Pad Transformer Prime (TF201)

Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.

I'm resurrecting this because I was researching a non-JavaScript way to do this. I wasn't into the key handlers, and the CSS positioning stuff was causing tab ordering to break since CSS repositioning doesn't change tab order.

My solution is based on the response at https://stackoverflow.com/a/9491141.

The solution source is below. tabindex is used to correct tab behaviour of the hidden button, as well as aria-hidden to avoid having the button read out by screen readers / identified by assistive devices.

<form method="post" action="">
  <button type="submit" name="useraction" value="2nd" class="default-button-handler" aria-hidden="true" tabindex="-1"></button>
  <div class="form-group">
    <label for="test-input">Focus into this input: </label>
    <input type="text" id="test-input" class="form-control" name="test-input" placeholder="Focus in here and press enter / go" />
  </div>

1st button in DOM 2nd button in DOM 3rd button in DOM

Essential CSS for this solution:

.default-button-handler {
  width: 0;
  height: 0;
  padding: 0;
  border: 0;
  margin: 0;
}

Try setting host=127.0.0.1 on your db settings file, it worked for me! :)

Hope it helps!

The solution is actually described here: http://www.anujgakhar.com/2013/06/15/duplicates-in-a-repeater-are-not-allowed-in-angularjs/

AngularJS does not allow duplicates in a ng-repeat directive. This means if you are trying to do the following, you will get an error.

// This code throws the error "Duplicates in a repeater are not allowed.
// Repeater: row in [1,1,1] key: number:1"
<div ng-repeat="row in [1,1,1]">

However, changing the above code slightly to define an index to determine uniqueness as below will get it working again.

// This will work
<div ng-repeat="row in [1,1,1] track by $index">

Official docs are here: https://docs.angularjs.org/error/ngRepeat/dupes

Also, do you have another example (beside the Wikipedia one) where nullptr is superior to good old 0?

Yes. It's also a (simplified) real-world example that occurred in our production code. It only stood out because gcc was able to issue a warning when crosscompiling to a platform with different register width (still not sure exactly why only when crosscompiling from x86_64 to x86, warns warning: converting to non-pointer type 'int' from NULL):

Consider this code (C++03):

#include <iostream>

struct B {};

struct A
{
    operator B*() {return 0;}
    operator bool() {return true;}
};

int main()
{
    A a;
    B* pb = 0;
    typedef void* null_ptr_t;
    null_ptr_t null = 0;

    std::cout << "(a == pb): " << (a == pb) << std::endl;
    std::cout << "(a == 0): " << (a == 0) << std::endl; // no warning
    std::cout << "(a == NULL): " << (a == NULL) << std::endl; // warns sometimes
    std::cout << "(a == null): " << (a == null) << std::endl;
}

It yields this output:

(a == pb): 1
(a == 0): 0
(a == NULL): 0
(a == null): 1

Just to save you too much typos:

foreach($group_membership as $username){
        $username->items = array(additional array to add);
    }
    print_r($group_membership);

If you like it hacky and short you can also just update the labels

def update_xlabels(ax):
    xlabels = [format(label, ',.0f') for label in ax.get_xticks()]
    ax.set_xticklabels(xlabels)

update_xlabels(ax)
update_xlabels(ax2)

How is the __getattribute__ method used?

It is called before the normal dotted lookup. If it raises AttributeError, then we call __getattr__.

Use of this method is rather rare. There are only two definitions in the standard library:

$ grep -Erl  "def __getattribute__\(self" cpython/Lib | grep -v "/test/"
cpython/Lib/_threading_local.py
cpython/Lib/importlib/util.py

Best Practice

The proper way to programmatically control access to a single attribute is with property. Class D should be written as follows (with the setter and deleter optionally to replicate apparent intended behavior):

class D(object):
    def __init__(self):
        self.test2=21

    @property
    def test(self):
        return 0.

