It also can be used for creating scopes for Example:

class LoggerScope:IDisposable {
   static ThreadLocal<LoggerScope> threadScope = 
        new ThreadLocal<LoggerScope>();
   private LoggerScope previous;

   public static LoggerScope Current=> threadScope.Value;

   public bool WithTime{get;}

   public LoggerScope(bool withTime){
       previous = threadScope.Value;
       threadScope.Value = this;
       WithTime=withTime;
   }

   public void Dispose(){
       threadScope.Value = previous;
   }
}


class Program {
   public static void Main(params string[] args){
       new Program().Run();
   }

   public void Run(){
      log("something happend!");
      using(new LoggerScope(false)){
          log("the quick brown fox jumps over the lazy dog!");
          using(new LoggerScope(true)){
              log("nested scope!");
          }
      }
   }

   void log(string message){
      if(LoggerScope.Current!=null){
          Console.WriteLine(message);
          if(LoggerScope.Current.WithTime){
             Console.WriteLine(DateTime.Now);
          }
      }
   }

}

Using calls Dispose() after the using-block is left, even if the code throws an exception.

So you usually use using for classes that require cleaning up after them, like IO.

So, this using block:

using (MyClass mine = new MyClass())
{
  mine.Action();
}

would do the same as:

MyClass mine = new MyClass();
try
{
  mine.Action();
}
finally
{
  if (mine != null)
    mine.Dispose();
}

Using using is way shorter and easier to read.

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

Bootstrap 3 has its own class for this called:

hidden-print

It is defined like this:

@media print {
  .hidden-print {
    display: none !important;
  }
}

You do not have to define it on your own.

In Bootstrap 4 this has changed to:

.d-print-none

SIMPLEST ANSWER

just spread the set inside []

let mySet = new Set()
mySet.add(1)
mySet.add(5)
mySet.add(5) 
let arr = [...mySet ]

Result: [1,5]

Try this

 $(function(){
   $("input[type='number']").prop('min',1);
   $("input[type='number']").prop('max',10);
});

Demo

An object behaves like a dictionary because Javascript is dynamically typed, allowing you to add or remove properties at any time.

But Map() is much better because it:

• Provides get, set, has, and delete methods.
• Accepts any type for the keys instead of just strings.
• Provides an iterator for easy for-of usage and maintains order of results.
• Doesn't have edge cases with prototypes and other properties showing up during iteration or copying.
• Supports millions of items.
• Is very fast.

If you need a dictionary then you should just use a Map().

However, if you're only using string-based keys and need maximum read performance, then objects might be a better choice. This is because Javascript engines compile objects down to C++ classes in the background. The access path for properties on these classes is very optimized and much faster than a function call for Map().get().

These classes are also cached, so creating a new object with the same exact properties means the engine will reuse an existing background class. Adding or removing a property causes the shape of the class to change and the backing class to be re-compiled, which is why using an object as a dictionary with lots of additions and deletions is very slow, but reads of existing keys without changing the object are very fast.

So if you have a write-once read-heavy workload with string keys then you can use an object as a high-performance dictionary, but for everything else use a Map().

An easy way to do this is using the pandas library like this.

import pandas as pd
fields = ['star_name', 'ra']

df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print df.keys()
# See content in 'star_name'
print df.star_name

The problem here was the skipinitialspace which remove the spaces in the header. So ' star_name' becomes 'star_name'

Note that most of XLConnect's functions are already vectorized. This means that you can read in all worksheets with one function call without having to do explicit vectorization:

require(XLConnect)
wb <- loadWorkbook(system.file("demoFiles/mtcars.xlsx", package = "XLConnect"))
lst = readWorksheet(wb, sheet = getSheets(wb))

With XLConnect 0.2-0 lst will already be a named list.

While this can't be achieved with CSS/HTML alone, it can be achieved with JavaScript (without need of a library):

var textareas = document.getElementsByTagName('textarea');

for (i=0;i<textareas.length;i++){
    // you can omit the 'if' if you want to style the parent node regardless of its
    // element type
    if (textareas[i].parentNode.tagName.toString().toLowerCase() == 'div') {
        textareas[i].onfocus = function(){
            this.parentNode.style.borderStyle = 'solid';
        }
        textareas[i].onblur = function(){
            this.parentNode.style.borderStyle = 'dashed';
        }
    }
}

JS Fiddle demo.

Incidentally, with a library, such as jQuery, the above could be condensed down to:

$('textarea').focus(
    function(){
        $(this).parent('div').css('border-style','solid');
    }).blur(
    function(){
        $(this).parent('div').css('border-style','dashed');
    });

JS Fiddle demo.

References:

• getElementsByTagName().
• onfocus.
• onblur.
• parentNode.
• tagName.
• toString().
• toLowerCase().
• style.
• focus().
• blur().
• parent().
• css().

Well, once you have your font, you can invoke deriveFont. For example,

helvetica = helvetica.deriveFont(Font.BOLD, 12f);

Changes the font's style to bold and its size to 12 points.

The issue with my designer was 32 vs 64 bit issue. I could add the control to tool box after following the instructions in Cannot add Controls from 64-bit Assemblies to the Toolbox or Use in Designers Within the Visual Studio IDE MS KB article.

One of the comments mentioned using the GitHub GUI, but it didn't give any specific help on using and notice that most if not all the answers were useful at the command prompt only.

If you want to use the GitHub GUI, you can follow these steps:

1. Click the "+" button and choose "Add Local Repository"
2. Navigate to the directory with your existing code and click the "Add" button.
3. You should now be prompted to "Create a new local Git repository here" so click the "Yes" button.
4. Add your "Commit Summary" and "Extended description" as desired. By default, all of your files should selected with checkmarks already. Click the "Commit & Sync" button.
5. Now you will be prompted to add the name and description of your project as well as which account to push it to (if you have multiple). Click the "Push Repository" button

After a moment with a spinning GitHub icon, your source code will belong to a local repository and pushed/synchronised with a remote repository on your GitHub account. All of this is presuming you've previously set up the GitHub GUI, your GitHub account, and SSH keys.

Tested and worked in IE, Firefox, Chrome, Safari and Opera. I did not test IE6. The outer text-align is needed for IE. Other browsers (and IE9?) will work when you give the DIV margin (left and right) value of auto. Margin "0 auto" is a shorthand for margin "0 auto 0 auto" (top right bottom left).

Note: the text is also centered inside the inner DIV, if you want it to remain on the left side just specify text-align: left; for the inner DIV.

Edit: IE 6, 7, 8 and 9 running on the Standards Mode will work with margins set to auto.

SET out_number=SQRT(input_number); 

Instead of this write:

select SQRT(input_number); 

Please don't write SET out_number and your input parameter should be:

PROCEDURE `test`.`my_sqrt`(IN input_number INT, OUT out_number FLOAT) 

Try this:

Dim strFile As String = "yourfile.txt"

For those arriving here after updating phpunit to version 6 or greater released on 2017-02-03 (e.g. with composer), you may be getting this error because phpunit code is now namespaced (check changelog).

You will need to refactor things like \PHPUnit_Framework_TestCase to \PHPUnit\Framework\TestCase

int orientation = this.getResources().getConfiguration().orientation;
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
    // code for portrait mode
} else {
    // code for landscape mode
}

When the superclass of this is Context

see below code it may help you.

String q = "SELECT * FROM customer";
Cursor mCursor = mDb.rawQuery(q, null);

or

String q = "SELECT * FROM customer WHERE _id = " + customerDbId  ;
Cursor mCursor = mDb.rawQuery(q, null);

You can create your own extension method to do this:

public static bool Contains(this string source, string toCheck, StringComparison comp)
  {
    return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
  }

And then call:

 mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);

Use Process.Start to start a process.

    //
    Process.Start("C:\\process.exe");
    }
} 

The accepted answer has a couple of shortcomings:

• Don't target IDs in your JavaScript code. Use classes and data attributes to avoid repeating your code.
• It is good practice to hide with CSS on load rather than with JavaScript—to support non-JavaScript users, and prevent a show-hide flicker on load.

Considering the above, your options could even have different values, but toggle the same class:

<select class="div-toggle" data-target=".my-info-1">
  <option value="orange" data-show=".citrus">Orange</option>
  <option value="lemon" data-show=".citrus">Lemon</option>
  <option value="apple" data-show=".pome">Apple</option>
  <option value="pear" data-show=".pome">Pear</option>
</select>

<div class="my-info-1">
  <div class="citrus hide">Citrus is...</div>
  <div class="pome hide">A pome is...</div>
</div>

jQuery:

$(document).on('change', '.div-toggle', function() {
  var target = $(this).data('target');
  var show = $("option:selected", this).data('show');
  $(target).children().addClass('hide');
  $(show).removeClass('hide');
});
$(document).ready(function(){
    $('.div-toggle').trigger('change');
});

CSS:

.hide {
  display: none;
}

Here's a JSFiddle to see it in action.

I suggest you to use 2 queries:

1. db.collection.count() will return total number of items. This value is stored somewhere in Mongo and it is not calculated.

2. db.collection.find().skip(20).limit(10) here I assume you could use a sort by some field, so do not forget to add an index on this field. This query will be fast too.

I think that you shouldn't query all items and than perform skip and take, cause later when you have big data you will have problems with data transferring and processing.

Use substring method.

string s = "hello world";
s=s.Substring(10, s.Length-10);

I had a similar issue and running the command below fixed the error for me:

brew update && brew upgrade

Super rare - but still: On Windows, it might be that packed-refs has a branch with one letter case (i.e dev/mybranch), while refs folder has another case (i.e Dev/mybranch) when core.ignorecase is set to true.

The solution is to manually delete the relevant row from packed-refs. Didn't find a cleaner solution.

For non-printing characters, you can do the following:

• if you could identify the character, where cursor takes 2 arrow keys to move, just select that character.
• do Ctrl-F
• now you can count or replace or even mark all such characters

An improved version for recursive approach suggested by @schirrmacher to print key[value] for the entire object:

var jDepthLvl = 0;
function visit(object, objectAccessor=null) {
  jDepthLvl++;
  if (isIterable(object)) {
    if(objectAccessor === null) {
      console.log("%c ? ? printing object $OBJECT_OR_ARRAY$ -- START ? ?", "background:yellow");
    } else
      console.log("%c"+spacesDepth(jDepthLvl)+objectAccessor+"%c:","color:purple;font-weight:bold", "color:black");
    forEachIn(object, function (accessor, child) {
      visit(child, accessor);
    });
  } else {
    var value = object;
    console.log("%c"
      + spacesDepth(jDepthLvl)
      + objectAccessor + "[%c" + value + "%c] "
      ,"color:blue","color:red","color:blue");
  }
  if(objectAccessor === null) {
    console.log("%c ? ? printing object $OBJECT_OR_ARRAY$ -- END ? ?", "background:yellow");
  }
  jDepthLvl--;
}

function spacesDepth(jDepthLvl) {
  let jSpc="";
  for (let jIter=0; jIter<jDepthLvl-1; jIter++) {
    jSpc+="\u0020\u0020"
  }
  return jSpc;
}

function forEachIn(iterable, functionRef) {
  for (var accessor in iterable) {
    functionRef(accessor, iterable[accessor]);
  }
}

function isIterable(element) {
  return isArray(element) || isObject(element);
}

function isArray(element) {
  return element.constructor == Array;
}

function isObject(element) {
  return element.constructor == Object;
}


visit($OBJECT_OR_ARRAY$);

With the Date (and DateTime) classes you can do (end_date - start_date).to_i to get the number of days difference.

Even better then @Tanjim Rahman answer you can using Spring Data JPA use the method T getOne(ID id)

Customer customerToUpdate = customerRepository.getOne(id);
customerToUpdate.setName(customerDto.getName);
customerRepository.save(customerToUpdate);

Is's better because getOne(ID id) gets you only a reference (proxy) object and does not fetch it from the DB. On this reference you can set what you want and on save() it will do just an SQL UPDATE statement like you expect it. In comparsion when you call find() like in @Tanjim Rahmans answer spring data JPA will do an SQL SELECT to physically fetch the entity from the DB, which you dont need, when you are just updating.

Steps to debug coredump using GDB:

Some generic help:

gdb start GDB, with no debugging les

gdb program begin debugging program

gdb program core debug coredump core produced by program

gdb --help describe command line options

1. First of all, find the directory where the corefile is generated.

2. Then use ls -ltr command in the directory to find the latest generated corefile.

3. To load the corefile use

   gdb binary path of corefile
   

   This will load the corefile.

4. Then you can get the information using the bt command.

   For a detailed backtrace use bt full.

5. To print the variables, use print variable-name or p variable-name

6. To get any help on GDB, use the help option or use apropos search-topic

7. Use frame frame-number to go to the desired frame number.

8. Use up n and down n commands to select frame n frames up and select frame n frames down respectively.

9. To stop GDB, use quit or q.

I had a great deal of trouble with this. I just wanted to:

thisBill.IntervalCount = jPaidCountSpinner.getValue();

Where IntervalCount is a Long, and the JSpinner was set to return a Long. Eventually I had to write this function:

    public static final Long getLong(Object obj) throws IllegalArgumentException {
    Long rv;

    if((obj.getClass() == Integer.class) || (obj.getClass() == Long.class) || (obj.getClass() == Double.class)) {
        rv = Long.parseLong(obj.toString());
    }
    else if((obj.getClass() == int.class) || (obj.getClass() == long.class) || (obj.getClass() == double.class)) {
        rv = (Long) obj;
    }
    else if(obj.getClass() == String.class) {
        rv = Long.parseLong(obj.toString());
    }
    else {
        throw new IllegalArgumentException("getLong: type " + obj.getClass() + " = \"" + obj.toString() + "\" unaccounted for");
    }

    return rv;
}

which seems to do the trick. No amount of simple casting, none of the above solutions worked for me. Very frustrating.

While I agree with everyone else, if you are dead set on using frames anyway, you can just do index.html in XHTML and then do the contents of the frames in HTML5.

As offer_date is an number, and is of lower accuracy than your real dates, this may work...
- Convert your real date to a string of format YYYYMM
- Conver that value to an INT
- Compare the result you your offer_date

SELECT
  *
FROM
  offers
WHERE
    offer_date = (SELECT CAST(to_char(create_date, 'YYYYMM') AS INT) FROM customers where id = '12345678')
AND offer_rate > 0 

Also, by doing all the manipulation on the create_date you only do the processing on one value.

Additionally, had you manipulated the offer_date you would not be able to utilise any index on that field, and so force SCANs instead of SEEKs.

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

the reason to raise this exception is:

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

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

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

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

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

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

@Masci is correct, but in case you're using C (and the gcc compiler) take in account that this doesn't work:

gcc -ldl dlopentest.c

But this does:

gcc dlopentest.c -ldl

Took me a bit to figure out...

A 'drop down menu' is a web control / term. In iOS we don't have these. You might be better looking at UIPopoverController. Check out this tutorial for a bit of an insight to PopoverControllers

Why does nobody here consider using this simple code?

TCHAR szDir[MAX_PATH] = { 0 };

GetModuleFileName(NULL, szDir, MAX_PATH);
szDir[std::string(szDir).find_last_of("\\/")] = 0;

or even simpler

TCHAR szDir[MAX_PATH] = { 0 };
TCHAR* szEnd = nullptr;
GetModuleFileName(NULL, szDir, MAX_PATH);
szEnd = _tcsrchr(szDir, '\\');
*szEnd = 0;

Anyone using JavaScript (as opposed to JQuery), might like to try this solution, where 'models' is the ID of the select field containing the list :-

var DDlist = document.getElementById("models");
while(DDlist.length>0){DDlist.remove(0);}

ReducedForm is a type, so you cannot say

ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

You can only use the . operator on an instance:

ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

A good place to start is this: https://github.com/wasabeef/recyclerview-animators/blob/master/animators/src/main/java/jp/wasabeef/recyclerview/adapters/AnimationAdapter.java

You don't even need the full library, that class is enough. Then if you just implement your Adapter class giving an animator like this:

@Override
protected Animator[] getAnimators(View view) {
    return new Animator[]{
            ObjectAnimator.ofFloat(view, "translationY", view.getMeasuredHeight(), 0)
    };
}

@Override
public long getItemId(final int position) {
    return getWrappedAdapter().getItemId(position);
}

you'll see items appearing from the bottom as they scroll, also avoiding the problem with the fast scroll.

Plain Javascript regex does not handle Unicode letters.

Do not use [^\w\s], this will remove letters with accents (like àèéìòù), not to mention to Cyrillic or Chinese, letters coming from such languages will be completed removed.

You really don't want remove these letters together with all the special characters. You have two chances:

• Add in your regex all the special characters you don't want remove,
  for example: [^èéòàùì\w\s].
• Have a look at xregexp.com. XRegExp adds base support for Unicode matching via the \p{...} syntax.

var str = "????::: résd,$%& adùf"
var search = XRegExp('([^?<first>\\pL ]+)');
var res = XRegExp.replace(str, search, '',"all");

console.log(res); // returns "????::: resd,adf"
console.log(str.replace(/[^\w\s]/gi, '') ); // returns " rsd adf"
console.log(str.replace(/[^\wèéòàùì\s]/gi, '') ); // returns " résd adùf"

All major browsers now include native JSON encoding/decoding.

// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject); 

// To decode (This produces an object)
var obj = JSON.parse(json_str);

Note that only valid JSON data will be encoded. For example:

var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"

Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.

Some JSON resources:

• JSON on Mozilla Developer Network
• JSON on Wikipedia

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

Your script is being executed before the body element has even loaded.

There are a couple ways to workaround this.

• Wrap your code in a DOM Load callback:

  Wrap your logic in an event listener for DOMContentLoaded.

  In doing so, the callback will be executed when the body element has loaded.

  document.addEventListener('DOMContentLoaded', function () {
      // ...
      // Place code here.
      // ...
  });
  

  Depending on your needs, you can alternatively attach a load event listener to the window object:

  window.addEventListener('load', function () {
      // ...
      // Place code here.
      // ...
  });
  

  For the difference between between the DOMContentLoaded and load events, see this question.

• Move the position of your <script> element, and load JavaScript last:

  Right now, your <script> element is being loaded in the <head> element of your document. This means that it will be executed before the body has loaded. Google developers recommends moving the <script> tags to the end of your page so that all the HTML content is rendered before the JavaScript is processed.

  <!DOCTYPE html>
  <html>
  <head></head>
  <body>
    <p>Some paragraph</p>
    <!-- End of HTML content in the body tag -->
  
    <script>
      <!-- Place your script tags here. -->
    </script>
  </body>
  </html>
  

Try this:

def get_git_sha(git_dir='') {
    dir(git_dir) {
        return sh(returnStdout: true, script: 'git rev-parse HEAD').trim()
    }
}

node(BUILD_NODE) {
    ...
    repo_SHA = get_git_sha('src/FooBar.git')
    echo repo_SHA
    ...
}

Tested on:

• Jenkins ver. 2.19.1
• Pipeline 2.4

you need to do something like this,

SELECT * FROM buckets WHERE bucketname RLIKE 'Stylus.*2100';

or

SELECT * FROM buckets WHERE bucketname RLIKE '(Stylus)+.*(2100)+';

Including this in the read.csv command worked for me: strip.white = TRUE

(I found this solution here.)

###Quick solution:

With this kind of error, I usually start by raising the postBuffer size by:

git config --global http.postBuffer 524288000

(some comments below report having to double the value):

git config --global http.postBuffer 1048576000

(For npm publish, Martin Braun reports in the comments setting it to no more than 50 000 000 instead of the default 1 000 000)

###More information:

From the git config man page, http.postBuffer is about:

Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system.
For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

Even for the clone, that can have an effect, and in this instance, the OP Joe reports:

[clone] works fine now

Note: if something went wrong on the server side, and if the server uses Git 2.5+ (Q2 2015), the error message might be more explicit.
See "Git cloning: remote end hung up unexpectedly, tried changing postBuffer but still failing".