    @test.setter
    def test(self, value):
        '''dummy function to avoid AttributeError on setting property'''

    @test.deleter
    def test(self):
        '''dummy function to avoid AttributeError on deleting property'''

And usage:

>>> o = D()
>>> o.test
0.0
>>> o.test = 'foo'
>>> o.test
0.0
>>> del o.test
>>> o.test
0.0

A property is a data descriptor, thus it is the first thing looked for in the normal dotted lookup algorithm.

Options for __getattribute__

You several options if you absolutely need to implement lookup for every attribute via __getattribute__.

• raise AttributeError, causing __getattr__ to be called (if implemented)
• return something from it by
  • using super to call the parent (probably object's) implementation
  • calling __getattr__
  • implementing your own dotted lookup algorithm somehow

For example:

class NoisyAttributes(object):
    def __init__(self):
        self.test=20
        self.test2=21
    def __getattribute__(self, name):
        print('getting: ' + name)
        try:
            return super(NoisyAttributes, self).__getattribute__(name)
        except AttributeError:
            print('oh no, AttributeError caught and reraising')
            raise
    def __getattr__(self, name):
        """Called if __getattribute__ raises AttributeError"""
        return 'close but no ' + name    


>>> n = NoisyAttributes()
>>> nfoo = n.foo
getting: foo
oh no, AttributeError caught and reraising
>>> nfoo
'close but no foo'
>>> n.test
getting: test
20

What you originally wanted.

And this example shows how you might do what you originally wanted:

class D(object):
    def __init__(self):
        self.test=20
        self.test2=21
    def __getattribute__(self,name):
        if name=='test':
            return 0.
        else:
            return super(D, self).__getattribute__(name)

And will behave like this:

>>> o = D()
>>> o.test = 'foo'
>>> o.test
0.0
>>> del o.test
>>> o.test
0.0
>>> del o.test

Traceback (most recent call last):
  File "<pyshell#216>", line 1, in <module>
    del o.test
AttributeError: test

Code review

Your code with comments. You have a dotted lookup on self in __getattribute__. This is why you get a recursion error. You could check if name is "__dict__" and use super to workaround, but that doesn't cover __slots__. I'll leave that as an exercise to the reader.

class D(object):
    def __init__(self):
        self.test=20
        self.test2=21
    def __getattribute__(self,name):
        if name=='test':
            return 0.
        else:      #   v--- Dotted lookup on self in __getattribute__
            return self.__dict__[name]

>>> print D().test
0.0
>>> print D().test2
...

You probably need to change your mount command from:

[root@localhost Desktop]# sudo mount -t vboxsf D:\share_folder_vm \share_folder

to:

[root@localhost Desktop]# sudo mount -t vboxsf share_name \share_folder

where share_name is the "Name" of the share in the VirtualBox -> Shared Folders -> Folder List list box. The argument you have ("D:\share_folder_vm") is the "Path" of the share on the host, not the "Name".

You are running the [ (aka test) command with the argument "false", not running the command false. Since "false" is a non-empty string, the test command always succeeds. To actually run the command, drop the [ command.

if false; then
   echo "True"
else
   echo "False"
fi

Just add another variable.

int temp;
while (cin >> temp && V.size() < n){
    V.push_back(temp);
}

You can also use the following alternative realpath.

Create a file called path.php

Put the following code inside by specifying the name of the created file.

<?php 
    echo realpath('path.php'); 
?>

A php file that you can move to all your folders to always have the absolute path from where the executed file is located.

;-)

Try svn export instead of svn checkout. That works for single files.