Kulai (in the comments) points out to this Atlassian Troubleshooting Git page, which adds:

Error code 56 indicates a curl receive the error of CURLE_RECV_ERROR which means there was some issue that prevented the data from being received during the cloning process.
Typically this is caused by a network setting, firewall, VPN client, or anti-virus that is terminating the connection before all data has been transferred.

It also mentions the following environment variable, order to help with the debugging process.

# Linux
export GIT_TRACE_PACKET=1
export GIT_TRACE=1
export GIT_CURL_VERBOSE=1

#Windows
set GIT_TRACE_PACKET=1
set GIT_TRACE=1
set GIT_CURL_VERBOSE=1

With Git 2.25.1 (Feb. 2020), you know more about this http.postBuffer "solution".

docs: mention when increasing http.postBuffer is valuable

^{Signed-off-by: brian m. carlson}

Users in a wide variety of situations find themselves with HTTP push problems.

Oftentimes these issues are due to antivirus software, filtering proxies, or other man-in-the-middle situations; other times, they are due to simple unreliability of the network.

However, a common solution to HTTP push problems found online is to increase http.postBuffer.

This works for none of the aforementioned situations and is only useful in a small, highly restricted number of cases: essentially, when the connection does not properly support HTTP/1.1.

Document when raising this value is appropriate and what it actually does, and discourage people from using it as a general solution for push problems, since it is not effective there.

So the documentation for git config http.postBuffer now includes:

http.postBuffer

Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system.
For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally.
Default is 1 MiB, which issufficient for most requests.

Note that raising this limit is only effective for disabling chunked transfer encoding and therefore should be used only where the remote server or a proxy only supports HTTP/1.0 or is noncompliant with the HTTP standard.
Raising this is not, in general, an effective solution for most push problems, but can increase memory consumption significantly since the entire buffer is allocated even for small pushes.

Previous answers got you list of torch.Size Here is how to get list of ints

listofints = [int(x) for x in tensor.shape]

On PostgreSQL you can use:

SELECT * FROM table_name WHERE (boolean_column IS NULL OR NOT boolean_column)

File.Create returns a FileStream. You need to close that when you have written to the file:

using (FileStream fs = File.Create(path, 1024)) 
        {
            Byte[] info = new UTF8Encoding(true).GetBytes("This is some text in the file.");
            // Add some information to the file.
            fs.Write(info, 0, info.Length);
        }

You can use using for automatically closing the file.

On Windows it's holding down Alt while box selecting. Once you have your selection then attempt your edit.

You can using the following code:

   if($(".parent a").attr('id')){

      //do something
   }


   $(".parent a").each(function(i,e){
       if($(e).attr('id')){
          //do something and check
          //if you want to break the each
          //return false;
       }
   });

The same question is you can find here: how to check if div has id or not?

In case any one wants it in Kotlin :

val dialogBuilder = AlertDialog.Builder(this)
// ...Irrelevant code for customizing the buttons and title
val dialogView = layoutInflater.inflate(R.layout.alert_label_editor, null)
dialogBuilder.setView(dialogView)

val editText =  dialogView.findViewById(R.id.label_field)
editText.setText("test label")
val alertDialog = dialogBuilder.create()
alertDialog.show()

Reposted @user370305's answer.

The simplest way to delete rows and columns from arrays is the numpy.delete method.

Suppose I have the following array x:

x = array([[1,2,3],
        [4,5,6],
        [7,8,9]])

To delete the first row, do this:

x = numpy.delete(x, (0), axis=0)

To delete the third column, do this:

x = numpy.delete(x,(2), axis=1)

So you could find the indices of the rows which have a 0 in them, put them in a list or a tuple and pass this as the second argument of the function.

SimpleDateFormat will not work if he is starting with LocalDate which is new in Java 8. From what I can see, you will have to use DateTimeFormatter, http://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html.

LocalDate localDate = LocalDate.now();//For reference
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd LLLL yyyy");
String formattedString = localDate.format(formatter);

That should print 05 May 1988. To get the period after the day and before the month, you might have to use "dd'.LLLL yyyy"

Not saying this is better, just another way:

$("#elem")[0].style.fontSize="20px";

SQL injection is the attempt to issue SQL commands to a database through a website interface, to gain other information. Namely, this information is stored database information such as usernames and passwords.

First rule of securing any script or page that attaches to a database instance is Do not trust user input.

Your example is attempting to end a misquoted string in an SQL statement. To understand this, you first need to understand SQL statements. In your example of adding a ' to a paramater, your 'injection' is hoping for the following type of statement:

SELECT username,password FROM users WHERE username='$username'

By appending a ' to that statement, you could then add additional SQL paramaters or queries.: ' OR username --

SELECT username,password FROM users WHERE username='' OR username -- '$username

That is an injection (one type of; Query Reshaping). The user input becomes an injected statement into the pre-written SQL statement.

Generally there are three types of SQL injection methods:

• Query Reshaping or redirection (above)
• Error message based (No such user/password)
• Blind Injections

Read up on SQL Injection, How to test for vulnerabilities, understanding and overcoming SQL injection, and this question (and related ones) on StackOverflow about avoiding injections.

Edit:

As far as TESTING your site for SQL injection, understand it gets A LOT more complex than just 'append a symbol'. If your site is critical, and you (or your company) can afford it, hire a professional pen tester. Failing that, this great exaxmple/proof can show you some common techniques one might use to perform an injection test. There is also SQLMap which can automate some tests for SQL Injection and database take over scenarios.

In case of HTML5 this will do the trick

window.onpopstate = function() {
   alert("clicked back button");
}; history.pushState({}, '');

I found my solution after hours of research here.

Stop MySQL

sudo service mysql stop

Make MySQL service directory.

sudo mkdir /var/run/mysqld

Give MySQL user permission to write to the service directory.

sudo chown mysql: /var/run/mysqld

Start MySQL manually, without permission checks or networking.

sudo mysqld_safe --skip-grant-tables --skip-networking &

Log in without a password.

 mysql -uroot mysql

update password

UPDATE mysql.user SET authentication_string=PASSWORD('YOURNEWPASSWORD'), plugin='mysql_native_password' WHERE User='root' AND Host='%';
EXIT;

Turn off MySQL.

sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown

Start the MySQL service normally.

sudo service mysql start

For the example above with "GetWelcomeMessage" you might need to specify "__stdcall" in the typedef field before the function name if getting error after calling imported function.

Well the problem simply-put is that the SUM(TIME) for a specific SSN on your query is a single value, so it's objecting to MAX as it makes no sense (The maximum of a single value is meaningless).

Not sure what SQL database server you're using but I suspect you want a query more like this (Written with a MSSQL background - may need some translating to the sql server you're using):

SELECT TOP 1 SSN, SUM(TIME)
FROM downloads
GROUP BY SSN
ORDER BY 2 DESC

This will give you the SSN with the highest total time and the total time for it.

Edit - If you have multiple with an equal time and want them all you would use:

SELECT
SSN, SUM(TIME)
FROM downloads
GROUP BY SSN
HAVING SUM(TIME)=(SELECT MAX(SUM(TIME)) FROM downloads GROUP BY SSN))

One of the most elegant solutions was here Get characters after last / in url

by DisgruntledGoat

$id = substr($url, strrpos($url, '/') + 1);

strrpos gets the position of the last occurrence of the slash; substr returns everything after that position.

So simple and concise. Thanks to the Open source developer, cketti for sharing this solution:

String mailto = "mailto:[email protected]" +
    "?cc=" + "[email protected]" +
    "&subject=" + Uri.encode(subject) +
    "&body=" + Uri.encode(bodyText);

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse(mailto));

try {
  startActivity(emailIntent);
} catch (ActivityNotFoundException e) {
  //TODO: Handle case where no email app is available
}

And this is the link to his/her gist.

You have to initialize the vector of vectors to the appropriate size before accessing any elements. You can do it like this:

// assumes using std::vector for brevity
vector<vector<int>> matrix(RR, vector<int>(CC));

This creates a vector of RR size CC vectors, filled with 0.

I found a solution for Chrome with CSS this following selector without bypassing the native verification form which could be very useful.

form input::-webkit-validation-bubble-message, 
form select::-webkit-validation-bubble-message,
form textarea::-webkit-validation-bubble-message {
    display:none;
} 

By this way, you can also customise your message...

I got the solution on this page : http://trac.webkit.org/wiki/Styling%20Form%20Controls

If your DataFrame has values with the same type, you can also set return_counts=True in numpy.unique().

index, counts = np.unique(df.values,return_counts=True)

np.bincount() could be faster if your values are integers.

All the solutions are correct, but I found it easier just write a function to implement this. like this:

template <class T1, class T2>
void ContainerInsert(T1 t1, T2 t2)
{
    t1->insert(t1->end(), t2->begin(), t2->end());
}

That way you can avoid the temporary placement like this:

ContainerInsert(vec, GetSomeVector());

Using pyquaternion is extremely simple; to install it (while still in python), run in your console:

import pip;
pip.main(['install','pyquaternion'])

Once installed:

  from pyquaternion import Quaternion
  v = [3,5,0]
  axis = [4,4,1]
  theta = 1.2 #radian
  rotated_v = Quaternion(axis=axis,angle=theta).rotate(v)

Hi I have the most easiest code try this

    public class ImageFromUrlExample extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);  
            ImageView imgView =(ImageView)findViewById(R.id.ImageView01);
            Drawable drawable = LoadImageFromWebOperations("http://www.androidpeople.com/wp-content/uploads/2010/03/android.png");
            imgView.setImageDrawable(drawable);

    }

    private Drawable LoadImageFromWebOperations(String url)
    {
          try{
        InputStream is = (InputStream) new URL(url).getContent();
        Drawable d = Drawable.createFromStream(is, "src name");
        return d;
      }catch (Exception e) {
        System.out.println("Exc="+e);
        return null;
      }
    }
   }

main.xml

  <LinearLayout 
    android:id="@+id/LinearLayout01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">
   <ImageView 
       android:id="@+id/ImageView01"
       android:layout_height="wrap_content" 
       android:layout_width="wrap_content"/>

try this

You need to type cast using as operator like this.

private void MyMethod(object myObject)  
{  
if(myObject is IEnumerable)  
{
    List<object> collection = myObject as(List<object>); 
    ... do something   
}  
else  
{  
    ... do something  
}  
}      

You try the following ways to run the multiple python scripts:

  import os
  print "Starting script1"
  os.system("python script1.py arg1 arg2 arg3")
  print "script1 ended"
  print "Starting script2"
  os.system("python script2.py arg1 arg2 arg3")
  print "script2 ended"

Note: The execution of multiple scripts depends purely underlined operating system, and it won't be concurrent, I was new comer in Python when I answered it.

Update: I found a package: https://pypi.org/project/schedule/ Above package can be used to run multiple scripts and function, please check this and maybe on weekend will provide some example too.

i.e:

 import schedule
 import time
 import script1, script2

 def job():
     print("I'm working...")

 schedule.every(10).minutes.do(job)
 schedule.every().hour.do(job)
 schedule.every().day.at("10:30").do(job)
 schedule.every(5).to(10).days.do(job)
 schedule.every().monday.do(job)
 schedule.every().wednesday.at("13:15").do(job)

 while True:
     schedule.run_pending()
     time.sleep(1)

Split is slow, but not as slow as Scanner. StringTokenizer is faster than split. However, I found that I could obtain double the speed, by trading some flexibility, to get a speed-boost, which I did at JFastParser https://github.com/hughperkins/jfastparser

Testing on a string containing one million doubles:

Scanner: 10642 ms
Split: 715 ms
StringTokenizer: 544ms
JFastParser: 290ms

Loading local JSON file

Use something like this

$.getJSON("../../data/file.json", function(json) {
    console.log(json); // this will show the info in firebug console 
    alert(json);
});

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

As other answers pointed out, it is most likely generated by some tool.

But if I were the original author of the file, my answer would be: Consistency.

If I am not allowed to put double quotes in my attributes, why put them in the element's content ? Why do these specs always have these exceptional cases .. If I had to write the HTML spec, I would say All double quotes need to be encoded. Done.

Today it is like In attribute values we need to encode double quotes, except when the attribute value itself is defined by single quotes. In the content of elements, double quotes can be, but are not required to be, encoded. (And I am surely forgetting some cases here).

Double quotes are a keyword of the spec, encode them. Lesser/greater than are a keyword of the spec, encode them. etc..

My understanding is very simple below.

Factory: You simply create an object inside of the factory and return it.

Service:

You just have a standard function that uses this keyword to define a function.

Provider:

There is a $get object that you define and it can be used to get the object that returns data.

The stopPropagation() method stops the bubbling of an event to parent elements, preventing any parent handlers from being notified of the event.

You can use the method event.isPropagationStopped() to know whether this method was ever called (on that event object).

Syntax:

Here is the simple syntax to use this method:

event.stopPropagation() 

Example:

$("div").click(function(event) {
    alert("This is : " + $(this).prop('id'));

    // Comment the following to see the difference
    event.stopPropagation();
});?

Use etree.indent and etree.tostring

import lxml.etree as etree

root = etree.fromstring('<html><head></head><body><h1>Welcome</h1></body></html>')
etree.indent(root, space="  ")
xml_string = etree.tostring(root, pretty_print=True).decode()
print(xml_string)

output

<html>
  <head/>
  <body>
    <h1>Welcome</h1>
  </body>
</html>

Removing namespaces and prefixes

import lxml.etree as etree


def dump_xml(element):
    for item in element.getiterator():
        item.tag = etree.QName(item).localname

    etree.cleanup_namespaces(element)
    etree.indent(element, space="  ")
    result = etree.tostring(element, pretty_print=True).decode()
    return result


root = etree.fromstring('<cs:document xmlns:cs="http://blabla.com"><name>hello world</name></cs:document>')
xml_string = dump_xml(root)
print(xml_string)

output

<document>
  <name>hello world</name>
</document>

Vanilla Javascript solution

HTML

<div id="mydiv" data-myval="10"></div>

JavaScript:

• Using DOM's getAttribute() property

   var brand = mydiv.getAttribute("data-myval")//returns "10"
   mydiv.setAttribute("data-myval", "20")      //changes "data-myval" to "20"
   mydiv.removeAttribute("data-myval")         //removes "data-myval" attribute entirely
  

• Using JavaScript's dataset property

  var myval = mydiv.dataset.myval     //returns "10"
  mydiv.dataset.myval = '20'          //changes "data-myval" to "20"
  mydiv.dataset.myval = null          //removes "data-myval" attribute
  

The problem with information_schema is that it can be terribly slow. It is faster to use the SHOW commands.

After you select the database you first send the query SHOW TABLES. And then you do SHOW COLUMNS for each of the tables.

In PHP that would look something like

    $res = mysqli_query("SHOW TABLES");
    while($row = mysqli_fetch_array($res))
    {   $rs2 = mysqli_query("SHOW COLUMNS FROM ".$row[0]);
        while($rw2 = mysqli_fetch_array($rs2))
        {   if($rw2[0] == $target)
               ....
        }
    }

Oracle 11g Release 2 supports the LISTAGG function. Documentation here.

Warning

Be careful implementing this function if there is possibility of the resulting string going over 4000 characters. It will throw an exception. If that's the case then you need to either handle the exception or roll your own function that prevents the joined string from going over 4000 characters.

The solution of @user8178061 worked well but I did it with some modifications for my version wich is python3.7 with Ubuntu

I replaced the apt_pkg.cpython-3m-i386-linux-gnu.so with apt_pkg.cpython-36m-x86_64-linux-gnu.so

Here the two commands to execute:

cd /usr/lib/python3/dist-packages

sudo cp apt_pkg.cpython-36m-x86_64-linux-gnu.so apt_pkg.so

As many other people have pointed out, just extracting the .jar from the .aar file doesn't quite cut it as resources may be missing.

Here are the steps that worked for me (context of Android, your mileage may vary if you have other purposes):

1. Rename the .aar file to .zip and extract.
2. The extracted folder is an ADT project that you can import in Eclipse with some minor modifications (see below)!
3. In the extracted folder rename the contained file classes.jar to whatever you like (in this example myProjectLib.jar) and move it to the lib folder within the extracted folder.
4. Now in order for Eclipse to accept it you need to put two files into the extracted folder root:
   • .project
   • .classpath
5. To do that, create a new Android dummy project in Eclipse and copy over the files, or copy over from an existing Android project.
6. Open the .project file and look for the XML name tag and replace the contents of it with myProjectLib (or whatever you called your jar file above) and save.
7. Now in Eclipse you can File -> New -> Project -> Android Project from existing source.. and point to the extracted folder content.
8. After import right click on the newly created project, select Properties -> Android, and check Is Library.
9. In your main project that you want to use the library for, also go to Properties -> Android and add the newly added myProjectLib to the list of dependencies.

          </ul>
       </li>
    </ul>
    )
    }
    })
    return (
    <div>
       {newMenu}
    </div>
    );
    }
    }

I've used this creating an IFrame through Javascript and it worked for me:

// IFrame points to the IFrame element, obviously
IFrame.src = 'about: blank';
IFrame.style.backgroundColor = "transparent";
IFrame.frameBorder = "0";
IFrame.allowTransparency="true";

Not sure if it makes any difference, but I set those properties before adding the IFrame to the DOM. After adding it to the DOM, I set its src to the real URL.

(Using system.IO)

You can simply use \n for newline and \t in front of the string to indent it.

For example in c#:

public string theXML() {
    string xml = "";
    xml += "<Scene>\n";
    xml += "\t<Character>\n";


    xml += "\t</Character>\n";
    xml += "</Scene>\n";
    return xml;
}

This will result in the output: http://prntscr.com/96dfqc

You don't add or link directly against a DLL, you link against the LIB produced by the DLL.

A LIB provides symbols and other necessary data to either include a library in your code (static linking) or refer to the DLL (dynamic linking).

To link against a LIB, you need to add it to the project Properties -> Linker -> Input -> Additional Dependencies list. All LIB files here will be used in linking. You can also use a pragma like so:

#pragma comment(lib, "dll.lib")

With static linking, the code is included in your executable and there are no runtime dependencies. Dynamic linking requires a DLL with matching name and symbols be available within the search path (which is not just the path or system directory).

It's a GNU extension. In a nutshell it's a convenient way to declare an object having the same type as another. For example:

int x;         /* Plain old int variable. */
typeof(x) y;   /* Same type as x. Plain old int variable. */

It works entirely at compile-time and it's primarily used in macros. One famous example of macro relying on typeof is container_of.

Just a simplified answer to the best answer:

const rootReducer = combineReducers({
    auth: authReducer,
    ...formReducers,
    routing
});


export default (state, action) =>
  rootReducer(action.type === 'USER_LOGOUT' ? undefined : state, action);

Just put your globals in the file you are importing.

The simplest way to get the visitor’s/client’s IP address is using the $_SERVER['REMOTE_ADDR'] or $_SERVER['REMOTE_HOST'] variables.

However, sometimes this does not return the correct IP address of the visitor, so we can use some other server variables to get the IP address.

The below both functions are equivalent with the difference only in how and from where the values are retrieved.

getenv() is used to get the value of an environment variable in PHP.

// Function to get the client IP address
function get_client_ip() {
    $ipaddress = '';
    if (getenv('HTTP_CLIENT_IP'))
        $ipaddress = getenv('HTTP_CLIENT_IP');
    else if(getenv('HTTP_X_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_X_FORWARDED_FOR');
    else if(getenv('HTTP_X_FORWARDED'))
        $ipaddress = getenv('HTTP_X_FORWARDED');
    else if(getenv('HTTP_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_FORWARDED_FOR');
    else if(getenv('HTTP_FORWARDED'))
       $ipaddress = getenv('HTTP_FORWARDED');
    else if(getenv('REMOTE_ADDR'))
        $ipaddress = getenv('REMOTE_ADDR');
    else
        $ipaddress = 'UNKNOWN';
    return $ipaddress;
}

$_SERVER is an array that contains server variables created by the web server.