The reason for the limitation is that checkout creates a working copy, that contains meta-information about repository, revision, attributes, etc. That metadata is stored in subdirectories named '.svn'. And single files don't have subdirectories.

    def __init__(self):
        self.var1 = 1
        self.var2 = 2
    def method(self):
        self.var1 = self.var1 + self.var2
        return self.var1

class ClassB(ClassA):
    def __init__(self):
        ClassA.__init__(self)

object1 = ClassA() 
sum = object1.method()  
object2 = ClassB() 
print sum

    DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
    System.out.println(LocalDate.parse("08/16/2011", dateFormatter));

Output:

2011-08-16

I am contributing the modern answer. The answer by Bohemian is correct and was a good answer when it was written 6 years ago. Now the notoriously troublesome SimpleDateFormat class is long outdated and we have so much better in java.time, the modern Java date and time API. I warmly recommend you use this instead of the old date-time classes.

What went wrong in your code?

When I parse 08/16/2011 using your snippet, I get Sun Jan 16 00:08:00 CET 2011. Since lowercase mm is for minutes, I get 00:08:00 (8 minutes past midnight), and since uppercase DD is for day of year, I get 16 January.

In java.time too format pattern strings are case sensitive, and we needed to use uppercase MM for month and lowercase dd for day of month.

Question: Can I use java.time with my Java version?

Yes, java.time works nicely on Java 6 and later and on both older and newer Android devices.

• In Java 8 and later and on new Android devices (from API level 26, I’m told) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the new classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

You can use the %p formatter. It's always best practice cast your pointer void* before printing.

The C standard says:

The argument shall be a pointer to void. The value of the pointer is converted to a sequence of printing characters, in an implementation-defined manner.

Here's how you do it:

printf("%p", (void*)p);

You can't decode a unicode, and you can't encode a str. Try doing it the other way around.

I had the same issue on windows 10, after trying all the previous solution the problem persists so I decided to uninstall my python 2.7 and install the version 2.7.13 and it works perfectly.

first of all, we have to make sure that you have downloaded and installed the JDK. In order to download it click on the following link

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

(Do not forget to check "Accept License Agreement", before you choose the version you want to download)

For Windows OS 32-Bit (x86) choose "jdk-8u77-windows-i586.exe"

For Windows OS 64-Bit (x64) choose "jdk-8u77-windows-x64.exe"

Install the file that is going to be downloaded. During the installation, pay attention, because you have to keep the installation path.

When you have done so, the last thing to do, is to define two "Environment Variables".

The first "Environmental Variable" name should be:

JAVA_HOME and its value should be the installation path

(for example: C:\Program Files\Java\jdk1.8.0_77)

The second "Environmental Variable" name should be:

JRE_HOME and its value should be the installation path

(for example C:\Program Files\Java\jre8)

As soon as you have defined the Environment Variables, you can go to command prompt (cdm) and run from every path your preferred "java.exe" commands. Your command line can now recognize your "java.exe" commands.

:)

P.S.: In order to define "Environment Variable", make a right click on "This PC" and select "properties" from the menu. Then the "System" window will appear and you have to click on "Advanced system settings". As a consequence "System properties" window shows. Select the "Advanced" tab and click on "Environment Variables" button. You can now define the aforementioned variables and you're done

I solved that problem by using a special setting for JsonSerializerSettings which is called TypeNameHandling.All

TypeNameHandling setting includes type information when serializing JSON and read type information so that the create types are created when deserializing JSON

Serialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var text = JsonConvert.SerializeObject(configuration, settings);

Deserialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var configuration = JsonConvert.DeserializeObject<YourClass>(json, settings);

The class YourClass might have any kind of base type fields and it will be serialized properly.

match_var = a==b

that should more than suffice

you cant use a - in a variable name as it thinks that is match (minus) var

match=1
var=2

print match-var  #prints -1

Using bits of answers from this question and the latest doc, I was able to extract my numerical arrays using

import h5py
with h5py.File(filename, 'r') as h5f:
    h5x = h5f[list(h5f.keys())[0]]['x'][()]

Where 'x' is simply the X coordinate in my case.