// Function to get the client IP address
function get_client_ip() {
    $ipaddress = '';
    if (isset($_SERVER['HTTP_CLIENT_IP']))
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if(isset($_SERVER['HTTP_X_FORWARDED']))
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if(isset($_SERVER['HTTP_FORWARDED']))
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if(isset($_SERVER['REMOTE_ADDR']))
        $ipaddress = $_SERVER['REMOTE_ADDR'];
    else
        $ipaddress = 'UNKNOWN';
    return $ipaddress;
}

You can do this with a table value parameters.

Have a look at the following article:

http://www.codeproject.com/Articles/39161/C-and-Table-Value-Parameters

You can also run arbitrary commands using the Groovy Post Build - and that will give you a lot of control over when they run and so forth. We use that to run a 'finger of blame' shell script in the case of failed or unstable builds.

if (manager.build.result.isWorseThan(hudson.model.Result.SUCCESS)) {
  item = hudson.model.Hudson.instance.getItem("PROJECTNAMEHERE")
  lastStableBuild = item.getLastStableBuild()
  lastStableDate = lastStableBuild.getTime()
  formattedLastStableDate = lastStableDate.format("MM/dd/yyyy h:mm:ss a")
  now = new Date()
  formattedNow = now.format("MM/dd/yyyy h:mm:ss a")
  command = ['/appframe/jenkins/appframework/fob.ksh', "${formattedLastStableDate}", "${formattedNow}"]
  manager.listener.logger.println "FOB Command: ${command}"
  manager.listener.logger.println command.execute().text
}

(Our command takes the last stable build date and the current time as parameters so it can go investigate who might have broken the build, but you could run whatever commands you like in a similar fashion)

Maybe try the Intl polyfill for IE8 or the olyfill service ?

or

https://github.com/andyearnshaw/Intl.js/

Here's one suggestion:

public interface Service<T,U> {
    T executeService(U... args);
}

public class MyService implements Service<String, Integer> {
    @Override
    public String executeService(Integer... args) {
        // do stuff
        return null;
    }
}

Because of type erasure any class will only be able to implement one of these. This eliminates the redundant method at least.

It's not an unreasonable interface that you're proposing but I'm not 100% sure of what value it adds either. You might just want to use the standard Callable interface. It doesn't support arguments but that part of the interface has the least value (imho).

There is no append method in std::vector, but if you want to make a vector containing A_NUMBER vectors of int, each of those containing other_number zeros, then you can do this:

std::vector<std::vector<int>> fog(A_NUMBER, std::vector<int>(OTHER_NUMBER));

try this regex (allowing Alphabets, Dots, Spaces):

"^[A-Za-z\s]{1,}[\.]{0,1}[A-Za-z\s]{0,}$" //regular
"^\pL+[\pL\pZ\pP]{0,}$" //unicode

This will also ensure DOT never comes at the start of the name.

The form post values are stored under the name of the form in the request. For example, if you've overridden the getName() method of ContactType() to return "contact", you would do this:

$postData = $request->request->get('contact');
$name_value = $postData['name'];

If you're still having trouble, try doing a var_dump() on $request->request->all() to see all the post values.

$('#demoTable td').contents().each(function() {
    if (this.nodeType === 3) {
        this.textContent
        ? this.textContent = 'The text has been '
        : this.innerText  = 'The text has been '
    } else {
        this.innerHTML = 'changed';
        return false;
    }
})

http://jsfiddle.net/YSAjU/

There are different ways but simplest would be to use the space-between see the example at the end

#container {    
    border: solid 1px #000;
    display: flex;    
    flex-direction: row;
    justify-content: space-between;
    padding: 10px;
    height: 50px;
}

.item {
    width: 20%;
    border: solid 1px #000;
    text-align: center;
}

see the example

You can change your text or Content or Attribute depend on Screen size: HTML:

<p class="change">Frequently Asked Questions (FAQ)</p>
<p class="change">Frequently Asked Questions </p>

Javascript:

<script>
const changeText = document.querySelector('.change');
function resize() {
  if((window.innerWidth<500)&&(changeText.textContent="Frequently Asked Questions (FAQ)")){
    changeText.textContent="FAQ";
  } else {
    changeText.textContent="Frequently Asked Questions (FAQ)";
  }
}
window.onresize = resize;
</script>

Group your report data based on the category that you want your sheets to be based on. Specify that you want that grouping to start a new page for every new category. Each page becomes a new worksheet in the Excel workbook.

Note: I use SQL Server 2003 and Excel 2003.

Here's how you can change the android sdk path in Android studio:

1. Open your required android project in Android studio
2. Click on the main project folder and press F4
3. Now click on "SDKs" under Platform Settings (Left hand side of the dialog box)
4. You should now see a plus sign on the top, click it and choose "Android SDK"
5. Now you would be asked to choose the required SDK folder
6. Select the required build target(if necessary) and click "ok"
7. Now you should see the new entry in the list of SDKs
8. Click "Modules" under Project Settings
9. Select your project folder and in the Dropdown for "Module SDK", select the new SDK entry and click "apply"
10. Now click "OK" and your done.

Note: If changes do not take effect, restarting android studio should fix the problem.

You can also convert from one file type to another using the following command :

iconv -f original_charset -t new_charset originalfile > newfile

e.g.

iconv -f utf-16le -t utf-8 file1.txt > file2.txt

To resolve this for my situation:

I had to specify a more specific sub-package to install.

Wrong:

go get github.com/garyburd/redigo

Correct:

go get github.com/garyburd/redigo/redis

I had a similar problem when posting to the WebAPI endpoint. By turning the CustomErrors=Off, i was able to see the actual error which is one of the dlls was missing.

"%~1" will work most of the time. However there are a few things you need to note for this:

1. It's not supported in Windows NT 4.0. You need Windows 2000 or later. (If you are coding a script compatible with old OS, beware.)
2. It does not make parameters secure and sanitized. My observation is that there is no way to properly sanitize the command line arguments in CMD scripts.

To demonstrate second point, let me give an example:

REM example.cmd
ECHO %~1

Run with example.cmd dummy^&DIR . The ampersand is escaped here ( ^& ) to prevent shell from interpreting as a command delimiter, so that it becomes part of the argument passed to the script. The DIR is interpreted as a command inside the sub-shell running the script, where it shouldn't.

Quoting it might work some time, but still insecure:

REM example2.cmd
SETLOCAL EnableExtensions EnableDelayedExpansion
SET "arg1=%~1"
ECHO "%~1"
ECHO !arg1:"=!

example2.cmd foo^"^&DIR^&^"bar will break it. DIR command will be run two times, one right after SET and the other right after the first ECHO. You see that the "%~1" you think is quoted well gets unquoted by the argument itself.

So, no way to make parsing arguments secure.

(EDIT: EnableDelayedExpansion doesn't work in Windows NT 4 either. Thanks to the info here: http://www.robvanderwoude.com/local.php)

You can try that command

git clean -df

Try this code

private void clearAppData() {
    try {
        if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager)getSystemService(ACTIVITY_SERVICE)).clearApplicationUserData();
        } else {
            Runtime.getRuntime().exec("pm clear " + getApplicationContext().getPackageName());
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

You can push with using different account. For example, if your account is A which is stored in .gitconfig and you want to use account B which is the owner of the repo you want to push.

Account B: B_user_name, B_password
Example of SSH link: https://github.com/B_user_name/project.git

The push with B account is:

$ git push https://'B_user_name':'B_password'@github.com/B_user_name/project.git

To see the account in .gitconfig

1. $git config --global --list
2. $git config --global -e (to change account also)

On my system: CentOS 5

I can use \s outside of collections but have to use [:space:] inside of collections. In fact I can use [:space:] only inside collections. So to match a single space using this I have to use [[:space:]] Which is really strange.

echo a b cX | sed -r "s/(a\sb[[:space:]]c[^[:space:]])/Result: \1/"

Result: a b cX

• first space I match with \s
• second space I match alternatively with [[:space:]]
• the X I match with "all but no space" [^[:space:]]

These two will not work:

a[:space:]b  instead use a\sb or a[[:space:]]b

a[^\s]b      instead use a[^[:space:]]b

Under VS2013 you can install the new compilers into the project as a nuget package. That way you don't need VS2015 or an updated build server.

https://www.nuget.org/packages/Microsoft.Net.Compilers/

Install-Package Microsoft.Net.Compilers

The package allows you to use/build C# 6.0 code/syntax. Because VS2013 doesn't natively recognize the new C# 6.0 syntax, it will show errors in the code editor window although it will build fine.

Using Resharper, you'll get squiggly lines on C# 6 features, but the bulb gives you the option to 'Enable C# 6.0 support for this project' (setting saved to .DotSettings).

As mentioned by @stimpy77: for support in MVC Razor views you'll need an extra package (for those that don't read the comments)

Install-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform

If you want full C# 6.0 support, you'll need to install VS2015.

The problem was actually solved by providing crossOrigin: null to OpenLayers OSM source:

var newLayer = new ol.layer.Tile({
source: new ol.source.OSM({
    url: 'E:/Maperitive/Tiles/vychod/{z}/{x}/{y}.png',
    crossOrigin: null
    })
});

Using exc_info options may be better, to allow you to choose the error level (if you use exception, it will always be at the error level):

try:
    # do something here
except Exception as e:
    logging.critical(e, exc_info=True)  # log exception info at CRITICAL log level

git reset --hard 4a155e5 Will move the HEAD back to where you want to be. There may be other references ahead of that time that you would need to remove if you don't want anything to point to the history you just deleted.

Webkit is an HTML rendering engine used by Chrome and Safari.

It supports a number of custom CSS properties that are prefixed by -webkit-.

Use pkill -f, which matches the pattern for any part of the command line

pkill -f my_pattern

get_template_directory_uri();

This function will help you retrieve theme directory URI, and can be used with your images, your example below:

<img src="<?php echo get_template_directory_uri(); ?>/images/mindset.jpg" />

To remove duplicates from a single column

 Sub removeDuplicate()
 'removeDuplicate Macro
 Columns("A:A").Select
 ActiveSheet.Range("$A$1:$A$117").RemoveDuplicates Columns:=Array(1), _ 
 Header:=xlNo 
 Range("A1").Select
 End Sub

if you have header then use Header:=xlYes

Increase your range as per your requirement.
you can make it to 1000 like this :

ActiveSheet.Range("$A$1:$A$1000")

So that you don't mess up other permissions already on the file, use the flag +, such as via

sudo chmod -R o+rw /var/www

DbContext has a constructor overload that accepts the name of a connection string or a connection string itself. Implement your own version and pass it to the base constructor:

public class MyDbContext : DbContext
{
    public MyDbContext( string nameOrConnectionString ) 
        : base( nameOrConnectionString )
    {
    }
}

Then simply pass the name of a configured connection string or a connection string itself when you instantiate your DbContext

var context = new MyDbContext( "..." );

Easiest way is defining track tint, and setting tint mode to src_over to remove 30% transparency.

android:trackTint="@drawable/toggle_style"
android:trackTintMode="src_over"

toggle_style.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/informationDefault"
        android:state_checked="true"
        />
    <item android:color="@color/textDisabled" android:state_checked="false"/>
</selector>

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()

To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N

Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start 

And the GDB command to print N elements of an array starting at pointer P is:

print P@N

Or, in a short form (for a standard .gdbinit):

p P@N

Use the method "toArray()"

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
Object[] mStringArray = mStringList.toArray();

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

or you can do it like this: (mentioned in other answers)

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
String[] mStringArray = new String[mStringList.size()];
mStringArray = mStringList.toArray(mStringArray);

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File("c:\\NewFolder\\screenshot1.jpg"));

no need to use user and password as part of the URL

you can try this

byte[] encodedBytes = Base64.encodeBase64("user:passwd".getBytes());

String USER_PASS = new String(encodedBytes);

HttpUriRequest request = RequestBuilder.get(url).addHeader("Authorization", USER_PASS).build();

Another alternative would be to show a Toast/Snackbar on the first back press asking to press back again to Exit, which is a lot less intrusive than showing an AlertDialog to confirm if user wants to exit the app.

You can use the DoubleBackPress Android Library to achieve this with a few lines of code. Example GIF showing similar behaviour.

To begin with, add the dependency to your application :

dependencies {
    implementation 'com.github.kaushikthedeveloper:double-back-press:0.0.1'
}

Next, in your Activity, implement the required behaviour.

// set the Toast to be shown on FirstBackPress (ToastDisplay - builtin template)
// can be replaced by custom action (new FirstBackPressAction{...})
FirstBackPressAction firstBackPressAction = new ToastDisplay().standard(this);

// set the Action on DoubleBackPress
DoubleBackPressAction doubleBackPressAction = new DoubleBackPressAction() {
    @Override
    public void actionCall() {
        // TODO : Exit the application
        finish();
        System.exit(0);
    }
};

// setup DoubleBackPress behaviour : close the current Activity
DoubleBackPress doubleBackPress = new DoubleBackPress()
        .withDoublePressDuration(3000)     // msec - wait for second back press
        .withFirstBackPressAction(firstBackPressAction)
        .withDoubleBackPressAction(doubleBackPressAction);

Finally, set this as the behaviour on back press.

@Override
public void onBackPressed() {
    doubleBackPress.onBackPressed();
}

Haha, Lovely - let me also include my version of stackPusher's code :). We are using this functionality in C#. Works fine for all Excel ranges.:

public static String ConvertToLiteral(int number)
{
        int firstLetter = (((number - 27) / (26 * 26))) % 26;
        int middleLetter = ((((number - 1) / 26)) % 26);

        int lastLetter = (number % 26);
        firstLetter = firstLetter == 0 ? 26 : firstLetter;
        middleLetter = middleLetter == 0 ? 26 : middleLetter;
        lastLetter = lastLetter == 0 ? 26 : lastLetter;
        String returnedString = "";
        returnedString = number > 27 * 26 ? (Convert.ToChar(firstLetter + 64).ToString()) : returnedString;
        returnedString += number > 26 ? (Convert.ToChar(middleLetter + 64).ToString()) : returnedString;
        returnedString += lastLetter >= 0 ? (Convert.ToChar(lastLetter + 64).ToString()) : returnedString;
        return returnedString;
}

Assuming I understand what you mean:

1. If your UserControl is in a library you can add this to you Toolbox using

   Toolbox -> right click -> Choose Items -> Browse

   Select your assembly with the UserControl.

2. If the UserControl is part of your project you only need to build the entire solution. After that, your UserControl should appear in the toolbox.

In general, it is not possible to add a Control from Solution Explorer, only from the Toolbox.

For me I modified both the AppTheme and a value colors.xml Both the colorControlNormal and the colorAccent helped me change the EditText border color. As well as the cursor, and the "|" when inside an EditText.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorControlNormal">@color/yellow</item>
    <item name="colorAccent">@color/yellow</item>
</style>

Here is the colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="yellow">#B7EC2A</color>
</resources>

I took out the android:textCursorDrawable attribute to @null that I placed inside the editText style. When I tried using this, the colors would not change.

You can debug this in many different ways. Here's my approach.

localsettings.py:

DEBUG = False
DEBUG404 = True

urls.py:

from django.conf import settings
import os

if settings.DEBUG404:
    urlpatterns += patterns('',
        (r'^static/(?P<path>.*)$', 'django.views.static.serve',
         {'document_root': os.path.join(os.path.dirname(__file__), 'static')} ),
    )

Be sure to read the docs ;)

Run the following commands:

$ git checkout mobiledevice
$ git pull origin master 

This would merge all the latest commits to your branch. If the merge results in some conflicts, you'll need to fix them.

I don't know if this is the best practice but works for me.

This should do it:

<%= f.select :project_id, @project_select, :selected => params[:pid] %>

You're looking for things like the haversine formula. See here as well.

There's other ones but this is the most commonly cited.

If you're looking for something even more robust, you might want to look at your databases GIS capabilities. They're capable of some cool things like telling you whether a point (City) appears within a given polygon (Region, Country, Continent).

you can simply add a method (setAttributes, with "s" at the end) to "Element" prototype like:

Element.prototype.setAttributes = function(obj){
  for(var prop in obj) {
    this.setAttribute(prop, obj[prop])
  }
}

you can define it in one line:

Element.prototype.setAttributes = function(obj){ for(var prop in obj) this.setAttribute(prop, obj[prop]) }

and you can call it normally as you call the other methods. The attributes are given as an object:

elem.setAttributes({"src": "http://example.com/something.jpeg", "height": "100%", "width": "100%"})

you can add an if statement to throw an error if the given argument is not an object.

You should set the timezone to the one of the timezones you want.

// set default timezone
date_default_timezone_set('America/Chicago'); // CDT

$info = getdate();
$date = $info['mday'];
$month = $info['mon'];
$year = $info['year'];
$hour = $info['hours'];
$min = $info['minutes'];
$sec = $info['seconds'];

$current_date = "$date/$month/$year == $hour:$min:$sec";

Or a much shorter version:

// set default timezone
date_default_timezone_set('America/Chicago'); // CDT

$current_date = date('d/m/Y == H:i:s');

String fileName="foo.bar";
int dotIndex=fileName.lastIndexOf('.');
if(dotIndex>=0) { // to prevent exception if there is no dot
  fileName=fileName.substring(0,dotIndex);
}

Is this a trick question? :p

I can't think of a faster way atm.

In Jupyter Lab 2.1.5, it is View -> Show Line Numbers.

You are missing a :selected on the selector for show() - see the jQuery documentation for an example of how to use this.

In your case it will probably look something like this:

$('#'+$('#colorselector option:selected').val()).show();

You might also consider using crypt()* to generate a [nearly-guaranteed] unique ID inside your contraints.

Try this in your constructor

MainActivity maniActivity = (MainActivity)context;
EditText firstName = (EditText) maniActivity.findViewById(R.id.display_name);

Answering the question: to remove the last character, just use:string = string[:-1].

If you want to remove the last '\' if there is one (or if there is more than one):

while string[-1]=='\\':
    string = string[:-1]

If it's a path, then use the os.path functions:

dir = "dir1\\dir2\\file.jpg\\"   #I'm using windows by the way
os.path.dirname(dir)

although I would 'add' a slash in the end to prevent missing the filename in case there's no slash at the end of the original string:

dir = "dir1\\dir2\\file.jpg"
os.path.dirname(dir + "\\")

When using abspath, (if the path isn't absolute I guess,) will add the current working directory to the path.

os.path.abspath(dir)

I just used getLocaleString() function for my application. It should adapt the timeformat common to the locale, so no +0200 etc. Ofcourse, there will be less possibility for controlling the width of your string then.

var str = (new Date(1400167800)).toLocaleString();

There is an operator in C called the comma operator. It executes each expression in order and returns the value of the last statement. It's also a sequence point, meaning each expression is guaranteed to execute in completely and in order before the next expression in the series executes, similar to && or ||.

myString.Length; //will get you your result
//alternatively, if you only want the count of letters:
myString.Count(char.IsLetter);
//however, if you want to display the words as ***_***** (where _ is a space)
//you can also use this:
//small note: that will fail with a repeated word, so check your repeats!
myString.Split(' ').ToDictionary(n => n, n => n.Length);
//or if you just want the strings and get the counts later:
myString.Split(' ');
//will not fail with repeats
//and neither will this, which will also get you the counts:
myString.Split(' ').Select(n => new KeyValuePair<string, int>(n, n.Length));

Your system is missing the mysqlnd driver!