The parser is having trouble concatenating your string. Try this:

write-host 'value is : '$i' '$($ds.Tables[1].Rows[$i][0])

Edit: Using double quotes might also be clearer since you can include the expressions within the quoted string:

write-host "value is : $i $($ds.Tables[1].Rows[$i][0])"

My experience in August 2013 with a linux client and a simple AWS Beanstalk installation (single EC2 instance) is as follows (based on Community Wiki above)

Configure Security Group

1. In the AWS console, select EC2 to go to the EC2 Dashboard
2. Discover the security group to which your EC2 instance belongs by clicking Instances in the left hand panel and then selecting the instance you want to connect to (in my case there is only one - called Default Environment). The details are shown at the base of the page - You should see a field for Security Groups - make a note of the name - in my case "awsweb...".
3. From the left hand panel select Security Groups.
4. Select the awsweb... security group and the details should show at the base of the page
5. Select the Inbound tab and choose SSH from the "Create a New Rule" drop down. Insert the ip address/CIDR of your local machine (from which you intend to connect), e.g. 192.168.0.12/32 and click Add Rule and Apply Rule Changes.

Create Public-Private Key Pair

1. From the EC2 dashboard select Key Pairs from the left hand panel
2. Click Key Pair (at top) and enter a name such as myname-key-pair-myregion or whatever valid key name you like.
3. Confirm and then accept the download of the private key from the browser saving it for instance to your home directory or wherever you fancy. Make sure the directory only has write permissions for you.

Associate the Public Private Key Pair with the Elastic Beanstalk EC2 Server

1. To add a public-private key pair to an Elastic Beanstalk EC2 instance do: Services -> Elastic Beanstalk -> My App -> Default Environment takes you to the default environment (the one where you upload your app)
2. Click Configuration (on left hand panel) and then on the gear/cog associated with "Instances"
3. A page entitled "Server" is displayed
4. Select your prebuilt key par from EC2 Key Pair and do Save
5. Some warning message is displayed so do Save again.

Connect to AWS EC2 Instance using SSH

1. In a terminal session change to the directory containing your private key (.pem file).
2. If you've had a few goes at this you should probably do something about .ssh/known_hosts if you have one such as renaming it. Otherwise you may get an error about the host's identity having changed.
3. Do: ssh -i ./myname-key-pair-my-region.pem [email protected]

Good luck

Okay i might have some even different approach.

I am aware that it won't suit everybody but nontheless someone might find it useful.

For those who do not want to pupup a new window, and like me, are concerned about css styles this is what i came up with:

I wrapped view of my app into additional container, which is being hidden when printing and there is additional container for what needs to be printed which is shown when is printing.

Below working example:

var app = angular.module('myApp', []);_x000D_
 app.controller('myCtrl', function($scope) {_x000D_
  _x000D_
    $scope.people = [{_x000D_
      "id" : "000",_x000D_
      "name" : "alfred"_x000D_
    },_x000D_
    {_x000D_
      "id" : "020",_x000D_
      "name" : "robert"_x000D_
    },_x000D_
    {_x000D_
      "id" : "200",_x000D_
      "name" : "me"_x000D_
    }];_x000D_
_x000D_
    $scope.isPrinting = false;_x000D_
  $scope.printElement = {};_x000D_
  _x000D_
  $scope.printDiv = function(e)_x000D_
  {_x000D_
   console.log(e);_x000D_
   $scope.printElement = e;_x000D_
   _x000D_
   $scope.isPrinting = true;_x000D_
      _x000D_
      //does not seem to work without toimeouts_x000D_
   setTimeout(function(){_x000D_
    window.print();_x000D_
   },50);_x000D_
   _x000D_
   setTimeout(function(){_x000D_
    $scope.isPrinting = false;_x000D_
   },50);_x000D_
   _x000D_
   _x000D_
  };_x000D_
    _x000D_
  });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<div ng-app="myApp" ng-controller="myCtrl">_x000D_
_x000D_
 <div ng-show="isPrinting">_x000D_
  <p>Print me id: {{printElement.id}}</p>_x000D_
    <p>Print me name: {{printElement.name}}</p>_x000D_
 </div>_x000D_
 _x000D_
 <div ng-hide="isPrinting">_x000D_
    <!-- your actual application code -->_x000D_
    <div ng-repeat="person in people">_x000D_
      <div ng-click="printDiv(person)">Print {{person.name}}</div>_x000D_
    </div>_x000D_
  </div>_x000D_
  _x000D_
  _x000D_
</div>_x000D_
 

Note that i am aware that this is not an elegant solution, and it has several drawbacks, but it has some ups as well:

• does not need a popup window
• keeps the css intact
• does not store your whole page into a var (for whatever reason you don't want to do it)

Well, whoever you are reading this, have a nice day and keep coding :)

EDIT:

If it suits your situation you can actually use:

@media print  { .noprint  { display: none; } }
@media screen { .noscreen { visibility: hidden; position: absolute; } }

instead of angular booleans to select your printing and non printing content

EDIT:

Changed the screen css because it appears that display:none breaks printiing when printing first time after a page load/refresh.

visibility:hidden approach seem to be working so far.

netstat -ano | findstr :3010

taskkill /F /PID

But it won't work for me

then I tried taskkill -PID <processorid> -F

Example:- taskkill -PID 33192 -F Here 33192 is the processorid and it works

Code:

if(preg_match('/[^a-z_\-0-9]/i', $string))
{
  echo "not valid string";
}

Explanation:

• [] => character class definition
• ^ => negate the class
• a-z => chars from 'a' to 'z'
• _ => underscore
• - => hyphen '-' (You need to escape it)
• 0-9 => numbers (from zero to nine)

The 'i' modifier at the end of the regex is for 'case-insensitive' if you don't put that you will need to add the upper case characters in the code before by doing A-Z

Either u dont have permission to that schema/table OR table does exist. Mostly this issue occurred if you are using other schema tables in your stored procedures. Eg. If you are running Stored Procedure from user/schema ABC and in the same PL/SQL there are tables which is from user/schema XYZ. In this case ABC should have GRANT i.e. privileges of XYZ tables

Grant All On To ABC;

Select * From Dba_Tab_Privs Where Owner = 'XYZ'and Table_Name = <Table_Name>;

From the official GitHub site:

If you already have a file checked in, and you want to ignore it, Git will not ignore the file if you add a rule later. In those cases, you must untrack the file first, by running the following command in your terminal:

git rm --cached FILENAME

or

git rm --cached .

Update (9/1/15): The OP has made this question a bit of a moving target. It’s been updated again. So, I feel responsible to update my reply.

First, an answer to your provided example:

Yes, this is possible.

You can solve this by updating Child’s onClick to be this.props.onClick.bind(null, this):

var Child = React.createClass({
  render: function () {
    return <a onClick={this.props.onClick.bind(null, this)}>Click me</a>;
  }
});

The event handler in your Parent can then access the component and event like so:

  onClick: function (component, event) {
    // console.log(component, event);
  },

JSBin snapshot

But the question itself is misleading

Parent already knows Child’s props.

This isn’t clear in the provided example because no props are actually being provided. This sample code might better support the question being asked:

var Child = React.createClass({
  render: function () {
    return <a onClick={this.props.onClick}> {this.props.text} </a>;
  }
});

var Parent = React.createClass({
  getInitialState: function () {
    return { text: "Click here" };
  },
  onClick: function (event) {
    // event.component.props ?why is this not available? 
  },
  render: function() {
    return <Child onClick={this.onClick} text={this.state.text} />;
  }
});

It becomes much clearer in this example that you already know what the props of Child are.

JSBin snapshot

If it’s truly about using a Child’s props…

If it’s truly about using a Child’s props, you can avoid any hookup with Child altogether.