If you are able to install new packages on your (Debian/Ubuntu-based) server, install the driver:

sudo apt-get install php5-mysqlnd

and then restart your web server:

sudo /etc/init.d/apache2 restart

Easiest way to reverse a string:

    backwards = input("Enter string to reverse: ")
    print(backwards[::-1])

int intNumber = (int)uintNumber;

Depending on what kind of values you are expecting, you may want to check how big uintNumber is before doing the conversion. An int has a max value of about .5 of a uint.

An authority is a portion of a URI. Your error suggests that it was not expecting one. The authority section is shown below, it is what is known as the website part of the url.

From RFC3986 on URIs:

The following is an example URI and its component parts:

     foo://example.com:8042/over/there?name=ferret#nose
     \_/   \______________/\_________/ \_________/ \__/
      |           |            |            |        |
   scheme     authority       path        query   fragment
      |   _____________________|__
     / \ /                        \
     urn:example:animal:ferret:nose

So there are two formats, one with an authority and one not. Regarding slashes:

"When authority is not present, the path cannot begin with two slash
characters ("//")."

Source: https://tools.ietf.org/rfc/rfc3986.txt (search for text 'authority is not present, the path cannot begin with two slash')

What I usually do for putting alert box (e.g. Note or Warning) in markdown texts (not only when using pandoc but also every where that markdown is supported) is surrounding the content with two horizontal lines:

---
**NOTE**

It works with almost all markdown flavours (the below blank line matters).

---

which would be something like this:

NOTE

It works with all markdown flavours (the below blank line matters).

The good thing is that you don't need to worry about which markdown flavour is supported or which extension is installed or enabled.

EDIT: As @filups21 has mentioned in the comments, it seems that a horizontal line is represented by *** in RMarkdown. So, the solution mentioned before does not work with all markdown flavours as it was originally claimed.

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

letter = ["a", "b", "c", "d"]
letter.extend(["e", "f", "g", "h"])
letter.extend(("e", "f", "g", "h"))
print(letter)
... 
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'e', 'f', 'g', 'h']
    

you can save the xlsx file as a tab-delimited text file and do

BULK INSERT TableName
        FROM 'C:\SomeDirectory\my table.txt'
            WITH
    (
                FIELDTERMINATOR = '\t',
                ROWTERMINATOR = '\n'
    )
GO

We can simply add ?wmode=transparent to the end of YouTube URL. This will tell YouTube to include the video with the wmode set. So you new embed code will look like this:-

Find the PID of a process that uses a port on Windows (e.g. port: "9999")

netstat -aon | find "9999"

-a Displays all connections and listening ports.

-o Displays the owning process ID associated with each connection.

-n Displays addresses and port numbers in numerical form.

Output:

TCP    0.0.0.0:9999       0.0.0.0:0       LISTENING       15776

Then kill the process by PID

taskkill /F /PID 15776

/F - Specifies to forcefully terminate the process(es).

Note: You may need an extra permission (run from administrator) to kill some certain processes

Here is a version inspired by this thread that more closely mimics distutils.file_util.copy_file.

updateonly is a bool if True, will only copy files with modified dates newer than existing files in dst unless listed in forceupdate which will copy regardless.

ignore and forceupdate expect lists of filenames or folder/filenames relative to src and accept Unix-style wildcards similar to glob or fnmatch.

The function returns a list of files copied (or would be copied if dryrun if True).

Assuming that your quoted text is the exact text, one of these columns can't do the mathematical calculations that you want. Double click on the error and it will highlight the line that's causing the problems (if it's different than what's posted, it may not be up there); I tested your code with the variables and there was no problem, meaning that one of these columns (which we don't know more specific information about) is creating this error.

One of your expressions needs to be casted/converted to an int in order for this to go through, which is the meaning of Arithmetic overflow error converting expression to data type int.

You may start with Titanium for desktop dev. Also you may have a look at Chromium Embedded Framework. It's basically a web browser control based on chromium.

It's written in C++ so you can do all the low level OS stuff you want(Growl, tray icons, local file access, com ports, etc) in your container app, and then all the application logic and gui in html/javascript. It allows you to intercept any http request to either serve local resources or perform some custom action. For example, a request to http://localapp.com/SetTrayIconState?state=active could be intercepted by the container and then call the C++ function to update the tray icon.

It also allows you to create functions that can be called directly from JavaScript.

It's very difficult to debug JavaScript directly in CEF. There's no support for anything like Firebug.

You may also try AppJS.com (Helps to build Desktop Applications. for Linux, Windows and Mac using HTML, CSS and JavaScript)

Also, as pointed out by @Clint, the team at brackets.io (Adobe) created an awesome shell using Chromium Embedded Framework that makes it much easier to get started. It is called the brackets shell: github.com/adobe/brackets-shell Find out more about it here: clintberry.com/2013/html5-desktop-apps-with-brackets-shell

This answer covers what's what in terms of variables and importantly, output size shall be same for input frame and video size.

import cv2

save_name = "output.mp4"
fps = 10
width = 600
height = 480
output_size = (width, height)
out = cv2.VideoWriter(save_name,cv2.VideoWriter_fourcc('M','J','P','G'), fps , output_size )

cap = cv2.VideoCapture(0) # 0 for webcam or you can put in videopath
while(True):
    _, frame = cap.read()
    cv2.imshow('Video Frame', frame)
    out.write(cv2.resize(frame, output_size ))
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
cap.release()
out.release()
cv2.destroyAllWindows()

The following function would recursively iterate through all the directories in the \home\ubuntu directory( whole directory structure under ubuntu ) and apply the necessary checks in else block.

function check {
        for file in $1/*      
        do
        if [ -d "$file" ]
        then
                check $file                          
        else
               ##check for the file
               if [ $(head -c 4 "$file") = "%PDF" ]; then
                         rm -r $file
               fi
        fi
        done

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

$dbc is returning false. Your query has an error in it:

SELECT users.*, profile.* --You do not join with profile anywhere.
                                 FROM users 
                                 INNER JOIN contact_info 
                                 ON contact_info.user_id = users.user_id 
                                 WHERE users.user_id=3");

The fix for this in general has been described by Raveren.

If you strictly want to stick to using button,Then simply create an open window function as follows:

    <script>
function myfunction() {
    window.open("mynewpage.html");
}
</script>

Then in your html do the following with your button:

Join

So you would have something like this:

 <body>
    <script>
function joinfunction() {
    window.open("mynewpage.html");
}
</script>
<button  onclick="myfunction()" type="button" class="btn btn-default subs-btn">Join</button>

Please note that Calendar.getTime() is nondeterministic in the sense that the day time part defaults to the current time.

To reproduce, try running following code a couple of times:

Calendar c = Calendar.getInstance();
c.set(2010, 2, 7); // NB: 2 means March, not February!
System.err.println(c.getTime());

Output eg.:

Sun Mar 07 10:46:21 CET 2010

Running the exact same code a couple of minutes later yields:

Sun Mar 07 10:57:51 CET 2010

So, while set() forces corresponding fields to correct values, it leaks system time for the other fields. (Tested above with Sun jdk6 & jdk7)

Hope this helps!

The previous answer is fine, but I'm one of those guys that's firmly against mixing behavior with presentation (putting JavaScript in my HTML) so I prefer to put my event handling logic in my JavaScript files. Additionally, not all browsers implement event (or e) the same way. You may want to do a check prior to running any logic:

document.onkeydown = TabExample;

function TabExample(evt) {
  var evt = (evt) ? evt : ((event) ? event : null);
  var tabKey = 9;
  if(evt.keyCode == tabKey) {
    // do work
  }
}

Sometimes Window ? Show View does not show the Tasks. Just go to Window ? Show View -> Others and type Tasks in the dialog box.

If you are using parallelMap you'll need to export custom functions to the slave jobs, otherwise you get an error "could not find function ".

If you set a non-missing level on parallelStart the same argument should be passed to parallelExport, else you get the same error. So this should be strictly followed:

parallelStart(mode = "<your mode here>", N, level = "<task.level>")
parallelExport("<myfun>", level = "<task.level>")

The '\0' inside character literals and string literals stands for the character with the code zero. The meaning in C and in Objective C is identical.

To illustrate, you can use \0 in an array initializer to construct an array equivalent to a null-terminated string:

char str1[] = "Hello";
char str2[] = {'H', 'e', 'l', 'l', 'o', '\0'};

In general, you can use \ooo to represent an ASCII character in octal notation, where os stand for up to three octal digits.

Use this code for API 21 or above. This works and gives better result compared to the other answers, it detects perfectly the foreground process.

if (Build.VERSION.SDK_INT >= 21) {
    String currentApp = null;
    UsageStatsManager usm = (UsageStatsManager) this.getSystemService(Context.USAGE_STATS_SERVICE);
    long time = System.currentTimeMillis();
    List<UsageStats> applist = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
    if (applist != null && applist.size() > 0) {
        SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
        for (UsageStats usageStats : applist) {
            mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);

        }
        if (mySortedMap != null && !mySortedMap.isEmpty()) {
            currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
        }
    }

Something like below should suffice :-

String decimalPattern = "([0-9]*)\\.([0-9]*)";  
String number="20.00";  
boolean match = Pattern.matches(decimalPattern, number);
System.out.println(match); //if true then decimal else not  

It seems you're actually talking about an MVC (Model-View-Controller) pattern, where logic is separated into various "tiers". Django, as a framework, follows MVC (loosely). You have models that contain your business logic and relate directly to tables in your database, views which in effect act like the controller, handling requests and returning responses, and finally, templates which handle presentation.

Django isn't just one of these, it is a complete framework for application development and provides all the tools you need for that purpose.

Frontend vs Backend is all semantics. You could potentially build a Django app that is entirely "backend", using its built-in admin contrib package to manage the data for an entirely separate application. Or, you could use it solely for "frontend", just using its views and templates but using something else entirely to manage the data. Most usually, it's used for both. The built-in admin (the "backend"), provides an easy way to manage your data and you build apps within Django to present that data in various ways. However, if you were so inclined, you could also create your own "backend" in Django. You're not forced to use the default admin.