JSX has a spread attributes API I often use on components like Child. It takes all the props and applies them to a component. Child would look like this:

var Child = React.createClass({
  render: function () {
    return <a {...this.props}> {this.props.text} </a>;
  }
});

Allowing you to use the values directly in the Parent:

var Parent = React.createClass({
  getInitialState: function () {
    return { text: "Click here" };
  },
  onClick: function (text) {
    alert(text);
  },
  render: function() {
    return <Child onClick={this.onClick.bind(null, this.state.text)} text={this.state.text} />;
  }
});

JSBin snapshot

And there's no additional configuration required as you hookup additional Child components

var Parent = React.createClass({
  getInitialState: function () {
    return {
      text: "Click here",
      text2: "No, Click here",
    };
  },
  onClick: function (text) {
    alert(text);
  },
  render: function() {
    return <div>
      <Child onClick={this.onClick.bind(null, this.state.text)} text={this.state.text} />
      <Child onClick={this.onClick.bind(null, this.state.text2)} text={this.state.text2} />
    </div>;
  }
});

JSBin snapshot

But I suspect that’s not your actual use case. So let’s dig further…

A robust practical example

The generic nature of the provided example is a hard to talk about. I’ve created a component that demonstrations a practical use for the question above, implemented in a very Reacty way:

DTServiceCalculator working example
DTServiceCalculator repo

This component is a simple service calculator. You provide it with a list of services (with names and prices) and it will calculate a total the selected prices.

Children are blissfully ignorant

ServiceItem is the child-component in this example. It doesn’t have many opinions about the outside world. It requires a few props, one of which is a function to be called when clicked.

<div onClick={this.props.handleClick.bind(this.props.index)} />

It does nothing but to call the provided handleClick callback with the provided index[source].

Parents are Children

DTServicesCalculator is the parent-component is this example. It’s also a child. Let’s look.

DTServiceCalculator creates a list of child-component (ServiceItems) and provides them with props [source]. It’s the parent-component of ServiceItem but it`s the child-component of the component passing it the list. It doesn't own the data. So it again delegates handling of the component to its parent-component source

<ServiceItem chosen={chosen} index={i} key={id} price={price} name={name} onSelect={this.props.handleServiceItem} />

handleServiceItem captures the index, passed from the child, and provides it to its parent [source]

handleServiceClick (index) {
  this.props.onSelect(index);
}

Owners know everything

The concept of “Ownership” is an important one in React. I recommend reading more about it here.

In the example I’ve shown, I keep delegating handling of an event up the component tree until we get to the component that owns the state.

When we finally get there, we handle the state selection/deselection like so [source]:

handleSelect (index) {
  let services = […this.state.services];
  services[index].chosen = (services[index].chosen) ? false : true;
  this.setState({ services: services });
}

Conclusion

Try keeping your outer-most components as opaque as possible. Strive to make sure that they have very few preferences about how a parent-component might choose to implement them.

Keep aware of who owns the data you are manipulating. In most cases, you will need to delegate event handling up the tree to the component that owns that state.

Aside: The Flux pattern is a good way to reduce this type of necessary hookup in apps.

If you don't have an id on the image but have a parent div this is also a technique you can use.

<div id="myDiv"><img src="http://www.example.com/image.png"></div>

var myVar = document.querySelectorAll('#myDiv img')[0].src

You can use either File.Copy(oldFilePath, newFilePath) method or other way is, read file using StreamReader into an string and then use StreamWriter to write the file to destination location.

Your code might look like this :

StreamReader reader = new StreamReader("C:\foo.txt");
string fileContent = reader.ReadToEnd();

StreamWriter writer = new StreamWriter("D:\bar.txt");
writer.Write(fileContent);

You can add exception handling code...

A character in Java is a Unicode code-unit which is treated as an unsigned number. So if you perform c = (char)b the value you get is 2^16 - 56 or 65536 - 56.

Or more precisely, the byte is first converted to a signed integer with the value 0xFFFFFFC8 using sign extension in a widening conversion. This in turn is then narrowed down to 0xFFC8 when casting to a char, which translates to the positive number 65480.

From the language specification:

5.1.4. Widening and Narrowing Primitive Conversion

First, the byte is converted to an int via widening primitive conversion (§5.1.2), and then the resulting int is converted to a char by narrowing primitive conversion (§5.1.3).

To get the right point use char c = (char) (b & 0xFF) which first converts the byte value of b to the positive integer 200 by using a mask, zeroing the top 24 bits after conversion: 0xFFFFFFC8 becomes 0x000000C8 or the positive number 200 in decimals.

Above is a direct explanation of what happens during conversion between the byte, int and char primitive types.

If you want to encode/decode characters from bytes, use Charset, CharsetEncoder, CharsetDecoder or one of the convenience methods such as new String(byte[] bytes, Charset charset) or String#toBytes(Charset charset). You can get the character set (such as UTF-8 or Windows-1252) from StandardCharsets.

Also, in your html, remember to delete all blanks / line feeds / tabs between the closing tag and the opening tag.

<img src='a.png' /> <img src='b.png' /> will always display a space between the images even if the border attribute is set to 0, whereas <img src='a.png' /><img src='b.png' /> will not.

time.time() will do the job.

import time

start = time.time()
# run your code
end = time.time()

elapsed = end - start

You may want to look at this question, but I don't think it will be necessary.

Try using Sublime Package Control to install your packages.

Also take a look at these tips

Let's take a look at what happens when you select a file and submit your form (I've truncated the headers for brevity):

POST /upload?upload_progress_id=12344 HTTP/1.1
Host: localhost:3000
Content-Length: 1325
Origin: http://localhost:3000
... other headers ...
Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryePkpFF7tjBAqx29L

------WebKitFormBoundaryePkpFF7tjBAqx29L
Content-Disposition: form-data; name="MAX_FILE_SIZE"

100000
------WebKitFormBoundaryePkpFF7tjBAqx29L
Content-Disposition: form-data; name="uploadedfile"; filename="hello.o"
Content-Type: application/x-object

... contents of file goes here ...
------WebKitFormBoundaryePkpFF7tjBAqx29L--

NOTE: each boundary string must be prefixed with an extra --, just like in the end of the last boundary string. The example above already includes this, but it can be easy to miss. See comment by @Andreas below.

Instead of URL encoding the form parameters, the form parameters (including the file data) are sent as sections in a multipart document in the body of the request.

In the example above, you can see the input MAX_FILE_SIZE with the value set in the form, as well as a section containing the file data. The file name is part of the Content-Disposition header.

best way is

 button.setBackgroundResource(android.R.drawable.ic_delete);

OR this for Drawable left and something like that for right etc.

int imgResource = R.drawable.left_img;
button.setCompoundDrawablesWithIntrinsicBounds(imgResource, 0, 0, 0);

and

getResources().getDrawable() is now deprecated

You should be aware that you should avoid file I/O from within Linux kernel when possible. The main idea is to go "one level deeper" and call VFS level functions instead of the syscall handler directly:

Includes:

#include <linux/fs.h>
#include <asm/segment.h>
#include <asm/uaccess.h>
#include <linux/buffer_head.h>

Opening a file (similar to open):

struct file *file_open(const char *path, int flags, int rights) 
{
    struct file *filp = NULL;
    mm_segment_t oldfs;
    int err = 0;

    oldfs = get_fs();
    set_fs(get_ds());
    filp = filp_open(path, flags, rights);
    set_fs(oldfs);
    if (IS_ERR(filp)) {
        err = PTR_ERR(filp);
        return NULL;
    }
    return filp;
}

Close a file (similar to close):

void file_close(struct file *file) 
{
    filp_close(file, NULL);
}

Reading data from a file (similar to pread):

int file_read(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_read(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}   

Writing data to a file (similar to pwrite):

int file_write(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_write(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}

Syncing changes a file (similar to fsync):

int file_sync(struct file *file) 
{
    vfs_fsync(file, 0);
    return 0;
}

[Edit] Originally, I proposed using file_fsync, which is gone in newer kernel versions. Thanks to the poor guy suggesting the change, but whose change was rejected. The edit was rejected before I could review it.