For Windows Users:

In Environment Variables, add a new variable in system variable with name "TESSDATA_PREFIX" and value is "C:\Program Files (x86)\Tesseract-OCR\tessdata"

It's a bit verbose, but i've gotten used to using the hidden .SD variable.

b<-data.table(a=1,b=2,c=3,d=4)
b[,.SD,.SDcols=c(1:2)]

It's a bit of a hassle, but you don't lose out on other data.table features (I don't think), so you should still be able to use other important functions like join tables etc.

You can use $addToSet with the aggregation framework to count distinct objects.

For example:

db.collectionName.aggregate([{
    $group: {_id: null, uniqueValues: {$addToSet: "$fieldName"}}
}])

This worked for me

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        if(tag.equalsIgnoreCase("dashboard")){

            DashboardFragment dashboardFragment = (DashboardFragment)
                    fragmentManager.findFragmentByTag("dashboard");
            if(dashboardFragment!=null) ft.show(dashboardFragment);

            ShowcaseFragment showcaseFragment = (ShowcaseFragment)
                    fragmentManager.findFragmentByTag("showcase");
            if(showcaseFragment!=null) ft.hide(showcaseFragment);

        } else if(tag.equalsIgnoreCase("showcase")){
            DashboardFragment dashboardFragment = (DashboardFragment)
                    fragmentManager.findFragmentByTag("dashboard");
            if(dashboardFragment!=null) ft.hide(dashboardFragment);

            ShowcaseFragment showcaseFragment = (ShowcaseFragment)
                    fragmentManager.findFragmentByTag("showcase");
            if(showcaseFragment!=null) ft.show(showcaseFragment);
        }

        ft.commit();

Git keeps all of its files in the .git directory. Just remove that one and init again.

This post well show you how to find the hide .git file on Windows, Mac OSX, Ubuntu

Try Following Code.

       var oTable = $('#app-config').dataTable(
        {
            "bAutoWidth": false,                                                
            "bDestroy":true,
            "bProcessing" : true,
            "bServerSide" : true,
            "sPaginationType" : "full_numbers",
            "sAjaxSource" : url,                    
            "fnServerData" : function(sSource, aoData, fnCallback) {
                alert("sSource"+ sSource);
                alert("aoData"+ aoData);
                $.ajax({
                    "dataType" : 'json',
                    "type" : "GET",
                    "url" : sSource,
                    "data" : aoData,
                    "success" : fnCallback
                }).success( function(){  alert("This Function will execute after data table loaded");   });
            }

You can use the built-in http module to do an http.request().

However if you want to simplify the API you can use a module such as superagent

The short answer - use square brackets:

if [%1]==[] goto :blank

or (when you need to handle quoted args, see the Edit below):

if [%~1]==[] goto :blank

Why? you might ask. Well, just as Jeremiah Willcock mentioned: http://ss64.com/nt/if.html - they use that! OK, but what's wrong with the quotes?

Again, short answer: they are "magical" - sometimes double (double) quotes get converted to a single (double) quote. And they need to match, for a start.

Consider this little script:

@rem argq.bat
@echo off

:loop 
if "%1"=="" goto :done
echo %1
shift
goto :loop

:done
echo Done.

Let's test it:

C:\> argq bla bla
bla
bla
Done.

Seems to work. But now, lets switch to second gear:

C:\> argq "bla bla"
bla""=="" was unexpected at this time.

Boom This didn't evaluate to true, neither did it evaluate to false. The script DIED. If you were supposed to turn off the reactor somewhere down the line, well - tough luck. You now will die like Harry Daghlian.

You may think - OK, the arguments can't contain quotes. If they do, this happens. Wrong Here's some consolation:

C:\> argq ""bla bla""
""bla
bla""
Done.

Oh yeah. Don't worry - sometimes this will work.

Let's try another script:

@rem args.bat
@echo off

:loop 
if [%1]==[] goto :done
echo %1
shift
goto :loop

:done
echo Done.

You can test yourself, that it works OK for the above cases. This is logical - quotes have nothing to do with brackets, so there's no magic here. But what about spicing the args up with brackets?

D:\>args ]bla bla[
]bla
bla[
Done.

D:\>args [bla bla]
[bla
bla]
Done.

No luck there. The brackets just can't choke cmd.exe's parser.

Let's go back to the evil quotes for a moment. The problem was there, when the argument ended with a quote:

D:\>argq "bla1 bla2"
bla2""=="" was unexpected at this time.

What if I pass just:

D:\>argq bla2"
The syntax of the command is incorrect.

The script won't run at all. Same for args.bat:

D:\>args bla2"
The syntax of the command is incorrect.

But what do I get, when the number of "-characters "matches" (i.e. - is even), in such a case:

D:\>args bla2" "bla3
bla2" "bla3
Done.

NICE - I hope you learned something about how .bat files split their command line arguments (HINT: *It's not exactly like in bash). The above argument contains a space. But the quotes are not stripped automatically.

And argq? How does it react to that? Predictably:

D:\>argq bla2" "bla3
"bla3"=="" was unexpected at this time.

So - think before you say: "Know what? Just use quotes. [Because, to me, this looks nicer]".

Edit

Recently, there were comments about this answer - well, sqare brackets "can't handle" passing quoted arguments and treating them just as if they weren't quoted.

The syntax:

if "%~1"=="" (...)

Is not some newly found virtue of the double quotes, but a display of a neat feature of stripping quotes from the argument variable, if the first and last character is a double quote.

This "technology" works just as well with square brackets:

if [%~1]==[] (...)

It was a useful thing to point this out, so I also upvote the new answer.

Finally, double quote fans, does an argument of the form "" exist in your book, or is it blank? Just askin' ;)

Swift 4.0

Store:

let arrayFruit = ["Apple","Banana","Orange","Grapes","Watermelon"]    

 //store in user default
 UserDefaults.standard.set(arrayFruit, forKey: "arrayFruit")

Fetch:

if let arr = UserDefaults.standard.array(forKey: "arrayFruit") as? [String]{
        print(arr)
    }

This does what you want and overcomes some of the problems in other answers:

import matplotlib.pyplot as plt

labels = ["HHZ 1", "HHN", "HHE"]
colors = ["r","g","b"]

f,axs = plt.subplots(3, sharex=True, sharey=True)

# ---- loop over axes ----
for i,ax in enumerate(axs):
  axs[i].plot([0,1],[1,0],color=colors[i],label=labels[i])
  axs[i].legend(loc="upper right")

plt.show()

... produces ...

If you use Flutter, then you can access it via people.googleapis.com endpoint, code uses google_sign_in library

import 'package:google_sign_in/google_sign_in.dart';

Future<String> getPhotoUrl(GoogleSignInAccount account, String userId) async {
  // final authentication = await account.authentication;
  final url = 'https://people.googleapis.com/v1/people/${userId}?personFields=photos';
  final response = await http.get(
    url,
    headers: await account.authHeaders
  );

  final data = json.decode(response.body);
  return data['photos'].first['url'];
}

You will get something like

{
  resourceName: people/998812322529259873423, 
  etag: %EgQBAzcabcQBAgUH, 
  photos: [{metadata: {primary: true, source: {type: PROFILE, id: 107721622529987673423}}, 
  url: https://lh3.googleusercontent.com/a-/abcdefmB2p1VWxLsNT9WSV0yqwuwo6o2Ba21sh_ra7CnrZ=s100}]
}

where url is an accessible image url.

I have also used a non-generic version, using the new keyword:

public interface IMetadata
{
    Type DataType { get; }

    object Data { get; }
}

public interface IMetadata<TData> : IMetadata
{
    new TData Data { get; }
}

Explicit interface implementation is used to allow both Data members:

public class Metadata<TData> : IMetadata<TData>
{
    public Metadata(TData data)
    {
       Data = data;
    }

    public Type DataType
    {
        get { return typeof(TData); }
    }

    object IMetadata.Data
    {
        get { return Data; }
    }

    public TData Data { get; private set; }
}

You could derive a version targeting value types:

public interface IValueTypeMetadata : IMetadata
{

}

public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{

}

public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
    public ValueTypeMetadata(TData data) : base(data)
    {}
}

This can be extended to any kind of generic constraints.

enum NumberError: Error {
  case NegativeNumber(number: Int)
  case ZeroNumber
  case OddNumber(number: Int)
}

extension NumberError: CustomStringConvertible {
         var description: String {
         switch self {
             case .NegativeNumber(let number):
                 return "Negative number \(number) is Passed."
             case .OddNumber(let number):
                return "Odd number \(number) is Passed."
             case .ZeroNumber:
                return "Zero is Passed."
      }
   }
}

 func validateEvenNumber(_ number: Int) throws ->Int {
     if number == 0 {
        throw NumberError.ZeroNumber
     } else if number < 0 {
        throw NumberError.NegativeNumber(number: number)
     } else if number % 2 == 1 {
         throw NumberError.OddNumber(number: number)
     }
    return number
}

Now Validate Number :

 do {
     let number = try validateEvenNumber(0)
     print("Valid Even Number: \(number)")
  } catch let error as NumberError {
     print(error.description)
  }

Actually in Eclipse Indigo thru Oxygen, you have to go to the Types template Window -> Preferences -> Java -> Code Style -> Code templates -> (in right-hand pane) Comments -> double-click Types and make sure it has the following, which it should have by default:

/**
 * @author ${user}
 *
 * ${tags}
 */

and as far as I can tell, there is nothing in Eclipse to add the javadoc automatically to existing files in one batch. You could easily do it from the command line with sed & awk but that's another question.

If you are prepared to open each file individually, then selected the class / interface declaration line, e.g. public class AdamsClass { and then hit the key combo Shift + Alt + J and that will insert a new javadoc comment above, along with the author tag for your user. To experiment with other settings, go to Windows->Preferences->Java->Editor->Templates.

The answer anhic gave can be very inefficient if you have a large database and the attribute name is present only in some of the documents.

To improve efficiency you can add a $match to the aggregation.

db.collection.aggregate(
    {"$match": {"name" :{ "$ne" : null } } }, 
    {"$group" : {"_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"count" : {"$gt": 1} } }, 
    {"$project": {"name" : "$_id", "_id" : 0} }
)