Try this:

Project -> Properties -> Java Build Path -> Add Class Folder.

If it doesnt work, please be specific in what way your compilation fails, specifically post the error messages Eclipse returns, and i will know what to do about it.

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

In lightsail a virtual machine, SSD-based storage, data transfer, DNS management, and a static IP are all offered as a package. Whereas in normal case you provision an EC2 instance and then setup the rest of these things.Also Bandwidth included in the price, no security groups to set up, no need to worry about EBS volumes sizing.

Python 3 (and 2)

import base64
a = 'eW91ciB0ZXh0'
base64.b64decode(a)

Python 2

A quick way to decode it without importing anything:

'eW91ciB0ZXh0'.decode('base64')

or more descriptive

>>> a = 'eW91ciB0ZXh0'
>>> a.decode('base64')
'your text'

HttpServerUtility.UrlEncode will use HttpUtility.UrlEncode internally. There is no specific difference. The reason for existence of Server.UrlEncode is compatibility with classic ASP.

Another way -

Add these lines to your application config file configuration section:

<system.net>
    <settings>
        <servicePointManager expect100Continue="false" />
    </settings>
</system.net>

dynamic_cast should do the trick

TYPE& dynamic_cast<TYPE&> (object);
TYPE* dynamic_cast<TYPE*> (object);

The dynamic_cast keyword casts a datum from one pointer or reference type to another, performing a runtime check to ensure the validity of the cast.

If you attempt to cast to pointer to a type that is not a type of actual object, the result of the cast will be NULL. If you attempt to cast to reference to a type that is not a type of actual object, the cast will throw a bad_cast exception.

Make sure there is at least one virtual function in Base class to make dynamic_cast work.

Wikipedia topic Run-time type information

RTTI is available only for classes that are polymorphic, which means they have at least one virtual method. In practice, this is not a limitation because base classes must have a virtual destructor to allow objects of derived classes to perform proper cleanup if they are deleted from a base pointer.

I just wrote my own sleep which called the Win32 Sleep API function.

You can just implement a user-defined type like the following:

type Nullable<T> = T | undefined | null;

var foo: Nullable<number> = 10; // ok
var bar: Nullable<number> = true; // type 'true' is not assignable to type 'Nullable<number>'
var baz: Nullable<number> = null; // ok

var arr1: Nullable<Array<number>> = [1,2]; // ok
var obj: Nullable<Object> = {}; // ok

 // Type 'number[]' is not assignable to type 'string[]'. 
 // Type 'number' is not assignable to type 'string'
var arr2: Nullable<Array<string>> = [1,2];

As of October 2016, Google has added a file upload question type in native Google Forms, no Google Apps Script needed. See documentation.

You will get this way also.

  String getMonthForInt(int num) {
        String month = "wrong";
        DateFormatSymbols dfs = new DateFormatSymbols();
        String[] months = dfs.getMonths();
        if (num >= 0 && num <= 11 ) {
            month = months[num];
        }
        return month;
    }

Experienced this issue when trying to run the android emulator with Meteor 1.0 on elementary OS Luna (based on Ubuntu 12.04 LTS sources).

openjdk-6-jdk was installed, as well as the jre. In the end, not expecting any success, I tried:

sudo apt-get remove openjdk-6-*

this resulted in fully expected errors, so I followed up with

sudo apt-get install openjdk-6-jdk

and things worked. Go figure.

i like this clever syntax to do async work from an entrypoint

void async function main() {
  await doSomeWork()
  await doMoreWork()
}()
